Technical Field
[0001] This utility model relates to the technical field of machining, specifically a limiting mechanism for mining machinery machining. Background Technology
[0002] Mining machinery involves the processing of various parts. Machining refers to the process of changing the shape, size or properties of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing.
[0003] Currently, in the processing of mining parts, limiting devices are used to limit the position of the mining parts to facilitate processing. The limiting devices are usually fastened by tooling fixtures. However, some mining parts are large in size, and it is inconvenient for personnel to adjust the position and angle of the mining parts when they are placed on the table of the tooling fixture. Therefore, we propose a limiting mechanism for mining machinery processing to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a limiting mechanism for mining machinery processing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting mechanism for mining machinery processing, comprising a tooling table, a fixture mounted on the tooling table, a square groove formed on the upper surface of the tooling table, a bearing plate inserted into the square groove, a sliding ball disposed within the bearing plate, a locking component for positioning the sliding ball disposed within the bearing plate, a connecting plate fixedly mounted on the outer side of the bearing plate, the connecting plate inserted into the limiting groove, the limiting groove being formed within the tooling table, a bolt rotatably connected within the limiting groove, the bolt being threadedly connected to the connecting plate, a movable groove formed within the tooling table, a support plate inserted into the movable groove, a threaded rod being threadedly connected to the support plate, an annular plate fixedly mounted on the outer side of the threaded rod, the annular plate being inserted into the annular groove, the annular groove being formed within the tooling table.
[0006] As a further preferred embodiment of this technical solution, the outer side of the bearing plate abuts against the inner wall of the square groove, and the outer side of the sliding ball is on the same horizontal plane as the surface of the tooling table.
[0007] As a further preferred embodiment of this technical solution, the outer side of the support plate abuts against the inner wall of the moving groove, the support plate is located below the bearing plate, and the outer side of the support plate abuts against the bearing plate.
[0008] As a further preferred embodiment of this technical solution, the thread connecting the connecting plate and the bolt is a fine thread, and the ball bearing is made of steel.
[0009] As a further preferred embodiment of this technical solution, the engaging component includes a front block and a rear block, which are inserted into the interior of a groove. The groove is formed on the surface of a support plate. Circular holes are formed on the outer sides of both the front and rear blocks, and a sliding ball is inserted into the interior of each circular hole. The outer side of the sliding ball abuts against the inner wall of the circular hole. A positioning groove is formed on the outer side of the rear block, and a positioning post is inserted into the positioning groove. The positioning post is fixedly set on the outer side of the front block. L-shaped holes are formed on the surfaces of both the front and rear blocks.
[0010] As a further preferred embodiment of this technical solution, anti-slip grooves are provided on the outer sides of both the front block and the rear block, and the anti-slip grooves are evenly distributed on the outer sides of the front block and the rear block.
[0011] As a further preferred embodiment of this technical solution, the lower surface edges of the front block and the rear block are set to be inclined, and the outer sides of the front block and the rear block abut against the inner wall of the groove.
[0012] This utility model provides a limiting mechanism for mining machinery processing, which has the following beneficial effects:
[0013] This invention utilizes the rotation of a bolt within a limiting groove to allow a connecting plate to move upwards from the outside of the bolt to the inside of the limiting groove, thus raising the outer side of the sliding ball above the surface of the tooling table. Subsequently, mining parts can be placed on the outside of the sliding ball for positional adjustment. During this process, the rotation of the threaded rod causes the support plate to move within the moving groove and abut against the lower surface of the carrying plate, thereby providing support for the bottom of the carrying plate. Finally, a clamp is used to hold and limit the position of the mining parts.
[0014] This utility model features a locking mechanism. As the ball bearing undergoes prolonged use, its outer surface will become concave and deformed. Personnel can then remove the front and rear blocks from the groove. Separating the front and rear blocks allows the ball bearing to be removed from the circular hole for replacement. Subsequently, the front and rear blocks can be easily connected through the engagement of the positioning groove and positioning post, and then inserted into the groove for use.

