[0022] Please refer to Figures 1-5 As shown in the figure, a clamping support for machining an automotive half shaft includes a base 1; a receiving plate 2 is fixedly connected to the top of the base 1; a pair of balance rods 3 are slidably connected to the side wall of the receiving plate 2; one end of the balance rod 3 is fixedly connected to a push plate 4; a threaded rod 5 is threadedly connected to the side wall of the receiving plate 2; one end of the threaded rod 5 is rotatably connected to a rotating sleeve 6; the side wall of the rotating sleeve 6 is fixedly connected to the push plate 4 through a fixed connection frame; a pair of T-shaped blocks are fixedly connected to the bottom of the push plate 4; the T-shaped blocks are slidably connected to the base 1 through T-shaped grooves 9; a fixing plate 10 is fixedly connected to the top of the base 1; a first abutting disc 11 is rotatably connected to the side wall of the fixing plate 10; a second abutting disc 12 is provided on the side wall of the push plate 4 through a clamping member; during operation, by the operator rotating the threaded rod 5, the threaded rod 5 will perform a threaded rotation with the receiving plate 2, so that the threaded rod 5 will drive the push plate 4 to slide on the base 1, and then the push plate 4 drives the first abutting disc 11 to move, so that the automotive half shaft can be fixedly clamped between the first abutting disc 11 and the second abutting disc 12. Under the action of the clamping member, the automotive half shaft can be rotated and adjusted under the condition of fixed clamping, which simplifies the fixing method for the operator when grinding the automotive half shaft, reduces the time consumption of the operator in fixing and rotating the clamping support, and improves the grinding efficiency of the automotive half shaft.

[0023] The clamping member includes a slide rod 14; the second abutting disc 12 is rotatably connected to the push plate 4; a plurality of groups of clamping grooves 13 are provided on the side wall of the second abutting disc 12; the clamping grooves 13 are arc-shaped; a circular groove is provided on the side wall of the push plate 4; the slide rod 14 is slidably connected to the groove wall of the circular groove; one end of the slide rod 14 is provided with an arc-shaped surface; the slide rod 14 is matched with the clamping groove 13; a square groove is provided on the side wall of the push plate 4; the square groove is communicated with the circular groove; a square block 15 is slidably connected to the groove wall of the square groove; the square block 15 is fixedly connected to the slide rod 14; inclined surfaces are provided on both side walls of the square block 15; a pair of receiving blocks 16 are provided on the side wall of the push plate 4; a bidirectional threaded rod 17 is rotatably connected between the pair of receiving blocks 16, and one end of the bidirectional threaded rod 17 penetrates through the receiving block 16; a pair of symmetrically distributed pressing blocks 18 are threadedly connected to the outer wall of the bidirectional threaded rod 17; the pressing blocks 18 are matched with the square block 15; during operation, by the operator rotating the bidirectional threaded rod 17, the bidirectional threaded rod 17 will simultaneously drive the pair of pressing blocks 18 to move in opposite directions to each other, and then the pair of pressing blocks 18 will press the inclined surfaces of the square block 15, and then the square block 15 slides into the direction groove under the extrusion force to drive the slide rod 14 to move, and then one end of the slide rod 14 will enter the clamping groove 13 to realize the function of clamping the rotation of the second abutting disc 12.

[0024] A connecting block 19 is fixedly connected to the side wall of the square block 15; a receiving rod 20 is slidably connected to the side wall of the connecting block 19; the receiving rod 20 is fixedly connected to the side wall of the push plate 4; a spring is fixedly connected between the connecting block 19 and the push plate 4; during operation, when the staff needs to rotate and adjust the automotive half shaft when it is clamped, the bidirectional threaded rod 17 is rotated, so that a pair of extrusion blocks 18 release the extrusion on the square block 15. Since the clamping groove 13 is arc-shaped, when the staff directly rotates the automotive half shaft with a certain force, one end of the sliding rod 14 will automatically break away from the groove after being squeezed in the clamping groove 13. After the second abutting disc 12 rotates with the automotive half shaft, one of the multiple groups of clamping grooves 13 will correspond to the sliding rod 14. At this time, the acting force of the spring will make the sliding rod 14 slide in the sliding groove and enter the clamping groove 13, achieving the effect of auxiliary positioning. Such a simplified operation can reduce the number of times of repetitive labor of the staff and reduce their labor intensity.

