Description
Technical field
The utility model is related to mechanical detection technical fields, and in particular to a kind of single track helmet impacts testing machine.
Background technology
Helmet impacts testing machine for helmet quality testing is for constantly hitting the helmet so as to the quality to the helmet
The equipment being detected, with the development of science and technology people have higher to the helmet impacts testing machine for being used for helmet quality testing
Requirement.
The existing helmet impacts testing machine for helmet quality testing can only carry out the helmet from some direction mostly
Bump test, it is impossible to bump test comprehensively be carried out to the helmet, so as to easily influence test mass, it is impossible to accurately reflect product
There is flaw and are also not easy to find in quality, the certain positions of product.
Utility model content
The technical problem to be solved by the utility model is to overcome existing technological deficiency, a kind of single track helmet is provided and is hit
Hit testing machine.
Technical problem to be solved in the utility model is realized using following technical solution：
A kind of single track helmet impacts testing machine, including first support bar, second support bar, the first support bar, second
The spaced and parallel setting of supporting rod, first support bar, second support bar lower end are fixedly connected respectively with pedestal, upper end respectively with crossbeam
It is fixedly connected, the pedestal is square platy structure, and vertical through-hole is set up in parallel in the horizontal direction on the crossbeam, is restricted across perpendicular
Clear opening is simultaneously connect with clump weight, and strut is parallel with crossbeam, and strut one end is fixedly connected with first support bar, the other end and sphere
It is fixedly connected, fixed seat sets along sphere excircle and is in same perpendicular with the crossbeam, and the helmet is fixed on described
In fixed seat, since fixed seat can be set along sphere outer circle circumferential direction so that the helmet can arrange or horizontally disposed vertically,
Clump weight above the helmet can be hit with helmet different parts, and comprehensive bump test is carried out to the helmet.
It is further preferred that the peripherally disposed annular groove of outer surface of spheroid, the annular groove with it is described
Crossbeam is located at same perpendicular, is located at circumferentially spaced setting mounting hole in annular groove in sphere.
6-10 mounting hole is arranged at intervals in sphere it is further preferred that stating.
It is further preferred that the strut is elastic telescopicing rod, on the one hand can be reduced using elastic telescopicing rod to avoid goods
When the vibration that generates be transferred to first support bar, on the other hand can adjust horizontal coordinate of the sphere on pedestal.
It is further preferred that being located at setting groove below sphere on the pedestal, the groove radian is slightly larger than the ball
Body radian, to increase the contact surface of pedestal and sphere, the stability of testing machine when ensureing to hit, while extend the use of testing machine
Service life.
It is further preferred that scale coordinate is set respectively, in order to hitting in the first support bar, second support bar
Highly measure.
The beneficial effects of the utility model are：The utility model is made by the way that fixed seat is set along sphere outer circle circumferential direction
The helmet can be arranged or horizontally disposed vertically, the clump weight above the helmet can be hit with helmet different parts
It hits, comprehensive bump test is carried out to the helmet, compared with existing testing machine, structure is more simple, and use is also more convenient.
Description of the drawings
Fig. 1 is utility model diagram；
Fig. 2 is the utility model sphere side view.
Specific embodiment
In order to be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figs. 1-2, a kind of single track helmet impacts testing machine, including first support bar 1, second support bar 2, first
Strut 1,2 spaced and parallel setting of second support bar, first support bar 1,2 lower end of second support bar are fixedly connected respectively with pedestal 3,
Upper end is fixedly connected respectively with crossbeam 4, and pedestal 3 is square platy structure, and vertical through-hole is set up in parallel in the horizontal direction on crossbeam 4
5, rope 7 passes through vertical through-hole 5 and is connect with clump weight 6, and strut 9 is parallel with crossbeam 4, and 9 one end of strut is fixed with first support bar 1
Connection, the other end are fixedly connected with sphere 8, the peripherally disposed annular groove 10 in 8 outer surface of sphere, annular groove 10 and horizontal stroke
Beam 4 is located at same perpendicular, and circumferentially spaced setting mounting hole 11, Ke Yi in annular groove 10 is located in sphere 8
6-10 mounting hole 11 is arranged at intervals in sphere 8, fixed seat 12 is inserted into mounting hole 11, and the helmet 13 is fixed in fixed seat 12,
Since fixed seat 12 can be set along 8 outer circle circumferential direction of sphere so that the helmet 13 can be arranged or horizontally disposed vertically, be located at
The clump weight 6 of 13 top of the helmet can be hit with 13 different parts of the helmet（Including 13 top of the helmet and side）, to the helmet
13 carry out comprehensive bump test, and fixed seat 12 can also take other modes to realize the connection with sphere 8 in the utility model,
As long as it can ensure that fixed seat 12 can set and be in same perpendicular with crossbeam 4 along 8 excircle of sphere can be realized
