Description

Technical Field

[0001] The present invention relates to the technical field of gasket detection, and in particular to a strength detection device and a detection method for an octagonal gasket. Background Art

[0002] Octagonal gasket is a solid metal gasket with an octagonal cross-section made of metal material by forging, heat treatment and machining. It has radial self-tightening sealing effect and is a standard R-type metal ring gasket. Its working principle is to rely on the contact between the gasket and the inner and outer surfaces (mainly the outer side) of the flange trapezoidal groove, and to form a sealing effect by pressing. The octagonal metal ring gasket is installed in the trapezoidal ring groove of the flange surface. When the connecting bolts are tightened, it is axially compressed and close to the upper and lower trapezoidal grooves, resulting in plastic deformation, forming an annular sealing belt, and establishing an initial seal. After the pressure is increased, the ring gasket expands radially under the action of the medium pressure. The gasket is more closely attached to the inclined surface of the trapezoidal groove, producing a self-tightening effect. However, the increase in medium pressure will also cause the flange and the connecting bolts to deform, resulting in relative separation between the sealing surfaces, and the gasket sealing ratio is relatively reduced. Therefore, the ring gasket can be considered as a semi-self-tightening seal. When producing octagonal gaskets, in order to ensure its stability during use, the hardness of the octagonal gasket needs to be tested.

[0003] A Chinese patent document with authorization announcement number CN215985488U discloses a hardness detection device for the production of corrugated tooth gaskets. The hardness detection device for the production of corrugated tooth gaskets, by setting a transposition mechanism, can, after the gasket is sleeved on the outside of the positioning shaft, the pressing needle descends and the needle tip presses the top of the gasket inside the rightmost placement slot, the pressing needle resets, and the motor shaft of the stepper motor drives the placement plate to rotate, so that the adjacent placement slot rotates to the rightmost side, and the needle tip of the pressing needle presses the gasket inside the placement slot, and so on, so that the pressing needle presses the gaskets in turn, thereby improving the detection efficiency of the gasket samples.

[0004] However, the structural design of the above-mentioned related technology: although it can detect multiple gaskets, it can only detect one point on a single side of the gasket during detection, which is inconvenient to detect multiple positions of the gasket and cannot fully reflect the hardness of the material, which will affect the detection accuracy of the gasket hardness.

[0005] Therefore, a strength detection device and a detection method for an octagonal gasket are proposed to solve the above-mentioned problems. Summary of the invention

[0006] The present invention provides an octagonal gasket strength detection device and a detection method thereof, aiming to solve the problem in the related art that it is inconvenient to detect multiple positions of the gasket, thereby affecting the detection accuracy of the gasket hardness.

[0007] The strength detection device and detection method of the octagonal gasket of the present invention include a detection mechanism and a driving mechanism, wherein the detection mechanism is used to detect the hardness of the gasket, and a plurality of clamping mechanisms are slidably arranged on the driving mechanism, and the driving mechanism can drive the clamping mechanisms to rotate;

[0008] The detection mechanism includes a body, a pressure head mounted on the body, and a rotating assembly located on one side of the pressure head. A placement plate is provided on the inner bottom wall of the body, and the placement plate can be raised and lowered along the height direction of the body to drive the gasket to approach the pressure head.

[0009] The clamping mechanism includes a rotating shaft slidably arranged on the driving mechanism, a slide mounted on the rotating shaft, and a clamping ring rotatably connected to the slide for clamping the gasket. The rotating shaft can drive the slide to rotate. The driving mechanism drives the gasket to move to the placement disk through the slide. The placement disk moves up and drives the gasket close to the pressure head to detect the gasket. After detecting one point of the gasket, the rotating assembly drives the clamping ring to rotate to detect other positions on the gasket. After detecting one end of the gasket, the rotating shaft drives the gasket to rotate around the rotating shaft through the slide to detect the other end of the gasket.

