[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 3The utility model provides an embodiment: a tool for a PET engraving machine, including a machine table 1, the machine table 1 is a PET engraving machine, which is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The PET engraving machine can engrave the workpiece. The position of the engraving head on the machine table 1 can be changed by manipulating the machine table 1. The upper surface of the machine table 1 is fixedly connected with a base 2. The workpiece to be engraved can be placed on the base 2. The base 2 is located directly below the engraving head on the machine table 1. A clamping component is arranged inside the base 2. The clamping component can clamp the workpiece to be engraved to prevent the workpiece from sliding during engraving, causing the engraving position to shift and affecting the engraving accuracy of the PET engraving machine. A clamping component is arranged on the upper surface of the base 2, which can clamp the workpiece to be engraved to prevent the workpiece from warping. To ensure the stability of the workpiece during the engraving process, the clamping assembly includes a pull rod 31, and a pull ring 37 is fixedly connected to the front surface of the pull rod 31. The pull ring 37 is convenient for gripping, and a positioning block 32 is fixedly connected to the rear surface of the pull rod 31. Pulling the pull ring 37 can drive the positioning block 32 and the pull rod 31 to move synchronously. A connecting rod 33 is hinged on the left surface of the positioning block 32. When the positioning block 32 moves, it will squeeze the connecting rod 33 to make the connecting rod 33 swing. A slider 34 is hinged on the left surface of the connecting rod 33. The swinging connecting rod 33 can drive the slider 34 to move. A splint 35 is fixedly connected to the upper surface of the slider 34. The slider 34 and the splint 35 will move synchronously. A rubber pad 36 is fixedly connected to the right surface of the splint 35. When clamping the workpiece, the rubber pad 36 will directly contact the workpiece. The rubber pad 36 is soft in texture and can prevent the clamping force from being too large and causing wear on the workpiece surface.

[0031] Reference Figure 1 - Figure 3 The clamping assembly also includes a slot 301, and the inner wall of the base 2 is elastically connected to a block 38 through a compression spring 39. The shape and size of the block 38 and the slot 301 match. The front surface of the block 38 is fixedly connected to a shift block 311, and shifting the shift block 311 can drive the block 38 to move synchronously.

[0032] Reference Figure 1 , Figure 2 , Figure 4 The clamping assembly includes a threaded rod 41. A pressing plate 42 is passed through and slidably connected to the front surface of the clamping plate 35. The pressing plate 42 slides longitudinally. A pressing block 43 is fixedly connected to the lower surface of the pressing plate 42. The pressing plate 42 and the pressing block 43 move synchronously.

[0033] Reference Figure 1 , Figure 2 , Figure 4The threaded rod 41 passes through and is threadedly connected to the upper surface of the pressure plate 42. Rotating the threaded rod 41 can drive the pressure plate 42 to move longitudinally. The threaded rod 41 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The threaded rod 41 is self-locking. When the threaded rod 41 stops rotating, the pressure plate 42 will stop moving. The pressure plate 42 is set to a concave shape, and the lower surface of the pressure block 43 is set to a rubber material. The lower surface of the pressure block 43 is in direct contact with the upper surface of the workpiece. The bottom surface of the rubber material can reduce the wear on the workpiece. The threaded rod 41 passes through and is rotatably connected to the upper surface of the clamp 35.

[0034] Reference Figure 1 - Figure 3 The pull rod 31 passes through and is slidably connected to the front surface of the base 2 , the positioning block 32 is slidably connected to the inner wall of the bottom end of the base 2 , and the slider 34 passes through and is slidably connected to the upper surface of the base 2 .

[0035] Reference Figure 1 - Figure 3 There are two groups of connecting rods 33, sliders 34, clamps 35, and rubber pads 36. The two groups of connecting rods 33, sliders 34, clamps 35, and rubber pads 36 are symmetrically arranged with respect to the center line of the base 2. The clamps 35 on both sides can clamp the workpiece synchronously from the left and right sides to ensure that the workpiece is centered and the stability of the workpiece is ensured.

[0036] Reference Figure 1 - Figure 3 The card slot 301 is opened on the left surface of the pull rod 31. There are multiple groups of card slots 301, which are evenly distributed on the left surface of the pull rod 31 in the front-to-back direction. The card block 38 is slidably connected to the inner wall of the base 2. One end of the compression spring 39 is fixedly connected to the left surface of the card block 38, and the other end of the compression spring 39 is fixedly connected to the inner wall on the left side of the base 2. When the card block 38 moves to the left, it will squeeze the compression spring 39 to generate a reaction force.

[0037] Reference Figure 1 - Figure 3 The shift block 311 passes through and is slidably connected to the front surface of the base 2. The shift block 311 is set to be L-shaped, and the rear surface of the card block 38 is set to be an arc surface. When the arc surface of the card block 38 is squeezed, the card block 38 will move to the left. The card block 38 is inserted into the inner wall of the card slot 301. The card block 38 moving to the left will disengage from the card slot 301 to release the limitation on the pull rod 31. The front surface of the card block 38 is a plane. When the front surface of the card block 38 is squeezed, the card block 38 will not be displaced, and it can play a role of one-way limitation.

[0038] Working principle: When the device is used, first place the workpiece to be engraved on the upper surface of the base 2, and then pull the pull ring 37 forward to drive the pull rod 31 and the positioning block 32 to move forward, and the pull rod 31 moving forward will drive the slot 301 to move forward, and the slot 301 will squeeze the arc surface of the rear surface of the block 38 when it moves forward, and the arc surface of the block 38 will move to the left when it is squeezed, and the block 38 moving to the left will disengage from the slot 301 to release the limit on the pull rod 31 and squeeze the compression spring 39 to generate a reaction force, and the positioning block 32 moving forward will squeeze the connecting rod 33 to make the connecting rod 33 swing, and the swinging connecting rod 33 will drive the sliders 34 and the clamping plates 35 on both sides to move toward the center of the base 2 to clamp the workpiece, and when the rubber pad 36 is in close contact with the surface of the workpiece, stop moving the pull rod 31, and the block 38 will move to the right under the push of the reaction force of the compression spring 39 and plug into the slot 301 to limit the pull rod 31, thereby ensuring the stability of the device.

[0039] After the device is clamped, the threaded rod 41 is rotated to drive the pressure plate 42 and the pressure block 43 to move downward until the lower surface of the pressure block 43 presses the workpiece, and the threaded rod 41 stops rotating. Under the influence of the self-locking property of the threaded rod 41, the positions of the pressure plate 42 and the pressure block 43 will be stabilized, and the workpiece can be stably pressed to prevent the workpiece from warping, thereby ensuring stability during processing.

[0040] Then start the machine 1 to start processing the workpiece. After the processing is completed, turn off the machine 1 and reverse the threaded rod 41 to drive the pressure plate 42 and the pressure block 43 to move upward to release the pressure on the workpiece. After the pressure is released, push the block 311 to the left to drive the clamping block 38 to move to the left and disengage the clamping slot 301 to release the limit on the pull rod 31. After the limit is released, move the pull ring 37 backward to drive the pull rod 31 and the positioning block 32 to move backward. The positioning block 32 moving backward will squeeze the connecting rod 33 to make the connecting rod 33 swing in the opposite direction. The connecting rod 33 swinging in the opposite direction will drive the sliders 34 and the clamps 35 on both sides to move to the left and right sides of the base 2 to release the clamping of the workpiece, and then remove the workpiece.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
