Abstract

The utility model discloses a spindle box grinding rod, which comprises a main body, a locating sleeve and a grinding consumption sleeve. The locating sleeve and the grinding consumption sleeve are connected together through the main body, a bearing hole at one end of the spindle box is used for locating and grinding the other end thereof, then the locating part and the grinding part is exchanged, therefore excellent proper alignment can be achieved for the front and the rear bearings. The locating sleeve and the grinding consumption sleeve can be changed in accordance with the size of the spindle box, therefore the material is saved, application and keeping become fairly convenient, the labor intensity of operating staff is reduced, the work efficiency is improved, and the manufacturing cost of machine tools is greatly saved.

Description

The main spindle box grinding rod

Technical field:

The utility model is the exigent specific purpose tool of a kind of Lathe Spindle Box front and back bearings hole axiality, specifically is a kind of main spindle box grinding rod, and it is particularly suitable for numerically controlled lathe.

Background technology:

Present numerical control turning machine develops to high speed, high accuracy direction, and the required precision of main shaft is very high, and the circular runout of some main shaft requires to reach the um level, and for reaching so high precision of main shaft, the axiality of the front and back bearings of main shaft necessarily requires fine.

Summary of the invention:

Goal of the invention: the purpose of this utility model is to require very highly at the main spindle box axiality, under the situation of the restriction of the deficiencies in the prior art and equipment, provides a kind of simple in structure, easy to use and reliable main spindle box grinding rod.

Technical scheme: a kind of main spindle box grinding rod described in the utility model, comprise the grinding rod main body, grind to consume and overlap, the front and back locking nut, positioning sleeve and handle, described grinding consumes and is enclosed within grinding rod main body leading portion, by locking nut locking, positioning sleeve is enclosed within grinding rod main body back segment respectively in its both sides, and handle (6) is fixed on the grinding rod body rear and drives the rotation of grinding rod main body.

The grinding rod main body preferably has tapering at the position that grinding consumption cover is installed.

This grinding rod comprises that mainly main body, positioning sleeve and grinding consume cover three parts and form, and positioning sleeve and grinding consume cover and link together by main body, on main body, can consume cover with changing positioning sleeve with grinding according to the size of main spindle box.Often use grinding to consume cover, grind to consume and overlap and to wear and tear,, can normally use again by adjusting locking nut.Thereby saved material, and easily processing, it is convenient especially to use, copy mechanically, take care of, and has alleviated labor intensity of operating personnel, has improved operating efficiency, has saved a large amount of lathe manufacturing costs.

The utility model compared with prior art has following advantage: 1, easy to operate, cost is low, make front and back bearings reach very high axiality.2, simple in structure, easy to use, dependable performance.

Description of drawings:

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

The specific embodiment:

As shown in Figure 1, main spindle box grinding rod described in the utility model comprises main body 1, locking nut 2, grinds consumption cover 3, locking nut 4, positioning sleeve 5, handle 6.Main body 1 is a conical form in that the position of grinding consumption cover 3 is installed, grinding consumption cover 3 installs on the main body 1, load onto alignment pin and tighten locking nut 2 and 4, then load onto positioning sleeve 5, handle 6 then just can be with the end location in front and back bearings hole, the other end grinds, change a direction then and grind, the front and back bearings hole just can have been ground, and the axiality in two holes can reach very high precision.Often use is ground and is consumed cover 3, and grinding consumption cover 3 must wear and tear, by adjusting locking nut, need not to change to grind to consume to overlap and normally to use again, and, that is to say that the D1 among the figure is different with D2 for different main spindle boxes, oneself can change and grind consumption cover 3 and positioning sleeve 5.

Claims (2)

1, a kind of main spindle box grinding rod, it is characterized in that: comprise grinding rod main body (1), grind to consume and overlap (3), front and back locking nut (2,4), positioning sleeve (5) and handle (6), described grinding consumes cover (3) and is enclosed within grinding rod main body (1) leading portion, by locking nut (2,4) locking, positioning sleeve (5) is enclosed within grinding rod main body (1) back segment respectively in its both sides, and handle (6) is fixed on grinding rod main body (1) rear end and drives the rotation of grinding rod main body.

2, main spindle box grinding rod according to claim 1 is characterized in that: grinding rod main body (1) has tapering at the position that grinding consumption cover (3) is installed.
