Description

Technical Field

[0001] This invention relates to the field of tool holder locking block mold manufacturing and processing technology, and more specifically, to a tool holder locking block mold movable block radius guiding positioning and locking fixture. Background Technology

[0002] During the processing and production of the tool holder locking block mold movable block, it is necessary to position and lock it, which requires the use of locking fixtures to perform the locking operation and achieve the purpose of stabilizing the processing.

[0003] Patent application CN113910504A discloses a radius guiding, positioning, and locking device for tire mold blocks. It includes a control box and a placement platform connected to the top of one side of the control box. A base plate is connected to the bottom of the control box near the placement platform. A processing table is connected to the side of the placement platform away from the control box. A positioning element is provided on the top of the processing table near the placement platform, and a moving platform is provided at the bottom of the processing table. A locking element is installed on the moving platform to clamp and fix the block placed on the processing platform in conjunction with the positioning element. A moving element is provided on the top of the base plate to drive the moving platform to move horizontally on the top of the base plate. The combined use of the positioning element and the locking element in this invention enables rapid and effective positioning of blocks of different radii, while simultaneously locking the blocks, facilitating subsequent processing. Furthermore, this invention allows for fixing the blocks in various placement configurations according to requirements, facilitating processing of multiple sides of the blocks.

[0004] In summary, when locking the movable block, the radius values ​​produced by the curved surface of the movable block with different radii are also different. It is impossible to provide precise support according to the different radii of the curved surface. Therefore, the movable block is prone to displacement during processing, which will also cause the positioning and locking position to shift, resulting in poor locking stability. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a radius-guided positioning and locking fixture for a tool holder locking block mold movable block. The present invention employs a precision positioning component, which can provide precise positioning support based on the precise value of the inner wall radius of the movable block, and provide limiting support on both sides of the tool holder locking block mold movable block, thereby increasing the stability of the tool holder locking block mold movable block, achieving higher positioning accuracy, reducing the likelihood of displacement, and improving stability after positioning, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tool holder locking block mold movable block radius guiding positioning locking fixture, including a concave positioning support plate, wherein a bidirectional transmission screw is installed inside the concave positioning support plate, and a precision positioning component is threadedly connected to the outside of the bidirectional transmission screw;

[0007] The precise positioning component includes a first threaded collar block and a second threaded collar block threadedly connected to the outside of the bidirectional transmission screw. One end of the bidirectional transmission screw is connected to a servo drive motor with coaxial transmission connection. A second limiting support plate is installed at the top of the second threaded collar block and a first limiting support plate is installed at the top of the first threaded collar block. A radius positioning support plate is provided between the second limiting support plate and the first limiting support plate. One end of the radius positioning support plate is connected to a first pushing support plate. A radius measuring scale that is slidably installed with the concave positioning support plate (1) is connected to one side of the first pushing support plate.

[0008] In a preferred embodiment, the second threaded collar block is located on one side of the first threaded collar block, the inner wall threads of the first and second threaded collar blocks are opposite, the two threads on the outer wall of the bidirectional transmission screw are opposite and symmetrical, the second limiting support plate and the first limiting support plate are symmetrically arranged about the radius positioning support plate, the two ends of the first pushing support plate are fixedly connected to the radius positioning support plate and the radius measuring scale respectively, and the other end of the radius positioning support plate is arc-shaped.

[0009] In a preferred embodiment, a pointer block is provided on one side of the radius measuring scale and fixedly connected to the concave positioning support plate. A controller is detachably connected to one side of the concave positioning support plate via multiple self-tapping screws. A support plate is provided on one side of the bidirectional transmission screw and fixedly connected to the concave positioning support plate. A push cap for pushing is connected to one end of the radius measuring scale.

[0010] In a preferred embodiment, a locking mechanism is installed on the inner wall of the radius measuring scale, and the locking mechanism includes a toothed plate installed at the bottom of the radius measuring scale, a plurality of positioning and pressing teeth for upward pushing are installed below the radius measuring scale, the bottom end of the positioning and pressing teeth is connected to a second pushing support plate, and the bottom end of the second pushing support plate is installed with a pushing rod for upward pushing, and a locking cylinder fixedly connected to the concave positioning support plate is installed at the bottom end of the pushing rod.

