Detailed Description

As shown in the figure, the machine shell riveting device for micro-motor production comprises a base 101, wherein support columns 106 are symmetrically and fixedly installed on the base 101 through pin joints, a support 109 is fixedly installed at the upper end of each support column 106 through pin joints, a hydraulic cylinder 110 is fixedly installed on each support 109, the hydraulic cylinder 110 is connected with a piston rod, one end of the piston rod extends to the lower portion of the support 109, and one end of the piston rod extending to the lower portion of the support 109 is fixedly installed with an installation plate 107. The hydraulic cylinder 110 can drive the piston rod to drive the mounting plate 107 to move linearly in the up-and-down direction. The mounting plate 107 is fixedly provided with a riveting head mounting seat 300 through bolt connection, and in order to avoid that the mounting plate 107 drives the riveting head 108 on the riveting head mounting seat 300 to move over a limit, a limit buffer mechanism is arranged between the base 101 and the bracket 109. Specifically, the limiting buffer mechanism comprises a limiting column 102 symmetrically and fixedly mounted on the base 101 through a pin joint, a guide column 103 is fixedly mounted at the upper end of the limiting column 102 through welding, and the upper end of the guide column 103 is fixedly connected with the lower end of the bracket 109 through the pin joint. A limiting cylinder 105 is slidably sleeved on the guide post 103, a first spring 104 is sleeved on the guide post 103 between the limiting cylinder 105 and the limiting post 102, and one side of the limiting cylinder 105 is fixedly connected with a mounting plate 107 through welding. When the mounting plate 107 moves downwards, the limiting cylinder 105 moves downwards together to compress the first spring 104, the first spring 104 can play a buffering role, and the limiting column 102 plays a limiting role to prevent the riveting head mounting base 300 and the riveting head 108 mounted on the mounting plate 107 from moving over the limit.

The rivet head mounting seat 300 includes a mounting seat body 301 fixedly mounted on the mounting plate 107 by bolting, the mounting seat body 301 is provided with a step slide groove 302, and a buffer seat 305 is slidably mounted in the step slide groove 302. A guide rod is fixedly arranged at the bottom of the stepped sliding groove 302 through welding, a second spring 303 is sleeved on the guide rod, and one end of the guide rod is inserted into a guide groove 304 arranged on the buffer seat 305. A limit snap ring 307 is fixedly mounted on the mounting base 301 positioned at the notch of the step slide groove 302 through bolt connection.

An insert block 306 is arranged at the end of the buffer seat 305 away from the guide rod, and a corresponding slot 111 is arranged on the riveting head 108. During installation, the riveting head 108 is inserted into the buffer seat 305 from the axial through hole of the limit snap ring 307, and then is fixed through bolt connection or pin connection. When the riveting head 108 contacts the workpiece, the riveting head 108 pushes the buffer base 305 to move upwards, and the second spring 303 is compressed. The second spring 303 provides a cushion to protect the rivet head 108.

In order to enable the device to process micro-motors with different shapes, the micro-motors with different shapes are effectively fixed, and a micro-motor fixing seat 200 is installed on the base 101 below the riveting head 108. Specifically, the micro-motor fixing seat 200 includes a chuck body 201, the chuck body 201 is a solid body in the middle, a plurality of movable jaws are radially installed on the chuck body 201, each movable jaw includes a sliding block 204 installed on the chuck body 201 in a sliding manner and a lead screw 206 installed at the lower end of the sliding block 204, and a rectangular groove 205 is formed on the outer end face of the lead screw 206. The lead screw 206 can be screwed clockwise or counterclockwise by inserting the four-corner protrusion into the four-corner groove 205, and the rotating lead screw 206 drives the sliding block 204 to move towards the heart direction or the centrifugal direction. The sliding block 204 of the movable jaw is fixedly provided with an air cylinder 202, the air cylinder 202 is connected with a piston rod, and the stroke of the piston rod is small. Therefore, the initial position of each air cylinder 202 can be manually and independently adjusted through the movable clamping jaws, and then the air cylinders 202 drive the piston rods to drive the clamping blocks arranged on the piston rods to clamp the micro-motor. So that micro-motors of different specifications can be clamped. In order to avoid the damage of the micro-motor body caused by the clamping block, the clamping block is made of soft materials such as rubber. In the same way, a rubber cushion 203 is arranged in the middle of the upper end surface of the chuck body 201, and anti-skid grains are arranged on the rubber cushion 203. During processing, the micromotor can be placed on the rubber cushion 203, so that the body of the micromotor is protected.
