[0029] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.
[0030] like Figures 1 to 3 As shown, a riveting device 10 integrating a parts assembly process is used to be installed on a riveting press 30, which includes a loading assembly 100 and a punch head 200. The loading assembly 100 includes a base 110, a closing block 120, a supporting column 130 and an elastic member 140. The base 110 is arranged on the riveting press 30, and a sliding cavity 1111 is opened in the base 110. The closing block 120 is arranged at the opening of the sliding cavity 1111. The closing block 120 is used to support the sleeve 21. The supporting column 130 is slidably arranged in the sliding cavity 1111, and the supporting column 130 is penetrated by the closing block 120. The elastic member 140 is located at The elastic member 140 is in the sliding cavity 1111, and the elastic member 140 is respectively in contact with the supporting column 130 and the bottom wall of the sliding cavity 1111, the elastic member 140 is used to push the supporting column 130 so that one end of the supporting column 130 extends from the closing block 120, the supporting column 130 is used to pass through the spring 23 and support the sealing cover 24 and the copper sleeve 22, the punching head 200 is arranged on the riveting machine 30, and the punching head 200 is located above the supporting column 130, the punching head 200 is used to press the copper sleeve 22 so that the copper sleeve 22 is inserted into the sleeve shell 21, so that the closing block 120 squeezes the bottom end of the copper sleeve 22 toward the direction of the supporting column 130.
[0031] It should be noted that the base 110 and the stamping head 200 are both installed on the riveting press 30, and the stamping head 200 is located above the base 110. Further, a sliding cavity 1111 is formed in the base 110, the closing block 120 is installed at the opening of the sliding cavity 1111, one end of the material supporting column 130 is slidably installed in the sliding cavity 1111, and the other end of the material supporting column 130 passes through the closing block 120 and extends from above the closing block 120. The elastic member 140 is installed in the sliding cavity 1111. In one embodiment, the elastic member 140 is a helical spring structure, and the elastic member 140 is used to abut against the material supporting column 130 and the inner bottom wall of the sliding cavity 1111 respectively. Thus, under the elastic thrust of the elastic member 140, the material supporting column 130 has a tendency to extend from the top surface of the closing block 120. Thus, in use, the sleeve 21 is first sleeved on the outside of the material supporting column 130 and placed on the closing block 120, then the spring 23 is sleeved on the top of the material supporting column 130, then the sealing cover 24 is placed on the top of the spring 23, and finally the copper sleeve 22 is sleeved on the outside of the sealing cover 24 and the spring 23, thus completing the feeding. Then the riveting press 30 drives the stamping head 200 to descend, so that the stamping head 200 pushes the copper sleeve 22 to descend. At this time, the spring 23 will be compressed first. Until the sealing cover 24 abuts against the material supporting column 130, the copper sleeve 22, the sealing cover 24, and the material supporting column 130 descend synchronously. When the sleeve 22 passes through the sleeve 21, the copper sleeve 22 and the sleeve 21 are assembled. Finally, the bottom end of the copper sleeve 22 contacts the closing block 120, and the closing block 120 squeezes the bottom end of the copper sleeve 22 towards the material supporting column 130, that is, the bottom end of the copper sleeve 22 shrinks, so that the copper sleeve 22 confines the spring 23 inside. Thus, the assembly of the buffer valve is completed. Since the insertion of the copper sleeve 22 and the sleeve 21 and the riveting of the copper sleeve 22 to confine the spring 23 and the sealing cover 24 inside the copper sleeve 22 are integrated in two assembly processes, compared with the existing distributed assembly method, the assembly process can be reduced, thereby reducing the production cost and shortening the product production cycle.
[0032] As Figure 2 shown, in one embodiment, a through hole is formed in the closing block 120, and the material supporting column 130 passes through the through hole. Specifically, the through hole is located at the axial center of the closing block 120. Thus, the closing block 120 stably supports the sleeve 21.
[0033] As Figure 2 and Figure 4 shown, in one embodiment, an outwardly expanding inclined wall 122 is formed at one end of the through hole away from the sliding cavity 1111, and the outwardly expanding inclined wall 122 is used to squeeze the bottom end of the copper sleeve 22. Thus, by forming the outwardly expanding inclined wall 122, the end of the through hole has a trumpet-shaped structure. When the bottom end of the copper sleeve 22 contacts the outwardly expanding inclined wall 122, the bottom end of the copper sleeve 22 can be closed.
