[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0041] Reference Figure 1-Figure 9 As shown, the present invention provides an auxiliary device for welding of mining machinery and equipment, comprising:

[0042] An operating table 1, the bottom of which is fixedly connected with four supporting legs 3 distributed in a rectangular shape, and the top of which is provided with a welding mechanism 4 for welding mining machinery and equipment;

[0043] Auxiliary fixing mechanism 2, the auxiliary fixing mechanism 2 includes a clamping assembly 21 and an adjusting assembly 22. The two sets of adjusting assemblies 22 are symmetrically arranged on the top of the operating table 1, and are used to adjust the position of the welded mining machinery and equipment parts. The clamping assembly 21 is arranged outside the adjusting assembly 22, and is used to fix the position of the mining machinery and equipment parts;

[0044] The adjustment assembly 22 includes a lifting seat 212, which is arranged on the top of the operating table 1. Two groups of symmetrically distributed push rods 217 are movably connected to the bottom of the lifting seat 212 through a pin shaft, and the bottom ends of the two groups of push rods 217 are movably connected to a moving bar 216 through a pin shaft. A placement plate 218 that can move left and right is arranged on the top of the lifting seat 212, and an electric telescopic rod 2111 for pushing the placement plate 218 to move is arranged on the outside of the lifting seat 212;

[0045] The clamping assembly 21 includes a U-shaped side plate 221, which is fixedly connected to the outer side of the placement plate 218. A movable plate 224 is arranged on the inner side of the U-shaped side plate 221. A threaded rod 223 is arranged on the movable plate 224. The bottom end of the threaded rod 223 is fixedly connected to a pressure block 226 for fixing the mining machinery and equipment.

[0046] In a further embodiment, referring to Figure 1-Figure 4 Two symmetrically distributed mounting grooves 213 are provided on the top of the operating table 1, and two lifting seats 212 are slidably connected to the inner sides of the corresponding mounting grooves 213. Two symmetrically distributed limit rods 215 are fixedly connected to the inner sides of the mounting grooves 213, and a moving bar 216 is slidably connected to the outer sides of the limit rods 215. A driving motor 211 is fixedly connected to the outer side of the operating table 1, and the driving motor 211 is fixedly connected to a bidirectional screw rod 214 through an output shaft. The front end of the bidirectional screw rod 214 passes through the rear side of the mounting groove 213 and is movably connected to the inner front side of the mounting groove 213 through a bearing. The two moving bars 216 are both threadedly connected to the outer sides of the bidirectional screw rod 214, and the front and rear ends of the outer sides of the bidirectional screw rod 214 are set as reverse threads.

[0047] Specifically, the limit rod 215 limits the moving track of the moving bar 216, ensuring that the two moving bars 216 can only move in the front-back direction, so that when the bidirectional screw rod 214 rotates, the two moving bars 216 can move in opposite directions.

[0048] In this embodiment, the driving motor 211 can drive the double-wire screw to rotate through the output shaft. Due to the setting of the reverse thread, the two moving bars 216 move in opposite directions, so that the height of the lifting seat 212 is adjusted by the push rod 217. By adjusting the height of the lifting seat 212, the auxiliary equipment can cooperate with the welding mechanism 4 to weld mining machinery and equipment parts of different heights, and has good practicality.

[0049] In a further embodiment, referring to Figure 4-Figure 6 A T-shaped slot 2113 extending to both sides is provided on the top of the lifting seat 212, a T-shaped block 2110 is fixedly connected to the bottom of the placement plate 218, the T-shaped block 2110 is slidably connected to the inner side of the T-shaped slot 2113, a fixed block 219 is fixedly connected to the outer side of the lifting seat 212, an electric telescopic rod 2111 is fixedly connected to the outer side of the fixed block 219, and a mounting block 2112 is fixedly connected to the telescopic end of the electric telescopic rod 2111, and the mounting block 2112 is fixedly connected to the bottom of the placement plate 218.

[0050] In this embodiment, the extension or shortening of the electric telescopic rod 2111 can be adjusted by the mounting block 2112 to adjust the position of the placement plate 218, so that the auxiliary equipment can weld parts of different sizes. If the parts are too small, the position of the placement plate 218 is moved to bring the parts to be welded closer to facilitate welding.

