Description

Technical Field

[0001] This utility model relates to the field of refrigerated pallet processing technology, and in particular to a positioning fixture for pallet processing. Background Technology

[0002] Refrigerated pallets are load-bearing tools designed specifically for low-temperature environments (such as refrigerated trucks, cold storage, and cold chain shelves). Their core function is to maintain low temperatures while enabling stable stacking, rapid turnover, and efficient loading and unloading of goods (such as fresh produce, pharmaceuticals, and frozen foods). They possess both low-temperature adaptability and logistics load-bearing capacity, and are often made of materials such as HDPE (high-density polyethylene), modified PP (polypropylene), or stainless steel.

[0003] Refrigerated pallets must be strictly matched with the forks of cold chain forklifts, the shelf spacing of cold storage racks, and the dimensions of refrigerated truck bodies. If positioning is lacking during processing, it can easily lead to deviations in the length and width of the pallet and crooked corners, making it impossible to pick up and stack them properly. Therefore, during the processing of refrigerated pallets, positioning fixtures are needed to position the refrigerated pallets to prevent displacement during the processing.

[0004] Existing positioning fixtures for refrigerated pallets are mostly designed for one-to-one dimensions. However, the specifications of refrigerated pallets may change depending on their usage requirements. When faced with changes in the width, height, and depth of refrigerated pallets, positioning components need to be replaced frequently, making it impossible to quickly switch production specifications and increasing tooling changeover time. Based on the above problems, this application proposes a positioning fixture for pallet processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for pallet processing, which solves the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A positioning fixture for pallet processing includes a mounting base. A horizontal adjustment component is provided on the top of the mounting base. A rectangular plate is provided on the top of the mounting base via the horizontal adjustment component. A vertical movement component is provided on the top of the rectangular plate. An upper clamping plate is provided on the bottom of the rectangular plate via the vertical movement component. Mounting plates are fixedly provided on both the front and rear sides of the mounting base. A mounting hole is provided through the top of the mounting plate.

[0007] Preferably, the lateral adjustment assembly includes a mounting pole fixedly installed on the top of the mounting base, a rectangular frame fixedly installed on the top of the mounting pole, an adjustment column slidably installed inside the rectangular frame, an internally threaded sleeve fixedly installed on the top of the rectangular frame, a star-shaped knob threaded inside the internally threaded sleeve, the star-shaped knob being slidably connected to the rectangular frame, the bottom end of the star-shaped knob contacting the top of the rectangular frame, a side clamping plate fixedly installed at the bottom of the adjustment column, and an auxiliary component installed at the bottom of the side clamping plate.

[0008] Preferably, the auxiliary component includes an installation groove formed at the bottom of the side clamp and a limiting plate fixedly installed at the bottom of the side clamp. A ball bearing is overlapped inside the installation groove, and a limiting groove is provided through the surface of the limiting plate. The inner wall of the limiting groove overlaps with the surface of the ball bearing.

[0009] Preferably, a protective pad is fixedly provided on the side of the side clamp near the middle of the mounting base. The protective pad is rectangular and made of rubber.

[0010] Preferably, the vertical moving assembly includes a mounting housing fixedly installed on the top of the rectangular plate. A worm gear is rotatably mounted inside the mounting housing. A hand handle is fixedly mounted on the front side of the worm gear. A worm wheel is meshed on the surface of the hand handle. An internally threaded tube is fixedly mounted inside the worm wheel. The internally threaded tube is rotatably mounted inside the rectangular plate. A screw is threaded inside the internally threaded tube. A guide sleeve is slidably mounted on the surface of the screw. The guide sleeve is fixedly mounted on the upper side wall of the mounting housing. A fixing plate is fixedly mounted on the bottom end of the screw. The fixing plate is fixedly mounted on the top of the upper clamping plate.

[0011] Preferably, a second protective pad is fixedly provided at the bottom of the upper clamping plate. The second protective pad has a rectangular structure and is made of rubber.

