Description

Technical Field

[0001] This utility model belongs to the field of bearing press-fitting technology, specifically relating to a press machine for bearing press-fitting that is easy to adjust. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. When in use, bearings need to be pressed onto the surface of shaft parts using a press.

[0003] Existing presses are inconvenient to adjust with their bottom casters, making movement and positioning difficult and hindering press position adjustments. This issue is a problem that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable bearing press to address the problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a press for easy-to-adjust bearing pressing, comprising a press frame, a support frame fixedly connected to the top of the press frame, a pneumatic clamp provided inside the top of the press frame near the support frame, a hydraulic cylinder mounted on the top of the support frame, a pressing plate fixedly connected to the bottom of the piston rod of the hydraulic cylinder, and a bearing plate located at the bottom of the pressing plate on the top of the press frame.

[0006] The bottom of the press frame is equipped with a base plate, and the inner wall of the base plate has a groove. The inner wall of the groove is connected to a driven gear and a movable block via shafts. A ball bearing is provided on one side of the movable block. A dual-head motor is installed on the top of the base plate. The output shaft of the dual-head motor is fixedly connected to a drive shaft via a coupling. A drive gear is fixedly connected to the outer wall of the drive shaft. By setting up a press frame, support frame, pneumatic clamp, hydraulic cylinder, press plate, bearing plate, base plate, groove, driven gear, movable block, ball bearing, dual-head motor, drive shaft, and drive gear, it is convenient to drive the movable block to rotate, so that one end of the movable block moves to contact or away from the ground. When it moves away from the ground, the arc-shaped slope of the movable block can move through the ball bearing. When it contacts the ground, the contact area is increased, thus preventing movement and solving the problem of accidental slippage.

[0007] Furthermore, the base plate is connected to the press frame by bolts, and there are four grooves symmetrically distributed in pairs on the inner wall of the base plate, which facilitates the installation of the base plate.

[0008] Furthermore, the driven gear forms a linkage structure with the movable block through a shaft, and the driven gear meshes with the driving gear, which facilitates the rotation of the movable block.

[0009] Furthermore, one end of the movable block is provided with a flat end, the bottom of which is flush with the bottom of the lowest ball bearing, which facilitates support and positioning.

[0010] Furthermore, one end of the movable block is provided with an arc-shaped slope, and the ball bearing is located at the arc-shaped slope end of the movable block, which facilitates movement.

[0011] Furthermore, the bottom of the curved slope end of the movable block is higher than the bottom of its flat end, the ball bearings are rotatably connected to the movable block, and there are several ball bearings evenly distributed on the curved slope surface of the movable block, which further ensures the movement operation.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0013] (1) By setting up a press frame, support frame, pneumatic clamp, hydraulic cylinder, press plate, bearing plate, base plate, groove, driven gear, movable block, ball bearing, double-headed motor, drive shaft and drive gear, it is convenient to drive the movable block to rotate, so that the movable block drives one end of the plane to contact or move away from the ground. When it moves away from the ground, the arc-shaped slope of the movable block can move through the ball bearing. When it contacts the ground, the contact area can be increased, so that it cannot move and solves the problem of accidental slippage. Attached Figure Description

[0020] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 The present invention provides a technical solution: a press for easy-to-adjust bearing pressing, comprising a press frame 1, a support frame 2 fixedly connected to the top of the press frame 1, a pneumatic clamp 3 provided inside the top of the press frame 1 near the support frame 2, a hydraulic cylinder 4 installed on the top of the support frame 2, a pressing plate 5 fixedly connected to the bottom of the piston rod of the hydraulic cylinder 4, and a bearing plate 6 located at the bottom of the pressing plate 5 on the top of the press frame 1.

[0022] A base plate 7 is installed at the bottom of the press frame 1. A groove 8 is formed on the inner wall of the base plate 7. A driven gear 9 and a movable block 10 are connected to the inner wall of the groove 8 via shafts. A ball bearing 11 is provided on one side of the movable block 10. A double-headed motor 12 is installed at the top of the base plate 7. The output shaft of the double-headed motor 12 is fixedly connected to a drive shaft 13 via a coupling. A drive gear 14 is fixedly connected to the outer wall of the drive shaft 13. By setting up the press frame 1, support frame 2, pneumatic clamp 3, hydraulic cylinder 4, pressing plate 5, bearing plate 6, base plate 7, groove 8, driven gear 9, movable block 10, ball bearing 11, double-headed motor 12, drive shaft 13 and drive gear 14, it is convenient to drive the movable block 10 to rotate, so that one end of the movable block 10 is in contact with or away from the ground. When it is away from the ground, the arc-shaped slope of the movable block 10 can move through the ball bearing 11. When it is in contact with the ground, the contact area is increased, so it cannot move and the accidental slippage is solved.

[0023] Furthermore, the base plate 7 is connected to the press frame 1 by bolts, and there are four grooves 8 symmetrically distributed in pairs on the inner wall of the base plate 7, which facilitates the installation of the base plate 7.

[0024] Furthermore, the driven gear 9 forms a linkage structure with the movable block 10 through a shaft, and the driven gear 9 meshes with the driving gear 14, which facilitates the rotation of the movable block 10.

[0025] Furthermore, one end of the movable block 10 is provided with a flat end, the bottom of which is flush with the bottom of the lowest ball 11, which facilitates support and positioning.

[0026] Furthermore, one end of the movable block 10 is provided with an arc-shaped slope, and the ball bearing 11 is located at the arc-shaped slope end of the movable block 10, which facilitates movement.

[0027] Furthermore, the bottom of the curved slope end of the movable block 10 is higher than the bottom of its flat end, the ball bearing 11 is rotatably connected to the movable block 10, and there are several balls bearing 11 evenly distributed on the curved slope surface of the movable block 10, which further ensures the movement operation.

[0028] In use, the two dual-head motors 12 are first started, causing the two dual-head motors 12 to rotate through the two drive shafts 13, which in turn drive the four driven gears 14 to rotate. The four driven gears 14 then drive the four driven gears 9 to rotate through the shafts, causing the four driven gears 9 to rotate the four movable blocks 10. The four movable blocks 10 can effectively rotate on the ground by means of the ball bearings 11 set on their curved slopes. This causes one flat end of the movable block 10 to be either removed from or moved away from the ground. When it is moved away from the ground, the movable block 10 can move on the ground by means of the ball bearings 11, which facilitates the position adjustment of the press frame 1. When it is removed from the ground, the contact area is increased, and the ball bearings 11 are positioned by friction, preventing them from rotating and thus preventing accidental slippage and improving the stability after position adjustment.
