Description

Technical Field

[0001] The utility model belongs to the technical field of double-chamber air spring pistons, and in particular relates to an automatic ring welding workstation. Background Art

[0002] The dual-chamber air spring piston assembly includes a piston housing, a piston base and a solenoid valve seat. The piston housing and the piston base are formed by spinning and secondary stamping and heating forging, and the solenoid valve seat is formed by hot forging to ensure the stability of the entire structure. The solenoid valve seat is located on one side of the circumference of the base body, and is equipped with synchronous bolts. The bottom end of the piston housing is aligned with the top end of the piston base and welded.

[0003] like Figure 1 As shown, in the assembly of the piston housing, the piston base and the solenoid valve seat, the housing base of the piston housing is welded to the piston base, the waist block of the adjustable waistline mechanism of the piston is welded to the housing base, and the piston base is welded to the valve mounting seat of the solenoid valve seat. In the traditional technology, the welding between the waist block, the piston housing and the piston base is carried out separately, and three welding workstations are required to complete the welding operation of the dual-chamber air spring piston assembly. The welding process needs to be carried out by three workstations separately, so the efficiency is low, and it may take a long time to complete the assembly and welding work. At the same time, more welding workers or automated welding robots are required to perform this work, and the labor cost may increase. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides an automatic ring welding workstation.

It can ensure that the valve mounting seat is firmly fixed in the correct position on the locker D, thereby improving the assembly accuracy.

[0017] Compared with the prior art, the technical effects and advantages of the utility model are: the automatic ring welding workstation automatically clamps, fixes and positions the various components in the dual-chamber air spring piston assembly through the clamping parts A and the clamping parts B, and there is no need to separately position and weld the various components in the air chamber air spring piston assembly, which saves assembly time, reduces the demand for operators, reduces labor costs, and improves production efficiency.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The following is combined with Figure 2-4 To further explain this application in detail,

[0027] The embodiment of the present application discloses an automatic ring welding workstation, comprising a clamping piece A1, a clamping piece B8 and a push cylinder 11, wherein the clamping piece A11 is used to clamp and fix the waist block 2, the piston housing 3 and the piston base 4, and one end of the clamping piece A1 is clamped and fixed by an electric chuck A7 driven by a reduction motor 6;

[0028] The clamping piece B8 is used to clamp and fix the valve mounting seat 5, and one end of the clamping piece B8 is clamped and fixed by an electric chuck B10 rotating on the base B9;

[0029] The piston rod of the push cylinder 11 pushes the clamping part B8 and the valve mounting seat 5 toward the clamping part A1, so that the valve mounting seat 5 is docked with the piston base 4 to achieve the clamping and positioning of the dual-chamber air spring piston assembly by the clamping part A1 in cooperation with the clamping part B8.

[0030] This automatic ring welding workstation clamps and fixes each component through the clamp A1 and the clamp B8, and then pushes the clamp B8 and the valve mounting seat 5 toward the clamp A1 by pushing the piston rod of the cylinder 11, so that the valve mounting seat 5 is docked with the piston base 4, thereby realizing the assembly and positioning of the double-chamber air spring piston assembly. The double-chamber air spring piston assembly can be directly positioned during the assembly of the piston housing 3, the piston base 4 and the solenoid valve seat through the clamp A and the clamp B8. Therefore, the double-chamber air spring piston assembly that has been positioned and fixed can be directly used in conjunction with the welding robot for ring welding operations. There is no need to separately perform the welding between the waist block 2, the piston housing 3 and the piston base 4. One workstation is used to replace the three workstations of the traditional process, which reduces manual operation and conversion time, thereby improving production speed and efficiency, reducing dependence on operators, and reducing labor costs. The automated clamping and pushing process can provide more precise component alignment, improve assembly accuracy, and reduce the need for welding workstations.

[0031] By means of the electric chuck driven by the reduction motor 6 and the piston rod of the push cylinder 11, the automatic clamping, fixing and pushing operation of the dual-chamber air spring piston assembly is realized. Since the sizes of the waist-shaped block 2, the piston housing 3 and the piston base 4 are gradually increased, the clamping part A1 can be inserted between the waist-shaped block 2, the piston housing 3 and the piston base 4, and the clamping part A1 is used to clamp and fix the waist-shaped block 2, the piston housing 3 and the piston base 4, thereby improving the clamping and positioning efficiency of the dual-chamber air spring piston assembly.

[0032] The center of the electric chuck A7 and the center of the electric chuck B10 are on the same axis.

