DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example

[0027] like Figure 1-3 As shown, a welding fixture for a solenoid valve mounting plate and an oil storage barrel for a variable damping shock absorber described in this embodiment includes a base plate fixing part 10, a fixed base plate 20, a first semicircular sleeve 30, a second semicircular sleeve 40, a first clamping part 50, a second clamping part 60, a positioning pin 70 and a synchronous pulley 80. The base plate fixing part 10 is rotatably connected to the fixed base plate 20, and a synchronous pulley 80 is connected to one side of the fixed base plate 20. A first semicircular sleeve 30 for clamping the oil storage barrel is slidably provided at the middle position of the fixed base plate 20, a second semicircular sleeve 40 is provided on one side of the oil storage barrel on the fixed base plate 20, and the second semicircular sleeve 40 is used for clamping the solenoid valve mounting plate, a positioning pin 70 for limiting the position of the oil storage barrel is provided at the middle position of the fixed base plate 20, a second clamping part 60 for clamping the oil storage barrel is provided on the fixed base plate 20, and a first clamping part 50 for clamping the solenoid valve mounting plate is provided on the fixed base plate 20.

[0028] There may be errors in the manufacturing of the solenoid valve mounting plate and the oil storage barrel. In order to ensure that the solenoid valve mounting plates and oil storage barrels of different size precisions can be clamped normally, an adjustable clamping kit is used. The two coaxial first semicircular sleeves 30 can be adjusted according to the length of the oil storage barrel. When the diameter of the oil storage barrel changes, the first semicircular sleeve 30 can be removed and replaced to ensure that solenoid valve mounting plates and oil storage barrels of different sizes can be processed on a fixed base plate 20; if the same batch of solenoid valve mounting plates and oil storage barrels are processed, after one clamping is completed, you only need to mark the position of the positioning part to facilitate quick clamping next time.

[0029] like Figure 4 As shown, the first clamping member 50 includes a first placement seat 51, a first telescopic rod 52, a first contraction spring 53 and a first right-angle fixing rod 54. The first placement seat 51 is bolted to the fixed base plate 20. The first telescopic rod 52 is provided on the side wall of the first placement seat 51. The first right-angle fixing rod 54 is vertically fixed to the end of the first telescopic rod 52. A first contraction spring 53 is provided between the first right-angle fixing rod 54 and the first placement seat 51 and located on the outside of the first telescopic rod 52.

[0030] The first contraction spring 53 can pull the first right-angle fixing rod 54 so that the end of the first right-angle fixing rod 54 limits the position of the solenoid valve mounting plate; the first right-angle fixing rod 54 can be adjusted according to the size of the solenoid valve mounting plate until it is adjusted to a suitable size for better use effect.

[0031] like Figure 5 As shown, the second clamping member 60 includes a second placement seat 61, a second contraction spring 62, a second telescopic rod 63 and a second right-angle fixing rod 64. The second placement seat 61 is bolted to the fixed base plate 20. A second telescopic rod 63 is provided on the top of the second placement seat 61. A second right-angle fixing rod 64 is vertically fixed to the top of the second telescopic rod 63. A second contraction spring 62 is provided between the second placement seat 61 and the second right-angle fixing rod 64 and located on the outside of the second telescopic rod 63.

[0032] The second contraction spring 62 can pull the second right-angle fixing rod 64, so that the end of the second right-angle fixing rod 64 limits the position of the oil storage barrel; the second right-angle fixing rod 64 can be adjusted according to the size of the oil storage barrel until it is adjusted to a suitable size, which has a better limiting effect on the oil storage barrel.

[0033] like Figure 6 As shown, a first slot 23 connected to the first semicircular sleeve 30 is symmetrically provided at the middle position of the fixed base plate 20, and the first semicircular sleeve 30 slides in the first slot 23 to adjust the position of the first semicircular sleeve 30 on the fixed base plate 20. A second slot 24 connected to the second clamping member 60 is provided on the fixed base plate 20, and the second clamping member 60 slides in the second slot 24 to adjust the position of the second clamping member 60 on the fixed base plate 20. A fourth slot 26 connected to the first clamping member 50 is provided on the fixed base plate 20, and the first clamping member 50 is located in the fourth slot 26 to slide and adjust the position of the first clamping member 50 on the fixed base plate 20.

[0034] This structural arrangement allows the positions of the first clamping member 50, the second clamping member 60 and the first semicircular sleeve 30 to be adjusted, and can achieve a better position limiting effect on the solenoid valve mounting plate and the oil storage barrel.

[0035] like Figure 6 As shown, a third slot 25 is provided on the fixed base plate 20 between the second semicircular sleeve 40 and the first slot 23 , and the third slot 25 is for a welding gun to pass through.

[0036] The tops of both ends of the fixed bottom plate 20 are symmetrically fixed with arc-shaped fixing blocks 21 , and the outer walls of the arc-shaped fixing blocks 21 are fixed with rotation connecting shafts 22 , which are connected to the bottom plate fixing member 10 .

[0037] The bottom plate fixing member 10 includes a fixed base 11 , a support plate 12 and a fixed bearing 13 . The support plates 12 are fixed to the tops of both ends of the fixed base 11 . The support plates 12 are provided with fixed bearings 13 connected to the rotating connecting shaft 22 .

[0038] like Figure 7-8 As shown, the synchronous pulley 80 is composed of a pulley 81 and a synchronous belt 82 . The pulley 81 is fixedly connected to the rotating connecting shaft 22 , and the synchronous belt 82 is sleeved on the pulley 81 .

[0039] The two coaxial first semicircular sleeves 30 and the positioning pins 70 limit the six degrees of freedom of the oil storage barrel, the second semicircular sleeve 40 limits the four degrees of freedom of the solenoid valve mounting plate, and the end of the solenoid valve mounting plate limits its axial freedom on the end surface of the first semicircular sleeve 30. The solenoid valve mounting plate and the oil storage barrel are clamped separately by two clamping parts to ensure that the two are in an accurate position relative to the welding gun during welding.

[0040] The power transmission route of the clamp is: the external motor drives the synchronous belt 82 to rotate, thereby driving the pulley 81 to rotate, so that the fixed base plate 20 rotates accordingly, which is convenient for welding the solenoid valve mounting plate and the oil storage barrel.

[0041] It should be noted that, in this article, if there are first and second, etc., relational terms are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
