Technical Field
[0001] This invention relates to the field of automotive parts processing equipment technology, specifically a semi-automatic assembly and testing machine for vacuum electronic pump parts. Background Technology
[0002] With the increasing adoption of electric vehicles, automakers have placed higher demands on their safety. Electric vehicle braking systems require the use of electronic vacuum pumps.
[0003] The assembly of electric vacuum pumps requires the use of appropriate assembly equipment. During assembly, the stator needs to be placed on the suction plate, fitting the stator onto the rotor located in the center of the suction plate. However, traditional assembly equipment lacks precision, and the stator's installation position is prone to misalignment. This results in unequal distances from the rotor to different parts of the stator's inner wall, causing misalignment between the screw holes on the stator and those on other parts. Consequently, screws cannot penetrate the corresponding screw holes, preventing the parts from being assembled together. Therefore, a detection mechanism capable of measuring the distance between the stator and rotor during the assembly process is proposed. Summary of the Invention

[0009] A through slot is provided in the center of the stator. The cross-section of the through slot is elliptical. Four laser detectors emit lasers downwards, and the laser landing points correspond to the four vertices of the elliptical through slot. When the stator is correctly positioned, the laser beam just contacts the inner wall of the stator. If the stator is not correctly positioned, the stator position will be deviated, and some laser beams will touch the stator. At this time, the laser detectors will feed the information back to the computer terminal.
[0010] It also includes two sets of fixing components, which are located on the left and right sides of the base respectively. The fixing components are equipped with screws, which are used to thread the electronic pump body, stator and exhaust plate together.
[0011] Preferably, the bottom of the placement box has four grooves arranged in a ring at equal angles. A sliding rod is connected to the outside of the placement box, and the sliding rod corresponds to each groove. The lower end of the sliding rod has a horizontal section that extends into the groove.

[0014] Preferably, the fixing assembly includes two connecting plates, two arc-shaped housings, an electric actuator, a small motor, and two electromagnet modules. The two arc-shaped housings are located between the two connecting plates and are close together. The upper ends of the arc-shaped housings are hinged to the connecting plates. The electromagnet modules are located inside the arc-shaped housings. The two arc-shaped housings cover the electric actuator.

[0015] Preferably, the small motor drive shaft is vertically connected to a hexagonal column, the hexagonal column is connected to the top of the screw, and the electric push rod two is arranged vertically.
[0016] Preferably, the arc-shaped housing is beak-shaped. When the electromagnet module is energized, it generates a magnetic field that attracts the two arc-shaped housings, causing the lower end of the arc-shaped housing to clamp the screw rod.
[0017] Preferably, a slide rail is provided above the base, and both the mounting box and the cylinder are provided with drive components. The drive components are slidably engaged with the slide rail. A slide rail is provided on the outside of the slide rail. A movable seat is slidably engaged with the slide rail.

[0019] This invention provides a semi-automatic assembly and testing machine for vacuum electronic pump parts. It has the following advantages:
[0020] This semi-automatic assembly and testing machine for vacuum electronic pump parts consists of a placement box, a cylinder, and a fixing component. The placement box is used to transport the stator and place it over the rotor, replacing the traditional manual placement method and speeding up the assembly of the electronic pump. A laser detector is installed at the bottom of the cylinder to detect the apex of the inner wall of the stator through laser. Based on whether the apex of the inner wall of the stator touches the laser, it is determined whether there is a deviation in the placement position of the stator.
[0021] This semi-automatic assembly and testing machine for vacuum electronic pump parts consists of a fixing component made up of two arc-shaped housings, an electric push rod, a small motor, and an electromagnet module. The electromagnet module generates a magnetic field when energized, which causes the lower ends of the two arc-shaped housings to move closer together, thus clamping the screws at the lower ends of the housings and preventing the screws from falling off during the movement of the fixing component.
[0022] This semi-automatic assembly and testing machine for vacuum electronic pump parts has four electric push rods slidingly fitted at the bottom of the mounting box. The lower end of each electric push rod is connected to a shovel, which serves to support the stator. The electric push rod extends and contacts the top of the electronic pump body, so that the stator is fitted over the rotor. This replaces manual placement and improves accuracy. The exhaust plate cover is pressed down on the stator with a crossbar to prevent the parts from sliding during the screw fixing process, thus achieving the purpose of assembling the parts together.

