Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle body pretreatment, in particular to a vehicle body pretreatment electrophoresis rotary immersion conveying device. BACKGROUND

[0002] The vehicle body pretreatment electrophoresis operation is an important technology for providing protective coating for the vehicle body. The vehicle body is delivered to the electrophoresis tank through the automatic turnover conveying device in the form of assembly line, and the delivered vehicle body is turned over in the solution in the electrophoresis tank. In combination with the action of the direct current power supply, the colloidal particles in the dispersion medium are accelerated to move towards the cathode or anode in a directional manner, thereby achieving the purpose of vehicle body electroplating.

[0003] In the current vehicle body electrophoresis operation, the vehicle body is mainly turned over in the head-to-tail direction. This turnover method requires a large space, and the turnover amplitude of the vehicle body head-to-tail is too large. At the moment when the vehicle body enters the electrophoresis tank, the solution in the electrophoresis tank will be greatly agitated under pressure. In addition, the internal structure of the vehicle body is complex, and at the moment when the solution enters the complex structure of the vehicle body, a bubble cavity will appear. In severe cases, the inner wall of the complex structure of the vehicle body cannot be fully immersed in the solution due to the bubble problem, thereby causing poor electrophoresis effect in the local part of the vehicle body. After electrophoresis, the vehicle body is greatly turned over and rises, and the accumulated solution will cause the range of splashing to increase after falling due to the sharp increase in the height of the vehicle body, which will cause a certain loss of the electrophoresis solution.

[0004] In view of this, a vehicle body pretreatment electrophoresis rotary immersion conveying device is designed to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0048] ​In order to make the objects, technical solutions and advantages of the present application clearer, further detailed description will be made to the present application with reference to the specific embodiments and the accompanying drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0049] It is to be understood that the above description is only exemplary and is not intended to limit the scope of the present application.

[0050] Some embodiments of the present application provide a vehicle body pretreatment electrophoresis rotary immersion conveying device.

[0051] Embodiment 1:

[0052] In combination with Figures 1 to 11 As shown in the drawings, the vehicle body pretreatment electrophoresis rotary immersion conveying device provided by the present application comprises a vehicle frame 100, four sets of vehicle body calibration mechanisms 500 arranged outside the vehicle frame 100, two sets of ring carrier mechanisms 400 arranged outside two of the vehicle body calibration mechanisms 500, and the number of the ring carrier mechanisms 400 is two, a width-adapting assisting mechanism 600 arranged in the two sets of ring carrier mechanisms 400, the width-adapting assisting mechanism 600 being used for assisting the four sets of vehicle body calibration mechanisms 500, a vehicle body positioning mechanism 300 arranged on the two sets of ring carrier mechanisms 400, and a beam rail 200 arranged in the vehicle body positioning mechanism 300, the beam rail 200 being used for providing a lifting platform for conveying the vehicle body positioning mechanism 300, the vehicle body positioning mechanism 300 being used for providing a freely stretched platform for the two sets of ring carrier mechanisms 400, the two sets of ring carrier mechanisms 400 being used for adapting the two ends of the vehicle frame 100, the four sets of vehicle body calibration mechanisms 500 being used for quickly clamping four shaft holes at the two ends of the vehicle frame 100, and the width-adapting assisting mechanism 600 being used for controlling the four sets of vehicle body calibration mechanisms 500 to rotate along the inner sides of the two sets of ring carrier mechanisms 400, and driving the suspended rear vehicle frame 100 to rotate in the electrophoresis tank with the smallest amplitude.

[0053] The ring carrier mechanism 400 comprises an inner tooth ring 440, an outer tooth ring 450, two first ring rails 410, and two second ring rails 420, and the second ring rail 420 is provided with a ring tooth 430 away from the side of the first ring rail 410;

[0054] The number of the inner tooth ring 440 and the outer tooth ring 450 is two, and the recess on the inner side of the inner tooth ring 440 and the recess on the outer side of the outer tooth ring 450 are both provided with an arc-shaped rack;

[0055] The outer wall of the first ring rail 410 is provided with two first supporting feet, the outer wall of the second ring rail 420 is provided with two second supporting feet, and the first supporting feet and the second supporting feet are fixed by combined bolts;

[0056] The vehicle body calibration mechanism 500 comprises a second sliding block 520 and a first sliding block 510 arranged in the sliding channel inside the first ring rail 410 and the second ring rail 420, a fifth traction frame 560 movably arranged at the outer end of the second sliding block 520, a sixth traction frame 570 movably arranged at the other end of the fifth traction frame 560, a third traction frame 540 movably arranged at the outer end of the first sliding block 510, a fourth traction frame 550 movably arranged at the other end of the third traction frame 540, a chuck 580 movably arranged between the sixth traction frame 570 and the fourth traction frame 550, and a shaft sleeve positioning piece 590 arranged inside the chuck 580, and a nut 5901 is arranged on the threaded section of the shaft sleeve positioning piece 590.

[0057] The middle part of each of the two second sliding blocks 520 is provided with a pin rod, and the bottom end of the built-in tooth ring 440 is movably arranged at the middle part of one of the pin rods, and the bottom end of the outer tooth ring 450 is movably arranged at the outer end of the other pin rod.

[0058] The built-in tooth ring 440 and the outer tooth ring 450 are stacked along the head-to-tail direction of the vehicle frame 100, and are used to control the synchronous extension and contraction of the two sets of vehicle body calibration mechanisms 500.

[0059] The number of shaft sleeve positioning pieces 590 is four, and the four shaft sleeve positioning pieces 590 are used to adaptively connect the four shaft holes at the head end and the tail end of the vehicle frame 100.

