Description

Technical Field

[0001] The utility model belongs to the technical field of counterweight sheet processing, and particularly relates to a tool for a lathe for processing counterweight sheets. Background Technique

[0002] At present, most similar tool shanks in the industry adopt tool shanks with non-centered misaligned installed blades. Such tool shanks are only suitable for single-layer processing. Due to the misaligned arrangement of the blades, the tool shank is unevenly stressed, which will cause radial vibration of the tool shank and large aperture deviation, and can only perform rough machining. Therefore, the utility model patent provides a tool shank that can process multiple workpieces simultaneously and improve the aperture accuracy for semi-rough machining. Content of the Utility Model

[0003] The purpose of the utility model is to provide a tool for a lathe for processing counterweight sheets. The utility model provides a tool shank that can process multiple workpieces simultaneously and improve the aperture accuracy for semi-rough machining. While improving the machining efficiency of the machine tool, it also increases the machining accuracy, can effectively improve the production efficiency of the machine tool and achieve mass production, reduces the labor cost, and solves the problem that the existing tool shank adopts a tool shank with non-centered misaligned installed blades. Such a tool shank is only suitable for single-layer processing. Due to the misaligned arrangement of the blades, the tool shank is unevenly stressed, which will cause radial vibration of the tool shank and large aperture deviation, and can only perform rough machining.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model is a tool for a lathe for processing counterweight sheets, including a tool shank. A fixed block is fixedly connected to the left side of the tool shank. Two clamping blades I and two clamping blades II are respectively installed on the right side of the tool shank through screws. A connecting rod is fixedly connected to the left side of the fixed block, and an installation component is arranged on the left side of the fixed block;

[0006] The installation component includes an installation rod. A jack is opened inside the installation rod. A bolt is inserted into the left side of the installation rod. The jack is inserted with the connecting rod. The utility model provides a tool shank that can process multiple workpieces simultaneously and improve the aperture accuracy for semi-rough machining. While improving the machining efficiency of the machine tool, it also increases the machining accuracy, can effectively improve the production efficiency of the machine tool and achieve mass production, reduces the labor cost.

[0007] Furthermore, an installation hole is opened on the right side of the tool shank. A center drill is inserted into the inner wall of the installation hole. The front and back of the center drill and the installation hole are both flat. A threaded hole is opened at the top of the installation hole. Since the front and back of the center drill and the installation hole are both flat, it can play a positioning role during installation, making the installation of the center drill more stable.

[0008] Further, an internal hexagonal bolt II is threadedly connected inside the threaded hole. A conical insertion block is fixedly connected to the bottom of the internal hexagonal bolt II. A conical hole is formed at the top of the center drill. The conical insertion block is adapted to the conical hole. When using a tool to rotate the internal hexagonal bolt II clockwise, the internal hexagonal bolt II drives the conical insertion block to move downward. The conical insertion block then enters the conical hole. The bottom of the internal hexagonal bolt II contacts and fixes with the top of the center drill. By the conical block entering the conical hole, a reinforcement effect can be achieved.

[0009] Further, an inclined groove is formed at the top of the connecting rod. A flat groove is formed on the back surface of the connecting rod. A positioning block is fixedly connected to the back surface of the inner wall of the insertion hole. A receiving groove is formed at the top of the inner wall of the insertion hole. A pushing block is slidably connected to the inner wall of the receiving groove. A limiting ring is fixedly connected to the top of the pushing block. An internal hexagonal bolt I is rotatably connected inside the limiting ring. By providing the installation assembly, specifically when the tool shank collides with the tool or the tool shank is severely worn or damaged after long-term use, the bolt is disassembled, and then the internal hexagonal bolt I is rotated counterclockwise using a tool to make the pushing block enter the receiving groove. Subsequently, the tool shank can be pulled out for disassembly, which can facilitate the disassembly and replacement of the tool shank, thereby reducing the usage cost. It is not necessary to discard the installation rod together, enabling the installation rod to be reused multiple times.

[0010] Further, the outer surface of the internal hexagonal bolt I is threadedly connected to the installation rod. The bottom of the pushing block contacts the inner wall of the inclined groove. The right side of the installation rod contacts the left side of the fixed block. The surface of the inclined groove contacts the front surface of the positioning block. The right side of the bolt penetrates through the connecting rod and extends to the inside. The bolt is threadedly connected to the connecting rod. The pushing block is used to provide the first fixation for the connecting rod, and the bolt is used to provide the second fixation for the connecting rod, which can improve the fixation effect.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model can both process multiple layers of workpieces simultaneously and improve the hole diameter accuracy for semi-rough machining of the tool shank. While improving the machining efficiency of the machine tool, it also increases the machining accuracy, which can effectively improve the production efficiency of the machine tool and achieve mass production, reducing the labor cost.

[0013] 2. By providing the installation assembly, specifically when the tool shank collides with the tool or the tool shank is severely worn or damaged after long-term use, the bolt is disassembled, and then the internal hexagonal bolt I is rotated counterclockwise using a tool to make the pushing block enter the receiving groove. Subsequently, the tool shank can be pulled out for disassembly, which can facilitate the disassembly and replacement of the tool shank, thereby reducing the usage cost. It is not necessary to discard the installation rod together, enabling the installation rod to be reused multiple times.

