Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to an automatic machine tool for producing motor housings. Background Technology

[0002] In the motor manufacturing industry, the motor housing is an important component of the motor. Its processing quality and production efficiency directly affect the overall performance and production cost of the motor. Traditional motor housing production methods mostly rely on manual operation combined with simple mechanical processing equipment, which has problems such as low production efficiency, difficulty in ensuring processing accuracy, high labor costs, and high labor intensity. With the continuous development of industrial automation technology, although some production processes have been automated.

[0003] However, existing motor housing production equipment often suffers from defects such as single function, poor connection between processing steps, and insufficient automation, which cannot meet the needs of large-scale, high-quality motor housing production. Therefore, there is an urgent need to design an automatic motor housing production machine tool that integrates multiple processing functions and can achieve automated continuous production. Hence, an automatic motor housing production machine tool is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic machine tool for producing motor housings, which automates the motor housing production process, improves production efficiency and processing accuracy, and reduces production costs, thus solving the problem of the need for optimization of the existing device structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic production machine tool for motor housings, comprising a production line body, an internal feeding conveyor line, an internal unloading conveyor line, an internal three-axis gantry robot, an internal secondary positioning platform, an internal barcode scanning NG material channel, an internal laser marking machine, an external system control cabinet, an external machine tool body, and an external three-phase transformer.

[0006] Furthermore, the main body of the production line is provided with a blank buffer space and a finished product buffer space.

[0007] Furthermore, the specific model of the three-axis gantry robot is GAT-Z1-60. The X-axis moving speed of the three-axis gantry robot is 90m / min, the Y-axis moving speed is 30m / min, the Z-axis moving speed is 60m / min, and the reset and positioning accuracy of the three-axis gantry robot is ≤±0.05mm.

[0008] Furthermore, the barcode scanning NG material channel is located between the loading and unloading conveyor lines. The laser marking machine uses a fiber laser to output laser light. The effective marking range of the laser marking machine is not less than 110*110mm. The marking repeatability of the laser marking machine is ±0.005mm. The minimum character size of the laser marking machine is 0.2mm. The minimum line width of the laser marking machine is 0.01mm.

[0009] Furthermore, the system control cabinet is a central PLC controller, which uses a FANUC numerical control system internally. The system control cabinet is equipped with an HIMI display on the outside, and the three-axis gantry robot uses a handheld mobile operating box.

[0010] Furthermore, the specific model of the machine tool body is TT2500MS.

[0011] Beneficial effects

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This automated machine tool for producing motor housings, equipped with a three-axis gantry robot and a feeding conveyor line, can feed raw materials into the machine tool body for processing. The finished products are then stored in a temporary storage table and marked with a laser marking machine. Simultaneously, the workpieces are scanned and confirmed by a barcode scanner.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 An automatic production machine tool for motor housings includes a production line body 1, an internal feeding conveyor line 2, an internal unloading conveyor line 3, an internal three-axis gantry robot 4, an internal secondary positioning table 5, an internal barcode scanning NG material channel 6, an internal laser marking machine 7, an external system control cabinet 8, an external machine tool body 9, and an external three-phase transformer 10.

[0019] Specifically, such as Figure 1 As shown, the raw materials to be processed are manually placed in the feeding hopper in a specified direction. The hopper adopts a roller conveyor and can store multiple batches of raw materials. The feeding is assisted by a cantilever crane to ensure that the raw materials are placed neatly, which is convenient for subsequent gripping by the gantry robot. The feeding hopper has a positioning function, and the positioning device can be quickly replaced to adapt to the clamping requirements of pistons of different specifications.

[0020] Specifically, such as Figure 1 As shown, the three-axis gantry robot 4 uses a SUNK gripper to pick up the blank from the blank buffer position and move it to the secondary positioning stage 5. The three-axis gantry robot 4 has a movement speed of 90m / min on the X-axis, 30m / min on the Y-axis, and 60m / min on the Z-axis. The repeatability of the positioning is ≤±0.05mm, ensuring accurate positioning of the blank. The secondary positioning stage 5 performs attitude calibration on the blank and fixes it with a pneumatic clamp to ensure the consistency of the subsequent processing reference.

