[0042] The feeding mechanism 2 includes a frame 21 fixedly connected to the side of the platform 1. A housing 22 is fixedly installed on the top of the frame 21. A material trough 23 is fixedly installed inside the housing 22. Rectangular plates 25 are embedded and fixedly installed on the inner walls of both sides of the housing 22. A guide plate 27 is fixedly installed on the side of the two rectangular plates 25 that are close to each other. A horizontal plate 26 is fixedly installed on the housing 22.

Two upright plates 35 are fixedly mounted on the top of the top plate 34. A single-axis telescopic cylinder 36 is fixedly mounted on the bottom of the slide plate 32. The piston rod of the upright plate 35 slides through the slide plate 32 and is fixedly connected to the bottom of the top plate 34. A second single-axis telescopic cylinder 37 is fixedly mounted on the top of the slide plate 32. The end of the piston rod of the second single-axis telescopic cylinder 37 is fixedly connected to the slide plate 32.

[0045] The top of the upright plate 35 has two transfer slots 351 and two transfer slots 352. Both sides of the slide plate 32 are fixedly installed with accordion covers 38. The two accordion covers 38 are fixedly connected to the top of the slide plate 32 on the side that is far away from each other.

[0046] The clamping mechanism 4 includes a double-rail manual linear module 41 fixedly installed on the top of the frame 1. A movable plate 42 is fixedly installed on the slider of the double-rail manual linear module 41. A vertical plate 43 is fixedly installed on the top of the movable plate 42.

A vertical plate 2 53 and a vertical plate 3 54 are fixedly installed on the top of the movable plate 2 52. Two round shafts 2 55 are rotatably mounted through the vertical plate 2 53. A chuck 2 56 is fixedly installed at the end of the two round shafts 2 55 away from the vertical plate 3 54. A positioning rod 2 57 is clamped on the two chucks 2 56. A pulley 1 58 is fixedly installed at the end of the two round shafts 2 55 near the vertical plate 3 54. A motor 2 59 is fixedly mounted through the vertical plate 3 54. A pulley 2 510 is fixedly installed at the end of the output shaft of the motor 2 59. The same synchronous belt is sleeved on the pulley 2 510 and the two pulleys 1 58. The clamping mechanism 25 also includes a cover 2 511 fixed to the top of the platform 1.

[0048] Furthermore, the two positioning rods 48 are coaxial with the corresponding positioning rods 57. The ends of the positioning rods 48 and 57 that are close to each other are provided with conical grooves. With the cooperation of the two conical grooves, when the coaxial positioning rods 48 and 57 approach each other, the center shaft workpiece 10 to be clamped can be automatically centered, so that the center shaft workpiece 10 can automatically maintain coaxiality with the positioning rods 48 and 57 after being clamped.

[0049] Furthermore, the first moving plate 42 moves above the dual-rail manual linear module 41 via manual control, while the second moving plate 52 moves above the dual-rail electric linear module 51 via automated control.

[0050] When the second motor 59 is started, the two pulleys 58 can be driven to rotate synchronously in the same direction through the cooperation of the second pulley 510 and the timing belt. The two pulleys 58 then drive the two positioning rods 57 to rotate synchronously in the same direction through the corresponding round shaft 55 and the chuck 56.

[0051] The floating grinding mechanism 6 includes a gantry frame 61 fixedly installed on the top of the platform 1. An electric linear module 62 is fixedly installed on the side of the gantry frame 61 near the feeding mechanism 2. An electric linear module 63 is fixedly installed on the slider of the electric linear module 62. The electric linear modules 62 and 63 are arranged horizontally and vertically. A mounting plate 64 is fixedly installed on the slider of the electric linear module 63. Two round rods 65 and two elliptical frames 69 are fixedly installed on one side of the mounting plate 64. A swing block is rotatably mounted on each of the two round rods 65. 66. A motor 67 is fixedly installed on the swing block 66. A grinding wheel 68 is fixedly installed at the end of the output shaft of the motor 67. A pull rod 610 is fixedly installed on the side of the swing block 66 near the elliptical frame 69. The pull rod 610 slides through the elliptical frame 69. A return spring 611 is slidably sleeved on the pull rod 610. The bottom end of the return spring 611 is fixedly connected to the swing block 66. The top end of the return spring 611 is slidably connected to the elliptical frame 69. A round rod 65 is fixedly installed on the mounting plate 64. A chip removal pipe 9 with an opening facing the two grinding wheels 68 is installed on the gantry frame 61.

