Description

Technical Field

[0001] This invention relates to the field of clutch hub welded assembly testing technology, and in particular to a C1 clutch hub welded assembly air tightness testing machine. Background Technology

[0002] The C1 clutch hub welded assembly airtightness testing machine is a specialized testing equipment applied to the clutch hub welding processing production line. Its core function is to perform airtightness sealing performance testing on finished and semi-finished C1 clutch hub welded assemblies. As a core transmission component of the automotive clutch, the sealing performance of the welded joints of the C1 clutch hub directly determines the assembly quality and reliability of the clutch assembly. If defects such as minute pores, cracks, or incomplete welds exist at the welding location, it can lead to air leakage and oil seepage during use, directly affecting the transmission stability and service life of the automotive clutch. Therefore, after the C1 clutch hub is welded, an airtightness testing process is necessary to check for welding defects, eliminate unqualified parts, and ensure the pass rate of subsequent assembly and the safety of vehicle operation. This testing process is also an indispensable quality control link in the clutch hub welding processing production.

[0003] Currently, the airtightness testing of C1 clutch hub welded assemblies is generally carried out using traditional split-type testing equipment. There is no dedicated automated testing equipment adapted to assembly line production scenarios. In conventional batch production and processing scenarios, enterprises rely on manual operation to complete the entire airtightness testing process. Workers need to manually place the C1 clutch hub welded assembly to be tested at the testing station, manually connect the sealing test joint, start the testing equipment, and then manually remove the workpiece and classify the qualified and unqualified products after the test is completed. The entire testing process is highly dependent on manual operation. The equipment only has a single air pressure testing function and cannot achieve automated collaborative operation, and its ability to adapt to modern assembly line batch production is poor.

[0004] The traditional manual-assisted inspection mode makes the overall process of airtightness inspection of C1 clutch hub welded assemblies cumbersome and the process connection slow. It cannot achieve rapid loading and unloading of workpieces and continuous inspection, which greatly increases the inspection time of a single workpiece. This directly leads to low overall production and inspection efficiency of the entire welding production line. At the same time, the inspection method in which all the alignment, operation and result judgment are manually participated in is greatly affected by the differences in the operator's work experience, concentration and operation techniques. Manual docking of sealing joints is prone to alignment deviation and poor sealing. Manual judgment of inspection results is also prone to subjective errors, resulting in frequent missed inspections and false inspections. It is impossible to accurately and consistently control the airtightness quality of each C1 clutch hub welded assembly, resulting in unstable product inspection accuracy and low good product screening accuracy. It is difficult to meet the high-precision and high-efficiency quality inspection requirements of industrial mass production. Summary of the Invention

[0020] Example Please see Figures 1-6In this embodiment of the invention, a C1 clutch hub welding assembly air tightness testing machine includes a chassis 1, a testing chamber 2 fixedly installed on the top of the chassis 1, a feeding mechanism 3 provided on one side of the testing chamber 2, a discharging mechanism 4 provided on the other side of the testing chamber 2, two lifting and bearing mechanisms 7 fixedly connected in the middle of the testing chamber 2, a testing mechanism 6 fixedly installed on the top of the testing chamber 2, and a positioning and conveying mechanism 5 fixedly installed on the rear side of the testing chamber 2. The testing mechanism 6 includes a telescopic cylinder 61, a leak detector body 62, and a hydraulic cylinder 63. The telescopic cylinder 61 is fixedly connected to one side of the top inside the testing chamber 2, the leak detector body 62 is fixedly connected to the upper part inside the testing chamber 2, and the hydraulic cylinder 63 is fixedly connected to the other side of the top inside the testing chamber 2. A stamping detection head 64 is fixedly installed at the bottom output end of the hydraulic cylinder 63, and a leak detector side leak probe 65 is fixedly installed at the bottom output end of the telescopic cylinder 61. By setting up the overall machine body with matching conveying, bearing, handling, and testing structures working together, it is possible to complete C1 testing by relying on the loading mechanism 3 and the unloading mechanism 4. The automatic conveying and unloading of the clutch hub welding assembly, in conjunction with the lifting and bearing mechanism 7 inside the testing box 2, lifts the workpiece and fixes it at the testing station. Then, the positioning and transporting mechanism 5 completes the workpiece displacement adjustment, enabling the workpiece to form a complete automated flow process inside the equipment. There is no need for manual handling and placement of workpieces. During the testing operation, the telescopic cylinder 61 can drive the leak detector side leak probe 65 to complete the vertical displacement action, and in conjunction with the leak detector body 62, the air tightness test of the workpiece is carried out. At the same time, the hydraulic cylinder 63 can drive the stamping test head 64 to complete the vertical telescopic movement, and carry out the corresponding pressure test of the workpiece. The two testing processes are carried out synchronously and in coordination with the automated structure of the equipment, which can replace the traditional manual alignment test operation, reduce the number of manual operation steps, and avoid the test deviation caused by manual operation. The entire testing process continues to follow the rhythm of the automated workpiece flow, and can continuously complete the air tightness and pressure test of batch workpieces, effectively improving the overall workload of workpiece testing.

