Abstract
Description
Technical Field
[0001] The utility model relates to the field of grinding machines, in particular to a small double-sided grinding machine for processing measuring tool probes. Background Art
[0002] The stylus is a key component of high-precision measuring tools such as micrometers, height gauges, and length gauges. It is responsible for directly contacting the measured object and transmitting measurement data. The machining accuracy of the stylus is crucial to the overall measurement accuracy of the measuring tool, because any slight error may lead to inaccurate measurement results. The stylus is usually made of high-hardness materials to ensure its stability and wear resistance in long-term use. Precision machining and strict quality control are the basis for ensuring the performance and accuracy of the measuring tool. Therefore, during the manufacturing process, the machining accuracy of the stylus must meet very strict standards.
[0003] A grinder is a device used for material processing. It mainly uses friction to finely grind, polish or remove excess parts of the material surface. It is widely used in the processing of metals, plastics, glass, ceramics and other materials to improve surface finish, dimensional accuracy or achieve specific shape requirements. Grinding machines can be divided into various types such as plane grinders, cylindrical grinders, internal and external cylindrical grinders, etc., using different grinding methods and tools. They are usually equipped with high-speed rotating grinding wheels or abrasives to achieve precision processing. Precision control and operational stability are important indicators of grinder performance.
[0004] Normally, when measuring with a normal micrometer, the probe needs to penetrate deep into the gear teeth, and the measurement accuracy needs to reach 0.001mm. According to relevant standards, the manufacturing accuracy of the probe needs to reach 0.001mm. However, traditional probes on the market, including those of imported products, cannot meet the measurement requirements. The accuracy cannot be reduced, and processing needs to ensure strict geometric tolerances, which greatly increases the processing requirements and difficulty, resulting in low yield and high processing costs. Therefore, a small double-sided grinding machine for processing measuring tool probes is proposed to solve the above problems. Utility Model Content

The fork-shaped part 4 is used to connect and support the grinding disc 6. The support pin 5 is used to fix the grinding disc 6 to keep the grinding disc 6 stable. The grinding disc 6 is used to grind the micrometer probe 7. The clamp 12 is used to fix the support frame 13. The support frame 13 is used to fix and support the micrometer probe 7. The micrometer probe 7 is the detection head of the detection tool. The rear side of the fixed shaft sleeve 3 is fixedly connected to the front side of the support plate 11 to keep the fixed shaft sleeve 3 stable.

[0033] Working principle: When the device is used, the speed regulating motor 8 rotates to drive the connecting rod 1, connecting rod 2, connecting rod 3 9 and fork 4 to move, converting the rotary motion of the motor shaft into linear reciprocating motion. The grinding disc 6 is driven to move together through two support pins 5 on the fork 4. The function of the fixed sleeve 3 is to ensure that the reciprocating motion of the grinding disc has a high straightness. The holes on the support pins 5 and the fork 4 and the holes on the support pins 5 and the grinding disc 6 are clearance fit, and the clearance is large. The micrometer probe 7 is added. The workpiece is mounted on the support frame 13 and fixed on the workbench 10 by the clamp 12, and then is tightly attached to the grinding disc 6, with a certain pre-tightening force between the grinding disc 6 and the micrometer probe 7. As the grinding disc 6 reciprocates, the micrometer probe 7 is ground. During the grinding process, the pre-tightening force between the micrometer probe 7 and the grinding disc 6 will disappear and a gap will be generated. The operator needs to adjust it to ensure that the grinding continues and that the grinding disc 6 has multiple degrees of freedom and keeps in a follow-up state with the micrometer probe 7 during operation.
