[0027] The automatic clamping assembly includes two groups of slide grooves symmetrically opened on the bracket, the slide grooves are slidably connected with sliders 101 inside, the two groups of sliders 101 are symmetrically fixedly connected with slide rods 102, and the slide rods 102 are slidably connected with the connecting block 4, the bottom of one side of the slider 101 is fixedly connected with an inverted T-shaped pressing piece 103, the top side of the cutting table 1 is symmetrically fixedly connected with a vertical rod 104, the outside of the vertical rod 104 is slidably connected with a sliding member, the outside of the sliding member is fixedly connected with a fixed block 105, and the fixed block 105 is in contact with the bottom of the pressing piece 103, and the outside of the vertical rod 104 is provided with a spring 106, the cutting table A stop bar 107 is fixedly connected to one side of the top of the cutting table 1, and a movable plate 108 is movably connected to the other side of the top of the cutting table 1. A connecting rod 109 is hinged between the movable plate 108 and the fixed block 105 through a hinge. A clamping plate 110 is arranged on one side of the movable plate 108, and a guide block is symmetrically fixedly connected to the bottom of the movable plate 108. Guide grooves are symmetrically provided on the top of the cutting table 1 and are slidably connected to the guide blocks, which can play a certain guiding role in the horizontal movement of the movable plate 108. An anti-slip pad is arranged on the outside of the clamping plate 110, which can increase the friction between the clamping plate 110 and the precision workpiece to prevent the precision workpiece from slipping during cutting.

[0028] The automatic clamping assembly also includes:

[0029] Two groups of cross bars 111 are symmetrically fixedly connected to one side of the clamping plate 110 and the cross bars 111 are slidably connected to the movable plate 108 . The outer part of the cross bars 111 is sleeved with a spring three 112 .

[0030] The connecting plate is symmetrically slidably connected with movable rods 201, the bottoms of the two groups of movable rods 201 are fixedly connected with the same positioning bar 202, the outer sleeve of the movable rod 201 is provided with a spring 203, one side of the positioning bar 202 is provided with an indicator plate 204, the top of the cutting table 1 is fixedly connected with a scale plate 205, and the blocking bar 107 is vertically connected to the zero scale line of the scale plate 205.

[0031] The implementation principle of a cutting device for precision parts processing in the embodiment of the present application is as follows: first, the precision workpiece is placed on the top of the cutting table 1 and one side of it is leaned on the stop bar 107, and then the cylinder 3 is started. In the process of pushing the cutting knife 5 vertically downward to cut the precision workpiece by the cylinder 3, the slider 101 and the slide bar 102 will move downward along with the push, so that the pressing piece 103 can be pushed downward, thereby pushing the fixed block 105 to slide on the outside of the vertical rod 104 and compress the spring 106. By utilizing the hinged effect between the fixed block 105 and the movable plate 108 and the connecting rod 109, and the sliding cooperation between the guide block and the guide groove, the movable plate 108 can be pushed to approach the precision workpiece, thereby driving the clamping plate 110 to approach the precision workpiece to clamp it. When the clamping plate 110 first contacts the precision workpiece, the movable plate 108 will slide on the outside of the cross bar 111 and compress the spring 3 112, thereby playing a role. A certain buffering effect is provided so that the cutting knife 5 can continue to move downward. During the vertical downward movement of the cutting knife 5, the positioning bar 202 can also be driven to move downward together. When the positioning bar 202 contacts the surface of the precision workpiece, the value indicated on the scale plate 205 at the bottom of the indicator plate 204 can be used to intuitively judge whether the actual cutting length is consistent with the required cutting length, thereby ensuring the accuracy of cutting the precision workpiece. When the indicated value is inconsistent with the value of the required cutting length, the electric slide 2 is controlled to move horizontally on the track so that the left and right positions can be adjusted. Then the motor is started, and the motor drives the cutting knife 5 to rotate so that the precision workpiece can be cut. The cutting knife 5 is pushed back and forth by the electric push rod 6 so that the precision workpiece can be completely cut. Finally, the cylinder 3 is controlled to drive the cutting knife 5 to reset. At this time, the positioning bar 202 and the clamping plate 110 will also reset together, and then the precision workpiece can be removed. Example

[0032] Based on Example 1, this embodiment is further improved in that: the indicator plate 204 is connected to the positioning bar 202 by limiting sliding, the top of the indicator plate 204 is rotatably connected to a screw rod 206, the positioning bar 202 is fixedly connected to a fixing seat, and the fixing seat and the screw rod 206 are threadedly connected. By rotating the screw rod 206 and cooperating with the limiting sliding connection between the indicator plate 204 and the positioning bar 202, the indicator plate 204 can be driven to move vertically, so that the position of the indicator plate 204 can be adjusted according to the thickness of the precision workpiece, thereby ensuring the clarity of the numerical indication on the scale plate 205.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
