Description

Technical Field

[0001] The present application relates to the technical field of sliding bearing installation, and in particular to a sliding bearing installation device. Background Art

[0002] Sliding bearings are indispensable components in mechanical equipment. They carry bearing loads of rotation or linear motion, reduce friction and wear, and improve the efficiency and life of the equipment. They are widely used in various industrial equipment, especially under high load, low speed and high precision working conditions. They have high adaptability and excellent performance. The advantages are low noise, high load capacity and long life. The disadvantages are high friction, more heat, high lubrication requirements and high installation requirements. It is necessary to ensure the matching accuracy of the inner and outer sleeves and the uniform coating of the sliding layer. When installing the bearing seat, the centers of each bearing on the same transmission shaft should be on the same axis, and the coaxiality error should be within the specified range. This can prevent additional loads caused by the non-straight axis, thereby ensuring the stable operation of the bearing and the entire transmission system. The existing bearing installation device cannot position the bearing well, and cannot freely adjust the position of the positioning structure according to the size and size of the bearing, and cannot ensure complete verticality when pressing down vertically, resulting in low practicality. Utility Model Content

[0003] The purpose of the present application is to provide a sliding bearing installation device, which solves the problem that the existing bearing installation device proposed in the background technology cannot position the bearing well, cannot freely adjust the position of the positioning structure according to the size and size of the bearing, and cannot ensure complete verticality when pressed vertically, resulting in low practicality.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a sliding bearing installation device, comprising a base, a support frame, a pressure plate and a movable plate, a top side of the base is fixedly connected with a lower adjustment groove, the inner side of the lower adjustment groove is laterally rotatably connected with a No. 1 bidirectional screw rod, both sides of the surface of the No. 1 bidirectional screw rod are threadedly connected with a No. 1 threaded block, the outer wall of the No. 1 threaded block is fixedly connected with a folding rod, and the other end of the folding rod is fixedly connected with a lower clamping block, the top center of the lower adjustment groove is fixedly connected with a vertical adjustment groove, the inner side of the vertical adjustment groove is vertically rotatably connected with a threaded rod, the surface of the threaded rod is threadedly connected with a No. 2 threaded block, the outer side wall of the No. 2 threaded block is fixedly welded with a support frame, an upper adjustment groove is fixedly connected with the side wall of the support frame below, the inner side of the upper adjustment groove is rotatably connected with a No. 2 bidirectional screw rod, both sides of the surface of the No. 2 bidirectional screw rod are threadedly connected with clamping rods, and the surfaces of the clamping rods on the left and right sides facing each other are fixedly connected with upper clamping blocks, both sides of the bottom of the adjustment groove are fixedly connected with extension plates, and a movable plate is movably placed between the two extension plates.

[0005] In this technical solution, the bearing sleeve outside the bearing is placed in the center of the base, and the bearing body is placed in the center of the movable plate. Bearings of different sizes can be positioned through the upper clamping block, the lower clamping block, the No. 1 bidirectional screw and the No. 2 bidirectional screw. After the No. 1 motor is started, it drives the No. 1 bidirectional screw to rotate, so that the lower clamping block gradually approaches to clamp the bearing sleeve. The upper clamping block is manually rotated to drive the No. 2 bidirectional screw to rotate, so that the upper clamping block gradually approaches to clamp the main body of the bearing. The separate clamping allows the device to adapt to the positioning of bearings of different sizes, thereby improving the practicability of the device. At the same time, through the movable plate, screw The threaded rod and support frame can facilitate the installation of the bearing. After the upper clamp clamps the bearing body, the movable plate below is pulled out to make the bearing body suspended in the air. Then the No. 2 motor drives the threaded rod to rotate, causing the support frame to gradually descend, and the bearing body will move along with it, gradually approaching the bearing sleeve below, and finally reaching directly above the bearing sleeve. Then the electric push rod starts to extend, driving the pressure plate to move downward, pressing the bearing body into the bearing sleeve to complete the installation. It meets the installation requirements of bearings of different thicknesses. Because they are close enough and the two are always on the same vertical line, the installation process is more stable and accurate.

[0006] As an optional solution of the technical solution of the present application, an electric push rod is fixedly installed on the top of the support frame, and the lower telescopic end of the electric push rod passes through the support frame and is fixedly connected to the pressure plate.

[0007] As an optional solution of the technical solution of the present application, the right end of the second bidirectional screw rod passes through the upper adjustment slot and is fixedly connected to the torsion block.

[0008] As an optional solution of the technical solution of the present application, a No. 1 motor is fixedly installed on the right end of the lower adjustment groove, and the outer end of the transmission shaft of the No. 1 motor is fixedly connected to the right end of the No. 1 bidirectional screw rod.

[0010] As an optional solution of the technical solution of the present application, the surfaces of the upper clamping block and the lower clamping block are both provided with clamping grooves.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present application can position bearings of different sizes through the upper clamping block, the lower clamping block, the No. 1 bidirectional screw and the No. 2 bidirectional screw. After the No. 1 motor is started, it drives the No. 1 bidirectional screw to rotate, so that the lower clamping block gradually approaches to clamp the bearing sleeve. The upper clamping block is manually rotated to drive the No. 2 bidirectional screw to rotate, so that the upper clamping block gradually approaches to clamp the main body of the bearing. The separate clamping enables the device to adapt to the positioning of bearings of different sizes, thereby improving the practicality of the device.

[0013] 2. The present application can facilitate the installation of bearings through the movable plate, threaded rod and support frame. After the upper clamp clamps the bearing body, the movable plate below is pulled out to make the bearing body suspended in the air. Then the No. 2 motor drives the threaded rod to rotate, causing the support frame to gradually descend, and the bearing body will move along with it, gradually approaching the bearing sleeve below, and finally reaching directly above the bearing sleeve. Then the electric push rod starts to extend, driving the pressure plate to move downward, pressing the bearing body into the bearing sleeve to complete the installation, which meets the installation requirements of bearings of different thicknesses. Since they are close enough and the two are always on the same vertical line, the installation process is more stable and accurate. BRIEF DESCRIPTION OF THE DRAWINGS
