Description

Technical Field

[0001] The present application relates to the technical field of non-metallic precision parts detection, and in particular to a non-metallic precision parts anti-deformation detection device and a method of using the same. Background Art

[0002] With the development of science and technology and the improvement of industrial manufacturing level, non-metallic precision parts are increasingly used in various fields. In order to ensure the stability and reliability of these precision parts during use, anti-deformation detection technology plays a vital role in the non-metallic precision parts manufacturing industry.

[0003] Non-metallic precision parts may be subjected to a variety of different working conditions during use, such as tension or pressure, or both tension and pressure. Anti-deformation detection is achieved through a detection device, which is used to test the pressure or tension of non-metallic precision parts. However, the detection device can generally only perform one of the pressure and tension tests. Different detection requirements require two sets of equipment to achieve, and when pressure and tensile force need to be detected simultaneously, it cannot be achieved, resulting in poor detection efficiency and effect of non-metallic precision parts. Summary of the invention

[0004] In order to improve detection efficiency and detection effect, the present application provides a non-metallic precision part anti-deformation detection device and a method of using the same.

[0005] In the first aspect, the present application provides a non-metallic precision part anti-deformation detection device, which adopts the following technical solution: A non-metallic precision part anti-deformation detection device comprises a frame, two sliding seats, two clamping and stretching mechanisms, an extrusion mechanism, and a detection mechanism. The two sliding seats are slidably arranged on the frame. The two clamping and stretching mechanisms are respectively arranged on the two sliding seats and are used to first clamp and position the non-metallic precision part and then drive the two sliding seats away from each other and stretch the non-metallic precision part. The extrusion mechanism is located between the two sliding seats and is used to extrude the non-metallic precision part. The detection mechanism is electrically connected to the clamping and stretching mechanism and the extrusion mechanism and is used to control the magnitude of the force and to detect the deformation of the non-metallic precision part.

[0006] By adopting the above technical solution, the non-metallic precision parts are placed on the two clamping and stretching mechanisms. The two clamping and stretching mechanisms are started to clamp and position the non-metallic precision parts first. If the tension needs to be detected, the two clamping and stretching mechanisms continue to start to pull the two sliding seats to move, thereby achieving horizontal tension on the non-metallic precision parts. If the pressure needs to be detected, the extrusion mechanism is started to apply downward pressure on the non-metallic precision parts. At the same time, the detection mechanism is used to control the force on the non-metallic precision parts and detect their deformation. When the tension and pressure need to be detected at the same time, the clamping and stretching mechanism and the pressurizing mechanism are started at the same time to perform the detection.

[0007] The clamping and stretching mechanism, the extrusion mechanism and the detection mechanism can realize the needs of pressure and tension detection separately or simultaneously, and the clamping and stretching mechanism can realize tension detection and can also realize the clamping and positioning of non-metallic precision parts during extrusion mechanism detection, thereby greatly improving the convenience of non-metallic precision parts detection process and improving the detection efficiency and detection effect of non-metallic precision parts.

[0008] Optionally, the clamping and stretching mechanism includes: A bearing plate, arranged on the sliding seat; A limit plate is arranged on the upper surface of the clamping plate, and the non-metallic precision parts are placed on the two bearing plates and abut against the limit plate for positioning; The clamping plate is rotatably arranged on the sliding seat through a rotating shaft and extends above the non-metallic precision part and presses against the non-metallic precision part for positioning; The driving assembly is used to first drive the clamping plate to press against the non-metallic precision part and then drive the sliding seat to move, so that the pressure of the clamping plate on the non-metallic precision part increases as the pulling force on the sliding seat increases.

[0009] By adopting the above technical solution, the non-metallic precision parts are placed on two supporting plates and pressed against two limit plates for positioning, and then the driving component drives the two clamping plates to rotate and press against the non-metallic precision parts for positioning, thereby achieving clamping and positioning of the non-metallic precision parts.

[0010] If it is necessary to test the tension, the drive assembly continues to start and drive the two sliding seats away from each other, and at the same time increases the pressure on the non-metallic precision parts. At this time, the non-metallic precision parts are easily moved out from between the clamping plate and the supporting plate, thereby reducing the test effect on the non-metallic precision parts. Therefore, the drive assembly increases the pressure of the clamping plate on the non-metallic precision parts as the tension increases, thereby reducing the probability of the non-metallic precision parts moving out and improving the detection effect; if it is necessary to test the pressure, the drive assembly is used to maintain the position of the non-metallic precision parts, and the pressure is the pressure in the vertical direction, so it will not cause the non-metallic precision parts to move in the horizontal direction. Therefore, the drive assembly can not only clamp the non-metallic precision parts but also apply tension to the non-metallic precision parts, thereby improving the detection efficiency and detection effect.

