In conclusion, whether the wear-resistant sleeve is matched or not can be judged through different alarm states of the alarm lamp 11, so that the wear-resistant sleeve which is matched is ensured to be pressed on the pump shaft.
Example 2: on the basis of embodiment 1, as shown in fig. 2, 3, 4 and 5, the device further comprises two sliding frames 16, the two sliding frames 16 are respectively and slidably connected to the two limiting plates 4, six friction wheels 17 which are in linear symmetrical distribution are fixedly connected to the inner sides of the sliding frames 16, when the wear-resistant sleeves are completely sleeved on the left part of the fixed cylinder 1, the outer walls of the wear-resistant sleeves are tightly contacted with the friction wheels 17 and used for pulling unqualified wear-resistant sleeves rightwards by virtue of friction force, two telescopic assemblies 18 are fixedly connected between the sliding frames 16 and the limiting plates 4, two first wedge blocks 19 are fixedly connected to end faces, close to each other, of the two sliding frames 16 are limited to unidirectionally rotate towards the right, fourteen extrusion pieces 20 which are axially distributed are fixedly connected to the left part of the push rod 301, the left side surfaces of the extrusion pieces 20 are arranged to be spherical surfaces, the right side surfaces of the extrusion pieces 20 are arranged to be flat surfaces, and the extrusion pieces 20 are matched with the adjacent first wedge blocks 19.
When the wear-resistant sleeve is completely sleeved on the left part of the fixed cylinder 1, the outer wall of the wear-resistant sleeve is tightly contacted with the friction wheel 17, in the press fitting process, if the alarm lamp 11 judges that the wear-resistant sleeve is qualified, the adapted wear-resistant sleeve can be press-fitted on the pump shaft of the water pump leftwards, the push rod 301 leftwards moves to drive the extrusion piece 20 to leftwards, and the first wedge block 19 can only rotate leftwards due to the unidirectional rotation of the first wedge block 19, so that the spherical surface of the extrusion piece 20 intermittently rigidly extrudes the first wedge block 19 to outwards move, thereby driving the sliding frame 16 to outwards move, the telescopic assembly 18 contracts, the sliding frame 16 drives the friction wheel 17 to outwards move, so that the outer wall of the wear-resistant sleeve is intermittently separated from the friction wheel 17, and the press fitting of the wear-resistant sleeve is prevented from being influenced.
If judging through warning light 11 that wear-resisting cover is unqualified, then need pull out unqualified wear-resisting cover from the pump shaft, and under the interference condition, pump shaft and wear-resisting cover close-fitting are difficult to pull down through the hand, need with the help of external force, and concrete operation is as follows: when the friction wheel 17 and the wear-resistant sleeve are not completely separated, the telescopic end of the air cylinder 7 is immediately controlled to shorten and reset, so that the push rod 301 drives the extrusion 20 to move rightwards, the first wedge block 19 is intermittently extruded on the plane of the extrusion 20 to rotate rightwards due to the fact that the first wedge block 19 only rotates rightwards unidirectionally, the first wedge block 19 is not extruded on the spherical surface of the extrusion 20 any more, the telescopic assembly 18 resets to drive the sliding frame 16 to move inwards, the friction wheel 17 is driven to move inwards to be tightly attached to the outer wall of the wear-resistant sleeve, then the whole press-fitting machine is pulled rightwards, and the unqualified wear-resistant sleeve is pulled rightwards under the action of friction force between the friction wheel 17 and the wear-resistant sleeve.
In a word, when wear-resisting cover adaptation is qualified, can just normal pressure dress smoothly, when wear-resisting cover is unqualified, can pull out wear-resisting cover through frictional force, manual pull out the cover friction and hinder the hand under the interference condition avoided.
