Description

Technical Field

[0001] The utility model relates to the technical field of turning machine tools, in particular to a turning machine tool with an automatic brake stop structure. Background Art

[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Lathes are the most important type of metal cutting machine tools. In general machine manufacturing factories, lathes are the most numerous and are also called machine tools. Drills, reamer drills, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. The function of a lathe is to perform cutting processing on rotating surfaces of various sizes and shapes, as well as spiral surfaces.

[0003] During the turning process of the machine tool, the rotation of the motor and the contact between the cutting head and the workpiece will be accompanied by vibration. During the turning process, if the cutting head has a small gap or irregular wear during use, it is not easy to be found during inspection, and the cutting head may vibrate during operation, which will affect the accuracy of the workpiece during the processing, causing the quality of the workpiece to decrease and the qualified rate to decrease. It will also inevitably affect the life cycle of the tool and reduce its service life. When the vibration is large and the CNC machine tool is turned off in time, the inertia chuck will still rotate briefly. At this time, if the tool and the workpiece to be processed are not separated in time, it may directly cause damage to the workpiece or severe wear of the tool. Therefore, we propose a turning device with an automatic brake structure. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0028] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In the related art, when the vibration is large and the CNC machine tool is turned off in time, the chuck will still rotate briefly due to inertia. At this time, if the tool and the workpiece to be processed are not separated in time, it may directly cause damage to the workpiece or serious wear of the tool.

[0030] In order to solve the problems in the related technology to a certain extent, an embodiment of the present application provides a turning machine tool with an automatic brake stop structure. When it needs to be shut down and the emergency stop function is activated, the electric push rod moves at the same time, and the brake block 26 and the brake pad 16 are rubbed to cause the rotating shaft 13 to stop quickly.

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figure 1-Figure 5The embodiment of the present application provides a turning machine tool with an automatic brake structure, including a lathe mechanism 1; the lathe mechanism 1 includes: a control box 12 is arranged on the outer wall of the bed 11; a rotating shaft 13 is arranged on the inner wall of the bed 11 and is rotatably connected to the bed 11; a clamping mechanism 14 is arranged at one end of the rotating shaft 13; a turning tool device 15 is arranged on the bed 11; a brake device 2 is arranged on the inner wall of the bed 11, and the brake device 2 includes: a mounting seat 21 is arranged on the inner wall of the bed 11; a fixed seat 22 is arranged at both ends of the mounting seat 21; an electric push rod 23 is arranged on the fixed seat 22; a brake block 26 is arranged on the electric push rod 23.

[0033] When in use, the part to be turned is fixed on the rotating shaft 13 using the clamping mechanism 14, and the rotation is started. Then the turning tool device 15 turns the part. During the turning process, when the sensing device carried by the lathe itself detects abnormal movement and abnormal sound, the emergency stop button on the control box is used to stop the part. The electric push rod 23 is extended at the same time, and the brake block 26 is used for auxiliary braking to prevent the rotating shaft 13 from continuing to rotate and further causing losses. The rotation direction of the rotating shaft 13 is Figure 2 For example, turn clockwise.

[0034] Specifically, the rotating shaft 13, the lathe 11, the turning tool device 15, the control box 12 and the vibration sensing device all belong to the prior art, and the detailed structures are not drawn in the drawings.

[0035] In some embodiments, the ejection end of the electric push rod 23 is provided with a connecting block 24, and the outer wall of the connecting block 24 is provided with a rod body 25 connected to a brake block 26. The inner wall of the brake block 26 is provided with a slide groove 261 that matches the rod body 25. The outer wall of the rod body 25 is sleeved with a spring 27.

[0036] When the electric push rod 23 drives the connecting block 24, the rod body 25 and the brake block 26 to move, the brake block 26 contacts the surface of the rotating shaft 13 to increase the friction force and stop the rotating shaft 13. The brake block 26 can slide on the rod body 25 to adjust its position through the slide groove 261. When sliding, it will squeeze the spring 27 and return to its original position with the help of the spring 27. This design can avoid the brake block 26 from colliding with the rotating shaft 13.

[0037] In some embodiments, the rod body 25 is threadedly connected to the connecting block 24, so that the rod body 25 and the brake block 26 can be easily removed for replacement.

[0038] In some embodiments, the mounting seat 21 is arc-shaped, a fixing hole 211 is provided on the mounting seat 21, and the fixing seat 22 is connected to the bed 11 by bolts. The mounting seat 21 surrounds the rotating shaft and is fixed to the bed 11 by bolts, so that the entire brake device 2 can be easily removed.

[0039] In some embodiments, a brake pad 16 is provided on the outer side wall of the rotating shaft 13, a groove 17 is provided on the outer side wall of the brake pad 16, and a fixing bolt 18 is provided on the inner wall of the groove 17 to connect with the rotating shaft 13. The provision of the brake pad 16 can reduce the wear on the surface of the rotating shaft 13, and the brake pad 16 is fixed on the rotating shaft 13 by the fixing bolt 18, and can be replaced after serious wear.

[0040] In some embodiments, the outer sidewalls of the brake pad 16 and the brake block 26 are provided with a stripe structure. The design of the stripe structure can enhance the friction between the brake pad 16 and the brake block 26.
