[0002] A fixture refers to a device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. The suspension is a general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel) of the car. Its function is to transmit the force and torque acting between the wheel and the frame, and to cushion the impact force transmitted to the frame or body by the uneven road surface, and reduce the vibration caused by it, so as to ensure that the car can run smoothly.

[0003] During the processing of the suspension control arm, the processed suspension control arm needs to be fixed on the fixture for inspection and burr removal, and different types of control arms require matching fixtures to fix them. When fixing, the limiting structure on the fixture needs to be connected to the control arm in turn to fix the control arm. This operation is required when each control arm is fixed on the fixture. The speed of fixing the control arm on the fixture is very slow, and if a different control arm is replaced for processing, a different matching fixture needs to be replaced.

[0004] Based on this, the present invention designs a vehicle suspension control arm clamp to solve the above-mentioned problem that different control arms require different corresponding clamps and the efficiency of the clamp in fixing the control arm is low. Summary of the invention

[0017] See also Figure 1-Figure 7 The present invention provides a technical solution: a vehicle suspension control arm clamp, comprising an outer frame 4, a placement plate 3 is fixedly connected inside the outer frame 4, connecting rods 2 are fixedly connected to the top and sides of the outer frame 4, and a plurality of connecting rods 2 are slidably connected to a pressure plate 1, and a positioning clamping assembly is arranged at the top of the outer frame 4, and the positioning clamping assembly can clamp and fix suspension control arms of different forms placed on the placement plate 3 on the placement plate 3, and a plurality of pre-positioning holes are opened on the top of the placement plate 3, and a pre-positioning shaft is inserted into the pre-positioning hole; When the above scheme is put into actual use, when the control arm is installed on the fixture, the position of the control arm is initially restricted by inserting the pre-positioning shaft into a suitable pre-positioning hole, so that the control arm will not move on the placement plate 3 within a large range, and then by pressing down the pressure plate 1, the positioning clamping assembly is driven to extend from the four sides of the placement plate 3 to the inner side of the placement plate 3, thereby contacting the control arm and fixing the control arm on the placement plate 3, thereby fixing the control arm. The advantage of this is that the control arm is fixed by the positioning clamping assembly, which can effectively fix control arms of different shapes, and there is no need to replace different clamps for fixing control arms of different shapes, which can effectively improve the installation efficiency of the control arm on the fixture.

