Description

Technical Field

[0001] This invention relates to the field of flywheel housing detection and control technology, and in particular to a lifting and separation assembly for optical detection of flywheel housings. Background Technology

[0002] The flywheel housing is a core component of the engine, primarily used to enclose the flywheel, connect the engine and the transmission, and play a crucial role in load-bearing protection, vibration damping, noise reduction, and transmission positioning. Its machining accuracy, appearance integrity, and the pass rate of assembly dimensions directly determine the operational stability, sealing performance, and service life of the engine's transmission system. Therefore, after the flywheel housing is manufactured, it is essential to conduct a comprehensive inspection of its parameters, appearance defects, and installation accuracy using specialized testing equipment. Defective products must be eliminated to ensure the quality of subsequent assembly and the safe operation of the equipment.

[0003] Currently, existing flywheel housing inspection equipment in the industry has a simple structural design and significant technical deficiencies in its inspection mode. Existing equipment only supports fixed inspection station operations and can only inspect flywheel housings that are stationary at a fixed inspection position. It cannot adapt to dynamic inspection of flywheel housings in motion on a production line. For flywheel housings continuously conveyed on the production line, the equipment cannot automatically adapt to the moving conditions to complete the inspection adjustment. The entire process requires manual adjustment of the equipment position, inspection angle, and inspection parameters by operators to complete a series of operations such as alignment, inspection, and resetting.

[0004] This manual inspection method is not only cumbersome and labor-intensive, significantly increasing labor costs and resulting in time-consuming, labor-intensive, and inefficient operations, but also suffers from inaccurate adjustments and large operational errors, leading to poor consistency and equipment stability. Furthermore, manual intervention is prone to missed or false detections, making it difficult to guarantee the accuracy and standardization of batch flywheel housing inspections. It fails to meet the demands of modern production lines for efficient, precise, and automated production inspections, severely hindering the improvement of quality and efficiency in the large-scale production of flywheel housings. Therefore, there is an urgent need to develop an automated inspection and control device and method suitable for flywheel housings in motion. Summary of the Invention

[0005] The technical problem this invention aims to solve is that existing flywheel housing inspection equipment only supports fixed inspection station operations and cannot adapt to dynamic inspection operations of flywheel housings in the moving state of the production line. It requires staff to manually adjust the equipment position, inspection angle and inspection parameters, resulting in cumbersome operation procedures, high work intensity, low inspection accuracy, poor consistency and operational stability, and difficulty in meeting the needs of efficient, accurate and automated inspection of the production line.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a lifting and separating assembly for optical inspection of flywheel housing, including a horizontal frame, an electrically controlled synchronous feeding roller group and an optical inspection head assembly mounted on the horizontal frame. The electrically controlled synchronous feeding roller group includes several feeding rollers movably mounted inside the horizontal frame, an external transmission box fixed on the outer side of the horizontal frame, and a synchronous transmission mechanism mounted inside the external transmission box. An electrically controlled lifting assembly is movably assembled inside the horizontal frame, and a central crossbeam tilting assembly for mounting the optical inspection head assembly is installed inside the horizontal frame.

[0007] Furthermore, lateral mounting through holes for mounting the feed rollers are symmetrically provided on both side plates of the horizontal frame. The feed rollers are movably mounted to the horizontal frame through the lateral mounting through holes via mounting shafts at both ends.

[0008] Furthermore, the synchronous transmission mechanism includes a main drive gear installed inside an external transmission box, a driven gear axially fixed on a shaft mounted at one end of the feed roller, and a transmission chain misaligned between the main drive gear and the driven gear and between adjacent driven gears.

[0009] Furthermore, the electrically controlled lifting assembly includes an electrically controlled lift fixed to the inner wall of the horizontal frame, a bottom lifting beam controlled by the electrically controlled lift, an electrically controlled horizontal guide rail installed on the bottom lifting beam, a sliding mounting seat slidably installed on the electrically controlled horizontal guide rail, a horizontal support rod for controlling the sliding mounting seat, a longitudinal extrusion column fixed to the upper end of the sliding mounting seat, and an electrically controlled adjusting wheel movably installed on the side wall of the longitudinal extrusion column.

[0010] Furthermore, the top of the longitudinally placed extrusion column is provided with a top transmission blind hole, and a top ball bearing is installed inside the top transmission blind hole.

[0011] Furthermore, the electrically controlled transverse guide rail includes a horizontal guide beam movably mounted on the bottom lifting beam and a horizontal adjustment support rod for adjusting the horizontal guide beam.

[0012] Furthermore, the central crossbeam flipping assembly includes an internal crossbeam fixed in the middle of the horizontal frame, a translation adjustment seat slidably installed on the outside of the internal crossbeam, a bottom translation support rod for controlling the translation adjustment seat, a flipping assembly frame hinged to the middle of the upper surface of the translation adjustment seat, and a central control support rod for controlling the flipping assembly frame. The optical detection head assembly is fixedly installed on the flipping assembly frame.

[0013] Furthermore, the optical detection head assembly includes a fixed mounting base fixed inside the flip assembly frame and a plurality of optical scanning probes mounted on the fixed mounting base.

[0014] Furthermore, LED fill lights are fixed on both sides of the optical scanning probe on the outer side of the fixed mounting base.

[0015] Furthermore, a side-mounted supplementary light is installed on the side wall of the longitudinally placed extrusion column.

