Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of linear size measurement, in particular to a hole part batch go-no-go gauge detection device. BACKGROUND

[0002] Go-no-go gauge is the most basic limit gauge in mechanical manufacturing, and is widely used to quickly determine whether the key size of a workpiece is within the design tolerance range, such as the tolerance range of hole diameter, shaft diameter and groove width. In the early days, the workpiece was detected by manually holding the go-no-go gauge, which had the problems of low efficiency and poor accuracy. With the continuous development of technology, automatic visual go-no-go gauge detection devices began to appear, which did not require manual detection and directly detected the detection results of the go-no-go gauge through a vision sensor, greatly improving the detection efficiency and accuracy. However, there are still many shortcomings, such as when the go-no-go gauge detects the hole diameter of the workpiece, the go-no-go gauge is often forced into the hole due to excessive mechanical pressure, causing misjudgment of the hole diameter within the tolerance range, and also damaging the workpiece. At the same time, burr defects in the hole will also affect the detection of the go-no-go gauge, causing misjudgment of the hole diameter within the tolerance size range as unqualified. Therefore, we need a hole part batch go-no-go gauge detection device to solve the above problems. SUMMARY

[0003] The present application aims to provide a hole part batch go-no-go gauge detection device to solve the problems in the prior art.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: The go-no-go gauge detection device comprises a workbench, a clamping module, a conveying module, a go-no-go gauge module, a detection pressure limiting module and a burr removal module. The clamping module is fixedly arranged on the workbench. The conveying module is arranged on one side of the clamping module and is fixedly connected with the workbench. The go-no-go gauge module is arranged on the other side of the clamping module and is fixedly connected with the workbench. The detection pressure limiting module is fixedly connected with the go-no-go gauge module. The burr removal module is fixedly arranged in the workbench and is located below the clamping module. The go-no-go gauge module comprises a lifting unit, a stop gauge unit and a go gauge unit. The lifting unit comprises a detection cylinder and a go-no-go gauge cylinder. The stop gauge unit comprises a stop gauge, a stop gauge discrimination switch, a stop gauge reset cylinder and a magnetic block. The go gauge unit comprises a go gauge, a go gauge reset spring and a go gauge discrimination switch.

[0005] The go-no-go gauge detection device is controlled by an external console, which can receive signals from the go-no-go gauge block and the detection pressure limiting module, and can control the operation of the clamping module, the conveying module, the go-no-go gauge block, the detection pressure limiting module and the burr removing module. The workbench provides a stable and flat support platform for the entire go-no-go gauge detection device. The clamping module is used for positioning and clamping the workpiece, the conveying module is used for feeding and discharging the workpiece, the go-no-go gauge block is used for detecting and judging whether the hole diameter of the workpiece to be measured meets the specified size tolerance requirements, the detection pressure limiting module is used to ensure that the detection pressure of the go-no-go gauge block on the workpiece to be measured is consistent, and the burr removing module is used to remove the burr in the workpiece to be measured before the go-no-go gauge block detects, so as to prevent the burr from affecting the accuracy of detection.

[0006] Further, a cleaning chamber is arranged between the workbench and the clamping module, and the burr removing module is arranged in the cleaning chamber.

[0007] The cleaning chamber is used to accommodate the burr removing module and collect the falling burrs, so as to ensure the cleanliness of the workshop.

[0008] Further, the clamping module includes a clamping base, a left clamping cylinder, a right clamping cylinder, a left clamping piece and a right clamping piece. The clamping base is fixedly connected with the workbench, the chamber between the clamping base and the workbench is the cleaning chamber, the clamping base is provided with a workpiece positioning groove, the clamping base is provided with a through hole, the through hole communicates the workpiece to be measured hole with the cleaning chamber, the center axis of the through hole and the workpiece to be measured hole coincide, the closer the through hole is to the workpiece to be measured hole, the larger the radius of the through hole is, the clamping base is provided with an air passage, the inlet of the air passage communicates with an external air blower, the outlet of the air passage communicates with the through hole, there is a tangential angle of 10° to 30° between the outlet of the air passage and the side wall of the through hole, the left clamping piece is located on one side of the workpiece positioning groove, the left clamping cylinder is fixedly connected with the clamping base, the output end of the left clamping cylinder is fixedly connected with the end face of the left clamping piece away from the workpiece positioning groove, the right clamping piece is located on the other side of the workpiece positioning groove, the right clamping cylinder is fixedly connected with the clamping base, and the output end of the right clamping cylinder is fixedly connected with the end face of the right clamping piece away from the workpiece positioning groove.

