Description

Technical Field

[0001] The present invention relates to the technical field of bearing bush detection, and particularly to a high-wear-resistant bearing bush processing detection device and its using method. Background Technique

[0002] A high-wear-resistant bearing bush is a key component used to support a rotating shaft in mechanical equipment. Its core function is to reduce the friction and wear between the shaft and the bearing seat through material properties and structural design, improving the reliability and service life of the equipment. During the production and processing of high-wear-resistant bearing bushes, it is often necessary to perform coating thickness detection. If the coating thickness is insufficient, the wear-resistant layer will be quickly worn, exposing the base material and losing its protective effect; if the coating thickness is too thick, it may affect the fitting accuracy between the bearing bush and the shaft, increasing the frictional resistance.

[0003] The existing detection method is generally as follows: The staff holds a coating thickness gauge and presses the probe against the surface of the high-wear-resistant bearing bush at multiple points. However, since the high-wear-resistant bearing bush is arc-shaped, it is inconvenient to keep the probe perpendicular to the high-wear-resistant bearing bush and in contact with its surface, affecting the detection effect. At the same time, if the measured coating thickness is too thick or too thin, it is inconvenient to quickly make different marks on the surface of the high-wear-resistant bearing bush for recording and differentiation, affecting the detection efficiency and subsequent unqualified analysis of the high-wear-resistant bearing bush.

The toothed ring 15 is fixedly sleeved on the outer wall of the turntable 16. The toothed ring 15 and the gear 14 are meshed with each other.

[0022] The limiting mechanism includes two collars 25 which are rotatably sleeved on the outer wall of the circular tube 26 in sequence from top to bottom. Two splicing rods 24 are symmetrically and fixedly connected to the outer walls of the two collars 25. The lower ends of two of the splicing rods 24 and the lower ends of the other two splicing rods 24 are respectively fixedly connected with a first connecting ring 22 and a second connecting ring 23. The first connecting ring 22 is located outside the second connecting ring 23. The diameter of the first connecting ring 22 is larger than that of the second connecting ring 23.

[0023] The limiting mechanism further includes two V-shaped grooves 29 which are respectively opened at the lower ends of the first connecting ring 22 and the second connecting ring 23. The tops of the two V-shaped grooves 29 are respectively provided with a rotating column 28 in a fitting manner. One ends of the two rotating columns 28 are respectively rotatably connected to the upper edges of the outer walls of the two connecting rods 21.

The upper first magnetic block 30 and the lower first magnetic block 30 are arranged in a staggered manner. The upper second magnetic block 31 and the lower second magnetic block 31 are arranged in a staggered manner.

[0025] The clamping mechanism includes a first electric push rod 8 which is fixedly installed on the horizontal part of an L-shaped support 10 through a mounting seat. The telescopic shaft end of the first electric push rod 8 is fixedly connected to a first motor 7. The output shaft end of the first motor 7 is fixedly connected to a V-shaped frame 6. Two concave clamps 5 are fixedly installed at both ends of the V-shaped frame 6. The inner concave surfaces of the two concave clamps 5 jointly clamp and install a bearing shell body 4.

[0026] Working principle: First, place the bearing shell body 4 inside the inner sides of two concave jigs 5 and fix the bearing shell body 4 through the two concave jigs 5 (it should be noted that the concave jig 5 is mainly composed of a concave block and a screw rod. The screw rod thread penetrates through the concave block. The bearing shell body 4 contacts the inner concave surface of the concave block. Rotate the screw rod so that the screw rod moves towards the bearing shell body 4 until it tightly abuts against it), as Figure 1 shown. Subsequently, start the second electric push rod 11 to drive the connecting plate 9, the round tube 26, the fixed ring 27, the turntable 16, the probe 3, and the two marker pens 17, etc. to move downward together until the lower end of the probe 3 contacts the arc surface of the bearing shell body 4 and the probe 3 is perpendicular to the bearing shell body 4. At this time, observe the display data on the instrument 1 to determine whether the surface coating thickness of the bearing shell body 4 meets the standard. If the displayed coating thickness is too thin, start the second motor 13 at this time to drive the gear 14 to rotate clockwise. The gear 14 will drive the toothed ring 15 and the turntable 16 to rotate counterclockwise together. The turntable 16 will drive the two connecting rods 21, the two marker pens 17, the two rotating columns 28, etc. to rotate counterclockwise together. The two rotating columns 28 will respectively push the V-shaped grooves 29 on the first connecting ring 22 and the second connecting ring 23.

