Description

Technical Field

[0001] This invention belongs to the field of machining and automatic detection technology and is applied to mechanical manufacturing production lines or CNC equipment clusters. Specifically, it is an intelligent zero-point positioning quick-change system, a mechanical manufacturing system and its working method. Background Technology

[0002] A zero-point positioning device is a unique positioning and locking mechanism that keeps the zero point (i.e., any reference point on the workpiece) constant or within acceptable tolerances when moving a workpiece from one station to another, one process to another, or one machine tool to another. This saves auxiliary time spent re-aligning the zero point, ensures work continuity, and improves work efficiency. Zero-point positioning devices are suitable for machining large batches of precision parts and have extensive applications in CNC machine tools, robotics, and intelligent manufacturing.

[0003] The zero-point positioning quick-change system mainly includes a quick-change pallet, a transfer device, a waiting device, and a quick-change device. The automation and intelligence levels of existing zero-point positioning quick-change systems need improvement. During use, the zero-point positioning device needs to automatically detect the zero-point positioning status, determine whether the zero-point positioning status is qualified, and issue an alarm for unqualified zero-point positioning status. Currently, there is no publicly available technical solution for remotely transmitting, diagnosing, issuing early warnings, and proposing reasonable maintenance recommendations via a wireless network for the aforementioned detection and recording results.

[0004] Therefore, there is an urgent need to develop and provide an intelligent zero-point positioning quick-change system, a mechanical manufacturing system, and its working method, with a high level of automation and intelligence. Its automatic zero-point positioning status detection device ensures reliable positioning through detection and early warning, and facilitates remote control. This is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides an intelligent zero-point positioning quick-change system, a mechanical manufacturing system, and its working method. The system boasts a high level of automation and intelligence. Its automatic zero-point positioning status detection device ensures the reliability of the zero-point positioning status through detection and early warning, and is also easy to remotely control.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A smart zero-point positioning quick-change system includes a quick-change pallet, a transfer device, a waiting device, a quick-change device, and a zero-point positioning base plate set on a workbench at a designated position on a mechanical manufacturing production line or CNC equipment cluster. The quick-change pallet includes a flat plate, positioning rivets, and a special clamp. The zero-point positioning base plate is provided with positioning circular holes that mate with the positioning rivets and surface air blowing cleaning holes. The system is characterized by further including an automatic zero-point positioning state detection device and a remote diagnostic device. The automatic zero-point positioning state detection device includes a positioning state airtightness detection module and a clamping force detection module. The positioning state airtightness detection module is used to introduce air at a given pressure after the quick-change pallet is in place. A pressure sensor built into the air inlet of the surface air blowing cleaning hole measures the inlet pressure value in real time and correlates it with different gaps between the top surface of the zero-point positioning base plate and the bottom surface of the quick-change pallet. The system compares the measured or calculated standard pressure value at the inlet to determine the gap size between the zero-point positioning base plate and the quick-change tray, thereby judging whether the zero-point positioning is qualified and issuing an alarm for unqualified zero-point positioning. The clamping force detection module is used to measure the magnitude of the tension force experienced by the positioning pin after the zero-point positioning operation is completed online in real time through a tension sensor, and compare it with the measured or calculated standard tension value to judge whether the zero-point positioning is qualified and issue an alarm for unqualified zero-point positioning. Both the automatic zero-point positioning status detection device and the remote diagnostic device include a wireless communication module. The remote diagnostic device also includes a diagnostic module, an early warning module, and a maintenance plan generation module, which are used to transmit the detection and recording results of the automatic zero-point positioning status detection device remotely in real time through a wireless network to realize remote diagnosis, early warning, and the submission of reasonable maintenance plans.

This module, after the quick-change tray is in place, introduces air at a given pressure. A pressure sensor built into the positioning hole inlet of the zero-point positioning base plate measures the inlet pressure in real time and compares it with the measured or calculated standard pressure values ​​corresponding to different annular average gaps between the positioning pin and the positioning hole of the zero-point positioning base plate. The system determines the size of the annular average gap between the positioning pin and the positioning hole of the zero-point positioning base plate. When the annular average gap exceeds the designed allowable value, the system issues an alarm, prompting the replacement of relevant parts.

