Technical Field

[0001] This utility model relates to the field of cam-type automatic lathe technology, specifically a precision boring tool holder positioning component for a cam-type automatic lathe. Background Technology

[0002] A cam-type automatic lathe is an automated machine tool that controls the machining program through a cam mechanism. It is mainly used for the mass production of precision small parts and features high precision, high efficiency, and low noise. Among these processes, boring is one of the important machining operations on a cam-type automatic lathe, and the accuracy and stability of the tool holder positioning assembly directly affect the quality of the boring operation.

[0003] Traditional tool holder positioning components have several drawbacks: First, their simple structure makes the tool body prone to shifting and wobbling during machining, resulting in poor tool positioning and substandard part quality, leading to a high scrap rate. This not only increases production costs but also affects production efficiency. Second, they are inconvenient to disassemble and maintain. After prolonged use, when the tool holder needs to be replaced due to wear or damage, the disassembly and assembly process of traditional positioning components is cumbersome, consuming a lot of time and manpower, further reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a positioning component for a precision boring tool holder on a cam-type automatic lathe, so as to solve the problems mentioned in the background art, such as poor tool body positioning effect and inconvenience in disassembling and maintaining the tool holder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cam-type automatic lathe precision boring tool holder positioning assembly, including a tool holder and a limiting seat. The tool holder is disposed at the lower end of the limiting seat. Both ends of the tool holder are provided with adjustment cavities, and one end of each adjustment cavity is provided with a slot. One end of the adjustment cavity is connected to a spring, and one end of the spring is fixed with a movable block. A toggle block is fixed to the front end of the movable block. The front end of the adjustment cavity is provided with a clearance groove, and the clearance groove is slidably connected to the rear end of the toggle block. The limiting seat is externally provided with a connecting ring, and both sides of the upper end of the connecting ring are fixed with insert rods. The insert rods are engaged with the slots and the movable blocks. By moving the actuating block outward along the clearance groove, the spring is compressed and the movable block moves to make room for the insert rods. Through the connecting ring, the insert rods are moved upward and inserted into the slots. Then, the actuating block is released, the spring returns to its original position, and the movable block moves and inserts into the insert rods. In this way, the limiting seat is positioned to prevent the threaded groove and threaded post from loosening and to improve the stability of the tool holder and tool body installation.

[0006] As a further technical solution of this utility model, both ends of the limiting seat are provided with sliding grooves, and the sliding grooves are slidably connected to the insertion rod.

[0007] As a further technical solution of this utility model, both ends of the tool holder are provided with a sliding groove, and the sliding groove is slidably connected to the insertion rod. Both the sliding groove and the sliding groove limit the insertion rod to prevent the insertion rod from shifting during movement, thereby better ensuring the stability of the tool holder and the tool body installation.

[0008] As a further technical solution of this utility model, a threaded column is fixed at the upper end of the limiting seat, and a blade body is fixed at the lower end of the limiting seat.

[0009] As a further technical solution of this utility model, a threaded groove is provided in the middle of the lower end of the tool holder, and the threaded groove is threadedly engaged with the threaded column. The threaded column is screwed into the threaded groove, so that the limiting seat and the tool holder are initially connected together.

[0010] As a further technical solution of this utility model, the upper end of the tool holder is provided with a connecting seat, and the two sides and the middle of the connecting seat are respectively provided with a slot and a through hole.

[0011] As a further technical solution of this utility model, both sides of the upper end of the tool holder are fixed with locking blocks, and the locking blocks engage with the slots. The connecting seat is connected to the drive device on the lathe. Through the engagement of the locking blocks and the slots, the tool holder and the connecting seat can be quickly assembled together. Moreover, this locking method ensures a stable connection and prevents loosening.

[0012] As a further technical solution of this utility model, both ends of the through hole are threaded with bolts, and the bolts are threaded with the locking block. The bolts are screwed into the through hole and the locking block respectively to install the tool holder.

[0013] Compared with the prior art, this utility model exhibits significant beneficial effects in several aspects, as follows: First, the initial connection between the limit seat and the tool holder is achieved by screwing the threaded post into the threaded groove. This design not only simplifies the installation process but also improves the reliability of the connection. Building on this, further precise clearance space is provided for the insertion rod by moving the actuating block outward along the clearance groove, which compresses the spring and moves the movable block. The insertion rod is then moved upward and inserted into the slot via the connecting ring. Releasing the actuating block resets the spring, causing the movable block to move and insert into the insertion rod. This series of actions is not only simple to operate but also ensures precise positioning of the limit seat, effectively preventing loosening of the threaded groove and threaded post. This design significantly improves the stability of the tool holder and tool body installation, reducing equipment failures and maintenance costs caused by loose connections.

[0014] Secondly, the design of slides one and two provides double-limiting for the insert rod, preventing it from shifting during movement. This design not only further enhances the stability of the tool holder and tool body installation but also significantly improves the positioning effect of the tool body, ensuring the accuracy and stability of the cutting process. For high-precision machining requirements, this improvement is of irreplaceable importance.

[0015] Furthermore, the connection between the connecting seat and the drive unit on the lathe, along with the snap-fit ​​design of the locking block and slot, enables rapid assembly of the tool holder and the connecting seat. This snap-fit ​​method not only ensures a stable connection and prevents loosening, but also greatly simplifies the installation process and improves production efficiency. Simultaneously, by screwing bolts into the through holes and locking blocks, the installation of the tool holder is further reinforced, ensuring the entire device maintains high stability and reliability during long-term use. This design not only facilitates the disassembly and maintenance of the tool holder but also significantly extends the equipment's service life and reduces maintenance costs.

