Abstract
The utility model discloses a torsion spring service life tester comprising a pedestal; two ends of the pedestal are respectively provided with a fast motion cylinder and a slow motion cylinder; the fast motion cylinder is fixedly arranged on the pedestal and provided with a pivot mechanism abutting against a buckle of a tested product; the slow motion cylinder is fixedly arranged on the pedestal and provided with a gear mechanism capable of turning an upper cover of the tested product. The torsion spring service life tester can fast and conveniently test the service life of the torsion spring.
Description
Technical field
The utility model relates to a kind of proving installation, is specifically related to a kind of torsion spring proving installation in serviceable life.
Background technology
At present, torsion spring is widely used in the fields such as automobile, chemical industry, grinding tool, usability and the quality of product under the quality of torsion spring performance directly affects.The performance of torsion spring is mainly determined by following parameters: the material of the diameter of torsion spring steel wire diameter, torsion spring, the pitch of torsion spring, torsion spring etc.Torsion spring, in the process using, need to bear random load power, and the pulsating stress of experience several times changes ultimate failure.
Product to be measured comprises the body of a product, on body, be provided with a upper cover, between upper cover and body, have a torsion spring, in the time that upper cover and body cover, the snap fit of upper cover base side portion blocks, in the time that snap fit is opened, torsion spring can drive upper cover to open, and as can be seen here, torsion spring seems most important for the usability of product to be measured, thereby be very necessary for the test in serviceable life of torsion spring, realize the torsion spring test in serviceable life but do not have on the market relevant device at present.
Summary of the invention
The utility model object is to provide a kind of torsion spring proving installation in serviceable life, uses this device, can test serviceable life torsion spring quickly and easily.
The technical solution of the utility model is: a kind of torsion spring proving installation in serviceable life, comprise pedestal, described pedestal two ends are respectively equipped with fast dynamic air cylinder and slow motion cylinder, described fast dynamic air cylinder is fixedly installed on described pedestal and is provided with the hinge mechanism that can offset with the snap fit of product to be measured, is fixedly installed on described pedestal and is provided with the gear mechanism of the upper cover of turning product to be measured with described slow motion cylinder.
Further technical scheme, described hinge mechanism comprises the trunnion mount being fixed on described pedestal, be hinged with pivot member with described trunnion mount, the cylinder axis of described pivot member one end and described fast dynamic air cylinder is hinged, and the other end is that free end can offset with the snap fit of described product to be measured.
Further technical scheme, described gear mechanism comprises the tooth bar being connected with the cylinder axis of slow motion cylinder, above described tooth bar, be fixed with can with described tooth bar meshed gears, the swingle of affixed turning product upper cover to be measured inside described gear.
The utility model has the advantages that:
1. the utility model is by arranging respectively fast dynamic air cylinder and slow motion cylinder at pedestal two ends, fast dynamic air cylinder connects the hinge mechanism offseting with product snap fit to be measured, slow motion cylinder connects turning product upper cover gear mechanism to be measured, hinge mechanism can press down snap fit upper cover is opened, the rotatable upper cover closure of gear mechanism, use this device, can be easily to testing the serviceable life of torsion spring;
2. the utility model is simple in structure, easy to use, is applicable to promoting the use of.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the structural representation of the utility model embodiment mono-.
Wherein: 1, pedestal; 2, fast dynamic air cylinder; 3, slow motion cylinder; 4, trunnion mount; 5, pivot member; 6, snap fit; 7, tooth bar; 8, gear; 9, swingle; 10, upper cover.
Embodiment
Embodiment mono-: shown in Figure 1, a kind of torsion spring proving installation in serviceable life, comprise pedestal 1, described pedestal 1 two ends are respectively equipped with fast dynamic air cylinder 2 and slow motion cylinder 3, described fast dynamic air cylinder 2 is fixedly installed on described pedestal 1 and is provided with the hinge mechanism that can offset with the snap fit of product to be measured 6, and described slow motion cylinder 3 is fixedly installed on described pedestal 1 and is provided with the gear mechanism of the upper cover 10 of turning product to be measured.
Above-mentioned hinge mechanism comprises the trunnion mount 4 being fixed on described pedestal 1, is hinged with pivot member 5 with described trunnion mount 4, and the cylinder axis of described pivot member 5 one end and described fast dynamic air cylinder 2 is hinged, and the other end is that free end can offset with the snap fit of described product to be measured 6.
Above-mentioned gear mechanism comprises the tooth bar 7 being connected with the cylinder axis of slow motion cylinder 3, above described tooth bar 7, be fixed with can with described tooth bar meshed gears 8, the swingle 9 of the described gear 8 affixed turning product upper covers 10 to be measured in inner side.
Install in use: first the cylinder axis of snap-action cylinder shrinks, and makes the free end of pivot member depress the snap fit of product to be measured, and upper cover is opened; Then the cylinder axis of snap-action cylinder advances, and snap fit is resetted; The cylinder axis of slow motion cylinder stretches out, and tooth bar is moved to base interior direction, and gear is by rack drives and then rotation, driven rotary bar rotation simultaneously, and then upper cover is slowly overturn until blocked by snap fit, and then repeat action above, carry out the life test of torsion spring.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations doing according to the Spirit Essence of the utility model main technical schemes or modification, within all should being encompassed in protection domain of the present utility model.
