Description

Technical Field

[0001] This utility model relates to the field of tailstock clamping devices for turning tools, and more particularly to a tailstock clamping device for turning thread cutting tools. Background Technology

[0002] The tailstock clamping device for turning mainly consists of an operating table, a base, a sleeve, and a center. It is a common tailstock clamping device for turning threaded cutting tools.

[0003] Existing technologies, such as the utility model patent with publication number CN204658104U, disclose an automotive cross shaft grinding device. This patent uses a machine tool spindle and machine tool guide rail, and includes a mounting base, floating centers, a clamping sleeve, a nut, a tailstock, a tail tip, and a rotating nut. Compared with the prior art, this automotive cross shaft grinding device places one end of the cross shaft on the right end of the floating center. By manually rotating the rotating nut, the tail tip moves to the left, and the cross shaft is clamped under the combined action of the floating center. The floating center also provides axial positioning for the cross shaft. Then, tightening the nut causes the clamping sleeve to clamp the cross shaft, thereby completing the grinding process. Because this device uses a center for positioning, it avoids the clamping sleeve from clamping the workpiece off-center, thus ensuring the grinding accuracy and preventing workpiece defects and scrap.

[0004] The inventors discovered in their daily work that the replacement of the center point is complicated because existing methods of installing the center point inside the sleeve are based on threaded connections. Furthermore, when disassembling and installing the center point, personnel need to use tools such as wrenches. This disassembly and installation method is very cumbersome, which leads to low efficiency in center point replacement. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing technology uses threaded connections to install the center inside the sleeve, and when disassembling and installing the center, personnel need to use tools such as wrenches to do so. This disassembly and installation method is very cumbersome, which leads to low efficiency in replacing the center. Therefore, a threaded cutting tool tailstock clamping device is proposed.

[0006] To solve the above technical problems, this utility model provides a thread cutting tool tailstock clamping device, including: an operating table and a replacement structure. A base is installed on the upper surface of the operating table, and a sleeve is installed inside the base. A center is installed inside the sleeve via the replacement structure. The replacement structure includes a fixing frame, a positioning hole, and two connecting grooves. The fixing frame is fixedly connected to the sleeve. The positioning hole is opened on the center. Both connecting grooves are opened on the center. A rod is slidably connected to the inner wall of the fixing frame. A locking block is fixedly connected to one end of the rod near the sleeve. A spring is sleeved on the arc surface of the rod. The two ends of the spring are fixedly connected to the locking block and the fixing frame, respectively. The locking block is slidably connected to the sleeve. A positioning plate is slidably connected to the inner wall of the connecting groove. The two positioning plates are fixedly connected to the sleeve. The positioning hole is slidably connected to the locking block.

[0007] The effect achieved by the above-mentioned components is that when personnel need to replace the center, they can move the insert rod to slide the locking block out of the inner wall of the positioning hole, and then move the center until the positioning plate slides out of the inner wall of the connecting groove. This allows for quick replacement of the center and improves the work efficiency of personnel.

[0008] Preferably, a pull ring is fixedly connected to the end of the insertion rod away from the locking block, and the pull ring has a circular cross-section.

[0009] The effect achieved by the above components is that the pull ring makes it easy for personnel to move the plug, which can improve the ease of operation for personnel.

[0010] Preferably, a guide block is fixedly connected to the side of the positioning plate near the top, and the guide block is slidably connected to the connecting groove.

[0011] The effect achieved by the above components is that the guide block can guide the top point, making it easier for personnel to slide the positioning plate into the inner wall of the connecting groove.

[0012] Preferably, the positioning plate is made of stainless steel.

[0013] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the positioning plate from deforming during short-term use.

[0014] Preferably, an auxiliary structure is provided on one side of the operating table. The auxiliary structure includes a limiting frame and a positioning frame. The limiting frame is fixedly connected to the operating table, and the positioning frame is fixedly connected to the base. A motor is fixedly connected to one side of the limiting frame, and the output end of the motor is rotatably connected to the limiting frame. A lead screw is slidably connected to the inner wall of the limiting frame, and the lead screw is fixedly connected to the output end of the motor. A moving block is threadedly connected to the arc surface of the lead screw. A positioning groove is opened on the inner wall of the moving block, and a magnetic block is fixedly connected to the inner wall of the moving block. A fixing rod is fixedly connected to the inner wall of the positioning frame, and a rotating plate is rotatably connected to the arc surface of the fixing rod. An iron block is fixedly connected to the inner wall of the rotating plate.

