[0027] More specifically, the distance between the left and right loading boxes 3 is adjusted by the distance adjusting mechanism 8, and then the distance between the long bevel supporting assembly 4, the short bevel supporting assembly 5, and the movable cutting supporting assembly 6 which are symmetrically distributed on the inner wall surface of the loading box 3 are adjusted, so that the long bevel supporting assembly 4, the short bevel supporting assembly 5, and the movable cutting supporting assembly 6 which are symmetrically distributed on the left and right can reliably support shaft parts of different diameters, and the position of the movable cutting supporting assembly 6 in the loading box 3 is adjusted by sliding, and the movable cutting supporting assembly 6 is fixed at a specified position by the positioning assembly 7, so that the movable cutting supporting assembly 6 can assist in positioning the cutting point while supporting the shaft parts, so as to meet the requirements of cutting the shaft parts at different positions, and then the shaft parts can be reliably fixed by pressing down the top squeezing fixing assembly 9, so as to adapt to the clamping requirements of shaft parts of more specifications.

[0028] The long bevel supporting assembly 4 includes a first supporting block 401 and a long bevel block 402.

[0029] Specifically, the first support block 401 and the long bevel block 402 are relatively long, and play a major supporting role for the shaft parts as a whole. By setting the second support block 501 and the short bevel block 502 on the rear side, the tail of the shaft parts can be positioned to prevent the tail of the shaft parts from vibrating during processing and affecting the processing effect.

[0030] The movable cutting support assembly 6 includes a movable slider 601, which is slidably installed on the inner wall surface of the loading box 3. A third support block 602 is fixedly installed on the top surface of the movable slider 601. A cutting bevel block 603 is fixedly installed on the top surface of the third support block 602. A cutting groove 604 is penetrated through the top of the cutting bevel block 603 and the third support block 602. The inclined surfaces of the long bevel block 402, the short bevel block 502 and the cutting bevel block 603 are coated with a rubber layer 10.

[0031] Specifically, by sliding and adjusting the position of the movable slider 601 on the inner wall surface of the loading box 3, the third support block 602 and the cutting bevel block 603 are moved, and then the cutting groove 604 for the blade to feed is moved, and the distance between the cutting groove 604 and the back of the second support block 501 is adjusted, so that the cutting position for the shaft parts can be adjusted.

[0032] The positioning assembly 7 includes a threaded hole 701, a bolt 702 and a scale line 703. The threaded hole 701 is opened on the left and right side walls of the loading box 3.

The bolt 702 is threadedly installed on the inner wall surface of the threaded hole 701 and threadedly inserted on the surface of the movable slider 601. The scale line 703 is engraved on the top surface of the loading box 3.

[0033] Specifically, the scale line 703 is used to assist the operator in confirming the distance between the cutting groove 604 and the back of the second support block 501 , so that the operator can select the threaded hole 701 at a suitable position as needed, and rotate and insert the bolt 702 therein to fix the movable slider 601 , thereby achieving the positioning of the cutting groove 604 .

[0034] The distance adjustment mechanism 8 includes a main slide groove 801 and an auxiliary slide groove 802. The main slide groove 801 and the auxiliary slide groove 802 are both opened on the top surface of the base plate 1 and are arranged front and back. The number of the main slide groove 801 and the auxiliary slide groove 802 are both two and are symmetrically arranged left and right. The inner wall surfaces of the main slide groove 801 and the auxiliary slide groove 802 are both slidably installed with a transverse slider 803. A double-headed threaded rod 804 is rotatably installed on the inner wall surfaces of the two main slide grooves 801. The double-headed threaded rod 804 is arranged to penetrate the side of the base plate 1. A knob 805 is fixedly installed on the surface of one end of the double-headed threaded rod 804 located outside the base plate 1. The transverse slider 803 located in the main slide groove 801 is symmetrically threaded on the surface of the double-headed threaded rod 804. The top surfaces of the two transverse sliders 803 arranged front and back are fixedly connected to the bottom surface of the loading box 3.

[0035] Specifically, rotating the knob 805 drives the double-headed threaded rod 804 to rotate, so that the two transverse sliders 803 that are symmetrically threadedly installed on the surface of the double-headed threaded rod 804 and slidably installed on the inner wall surface of the main slide 801 move toward or away from each other synchronously, thereby driving the left and right relatively arranged loading boxes 3 fixedly installed on the top surface of the transverse slider 803 to move toward or away from each other synchronously, thereby adjusting the distance between the two loading boxes 3, and finally adjusting the distance between the long bevel support assembly 4, the short bevel support assembly 5, and the movable cutting support assembly 6 on the left and right sides, so that they can reliably support shaft parts of different specifications. The transverse slider 803 in the secondary slide 802 cooperates with the secondary slide 802 to enhance the stability of the loading box 3 when moving.

[0036] The top extrusion fixing component 9 includes a hydraulic push rod 901, which is fixedly installed on the bottom surface of the base plate 1. The telescopic end of the hydraulic push rod 901 is fixedly installed with a base plate 902. Insertion rods 903 are fixedly installed at the four corners of the top surface of the base plate 902. The insertion rods 903 are slidably inserted into the surface of the base plate 1. Long extrusion plates 904 are fixedly installed on the top surfaces of the two front insertion rods 903, and short extrusion plates 905 are fixedly installed on the top surfaces of the two rear insertion rods 903. The long extrusion plate 904 is arranged directly above the long inclined support component 4, and the short extrusion plate 905 is arranged directly above the short inclined support component 5. The middle part of the bottom surface of the long extrusion plate 904 and the short extrusion plate 905 is provided with an arc groove.

[0037] Specifically, the telescopic end of the hydraulic push rod 901 is extended and retracted to drive the bottom plate 902 to rise and fall, so that the insertion rod 903 fixedly installed on the top surface of the bottom plate 902 and slidably inserted on the surface of the base plate 1 is raised and lowered, and finally drives the long extrusion plate 904 and the short extrusion plate 905 fixedly installed on the top surface of the insertion rod 903 to rise and fall, so that the long extrusion plate 904 cooperates with the long inclined support assembly 4 to extrude and fix the front part of the shaft part, and the short extrusion plate 905 cooperates with the short inclined support assembly 5 to extrude and fix the rear part of the shaft part.

[0038] In summary: the distance between the left and right loading boxes 3 is adjusted by the distance adjusting mechanism 8, and then the distance between the long bevel supporting assembly 4, the short bevel supporting assembly 5, and the movable cutting supporting assembly 6 which are symmetrically distributed on the inner wall surface of the loading box 3 are adjusted, so that the long bevel supporting assembly 4, the short bevel supporting assembly 5, and the movable cutting supporting assembly 6 which are symmetrically distributed on the left and right can reliably support shaft parts of different diameters, and then the shaft parts can be reliably fixed by pressing down the top squeezing fixing assembly 9, so that the clamping requirements of shaft parts of more diverse specifications can be met; the position of the movable cutting supporting assembly 6 in the loading box 3 is adjusted by sliding, and the movable cutting supporting assembly 6 is fixed at the specified position by the positioning assembly 7, so that the movable cutting supporting assembly 6 can assist in positioning the cutting point while supporting the shaft parts, so as to meet the requirements of cutting shaft parts at different positions.
