Description

Technical Field

[0001] The utility model relates to the technical field of spring shock absorber assembly, in particular to an adjustable spiral spring pressing tool for a shock absorber assembly. Background Technique

[0002] A shock absorber is used to suppress the oscillation when the spring rebounds after absorbing shock and the impact from the road surface. It is widely used in automobiles to accelerate the attenuation of the vibration of the vehicle frame and the body, so as to improve the ride comfort of the automobile. When passing through an uneven road surface, although the shock-absorbing spring can filter the road vibration, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] During the assembly process, the spiral spring in the free state needs to be compressed downward to the designed state before the subsequent assembly can be carried out. Since the spiral spring used in the automobile shock absorber assembly has the characteristics of large wire diameter and high design load of the steel wire, the installation difficulty is increased. There is a risk of the spring bursting when using the manual installation method, and the safety is low; when the traditional spring pressing tool compresses, it only contacts the spring at one point, there are risks of slipping out, bursting out, and skewed pressing; the traditional spring pressing tool cannot be adjusted according to parameters such as the outer diameter, height, and number of turns of the spring, resulting in poor applicability and reduced flexibility in use. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an adjustable spiral spring pressing tool for a shock absorber assembly to solve the above problems existing in the prior art.

[0005] The technical solution of the present utility model to solve the above technical problems is as follows: An adjustable helical spring pressing tooling for a shock absorber assembly includes a fixed base plate for fixing on a press. A first circular arc notch is provided on one side edge of the fixed base plate. One end of the side edge of the fixed base plate where the first circular arc notch is provided is hinged to one end of the side edge of a movable base plate. The other end of the side edge of the movable base plate hinged to the fixed base plate is locked with the fixed base plate through a first locking mechanism. A second circular arc notch is provided on the movable base plate. When the fixed base plate and the movable base plate are locked through the first locking mechanism, the first circular arc notch and the second circular arc notch are communicated. A radial guiding mechanism is arranged at the bottom of the fixed base plate, and a radial guiding mechanism is also provided at the bottom of the movable base plate. A guiding block that can move in the radial direction of the first circular arc notch is slidably arranged on the radial guiding mechanism at the bottom of the fixed base plate, and a guiding block that can move in the radial direction of the second circular arc notch is slidably arranged on the radial guiding mechanism at the bottom of the movable base plate. Second locking mechanisms for locking the guiding blocks are provided on both the fixed base plate and the movable base plate. A vertically arranged threaded rod is rotatably arranged at the bottom of the guiding block. A threaded movable block is threadedly connected to the threaded rod. The threaded movable block is used to move up and down along the length direction of the threaded rod under the rotation of the threaded rod. A contact block is rotatably arranged on the side wall of the threaded movable block facing the inner sides of the first circular arc notch and the second circular arc notch. The contact block can rotate axially around a horizontal axis.

[0006] The beneficial effects of the present utility model are as follows: The tooling wraps the spring in all directions, with high safety. The tooling contacts the spring at multiple points, fixes the spring in the circumferential direction, and then presses it, so that the spring will not be skewed during the pressing process. The contact position between the tooling and the spring is adjustable, which can adapt to springs of various models without the need to frequently replace the tooling.

[0007] On the basis of the above technical solution, the present utility model can be further improved as follows.

[0008] Further, a vertically arranged guiding column is fixedly provided at the bottom of the guiding block. The side wall of the guiding column is in sliding contact with the side wall of the threaded movable block to limit the rotation of the threaded movable block.

[0009] The beneficial effect of adopting the above further scheme is that by arranging the guiding column, the threaded movable block can be restricted to prevent the threaded movable block from rotating.

[0010] Further, the number of the guiding columns is two. The two guiding columns are respectively arranged on both sides of the threaded movable block. A bottom plate is fixedly connected between the bottom ends of the two guiding columns. The bottom end of the threaded rod is rotatably connected to the bottom plate and passes through and extends out of the bottom plate.

[0011] The beneficial effects of adopting the above further solution are as follows: By setting the bottom plate, the stability of the rotation of the threaded rod is ensured.

[0012] Further, a positioning ring is threadedly sleeved on the lower part of the threaded rod, and the bottom end of the positioning ring rotatably abuts against the bottom plate.

[0013] The beneficial effects of adopting the above further solution are as follows: By threadedly sleeving a positioning ring on the lower part of the threaded rod, the downward movement of the positioning ring is restricted by the bottom plate. The top of the threaded rod only needs to be rotatably connected to the bottom of the guide block, without additional limiting, ensuring that the threaded rod can only rotate axially and will not move up and down.

