Description

Technical Field

[0001] This utility model relates to the field of hot welding technology for plastic sheets, specifically a fixing fixture for a plastic pallet welding machine. Background Technology

[0002] The large pallet automatic welding machine adopts the principle of pull-out hot plate welding, using a temperature-controlled heating plate to weld plastic parts. This process requires precise positioning and stable fixation of the plastic parts to be welded to ensure welding quality.

[0003] During heating and welding, the plastic pallet is fixed by a clamp. However, the clamp usually restricts the plastic pallet at the edges, which makes it difficult to heat and weld the fixed edges during welding. Furthermore, it is not convenient to adjust later because the edges are completely covered, and more steps are required for adjustment. Based on this, this application provides a fixing clamp for a plastic pallet welding machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixing fixture for a plastic pallet welding machine. This solves the problem that existing fixtures typically use edge-limiting fixing methods for plastic pallets, which makes it difficult to heat and weld the fixed edges during welding, and also results in inconvenient and complicated adjustments, affecting production efficiency and welding quality.

[0005] The present invention relates to a fixing fixture for a plastic pallet welding machine, comprising a support base for support and a fixture disposed on the support base, as well as a plastic plate adapted to the fixture.

[0006] The fixture includes a support plate, a mounting plate on the top of the support plate, symmetrically arranged positioning plates on both sides of the top of the mounting plate, two sets of symmetrically arranged support frames on the top of the positioning plates, and a support block 1 installed on the support frame. The support block 1 is adapted to the plastic plate and is used to position the plastic plate.

[0007] One side of the support block is provided with a support block, and the second support block is adapted to the bottom of the plastic plate.

[0008] As a further improvement of this utility model, the support block has a bent portion at a preset angle on one side near the edge of the mounting plate, and the bent portion abuts against the edge of the plastic plate.

[0009] As a further improvement of this utility model, the mounting plate is provided with edge blocks that are adapted to the edge of the plastic plate at its four edges. The edge blocks are arranged in an "L" shape, and the two arms of the edge blocks are adapted to the edge of the plastic plate respectively.

[0010] As a further improvement of this utility model, one or more sets of fixing seats are provided at the top center of the mounting plate, and a set of symmetrically arranged curved plates are installed on the fixing seats.

[0011] As a further improvement of this utility model, each set of the bending plates has at least two, and the two symmetrically arranged bending plates have a bending part with a preset angle on the side away from each other, which is adapted to the outer side of the plastic plate.

[0012] As a further improvement of this utility model, a second curved plate is symmetrically arranged on the top of the mounting plate between the two sets of support frames. One side of the second curved plate is vertically arranged, and the other side is bent toward one side of the support block.

[0013] As a further improvement of this utility model, an adjustment block is provided at the top of the mounting plate between the two curved plates, and the bottom of the adjustment block is inserted and adapted to the top of the mounting plate.

[0014] As a further improvement of this utility model, the support base includes a base body, and the top of the base body is located at a fixed distance from the bottom of the support plate. A movable component is provided at this fixed distance to control the movement of the support plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model uses a clamp with multiple components such as the bent part of support block one, edge stop block, bending plate one, bending plate two, and adjustment block to position and support the plastic plate from multiple positions and angles, including the edge, outer side, side, and middle. This effectively avoids displacement and shaking of the plastic plate caused by thermal stress, external impact, and other factors during the welding process, ensuring the positional stability of the plastic plate during the welding process, thereby improving the accuracy of the welding position and enhancing the welding quality.

[0017] Unlike existing edge-limiting fixing methods, this fixture does not rely solely on edge wrapping for fixation. Instead, it employs multi-part collaborative positioning and support, allowing each part of the plastic sheet to easily contact the heating plate during welding. This solves the problem of difficult heating and welding at the edges, ensuring the welding effect of the plastic sheet edges. Since the edges of the plastic sheet are not completely wrapped, and adjustable blocks and moving components that can control the movement of the support plate are provided, it is more convenient and faster to adjust the position of the plastic sheet later, reducing adjustment steps and improving production efficiency.

[0018] Furthermore, the adjusting block can be positioned on the mounting plate according to the size and shape of different plastic sheets, and the moving component can control the movement of the support plate to adapt to the welding requirements of plastic sheets of different specifications, so that the fixture can be applied to a variety of plastic sheets of different sizes and shapes, enhancing the versatility and applicability of the fixture.

