[0003] While the aforementioned patent allows the plastic pallet to be clamped and secured in all four directions, each side is driven by a separate motor, which not only increases operating costs but also makes control more complex. Furthermore, if the clamp is damaged, the motor is difficult to repair, and replacing the motor requires even greater expense, thus limiting its practicality. Utility Model Content

[0004] The purpose of the utility model is to provide a fixing fixture for processing plastic pallets, which has the advantages that a single motor can drive the fixture to clamp various types of plastic pallets in four directions and facilitate position adjustment after the plastic pallets are clamped and fixed.

[0005] The above technical objectives of the present utility model are achieved through the following technical solutions: A fixing fixture for processing plastic pallets, comprising a processing table, a motor is fixedly installed on one side of the bottom of the processing table, the output end of the motor is fixedly connected to a disc gear, one side of the surface of the disc gear is provided with a profiled circular sleeve that is rotatably sleeved with the inside of the processing table, the surface of the profiled circular sleeve is fixedly sleeved with a ring gear that meshes with the disc gear, the top of the profiled circular sleeve is fixedly connected with an annular bevel gear, and slide grooves are symmetrically provided on the four sides inside the processing table, the interiors of the four slide grooves are all rotatably connected with a first screw, the ends of the four first screws close to each other are fixedly connected with a bevel gear that meshes with the annular bevel gear, the surfaces of the four first screws are threadedly sleeved with a first threaded sleeve that is slidably connected to the slide groove, and the tops of the four first threaded sleeves are fixedly connected to a second threaded sleeve.

[0006] Using this technical solution, turning on the motor synchronously drives the four first threaded sleeves toward or away from each other, allowing the first threaded sleeves to slide the top clamp closer together, thereby clamping and securing the plastic pallet in four directions. This allows a single motor to drive the clamp to clamp the plastic pallet in four directions, reducing operating costs and improving practicality. The clamping plate can be freely adjusted to clamp other surfaces of unequal-sided plastic pallets, achieving four-directional clamping for a variety of plastic pallets and improving the practicality of the clamp. The position of the plastic pallet can also be adjusted and moved, facilitating its processing.

[0007] The utility model is further configured as follows: the interiors of the four second threaded sleeves are all threadedly connected with second screw rods, the ends of the four second screw rods close to each other are fixedly connected with a clamping plate, and the side of the clamping plate away from the second screw rod is rotatably connected with a roller.

[0008] By adopting the above technical solution, not only can various types of plastic pallets be clamped in four directions under force, but the position of the plastic pallets can also be adjusted and moved, thereby facilitating the processing of the plastic pallets.

[0009] The utility model is further configured as follows: four corners of the bottom of the processing table are fixedly connected with anti-skid bottom plates.

[0010] By adopting the above technical solution, the ground contact area at the bottom of the processing table is increased, and the stability of the processing table placement is improved.

[0011] The utility model is further configured as follows: a vacuum pump is fixedly installed on the other side of the bottom of the processing table, a vacuum suction cup is fixedly installed at the center of the top of the processing table, and the input end of the vacuum pump is fixedly connected to a connecting pipe fixedly connected to the vacuum suction cup.

[0012] By adopting the above technical solution, the vacuum pump is turned on to suck the inside of the vacuum suction cup through the connecting pipe, thereby generating negative pressure inside the vacuum suction cup, so that the vacuum suction cup can absorb the plastic pallet and further strengthen the plastic pallet.

[0013] The utility model is further configured as follows: the four slide grooves are all opened through the interior of the processing table.

[0014] By adopting the above technical solution, the debris processed on the plastic pallet can fall to the ground through the chute, thereby avoiding accumulation in the chute and blocking the sliding of the first threaded sleeve.

[0015] The utility model is further configured as follows: an anti-slip sleeve is fixedly sleeved on the surface of the drum.

[0016] By adopting the above technical solution, the friction force on the roller surface is increased and the clamping stability of the plastic pallet is improved.

[0017] The utility model is further configured as follows: a rotating handle is fixedly mounted on one end of each of the four second screw rods away from the clamping plate.

[0018] The above technical solution makes it easy to rotate the handle to drive the second screw to rotate.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. By turning on the motor, the four first threaded sleeves can be synchronously driven to move closer or further away from each other, so that the first threaded sleeves can drive the top clamp to slide closer, clamping the plastic pallet in four directions. This allows a single motor to drive the clamp to clamp the plastic pallet in four directions, thereby reducing operating costs and improving practicality.

