Description

Technical Field

[0001] This utility model relates to the field of pneumatic fixture technology, specifically a multi-workpiece clamping pneumatic fixture. Background Technology

[0002] In the current wire harness processing industry, especially when performing operations such as wire harness cutting, the clamping process is crucial.

[0003] Traditional wire harness cutting typically involves manually pulling the wire harness and securing it with simple clamps. However, the manually applied clamping force is difficult to maintain consistently and evenly, leading to swaying or displacement of the wire harness during cutting, resulting in inaccurate dimensions and a lower product yield. Furthermore, operators must maintain a constant state of tension on the wire harness for extended periods, resulting in extreme labor intensity and fatigue, further impacting clamping stability and cutting quality. Therefore, a multi-workpiece clamping pneumatic fixture is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a pneumatic fixture for clamping multiple workpieces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-workpiece clamping pneumatic fixture, including an operating table, a support frame fixed to the top of the operating table, a cylinder fixed to the top of the support frame, a pressure plate fixed to the cylinder push rod end, and the pressure plate being used to clamp the workpiece;

[0006] The top of the operating table is provided with several horizontal plates, and the top of the horizontal plates is provided with several positioning slots, which are used to place workpieces.

[0007] An adjustment component is provided on one side of the horizontal plate;

[0008] The adjustment assembly includes a first rotating shaft and a connecting plate. A fixing frame is fixedly sleeved on the outside of the first rotating shaft, and a plurality of limiting holes are opened on the outside of the first rotating shaft.

[0009] A screw is threaded to one side of the connecting plate, a turntable is fixed to the top of the screw, and a bolt is threaded to one side of the turntable.

[0010] Preferably, as described above, a rubber pad is fixed to the bottom of the pressure plate, and the rubber pad is located at the top of the horizontal plate;

[0011] A guide rod is fixed to the top of the pressure plate, and a limit block is fixed to the top of the guide rod. The outer side of the guide rod is slidably connected to one side of the support frame through a linear bearing.

[0012] Preferably, the cross-section of the fixing frame is hexagonal, and the bottom of the bolt abuts against the top of the connecting plate.

[0013] Preferably, as described above, a connecting rod is fixed at the center of the first rotating shaft, and a handwheel is fixed at one end of the connecting rod.

[0014] Preferably, when the screw is inserted into the inner side of the limiting hole, the fixing frame is in a positioning state, and when the screw leaves the inner side of the limiting hole, the fixing frame is in a rotating state.

[0015] Preferably, the operating table has an insertion slot inside, and a cover plate located below the insertion slot is connected to the bottom of the operating table by screws.

[0016] Preferably, the surface of the horizontal plate is provided with screw holes, and the inner side of the screw holes is connected to the outer side of the fixing frame by screws.

[0017] Preferably, the outer side of the first rotating shaft is rotatably connected to the inner side of the insertion slot via a bearing, and one side of the connecting plate is fixed to one side of the operating table.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0019] 1. By controlling the cylinder to start, the pressure plate moves downward and cooperates with the horizontal plate to clamp multiple wire harnesses placed in the positioning slot. This provides a stable and uniform clamping force, avoiding the need for manual pulling of the wire harnesses during cutting, reducing the labor intensity of operators, and improving production efficiency.

[0020] 2. When it is necessary to adjust the position of the horizontal plate, the limit of the turntable is released by turning the bolt, and then the screw is moved away from the limit hole by the turntable, so that the fixed frame and the first rotating shaft can be rotated. Then, the angle can be easily adjusted by turning the handwheel. The whole process is clear and easy to learn, and the adjustment work can be completed quickly, saving time and manpower.

[0021] Third, opening the cover plate makes it easy to inspect and maintain the horizontal plate, reducing the difficulty of maintenance.

