Abstract

The invention discloses a double-fixing clamping mechanism of a machine tool, and belongs to the field of machine tool clamps. The mechanism comprises a sliding rail, an adjusting screw rod, a movable block, a clamping block, a pressing plate, a fixing device and a handle. The upper end of the sliding rail is clamped on a concave edge at the lower end of the movable block, the lower end of the clamping block is pressed on a concave edge at the upper end of the movable block, the adjusting screw rod is meshed with the movable block, the clamping block and the pressing plate are connected through the fixing device, and the pressing plate can move up and down. The double-fixing clamping mechanism solves the problems that when an existing clamping mechanism clamps a workpiece, the clamping mechanism is prone to move axially, radial clamping force is too large, and accordingly the workpiece is damaged, and has the advantages of being simple in structure, reasonable in design and easy to manufacture.

Description

The two fixing and holding mechanisms of lathe
Technical field
The invention belongs to the jig field, more particularly, relate to a kind of two fixing and holding mechanisms for the fixture clamping.
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, play, owing to only being subject to radially chucking power, axially easily occurs in workpiece.If strengthen radially chucking power, axial float can be resolved to a certain extent, but is faced with the possibility of crushing workpiece.Therefore, a kind of clamping device for the workpiece axial restraint of necessary design.
Summary of the invention
The problem of axially easy play, the excessive easily damaged workpiece of radial clamping power during for existing clamping device holding workpiece, the invention provides the two fixing and holding mechanisms of a kind of lathe.
For addressing the above problem, the present invention adopts following technical scheme.
The two fixing and holding mechanisms of a kind of lathe, comprise slide rail, adjusting screw(rod), movable block, clamp, pressing plate, fixture and handle, and the upper end of described slide rail is stuck 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, and pressing plate can fluctuate.
Preferably, described fixture is comprised of a screw and spring; Described screw is connected on clamp through after pressing plate; Described spring housing is connected on screw, between pressing plate and clamp.
Preferably, the top of described handle is rotary handle, and bottom is a screw rod, and screw rod is through screwing in clamp after pressing plate.
Preferably, also be provided with support spring between described pressing plate and clamp.
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 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.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention.
As shown in Figure 1 and Figure 2, the two fixing and holding mechanisms of a kind of lathe, comprise slide rail 1, adjusting screw(rod) 2, movable block 3, clamp 4, pressing plate 5, fixture 6 and handle 7, and the upper end of described slide rail 1 is stuck 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, and pressing plate 5 can fluctuate.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, 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 4.7 one, handle shown in figure is positioned at the place ahead (according to the judgement of Fig. 1 direction) of fixture 6, and one is positioned at the right-hand of fixture 6, and the position between concrete handle 7 and fixture 6 can arbitrarily be adjusted.
In use, first rotate adjusting screw(rod) 2, movable block 3, under the effect of adjusting screw(rod) 2, makes slide rail 1 slide to centre, thereby the clamping of moving and complete of drive clamp 4 is moved; 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.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.
embodiment 1
As shown in Figure 1 and Figure 2, the two fixing and holding mechanisms of a kind of lathe, comprise slide rail 1, adjusting screw(rod) 2, movable block 3, clamp 4, pressing plate 5, fixture 6 and handle 7, and the upper end of described slide rail 1 is stuck 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, and pressing plate 5 can fluctuate.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, 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.
