Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, and in particular to a boring bar with an anti-vibration tool holder. Background Technology

[0002] Boring tools, as an important type of hole machining tool, are widely used in the field of machining. They play a key role on equipment such as vertical lathes and machining centers. They are mainly used for internal hole machining, hole reaming, and contouring operations. Boring tools are fixed on the machine tool through a boring tool mounting base and are driven to rotate by the machine tool spindle to achieve cutting.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: Boring tools on CNC machine tools are mostly fixed using mounting screws. When they need to be disassembled, replaced, or maintained due to tool wear, changes in machining requirements, operators need to repeatedly disassemble and reassemble the screws. Furthermore, frequent screw disassembly and reassembly can easily lead to wear of the screw holes, reducing the fixing accuracy between the mounting base and the boring tool, thus affecting machining quality. Therefore, to address the above problems, an anti-vibration tool holder boring tool is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, boring tools on CNC machine tools are mostly fixed by mounting screws. When the tool is disassembled, replaced or maintained due to tool wear or changes in processing requirements, the operator needs to repeatedly disassemble and install the screws. At the same time, frequent disassembly and installation of screws can easily lead to wear of screw holes, reduce the fixing accuracy between the mounting base and the boring tool, and thus affect the processing quality. Therefore, a boring tool with an anti-vibration tool holder is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a boring bar with anti-vibration tool holder, comprising a mounting base, a boring bar body slidably connected to the upper surface of the mounting base, a bracket fixedly connected to the upper surface of the mounting base, a guide rod fixedly connected to the inner wall of the bracket, a first slider slidably connected to the arc surface of the guide rod, a threaded rod rotatably connected to the inner wall of the bracket, a round shaft fixedly connected to one end of the threaded rod, a second slider threadedly connected to the arc surface of the threaded rod, a connecting plate fixedly connected to the arc surfaces of the first slider and the second slider, an arc-shaped clamping plate fixedly connected to the lower surface of the connecting plate, and the arc-shaped clamping plate abutting against the arc surface of the boring bar body.

[0006] The effect achieved by the above components is to enable quick installation and removal of the boring bar body on the mounting base. When it is necessary to install and remove the boring bar body on the mounting base, rotating the round shaft drives the threaded rod to rotate, causing the threaded slider to move along the threaded rod. In conjunction with the sliding of another slider on the guide rod, the connecting plate and the arc-shaped clamping plate are raised and lowered, thereby quickly clamping or releasing the boring bar body and improving the clamping efficiency of the boring bar.

[0007] Preferably, an arc-shaped pad is fixedly connected to the arc surface of the arc-shaped clamp, and the arc-shaped pad is made of rubber.

[0008] The effects achieved by the above components are as follows: the curved rubber pad has good elasticity and cushioning performance. When clamping the boring bar body, it can avoid direct rigid contact between the curved clamping plate and the boring bar body, preventing damage such as indentations and scratches on the surface of the boring bar body due to force. At the same time, it enhances the friction, making the boring bar body clamped more securely and reducing the risk of displacement during processing.

[0009] Preferably, the circular arc surface of the circular shaft is provided with a plurality of strip grooves, and the plurality of strip grooves are arranged in a circumferential array.

[0010] The effect achieved by the above components is as follows: the groove increases the friction on the surface of the round shaft, making the contact between the operator's hand and the round shaft more stable and less prone to slippage when the operator rotates the round shaft. This allows for easier and more precise application of force to rotate the round shaft, thereby achieving smooth drive of the threaded rod and improving the operating efficiency when clamping the boring tool body.

[0011] Preferably, the arc surfaces of the first and second sliders are both fixedly connected with ball bearings, and the ball bearings are slidably connected to the inner wall of the bracket.

[0012] The effect achieved by the above components is that the ball bearings greatly reduce the friction between the first and second sliders during their movement on the inner wall of the support, making the movement of the first and second sliders smoother and faster.

[0013] Preferably, the upper surface of the mounting base is provided with a placement groove, a fixing plate is fixedly connected to the upper surface of the mounting base, three round rods are fixedly connected to one side of the fixing plate, and three round grooves are provided at one end of the boring tool body, with the round rods slidably connected to the inner wall of the round grooves.

[0014] The effects achieved by the above components are as follows: the placement slot can accurately position the installation position of the boring bar body, reducing installation errors; the cooperation of multiple round rods and round slots can effectively limit the horizontal movement of the boring bar body, enhance the stability of the boring bar body after installation, and enable the boring bar to withstand greater cutting forces during machining without easily displacing, thereby improving machining accuracy and quality and reducing scrap rate.

[0015] Preferably, an arc-shaped block is fixedly connected to the surface of the mounting base, a circular chamber is fixedly connected to the upper surface of the arc-shaped block, a spring is fixedly connected to the inner wall of the circular chamber, a sliding rod is fixedly connected to the other end of the spring, the sliding rod is slidably connected to the inner wall of the circular chamber, and an arc-shaped baffle is fixedly connected to the end of the sliding rod away from the spring.

[0016] The effect achieved by the above components is that, through the elastic deformation of the spring, the arc-shaped baffle can adaptively press against the boring tool body, preventing the boring tool from shifting forward during the cutting process.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] In this invention, the boring bar body can be quickly installed and removed from the mounting base. When the boring bar body needs to be installed and removed from the mounting base, the rotating shaft drives the threaded rod to rotate, causing the threaded slider to move along the threaded rod. In conjunction with the sliding of another slider on the guide rod, the connecting plate and the arc-shaped clamping plate are raised and lowered, thereby quickly clamping or releasing the boring bar body and improving the clamping efficiency of the boring bar.

