Description

Technical Field

[0001] This utility model belongs to the field of error detection technology, specifically relating to an online detection and compensation device for multi-process machining errors. Background Technology

[0002] Multi-process inspection is a testing method specifically applied in the field of mechanical manufacturing, targeting multiple processing steps of parts. It can detect the processing errors of each process in real time during the part processing, breaking the lagging mode of traditional "offline inspection after processing", realizing the integration of "processing-inspection-compensation", and ultimately ensuring the accuracy and quality of multi-processed parts, while improving processing efficiency and reducing the defect rate.

[0003] A search revealed that Chinese Patent Publication No. CN205843525U discloses a "Detection Head Assembly for a Thread Testing Machine for an Electromagnetic Valve Body". This assembly includes a first detection fixing connecting ring fixed to the lower end of a first detection head guide shaft support. A first detection head stepped shaft support is pinned to the lower end of the first detection fixing connecting ring. The first detection head stepped shaft has a countersunk hole inside. The outer wall of the first detection head stepped shaft is divided into three equal parts around its axis, with a keyway and a mounting hole. The mounting hole is located above the keyway and communicates with the countersunk hole. A shaft-shaped first detection head is inserted into the countersunk hole inside the first detection head stepped shaft. A first detection no-go gauge and a first detection go gauge are sequentially arranged downwards at the lower part of the first detection head. A first detection fixing block is inserted into the mounting hole. A first detection spring is pinned to the lower surface of the first detection head stepped shaft support and the surface of the first detection head stepped shaft. This testing machine can accurately detect thread size, has a high degree of automation, and saves labor. However, the following defects still exist: (1) The detection structure is weak, the error detection accuracy and timeliness are insufficient, the data collection range is limited, and it is impossible to accurately capture minor errors such as size and shape, and it cannot meet the high precision requirements of multi-process processing. (2) The device has poor adaptability, complex operation and maintenance and low efficiency. The operation process has no clear logic, the detection and adjustment steps are cumbersome, and the professional skills required of the operators are high. Ordinary personnel need long-term training to get started. The detection data is prone to deviation due to operation errors, which seriously affects the overall efficiency of multi-process processing.

[0004] To address this, an online detection and compensation device for multi-process machining errors is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the existing problems.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a multi-process processing error online detection and compensation device, comprising a device body, a clamping plate fixedly connected to one side of the device body, a support foot fixedly connected to one side of the clamping plate, a main insertion rod limited and snapped onto the inner ring surface of the device body, and a fixing block fixedly connected to one side of the device body.

[0007] A nut is fixedly connected to one side of the fixing block, a threaded rod is movably connected to one side of the nut, a fixing collar is fixedly connected to one side of the main insertion rod, a limiting collar is fixedly connected to one side of the fixing collar, a telescopic rod is fixedly connected to one side of the limiting collar, and a limiting insertion rod is fixedly connected to one side of the telescopic rod.

[0008] A connecting baffle is fixedly connected to one side of the limiting rod, a detection main board assembly is fixedly connected to one side of the connecting baffle, and a detection head assembly is fixedly connected to one side of the detection main board assembly.

[0009] As a preferred technical solution of this utility model, a plug-in opening is provided on one side of the main body of the device, and the size of the plug-in opening and the main plug rod are matched.

[0010] As a preferred technical solution of this utility model, an installation opening is provided on one side of the fixing collar, and the installation opening and the limiting collar are structurally compatible.

[0011] As a preferred technical solution of this utility model, a positioning plate is fixedly connected to one side of the support foot, and the positioning plate is symmetrically arranged with the vertical center line of the main body of the device as the axis of symmetry.

[0012] As a preferred technical solution of this utility model, the upper surface of the positioning plate is provided with positioning openings, and the number of positioning openings is multiple.

