Description

Technical Field

[0001] This invention relates to the field of sensor manufacturing technology, specifically to a composite processing device for automotive sensor housings. Background Technology

[0002] In the production of automotive sensor housings, milling and turning machining centers or Swiss-type CNC lathes are widely used. For example, the housings of oxygen sensors and temperature sensors have typical rotating body characteristics in terms of structure. Metal bars are commonly used as raw materials. The automatic feeding of long bars, turning of outer diameter, precision threading and end face forming and other rotating body processing processes are integrated into one, realizing efficient unmanned operation from bar stock to formed housing.

[0003] Currently, in existing technologies, the grinding of the sensor housing surface after turning requires centralized collection and manual handling to a separate belt polisher, magnetic grinder, or drum grinder for batch grinding. However, the manual transfer and batch accumulation between processes make the processed surface very susceptible to secondary bumps and scratches during handling, which weakens the precision gains of the previous precision machining and makes it difficult to guarantee the yield rate.

[0004] Therefore, it is necessary to design a composite machining device for automotive sensor housings that organically integrates turning and grinding. Summary of the Invention

[0005] The purpose of this invention is to provide a composite processing apparatus for automotive sensor housings to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a composite processing device for automotive sensor housings, comprising a turning machine, a grinding mechanism, a feeding mechanism, and a receiving mechanism. The feeding mechanism is located at one end of the turning machine. A conveyor, a second conveyor, and a scrap bin are provided on the side of the turning machine near the receiving mechanism. The scrap bin is located at the intersection of the first and second conveyors. The grinding mechanism is located above the first conveyor. The receiving mechanism is located at one end of the first conveyor and corresponds to the position of the chuck of the turning machine. When the turning machine cuts off the processed workpiece, the workpiece falls and contacts the receiving mechanism. When the workpiece requires secondary processing, the grinding mechanism contacts the outer circle of the workpiece to perform outer circle grinding. When the workpiece is defective, the workpiece is located in the scrap bin.

[0007] According to the above technical solution, the feeding mechanism includes a feeding seat, a sliding assembly, and a feeding chuck. The slide rail of the sliding assembly is fixedly connected above the feeding seat, and the feeding chuck is fixedly connected above the slider of the sliding assembly. A bar stock is inserted inside the feeding chuck, and a support frame is provided between the feeding chuck and the turning machine tool. The bar stock is inserted into the support frame and the hollow clamping chuck of the turning machine tool. The bar stock is connected to the support frame by a bearing. By driving the drive motor of the sliding assembly, the feeding chuck moves along the slide rail axis toward the turning machine tool, thereby realizing feeding.

[0008] According to the above technical solution, the bed of the turning machine tool is provided with a moving groove, and a baffle is slidably connected inside the moving groove. A cylinder is provided on the side of the turning machine tool facing the conveyor. The telescopic rod of the cylinder is fixedly connected to the baffle. A plastic plate is provided at the end of the conveyor near the receiving mechanism. A motor is fixedly connected to one side of the conveyor. The output shaft of the motor is fixedly connected to the plastic plate. This is used to buffer the impact force generated when the workpiece rolls and unloads, and to prevent multiple workpieces from colliding.

[0009] According to the above technical solution, the receiving mechanism includes an ejector, a rotating seat, and a rolling seat. A frame is provided on the side of the turning machine tool near the receiving mechanism. The frame is generally inverted U-shape. A cylinder is hinged inside the frame. The rolling seat is fixedly connected to the top of the frame and is generally U-shaped. Multiple sets of first rollers are connected to the bearings inside the rolling seat. The axis of the first roller is perpendicular to the axis of the conveyor. The straight line connecting the highest points of the multiple sets of first rollers is inclined and the inclined axis faces the conveyor. An inclined block is fixedly connected to one end of the rolling seat near the conveyor. The upper end of the inclined block corresponds to the first roller, and the lower end of the inclined block corresponds to the anti-slip belt of the conveyor. The rotating seat is hinged to the other end of the rolling seat. Cylinders are hinged to both sides of the rolling seat symmetrically along the forward axis of the conveyor. The axis of the cylinder is perpendicular to the axis of the first roller.

