Description

Technical Field

[0001] The invention relates to the technical field of air springs, and in particular to a shock-absorbing rubber bladder leakage detection device. Background Art

[0002] During the assembly process of the shock-absorbing rubber bladder of commercial vehicles, it is necessary to go through a leak detection process, that is, after the end of the rubber bladder is buckled with the cover plate, the sealing of the entire bladder, the surface of the cover plate and the bladder itself are tested for leaks.

[0003] The shock-absorbing rubber bladders currently used in commercial vehicles are shown in the attached Figure 1 As shown, the rubber bladder is large in size (φ285x680mm) and heavy in weight (5-10kg / piece). The leak detection process is as follows: first, the operator holds the bladder on the storage table at the edge of the water tank and puts it down, manually rotates the air pipe joint and screws it into the cover plate, then holds the bladder and presses it under the downward pressing tooling in the water, then manually inserts the air pipe and inflates it, and then observes its sealing, air leakage and position. The process lasts for nearly 120 seconds. After the end, the tooling is lifted, and the bladder floats to the surface of the water. The operator takes the bladder out of the water, unplugs the air pipe, loosens the air pipe joint, holds it to the conveyor belt and stands, rotates the bladder with his left hand, and simultaneously uses an air gun in his right hand to blow off the moisture on the surface of the bladder.

[0004] Therefore, the current entire leak detection process takes 150 seconds, with a high degree of manual involvement and low efficiency. Operators need to frequently tighten joints, pull out air pipes, and rotate and blow water, which are heavy and labor-intensive. In addition, their hands are immersed in water for a long time, which makes them prone to swelling in summer and freezing cold in winter. The entire working environment is harsh, which in turn affects the health of the operators' hands. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] like Figure 2-9 As shown, a shock-absorbing rubber bladder leakage detection device proposed in this embodiment includes a box body 1 and a control cabinet 2, and the box body 1 is provided with:

[0041] A positioning station 4, inside which is provided a lifting and lowering fixing tool 41 capable of positioning the bladder 3 and a driving member I for screwing the air pipe connector 46 into the threaded hole in the bladder end cover;

[0042] The leak detection station is provided with a leak detection water tank 5 located below the positioning station 4, and the fixed tooling 41 can drive the bladder 3 to descend into the leak detection water tank 5 for leak detection;

[0043] The drying station 6 is located downstream of the positioning station 4 and is provided with a drying mechanism capable of driving the leather bag 3 to rotate and remove water;

[0044] A material unloading station 8, wherein a placement rack 81 is provided inside;

[0045] The transfer mechanism is arranged between the positioning station 4 and the drying station 6, and can drive the leather bag 3 to move between each station, including a transverse servo module 9 located on the rear side of the fixed tooling 41, and the transverse servo module 9 is equipped with a transport mechanism 10 that can clamp or release the leather bag 3 and perform transverse reciprocating motion.

[0046] In this way, the air pipe joint 46 is automatically tightened by the driving member I, and no manual operation is required, thereby improving efficiency; after the leak detection is completed, the leather bag 3 is moved to the drying station 6 by the transfer mechanism, the moisture of the leather bag is automatically dried by the drying mechanism, and then the leather bag 3 is moved to the placement rack 81 of the unloading station 8 by the transfer mechanism, saving manual rotation and water blowing, and reducing labor intensity; the entire leak detection process is automatically completed except for manual loading and unloading, and the operator does not need to contact water throughout the process, thereby protecting the health of the operator's hands.

[0047] Furthermore, if Figure 3 and Figure 4 As shown, the fixing fixture 41 is set as an annular structure clamped on the outer side of the cover plate at the end of the bladder, and the upper part of the fixing fixture 41 is fixed with a lifting plate 42 through a fixing rod, and the positioning station 4 is also provided with an electric cylinder I 43 and an adsorption mechanism, the output end of the electric cylinder I 43 is fixed to the lifting plate 42, and drives the lifting plate 42 to rise and fall, and the adsorption mechanism includes a cylinder I 44 fixed on the lifting plate 42, and the output end of the cylinder I 44 passes through the lifting plate 42 and is fixed with an electromagnet 45, and the cylinder I 44 drives the electromagnet 45 to descend and adsorb the cover plate at the end of the bladder. Among them, the cover plate in this embodiment is set to metal material.

[0048] Furthermore, the driving part I is set as a servo motor I47, and the servo motor I47 is fixed to the side of the lifting plate 42 through a fixing plate 48. The lower part of the fixing plate 48 is rotatably connected with an air pipe connector 46 through a fixing part. The output end of the servo motor I47 passes through the fixing plate 48 to drive the air pipe connector 46 to rotate so as to be screwed into the threaded hole on the end cover of the bladder.

