Problems solved by technology

At present, there are two ways of distributing seat rings. One is fully automatic, which uses CNC robots to control the movement of the distributor. The advantages are reliable action and accurate positioning; the disadvantages are high equipment costs and operation and maintenance costs.
The other is full manual distribution, which uses manual methods to install the seat ring to the press-fitting head. The disadvantage is that special personnel are required to take care of it, which takes up labor and leads to increased labor costs.

Embodiment 1

[0034] Such as figure 1As shown, the distribution mechanism includes a trident pipe 1, the trident pipe 1 has a feed branch pipe 11 and two discharge branch pipes 12, the outlet of the feed branch pipe 11 is connected to the inlet of the two discharge branch pipes 12 and formed at the junction A joint part 3 is provided with a distribution frame 2 hinged on the inner wall of the trident pipe 1 at the joint part 3, and the distribution frame 2 can be intermittently opened and closed by the inertial force of the valve seat ring 9 when it descends. Inlet, before using this distribution mechanism, the two discharge branch pipes 12 of the trident pipe 1 are respectively aligned with the two valve seat ring installation holes of the engine block, when the first valve seat ring 9 descends from the feed branch pipe 11 , the distribution rack 2 blocks one of the discharge branch pipes 12, when the second valve seat 9 descends from the feed branch pipe 11 to the junction 3, due to the a...

Embodiment 2

[0039] Such as image 3 As shown, the distribution mechanism includes a trident pipe 1, the trident pipe 1 has a feed branch pipe 11 and two discharge branch pipes 12, the outlet of the feed branch pipe 11 is connected to the inlet of the two discharge branch pipes 12 and formed at the junction A combination part 3, a baffle plate 5 is arranged inside the combination part 3, and the baffle plate 5 is connected to a drive assembly 6 capable of intermittently driving the baffle plate 5 to open and close the inlet of the discharge branch pipe 12. Before using the distribution mechanism, The two discharge branch pipes 12 of the trident pipe 1 are respectively aligned with the two valve seat ring mounting holes of the engine block. When the first valve seat ring 9 descends from the feed branch pipe 11, the drive assembly 6 drives the baffle plate 5 Block one of the discharge branch pipes 12, when the second valve seat ring 9 descends from the feed branch pipe 11, the drive assembly...

Embodiment 3

[0043] Such as Figure 4 with Figure 5 As shown, the present embodiment is based on embodiment one or embodiment two, and the valve seat ring 9 is a gasket installed on the intake valve and the outlet valve on the engine block. Taking a four-cylinder engine as an example, If each cylinder is correspondingly provided with two intake valves and one outlet valve, in order to install all valve seat rings 9 at one time, a plurality of above-mentioned trident pipes 1 can be connected. In this embodiment, three Trident pipe 1 is taken as an example to illustrate the principle of this scheme: the feed branch pipes 11 of two trident pipes 1 are connected with the two discharge branch pipes 12 of the other trident pipe 1 respectively, and the three trident pipes are generally connected by welding. Connect the pipes 1 and let them all communicate with each other. Align the four outlet pipes 12 at the bottom with the valve seat ring mounting holes on the engine block, and put down the f...

Abstract

The invention belongs to the technical field of machinery and provides a valve seat ring distributing mechanism which solves the technical problem of complex structure, high using cost and the like of manipulators adopted on existing engine cylinders for distributing valve seat rings. The valve seat ring distributing mechanism comprises a Y-shaped pipe allowing the valve seat rings to pass, the Y-shaped pipe is provided with a feeding branched pipe and two discharging branched pipes, a joint portion is formed at the joint of the feeding branched pipe and the discharging branched pipes, a distribution frame hinged on the inner wall of the Y-shaped pipe is arranged at the joint portion, under inertia force action, the distribution frame can intermittently open and close inlets of the discharging branched pipes, or a retaining plate is arranged in the joint portion and connected with a driving component intermittently driving the retaining plate to open and close the inlets of the discharging branched pipes. The valve seat ring distributing mechanism has the advantages of simple structure, low using cost and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a distribution mechanism for valve seat rings. Background technique [0002] With the rapid development of the automobile production industry, the competition among major automobile enterprises is becoming increasingly fierce, and automobiles have entered the stage of mass production. The production efficiency and production cost in each production process determine the important factors for automobile enterprises to gain a foothold. [0003] During the machining process of the cylinder head, it is necessary to carry out the press-fitting work of the guide pipe and the valve seat ring. During the press-fitting process, the valve seat ring needs to be distributed so that it can enter the correct position to meet the press-fitting requirements. At present, there are two ways to distribute seat rings. One is fully automatic, which uses CNC robots to control the movement of the distr...
