CN203210224U - Connecting rod clamping mechanism - Google Patents

Abstract

The utility model discloses a connecting rod clamping mechanism, comprising a V-shaped groove clamping platform and a frame which is arranged on the V-shaped groove clamping platform, wherein a clamping rod and a handle are respectively hinged on the frame; the clamping rod is hinged with the handle through a middle rod; an included angle alpha between the middle rod and the handle is 0-5 degrees; and a stop dog is arranged on the clamping rod. By adopting the connecting rod clamping mechanism, a workpiece can be clamped only through a manual force, so that the connecting rod clamping mechanism is convenient and quick to operate and has a strong clamping force.

Description

A kind of link-type clamping mechanism

Technical field

The utility model relates to a kind of clamp mechanism, particularly a kind of link-type clamping mechanism.

Background technology

The clamping of workpiece, cylinder particularly often adopts the both sides, bottom to clamp platform with V-shaped groove and fixes, and the upper end is the method that clamps again of the clamp mechanism by special use again, this clamp mechanism generally is by hydraulic control, clamping force is big, and firm, efficient, precision is high again, but hydraulic system structure complexity, noise is big, and also need pass through the oil pump oil transportation, has consumed certain electric energy.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of clamping force big, only needs the manual link-type clamping mechanism that firmly gets final product clamping work pieces.

For achieving the above object, the technical solution of the utility model is: a kind of link-type clamping mechanism, comprise that V-shaped groove clamps platform and is installed in V-shaped groove clamping platform upper spider, be hinged with clamping bar, handle on the frame respectively, be articulated and connected by intermediate bar between clamping bar and the handle, angle α between intermediate bar and the handle is 0 ° ~ 5 °, and clamping bar is provided with block.

The beneficial effects of the utility model are: only need firmly to get final product clamping work pieces by hand, and convenient and swift, and also clamping force is big.

Description of drawings

Fig. 1 is the structural representation of the utility model when clamping work pieces.

Among the figure: V-shaped groove clamps platform 1, frame 2, clamping bar 3, handle 4, intermediate bar 5, block 6.

The specific embodiment

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.

Embodiment:

As shown in Figure 1, a kind of link-type clamping mechanism, comprise that V-shaped groove clamps platform 1 and is installed in V-shaped groove clamping platform 1 upper spider 2, be hinged with clamping bar 3, handle 4 on the frame 2 respectively, be articulated and connected by intermediate bar 5 between clamping bar 3 and the handle 4, angle α between intermediate bar 5 and the handle 4 is 0 ° ~ 5 °, and clamping bar 3 is provided with block 6.

Operation principle of the present utility model is: frame 2, clamping bar 3, handle 4 and intermediate bar 5 constitute linkage, enforce handle 4, until the dead point of block 6 places to linkage, be that α is 0 °, when handle 4 overlaps with intermediate bar 5, at this moment, workpiece stepped up the power maximum.

Claims (1)

1. link-type clamping mechanism, comprising that V-shaped groove clamps platform (1) and is installed in V-shaped groove clamps frame (2) on the platform (1), it is characterized in that: be hinged with clamping bar (3), handle (4) on the described frame (2) respectively, be articulated and connected by intermediate bar (5) between described clamping bar (3) and the handle (4), angle α between described intermediate bar (5) and the handle (4) is 0 ° ~ 5 °, and described clamping bar (3) is provided with block (6).