[0011] Optionally, a driving groove is provided on the sliding seat and located on a side of the rotating shaft away from the bearing plate, and the driving assembly includes: A driving block is slidably disposed on the driving slot and extends to the upper and lower sides of the clamping plate; The pushing column and the pushing block are arranged on the driving block and located at the upper and lower sides of the clamping plate; The telescopic part is rotatably arranged on the frame and the piston rod is rotatably connected to the pushing column and is used to drive the driving block to move. The pushing block moves upward to first push the clamping plate to clamp the non-metallic precision part for positioning and continues to move to drive the sliding seat to move, so that the pressure of the clamping plate on the non-metallic precision part increases with the increase of the pulling force on the sliding seat; the pushing block moves downward away from the clamping plate and makes the piston rod or the pushing column of the telescopic part push the clamping plate away from the non-metallic precision part to achieve unlocking.

[0012] By adopting the above technical solution, when detection is required, the telescopic part starts to drive the push column and the drive block to move, the drive block moves upward to drive the push block upward, the push block moves upward to push the clamping plate to press against the non-metallic precision part for clamping and positioning, if pressure detection is required, the telescopic part is used to maintain the clamping and positioning effect on the non-metallic precision part, and the extrusion mechanism is started to apply downward pressure to the non-metallic precision part.

[0013] When the pull force needs to be detected, the telescopic part continues to start driving the push block upward, and the clamping plate blocks the push block from moving upward, driving the two sliding seats to maintain a tendency to move away from each other, and the force of the push block is dispersed into a pull force for pulling the sliding seat horizontally and a pressure for pushing the clamping plate upward to rotate, and the horizontal pull is converted into a horizontal pull on the non-metallic precision part, and the pressure is applied to the non-metallic precision part, and the pressure of the clamping plate on the non-metallic precision part increases with the increase of the pull. At the same time, after the detection is completed, the return movement of the telescopic part piston rod cancels the force on the sliding seat and the clamping plate, and the non-metallic precision part rests on the limit plate to block the movement of the sliding seat, even if the push block and the push column are both moved downward, the push block is disengaged from the clamping plate, so that the push column or the telescopic part piston rod contacts the clamping plate and pushes the clamping plate away from the non-metallic precision part, thereby unlocking the non-metallic precision part, thereby facilitating the removal of the non-metallic precision part, thereby further greatly improving the convenience during detection, and improving the detection efficiency and detection effect.

[0014] Optionally, the extrusion mechanism includes: An extrusion member is arranged on the frame; The extrusion plate is arranged on the piston rod of the extrusion piece and moves up and down under the action of the extrusion piece and is used to extrude non-metallic precision parts.

[0015] By adopting the above technical solution, the extrusion member starts to drive the extrusion plate to move downward, and the extrusion plate moves downward to apply downward pressure to the non-metallic precision part. After the application is completed, the extrusion member drives the extrusion plate to move upward and separate from the non-metallic precision part.

[0016] Optionally, the detection mechanism includes: A first pressure tester and a second pressure tester are both arranged on the frame and located on one side of the sliding seat and the extrusion plate; A first pressing plate, which is arranged on the sliding seat and pressed against the first pressure tester and is used to detect the pulling force on the non-metal precision part; A second pressing plate, disposed on the extrusion plate and extending above the extrusion plate, the second pressing plate is pressed against the second pressure tester and is used to detect the pressure of the non-metallic precision parts; The detection component is used to detect the deformation of the non-metallic precision parts and is electrically connected to the first pressure tester, the second pressure tester, the telescopic part and the extrusion part.

