Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.

It should be noted that, the terms "above," "one end," "upper," and the like are used herein to indicate an orientation or a positional relationship based on the orientation or the positional relationship shown in the drawings, and are merely for convenience of description and simplification of the description, and similar expressions are merely for the purpose of illustration, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the utility model; furthermore, the terms "a," "an," "the two," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The damping device for mechanical grinding shown in fig. 1 comprises a mandrel 4, a steel ring 1, a left baffle plate 3, a right baffle plate 5, a sliding sleeve 6 and a nut 7 which are sequentially sleeved outside the mandrel.

The center hole is formed in the thimble end of the mandrel 4, the center hole can be propped by the thimble, the clamping end of the mandrel 4 is cylindrical, and the mandrel is convenient to fix to a grinding machine through a clamp of the grinding machine, so that rotation of the mandrel 4 is achieved.

The steel ring 1 is fixedly sleeved outside the thimble end, and the jackscrew 2 is radially inserted into the steel ring 1, so that a bolt which is parallel to the mandrel 4 in the axial direction can be fixed on one end of the thimble of the grinding machine, and the jackscrew 2 is vertically sleeved on the bolt, so that the rotation of one end of the thimble of the grinding machine can be realized, and the steel ring 1 and the thimble can be synchronously driven to rotate.

Wherein, the position on the mandrel 4 near the thimble end is provided with a first shoulder, namely a stepped shaft structure. The first shoulder limits the left baffle plate 3 movably sleeved outside the mandrel 4 to move towards the direction close to the thimble end, and the left baffle plate 3 is sleeved into the mandrel from the clamping end.

Wherein, a pair of opposite side surfaces of the right baffle 5 and the left baffle 3 are respectively provided with a shock absorption layer, and a grinding product movably sleeved on the mandrel 4 is arranged between the two shock absorption layers; preferably, the shock absorbing layer is rubber. The right baffle 5 and the left baffle 3 are of metal ring structures, and rubber is fixedly attached to the metal rings.

Wherein, be close to dabber 4 the clamping end be provided with the supporting screw thread of nut 7, sliding sleeve 6 pushes up the grinding product under the effect of nut 7.

It is easy to think that the diameter of the grinding product is larger than the outer diameters of the right baffle plate 5 and the left baffle plate 3, more grinding operation space is obtained, the grinding product is attached between the two shock absorption layers, and the vibration suffered by the grinding product is reduced; meanwhile, the position of the right baffle is fixed through the sliding sleeve and the nut instead of the position of the right baffle is fixed through one nut, and the fixing effect of the right baffle is better, because if the baffle 5 is vibrated by the transmission of a grinding product, the nut can vibrate, the locking effect is poor, and the sliding sleeve 6 weakens the vibration force of the nut 7; for longer grinding products, the grinding products can be pressed onto the threads, and the products vibrate to damage the threads for a long time; because the axial position of the nut 7 on one end length can be adjusted, the sliding sleeve can be applied to grinding products with different lengths.

Preferably, the grinding and shock absorbing device comprises a plurality of sliding sleeves 6 with different axial lengths, and the sliding sleeves 6 are alternatively sleeved outside the mandrel 4. Thus, grinding products with different lengths are further used, and the positions of the right baffle plate 5 are different due to the fact that the positions of the threads are fixed, but the lengths of the grinding products are different, so that the matched sliding sleeve 6 is selected to adjust the distance between the right baffle plate 5 and the nut 7.

While certain exemplary embodiments of the present utility model have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the utility model, which is defined by the appended claims.