[0018] As a further solution of the present invention, the alignment clamping assembly includes a sliding block 14, which is slidably arranged at the top of the outer frame 4, and a swing rod 12 is rotatably connected to the outer frame 4. The front end of the swing rod 12 is rotatably connected to the top of the sliding block 14, and the top of the swing rod 12 is rotatably connected to the base 11, and the top of the sliding block 14 is fixedly connected to the fixed shaft 7, and the front end of the fixed shaft 7 is provided with a torsion spring for resetting the fixed block 13, and the top of the base 11 is provided with a sliding rod 9, and the top of the sliding rod 9 is sleeved with a connecting plate 8, and the top of the connecting plate 8 is fitted with the bottom end of the pressing plate 1, and the top of the sliding rod 9 slides through the pressing plate 1 and is arranged above the pressing plate 1, and the sliding rod 9 is slidably connected to the sliding shaft 15 inside, and the top of the sliding rod 9 is fixedly connected to A docking column 20 for resetting the sliding shaft 15, a pushing block 18 is slidably connected inside the base 11, a stopper 19 is fixedly connected inside the base 11, a first spring 16 for resetting the pushing block 18 is fixedly connected to the stopper 19, a docking column 20 for docking with the sliding rod 9 is fixedly connected inside the base 11, latch blocks 21 are slidably connected to both sides of the top of the sliding rod 9, a docking groove 22 for docking with the latch block 21 is provided inside the top of the sliding shaft 15, a tooth plate 10 capable of engaging with the pushing block 18 is fixedly connected to the side wall of the outer frame 4, the top of the latch block 21 is a smooth inclined surface, a groove for docking with the latch block 21 is provided at the bottom of the base 11, and a fixed block 13 is rotatably connected to the front end of the fixed shaft 7; When the above scheme is put into practical use, when the pressing plate 1 is pressed down, the pressing plate 1 will drive the sliding rod 9 to slide downward through the connecting plate 8, and the sliding rod 9 will slide downward along the sleeve 17 until it contacts the pushing block 18, and then the sliding rod 9 will slide down and drive the base 11 to slide down together, and the base 11 will press down to drive the swing rod 12 to rotate. Since the rear end of the swing rod 12 is rotatably connected to the outer frame 4, the top of the swing rod 12 moves downward so that its front end pushes the sliding block 14 to slide forward, and the sliding block 14 drives the fixed shaft 7 to slide toward the inside of the placement plate 3 and contacts the surface of the control arm through the fixed block 13. If the fixed shafts 7 on the opposite side contact the control arm through the fixed block 13, the control arm will be clamped and fixed at this time, but since the control arm is not a regular shape, this will result in different movement distances of the fixed shafts 7 in the same row in contact with the surface of the control arm. If one of the fixed shafts 7 in a row is fixed The shaft 7 contacts the surface of the control arm through the fixed block 13, but the remaining fixed shaft 7 has not yet contacted the control arm. At this time, if the pressure plate 1 is continued to be pressed down to drive the base 11 to slide, the sliding will be hindered. In order to make a row of fixed shafts 7 all contact the surface of the control arm, the pressure plate 1 is continued to be applied. The fixed shaft 7 that has contacted the control arm, the sliding rod 9 inside the base 11 above it continues to apply pressure so that the sliding rod 9 squeezes the pushing block 18, so that the pushing block 18 pushes the first spring 16 to compress and slide the pushing block 18 to the outside of the base 11. The pushing block 18 extends to the outside of the base 11 and docks with the toothed plate 10 on the outside of the base 11. The position of the base 11 is fixed by the toothed plate 10. At this time, the sliding rod 9 can continue to slide downward, and when the sliding rod 9 slides to the internal sliding shaft 15 and contacts the docking column 20, the docking column 20 will push the sliding shaft 15 to compress the docking column 20 above the sliding rod 9. Figure 7As shown, after the sliding shaft 15 slides upward, the docking groove 22 inside it will gradually slide to the position where it docks with the latch block 21. Since the top of the base 11 is continuously subjected to the pressure of the pressure plate 1 at this time, and the top of the latch block 21 will be inclined, according to physical common sense, the downward pressure of the base 11 on the latch block 21 can be decomposed into a downward force and a force inward of the docking groove 22. At this time, under the pressure of the base 11, the latch block 21 will be pushed inwardly of the docking groove 22 until the latch block 21 is separated from the support of the base 11, and then the pressure plate 1 presses down on the base 11, so that the base 11 can slide relatively on the sliding rod 9. At this time, the pressure of the base 11 will no longer be transmitted to the sliding rod 9, and due to the reset elastic force of the first spring 16, the push block 18 will tightly clamp the sliding rod 9 from both sides, and the sliding rod 9 will not reset. At this time, the base 11 is The tooth plate 10 is fixed, and the fixed shaft 7 can still have a corresponding clamping effect on the control arm after being released from the extrusion of the pressure plate 1. Through the above actions, each row of fixed shafts 7 can contact the control arm through the fixed block 13 in turn to fix the control arm. The advantage of this is that when fixing the control arm, the fixed block 13 at the front end of the fixed shaft 7 contacts the control arm for limiting. When the same pressure is applied through the pressure plate 1, the fixed shaft 7 at its bottom can push the pushing block 18 to slide through the sliding rod 9. The position of the fixed shaft 7 is fixed by docking the pushing block 18 with the tooth plate 10, and then the sliding shaft 15 is moved up relative to the sliding rod 9 to make the pin block 21 slide to the inside of the docking groove 22, so that the base 11 and the sliding rod 9 are separated from sliding, thereby individually controlling the forward movement of different fixed shafts 7, and clamping and fixing different control arms in the same way.

[0019] As a further solution of the present invention, a fixing frame 5 is fixedly connected to the top of the outer frame 4, a fixing cylinder 6 is fixedly connected to the top of the fixing frame 5, and an output end of the fixing cylinder 6 is fixedly connected to the top of the pressing plate 1; When the above scheme is put into actual use, when the pressure plate 1 is controlled to be pressed down, the downward pressure is applied by the fixed cylinder 6 to drive the pressure plate 1 to slide down as a whole. The fixed cylinder 6 is fixedly connected to the outer frame 4 through the fixed frame 5, so that the output end of the fixed cylinder 6 applies pressure to drive the pressure plate 1 to move downward effectively.

