Abstract
The utility model discloses a part clamping mechanism which comprises a working platform, an air cylinder and a plate turning seat, wherein the air cylinder and the plate turning seat are arranged on the working platform; a connecting rod shaft is arranged in an inner hole of the plate turning seat, is connected with the output end of the air cylinder and is driven by the air cylinder to move in the plate turning seat; the other end of the connecting rod shaft is connected with a clamping plate through a curve connection rod, the curve connection rod is fixed on the plate turning seat through a turnover shaft pin to drive the clamping plate to move vertically or rotatably, the curve connection rod is provided with a curved groove with a certain included angle, and the turnover shaft pin is arranged in the curved groove; with the turnover shaft pin as the fixing point, the curve connection rod moves in the different direction but consistent with the curve of the curved groove. The part clamping mechanism retains the overturning form of a pressing head, ensures the vertical clamping of a turning plate to a part, prevents the pressing head from blocking the taking/putting of the part in the moving process and ensures that the surface of the part cannot be scratched in the clamping process.
Description
Technical field
The utility model relates to a kind of part clamp mechanism, especially relates to a kind of clamp mechanism that is used for plastic casing parts such as automobile instrument, oil pump.
Background technology
Having some to resemble automobile instrument, oil pump etc. in automobile zero, parts is the plastic casing part, and in production and testing process, the outer surface of these parts is to need to lay special stress on protecting, and a bit scuffing and impression can not be arranged.For the accuracy of assembling and detecting, shell is accurately positioned and pneumatic pinch often.
General apparatus for production line is to adopt cylinder to drive the lever upset to clamp part, the essential defect of this clamping mode is: because clamping point walks at the head of lever is circular curve, therefore pressure head can have micro displacement at piece surface when touching piece surface and continuing to clamp, and this micro displacement can form scuffing at piece surface, influences the presentation quality of product.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of part clamp mechanism at problems of the prior art, its objective is under the prerequisite that keeps the pressure head flipped form, avoid clamping process that piece surface is produced and scratch, guarantee the presentation quality of part.
The technical solution of the utility model is that this kind part clamp mechanism comprises workbench and is installed in cylinder and turnover panel seat on the workbench, pitman shaft is arranged in the endoporus of turnover panel seat, and pitman shaft is connected with the output of cylinder, cylinder drivening rod axle moves in the turnover panel seat, the other end of described pitman shaft is connected with clamping plate by a connecting rod that can change the direction of motion, and the drive clamping plate is done vertical or rotatablely moved.
The described connecting rod that changes the direction of motion is a curve connecting rod with angle, and the curve connecting rod is fixed on the turnover panel seat by the upset pivot pin.
Be positioned at described curve connecting rod and be provided with the curved groove with angle, the upset pivot pin is positioned at this curved groove, and the curve connecting rod is the motion that fixing point is made the different directions consistent with the curve of curved groove with the upset pivot pin.
The length control of the vertical direction of the curved groove on the described curve connecting rod clamps the distance of part, the flip angle of the distance control clamping plate of incline direction.
Angular range between adjacent two limits of curved groove on the described curve connecting rod is 0 °-180 °.
A kind of part clamp mechanism and using method thereof with said structure have the following advantages:
1, this kind part clamp mechanism had both kept the pressure head flipped form, had guaranteed the vertical clamping of turnover panel to part again, avoided pressure head can hinder picking and placeing of part in the process of motion, guaranteed again simultaneously can not produce the surface of part in the clamping process to scratch.
2, this kind part clamp mechanism adopts the linkage principle, and is simple in structure, take up room for a short time, is applicable to the automation clamping of various parts.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
In Fig. 1,1: cylinder; 2: pitman shaft; 3: the turnover panel seat; 4: the upset pivot pin; 5: the curve connecting rod; 6: clamping plate; 7: workbench.
The specific embodiment
Structure shown in Figure 1 is the structural representation of this kind part clamp mechanism, this clamp mechanism comprises workbench 7 and is installed in cylinder 1 and turnover panel seat 3 on the workbench 7, pitman shaft 2 is arranged in the endoporus of turnover panel seat 3, and pitman shaft 2 is threaded with the output of cylinder 1, cylinder 1 drivening rod axle 2 moves in turnover panel seat 3, and pitman shaft 2 can cooperate mobile at turnover panel seat 3 hole internal clearances; The other end of pitman shaft 2 is connected with clamping plate 6 by a connecting rod that can change the direction of motion, drive clamping plate 6 is done vertical or is rotatablely moved, the connecting rod that changes the direction of motion is a curve connecting rod 5 with angle, and curve connecting rod 5 is fixed on the turnover panel seat 3 by upset pivot pin 4.Be positioned at curve connecting rod 5 and be provided with the curved groove with angle, upset pivot pin 4 is positioned at this curved groove, and curve connecting rod 5 is the motion that fixing point is made the different directions consistent with the curve of curved groove with upset pivot pin 4.The length control of the vertical direction of the curved groove on the curve connecting rod 5 clamps the distance of part, the flip angle of the distance control clamping plate 6 of incline direction.The other end of pitman shaft 2 is connected with curve connecting rod 5 shaft hole pin gaps; The curved groove that upset pivot pin 4 passes curve connecting rod 5 is riveted on the turnover panel seat 3; Curved groove and upset pivot pin 4 matched in clearance; Clamping plate 6 screws are connected in the other end of curve connecting rod 5.Angular range between adjacent two limits of curved groove on the curve connecting rod 5 is 0 °-180 °.
The method of utilizing this kind part clamp mechanism to clamp, unclamp is specially:
1) when cylinder 1 stretches out, curve connecting rod 5 drives clamping plate 6, and under the restriction of upset pivot pin 4, clamped part is unclamped in curved groove motion at first vertically;
2) along inclined direction curved groove motion then, clamping plate 6 produces upset;
3) when cylinder 1 withdrawal, curve connecting rod 5 drives clamping plate 6, and under the restriction of upset pivot pin 4, curved groove motion at first along inclined direction makes clamping plate 6 produce upset;
4) vertically curved groove motion then vertically clamps part.
The curved groove length of adjusting vertical direction on the curve connecting rod 5 can be controlled the distance of vertical clamping part, adjusts the tilt angle of curved groove of direction of curve connecting rod 5, can adjust the flip angle of clamping plate 6.This kind part clamp mechanism had both kept the pressure head flipped form, had guaranteed the vertical clamping of turnover panel to part again, avoided pressure head can hinder picking and placeing of part in the process of motion, guaranteed again simultaneously can not produce the surface of part in the clamping process to scratch.
