Description

Technical Field

[0001] The present application relates to the technical field of dimension detection, and in particular to an automatic flatness dimension detection device. Background Art

[0002] Flatness is a type of geometric tolerance. It compares the actual surface to be measured with the ideal plane. The line distance between the two is the flatness error value. It is mostly used to measure the surface of workpieces manufactured on automated and semi-automated production lines to achieve rapid detection of product quality.

[0003] For example, the patent with publication number CN113375539A specifically discloses a CNC turret detection device, which installs the CNC turret to be detected on the mounting seat, adjusts the universal connecting arm so that the micrometer is set horizontally, and then moves the slide so that the micrometer can move against the side wall of a first clamping position on the tool holder plate. If the side wall of the first clamping position is not in a horizontal state, the reading of the micrometer will change. Once the reading of the micrometer exceeds the limit value, the first clamping position is non-compliant. By rotating the tool holder plate, all the first clamping positions are detected, and then the slide is moved to the Y-axis slide rail, and the universal connecting arm is readjusted so that the micrometer can detect the second clamping position.

[0004] However, after the test of the above patent, when the tool holder disc is rotated, in some complex processing tasks, it may be necessary to use blades of different sizes to adapt to different processing depths and widths, which will cause the tool positions on the tool holder disc to have different sizes, resulting in uneven weight distribution on the tool positions on the tool holder disc. Therefore, when the motor rotates, the motor may be affected by the load change, resulting in a slight deviation in the rotation angle. Although the control system such as PLC can accurately control the rotation angle of the motor, the load change may cause the control system to produce errors when adjusting the motor output in real time, thereby affecting the accuracy of the rotation angle, causing the tool position on the tool disc to be unable to be guaranteed to be horizontal, thereby affecting the detection of the tool position on the tool disc;

[0005] Therefore, it is necessary to provide a flatness dimension automatic detection device to solve the above problems.

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0040] Embodiment 1: This embodiment specifically describes the basic structure and working principle of the flatness dimension automatic detection device, specifically:

[0041] like Figure 9-10 As shown, the flatness dimension automatic detection device disclosed in the present application is mainly used for detecting the tool disk 5 of the CNC tool turret. The tool disk 5 has multiple groups of tool positions, and each group of tool positions has three detection directions, specifically:

[0042] like Fig.10 As shown, the cutter head 5 is divided from left to right into a first platform 51 to be inspected, a second platform 52 perpendicular to the first platform 51, and a third platform 53 perpendicular to the second platform 52;

[0043] like Figure 1 As shown, the present application provides an automatic detection device for the flatness dimensions of the above-mentioned cutter disc 5 in three directions, including a test bench 1, and a detection component 2 is arranged on the test bench 1, and the detection component 2 is used to detect the flatness of the cutter disc 5 to be detected;

[0044] The detection assembly 2 includes a first drive module 21 fixedly mounted on both sides of the upper end of the test bench 1. The first drive module 21 uses an existing ball screw and a linear guide as a transmission mechanism, and a drive device as a power source. The drive device can be a motor or a hydraulic motor. The specific structure and working principle are prior art and will not be described in detail here. For the convenience of explanation, the moving direction of the first drive module 21 is defined as the Z axis.

[0045] A beam 22 is commonly provided at the output ends of the two groups of first driving modules 21, and driven by the first driving modules 21, the driving beam 22 can move in the Z-axis direction. Meanwhile, a second driving module 23 is fixedly installed on one side of the beam 22, so that when the beam 22 moves, the second driving module 23 is synchronously driven to move, and the moving direction of the second driving module 23 is perpendicular to the moving direction of the first driving module 21. For the convenience of description, the moving direction of the second driving module 23 is defined as the X-axis.

