Description

Technical Field

[0001] This utility model belongs to the field of automotive exhaust hook processing technology, and in particular relates to a fixture for processing automotive exhaust hooks. Background Technology

[0002] The exhaust hook is an important component of the exhaust system. Its main function is to suspend the exhaust pipe on the vehicle body and reduce the transmission of exhaust pipe vibration to the vehicle body, thereby reducing interior noise and improving ride comfort. In the manufacturing process of the exhaust hook, the clamp is a very important tool. It helps workers to accurately position and fix the hook, ensuring that it will not move during welding and surface rust removal.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] In the current technology, the fixture is a very important tool in the processing of automotive exhaust hooks. However, the existing automotive exhaust hook fixtures can only hold the exhaust hook vertically. When horizontal clamping is required, the position will shift due to the small clamping area. Therefore, a fixture for processing automotive exhaust hooks is proposed to solve the above problems. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a clamp for processing automobile exhaust hooks, which has the advantages of clamping automobile exhaust hooks horizontally and vertically. It can overcome the above problems or at least partially solve the problem that automobile exhaust hook clamps can only clamp exhaust hooks vertically, and when horizontal clamping is required, positional movement will occur due to the small clamping area.

[0006] This utility model is implemented as follows: a jig for processing automotive exhaust hooks includes a mounting base, two clamping plates and a mounting groove. The clamping plates are movably connected to the top of the mounting base, and the mounting groove is formed in the inner cavity of the clamping plates.

[0007] The mounting base has control grooves on both the front and rear sides, and mating grooves on both the front and rear sides.

[0008] A positioning component for fixing the position of the clamping plate, the positioning component being disposed within the cavity of the mounting groove.

[0009] As a preferred embodiment of this utility model, clamping pads are fixedly connected to the opposite sides of the two clamping plates, and clamping grooves are provided on the opposite sides of the two clamping pads. The number of clamping grooves is multiple. By setting clamping pads and clamping grooves, the two clamping pads can increase the friction when the two clamping plates clamp the car exhaust hook, and the multiple clamping grooves can make the car exhaust hook clamped more stably.

[0010] As a preferred embodiment of this utility model, the top of the clamping plate is provided with matching grooves. There are four matching grooves of different sizes. By setting matching grooves, when it is necessary to fix the exhaust hook horizontally, the exhaust hook can be inserted into the matching groove. The exhaust hook can also be fixed horizontally. Moreover, the matching grooves of different sizes can clamp different models of exhaust hooks.

[0011] As a preferred embodiment of this utility model, a control block is movably connected to the inner cavity of the control groove. A pulley is fixedly installed on the side of the control block away from the clamping plate, and the side of the control block close to the clamping plate is fixedly connected to the clamping plate. By setting the control block and the pulley, the control block and the control groove can control the movement position of the clamping plate when it moves, while the pulley can reduce the friction between the control block and the mounting base.

[0012] In a preferred embodiment of this invention, the positioning component includes two pressing blocks, which are movably connected to the inner cavity of the mounting groove. Four springs are fixedly connected to opposite sides of each of the two pressing blocks, and an L-shaped rod is fixedly connected to opposite sides of each of the two pressing blocks. By setting the positioning component, when the L-shaped rod moves, the pressure of the springs on the pressing blocks prevents the pressing blocks from moving within the mounting groove, thus preventing the pressing blocks from causing the toothed plate fixed on the L-shaped rod to move erratically.

[0013] In a preferred embodiment of this invention, the L-shaped rod, on the side away from the extrusion block, passes through the mounting groove and is fixedly connected to a toothed plate. The mating groove, on the side near the toothed plate, has a toothed groove that mates with the toothed plate. The toothed plate is inserted into the inner cavity of the toothed groove, and there are multiple toothed grooves. By setting toothed plates and toothed grooves, and having multiple toothed grooves, the toothed plate can be inserted into toothed grooves at different positions, thus allowing for the clamping of automotive exhaust hooks of different widths.

[0014] In a preferred embodiment of this invention, each of the extrusion blocks has a positioning groove on one of its opposite sides. A positioning plate is movably connected to the inner cavity of the mounting groove. A rotating rod is fixedly connected to the side of the positioning plate away from the spring. The rotating rod extends through the mounting groove and outward from the side away from the positioning plate. By setting the positioning groove, the positioning plate, and the rotating rod, when it is necessary to position the extrusion block, rotating the rotating rod causes the positioning plate to rotate within the mounting groove. The rotation of the positioning plate will compress the extrusion block. When the positioning plate rotates 90 degrees and contacts the inner wall of the positioning groove, the position of the extrusion block can be positioned.

[0015] This utility model, through the combined use of an installation groove, a control groove, a mating groove, and a positioning component, allows the extrusion block to move and drive the toothed plate on the L-shaped rod to insert into the toothed groove, thus fixing the position of the clamping plate. When it is necessary to fix the exhaust hook horizontally, the exhaust hook can be inserted into the mating groove to fix the exhaust hook horizontally. This solves the problem that the car exhaust hook clamp can only clamp the exhaust hook vertically, and when it is necessary to clamp horizontally, the position will shift due to the small clamping area.

[0021] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown in the figure, the present invention provides a jig for processing automotive exhaust hooks, including a mounting base 1, two clamping plates 2 and a mounting groove 3. The clamping plates 2 are movably connected to the top of the mounting base 1, and the mounting groove 3 is opened in the inner cavity of the clamping plates 2.

[0024] The front and rear sides of the mounting base 1 are provided with control grooves 4, and the front and rear sides of the mounting base 1 are provided with mating grooves 5.

[0025] A positioning component 6 is used to fix the position of the clamping plate 2. The positioning component 6 is disposed in the inner cavity of the mounting groove 3.