[0014] Further, a nylon protection block is fixedly provided on the contact block.

[0015] The beneficial effects of adopting the above further solution are as follows: The setting of the nylon protection block can avoid the collision damage between the helical spring and the metal contact block. After the nylon protection block is in contact with and stressed by the spring, it can rotate around the horizontal axis, so that the maximum contact area is always maintained between the nylon protection block and the spring.

[0016] Further, the radial guiding mechanism includes a guiding seat fixedly installed at the bottom of the fixed base plate or the movable base plate. A first T-shaped sliding groove is provided on the guiding seat, and a T-shaped block matching the first T-shaped sliding groove is provided on the upper part of the guide block. The T-shaped block is slidably arranged in the first T-shaped groove.

[0017] The beneficial effects of adopting the above further solution are as follows: The guide block is slidably connected to the first T-shaped sliding groove on the guiding seat through the T-shaped block, ensuring that the guide block can only move along the length direction of the first T-shaped sliding groove and will not move up and down.

[0018] Further, the second locking mechanism includes a locking bolt threadedly connected to the fixed base plate or the movable base plate. After passing through the fixed base plate or the movable base plate, the locking bolt abuts against the top of the guide block.

[0019] The beneficial effects of adopting the above further solution are as follows: By tightening the locking bolt, the locking of the guide block is achieved.

[0020] Further, a second T-shaped groove with the same length direction as the length direction of the first T-shaped sliding groove is provided at the top end of the guide block. A locking nut that can move along the length direction of the second T-shaped groove is arranged in the second T-shaped groove. The locking bolt is threadedly connected to the locking nut.

[0021] The beneficial effects of adopting the above further solution are as follows: By tightening the locking bolt, the locking nut is driven to move upward, so that the locking nut abuts against the top wall of the second T-shaped groove, thereby achieving the locking of the guide block.

[0022] Further, the first locking mechanism includes a locking seat fixed on the fixed substrate and a connecting seat fixed on the movable substrate. A gravity block is hinged to one side of the locking seat away from the fixed base. A hook is provided at the bottom of one end of the gravity block away from the locking seat. A first guiding inclined surface is provided at the lower part of the side of the hook away from the locking seat. A second guiding inclined surface is provided at the upper part of the side of the connecting seat away from the movable substrate.

[0023] The beneficial effect of adopting the above further solution is that the arrangement of the first guiding inclined surface and the second guiding inclined surface enables the hook to be first lifted when approaching the connecting seat, and then gradually move to the side of the connecting seat away from the fixed substrate and fall, buckling on the side of the connecting seat away from the fixed substrate to achieve locking.

[0024] Further, a vertically arranged scale is provided on the guiding block.

[0025] The beneficial effect of adopting the above further solution is that the setting of the scale can record the contact positions of springs of different models, facilitating the quick debugging and switching between springs of different models. Description of the Drawings

Detailed Embodiments

[0032] The principles and features of the present utility model are described below with reference to the drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0033] As Figure 1 , Figure 2 shown, an embodiment of the present utility model includes a fixed substrate 1 for being fixed on a press. A first circular arc-shaped notch 2 is provided on one side edge of the fixed substrate 1. One end of the side edge of the fixed substrate 1 where the first circular arc-shaped notch 2 is provided is hinged to one end of the side edge of a movable substrate 3. Specifically, the fixed substrate 1 and the movable substrate 3 are hinged through a vertically arranged connecting shaft. The other end of the side edge of the movable substrate 3 hinged to the fixed substrate 1 is locked with the fixed substrate 1 through a first locking mechanism. A second circular arc-shaped notch 4 is provided on the movable substrate 3. When the fixed substrate 1 and the movable substrate 3 are locked through the first locking mechanism, the first circular arc-shaped notch 2 and the second circular arc-shaped notch 4 communicate with each other.

[0034] At the bottom of the position where the fixed substrate 1 is connected to the first locking mechanism, an L-shaped support frame is fixedly provided. After the first locking mechanism locks and fixes the fixed substrate 1 and the movable substrate 3, the support frame supports the bottom of the movable substrate 3.

[0035] In order to facilitate driving the movable substrate 3 to rotate around the hinge point of the fixed substrate 1 and the movable substrate 3, a handle is provided on the upper surface of the movable substrate 3 near the first locking mechanism.

[0036] A radial guiding mechanism is provided at the bottom of the fixed substrate 1, and a radial guiding mechanism is provided at the bottom of the movable substrate 3. In a preferred embodiment of the present utility model, the number of the radial guiding mechanisms at the bottom of the fixed substrate 1 is two, and the number of the radial guiding mechanisms at the bottom of the movable substrate 3 is one. After the movable substrate 3 is locked and connected to the fixed substrate 1, the three radial guiding mechanisms are evenly distributed.

