Description

Adjustable dead weight formula clamp

Technical Field

The utility model belongs to the technical field of the machine-building, concretely relates to adjustable dead weight formula clamp.

Background

The rapid development of the industrialization process, the large-scale popularization of the assembly line work, and the application of the clamp in the mechanical manufacturing technical field plays a considerable role. In the prior art, the clamp mostly needs to provide power for clamping independently or adjust the clamp one by one to clamp; moreover, most of the clamps only aim at the same type or the same type of articles, and are rarely suitable for production lines with multiple specifications, so that clamps with different types are frequently required to be replaced, and time and labor are wasted while excessive funds are consumed in the process; in addition, the clamp structure is more and more complex, parts in the complex mechanism are easy to damage, and the service life of the clamp is greatly shortened.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an adjustable dead weight formula clamp.

An adjustable dead weight type clamp comprises a clamping plate and a long bolt; the clamping plates are L-shaped clamping plates which are paired with each other, the two clamping plates are hinged with each other, each clamping plate comprises a pressed end and a clamping end, the pressed ends extend upwards in an inclined mode from a hinged point in a free state, and the clamping ends extend outwards in an inclined mode; the long bolt is arranged at the top of the clamping end and used for adjusting the opening range of the clamp.

Preferably, the clamp further comprises a support, the support comprises a vertical edge and a horizontal edge which are perpendicular to each other, and the vertical edge is provided with a hinge hole for installing a hinge shaft of the clamping plate.

Preferably, the clamp further comprises a nut, and the nut is mounted on the long bolt and used for locking the long bolt and assisting in adjusting the opening range of the clamp.

Preferably, every splint all include the sideboard and be fixed in the intermediate lamella between two sideboard around, the intermediate lamella is located on the exposed core, the stay bolt is fixed in on the intermediate lamella.

Preferably, the side plates of the two clamping plates are arranged in a mutually nested manner at the front and back of the compression end.

The utility model has the advantages that: the L-shaped clamping plates are hinged with each other, the clamping ends of the L-shaped clamping plates extend outwards in an inclined mode, and the pressing ends of the L-shaped clamping plates extend upwards in an inclined mode from the hinged shaft, so that when an article is placed at the pressing ends of the clamps, the pressing ends are pressed downwards due to the dead weight of the article, the clamping ends of the clamping plates are driven to clamp the article, and clamping driving force does not need to be provided additionally; the long bolt is arranged at the clamping end of the clamping plate, the opening range of the clamp can be adjusted according to the size of an object to be clamped, and the clamp is widely applied to objects of various specifications. The utility model discloses simplify the device structure when reaching actual practical function, simple to use's part reaches the optimal effect, prolongs the life of clamp simultaneously, reduces the spare part damaged condition that the clamp that the structure is complicated easily caused.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

FIG. 1 is a schematic view of the present invention;

labeled in the figure as: 1. a support;

2. a splint; 21. a side plate; 22. a middle plate; 23. a clamping end; 24. a compression end;

3. a long bolt; 4. a nut; 5. and (4) hinging the shaft.

Detailed Description

As shown in fig. 1, the adjustable deadweight clamp comprises a bracket 1, a clamping plate 2, a long bolt 3, a nut 4 and a hinge shaft 5. The bracket 1 comprises a horizontal edge and a vertical edge which are perpendicular to each other, a hinge shaft 5 is arranged on the vertical edge, and the hinge shaft 5 is used for hinging the clamping plate 2; wherein the splint 2 is formed by mutually hinging two L-shaped splint plates which are paired with each other; in the free state, i.e. before clamping the article, the short sides of the clamping plate 2 extend obliquely upwards from the hinge axis 5 position, forming a compression end 24 at the extended end; the long sides of the clamping plate 2 extend obliquely upwards and outwards, and a clamping end 23 is formed at the end of the extension.

Each clamping plate 2 comprises a pair of side plates 21 and a pair of middle plates 22, wherein the two side plates 21 are oppositely arranged, and two middle plates 22 which are oppositely arranged are arranged in the long edge part of the clamping plate, so that the long bolt 3 is penetratingly arranged at the upper ends of the two middle plates 22; the short edge parts of the sideboard 21 are internally kept hollow, which is convenient for the front and back staggered mutual nesting and installation of the paired splints 2. The nut 4 is arranged on the long bolt 3 in a matching way.

The utility model discloses when using: the fixing position of the long bolt 3 can be adjusted according to the size of an article to be clamped in actual needs, then the article is placed on the pressed end 24 of the clamping plate 2, the pressed end 24 is pressed down by the self weight of the article, the clamping plate 2 rotates around the hinge shaft 5, the two clamping ends 23 of the clamping plate 2 are close to each other and clamp the article, and finally the position of the long bolt 3 is selected and adjusted according to actual needs and the nut 4 is used for locking the position. When the clamped state of the article is maintained, the clamping plate 2 is kept in the clamped state for a long time due to the gravity of the article which is downward.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
