[0004] When in use, loosen the nut on the first connecting rod, turn the abutment block to the center side of the mounting disk, pass the motor housing to be processed through the mounting disk and put it on the sleeve, then turn the abutment block back to the side away from the center of the mounting disk, tighten the nut on the first connecting rod, and under the action of the oil cylinder, the abutment block presses the motor housing against the mounting plate to fix the motor housing, and drills the motor housing through the first drilling mechanism.

[0005] However, in the process of drilling the motor shell using the motor shell processing center, only one motor shell can be processed after one clamping, and the production efficiency is low. Summary of the invention

[0006] In view of this, an object of the present invention is to provide a high-efficiency machining center for motor housings, which can process multiple motor housings after one clamping and has the advantage of high production efficiency.

[0007] In order to solve the above technical problems, the technical solution of the present invention is: an efficient machining center for a motor casing, comprising a frame, a clamping assembly arranged on the frame for clamping the motor casing, and a drilling assembly arranged on the frame for drilling holes in the motor casing, wherein the clamping assembly is located below the drilling assembly, and the clamping assembly comprises a guide rail fixedly arranged on the frame, a material storage frame slidably arranged on the guide rail, and a driving mechanism for driving the material storage frame, wherein a storage trough for placing multiple motor casings is provided on the top of the material storage frame.

[0008] Through the above technical solution, a processing plane and a supporting plane are symmetrically arranged at the side wall of the motor housing to be processed, and the processing plane and the supporting plane are parallel to each other. When in use, the processing plane needs to be drilled.

[0009] The first step is to place multiple motor housings into the storage tank in sequence. The second step is to rotate the motor housing so that the processing plane of the motor housing faces the side of the drilling assembly, so that the support plane of the motor housing contacts the bottom surface of the storage tank. The third step is to control the storage frame to move through the driving mechanism so that the motor housing at the front end of the storage frame moves to the bottom of the drilling assembly. The fourth step is to drill the processing plane of the motor housing through the drilling assembly. The fifth step is to control the storage frame to move forward through the driving mechanism so that the next motor housing moves to the bottom of the drilling assembly. The sixth step is to drill the motor housing through the drilling assembly. The seventh step is to repeat the fifth and sixth steps until all the motor housings are drilled. When using the above-mentioned high-efficiency machining center for motor housings, multiple motor housings can be drilled with only one clamping, and the production efficiency is high.

[0010] Preferably, the driving mechanism includes a screw rod rotatably connected to the frame, a driving motor fixedly connected to the frame for driving the screw rod, and a nut seat fixedly connected to the bottom of the material storage frame, the screw rod passes through the nut seat, and the screw rod is threadedly connected to the nut seat.

[0011] According to the above technical solution, since the screw rod is threadedly connected to the nut seat, when the drive motor drives the screw rod to rotate circumferentially, the screw rod can drive the material storage frame to move through the nut seat. By changing the rotation direction of the output shaft of the drive motor, the material storage frame can be driven to move in the opposite direction.

[0012] Preferably, the clamping assembly further comprises a plurality of partitioning mechanisms arranged at the bottom of the material storage trough, a positioning chamber is formed between two adjacent partitioning mechanisms, and when the motor housing is placed into the positioning chamber, the two partitioning mechanisms clamp the motor housing.

[0013] Through the above technical solution, when the motor housing is placed into the positioning chamber, the partition mechanisms on both sides can clamp the motor housing to limit the position of the motor housing, making the drilling process smoother.

[0014] Preferably, the separation mechanism comprises a positioning fork and positioning rubbers symmetrically arranged on both sides of the positioning fork.

[0015] According to the above technical solution, since the friction coefficient of the positioning rubber is relatively large, after the positioning rubber and the motor housing are pressed tightly, the motor housing can be effectively limited, so that the motor housing is not easy to move. Furthermore, since the positioning rubber is relatively soft, after the positioning rubber and the motor housing are pressed tightly, the motor housing can be effectively protected, so that the motor housing is not easy to be damaged.

[0016] Preferably, a side wall of the positioning rubber is provided with an arc surface, and the arc surface is used to be in close contact with the outer side of the motor housing.

