Description

Technical Field

[0001] The present invention relates to the technical field of workpiece quality inspection, and more particularly, to a workpiece processing quality inspection mechanism and a high-quality processing automatic machine tool. Background Art

[0002] In workpiece processing, for the inspection of the processing quality of machined holes, the inspection is usually completed by measuring the hole diameter. In actual operation, in order to improve the measurement accuracy, multi-point measurement is usually adopted to reduce the measurement error. However, this measurement method has obvious loopholes. It is impossible to continuously inspect the machined holes, the coverage rate of the inspection position on the inner surface of the machined hole is low, it is impossible to comprehensively inspect the machined holes, and the reliability of the inspection results is relatively low.

[0003] In view of this, the present application is specifically proposed. Summary of the Invention

[0004] The first object of the present invention is to provide a workpiece processing quality inspection mechanism, which can effectively improve the comprehensiveness of the inspection of the inner surface of the machined hole, overcomes the limitations of the traditional inspection method, and can more reasonably reflect the actual processing quality of the machined hole, which has positive significance for further improving the processing accuracy.

[0005] The second object of the present invention is to provide a high-quality processing automatic machine tool, which can effectively improve the comprehensiveness of the inspection of the inner surface of the machined hole, overcomes the limitations of the traditional inspection method, and can more reasonably evaluate the actual processing quality of the machined hole during the processing process, thereby further improving the processing accuracy of the machined hole.

[0006] The embodiments of the present invention are implemented as follows:

[0007] A workpiece processing quality inspection mechanism includes: a reference shaft, a test column, a positioning seat, and a processor.

[0008] The number of test columns is greater than or equal to 3, and the test columns are all arranged parallel to the reference shaft. Along the circumferential direction of the reference shaft, the test columns are evenly spaced.

[0009] Each test column is correspondingly provided with a positioning seat, and the positioning seat is arranged along the radial direction of the reference shaft and connected to the reference shaft.

[0010] A moving member is provided at one end of the positioning seat away from the reference shaft. Along the axial direction of the positioning seat, the moving member is slidably engaged with the positioning seat. The moving member is provided with a spring-back mechanism, and the spring-back mechanism is used to drive the moving member to move towards the end of the positioning seat away from the reference shaft. The test column is installed on the moving member.

[0011] Any one of the test columns is configured as a light source column, and the remaining test columns are configured as reflection columns. The plane where the central axes of the test column and the reference shaft are located is used as a reference plane.

[0012] The light source column is provided with a first light source and a beam receiving module. The first light source is arranged on one side facing the reference surface, and the beam receiving module is arranged on the other side facing the reference surface. The reflection column is provided with a reflecting member.

[0013] During detection, the reference axis is used to extend into the processing hole of the workpiece to be measured and is used to be coaxially arranged with the processing hole. The test column is used to abut against the hole wall of the processing hole so that the characteristic light beam emitted by the first light source can be projected onto the beam sensing part of the beam receiving module after being reflected by the reflecting members of each reflection column in sequence.

[0014] The beam sensing part is electrically connected to the processor to send beam detection data to the processor during the rotation of the reference axis. The processor is used to judge whether the processing hole is qualified according to the beam detection data.

[0015] Furthermore, the test column includes a core body and a rotating sleeve. The rotating sleeve is cylindrical, and the rotating sleeve is rotatably sleeved on the core body. The test column cooperates with the moving part through the core body. The rotating sleeve is made of a light-transmitting material.

[0017] In the reflection column, the reflecting member is arranged on the core body. The reflecting surface of the reflecting member is perpendicular to the reference surface, and the central axis of the reflection column is located in the plane corresponding to the reflecting surface of the reflecting member.

[0018] When the processing hole is a standard round hole, when the characteristic light beam is projected onto each reflection column in sequence, the characteristic light beam intersects with the central axis of the corresponding reflection column.

[0027] The moving member is provided with a fitting through hole, and the aperture of the fitting through hole is adapted to the outer diameter of the second fitting column, and the second fitting column is fitted in the fitting through hole.

[0028] When the test column is parallel to the reference axis, the first fitting columns at both ends of the core body are in contact with the moving member.

[0029] Further, the positioning seat further includes: a connecting arm. The connecting arm is fixedly connected between two groups of rod bodies of the same positioning seat.

[0030] The rod body also has a receiving cavity extending along its axial direction. The receiving cavity is located on the side of the chute close to the reference axis, and the receiving cavity extends to communicate with the cavity of the chute.

[0031] A sliding block is fixedly connected to the side of the moving member close to the receiving cavity. The sliding block extends into the receiving cavity and is slidably fitted in the receiving cavity, and a sliding seal is provided between the sliding block and the receiving cavity.

