Easy-to-process automotive engine block fixture

Abstract

The invention discloses an automobile engine cylinder body clamp facilitating automobile engine cylinder body machining. The clamp comprises a supporting board, a pair of first screw rods, a pair of first through grooves, two pairs of lantern rings, a pair of connecting rods, a pair of fixing rods, a pair of guide columns, a driving gear, a pair of driven gears and two pairs of air cylinders; eachpair of lantern rings comprise the first lantern ring and the second lantern ring, wherein each first lantern ring sleeves the upper part of the corresponding first screw rod and is in threaded connection with the upper part of the corresponding first screw rod, and each second lantern ring sleeves the lower part of the corresponding first screw rod and is in threaded connection with the lower part of the corresponding first screw rod; one ends of the connecting rods are horizontally connected with the first lantern rings corresponding to the first screw rods, and the other end of each connecting rod is vertically downwards connected with a horizontal pressing plate; one sides, close to the first screw rods, of the pressing plates are sunken inwards to form second through grooves; and thelower parts of the guide columns are just clamped in the first through grooves, and the upper parts of the guide columns are just clamped in the second through grooves. The clamp has the advantages of being consistent in clamping force, reliable and stable in clamping, suitable for positioning holes with different sizes and the like, and can be widely applied to the technical field of automobileengine cylinder body clamps.

Description

technical field [0001] The invention relates to the technical field of automobile engine cylinder block clamps, more specifically, the invention relates to an easy-to-process automobile engine cylinder block clamp. Background technique [0002] Fixtures play a very important role in the processing and production of automobile engine blocks, and automobile engine blocks are one of the core components of automobiles. In the process of clamping the automobile engine block with the traditional fixture, there are problems such as inconsistent clamping force, unreliability, instability, etc., and it is easy to generate partial load, resulting in low machining accuracy of the automobile engine block. Manually debugging the fixture, It will lead to low processing efficiency and waste of human resources. Moreover, the size of the locating pins in the fixture is fixed, causing the locating pins to be unable to adapt to the positioning holes of different sizes of the automobile engine...

Problems solved by technology

In the process of clamping the automobile engine block with the traditional fixture, there are problems such as inconsistent clamping force, unreliability, instability, etc., and it is easy to generate partial load, resulting in low machining accuracy of the automobile engine block. Manually debugging the fixture, It will lead to low processing efficiency and waste of human resources

Moreover, the size of the locating pins in the fixture is fixed, causing the locating pins to be unable to adapt to the positioning holes of different sizes of the automobile engine block, resulting in unreliable positioning; to match a variety of locating holes of different sizes, it is necessary to be equipped with multiple sizes of positioning holes. Positioning pins cause waste of resources
