Description

Technical Field

[0001] This invention relates to the field of long axis testing technology, and more specifically, to a testing mechanism for CNC machined parts. Background Technology

[0002] Long shafts machined by CNC machine tools need to be inspected to ensure that their end faces are flat. If the end faces of the long shafts are not flat, it will cause misalignment or uneven gaps when assembling with other components such as bearings and couplings, affecting the coaxiality of the transmission system.

[0003] When using a dial indicator to test the flatness of a long shaft end face, the dial indicator probe is pressed against the end face of the long shaft. Then, the long shaft is rotated evenly and slowly for one revolution. The dial indicator probe then touches the end face of the long shaft perpendicularly and observes the maximum and minimum dial indicator readings. The smaller the positive difference between the two, the flatter the end face of the long shaft. However, when testing the flatness of the end face of a long shaft with a keyway, due to the pressure between the probe and the end face of the long shaft, the long shaft rotates evenly and slowly, causing the keyway and the probe to overlap. At this point, the probe may get stuck in the keyway. Existing technology retracts the probe to avoid the keyway, then returns to the testing path and adjusts the pressure back to the original level. However, when the end face of the long shaft has multiple keyways, the probe needs to retract, avoid, and reposition itself multiple times for pressure adjustment. Furthermore, the probe may miss the edge of the keyway, affecting testing efficiency and results. Summary of the Invention

[0004] The present invention provides a testing mechanism for CNC machine tool parts, which aims to solve the following problem: When existing dial indicators test long shafts with flat keyways on the end face, their probes adopt a strategy of retracting to avoid the keyways. When the end face of the long shaft has multiple flat keyways, the probes repeatedly retract to avoid the keyways, which will miss the edge of the keyways, affecting the testing efficiency and test results.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a testing mechanism for CNC machine tool processed parts, comprising a base one, a base two, and a base three, wherein a robot arm is mounted on the outer side of the base one, and a dial indicator is mounted on the end effector of the robot arm; long shafts are mounted on the outer sides of the base two and the base three; a rotating mechanism is mounted on the outer side of the base three; and a filling mechanism is mounted on the outer side of the base two. The filling mechanism includes a U-shaped block, which is fixed to the outside of the base two. A square plate is fixedly connected to the outside of the U-shaped block. A moving part is installed on the side of the square plate near the base two. A control panel module is installed on the outside of the U-shaped block. A high-definition camera and a hydraulic rod two are set on the side of the moving part near the base two. An elastic part is fixedly connected to the output end of the hydraulic rod two. An adjustment part is installed on the outside of the elastic part. The high-definition camera works in conjunction with the rotating mechanism and moving parts, and controls the keyway of the long shaft to align with the adjustment part. The hydraulic rod carries the adjustment part into the keyway, and the elastic part allows the probe of the dial indicator to pass through the groove of the keyway.

[0006] In a preferred embodiment, the moving component includes a hydraulic rod, which is fixedly connected to the side of the U-shaped block near the base. The output end of the hydraulic rod is fixedly connected to a moving block, and the end of the moving block away from the high-definition camera is fixedly connected to a slider. A groove is provided on the side of the square plate near the high-definition camera.

[0007] In a preferred embodiment, both the groove and the slider are T-shaped, with the slider disposed inside the groove and slidably connected to the square plate.

[0008] In a preferred embodiment, the elastic component includes a cylindrical block, which is fixedly connected to the output end of the hydraulic rod 2. A groove is provided at the end of the cylindrical block away from the hydraulic rod 2. An electromagnet 1 and an elastic rope are fixedly connected inside the groove. An iron block is fixedly connected at the end of the elastic rope away from the hydraulic rod 2.

[0009] In a preferred embodiment, the adjusting component includes a square block, which is fixedly connected to the end of the iron block away from the electromagnet. A recessed hole is provided on the outer side of the square block, and a square block is slidably connected inside the recessed hole. Two square blocks are provided. A recessed hole is provided on the outer side of the square block, and an electromagnet is installed inside the recessed hole. A recessed hole is provided on the outer side of the square block.

