Abstract
Description
Technical Field
[0001] This utility model belongs to the field of machine tool table splicing technology, specifically relating to a backstop mechanism for anti-collision damping docking and fixing. Background Technology
[0002] Machine tools are commonly used equipment in machining. In milling machines or planers, the workpiece needs to be fixed on the machine tool table. Sometimes, the specifications and dimensions of the machine tool table cannot meet the needs of workpiece fixation, requiring the replacement with a larger worktable. The existing method for replacing the table is table splicing, which involves joining several independent tables together. The splicing of the tables requires locking them to prevent movement during operation, which could affect the workpiece machining effect.
[0003] The prior art patent publication number CN213438632U describes a collision-damping docking and fixing backstop mechanism. This patent includes a base with an integral structure. A fixing plate at both ends of the base has fixing holes. A right-angled trapezoidal inclined block is located in a groove at the top of the base. The groove is parallel to the fixing plate and includes a movable groove and a fixed groove. The depth of the movable groove is greater than the depth of the fixed groove. A buffer connected to the lower right-angle waist of the inclined block is located in a vertical slot on the side of the movable groove away from the fixed groove. This utility model, using the above-described collision-damping docking and fixing backstop mechanism, has a simple structure and can achieve rapid assembly of machine tool tables. However, in practical use, it still has the following shortcomings: From a practical standpoint, this mechanism is fixed to the machine tool table by bolts. Since the table needs frequent installation and disassembly, each bolt needs to be removed individually, which is cumbersome, requires tools, and is time-consuming, reducing work efficiency. Furthermore, the inclined block is frequently subjected to connection impacts and collisions, easily leading to damage. There is a lack of a disassembly mechanism for quick replacement of the inclined block.
[0004] Therefore, a backstop mechanism for anti-collision damping docking and fixing is needed to solve the problems of existing technologies, such as the need to disassemble bolts one by one, which makes installation and disassembly troublesome, requires tools, takes a long time, reduces work efficiency, and lacks a disassembly mechanism for quick replacement of the inclined blocks.

[0005] The purpose of this invention is to provide a collision-resistant damping docking and fixing anti-reverse stop mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a backstop mechanism for anti-collision damping docking and fixing, comprising a base, a connecting plate, a fixing mechanism, a mounting plate, a damper, and a disassembly mechanism. The connecting plate is fixedly connected to the bottom surface of the base, the fixing mechanism is symmetrically arranged around the inside of the connecting plate, the connecting plate and the mounting plate are fixedly connected by the fixing mechanism, the damper is fixedly connected to the inside of the base, and an arc-shaped top block is fixedly connected to the top surface of the damper. The disassembly mechanism is located inside the top groove of the base.
[0007] It should be noted that the fixing mechanism consists of a fixed column, a bidirectional lead screw, a driven wheel, a driving wheel, a rotating rod, a connecting block, a positioning block, and a limiting block. The fixed column is fixedly connected to the inside of the connecting plate, and an installation groove is provided inside the lower part of the fixed column.

The rotating rod is fixedly connected to the lower part of the driving wheel, and the rotating rod is rotatably connected to the fixed column. A turntable is fixedly connected to the bottom surface of the rotating rod.
[0008] It is worth noting that the connecting block is symmetrically threaded onto the outside of the threaded surface of the bidirectional lead screw, and the positioning block is fixedly connected above the connecting block.
[0009] Furthermore, it should be noted that an opening is provided between the mounting groove and the outer surface of the fixing column for the positioning block to pass through, and a through hole of the same size as the fixing column is provided inside the mounting plate, and the limiting block is fixedly connected above the positioning block.
[0010] In a preferred embodiment, the top surface of the mounting groove is provided with a limiting groove that matches the limiting block, and the distance between the positioning block and the connecting plate is the same as the thickness of the mounting plate.
[0011] In a preferred embodiment, the disassembly mechanism consists of a fixed shaft, a first threaded surface, a second threaded surface, a rotating block, and a stop block.