The first pipe body and the third pipe body are both arranged along the length direction of the connecting arm, and the second pipe body is arranged along the width direction of the connecting arm.

[0034] The first pipe body is communicated with the receiving cavity. A detection rod is slidably fitted in the third pipe body, and a sliding seal is provided between the detection rod and the third pipe body. One end of the detection rod close to the second pipe body is fixedly connected with a rebounding rod. The outer diameter of the rebounding rod is smaller than the inner diameter of the third pipe body. The rebounding rod extends along the axial direction of the third pipe body and penetrates outside the third pipe body.

The elastic member is provided with a pressure detection mechanism for detecting its elastic force, and the pressure detection mechanism is electrically connected to the processor.

[0036] A liquid medium is contained in the receiving cavity, the first pipe body, the second pipe body and the third pipe body.

[0037] The processor is used to judge whether the processed hole is qualified according to the detection data of the pressure detection mechanism.

[0038] Further, the flow area in the third pipe body is smaller than the flow area in the receiving cavity.

[0070] Embodiment 1

[0071] In order to overcome the deficiencies existing in the prior art, please refer to Figures 1-7 , this embodiment provides a workpiece processing quality detection mechanism, which includes: a reference shaft 100, a test column 200, a positioning seat 400, and a processor (not shown in the figure).

[0072] During actual use, the reference shaft 100 can be installed on a base (not shown in the figure), and the base can be position-controlled by a position adjustment mechanism (not shown in the figure, and the position adjustment mechanism includes but is not limited to: a robotic arm) to realize the adjustment of the position of the reference shaft 100. And it is not limited to this.

[0073] The number of test columns 200 is greater than or equal to 3, and the specific number can be flexibly set according to actual needs. In this embodiment, 3 test columns 200 are taken as an example for illustration, which does not limit the technical solution of the application.

[0074] The test columns 200 are all arranged parallel to the reference shaft 100, and the test columns 200 are arranged at intervals from the reference shaft 100. Along the circumferential direction of the reference shaft 100, the 3 test columns 200 are evenly spaced.

[0075] Each test column 200 is correspondingly provided with a positioning seat 400, the positioning seat 400 is arranged along the radial direction of the reference shaft 100, and one end of the positioning seat 400 is connected to the reference shaft 100.

[0076] A moving member 500 is arranged at the end of the positioning seat 400 far from the reference shaft 100. Along the axial direction of the positioning seat 400, the moving member 500 is slidably matched with the positioning seat 400. The moving member 500 is provided with a spring-back mechanism, and the spring-back mechanism is used to drive the moving member 500 to move towards the end of the positioning seat 400 far from the reference shaft 100, that is, the spring-back mechanism is used to continuously provide a driving force for the moving seat to move towards the end of the positioning seat 400 far from the reference shaft 100. In the natural state, under the action of the spring-back mechanism, the moving member 500 will move to the end of the positioning seat 400 far from the reference shaft 100.

[0077] The test column 200 is installed on the moving member 500.

[0078] Any one of all the test columns 200 is configured as a light source column, and the remaining test columns 200 are configured as reflection columns. For the convenience of structural description, the plane where the central axes of both the test column 200 and the reference axis 100 are located is used as the reference plane 210.

[0079] In the light source column, a first light source 310 and a light beam receiving module 320 are provided. The first light source 310 is used to emit a characteristic light beam, and the light beam receiving module 320 is used to receive the characteristic light beam emitted by the first light source 310. The first light source 310 can be selected as a laser source, and is not limited thereto.

[0080] In the light source column, the first light source 310 and the light beam receiving module 320 are respectively arranged on opposite sides of the reference plane 210 of the light source column. The first light source 310 is arranged on the side facing the reference plane 210 and simultaneously faces the test column 200 adjacent to this light source column, and the light beam receiving module 320 is arranged on the other side facing the reference plane 210 and simultaneously faces another test column 200 adjacent to this light source column.

[0081] The reflection column is provided with a reflector 340.

[0082] In the natural state, under the action of the springback mechanism, the moving parts 500 are all located at the end of the positioning seat 400 away from the reference axis 100. In this state, the distances between all the test columns 200 and the reference axis 100 are the same. The 3 test columns 200 in this embodiment form a triangular relationship.

[0083] At this time, if the first light source 310 of the light source column emits a characteristic light beam, the characteristic light beam will irradiate the test column 200 adjacent to this light source column. The reflector 340 of the test column 200 is used to reflect the characteristic light beam emitted by the first light source 310 of the light source column towards the reflection column, and reflect the characteristic light beam to the adjacent reflection column located on the side away from the incident side of the characteristic light beam of the current reflection column. During the propagation of the characteristic light beam, for the last reflection column, when it reflects the characteristic light beam, it is to reflect the characteristic light beam to the light beam receiving module 320 of the light source column, as Figure 4 shown.

