Abstract
The invention discloses an anti-twisting washer clamp and a special washer seat thereof. The clamp comprises a washer seat and is characterized in that the washer seat is provided with a central hole and a circular groove for arranging a washer and provided with positioning holes in communication with the circular groove on the periphery, and each positioning hole is internally provided with a fixed bolt. In the anti-twisting washer clamp, the washer is arranged in the circular groove, fixed with the fixed bolt and sleeved in a tested bolt for a torque test. A contact area between the washer seat and an accommodating groove for the fixed clamp of the tested bolt is larger than a contact area between the washer and the accommodating groove so that friction resistance generated by twisting is also greater, the washer can not rotate in the test process to ensure the effective test. Moreover, the clamp is simple in structure and convenient to operate.
Description
Technical field
The present invention relates to torsional moment test and use auxiliary, relate in particular to fastener torque test and use 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; Screw behind the nut, with the jacket casing of torsional moment test on nut 5.Open the torsional moment test power supply, slowly screw nut and the bolt auxiliary connection is applied moment of torsion gradually twist off of sleeve 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 regarded 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 is fixed.Though the 3rd kind of method can guarantee that packing ring rotates, and has destroyed the integrality of sample.
Summary of the invention
The present invention will solve is the problems referred to above that prior art exists, and aims to provide a kind ofly can either guarantee that packing ring is fixed, 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 present invention adopts following technical scheme: 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 said circular groove, be provided with set bolt in the described pilot hole.
Packing ring of the present invention 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 present invention, described pilot hole is no less than 3, and on periphery, evenly distributes.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 invention, 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 invention, 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 present invention 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 said circular groove on periphery.

Embodiment
With reference to Fig. 2,3; Packing ring of the present invention is anti-turns round anchor clamps, comprises gasket seat 6, and 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 said 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 is screwed and is got final product retaining washer 6.
With reference to Fig. 6, the installation process of tested sample is following 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 anchor clamps of the present invention 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 is as shown in Figure 7.
What should be understood that is: the foregoing description is just to explanation of the present invention, rather than limitation of the present invention, and any innovation and creation that do not exceed in the connotation scope of the present invention all fall within protection scope of the present invention.
