Clamp for machining of resin dome cover flanged edge and with one-time clamping formation function and machining method for resin dome cover flanged edges

Abstract

A clamp for machining of a resin dome cover flanged edge and with a one-time clamping formation function is characterized in that a clamp framework is formed by a bottom plate, guide columns, a supporting air cylinder, a movable plate and a top plate; a vacuum fixing base is arranged on the movable plate; an inner cavity of the vacuum fixing base is matched with the outer surface of a dome cover; the upper end of the vacuum fixing base is provided with two layers of steps; the external diameter of the inner edge face of the first step is smaller than the dimension of the machined external diameter portion of the dome cover flanged edge; the external diameter of the inner edge face of the second step is equal to the dimension of the non-machined external diameter portion of the dome cover flanged edge; a stepped hole is formed in the center of the top plate; a dome cover positioning ring is embedded in the stepped hole of the top plate; a vacuum generating device is connected with a normally open one-way electromagnetic valve and a normally closed one-way negative-pressure electromagnetic, connected with the vacuum fixing base and used for conducting vacuumizing on the inner cavity of the vacuum fixing base; and the movable plate, the vacuum fixing base and the dome cover make vertical motion along the guide columns as the supporting air cylinder moves. According to the clamp, a vacuum clamping mode is adopted, all machining operations are completed through one time of clamping, the machining procedures are optimized dramatically, and the machining efficiency and product yield are improved.

Description

technical field [0001] The invention belongs to a processing jig for a resin optical dome cover, in particular to a jig for finely engraving, milling, surface milling, slot milling, hole milling and diameter milling on the flange side of an optical dome cover. [0002] Background technique: [0003] The resin optical dome cover of the present invention is a protective cover used for a dome camera, as figure 1 , 2 Optical dome shown with flanged sides. Since the resin optical dome cover is molded by injection molding, the flange side is its installation position, and the dome cover with the same diameter may be equipped with different models by different users, and the installation position is different, so it cannot be used universally. If the mold injection molding product is remade according to the size of each flange side, the development period is long and the cost is high; therefore, the flange side of the optical dome cover usually needs to be processed to meet the us...
