[0013] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0014] A detection device for sleeve springs of oil seal products comprises an oil injector 1, an oil plug 2, a guide column 3, a metering valve 10 and an oil pump 12; the oil injector 1 is connected to the device by bolts installed in three stepped holes 1-1 arranged in an array on its bottom plate; the oil plug 2 is fixedly installed in the oil injector 1 by screws 6, and the outer wall of the oil injector 1 is provided with a plurality of oil injection holes 1-2 uniformly distributed along its circumference through its thickness direction, and an oil passage 13 is left between the oil plug 2 and the oil injector 1, and each of the oil injection holes 1-2 is connected to the oil passage 13; grease is coated on the surface of the oil seal 5 through the oil injection holes 1-2; the upper surface of the bottom plate of the oil injector 1 Plug in the guide post 3, which is connected to the quantitative valve 10 for signal transmission through the wire 9. The upper end of the guide post 3 is in contact with the spring of the oil seal product, and the upper end surface is designed to be round to prevent burrs from scratching the product; the lower end is fixed to the insulating guide sleeve 4; the wire 9 is used for signal transmission and is installed in the wire groove 1-7 to transmit the signal sensed by the guide post 3 to the quantitative valve 10; the oil inlet end of the quantitative valve 10 is connected to the oil outlet end of the oil pump 12 through the corresponding oil pipe 11, and the oil outlet end of the quantitative valve 10 is connected to the oil passage 13 through the corresponding oil pipe 11, and the quantitative valve 10 is used to quantitatively control the grease transmitted by the oil pump 12.

[0015] An insulating guide sleeve 4 is inserted into the upper surface of the bottom plate of the oiler 1 through interference fit, and a guide column 3 is inserted into the insulating guide sleeve 4. The insulating guide sleeve 4 is a protective unit to prevent the guide column 3 from contacting iron products other than the oil seal spring and affecting the detection result.

[0016] A spring washer 7 is provided between the screw 6 and the oil injector 1 , and the spring washer 7 can prevent the screw 6 from loosening.

[0017] A flat washer 8 is provided between the screw 6 and the oil injector 1 , and the flat washer 8 can increase the pre-tightening force of the screw 6 .

[0018] The upper surface edge of the oil injector 1 is provided with end face fillets 1-4 to remove sharp edges to prevent scratches during installation of the oil seal.

[0019] When using the utility model, the oil seal 5 to be tested is first mounted on the outer side of the oil injector 1, and then the grease to be coated for testing is loaded into the oil pump 12. During the process, the grease should be continuously stirred to discharge the air therein; compressed air is introduced into the oil pump 12, and the piston ring is pressed against the grease in the cavity by the air pressure, and the grease is squeezed into the metering valve 10 through the oil pipe 11 (this is the prior art, so it is not repeated here); if the guide column 3 contacts the spring of the oil seal 5, a signal is transmitted to the metering valve 10, thereby starting the metering valve 10 to coat the grease on the surface of the oil seal 5 through the oil filling hole 1-2; if the oil seal is not covered with a spring, the oil seal is not oiled, thereby selecting the products without a spring. This method is convenient to operate, efficient, and reduces costs.
