DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. The present application can be implemented without some of these specific details for those skilled in the art. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0019] The orientation words appearing in the following description are the directions shown in the drawings and do not limit the specific structure of the present application. In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection or integrally connected; it can be directly connected or indirectly connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0020] As shown in Figures 1 to 3 The turbocharger integrated assembly detection device includes a rack 1, a cam divider 3, a clamp spring feeding assembly 5, an impeller feeding assembly 4 and a sealing test assembly 6. The cam divider 3 is fixed on the table surface of the rack 1, and the output end thereof is fixedly connected with a turntable. The bottom of the rack 1 is provided with a drive motor 2, and the output end thereof is drivingly connected with the input end of the cam divider 3 through a synchronous belt. The cam divider 3 converts the continuous rotary motion of the drive motor 2 into the intermittent motion of the turntable, so that the turntable can rotate accurately according to the set angle and time interval.

[0021] The rotating disc is fixed with no less than four groups of lower sealing seats 11, which provide stable and unified positioning reference for turbocharger intermediates. The manipulator accurately places the intermediate to be assembled on the lower sealing seat 11, the cam divider drives the rotating disc to rotate clockwise intermittently, and the lower sealing seat 11 sequentially passes through the snap spring feeding assembly 5, the impeller feeding assembly 4, the sealing test assembly 6 and other stations, and completes the corresponding assembly and detection operation. The intermediate that has completed assembly and detection returns to the initial position of the rotating disc by the manipulator, and is taken down, forming a complete cycle.

[0022] As shown in Figure 3 , the snap spring feeding assembly 5 is composed of a press-fitting assembly 13 and a feeding assembly 14. The feeding assembly 14 is responsible for accurately feeding the snap spring from the storage position to the press-fitting position, and the press-fitting assembly 13 vertically presses the snap spring at the press-fitting position into the designated part of the turbocharger intermediate, and the two work together to realize the automatic feeding of the snap spring.

[0023] As shown in Figure 4 , the press-fitting assembly 13 includes a first stand 15, a top plate 17 and a guide cylinder 24. The first stand 15 is vertically fixed on the table surface of the rack 1, and the top plate 17 is horizontally installed on the top of the first stand 15 to provide a stable installation basis for other components. A second stand 22 is erected on one side of the top plate 17, and a first servo cylinder 21 is fixed on the top of the second stand 22. The output end of the first servo cylinder 21 is fixed with a press cylinder 23. The bottom of the press cylinder 23 is provided with a plurality of circumferentially distributed petals. The bottom of the petals is inlaid with a magnetic sheet that can attract the snap spring, preventing the snap spring from falling during the press-fitting process and ensuring the smooth progress of the press-fitting process.

[0024] As shown in Figure 6 and Figure 7 , the guide cylinder 24 is vertically slidingly fitted with the top plate 17, and the axis of the guide cylinder 24 is collinear with the axis of the press cylinder 23. The top of the guide cylinder 24 is provided with an integrated rectangular table plate 28. The upper end surface of the table plate 28 is provided with a blanking cavity 34, and the bottom of the blanking cavity 34 is provided with a guide cavity 33 penetrating through the guide cylinder 24. The guide cavity 33 is in a tapered structure with a large upper part and a small lower part, so as to guide the snap spring to the correct press-fitting position.

[0025] The bottom of the table plate 28 is fixed with a movable guide rod 32 penetrating through the top plate 17, and the top plate 17 is fixed with a guide sleeve 30 matched with the guide rod 32, forming a sliding guide pair to ensure that the guide cylinder 24 can only move vertically and eliminate lateral deviation. A spring is sleeved on the guide rod 32 and elastically abuts between the guide sleeve 30 and the table plate 28. During press-fitting, the spring can buffer the impact force of the press cylinder 23, avoiding damage to the snap spring or equipment caused by hard contact, and pushing the table plate 28 back to its original position after press-fitting, preparing for the next feeding.

[0026] The bottom of the platform 28 is fixed with a limiting rod 29, which is movably penetrated through the top plate 17, and the lower end of the limiting rod 29 is fixed with a tail seat 31, which is limited to abut against the lower end surface of the top plate 17, so as to limit the maximum reset height of the guide cylinder 24.