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings:

[0037] See Figures 1-6 An embodiment of the intelligent zero-point positioning quick-change system of the present invention includes a quick-change pallet 1, a transfer device, a waiting device, a quick-change device, and a zero-point positioning base plate 2 set on a workbench at a designated position on a mechanical manufacturing production line or CNC equipment cluster 6. The quick-change pallet 1 is a combination of a flat plate, a positioning rivet 3, a special clamp, and a workpiece. The zero-point positioning base plate 2 is provided with a positioning circular hole 4 that cooperates with the positioning rivet and a surface air blowing cleaning hole 5. It also includes an automatic zero-point positioning status detection device and a remote diagnostic device. The automatic zero-point positioning status detection device includes a positioning status airtightness detection module and a clamping force detection module. The positioning status airtightness detection module is used to introduce air at a given pressure after the quick-change tray 1 is in place. Through a pressure sensor (not shown) built into the air inlet of the surface blowing cleaning hole 5, the inlet pressure value is measured in real time and compared with the measured or calculated standard pressure value of the inlet corresponding to different gaps between the top surface of the zero-point positioning base plate and the bottom surface of the quick-change tray. This determines the size of the gap between the zero-point positioning base plate and the quick-change tray, thereby judging whether the zero-point positioning status is qualified, and addressing unqualified zero-point positioning status. The system triggers an alarm for the zero-point positioning status. The clamping force detection module is used to measure the tension force experienced by the positioning pin after the zero-point positioning operation is completed online in real time using a tension sensor (not shown), and compares it with the measured or calculated standard tension value to determine whether the zero-point positioning status is qualified, and to trigger an alarm for unqualified zero-point positioning status. Both the automatic zero-point positioning status detection device and the remote diagnostic device include a wireless communication module. The remote diagnostic device includes a diagnostic module, an early warning module, and a maintenance plan generation module, which is used to simultaneously transmit the detection and recording results of the automatic zero-point positioning status detection device remotely through a wireless network in real time, so as to realize remote diagnosis, early warning, and the submission of reasonable maintenance plans.

[0038] Specifically: such as Figure 4As shown, the aforementioned automatic zero-point positioning state detection device also includes a zero-point positioning state error prediction module. This module is used to introduce air at a given pressure after the quick-change tray 1 is in place. The pressure sensor (not shown) built into the inlet of the positioning hole 4 of the zero-point positioning base plate 2 measures the inlet pressure value in real time and compares it with the measured or calculated standard pressure value corresponding to different annular average gaps between the positioning pull pin 3 and the positioning hole 4 of the zero-point positioning base plate 2. The module determines the size of the annular average gap between the positioning pull pin 3 and the positioning hole 4 of the zero-point positioning base plate 2. When the annular average gap exceeds the designed allowable value, the system alarms and prompts the replacement of relevant parts.

[0039] Furthermore, the aforementioned positioning rivet 3 is installed on the lower surface of the flat plate in the quick-change tray 1, and the special clamp and the workpiece are installed on the upper surface of the flat plate in the quick-change tray 1.

The aforementioned waiting device refers to the device that positions and stops the transfer device that transfers the quick-change pallet 1 to a designated location near the machine manufacturing production line or CNC equipment cluster 6, placing it in a waiting state so that the zero-point positioning operation can be smoothly implemented in the next step. The aforementioned AGV trolley 7 uses PLC automatic control for waiting; the semi-automatic balancing crane 10 uses a mechanical limit device installed on the mechanical track for waiting; and the roller trolley 11 uses a mechanical limit device installed on the ground on the machine tool operating side for waiting.

[0041] Furthermore, the quick-change device of the aforementioned AGV trolley 7 uses the AGV handling robot 8 to grasp and perform zero-point positioning operations; the quick-change device of the aforementioned semi-automatic balancing crane 10 uses the machine tool handling robot 9 to grasp and perform zero-point positioning operations.
