Abstract
The invention discloses a pressure measurable limiting type looseness-preventing clamp and belongs to the field of clamps. The pressure measurable limiting type looseness-preventing clamp comprises a clamp base, a screw rod, a moving block and a clamping block. The screw rod is meshed with the moving block. The pressure measurable limiting type looseness-preventing clamp further comprises a ratchet wheel, running pulleys, levers, a spring, a bolt and a pressure sensor. The ratchet wheel is assembled to the screw rod through keys, the two ends of the spring are connected to the levers on the two sides of the ratchet wheel, the bolt penetrates through polished holes reserved in the levers, and the pressure sensor is arranged on the clamping face of the clamping block. The pressure measurable limiting type looseness-preventing clamp solves the problems that an existing clamp is unreliable in clamping, cannot control clamping force easily and is easy to loosen, and has the advantages of being simple in structure, reasonable in design, and easy to manufacture.
Description
Technical field
The invention belongs to fixture field, more particularly, relate to a kind of locking fixture of pressure measurable type restraint-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 measurable type restraint-type.
For addressing the above problem, the present invention adopts following technical scheme.
The locking fixture of a kind of pressure measurable type restraint-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 ratchet, roller, lever, spring, bolt, pressure sensor, described ratchet is assemblied on screw rod by key, the quantity of described lever is 2, divide and be located at ratchet both sides, and be all hinged on clamping fixture seat, and away from one end of clamping fixture seat, unthreaded hole is set at lever, described roller is connected through the hinge on lever, the two ends of described spring are connected on the lever of ratchet both sides, described bolt is through the reserved unthreaded hole of lever, 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 ratchet and roller to realize the locking effect to screw rod, and in the course of the work, the locking to screw rod due to ratchet and roller, 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 adopts two symmetrical rollers, has eliminated radial load screw rod being caused because of locking effect, has improved the service life of fixture.
(3) the present invention is provided with pressure sensor on clamp, 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; 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.
(4) the present invention is simple in structure, reasonable in design, is easy to manufacture.
