Description

Technical Field

[0001] This utility model relates to the field of dimensional inspection technology, and more specifically, to a device for inspecting the dimensions of automobile wheel spokes. Background Technology

[0002] The cross-sectional area of ​​a car wheel spoke is the smallest and the force per unit area is the largest at its narrowest point. The structural strength of the spoke is determined by the position with the smallest cross-sectional area. Therefore, the focus of quality inspection on wheel hub spokes is the width of the narrowest point. However, because the side of the spoke is a smoothly transitioning arc surface, it is not easy to locate the narrowest area of ​​the spoke during inspection. The existing testing method is for inspectors to determine the inspection position by visual judgment and then clamp the point with vernier calipers, which has a great deal of subjectivity and arbitrariness.

[0003] To address the aforementioned issues, patent document publication number CN207850243U discloses a wheel hub spoke width measuring device, comprising an arc-shaped portion and a radial portion; the tolerance marking portion includes an upper tolerance mark and a lower tolerance mark; the reference mark, upper tolerance mark, and lower tolerance mark are all radially arranged along the inner arc cylindrical surface, and the distances of the three marks to the inner arc cylindrical surface correspond to the distances from the spoke detection area of ​​the wheel hub to the circumferential surface of the wheel lip; the arc length from the reference mark to the upper tolerance mark is equal to the upper tolerance dimension of the spoke in the wheel hub to be tested, and the arc length from the reference mark to the lower tolerance mark is equal to the lower tolerance dimension of the spoke in the wheel hub to be tested. This measuring device can determine the reference position for measurement, thus ensuring the objectivity of the measurement results and avoiding the arbitrariness of subjective judgment in the prior art.

[0004] However, it still has some shortcomings in actual use. For example, the detection device can only detect the width of the spokes, but it is not convenient to detect the diameter of the spokes, resulting in incomplete detection data of the spokes and certain limitations in its use.

[0005] Therefore, a device for detecting the dimensions of automobile wheel spokes was proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automobile wheel spoke size detection device to solve the problem that the prior art detection device can only detect the width of the wheel spokes, but is not convenient to detect the diameter of the wheel spokes, resulting in incomplete detection data of the wheel spokes and certain limitations in use.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for detecting the dimensions of automobile wheel spokes, comprising...

[0008] Base plate;

[0009] A flip-up fixing assembly is disposed on the top of the base plate;

[0010] The spoke body has its outer surface detachably connected to the center of a reversible fixing assembly;

[0011] The rotatable fixing assembly includes a slide groove, the bottom of which is fixedly connected to the top of the base plate. A connecting frame is fixedly connected to the side of the slide groove, and an electric telescopic rod is fixedly connected to the lower part of the top of the connecting frame. A rack is slidably installed inside the slide groove, and the top of the rack is fixedly connected to the bottom of the electric telescopic rod. A rotating rod is rotatably connected to one side of the connecting frame, and a gear is fixedly sleeved on the outer surface of the rotating rod. The gear meshes with the rack. A first electric push rod is fixedly connected to the end of the rotating rod away from the connecting frame. A clamping plate is fixedly connected to the end of the first electric push rod away from the rotating rod, and the side of the clamping plate away from the first electric push rod is detachably connected to the outer surface of the wheel spoke body.

[0012] It also includes a detection component, which is disposed on the top of the base plate.

[0013] The detection component includes a second electric push rod, which is fixedly mounted on the top of the base plate via a support frame. One end of the second electric push rod is fixedly connected to a sliding frame, and a motor is fixedly mounted on the top of the sliding frame. A lead screw is rotatably connected inside the sliding frame, and the top end of the lead screw is fixedly connected to the output end of the motor. Two movable blocks are slidably mounted inside the sliding frame, and the interior of each of the two movable blocks is threaded to the outer surface of the lead screw. A strip plate is fixedly connected to the side of each of the two movable blocks away from the sliding frame.

[0014] The detection assembly further includes a laser sensor, a receiver, and a processing terminal. The laser sensor is fixedly installed on the top of one of the strip plates, the receiver is fixedly installed on the bottom of the other strip plate, and the processing terminal is fixedly installed in front of the base plate. The processing terminal is electrically connected to the strip plate and the receiver.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, a base plate, a flip-up fixing component, and a spoke body are set up. The spoke body is placed in the middle of the flip-up fixing component. The first electric push rod is activated, which drives the clamping plate to clamp the spoke body. At this time, the thickness of the spoke body can be detected. The electric telescopic rod is activated, which drives the rack to slide inside the slide groove, thereby driving the gear to rotate. This causes the rotating rod to drive the first electric push rod and the clamping plate to rotate, thereby driving the spoke body to rotate 90 degrees. At this time, the diameter of the spoke body can be detected. Through the above structure, the thickness and diameter of the spoke body can be detected, with a wider range of detection parameters and more comprehensive detection data.

[0017] The detection assembly is set up, and the second electric push rod is activated to bring the two strip plates close to the spoke body. Then, the motor is started, and the motor drives the lead screw to rotate, causing the two movable blocks to slide inside the sliding frame. This causes the two strip plates to be clamped at the edge of the spoke body. The laser sensor emits infrared light, which is received by the receiver, and the signal is transmitted to the processing terminal. The processing terminal converts the signal into specific numerical values ​​for display. Through the above structure, the size of the spoke body is detected by infrared detection, achieving more accurate detection data and a more convenient detection process. Attached Figure Description
