Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to a numerical control machine tool with a process control anti-fooling mechanism. Background Art

[0002] During the processing of a numerical control machine tool, in order to pursue safety, high efficiency and cost savings, especially on a numerical control machine tool with a fixture, often a set of fixtures needs to adapt to the clamping and processing tasks of a workpiece twice or more times. This requires the operator to first correctly clamp the workpiece and then call the corresponding processing program according to the different clamping surfaces of the workpiece. When there are situations of incorrect clamping and wrong selection of the processing program, it is fatal to the machine tool and personal safety. Not only will the expensive cutting tools be damaged, but the machine tool itself will also be severely damaged. Therefore, an anti-fooling mechanism is needed in the control process of the machine tool.

[0003] The patent with the publication number of CN205927890U and the name of a safety anti-fooling device for workpiece processing of a numerical control machine tool discloses a safety anti-fooling device for workpiece processing of a numerical control machine tool. An anti-fooling device is arranged on one side of the fixture. The anti-fooling device includes at least one detection sensor. The detection sensor is installed on one side of the non-processing surface of the processed workpiece through a mounting support plate on the fixture, and the detection sensor is connected to the I / O interface of the machine tool control system through a cable. Since the characteristic positions for anti-fooling detection of different workpieces are different, and the position of the detection switch in this patent is fixed and cannot be applied to the anti-fooling detection of different workpieces to be clamped, the applicability is poor. Therefore, a numerical control machine tool with a process control anti-fooling mechanism is designed now. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a numerical control machine tool with a process control anti-fooling mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A numerical control machine tool with a process control anti-fooling mechanism includes a numerical control machine tool body. Two mounting seats are arranged at the upper end of the numerical control machine tool body. The upper ends of the two mounting seats are fixedly connected with mounting frames. A clamping groove is arranged on the inner bottom wall of the mounting frame. A clamping mechanism is arranged inside the clamping groove. A transverse movement mechanism is arranged on the inner side wall of the mounting frame. A vertical movement mechanism is connected to the transverse movement mechanism. A detection switch is installed on the vertical movement mechanism.

[0007] As a further improvement of the utility model, the clamping mechanism includes a clamping plate arranged inside the clamping groove. A clamping cylinder is fixedly installed on the outer side wall of the mounting frame. The telescopic end of the clamping cylinder penetrates through the mounting frame and is fixedly connected to the side wall of the clamping plate.

[0008] As a further improvement of the present utility model, the transverse movement mechanism includes a first threaded rod disposed inside the installation frame. One end of the first threaded rod is rotatably connected to the inner side wall of the installation frame, and the other end of the first threaded rod is fixedly connected to a first rotating handle. The first rotating handle penetrates the inner side wall of the installation frame and extends to the outside of the installation frame, and the first rotating handle is rotatably connected to the installation frame. A first movable block is threadedly sleeved on the first threaded rod.

[0009] As a further improvement of the present utility model, the vertical movement mechanism includes a mounting bracket fixedly connected to the side wall of the first movable block. A second threaded rod is provided inside the mounting bracket. One end of the second threaded rod is rotatably connected to the inner bottom wall of the mounting bracket, and the other end of the second threaded rod is fixedly connected to a second rotating handle. The second rotating handle penetrates the inner top wall of the mounting bracket and extends to the outside of the mounting bracket, and the second rotating handle is rotatably connected to the mounting bracket. A second movable block is threadedly sleeved on the second threaded rod, and the detection switch is fixedly installed on the side wall of the second movable block.

[0010] As a further improvement of the present utility model, anti-slip lines are provided on the side wall of the clamping plate away from the clamping cylinder.

[0011] As a further improvement of the present utility model, both the first movable block and the second movable block are of a cuboid structure.

[0012] As a further improvement of the present utility model, guide chutes are provided on the inner side wall of the installation frame, and guide sliders are slidably connected inside the guide chutes. The guide sliders are fixedly connected to the side wall of the first movable block.

[0013] As a further improvement of the present utility model, the guide sliders are of a cuboid structure, and the vertical cross-section of the guide chutes is of a rectangular structure.

[0014] As a further improvement of the present utility model, a first locking bolt penetrates the side wall of the installation frame. The first locking bolt is threadedly connected to the installation frame, and the first locking bolt abuts against the first rotating handle. A second locking bolt penetrates the side wall of the mounting bracket. The second locking bolt is threadedly connected to the mounting bracket, and the second locking bolt abuts against the second rotating handle.

[0015] As a further improvement of the present utility model, both the first locking bolt and the second locking bolt are external hexagonal bolts.

[0016] The beneficial effects of the present utility model:

[0017] By setting a lateral movement mechanism, the first threaded rod is driven to rotate by the first rotary handle. Since the first movable block is threadedly connected to the first threaded rod, the first movable block can be made to move laterally. The detection switch is driven to move laterally by the first movable block, and thus the lateral position of the detection switch can be flexibly adjusted.

[0018] By setting a vertical movement mechanism, the second threaded rod is driven to rotate by the second rotary handle. Since the second threaded rod is threadedly connected to the second movable block, the second movable block can be made to move vertically. The detection switch is driven to move vertically by the second movable block, and thus the vertical position of the detection switch can be flexibly adjusted.

[0019] The utility model can flexibly adjust the lateral and vertical positions of the detection switch according to actual needs, and can be applied to the anti-fool operation of different workpieces to be clamped, with higher applicability. BRIEF DESCRIPTION OF THE DRAWINGS
