Abstract
The invention provides a four-bar clamping mechanism which comprises a support block, and a fourth connection block, a third connection block and a first connection block sequentially connected with the support block in the vertical direction. The support block is connected with the fourth connection block by bolts; the fourth connection block is movably connected with the third connection block; the third connection block is movably connected with the first connection block; the third connection block is fixedly connected with the second connection block; and the second connection block is fixedly connected with a handle. The four-bar clamping mechanism has the benefits that the location function and the clamping function are realized simultaneously, plates different in apertures can be located and clamped, the design period is shortened, the number of non-standard processing parts is reduced, the processing cost is low, the manufacturing period is reduced, the welding spatial position for an operator is increased, an air cylinder is protected against pollution of welding slag, etc.
Description
Technical field
The invention relates to the anchor clamps in a kind of automobile making, especially relates to a kind of four link-type clamping mechanism.
Background technology
In existing technology, weld jig is subordinate to nonstandard industry, particularly auto manufacturing and need to requires to carry out independent Design and manufacture according to vehicle, and every anchor clamps often have the uniqueness of self.All can use various clamp mechanism on many weld jigs in the weld car equipment workshop, a lot of utilizations of clamp mechanism commonly used manually push away pincers, the location automobile metal plate work.Cost is very high, and the manufacturing cycle is longer.Design a kind of novel four connecting rod large scale clamp mechanism during present urgent problem, can realize simultaneously the function locating and clamp, the plate location that can adapt to different apertures clamps, design cycle reduces, nonstandard workpiece reduces, and processing cost is lower, and the manufacturing cycle shortens, increase the operator and weld the locus, can also make cylinder prevent many advantages such as welding slag pollution.
Summary of the invention
The problem that the invention will solve provide a kind of simple in structure, reasonable in design, effect significantly, use easy four link-type clamping mechanism.
For solving the problems of the technologies described above, the technical scheme that the invention is adopted is: a kind of four link-type clamping mechanism, comprise back-up block and be connected vertically connect and described back-up block on the 4th contiguous block, the 3rd contiguous block, the first contiguous block; Described back-up block is connected with the 4th contiguous block bolt; The 4th contiguous block and the 3rd contiguous block are flexibly connected; The 3rd contiguous block and the first contiguous block are flexibly connected; Described the 3rd contiguous block is fixedly connected with the second contiguous block; Described the second contiguous block is fixedly connected with handle.
Further, described the 3rd contiguous block and described the first contiguous block are bolted.
Further, described the 3rd contiguous block is connected by bearing pin with described the first contiguous block.
Further, tell the 4th contiguous block and described the 3rd contiguous block is bolted.
Further, tell the 4th contiguous block and be connected the 3rd contiguous block and connect by bearing pin.
Advantage and good effect that the invention has are: owing to adopting technique scheme, the invention comprises back-up block, the 4th contiguous block, the 3rd contiguous block and first contiguous block of vertical connection successively; Described the 3rd contiguous block is fixedly connected with the second contiguous block; Described the second contiguous block is fixedly connected with handle.Can realize simultaneously the function locating and clamp, the plate location that can adapt to different apertures clamps, and the design cycle reduces, nonstandard workpiece reduces, and processing cost is lower, and the manufacturing cycle shortens, increase the operator and weld the locus, can also make cylinder prevent the advantages such as welding slag pollution.
Description of drawings
Fig. 1 is the structural representation of the invention;
Fig. 2 is the cutaway view of the invention.
Among the figure:
1, back-up block 2, the first turning point 3, the 3rd contiguous block
4, the 3rd turning point 5, the first contiguous block 6, the second turning point
7, the second contiguous block 8, handle 9, the 4th contiguous block
The specific embodiment
As shown in Figure 1, 2, the invention provides a kind of four link-type clamping mechanism, comprise back-up block 1 be connected vertically connect with described back-up block 1 on the 4th contiguous block 9, the 3rd contiguous block 3, the first contiguous block 5; Described back-up block 1 is connected with the 4th contiguous block 9 bolts; The 4th contiguous block 9 and the 3rd contiguous block 3 are flexibly connected; The 3rd contiguous block 3 and the first contiguous block 5 are flexibly connected; Described the 3rd contiguous block 3 is fixedly connected with the second contiguous block 7; Described the second contiguous block 7 is fixedly connected with handle 8.Described the 3rd contiguous block 3 is bolted with described the first contiguous block 5 or bearing pin is connected.Institute's the 4th contiguous block 9 of telling be connected that the 3rd contiguous block 3 is bolted or bearing pin connects.
The course of work of this example: when driving handle 8, handle 8 drives the second contiguous block 7 and the 3rd contiguous block 3 travels forward around the first turning point 2.The 3rd contiguous block 4 drives the first contiguous block 5 and travels forward around the second turning point 6.This moment is for manually stretching out state.When lifting handle 8, handle 8 drives the second contiguous block 6, the three contiguous blocks 3, moves backward around the first turning point 2.The 3rd contiguous block 4 companies of drive first connect piece 5 and move backward around the second turning point 6.Be open mode this moment.
An above embodiment to the invention has been described in detail, but described content only is the preferred embodiment of the invention, can not be considered to for the practical range that limits the invention.All equalizations of doing according to the invention application range change and improve etc., all should still belong within the patent covering scope of the invention.