[0017] By adopting the above technical scheme, a tensile force is applied to the non-metallic precision parts, and the sliding seat and the second pressure plate are both subjected to the tensile force, and this tensile force is converted into pressure on the first pressure tester. The first pressure tester is used to detect the tensile force on the non-metallic precision parts, and when the extrusion plate moves downward, it drives the second pressure plate close to the second pressure tester. The pressure of the extrusion plate on the non-metallic precision parts is converted into the pressure of the second pressure plate on the second pressure tester, which is used to detect the pressure on the non-metallic precision parts. At the same time, the detection component is used to detect the deformation of the non-metallic precision parts, and the detection component also adjusts the tensile force and pressure of the telescopic part and the driving part on the non-metallic precision parts according to the pressure values ​​of the first pressure tester and the second pressure tester, so as to detect the anti-deformation performance of the non-metallic precision parts, thereby improving the detection efficiency and detection effect.

[0018] Optionally, the detection component includes: A detector, which is arranged on the frame and is used to detect deformation of non-metallic precision parts; A controller, electrically connected to the detector and receiving the detection data of the first pressure tester and the second pressure tester and controlling the start and stop of the telescopic member and the extrusion member and the magnitude of the force according to the data; The display is arranged on the rack and electrically connected to the controller and is used to display the data of the controller.

[0019] By adopting the above technical solution, the detector is used to detect the deformation of non-metallic precision parts and transmit the detection data to the controller for processing. The controller is used to control the start and stop of the driving part and the extrusion part and the size of the force, so that the detection time and frequency can be designed according to needs, and different forces can be adjusted to detect non-metallic precision parts, thereby further improving the detection efficiency and detection effect.

[0020] Optionally, a sliding frame is provided on the frame for sliding movement in a direction perpendicular to the sliding direction of the sliding seat, a moving component for driving the sliding frame to move is provided on the frame, and the extrusion mechanism is provided on the sliding frame.

[0021] By adopting the above technical solution, the moving component starts to drive the sliding member and the extrusion mechanism to move, so that the extrusion mechanism can detect different positions, especially can perform pressure detection on larger non-metallic precision parts, thereby further improving the detection effect.

[0022] Optionally, the mobile component includes: A movable lead screw is rotatably arranged on the frame and threadably connected to the sliding frame; The moving motor is arranged on the frame and the output shaft is connected with the moving lead screw.

[0023] By adopting the above technical solution, the moving motor starts to drive the moving screw to rotate, and the moving screw rotates to drive the sliding frame to move.

[0024] Optionally, a flaw detection component is provided on the sliding frame, and the flaw detection component includes: The flaw detection seat is slidably arranged on the sliding frame and the sliding direction is perpendicular to the sliding direction of the sliding frame; Moving parts, used to drive the flaw detection seat to move; The detection piece is arranged on the flaw detection seat and reciprocates under the action of the moving piece and the moving assembly to detect the surface cracks of the non-metal precision parts.

[0025] By adopting the above technical solution, when a force is applied to a non-metallic precision part, the detection component is located outside the non-metallic precision part for detection, and a complete detection of the surface of the non-metallic precision part cannot be achieved. The detection area is small, thereby reducing the detection effect of the deformation of the non-metallic precision part. The moving part drives the flaw detection seat and the detection part to move, and the moving component drives the sliding frame and the detection part to move, thereby driving the detection part to move in two mutually perpendicular directions. The detection part detects cracks on the surface of non-metallic precision parts, and cooperates with the detection component to further detect the deformation of non-metallic precision parts, thereby increasing the detection area and further improving the detection effect.

[0026] In the second aspect, the present application provides a detection method using the following technical solution: A detection method comprises the following steps: Unloading: Place the non-metallic precision parts on two load-bearing plates and position them against two limit plates; Detection: The controller starts to detect, and the two telescopic parts start to drive the two clamping plates to clamp the non-metallic precision parts for clamping and positioning; a. Tension test: The two telescopic parts continue to start to drive the two sliding seats away from each other, and the first pressure tester is used to detect the horizontal tension on the non-metallic precision parts; b. Pressure detection: The extrusion member drives the extrusion plate to move downward to extrude the non-metallic precision member, and the second pressure tester detects the vertical pressure on the non-metallic precision member. Steps a and b are started separately or simultaneously as needed, and the detection data is displayed on the display. At the same time, the magnitude of the force and the detection time are adjusted as needed to re-detect; Conclusion: The anti-deformation performance of non-metallic precision parts is obtained based on the test data.

