[0002] The existing workpiece locking devices have the following shortcomings: First, they are complicated to operate and have low clamping efficiency; second, when locking the workpiece, the workpiece may be damaged. Utility Model Content

[0003] The purpose of this invention is to provide a workpiece multi-point synchronous locking device that is easy to operate and has high clamping efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A multi-point synchronous locking device for workpieces includes a driving device, a transmission mechanism, a first clamping body, a second clamping body, a third clamping body, a first sliding mechanism, a second sliding mechanism, and a third sliding mechanism. The driving device drives the first sliding mechanism, the second sliding mechanism, and the third sliding mechanism to move synchronously through the transmission mechanism. The first sliding mechanism, the second sliding mechanism, and the third sliding mechanism respectively drive the first clamping body, the second clamping body, and the third clamping body to move, so as to lock and fix the workpiece at multiple points synchronously through the first clamping body, the second clamping body, and the third clamping body.

[0006] Furthermore, the first sliding mechanism includes a longitudinal guide rail and a longitudinal slider, the longitudinal slider being disposed on the longitudinal guide rail and capable of sliding along the longitudinal guide rail, and the first clamping body being disposed on the longitudinal slider.

[0007] Furthermore, the second sliding mechanism includes a left transverse guide rail and a left transverse slider; the third sliding mechanism includes a right transverse guide rail and a right transverse slider. The left transverse guide rail and the right transverse guide rail are disposed on the worktable and are located on the same straight line. The second clamping body and the third clamping body are respectively disposed on the left transverse slider and the right transverse slider. The left transverse slider and the right transverse slider are respectively disposed on the left transverse guide rail and the right transverse guide rail. The left transverse guide rail and the right transverse guide rail are disposed on both sides of the longitudinal guide rail and are perpendicular to the longitudinal guide rail.

[0008] Furthermore, the first clamping body, the second clamping body, and the third clamping body have the same structure. The second clamping body includes a support base and a clamping member. The clamping member is laterally fixed on the support base, and the support base is located on the left lateral slider of the second sliding mechanism.

[0009] Furthermore, the transmission mechanism includes a left transmission plate, a right transmission plate, a left transmission column, and a right transmission column. The left transmission plate and the right transmission plate are respectively provided with a left elongated hole and a right elongated hole. One end of the left transmission plate and the right transmission plate is fixed on the longitudinal slider. The left elongated hole on the left transmission plate and the right elongated hole on the right transmission plate are respectively inserted into the left transmission column and the right transmission column and can slide relative to the left transmission column and the right transmission column. The left transmission column and the right transmission column are respectively erected on the left transverse slider and the right transverse slider. The left transmission plate and the right transmission plate form an eight-shaped structure.

[0010] Furthermore, the driving device directly drives the longitudinal slider to slide along the longitudinal guide rail, and the longitudinal slider simultaneously drives the left and right transverse sliders to move through the left and right transmission plates respectively.

[0011] Furthermore, the left and right transmission plates are curved plate structures, and the included angle at the bend of the left and right transmission plates is greater than 90°.

[0012] Furthermore, the clamping component includes a clamping block, a pressure sensor, a spring, a clamping rod, and a retaining ring. The side wall of the clamping block has a mounting hole and a lead wire hole. The pressure sensor is installed at the bottom of the mounting hole, and the data line on the pressure sensor passes through the lead wire hole and is electrically connected to the controller. The clamping rod is inserted into the mounting hole, and the spring is installed in the mounting hole and located between the clamping rod and the pressure sensor. The clamping rod has a limiting boss. The retaining ring is fixed to the mounting hole on the clamping block by screws. The clamping end of the clamping rod extends out of the clamping block through the retaining ring. The retaining ring is used to block the limiting boss on the clamping rod to prevent the clamping rod from disengaging from the mounting hole.

[0013] Furthermore, the clamping end of the clamping rod is fitted with a wear-resistant rubber sleeve.

[0014] Furthermore, the driving device is an electric push rod or a cylinder.

[0015] The beneficial effects of this utility model are as follows: This application adopts a multi-point synchronous locking method for the workpiece, requiring only one drive device to achieve multi-point synchronous locking, which is convenient to operate and has high clamping efficiency. This application also improves the clamping component. When the clamping rod clamps the workpiece, the clamping rod retracts, and the pressure sensor transmits the pressure to the controller. When the clamping force of the clamping rod on the workpiece reaches the preset value, the controller shuts off the drive device to prevent the drive device from continuing to work and damaging the workpiece. In addition, a wear-resistant rubber sleeve is fitted on the clamping end of the clamping rod to prevent wear of the clamping rod. Attached Figure Description

[0026] The transmission mechanism includes a left transmission plate 9, a right transmission plate 10, a left transmission column 11, and a right transmission column 12. The left transmission plate 9 and the right transmission plate 10 are curved plate structures, and the included angle at the bend of the left transmission plate 9 and the right transmission plate 10 is greater than 90°. The left transmission plate 9 and the right transmission plate 10 are respectively provided with a left elongated hole 13 and a right elongated hole 14. One end of the left transmission plate 9 and the right transmission plate 10 is fixed on the longitudinal slider 52. The left elongated hole 13 on the left transmission plate 9 and the right elongated hole 14 on the right transmission plate 10 are respectively inserted into the left transmission column 11 and the right transmission column 12 and can slide relative to the left transmission column 11 and the right transmission column 12.

The left transmission plate 9 and the right transmission plate 10 are assembled into a figure-eight structure.

[0027] The driving device 1 directly drives the longitudinal slider 52 to slide along the longitudinal guide rail 51.

When the clamping rod 18 clamps the workpiece, the clamping rod 18 retracts, and the pressure sensor 16 transmits the pressure to the controller. When the clamping force of the clamping rod 18 on the workpiece reaches the preset value, the controller shuts off the drive device 1 to prevent the drive device 1 from continuing to work and damaging the workpiece.