[0020] As a further solution of the present invention, the front end of the fixing block 13 is fixedly connected with an anti-skid pad with a large friction coefficient; When the above solution is put into practical use, after the fixing block 13 contacts the control arm, the anti-skid pad increases the friction force so that the fixing block 13 and the surface of the control arm are more firmly fixed under the action of pressure.

[0021] As a further solution of the present invention, the outer wall of the sliding rod 9 can be completely fitted with the inner wall of the sleeve 17, the sliding shaft 15 can be completely fitted with the inner wall of the sliding rod 9, and the cross-sectional diameter of the docking column 20 is the same as that of the sliding shaft 15; When the above solution is put into actual use, the two are completely fitted together so that the sliding rod 9 slides inside the sleeve 17 without causing deviation in other directions, thereby ensuring the docking accuracy.

[0022] Working principle: When the control arm is installed on the fixture, the position of the control arm is initially restricted by inserting the pre-positioning shaft into the appropriate pre-positioning hole, so that the control arm will not move on the placement plate 3 within a large range, and then the pressure plate 1 is pushed down by the fixed cylinder 6, and the pressure plate 1 will drive the sliding rod 9 to slide downward through the connecting plate 8, and the sliding rod 9 will slide downward along the sleeve 17 until it contacts the pushing block 18, and then the sliding rod 9 will drive the base 11 to slide down together, and the base 11 will press down to drive the swing rod 12 to rotate. Since the rear end of the swing rod 12 is rotatably connected to the outer frame 4, the top of the swing rod 12 moves downward so that its front end pushes the sliding block 14 to slide forward, and the sliding block 14 drives the fixed shaft 7 to slide toward the inside of the placement plate 3 and contacts the surface of the control arm through the fixed block 13. If the fixed shafts 7 on the opposite side contact the control arm through the fixed block 13, the control arm will be clamped and fixed at this time, but since the control arm is not a regular shape, this will result in the fixing of the same column. The movement distance of the shaft 7 in contact with the surface of the control arm will not be the same. If one of the fixed shafts 7 in a row of fixed shafts 7 contacts the surface of the control arm through the fixed block 13 but the remaining fixed shafts 7 have not yet contacted the control arm, continuing to press the pressure plate 1 downward to drive the base 11 to slide will be hindered. In order to make all the fixed shafts 7 in a row contact with the surface of the control arm, continue to apply pressure to press the pressure plate 1 downward. The fixed shaft 7 that has already contacted the control arm, the sliding rod 9 inside the base 11 above it continues to apply pressure so that the sliding rod 9 squeezes the pushing block 18, so that the pushing block 18 pushes the first spring 16 to compress and slide the pushing block 18 toward the outside of the base 11. The pushing block 18 extends toward the outside of the base 11 and docks with the toothed plate 10 on the outside of the base 11. The position of the base 11 is fixed by the toothed plate 10. At this time, the sliding rod 9 can continue to slide downward, and when the sliding rod 9 slides to the internal sliding shaft 15 and contacts the docking column 20, the docking column 20 will push the sliding shaft 15 to compress the docking column 20 above the sliding rod 9. Figure 7As shown, after the sliding shaft 15 slides upward, the docking groove 22 inside it will gradually slide to the position where it docks with the latch block 21. Since the top of the base 11 is continuously subjected to the pressure of the pressure plate 1 at this time, and the top of the latch block 21 is inclined, according to common sense of physics, the downward pressure of the base 11 on the latch block 21 can be decomposed into downward force and force toward the inside of the docking groove 22. At this time, under the pressure of the base 11, the latch block 21 will be pushed toward the inside of the docking groove 22 until the latch block 21 is separated from the support of the base 11, and then the pressure plate 1 presses down the base 11, that is, The base 11 can slide relatively on the sliding rod 9. At this time, the pressure of the base 11 will no longer be transmitted to the sliding rod 9, and due to the reset elastic force of the first spring 16, the pushing block 18 will tightly clamp the sliding rod 9 from both sides, and the sliding rod 9 will not reset. At this time, the base 11 is fixed by the tooth plate 10, and the fixed shaft 7 can still have a corresponding clamping effect on the control arm after being separated from the extrusion of the pressure plate 1. Through the above actions, each column of fixed shafts 7 can contact the control arm through the fixed block 13 in turn to fix the control arm.
