Abstract

The invention discloses a special clamp for drilling. The special clamp comprises a fixed ejection plate, a discharging plate, a sliding plate, a base plate and a cylinder, wherein the cylinder is fixed on the base plate; a piston of the cylinder is fixed on the sliding plate; the sliding plate is provided with three clamping claws; the lower side of the fixed ejection plate is provided with a guide column, and the discharging plate penetrates through the three clamping claws and is then sleeved on the guide column; the sliding plate is sleeved on the guide column; and the fixed ejection plate is provided with a preformed hole. By adopting the special clamp, drilling of a hole at the center of a large head of a crank can be fully ensured, and an accurate benchmark can be provided for subsequent machining. Moreover, the clamp can machine all cranks without adjusting, and waste produced in adjustment of cranks can be reduced.

Description

A kind of dedicated fixture for drilling
Technical field
The present invention relates to a kind of anchor clamps, specifically a kind of dedicated fixture for drilling.
Background technology
When producing bicycle crank, because the long shrinkage of forge hot crank heat, overall dimensions are inaccurate, and adopt anchor clamps to bore 12.1 holes always, and the center, hole can not accurately be located, anchor clamps are fixed, so the crank head dimensions more greatly, the hole will be inwardly more partially, and is a little bit smaller, the hole will outwards more partially, not reach the standard at complete center; And all processing of crank all is processing take 12.1 holes as benchmark.So, this hole just do not having a strong impact on outward appearance and following process.And, when changing specifications and models, all need anchor clamps are carried out artificial adjustment at every turn, lose time, simultaneously the easy careless generation waste product that is out of tune owing to operating personnel.
Summary of the invention
The problem that exists in order to overcome prior art the purpose of this invention is to provide a kind of dedicated fixture for drilling, guarantees hole drill fully at the center of crank major part by this exclusive clamps prodigiosin, for following process provides accurately benchmark; And anchor clamps adjustment that it goes without doing can be processed all cranks, reduces the waste product in the crank accent machine process.
The objective of the invention is to be achieved through the following technical solutions:
A kind of dedicated fixture for drilling is characterized in that: this special fixture comprises fixedly die pad, stripper, sliding panel, bedplate and oil cylinder, and oil cylinder is fixed on the bedplate; Oil cylinder piston is fixed on the sliding panel; Be provided with three jaws at sliding panel; Be provided with guide pillar at fixing die pad downside, stripper is sleeved on the guide pillar after passing three jaws; Sliding panel is sleeved on the guide pillar; Be provided with preformed hole at fixing die pad.
Among the present invention, preformed hole is arranged on the fixedly center of die pad.The position of three jaws and crank major part are suitable.Guide pillar is four, and four guide pillars are separately positioned on the fixedly place, four angles of die pad.
Among the present invention, 4 guide pillars connect all clamping plate, and oil cylinder is fixed on the bedplate, and oil cylinder piston is fixed on the sliding panel, and special-purpose three jaws in 12.1 holes are fixed on the sliding panel, and stripper is installed on the guide pillar, and loads onto fixedly die pad on the guide pillar top.
In the course of work: the crank major part is put in special-purpose three jaws in hole, utilize the rising of oil cylinder piston, drive the rising of sliding panel, three-jaw is clamped the tapered cylinder of crank major part, withstand on the plane of fixing die pad, thereby realize the crank automatic capturing, drill bit is being holed under the preformed hole of fixed head, has guaranteed that each crank boring is all at the center of crank major part.Utilize the decline of oil cylinder, finish the process of discharging.
Compared with prior art, the present invention can guarantee hole drill fully at the center of crank major part, for following process provides accurately benchmark; And anchor clamps adjustment that it goes without doing can be processed all cranks, reduces the waste product in the crank accent machine process.
The present invention is fit to the processing crank, and particularly crank 12.1 holes processing need not be transferred anchor clamps again, directly processing.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
A kind of brill of the present invention 12.1 hole special fixtures, this special fixture comprises fixedly die pad 5, stripper 4, sliding panel 2, bedplate 8 and oil cylinder 7, oil cylinder 7 is fixed on the bedplate 8; Oil cylinder piston is fixed on the sliding panel 2; Be provided with special-purpose three jaws 3 in 12.1 holes at sliding panel 2; The position of three jaws and crank major part are suitable.Be provided with 1, four guide pillar 1 of four guide pillars at fixing die pad 5 downsides and be separately positioned on the fixedly place, four angles of die pad 5.Stripper 4 is sleeved on the guide pillar 1 after passing three jaws 3; Sliding panel 2 is sleeved on the guide pillar 1; Be provided with preformed hole 6 in fixing die pad 5 centers.
During work, the crank major part is put in special-purpose three jaws in hole, utilize the rising of oil cylinder piston, drive the rising of sliding panel, three-jaw is clamped the tapered cylinder of crank major part, withstands on the plane of fixing die pad, thereby realizes the crank automatic capturing, drill bit holing under the preformed hole of fixed head, guaranteed that each crank boring is all at the center of crank major part.Utilize the decline of oil cylinder, finish the process of discharging.
Adopt the present invention to do the product size standard stable; Save the accent machine mode transfer time, during originally every change model specification, anchor clamps adjustment and examination processing are more than 1 hour, and these anchor clamps do not need to carry out the anchor clamps adjustment to all models, do not have adjusting machine time, and material is directly gone up machine and all can be processed.Saved cost, it is defective products or waste product that specifications and models of former replacing need be adjusted 10 materials, calculates to change 2 specifications every day, adds up to 20,5 yuan of every costs, 100 yuan altogether.