[0037] A guide block 5 that can move in the radial direction of the first arc-shaped notch 2 is slidably provided on the radial guide mechanism at the bottom of the fixed substrate 1. A guide block 5 that can move in the radial direction of the second arc-shaped notch 4 is slidably provided on the radial guide mechanism at the bottom of the movable substrate 3. Second locking mechanisms for locking the guide block 5 are provided on both the fixed substrate 1 and the movable substrate 3. A vertically arranged threaded rod 6 is rotatably provided at the bottom of the guide block 5. A threaded movable block 7 is threadedly connected to the threaded rod 6. The threaded movable block 7 is used to move up and down along the length direction of the threaded rod 6 under the rotation of the threaded rod 6. A contact block 8 is rotatably provided on the side wall of the threaded movable block 7 facing the inner sides of the first arc-shaped notch 2 and the second arc-shaped notch 4. The contact block 8 can rotate axially about a horizontal axis. Specifically, a horizontally arranged rotating shaft is provided on the side wall of the contact block 8, and the rotating shaft is rotatably connected to the threaded movable block 7. In order to improve the smoothness of the rotation of the contact block 8, a groove can be provided on the inner wall of the threaded movable block 7, and a bearing is fixedly installed in the groove. The rotating shaft is fixedly connected to the inner wall of the inner ring of the bearing.

[0038] A vertically arranged scale 24 is provided on the guide block 5. The scale 24 is arranged close to the threaded movable block 7. The setting of the scale 24 can record the contact positions of springs 25 of different models, facilitating the quick debugging and switching between springs 25 of different models.

[0039] In an embodiment of the present invention, a vertically arranged guide post 9 is fixedly provided at the bottom of the guide block 5. The guide post 9 is a square post. The side wall of the threaded movable block 7 for abutting against the guide post 9 is a vertically arranged plane. The side wall of the guide post 9 is slidably abutted against the side wall of the threaded movable block 7 to limit the rotation of the threaded movable block 7. By providing the guide post 9, the threaded movable block 7 can be restricted to prevent the threaded movable block 7 from rotating.

[0040] Preferably, the number of the guide posts 9 is two. The two guide posts 9 are respectively arranged on both sides of the threaded movable block 7. A bottom plate 10 is fixedly connected between the bottom ends of the two guide posts 9. The two ends of the bottom plate 10 are detachably fixedly connected to the bottom ends of the two guide posts 9 by bolts or screws for convenient installation and disassembly. The bottom end of the threaded rod 6 is rotatably connected to the bottom plate 10 and passes through and extends out of the bottom plate 10. By providing the bottom plate 10, the stability of the rotation of the threaded rod 6 is ensured.

[0041] In an embodiment of the present invention, a light hole for the threaded rod 6 to pass through is provided on the bottom plate 10. A light rod section having the same length as the height of the bottom plate 10 is provided at the bottom of the threaded rod 6. The light rod section is rotationally matched with the light hole, thereby realizing the rotational connection between the threaded rod 6 and the bottom plate 10.

[0042] To facilitate driving the axial rotation of the threaded rod 6, the threaded rod 6 passes through and extends out of the bottom plate 10 and is fixedly sleeved with a rotating sleeve. Anti-slip patterns can also be provided on the outer peripheral surface of the rotating sleeve, or an anti-slip washer can be provided to facilitate manually rotating the threaded rod 6.

[0043] In a preferred embodiment, a positioning ring 11 is threadedly sleeved on the lower part of the threaded rod 6. The bottom end of the positioning ring 11 rotatably abuts against the bottom plate 10. By threadedly sleeving the positioning ring 11 on the lower part of the threaded rod 6, the downward movement of the positioning ring 11 is restricted by the bottom plate 10. The top of the threaded rod 6 only needs to be rotatably connected to the bottom of the guide block 5 without additional limiting, ensuring that the threaded rod 6 can only rotate axially and will not move up and down.

[0044] As Figure 4 shown, in a preferred embodiment of the present utility model, a nylon protection block 12 is fixedly provided on the contact block 8. Specifically, the nylon protection sleeve includes a fixed seat. A U-shaped groove is provided on the fixed seat. The contact block 8 is arranged in the U-shaped groove. The two side walls of the U-shaped groove are detachably and fixedly connected to the contact block 8 by screws. A baffle is fixedly provided on the side edge of the fixed seat close to the threaded movable block 7. When the bottom surface of the fixed seat abuts against the spring 25, the baffle presses against the outer wall of the spring 25. The setting of the nylon protection block 12 can prevent the spiral spring 25 from being bruised by contacting the metal contact block 8. After the nylon protection block 12 is in contact with and stressed by the spring 25, it can rotate around the horizontal axis, so that the maximum contact area is always maintained between the nylon protection block 12 and the spring 25.

