[0020] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0021] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0022] Figure 1-3 It includes a dividing table 10, a turntable 20, a weight reduction hole 21, a positioning tool 30, a notch 31, a wire pressing robot 40, a stationary plate 50, a first pressing plate 60, a second pressing plate 70, an upper cover material taking robot 80, a push cylinder 81, a lifting cylinder 82, a clamping cylinder 83, a hydraulic buffer 84, a solenoid valve island 90, etc.

[0023] like Figure 1-3 As shown, the utility model is a turntable structure for assembling a muffler upper cover, comprising a turntable 20 driven by a dividing table 10, and a stationary disk 50 is fixedly arranged on the inner ring of the turntable 20.

[0024] At least four positioning fixtures 30 are evenly arranged on the upper surface of the rotating disk 20 in a circular shape to position the upper cover of the muffler, and the first pressing plate 60, the second pressing plate 70, the steel wire pressing robot 40, and the upper cover material taking robot 80 are installed on the stationary disk 50 at intervals of 90 degrees along the circumference. In specific production practice, 8 positioning fixtures 30 are evenly arranged on the rotating disk 20 along the circumference.

[0025] The first pressing plate 60 and the second pressing plate 70 extend radially to the top of the positioning fixture 30, and avoidance holes are respectively provided at the pressing ends of the first pressing plate 60 and the second pressing plate 70. In order to facilitate the external auxiliary hot riveting structure to perform reliable hot riveting operation on the product through the avoidance holes during operation, and the first pressing plate 60 and the second pressing plate 70 can prevent the product from being brought out.

[0026] The upper cover material taking robot 80 comprises a horizontal push cylinder 81 , which is mounted on the stationary plate 50 , a lifting cylinder 82 is mounted on the piston rod end of the horizontal push cylinder 81 , and a clamping cylinder 83 is mounted on the piston rod end of the lifting cylinder 82 .

[0027] A positioning groove is provided on the positioning fixture 30 to position the upper cover of the muffler.

[0028] Furthermore, a notch 31 is provided on the outer side of the upper end of the positioning tool 30 corresponding to the positioning groove, and the notch 31 can be used to manually assist in taking and placing the upper cover of the muffler, which is convenient for operation.

[0029] The stationary plate 50 is provided with a solenoid valve island 90, which controls the movement of the push cylinder 81, the lifting cylinder 82 and the clamping cylinder 83. The solenoid valve island 90 is a mature product in the prior art, and is a control component composed of a plurality of solenoid valves.

[0030] Furthermore, since the diameter of the turntable 20 is relatively large, the moment of inertia of the turntable 20 is relatively large when it is working, which inevitably requires a larger load on the dividing table 10. For this reason, a plurality of weight-reducing holes 21 are evenly distributed in a circular shape on the turntable 20 to achieve the effect of reducing weight.

[0031] like Figure 3As shown, during operation, since the extension and retraction of the horizontal push cylinder 81 is very fast and has a large impact force, in order to reduce the impact force, a buffering effect is played; hydraulic buffers 84 are respectively installed on both sides of the horizontal push cylinder 81 to achieve buffering when the lifting cylinder 82 returns horizontally. Further, the hydraulic buffer 84 is installed on a buffer mounting bracket, and the buffer mounting bracket is fixed on the stationary plate 50, and the horizontal push cylinder 81 passes through the through hole of the buffer mounting bracket.

[0032] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