[0021] Please see Figures 3-6The feeding mechanism 3 includes a feeding box 31, which is fixedly installed on the side of the detection box 2 away from the unloading mechanism 4. The feeding box 31 is connected to the feeding port of the detection box 2. A feeding conveyor frame 32 is fixedly installed inside the feeding box 31. Feeding conveyor belts 33 are rotatably connected to both sides of the feeding conveyor frame 32. The unloading mechanism 4 includes a unloading box 41, which is fixedly connected to the side of the detection box 2 away from the feeding box 31. The inside of the unloading box 41 is connected to the unloading port of the feeding box 31. A unloading conveyor frame 42 is fixedly installed inside the unloading box 41. Unloading conveyor belts 43 are rotatably connected to both sides of the unloading conveyor frame 42. A barcode scanner is provided at the middle of one end of both the feeding conveyor frame 32 and the unloading conveyor frame 42 inside the detection box 2. By setting the feeding mechanism 3 and the unloading mechanism 4 to cooperate with each other, the feeding mechanism 3 can achieve the desired results during use. The interconnected box structure allows workpieces to smoothly enter and exit the inspection box 2. The continuous operation of the feeding conveyor belt 33 automatically feeds the workpieces to be inspected into the internal inspection area of ​​the equipment, replacing manual feeding and reducing manual intervention steps in the workpiece feeding process. At the same time, the operation of the unloading conveyor belt 43 automatically sends the inspected workpieces out, realizing automatic unloading of the inspected workpieces. The automated operation mode of loading and unloading can be matched with the rhythm of the internal inspection operation of the equipment, continuously supplying workpieces to the equipment inspection process and outputting finished workpieces. With the barcode scanners set at the ends of the two conveyor frames, information can be automatically recorded when the workpieces enter and exit the equipment, and the processing and inspection records of each workpiece can be retained throughout the process, eliminating the need for manual workpiece information registration and further simplifying the overall inspection operation process.

[0022] Please see Figures 5-6The lifting and carrying mechanism 7 includes a base frame 71 and reserved circular slots 72. The reserved circular slots 72 are located on both sides of the bottom of the testing chamber 2, directly below the stamping testing head 64 and the leak detector side leak probe 65. The base frame 71 is fixedly installed on both sides of the top inside the chassis 1. A lifting cylinder 73 is fixedly installed at the bottom of the base frame 71. The top of the lifting cylinder 73 passes through the reserved circular slots 72 and enters the testing chamber 2. A carrying fixture 74 is fixedly installed at the top output end of the lifting cylinder 73. A product placement rack 8 is placed on the front of the chassis 1, with a product placement slot 9 on its top. A maintenance double door 10 is hinged to the front of the chassis 1. An operation double door 11 is hinged to the front of the testing chamber 2. A PLC controller 12 is located at the upper front of the testing chamber 2, and a display screen 13 is located on the front of the PLC controller 12. Control buttons are located at the lower ends of both sides of the front of the testing chamber 2. The conveying mechanism 5 includes a moving component 51 and a clamping module 52. The moving component 51 is fixedly connected to the rear bottom of the inspection box 2. The clamping module 52 is linearly arranged at equal intervals and fixedly connected to the moving end of the moving component 51. Through the lifting and bearing mechanism 7 and the positioning and conveying mechanism 5, the entire system operates. During use, the lifting cylinder 73 passes through the reserved circular groove 72 to drive the lower fixture 74 to complete the height adjustment action, smoothly lifting the workpiece to the position below the corresponding inspection head. This allows the workpiece to be matched with the working position for airtightness testing and pressure testing, providing stable station support for workpiece inspection. The linearly arranged clamping modules 52 follow the moving component 51 to complete the overall displacement movement, enabling simultaneous transfer of multiple workpieces in a single movement. This achieves a synchronized operation process of workpiece loading, station switching, and finished product transfer. The equipment is equipped with a PLC. The controller, display screen 13 and control buttons can uniformly manage the overall operation program of the equipment, directly control the operating rhythm of each mechanism, and adapt to the needs of automated continuous operation. The maintenance double door 10 and operation double door 11 set in the chassis 1 and the detection box 2 respectively can carry out maintenance work on the internal structure when the equipment is stopped. The product placement rack 8 and product placement slot 9 set on the front of the chassis 1 can neatly store all the workpieces that have been tested.