[0009] The workpiece positioning groove is used for positioning and placing the workpiece. After the conveying module places the workpiece in the workpiece positioning groove, the left clamping cylinder and the right clamping cylinder are started to push the left clamping piece and the right clamping piece respectively to clamp the workpiece. Then, the external air blower and the burr removing module are started simultaneously. The external air blower blows air into the air guiding groove through the through hole. Because the outlet of the air guiding groove and the side wall of the through hole have a tangential angle of 10° to 30°, and the closer the through hole is to the workpiece to-be-measured hole, the larger the radius of the through hole is, the air flow forms a rotating air flow like a tornado in the through hole. Under the action of the rotating air flow like a tornado, the sheared burr debris quickly separates from the inner wall of the workpiece to-be-measured hole, avoiding scratching the inner wall, and at the same time, the burr debris quickly falls into the cleaning chamber.

[0010] Further, the conveying module comprises a rotating base, a lifting cylinder and a pneumatic clamping jaw. The rotating base can rotate by 360°. The rotating base is fixedly connected to the workbench. The lifting cylinder is fixedly connected to one end of the rotating base. The output end of the lifting cylinder is fixedly connected to the pneumatic clamping jaw.

[0011] The rotating base can rotate by 360°, which facilitates grabbing the workpiece from different directions or sending the workpiece to different directions.

The stop gauge unit is fixedly connected to the lifting unit. The top end of the through gauge unit is inserted into the stop gauge unit from the bottom end of the stop gauge unit. The through gauge unit is slidingly connected to the stop gauge unit.

[0013] The lifting unit is responsible for driving the detection pressure limiting module, the stop gauge unit and the through gauge unit to move up and down, and is also responsible for providing the detection pressure of the detection pressure limiting module, the stop gauge unit and the through gauge unit. When the through gauge unit passes through the workpiece to-be-measured hole, it indicates that the hole diameter does not exceed the maximum limit size. When the stop gauge unit cannot be smoothly inserted into the workpiece to-be-measured hole, it indicates that the hole diameter does not exceed the minimum limit size. Only when both of the above conditions are met, it is determined that the hole diameter of the workpiece to-be-measured hole is within the allowable size tolerance range.

[0014] Further, the lifting unit further comprises a fixing frame. The fixing frame is fixedly connected to the workbench. The detection cylinder is fixedly connected to the fixing frame. The output end of the detection cylinder is fixedly connected to the detection pressure limiting module. The through-stop gauge cylinder is fixedly connected to the fixing frame. The output end of the through-stop gauge cylinder is fixedly connected to the stop gauge unit. The detection cylinder and the through-stop gauge cylinder are the same specification cylinders. The detection cylinder and the through-stop gauge cylinder are controlled by the same electrical signal. The output ends of the detection cylinder and the through-stop gauge cylinder are flush in the vertical direction.

[0015] The detection cylinder is responsible for driving the detection pressure limiting module to move up and down, the go-no-go gauge cylinder is responsible for driving the go gauge unit and the no-go gauge unit to move up and down, the detection cylinder and the go-no-go gauge cylinder are started at the same time when working, and the extension and retraction amounts are consistent, so that the detection pressure limiting module and the no-go gauge unit are ensured to contact the workpiece at the same time, and as the output ends of the detection cylinder and the go-no-go gauge cylinder are continuously extended, the pressure variation amount and the variation rate of the detection pressure limiting module and the no-go gauge unit on the workpiece are also always consistent, and the maximum pressure of the no-go gauge unit on the workpiece is ensured to be within the always limited range.

