Description

Technical Field

[0001] The present application relates to the field of mechanical processing, and in particular to a retaining spring assembly jig. Background Art

[0002] The existing circlips are usually assembled by a built-in jig. The built-in jig has a limiting groove inside the jig, and the workpiece to be assembled is placed in the limiting groove for limiting. The circlip is then aligned with the workpiece in the limiting groove, and the circlip is pressed downward by the driving device so that the circlip is clamped in the clamping position of the workpiece. At this time, the relative position of the circlip and the workpiece can only be observed when the circlip is aligned with the workpiece. During the pressing process, the limiting groove is provided inside the jig and the driving device will block the circlip when pressing downward. Therefore, in the related art, the assembly of the circlip cannot be observed during the assembly process of the circlip, so that the circlip bayonet may not be aligned with the clamping position of the workpiece to be assembled, or the circlip may not be assembled in place, resulting in the need to reassemble the circlip on the workpiece, which in turn leads to low assembly efficiency of the circlip. Therefore, how to improve the assembly efficiency of the circlip is a technical problem that needs to be solved urgently. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a clamp spring assembly jig that can directly observe the clamp spring assembly status, thereby improving the assembly efficiency of the clamp spring.

Therefore, during the clamp assembly process, when the clamp is placed on the upper surface of the first limiting member, the clamp's latch can be aligned with the clamping position of the workpiece. Moreover, because the pusher operates the clamp horizontally on the first limiting member, the assembly status of the clamp is easier to observe during the assembly process, so that the pushing direction of the pusher can be adjusted in real time, thereby improving the efficiency of assembling the clamp. Therefore, compared with the existing built-in clamp assembly jig, the present application can improve the efficiency of clamp assembly.

[0035] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0036] Figure 1 This is a structural diagram of an embodiment of the circlip assembly jig of the present application. Figure 2 This is an exploded schematic diagram of an embodiment of the clamp assembly fixture of the present application. Figure 1 as well as Figure 2 As shown, the clamp assembly jig of the embodiment of the present application includes a first limiting member 100, a second limiting member 200, and a push member 400. The first end of the first limiting member 100 is provided with a first groove 101, and the second limiting member 200 is provided with a protrusion near the first end of the first limiting member 100. The protrusion can be embedded in the first groove 101, and the upper surface of the protrusion is flush with the upper surface of the first limiting member 100. A limiting hole 500 can be formed between the protrusion and the first groove 101. The limiting hole 500 is used to limit the workpiece to be assembled with the clamping spring so that the clamping position of the workpiece is flush with the upper surface of the first limiting member 100. The push member 400 is provided on the upper surface of the first limiting member 100, and the push member 400 can move horizontally along the upper surface of the first limiting member 100.

[0037] In the above embodiment, the protrusion of the first limiting member 100 is embedded in the first groove 101 of the second limiting member 200 to form the limiting hole 500, which limits the workpiece to be assembled with the retaining spring, so that the workpiece's mounting position is flush with the upper surface of the first limiting member 100. Therefore, during the assembly process of the retaining spring, when the retaining spring is placed on the upper surface of the first limiting member 100, the retaining opening of the retaining spring can be aligned with the mounting position of the workpiece. Moreover, because the pusher 400 operates the retaining spring horizontally on the first limiting member 100, the assembly status of the retaining spring can be more easily observed during the assembly process, so that the pushing direction of the pusher 400 can be adjusted in real time, thereby improving the efficiency of the retaining spring assembly.

[0038] The embodiments of the present application do not restrict how the first and second position-limiting members 100 and 200 are supported. For example, a clamp can be used to clamp the first and second position-limiting members 100 and 200 to maintain them in place. Similarly, a clamp can be used to clamp a workpiece passing through the position-limiting hole 500 to maintain the workpiece in place. In this case, the lower edge of the workpiece's mounting position is flush with the upper surface of the first position-limiting member 100. By horizontally pushing the push member 400 to apply force to the retaining spring, the retaining spring can be horizontally embedded in the mounting position to complete assembly. In other embodiments, a base 300 can also be provided to secure the workpiece and support the first and second position-limiting members 100 and 200.

