Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lathe accessory equipment, in particular to a lathe grinding head base. Background Art
[0002] A lathe is a machine tool mainly used for turning and machining rotating workpieces with a turning tool. The function of a lathe is to perform cutting machining on various rotating surfaces and helical surfaces with different sizes and shapes. It mainly uses the rotation of the turning tool to polish and cut the workpiece. Therefore, the turning tool is also the grinding head of the lathe. The turning tool is installed on the tool rest and driven by a motor to rotate at a high speed to process the workpiece.
[0003] According to the patent publication number CN203109250U: The utility model discloses a lathe grinding head base, which includes a base connected to the lathe tool rest. A clamping groove is provided on the upper surface of the base. A grinding head connecting seat is arranged above the base. The grinding head connecting seat is clamped to the base through a strip-shaped boss provided at the bottom. The grinding head connecting seat and the base are connected through an adjusting device, and the adjusting device is connected to a rotating handle provided on one side of the base. The connecting device is a lead screw horizontally arranged on the base. A nut is sleeved on the lead screw. The top of the nut is connected to the grinding head connecting seat. One end of the lead screw extends out of one side of the base and is connected to the rotating handle. The advantages of the utility model are that the lathe grinding head is installed on the grinding head connecting seat, and the base is installed on the tool rest. The structure is reasonable, the installation and use are convenient, and the vibration generated during processing is avoided.
[0004] However, in the above patent, the base and the tool rest need to be fixed by means of threaded connection. During the high-speed rotation of the turning tool during work, centrifugal force will be generated, resulting in the risk of the tool rest and the base becoming disengaged, which is likely to cause the base and the turning tool to fall off. In addition, when the turning tool processes the workpiece, debris will splash outwards. The debris is likely to remain in the connection gap between the base and the turning tool, resulting in the connection gap between the turning tool and the base being stuck by the debris, making the installation and disassembly between the two not smooth. Summary of the Utility Model
[0005] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract of the specification, and the title of the utility model. However, such simplifications or omissions shall not be used to limit the scope of the utility model.
[0006] In view of the problems existing in the above-mentioned existing lathe grinding head base, the present utility model is proposed.
[0007] Therefore, the purpose of the present utility model is to provide a lathe grinding head base, which solves the problems raised in the above-mentioned background technology.
[0008] To solve the above technical problems, the present utility model provides the following technical solutions: A lathe grinding head base, comprising:
[0009] A lathe tool rest, a tool connecting cylinder is fixedly connected to the rotating end of the lathe tool rest, a collar is arranged on the left side of the tool connecting cylinder, a tool is fixedly connected to the left side of the collar, three annularly arrayed clamping grooves are formed in the inner wall of the tool connecting cylinder, the cross section of the clamping groove is zigzag, a plug rod is fixedly connected to the right side of the collar, three annularly arrayed clamping blocks are fixedly connected to the outer wall of the plug rod, the plug rod is inserted into the tool connecting cylinder and the clamping blocks are movably connected with the clamping grooves.
[0010] As a preferred scheme of the lathe grinding head base of the present utility model, wherein: Threads are formed on the outer wall of the tool connecting cylinder, a nut is threadedly connected to the outer wall of the threads, a connecting ring is fixedly connected to the left side of the nut, and the inner ring part of the connecting ring is in fit with the threads. An inclined notch is formed on the left side of the connecting ring. A sealing ring is fixedly connected to the right side of the collar. The middle position of the sealing ring is flush with the right end of the collar. The cross-sectional shape of the connecting ring is stepped and the outer diameter of the left side is the same as the inner diameter of the sealing ring.
[0011] The beneficial effects of the present utility model:
[0012] During use, insert the plug rod into the tool connecting cylinder, and make the clamping blocks insert into the clamping grooves. Push the collar to the right so that the clamping blocks are stuck at the end of the clamping grooves. Then rotate the collar so that the clamping blocks are stuck inside the zigzag part of the clamping grooves, thereby connecting the tool and the collar with the tool connecting cylinder. When the tool is driven by the tool connecting cylinder to rotate at a high speed, the centrifugal force generated makes the clamping blocks only rotate inside the zigzag part of the clamping grooves, thereby preventing the clamping blocks from separating from the clamping grooves, and further preventing the tool and the collar from falling off. Then rotate the nut so that the nut spirally moves along the threads and drives the connecting ring to gradually move towards the collar. Slowly expand the sealing ring through the inclined notch and insert the connecting ring into the inside of the sealing ring, so that the sealing ring seals the connecting part between the tool connecting cylinder and the collar, preventing the chips generated during workpiece processing from entering the inner wall of the tool connecting cylinder and causing the clamping blocks and the clamping grooves to be stuck, thereby avoiding the unsmooth disassembly and assembly of the tool and the collar.