[0021] 2. By freely adjusting the clamping plate, it can clamp the other sides of the unequal-sided plastic pallet, achieving force clamping in four directions for various types of plastic pallets, improving the practicality of the fixture. At the same time, the position of the plastic pallet can also be adjusted and moved, making it easier to process the plastic pallet. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 、 Figure 2 、 Figure 3 The top of the four first threaded sleeves 10 is fixedly connected to the second threaded sleeve 11; the four first threaded sleeves 10 are fixedly connected to the second threaded sleeve 11, and the top of the four first threaded sleeves 10 is fixedly connected to the second threaded sleeve 11; by turning on the motor 2, the four first threaded sleeves 10 can be synchronously driven to move closer or farther away from each other, so that the first threaded sleeve 10 can drive the top fixture to slide closer, thereby clamping and fixing the plastic pallet in four directions. It is possible to use a single motor to drive the clamp to clamp the plastic pallet in four directions, thereby reducing operating costs and improving practicality.

[0030] refer to Figure 1 、 Figure 2 The four corners of the bottom of the processing table 1 are fixedly connected with anti-skid bottom plates 19, which increase the ground area of the bottom of the processing table 1 and improve the stability of the processing table 1.

[0031] refer to Figure 1 、 Figure 2 A vacuum pump 16 is fixedly installed on the other side of the bottom of the processing table 1, and a vacuum suction cup 18 is fixedly installed at the center of the top of the processing table 1. The input end of the vacuum pump 16 is fixedly connected with a connecting pipe 17 that is fixedly connected to the vacuum suction cup 18. By turning on the vacuum pump 16 and using the connecting pipe 17 to suck into the inside of the vacuum suction cup 18, negative pressure is generated inside the vacuum suction cup 18, so that the vacuum suction cup 18 can adsorb the plastic pallet and further strengthen the plastic pallet.

[0032] refer to Figure 2 The four chutes 7 are all opened through the interior of the processing table 1, so that the debris processed on the plastic pallet can fall to the ground through the chutes 7, thereby avoiding accumulation in the chutes 7 and blocking the sliding of the first threaded sleeve 10.

[0033] Briefly describe the process: Turning on motor 2 drives disc gear 3 to rotate and mesh with ring gear 5, which in turn rotates the tooling sleeve 4 inside processing table 1, further driving the top ring bevel gear 6. Ring bevel gear 6 then meshes with four bevel gears 9, which in turn drive four first screws 8 to rotate synchronously within chute 7. The first screws 8 then engage with the first threaded sleeve 10, which, within the position of chute 7, drives the top clamps to slide closer together, thereby clamping and securing the plastic pallet in four directions.

[0034] Example 2:

[0035] refer to Figure 1 、 Figure 2 、 Figure 4 A fixture for processing plastic pallets comprises four second threaded sleeves 11, each threadedly connected to a second screw rod 12. A clamping plate 13 is fixedly connected to the adjacent ends of the four second screw rods 12. A roller 14 is rotatably connected to the side of the clamping plate 13 facing away from the second screw rod 12. The clamping plates 13 can be freely adjusted to clamp other surfaces of unequal-sided plastic pallets, achieving four-way force clamping for various types of plastic pallets, improving the fixture's practicality. The position of the plastic pallet can also be adjusted and moved, facilitating its processing.

[0036] refer to Figure 2 、 Figure 4 The surface of the roller 14 is fixedly sleeved with an anti-slip sleeve 15 to increase the friction force on the surface of the roller 14 and improve the clamping stability of the plastic pallet.

[0037] refer to Figure 1 、 Figure 2 A rotating handle 20 is fixedly mounted on one end of the four second screw rods 12 away from the clamping plate 13, so that the rotating handle 20 can be twisted to drive the second screw rods 12 to rotate.

[0038] Brief description of the usage process: By rotating the second screw 12 and engaging the second threaded sleeve 11, the second screw 12 can push the clamping plate 13 in one direction to slide further forward or backward. Since the first threaded sleeve 10 will drive the clamping plate 13 to slide synchronously, the clamping plate 13 can only clamp plastic pallets with equal sides. Therefore, while the second screw 12 drives the clamping plate 13 to slide further, it can clamp other sides of plastic pallets with unequal sides. At the same time, the clamping plate 13 on one side is slid toward the side away from the plastic pallet, so that this side of the plastic pallet lacks support. Therefore, by rotating the roller 14 inside the clamping plate 13, the plastic pallet can slide toward this side and adjust the position of the plastic pallet. In addition, the other sides can also be adjusted in this way, which facilitates the processing of the plastic pallet.

[0039] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