[0014] Of course, it is not necessary for any product implementing the utility model to simultaneously achieve all the above-mentioned advantages. Brief Description of the Drawings

[0027] The installation assembly 12 includes an installation rod 121. A jack 122 is opened inside the installation rod 121. A bolt 123 is inserted into the left side of the installation rod 121. The jack 122 is inserted with the connecting rod 114. The utility model is a tool shank that can process multiple layers of workpieces simultaneously and can improve the hole diameter accuracy for semi-rough machining. While improving the machining efficiency of the machine tool, it also increases the machining accuracy, can effectively improve the production efficiency of the machine tool and achieve mass production, and reduces the labor cost.

[0028] An installation hole 13 is opened on the right side of the tool shank 1. A center drill 113 is inserted into the inner wall of the installation hole 13. The front and back of the center drill 113 and the installation hole 13 are both flat. A threaded hole 131 is opened at the top of the installation hole 13.

[0029] An internal hexagonal bolt 132 is threadedly connected to the inside of the threaded hole 131. A tapered plug 133 is fixedly connected to the bottom of the internal hexagonal bolt 132. A tapered hole 31 is opened at the top of the center drill 113. The tapered plug 133 is adapted to the tapered hole 31.

[0030] An inclined groove 41 is opened at the top of the connecting rod 114. A flat groove 42 is opened on the back of the connecting rod 114. A positioning block 125 is fixedly connected to the back of the inner wall of the jack 122. A storage groove 124 is opened at the top of the inner wall of the jack 122. A push block 241 is slidably connected to the inner wall of the storage groove 124. A limit ring 242 is fixedly connected to the top of the push block 241. An internal hexagonal bolt 243 is rotatably connected to the inside of the limit ring 242. By setting the installation assembly 12, specifically when the tool shank 1 collides with the tool or the tool shank 1 is severely worn or damaged after long-term use, the bolt 123 is disassembled, and then the internal hexagonal bolt 243 is rotated counterclockwise with a tool to make the push block 241 enter the storage groove 124, and then the tool shank 1 can be pulled out for disassembly, which can facilitate the disassembly and replacement of the tool shank 1, thereby reducing the use cost and not needing to discard the installation rod 121 together, enabling the installation rod 121 to be reused multiple times.

[0031] The outer surface of the socket head cap screw 243 is threadedly connected to the mounting rod 121. The bottom of the push block 241 contacts the inner wall of the inclined slot 41. The right side of the mounting rod 121 contacts the left side of the fixed block 11. The surface of the inclined slot 41 contacts the front surface of the positioning block 125. The right side of the bolt 123 penetrates through the connecting rod 114 and extends into the interior, and the bolt 123 is threadedly connected to the connecting rod 114.

[0032] A specific application of this embodiment is as follows:

[0033] During use, first insert the tool shank 1 into the mounting rod 121 through the connecting rod 114 on the fixed block 11. Then the flat groove 42 on the connecting rod 114 will contact the positioning block 125, which is used for positioning, so that the inclined slot 41 can be aligned with the push block 241 smoothly. Subsequently, use a tool to rotate the socket head cap screw 243 clockwise, so that the push block 241 moves downward and into the inclined slot 41. When the push block 241 contacts the connecting rod 114, it will push the connecting rod 114 to the left, then the fixed block 11 will be in close contact with the right side of the mounting rod 121. Then insert the bolt 123 into the left side of the mounting rod 121 and threadedly connect it to the left side of the connecting rod 114, then the connecting rod 114 can be fixed again, and the tool shank 1 is fixed, completing the installation. When there is a tool collision or the tool shank 1 is severely worn or damaged after long-term use, remove the bolt 123, and then use a tool to rotate the socket head cap screw 243 counterclockwise. Then the socket head cap screw 243 will drive the push block 241 to move upward into the receiving groove 124 through the limiting ring 242, releasing the fixation of the connecting rod 114. Subsequently, pull the tool shank 1 to disassemble it, which can facilitate the disassembly and replacement of the tool shank 1, thereby reducing the use cost. There is no need to discard the mounting rod 121 together, enabling the mounting rod 121 to be reused multiple times. After the tool shank 1 is installed on the mounting rod 121, insert the center drill 113 into the mounting hole 13. Since the front and back surfaces of the center drill 113 and the mounting hole 13 are both flat, it can play a positioning role during installation, making the installation of the center drill 113 more stable. When the left side of the center drill 113 contacts the left inner wall of the mounting hole 13, the tapered hole 31 moves below the tapered insert block 133. Then use a tool to rotate the socket head cap screw 2 132 clockwise, and the socket head cap screw 2 132 drives the tapered insert block 133 to move downward. The tapered insert block 133 then enters the tapered hole 31, and the bottom of the socket head cap screw 2 132 contacts the top of the center drill 113, thereby clamping and fixing the center drill 113 to complete the installation, facilitating the replacement of the center drill 113 alone. Subsequently, install the two indexable inserts 111 and the two indexable inserts 112 on the tool shank 1 respectively. The indexable inserts 111 are located at both ends of the diameter, and the two indexable inserts 112 are stagger-tooth distributed, so that the tool shank 1 can be more evenly stressed when processing the counterweight sheet, and the vibration of the tool shank 1 is reduced, improving the processing accuracy.