[0084] When performing detection, the reference axis 100 is used to extend into the processing hole 2000 of the workpiece to be measured and is used to be coaxially arranged with the processing hole 2000. That is to say, during detection, it is necessary to extend the reference axis 100 into the processing hole 2000 and make the reference axis 100 and the processing hole 2000 coaxially arranged.

[0085] During the actual machining process, the reference shaft 100 can be accurately inserted into the machining hole 2000 in the following way: just after the machine tool has finished machining the machining hole 2000, align the central axis of the reference shaft 100 with the preset central axis of the hole when the machine tool machines this machining hole 2000, and then insert the reference shaft 100 into the machining hole 2000 along the preset central axis of the hole. And it is not limited to this.

[0086] The beam sensing part is electrically connected to the processor for sending beam detection data to the processor during the rotation of the reference shaft 100. The processor is used to judge whether the machining hole 2000 is qualified according to the beam detection data.

[0087] Specifically, by selecting a positioning seat 400 with an appropriate length, after the reference shaft 100 enters the machining hole 2000, the test column 200 abuts against the hole wall of the machining hole 2000, that is: by selecting a positioning seat 400 with an appropriate length, the distance between the side wall surface of the test column 200 far from the reference shaft 100 and the central axis of the reference shaft 100 in the natural state is greater than the radius of the machining hole 2000 to be detected. In other words, after the reference shaft 100 is accurately inserted into the machining hole 2000, the hole wall of the machining hole 2000 can push the test column 200 towards the side where the reference shaft 100 is located for a certain distance. During this process, the moving part 500 will move towards the reference shaft 100 by a corresponding distance against the elastic force of the spring-back mechanism, and the moving part 500 still has space to continue moving towards the reference shaft 100.

[0088] At this time, if the beam receiving module 320 can still smoothly receive the characteristic beam emitted by the first light source 310, it means that the current optical path is still similar to Figure 4 the optical path shown. In this state, the radii of the machining holes 2000 corresponding to the positions where the 3 test columns 200 are located are the same. This shows that at the initial position of the current test column 200, the radius of the machining hole 2000 is uniform.

[0089] Subsequently, the reference shaft 100 can be controlled to rotate at a preset speed (which can be flexibly set according to the actual situation), and continuously monitor whether the beam receiving module 320 can continuously receive the characteristic beam emitted by the first light source 310. If during the process of traversing the hole wall of the machining hole 2000 at the current insertion depth of the test column 200, the beam receiving module 320 can continuously receive the characteristic beam emitted by the first light source 310, it means that within the range of the inner wall of the machining hole 2000 traversed by the current test column 200, the aperture of the machining hole 2000 is uniform. However, if the beam receiving module 320 fails to receive the characteristic beam emitted by the first light source 310, there is a problem of non-uniform aperture at the position where the test column 200 is located when this situation occurs.

[0090] After the detection of the aperture uniformity at the current insertion depth is completed, by changing the insertion depth of the reference axis 100 into the machining hole 2000, the detection of the remaining part of the machining hole 2000 can be continued. Optionally, the length of the test column 200 can also be set to be adapted to the hole depth of the machining hole 2000 to improve the detection efficiency.

[0091] It can be understood that the workpiece machining quality detection mechanism is more suitable for detecting the aperture uniformity when the type of the machining hole 2000 is a through hole.

[0092] It should be noted that the detection accuracy of the workpiece machining quality detection mechanism can be adjusted by adjusting the reception accuracy of the beam receiving module 320 when receiving the characteristic beam (that is: after the characteristic beam deviates by how much distance, the beam receiving module 320 cannot smoothly receive it).

[0093] Through the above design, the comprehensive detection of the inner surface uniformity of the machining hole 2000 is realized, and the comprehensiveness of the machining quality control of the machining hole 2000 is improved.

[0094] Generally speaking, the workpiece machining quality detection mechanism provided in this embodiment can effectively improve the comprehensiveness of the detection of the inner surface of the machining hole 2000, overcome the limitations of the traditional detection method, and can more reasonably reflect the actual machining quality of the machining hole 2000, which has positive significance for further improving the machining accuracy.

[0095] In this embodiment, the test column 200 includes a core body 220 and a rotating sleeve 230.

[0096] The rotating sleeve 230 is in a cylindrical shape, and the rotating sleeve 230 is rotatably sleeved on the core body 220. The test column 200 is cooperated with the moving part 500 through the core body 220. The rotating sleeve 230 is made of a light-transmitting material, and the specific material can be flexibly selected according to the actual situation.

[0097] In the light source column, both the first light source 310 and the beam receiving module 320 are embedded in the core body 220 and both are arranged along the radial direction of the rotating sleeve 230.

