Description
Technical field this utility model is related to drop weight test mechanism, more particularly to a kind of drop hammer tester guiding mechanism.
Background technology
In testing of materials industry, drop hammer impact testing machine is to carry out impact examination to samples such as metal, plastics, composites
Test and a kind of quite extensive special equipment of application, and ejection mechanism is then one of part of most critical on drop hammer tester.Mesh
On front market, popular drop hammer tester provides impulsive force by the freely falling body of weight block, and weight block is by leading boots and cunning
Rail connects, and friction loss is big, and test accuracy is not high and unstable.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of drop hammer tester guiding mechanism.
This utility model solves the technical scheme adopted by its technical problem：A kind of drop hammer tester guiding mechanism, bag
The weight frame for being vertically directed bar, erection weight block for including two vertically and be arrangeding in parallel, it is described to be vertically directed bar for cylindrical light
Bar, eight drift angles of the weight frame are respectively provided with a roller, the pivot center of the roller and the axis for being vertically directed bar
Antarafacial is vertical, and the periphery of the roller is in the outer circumference surface laminating for being vertically directed bar, described to be vertically directed on bar along institute
State and be vertically directed pole length direction and be spaced for detecting the position sensor of the weight rack position.
Clamped using the roller of eight drift angles of weight frame in above-mentioned design and be vertically directed bar, simple structure, frictional resistance are little,
Operate steadily, reduce impact of the frictional force to test accuracy, position sensor is easy to the detection to weight rack position.
Used as the further improvement of the design, the roller includes the dead axle being arranged on the weight frame, is arranged on institute
The roller body on dead axle is stated, is easily installed.
Used as the further improvement of the design, the roller body is bearing, long service life, high precision.
As the further improvement of the design, eccentric bushing on the dead axle, is threaded with, the roller body is arranged on institute
State on eccentric bushing, be conveniently adjusted roller body and the gap being vertically directed between bar, improve the stability of weight frame, reduce energy and damage
Lose.
As the further improvement of the design, eccentric bushing is provided with front side of the weight frame or in the four rolling of rear side, just
In regulation.
The beneficial effects of the utility model are：This utility model is clamped using the roller of eight drift angles of weight frame and is vertically directed
Bar, simple structure, frictional resistance are little, operate steadily, and reduce impact of the frictional force to test accuracy, and position sensor is easy to counterweight
The detection of amount rack position.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is roller generalized section of the present utility model.
In figure, 1. are vertically directed bar, 2. weight frame, 3. roller, 4. position sensor, 5. roller body, and 6. dead axle, 7. inclined
Heart set.
Specific embodiment
Describe this utility model below in conjunction with accompanying drawing and specific embodiment in detail, illustrative examples therein with
And explanation is only used for explaining this utility model, but it is not intended as to restriction of the present utility model.
Embodiment：A kind of drop hammer tester guiding mechanism, including two vertically and be arranged in parallel be vertically directed bar 1, peace
The weight frame 2 of dress weight block, described to be vertically directed bar 1 for cylindrical polished rod, 2 eight drift angles of the weight frame are respectively provided with a rolling
Wheel 3, the pivot center of the roller 3 is vertical with the axis antarafacial for being vertically directed bar 1, and the periphery of the roller 3 is in institute
The outer circumference surface laminating for being vertically directed bar 1 is stated, described being vertically directed on bar 1 is vertically directed 1 length direction of bar interval row along described
Show for detecting the position sensor 4 of 2 position of weight frame.
Clamped using the roller 3 of 2 eight drift angles of weight frame in above-mentioned design and be vertically directed bar 1, simple structure, frictional resistance
It is little, operate steadily, reduce impact of the frictional force to test accuracy, position sensor 4 is easy to the detection to 2 position of weight frame.
Used as the further improvement of the design, the roller 3 includes the dead axle 6 being arranged on the weight frame 2, is arranged on
Roller body 5 on the dead axle 6, is easily installed.
Used as the further improvement of the design, the roller body 5 is bearing, long service life, high precision.
As the further improvement of the design, eccentric bushing 7 on the dead axle 6, is threaded with, the roller body is arranged on
On the eccentric bushing 7, the stability of weight frame 2 is improved in the gap for being conveniently adjusted roller body and being vertically directed between bar 1, is reduced
Energy loss.
As the further improvement of the design, on front side of the weight frame 2 or in the four rolling 3 of rear side, eccentric bushing 7 is provided with,
It is easy to adjust.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in
Other related technical fields, are included in scope of patent protection of the present utility model in the same manner.
