Self-adaptive press-fitting machine, automatic press-fitting system and press-fitting method thereof

Abstract

The invention discloses a self-adaptive press-fitting machine, an automatic press-fitting system and a press-fitting method thereof. The self-adaptive press-fitting machine comprises a pressure head and a driving device for driving the pressure head to move in a first direction and a second direction in a reciprocating mode, the pressure head is connected with the driving device through a coaxiality fine adjustment device. According to the scheme, the design is ingenious, the structure is simple, and the coaxiality fine adjustment device is arranged between the pressure head and the driving device, so that the pressure head can swing slightly with respect to the driving device; when press fitting is carried out, if a column-shaped body and a hole or a groove are not in a co-axial state, the column-shaped body clamped by the pressure head can be coaxial with the hole or the groove through slight swinging of the pressure head, so that the coaxiality is improved, and smooth press fittingis facilitated; and meanwhile, the damage of the column-shaped body or a workpiece easily caused by direct rigid pressing can be avoided, and the safety of press fitting is guaranteed.

Description

technical field [0001] The invention relates to the field of press-fitting equipment, in particular to an adaptive press-fitting machine, an automatic press-fitting system and a press-fitting method thereof. Background technique [0002] At present, in the field of automatic assembly production lines of automobile engines and new energy motors, there are often assembly operations that need to press-fit the first component into the second component. During assembly, the second component is usually placed on a pallet, and the pallet follows the conveyor line (Roller line) After being transported to the press-fitting position, the No. 1 component is axially pressed into the No. 2 component on the pallet by the press-fitting machine. [0003] In a common press-fitting machine, the indenter is fixedly connected to the power structure that drives it to press, or the indenter can float in the axial direction. At this time, if the No. Make the No. 1 component and No. 2 component ad...

Problems solved by technology

[0003] In a common press-fitting machine, the indenter is fixedly connected to the power structure that drives it to press, or the indenter can float in the axial direction. At this time, if the No. Make the No. 1 component and No. 2 component adjusted to the coaxial structure, and the large press-fitting force can easily cause hard contact between the No. 1 component and the hole or groove on the No. This kind of problem is more obvious during the press-fitting, which seriously affects the quality of the press-fitting, and the fact that the two are not coaxial also increases the difficulty of the press-fitting

[0004] At the same time, the No. 1 component needs to be placed into the hole or groove of the No. 2 component before press-fitting. Generally, the loading work is done manually or by a robot. Manual loading is labor-intensive and there are certain safety hazards; and The manipulator needs to add the manipulator and the structure that drives it to move separately, which increases the component cost of the equipment; in addition, the conventional manipulator basically clamps by applying force from the outer wall of the workpiece, and for hollow pins and other very small volume For thin-walled parts, conventional pneumatic grippers are difficult to control the clamping force, and it is easy to cause deformation of the hollow pin due to excessive clamping force, which affects the use; while the clamping force is
