Description

Technical Field

[0001] The invention belongs to the technical field of metering devices, and in particular relates to a metering detection device. Background Art

[0002] Metrology and testing devices are usually composed of multiple components and modules, which are used to accurately measure, record and monitor physical quantities (such as length, weight, temperature, voltage, flow, etc.). These devices are widely used in industry, laboratories, medical and other fields to ensure the accuracy and reliability of measurement results.

[0003] Dimension measurement and detection devices are mainly used to accurately measure the dimensions of objects, including length, width, thickness, diameter, angle, shape, etc., to ensure that the product meets the design and standard requirements. Common dimensional measurement and detection devices include calipers:

[0004] Application: Used to measure external and internal dimensions, depth, etc. of objects.

[0005] Type: Vernier caliper: measures size by the scale difference between the vernier and the main scale. Digital caliper: uses an electronic display to display the measurement results, with high accuracy and easy to read. Internal caliper and external caliper: used to measure the inner diameter and outer diameter respectively. Vernier caliper is a common measuring tool. It is a measuring tool for measuring length, inner and outer diameter, and depth. The vernier caliper consists of a main scale and a slidable vernier attached to the main scale. Viewed from the back, the vernier is a whole. The depth gauge is connected to the vernier scale, and can measure the depth of the groove and barrel.

[0006] The main scale is generally in millimeters, while the vernier has 10, 20 or 50 divisions. Depending on the divisions, the vernier caliper can be divided into 10-degree vernier caliper, 20-degree vernier caliper, 50-degree vernier caliper, etc. The vernier with 10 divisions is 9mm, 20 divisions is 19mm, and 50 divisions is 49mm. There are two pairs of movable measuring jaws on the main scale and vernier of the vernier caliper, which are the inner measuring jaw and the outer measuring jaw. The inner measuring jaw is usually used to measure the inside diameter, and the outer measuring jaw is usually used to measure the length and outside diameter. The vernier caliper has the characteristics of simple structure, easy use, medium accuracy and large measurement range. It can be used to measure the inside diameter, outside diameter, length, width, thickness, depth and hole spacing of parts. It has a wide range of applications and is a universal measuring tool. Through reasonable use and regular maintenance, it can be ensured to provide high-precision measurement results for a long time.

[0007] The prior art discloses some invention patents in the technical field of metering devices, among which the invention patent with application number CN202410187309.X discloses a metering and detection device. By setting the movement of the metering component to have a damping mode and a self-positioning mode, in the damping mode, the metering component has a damping force when moving, which is no different from the traditional usage mode. At the same time, the damping force can be adjusted and opened and closed according to actual needs, which is convenient for use in different measurement environments and needs. In the self-positioning mode, the metering component is always in a locked state, and the metering component can only be moved after the locking state of the metering component is released. After the movement is completed, the metering component can automatically lock the position to avoid the metering component from changing its position due to external force factors. The use is stable, and the usage mode can be adjusted according to the actual detection and metering needs, which improves the flexibility, adaptability and practicality of the device.

[0008] The invention patent with application number CN202411181824.3 discloses a multifunctional vernier caliper, which drives two inner measuring claws away from each other through a spring rod and fits tightly with the inner wall of the inner angle of the workpiece to be measured. At this time, the first rotating block drives the pointer to rotate to the angle position displayed on the scale ring to obtain the measurement result of the inner angle of the workpiece to be measured. The inner angle of the workpiece to be measured can be accurately measured without additional locking steps. The inner angle of the workpiece to be measured can be obtained by calculating the rotation angle of one inner measuring claw. The operation is simple and the accuracy is high. When measuring the outer angle of the workpiece, one surface of the workpiece to be measured is first tightly fitted on the top of the support block, and then the first rotating block drives the inner measuring claw to fit tightly with the other surface of the workpiece to be measured under the drive of the spring rod. At this time, the first rotating block drives the pointer to rotate to the angle position displayed on the scale ring, and the angle of the outer angle of the workpiece to be measured can be obtained by calculation. When measuring, in order to ensure the measuring accuracy, it is necessary to lock the angle of the first rotating block so that the inner measuring claw on the first rotating block is always parallel to the inner measuring claw on the main scale. At this time, the twist cap is rotated clockwise, and the twist cap drives the first rotating block to rotate clockwise through the fixed shaft until the first rotating block drives the push rod to rotate on the inner wall of the movable hole through the locking head to be parallel to the locking frame. At this time, the vernier fixing plate is moved away from the locking frame, that is, the locking block moves along the second movable groove rectangular through groove toward the inner wall of the depth gauge guide groove, and the push rod is gradually separated from the inner wall of the locking hole. At the same time, the locking frame gradually enters the inner wall of the locking hole under the action of the reset stretching of the reset spring until the locking frame completely enters the inner wall of the locking hole. At this time, because the locking frame is limited by the reset spring and can only move horizontally, the reset spring cooperates with the locking frame, the locking hole and the locking head to limit the rotation of the first rotating block, that is, at this time, the two inner measuring claws are arranged in parallel, which does not affect the normal use of the main scale and the vernier scale.

[0009] The above two prior arts have the following disadvantages:

[0010] The existing technology does not have a cleaning function. During the measurement process, if there is dust, oil, rust or other impurities on the surface of the measured object, it may affect the measurement accuracy. For example, oil or dust may affect the contact between the vernier caliper and the surface of the measured object, thereby affecting the accuracy of the reading. Especially in measurement situations with high precision requirements, tiny dirt may cause errors of several microns or even larger.

[0011] Hard objects, metal shavings or other contaminants on the surface of the measured object may scratch the measuring claws of the vernier caliper. Long-term use may cause the caliper's accuracy to decrease. The vernier caliper is prone to accumulate stains or metal shavings during the measurement process, which may not only affect the measurement results, but also require additional cleaning. Although the caliper itself may have some anti-rust treatment, if the surface dirt is not cleaned in time, long-term use may affect the life of the caliper and may even cause the vernier caliper to get stuck or fail to slide normally.

[0012] Based on this, the present invention designs a measurement and detection device to solve the above problems. Summary of the invention
