Abstract
The utility model discloses a can eliminate assembly error's lathe knife -changing arm, which comprises a body, the body both ends are provided with the jack catch respectively, the body middle part is provided with a step axle hole, it has the tool changing axle to peg graft in the step axle hole, the tool changing axle is fixed at the flange bottom the step axle hole through a setting on the body, be provided with the cutting stylus around the step axle hole of body top, the epaxial body up end department of being close to of tool changing is provided with the circumference scale. The utility model discloses in the time of can making knife -changing arm assemble on the lathe, the locking reservation stroke of conveniently setting for directly perceived to make knife -changing arm with shaft locking back have simultaneously just with a sword section of thick bamboo and main shaft to heart degree, improvement assembly efficiency.
Description
[technical field]
This utility model is related to the technical field of machine tool, the particularly technical field of lathe tool change arm.
[background technology]
In numerical control machining center, main shaft, meanwhile, main shaft are docked to by arranging numbered cutter in tool magazine by tool change arm
In cutter taken off by tool change arm and restore in tool magazine, two actions complete simultaneously, so needing strict guarantee tool changing
Two claws concentricity with knife cylinder, main shaft in tool magazine respectively of arm, otherwise easily produces grazing in tool change arm crawl cutter
Abrasion；
Tool change arm has optimal assembling orientation in theory, but during practical set, due to rigging error and locking
When additional mobile factor, lead to tool change arm accurate assembly more difficult, greatly constrain the packaging efficiency of lathe.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of lathe eliminating rigging error
Tool change arm, can make tool change arm in lathe over-assemble, and intuitive and convenient ground sets the reserved stroke of locking so that tool change arm with
Just there is after mandrel locking the central degree with knife cylinder and main shaft simultaneously, improve efficiency of assembling.
For achieving the above object, the utility model proposes a kind of lathe tool change arm eliminating rigging error, including this
Body, described body two ends are respectively arranged with claw, are provided with a step axle hole machine, described step axle hole machine interpolation in the middle part of described body
It is connected to tool changing axle, described tool changing axle is fixing on the body by a flange being arranged on step axle hole machine bottom；Described
It is provided with cutting stylus around step axle hole machine above body, described tool changing axle is provided with circular scale near body upper end surface.
The beneficial effects of the utility model: this utility model passes through to arrange quarter on the body of tool change arm along at step axle hole machine
Pin, and circular scale is set on cutter shaft, when needing body is locked on tool changing axle, in order to eliminate the basis that coupling mechanism force is brought
Body circumference sliding in that context it may be convenient to by body towards locking torque the presetting special angle of opposite direction, thus eliminating circumferential sliding
Amount, it is ensured that the tool changing arm body after locking is in correct position, improves the efficiency of assembling of tool change arm.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[brief description]
Fig. 1 is the overall structure diagram of the lathe tool change arm that this utility model can eliminate rigging error；
Fig. 2 is the polycrystalline substance schematic diagram of the lathe tool change arm that this utility model can eliminate rigging error.
In figure: 1- body, 2- claw, 3- tool changing axle, 4- circular scale, 5- cutting stylus, 6- flange.
[specific embodiment]
Refering to Fig. 1 and Fig. 2, a kind of lathe tool change arm eliminating rigging error of this utility model, including body 1, described
Body 1 two ends are respectively arranged with claw 2, be provided with a step axle hole machine, be plugged with described step axle hole machine in the middle part of described body 1
Tool changing axle 3, described tool changing axle 3 is fixed on described body 1 by a flange 6 being arranged on step axle hole machine bottom；Described
It is provided with cutting stylus 5 around the step axle hole machine of body 1 top, described tool changing axle 3 is provided with circular scale near body 1 upper end surface
4.
Utility model works process:
A kind of lathe tool change arm eliminating rigging error of this utility model in the course of the work, body 1 is plugged into and changes
On cutter shaft 3, flange 6 is connected with tool changing axle 3 bottom by screw at the ladder axis hole of body 1 bottom, now will not change
Cutter shaft 3 is locked with body 1, and body 1 can rotate on tool changing axle 3；Claw 2 is adjusted with the knife cylinder in main shaft or tool magazine
To concentric position, then body 1 is adjusted back a special angle (concrete numerical value for this angle along the contrary direction of locking torque
During being locked by test, the slippage of body 1 determines, the angle of setting can be read from cutting stylus 5 and circular scale 4
Take), then by screw-driving, so that body 1 is locked with tool changing axle 3.
This utility model, by arranging cutting stylus along at step axle hole machine on the body by tool change arm, and setting circle on cutter shaft
Zhou Kedu, when needing body is locked on tool changing axle, in order to eliminate the body circumference sliding that coupling mechanism force is brought, can facilitate
By body towards locking torque the presetting special angle of opposite direction, thus eliminate circumferential slippage it is ensured that locking after tool changing
Arm body is in correct position, improves the efficiency of assembling of tool change arm.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