[0039] Figure 4 3 is a schematic structural diagram of a base 300 of an embodiment of a clamp assembly fixture of the present application. Figure 4 As shown, the retaining spring assembly jig further includes a base 300, which is disposed below the first stopper 100 and the second stopper 200. By disposing the base 300 below the first stopper 100 and the second stopper 200, the first stopper 100 and the second stopper 200 can be supported, ensuring that the upper surface of the protrusion is flush with the upper surface of the first stopper 100, while also achieving a higher degree of integration of the retaining spring assembly jig.

[0040] The embodiment of the present application does not limit the shape and structure of the base 300. For example, Figure 3 As shown, the base 300 is configured as a square. In some embodiments, the edges of the base 300 are chamfered to improve the safety during the assembly of the retaining spring.

[0041] Figure 3 It is a structural diagram of another embodiment of the clamp spring assembly fixture of the present application. It is understandable that, referring to Figure 3 and Figure 4 As shown, the base 300 is provided with a through hole 302, and the second limiting member 200 includes a blocking block 202 and a limiting block 201. The blocking block 202 is partially passed through the through hole 302 and partially located above the base 300. The limiting block 201 is located above the base 300 and the second end of the limiting block 201 abuts against the side of the blocking block 202 close to the first limiting member 100. The first end of the limiting block 201 is protruding to form a protrusion.

[0042] By inserting the stopper 202 into the through hole 302 of the base 300, when the stopper 201 abuts the side of the stopper 202 near the first stopper 100, the stopper 201 is limited in a direction perpendicular to the abutment surface, thereby enabling the workpiece to be limited in position by the limit hole 500 formed after the stopper 201 is inserted into the first groove 101. When the pusher 400 pushes the retaining spring horizontally toward the stopper 202 to insert it into the locking position of the workpiece to be assembled, the stopper 202 always abuts the stopper 201, making it easier for the retaining spring to be inserted into the locking position of the workpiece to be assembled.

[0043] For example, Figure 3 and Figure 4 As shown, the blocking block 202 is configured as a square, and the through hole 302 of the base 300 is configured to match the outer contour of the blocking block 202. For example, if the blocking block 202 is square, the through hole 302 is configured as a square. The second end of the stopper 201 is flush with the side of the blocking block 202 adjacent to the first stopper 100. In some embodiments, the shape of the end of the protrusion formed by the protrusion of the first end of the stopper 201 can be adapted to the shape of the workpiece to be restrained. For example, if the workpiece is a screw, the end of the protrusion can be configured to be shaped like an inwardly concave arc.

[0044] It is understandable that referring to Figure 4 As shown, the base 300 is provided with a first strip groove 301, which is located below the limiting hole 500 and is used to embed the workpiece. By providing the first strip groove 301, the workpiece is embedded in the first strip groove 301 to fix the workpiece.

[0045] In the embodiment of the present application, the width and depth of the first strip groove 301 are not limited, and those skilled in the art can adjust them according to the size of the workpiece and the clamping position on the workpiece. Figure 4 As shown, the depth of the first strip groove 301 is set to allow the lower part of the workpiece to be embedded, so that the clamping position of the workpiece is higher than the upper surface of the base 300, thereby making the clamping position of the workpiece higher than the first limit member 100, thereby allowing the retaining spring to be always observed during the assembly process.

[0046] It is understandable that referring to Figure 4 As shown, the base 300 is provided with a second strip groove 303, which is wider than the first strip groove 301. The second strip groove 303 is located above the first strip groove 301, and the notch of the first strip groove 301 is located at the bottom of the second strip groove 303. The provision of the second strip groove 303 and the second groove width being wider than the first strip groove 301 facilitate the insertion of a workpiece into the first strip groove 301.

[0047] For example, refer to Figure 4The shape of the second strip groove 303 is the same as the shape of the notch of the first strip groove 301 , both of which are set to be long elliptical, and the width of the second strip groove 303 is wider than that of the first strip groove 301 , making it easier to embed the workpiece.