[0010] Beneficial effect: the gasket is clamped in multiple clamping rings in sequence, and then the driving mechanism drives the gasket in the clamping ring to move to the placement disk through the slide, and the gasket is driven close to the pressure head by moving the placement disk upward to detect one end of the gasket. After the pressure head detects one point of the gasket, the rotating assembly drives the clamping ring to rotate to detect other positions on the gasket to achieve the effect of multi-point detection. After detecting one end of the gasket, the placement disk is reset, and then the driving mechanism drives the undetected gasket to move to the placement disk to continuously detect the gasket. In the process of detecting other gaskets, the rotating shaft drives the detected gasket to rotate around the rotating shaft through the slide, so that the undetected end of the gasket faces upward, and when the detected gasket moves to the placement disk again, the pressure head detects the other end of the gasket.

[0011] Preferably, a dustproof mechanism is provided on the inner side of the driving mechanism, and the dustproof mechanism includes a dust cover, a base plate and two connecting covers, the base plate is installed at the bottom end of the dust cover, the two connecting covers are symmetrically installed at the top and bottom ends of the dust cover and are connected with the dust cover, a limiting groove is provided on the inner side of the dust cover, the slide plate is slidably arranged in the limiting groove, and grooves are provided on the inner bottom wall and the inner top wall of the limiting groove, and the groove is located between the two connecting covers.

[0013] The effect is that when the gasket approaches the pressure head, the rotating shaft leaves the slide groove and enters the annular groove, so that the rotating shaft cannot contact the rotating column, avoiding the vibration on the rotating column from being transmitted to the gasket, thereby further improving the detection accuracy of the gasket.

[0014] Preferably, a slider is rotatably connected to the rotating shaft, and the slider is slidably connected in the slide groove. A gear 1 is installed on the outer side of the rotating shaft, and a rack is installed on the bottom plate, and the gear 1 can mesh with the rack.

[0015] The effect is that, through the coordinated arrangement of the gear 1 and the rack, the slide plate can be driven to rotate around the rotating shaft during the movement of the slide plate, so as to exchange the two ends of the gasket.

[0016] Preferably, a mounting seat is installed on the skateboard, and the mounting seat is rotatably connected to gear two, the clamping ring is installed on gear two, one side of gear two is meshingly connected to gear three, a limiting sleeve is installed on gear three, the limiting sleeve is rotatably connected to the mounting seat, and the rotating assembly can drive the limiting sleeve to rotate.

[0017] Preferably, the rotating assembly includes a transverse plate, a fixed rod, a pressure ring and a limit shaft, the transverse plate is installed on the machine body, the fixed rod is installed at the bottom of the transverse plate, the pressure ring is installed on the fixed rod, the limit shaft is located on the inner side of the pressure ring, and a motor 1 is installed on the top of the transverse plate, the motor 1 is connected to the limit shaft, and the limit shaft can be inserted into the limit sleeve.

[0018] The effect is that after the pressure head squeezes the gasket once, the limit shaft drives gear three to rotate through the limit sleeve, and gear three drives the gasket in the clamping ring to rotate through gear two to change the position of the gasket, so that the pressure head can detect different positions of the gasket.

[0019] Preferably, a grinding mechanism and a polishing mechanism are provided at the bottom end of the dust cover, and the grinding mechanism and the polishing mechanism have the same structure so as to grind and polish the gasket. A cleaning mechanism is provided at the top end of the dust cover so as to clean the gasket. The polishing mechanism is located on one side of the connecting cover, and the cleaning mechanism is located on the other side of the connecting cover.

[0020] The effect is that the gasket can be ground, polished and cleaned in sequence through the grinding mechanism, the polishing mechanism and the cleaning mechanism to remove impurities and oxide layers on the gasket and avoid affecting the hardness detection of the gasket.

