Abstract
The utility model relates to the technical field of impact tests and discloses a centering device for an impact test. The centering device comprises a positioner and a centering adjusting bolt, wherein the positioner is arranged on a jaw seat of an anvil block; the centering adjusting bolt runs through the positioner and is parallel to the length direction of a jaw; the centering adjusting bolt and the positioner are in threaded connection; and a position at the front end of the centering adjusting bolt on the jaw seat is a centering position of an impact specimen. The centering device has a simple structure, and is low in cost, easy to machine, convenient to operate, energy-saving and environment-friendly; and the centering of the central line of a gap of the impact specimen and the center of the jaw is realized by screwing the centering adjusting bolt, and the specimen is efficiently and accurately positioned so as to ensure that the axis of an impact pendulum greatly passes through the central line of the gap of the impact specimen during impact, so that the accuracy of test results and the impact detection efficiency are improved.
Description
Technical field
The utility model relates to the impulse test technology, particularly relates to a kind of impulse test centralising device.
Background technology
In the present impulse test, generally adopt the impact breach of impact specimen centering piece impact sample to carry out centering.This mode centering mode wastes time and energy, work efficiency is lower, and after the centering, when taking out impact specimen centering piece in the middle of span, easily the impact specimen of centering bumps partially, thereby affects the accuracy of testing result.
The utility model content
The technical matters that (one) will solve
The technical problems to be solved in the utility model is how to improve the problem of the centering accuracy of impact specimen in the impulse test.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of impulse test centralising device, comprise steady arm and centering adjusting bolt, described steady arm is installed on the anvil block jaw seat, described centering adjusting bolt runs through described steady arm and parallel with the length direction of jaw, described centering adjusting bolt adopts with steady arm and is threaded, and the position that is positioned at described centering adjusting bolt front end on the jaw seat is impact specimen centering position.
Wherein, described steady arm comprises locating piece and location briquetting, and described locating piece is fixed on the described jaw seat by the location briquetting, and described centering adjusting bolt runs through described locating piece and parallel with the length direction of described jaw.
Wherein, an end and the locating piece of described location briquetting are fixed, and the other end adopts briquetting to be bolted on the jaw seat briquetting.
(3) beneficial effect
A kind of impulse test centralising device that technique scheme provides, simple in structure, cost is low, easily processing, easy to operate, energy-conserving and environment-protective, the centering adjusting bolt adopts with steady arm and is threaded, by precession centering adjusting bolt with the breach center line of realizing the impact sample and the center line centering of jaw, improved the centering accuracy of sample, during impact so that the impact pendulnm axis breach center line by impact specimen greatly, and then accuracy and the impulse detection efficient of test findings have been improved, this centralising device is to improving high temperature impact, low-temperature impact test result's accuracy is promising obviously, can in 5 seconds, realize quick centring, guarantee impact test temperature, improve the accuracy of test findings.
Description of drawings
Fig. 1 is the front view that a kind of impulse test of the utility model is used centralising device;
Fig. 2 is the vertical view that a kind of impulse test of the utility model is used centralising device.
Wherein, 1, centering adjusting bolt; 2, jaw seat; 3, jaw; 4, impact specimen; 5, locating piece; 6, location briquetting; 7, briquetting bolt; 8, jaw seat briquetting.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Such as Fig. 1 and Fig. 2, wherein, do not place sample among Fig. 1, placed sample among Fig. 2, a kind of impulse test centralising device of the utility model, centralising device comprises steady arm and centering adjusting bolt 1, this steady arm is installed on the anvil block jaw seat 2, centering adjusting bolt 1 runs through steady arm and parallel with the length direction of jaw 3, and centering adjusting bolt 1 adopts with steady arm and is threaded, and the position that is positioned at centering adjusting bolt 1 front end on the jaw seat 2 is impact specimen 4 centering positions.This centralising device that the utility model provides is simple in structure, cost is low, easy processing, easy to operate, energy-conserving and environment-protective, by precession centering adjusting bolt 1 with the breach center line of realizing impact sample 4 and the center line centering of jaw, efficiently and accurately location sample, during impact so that the impact pendulnm axis breach center line by impact specimen 4 greatly, thereby improved accuracy and the impulse detection efficient of test findings; This centralising device obviously can be realized quick centring to the accuracy that improves high temperature impact, low-temperature impact test result is promising in 5 seconds, guarantee impact test temperature, improved the accuracy of test findings.Further, be threaded owing to adopting between centering adjusting bolt 1 and the steady arm, the relation of being threaded connection can accurately be carried out centering.Steady arm positions the position of centering adjusting bolt, and the displacement of restriction centering adjusting bolt left and right directions can only be moved it vertically.
For the centering adjusting bolt is positioned better, the steady arm of the present embodiment comprises locating piece 5 and location briquetting 6, locating piece 5 is fixed on the jaw seat 2 by location briquetting 6, and centering adjusting bolt 1 runs through the locating piece 5 of steady arm and parallel with the length direction of jaw 3.One end of location briquetting 6 and locating piece 5 are fixing, and the other end adopts briquetting bolt 7 to be fixed on the jaw seat briquetting 8.Jaw seat briquetting 8 is bolted on the shock machine anvil block.
A kind of impact specimen that technique scheme provides with the course of work of centralising device is, because impact specimen 4 is standard component, at first centering adjusting bolt 1 stretches out that (this ad-hoc location is so that with impact specimen 4 during near centering adjusting bolt 1 front end so that this centering adjusting bolt 1 front position is positioned at an ad-hoc location, the breach center line of impact specimen 4 and the center line centering of jaw 3 are overlapping), anchor clamps gripping impact specimen 4 is put into, and so that the end of the end of impact specimen 4 and centering adjusting bolt 1 near finishing centering location, because the chuck of anchor clamps is less, in the jaw span, can conveniently come in and go out and impact specimen 4 can not bumped partially, at this moment, the end of impact specimen 4 is subject to the restriction of centering adjusting bolt 1, because jaw seat 2 is L shaped, so the bottom of impact specimen 4 and a side are subject to the restriction of jaw seat 2.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
