Description

A kind of tilting tool change arm
Technical field
This utility model relates to the tool change arm of lathe, particularly relates to a kind of tilting tool change arm.
Background technology
At present fixed column type horizontal machining center machine uses cost relatively low and speed and the higher cam-type mechanical hand tool changing mode of reliability mostly, and the stop position of tool change arm is at plumbness and can not adjust attitude.When workbench reaches near tool change arm near zone, if workpiece size is somewhat larger, will produce with tool change arm and interfere.
In order to solve this interference problem, occurring that at present a kind of mode using tool magazine movable avoids interference with, during machine tooling, tool magazine is stepped back, before when needing tool changing, tool magazine moves on to.But owing to the volume and weight of tool magazine itself is the biggest, often change a cutter to be required for moving forward and backward once, although solving the interference problem of tool arm and workpiece, but bring several new problems: need to increase movable guide rail and driving means and cause structure to complicate, add cost and but reduce reliability simultaneously;Often change a cutter and will move forward and backward huge tool magazine, tool change time can be caused elongated, and the bad stability of tool change position.
Summary of the invention
This utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of tilting tool change arm, and when fixed column horizontal Machining centers uses this tilting tool change arm, tool change arm and workpiece no longer produce interference.
For solving problems of the prior art, the concrete technical scheme of employing is:
A kind of tilting tool change arm, including cam-type transmission case, power transmission shaft, tool change arm, cutter holding head, track-type facilities, frame;Described cam-type transmission case is arranged on the side of cutter holding head, and is fixed in frame;Described power transmission shaft arranges inside cam-type transmission case, and one end connects tool change arm;Described cutter holding head is arranged on track-type facilities, and track-type facilities is vertically installed in frame.
Described cam-type transmission case adjustable take-off (propeller) shaft rotational angle and outreach, and then adjust the attitude of tool change arm, cam-type transmission case also can transmit out cutter.
Described tool change arm two ends are provided with cutter draw-in groove, and it is shaped as U-shaped, and the angle of tool change arm armed state can be in arbitrarily angled with horizontal direction, and this utility model is preferably 30 °, are in outside the range of work of whole lathe and the overall dimensions of workpiece.
A kind of tilting tool change arm specific implementation process is:
The first step: track-type facilities drags cutter holding head to tool changing precalculated position, cam-type transmission case starts to send out cutter, then adjusting drive axis angle makes tool change arm start to turn clockwise 30 ° from armed state, one end cutter draw-in groove buckles the cutter on cutter holding head, and other end cutter draw-in groove buckles the cutter that cam-type transmission case sends out;Second step: cam-type transmission case adjusts power transmission shaft and stretches out, drives tool change arm to be extracted from cutter holding head by cutter;3rd step: cam-type transmission case 1 adjusts power transmission shaft 2 rotational angle so that tool change arm 3 turns clockwise 180 °, by the to be exchanged cutter aligned position being positioned at tool change arm 3 two ends;4th step: cam-type transmission case adjusts power transmission shaft retraction and tool change arm retraction is buckled at two ends cutter, and then inserts respectively in cam-type transmission case and cutter holding head;5th step: cam-type transmission case adjusts drive axis angle so that tool change arm rotates 30 ° counterclockwise, and tool change arm 3 returns to armed state.
By using such scheme, compared with prior art, it has the technical effect that a kind of tilting tool change arm of the present utility model
1. tilting tool change arm well solves the cam-type cutter-exchange mechanism used at fixed column type horizontal Machining centers, and its tool change arm is in the defect of zero point (stop position) Yu the interference problem of workpiece.
2. need not increase the cost of the movable device of tool magazine, still use the mature Cam box mechanism of industry, solve the interference problem with tool change arm when workpiece size is bigger dexterously, ensure that speed and the reliability of tool changing simultaneously.
3. tool change arm can adjust as the case may be with the angle of horizontal direction, and Technological adaptability is more preferable.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the armed state of this utility model a kind of tilting tool change arm;
Fig. 2 is the partial enlargement structural representation of this utility model a kind of tilting tool change arm.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage of greater clarity, below in conjunction with instantiation and referring to the drawings, this utility model is further described.It should be understood that these describe the most exemplary, and it is not intended to limit scope of the present utility model.Additionally, in the following description, eliminate the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.
As shown in one of Fig. 1 to Fig. 2: a kind of tilting tool change arm, including cam-type transmission case 1, power transmission shaft 2, tool change arm 3, cutter holding head 4, track-type facilities 5, frame 6;Described cam-type transmission case 1 is arranged on the side of cutter holding head 4, and is fixed in frame 6;It is internal that described power transmission shaft 2 arranges cam-type transmission case 1, and one end connects tool change arm 3;Described cutter holding head 4 is arranged on track-type facilities 5, and track-type facilities 5 is vertically installed in frame 6;
Described cam-type transmission case 1 adjustable take-off (propeller) shaft 2 rotational angle and outreach, and then adjust the attitude of tool change arm 3, cam-type transmission case 1 also can transmit out cutter;