[0098] In the reflection column, the reflector 340 is arranged on the core body 220. The reflection surface of the reflector 340 is perpendicular to the reference surface 210, and the central axis of the reflection column is located in the plane corresponding to the reflection surface of the reflector 340.

[0099] In the reflection column, the core body 220 is in a cylindrical shape, the core body 220 is coaxially arranged with the rotating sleeve 230, and the outer side wall of the core body 220 is attached to the inner side wall of the rotating sleeve 230.

[0100] The core body 220 of the reflection column is also made of a light-transmitting material, and the reflector 340 is embedded in the core body 220.

[0101] In the light source column, the core body 220 is cylindrical, the core body 220 is coaxially arranged with the rotating sleeve 230, and the outer side wall of the core body 220 is attached to the inner side wall of the rotating sleeve 230.

[0102] The core body 220 of the light source column is provided with mounting holes 330, the mounting holes 330 are arranged along the radial direction of the core body 220, and the first light source 310 and the beam receiving module 320 are respectively installed in different mounting holes 330.

[0103] When the workpiece machining quality detection mechanism is in the natural state, or when the reference shaft 100 extends into the machining hole 2000 which is a standard round hole, the characteristic light beam is emitted along the radial direction of the light source column and shoots towards the reflecting member 340 along the radial direction of the reflecting column. At the same time, the characteristic light beam also intersects with the central axis of the reflecting column.

[0104] If the hole wall of the machining hole 2000 is uneven, when the light source column and / or the reflecting column move to the uneven position, it will cause a certain deflection of the light source column and / or the reflecting column, thus destroying the original light path and causing the beam receiving module 320 to be unable to receive the characteristic light beam. This is used as the detection basis for the uneven position on the hole wall of the machining hole 2000.

[0105] In this embodiment, the positioning seat 400 includes: two groups of rod bodies 410.

[0106] The two groups of rod bodies 410 are both arranged at intervals along the axial direction of the reference shaft 100 and both are arranged along the radial direction of the reference shaft 100, and the test column 200 is located between the two groups of rod bodies 410.

[0107] Chute 411 is provided at one end of the rod body 410 away from the reference shaft 100, and the moving member 500 is slidably fitted in the chute 411.

[0108] Both ends of the core body 220 are provided with a first fitting column 221 and a second fitting column 222. The first fitting column 221 and the second fitting column 222 are coaxially and fixedly connected and both are arranged along the axial direction of the test column 200. The first fitting column 221 is fixedly connected to the core body 220, the outer diameter of the first fitting column 221 is smaller than the outer diameter of the core body 220, and the outer diameter of the second fitting column 222 is smaller than that of the first fitting column 221.

[0109] A fitting notch is provided on the moving member 500, and a fitting block 520 is rotatably fitted in the fitting notch. The rotation axis line of the fitting block 520 is perpendicular to the central axis of the reference shaft 100, and the rotation axis line of the fitting block 520 is also perpendicular to the rod body 410.

[0110] A fitting through hole is provided in the fitting block 520 of the moving member 500, the aperture of the fitting through hole is adapted to the outer diameter of the second fitting column 222, and the second fitting column 222 is fitted in the fitting through hole.

[0111] When the test column 200 is parallel to the reference axis 100, the first mating columns 221 at both ends of the core body 220 are in contact with the mating blocks 520 of the moving member 500, and the second mating columns 222 extend beyond the mating blocks 520, that is, a part of the second mating columns 222 extends to the side of the mating blocks 520 away from the core body 220. Along the circumferential length direction of the core body 220, the second mating columns 222 are in sliding fit with the mating blocks 520; along the circumference of the core body 220, the second mating columns 222 are in fixed fit with the mating blocks 520, that is, the second mating columns 222 will not rotate relative to the mating blocks 520.

[0112] During detection, the reference axis 100 extends into the machining hole 2000, and the test column 200 is in contact with the hole wall of the machining hole 2000. Subsequently, the rotation of the reference axis 100 can also be controlled to enable the test column 200 to move along the circumference of the machining hole 2000 on the hole wall of the machining hole 2000, so as to detect the machining hole 2000 in the circumferential direction. In addition, by adjusting the insertion depth of the reference axis 100 extending into the machining hole 2000, the detection of the entire inner wall of the machining hole 2000 can be realized.

[0113] During the rotation of the reference axis 100, since the core body 220 is restricted by the mating blocks 520, the core body 220 will not rotate, so the rotating sleeve 230 will rotate relative to the core body 220. Due to the special structural design of the rotating sleeve 230 and the core body 220, during the movement of the rotating sleeve 230 along the hole wall of the machining hole 2000, the optical path of the first light source 310 will not be affected.

