Description
Technical field
The utility model relates to a kind of anchor clamps of testing rubber pulling strengrth, relates in particular to a kind of anchor clamps that are used for the testing rubber pulling strengrth.
Background technology
At present; Electronic tension tester is when the various tensile strength of material of test, and the used anchor clamps of clamping material only are furnished with circular section bar commonly used and square-section plate grip, and to soft rubber material; Use when using the anchor clamps clamping always; Very smooth and extensibility is very big because of rubber surface, use very big clamping force during clamping, also can make retaining part rubber draw fewer and fewer at the rubber of clip position along with the increase of distortion; Pull out the chuck clamping position to rubber at last, so anchor clamps commonly used can not clamp the elastomeric material with favorable elasticity.
Summary of the invention
The purpose of the utility model has been to provide a kind of anchor clamps that are used for the testing rubber pulling strengrth; These test pulling force anchor clamps overcome existing anchor clamps commonly used can not clamp smooth flexible elastomeric material, causes pulling out the rubber of retaining part the defective of chuck clamping position during stretching.These pulling force anchor clamps adopt compression spring back-pressure test specimen locking mechanism, and initial clamping force is little, along with test power (or distortion) increases; The principle that clamping force increases thereupon clamps the rubber test specimen; Be difficult for skidding, structure, charge and discharge operations are simple and reliable, and test result is accurate.
The utility model realizes that like this it comprises the location
[Word groove, chuck, lever, hand lever, awl rectangle column, spring guide, compression spring is characterized in that the location
[Place two identical chucks in the word groove; The junction of two chucks is respectively equipped with the serrate plane; Two chucks respectively symmetry connect an end of two levers, a be connected through the hinge end of hand lever of the other end of two levers, and the other end of two hand levers is connected on the awl rectangle column through hinge jointly; The top of awl rectangle column connects an end of spring guide, and the other end of spring guide is in the location
[The bottom center of word groove, the connecting rod that is connected through the hinge between the lever of two symmetries is with compression spring on the spring guide of connecting rod below.
The technique effect of the utility model is: these pulling force anchor clamps have been filled up the defective that does not have clamping testing rubber tensile strength of material anchor clamps, elastomeric material that can 0.1 ~ 6 millimeter thickness of clamping; Adopt the characteristics of compression spring back-pressure elastomeric material locking mechanism, only need hand lever 1 and hand lever 2 drawn simultaneously and draw close, can be easily with the elastomeric material clamping with unload, it is little to have more volume, simple in structure, does not crush advantages such as non-slip.

Embodiment
As shown in Figure 1, the chuck left side (1) of anchor clamps upper end and chuck right (4) are installed in the location
[In the word groove (5), can be in the location
[Inwardly or outwards move simultaneously in the word groove (5); The hole of lever 1 (6) upper end is connected with pin with the groove in right (4) stage casing of chuck; The hole of lever 2 (21) upper ends is connected with pin with the groove in (1) stage casing, a chuck left side; The hole of the hole of lever 1 (6) middle-end and connecting rod 1 (7) right-hand member connects to form hinge 1 (9) with pin (8); The hole of the hole of lever 2 (21) middle-ends and connecting rod 1 (7) left end connects to form hinge 2 (23) with pin; The hole of the hole of lever 1 (6) lower end and connecting rod 2 (13) lower ends connects to form hinge 4 (14) with pin; The hole of the hole of lever 2 (21) lower ends and connecting rod 3 (26) lower ends connects to form hinge 5 (27) with pin, and the hole of the hole of connecting rod 3 (26) upper ends and connecting rod 2 (13) upper ends connects to form hinge 3 (12) with pin, with pin hinge 3 (12) is fixed on the awl rectangle column (16); The outer compression spring (11) that puts of the spring guide (10) of awl rectangle column (16) upper end; Guide-localization cover (25) is fixed on the medium position of connecting rod 1 (7), and guide-localization cover (25) can move up and down in spring guide (10), and the screw rod (18) of awl rectangle column (16) lower end is connected with clamp base (19) and is fixing with piecing together jack panel (17); During use; Hand lever 1 (15) and hand lever 2 (28) drawn to the anchor clamps center simultaneously draw close, lever 1 (6) and lever 2 (21) simultaneously downwards the guide-localization cover (25) installed of drivening rods 1 (7) middle part on spring guide (10), move downward compression spring (11) compression, lever 1 (6) and lever 2 (21) drive downwards simultaneously a chuck left side (1) and chuck right (4) downwards and chuck left (1) and the chuck right side (4) locating
[The interior anti-phase motion of word groove (5); 6 millimeters clamping position is located to open in the interface serrate plane (2) of a chuck left side (1) and chuck right (4); Clamp base (19) is provided with the connecting hole (20) that is connected with testing machine, is respectively equipped with Spring Card (22) through pad (24) in hinge 2 and the hinge 1.
The principle of work of the utility model is: testing rubber pulling strengrth anchor clamps are made up of last anchor clamps and lower clamp, and jig Design is identical up and down.During clamping elastomeric material (3); Hand lever 1 and hand lever 2 are drawn by the anchor clamps center simultaneously; The lower end of lever 1 and lever 2 downward levers 1 simultaneously and lever 2 is to the anchor clamps central motion; (hinge 1 is the fulcrum of lever 1 and lever 2 with hinge 2), the upper end of lever 1 and lever 2 just drives a chuck left side and is locating on the chuck right side
[To two movement outside, 6 millimeters clamping position is just opened at place, serrate plane in the word groove, and the guide-localization at connecting rod 1 middle part is enclosed within on the spring guide and moves downward simultaneously, and compression spring is compressed.After elastomeric material installs hand lever 1 and hand lever 2 are unclamped; The bounce of compression spring is upspring connecting rod 1; Upwards the lower end of lever 1 and lever 2 is to two movement outside simultaneously with lever 2 for lever 1, and the upper end of (hinge 1 and hinge 2 are the fulcrum of lever 1 and lever 2) lever 1 and lever 2 just drives a chuck left side and is locating on the chuck right side
[The word groove is interior to the anchor clamps central motion; Thereby elastomeric material is compressed, will promote connecting rod 1 upwards as long as elastomeric material is out of shape the bounce of (attenuation) compression spring to some extent, just open the lower end of lever 1 and lever 2; And draw in the upper end of lever 1 and lever 2; Because of hinge 1 and hinge 2 are installed in the position of the upper end 1/3rd of lever 1 and lever 2, according to lever principle, the clamping force between a chuck left side and the chuck right side will increase thereupon.The elastic force of compression spring has multiple, can change as required.
