[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figure 1-7 As shown, a painting device for axle production includes a primary transmission member 1, one end of which is equipped with a transition conversion member 2 for transferring axles to be painted, and the end of the transition conversion member 2 facing away from the transmission member is equipped with a stabilizing clamping device 3 for stabilizing the axles to be painted, and a spraying chamber 4 is installed on the front end of the stabilizing clamping member, and a plurality of spray nozzles are installed on the left and right inner walls of the spraying chamber 4 at equal intervals. First, after the axle to be painted is placed on the primary transmission member 1, the primary transmission member 1 is used to transmit the paint to the rear end, and after reaching a position opposite to the transition conversion member 2, the axle placed on the axle to be painted is transferred to the stabilizing clamping device 3 through the transition conversion member 2. After completing clamping on the stabilizing clamping device 3, it enters the spraying chamber 4 for spraying, thereby completing the painting operation of the axle;

[0037] The primary transmission component 1 includes a base frame 11, and a number of equidistantly installed support frames 12 are installed at the upper end of the base frame 11. Auxiliary rollers 13 for driving the axle to be painted to move in a single direction are installed between adjacent support frames 12. The spacing between the auxiliary rollers 13 is smaller than the spacing between the two support frames 12. A buckling track 14 that is arranged in accordance with the sliding member 22 is installed between the auxiliary rollers 13 and the support frames 12. The structural height of the combination of the buckling track 14 and the sliding member 22 is equal to the roller surface height of the auxiliary roller 13, and the height of the support frame 12 is less than the height of the auxiliary roller 13.

[0038] The transition conversion member 2 includes a lifting frame 21. The lifting frame 21 in this embodiment is specifically a lifting platform commonly used in existing engineering projects.

The sliding rail 221 is arranged in an I-shape, and a transition rail 222 for transitionally supporting the axle to be painted is installed on the sliding rail 221. The transition rail 222 and the sliding rail 221 are combined into a rectangular shape. The transition rail 222 is powered by a screw rod installed in the sliding rail 221 between the sliding rails 221. The screw rod is embedded in the sliding rail 221. The screw rod is threadedly connected to the sliding guide rail, and a driving motor is installed on one end of the screw rod.

Therefore, in specific use, the lifting frame 21 is first raised to a height until it is adapted to the height of the primary transmission member 1, and then the controller controls the driving motor, and the driving motor drives the screw rod to rotate. On the basis of the screw rod being threadedly connected to the sliding guide rail after rotation, the sliding guide rail gradually moves toward the primary transmission member 1 and extends into the primary transmission member 1, thereby transferring the axle to be painted on the primary transmission member 1, first transferring the axle on the primary transmission member 1 to the lifting frame 21, and the controller controls the lifting frame 21 to descend until it is adapted to the height of the stabilizing clamping device 3, thereby completing the position transfer of the axle to be painted.

[0039] The stabilizing clamping device 3 includes a stabilizing platform 31, and a connecting rail 32 is installed on the upper end of the stabilizing platform 31. The structural height of the connecting rail 32 after being combined with the sliding member 22 is equal to the retraction height of the lifting frame 21. Two clamping members 33 for clamping the axle are installed symmetrically on the left and right of the stabilizing frame.

In this embodiment, the driving part 337 specifically includes an internal gear slidably mounted on the slide 331, the internal gear is meshed with an internal gear ring, and the internal gear ring is connected to a mounting chamber. A driving motor is mounted on the inner wall of the mounting chamber and is coaxially connected to the internal gear through a rocker. The driving rod 336 is eccentrically connected to the internal gear. First, when the internal gear is meshed with the internal gear ring at the upper end, the sleeve 1 334 and the sleeve 2 335 are both driven by the driving rod 33 Driven by the straight rod, 6 slides on the short rod at the upper end of the discontinuous rod 1 332 and the discontinuous rod 2 333, and gradually moves downward as the internal gear moves on the inner gear ring. At the same time, the driving rod 336 drives the sleeve 1 334 and the sleeve 2 335 to move. The sleeve 1 334 is transferred from the discontinuous rod 1 332 to the discontinuous rod 2 333. At the same time, the sleeve 2 335 is transferred from the discontinuous rod 2 333 to the discontinuous rod 1 332. When the sleeve 1 334 and the sleeve 2 335 move downward, they gradually push the short rod into the axle.

[0040] The intermittent rod 1 332 and the intermittent rod 2 333 are placed in a cross shape, and the intermittent rod 1 332 and the intermittent rod 2 333 are cut at the intersection to produce a fracture zone. The intermittent rod 1 332 and the intermittent rod 2 333 respectively form two short rods. The two short rods at the lower end are slidably installed on the slide 331. After the short rods are pushed, they are clamped on the axle. The distance between the two short rods formed after the intermittent rod 1 332 is interrupted is less than the length of the sleeve 1 334. Similarly, the distance between the two short rods formed after the intermittent rod 2 333 is interrupted is less than the length of the sleeve 2 335.

During specific use, the embedded rod 341 and the short rod first enter the structure of the axle itself synchronously, specifically enter the mounting part between the two suspensions, and after entering the frame, the controller controls the electromagnetic disk to cut off the power. At this time, the magnetic section on the bending rod 342 is disconnected from the embedded rod 341. At this time, the embedded rod 341 and the bending rod 342 form an L-shape, and after the bending rod 342 is unfolded, the cylinder in the auxiliary tube 343 retracts, pulling the bending rod 342 to move upward, thereby, the bending rod 342 is clamped on the mounting part of the axle.

[0044] like Figure 8 As shown, on the basis of embodiment 1, two front-to-back symmetrical blocking blocks 5 are installed at intervals on the upper end of the connecting track, and the blocking blocks 5 are installed on the connecting track for lifting.