[0025] First circular grooves 21 are provided on the side walls of both the first abutting disc 11 and the second abutting disc 12; multiple groups of first arc grooves 22 are provided on the groove walls of the first circular grooves 21; a second circular groove 23 is provided at the bottom of the first circular grooves 21; an annular block 24 is rotatably connected to the groove wall of the second circular groove 23; multiple groups of second arc grooves 25 are provided on the inner circular wall of the annular block 24; a thimble 26 is placed on the inner circular wall of the annular block 24; multiple groups of arc-shaped blocks 27 are fixedly connected to the outer circular wall of the thimble 26; the arc-shaped blocks 27 are matched with the first arc grooves 22 and the second arc grooves 25; during operation, through the arc-shaped blocks 27 on the thimble 26, when the thimble 26 is inserted into the first circular groove 21, the arc-shaped blocks 27 on the thimble 26 will enter the first arc grooves 22. Then when the staff continues to push the thimble 26 forward, the thimble 26 will enter the annular block 24 in the second circular groove 23. At this time, the arc-shaped blocks 27 will also be inserted into the second arc grooves 25. Then the staff rotates the thimble 26, and the annular block 24 will also rotate in the first circular groove 21, causing the arc-shaped blocks 27 to rotate with the annular block 24, making the arc-shaped blocks 27 misaligned with the first arc grooves 22. In this way, the thimble 26 will be limited on the second abutting disc 12, facilitating the staff to replace thimbles 26 of different sizes on the second abutting disc 12, so as to cooperate with the positioning of different types of automotive half shafts on the device.

[0026] A sliding groove is provided at the bottom of the base 1; a pair of the T-shaped grooves 9 communicate with the sliding groove; a collecting box 28 is slidably connected to the two side groove walls of the sliding groove; during operation, due to the communication between the sliding groove and the T-shaped grooves 9, debris will be generated when the staff grinds the automotive half shaft. When the debris enters the T-shaped grooves 9, the debris will enter the collecting box 28 from the T-shaped grooves 9, facilitating the collection and treatment of the debris in the T-shaped grooves 9.

[0027] One end of each of the threaded rod 5 and the double-threaded rod 17 is fixedly connected with a rotating handle 29; during operation, through the rotating handles 29 on the threaded rod 5 and the double-threaded rod 17, the staff can replaceably control the threaded rod 5 and the double-threaded rod 17.

[0028] Working principle: By rotating the threaded rod 5 by the staff, the threaded rod 5 will perform threaded rotation with the receiving plate 2. Thus, the threaded rod 5 will drive the push plate 4 to slide on the base 1. Subsequently, the push plate 4 drives the first abutting disc 11 to move, so that the automotive half shaft can be fixedly clamped between the first abutting disc 11 and the second abutting disc 12. Under the action of the positioning member, the automotive half shaft can be rotationally adjusted while being fixedly clamped, making it easier for the staff to fix it when grinding the automotive half shaft, reducing the time consumption of the staff in fixing and rotating the clamping support, and improving the grinding efficiency of the automotive half shaft. By rotating the bidirectional threaded rod 17 by the staff, the bidirectional threaded rod 17 will simultaneously drive a pair of extrusion blocks 18 to move towards each other. Subsequently, the pair of extrusion blocks 18 will extrude the inclined surface of the square block 15. Then, the square block 15 slides into the direction groove under the extrusion force, driving the slide bar 14 to move. Subsequently, one end of the slide bar 14 will enter the positioning groove 13, achieving the function of positioning the rotation of the second abutting disc 12. When the staff needs to rotate and adjust the automotive half shaft during clamping, by rotating the bidirectional threaded rod 17 to release the extrusion of the pair of extrusion blocks 18 on the square block 15, since the positioning groove 13 is arc-shaped, when the staff directly rotates the automotive half shaft with a certain force, one end of the slide bar 14 will be automatically squeezed out of the groove after being squeezed in the positioning groove 13. After the second abutting disc 12 rotates with the automotive half shaft, one of the multiple positioning grooves 13 will correspond to the slide bar 14. At this time, the acting force of the spring will make the slide bar 14 slide in the chute and enter the positioning groove 13, achieving the effect of auxiliary positioning. Such a simplified operation can reduce the number of repetitive tasks of the staff and reduce their labor intensity. Through the arc-shaped block 27 on the ejector pin 26, when the ejector pin 26 is inserted into the first circular groove 21, the arc-shaped block 27 on the ejector pin 26 will enter the first arc-shaped groove 22. Then, when the staff continues to push the ejector pin 26, the ejector pin 26 will enter the annular block 24 in the second circular groove 23. At this time, the arc-shaped block 27 will also be inserted into the second arc-shaped groove 25. Then the staff rotates the ejector pin 26, and the annular block 24 will also rotate in the first circular groove 21, causing the arc-shaped block 27 to rotate with the annular block 24, making the arc-shaped block 27 misaligned with the first arc-shaped groove 22. In this way, the ejector pin 26 will be limited on the second abutting disc 12, facilitating the staff to replace ejector pins 26 of different sizes on the second abutting disc 12 to cooperate with the positioning of different types of automotive half shafts on the device. Through the chute being communicated with the T-shaped groove 9, debris will be generated when the staff grinds the automotive half shaft. When the debris enters the T-shaped groove 9, the debris will enter the collection box 28 from the T-shaped groove 9, facilitating the collection and treatment of the debris in the T-shaped groove 9. Through the rotating handles 29 on the threaded rod 5 and the bidirectional threaded rod 17, the staff can replaceably control the threaded rod 5 and the bidirectional threaded rod 17.
