Description

Technical Field

[0001] The present 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, and 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] Dimensional measurement and testing 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 testing devices include calipers:

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

[0005] Type: Vernier caliper: measures dimensions by the scale difference between the vernier and main scale; Digital caliper: uses an electronic display to display measurement results, with high accuracy and easy to read; Internal caliper and external caliper: used to measure internal and external diameters respectively. Vernier caliper is a common measuring tool, a measuring instrument for measuring length, internal and external diameters, and depth. The vernier caliper consists of a main scale and a sliding vernier attached to the main scale; viewed from the back, the vernier is a whole, and the depth gauge is connected to the vernier scale to measure the depth of grooves and barrels.

[0006] The main scale is generally in millimeters, while the vernier has 10, 20 or 50 divisions. According to the different 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 jaws and the outer measuring jaws. The inner measuring jaws are usually used to measure the inside diameter, and the outer measuring jaws are 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, it has 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. The metering component can only move 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 position due to external force factors. It is stable to use 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. No additional locking step is required, and the inner angle of the workpiece to be measured can be accurately measured. Only the rotation angle of one inner measuring claw needs to be calculated to obtain the inner angle of the workpiece to be measured. 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 through calculation. When the first rotating block is in a state of being parallel to the inner measuring claw of the main scale, the first rotating block is locked.

[0009] The above two existing technologies have the following disadvantages:

[0010] Existing technologies do 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, and 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 not slide normally.

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

[0056] Specifically, such as Figure 8 As shown, sliding blocks 801 are fixedly mounted on both the upper and lower sides of the movable seat 8. The sliding blocks 801 are slidably engaged with the inner wall of the chute 703. A tension spring 802 is fixedly mounted on one end of the sliding block 801 located within the movable seat 7. The other end of the tension spring 802 is fixedly mounted on the inner wall of the chute 703.

The output end of the motor 901 is fixedly connected to a rotating column 902. A sleeve hole 903 is formed at one end of the rotating column 902. A movable frame 904 is slidingly provided on the inner wall of the sleeve hole 903. The movable frame 904 is fixedly connected to the cleaning brush roller 10. When the rotating column 902 connected thereto is driven to rotate by the motor 901, the rotating column 902 drives the movable frame 904 to rotate through the sleeve hole 903, so that the movable frame 904 drives the connected cleaning brush roller 10 to rotate.

[0058] A limit ring 905 is rotatably connected to the inner wall of one side of the movable frame 904, and one end of the limit ring 905 is fixedly connected to a push-pull rod 906.

When the rotating column 902 rotates, the annular beveled groove 908 can drive the push-pull rod 906 to move back and forth, so that the push-pull rod 906 drives the connected limit ring 905 to move back and forth, thereby driving the cleaning brush roller 10 connected to the movable frame 904 to move back and forth.

[0060] Working principle, when in use: when it is necessary to clean the surface of the object to be measured and then measure it, press the positioning rod 401 so that the positioning rod 401 moves out of one of the positioning holes 302, then the rotating frame 4 can be rotated, and under the action of the spring B402, the positioning rod 401 is inserted into the other positioning hole 302 for limiting and fixing;

[0061] Then, the two cleaning brush rollers 10 are adjusted according to the size of the object to be measured. By turning the knob 504, the knob 504 drives the connected universal joint 503 to rotate, which drives the connected rotating shaft 501 to rotate, so that the two worms 502 on the rotating shaft 501 drive the worm gear 505 to rotate, so that the worm gear 505 drives the connected connecting rod group 506 to rotate, so that the connecting rod group 506 drives the two adjustment seats 6 to separate;

[0062] Then, the electric push rod 702 is used to drive the connected moving base 7 to move a suitable distance, and then the two cleaning brush rollers 10 are placed on the surface of the object to be measured, sandwiching the object to be measured in the middle. At this time, under the action of the tension spring 802, the cleaning brush rollers 10 can be closely attached to the surface of the object;

[0063] Then, the motor 901 is used to drive the connected rotating column 902 to rotate. At this time, the rotating column 902 drives the movable frame 904 to rotate through the sleeve hole 903, so that the movable frame 904 drives the connected cleaning brush roller 10 to rotate. Then, when the rotating column 902 rotates, it can drive the push-pull rod 906 to move back and forth through the annular inclined groove 908, so that the push-pull rod 906 drives the connected limit ring 905 to move back and forth, thereby driving the cleaning brush roller 10 connected to the movable frame 904 to move back and forth, thereby improving the grinding and cleaning efficiency;

[0064] After cleaning the surface of the object to be measured, retract the cleaning brush roller 10, and then retract the rotating frame 4 into the storage seat 3. When not needed, press the block 201 to retract the block 201 into the mounting head 2, so that the mounting head 2 can be removed and measured using the vernier caliper 1.