[0027] By adopting the above technical scheme, the non-metallic precision parts are placed on two supporting plates and rest against two limit plates for positioning; the controller is started for detection, and the two telescopic parts are started to drive the two clamping plates to clamp the non-metallic precision parts for clamping and positioning; if tension detection is required, the two telescopic parts continue to start to drive the two sliding seats away from each other, and the first pressure tester is used to detect the horizontal tension on the non-metallic precision parts; if pressure detection is required, the extrusion part drives the extrusion plate to move downward to extrude the non-metallic precision parts, and the second pressure tester detects the vertical pressure on the non-metallic precision parts. The tension and pressure detection are started separately or simultaneously as required, and the anti-deformation performance of the non-metallic precision parts is obtained according to the detection data, thereby improving the detection efficiency and detection effect.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: The clamping and stretching mechanism, the extrusion mechanism and the detection mechanism can realize the needs of pressure and tension detection separately or simultaneously, and the clamping and stretching mechanism can realize tension detection and can also realize the clamping and positioning of non-metallic precision parts during extrusion mechanism detection, thereby greatly improving the convenience of non-metallic precision parts detection process and improving the detection efficiency and detection effect of non-metallic precision parts.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a non-metallic precision part anti-deformation detection device.

[0033] Reference Figure 1 The non-metallic precision parts anti-deformation detection device includes a frame 1, two sliding seats 11, two clamping and stretching mechanisms 2, an extrusion mechanism 5 and a detection mechanism 6. The two sliding seats 11 are horizontally slidably arranged on the frame 1, and the two clamping and stretching mechanisms 2 are respectively arranged on the two sliding seats 11. The two clamping and stretching mechanisms 2 first clamp and position the non-metallic precision parts and then drive the two sliding seats 11 away from each other, so as to achieve horizontal pulling force on the non-metallic precision parts; the extrusion mechanism 5 is located between the two sliding seats 11, and is used to extrude the non-metallic precision parts, so as to achieve vertical pressure on the non-metallic precision parts; the detection mechanism 6 is electrically connected to the clamping and stretching mechanism 2 and the extrusion mechanism 5, and the detection mechanism 6 is used to control the start and stop of the stretching mechanism 2 and the extrusion mechanism 5 and control the size of the force, so as to achieve the detection of the deformation amount of the non-metallic precision parts.

[0034] Reference Figure 1 and Figure 2 The two clamping and stretching mechanisms 2 are arranged corresponding to the two sliding seats 11 and drive the two sliding seats 11 to move closer to or away from each other. The clamping and stretching mechanism 2 includes a bearing plate 21, a limiting plate 22, a clamping plate 23, and a driving assembly 3. The two bearing plates 21 are fixedly mounted on the opposite side walls of the two sliding seats 11 and are in a horizontal state. The limiting plate 22 is fixedly mounted on the upper surface of the bearing plate 21 and is located close to the side of the sliding seat 11. The limiting plate 22 is in a horizontal state. The non-metallic precision parts are placed on the upper surfaces of the two bearing plates 21 and are positioned against the two limiting plates 22. The upper surface of the non-metallic precision parts extends above the limiting plate 22.

[0035] A horizontal rotating shaft 12 is fixedly installed on the side wall of the sliding seat 11 adjacent to the supporting plate 21. The clamping plate 23 includes a clamping portion 24 and a rotating portion 25. The rotating portion 25 is rotatably installed on the rotating shaft 12, and the clamping portion 24 is integrally arranged on one end of the rotating portion 25 close to the supporting plate 21. The clamping portion 24 is located above the non-metallic precision part. The rotating portion 25 rotates to drive the clamping portion 24 to press against the non-metallic precision part for clamping and positioning.

[0036] The driving assembly 3 is used to first drive the clamping plate 23 to press against the non-metallic precision part and then drive the sliding seat 11 to move, and the pressure of the clamping plate 23 on the non-metallic precision part gradually increases as the pulling force on the sliding seat 11 increases. The sliding seat 11 is installed on the side wall of the rotating shaft 12 and is provided with a driving groove 13 on the side of the rotating shaft 12 away from the bearing plate 21. The driving groove 13 can be in a vertical state, or the driving groove 13 is in an inclined state. The horizontal distance between the bottom end of the driving groove 13 and the bearing plate 21 is smaller than the horizontal distance between the top end and the bearing plate 21. The end of the rotating part 25 away from the clamping part 24 passes through one side of the driving groove 13.

