Description

Technical Field

[0001] The present invention relates to the technical field of detection of shaft-connected bearings, and particularly to a detection device for shaft-connected bearings of a water pump. 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. Substantially, it is a double-bearing system with a simplified structure. The two supported bearings have no inner race, and the raceways of the rolling elements are directly made on the shaft. The outer raceways of the two supported bearings are made into an integral body, and both sides of the raceway are sealed with seals to form a combined bearing assembly.

[0003] At present, the detection of shaft-connected bearings of water pumps includes noise detection, vibration detection, sealing detection, and coolant temperature detection, etc. Since the pump body is currently assembled in a step-by-step manner, this assembly method is affected by manual operation and the precision of mechanical seals. Therefore, it is difficult to detect the sealing performance between shaft-connected bearings in real time, and 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.

[0004] In view of this, a detection device for shaft-connected bearings of a water pump is designed to solve the above problems. Summary of the Invention

[0042] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0043] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0044] 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.

[0045] Example 1:

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 real pressure detection mechanism 300 is used to selectively increase the pressure of the solution transferred into the liquid seal detection mechanism 200.

[0047] The liquid seal detection mechanism 200 includes a liquid injection component 240 provided on the pump body and two liquid infusion components 250 provided on the liquid injection component 240;

[0048] The liquid injection component 240 includes a pressure increasing chamber 241, two drainage grooves 242 installed on the inner wall of the pressure increasing chamber 241, two end pipes 243 installed on the outer wall of the pressure increasing chamber 241, inner pads 244 installed on the inner wall of the end pipes 243, a plug column 245 movably installed in the inner pads 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 column head 247 movably installed at the other end of the traction frame 246;

[0049] 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;

[0050] The real pressure detection mechanism 300 includes a protective inner tube 310 provided in the liquid injection component 240, a pressure increasing plug 380 installed at the inner end of the protective inner tube 310, two liquid blocking slide plates 390 provided on the pressure increasing plug 380, and a head 370 provided at the inner end of the protective inner tube 310. The inner end of the head 370 is connected to a water pressure detection tube 360. A chuck 320 is installed at the outer end of the protective inner tube 310, a support plate 330 is provided outside the chuck 320, a plug 350 is installed at the outer end of the protective inner tube 310, and a pushing component 340 is provided at the bottom of the support plate 330;

[0051] The pushing component 340 includes a third screw sleeve 341 installed in the support plate 330, a third screw rod 342 movably installed inside the third screw sleeve 341, and a second spring 343 provided outside the third screw rod 342;

[0052] The inner end of the third screw rod 342 is movably installed inside the clamping plate 230.

[0053] Pre - surround the suspended part of the pump body with four thickened straps 170 in advance, then use two sets of locking components 180 to tighten and fix the adjacent four thickened straps 170. Then use a wrench to adjust the two first screw sleeves 140 to rotate counterclockwise. At this time, the two studs 150 will be boosted and apply extrusion pressure to the two anti - slip members 160. After being compressed, the two anti - slip members 160 can be fixed on the outer wall of the suspended pump body;

[0054] Then adjust the two first lead screws 132 to rotate clockwise. At this time, the two strengthened springs 133 that obtain continuous pressure boost will push the two shaft rods 134 to move horizontally along the inside of the beam rail 131. And the liquid - seal detection mechanism 200 that is suspended and horizontally placed can be adapted and pressed against the inner wall of the suspended pump body;

[0055] Then input the selected solution from one infusion part 250 into the inner cavity of the pressure - boosting chamber 241. The other infusion part 250 also provides a constant - pressure channel for the inner cavity of the pressure - boosting chamber 241. When the solution is effectively injected into the inner cavity of the pressure - boosting chamber 241, the flowing or static solution can effectively detect the sealing performance between the shaft - connected bearings in the pump body;

[0056] For the adjusted third lead screw 342, the third screw sleeve 341 will move horizontally along the threaded section of the third lead screw 342. Finally, the support plate 330 will push the chuck 320 and the protective inner tube 310 to move towards the inside of the pressure - boosting chamber 241. The pressure - boosting plug 380 and the two liquid - blocking slide plates 390 installed at the inner end of the protective inner tube 310 can stably move along the outside of the two drainage grooves 242, so as to continuously boost the pressure of the solution standing in the inner cavity of the pressure - boosting chamber 241. The shaft - connected bearings after being tested for corrosion by different solutions can be continuously pressure - boosted and detected.