[0015] The effect achieved by the above-mentioned components is that, when the operator does not need to manually move the seat, the operator first opens the locking device of the seat, then rotates the rotating plate until the rotating plate slides into the inner wall of the positioning groove and the magnetic block and iron block are attracted together. Then, the operator starts the motor to move the seat on the operating table, thereby improving the applicability of the operating table and the convenience of the operator's operation.

[0017] The effect achieved by the above components is that when the rotating plate is not in use, the auxiliary rod can be moved to slide into the inner wall of the limiting hole to limit the rotating plate, which can prevent the rotating plate from rotating and affecting the smoothness of the operator's work during the operation of the operating seat.

[0018] Preferably, the arc surface of the movable rod is fixedly connected with an anti-slip sleeve, and the cross-section of the anti-slip sleeve is a hollow circle.

[0019] The effect achieved by the above-mentioned components is that the anti-slip sleeve can increase the friction between the person's hand and the moving rod, and can prevent the person from slipping during the movement of the moving rod.

[0027] In the embodiments of this utility model, please refer to Figures 2 to 5 The replacement structure 3 includes a fixing frame 32, a positioning hole 36, and two connecting grooves 37. The fixing frame 32 is fixedly connected to the sleeve 5. The positioning hole 36 is opened on the top point 6. Both connecting grooves 37 are opened on the top point 6. The inner wall of the fixing frame 32 is slidably connected to an insert rod 33. The end of the insert rod 33 near the sleeve 5 is fixedly connected to a locking block 31. The arc surface of the insert rod 33 is fitted with a spring 34. The two ends of the spring 34 are fixedly connected to the locking block 31 and the fixing frame 32, respectively. The locking block 31 is slidably connected to the sleeve 5. The inner wall of the connecting groove 37 is slidably connected to a positioning plate 38. The two positioning plates 38 are fixedly connected to the sleeve 5. The positioning hole 36 is slidably connected to the locking block 31. When the tip 6 needs to be replaced, the operator can move the insert rod 33 to slide the locking block 31 out of the inner wall of the positioning hole 36, and then move the tip 6 until the positioning plate 38 slides out of the inner wall of the connecting groove 37. This allows for quick replacement of the tip 6, improving work efficiency. A pull ring 35 with a circular cross-section is fixedly connected to the end of the insert rod 33 away from the locking block 31. The pull ring 35 facilitates movement of the insert rod 33, improving operational convenience. A guide block 39 is fixedly connected to the side of the positioning plate 38 closest to the tip 6, and the guide block 39 is slidably connected to the connecting groove 37. The guide block 39 guides the tip 6, allowing the operator to easily slide the positioning plate 38 into the inner wall of the connecting groove 37. The positioning plate 38 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the positioning plate 38 during short-term use. In the embodiments of this utility model, please refer to Figures 6 to 8The auxiliary structure 4 includes a limiting frame 411 and a positioning frame 401. The limiting frame 411 is fixedly connected to the operating table 1, and the positioning frame 401 is fixedly connected to the base 2. A motor 412 is fixedly connected to one side of the limiting frame 411. The output end of the motor 412 is rotatably connected to the limiting frame 411. A lead screw 414 is slidably connected to the inner wall of the limiting frame 411. The lead screw 414 is fixedly connected to the output end of the motor 412. A moving block 413 is threadedly connected to the arc surface of the lead screw 414. A positioning groove 415 is opened on the inner wall of the moving block 413. A magnetic block 416 is fixedly connected to the inner wall of the moving block 413. A fixing rod 402 is fixedly connected to the inner wall of the positioning frame 401. A rotating plate 403 is rotatably connected to the arc surface of the fixing rod 402. An iron block 404 is fixedly connected to the inner wall of the rotating plate 403. When the operator does not need to manually move the seat 2, the operator first opens the locking device of the seat 2, then rotates the rotating plate 403 until the rotating plate 403 slides into the inner wall