[0037] The driving assembly 3 includes a driving block 31, a pushing column 32, a pushing block 33, and a telescopic member 34. The driving block 31 is slidably installed on the driving groove 13 up and down, and the side wall of the driving block 31 away from the bottom of the driving groove 13 is flush with the side wall of the sliding seat 11; the pushing column 32 and the pushing block 33 are fixedly installed on the side wall of the driving block 31 away from the bottom of the driving groove 13, and the axis of the pushing column 32 is parallel to the axis of the rotating shaft 12 and is located above the rotating part 25, and the driving block 31 is located below the rotating part 25; the telescopic member 34 is an electric push rod or an oil cylinder, etc., the cylinder body of the telescopic member 34 is rotatably installed on the frame 1, and the piston rod of the telescopic member 34 is tilted downward and rotatably connected to the pushing column 32, and the telescopic member 34 is used to drive the pushing column 32 to pull the driving block 31 to move on the driving groove 13; the friction between the driving block 31 and the driving groove 13 is less than the friction between the sliding seat 11 and the frame 1, so that the movement of the piston rod of the telescopic member 34 will first drive the pushing column 32 and the driving block 31 to move.

[0038] The piston rod of the telescopic member 34 contracts and drives the push column 32, the drive block 31 and the push block 33 to move upward. The push block 33 moves upward and pushes the rotating part 25 and the clamping part 24 to rotate, so that the clamping part 24 presses against the non-metallic precision part, thereby clamping and positioning the non-metallic precision part. If it is necessary to detect the pressure, the telescopic member 34 maintains the clamping state of the non-metallic precision part, and the extrusion mechanism 5 starts to apply pressure to the non-metallic precision part; if it is necessary to detect the tension, the telescopic member 34 continues to contract, and the upward force of the push block 33 is decomposed into two forces, one drives the two sliding seats 11 to keep moving away from each other and apply a horizontal tension to the non-metallic precision part, and the other drives the clamping part 24 to increase the pressure on the non-metallic precision part, so that the pressure of the clamping part 24 on the non-metallic precision part gradually increases with the increase of the horizontal tension on the non-metallic precision part.

[0039] When the pulling force is applied, the piston rod of the telescopic member 34 extends, releasing the pulling force on the two sliding seats 11 and the non-metallic precision parts, and then the piston rod of the telescopic member 34 continues to extend, and the limit plate 22 abuts against the non-metallic precision parts to block the movement of the two sliding seats 11, that is, the pushing column 32, the driving block 31 and the pushing block 33 are all pushed downward, so that the pushing column 32 or the piston rod of the telescopic member 34 contacts the rotating part 25 and drives it to rotate, so that the clamping part 24 moves upward away from the non-metallic precision parts, thereby unlocking the non-metallic precision parts, and then the non-metallic precision parts can be removed, which improves the convenience of the detection process and improves the detection efficiency and detection effect.

[0040] Reference Figure 1 A sliding frame 14 is slidably installed on the frame 1 and located outside the two clamping and stretching mechanisms 2. The sliding frame 14 extends to above the non-metallic precision parts and the sliding seat 11 located on the bearing plate 21, and the sliding direction of the sliding frame 14 is perpendicular to the sliding direction of the sliding seat 11. A moving component 4 for driving the sliding frame 14 to move is provided on the frame 1; the moving component 4 includes a moving screw rod 41 and a moving motor 42. The moving screw rod 41 is rotatably installed on the frame 1 and is threadedly connected to the sliding frame 14.

[0042] The detection mechanism 6 includes a pressure tester 62, a first pressure plate 63, a second pressure plate 64 and a detection assembly. Two mounting seats 15 are fixedly installed on the frame 1 at intervals along the sliding direction of the sliding seat 11, and the two sliding seats 11 are located between the two mounting seats 15 and outside the two mounting seats 15; two first pressure testers 61 are provided and fixedly installed on the side walls on the opposite side of the two mounting seats 15; the second pressure tester 62 is fixedly installed on the side wall of the sliding frame 14 and is located above the extrusion plate 52.

[0043] Two first pressure plates 63 are provided and fixedly mounted on the side walls of the two sliding seats 11, and the two first pressure plates 63 are located between the two first pressure testers 61. The two first pressure plates 63 are respectively pressed against the two first pressure testers 61 and are used to display the magnitude of the horizontal pulling force applied to the non-metallic precision parts. A vertically upward extrusion rod 16 is fixedly mounted on the upper surface of the extrusion plate 52, and the second pressure plate 64 is fixedly mounted on the top of the extrusion rod 16 and extends horizontally to above the second pressure tester 62. The extrusion plate 52 moves downward to drive the second pressure plate 64 to press against the second pressure tester 62. The second pressure tester 62 is used to detect the pressure of the extrusion plate 52 on the non-metallic precision parts.