[0027] Among them, when the rotating column 28 below the first connecting ring 22 rotates counterclockwise, since the first connecting ring 22 is connected to the upper sleeve ring 25 through two splicing rods 24, and the first magnetic block 30 connected to the upper end of the upper sleeve ring 25 fits with the second magnetic block 31 located above, the second magnetic block 31 is fixedly connected to the round tube 26 and can be combined Figure 4 with Figure 5As shown in the figure, under the blocking action of the upper magnetic block 2 31, the rotating column 28 cannot push the V-shaped groove 29 to drive the first connecting ring 22 to rotate. Consequently, it cannot drive the two splicing rods 24 and the upper collar 25 to rotate. The rotating column 28 will move downward along its surface due to the extrusion with the V-shaped groove 29, and will drive the connected connecting rod 21 to slide downward within the turntable 16. The connecting rod 21 will drive the connected connecting block 20, connecting column 19, first spring 18 and marker pen 17 to move downward together. The lower end of the marker pen 17 will come into contact with the surface of the bearing body 4 until the rotating column 28 moves downward to the lower end face of the first connecting ring 22. At this time, the connected connecting rod 21, connecting block 20 and connecting column 19 will move further downward, and the first spring 18 between the connecting block 20 and the marker pen 17 will also be compressed, enabling the lower end of the marker pen 17 to maintain close contact with the surface of the bearing body 4. The marker pen 17 rotates counterclockwise, and the surface of the bearing body 4 is an arc surface with different heights. Under the action of the first spring 18, the marker pen 17 can slowly draw a circle adaptively around the probe 3 on the surface of the bearing body 4 until the magnet 1 30 connected to the upper end of the upper collar 25 rotates to the other side of the upper magnetic block 2 31. Subsequently, the second motor 13 is turned off. At this time, an open circle will be drawn on the surface of the bearing body 4 and will rotate around the probe 3.

[0028] Among them, when the rotating column 28 below the second connecting ring 23 rotates counterclockwise, the second connecting ring 23 is connected to the lower collar 25 through two splicing rods 24. The magnet 1 30 connected to the upper end of the lower collar 25 is in contact with the lower magnetic block 2 31. At this time, due to the dislocation arrangement between the upper magnet 1 30 and the lower magnet 1 30, and the dislocation arrangement between the upper magnetic block 2 31 and the lower magnetic block 2 31, and combined with Figure 4 With Figure 5 As shown in the figure, when the magnet 1 30 connected to the upper end of the lower collar 25 rotates counterclockwise, it will not be blocked by the lower magnetic block 2 31. When the rotating column 28 rotates and pushes the V-shaped groove 29 on the second connecting ring 23, it can drive the second connecting ring 23 to rotate synchronously. The second connecting ring 23 can drive the lower collar 25 to rotate counterclockwise outside the circular tube 26 through two splicing rods 24. Then, the connecting rod 21, connecting block 20, connecting column 19, first spring 18 and marker pen 17 connected to the rotating column 28 below the second connecting ring 23 will not move downward but will only rotate counterclockwise together.

[0029] In summary, when the turntable 16 rotates counterclockwise, only one marker pen 17 will draw an open circle on the surface of the bearing bush body 4. Conversely, if the thickness of the display coating is too thick, when the second motor 13 is started to drive the gear 14 to rotate counterclockwise, the turntable 16 will rotate clockwise. For the opposite principle, the lower collar 25, the two splicing rods 24, the second connecting ring 23, and the first magnet 30 will not rotate under the restricting action of the second magnet 31 below. The connecting rod 21 corresponding to the second connecting ring 23 will move downward, and the marker pen 17 connected to the connecting rod 21 will move downward and draw an open circle on the surface of the bearing bush body 4. However, the upper collar 25, the two splicing rods 24, the first connecting ring 22, and the first magnet 30 will not be restricted by the second magnet 31 above and will rotate, driving the corresponding marker pen 17 to rotate together. The two marker pens 17 have different colors, and it is very convenient to use by selecting which marker pen 17 moves downward and draws an open circle through the forward and reverse rotation of the second motor 13, so as to draw circular marks of different colors on the too-thin and too-thick parts of the surface of the bearing bush body 4, which not only improves the detection efficiency but also facilitates the subsequent analysis of the unqualified parts of the bearing bush body 4.

[0030] It should be noted that starting the first electric push rod 8 can control the left and right movement of the first motor 7, the V-shaped frame 6, and the two concave clamps 5. Starting the first motor 7 can drive the V-shaped frame 6 and the two concave clamps 5 to rotate. Then, the bearing bush body 4 can move and rotate in the left and right directions, so as to facilitate the detection of the coating thickness at different parts of the surface of the bearing bush body 4. Moreover, the probe 3 is perpendicular to the bearing bush body 4, which can improve the detection effect.

[0031] The present invention also discloses a usage method for the processing and detection of a highly wear-resistant bearing bush, and the method includes the following steps: S1: First, fix the bearing bush through the clamping mechanism; S2: Second, through the lifting mechanism, the round tube 26, the fixed ring 27, the turntable 16, the probe 3, etc. can be driven to move downward until the lower end of the probe 3 touches the outer surface of the bearing bush. At this time, observing the instrument 1 can determine whether the coating thickness on the surface of the bearing bush meets the standard; S3: Third, through the clamping mechanism, the bearing bush can also be driven to rotate so that the probe 3 can detect the coating thickness in the vertical direction at different positions on the surface of the bearing bush; S4: Through the mutual cooperation of the recording mechanism, the elastic mechanism, the driving mechanism, and the limiting mechanism, circular marks of different colors can be drawn on the surface of the bearing bush according to the degree of non-compliance of the coating thickness on the surface of the bearing bush, so as to facilitate the subsequent focused analysis by the detection personnel.
