Description

TECHNICAL FIELD

[0001] The application relates to the technical field of detection devices, in particular to a device for testing acid and alkali resistance of a ceramic layer on a metal surface. BACKGROUND

[0002] The ceramic film on the surface of a metal part is an important means for increasing the corrosion resistance of the metal, and the wear resistance of the ceramic film is extremely important on key parts. After the ceramic film is made on the surface of the metal part, the integrity of the ceramic film needs to be detected. The ceramic film surface integrity can be detected in a scanning mode, and the ceramic film surface integrity can also be detected by using acid washing liquid and alkali washing liquid. Therefore, the corrosion resistance test of the ceramic film on the surface of the metal part is particularly important. However, the corrosion resistance in the prior art generally includes acid solution corrosion resistance test and alkali solution corrosion resistance test. In the detection process, the detection equipment in the prior art uses an acid-alkali tank, and a series of processes such as hoisting and cleaning are required. The acid corrosion resistance test and the alkali corrosion resistance test cannot be quickly switched, the detection period is too long, the transfer cost is high, the corrosion time of the acid and alkali cannot be accurately grasped, and the detection efficiency and accuracy are low. SUMMARY

[0006] Preferably, the transmission mechanism comprises a transmission rod, a fixed plate, a connecting rod, a storage hopper, the inside of the storage pool is movably provided with a transmission rod at the upper end of the first partition through a bearing, the upper end of the transmission rod is fixedly provided with a fixed plate, one side of the upper end of the fixed plate is movably provided with a connecting rod through a rotating shaft, the upper end of the connecting rod is fixedly provided with a storage hopper, and the metal parts can be slid into the clean water pool, acid detection pool or alkali detection pool for cleaning or detection work through the overturning and tilting of the transmission mechanism.

[0007] Preferably, the upper end of the fixed plate is fixedly provided with an extension rod away from one side of the connecting rod, and the inside of the extension rod is provided with a return spring, so that the storage hopper can be pushed around the rotating shaft of the connecting rod to rotate counterclockwise through the extension rod and the internal spring. Figure 5 The metal parts can enter different positions for detection work; note that the movable end of the extension rod only contacts the storage hopper without being connected.

[0008] Preferably, one side of the upper end of the storage hopper is provided with a notch, and a plurality of through grooves are uniformly formed on the outer surface of the storage hopper, so that the notch can prevent interference between the storage hopper and the second partition during rotation of the storage hopper and the rotating rod, facilitating the rotation and tilting of the storage hopper; and the through grooves can effectively prevent water accumulation in the storage hopper.

[0009] Preferably, the transmission mechanism comprises a worm gear, a worm, and a motor, one end of the transmission rod is fixedly provided with a worm gear, the outer surface of the storage pool is movably provided with a worm below the worm gear through a bearing, the worm and the worm gear are meshed with each other, the surface of the storage pool is fixedly provided with a motor on one side of the worm through a mounting seat, and the output shaft end of the motor is in transmission connection with the worm through a shaft coupling, so that the storage hopper can be overturned around the transmission rod through the transmission mechanism.

[0010] Preferably, the unwinding spiral angle of the worm is less than the friction angle of the contact between the worm gear and the worm, so that when the worm drives the worm gear to rotate, a self-locking function can be achieved, that is, only the worm can drive the worm gear to rotate, and the worm gear cannot self-rotate; thereby preventing the storage hopper from self-rotating without reason.

[0012] Compared with the prior art, the beneficial effects of the present application are:

[0013] The present application adopts an integrated acid-alkali detection structure, which drives the worm to rotate by the motor, so that the metal pieces previously sliding towards the acid detection tank can enter the acid detection tank for immersion detection, and after acid detection is completed, the motor is controlled to drive the worm to rotate, so that the storage hopper tilts towards the clean water tank, so that the metal pieces after acid detection can also fall into the clean water tank, at this time, the motor can drive the entire storage hopper to repeatedly rock and rotate slightly, thereby cleaning the metal pieces, after cleaning is completed, the electric push rod is controlled to retract, so that the counterweight is close to the storage hopper and the connecting rod shaft, at this time, the counterweight gives the storage hopper a rotating force, which is smaller than the elastic force of the telescopic rod and the spring, so that the telescopic rod can be elongated under the action of the spring, thereby pushing the storage hopper to tilt in another direction, so that the storage hopper tilts towards the alkali detection tank, and then the motor drives the storage hopper to continue to rotate towards the alkali detection tank, so that the metal pieces can also enter the alkali detection tank, so that the present application can switch the acid corrosion resistance and alkali corrosion resistance detection, thereby avoiding the participation of manual and other hoisting equipment, which can improve the detection efficiency and ensure the environmental safety.

[0014] The present application drives the entire storage hopper to repeatedly rock and rotate slightly by the motor, thereby cleaning the ceramic film on the surface of the metal pieces, so that the acid and alkali solutions on the surface of the metal pieces can return to the clean water tank each time, thereby preventing the acid and alkali solutions from reacting with each other.

[0015] The present application has the advantages of convenient overall operation, simple structure, and only needs to use the multi-directional tilting of the storage hopper to automatically drive the metal pieces to move in the three functional tanks, which is convenient to use and promote.