[0016] Further, the no-go gauge unit further comprises a mounting box, an upper end surface of the mounting box is fixedly connected with the output end of the go-no-go gauge cylinder, a visual sensor for observing the distance between the no-go gauge and the hole to be detected of the workpiece is arranged on the mounting box, two no-go gauges and two no-go gauge reset cylinders are respectively arranged, the top ends of the two no-go gauges are inserted into the mounting box, the two no-go gauges are slidably connected with the mounting box, the bottom end surfaces of the two no-go gauges are flush in the vertical direction, the top end of the go gauge unit is inserted into the two no-go gauges from the bottom ends of the two no-go gauges, the go gauge unit is slidably connected with the two no-go gauges, the top ends of the two no-go gauges are respectively provided with a magnetic block, the two magnetic blocks are fixedly connected with one no-go gauge respectively, the two no-go gauge reset cylinders are fixedly connected with the mounting box, the output end of one no-go gauge reset cylinder is fixedly connected with the top end of one no-go gauge, the output end of the other no-go gauge reset cylinder is fixedly connected with the top end of the other no-go gauge, and the two no-go gauge discrimination switches are fixedly connected with the mounting box and located above the two no-go gauges respectively.

[0017] The two no-go gauge discrimination switches are both contact type switches, in a detection process, when the two no-go gauge discrimination switches are closed at the same time, a signal is sent to the external control console, the external control console receives the signal to determine that the no-go gauge below the switch cannot pass through the corresponding hole to be detected of the workpiece, the diameter of the corresponding hole to be detected of the workpiece is within the allowable size tolerance range, the external control console controls the conveying module to convey the workpiece to the qualified workpiece collection place; at the end of the detection process, if one of the two no-go gauge discrimination switches is not closed or both are not closed, the external control console determines that the diameter of the corresponding hole to be detected of the workpiece is not within the allowable size tolerance range, the external control console controls the conveying module to convey the workpiece to the unqualified workpiece collection place, the no-go gauge reset cylinder is used to restore the no-go gauge to the original position, when the no-go gauge reset cylinder is not started, the friction when the extension end of the no-go gauge reset cylinder extends is almost negligible, the visual sensor on the mounting box transmits the observation result to the external control console to directly determine whether the diameter of the hole to be detected of the workpiece is within the allowable size tolerance range, at the same time, the external control console compares the detection results of the no-go gauge unit and the go gauge unit with the detection result of the visual sensor, if the comparison result is inconsistent, the checking result of the visual sensor is used as the reference, and it is determined that the no-go gauge unit or the go gauge unit is malfunctioning, and the no-go gauge unit or the go gauge unit is stopped for repair.

[0018] Further, two go-gauges, two go-gauge reset springs and two go-gauge discrimination switches are arranged, the top ends of the two go-gauges are inserted into the bottom ends of the two stop-gauges respectively, the two go-gauges and the stop-gauges inserted respectively are in sliding connection, one end of one go-gauge reset spring is fixedly connected with one stop-gauge, the other end of one go-gauge reset spring is fixedly connected with the top end of one go-gauge, one go-gauge discrimination switch is arranged in one go-gauge reset spring, one go-gauge discrimination switch is fixedly connected with one stop-gauge, one end of the other go-gauge reset spring is fixedly connected with the other stop-gauge, the other end of the other go-gauge reset spring is fixedly connected with the top end of the other go-gauge, the other go-gauge discrimination switch is arranged in the other go-gauge reset spring, the other go-gauge discrimination switch is fixedly connected with the other stop-gauge.

[0019] The two go-gauge discrimination switches are both contact type switches, the go-gauge discrimination switches send signals to the external control console when closed, the external control console controls the return of the extension ends of the detection cylinder and the go-stop gauge cylinder to the original position after receiving the signals, in the case that the go-gauge and the stop-gauge slide by the same distance, the total of the sliding friction between the go-gauge and the stop-gauge and the pushing force of the go-gauge reset spring when compressed is less than the sliding friction between the stop-gauge and the installation box, when the go-gauge unit needs to detect the hole diameter of the hole to be detected of the workpiece, the output end of the go-stop gauge cylinder is constantly elongated to move the go-gauge unit downward, if the two go-gauges can smoothly pass through the hole to be detected of the workpiece, it indicates that the hole diameter of the hole to be detected of the workpiece does not exceed the maximum limit size, at this time, the two go-gauge discrimination switches are not closed, the output end of the go-stop gauge cylinder continues to elongate to perform subsequent detection of the hole to be detected of the workpiece by the stop-gauge unit; if the go-gauge cannot be inserted into the hole to be detected of the workpiece, as the output end of the go-stop gauge cylinder is constantly elongated, the pressure of the go-gauge on the workpiece gradually increases, that is, the reaction force of the workpiece on the go-gauge gradually increases, when the reaction force is greater than the sliding friction between the go-gauge and the stop-gauge, the go-gauge reset spring is compressed until the corresponding go-gauge discrimination switch is closed, until the go-gauge discrimination switch sends signals to the external control console, the external control console receives the signals to determine that the hole to be detected of the workpiece exceeds the maximum limit size and does not meet the specifications, then the return of the extension ends of the detection cylinder and the go-stop gauge cylinder to the original position is controlled, and the detection of the hole to be detected of the next workpiece is waited.