[0010] According to the above technical solution, the ejector frame is installed inside the rotating seat. The ejector frame has an anti-slip groove inside, which is arc-shaped and its axis is perpendicular to the forward axis of the conveyor. A connecting rod is hinged to the side of the rotating seat away from the ejector frame. The connecting rod is hinged to the piston rod of cylinder two. A through sliding groove is opened on both sides of the rotating seat along the forward direction of conveyor one. Slide rods are fixedly connected to both sides of the ejector frame. The slide rods pass through the sliding grooves and are fixedly connected to the piston rod of cylinder three. By driving cylinder three to operate, the piston rod moves the ejector frame along the sliding groove. By driving cylinder two, the piston rod moves the connecting rod, and then the connecting rod pushes the rotating seat to rotate around the hinge point with the rolling seat.

[0011] According to the above technical solution, a truss is provided above the conveyor, and a multi-axis moving assembly is fixedly connected above the truss. The multi-axis moving assembly includes a horizontal moving assembly, a vertical moving assembly, and a horizontal moving assembly, which can realize movement in multiple directions. A suction cup is provided below the vertical moving assembly of the multi-axis moving assembly. The suction cup is used to grip the workpiece. An industrial camera and multiple sets of vision sensors are fixedly connected below the truss. The industrial camera is located on the side of the truss closer to the receiving mechanism. The industrial camera is used to detect the outer diameter accuracy of the machined workpiece, and the vision sensors are used to monitor the status of the workpiece when it is transported on the conveyor.

[0012] According to the above technical solution, the second conveyor is connected to the first conveyor. The grinding mechanism is located on the side of the second conveyor away from the receiving mechanism. The grinding mechanism includes a grinding seat, a first bracket, and a second bracket. The first bracket is fixedly connected to the lower ends of both ends of the grinding seat, and the second bracket is fixedly connected to one side of the grinding seat. The two sets of first brackets are fixedly connected to both sides of the first conveyor. An arc-shaped groove is opened in the center of the upper part of the grinding seat and is adapted to the shape of the workpiece. Multiple sets of ball bearings are embedded in the arc-shaped groove, which can rotate synchronously with the workpiece and play a supporting and limiting role for the workpiece. A cylinder four is fixedly connected to the side of the second bracket away from the grinding seat. When the grinding mechanism is working, the piston rod of the cylinder four extends and abuts against the workpiece, thereby pushing the workpiece to move along the axis of the arc-shaped groove.

[0013] According to the above technical solution, two sets of motors are fixedly connected above the grinding base, and the output shaft of each set of motors is fixedly connected to an abrasive wheel for grinding and deburring the outer circle of the workpiece.

[0014] According to the above technical solution, an air compressor is provided on one side of the frame, and an air blowing pipe is connected to the air outlet pipe of the air compressor. The air outlet of the air blowing pipe corresponds to the position of the bar stock and is used to blow air onto the workpiece when cutting and unloading the workpiece in the last step, so as to prevent the debris from falling onto the receiving mechanism. A negative pressure dust collection device is provided on the other side of the frame for cleaning debris.

[0015] According to the above technical solution, the method of using the automated processing equipment for automotive sensor production includes: Step 1: Clamping and feeding of bar stock; Step 2: Turning and machining; Step 3: Preparation for cutting; Step 4: Cut and unload; Step 5: Detect and determine the flow.

[0016] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: By setting the turning inspection process and the grinding process to be completed simultaneously, this invention eliminates the need for manual secondary handling and manual quality inspection and sorting, reducing labor costs. It also facilitates tool maintenance based on workpiece defect data. By setting up an ejector with anti-slip arc grooves and a buffer plastic plate, the workpiece can be smoothly received and buffered to slow down when it is cut and falls, avoiding high-speed rolling and collisions between workpieces. At the same time, the material receiving structure can avoid collisions and block chips by linking with the cylinder. By setting up an automatic bar feeding, turning and forming, online material receiving and conveying, visual inspection, external cylindrical grinding, and defective product sorting into a fully automated production line, this invention breaks the traditional processing mode of separating turning and grinding processes and manually transferring workpieces, effectively avoiding secondary scratches and bumps on the workpiece surface, and significantly improving production efficiency.

A support frame 12 is provided between the feeding chuck 10 and the turning machine tool 1. The bar stock 11 is inserted into the support frame 12 and the hollow clamping chuck of the turning machine tool 1. The bar stock 11 is connected to the support frame 12 by a bearing. By driving the drive motor of the sliding assembly 9, the feeding chuck 10 moves the bar stock 11 along the slide rail axis toward the turning machine tool 1, thereby realizing feeding.

[0021] The lathe bed of the turning machine tool 1 has a moving groove 13, and a baffle 14 is slidably connected inside the moving groove 13. A cylinder 15 is provided on the side of the turning machine tool 1 facing the conveyor 5. The telescopic rod of the cylinder 15 is fixedly connected to the baffle 14.