[0114] Through this design, the workpiece machining quality detection mechanism is more suitable for the automatic detection after the machining of the machining hole 2000 by the machine tool, and has a higher adaptability to automatic production.

[0115] Furthermore, please refer to Figures 7-10 , the positioning seat 400 further includes: a connecting arm 420. The connecting arm 420 is fixedly connected between two groups of rod bodies 410 of the same positioning seat 400. The connecting arm 420 is arranged along the axial direction of the reference axis 100, and the connecting arm 420 is fixedly connected to the end of the rod body 410 close to the reference axis 100.

[0116] The rod body 410 also has a receiving cavity 412 extending along its axial direction. The receiving cavity 412 is located on the side of the sliding groove 411 close to the reference axis 100, and the receiving cavity 412 extends to communicate with the cavity of the sliding groove 411.

[0117] A sliding block 510 is fixedly connected to the side of the moving member 500 close to the receiving cavity 412. The sliding block 510 extends into the receiving cavity 412 and is in sliding fit with the receiving cavity 412, and the sliding block 510 is in sliding seal with the receiving cavity 412.

[0118] The connecting arm 420 has a mounting inner cavity 421.

[0119] The elastic return mechanism includes: a first tube body 610, a second tube body 620, and a third tube body 630 that are connected in sequence and communicate with each other.

[0120] Both the first tube body 610 and the third tube body 630 are arranged along the length direction of the connecting arm 420 (the axial direction of the reference axis 100), and the second tube body 620 is arranged along the width direction of the connecting arm 420 (the radial direction of the reference axis 100).

[0121] The first tube body 610 communicates with the accommodating cavity 412. A detection rod 640 is slidably fitted in the third tube body 630, and there is a sliding seal between the detection rod 640 and the third tube body 630. One end of the detection rod 640 close to the second tube body 620 is fixedly connected to a return spring rod 650. The outer diameter of the return spring rod 650 is smaller than the inner diameter of the third tube body 630. The return spring rod 650 extends along the axial direction of the third tube body 630, penetrates through the end wall of the third tube body 630 and extends outside the third tube body 630, and there is a sliding seal between the return spring rod 650 and the end wall of the third tube body 630.

[0122] The inner diameters of the first tube body 610, the second tube body 620, and the third tube body 630 are all the same as the inner diameter of the accommodating cavity 412.

[0123] Between the end of the return spring rod 650 far from the detection rod 640 and the third tube body 630, there is an elastic member 660 in abutment. The elastic member 660 is provided with a pressure detection mechanism (not shown in the figure) for detecting its elastic force, and the pressure detection mechanism is electrically connected to the processor.

[0124] The accommodating cavity 412, the first tube body 610, the second tube body 620, and the third tube body 630 are filled with a liquid medium.

[0125] In the natural state, the elastic member 660 drives the return spring rod 650 to move outside the third tube body 630, thereby driving the detection rod 640 to move into the third tube body 630, and then driving the sliding block 510 to the end of the accommodating cavity 412 far from the reference axis 100 through the liquid medium, so as to provide a return elastic force for the moving part 500 toward the side away from the reference axis 100, as Figure 7 and Figure 8 shown.

[0126] The processor is used to judge whether the processing hole 2000 is qualified according to the detection data of the pressure detection mechanism.

[0127] Specifically, during the rotation of the reference axis 100, if the inner wall of the machined hole 2000 is uneven, but when the test column 200 moves to the uneven position, if all the test columns 200 move the same distance synchronously along the radial direction of the reference axis 100 towards the side closer to the reference axis 100, or all the test columns 200 move the same distance synchronously along the radial direction of the reference axis 100 towards the side away from the reference axis 100, the beam receiving module 320 can also successfully receive the characteristic beam.

[0128] At this time, due to the radial movement of the test column 200, the sliding block 510 will move along the accommodating cavity 412, resulting in the synchronous movement of the detection rod 640 and the return spring rod 650. This causes the compression amount of the elastic member 660 to change, and the elastic force detected by the pressure detection mechanism is also different. Therefore, the detection data of the pressure detection mechanism can be combined to assist in determining whether the hole wall of the machined hole 2000 is uniform. Exemplarily, as Figure 9 and Figure 10 shown, if all the test columns 200 move the same distance synchronously along the radial direction of the reference axis 100 towards the side closer to the reference axis 100, the return spring rod 650 will move further into the third tube body 630, and the elastic force of the elastic member 660 will increase.

