Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Example 1

As shown in fig. 1-2, the hydraulic clamping device for square workpieces provided by the utility model comprises a placing platform 1, a workpiece main body 6 and clamping assemblies symmetrically arranged on the placing platform 1. The clamping assembly comprises a bearing piece 2, and adjusting pieces and clamping blocks 5 are symmetrically arranged on the bearing piece 2 front and back. The two clamping blocks 5 are respectively connected to the left side and the right side of the adjusting piece in a sliding mode.

The adjusting piece comprises an oil cylinder movable block 3, wherein limiting blocks 4 are connected to the front side and the rear side of the oil cylinder movable block 3 through bolts, and the limiting blocks 4 are in sliding connection with the clamping blocks 5.

In the present embodiment, the number of the workpiece main bodies 6 is determined according to the number of the clamping blocks, and further, six workpiece main bodies can be fixed at one time in the present embodiment at most.

In this embodiment, a hydraulic cylinder for driving is disposed below each oil cylinder movable block 3, so as to realize lifting adjustment.

In this embodiment, the both sides of place platform 1 are provided with the curb plate, and then when carrying out the centre gripping fixed to the work piece main part 6 that the side was placed, the activity of compact heap 5 extrudees work piece main part 6, and then under the effect of place platform 1 curb plate, realizes the centre gripping fixed to work piece main part 6, and the work piece main part 6 of middle part placement then carries out the centre gripping fixed by the clamp block 5 of both sides.

The working principle of the square workpiece hydraulic clamping device based on the first embodiment is as follows: when the product needs to clamp and fix a plurality of workpiece bodies 6, the workpiece bodies are firstly placed on the placing platform 1 in sequence. And the workpiece main body 6 is placed corresponding to the position of the clamping block 5. When the workpiece main body 6 is clamped and fixed, the hydraulic cylinder correspondingly arranged drives the oil cylinder movable block 3 to descend. When the oil cylinder movable block 3 moves, a plurality of limiting blocks 4 arranged on the oil cylinder movable block are synchronously driven to synchronously adjust. The movement of the limiting block 4 in turn drives the clamping block 5 in a pressing manner, so that it clamps and fixes the corresponding workpiece body 6.

Example two

As shown in fig. 1, based on the first embodiment, this embodiment further includes: the carrier 2 is formed by three T-shaped plates which are distributed at linear intervals and are connected to the top of the placement platform 1 by bolts. The symmetrical adjusting parts are respectively arranged in the corresponding interval gaps. The bottom of the clamping block 5 is integrally provided with a slide bar which is connected with the bottom groove of the T-shaped plate in a sliding way.

In this embodiment, one side of the clamping block 5, which is close to the adjusting member, is an inclined surface, while both sides of the limiting block 4 are inclined surfaces, and the inclined surfaces of the two are close to each other, so that the clamping block 5 is forced to squeeze along with the movement of the adjusting member.
