Description

Roundness detection scriber for water pump runner chamber

Technical Field

The utility model relates to a scriber especially relates to a water pump runner room circularity detects scriber.

Background

At present, when the roundness of a blank of a water pump runner chamber or stainless steel after surfacing is detected, the roundness is generally detected on a large vertical lathe or a three-coordinate measuring instrument due to the large diameter. And when the roundness is detected on a large vertical lathe, the processing equipment is occupied, and the consumed time is long. When the three-coordinate measuring instrument is used for detecting the roundness, the price of the adopted detecting instrument is high, so that the detection cost is high.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the defects of the prior art, the utility model provides a water pump runner room roundness detection scriber.

The technical scheme is as follows: the utility model discloses a water pump runner chamber roundness detection scriber, which comprises a stand column, a slide block, a cross rod, a scriber, a rotating assembly and a base; the upright post rotates through the rotating component;

the sliding block is fixed on the upright post, and the position of the sliding block is adjustable; the cross bar is fixed on the sliding block; the scriber is positioned on the cross bar;

the rotating assembly comprises a bearing, a bearing seat, an upper bearing cover and a lower bearing cover, wherein the bearing seat is fixed on the base through the lower bearing cover.

The cross rod adopts a telescopic rod with a telescopic function so as to measure the roundness of water pump runner chambers or other rotary workpieces with different diameters.

The slider is equipped with the locking groove that opens and shuts, and the slider is fixed on the stand through the locking groove that opens and shuts.

The sliding block is fixed on the upright post through a screw, the screw is loosened, and the position of the sliding block on the upright post is moved, so that the height adjustment can be realized.

Has the advantages that: compared with the prior art, the utility model discloses can the accurate circularity that detects the runner room, and simple structure, low cost, convenient operation.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a sectional view taken along line a-a of fig. 1.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses water pump runner room circularity detects scriber, including stand 1, slider 2, screw 3, horizontal pole 4, scriber 5, base 10 and rotating assembly, this rotating assembly includes bearing 6, bearing frame 7, upper bearing cap 8 and lower bearing cap 9.

A pair of bearings 6 is installed at the lower end of the upright post 1, the bearings 6 are installed in a bearing seat 7, an upper bearing cover 8 and a lower bearing cover 9 are connected with the bearing seat 7 in a matching mode, and the bearing seat 7 is fixed on a base 10 through the lower bearing cover 9. The upright post 1 rotates through the bearing 6, and then drives the scriber to horizontally rotate around the upright post.

The upright post 1 is provided with a slide block 2, and the slide block 2 is locked by a screw 3. The telescopic rod 4 is arranged in the slide block 2 and is fixed by a screw. The end of the cross rod 4 is provided with a scriber 5.

The sliding block 2 is provided with an opening and closing locking groove, the screw is loosened, and the position of the sliding block 2 on the upright post 1 is moved, so that the height adjustment can be realized. The cross rod 4 adopts a telescopic rod with a telescopic function so as to measure the roundness of water pump runner chambers or other rotary workpieces with different diameters. The bearing 6 is a rolling bearing.

During detection, a water pump runner chamber after surfacing is arranged on a detection platform, a roundness detection scriber 5 is placed in the detection platform, the contact condition of the four node positions in the cross direction of the roundness detection scriber 5 and the runner chamber is detected, the relative position of the roundness detection scriber and the water pump runner chamber is aligned, the scriber is rotated, and the maximum gap between the scriber and the runner chamber is measured to obtain the roundness of a detected section. After measuring one section, the slide block 2 is moved up and down, and the roundness of the other section can be measured after the screw 3 is locked.

The scribing needle is removed, the dial indicator is installed, and the roundness of the finished product runner chamber can be accurately checked.