Example 3: on the basis of embodiment 2, as shown in fig. 6 and 7, the device further comprises a guide ring 21, the guide ring 21 is fixedly connected to the left end of the fixed cylinder 1, the outer diameter of the guide ring 21 is equal to the inner diameter of the qualified wear-resistant sleeve, an annular groove 22 is formed in the outer wall of the guide ring 21, lubricating oil uniformly overflows on the inner wall of the wear-resistant sleeve through the annular groove 22, the fixed cylinder 1 is composed of two inner cavities, a guide pipe 23 is fixedly connected in the cavity on the left side of the fixed cylinder 1, the guide pipe 23 is arranged as a double-channel pipeline, each pipeline of the guide pipe 23 is uniformly communicated with the annular groove 22, a through hole 24 is formed in the cavity on the right side of the fixed cylinder 1, the guide pipe 23 is communicated with the through hole 24, a pi-shaped frame 25 is slidably connected to the left part in the cavity on the right side of the fixed cylinder 1, the pi-shaped frame 25 is used for controlling the opening and closing of the through hole 24, the transverse plate thickness of the pi-shaped frame 25 is equal to the aperture of the through hole 24, when the through hole 24 is plugged up by the pi-shaped frame 25, an oil cavity on the right side of the fixed cylinder 1 is formed into a closed oil cavity, an elastic piece is fixedly connected between the pi-shaped frame 25 and the cavity, the top of the pi-shaped frame 25 is fixedly connected with a rectangular plate 26, the push rod 301 on the top, each upper side is uniformly communicated with the annular groove is uniformly with the annular groove 22, each other is uniformly through the through hole 27, the through hole is fixedly connected with a wedge-shaped block 27, a second wedge-shaped block 27 is only is arranged, and a second wedge 28 is only is in a second wedge 28, 28 is in a second wedge 28, and a second wedge 28 is only is in a second wedge 28, and a second wedge 28 is a wedge 28.
In general, before the wear-resistant sleeve is pressed on the pump shaft, in order to make the wear-resistant sleeve press-fit on the pump shaft better and more smoothly, a layer of lubricating oil is smeared on the inner wall of the wear-resistant sleeve in advance, but the lubricating oil can accumulate on the inner bottom wall of the wear-resistant sleeve under the action of gravity, so that the lubricating oil is unevenly distributed, and in order to make the lubricating oil uniformly smeared on the inner wall of the wear-resistant sleeve, the following operation is needed:
at first, the pi-shaped frame 25 blocks the through hole 24, lubricating oil is filled in the oil cavity at the right side of the fixed cylinder 1 in advance, when the wear-resistant sleeve is completely sleeved at the left part of the fixed cylinder 1, the outer wall of the guide ring 21 is attached to the inner wall of the wear-resistant sleeve, and in the process of pressing the wear-resistant sleeve onto the pump shaft leftwards, the wear-resistant sleeve moves leftwards relative to the guide ring 21, and the push rod 301 drives the fixed block 27 and the second wedge block 28 to move leftwards and rightwards when moving leftwards.
In the process of moving the second wedge-shaped block 28 leftwards, as the second wedge-shaped block 28 can only rotate leftwards unidirectionally, the rectangular plate 26 is rigidly extruded by the second wedge-shaped block 28 to move downwards, so that the pi-shaped frame 25 is driven to move downwards, the elastic piece is compressed, the pi-shaped frame 25 does not block the through hole 24 any more, lubricating oil in the oil cavity flows into the guide pipe 23 through the through hole 24, and then flows into the annular groove 22 of the guide ring 21 through the guide pipe 23, and thus, the lubricating oil uniformly overflows the inner wall of the wear-resistant sleeve moving leftwards through the annular groove 22.
In the rightward movement process of the second wedge-shaped block 28, under the action of friction force between the rectangular plate 26 and the second wedge-shaped block 28, the second wedge-shaped block 28 rotates leftwards unidirectionally and does not squeeze the rectangular plate 26 any more, and the elastic piece resets to drive the pi-shaped frame 25 to slide upwards to block the through hole 24 again, so that the overflow of lubricating oil is stopped during return, and the waste of the lubricating oil is avoided.