[0019] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings in the specification.
[0020] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.
[0023] Referring Figure 1 , Figure 2 and Figure 4 , the present utility model provides a lathe grinding head base, including:
[0024] A lathe tool rest 1, a rotating end of the lathe tool rest 1 is fixedly connected to a tool connecting cylinder 2. A collar 4 is arranged on the left side of the tool connecting cylinder 2. A tool 3 is fixedly connected to the left side of the collar 4. Three annularly arrayed clamping grooves 25 are formed in the inner wall of the tool connecting cylinder 2. The cross-section of the clamping groove 25 is zigzag. A plug rod 41 is fixedly connected to the right side of the collar 4. Three annularly arrayed clamping blocks 42 are fixedly connected to the outer wall of the plug rod 41. The plug rod 41 is inserted into the tool connecting cylinder 2 and the clamping blocks 42 are movably connected to the clamping grooves 25.
[0025] In the above embodiment, the plug rod 41 is inserted into the tool connecting cylinder 2, and the clamping blocks 42 are inserted into the clamping grooves 25. The collar 4 is pushed to the right, so that the clamping blocks 42 are stuck at the end of the clamping grooves 25. Then the collar 4 is rotated, so that the clamping blocks 42 are stuck inside the zigzag part of the clamping grooves 25, thereby connecting the tool 3 and the collar 4 with the tool connecting cylinder 2. When the tool 3 is driven by the tool connecting cylinder 2 to rotate at a high speed, the centrifugal force generated makes the clamping blocks 42 can only rotate inside the zigzag part of the clamping grooves 25, thereby preventing the clamping blocks 42 from separating from the clamping grooves 25, and further preventing the tool 3 and the collar 4 from falling off.
[0026] Referring Figure 2-3 , the present utility model provides a lathe grinding head base. Threads 21 are formed on the outer wall of the tool connecting cylinder 2. A nut 22 is threadedly connected to the outer wall of the threads 21. A connecting ring 23 is fixedly connected to the left side of the nut 22, and the inner ring part of the connecting ring 23 is in fit with the threads 21. An inclined notch 24 is formed on the left side of the connecting ring 23. A sealing ring 43 is fixedly connected to the right side of the collar 4. The middle position of the sealing ring 43 is flush with the right end of the collar 4. The cross-sectional shape of the connecting ring 23 is stepped and the outer diameter of the left side is the same as the inner diameter of the sealing ring 43.
[0027] In the above embodiments, rotate the nut 22 so that the nut 22 moves spirally along the thread 21 and drives the connecting ring 23 to gradually move towards the collar 4. The sealing ring 43 is slowly expanded through the inclined notch 24 and the connecting ring 23 is inserted into the inside of the sealing ring 43, so that the sealing ring 34 seals the connecting part between the tool holder connecting cylinder 2 and the collar 4, preventing debris generated during workpiece processing from entering the inner wall of the tool holder connecting cylinder 2 and causing jamming between the locking block 42 and the card slot 25, thereby avoiding smooth disassembly and assembly of the tool 3 and the collar 4.
[0028] During use, insert the insertion rod 41 into the tool holder connecting cylinder 2, and make the locking block 42 insert into the card slot 25. Push the collar 4 to the right so that the locking block 42 is stuck at the end of the card slot 25. Then rotate the collar 4 so that the locking block 42 is stuck inside the folded part of the card slot 25, thereby connecting the tool 3 and the collar 4 to the tool holder connecting cylinder 2. When the tool 3 is driven by the tool holder connecting cylinder 2 to rotate at high speed, the centrifugal force generated causes the locking block 42 to only rotate inside the folded part of the card slot 25, thereby preventing the locking block 42 from separating from the card slot 25, and further preventing the tool 3 and the collar 4 from falling off. Then rotate the nut 22 so that the nut 22 moves spirally along the thread 21 and drives the connecting ring 23 to gradually move towards the collar 4. The sealing ring 43 is slowly expanded through the inclined notch 24 and the connecting ring 23 is inserted into the inside of the sealing ring 43, so that the sealing ring 34 seals the connecting part between the tool holder connecting cylinder 2 and the collar 4, preventing debris generated during workpiece processing from entering the inner wall of the tool holder connecting cylinder 2 and causing jamming between the locking block 42 and the card slot 25, thereby avoiding smooth disassembly and assembly of the tool 3 and the collar 4.
[0029] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
