Abstract

The utility model relates to a device for grinding and polishing the surface of a columnar workpiece; the device is provided with a knife rest which is fixed on a planker, a polishing group is fixedlyarranged on the knife rest and is composed of a polishing disk, a motor and a supporting arm, the polishing disk, the polishing disk is arranged at the end part of a motor shaft, the motor is fixedlyarranged at the end part of the supporting arm, and the supporting arm is arranged on the knife rest by a fixing device. The device has the beneficial effects that: the device can be used for polishing for the surfaces of any workpiece, the practicability is strong, the structure is simple, and the usage and maintenance are convenient; in addition, the disassembly and assembly are convenient without affecting the normal usage of a lathe, the production cost is reduced and the production efficiency is improved.

Description

Columnar workpiece surface finish device

Technical field

The utility model relates to a kind of device that carries out sanding and polishing for columned surface of the work.

Background technology

In the production process of roll, particularly higher to alloy content roll (as 3%Cr, 5%Cr roll) is when quenching, because the alloy content height causes the quenching degree of material good, internal stress is bigger during quenching, control bad words and relatively be easy to generate hardening flaw, in order to prevent to produce hardening flaw, the roughness of roller surface requires more than 1.6 μ m before roller quenching.In general the roughness that roller surface can reach after processing through common turning is about 3.2 μ m, it is also more man-hour high and cost roll surface roughness processing will to be reached turning skill required more than the 1.6 μ m, just waste time and energy and effect not necessarily desirable.Common way is to adopt mill processing to guarantee the requirement of roughness.Because the price of grinding machine is several times of the machine tool price, that have or even more than ten times, corresponding processing cost also differs several times, and operating efficiency is lower, add workpiece between lathe pass on and under the machine machine all to take certain cycle, also reduced operating efficiency.

The utility model content

The utility model provides a kind of device that is used for the polishing of columnar workpiece surface finish at the ineffective shortcoming that wastes time and energy in the above-mentioned technology, and this device is used in particular for the surface finish of roll.

The realization the technical solution of the utility model is as follows:

Columnar workpiece surface finish device, this device has knife rest, knife rest is fixedly installed on the planker, be set with the polishing group on the knife rest, this polishing group is made up of polishing disk, motor, support arm, polishing disk is arranged on the motor shaft end, and motor is fixedly installed on the support arm end, and support arm is arranged on the knife rest by fixture.

Described supporting plate is divided into upper slide rest, middle supporting plate and big palette, and on the supporting plate, middle supporting plate engaging was arranged on the big palette during the upper slide rest engaging was arranged on.

Described fixture is made up of compact heap, bolt, pillar, and compact heap is by being bolted on the knife rest, and pillar is arranged between compact heap and the knife rest.

Described support arm is fixed on the knife rest by compact heap.

Adopted such scheme, columnar workpiece surface finish device, it has polishing disk, utilize motor that this polishing disk is driven, then columnar workpiece is carried out sanding and polishing, regulate support arm and can regulate the position of polishing disk, whole polishing group is arranged on the supporting plate, and supporting plate is divided into upper slide rest, middle supporting plate and big palette, the upper slide rest engaging is arranged on the middle supporting plate, middle supporting plate engaging is arranged on the big palette, and the track along engaging between the planker moves, and realizes the sanding and polishing adjustment to the columnar workpiece of different-diameter, useful benefit of the present utility model is that the polishing on any columnar workpiece surface all can be used, practical, simple in structure, use and safeguard easily; And easy accessibility, can not influence the normal use of lathe, reduced production cost, improved production efficiency.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Among the figure, 1, polishing disk, 2, motor, 3, support arm, 4, compact heap, 5, knife rest, 6, pillar, 7, bolt, 8, upper slide rest, 9, middle carriage, 10, saddle, 11, motor shaft.

The specific embodiment

As Fig. 1, shown in Figure 2, columnar workpiece surface finish device, this device has knife rest 5, knife rest 5 is fixedly installed on the planker, supporting plate is divided into upper slide rest 8, middle supporting plate 9 and big palette 10, upper slide rest 8 engagings are arranged on the middle supporting plate 9, middle supporting plate 9 engagings are arranged on the big palette 10, be set with the polishing group on the knife rest 5, this polishing group is by polishing disk 1, motor 2, support arm 3 is formed, polishing disk 1 is arranged on motor shaft 11 ends, and motor 2 is fixedly installed on support arm 3 ends, and support arm 3 is arranged on the knife rest 5 by fixture, fixture is by compact heap 4, bolt 7, pillar 6 is formed, compact heap 4 is fixed on the knife rest 5 by bolt 7, and pillar 6 is arranged between compact heap 4 and the knife rest 5, and support arm 3 is fixed on the knife rest 5 by compact heap 4.

According to the size adjustment support arm 3 of diameter of work to the appropriate location, support arm 3 and knife rest 5 are fixed together, during burnishing device work, starter motor 2, and by control upper slide rest 8, middle carriage 9 and saddle 10 are regulated the movement locus of polishing disk 1, thereby realize the polishing to surface of the work.
