Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning compressors, and in particular to a lightweight air-conditioning compressor assembly and a method thereof. Background Art

[0002] The air conditioning compressor is the core component of the air conditioning system. It is responsible for sucking low-temperature and low-pressure refrigerant from the evaporator, compressing it into high-temperature and high-pressure gas, and then transporting it to the condenser, thereby realizing the cooling function of the air conditioning system. At present, most of the vehicle air conditioning compressor components adopt lightweight structures to reduce the weight of the vehicle body and reduce energy consumption.

[0003] When installing the vehicle-mounted lightweight air-conditioning compressor assembly, it is necessary to first fix it to the frame with screws, and then use a robotic arm to tighten the screws and detect the size of the locking force to prevent the compressor from loosening due to vibrations generated during driving, thereby avoiding safety risks.

[0004] When existing lightweight air-conditioning compressor assemblies are tightened and tested, transmission is mostly achieved by the first motor driving the sleeve to rotate. This solution is not convenient for adjusting the rotation speed and torque of the sleeve. During the tightening process, a slow rotation speed will increase the time spent and reduce the installation efficiency. Therefore, the rotation speed needs to be increased. At the same time, a higher torque is required to increase the rotation speed. During the detection process, a large torque can easily cause the screws to fall off, affecting the installation quality and detection accuracy. Therefore, this solution needs to be improved.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figures 1 to 13 As shown: A lightweight air-conditioning compressor assembly includes a conveyor belt, which is used to convey an engine frame and a compressor body. The bolt holes on the compressor body are aligned with the bolt holes on the engine frame and fit together. The bolt bodies are then passed through the bolt holes and the engine frame is placed on the conveyor belt. The conveyor belt is operated to convey the engine frame to the bottom of the installation assembly, thereby completing the preparation work for lightweight installation inspection. The invention also includes an installation detection component, a torque adjustment component and a linkage locking component. The installation component includes a mechanical arm, a pair of support plates, multiple bolt sleeves, a first motor, a torque sensor, a transmission mechanism and multiple penetration protection mechanisms. The mechanical arm can be installed on the conveyor belt horizontally and rotatably. The mechanical arm is used to drive the support plate to move. The two support plates are fixedly connected to each other. The top of the bolt sleeve passes through the bottom support plate and is rotatably connected thereto. The first motor can be installed on the top support plate horizontally and movably. The first motor drives multiple bolt sleeves to rotate synchronously through the torque adjustment component and the transmission mechanism. The torque sensor is installed on the transmission mechanism. The torque sensor is used to detect the rotational friction force exerted on the bolt body. The penetration protection mechanism is installed on the bolt sleeve. The penetration protection mechanism is used to detect whether the bolt body is inserted into the bolt hole. The mechanical arm drives the support plate to move above the compressor body and aligns the bottoms of multiple bolt sleeves with multiple bolt bodies respectively. Multiple bolt bodies can be tightened simultaneously through the transmission mechanism to improve installation efficiency. Then the robotic arm is lowered, and the bolt sleeve is sleeved on the outer periphery of the bolt body. The first motor is first rotated to drive the bolt sleeve to rotate in the forward direction, so that the bolt body can be tightened to complete the lightweight installation. Then the first motor is driven to drive the bolt sleeve to rotate in the reverse direction. The torque sensor is used to detect whether the torque size meets the requirements. The tightness of the bolt body installation can be detected to ensure stable installation. The torque adjustment assembly includes a first bevel gear, a driving gear and a friction resistance increasing mechanism. The first bevel gear can be vertically rotatably installed on the top support plate. The driving gear is coaxially connected to the output shaft of the first motor, the driving gear is meshed with the first bevel gear, the diameter of one end of the first bevel gear is larger than the diameter of the other end, and the first bevel gear is coaxially connected to the input end of the transmission mechanism. The driving gear is driven by the first motor to move horizontally, so that the driving gear is meshed with different positions on the first bevel gear under different working conditions. When the diameter of the driving gear is larger than the diameter of the contact position of the first bevel gear, the bolt sleeve has a faster speed and a larger torque, and the bolt can be tightened quickly. Otherwise, the speed decreases and the torque is smaller. When detecting the size of the bolt tightening force, the bolt can be prevented from loosening, thereby improving the detection accuracy and installation quality of the lightweight installation of the compressor body. The linkage locking assembly is installed on the conveyor belt, and the linkage locking assembly is used to lock the conveyor belt to prevent the compressor body from moving when the installation detection assembly is working.

