Abstract
An upper pressing mechanism of a composite clamp relates to the technical field of clamps and is characterized by comprising an oil cylinder, an oil cylinder fixing frame, an upper press plate and a movable block. The oil cylinder is arranged on the oil cylinder fixing frame, a piston rod of the oil cylinder is located on the lower portion, the upper press plate is connected with the lower end of the piston rod, and the movable block is located under the upper press plate. The upper pressing mechanism is characterized in that floating combination spherical washers are arranged at the connection position of the upper press plate and the piston rod of the oil cylinder. The combination spherical washers comprise a spherical groove washer and a spherical face washer. The upper pressing mechanism is simple and reasonable in structure, convenient to use and low in manufacture cost.
Description
Technical field:
The present invention relates to clamp technology field, specifically a kind of upper hold-down mechanism of composite fixture.
Background technology:
People's common combinations fixture solves long problem of Special Clamps Design manufacturing cycle, and built-up jig is divided into three major types: groove is built-up jig, and dowel-pin modular fixture is controlled in conjunction with built-up jig.A kind of fixture of using with cascaded surface workpiece of producing, because clamping area on processed workpiece has ladder, size disunity, while using the fixture of traditional fixed structure setting to press from both sides required processing work, needs to arrange comparatively complicated clamping area like this, and can only be for clamping a certain fixing workpiece, when the slightly different workpiece of production size, be just difficult to use, this mode not only making of fixture own is comparatively complicated, cost is high, and uses inconvenient.
Summary of the invention:
It is a kind of simple and reasonable, easy to use that technical problem to be solved by this invention is to provide, the upper hold-down mechanism of the composite fixture of low cost of manufacture.
The technical problem solving adopts following technical scheme:
A kind of upper hold-down mechanism of composite fixture, it is characterized in that: comprise oil cylinder, oil cylinder fixed mount, top board and movable block, described oil cylinder is arranged on oil cylinder fixed mount, the piston rod of oil cylinder is positioned at bottom, described top board is connected with the lower end of piston rod, described movable block is positioned at the below of top board, it is characterized in that: the piston rod junction of described top board and oil cylinder is provided with unsteady combinatorial sphere packing ring, and described combinatorial sphere packing ring comprises ball groove face packing ring and spherical packing ring.
The junction of described oil cylinder and oil cylinder fixed mount is provided with gland.
Described gland is provided with semi-cyclic linkage with the corner that oil cylinder is combined with oil cylinder fixed mount.
In tradition processing, because clamping area on processed workpiece has ladder, size disunity, so the present invention adopts spherical combination mat, can float top board and carries out workpiece pressing, has so just solved the skimble-scamble cascaded surface of surface of the work size and has clamped.
The invention has the beneficial effects as follows: the present invention is simple and reasonable, easy to use, low cost of manufacture.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of upper hold-down mechanism of composite fixture, comprise oil cylinder 1, oil cylinder fixed mount 2, top board 3 and movable block 4, oil cylinder 1 is arranged on oil cylinder fixed mount 2, the piston rod of oil cylinder 1 is positioned at bottom, and top board 3 is connected with the lower end of piston rod, and movable block 4 is positioned at the below of top board 3, top board 3 is provided with unsteady combinatorial sphere packing ring 5 with the piston rod junction of oil cylinder 1, and combinatorial sphere packing ring 5 comprises ball groove face packing ring 51 and spherical packing ring 52.Oil cylinder 1 is provided with gland 6 with the junction of oil cylinder fixed mount 2.Gland 6 is provided with semi-cyclic linkage 7 with oil cylinder 1 and the corner of oil cylinder fixed mount 2 combinations.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