[0022] The receiving mechanism 4 includes an ejector frame 16, a rotating seat 17, and a rolling seat 18. A frame 19 is provided on one side of the turning machine tool 1 near the receiving mechanism 4. The frame 19 is in an inverted U-shape. A cylinder 22 is hinged inside the frame 19. The rolling seat 18 is fixedly connected above the frame 19 and is in a U-shape. Multiple sets of first rollers 20 are connected to the bearings inside the rolling seat 18. The axis of the first rollers 20 is perpendicular to the axis of the conveyor 5. The straight line connecting the highest points of the multiple sets of first rollers 20 is inclined and the inclined axis faces the conveyor 5. An inclined block 21 is fixedly connected to one end of the rolling seat 18 near the conveyor 5. The upper end of the inclined block 21 corresponds to the first roller 20, and the lower end of the inclined block 21 corresponds to the anti-slip belt of the conveyor 5. The rotating seat 17 is hinged to the other end of the rolling seat 18. Cylinders 25 are hinged to both sides of the rolling seat 18 symmetrically along the forward axis of the conveyor 5. The axis of the cylinders 25 is perpendicular to the axis of the first roller 20.

[0023] The ejector frame 16 is located inside the rotating seat 17. The ejector frame 16 has an anti-slip groove 26 inside. The anti-slip groove 26 is arc-shaped and its axis is perpendicular to the forward axis of the conveyor 5. A connecting rod 27 is hinged to the side of the rotating seat 17 away from the ejector frame 16. The connecting rod 27 is hinged to the piston rod of the cylinder 22. The rotating seat 17 has through sliding grooves 23 on both sides along the forward direction of the conveyor 5. Slide rods 24 are fixedly connected to both sides of the ejector frame 16. The slide rods 24 pass through the sliding grooves 23 and are fixedly connected to the piston rod of the cylinder 35. By driving the cylinder 325 to operate, the piston rod moves the ejector frame 16 along the sliding grooves 23. By driving the cylinder 22, the piston rod moves the connecting rod 27. In turn, the connecting rod 27 pushes the rotating seat 17 to rotate around the hinge point with the rolling seat 18.

[0024] A truss 28 is installed above the conveyor 5. A multi-axis moving assembly 29 is fixedly connected above the truss 28. The multi-axis moving assembly 29 includes a horizontal moving assembly, a vertical moving assembly, and a horizontal moving assembly. All of them are composed of a drive motor, pulleys, drag chains, slide rails, sliders, etc., which are existing technologies and will not be described in detail. They can move in multiple directions. A suction cup is installed below the vertical moving assembly of the multi-axis moving assembly 29. The suction cup is a magnetic suction cup, which is existing technology. The suction cup is used to grip the workpiece. An industrial camera 30 and multiple sets of vision sensors (not shown in the figure) are fixedly connected below the truss 28. The industrial camera 30 is located on the side of the truss 28 near the receiving mechanism 4. The industrial camera 30 is used to detect the outer diameter accuracy of the turned workpiece. The vision sensors are used to monitor the status of the workpiece during transportation on the conveyor 5.

[0025] Conveyor 2 6 is connected to conveyor 1 5. Grinding mechanism 2 is located on the side of conveyor 2 6 away from receiving mechanism 4. Grinding mechanism 2 includes grinding seat 31, bracket 1 32 and bracket 2 33. Bracket 1 32 is fixedly connected to the lower ends of grinding seat 31, and bracket 2 33 is fixedly connected to one side of grinding seat 31. The two sets of bracket 1 32 are fixedly connected to the two sides of conveyor 1 5. An arc groove 36 is opened in the center of the upper part of grinding seat 31 and is adapted to the shape of the workpiece. Multiple sets of ball bearings 34 are embedded in the arc groove 36. The ball bearings 34 can rotate freely. This is the prior art. They can rotate synchronously with the workpiece and play a supporting and limiting role for the workpiece. A cylinder 4 38 is fixedly connected to the side of bracket 2 33 away from grinding seat 31. When grinding mechanism 2 is working, the piston rod of cylinder 4 38 extends and abuts against the workpiece, thereby pushing the workpiece to move along the axis of arc groove 36.

[0026] Two sets of motors 35 are fixedly connected above the grinding base 31. The output shaft of each set of motors 35 is fixedly connected to an abrasive wheel 37. The abrasive wheel 37 is made of stacked sheet sandpaper, which is existing technology, and is used to grind and deburr the outer circle of the workpiece.