[0046] At the same time, a third driving module 24 is vertically arranged on the output end of the second driving module 23, so that the third driving module 24 can be driven to move in the X-axis direction under the drive of the second driving module 23, and the moving direction of the third driving module 24 is the vertical direction. For the convenience of description, the moving direction of the third driving module 24 is defined as the Y-axis;

[0047] It should be noted that the structural components and driving methods of the second driving module 23 and the third driving module 24 are the same as those of the first driving module 21, and only the positions and sizes are slightly different, so the structures and principles of the second driving module 23 and the third driving module 24 are not described in detail here;

[0048] It can be understood that the first driving module 21, the second driving module 23 and the third driving module 24 constitute a traditional three-axis driving system. Of course, other methods can also be used to constitute the above three-axis driving system, which is not limited in this embodiment;

[0049] like Figure 1-Figure 2 As shown, a mounting seat 25 is fixedly mounted on the output end of the third driving module 24, a support frame 26 is fixedly mounted on the mounting seat 25, and a rotating cylinder 27 is fixedly mounted on the bottom of the support frame 26, and the output end of the rotating cylinder 27 is suitable for rotating in the horizontal direction. For the convenience of description, the rotating direction of the rotating cylinder 27 is defined as the A axis;

[0050] At the same time, a connecting frame 28 is fixedly installed at the output end of the rotating cylinder 27, and a servo motor 29 is fixedly installed on one side of the connecting frame 28. The output end of the servo motor 29 is suitable for rotating in the vertical direction. For the convenience of description, the rotation direction of the servo motor 29 is defined as the B axis. At the same time, a micrometer 210 is fixedly installed at the output end of the servo motor 29;

[0051] It should be noted that the first drive module 21, the second drive module 23, the third drive module 24, the rotary cylinder 27 and the servo motor 29 are all controlled by the PLC system, and then the micrometer 210 can be driven to move in the five-axis direction under the control of the PLC system to improve the detection flexibility and perform flatness detection on the cutter head 5. At the same time, the micrometer 210 is connected to the PLC system for communication so as to upload the detection data in real time;

[0052] Meanwhile, a clamping assembly 3 is provided on the test bench 1, and the clamping assembly 3 is used to clamp the cutter disc 5;

[0053] like Figure 4-Figure 5 As shown, the clamping assembly 3 includes a support plate 31 fixedly mounted on the test bench 1, and a stepper motor 32 is fixedly mounted on one side of the support plate 31, and a fixed cylinder 33 is fixedly mounted on the output end of the stepper motor 32, and the fixed cylinder 33 is suitable for rotating under the drive of the stepper motor 32;

[0054] The fixing cylinder 33 has a disc portion suitable for fitting with one side of the cutter disc 5, and an elastic chuck 35 is provided on one side of the disc portion. The elastic chuck 35 is used to place the cutter disc 5, and the elastic chuck 35 is composed of multiple groups of elastic sheets, and a round seat 34 is provided on one side of the multiple groups of elastic sheets. The diameter of the round seat 34 is larger than the elastic sheets, and an end head is slidably provided inside the round seat 34, so that the end head can be driven to extend or contract inside the round seat 34 under the action of external force, and when extending, the multiple groups of elastic sheets can be tightened outward to fix the cutter disc 5;

[0055] Continue to refer Figure 5 A cylindrical portion is provided on the other side of the disc portion, an electric cylinder (not shown in the figure) is fixedly installed inside the cylindrical portion, and the output end of the electric cylinder is fixedly connected to the end head, so that the elastic chuck 35 can be extended or retracted under the drive of the electric cylinder, and when extended, the elastic chuck 35 is supported by the end head, so that the cutter disc 5 can be tightened and fixed;

[0056] It should be noted that the connection between the end and the output end of the electric cylinder has a tapered surface so that the end can be retracted more smoothly;

[0057] To sum up, when inspecting the cutter disc 5, the cutter disc 5 is placed on the elastic chuck 35 so that it fits with one side of the disc portion on the fixed cylinder 33, the electric cylinder is started to drive the end head to contract, and then the multiple groups of elastic sheets on the elastic chuck 35 are tightened outward to fix the cutter disc 5, and then the inspection component 2 is started, and the micrometer is adjusted to the cutter disc 5 through the first drive module 21, the second drive module 23, and the third drive module 24, so that the contact of the micrometer is attached to the plane of the first platform 51, and then the second drive module 23 is started to drive the micrometer to move along the X-axis direction. In this process, the other moving modules are fixed, and then the flatness of the cutter position plane in the first moving direction is inspected, and its inspection data is uploaded in real time;