[0020] Further, the detection pressure limiting module comprises a detection box, a detection column, a reset cylinder, a reset switch, a sliding rheostat and electromagnets, the detection box is fixedly connected with the output end of the detection cylinder, the top end of the detection column is inserted into the detection box, the detection column and the detection box are in sliding connection, the sliding rheostat is arranged in the detection box, the sliding rheostat is vertically arranged, the sliding rheostat and the detection box are fixedly connected, the adjusting rod of the sliding rheostat is fixedly connected with the detection column, the electromagnets are arranged in two, the two electromagnets are located above the two magnetic blocks, the two electromagnets and the sliding rheostat are in series connection, the reset switch is fixedly connected with the detection box, and the reset switch is located above the detection column.

[0021] The reset switch is a contact switch. When the reset switch is closed, the reset switch sends a signal to the external control console. The external control console receives the signal and ends the detection of the hole diameter of the workpiece. At this time, the extension ends of the reset cylinder, the detection cylinder and the go-no-go gauge cylinder simultaneously return to the original position. When the electromagnet is powered on, it repels the magnetic block. When the go gauge unit passes through the hole to be detected of the workpiece, the detection cylinder and the bottom end of the stop gauge simultaneously contact the surface of the workpiece as the extension ends of the detection cylinder and the go-no-go gauge cylinder continue to extend to the set length. In this process, the detection cylinder slides relative to the detection box as the reaction force of the workpiece on the detection cylinder gradually increases. The extension end of the reset cylinder is compressed, the resistance value of the sliding rheostat continuously decreases, the current through the electromagnet continuously increases, and the magnetic force of the electromagnet increases. When the resistance value of the sliding rheostat reaches the preset value, the detection cylinder still slides, but the resistance value of the sliding rheostat does not change, i.e. the repulsive force of the electromagnet on the magnetic block no longer increases, thereby ensuring that the force applied by the two stop gauges to the workpiece no longer changes. When the two stop gauges cannot pass through the hole to be detected of the workpiece, the two stop gauges slide relative to the mounting box, and the extension ends of the two stop gauge reset cylinders are compressed. When the two stop gauges slide a certain distance, the repulsive force of the electromagnet on the magnetic block is constant, and the two stop gauges continue to slide until the reset switch is closed. At this time, the stop gauge discrimination switch is closed synchronously. In the process of the continuous sliding of the two stop gauges, the pressure of a single stop gauge on the surface of the workpiece is equal to the sum of the friction between the stop gauge and the mounting box and the size of the repulsive force of the electromagnet on the magnetic block. Since the friction between the stop gauge and the mounting box and the size of the repulsive force of the electromagnet on the magnetic block are constant, the pressure applied to the two stop gauges to the workpiece is always kept constant, thereby preventing the two stop gauges from being forcibly pressed into the hole to be detected of the workpiece due to the increasing pressure, and misjudging the hole diameter that does not meet the allowable size tolerance range. When the stop gauge is inserted into the hole to be detected of the workpiece, in the time period from the opening to the closing of the reset switch, the stop gauge cannot slide to the position of closing the stop gauge discrimination switch in this time period due to the decrease or absence of the reaction force of the workpiece on the stop gauge. That is, the reset switch is closed, but the stop gauge discrimination switch is not closed. Therefore, the external control console determines that the hole diameter of the workpiece to be detected does not meet the allowable size tolerance range, and the external control console immediately controls the conveying module to convey the workpiece to the unqualified workpiece collection place.

