Detailed implementation manners

[0027] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0028] As Figure 1 shown, a bushing pressing machine for a vehicle axle main beam includes a machine body 1. A support platform 2 is arranged on the side of the machine body 1. A lifting drive device 3 is arranged above the support platform 2. Lifting support devices 4 are arranged on both sides of the lifting drive device 3. A first clamping device 5 is slidably connected to both sides of the machine body 1. A second clamping device 6 is slidably connected above the lifting drive device 3. The workpiece is placed on the lifting support device 4. The first clamping device 5 is arranged on one side of the workpiece, and the second clamping device 6 is arranged on the other side of the workpiece. By the mutual cooperation of the first clamping device 5 and the second clamping device 6, the left and right sides of the workpiece are clamped and fixed, thereby improving the accuracy of bushing installation. At the same time, the clamping distance can be adjusted accordingly according to the size of the workpiece, which has a wide application range and is convenient to use.

[0029] Specifically, as Figure 2 shown, fixed seats 101 are arranged on both sides above the machine body 1. A sliding groove 1011 is arranged on the side of the fixed seat 101. The first clamping device 5 includes a first cylinder 501. The cylinder rod of the first cylinder 501 is connected with a first clamping member 502. The first clamping member 502 is slidably connected to the sliding groove 1011. The telescopic movement of the cylinder rod of the first cylinder 501 will drive the first clamping member 502 to slide back and forth on the sliding groove 1011.

[0030] As Figures 3 to 5As shown in the figure, the lifting drive device 3 includes a support frame body 301 and a lifting plate 302. A handwheel 303 is arranged on the side of the support frame body 301. The handwheel 303 is connected to a first lead screw 304. The first lead screw 304 is connected to a first lead screw nut seat 305. Two sides below the first lead screw nut seat 305 are provided with first sliders 306. The first sliders 306 are slidably connected to a first linear guide 307. The first linear guide 307 is fixedly arranged on a support plate 315. Two sides of the first lead screw 304 are provided with first mounting seats 308. Two sides of the first lead screw nut seat 305 are hinged with first telescopic members 309. Two sides of the first mounting seats 308 are hinged with second telescopic members 310. The middle parts of the first telescopic member 309 and the second telescopic member 310 are cross-hinged. The end of the first telescopic member 309 is hinged with a second mounting seat 311. The second mounting seat 311 is fixedly arranged below the lifting plate 302. The end of the second telescopic member 310 is hinged with a third mounting seat 312. Above the third mounting seat 312 is provided with a second slider 313. The second slider 313 is slidably connected to a second linear guide 314. The second linear guide 314 is fixedly arranged below the lifting plate 302. Rotating the handwheel 303 will drive the first lead screw 304 to rotate. The rotation of the first lead screw 304 will drive the first lead screw nut seat 305 to slide back and forth on the first linear guide 307 through the first slider 306. When the first lead screw nut seat 305 moves forward, it will simultaneously drive the first telescopic rod 309 and the second telescopic rod 310 to expand laterally outward from the middle hinge point, thereby driving the lifting plate 302 to move downward. When the first lead screw nut seat 305 moves backward, it will simultaneously drive the first telescopic rod 309 and the second telescopic rod 310 to contract laterally inward from the middle hinge point, thereby driving the lifting plate 302 to move upward. In this way, the lifting and moving of the second clamping device 6 is realized.

[0031] Sliding cylinders 316 are arranged around the support plate 315. A sliding rod 317 is slidably connected in the sliding cylinder 316. The end of the sliding rod 317 is fixedly arranged on the lifting plate 302. When the lifting plate 302 moves up and down, the sliding rod 317 will slide up and down in the sliding cylinder 316 accordingly. This design can make the lifting of the lifting plate 302 more stable and effectively prevent the lifting plate 302 from tilting.

[0032] The second clamping device 6 includes a second lead screw 601. The second lead screw 601 is connected to a second lead screw nut seat 602. Above the second lead screw nut seat 602 is provided with an adjusting clamping assembly 603. Two sides below the adjusting clamping assembly 603 are provided with a plurality of third sliders 604. The third sliders 604 are slidably connected to a third linear guide 605. The third linear guide 605 is fixedly arranged on the lifting plate 302. The motor drives the second lead screw 601 to rotate. The second lead screw 601 drives the second lead screw nut seat 602 to move back and forth. The second lead screw nut seat 602 drives the adjusting clamping assembly 603 to move back and forth.

[0033] As Figure 6As shown in the figure, the adjusting clamping assembly 603 includes an adjusting base 6031. Above the adjusting base 6031, there is a screw rod 6032. The screw rod 6032 is threadedly connected to a second clamping member 6033. On both sides below the second clamping member 6033, there are several fourth sliders 6034. The fourth sliders 6034 are slidably connected to a fourth linear guide 6035. The fourth linear guide 6035 is fixedly arranged on the adjusting base 6031. Rotating the screw rod 6032 can drive the second clamping member 6033 to slide left and right on the fourth linear guide 6035 through the fourth sliders 6034, thereby adjusting the position where the second clamping member 6033 presses against the workpiece.

[0034] As Figures 7 to 8 As shown in the figure, the lifting and supporting device 4 includes a fixed frame body 401. Inside the fixed frame body 401, there is a second cylinder 402. The cylinder rod of the second cylinder 402 is connected to a supporting assembly 403. The supporting assembly 403 includes a supporting frame body 4031. The supporting frame body 4031 is rotatably connected with a first rolling roller 4032 and a second rolling roller 4033. The workpiece is placed above the first rolling roller 4032 and the second rolling roller 4033. When the cylinder rod of the second cylinder 402 extends and retracts, it will drive the supporting assembly 403 to move up and down, thereby realizing the lifting operation of the workpiece.

[0035] Working principle: First, place the workpiece on the first rolling roller 4032 and the second rolling roller 4033. Drive the workpiece to rise to the processing position through the second cylinder 402. Then rotate the handwheel 303 to raise the second clamping device 6 to the clamping position. The second clamping device 6 is activated to drive the second clamping member 6033 to move forward. While tightly positioning one side of the workpiece, the first clamping device 5 pushes the first clamping member 502 backward to tightly position the other side of the workpiece, so as to facilitate the processing of the workpiece and improve the processing accuracy. When the workpiece is processed, the second clamping device 6 is activated to drive the second clamping member 6033 to move backward, and at the same time, the first clamping device 5 pushes the first clamping member 502 forward to release the clamping state of the workpiece. The second cylinder 402 drives the workpiece to rise again to facilitate the unloading of the workpiece.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
