Abstract
The invention relates to tooling clamps for a bearing production process and particularly relates to a bearing end cap machining clamp. The machining clamp comprises an intermediate, wherein the upper end of the intermediate is connected with a clamp body, the lower end of the intermediate is connected with a lower connecting body, a through hole is formed in the revolving center of the intermediate, a second guide sleeve is arranged in the through hole, a connecting rod is arranged in a guide sleeve in a sliding manner, the lower end of the connecting rod extends out of a hole formed in the center part of the lower connecting body, and the upper end of the connecting rod is fixedly connected to a jacking rod; the lower end of the clamp body is provided with a cavity, a jacking plate is arranged in the cavity, and the jacking rod is connected to the jacking plate; four guiding holes are uniformly formed in the outer side of the through hole of the intermediate, and a first guide sleeve and a butterfly-shaped spring are respectively arranged in each guiding hole. By adopting the machining clamp, the machining efficiency of a bearing end cap mass-production process can be increased, and meanwhile, the problem that the accuracy cannot be guaranteed when universal clamping chucks are adopted to clamp is solved.
Description
Technical field
The present invention relates to the frock clamp used in the Production of bearing process, specifically a kind of bearing (ball) cover clamp for machining.
Background technology
In prior art, for the processing of bearing (ball) cover, normally adopt the hydraulic pressure scroll chuck to carry out the clamping bearing (ball) cover, this kind of installation way usually can be controlled improperly due to radial compaction power, and causes the situation that occurs that distortion is overproof; Need twice clamping when the end face of Vehicle Processing bearing (ball) cover both sides, the axiality of twice clamping, the depth of parallelism of two sides can't all guarantee simultaneously; In addition, twice clamping process time is long, efficiency is not high in practice.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of bearing (ball) cover clamp for machining is provided, adopt this clamp for machining can improve the working (machining) efficiency in the bearing (ball) cover batch production process, avoided adopting the universal chuck clamping can't guarantee the problem of precision simultaneously.
According to technical scheme of the present invention: a kind of bearing (ball) cover clamp for machining, it is characterized in that: comprise intermediate, described intermediate upper end jockey body, lower end connects lower connector, the centre of gyration of described intermediate offers through hole, built-in the second guide pin bushing in through hole, and connecting rod slides and is arranged in described guide pin bushing, and the connecting rod lower end from stretch out in the hole offered, connector middle part, described connecting rod upper end is fixedly connected on push rod; The clamp body lower end has a cavity, in this cavity, is provided with top board, and push rod is connected on described top board; On described intermediate, the through hole outside is uniform arranges four pilot holes, be equipped with the first guide pin bushing, butterfly spring in each pilot hole, the guide pillar lower end is placed on lower connector in the through hole corresponding to described pilot hole place, guide pillar top columnar part is successively through butterfly spring, the first guide pin bushing, the guide pillar upper end is connected on top board, and the briquetting lower end on described clamp body is connected in the guide pillar top.
As a further improvement on the present invention, described intermediate upper end has cavity, and lower end has projection, and clamp body is connected in described cavity, and the first bolt is connected to one described intermediate and clamp body; Lower connector upper end is connected on described projection, and the described lower connector of the second bolt-through and the second bolt upper end are fixedly connected on described intermediate.
Technique effect of the present invention is: the clamp pressing workpiece adopts the disk spring axial compression, and pretightning force can be regulated.Can effectively avoid part radial compaction problem on deformation; The frock claw unclamps and utilizes numerically controlled lathe to carry the rotating hydraulic cylinder jacking can to unclamp, and reduces workman's manipulation strength; Clamped one time completes the tow sides processing content of whole workpiece, and 100% guarantees that parallelism of two planes requires, the axiality requirement; Process a workpiece used time and be original 1/3, improve working (machining) efficiency.
