Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of numerical control lathes, and particularly relates to a positioning device for numerical control lathe machining. Background Technique
[0002] In the field of numerical control lathe machining, the positioning device is one of the key devices to ensure machining accuracy and efficiency. With the continuous development of modern manufacturing industry, the requirements for machining accuracy and efficiency are increasing day by day. Therefore, higher standards are also put forward for the functions and performances of the positioning device. However, there is a common problem in the currently widely used positioning devices for numerical control lathe machining: the clamping head cannot be replaced flexibly.
[0003] Traditional positioning devices often adopt a fixed clamping head design, which means that once the positioning device is installed on the numerical control lathe, its clamping head is fixed and cannot be replaced according to the different models and sizes of the processed items. This design greatly limits the application range of the positioning device, making it only suitable for specific types or sizes of processed items.
[0004] In the actual machining process, due to the variety of processed items and different models, it is very difficult for the fixed clamping head to meet all machining requirements. For example, when cylindrical workpieces with different diameters or lengths need to be machined, due to the limitation of the clamping head, the traditional positioning device may not be able to effectively clamp and position these workpieces, resulting in a decrease in machining accuracy and even possible safety accidents. Content of the Utility Model
[0005] The purpose of the utility model is to provide a positioning device for numerical control lathe machining to solve the problems put forward in the above background technique.

The two brackets are arranged at the bottom of the workbench, and the two brackets are arranged left and right. The cross beam is arranged between the two brackets. The bidirectional screw is rotatably connected to the two brackets respectively. The motor is arranged on the left bracket, and the driving end of the motor is connected to one end of the bidirectional screw. The two slide rails are arranged on the top of the cross beam. The two moving plates are respectively threadedly connected to the left and right sides of the bidirectional screw, and the bottom parts of the two moving plates are respectively slidably connected to the two slide rails. The two connecting grooves are respectively arranged on the inner sides of the two moving plates. Two fixing components are arranged on the two connecting grooves. The two connecting grooves are connected with two clamping components through the two fixing components.
[0007] Preferably, the clamping member includes a connecting seat and a clamping head. The connecting seat is connected to the clamping head, and the connecting head is movably inserted into the connecting groove. Two clamping grooves are formed on the connecting head.
[0008] Preferably, the fixing assembly includes a fixing frame, a lead screw, two sliding grooves, a movable plate and two clamping blocks. The fixing frame is arranged on the outer top of the connecting groove. The lead screw is rotatably connected to the top of the connecting groove and the top of the fixing frame respectively. The two sliding grooves are respectively arranged on the left and right sides inside the fixing frame. The movable plate is movably connected to the lead screw, and the left and right sides of the movable plate are respectively slidably connected to the two sliding grooves. The two clamping blocks are arranged at the bottom of the movable plate. The two clamping blocks movably penetrate through the top of the connecting groove and are matched with the two clamping grooves.
[0009] Preferably, a positioning frame is arranged on the outer top of the fixing frame. A threaded hole is formed in the top of the positioning frame.

In addition, due to the replaceability of the clamping member, this positioning device can be applied to more types of processed articles, further broadening its application range. At the same time, this also reduces the decline in processing accuracy and potential safety hazards caused by the mismatch of the clamping head, ensuring the safety and stability of the processing process.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0016] Please refer to Figures 1-3 , the present invention provides a positioning device for numerically controlled lathe machining, including a workbench 1, two supports 2, a crossbeam 3, a bidirectional screw 4, a motor 5, two slide rails 6, two moving plates 7, two connecting grooves 8, two fixing components and two clamping components. The two supports 2 are arranged at the bottom of the workbench 1, and the two supports 2 are arranged left and right. The crossbeam 3 is arranged between the two supports 2. The bidirectional screw 4 is rotatably connected to the two supports 2 respectively. The motor 5 is arranged on the left support 2, and the driving end of the motor 5 is connected to one end of the bidirectional screw 4. The two slide rails 6 are arranged on the top of the crossbeam 3. The two moving plates 7 are respectively threadedly connected to the left and right sides of the bidirectional screw 4, and the bottoms of the two moving plates 7 are respectively slidably connected to the two slide rails 6. The two connecting grooves 8 are respectively arranged inside the two moving plates 7. Two fixing components are arranged on the two connecting grooves 8. The two connecting grooves 8 are connected with two clamping components through the two fixing components.
[0017] Specifically, the clamping component includes a connecting seat 9 and a clamping head 10. The connecting seat 9 is connected to the clamping head 10, and the connecting head is movably inserted into the connecting groove 8. Two clamping grooves are arranged on the connecting head.
[0018] Specifically, the fixing component includes a fixing frame 11, a lead screw 12, two chutes 13, a movable plate 14 and two clamping blocks 15. The fixing frame 11 is arranged on the outer top of the connecting groove 8. The lead screw 12 is rotatably connected to the top of the connecting groove 8 and the top of the fixing frame 11 respectively. The two chutes 13 are respectively arranged on the left and right sides inside the fixing frame 11. The movable plate 14 is movably connected to the lead screw 12, and the left and right sides of the movable plate 14 are respectively slidably connected to the two chutes 13. The two clamping blocks 15 are arranged at the bottom of the movable plate 14. The two clamping blocks 15 movably penetrate through the top of the connecting groove 8 and are matched with the two clamping grooves.
[0019] Specifically, a positioning frame 16 is provided on the outer top of the fixing frame 11. A threaded hole is provided at the top of the positioning frame 16. A handle 17 is provided at the top end of the lead screw 12. A positioning hole is provided on the handle 17, and the position of the positioning hole corresponds to that of the threaded hole. A positioning screw 18 is provided in the threaded hole on the positioning frame 16, and the positioning screw 18 movably penetrates through the positioning hole on the handle 17.
[0020] Working principle: When installing the clamping member, insert the connecting seat 9 of the adapted clamping member into the connecting groove 8. Subsequently, the operator rotates the handle 17, and the handle 17 will drive the lead screw 12 to rotate. Due to the limiting effect of the sliding groove 13 on the moving plate 7, the movable plate 14 can only drive the clamping block 15 to move downward in a straight line, so that the clamping block 15 enters the clamping groove of the connecting seat 9. At this time, the clamping member is installed. Subsequently, the operator rotates the positioning screw 18 downward, and the positioning screw 18 will pass through the positioning hole of the handle 17, thereby limiting the handle 17 and improving the stability of the clamping member. After all the clamping members are installed, the operator starts the motor 5, and the driving end of the motor 5 will drive the bidirectional screw 4 to rotate. Due to the limiting effect of the slide rail 6, the two moving plates 7 can only drive the two clamping members to move inward in a straight line, thereby clamping and fixing the workpiece.
