Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the two camshaft oil holes are difficult to be clamped at one time on the existing equipment to realize the chamfering operation, and the chamfering can only be done manually, and the chamfering quality is poor and the chamfering efficiency is low. Insufficient, to provide a cylinder head camshaft oil hole chamfering device that realizes chamfering operation in one clamping, has better chamfering quality and higher chamfering efficiency

Embodiment Construction

[0015] The present invention will be further described below with reference to the drawings.

[0016] As attached figure 1 , Attached figure 2 Shown: a cylinder head camshaft oil hole chamfering device, comprising a support 2 with two upper side plates 21, a cross beam 3 with an arc-shaped sliding groove 31 and two ends connected with an upper side plate 21, It has a chamfering mechanism and a rotation angle limiting mechanism of the slider 4 that are matched with the arc-shaped sliding groove 31.

[0017] In this embodiment, the cross beam 3 includes two supporting plates 32 whose ends are each screwed to the side ends of an upper side plate 21; each arc-shaped sliding groove 31 is located on a supporting plate 32 and penetrates the supporting plate. The two sides of 32; the arc-shaped sliding groove 32 takes the intersection of the axes of the camshaft oil holes 17 of the two cylinder heads 16 as the axis.

[0018] The chamfering mechanism includes a pneumatic drill 5 with an up...

Abstract

The invention relates to the field of manufacturing of automotive engine cylinder heads, in particular to a cylinder head camshaft oil hole chamfering device. The cylinder head camshaft oil hole chamfering device comprises a support, a crossbeam, a chamfering mechanism and a corner limit mechanism, wherein the support is provided with two upper side plates, the crossbeam with each end connected with one upper side plate is provided with a circular arc sliding groove, and the chamfering mechanism is provided with a slider matched with the circular arc sliding groove. When the cylinder head camshaft oil hole chamfering device is used, a cylinder head is placed in the support, the chamfering mechanism is pulled, the corner limit mechanism is used to limit, and the chamfering mechanism chamfers one camshaft oil hole of the cylinder head; the chamfering mechanism is pulled, the corner limit mechanism is used to limit, and the chamfering mechanism chamfers the other camshaft oil hole of the cylinder head. The cylinder head camshaft oil hole chamfering device achieves chamfering operation by one-time clamping, and is good in chamfering quality and high in chamfering efficiency.

Description

Technical field [0001] The invention relates to the manufacturing field of cylinder heads of automobile engines, in particular to a cylinder head camshaft oil hole chamfering device. Background technique [0002] The utility model of Chinese Patent Announcement No. CN201934165U discloses an engine cylinder head camshaft pressure lubricating oil hole, including a cylinder head cover surface. The cylinder head cover surface is provided with spark plug holes, tappet holes and water plugging holes. The cylinder head cover surface A camshaft hole is made at both ends of the shaft hole, a tile cover is arranged on the shaft hole, a camshaft is installed between the camshaft hole and the tile cover, and a pressure lubricating oil hole is made in the camshaft hole. The traditional cylinder head is provided with two camshaft oil holes arranged horizontally and the angle between the two axes is 15 to 21 degrees as shown in the figure; burrs are often present after the camshaft oil holes ar...
