Abstract
The utility model relates to a novel electromagnetic chuck, which is characterized in that a coil frame is sleeved on the periphery of a shaft, retaining disks in matching use are arranged on one end surface of the coil frame, a connector base is connected onto one side of the coil frame, a coil is wound on the coil frame, and a positioning sleeve is mounted in the middle of the shaft and fixed onto the shaft through a bolt. The novel electromagnetic chuck not only can be directly connected with a lathe spindle, but also can match with a chuck in use. After a safety power supply is switched on, the novel electromagnetic chuck can stability absorb disk-shaped workpieces made of steel and iron. Moreover, when the lathe spindle rotates, the workpieces can rotate together with the lathe spindle, and the part (the coil frame) of the portion, capable of generating magnetic force, of the novel electromagnetic chuck can keep relatively static. The novel electromagnetic chuck is a novel universal lathe clamping device, particularly applicable to processing the disk-shaped workpieces, and has the advantages of safety, reliability, rapid clamping, simple and convenient operation, low production cost, convenient maintenance and capability of effectively reducing labor intensity and improving work efficiency.
Description
[technical field]
The utility model belongs to the general clamping device technique of lathe kind equipment field, relates to a kind of electromagnet chuck that is mainly used in processing disc-shaped (as gear) class workpiece.
[background technology]
The lathe kind equipment all is the most frequently used and indispensable in any machined enterprise.No matter be engine lathe, hydraulic semi-automatic lathe, or numerically controlled lathe, basic structure all is that a connecting flange is installed on lathe spindle, chuck is contained on the connecting flange, by the chuck clamping workpiece again.According to the serviceability of chuck, its effect is surely rotated workpiece clamp with lathe spindle exactly with one heart.If promptly a kind of anchor clamps can firmly fix workpiece, rotate with one heart with lathe spindle, just met the demands.The most frequently used is scroll chuck, and the scroll chuck clamping workpiece is to dismantle workpiece and open chuck again energetically with the afterburning locking of chuck key by artificial, repeats dismounting, and labour intensity is big, and efficient is low; What hydraulic semi-automatic lathe was used is the wedge shape power chuck, is hydraulic pressure, the therefore hydraulic system that must form by hydraulic oil container and Hydraulic Elements, fluid pressure line, and the structure more complicated, noise is big, the cost height; General Digit Control Machine Tool adopts electric chuck, though advanced, laborsaving, be out of order easily, cost is also high, and maintenance is inconvenient.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of electromagnet principle of utilizing, can directly be linked together with lathe spindle, again can with the supporting use of chuck, electromagnet chuck with energy-conservation, efficient and benefit of safety.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electromagnet chuck, outside at axle is set with bobbin, end face at bobbin is provided with matching used block plate, side at bobbin is connected with junction block, on bobbin, installed around coil, positioning sleeve is equipped with at middle part at axle, and this positioning sleeve is by being bolted on the axle.Described axle is a pyramidal structure.
Described axle is contained in the bearing block, and bearing is housed in the bearing block.Be provided with spacer between the described bearing.Between described bobbin and the axle shaft block ring is housed.One side of described bobbin is provided with holddown groove.
The beneficial effects of the utility model are: can directly be linked together with lathe spindle, or with the supporting use of chuck, (annotate: supply voltage is a safe voltage after connecting power supply, promptly be lower than 36V), can inhale the disk type work of steel, iron class (or other magnetizable material) steady, and when lathe spindle rotated, workpiece also can rotate together, and its part (bobbin) that can produce the magnetic force part can keep static relatively; Be the general clamping device of a kind of novel lathe, be specially adapted to dish type class workpiece processing, have safe and reliable, quick-clamping, easy and simple to handle, can reduce labour intensity effectively, improve work efficiency, production cost characteristics low and easy to maintenance.Can remedy the deficiency of scroll chuck, hydraulic power chuck, electric chuck, have energy-conservation, efficient, safe advantage.
[description of drawings]
Fig. 1 is a structural representation of the present utility model; Structural representation when Fig. 2 is the utility model behaviour in service; Fig. 3 is the structural representation of bobbin described in the utility model.
Among the figure: 1-bobbin, 2-block plate, 3-bearing, 4-axle, 5-positioning sleeve, 6-bolt, 7-workpiece, 8-spacer, 9-coil, 10-junction block, 11-shaft block ring, 12-holddown groove.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1 to Fig. 3, a kind of electromagnet chuck, axle 4 is contained in the bearing block, and the pyramidal structure of axle 4 is to be used for linking to each other with the main shaft inner cone or by the tapered sleeve transition, bearing 3 being housed in the bearing block, is provided with spacer 8 between bearing 3; Be set with bobbin 1 in the outside of axle 4, side 1 at bobbin is connected with junction block 10, has installed around coil 9 on bobbin 1, line footpath, the number of turns that coil 9 is different according to different bobbin 1 required designs, but keep voltage constant, promptly all coils frame 1 all uses same power supply; At the middle part of axle 4 positioning sleeve 5 is housed, one end of positioning sleeve 5 is fastening by bolt 6 with axle 4, and the other end and workpiece 7 endoporus interference fits are equivalent to the mandrel of workpiece 7, not only workpiece 7 can be located fast, and can prevent that workpiece 7 from throwing away because of centrifugal force when rotating at a high speed.Workpiece 7 is adsorbed on the block plate 2 by magnetic force; Described bobbin 1 and axle are equipped with shaft block ring 11 between 4, are provided with matching used block plate 2 in a side of bobbin 1, are provided with holddown groove 12 in a side of bobbin 1.
Operation principle of the present utility model is: axle 4 is linked together with the lathe spindle endoporus, simultaneously can drive block plate 2 by key again, the small stair and the bearing inner race of block plate 2 are close together, maintain a certain distance s with bobbin, bobbin 1 is fixed, make it when lathe spindle rotates, keep motionless, the closing coil power supply, make block plate 2 produce powerful magnetic force, inhale workpiece 7 steady, the starting lathe makes main axis rotation, drive axle 4, block plate 2, workpiece 7 and rotate together, just can the smear metal excircle of workpiece, end face.Deenergization just can take off workpiece 7 easily, and is very easy, quick.According to hole size in the workpiece, select the positioning sleeve 5 of different size for use, workpiece 7 also can have step, also can not have step, and the range of work is very wide.The utility model can directly connect with lathe, also can with the supporting use of lathe chuck; Utilize the electromagnet principle, thereby metastable power supply must be arranged, and could work after the energising; A part of the present utility model can be put rotation simultaneously with lathe spindle, and another part transfixion relatively; Can be steady after the energising with the disk type work of steel, iron class (or other magnetizable material) being inhaled, can not throw away during the workpiece rotation because of centrifugal force.The utility model is the general clamping device of a kind of novel lathe, is specially adapted to dish type class workpiece processing, have safe and reliable, quick-clamping, easy and simple to handle, can reduce labour intensity effectively, improve work efficiency, cost is low, easy to maintenance simultaneously.Can remedy the deficiency of scroll chuck, hydraulic power chuck, electric chuck, have novel, practical, energy-conservation, efficient, safe advantage.