[0021] Specifically, such as Figure 1 As shown, the robot arm transfers the positioned blank to the spindle of the CNC lathe, and the 12-inch imported hydraulic power chuck achieves internal support or external clamping. The chuck has a high and low pressure conversion function. High pressure clamping ensures machining stability, and low pressure release avoids damage to the workpiece surface.

[0022] Specifically, such as Figure 1As shown, the FANUC31i CNC system monitors tool life in real time, sets tool wear thresholds, automatically calculates machining time and triggers alarms. For example, when turning a φ280mm piston, the system calculates the cumulative tool usage time based on the preset cycle time of 870 seconds / piece. It automatically prompts for tool replacement before the tool reaches its life limit. The tool monitoring system detects chipping through vibration sensors. Once an abnormality is detected, machining is immediately paused to avoid the generation of scrap.

[0023] Specifically, such as Figure 1 As shown, the processed workpiece is transferred by a robotic arm to station 7 of the laser marking machine, where a tracking number and QR code are printed on the end face. The marking repeatability is ±0.005mm, and the minimum character size is 0.2mm. After marking, the workpiece is scanned by a Keyence barcode scanner. Qualified parts are sent to the finished product buffer position via unloading conveyor line 3. Unqualified parts, such as those with blurry markings or out-of-tolerance dimensions, are diverted to the NG conveyor via the NG barcode scanner channel 6 for manual re-inspection or scrapping. During the unloading process, the workpiece is automatically flushed to remove surface iron filings, ensuring that the finished product is free of impurities. Qualified finished products are temporarily stored in the finished product buffer position, awaiting centralized packaging. The buffer position capacity is designed according to the production cycle and can store 20-30 finished products to avoid production line blockage.

[0024] Specifically, such as Figure 1 As shown, the FANUC CNC system, which is the main control PLC controller, communicates with the machine tool, gantry robot, laser marking machine 7 and other equipment through the bus to coordinate the actions of each unit. For example, after the machine tool completes processing, it sends a "workpiece ready" signal. After receiving the signal, the robot performs the unloading action and triggers the laser marking machine 7 to prepare. The HMI display shows the production line status in real time, such as processing progress, equipment fault codes, process parameters such as spindle speed 3500r / min, feed speed 24m / min, and output statistics such as 120 piston 140 / 80 models completed in the shift.

[0025] Specifically, such as Figure 1 As shown, the machine tool seamlessly connects with the client's MES system via a high-speed Ethernet interface, automatically receives work orders, locks the current machining program to prevent accidental switching, and automatically reports completion data after machining, including part number, machining time, operator, etc., and synchronously updates the production progress dashboard in the MES system.

[0026] Specifically, such as Figure 1 As shown, the machine tool's front door is an automatic door with a human-machine interlock. When personnel approach, the door automatically stops opening and closing, and a signal indicating that the door is closed is fed back to the control system, ensuring that personnel cannot access dangerous areas during processing. The top safety door prevents foreign objects from falling into the machine tool. Infrared gratings are installed around the material hopper, and the feeding process is paused when personnel are detected entering. The turret anti-collision protection monitors the turret position in real time through sensors to avoid collisions between the upper and lower turrets, reducing the risk of equipment damage.

[0027] In summary, this automatic production machine tool for motor housings, through the setup of a three-axis gantry robot 4 and in conjunction with the feeding conveyor line 2, can feed raw materials into the machine tool body 9 for processing. The processed raw materials will enter a temporary storage table, and the finished products will be marked with a laser marking machine 7. At the same time, the workpieces will be scanned and confirmed by the NG barcode scanner 6. Workpieces that pass the barcode scan will be sent out through the unloading conveyor line 3, while those that fail will be sent out through the NG conveyor table. This achieves the goal of automating the production process, improving production efficiency and processing accuracy, and reducing production costs.
