Abstract
The utility model relates to a clamping mechanism, in particular to a clamping mechanism with a stretchy pressing plate. The clamping mechanism with the stretchy pressing plate comprises a base and the pressing plate with a clamping head and further comprises a hook-shaped cam, a clamping screw, a compression spring, a supporting seat provided with a sliding groove and a bolt with the lower end connected with the base. The middle of the pressing plate is provided with a long-bar-shaped hole for the bolt to insert, and the end, away from the clamping head, of the pressing plate is provided with a threaded hole. The bottom of the end, away from the clamping head, of the pressing plate is provided with a hinge plate. The upper end of the bolt is provided with a pressing nut, and the compression spring is arranged on the bolt between the pressing plate and the base in a sleeved mode. The supporting seat is arranged on the base at the end away from the clamping head, and one end of the hook-shaped cam is hinged to the end, away from the clamping head, of the pressing plate. The other end of the cam is connected with the clamping screw in a sliding mode. The clamping screw can be screwed into the threaded hole. The bottom of the cam is located in the sliding groove of the supporting seat. The pressing plate can be pushed so that a workpiece to be clamped can be placed more easily, and clamping efficiency can be improved.
Description
Technical field
The utility model relates to a kind of clamp mechanism, is specifically related to the telescopic clamp mechanism of a kind of pressing plate.
Background technology
In machine tooling, conventionally after need to using clamp mechanism that workpiece is fixing, carry out again follow-up processing, so clamp mechanism is widely used in workpiece manufacture field, and existing clamp mechanism shortcoming is: the pressing plate of holding workpiece can only be made holding action, and pressing plate holding action is less, therefore the gap of pressing plate clamping head and workpiece to be clamped is less, so that workpiece to be clamped is put into the clip position of appointment is just more time-consuming.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of pressing plate telescopic clamp mechanism, and the pressing plate of this clamp mechanism can promote, so it is easier to place workpiece to be clamped, thereby can improve the efficiency of clamping.
For achieving the above object, the technical solution of the utility model is: the telescopic clamp mechanism of pressing plate, comprise pedestal and the pressing plate with clamping head, wherein, also be provided with hook-type cam, pinching screw, Compress Spring, be provided with the bolt that the supporting seat of chute is connected with pedestal with lower end, described pressing plate middle part is provided with the strip hole that described bolt inserts, and pressing plate clamping head far away one end is provided with screwed hole, and bottom, pressing plate clamping head far away one end is provided with articulated slab; Described bolt upper end is provided with clamp nut, and described Compress Spring is sheathed on the bolt between pressing plate and pedestal; Described supporting seat is located on the pedestal of clamping head far away one end, cam one end of described hook-type and pressing plate clamping head far away one end are hinged, the other end and described pinching screw are slidably connected, and described pinching screw can be screwed in screwed hole, and described cam bottom is positioned at the chute of supporting seat.
While adopting technique scheme, workpiece to be clamped is positioned on pedestal, towards pressing plate clamping head direction Level Promoting pressing plate, pressing plate is moved horizontally to workpiece to be clamped top, the cam of hook-type moves in the inter-sync of supporting seat chute, housing screw is screwed out to screwed hole, the eccentric side of cam of hook-type goes to supporting seat and contacts, cam pin joint and articulated slab are elevated, also raise thereupon pressing plate clamping head far away one end, the compressed spring in position at pressing plate middle part and clamp nut restriction, thus pressing plate clamping head one end bottom, thus clamping work pieces.Pressing plate of the present utility model can Level Promoting, so it is easier to place workpiece to be clamped, thereby can improve the efficiency clamping.
Further, described housing screw is provided with cursor, when housing screw being screwed into or back-outing screwed hole, needs larger torque, and cursor has effectively increased the arm of force, so more laborsaving when housing screw being screwed into or back-outing screwed hole.
Further, described Compress Spring two ends are provided with spring base, when Compress Spring direct effect is used on pressing plate and pedestal, easily cause improper distortion, and the power on pressing plate of putting on is inhomogeneous, and spring base can not only reduce the improper distortion of Compress Spring, and the power on pressing plate of putting on is even.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the telescopic clamp mechanism embodiment of the utility model pressing plate.
Detailed description of the invention
As shown in Figure 1, the telescopic clamp mechanism of a kind of pressing plate 2, comprise pedestal 1 and the pressing plate 2 with clamping head, wherein, also be provided with hook-type cam 6, pinching screw 7, Compress Spring 4, be provided with the bolt 3 that the supporting seat 9 of chute is connected with pedestal 1 with lower end, pressing plate 2 middle parts are provided with the strip hole that bolt 3 inserts, and pressing plate 2 clamping head far away one end are provided with screwed hole 21, and pressing plate 2 bottoms, clamping head far away one end are provided with articulated slab 22; Bolt 3 upper ends are provided with clamp nut 5, and Compress Spring 4 is sheathed on the bolt 3 between pressing plate 2 and pedestal 1; Supporting seat 9 is located on the pedestal 1 of clamping head far away one end, cam 6 one end of hook-type and pressing plate 2 clamping head far away one end are hinged, the other end and pinching screw 7 are slidably connected, pinching screw 7 can be screwed in screwed hole 21, cam 6 bottoms are positioned at the chute of supporting seat 9, in the present embodiment, housing screw 7 is provided with cursor, and Compress Spring 4 two ends are provided with spring base.
Specific works flow process:
As shown in Figure 1, be illustrated as pressing plate 2 clamping heads in clamp position.Workpiece to be clamped 10 is positioned on pedestal 1, Level Promoting pressing plate 2 left, pressing plate 2 is moved horizontally to workpiece to be clamped 10 tops, the cam 6 of hook-type is moved to the left in supporting seat 9 chute inter-syncs, housing screw 7 is screwed out screwed hole 21 by rotation pivoted arm 8, the eccentric side of cam 6 of hook-type goes to supporting seat 9 and contacts, cam 6 hinged ends and articulated slab 22 are elevated, also raise thereupon pressing plate 2 clamping head far away one end, the compressed spring 4 in position and the clamp nut 5 at pressing plate 2 middle parts limit, so pressing plate 2 clamping head one end bottoms, thereby clamping work pieces 10.Housing screw 7 is screwed in screwed hole 21 by rotation pivoted arm 8, the nearly heart one side of cam 6 of hook-type goes to supporting seat 9 and contacts, cam 6 hinged ends and articulated slab 22 move down, pressing plate 2 clamping head far away one end also move down thereupon, the compressed spring 4 in position and the clamp nut 5 at pressing plate 2 middle parts limit, so pressing plate is put on 2 clamping head one end, thereby unclamps workpiece 10.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
