Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a clamping device for dust explosion-proof motor processing. Background Art

[0002] Explosion-proof motors are motors that can be used in flammable and explosive places and do not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, they are also widely used in textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, medicine and other departments. Explosion-proof motors are the main power equipment and are usually used to drive pumps, fans, compressors and other transmission machinery. Explosion-proof motors use flameproof enclosures to separate electrical parts that may generate sparks, arcs and dangerous temperatures from the surrounding explosive gas mixture.

[0029] The driving assembly 31 includes a first slide groove 311 and an upper clamping block 323. The first slide groove 311 is opened at the top of the placement plate 2. A first connecting hole 312 is opened on the left side of the first slide groove 311. A second connecting hole 313 is opened on the right side of the first slide groove 311. A bidirectional threaded rod 314 is rotatably connected to the first connecting hole 312. A first motor 315 is fixedly connected to the right side of the placement plate 2. A threaded hole 317 is opened on the right side of the upper clamping block 323 corresponding to the bidirectional threaded rod 314.

[0030] The output shaft of the first motor 315 is inserted into the second connecting hole 313, and the output end of the first motor 315 is fixedly connected to the right end of the bidirectional threaded rod 314. The surface of the bidirectional threaded rod 314 is symmetrically rotatably connected to the lower clamping block 316 through the threaded hole 317. Since the bottom end of the lower clamping block 316 is rectangular and the slide groove is also rectangular, the rotation of the bidirectional threaded rod 314 will cause the two lower clamping blocks 316 to move toward each other.

[0031] The auxiliary clamping assembly 32 includes a connecting block 321, which is fixedly connected to the top of the lower clamping block 316. A second sliding groove 322 is provided on the right side of the connecting block 321. An upper clamping block 323 is slidably connected in the second sliding groove 322. A sliding hole 324 is provided on the top of the upper clamping block 323. A guide rod 325 is fixedly connected to the top and bottom of the second sliding groove 322. A spring 326 is sleeved on the surface of the guide rod 325 between the top of the second sliding groove 322 and the upper clamping block 323.

[0032] The upper clamping block 323 is slidably connected to the surface of the guide rod 325 through the sliding hole 324, the top of the spring 326 is fixedly connected to the top of the second slide groove 322, and the bottom of the spring 326 is fixedly connected to the top of the upper clamping block 323.

The upper clamping block 323 assists in clamping the motor through the elastic force of the spring 326, so that the motor is more stable during processing. Example

[0033] See also Figure 4-5 , and on the basis of the first embodiment, an angle adjustment mechanism 4 is further obtained.

[0034] The angle adjustment mechanism 4 includes a fixed block 41, which is fixedly connected to the top of the base 1. A second motor 42 is fixedly connected to the top of the fixed block 41, and a worm 43 is fixedly connected to the output end of the second motor 42. A bearing 44 is fixedly connected to the top of the base 1, a shaft 45 is fixedly connected to the inner wall of the bearing 44, and a worm gear 46 is fixedly connected to the middle of the surface of the shaft 45. A support rod 48 is fixedly connected to the bottom of the placement plate 2 near the edge, and a rectangular groove 49 is provided on the surface of the support rod 48 near the bottom end, a connecting rod 411 is fixedly connected in the rectangular groove 49, and a roller 412 is fixedly connected to the surface of the connecting rod 411. An annular groove 47 is provided on the top of the base 1.

[0035] The worm 43 is meshed with the worm wheel 46, the top end of the shaft 45 is fixedly connected to the bottom of the placement plate 2, the bottom end of the support rod 48 is inserted into the annular groove 47, and the surface of the roller 412 contacts the bottom of the annular groove 47. The support rod 48 can support the placement plate 2 to prevent the placement plate 2 from tilting, and the roller 412 provided at its bottom can make the placement plate 2 rotate more smoothly.

[0036] In actual operation, when the device is used, the dust explosion-proof motor is placed in the middle of the placement plate 2, and the first motor 315 is started. The operation of the first motor 315 causes the bidirectional threaded rod 314 to rotate. The rotation of the bidirectional threaded rod 314 causes the two lower clamping blocks 316 to move toward each other to clamp the dust explosion-proof motor. The upper clamping block 323 moves downward due to the elastic force of the spring 326, thereby completing the clamping and fixing of the dust explosion-proof motor. The clamping of the dust explosion-proof motor by the lower clamping block 316 and the upper clamping block 323 makes the dust explosion-proof motor more stable, which is convenient for processing.

[0037] The operation of the second motor 42 can cause the worm 43 to rotate. Since the worm 43 is meshed with the worm wheel 46, the worm wheel 46 can be rotated. The rotation of the worm wheel 46 can cause the shaft 45 to rotate, thereby rotating the placement plate 2. The rotation of the placement plate 2 completes the angle adjustment of the dust-proof explosion-proof motor without the need for staff to move back and forth. The support rod 48 at the bottom of the base plate supports the placement plate 2 to prevent the placement plate 2 from tilting due to the weight of the dust-proof explosion-proof motor. The roller 412 at the bottom end slides in the annular groove 47, which can make the placement plate 2 rotate more smoothly.