[0011] In a preferred embodiment, a drive motor and a drive screw are installed inside the radius positioning support plate, with the drive screw located at the output end of the drive motor. A threaded linkage block is threadedly connected to the outside of the drive screw, and a retracting cylinder is fixedly installed at the top of the threaded linkage block. A linkage support rod is fixedly connected to the pushing end of the retracting cylinder, and a collar support plate is sleeved on the outside of the linkage support rod. A downwardly extending linkage pull plate is connected to the collar support plate. The drive screw is threadedly connected to the threaded linkage block, and the drive screw is coaxially driven to the drive motor. Limiting rings are threadedly connected to the outside of the linkage support rod and on both the upper and lower sides of the collar support plate.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. This invention employs a precise positioning component to ensure that when the pushing distance is the same as the inner radius of the tool holder locking block mold movable block, the arc surface of the inner wall of the tool holder locking block mold movable block is in contact with the tip of the radius positioning support plate. The servo drive motor drives the bidirectional transmission screw to rotate, the first threaded collar block moves backward under the action of the thread, and the second threaded collar block moves forward under the action of the thread. The second limiting support plate and the first limiting support plate can be relatively pressed and attached to the left and right sides of the tool holder locking block mold movable block. Precise positioning support can be achieved based on the precise value of the inner radius of the movable block, and limiting support can be provided on both sides of the tool holder locking block mold movable block, increasing the stability of the tool holder locking block mold movable block, improving positioning accuracy, reducing the likelihood of deviation, and improving stability after positioning.

[0014] 2. The present invention uses a locking mechanism to make the locking cylinder drive the push rod to move upward, the push rod drives the second push plate to press upward, and multiple positioning pressing teeth move upward. In this way, the positioning pressing teeth can press at the lower position of the inner wall of the tooth plate. The multiple positioning pressing teeth can press to deform the tooth plate and have an embedded pressing effect, which increases the firmness of the radius measuring scale and makes it less likely to cause the radius measuring scale to shake and affect the reading value.

[0015] 3. In this invention, the starting cylinder drives the linkage rod to move downward, which in turn drives the two limiting and fixing rings to move downward. The linkage pull plate is positioned on one side of the outer wall of the tool holder locking block mold movable block for limiting operation. The drive screw drives the threaded linkage block to move under the action of the thread, thereby fixing the linkage pull plate and the radius positioning support plate to the relative positions of the inner and outer walls of the tool holder locking block mold movable block, which greatly improves the stability of the tool holder locking block mold movable block after locking.

[0016] In summary, through the interaction of the above-mentioned multiple functions, precise positioning and support can be achieved based on the accurate value of the inner wall radius of the movable block, and limiting support can be provided on both sides of the movable block of the tool holder locking block mold. This increases the stability of the movable block of the tool holder locking block mold, resulting in higher positioning accuracy. It also increases the robustness of the radius measuring scale, making it less likely for the radius measuring scale to shake and affect the reading value. This significantly improves the stability of the movable block of the tool holder locking block mold after locking. In conclusion, it is possible to accurately position and lock the movable block of the tool holder locking block mold with different radii, with better positioning stability and robustness.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] As attached Figure 1-6 The tool holder locking block mold movable block radius guiding positioning locking tool shown includes a concave positioning support plate 1, a bidirectional transmission screw 2 installed inside the concave positioning support plate 1, and a precision positioning component threadedly connected to the outside of the bidirectional transmission screw 2.

[0026] The precision positioning component includes a first threaded collar block 3 and a second threaded collar block 4 threadedly connected to the outside of the bidirectional transmission screw 2. One end of the bidirectional transmission screw 2 is connected to a servo drive motor 5 with coaxial transmission connection. A second limiting support plate 7 is installed at the top of the second threaded collar block 4 and a first limiting support plate 6 is installed at the top of the first threaded collar block 3. A radius positioning support plate 8 is provided between the second limiting support plate 7 and the first limiting support plate 6. One end of the radius positioning support plate 8 is connected to a first pushing support plate 9. A radius measuring scale 10 that is slidably installed with the concave positioning support plate (1) is connected to one side of the first pushing support plate 9.