[0049] The operator first manually lifts the bladder 3 with the cover plate pressed on it and pushes it upward into the fixed tooling 41. Then the control cabinet 2 controls the cylinder Ⅰ44 to start. The cylinder Ⅰ44 pushes the electromagnet 45 to descend and absorb the metal cover plate, and then absorbs the bladder 3. Then the control cabinet 2 controls the servo motor Ⅰ47 to start, drive the air pipe joint 46 to rotate and screw it into the threaded hole on the cover plate; then the control cabinet 2 controls the electric cylinder Ⅰ43 to start, drive the lifting plate 42 to rise and fall, and then drive the fixed tooling 41 and the bladder 3 to descend and immerse in the leak detection water tank 5 below, and start to inflate and pressurize through the air pipe joint 46. During the test, the operator manually observes whether there is a leak and the specific leak location.

[0050] Among them, Figure 3 and Figure 4As shown, columns Ⅰ51 are fixed on both sides of the upper end of the leak detection water tank 5, a horizontal plate Ⅰ52 is fixed between the two columns Ⅰ51, the electric cylinder Ⅰ43 is fixed on the upper end of the horizontal plate Ⅰ52, the output end of the electric cylinder Ⅰ43 passes through the horizontal plate Ⅰ52 and is fixed to the lifting plate 42, and sliding holes Ⅰ are opened on the horizontal plates Ⅰ52 on both sides of the electric cylinder Ⅰ43, and a guide rod Ⅰ53 is slidably connected in the sliding hole Ⅰ, and the lower end of the guide rod Ⅰ53 passes through the sliding hole Ⅰ and is fixed to the lifting plate 42.

[0051] like Figure 8 and Fig. 9 As shown, the transport mechanism 10 includes a clamping jaw assembly 101 electrically connected to the control cabinet 2, an electric cylinder II for driving the clamping jaw assembly to rise and fall, and a cylinder II for driving the clamping jaw assembly to move forward and backward. The clamping jaw assembly 101 includes two parallelly distributed clamping jaws 102 that can approach or move away from each other. Specifically, the transverse servo module 9 includes a servo motor III 91, a transverse screw and a screw barrel. The output end of the servo motor III 91 is fixed to the transverse screw, the screw barrel is threadedly connected to the transverse screw, and the rear side of the transport mechanism 10 is fixed to the screw barrel. Start the servo motor III 91 to drive the transverse screw to rotate, thereby driving the screw barrel to move along the transverse screw, so as to drive the transport mechanism 10 to move along the transverse screw.

[0052] It should be noted that, in order to facilitate the movement of the leather bag 3 between various stations, a conveying mechanism 10 is provided at the rear side of the positioning station 4 and a conveying mechanism 10 is also provided at the rear side of the drying station 6 .

[0053] After the leak detection is completed, the electric cylinder I 43 is started to drive the bladder 3 to rise from the leak detection water tank 5 to about half of the water surface. At this time, the electric cylinder I 43 stops, and then the servo motor I 47 is started to drive the air pipe joint 46 to rotate in the opposite direction again and loosen the threaded hole of the exit cover plate; at this time, the electric cylinder II 103 on the rear side of the positioning station 4 is started to drive the clamping jaw assembly 101 to descend to the stop position of the bladder 3, and the cylinder II 104 is started to push the clamping jaw 102 forward, and the control cabinet 2 controls the two clamping jaws 102 to move synchronously to the middle to clamp the bladder 3 , start the electric cylinder Ⅰ 43 and the electric cylinder Ⅱ 103 at the same time, drive the bladder 3 to rise, and stop after the bladder 3 is completely out of the water. At this time, start the cylinder Ⅰ 44 to drive the electromagnet 45 to rise, and then start the electric cylinder Ⅱ 103 to drive the clamping jaw assembly 101 to descend again, so that the bladder 3 is completely out of the fixed tooling 41, start the cylinder Ⅱ 104 to drive the clamping jaw assembly 101 to retract backwards, so that the bladder 3 retreats and leaves the leak detection station, and then the lateral servo module 9 of the transfer mechanism drives the clamped bladder 3 to translate to the downstream drying station 6.

[0054] Preferably, the box below the drying mechanism is configured as a water collecting box 7, and the water collecting box 7 is used to collect the water thrown out by the skin bag 3 driven by the drying mechanism.