[0058] When inspecting the second platform 52, first move the micrometer away from the cutter head 5, then start the rotary cylinder 27 to drive the micrometer to rotate 90 degrees along the A axis, adjust the contact of the micrometer to fit the plane of the second platform 52, then start the first drive module 21 to drive the micrometer to move along the Z axis, so as to inspect the flatness of the cutter position of the second platform 52;

[0059] When inspecting the third platform 53, first move the micrometer away from the tool disc 5, adjust the angle of the micrometer to the same angle as that of the second platform 52, then start the servo motor 29 to drive the micrometer to rotate ninety degrees along the B axis, fit the contact of the micrometer with the plane of the third platform 53, then start the third drive module 24 to drive the micrometer to move along the Y axis, and then inspect the flatness of the third downward tool position.

[0060] Embodiment 2:

[0061] Although the above process can realize the flatness detection of the tool positions of the cutter disc 5, in order to ensure the quality of the detection of the cutter disc 5, it is necessary to detect multiple groups of tool positions in sequence, so the stepper motor 32 is required to drive the cutter disc 5 to rotate. When the stepper motor 32 drives the cutter disc 5 to rotate, it may be affected by the load, resulting in a slight deviation in the rotation angle, affecting the accuracy of the rotation angle, so that the cutter disc 5 cannot reach the preset position, thereby affecting the detection of the tool positions of the cutter disc 5.

[0062] In order to solve this problem, a straightening assembly 4 is provided on the test bench 1, and the straightening assembly 4 is used for fine adjustment of the position of the cutter head 5 after rotation;

[0063] like Figure 1 and Figure 3 As shown, the straightening assembly 4 includes two sets of slide rails 43 fixedly mounted on the test bench 1, the two sets of slide rails 43 are arranged opposite to each other, and connecting blocks 44 are slidably arranged on the two sets of slide rails 43, and two sets of hydraulic cylinders 41 are fixedly mounted on the test bench 1, and the two sets of hydraulic cylinders 41 are arranged opposite to each other, and a push rod 42 is fixedly mounted on the output end of the hydraulic cylinder 41, and the push rod 42 is connected to one end of the connecting block 44, and then driven by the hydraulic cylinder 41, the connecting block 44 can move on the slide rail 43 group;

[0064] At the same time, a mounting box 45 is fixedly installed at one end of the connecting block 44 away from the slide rail 43, so that when the connecting block 44 moves, the mounting box 45 is synchronously driven to move. A track 411 is fixedly installed inside the mounting box 45 (refer to Figure 8 ), and slideably arranged on the track 411 with the insert block 47;

[0065] It should be noted that the installation box 45 is parallel to the horizontal plane on the first platform 51 of the cutter head 5 in a horizontal state, and thus when the installation box 45 moves, it can extend into the upper end of the first platform 51;

[0066] It should be noted that when the installation box 45 extends into the upper end of the first platform 51, the output end of the electric cylinder can be controlled to retract, so that the end head withdraws from the elastic clamp 35, and then the elastic clamp 35 loosens the clamping of the cutter disc 5. At this time, since the side of the installation box 45 can be supported on the cutter disc 5, the cutter disc 5 will not fall, and the cutter disc 5 can be rotated on the elastic clamp 35, so as to facilitate the subsequent horizontal alignment operation of the cutter disc 5.

[0067] In this embodiment, a corresponding sensor may be provided to collect the position of the installation box 45, such as a position sensor, so as to determine the position of the installation box 45 and further control the electric cylinder.

