[0057] It should be noted that the cross-sectional dimension of the assembling channel 10 can be less than or equal to the cross-sectional dimension of the circlip 310 under no external force, so as to fix the circlip 310 in the assembling channel 10, according to the different shapes of the circlip 310, the cross-section of the assembling channel 10 can be circular, square or other shapes, which is not limited in the present application.

[0058] It should be noted that the cross-sectional dimension of the assembling channel 10 can be gradually reduced, gradually increased or not changed along the assembling direction of the circlip 310, which is not limited in the present application.

[0059] The opening hole 20 can penetrate through the loading tool 100, or can not penetrate through the loading tool 100, that is, the opening hole 20 can be arranged only at the inlet of the assembling channel 10, the shape of the opening hole 20 can be rectangular, circular or other shapes, which is not limited in the present application.

[0060] In addition, the extending direction of the assembling channel 10 can be the assembling direction of the circlip 310.

[0062] In some embodiments of the present application, as shown in Figure 5 and Figure 6 The loading tool 100 includes oppositely arranged first wall surface 11 and second wall surface 12, the first wall surface 11 is provided with a first opening 21, the second wall surface 12 is provided with a second opening 22, the assembling channel 10 is in communication with the first opening 21 and the second opening 22; the opening hole 20 is in communication with the first opening 21 along the first wall surface 11 and extends to the second opening 22 of the second wall surface 12.

[0063] It should be noted that the opening hole 20 extends from the first opening 21 to the second opening 22, that is, the opening hole 20 penetrates through the peripheral wall surface of the assembling channel 10.

[0064] Thus, the opening 20 is communicated with the first opening 21 along the first wall surface 11 and extends to the second wall surface 12 and the second opening 22, the movement state of the circlip 310 in the assembly channel 10 can be observed, when the position of the circlip 310 deviates, it can be adjusted in time to avoid misplacement of the circlip 310.

[0065] In some embodiments of the present application, the cross section of the assembly channel 10 is an arc of a circle.

[0066] It should be noted that the cross section of the assembly channel 10 is an arc of a circle, the notch of the arc of a circle is the opening 20, and the chord length of the arc of a circle is the width of the opening 20.

[0067] In this way, the cross section of the assembly channel 10 is set as an arc of a circle, that is, the edge of the opening 20 of the feeding tool 100 is in a contracted posture, and the edge of the opening 20 of the feeding tool 100 can limit the circlip 310 to avoid falling off of the circlip 310 during assembly.

[0068] In some embodiments of the present application, as shown in Figure 5 The feeding tool 100 includes an assembly part 30 and a limiting part 40, the assembly part 30 is provided with the assembly channel 10 and the opening 20, and the limiting part 40 is connected to the outer periphery of the assembly part 30, and the opening 20 penetrates the limiting part 40.

[0069] The limiting part 40 can be a limiting protrusion, a limiting sphere or a limiting ring, which is not limited in the present application.

[0070] In this way, the assembly channel 10 and the opening 20 are provided on the assembly part 30, the circlip 310 can be assembled to the air spring assembly 300 through the assembly channel 10 and the opening 20, the limiting part 40 is connected to the outer periphery of the assembly part 30, and the limiting part 40 can limit the assembly part 30 during assembly of the circlip 310 to avoid shaking of the assembly part 30 and ensure precise assembly of the circlip 310.

[0071] For example, the assembly part 30 is in a cylindrical shape, the limiting part 40 is a limiting ring arranged around the outer periphery of the assembly part 30, the opening 20 penetrates the limiting ring, the limiting part 40 has a first tangent plane, the assembly part 30 has a second tangent plane, and the first tangent plane and the second tangent plane are coplanar with the plane where the opening 20 is located.

[0072] In this way, the first tangent plane and the second tangent plane are coplanar with the plane where the opening 20 is located to form a larger operation space at the opening 20, which facilitates workers to place the circlip 310 in the feeding tool 100, and when the feeding tool 100 is processed, the first tangent plane and the second tangent plane can be formed by cutting along the opening 20 in the plane, which facilitates processing of the feeding tool 100.