[0014] Compared with the prior art, the anti-collision damping docking and fixing backstop mechanism provided by this utility model has at least the following beneficial effects:
[0015] (1) By setting a fixed mechanism, synchronous clamping is achieved by rotating the bidirectional screw. With the limit design of the positioning block, the connecting plate and the mounting plate are quickly aligned without shaking. The connection between the connecting plate and the mounting plate can be completed quickly without the need for external tools, which improves the overall ease of use and flexibility of the mechanism and increases work efficiency.
[0016] (2) By using the disassembly mechanism, rotating the rotating block can drive the fixed shaft and the backstop block to be disassembled from the groove on the top surface of the base, which facilitates the quick disassembly and replacement of the backstop block, ensures the integrity of the backstop block, and improves the practicality of the overall mechanism.

[0022] The present invention will be further described below with reference to the embodiments.
[0023] Please see Figure 1-4This utility model provides a collision-resistant damping docking and fixing anti-reverse mechanism, including a base 1, a connecting plate 2, a fixing mechanism 3, a mounting plate 4, a damper 5, and a disassembly mechanism 6. The connecting plate 2 is fixedly connected to the bottom surface of the base 1. The fixing mechanism 3 is symmetrically arranged inside the periphery of the connecting plate 2. The connecting plate 2 and the mounting plate 4 are fixedly connected by the fixing mechanism 3. The damper 5 is fixedly connected to the inside of the base 1, and an arc-shaped top block is fixedly connected to the top surface of the damper 5. The disassembly mechanism 6 is arranged inside the top groove of the base 1.
[0024] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the fixing mechanism 3 consists of a fixing column 301, a bidirectional lead screw 303, a driven wheel 304, a driving wheel 305, a rotating rod 306, a connecting block 307, a positioning block 308, and a limiting block 309. The fixing column 301 is fixedly connected to the inside of the connecting plate 2. An installation groove 302 is provided inside the lower part of the fixing column 301. The bidirectional lead screw 303 is rotatably connected to the inside of the installation groove 302. The driven wheel 304 is fixedly connected to the outer side of the middle part of the bidirectional lead screw 303. The driving wheel 305 is located below the driven wheel 304, and the driving wheel 305 and the driven wheel 304 mesh with each other. The rotating rod 306 is fixedly connected to the lower part of the driving wheel 305, and the rotating rod 306 is rotatably connected to the fixing column 301. A turntable is fixedly connected to the bottom surface of the rotating rod 306.
[0025] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting block 307 is symmetrically threaded to the outside of the threaded surface of the bidirectional lead screw 303, and the positioning block 308 is fixedly connected above the connecting block 307.
[0026] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that an opening is provided between the outer surface of the mounting groove 302 and the fixing post 301, allowing the positioning block 308 to pass through. The interior of the mounting plate 4 has a through hole of the same size as the fixing post 301. The limiting block 309 is fixedly connected above the positioning block 308. The top surface of the mounting groove 302 has a limiting groove 310 that matches the limiting block 309. The distance between the positioning block 308 and the connecting plate 2 is the same as the thickness of the mounting plate 4.
[0027] By setting the distance between the positioning block 308 and the connecting plate 2 to be equal to the thickness of the mounting plate 4, gapless clamping can be achieved, thus stably fixing the installation between the connecting plate 2 and the mounting plate 4 and ensuring the stability of the overall structure and the table during impact connection of the machine tool table. By setting the limit block 309 to slide inside the limit groove 310, the positioning block 308 and the connecting block 307 can be restricted from rotating with the bidirectional lead screw 303, thus ensuring that the positioning block 308 makes stable linear motion, thereby stably connecting the mounting plate 4 through the opening.
[0028] As can be seen from the above working process, the fixed mechanism 3 is set up and the bidirectional screw 303 is rotated to achieve synchronous clamping. With the limit design of the positioning block 308, the connecting plate 2 and the mounting plate 4 are quickly aligned without shaking. The connection between the connecting plate 2 and the mounting plate 4 can be completed quickly without the need for external tools, which improves the overall ease of use and flexibility of the mechanism and increases work efficiency.