[0129] Since the two groups of rod bodies 410 are relatively independent and each is equipped with a corresponding return mechanism, the two groups of rod bodies 410 are relatively independent during the detection. The deflection situation of the test column 200 during deflection by the mirror method of the reference axis 100 can be determined by determining the displacement direction and displacement amount of the detection rods 640 corresponding to the two groups of rod bodies 410. For example, it can be determined whether the two ends of the test column 200 deflect towards the side where the reference axis 100 is located or towards the side away from the reference axis 100 according to the displacement direction and displacement amount of the detection rods 640 corresponding to the two groups of rod bodies 410, and the difference in the offset amounts of the two ends of the test column 200 can be determined by comparing the displacement amount differences of the detection rods 640, so as to determine which end of the test column 200 is closer to the reference axis 100 during the deflection process, thus restoring the lateral deflection posture of the test column 200. If one end of the test column 200 is closer to the reference column during the offset, it means that there is a protrusion on the hole wall of the machined hole 2000 at the position corresponding to this end of the test column 200 (compared with the hole wall of the standard round hole). If one end of the test column 200 is farther away from the reference column during the offset, it means that there is a depression on the hole wall of the machined hole 2000 at the position corresponding to this end of the test column 200 (compared with the hole wall of the standard round hole).

[0130] Based on this, the uneven positions on the inner wall of the machined hole 2000 can be assisted in positioning.

[0131] Optionally, the flow area inside the third tube body 630 is smaller than the flow area inside the accommodation cavity 412, thereby improving the movement sensitivity of the detection rod 640 and the return spring rod 650, and further improving the detection sensitivity of the pressure detection mechanism.

[0132] The reference axis 100 is provided with an adjustment groove 110 which is opened along the radial direction of the reference axis 100 and extends along the axial direction of the reference axis 100. Along the radial direction of the reference axis 100, the positioning seat 400 is slidably fitted in the adjustment groove 110 and driven by a driver (not shown in the figure). Optionally, all the positioning seats 400 are synchronously driven by the driver.

[0133] This embodiment also provides a high-quality machining automatic machine tool, which includes: a hole machining mechanism and the above workpiece machining quality detection mechanism. The high-quality machining automatic machine tool can use the workpiece machining quality detection mechanism to detect the machined hole 2000 during or after the hole machining mechanism processes the hole, so as to determine whether the uniformity of the machined hole 2000 is qualified and whether the machined hole 2000 needs to be corrected.

[0134] Optionally, the reflecting member 340 is continuously extended along the axial direction of the test column (reflecting column), and both ends of the reflecting member 340 extend to the two end portions of the core body 220 respectively. Correspondingly, both the first light source 310 and the light beam receiving module 320 are multiple. Each first light source 310 is correspondingly provided with a light beam receiving module 320. A combination of a first light source 310 and a light beam receiving module 320 constitutes a "light beam emission + reception" combination. Multiple groups of "light beam emission + reception" combinations are arranged at equal intervals along the axial direction of the test column (light source column).

[0135] Through this design, the detection sensitivity and detection accuracy can be further improved. In addition, it is more convenient to calibrate the test column 200, that is, it is more convenient to adjust the test column 200 to be parallel to the reference axis 100 when no detection is performed (in the natural state).

[0136] Embodiment Two

[0137] Please combine Figures 11-16 Compared with the workpiece machining quality detection mechanism provided in Embodiment One, at the end of the detection rod 640 of the workpiece machining quality detection mechanism provided in this embodiment, which is far away from the return spring rod 650, a driving rack 700 is fixedly connected. The driving rack 700 extends along the length direction of the detection rod 640, and the outer diameter of the driving rack 700 is smaller than the inner diameter of the third tube body 630.

[0138] An auxiliary mechanism 800 is further provided in the installation inner cavity 421 of the connecting arm 420. The auxiliary mechanism 800 includes: a reference ring 810, a first rotating wheel 820 and a second rotating wheel 830.

[0139] The reference ring 810 is in a circular ring shape, and both the first rotating wheel 820 and the second rotating wheel 830 are circular wheels. The reference ring 810 is fixedly installed in the installation inner cavity 421. A projection screen 811 is provided on the inner ring wall of the reference ring 810. The projection screen 811 continuously extends circumferentially along the reference ring 810 to form a ring shape, and scale marks are marked on the projection screen 811 along the circumferential direction of the reference ring 810. The scale marks can be selected as: length marks, angle (central angle) marks, etc., and are not limited thereto.

[0140] The first rotating wheel 820 and the second rotating wheel 830 are respectively arranged on opposite sides of the reference ring 810. The reference ring 810, the first rotating wheel 820, and the second rotating wheel 830 are coaxially arranged, and both the first rotating wheel 820 and the second rotating wheel 830 are rotatably fitted to the reference ring 810. In this embodiment, both the first rotating wheel 820 and the second rotating wheel 830 are in contact with the reference ring 810.

