Description

Technical Field

[0001] The invention relates to the field of automobile stator processing, and in particular to a retarder stator sorting system. Background Art

[0002] The automobile retarder is to energize the excitation coil of the stator assembly through the control circuit to generate a magnetic field. The rotor assembly rotates at high speed with the vehicle transmission part, cutting the magnetic lines of force, generating a reverse torque to slow down the vehicle. According to the different working principles, the automobile retarder can be divided into typical structural forms such as engine retarder, hydraulic retarder, electric turbine retarder, motor retarder and aerodynamic retarder. According to the different forms of braking torque, the automobile retarder can be divided into a primary retarder (a retarder acting on the front end of the gearbox) and a secondary retarder (a retarder acting on the rear end of the gearbox).

[0003] As a vehicle auxiliary braking device, the hydraulic retarder is widely used in large and medium-sized vehicles because it can provide continuous and wear-free braking torque for the vehicle, providing an important guarantee for the safe driving of the vehicle. The working chamber of the hydraulic retarder is mainly composed of a rotor and a stator, wherein the stator is fixed on the housing of the hydraulic retarder, and the rotor is connected to the transmission shaft of the vehicle. The working fluid inlet of the hydraulic retarder is arranged in the middle of the stator blade, and the working fluid outlet is arranged on the outside of the circulation circle, and the stator must have at least one blade with an air hole. During the driving process of the vehicle, the rotor rotates with the transmission shaft. When the hydraulic retarder needs to output torque, the working fluid enters the working chamber from the working fluid inlet, and the gas in the working chamber is discharged through the air hole. The working fluid outputs torque through the action of the rotor and the stator, thereby adjusting the vehicle speed. Therefore, three channels are required during the working process of the hydraulic retarder, namely the intake and exhaust channel, the working fluid inlet channel and the working fluid outlet channel.

[0004] At present, in the process of stator processing in the hydraulic retarder, since it involves the circulation of working fluid when working, and the stator, as one of the components of the hydraulic retarder, is also a transition component for the circulation of working fluid, therefore, it is also necessary to open corresponding oil holes on the stator to facilitate the circulation of working fluid. After the oil holes are opened on the stator, the oil resistance of the oil holes is different due to the different aperture sizes of the oil holes. In the subsequent packaging, it is necessary to classify and package according to different oil resistances. The existing packaging method is: first send a batch of stator finished products to the oil resistance test process to detect the oil resistance of the stator oil hole, then the staff will code and mark the stator according to the test results, put it on a turnover vehicle for turnover, and manually transfer the turnover vehicle to the cleaning process to clean the oil remaining in the stator, and then manually classify and pack it according to different marks on the stator surface. The whole packaging process requires a lot of manpower and material resources, the labor intensity is high, and the work efficiency is low. Moreover, in the process of manual testing and coding, deviations are prone to occur, that is, the actual coding is inconsistent with the test results. Summary of the invention

When connecting, Place two T-bolts in the T-shaped mounting guide groove 65 of the spray terminal mounting column 63 in advance, then align the two mounting holes of the first connecting plate 64 with the two T-bolts, put the first connecting plate 64 on the T-bolts, and then use two nuts to lock the T-bolt threads to achieve the fixation of the first connecting plate 64 and the spray terminal mounting column 63. When adjusting, loosen the two nuts and directly pull the first connecting plate 64 up and down. After the first connecting plate 64 reaches the required position, use the nuts to lock it again to achieve the fixation of the first connecting plate 64 and the spray terminal mounting column 63.

[0061] A second connecting plate 66 is also connected to the tail end of the spray dock 61. The second connecting plate 66 is an L-shaped plate. One side of the second connecting plate 66 is movably connected to the first connecting plate by the cooperation of bolts and nuts. When connected, the second connecting plate 66 and the first connecting plate 64 are provided with a through hole for the bolt to pass through. After the second connecting plate 66 is aligned with the through hole of the first connecting plate 64, the bolts are passed through the through holes on the second connecting plate 66 and the through holes on the first connecting plate 64 in turn, and then tightened with nuts, thereby achieving the fixation between the second connecting plate 66 and the first connecting plate 64. When adjusting, the nut is directly loosened, and then the second connecting plate 66 is rotated to achieve the adjustment of the angle of the spray dock 61. After the spray dock 61 is rotated to the required position, the nut is tightened to complete the fixation. The other side of the second connecting plate 66 is directly fixed to the tail end of the spray dock 61. The connection between the inkjet printer 6 and the inkjet terminal 61 adopts the cooperation between the inkjet terminal mounting column 63, the first connecting plate 64, and the second connecting plate 66, so that the inkjet terminal 61 can be adjusted up and down and at different angles to facilitate the cooperation between the inkjet terminal 61 and the workpiece.

[0062] The unloading unit includes an unloading tray and an unloading robot. There are several unloading trays, which are arranged in parallel beside the sorting platform and beside the loading and conveying assembly. A packing box or a packing box is placed above the unloading tray. The number of unloading trays is consistent with the number of stator specifications with different oil resistances. An unloading clamp is installed on the unloading robot. The loading robot and the unloading robot are the same robot, and the loading clamp and the unloading clamp are the same clamp. By distributing the unloading trays beside the loading and conveying assembly, the loading robot 3 and the unloading robot can be realized by using one robot, which reduces the number of robots and clamps required and reduces costs.