[0052] Furthermore, during the process of the grinding wheel 68 abutting against the central shaft workpiece 10 to be ground, the return spring 611 allows the swing block 66 to float up and down, preventing the grinding wheel 68 from directly contacting the central shaft workpiece 10 to be ground. This provides a certain degree of protection for both the grinding wheel 68 and the central shaft workpiece 10 to be ground. The return spring 611 also ensures that the grinding wheel 68 remains in close contact with the central shaft workpiece 10 during the grinding process. The chip removal pipe 9 is used to connect to an external fan. By creating a negative pressure state inside the chip removal pipe 9, the chips generated when the grinding wheel 68 grinds the central shaft workpiece 10 can be sucked away, reducing the accumulation of chips on the equipment or the occurrence of splashing.

[0053] A repair mechanism 7 is installed on the test stand 1. The repair mechanism 7 includes an electric linear module 3 71 fixedly installed on the top of the test stand 1. An electric linear module 4 72 is fixedly installed on the slider of the electric linear module 3 71. The electric linear module 3 71 and the electric linear module 4 72 are arranged horizontally and vertically. A diamond grinding head 73 is fixedly installed on the slider of the electric linear module 4 72.

[0054] Furthermore, the position of the diamond grinding head 73 is adjusted by electric linear module three 71 and electric linear module four 72, and the positions of the two grinding wheels 68 are adjusted in conjunction with electric linear module one 62 and electric linear module two 63. When the grinding wheel 68 wears out after grinding for a long time, the worn grinding wheel 68 can be repaired by grinding with the diamond grinding head 73, which has a higher hardness. During the grinding and repair process, motor three 67 needs to be started to drive the grinding wheel 68 to rotate.

[0055] The material storage mechanism 8 includes a second platform 83 fixedly installed on the side of the first platform away from the feeding mechanism 2, and a truss 81 fixedly installed on the top of the first platform. The top of the second platform 83 is provided with a material frame 84, and the top of the truss 81 is fixedly installed with two inclined guide bars 82.

[0056] In this embodiment: During use, the central shaft workpieces 10 are stacked parallel to each other in the material trough 23. Under the action of gravity, the central shaft workpieces 10 will move to one side of the guide plate 27, and part of the central shaft workpieces 10 will abut against the inclined side 271. The central shaft workpiece 10 located at the lowest point abuts against the sides of the two rotating discs 29. Then, the motor 211 is started to drive the rotating shaft 210 to rotate. The rotating shaft 210 then drives the two rotating discs 29 to rotate synchronously. When the rotating trough 291 rotates to the space between the inclined side 282 and the guide plate 27, the central shaft workpiece 10 at the lowest point will roll into the rotating trough 291 along the inclined side 282. As the rotating discs 29 continue to rotate, the central shaft workpieces 10 will be carried by the rotating discs 29. With synchronous rotation, the transfer disk 29 drives the central shaft workpiece 10 to rotate between the semi-circular groove 272 and the semi-circular protrusion 283 and then land on the second inclined side 281. Then, under the action of gravity, the central shaft workpiece 10 automatically falls out of the central transfer groove 291 and rolls along the second inclined side 281 to the first station 285 for temporary storage. Then, the double-axis telescopic cylinder 212 is controlled to drive the U-shaped plate 213 to move upward. The next central shaft workpiece 10 transferred to the second inclined side 281 by the two transfer disks 29 rolls down along the second inclined side 281 and is blocked by the U-shaped plate 213. Then, the central shaft workpiece 10 will land on the second station 286 for temporary storage. At this time, there is one central shaft workpiece 10 temporarily stored on the first station 285 and the second station 286 respectively.

