Abstract
The utility model discloses a positioning pin for preventing a clamp base from being damaged. A principle structure is that the positioning pin is inserted into a positioning pin base, and the bottom of the positioning pin base is fixed with the positioning pin through a screw. The positioning pin base and the clamp base are assembled through a middle sleeve, a screw hole is formed in the upper end of the positioning pin base, and the upper end of the positioning pin base is fastened with the clamp base. The bottom of the positioning pin and the positioning pin base are fixed in an eccentric fastening mode. Two separated columns are machined at the upper portion of the positioning pin, the top ends of the columns are circular-arc-shaped, and a groove is formed between the lower ends of two columns and the positioning pin body. The positioning pin is simple in structure, the positioning pin and the clamp base are split, and if a machined part is inaccurately positioned due to the conveying problem of a conveying belt, the upper end of the positioning pin is first broken off, and the machining clamp base is not damaged. Due to the fact that the positioning pin is simple and convenient to install, the clamp damage possibility is reduced, and the maintenance time is saved, the running efficiency of a production line is ensured, and the labor productivity is improved.
Description
Technical field
The utility model belongs to machine components, is specifically related to a kind of device that is applicable to protect machining fixture base.
Background technology
Cylinder body processing is the mach core of engine, and wherein the requirement of three hole boring machining accuracies of cylinder body is very high.In three hole boring process, be all to adopt conveyer belt feeding at present, even if conveyer belt appears in occasional, conveying workpieces is not in place, and fixture still enters and compresses operation operating mode.Now, because work piece is not accurately located on fixture, so can cause alignment pin fracture, clamp base cracks.Because clamp base maintenance difficulty is larger, need integral demounting to keep in repair, maintenance cycle needs more than 15 days, and the repetition installation accuracy after maintenance is also difficult to reach initial precision, thereby can reduce the yields of cylinder body processing, causes very large waste.If therefore propose a kind of alignment pin that can prevent that clamp base from damaging, make it occur when workpiece beat compresses to guarantee that first this alignment pin fractures, and do not damage clamp base.Because alignment pin is more easily reinstalled, therefore reduced probability and maintenance time that fixture damages, guaranteed the continuous running of production line.
Summary of the invention
The purpose of this utility model is that a kind of alignment pin that prevents that clamp base from damaging is provided.
Below the technical solution of the utility model and theory structure are described.Prevent that the alignment pin that clamp base is damaged from comprising: alignment pin pedestal, intermediate sleeve, clamp base, screw, alignment pin and spring washer etc.Its theory structure is: alignment pin inserts in alignment pin pedestal, in alignment pin base bottom, by screw and alignment pin, fixes, and screw is furnished with spring washer.Alignment pin pedestal fits together by intermediate sleeve and clamp base, in alignment pin pedestal upper end, is provided with screw hole, fastening by screw and clamp base.
The beneficial effect of feature of the present utility model and generation is: simple in structure, alignment pin and clamp base split design, if conveyer belt conveying workpieces is not in place, causes work piece to be decided to be when inaccurate, first alignment pin upper end fractures, and can not damage machining fixture base.Due to alignment pin simple installation, not only reduced the probability of fixture damage but also saved maintenance time, guaranteed the running efficiency of production line, improved labor productivity.
Accompanying drawing explanation
Shown in accompanying drawing be theory structure sketch of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, structure of the present utility model is described further.
Prevent the alignment pin that clamp base is damaged, its concrete structure is: alignment pin 5 is embedded in alignment pin pedestal 1, in alignment pin base bottom, by screw 4 and alignment pin, fixes, and screw is furnished with spring washer 6.Alignment pin pedestal fits together by intermediate sleeve 2 and clamp base 3, in alignment pin pedestal upper end, is provided with screw hole, fastening by screw and clamp base.Alignment pin top processes two columns that separate, and the top of column is circular-arc, processes a groove between the low side of two columns and alignment pin body.Fixed form between alignment pin bottom and alignment pin pedestal is eccentric fastening.
Alignment pin pedestal and corresponding alignment pin are assemblied in clamp base as an associate member.Fixed form between alignment pin bottom and alignment pin pedestal is designed to eccentric fastening, its objective is and prevents that alignment pin from producing autorotation.Alignment pin top processes two columns that separate, and the low side of column (and between alignment pin body) processes a groove, its objective is when alignment pin is subject to cross force impact, at this neck, very easily rupture, this alignment pin is equivalent to " fuse " in circuit.Described " groove " is equivalent to (processing one) " escape " in machined, and the width of this groove and the degree of depth are not had to specific (special) requirements, generally according to lathe, by the size of cutting knife, decides.
During use, with the alignment pin being arranged on fixture, the workpiece of needs processing is positioned to (workpiece is provided with corresponding locating hole).If because transmission problem causes workpiece location inaccurate, compress operation operating mode and now workpiece has been entered, when workpiece is stressed, the neck of alignment pin ruptures immediately so, thereby has protected fixture injury-free.
The utility model effect on the three hole fixture for boring machine for engine body processing is very good, when there is conveyer belt conveying workpieces situation not in place, the accident of fixture never occurs to damage, and has reduced the maintenance time of equipment and has manufactured maintenance cost.
