Description

Technical Field

[0001] The utility model relates to the technical field of processing parts of coal mining equipment, in particular to a pin rail wheel gear grinding tool. Background Art

[0002] The AC traction coal mining machine is a new type of electric traction coal mining equipment that is driven by multiple motors, arranged in a horizontal drawer style, and uses an airborne AC frequency conversion speed regulation device. It is used in conjunction with working face conveyors, hydraulic supports, belt conveyors, etc. It can realize the mechanization of mining, loading, and transportation. It has good reliability and can meet the requirements of high-yield and high-efficiency work.

[0003] The coal mining machine is provided with a traction drive part, which is used to control the running speed of the coal mining machine. The traction drive part is arranged at both ends of the coal mining machine and is integrated with the main frame. Each traction drive part is equipped with a pin rail wheel with multiple gear teeth. When working, the pin rail wheel meshes with the pin roller on the working face conveyor. The rotation of the pin rail wheel drives the coal mining machine to run along the working face conveyor. It can be seen that whether the pin rail wheel and the pin roller can mesh correctly directly affects whether the coal mining machine can run stably. The pin rail wheel is a mechanical part similar to a gear. The processing method is generally to first cut the gear teeth on the circular plate, and then clamp the preliminarily processed pin rail wheel on the grinding tool to grind the gear teeth to improve the processing accuracy. The traditional clamping method mainly relies on the pressing action of the cylinder for fixing. However, since multiple gear teeth are distributed on the outer circumference of the pin track wheel, the operator needs to frequently turn the pin track wheel to obtain a more suitable grinding position. At this time, the pin track wheel needs to be clamped repeatedly. The action of controlling the extension and retraction of the cylinder is relatively complicated, and there are certain safety hazards in the process of clamping by the cylinder. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the traditional clamping method for the pin rail wheel is not convenient for quickly adjusting the position of the gear teeth and there are safety hazards. Based on this, the utility model provides a pin rail wheel gear grinding tool that is easy to operate and safe and reliable.

DETAILED DESCRIPTION

[0023] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0024] See also Figure 1-Figure 6 The utility model provides a pin rail wheel gear grinding tool, which is used to clamp and fix the pin rail wheel 100 when grinding the pin rail wheel 100. The pin rail wheel 100 includes a disc body 101 and a plurality of gear teeth 102 evenly distributed on the periphery of the disc body 101. The disc body 101 has a through hole 1011 at the center, and a plurality of threaded holes 1012 are arranged on the disc body 101 at the periphery of the through hole 1011. When in use, the threaded holes 1012 are used to be fixedly connected to the main shaft through bolts. The pin rail wheel gear grinding tool includes a bracket 1, a rotating shaft 2, a positioning disc 3 and a locking nut 4. The rotating shaft 2 is horizontally and rotatably installed on the bracket 1. The positioning disc 3 is sleeved on the rotating shaft 2 and fixed relative to the rotating shaft 2. The positioning disc 3 is used to be fixedly connected to the disc body 101 of the pin rail wheel 100. The locking nut 4 is used to lock the pin rail wheel 100 together with the disc body 101 on the rotating shaft 2.

[0025] Specifically, the bracket 1 includes a bottom plate 11 and a support plate 12, the bottom plate 11 is used to be fixedly connected to a bearing surface (for example, a factory floor), the support plate 12 is vertically arranged, the support plate 12 is fixedly connected to the bottom plate 11, and the support plate 12 and the bottom plate 11 are perpendicular to each other, the rotating shaft 2 is a cylindrical structure, and the rotating shaft 2 is rotatably mounted on the support plate 12. In this embodiment, the support plate 12 and the rotating shaft 2 are connected by a bearing 13, which facilitates the smooth rotation of the rotating shaft 2 and can also effectively support the rotating shaft 2.

[0026] In this embodiment, a reinforcing rib 14 is disposed between the bottom plate 11 and the support plate 2 to improve the connection stability between the bottom plate 11 and the support plate 12 .

[0027] As a preferred embodiment, there are two support plates 12, the two support plates 12 are parallel to each other and arranged at intervals, one end of the rotating shaft 2 passes through one of the support plates 12 and is connected to the other support plate 12. By setting two support plates 12, the supporting strength of the support plates 12 for the rotating shaft 2 is increased.

[0028] See also Figure 2 , Figure 6A limiting edge 21 is convexly provided on the outer circumference of the rotating shaft 2, and the positioning disk 3 is a disk structure with a hole in the center. The hole of the positioning disk 3 cooperates with the rotating shaft 2, and the positioning disk 3 is sleeved on the outside of the rotating shaft 2 through the hole. When the positioning disk 3 is installed into the rotating shaft 2 from the free end of the rotating shaft 2 (that is, the end of the rotating shaft 2 away from the support plate 12) until the positioning disk 3 abuts against the limiting edge 21, the positioning disk 3 is installed in place. In addition, a keyway 22 is provided on the outer circumference of the rotating shaft 2 on the side of the limiting edge 21 away from the support plate 12, and a key 23 is installed in the keyway 22, and the hole of the positioning disk 3 has a groove 31 that cooperates with the key. Through the cooperation between the groove 31 and the keyway 23, the positioning disk 3 cannot rotate relative to the rotating shaft 2, that is, the positioning disk 3 remains fixed relative to the rotating shaft 2 in the circumferential direction.

