Abstract
The utility model relates to a hydraulic clamping head of a self-lubricating sliding bearing plate and belongs to test equipment of mechanics of materials. A liner plate is fixedly connected with a clamping head body by virtue of a bolt; the self-lubricating sliding bearing plate is fixedly connected with a groove of the liner plate; a jaw is fixedly clamped with a sliding block; the inclined surface of the sliding block is slidingly connected with the self-lubricating sliding bearing plate; a piston is slidingly connected with the bottom of the clamping head body; and the upper end of the piston is fixedly connected with a tray. The hydraulic clamping head has the advantages of novel and simple structure, low cost and wide application field. The hydraulic clamping head is not only applicable to universal testing machines, but also applicable to steel strand tensile testing machines.
Description
Technical field
The utility model belongs to the materials mechanics experimental device, refers in particular to a kind of testing machine hydraulic chuck.
Background technology
The structure of the universal hydraulic testing machine hydraulic chuck of selling on the market at present, is the form that the slide block inclined-plane directly slides on collet body V-type inclined-plane.Slide block is to quench with alloy steel to form, and skin hardness is high, makes yet collet body but is the lower steel-casting of hardness (or nodular cast iron).Thereby collet body inclined-plane quick abrasion or be easy to scratch during the slide block slippage, repair trouble, maintenance cost is high.Except since friction force large, the servo-actuated property of slide block is poor, two side slides move asynchronous or creep, and just must cause that the jaw right alignment changes.
Summary of the invention
The utility model provides a kind of self-lubricating plain bearing plate hydraulic chuck, to solve present hydraulic chuck quick abrasion, problem that maintenance cost is high.
The technical solution of the utility model is: liner plate is fixedly connected with collet body by screw, the self-lubricating plain bearing plate is fixedly connected with the groove of liner plate, the fixedly clamping of jaw and slide block, the inclined-plane of slide block and self-oiling bearing plate are slidingly connected, piston is connected with the collet body basal sliding, and the piston upper end is fixedly connected with pallet.
The utility model has the advantage of: novel structure is simple, and cost is low.Application is wide, is not only applicable to universal testing machine, can also be applied to the steel strand tensile test machine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The loading and unloading sample is realized by the movement of piston; namely be contained on the pallet; piston promotes slide block; fix a self-lubricating plain bearing plate between collet body V-type inclined-plane and the slide block, avoided slide block to contact with the direct of collet body, the graphite that the workplace of self-lubricating plain bearing plate is good with wearing quality, friction factor is little is made; both greatly increased the servo-actuated property of slide block; the off-centre of jaw when having overcome tension test, strong protection chuck body running face again, and eliminated the scratch of collet body inclined-plane.
Claims (1)
1. self-lubricating plain bearing plate hydraulic chuck, it is characterized in that: liner plate is fixedly connected with collet body by screw, the self-lubricating plain bearing plate is fixedly connected with the groove of liner plate, the fixedly clamping of jaw and slide block, the inclined-plane of slide block and self-oiling bearing plate are slidingly connected, piston is connected with the collet body basal sliding, and the piston upper end is fixedly connected with pallet.
