Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel hub manufacturing technology, and in particular to a wheel hub blank pre-inspection device. Background Technology

[0002] In the production of aluminum alloy wheels, the casting dimensional accuracy of the wheel blank directly affects the machining quality. Factors such as the riser height, end face quality, and concentricity of the blank determine whether the final machined product's dimensions and appearance meet quality requirements. For example, if the riser height of the wheel blank is out of tolerance or if aluminum chips or impurities are present and not removed in time, errors will occur during machining positioning, resulting in non-compliant dimensions after machining; non-compliant end faces of the wheel blank will lead to poor balance runout, which can result in scrap; poor concentricity can easily lead to incomplete rim machining and the appearance of black skin. In actual production, existing automated wheel production lines lack efficient pre-inspection devices for wheel blanks, making it impossible to accurately control the quality of wheel blanks entering the machining process. If defective blanks are not detected in time, their entry into the machining process will affect the yield and effective output of the machining process.

[0003] Therefore, developing a wheel hub blank pre-inspection device for practical production, and performing online pre-inspection of wheel hub blanks before machining, is an urgent problem to be solved. Utility Model Content

The detection structure includes a distance measuring unit corresponding to the riser end face of the wheel hub blank to be inspected, for measuring the height data of the riser end face of the blank to determine whether the riser height data meets the machining requirements.

[0006] Preferably, the ranging unit is connected to the base frame via a support arm, and the ranging unit is a laser rangefinder.

[0007] Preferably, the detection structure includes an end face detection part provided on the upper end face of the wheel hub blank, used to detect the circumferential runout of the end face of the blank, so as to determine whether the end face quality of the wheel hub blank meets the machining requirements.

[0009] Preferably, the detection structure includes a rim detection part corresponding to the inner rim of the wheel hub blank, used to detect the radial runout of the wheel hub blank, so as to determine whether the concentricity of the wheel hub blank meets the machining requirements.

[0010] Preferably, the mounting frame is further provided with a purging structure corresponding to the wheel hub blank. The purging structure includes a blower pipe facing the wheel hub blank, and a compressed air source is connected to the blower pipe to supply high-pressure air to the blower pipe.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention enables pre-inspection of wheel hub blanks entering the machining process, allowing for timely identification of defective blanks and preventing low yield rates, wasted capacity, and reduced production costs caused by machining defective blanks. Furthermore, pre-inspection of wheel hub blanks allows for timely quality traceability of defective blanks, guiding the identification of potential quality issues and curbing the mass production of defective wheel hub blanks.

[0017] 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.

[0018] like Figure 1-2As shown, a wheel hub blank pre-inspection device includes a frame 10 as a support structure. A central chuck 11 for fixing the wheel hub blank is rotatably connected to the frame 10. The frame 10 also has a detection structure for pre-inspecting the wheel hub blank. In use, the wheel hub blank to be inspected is mounted on the central chuck 11 through a central shaft hole. The detection structure performs pre-inspection on the wheel hub. Wheel hub blanks that pass the pre-inspection are allowed to enter the machining process for subsequent processing. Products that fail the pre-inspection enter a recycling roller conveyor for rework or scrapping. This embodiment achieves pre-inspection of wheel hub blanks entering the machining process, enabling timely identification of defective blanks and avoiding the problems of low yield, wasted capacity, and production costs caused by machining defective blanks. Simultaneously, pre-inspection of wheel hub blanks allows for timely quality traceability of defective blanks, guiding the investigation of potential quality problems and curbing the mass production of defective wheel hub blanks.

[0019] Preferably, the detection structure includes a ranging unit 31 corresponding to the riser end face of the wheel hub blank to be detected, used to measure the height data of the riser end face of the blank to determine whether the riser height data meets the machining requirements. The ranging unit 31 is connected to the base frame 10 through the support arm 12, and the ranging unit 31 can be a laser rangefinder.

[0020] Preferably, the detection structure includes an end face detection part 32 corresponding to the upper end face of the wheel hub blank, used to detect the circumferential runout of the blank end face to determine whether the end face quality of the wheel hub blank meets the machining requirements. The end face detection part 32 can be a dial indicator, which is connected to the base 10 via a bracket 13.

[0021] Preferably, the detection structure includes a rim detection section 33 corresponding to the inner rim of the wheel hub blank, used to detect the radial runout of the wheel hub blank to determine whether the concentricity of the wheel hub blank meets the machining requirements. The rim detection section 33 can be a dial indicator.

[0022] Preferably, the mounting frame 10 is also provided with a blowing structure 40 corresponding to the wheel hub blank, which is used to blow away aluminum chips, water droplets and impurities on the surface of the wheel hub blank, so as to eliminate the influence of residual impurities on the blank surface on the test results and improve the test accuracy; at the same time, it solves the problem that the machining compensation parameters are affected by the interference of aluminum chips and impurities on the blank surface during the machining positioning process, resulting in unqualified dimensions after machining.

[0023] The blowing structure 40 includes a blowing pipe 41 facing the wheel hub blank. A compressed air source is connected to the blowing pipe 41 to supply high-pressure air to the blowing pipe 41, which powerfully blows away the aluminum chips and impurities remaining on the surface of the wheel hub blank.

[0024] During testing, the wheel hub blank to be tested is loaded into the central chuck 11, the wheel hub blank is rotated, and the blowing structure 40 is activated to perform high-pressure blowing on the surface of the blank to remove aluminum chips, water droplets, and impurities from the surface of the blank. After the blowing is completed, the distance measuring unit 31 performs height detection on the end face of the blank riser. The end face detection unit 32 and the rim detection unit 33 respectively abut against the end face of the blank in the rotating state and the inner rim to simultaneously complete the end face quality and concentricity detection.
