Batch machining method for fan-shaped parts

Technical Field

The invention relates to the technical field of part processing, in particular to a sector part batch processing method.

Background

As shown in figure 2, the part 1 is a sector part, and bosses 2 with a certain height are required to be formed on two sides of the part 1, and the special shape brings difficulty to the clamping and fixing of the part. As shown in figure 3, in the prior art, one side of the sector part 1 is supported by the wedge 3 ' to ensure the level of the processing surface of the other side, and then the part is limited in a surrounding mode by the left limiting block 4 ', the right limiting block 4 ' and the upper limiting block 4 ', so that the clamping of a single part is completed, and for the part with radian difference, the wedge 3 ' matched with the inclination needs to be selected, so that the operation is inconvenient, the processing efficiency is low, and the requirement of batch production cannot be met.

Disclosure of Invention

Based on the above problems, the present invention aims to provide a method for processing sector parts in batches, which facilitates clamping and processing of the sector parts, improves processing efficiency, and ensures part quality.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a fan-shaped part batch processing method, wherein the both sides shaping of part has the boss, and the height of boss is less than the height of part, includes the step: cutting the blank by a wire to form a sector shape of the part, and forming convex edges with the same height as the part on two side surfaces of the part; vertically clamping a plurality of parts on a plane grinding machine through an auxiliary jig, and enabling one side surface of each part to be flush; the convex ribs of all parts are processed into bosses with consistent height in a side grinding mode.

Especially, supplementary tool includes locating piece and dog, is provided with smooth side reference surface on the locating piece, sets up the constant head tank that a plurality of is used for placing bead or boss on the side reference surface, and when bead or the boss of each part side put into the constant head tank, the side that corresponds pastes with side reference surface and leans on, and the dog is located one side of side reference surface in parallel, and presses in the another side of part to press each part tightly.

In particular, the width and depth of the locating groove are greater than the cross-sectional dimension of the boss or pimple of the part.

In particular, the height of the positioning block is smaller than the height of the boss.

Particularly, the positioning block and the stop block are processed by waste blocks or defective products.

In conclusion, the batch machining method for the fan-shaped parts has the advantages that the fan-shaped parts are formed by combining wire cutting and side grinding aiming at parts with special shapes, the machining mode is changed, and the parts are reliably clamped in batches through the auxiliary jig, so that the machining precision is ensured, and the machining efficiency and the yield are improved.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar parts throughout or parts having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning a fixed connection, a removable connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediary, a connection between two elements, or an interaction between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the description of the present invention, unless otherwise expressly specified or limited, the first feature "on" or "under" the second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature being in contact not directly but with another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Referring to fig. 1, the preferred embodiment provides a method for batch processing of sector-shaped parts, and for a part 1 in fig. 2, bosses 2 are formed on two sides of the part 1, and the height of the bosses 2 is smaller than that of the part 1, specifically including the following steps:

s1: the blank is cut by a wire to form the sector shape of the part 1, and convex edges with the same height as the part 1 are formed on the two side surfaces of the part 1. The wire cutting can meet the molding requirement of the special-shaped curved surface, the allowance of the special boss 2 which needs to be removed in size is large, and the special-shaped curved surface can be processed by adopting a plane grinding mode according to the size requirement.

S2: a plurality of parts 1 are vertically clamped on a plane grinding machine through an auxiliary jig, and one side surface of each part 1 is flush.

The auxiliary fixture of here includes locating piece 3 and dog 4, be provided with smooth side reference surface on the locating piece 3, set up the constant head tank 5 that a plurality of is used for placing bead or boss 2 on the side reference surface, when bead or boss 2 of 1 side of each part are put into constant head tank 5, the side that corresponds pastes with side reference surface and leans on, dog 4 is located one side of side reference surface in parallel, and press in the another side of part 1, thereby press tightly each part 1, the invisible arc angle of this clamping mode.

In particular, the width and depth of the positioning groove 5 are larger than the cross-sectional dimension of the boss 2 or convex rib of the part 1, and the height of the positioning block 3 is smaller than the height of the boss 2. In addition, the positioning block 3 and the stop block 4 can be processed by waste blocks or defective products, so that the jig cost is reduced.

S3: the convex edges of all the parts 1 are machined into bosses 2 with the same height in a side grinding mode, and batch high-efficiency machining is completed.

Through practical use, taking 6 parts to be processed as an example, compared with clamping and processing of a single part in the past, the efficiency is improved by nearly 3 times, and the improvement effect is obvious.

In conclusion, the batch machining method for the fan-shaped parts aims at the parts with special shapes, the parts are formed by combining wire cutting and plane grinding, and the parts can be reliably clamped in batches through the auxiliary jig, so that the machining precision is guaranteed, and the machining efficiency and the yield are improved.