[0048] It is understandable that referring to Figure 1 As shown, the first end of the push member 400, which is close to the second stopper 200, protrudes toward the second stopper 200 and forms an escape groove. By protruding toward the second stopper 200 at the first end of the push member 400, which is close to the second stopper 200, and forming an escape groove, the visual area where the clamping position of the clamping spring and the workpiece to be assembled is unobstructed, making it easier to observe.

[0049] It is understandable that referring to Figure 1 As shown, the protruding portion of the first end of the push member 400 is configured as a step structure. By configuring the protruding portion of the first end of the push member 400 as a step structure, not only can the push member 400 better apply force to the retaining spring, but also the clamping position of the retaining spring and the workpiece to be assembled can be directly observed.

[0050] The embodiment of the present application does not limit the number of steps and the shape of the steps, and those skilled in the art can adjust them according to actual conditions. Figure 1 As shown, the protruding portion of the first end of the push member 400 is configured as a three-step step, including a first step, a second step, and a third step. The third step is higher than the second step, and the second step is higher than the first step. The first step is configured as a flat surface, and the second and third steps are configured as inclined surfaces. In other embodiments, each step of the step structure is configured as a rectangle.

[0051] It is understood that the second end of the pusher 400 is provided with a gripping portion, and the two ends of the gripping portion extend outward from both sides of the pusher 400. By providing the second end of the pusher 400 with two gripping portions, during the assembly process of the clamping spring, the pusher 400 can be gripped and the clamping spring can be pushed to better apply force to the clamping spring.

[0052] The embodiment of the present application does not limit the shape of the grip portion, as long as it is configured to be grippable. In some embodiments, such as Figure 1 As shown, the gripping portion of the pusher 400 is configured to be flat and block-shaped and protrudes toward both sides of the second end of the pusher 400. In other embodiments, the gripping portion may be configured to be cylindrical, or an anti-slip pad may be provided on the gripping portion to reduce the probability of slipping during the assembly of the retaining spring.

[0053] Refer to the following Figures 1 to 5 The following describes a clamp assembly jig according to an embodiment of the present application:

[0054] like Figure 5 As shown, the workpiece includes a first workpiece 600 and a second workpiece 700. For example, the second workpiece 700 is a screw and the first workpiece 600 is a workpiece base. When assembling the retaining spring, the first workpiece 600 and the second workpiece 700 are sequentially inserted into the first strip groove 301 to keep the first workpiece 600 and the second workpiece 700 in a fixed state. The stopper 202 is inserted into the through hole 302, and then the second end of the stopper 201 abuts the side of the stopper 202 close to the first stopper 100, and the protrusion of the stopper 201 abuts the first workpiece; and the notch of the first groove 101 is aligned with the first workpiece 600 and is moved horizontally toward the stopper 201. When the first end of the first stopper 100 abuts the first end of the stopper 201, the first workpiece 600 is retained in the retaining hole 500 formed between the first stopper 100 and the second stopper 200. At this time, the upper edge of the retaining hole 500 is flush with the lower edge of the clamping position of the first workpiece 600. At this time, the retaining spring is placed on the upper surface of the first limiting member 100 so that the retaining spring is flush with the engaging position of the first workpiece 600 and the retaining opening of the retaining spring is aligned with the engaging position of the first workpiece 600. After assembly is completed, the retaining spring can securely connect the second workpiece 700 and the first workpiece 600. Therefore, the retaining spring assembly jig of the embodiment of the present application can ensure that the engaging state of the retaining spring and the first workpiece 600 is always exposed during the retaining spring assembly process. Thus, during the process of pushing the pusher 400, the direction of the pusher 400 can be adjusted at any time according to actual conditions to adjust the retaining spring engagement force to ensure that the retaining spring engagement is always aligned with the engaging position of the first workpiece 600, thereby improving the retaining spring assembly success rate and thus improving the retaining spring assembly efficiency.

[0055] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
