Description

Cable hut torsion tester
Technical field
The utility model belongs to the detection field of cable hut, relates to a kind of electronic product detecting housing tolerance torsion situation, especially a kind of cable hut torsion tester.
Background technology
At present, existing housing Verification of resistance to torsional stress equipment is relative with test method original, is made up of easy column, pulley, weight load etc.During test, Shell specimens is placed on the region that can be fixed, is exerted a force to housing from both direction by counterweight, steel cable, pulley, weight load etc.But this mode applicability is not strong, and process of the test wastes time and energy, can not the security of warranty test personnel, can not the accuracy of warranty test.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of design operation is easy, the cable hut torsion tester of safety and precise.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of cable hut torsion tester, it is characterized in that: comprise base, main body frame, crossbeam, slide block, pulley, weight load, pulley, wirerope and lifting jack, base is installed the fixture being used for fixing tested sample, be provided with main body frame above this base, the equal horizontal cross of main body frame front and rear sides corresponding above base is provided with crossbeam; This crossbeam adopts longitudinal adjustment structure of upper and lower guiding, and the two ends being specially the crossbeam of both sides are all mounted on main body frame top, and crossbeam is driven by threaded screw rod and regulates guide rail made inside main body frame to move up and down; Crossbeam is upper and lower two, on these two crossbeams, equal horizontal slip is provided with a slide block, all pulley is installed in the end of crossbeam, this slide block is connected with wirerope and wirerope is walked around pulley and is connected with weight load in the vertical direction, slide block on described upper and lower two crossbeams to connect the direction of wirerope contrary, the counterweight lower end of both sides all supports and is provided with lifting jack, and slide block place is shaped with the graduated scale for measuring.
And described base lower end is provided with multiple rolling bearing, sample is sent into the testing position of specifying in main body frame by the design of drawing and pulling type; Base installs four fixtures by threaded adjustment.
Advantage of the present utility model and good effect are:
1, this testing machine adopts the material such as square steel, steel pipe welded structure, effectively ensure that the intensity of equipment, makes process of the test more safe and reliable.
2, the crossbeam of this testing machine can upper and lowerly regulate, pulley is by the left and right adjustment of elongated slot on crossbeam and the utilization of fixture block place line slideway and slide block, make the scope of application of equipment larger, compared to former equipment can only be used for less and regular shape by the detection of test agent, this equipment can meet the test demand of different size, difformity sample.
3, the operation of this testing machine flexible and convenient more, high-effective and labour-saving, testing crew is reduced to 2 people by 3 original people, and test period foreshortened to about 30 minutes by original 2 ~ 3 hours.
4, crossbeam of the present utility model, pulley all adopt design-adjustable, avoid resolution of force, and force is more accurate, error range within 0.5%, and by the data of mobile scale Measurement accuracy housing distortion value.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the right view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of cable hut torsion tester, comprise base 9, main body frame 1, crossbeam 2, slide block 3, pulley 6, weight load 7, pulley 6, wirerope 5 and lifting jack 8, base is installed the fixture being used for fixing tested sample 4, above this base, main body frame is installed, the crossbeam that the equal horizontal cross of main body frame front and rear sides corresponding above base is provided with;
In order to the cable box sample measuring different size can be suitable for, this crossbeam adopts longitudinal adjustment structure of upper and lower guiding, the longitudinal screw leading screw 10 being all mounted on main body frame top in the middle part of the two ends being specially the crossbeam of both sides is driven by threaded screw rod and regulates, and the guide rail made inside main body frame of crossbeam moves up and down;
In order to lateral adjustments, crossbeam is upper and lower two, on these two crossbeams, equal horizontal slip is provided with a slide block, all pulley is installed in the end of crossbeam, this slide block is connected with wirerope and wirerope is walked around pulley and is connected with weight load 7 in the vertical direction, on described, slide block on lower two crossbeams to connect the direction of wirerope contrary, thus make slide block relative sliding, the weight load of the present embodiment adopts 100kg counterweight, the counterweight lower end of both sides all supports and is provided with lifting jack, slide block can be made to be stuck on the frame of tested sample firmly, reach the object of distortion housing, there is the graduated scale for measuring at slide block place, can measure accurately the deflection of force back casing sample.
For the ease of laying tested sample, base lower end is provided with multiple rolling bearing, sample is sent into the testing position of specifying in main body frame by the design of drawing and pulling type; Base installs four fixtures by threaded adjustment, prevents the movement of sample position in process of the test.
By above-mentioned longitudinal adjustment structure and slide block level adjusting structure, Impact direction can be made to be consistent, to avoid resolution of force, thus ensure stressed accurate.
During test, step is as follows:
(1) tested sample is placed on base, the fixture on adjusting base, sample is fixed;
(2) regulate the height and position of crossbeam according to the height of tested sample, make slide block correspondence can be held in the top bezel locations of sample;
(3) adjusting slider, pulley and weight loaded components, makes slide block, pulley and weight load mutually vertical;
(4) use lifting jack to rise counterweight, regulate wirerope to lock lifting jack after the length be applicable to, and determine that slide block has firmly been stuck on the shell frame of tested sample;
(5) lifting jack is unclamped in both sides simultaneously, falls counterweight, and at this moment the torsion of 1000N is born in test product both sides simultaneously, and starts timing, duration 30s, reads and records the deflection size of tested sample in process of the test;
(6) the lifting jack of both sides rises counterweight simultaneously, then reads and records the frame deformation data of now tested sample, equipment and test specimen is recovered to cause original position after completing measurement.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
