[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0023] Embodiment 1 of this utility model:

[0024] The rapid relative measurement device for parts in the machining production line of this utility model embodiment is mainly used for measuring the workpieces produced by automated workpiece production equipment such as CNC machine tools. Through the cooperation of the parallel motion mechanism 2, the measuring mechanism 3 and the workpiece picking and placing mechanism 4, the rapid and accurate measurement of the workpiece is realized, so as to replace the existing workpiece measuring equipment and improve the convenience and accuracy of workpiece measurement.

[0025] like Figure 1 - Figure 5 As shown, a rapid relative measurement device for parts in a machining production line includes a frame 1, a parallel motion mechanism 2, a measuring mechanism 3, and a workpiece pick-and-place mechanism 4. A pick-and-place table 11 is provided on the frame 1, and the workpiece pick-and-place mechanism 4 is located on the pick-and-place table 11. The function of the workpiece pick-and-place mechanism 4 is to pick up and place workpieces, including standard parts and workpieces to be measured. The parallel motion mechanism 2 is located on the frame 1 and above the workpiece pick-and-place mechanism 4. The measuring mechanism 3 is connected to the parallel motion mechanism 2 and drives the measuring mechanism 3 to move through the parallel motion mechanism 2, thereby realizing the calibration of standard parts and the comparative measurement of workpieces.

[0026] With the above settings, the workpiece can be quickly measured simply by placing it on the workpiece removal mechanism. It is also highly versatile and can adapt to the measurement of different workpieces. Through the cooperation of the measuring mechanism 3 and the parallel motion mechanism 2, the workpiece can be measured quickly and accurately. It is also easy to combine with robotic arms to automate the measurement of parts.

[0027] like Figure 1 As shown, the frame 1 includes a base 12 and a working chamber 13. The working chamber 13 is located on the upper end of the base 12. The parallel hybrid mechanism and the measuring mechanism 3 are located in the working chamber 13. A pick-and-place platform 11 is formed on the top of the base 12. The workpiece pick-and-place mechanism 4 is located on the pick-and-place platform 11, which facilitates the pick-and-place of workpieces.

[0028] It should be noted that the working chamber 13 is a sealed enclosure, isolated by the lifting door 14, so that the working chamber 13 forms a stable testing environment, which can provide a stable environment for the comparison and measurement of parts to ensure its measurement accuracy.

[0029] Specifically, Figure 2 - Figure 4 As shown, the workpiece loading and unloading mechanism 4 includes a linear module 41 and a clamping plate 42. The linear module 41 is set on the loading and unloading platform 11, with part of the linear module 41 located on the loading and unloading platform 11 and part located in the working chamber 13. The clamping plate 42 is slidably set on the linear module 41. The linear module 41 can drive the clamping plate 42 to move, so that the clamping plate 42 enters or slides out of the working chamber 13, thereby performing the workpiece loading and unloading and measurement processes. This ensures that the operator will not come into contact with the parallel motion mechanism 2 and the measuring mechanism 3, thus ensuring safe use. At the same time, the working chamber 13 also provides a certain degree of protection.

[0030] like Figure 3 As shown, the measuring mechanism 3 includes a measuring head 31 and a probe 32. The measuring head 31 is connected to the parallel motion mechanism 2, and the probe 32 is connected to the lower end of the measuring head 31. The probe 32 is used to measure the size of the workpiece and compare it with the size data of the standard part, so as to detect the size of the workpiece. At the same time, it can also be linked with the CNC machine tool to adjust the machining data of the machine tool according to the size error with the standard part, so as to ensure the production quality of the workpiece.

[0031] It should be noted that the principle of the parallel motion mechanism 2 driving the measuring mechanism 3 to measure the workpiece is existing technology, and its specific structure will not be described in detail here.

[0032] In some embodiments, a lifting door 14 is provided on the working chamber 13. The lifting door 14 is located on the side wall of the working chamber 13 on the side of the pick-up and drop platform 11. The lifting door 14 can shield the working chamber 13 on the one hand, and raise or lower the lifting door 14 when picking up and dropping workpieces on the other hand, so as to ensure that the workpieces on the fixture plate 42 can smoothly enter and exit the working chamber 13 and form a stable testing environment for part measurement.

[0033] Specifically, Figure 4 and Figure 5 As shown, the work compartment 13 is provided with a support frame 15 on one side of the loading and unloading platform 11. The support frame 15 is provided with a slide groove 16 along the vertical direction. The lifting door 14 is slidably disposed in the slide groove 16, so that the lifting door 14 can move up and down in the slide groove 16.

[0034] Meanwhile, a sealing plate 17 is provided on the support frame 15, and the lifting door 14 is located inside the sealing plate 17. Through the cooperation of the sealing plate 17 and the lifting door 14, the working chamber 13 is protected.

[0035] like Figure 4 As shown, a display screen 18 is installed on the outer wall of the working chamber 13, which can display parameters and workpiece measurement results.

[0036] like Figure 4 As shown, the front side of the base 12 is provided with an inspection door 121, and the control module, power supply module and other components are installed in the base 12. The bottom of the base 12 is provided with casters 122 and support blocks 123, which facilitates the movement and fixation of the base 12.

[0037] Working principle:

[0038] In actual use, the fixture plate 42 is positioned in the area of ​​the pick-and-place platform 11. First, the standard part is placed on the fixture plate 42, then the lifting door 14 is raised, and the fixture plate 42 is transported to the work chamber 13 via the linear module 41. The probe 32 is moved by the parallel motion mechanism 2 to calibrate the standard part and generate calibration data. Then, the fixture plate 42 is reset and the standard part can be removed. During workpiece comparison measurement, the workpiece is placed on the fixture plate 42, then the lifting door 14 is raised, and the fixture plate 42 is transported to the work chamber 13 via the linear module 41. The probe 32 is moved by the parallel motion mechanism 2 to measure the workpiece. By comparing the acquired data with the calibration data, it is determined whether the workpiece is qualified.

[0039] This utility model provides a rapid relative measuring device for parts in machining production lines. It has a reasonable structure and is easy to operate. It can replace existing manual tools and custom measuring instruments to measure workpieces, which not only improves the convenience of use, but also significantly improves the accuracy of measurement, which is conducive to large-scale promotion.