[0027] In some embodiments, as shown in the appendix Figure 1-3 As shown, the second threaded collar block 4 is located on one side of the first threaded collar block 3. The inner threads of the first threaded collar block 3 and the second threaded collar block 4 are opposite. The two threads on the outer wall of the bidirectional transmission screw 2 are opposite and symmetrically arranged, so that the bidirectional transmission screw 2 drives the first threaded collar block 3 to move backward under the action of the threads, and the second threaded collar block 4 moves forward under the action of the threads. The second limiting support plate 7 and the first limiting support plate 6 are symmetrically arranged about the radius positioning support plate 8, so that the first threaded collar block 3 drives the first limiting support plate 6 to move, and the second threaded collar block 4 drives the first threaded collar block 3 to move. The second limiting support plate 7 moves, so that the second limiting support plate 7 and the first limiting support plate 6 can be relatively pressed and fitted against the left and right sides of the tool holder locking block mold movable block. The two ends of the first pushing support plate 9 are fixedly connected to the radius positioning support plate 8 and the radius measuring scale 10 respectively. The other end of the radius positioning support plate 8 is arc-shaped so that the radius measuring scale 10 can drive the first pushing support plate 9 to move the radius positioning support plate 8, forming a linkage effect. One side of the radius positioning support plate 8 is rounded so that it fits against the inner wall of the tool holder locking block mold movable block radius.

[0028] In some embodiments, as shown in the appendix Figure 1 As shown, a pointer block 11 is fixedly connected to a concave positioning support plate 1 on one side of the radius measuring scale 10. A controller 12 is detachably connected to one side of the concave positioning support plate 1 via multiple self-tapping screws, so that the distance pushed by the radius measuring scale 10 can be read by the pointer tip of the pointer block 11. The controller 12 starts the servo drive motor 5 to rotate forward, and the servo drive motor 5 drives the bidirectional transmission screw 2 to rotate. A support plate 13 is fixedly connected to the concave positioning support plate on one side of the bidirectional transmission screw 2, and a push cap 14 for pushing is connected to one end of the radius measuring scale 10, so that pushing the push cap 14 can move the radius measuring scale 10. In this way, when the radius measuring scale 10 moves, the support plate 13 can support the tool holder locking block mold movable block, increasing its stability.

[0029] In some embodiments, as shown in the appendix Figure 3-4 As shown, a locking mechanism is installed on the inner wall of the radius measuring scale 10. The locking mechanism includes a toothed plate 15 installed at the bottom of the radius measuring scale 10, and multiple positioning and pressing teeth 16 for upward pushing are installed below the radius measuring scale 10. The bottom end of the positioning and pressing teeth 16 is connected to a second pushing support plate 17, and the bottom end of the second pushing support plate 17 is equipped with a pushing rod 18 for upward pushing. A locking cylinder 19 fixedly connected to the concave positioning support plate is installed at the bottom end of the pushing rod 18. A control button 20 is provided on the pushing cap 14, and the control button 20 is electrically connected to a solenoid valve for controlling the supply of pressurized gas to the locking cylinder 19.

[0030] When the radius measuring scale 10 moves to the specified precise position, the control button 20 activates the locking cylinder 19, which drives the push rod 18 to move upward. The second push plate 17 drives multiple positioning extrusion teeth 16 to press against the lower position of the inner wall of the toothed plate 15. The multiple positioning extrusion teeth 16 can extrude and deform the toothed plate 15, increasing the firmness of the radius measuring scale 10.

[0031] In some embodiments, as shown in the appendix Figure 6 As shown, a drive motor 22 and a drive screw 23 are installed inside the radius positioning support plate 8. The drive screw 23 is located at the output end of the drive motor 22. A threaded linkage block 24 is threadedly connected to the outside of the drive screw 23. A retracting cylinder 25 is fixedly installed at the top of the threaded linkage block 24. A linkage support rod 26 is fixedly connected to the pushing end of the retracting cylinder 25. A collar support plate 27 is sleeved on the outside of the linkage support rod 26. A downwardly extending linkage pull plate 28 is connected to the collar support plate 27. The drive screw 23 is threadedly connected to the threaded linkage block 24. The drive screw 23 is coaxially driven to the drive motor 22. Limiting rings 21 are threadedly connected to the outside of the linkage support rod 26 and on both sides of the collar support plate 27. That is, the outer wall of the linkage support rod 26 has an external thread, and the inner wall of the limiting ring 21 has an internal thread that matches it.

