Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a numerical control machining machine tool for three-dimensional bearings. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, represent them in coded numbers, input them into the CNC device through information carriers, and after calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.

[0003] In the prior art, for example, a CNC machine tool for bearing processing disclosed in publication number CN215616433U records: The utility model is provided with a first longitudinal moving component, a second longitudinal moving component and a transverse moving device. Through the cooperation of the first longitudinal moving component, the second longitudinal moving component and the transverse moving device, the transverse or longitudinal movement of the processing drill position can be achieved, which is convenient for processing the bearing.

[0004] In actual use, the above-mentioned device translates the entire device by directly moving the upper frame of the machine tool, thereby moving the processing structure. The displacement of the entire frame will cause the processing structure to shake, so that the position offset of the processing structure is inconsistent with the parameters input on the CNC machine tool, causing errors during processing. In addition, bearing processing not only involves processing in the vertical direction, but the above-mentioned device can only be extended and retracted in the vertical direction and cannot change the processing angle. In addition, bearing processing requires turning over the workpiece, and this operation is usually performed manually by workers. The bearing that has just completed single-sided processing not only has high temperature, but also has sharp waste chips, which poses a safety hazard and can easily cause harm to the operator. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a CNC machining machine for three-dimensional bearings, including an outer frame 1;

[0029] It also includes a processing structure arranged on the upper side of the outer frame 1;

[0030] The processing structure includes a displacement screw 21 arranged on the outer frame 1, a motor fixed to the upper part of the outer frame 1 is installed on one side of the displacement screw 21, a square sleeve 22 installed on the displacement screw 21, the inner side of the square sleeve 22 has a thread meshing with the displacement screw 21, a limit rod 23 fixedly connected to the square sleeve 22, a slider 24 fixedly connected to the end of the limit rod 23, the slider 24 is slidably connected to the slide groove opened in the upper part of the outer frame 1, the limit rod 23 simultaneously connects the square sleeve 22 and the slider 24, the horizontal and vertical limit rods 23 do not intersect, a central block 25 is slidably connected to the limit rod 23, and two circular holes are opened on the central block 25 for two limit rods 23 to pass through respectively.

[0031] A first cylinder telescopic rod 26 is fixedly connected to the lower side of the central block 25. The first cylinder telescopic rod 26 is used to control the lifting and lowering of the processing equipment. A mounting plate 27 is fixedly connected to the lower side of the first cylinder telescopic rod 26. The upper side plate of the mounting plate 27 has a hole for installing the second cylinder telescopic rod 28. The lower side of the mounting plate 27 has a rotating shaft for installing a rotating plate 29. The second cylinder telescopic rod 28 is fixedly connected to the mounting plate 27.

[0032] The lower side of the mounting plate 27 is rotatably connected to a rotating plate 29, and a processing device is installed on the lower side of the rotating plate 29. The processing device can be installed with processing tools such as a cutting knife or a drilling knife. The outer side of the rotating plate 29 is rotatably connected to an adapter block 210, and the adapter block 210 is rotatably connected to the second cylinder telescopic rod 28.

[0033] The lower side of the outer frame 1 is rotatably connected to a base seat 3, and the lower side of the base seat 3 is rotatably connected to the outer frame 1 through an axis. The base seat 3 is heavy and will not rotate due to contact between the processing device and the workpiece. A clamping structure is provided on the inner side of the base seat 3.

[0034] During use, during the displacement of the processing structure, the motor connected to the displacement screw 21 is first started to drive the displacement screw 21 to rotate, thereby moving the square sleeve 22, thereby driving the limit rod 23 to move, wherein the slider 24 provides a supporting force, because the limit rod 23 passes through the central block 25, which will cause the central block 25 to be displaced, thereby controlling the horizontal and vertical movement of the central block 25. When the processing structure needs to move vertically, it is only necessary to start the first cylinder telescopic rod 26 to control the vertical position, the second cylinder telescopic rod 28 and the adapter block 210 are rotationally connected, and the adapter block 210 and the rotating plate 29 are rotationally connected. When the second cylinder telescopic rod 28 is started, the rotating plate 29 will be controlled to rotate on the inner side of the mounting plate 27, so that the processing device can rotate at an angle on the plane, and then cooperate with the base seat 3 to make the base 41 for fixing the workpiece rotate, so that processing at any angle in space can be achieved.

[0035] Example 2

[0036] Reference Figure 1-5 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the clamping structure includes a base 41 arranged on the inner side of the base seat 3, the base 41 is inserted into the base seat 3, a square hole 42 is opened on the base 41, a vertical rod 43 movably connected to the base 41, and a sliding groove is provided in the square hole 42, in which the vertical rod 43 with a sliding block can be slidably connected and prevented from over-extension, and an annular connecting rod 44 fixedly connected to the vertical rod 43, the annular connecting rod 44 is used to connect the two vertical rods 43 so that they can maintain the ability to move simultaneously, and is provided The clamping screw 45 on the vertical rod 43 is meshed with the thread on the inner side of the circular sleeve 47, so that the clamping screw 45 can be freely displaced in the circular sleeve 47. The clamping block 46 arranged on the clamping screw 45 is rotatably connected with the clamping screw 45 through a bearing-like structure to prevent the clamping screw 45 from rotating with the clamping block 46. The clamping block 46 is fixedly connected to the circular sleeve 47 through the telescopic rod 410, so that the clamping block 46 and the circular sleeve 47 can rotate together in the subsequent flipping operation, thereby turning over the clamping bearing.

[0037] The outer side of the clamping screw 45 is threadedly connected to a circular sleeve 47. The outer side of the circular sleeve 47 can be rotatably connected to the vertical rod 43 by setting a bearing-like structure or a slide groove and slide rail. A square groove 48 is opened on the circular sleeve 47. The square groove 48 is opened at both ends of the horizontal position where the vertical rod 43 and the circular sleeve 47 are connected, and is used to lock the workpiece. A pin 49 is set on the circular sleeve 47, and a telescopic rod 410 is fixedly connected to one side of the circular sleeve 47.

[0038] During use, the workpiece is placed in the center position on the base 41, and then the clamping screw 45 is rotated to push the clamping block 46 to contact the workpiece and clamp the workpiece to complete the fixation of the workpiece position. When the workpiece needs to be turned over, it is first necessary to pull up the vertical rod 43, then pull out the pin 49 in the groove 48 above the two vertical rods 43, and then rotate the circular sleeve 47 on the outside of the clamping screw 45. Because there is no restriction between the circular sleeve 47 and the vertical rod 43 at this time, the circular sleeve 47 and the vertical rod 43 can rotate freely. When the circular sleeve 47 rotates 180°, the circular sleeve 47 is fixedly connected to the clamping block 46 by the telescopic rod 410, thereby driving the clamping block 46 to flip, that is, completing the turning operation of the workpiece, and then reinserting the pin 49 into the square groove 48 to complete the fixation of the circular sleeve 47, and then putting down the vertical rod 43 for processing again.

[0039] The remaining structures are the same as those of Example 1.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
