Abstract

The utility model discloses an internal water jacket lathe clamping fixture structure, which comprises a chunk, a shaft and a concave key. The chunk also comprises a locking mechanism; the shaft is provided with two symmetrical long key slots; the key slots and the concave key are connected with the chunk together to ensure that the chunk is positioned in the axial direction of the shaft and the chunk in the axial direction can slide in the key slot of the shaft along with the concave key; and the chunk is locked by the locking mechanism when the chunk slides to the proper position. The utility model has the advantages that: a, good universal performance, b, simple operation and accurate positioning, and c, improvement on processing precision.

Description

A kind of lathe mould with internal water jacket structure
Technical field
The utility model relates to field of machining, relates in particular to a kind of electric machine stand and makes the field.Be a kind of lathe mould with internal water jacket structure specifically.
Background technology
When processing support inner water sleeve, need to adopt lathe mould (hereinafter to be referred as tire) processing, general tire is the axle of a regular length, each fixes a cover three-jaw universal chuck two ends, support the internal diameter of firm inner water sleeve with claw, utilize top axle is fixed on the lathe to process again, tire is to utilize the moving radially of claw of scroll chuck to adapt to the water jacket diameter variation diametrically.Because the motor of producing is wide in variety, the length of support is just different, thereby the length difference of inner water sleeve, so the inner water sleeve of each length of interval all needs to be equipped with the axle of respective length, this just need manufacture the tire of a lot of different lengths, increased production cost, when producing same kind in enormous quantities, if the tire lazy weight has a strong impact on the production cycle; In addition, because tire is wide in variety, quantity is big, usually is to have stacked a lot of tires in the frock storehouse, is difficult to find a kind of tire of suitable length, needs the personal management, and this has increased management cost again.
The utility model content
At the problems referred to above, the purpose of this utility model is the tire generalization, reduces the quantity of tire, the cost of reduction frock and easy to use, and satisfy the needs of producing in batches.And on technological layer, can change a plurality of location benchmark of existing inner water sleeve assembly welding machining processes into one, on existing machined capability foundation discussion, significantly improve machining accuracy.
To mainly be the length that can change tire arbitrarily, enable to adapt to the water jacket of different length,, change the distance between two chucks on a major axis, just can satisfy the needs of different length water jacket if we allow chuck move arbitrarily the tire generalization.Concrete scheme of the present utility model is:
A kind of universal lathe mould with internal water jacket comprises chuck 2, axle 3 and matrix key 4, and chuck 2 also comprises retaining mechanism 1; Processed the long keyway of two symmetries on the described axle 3, utilize described keyway and matrix key 4 that axle 3 and chuck 2 are linked together, chuck 2 is upwards located in the footpath of axle 3, chuck 2 can slide on axle 3 the keyway along with matrix key 4 one coexists in the axial direction, when sliding into suitable position, utilize described retaining mechanism, chuck is locked.
Described retaining mechanism 1 is made up of stop nut 11, clamp nut 12, ringfeder 13 and placenta 14; Placenta 14 use Bolt Connection with chuck 2, and 14 of clamp nut 12 and placentas are threaded, and the maximum gauge of ringfeder (13) is greater than clamp nut (12) minimum diameter, ringfeder 13 servo-actuateds when screwing clamp nut 12 with assurance; Ringfeder 13 front end external diameters change from small to big, and axle 3 inserts in the ringfeder 13, to guarantee when screwing clamp nut 12, ringfeder 13 is along with the promotion of clamp nut 12 is moved in placenta together, ringfeder 13 is by the extruding of the inclined-plane of placenta 14, and diameter then dwindles, and ringfeder 13 just is fixed on the surface of axle 3 firmly.Screw stop nut 11 again, retaining mechanism has just been finished locking like this.
For obtaining better technique effect, described placenta 14 has identical slope with ringfeder 13 corresponding masks.
The good effect of advantage of the present utility model and generation
The universal performance that advantage: a is good, simple to operate, the accurate positioning of d, c improves machining accuracy.
Effect: can save a large amount of tires
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the retaining mechanism schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model comprises chuck 2, axle 3 and matrix key 4, and chuck 2 also comprises retaining mechanism 1; Processed the long keyway of two symmetries on the described axle 3, utilize described keyway and matrix key 4 that axle 3 and chuck 2 are linked together, chuck 2 is upwards located in the footpath of axle 3, chuck 2 can slide on axle 3 the keyway along with key 5 one coexists in the axial direction, when sliding into suitable position, utilize described retaining mechanism, chuck is locked, so reality chuck on axle, move arbitrarily, adapt to the water jacket of different length.
Described retaining mechanism is made up of stop nut 11, clamp nut 12, ringfeder 13 and placenta 14; Placenta 14 use Bolt Connection with chuck 2, and 14 of clamp nut 12 and placentas are threaded, and the maximum gauge of ringfeder (13) is greater than clamp nut (12) minimum diameter, ringfeder 13 servo-actuateds when screwing clamp nut 12 with assurance; Ringfeder 13 front end external diameters change from small to big, and axle 3 inserts in the ringfeder 13, to guarantee when screwing clamp nut 12, ringfeder 13 is along with the promotion of clamp nut 12 is moved in placenta together, ringfeder 13 is by the extruding of the inclined-plane of placenta 14, and diameter then dwindles, and ringfeder 13 just is fixed on the surface of axle 3 firmly.Screw stop nut 11 again, retaining mechanism has just been finished locking like this.
For obtaining better technique effect, described placenta 14 has identical gradient with ringfeder 13 corresponding masks.
Be the different chuck of the diameter that is installed, make axle general, we can install axle sleeve additional in the chuck hole, make the aperture of the different chuck of the diameter that is installed identical, have so just solved the common question of axle.
