Abstract
The utility model discloses a lathing clamp for an internal spigot of a casing of a motor. The lathing clamp comprises a top rod handle, a top rod, an expansion body and a bolt. The top rod is a hollow round cone body. The top rod handle is disposed under the round bottom of the top rod and is connected with the top rod to be a whole body. The expansion body is a hollow cylinder, and the round top of the top rod is in contact with the inner wall of the expansion body. The bolt passes through holes from transverse planes of the top rod and the expansion body, and is compacted by a nut and a pad. When the clamp is in use, the bolt is firstly placed into the top rod, the top rod handle is made to match the top rod, and the top rod handle and the top rod are firmly welded through electric welding; then the top rod handle is clamped by a lathe three-pawl clamping disc, and a motor is sleeved on the top rod to allow the round bottom of the top rod to be in contact with the inner surface of a stator punching sheet; and finally the expansion body is sleeved on the bolt, and the nut and the pad are tightened, so that the expansion body is in contact with the inner surface of the stator punching sheet. In this way, an internal spigot of a casing of a motor can be lathed.
Description
Technical field
The utility model relates to the vehicle clamper of processing motor casing inner stopper.
Background technology
Motor is after the assembling of stator and casing is complete, and certain distortion can occur the inner stopper of its casing.Now, if directly at the casing stop portion, load onto rear end cap, the projecting surface that can not guarantee rear end cap contacts with the inner stopper of casing, can cause the axiality of whole motor poor, thereby affect the performance of motor.Therefore motor stator and casing assemble complete after, need to be processed the inner stopper of casing, thereby be guaranteed the axiality of whole motor, the performance of lifting motor.The inner stopper processing of the motor that existing 140 series are above is all to use solid mandrel, and solid mandrel adopts particulate metal material to be made.Because the weight of motor itself is just very heavy, if add a longer plug, add so man-hour, the weigh object of 50Kg of the upper and lower lift to move of workman, waste time and energy, and operating efficiency is also very low.And if process 180 even during the motor of 260 series, a people may not bring up to lathe to workpiece, just needs two workmans, cost increases.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of vehicle clamper, and its weight is lighter, can realize like a cork the processing to the motor casing inner stopper.Simultaneously, this fixture can be increased work efficiency, and reduces labor strength.
The vehicle clamper of the utility model motor casing inner stopper is characterized in that: it comprises the excellent handle in top, top rod, expander, bolt; The top rod is the Rotary-table of hollow, pushes up excellent handle and is arranged on excellent round platform bottom, top, with the top rod, is connected in aggregates; Expander is the cylinder of hollow, pushes up excellent round platform top and contacts with the inwall of expander; Bolt passes from the hole of both end faces, and by nut, pad tight.
While using this fixture, first bolt is put into to the top rod inner, then will push up excellent handle and match with the top rod, with electric weld handle, both weld solid; Then with the lathe three-claw chuck, clamp the excellent handle in top, then motor is enclosed within to the top rod upper, make to push up excellent round platform bottom and contact with the inner surface of stator punching; Finally expander is enclosed within on bolt, fastening screw nut, pad, make expander contact with the inner surface of stator punching, just can carry out the Vehicle Processing of motor case seam.
Because top is excellent and expander is all the part of hollow, so the weight of whole fixture is lighter, can realize like a cork the processing to the motor casing inner stopper.Simultaneously, the upper and lower lift to move of whole fixture is convenient light and handy, can greatly increase work efficiency, and reduces workman's labour intensity.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model vehicle clamper.
Fig. 2 is the front view of expander.
Fig. 3 is the left view of Fig. 2.
Embodiment
As can be seen from Figure 1, the vehicle clamper of the utility model motor casing inner stopper, it comprises the excellent handle 1 in top, top rod 4, expander 5, bolt 7.
Wherein, the Rotary-table that top rod 4 is hollow, push up the round platform bottom that excellent handle 1 is arranged on top rod 4, with top rod 4, is connected in aggregates.Wherein, the tapering of the round platform bottom of top rod 4 contacts with the inner surface of stator punching 3.For both are contacted better, the tapering of the round platform bottom of top rod 4 is 1:1000.
From Fig. 2, Fig. 3, expander 5 is cylinders of hollow, and the round platform top of top rod 4 contacts with the inwall of expander 5.Expansion effect while for the round platform top that makes top rod 4, propping up expander 5 internal diameter is better, and a kind of optimal way as originally novel, have several uniform otch vertically from its top on the cylindrical shell of expander 5.
In this fixture, the method that top rod 4 and expander 5 all adopt hollow to make, alleviate overall weight, and bolt 7 is used for connecting this two parts, by screwing bolt 7, changes the distance between top rod 4 and expander 5.When top rod 4 enters into expander 5 the insides, make its expansion, then with motor stator punching 3 inside from touching jam-packed, thereby fix whole motor, be convenient to the inner seam A of its motor case 2 face is machined.After completion of processing, unscrew bolt 7, now top rod 4 and expander 5 separately, then take off motor from frock clamp.
After using this cover frock clamp, workman's operating efficiency has improved significantly.For example: for model, be the 130-10Nm-2000Rpm motor, its weight is 20Kg, adds this frock clamp, and total weight is less than 30Kg, and former fixture adds motor weight more than 40 Kg.Therefore before, the workman processes 30 at most in one day, and the workman can process 50 every day now, has improved widely operating efficiency.For example, while processing 180 serial motors, the total weight of motor and this fixture greatly more than 50Kg, and surpasses 50Kg with the weight of front motor and fixture, therefore uses this fixture both to improve output, has reduced again difficulty of processing.Use this sleeve clamp to carry out to motor case the axiality that inner stopper processing can improve motor shaft, within the coaxiality error of motor-shaft extending end is controlled to 0.005 ~ 0.01mm scope, the performance of motor is had a distinct increment.
