Description
Technical Field
The utility model relates to the technical field of cylinder casting, in particular to a cylinder positioning surface machining clamp.
Background
In the prior art, when preparing the engine cylinder body, the cylinder body needs to be positioned by adopting a cylinder body clamp for positioning, so that the cylinder body is convenient to repair and carry. As in the patent publication CN205834784U, a clamp for an engine block is disclosed in which the block can be fixed.
However, as the requirements on the accuracy of the engine cylinder body are higher and higher, and the requirements on the quick positioning of the clamp on the cylinder body are also higher and higher, the requirements on the positioning accuracy and the quick positioning are often contradictory, and generally the requirements on the positioning accuracy are higher, the longer the detection time is required during positioning, which is unfavorable for improving the production efficiency.
Therefore, a new solution is needed to solve the above-mentioned problems.
Disclosure of Invention
In order to solve the problems generated by the prior art, the utility model provides a cylinder body positioning surface machining clamp which can realize quick positioning under the condition of meeting positioning precision.
In order to achieve the above purpose, the cylinder positioning surface processing clamp can adopt the following technical scheme:
a cylinder positioning surface machining clamp comprises a base, a supporting plate and a supporting column, wherein the supporting plate extends upwards vertically from the upper surface of the base, and the supporting column extends from the upper surface of the supporting plate parallel to the base; the front end of the support column is a threaded column, and a self-positioning nut and a locking nut positioned at the outer side of the self-positioning nut are installed on the threaded column; the self-positioning nut comprises a threaded hole, positioning surfaces extending from the threaded hole to two sides symmetrically are inclined planes, and when the cylinder body is installed, the two positioning surfaces are respectively and symmetrically abutted against two sides of the opening of the cylinder body cylinder barrel.
Further, when the cylinder is installed, the two locating faces face inwards and the lock nut abuts against the outer surface of the self-locating nut.
Further, the support columns include at least two support columns, and the at least two support columns extend in parallel.
Further, the support column is detachably arranged on the support plate.
Further, the backup pad detachably installs on the base.
Further, the two support columns are respectively inserted into two outermost cylinders in a row of cylinders of the cylinder body.
The beneficial effects are that: compared with the prior art, in the technical scheme provided by the utility model, the cylinder barrel of the cylinder body is inserted through the support column, and the cylinder barrel is directly positioned in a manner that two inclined positioning surfaces of the self-positioning nut are contacted with the cylinder barrel, and because the two positioning surfaces are symmetrical, the positioning is completed when the self-positioning nut is screwed down, and the cylinder body can be rapidly positioned on the clamp while the positioning precision requirement is met.

Detailed Description
The present utility model is further illustrated in the accompanying drawings and detailed description which are to be construed as exemplary only and not limiting the scope of the utility model, since modifications to the utility model in the art will fall within the scope of the utility model which is defined by the appended claims after reading the utility model.
Referring to fig. 1, the utility model discloses a cylinder positioning surface machining fixture, which comprises a base 1, a supporting plate 2 extending vertically upwards from the upper surface of the base 1, and two supporting columns 3 extending in parallel from the upper surface of the supporting plate 2 parallel to the upper surface of the base. The front end of the support column 3 is a threaded column 31. The screw column 31 is provided with a self-positioning nut 4 and a locking nut 5 positioned outside the self-positioning nut 4. As shown in fig. 3 and 4, the self-positioning nut 4 includes a threaded hole 41, and positioning surfaces 42 extending from the threaded hole 41 to both sides symmetrically in inclined planes. The support column 3 is detachably mounted on the support plate 2, and the support plate 2 is detachably mounted on the base 1.
As shown in fig. 2, 5 and 6, when the cylinder 6 is mounted, the two support columns 3 are inserted into the outermost two cylinders of the cylinder 6 in the row of cylinders 61, respectively. In this embodiment, four cylinder blocks, that is, four cylinders 61 arranged side by side are mounted on the jig. The two locating surfaces 42 of the self-locating nut 4 face inwards, and the two locating surfaces 42 are respectively and symmetrically abutted against the two sides of the cylinder barrel opening. The lock nut 5 abuts against the outer surface of the self-positioning nut 4.
As shown in fig. 6, when the cylinder is mounted on the jig, the support column 2 is coaxial with the cylinder 61 of the cylinder, and is engaged with two inclined positioning surfaces of the self-positioning nut 4 through both side edges 62 of the cylinder outlet. When the self-positioning nut 4 is screwed and locked, the self-positioning nut 4 and the side edge 62 of the cylinder barrel are tightly attached together, that is, the inclined positioning surface 42 of the self-positioning nut 4 and the circular edge of the cylinder barrel of the cylinder body are positioned in a line contact manner, in this case, the self-positioning nut 4 and the cylinder barrel form two concentric circles on one axis to limit in all directions, so that the expected positioning precision is also achieved when the self-positioning nut 4 is locked.
