Description

Technical Field

[0001] This utility model relates to the field of lathe technology, specifically to a hydraulic locking and detection mechanism for a CNC lathe turret. Background Technology

[0002] CNC lathes are currently a common piece of equipment in the machining industry and are widely used. The core component of a CNC lathe is the turret. By mounting the cutting tool on the turret's tool head, the lathe can work with the CNC system to complete various rotary machining processes. The turret is a machine tool with its own power source, which can independently provide autonomous movement and feed movement to the cutting tool, thereby completing milling, drilling, and other machining operations. As an important mechanism of mill-turn turning machines, it is not a new product, but has evolved from the tool post of ordinary lathes.

[0003] To prevent the tool head from wobbling and becoming unstable during machining, a locking structure is installed on the tool turret, such as the Chinese utility model patent with publication number CN216858275U. When in use, it can lock the tool head of the tool turret. However, it does not have a detection function. After locking, it cannot detect whether the locking structure has completed the locking work of the tool head. If it is not locked, it cannot be detected in time. During the machining process, the tool head may still become loose and wobbly, affecting the machining accuracy and causing the workpiece to be scrapped.

[0004] Therefore, it is necessary to invent a hydraulic locking and detection mechanism for the turret of a CNC lathe. Summary of the Invention

[0005] Therefore, this utility model provides a hydraulic locking and detection mechanism for the turret of a CNC lathe to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic locking and detection mechanism for a CNC lathe, comprising a housing fixedly connected to the bottom of the turret and multiple protrusions fixedly connected to the turret tool disc, wherein the multiple protrusions are evenly distributed in a circumferential shape and each of the multiple protrusions is provided with a slot.

[0007] A through groove is provided on one side of the housing, and a locking component is provided on the housing for locking the cutter head of the turret. A detection component is also provided inside the housing for detecting whether the locking component has completed the locking work of the cutter head.

[0008] Preferably, the locking component includes a hydraulic cylinder, which is fixedly connected inside the through groove, and a movable rod is slidably embedded on the other side of the housing, with one end of the movable rod fixedly connected to the end of the hydraulic cylinder.

[0009] Preferably, a moving block is fixedly connected to the other end of the moving rod, and a matching locking block is fixedly connected to one side of the moving block.

[0010] Preferably, a stabilizing block is fixedly connected between the hydraulic cylinder and the inner wall of the top of the housing, and a guide shell is fixedly connected to the inner wall of the other side of the housing, with the guide shell slidably sleeved on the upper half of the moving rod.

[0011] Preferably, the detection component includes a bracket, which is fixedly connected to the inner wall of the other side of the housing. A box is fixedly connected to one side of the bracket, and a connecting plate is provided at the bottom of the box. A pressure sensor is fixedly embedded on the connecting plate.

[0012] Preferably, a pressure block is slidably provided inside the housing, a hollow plate is fixedly connected to the inner wall of the housing, a spring is fixedly connected between the hollow plate and the pressure block, and the hollow plate is sleeved on the outside of the pressure sensor.

[0013] Preferably, a convex ball is fixedly connected to the top of the pressure block, and a triangular block is provided on the top of the convex ball for sliding contact with it, and the triangular block is fixedly connected to the bottom of the moving rod.

[0014] Preferably, two mounting blocks are fixedly connected to both the front and rear sides of the housing.

[0015] The beneficial effects of this utility model are as follows: By setting a housing on the turret, and having a locking component and a detection component in the housing, the detection component can detect in time whether the locking component has completed the locking work on the cutter head when the locking component locks the cutter head. Thus, it has a detection function, and can detect in time if it is not locked. In this way, the cutter head will not be loose or shaken during processing, and thus will not affect the processing accuracy or cause the workpiece to be scrapped. Attached Figure Description

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] See attached document Figure 1 - Appendix Figure 7 The present invention provides a hydraulic locking and detection mechanism for a CNC lathe turret, comprising a housing 3 fixedly connected to the bottom of the turret 1 and a plurality of protrusions 4 fixedly connected to the tool disc 2 of the turret 1. The plurality of protrusions 4 are evenly distributed in a circumferential shape, and each of the plurality of protrusions 4 has a slot.

[0028] A through groove is provided on one side of the housing 3. A locking component is provided on the housing 3, which is used to lock the tool disc 2 of the turret 1. A detection component is also provided inside the housing 3, which is used to detect whether the locking component has completed the locking work of the tool disc 2.

