Description

Technical Field

[0001] This utility model relates to the field of welding technology for tunneling and anchoring machine parts, specifically a welding assembly tooling for the intermediate frame of a tunneling and anchoring machine. Background Technology

[0002] A roadheader is a mechanical device that uses the axial pressure and rotational force of the cutting tool to crush the rock surface and directly break the ore to form a tunnel or shaft. The intermediate frame of the roadheader connects the various key components of the roadheader into a whole, ensuring that the components can work in coordination. During the production of the intermediate frame, the tooling needs to be positioned and welded by the welding group.

[0003] In traditional welding, when using the tooling, the worker places the intermediate frame on the tooling to position it and align the two intermediate frame components. After that, the welding equipment is used to weld them together. However, during the welding process of the intermediate frame, the intermediate frame components have a certain weight and there is no support for them. As a result, the intermediate frame is prone to swaying under its own weight or the welding operation force, which can lead to misalignment of the welding joints of the intermediate frame components. This reduces the stability of the intermediate frame of the tunneling and anchoring machine during the welding process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding assembly fixture for the intermediate frame of a roadheader, which solves the problem that the intermediate frame is prone to swaying under its own weight or welding operation force due to the weight of the intermediate frame components and the lack of any support for the intermediate frame components, thereby reducing the stability of the intermediate frame of the roadheader during the welding process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding assembly fixture for the intermediate frame of a tunneling and anchoring machine, comprising a base, a bracket fixedly connected to the surface of the base by bolts, a placement recess fixedly connected to the upper outer wall of the bracket by bolts, a pressure plate fixedly connected to the upper outer wall of the bracket near the placement recess by bolts, an empty box provided above the base, a stud threadedly connected to the inner wall of the empty box, a vertical block rotatably connected to the end of the stud by a bearing, a vertical plate fixedly connected to the side wall of the vertical block, a round rod slidably connected to the surface of the vertical plate, a column fixedly connected to the back of the round rod, the column penetrating the empty box and movably connected to the empty box, and a top plate fixedly connected to the top of the column.

[0006] Preferably, the bottom of the inner wall of the empty box is provided with a sliding groove, and the bottom of the upright plate is slidably engaged with the inner wall of the sliding groove.

[0007] Preferably, a second connecting lug is fixedly connected to the lower side wall of the empty box, the second connecting lug is fixedly connected to the surface of the base by bolts, the surface of the base is provided with a slide rail, the bottom of the empty box is fixedly connected to a connecting seat, the bottom of the connecting seat is fixedly connected to a pulley, and the outer wall of the pulley is in contact with the inner wall of the slide rail.

[0008] Preferably, a groove is provided on the upper part of the inner wall of the bracket, and a protrusion is fixedly connected to the bottom of the recessed block, with the outer wall of the protrusion inserted into the inner wall of the groove.

[0009] Preferably, a first connecting ear is fixedly connected to the side wall of the base, and the surface of the first connecting ear is provided with a mounting hole. Beneficial effects

[0010] This utility model provides a welding assembly fixture for the intermediate frame of a roadheader. It has the following advantages: This welding assembly fixture for the intermediate frame of a roadheader, through the cooperation of studs, upright blocks, upright plates, round rods, columns, and top plates, supports the intermediate frame components during welding. This solves the problem that, due to the weight of the intermediate frame components and the lack of any support, the intermediate frame is prone to swaying under its own weight or welding operation forces, thus reducing the stability of the roadheader's intermediate frame during welding.

[0011] The position of the top plate can be adjusted by the cooperation between the second connecting ear, the connecting seat, the pulley and the slide rail. This solves the problem that when welding intermediate frame components, the position of the top plate is fixed and cannot be adjusted because the intermediate frame components are of different sizes, which makes it impossible to support intermediate frame components of different sizes.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Because the intermediate frame components have a certain weight and there is no support for them, the intermediate frame is prone to swaying under its own weight or welding operation force, which reduces the stability of the intermediate frame of the tunneling and anchoring machine during the welding process.

[0016] In view of this, the present invention provides a welding assembly tooling for the intermediate frame of a roadheader. Through the cooperation between studs, upright blocks, upright plates, round rods, columns and top plates, the intermediate frame components are supported during welding. This solves the problem that the intermediate frame components have a certain weight and there is no support for them, which makes the intermediate frame prone to shaking under its own weight or welding operation force, thus reducing the stability of the intermediate frame of the roadheader during the welding process.

