Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel hub manufacturing technology, and in particular to an online detection and correction device for the roundness of wheel hub blanks. Background Technology

[0002] After aluminum alloy wheel blanks are cast, deviations in the process or execution may cause the roundness of the blanks to exceed tolerances. During machining, these blanks are prone to defects such as black rind skin, which cannot be properly machined. Therefore, wheel blanks need to undergo roundness inspection before machining. Products with roundness exceeding tolerances must be individually corrected or scrapped.

[0003] Traditional roundness inspection methods require operators to transport wheel hubs to specialized equipment for testing. After inspection, wheel hub blanks with out-of-roundness tolerances are corrected or scrapped, while those with acceptable roundness are released to the machining process. Since wheel hub blanks are generally heavy, manual handling is difficult, increasing the labor intensity of on-site workers and affecting work efficiency. Furthermore, manual sorting of wheel hub blanks increases the risk of misdirected defective products.

[0004] Therefore, developing an online detection and correction device for the roundness of wheel hub blanks for practical production is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems by providing an online detection and correction device for the roundness of wheel hub blanks. The technical solution adopted by this utility model is as follows:

[0006] An online detection and correction device for the roundness of wheel hub blanks includes a conveyor roller conveyor for conveying the wheel hub blanks to be inspected, a wheel hub support for positioning and supporting the wheel hub blanks to be inspected is provided on the conveyor roller conveyor, a measuring head is provided corresponding to the wheel hub blanks to be inspected, and a correction device is provided corresponding to the conveyor roller conveyor for correcting wheel hubs with out-of-roundness tolerances. The correction device includes a top pressure block provided corresponding to the wheel hub blanks, and the top pressure block is connected to a telescopic hydraulic cylinder to obtain the power to push out and press the wheel hub.

[0007] Preferably, the wheel hub support includes a support plate for supporting the wheel hub blank to be tested, a central expansion sleeve for mounting the center hole of the wheel hub is provided on the support plate, and a lifting rod is connected to the bottom of the support plate.

[0008] Preferably, the conveyor roller conveyor includes a qualified product roller conveyor for conveying roundness-compliant wheel hubs, and a scrap product roller conveyor for conveying roundness-incompatible wheel hubs.

[0009] Preferably, the waste roller conveyor and the qualified roller conveyor are arranged in layers, with the waste roller conveyor located below the qualified roller conveyor. A diversion roller conveyor is also provided on the conveyor roller conveyor. The diversion roller conveyor can be connected to the qualified roller conveyor and the waste roller conveyor respectively through lifting and lowering actions. The lifting and lowering actions of the diversion roller conveyor are achieved by lifting cylinders.

[0010] Preferably, the top pressure block is provided with an arc-shaped top pressure surface, and the curvature of the arc-shaped top pressure surface is set to correspond to the rim curvature of the wheel hub blank.

[0011] Preferably, the telescopic cylinder is connected to a hydraulic station to obtain the oil pressure for the telescopic cylinder's telescopic movement.

[0012] The beneficial effects of this utility model are as follows: During the use of this utility model, the wheel hub blank to be inspected can be transported to the inspection station for online inspection via the conveyor roller conveyor. This improves upon the traditional wheel hub blank roundness inspection process, which requires manual handling of the wheel hub blank to the inspection machine for inspection, reducing the labor intensity of operators and improving the inspection efficiency of wheel hub blank roundness. The setting of the correction device 40 realizes the online correction of wheel hubs with out-of-roundness tolerance, simplifies the process flow, and further improves the work efficiency. The setting of the layered conveyor roller conveyor realizes the online diversion of wheel hub blanks, reducing the risk of abnormal products being mis-transferred. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-4 As shown, an online detection and correction device for the roundness of wheel hub blanks includes a conveyor roller conveyor 10 for conveying the wheel hub blank to be inspected. A wheel hub support 20 is installed on the conveyor roller conveyor 10 for positioning and supporting the wheel hub blank. A measuring instrument 30 is also provided corresponding to the wheel hub blank. A correction device 40 is provided corresponding to the conveyor roller conveyor 10 for correcting wheel hubs with out-of-roundness tolerances. The correction device 40 includes a top pressure block 41 corresponding to the wheel hub blank, and the top pressure block 41 is connected to a telescopic hydraulic cylinder 42 to obtain the power to push out and press the wheel hub.

