Abstract
The present invention relates to a pair of movable jaw type clamping heads for a portable power-driven pulling machine, which is a clamping part of equipment for detecting and testing the tensile strength, the stretching strength, the tearing toughness and the elongation rate of materials and welding members thereof. The present invention is characterized in that bearing frames (11) and (7) are arranged in a casing (1), and a screw rod (9) is supported between the two bearing frames (11); a jaw clamping head B is sheathed on the screw rod (9); a jaw clamping head A is sheathed in the other set of supporting mechanism and can be moved among an extremely left position (6), a middle position (4) and an extremely left position (2); a motor and a speed reducer (5) are also arranged in the casing (1), wherein the screw rod (9) is driven by the motor through the speed reducer to slowly rotate, which enables the jaw clamping head B sheathed on the screw rod (9) to inch to left from an extremely left position (2) until a test piece is damaged, and a damage index is read out on a control and digital display device (3). The present invention enables the length of a pulling machine body to be shortened, and has the advantages of low cost and convenient carrying.
Description
Technical field
The present invention designs a kind of a pair of movably jaw chuck that is used for the portable electric puller system, belongs to mechanical field.
Background technology
Detect the employed equipment of test at building-site, can be small and exquisite as much as possible for ease of carrying hope, the stroke of the jaw formula chuck of fixed test test exemplar is long as much as possible, cost is low as much as possible.The jaw formula chuck of existing puller system fixed test test exemplar, be generally one be fix, another is movably.The patent No. is that the clamping device of 01234101.1 " a kind of tension tester " is rectilinear, and following clamping head is had only last clamping head to be driven by leading screw by transfer table and moved up and down by bolt.The patent No. is being characterized as of 93239028.5 " double stroke universal vice ": 1, jaw has the big characteristics of opening degree; 2, " two-pass characteristics "; 3, " fireballing characteristics ".Yet two covers are by interchangeable caliper seat and be screwed jaw thereon, the assembly that voussoir forms is fixed on interior moving caliper, the outer moving caliper with socket head cap screw respectively.Leading screw is to be connected on the outer moving caliper by thrust ring and screw retention, in screw mandrel screws in by being threaded again in the moving caliper, so the opening degree of jaw not can greater than, even can not equal the length of leading screw.On the stroke, under the drive of leading screw in moving caliper, outer moving caliper do the reverse sync motion, two jaws also are the reverse sync motions, can not embody the length that is doubled to strengthen stretching by double stroke.On fireballing characteristics, according to physical fundamental formular w (power)=F (power) * V (speed), under the identical situation of pulling force, after speed improves, the also corresponding raising of power of motor, and then must increase volume, weight and the cost of motor.
Summary of the invention
Technical matters to be solved by this invention is to overcome stroke weak point in the above-mentioned testing machine, and the testing machine volume is big, the problem that cost is high.
For solving the problems of the technologies described above, the present invention designs a pair of jaw chuck that is used for the portable electric tension tester, and each jaw chuck can both be distinguished self-movement.
Technical essential of the present invention is in the portable electric puller system that is made of shell 1, jaw chuck A, B, control and digital display unit 3, motor and speed reduction unit 5, bearing bracket stand 7, leading screw 9, bearing bracket stand 11, bearing bracket stand 11 and bearing bracket stand 7 are housed in the shell 1, supporting leading screw 9 between two bearing bracket stands 11,7, jaw chuck B is enclosed within on the leading screw 9, and leading screw 9 is connected with kinematic trains such as motor and speed reduction units 5; Jaw chuck A is enclosed within the another set of supporting mechanism, and jaw chuck A can progressively move to 4 positions until moving to 2 positions from 6 positions under the positioning element effect.
The invention has the advantages that two jaw chucks all are transportable, can make full use of the space of drive motor like this, significantly reduced the length and the weight of puller system, promptly under the situation of identical puller system length, the stroke L of jaw formula chuck can increase by 50%～70%; That is to say that the length of puller system leading screw can reduce 70%～50% under the situation of the jaw formula jaw travel of equal length.Because usually the manufacturing cost of leading screw is with its length and precision exponent function relation, so as the contraction in length of leading screw 9 one by one of mechanically operated critical component in the tension tester, the cost of tension tester will reduce greatly.
Description of drawings
Fig. 1 is a pair of movably jaw chuck structure figure that is used for the portable electric puller system.
Shell 1, jaw chuck A (ultra-Right position) 2, control and digital display unit 3, jaw chuck A (centre position) 4, motor and speed reduction unit 5, jaw chuck A (ultra-Left position) 6, bearing bracket stand 7, jaw chuck B (ultra-Right position) 8, leading screw 9, jaw chuck B (ultra-Left position) 10, bearing bracket stand 11 among the figure.
Embodiment
The utility model is designed a kind of a pair of removable jaw chuck that is used for the portable electric tension tester.Elaborate embodiments of the present invention below in conjunction with Fig. 1.
Portable electric tension tester in the present embodiment mainly is made up of shell 1, jaw chuck A, B, control and numeric display unit 3, motor and speed reduction unit 5, bearing bracket stand 7, leading screw 9, bearing bracket stand 11, bearing bracket stand 7,11 is fixed on the casing, two bearing bracket stands are supporting leading screw 9, and jaw chuck B is sleeved on the leading screw; Control and numeric display unit 3 and motor and speed reduction unit 5 all are fixed on the casing; Jaw chuck A is contained on the another set of supporting mechanism, and can be separately fixed at 6,4,2 places, position.
At first jaw chuck A is fixed on 6 places, position during measurement, one head-clamp of testpieces is held on the jaw chuck A, the other end is clamped on the jaw chuck B, drive leading screw 9 by motor 5, jaw chuck B is moved to the left and elongates testpieces, destroy until testpieces, read every data by control and digital display unit 3.If jaw chuck B moves on to 10 places by 8 places, testpieces does not also destroy, testpieces can be taken off, A is fixed on 4 places with the jaw chuck, repeats aforesaid operations, if testpieces does not also destroy, then jaw chuck A can be fixed on 2 places, repeat aforesaid operations again, destroy until testpieces, by the every data that read in the numeric display unit 3 before and after destroying, thereby measure the tension intensity of testpieces.More than each parts be fixed in the casing 1.Because position-movable, the adjustment of jaw chuck A, then the leading screw 9 of frame between bearing bracket stand 7,11 can be shorter than the leading screw in the general puller system, thus can reduce the cost of leading screw, thus reduce the cost of portable electric tension tester.
This device can be used in the portable electric tension tester.
Claims (1)