[0032] This invention provides a semi-automatic assembly and testing machine for vacuum electronic pump parts, such as... Figure 1-8 As shown, the exhaust plate 8 and stator 7 are mounted on the electric pump body 6. The top of the electric pump body 6 exposes the rotor 9, the stator 7 is fitted over the rotor 9, and the exhaust plate 8 covers the stator 7. The system includes a base 1 with a central hole at the top center. The lower end of the electric pump body 6 is inserted into the central hole of the base 1. The mounting box 2 and cylinder 3 are slidably fitted on the top of the base 1.
[0033] The placement box 2 has a through conveying channel 21 in the center, which is arranged vertically. The bottom of the placement box 2 is connected to a clamping assembly for clamping the stator 7. The cylinder 3 is located in front of the placement box 2, and four laser detectors 31 are fixedly installed at the bottom of the cylinder 3.
[0034] A through slot is provided in the center of the stator 7. The cross-section of the through slot is elliptical. Four laser detectors 31 emit lasers downwards, and the laser landing points correspond to the four vertices of the elliptical through slot.
[0035] During the testing process, cylinder 3 extends, bringing laser detector 31 closer to stator 7. When stator 7 is correctly positioned, the laser beam contacts the inner wall of stator 7. If stator 7 is not correctly positioned, causing a deviation in its position, some laser beams may touch stator 7. In this case, laser detector 31 will send the information to the computer terminal, informing the operator that stator 7 is installed incorrectly.
[0036] It also includes two sets of fixing components 5, which are located on the left and right sides of the base 1 respectively. The fixing components 5 are equipped with screws 10, which thread the electronic pump body 6, stator 7 and exhaust plate 8 together.
[0037] The bottom of the placement box 2 has four grooves 23 arranged in a ring at equal angles. A sliding rod 24 is welded to the outside of the placement box 2. The sliding rod 24 corresponds to the groove 23 one by one. The lower end of the sliding rod 24 is a horizontal section that extends into the groove 23. The rod body of the groove 23 is slidably fitted with an electric push rod 26. The movable end of the electric push rod 26 is vertically downward and is fixedly installed with a shovel 261.
[0038] A spring 25 is fitted on the horizontal section of the slide bar 24. One end of the spring 25 is welded to the electric push rod 26. A rack 27 is fixedly installed on the top of the electric push rod 26. The rack 27 passes through the slide bar 24. A motor-driven pinion 28 is fixedly installed on the top of the inner wall of the groove 23. The pinion 28 meshes with the rack 27.
[0039] The aforementioned spring 25 is always under compression, and its elasticity causes the four electric actuators 26 to move closer together. By rotating the pinion 28, the pinion 28 pushes the rack 27 to move, thereby controlling the four electric actuators 26 to move away from each other.
[0040] During operation, the mounting box 2 moves forward to directly above the electronic pump body 6. The stator 7 slides into the mounting box 2 from the conveying channel 21 and eventually slides onto the lower end of the electric push rod 26, where the lower end of the electric push rod 26 extends and contacts the top of the electronic pump body 6. At this point, the stator 7 is fitted over the rotor 9. Then, the pinion 28 rotates, causing the four electric push rods 26 to move away from each other, and the stator 7 is placed on the electronic pump body 6. Immediately afterwards, the electric push rods 26 retract, the mounting box 2 moves backward, and the cylinder 3 moves directly above the electronic pump body 6. The cylinder 3 extends, bringing the laser detector 31 closer to the stator 7.
[0041] A thin rubber ring 22 is provided on the inner wall of the conveying channel 21. The upper edge of the thin rubber ring 22 is fixedly bonded to the inner wall of the conveying channel 21. The diameter of the thin rubber ring 22 is larger at the top and smaller at the bottom. The lower end of the thin rubber ring 22 covers the upper end of the electric push rod 26. This prevents the stator 7 from touching and getting stuck with the electric push rod 26, and facilitates the stator 7 to slide down between the four electric push rods 26.