of the positioning groove 415 and the magnetic block 416 attracts the iron block 404. Then, the operator starts the motor 412 to move the seat 2 on the operating table 1, thereby improving the applicability of the operating table 1 and the operator's ease of operation. The upper surface of the positioning frame 401 is fixedly connected to the fixing block 406, and the inner wall of the fixing block 406 is slidably connected to the auxiliary rod 407. The end of the auxiliary rod 407 away from the rotating plate 403 is fixedly connected to the moving rod 408. The arc surface of the auxiliary rod 407 is fitted with a compression spring 410, and the two ends of the compression spring 410 are fixedly connected to the fixing block 406 and the auxiliary rod 407 respectively. The inner wall of the rotating plate 403 is provided with a limit hole 405. When the rotating plate 403 is not needed, the auxiliary rod 407 can be moved and slid into the inner wall of the limiting hole 405 to limit the rotating plate 403. This prevents the rotating plate 403 from rotating during operation of the operating seat 2, thus ensuring the smoothness of the operation. An anti-slip sleeve 409 is fixedly connected to the arc surface of the moving rod 408. The anti-slip sleeve 409 has a hollow circular cross-section. The anti-slip sleeve 409 increases the friction between the operator's hand and the moving rod 408, preventing slippage during movement. The working principle of the thread cutting tool tailstock clamping device provided by this utility model is as follows: When the operator needs to replace the center 6, the operator can first use the pull ring 35 to move the insertion rod 33 away from the positioning hole 36. The pull ring 35 facilitates the movement of the insertion rod 33, improving the operator's ease of operation. Then, the insertion rod 33 moves the locking block 31 away from the positioning hole 36. The locking block 31 also causes the spring 34 to retract until the locking block 31 completely slides out of the inner wall of the positioning hole 36. Then, the operator moves the center 6 away from the sleeve 5 until the positioning plate 38 and the guide block 39 completely slide out of the inner wall of the connecting groove 37. The guide block 39 can... The tip 6 serves as a guide, allowing personnel to easily slide the positioning plate 38 into the inner wall of the connecting groove 37. Then, the personnel move the tip 6 that needs to be replaced, causing it to slide into the sleeve 5 and the guide block 39 and positioning plate 38 to slide completely into the inner wall of the connecting groove 37. The positioning plate 38 is made of stainless steel, which has high strength and good wear resistance, preventing deformation of the positioning plate 38 during short-term use. The tip 6 continues until the end near the sleeve 5 abuts against the inner wall of the sleeve 5. At this point, the locking block 31 corresponds to the positioning hole 36. Then, the personnel release the pull ring 35, and the spring 34 rebounds, causing the locking block 31 to move towards the positioning hole 36 until it slides into the inner wall of the positioning hole 36.

[0028] Additionally, when personnel need to move the seat 2 electrically, they can first open the locking device on the seat 2. Then, using the anti-slip sleeve 409, they can move the moving rod 408 away from the fixed block 406. The anti-slip sleeve 409 increases the friction between the personnel's hand and the moving rod 408, preventing slippage during movement. The moving rod 408 then moves the auxiliary rod 407 away from the limiting hole 405. The auxiliary rod 407 moves the compression spring 410 away from the limiting hole 405 until the auxiliary rod 407 slides out of the inner wall of the limiting hole 405. Finally, the personnel can move the rotating plate 40... 3. Rotate the rotating plate 403 to move it closer to the moving block 413. The rotating plate 403 drives the iron block 404 to move closer to the moving block 413 until the rotating plate 403 slides into the inner wall of the positioning groove 415 and the iron block 404 is attracted to the magnetic block 416. Then, the motor 412 is started. The output end of the motor 412 drives the lead screw 414 to rotate. The lead screw 414 drives the moving block 413 to move. The moving block 413 drives the magnetic block 416 and the rotating plate 403 to move. The rotating plate 403 drives the fixed rod 402 to move. The fixed rod 402 drives the positioning frame 401 to move. The positioning frame 401 drives the base 2 to move until the base 2 moves to the appropriate position.