[0012] Preferably, the number of adjustment columns is four, and the four adjustment columns are symmetrically distributed, with two adjustment columns forming a group.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the positioning fixture for pallet processing can be adjusted according to the length of the refrigerated pallet by adjusting the components. At the same time, the upper clamping plate is moved by the vertical moving components, so that the upper clamping plate can clamp refrigerated pallets of different heights. Moreover, the vertical moving components can lock the position of the upper clamping plate, thereby making the positioning of the refrigerated pallet more stable. This allows the positioning fixture to be applied to refrigerated pallets of different specifications, avoiding the need to spend a lot of time changing the positioning fixture when the specifications of the refrigerated pallets change.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Refer to Figure 1-5A positioning fixture for pallet processing includes a mounting base 1. A lateral adjustment assembly is provided on the top of the mounting base 1. The lateral adjustment assembly includes a mounting rod 2 fixedly mounted on the top of the mounting base 1. A rectangular frame 3 is fixedly mounted on the top of the mounting rod 2. Adjusting columns 4 are slidably arranged inside the rectangular frame 3. The number of adjusting columns 4 is four, and the four adjusting columns 4 are symmetrically distributed, with two adjusting columns 4 forming a group. An internally threaded sleeve 5 is fixedly mounted on the top of the rectangular frame 3. A star-shaped knob 6 is threaded inside the internally threaded sleeve 5. The star-shaped knob 6 is slidably connected to the rectangular frame 3. The bottom end of the star-shaped knob 6... Contacting the top of the rectangular frame 3, the bottom of the adjusting column 4 is fixedly equipped with a side clamp 7. An auxiliary component is located at the bottom of the side clamp 7. Rotating the plum blossom knob 6 pulls the side clamp 7, causing the adjusting column 4 to slide inside the rectangular frame 3, making the side clamp 7 contact the refrigerated tray. Then, rotating the plum blossom knob 6 in the opposite direction causes it to press against the adjusting column 4, thus fixing the adjusting column 4 inside the rectangular frame 3. A rectangular plate 8 is mounted on the top of the mounting base 1 via a horizontal adjustment component. A vertical movement component is located on the top of the rectangular plate 8, and the bottom of the rectangular plate 8 is moved vertically... The component is equipped with an upper clamping plate 17. The vertically moving component includes a mounting housing 9 fixedly installed on the top of the rectangular plate 8. A worm gear 10 is rotatably mounted inside the mounting housing 9. A hand handle 11 is fixedly mounted on the front side of the worm gear 10. A worm wheel 12 is meshed on the surface of the hand handle 11. An internally threaded tube 13 is fixedly mounted inside the worm wheel 12. The internally threaded tube 13 is rotatably mounted inside the rectangular plate 8. A screw 14 is threaded inside the internally threaded tube 13. A guide sleeve 15 is slidably mounted on the surface of the screw 14. The guide sleeve 15 is fixedly mounted on the upper side wall of the mounting housing 9. The bottom end of the screw 14 is fixed. A fixed plate 16 is fixedly installed on the top of the upper clamping plate 17. The hand handle 11 drives the worm gear 12 to rotate through the worm 10, so that the internal thread tube 13 drives the screw 14 to move downward. The screw 14 is guided by the guide sleeve 15, so that the screw 14 drives the upper clamping plate 17 to contact the refrigerated tray through the fixed plate 16. Mounting plates 24 are fixedly installed on both the front and rear sides of the mounting base 1. The top of the mounting plate 24 is provided with a mounting hole 25. The mounting plate 24 and the mounting hole 25 can fix the mounting base 1 to the equipment that cooperates with it.

[0018] Specifically, the auxiliary components include a mounting groove 18 formed at the bottom of the side clamping plate 7 and a limiting plate 20 fixedly mounted at the bottom of the side clamping plate 7. A ball bearing 19 is overlapped inside the mounting groove 18, and a limiting groove 21 is formed through the surface of the limiting plate 20. The inner wall of the limiting groove 21 overlaps with the surface of the ball bearing 19. When the side clamping plate 7 moves, the side clamping plate 7 will drive the ball bearing 19 and the limiting plate 20 to move, so that the ball bearing 19 rolls on the top of the mounting base 1, so that the ball bearing 19 supports the side clamping plate 7, thereby making the movement of the side clamping plate 7 more stable. This can prevent the bottom of the side clamping plate 7 from being suspended, or prevent the sliding friction between the side clamping plate 7 and the mounting base 1, thus making the movement of the side clamping plate 7 smoother.

[0019] Specifically, a protective pad 22 is fixedly installed on the side of the side clamp 7 near the middle of the mounting base 1. The protective pad 22 has a rectangular structure and is made of rubber. The protective pad 22 can protect the contact area between the refrigerated tray and the side clamp 7, and prevent damage to the contact area between the refrigerated tray and the side clamp 7.

[0020] Specifically, a protective pad 23 is fixedly installed at the bottom of the upper clamping plate 17. The protective pad 23 has a rectangular structure and is made of rubber. The protective pad 23 can protect the contact position between the refrigerated pallet and the upper clamping plate 17, preventing the upper clamping plate 17 from damaging the surface of the refrigerated pallet.

[0021] In use: According to the specifications of the refrigerated tray, rotate the plum blossom knob 6 to separate it from the adjusting column 4. Pull the side clamp 7 to move the adjusting column 4 inside the rectangular frame 3, so that the side clamp 7 contacts the refrigerated tray. Then, rotate the plum blossom knob 6 in the opposite direction to make it contact the adjusting column 4 and press it against the adjusting column 4, so that the plum blossom knob 6 fixes the adjusting column 4 inside the rectangular frame 3. Then, rotate the hand handle 11 to drive the worm gear 10 to rotate. The worm gear 10 drives the worm wheel 12, which in turn drives the internal thread tube 13 to rotate inside the rectangular plate 8. The internal thread tube 13 drives the screw 14 to move downward. The guide sleeve 15 guides the screw 14, which in turn drives the fixing plate 16 to move. The fixing plate 16 then drives the upper clamp 17 to move downward, so that the upper clamp 17 contacts the refrigerated tray, thus positioning the refrigerated tray.