[0017] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0018] Example 1, by Figure 1-4 It is understood that a welding assembly tooling for the intermediate frame of a tunneling and anchoring machine in this case includes a base 1, a bracket 2 fixedly connected to the surface of the base 1 by bolts, a placement recess 3 fixedly connected to the upper part of the outer wall of the bracket 2 by bolts, a pressure plate 4 fixedly connected to the side of the upper part of the outer wall of the bracket 2 near the placement recess 3 by bolts, an empty box 9 is provided above the base 1, a stud 10 is threadedly connected to the inner wall of the empty box 9, a vertical block 11 is rotatably connected to the end of the stud 10 by a bearing, a vertical plate 12 is fixedly connected to the side wall of the vertical block 11, a round rod 13 is slidably connected to the surface of the vertical plate 12, a column 14 is fixedly connected to the back of the round rod 13, the column 14 penetrates the empty box 9 and is movably connected to the empty box 9, and a top plate 15 is fixedly connected to the top of the column 14. In the specific implementation process, it is worth noting that the base 1 is provided with several threaded holes for material discharge at equal intervals. The worker rotates the bolts on the bracket 2 to release the bracket 2 from its fixation. The worker moves the bracket 2, which can move left, right, forward, and backward. After the bracket 2 has moved, the worker rotates the bolts on the bracket 2 again to rotate the bolts into the corresponding threaded holes, thereby changing the position of the bracket 2. The worker rotates the bolts on the placement recess 3 to change the shape or size of the placement groove on the surface of the placement recess 3, thereby adapting to the assembly and welding of intermediate frame components of different sizes and shapes. When assembling and welding the intermediate frame components of the excavator and anchor machine, the worker places the intermediate frame components into the placement recesses 3 on both sides in sequence to position the intermediate frame. After aligning the welding positions of the intermediate frame, the worker moves the pressure plate 4 and inserts the pressure plate 4 into the top of the bracket 2 so that the pressure plate 4 contacts the upper surface of the intermediate frame. After completion, the worker rotates the bolts on the pressure plate 4 to fix the pressure plate 4 to the bracket 2, thereby fixing the intermediate frame components. After fixing, the workers rotate the studs 10 on the empty box 9 in sequence. The studs 10 drive the blocks 11 to move, the blocks 11 drive the plates 12 to move, and the plates 12 drive the round rods 13 to slide in the limiting grooves on their surfaces. The round rods 13 drive the columns 14 to move, and the columns 14 move in the empty box 9. The columns 14 are then limited, and the columns 14 drive the top plate 15 to move, so that the top plate 15 contacts the lower surface of the intermediate frame component. After this is completed, the workers stop rotating the studs 10. When the intermediate frame component is welded, the workers rotate the studs 10 in the opposite direction, so that the top plate 15 descends back to its initial position and no longer contacts the lower surface of the intermediate frame component. The workers then rotate the bolts on the pressure plate 4 in the opposite direction to remove the pressure plate 4, release the fixing of the intermediate frame component, and remove it. This provides support for the intermediate frame component during welding. Furthermore, a groove 16 is provided at the bottom of the inner wall of the empty box 9, and the bottom of the upright plate 12 is slidably engaged with the inner wall of the groove 16. In the specific implementation process, it is worth noting that when the upright plate 12 moves, the upright plate 12 slides in the slide groove 16, thereby guiding the upright plate 12 and achieving stability and movement accuracy of the explosive upright plate 12 during the movement process. Furthermore, a second connecting ear 17 is fixedly connected to the lower side wall of the empty box 9. The second connecting ear 17 is fixed to the surface of the base 1 by bolts. A slide 20 is provided on the surface of the base 1. A connecting seat 18 is fixedly connected to the bottom of the empty box 9. A pulley 19 is fixedly connected to the bottom of the connecting seat 18. The outer wall of the pulley 19 is attached to the inner wall of the slide 20. In the specific implementation process, it is worth noting that when welding intermediate frame components of different sizes, the worker rotates the bolt on the second connecting lug 17 to release the empty box 9 from its fixation. Then, the worker moves the empty box 9, which in turn moves the connecting seat 18. The connecting seat 18 then moves the pulley 19, which moves in the slide rail 20. The empty box 9 then moves the top plate 15. After the top plate 15 is moved to the designated position, the worker rotates the bolt on the second connecting lug 17 again to rotate the bolt into the corresponding threaded hole, thus re-fixing the position of the empty box 9 and adjusting the position of the top plate 15.

[0019] Example 2, by Figure 1 , 2 As can be seen from 4, a groove 8 is provided on the upper part of the inner wall of the bracket 2, and a protrusion 7 is fixedly connected to the bottom of the recess 3. The outer wall of the protrusion 7 is inserted into the inner wall of the groove 8. In the specific implementation process, it is worth noting that when replacing the placement recess 3, the staff aligns the protrusion 7 on the bottom of the replacement placement recess 3 with the groove 8, thereby inserting the protrusion 7 into the groove 8 to achieve positioning between the placement recess 3 and the bracket 2, so as to quickly replace the replacement placement recess 3, while restricting the horizontal displacement of the placement recess 3. Furthermore, a first connecting ear 5 is fixedly connected to the side wall of the base 1, and a mounting hole 6 is provided on the surface of the first connecting ear 5; In the specific implementation process, it is worth noting that the mounting hole 6 can be a threaded hole. The workers will install the entire tooling onto the external welding equipment through the mounting hole 6 on the first connecting lug 5. The number and position of the first connecting lug 5 are designed according to the overall weight and stress distribution of the tooling. The dimensional accuracy of the mounting hole 6 must be compatible with the external connecting bolts to ensure the stability of the tooling after installation and prevent the tooling from shifting as a whole during the welding process.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
