Description

Technical Field

[0001] The present invention relates to the technical field of shaft-connected bearing detection, and specifically to a detection device for a water pump shaft-connected bearing. Background Technique

[0002] A shaft-connected bearing is a bearing with a special structure and is widely used in fields such as automotive water pumps. It is essentially a double-bearing system with a simplified structure. The two supporting bearings do not have inner raceways, and the raceways of the rolling elements are directly made on the shaft. The outer raceways of the two supporting bearings are made into a whole, and the two sides of the raceway are sealed with seals to form a bearing assembly.

[0003] Currently, the detection of water pump shaft-connected bearings includes noise detection, vibration detection, sealing detection, and coolant temperature detection, etc. Since the current pump body is assembled in a step-by-step manner, this assembly method is affected by manual operation and the mechanical seal accuracy, so it is difficult to detect the sealing performance between shaft-connected bearings in real time. Moreover, the conventional detection methods are single. When the pump body is sealed, it is difficult for conventional detection to simulate the change in the sealing performance of shaft-connected bearings after being corroded by different solution media during actual use.

It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0023] The following describes a water pump shaft-connected bearing detection device provided by some embodiments of the present invention with reference to the accompanying drawings.

The detection and bearing mechanism 100 is used to press the horizontally placed liquid seal detection mechanism 200 against the inner wall of the suspended part of the pump body. The liquid seal detection mechanism 200 is used to provide an effective detection platform for different solutions. The actual pressure detection mechanism 300 is used to selectively increase the pressure of the solution transferred into the liquid seal detection mechanism 200.

[0025] The liquid seal detection mechanism 200 includes a liquid injection assembly 240 provided on the pump body and two liquid infusion members 250 provided on the liquid injection assembly 240; The liquid injection assembly 240 includes a pressurization chamber 241, two drainage grooves 242 installed on the inner wall of the pressurization chamber 241, two end pipes 243 installed on the outer wall of the pressurization chamber 241, an inner gasket 244 installed on the inner wall of the end pipe 243, a plug column 245 movably installed inside the inner gasket 244, a first spring 248 provided on the rod body of the plug column 245, a traction frame 246 movably connected to the inner end of the plug column 245, and a stud head 247 movably installed at the other end of the traction frame 246; The plug column 245 is composed of a cushion plate, a cross bar, and a guide plate, and two sealing rings are provided on the outer wall of the cushion plate; The actual pressure detection mechanism 300 includes a protective inner pipe 310 provided in the liquid injection assembly 240, a pressurization plug 380 installed at the inner end of the protective inner pipe 310, two liquid blocking slide plates 390 provided on the pressurization plug 380, and a head end 370 provided at the inner end of the protective inner pipe 310. The inner end of the head end 370 is connected to a water pressure detection pipe 360. A chuck 320 is installed at the outer end of the protective inner pipe 310, a support plate 330 is provided outside the chuck 320, a plug 350 is installed at the outer end of the protective inner pipe 310, and a push component 340 is provided at the bottom of the support plate 330; The push component 340 includes a third screw sleeve 341 installed in the support plate 330, a third lead screw 342 movably installed inside the third screw sleeve 341, and a second spring 343 provided on the outside of the third lead screw 342; The inner end of the third lead screw 342 is movably installed inside the clamping plate 230.

[0026] First, four thickened straps 170 are wound around the suspended part of the pump body. Then, two sets of locking components 180 are used to tighten and fix the adjacent four thickened straps 170. Then, a wrench is used to adjust the two first screw sleeves 140 to rotate counterclockwise. At this time, the two studs 150 will be boosted to apply a squeezing force to the two anti-slip members 160. After being pressed, the two anti-slip members 160 can be fixed on the suspended outer wall of the pump body; Then, the two first lead screws 132 are adjusted to rotate clockwise. At this time, the two strengthened springs 133 that are continuously pressurized will push the two shaft rods 134 to move horizontally along the inside of the beam rail 131. The suspended and horizontally placed liquid seal detection mechanism 200 can then be adapted and pressed against the suspended inner wall of the pump body; Then, the selected solution is input into the inner cavity of the pressurization chamber 241 from one liquid infusion member 250, and the other liquid infusion member 250 also provides a constant pressure channel for the inner cavity of the pressurization chamber 241. When the solution is effectively injected into the inner cavity of the pressurization chamber 241, the flowing solution or the static solution can effectively detect the sealing performance between the shaft-connected bearings in the pump body; The adjusted third lead screw 342 causes the third nut 341 to move horizontally along the threaded section of the third lead screw 342. Eventually, the support plate 330 will push the chuck 320 and the protective inner tube 310 into the pressurization chamber 241. The pressurization plug 380 and the two liquid-blocking slide plates 390 installed at the inner end of the protective inner tube 310 can move stably along the outside of the two drainage grooves 242, thereby continuously pressurizing the solution that has settled in the inner cavity of the pressurization chamber 241. The shaft-connected bearing after undergoing corrosion tests with different solutions can obtain continuous pressurization detection.

