[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The utility model provides Figures 1 to 4 The rapid detection sealing ring equipment shown includes a first processing table 1 and a second processing table 2. The second processing table 2 is located on the right side of the top of the first processing table 1 and can move relative to each other. A support seat 3 is arranged on the top of the first processing table 1, and an adjustment component 4 for displacing the support seat 3 is arranged on the bottom of the first processing table 1. A reciprocating cylinder 5 is fixed on the left side of the support seat 3. The piston rod of the reciprocating cylinder 5 passes through the support seat 3 and is fixed with a fixed seat 6. The inner cavity of the fixed seat 6 is fixedly connected with a fixed frame 7. A fixed cylinder 8 is embedded on the side of the fixed frame 7 away from the reciprocating cylinder 5. A movable rod 9 is movably arranged in the inner cavity of the fixed cylinder 8. A metal proximity switch 10 is fixed on the side of the inner cavity of the fixed frame 7 away from the fixed cylinder 8. One end of the movable rod 9 passes through the inner cavity of the fixed frame 7 and fits with the metal proximity switch 10. The other end of the movable rod 9 passes through the fixed frame 7 and extends outward. A workpiece 11 to be measured is placed on the top of the second processing table 2, and a sealing ring 12 is sleeved on the outer side of the workpiece 11 to be measured.
[0022] By arranging a reciprocating cylinder 5 on the first processing table 1, the reciprocating cylinder 5 drives the movable rod 9 to approach the workpiece 11 to be measured through the fixed seat 6 and the fixed frame 7. The telescopic distance of the reciprocating cylinder 5 can be adjusted according to the change of the size of the workpiece 11 to be measured, so as to ensure that the movable rod 9 can contact the workpiece 11 to be measured before the reciprocating cylinder 5 retracts. When the workpiece 11 to be measured is covered with a sealing ring 12, the movable rod 9 squeezes the metal proximity switch 10, and the metal proximity switch 10 converts the squeezing of the movable rod 9 into an electrical signal. By detecting the presence or absence of the electrical signal, it is determined whether the workpiece 11 to be measured is covered with a sealing ring 12. The device has a simple structure and a fast detection speed, does not affect other detections of the workpiece 11 to be measured, and is very convenient.
[0023] The adjusting component 4 includes a chamber 41 opened inside the first processing table 1, and the inner cavity of the chamber 41 is rotatably connected to a screw rod 42 through a bearing, one end of the screw rod 42 passes through the outside of the first processing table 1 and is fixed with a rotating handle 43, and a threaded sleeve 44 is embedded in the interior of the support seat 3. The bottom of the support seat 3 passes through the inner cavity of the chamber 41 and is threadedly connected to the screw rod 42 through the threaded sleeve 44. Through the cooperation of the adjusting component 4, it is convenient to adjust the position of the support seat 3, and it is convenient to make the maximum telescopic distance of the reciprocating cylinder 5 the same as the maximum distance of the movable rod 9 close to the workpiece 11 to be measured according to the different sizes of the workpiece 11 to be measured without replacing the reciprocating cylinder 5.
[0024] Two sets of slide rails 13 are installed on the top of the first processing table 1, and a slider 14 is slidably connected to the outer side of the slide rail 13. The slider 14 is fixed to the bottom of the fixed seat 6. The slider 14 slides on the top of the slide rail 13 to facilitate the limiting of the fixed seat 6, thereby ensuring the smooth movement of the fixed seat 6 and the fixed frame 7, avoiding the deviation of the moving direction of the movable rod 9, causing the change of the moving distance of the movable rod 9, and affecting the detection result.
[0025] A limiting ring 15 located in the inner cavity of the fixed cylinder 8 is fixed to the outer side of the movable rod 9, and a reset spring 16 is sleeved on the outer side of the movable rod 9. One end of the reset spring 16 is fixed to the left side of the limiting ring 15, and the other end of the reset spring 16 is fixed to the left side of the inner cavity of the fixed cylinder 8. Through the arrangement of the limiting ring 15 and the reset spring 16, the squeezed movable rod 9 can be easily reset by the elasticity of the reset spring 16. When the reciprocating cylinder 5 retracts, the movable rod 9 automatically resets to the initial position, which is convenient for the detection of the next group of workpieces 11 to be tested.
[0026] A protective head 17 is fixed to the end of the movable rod 9 away from the metal proximity switch 10. The protective head 17 has the same height as the sealing ring 12. Through the setting of the protective head 17, the sealing ring 12 on the outside of the workpiece 11 to be measured can be protected to prevent the movable rod 9 from squeezing the sealing ring 12, which may cause damage to the sealing ring 12. At the same time, the height setting of the protective head 17 and the sealing ring 12 ensures that the movable rod 9 can drive the protective head 17 to contact the sealing ring 12.
[0027] The maximum telescopic distance of the piston rod of the reciprocating cylinder 5 is the same as the straight-line distance from the protective head 17 to the workpiece 11 to be measured. By limiting the telescopic distance of the reciprocating cylinder 5 and the distance between the protective head 17 and the workpiece 11 to be measured, it is ensured that the protective head 17 can contact the sealing ring 12 or the workpiece 11 to be measured.
[0028] A PLC control cabinet is arranged outside the first processing table 1 and the second processing table 2, and the reciprocating cylinder 5 is electrically connected to the PLC control cabinet. Through the setting of the PLC control cabinet, it is convenient to receive and process the electrical signal detected by the metal proximity switch 10, and at the same time control the operation of the reciprocating cylinder 5, and then start the alarm mode.
[0029] During specific use, the handle 43 is rotated to make the handle 43 drive the screw rod 42 to rotate, and then the screw rod 42 drives the support seat 3 to slide in the inner cavity of the chamber 41 with the cooperation of the thread sleeve 44, and the position of the support seat 3 is adjusted to make the distance between the outer protective head 17 of the movable rod 9 and the workpiece 11 to be measured the same as the maximum telescopic distance of the reciprocating cylinder 5, and then the second processing table 2 carries the workpiece 11 to be measured to the measured position, and the piston rod of the reciprocating cylinder 5 extends outward, driving the fixed seat 6 and the fixed frame 7 to approach the workpiece 11 to be measured, and then the movable rod 9 and the protective head 17 approach the workpiece 11 to be measured. When the sealing ring 12 is sleeved on the outside of the workpiece 11 to be measured, the protective head 17 abuts against the outside of the sealing ring 12, and at the same time, the movable rod 9 is squeezed to the left by the sealing ring 12, and then the movable rod 9 squeezes the metal to approach the opening. At the same time, the metal proximity switch 10 converts the pressure exerted by the movable rod 9 on it into an electrical signal and transmits it to the PLC control cabinet. After detecting the electrical signal, the PLC control cabinet concludes that a sealing ring 12 is sleeved on the outside of the workpiece 11 to be measured, so that the device continues to operate, and the reciprocating cylinder 5 retracts. At the same time, the movable rod 9 is restored to its initial state with the cooperation of the reset spring 16 and the limit ring 15. When there is no sealing ring 12 on the outside of the workpiece 11 to be measured, the protective head 17 can directly contact the workpiece 11 to be measured. At this time, the movable rod 9 cannot squeeze the metal proximity switch 10, and at the same time, the metal proximity switch 10 has no electrical signal transmitted to the PLC control cabinet. At this time, the PLC control cabinet cannot detect the electrical signal and directly stops the operation of the reciprocating cylinder 5, and starts the alarm mode at the same time, which is convenient for prompting that the workpiece is not sleeved with a sealing ring 12.
