Description

Technical Field

[0001] This invention relates to the field of automotive parts installation equipment, specifically a top-pressing device for connecting and installing parts. Background Technology

[0002] The bottom end of the automotive shock absorber spring is connected between the two ends of the shock absorber frame. The actual assembly and installation steps are as follows: one end of the shock absorber frame is first connected via a pin; then the spring is constrained between the shock absorber frame and the connection structure at the bottom of the car; finally, a hydraulic cylinder pushes the other end of the shock absorber frame to the pin hole connector at the bottom of the car and inserts the pin. However, this method, relying solely on the existing hydraulic cylinder pressing, cannot ensure that the connecting parts, such as the connecting holes, are simultaneously stressed and contact the corresponding holes in the car's connecting parts. This can easily cause excessive stress and deformation in a single point on the shock absorber frame and other connecting parts, and can also cause misalignment at the contact point between the spring and the shock absorber frame, hindering subsequent reinforcement and resulting in low work efficiency. Therefore, to address these problems, a pressing device for connecting and installing parts is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a pressing device for connecting and installing parts in order to solve the above-mentioned problems.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a top-pressing device for connecting and installing parts, comprising a support cylinder, a top-pressing arm plate, a first-point top-pressing contact, a compensation and adjustment cylinder, and a second-point top-pressing contact. The output end of the support cylinder is connected to a second slotted hole on one side of the top-pressing arm plate via a follower connection mechanism. One end of an assisting brace and the second-point top-pressing contact are rotatably installed alternately in the first slotted hole on the other side of the top-pressing arm plate. The first-point top-pressing contact is connected to the connecting hole at the other end of the assisting brace. The first-point top-pressing contact and the second-point top-pressing contact act on two connection points on the parts to be top-pressed and connected. One side of the middle of the top-pressing arm plate is rotatably connected to the inside of a U-shaped plate via a rotating shaft. The compensation and adjustment cylinder is not limited to being installed on the first-point top-pressing contact, and the output end of the compensation and adjustment cylinder is rotatably connected to one end of a screw via a bearing.

[0005] In a further technical solution, the parts to be connected by pressure are not limited to automotive shock absorber springs and carriers, and at least two connection points are provided on both the automotive shock absorber springs and the carriers.

[0006] A further technical solution is that a spring end sleeve is installed at one end of the car shock absorber spring, the screw hole in the middle of the spring end sleeve is threaded to the other end of the screw, and the spring end sleeve is located in the spring end mounting slot. The spring end mounting slot is opened on the shock absorber connecting arm, and one end of the shock absorber connecting arm is set as the end to be connected. The end to be connected is in contact with the second point pressure contact member.

[0007] In a further technical solution, the carrier is provided with a first connecting hole and a second connecting hole, the first connecting hole being in contact with a first point pressure contact member, and the second connecting hole being in contact with a second point pressure contact member.

[0008] In a further technical solution, the top of the cylinder body of the supporting cylinder is fixedly mounted on a fixed seat, and one end of the fixed seat is connected to the bottom of the U-shaped plate through a position adjustment mechanism. Two symmetrically distributed guide holes and one screw hole are respectively opened at one end of the fixed seat.

[0009] In a further technical solution, the position adjustment mechanism includes guide rods and lead screws. One end of the lead screw is rotatably installed at the middle position of the bottom of the U-shaped plate, and one end of each of the two guide rods is fixedly installed at both ends of the bottom of the U-shaped plate. The lead screw is threadedly connected to the screw hole, and the other end of the guide rod slides through the inside of the guide hole for sliding contact.

[0010] In a further technical solution, the follower connection mechanism includes a U-shaped seat and slide rails. The two slide rails are respectively installed on the two side walls inside the same first strip hole, and the two ends of the U-shaped seat are slidably installed between the two slide rails.

[0011] In a further technical solution, a base plate is installed at the bottom end of the cylinder body of the supporting cylinder.

[0012] In a further technical solution, both the middle of the first point pressing contact and the middle of the second point pressing contact are provided with channels.

