|20140251391||Inner-Diameter Quenching Device - An inner-diameter quenching device is provided with a workpiece holding assembly for holding a workpiece to be quenched, a spray cylinder, and a heating coil. The workpiece has a central axis. The spray cylinder is disposed at a first side of the workpiece holding assembly and driven by a lifting assembly to move along the central axis into an inner diameter of the workpiece. The heating coil is disposed at a second side of the workpiece holding assembly and located on and movable along the central axis. The heating coil and the spray cylinder are separated and movable in opposite directions along the same center axis, which can further reduce the size of the quenching device, making it suitable for quenching a small inner-diameter workpiece. Besides, the spray apertures are inclined, so that the cooling liquid can be sprayed out more easily to enhance the quenching effect.||09-11-2014|
|20140251050||LOAD ADJUSTABLE BALL SCREW DEVICE - A ball screw device includes a screw engaged into two nut members for forming a ball guiding passage between the nut members and the screw member and for receiving and engaging with bearing members, and a load applying device is disposed on the screw member and disposed between the nut members and applies a load onto the nut members in order to force and move the nut members away from each other and so as to apply a force onto the ball bearing members and in order to stably anchor and retain the ball bearing members between the nut members and the screw member and in order to facilitate a movement between the nut members and the screw member.||09-11-2014|
|20140222201||DIRECTIONAL POSITION CONTROL METHOD - A directional position control method uses an instructor device and a controller to control motion of a robot, and a directional-control starter is used to actuate a directional control function. The directional-control starter controls the controller to drive the robot to move according to the instructor direction reference by converting the coordinate of the robot into the coordinate of the instructor. The directional position control method allows the movement direction reference of the robot to be defined manually or automatically, so that the robot can be moved based on the instructor direction reference of the instructor, allowing the operator to operate the robot by intuition without too much discretion, consequently reducing difficulty and error in operating the robot. Besides, the operator can control the robot by staying at the location where the instructor is located, without standing close to the robot, therefore, improving safety of operating the robot.||08-07-2014|
|20140174232||ROLLER ELEMENT RETAINER FOR BALL SCREW DEVICE - A motion guide device includes a ball nut attached onto a shaft and having helical grooves for forming a ball guiding raceway between the ball nut and the elongated shaft and for receiving ball bearing elements, a circulating device attached to the ball nut and having a pathway communicative with the raceway for forming an endless ball guiding passage between the ball nut and the elongated shaft and the circulating device and for engaging with bearing elements, and a retaining device includes a shorter chain for engaging into the helical grooves or raceway of the screw shaft and the ball nut, and a longer chain for engaging into the pathway of the circulating device.||06-26-2014|
|20140083224||EXTERNAL CIRCULATION TYPE BALL SCREW DEVICE - The invention provides an external circulation type ball screw device comprising screw shaft and nut having first and second screw grooves. A circulation member comprises first leg, second leg and connection portion. The first leg comprises a first end surface having first inner and outer points, and the second leg comprises a second end surface having second inner and outer points; first and second entrances formed on the first and second end surfaces of circulation passage; first and second thickness respectively provided between the first entrance and the first inner and outer points thereof; the second thickness being greater than the first; the third and fourth thickness respectively provided between the second entrance and the second inner and outer points thereof; the fourth thickness being greater than the third. The groove wall of the second screw groove occupied and the occurrence of broken teeth of the nut are reduced.||03-27-2014|
|20140033847||MOTION TRANSMISSION MODULE WITH A COOLING DEVICE - A motion transmission module with a cooling device is aimed at solving the disadvantage of the conventional motion transmission module that the cooling structure of the conventional motion transmission module would increase the length or outer diameter of the nut. The nut is formed with a flat surface for mounting the cooling device, so that the length of the nut won't be increased. Furthermore, the cooling device also serves as a positioning block to fix the return member, it doesn't increase the outer diameter of the nut.||02-06-2014|
|20130313302||FEEDING DEVICE - A feeding device includes a fixing base. A motor is fixed to the fixing base. The motor has an output axle. A transmission axle is fixedly connected to the output axle. The feeding device further includes a feeding block having a side fixedly connected to the transmission axle. The feeding block has a feeding notch. The feeding notch is formed around the transmission axle circumferentially. Hence, once a slender material enters the rotational space of the feeding block, the motor drives the feeding block to rotate, whereas the slender material is pressed by the feeding notch of the feeding block and sent out as a result of the continuous rotation of the feeding block. Hence, the feeding device not only enables continuous material conveyance but also allows the slender material to be conveyed smoothly even when the slender material is slightly bent or deformed.||11-28-2013|

|20120037457||Lubrication monitoring system for linear transmission device - A lubrication monitoring system for monitoring the lubricative state of two relatively movable elements of a linear transmission device includes a contact resistance capturing device and a processing unit. The contact resistance capturing device for detecting the contact resistance between the two elements and converting it into a corresponding value. A maximum delay time and a threshold value are preset in the processing unit. A period of time during which the linear transmission device starts to run and then the corresponding value reaches the threshold value defines a delay time. If the specific value of the delay time to the maximum delay time is larger than or equal to a predetermined specific one, it will be judged that the lubrication needs resupply. Therefore, monitoring the lubricative state as the linear transmission device is accelerated can get correct lubricative state to enable correct lubrication resupply.||02-16-2012|
