It has light weight. A technology for manufacturing said fixture includes such steps as casting said drill body with the Al alloy or Mg allow or Al-Mg alloy having the density of 2.0-3.5 g/cm3, and machining.
Description
Technical field
The present invention relates to a kind of drill chuck, relate in particular to a kind of drill chuck that is installed on machining equipment or the electric hand tool.
Background technology
Hand fastening drill clutch generally comprises drill body, nut, jaw, rotary sleeve, has most drill chuck also to be provided with the back cover.Drill body is as the agent structure of drill chuck, its rear end is provided with the connecting hole that is connected with driving device, be processed with the jaw hole of inclination at its front end to middle part, jaw by with being threaded of the nut on drill body of being axially located, under the rotary sleeve that is connected with nut drives, in the jaw hole, advance and retreat, thereby clamp or the drilling tool that gets loose.At present, drill body adopts round steel as raw material, forms through multi-step process car system.This drill chuck shortcoming is: drill body is raw material with the round steel, forms through multi-step process car system, and the iron filings under the car account for 40%～50% of raw material, waste time and energy, and weight are bigger.
Summary of the invention
Technical problem to be solved by this invention provides a kind of hand fastening drill clutch that overcomes above-mentioned defective.For this reason, the present invention by the following technical solutions: it comprises drill body, rotary sleeve, nut, the jaw that is connected with nut thread, is provided with the jaw hole of inclination in the drill body, described drill body by density at 2.0～3.5g/cm
3Aluminium alloy, magnesium alloy or almag make.Because adopt above technical scheme, the present invention selects 2.0～3.5g/cm
3Aluminium alloy, magnesium alloy or almag, when keeping the hand fastening drill clutch performance, simplify the car system operation of drill chuck, a large amount of wastage of material that reduce, simultaneously, more traditional hand fastening drill clutch has reduced by nearly 1/3 weight, this is for electric hand tool, its meaning more strengthens, and it makes that operation is lighter and handier nimble, and has reduced the consumption of energy.
The present invention also can be provided with back cover, and back cover can be by connecting configuration and described drill body formation integral structure, this integral structure by density at 2.0～3.5g/cm
3Aluminium alloy, magnesium alloy or almag make.Like this, can further simplify the manufacturing process of drill chuck, improve drill chuck surface impact resistance, make the drill chuck profile more attractive in appearance.Certainly, also can only be drill body by density at 2.0～3.5g/cm
3Aluminium alloy, magnesium alloy or almag make.
Being connected configuration and can adopting various ways of back cover and drill body is connected drill body such as being the capping shape with the bottom of afterwards overlapping.Being connected configuration and also can being located at by the back cover and surrounding jaw advance and retreat position in the zone of described drill body and back cover connects the jaw hole that is provided with in the configuration for the inclination of jaw advance and retreat.Like this, further reducing under the situation of drill chuck weight, making the integral structure of drill body and back cover more firm, structure is compact more.
Another technical problem to be solved by this invention provides a kind of manufacture method that reduces the hand fastening drill clutch of wastage of material.For this reason, the present invention is by the following technical solutions: it may further comprise the steps:
1), with density at 2.0～3.5g/cm
3Aluminium alloy, magnesium alloy or almag in mould, be cast as the drill body blank,
2), on lathe, the connecting hole that the rear end processing of the blank of step " 1) " is cooperated with driving device, with the blank front end cylindrical finish turning of step " 1) ", the blank of step " 1) " is processed the jaw hole.
Because adopt technique scheme, the present invention can avoid in the classical production process, 40%～50% chipping allowance waste because of car system drill body causes has greatly reduced machining period.
Step " 1) " but the rear end casting of drill body blank the base hole of the connecting hole that cooperates with driving device, the base hole in jaw hole are arranged.Like this, can further reduce cost and machining period.
In step " 1) ", when casting drill body blank, the back cover of forging molding and drill body one simultaneously.Like this, can further simplify manufacturing procedure.