[0029] Further as Figure 1 and Figure 2 As shown, it is worth noting that the disassembly mechanism 6 consists of a fixed shaft 603, a first threaded surface 604, a second threaded surface 605, a rotating block 606, and a stop block 607. The first threaded groove 601 and the second threaded groove 602 are respectively opened on the left and right sides of the top groove of the base 1. The first threaded surface 604 and the second threaded surface 605 are respectively located on the left and right sides of the fixed shaft 603.
[0030] Further as Figure 1 and Figure 2 As shown, it is worth noting that the first threaded surface 604 and the second threaded surface 605 are respectively engaged with the first threaded groove 601 and the second threaded groove 602.
[0031] Further as Figure 1 and Figure 2 As shown, it is worth noting that the rotating block 606 is fixedly connected to the right end of the fixed shaft 603, and the rotating block 606 has anti-slip grooves evenly distributed on its outer side. The stop block 607 is rotatably connected to the outer side of the middle part of the fixed shaft 603.
[0032] The anti-slip grooves improve the usability of the rotating block 606. By rotating the fixed shaft 603, the installation and removal of the fixed shaft 603 and the groove on the top surface of the base 1 can be completed through the mutual cooperation of the first threaded groove 601, the second threaded groove 602, the first threaded surface 604 and the second threaded surface 605, thus improving the flexibility and convenience of the mechanism.
[0033] This solution includes the following working process: When in use, the fixing mechanism 3 is as shown in the attached diagram when not in use. Figure 4As shown, first align the through hole of the mounting plate 4 with the fixing post 301 on the connecting plate 2, and insert it vertically until the top surface of the mounting plate 4 is in contact with the bottom surface of the connecting plate 2. Rotate the rotating rod 306 via the turntable, driving the driving wheel 305 to rotate, which in turn drives the driven wheel 304 and the double-acting screw 303 to rotate. The rotation of the double-acting screw 303 causes the connecting blocks 307 on both sides to move towards the outer wall of the mounting groove 302, driving the positioning block 308 through the openings on both sides of the mounting groove 302 until the positioning block 308 is flush with the bottom surface of the mounting plate 4, as shown in the attached diagram. Figure 3 As shown, this completes the fixed installation of the connecting plate 2 and the tabletop mounting plate 4. When the tabletop assembly is subjected to impact, the anti-reverse block 607 is impacted and then compresses the damper 5 downward through the arc-shaped top block, causing the damper 5 to deform. Afterward, the damper 5 recovers its deformation and drives the anti-reverse block 607 to rotate. At this time, the anti-reverse block 607 acts as a reverse lock to fix the assembled tabletop. When the anti-reverse block 607 is damaged due to long-term impact, it needs to be replaced. At this time, rotate the rotating block 606 to drive the fixed shaft 603 to rotate, so that the first threaded surface 604 is disengaged from the first threaded groove 601 and the second threaded surface 605 is disengaged from the second threaded groove 602. Pull it out to the right, and continue to rotate the fixed shaft 603 to disengage the first threaded surface 604 from the second threaded groove 602. At this time, the fixed shaft 603 and the anti-reverse block 607 are completely removed, which facilitates the replacement of the anti-reverse block 607. Rotate the rotating block 606 in the opposite direction to install the new fixed shaft 603 and the anti-reverse block 607.
[0034] In summary: The fixed mechanism 3, through the rotation of the bidirectional lead screw 303, achieves synchronous clamping. Combined with the limiting design of the positioning block 308, this ensures rapid and stable alignment of the connecting plate 2 and mounting plate 4, allowing for quick connection without external tools. This enhances the overall ease of use and flexibility of the mechanism, improving work efficiency. Furthermore, the disassembly mechanism 6 allows the rotating block 606 to be rotated, enabling the fixed shaft 603 and the backstop block 607 to be disassembled from the groove on the top surface of the base 1. This facilitates quick disassembly and replacement of the backstop block 607, ensuring its integrity and improving the overall practicality of the mechanism.