[0068] like Figure 6 and Figure 8 As shown, one end of the plug block 47 has an elliptical portion, the center of the elliptical portion is at the same height as the axis of the elastic clamp 35, and a slot 471 is provided inside the installation box 45, so that when the installation box 45 moves, the plug block 47 is synchronously driven to move until the elliptical portion of the plug block 47 abuts against the elastic clamp 35. As the installation box 45 continues to move, the plug block 47 is restricted by the elastic clamp 35 to move on the track 411 to the inside of the slot 471;

[0069] Continue to refer Figure 8 Two groups of inclined grooves 482 are provided through the insert block 47. The two groups of inclined grooves 482 are arranged opposite to each other, and the distance between the two groups of inclined grooves 482 gradually increases along the direction close to the elliptical portion. For the convenience of description, the ends of the two groups of inclined grooves 482 that are close to each other are defined as the initial ends, and the ends that are away from each other are defined as the terminal ends;

[0070] A slide bar 483 is slidably arranged inside the inclined groove 482, and a push rod 48 is fixedly installed at one end of the slide bar 483. The push rod 48 passes through the top of the installation box 45 and a part of it is exposed. Two sets of shaft sleeves 49 are fixedly installed on the installation box 45, and the parts of the two sets of push rods 48 exposed from the installation box 45 are located in the two sets of shaft sleeves 49.

[0071] It should be noted that in the initial state, the two sets of slide bars 483 are both located at the initial end. When the insert block 47 moves toward the inside of the slot 471, the inclined slot 482 is synchronously driven to move, thereby driving the two sets of slide bars 483 to move from the initial end to the terminal end, so that the two sets of ejector rods 48 gradually extend out of the installation box 45.

[0072] At this time, the two sets of slide bars 483 move away from each other, thereby driving the two sets of push rods 48 to move away from each other, so as to extend out of the installation box 45, and then the two sets of push rods 48 are respectively pressed against the first platform 51 and the top surface opposite to the first platform 51, so as to perform a horizontal alignment operation on the cutter head 5, and under the restriction of the shaft sleeve 49, the moving direction thereof is restricted;

[0073] Continue to refer Figure 8 The push rod 48 has a convex plate (not shown in the figure), and a compression spring 481 is provided between the convex plate and the inner wall of the slot 471. At the same time, two sets of return springs 410 are provided between one side of the insert block 47 and the side wall of the slot 471. When the push rod 48 moves, the compression spring 481 is compressed due to the action of the convex plate, and the return spring 410 is compressed by the insert block 47.

[0074] When the hydraulic cylinder 41 is reset, the mounting box 45 is reset through the connecting block 44. At this time, under the action of the reset spring 410, the plug block 47 continues to resist the elastic clamp 35. Due to the continuous movement of the mounting box 45, the sliding rod 483 is synchronously moved toward the initial end in the inclined groove 482 through the push rod 48, so as to drive the two sets of push rods 48 to gradually reset. In this process, the reset spring 410 will gradually reset until the reset is completed. The mounting box 45 drives the plug block 47 to separate from the elastic clamp 35 and reset.

[0075] In summary, when it is necessary to measure multiple tool positions of the cutter disc 5 in sequence, it is necessary to calibrate the tool position to be measured first. At this time, the stepper motor 32 drives the clamping assembly 3 to rotate a certain angle. During the rotation of the stepper motor 32, a slight deviation in the rotation angle may occur due to a change in the load. At this time, the cutter disc 5 needs to be horizontally aligned and corrected. At this time, the two groups of hydraulic cylinders 41 are started, and the two groups of mounting boxes 45 are driven by the connecting block 44 to extend into the first platform 51 on both sides of the cutter disc 5.

[0076] Then, the clamping assembly 3 is controlled to slightly loosen the cutter disc 5 so that it can rotate on the elastic clamp 35. When the installation box 45 drives the plug block 47 to abut against the elastic clamp 35, the plug block 47 moves toward the inside of the slot 471 with the continuous movement of the installation box 45 and the restriction of the elastic clamp 35. At the same time, the installation box 45 synchronously drives the push rod 48 to move. At this time, the slide bar 483 will move from the initial end to the terminal end in the inclined groove 482 to drive the two groups of push rods 48 on both sides to synchronously extend out of the installation box 45 and abut against the first platform 51 and the top surface opposite to the first platform 51. As the push rod 48 continues to extend, it abuts against the four points on both sides, thereby adjusting the cutter disc 5 horizontally. After the adjustment is completed, the clamping assembly 3 is controlled to clamp the cutter disc 5.