[0027] An air compressor 41 is provided on one side of the frame 19. The air outlet pipe of the air compressor 41 is connected to an air blowing pipe 42. The air outlet of the air blowing pipe 42 corresponds to the position of the bar stock 11. It is used to blow air onto the workpiece during the final step of cutting and unloading the workpiece, thereby preventing debris from falling onto the receiving mechanism 4. A negative pressure dust collection device (not shown in the figure) is provided on the other side of the frame 19 for cleaning debris.

[0028] Example 1: A method of using an automotive sensor housing composite processing apparatus, comprising the following steps: Step 1: Clamping and feeding of bar stock 11.

[0029] Specifically, the long bar stock 11 is inserted through the hollow rotary support assembly of the feeding chuck 10, and then sequentially passes through the support frame 12 and the hollow clamping chuck of the turning machine tool 1, so that the front end of the bar stock 11 extends beyond the preset length of the clamping chuck of the turning machine tool 1. The pneumatic clamping drive unit of the feeding chuck 10 drives the jaws to clamp the bar stock 11. The drive motor of the sliding assembly 9 is started, and the slider drives the feeding chuck 10 to move along the slide rail axis toward the turning machine tool 1. The bar stock 11 is smoothly fed into the clamping chuck of the turning machine tool 1 under the support of the bearings of the support frame 12. The clamping chuck of the turning machine tool 1 clamps the bar stock 11, and the feeding chuck 10 releases and retracts to the end of the bar stock 11 away from the turning machine tool 1, completing one feeding cycle.

[0030] Step 2: Turning and machining.

[0031] Specifically, the chuck of the turning machine tool 1 drives the bar stock 11 to rotate at high speed. The turret rotates and switches tools according to a preset program, sequentially calling external turning tools, internal drilling tools, threading tools, and drills or milling cutters driven by a power tool holder, etc., to perform external turning, end face machining, drilling, thread turning, and other feature machining on the protruding part of the bar stock 11. During the machining process, the telescopic rod of cylinder 15 extends, and the baffle 14 blocks the opening of the turning machine tool 1 facing the conveyor 5 to prevent chips from splashing into the receiving mechanism 4 area. The piston rod of cylinder 22 extends, carrying the rotating seat 17 and the ejector 16 to rotate around the hinge point between the rotating seat 17 and the rolling seat 18 (e.g., Figure 11 As shown), this allows space for the baffle 14 to move.

[0032] Step 3: Cutting preparation.

[0033] Specifically, the extension rod of cylinder 15 extends, causing the baffle 14 to move along the moving groove 13, opening the turning machine tool 1 towards the conveyor 5. The piston rod of cylinder 22 retracts, pushing the rotating seat 17 downwards around the hinge point with the rolling seat 18 via the connecting rod 27, causing the rotating seat 17 and its internal ejector 16 to be in a slightly tilted state (e.g., Figure 6As shown), the piston rod of cylinder 25 extends and pushes the slide rod 24 to move along the sliding groove 23, so that the ejector 16 is located below the hollow chuck of the turning machine tool 1, which facilitates material receiving.

[0034] Step 4: Cut and unload.

[0035] Specifically, the cutting blade on the turret cuts the workpiece. Simultaneously, the air compressor 41 blows a small amount of compressed air to the cutting position through the air pipe 42, blowing the chips generated during cutting away from the receiving mechanism 4 area. After the workpiece is cut, it falls. The air compressor 41 is then turned off, and the workpiece falls into the ejector frame 16. The anti-slip groove 26, with its slightly arc-shaped structure, supports the falling workpiece, preventing it from bouncing or colliding with each other, and also buffering the rolling speed of the workpiece without affecting normal workpiece transport. The workpiece follows the inclined ejector frame 16, passing sequentially on the rotating seat 17 and the rolling seat 18. The inclined surfaces of roller 20 and inclined block 21 continue until the workpiece falls onto conveyor 5. When the workpiece falls onto conveyor 5, the piston rod of cylinder 3 25 retracts, retracting the ejector 16 into the rotating seat 17. The piston rod of cylinder 22 extends, causing the rolling seat 18 to rotate upward. The piston rod of cylinder 15 extends, and the baffle 14 blocks the opening again. The sliding assembly 9 is activated, and the clamping chuck of the turning machine tool 1 releases the bar stock 11, causing the feeding chuck 10 to clamp the bar stock 11 for feeding. The clamping chuck clamps the bar stock 11 again, thus starting the turning process of the next workpiece.

[0036] Step 5: Detect and determine the flow.

