[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-6 As shown, a bearing press-fitting device includes a frame 1 and two slide rails 2 fixed on the frame 1. A material carrier 3 is slidably provided on the slide rails 2. The flange bearing seat 11 is placed on the positioning fixture 4, and the bearing 10 is fitted onto the positioning fixture 4. The bottom end of the positioning fixture 4 supports and positions the flange bearing seat 11, and the upper part positions the bearing 10.
[0021] As a technical optimization of this utility model, a gantry frame 5 is installed on the frame 1, and a pressing assembly 6 is fixed on the gantry frame 5; the material carrier 3 and the slide rail 2 are limited by a limiting assembly 7, and two limiting holes 8 are provided on the slide rail 2 on the left side. A limiting rod 701 is slidably provided on the material carrier 3, and the limiting rod 701 engages with one of the limiting holes 8; a spring 702 is installed at the end of the limiting rod 701, and the spring 702 is located inside the material carrier 3; a push block 703 is fixed on the limiting rod 701, and the side wall of the push block 703 is arc-shaped to facilitate contact between the thumb and the push block 703; Block 703 drives the limiting rod 701 to slide away from the limiting hole 8. The limiting rod 701 is compressed by the spring 702. After the limiting rod 701 slides out from one of the inner limiting holes 8, it pulls the material carrier 3, which facilitates the sliding of the material carrier 3 with the slide rail 2. This makes the material carrier 3 move outward, making it more convenient and safe to place the bearing 10 and the flange bearing seat 11. Since the end of the limiting rod 701 is trapezoidal, after the material carrier 3 is pulled outward, when the limiting rod 701 corresponds to the outer limiting hole 8, the spring 702 extends and drives the limiting rod 701 to slide into the limiting hole 8, thereby preventing the material carrier 3 from continuing to slide and preventing the material carrier 3 from slipping off the slide rail 2.
[0022] As a technical optimization of this utility model, the slide rail 2 is provided with a waist-shaped groove 9, and a bolt passes through the waist-shaped groove 9. The slide rail 2 is fixed to the frame 1 by the bolt, which facilitates the installation of the slide rail 2 on the frame 1.
[0023] As a technical optimization of this utility model, a hydraulic press 604 is installed on the gantry frame 5. A pressure plate 602 is fixed at the bottom end of the hydraulic press 604, and a pressure head 601 is fixed at the bottom end of the pressure plate 602. The hydraulic press 604 extends to drive the pressure plate 602 to move the pressure head 601 downward. The pressure head 601 presses the bearing 10 into the flange bearing seat 11. Two guide rods 603 are fixed on the pressure plate 602. The guide rods 603 are slidably connected to the gantry frame 5. The setting of the guide rods 603 makes the sliding of the pressure plate 402 more stable.
[0024] In use, the pusher 703 is pulled by the thumb while holding the handle. The pusher 703 causes the limiting rod 701 to slide away from the limiting hole 8. The limiting rod 701 is compressed by the spring 702. After the limiting rod 701 slides out of one of the inner limiting holes 8, it pulls the material carrier 3, facilitating the sliding of the material carrier 3 with the slide rail 2. This allows the material carrier 3 to move outward, making it easier and safer to place the bearing 10 and the flange bearing seat 11. Because the end of the limiting rod 701 is trapezoidal, after the material carrier 3 is pulled outward, when the limiting rod 701 corresponds to the outer limiting hole 8, the spring 702 extends and drives the limiting rod 701 to slide into the limiting hole 8, thereby preventing the material carrier 3 from continuing to slide and preventing the material carrier 3 from sliding outward. Slide off from slide rail 2; then place flange bearing seat 11 on positioning fixture 4, and put bearing 10 on positioning fixture 4 so that bearing 10 is at the top of flange bearing seat 11; hold the handle and pull push block 703 with your thumb. Push block 703 drives limit rod 701 to slide away from limit hole 8. Limit rod 701 is compressed by spring 702. After limit rod 701 slides out from one of the inner limit holes 8, it pushes the material carrier 3 so that the material carrier 3 slides to the bottom of the pressure head 601. At this time, positioning fixture 4 and pressure head 601 correspond one-to-one. Hydraulic press 604 extends to drive pressure plate 602 to drive pressure head 601 to move downward. Through pressure head 601, bearing 10 is pressed into flange bearing seat 11.
