Description

Technical Field

[0001] The invention relates to the technical field of gear plate mould processing, and in particular to a grinding device and a grinding process thereof for gear plate mould processing. Background Art

[0002] Thread heads usually refer to one of the tools used for thread processing, also known as thread cutters. They are designed to form threads on the surface of a workpiece and are commonly used in the field of metal processing, such as in machining, turning and milling. After the thread head is processed, it needs to be ground to increase the accuracy. After grinding, it needs to be inspected. This process is time-consuming and manual inspection requires secondary clamping.

[0003] During the grinding and inspection process of the threaded core head, because the tooth grooves are relatively fine, positioning and adjustment must be performed after each clamping to align the processing tool with the tooth grooves, which takes a lot of time and affects the improvement of processing efficiency. At the same time, inspection cannot be carried out immediately after processing, and rework and repair will take a lot of time.

[0004] The patent application document with publication number CN116117244A discloses a mold for processing a drawer gear and a method of using the same, which relates to the field of gear processing technology, and includes a mounting frame, a first positioning mechanism, a second positioning mechanism, a gear connector and a bidirectional grinding assembly; when the bidirectional grinding assembly moves from the first positioning mechanism toward the second positioning mechanism to achieve tooth groove grinding, the first positioning mechanism rotates 72° and then, under the meshing action of the adjustment gear, the next group of gears to be ground rotate and move to the grinding station, and the tooth groove grinding is achieved by moving the bidirectional grinding assembly from the second positioning mechanism toward the first positioning mechanism. When the first group of gears to be ground rotates to the grinding station again, the first group of gears to be ground rotates so that the next pair of tooth grooves are aligned with the grinding plate to achieve tooth groove grinding.

[0005] The above technical solution can realize the grinding of two tooth grooves at the same time through the one-way movement of the bidirectional grinding edge assembly. The gear can be ground twice after one rotation of the gear. However, the gear cannot be tested while being ground. If the subsequent test fails, it needs to be re-clamped and ground again, which is time-consuming and labor-intensive. Summary of the invention

[0006] In view of this, the present invention provides a grinding device and a grinding process for gear plate mold processing, aiming to solve the technical problem in the prior art that the gear plate groove cannot be detected while grinding the gear plate groove.

[0007] In order to solve the above technical problems, the present invention provides a grinding device for processing a tooth plate mold, comprising a base, a rotating shaft arranged on the base and driven to rotate by a first driving source, and a threaded core head fixedly connected to the rotating shaft; a grinding mechanism and a detection mechanism are provided on one side of the threaded core head;

[0008] The grinding mechanism comprises an outer peripheral disk driven by a second driving source, a chuck fixedly connected to the outer peripheral disk, and a grinding knife rotatably connected to the chuck and capable of grinding the tooth groove of the thread core head; the grinding knife is driven to rotate by a third driving source, the first driving source and the second driving source are both slidably connected to the base, and the sliding direction of the first driving source is perpendicular to the sliding direction of the second driving source;

[0010] By adopting the above technical solution, the first driving source drives the thread core head to rotate. When the thread core head moves to contact the first detection knife, the first detection knife contacts or collides with the side wall of the tooth plate groove, and transmits the collision information to the first lever micrometer. After the first lever micrometer shakes, it indicates the error size. According to the indicated information, it can indicate the processing status of the tooth plate groove, and determine whether the tooth plate groove is qualified. As the thread core head moves, the grinding knife grinds the tooth plate groove. When the tooth plate groove exits, the first detection knife detects the tooth plate groove again, and the first lever micrometer feeds back the detection information. The present invention can grind the tooth plate groove while detecting the tooth plate groove. After detection, there is no need to clamp and grind again, which improves the efficiency of detection and grinding.

When the thread core head returns, the grinding knife grinds the tooth groove again, and the first detection knife detects the tooth groove again. Through multiple detections, the detection accuracy can be improved.

The grinding knife 15 is driven to rotate by the third driving source 23, which is the spindle motor of the engraving machine. The third driving source 23 is fixedly connected to the outer side of the arc disk 11. The driving shaft of the third driving source 23 passes through the chuck 16 and is fixedly connected to the grinding knife 15, which can drive the grinding knife 15 to rotate and grind the tooth plate groove. The structural schematic diagram during grinding is shown in FIG. Figure 4 shown.

[0044] like Figure 1 As shown, the first driving source 1 and the second driving source 4 are both slidably connected to the base 7, and the sliding direction of the first driving source 1 is perpendicular to the sliding direction of the second driving source 4; the base 7 is provided with a first dovetail plate 8 and a second dovetail plate 6 perpendicular to the first dovetail plate 8, the first dovetail plate 8 is slidably connected with a first dovetail groove 9, the first driving source 1 is fixedly connected to the first dovetail groove 9, the second dovetail plate 6 is slidably connected with a second dovetail groove 5, the second driving source 4 is fixedly connected to the second dovetail groove 5, the first dovetail groove 9 is driven by a first linear drive, and the second dovetail groove 5 is driven by a second linear drive, the first linear drive and the second linear drive are cylinders or hydraulic cylinders, which are not drawn in the figure.

When the thread core head 3 moves to contact the first detection knife 19, the first detection knife 19 contacts or collides with the side wall of the tooth plate groove, and transmits the collision information to the first lever micrometer 22. After the first lever micrometer 22 shakes, it indicates the error size. According to the indicated information, it can indicate the processing status of the tooth plate groove, and determine whether the tooth plate groove is qualified. As the thread core head 3 moves, the grinding knife 15 grinds the tooth plate groove. When the tooth plate groove exits, the first detection knife 19 detects the tooth plate groove again, and the first lever micrometer 22 feeds back the detection information. This embodiment can grind the tooth plate grooves while inspecting them. There is no need to clamp and grind them again after inspection, which improves the efficiency of inspection and grinding.

When the thread core head 3 returns, the grinding knife 15 grinds again, and the first detection knife 19 detects again. The tooth groove can be detected and ground simultaneously without multiple disassembly and clamping, thereby improving the detection efficiency, multiple detections, and improving the detection accuracy.