[0029] Specifically, the locking component includes a hydraulic cylinder 5, which is fixedly connected inside the through groove. A moving rod 6 is slidably embedded on the other side of the housing 3. One end of the moving rod 6 is fixedly connected to the end of the hydraulic cylinder 5, and the other end of the moving rod 6 is fixedly connected to a moving block 7. A matching locking block 8 is fixedly connected to one side of the moving block 7.

[0030] like Figure 1 As shown, the cutter head 2 of the turret 1 has eight tool mounting points. Similarly, this mechanism has eight protrusions 4, and each protrusion 4 has a slot. When the uppermost tool on the cutter head 2 is located to the right of the workpiece, there is always one protrusion 4 located to the left of the slot 8.

[0031] When it is necessary to lock the cutter head 2, simply control the hydraulic cylinder 5 to move the moving rod 6, moving block 7, and locking block 8 to the left. This allows the locking block 8 to be inserted into the slot, thus locking the cutter head 2. During the locking process, the detection component can promptly detect whether the locking mechanism has completed the locking operation. This provides a detection function, allowing for timely detection of any incomplete locking. This prevents the cutter head 2 from becoming loose or wobbly during machining, thus avoiding any impact on machining accuracy or causing workpiece scrap.

[0032] Specifically, the detection component includes a bracket 11, which is fixedly connected to the inner wall of the housing 3 on the other side. A box 12 is fixedly connected to one side of the bracket 11. A connecting plate 13 is provided at the bottom of the box 12. A pressure sensor 14 is fixedly embedded on the connecting plate 13. A pressure block 15 is slidably provided inside the box 12. A hollow plate 16 is fixedly connected to the inner wall of the box 12. A spring 17 is fixedly connected between the hollow plate 16 and the pressure block 15. The hollow plate 16 is sleeved on the outside of the pressure sensor 14. A convex ball 18 is fixedly connected to the top of the pressure block 15. A triangular block 19 is provided on the top of the convex ball 18 and slides in contact with it. The triangular block 19 is fixedly connected to the bottom of the moving rod 6.

[0033] In use, the triangular block 19 is fixedly connected to the bottom of the moving rod 6. The triangular block 19 can move to the left with the moving rod 6. When it moves to the left, it can squeeze the convex ball 18 and the pressure block 15 to move downward. In this way, the pressure block 15 can contact the pressure sensor 14 and squeeze the pressure sensor 14. Then, the feedback from the pressure sensor 14 can determine whether the cutter head 2 is locked.

[0034] When the pressure block 15 moves downward, it can also squeeze the spring 17, causing the spring 17 to be compressed. When the hydraulic cylinder 5 works and the locking block 8 moves out of the slot, the triangular block 19 will slowly release the pressure on the convex ball 18. Then, under the action of the spring 17, the pressure block 15 can move upward and release the pressure on the pressure sensor 14.

[0035] Specifically, the pressure sensor 14 used in this institution can be connected to a computer via Bluetooth wireless connection, so the feedback from the pressure sensor 14 can be viewed on the computer. In addition, how to make a Bluetooth wireless connection is common knowledge, so it will not be described in detail. Furthermore, the connecting plate 13 is installed at the bottom of the housing 3 with screws, so when the pressure sensor 14 has a problem, the connecting plate 13 and the pressure sensor 14 can be removed to repair or replace the pressure sensor 14.

[0036] In this embodiment, a stabilizing block 9 is fixedly connected between the hydraulic cylinder 5 and the inner wall of the top of the housing 3, and a guide shell 10 is fixedly connected to the inner wall of the other side of the housing 3. The guide shell 10 is slidably sleeved on the upper half of the moving rod 6.

[0037] It should be noted that the stabilizing block 9 can increase the stability between the hydraulic cylinder 5 and the housing 3, and the guide shell 10 can guide the moving rod 6, thereby making it move stably.

[0038] In this embodiment, two mounting blocks 20 are fixedly connected to both the front and rear sides of the housing 3;

[0039] When in use, the design of mounting block 20 allows the entire device to be mounted on a lathe using bolts;

[0040] In this utility model, the model and specifications of the pressure sensor 14 and the hydraulic cylinder 5 need to be selected and determined according to the actual specifications of the entire device. Moreover, the above-mentioned components are very mature products in the prior art, so the specific model and specifications will not be described in detail.

[0041] Furthermore, the oil circuit and hydraulic control of the hydraulic cylinder 5 in this utility model are common knowledge in the field, and since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this utility model.

[0042] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
