Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a wheel hub hole position detection device. Background Art

[0002] After the aluminum alloy wheel hub blank is cast, the center hole position needs to be rough-machined through drilling or punching processes to facilitate subsequent turning processing. However, in actual production, since the wheel hub blank has not been fine-machined, a certain positioning deviation is likely to occur during clamping, resulting in a certain hole position deviation during the drilling or punching operation. Wheel hub blanks with hole position deviations exceeding the allowable range have a greater risk of collision during the subsequent turning process, that is, the turning tool is prone to collide with the center hole during lathe feeding, affecting normal production. Therefore, before the wheel hub blank enters the turning process, it is very necessary to identify and isolate the wheel hub blanks with hole position deviations exceeding the allowable range in advance. However, the current production site lacks a convenient detection device for the center hole position of the wheel hub blank.

[0003] Based on this, a wheel hub hole position detection device and a wheel hub punching detection device are designed to detect the center hole position of the wheel hub blank before turning. The blanks with hole position deviation exceeding the allowable range are picked out in time and processed separately or scrapped to prevent collisions from causing damage to the machine tool and affecting production. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1-2 As shown, a wheel hub hole position detection device comprises a support frame 1, the support frame 1 comprises a center seat 11 arranged corresponding to the center hole of the wheel hub, the center seat 11 is provided with a support arm 12 along the circumferential direction, and a positioning block 13 is arranged on the support arm 12 corresponding to the outer edge of the wheel hub, which is used to position the support frame 1 on the wheel hub. The support frame 1 is provided with a detection head 2 for detecting the hole position of the center hole of the wheel hub, the detection head 2 is axially slidably connected to the center seat 11, and the diameter of the detection head 2 is set corresponding to the aperture of the center hole of the wheel hub.

[0022] During the inspection, the support frame 1 is set up on the wheel hub to be inspected, and the positioning block 13 on the support arm 12 is fixed on the outer edge of the wheel hub to be inspected, so as to complete the positioning and setting of the support frame 1. At this time, the center seat 11 is just above the center hole of the standard wheel hub. If the detection head 2 can smoothly penetrate the center hole of the wheel hub to be inspected, it means that the center hole position of the inspected wheel hub meets the requirements and can enter the turning process; on the contrary, if the detection head 2 fails to penetrate the center hole of the wheel hub to be inspected, it means that the hole position deviation of the center hole of the inspected wheel hub exceeds the allowable range and cannot directly enter the turning process. This realizes the rapid detection of the hole position deviation of the wheel hub blank, effectively prevents the wheel hub with serious deviation from entering the turning process, avoids the risk of collision, and ensures the continuous stability of the production process.

[0023] As a preferred embodiment, a guide hole 111 is opened on the center seat 11, and a guide column 21 is connected to the tail end of the detection head 2. The guide column 21 is axially slidably matched with the guide hole 111. The guide column 21 can be extended and retracted under the guiding action of the guide hole 111 to realize the detection of the center hole of the wheel hub.

[0024] Furthermore, a stopper 22 is provided on the guide column 21 corresponding to the guide hole 111, which is used for the telescopic limit of the detection head 2. The diameter of the stopper 22 is larger than the aperture of the guide hole 111 to prevent the detection head 2 from being separated from the center seat 11. Furthermore, a detection stamp 23 is provided at the bottom of the stopper 22, so as to leave a detection mark on the wheel hub that has passed the inspection. During the inspection, the guide column 21 moves downward. If the detection head 2 successfully penetrates the center hole of the wheel hub, the detection stamp 23 provided at the bottom of the stopper 22 will contact the surface of the wheel hub and produce a detection mark, indicating that the hole position of the center hole of the inspected wheel hub is qualified; if the detection head 2 fails to penetrate the center hole of the wheel hub smoothly, the detection stamp 23 cannot contact the surface of the wheel hub, and the surface of the inspected wheel hub will not leave a detection mark, so that the subsequent turning processing operators can distinguish and confirm. The detection stamp 23 can be set as the code of the inspection personnel or a simple qualified mark to facilitate product traceability.

[0025] Furthermore, a guide sleeve 112 is provided on the center seat 11 corresponding to the guide column 21 to further improve the motion precision of the detection head 2 and the detection accuracy. The outer diameter of the guide column 21 is slidably matched with the inner diameter of the guide sleeve 112, so that the stopper 22 fits the lower end surface of the center seat 11.

[0026] Furthermore, a reset spring 113 is provided corresponding to the detection head 2, which is used for the automatic return of the detection head 2, so that the structure is compact and stable. Specifically, the reset spring 113 is sleeved on the guide column 21, one end of the reset spring 113 is fixed to the top of the guide column 21, and the other end is supported on the guide hole 111 of the center seat 11 to provide elastic force to lift the detection head 2. During the inspection, the inspection personnel push the guide column 21 to overcome the elastic force of the reset spring 113, so that the detection head 2 moves downward. If the detection head 2 can smoothly penetrate into the center hole of the wheel hub, it indicates that the hole position of the center hole of the wheel hub is qualified; if the detection head 2 cannot smoothly penetrate into the center hole of the wheel hub, it indicates that the hole position of the center hole of the wheel hub is unqualified. After the inspection is completed, the inspection personnel release the guide column 21, and the reset spring 113 will lift and reset the detection head 2.

[0027] In a further embodiment, the position of the positioning block 13 on the support arm 12 is adjustable to adapt to the center hole position detection of wheels of different specifications and sizes, thereby improving the applicability of the utility model. Specifically, a slide groove 121 is provided on the support arm 12 along the length direction, and the positioning block 13 is slidably connected to the slide groove 121. By adjusting the position of the positioning block 13 on the support arm 12, the positioning and fixing of wheels of different specifications and sizes can be achieved, so that the utility model has a certain degree of versatility. Preferably, a scale ruler 122 is provided on the slide groove 121, which is used as a dimensional reference for the position adjustment position of the positioning block 13, so as to facilitate the operator to quickly adjust and ensure the adjustment accuracy.

[0028] Furthermore, the detection head 2 is detachably connected to the guide column 21. When detecting wheel hubs with different center hole diameters, the detection of wheel hubs with different center hole diameters can be quickly implemented by disassembling and replacing the detection head 2 with different diameters, further improving applicability.

[0029] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, any deformation made should be regarded as belonging to the protection of the present invention.
