Technical Field

[0001] The utility model relates to the technical field of parts detection, in particular to a parts detection device for numerically controlled machine tools. Background Art

[0002] At present, CNC machine tools are automated machine tools equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. CNC machine tools have better solved the problems of complex, precise, small batch, and multi-variety parts processing. They are flexible and high-efficiency automated machine tools. The dimensions of the parts need to be detected after processing.

[0003] A Chinese utility model patent with announcement number CN211053261U discloses a detection device for CNC machine tool parts processing, including an operating table and a detection plate; a detection groove is opened in the middle of the upper surface of the operating table, the bottom end of the detection groove is connected to an adjustment groove, a push rod motor is arranged in the middle of the inner wall of the bottom end of the adjustment groove, and the motor shaft of the push rod motor is connected to a push rod.

[0004] Although the above-mentioned prior art can detect whether the length and width of the part are qualified through the scale lines set on the upper surface of the detection groove, and can detect whether the height of the part is qualified by sliding the detection plate through the guide rod passing through the guide groove to push the detection plate to the right side of the detection groove, it is unable to detect shaft parts. The existing product accuracy measurement of shaft parts after processing usually adopts manual vernier calipers and other detection instruments for measurement, which is relatively inefficient and prone to deviations due to human factors. Utility Model Content

[0005] In order to solve the technical problems that the existing product accuracy measurement of shaft parts after processing usually adopts manual vernier calipers and other detection instruments for measurement, which is inefficient and prone to deviations due to human factors, the utility model provides a parts detection device for CNC machine tools.

[0006] The utility model is implemented by the following technical scheme: a part detection device for a CNC machine tool, comprising a base and a part, the top of the base is fixedly connected to a part detection table, and cylinders are fixedly installed at both ends of the base, the output end of the cylinder is fixedly connected to a detection box, a detection mechanism is arranged inside the detection box for detecting the horizontality of the part, and a fixing mechanism is arranged inside the base for fixing the part during detection.

[0007] As a further improvement of the above scheme, the detection mechanism includes a threaded rod rotatably installed inside the detection box, a second servo motor is fixedly installed on one side of the detection box, and a slide groove is opened on the lower surface of the detection box, a detection block is meshed and sleeved on the surface of the threaded rod, a fixed rod is fixedly connected to the bottom of the detection block, and a detection component is fixedly connected to the bottom of the fixed rod.

[0008] Through the above technical solution, the threaded rod is driven to rotate by the rotation of the second servo motor, so that the detection block slides inside the slide groove. When the horizontality of the part deviates, the sliding of the detection block in the slide groove is blocked, thereby detecting that the part is unqualified. A clutch is arranged inside the second servo motor. When the second servo motor encounters resistance, the clutch will automatically open and the second servo motor will stop working immediately.

[0009] As a further improvement of the above scheme, the detection assembly includes an installation box fixedly connected to the bottom of the fixed rod, a first detection plate is fixedly connected to one side of the bottom of the installation box, and a second detection plate is slidably connected to the other side of the installation box, and a limit rod fixedly connected to the second detection plate is threadedly connected to one side of the installation box.

[0010] Through the above technical solution, the first detection plate and the second detection plate are located on both sides of the part, and the horizontality of the part can be detected when sliding. At the same time, the second detection plate is slidably set to detect shaft parts of different diameters, which is practical.

[0011] As a further improvement of the above solution, the output end of the second servo motor is transmission-connected to the threaded rod, and the fixed rod slides inside the sliding groove.

[0012] As a further improvement of the above solution, a controller is fixedly mounted on the front surface of the base, and a V-shaped groove for placing parts is opened on the top of the detection table.

[0013] Through the above technical solution, the V-groove can quickly position the parts, facilitate clamping, and improve work efficiency.

[0014] As a further improvement of the above scheme, the fixing mechanism includes a first servo motor fixedly installed inside the base and a bidirectional screw rod rotatably installed inside the base, the bidirectional screw rod is transmission connected to the output end of the first servo motor, and the surface of the bidirectional screw rod is meshed with a movable block, the top of the movable block is fixedly connected with a splint of a fixed part, and the splint slides on the upper surface of the base.

