Description

Grinding tool for tool rest

Technical Field

The utility model relates to a frock especially relates to a knife rest is with grinding frock.

Background

The tool post on the numerical control machine tool is an important part for placing the tool, and many tool posts also directly participate in cutting work, such as a square tool post on a horizontal lathe, a turret tool post of a turret lathe, a return pulley tool post of a return pulley type turret lathe, a turret tool post of an automatic lathe, a balance tool post and the like. These tool holders, which both hold the tools and are involved directly in the cutting, are subjected to extreme cutting forces, so that they often become a weak link in the process system. With the development of automation technology, there are many changes to tool holders of machine tools, especially the automatic tool holder using electric (hydraulic) transposition and the two rotary cutter heads used in numerically controlled lathe. The machining center further adopts a tool magazine and a tool changing manipulator, so that the functions of storing tools in large capacity and automatically exchanging the tools are realized, the number of the tools placed in the tool magazine is from dozens to hundreds, and the time for automatically exchanging the tools is reduced from tens of seconds to several seconds or even to a few tenths of seconds, so that the performance and the structure of the tool rest directly influence the cutting performance and the cutting efficiency of the machine tool and embody the design and manufacturing technical level of the machine tool. Wherein, roughness and axiality in shaft hole play crucial effect to machining precision and efficiency on the knife rest, and the shaft hole in the current knife rest is for reaching required roughness, generally adopts the mode of grinding the shaft hole with the help of the grinding rod to current shaft hole uses in groups usually, then need grind respectively to two shaft holes in a set of, and not only wastes time and energy, is difficult to guarantee simultaneously that the roughness after grinding meets the requirements, and adopts the mode of grinding respectively, hardly guarantees the axiality requirement in two shaft holes.

Disclosure of Invention

According to the technical problem above, the utility model provides a knife rest is with grinding frock, including grinding main shaft, first sleeve, second sleeve, grinding groove, gasket, lock sleeve, lock nut, the grinding main shaft both ends overlap respectively has first sleeve, second sleeve, the inside packing of first sleeve, second sleeve has the abrasive sand, be equipped with grinding groove on first sleeve, the second sleeve respectively, grinding groove quantity is N, and N is greater than or equal to 6, and N is ground equidistant distribution in first sleeve, second sleeve periphery, both sides are equipped with the lock sleeve respectively around first sleeve, the second sleeve, be equipped with the gasket between lock sleeve and first sleeve, the second sleeve, the lock sleeve outer end is equipped with lock nut.

Furthermore, the cross sections of the first sleeve and the second sleeve are both in an isosceles trapezoid structure.

Further, the diameter of the grinding sand is smaller than the width of the grinding groove.

The utility model has the advantages that: the utility model relates to a knife rest is with grinding frock, through designing a grinding frock, the shaft hole on the knife rest is ground, at first sleeve during the use, it has the abrasive sand to fill respectively in the second sleeve, the first shaft hole of tool setting advance knife rest will be ground, the second shaft is downthehole, it is located first shaft hole to rotate the grinding main shaft, position between the second shaft hole, can be effectual to first shaft hole, the downthehole wall of second shaft grinds, the abrasive sand has increased first sleeve and first shaft hole, frictional force between second sleeve and the second shaft hole, through grinding repeatedly, make first shaft hole, the roughness in second shaft hole reaches required standard, time saving and labor saving, and grind the diaxon hole simultaneously, can guarantee the axiality requirement in two shaft holes.

Drawings

Fig. 1 is a main structure diagram of the present invention.

As shown in the figure, the grinding machine tool comprises a tool rest-1, a first shaft hole-2, a second shaft hole-3, a grinding tool-4, a grinding main shaft-401, a first sleeve-402, a second sleeve-403, a grinding groove-404, a gasket-405, a locking sleeve-406 and a locking nut-407.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings: the utility model relates to a knife rest is with grinding frock, including grinding main shaft 401, first sleeve 402, second sleeve 403, grinding groove 404, gasket 405, lock sleeve 406, lock nut 407, grinding main shaft 401 both ends overlap respectively has first sleeve 402, second sleeve 403, the inside packing of first sleeve 402, second sleeve 403 has the abrasive sand, be equipped with grinding groove 404 on first sleeve 402, the second sleeve 403 respectively, grinding groove 404 quantity is N, and N is greater than or equal to 6, and the equidistant distribution of N grinding groove 404 is in first sleeve 402, second sleeve 403 periphery, both sides are equipped with lock sleeve 406 respectively around first sleeve 402, the second sleeve 403 sleeve, be equipped with gasket 405 between lock sleeve 406 and first sleeve 402, the second sleeve 403, lock sleeve 406 outer end is equipped with lock nut 407.

Further, the cross sections of the first sleeve 402 and the second sleeve 403 are both isosceles trapezoid structures.

Further, the diameter of the grinding sand is smaller than the width of the grinding groove 404.

The working principle is as follows: firstly, filling a proper amount of grinding sand in the first sleeve 402 and the second sleeve 403 respectively, and assembling the tool body 4 on the tool rest 1, wherein the specific operations are as follows: the grinding main shaft 401 is arranged from one end of the second shaft hole 3, the first sleeve 402 and the second sleeve 403 are respectively positioned at the positions of the first shaft hole 2 and the second shaft hole 3, the gasket 405 and the locking sleeve 406 are sequentially arranged, the parts are locked through the locking nut 407, the grinding main shaft 401 is rotated to be positioned at the positions between the first shaft hole 2 and the second shaft hole 3, the inner walls of the first shaft hole 2 and the second shaft hole 3 can be simultaneously ground, the friction force between the first sleeve 402 and the first shaft hole 2 and between the second sleeve 403 and the second shaft hole 3 is increased through the grinding sand, the grinding force is increased, the grinding effectiveness is guaranteed, the first shaft hole 2 and the second shaft hole 3 of the tool rest can be simultaneously ground through the tool, and finally the roughness of the inner wall and the coaxiality of the two shaft holes meet the standard.

Through the utility model discloses first shaft hole, the downthehole wall of secondary shaft on the tool setting frame can be effectively ground, through grinding repeatedly, make the roughness in first shaft hole, secondary shaft hole reach required standard, labour saving and time saving to grind the diaxon hole simultaneously, can guarantee the axiality requirement in two shaft holes.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