[0063] Each driving cylinder in this embodiment can be a hydraulic cylinder.

[0064] Working principle: First, the processed stator workpieces are placed one by one on the workpiece support plate 35 by manual or mechanical hands, and the loading and conveying motor 34 starts to work to convey the stator workpiece to the sorting platform 21. When the first stator workpiece is conveyed to the edge of the loading and conveying bracket 31, the loading and conveying motor 34 stops conveying, and the loading robot 3 starts to work, driving the loading claw to grab the first stator workpiece and place it in the first workpiece positioning seat on the sorting platform 21. Then, the loading and conveying motor 34 continues to convey until the second stator workpiece is conveyed to the edge of the loading and conveying bracket 31, and then stops conveying. While the loading and conveying motor 34 is conveying, the rotating motor 36 starts to work, and drives the sorting platform 21 to rotate 90° through the cam divider 25, so that the first workpiece positioning seat with the stator workpiece is placed moves to the oil resistance detection unit, and the second empty workpiece positioning seat moves to the side of the loading and conveying bracket 31, waiting to receive the second stator workpiece. Repeatedly, the automatic loading of stator workpieces is realized.

[0065] When the oil resistance detection is performed, the sorting platform 21 stops rotating, and the corresponding feeding and conveying motor 34 also stops conveying. Then, the second lifting cylinder 48 drives the first oil return tank 401 upward, thereby driving the workpiece top plate 412 and the centering shaft 42 to rise synchronously. Moreover, as the first oil return tank 401 moves upward, the centering shaft 42 will first contact the stator workpiece and pass through the center of the mounting through hole 11 in the middle of the stator workpiece, thereby realizing the centering and fixing of the stator workpiece, and lifting the workpiece locating seat upward for a certain distance, so that the workpiece locating seat is no longer supported on the sorting platform 21. At the same time, the workpiece top plate 412 will contact and approach the workpiece locating seat. While the second lifting cylinder 48 is working, the first lifting cylinder 44 will also move downward. The oil resistance detection pressure plate 41 is driven to move downward until the oil resistance detection pressure plate 41 is fixed on the stator workpiece, thereby achieving the fixation of the stator workpiece, and then the oil supply pump 404 starts to work, and the oil in the oil supply tank 49 is transported to the oil resistance detection pressure plate 41, and sprayed out from the oil outlet of the oil resistance detection pressure plate 41, and then passes through the oil hole 13 of the stator workpiece, thereby completing the detection of the oil resistance of the stator workpiece, and the detection result is fed back to the inkjet printer 6. At the same time, the oil passing through the oil hole 13 of the stator workpiece will flow into the first return oil tank 401, and return to the oil supply tank 49 through the first return oil pipe 405 for recycling. After the detection is completed, the first lifting cylinder 44 and the second lifting cylinder 48 move upward and downward respectively to reset.

[0066] After the first lifting cylinder 44 and the second lifting cylinder 48 are reset, the sorting platform 21 rotates 90° again, so that the first stator workpiece moves to the cleaning unit, the second stator workpiece moves to the oil resistance detection unit, and the third stator workpiece enters the sorting platform 21, and then the third lifting cylinder 53 drives the cleaning wind hood 51 downward. During the downward movement of the cleaning wind hood 51, the air compressor starts working at the same time to supply air, and uses air to blow the oil remaining on the inclined surface of the stator workpiece into the second return oil tank 402, and the oil in the second return oil tank 402 also flows back to the oil supply tank 49 through the second return oil pipe 411 for recycling. After cleaning is completed, the third lifting cylinder 53 is reset upward, and the detection work at the oil resistance detection unit is the same as the above steps, which will not be explained here.

[0067] When the third lifting cylinder 53 and the oil resistance detection unit are reset, the sorting platform 21 rotates 90° again, so that the first stator workpiece moves to the inkjet unit, the second stator workpiece moves to the cleaning unit, the third stator workpiece moves to the oil resistance detection unit, and the fourth stator workpiece enters the sorting platform 21. At this time, according to the detection result received from the oil resistance detection unit by the inkjet printer 6, the corresponding identification code is selected and printed on the surface of the first stator workpiece.

[0068] After the coding is completed, wait for the cleaning unit and the oil resistance detection unit to be processed and reset, then the sorting platform 21 rotates 90° again, so that the first stator workpiece moves to the unloading unit, and the unloading robot (loading robot 3) is used to place the first stator workpiece into the corresponding unloading pallet, and then the loading robot 3 grabs the fifth stator workpiece and places it in the empty workpiece positioning seat, and the cycle is repeated to complete the assembly line work.

[0069] The sorting system of the present invention utilizes the cooperation among the sorting platform, the loading unit, the oil resistance detection unit, the cleaning unit, the coding unit and the unloading unit, thereby realizing the automation of oil resistance detection, cleaning, coding and classification of the workpieces. It does not require manual operation and turnover, is very convenient, and improves work efficiency. Moreover, the entire sorting process is automated, thus avoiding the deviation phenomenon caused by the manual screening process.

Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
