Abstract
The utility model discloses a special fixture for machining a hole with the diameter of 11.5 mm in a bicycle crank. The special fixture includes a feeding claw connected with an air cylinder, a feeding auxiliary support, a drilling hole auxiliary support, a sliding plate, a supporting seat and a base, wherein the feeding claw is arranged at the upper end of the feeding auxiliary support; the lower end of the feeding auxiliary support is arranged on the sliding plate; the sliding plate is arranged on the supporting base; a groove matched with the hole with the diameter of 11.5 mm is formed at the top of the drilling hole auxiliary support; the lower end of the drilling hole auxiliary support is connected with the supporting seat through an X-direction sliding block and an X-direction linear bearing; the supporting seat is connected with the base through a Y-direction sliding block and a Y-direction linear bearing. The special fixture can be used for machining holes with the diameter of 11.5 mm, reduce anthropogenic undesirable factors, improve the machining precision, reduce the labor intensity and improve the working efficiency.
Description
Technical field
The utility model relates to a kind of fixture, specifically 11.5mm hole special fixture in a kind of processing bicycle crank.
Background technology
11.5 traditional hole fixtures utilize the oil pressure drilling machine, when processing work, need workpiece is placed on fixture, manually with its chucking, slightly have tolerance also need adjust again, otherwise boring partially, workpiece is scrapped, and then hole by switch activated drilling machine, after boring is completed, open the chucking fixture, take off workpiece, then carry out operation for the second time.The shortcoming of this mode is: efficient is slow, the location is inaccurate, defective products is many, labor strength is large.
Summary of the invention
The problem that exists in order to overcome prior art, the purpose of this utility model is to provide a kind of 11.5 hole special fixtures, when adopting this special fixture to process 11.5 hole, can reduce artificial undesirable element, and machining accuracy improves; Reduce labour intensity, improved operating efficiency.
The purpose of this utility model is achieved through the following technical solutions:
11.5mm hole special fixture in a kind of processing bicycle crank, it is characterized in that: this fixture comprises feeding claw, feeding supplemental support, boring supplemental support, slide plate, supporting seat and the base that is connected with cylinder, feeding claw is arranged on the upper end of feeding supplemental support, the lower end of feeding supplemental support is arranged on slide plate, and slide plate is arranged on supporting seat; Top in the boring supplemental support is provided with the groove suitable with 11.5 holes, and the lower end of boring supplemental support is connected with supporting seat with the X linear bearing by the X slide block; Supporting seat is connected with base with the Y linear bearing by the Y slide block.
The utility model utilizes cylinder that workpiece is sandwiched on special fixture, Special drill jig is by the measuring and calculating workpiece, boring grab is designed to any X/Y linear axis automatic guiding in the 5mm circumference, utilize 110 of fluted drill to spend the angle, cutting edge and workpiece 110 are spent the angle, and the punching press conical surface is in X/Y direction automatic reclosing machining.When directions X has deviation, be delivered on X-axis by fluted drill and the very little shear action power of workpiece to be machined, thereby guarantee that by the X linear bearing X slide block slides and correcting on X-axis; When Y-direction has deviation, at first this device guarantees the X-axis correcting, same principle then, fluted drill force transmission on Y-axis, thereby guarantee that by the Y linear bearing Y slide block slides and guarantees correcting on Y-axis.
Compared with prior art, the utility model can reduce artificial harmful effect, and machining accuracy improves; Reduce labour intensity, improved operating efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of boring supplemental support in the utility model.
The specific embodiment
11.5mm hole special fixture in a kind of processing bicycle crank, see Fig. 1 and Fig. 2, this fixture comprises feeding claw 9, feeding supplemental support 11, boring supplemental support 12, slide plate 1, supporting seat 2 and the base 3 that is connected with cylinder, feeding claw 9 is arranged on the upper end of feeding supplemental support 11, the lower end of feeding supplemental support 11 is arranged on slide plate 1, and slide plate 1 is arranged on supporting seat 2.Top in boring supplemental support 12 is provided with the groove 10 suitable with 11.5 holes, is connected with the X linear bearing and is connected with supporting seat 2 by X slide block 5 in the lower end of boring supplemental support 12; Supporting seat 2 is connected with the Y linear bearing by Y slide block 7 and is connected with base 3.
During boring, only need workpiece 8 is placed in fixture, press starting switch, fixture Automatic-clamping workpiece, automatically loosen clamp jaw after holing, completing, personnel only need do the part of knocking off, by switch, get three actions of workpiece and get final product.Utilize 110 of fluted drill to spend the angle, cutting edge and workpiece 110 are spent the angle, and the punching press conical surface is at X/Y direction automatic reclosing.When directions X has deviation, be delivered on X-axis by fluted drill and the very little shear action power of workpiece to be machined, thereby guarantee that by the X linear bearing X slide block slides and correcting on X-axis; When Y-direction has deviation, at first this device guarantees the X-axis correcting, same principle then, fluted drill force transmission on Y-axis, thereby guarantee that by the Y linear bearing Y slide block slides and guarantees correcting on Y-axis.
Product size that the utility model is done is stable; Machining accuracy improves, approximately 30 of minimizing borehole drilling materials every day, and staff labor intensity reduces, and operating efficiency has improved 30%.
