Description

Technical Field

[0001] The utility model relates to the technical field of inspection tools, in particular to the technical field of multi-station inspection tools.

Background Art

[0002] The steering knuckle, also known as the "sheep's horn", is one of the important parts in the automotive steering axle, which can enable the vehicle to drive stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the load at the front of the vehicle, support and drive the front wheels to rotate around the kingpin to steer the vehicle. Under the driving state of the vehicle, it bears variable impact loads. There is a steel sleeve on the steering knuckle. After production, the steel sleeve needs to be measured to obtain its data. Currently, the traditional measurement method is to directly measure the product to be measured with a measuring tool and obtain the geometric dimensions of the product to be measured by manual reading, so as to determine whether the product meets the standard dimensions or is within the allowable error range.

[0003] However, the method of directly reading with a measuring ruler has low working efficiency. Secondly, the measurement results of measuring tools such as steel rulers and tape measures have low accuracy, and it is not easy to fix the position when measuring the diameter with a ruler. Multiple repeated operations are required to find the diameter of a circle, and the operation is difficult.

[0004] To solve the problems proposed in the background art, for example, the patent with application number CN201520493195.8 discloses an outer diameter special inspection tool, which includes a connecting rod, a reference frame, two movable support seats, a movable measuring frame and a micrometer. The reference frame, two movable support seats and the movable measuring frame are sequentially sleeved on the connecting rod, and the micrometer is fixedly arranged on the movable measuring frame. By adopting the setting of two movable support seats, it can be quickly fixed with the product to be measured to prevent slipping and loosening. The diameter of the product can be directly compared with the standard size, and a large number of products can be measured in a short time, improving the efficiency of the measurement work. Through the design of the micrometer, the measurement accuracy and accuracy can be improved. However, this structure still has the following defects:

[0005] This structure can only measure the outer diameter of the workpiece and cannot measure the height, groove diameter and large outer diameter of the workpiece. If measurement is required, the workpiece needs to be transferred to other measuring tools for detection, resulting in cumbersome operation and low working efficiency.

By using the first support base, the second support base, the third support base, the fourth support base, the first dial indicator, and the second dial indicator in cooperation, the present utility model can perform all-round measurement on the workpiece. First, zero the first dial indicator and the second dial indicator, that is, adjust the pointer to the zero scale position of the scale disk. Then place the workpiece on the first support base, and then make the probe on the first dial indicator contact the workpiece. The force on the workpiece will be transmitted to the pointer system through the support lever, causing the pointer to deflect. Then read the height of the workpiece and compare it with the standard data to determine whether the height of the workpiece is qualified. When the outer diameter of the workpiece needs to be detected, move the workpiece to the second support base so that the probe on the second dial indicator contacts the outer diameter of the workpiece, and then read the outer diameter of the workpiece and compare it with the standard data to determine whether the outer diameter of the workpiece is qualified. When the groove diameter of the workpiece needs to be detected, move the workpiece to the third support base so that the probe on the second dial indicator contacts the groove diameter of the workpiece, and then read the groove diameter of the workpiece and compare it with the standard data to determine whether the groove diameter of the workpiece is qualified. When the large outer diameter of the workpiece needs to be detected, move the workpiece to the fourth support base so that the probe on the second dial indicator contacts the large outer diameter of the workpiece, and then read the large outer diameter of the workpiece and compare it with the standard data to determine whether the large outer diameter of the workpiece is qualified. Therefore, this device can detect the height, outer diameter, groove diameter, and large outer diameter of the workpiece without transferring the workpiece to other tools, which is more practical, has higher processing efficiency, and is simple and convenient to operate. It solves the problem that the height, groove diameter, and large outer diameter of the workpiece cannot be measured, and if measurement is required, the workpiece needs to be transferred to other measuring tools for detection, resulting in more cumbersome operation.

[0035] During the working process of a multi-station inspection tool of the present utility model, first, zero the first dial indicator 9 and the second dial indicator 11, that is, adjust the pointer to the zero scale position of the scale disk. Then place the workpiece on the first support seat 3, and then make the probe on the first dial indicator 9 contact the workpiece. The force on the workpiece will be transmitted to the pointer system through the support lever, causing the pointer to deflect. Then read the height of the workpiece and compare it with the standard data to determine whether the height of the workpiece is qualified. When the outer diameter of the workpiece needs to be detected, move the workpiece to the second support seat 4 so that the probe on the second dial indicator 11 contacts the outer diameter of the workpiece, and then read the outer diameter of the workpiece and compare it with the standard data to determine whether the outer diameter of the workpiece is qualified. When the groove diameter of the workpiece needs to be detected, move the workpiece to the third support seat 5 so that the probe on the second dial indicator 11 contacts the groove diameter of the workpiece, and then read the groove diameter of the workpiece and compare it with the standard data to determine whether the groove diameter of the workpiece is qualified. When the large outer diameter of the workpiece needs to be detected, move the workpiece to the fourth support seat 6 so that the probe on the second dial indicator 11 contacts the large outer diameter of the workpiece, and then read the large outer diameter of the workpiece and compare it with the standard data to determine whether the large outer diameter of the workpiece is qualified. Therefore, this device can detect the height, outer diameter, groove diameter, and large outer diameter of the workpiece, and can be completed without transferring the workpiece to other tools, with stronger practicability, higher processing efficiency, and simple and convenient operation.
