Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive parts inspection technology, and in particular to a rapid comprehensive inspection tool for automotive wheel brackets. Background Technology
[0002] In the automotive parts manufacturing industry, wheel brackets are key load-bearing components, and their machining accuracy directly affects the safety performance of the entire vehicle.
[0003] Traditional inspection methods primarily rely on coordinate measuring machines (CMMs) and distributed specialized fixtures, which have significant technical limitations. While CMMs offer high accuracy, their inspection efficiency cannot meet the cycle time requirements of modern production lines, and the purchase and maintenance costs of such equipment are high. Distributed fixture solutions, although relatively cheaper, require multiple clamping and positioning operations, increasing inspection time and potentially affecting measurement accuracy due to repeated positioning errors. This is especially true for complex bracket parts containing multiple sets of mounting holes, tapered holes, and special angular structures. Traditional inspection methods often require multiple steps, such as hole diameter measurement, positional accuracy testing, and end face distance verification. This sequential inspection mode has become a bottleneck restricting the improvement of production efficiency.
[0004] With the automotive industry's increasing demands for parts inspection efficiency, the development of comprehensive inspection fixtures that can achieve rapid clamping, accurate positioning, and integrate multiple inspection functions has become an urgent need for the development of parts inspection technology.

[0022] The purpose of this invention is to provide a comprehensive inspection tool for automobile wheel brackets, which can increase the inspection efficiency and improve the inspection accuracy of automobile wheel brackets.
[0023] Example 1:
[0024] This embodiment provides a comprehensive inspection tool for automobile wheel brackets, comprising: a workpiece, the workpiece being irregularly shaped; a worktable, the worktable being a horizontally arranged plate-like structure; a bottom positioning component, the bottom positioning component including a base 2 and a protrusion, the base 2 being fixed on the worktable, the protrusion being fixed on the upper surface of the base 2 and being an upwardly protruding structure; a top limiting component, the top limiting component being used to limit the vertical displacement of the workpiece, the top limiting component including a pressure head; a side limiting component, the side limiting component being used to limit the rotation and lateral deviation of the workpiece, the side limiting component including a detection pin; and a connecting component, one end of the connecting component being fixed to the top of the worktable.
[0025] Specifically, in order to improve detection efficiency and reduce repeatability errors, this embodiment provides a comprehensive inspection fixture for wheel brackets that can be clamped and inspected from multiple angles and directions, conforming to the shape of the workpiece (i.e., the car wheel bracket), and at specific positions. The worktable is equipped with multiple mechanisms, including limiting members that are fixed from the top, side, and bottom. The limiting members are connected to the worktable via connecting members.
[0026] In a preferred embodiment of this invention, one or more of the connectors are connected at one end to the worktable and at the other end to the top limiting member; one or more of the connectors are connected at one end to the worktable and at the other end to the side limiting member.
[0027] Specifically, the connector is used to position the installation height, alignment angle, and fixing strength of the limiting component, so as to improve the detection efficiency and accuracy. The connector connects the worktable and multiple limiting components to realize the clamping of the workpiece from multiple angles and dimensions, so as to facilitate the smooth detection.
[0028] In a preferred embodiment of this invention, the top surface of the protrusion includes a positioning surface 1, which is an annular surface structure.
[0029] Specifically, the protrusion has a complex multi-segment structure to provide the workpiece with fixing strength. The main body of the protrusion is a cylinder with an annular positioning surface 1 on the top surface, which is parallel to the horizontal plane so that the workpiece can be placed horizontally and can ensure balance and stability.
[0030] In a preferred embodiment of this invention, the raised top surface includes a positioning post, which is located at the center of the positioning surface 1, and the radius of the positioning post is the same as the radius of the inner circle of the positioning surface 1.
[0031] Specifically, the positioning post is a cylindrical structure set at the center of the positioning surface 1, and its radius is the same as the radius of the inner circle of the positioning surface 1. This forms a two-section concentric cylindrical structure with the upper and lower radii increasing from small to large. After the workpiece is installed on the positioning surface 1, the positioning post is inserted into the interior of the workpiece to provide support strength.
[0032] In a preferred embodiment of this invention, the pressure head is a strip-shaped structure arranged perpendicular to the horizontal plane, with the top of the pressure head connected to the connector and the bottom movably connected to the top of the workpiece.
[0033] Specifically, the pressure head limits the workpiece at the top by pressing vertically downwards.
[0034] In a preferred embodiment of this invention, the connector to which one or more of the side limiting members are connected has a through hole at its top, the size of which is consistent with that of the detection pin connected thereto.
[0035] In a preferred embodiment of this invention, one or more detection pins pass through the through hole and are slidably connected within the through hole.
[0036] Specifically, multiple detection pins are inserted into recessed positions on the workpiece itself for detection. Some of the connecting parts are equipped with through holes. The cylindrical inner diameter of the through holes can ensure that the cylindrical detection head of the detection pin can move within a fixed track and limit its path, so as to provide better detection efficiency and detection accuracy.
[0037] In a preferred embodiment of this invention, one end of the detection pin is movably connected to a hole on the outer surface of the workpiece structure; at least one pair of detection pins are arranged adjacently, cooperating with multiple adjacent holes.