[0037] Specifically, when the workpiece falls onto the anti-slip belt of conveyor 5, it will continue to roll due to inertia. The industrial camera 30 takes multiple consecutive pictures of the outer circle of the workpiece to obtain the dimensional accuracy of the outer circle. When the workpiece rolls and hits the plastic plate 39, the micro-elasticity of the plastic plate 39 absorbs the impact force of the workpiece falling, and the workpiece stops rolling and remains stable. The motor 3 40 is started, causing the plastic plate 39 to rotate around the output shaft of the motor 3 40, thereby clearing the conveying channel. After the workpiece passes the plastic plate 39, the motor 3 40 is started again to return the plastic plate 39 to its original position, waiting to provide a stable limit for the next workpiece.

[0038] Furthermore, after the industrial camera 30 acquires the outer diameter accuracy of the workpiece, it performs a sorting and judgment. If the outer diameter of the workpiece is qualified and needs to be polished, it enters the polishing mode. If the workpiece is qualified and does not need to be polished, it enters the conveyor 6. If the workpiece is unqualified, it enters the scrap bin 7.

[0039] Example 2: Based on the device structure of Example 1, this example provides a detailed analysis of step five, where turning is performed under stable clamping conditions.

[0040] When the result obtained by the industrial camera 30 shows that the outer cylindrical surface is free of defects, the suction cup of the multi-axis moving assembly 29 is driven to grab the workpiece and slowly place the workpiece onto the conveyor 6.

[0041] When the industrial camera 30 detects irregular shallow scratches on the surface, it further determines the location of the scratches. If the scratches are located in non-grinding areas such as threaded surfaces, sealing cone surfaces, or chip mounting slots, or if the current workpiece size is close to the lower tolerance limit, the dimensions will be out of tolerance after grinding, and it is judged as an unrepairable product. It is then transferred to the scrap bin 7 by the multi-axis moving assembly 29. If the scratches are on the outer diameter, the workpiece is marked by a vision sensor and judged as a repairable product. It then enters the grinding station, and the suction cup of the multi-axis moving assembly 29 is driven to grab the workpiece. The multi-axis moving assembly 29 places the workpiece inside the grinding seat 31. At this time, the workpiece is located between the abrasive wheel 37 and the cylinder 4 38 (e.g., Figure 9 As shown), start motor 35, which drives abrasive wheel 37 to rotate around the output shaft of motor 35. Then start cylinder 38 to push the workpiece along the axis of arc groove 36. Abrasive wheel 37 contacts the outer circle of workpiece to grind and remove burrs until cylinder 38 pushes the workpiece out between the two sets of abrasive wheels 37. Grinding is completed. Motor 35 stops operating and drives multi-axis moving component 29 to grab the workpiece with suction cup. Then the workpiece is placed on conveyor 5 for continued conveying. The ground workpiece is located on the side of grinding mechanism 2 away from receiving mechanism 4.

[0042] Furthermore, when such defects are detected, staff are reminded to promptly check whether there are machining chips adhering to the anti-slip groove 26 of the ejector frame 16 and the surface of the first roller 20, which could cause secondary scratches when the workpiece rolls. If chips are found, the chips are removed and cleaned using a negative pressure dust collection device.

[0043] When the industrial camera 30 detects regular turning marks on the outer circle that are shallow or have tiny curled burrs, according to the above logic, since the depth of the shallow defect is much less than the amount to be removed by grinding and the defect location is in the grindable area, it is determined to be a repairable product and enters the grinding station. The above grinding operation is repeated. At the same time, if regular shallow turning marks are found N times in a row, the staff is reminded to check the tool wear. If the tool is found to be excessively worn or dull, the tool should be replaced in time to prevent deeper defects that cannot be corrected.

[0044] When the industrial camera 30 detects multiple deep scratches or obvious spiral steps on the outer diameter, it indicates that the defect depth exceeds the grinding capacity. Excessive grinding will cause dimensional deviations, and the workpiece is judged as defective. The workpiece is marked using a vision sensor, and the multi-axis moving assembly 29 is driven to move the workpiece above the scrap bin 7. Then, the suction is canceled, allowing the defective workpiece to fall into the scrap bin 7. Further, the surface of the bar stock 11 is checked for hard inclusions that could cause instantaneous tool damage or tool deflection. If present, the section of bar stock 11 with inclusions is cut off using the cutting blade on the turret. When the scrap is conveyed to the range of the multi-axis moving assembly 29 on the conveyor 5, the scrap is grabbed by a suction cup and placed into the scrap bin 7 before the next round of turning continues.
