A detection sensor is arranged in the feeding groove 421 of the carrying seat 42, and the detection sensor is used to detect whether there is an output shaft 7 in the feeding groove. The detection sensor can monitor in real time whether there is an output shaft in the feeding groove. The signal can be used for linkage control of subsequent pneumatic clamping jaw actions, and the pick-up operation will only be performed when it is detected that there is material, so as to avoid empty grabbing and improve the intelligentization and reliability of equipment operation.

[0027] As shown in the drawings, Figure 1As shown, the press-fitting mechanism 5 includes a support frame 51 arranged on the workbench 1, a press-fitting cylinder 52 arranged on the support frame 51, and a press head 53 connected to the piston rod end of the press-fitting cylinder 52 and driven by the piston rod to vertically press-fit the output shaft 7 on the inner hole of the bearing 6 into the bearing 6. The press-fitting cylinder is used as a power source to provide smooth and controllable linear press-fitting force, avoid excessive impact force to damage the precision bearing or output shaft, and ensure the smoothness and consistency of the press-fitting process. The press-fitting mechanism is composed of a support frame, a press-fitting cylinder, and a press head, which has a simple structure, low manufacturing cost, and fast response speed of pneumatic components, which helps to shorten the entire assembly cycle. The press head is directly connected to the end of the piston rod for vertical press-fitting, which can effectively prevent the output shaft from being deflected when being pressed into the bearing inner hole, ensure the coaxiality of assembly, and improve the product quality. The pneumatic driving assembly 44 includes a support plate 441 arranged on the workbench 1, a horizontal sliding plate 442 slidably arranged on the support plate 441, and a vertical sliding plate 443 slidably arranged on the horizontal sliding plate 442. The support plate 441 is provided with a first cylinder 444 for driving the horizontal sliding plate 442 to slide horizontally and reciprocally, the horizontal sliding plate 442 is provided with a second cylinder 445 for driving the vertical sliding plate 443 to slide vertically and reciprocally, the vertical sliding plate 443 is provided with a support block 445, and the pneumatic clamping jaw 43 is arranged on the support block 445.

The clamping and carrying mechanism 4 and the press-fitting mechanism 5 are arranged in sequence along the rotation direction of the turntable 2 to form a continuous assembly station. Arranging the clamping and carrying mechanism and the press-fitting mechanism in sequence along the rotation direction of the turntable clearly defines the functional division of each station and forms a continuous and interlocking assembly assembly line. This layout allows each process to be performed simultaneously, optimizes the production cycle, and realizes efficient continuous production.

[0028] As Figures 3-5As shown, the carrier 3 comprises a carrier seat 31 and an elastic clamping mechanism 32, the carrier seat 31 is provided with an accommodating groove 300 for accommodating the bearing 6, the elastic clamping mechanism 32 comprises a positioning block 321 fixed on the carrier seat 31, a positioning clamp plate 322 slidably arranged on the carrier seat 31, and an elastic member 323 connected between the positioning clamp plate 322 and the positioning block 321, the elastic member 323 provides a radial elastic pre-tightening force for moving the positioning clamp plate 322 towards the accommodating groove 300, so as to press the bearing 6 in the accommodating groove 300. Through the design of the elastic clamping mechanism (positioning block, positioning clamp plate and elastic member), an adaptive radial elastic pre-tightening force can be generated for bearings within different size tolerance ranges, reliable clamping is achieved, and at the same time, bearing deformation caused by over-positioning or excessive clamping force is avoided. During rotation of the turntable and pressing, the elastic pre-tightening force can continuously press the bearing in the accommodating groove, preventing the bearing from rotating or shifting in the carrier, and ensuring the position stability of the bearing during station conversion and pressing. The carrier seat 31 is provided with a sliding hole 311 communicating with the accommodating groove 300, the positioning clamp plate 322 is slidably arranged in the sliding hole 311, the elastic member 323 is a spring, one end of the spring abuts against a positioning groove in the positioning block 321, and the other end of the spring abuts against a positioning block 3221 at one end of the positioning clamp plate 322. The sliding hole provides accurate sliding guidance for the positioning clamp plate, ensuring the linearity and stability of the sliding track, making the clamping and loosening actions more smooth and reliable. The other end of the positioning clamp plate 322 has an arc-shaped pressing groove 3222 matched with the outer peripheral wall of the bearing 6. The arc-shaped pressing groove at the end of the positioning clamp plate is matched with the shape of the outer peripheral wall of the bearing, forming a surface contact, which can more evenly distribute the clamping force, prevent the bearing surface from being scratched, and at the same time, the clamping is more stable and reliable. The positioning clamp plate 322 has a guide slope 3223 transitionally connected with the arc-shaped pressing groove 3222 on both sides. The setting of the guide slope makes the bearing outer ring be able to easily push the positioning clamp plate away along the slope when the bearing is put into the accommodating groove, realizing automatic centering and guiding, reducing the difficulty and precision requirement of feeding, and improving the feeding efficiency.

[0029] As Figure 1 and 2As shown, the feeding track 411 comprises a track body 4111 connected between the vibration disc 41 and the carrier seat 42, and a cover plate 4112 arranged on the track body 4111, and a feeding guide channel 4110 for sorting and conveying the output shaft 7 is formed between the track body 4111 and the cover plate 4112, and the feeding guide channel 4110 is communicated between the vibration disc 41 and the feeding groove 421 of the carrier seat 42. By the feeding guide channel composed of the track body and the cover plate, the output shaft is conveyed in a specific channel, effectively preventing the parts from falling, rolling or being stuck with each other during conveying, and ensuring the stability and orderliness of conveying. The cover plate is arranged to form a relatively closed environment for the feeding track, which can reduce dust pollution and avoid external interference to cause abnormal posture of the output shaft during conveying.

[0030] The bearing automatic assembly device realizes full-process automation from bearing feeding, output shaft carrying to final pressing through the cooperative work of the turntable, the carrier, the clamping and carrying mechanism and the pressing mechanism. The turntable as a core conveying unit can form a circulating assembly line, significantly reduces manual intervention and greatly improves the assembly efficiency of the bearing of the reduction gear box. Integrating various functional mechanisms (vibration disc, carrying mechanism and pressing mechanism) on a workbench and arranging around the turntable makes the whole device compact in structure and small in floor space.
