Description

Technical Field

[0001] This application relates to the field of air compressor assembly equipment, and in particular to a rotary assembly machine for assembling main units. Background Technology

[0002] An air compressor is a mechanical device that compresses the volume of gas, increases the gas pressure, and transports the gas. According to its working principle, air compressors are divided into positive displacement type and dynamic type. Positive displacement type can be divided into three types: piston type, screw type, and vane type; dynamic type can be divided into two types: centrifugal type and axial flow type.

[0003] For screw air compressors, the main components are the screw compressor unit and the drive motor. During the assembly of large screw air compressors, the output shaft of the drive motor needs to be coaxially connected to the input shaft of the screw compressor unit.

[0004] For large screw air compressors, the traditional assembly method involves workers directly assembling the compressor and drive motor using hoisting equipment. During assembly, workers need to rely on their experience to adjust the position of the screw compressor or drive motor. However, due to the large size and weight of the screw compressor and drive motor, even slight swaying of the hoisting equipment during hoisting can cause significant deviations in their connection positions. Therefore, the traditional assembly method requires repeated adjustments to their positions, resulting in a long assembly time and safety hazards during hoisting. Summary of the Invention

[0005] In order to improve the problems of traditional assembly methods, this application provides a rotary assembly machine for main unit assembly.

[0006] The rotary assembly machine for main unit assembly provided in this application adopts the following technical solution: A rotary assembly machine for main unit assembly includes a base plate, an indicator frame, and an indicator axis. One end of the base plate is provided with an end seat. A support plate is vertically slidably mounted on the end seat.

A secondary plate is rotatably mounted on the docking seat. A second rotating component is provided on the docking seat to drive the secondary plate to rotate. The moving part, the drive motor, is used to place it on the secondary plate. The indicator component includes a three-jaw chuck, a laser emitter, and a first camera. The laser emitter is disposed on the axis of the three-jaw chuck. Multiple first cameras are evenly distributed circumferentially on the three-jaw chuck. The first cameras are electrically connected to the control system. The indicator frame is located between the end seat and the docking seat. The indicator frame is detachably disposed on the base plate. A standard plate is slidably disposed on the indicator frame. A center point is disposed on the standard plate. The laser emitted by the laser emitter is used to vertically point to the center point. A follower component is disposed on the indicator frame to drive the standard plate to move in the vertical plane.

[0007] Optionally, the standard plate includes a vertical plate and a horizontal plate, the horizontal plate is symmetrically arranged on both sides of the vertical plate, the axis point is set on both sides of the vertical plate, and the horizontal plate is provided with angle scale lines.

[0008] Optionally, the accompanying component includes two second cameras mounted on the indicator frame. The second cameras are located directly above the horizontal plate, and each second camera corresponds to one of the horizontal plates. The second cameras are electrically connected to the control system and are used to photograph the horizontal plate. The indicator frame is equipped with a first linear module, and a support frame is mounted on the slider of the first linear module. The standard plate is vertically slidably mounted on the support frame. A vertical hydraulic cylinder electrically connected to the control system is mounted on the support frame, and the standard plate is mounted on the piston rod of the vertical hydraulic cylinder. The sliding direction of the support frame is perpendicular to the direction of the docking seat near the end seat.

[0009] Optionally, the lifting component includes multiple lifting cylinders disposed on the end seat, the bearing plate is disposed on the piston rod of the lifting cylinder, and the lifting cylinder is electrically connected to the control system.

[0010] Optionally, the first rotating component includes a first rotary motor disposed on the support plate, the first rotary motor being electrically connected to the control system, and a first bearing being disposed between the main plate and the support plate.

[0011] Optionally, the sliding assembly includes a base plate slidably disposed on the substrate, a multi-stage hydraulic cylinder electrically connected to the control system is disposed on the substrate, the base plate is disposed on the piston rod of the multi-stage hydraulic cylinder, a slide rail and a second linear module are disposed on the base plate, a docking seat is slidably disposed on the slide rail, the docking seat is disposed on the slider of the second linear module, and the axial direction of the multi-stage hydraulic cylinder is perpendicular to the length direction of the slide rail.

[0012] Optionally, the second rotating component includes a second rotary motor disposed on the docking seat, the secondary plate is disposed on the output shaft of the second rotary motor, and a second bearing is disposed between the docking seat and the secondary plate.

