Abstract
The utility model relates to a hydraulic clamp, in particular to an in-car surface hydraulic clamp used for shell parts, which comprises a clamp body, a positioning block arranged at the top of the clamp body, and a mandril arranged in the clamp body. The in-car surface hydraulic clamp used for shell parts is characterized in that a plurality of special claws are arranged in the clamp body in a direction perpendicular to the mandril and are movably connected with the clamp body, and slide transition grooves are arranged on a contact plane of the special claws and the mandril. The utility model has the advantages of great clamping force, high clamping accuracy, stable clamping, high work efficiency, simple and convenient operation, convenient mounting, reasonable structure, and the like.
Description
Technical field
The utility model relates to a kind of hydraulically operated fixture, especially relates to a kind of car inner surface hydraulically operated fixture that is used for shell class part.
Background technology
As everyone knows, mostly all there are problems such as chucking power is little, the clamping precision is not high in shell class part car inner surface hydraulically operated fixture in the market, thereby clamping is stable inadequately when having caused processing parts, and inefficiency.The utility model has increased top tip structure at after this problem further investigation newly on the original basis of anchor clamps, this top tip structure can make the axiality of processed shell class part stable more, accurate.With respect to the shell class part car inner surface hydraulically operated fixture of traditional structure, new construction has improved production efficiency when increasing clamping dynamics and clamping precision.
Summary of the invention
The utility model mainly be little at the existing in prior technology chucking power, the clamping precision is low, clamping is stable inadequately, the technical problem of inefficiency etc., provides that a kind of chucking power is big, clamping precision height, clamping are stable, the shell class part car inner surface hydraulically operated fixture of high efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of shell class part car inner surface hydraulically operated fixture, the collet chuck that comprises clamp body and be set in the clamp body upper end, the clamp body below is provided with pull bar, it is characterized in that described clamp body inboard is provided with top, described collet chuck and clamp body junction are provided with clamp body and tiltedly overlap, and are connected by some pad pipes between collet chuck and the pull bar.During processing shell class part, part is close to by its large end face and part pallet end face, the top part centre bore that heads into is located part simultaneously, oil cylinder spurs thread then, thread drives pull bar by the nut adapter sleeve, pull bar is by six pad pipe pulling collet chucks, thereby collet chuck is inwardly clamped part under the effect that clamp body tiltedly overlaps, after part processing finishes, oil cylinder promotes thread, thread drives pull bar by the nut adapter sleeve, and pull bar promotes collet chucks by six pad pipes, and collet chuck unclamps under self flexible effect automatically.
As preferably, described clamp body inside is provided with the part pallet.Part is close to by its large end face and part pallet end face, and the part pallet plays fixing spacing effect.
As preferably, described clamp body end and pull bar junction are provided with sheath.Sheath plays protection and fixing effect, and it is safe and reliable, rational in infrastructure.
As preferably, described tie rod end is connected with thread, and described thread and pull bar junction are provided with clamp body pull-rod nut adapter sleeve.Thread drives pull bar by the nut adapter sleeve, and it is rational in infrastructure, design is ingenious, easy and simple to handle.
As preferably, described thread end is provided with machine tool hydraulic head nut adapter sleeve.Machine tool hydraulic head nut adapter sleeve is used for thread is connected with the machine tool hydraulic head.
Therefore, the utlity model has that chucking power is big, clamping precision height, clamping are stable, high efficiency, characteristics such as easy and simple to handle, rational in infrastructure.
Description of drawings
Accompanying drawing 1 is a kind of structure cutaway view of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
A kind of shell class part car inner surface hydraulically operated fixture, the collet chuck 4 that comprises clamp body 1 and be set in the clamp body upper end, the clamp body below is provided with pull bar 3, the clamp body inboard is provided with top 2, collet chuck and clamp body junction are provided with tiltedly cover 5 of clamp body, manage 6 by some pads between collet chuck and the pull bar and are connected.Clamp body inside is provided with part pallet 7.Clamp body end and pull bar junction are provided with sheath 8.Tie rod end is connected with thread 9, and thread and pull bar junction are provided with clamp body pull-rod nut adapter sleeve 10.The thread end is provided with machine tool hydraulic head nut adapter sleeve 11.
During processing shell class part, part is close to by its large end face and part pallet end face, the top part centre bore that heads into is located part simultaneously, oil cylinder spurs thread then, thread drives pull bar by the nut adapter sleeve, pull bar is by six pad pipe pulling collet chucks, thereby collet chuck is inwardly clamped part under the effect that clamp body tiltedly overlaps, after part processing finishes, oil cylinder promotes thread, thread drives pull bar by the nut adapter sleeve, and pull bar promotes collet chucks by six pad pipes, and collet chuck unclamps under self flexible effect automatically.
