Abstract
The invention discloses an inclined type tool replacement arm which comprises a cam type transmission box, a transmission shaft, a tool replacement arm, a tool clamping head, a guide rail device and a rack. The inclined type tool replacement arm well solves the problem that the tool replacement arm of a cam type tool replacement mechanism adopted by a fixed column type horizontal machining center interferes with a workpiece at a zero point (stop position); the cost of a device for enabling a tool magazine to move front and back is not needed to be increased; a matured cam box mechanism is still used, so that the problem of interference with the tool replacement arm when the size of the workpiece is relatively large is ingenious solved; meanwhile, the speed and the reliability of tool replacement are guaranteed; and an included angle between the tool replacement arm and the horizontal direction can be adjusted according to a specific condition, so that the technological adaptability is higher.
Description
Technical field
The present invention relates to the tool change arm of lathe, more particularly to a kind of tilting tool change arm.
Background technology
At present mostly using the cam-type manipulator tool changing mode that cost is relatively low and speed and reliability are higher, the stop position of tool change arm is at plumbness and can not adjust attitude fixed column type horizontal machining center machine.When workbench is reached near tool change arm near zone, if workpiece size is somewhat larger, interference will be produced with tool change arm.
In order to solve this interference problem, occur at present it is a kind of by the way of tool magazine is movable avoiding interference with, tool magazine is stepped back during machine tooling, before tool magazine is moved on to when needing tool changing.But because the volume and weight of tool magazine itself is all larger, often change a knife and be required for moving forward and backward once, although solve the interference problem of tool arm and workpiece, but while bring several new problems：Need the movable guide rail of increase and driving means and cause complex structure, increased cost and but reduce reliability；Often changing a knife will move forward and backward huge tool magazine, and tool change time can be caused elongated, and the bad stability of tool change position.
The content of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, there is provided a kind of tilting tool change arm, and when fixed column horizontal Machining centers adopts the tilting tool change arm, tool change arm no longer produces interference with workpiece.
To solve 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；The cam-type transmission case is arranged on the side of cutter holding head, and is fixed in frame；The power transmission shaft is arranged inside cam-type transmission case, one end connection tool change arm；The cutter holding head is arranged on track-type facilities, and track-type facilities are vertically installed in frame.
The adjustable take-off (propeller) shaft rotational angle of the cam-type transmission case and outreach, and then the attitude of tool change arm is adjusted, cam-type transmission case also can transmit out cutter.
The 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 and horizontal direction can be in arbitrarily angled, and the present invention is preferably 30 °, the range of work in whole lathe and outside the appearance and size of workpiece.
A kind of tilting tool change arm specific implementation process is：
The first step：Track-type facilities drag cutter holding head to tool changing precalculated position, cam-type transmission case starts to send out cutter, then adjusting drive axis angle causes tool change arm to 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 adjustment power transmission shaft stretches out, and drives tool change arm to extract cutter from cutter holding head；3rd step：Cam-type transmission case 1 adjusts the rotational angle of power transmission shaft 2 so that tool change arm 3 turns clockwise 180 °, by the cutter aligned position positioned at the two ends of tool change arm 3 to be exchanged；4th step：Cam-type transmission case adjustment power transmission shaft is retracted and causes tool change arm to retract fastening in two ends cutter, and then is inserted respectively in cam-type transmission case and cutter holding head；5th step：Cam-type transmission case adjusts drive axis angle so that 30 ° of tool change arm rotate counterclockwise, tool change arm 3 returns to armed state.
By adopting such scheme, compared with prior art, it has technical effect that a kind of tilting tool change arm of the present invention：
1. a kind of tilting tool change arm solves well the cam-type cutter-exchange mechanism adopted in fixed column type horizontal Machining centers, and its tool change arm is in zero point（Stop position）With the defect of the interference problem of workpiece.
2. the cost of the movable device of tool magazine need not be increased, still using the mature Cam box mechanism of industry, dexterously solve when workpiece size is larger with the interference problem of tool change arm, while ensure that the speed and reliability of tool changing.
3. tool change arm can be adjusted as the case may be with the angle of horizontal direction, and Technological adaptability is more preferable.
Description of the drawings
Fig. 1 is a kind of overall structure diagram of the armed state of tilting tool change arm of the invention；
Fig. 2 is a kind of partial enlargement structural representation of tilting tool change arm of the invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention of greater clarity, with reference to instantiation and referring to the drawings, the present invention is described in more detail.It should be understood that these descriptions are simply exemplary, and it is not intended to limit the scope of the present invention.Additionally, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring idea of the invention.
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；The cam-type transmission case 1 is arranged on the side of cutter holding head 4, and is fixed in frame 6；The power transmission shaft 2 is arranged inside cam-type transmission case 1, one end connection tool change arm 3；The cutter holding head 4 is arranged on track-type facilities 5, and track-type facilities 5 are vertically installed in frame 6；
The cam-type transmission case 1 can adjust the rotational angle of take-off (propeller) shaft 2 and outreach, and then the attitude of adjustment tool change arm 3, and cam-type transmission case 1 also can transmit out cutter；
The two ends of the tool change arm 3 are provided with cutter draw-in groove 31, its be shaped as it is U-shaped, tool change arm 3 await orders attitude angle and horizontal direction in 30 °, the range of work in whole lathe and outside the appearance and size of workpiece.
