Description

Technical Field

[0001] The present invention relates to the technical field of rework tooling, in particular to a buckle rework tooling. Background Art

[0002] A clip is installed on the shaft to limit the position of the nut and other structures. For example, the small motor assembly used to realize the electric adjustment of the steering wheel has a clip installed on the screw shaft to limit the position of the nut. If the clip can still rotate after installation, it is considered that the installation is not in place, which will cause the small motor assembly to generate noise during operation, so rework steps should be considered. During rework, if Figure 9 , it is necessary to separate the buckle from the shaft. The current common method is to use a conical structure connected to a press to expand the buckle to achieve the buckle detachment effect. However, since the buckle deforms freely during the expansion process, it is often difficult to detach from the shaft after expansion, resulting in the need for multiple expansion operations, which is inefficient. In response to the above problems, this application is proposed. Summary of the Invention

[0003] The purpose of the present invention is to provide a buckle rework tool, add a structure to guide the buckle deformation, avoid multiple operations, increase efficiency, and solve the problem that the buckle cannot be quickly and completely removed at this stage.

[0004] The present invention is achieved through the following technical solutions.

[0005] The buckle rework tool of the present invention includes a tool body, a pressing module and a guide module. The tool body includes a positioning groove, a positioning surface and a limit surface. The positioning groove is used to accommodate the shaft to be reworked and radially position it. The positioning surface is used to position the axial position of the shaft to be reworked. The guide module is installed on the tool body. The guide module has an arc-shaped contact surface for contacting the buckle, and the arc-shaped contact surface plays a role in guiding the buckle to deform; the pressing module includes a pressure head and a pressing part, and the pressure head can contact the limit surface to limit the pressing distance of the pressing module. The pressing part has a conical head, which can open the buckle; in the process of the pressing part pressing down and opening the buckle, the arc-shaped contact surface guides the buckle to deform, so that the buckle can be fully separated from the shaft.

[0006] The plane at the bottom of the buckle will change into an arc shape. Under this trend, the deformation of the buckle opening part near the shaft body will become larger; when the pressing part is pressed to the bottom, the lower end face of the pressure head contacts the limit surface, and the conical bottom of the pressing part completely presses open the bottom area of ​​the buckle opening end close to the shaft body, while not contacting the shaft body. At this time, the smallest opening of the buckle is larger than the diameter of the shaft body, so that the buckle can fall off naturally when the shaft body is taken out.

[0007] Furthermore, a receiving groove is provided between the positioning groove and the guide module and is provided through the tooling body. The receiving groove is used to receive the detached buckles. The buckles in the receiving groove can be blown out by providing an air nozzle around the tooling to avoid the accumulation of buckles that affects continuous work.

[0008] Furthermore, the receiving groove is a groove body with slopes on both sides. In the case where no blowing nozzle is provided, the slopes can be used to allow the buckles to be naturally discharged to both sides.

[0009] Furthermore, a pushing assembly is provided in the tool body for pushing the buckle that has been detached and remains at the guide module into the receiving groove.

[0010] Furthermore, the pushing assembly includes a push plate installed on the tooling body through a spring. During the process of opening the buckle, the push plate is compressed by the pressure head to compress the spring. After the pressure head returns, the push plate pushes the buckle into the accommodating groove under the action of the spring.

[0011] Furthermore, the guide module is detachably connected to the tool body, so as to facilitate replacement when worn.

[0012] Furthermore, the guiding module further includes an inserting portion, and the tooling body is provided with a slot for inserting the inserting portion.

[0013] Furthermore, a stabilizing groove is provided on the tool body, the slot is provided in the stabilizing groove, and the guide module is in contact with or interference fit with the inner wall of the stabilizing groove, thereby preventing the guide module from shaking significantly during operation.

[0014] Furthermore, the tool body is provided with a base portion, and structures such as through holes and bolt holes can be provided on the base portion to facilitate fixing the base portion on the work surface using connecting parts such as pins and bolts.

[0015] Furthermore, the pressing module also includes a pressing head handle connected to the pressing head, and the pressing head handle is used to connect the pressing module to a pressing drive structure such as a press.

[0016] The beneficial effects of the present invention are as follows: by setting a guiding module, a circular arc-shaped contact surface for guiding the deformation of the buckle is provided on the guiding module. In the process of stretching the buckle, the plane at the bottom of the buckle will produce an arc shape change. Under this trend, the deformation of the buckle opening part close to the shaft body will become larger. After the downward pressure is completed, the smallest part of the buckle opening is larger than the diameter of the shaft body, so that when the shaft body is taken out, the buckle can fall off naturally. The success rate of the buckle falling off in one time of this solution is greatly improved compared with the traditional solution, avoiding the problem of difficulty in improving efficiency due to multiple operations.

[0028] The present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] The buckle rework tool of the present invention is as follows: Figure 1-Figure 5 , including a tooling body 1, a pressing module 2 and a guiding module 3.