[0038] like Figures 1 to 9 As shown: The torque adjustment assembly also includes a pair of rotating seats, a rotating rod, a slide rail, an electric slider and a support seat. The rotating seat and the slide rail are fixedly installed on the top of the support plate. The two ends of the rotating rod are respectively rotatably connected to the two rotating seats. The outer periphery of the rotating rod is coaxially connected to the first bevel gear. When the first bevel gear is subjected to force, the rotating rod can be rotated between the two rotating seats to realize transmission. The outer periphery of the top of the slide rail is slidably connected to the electric slider, the bottom of the support seat is fixedly connected to the top of the electric slider, one end of the first motor is fixedly connected to the support seat, and the output shaft of the first motor passes through the support seat and is rotatably connected to it. The electric slider is powered on to drive the support seat to move along the slide rail, so as to realize the horizontal movement of the first motor and the driving gear, thereby controlling the driving gear to engage with the two ends of the first bevel gear respectively, so as to achieve the purpose of adjusting the speed and torque of the bolt sleeve.

[0039] 3. Figures 1 to 10 As shown: The friction resistance increasing mechanism includes a friction wheel, an extrusion block, an insertion rod, a tension spring and a lifting rod. The friction wheel is coaxially connected to the outer periphery of the rotating rod. The bottom of the extrusion block is fixedly connected to the top of the insertion rod. The insertion rod can be vertically slidably installed on the top support plate. The tension spring is installed on the insertion rod. The tension spring is used to provide a vertical downward pulling force to the insertion rod. One end of the lifting rod is fixedly connected to the support seat. An empty slot is provided at one end of the insertion rod. The other end of the lifting rod is an inclined surface structure and is plugged into the empty slot. When the support seat is close to the end with a larger diameter of the first bevel gear, one end of the lifting rod is inserted into the empty slot and the insertion rod is lifted upward, so that the extrusion block and the friction wheel conflict with each other, thereby further reducing the torque of the bolt sleeve on the bolt during detection and improving stability. When the support seat is away from the end with a larger diameter of the first bevel gear, the insertion rod moves downward through the tension provided by the tension spring, so that the extrusion block is separated from the friction wheel to prevent resistance from being generated when tightening the bolt body.

[0040] like Figures 1 to 10 As shown: The tension spring is sleeved around the outer periphery of the plug rod, the bottom of the plug rod passes through the top support plate and is slidably connected to it, one end of the tension spring is fixedly connected to the plug rod, and the other end of the tension spring is fixedly connected to the top of the top support plate. When the plug rod is lifted up, the tension spring is stretched, and when the lifting rod is separated from the empty slot, the tension spring rebounds to provide tension to make the plug rod slide vertically downward, driving the extrusion block to separate from the friction wheel.

[0041] 5. Figures 1 to 12 As shown: The transmission mechanism includes a pair of second bevel gears, a pair of rotating shafts, a first spur gear and multiple transmission gears, wherein one of the second bevel gears is the input end of the transmission mechanism and is coaxially connected to the top of one of the rotating shafts, the rotating rod passes through one of the rotating seats and is coaxially connected to the other second chasing gear, the two second bevel gears are meshed with each other, the top of the other rotating shaft passes through the first spur gear and is coaxially connected thereto, the bottom of the top rotating shaft passes through the top supporting plate and is rotatably connected thereto, the bottom of the bottom rotating shaft is rotatably connected to the bottom supporting plate, one side of the torque sensor is fixedly connected to the top supporting plate, the input shaft and output shaft of the torque sensor are coaxially connected to the two rotating shafts respectively, the transmission gear is meshed with the first spur gear, the top of the bolt sleeve passes through the bottom supporting plate and is rotatably connected thereto, and the transmission gear is connected to the outer periphery of the top of the bolt sleeve through a leakage protection mechanism. When the rotating rod rotates, it drives one of the second bevel gears to rotate, and through the meshing transmission between the two second bevel gears, drives the top rotating shaft to rotate. The driving force is transmitted to the bottom rotating shaft through the torque sensor, so that it drives the first spur gear to rotate and detects the size of the torque. At the same time, through the meshing transmission between the first spur gear and the transmission gear, it drives multiple bolt sleeves to rotate and tighten the bolt body.

[0042] like Figures 1 to 12 As shown: The leakage protection mechanism includes a pair of protrusions, a pair of reset springs and a pair of connecting rods. The bottom of the connecting rod is fixedly connected to the protrusions. A pair of slide grooves are provided inside the bolt sleeve. The two slide grooves are symmetrically arranged inside the bolt sleeve. The slide grooves are connected to the inside of the bolt sleeve. The connecting rod and the protrusions are slidably connected to the slide grooves. A pair of card slots are provided on the inner wall of the transmission gear. The card slots are plugged and matched with the top of the connecting rod. The two ends of the reset spring are respectively fixedly connected to the two connecting rods. When the bolt body slides into the bolt sleeve, the two protrusions are squeezed to both sides to drive the connecting rod to slide into the slide groove. At this time, the reset spring is stretched, and the top of the connecting rod is plugged and matched with the card slot, so that the bolt sleeve is coaxially connected with the transmission gear. When the bolt body is separated from the bolt sleeve, the reset spring rebounds and drives the two protrusions to slide out of the slide groove, and the top of the connecting rod is separated from the card slot. When the staff makes an error in operation and fails to insert the bolt body into the bolt hole, the bolt sleeve cannot keep synchronous rotation with the transmission gear. At this time, the torque detected by the torque sensor is different from the normal value, thereby reminding the operator of leakage.

