Description

Special detection tool for coupler

Technical Field

The utility model relates to a fluid engineering class product detection area specifically is a utensil is examined in coupler special use.

Background

Along with the application and development of hydraulic engineering, pollution discharge engineering, petrochemical engineering, fluid engineering and the like, the demand of fluid conveying equipment is greater and greater, the quality requirement is also higher and higher, in order to meet the overall performance requirement of the conveying equipment, the processing precision of key parts must meet the design requirement, and the coupler is the key part with higher precision in the fluid conveying equipment. It is particularly important to identify whether the accuracy of the coupling meets design requirements, particularly the coaxiality and run-out detection of the coupling. In the detection of coaxiality and jitter of the coupler, the traditional detection method is three-coordinate detection, although the detection method can accurately detect errors and conformity of parts, the detection method has the obvious defects of very low detection speed and high cost, so that the detection method can only realize detection of a small number of parts, cannot realize large-scale detection, and is difficult to meet the requirements in practical production.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an utensil is examined in coupler special use to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a utensil is examined in coupling special use, includes the backup pad, the backup pad lower left corner fixed mounting has the table support, the percentage table is installed on table support upper end right side, be equipped with "V" shape groove in the middle of the backup pad upper end, the locating pin is installed to backup pad "V" shape inslot symmetry, the bearing is installed to the locating pin upper end, and adjusting screw is installed at backup pad upper end back, adjusting screw passes through lock nut to be fixed in the backup pad, the locating pin lower extreme passes through fixation nut to be fixed in the backup pad.

Further: the positioning pins are symmetrically distributed on the axis of the V-shaped groove, and bearings are arranged on every two positioning pins which are symmetrical by the axis as a group.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model solves the problem of detecting the coaxiality and the run-out degree of the connector parts; the problems that the traditional three-coordinate detection method is time-consuming and labor-consuming, high in cost and incapable of batch detection are solved; the utility model has high accuracy and high detection speed, can realize the on-site detection of an operator, does not need to be shut down, and does not increase extra labor cost; the utility model is simple and convenient to operate, and can be operated by only one example without special training; the utility model discloses can realize the big batch in the trade and detect.

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

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

In the figure: 1. the device comprises a supporting plate, 2 percent meters, 3 percent meters, a meter support, 4 percent positioning pins, 5 percent bearings, 6 percent adjusting screws, 7 percent locking nuts, 8 percent fixing nuts.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides an utensil is examined in coupler special use, includes

backup pad

1, 1 lower right corner fixed mounting of backup pad has table support 3, and the table support is a set of hinge bar: the magnetic coupling device comprises two coupling rods and two hinges, wherein the lower ends of the hinge rods are connected with a magnetic meter base, the upper ends of the hinge rods are connected with a dial indicator, and the length of the hinge rods and the direction of the dial indicator at the upper ends of the hinge rods can be changed by adjusting the connection mode of the two coupling rods and the two hinges. The table supporting structure is the prior art, and its model is: CZ-6A. The dial indicator 2 is installed on the right side of the upper end of the indicator support 3, a V-shaped groove is formed in the middle of the upper end of the supporting plate 1, the positioning pins 4 are symmetrically installed in the V-shaped groove of the supporting

plate

1, 6 groups of pin holes are machined in the V-shaped groove and used for installing the positioning pins, the bearing 5 is installed at the upper end of the positioning pin 4, the positioning pins are made into a step shape, the upper end diameter of the positioning pin is matched with the inner holes of the bearing and used for assembling the bearing, the middle diameter of the positioning pin is matched with the pin holes and used for being installed in the pin. Adjusting screw 6 is installed at two angle departments back in backup pad 1 upper end, adjusting screw 6 passes through lock nut 7 adjusting position, realizes the adjustment of the contained angle of backup pad 1 and horizontal direction, and then adjusts the position of backup pad 1. The lower end of the positioning pin 4 is fixed on the support plate 1 through a fixing nut 8.

The positioning pins 4 are symmetrically distributed on the axis of the V-shaped groove, and bearings 5 are arranged on every two positioning pins which are symmetrical on the axis as a group.

Use the utility model discloses the time, earlier with backup pad 1 through adjusting screw 6 and lock nut 7 adjust a suitable position, then install bearing 5 on corresponding size's locating pin 4, then install bearing 5 with the work piece on, because the external diameter/internal diameter of action of gravity work piece compress tightly the bearing, inspect through percentage table 2 on the regulation support 3 at last.

The working process is as follows:

the workpiece is placed under the supporting plate, the lower end face of the workpiece is attached to the supporting plate, the outer diameter of the workpiece measurement datum is attached to the two bearings at the same time, the measuring head of the dial indicator is adjusted to be attached to the outer diameter/inner diameter or the end face of the workpiece to be measured, the workpiece is rotated for 360 degrees, the outer diameter/inner diameter of the workpiece datum must be attached to the two bearings in the rotating process and cannot be separated, and the reading of the pointer of the dial indicator is observed at the moment, namely, the measured value.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
