Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding and fixing technology, and in particular to tooling for welding and fixing thermoplastic products. Background Technology
[0002] Welding is a common method for joining thermoplastic products. Thermoplastics soften or melt when heated and then solidify again upon cooling. Welding utilizes this property: heating the plastic parts to melt the connecting areas, applying pressure to fuse them together, and then allowing them to cool and form a strong, unified whole.
[0003] Currently, when two products need to be welded together, a hand-held welding torch is used to melt the ribs of one product and then adhere it to the other. During welding, the hand must remain stationary while pressing down, and the product can only be welded after cooling. This process, due to the prolonged downward pressure, makes it difficult to maintain a perfectly vertical orientation, easily leading to misalignment at the joint and a low yield rate. To address this issue, a fixture for welding and fixing thermoplastic products is provided. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a tooling for welding and fixing thermoplastic products, comprising:
[0005] A tooling table, wherein at least one pair of concave platforms are fixedly provided on the tooling table;
[0006] A movable mechanism fixedly mounted on a tooling table includes a long box and a right-angle support rod. The long box is fixedly mounted on the tooling table. A first threaded rod is rotatably mounted inside the long box. One end of the right-angle support rod is slidably connected to the long box. The first threaded rod is threadedly connected to the right-angle support rod. A movable groove is formed inside the right-angle support rod. A movable block is slidably mounted inside the movable groove. A second threaded rod is rotatably mounted inside the movable groove. The second threaded rod is threadedly connected to the movable block. An electric actuator is fixedly mounted at the bottom of the movable block.
[0007] A clamping mechanism is fixedly installed at the end of the piston rod of an electric actuator. The clamping mechanism includes a U-shaped plate, a first double-threaded rod is rotatably provided inside the U-shaped plate, and a pair of clamping plates are slidably provided inside the U-shaped plate. The first double-threaded rod is threadedly connected to the pair of clamping plates.
[0008] At least one set of fixing mechanisms is fixedly installed on the tooling table, and the fixing mechanisms are located between the concave tables.
[0009] As an improvement to the above technical solution, the fixing mechanism includes a box, a pair of uprights and a pair of movable rods. The box is fixedly mounted on a tooling table. A second double-threaded rod is provided axially inside the box. The uprights are all slidably connected inside the box. The second double-threaded rod is threadedly connected to the pair of uprights. One end of each movable rod is slidably connected inside the upright.
[0010] As an improvement to the above technical solution, each of the movable rods is fixedly provided with an elastic element at the same end, the other end of the elastic element is fixedly connected to the inner wall of the upright, and the other end of the movable rod is rotatably provided with a pressure plate.
[0011] As an improvement to the above technical solution, at least one connecting frame is fixedly provided on the rear side of the U-shaped plate, and a cooling fan is fixedly provided at the bottom of the connecting frame.
[0012] As an improvement to the above technical solution, the right-angle support rod is set vertically on the long box, the moving groove is parallel to the upper surface of the tooling table, a pair of clamping plates are symmetrically arranged on the first double-headed threaded rod, and anti-slip strips are fixed on the opposite side of the pair of clamping plates.

[0014] As an improvement to the above technical solution, a knob is also fixedly provided at one end of the second double-ended threaded rod, and the upright is symmetrically arranged on the second double-ended threaded rod.
[0015] The beneficial effects of this utility model are:
[0016] By using a concave platform, a long box, a first threaded rod, a right-angle support rod, a moving groove, a moving block, a second threaded rod, an electric push rod, and a clamping mechanism, two workpieces to be fused are placed. One workpiece is placed on the concave platform, and the other is clamped and fixed by the clamping mechanism. The position of the clamping mechanism is adjusted by the first and second threaded rods, causing the workpiece fixed on the clamping mechanism to move to the desired position. After heat melting, the electric push rod drives the workpiece to descend and fit against the other workpiece through the clamping mechanism, waiting for it to cool and solidify. The downward pressure of the electric push rod can be ensured to be vertically downward, thereby reducing the occurrence of misalignment in the fixed position and improving the yield of the connected products.

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0024] Currently, when two products need to be welded together, the welding torch is used to melt the ribs of one product and then adhere it to the other. During welding, the hand must remain stationary while pressing down, and the product can only be welded after cooling. This process, due to the prolonged downward pressure, makes it difficult to maintain a perfectly vertical orientation, easily leading to misalignment at the joint and resulting in a low yield rate.
[0025] To resolve this issue, please refer to Figure 1-5 A tooling for welding and fixing thermoplastic products includes: a tooling table 1, on which at least one pair of concave platforms 11 are fixedly provided;
[0026] A moving mechanism 2 is fixedly installed on the tooling table 1. The moving mechanism 2 includes a long box 21 and a right-angle support rod 24. The long box 21 is fixedly installed on the tooling table 1. A first threaded rod 22 is rotatably provided in the long box 21 along the axis. One end of the right-angle support rod 24 is slidably connected to the long box 21. The first threaded rod 22 is threadedly connected to the right-angle support rod 24. A moving groove 26 is opened in the right-angle support rod 24. A moving block 27 is slidably provided in the moving groove 26. A second threaded rod 28 is rotatably provided in the moving groove 26 along the axis. The second threaded rod 28 is threadedly connected to the moving block 27. An electric push rod 29 is fixedly provided at the bottom of the moving block 27.
[0027] A clamping mechanism 3 is fixedly installed at the piston rod end of the electric actuator 29. The clamping mechanism 3 includes a U-shaped plate 32, a first double-threaded rod 33 is rotatably provided inside the U-shaped plate 32, and a pair of clamping plates 34 are slidably provided inside the U-shaped plate 32. The first double-threaded rod 33 is threadedly connected to the pair of clamping plates 34.