[0023] Please see Figures 3-6The moving component 51 includes a mounting frame 511, which is fixedly installed on the rear bottom side of the detection box 2. A transverse linear module 512 is fixedly installed on the top of the mounting frame 511. A fixing plate 513 is fixedly installed on the moving end of the transverse linear module 512. A longitudinal drive cylinder 514 is fixedly installed on the top of the fixing plate 513. A lifting plate 515 is fixedly installed on the bottom output end of the longitudinal drive cylinder 514. Clamping modules 52 are linearly arranged at equal intervals and fixedly installed on the moving end of the lifting plate 515. The clamping modules 52 include a base 521. Both sides of 21 are fixedly installed with clamping electric cylinders 522. A clamping moving plate 523 is fixedly installed on the outer end of the clamping electric cylinders 522. A clamping block 524 is fixedly installed on the front side of the clamping moving plate 523. A clamping groove 525 is formed on the inner side of the clamping block 524. The top view of the clamping groove 525 is an isosceles trapezoidal concave shape. Anti-slip stripes 526 are evenly spaced on both sides of the clamping groove 525. By setting the moving component 51 to work in conjunction with the clamping module 52, the entire structure of the transverse linear module 512 can be supported by the mounting frame 511 during use. The moving end of the horizontal linear module 512 drives the fixed plate 513 to complete the horizontal displacement adjustment. Combined with the vertical drive cylinder 514, it drives the lifting plate 515 to perform vertical lifting motion, allowing flexible adjustment of the working position and height of the clamping module 52. This enables the completion of the entire process of workpiece picking, repositioning, and feeding. The clamping module 52 can rely on the clamping cylinders 522 on both sides of the base 521 to drive the clamping moving plate 523 to perform translational movement, which can drive the clamping block 524 to complete the opening and closing action, thereby completing the clamping and releasing operations on the workpiece. The isosceles trapezoidal clamping groove 525 on the inner side of 24 can conform to the outer contour of the workpiece. The anti-slip stripes 526 set inside the clamping groove 525 can increase the friction at the workpiece clamping contact position, so that the workpiece can remain stable throughout the entire transfer process and will not loosen or shift. The unified linkage operation mode of multiple clamping modules 52 can simultaneously complete the transfer process of workpieces at multiple workstations, making the overall workpiece flow operation of the equipment more continuous. It can continuously cooperate with the equipment inspection process to complete the automated cycle operation, which can effectively improve the inspection accuracy and inspection efficiency of this equipment.

[0024] The working principle of this invention is as follows: During application, when the equipment is in operation, the staff only needs to place the C1 clutch hub welding assembly to be inspected on the surface of the feeding conveyor belt 33. The feeding conveyor belt 33, relying on the feeding conveyor frame 32, runs continuously and can smoothly transport the workpiece to be inspected to the fixed material picking position inside the inspection box 2. The barcode scanner installed at one end of the feeding conveyor frame 32 will scan and record the information of the workpiece entering the workstation in real time. The overall operation and shutdown of the equipment and various operating parameters can be set and adjusted through the control buttons on the front of the inspection box 2 and the PLC controller 12. Various inspection data of the equipment operation will be displayed on the display screen 13 in real time. The double maintenance door 10 set in the chassis 1 and the double operation door 11 set in the inspection box 2 can allow the staff to carry out internal structural inspection and daily maintenance work when the equipment is stopped.

