Description

Technical Field

[0002] The bearing clearance is the amount of movement when the inner ring or outer ring of the bearing is fixed when it is not installed on the shaft or bearing box, and the unfixed side is moved radially and axially. According to the direction of movement, it can be divided into radial clearance and axial clearance. Bearing clearance detection is an important indicator to measure the quality of bearings, which affects the vibration, noise and service life of bearings. There are mainly the following methods to detect bearing clearance: special instrument detection method, feeler gauge measurement method, micrometer inspection method, simple measurement method, angular clearance detection method.

[0040] First, the bearing to be tested is intermittently transported to the feed port 74 by an external intermittent feeding device, and then the pneumatic push rod 72 is controlled to drive the bearing to move upward through the push plate 73, until the two arc-shaped clamping plates 414 corresponding to the front side clamp the bearing together under the action of multiple compression springs and the telescopic rod 413, and then the incomplete gear 53 and the transmission gear 51 are controlled by the No. 1 motor 52 to drive the support plate 2 to rotate intermittently 120 degrees, and at the same time, the pneumatic push rod 72 is controlled to drive the push plate 73 to move downward and return to its original position.

[0046] See also Figure 2 , Figure 3 , Fig. 9 and Fig.10, the steering and conveying mechanism 10 includes a support vertical plate 101 installed at the upper end of the support disk 1 corresponding to the left circular through hole 3. A sliding L-shaped slide bar 102 is installed on the left side of the front end of the support vertical plate 101. A vertical rod 103 is installed on the right side of the front end of the support vertical plate 101. The right end of the horizontal section of the L-shaped slide bar 102 is a wedge-shaped structure. A circular seat 104 is jointly installed at the upper ends of the support vertical plate 101 and the vertical rod 103. A hemispherical avoidance opening 105 is provided at the upper end of the circular seat 104. And a first blanking slide hole 106 is provided at the lower end of the circular seat 104 corresponding to the positions of the L-shaped slide bar 102 and the vertical rod 103. The first blanking slide hole 106 communicates with the hemispherical avoidance opening 105. A C-shaped baffle 107 is installed at the lower end of the support disk 1. The C-shaped baffle 107 is composed of two vertical plates and a bottom plate. One end of the C-shaped baffle 107 close to the first blanking slide hole 106 is fixedly connected to the corresponding support leg 18.

The output shaft of the forward and reverse motor 109 rotates through the C-shaped baffle 107 and is fixedly connected to a lead screw 110. The lead screw 110 is threadedly connected to the L-shaped slide bar 102.

[0047] After the complete axial clearance detection work of the corresponding bearing, the first motor 52 is used to control the transmission between the incomplete gear 53 and the transmission gear 51 again, driving the support disk 2 to intermittently rotate 120 degrees. At this time, the bearing is located above the circular seat 104. The corresponding incomplete gear 61 and the passive gear 415 are respectively controlled by the two second motors 62 to drive, and the corresponding arc-shaped clamping plates 414 are respectively driven to rotate 180 degrees through the corresponding telescopic rods 413 until the corresponding two arc-shaped clamping plates 414 jointly drive the bearing to rotate 180 degrees. Then, the bidirectional pneumatic push rod 19 is controlled to drive the corresponding limiting rods 417 to move away from each other through the left and right telescopic ends respectively. The corresponding two limiting rods 417 will respectively drive the corresponding arc-shaped clamping plates 414 to move away from each other through the corresponding telescopic rods 413 until the corresponding two arc-shaped clamping plates 414 are both separated from the bearing. At this time, the bearing will slide from the first blanking slide hole 106 onto the L-shaped slide bar 102. It should be noted that the bearing sliding onto the L-shaped slide bar 102 is assisted and limited by the vertical rod 103 to prevent it from rolling off the L-shaped slide bar 102. Then, the bidirectional pneumatic push rod 19 is controlled to drive the corresponding limiting rods 417 to move close to each other and return to the original position through the left and right telescopic ends respectively. Under the action of a plurality of compression springs, the corresponding two limiting rods 417 will respectively drive the corresponding arc-shaped clamping plates 414 to move close to each other and return to the original position.

[0048] Then, control the pneumatic push rod III 22 to drive the radial clearance detector 23 to move towards the bearing on the L-shaped slide rod 102. After the radial clearance detection of the corresponding bearing is completed, control the pneumatic push rod III 22 to drive the radial clearance detector 23 to return to its original position. The clamping mechanism 4, the intermittent rotation mechanism 5, the clamping and flipping mechanism 6 and the steering and conveying mechanism 10 cooperate to drive the bearing after axial clearance detection to rotate intermittently above the circular seat 104 and drive the bearing to flip, so as to achieve the effect of radial clearance detection of the bearing and effectively improve the detection efficiency.

[0049] Refer to Figure 1-Figure 3 and Fig.10 The discharging mechanism 9 includes two discharging ports 91 opened in the middle of one vertical plate of the C-shaped baffle I 107. The C-shaped baffle II 92 is respectively installed corresponding to the two discharging ports 91 on the C-shaped baffle I 107. The electric push rods 93 are respectively installed on the other vertical plate of the C-shaped baffle I 107 corresponding to the two discharging ports 91 through the mounting seats, and the circular push plates 94 are respectively slidably penetrated and installed on the other vertical plate of the C-shaped baffle I 107 corresponding to the two discharging ports 91. The telescopic ends of the electric push rods 93 are fixedly connected to the corresponding circular push plates 94.

[0050] After the radial clearance detection of the corresponding bearing is completed, drive the lead screw 110 to rotate through the forward and reverse motor 109. The lead screw 110 drives the bearing to move downward through the L-shaped slide rod 102 until the L-shaped slide rod 102 fits on the bottom plate of the C-shaped baffle I 107. Since the right end of the horizontal section of the L-shaped slide rod 102 is a wedge-shaped structure, the bearing will lose the auxiliary limit of the vertical rod 103 at this time and roll towards the discharging port 91. It should be noted that a conveying device is arranged outside the bottom plate of the C-shaped baffle I 107. At this time, the external conveying device will drive the bearing after detection to move towards the discharging port 91. During this period, for the bearings with unqualified axial clearance and radial clearance detection, the two electric push rods 93 will respectively push them out through the circular push plates 94 from the corresponding discharging ports 91 and temporarily store them on the corresponding C-shaped baffle II 92 for unified treatment. The bearings that are qualified in both axial clearance and radial clearance detection will be discharged from the discharging port 91.

[0051] It should be noted that when the support plate 2 rotates 120 degrees intermittently each time, the next bearing to be tested is intermittently transported to the feed port 74 by the external intermittent feeding equipment, and then the pneumatic push rod 1 72 is controlled to drive the corresponding bearing to move upward through the push plate 73 until, under the action of multiple compression springs and the telescopic rod 413, the two arc-shaped clamping plates 414 corresponding to the front side will jointly clamp the corresponding bearing, and then the pneumatic push rod 1 72 is controlled to drive the push plate 73 to move downward and return to its original position, thereby achieving the effect of continuous loading. By repeating the above operation, the loading and unloading of the bearing and the axial clearance and radial clearance detection work can be repeated.
