Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a fixing device used for processing a supercharger housing. Background Art

[0002] The shape of the supercharger housing is relatively irregular, so it is difficult to fix it during its processing. The most common way is to design a cylinder clamping assembly at the corresponding position on the workbench according to the model and specifications of the housing, and use the cylinder to drive the pressure plate to clamp and fix the edge of the housing flange.

[0003] However, the fixing device of the prior art usually has a set of cylinder clamping assemblies corresponding to one type of shell, which is highly targeted and less versatile. When it is necessary to fix other types of supercharger shells, due to the different shapes and sizes of different types of shells, personnel are required to reset the position of the cylinder clamping assembly on the workbench and adjust its angle at the same time. The adjustment and replacement are troublesome and affect work efficiency. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a fixing device for supercharger housing processing, which can adjust the position and angle of the pressing end of the pressing plate through the rotational connection between the limit plate and the sleeve and the rotating shaft, and the horizontal sliding connection between the pressure plate and the limit plate. The adjustment is simple, convenient and quick, thereby achieving the purpose of fixing the edges of housings of different models and improving applicability.

[0007] Preferably, the lower end of the limiting rod is configured to be cone-shaped.

[0008] Preferably, a rubber pad is provided at the bottom of the pressing plate.

[0009] The utility model provides a fixing device for processing a supercharger housing, which has the following beneficial effects:

[0010] 1. The utility model adjusts the position and angle of the pressing end of the pressing plate by the rotational connection between the limit plate and the sleeve and the rotating shaft, and the horizontal sliding connection between the pressing plate and the limit plate.

[0017] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0018] According to the instruction manual Figure 1-2 It can be known that when the utility model is working, the supercharger housing 14 is placed on the workbench 13. Since the sleeve 3 is rotatably connected to the rotating shaft 11 connected to the telescopic end of the cylinder 12, each pair of limit plates 2 is fixedly connected to the sleeve 3 and slidably connected to the pressure plate 1. Therefore, the pressure plate 1 can rotate around the axis of the rotating shaft 11. Since the sleeve 3 passes through the sliding opening 4 on the pressure plate 1, the limit plate 2 is horizontally slidably connected to the sliding groove on the pressure plate 1, so the pressure plate 1 can also move horizontally relative to the limit plate 2. The personnel adjust the pressure plate 1 to align the alignment clamping assembly with the flange hole 15 of the housing 14. The telescopic end of the cylinder 12 shrinks, driving the pressure plate 1 to move downward, and the pressure plate 1 is clamped and fixed to the flange hole 15 of the housing 14. Compared with the prior art, the utility model adjusts the position and angle of the pressing end of the pressing plate 1 through the rotation connection between the sleeve 3 and the rotating shaft 11, and the horizontal sliding connection between the pressing plate 1 and the limiting plate 2. The adjustment is simple, convenient and fast, thereby achieving the purpose of fixing the edges of the shells 14 of different models, and improving the applicability.

[0019] Among them, the alignment limit assembly includes a limit rod 9, a tension spring 5 and a clamping plate 8. The limit rod 9 is vertically movable and passes through one side of the pressure plate 1. The clamping plate 8 is fixedly arranged on the upper end of the limit rod 9. The tension spring 5 is sleeved on the limit rod 9. The upper end of the tension spring 5 is connected to the clamping plate 8, and the lower end is connected to the upper surface of the pressure plate 1.

[0020] During operation, the personnel adjust the position of the pressure plate 1 so that the limiting rod 9 is aligned with the flange hole 15 of the shell 14, and the limiting rod 9 is inserted into the flange hole 15, and then the cylinder 12 is started to drive the pressure plate 1 to move downward to clamp and fix the position. During the downward movement of the pressure plate 1, the lower end of the limiting rod 9 is squeezed and stops moving downward, and the tension spring 5 is stretched. The function of the tension spring 5 is to pull the card plate 8 and the limiting rod 9 to a lower position, first align with the flange hole 15, and then not affect the clamping work during the subsequent clamping of the pressure plate 1. The function of the limiting rod 9 is: on the one hand, it has an alignment function to facilitate the position and angle adjustment of the pressure plate 1, and on the other hand, the limiting rod 9 inserted into the jack can limit the horizontal direction of the shell 14 and improve the stability of the fixation. Of course, the bottom of the limiting rod 9 can also be designed into a cone shape 6, which can be suitable for the insertion of flange holes 15 of different sizes. Although the limiting rod 9 can move in the axial direction, the component force in the horizontal direction can also increase the stability of the shell 14 in the horizontal direction.

[0021] A rubber pad 7 is provided at the bottom of the pressing plate 1 to increase the friction between the pressing plate 1 and the housing 14, making the fixation more stable.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
