Compound tool for automobile piston processing

Abstract

The invention provides a compound tool for automobile piston processing. The compound tool is characterized by comprising a tool holder, a blade and a clamping mechanism, wherein the clamping mechanism comprises a clamping part; a bolt hole is formed in the clamping part, and the two ends of the clamping part are separately formed with a contact part and a clamping part; a blocking slot for blocking the blade in the axial direction and a threaded hole for fixing the clamping part are formed in the tool holder; a buckle strip which is matched with the blocking slot is arranged on the blade; theblade is arranged on the end part of the tool holder through the buckle strip so as to form blocking matching with the tool holder; the clamping part is connected on the tool holder through a bolt; and the clamping portion of the clamping part abuts against the blade, and the contact part between the clamping portion and the blade abuts against the end surface of the tool holder. The shape of thecutting edge of the tool is changed, so that simple turning is changed into efficient compound processing; moreover, the shape of the cutting edge of the blade is accurate, so that a product qualification rate is guaranteed; and a buckle structure is adopted on the bottom of the blade, and the blade is perfectly combined with a tool bar, so that the blade is guaranteed to not loosen in a processing process through a buckled combining way.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a composite cutting tool for processing automobile pistons. Background technique [0002] Automobile pistons are generally processed on CNC lathes by turning. The processing process is the end face of the workpiece and its internal and external R angles. The processing time of a workpiece is about 4 minutes. The production quantity of this type of product can reach tens of thousands. At present, traditional processing technologies are used at home and abroad, among which welding tools are widely used. The manufacture of welding tools is to weld the blade to the handle, and then manually grind the tool through the grinding wheel according to the shape of the workpiece. This kind of processing Although the method is efficient, there are various problems: 1. The manual sharpening of the grinding wheel will cause unsafe hidden dangers and cause environmental p...

Problems solved by technology

[0002] Automobile pistons are generally processed on CNC lathes by turning. The processing process is the end face of the workpiece and its internal and external R angles. The processing time of a workpiece is about 4 minutes. The production quantity of this type of product can reach tens of thousands. At present, traditional processing technologies are used at home and abroad, among which welding tools are widely used. The manufacture of welding tools is to weld the blade to the handle, and then manually grind the tool through the grinding wheel according to the shape of the workpiece. This kind of processing Although the method is efficient, there are various problems: 1. The manual sharpening of the grinding wheel will cause unsafe hidden dangers and cause environmental pollution; 2. The individual technical differences of each operator will affect the stability of the product size; 3. The tool wears out quickly, and the whole tool is scrapped and sold as scrap after wear, resulting in waste of resources; and this processing method has low production efficiency and high time cost, so how to shorten the processing time is the key to processing this product, changing the traditional The processing method is imperative to improve the processing efficiency of the product
