DETAILED DESCRIPTION

In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

It should be noted that the terms "above", "one end", "upper", etc. used in this article to indicate the orientation or position relationship is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Similar expressions are only for the purpose of illustration, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

As shown in FIG. 1 , a vibration reduction device for mechanical grinding includes a mandrel 4 , a steel ring 1 sequentially sleeved on the outside of the mandrel, a left baffle 3 , a right baffle 5 , a sliding sleeve 6 and a nut 7 .

Among them, the ejector end of the core shaft 4 is provided with a center hole, and the center hole can be supported by the ejector. The clamping end of the core shaft 4 is cylindrical, which is convenient for fixing to the grinder through the clamp provided by the grinder to realize the rotation of the core shaft 4.

Among them, the steel ring 1 is fixedly sleeved on the outside of the ejector end, and a ejector screw 2 is radially inserted into the steel ring 1, so that a bolt axially parallel to the core shaft 4 can be fixed on one end of the ejector of the grinder, and the ejector screw 2 is vertically overlapped on the bolt, so that the rotation of one end of the ejector of the grinder can be realized and the steel ring 1 and the ejector can be driven to rotate synchronously.

The first shoulder is provided near the ejector end on the mandrel 4, that is, a stepped shaft structure. The first shoulder restricts the left baffle 3 movably sleeved outside the mandrel 4 from moving toward the ejector end, and the left baffle 3 is sleeved into the mandrel from the clamping end.

The right baffle plate 5 and the left baffle plate 3 are provided with a shock-absorbing layer on a pair of opposite sides, and the grinding product is placed between the two shock-absorbing layers on the core shaft 4; the shock-absorbing layer is preferably rubber. The right baffle plate 5 and the left baffle plate 3 are metal ring structures, and the rubber is fixedly attached to the metal ring.

Among them, a thread matching with the nut 7 is arranged at the clamping end close to the core shaft 4, and the sliding sleeve 6 is pressed against the grinding product under the action of the nut 7.

It is easy to imagine that the diameter of the grinding product is larger than the outer diameter of the right baffle 5 and the left baffle 3, so as to obtain more grinding operation space, fit the grinding product between the two shock-absorbing layers, and reduce the vibration of the grinding product; at the same time, the position of the right baffle is fixed by the sleeve and the nut, rather than using a nut to fix the position of the right baffle, so that the fixing effect of the right baffle is better. This is because if the baffle 5 is subjected to the vibration transmitted by the grinding product, the nut will vibrate, and the locking effect will be poor. The sleeve 6 weakens the vibration force on the nut 7; for longer grinding products, the grinding product may be pressed onto the thread, and the product will vibrate, which will damage the thread in the long run; because the axial position of the nut 7 at one end is adjustable, and the sleeve can be used for grinding products of different lengths.

Preferably, the grinding vibration reduction device includes a plurality of sleeves 6 of different axial lengths, and one of the sleeves 6 is connected to the outside of the mandrel 4. In this way, when grinding products of different lengths are used, the position of the right baffle 5 is different because the position of the thread is fixed, but the length of the grinding products is different, so the matching sleeve 6 is selected to adjust the distance between the right baffle 5 and the nut 7.

The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