[0051] In a further embodiment, referring to Figure 6-Figure 9 The inner side of the U-shaped side plate 221 is movably connected with a transmission rod 2211 through a bearing, and the movable plate 224 is fixedly connected to the outer side of the transmission rod 2211. One end of the transmission rod 2211 penetrates the U-shaped side plate 221 and extends to the outer side of the U-shaped side plate 221. One end of the transmission rod 2211 is fixedly connected to a disk 225, and a spring 229 is fixedly connected to the outer side of the disk 225. The other end of the spring 229 is fixedly connected to a movable ring 227. The outer side of the movable ring 227 is fixedly connected to a plug rod 2213 arranged in a through shape. One end of the plug rod 2213 penetrates the disk 225 and is slidably connected to the disk 225. The end extending to the outside of the disk 225 is fixedly connected to a pull block 228. A fixing ring 2210 is fixedly connected to the outer side of the U-shaped side plate 221. Sockets 2212 distributed in an annular shape with equal intervals are provided on the outer side of the fixing ring 2210. The top of the threaded rod 223 is fixedly connected to a handle 222.

[0052] Specifically, when the insertion rod 2213 enters the inner side of the insertion hole 2212, the position of the transmission rod 2211 is limited under the action of the fixing ring 2210, so that it cannot rotate in the U-shaped side block, ensuring stability when clamping the parts and avoiding loose clamping.

[0053] In addition, when the insertion rod 2213 is moved out of the socket 2212, the pull block 228 is pulled outward, the movement of the pull block 228 drives the insertion rod 2213 to move, the movement of the insertion rod 2213 drives the movable ring 227 to move, and the movement of the movable ring 227 causes the insertion rod 2213 to move out of the socket 2212. At this time, the transmission rod 2211 can be rotated and the inclination angle of the movable plate 224 can be adjusted.

[0054] In this embodiment, rotating the handle 222 can drive the threaded rod 223 to rotate, thereby moving the pressure block 226 downward to fix and clamp the parts of the mining machinery and equipment on the placement plate 218 to prevent them from shifting during the welding process. If it is inconvenient to fix the parts from the upper pressure block 226, the limit on the transmission rod 2211 can be cancelled, and the inclination angle of the movable plate 224 can be adjusted, so that the clamping assembly 21 can clamp mining machinery and equipment parts of different shapes, further improving the practicality of the auxiliary equipment.

[0055] In a further embodiment, referring to Figure 1-Figure 3 The welding mechanism 4 includes a U-shaped seat 41 arranged on the top of the operating table 1, and a symmetrically distributed slide groove is opened inside the U-shaped seat 41. A movable electric slider 42 is arranged inside the slide groove, and two symmetrically distributed welding heads 43 are arranged on the opposite surfaces of the two electric sliders 42.

[0056] Specifically, a miniature electric push rod 217 is fixedly connected to the outer side of the electric slider 42, and the welding head 43 is arranged at the telescopic end of the electric push rod 217. Under the action of the electric push rod 217, the position of the welding head 43 can be adjusted so that it can weld parts of different heights.

[0057] In this embodiment, two symmetrically distributed electric sliders 42 arranged in the U-shaped seat 41 can slide in the front and rear directions, thereby driving the welding head 43 on the outside thereof to move. The two symmetrically arranged welding heads 43 can perform welding from the bottom and top of the parts simultaneously or in a single direction, respectively, greatly improving the welding efficiency.

[0058] The working principle of the present invention is as follows:

[0059] The mining machinery and equipment parts to be welded are placed on the placement seat, and the position of the mining machinery and equipment parts is adjusted according to the welding requirements. After adjusting to the appropriate position, the threaded rod 223 is rotated by the handle 222, and the rotation of the threaded rod 223 drives the pressing block 226 to move downward to fix the mining machinery and equipment parts on the placement plate 218;

[0060] At this time, the upper and lower welding heads 43 respectively weld the welding positions from the top and bottom of the mining machinery and equipment parts. After the welding is completed, the handle 222 is rotated in the opposite direction to remove the welded mining machinery and equipment parts.

[0061] When welding two mining machinery and equipment parts of different heights, the drive motor 211 is started, and the drive motor 211 drives the bidirectional screw rod 214 to rotate through the output shaft. The height of the mining machinery and equipment parts on the lower side is adjusted by the action of the moving bar 216 and the push rod 217, so that the mining machinery and equipment parts with the lower height reach the welding height, and welding is performed through the welding head 43.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