[0015] Through the above technical solution, the first servo motor rotates to drive the bidirectional screw to rotate, so that the clamping plate clamps the parts to maintain stability, thereby improving the accuracy of the detection result.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model makes the first detection plate tangent to one side of the part, then rotates the limit rod, so that the limit rod drives the second detection plate to be tangent to the other side of the part, and finally controls the second servo motor to work, so that the second servo motor drives the threaded rod to rotate when it rotates, so that the detection block slides inside the slide groove. When the detection block slides normally, the part is qualified. When the sliding of the detection block in the slide groove is blocked, it means that the part is unqualified. This design detects the horizontality of the part by clamping the part and sliding it quickly, which greatly improves the speed of part detection and speeds up work efficiency.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Example:

[0026] Please combine Figure 1 - Figure 4 A part detection device for a CNC machine tool in this embodiment includes a base 1 and a part 5. A detection table 3 for placing the part 5 is fixedly connected to the top of the base 1, and cylinders 10 are fixedly installed at both ends of the base 1. The output end of the cylinder 10 is fixedly connected to a detection box 11. A detection mechanism is arranged inside the detection box 11 for detecting the horizontality of the part 5. A fixing mechanism is arranged inside the base 1 for fixing the part 5 during detection.

[0027] Please combine Figure 1 and Figure 4 The detection mechanism includes a threaded rod 13 rotatably installed inside the detection box 11, a second servo motor 12 is fixedly installed on one side of the detection box 11, and a slide groove 15 is opened on the lower surface of the detection box 11, a detection block 14 is meshed and sleeved on the surface of the threaded rod 13, a fixing rod 16 is fixedly connected to the bottom of the detection block 14, and a detection component is fixedly connected to the bottom of the fixing rod 16.

[0028] The threaded rod 13 is driven to rotate by the second servo motor 12, so that the detection block 14 slides inside the slide groove 15. When the horizontality of the part 5 deviates, the sliding of the detection block 14 in the slide groove 15 is blocked, so that the part 5 is detected to be unqualified. A clutch is arranged inside the second servo motor 12. When the second servo motor 12 encounters resistance, the clutch will automatically open and the second servo motor 12 will stop working immediately.

[0029] Please combine Figure 4 The detection component includes an installation box 17 fixedly connected to the bottom of the fixing rod 16, a first detection plate 18 is fixedly connected to one side of the bottom of the installation box 17, and a second detection plate 19 is slidably connected to the other side of the installation box 17, and a limit rod 20 fixedly connected to the second detection plate 19 is threadedly connected to one side of the installation box 17.

[0030] By locating the first detection plate 18 and the second detection plate 19 on both sides of the part 5, the horizontality of the part 5 can be detected when sliding. At the same time, the second detection plate 19 is slidably arranged to detect shaft parts 5 of different diameters. It is practical and the detection component is replaceable.

[0031] Please combine Figure 3 The output end of the second servo motor 12 is transmission-connected to the threaded rod 13 , and the fixed rod 16 slides inside the slide groove 15 .

[0032] Please combine Figure 2 A controller 2 is fixedly mounted on the front surface of the base 1, and a V-shaped groove 4 for placing a part 5 is opened on the top of the detection table 3.

[0033] The V-shaped groove 4 can position the part 5 quickly, facilitate clamping, and improve work efficiency.

[0034] Please combine Figure 3 The fixing mechanism includes a first servo motor 6 fixedly installed inside the base 1 and a bidirectional screw rod 7 rotatably installed inside the base 1. The bidirectional screw rod 7 is transmission connected to the output end of the first servo motor 6, and a movable block 8 is meshed and sleeved on the surface of the bidirectional screw rod 7. The top of the movable block 8 is fixedly connected to a splint 9 of the fixed part 5, and the splint 9 slides on the upper surface of the base 1.

[0035] The first servo motor 6 rotates to drive the bidirectional screw rod 7 to rotate, so that the clamping plate 9 clamps the part 5 to maintain stability, thereby improving the accuracy of the detection result.

[0036] The implementation principle of a part detection device for a CNC machine tool in the embodiment of the present application is as follows: when working, the part 5 is placed in the V-groove 4, and the first servo motor 6 is controlled to work by the controller 2. When the first servo motor 6 rotates, it drives the bidirectional screw 7 to rotate, so that the movable block 8 drives the clamping plate 9 to slide, and the part 5 is clamped and fixed. Then the cylinder 10 is controlled to drive the detection box 11 to move down, so that the first detection plate 18 is tangent to one side of the part 5, and then the limit rod 20 is rotated so that the limit rod 20 drives the second detection plate 19 to be tangent to the other side of the part 5. Finally, the second servo motor 12 is controlled to work so that when the second servo motor 12 rotates, it drives the threaded rod 13 to rotate, so that the detection block 14 slides inside the slide groove 15. When the detection block 14 slides normally, the part 5 is qualified. When the detection block 14 is blocked from sliding in the slide groove 15, it means that the part 5 is unqualified.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