[0021] Preferably, the grinding mechanism includes a mounting cylinder, a lifting seat and a cleaning piece, the mounting cylinder is mounted at the bottom end of the dust cover and is connected to the dust cover, the lifting seat is located inside the mounting cylinder and can be lifted and lowered along the height direction of the mounting cylinder, and the cleaning piece is arranged in the lifting seat and can rotate around itself.

[0022] Preferably, a water inlet pipe is installed on the top of the dust cover, and the water inlet pipe is located above the lifting seat.

[0023] The strength detection method of the octagonal gasket of the present invention uses the strength detection device of the octagonal gasket, and comprises the following steps:

[0024] S1: clamping the gaskets in a plurality of clamping mechanisms in sequence and driving the gaskets on the clamping mechanisms to move through the driving mechanisms;

[0025] S2: During the movement of the gasket, the grinding mechanism and the polishing mechanism grind and polish the bottom end of the gasket in turn. When the gasket enters the connection cover, the gear 1 meshes with the rack. At this time, the shaft drives the gasket to rotate around the shaft through the slide plate, so that the bottom end of the gasket faces upward. When the gasket moves to the cleaning mechanism, the cleaning mechanism wipes the water on the gasket;

[0026] S3: When the gasket moves to the placement plate, the placement plate drives the gasket to move upward, so that the gasket is close to the pressure head, and the limit shaft is inserted into the limit sleeve at the same time;

[0027] S4: During the inspection, the pressure head presses the gasket. After the pressure head presses a point, the limit shaft drives the limit sleeve to rotate, thereby driving the gasket to rotate, so that the pressure head detects other positions on the gasket;

[0028] S5: After one end of the gasket is inspected, the inspected gasket enters the dust cover again, and the other end of the gasket is ground, polished and cleaned to inspect the other end of the gasket.

[0029] Beneficial effect: the gasket is clamped in multiple clamping mechanisms in sequence, and then the driving mechanism drives the gasket to move to the placement disk through the clamping mechanism, and the gasket is driven close to the pressure head by moving the placement disk upward to detect one end of the gasket. After the pressure head detects one point of the gasket, the rotating assembly drives the clamping ring to rotate to detect other positions on the gasket. After detecting one end of the gasket, the rotating shaft drives the detected gasket to rotate around the rotating shaft through the slide plate, so that the undetected end of the gasket faces upward. When the detected gasket is moved to the placement disk again, the pressure head detects the other end of the gasket, thereby realizing double-sided and multi-point detection of the gasket, which can more comprehensively reflect the hardness of the gasket.

[0030] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: the gasket is clamped in multiple clamping rings in sequence, and then the gasket is driven to move to the placement disk through the driving mechanism, and the gasket is driven to approach the pressure head by moving the placement disk upward to detect one end of the gasket. After the pressure head detects one point of the gasket, the rotating assembly drives the clamping ring to rotate to detect other positions on the gasket to achieve the effect of multi-point detection. After detecting one end of the gasket, the placement disk is reset, and then the driving mechanism drives the undetected gasket to move to the placement disk to continuously detect the gasket. In the process of detecting other gaskets, the rotating shaft drives the detected gasket to rotate around the rotating shaft through the slide plate, so that the undetected end of the gasket faces upward. When the detected gasket is moved to the placement disk again, the pressure head detects the other end of the gasket, thereby realizing double-sided multi-point detection of the gasket, which can more comprehensively reflect the hardness of the gasket and avoid affecting the detection accuracy of the gasket hardness.

During the detection, the gasket is first placed in the clamping mechanism 40 for clamping, and then the driving mechanism 30 drives the gasket in the clamping mechanism 40 to pass through the grinding mechanism 50, the polishing mechanism 60 and the cleaning mechanism 70 in sequence, so that the gasket is sequentially ground, polished and cleaned, and finally the driving mechanism 30 drives the gasket to move to the detection mechanism 10 for detection.

