Specific embodiment

Specific embodiment of the invention is described in more detail below in conjunction with schematic diagram.According to following Description and claims, advantages and features of the invention will become apparent from.It should be noted that, accompanying drawing is used Very simplified form and use non-accurately ratio, be only used to conveniently, lucidly aid in illustrating the present invention The purpose of embodiment.

Inventor is designed vibration tong, to overcome existing vibration test high cost, change test side To time-consuming, the shortcoming of product sensitive for damages, it is ensured that the high-quality of vibration test, high efficiency and low cost. But realize that this target is by no means easy, but need a gradually improved process.Inventor is through a large amount of examinations Test, devise five kinds of different vibration tongs.This five kinds of vibration tongs are respectively pin-connected panel vibration tong, T Shape vibration tong, integrated vibration tong, integrated overturning formula vibration tong and combined turnover-type vibration tong, Inventor is progressively improved to the skill of the 5th kind of vibration tong provided in an embodiment of the present invention from the first vibration tong Art scheme, will respectively introduce each technical scheme below.

As shown in figure 1, being pin-connected panel vibration tong in Fig. 1.The vibration tong is by six pieces of flat plate splicings Into hollow-core construction.It specifically includes one piece of base plate, 100, four blocks of side plates 101 and one piece of top board 102, each piece It is bolted between plate.There is mounting hole on base plate 100, mounting hole is also passed through by base plate by bolt 100 fix on a vibration table.The station of fixed product is provided with four blocks of side plates 101 and top board 102, separately The screwed hole of the bolt installation that fixed beam is used is also devised with outward and is installed for vibration acceleration sensor Screwed hole, screwed hole and mounting hole are not illustrated in figure.The material that vibration tong is used is albronze.

For the vibration tong shown in Fig. 1, its vibration force pass order be vibration table → base plate → side plate → Top board → test specimen, now has four roads to transmit, as long as the transmission of one power of any of which goes wrong, all The vibration exciting force distortion that product is obtained can be caused, and then cause test products to simulate the actual work less than vehicle Condition and vibration test is failed, it is therefore desirable to improve.

As shown in Fig. 2 being T-shaped vibration tong in Fig. 2.The vibration tong includes base plate 103 and fixture master Body 104, the integrated structure of the jig main body 104, it can be cube or rectangular structure, and it can Think solid construction.In order to reduce weight, jig main body is internally provided with the lightening hole of cylinder, additionally, Product be fixed on jig main body 104 top surface and four sides, adopted between base plate 103 and jig main body 104 Use multiple bolt connections.There is mounting hole on base plate 103, consolidated base plate 103 through mounting hole by bolt Determine on a vibration table.

The vibration exciting force Email Filtering of T-shaped vibration tong is reduced (for vibration table → base plate → folder The transmission of tool main body → test specimen 3 road), the rigidity and bonding strength of fixture have obtained obvious enhancing.But hair A person of good sense has found to there is also structure problem by T-shaped vibration tong that (exciting force of shake table is by clamp bottom board again It is that weak body drives entity structure that 4 angles are delivered to jig main body, inadvisable), it is therefore desirable to further improve.

As shown in figure 3, integrated vibration tong in Fig. 3.Relative to T-shaped vibration tong, the integration Vibration tong eliminates the base plate of T-shaped vibration tong, only with the jig main body part of integration.Install Hole 105 is located at four angles of jig main body top surface, top surface and bottom surface of the mounting hole 105 through jig main body, And mounting hole 105 is counter bore structure, is fixed on a vibration table jig main body through mounting hole by bolt. Product can be fixed on top surface and four sides.

Compared with T-shaped vibration tong, the vibration exciting force Email Filtering of integrated vibration tong is further obtained (being vibration table → vibration tong → test specimen 2 road transmission) is reduced, clamp structure is abundant and rigid Enough, also further strengthened with the bonding strength of shake table.But inventor still has found, the vibration Fixture there are the replacement of products direction time and long (fix 30 altogether with the top surface of the vibration tong and four sides As a example by individual sample, experiment changes direction and needs to pull down sample and is installed to another face of fixture again to realize product The conversion in direction, once spends 2 minutes and calculates with the dismounting of sample, and 30 samples are accomplished by spending 1 small When, this does not include that product wire harness rearranges time of cost also) and replacing direction be easily caused product and be subject to External force and the problems such as damage (if we realize testing the replacing in direction by changing the direction of shake table, We not only need to take longer time to change the direction of shake table, can also face shake table use level The problem that slide unit back pressure declines), therefore also need to improve.

As shown in figure 4, being integrated convertible vibration tong in Fig. 4.It is the base in integrated vibration tong (length of side is 220mm) the cube integrated overturning vibration tong designed on plinth.Mainly it is improved to integration Fixed on vibration tong vibration tong 4 mounting holes 106 (mounting hole also for counter bore structure, bolt It is arranged in mounting hole, and vibration tong can be fixed on a vibration table) it is designed into by a face of fixture Three adjoining vertical surfaces of fixture, make fixture there is 3 product mounting surfaces and corresponding 3 baseplanes simultaneously. 3 product mounting surfaces of so vibration tong can be respectively mounted 3 products of different directions (needs note Meaning is after product installs upper fixture product, product connector, vibration table, acceleration should be able to be avoided to pass Will not be interfered with each other between sensor)；Vibration tong is all designed with acceleration transducer in 3 product mounting surfaces Installation screwed hole 107 and for fixing the installation screwed hole (not shown) that product wire harness bolt is used；Vibration All of screwed hole has all inlayed firm set on fixture, enables the screwed hole Reusability will not stripped thread.

Improvement is significantly enhanced the efficiency that direction is changed in experiment, direction is changed every time and only needs to dismounting 4 (product being arranged on fixture can be with folder by the bolt of individual fixed vibration tong and the direction of turnover fixture Tool changed direction, therefore replacing construction not over 10 minutes together), product is without repeated disassembled and assembled, product Wire harness is without rearranging.But inventor has found that the fixture there is also the big problem of fixture demand, several The product of each profile is required for making a vibration tong and installs meeting its, cause vibration tong into The problems such as this high and too many fixture is not easy to management is (even if portioned product can be by original fixture On the basis of improve processing and realize installing, but will also result in and leave too many different-diameter on the surface of vibration tong Installation screwed hole, this can be produced, and screwed hole is not easy to differentiate and fixture service life is the problems such as shorten), therefore Require further improvement again.

Inventor is on the basis of above-mentioned four kinds of technical schemes, it is further provided combined turnover-type vibration tong. For combined turnover-type vibration tong, the invention provides various embodiments, will below introduce one by one.
