Description

Technical Field

[0001] This utility model relates to the field of mechanically clamped boring tools, specifically to a mechanically clamped boring tool that facilitates the flattening of the tool head. Background Technology

[0002] The development of indexable boring tools has gradually evolved with the continuous advancement of machining technology. Early boring tools were mostly integral, with the cutting edge and tool holder being a single unit. This structure meant that once the cutting edge wore down during machining, the entire tool needed to be replaced or reground, wasting material and resulting in low machining efficiency. As industrial production increasingly demanded higher machining accuracy and efficiency, indexable boring tools emerged. By mounting indexable inserts on a tool holder, indexable boring tools allow for replacement of only the insert when its cutting edge wears down, rather than replacing the entire tool, significantly improving tool life and machining efficiency.

[0003] However, in the existing technology, when installing a mechanically clamped boring tool on a lathe, although the mechanically clamped boring tool and the workpiece can be adjusted to be horizontal and vertical, it is difficult to adjust the cutting level of the insert on the mechanically clamped boring tool. If the cutting angle of the insert is lower than the horizontal plane, when the workpiece is being machined, the rotating workpiece will come into contact with the insert, which can easily cause the insert to break. Summary of the Invention

[0004] The purpose of this invention is to provide a machine-clamped boring tool that facilitates tool tip flattening. It has the advantage of adaptively adjusting the cutting horizontal plane of the machine-clamped boring tool, preventing the cutting angle from falling below the horizontal plane and causing the machine-clamped boring tool to break during machining, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machine-clamped boring tool that facilitates tool head flattening, comprising a mounting assembly, an adjustment assembly, and a boring tool assembly. The adjustment assembly is disposed on the mounting assembly for adjusting the horizontal plane of the machine-clamped boring tool's cutting. The boring tool assembly is disposed on the adjustment assembly for assembling and mating the machine-clamped boring tool. The adjustment assembly includes a flipping assembly and a viewing assembly. The flipping assembly is disposed within the mounting assembly, and the viewing assembly is disposed on the flipping assembly. The flipping assembly includes a connecting post, a mating rod, a fixing plate, a counterweight, round holes, bolts, and threaded holes. The connecting post is disposed on the mounting assembly, the mating rod is rotatably mounted on the connecting post, the fixing plate is fixedly mounted on the outer wall of the mating rod, the counterweight is fixedly mounted on the fixing plate, the round holes are evenly distributed on the mounting assembly, the bolts are inserted into the round holes, the threaded holes are evenly distributed on the outer wall of the counterweight, and the bolts are threadedly connected to the threaded holes.

[0006] Furthermore, the fixing plate is fan-shaped, and the counterweight is arc-shaped.

[0007] Furthermore, the mounting assembly includes a tool holder, a mounting plate, and a mounting cover. The mounting plate is fixedly mounted on one end of the tool holder, the mounting cover is fixedly mounted on one outer wall of the mounting plate, the connecting post is fixedly mounted on one outer wall of the mounting plate, and the circular holes are evenly distributed on one outer wall of the mounting plate.

[0008] Furthermore, the viewing component includes a vertical plate, a through-hole, a cylinder, and a level. The vertical plate is fixedly installed on the outer wall of the connecting rod. The through-hole is opened on one side of the outer wall of the mounting cover. The cylinder is fixedly installed on one side of the outer wall of the vertical plate and is slidably connected to the through-hole. The level is fixedly installed on one end of the cylinder.

[0009] Furthermore, the inner wall of the opening is provided with a rounded chamfer, and the opening is provided in the shape of a horseshoe.

[0010] Furthermore, the boring tool assembly includes a mounting groove, a tool holder, an insert, and a retaining bolt. The mounting groove is formed on the connecting rod, the tool holder is inserted into the mounting groove, the insert is mounted on the tool holder by fasteners, and the retaining bolt is threaded onto the connecting rod and the tool holder.

[0011] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0012] This invention utilizes an adjustment component and a counterweight. The weight of the counterweight causes the weight of the connecting rod, on which the tool holder is mounted, to be biased towards the counterweight. The counterweight adaptively adjusts the connecting rod. The counterweight's adjustment and rotation cause the fixing plate to rotate, which in turn causes the connecting rod to rotate. The connecting rod rotates on the connecting column, and in turn, it causes the tool holder and blade to rotate and adjust. Once adjusted, the bolt is pushed into the round hole and rotated into the threaded hole on the counterweight for fixation. If the round hole and the threaded hole are not aligned, the tool holder can be rotated upwards to align them, causing the blade to tilt upwards. This design adaptively adjusts the cutting plane of the clamped boring tool, preventing the cutting angle from falling below the horizontal plane and causing the clamped boring tool to break during machining.

