BRIEF DESCRIPTION OF DRAWINGS

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] Fig. 1 This is a schematic diagram of the structure of this utility model.

[0011] Fig. 2 This is a structural diagram of the clamp.

[0012] Fig. 3 This is a schematic diagram of the installation structure of the bracket and idler roller. Detailed Implementation

[0013] The present invention will now be described in detail with reference to specific embodiments:

[0014] like Figs. 1 to 3 The double-layer DC track roller partition welding indexing mechanism shown includes a base 1, a clamp 2, a positioning rod 3, a support plate 4, a cylinder 5, a bracket 11, and rollers 12. The base 1 has symmetrical notches 13 on its left and right sides. The bracket 11 is fixedly installed in the notches 13. The two rollers 12 are rotatably installed on the bracket 11. The cylinder body of the cylinder 5 is fixedly installed in the base 1. The support plate 4 is fixedly installed on the piston rod of the cylinder 5. The inner surface of the clamp 2 has a ring array of slots 22 that cooperate with the partition 8. The top of the clamp 2 is provided with a threaded hole. The positioning rod 3 is screwed into the threaded hole at the top of the clamp 2.

[0015] The clamp 2 consists of an outer clamp body 20 and an inner core body 21. The inner core body 21 is screwed and fixedly installed on the outer clamp body 20. The outer clamp body 20 has clamp ears 24 fixedly provided on both sides. The clamp ears 24 are locked and fixed by bolts. The inner core body 21 can be replaced and used with inner rollers 7 of different diameters.

[0016] A guide rod 6 is fixedly installed at the bottom of the pallet 4, and a guide sleeve 31 is fixedly installed on the base 1. The lower end of the guide rod 6 is slidably installed in the guide sleeve 31. Through the guiding effect of the guide rod 6 and the guide sleeve 31, the straightness of the pallet 4 when moving up and down can be improved.

[0017] A rubber pad is fixedly installed on the top surface of the pallet 4 to prevent rigid collision between the pallet 4 and the inner roller 7 or the partition 9, thereby reducing noise.

[0018] The inner roller 7 is symmetrically provided with flow channel holes 71 in annular array at both ends. First, the partition plate 9 of each flow channel is fixedly embedded in the bayonet 22 of the hoop 2, and then the hoop 2 is fixedly installed at both ends of the inner roller 7 after pre-positioning by the positioning rod 3 and one of the flow channel holes 71. At this time, the partition plate 9 is in close contact with the inner roller 7, and the end shaft 72 at both ends of the inner roller 7 is placed on the two supporting rollers 12 to facilitate rotation of the inner roller 7 and the end shaft 72. The operator welds and fixes the partition plate 9 and the inner roller 7. In order to avoid rotation of the inner roller 7 and the end shaft 72 during welding operation, the piston rod of the air cylinder 5 is extended to push the supporting plate 4 to move upward, and the combination of the partition plate 9, the inner roller 7, the hoop 2 and the end shaft 72 is lifted upward to improve the stability during welding operation. When the inner roller 7 needs to be rotated, the piston rod of the air cylinder 5 is retracted to drive the supporting plate 4 to move downward to reset, so that the end shaft 72 of the inner roller 7 falls on the two supporting rollers 12 for convenience, so as to facilitate rotation and adjustment of the angle of the partition plate 9, the inner roller 7, the hoop 2 and the end shaft 72, and facilitate welding operation on other partition plates 9.