[0021] In use, the conveyor roller 10 transports the wheel hub blank to be inspected to the inspection position. The wheel hub support 20 positions and supports the wheel hub. The measuring head 30 contacts the rim of the wheel hub blank to detect the roundness of the wheel hub in real time. When the wheel hub blank is detected to be out of tolerance at a distance, the wheel hub is rotated to align the positive deviation direction of the roundness with the correction device 40. At this time, the telescopic cylinder 42 pushes out, driving the pressure block 41 to press against the positive deviation part of the wheel hub blank and apply pressure, thereby correcting the roundness of the wheel hub blank. After the correction is completed, the telescopic cylinder 42 returns, and the wheel hub is inspected for roundness again until the roundness is qualified for release or scrapping.

[0022] In this embodiment, the wheel hub blank to be inspected can be conveyed to the inspection station via the transfer roller conveyor 10 for online inspection. This improves upon the traditional wheel hub blank roundness inspection process, which requires manual handling of the wheel hub blank to the inspection machine, reducing the labor intensity of operators and improving inspection efficiency. The setting of the correction device 40 enables online correction of wheel hubs with out-of-roundness tolerances, simplifies the process flow, and further improves operational efficiency.

[0023] As a preferred embodiment, such as Figure 2-4 As shown, the wheel hub support 20 includes a support plate 21 for supporting the wheel hub blank to be inspected. A central expansion sleeve 22 is provided on the support plate 21 to hold the center hole of the wheel hub. A lifting rod 23 is connected to the bottom of the support plate 21. In use, the lifting rod 23 retracts, causing the support plate 21 to descend below the conveyor roller 10, allowing the wheel hub blank to be inspected to be smoothly transported to the inspection position via the conveyor roller 10. After the wheel hub blank is in place, the lifting rod 23 lifts the support plate 21 to rise and support the flange end face of the wheel hub blank, causing the wheel hub blank to detach from the conveyor roller 10 and tightening the central expansion sleeve 22 in the center hole of the wheel hub blank, completing the positioning and support of the wheel hub blank. After inspection, the lifting rod 23 retracts to its original position, releasing the wheel hub blank onto the conveyor roller 10.

[0024] Preferably, such as Figure 1-2 As shown, the conveyor roller conveyor 10 includes a qualified product roller conveyor 11 for conveying roundness-compliant hubs, and a scrap product roller conveyor 12 for conveying non-roundness-compliant hubs. After inspection, roundness-compliant hubs are conveyed to the machining process via the qualified product roller conveyor 11, while non-roundness-compliant hubs are conveyed to the scrap processing process via the scrap product roller conveyor 12.

[0025] Preferably, the waste roller conveyor 12 and the qualified product roller conveyor 11 are arranged in layers, with the waste roller conveyor 12 located below the qualified product roller conveyor 11. A diversion roller conveyor 13 is also provided on the conveyor roller conveyor 10, which can be connected to the qualified product roller conveyor 11 and the waste roller conveyor 12 via lifting and lowering actions. After inspection, roundness-compliant hubs are conveyed to the qualified product roller conveyor 11 via the rising diversion roller conveyor 13; roundness-deficient hubs are conveyed to the waste roller conveyor 12 via the descending diversion roller conveyor 13. Preferably, the diversion roller conveyor 13 is lifted and lowered by a lifting cylinder 14.

[0026] Preferably, such as Figure 4 As shown, the top pressure block 41 is provided with an arc-shaped top pressure surface 43. The arc of the arc-shaped top pressure surface 43 is set to correspond to the rim arc of the wheel hub blank so that the rim of the wheel hub blank is pressed evenly.

[0027] Preferably, the telescopic cylinder 42 is connected to the hydraulic station 44 to obtain the oil pressure for the telescopic cylinder 42 to extend and retract.

[0028] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
