Description

Technical Field

[0001] The utility model relates to the technical field of motor housing processing, in particular to a motor housing clamping device. Background Art

[0002] As an important power source of modern industry, motors are widely used in various mechanical equipment and power systems. In the manufacturing process of motors, the packaging of motor housings is a crucial link. The motor housings not only protect the electrical components, electronic components and mechanical components inside the motors, but also affect the heat dissipation performance, protection level and overall safety and stability of the motors. In the process of motor housing production and processing, the motor housings are usually required to be clamped and fixed to facilitate the staff to perform processing operations on the motor housings. However, the traditional motor housing clamping device has many shortcomings in practical applications. For example, since the overall shape of the motor housing is cylindrical, it is difficult to achieve accurate positioning and stable fixation of the motor housing during the clamping process. At the same time, there are heat dissipation fins distributed on the surface of the motor housing. During the clamping process, the clamping mechanism will directly contact and clamp the heat dissipation fins on the motor housing. Since the clamping requires a certain amount of force, the heat dissipation fins will be damaged during clamping, which can easily cause the heat dissipation fins to deform and become skewed, reducing the product quality. This not only affects the processing accuracy of the motor housing, but also may cause safety hazards during the processing process. Therefore, it is necessary to design a motor housing clamping device. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a motor housing clamping device proposed by the utility model includes a support frame 1, a movable frame 2 and a clamping mechanism 3. The movable frame 2 is slidably installed on the inner side of the support frame 1. The support frame 1 and the movable frame 2 are slidably installed through a slide groove 101. A slider 201 matching the slide groove 101 is fixedly installed on the surface of the movable frame 2, so that the slider 201 can slide up and down along the slide groove 101, so that the movable frame 2 can stably move up and down vertically. A bidirectional screw rod 103 is rotatably installed on one side of the support frame 1, and a driving motor 102 corresponding to the bidirectional screw rod 103 is fixedly installed on the top of the support frame 1. The output end of the driving motor 102 is fixedly connected to the bidirectional screw rod 103, and the bidirectional screw rod 103 is threadedly connected to the movable frame 2 through a threaded sleeve 202. The bidirectional screw rod 103 can be driven to rotate by driving the motor 102, and the two-way thread on the bidirectional screw rod 103 can drive the two threaded sleeves 202 to move relative to each other, and the movable frame 2 can be driven to move relative to each other. The bottom of the movable frame 2 is provided with a clamping mechanism 3, which can drive the clamping mechanism 3 to close, and the motor housing can be clamped and fixed. The bottom of the support frame 1 is fixedly installed with a base 5, and the top structure can be conveniently supported by the base 5, so that it is convenient to place it in a suitable position for use. A collecting groove 501 is provided on the top of the base 5, and the collecting groove 501 corresponds to the clamping mechanism 3. During the processing of the motor housing, the generated debris can fall into the collecting groove 501 for collection, which is convenient for the staff to perform recycling operations;

[0022] The clamping mechanism 3 includes a limit frame 301, a movable column 302, a first clamping plate 303, a second clamping plate 304 and a first thrust spring 305. The limit frame 301 is fixedly connected to the movable frame 2, and the movable column 302 is slidably installed at the bottom of the limit frame 301. The clamping mechanism 3 also includes a moving block 306 and a moving groove 307. The limit frame 301 and the movable column 302 are slidably installed through the moving block 306. The bottom of the limit frame 301 is provided with a moving groove 307 that cooperates with the moving block 306, so that the moving block 306 can slide along the moving groove 307, so that the movable column 302 can move horizontally. The bottom of the movable column 302 is movably installed with the first clamping plate 303 through an active joint, and the second clamping plate 304 is movably connected between the first clamping plate 303 and the second clamping plate 304 through a rotating shaft. The shape of the clamping plate 304 has a certain curvature, and the first clamping plate 303 and the second clamping plate 304 can move together to form an opening and closing effect. When the motor housing is clamped, the first clamping plate 303 and the second clamping plate 304 can move accordingly, so that the first clamping plate 303 and the second clamping plate 304 can adapt to the surface curvature of the motor housing, and the motor housing can be clamped more accurately, thereby improving the firm effect during clamping and avoiding the situation of falling off. A first thrust spring 305 is fixedly connected between the second clamping plate 304 and the limiting frame 301. When the clamping of the motor housing is released, the second clamping plate 304 can be pushed downward by the first thrust spring 305, so that the second clamping plate 304 and the first clamping plate 303 are opened outward, which can facilitate the next clamping operation of the motor housing.

[0023] The inner walls of the first clamping plate 303 and the second clamping plate 304 are both provided with a pile clamping mechanism 4, which includes a limit block 401, an extrusion block 402, a second thrust spring 403 and a movable groove 404. The limit block 401 is fixedly connected to the first clamping plate 303 and the second clamping plate 304. The limit block 401 is slidably installed on both sides of the limit block 401 through the movable groove 404, so that the limit block 401 can slide inside the movable groove 404. The second thrust spring 403 is fixedly connected between the limit block 401 and the movable groove 404. When clamping the motor housing, the limit block 401 can be inserted between the gaps of the cooling fins on the surface of the motor housing. Through the thrust of the second thrust spring 403, the extrusion block 402 can be squeezed and limited on both sides of the cooling fins, and can be supported and limited in the gaps of the cooling fins on the motor housing, which can avoid the cooling fins from being skewed during clamping and effectively protect the cooling fins from being damaged. At the same time, the limiting effect of the cooling fins on the limit block 401 can be utilized to avoid the motor housing from rotating during the clamping process, thereby effectively enhancing the clamping effect.

[0024] The working principle of the motor housing clamping device based on the embodiment is: by placing the device in a suitable position for use, placing the motor housing between the clamping mechanisms 3, and driving the bidirectional screw rod 103 to rotate by driving the motor 102, the threaded sleeve 202 can be used to drive the two moving frames 2 to move together, and the clamping mechanism 3 can be driven to close and clamp the motor housing. When clamping, the first clamping plate 303 and the second clamping plate 304 can move accordingly, and can fit according to the curvature of the motor housing surface, so that the motor housing can be clamped and fixed more accurately. During the clamping process, the limit block 401 can be inserted into the gap of the heat dissipation fins on the surface of the motor housing, so that the extrusion block 402 can fit on both sides of the heat dissipation fins. Through the thrust of the second thrust spring 403, the extrusion block 402 can limit and support both sides of the heat dissipation fins, which can effectively reduce the skewness and damage of the heat dissipation fins caused by clamping the motor housing, making it convenient for the staff to perform processing operations on the motor housing, and the debris generated during processing can fall into the collection groove 501 below for collection, and the debris can be scattered on the ground and difficult to clean.