[0043] like Figures 1 to 5 As shown: The conveyor belt includes a base, a shell, a conveyor belt, a pair of transmission shafts and a second motor. The bottom of the shell is fixedly connected to the top of the base, the two ends of the transmission shaft are respectively rotatably connected to the inner walls of the shell, the conveyor belt is sleeved on the outer periphery of the transmission shaft, one side of the second motor is fixedly connected to the shell, and the output shaft of the second motor passes through the side wall of the shell and is coaxially connected to one of the transmission shafts. When the second motor is powered on to work, one of the transmission shafts is driven to rotate, thereby driving the other transmission shaft and the conveyor belt to rotate, so that the compressor body on the conveyor belt can be transported.

[0044] like Figures 1 to 13 As shown: The mechanical arm includes a housing, a rotating column, a third motor, a guide rail, an electric slide and a hydraulic rod. The rotating column passes through the housing and is rotatably connected thereto. One end of the guide rail is fixedly connected to the top of the rotating column. The electric slide is slidably connected to the outer periphery of the guide rail. The top of the hydraulic rod is fixedly connected to the electric slide rail. The telescopic end of the hydraulic rod passes through the top support plate and is fixedly connected thereto. One side of the base is fixedly connected with a support frame. The housing passes through the top wall of the support frame and is fixedly connected thereto. The top of the third motor is fixedly connected to the bottom of the support frame. The output shaft of the third motor passes through the bottom wall of the support frame and is coaxially connected to the bottom of the rotating column. The support frame is used to support the mechanical arm. By setting the third motor to drive the rotating column to rotate, the direction of the mechanical arm can be adjusted to prevent obstruction to the delivery of the compressor body. By setting the electric slide and the guide rail, the position of the support plate can be adjusted so that the bolt sleeve is aligned with the bolt body. By setting the hydraulic rod, the support plate can be driven to move up and down, so that the top of the bolt body is inserted into the bolt sleeve, and downward pressure can be provided to the bolt body for fastening.

[0045] like Figures 1 to 13 As shown: The linkage locking assembly includes a second spur gear, a rack, a limit rod and a limit gear. The second spur gear is coaxially connected to the outer periphery of the rotating column, the rack is meshed with the second spur gear, one end of the limit rod is fixedly connected to the rack, the limit rod passes through the side wall of the shell and is slidably connected thereto, the limit gear is coaxially connected to the outer periphery of the transmission shaft, and the other end of the limit rod is engaged with the limit gear. When the mechanical arm rotates to the top of the compressor body, the second spur gear rotates with the rotating column, and through the meshing transmission between the second spur gear and the rack, it drives the limit rod to slide horizontally, and engages with the limit gear, so that the limit gear is locked, thereby preventing the transmission shaft from rotating, and avoiding the displacement of the compressor body due to the conveyor belt operation caused by misoperation during the lightweight installation and detection process.

[0046] The present embodiment also provides a method for lightweighting an air-conditioning compressor assembly, comprising the following steps: step one: first align the bolt holes on the compressor body with the bolt holes on the engine frame and fit them together, then pass the bolt body through the bolt holes and place the engine frame on a conveyor belt, and transport the compressor body through the provided conveyor belt; step two: a mechanical arm is installed on one side of the conveyor belt, which can drive the installation detection assembly to move to the top of the compressor body, so that the bolt sleeve is outside the outer periphery of the bolt body, and at the same time, the conveyor belt is locked through the provided linkage locking assembly to prevent the compressor assembly from shifting; step three: an installation detection assembly is installed on the mechanical arm, which can tighten and detect multiple bolt bodies at the same time; step four: a leakage protection assembly is provided in the bolt sleeve, which cooperates with the torque sensor in the installation detection assembly, so that the staff can find out in time when the bolt body is leaked; step five: the torque adjustment assembly provided on the support plate can change the speed and torque output by the installation detection assembly, thereby increasing the speed when tightening the bolts and improving the efficiency, and reducing the torque when detecting the tightness and improving the stability.

[0047] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not limiting, but are only for the convenience of clearly describing the positional relationship and function between the various components.