[0029] The surface of the positioning plate 3 is provided with positioning holes 32 around the hole, and the positioning holes 32 correspond to the threaded holes 1012 on the pin rail wheel 100 to be clamped, and the positioning plate 3 is provided with positioning bolts 33. During installation, the plate body 101 is sleeved on the rotating shaft 2 through the through holes 1011, and one end of the positioning bolt 33 is passed through the positioning hole 32 and then threadedly connected with the threaded hole 1012, thereby fixing the pin rail wheel 100 on the positioning plate 3. It should be noted that a pin rail wheel 100 of a certain specification is used in conjunction with a positioning plate 3 to improve the applicability of the tooling without replacing other parts.

[0030] The end of the rotating shaft 2 away from the limiting edge 21 is a threaded section, and the locking nut 4 is threadedly connected to the threaded section. When the locking nut 4 is tightened until the locking nut 4 abuts against the side of the disk body 101 away from the positioning disk 3, the locking nut 4 cannot be rotated further, and the pin rail wheel 100 is squeezed and fixed between the locking nut 4 and the limiting edge 21, thereby fixing the pin rail wheel 100 on the rotating shaft 2. At this time, the rotation of the rotating shaft 2 will drive the pin rail wheel 100 to rotate synchronously to adjust the position of each gear tooth 102 on the pin rail wheel 100 for easy grinding. In order to facilitate the installation of the positioning disk 3, the threaded section on the rotating shaft 2 is smaller than that of other parts.

[0031] See also Figure 1 , Figure 3On the outer circumferential surface of the rotating shaft 2, a stopper disc 5 is fixedly connected between the limiting edge 21 and the support plate 12. The stopper disc 5 is coaxially arranged with the rotating shaft 2. A stopper pin shaft 6 is slidably installed on the stopper disc 5 along the axial direction of the stopper disc 5. The stopper pin shaft 6 penetrates the stopper disc 5. A plurality of stopper holes 120 are evenly distributed around the central axis of the rotating shaft 2 on the support plate 12 of the bracket 1. The plurality of stopper holes 120 are all located on the same circumference. Any stopper hole 120 can be positioned relative to the stopper pin shaft 6, and the stopper pin shaft 6 can be inserted into the positioned stopper hole 120. The stopper pin shaft 6 and the stopper hole 120 cooperate with each other, so that the stopper pin shaft 6 will not move when inserted into the stopper hole 120. When in use, after the anti-rotation pin shaft 6 is inserted into the anti-rotation hole 120, the anti-rotation wheel disc 5 is locked on the support plate 12. At this time, the anti-rotation wheel disc 5 and the rotating shaft 2 cannot rotate relative to the support plate 12, and the position of the pin rail wheel 100 is locked on the rotating shaft 2, so that the grinding personnel can perform grinding operations; when the anti-rotation pin shaft 6 is pulled out of the anti-rotation hole 120, the locking relationship of the anti-rotation wheel disc 5 is released, and it can rotate relative to the support plate 12. The grinding personnel can rotate the rotating shaft 2 by rotating the anti-rotation wheel disc 5 to adjust the position of each gear 102 on the pin rail wheel 100. When it is rotated to the right position, the anti-rotation pin shaft 6 is reinserted into the anti-rotation hole 120, so as to lock the anti-rotation wheel disc 5 on the support plate 12. In this embodiment, a stop edge 61 is convexly provided at one end of the anti-rotation pin shaft 6 close to the limiting edge 21 to prevent the anti-rotation pin shaft 6 from being separated from the anti-rotation wheel disc 5.

[0032] The pin rail wheel tooth grinding tool of the present invention first sets the positioning plate 3 on the rotating shaft 2, and then fixes the pin rail wheel 100 to be ground on the positioning plate 3, and finally locks the pin rail wheel 100 on the rotating shaft 2 by means of the locking nut 4. When the user wants to adjust the position of the gear teeth 102, he only needs to rotate the anti-rotation wheel plate 5 to a suitable position and lock it on the support plate 12 by means of the anti-rotation pin shaft 6. Only one clamping operation is required. When adjusting the position of the gear teeth 102, only the anti-rotation wheel plate 5 needs to be rotated. Compared with the traditional clamping method, the number of clamping times is reduced, and the operation is safe and fast, thereby improving the processing efficiency.