[0010] In a preferred embodiment, a sliding groove is provided inside the recess, and a sliding block is fixedly connected to the outside of the square block. The sliding block is disposed inside the sliding groove, and the sliding block and the square block are slidably connected.

[0011] In a preferred embodiment, the rotating mechanism includes a U-block, which is fixedly connected to the outer side of the base three. A clamping component is installed on the outer side of the U-block. The clamping component includes a disc, which is disposed on the inner side of the U-block. A circular groove is formed at the end of the disc away from the U-block. An arc-shaped clamping block is disposed inside the circular groove. Two arc-shaped clamping blocks are provided. A telescopic rod and a spring are fixedly connected between the two arc-shaped clamping blocks and the disc, respectively. The telescopic rod is disposed on the inner side of the spring.

[0012] In a preferred embodiment, a rotating rod is fixedly connected to the end of the disk away from the circular groove, the end of the rotating rod away from the disk passes through the U-block, and a gear is fixedly connected to the end of the rotating rod away from the disk, with the rotating rod and the U-block being rotatably connected.

[0013] In a preferred embodiment, an electric component is installed on the outside of the U-block. The electric component includes a second gear, which is meshed with the outside of the first gear. A rotating shaft is fixedly connected to the side of the second gear near the U-block. A motor is provided on the side of the second gear near the U-block. The motor and the U-block are fixedly connected. The output end of the motor is fixedly connected to the end of the rotating shaft away from the second gear.

[0014] In a preferred embodiment, a shielding component is installed on the outside of the electric component. The shielding component includes a shielding block, which is disposed on the outside of the electric component. A square hole is opened on the outside of the shielding block, and an air vent plate is fixedly connected to the inside of the square hole.

[0015] The beneficial effects of this invention are as follows: This invention, through the arrangement of a rotating mechanism and an adjusting component, allows the dial indicator probe to easily become trapped inside the keyway of the long shaft due to the pressure exerted by the rotating mechanism on the long shaft. This requires the probe to be removed and the measurement repeated, necessitating a return to the original measurement route. Furthermore, the edge of the keyway is difficult to measure completely. However, the adjusting component pre-fills the keyway along the path the dial indicator probe will traverse, preventing the probe from becoming trapped and allowing direct measurement without repeated adjustment or movement during each measurement.

[0016] This invention, through the arrangement of a moving component and an elastic component in the filling mechanism, allows the control panel module to detect the keyway via a high-definition camera when filling a long-axis flat keyway. The moving component and hydraulic rod two are then activated to move the adjusting component into the keyway. Simultaneously, the adjusting structure guides the filling probe along its path. When the hydraulic rod two carries the adjusting component into the keyway, it pre-enters the path the probe will take. The elastic component ensures that as the adjusting component rotates with the long axis, the probe can properly complete the filling path. Attached Figure Description

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Refer to the instruction manual appendix Figures 1 to 5 A testing mechanism for CNC machine tool processed parts includes a base 1, a base 2, and a base 3. A robot arm 2 is installed on the outside of the base 1, and a dial indicator 3 is installed at the end of the robot arm 2. A long shaft 8 is installed on the outside of the base 2 and the base 3. A rotating mechanism 6 is installed on the outside of the base 3. A filling mechanism 7 is installed on the outside of the base 2. The filling mechanism 7 includes a U-shaped block 71, which is fixed to the outside of the base 2 4. A square plate 72 is fixedly connected to the outside of the U-shaped block 71. A moving part 73 is installed on the side of the square plate 72 near the base 2 4. A control panel module 75 is installed on the outside of the U-shaped block 71. A high-definition camera 74 and a hydraulic rod 2 76 are provided on the side of the moving part 73 near the base 2 4. An elastic part 77 is fixedly connected to the output end of the hydraulic rod 2 76. An adjustment part 78 is installed on the outside of the elastic part 77. The high-definition camera 74 works in conjunction with the rotating mechanism 6 and the moving part 73, and controls the keyway of the long shaft 8 to align with the adjusting part 78. The hydraulic rod 76 carries the adjusting part 78 into the keyway, and the elastic part 77 allows the probe of the dial indicator 3 to pass through the opening of the keyway.

