[0002] With the continuous improvement of science and technology, mechanized production has gradually replaced manual production of products. Mechanized production cannot be separated from the power provided by motors. Motors refer to electromagnetic devices that realize electrical energy conversion or transmission based on the law of electromagnetic induction. However, the current motor housings are complex in shape and difficult to process. During the processing of motor housings, the housings need to be fixed by special clamping devices. The existing housings are fixed directly by limiting blocks for compression and limiting. The sides of the housings are not fixed, and the clamping tooling needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to provide a motor housing clamping tool to solve the problems raised in the above background technology.

[0004] The purpose of this utility model can be achieved through the following technical solutions:

[0005] A motor housing clamping tool comprises a push frame, a pressure plate, a pin shaft, a return spring, a side clamping seat and a swing arm rod. An inner groove is opened in the middle position of one side of the push frame, a pressure plate is movably provided inside the inner groove, a rubber pad is provided on the outer surface of the pressure plate, pin shafts are provided at both ends of the push frame, and rotating seats are movably installed at both ends of the push frame through the pin shafts. One side of the rotating seat is connected to the swing arm rod, and one end of the swing arm rod is connected to the side clamping seat.

[0006] In the above-mentioned motor housing clamping tool, a pressing groove is provided inside the side pressing seat, and an anti-slip pad is provided inside the pressing groove.

[0007] In the above-mentioned motor housing clamping fixture, both ends of the pressing plate are connected to connecting rods, and one end of the connecting rod is connected to a toothed plate.

[0008] In the above-mentioned motor housing clamping fixture, a gear ring is sleeved on the exterior of the rotating seat, and the inner side of the gear plate is meshedly connected with the surface of the gear ring.

[0009] In the above-mentioned motor housing clamping tool, two guide rods are connected to the inner side of the pressure plate, one end of the guide rod is movably connected to the push frame, and a return spring is provided inside the inner groove, and the return spring is sleeved on one end of the guide rod.

[0010] In the above-mentioned motor housing clamping fixture, a pushing cylinder is provided on one side of the pushing frame, an output end of the pushing cylinder is connected to a push rod, and one end of the push rod is connected to one side of the middle portion of the pushing frame.

[0011] Compared with the prior art, the advantages of the motor housing clamping fixture of the utility model are:

[0012] The present application provides a movable pressure plate inside the push frame, and both ends of the pressure plate are connected to side clamping seats through connecting rods. When the motor housing needs to be clamped, the push frame is pushed toward the workpiece by pushing the cylinder, and the pressure plate contacts the workpiece and clamps the pressure plate. At the same time, the pressure plate moves toward the rear side of the inner groove. When the pressure plate moves, the tooth plate can be driven to move by the connecting rod, and the tooth plate directly engages with the rotating seat, thereby driving the rotating seat to rotate, so that the swing arm rod outside the rotating seat drives the side clamping seat to swing inward, so that the side clamping seat is pressed against the side of the workpiece. In this way, the end of the workpiece is squeezed and clamped by the pressure plate, and the side is limited by the side clamping seat. In this way, the workpiece clamping stability is better.

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] A motor housing clamping tooling includes a push frame 1, a pressure plate 3, a pin shaft 5, a return spring 6, a side clamping seat 8 and a swing arm rod 9. An inner groove 2 is opened in the middle position of one side of the push frame 1, and a pressure plate 3 is movably arranged inside the inner groove 2. A rubber pad 4 is provided on the outer surface of the pressure plate 3. Pin shafts 5 are provided at both ends of the push frame 1. Rotating seats 14 are movably installed at both ends of the push frame 1 through the pin shaft 5. One side of the rotating seat 14 is connected to the swing arm rod 9, and one end of the swing arm rod 9 is connected to the side clamping seat 8.

[0019] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model is a motor housing clamping tool. Specifically, a pressing groove 7 is opened inside the side pressing seat 8, and an anti-slip pad is provided inside the pressing groove 7.

[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a motor housing clamping tool. Specifically, both ends of the pressure plate 3 are connected to the connecting rod 11, and one end of the connecting rod 11 is connected to the tooth plate 10. The tooth plate 10 is an existing disclosed metal tooth plate 10 structure.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a motor housing clamping tool. Specifically, the outer portion of the rotating seat 14 is provided with a gear ring, and the inner side of the gear plate 10 is meshed with the surface of the gear ring.

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a motor housing clamping tool. Specifically, two guide rods 12 are connected to the inner side of the pressure plate 3, one end of the guide rod 12 is movably connected to the push frame 1, and a return spring 6 is provided inside the inner groove 2. The return spring 6 is sleeved on one end of the guide rod 12. The return spring 6 is an existing disclosed spring structure. Mainly when the push frame 1 is released, the pressure plate 3 can automatically move toward the outside. In this way, the tooth plate 10 can be driven to slide toward the outside, so that the rotating seat 14 rotates again, and the swing arm rod 9 drives the side clamping seat 8 to open toward both sides.

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a motor housing clamping tool. Specifically, a pushing cylinder 13 is provided on one side of the pushing frame 1, the output end of the pushing cylinder 13 is connected to a push rod, and one end of the push rod is connected to the middle side of the pushing frame 1. The pushing cylinder 13 is a public electric cylinder structure, which is mainly powered by an external power supply.

[0024] When the workpiece is pressed, the motor housing is placed between the two symmetrically arranged push frames 1, and then the push cylinders 13 are used to push the push frames 1 toward the workpiece. The pressure plate 3 on the inner side of the push frame 1 first contacts the workpiece, and the pressure plate 3 presses the workpiece. At the same time, the pressure plate 3 moves toward the rear side of the inner groove 2. When the pressure plate 3 moves, the tooth plate 10 can be driven to move by the connecting rod 11. The tooth plate 10 directly engages with the tooth ring on the surface of the rotating seat 14, and then drives the rotating seat 14 to rotate, so that the swing arm rod 9 on the outer side of the rotating seat 14 drives the side pressure seat 8 to swing inward, so that the side pressure seat 8 is pressed against the side of the workpiece. In this way, the end of the workpiece is squeezed and pressed by the pressure plate 3, and the side of the workpiece can also be limited by the side pressure seat 8. In this way, the workpiece clamping stability is better.
