Abstract
A kind of test fixture of the utility model.Base of the present utility model is connected with testing table, and pressing plate is connected on base by T-slot internal clamp, and testpieces is connected on pressing plate by securing member.This test fixture structure is simple, this fixture makes serial part, go for the testpieces of any size band lug-mounted, decrease the quantity of the required test fixture of test, save cost of manufacture and process-cycle, decrease the disassembly and assembly time of test fixture in test, a fixture can realize the tests such as the fixing testpieces vibration of all lug-mounteds, impact and acceleration.
Description
Technical field
The utility model is a kind of test fixture, is mainly used in the test such as vibration, impact, acceleration of the testpieces of band lug-mounted.
Background technology
During the tests such as current testpieces carries out vibrating, impact, acceleration, because the installation dimension of mounting ear formula testpieces is not identical, cause existing test fixture to be all special, the testpieces of different size joins special test fixture.
This phenomenon causes the fixture cost tested to increase, and the process-cycle of fixture extends the test period, and during test, fixture disassembly and assembly time increases simultaneously, and a large amount of test fixtures is not easy to store and management.If the position of mounting hole of testpieces and size change, the test fixture supporting with it just needs to carry out reprocessing even scrapping.
This test fixture, be applicable to the testpieces of the band mounting ear of different installation dimension, test fixture self can regulate with applicable different installation dimension testpieces, and adjustment fixture installation direction when not changing testing table state, can complete the vibration of testpieces, impacting all tests of three axis and acceleration six direction.
Utility model content
The purpose of this utility model: design a kind of test fixture.
The technical solution of the utility model: a kind of test fixture, can be arranged on testing table, described test fixture also comprises base (1), pressing plate (2), with mounting hole in the middle of pressing plate (2), threaded hole is arranged at pressing plate (2) top, for installation test part; The upper processing of base (1) at least two T-slot, securing member is made up of screw and nut, shape and the T-slot of head of screw match, head of screw can put into T-slot, and along T-slot activity, screw afterbody stretches out T-slot, the afterbody of screw is used nut screwing clamping through after the mounting hole of pressing plate (2), is fixed in the T-slot of base (1) by pressing plate (2); Pressing plate (2) along T-slot activity, also can move along the length direction of self mounting hole.
The beneficial effects of the utility model: 1) the utility model structure is simple, and processing cost is low, easy to operate; 2) this fixture makes serial part, goes for the testpieces of any size band lug-mounted; 3) decrease the quantity of required test fixture in testpieces process of the test, save cost of manufacture and process-cycle; 4) disassembly and assembly time of test fixture in test is decreased; 5) minimizing of test fixture kind and quantity is convenient to deposit and manage; 6) fixture can complete vibration, impact, all tests of acceleration.
