[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figures 1 to 5 As shown, the present invention provides a truncated table welding auxiliary device, including a rotary positioning mechanism 2 and a rotary tightening mechanism 4.

[0026] The rotation positioning mechanism 2 is installed on the base 1, and includes two symmetrically arranged rotating seats 201 that can be driven by the power mechanism to rotate synchronously in opposite directions.

[0027] The power mechanism includes an arc-shaped guide seat 209 that provides guidance for the rotation of the rotating seat 201, and a gear 208 is rotatably installed on the arc-shaped guide seat 209. The rotating seat 201 is connected to the upper end of the gear 208. A guide slide 205 is provided on the base 1, and a bidirectional lead screw 204 whose end is driven to rotate by a turntable 210 is rotatably installed parallel to the guide slide 205. Two sleeves 206 are symmetrically mounted on the screws of different rotation directions of the bidirectional lead screw 204 through screw nuts (not shown in the figure), and the sleeve 206 is slidably guided by the guide slide 205. A rack 207 that can mesh with the bottom of the gear 208 on the corresponding side is installed on the sleeve 206.

[0028] Two guide rollers 202 are arranged on the rotating seat 201 to rotate in parallel, and the outer wall of the hollow truncated cone column 10 can be tangent to the two guide rollers 202 on the corresponding side. In addition, a plurality of balls 203 are evenly distributed on the guide rollers 202 .

[0029] The rotating and tightening mechanism 4 includes mounting seats 401 which are arranged on both sides of the rotating and positioning mechanism 2 and can be lifted and lowered.

[0030] The mounting seat 401 is driven to rise and fall by the lifting mechanism 3, and the lifting mechanism 3 includes two vertical guide rails 301 installed on the base 1. The mounting seat 401 is vertically slidably installed in the vertical guide rails 301, and a threaded rod 302 is rotatably installed parallel to the vertical guide rails 301. The mounting seat 401 is fitted on the threaded rod 302 through a nut sleeve, and the threaded rod 302 is driven to rotate by a handle 303. Pulleys 304 are both mounted on the two threaded rods 302, and the two pulleys 304 are connected by a belt 305. The turntable 402 is installed on the inner side of the mounting seat 401 on the corresponding side.

[0031] A turntable 402 is rotatably mounted inside the mounting seat 401. The turntable 402 can be driven to rotate by a rotary motor (not shown in the figure). A driving cylinder 404 is horizontally arranged inside the turntable 402. A side pressure plate 405 that can act on the outside of the positioned hollow cylindrical column 10 is arranged inside the driving cylinder 404. An anti-slip pad (not shown in the figure) is arranged inside the side pressure plate 405. The two driving cylinders 404 drive the two side pressure plates 405 to move in opposite directions at equal distances and synchronously.

[0032] The working principle of the device of the present invention is:

[0033] First, when the rotating seat 201 is adjusted to be horizontal, the hollow cone column 10 is placed between two guide rollers 202 on the corresponding side with the side pressure surface 30 facing outward.

[0034] Afterwards, the rotating turntable 210 drives the bidirectional screw 204 to rotate, and the sleeves 206 mounted on the screws of different rotation directions of the bidirectional screw 204 will move away from each other under the guidance of the guide slide 205, and the rack 207 on the sleeve 206 will drive the gear 208 on the corresponding side to rotate, and the gear 208 drives the rotating seat 201 to rotate along the arc-shaped guide seat 209, and the two rotating seats 201 rotate at the same time. The two hollow circular columns 10 to be welded rotate at the same angle and move toward each other under the guidance of the ball 203 on the guide roller 202. On the one hand, after the hollow circular column 10 rotates, the welding surface 20 of the inner hollow circular column 10 gradually tends to be vertical; on the other hand, due to the positioning and guiding of the guide roller 202, the axes of the two hollow circular columns 10 can be located in the same vertical plane. And the welding surfaces 20 of the two hollow circular columns 10 are directly opposite.

[0035] Next, the turning handle 303 is rotated to drive the threaded rod 302 to rotate, and the mounting seats 401 on the two threaded rods 302 connected by the belt 305 are synchronously lifted and lowered vertically, so that the side pressure plate 405 moves to a position facing the side pressure surface 30 of the hollow round column 10. The side pressure plates 405 on both sides are driven by the driving cylinder 404 to synchronously squeeze the side pressure surfaces 30 of the two hollow round columns 10 after positioning, thereby completing the positioning of the welding part of the hollow round column 10.

[0036] Finally, the rotating motor drives the turntable 402 to rotate, so that the hollow round column 10 clamped in the middle by the two side pressure plates 405 rotates, and the guide rollers 202 provide guidance for the rotation of the hollow round column 10. The welding tool is aligned with the weld between the hollow round columns 10, and the circumference of the weld of the rotating hollow round column 10 can be welded quickly.

[0037] The present invention can quickly complete the loading and positioning of the hollow circular column 10 through the cooperation between the rotating positioning mechanism 2, the lifting mechanism 3 and the rotating clamping mechanism 4. The device can be suitable for positioning and clamping hollow circular columns 10 of various specifications; and the device can realize the circumferential rotation of the weld, which can improve the efficiency and accuracy of welding.

[0038] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
