Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile wheel hub measurement, and specifically relates to a calipers truck aluminum alloy wheel hub heat treatment roundness gauge. BACKGROUND

[0002] The wheel hub of truck, bus and other heavy vehicles is collectively referred to as calipers truck wheel hub, and the aluminum alloy integral casting type (including pure casting integral type and integral casting spinning type) is an important manufacturing method thereof, and the middle section and outer section of the wheel rim are the positions that are prone to casting deformation or spinning deformation. This manufacturing method needs a heat treatment process for improving the material performance of the calipers truck wheel hub, and the heat treatment process is divided into three sub-processes: solid solution, quenching and aging. During the solid solution and quenching process, certain deformation is caused by heating deformation and rapid quenching and cutting, so after the solid solution and quenching, the calipers truck wheel hub needs to go through the processes of flatness correction, front distance correction and roundness correction.

[0003] At present, the casting spinning process of the calipers truck aluminum alloy wheel hub is an important manufacturing process, and the key spinning position thereof is the wheel rim. The performance improvement feature thereof is that the performance improvement of the surface layer of the spinning surface is stronger, and gradually decreases towards the middle of the wheel rim wall thickness, so the deformation amount of the wheel rim position is reduced, and then the machining of the wheel rim can be completed with less machining amount, which will make the performance of the spinning wheel rim more optimal. Therefore, the flatness, front distance and roundness of the calipers truck aluminum alloy wheel hub need to be strictly controlled, especially the roundness control.

[0004] The existing roundness deformation measurement method is measured by using a vernier caliper or a bridge ruler, and the shaping machine is used for shaping, which is inconvenient to operate. UTILITY MODEL CONTENTS

[0027] The utility model will be further explained in detail below in combination with the drawings of the specification and the specific embodiment.

[0028] Referring to the drawings Figure 1 As shown in the drawings, the embodiment provides a cab aluminum alloy wheel heat treatment roundness gauge, which comprises an outer segment roundness gauge 10 and a middle segment roundness gauge 20. When the outer segment roundness gauge 10 is used to measure the roundness deformation of the cab aluminum alloy wheel 40, the outer segment roundness gauge 10 is used to measure the outer segment of the cab aluminum alloy wheel 40. Correspondingly, when the middle segment roundness gauge 20 is used to measure the roundness deformation of the cab aluminum alloy wheel 40, the outer segment roundness gauge 10 is used to measure the middle segment of the cab aluminum alloy wheel 40.

[0029] In the embodiment, the outer segment roundness gauge 10 and the middle segment roundness gauge 20 are used in pairs to detect the roundness deformation of the outer segment and the middle segment of the cab aluminum alloy wheel 40 to be detected, respectively.

[0030] In combination with the drawings Figure 1 to the drawings Figure 3 As shown in the drawings, the outer segment roundness gauge 10 comprises an outer segment roundness gauge handle 102 and an outer segment roundness gauge annular detection surface 101. The outer segment roundness gauge annular detection surface 101 is installed at the bottom end of the outer segment roundness gauge handle 102, and the outer segment roundness gauge annular detection surface 101 has a hollow annular shape. Similarly, the middle segment roundness gauge 20 comprises a middle segment roundness gauge handle 202 and a middle segment roundness gauge annular detection surface 201. The middle segment roundness gauge annular detection surface 201 is installed at the bottom end of the middle segment roundness gauge handle 202, and the middle segment roundness gauge annular detection surface 201 has a hollow annular shape. The length of the outer segment roundness gauge handle 102 is greater than the length of the middle segment roundness gauge handle 202.

[0031] Referring to the drawings Figure 4 As shown in the drawings, the cab aluminum alloy wheel heat treatment roundness gauge in the embodiment is also provided with an aluminum round hammer 30, which is used to correct the shape of the cab aluminum alloy wheel 40.

[0032] In this embodiment, the aluminum hammer 30 includes a hammer handle 302 and a hammer 301 fixedly installed at the bottom end of the hammer handle 302, and the hammer 301 and the hammer handle 302 are integrally formed by a cast aluminum process. In some embodiments, in order to prevent the hammer handle 302 and the hammer 301 from being separated, a steel pipe is used to make the hammer handle 302 on the aluminum hammer 30, and a stopper block is welded on the steel pipe. An iron sheet model is used to complete the cast aluminum hammer, that is, the stopper block is embedded in the hammer 301, so that the hammer 301 can be prevented from falling off the hammer handle 302.

[0033] Referring to the drawings Figure 5 As shown, when measuring the roundness deformation, the middle segment roundness gauge sleeve is clamped on the solution heat treatment quenched blank of the cab car aluminum alloy hub 40, and the thick and thin gauge 50 is inserted into the deformation gap between the middle segment roundness gauge 20 and the rim. The thickest (including the total thickness of the stacked thick and thin gauge 50 measuring piece) that can be inserted is the roundness deformation, and if the value exceeds the process requirement, the deformation part needs to be corrected by the aluminum hammer 30. When using the outer segment roundness gauge 10, the outer segment of the rim is measured, and the measurement principle and correction method are the same as those of the middle segment roundness gauge 20, which will not be described again here.

[0034] The outer segment roundness gauge 10 is designed with the same shape angle as the detection surface of the outer segment of the cab car hub (that is, the outer shape of the outer segment roundness gauge annular detection surface 101 is the same as the outer shape of the detection surface of the outer segment of the design specification cab car hub), which can more accurately correct the roundness measurement machine with the same shape. The outer segment roundness gauge 10 is used as a master mold, and the aluminum hammer 30 is used to correct the bulging deformation part on the outer side of the rim corresponding to the outer segment roundness gauge 10. The outer segment roundness gauge 10 needs to have sufficient thickness and width to withstand the force of the aluminum hammer 30 and to ensure that it does not deform in use. The outer segment roundness gauge handle 102 is made of steel.

[0035] The middle segment roundness gauge 20 is designed with the same shape angle as the detection surface of the middle segment of the cab car hub (that is, the outer shape of the middle segment roundness gauge annular detection surface 201 is the same as the outer shape of the detection surface of the middle segment of the design specification cab car hub), which can more accurately correct the roundness measurement machine with the same shape. The middle segment roundness gauge 20 is used as a master mold, and the aluminum hammer 30 is used to correct the bulging deformation part on the outer side of the rim corresponding to the middle segment roundness gauge 20. The middle segment roundness gauge 20 needs to have sufficient thickness and width to withstand the force of the aluminum hammer 30 and to ensure that it does not deform in use. The middle segment roundness gauge handle 202 is made of steel.

[0036] By adopting the heat treatment roundness correction gauge for the cab car aluminum alloy wheel hub, the outer section roundness correction gauge 10 and the middle section roundness correction gauge 20 are matched, the positions of the cast deformation or the spinning deformation of the aluminum alloy wheel hub are measured and corrected in a targeted manner, the deformation degree of the aluminum alloy cab car wheel rim is measured and controlled through the roundness correction gauge, and the wheel rim is orthopedically corrected through the roundness correction gauge as a reference circle, and the operation is simple.

[0037] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Therefore, if these modifications and variations of the present application belong to the scope of the claims of the present application and equivalent technologies, the present application also intends to include these modifications and variations.