[0034] AsFigure 4 As shown in the figure, in one embodiment, an avoidance groove 123 is further formed on a side surface of the closing block 120 away from the sliding cavity 1111, and the avoidance groove 123 is used to support the sleeve 21.
[0035] In this way, through the formed avoidance groove 123, the lower edge of the sleeve 21 is received in the avoidance groove 123, so as to ensure that the sleeve 21 is stably placed on the closing block 120.
[0036] As Figure 3 and Figure 4 shown, in one embodiment, a clamping block 150 is provided at one end of the material supporting column 130 located in the sliding cavity 1111, and the clamping block 150 is in clearance fit with the sliding cavity 1111.
[0037] In this way, the diameter of the clamping block 150 is larger than that of the material supporting column 130, and the clamping block 150 will be stuck at the bottom of the closing block 120 to ensure that the material supporting column 130 does not slide out of the closing block 120. In one embodiment, the clamping block 150 and the material supporting column 130 are of an integrally formed structure.
[0038] As Figure 4 shown, in one embodiment, a material clamping step 131 is provided on the outer side wall of the material supporting column 130, and the material clamping step 131 is used to support the spring 23. In this way, the spring 23 is supported by the material clamping step 131 to ensure that the spring 23 is stably placed on the top end of the material supporting column 130.
[0039] As Figure 2 shown, in one embodiment, the stamping head 200 includes a stamping block 210 and an adjusting sleeve 220. The stamping block 210 is arranged on the riveting machine 30, the adjusting sleeve 220 is screwed on the outer side wall of the stamping block 210, the adjusting sleeve 220 is used to abut against the base 110, and the stamping block 210 is used to press the copper sleeve 22.
[0040] It should be noted that in order to accurately adjust the closing degree of the lower end of the copper sleeve 22, the above adjustable structure is provided. Specifically, the stamping block 210 is fixedly installed on the riveting machine 30, and the adjusting sleeve 220 is sleeved on the outer side wall of the stamping block 210. In this way, by rotating the adjusting sleeve 220, the relative position of the adjusting sleeve 220 and the stamping block 210 is adjusted. When the stamping head 200 descends, since the adjusting sleeve 220 is used to abut against the base 110, if the position of the adjusting sleeve 220 relative to the stamping block 210 changes, it means that the position of the stamping block 210 relative to the base 110 changes, so that the descending height of the copper sleeve 22 pushed by the stamping block 210 changes relative to the base 110, and the closing block 120 and the base 110 are of a fixed installation structure, that is, the descending height of the copper sleeve 22 changes relative to the closing block 120. In this way, it can be ensured that the closing accuracy of the lower end of the copper sleeve 22 can meet the predetermined requirements.
[0041] As Figure 2 shown, in one embodiment, a pressing screw 230 is screwed on the side wall of the adjusting sleeve 220, and one end of the pressing screw 230 abuts against the stamping block 210. In this way, the position between the adjusting sleeve 220 and the stamping block 210 can be locked by the pressing screw 230.
[0042] As Figure 2 shown, in one embodiment, the base 110 includes a base body 111 and a cover 112. The sliding cavity 1111 is located in the base body 111, and the cover 112 is buckled on the base body 111 so that the cover 112 and the base body 111 jointly clamp the closing block 120. Specifically, the cover 112 is locked and fixed on the base body 111 by bolts, so that the cover 112 and the base body 111 jointly clamp and fix the closing block 120.
[0043] As Figure 3 shown, in one embodiment, the riveting press 30 includes a machine table 31 and a stamping driving member 32 arranged above the machine table 31. The base 110 is arranged on the machine table 31, and the stamping head 200 is arranged on the stamping driving member 32.
[0044] It should be noted that the base 110 is installed on the machine table 31. Further, the stamping driving member 32 is one of a hydraulic cylinder or a pneumatic cylinder, and the stamping head 200 is driven by the stamping driving member 32 to move up and down.
[0045] The above embodiments only represent several embodiments of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
