Detailed Implementation
[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] like Figures 1-7 As shown, this utility model provides a technical solution: an automotive input shaft turning device, including a base 1, a clamping seat 11 fixedly mounted on the top of the base 1, a turning device 2 fixedly mounted on the top of the base 1, and further including:
[0026] The extended clamping mechanism 3 is located on the top of the base 1. The extended clamping mechanism 3 is used to provide stable support for the automotive input shaft. The extended clamping mechanism 3 includes a lateral adjustment component 31, a rotation support component 32, and a pneumatic clamping component 33.
[0027] The pneumatic clamping assembly 33 includes an annular tube 331. A support block 332 is fixedly installed on the left side of the annular tube 331. There are four support blocks 332, which are symmetrically arranged on the side of the annular tube 331. A support tube 333 is fixedly installed on the inner wall of the support block 332. A connecting tube 334 is fixedly connected to the outer wall of the annular tube 331. The end of the connecting tube 334 away from the annular tube 331 is fixedly connected to the end of the support tube 333. A square tube 335 is fixedly connected to the end of the support tube 333 away from the connecting tube 334. The end of the car input shaft is clamped at the clamping seat 11. Then, the left and right positions of the pneumatic clamping assembly 33 are adjusted so that the pneumatic clamping assembly 33 is close to the turning part of the car input shaft. Then, the pneumatic clamping assembly 33 is used to assist in clamping the car input shaft. The clamping seat 11 and the turning device 2 are then controlled to work, so that the car input shaft can be turned stably.
[0028] As one implementation method in this embodiment, such as Figure 4 , Figure 5 As shown, an elastic element 336 is fixedly connected to the inner wall of the square tube 335. An I-shaped slider 337 is fixedly connected to one end of the elastic element 336 away from the inner wall of the square tube 335. The I-shaped slider 337 is slidably connected inside the square tube 335. The end of the I-shaped slider 337 away from the elastic element 336 extends to the outside of the square tube 335 and is fixedly connected to a moving block 338. When assisting in clamping the car input shaft, high-pressure gas is injected into the inner cavity of the annular tube 331. The gas then passes through the connecting tube 334 and the support tube 333 and enters the inner cavity of the square tube 335, pushing the I-shaped slider 337. This causes the arc-shaped block 3382 to be clamped on the outer wall of the car input shaft. At the same time, the elastic element 336 is stretched. When the gas inside the annular tube 331 is discharged, the elastic element 336 pulls the I-shaped slider 337 and the arc-shaped block 3382 to reset.
[0029] As one implementation method in this embodiment, such as Figure 6 As shown, a replacement part 3381 is detachably connected to the end of the movable block 338 away from the square tube 335. An arc-shaped block 3382 is fixedly installed on the end of the replacement part 3381 away from the movable block 338. The replacement part 3381 is installed on the movable block 338 with screws. The screws are removed, and the damaged arc-shaped block 3382 can be replaced. After the replacement is completed, the screws are reset, and the installation of the arc-shaped block 3382 is completed.
[0030] As one implementation method in this embodiment, such as Figure 2As shown, the lateral adjustment assembly 31 includes a fixed base 311, which is fixedly installed on the top of the machine base 1. There are two fixed bases 311. A crossbar 312 and a crossbeam 313 are fixedly installed between the two adjacent sides of the fixed bases 311. A sliding seat 314 is slidably connected to the outer wall of the crossbar 312 and the crossbeam 313. A connecting seat 315 is fixedly installed on the top of the sliding seat 314. By sliding the sliding seat 314 left and right on the crossbar 312 and the crossbeam 313, the overall position of the pneumatic clamping assembly 33 can be adjusted, thereby adjusting the pneumatic clamping assembly 33 to be close to the turning part of the car input shaft, which facilitates the machining.
[0031] As one implementation method in this embodiment, such as Figure 2 As shown, the bottom of the sliding seat 314 is threadedly connected to a fixing bolt 316. The threaded end of the fixing bolt 316 is movably connected to the bottom of the crossbeam 313. A rotating handle 317 is fixedly installed on the outer wall of the fixing bolt 316. In the initial state, the threaded end of the fixing bolt 316 is tightly attached to the bottom of the crossbeam 313, realizing the function of fixing the sliding seat 314 on the crossbeam 313. Before adjustment, the fixing bolt 316 can be loosened, and after adjustment, the fixing bolt 316 can be tightened. The design of the rotating handle 317 makes it easy for the user to manually rotate the fixing bolt 316.
[0032] As one implementation method in this embodiment, such as Figure 3 As shown, the rotating support assembly 32 includes an annular seat 321, which is fixedly installed on the top of the connecting seat 315. An annular groove 322 is provided on the left side of the annular seat 321. A rotating annular seat 323 is rotatably connected in the inner cavity of the annular groove 322. Ball bearings 324 are provided on both the inner and outer surfaces of the rotating annular seat 323. An annular tube 331 is fixedly installed on the left side of the rotating annular seat 323. By rotating the rotating annular seat 323 in the annular groove 322, during the turning process, when the clamping seat 11 drives the car input shaft to rotate, the arc-shaped block 3382 can rotate with the car input shaft, which facilitates the machining process. The design of the ball bearings 324 improves the smoothness of the rotation of the rotating annular seat 323 in the annular groove 322.
[0033] As one implementation method in this embodiment, such as Figure 7As shown, a valve pipe 34 is fixedly connected to the outer wall of the annular pipe 331. A connector 341 is movably inserted into the end of the valve pipe 34 away from the annular pipe 331. A rubber ring 342 is fixedly fitted onto the outer wall of the connector 341. A square pipe 343 is fixedly connected to the end of the connector 341 away from the valve pipe 34. A pressure gauge 344 is fixedly connected to the outer wall of the square pipe 343. A pipe opening 345 is fixedly connected to the outer wall of the square pipe 343. A handle 346 is fixedly installed at the end of the square pipe 343 away from the connector 341. In use, pressure can be supplied to the annular pipe 331 from the valve pipe 34. The internal addition or release of gas in 31 is specifically achieved by first connecting the output pipe of the air pump to the port 345, then inserting the connector 341 into the valve pipe 34, with the rubber ring 342 sealing the connection. Simultaneously, the valve pipe 34 is opened, and the air pump is then controlled to fill the annular tube 331 with gas. The user can observe the air pressure from the pressure gauge 344. When the preset value is reached, the valve pipe 34 is closed, and then the connector 341 is removed and the air pump is turned off. The design of the handle 346 makes it convenient for the user to hold the connector 341.
[0034] Working principle: In use, the end of the car input shaft is clamped in the clamping seat 11, and then the fixing bolt 316 is loosened to adjust the left and right position of the pneumatic clamping assembly 33 so that the pneumatic clamping assembly 33 is close to the turning part of the car input shaft. Then the fixing bolt 316 is tightened, and high-pressure gas is injected into the inner cavity of the annular tube 331. The gas then passes through the connecting tube 334 and the support tube 333 and enters the inner cavity of the square tube 335 to push the I-shaped slider 337. This drives the arc block 3382 to clamp on the outer wall of the car input shaft. Then the clamping seat 11 and the turning device 2 are controlled to work, so that the car input shaft can be turned steadily.
[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