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown in this embodiment, a limiting mechanism for mining machinery processing includes a tooling table 1, a clamp 2 on the tooling table 1, a square groove 3 on the upper surface of the tooling table 1, a bearing plate 4 inserted into the square groove 3, a sliding ball 5 disposed within the bearing plate 4, and a locking component for positioning the sliding ball 5 disposed within the bearing plate 4. A connecting plate 6 is fixedly installed on the outer side of the bearing plate 4, and the connecting plate 6 is inserted into the interior of a limiting groove 7. The limiting groove 7 is located inside the tooling table 1, and a rotating connecting plate 6 is located within the limiting groove 7. A bolt 8 is connected to a connecting plate 6 via threaded engagement. A movable groove 9 is provided within the tooling table 1, and a support plate 10 is inserted into the movable groove 9. A threaded rod 11 is threadedly connected to the support plate 10. An annular plate 12 is fixedly installed on the outer side of the threaded rod 11 and is inserted into an annular groove 13. The annular groove 13 is located inside the tooling table 1. The bolt 8 rotates within a limiting groove 7, allowing the connecting plate 6 to move between the outer side of the bolt 8 and the inside of the limiting groove 7. The support plate 4 moves upward, allowing the outer side of the sliding ball 5 to be higher than the surface of the tooling table 1. The mining part can then be placed on the outer side of the sliding ball 5 for positional adjustment. During this process, the rotation of the threaded rod 11 causes the support plate 10 to move inside the moving groove 9 and abut against the lower surface of the support plate 4, thus supporting the bottom of the support plate 4. Then, the clamp 2 clamps and limits the position of the mining part. The outer side of the support plate 4 abuts against the inner wall of the square groove 3, and the outer side of the sliding ball 5 is at the same level as the surface of the tooling table 1. On the surface, to facilitate subsequent positioning of mining parts by personnel, the outer side of the support plate 10 abuts against the inner wall of the moving groove 9. The support plate 10 is located below the bearing plate 4, and the outer side of the support plate 10 abuts against the bearing plate 4, which can provide support for the bearing plate 4. The thread connecting the connecting plate 6 and the bolt 8 is a fine thread. The slip ball 5 is made of steel and uses a fine thread, which can have self-locking performance, thereby improving the stability of the bearing plate 4 in position.
[0022] like Figure 3 and Figure 4As shown, the engaging component includes a front block 14 and a rear block 15, which are inserted into the interior of a groove on the surface of the support plate 4. Both the front block 14 and the rear block 15 have circular holes 16 on their outer sides, with a sliding ball 5 inserted inside each hole 16. The outer side of the sliding ball 5 abuts against the inner wall of the circular hole 16. The rear block 15 has a positioning groove 17 on its outer side, with a positioning post 18 inserted inside. The positioning post 18 is fixedly mounted on the outer side of the front block 14. Both the front block 14 and the rear block 15 have L-shaped holes 19 on their surfaces. With this engaging component, the outer surface of the sliding ball 5 will become concave and deformed over time. Personnel can then remove the front block 14 and the rear block 15 from the groove, and the engagement between them will be completed. The separation process allows the ball bearing 5 to be removed from the circular hole 16 for replacement. Subsequently, the positioning groove 17 and positioning post 18 facilitate the connection of the front block 14 and the rear block 15, allowing them to be inserted into the groove for use. Both the front block 14 and the rear block 15 have anti-slip grooves 20 on their outer sides, evenly distributed. These grooves facilitate separation and transfer of the front and rear blocks. The lower surface edges of the front and rear blocks 14 are inclined, with their outer sides abutting against the inner wall of the groove, allowing them to be smoothly inserted into the groove.
[0023] This utility model provides a limiting mechanism for mining machinery processing, the specific working principle of which is as follows:
[0024] During operation, the bolt 8 is rotated, causing the connecting plate 6 to rise from outside the bolt 8 and inside the limiting groove 7. This allows the connecting plate 6 to move the bearing plate 4 upward, placing it inside the square groove 3. This ensures that the outer side of the sliding ball 5 is higher than the upper surface of the tooling table 1. Meanwhile, the threaded rod 11 is rotated, allowing the annular plate 12 to rotate within the annular groove 13, and the support plate 10 to move within the moving groove 9, so that the support plate 10 abuts against the lower surface of the bearing plate 4. Subsequently, personnel place the mining parts... At the surface of the tooling table 1, the mining parts can be placed against the outer side of the sliding ball 5, allowing the operator to adjust the position of the mining parts. Then, the position of the mining parts can be limited by the clamp 2. When the outer side of the sliding ball 5 is recessed, the front block 14 and the rear block 15 can be removed from the groove by inserting a hook into the L-shaped hole 19. Then, the front block 14 and the rear block 15 are separated. During this process, the positioning pin 18 moves out of the positioning groove 17, and the operator can then remove the sliding ball 5 from the circular hole 16 for replacement.
[0025] 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.