[0016] The beneficial effects of this invention are as follows: By using an electrically controlled synchronous conveying roller assembly in conjunction with an electrically controlled lifting component, the flywheel housing in motion on the production line is automatically lifted and separated from the conveyor line, solving the technical bottleneck that existing equipment cannot adapt to moving inspection operations. It eliminates the need for manual adjustment of equipment position and inspection parameters, significantly reducing operational complexity and workload. Through the coordinated adjustment of the central crossbeam tilting assembly and the translation adjustment seat, multi-angle full-coverage optical scanning of each inspection surface of the flywheel housing is achieved, overcoming the defects of large accuracy deviations and poor inspection consistency caused by manual adjustment. Combined with stable illumination from the optical scanning probe and supplementary lighting, it effectively reduces missed and false detections, ensuring the standardization requirements of large-scale batch inspection.

[0023] The following is in conjunction with the appendix Figures 1 to 3 The technical solution of the present invention will be described in detail below.

[0024] like Figures 1 to 4 As shown, a lifting and separating assembly for optical inspection of flywheel housings according to the present invention includes a horizontal frame 100, an electrically controlled synchronous conveying roller assembly, an electrically controlled lifting assembly 200, a centrally located crossbeam tilting assembly 300, and an optical inspection head assembly 400. The horizontal frame 100 adopts a cuboid frame structure welded or cast from steel profiles. Multiple lateral mounting through holes 120 are symmetrically opened on both side plates of the frame along the length direction. Multiple conveying rollers 110 are movably assembled with the side plates of the frame through the lateral mounting through holes 120 via mounting shafts at both ends, and are arranged parallel to each other along the length direction of the frame to form a conveying channel. An external transmission box 130 is fixedly installed on the outer side of the horizontal frame 100. A synchronous transmission mechanism is installed inside, including a main drive gear 140, multiple driven gears 141 and a transmission chain 142. The driven gears 141 are axially fixed on the mounting shaft at one end of the corresponding feed roller 110. The transmission chain 142 is wound between the main drive gear 140 and each driven gear 141 as well as between adjacent driven gears 141, so as to realize the synchronous rotation drive of multiple rollers.

[0025] The electrically controlled lifting assembly 200 includes an electrically controlled lifting machine 210 fixed to the inner wall of the horizontal frame 100. The telescopic end of the electrically controlled lifting machine 210 is connected to a bottom lifting beam 220. An electrically controlled horizontal guide rail 230 is installed on the bottom lifting beam 220. The electrically controlled horizontal guide rail 230 consists of a horizontal guide beam 231 and a horizontal adjustment support rod 232. A sliding mounting seat 240 is slidably mounted on the horizontal guide beam 231, and its horizontal sliding position is controlled by the horizontal support rod 241. A longitudinal extrusion column 250 is fixedly connected to the upper end of the sliding mounting seat 240. A top transmission blind hole 251 is opened at the top of the longitudinal extrusion column 250, and a top ball bearing 252 is installed in the hole. An electrically controlled adjusting wheel 260 is movably mounted on the side wall of the longitudinal extrusion column 250, and a side-mounted supplementary light 270 is mounted on the side wall of the longitudinal extrusion column 250.

[0026] The central crossbeam tilting assembly 300 includes an internal crossbeam 310 fixed in the middle of the horizontal frame 100, a translation adjustment seat 320 slidably mounted on the outside of the internal crossbeam 310, a bottom translation support rod 321 for controlling the translation adjustment seat 320, a tilting assembly frame 330 hinged to the middle of the upper surface of the translation adjustment seat 320, and a central adjustment support rod 331 for controlling the tilting assembly frame 330. The optical detection head assembly 400 is fixedly mounted on the tilting assembly frame 330, including a fixed mounting base 410 and several optical scanning probes 420 mounted on the fixed mounting base 410. LED supplementary lights 430 are fixed on both sides of the optical scanning probes 420 on the outside of the fixed mounting base 410.

[0027] During operation, the flywheel housing is placed upside down on the electrically controlled synchronous conveying roller assembly with its opening facing downwards. It is conveyed to the set detection position by the synchronously rotating conveying roller 110 and then stops. The electrically controlled lifting platform 210 drives the bottom lifting beam 220 to move upwards, causing the sliding mounting base 240 and the longitudinal extrusion column 250 to pass upwards through the gap between adjacent conveying rollers 110, lifting the flywheel housing on the conveying roller 110 upwards and disengaging it from the conveying channel of the electrically controlled synchronous conveying roller assembly. Subsequently, the horizontal support rod 241 drives the sliding mounting base 240 to move outwards along the horizontal guide beam 231, causing the longitudinal extrusion column 250 to move outwards, so that the electrically controlled adjusting wheel 260 on the side wall of the longitudinal extrusion column 250 presses against the inner wall of the flywheel housing, confining the flywheel housing at the detection position. The bottom-mounted translational support rod 321 drives the translational adjustment seat 320 to translate along the built-in crossbeam 310. This, in conjunction with the centrally located adjustment support rod 331, adjusts the tilting angle of the flip assembly frame 330, moving the optical detection head assembly 400 above the center of the flywheel housing opening. The optical scanning probe 420 then faces downwards, aligning with the inner cavity of the flywheel housing, and begins optical scanning of the longitudinal inner wall of the flywheel housing. During scanning, the electrically controlled adjustment wheel 260 can drive the flywheel housing to rotate slightly around the axis of the longitudinal extrusion column 250, ensuring that the optical scanning probe 420 covers the entire circumferential range of the inner wall of the flywheel housing, avoiding scanning blind spots. When the optical detection head assembly 400 is in a horizontal state, the optical scanning probe 420 scans the top surface of the flywheel housing; when the centrally located adjustment support rod 331 drives the flip assembly frame 330 to a longitudinal position, the optical scanning probe 420 scans the inner wall of the flywheel housing. The side-mounted fill light 270 and the LED fill light 430 provide stable multi-angle illumination during scanning, ensuring the clarity of image acquisition by the optical scanning probe 420 at each scanning angle.