[0042] The fixing assembly 5 includes two connecting plates 51, two arc-shaped housings 52, a second electric actuator 53, a small motor 54, and two electromagnet modules 55. The two arc-shaped housings 52 are located between the two connecting plates 51, and the two arc-shaped housings 52 are close together. The upper ends of the arc-shaped housings 52 are hinged to the connecting plates 51. The electromagnet modules 55 are fixedly installed inside the arc-shaped housings 52. The two arc-shaped housings 52 cover the second electric actuator 53. The lower ends of the small motor 54 and the second electric actuator 53 are fixedly installed together with the small motor 54. The upper ends of the second electric actuator 53 extend outside the arc-shaped housings 52.
[0043] The small motor 54 has a vertically downward-facing drive shaft connected to a hexagonal column, which is connected to the top of the screw 10. The electric actuator 2 53 is arranged vertically.
[0044] The arc-shaped housing 52 is beak-shaped. When the electromagnet module 55 is energized, it generates a magnetic field that attracts the two arc-shaped housings 52, causing the lower end of the arc-shaped housings 52 to clamp the screw 10 rod. During operation, the electric actuator 53 extends while the small motor 54 rotates, causing the screw 10 to rotate and be screwed into the screw hole, thus fixing the stator 7, exhaust plate 8, and electronic pump body 6 together.
[0045] A slide rail 15 is suspended above the base 1. The top of the mounting box 2 and the cylinder 3 are both fixedly installed with drive components. The drive components are slidably engaged with the slide rail 15. A slide rail 2 16 is suspended on the outside of the slide rail 15. A movable seat 4 is slidably engaged with the slide rail 2 16. A large motor is fixedly installed at the bottom of the movable seat 4. A support rod 41 is fixedly installed with the transmission shaft of the large motor facing downward. The upper end of the connecting plate 51 and the upper end of the electric push rod 2 53 are both welded to the lower end of the support rod 41.
[0046] When installing stator 7 and performing spacing testing, see attached... Figure 2 As shown, if the stator 7 is installed correctly and the test is successful, the exhaust plate 8 is placed on the stator 7. The fixing component 5 passes the screw 10 through the holes of the stator 7 and the exhaust plate 8, and screws it into the screw hole at the top of the electric pump to assemble the stator 7, the exhaust plate 8, and the electric pump body 6 together.
[0047] A flipping mechanism 11 is fixedly installed on the top of the base 1. A crossbar 12 is hinged to the flipping mechanism 11. An air suction pipe 13 is connected to the end of the crossbar 12 away from the flipping mechanism 11. The air suction pipe 13 can draw air to adsorb the exhaust plate 8. When the detection is correct, the crossbar 12 drives the exhaust plate 8 to flip and cover the exhaust plate 8 on the stator 7.
[0048] A clamping block 14 is fixedly installed on the top of the base 1. The clamping block 14 is used to clamp the electronic pump body 6.
[0049] In summary, this semi-automatic assembly and testing machine for vacuum electronic pump parts includes a placement box 2, a cylinder 3, and a fixing component 5. The placement box 2 is used to transport the stator 7 and place it over the rotor 9, replacing the traditional manual placement method and speeding up the assembly of the electronic pump. A laser detector 31 is installed at the bottom of the cylinder 3 to detect the apex of the inner wall of the stator 7 using a laser. Based on whether the apex of the inner wall of the stator 7 touches the laser, it is determined whether there is a deviation in the placement position of the stator 7. A crossbar 12 is also included.
[0050] Furthermore, the fixing component 5 consists of two arc-shaped housings 52, an electric push rod 53, a small motor 54, and an electromagnet module 55. The electromagnet module 55 generates a magnetic field when energized, which causes the lower ends of the two arc-shaped housings 52 to move closer to each other, thereby clamping the screw 10 at the lower end of the arc-shaped housings and preventing the screw 10 from falling off during the movement of the fixing component 5 carrying the screw 10.
[0051] Secondly, four electric push rods 26 are slidably fitted at the bottom of the mounting box 2. The lower end of the electric push rods 26 is connected to a shovel 261, which serves to support the stator 7. The electric push rods 26 extend and contact the top of the electronic pump body 6, so that the stator 7 is fitted over the rotor 9. This replaces manual placement and improves accuracy. The exhaust plate 8 is covered by a crossbar 12 and pressed down on the stator 7 to prevent the parts from sliding during the fixing process of the screws 10, thus achieving the purpose of assembling the parts together.
[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
