Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical parts processing technology, specifically to a fixed structure for processing mechanical parts. Background Technology
[0002] Mechanical parts, also known as mechanical components, are the basic building blocks of machinery. They are indivisible individual parts that make up machines and equipment. Mechanical parts are both a discipline that studies and designs the basic mechanical components in various equipment, and a general term for parts and components.
[0003] A search revealed an existing patent (publication number: CN212095388U) that discloses a fixture for machining mechanical parts, including a placement table. The top of the placement table is provided with a clamping plate, and a sliding block is fixedly connected to the bottom of the clamping plate. A strip groove is formed on the top surface of the placement table. The number of clamping plates is set to two and they are symmetrically distributed about the center of the strip groove. The sliding block is slidably engaged with the strip groove. A sliding assembly is provided inside the placement table. A pressing assembly is fixedly connected to the top of the clamping plate. The sliding assembly includes a V-shaped rod, a transverse connecting sleeve, a first threaded rod, a first knob, a first sliding sleeve, a fixing rod, and a second sliding sleeve. The beneficial effects of this utility model are as follows: by rotating the first knob, the two clamping plates can be brought closer together to clamp the mechanical parts, making it easier for the mechanical parts to be processed to be aligned with the processing device. By rotating the second knob, the pressing block is lowered to press the mechanical parts firmly onto the placement table, making the mechanical parts more stable and secure. The above utility model makes the mechanical parts more stable and secure by pressing them horizontally and vertically. However, this device is only suitable for pressing rectangular mechanical parts and cannot press arc-shaped or circular mechanical parts. When it is necessary to press arc-shaped or circular mechanical parts, the mechanical parts may slide because the arc edge of the mechanical parts is not completely in contact with the edge of the clamping plate, which will cause the fixed position of the mechanical parts to shift, thereby reducing the clamping performance of the device.

When a rectangular part needs to be fixed, the rectangular extrusion seat 312 is used to fix the four sides of the rectangular part, and then the arc-shaped pressure plate 308 is used to fix the top of the rectangular part. When an arc-shaped part needs to be fixed, the positions of the arc-shaped pressure plate 308 and the rectangular extrusion seat 312 are interchanged. The curved pressure plate 308 fixes the side of the curved part, and the rectangular pressing seat 312 fixes the top of the mechanical part.

When it is necessary to fix a curved or circular mechanical part, the second locking seat 311 on one side of the rectangular pressing seat 312 is separated from the locking sleeve 310, thereby removing the rectangular pressing seat 312. Then, the nut 30 is rotated... 6. Separate the nut 306 from the threaded rod 307, thereby removing the arc-shaped pressure plate 308. Then, engage and fix the first locking seat 309 on one side of the arc-shaped pressure plate 308 with the locking sleeve 310. Next, fix the stud at the top of the rectangular pressing seat 312 to the nut 306. Then, start the second motor 401 and the second motor 402 respectively, so that the four arc-shaped pressure plates 308 fix the arc-shaped or circular mechanical parts around their respective sides.

When the third lead screw 402 drives the third threaded sleeve 403 to perform transmission, the third slide rod 404 slides on the rear slide groove 313 through the third threaded sleeve 403. At the same time, the third lead screw 402 drives the fourth lead screw 405 to rotate, and the fourth lead screw 405 drives the fourth threaded sleeve 406 to perform transmission, and the fourth threaded sleeve 406 drives the fourth slide rod 407 to slide on the front slide groove 313, so that the third slide rod 404 and the fourth slide rod 407 move towards or away from each other.
[0027] Working principle and usage process: First, place the workpiece on the upper end of the worktable 1. Start the first motor 201. The output end of the first motor 201 drives the first lead screw 202 to rotate. The first lead screw 202 drives the first threaded sleeve 203 to drive the first slide rod 204 to slide towards the workpiece on the right slide groove 313. The first slide rod 204 drives the right fixed plate 301 to move towards the workpiece. The right fixed plate 301 drives the right locking sleeve 310 to move towards the workpiece. The right locking sleeve 310 drives the right second locking seat 311 to move towards the workpiece. The right second locking seat 311 drives the right rectangular pressing seat 312 to move towards the workpiece. At the same time, the first lead screw 202 drives the second lead screw 202 to move towards the workpiece. The rod 205 rotates, driving the second threaded sleeve 206 via the second lead screw 205. The second threaded sleeve 206 then drives the second slide rod 207 to move towards the workpiece on the left slide groove 313. The second slide rod 207 drives the left fixing plate 301 towards the workpiece. The left fixing plate 301 then drives the left locking sleeve 310 towards the workpiece. The left locking sleeve 310 then drives the left second locking seat 311 towards the workpiece. The left second locking seat 311 then drives the left rectangular pressing seat 312 towards the workpiece. Thus, the rectangular pressing seats 312 on both sides simultaneously fix the left and right surfaces of the workpiece. Then, the second motor 401 is started, driving the third lead screw 402 to rotate via its output. The third screw 402 drives the third threaded sleeve 403 for seizing and transmission. The third threaded sleeve 403 drives the third slide rod 404 to move towards the workpiece on the rear slide groove 313. The third slide rod 404 drives the rear fixing plate 301 to move towards the workpiece. The rear fixing plate 301 drives the rear locking sleeve 310 to move towards the workpiece. The rear locking sleeve 310 drives the rear second locking seat 311 to move towards the workpiece. The rear second locking seat 311 drives the rear rectangular pressing seat 312 to move towards the workpiece. At the same time, the third screw 402 drives the fourth screw 405 to rotate. The fourth screw 405 drives the fourth threaded sleeve 406 for transmission. The fourth threaded sleeve 406 drives the fourth slide rod 407 to move on the front slide groove 313. The fourth slide rod 407 drives the front locking sleeve 310 to move towards the workpiece. The front locking sleeve 310 drives the front second locking seat 311 to move towards the workpiece. The front second locking seat 311 drives the front rectangular pressing seat 312 to move towards the workpiece.

The output end of the electric telescopic rod 303 drives the connecting seat 304 to move downward. The connecting seat 304 drives the rotating rod 305 to move downward. The rotating rod 305 drives the nut 306 to move downward.