[0022] Further, the burr removing module comprises a driving electric cylinder, a motor mounting frame, driving motors, fixed plates, self-adaptive springs and scrapers, the driving electric cylinder is located in the cleaning chamber, the driving electric cylinder is fixedly connected with the workbench, the output end of the driving electric cylinder is fixedly connected with the motor mounting frame, the driving motors and the fixed plates are provided with two, the two driving motors are fixedly connected with the motor mounting frame, the output ends of the two driving motors are fixedly connected with the fixed plates respectively, the rotating axis of one driving motor falls on the symmetry plane of the corresponding fixed plate, the rotating axis of one driving motor coincides with the central axis of the hole to be measured of the workpiece, the rotating axis of the other driving motor falls on the symmetry plane of the other fixed plate connected, the rotating axis of the other driving motor coincides with the central axis of the hole to be measured of the other workpiece, the scrapers are arranged on the two sides of the fixed plates, the scrapers are slidably connected with the fixed plates, the self-adaptive springs are arranged between each scraper and the fixed plate, one end of the self-adaptive spring is fixedly connected with the scraper, and the other end of the self-adaptive spring is fixedly connected with the fixed plate.

[0023] When the burr removing module works, the driving electric cylinder starts, the fixed plate is sent into the hole to be measured of the workpiece, and stops working after the scraper reaches the specified position, then the driving motor starts, drives the fixed plate to rotate, under the action of centrifugal force, the self-adaptive spring is stretched by the scraper, the scraper is tightly attached to the inner wall of the hole to be measured of the workpiece under the action of the elastic force of the self-adaptive spring, and the burr on the inner wall is removed, after the removal is completed, the driving motor stops working, the self-adaptive spring pulls back the scraper, then the driving electric cylinder starts again, and the fixed plate is collected into the cleaning chamber.

[0024] Compared with the prior art, the present application has the following advantages: 1、The present application sets a detection pressure limiting module, when the gauge detects the hole diameter of the hole to be measured of the workpiece, the pressure applied by the gauge to the workpiece can be accurately controlled and limited, preventing the gauge from being forced into the hole to be measured of the workpiece due to the increasing pressure, and misjudging the hole diameter that does not meet the allowable size tolerance range; 2、The burr removing module of the present application can adapt to the hole diameter of the hole to be measured of the workpiece, without active adjustment, it can remove the burr of the hole to be measured of the workpiece with different hole diameters; 3、The clamping base of the present application is provided with an air passage, the inlet of the air passage is communicated with an external air blower, the outlet of the air passage is communicated with the through hole, and there is a tangential angle of 10° to 30° between the outlet of the air passage and the side wall of the through hole. Due to the tangential angle, the closer the through hole is to the hole to be measured of the workpiece, the larger the radius of the through hole, and the airflow forms a rotating airflow like a tornado in the through hole. Under the action of the rotating airflow like a tornado, the sheared burr debris quickly separates from the inner wall of the hole to be measured of the workpiece, avoiding scratching the inner wall, and making the burr debris quickly fall into the cleaning chamber.

When the through gauge unit 43 passes through the hole to be measured of the workpiece, it indicates that the hole diameter does not exceed the maximum limit size; when the stop gauge unit 42 cannot be smoothly inserted into the hole to be measured of the workpiece, it indicates that the hole diameter does not exceed the minimum limit size; only when both of the above conditions are met, it is determined that the hole diameter of the hole to be measured of the workpiece is within the allowable size tolerance range.

[0038] As shown in Figure 1 , the lifting unit 41 further comprises a fixed frame 44, the fixed frame 44 and the workbench 1 are fixedly connected, a detection cylinder 45 and the fixed frame 44 are fixedly connected, the output end of the detection cylinder 45 and the detection pressure limiting module 5 are fixedly connected, a through-stop cylinder 46 and the fixed frame 44 are fixedly connected, the output end of the through-stop cylinder 46 and the stop gauge unit 42 are fixedly connected, the detection cylinder 45 and the through-stop cylinder 46 are the same specification cylinder, the detection cylinder 45 and the through-stop cylinder 46 are controlled by the same electrical signal, and the output ends of the detection cylinder 45 and the through-stop cylinder 46 are flush in the vertical direction.

[0039] The detection cylinder 45 is responsible for driving the detection pressure limiting module 5 to move up and down, the through-stop cylinder 46 is responsible for driving the stop gauge unit 42 and the through gauge unit 43 to move up and down, the detection cylinder 45 and the through-stop cylinder 46 are started at the same time when working, and the extension amounts are consistent, which ensures that the detection pressure limiting module 5 and the stop gauge unit 42 contact the workpiece at the same time, and as the output ends of the detection cylinder 45 and the through-stop cylinder 46 continuously extend, the pressure variation amount and the variation rate of the detection pressure limiting module 5 and the stop gauge unit 42 on the workpiece are also always consistent, and the maximum pressure of the stop gauge unit 42 on the workpiece is always within the limited range.

