Problems solved by technology

This installer can avoid knocking during installation, but it can only be used to install the pulley, not the bearing, and it also includes an oil hydraulic jack, which causes the installer to be heavy in weight, complex in structure and high in cost

Embodiment 1

[0028] A disassembly and installation tool, such as Figures 1 to 4 As shown, it includes a screw mandrel 1 and a turntable 2, wherein the screw mandrel 1 and the turntable 2 are connected by threads. One end of the screw mandrel 1 is a top 11, and the root of the top 11 is a quadrangular prism with four process planes 13 or a hexagonal prism with six process planes 13. crafting slot. The quadrangular prism or hexagonal prism is used for clamping by tools such as a wrench. The other end of the screw mandrel 1 is a threaded connecting rod 12, which is used to fix the above screw mandrel on the shaft on which the pulley or the bearing needs to be installed in a threaded manner when the pulley or the bearing is installed. Two or more process planes 13 arranged symmetrically are arranged near the threaded connecting rod 12 of the screw 1; a boss 21 is provided on the side of the central hole of the turntable 2 near the threaded connecting rod 12, And the turntable 2 also has tw...

Embodiment 2

[0032] On the basis of Embodiment 1, the turntable 2 in this embodiment adopts the form with bosses 21 on both sides, such as Figure 5 shown. At this time, at least one of the inner holes of the turntable 2 and the two bosses 21 is an inner hole with a thread matched with the screw mandrel 1, and the diameters of the remaining inner holes are all larger than the threaded major diameter of the threaded inner hole. , so as to ensure that the thread fit between the turntable 2 and the screw mandrel 1 will not be affected. A better solution is to select only one boss 21 as the threaded inner hole, which is the easiest to process.

Embodiment 3

[0034] On the basis of the foregoing embodiments, the boss 21 may also be a boss whose peripheral wall is composed of discontinuous two or more equal-height parts. Such as Image 6 Shown as the peripheral wall of the boss is four parts of equal height evenly distributed around the central hole of the turntable 2 . The boss 21 of this form cannot be threaded, so it is necessary to process threads in the center hole of the turntable 2, or to set a boss with a threaded hole on the other side of the turntable 2. The peripheral wall of the boss 21 may be two or more discontinuous parts of equal height approximately symmetrical to the central hole of the turntable. During work, these equal-height parts can also be supported on the pulleys or bearings that need to be installed, so as to achieve the purpose of the present invention.

Abstract

The invention discloses an assembling and disassembling tool, and aims to provide a tool for manually assembling and disassembling general-type belt pulleys and bearing-type pressed-on mating parts. The assembling and disassembling tool comprises a screw rod and a rotary plate in thread connection with the screw rod, wherein one end of the screw rod is provided with a core clamper; two or more processing planes are symmetrically arranged in the circumferential direction of the root of the core clamper; the other end of the screw rod is provided with a thread connecting rod; two or more processing planes are symmetrically arranged in the circumferential direction of the screw rod close to the thread connecting rod; the end face on one side or two sides of the rotary plate is provided with a boss which is coaxial with the rotary plate and provided with through holes; and the end face of the rotor plate is also provided with two or more through holes which are symmetrically distributed. The assembling and disassembling tool can be used for assembling or disassembling belt pulleys and bearing-type pressed-on mating parts.

Description

technical field [0001] The invention relates to a dismantling and installing tool, in particular to a manually operated dismantling and installing tool for a pulley or a bearing. Background technique [0002] A puller is a common machinery maintenance tool used to remove pulleys, bearings, or similar press-fit fittings. For example, the Chinese Utility Model Patent Application No. 200510062032.5 discloses a puller with claws and a threaded push rod. When this tool is used, the claw is used to hook the part to be disassembled, and then the pointed end of the ejector rod is placed on the shaft, and the ejector rod or the claw support is rotated with the tool to remove the part. The disadvantage of this puller is that it cannot be used to install parts such as pulleys and bearings. [0003] Pulleys or bearings are usually fixed on the shaft by means of interference fit, and such pulleys or bearings are usually installed by knocking. The disadvantage is that it is easy to cau...
