Description

Height area table rule detects measuring tool structure
Technical Field
The utility model relates to an automobile parts makes the field, especially a novel height is taken table rule and is detected the technique.
Background
At present, in the field of machine manufacturing, especially in the field of automobiles, the dimensional accuracy of an assembly component is closely related to the qualification rate of the subsequent whole assembly process and the final assembly, the satisfaction of customers is directly influenced, the assembly component comprises a tool clamp, an assembly part is loaded, and the like, so that the detection of the assembly size becomes a crucial link in the whole production flow, the common detection mainly adopts means such as vernier calipers, a micrometer and three-coordinate measurement, and the defects of large detection deviation, long detection time and inconvenience for operation of detection personnel commonly exist in the detection.
In the production process of our company, three-coordinate measurement or vernier caliper measurement is always adopted for the dimension detection of the assembly parts, so that in order to improve efficiency and reduce measurement errors, companies decide to design related measurement tools by technical departments by leading, and a method for detecting the related dimensions of the high-pressure fuel pipe and the end cover or the oil inlet seat assembly part by using the novel height gauge-equipped measuring tool comes from the beginning.
The novel height gauge with the meter greatly reduces the time for a measurer to detect the assembly, and simultaneously reduces errors of measured data caused by human negligence.
Disclosure of Invention
In order to solve the problem that above-mentioned prior art exists, the utility model provides a height takes table rule to detect measuring tool structure adopts digital display percentage table cooperation spring and measures the piece and measure, has effectively reduced the product error, has improved production efficiency.
The utility model discloses the structure comprises parts such as connecting block subassembly 1, measuring block 2, measuring stick 3, percentage table joint 4, calibration block 5, percentage table 6, spring 7. The connecting block assembly 1 and the measuring block 2 are connected through screws, the measuring rod 3 and the spring 7 are arranged in the connecting block assembly 1 and the measuring block 2, and the connecting block assembly 1 and the measuring rod 3 are in clearance fit, so that the connecting block assembly and the measuring rod 3 can move up and down stably; the dial indicator 6 is fixed on the connecting block component 1 through the dial indicator joint 4, and the dial indicator joint 4 is in threaded connection with the connecting block component 1; the whole device is vertically arranged on a calibration block 5, and the calibration block 5 is mainly used for calibrating the detection measuring tool before measurement and calibrating to a zero position.
The utility model has the advantages that: this novel measuring tool structure not only can detect whether qualified according to the size of assembly part, and help in time adjusting the used anchor clamps of assembly according to detecting the size, it is more convenient, swift than the fixed measuring tool of traditional nothing table, and this utility model measuring tool can be according to detecting the different calibration blocks 5 of the different preparation of a detection size, has certain commonality.
Drawings
Fig. 1 is a schematic view of the cross-sectional structure of the present invention.
Fig. 2 is a schematic view of the sectional structure of the utility model during detection.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Firstly, as shown in fig. 1, before the product measurement, the practical measuring tool needs to be calibrated by using the calibration block 5, the calibration block 5 is manufactured according to the theoretical size of the part to be detected, the reading of the digital display dial indicator is zeroed, and the detection work is carried out after the calibration is correct.
Then, when measuring, as shown in fig. 2, the piece 8 to be detected is placed in the lower end measuring block 2, wherein the larger cylinder end face of the piece 8 to be detected, such as a step, is attached to the lower end face of the measuring block 2, the small cylinder protruding out of the larger cylinder end face enters the measuring block 2, the measuring rod 3 moves upwards under the compression of the piece 8 to be detected, the upper spring 7 is compressed, the compression is transmitted to the dial indicator 6 through the dial indicator connector 4, meanwhile, the dial indicator 6 is compressed by the spring in the lower table under the compression, the measuring head of the dial indicator moves upwards, and the reading appears on the digital display dial indicator. And judging the out-of-tolerance condition of the assembly part according to the reading during detection, if the reading is positive, indicating that the measured size is larger than a theoretical value, and if the reading is negative, indicating that the measured size is smaller than the theoretical value, and then judging whether the out-of-tolerance condition is caused according to the specific tolerance requirement of the product drawing.
In the structure of the measuring tool, the spring 7 only plays an auxiliary role, and the dial indicator joint 4 is assisted in the extension and contraction process of the measuring rod 3, wherein the dial indicator joint 4 has elastic force, but the elastic force is smaller. The dial indicator joint 4 is used for providing elastic force to compress and reset, and the service life of the dial indicator 6 is greatly influenced in the rapid measurement process. Therefore, the spring 7 is added as an auxiliary, and the spring 7 has a slightly larger elasticity, so that the compression time of the dial indicator joint 4 in the measurement process is slightly prolonged, and the dial indicator 6 is protected. On the other hand, the spring 7 is added, so that the lower end face of the measuring rod 3 can be completely attached to the piece to be detected 8 under the pressure of the spring 7 during measurement, and the accuracy of measurement is guaranteed.
Through batch use verification, the structure is high in stability, convenient and fast to measure, convenient to operate and high in measuring accuracy.
