Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] Such as figure 1 , 2 And shown in 3, a kind of installation hole drilling tool of automobile exhaust manifold inlet joint mainly consists of horizontal base plate 1, door beam 2, cylinder 3, first positioning pin 4, second positioning pin 5, lower wedge-shaped block 6. The guide block 7, the upper wedge block 8, the vertical lifting rod 9, the door-shaped part 10 and the tight plate 11 are formed. Wherein, the horizontal base plate 1 is a rectangular plate, and its material is Q235, and the horizontal base plate 1 is fixed on the workbench of the vertical drilling machine through T-bolts and a pressure plate. The upper surface of the horizontal base plate 1 is vertically fixed with a portal beam 2 and a cylinder 3, wherein the lower ends of the two vertical sides of the portal beam 2 are fixed to the upper surface of the horizontal base plate 1, and ...

Abstract

The invention discloses an automobile exhaust manifold air inlet connector installation hole drilling tool. A right-angled n-shaped beam and an air cylinder are fixed to the upper face of a horizontal bottom plate. A drill bit via hole is formed in the horizontal edge of the right-angled n-shaped beam. A first positioning pin and a second positioning pin are arranged on the lower surface of the horizontal edge of the right-angled n-shaped beam. The air cylinder is horizontally arranged. A lower wedge block is fixed to the end of a piston rod of the air cylinder. The inclined plane on the top of the lower wedge block adapts to the inclined plane of the bottom of an upper wedge block. The plane on the top face of the upper wedge block is fixed to the bottom face of a vertical lifting rod. The middle of the vertical lifting rod is in sliding fit with the via hole in the horizontal edge of the right-angled n-shaped beam. The right-angled n-shaped beam is installed on the upper face of the horizontal bottom plate. The air cylinder which is originally arranged vertically is adjusted to be arranged horizontally so that the air cylinder can push a jacking plate to achieve upward jacking through small pressure, and the pressure specification of the air cylinder is greatly reduced; in addition, the force of a drill bit directly acts on the upper wedge block during drilling, the jacking force and reliability of the air cylinder can be ensured, and the piston rod of the air cylinder is prevented from shaking violently.

Description

technical field [0001] The invention belongs to the field of automobile exhaust manifold processing, and relates to a tool for drilling installation holes of intake joints of automobile exhaust manifolds. Background technique [0002] The exhaust manifold is an important part of the car engine system, and there are some installation holes for the intake joints on it. In order to drill these intake joint installation holes, a horizontal bottom plate is currently set on the workbench of the vertical drilling machine, and the upper surface of the horizontal bottom plate is vertically provided with a portal beam and a large cylinder, wherein the piston of the large cylinder The rod is upwards, and the exhaust manifold to be drilled can be pressed against the bottom surface of the horizontal edge of the portal beam, so that the drill bit can go up and down to drill holes. [0003] The defect of existing structure is: in order to guarantee reliable jacking force, need to adopt th...
