[0002] like Figure 1 、 2 The figure shows a common part in a car universal joint, including a housing (1') with an inner hole in the housing, into which a steel ball (2') and a spring (3') are placed. The existing installation method is as follows: first, the steel ball is manually placed in the housing, and then the spring is manually placed in the part. The spring has a taper, with one end larger and the other end smaller. Since it is manually placed, the spring may be placed in the wrong direction. Figure 3 As shown in the figure, when correctly installed, the large end of the spring faces upwards and the small end faces downwards to contact the steel ball; Figure 4 As shown, when installed incorrectly, the small end of the spring faces upwards and the large end faces downwards to contact the steel ball. It is not 100% certain that the spring is placed in the correct direction. There is a phenomenon of the spring being installed in the wrong direction, resulting in unstable quality. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a spring installation error-proofing tool, which plays a role in preventing the spring installation direction from being wrong, 100% ensuring the correctness of the direction of the tapered spring being installed into the part, and eliminating the phenomenon of the spring installation direction being wrong.

[0004] The purpose of the utility model is achieved through the following technical solutions: This spring installation error-proofing tool comprises:

[0005] The anti-error plate has several blind holes evenly opened along its surface as anti-error holes. Each anti-error hole adopts an inverted cone shape with a larger top and a smaller bottom, and matches the profile of the tapered spring, so that a tapered spring is installed in each anti-error hole;

[0006] The transition plate has several blind holes evenly opened along its surface as transition holes. Each transition hole is cylindrical and the positions of the transition holes and the anti-error holes correspond one to one.

[0007] A parts positioning plate is provided with a plurality of positioning holes, each of which corresponds to a transition hole. A parts housing is placed in each positioning hole, with the inner hole of each parts housing facing upwards, and a steel ball is installed in the inner hole; and

[0008] The cover plate is used to cover the surface of the transition plate on one side of the hole. The cover plate is used to invert the transition plate and press it on the part housing to align the transition hole with the inner hole. During assembly, the cover plate is pulled out to allow the tapered springs in the transition hole to fall into the corresponding inner holes one by one and rest on the steel ball to prevent errors in spring installation.

[0009] As a further technical solution, a limit baffle is set on one side of the part positioning plate. When the transition plate is inverted on the part housing, the side walls of the cover plate and the transition plate are fitted with the limit baffle to align the transition hole with the inner hole.

[0010] The beneficial effects of the utility model are:

[0011] 1. A tapered anti-error hole is set in the anti-error plate to match the conical spring, which plays a role in preventing the spring from being installed in the wrong direction. After adopting this tooling, it can 100% effectively guarantee the correct direction of the tapered spring installed into the part, eliminate the wrong direction of the spring installation, and improve the quality stability;

[0012] 2. A limit baffle is set on one side of the part positioning plate to position the cover plate and the transition plate to prevent the transition hole from misaligning with the inner hole;

[0013] 3. A batch of springs can be assembled at one time, which is more efficient than manual installation one by one. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is a detailed introduction to the present invention with reference to the accompanying drawings:

[0031] Example: As shown in the attached Figures 5 to 14 As shown, this spring installation error-proofing tooling includes an error-proofing plate 1, an error-proofing hole 11, a transition plate 2, a transition hole 21, a cover plate 3, a part positioning plate 4, a positioning hole 41, a limit baffle 42, a part housing 5, an inner hole 51, a steel ball 6 and a tapered spring 7.

[0032] Reference Attachment Figure 5 、 6 , a total of 15 (15 in this embodiment, or other numbers) blind holes of 5×3 are evenly opened on the surface of the anti-error plate 1 as anti-error holes 11. Each anti-error hole 11 adopts an inverted cone shape with a larger upper part and a smaller lower part, and matches the profile of the tapered spring 7, so that each anti-error hole 11 can be equipped with a tapered spring 7, as shown in FIG. Figure 7 As shown, the tapered spring 7 must be placed in the anti-error hole 11 with the large end facing up and the small end facing down, otherwise it cannot be installed. Figure 8 shown.

[0033] like Figure 9 As shown, 15 blind holes (5×3) are evenly opened on the surface of the transition plate 2 as transition holes 21 . Each transition hole 21 is cylindrical, and the positions of the transition holes 21 and the anti-error holes 11 correspond one to one.

[0034] Reference Attachment Figure 13 、 14A total of 15 positioning holes 41 (or positioning grooves) in a pattern of 5×3 are provided on the upper surface of the part positioning plate 4, and each positioning hole 41 corresponds one-to-one to the transition hole 21. A part housing 5 is placed in each positioning hole 41, and the inner hole 51 of each part housing 5 faces upward, so that the steel ball 6 is placed in the inner hole 51, and the steel ball 6 falls to the bottom of the inner hole 51.

[0035] like Figure 12 、 13 As shown, the cover plate 3 can cover the surface of the opening side of the transition plate 2. The cover plate 3 is used to invert the transition plate 2 and press it on the part housing 5, so that the transition hole 21 is aligned with the inner hole 51. During assembly, the cover plate 3 is pulled out so that the tapered springs 7 in the transition hole 21 fall into the corresponding inner holes 51 one by one and rest on the steel ball 6, thereby realizing error-proof spring installation.

[0036] Preferably, if Figure 13 、 14 As shown, a limit baffle 42 is set on the left side of the part positioning plate 4. When the transition plate 2 is inverted on the part housing 5, the side walls of the cover plate 3 and the transition plate 2 are both in contact with the limit baffle 42, which can ensure that the transition hole 21 is aligned with the inner hole 51 to prevent misalignment.

[0037] Preferably, a positioning protrusion can be provided on the surface of the anti-error plate 1, and a positioning groove can be provided at a corresponding position on the surface of the transition plate 2, so as to facilitate one-to-one alignment of the anti-error hole 11 and the transition hole 21.

[0038] Working process of the utility model: Before assembly begins, first place the 15 component housings 5 ​​into the corresponding positioning holes 41 of the component positioning plate 4, and place the steel balls 6 into the corresponding inner holes 51, and then install them according to the following steps:

[0039] Step 1: If Figure 7 、 8 As shown, the tapered spring 7 is placed into the anti-error hole 11 of the anti-error plate 1 with the large end facing upward and the small end facing downward. If the tapered spring 7 is placed in the wrong direction, it will not be able to be placed in the tooling, which plays a role in preventing the spring from being installed in the wrong direction.

[0040] Step 2: If Figure 10 As shown, the transition plate 2 is placed on the error-proofing plate 1 so that the transition hole 21 is aligned with the error-proofing hole 11;

[0041] Step 3: If Figure 11 As shown, the transition plate 2 and the anti-error plate 1 are turned 180 degrees together, so that the tapered spring 7 falls into the corresponding transition hole 21;

[0042] Step 4: If Figure 12 As shown, the error prevention plate 1 is removed, and a cover plate 3 is placed on the transition plate 2;

[0043] Step 5: If Figure 13 As shown, the transition plate 2 and the cover plate 3 are flipped 180° together and placed on the component housing 5 so that the side walls of the transition plate 2 and the cover plate 3 are in contact with the limit stopper 42. Then, the cover plate 3 is removed so that the tapered springs 7 in the transition holes 21 fall into the corresponding inner holes 51 one by one and rest against the steel ball 6.

[0044] Step 6: If Figure 14 As shown, the transition plate 2 and the cover plate 3 are removed, the tapered spring 7 is installed, the spring direction error is eliminated, and the assembled parts are taken out one by one from the part positioning plate 4.

[0045] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
