Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing fixtures, in particular to an anti-deviating precision machine tool processing positioning device. Background Art

[0002] Machine tools refer to machines that manufacture machines. Parts with high precision requirements and fine surface roughness requirements in modern mechanical manufacturing generally need to be processed by cutting methods on machine tools. Machine tool fixtures are devices used to clamp workpieces and guide tools on machine tools. They are in contact with the positioning reference of the workpiece and are used to determine the correct position of the workpiece in the fixture, thereby ensuring the relative correct position of the workpiece relative to the tool and the machine tool processing movement during processing.

[0003] When existing machine tools process workpieces, they generally position and fix the workpieces by clamping them on the left and right sides. The fixing method is relatively simple. When the machine tool processes metal workpieces, the force applied by the tool is large. The metal workpiece is prone to vibrate on the machine tool. The vibration can easily cause the workpiece to move up and down, causing the parts to shift, thereby affecting the processing accuracy of the parts. Utility Model Content

[0028] Reference Figure 1-3 The invention discloses an anti-drift precision machine tool processing positioning device, which is used for positioning and fixing workpieces in machine tool processing, in order to increase the stability of workpiece fixation and avoid the workpiece from drifting during processing.

[0029] The anti-deviating precision machine tool processing positioning device comprises a base 1 and a plurality of fixing mechanisms, a workpiece 13 is located on the base 1, and the fixing mechanisms are distributed on the base 1 at intervals and surround the outside of the workpiece 13, so that the fixing mechanisms can fix the workpiece 13 from different directions.

[0030] Each fixing mechanism includes two fixing plates 2, a positioning rod 3, a push rod 4, a moving plate 5, a support tube 8, a first clamping plate 9, a moving rod 10, a pressure rod 11 and a second clamping plate 12;

[0031] The two fixed plates 2 are fixedly connected to the base 1, the positioning rod 3 is fixedly connected between the two fixed plates 2, a sliding hole is opened on the side wall of the movable plate 5, the positioning rod 3 passes through the sliding hole, a slide plate 501 is fixedly connected to the bottom of the movable plate 5, a rib is fixedly connected between the slide plate 501 and the movable plate 5, the slide plate 501 is slidably connected to the base 1, one end of the push rod 4 is fixedly connected to one side of the outer fixed plate 2, and the other end is fixedly connected to the movable plate 5. The push rod 4 is an electric push rod, so that the push rod 4 can be driven by electricity to work, so that the movable plate 5 can move outside the positioning rod 3.

[0032] The support tube 8 is arranged at an angle, and a support rod 6 is provided at the lower part. A latch 7 is provided on the support tube 8, and a plurality of sockets 601 are provided on the support rod 6 at intervals. By inserting the latch 7 into different sockets 601, the relative positions of the support tube 8 and the support rod 6 can be changed, so that the height of the first clamping plate 9 is changed, so as to adapt to workpieces 13 of different heights. The lower end of the support rod 6 is fixedly connected with a support column 602, and the support column 602 is Y-shaped. The two ends of the Y-shape of the support column 602 are respectively fixedly connected to the movable plate 5 and the slide plate 501, and the movable plate 5 can push the support rod 6 and the support tube 8 to move as a whole.

[0033] The other end of the support tube 8 is fixedly connected to the pressure rod 11, and one side of the first clamping plate 9 is fixedly connected to an ear plate 902, and a strip-shaped opening is opened on the ear plate 902, and the pressure rod 11 passes through the strip-shaped opening, and the pressure rod 11 can slide horizontally in the strip-shaped opening, so that the support tube 8 pushes the pressure rod 11 to move horizontally, thereby squeezing the first clamping plate 9 to make it fit the side wall of the workpiece 13, and the moving rod 10 is fixedly connected to the bottom of the second clamping plate 12, and a fixed sleeve 901 is provided on one side of the first clamping plate 9, and the moving rod 10 slides vertically in the fixed sleeve 901, and the side where the moving rod 10 and the pressure rod 11 are close to each other is A flat groove 1001 is provided, and anti-slip grooves are provided on the flat groove 1001. When the support tube 8 pushes the pressure rod 11 to move horizontally, the moving rod 10 and the flat grooves 1001 on the pressure rod 11 will fit together. At this time, the pressure rod 11 is pressed on the moving rod 10, thereby pushing the first clamping plate 9 as a whole to fit the side of the workpiece 13, and at the same time fixing the moving rod 10. At this time, the second clamping plate 12 fits the upper surface of the workpiece 13, and thus cooperates with the first clamping plate 9 to fix the side and upper surface of the workpiece 13, effectively preventing the workpiece 13 from being offset during processing.

[0034] The working principle of the anti-deviating precision machine tool processing positioning device is as follows: when in use, the workpiece 13 is first placed between the fixing mechanisms, and then the push rod 4 is driven by electricity to make the movable plate 5 move toward the workpiece 13 outside the positioning rod 3, and the movable plate 5 drives the support rod 6 to move, so that the support tube 8 is close to the workpiece 13, and the support tube 8 drives the first clamping plate 9 to be close to the side wall of the workpiece 3. At this time, the second clamping plate 12 is pulled upward to be on the upper surface of the workpiece 13, and then the support tube 8 is continued to be pushed by the push rod 4, and the support tube 8 drives the pressure rod 11 to move horizontally inside the strip-shaped opening of the ear plate 902 until the moving rod 10 and the flat groove 1001 on the pressure rod 11 fit each other. At this time, the pressure rod 11 generates a resisting force on the moving rod 10, which can, on the one hand, fit and fix the first clamping plate 9 to the side of the workpiece 13, and on the other hand, fix the moving rod 10, that is, the second clamping plate 12 on the upper surface of the workpiece 13 is fixed, so that the workpiece 13 is positioned and fixed from all directions to prevent the workpiece 13 from deviating;

[0035] For workpieces 13 of different heights, pulling out the pin 7 allows the support tube 8 to slide up and down on the outside of the support rod 6, thereby changing the positions of the first clamping plate 9 and the second clamping plate 12 to adapt to workpieces 13 of different heights. After adjusting the positions of the first clamping plate 9 and the second clamping plate 12, the pin 7 can be inserted into the corresponding socket 601 to fix the support tube 8 and the support rod 6.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