[0060] The third traction frame 540 and the fifth traction frame 560 are the same in structure, and each comprises two circular-arc-shaped gaskets and two end rods.

[0061] The end of the shaft sleeve positioning piece 590 towards the shaft hole of the vehicle frame 100 is provided with a T-shaped insertion rod, and the T-shaped insertion rod is used to adaptively connect the shaft holes in different models of vehicle frames 100.

[0062] By using the vehicle body calibration mechanism 300 to fix the two sets of ring carrier mechanisms 400, the two sets of ring carrier mechanisms 400 provide a ring-shaped support carrier for the fixation of the vehicle frame 100. When the vehicle frame 100 is inserted and connected by the four shaft sleeve positioning pieces 590 and is suspended in the middle of the inner cavities of the two sets of ring carrier mechanisms 400, the vehicle frame 100 as a whole can be fixed in a way with the smallest contact area. After the two sets of ring carrier mechanisms 400 are moved to directly above the electrophoresis tank, the fixed vehicle frame 100 can enter the inner cavity of the electrophoresis tank with the smallest amplitude together with the two sets of ring carrier mechanisms 400. After the vehicle frame 100 is completely immersed in the electrophoresis solution, the circular rotation of the four sets of vehicle body calibration mechanisms 500 is driven by the appropriate width of the auxiliary rotation mechanism 600. At this time, the vehicle frame 100 can rotate at a constant speed in the electrophoresis solution. This process can avoid the vehicle frame 100 from being flipped with too large an amplitude, causing the electrophoresis solution to overflow under pressure, and can also improve the coverage of the electrophoresis solution on the complex structure of the vehicle frame 100.

[0063] Example 2:

[0064] Combination Figure 3 , Figure 8 as well as Figure 9 As shown, based on Embodiment 1, there are four first ring rails 410 and four second ring rails 420, and two adjacent first ring rails 410 and two adjacent second ring rails 420 form a circular track.

[0066] The bottom of the outer end of the stabilizing cover plate 330 has four grooves, which are used to limit and constrain the top ends of the two adjacent first ring rails 410 and the two adjacent second ring rails 420.

[0067] The body mounting mechanism 300 controls the lateral extension of two sets of ring-mounted mechanisms 400 to adapt to the front and rear ends of the frame 100.

[0068] Preferably, the slide 310 is composed of a slide table, an elliptical pad, and two U-shaped outer frames, and two stabilizing cover plates 330 are movably mounted on the two U-shaped outer frames, while the hydraulic component 320 is fixedly mounted in the middle of the elliptical pad.

[0069] When the slide table is pulled laterally along the beam rail 200 by the external drive device, the regular lifting and lowering of the beam rail 200 will eventually drive the two sets of ring-load mechanisms 400 and the fixed frame 100 to move into the electric pool. As the hydraulic component 320 operates, its internal hydraulic rod will push the end plate 350 to rise and fall. Finally, the two first traction frames 340 and the stabilizing cover plate 330 will drive the two sets of ring-load mechanisms 400 to quickly adapt to the frame 100 of different lengths.

[0076] When the position control motor 670 is started, the transmission shaft in the position control motor 670 rotates in cooperation with the extension shaft 680, at this time, the fixed gear 690 arranged at the other end of the transmission shaft in the position control motor 670 and the sliding gear 660 at the other end of the extension shaft 680 are driven at the same speed, at this time, the two groups of ring loading mechanisms 400 can be freely stretched and then can be provided with stable kinetic energy by the fixed gear 690 and the sliding gear 660, so as to ensure the constant stretching angle of the two built-in tooth rings 440 and the two external tooth rings 450.

[0077] The other end of the cross beam 610 is fixedly provided with a machine cover 6101, the machine cover 6101 is internally provided with a rotating circular motor 6102, and a tooth disc 6103 is arranged on the transmission shaft in the rotating circular motor 6102;

[0078] The tooth disc 6103 rotates along the two closed ring teeth 430, so as to drive the whole width-adaptive assisting mechanism 600 and the four groups of vehicle body alignment mechanisms 500 to rotate.

[0079] Preferably, the end of the inner side of the cover 6101 is fixed on the crossbeam 610 by two rivets, when the rotating motor 6102 operates, the internal transmission shaft will cooperate with the gear disc 6103 to rotate at a constant speed, and finally the gear disc 6103 will rotate at a constant speed along the two arc teeth 430 on the outer side of the adjacent one set of inner tooth ring 440 and outer tooth ring 450, so as to ensure that the frame 100 fixed by the four sets of body alignment mechanism 500 can rotate in the electrophoretic solution with the smallest amplitude.

[0083] As the bottom ends of the inner tooth ring 440 and the outer tooth ring 450 approach each other, the two second sliding blocks 520 arranged at the bottom of the inner tooth ring 440 and the outer tooth ring 450 will continuously approach, and the two shaft sleeve positioning members 590 symmetrically distributed horizontally will be pressed and stretched outward, then the frame 100 is delivered into the gap in the middle of the two sets of ring carrier mechanisms 400 by using the conveying device, the hydraulic member 320 is operated according to the length of the frame 100, at this time, the internal hydraulic sub-rod will push the end plate 350 to rise and fall, and the two first traction frames 340 movably installed on the end plate 350 will push the two stability cover plates 330 to relatively stretch along the sliding seat 310, finally, the two sets of ring carrier mechanisms 400 can adapt to the head end and tail end of the frame 100, until the two sets of shaft sleeve positioning members 590 in the two sets of ring carrier mechanisms 400 are adapted and symmetrical with the shaft holes of the head end and tail end of the frame 100;
