[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figure 1 — Figure 8As shown, a double-bearing press-fitting device includes a fixed plate 101. An upper mounting bracket 102 is bolted to the top of the fixed plate 101, and a lower mounting bracket 103 is bolted to the bottom of the fixed plate 101. A first through hole 104 is formed in the middle of the fixed plate 101. A moving mechanism is provided on the fixed plate 101, including a moving seat 204 movably mounted on the fixed plate 101. A workpiece 206 to be press-fitted is fixedly mounted on the moving seat 204. A pressing mechanism is provided on the fixed plate 101, and a support mechanism is installed on the fixed plate 101. The mechanism includes a support block 403, which is movably mounted on the fixed plate 101. The workpiece 206 to be pressed is a thin plate workpiece, including upper and lower bearing mounting positions. A groove is opened between the two bearing mounting positions. The support block 403 is used to support the workpiece 206 between the upper and lower bearing mounting positions during pressing. The support block 403 is inserted into the groove between the bearing mounting positions and plays a supporting role during bearing pressing to prevent the workpiece from deforming or cracking due to bearing pressing. A second pressing mechanism is provided on the upper mounting frame 102, and a first pressing mechanism is provided on the lower mounting frame 103.

[0030] In this embodiment, the first pressing mechanism includes a first guide sleeve 501, which is bolted to the lower mounting frame 103.

When the output end of the second hydraulic cylinder 609 extends, the guide rail 603 descends, and the guide rail 603 moves the switching seat 605 toward the workpiece.

[0032] In this embodiment, a pressing head 606 and a pressure receiving head 608 are bolted to the switching seat 605. When pressing the bearing, the operator places the second pressing bearing 607 at the bottom of the pressing head 606. The pressing head 606 and the pressure receiving head 608 are arranged side by side and connected by bolts. When pressing the first pressing bearing 504, the pressure receiving head 608 and the first pressing bearing 504 are on the same vertical line, and the pressure receiving head 608 is positioned at the bearing pressing position on the top of the workpiece 206 before the first pressing bearing 504 is pressed. The first pressing bearing 504 bears a certain pressure during pressing to prevent deformation of the workpiece 206 and improve the success rate of pressing.

[0033] In this embodiment, the moving mechanism includes a mounting plate 201, a first slide rail 202 is bolted to the mounting plate 201, a feeding cylinder 203 is bolted to the mounting plate 201, a moving seat 204 is slidably connected to the first slide rail 202, the output end of the feeding cylinder 203 is bolted to the moving seat 204, a second through hole 207 is provided on the moving seat 204, and a hole is also provided on the mounting plate 201, the hole position is the same as the first through hole 104, the bearing pressing position of the second through hole 207 is on the same vertical line as the second through hole 207, in the initial state, the moving seat 204 is located away from the first through hole 104, which facilitates the limiting of the workpiece 206 to be pressed on the moving seat 204.

[0034] In this embodiment, a number of limiting blocks 205 are bolted to the movable seat 204. The limiting blocks 205 are used to limit the workpiece 206 to be pressed.

[0035] In this embodiment, the support mechanism includes a push cylinder 401, which is bolted to the top of the mounting plate 201. The output end of the push cylinder 401 is bolted to a connecting block 402, and the support block 403 is bolted to the connecting block 402.

[0036] In this embodiment, the pressing mechanism includes a fixed frame 301, which is bolted to the fixed plate 101. A pressing cylinder 302 is bolted to the fixed frame 301, and a pressing head 303 is bolted to the output end of the pressing cylinder 302. The pressing head 303 is used to press on the workpiece 206 to be pressed, and to fix the workpiece 206 to be pressed.

[0037] Working principle: In the initial state of use, the movable seat 204 is located away from the first through hole 104. The operator places the workpiece 206 to be pressed between several limit blocks 205 to prevent the workpiece 206 from moving back, forth, left, or right. Then, the first pressing bearing 504 and the second pressing bearing 607 are respectively installed on the top of the pressing seat 503 and the bottom of the pressing head 606. When pressing begins, the output end of the feeding cylinder 203 retracts, and the movable seat 204 moves towards the support block 403 until the support block 403 enters the upper and lower bearing mounting positions of the workpiece 206 to be pressed. Within the groove, the upper and lower mounting positions of the workpiece 206 to be pressed and the second through hole 207 are aligned with the first through hole 104 on the same vertical line. When pressing begins, the switching seat 605 is moved by the switching cylinder 604, positioning the pressure head 608 directly above the bearing mounting position of the workpiece 206. Then, the output shaft of the second hydraulic cylinder 609 extends, pressing down the guide rail 603. The guide rail 603 pushes the switching seat 605 and the pressure head 608 downwards. The pressure head 608 first engages with the bearing pressing position at the top of the workpiece 206, and then the first hydraulic cylinder is activated. 505, the output end of the first hydraulic cylinder 505 extends, pushing the pressing seat 503 upward. The pressing seat 503 lifts the first pressing bearing 504 and moves it towards the bearing mounting position at the bottom of the workpiece 206 to perform the pressing action of the first pressing bearing 504. During pressing, the support block 403 and the pressure head 608 exert pressure, effectively preventing the workpiece 206 from being damaged due to excessive force. After the first pressing bearing 504 is pressed into place, the output end of the second hydraulic cylinder 609 retracts by one distance, and the switching cylinder 604 drives the switching seat 605 to move, so that the pressing head 608... 06 moves directly above the second through hole 207, and then the output end of the second hydraulic cylinder 609 extends again. The second press bearing 607 on the press head 606 presses into the bearing mounting position at the top of the workpiece 206 to be press-fitted. During this press-fitting, the support block 403, the press seat 503 below the workpiece 206 to be press-fitted, and the first press bearing 504 provide support. This completes the press-fitting operation of the double bearing. The clamping cylinder 302, the first hydraulic cylinder 505, and the second hydraulic cylinder 609 retract, and the moving seat 204 is moved away, so that the press-fitted workpiece 206 can be removed.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
