Abstract

The utility model relates to a hinge synchronous type hydraulic horizontal pushing and stretching clamp and belongs to a clamp. A connecting shaft is fixedly connected with a clamp body through screws; two oil cylinder inner chambers are processed on the left side and the right side of the clamp body; oil cylinder end caps are fixedly connected with the clamp body through high-strength screws; pistons with seal rings are assembled in the oil cylinder inner chambers on the two sides of the clamp body; push-pull rods are fixedly connected with the rod ends of the left and the right pistons through screws; fixture blocks are connected with the rod ends of the left and the right pistons in a sleeving manner, and are fixedly connected with the left and the right piston through anti-rotation pins; a cover plate is fixedly connected with a hinge part on the clamp body through small screws; ultrahigh pressure oil pipes are fixedly connected with the oil cylinder end caps at two ends of the clamp body respectively; a centring shaft is fixedly connected with a back sunk groove of the clamp body through countersunk head screws after being connected with a shaft retaining ring I and a shaft retaining ring II in a penetrating manner; and pin shafts are connected with junction plates and central junction plates. The hinge synchronous type hydraulic horizontal pushing and stretching clamp has the advantages that the structure is novel, the stress state of a hinge is good, components are not liable to be damaged, and the maintenance is simple, labor-saving and time-saving.

Description

Hinge synchronous mode hydraulic pressure horizontal sliding stretching clamp

Technical field

The utility model belongs to anchor clamps, refers in particular to a kind of hydraulic pressure flat push type anchor clamps.

Background technology

Along with the development in various markets, hydraulic pressure flat push type clamp technology is also more and more ripe.Existing hydraulically operated fixture majority is to carry out synchronously with the form of rack-and-pinion, and what have meshes in the clamp body passage, have in the clamp body external toothing; The adjusting play difficulty, poor reliability is relatively wasted time and energy in debugging; The rack-and-pinion stress is bad during clamping work pieces, and attaching parts are prone to produce phenomenon of rupture, when maintenance, need dismantle oil cylinder; Cumbersome, stress causes damage parts synchronously.

Summary of the invention

The utility model provides a kind of hinge synchronous mode hydraulic pressure horizontal sliding stretching clamp; The rack-and-pinion stress is bad during with the solution clamping work pieces, and attaching parts are prone to produce phenomenon of rupture, when maintenance, need dismantle oil cylinder; Cumbersome, stress causes the problem of damage parts synchronously.

The technical scheme of the utility model is: connecting axle is screwed with clamp body and is connected; At two cylinder cavities of clamp body left and right sides processing, cylinder cover is fixedly connected through high-strength bolt with clamp body, and piston is equipped with in the cylinder cavity that sealing ring is assembled to the clamp body both sides; Pull bar is fixedly connected with the rod end of left and right sides piston through screw; The rod end socket of fixture block and left and right sides piston, stop pin is fixedly connected fixture block with left and right sides piston, and cover plate is fixedly connected with hinge fraction on the clamp body through Screw; The super-pressure oil pipe is fixedly connected with the cylinder cover at clamp body two ends respectively; After centralized positioning axle and shaft retaining ring one, shaft retaining ring two cross-under, be fixedly connected with the back deep gouge of clamp body through sunk screw, bearing pin with win in succession, cross-under is won at the center in succession.

The advantage of the utility model is: novel structure, and the hinge stress is good, and parts are not fragile, and are easy to maintenance time saving and energy saving.

The specific embodiment

Connecting axle 1 is screwed with clamp body 2 and is connected; At two cylinder cavities 5 of clamp body 2 left and right sides processing, cylinder cover 3 and clamp body 2 are fixedly connected through high-strength bolt, and piston 4 is equipped with in the cylinder cavity 5 that sealing ring is assembled to clamp body 2 both sides; Pull bar 6 is fixedly connected with the rod end of left and right sides piston 4 through screw 7; The rod end socket of fixture block 8 and left and right sides piston 4, stop pin 9 is fixedly connected fixture block 8 with left and right sides piston 4, and cover plate 10 passes through Screw and is fixedly connected with hinge fraction on the clamp body 2; Super-pressure oil pipe 16 is fixedly connected with the cylinder cover 3 at clamp body 2 two ends respectively; After centralized positioning axle 12 and shaft retaining ring 1, shaft retaining ring 2 18 cross-under, be fixedly connected with the back deep gouge of clamp body 2 through sunk screw 17, bearing pin 14 and win 13 in succession, 15 cross-under are won at the center in succession.

Two oil cylinders are arranged on clamp body, when two oil cylinders clamp simultaneously, adopt the hinge type synchronization structure, solve synchronous stress and cause the damage parts phenomenon.