[0029] It should be noted that, with Figure 1 For a direct view, base 2 4 is positioned to the left of base 1, base 3 5 is positioned to the left of base 2 4, robotic arm 2 is positioned above base 1, U-shaped block 71 is positioned above base 1, and square plate 72 is fixed to the right of U-shaped block 71.

[0030] In this embodiment, the specific implementation scenario is as follows: The operator uses the clamping component 62 of the rotating mechanism 6 to clamp and fix the long shaft 8 on the outside of the base 2 4 and the base 3 5. Then, the probe is pressed against the end face of the long shaft 8 that needs to be measured. Then, the electric component 63 is started to rotate the long shaft 8. With the cooperation of the control panel module 75, the high-definition camera 74, driven by the moving component 73 and the hydraulic rod 2 76, allows the adjusting component 78 to enter the groove that the probe of the dial indicator 3 needs to pass through. At the same time, the elastic component 77 ensures that the adjusting component 78 can also rotate with the long shaft 8, ensuring that the long shaft 8 follows the path filled by the adjusting component 78.

[0031] Refer to the instruction manual appendix Figure 6 The movable component 73 includes a hydraulic rod 731, which is fixedly connected to the side of the U-shaped block 71 near the base 1. The output end of the hydraulic rod 731 is fixedly connected to a movable block 732. The end of the movable block 732 away from the high-definition camera 74 is fixedly connected to a slider 733. A groove 734 is provided on the side of the square plate 72 near the high-definition camera 74.

[0032] It should be noted that, with Figure 1 To ensure a proper viewing angle, the high-definition camera 74 and the second hydraulic rod 76 are fixedly connected to the lower side of the moving block 732, facilitating movement of the high-definition camera 74 and the second hydraulic rod 76, and adjusting the route for the adjusting component 78 to enter the groove.

[0033] Refer to the instruction manual appendix Figure 6Both the slide groove 734 and the slider 733 are T-shaped. The slider 733 is located inside the slide groove 734 and is slidably connected to the square plate 72.

[0034] It should be noted that, with Figure 1 To improve the viewing angle, the T-shaped slider 733 and the groove 734 increase the stability of the moving block 732.

[0035] Refer to the instruction manual appendix Figure 7 The elastic component 77 includes a cylindrical block 771, which is fixedly connected to the output end of the hydraulic rod 76. A groove 772 is provided at the end of the cylindrical block 771 away from the hydraulic rod 76. An electromagnet 773 and an elastic rope 774 are fixedly connected inside the groove 772. An iron block 775 is fixedly connected at the end of the elastic rope 774 away from the hydraulic rod 76.

[0036] It should be noted that, in order to facilitate the adjustment component 78 filling the internal path of the groove, the probe can be returned to its original position while completing the path.

[0037] Refer to the instruction manual appendix Figures 8 to 9 The adjusting component 78 includes a square block 781, which is fixedly connected to the end of the iron block 775 away from the electromagnet 773. A recess 782 is provided on the outer side of the square block 781, and a square block 783 is slidably connected inside the recess 782. There are two square blocks 783. A second recess 784 is provided on the outer side of the square block 783, and an electromagnet 785 is installed inside the second recess 784. A third recess 788 is provided on the outer side of the square block 781.

[0038] It should be noted that, with Figure 1 For a frontal view, recess 1 782 is made on the front side of square block 781, recess 2 784 of front block 783 is made on the rear side, recess 2 784 of rear block 783 is made on the front side, and recess 3 788 is made on the left side of square block 781.

[0039] Refer to the instruction manual appendix Figure 8 The recessed hole 782 has a sliding groove 786 inside, and the square block 783 is fixedly connected to the outside of the sliding block 787. The sliding block 787 is set inside the sliding groove 786, and the sliding block 787 and the square block 781 are slidably connected.

