Description

Technical Field

[0001] The utility model relates to the technical field of motor shell processing, in particular to a slotting machine. Background Art

[0002] For grooving the inner hole, it is generally necessary to use a pull rod to drive the grooving tool to broach the inner hole of the workpiece multiple times. In order to improve the processing efficiency, the applicant proposed a solution to replace the grooving tool with a rotating circular saw to groove the inner hole of the motor housing.

[0003] However, during the processing, it was found that the rotary circular saw was severely worn after repeated use. The reason is that since the circular saw cuts in the inner hole of the motor housing, poor heat dissipation causes heat accumulation, and the motor housing made of aluminum alloy is prone to deformation under high temperature conditions. The deformed housing squeezes the circular saw, which causes wear problems on the surface of the circular saw.

[0004] In view of this, the applicant further improved the original solution by using a compressor to release compressed air to drive the circular saw, thereby improving the heat dissipation effect of the device when grooving. Utility Model Content

[0005] To this end, the utility model provides a slotting machine to solve the problem in the prior art that the heat accumulation during slotting by a circular saw causes tool wear.

[0012] Furthermore, the transmission device is a transmission belt, and the steering gear drives the slotter to rotate on the cantilever beam through the transmission belt.

[0013] Furthermore, the steering gear is connected to the end of the cantilever beam through a telescopic rod.

[0015] An air guide housing, with a pneumatic circular saw installed at the tail end and a rotary joint installed at the head end, wherein the compressor is connected to the air guide housing through the rotary joint and releases air flow to drive the pneumatic circular saw to rotate;

[0016] The pulley is fixedly sleeved on the rotary joint, and the pulley is connected to the steering gear through a transmission belt.

[0017] Furthermore, the pneumatic circular saw comprises:

[0018] The saw blade has a pair of impellers symmetrically mounted on the front and back sides;

[0019] The rotating shaft is arranged through the center of a pair of impellers, and two ends of the rotating shaft are rotatably arranged in the air guide shell.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-4 The slotting machine disclosed in the utility model mainly drives the pneumatic circular saw 8 by pneumatic drive instead of the previous mechanical drive mode, and the specific description is as follows:

[0035] like Figure 1The device mainly includes a displacement device 1, a cantilever beam 3 and a slotter 5, wherein the displacement device 1 is a transmission device with two cylinders or lead screw structures arranged orthogonally, which can drive the cantilever beam 3 to move in the upward, downward, left and right directions, and the cantilever beam 3 is used to install the slotter 5 and the steering gear 7, wherein the steering gear 7 and the slotter 5 are respectively located at the two ends of the cantilever beam 3, and the steering gear 7 is connected to the slotter 5 through the transmission device 4, and drives the slotter 5 to rotate. In this embodiment, the slotter 5 is vertically and rotatably arranged at the end of the cantilever beam 3, and a pneumatic circular saw 8 is installed at the bottom of the slotter 5, and the top is connected to the compressor installed on the top of the displacement device 1. The compressor outputs a strong airflow to the outside to drive the pneumatic circular saw 8 to rotate at a high speed, and the pneumatic circular saw 8 is used to slot the inside of the motor housing.

[0036] In this embodiment, the servo 7 is a stepper motor, and the transmission device 4 is a transmission belt. The transmission device 4 can be used to transmit the torque of the servo 7 to the slotter 5. Since the axial torque on the slotter 5 is small, the use requirements can be met from an economic cost perspective by using a belt drive transmission method. At the same time, the equipment maintenance cost and maintenance difficulty can be effectively reduced. When in use, the servo 7 drives the slotter 5 to rotate, and slots can be made at multiple angles inside the motor housing without adjusting the position of the workpiece, thereby significantly improving the processing accuracy of the slotting.

[0037] In this embodiment, the steering gear 7 is connected to the end of the cantilever beam 3 through a telescopic rod, wherein the length of the telescopic rod can be automatically adjusted and fixed. Moreover, since the telescopic rod is connected to the steering gear 7, the linear distance between the steering gear 7 and the slotter 5 can be changed by adjusting the telescopic rod, thereby tightening the belt to prevent the belt from slipping and improving the transmission efficiency.

[0038] In a specific embodiment disclosed in the utility model, the slotter 5 includes an air guide housing 51 and a pulley 52, wherein a pneumatic circular saw 8 is installed at the tail end of the air guide housing 51, and the pneumatic circular saw 8 is used to process the motor housing.

A pulley 52 is fixedly arranged on the rotary joint 53, and the pulley 52 is coaxially arranged with the rotary joint 53, and the pulley 52 is connected to the steering gear 7 through a transmission belt, so that the steering gear 7 can drive the rotary joint 53 to rotate through the pulley 52. ​​Furthermore, an encoder is also installed on the rotary joint 53, and the encoder converts angular displacement or linear displacement into an electrical signal, thereby determining the rotation position of the air guide housing 51.

[0039] In this embodiment, if Figure 2The pneumatic circular saw 8 includes a saw blade 81, an impeller 82 and a rotating shaft 83, wherein the saw blade 81 is in the shape of a disc, and a pair of impellers 82 are symmetrically installed on the front and back surfaces of the saw blade 81, and a rotating shaft 83 is provided through the center of the impeller 82, and both ends of the rotating shaft 83 are rotatably arranged in the air guide shell 51. The air guide shell 51 can act on the impeller 82 along the rotating shaft 83 released by the compressor 2, thereby driving the impeller 82 and the saw blade 81 to rotate, and the outflowing airflow flows out along the surface of the saw blade 81 and acts on the motor housing, thereby significantly improving the heat dissipation effect in the motor housing, reducing the temperature of the motor housing, and thereby suppressing the deformation problem caused by the heat of the motor housing.

[0040] In this embodiment, if Figure 4 The air guide shell 51 includes a main body 511, a diverter tee 514 and a bearing seat 513, wherein a pair of air guide grooves 512 are arranged inside the main body 511, and the adapter 53 is connected to the pair of air guide grooves 512 through the diverter tee 514. At the same time, the air guide groove 512 introduces the airflow to the position of the bearing seat 513. The bearing seat 513 is arranged at the end of the main body 511 and is connected to the pair of air guide grooves 512. The bearing seat 513 is suitable for introducing the airflow to the impeller 82, thereby achieving the effect of driving the saw blade 81 to rotate at high speed.
