Abstract
The utility model discloses a washer anti-rotation fixture and a special washer seat thereof. The washer anti-rotation fixture comprises the washer seat and is characterized in that a center hole and a circular groove used for holding a washer are arranged on the washer seat, positioning holes communicated with the circular groove are arranged on the circumference surface of the washer seat, and fixing bolts are arranged inside the positioning holes. The washer is arranged inside the circular groove, fixed by the fixing bolts and sleeved into a tested bolt before a torsion test is carried out. Since the contact area between the washer seat and a holding groove of a fixing fixture of the tested bolt is much larger than that between the washer and the holding groove, frictional resistance produced during twisting is much higher. As the washer cannot rotate during the torsion test, effect of the torsion test can be guaranteed. Further, the washer anti-rotation fixture is simple in structure and convenient in operation.
Description
Technical field
The utility model relates to the torsional moment test auxiliary, relates in particular to fastener torque test auxiliary, specifically a kind of stationary fixture that is used for preventing the packing ring rotation of tested bolt auxiliary connection.
Background technology
When the bolt auxiliary connection carries out torsional moment test, carry out according to the following steps: with reference to Fig. 1, earlier the head of bolt 1 is passed the medium pore of sensor 2 and bolt anchor clamps 3 from the outside, again packing ring 4 and nut 5 are enclosed within bolt head from the inboard successively, and place in the storage tank 7 of bolt anchor clamps 3; After screwing nut, with the jacket casing of torsional moment test on nut 5.Open the torsional moment test power supply, sleeve slowly screws nut and the bolt auxiliary connection is applied moment of torsion gradually and twists off until bolt.In this process, sensor outputs to control circuit with detected moment to carry out measurements and calculations and exports net result.According to the test standard requirement, must not rotate at the process of the test middle washer, otherwise that this test is considered as is invalid.Yet the situation of rotating at actual tests process middle washer takes place often, and some packing ring rotates and is difficult for finding, thereby influences rationality, accuracy, the stability of bolt torque test findings.In order to solve the problem that packing ring rotates, each testing agency and manufacturer have used the whole bag of tricks to guarantee that packing ring does not rotate, such as:
1, placing sand paper below packing ring increases friction force between packing ring and the anchor clamps.
2, the chucking surface to contacting with packing ring increases surfaceness.
3, remove packing ring part material method, make its profile become non-circle contour, again packing ring is put in the anchor clamps identical with gasket profile.
Yet in real work, we find the 1st, 2 two kind of method can only reduce the probability that packing ring rotates, and can not guarantee fully that packing ring maintains static.Though the 3rd kind of method can guarantee that packing ring rotates, and has destroyed the integrality of sample.
Summary of the invention
To be solved in the utility model is the problems referred to above that prior art exists, and aims to provide a kind ofly can either guarantee that packing ring maintains static, and can guarantee the anchor clamps of sample integrality again, is used for the torsional moment test of bolt auxiliary connection.
For addressing the above problem, the utility model is by the following technical solutions: the anti-anchor clamps of turning round of packing ring, comprise gasket seat, it is characterized in that described gasket seat is provided with center pit and places the circular groove that packing ring is used, on periphery, be provided with the pilot hole of being used to lead to described circular groove, be provided with set bolt in the described pilot hole.
Packing ring of the present utility model is anti-turns round anchor clamps, and packing ring is placed in the circular groove, is inserted in tested bolt again after fixing with set bolt and carries out torsional moment test.Because gasket seat is much bigger with the contact area of tested bolt anchor clamps storage tank contact area more direct than packing ring itself and storage tank, the frictional resistance that produces when therefore reversing is also much bigger, so can not rotate at the process of the test middle washer, can guarantee that test effectively.And this clamp structure is simple, and is easy to operate.
As further improvement of the utility model, described pilot hole is no less than 3, and evenly distributes on periphery.Preferred 3 of the quantity of described pilot hole can guarantee that packing ring reliably is positioned at center position.
Further improve as of the present utility model, described set bolt is a hexagon socket head cap screw again.Because hex bolts is stressed evenly, and is not easy to wear, therefore use is received a mandate longer.
Further improve as of the present utility model, the external diameter of described gasket seat is slightly less than the storage tank internal diameter of tested bolt anchor clamps, to guarantee to have enough frictional resistance between the two, does not influence whole installation and test simultaneously again.
The utility model also will provide a kind of anti-gasket seat of turning round anchor clamps of packing ring that is used for, and comprises gasket seat, it is characterized in that described gasket seat is provided with center pit and places the circular groove that packing ring is used, and is provided with the pilot hole of being used to lead to described circular groove on periphery.

Embodiment
With reference to Fig. 2,3, the anti-anchor clamps of turning round of packing ring of the present utility model, comprise gasket seat 6, described gasket seat 6 is provided with center pit 8 and places the circular groove 9 that packing ring is used, on periphery, evenly be provided with 3 radial location holes 10 of being used to lead to, be provided with fixedly hex bolts 11 in the described pilot hole 10 with described circular groove.The external diameter of described gasket seat 6 is slightly less than storage tank 7 internal diameters of tested bolt anchor clamps 3.
With reference to Fig. 4,5, packing ring 4 is placed in the circular groove 9 of gasket seat 6, fixedly hex bolts 11 screws and gets final product retaining washer 6.
With reference to Fig. 6, the installation process of tested sample is as follows before the torsional moment test:
Earlier the head of bolt 1 is passed the medium pore of sensor 2 and bolt anchor clamps 3 from the outside, the utility model anchor clamps 12 that packing ring 4 will be housed again are enclosed within bolt head from the inboard, and place in the storage tank 7 of bolt anchor clamps 3; After screwing on nut 5, with the jacket casing of torsional moment test on nut 5.Structure after the installation as shown in Figure 7.
What should be understood that is: the foregoing description is just to explanation of the present utility model, rather than to restriction of the present utility model, any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection domain of the present utility model.
