Description

Technical Field

[0001] The utility model relates to the field of space dimension measuring tools, in particular to a measuring tool for measuring the space dimension of a steering knuckle. Background Art

[0002] The steering knuckle is one of the main parts on the steering axle of a car. The steering knuckle is like a key hub in the vehicle's steering system. It is an important component connecting the wheels and the vehicle suspension. It bears the steering responsibility of the vehicle during driving, enabling the vehicle to flexibly change its direction of travel. During the vehicle's steering process, the steering knuckle cooperates with the vehicle's steering rod and vehicle steering arm components to complete the steering action of the wheel, thereby changing the vehicle's direction of travel.

[0003] Since the dimensional accuracy of the steering knuckle mounting hole directly affects the vehicle's steering performance and driving stability, the steering knuckle needs to be accurately measured before it is installed on the vehicle. After the steering knuckle is produced, it is usually fixed on a testing stand, and the inspector uses a vernier protractor to measure the angle between any two sets of steering knuckle arms on the steering knuckle. The inspector uses the base measuring leg of the vernier protractor to fix the center of the circle at the end of the steering knuckle, and then measures the angle value between the two sets of steering knuckle arms by moving the movable measuring leg.

[0004] The inspector reads the measured value detected by the vernier protractor and compares it with the qualified value of the steering knuckle arm to determine whether the steering knuckle produced is qualified. Since the vernier protractor is used to measure the steering knuckle arm angle, it is cumbersome and inconvenient for the inspector to use. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a measuring tool for detecting the spatial dimensions of a steering knuckle, so as to solve the technical problem that the operation of using a vernier angle ruler to detect the angle of the steering knuckle arm is too cumbersome for the inspector.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a gauge for detecting the spatial dimensions of a steering knuckle, comprising a gauge body, a base fixed to the bottom of the gauge body, a measuring instrument movably mounted on the outer wall of the gauge body, a connecting block fixed to one side of the measuring instrument, a first probe and a second probe provided on one side of the connecting block, a measuring disk movably mounted on the outer wall of the gauge body, and angle lines provided on the outer wall of the measuring disk.

[0007] By adopting the above technical solution, the technical problem that the inspection personnel use vernier protractor to detect the angle of steering knuckle arm is too cumbersome is solved. The steering knuckle is put on the inspection fixture body, and the measuring instrument is rotated so that the first probe on the measuring instrument is in close contact with the surface of a group of steering knuckle arms on the steering knuckle. Then, the button is pressed and the measuring dial is rotated to adjust the measuring dial so that the zero scale line of the angle line on the measuring dial is aligned with the front view angle of the first probe. Finally, the measuring instrument is rotated so that the second probe on the measuring instrument is in contact with the surface of another steering knuckle arm, and the connecting block is faced. Then, the angle value indicated by the second probe on the measuring dial is read, thereby measuring the angle between the two groups of steering knuckle arms on the steering knuckle.

[0008] The utility model is further configured such that a steering knuckle is sleeved on the outer wall of the gauge body, and a support plate is fixed to the outer wall of the gauge body.

[0011] By adopting the above technical solution, after the steering knuckle is placed, the fixture is installed on the top of the inspection fixture body and the fixture is rotated. Since the fixture and the inspection fixture body are connected by threads, the fixture slowly presses down to fix the steering knuckle, so that the steering knuckle can be firmly tested on the inspection fixture body.

[0012] The utility model is further configured such that a rotating groove is provided on the outer wall of the gauge body, a rotating block is movably installed inside the rotating groove, and an end of the rotating block is connected to a measuring instrument.

[0013] By adopting the above technical solution, the rotating block provided on the inner wall of the measuring instrument is buckled in the rotating groove inside the gauge body, so that the measuring instrument can rotate freely on the outer wall of the gauge body.

[0014] The utility model is further configured such that a protrusion is fixed on the inner wall of the measuring disk, and an end portion of the protrusion is movably mounted inside the gauge body.

[0015] By adopting the above technical solution, a protrusion extends from the inner wall of the measuring disk, and the protrusion is movably embedded in the interior of the inspection fixture body, so that the inspection personnel can rotate the measuring disk, which is convenient for subsequent inspection of the steering knuckle arm angle of the steering knuckle.

[0016] The utility model is further configured such that a groove is provided inside the checking fixture body, a pressing and fixing disk is movably installed inside the groove, and a spring is connected to the bottom of the pressing and fixing disk.

[0017] By adopting the above technical solution, the extrusion fixing plate squeezes the protrusion inside the measuring plate, so that the measuring plate will not produce rotational deviation during the detection process. In addition, the extrusion fixing plate can move up and down in the groove, thereby realizing position control of the measuring plate.

[0018] The present invention is further configured such that a button is provided on the top of the gauge body, a connecting rod is fixed to the end of the button, and the connecting rod passes through the interior of the gauge body and is connected to the extrusion fixing disk.

[0019] By adopting the above technical solution, the inspector can press the button, which pushes the connecting rod downward, and the connecting rod drives the extrusion fixing plate to move to the bottom of the groove, thereby releasing the extrusion fixing plate from the measuring plate.

[0020] The present invention is further configured such that the angle line is provided with scale marking lines from 0° to 180°.

[0021] By adopting the above technical solution, the angle of the steering knuckle arm of the steering knuckle can be read from the measuring instrument by calculating the angle value indicated by the first probe for the first time and the angle value indicated by the second probe for the second time.

[0022] The present invention is further configured such that the initial state of the spring is an extrusion contraction state, and the spring always extrudes the extrusion fixing disk.

[0023] By adopting the above technical solution, when the button is not pressed, the spring always pushes the extrusion fixing disk upward, so that the extrusion fixing disk fixes the position of the measuring disk.

[0024] The present invention is further configured such that the bottoms of the first probe and the second probe extend to the bottom end of the measuring disk, and the first probe and the second probe can indicate the position of the angle line on the measuring disk.

[0025] By adopting the above technical solution, the tops of the first probe and the second probe can contact the surface of the steering knuckle, and the bottoms of the first probe and the second probe extend to the bottom end of the measuring disk, so that the first probe and the second probe can indicate the angle line on the measuring disk, making it convenient for the inspector to read the angle value from the measuring disk.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1.

The steering knuckle is placed on the gauge body, the measuring device is rotated so that the first probe on the measuring device is in close contact with the surface of a group of steering knuckle arms on the steering knuckle. Then, by pressing a button, the measuring dial is rotated and adjusted so that the zero scale line of the angle line on the measuring dial is aligned with the front-view angle of the first probe. Finally, the measuring device is rotated so that the second probe on the measuring device is in contact with the surface of another steering knuckle arm. The connecting block is then viewed frontally, and the angle value indicated by the second probe on the measuring dial is read, thereby measuring the angle between the two groups of steering knuckle arms on the steering knuckle.

[0028] 2. The utility model is provided with a button, a connecting rod, an extrusion fixing disk, a spring, and a protrusion. When the button is pressed, the button pushes the extrusion fixing disk downward through the connecting rod, and the extrusion fixing disk moves to the bottom of the groove. At the same time, the extrusion fixing disk squeezes the spring downward, and then the measuring disk is rotated to align the zero scale line of the angle line on the measuring disk with the front view angle of the first probe. Then, the button is released, and the spring pushes the extrusion fixing disk upward to reset. The extrusion fixing disk squeezes the bottom of the protrusion on the inner wall of the measuring disk upward, so that the measuring disk will not rotate during detection and use.