[0013] By adopting the above technical solution, workers first use hoisting equipment to initially hoist the screw main unit onto the main plate and the drive motor onto the secondary plate. Then, the indicator frame is installed on the base plate. Simultaneously, a three-jaw chuck is fixed to both the input shaft of the screw main unit and the output shaft of the drive motor. At this point, the laser emitted by the laser emitter on the three-jaw chuck on the input shaft of the screw main unit will illuminate the vertical plate. The second camera will feed back the projection of the laser emitted by the laser emitter corresponding to the screw main unit onto the horizontal plate to the control system. The control system starts the first rotary motor, and the output shaft of the first rotary motor drives the support plate to rotate, thereby causing the laser emitted by the laser emitter corresponding to the screw main unit to be vertically projected onto the vertical plate. Subsequently, guided by the first camera, the first linear module drives the standard plate to move horizontally via the upright frame, and the vertical cylinder drives the standard plate to move vertically, thereby causing the laser emitted by the laser emitter corresponding to the screw main unit to illuminate the axis point on the vertical plate. Afterwards, the laser emitted by the three-jaw chuck on the output shaft of the drive motor... The laser emitted by the emitter also illuminates the vertical plate. The second camera feeds back the projection of the laser emitted by the laser emitter corresponding to the drive motor onto the horizontal plate to the control system. The control system then starts the second rotary motor, which drives the secondary plate to rotate, so that the laser emitted by the laser emitter corresponding to the drive motor is perpendicularly projected onto the vertical plate. Afterward, the second linear module drives the docking seat to slide, so that the position of the laser emitted by the laser emitter corresponding to the drive motor on the vertical plate is in the vertical direction of the axis point. Then, the control system starts the vertical cylinder and the lifting cylinder, so that the standard plate and the carrier plate slide vertically synchronously, thereby pointing the laser emitted by the laser emitter corresponding to the drive motor to the axis point on the vertical plate, thus completing the automatic alignment of the screw host and the drive motor axis. Subsequently, the indicator frame and the three-jaw chuck are removed, and the docking seat is brought close to the end seat by the multi-stage cylinder to complete the assembly of the screw host and the drive motor. This process greatly improves the efficiency and safety of the assembly of the screw host and the drive motor.

[0014] Optionally, the indicator frame has a U-shaped cross-section, one end of the indicator frame is threaded with a fastening screw, the end of the fastening screw near the substrate is rotatably provided with an abutment plate, and the end of the fastening screw away from the substrate is provided with a handle.

[0015] By adopting the above technical solution, the worker first fastens the U-shaped concave side of the indicator frame to the top of the substrate, and then rotates the handle to make the fastening screw drive the abutment plate to abut against the side of the substrate. As the fastening screw rotates continuously, the indicator frame will automatically align and be fixed on the substrate, so that the sliding direction of the slider of the first linear module is perpendicular to the sliding direction of the docking seat. This method is simple and convenient.

[0016] In summary, this application includes at least one of the following beneficial technical effects: A three-jaw chuck is fixed on both the input shaft of the screw host and the output shaft of the drive motor. At this time, the laser emitted by the laser emitter on the three-jaw chuck on the input shaft of the screw host will illuminate the vertical plate. The second camera will feed back the projection of the laser emitted by the laser emitter corresponding to the screw host onto the horizontal plate to the control system. The control system starts the first rotary motor, and the output shaft of the first rotary motor drives the bearing plate to rotate, so that the laser emitted by the laser emitter corresponding to the screw host is perpendicularly projected onto the vertical plate. Guided by the first camera, the first linear module moves the standard plate horizontally via the upright frame, and the vertical cylinder moves the standard plate vertically, so that the laser emitted by the laser emitter corresponding to the screw host illuminates the axis point on the vertical plate. Then, the laser emitted by the laser emitter on the three-jaw chuck on the output shaft of the drive motor also illuminates the vertical plate. The second camera feeds back the projection of the laser emitted by the laser emitter corresponding to the drive motor onto the horizontal plate to the control system. The control system starts the second rotary motor, which drives the secondary plate to rotate, so that the laser emitted by the laser emitter corresponding to the drive motor is vertically projected onto the vertical plate. The second linear module drives the docking seat to slide, so that the laser emitted by the laser emitter corresponding to the drive motor is positioned on the vertical plate at the axis point. Then, the control system activates the vertical cylinder and the lifting cylinder, so that the standard plate and the support plate slide vertically synchronously, thereby pointing the laser emitted by the laser emitter corresponding to the drive motor to the axis point on the vertical plate, thus completing the automatic alignment of the screw host and the drive motor axis. Then, the indicator frame and the three-jaw chuck are removed, and the docking seat is brought closer to the end seat by the multi-stage cylinder to complete the assembly of the screw host and the drive motor.

[0031] Workers first use hoisting equipment to initially hoist the screw host 1 onto the main plate 9 and the drive motor 2 onto the secondary plate 13. Then, multiple first anti-slip blocks 22 are installed on the first slide groove 21 on the main plate 9, so that the bottom of the screw host 1 abuts against a first anti-slip block 22 on all four sides. Multiple second anti-slip blocks 24 are installed on the second slide groove 23 on the secondary plate 13, so that the bottom of the drive motor 2 abuts against a second anti-slip block 24 on all four sides.