[0027] As shown in the drawings, the feeding assembly 14 comprises a material table 16 fixed on the top plate 17, one end of the material table 16 is in close contact with one end of the platform 28, so as to realize seamless connection of the clamp spring from conveying to pre-positioning before pressing. Figure 5

[0028] The upper end surface of the material table 16 is provided with a sliding groove, and a feeding plate 26 towards the pressing assembly 13 is slidably connected in the sliding groove. The end of the feeding plate 26 close to the pressing cylinder 23 is provided with a blanking hole 27, and the hole diameter of the blanking hole 27 is matched with the hole diameter of the blanking cavity 34. One side of the material table 16 is provided with a first sliding table air cylinder 18, and the output end of the first sliding table air cylinder 18 is fixedly connected with the feeding plate 26 through a connecting plate 25.

[0029] The material table 16 is fixed with a material cylinder 19, and the inside of the material cylinder 19 is provided with a pressing block 20. The material cylinder 19 realizes batch supply of the clamp spring through stacking storage, and the pressing block 20 provides continuous pressure to ensure the orderly discharge of the clamp spring. The feeding position of the blanking hole 27 corresponds to the discharge port of the material cylinder 19, and the discharging position of the blanking hole 27 corresponds to the upper end opening (blanking cavity 34) of the guide cylinder 24.

[0030] The bottommost clamp spring in the material cylinder 19 is pushed into the blanking hole 27 of the feeding plate 26 (i.e. the feeding position) under the joint action of the self-stacking pressure (the gravity of the upper clamp spring) and the continuous pushing force of the pressing block 20. The first sliding table air cylinder 18 is started, the feeding plate 26 is driven to move along the sliding groove of the material table 16 through the connecting plate 25, and finally the blanking hole 27 is stopped above the blanking cavity 34 (i.e. the discharging position). After the blanking hole 27 reaches the discharging position, the clamp spring loses the constraint and naturally falls into the blanking cavity 34 of the platform 28 under the action of gravity. Then the first sliding table air cylinder 18 drives the feeding plate 26 to reset, the blanking hole 27 is aligned with the discharge port of the material cylinder 19 again, and waits for the next feeding, forming a feeding cycle.

[0031] The first servo electric cylinder 21 is started, and the pressing cylinder 23 is pushed to vertically move downward. The petals at the bottom of the pressing cylinder 23 first contact the clamp spring in the blanking cavity 34, and the magnetic sheet at the bottom of the petals adsorbs the clamp spring through magnetic force, so as to ensure that the clamp spring will not fall off or be misaligned in the subsequent movement.

[0032] The pressing cylinder 23 continues to move downward, and the clamp spring is driven into the conical guide cavity 33 of the guide cylinder 24. The cavity wall of the guide cavity 33 generates radial extrusion force on the clamp spring, so that the clamp spring is gradually shrunk to the preset size.

[0033] ​At the same time, since the inner diameter of the guide cavity 33 is smaller than the maximum outer diameter of the clavus in the uncontracted state, the cavity wall of the guide cavity 33 synchronously generates a radial extrusion force on the circumferential clavus, so that the clavus is retracted inward, ensuring that the clavus always adheres to the clasp and maintaining the stability of magnetic adsorption.

[0034] During the downward movement of the compression cylinder 23, the friction force between the clavus and the cavity wall is greater than the pre-pressing force of the spring, forcing the guide cylinder 24 to move downward with the compression cylinder 23, so that the lower end of the guide cylinder 24 extends into the inner cavity of the intermediate body. When reaching the end of the stroke, the clasp is released from the radial constraint of the guide cavity 33, and by virtue of its elastic reset, the diameter increases and accurately clamps into the pre-set limiting groove of the intermediate body, completing the assembly.

[0035] After the assembly of the clasp is completed, an axial positioning and locking structure is formed on the sealing end cover inside the intermediate body, ensuring that the sealing end cover completely adheres to the sealing surface of the intermediate body, eliminating the gap caused by the offset of the sealing end cover, and facilitating the subsequent sealing test.

[0036] As shown in Figure 1 , Figure 2 and Figure 8 , one side of the rack 1 is provided with a plate chain conveyor 8, and the oven 7 is installed on the plate chain conveyor 8. The impeller and the impeller shaft adopt an interference fit, which is difficult to assemble at room temperature. The oven 7 continuously heats the impeller in conveying, uses the principle of thermal expansion and cold contraction to make the inner hole of the impeller expand, reduces the assembly resistance, and ensures that the impeller can be smoothly sleeved on the impeller shaft. After cooling, shrinkage forms a tight fit.

[0037] The conveying end of the plate chain conveyor 8 is opposite to the feeding position of the impeller feeding assembly 4, ensuring that the heated impeller can be timely grabbed by the impeller feeding assembly 4.