[0040] As shown in Figure 3 and Figure 7As shown, the stop gauge unit 42 further comprises a mounting box 47, the upper end surface of the mounting box 47 is fixedly connected with the output end of the stop gauge cylinder 46, a visual sensor for observing the distance between the stop gauge 48 and the hole to be measured of the workpiece is arranged on the mounting box 47, the stop gauge 48, the stop gauge discrimination switch 49, the stop gauge reset cylinder 410 and the magnetic block 411 are respectively provided with two, the top end of the two stop gauges 48 is inserted into the mounting box 47, the two stop gauges 48 are slidingly connected with the mounting box 47, the bottom end surface of the two stop gauges 48 is flush in the vertical direction, the top end of the two stop gauges 48 is provided with a magnetic block 411, the two magnetic blocks 411 are respectively fixedly connected with one stop gauge 48, the two stop gauge reset cylinders 410 are fixedly connected with the mounting box 47, the output end of one stop gauge reset cylinder 410 is fixedly connected with the top end of one stop gauge 48, the output end of the other stop gauge reset cylinder 410 is fixedly connected with the top end of the other stop gauge 48, the two stop gauge discrimination switches 49 are fixedly connected with the mounting box 47, and the two stop gauge discrimination switches 49 are located above the two stop gauges 48.

[0041] The two stop gauge discrimination switches 49 are both contact type switches, in a detection process, when the two stop gauge discrimination switches 49 are closed at the same time, a signal is sent to the external control console, the external control console receives the signal to determine that the stop gauge 48 below the switch cannot pass through the corresponding hole to be measured of the workpiece, the diameter of the corresponding hole to be measured of the workpiece is within the allowable size tolerance range, the external control console controls the conveying module 3 to convey the workpiece to the qualified workpiece collection place; at the end of the detection process, if one of the two stop gauge discrimination switches 49 is not closed or both are not closed, the external control console determines that the diameter of the corresponding hole to be measured of the workpiece is not within the allowable size tolerance range, the external control console controls the conveying module 3 to convey the workpiece to the unqualified workpiece collection place, the stop gauge reset cylinder 410 is used to restore the stop gauge 48 to the original position, when the stop gauge reset cylinder 410 is not started, the friction force of the telescopic end is almost negligible, the visual sensor on the mounting box 47 transmits the observation result to the external control console, which is used to directly determine whether the diameter of the hole to be measured of the workpiece is within the allowable size tolerance range, at the same time, the external control console compares the detection results of the stop gauge unit 42 and the through gauge unit 43 with the detection result of the visual sensor, if the comparison result is inconsistent, the inspection result of the visual sensor is used as the standard, and it is determined that the stop gauge unit 42 or the through gauge unit 43 is malfunctioning, and the stop gauge unit 42 or the through gauge unit 43 is stopped for repair.

[0042] As Figure 3 and Figure 7As shown, two go-gauge 412, go-gauge reset spring 413 and go-gauge discrimination switch 414 are provided, the top end of two go-gauge 412 is inserted into two stop gauge 48 respectively, two go-gauge 412 and the inserted stop gauge 48 are slidingly connected, one end of one go-gauge reset spring 413 is fixedly connected with one stop gauge 48, the other end of one go-gauge reset spring 413 is fixedly connected with the top end of one go-gauge 412, one go-gauge discrimination switch 414 is arranged in one go-gauge reset spring 413, one go-gauge discrimination switch 414 is fixedly connected with one stop gauge 48, one end of another go-gauge reset spring 413 is fixedly connected with another stop gauge 48, the other end of another go-gauge reset spring 413 is fixedly connected with the top end of another go-gauge 412, another go-gauge discrimination switch 414 is arranged in another go-gauge reset spring 413, another go-gauge discrimination switch 414 is fixedly connected with another stop gauge 48.

