Abstract

The utility model relates to a clamping device, in particular to a fast clamping mechanism with a cam. The fast clamping mechanism with the cam comprises a base, a pressing plate with a clamping head, the cam, a compression spring, a supporting table and a bolt with the lower end connected with the base. The bolt is arranged in the middle of the pressing plate in a sleeved mode, and a pressing nut is arranged at the upper end of the bolt. The compression spring is arranged on a screw rod between the pressing plate and the base in a sleeved mode. The supporting table is arranged at one end, far away from the clamping head, of the base. The cam is hinged to one end, far away from the clamping head, of the pressing plate and abuts against the upper surface of the supporting table. When the fast clamping mechanism with the cam is used for clamping work-pieces, the cam is automatically locked, force does not need to be exerted on the force exertion end continuously, and therefore the processing efficiency is improved.

Description

Cam quick clamping mechanism
Technical field
The utility model relates to a kind of clamp mechanism, is specifically related to a kind of cam quick clamping mechanism.
Background technology
In machine tooling, after conventionally need to using clamp mechanism that workpiece is fixing, then carry out follow-up processing, so clamp mechanism is widely used in workpiece manufacture field, and existing clamp mechanism shortcoming is while being holding workpiece, force side need to continue the application of force, so cause working (machining) efficiency lower.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of cam quick clamping mechanism, after this clamp mechanism clamping work pieces, cam self-locking, and without continue the application of force in force side, so improved working (machining) efficiency.
For achieving the above object, the technical solution of the utility model is: cam quick clamping mechanism, comprise pedestal and the pressing plate with clamping head, wherein, also be provided with the bolt that cam, Compress Spring, brace table and lower end are connected with pedestal, the middle part of described pressing plate and described bolt empty set, described bolt upper end is provided with clamp nut, sheathed described Compress Spring on screw rod between pressing plate and pedestal, described brace table is located on the pedestal of clamping head far away one end, described cam and pressing plate clamping head far away one end is hinged, and cam and brace table upper surface offset.
While adopting technique scheme, workpiece is positioned on the pedestal under pressing plate clamping head, rotating cam, cam contacts side radius with brace table increases, cam pin joint rises on position, be with on dynamic pressure plate clamping head far away one end simultaneously and rise, and pressing plate middle part is subject to the restriction of clamp nut, so pressing plate clamping head one end bottom, by piece-holder.The utility model pressing plate clamping head is after Workpiece clamping, cam self-locking, and pressing plate is in holding workpiece state, so when pressing plate holding workpiece, without the lasting application of force, improve working (machining) efficiency.
Further, described cam is provided with handle, thereby pulls handle rotating cam, has increased the arm of force that cam rotates, and rotating cam is more laborsaving.
Further, described cam handle one side far away is nearly heart side, and handle is vertically upward time, cam is in unclamping pressing plate state, and when handle goes to level, cam is in clamping platen state, from vertically pulling handle to level, the gravity of handle can be used as the power applying, so more laborsaving.
Accompanying drawing explanation
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 utility model cam quick clamping mechanism embodiment.
The specific embodiment
As shown in Figure 1, a kind of cam quick clamping mechanism, comprise pedestal 1 and the pressing plate 2 with clamping head, wherein, also be provided with cam 4, Compress Spring 5, the bolt 3 that brace table 6 is connected with pedestal 1 with lower end, the middle part of described pressing plate 2 and described bolt 3 empty sets, described bolt 3 upper ends are provided with clamp nut 7, sheathed described Compress Spring 5 on screw rod between pressing plate 2 and pedestal 1, described brace table 6 is located on the pedestal 1 of clamping head far away one end, described cam 4 is hinged with pressing plate 2 clamping head far away one end, cam 4 offsets with brace table 6 upper surfaces, in the present embodiment, described cam 4 is provided with handle 8, and cam 4 handle 8 one sides far away are nearly heart side.
Specific works flow process:
As shown in Figure 1, be illustrated as pressing plate 2 and unclamp workpiece 9 states.Workpiece 9 is positioned on the pedestal 1 under pressing plate 2 clamping heads, pull counterclockwise handle 8, cam 4 also rotates counterclockwise around pin joint, cam 4 contacts side radius with brace table 6 increases, and cam rises on 4 pin joint positions, is with on dynamic pressure plate 2 clamping head far away one end simultaneously and rises, and pressing plate 2 middle parts are subject to the restriction of clamp nut 7, so pressing plate 2 clamping head one end bottoms, clamp workpiece 9, now Compress Spring 5 is compressed; While removing the power putting on handle 8, cam 4 self-lockings, the clamping head of pressing plate 2 is all the time in clamp position.While pulling handle 8 clockwise, cam 4 clockwise rotates around pin joint, cam 4 reduces with the radius that brace table 6 contacts a side, cam 4 pin joint positions decline, be with on dynamic pressure plate 2 clamping head far away one end simultaneously and fall, Compress Spring 5 upwards promotes pressing plate 2, puts and workpiece 9 is unclamped on clamping head one end of pressing plate 2.
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.

Claims (3)
