[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1 The present invention provides a quick-change fixture for milling grooves in shaft parts, comprising: a base 1, a column 2 fixed on the upper surface of the base 1, a movable module 3 installed on one side of the column 2, a machining head 4 installed on the lower surface of the movable module 3, a machining platform 5 installed on the upper surface of the base 1, a clamping device 6 provided on the upper surface of the machining platform 5, and a cleaning device 7 provided on the side of the machining platform 5.

[0033] In the embodiments of this utility model, please refer to Figure 2 , Figure 3 and Figure 4The clamping device 6 includes a mounting plate 601. Several limiting holes 602 are formed on one side of the mounting plate 601. A turntable 603 is fixedly connected to one side of the mounting plate 601. Several sliding holes 604 are formed on one side of the turntable 603. Sliding rods 605 are slidably connected inside both the limiting holes 602 and the sliding holes 604. A clamping block 606 is fixedly connected to one side of the sliding rod 605. A motor 607 is fixedly connected to the upper surface of the processing platform 5. The output end of the motor 607 is fixedly connected to one side of the turntable 603. By setting the clamping device 6 on the upper surface of the processing platform 5, shaft-type parts can be quickly clamped, thereby facilitating the processing of shaft-type parts and improving the processing efficiency of the machine tool. An anti-slip pad 608 is fixed to one side of the clamping block 606. Several anti-slip patterns are evenly formed on one side of the anti-slip pad 608. The design enhances the friction between the clamping block 606 and the surface of the shaft parts, improving the clamping efficiency of the clamping block 606 when facilitating the clamping of shaft parts. Two sliding grooves 609 are formed on the inner wall of the limiting hole 602. A limiting rod 610 is slidably connected to the inner wall of the sliding groove 609, and the arc surface of the limiting rod 610 is fixedly connected to the arc surface of the slide rod 605. The cooperation between the sliding groove 609 and the limiting rod 610 facilitates the movement of the slide rod 605. A protective cover 611 is fixedly connected to the upper surface of the processing platform 5, enclosing the motor 607. Several heat dissipation holes 612 are formed on the side of the protective cover 611. The protective cover 611 protects the motor 607, preventing debris from scattering onto the motor 607 during the processing of shaft parts and affecting its operation.

[0034] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The cleaning device 7 includes two slots 71 located on both sides of the processing platform 5. A sliding component 72 slides along the inner wall of each slot 71, and a cleaning brush 73 is fixed to one side of each sliding component 72. The cleaning device 7, located on the side of the processing platform 5, cleans the upper surface of the platform 5, preventing debris from machining shaft parts from accumulating on the upper surface and minimizing its impact on shaft part machining. A sliding rod 74 slides along one side of the sliding rod 72. Both ends of the sliding rod 74 are fixedly connected to the inner wall of one of the slots 71. A spring 75 is fitted onto the arc surface of the sliding rod 74, and both ends of the spring 75 are fixedly connected to the inner wall of one of the slots 71 and one side of the sliding rod 72, respectively. The spring 75's spring-back effect after stretching allows the sliding rod 72 to be pulled back to its original position after movement. The movable frame 72 has a mounting groove 77 on one side, and a roller 78 is rotatably connected to the inner wall of the mounting groove 77. The inner wall of the other groove 71 has a moving groove 76, and the inner wall of the moving groove 76 fits against the arc surface of the roller 78. By using the cooperation of the moving groove 76 and the roller 78, the movable frame 72 can be moved easily.

[0035] The working principle of the quick-change fixture for milling grooves in shaft parts provided by this utility model is as follows: When milling grooves in shaft parts, if the clamping device 6 is needed to quickly clamp the shaft parts, first place one end of the shaft part between several clamping blocks 606, then start the motor 607. The rotation of the motor 607 drives the turntable 603 to rotate. The rotation of the turntable 603 drives the slide rod 605 to approach the shaft part along the slide hole 604 and the limiting hole 602. At this time, the clamping blocks 606 increase the friction with the shaft part with the help of the anti-slip pad 608, which facilitates the clamping of the shaft part. After the shaft part is processed, the rotation of the motor 607 drives the slide rod 605 to move along the limiting hole 602 and the slide hole 604 to release the clamping blocks 606 from the shaft part. After the clamping blocks 606 release the shaft part, the shaft part is taken out, and finally the motor 607 is turned off.

[0036] When the shaft parts are finished, there is too much waste on the surface of the machining platform 5. In order to reduce the impact of the waste on the next shaft machining, when the cleaning device 7 is needed, first pull the moving frame 72 along the groove 71 to drive the cleaning brush 73 to remove the waste from the upper surface of the machining platform 5. At this time, the moving frame 72 can be moved easily by the cooperation of the moving groove 76 and the roller 78. After the waste on the upper surface of the machining platform 5 is cleaned, the moving frame 72 is released, and the stretched spring 75 contracts to drive the moving frame 72 back to its original position.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