[0032] When the tip of the radius positioning support plate 8 is attached to the inner wall of the tool holder locking block mold movable block, the downward retraction cylinder 25 is activated to drive the linkage support rod 26 to move downward. The two limiting fixing rings 21 move downward, and the linkage support rod 26 drives the collar support plate 27 to move the linkage pull plate 28 downward. The linkage pull plate 28 is positioned on one side of the outer wall of the tool holder locking block mold movable block for limiting operation. The transmission motor 22 drives the drive screw 23 to drive the threaded linkage block 24 to move under the action of the thread. The downward retraction cylinder 25 causes the linkage support rod 26 to move, so that the linkage pull plate 28 and the radius positioning support plate 8 are fixed at the relative positions of the inner and outer walls of the tool holder locking block mold movable block, which provides better limiting support operation and greatly improves the stability of the tool holder locking block mold movable block after locking.

[0033] Working principle of this invention:

[0034] During positioning and locking, the radius of the inner wall of the tool holder locking block mold movable block can be determined by pushing the push cap 14 to move the radius measuring scale 10. This causes the radius measuring scale 10 to move the first push support plate 9, which in turn moves the radius positioning support plate 8. The distance pushed by the radius measuring scale 10 is read by the pointer block 11. When the distance is the same as the radius of the inner wall of the tool holder locking block mold movable block, the push cap 14 can be stopped. Then, the curved surface of the inner wall of the tool holder locking block mold movable block is placed against the tip of the radius positioning support plate 8. This ensures the radius positioning support plate 8 is precisely positioned against the inner wall of the tool holder locking block mold movable block. Finally, the controller 12 starts the servo drive motor 5 to rotate forward, which in turn drives the bidirectional transmission screw 2 to rotate. The first threaded collar block 3 moves backward under the action of the thread, and the second threaded collar block 4 moves forward under the action of the thread. At the same time, the first threaded collar block 3 drives the first limiting support plate 6 to move, and the second threaded collar block 4 drives the second limiting support plate 7 to move. In this way, the second limiting support plate 7 and the first limiting support plate 6 can be relatively pressed and fitted to the left and right sides of the tool holder locking block mold movable block. This allows for limiting operations on the left and right sides of the tool holder locking block mold movable block. In addition, the radius positioning support plate 8 can support and fix the inner wall of the tool holder locking block mold movable block. It can accurately position and support according to the precise value of the inner wall radius of the movable block, and limit and support the two sides of the tool holder locking block mold movable block, increasing the stability of the tool holder locking block mold movable block.

[0035] When the radius measuring scale 10 is fixed, when the radius measuring scale 10 moves to the specified precise position, the locking cylinder 19 can be activated by pushing the control button 20 on one side of the cap 14. The locking cylinder 19 drives the push rod 18 to move upward, the push rod 18 drives the second push plate 17 to press upward, and the second push plate 17 drives multiple positioning pressing teeth 16 to move upward. In this way, the positioning pressing teeth 16 can press at the position below the inner wall of the tooth plate 15, and the multiple positioning pressing teeth 16 can press to deform the tooth plate 15 and have an embedding pressing effect, increasing the firmness of the radius measuring scale 10 and making it less likely for the radius measuring scale 10 to deviate.

[0036] During the locking operation at the outer wall position of the tool holder locking block mold movable block, when the tip of the radius positioning support plate 8 is in contact with the inner wall of the tool holder locking block mold movable block, the downward retraction cylinder 25 can be activated to drive the linkage support rod 26 to move downward. The linkage support rod 26 drives the two limit fixing rings 21 to move downward, and the linkage support rod 26 drives the collar support plate 27 to move the linkage pull plate 28 downward. In this way, the linkage pull plate 28 is positioned at one side of the outer wall of the tool holder locking block mold movable block for limit operation. Then, the transmission motor 22 is activated to drive the drive screw 23 to advance. When the screw rotates forward, the drive screw 23 drives the threaded linkage block 24 to move under the action of the thread. The threaded linkage block 24 drives the lower retraction cylinder 25 to move the linkage support rod 26. At the same time, the collar support plate 27 drives the linkage pull plate 28 to fit against the outer wall of the tool holder locking block mold movable block. This achieves that the linkage pull plate 28 and the radius positioning support plate 8 are fixed at the relative positions of the inner and outer walls of the tool holder locking block mold movable block, which provides better limit support operation and greatly improves the stability of the tool holder locking block mold movable block after locking.
