Description

Technical Field

[0001] The present application relates to the technical field of vehicle parts processing equipment, and in particular to a cylinder head blank positioning and clamping device. Background Art

[0002] The diesel engine cylinder head is an important component of the internal combustion engine and is a typical box-type part.

[0003] The first processing procedure of the diesel engine cylinder head requires the blank surface to be used as the positioning reference. Since the blank itself has a large dimensional tolerance, it is generally processed by marking first and then processing. When marking, the operator needs to use a temporary assembly and adjustment marking tool such as a shim and a movable ejector to align the workpiece, and use a marking needle to determine the processing position on the workpiece according to the blank reference surface, the reserved processing allowance of the hole, and the relative size. During processing, first align the cylinder head roughly and place it on the machine tool fixture, and then determine the numerical values ​​of the three coordinates of the height, length, and width of the workpiece along the marking reference. When the numerical difference between the two points does not meet the requirements, use a small hammer to tap and fine-tune, or adjust the positioning block by padding with gaskets of different specifications until the numerical difference meets the requirements, and then start the machine tool for processing.

[0004] However, each blank needs to be scribed, and each time the scriber is required to temporarily assemble and adjust the scriber tooling with shims, movable ejectors, etc. The scriber tooling cannot be reused, and the height of the shims needs to be adjusted each time according to the workpiece, which not only increases the labor intensity of the operator, but is also very unstable and has the risk of collapse. When the workpiece is clamped on the machine tool, the height of the positioning block needs to be adjusted according to the scriber reference, and the length and width of the workpiece need to be aligned in the form of fine-tuning. The labor intensity of the operator is high, the efficiency is low, and it is not suitable for mass production. Utility Model Content

For example, the term "one or more" as used herein may be used to describe any feature, structure, or characteristic in a singular sense, or may be used to describe a combination of features, structures, or characteristics in a plural sense, depending, at least in part, on the context. Similarly, terms such as "a," "an," or "the" may also be understood to convey singular usage or to convey plural usage, depending, at least in part, on the context.

[0099] It should be easily understood that “on,” “above,” and “over” in the present disclosure should be interpreted in the broadest manner, so that “on” not only means “directly on something,” but also includes the meaning of “on something” with intervening features or layers therebetween, and “above” or “over” not only includes the meaning of “above” or “over,” but also may include the meaning of “above” or “over something” with no intervening features or layers therebetween (i.e., directly on something).

[0100] In addition, spatially relative terms, such as "below," "below," "beneath," "above," "above," etc., may be used herein for ease of description to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. The device may have other orientations (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein may likewise be interpreted accordingly.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
