Abstract

The verticality detection tool comprises a baffle, a V-shaped block, a dial indicator and a bedplate, wherein the V-shaped block and the baffle are placed on the bedplate, the baffle is located behind the V-shaped block, a U-shaped groove is formed in the baffle and is perpendicular to the V-shaped block, and a detection head of the dial indicator horizontally penetrates through the U-shaped groove and can move up and down in the U-shaped groove. Utilize the utility model discloses can detect out whether corresponding straightness that hangs down is in qualified scope, measuring time is short to measurement accuracy is high.

Description

Perpendicularity detection tool

Technical Field

The utility model relates to a detection device for motor manufacturing specifically relates to a stator casing terminal surface and excircle straightness that hangs down detect frock.

Background

In the motor manufacturing industry, before the stator casing is assembled, the perpendicularity between the end surface of the stator casing and an outer circle needs to be checked, and the method for measuring the perpendicularity is as follows: firstly, a vertical device for connecting a flat plate and a vertical plate is manufactured, the end face of a stator casing is placed on the flat plate, the outer circle surface of the stator casing is attached to the vertical plate, and a clearance between the outer circle of the casing and the vertical plate is measured by a feeler gauge.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that, overcome the defect that prior art exists, provide a hang down straightness detection frock that measuring time is short and measurement accuracy is high.

The utility model provides a technical scheme that its technical problem adopted is: the verticality detection tool comprises a baffle, a V-shaped block, a dial indicator and a bedplate, wherein the V-shaped block and the baffle are placed on the bedplate, the baffle is located behind the V-shaped block, a U-shaped groove is formed in the baffle and is perpendicular to the V-shaped block, and a detection head of the dial indicator horizontally penetrates through the U-shaped groove and can move up and down in the U-shaped groove.

Further, the baffle and the V-shaped block are fixedly connected through a first screw.

Further, the V-shaped block and the bedplate are fixedly connected through a second screw.

Compared with the prior art, the utility model has the advantages as follows:

the stator casing is placed on the V-shaped block, then the detection head of the dial indicator horizontally penetrates through the U-shaped groove in the baffle plate to be in contact with the end face of the stator casing, the detection head of the dial indicator can move up and down in the U-shaped groove, the stator casing rotates for a circle, and whether the corresponding verticality is in a qualified range can be detected.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a left side view of the embodiment of the present invention.

In the figure, 1, a baffle, 1.1, a U-shaped groove, 2, a stator shell, 3, a V-shaped block, 4, a first screw, 5, a bedplate, 6, a second screw, 7 and a dial indicator are arranged.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, the embodiment includes a baffle 1, a V-shaped block 3, a dial indicator 7 and a platen 5, the V-shaped block 3 and the baffle are placed on the platen 5, the baffle 1 is located behind the V-shaped block 3, a U-shaped groove 1.1 is formed in the baffle 1, the U-shaped groove 1.1 is perpendicular to the V-shaped block 3, a detection head of the dial indicator 7 horizontally penetrates through the U-shaped groove 1.1 and can move up and down in the U-shaped groove 1.1, the baffle 1 and the V-shaped block 3 are fixed by a first screw 4, and the V-shaped block 3 and the platen 5 are fixed by a second screw 6.

Referring to fig. 1, the operation is as follows: placing the stator shell 2 in the V-shaped block 3, and attaching the detected end face of the stator shell 2 to the baffle 1; a dial indicator 7 with a magnet support is placed on the bedplate 5, a detection head of the dial indicator 7 vertically and lightly touches the end face of the stator casing 2 through a U-shaped groove of the baffle plate 1, then the casing is rotated for a circle, and whether the verticality is in a qualified range is judged according to the swinging condition of a pointer of the dial indicator 7.

Various modifications and variations of the present invention may be made by those skilled in the art, and they are within the scope of the present invention provided they are within the scope of the claims and their equivalents.

What is not described in detail in the specification is prior art that is well known to those skilled in the art.
