Description

Technical Field

[0001] This invention belongs to the field of boring tools, specifically a multi-purpose deep hole boring head. Background Technology

[0002] Multi-purpose deep hole boring heads, needing to adapt to different machining requirements, often adjust the clearance by adding shims between the tool holder and the mounting slot to ensure stable installation of the tool holder. However, existing technologies for handling shims have several limitations:

[0003] When multiple shims are stacked, the lack of an effective pre-positioning and adjustment mechanism makes them prone to misalignment, resulting in uneven sides after stacking. Traditional limiting structures are mostly rigid and fixed designs, which cannot adapt to the irregular shape of the shims. This leads to insufficient contact between the limiting components and the sides of the shims, making it difficult to correct the misalignment and causing the shims to wobble during boring head operation due to poor limiting effect.

[0004] This shaking can further cause the shim to displace from its preset position, rendering it ineffective in filling the gap between the tool holder and the through slot, thus reducing the stability of the tool holder installation. Instability in the tool holder directly affects the machining accuracy of the boring tool assembly and can even pose safety hazards during high-speed operation.

[0005] Therefore, the present invention provides a multi-purpose deep hole boring head. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The multi-purpose deep hole boring head of the present invention includes a tool holder, a through groove and a boring tool assembly. The tool holder has a through groove inside, a tool holder is installed inside the through groove, and a boring tool assembly is installed inside the tool holder. The bottom wall of the through groove has a bottom groove, and a base is provided on the bottom wall of the bottom groove. A stop block is fixed in the middle position inside the bottom groove, and springs are provided on both sides of the bottom of the base.

[0008] Side blocks are provided on both sides of the top of the base. Multiple pressure plates are evenly spaced inside the side blocks. Movable grooves are opened on both sides inside the base. A sliding rod is fixed inside the movable groove. A slider is slidably provided on the outside of the sliding rod. The slider is fixed on both sides of the bottom of the side block. A spring is wound around the outside of the sliding rod.

[0009] A retractor is rotatably mounted in the middle of the base. A pull rope is wound around the outside of the retractor. The pull rope is led out from both sides of the top of the base and fixed to the rear end of the bottom of the side block. A motor is mounted on the top of the retractor.

[0010] Preferably, the shank of the boring tool assembly is placed in the groove inside the tool holder. Bolt 1 is threadedly connected to both sides of the top of the tool holder. The bottom of bolt 1 extends into the through groove and is pressed tightly against the top of the tool holder. Bolt 2 is threadedly connected to the middle position of one side of the through groove. One end of bolt 2 extends into the groove of the tool holder through the through groove and is pressed tightly against the shank of the boring tool assembly.

[0011] Preferably, the inner bottom wall of the base is provided with a spring groove, a spring is placed in the spring groove, the bottom of the spring is fixedly connected to the inner bottom wall of the spring groove, and a pressure post is fixed to the side wall of the base, the pressure post protruding from the two side walls of the tool holder.

[0012] Preferably, the pressure plates are distributed from top to bottom inside the side block. The end of the pressure plate is provided with a support shell, which is fixed inside the side block. A support block is fixed inside the support shell. A connecting rod is slidably provided inside the support block. One end of the connecting rod protrudes from the end of the support shell and is fixedly connected to the end of the pressure plate. A movable block is provided at one end of the support block. The movable block is fixed outside the connecting rod. A spring is provided between the movable block and the support block.

[0013] Preferably, clamping blocks one and two are provided on both sides of the other end of the support block. Clamping blocks one and two are located on both sides of the connecting rod. Clamping blocks two are fixed inside the support shell. Two adjacent clamping blocks one are connected by a shaft. A sliding plate is provided at the bottom of the side block. The sliding plate is located below clamping blocks one. The top of the sliding plate is connected to clamping blocks one by a shaft. A gear is engaged on one side of the sliding plate. A motor two is provided at the bottom of the gear. The rotating shaft at the top of the motor two is fixedly connected to the rotating shaft at the bottom of the gear.

[0014] The beneficial effects of this invention are as follows:

[0015] The multi-purpose deep hole boring head of this invention, through adaptive adjustment after the pressure plate contacts both sides of the shim, allows for sufficient filling of the uneven sides of the shim. In this way, the limiting part can fully contact both sides of the shim, thereby ensuring the reliability of the limiting effect and avoiding the problem of incomplete limiting due to shim misalignment.

[0016] Secondly, the filling and limiting operation firmly fixes the position of the shim, preventing it from shaking or even falling off during subsequent operations or work. This ensures that the shim can continuously fill the gap between the tool holder and the through groove, thereby avoiding the impact of shim displacement on the installation stability of the tool holder and providing a strong guarantee for the stable installation of the tool holder.

[0017] Furthermore, the tighter fit between components such as shims, side blocks, and tool holders reduces structural loosening caused by shim issues. This provides a more reliable foundation for the normal operation of the boring head, ensuring its stability during operation and improving the overall safety and stability of the equipment.

The pull rope 72 is led out from both sides of the top of the base 4 and fixed to the rear end of the bottom of the side block 5. A motor 7 is mounted on the top of the retractor 71.

[0034] The shank of the boring tool assembly 22 is placed in the groove inside the tool holder 21. Bolt 1 23 is threadedly connected to both sides of the top of the tool holder 1. The bottom of bolt 1 23 extends into the through groove 2 and is pressed tightly against the top of the tool holder 21.

One end of bolt 24 extends from the through groove 2 into the groove of the tool holder 21 and is pressed tightly against the shank of the boring tool assembly 22.

