The invention discloses an anti-collision knife numerical control machine tool, comprising a machine tool body, an x-axis motor, an x-axis screw, a y-axis screw, a y-axis motor, a z-axis slide rail, a z-axis screw, a fixing frame and a fourth motor , shell, fixture, collection trolley and anti-collision tool device, the built-in milling cutter in the fixture accidentally hits the support plate downwards during the debugging process, and under the action of the spring force, the support plate slides down to provide buffering for the built-in milling cutter in the fixture , to prevent the built-in milling cutter of the fixture from directly hitting the built-in milling cutter of the fixture and cause the cutter to break and damage. After the debugging of the CNC program is completed, the fifth motor starts to rotate forward, so that the fourth screw rod moves upward, and the connection block at the top is attached to the limit. The bottom end face of the block is used to fix the top support plate. During the deep hole machining of the workpiece, the workpiece will sink under the action of the spring force, which will cause the spring to buffer the workpiece and cause workpiece accuracy errors. This device fixes the support plate to avoid The machining error of the workpiece is affected by the spring force during the machining process.

The hourglass worm processing machine tool comprises a machine tool body, wherein a spindle unit and a processing unit are arranged on the machine tool body; the spindle unit comprises a driving centre and a tailstock centre, which are used for ejecting and holding a hourglass worm to be processed; the processing unit is used for processing the tooth surface of the hourglass worm; the hourglass worm processing machine tool further comprises a detection unit and a control unit, so that on-line detection and correction processing are realized during the processing process of the tooth surface of the hourglass worm, and the problem of low processing precision of the tooth surface of the hourglass worm is solved basically.

The invention discloses a long-life blade surface treatment device, which includes a base, a workbench, a blade body, a fixing mechanism, a cooling mechanism and a recovery mechanism. The fixing mechanism is located at the bottom of the workbench, and the fixing mechanism includes an air pump. The output shaft of the air pump is fixedly connected with a connecting pipe, the top of the connecting pipe is fixedly connected with a cavity plate, and the inside of the workbench is provided with an air suction groove; through the designed air pump, connecting pipe, cavity plate and The air extraction groove can use the principle of air pressure difference to fix the blade body, and at the same time, through the first set of rods, connecting plates and guide rods, the top of the partial air extraction groove can be covered, so that blade bodies of different sizes can be fixed. It is fixed, and at the same time, it is convenient to limit the position of the connecting plate by providing a clamping groove, a first fixed block, a fixed plate and a clamping column, thereby increasing the stability of the device and solving the problem of a single structure of the fixing method and a cumbersome fixing process .

The invention discloses a processing method and system for cracking pecan shells. The system includes cracking equipment and a main control device; wherein, the cracking equipment includes: a feeding hopper, cracking rollers, a sensing device and a pneumatic cracking device. shell hammer; the main control device transmits the hickory nuts fed into the feeding hopper to the cracking rollers, and controls the vertical reciprocating movement of the pneumatic cracking hammer to crack the hickory nuts; wherein, the main control device and the pneumatic The cracking hammer is connected; the deformation amount of the hickory nut detected by the sensing device is obtained; wherein, the sensing device is arranged on the pneumatic cracking hammer, and the sensing device is connected with the main control device; the main control device is in the When the deformation amount is greater than or equal to the preset compression amount, it is determined that the pneumatic cracking hammer has completed the hickory cracking process, and the pneumatic cracking hammer is controlled to reset to the initial state, thereby solving the problem of processing the hickory cracking shell. The problem of low machining accuracy in the process.

The invention discloses a multi-axis processing system, a processing method, a device, and a computer-readable storage medium, wherein the multi-axis processing system includes a plurality of processing axes, and each processing axis corresponds to a processing area, and the method includes the following steps: obtaining The actual coordinates of at least two positioning points on the board to be processed in at least one processing area, so as to obtain the actual coordinates of multiple positioning points; obtain the coordinate difference between the actual coordinates and theoretical coordinates of each positioning point in the multiple positioning points Values ​​to obtain multiple processing compensation values; obtain the average value of multiple processing compensation values ​​as the processing compensation values ​​of multiple processing axes; perform compensation processing on the plate to be processed according to the processing compensation values ​​of multiple processing axes. This method can not only improve the problem of low processing accuracy caused by the large difference between the expansion and contraction coefficient and the actual value, but also solve the problem of low processing accuracy caused by large installation errors, and improve the processing accuracy and quality.
