Description

Technical Field

[0001] The present invention relates to the technical field of torque machines, and in particular to a fully automatic airtightness detection high-speed grease lubrication torque machine. Background Art

[0002] A grease bearing is a special bearing design, usually referring to a bearing pre-filled with grease inside. This design enables the bearing to not require frequent replenishment of grease during use, thereby improving the convenience of maintenance and service life.

[0003] Since the grease bearing is filled with grease inside, performing a sealing test can ensure that the grease does not leak during operation. The loss of grease will cause insufficient lubrication of the bearing, increase friction, and even cause failures and production accidents.

[0004] Grease is the core component of a grease bearing, and its properties directly affect the operating efficiency and life of the bearing. Performing a torque test can help evaluate the performance of the grease under different working conditions: the torque test is convenient for optimizing the grease formula and bearing design, reducing the frictional torque, and improving the operating efficiency; realizing preventive maintenance, detecting potential problems in advance, and extending the bearing life.

[0005] In the prior art, the detection method of grease bearings is complicated and consumes a large amount of manpower; moreover, the airtightness and torque tests need to be carried out separately, and different devices are required for detection, and there are the following technical deficiencies:

[0006] 1. Torque detection needs to be completed using different devices and different processes respectively, and impurities are likely to fall in during the transfer process, causing errors.

[0007] 2. Decentralized detection is difficult to ensure the coherence of detection standards and cannot simulate the performance in actual applications.

[0008] 3. Conventional tests use single-piece feeding. When testing a large number of workpieces, a large amount of human resources are consumed, and the test process is prone to errors due to manual operation. Summary of the Invention

A support rod 10 is fixedly installed between the side surface of each protective plate 2 and the operating table 5. An armrest 3 is fixedly installed at the lower end of the front surface of the protective plate 2. When maintaining the interior of the equipment, the protective plate 2 is pulled up by pulling the armrest 3, and then the support rod 10 connected between the operating table 5 and the protective plate 2 is used for position fixing.

[0033] As Figure 4 shown, the airtightness testing mechanism includes two symmetrically installed rods 104 fixedly installed at the lower end of the fixed cross plate 101. A lifting table 103 is slidably installed at the front end of the installation rod 104.

The sealing ring 105 descends through the hydraulic cylinder 102 to fit the grease bearing, and after pressing, it is judged whether the airtightness meets the standard according to whether gas leaks.

[0034] As Figures 5-6 shown, the material transfer mechanism includes a sliding table 204 fixedly installed at the output end of the telescopic electric cylinder 201. A slide rail 203 is fixedly installed on the upper surface of the reciprocating plate 202. The sliding table 204 is slidably installed at the upper end of the slide rail 203. Two symmetrically installed telescopic motors 205 are fixedly installed on the upper surface of the sliding table 204. The rear end of the telescopic motor 205 is fixedly installed with a linkage cross plate 206.

The telescopic electric cylinder 201 is used to control the reciprocating movement of the sliding table 204 on the reciprocating plate 202, and the two telescopic motors 205 fixedly installed at the upper end of the sliding table 204 are used to move the mounting plate 207, so as to transport the grease bearing to be detected for subsequent testing.

[0035] An installation groove 209 is opened at the upper end of the mounting plate 207. A plurality of fixing plates 210 are slidably installed inside the installation groove 209.

A fixing nut 213 is threadedly engaged with the upper end of the connecting screw 212 on the upper end of the claw 208. The position of the claw 208 at the upper end of the mounting plate 207 is adjusted according to the equipment spacing, and the front and rear positions of the claw 208 are adjusted by controlling the position of the connecting screw 212 in the chute 211.

[0036] As Figures 7-8As shown in the figure, the torque testing mechanism includes a load machine 301 fixedly installed at the rear end of the fixed table 303. The load machine 301 is provided with a torque sensor 302 passing through the fixed table 303. There is an installation vertical seat 308 between the fixed table 303 and the horizontal push motor 306, and a feeding mechanism is provided at the upper end of the installation vertical seat 308. The feeding mechanism limits the bearings to be tested input from the feeding port 11. One side of the torque sensor 302 is attached by the pressing table 304, and torque testing is carried out after the pressing ring 307 is attached.

[0037] The feeding mechanism includes a rotating motor 309 fixedly installed on one side of the installation vertical seat 308. The rotating end of the rotating motor 309 passes through the installation vertical seat 308 and is rotatably installed with a baffle 310. After the test is completed, the rotating motor 309 drives the baffle 310 to open the channel, so that the detected workpiece is transported in cooperation with the material transfer mechanism for subsequent testing.

[0038] The output end of the horizontal push motor 306 is fixedly installed with a pressing table 304, and a pressing ring 307 is fixedly installed inside the pressing table 304.

[0039] Working principle: The grease bearing to be detected is sent into the equipment through the feeding port 11, and the grease bearing to be detected falls along the feeding port 11 onto the guiding plate 7. At this time, the baffle 310 limits the grease bearing.

[0040] The output end of the horizontal push motor 306 fixedly installed on the upper end of the base 305 is fixedly installed with a pressing table 304. There is a pressing ring 307 inside the pressing table 304. The pressing ring 307 is attached to the torque sensor 302 on one side through the horizontal push motor 306, and the load machine 301 conducts torque testing to determine whether the grease bearing meets the standard.

[0041] After the torque test is completed, the rotating motor 309 fixedly installed on the upper end of the installation vertical seat 308 rotates the baffle 310, thereby opening the channel so that the grease bearing to be detected that has completed the torque test continues to be tested along the guiding plate 7.

[0042] When the grease bearing to be detected slides to the upper end of the guiding plate 7 on the right side of the operating table 5, the telescopic cylinder 201 controls the sliding table 204 to move on the upper end of the reciprocating plate 202, and symmetric telescopic motors 205 are provided on the upper surface of the sliding table 204. The two telescopic motors 205 are synchronized in telescoping through the linkage cross plate 206 fixedly installed at the rear end, avoiding misalignment during the movement of the mounting plate 207 due to offset. Through the cooperation of the telescopic cylinder 201 and the telescopic motors 205, the mounting plate 207 performs a reciprocating motion. An installation groove 209 for adjusting the position is provided at the upper end of the mounting plate 207. The positions of a plurality of fixing plates 210 inside the installation groove 209 are adjusted according to the test requirements, and a connecting screw 212 is rotatably fitted to the upper end of each fixing plate 210. The clamping jaw 208 is fixedly installed on the upper surface of the mounting plate 207 through the cooperation of the connecting screw 212 and the fixing nut 213.

[0043] The clamping jaw 208 reciprocates along the upper end of the material guiding plate 7, moving multiple grease bearings equidistantly to the right. The hydraulic cylinder 102 fixedly installed at the upper end of the fixed cross plate 101 operates. The hydraulic cylinder 102 expands and contracts to make the sealing ring 105 at the lower end move up and down along the mounting rod 104. After the sealing ring 105 fits the grease bearing, an airtightness test is carried out to determine whether the lubricating grease meets the use standard.

[0044] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