[0013] The beneficial effects of this invention are: By directly inserting the connecting bolts into the channel and connecting them to the corresponding bolt holes on another connector through the first or second connecting hole, the function of synchronously pressing the connection point and directly performing the bolt connection operation is realized. This avoids the situation where the other connection point on the same part is misaligned after one connection point is tightened. At the same time, the internal space of the channel can be fully inserted into the bolt tightening power tool, improving the efficiency of the press-fit connection.

[0014] The connected car shock absorber spring is in a compressible state, which reduces the degree of squeezing and wear between the spring end mounting slot and the spring end fitting connected to the car shock absorber spring end. This helps to prevent the car shock absorber spring connection end from shifting or displacing, and ensures the accuracy of the car shock absorber spring in place after subsequent connection.

[0015] By gradually separating the screw from the spring end sleeve while the compensating adjustment cylinder continuously contracts, the top of the screw is disengaged from the spring end mounting slot, thus preventing the support cylinder from extending directly without separating the screw from the spring end sleeve and causing accidental damage.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Please see Figure 1-4 As shown, a pressing device for connecting and installing parts includes a support cylinder 1, a pressing arm plate 2, a first-point pressing contact 3, a compensation and adjustment cylinder 310, and a second-point pressing contact 4. The output end of the support cylinder 1 is connected to a second slot 220 located on one side of the pressing arm plate 2 via a follower connection mechanism. A supporting diagonal brace 5 and a second-point pressing contact 4 are rotatably mounted alternately in the first slot 210 located on the other side of the pressing arm plate 2. The component 3 is connected to the connecting hole 510 located at the other end of the auxiliary brace plate 5. The first point pressing contact component 3 and the second point pressing contact component 4 act on two points of connection on the part to be pressed and connected. The middle side of the pressing arm plate 2 is rotatably connected to the inside of the U-shaped plate 8 through a rotating shaft. The compensation and adjustment cylinder 310 is not limited to being installed on the first point pressing contact component 3, and the output end of the compensation and adjustment cylinder 310 is rotatably connected to one end of the screw 330 through the bearing 320.

[0024] The component to be connected by pressure is a type of automotive shock absorber spring A, and the automotive shock absorber spring A has at least two connection points. One end of the automotive shock absorber spring A is fitted with a spring end sleeve A2. The screw hole in the middle of the spring end sleeve A2 is threadedly connected to the other end of the screw 330. The spring end sleeve A2 is located in the spring end mounting slot A11. The spring end mounting slot A11 is opened on the shock absorber connecting arm A1, and one end of the shock absorber connecting arm A1 is set as the end to be connected A12. The end to be connected A12 is in contact with the second point pressure contact component 4.

[0025] like Figure 4As shown, the component to be pressed and connected is a carrier B, and the carrier B is provided with at least two connection points. The carrier B is provided with a first connection hole B1 and a second connection hole B2. The first connection hole B1 is in contact with the first point pressing contact 3, and the second connection hole B2 is in contact with the second point pressing contact 4. The middle part of the first point pressing contact 3 and the middle part of the second point pressing contact 4 are provided with channels, and the channel specifications are larger than the diameter of the first connection hole B1 and the diameter of the second connection hole B2. Because the angle between the assisting brace 5 and the other side of the top pressure arm plate 2 is an acute angle, the assisting brace 5 can be subjected to an upward thrust and the second point top pressure contact 4 is pushed upward, so that the first point top pressure contact 3 and the second point top pressure contact 4 respectively make firm contact with the first connecting hole B1 and the second connecting hole B2 that are abutting each other at the corresponding screw hole structure on the other connector. At this time, the worker directly inserts the connecting bolt into the channel and connects it with the corresponding screw hole structure on the other connector through the first connecting hole B1 or the second connecting hole B2, realizing the function of synchronous top pressure connection and direct bolt connection operation. This avoids the situation where the other connection on the same part is misaligned after one connection is tightened. At the same time, the internal space of the channel can be directly inserted into the bolt tightening power tool, improving the efficiency of top pressure connection.

