Abstract
The invention discloses a device for testing the service life of a torsional spring. The device for testing the service life of the torsional spring comprises a base, wherein a quick-action cylinder and a slow-action cylinder are arranged at the two ends of the base respectively, the quick-action cylinder is fixedly arranged on the base and is provided with a pivot mechanism which abuts against a clamping hook of a product to be tested, and the slow-action cylinder is fixedly arranged on the base and is provided with a gear mechanism which can overturn an upper cover of the product to be tested. The device can test the service life of the torisional spring fast and conveniently.
Description
Technical field
The present invention relates to a kind of proving installation, be 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 of 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, when upper cover and body cover, the snap fit of upper cover base side portion blocks, when 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, yet have on the market relevant device at present, do not realize the torsion spring test in serviceable life.
Summary of the invention
The object of the invention is to provide a kind of torsion spring proving installation in serviceable life, uses this device, can to torsion spring, test serviceable life quickly and easily.
Technical scheme of the present invention 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.
Advantage of the present invention is:
1. the present invention 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 of gear mechanism is closed, use this device, can be easily to testing the serviceable life of torsion spring;
2. the present invention is simple in structure, easy to use, is applicable to promoting the use of.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the structural representation of the embodiment of the present invention one.
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 6 of product to be measured, 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 6 of described product to be measured.
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.
Device is 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 invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformation or modification that according to the present invention, the Spirit Essence of main technical schemes is done, within all should being encompassed in protection scope of the present invention.
