[0019] 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.

[0020] like Figure 1-3 As shown, a fixing device for processing a motor housing 1 comprises a base plate 14, a supporting leg 8, a workbench 9, a cylinder 12, a sleeve 11, a pull rod 4, a plurality of pressure plates 2, a plurality of connecting rods 3 and a cover plate 5. The workbench 9 is arranged on the base plate 14 through the supporting leg 8. The sleeve 11 is vertically penetrated and arranged at the center position of the workbench 9 and is vertically slidably connected to the workbench 9. A plurality of pressure plates 2 are evenly arranged and designed on the upper end surface of the sleeve 11 and are rotatably connected to the upper end surface of the sleeve 11. One end of a plurality of connecting rods 3 is rotatably connected to the center position of the pressure plate 2, and the other end is rotatably connected to the cover plate 5 near the center position. The center position of the lower bottom surface of the cover plate 5 is fixedly connected to the upper end of the pull rod 4. The cylinder 12 is fixedly arranged at the center position of the base plate 14. The telescopic end 12 extends into the sleeve 11 and is fixedly connected to the lower end of the pull rod 4. The lower end side wall of the sleeve 11 is provided with a card plate 10, and an elastic member is provided between the card plate 10 and the workbench 9; the side wall of the sleeve 11 is provided with a plurality of vertical sliding openings 6, and the workbench 9 is provided with a slide plate 7 at the position corresponding to the sliding opening 6, and the slide plate 7 is vertically slidably connected with the sliding opening 6; the elastic member is a tension spring 13, and the tension spring 13 is sleeved on the sleeve 11, and the upper end of the tension spring 13 is connected to the lower bottom surface of the workbench 9, and the lower end is connected to the card plate 10; a groove 15 matching the connecting rod 3 is provided under the cover plate 5, and when the cover plate 5 is pressed against the connecting rod 3, the connecting rod 3 can be limited to the groove 15; a rubber pad is provided on the bottom surface of the pressure plate 2.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-3 It can be seen that when the utility model is used, the telescopic end of the cylinder 12 moves upward, pushing the pull rod 4 and the cover plate 5 to move upward. Since the upper end of the connecting rod 3 is rotatably connected to the bottom surface of the cover plate 5 near the center, the lower end is rotated with the center position of the pressure plate 2, and one end of the pressure plate 2 is rotatably connected to the upper end of the sleeve 11, the connecting rod 3 and the pressure plate 2 are designed in multiple groups. The cover plate 5 moves upward to pull the connecting rod 3 and the pressure plate 2 to make the pressure plate 2 as vertical as possible. At this time, the personnel put the motor housing 1 from the cover plate 5, through the connecting rod 3, the pressure plate 2, and finally put it on the sleeve 11, and fall on the workbench 9, as shown in FIG. Figure 2As shown. It should be understood that most motor housings 1 are provided with an axial hole for installing and limiting the rotating shaft. The motor housing 1 is sleeved on the sleeve 11 with the aid of the axial hole. The diameter of the sleeve 11 is smaller than the axial hole. At this time, the telescopic end of the cylinder 12 contracts, driving the pull rod 4 and the cover plate 5 connected to the pull rod 4 to move downward, and the multiple connecting rods 3 push the multiple pressure plates 2 to diverge, that is, the pressure plate 2 rotates toward the outside of the sleeve 11. It should be noted here that an elastic member is provided between the bottom clamping plate 10 of the sleeve 11 and the workbench 9. The purpose is to enable the pull plate and the cover plate 5 to move downward so as to give priority to the movement of the connection and the pressure plate 2, rather than the sleeve 11 moving downward directly. The pressure plate 2 and the connecting rod 3 rotate until they are almost parallel to the horizontal plane, and the bottom surface of the cover plate 5 can press the connecting rod 3, which drives the sleeve 11 to move downward until the pressure plate 2 abuts against the motor housing 1. The cover plate 5 continues to move downward under the tension, and the pressing connecting rod 3 and the pressure plate 2 are pressed near the upper edge of the axial hole of the motor housing 1, as shown in FIG. Figure 1 As shown, the purpose of the pressing plate 2 pressing and fixing the motor housing 1 on the workbench 9 is achieved. Compared with the prior art, the utility model uses a cylinder 12 as a power source, has a simple structure, is easy to repair and maintain, and the outer diameter of the sleeve 11 is smaller than the shaft hole, and can be used to fix more models of motor housings 1, with stable fixation and strong applicability. It should be understood that when the pressing plate 2 is horizontal, its pressing range is larger than the inner diameter of the shaft hole of the motor housing 1, which is common knowledge among those skilled in the art.

[0023] Among them, the side wall of the sleeve 11 is provided with multiple vertical sliding openings 6, and a slide plate 7 is provided at the position of the workbench 9 corresponding to the sliding opening 6. The slide plate 7 is vertically slidably connected to the sliding opening 6. When working, the slide plate 7 is vertically slidably connected to the sliding opening 6, thereby ensuring the stability of the sleeve 11 during work, and then ensuring the overall stability and stability of the device.

[0024] Among them, the elastic part is a tension spring 13, which is sleeved on the sleeve 11. The upper end of the tension spring 13 is connected to the lower bottom surface of the workbench 9, and the lower end is connected to the clamping plate 10. The purpose is to move the pulling plate and the cover plate 5 downward to preferentially connect and move the pressure plate 2, thereby ensuring that the pressure plate 2 can abut against the motor housing 1 during the descent process.

[0025] Among them, a groove 15 matching the connecting rod 3 is arranged under the cover plate 5. When the cover plate 5 is pressed against the connecting rod 3, the connecting rod 3 can be limited to the groove 15, thereby ensuring the accuracy of the position of the connecting rod 3 and also ensuring the stability when the pressure plate 2 is pressed.

[0026] In addition, a rubber pad may be provided on the bottom surface of the pressing plate 2 to avoid damage to the motor housing 1 during the pressing and fixing process.

[0027] 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.