[0028] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0029] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0030] Please see Figure 1 , Figure 2 as well as Figure 3 In the process of welding plastic parts using the hot plate welding principle of a large pallet automatic welding machine, precise positioning and stable fixing of the plastic parts to be welded are crucial to ensuring welding quality, and this task is undertaken by the fixing fixture 2. However, existing general fixtures 2 use edge restriction when fixing plastic pallets. This method has obvious drawbacks. During the heating and welding process, the edge of the pallet fixed by the fixture 2 is difficult to fully contact the heating plate for effective heating due to the influence of the fixture 2, resulting in poor welding effect. At the same time, since the edge is completely covered by the fixture 2, when subsequent adjustments to the position of the plastic pallet are needed, the operation steps are cumbersome and inconvenient, which will affect the overall production efficiency and further improvement of welding quality. Based on this, this application provides a fixing fixture 2 for a plastic pallet welding machine, including a support base 1 for support, a fixture 2 set on the support base 1, and a plastic plate 3 adapted to the fixture 2;

[0031] The clamp 2 includes a support plate 24, a mounting plate 210 is provided on the top of the support plate 24, and symmetrically arranged positioning plates 28 are provided on both sides of the top of the mounting plate 210. Two sets of symmetrically arranged support frames 27 are installed on the top of the positioning plates 28. Support blocks 22 are installed on the support frames 27. The support blocks 22 are adapted to the plastic plate 3 and are used to position the plastic plate 3.

[0032] A support block is provided on one side of support block 22, and support block 23 is adapted to the bottom of plastic plate 3.

[0033] The support base 1 provides a stable support foundation for the entire fixture 2. A support plate 24 is provided on the support base 1, which serves as a transition connecting the support base 1 and the mounting plate 210, ensuring the stability of the entire fixture 2 structure. The mounting plate 210 is located on top of the support plate 24, providing an installation platform for subsequent installation of components such as the positioning plate 28.

[0034] Symmetrical positioning plates 28 are provided on both sides of the top of the mounting plate 210. These two positioning plates 28 cooperate with each other to initially limit the position of the plastic plate 3 from both sides, ensuring that the plastic plate 3 is in a proper position in the horizontal direction and preventing it from shifting to the left or right, thus laying the foundation for subsequent precise positioning and welding operations.

[0035] Two sets of symmetrically arranged support frames 27 are installed on the top of the positioning plate 28. Each set of support frames 27 is equipped with a support block 22, the shape and size of which are adapted to the plastic plate 3. When the plastic plate 3 is placed on the clamp 2, the support block 22 can contact a specific part of the plastic plate 3, further positioning the plastic plate 3 from the side, ensuring that the plastic plate 3 is accurately positioned in the direction perpendicular to the positioning plate 28, and preventing it from moving back and forth. Through the combined action of the positioning plate 28 and the support block 22, the two-dimensional positioning of the plastic plate 3 on the horizontal plane is achieved.

[0036] A second support block 23 is provided on one side of the first support block 22. The top surface shape of the second support block 23 is adapted to the bottom shape of the plastic plate 3. When the plastic plate 3 is placed on the clamp 2, the second support block 23 can support the bottom of the plastic plate 3, keeping the plastic plate 3 in a horizontal state and preventing it from tilting or deforming due to its own weight or other external forces. At the same time, the second support block 23 cooperates with the first support block 22 and the positioning plate 28 to position and support the plastic plate 3 from multiple directions, ensuring the stability of the plastic plate 3 during the welding process.

[0037] Compared to clamps 2 with typical edge-limiting fixing methods, the fixing clamp 2 in this embodiment achieves more reasonable positioning and support for the plastic plate 3 through the coordinated action of the support plate 24, mounting plate 210, positioning plate 28, support frame 27, support block one 22, and support block two 23. It does not rely solely on edge restriction but fixes the plastic plate 3 from multiple angles and positions, allowing all parts of the plastic plate 3 to easily contact the heating plate during welding, thus solving the problem of difficult heating and welding at the edges. Furthermore, since the edges of the plastic plate 3 are not completely wrapped, subsequent adjustments to its position are more convenient and faster, reducing adjustment steps and improving production efficiency and welding quality. Through reasonable structural design, it effectively solves the problems existing in the prior art, providing a more reliable fixing solution for welding plastic pallets.