[0027] Embodiment 2: Combined with Figures 1 to 5 As shown, on the basis of Embodiment 1, the detection bearing mechanism 100 includes a clamping member 110 arranged in the circular groove of the cover 210, a lever arm 120 movably installed on the clamping member 110, a pressing component 130 movably installed at the other end of the lever arm 120, a first nut 140 arranged in the pressing component 130, a stud 150 installed in the first nut 140, and an anti-slip member 160 arranged at the inner end of the stud 150.

[0028] Preferably, the two clamping members 110 are installed in the circular groove of the cover 210 through two groups of bolts. One end of the lever arm 120 is movably installed on the end plate outside the clamping member 110. The shaft rod 134 arranged at the other end of the lever arm 120 will move closer to the first nut 140 along the inside of the beam rail 131 under pressure. At this time, the horizontally arranged liquid seal detection mechanism 200 can be tightened in a two-way and constant pressure manner.

[0029] The pressing component 130 includes a beam rail 131, a first lead screw 132 installed at one end inside the beam rail 131, a reinforcing spring 133 arranged at the inner end of the first lead screw 132, and a shaft rod 134 connected to the other end of the reinforcing spring 133; Two clamping rods at the other end of the beam rail 131 are provided with two thickened straps 170 symmetrically distributed.

[0030] Preferably, a gasket is installed on the head at the inner end of the first lead screw 132, and one end of the reinforcing spring 133 is fixedly installed on the gasket. The other end of the reinforcing spring 133 is connected to the guide rod in the middle of the shaft rod 134.

[0031] A locking component 180 is arranged outside two adjacent thickened straps 170, and the locking component 180 is used to lock two adjacent thickened straps 170; The locking component 180 includes a pressure-bearing frame 181 arranged outside the two thickened straps 170, two pressure blocks 183 movably installed inside the pressure-bearing frame 181, a second nut 182 installed at one end of the pressure-bearing frame 181, a second lead screw 184 arranged in the second nut 182, and an extrusion pad 185 movably installed at the inner end of the second lead screw 184; The anti-slip member 160 is composed of a stainless-steel housing and a thickened rubber pad, and anti-slip corrugated protrusions are provided at the bottom of the thickened rubber pad.

[0032] Preferably, the pressure-bearing frame 181 and the two pressing blocks 183 are both made of stainless-steel material, an anti-slip coating is provided on the inner wall of the pressure-bearing frame 181, a rubber layer is provided on the surface of the two pressing blocks 183, and the slider at one end of the pressing block 183 is adaptively penetrated into the slideway on the inner wall of the pressure-bearing frame 181. When the second lead screw 184 rotates, the inner end of the second lead screw 184 will push the extrusion gasket 185 to contract towards the inner cavity of the pressure-bearing frame 181. Finally, the two pressing blocks 183 will apply a constant pressure outwards, so as to tighten and fix two adjacent thickened straps 170.

[0033] Embodiment 3: Combined with Figures 6 to 9 As shown, on the basis of Embodiment 1, the liquid seal detection mechanism 200 further includes a cover 210 installed at the outer end of the pressurization chamber 241, a first sheath 220 installed inside the cover 210, and a clamping plate 230 installed at the bottom of the first sheath 220; An annular groove is provided on the outer wall of the cover 210, and two sealing rings are provided on the inner end of the cover 210; A thickened rubber gasket is provided at the inner end of the pressurization chamber 241.

[0034] Preferably, the threaded section of the cover 210 is installed in the threaded slot at the outer end of the pressurization chamber 241. According to the anti-overflow requirement during the lateral movement of the protective inner tube 310, a sealing gasket needs to be provided on the inner wall of the first sheath 220; When the solution is input from one of the infusion members 250, the other infusion member 250 can balance the solution input into the inner cavity of the pressurization chamber 241. After the solution in the inner cavity of the pressurization chamber 241 reaches a constant pressure, an extrusion force can be applied through the pressurization plug 380 and the two liquid-blocking slide plates 390. Finally, the selected solution in the independent cavity can obtain the gradually changing pressure applied by the pressurization plug 380 and the two liquid-blocking slide plates 390, so as to detect the corrosion condition of the shaft-connected bearing in real time.

