Description

Technical Field

[0001] This article belongs to the technical field of static balance cutting detection, and specifically relates to a combined device for static balance cutting detection of the motor housing of a new energy vehicle. Background Art

[0002] With the rapid rise of new energy vehicles in today's automotive industry, the market is expanding and demand is increasing. The quality and stability of motors, the core functional components of new energy vehicles, determine the stability of power control and driving safety of each new energy vehicle.

[0003] When a car is driving, the motor runs at high speed. There are strict requirements on the static balance, static imbalance and static imbalance angle of the motor itself (the technical specifications of the drawings are defined according to the actual use requirements). When the static balance is unqualified, the dynamic balance is definitely unqualified. When the vehicle is driving at high speed with this fault, the motor may be seriously worn and its service life may be reduced. In severe cases, traffic accidents such as bumps, loss of vehicle control, and rollover may occur.

[0004] In the current motor assembly process, after the motor is assembled, a static balancing test machine is used to test the motor's imbalance amount and imbalance angle. If qualified, the motor is passed to the next process. If unqualified, the edge of the motor casing is cut according to the measured imbalance amount and imbalance angle, and the motor's imbalance data is repeatedly measured until the imbalance amount and imbalance angle meet the requirements of the drawing before the motor is passed to the next process.

[0005] The static balancing cycle for a motor is 20 seconds, the chip correction cycle is 25 seconds, the clamping cycle is 15 seconds, and the inter-process transfer cycle is 5 seconds. More than 90% of motors require two static balancing tests and one cutting pass, for a total cycle time of 90 seconds. This cumbersome static balancing test and correction process has the following problems:

[0006] 1. Long cycle, low efficiency and high cost;

[0007] 2. The 1:1 ratio of equipment quantity is unreasonable;

[0008] 3. The site occupies a large area and the layout is unreasonable;

[0009] 4. The motor flatness correction cutting and transportation process result in poor cleanliness, affecting the motor performance and service life;

[0010] 5. The iron powder generated by the chips is not removed in time, resulting in large errors in static balance measurement, out of control of process quality, and affecting the performance and safety of the entire vehicle. Utility Model Content

[0011] In order to solve the above problems, this paper proposes a combination device for static balance cutting detection of new energy vehicle motor housing. The cutting detection combination device is arranged inside the base. The cutting detection combination device includes a balance detection seat, a rotating clamping claw assembly, a rotating cutting seat and a cutting machine. The motor housing is provided at the center of the upper surface of the balance detection seat. The balance detection seat is arranged on the right side of the base. The left side of the balance detection seat is provided with a rotating cutting seat in a horizontally aligned manner. A rotating clamping claw assembly is provided longitudinally between the rotating cutting seat and the balance detection seat. The upper surface of the rotating cutting seat is symmetrically provided with a shell clamping position. The cutting machine is provided vertically above the left side of the rotating cutting seat. The claw assembly includes a right-angle bracket, a circumferential rotating rod and a vertical lifting claw. The circumferential rotating rod is circumferentially rotatable and arranged below the front end of the right-angle bracket. The rotation center of the circumferential rotating rod is horizontally collinear with the center of the balance detection seat and the center of the rotating cutting seat. Vertical lifting claws are symmetrically arranged below both ends of the circumferential rotating rod. The spacing between the vertical lifting claws at both ends is the same as the spacing between the center of the balance detection seat and the center of the left shell of the rotating cutting seat. The right side of the base is adjacent to the balance detection seat and is provided with a feed and discharge opening, which improves production speed, reduces costs and increases efficiency, improves the accuracy of static balance, reduces errors, improves the quality stability and qualified rate of the production process, occupies less space, and reduces the number of operators.

[0012] The base is an outsourced protective base, which includes a device cover and a chassis. The chassis is vertically arranged at the four bottom corners of the cutting detection combination device, and the device cover is outsourced and arranged on the outside of the cutting detection combination device. A feed and discharge opening is provided on the lower right surface of the device cover. By arranging the feed and discharge opening on the right side of the device shell, efficient and fast direct single-person loading and unloading automated production is realized, which greatly improves production efficiency.

