Abstract
The invention discloses a pressure measurable pawl-type locking clamp, and belongs to the field of clamps. The pressure measurable pawl-type locking clamp comprises a clamp holder, a screw rod, a moving block, and a clamping block, and also comprises a gear, an outer ring, a spring, a pawl, a screw, and a pressure sensor, wherein the screw rod is meshed with the moving block, and the gear is arranged on the screw rod through a key; the outer ring is fixedly connected onto the clamp holder, and is provided with a threaded hole and the spring, and one end of the pawl is hinged onto the outer ring; the other end of the pawl is connected with the spring, and the screw is arranged in the threaded hole of the outer ring and is pressed on the pawl; the pressure sensor is arranged on a clamping surface of the clamping block. The pressure measurable pawl-type locking clamp provided by the invention solves the problems that the clamping is unreliable, the clamping force is uneasy to control, and the loosening is easy in the prior art, and has the advantages of simple structure, reasonable design, and easiness in manufacture.
Description
Technical field
The invention belongs to fixture field, more particularly, relate to a kind of locking fixture of pressure measurable 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, in the time of 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 ensure that fixture chucking power in the time of 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 measurable type pawl type.
For addressing the above problem, the present invention adopts following technical scheme.
The locking fixture of a kind of pressure measurable 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, pressure sensor, 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 pressure sensor is arranged on the clamping area of clamp.
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 pressure sensor on clamp, can be the in the situation that of clamp fast moving, and guarantee clamp in OK range, is unlikely to damage workpiece to the pressure of workpiece; Pressure during simultaneously Workpiece clamping for unlike material and size 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.
