Problems solved by technology

[0006] In view of the above problems, the present invention provides an automatic spindle assembly equipment, which uses the lifting mechanism to carry the ring workpiece to move in the vertical direction, so that after the ring workpiece is heated and expanded, it can be directly and automatically assembled with the spindle through the lifting mechanism. The installation is designed to ensure the coaxiality between the annular workpiece and the main shaft during the process of assembly, and solves the technical problem of the reduction of matching accuracy caused by the secondary movement or manual assembly during the assembly process.

Embodiment 1

[0056] Such as Figures 1 to 11 As shown, a kind of spindle automatic assembly equipment includes a machine base 1 and an electro-permanent magnetic chuck 2. The electro-permanent magnetic chuck 2 is horizontally installed on the installation table 11 at the top of the machine base 1. The electro-permanent magnetic chuck 2 A mounting slot 21 for clamping and fixing the vertically arranged main shaft 101 is provided at the position of the axis, and also includes:

[0057] A lifting mechanism 3, the lifting mechanism 3 is installed on the installation table 11, and it is loaded with an annular workpiece 102 coaxially arranged with the main shaft 101 and slides vertically to fit the main shaft 101;

[0058] a heating mechanism 4, the heating mechanism 4 is installed on the installation table, it is adjacent to one side of the lifting mechanism 3, and it heats around the annular workpiece 102; and

[0059] An induction detection mechanism 5, the induction detection mechanism 5 is...

Embodiment 2

[0084] Figure 12 It is a structural schematic diagram of Embodiment 2 of an automatic spindle assembly equipment of the present invention; Figure 12 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. This embodiment two and figure 1 The difference of the shown embodiment one is:

[0085] Such as Figure 12 As shown, a fixed installation opening 3163 is opened on the side installation surface 3162 perpendicular to the installation surface 3161 on the slider 316, and a fixed installation opening 3163 is opened on the installation back surface 3164 parallel to the installation surface 3161 on the slider 316. There are mounting notches 3165.

[0086] It should be noted that the sliding part 316 is used to install the bearing plate 32, the heating coil 42, ...

Embodiment 3

[0088] Embodiment 3 of the present invention is described with reference to Embodiment 1 to Embodiment 2, an assembly method using the spindle automatic assembly equipment described in any one of Embodiment 1 to Embodiment 2.

[0089] Such as Figure 13 shown, including the following steps:

[0090] Step 1, the main shaft is installed, the end of the main shaft 101 and the annular workpiece 102 are fitted and installed vertically upwards, so that the lower end of the main shaft 101 is vertically inserted into the installation groove 21 of the electro-permanent magnetic chuck 2, and the distance on the induction detection mechanism 5 After the sensor 53 detects that the verticality of the main shaft 101 is qualified, the main shaft 101 is adsorbed and fixed by the electro-permanent magnetic chuck 2;

[0091] Step 2: Install the ring-shaped workpiece. After the main shaft 101 is mounted and fixed, place the ring-shaped workpiece 102 on the loading plate 32 of the lifting mechan...

Abstract

The invention relates to the technical field of spindle assembly, and specifically discloses an automatic spindle assembly device and a spindle assembly method using the device, which uses a lifting mechanism to carry a ring-shaped workpiece to move in the vertical direction, so that after the ring-shaped workpiece is heated and expanded, It can be installed directly with the main shaft through the lifting mechanism to ensure the coaxiality between the annular workpiece and the main shaft during the assembly process, and solve the problem of lower matching accuracy caused by secondary movement or manual assembly during the assembly process. Technical problems, and by setting the induction detection mechanism, the temperature and dimensional change of the ring workpiece during the thermal expansion process are monitored by the induction detection mechanism, so as to ensure that the expansion of the ring workpiece meets the assembly requirements, and at the same time avoid the transitional thermal expansion of the ring workpiece, ensuring The strength of the ring workpiece itself.

Description

technical field [0001] The invention relates to the technical field of spindle assembly, in particular to an automatic spindle assembly device and a spindle assembly method using the device. Background technique [0002] In the assembly process of mechanical equipment, especially in the assembly process of motor equipment, the interference fit installation between the main shaft and the annular workpiece is often encountered, and the installation process is as introduced in the background technology of the patent document CN103078454B Mostly, the ring workpiece is heated and expanded or the shaft workpiece is heated and expanded, and then the fitting installation or embedded installation is performed. [0003] However, in the existing assembly process, the main shaft or the annular workpiece is heated and expanded, and then assembled after transfer, and whether the expansion size of the workpiece meets the assembly standard, the coordination between the shaft workpiece and t...