Both the laser emitter 52 and the first camera 53 are electrically connected to the control system via wires.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The indicator frame 4 is located between the end seat 6 and the docking seat 11. The cross-section of the indicator frame 4 is U-shaped. One end of the indicator frame 4 is threaded with a fastening screw 18. The end of the fastening screw 18 near the base plate 3 is rotatably connected to an abutment plate 19. The end of the fastening screw 18 away from the base plate 3 is bolted with a handle 20. A standard plate 15 is slidably arranged on the indicator frame 4. A pivot point 16 is arranged on the standard plate 15.

[0034] The worker fixes a three-jaw chuck 51 on the input shaft of the screw host 1 and the output shaft of the drive motor 2, and supplies power to the laser emitter 52 and the first camera 53. Then, the indicator frame 4 is clipped onto the top of the substrate 3. After that, the handle 20 is turned, which drives the fastening screw 18 to rotate in the forward direction, so that the abutment plate 19 abuts against the side wall of the substrate 3, thereby realizing the installation and fixation of the indicator frame 4.

[0035] Reference Figure 1 , Figure 2 and Figure 3The standard plate 15 includes a vertical plate 151 and a horizontal plate 152. The horizontal plate 152 is symmetrically arranged on both sides of the vertical plate 151. The axis point 16 is arranged on both sides of the vertical plate 151. The horizontal plate 152 is arranged with fan-shaped angle scale lines 153. The laser emitted by the laser emitter 52 is used to vertically point to the axis point 16. The indicator frame 4 is equipped with a standard component 17 that drives the standard plate 15 to move in the vertical plane.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The accompanying component 17 includes two second cameras 171 arranged on the indicator frame 4. The second cameras 171 are located directly above the horizontal plate 152. The second cameras 171 correspond one-to-one with the horizontal plate 152. The second cameras 171 are electrically connected to the control system. The second cameras 171 are used to photograph the horizontal plate 152. A first linear module 172 is attached to the indicator frame 4.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The first linear module 172 can be a ball screw linear module in the prior art. A stand 173 is bolted to the slider of the first linear module 172. The second camera 171 is bolted to the stand 173. The standard plate 15 is vertically slidably set on the stand 173. A vertical cylinder 174 electrically connected to the control system is bolted to the stand 173. The standard plate 15 is bolted to the piston rod of the vertical cylinder 174. The sliding direction of the stand 173 is perpendicular to the direction of the docking seat 11 near the end seat 6.

[0038] The laser emitted by the laser emitter 52 on the three-jaw chuck 51 on the input shaft of the screw host 1 will illuminate the vertical plate 151. The second camera 171 will feed back the projection of the laser emitted by the laser emitter 52 corresponding to the screw host 1 onto the horizontal plate 152 to the control system. The control system starts the first rotary motor 101. The output shaft of the first rotary motor 101 drives the bearing plate 7 to rotate, and the bearing plate 7 drives the screw host 1 to rotate synchronously.

[0039] This allows the laser emitted by the laser emitter 52 corresponding to the screw host 1 to be projected vertically onto the vertical plate 151. Subsequently, under the guidance of the first camera 53, the first linear module 172 drives the standard plate 15 to move horizontally via the stand 173, and the vertical cylinder 174 drives the standard plate 15 to move vertically, thereby causing the laser emitted by the laser emitter 52 corresponding to the screw host 1 to irradiate the axis point 16 on the vertical plate 151.

[0040] Subsequently, the laser emitted by the laser emitter 52 on the three-jaw chuck 51 on the output shaft of the drive motor 2 will also illuminate the vertical plate 151. The second camera 171 will feed back the projection of the laser emitted by the laser emitter 52 corresponding to the drive motor 2 onto the horizontal plate 152 to the control system. The control system will start the second rotary motor 141, which will drive the secondary plate 13 to rotate, so that the laser emitted by the laser emitter 52 corresponding to the drive motor 2 will be vertically projected onto the vertical plate 151.

[0041] Subsequently, guided by the first camera 53 on the three-jaw chuck 51 on the output shaft of the drive motor 2, the second linear module 124 drives the docking seat 11 to slide, thereby causing the laser emitted by the laser emitter 52 corresponding to the drive motor 2 to be positioned on the vertical plate 151 in the vertical direction of the axis point 16. At the same time, the first camera 53 on the three-jaw chuck 51 on the output shaft of the drive motor 2 will feed back the position of the laser emitted by the laser emitter 52 corresponding to the drive motor 2 on the vertical plate 151 to the control system.