[0026] like Figure 3 As shown, the top of the cylinder body of the supporting cylinder 1 is fixedly installed on the fixed seat 7, and one end of the fixed seat 7 is connected to the bottom of the U-shaped plate 8 through a position adjustment mechanism. Two symmetrically distributed guide holes 710 and a screw hole are respectively opened at one end of the fixed seat 7. The position adjustment mechanism includes a guide rod 9 and a lead screw 10. One end of the lead screw 10 is rotatably installed at the middle position of the bottom of the U-shaped plate 8. One end of the two guide rods 9 is fixedly installed at both ends of the bottom of the U-shaped plate 8. The lead screw 10 is threadedly connected to the screw hole. The other end of the guide rod 9 slides through the inside of the guide hole 710 and makes sliding contact. Under the synergistic effect of the extension or retraction of the support cylinder 1, the U-shaped plate 8 connected to it is pushed upward or pulled downward by rotating the lead screw 10. This can adjust the structural part connected to the U-shaped plate 8 to be in a position height adjustment state, ensuring the effectiveness of the first point pressing contact 3 and the second point pressing contact 4 in contacting the connection point on the part to be pressed.

[0027] like Figure 2 As shown, the follow-up connection mechanism includes a U-shaped seat 6 and a slide rail 11. The two slide rails 11 are respectively installed on the two side walls inside the same first strip hole 210. The two ends of the U-shaped seat 6 are slidably installed between the two slide rails 11, which can avoid hindering the extension and retraction of the output end of the support cylinder 1.

[0028] like Figure 1As shown, a base plate 12 is installed at the bottom of the cylinder body of the supporting cylinder 1, which can ensure that the whole is placed in an upright position.

[0029] Basic top-compression principle: Taking car shock absorber spring A as an example, such as... Figure 1 As shown: Step 1: The screw 330 indirectly connected to the first point pressure contact 3 extends into the spring end mounting slot A11 and is threadedly connected to the middle of the spring end sleeve A2 located in the spring end mounting slot A11. At the same time, the top of the first point pressure contact 3 abuts against the surface of the shock-absorbing connecting arm A1. The second step is that the top surface of the second point pressure contact 4 abuts against the end A12 to be connected on the shock-absorbing connecting arm A1, and the left end of the shock-absorbing connecting arm A1 is pre-connected to the corresponding part on the car through a pin. Third step: Under the support of the U-shaped plate 8 on the rotating connected top pressure arm plate 2, the support cylinder 1 retracts and moves one side of the top pressure arm plate 2 connected by the position adjustment mechanism downward and the other side upward. Since the angle between the assisting brace plate 5 and the other side of the top pressure arm plate 2 is an acute angle, the assisting brace plate 5 can be pushed upward. At the same time, the end A1 to be connected on the top pressure arm plate 2 is pushed upward into the shaft pin connector by the second point top pressure contact piece 4. Fourth step: When the other end of the assisting diagonal brace 5, which was pushed upward by the pressure in the third step, drives the first point of the rolling connection top contact 3 to move upward, the extended compensation and adjustment cylinder 310 simultaneously pushes the spring end sleeve A2 connected by the bearing 320 and the screw 330 upward, so that the connected car shock absorber spring A is in a compressible state, reducing the degree of extrusion and wear between the spring end mounting slot A11 and the spring end sleeve A2 connected to the end of the car shock absorber spring A, and further helping to avoid the displacement of the connecting end of the car shock absorber spring A, ensuring the accuracy of the car shock absorber spring A in place after the subsequent connection is completed; Step 5: After the shaft pin of the end A1 to be connected on the top pressure arm plate 2 is installed, the compensation adjustment cylinder 310 slowly retracts to accurately reset the spring end sleeve A2 connected by the bearing 320 and the screw 330 into the spring end mounting slot A11. At the same time, the car shock absorber spring A returns to its normal working state. Step 6: While rotating the screw 330 to gradually separate from the spring end sleeve A2, the compensation and adjustment cylinder 310 continues to contract, so that the top of the screw 330 is completely removed from the spring end mounting slot A11, thus avoiding the situation where the support cylinder 1 extends directly without separating the screw 330 from the spring end sleeve A2, which could cause accidental damage. Step 7: The support cylinder 1 is fully extended to completely separate the first point pressing contact 3 and the second point pressing contact 4 from the shock absorber connecting arm A1, thus completing the pressing connection operation of the car shock absorber spring A.
