Description
Technical Field
The utility model relates to the field of machinary, specifically be a positioner of ER collet chuck installation cutter.
Background
The ER collet chuck is a cylindrical fixture, also called ER collet chuck, used for fixing a drilling and tapping tool or a milling tool on a main shaft of a drilling, tapping, milling machine or a machining center. The fixing and locking device can also be used for fixing and reinforcing parts needing to be reformed and processed. The ER collet chuck has the advantages of large clamping force, wide clamping range and good precision. The method is widely used for processing boring, milling, drilling, tapping, grinding, carving and the like. The ER chuck is one of spring chucks and is generally used for matching with a numerical control knife handle. The standard ER collet chuck is not positioned during installation, the depth of a cutter cannot be controlled, and the extension length of the same cutter in the same type can be greatly different during installation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a positioner of ER collet installation cutter to the standard ER collet that provides in solving above-mentioned background art does not have the location when the installation, the degree of depth uncontrollable of cutter, the same long cutter of same money can vary greatly problem in the installation extension.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a positioner of ER collet installation cutter, includes rotor and end mill, the sword groove has been seted up at the middle part of rotor one end, the opening part in sword groove passes through collet and end mill's middle part fixed connection, the one end fixedly connected with adjustable positioning screw that end mill arranged in sword inslot portion, the sword groove is kept away from open-ended one end and is seted up the movable orifice, the one end fixedly connected with in movable orifice adjusts the lock screw, the screw threaded connection that the one end and the adjustable positioning screw one end of adjusting the lock screw were seted up.
As an optimized technical scheme of the utility model, the spring chuck has the nut with the junction threaded connection of rotor.
As an optimized technical scheme of the utility model, the one end and the movable hole interlude of adjustable positioning screw are connected.
Compared with the prior art, the beneficial effects of the utility model are that: the positioning device is simple and reasonable in structure, the end milling cutter is inserted into the rotor after the spring chuck is installed, then the nut is screwed to fix the end milling cutter, the stability and the safety of the work of the end milling cutter are guaranteed under the action of the spring chuck, the position of the end milling cutter is fixed, the rotor is rotated, the adjusting and locking screw is driven to rotate, the adjustable positioning screw is driven to move along the movable hole, under the positioning of the adjustable positioning screw, the cutter installation length is unchanged, and the time waste caused by cutter setting on a machine is reduced.
Drawings
Fig. 1 is a sectional view of the present invention.
In the figure: 1. a rotor; 2. an end mill; 3. a collet chuck; 4. a nut; 5. an adjustable positioning screw; 6. adjusting the locking screw.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1, the utility model provides a positioner of ER collet chuck installation cutter, including rotor 1 and end mill 2, the sword groove has been seted up at the middle part of rotor 1 one end, and the opening part in sword groove passes through collet chuck 3 and end mill 2's middle part fixed connection, and end mill 2 arranges the adjustable positioning screw rod 5 of the one end fixedly connected with of sword inslot portion in, and the sword groove is kept away from open-ended one end and has been seted up the movable hole, and the one end fixedly connected with in movable hole adjusts lock screw 6, adjusts the screw threaded connection that the one end of lock screw rod 6 and 5 one end of adjustable positioning screw were seted up.
Preferably, a nut 4 is screwed to a joint between the collet 3 and the rotor 1, the end mill 2 is inserted after the collet 3 is fitted into the rotor 1, and the end mill 2 is fixed by screwing the nut 4.
Preferably, one end of the adjustable positioning screw rod 5 is inserted into the movable hole, so that the stability of the adjustable positioning screw rod 5 in the movement process is improved.
When specifically using, the utility model relates to a positioner of ER collet chuck installation cutter inserts end mill 2 after 3 to the spring chuck of packing into on the rotor 1, then it fixes to end mill 2 to spin up nut 4, the stability and the security of 2 jobs of end mill are guaranteed to the effect through spring chuck 3, the position of fixed end mill 2, rotary rotor 1, it is rotatory to drive regulation lock solid screw 6, thereby it removes along the activity hole to drive adjustable positioning screw 5, under adjustable positioning screw 5's location, can realize that cutter installation length is unchangeable, reduce the tool setting and give and lead to the fact the waste in time for the accent machine.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
