Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner parts processing equipment, specifically a milling device for air conditioner radiators. Background Technology

[0002] The milling device for air conditioner radiators is used to process the fins of air conditioner radiators. Radiator fins are usually made of thin metal plates, such as aluminum or copper plates. These metal plates have good thermal conductivity and are suitable for radiator manufacturing. The milling device mills the shape of the fins into the metal plate, usually by cutting grooves in the metal plate to form the fin structure. (See prior art: Authorization Publication No. CN 216463119) U's patent discloses a milling device for easily fixing workpieces, including a milling structure and a fixing fixture. The milling structure is housed inside a housing, which is mounted on a support base. Multiple fixing fixtures are arranged above the support base. Each fixing fixture is connected to a horizontally arranged first connecting plate via a rotating shaft. A pull rod is connected through each first connecting plate. Although this device can move the fixtures via a lead screw to limit and fix the workpiece, the chips generated during milling enter the interior of the support base through a groove and eventually adhere to the outside of the lead screw. The chips adhering to the lead screw surface increase the friction between the lead screw and the nut, resulting in uneven feed movement and inaccurate fixture positioning. Inaccurate fixture positioning leads to a decrease in the quality of the workpiece and an increase in the defect rate. Therefore, we propose a milling device for air conditioner radiators.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-5 This embodiment provides a technical solution: a milling device for an air conditioner radiator, including a worktable 1, a placement groove 3 in the middle of the upper end of the worktable 1, a drive motor 11 at the upper end of the worktable 1, a milling head 12 at the lower end of the output shaft of the drive motor 11, and a fixing mechanism 4. Fixing mechanism 4 includes a limiting plate 45, an adjusting rod 46, a gear 47, and a rack plate 48. The adjusting rod 46 is rotatably connected to the middle of the bottom wall of the worktable 1. A gear 47 is provided on the upper side of the outer arc surface of the adjusting rod 46. A rack plate 48 is provided on the front and rear sides of the inside of the worktable 1, and both rack plates 48 are meshed with the gear 47. A limiting plate 45 is provided on the upper side of the placement groove 3. Fixing mechanism 4 also includes a crossbar 41, a connecting plate 42, a mounting plate 43, and a connecting arm 44. The crossbar 41 is provided on the upper side of the inside of the worktable 1. The two crossbars 41 are slidably connected to the sliding holes provided on the left end of the connecting plate 42. A rack plate 48 is provided on the inner side of the two connecting plates 42. Mounting plates 43 are slidably connected in the guide grooves opened on the upper side of the left and right walls of the worktable 1. The inner side of the two mounting plates 43 is respectively connected to the adjacent connecting plates 42 away from the inside of the worktable 1. One end of the mounting plate 43 is fixedly connected to the center. The upper end of the mounting plate 43 is provided with a connecting arm 44. Both connecting arms 44 are located outside the worktable 1. The inner ends of the two connecting arms 44 are provided with limit plates 45. During the rotation of the gear 47, the gear 47 will drive the rack plate 48 to move through meshing. The two rack plates 48 move in opposite directions. The rack plate 48 will drive the mounting plate 43 to move through the connecting plate 42. The mounting plate 43 will drive the limit plates 45 to move through the connecting arms 44. At this time, the distance between the two limit plates 45 will gradually decrease. Finally, the limit plates 45 will limit and fix the metal plate, replacing the traditional method of driving through the lead screw. This solves the problem of the movement accuracy being affected by the chips adhering to the outside of the lead screw during the milling process. It improves the stability of the metal plate, ensures the accuracy of the processing dimensions and the consistency of the product, and reduces the defect rate.

[0017] It also includes a microcontroller 2, which is located outside the workbench 1. The input terminal of the microcontroller 2 is electrically connected to an external power supply, and the input terminal of the drive motor 11 is electrically connected to the output terminal of the microcontroller 2, which can regulate the electrical components inside the equipment.

[0018] Specifically: A laser rangefinder 419 is installed on the front side of the left wall of the workbench 1. The laser rangefinder 419 corresponds to the left and right positions of the connecting plate 42 on the left. The laser rangefinder 419 is bidirectionally electrically connected to the microcontroller 2. During use, the built-in light source of the laser rangefinder 419 emits a laser beam to the left end of the connecting plate 42 on the left. When the laser comes into contact with the left end of the connecting plate 42 on the left, it is reflected. Then the laser rangefinder 419 receives the reflected light. The laser rangefinder 419 calculates the distance between the laser rangefinder 419 and the left end of the connecting plate 42 on the left by measuring the round-trip time (TOF) or phase difference of the laser.

[0019] The workbench 1 has a servo motor 5 on the lower side of its front wall, a worm gear 6 on the rear end of its output shaft, and a worm wheel 7 on the lower side of the outer arc surface of the adjusting rod 46. The worm gear 6 and the worm wheel 7 are meshed together. The input end of the servo motor 5 is electrically connected to the output end of the microcontroller 2. When the servo motor 5 starts running, its output shaft drives the worm gear 6 to rotate. During the rotation, the worm gear 6 drives the worm wheel 7 to rotate through the meshing connection. During the rotation, the worm wheel 7 drives the gear 47 to rotate through the adjusting rod 46.

