Description

Technical Field

[0001] The utility model relates to the technical field of plastic pallet fixing clamps, in particular to a fixing clamp used for plastic pallet processing. Background Art

[0002] In the production and post-processing of plastic pallets, fixtures are used as equipment for positioning and clamping workpieces quickly, accurately and stably, which plays an important role in improving production efficiency and ensuring product quality. With the rapid development of industrial production, plastic pallets have been widely used in logistics, transportation, warehousing management and various production links. Due to the variety of sizes and shapes of plastic pallets, it is required that the fixtures used in the processing process can adapt to pallets of different sizes and types, quickly change and stably clamp the workpiece.

[0003] At present, traditional fixtures are mostly single clamping methods, and most are custom-designed to fit pallets of specific sizes. Different sizes of pallets need to be fixed and processed with different fixtures, which not only reduces production efficiency but also increases production costs. For example, larger plastic pallets need to be stably fixed during processing to facilitate operations such as grinding, cutting or drilling, while smaller plastic pallets require rotational grinding to improve processing efficiency. However, current fixtures often cannot have both fixed and rotational clamping functions, which limits processing efficiency and workpiece handling flexibility.

[0004] Therefore, those skilled in the art have proposed a fixing fixture for processing plastic pallets. Utility Model Content

When in contact, the spring will be compressed, which allows the contact plate to maintain sufficient pressure while ensuring a soft connection with the pallet without damaging the pallet. This is suitable for use on some round or small pallets and is convenient for rotation and grinding.

[0010] As a preferred embodiment, a placement plate with a hollow structure is provided above the fixed plate and below the contact disk, and the four bottom corners of the placement plate are fixedly connected with legs, and the legs are fixedly connected to the top of the fixed plate, and the internal rotation of the placement plate is connected with a bidirectional screw rod, and the outer side of the bidirectional screw rod is symmetrically threaded with two moving blocks, and four strip grooves are symmetrically provided on the placement plate, and the moving blocks extend to the top of the placement plate through the corresponding strip grooves and are fixedly connected with a clamping plate.

The two clamping plates can contact the pallet to achieve clamping work. This is suitable for use with some larger pallets and is convenient for fixed grinding.

[0012] As a preferred embodiment, the clamping plate is configured as an L-shaped structure and a slanted notch is provided on one side for facilitating insertion of the tray.

[0014] As a preferred embodiment, a driving motor is fixedly connected to one side of the placement plate, and an output end of the driving motor extends to the inside of the placement plate and is fixedly connected to one end of the bidirectional lead screw.

[0015] Through the above technical means, the drive motor can provide rotational power for the bidirectional screw.

[0016] As a preferred embodiment, three fixed blocks are symmetrically fixedly connected to the bottom of the placement plate, wherein two fixed blocks far away from each other are slidably connected to the inside of light rods, the fixed block in the middle position is threadedly connected to an adjusting screw, a baffle is fixedly connected between the adjusting screw and one end of the light rod, a limiting plate is fixedly connected between the other ends of the two light rods, and the other end of the adjusting screw passes through the limiting plate, extends to the outside of the placement plate and is fixedly connected to an adjusting knob.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] In the utility model, the adjusting frame is lifted and lowered by the lifting screw rod, so that the center position can be adjusted according to the height of different pallets.

[0032] In summary, the adjustment frame 24 is lifted and lowered by the rotation of the lifting screw rod 6, and the two electric push rods 4 are moved by the adjustment frame 24, so that the center position can be adjusted according to the height of different pallets.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, the output ends of the electric push rods 4 are rotatably connected to the connecting plates 7, the interior of the connecting plates 7 are symmetrically slidably connected to the slide bars 8, one end of the slide bars 8 is provided with a sealing plate, one end of the corresponding two slide bars 8 is fixedly connected with a contact plate 9, the outer side of the slide bars 8 and between the connecting plates 7 and the contact plates 9 are sleeved with springs 10, and the outer side of the contact plates 9 is provided with a soft connection pad;

[0034] To sum up: the movement of the electric push rod 4 drives the connecting plate 7 to move, and then drives the contact plate 9 to move, so that the two contact plates 9 come into contact with the pallet. When in contact, the spring 10 will be compressed, which allows the contact plate 9 to maintain sufficient pressure while ensuring a soft connection with the pallet without damaging the pallet. This is suitable for use with some round or small pallets and is convenient for rotation and grinding.

[0035] like Figure 3 and Figure 4 As shown, a placement plate 11 with a hollow structure is arranged above the fixed plate 1 and below the contact plate 9, and legs 12 are fixedly connected to the four corners of the bottom of the placement plate 11, and the legs 12 are fixedly connected to the top of the fixed plate 1, and a bidirectional screw rod 13 is rotatably connected inside the placement plate 11, and two moving blocks 14 are symmetrically threadedly connected to the outer side of the bidirectional screw rod 13, and four strip grooves 15 are symmetrically arranged on the placement plate 11, and the moving blocks 14 extend to the top of the placement plate 11 through the corresponding strip grooves 15 and are fixedly connected to a clamping plate 16;

[0036] To sum up: the movement of the bidirectional screw rod 13 drives the two moving blocks 14 to move, and then the moving blocks 14 drive the clamping plates 16 to move. The two clamping plates 16 can contact the pallet to achieve clamping work, which is suitable for use with some larger pallets and is convenient for fixed grinding.

After the center position is adjusted, the connection plate 7 is moved by the movement of the electric push rod 4, and then the contact plate 9 is moved, so that the two contact plates 9 are in contact with the pallet. When in contact, the spring 10 will be compressed, so that the contact plate 9 can maintain sufficient pressure while ensuring a soft connection with the pallet without damaging the pallet. This is suitable for some round or small pallets and is convenient for rotation and grinding.