[0017] Through the above technical solution, the side wall of the positioning rubber is provided with an arc surface, which can increase the contact area between the positioning rubber and the motor housing, and enhance the limiting effect of the positioning rubber on the motor housing.

[0018] Preferably, a sliding groove is provided at the bottom of the material storage frame, the positioning fork is slidably connected in the sliding groove, an actuator cylinder is provided inside the sliding groove, and a piston rod of the actuator cylinder is connected to the positioning fork.

[0019] Through the above technical solution, when the motor housing needs to be placed inside the storage tank, the positioning fork is controlled by the cylinder to slide into the sliding groove, so that the positioning fork is not easy to hinder the placement of the motor housing. When the motor housing has been completely placed in the storage tank, the positioning fork is controlled by the cylinder to slide out of the sliding groove to limit the motor housing.

[0020] Preferably, the clamping assembly further comprises a flipping mechanism arranged in the material storage frame, and the flipping mechanism is used to contact with the outer side of the motor housing and drive the motor housing to rotate circumferentially.

[0021] Through the above technical solution, after the motor housing is placed in the material storage tank, the motor housing is controlled to rotate circumferentially by using a flipping mechanism to turn the processing plane of the motor housing to the side of the drilling assembly. The method of flipping the motor housing by using a flipping mechanism instead of manually flipping the motor housing improves the automation level and processing efficiency of the machining center to a certain extent.

[0022] Preferably, the flipping mechanism includes a response member and a trigger member, the response member is arranged at the side wall of the positioning fork to drive the motor housing to rotate circumferentially, and the trigger member is arranged between the two partition mechanisms to control the opening and closing of the response member.

[0023] Through the above technical solution, when the supporting plane of the motor housing does not touch the bottom of the material storage tank, the trigger member controls the response member to open, and the response member controls the motor housing to rotate circumferentially. When the supporting plane of the motor housing touches the trigger member, the trigger member controls the response member to close, and the motor housing stops rotating. At this time, the processing plane of the motor housing faces the side of the drilling assembly.

[0024] Preferably, a through hole is provided through the positioning rubber, the response member is located in the through hole, and the response member includes a mounting seat fixedly connected to the side wall of the positioning fork, a roller rotatably connected to the middle of the mounting seat, and an actuator motor arranged on the side wall of the mounting seat to drive the roller to rotate, and one side of the roller protrudes from the through hole.

[0025] Through the above technical solution, when the motor is turned on, the roller can be controlled to rotate circumferentially. At the same time, the roller can drive the motor housing to rotate circumferentially to adjust the motor housing.

[0026] Preferably, a movable groove is provided at the side wall of the positioning fork, the positioning rubber is slidably connected in the movable groove, a return spring is provided in the movable groove, the return spring is used to drive the positioning rubber to press against the outer side of the motor housing, a receiving groove is provided at the bottom of the storage trough, the trigger member includes a trigger plate, a support spring, an elastic rope and a contact switch, the trigger plate is slidably connected in the receiving groove, the upper end of the support spring is connected to the trigger plate, the lower end of the support spring is connected to the bottom surface of the receiving groove, one end of the elastic rope is connected to the trigger plate, the other end of the elastic rope passes through the positioning fork and is connected to the positioning rubber, and the contact switch is provided at the bottom surface of the trigger plate to contact the bottom surface of the receiving groove.

[0027] Through the above technical solution, when the motor housing is placed into the positioning chamber, if the processing plane of the motor housing is not facing the side of the drilling assembly, the motor housing will gradually press the trigger plate into the storage groove. At the same time, the trigger plate can drive the positioning rubber to slide into the movable groove through the elastic rope to release the limit on the motor housing. When the contact switch on the bottom surface of the trigger plate contacts the bottom surface of the storage tank, the contact switch controls the execution motor to turn on to control the motor housing to rotate circumferentially. When the processing plane of the motor housing faces the side of the drilling assembly, the support plane of the motor housing contacts the bottom surface of the storage tank, the trigger plate moves up under the action of the support spring, the contact switch separates from the bottom surface of the storage tank, and the execution motor stops working. At the same time, the positioning rubber moves up under the action of the reset spring and contacts the outer side of the motor housing to limit the motor housing. BRIEF DESCRIPTION OF THE DRAWINGS