[0020] The workbench 1 has the following components: a mounting bracket 8 is slidably connected to a slide groove on the rear side of the upper end; a fixing bracket 9 is slidably connected to the upper side of the mounting bracket 8; a connecting seat 10 is slidably connected to the inside of the fixing bracket 9; a drive motor 11 is located in the middle of the lower end of the connecting seat 10; an electric push rod 13 is located in the middle of the right wall of the slide groove; the left end of the telescopic end of the electric push rod 13 is fixedly connected to the right end of the mounting bracket 8; a laser rangefinder 14 is located in the middle of the left wall of the slide groove; the laser rangefinder 14 corresponds to the left and right positions of the mounting bracket 8; and the electric push rod 1... The input terminal of 13 is electrically connected to the output terminal of the microcontroller 2. The laser rangefinder 14 is bidirectionally electrically connected to the microcontroller 2. Through the control of the microcontroller 2, the electric push rod 13 starts to run. The telescopic end of the electric push rod 13 is shortened, so that the electric push rod 13 drives the milling head 12 to move to the left through the mounting bracket 8. During the movement, the milling head 12 grooves the metal plate along the marks. When the distance between the right end of the laser rangefinder 14 and the left end of the mounting bracket 8 is equal to p, it means that the milling and grooving of the metal plate has been completed.

[0021] The following features a motor: an electric push rod 15 is installed in the middle of the rear wall of the fixed frame 9. The front end of the telescopic end of the electric push rod 15 is fixedly connected to the rear end of the connecting seat 10. A laser rangefinder 16 is installed in the middle of the front wall of the fixed frame 9. The laser rangefinder 16 corresponds to the front and rear positions of the connecting seat 10. The input end of the electric push rod 15 is electrically connected to the output end of the microcontroller 2. The laser rangefinder 16 is bidirectionally electrically connected to the microcontroller 2. Through the control of the microcontroller 2, the electric push rod 15 starts to run. The telescopic end of the electric push rod 15 extends, thereby causing the connecting seat 10 to drive the milling head 12 to move backward through the drive motor 11. When the distance between the rear end of the laser rangefinder 16 and the front end of the connecting seat 10 is equal to m, it means that the milling head 12 has moved to the upper side of the mark (the radial force of the electric push rod 15 is slidably borne by the fixed frame 9, and the electric push rod 15 is only subjected to the front and rear axial force).

[0022] Among them: an electric push rod 17 is set in the middle of the bottom wall of the mounting frame 8. The upper end of the telescopic end of the electric push rod 17 is fixedly connected to the lower end of the fixed frame 9. A laser rangefinder 18 is set on the front side of the lower end of the connecting seat 10. The input end of the electric push rod 17 is electrically connected to the output end of the microcontroller 2. The laser rangefinder 18 is bidirectionally electrically connected to the microcontroller 2. Through the control of the microcontroller 2, the drive motor 11 and the electric push rod 17 start to run. The output shaft of the drive motor 11 drives the milling head 12 to rotate. At the same time, the telescopic end of the electric push rod 17 extends, so that the electric push rod 17 drives the milling head 12 to move downward through the drive motor 11. When the distance between the lower end of the laser rangefinder 18 and the upper end of the metal plate is equal to n, it means that the milling head 12 has been inserted into the interior of the metal plate.