[0048] like Figure 1 and Figure 2As shown, the detection mechanism 10 includes a body 11, a pressure head 12, a rotating assembly 13, a lifting column 14, a placement plate 15 and a supporting plate 16.

The lifting column 14 can drive the placement plate 15 to rise and fall so that the gasket is close to the pressure head 12, and the supporting plate 16 is mounted on the outside of the placement plate 15.

[0049] like Figure 2 As shown, the rotating assembly 13 includes a transverse plate 131, a fixed rod 132, a pressure ring 133 and a limit shaft 135. The transverse plate 131 is mounted on the inner top wall of the body 11, and the fixed rod 132 is mounted on the bottom side of the transverse plate 131. There are multiple fixed rods 132. In this embodiment, the number of fixed rods 132 is four. In other embodiments, the number of fixed rods 132 is two, six or more even numbers. The pressure ring 133 is mounted on the bottom ends of the multiple fixed rods 132, and the limit shaft 135 is located on the inner side of the pressure ring 133. A motor 134 is installed on one side of the top of the transverse plate 131. The driving shaft of the motor 134 is installed on the top of the limit shaft 135. The limit shaft 135 is an external spline shaft, and the limit shaft 135 can be driven to rotate by the motor 134.

The dust cover 21 is annular in shape, and the base plate 22 is installed at the bottom end of the dust cover 21. The two connecting covers 29 are both fan-shaped in shape. The two connecting covers 29 are symmetrically installed at the top and bottom ends of the dust cover 21 and are connected to the dust cover 21 to increase the depth of the dust cover 21. The connecting cover 29 is located between the polishing mechanism 60 and the cleaning mechanism 70.

[0051] A limit groove 24 is provided on the inner side of the dust cover 21, and the clamping mechanism 40 is slidably arranged in the limit groove 24. A groove 25 is provided on the inner bottom wall and the inner top wall of the limit groove 24. The groove 25 is located between the two connecting covers 29 for the clamping mechanism 40 to rotate. A rack 23 is installed on the top of the bottom plate 22 near the groove 25. The rack 23 is in an arc shape and can be engaged with the clamping mechanism 40. When the driving mechanism 30 drives the clamping mechanism 40 to rotate, the bottom end of the gasket is grinded and polished in turn. When the clamping mechanism 40 is engaged with the rack 23, the clamping mechanism 40 can be driven to rotate under the action of the rack 23, so that the polished surface of the gasket faces upward, so as to facilitate the detection of the gasket. After one end of the gasket is detected, the gasket continues to move. At this time, under the action of the rack 23, the other side of the gasket can be detected, so as to accurately reflect the overall hardness of the gasket.

[0052] A detection slot 27 is provided at the top of the dust cover 21, and the placement plate 15 is located inside the detection slot 27. A hole is provided on the inner bottom wall of the detection slot 27 for the lifting column 14 to pass through. A through slot 26 connected to the limit slot 24 is provided on the top of the dust cover 21 near the detection slot 27, so as to allow the clamping mechanism 40 to pass through. Dust curtains 28 are installed on both sides of the inner top wall of the dust cover 21 near the detection slot 27 to prevent dust from entering. A feeding hole is provided on the top of the dust cover 21 near the detection slot 27 to place the gasket into the clamping mechanism 40.

[0053] When the driving mechanism 30 drives the clamping mechanism 40 to move into the detection slot 27, the gasket in the clamping mechanism 40 is located at the top of the placement plate 15. At this time, the lifting column 14 drives the clamping mechanism 40 and the gasket to move upward through the placement plate 15, so that the gasket is close to the pressure head 12, and the pressure ring 133 is pressed on the clamping mechanism 40.

[0054] like Figure 1 , Figure 3 and Figure 4 As shown, the driving mechanism 30 includes a support frame 31, a second motor 32 and a rotating column 33.

The second motor 32 can drive the rotating column 33 to rotate, thereby driving the multiple clamping mechanisms 40 to rotate.