[0031] Example

[0032] Please see Figure 1-5This utility model provides a technical solution: a multi-workpiece clamping pneumatic fixture, including an operating table 1, a cutting mechanism (not shown in the figure) on one side of the operating table 1, a support frame 6 fixed to the top of the operating table 1, a cylinder 9 fixed to the top of the support frame 6, and a pressure plate 5 fixed to the push rod end of the cylinder 9 for clamping the workpieces; the top of the operating table 1 is provided with several horizontal plates 3, and the top of the horizontal plates 3 is provided with several positioning grooves. The size of the positioning grooves on the top of each horizontal plate 3 is different, so the top of each horizontal plate 3 can accommodate wire harnesses of different diameters. The positioning grooves are used to place the workpieces. The operator selects the corresponding size positioning groove on the top of the horizontal plate 3 according to the diameter of the wire harness, and clamps multiple wire harnesses. The wire harness is placed horizontally inside the positioning groove, ensuring that the wire harness axis coincides with the positioning groove axis. The workpiece can be a wire harness. When cutting the wire harness, multiple wire harnesses are placed inside the positioning groove. Then, the push rod end of the control cylinder 9 extends, and the push rod end drives the pressure plate 5 and rubber pad 4 to move downward. With the cooperation of the pressure plate 5 and the horizontal plate 3, multiple wire harnesses are clamped. The push rod end of the control cylinder 9 extends downward, and the push rod pushes the pressure plate 5 and the bottom rubber pad 4 to press down vertically. The rubber pad 4 and the top of the horizontal plate 3 form a flexible contact surface. Multiple wire harnesses are clamped and fixed synchronously by the pressure of the cylinder 9. The air inlet and outlet of the cylinder 9 are connected to the solenoid valve respectively. At the same time, the air source of the cylinder 9 is provided by the air compressor.

[0033] A rubber pad 4 is fixed to the bottom of the pressure plate 5, and the rubber pad 4 is located at the top of the horizontal plate 3; a guide rod 7 is fixed to the top of the pressure plate 5, and a limit block 8 is fixed to the top of the guide rod 7; the outer side of the guide rod 7 is slidably connected to one side of the support frame 6 through a linear bearing.

[0034] An adjustment assembly 2 is provided on one side of the horizontal plate 3. The adjustment assembly 2 includes a first rotating shaft 21 and a connecting plate 24. Both the first rotating shaft 21 and the connecting plate 24 are made of metal. A fixing bracket 210 is fixedly sleeved on the outside of the first rotating shaft 21. Several limiting holes 22 are opened on the outside of the first rotating shaft 21. The limiting holes 22 and the screw 23 are H7 / g6 clearance fit. The screw 23 is threadedly connected to one side of the connecting plate 24. A turntable is fixed to the top of the screw 23. A bolt 26 is threadedly connected to one side of the turntable. The limiting holes 22 are located on one side of the horizontal plate 3. The limiting holes 22 are equidistantly distributed around the first rotating shaft 21, and the included angle between adjacent holes is 60°.

[0035] The cross-section of the fixing frame 210 is hexagonal. The bottom of the bolt 26 abuts against the top of the connecting plate 24. A connecting rod 28 is fixed at the axis of the first rotating shaft 21. A handwheel 27 is fixed at one end of the connecting rod 28. When it is necessary to adjust the position of different horizontal plates 3 under the pressure plate 5, first rotate the turntable to drive the screw 23 to move upward, so that the bottom of the screw 23 disengages from the limiting hole 22 on the outside of the first rotating shaft 21. At this time, the fixing frame 210 releases the rotation limit.

[0036] When the screw 23 is inserted into the inner side of the limiting hole 22, the fixing bracket 210 is in the positioning state. When the screw 23 leaves the inner side of the limiting hole 22, the fixing bracket 210 is in the rotating state. After the adjustment is completed, the turntable is rotated in the opposite direction to make the screw 23 re-insert into the corresponding limiting hole 22. The bottom of the bolt 26 abuts against the top of the connecting plate 24 to form a secondary locking, ensuring that the angle of the first rotating shaft 21 and the horizontal plate 3 is fixed.

[0037] The operating table 1 has an insertion slot 29 inside. The bottom of the operating table 1 is connected to a cover plate 10 located below the insertion slot 29 by screws. When it is necessary to replace the horizontal plate 3 of different specifications, the connecting screws of the screw holes 11 on the surface of the horizontal plate 3 are removed, and the new horizontal plate 3 is re-fixed to the outside of the fixing frame 210 through the screw holes 11. The horizontal plate 3 has screw holes 11 on its surface. The inside of the screw holes 11 is connected to the outside of the fixing frame 210 by screws. The outside of the first rotating shaft 21 is rotatably connected to the inside of the insertion slot 29 through a bearing. One side of the connecting plate 24 is fixed to one side of the operating table 1.

[0038] Working principle: Based on the diameter of the wire harness to be clamped, select a horizontal plate 3 with a positioning groove of appropriate size. Since the positioning groove size at the top of each horizontal plate 3 is different, it can accommodate wire harnesses of different diameters. Place multiple wire harnesses in sequence inside the positioning groove at the top of the selected horizontal plate 3 to complete the initial positioning of the workpiece.

