Description

Technical Field

[0001] This invention relates to the field of automotive engine assembly technology, specifically to an open-type conduit valve seat press-fitting machine and its operating method. Background Technology

[0002] The existing pipe and valve seat press-fitting machine tool structure is generally a square frame structure. The pipe and valve seat press-fitting bracket is mounted on the machine bed, and a top cover connects the pipe and valve seat press-fitting bracket from above. This is a relatively traditional workstation setting.

[0003] Furthermore, due to the overly complex structure of the machine tool, the space above the machine tool is occupied, and during press fitting, the workpiece has little room to move when it enters the machine tool for processing, which is not conducive to workpiece processing.

[0004] Furthermore, the automatic feeding system for guide tubes and valve seats is usually located above the machine tool, and the top cover also affects the arrangement of the automatic feeding system for guide tubes and valve seats.

[0005] In the current environment where automated machine tools are widely used, this setup is structurally complex and needs optimization. To address this, the present invention proposes an open-type conduit valve seat press-fitting machine and its operating method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an open conduit valve seat press-fitting machine and its operating method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an open conduit valve seat press-fitting machine tool and its operating method, wherein the open conduit valve seat press-fitting machine tool structure includes:

[0008] The bed connecting plate is a rectangular flat plate structure and is fixedly installed on the press-fitting machine.

The front and rear sides of the conduit press-fit bracket and the valve seat press-fit bracket are provided with horizontal threaded holes, and the inner side of the side connecting plate is provided with a vertical threaded hole. The horizontal mounting holes are correspondingly set with the horizontal threaded holes, and the vertical mounting holes are correspondingly set with the vertical threaded holes. The connecting key is positioned at the position of the horizontal threaded hole by a horizontal positioning bolt, and the connecting key is positioned at the position of the vertical threaded hole by a vertical positioning bolt.

[0017] Preferably, the horizontal mounting holes and the vertical mounting holes on the connecting key are staggered.

[0018] Preferably, a positioning groove is provided on the side connecting plate at the position of the longitudinal threaded hole, the end of the connecting key is embedded in the positioning groove, and the width of the positioning groove matches the thickness of the connecting key.

[0021] Step 2: Assembly process of valve seat press-fit bracket. During the assembly process of the valve seat press-fit bracket, the valve seat press-fit bracket is fixed to the bed connecting plate.

[0022] Step 3: Assembly of the side connecting plate. During the assembly of the side connecting plate, the workers position and fix the front and rear sides of the side connecting plate to the conduit press-fit bracket and the valve seat press-fit bracket, respectively.

[0023] Step 4: Assembly process of the conduit material channel. In the assembly process of the conduit material channel, the conduit material channel support is first fixed on the conduit press-fit support, and then the conduit material channel is fixed on the conduit material channel support.

[0024] Step 5: Assembly of the valve seat material channel. In the assembly of the valve seat material channel, the valve seat material channel bracket is first fixed on the valve seat press-fit bracket, and then the valve seat material channel is fixedly installed.

[0037] Please see Figure 1-4 The present invention provides the following four preferred embodiments: Example 1

[0038] An open-type conduit valve seat press-fitting machine and its operating method are disclosed. The open-type conduit valve seat press-fitting machine includes a bed connecting plate 1, a conduit press-fitting bracket 2, a valve seat press-fitting bracket 3, a side connecting plate 4, a conduit material channel 6, and a valve seat material channel 8. The bed connecting plate 1 is a rectangular flat plate structure and is fixedly installed on the press-fitting machine. The conduit press-fitting bracket 2 is fixed on the front side of the bed connecting plate 1, and the valve seat press-fitting bracket 3 is fixedly installed on the rear side of the bed connecting plate 1. A set of side connecting plates 4 are symmetrically arranged, and the front and rear sides of the side connecting plates 4 are respectively connected to the conduit press-fitting bracket 2 and the valve seat press-fitting bracket 3. A groove is opened in the middle part of the side connecting plate 4, and a conduit material channel bracket 5 and a valve seat material channel bracket 7 are fixedly installed on the bottom surface of the groove. The conduit material channel 6 is fixedly installed on the conduit material channel bracket 5, and the valve seat material channel 8 is fixedly installed on the valve seat material channel bracket 7.

[0039] The bed connecting plate 1, the guide tube pressing bracket 2, and the valve seat pressing bracket 3 are all positioned and installed using bolts. By setting up an open guide tube and valve seat pressing machine tool structure composed of the bed connecting plate 1, the guide tube pressing bracket 2, the valve seat pressing bracket 3, the side connecting plate 4, the guide tube material channel 6, and the valve seat material channel 8, and by creating a groove in the middle part of the side connecting plate 4, the traditional top cover connecting plate is eliminated. Instead, the side connecting plate 4 connects the guide tube pressing bracket 2 and the valve seat pressing bracket 3, allowing the space above the machine tool to be completely open. This avoids interference with the guide tube and valve seat feeding system and the workpiece processing action, thereby optimizing the machine tool structure, making the machine tool structure simpler, and increasing maintenance space.