[0044] The detection component is used to detect the deformation of non-metallic precision parts and is electrically connected to the first pressure tester 61, the second pressure tester 62, the telescopic part 34 and the extrusion part 51; the detection component includes a detector, a controller and a display. The detector is fixedly mounted on the frame 1 and is directed toward the non-metallic precision parts for detection. It is used to detect the deformation of the non-metallic precision parts and convert the detected signals into electrical signals. The detector can be an infrared detector or other instrument that can detect the deformation.

[0045] The controller is fixedly mounted on the frame 1, and the pressure data detected by the first pressure tester 61 and the second pressure tester 62 are also transmitted to the controller for processing. Then the controller controls the start and stop and running time of the telescopic member 34, the extruding member 51 and the moving motor 42 according to the pressure data, so that the detection frequency and time can be controlled as needed, thereby improving the detection efficiency and detection effect. The display is fixedly mounted on the frame 1 and electrically connected to the controller, and the display is used to display the data in the controller.

[0046] Reference Figure 1A flaw detection assembly 7 is provided on the sliding frame 14. A horizontal fixed rod 17 is fixedly installed on the sliding frame 14 and located on one side of the extrusion member 51 and the extrusion plate 52. The fixed rod 17 is located above the two sliding seats 11 and the two clamping and stretching mechanisms 2; the flaw detection assembly 7 includes a flaw detection seat 71, a moving member 72 and a detection member 73. The flaw detection seat 71 is horizontally slidably installed on the fixed rod 17, and the sliding direction of the flaw detection seat 71 is parallel to the sliding direction of the sliding seat 11; the moving member 72 is an electric push rod, the moving member 72 is fixedly installed on the sliding frame 14 and the piston rod is fixedly connected to the flaw detection seat 71, and the moving member 72 is used to drive the flaw detection seat 71 to move.

[0047] The detection part 73 is fixedly mounted on the lower surface of the flaw detection seat 71, and the detection part 73 is used to detect surface cracks of non-metallic precision parts. The detection part 73 can be an infrared detector, or the detection part 73 is an eddy current detection probe. Therefore, before the force is applied to the non-metallic precision parts, a layer of metal particle coating is brush-plated on the upper surface of the non-metallic precision parts. After the force is applied, it is used to detect cracks on the metal particle coating layer, thereby realizing the detection of the anti-deformation performance of the non-metallic precision parts and improving the detection effect.

[0048] The working principle of the embodiment of the present application is as follows: The non-metallic precision parts are placed on the two supporting plates 21 and rest against the limit plates 22 for positioning. The piston rods of the two telescopic parts 34 are simultaneously contracted to drive the two clamping parts 24 to press against the non-metallic precision parts for clamping and positioning. If pressure needs to be applied, the extrusion part 51 drives the extrusion plate 52 to move downward to apply downward pressure to the non-metallic precision parts. The first pressure tester 61 detects the pressure, and the detector is used to detect the deformation of the non-metallic precision parts. The extrusion part 51 drives the extrusion plate 52 to move upward. If pulling force needs to be applied, the piston rod of the telescopic part 34 continues to retract to apply horizontal pulling force to the non-metallic precision parts, and increases the pressure of the clamping plate 23 on the non-metallic precision parts. The second pressure tester 62 detects the pulling force, and the detector detects the deformation of the non-metallic precision parts. Therefore, the pressure and pulling force of the non-metallic detector are detected separately or simultaneously as needed, thereby improving the detection efficiency and effect.

[0049] The moving member 72 drives the detecting member 73 to move, and at the same time, the moving motor 42 drives the detecting member 73 to move in another direction, thereby realizing driving the detecting member 73 to move in two mutually perpendicular directions. The detecting member 73 is used to detect cracks on the upper surface of non-metallic precision parts. At the same time, the moving motor 42 can also start to adjust the position of the extrusion plate 52, so that the extrusion plate 52 can adapt to applying pressure to non-metallic precision parts of larger sizes, thereby further improving the detection effect.

[0050] The embodiment of the present application discloses a detection method.