[0026] The transmission mechanism comprises a transmission rod 7, a fixed plate 8, a connecting rod 9, and a storage hopper 10. The transmission rod 7 is movably arranged on the upper end of the first partition 2 in the storage tank 1 through a bearing. The fixed plate 8 is fixedly arranged on the upper end of the transmission rod 7. The connecting rod 9 is movably arranged on one side of the upper end of the fixed plate 8 through a rotating shaft. The storage hopper 10 is fixedly arranged on the upper end of the connecting rod 9. The metal parts can be slid into the clean water tank 4, the acid detection tank 5, or the alkali detection tank 6 for cleaning or detection through the overturning and tilting of the transmission mechanism. The telescopic rod 11 is fixedly arranged on the side, away from the connecting rod 9, of the upper end of the fixed plate 8. The telescopic rod 11 is internally provided with a reset spring. The storage hopper 10 can be pushed around the rotating shaft of the connecting rod 9 by the telescopic rod 11 and the internal spring to realize the overturning and tilting of the transmission mechanism. Figure 5The cylindrical metal piece can be moved to different positions for detection work; the movable end of the telescopic rod 11 only contacts the storage hopper 10 without being connected; the upper end of the storage hopper 10 is provided with a notch 12, and a plurality of through grooves 18 are uniformly arranged on the outer surface of the storage hopper 10; the notch 12 can prevent the storage hopper 10 and the rotating rod from interfering with the second partition plate 3 during rotation, thereby facilitating the rotation and tilting of the storage hopper 10; the through grooves 18 can effectively prevent water accumulation in the storage hopper 10; the transmission mechanism includes a worm wheel 13, a worm gear 14, and a motor 15; one end of the transmission rod 7 is fixedly provided with the worm wheel 13; the worm gear 14 is movably arranged on the lower end of the worm wheel 13 on the outer surface of the storage pool 1 through a bearing; the worm gear 14 and the worm wheel 13 are in meshing relationship; the motor 15 is fixedly arranged on one side of the worm gear 14 on the surface of the storage pool 1 through a mounting seat; the output shaft end of the motor 15 is in transmission connection with the worm gear 14 through a shaft coupling; the transmission mechanism can drive the storage hopper 10 to overturn around the transmission rod 7; the unwinding spiral angle of the worm gear 14 is smaller than the friction angle of the contact between the worm wheel 13 and the worm gear 14; thus, when the worm gear 14 drives the worm wheel 13 to rotate, a self-locking function is achieved, that is, only the worm gear 14 can drive the worm wheel 13 to rotate, and the worm wheel 13 cannot rotate by itself; thereby preventing the storage hopper 10 from rotating by itself; Figure 5 The movable end of the electric push rod 16 is fixedly provided with a counterweight 17; when the electric push rod 16 is extended, the counterweight 17 is away from the device where the connecting rod 9 is located; at this time, according to the lever principle, the counterweight 17 gives the storage hopper 10 a rotating force that is greater than the elastic force of the telescopic rod 11 and the spring, so that the storage hopper 10 tilts, as shown in

[0027] Working principle: when using the device, the metal pieces to be detected are placed in the storage hopper 10; then the electric push rod 16 is extended, and the counterweight 17 is away from the device where the connecting rod 9 is located; at this time, according to the lever principle, the counterweight 17 gives the storage hopper 10 a rotating force that is greater than the elastic force of the telescopic rod 11 and the spring, so that the storage hopper 10 tilts, as shown in Figure 5 At this time, the entire storage hopper 10 tilts towards the acid detection tank 5, so that the metal pieces slide towards the acid detection tank 5; then the motor 15 drives the worm gear 14 to rotate, formingFigure 2 When the acid detection is completed, the motor 15 drives the worm 14 to rotate, so that the storage hopper 10 tilts towards the clean water tank 4, and the metal piece that has been subjected to acid detection can fall into the clean water tank 4. At this time, the motor 15 drives the entire storage hopper 10 to repeatedly and slightly vibrate, so that the metal piece can be cleaned. After cleaning, the electric push rod 16 is controlled to retract, so that the counterweight 17 is close to the pivot shaft on which the storage hopper 10 and the connecting rod 9 are located. At this time, the counterweight 17 gives the storage hopper 10 a rotating force that is smaller than the elastic force of the extension rod 11 and the spring. Thus, the extension rod 11 can be extended under the action of the spring, so as to push the storage hopper 10 to tilt in another direction, that is, to tilt towards the alkali detection tank 6. Then, the motor 15 drives the storage hopper 10 to continue to rotate towards the alkali detection tank 6, so that the metal piece can enter the alkali detection tank 6. Thus, the device can quickly switch the detection of acid corrosion resistance and alkali corrosion resistance, thereby improving the detection efficiency. When switching, the metal piece can return to the clean water tank 4, so as to prevent the acid and alkali solutions from reacting with each other. The device is easy to operate and simple in structure, and only needs to use the multi-directional tilting of the storage hopper 10 to automatically drive the metal piece to move in the three functional tanks. Therefore, the device is convenient to use and is easy to popularize. This is the working principle of the metal piece surface ceramic layer acid and alkali resistance testing device.