[0033] The reduction motor 6 is fixed on the base A12, the electric chuck A7 is rotatably connected to the base A12, and the base A12 is fixed on the base 14 on the top of the welding table 13. The reduction motor 6 drives the electric chuck A7 and the clamp A1 to rotate to drive the waist block 2, the piston housing 3 and the piston base 4 to rotate to cooperate with the welding robot to complete the ring welding action of the double-chamber air spring piston assembly.

[0034] By driving the electric chuck A7 through the reduction motor 6, the rotation speed of the waist block 2, the piston housing 3 and the piston base 4 can be accurately controlled to ensure the stability and consistency of the welding process. The reduction motor 6 and the electric chuck are combined with the clamping piece A1 and the base A12 to realize the fully automatic ring welding clamping action, reduce manual intervention, and improve production efficiency. The reduction motor 6 and the electric chuck are integrated on the base A12, which has a compact structure, simple operation, and is easy to maintain and manage. By accurately controlling the rotation speed, the stability and consistency of the welding quality can be ensured, and the occurrence of welding defects can be reduced. The rotation driven by the reduction motor 6 can realize rotation at different speeds and directions, which is suitable for the ring welding operation of the double-chamber air spring piston assembly.

[0035] A guide rail 15 is provided on the top of the welding table 13, and a sliding support 16 at the bottom of the base B9 slides in cooperation with the guide rail 15. The push cylinder 11 is fixed on the electric cylinder bracket 17 on the top of the welding table 13, and the piston rod end of the push cylinder 11 is fixedly connected to the base B9.

[0036] Through the design of the guide rail 15 and the sliding support 16, it can be ensured that the base B9 can move smoothly and accurately on the welding table 13, thereby achieving accurate docking between the valve mounting seat 5 and the piston base 4, thereby improving assembly accuracy. This design simplifies the operation process. The assembly positioning can be achieved by only pushing the base B9 through the piston rod of the push cylinder 11. The operation is simple and quick. Fixing the push cylinder 11 on the electric cylinder bracket 17 can save space and make the structure of the welding workstation more compact.

[0037] The clamping part A1 includes a shaft A101 clamped by an electric chuck A7, a limit plate A102 fixed on the shaft A101 and limited by the waist block 2, and a connecting frame A106 connecting the shaft A101, the limit plate A102, the locker A103, the locker B104, and the locker C105;

[0038] The locker A103 is used to lock the waist block 2, the locker B104 is used to lock the piston housing 3, and the locker C105 is used to lock the piston base 4.

[0039] Through the special lockers A103, B104 and C105, the waist-shaped block 2, piston housing 3 and piston base 4 can be firmly locked in the correct position to improve the assembly accuracy. Different lockers are used to lock different components to ensure that the components in the clamp A1 are firmly fixed and not easy to move or loosen. The components are connected by the connecting frame A106 to complete the fixation of the waist-shaped block 2, piston housing 3 and piston base 4 at one time, saving assembly time and improving production efficiency.

[0040] The clamping part B8 includes a shaft rod B801 clamped by an electric chuck B10, a limit plate B802 fixed on the shaft rod B801 and cooperating with the valve mounting seat 5 to limit the position, and a connecting frame B804 connecting the limit plate B802 and the locker D803, wherein the locker D803 is used to lock the valve mounting seat 5.

[0041] Through the cooperation of the electric chuck B10 and the limit plate B802, the valve mounting seat 5 can be firmly fixed in the correct position on the locker D803, thereby improving the assembly accuracy. The limit plate B802 and the connecting frame B804 fix the valve mounting seat 5 on the shaft rod B801, thereby ensuring that it is firmly fixed and not easy to move or loosen. The shaft rod B801 is clamped by the electric chuck B10, which is easy and quick to operate. The design of the connecting frame B804 and the limit plate B802 can make the structure of the clamp B8 compact and easy to install and operate.

[0042] The automatic ring welding workstation clamps and fixes each component through clamping parts A and clamping parts B, and then pushes clamping parts B and valve mounting seats toward clamping parts A through the piston rod of the push cylinder, so that the valve mounting seat and the piston base are docked, thereby realizing the assembly positioning of the double-chamber air spring piston assembly. The valve mounting seat can be directly clamped as a whole, and the ring welding operation can be performed in conjunction with the welding robot. It does not require the coordination of multiple ring welding workstations, which can greatly improve production efficiency and reduce production costs.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