[0055] A plurality of slide grooves 34 are provided on the outer side of the rotating column 33. The plurality of slide grooves 34 are distributed in a circular array with the axis of the rotating column 33 as the center. The shape of the slide groove 34 is T-shaped. The clamping mechanism 40 is slidably connected to the slide groove 34. The number of the slide grooves 34 is the same as that of the clamping mechanism 40. An annular groove 35 connected to the slide groove 34 is provided on the outer side of the top end of the rotating column 33. The depth of the annular groove 35 is greater than the depth of the slide groove 34. When the pressure ring 133 is pressed on the clamping mechanism 40, the clamping mechanism 40 is separated from the slide groove 34 and enters the annular groove 35 to prevent the vibration generated by the operation of the grinding mechanism 50, the polishing mechanism 60 and the cleaning mechanism 70 from being transmitted to the clamping mechanism 40, thereby ensuring the detection accuracy of the gasket.

[0056] like Figures 1 to 5As shown, the clamping mechanism 40 includes a slide plate 41, a rotating shaft 42, a gear 1 43, a slider 44, a mounting seat 45, a gear 2 46, a clamping ring 47, a gear 3 48 and a limiting sleeve 49. The rotating shaft 42 is mounted on one end of the slide plate 41, and the other end of the slide plate 41 extends into the dust cover 21. The slide plate 41 is rectangular in shape and is located in the limiting groove 24.

[0057] The mounting seat 45 is composed of a cylinder and an arc seat. The second gear 46 is rotatably connected in the arc seat of the mounting seat 45. The top and bottom ends of the second gear 46 are provided with annular guide grooves. The arc seat of the mounting seat 45 is provided with a stopper block adapted to the guide groove. A clamping ring 47 is installed on the inner side of the second gear 46. The clamping ring 47 is located on the outer side of the mounting seat 45. A clamping plate is provided on the inner side of the clamping ring 47 to clamp the gasket. The third gear 48 meshes with the second gear 46. The third gear 48 is installed on the outer side of the stopper sleeve 49. The bottom end of the stopper sleeve 49 is rotatably connected to the inner bottom wall of the cylinder of the mounting seat 45. In this embodiment, the limit sleeve 49 is an internal spline shaft, and a hole for inserting the limit shaft 135 is opened at the top of the cylinder of the mounting seat 45, so that the limit shaft 135 can be inserted into the limit sleeve 49. The rotation of the limit shaft 135 can drive the gear three 48 on the limit sleeve 49 to rotate. At the same time, the gear three 48 can drive the gasket in the clamping ring 47 to rotate through the gear two 46 to change the position of the gasket, so that the pressure head 12 is pressed on different positions of the gasket, so that different positions of the gasket can be detected to more accurately reflect the hardness of the gasket.

[0058] The gasket can be clamped by the clamping ring 47 so that the top and bottom ends of the gasket can extend out of the gear 2 46, and then the motor 2 32 drives the slide plate 41 to rotate around the rotating column 33 through the slider 44 in the rotating column 33. When the gasket moves to the top of the grinding mechanism 50, the bottom end of the gasket is ground by the grinding mechanism 50. When the gasket moves to the top of the polishing mechanism 60, the polishing mechanism 60 polishes the bottom end of the gasket. When the gasket enters the connecting cover 29, the gear 1 43 meshes with the rack 23. At this time, the rotating column 33 continues to rotate. Under the action of the rack 23, the rotating shaft 42 drives the gasket to rotate through the slide plate 41, so that the bottom end of the gasket faces upward. When the gasket moves to the bottom of the cleaning mechanism 70, the cleaning mechanism 70 wipes the polished surface of the gasket to ensure the cleanliness of the detection surface.

