Description

Special detection tool for train support

Technical Field

The utility model relates to a machining makes technical field, in particular to train support special use detection instrument.

Background

The train support belongs to vehicle engineering machinery parts, the structure is relatively complex, the product is extremely easy to deform in the production process, the size needs to be detected before warehousing, and the casting needs to be corrected if the product deforms so as to reach the qualified size. The arc surface of the product is not only a clearance fit surface when a customer loads a car, but also a fine-machined blank positioning surface, the requirement on the size of the arc is very strict, the requirement on the size of the arc reaches R3500/+0.5, and the surface quality is not accurate and has any unevenness. The existing detection means mostly use the conventional means detection tools manually, such as a vernier caliper, a three-coordinate system and the like. However, the product is produced in large scale, and in the process of detecting the size of the product, the vernier caliper is used for detecting the part, so that the operation is complicated, the error is large, great inconvenience is brought to subsequent size correction and repair, and the production efficiency is low; by using three-coordinate detection, relatively accurate size data can be obtained, but the working efficiency is very low, the detection cost is too high, and the requirement of mass production cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a special detection instrument of train support can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a special detection instrument of train support, includes the base down, the up end one end fixed connection L type support frame of base down, threaded connection threaded rod on the crossbearer of L type support frame, the upper end fixed connection rotary disk of threaded rod, the lower extreme fixed connection upper cover plate of threaded rod, the lower terminal surface of upper cover plate passes through cylinder fixed connection and detects the arc piece, the train support foundry goods is placed to the up end of base down, the arcwall face of train support foundry goods corresponds the setting with the arcwall face that detects the arc piece.

Preferably, the surface of the arc surface of the detection arc block is a wear-resistant layer.

Preferably, the surface of the arc surface of the detection arc block is subjected to quenching treatment.

Preferably, the upper end face of the lower base is positioned on two symmetrical and fixed connecting limiting columns on two sides of the train support casting.

Preferably, the limiting column is in threaded connection with the lower base, and a plurality of threaded holes in threaded connection with the limiting column are formed in the upper end face of the lower base.

Preferably, the cylinders are four and distributed in a rectangular array.

Compared with the prior art, the utility model discloses the beneficial effect who produces is: the utility model discloses a waiting to detect the foundry goods and putting in base up end of going to the bottom, under detecting the arc piece, slow rotatory rotary disk makes the circular arc contact on the anterior circular arc of detection arc piece and the foundry goods, looks over the clearance of contact surface after the contact, if have the clearance then this arc surface of foundry goods need polish with grinding tool, otherwise then qualified, the utility model is convenient for operation, can be quick, accurate detect out the part size, detection efficiency is high, is particularly useful for big batch product detection.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-2, a special detection instrument of train support, includes lower base 8, lower base 8's up end one end fixed connection L type support frame 6, threaded connection threaded rod 1 on the crossbearer of L type support frame 6, the upper end fixed connection rotary disk 5 of threaded rod 1, threaded rod 1's lower extreme fixed connection upper cover plate 2, the lower terminal surface of upper cover plate 2 passes through 3 fixed connection detection circular arc pieces 4 of cylinder, train support foundry goods 7 is placed to lower base 8's up end, the arcwall face of train support foundry goods 7 corresponds the setting with the arcwall face that detects circular arc piece 4.

In this embodiment, the arc surface of the detection arc block 4 is a wear-resistant layer.

In this embodiment, the arc surface of the arc block 4 is subjected to quenching treatment.

In this embodiment, the upper end surface of the lower base 8 is located on two symmetrical fixed connection limiting columns 9 of the train support casting 7.
