Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically to positioning tooling for the production of thermal insulation covers. Background Technology

[0002] In tire production, a heat insulation cover is required. This cover consists of inner and outer rings and an insulation layer sandwiched between them. Both the inner and outer rings are made of steel plates. During production, the inner ring is first assembled using curved steel plates, then the insulation layer is attached to the outer wall of the inner ring. Next, curved steel plates are used to assemble the outer ring on the outer wall of the insulation layer. Finally, the inner and outer rings are welded together. To address this issue, we propose a positioning fixture to solve the problem of positioning and assembling the curved steel plates during the production of the heat insulation cover.

It also includes: support columns 3 installed at the four corners of the top outer wall of the base plate 1. The top of the four support columns 3 is fixed with the same positioning platform 4. A pushing component 5 is installed in the middle of the top outer wall of the base plate 1. The top outer wall of the positioning platform 4 has multiple equally spaced sliding openings 6. The inner wall of the sliding openings 6 is slidably connected with positioning components 7. A smoke exhaust component 8 is installed on the top of the positioning platform 4.

[0020] It should be noted that the curved steel plate can be placed on the positioning component 7 for fixation, which facilitates the connection of the curved steel plate into a circle. Before use, the device can be adjusted according to the size of the insulation cover to be produced. By pushing component 5, multiple positioning components 7 can be moved simultaneously, and the diameter of the circle formed by the lines connecting the positioning components 7 can be adjusted. This makes it suitable for the production of insulation covers of different sizes. The smoke exhaust component 8 can absorb and exhaust the welding fumes during the welding process in the production of the insulation cover, preventing the fumes from affecting the vision of the welding personnel.

[0021] In a preferred embodiment, the actuating component 5 includes an electric push rod 501 and a plurality of equidistant connecting rods 502 that are rotatably mounted on the outer wall of the piston rod of the electric push rod 501.

[0022] It should be noted that the piston rod of the electric push rod 501 can be moved by the traction positioning assembly 7 of the connecting rod 502.
