Description

Impact test auxiliary positioning device

Technical Field

The utility model relates to the field of auxiliary test equipment, in particular to an auxiliary positioning device for impact test.

Background

The impact tester is a material tester for applying an impact test force to a sample to perform an impact test. The impact testing machine is divided into a manual pendulum impact testing machine, a semi-automatic impact testing machine, a digital display impact testing machine, a microcomputer control impact testing machine, a drop hammer impact testing machine, a nonmetal impact testing machine and the like. When the impact resistance of the metal material under dynamic load is measured, a pendulum impact tester is adopted, the pendulum impact tester is used for positioning the sample with the V-shaped notch, in the actual test process, the pendulum is difficult to strike accurately when striking the V-shaped notch, and the test data is often inaccurate.

Disclosure of Invention

The utility model aims at the problems in the prior art, and specifically designs an auxiliary positioning device for impact test, which ensures accurate positioning.

In order to achieve the above purpose, the utility model provides an auxiliary positioning device for impact test, which comprises a distance span plate, wherein the distance span plate is provided with a positioning pin matched with a V-shaped notch on a sample.

By adopting the technical scheme, the positioning work of the impact test sample is finished together through the distance span plate and the positioning pin, the effect of quick and accurate positioning is achieved by utilizing the tangency of the positioning pin and the V-shaped notch, and the positioning device is simple in structure, convenient to use and accurate in positioning.

Further, the two opposite distance edges of the distance span plate are parallel, the distance between the two opposite distance edges is the same as the set distance between the two clamping blocks on the impact testing machine, the locating pin penetrates through the distance span plate, and the locating pin is equal to the distance between the two opposite distance edges.

According to the technical scheme, two relatively parallel distance edges of the distance span plate are abutted against the clamping blocks on the impact testing machine, and then the test sample can be rapidly positioned at the position where the distance edges of the V-shaped notch are equal to each other through the tangency of the positioning pin arranged on the clamping blocks and the V-shaped notch, and the pendulum bob can accurately impact the V-shaped notch to ensure that the test is smoothly carried out.

Further, a handle is further mounted on the distance span plate, and the handle is not intersected with the opposite distance edges.

Further, the handle is connected with the distance span plate through a connecting pin.

By adopting the technical scheme, the distance span plate is connected with the handle through the connecting pin, and an operator can lean against the two clamping blocks through holding the handle by hand, so that the positioning is more convenient and quicker.

Further, a connecting groove is formed in one end, close to the distance span plate, of the handle, and the distance span plate is installed in the connecting groove in an adaptive mode and is connected through the connecting pin; the number of the connecting pins is not less than two.

In summary, the utility model has the following advantages and beneficial technical effects: the auxiliary positioning device for impact test has the advantages of simple structure, easy material drawing and manufacturing, high positioning precision and high efficiency of positioning samples, and is very suitable for popularization and application.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1 to 3, an impact test auxiliary positioning device includes: the handle 1 is square steel, a mounting groove is formed in one end office of the handle 1, two through holes are formed in two parallel surfaces of the mounting groove, and the through holes penetrate through the mounting groove.

As shown in fig. 2, the middle of the distance span plate 2 is inserted into the mounting groove and is fixedly connected with the handle 1 through two connecting pins 4, the positioning pin 3 penetrates through and is fixedly mounted on the distance span plate 2, the positioning pin 3 is positioned on the central line of the long side of the distance span plate 2 and is positioned between the long side of the distance span plate 2 which is not inserted into the mounting groove and the top surface of one end of the handle 1 provided with the mounting groove.

The diameter of the locating pin 3 is in tangential fit with the V-shaped notch on the sample.

As shown in fig. 3 to 6, the working principle of the auxiliary positioning device for impact test of the utility model is as follows:

the clamping blocks on the test bed should be adjusted in position in advance, and the length of the long side of the distance span plate 2 of the positioning device is equal to the distance between the two clamping blocks; when an impact test is needed, an operator holds the handle 1, clamps the distance span plate 2 between the two clamping blocks, at the moment, the position of the positioning pin 3 corresponds to the striking position of the pendulum bob, a sample with a V-shaped notch leans against the clamping blocks, the V-shaped notch is positioned to a designated position by the tangential action of the positioning pin 3 and two inclined planes of the V-shaped notch, and then the positioning device is taken away from the left side to perform the impact test.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