[0059] like Figure 1 , Figure 2 and Figure 6As shown, the grinding mechanism 50 and the polishing mechanism 60 have the same structure, and the grinding mechanism 50 includes a mounting tube 51, a lifting seat 55, a motor 3 56 and a cleaning member 57. The mounting tube 51 is mounted at the bottom end of the dust cover 21 and is connected to the dust cover 21, the lifting seat 55 is located inside the mounting tube 51, the motor 3 56 is mounted at the bottom end of the lifting seat 55, the cleaning member 57 is located inside the lifting seat 55, and the driving shaft of the motor 3 56 is mounted at the bottom end of the cleaning member 57. The cleaning member 57 in the grinding mechanism 50 is a grinding wheel, and the cleaning member 57 in the polishing mechanism 60 is a polishing wheel.

[0060] A telescopic member 52 is installed at the bottom end of the mounting tube 51. In the present embodiment, the telescopic member 52 is a cylinder. In other embodiments, the telescopic member 52 is a hydraulic cylinder or an electric telescopic rod. The movable end of the telescopic member 52 passes through the mounting tube 51 and extends to the inside of the mounting tube 51. A connecting plate 53 is installed on the movable end of the telescopic member 52. Two connecting rods 54 are installed on the top of the connecting plate 53. The two connecting rods 54 are both installed at the bottom end of the lifting seat 55. The motor three 56 is located between the two connecting rods 54.

[0061] like Figure 2 and Figure 6 As shown, a water inlet pipe 59 is installed at the top of the dust cover 21, and the water inlet pipe 59 is located above the lifting seat 55. The end of the water inlet pipe 59 is connected to an external water pump to add water to the lifting seat 55 to prevent dust from being generated during grinding or polishing. A plurality of drainage grooves 58 are provided on the edge of the inner bottom wall of the lifting seat 55 to drain the water in the lifting seat 55 into the mounting tube 51. A drainage pipe is installed at the bottom of one side of the mounting tube 51 to drain the water in the mounting tube 51.

[0062] When grinding or polishing the gasket, the motor 3 56 drives the cleaning part 57 to rotate, and at the same time the water inlet pipe 59 continuously adds water to the lifting seat 55, and then the telescopic part 52 drives the lifting seat 55 to move upward through the connecting rod 54 on the connecting plate 53, so that the cleaning part 57 contacts with the gasket to grind or polish the gasket to prevent impurities and oxide layer on the gasket from affecting the detection of the gasket.

[0063] like Figure 1 , Figure 2 and Figure 7 As shown, the cleaning mechanism 70 includes a motor 71 and a cleaning disc 72. The motor 71 is installed at the top of the dust cover 21, and the cleaning disc 72 is located inside the dust cover 21. The driving shaft of the motor 71 is installed at the bottom of the cleaning disc 72. A cleaning cloth is provided on the cleaning disc 72. The motor 71 can drive the cleaning disc 72 to rotate. When the gasket moves to the bottom of the cleaning disc 72, the cleaning cloth on the cleaning disc 72 can wipe the water on the gasket.

[0064] Working principle: During detection, the gaskets are first placed in multiple clamping rings 47 in sequence and clamped by the clamping rings 47, while the top and bottom ends of the gaskets extend out of gear 2 46, and then motor 2 32 drives the slide plate 41 to rotate around the rotating column 33 through the slider 44 in the rotating column 33, and the slide plate 41 drives the gasket on the clamping ring 47 to move in the dust cover 21 through the gear 2 46 on the mounting seat 45. During the movement of the gasket, the cleaning member 57 in the grinding mechanism 50 and the polishing mechanism 60 grinds and polishes the gasket in sequence, and when the gasket enters the connecting cover 29, the gear 1 43 meshes with the rack 23, and the rotating column 33 continues to rotate at this time. Under the action of the rack 23, the rotating shaft 42 drives the gasket to rotate around the rotating shaft 42 through the slide plate 41, so that the bottom end of the gasket faces upward, and when the gasket moves to the bottom of the cleaning disk 72, the cleaning cloth on the cleaning disk 72 can wipe the water on the gasket to ensure the cleanliness of the detection surface.