[0013] This utility model, by setting up a boring tool assembly, allows for the easy assembly and replacement of machine-clamped boring tools. The tool is picked up, placed on the tool holder and secured with fasteners, then the tool holder is placed on the mating rod, moved to align with the mounting groove, and then lowered until it slides into the mounting groove. A fixing bolt is then tightened on the mating rod and passes through the tool holder for secure fixing. Finally, the tool holder is placed on the lathe's tool post and secured with fasteners.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides, for example Figures 1-4As shown, a machine-clamped boring tool for easy tool tip flattening includes a mounting assembly 1, an adjustment assembly 2, and a boring tool assembly 3. The adjustment assembly 2 is mounted on the mounting assembly 1 for adjusting the horizontal plane of the machine-clamped boring tool's cutting action. The boring tool assembly 3 is mounted on the adjustment assembly 2 for assembling and mating the machine-clamped boring tool. The adjustment assembly 2 includes a flipping assembly and a viewing assembly. The flipping assembly is located within the mounting assembly 1, and the viewing assembly is located on the flipping assembly. The flipping assembly includes a connecting post 201 and a mating rod 202. The mounting assembly 1 includes a fixed plate 203, a counterweight 204, round holes 205, bolts 206, and threaded holes 207. The connecting column 201 is mounted on the mounting assembly 1. The connecting rod 202 is rotatably mounted on the connecting column 201. The fixed plate 203 is fixedly mounted on the outer wall of the connecting rod 202. The counterweight 204 is fixedly mounted on the fixed plate 203. The round holes 205 are evenly distributed on the mounting assembly 1. The bolts 206 are inserted into the round holes 205. The threaded holes 207 are evenly distributed on the mounting assembly 1. On the outer wall of the counterweight 204, the bolt 206 is threadedly connected to the threaded hole 207. More specifically, due to the weight of the counterweight 204, the weight of the connecting rod 202, on which the tool holder 302 is mounted, is biased towards the counterweight 204. The counterweight 204 adaptively adjusts the connecting rod 202. The counterweight 204 adjusts and rotates, causing the fixing plate 203 to rotate. The fixing plate 203 then causes the connecting rod 202 to rotate, and the connecting rod 202 rotates on the connecting column 201. The connecting rod 202 drives the tool holder 302 and the insert 303 to rotate and adjust. After adjustment, the bolt 206 is pushed into the round hole 205 and rotated into the threaded hole 207 on the counterweight 204 for fixing. If the round hole 205 and the threaded hole 207 are not aligned, the tool holder 302 can be rotated upward to align them, causing the insert 303 to tilt upward. This has the advantage of adaptively adjusting the cutting horizontal plane of the clamped boring tool, preventing the clamped boring tool from breaking during machining due to the cutting angle being lower than the horizontal plane.

[0021] In addition, the fixing plate 203 is fan-shaped and the counterweight 204 is arc-shaped.

[0022] like Figure 1 As shown, in some embodiments, the mounting assembly 1 includes a handle 101, a mounting plate 102, and a mounting cover 103. The mounting plate 102 is fixedly mounted on one end of the handle 101, the mounting cover 103 is fixedly mounted on one side of the outer wall of the mounting plate 102, the connecting post 201 is fixedly mounted on one side of the outer wall of the mounting plate 102, and the circular holes 205 are evenly distributed on one side of the outer wall of the mounting plate 102.

[0023] In some embodiments, the viewing component includes a vertical plate 208, a through-hole 209, a cylinder 210, and a level 211. The vertical plate 208 is fixedly mounted on the outer wall of the connecting rod 202. The through-hole 209 is opened on one side of the outer wall of the mounting cover 103. The cylinder 210 is fixedly mounted on one side of the outer wall of the vertical plate 208. The cylinder 210 is slidably connected to the through-hole 209. The level 211 is fixedly mounted on one end of the cylinder 210.

[0024] In addition, the inner wall of the opening 209 is provided with a rounded chamfer, and the opening 209 is provided in the shape of a horseshoe.

[0025] like Figure 1 As shown, in some embodiments, the boring tool assembly 3 includes a mounting groove 301, a tool holder 302, an insert 303, and a retaining bolt 304. The mounting groove 301 is formed on the connecting rod 202, the tool holder 302 is inserted into the mounting groove 301, the insert 303 is mounted on the tool holder 302 by fasteners, and the retaining bolt 304 is threaded onto the connecting rod 202 and the tool holder 302. More specifically, the insert 303 is picked up and placed on the tool holder 302. 02 is fixed with fasteners. Pick up the tool bar 302 and place it on the docking rod 202. Move the tool bar 302 and place it on the mounting groove 301. Move the tool bar 302 down and slide it into the mounting groove 301. Turn the fixing bolt 304 on the docking rod 202 and pass it through the tool bar 302 to fix it. Place the tool holder 101 on the tool post of the lathe and fix it with fasteners. It has the advantages of splicing and assembling machine-clamped boring tools and facilitating tool replacement.

[0026] Working principle:

[0027] Step 1: Assemble the tool. Pick up the cutting blade 303 and place it on the tool holder 302. Secure it with fasteners. Pick up the tool holder 302 and place it on the docking rod 202. Move the tool holder 302 to the mounting groove 301. Lower the tool holder 302 and slide it into the mounting groove 301. Turn the fixing bolt 304 on the docking rod 202 and through the tool holder 302 to secure it. Place the tool holder 101 on the lathe tool post and secure it with fasteners.

[0028] Step Two: Adjustment and Fixing. When adjusting the cutting horizontal position of the blade 303, the counterweight 204 causes the weight of the connecting rod 202, on which the tool holder 302 is mounted, to be biased towards the counterweight 204. The counterweight 204 adaptively adjusts the connecting rod 202. The counterweight 204 rotates and drives the fixing plate 203 to rotate, which in turn drives the connecting rod 202 to rotate. The connecting rod 202 rotates on the connecting column 201, and in turn, drives the tool holder 302 and the blade 303 to rotate and adjust. After completion, push the bolt 206 into the round hole 205 and rotate it into the threaded hole 207 on the counterweight block 204 for fixing. If the round hole 205 and the threaded hole 207 are not aligned, the tool bar 302 can be rotated upwards to align them, so that the blade 303 tilts upwards. When the connecting rod 202 rotates, the connecting rod 202 drives the vertical plate 208 to rotate. The vertical plate 208 drives the cylinder 210 to slide in the through port 209. The cylinder 210 drives the level 211 to rotate. The staff can observe the level 211 to check whether the blade 303 is in a horizontal state.
