[0025] The specific embodiments of the utility model are described in detail in combination with the drawings.

[0026] As Figures 1-9 shown, the utility model is a grinder for the inner hole of a spindle.

[0027] The grinding device for the inner hole of the spindle rod comprises a frame 1 and a spindle rod 6. One side of the frame 1 is provided with a square tube 1-1 extending outward, which is arranged on the lower plane of the frame 1. The square tube 1-1 is provided with symmetrically distributed first supporting frames 2 and second supporting frames 3 on both sides. The spindle rod 6 is placed on the second supporting frames 3. The first supporting frames 2 and the second supporting frames 3 are arranged at intervals, and the second supporting frames 3 are fixed by the second fixed shafts 12 penetrating through the square tube 1-1. The height of the first supporting frames 2 is less than that of the second supporting frames 3. The first supporting frames 2 are lifted by the driving mechanism 4 to move the spindle rod 6 forward. The second supporting frames 3 are provided with the grinding machine 5 driven by power to grind the inner hole. The first supporting frames 2 and the second supporting frames 3 are provided with grinding stations at the front ends, and the spindle rod 6 is limited by the left and right supporting frames 10. After grinding, the spindle rod 6 is pushed up by the driving top block 11 and pushed out forward by the driving push block 7. The push block 7 and the cylinder 44 are fixed on the upper plane of the frame 1 by the gasket 15. The cylinder 44 on the side of the grinding machine 5 is fixed on the upper plane of the frame 1 by the fixed plate 16.

[0028] Further, the first supporting frames 2 and the second supporting frames 3 are respectively provided with a plurality of sawteeth for positioning the spindle rod 6. The first supporting frames 2 and the second supporting frames 3 are sequentially connected by the sawteeth.

[0029] Further, the driving mechanism 4 comprises upper and lower clamping blocks 41. The lower clamping block 41 is arranged on the square tube 1-1. The first fixed shafts 43 are located between the clamping blocks 41 and extend out of the clamping blocks 41. The fixed blocks 42 are arranged on both sides of the first supporting frames 2 and have a cylindrical structure. The lower clamping block 41 is driven by the cylinder 44. The cylinder 44 is fixed by the angle steel 45 arranged below the square tube 1-1. When the cylinder 44 rises, the clamping blocks 41, the fixed blocks 42, the first fixed shafts 43 and the first supporting frames 2 simultaneously rise. After rising, the height of the first supporting frames 2 is higher than that of the second supporting frames 3, and the spindle rod 6 is moved to the position of the previous sawtooth.

[0030] Further, the front sides of the two supporting frames 10 are provided with inclined guide blocks 8 having a triangular cross section. The guide blocks 8 are fixed on the upper plane of the frame 1.

[0031] Further, the power is the cylinder 44.

[0032] Furthermore, the support 10 is provided with a V-shaped block 101 and a first waist-shaped groove 102, and the top block 11 is provided with a concave arc-shaped groove 111 and a second waist-shaped groove 112. During grinding, both ends of the spindle 6 are placed on the V-shaped block 101, and when pushed upwards, the spindle is located on the two arc-shaped grooves 111. The support 10 is fixed to the rear side of the guide block 8. The positions of the first waist-shaped groove 102 and the second waist-shaped groove 112 can be adjusted as needed. The cylinder 44 on the top block 11 is fixed by a connecting angle iron 14 fixed to the lower plane of the frame 1, and a connecting block 9 is provided above the cylinder 44, with the top block 11 located on both sides of the connecting block 9.

[0033] Furthermore, fixing blocks 42 are respectively provided on both sides of the second fixed shaft 12, located on the inner and outer sides of the second support frame 3, and the second support frame 3 is fixed by the fixing blocks 42 on both sides.

[0034] Furthermore, the second support frame 3 is provided with baffles 13 on both sides, the baffles 13 are fixed on the second support frame 3, and the baffles 13 are inclined outward in the upper direction.

[0035] Furthermore, each side of the upper plane of the frame 1 is provided with an upwardly extending stop 1-2.

[0036] When the grinding device for the inner hole of this spindle is in use, a spindle 6 is placed on each tooth of the second support frame 3. The drive mechanism 4 drives the first support frame 2 to rise, moving the spindle forward one position. At the grinding position, the cylinder 44 extends, and the grinding strip on the grinding machine 5 grinds the inner hole. After grinding is completed, the cylinder below the spindle moves upward, and the top block 11 pushes the spindle upward. Then, the cylinder 44 drives the push block 7 to move forward, pushing the spindle out. The spindle falls from the guide block 8 onto the upper plane of the frame 1. This cycle is repeated to grind the inner hole.

[0037] The above are preferred embodiments of the present utility model and do not limit the scope of protection of the present utility model. Any modifications and improvements made by those skilled in the art based on the design concept of the present utility model should be considered within the scope of protection of the present utility model.