[0031] like Figure 3 、 Figure 4 The tooling body 1 includes a positioning groove 12, a positioning surface 13 and a limiting surface 15. The positioning groove 12 adopts a U-shaped groove body. The positioning groove 12 is used to accommodate the shaft body 5 to be reworked and radially position it. The positioning surface 13 is used to position the axial position of the shaft body to be reworked.

[0032] The tool body 1 is provided with a base portion 11, and the base portion 11 can be provided with structures such as through holes and bolt holes, so as to facilitate fixing the base portion 11 on the work surface by using connecting parts such as pins or bolts.

[0033] The guide module 3 is mounted on the tool body 1 . The guide module 3 has an arc-shaped contact surface 31 for contacting the buckle. The arc-shaped contact surface 31 serves to guide the buckle to deform.

[0034] Preferably, the guide module 3 is detachably connected to the tool body 1, so as to facilitate replacement when worn. Figure 4 The guide module 3 also includes an insertion portion 32. The tool body 1 is provided with a slot 17 for the insertion portion 32 to be inserted. The tool body 1 is provided with a stabilizing groove 16. The slot 17 is disposed in the stabilizing groove 16. The guide module 3 contacts or has an interference fit with the inner wall of the stabilizing groove 16 to prevent the guide module 3 from shaking significantly during operation.

[0035] The pressing module 2 includes a pressing head 21, a pressing part 22 and a pressing head handle 23. The pressing head handle 23 is used to connect the pressing module 2 with a pressing driving structure such as a press. The pressing head 21 can contact the limiting surface 15 to limit the pressing distance of the pressing module 2. The pressing part 22 has a conical head, which can open the buckle.

[0036] Working steps: Place the shaft body 4 with the buckle 5 in the positioning groove 12, make the end of the shaft body 4 contact the positioning surface 13, make the bottom of the buckle 5 contact the arc-shaped contact surface 31 of the guide module 3, and use a driving module such as a press, cylinder, hydraulic cylinder or manual press to achieve the pressing effect of the pressing module 2 to drive the pressing part 22 to press down and open the buckle. In this process, Figure 9 , the plane of the bottom of the buckle will change into an arc shape. Under this trend, the deformation of the buckle opening part near the shaft body will become larger; when the pressing part 22 is pressed to the bottom, the lower end surface of the pressing head 21 contacts the limiting surface 15, avoiding the pressing part 22 from contacting the shaft body, and the cone bottom of the pressing part 22 completely presses the buckle open, as shown in FIG. Figure 9 There is also a gap between the bottom of the buckle and the shaft body. At this time, the smallest opening of the buckle 5 is larger than the diameter of the shaft body, so that the buckle can fall off naturally when the shaft body is taken out.

[0037] Example 2:

[0038] On the basis of Example 1, Figure 2 In this embodiment, a receiving groove 14 is provided between the positioning groove 12 and the guide module 3 and runs through the tooling body 1. The receiving groove 14 is used to receive the detached buckles. By providing an air blowing nozzle around the tooling, air can be blown along the extension direction of the receiving groove 14 to blow out the buckles in the receiving groove 14, thereby avoiding the accumulation of buckles that affect continuous work.

[0039] Example 3:

[0040] On the basis of Example 2, Figure 6-Figure 8 In this embodiment, a pushing component is added. Specifically, a pushing component is provided in the tool body 1 for pushing the buckle that has been detached and remains at the guide module 3 into the accommodating groove 14.

[0041] The accommodating groove 14 is a groove body with slopes on both sides, and is high in the middle and low on both sides. In the case that no blowing nozzle is provided, the slope can be used to allow the buckles to be naturally discharged to both sides.

[0042] The pushing assembly includes a push plate 18 mounted on the tool body 1 through a spring 19. When the push plate 18 is large in area, the positioning surface 13 can be formed on the push plate 18. A hole for mounting the spring 19 is provided in the tool body 1. The push plate 18 is connected to a column, which extends into the hole and is connected to the spring 19. Figure 7 The left picture in the figure shows the initial state, and the right picture shows the state after the shaft body is installed. In the initial state, the push plate 18 is in a position close to the guide module 3 under the action of the spring 19. A structure for limiting the push plate 18 can be set on the tool body 1, or the push plate 18 can be limited by the guide module 3. After the shaft body is installed, the shaft body 4 pushes the push plate 18 and compresses the spring 19. The pressure head 21 drops and performs a buckle expansion action. After expansion, the pressure head 21 maintains its position. At this time, the worker withdraws the shaft body 4. Under the action of the pressure head 21, the push plate 18 cannot be released. After the shaft body 4 is withdrawn, the pressure head 21 performs an upward return action, and the push plate 18 moves toward the guide module 3 under the action of the spring 19. If the buckle does not fall into the accommodating groove 14, it will be pushed into the accommodating groove 14 by the push plate 18.
