Cavity internal screw automatic press fitting equipment

Abstract

The invention relates to cavity internal screw automatic press fitting equipment. The cavity internal screw automatic press fitting equipment comprises a machine body, a table top, a floating plier body assembly, a tool assembly, and a plier body supporting block, wherein the floating plier body assembly is connected with the machine body, and is provided with a C-shaped pressure head; the tool assembly is arranged below the floating plier body assembly, and is connected with the table top; the tool assembly is provided with a circular force bearing block; the circular force bearing block is provided with a rotating shaft; the rotating shaft is connected to a rotary cylinder; a first floating block is arranged on the circular force bearing block; a lower mold is arranged on the first floating block; a workpiece press-fitting hole allowing a workpiece to be accommodated is formed in the lower mold; a lower side force bearing block which corresponds to the first floating block is arranged below the disc force bearing block; and the plier body supporting block is arranged below the lower side force bearing block. The cavity internal screw automatic press fitting equipment disclosed bythe invention is large in expansibility, and putting into production and increasing of the later stage products are convenient; and besides, automatic press fitting and process monitoring of a plurality of screws are realized; and the cavity internal screw automatic press fitting equipment is also suitable for press fitting of other cavity type section material spare parts, and a series of stepsof single-time feeding, automatic pressing in, process monitoring and the like are realized.

Description

technical field [0001] The invention relates to an automatic press-fitting device for screws in a cavity. Background technique [0002] See attached figure 1 As shown, in the automatic press-fitting process of the cavity-like parts shown in the figure, two screws are manually loaded into the cavity at a time, and then the equipment is automated to realize the press-fitting process. The tooling needs to be designed in a modular manner to switch other tooling as a whole . See attached figure 2 The press-in process of screws and plates shown, for this type of workpiece, the existing common practice is to insert a long strip of pressure block between the cavity upper layer material and the cavity lower layer material in the cavity of the part as a whole load bearing On the other hand, when pressing, the forming die will squeeze the plate to form a pit so that the screw can be embedded, and the screw is pressed into the slightly smaller hole of the plate to achieve material e...

Problems solved by technology

[0003] This form is limited by the structure of the elongated pressure block, and both ends need to bear force. At the same time, because the screws will be embedded in the material during the press-fitting process, the workpiece will sink as a whole. If one side is press-fitted (not two points together), the material on the left side will sink and be embedded in the material, which will cause the material on the right side to deform, which will lead to the overall deformation of the workpiece.

If press-fitting at the same time, there will also be the following disadvantages: too much pressure, uneconomical, poor equipment expansion, because two simultaneous press-fitting, the pressure displacement process of a single screw cannot be accurately monitored, and the quality cannot be guaranteed
