Abstract
The utility model provides an elongation test device when steel cable and steel cable cover atress comprises chuck, pressure head, wire rope, lock nut, wire rope cover, wire rope cover locking dish, adjustable bracket, test bench on the pulling force machine, because the connected mode that adopts pulling force machine and pressure head, pressure head and wire rope is to the power of exerting 98N and 490N of wire rope and wire rope cover accuracy, the convenient elongation of measuring. Adjustable bracket is according to being surveyed wire rope 400 -600mm and being surveyed the arbitrary height -adjusting of length that wire rope overlaps 200 -300mm. It is convenient to measure the location like this, and convenient operation improves test speed and frequency to alleviate intensity of labour good reliability simultaneously.
Description
Technical field
The utility model relates to bicycle and electric bicycle field.
Background technology
Bicycle electric bicycle is the walking-replacing tools conventional when going on a journey of people, because riding light, flexible, laborsaving and liking very by people.Bicycle electric bicycle must have good quality and security performance, for ensureing its quality and using safely and effectively, promulgate related standards, in related standards, define performance requirement and the detection experiment method of various bicycle electric bicycle and various parts.
Electric bicycle be according to QB/T1895-1993 " People's Republic of China's light industry standard " bicycle steel cable and steel rope sleeve stressed time the elongation requirement of testing 5.5 design.Specify by standard: 400-600mm steel cable and 200-300mm steel rope sleeve are fixed on test unit, first apply 98N, after 1min, apply 490N, to measure when amount of movement is less than 98N 0.6% of rope capacity and 1% sum of steel wire loop length.Otherwise the elongation of wire rope and steel wire loop is defective.
Current known steel cable and steel rope sleeve stressed time elongation test unit structure bulky, complicated operation, manufacturability is poor, use is inconvenient, and cost is high, manufactures difficulty.
Summary of the invention
Technical problem to be solved in the utility model is, generator, overcome existing steel cable and steel rope sleeve stressed time elongation test unit device not enough, simplify structure and the processing technology of fixture simultaneously, reduce costs, improve the precision measured.
In order to solve the problems of the technologies described above, the scheme that the utility model adopts is: steel cable and steel rope sleeve stressed time elongation test unit, be made up of puller system ended collet, pressure head, wire rope, set nut, steel wire loop, steel wire loop locking plate, adjustable support; Described puller system ended collet is connected with pressure head; Described pressure head is connected with wire rope; Described steel wire penetrating adjustable support is connected with set nut; Described set nut is connected with steel wire loop; Adjustable support described in described steel wire loop is connected with steel wire loop locking plate is connected with testing table.
The beneficial effects of the utility model are, owing to adopting the connected mode of puller system and pressure head, pressure head and wire rope, can apply the power of 98N and 490N accurately, measure elongation easily to wire rope and steel wire loop.Adjustable support is according to tested wire rope 400-600mm, and the length of tested steel wire loop 200-300mm, regulates arbitrarily height.Such measurement and positioning is convenient, easy to operate, improves test speed and frequency, thus the while of reducing labor intensity, reliability is strong.
Accompanying drawing explanation
Fig. 1 be a kind of steel cable and steel rope sleeve stressed time elongation test unit front view.
In the drawings:
1. puller system ended collet, 2 pressure heads, 3 wire rope, 4 set nuts, 5 steel wire loops, 6 steel wire loop locking plates, 7 adjustable supports, 8 testing tables.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
As seen from Figure 1, a kind of steel cable and steel rope sleeve stressed time elongation test unit, be made up of puller system ended collet 1 pressure head 2, wire rope 3, set nut 4, steel wire loop 5, steel wire loop locking plate 6, adjustable support 7; Described puller system ended collet 1 is connected with pressure head 2; Described pressure head 2 is connected with wire rope 3; Described wire rope 3 is connected with set nut 4 through adjustable support 7; Described set nut 4 is connected with steel wire loop 5; Described steel wire loop 5 is connected with steel wire loop locking plate 6; Described adjustable support 7 is connected with testing table 8.
Puller system ended collet 1 and pressure head 2 are fixed.Adjust adjustable support 7 height, each several part screw of fastening adjustable support 7.Steel wire loop 5 is connected with steel wire loop locking plate 6.Wire rope 3 upper end is connected with pressure head 2.By wire rope 3 through locking after adjustable support 7, steel wire loop 5, steel wire loop locking plate 6, then set nut 4 is locked.Open puller system and first apply 98N, after 1min, apply 490N, measure 0.6% and steel wire loop 5 1% sum of length of wire rope 3 length when amount of movement is less than 98N.Otherwise the elongation of wire rope and steel wire loop is defective.
