A linear bearing press-fitting device and press-fitting method for compound probe assembly

Abstract

The invention provides a linear bearing press-fitting device for assembling a composite probe. The linear bearing press-fitting device comprises a bottom plate, on which a bearing guiding mechanism, asupport frame for supporting paper tubes and a stopper for limiting the paper tubes are arranged in sequence, wherein the bearing guiding mechanism is movably connected with a pressing rod for pushing parts pressed in the paper tubes to move horizontally, the end of the pressing rod is connected with a lever transmission mechanism for driving the pressing rod to move horizontally, and the pressing rod, the paper tubes on the support frame and the stopper are coaxially arranged. The linear bearing press-fitting device has a simple structure; the lever transmission mechanism is manually controlled to drive the pressing rod to press the press-fitting parts in the paper tubes under the guiding action of the bearing guiding mechanism, thereby reducing the press-fitting work intensity, improving the smoothness of the press-fitting action, and completing a press-fitting task of longer stroke; and two operations of slag chamber assembly process of the composite probe can be completed throughone press-fitting process, thereby improving the efficiency of press-fitting assembly.

Description

technical field [0001] The invention belongs to the technical field of production auxiliary equipment for press-fit assembly, and in particular relates to a linear bearing press-fit device and a press-fit method for compound probe assembly, which are suitable for internal assembly positioning with a long press-fit stroke. Background technique [0002] In the assembly of some parts, due to the influence of the press-fitting process and the assembly position, the press-fitting stroke is required to be longer, and the parts are assembled inside and outside the shape, and the press-fitting stroke is not easy to observe and control during automatic press-fitting. Such as figure 1 As shown, in the slag chamber positioning process of the composite probe, the slag chamber 2 and the paper tube 1 are at the drainage port 3 as the reference point for assembly. When assembling, when the drainage ports 3 of the two are aligned, put the sleeve into the The dislocation of the two is limit...

Problems solved by technology

[0002] In the assembly of some parts, due to the influence of the press-fitting process and the assembly position, the press-fitting stroke is required to be longer, and the parts are assembled internally and externally, and the press-fitting stroke is not easy to observe and control during automatic press-fitting

like figure 1 As shown, in the slag chamber positioning process of the composite probe, the slag chamber 2 and the paper tube 1 are at the drainage port 3 as the reference point for assembly. When assembling, when the drainage ports 3 of the two are aligned, put the sleeve into the The dislocation of the two is limited to realize the assembly limit and shape; at the same time, the sealing piece 4 at the right end of the slag chamber 2 is fixed by squeezing the compression spring 5 with the adjustment tube 6 to seal and shape the slag chamber 2. In the slag chamber assembly process, the process The operation includes two items: "fixing the adjusting tube 6 with nails, pressing and positioning the slag chamber". Among them, since the assembly position of the slag chamber 2 is in the middle of the paper tube 1, the press-fitting stroke is long, and due to the material of the paper tube, the paper tube 1 The dimensional accuracy of the drainage port is not high, and it is not convenient to use a fixed-length automatic press-fit device to realize the press-fit task of the slag chamber 2