[0065] When the gasket moves to the detection groove 27, the gasket is located at the top of the placement plate 15. At this time, the lifting column 14 drives the placement plate 15 to move up. At the same time, the lifting column 14 drives the clamping ring 47 and the gasket to move up through the placement plate 15, so that the gasket is close to the pressure head 12. At the same time, the pressure ring 133 is pressed on the mounting seat 45, and the slider 44 disengages from the slide groove 34 and enters the ring groove 35 to prevent the vibration generated during the grinding, polishing and cleaning of other gaskets from affecting the gasket during detection.

[0066] When the pressure ring 133 is pressed on the mounting seat 45, the mounting seat 45 can be clamped by the pressure ring 133 and the supporting plate 16 to prevent the mounting seat 45 from shifting, thereby preventing the gasket from shifting. At the same time, the limit shaft 135 is inserted into the limit sleeve 49, and then the pressure head 12 moves down and squeezes the gasket. When the gasket is pressed by the pressure head 12 at a certain position, the motor 134 drives the limit sleeve 49 to rotate through the limit shaft 135, and the limit sleeve 49 drives the clamping ring 47 in the gear two 46 to rotate through the gear three 48 to drive the gasket to rotate, thereby changing the position of the gasket, so that the pressure head 12 can detect other positions on the gasket to achieve the effect of multi-point detection of the gasket.

[0067] When one end of the gasket to be tested is tested, the lifting column 14 is reset and drives the gasket to reset. At this time, the rotating column 33 continues to rotate to drive the untested gasket into the testing groove 27. At the same time, the gasket that has been tested enters the dust cover 21 again to grind, polish and clean the untested end of the gasket. When one end of all the gaskets is tested, the other end of all the gaskets is tested, and the test points on both ends of the gasket are made symmetrical to fully reflect the hardness of the gasket and avoid affecting the detection accuracy of the gasket hardness.

[0068] The strength method of the octagonal gasket of the present invention is carried out using the strength detection device of the octagonal gasket, and comprises the following steps:

[0069] S1: The gaskets are sequentially placed into a plurality of clamping rings 47 and clamped by the clamping rings 47, and the top and bottom ends of the gaskets are extended out of the second gear 46, and then the second motor 32 drives the slide plate 41 to rotate through the rotating column 33 and the gaskets move in the dust cover 21;

[0070] S2: During the movement of the gasket, the grinding mechanism 50 and the polishing mechanism 60 grind and polish the gasket in turn. When the gasket enters the connecting cover 29, the gear 1 43 meshes with the rack 23. At this time, the rotating shaft 42 drives the gasket to rotate around the rotating shaft 42 through the slide plate 41, so that the bottom end of the gasket faces upward. When the gasket moves to the bottom of the cleaning plate 72, the cleaning plate 72 wipes the water on the gasket;

[0071] S3: When the gasket moves to the top of the placement plate 15, the lifting column 14 drives the clamping ring 47 and the gasket to move upward through the placement plate 15, so that the gasket is close to the pressure head 12, and at the same time, the pressure ring 133 is pressed on the mounting seat 45, the limiting shaft 135 is inserted into the limiting sleeve 49, and the slider 44 enters the ring groove 35;

[0072] S4: During the detection, the pressure head 12 presses the gasket. When the pressure head 12 presses a point, the motor 134 drives the limit sleeve 49 to rotate through the limit shaft 135. The limit sleeve 49 drives the clamping ring 47 in the gear 2 46 to rotate through the gear 3 48, so as to drive the gasket to rotate, so that the pressure head 12 detects other positions on the gasket.

[0073] S5: After one end of the gasket is inspected, the gasket is put into the dust cover 21 again, and the other end of the gasket is ground, polished and cleaned to inspect the other end of the gasket and make the inspection points on both ends of the gasket symmetrical.

[0074] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