[0025] Reference Figures 1-5As shown, this utility model provides a technical solution: a boring bar with an anti-vibration tool holder, including a mounting base 1, a boring bar body 2 slidably connected to the upper surface of the mounting base 1, a bracket 3 fixedly connected to the upper surface of the mounting base 1, a guide rod 4 fixedly connected to the inner wall of the bracket 3, a first slider 5 slidably connected to the arc surface of the guide rod 4, a threaded rod 6 rotatably connected to the inner wall of the bracket 3, a round shaft 11 fixedly connected to one end of the threaded rod 6, a second slider 7 threadedly connected to the arc surface of the threaded rod 6, a connecting plate 8 fixedly connected to the arc surfaces of the first slider 5 and the second slider 7, and an arc-shaped clamping plate 9 fixedly connected to the lower surface of the connecting plate 8. The arc-shaped clamping plate 9 abuts against the arc surface of the boring bar body 2, achieving the effect of quickly assembling and disassembling the boring bar body 2 on the mounting base 1. When installing and removing the boring bar body 2, rotating the round shaft 11 drives the threaded rod 6 to rotate, causing the threaded slider to move along the threaded rod 6. This, combined with the sliding of another slider on the guide rod 4, causes the connecting plate 8 and the arc-shaped clamping plate 9 to rise and fall, thus quickly clamping or releasing the boring bar body 2, improving the clamping efficiency. An arc-shaped pad 10 is fixedly connected to the arc surface of the arc-shaped clamping plate 9. The arc-shaped pad 10 is made of rubber, which has good elasticity and cushioning performance. When clamping the boring bar body 2, it avoids direct rigid contact between the arc-shaped clamping plate 9 and the boring bar body 2, preventing damage such as indentations and scratches on the surface of the boring bar body 2 due to force. It also enhances friction, making the clamping of the boring bar body 2 more stable and reducing the risk of displacement during machining. The arc surface of the round shaft 11... The shaft 11 has several grooves 12 arranged in a circular array. These grooves increase the friction on the surface of the shaft 11, making the contact between the operator's hand and the shaft 11 more stable and less prone to slippage when rotating it. This allows for easier and more precise application of force to rotate the shaft 11, thus achieving smooth drive of the threaded rod 6 and improving the operating efficiency when clamping the boring bar body 2. Both the first slider 5 and the second slider 7 have ball bearings 21 fixedly connected to their arc surfaces. The ball bearings 21 are slidably connected to the inner wall of the bracket 3. The ball bearings 21 greatly reduce the friction between the first slider 5 and the second slider 7 during their movement within the inner wall of the bracket 3, making their movement smoother and more agile. The upper surface of the mounting base 1 has a placement groove 13. A fixing plate 15 is fixedly connected to the upper surface of the boring bar body 2. Three round rods 16 are fixedly connected to one side of the fixing plate 15. Three round grooves 14 are opened at one end of the boring bar body 2. The round rods 16 are slidably connected to the inner wall of the round grooves 14. The placement groove 13 can accurately position the installation position of the boring bar body 2, reducing installation errors. The cooperation of multiple round rods 16 and round grooves 14 can effectively limit the horizontal movement of the boring bar body 2, enhance the stability of the boring bar body 2 after installation, and enable the boring bar to withstand greater cutting forces during processing without easily displacing, thereby improving processing accuracy and processing quality and reducing scrap rate. An arc-shaped block 17 is fixedly connected to the surface of the mounting base 1. A round chamber 18 is fixedly connected to the upper surface of the arc-shaped block 17. A spring 19 is fixedly connected to the inner wall of the round chamber 18.The other end of spring 19 is fixedly connected to a slide rod 22, which is slidably connected to the inner wall of the cylindrical chamber 18. An arc-shaped baffle 20 is fixedly connected to the end of slide rod 22 away from spring 19. Through the elastic deformation of spring 19, the arc-shaped baffle 20 can adaptively press against the boring tool body 2, preventing forward displacement of the boring tool during cutting.

[0026] Working principle: First, the mounting base 1 is fixed on the CNC machine tool. The boring bar body 2 is pushed to slide on the inner wall of the placement groove 13 until the three round blocks at the rear end of the boring bar body 2 are inserted into the inner wall of the round groove 14 on the fixing plate 15. At this time, the operator can rotate the round shaft 11 to drive the second slider 7 to rise and fall on the arc surface of the threaded rod 6. The strip groove 12 optimizes the feel of the rotation operation. Then, the second slider 7 drives the connecting plate 8 and the arc-shaped clamping plate 9 on the connecting plate 8 to rise and fall. The connecting plate 8 drives the first slider 5 to slide on the arc surface of the guide rod 4. The ball bearings 21 on the arc surfaces of the first slider 5 and the second slider 7 slide up and down against the inner wall of the bracket 3, reducing the moving resistance of the first slider 5 and the second slider 7 until the rubber arc pad 10 on the arc clamping plate 9 comes into contact with the boring tool body 2, thereby achieving rapid positioning and clamping of the boring tool body 2. Compared with the traditional screw fixing method, the clamping efficiency is greatly improved. After clamping, its arc baffle 20 uses the elastic force of the spring 19 to adaptively block the boring tool body 2 upward, preventing forward displacement and enhancing the clamping stability in multiple dimensions.
