Description
Technical Field
The utility model relates to a positioning mechanism, especially a simple and easy scissors formula location supporting mechanism.
Background
When positioning or processing parts, a tool clamp is needed. The traditional tool clamp is generally suitable for parts with normal sizes, and for some parts with small sizes, positioning and clamping cannot be carried out, or the positioning effect is poor. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, the action is smooth, reliable, and occupation space is little, is applicable to the tight supporting mechanism of small part positioning clip.
The technical solution of the utility model is that: the utility model provides a simple and easy scissors formula location supporting mechanism which characterized in that: the mechanism comprises a box body 1, a piston rod 3 is connected to the box body 1 in a sliding mode through a self-lubricating bearing 2, a pin shaft 4 is arranged at the bottom end of the piston rod 3, a support frame 5 is further arranged at the bottom of the box body 1, a swing arm 7 is rotatably supported on the support frame 5 through a transfer shaft 6, the two swing arms 7 are symmetrically arranged, a positioning bolt 8 is connected to the bottom of the swing arm 7, an adjusting pad 9 is further arranged between the positioning bolt 8 and the swing arm 7, a groove is formed in the swing arm 7 and consists of a first groove 10 and a second groove 11 which are mutually communicated, an included angle of 130 degrees is formed between the central axes of the first groove 10 and the second groove 11, and the pin shaft 4 is movably connected in the groove in a penetrating mode.
Compared with the prior art, the utility model, have following advantage:
this kind of structural style's simple and easy scissors formula location supporting mechanism, to the problem that traditional anchor clamps exist in the use, design one kind and utilize special-shaped slot drive swing arm action structure, this kind of mechanism creatively utilizes special-shaped slot and sets up the round pin axle cooperation action on the swing arm, and the drive swing arm is the swing action in the minizone. The device has the advantages of smooth and reliable action, no occupation of too much space, simple manufacturing process and low manufacturing cost, so that the device has various advantages and is particularly suitable for popularization and application in the field.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: a simple scissor type positioning and supporting mechanism comprises a box body 1, a piston rod 3 is connected to the box body 1 in a sliding mode through a self-lubricating bearing 2, a pin shaft 4 is arranged at the bottom end of the piston rod 3, a supporting frame 5 is further arranged at the bottom of the box body 1, a swing arm 7 is rotatably supported on the supporting frame 5 through a transfer shaft 6, the swing arms 7 are arranged symmetrically, a positioning bolt 8 is connected to the bottom of the swing arm 7, an adjusting pad 9 is further arranged between the positioning bolt 8 and the swing arm 7, a groove is formed in the swing arm 7 and consists of a first groove 10 and a second groove 11 which are mutually communicated, an included angle of 130 degrees is formed between the central axes of the first groove 10 and the second groove 11, and the pin shaft 4 is movably connected in the groove in a penetrating mode.
The simple scissors type positioning and supporting mechanism with the structure form has the working process as follows: firstly, the box body of the supporting mechanism is moved, the positioning bolts 8 at the bottom ends of the two swing arms 7 are inserted into the positioning holes of the workpiece, then the piston rod 3 is driven to move, the piston rod 3 can drive the pin shaft 4 to move longitudinally, because the hinge shaft 6 is fixed, and the pin shaft 4 is movably connected in the special-shaped groove in a penetrating way, the pin shaft 4 can drive the two swing arms 7 to swing by taking the hinge shaft 6 as a shaft relative to the groove,
the piston rod 3 drives the pin shaft 4 to move downwards, the bottom ends of the two swing arms 7 expand, and the inner hole of the workpiece is positioned and supported from the inner side; the piston rod 3 drives the pin shaft 4 to move upwards, the bottom ends of the two swing arms 7 are folded, and the workpiece recovers the degree of freedom.