[0016] In summary, through its ingenious structural design and meticulous attention to detail, this utility model not only excels in improving the stability of the tool holder and tool body installation and ensuring cutting accuracy, but also demonstrates significant positive effects in simplifying installation steps, improving production efficiency, and reducing maintenance costs.

[0021] Please see Figure 1-5 An embodiment of this utility model provides a positioning assembly for a precision boring tool holder of a cam-type automatic lathe, including a tool holder 4 and a limiting seat 9. The tool holder 4 is located at the lower end of the limiting seat 9. Both ends of the tool holder 4 are provided with adjustment cavities 18, and one end of the adjustment cavity 18 is provided with a slot 19. One end of the adjustment cavity 18 is connected to a spring 5, and one end of the spring 5 is fixed with a movable block 17. The front end of the movable block 17 is fixed with a toggle block 15. The front end of the adjustment cavity 18 is provided with a clearance groove 16, and the clearance groove 16 is slidably connected to the rear end of the toggle block 15. A connecting ring 8 is provided on the outside of the limiting seat 9, and two sides of the upper end of the connecting ring 8 are fixed with insert rods 12, and the insert rods 12 are engaged with the slot 19 and the movable block 17. Specifically, such as Figure 1 and Figure 4 As shown, the actuating block 15 is moved outward along the clearance groove 16, causing the spring 5 to compress and the movable block 17 to move, making room for the insertion rod 12. Through the connecting ring 8, the insertion rod 12 is moved upward and inserted into the slot 19. Then, the actuating block 15 is released, the spring 5 returns to its original position, and the movable block 17 moves and inserts into the insertion rod 12. This positions the limiting seat 9, preventing the threaded groove 20 and the threaded post 11 from loosening, and improving the stability of the tool holder 4 and the tool body 10. In addition, to make the sliding between the clearance groove 16 and the actuating block 15 smoother, a smooth coating is provided on the inner wall of the clearance groove 16, which can effectively reduce the friction when the actuating block 15 slides. The spring 5 is made of high-strength and high-elasticity alloy material to ensure that it is not easily deformed during multiple compression and reset processes and always maintains good elastic performance.

[0022] Both ends of the limiting seat 9 are provided with sliding groove 2 7, and sliding groove 2 7 is slidably connected to the insertion rod 12. Both ends of the knife holder 4 are provided with sliding groove 1 6, and sliding groove 1 6 is slidably connected to the insertion rod 12. Specifically, such as Figure 4 and Figure 5 As shown, both slide groove 6 and slide groove 7 limit the insertion rod 12 to prevent it from shifting during movement, thereby better ensuring the stability of the tool holder 4 and the tool body 10.

[0023] The upper end of the limiting seat 9 is fixed with a threaded post 11, the lower end of the limiting seat 9 is fixed with a cutter body 10, and the middle of the lower end of the cutter holder 4 is provided with a threaded groove 20, and the threaded groove 20 is threadedly engaged with the threaded post 11. Specifically, such as Figure 1 and Figure 5 As shown, the threaded post 11 is screwed into the threaded groove 20, so that the limit seat 9 and the tool holder 4 are initially connected together. Since the threaded engagement between the threaded post 11 and the threaded groove 20 has a certain self-locking property, in order to further enhance the stability of the connection.

[0024] The upper end of the tool holder 4 is provided with a connecting seat 2, and the connecting seat 2 is provided with a slot 1 and a through hole 14 on both sides and in the middle respectively. Both sides of the upper end of the tool holder 4 are fixed with a locking block 13, and the locking block 13 is engaged with the slot 1. Specifically, such as Figure 1 and Figure 3 As shown, the connecting seat 2 is connected to the drive device on the lathe. By engaging the locking block 13 with the locking slot 1, the tool holder 4 and the connecting seat 2 can be quickly assembled together. This locking method ensures a stable connection and prevents loosening.

[0025] Both ends of the through hole 14 are threaded with bolts 3, and the bolts 3 are threaded with the locking block 13; Specifically, such as Figure 1 and Figure 2 As shown, screw bolts 3 into the through hole 14 and the locking block 13 respectively to install the tool holder 4.

[0026] Working principle: In use, the connecting seat 2 is connected to the drive device on the lathe. Through the engagement of the locking block 13 and the locking groove 1, the tool holder 4 and the connecting seat 2 can be quickly assembled together. This locking method ensures a stable connection and prevents loosening. Bolts 3 are screwed into the through hole 14 and the locking block 13 to install the tool holder 4. Then, the threaded post 11 is screwed into the threaded groove 20, initially connecting the limiting seat 9 and the tool holder 4. Next, the actuating block 15 is moved outwards along the clearance groove 16, compressing the spring 5 and moving the movable block 17 to make way for the insertion rod 12. The connecting ring 8 moves the insert rod 12 upward and inserts it into the slot 19. Then, the toggle block 15 is released, the spring 5 returns to its original position, and the movable block 17 moves and inserts into the insert rod 12. This positions the limit seat 9, preventing the threaded groove 20 and the threaded post 11 from loosening and improving the stability of the tool holder 4 and the tool body 10. In addition, the first slide groove 6 and the second slide groove 7 both limit the insert rod 12 to prevent it from shifting during movement, thus better ensuring the stability of the tool holder 4 and the tool body 10. In summary, this component has a good positioning effect on the tool body and is easy to disassemble and maintain the tool holder.