[0060] The pressing assembly 130 includes a beam rail 131, a first lead screw 132 installed inside one end of the beam rail 131, a reinforcing spring 133 disposed 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;

[0061] Two clamping bars at the other end of the beam rail 131 are provided with two thickened straps 170 symmetrically distributed.

[0062] Preferably, a gasket is installed on the head of the inner end of the first lead screw 132, one end of the reinforcing spring 133 is fixedly installed on the gasket, and the other end of the reinforcing spring 133 is connected to the guide rod in the middle of the shaft rod 134.

[0063] An external locking assembly 180 is provided between two adjacent thickened straps 170, and the locking assembly 180 is used to lock two adjacent thickened straps 170;

[0064] The locking assembly 180 includes a pressure-bearing frame 181 disposed outside the two thickened straps 170, two pressure blocks 183 movably installed inside the pressure-bearing frame 181, a second screw sleeve 182 installed at one end of the pressure-bearing frame 181, a second lead screw 184 disposed inside the second screw sleeve 182, and an extrusion gasket 185 movably installed at the inner end of the second lead screw 184;

[0065] The anti-slip member 160 is composed of a stainless steel shell and a thickened rubber pad, and the bottom of the thickened rubber pad is provided with anti-slip corrugated protrusions.

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, and finally the two pressure blocks 183 will exert a constant pressure outwards, so as to tighten and fix two adjacent thickened straps 170.

[0067] Embodiment 3:

[0068] 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;

[0069] An annular groove is formed on the outer wall of the cover 210, and two sealing rings are provided on the inner end of the cover 210;

[0070] A thickened rubber gasket is provided at the inner end of the pressurization chamber 241.

[0071] Preferably, the threaded section of the cover 210 is installed in the threaded slot at the outer end of the pressure increasing 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;

[0072] After the solution is input from one of the infusion parts 250, the other infusion part 250 can balance the solution input into the inner cavity of the pressure increasing chamber 241. After the solution in the inner cavity of the pressure increasing chamber 241 reaches a constant pressure, a squeezing force can be applied through the pressure increasing 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 pressure increasing plug 380 and the two liquid blocking slide plates 390, so that the corrosion condition of the shaft-connected bearing can be detected in real time.

[0073] Embodiment 4:

[0074] 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;

[0075] Two gaskets are provided on the tube body at the inner end of the end head 370;

[0076] The pressure increasing 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.

[0077] Preferably, during actual use, the end head 370 can be replaced by a pressure detector, and the water pressure detection tube 360 can be replaced by a wire. When the solution is not input along the two infusion parts 250 and the inner end of the end head 370 continuously approaches the outer end of the protective inner tube 310, the end head 370 after empty movement can effectively enhance the stability of the protective inner tube 310.

[0078] 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 at the suspended part of the platform. Then, the pump body is fixed by using an external fixture. Then, the four adjacent thickened straps 170 are wound around the suspended surface of the water pump. Then, the 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 one 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;

[0079] 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 members 160 under the rotation boost until the two anti-slip members 160 are respectively fixed at the top and bottom of the suspended part of the pump body.

[0080] 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 water pump suspension cavity. 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 entire liquid injection assembly 240 will be pressed against the inner wall of the suspended part of the pump body under the traction force.

[0081] 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 liquid blocking slide plates 390 move to the inner wall of the drainage groove 242, the two end tubes 243 are respectively connected to the inner cavity of the pressurization chamber 241 through the two drainage grooves 242. Then, use the liquid infusion member 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 liquid infusion member 250 until the solution to be tested in the inner cavity of the pressurization chamber 241 is balanced, and then the two liquid infusion members 250 can be sealed.

[0082] Next, control the third lead screw 342 to rotate clockwise. At this time, the pressurization plug 380 can drive the two liquid blocking slide plates 390 to apply a gradually changing squeezing force to the inner cavity of the pressurization chamber 241. At this time, the constant amount of the solution to be tested in the inner cavity of the pressurization chamber 241 can detect the sealing performance of the shaft-connected bearing during rotation. According to the different corrosion degrees of different solutions on the shaft-connected bearing after contact, this device can detect the corrosion phenomenon and airtightness of the shaft-connected bearing after gradually increasing the pressure with different solutions.

[0083] 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 purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