[0057] Then, control the single-axis telescopic cylinder 36 and the single-axis telescopic cylinder 37 to extend and retract, so that the two upright plates 35 move below the two guide plates 28. Then, control the single-axis telescopic cylinder 36 to drive the two upright plates 35 to move upward through the top plate 34, so that the two transfer grooves 351 on the upright plates 35 respectively support the two central shaft workpieces 10 on the first station 285 and the second station 286, and support the two central shaft workpieces 10 to move in the opposite direction to separate from the guide plates 28. Then, the single-axis telescopic cylinder 37 drives the two central shaft workpieces 10 to move between the clamping mechanism 4 and the clamping mechanism 5, and control the single-axis telescopic cylinder 36 to drive the two upright plates 35 and the two central shaft workpieces 10 to move downward.

[0058] When the two central shaft workpieces 10, which have moved between clamping mechanism 1 4 and clamping mechanism 2 5, move down and become coaxial with the corresponding positioning rod 2 57 and chuck 1 47 respectively, the two single-axis telescopic cylinders 3 44 extend simultaneously and push the two positioning rods 1 48 to move towards the corresponding coaxial positioning rod 2 57. During this process, the two sets of coaxial positioning rods 2 57 and positioning rods 1 48 will clamp the two ends of the corresponding central shaft workpieces 10. Then, the single-axis telescopic cylinder 1 36 retracts and drives the two vertical plates 35 to move down and separate from the two central shaft workpieces 10. The motor 2 59 drives the two positioning rods 2 57 to rotate, so that the two clamped central shaft workpieces 10 to be ground can rotate.

[0059] Then, control the two grinding wheels 68 to move directly above the two central shaft workpieces 10 between the clamping mechanism 1 4 and the clamping mechanism 2 5 and to fit into the two central shaft workpieces 10. Then, the two rotating grinding wheels 68 rotate and move along the axis of the corresponding central shaft workpiece 10 and float up and down to complete the grinding of the central shaft workpiece 10.

[0060] After the two central shaft workpieces 10 between clamping mechanism 14 and clamping mechanism 25 are ground, the two vertical plates 35 will move back to below the two guide plates 28. Then, the single-axis telescopic cylinder 136 will be controlled to drive the two vertical plates 35 upward through the top plate 34, so that the two transfer grooves 251 on the vertical plate 35 will support the two central shaft workpieces 10 on station 1 285 and station 2 286 respectively. During this process, the two transfer grooves 352 on the vertical plate 35 will support the two central shaft workpieces 10 that have been ground between clamping mechanism 14 and clamping mechanism 25 respectively. At the same time, clamping mechanism 14 and clamping mechanism 25 will release the two ground central shaft workpieces 10, and the two ground central shaft workpieces 10 will fall into the two transfer grooves 352 on the vertical plate 35 for temporary storage.

[0061] Afterwards, when the two vertical plates 35 remove the two central shaft workpieces 10 to be ground from the feeding mechanism 2 and move them between the clamping mechanism 1 4 and the clamping mechanism 2 5 for clamping, the vertical plates 35 need to move the two central shaft workpieces 10 to be ground upwards to separate them from the guide plate 2 28. Then, the vertical plates 35 move the two central shaft workpieces 10 to be ground horizontally between the clamping mechanism 1 4 and the clamping mechanism 2 5. At this time, the two central shaft workpieces 10 after grinding are placed on the two transfer grooves 352 on the vertical plates 35. 10 moves above the two guide bars 82, and then the upright plate 35 drives the two center shaft workpieces 10 to be ground to move down and be coaxial with the corresponding positioning rod 1 48 and positioning rod 2 57. During the process of the upright plate 35 driving the two center shaft workpieces 10 to be ground to move down and be coaxial with the corresponding positioning rod 1 48 and positioning rod 2 57, the two center shaft workpieces 10 after being ground in the two transfer grooves 352 on the upright plate 35 will fall on the guide bars 82 and roll along the guide bars 82 into the material frame 84 for temporary storage.