[0023] The working principle of the milling device for air conditioner radiators provided by this utility model is as follows: Before use, the metal plate for making the air conditioner radiator is placed on the upper end of the workbench 1. Then, the operator measures the width of the metal plate and the distance between the two limiting plates 45 (e.g., a and b). Then, the distance between the right end of the laser rangefinder 419 and the left end of the left connecting plate 42 is measured. During the use of the laser rangefinder 419, the built-in light source of the laser rangefinder 419 emits a laser beam to the left end of the left connecting plate 42. When the laser comes into contact with the left end of the left connecting plate 42, it is reflected. Then, the laser rangefinder 419 receives the reflected light. The laser rangefinder 419 measures the round-trip time (TOF) or phase difference of the laser. This allows for the calculation of the distance between the laser rangefinder 419 and the left end of the connecting plate 42 (e.g., denoted as c). The laser rangefinder 419 then transmits the detected information to the microcontroller 2 via its built-in data transmission module. The microcontroller 2 receives the detected data via its built-in serial communication port. The distance between the laser rangefinder 419 and the left end of the connecting plate 42 is then added to the distance between the two limiting plates 45, minus the width of the metal plate, and divided by 2. This gives the distance between the laser rangefinder 419 and the left end of the connecting plate 42 when the limiting plate 45 contacts the outer surface of the metal plate (e.g., d, d = c + (ba) ÷ 2). Finally, through the control of the microcontroller 2, the servo motor 5 starts running, and the servo motor 5... The output shaft drives the worm gear 6 to rotate. During rotation, the worm gear 6 drives the worm wheel 7 to rotate through meshing. The worm wheel 7 drives the gear 47 to rotate through the adjusting rod 46. The gear 47 drives the rack plate 48 to move through meshing. The two rack plates 48 move in opposite directions. The rack plate 48 drives the mounting plate 43 to move through the connecting plate 42. The mounting plate 43 drives the limiting plate 45 to move through the connecting arm 44. At this time, the distance between the two limiting plates 45 gradually decreases. When the distance between the laser rangefinder 419 and the left end of the left connecting plate 42 is equal to d, it means that the limiting plate 45 is in contact with the outer surface of the metal plate, thereby achieving the limiting and fixing of the metal plate. During the milling process of the metal plate, a groove needs to be cut at the upper end of the metal plate to form the structure of the heat sink fins. Therefore, when the operator marks the milling marks on the upper surface of the metal plate with a marker, the marks are usually a straight line. After marking, the operator measures the distance between the lower end of the milling head 12 and the upper end of the metal plate, the distance between the milling head 12 and the rightmost end of the mark, the distance between the milling head 12 and the center of the upper end of the mark, and the required milling depth (e.g., e, f, g, and h). Then, the operator measures the distance between the right end of the laser rangefinder 14 and the left end of the mounting bracket 8, the distance between the rear end of the laser rangefinder 16 and the front end of the connecting seat 10, and the distance between the lower end of the laser rangefinder 18 and the upper end of the metal plate (e.g., i, j, and k).The measurement principles of laser rangefinder 1 (14), laser rangefinder 2 (16), and laser rangefinder 3 (18) are the same as those of laser rangefinder 4 (19). The distance between the right end of laser rangefinder 14 and the left end of mounting bracket 8, plus the distance between milling head 12 and the rightmost end of the mark, gives the distance between the right end of laser rangefinder 14 and the left end of mounting bracket 8 when milling head 12 moves to the rightmost end of the mark (let's call it l, l = f + i). The distance between the rear end of laser rangefinder 2 (16) and the front end of connecting seat 10, plus the distance between milling head 12 and the center of the upper end of the mark, gives the distance between the rear end of laser rangefinder 2 (16) and the front end of connecting seat 10 when milling head 12 moves to the upper side of the mark. (If denoted as m, m = j + g), the distance between the lower end of the laser rangefinder 18 and the upper end of the metal plate, plus the distance between the lower end of the milling head 12 and the upper end of the metal plate, and the required milling depth, can be used to determine the distance between the lower end of the laser rangefinder 18 and the upper end of the metal plate when the milling head 12 is inserted into the metal plate (if denoted as n, n = k + e + h). Then, through the control of the microcontroller 2, the electric push rod 13 starts to run. The telescopic end of the electric push rod 13 extends first, thereby causing the electric push rod 13 to drive the milling head 12 to move to the right through the mounting bracket 8. When the distance between the right end of the laser rangefinder 14 and the left end of the mounting bracket 8 is equal to l, this indicates that the milling head 12 is on the right side of the upper end of the mark. The radial force of electric push rod 13 is slidably supported by the bottom wall of the groove, and electric push rod 13 is only subjected to left and right axial forces. Then, through the control of the microcontroller 2, electric push rod 15 starts to run. The telescopic end of electric push rod 15 extends, so that the connecting seat 10 drives the milling head 12 to move backward through the drive motor 11. When the distance between the rear end of laser rangefinder 16 and the front end of connecting seat 10 is equal to m, it means that the milling head 12 has moved to the upper side of the mark (the radial force of electric push rod 15 is slidably supported by the fixing frame 9, and electric push rod 15 is only subjected to front and rear axial forces). Set the length of the marked mark to o, and add o to l, we can get the length of the right end of laser rangefinder 14 after the metal plate is grooved. The distance between the laser rangefinder 18 and the left end of the mounting bracket 8 (let's say p, p = l + o) is then controlled by the microcontroller 2. The drive motor 11 and the electric push rod 17 then begin operation. The output shaft of the drive motor 11 rotates the milling head 12. Simultaneously, the telescopic end of the electric push rod 17 extends, causing it to move the milling head 12 downwards via the connecting seat 10. When the distance between the lower end of the laser rangefinder 18 and the upper end of the metal plate equals n, it indicates that the milling head 12 has entered the interior of the metal plate. Then, controlled by the microcontroller 2, the electric push rod 13 begins operation, and its telescopic end shortens, causing it to move the milling head 12 to the left via the mounting bracket 8.During its movement, the milling head 12 grooves the metal plate along the markings (during the grooving process, external cooling equipment continuously sprays coolant to cool the grooved area). When the distance between the right end of the laser rangefinder 14 and the left end of the mounting bracket 8 equals p, the milling and grooving of the metal plate is complete. During the movement of the milling head 12, the radial force of the electric push rod 17 is borne by the sliding support of the mounting bracket 8, and the electric push rod 17 is only subjected to vertical axial forces.