[0073] In some embodiments of the present application, as shown in Figure 5 A guide slope 13 is arranged at the first opening 21, and the size of the guide slope 13 gradually decreases along the first direction, which is the direction from the first wall 11 to the second wall 12.

[0074] It should be noted that the size of the guide slope 13, i.e. the area surrounded by the guide slope 13 in the first plane perpendicular to the first direction, is greater than or equal to the size of the circlip 310 at the maximum, and is less than or equal to the size of the circlip 310 at the minimum, which is not limited in the present application.

[0075] In this way, the guide slope 13 is arranged at the first opening 21, and the size of the guide slope 13 gradually decreases along the first direction, so that the circlip 310 can be directly placed at the guide slope 13 when assembling the circlip 310, and the circlip 310 can be shrunk until it moves to the circlip mounting position of the air spring assembly 300 by pushing the circlip 310 along the first direction by the assembly tool 200, without the need for workers to compress the circlip 310 in advance and place it in the assembly channel 10, thereby reducing the assembly steps and improving the assembly efficiency.

[0076] In some embodiments of the present application, as shown in Figure 5 and Figure 7 The feeding tool 100 includes a guide piece 50 protruding from the second wall 12, and the guide piece 50 has an extension channel 51 formed therein and communicating with the assembly channel 10, and the radial size of the assembly channel 10 is consistent with the radial size of the extension channel 51.

[0077] It should be noted that the cross-sectional size of the extension channel 51 can be less than or equal to the cross-sectional size of the circlip 310 to fix the circlip 310 in the extension channel 51, and the cross-section of the extension channel 51 can be circular, square or other shapes according to the shape of the circlip 310, which is not limited in the present application.

[0078] The guide piece 50 can be cylindrical, prismatic or other shapes, which is not limited in the present application.

[0079] In addition, the opening 20 can or can not pass through the guide piece 50, which is not limited in the present application.

[0080] In this way, the guide 50 protrudes from the second wall surface 12, and when the snap ring 310 is assembled, the guide 50 can be inserted into the air spring assembly 300, and an extension channel (51) is formed in the guide 50 and communicates with the assembly channel 10, so that the snap ring 310 moves to the air spring assembly 300 through the assembly channel 10 and the extension channel (51) to complete the assembly, avoiding the misalignment of the feeding tool 100 and the air spring assembly 300, which causes the snap ring 310 to be unable to be normally installed. The radial dimension of the assembly channel 10 is consistent with the radial dimension of the extension channel (51), so that the snap ring 310 can move more smoothly in the assembly channel 10 and the extension channel (51).

[0081] In some embodiments of the present application, as shown in Figure 5 and Figure 7 The radial dimension of the outer peripheral wall of the guide 50 gradually decreases along the first direction.

[0082] In the present application, the radial dimension of the outer peripheral wall of the guide 50 can be less than or equal to the radial dimension of the outer peripheral wall of the limiting piece 40, which is not limited in the present application.

[0083] In this way, by gradually reducing the radial dimension of the outer peripheral wall of the guide 50 along the first direction, the size of the end of the guide 50 away from the assembly piece 30 can be minimized, so that the guide 50 can be more easily inserted into the air spring assembly 300, and the feeding tool 100 can be guided to cooperate with the air spring assembly 300 to complete the assembly of the snap ring 310.

[0084] For example, the air spring assembly 300 includes a bearing mounting groove 330 and a valve mounting hole 340, the valve mounting hole 340 is arranged on the bottom wall surface of the bearing mounting groove 330, and the bearing mounting groove 330 and the valve mounting hole 340 are coaxially arranged, the snap ring mounting position is arranged on the inner peripheral wall surface of the valve mounting hole 340, the guide 50 is conformally arranged with the valve mounting hole 340, and the limiting piece 40 is conformally arranged with the bearing mounting groove 330.