[0028] At least one set of fixing mechanisms 4 are fixedly installed on the tooling table 1, and the fixing mechanisms 4 are located between the concave tables 11.
[0029] In use, one workpiece is placed in the groove of the concave stage 11 and fixed by the fixing mechanism 4. The other workpiece is placed with the welding surface facing down between a pair of clamping plates 34. Rotating the first double-ended threaded rod 33 causes the clamping plates 34 to move towards the center, clamping and fixing the workpiece on the clamping mechanism 3. Rotating the first threaded rod 22 causes the first threaded rod 22 to move the right-angle support rod 24 left and right through the long box 21. The right-angle support rod 24 moves the electric actuator 29 left and right through the moving block 27. The electric actuator 29 moves the workpiece left and right through the clamping mechanism 3. The second threaded rod 28 drives the moving block 27 to move back and forth via the moving groove 26. The moving block 27 drives the clamping mechanism 3 to move back and forth via the electric push rod 29. The clamping mechanism 3 drives the workpiece to move back and forth. By moving the workpiece back, forth, left, and right, the workpiece is moved to the position directly above the welding and fixing position. After the workpiece connection position is heat-melted, the electric push rod 29 is activated. The electric push rod 29 drives the workpiece downward via the clamping mechanism 3, so that the workpieces fit together. After cooling, the welding and fixing is completed. This welding method can increase the yield rate of workpiece welding.
[0030] In the specific implementation process, such as Figure 4 As shown, the fixing mechanism 4 includes a box body 41, a pair of uprights 43 and a pair of movable rods 46. The box body 41 is fixedly mounted on the tooling table 1. A second double-ended threaded rod 42 is provided inside the box body 41 and rotates axially. The uprights 43 are all slidably connected inside the box body 41. The second double-ended threaded rod 42 is threadedly connected to the pair of uprights 43. One end of the movable rod 46 is slidably connected inside the uprights 43.
[0031] In use, after placing the workpiece on the concave table 11, rotate the second double-threaded rod 42. The second double-threaded rod 42 drives the upright rod 43 to move towards the center through the box 41. The upright rod 43 drives the movable rod 46 to move towards the center. The movable rod 46 clamps the workpiece in the center of the groove of the concave table 11 and fixes it to prevent it from shifting during welding.
[0032] In the specific implementation process, such as Figure 5 As shown, each of the movable rods 46 is fixedly provided with an elastic element 45 at the same end, and the other end of the elastic element 45 is fixedly connected to the inner wall of the upright rod 43. Each of the movable rods 46 is rotatably provided with a lower pressure plate 47.
[0033] In use, before the movable rod 46 fixes the workpiece, pull the movable rod 46 upward. The movable rod 46 moves upward and stretches the elastic element 45. Rotate the lower pressure plate 47 to make the lower pressure plate 47 fit against the upper surface of the workpiece. Release the movable rod 46. The elastic element 45 pulls the movable rod 46 downward. The movable rod 46 drives the lower pressure plate 47 to press down on the workpiece. Then, the workpiece is clamped and fixed by the movable rod 46. This makes the movable rod 46 more stable when clamping and reduces the deformation of the workpiece caused by the movable rod 46 clamping it.
[0034] In the specific implementation process, such as Figure 3 As shown, at least one connecting bracket 321 is fixedly provided on the rear side of the U-shaped plate 32, and a cooling fan 322 is fixedly provided at the bottom of the connecting bracket 321.
[0035] When in use, the cooling fan 322 is activated when the workpiece is hot-melted and fixed, so as to cool down the hot-melted and fixed area and speed up the hot-melt and fixed speed of the workpiece.
[0036] In the specific implementation process, such as Figure 4 As shown, the right-angle support rod 24 is vertically arranged on the long box 21, the moving groove 26 is parallel to the upper surface of the tooling table 1, and a pair of clamping plates 34 are symmetrically arranged on the first double-headed threaded rod 33. Anti-slip strips 341 are fixed on the opposite side of the pair of clamping plates 34.
[0037] In use, the symmetrical arrangement of the clamping plates 34 ensures that the clamped workpiece is centered in the clamping mechanism 3 when it is clamped, and the anti-slip strip 341 prevents slippage when the workpiece is clamped and pressed down.
[0038] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a motor 25 is fixedly installed inside the right-angle support rod 24. The output end of the motor 25 is fixedly connected to one end of the second threaded rod 28. A handle 23 is fixedly installed at one end of the first threaded rod 22, and a knob 5 is fixedly installed at one end of the first double-headed threaded rod 33.
[0039] When in use, start the motor 25. The output end of the motor 25 drives the second threaded rod 28 to rotate. Turning the handle 23 can drive the first threaded rod 22 to rotate. Turning the knob 5 at the end of the first double-ended threaded rod 33 can drive the first double-ended threaded rod 33 to rotate. The handle 23 and the knob 5 make it easier to rotate the first threaded rod 22 and the first double-ended threaded rod 33.
[0040] In the specific implementation process, such as Figure 5 As shown, a knob 5 is also fixedly provided at one end of the second double-ended threaded rod 42, and the upright rod 43 is symmetrically arranged on the second double-ended threaded rod 42.
[0041] In use, turning the knob 5 at the end of the second double-ended threaded rod 42 can drive the second double-ended threaded rod 42 to rotate, making the rotation of the second double-ended threaded rod 42 easier. The symmetrical arrangement of the upright rod 43 can fix the workpiece in the middle of the groove when fixing the workpiece on the concave table 11.
[0042] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