[0026] refer to Figure 3Each of the two clamping plates 2 has a clamping pad 7 fixedly connected to one side of its opposite side. Each of the two clamping pads 7 has a clamping groove 8 on one side of its opposite side, and there are multiple clamping grooves 8.

[0027] The above solution is adopted: by setting clamping pads 7 and clamping grooves 8, when the two clamping plates 2 clamp the car exhaust hook, the two clamping pads 7 can increase the friction, and the multiple clamping grooves 8 can make the car exhaust hook clamped more stably.

[0028] refer to Figure 3 The top of the clamping plate 2 is provided with four matching grooves 9, which are of different sizes.

[0029] The above solution is adopted: by setting the matching groove 9, when it is necessary to fix the exhaust hook horizontally, the exhaust hook is inserted into the matching groove 9, and the exhaust hook can be fixed horizontally. Moreover, the matching groove 9 of different sizes can clamp different models of exhaust hooks.

[0030] refer to Figure 2 A control block 10 is movably connected to the inner cavity of the control groove 4. A pulley 11 is fixedly installed on the side of the control block 10 away from the clamping plate 2, and the side of the control block 10 close to the clamping plate 2 is fixedly connected to the clamping plate 2.

[0031] The above scheme is adopted: by setting control block 10 and pulley 11, when the clamping plate 2 moves, control block 10 and control groove 4 can control the movement position of clamping plate 2, while pulley 11 can reduce the friction between control block 10 and mounting base 1.

[0032] refer to Figure 4 The positioning component 6 includes two pressing blocks 61, which are movably connected to the inner cavity of the mounting groove 3. Springs 62 are fixedly connected to opposite sides of the two pressing blocks 61, and there are four springs 62. L-shaped rods 63 are fixedly connected to opposite sides of the two pressing blocks 61.

[0033] The above solution is adopted: by setting the positioning component 6, when the L-shaped rod 63 moves, the pressure of the spring 62 on the pressing block 61 will prevent the pressing block 61 from moving in the mounting groove 3, so that the pressing block 61 will not cause the toothed plate 12 fixed on the L-shaped rod 63 to move randomly.

[0034] refer to Figure 2 and Figure 3 The L-shaped rod 63, away from the extrusion block 61, passes through the mounting groove 3 and is fixedly connected to the toothed plate 12. The mating groove 5, near the toothed plate 12, has a toothed groove 13 that mates with the toothed plate 12. The toothed plate 12 is inserted into the inner cavity of the toothed groove 13, and there are multiple toothed grooves 13.

[0035] The above solution involves setting toothed plates 12 and toothed grooves 13, with multiple toothed grooves 13. This allows the toothed plates 12 to be inserted into toothed grooves 13 at different positions, thus enabling the clamping of automotive exhaust hooks of different widths.

[0036] refer to Figure 4 The extrusion block 61 has a positioning groove 14 on each side opposite to it. The inner cavity of the mounting groove 3 is movably connected to the positioning plate 15. The side of the positioning plate 15 away from the spring 62 is fixedly connected to the rotating rod 16. The side of the rotating rod 16 away from the positioning plate 15 passes through the mounting groove 3 and extends to the outside of the mounting groove 3.

[0037] The above solution is adopted: by setting the positioning groove 14, the positioning plate 15 and the rotating rod 16, when it is necessary to position the extrusion block 61, the rotating rod 16 is rotated to drive the positioning plate 15 to rotate in the mounting groove 3. The rotation of the positioning plate 15 will squeeze the extrusion block 61. After the positioning plate 15 rotates 90 degrees and contacts the inner wall of the positioning groove 14, the position of the extrusion block 61 can be positioned.

[0038] The working principle of this utility model:

[0039] In use, rotating the rotating rod 16 causes the positioning plate 15 to rotate within the mounting groove 3. The rotation of the positioning plate 15 will squeeze the pressing block 61. The pressing block 61 will squeeze the spring 62 and drive the L-shaped rod 63 to move. The movement of the L-shaped rod 63 will cause the toothed plate 12 to disengage from the toothed groove 13. After the positioning plate 15 rotates 90 degrees and contacts the inner wall of the positioning groove 14, the position of the pressing block 61 can be positioned.

[0040] Then, the exhaust hook can be placed vertically on top of the mounting base 1. Then, push the two clamping plates 2 to move. The movement of the clamping plates 2 will cause the control block 10 to move in the control groove 4. At this time, the pulley 11 can reduce the friction during movement. After the two clamping plates 2 drive the clamping pad 7 to clamp the exhaust hook, rotate the rotating rod 16 to drive the positioning plate 15 back to its original position. The spring 62 will undergo elastic deformation to drive the two pressing blocks 61 back to their original position. The movement of the pressing block 61 will drive the toothed plate 12 on the L-shaped rod 63 to insert into the toothed groove 13. At this time, the position of the clamping plate 2 can be fixed. When it is necessary to fix the exhaust hook horizontally, insert the exhaust hook into the matching groove 9. The exhaust hook can also be fixed horizontally.

[0041] In summary, this automotive exhaust hook processing fixture, through the coordinated use of the mounting groove 3, control groove 4, mating groove 5, and positioning component 6, allows the pressing block 61 to move, causing the toothed plate 12 on the L-shaped rod 63 to insert into the toothed groove 13, thus fixing the position of the clamping plate 2. When it is necessary to fix the exhaust hook horizontally, the exhaust hook can be inserted into the matching groove 9 to fix the exhaust hook horizontally. This solves the problem that the automotive exhaust hook fixture can only clamp the exhaust hook vertically, and when it needs to clamp horizontally, the position will shift due to the small clamping area.