[0039] When the control cylinder 9 is activated, the push rod end of the cylinder 9 extends. The push rod end of the cylinder 9 is fixed with a pressure plate 5, so when the push rod end extends, it will drive the pressure plate 5 to move downward. A rubber pad 4 is fixed at the bottom of the pressure plate 5, and the rubber pad 4 also moves downward with the pressure plate 5. A guide rod 7 is fixed at the top of the pressure plate 5, and a limit block 8 is fixed at the top of the guide rod 7. The outer side of the guide rod 7 is slidably connected to one side of the support frame 6 through a linear bearing. During the downward movement of the pressure plate 5, the guide rod 7 slides in the linear bearing, which plays a guiding role and ensures that the pressure plate 5 moves vertically downward, preventing the pressure plate 5 from deviating during the movement. When the pressure plate 5 moves downward to cooperate with the horizontal plate 3, the rubber pad 4 is located at the top of the horizontal plate 3. Under the joint action of the pressure plate 5 and the horizontal plate 3, multiple wire harnesses placed in the positioning groove are clamped. The rubber pad 4 can play a role in buffering and protecting the wire harnesses, preventing the pressure plate 5 from directly crushing the wire harnesses. With the power of the cylinder 9, the wire harnesses do not need to be manually pulled during cutting.

[0040] When it is necessary to adjust the angle of the horizontal plate 3, first rotate bolt 26 so that the bottom of bolt 26 moves away from the top of connecting plate 24, releasing the bolt 26 from limiting the turntable. Then rotate the turntable so that screw 23 rotates upward until screw 23 moves away from the inner side of the limiting hole 22 opened on the outer side of the first rotating shaft 21. At this time, the fixing bracket 210 is in a rotatable state. Because the fixing bracket 210 is fixedly sleeved on the outer side of the first rotating shaft 21, the first rotating shaft 21 can also rotate.

[0041] By rotating the handwheel 27, the connecting rod 28 is driven to rotate, which in turn drives the first rotating shaft 21 to rotate. Since the fixing frame 210 is fixed on the first rotating shaft 21, and the surface of the horizontal plate 3 is provided with screw holes 11, the inner side of the screw holes 11 is connected to the outer side of the fixing frame 210 by screws. Therefore, the rotation of the first rotating shaft 21 will drive the fixing frame 210 and the horizontal plate 3 to rotate together, thereby realizing the adjustment of the angle of the horizontal plate 3.

[0042] Once the horizontal plate 3 is adjusted to the appropriate position, stop rotating the handwheel 27, causing the first rotating shaft 21 to drive the fixed frame 210 to rotate. At this time, the limiting hole 22 at the top is aligned with the screw 23. Rotate the turntable in the opposite direction, causing the screw 23 to rotate downward and insert into the inner side of the corresponding limiting hole 22. At this time, the fixed frame 210 is in a positioning state and can no longer rotate, thus fixing the position of the horizontal plate 3. Finally, rotate the bolt 26 so that the bottom of the bolt 26 abuts against the top of the connecting plate 24, limiting the turntable and preventing the screw 23 from loosening and leaving the limiting hole 22 during equipment operation.

[0043] The bottom of the operating table 1 is connected to a cover plate 10 located below the insertion slot 29 by screws. Opening the cover plate 10 makes it easy to inspect and repair the horizontal plate 3. When it is necessary to replace or repair the horizontal plate 3, unscrew the screws connecting the horizontal plate 3 and the fixing frame 210 to remove the horizontal plate 3 from the fixing frame 210.

[0044] After the single batch of wire harness cutting is completed, the cylinder 9 push rod retracts, the pressure plate 5 is reset under the guidance of the guide rod 7, the processed wire harness is taken out, and the steps are repeated for the next round of clamping operation.

[0045] In summary, by controlling the start of cylinder 9, the pressure plate 5 moves downward and cooperates with the horizontal plate 3 to clamp multiple wire harnesses placed in the positioning slot. This provides a stable and uniform clamping force, avoids the need for manual pulling of the wire harnesses during cutting, reduces the labor intensity of operators, and improves production efficiency.

[0046] When the position of the horizontal plate 3 needs to be adjusted, the limit on the turntable is released by rotating the bolt 26, and then the screw 23 is moved away from the limit hole 22 by the turntable, so that the fixing frame 210 and the first rotating shaft 21 can be rotated. Subsequently, the horizontal plate 3 can be easily rotated by rotating the handwheel 27 to adjust the angle. The whole process is clear and easy to learn, and the adjustment work can be completed quickly, saving time and manpower.

[0047] By opening the cover plate 10, the horizontal plate 3 can be easily inspected and repaired, reducing the difficulty of inspection. By unscrewing the screws connecting the horizontal plate 3 and the fixing bracket 210, the horizontal plate 3 can be removed from the fixing bracket 210, making the replacement and maintenance of the horizontal plate 3 more convenient and reducing maintenance time and cost.