[0055] In this embodiment, Figure 5 , Figure 6and Figure 7 As shown, the drying mechanism includes a drying fixture 61 for positioning the upper end of the leather bag 3 and a servo motor II 62 for driving the drying fixture 61 to rotate. An electric cylinder III 71 is also installed in the water collecting box 7. A leather bag pressing ring 72 is fixed to the output end of the electric cylinder III 71. The electric cylinder III 71 can drive the leather bag pressing ring 72 to move upward and press on the lower end of the leather bag 3. Specifically, columns II 73 are fixed on both sides of the inner wall of the water collecting box 7, and a horizontal plate II 74 is fixed on the upper ends of the two columns II 73. The electric cylinder III 71 is fixed to the lower end of the horizontal plate II 74, and the output end passes through the horizontal plate II 74 and is fixed to the lower end of the leather bag pressing ring 72. At the same time, in order to ensure the stability of lifting, sliding holes II are opened on the horizontal plates II 74 on both sides of the electric cylinder II 103. A guide rod II 75 is slidably connected in the sliding hole II. The upper end of the guide rod II 75 passes through the sliding hole II and is fixed to the lower end of the leather bag pressing ring 72.

[0056] Furthermore, a brush 63 is provided on the drying station 6 , and the brush 63 is located on the side of the leather bag 3 . When the drying mechanism drives the leather bag 3 to rotate and spin off water, the brush 63 is used to assist in drying the water from the leather bag 3 .

[0057] It should be noted that in order to improve work efficiency, the positioning station 4 is provided with at least one fixed tooling 41 and its lifting mechanism, and the drying station 6 is provided with at least one drying mechanism. Specifically, the positioning station 4 and the drying station 6 are provided with two identical toolings, which can simultaneously position and simultaneously dry two leather bags 3. Of course, multiple leather bags can also be tested at the same time, and the number of corresponding fixed toolings, drying mechanisms and conveying mechanisms is consistent with the number of leather bags (for example, three leather bags can be tested at the same time, and correspondingly there are three fixed toolings 41, three drying mechanisms, three leather bag clamping rings 72, three conveying mechanisms 10 on the rear side of the positioning station 4, and three conveying mechanisms 10 on the rear side of the drying station 6, etc.), depending on the specific situation.

[0058] like Figure 5 and Figure 6 As shown, when two drying mechanisms are provided, the servo motor II 62 can simultaneously drive the two leather bags 3 to rotate through a synchronous belt and a synchronous wheel. At the same time, a brush 63 is provided on the side of each leather bag 3.

[0059] Start the cylinder II 104 and extend it forward to push out the clamped leather bag 3, start the electric cylinder II 103, drive the clamping jaw assembly 101 to rise, lift the leather bag 3 upward to the spin-drying tooling 61, and start the electric cylinder III 71 in the water collecting tank 7 to drive the leather bag clamping ring 72 to move upward and hold the leather bag 3; the two parallel clamping jaws 102 of the clamping jaw assembly 101 open and release the leather bag 3, start the cylinder II 104 and retract it backward, the two clamping jaws 102 retract, the control cabinet 2 controls the clamping jaw assembly 101 to move to the right and return to the leak detection station to wait; start the servo motor II 62 to drive the synchronous wheel to rotate, drive the two leather bags 3 to rotate, and throw out the water. At the same time, the brushes 63 on both sides of the leather bag 3 assist in drying the water; after the spin-drying is completed, the cylinder II 104 of the clamping jaw assembly 104 on the rear side of the spin-drying station 6 pushes out the parallel clamping jaws 102 of the leather bag 3. Claw 102 and two clamping jaws 102 clamp the leather bag, and the electric cylinder III 71 in the water collecting tank 7 starts to drive the leather bag clamping ring 72 to descend and detach from the leather bag 3; the electric cylinder II 103 of the clamping jaw assembly 101 on the rear side of the drying station 6 starts to drive the clamping jaw assembly 101, and then drives the leather bag 3 to descend, and the top of the leather bag 3 detaches from the drying tooling 61 and stops. At this time, the cylinder II 104 is started to retract backwards and drive the leather bag 3 to exit the drying station 6; the clamping jaw assembly 101 on the rear side of the drying station 6 moves leftward to the top of the placement rack 81 of the unloading station 8 and stops, and the cylinder II 104 is started to push the clamping jaw assembly 101 to extend forward. At this time, the control cabinet 2 controls the two parallel clamping jaws 102 to release the leather bag 3, and the leather bag 3 falls into the placement rack 81, and the cylinder II 104 retracts backwards, and the clamping jaw assembly 101 moves right and returns to the drying station 6 to wait.

[0060] In summary, the entire leak detection process is completed automatically except for manual loading and unloading. The operator does not need to come into contact with water during the whole process, which protects the health of the operator's hands.