[0035] Embodiment 4: Combined with Figure 9 and Figure 10 As shown, in the above embodiment, a T-shaped anti-slip sleeve is installed in the middle of the plug 350; Two gaskets are provided on the tube body at the inner end of the end head 370; The pressurization plug 380 is composed of a disc-shaped plug head and two rectangular baffles, and rectangular transverse grooves adapted to the two drainage grooves 242 are provided on both sides of the disc-shaped plug head.

[0036] Preferably, during actual use, the end 370 can be replaced by a pressure detector, and the water pressure detection tube 360 can be replaced by a wire. When the solution does not flow into the two infusion parts 250, and the inner end of the end 370 continuously approaches the outer end of the protective inner tube 310, the end 370 after displacement can effectively stabilize the protective inner tube 310.

[0037] The working principle and usage process of the present invention: After the shaft-connected bearing is assembled, the exposed end of the water pump needs to be placed on the suspended part of the platform. Then, the pump body is fixed by using an external fixture. Next, four adjacent thickened straps 170 are wound around the suspended surface of the water pump. Then, two adjacent thickened straps 170 are inserted into the inner cavity of the pressure-bearing frame 181 until one thickened strap 170 is located on the top of a second screw sleeve 182, and the other thickened strap 170 is located at the bottom of the other second screw sleeve 182. Then, the four thickened straps 170 are tightened along the suspended part of the pump body. Then, the second lead screw 184 is controlled to rotate clockwise until the pressing pad 185 is pushed by the thrust to press the two pressing blocks 183. At this time, the two pressing blocks 183 can cooperate with the pressure-bearing frame 181 to fix and press the two adjacent thickened straps 170. Next, use a wrench to adjust the two first screw sleeves 140. At this time, the stud 150 will apply a squeezing force to the anti-slip member 160 under the rotation boost until the two anti-slip members 160 are respectively fixed on the top and bottom of the suspended part of the pump body. The inner end of the horizontally placed pressurization chamber 241 in the middle of the two liquid seal detection mechanisms 200 will penetrate through the inner wall of the suspended cavity of the water pump, and the sealing rubber ring at the inner end of the pressurization chamber 241 will fit on the inner wall of the suspended part of the pump body. Then, adjust the two first lead screws 132 to rotate clockwise until the inner end of the first lead screw 132 applies a squeezing force to the reinforcing spring 133. Finally, the continuously pressurized reinforcing spring 133 can push the shaft rod 134 and the top of the force arm 120 to move along the inner chute of the beam rail 131. At this time, the injection assembly 240 as a whole will be pulled to press tightly against the inner wall of the suspended part of the pump body. Next, use a wrench to adjust the third lead screw 342 to rotate counterclockwise. As the third lead screw 342 reverses and extends outward along the inside of the third screw sleeve 341, the support plate 330 will pull the chuck 320 and the protective inner tube 310 to move outward horizontally. The pressurization plug 380 and the two liquid-blocking slide plates 390 installed at the inner end of the protective inner tube 310 will contract along the cavity of the pressurization chamber 241. When the two 290 move to the inner wall of the drainage groove 242, the two end tubes 243 can communicate with the inner cavity of the pressurization chamber 241 through the two pressurization chambers 241. Then, use the infusion part 250 to transfer the solution to be tested into the inner cavity of the pressurization chamber 241. The gas in the inner cavity of the pressurization chamber 241 will be squeezed out from the other infusion part 250 until the solution to be tested in the inner cavity of the pressurization chamber 241 is balanced, and then the two infusion parts 250 can be sealed. Next, control the third lead screw 342 to rotate clockwise. At this time, the pressurizing plug 380 can drive the two liquid-blocking sliding plates 390 to apply a gradually changing extrusion pressure to the inner cavity of the pressurizing chamber 241. At this time, the constant amount of the solution to be measured in the inner cavity of the pressurizing chamber 241 can perform a sealing test on the shaft-connected bearing during rotation. According to the different corrosion degrees of different solutions on the shaft-connected bearing after contact, the device can detect the corrosion phenomenon and airtightness of the shaft-connected bearing after gradually increasing the pressure with different solutions.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