[0038] Please see Figure 2 , Figure 3 as well as Figure 4 The support block 22 has a bent part at a preset angle on one side near the edge of the mounting plate 210, and the bent part abuts against the edge of the plastic plate 3.

[0039] The mounting plate 210 has edge blocks 21 that are adapted to the edge of the plastic plate 3 at its four edges. The edge blocks 21 are L-shaped and the two arms of the edge blocks 21 are adapted to the edge of the plastic plate 3.

[0040] The top of the mounting plate 210 is provided with one or more sets of fixing seats 211 at the middle position, and a set of symmetrically arranged curved plates 25 are installed on the fixing seats 211.

[0041] The support block 22 has a bent portion at a preset angle on one side near the edge of the mounting plate 210. The bent portion can abut against the edge of the plastic plate 3. Its function is to provide additional positioning and support for the plastic plate 3 from the side. When the plastic plate 3 is placed on the clamp 2, the bent portion is in close contact with the edge of the plastic plate 3, preventing the plastic plate 3 from moving laterally in the horizontal direction. For example, during the welding process, the plastic plate 3 may tend to shift to one side due to the thermal stress generated by heating or the slight vibration of the welding equipment. The bent portion can effectively resist this tendency, ensuring the positional stability of the plastic plate 3 during the welding process, thereby improving the welding accuracy.

[0042] Edge blocks 21, adapted to the edges of the plastic sheet 3, are provided around the perimeter of the mounting plate 210. These edge blocks 21 are L-shaped, with two arms that fit the edges of the plastic sheet 3. The L-shaped design allows the edge blocks 21 to limit the edges of the plastic sheet 3 from two directions. One arm prevents the plastic sheet 3 from moving outwards from the mounting plate 210, while the other arm prevents the plastic sheet 3 from warping in a direction perpendicular to the plane of the mounting plate 210. In actual welding, the plastic sheet 3 may deform due to uneven heating, etc. The edge blocks 21 limit the range of this deformation, ensuring the plastic sheet 3 remains in a suitable welding position. Furthermore, the edge blocks 21 cooperate with the bent portion to position and fix the edges of the plastic sheet 3 from multiple angles, further enhancing the fixing effect.

[0043] One or more sets of fixing seats 211 are provided at the top center of the mounting plate 210. A set of symmetrically arranged curved plates 25 are installed on the fixing seats 211. The fixing seats 211 serve to connect the mounting plate 210 and the curved plates 25, ensuring that the curved plates 25 can be stably installed on the mounting plate 210. The symmetrically arranged curved plates 25 can fix and support the plastic plate 3 from the center. When the plastic plate 3 is placed on the clamp 2, the curved plates 25 contact the center of the plastic plate 3. The degree of curvature of the curved plates 25 is designed according to the shape and size of the plastic plate 3 to conform to the surface of the plastic plate 3 and provide uniform support. During the welding process, the center of the plastic plate 3 may dent or deform due to lack of support. The presence of the curved plates 25 can effectively avoid this situation, ensure the overall flatness of the plastic plate 3, and thus improve the welding quality. Moreover, the arrangement of multiple sets of fixing seats 211 and curved plates 25 can be flexibly adjusted according to different specifications of plastic plates 3 to adapt to different welding requirements.

[0044] Through the coordinated action of the bent portion of support block 22, the edge stop 21 of mounting plate 210, the fixing seat 211 in the middle of mounting plate 210, and the bending plate 25, the plastic plate 3 is positioned and supported from multiple positions at the edge and center, overcoming the drawbacks of existing general clamps that rely solely on edge constraints. This ensures the stability and positional accuracy of the plastic plate 3 during welding, avoids the problem of difficult heating and welding at the edges, and facilitates subsequent adjustments to the position of the plastic plate 3, thereby improving welding efficiency and quality.

[0045] Please see Figure 3 , Figure 4 as well as Figure 5 Each set of bending plates 25 has at least two bending sections. The two bending plates, which are symmetrically arranged, have a bending section with a preset angle on the side that is far away from each other, and are adapted to the outer side of the plastic plate 3.

[0046] The top of the mounting plate 210 is provided with a symmetrically arranged curved plate 26 between the two sets of support frames 27. One side of the curved plate 26 is vertical, and the other side is bent toward one side of the support block.

