Description

Technical Field

[0001] The utility model relates to the technical field of fly plates of motor frames, in particular to a positioning fixture for welding fly plates of a roadheader motor frame. Background Technique

[0002] The roadheader motor is the core power component of the roadheader. The roadheader motor provides power for each working mechanism of the roadheader, drives the cutting head to rotate and cut rocks and coal blocks, pushes the roadheader to move forward, drives the conveyor to operate, etc. It is the key to ensuring the normal operation of the roadheader and realizing efficient tunneling. It has a simple structure, reliable operation, and low maintenance cost, and is widely used in medium and low voltage power supply systems. It can be divided into asynchronous motors and synchronous motors. Asynchronous motors have good speed regulation performance and can adapt to different working loads; synchronous motors have higher power factors and efficiencies.

[0003] The fly plate of the roadheader motor frame is an important component on the roadheader motor frame. The fly plate is usually used to connect the motor frame and other components, such as the fuselage of the roadheader or other support structures. It provides a firm connection point to ensure that the motor maintains a stable position during operation.

[0004] In daily work, it is found that when the existing welded fly plate of the roadheader motor frame is welded to the roadheader motor frame, marking lines will be made, and finally the welding is carried out with the marking lines as the reference to draw the position lines of the fly plate. The welding spot-welds the fly plate according to the marked position, resulting in inaccurate positioning of the fly plate. After welding, it is easy to have deviations in the welding of the fly plate, causing the motor to need to be repaired, resulting in inconvenient operation and affecting the welding efficiency. Furthermore, it leads to the problem that the existing welded fly plate of the roadheader motor frame is not easy to position during welding and is prone to deviations and requires repair. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages of being not easy to position and prone to deviations and requiring repair in the existing technology, and to propose a positioning fixture for welding fly plates of a roadheader motor frame.

[0006] To achieve the above object, the utility model adopts the following technical solutions: a positioning tire for welding a fly plate of an excavator motor base, including a main body of the excavator motor base and an auxiliary device. Positioning plates are respectively arranged on both sides of the main body of the excavator motor base. A positioning bushing is installed on the inner wall of the positioning plate. Two tension bars are welded between the two positioning plates. A blocking block is arranged between the two positioning plates. Fly plate bodies are arranged on both sides of the main body of the excavator motor base. Through holes are formed on the surface of the fly plate body.

Then, after connecting the positioning bushing with the main body of the excavator motor base, the fly plate body can be inserted into the hollow sleeve. Then, the two plug blocks can be pushed. The plug blocks can be respectively inserted into the through holes and the through holes on the surface of the fly plate body. Then, the fly plate body is pressed by using the pressing component, and then spot welding operation can be carried out.

Flying plate bodies 5 are arranged on both sides of the main body 1 of the roadheader motor seat. Through holes are formed on the surface of the flying plate body 5. The auxiliary device 6 is arranged on the surface of the positioning plate 2.

[0022] Specifically, the auxiliary device 6 includes fixing plates 61. The number of the fixing plates 61 is two. The two fixing plates 61 are respectively fixedly connected to the surface of the positioning plate 2 close to the flying plate body 5. A hollow sleeve 62 is fixedly connected to the surface of the fixing plate 61. The flying plate body 5 is inserted into the hollow sleeve 62. Two sliding grooves are formed on the surface of the fixing plate 61. Plug blocks 63 are slidably connected to the inner walls of the sliding grooves. Two through holes 66 are formed on the inner wall of the hollow sleeve 62. The plug blocks 63 are respectively inserted into the inner walls of the through holes 66 and the through holes on the surface of the flying plate body 5. A pressing component 65 is arranged on the inner wall of the hollow sleeve 62.

[0023] In this embodiment: when welding the flying plate body 5, the main body 1 of the roadheader motor seat can be placed between the positioning plates 2. Subsequently, after connecting the positioning bushing 7 with the main body 1 of the roadheader motor seat, the flying plate body 5 is inserted into the hollow sleeve 62. Then, the two plug blocks 63 can be pushed. The plug blocks 63 can be respectively inserted into the through holes 66 and the through holes on the surface of the flying plate body 5. Subsequently, the flying plate body 5 is pressed by using the pressing component 65, and then the spot welding operation can be carried out.

[0024] Specifically, a pull rod 64 is fixedly connected to one side surface of the two plug blocks 63. The pull rod 64 is arranged in a U shape. The two plug blocks 63 can be driven to move through the pull rod 64, improving the overall usability.

[0025] Specifically, the pressing component 65 includes a slider 651. The slider 651 is slidably connected to the inner wall of the hollow sleeve 62. A fixed shaft 653 is fixedly connected to the upper surface of the slider 651. A pressing block 652 is rotatably connected to the surface of the fixed shaft 653. A screw rod 655 is rotatably connected to the inner wall of the hollow sleeve 62. The screw rod 655 is threadedly connected to the inner wall of the slider 651.

[0026] In this embodiment: when pressing is required, the screw rod 655 can be rotated. The screw rod 655 controls the movement of the slider 651 and the pressing block 652, so that the pressing block 652 can press on the flying plate body 5 for pressing. The pressing block 652 is rotated on the fixed shaft 653, so as to facilitate the insertion of the flying plate body 5 into the hollow sleeve 62.

[0027] Specifically, a gasket 654 is fixedly connected to the surface of the pressing block 652 on the side close to the flying plate body 5. When the pressing block 652 presses against the flying plate body 5, the gasket 654 can play a protective role.

[0028] Specifically, the insertion block 63 is composed of a limiting block adapted to the through hole 66 and the through hole on the surface of the flying plate body 5, and a rectangular block that slides on the inner wall of the chute on the surface of the fixing plate 61.

[0029] Specifically, a magnetic strip 67 is fixedly connected to the inner wall of the insertion block 63. The hollow sleeve 62 is made of iron material, and the magnetic strip 67 is magnetically connected to the iron material-made hollow sleeve 62.

[0030] In this embodiment: After the insertion block 63 is completely inserted into the hollow sleeve 62, the magnetic strip 67 will attract the iron material-made hollow sleeve 62 to achieve the positioning function.

[0031] Working principle: During welding, first place the main body 1 of the roadheader motor base between the positioning plates 2. Then align the shaft hole in the main body 1 of the roadheader motor base with the positioning plate 2, and insert the positioning bushing 7 into the shaft hole in the main body 1 of the roadheader motor base for positioning. Subsequently, when welding the flying plate body 5, insert the flying plate body 5 into the hollow sleeve 62. The welding end of the flying plate body 5 contacts the main body 1 of the roadheader motor base. Then drive the two insertion blocks 63 to be inserted into the through holes 66 on the surface of the hollow sleeve 62 and the through holes on the surface of the flying plate body 5 through the pull rod 64. After insertion, the magnetic strip 67 can attract the iron material-made hollow sleeve 62. Then, the pressing plate can be rotated in the fixed shaft 653. After the pressing plate and the gasket 654 rotate to one side of the flying plate body 5, rotate the screw 655. The screw 655 can drive the slider 651 to move on the side close to the flying plate body 5 in the hollow sleeve 62. After moving to a certain position, the pressing plate can cooperate with the gasket 654 to press on the flying plate body 5, thereby achieving precise positioning and restriction of the flying plate body 5. Subsequently, the flying plate body 5 can be welded and installed by spot welding and then used.
