[0030] like Figures 1 to 4 The present application illustrates an automatic detection and rapid assembly device for the axial clearance of a double-row tapered roller bearing, which includes: a support frame 1; a transmission portion 2 arranged on the support frame 1; wherein the transmission portion 2 includes: a conveyor belt 21 and guide rails 22 set up on both sides of the conveyor belt 21; a detection portion 3 installed at the input end of the transmission portion 2; and is characterized in that it includes a sample changing portion 4 set up at the output end of the transmission portion 2; a storage portion 5 placed around the sample changing portion 4 and a placement table 6 set between the sample changing portion 4 and the storage portion 5.

[0031] In the prior art, the operation of replacing the middle spacer is performed manually. The operator manually picks up the inner ring assembly, then takes out the original standard middle spacer from the bearing, calculates the clearance, selects a new middle spacer for installation, and then re-installs the original inner ring assembly into the bearing outer ring.

[0032] In one embodiment of the present application, a sample changing section is established at the output end of the transmission section, and a placement table and a storage section that cooperate with the sample changing section are provided. After the double-row tapered roller bearing completes the clearance detection, the storage section delivers the intermediate ring that meets the requirements to the placement table. At the same time, the sample changing section completes the replacement of the intermediate ring of the bearing after the detection is completed, and delivers the assembled bearing to the next link. Finally, the storage section stores the replaced standard intermediate ring in the compartment, which solves the problem of low labor efficiency in the existing technology.

[0033] Please continue to refer to Figure 1 Furthermore, a support frame 1 is constructed as the basic framework of the entire device, upon which the transmission unit 2 is mounted. The core of transmission unit 2 is a horizontally laid conveyor belt 21, flanked by stable guide rails 22 to ensure bearing stability during transport. At the starting end of transmission unit 2, or the input end, is a detection unit 3, which automatically detects the axial clearance of the double-row tapered roller bearing and transmits the detected data to a storage unit 5.

[0034] Please continue to refer to Figure 1Furthermore, after the bearing passes through the detection unit 3 and completes the detection, it continues to move forward along the conveyor belt 21 to the output end, at which time it encounters the sample changing unit 4. The specific structure of the sample changing unit 4 includes a base 41 fixed on the guide rail 22, and a plurality of support rods 42 are vertically mounted on the base. The top of the support rod 42 is connected to a reversing guide rod 43, which can be flexibly moved in the horizontal direction. A first clamping jaw 44 and a second clamping jaw 45 are respectively installed at both ends of the reversing guide rod 43, and a telescopic device is provided between the two, which can accurately control the opening and closing and movement of the clamping jaws as needed, thereby realizing the rapid clamping and release of the bearing and the replacement of the middle spacer ring.

[0035] Please continue to refer to Figure 1 and Figure 3 Furthermore, a storage section 5 is located immediately adjacent to the sample exchange section 4, for storing intermediate rings of varying sizes and conditions. This section consists of shelves 51, which are divided into multiple compartments 52 in a matrix layout. Each compartment is equipped with a height-adjustable support plate 53. To further improve storage efficiency, evenly spaced partitions 55 are placed on the support plates 53, subdividing the compartments into multiple smaller compartments for easier storage of the intermediate rings.

[0036] Please continue to refer to Figure 2 Furthermore, when the sample changing unit 4 releases the tested bearings to the placement table 6, the conveying device 54 located directly above the storage unit 5 is immediately started. The conveying device 54 includes a horizontal guide rail 541 and a longitudinal guide rail 542 perpendicular thereto, which together constitute a two-dimensional mobile platform. The mounting platform 543 slides along the guide rail, on which a support column 544 is provided, and a first telescopic device 545 is installed on the side of the support column, the end of which is connected to a second telescopic device 546 to form a two-stage telescopic structure to increase the operating range. A third clamp 547 is installed at the end of the second telescopic device 546. The clamp has a unique design and consists of two cubic clamps 5471 arranged in the vertical direction and cylindrical clamps 5472 on their respective sides. It can flexibly adapt to middle spacers of different sizes and shapes to achieve precise grasping and transportation.