[0077] Embodiment three:

[0078] Although the above process can realize the horizontal adjustment of the cutter disc 5, when the clamping assembly 3 slightly loosens the clamping of the cutter disc 5, the cutter disc 5 may move downward due to gravity, causing part of the cutter disc 5 to "lie" on the elastic clamp 35, thereby affecting the adjustment effect when performing horizontal adjustment;

[0079] In order to solve this problem, an adjustment portion is provided on the mounting box 45, and the adjustment portion is used to make the cutter head 5 in a vertical state;

[0080] like Figure 6-Figure 7 As shown, the adjustment part includes two groups of guide rods 462 fixedly installed on the side of the installation box 45 close to the first platform 51, and a pad 461 is slidably arranged on the guide rod 462, and a screw rod 464 is rotatably installed on the installation box 45, one end of the screw rod 464 is fixedly sleeved with a gear 463, the gear 463 is located inside the slot 471, and the pad 461 is transmission-installed on the screw rod 464, and then driven by an external force, the screw rod 464 is driven to rotate through the gear 463, thereby driving the pad 461 to move on the axis of the screw rod 464, and under the action of the guide rod 462, its moving direction is limited;

[0081] At the same time, an inclined slider 46 is fixedly installed on one side of the pad 461. The inclined slider 46 has a slider end surface 401, and the first platform 51 has a platform end surface 511. The slider end surface 401 and the platform end surface 511 are in the same horizontal plane.

[0082] When the installation box 45 moves toward the first platform 51 on the slide rail 43, the inclined slider 46 is synchronously driven to move, and then when the installation box 45 extends into the tool position of the first platform 51, the slider end surface 401 of the inclined slider 46 gradually abuts against the platform end surface 511 of the first platform 51. At this time, the cutter disc 5 is restricted by the inclined slider 46 and the disc portion of the fixed cylinder 33 to keep it in a vertical state without deviation, and then the clamping assembly 3 is controlled to slightly loosen the cutter disc 5.

[0083] A cavity (not shown in the figure) is provided inside the inclined slider 46, and parts of the screw rod 464 and the guide rod 462 are both located in the cavity, so that when the pad 461 moves, the inclined slider 46 is synchronously driven to move, and under the restriction of the cavity, the moving distance of the pad 461 is limited;

[0084] At the same time, two sets of connecting plates 466 are fixedly installed on one side of the plug block 47, and a rack 465 is fixedly installed on one end of the connecting plate 466. The rack 465 and the gear 463 can be meshed, and then when the plug block 47 moves, the rack 465 meshes with the gear 463, so that the gear 463 rotates;

[0085] In summary, when the installation box 45 extends into the first platform 51, the inclined slider 46 is synchronously driven to abut against the side wall of the cutter disc 5. At this time, under the restriction of the inclined slider 46 and the disc portion of the fixed cylinder 33, the cutter disc 5 remains in a vertical state until the insert block 47 moves into the slot 471, and the rack 465 is synchronously driven to mesh with the gear 463, thereby driving the screw rod 464 to rotate, and driving the inclined slider 46 to move through the pad 461, so that it is separated from the side wall of the cutter position. It should be noted that when the rack 465 is meshed with the gear 463, the push rod 48 has already contacted the inner wall of the cutter position;

[0086] During the subsequent resetting process of the insert block 47, the inclined slider 46 is reset by the restoring force of the reset spring 410 to facilitate the next calibration. At this time, because the resistance to the reset of the inclined slider 46 is small, the reset spring 410 can drive the rack 465 to drive the gear 463 to rotate, thereby achieving the effect of resetting the inclined slider 46.

[0087] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