[0045] As Figure 3 shown, in an embodiment of the present utility model, the radial guiding mechanism includes a guiding seat 13 fixedly installed at the bottom of the fixed substrate 1 or the movable substrate 3. The guiding seat 13 is connected to the fixed substrate 1 or the movable substrate 3 by bolts. A first T-shaped sliding groove 14 is provided on the guiding seat 13. The upper part of the guiding block 5 is provided with a T-shaped block 15 matching the first T-shaped sliding groove 14. The T-shaped block 15 is slidably arranged in the first T-shaped groove. The guiding block 5 is slidably connected to the first T-shaped sliding groove 14 on the guiding seat 13 through the T-shaped block 15, ensuring that the guiding block 5 can only move along the length direction of the first T-shaped sliding groove 14 and will not move up and down.

[0046] In an embodiment of the present utility model, the second locking mechanism includes a locking bolt 16 threadedly connected to the fixed substrate 1 or the movable substrate 3. The locking bolt 16 passes through the fixed substrate 1 or the movable substrate 3 and abuts against the top of the guiding block 5. By tightening the locking bolt 16, the locking of the guiding block 5 is achieved.

[0047] In another embodiment of the present utility model, a second T-shaped groove 17 with a length direction the same as that of the first T-shaped chute 14 is provided at the top of the guiding block 5. A locking nut that can move along the length direction of the second T-shaped groove 17 is provided in the second T-shaped groove 17. The locking bolt 16 is threadedly connected to the locking nut. By tightening the locking bolt 16, the locking nut is driven to move upward, so that the locking nut abuts against the top wall of the second T-shaped groove 17, thereby realizing the locking of the guiding block 5.

[0048] In a preferred embodiment of the present utility model, the first locking mechanism includes a locking seat 18 fixed on the fixed substrate 1 and a connecting seat 19 fixed on the movable substrate 3. A gravity block 20 is hinged to one side of the locking seat 18 away from the fixed base. A hook 21 is provided at the bottom of one end of the gravity block 20 away from the locking seat 18. A first guiding inclined surface 22 is provided at the lower part of the side of the hook 21 away from the locking seat 18. A second guiding inclined surface 23 is provided at the upper part of the side of the connecting seat 19 away from the movable substrate 3. The settings of the first guiding inclined surface 22 and the second guiding inclined surface 23 enable the hook 21 to be first lifted when approaching the connecting seat 19, and then gradually move to the side of the connecting seat 19 away from the fixed substrate 1 and fall, and buckle on the side of the connecting seat 19 away from the fixed substrate 1 to realize locking.

[0049] Working principle: When entering the spring 25 pressing process, the helical spring 25 has already been installed on the shock absorber at this time, and the lower end of the spring 25 contacts the lower spring 25 plate. At this time, first open the first locking mechanism, fix the lower end of the shock absorber on the fixed fixture of the spring pressing machine, and then close the movable substrate 3. The first guiding inclined surface 22 and the second guiding inclined surface 23 enable the hook 21 to be first lifted when approaching the connecting seat 19, and then gradually move to the side of the connecting seat 19 away from the fixed substrate 1 and fall, and buckle on the side of the connecting seat 19 away from the fixed substrate 1 to realize the locking of the fixed substrate 1 and the movable substrate 3; keep the shock absorber in a vertical state, adjust the front and rear positions of the guiding block 5 according to the outer diameter size of the spring 25, and after adjustment, tighten the locking bolt 16 so that the guiding block 5 no longer moves back and forth. Then rotate the threaded rod 6 to adjust the up and down position of the threaded movable block 7 so that the nylon protection block 12 just touches the helical spring 25. The self-locking effect of the threaded rod 6 can ensure that the threaded movable block 7 no longer moves up and down after adjustment. At this time, read and record the height of the threaded movable block 7 on the scale 24, and finally the spring pressing machine can be started to drive the tooling to press down the spring 25 to complete the pressing, and subsequent rapid adjustment can be carried out when assembling this product.

[0050] The present utility model wraps the spring 25 in all directions, with high safety; the tooling makes multi-point contact with the spring 25, fixes the spring 25 in the circumferential direction, and then presses it. The spring 25 will not be skewed during the pressing process; the contact position between the tooling and the spring 25 is adjustable, which can adapt to various models of springs 25, and there is no need to frequently replace the tooling.