[0013] As a preferred technical solution of this utility model, the nut is connected to the device body through a fixing block, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The main insertion rod, with its matching insertion opening on one side of the device body, can be stably and securely engaged with the inner surface of the device body, providing a solid foundation for subsequent inspection. Next, a fixing collar fixed to one side of the main insertion rod, with its own fitting installation opening that matches the limiting collar structure, achieves precise assembly of the limiting collar, ensuring that the telescopic rod connected to the limiting collar can stably drive the limiting insertion rod to adjust its position. On the connecting baffle fixed to one side of the limiting insertion rod, a detection mainboard assembly and a matching detection head assembly are installed. With the flexible adjustment of the telescopic rod, the detection head assembly can be close to the surface of the machined part, collecting data such as dimensions and shape during multi-process machining in real time. The detection mainboard assembly quickly analyzes and judges the error situation, thus accurately capturing machining errors and avoiding batch non-conforming problems caused by the lag of traditional offline inspection, significantly improving the quality pass rate of multi-process machined parts. 2. The device is initially stabilized by a clamping plate fixed to one side of the main body and a support foot at the bottom. A symmetrically arranged positioning plate on one side of the support foot, with multiple positioning openings, can adapt to different sizes of processing equipment. Operators can quickly fix the device to the processing table or production line using these openings, eliminating the need for a custom-designed fixing structure and improving the device's adaptability. Regarding component adjustment and maintenance, nuts are fixed to one side of the main body via symmetrically arranged fixing blocks. These nuts are movably connected to threaded rods; rotating the threaded rods allows for fine-tuning of the relative position of the main body and surrounding structures, facilitating adaptation to different processing requirements. Furthermore, the snap-fit ​​structure between the main insertion rod and the insertion opening, and the fitting assembly of the fixing collar and the limiting collar, all employ modular design. If components such as the detection head assembly or telescopic rod are damaged later, they can be quickly disassembled and replaced without disassembling the entire device, reducing maintenance time and costs. In addition, the entire adjustment and testing process revolves around the core structure, with a clear operating logic. Ordinary operators can learn to use it after simple training, effectively reducing operational errors and improving the overall efficiency of multi-process processing. Attached Figure Description

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a multi-process processing error online detection and compensation device, including a device body 1, a clamping plate 2 fixedly connected to one side of the device body 1, a support foot 3 fixedly connected to one side of the clamping plate 2, a main insertion rod 7 limited and snapped onto the inner ring surface of the device body 1, a fixing block 16 fixedly connected to one side of the device body 1, and a nut 17 fixedly connected to one side of the fixing block 16.

[0019] In this embodiment, a plug-in opening 6 is provided on one side of the main body 1 of the device, and the plug-in opening 6 and the main plug rod 7 are matched in size. An installation opening 10 is provided on one side of the fixing collar 8, and the installation opening 10 and the limiting collar 9 are structurally matched.

[0020] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a threaded rod 18 is movably connected to one side of the nut 17, a fixing collar 8 is fixedly connected to one side of the main insertion rod 7, a limiting collar 9 is fixedly connected to one side of the fixing collar 8, and a telescopic rod 15 is fixedly connected to one side of the limiting collar 9.

[0021] In this embodiment, a positioning plate 4 is fixedly connected to one side of the support foot 3, and the positioning plate 4 is symmetrically arranged with the vertical center line of the device body 1 as the axis of symmetry. The upper surface of the positioning plate 4 is provided with a positioning opening 5, and there are multiple positioning openings 5.

[0022] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a limiting rod 14 is fixedly connected to one side of the telescopic rod 15, a connecting baffle 11 is fixedly connected to one side of the limiting rod 14, a detection main board assembly 12 is fixedly connected to one side of the connecting baffle 11, and a detection head assembly 13 is fixedly connected to one side of the detection main board assembly 12.

[0023] In this embodiment, the nut 17 is connected to the device body 1 via a fixing block 16, and the fixing block 16 is symmetrically arranged with the vertical center line of the nut 17 as the axis of symmetry.