[0040] It should be noted that, with Figure 1 To ensure a proper viewing angle, two sliding blocks 787 and two sliding grooves 786 are provided. The sliding grooves 786 are located on the upper and lower sides inside the recessed hole 782, and the sliding blocks 787 are located on the upper and lower sides of the square block 783. When the two square blocks 783 are moved to adjust the distance between them, it is to prevent the square block 783 from sliding out of the recessed hole 782.

[0041] Refer to the instruction manual appendix Figure 3 The rotating mechanism 6 includes a U-block 61, which is fixedly connected to the outside of the base 5. A clamping component 62 is installed on the outside of the U-block 61. The clamping component 62 includes a disc 621, which is located inside the U-block 61. A circular groove 622 is provided at the end of the disc 621 away from the U-block 61. An arc-shaped clamping block 623 is provided inside the circular groove 622. There are two arc-shaped clamping blocks 623. A telescopic rod 624 and a spring 625 are fixedly connected between the two arc-shaped clamping blocks 623 and the disc 621, respectively. The telescopic rod 624 is located inside the spring 625.

[0042] It should be noted that this makes it easier to clamp the long shaft 8.

[0043] Refer to the instruction manual appendix Figure 2 A rotating rod 626 is fixedly connected to the end of the disc 621 away from the circular groove 622. The end of the rotating rod 626 away from the disc 621 passes through the U-block 61. A gear 627 is fixedly connected to the end of the rotating rod 626 away from the disc 621. The rotating rod 626 and the U-block 61 are rotatably connected.

[0044] It should be noted that this facilitates the rotation of the disc 621, which in turn causes the long shaft 8 to rotate.

[0045] Refer to the instruction manual appendix Figure 4 An electric component 63 is installed on the outside of U-block 61. The electric component 63 includes a second gear 633, which is meshed with the outside of the first gear 627. A rotating shaft 632 is fixedly connected to the side of the second gear 633 near U-block 61. A motor 631 is provided on the side of the second gear 633 near U-block 61. The motor 631 and U-block 61 are fixedly connected. The output end of the motor 631 is fixedly connected to the end of the rotating shaft 632 away from the second gear 633.

[0046] It should be noted that the motor 631 is used to drive the clamping component 62 and the long shaft 8 to rotate.

[0047] Refer to the instruction manual appendix Figure 4 A shielding component 64 is installed on the outside of the electric component 63. The shielding component 64 includes a shielding block 641. The shielding block 641 is disposed on the outside of the electric component 63. A square hole 642 is opened on the outside of the shielding block 641. An air vent plate 643 is fixedly connected to the inside of the square hole 642.

[0048] It should be noted that when the motor 631 is carrying the clamping component 62 and the long shaft 8, the motor 631 will generate heat during operation. The air vent plate 643 of the shielding block 641 facilitates heat dissipation of the motor 631 during operation.

