Description

Vertical internal broaching machine
[technical field]
The present invention relates to broaching machine, relate in particular to the vertical internal broaching machine of the various geometry through holes that are used to broach.
[background technology]
Present vertical internal broaching machine all is to adopt cast iron framework, all-hydraulic transmission.There are many defectives in the vertical internal broaching machine of this structure:
1. resource consumption is big: prior art adopts cast steel main body framework up and down, and volume is doted on greatly, complex process etc.
2. energy resource consumption is big: all-hydraulic transmission, power consumption is big, complex structure.
3. the speed of griffing is slow, and anchor clamps are not general: any broaching machine its speed in the broaching process is the same, can not be fast.Master cylinder backhaul withdrawing has certain hour to wait for.Existing defective is that hydraulic delivery cutter speed is slow, and complex structure is changed the broaching tool complexity and lost time.Existing broaching tool afterbody clamps varied, the spring steel ball cassette, have bolt-type etc., defective to be to change different broaching tools need to change different anchor clamps, be more or less the same as the broaching tool size, tail dimension is the same during customized broaching tool, just must change anchor clamps as broaching tool size difference is too big.
4. broaching tool head anchor clamps: existing broaching tool head clamps and all adopts the unpowered automatic clamping of phase piece formula, defective is that broaching tool iron filings in the broaching process hoard around broaching tool all the time downwards, when broaching tool withdraws from chuck, iron filings fall into anchor clamps inner chamber on every side, chuck often occurring blocks, and different broaching tool sizes differ the too big different anchor clamps that need to change, change anchor clamps bothers very much, a general manufacturer provisioned user one to two cover chuck, the user is as increasing other new product, need self-control or customization, cost is quite high.
5. broaching tool follow-rest: existing broaching tool follow-rest all adopts two cylindricals location of broaching tool.Broaching tool and anchor clamps all have machining tolerance, add that long-term use chuck also has wear phenomenon, and the broaching tool center has skew, not on vertical line, influences product quality.
Therefore, existing all-hydraulic vertical internal broaching machine complex structure, inefficiency, energy resource consumption is big, the manufacturing cost height, the price height, general medium-sized and small enterprises can't bear.
[summary of the invention]
Purpose of the present invention solves the problems of the prior art exactly, proposes a kind of vertical internal broaching machine, can optimize structure, and increases work efficiency, and reduces energy resource consumption, reduces manufacturing cost.
For achieving the above object, the present invention proposes a kind of vertical internal broaching machine, comprise vertical frame, broaching tool, main hydraulic transmission assembly, described main hydraulic transmission assembly is installed on the vertical frame, also comprise pneumatic pinch mechanism, griffe portable plate, griffe cylinder, griffe the portable plate guide pillar, pneumatic plate mechanism, described pneumatic pinch mechanism can clamp the afterbody of broaching tool, pneumatic plate mechanism can clamp the head of broaching tool, pneumatic pinch mechanism is fixed on griffes on the portable plate, griffing portable plate is arranged on and griffes on the portable plate guide pillar, griffe cylinder with griffe the portable plate guide pillar and be connected, can control and griffe the portable plate guide pillar and move up and down, pneumatic plate mechanism is fixed on the main hydraulic transmission assembly; Described pneumatic plate mechanism comprises plate cylinder, plate connecting rod, plate, and described plate cylinder is connected with the plate connecting rod, can control plate connecting rod move left and right, and the plate connecting rod is fixedlyed connected with plate, and plate is clamped the head of broaching tool.
