Background technology
In machine industry, lathe is widely used in processing all kinds of parts, is adding man-hour, need to carry out the machining such as cylindrical, end face, screw thread and axial cut-out as locating surface with end face or endoporus.But add man-hour for inside workpiece, workpiece is owing to only being subject to radially chucking power, play axially easily occurs, if strengthen radially chucking power, axial float can be resolved to a certain extent, but be faced with the possibility of crushing workpiece, need to, under the prerequisite that does not affect crudy, reduce to chucking power minimum simultaneously as far as possible.
Summary of the invention
Axially easily play, the radially excessive easily damaged workpiece of chucking power, the uppity problem of chucking power during for existing fixture holding workpiece, the invention provides the two stationary fixtures of a kind of pressure measurable type.
For addressing the above problem, the present invention adopts following technical scheme.
The two stationary fixtures of a kind of pressure measurable type, comprise clamping fixture seat, slide rail, adjusting screw(rod), movable block, clamp, pressing plate, fixture, handle, sensors A, sensor B, the lower end of described slide rail is connected with clamping fixture seat, the upper end of slide rail is pressed on the recessed edge in movable block lower end, described clamp lower end is pressed on the recessed edge in upper end of movable block, described adjusting screw(rod) is meshed with movable block, described clamp is connected by fixture with pressing plate, pressing plate can fluctuate, described handle is threaded connection and is assemblied in pressing plate, be provided with sensors A on described clamp, be provided with sensor B on described pressing plate.
Preferably, described fixture (6) is comprised of a screw and spring; Described screw is connected on clamp (4) through after pressing plate (5); Described spring housing is connected on screw, is positioned between pressing plate (5) and clamp (4).
Preferably, the top of described handle (7) is rotary handle, and bottom is a screw rod, and screw rod is through screwing in clamp (4) after pressing plate (5).
Preferably, also be provided with support spring between described pressing plate (5) and clamp (4).
Preferably, described sensors A and sensor B are pressure sensor.
Than prior art, beneficial effect of the present invention is:
(1) the present invention is provided with pressing plate, and it can prevent that workpiece from adding the play of man-hour on axially.
(2) after the present invention arranges pressing plate, can reduce to a certain extent radially chucking power, reduce the damage to surface of the work.
(3) the present invention is provided with sensor on clamp and pressing plate, can be when clamp moves, guarantee clamp to the pressure of workpiece in OK range, be unlikely to damage workpiece, also can prevent that when axial location pressure is excessive; The Workpiece clamping of pressure during simultaneously to(for) unlike material and size is made statistical table, convenient while operating in the future as a comparison, thereby increase work efficiency.
(4) the present invention is simple in structure, reasonable in design, is easy to manufacture.
The accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention.
In figure: 1-slide rail, 2-adjusting screw(rod), 3-movable block, 4-clamp, 5-pressing plate, 6-fixture, 7-handle, 8-sensors A, 9-sensor B.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention.
As Fig. 1, shown in Fig. 2, the two stationary fixtures of pressure measurable type comprise clamping fixture seat, slide rail 1, adjusting screw(rod) 2, movable block 3, clamp 4, pressing plate 5, fixture 6, handle 7, sensors A 8, sensor B9, the lower end of described slide rail 1 is connected with clamping fixture seat, the upper end of slide rail 1 is pressed on the movable block 3 recessed edge in lower end, described clamp 4 lower ends are pressed on the recessed edge in upper end of movable block 3, described adjusting screw(rod) 2 is meshed with movable block 3, described clamp 4 is connected by fixture 6 with pressing plate 5, pressing plate 5 can fluctuate, described handle 7 is threaded connection and is assemblied in pressing plate 5, be provided with sensors A 8 on described clamp 4, be provided with sensor B9 on described pressing plate 5.Fixture 6 is comprised of a screw and spring; Described screw is connected on clamp 4 through after pressing plate 5; Described spring housing is connected on screw, between pressing plate 5 and clamp 4.The top of described handle 7 is rotary handle, and bottom is a screw rod, and screw rod is through in the rear screw-in clamp 4 of pressing plate 5.Also be provided with support spring between described pressing plate 5 and clamp 4.Sensors A 8 and sensor B9 are pressure sensor
In use, first rotate adjusting screw(rod) 2, movable block 3 is under the effect of adjusting screw(rod) 2, make slide rail 1 slide to centre, thereby the clamping of moving and complete that drives clamp 4 is moved, pressure when now sensors A 8 inductions clamp, and pass to display screen, guarantee the chucking power of workpiece is unlikely to excessive; Adjust again pressing plate 5, make the seal face alignment pieces of pressing plate 5, complete the clamping action of pressing plate 5 by rotary handle 7, the pressure of now sensor B9 induction pressing plate 5, and pass to display screen, guarantee the pressure of workpiece is unlikely to excessive.Clamp 4 clamping work pieces sides now, pressing plate 5 and the effect of workpiece end face, complete location.Otherwise counter-rotating adjusting screw(rod) 2 and handle 7 can loosen workpiece.
