Abstract

The invention discloses a pressure-controllable pawl type anti-loose clamp which belongs to the field of clamps. The clamp comprises a clamp base, a screw rod, a moving block, a clamping block as well as a gear, an outer ring, a pawl, a screw rod and a scale disc, wherein the screw rod is meshed with the moving block; the gear is assembled on the screw rod through a key; the outer ring is fixedly connected with the clamp base and is provided with a threaded hole and a spring; one end of the pawl is hinged to the outer circle; the other end of the pawl is connected with the spring; the screw is assembled in the threaded hole of the outer ring and is compressed on the pawl; the scale disc is fixed on the screw rod. The clamp solves the problems that a conventional clamp is not reliable to clamp, not easy to control the clamping force and is easy to loosen, and has the advantages of simple structure, reasonable design and easiness in manufacturing.

Description

The locking fixture of pressure controllable type pawl type
Technical field
The invention belongs to fixture field, more particularly, relate to a kind of locking fixture of pressure controllable type pawl type for preventing that piece-holder is loosening.
Background technology
In machine industry, lathe is widely used in processing all kinds of parts, when processing parts, relates to its clamping and positioning problem.Workpiece is adding man-hour, by the clamping of fixture, can be adapted to various machining.But due to the vibration of lathe in process and the effect of cutting force, cause fixture to occur loosening, and then because piece-holder power causes the loosening of workpiece not, reduced machining accuracy, when serious, will cause workpiece to be thrown out of the generation of accident.Need to guarantee that fixture chucking power when clamping work pieces easily controls simultaneously.
Summary of the invention
The clamping that causes for existing fixture is unreliable, chucking power is wayward, easy loosening problem, the invention provides the locking fixture of a kind of pressure controllable type pawl type.
For addressing the above problem, the present invention adopts following technical scheme.
The locking fixture of a kind of pressure controllable type pawl type, comprise clamping fixture seat, screw rod, movable block, clamp, the upper end of clamping fixture seat is pressed on the recessed edge in movable block lower end, clamp lower end is pressed on the recessed edge in movable block upper end, screw rod is meshed with movable block, also comprise gear, outer ring, spring, ratchet, screw, dial, described gear is assemblied on screw rod by key, described outer ring is fixed on clamping fixture seat, and be provided with screwed hole and spring, one end of described ratchet is hinged on outer ring, other end linking springs, described screw is assemblied in the screwed hole of outer ring, and be pressed on ratchet, described dial is fixed on screw rod.
Described spring is extension spring.
Than prior art, beneficial effect of the present invention is:
(1) the present invention utilizes gear and ratchet to realize the locking effect to screw rod, and in the course of the work, the locking to screw rod due to gear and ratchet, has played the locking of screw rod, and then makes fixture can not occur becoming flexible because of the effect of vibration and cutting force.
(2) the present invention is provided with dial on screw rod, can be the in the situation that of clamp fast moving, and assurance clamp in OK range, is unlikely to damage workpiece to the pressure of workpiece; During simultaneously Workpiece clamping for unlike material and size, the reading of dial is made statistical table, convenient while operating in the future as contrasting, thereby increase work efficiency.
(3) the present invention is simple in structure, reasonable in design, is easy to manufacture.