[0141] A central column 831 and a limiting ring 832 are fixedly connected to the side of the second rotating wheel 830 close to the reference ring 810. The central column 831 is a cylinder, and the limiting ring 832 is in a circular ring shape. The inner diameter of the limiting ring 832 is greater than the outer diameter of the central column 831, and the central column 831 is arranged inside the limiting ring 832. The central column 831, the limiting ring 832, and the second rotating wheel 830 are coaxially arranged. Both the central column 831 and the limiting ring 832 extend into the reference ring 810.

[0142] The side wall of the central column 831 is treated with a mirror finish.

[0143] The limiting ring 832 is provided with a light-transmitting notch 833, and the light-transmitting notch 833 penetrates from the outer ring wall of the limiting ring 832 to its inner ring wall. Along the axial direction of the central column 831, the light-transmitting notch 833 is located in the middle of the limiting ring 832; along the circumferential direction of the limiting ring 832, the light-transmitting notch 833 continuously extends, and the light-transmitting notch 833 does not extend into a complete ring shape, that is, the two ends of the light-transmitting notch 833 do not intersect.

[0144] In the circumferential direction of the limiting ring 832, the two end walls of the light-transmitting notch 833 are respectively used as the first end wall 834 and the second end wall 835. Along the length direction of the light-transmitting notch 833, in the direction from the first end wall 834 to the second end wall 835 (i.e., the K direction as shown in Figure 13 ), the width of the light-transmitting notch 833 increases. In this embodiment, the inner walls on both sides of the light-transmitting notch 833 are symmetrically distributed on the limiting ring 832, as shown in Figure 15 and Figure 16 .

[0145] On one side of the first rotating wheel 820 close to the reference ring 810, a second light source 821 and a vision component 822 are fixedly connected, and both the second light source 821 and the vision component 822 extend into the reference ring 810.

[0146] The second light source 821 is arranged towards the central column 831 to emit a detection light beam towards the side wall (mirror surface) of the central column 831, so that the detection light beam can irradiate the side wall of the central column 831 through the light-transmitting notch 833 of the limiting ring 832, and after being reflected by the side wall of the central column 831, it is projected onto the projection screen 811 through the light-transmitting notch 833 of the limiting ring 832 again. The second light source 821 is a line light source, that is, the projection of the detection light beam emitted by the second light source 821 is in a strip shape, and the linear light beam of the second light source 821 is arranged along the length direction of the central column 831. The length of the linear light beam of the second light source 821 is greater than the maximum width of the light-transmitting notch 833.

[0147] Among them, when the second light source 821 emits a detection light beam, the light segment in the detection light beam that shoots towards the central column 831 is used as the first light segment 823, and the light segment in the detection light beam that shoots towards the projection screen 811 is used as the second light segment 824. The first light segment 823 is located on the side of the second light segment 824 close to the first end wall 834 of the light-transmitting notch 833.

[0148] In the natural state, that is, when the moving part 500 is located at the end of the sliding groove 411 far from the accommodating cavity 412, the first light segment 823 and the second light segment 824 are located in the middle area of the light-transmitting notch 833.

[0149] The vision component 822 is used to obtain the projection image of the detection light on the projection screen 811, and the vision component 822 is electrically connected to the processor.

[0150] Both the first rotating wheel 820 and the second rotating wheel 830 have external gear rings. The driving rack 700 of the detection rod 640 at one end of the connecting arm 420 meshes with the first rotating wheel 820, and the driving rack 700 of the detection rod 640 at the other end of the connecting arm 420 meshes with the second rotating wheel 830. When the driving racks 700 of the detection rods 640 at both ends of the connecting arm 420 move towards the side away from the return spring rod 650, both the first rotating wheel 820 and the second rotating wheel 830 are driven in the same direction.

[0151] In this embodiment, for the two moving parts 500 at both ends of the connecting arm 420, when the two moving parts 500 slide the same distance in the same direction along the sliding groove 411, the corresponding detection rods 640 of the two moving parts 500 will move correspondingly. The moving distances of the two detection rods 640 are also the same, and the angles by which the two detection rods 640 drive the first rotating wheel 820 and the second rotating wheel 830 to rotate are also the same.

[0152] With this design, when the machined hole 2000 is a standard round hole, during the rotation of the reference shaft 100, the moving part 500 will not further push the slider 510, the detection rod 640 will not move, neither the first rotating wheel 820 nor the second rotating wheel 830 will rotate, and there is no relative rotation between the first rotating wheel 820 and the second rotating wheel 830. At this time, the position of the projected image on the projection screen 811 will not change, and the length of the projected image on the projection screen 811 will not change either.

