Description

Technical Field

[0001] This utility model belongs to the field of roller sleeve hole making technology, and in particular relates to a tool setting device for a special machine for making holes in a pin roller sleeve. Background Technology

[0002] The roller sleeve drilling machine is a specialized piece of equipment designed specifically for drilling holes in the pin sleeves of roller presses. In this application scenario, the number of pin holes to be drilled on a single roller sleeve is enormous, averaging around ten thousand. This undoubtedly places extremely high demands on the equipment's processing capacity and efficiency. Furthermore, the entire processing cycle for each roller sleeve is time-consuming, averaging 150 hours to complete. This means the equipment must be capable of long-term, continuous, and automated operation to meet production needs. However, in such high-intensity, long-duration processing, drill bit wear and replacement become unavoidable issues. Frequent drill bit replacements not only increase operational complexity but also directly impact production efficiency. More importantly, due to manufacturing deviations in drill bit length, coordinate repositioning is necessary after each drill bit replacement to ensure consistent drilling depth, which undoubtedly adds additional operating time and difficulty.

[0003] Currently, roller sleeve drilling machines primarily rely on manual operation for drill bit replacement and tool setting. This manual tool changing and setting process accounts for a significant portion of the entire processing cycle, approximately 20 hours. This undoubtedly has a significant negative impact on production efficiency. More seriously, the randomness of the starting point for manual tool setting leads to relatively large errors, and the accuracy of repeatable positioning cannot be effectively guaranteed. This clearly contradicts the fully automated, high-precision operation requirements of drilling machines. Therefore, improving the tool changing and setting process of roller sleeve drilling machines, and enhancing automation and positioning accuracy, has become crucial for improving production efficiency and meeting production demands. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a tool setting device for a special machine for drilling holes in column nail roller sleeves. This device enables automatic tool setting of the drill bit, ensuring that the drill bit can be quickly and accurately positioned at the predetermined drilling location after replacement. This significantly reduces the time required for tool setting, while also reducing the labor intensity of operators and improving product quality.

[0008] Furthermore, a second linear guide rail is horizontally mounted on the second fixed frame, and a second mounting bracket is mounted on the slider of the second linear guide rail. A second cylinder is mounted on the second fixed frame, and the piston rod of the second cylinder is connected to the second mounting bracket.

[0009] Furthermore, the detection end of the first sensor faces the mounting side of the first drill bit.

[0010] Furthermore, the detection end of the second sensor faces the mounting side of the second drill bit.

[0011] The advantages and technical effects of this invention are as follows: By adopting the above technical solution and setting up the first and second tool-setting assemblies, the device can achieve automatic tool setting of the first and second drill bits.

[0023] Work process:

[0025] (2) Tool positioning: The CNC machine tool moves the tool to the measurement position of the tool setting assembly.

[0026] (3) Measurement process: After the sensor inside the tool assembly detects the position of the tool, it records the specific size and position information of the tool.

[0027] (4) Data processing and calculation: The system calculates the actual position of the tool based on the collected signals and compares it with the ideal position.

[0028] (5) Compensation value update: Based on the calculation results, the system automatically updates the tool compensation value to ensure the accuracy of subsequent machining. The CNC system will convert the measurement results with the machine tool coordinate system to determine the initial offset value of the tool.
