Abstract
The invention relates to a cotton fiber clamping device. The cotton fiber clamping device comprises a body (1), a fixed clamping block (9) fixed on the body (1), a swinging block (2) hinged on the body (1) through a pin shaft (13), and a following clamping block (7) fixedly connected with a swinging end of the swinging block (2), the clamping device is characterized in that an air flue (14) and a cylinder (3) for driving the swinging block (2) to swing are arranged in the body (1), the cylinder (3) is fixedly connected with the body through an air inlet bolt (6), and a reset spring (15) is arranged between the fixed clamping block (9) and the following clamping block (7). Through the adoption of above technical scheme, the miniaturization requirement of the cotton fiber clamping device and the requirements of being aesthetic in appearance, compact in structure and adjustable in clamping force are effectively realized, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to a kind of fixture, particularly relate to a kind of cotton fiber clamping device.
Background technology
Carry out the performance test of cotton fiber in testing laboratory of textile mills, ultimate fibre tester need be applied and measure its fracture strength and length growth rate.Critical piece chuck in tester divides upper grip and lower chuck.Upper grip and sensor are connected as fixed chuck; When after upper and lower chuck respectively clamped fibers, lower chuck to be driven by leading screw by motor and at the uniform velocity moves downward.Display after the fracture strength of fiber and length growth rate are calculated by computer for analysis.
Some chuck adopts electrical clip compact form, promotes jaw by electric pushrod by leverage, and then clamping cotton fiber.The major defect of such version is that physical dimension is large, and grip force size is difficult to regulate, and have impact on clamping quality, also have impact on instrument outward appearance simultaneously.Have adopt manpower clamp form by eccentric wheel, upper and lower clamp divides secondary to clamp, but due to cotton fiber short, manual operation is very inconvenient, and there are the problems referred to above equally.For overcoming above shortcoming, a kind of small-sized attractive in appearance, fiber clamping device that grip force is adjustable, easy to operate need be designed.
Summary of the invention
The object of this invention is to provide the cotton fiber clamping device that a kind of compact conformation clamping force is adjustable, have more flexibility.
The technical scheme realizing above-mentioned purpose is: a kind of cotton fiber clamping device, comprise body, the fixing fixture block be fixed on body, by the swinging block of hinge on body, be fixedly connected at the servo-actuated fixture block of swinging block swinging end, the cylinder being provided with air flue in described body and driving swinging block to swing, cylinder is fixedly connected by air inlet screw and body, fixes and is provided with resetting means between fixture block and servo-actuated fixture block.
Further, the piston component of described cylinder comprises piston throw-out collar and is sleeved on O-ring seal 4 on piston throw-out collar.
Further, described resetting means comprises back-moving spring, set screw and support pin; Set screw thread connection is in the inside of body and be close to back-moving spring, for regulating the elastic force of back-moving spring; Support pin thread connection at body, for adjustment screw.
Further, described piston throw-out collar is provided with sharp boss.
Further, also pasted soft pad above servo-actuated fixture block, fixing fixture block is made up of Rubber materials.。
After adopting technique scheme, there is following beneficial effect:
(1) adopt the combination of built-in air cylinder and integrated form gas circuit, fully meet small form factor requirements and appearance and modeling, rational in infrastructure compact.
(2) vapour-pressure type chuck can make clamping evenly and there is flexibility, and grip force is adjustable.
(3) easy to operate, low cost of manufacture.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
As shown in Fig. 1 ~ 2: a kind of cotton fiber clamping device, comprise body 1, the fixing fixture block 9 be fixed on body 1, the swinging block 2 be hinged on by bearing pin 13 on body 1, be fixedly connected at the servo-actuated fixture block 7 of swinging block 2 swinging end, the cylinder 3 being provided with air flue 14 in described body 1 and driving swinging block 2 to swing, cylinder 3 is fixedly connected by air inlet screw 6 and body 1, fixes and is provided with resetting means 15 between fixture block 9 and servo-actuated fixture block 7.
Further, for reducing manufacturing cost of the present invention, realize miniaturization, aesthetic appeal moulding, rational in infrastructure compact, the piston component of described cylinder 3 comprises piston throw-out collar 5 and is sleeved on O-ring seal 4 on piston throw-out collar 5.
Further, adjustable in order to realize grip force, described resetting means 15 comprises back-moving spring 12, set screw 11 and support pin 10; Set screw 11 thread connection is in the inside of body 1 and be close to back-moving spring 12, for regulating the elastic force of back-moving spring 12; Support pin 10 thread connection at body 1, for adjustment screw 11.
Further, in order to ensure clamping effect, described piston throw-out collar 5 is provided with sharp boss.
Further, in order to ensure clamping effect, servo-actuated fixture block 7 has also pasted soft pad 8 above, and fixing fixture block 9 is made up of Rubber materials.
Principle of work of the present invention is as follows: in body 1, is connected the cylinder 3 be built in body 1, be furnished with piston throw-out collar 5 and O-ring seal 4 in cylinder 3 by air inlet screw 6.Swinging block 2 is connected to servo-actuated fixture block 7 with screw, and servo-actuated fixture block 7 has also pasted soft pad 8 above.Body 1 is connected to the fixing fixture block 9 processed by Rubber materials.
During work, the air flue 14 in body 1 enters pressurized air, and by the groove on air inlet screw 6 and hole, promote piston throw-out collar 5 and move right, the sharp boss on piston throw-out collar 5 promotes swinging block 2 again and swings to the right around bearing pin 13, thus clamping is as the fiber of figure position.
After pressurized air is withdrawn from, swinging block 2 is resetted by back-moving spring 12, turns set screw 11, the reset force of adjustable back-moving spring 12, and support pin 10 is used for locking set screw 11.