[0153] When the test column 200 moves integrally and synchronously along the radial direction of the reference shaft 100 towards or away from one side of the reference shaft 100, the moving distances of the two driving racks 700 are the same, the first rotating wheel 820 and the second rotating wheel 830 rotate in the same direction by the same angle, and there is no relative rotation between the first rotating wheel 820 and the second rotating wheel 830. At this time, taking the example that both the first rotating wheel 820 and the second rotating wheel 830 rotate the same distance along the Figure 13 P direction shown in the figure, the first light source and the limiting ring 832 do not rotate differently, and their relative position relationship will not change. The position of the projected image on the projection screen 811 will change, and the amount of position change corresponds to the rotation angles of the first rotating wheel 820 and the second rotating wheel 830, but the length of the projected image on the projection screen 811 will not change.

[0154] Only when the moving distances of the two ends of the test column 200 relative to the reference shaft 100 are different, there will be relative rotation between the first rotating wheel 820 and the second rotating wheel 830. When there is relative rotation between the first rotating wheel 820 and the second rotating wheel 830, there will be the following situations:

[0155] (1) The first rotating wheel 820 does not rotate relative to the reference ring 810, and only the second rotating wheel 830 rotates relative to the reference ring 810: The position of the projected image on the projection screen 811 will not change, but the length of the projected image on the projection screen 811 will change, and the relative rotation amount between the first rotating wheel 820 and the second rotating wheel 830 corresponds to the length change amount of the projected image.

[0156] (2) The second rotating wheel 830 does not rotate relative to the reference ring 810, and only the first rotating wheel 820 rotates relative to the reference ring 810: The position of the projected image on the projection screen 811 will change, and the length of the projected image on the projection screen 811 will also change. Among them, "the amount of position change of the projected image on the projection screen 811" is the same as "the relative rotation amount corresponding to the length change amount of the projected image".

[0157] (3) The first rotating wheel 820 and the second rotating wheel 830 rotate in the same direction, and the rotation amount of the first rotating wheel 820 is greater than that of the second rotating wheel 830: The position of the projection image on the projection screen 811 will change, and the length of the projection image on the projection screen 811 will also change. Among them, the position change amount of the projection image on the projection screen 811 = the rotation amount of the second rotating wheel 830 + the relative rotation amount corresponding to the length change amount of the projection image.

[0158] (4) The first rotating wheel 820 and the second rotating wheel 830 rotate in the same direction, and the rotation amount of the first rotating wheel 820 is less than that of the second rotating wheel 830: The position of the projection image on the projection screen 811 will change, and the length of the projection image on the projection screen 811 will also change. Among them, the position change amount of the projection image on the projection screen 811 + the relative rotation amount corresponding to the length change amount of the projection image = the rotation amount of the second rotating wheel 830.

[0159] (5) The first rotating wheel 820 and the second rotating wheel 830 rotate in opposite directions: The position change vector of the projection image on the projection screen 811 + the rotation vector of the second rotating wheel 830 = the relative rotation vector corresponding to the length change amount of the projection image.

[0160] Through the above design, it can be judged whether there is relative rotation between the first rotating wheel 820 and the second rotating wheel 830, and further it can be judged whether there is a displacement difference at both ends of the test column 200, which can be used as an auxiliary judgment basis for whether the hole wall of the processing hole 2000 is compliant. In this way, the problem that "the detection accuracy is affected due to the change of the elastic force of the elastic member 660 caused by the significant change of the temperature in the working environment" can be effectively avoided.

[0161] Further, in this embodiment, the second light source 821 and the vision component 822 are installed on a substrate 825. The substrate 825 is fixedly connected to the side wall of the first rotating wheel 820, and the substrate 825 extends into the reference ring 810. A cleaning brush 826 is connected to the side of the substrate 825 away from the central column 831. The cleaning brush 826 is in contact with the projection screen 811 for cleaning the projection screen 811.

[0162] Through this design, when the first rotating wheel 820 moves relative to the reference ring 810, the projection screen 811 can be cleaned synchronously. Among them, the cleaning brush 826 can be arranged to extend along the circumferential direction of the projection screen 811, and the specific extension length of the cleaning brush 826 can be flexibly set according to actual needs.

[0163] In summary, the workpiece processing quality detection mechanism provided by the embodiments of the present invention can effectively improve the comprehensiveness of the detection of the inner surface of the processing hole 2000, overcome the limitations of the traditional detection method, and can more reasonably reflect the actual processing quality of the processing hole 2000, which has a positive significance for further improving the processing accuracy.

[0164] The high-quality processing automatic machine tool provided by the embodiments of the present invention can effectively improve the comprehensiveness of the detection of the inner surface of the processing hole 2000, overcome the limitations of the traditional detection method, and can more reasonably evaluate the actual processing quality of the processing hole 2000 during the processing process, thereby further improving the processing accuracy of the processing hole 2000.