[0038] The impeller feeding assembly 4 includes a third stand 35 erected on the rack table, and a second slide cylinder 36 is fixed on one side of the third stand 35. The output end of the second slide cylinder 36 is fixed with a second cylinder 37, and the output end of the second cylinder 37 is fixed with a clamping jaw cylinder 38.

[0039] The table of the rack 1 is provided with a first cylinder 9 through a support frame, and the output end of the first cylinder 9 is fixed with a pressure head 10, which is opposite to the unloading position of the impeller feeding assembly 4. After the clamping jaw cylinder 38 preliminarily sleeves the impeller on the impeller shaft, the first cylinder 9 drives the pressure head 10 to apply a pre-set pressure downward, ensuring that the impeller is completely press-fitted in place and reaches the axial limiting position.

[0040] A displacement sensor 12 is arranged at the bottom center of the lower sealing seat 11. The axial load applied by the pressure head 10 is transmitted to the impeller shaft through the impeller, causing the impeller shaft to have a downward trend, i.e., an axial displacement amount. The displacement sensor 12 captures the axial displacement distance of the impeller shaft in real time, completes the displacement data collection, and can not only avoid workpiece damage (prevent the pressure head 10 from excessively descending to cause deformation of the impeller or the impeller shaft), but also eliminate the intermediate body with unqualified (abnormal displacement amount indicating that the limiting structure fails).

[0041] As shown in Figure 9 The sealing test assembly 6 includes a fourth stand 40 erected on the table top, and a second servo electric cylinder 41 is fixed to the top of the fourth stand 40. A connecting seat 42 is vertically and slidably connected to one side of the fourth stand 40 close to the turntable, and the upper end of the connecting seat 42 is fixedly connected to the output end of the second servo electric cylinder 41. The lower end of the connecting seat 42 is fixedly connected to an upper sealing seat 44 in the shape of a volute, and the inner walls of the upper sealing seat 44 and the lower sealing seat 11 are both provided with air pressure sensors. The lower end face of the upper sealing seat 44 and the upper end face of the lower sealing seat 11 are both provided with silica gel rings to enhance the air tightness.

[0042] The top of the upper sealing seat 44 is provided with a transparent observation window 43, and a vision sensor is mounted on the top of the upper sealing seat 44, with the detection end of the vision sensor facing the observation window 43 to monitor the change of the impeller gap. One side of the upper sealing seat 44 is provided with an air inlet 45, and the air inlet 45 is connected with a solenoid valve, and the input end of the solenoid valve is provided with a quick connector.

[0043] The second servo electric cylinder 41 is started to drive the upper sealing seat 44 to vertically descend, press the intermediate body of the turbocharger towards the lower sealing seat 11, and complete the film combination. The gas compression end of the intermediate body forms a closed chamber with the lower sealing seat 11, and the turbine end of the intermediate body forms a closed chamber with the upper sealing seat 44. During the test, the two groups of closed chambers are respectively filled with gas at a preset pressure. If the sealing performance of the intermediate body is qualified, the pressure will remain stable within the set pressure maintaining time; if there is leakage, the pressure will decrease over time, and the air pressure sensor can capture the pressure decay amount to quantitatively judge whether the sealing performance meets the standard.

[0044] After the sealing detection is completed, the impeller gap detection is performed. The second servo electric cylinder 41 drives the upper sealing seat 44 to rise to a preset position to complete the pressure relief. The solenoid valve is opened, and the compressed air is sent to the air inlet 45 through the air conveying pipe. The airflow blows towards the impeller along the flow channel in the upper sealing seat 44, and the airflow directly acts on the impeller to drive the impeller to rotate around the shaft. If there is a deviation in the installation position of the impeller shaft, the impeller will appear eccentric during the rotation process, causing the radial distance between the impeller and the upper sealing seat 44 to change regularly with the rotation period. The vision sensor captures the distance change data of the impeller in real time, and judges whether the installation deviation exists and the degree of the deviation through the data fluctuation.

[0045] In accordance with the present application as described above, the embodiments are not described in detail with reference to all of the possible modifications and alternatives. As is apparent to one of ordinary skill in the art, many modifications and changes can be made without departing from the spirit and scope of the application. The above description is intended to be illustrative, and not restrictive. Many embodiments of the application will be apparent to those of skill in the art upon reviewing the above description. The scope of the application should, therefore, be determined not with reference to the above description, but instead with reference to the appended claims, along with their full scope of equivalents.