[0049] In this embodiment, the specific implementation scenario is as follows: First, when the operator uses dial indicator 3 to measure the flatness of the end face of the long shaft 8, the long shaft 8 is placed outside the base 2 4 and base 3 5. Then, one end of the long shaft 8 on base 3 5 is inserted into the circular groove 622 of the disc 621. Before this, the operator presses one side of the arc-shaped clamp 623 by hand, causing the arc-shaped clamp 623 to compress the spring 625 and move the telescopic rod 624. Then, one end of the long shaft 8 inside the circular groove 622 is placed into the outside of the other side of the arc-shaped clamp 623. Then, the compressed and moved arc-shaped clamp 623 is released, allowing the arc-shaped clamps 623 on both sides to hold the long shaft 8 and fix it in place. At the same time, the robotic arm 2 on the upper side of base 1 is activated, moving the dial indicator 3 and adjusting its angle. Then, the probe of the dial indicator 3 contacts the end face of the long shaft 8 that needs to be tested and applies pressure to the probe. The force is applied to the outer side of the end face of the long shaft 8. Then, the motor 631 is started. The motor 631 rotates the rotating shaft 632, which in turn rotates the gear 2 633. The gear 2 633 rotates the gear 1 627, which in turn rotates the rotating rod 626 and the disc 621. The disc 621 rotates the long shaft 8 evenly and slowly in one direction. At this time, the high-definition camera 74 detects the keyway near the rotating long end face. Once it is detected that the probe of the dial indicator 3 is about to pass through the keyway, the control panel module 75 controls the motor 631 to rotate the long shaft 8, so that the square block 781 of the vertical adjustment component 78 is at the center of the keyway. Then, the hydraulic rod 1 731 is started to move the moving block 732. The moving block 732 moves the slider 733 as it moves, until the right side of the square block 781 is parallel to the end face of the long shaft 8 to be tested.Then, stop the movement of the hydraulic rod, and start the second hydraulic rod 76 to move the elastic component 77 and the adjusting component 78. According to the path of the probe in the groove 772, select the square block 781 to move to this point. At this time, energize the second electromagnet 785 in the adjusting component 78, and energize the two electromagnets 785 with opposite currents, so that the opposite surfaces of the two electromagnets 785 repel each other due to the same force. At the same time, use the magnitude of the current to adjust the sliding position of the square block 783 until the square block 783 is sprayed into the position of the long shaft 8 inside the keyway. Maintain the current magnitude at this time and let the probe continue to pass through the groove. At this time, the probe passes the right side of the square blocks 783 and 781. The height between the square blocks 781 and 783 is very small, allowing the probe to pass through easily. The data of the dial indicator 3 as the probe passes through the adjusting structure does not need to be recorded. After the adjusting structure is fixed in the groove, de-energize the first electromagnet 773 to separate the iron block 775 from the cylindrical block 771. The time axis 8 rotates, carrying the adjustment structure and iron block 775. Iron block 775 rotates along the elastic rope 774. After the probe has completed the path filled by the adjustment structure inside the groove, one of the electromagnets 785 in the adjustment structure is energized with an electric current in the opposite direction. This causes the two electromagnets 785 to attract each other, detaching the square block 781 from the groove. At this point, the adjustment structure resets under the action of the elastic rope 774, returning to the cylindrical block 77 with iron block 775. On the lower side of 1, electromagnet 773 is energized to attract iron block 775. Then, with the assistance of control panel module 75, high-definition camera 74 and manual assistance, the next flat keyway is filled until the long axis 8 has completed a route measurement. Then, the position and direction of dial indicator 3 probe are changed, and the flatness of the end face of long axis 8 is tested in this way. The data passing through the groove by dial indicator 3 probe is excluded. The maximum and minimum data of dial indicator 3 are recorded. The smaller the positive difference between the two, the higher the flatness.

[0050] Working principle: 1. When testing the flatness of the end face of the long shaft 8, place the non-test end on the outside of the base 3 5 and the other end on the outside of the base 2 4. Then, clamp the non-test end with the clamping component 62. After that, start the robotic arm and adjust the position of the dial indicator 3 so that the probe is pressed on the end face of the long shaft 8 to be tested.

[0051] Second, under the control of the high-definition camera 74 and the control screen module 75 of the filling mechanism 7, the adjustment component 78 is slid into the keyway in advance, and then the keyway is filled with the correct path so that the probe can pass through directly.

[0052] Third, the adjusting component 78 then rotates with the long shaft 8, de-energizing the electromagnet 773 of the elastic component 77, allowing the adjusting component 78 to rotate with the iron block 775. After the probe has passed through the groove filled by the adjusting component 78, the adjusting component 78 returns to its original position with the iron block 775.

[0053] Fourth, follow the previous steps to fill the long shaft 8 keyway, record the data in dial indicator 3, remove the data in dial indicator 3 after the probe passes through the groove, and then record the largest and smallest data in dial indicator 3. At this time, the smaller the positive difference between the two, the higher the flatness.

[0054] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