[0035] The inner bottom wall of the base 4 is provided with a spring groove 41, and a spring 42 is placed in the spring groove 41. The bottom of the spring 42 is fixedly connected to the inner bottom wall of the spring groove 41. A pressure column 44 is fixed on the side wall of the base 4, and the pressure column 44 protrudes from the two side walls of the tool holder 1.

[0036] The pressure plates 6 are distributed from top to bottom inside the side block 5. The end of the pressure plate 6 is provided with a support shell 61, which is fixed inside the side block 5. The support block 62 is fixed inside the support shell 61. The connecting rod 63 is slidably arranged inside the support block 62. One end of the connecting rod 63 protrudes from the end of the support shell 61 and is fixedly connected to the end of the pressure plate 6. One end of the support block 62 is provided with a movable block 64, which is fixed outside the connecting rod 63. A spring 65 is provided between the movable block 64 and the support block 62.

[0037] On the other side of the support block 62, there are clamping blocks 1 83 and clamping blocks 2 84. Clamping blocks 1 83 and clamping blocks 2 84 are located on both sides of the connecting rod 63. Clamping blocks 2 84 are fixed inside the support shell 61. Two adjacent clamping blocks 1 83 are connected by a shaft. A sliding plate 8 is provided at the bottom of the side block 5. The sliding plate 8 is located below clamping blocks 1 83. The top of the sliding plate 8 is connected to clamping blocks 1 83 by a shaft. A gear 81 is engaged on one side of the sliding plate 8. A motor 2 82 is provided at the bottom of the gear 81. The rotating shaft at the top of the motor 2 82 is fixedly connected to the rotating shaft at the bottom of the gear 81.

[0038] Working principle:

[0039] The basic installation process of the boring head is as follows: The fixed installation of the boring head follows these steps: First, insert the tool holder 21 into the through groove 2, and press down the top of the tool holder 21 with bolt 23 to fix the tool holder 21 in the through groove 2; then, insert the rod of the boring tool assembly 22 into the groove of the tool holder 21, and use bolt 24 to press the rod of the boring tool assembly 22 tightly to complete the fixing of the boring tool assembly 22 and the tool holder 21. This completes the overall installation of the boring head.

[0040] The basic installation process of the boring head is as follows: The fixed installation of the boring head follows these steps: First, insert the tool holder 21 into the through groove 2, and press down the top of the tool holder 21 with bolt 23 to fix the tool holder 21 in the through groove 2; then, insert the rod of the boring tool assembly 22 into the groove of the tool holder 21, and use bolt 24 to press the rod of the boring tool assembly 22 tightly to complete the fixing of the boring tool assembly 22 and the tool holder 21. This completes the overall installation of the boring head.

[0041] Furthermore,

[0042] Gasket installation and limit fixing process:

[0043] I. Initial adjustment of base 4 and side block 5:

[0044] When the tool holder 21 is inserted into the through slot 2, it will press down on the side block 5, making the base 4 tightly adhere to the bottom wall of the bottom slot 3. At this time, the spring 42 at the bottom of the base 4 will contract under pressure to store energy; the base 4 can also be pushed to the above-mentioned tight position by pressing down on the pressure column 44. At the same time, the motor 7 drives the winding reel 71 to wind the pull rope 72, pulling the side block 5 to the top sides of the base 4. When the side block 5 moves, it drives the slider 53 to slide outside the slide rod 52, and pulls the spring 54 to extend and store energy.

[0045] II. Placement and initial positioning of the gasket:

[0046] When installing the shims, first press down the pressure column 44 to move the base 4 down to be in close contact with the bottom wall of the bottom groove 3, and put the required number of shims on the top of the stop block 43; after releasing the pressure column 44, the spring 42 releases energy to push the base 4 up, pushing the top of the side block 5 to be in contact with the bottom wall of the tool holder 21, so that the side block 5 is located on both sides of the shims.

[0047] 3. Side block 5 moves closer to the gasket:

[0048] When the motor is started, the pull rope 72 is released. At the same time, the spring 54 releases energy to push the slider 53 to move, so that the two side blocks 5 move closer to the sides of the pad.

[0049] IV. Treatment of misaligned gaskets on pressure plate 6:

[0050] If the stacked gaskets are misaligned, when the side block 5 moves, the pressure plate 6 contacts the two sides of the gasket and moves under pressure, which drives the connecting rod 63 to move within the support block 62. The movable block 64 moves along with it and squeezes the spring 65 to retract. The spring 65 pushes the movable block 64 back, so that the pressure plate 6 is in close contact with the side wall of the gasket, thus solving the problem of unevenness on both sides of the gasket.

[0051] V. The function of the clamping and securing pressure plate 6:

[0052] The start motor 82 drives the gear 81 to move the moving plate 8, so that the clamping block 83 on one side of the connecting rod 63 and the clamping block 84 cooperate to clamp the connecting rod 63, ensuring the filling and clamping effect of the pressure plate 6 on both sides of the gasket.

[0053] For the pads that may be misaligned or uneven on both sides after stacking, the filling and limiting function can firstly effectively correct the misalignment of the pads. Through the adaptive adjustment after the pressure plate 6 contacts the sides of the pads, the uneven sides of the pads are filled, so that the limiting part can fully contact the sides of the pads, ensuring the reliability of the limiting effect.

[0054] Secondly, the position of the gasket can be stabilized and limited to prevent the gasket from shaking or even falling off during subsequent operations or work, thereby ensuring that the gasket can continue to fill the gap between the tool holder 21 and the through groove 2, and avoid affecting the installation stability of the tool holder 21 due to the displacement of the gasket.

[0055] In addition, this filling and limiting treatment can further enhance the stability of the overall structure, making the fit between components such as the shim, side block 5, and tool holder 21 tighter, reducing structural loosening caused by shim problems, and providing a more reliable foundation for the normal operation of the boring head.