[0043] Two go-gauge discrimination switches 414 are both contact switches, when closed, the go-gauge discrimination switch 414 sends a signal to the external control console, after receiving the signal, the external control console controls the detection cylinder 45 and the go-stop gauge cylinder 46 to return to the original position, in the case that the go-gauge 412 and the stop gauge 48 slide the same distance, the total of the sliding friction between the go-gauge 412 and the stop gauge 48 and the pushing force of the go-gauge reset spring 413 when compressed is less than the sliding friction between the stop gauge 48 and the mounting box 47, when the go-gauge unit 43 needs to detect the hole diameter of the workpiece to be detected, the output end of the go-stop gauge cylinder 46 is constantly elongated, and the go-gauge unit 43 is lowered, if the two go-gauge 412 can smoothly pass through the hole of the workpiece to be detected, it indicates that the hole diameter of the workpiece to be detected does not exceed the maximum limit size, at this time, both go-gauge discrimination switches 414 are not closed, the output end of the go-stop gauge cylinder 46 continues to elongate, and the subsequent stop gauge unit 42 detects the hole of the workpiece to be detected; if there is a go-gauge 412 that cannot be inserted into the hole of the workpiece to be detected, as the output end of the go-stop gauge cylinder 46 is constantly elongated, the pressure of the go-gauge 412 on the workpiece gradually increases, that is, the reaction force of the workpiece on the go-gauge 412 gradually increases, when the reaction force is greater than the sliding friction between the go-gauge 412 and the stop gauge 48, the go-gauge reset spring 413 is compressed, until the corresponding go-gauge discrimination switch 414 is closed, until the go-gauge discrimination switch 414 sends a signal to the external control console, the external control console receives the signal and determines that the hole of the workpiece to be detected exceeds the maximum limit size, which does not meet the specifications, then the external control console controls the detection cylinder 45 and the go-stop gauge cylinder 46 to return to the original position, and waits for the detection of the hole of the next workpiece to be detected.

[0044] As Figure 6As shown, the detection pressure limiting module 5 comprises a detection box 51, a detection column 52, a reset electric cylinder 53, a reset switch 54, a sliding rheostat 55 and electromagnets 56, the detection box 51 is fixedly connected with the output end of the detection cylinder 45, the top end of the detection column 52 is inserted into the detection box 51, the detection column 52 and the detection box 51 are slidingly connected, the sliding rheostat 55 is arranged in the detection box 51, the sliding rheostat 55 is vertically arranged, the sliding rheostat 55 is fixedly connected with the detection box 51, the adjusting rod of the sliding rheostat 55 is fixedly connected with the detection column 52, the electromagnets 56 are provided with two, the two electromagnets 56 are located in the mounting box 47, the two electromagnets 56 are fixedly connected with the mounting box 47, the two electromagnets 56 are respectively located directly above the two magnetic blocks 411, the two electromagnets 56 and the sliding rheostat 55 are connected in series, the reset switch 54 is fixedly connected with the detection box 51, and the reset switch 54 is located above the detection column 52.

