Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, in t...

Abstract

The invention discloses an engine cylinder cover machining clamp which comprises a pedestal, a clamping mechanism and a lifting tray, wherein a first telescopic cylinder is arranged on the pedestal; apositioning surface and a positioning pin are also arranged on the pedestal; the clamping mechanism is connected with the first telescopic cylinder; the first telescopic cylinder drives the clampingmechanism to operate; the lifting tray is arranged above the pedestal; the bottom of the lifting tray is connected with a second telescopic cylinder arranged on the pedestal; a first opening, a secondopening, a guide strip and a limiting piece are arranged on the lifting tray; the guide strip is arranged in the push-in direction of a workpiece; the limiting piece is arranged on the side, perpendicular to the push-in direction of the workpiece, of the lifting tray; the positioning pin penetrates through the first opening; the second opening is used for exposing the positioning surface. The clamp is used for automatically clamping a cylinder cover instead of manual clamping by a worker, so that the machining assisting time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of automobile engine manufacturing, in particular to an engine cylinder head processing fixture. Background technique [0002] The cylinder head is a very important part of the engine. In the processing process, the position and flatness of the cylinder head are highly required, and there are holes on the cylinder head that require extremely high precision. Therefore, the design of the fixture used in engine cylinder head processing is very important, and its processing accuracy and accuracy must be guaranteed. stability. The machining of the engine cylinder head is usually completed on a horizontal boring and milling machining center. When the degrees of freedom in all directions are limited, the process positioning hole of the cylinder head is used to position, and then the top surface of the cylinder head is clamped. Since the design basis of the top and bottom surfaces is the positioning hole, the accu...