[0042] The control system activates the vertical cylinder 174 and the lifting cylinder 8, thereby causing the standard plate 15 and the support plate 7 to slide vertically synchronously. This causes the laser emitted by the laser emitter 52 corresponding to the drive motor 2 to point to the axis point 16 on the vertical plate 151, thus completing the automatic alignment of the axis of the screw host 1 and the drive motor 2.

[0043] Subsequently, the indicator bracket 4 and the three-jaw chuck 51 are removed, and the docking seat 11 is brought close to the end seat 6 by the multi-stage hydraulic cylinder 122 to complete the assembly of the screw host 1 and the drive motor 2. This process greatly improves the efficiency and safety of the assembly of the screw host 1 and the drive motor 2.

[0044] The implementation principle of a rotary assembly machine for main unit assembly in this application embodiment is as follows: the worker first hoists the screw main unit 1 onto the main plate 9 using hoisting equipment, and then hoists the drive motor 2 onto the secondary plate 13. Then, multiple first anti-slip blocks 22 are installed on the first slide groove 21 on the main plate 9, so that the bottom of the screw main unit 1 abuts against a first anti-slip block 22 on all four sides. Multiple second anti-slip blocks 24 are installed on the second slide groove 23 on the secondary plate 13, so that the bottom of the drive motor 2 abuts against a second anti-slip block 24 on all four sides, thereby fixing the screw main unit 1 and the drive motor 2.

[0045] The worker fixes a three-jaw chuck 51 on the input shaft of the screw host 1 and the output shaft of the drive motor 2, and supplies power to the laser emitter 52 and the first camera 53. Then, the indicator frame 4 is clipped onto the top of the substrate 3. After that, the handle 20 is turned, which drives the fastening screw 18 to rotate in the forward direction, so that the abutment plate 19 abuts against the side wall of the substrate 3, thereby realizing the installation and fixation of the indicator frame 4.

[0046] The laser emitted by the laser emitter 52 on the three-jaw chuck 51 on the input shaft of the screw host 1 will illuminate the vertical plate 151. The second camera 171 will feed back the projection of the laser emitted by the laser emitter 52 corresponding to the screw host 1 onto the horizontal plate 152 to the control system. The control system starts the first rotary motor 101. The output shaft of the first rotary motor 101 drives the bearing plate 7 to rotate, and the bearing plate 7 drives the screw host 1 to rotate synchronously.

[0047] This allows the laser emitted by the laser emitter 52 corresponding to the screw host 1 to be projected vertically onto the vertical plate 151. Subsequently, under the guidance of the first camera 53, the first linear module 172 drives the standard plate 15 to move horizontally via the stand 173, and the vertical cylinder 174 drives the standard plate 15 to move vertically, thereby causing the laser emitted by the laser emitter 52 corresponding to the screw host 1 to irradiate the axis point 16 on the vertical plate 151.

[0048] Subsequently, the laser emitted by the laser emitter 52 on the three-jaw chuck 51 on the output shaft of the drive motor 2 will also illuminate the vertical plate 151. The second camera 171 will feed back the projection of the laser emitted by the laser emitter 52 corresponding to the drive motor 2 onto the horizontal plate 152 to the control system. The control system will start the second rotary motor 141, which will drive the secondary plate 13 to rotate, so that the laser emitted by the laser emitter 52 corresponding to the drive motor 2 will be vertically projected onto the vertical plate 151.

[0049] Subsequently, guided by the first camera 53 on the three-jaw chuck 51 on the output shaft of the drive motor 2, the second linear module 124 drives the docking seat 11 to slide, thereby causing the laser emitted by the laser emitter 52 corresponding to the drive motor 2 to be positioned on the vertical plate 151 in the vertical direction of the axis point 16. At the same time, the first camera 53 on the three-jaw chuck 51 on the output shaft of the drive motor 2 will feed back the position of the laser emitted by the laser emitter 52 corresponding to the drive motor 2 on the vertical plate 151 to the control system.

[0050] The control system activates the vertical cylinder 174 and the lifting cylinder 8, thereby causing the standard plate 15 and the support plate 7 to slide vertically synchronously. This causes the laser emitted by the laser emitter 52 corresponding to the drive motor 2 to point to the axis point 16 on the vertical plate 151, thus completing the automatic alignment of the axis of the screw host 1 and the drive motor 2.

[0051] Subsequently, the indicator bracket 4 and the three-jaw chuck 51 are removed, and the docking seat 11 is brought close to the end seat 6 by the multi-stage hydraulic cylinder 122 to complete the assembly of the screw host 1 and the drive motor 2. This process greatly improves the efficiency and safety of the assembly of the screw host 1 and the drive motor 2.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