[0045] The reset switch 54 is a contact switch. When the reset switch 54 is closed, the reset switch 54 sends a signal to the external console, and the external console receives the signal to end the detection of the hole diameter of the workpiece. At this time, the extension ends of the reset cylinder 53, the detection cylinder 45, and the go-no-go gauge cylinder 46 simultaneously begin to return to the original position. When the go gauge unit 43 passes through the hole of the workpiece, the extension ends of the detection cylinder 45 and the go-no-go gauge cylinder 46 continue to extend, and the detection column 52 and the bottom end of the go-no-go gauge 48 simultaneously contact the surface of the workpiece. The extension ends of the detection cylinder 45 and the go-no-go gauge cylinder 46 continue to extend to the set length. In this process, the detection column 52 slides relative to the detection box 51, the extension end of the reset cylinder 53 is compressed, the resistance value of the sliding resistor 55 continuously decreases, the current of the go gauge electromagnet 56 continuously increases, and the magnetic force of the electromagnet 56 increases. When the resistance value of the sliding resistor 55 reaches the preset value, the detection column 52 still slides, but the resistance value of the sliding resistor 55 does not change, that is, the repulsive force of the electromagnet 56 on the magnetic block 411 no longer increases, that is, the force applied by the two go-no-go gauges 48 to the workpiece no longer changes. When the two go-no-go gauges 48 cannot pass through the hole of the workpiece, the two go-no-go gauges 48 slide relative to the mounting box 47, and the extension end of the go-no-go gauge reset cylinder 410 is compressed. When the two go-no-go gauges 48 slide a certain distance, the repulsive force of the electromagnet 56 on the magnetic block 411 is constant, and the two go-no-go gauges 48 continue to slide until the reset switch 54 is closed. At this time, the go-no-go gauge discrimination switch 49 is also closed. In the process of the two go-no-go gauges 48 continuing to slide, the pressure of a single go-no-go gauge 48 on the surface of the workpiece is equal to the sum of the friction between the go-no-go gauge 48 and the mounting box 47 and the size of the repulsive force of the electromagnet 56 on the magnetic block 411. The friction between the go-no-go gauge 48 and the mounting box 47 and the repulsive force of the electromagnet 56 on the magnetic block 411 are constant, that is, the pressure applied by the two go-no-go gauges 48 to the workpiece is always kept constant, preventing the two go-no-go gauges 48 from being forced into the hole of the workpiece due to the increasing pressure, which may cause a false judgment of the hole diameter not meeting the allowable size tolerance range. When the go-no-go gauge 48 is inserted into the hole of the workpiece, in the time period from the opening to the closing of the reset switch 54, the go-no-go gauge 48 cannot slide to the position of closing the go-no-go gauge discrimination switch 49 due to the decreasing or non-existing reaction force of the workpiece on the go-no-go gauge 48. That is, the reset switch 54 is closed, but the go-no-go gauge discrimination switch 49 is not closed. Therefore, the external console determines that the hole diameter of the workpiece does not meet the allowable size tolerance range, and the external console controls the conveying module 3 to convey the workpiece to the unqualified workpiece collection place.

[0046] As Figure 4 and Figure 8As shown, the burr removing module 6 comprises a driving electric cylinder 61, a motor mounting frame 62, a driving motor 63, a fixed plate 64, an adaptive spring 65 and a scraper 66, the driving electric cylinder 61 is located in the cleaning chamber 11, the driving electric cylinder 61 and the workbench 1 are fixedly connected, the output end of the driving electric cylinder 61 and the motor mounting frame 62 are fixedly connected, the driving motor 63 and the fixed plate 64 are both provided with two, the two driving motors 63 and the motor mounting frame 62 are fixedly connected, the output ends of the two driving motors 63 are respectively fixedly connected with one fixed plate 64, the rotation axis of one driving motor 63 falls on the symmetry plane of the corresponding connected one fixed plate 64, the rotation axis of one driving motor 63 coincides with the center axis of the hole to be measured of one workpiece, the rotation axis of the other driving motor 63 falls on the symmetry plane of the corresponding connected other fixed plate 64, the rotation axis of the other driving motor 63 coincides with the center axis of the hole to be measured of the other workpiece, the two sides of the two fixed plates 64 are both provided with the scraper 66, the scraper 66 and the fixed plate 64 are slidingly connected, the adaptive spring 65 is arranged between each scraper 66 and the fixed plate 64, one end of the adaptive spring 65 and the scraper 66 are fixedly connected, the other end of the adaptive spring 65 and the fixed plate 64 are fixedly connected.

[0047] When the burr removing module 6 works, the driving electric cylinder 61 starts, sends the fixed plate 64 into the hole to be measured of the workpiece, and stops working after the scraper 66 reaches the specified position, then the driving motor 63 starts, drives the fixed plate 64 to rotate, under the action of centrifugal force, the adaptive spring 65 is stretched by the scraper 66, the scraper 66 tightly adheres to the inner wall of the hole to be measured of the workpiece under the elastic force of the adaptive spring 65, and removes the burr on the inner wall, after the removal is completed, the driving motor 63 stops working, the adaptive spring 65 pulls back the scraper 66, then the driving electric cylinder 61 starts again, and the fixed plate 64 is collected into the cleaning chamber 11.

At the same time, the visual sensor provided on the go-no-go gauge block is used to directly detect whether the hole diameter of the workpiece to be measured meets the standard, and to detect whether the go-no-go gauge block is working normally. If the detection result of the visual sensor is inconsistent with the detection result of the go-no-go gauge block, the detection result of the visual sensor is used as the reference, and it is determined that the go-no-go gauge block is working abnormally, and the machine needs to be stopped for detection.
