Abstract

The utility model discloses a tenon. The tenon comprises a tenon. An upper end and a lower end of one side of the tenon are provided with inverted angles. An upper end of the other side of the tenon is provided with an inverted angle. And a lower end of the other side of the tenon is a right angle. The inverted angles are of an asymmetric relation. The tenon has a simple structure, is convenient to use, can avoid the phenomenon that a worker places a workpiece in a reverse direction and causes the workpiece discarding, and effectively improves the product quality. The technology can be used even in the non-batch product trial production, so that the development of a tool clamp can be reduced, and the trial product production progress can be accelerated.

Description

A kind of tenon

Technical field

The utility model relates to machining appurtenance field, is specifically related to a kind of tenon.

Background technology

Plate is thin because panel beating has, and yielding characteristic will constantly be carried out checking the configuration and dimensional measurement when causing erection welding, to guarantee the qualified of final products, as long as there is the carelessness of a link will cause product substandard products to occur in this process.For for this problem, most panel beating unit adopts the ruler measurement and positioning to carry out erection welding again, the way of perhaps carrying out erection welding with setting-out location, but above-mentioned process tends to cause production efficiency low, the problem such as easily make mistakes.

We increase the technique tenon in the need erection welding and without the parts of specific (special) requirements now, so that it can position when assemble welding, simultaneously tenon makes things convenient for the workman to carry out welding operation also so that can control by one hand behind the parts assembly, effectively raises operating efficiency.The application of tenon also can be carried out mistake proofing, one almost symmetrical part use complete asymmetric tenon structure, can avoid the workman that part is oppositely placed and cause parts to be scrapped, effectively raise product quality.When the trial production of non-batch, also can use this technique, reduce the development of frock clamp, accelerate the progress of trial product.

The utility model content

The purpose of this utility model provides a kind of tenon, and it can solve existing problem in the background technology effectively.

In order to solve the existing problem of background technology, the present invention by the following technical solutions: it comprises tenon, and the up and down two ends of this tenon one side are provided with chamfering, and the upper end of opposite side is provided with chamfering, and the lower end is the right angle, is asymmetric relation between the described chamfering.

Owing to having adopted above structure, having the utlity model has following beneficial effect:

Simple in structure, easy to use, can avoid the workman that part is oppositely placed the phenomenon that causes parts to be scrapped, effectively raise product quality, even when the trial production of non-batch, also can use this technique, thus the development of minimizing frock clamp, the progress of quickening trial product.

Description of drawings

For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings, wherein:

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

Reference numeral: tenon 1.

The specific embodiment

Referring to Fig. 1, this specific embodiment is by the following technical solutions: it comprises tenon 1, the up and down two ends of these tenon 1 one sides are provided with chamfering, the upper end of opposite side is provided with chamfering, the lower end is the right angle, it is asymmetric relation between the described chamfering, assemble and weld and pass through to increase without the parts of specific (special) requirements the way of tenon at need, so that it can carry out effective location when assemble welding, the while tenon also can make the parts behind the assembly control by one hand, make things convenient for the workman to carry out welding operation, effectively raise operating efficiency, and the application of tenon also can carry out mistake proofing, because most of parts are symmetrical structure, so when using complete asymmetric tenon structure, can avoid the workman that part is oppositely placed and cause parts to be scrapped, effectively raise product quality, when the trial production of non-batch, also can use this technique, reduce the development of frock clamp, accelerate the progress of trial product.

Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.

Claims (1)

1. tenon, it comprises tenon (1), it is characterized in that the up and down two ends of this tenon (1) one side are provided with chamfering, and the upper end of opposite side is provided with chamfering, and the lower end is the right angle, is asymmetric relation between the described chamfering.
