Abstract
The utility model provides a stationary clamping device for tongs, which comprises an upper arm, an upper die, a lower die and a support, wherein the lower die is fixed on the support; one end of the upper arm is connected with the support through a pin shaft; and the upper die is fixed at the inner side of the upper arm. The stationary clamping device also comprises a driving oil cylinder; a cylinder lever connecting lug on the driving oil cylinder is connected with the upper arm through the pin shaft; and a cylinder bottom connecting lug is connected with the support through the pin shaft. The stationary clamping device has the beneficial effects of wide clamping diameter range, high fastening pressure, simple installation and high technical requirements and manufacturing cost and is simple to maintain.
Description
Technical field
The utility model relates to a kind of instrument that fixes to clamp, particularly a kind of clamp fixed clamp device.
Background technology
Prior art has dual mode when fixedly cylinder with large diameter or pipe: a kind of is the clamp that adopts chain-type, and a kind of is to adopt the heavy wool cylinder synchronous clamping device.The shortcoming of above prior art is: the chain-type clamp, and the diameter range of clamping article is little, and for manually fastening, fastening pressure is little; The heavy wool cylinder synchronous clamping device relates to the synchronous problem of heavy wool cylinder, and device is complicated, specification requirement and manufacturing cost height, maintenance difficult.
Summary of the invention
The purpose of this utility model is to overcome problems of the prior art, and a kind of clamp fixed clamp device is provided.
The technical solution of the utility model is as follows:
A kind of clamp comprises upper arm, last dental lamina, following dental lamina, support with the fixed clamp device, following dental lamina is fixed on the support, one end of upper arm is connected with support by bearing pin, last dental lamina is fixed on the upper arm inboard, comprise that also drives an oil cylinder, cylinder bar on the driving oil cylinder connects ear and is connected with upper arm by bearing pin, and cylinder bottom connects ear and is connected with support by bearing pin.
The clamping face of last dental lamina and following dental lamina is cancave cambered surface or is the concave-concave inclined-plane.
Last dental lamina opening and following dental lamina open circles arc are concentric.
The beneficial effects of the utility model are that it is big to clamp diameter range, and fastening pressure is big, and device is simple, and specification requirement and manufacturing cost height are easy to maintenance.