[0047] An adjusting block 29 is provided at the top of the mounting plate 210 between the two curved plates 26, and the bottom of the adjusting block 29 is inserted and adapted to the top of the mounting plate 210.

[0048] The support base 1 includes a base body 11, with a fixed gap between the top of the base body 11 and the bottom of the support plate 24. A movable component 12 is provided at this fixed gap to control the movement of the support plate 24.

[0049] Each set of bending plates 25 has at least two members. The two symmetrically arranged bending plates 25 have a curved portion at a preset angle on their opposite sides, and this curved portion is adapted to the outer side of the plastic plate 3. The preset angle is determined based on the actual shape and size of the plastic plate 3. When the plastic plate 3 is placed on the clamp 2, the curved portion of the bending plate 25 can tightly fit the outer side of the plastic plate 3. During the welding process, the plastic plate 3 may experience horizontal displacement due to thermal stress generated by heating and external forces from the welding operation. The curved portion of the bending plate 25 can provide stable support and limiting effect from the outer side of the plastic plate 3, preventing the plastic plate 3 from swaying left and right, and further improving the horizontal positioning accuracy of the plastic plate 3. For example, if the plastic plate 3 sways when the welding machine is welding it, it will lead to inaccurate welding position and affect the welding quality. The bending plate 25 effectively avoids this situation.

[0050] A symmetrically arranged curved plate 26 is positioned at the top of the mounting plate 210, between the two sets of support frames 27. One side of the curved plate 26 is vertical, while the other side bends towards the support block. The vertical side can limit the movement of the plastic plate 3 in the vertical direction, preventing excessive movement of the plastic plate 3 in the direction perpendicular to the plane of the mounting plate 210. The part bent towards the support block 22 can contact the side of the plastic plate 3, providing lateral support and positioning. During welding, the plastic plate 3 may shift to the side due to thermal expansion or the impact force during welding. The curved plate 26 can promptly prevent this shift, ensuring the stability of the plastic plate 3 during welding. Furthermore, the curved plate 26 works in conjunction with the curved plate 25 to fix and support the plastic plate 3 from different angles and positions, enhancing the overall fixation effect.

[0051] An adjusting block 29 is located at the top of the mounting plate 210, between the two curved plates 26. The bottom of the adjusting block 29 is inserted into the top of the mounting plate 210. This insertion and fitting method allows the adjusting block 29 to be adjusted in position on the mounting plate 210 as needed. When welding plastic plates 3 of different sizes and shapes, it may be necessary to fine-tune the fixing position and support force of the plastic plate 3. By moving the position of the adjusting block 29, its support point and support force on the plastic plate 3 can be changed, thereby achieving flexible adjustment of the fixing state of the plastic plate 3. For example, when the size of the plastic plate 3 is slightly larger or smaller, moving the adjusting block 29 can make it better contact the plastic plate 3, provide appropriate support, and ensure welding quality.

[0052] The support base 1 includes a base body 11, with a fixed gap between the top of the base body 11 and the bottom of the support plate 24. A moving component 12 is provided at this fixed gap to control the movement of the support plate 24. The moving component 12 can be a transmission mechanism consisting of a motor, lead screw, slider, etc., or other mechanisms capable of linear movement. When welding plastic plates 3 of different specifications, it may be necessary to adjust the position of the support plate 24 to ensure that the plastic plate 3 is in the optimal welding position. By controlling the movement of the support plate 24 through the moving component 12, the position of the plastic plate 3 relative to the welding equipment can be easily changed, improving the flexibility and accuracy of welding. For example, for some larger plastic plates 3, it may be necessary to move the support plate 24 to a more suitable position so that the welding equipment can better cover the welding area, thereby improving welding efficiency and quality.

[0053] By incorporating the bending plate 25, the bending plate 26, the adjusting block 29, and the moving assembly 12 of the support base 1, this fixing clamp 2 further optimizes the fixing and positioning method of the plastic plate 3. It supports and limits the plastic plate 3 from multiple positions and angles, and can be flexibly adjusted according to the needs of different plastic plates 3. This overcomes the shortcomings of existing general clamps 2, improves the quality and efficiency of plastic pallet welding, and also enhances the versatility and applicability of the clamp 2.

[0054] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