[0085] In this way, when the snap ring 310 is assembled, the outer peripheral wall surface of the guide 50 is in contact with the inner peripheral wall surface of the valve mounting hole 340, and the outer peripheral wall surface of the limiting piece 40 is in contact with the inner peripheral wall surface of the bearing mounting hole, so as to limit the guide 50 and the limiting piece 40, and further limit the feeding tool 100, avoiding the feeding tool 100 from shaking when the snap ring 310 is assembled, which causes the snap ring 310 to be misaligned.

[0086] In some embodiments of the present application, as shown in Figure 4 and Figure 8As shown, the grabbing assembly 220 comprises a plurality of clamping jaws 240, which are arranged around the through hole and movably connected with the base 210. The clamping jaw 240 comprises a supporting portion 241, an extruding portion 242 and a clamping portion 243. The supporting portion 241 is rotatably connected with the base 210, and the clamping jaw 240 can rotate around the supporting portion 241. The extruding portion 242 is connected with one side of the supporting portion 241, and an elastic member 244 is arranged on the side of the extruding portion 242 away from the through hole, so that the extruding portion 242 is in contact with the pushing assembly 230. The clamping portion 243 is connected with the other side of the supporting portion 241, so that when the pushing assembly 230 extrudes the extruding portion 242, the clamping portion 243 moves towards the through hole.

[0087] It should be noted that the plurality of clamping jaws 240 can comprise two clamping jaws 240, three clamping jaws 240 or four clamping jaws 240, etc., which are not limited in the present application.

[0088] The pushing assembly 230 can further comprise an outer pushing head and an inner pushing head. The outer pushing head is in a cylindrical shape, and the inner pushing head is in a cylindrical shape. The inner pushing head is arranged in the outer pushing head. When the outer pushing head is not in contact with the extruding portion 242, the grabbing assembly 220 is in the first posture. When the outer pushing head extrudes the extruding portion 242 and the elastic member 244, the grabbing assembly 220 is in the second posture, so as to grab the feeding tool 100.

When the pushing assembly 230 pushes, the extruding portion 242 is first contacted, so that the extruding portion 242 and the clamping portion 243 rotate around the supporting portion 241. The extruding portion 242 moves away from the through hole, and the clamping portion 243 moves towards the through hole to perform a contraction clamping action to clamp the feeding tool 100. Then, the pushing assembly 230 pushes the snap spring 310 in the feeding tool 100 to be assembled to the snap spring mounting position of the air spring assembly 300. In this way, the pushing assembly 230 can control the grabbing assembly 220 to clamp the feeding tool 100 while pushing the snap spring 310, so as to improve the working efficiency of the assembly tool 200.

[0091] In some embodiments of the present application, as shown in FIG. 6, the pushing assembly 230 can further comprise a pushing rod 231 and a pushing head 232. The pushing rod 231 is arranged in the pushing head 232, and the pushing head 232 is arranged in the outer pushing head. Figure 8As shown, the assembly tool 200 further comprises a limiting seat 250 connected to the base 210, when the grabbing assembly 220 is in the second posture, the limiting seat 250 is in contact with the first wall surface 11 of the feeding tool 100.

[0092] Wherein, the limiting seat 250 can be arranged at the inner side of the clamping part 243, when the grabbing assembly 220 grabs the feeding tool 100, the limiting seat 250 is not in contact with the first avoiding part, and the plurality of clamping claws 240 clamps the assembly part 30.

[0093] Therefore, when the grabbing assembly 220 is in the second posture, the limiting seat 250 is in contact with the first wall surface 11 of the feeding tool 100, when the assembly tool 200 grabs the feeding tool 100, the limiting seat 250 can limit the first direction of the feeding tool 100, so that the grabbing assembly 220 can be stably clamped at the preset position of the feeding tool 100, and the circlip 310 in the feeding tool 100 can be more stably assembled to the air spring assembly 300.

[0094] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
