Machining tool and machining process of special-shaped stainless steel products

Abstract

The invention discloses a machining tool of special-shaped stainless steel products. A first product clamping mechanism and a second product clamping mechanism each comprise a fixing block, positioning blocks, pressing blocks and compressing bolts. As for each product clamping mechanism, a cushion block is fixed on the fixing block; the positioning blocks are fixed on the cushion block; a threadedhole is formed in each positioning block; each pressing block is placed on the top end face of a sleeve of the corresponding special-shaped stainless steel product after the top end of each positioning block is sleeved with the sleeve of the special-shaped stainless steel product; each compressing bolt is fixedly in threaded connection with the corresponding threaded hole after penetrating through the corresponding pressing block and the sleeve of the corresponding special-shaped stainless steel product; after being attached to the top surface of the corresponding pressing block, the head ofeach compressing bolt presses and fixes the sleeve of the corresponding special-shaped stainless steel product; and a positioning structure for positioning an inclined rod of each special-shaped stainless steel product is further arranged on the cushion block. By means of the machining tool, a workpiece can be clamped quickly and conveniently, finish machining is convenient, and the precision of products after finish machining is further improved.

Description

technical field [0001] The invention relates to the technical field of mechanical clamping, in particular to a processing tool for special-shaped stainless steel products. Background technique [0002] With the increase of the middle class in China and the upgrading of consumption concepts, the number of people buying high-end cars is increasing; at present, for the high-end car engine exhaust sound valve, as an important part connecting the high-temperature end of the engine and the exhaust pipe, its processing accuracy (The position of each hole of the engine exhaust valve is guaranteed to be within 0.15mm; usually the customer's requirement is within 0.5mm; each angle can be guaranteed within + / -0.25 degrees; the contour is guaranteed to be within 1mm) and the difficulty of saving the cost of the car The control of the sound wave is very important; therefore, the product needs to be finished after casting, and its product consists of a short sleeve body, a diagonal rod lo...

[0002] With the increase of the middle class in China and the upgrading of consumption concepts, the number of people buying high-end cars is increasing; at present, for the high-end car engine exhaust sound valve, as an important part connecting the high-temperature end of the engine and the exhaust pipe, its processing accuracy (The position of each hole of the engine exhaust valve is guaranteed to be within 0.15mm; usually the customer's requirement is within 0.5mm; each angle can be guaranteed within + / -0.25 degrees; the contour is guaranteed to be within 1mm) and the difficulty of saving the cost of the car The control of the sound wave is very important; therefore, the product needs to be finished after casting, and its product consists of a short sleeve body, a diagonal rod located outside the sleeve body, a flat plate located on the side of the diagonal rod, and a flat protrusion on the flat plate Composed of two short cylinders, this product is rather weird and complicated. During processing, it is difficult to carry out stable clamping for the current clamping tools (bench vise, three-jaw chuck and four-jaw chuck, etc.), even if It is also relatively difficult to process after clamping, which reduces the efficiency of processing and production, and it is easy to scrap products during product processing, and the precision of finished products is relatively low.