[0025] After the workpiece is conveyed to the material handling position inside the inspection box 2, the horizontal linear module 512 starts its horizontal movement, while the vertical drive cylinder 514 works in sync to complete the vertical extension and retraction, which can drive the entire lifting plate 515 and all clamping modules 52 to move as a whole. The vertical drive cylinder 514 can adjust the vertical working height according to the actual size of the workpiece to adapt to the material handling and clamping height requirements of different specifications of workpieces. After moving to the designated position, the clamping cylinder 522 starts running and drives the clamping moving plate 523 to move inward, and the clamping moving plate 523 drives the clamping plate to move closer in sync. The isosceles trapezoidal clamping groove 525 on the inner side of the clamping block 524, together with the anti-slip stripes 526 on the surface, fits against the outer wall of the workpiece to complete the clamping and fixing. It can stably clamp C1 clutch hub welding assemblies with different outer diameters. After the workpiece is completely fixed, the transverse linear module 512 moves in the opposite direction to reset, and accurately places the clamped workpiece to be tested on the top of the lower fixture 74 of the lifting bearing mechanism 7. The lifting electric cylinder 73 can adjust the vertical height of the lower fixture 74 according to the testing operation requirements, so as to match the working height of the testing mechanism 6 and ensure that the workpiece station placement position conforms to the testing operation standard.

[0026] The clamping modules 52 of this device are fixed to the bottom of the lifting plate 515 in a linearly arranged manner with equal spacing. During a single horizontal movement of the transverse linear module 512, all clamping modules 52 will move synchronously. Each clamping module 52 corresponds to an independent workstation and completes different processes synchronously. The first clamping module 52 will accurately grab the new workpiece to be tested from the feeding conveyor belt 33 and place the workpiece on the empty supporting fixture 74 at the bottom of the leak detector side leak probe 65, completing the loading and positioning of the new workpiece. The second clamping module 52 will... Simultaneously, the workpiece that was originally placed at the bottom of the leak probe 65 of the leak detector and has completed the airtightness test is transported as a whole and moved to the upper part of the supporting fixture 74 corresponding to the bottom of the stamping test head 64, completing the workpiece testing station switching operation. The last clamping module 52 will simultaneously grab the finished workpiece that has completed the pressure test at the bottom of the stamping test head 64 and directly transport the finished workpiece to the surface of the unloading conveyor belt 43. The entire set of displacement actions completes the three operations of loading, station switching and finished product unloading in one go, and each process is synchronized and parallel without interruption.

[0027] After the workpiece is positioned at its corresponding workstation, the detection structures at that workstation start working in sequence. The leak detector side leak probe 65 moves vertically downwards driven by the telescopic cylinder 61, and comes into contact with the workpiece welding position to complete the airtightness leak detection. The stamping detection head 64 moves vertically downwards driven by the hydraulic cylinder 63, and uses its own pressure sensor to perform pressure detection and compressive strength detection on the workpiece. After all the detection processes are completed, the unloading conveyor 42 drives the unloading conveyor belt 43 to continue running, conveying the finished workpieces placed on the surface of the conveyor belt outwards. The barcode scanner at the end of the unloading conveyor 42 will simultaneously record the unloading information of the finished workpieces. The staff can collect the conveyed and tested workpieces and place them in the product placement slot 9 at the top of the product placement rack 8. The equipment continuously cycles through the above synchronous repositioning operation process, and continuously completes the automated detection and processing of workpieces.

[0028] This technical solution achieves multi-station synchronous operation through multiple clamping modules 52 arranged at equal intervals. A single module movement can simultaneously complete all processes, including loading new workpieces, switching inspected workpieces to new workpieces, and unloading finished workpieces. This allows the equipment to operate continuously throughout the entire inspection process, eliminating workpiece idling and waiting times. It completely eliminates the need for manual step-by-step workpiece handling. The lifting electric cylinder 73 can adjust the working height of the supporting fixture 74 in real time, the longitudinal drive electric cylinder 514 can adjust the vertical height of the clamping operation, and the clamping electric cylinder 522 can adjust the clamping spacing of the clamping blocks 524. Multiple adjustments are possible. The interconnected structures are adaptable to clamping and inspection of C1 clutch hub welding assemblies of different specifications and sizes, thus broadening the equipment's applicability. The entire process of workpiece handling, positioning, inspection, and unloading is completed through a fully automated mechanical structure, completely replacing the traditional manual operation mode and eliminating operational deviations caused by manual operation. The multi-process synchronous parallel operation mode can make full use of the equipment's workstations, significantly improving the efficiency of batch workpiece inspection. The double-end scanning structure can completely retain workpiece inbound and outbound data, facilitating workpiece quality information traceability. The matching opening and closing door structure can simplify the daily inspection and maintenance process of the equipment.