[0024] Working principle: When using the device, the user aligns the main insertion rod 7 with the insertion opening 6 on one side of the device body 1, which matches its size, and secures the main insertion rod 7 to the inner ring surface of the device body 1, ensuring that the main insertion rod 7 is firmly fixed. Next, using the installation opening 10 on one side of the fixing collar 8, which matches the structure of the limiting collar 9, the limiting collar 9 is precisely assembled with the fixing collar 8 fixed on one side of the main insertion rod 7, ensuring that the two are tightly connected without loosening. Symmetrically arranged fixing blocks 16 are fixed on one side of the device body 1, and nuts 17 are installed on one side of the fixing blocks 16, ensuring that the nuts 17 pass through the fixing blocks 16. The device is stably connected to the main body 1. Then, the threaded rod 18 is movably connected to the nut 17 side to test the rotation flexibility of the threaded rod 18. At the same time, the support foot 3 is fixed on one side of the clamping plate 2, and the positioning plate 4 is installed on one side of the support foot 3 with the vertical center line of the main body 1 as the axis of symmetry. The overall assembly of the device is completed. Through the multiple positioning openings 5 ​​opened on the positioning plate 4 on one side of the support foot 3, the device is fixed to the processing equipment or workbench using bolts and other connecting parts. By utilizing the adaptability of the multiple positioning openings 5, the fixing position is adjusted according to the specifications of the processing equipment to ensure the overall stability of the main body 1 and avoid displacement during the processing. Simultaneously check the connection status between the clamping plate 2 and the main body 1 of the device to ensure the reliability of the device support structure. Start the detection main board assembly 12 and test its fixed stability with the connecting baffle 11. Control the extension and retraction of the telescopic rod 15 fixed on one side of the limit collar 9, and observe the smoothness of the movement of the telescopic rod 15 driving the limit insert 14 and the connecting baffle 11 to ensure that the detection head assembly 13 can be flexibly adjusted in position. At the same time, rotate the threaded rod 18, and through the cooperation of the nut 17 and the fixing block 16, fine-tune the relative position of the main body 1 of the device and the processing equipment so that the detection head assembly 13 is initially aligned with the area of ​​the part to be processed. According to the multi-process processing requirements of the part to be processed, the telescopic rod 15 is used to precisely control the limit. The insertion rod 14 moves, causing the connecting baffle 11, the detection main board assembly 12, and the detection head assembly 13 to move. This adjusts the detection head assembly 13 to align with the detection point of the first machining operation of the part. During this process, the position of the main body 1 can be further fine-tuned by rotating the threaded rod 18 to assist in the precise positioning of the detection head assembly 13. The machining equipment is then started to begin the first machining operation. Simultaneously, the detection head assembly 13 is in real-time close to the machining surface of the part, collecting machining data such as dimensions, shape, and position, and transmitting the data to the detection main board assembly 12. The detection main board assembly 12 quickly analyzes the data to determine if there are any machining errors in the current operation. After the first machining operation is completed... The telescopic rod 15 moves the detection head assembly 13 to the second process detection point, repeating the above data acquisition and analysis process until all processes are inspected online. Error data for each process is recorded throughout. When the main detection board assembly 12 detects a processing error in a process, it generates a compensation command based on the error data. The operator can rotate the threaded rod 18 and use the threaded engagement between the nut 17 and the fixing block 16 to fine-tune the position of the main body 1 and subsequent processing-related structures to achieve processing benchmark compensation. If the detection position needs to be adjusted to match the compensated processing state, the telescopic rod 15 can be used to readjust the position of the detection head assembly 13 to ensure accurate detection even after compensation. After completing the error compensation adjustment, the processing equipment is started to perform secondary processing on the current process. Simultaneously, the detection head assembly 13 collects processing data again and transmits it to the main detection board assembly 12. The main detection board assembly 12 compares the error data before and after compensation to determine if the compensation effect meets the standard. If the error is found to be erroneous... If the error still exceeds the allowable range, repeat the above compensation adjustment and verification steps until the error meets the processing accuracy requirements. If the error meets the standard, continue with the subsequent processing and inspection. After all processing steps are completed and the error detection is qualified, stop the operation of the main board assembly 12 and the inspection head assembly 13. Use the telescopic rod 15 to retract the limit plug 14, the connecting baffle 11 and the inspection components to the initial position. Rotate the threaded rod 18 to restore the main body 1 of the device to the standby position. Then loosen the connector at the positioning opening 5 on the positioning plate 4, disassemble the device from the processing equipment or keep it in a fixed state, check the snap-fit ​​status of the main plug 7 and the plug opening 6, and if there is any looseness, re-tighten it. Clean the processing debris on the surface of the inspection head assembly 13 to ensure the subsequent inspection accuracy. Check the fit of the fixing collar 8 and the limit collar 9, and whether the telescopic rod 15 has normal telescopic function. At the same time, clean the impurities in the positioning opening 5 on the positioning plate 4 to prepare for the next use.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