[0013] The balance detection seat is a static balance type electronic seat. A detection fulcrum is vertically provided in the center of the upper surface of the balance detection seat. The upper support of the detection fulcrum is connected to the bottom support of the motor housing. The balance detection seat is electrically linked to the rotating clamping jaw assembly. The balance of each motor housing is detected through the balance detection seat. If the detection fails, the rotating clamping jaw assembly is moved to the right for cutting balance processing.

[0014] The right-angle bracket is vertically and longitudinally arranged between the balance detection seat and the rotating cutting seat. The top front end of the right-angle bracket is vertically connected to the circumferential rotating rod through a rotating shaft. The center of the circumferential rotating rod is circumferentially connected with the right-angle bracket as a reference through a rotating shaft. Vertical lifting claws are vertically and vertically penetrated below the two ends of the circumferential rotating rod. The vertical lifting claws move up and down through the vertical guide column and are movable through the circumferential rotating rod. The bottom of the vertical lifting claw is provided with an inner and outer retractable shell clamp. The rotating clamp assembly can move the two motor casings that have been cut and need to be cut alternately in a segmented circular manner, and can also automatically detect the motor casing after cutting again, so as to ensure the effect after cutting.

[0015] The rotating cutting seat is a circular rotating position transfer seat. The center of the rotating cutting seat is fixedly connected to the bottom surface. The outer side of the rotating cutting seat is provided with a turntable that rotates in a circular manner. The upper surface of the turntable is symmetrically provided with shell clamps. The rotation limits of the shell clamps on both sides are provided at the left and right ends of the turntable. By rotating the cutting seat, a two-stage transfer cutting operation is realized. The motor housing that has been cut is rotated to the right, and the motor housing that needs to be cut is rotated to the left, thereby realizing a seamless automated production line effect.

[0016] The cutting machine is a vertical cutting machine. A cutting head is provided on the right side of the cutting machine, which moves vertically up and down. The cutting head is vertically arranged above the shell clamping position on the right side of the rotating cutting seat. The cutting machine is electrically controlled and linked to the rotating cutting seat. A negative pressure dust suction device is provided below the cutting machine and the rotating cutting seat. The motor housing is directly balanced by the vertical cutting machine, and the debris inside the device and after cutting is absorbed by the negative pressure dust suction device to prevent the debris from sticking to the motor housing.

[0017] Beneficial effects:

[0018] Improve production speed, reduce costs and increase efficiency; the original static balance detection and cutting process cycle was 90 seconds, now the cycle is 40 seconds;

[0019] Improve the accuracy of static balance and reduce errors; based on the static balance test data, digital automatic processing, PLC accurately controls the milling cutter cutting, which is more precise and stable. In addition, the equipment removes the cutting iron chips, there are no metal particles in the environment, and the static balance test value is also accurate.

[0020] Improve the quality stability and pass rate of the production process; static balance detection and cutting are clamped by high-precision mechanical claws in the special machine, which has good repeatability, takes up less space and reduces the number of operators.

[0021] By setting the material inlet and outlet openings on the right side of the device shell, efficient and fast automatic production with direct single-person loading and unloading is achieved, which greatly improves production efficiency.

[0022] The balance of each motor housing is tested through the balance detection seat. If it fails the test, the clamping jaw assembly is moved to the right for cutting and balancing.

[0023] The rotating clamping jaw assembly can alternately move the two motor housings that have been cut and those that need to be cut in a segmented circular manner, and can also automatically inspect the motor housing after cutting to ensure the effect after cutting.

[0024] By rotating the cutting seat, a two-stage transfer cutting operation is achieved. The motor housing that has been cut is rotated to the right, and the motor housing that needs to be cut is rotated to the left, thereby achieving a seamless automated production line effect.

[0025] The motor housing is directly balanced by a vertical cutting machine, and the debris inside the device and after cutting is absorbed by a negative pressure dust suction device to prevent the debris from sticking to the motor housing. BRIEF DESCRIPTION OF THE DRAWINGS
