Device for clamping multiple workpieces

Abstract

The invention provides a device for clamping multiple workpieces. The device for clamping the multiple workpieces comprises a base plate, a fixing seat and clamping assemblies. The fixing seat and the clamping assemblies are arranged on the base plate; each clamping assembly comprises a slide rail, a first slide block, second slide blocks, a screw rod and a support; the fixing seat, the slide rails and the supports are fixed onto the base plate; each slide rail is arranged between the fixing seat and the corresponding support; each first slide block and the second slide blocks can be slidably arranged on each slide rail; each first slide block is connected with a plurality of second slide blocks; the second slide blocks are located between the first slide block and the fixing seat; a plurality of workpiece clamping stations are arranged on junction parts of a top wall and side walls of the fixing seat, and directly face the second slide blocks; each screw rod is erected on the corresponding support and is meshed with the corresponding support; and one end of each screw rod is connected with the corresponding first slide block. The device for clamping the multiple workpieces provided by the invention can be used for simultaneously clamping the processing workpieces stably on a large scale.

Description

technical field [0001] The invention relates to the field of machining, in particular to a clamping device for machining. Background technique [0002] In the field of mechanical processing, how to achieve fast and stable clamping of ultra-small parts that need to be processed in batches has always been an industry problem. The traditional vacuum fixture can clamp multiple workpieces at one time through vacuum adsorption, and the processing efficiency is high. However, since the adsorption force is directly proportional to the adsorption area, when the part is too small and the effective adsorption area is insufficient, the part is easy to loosen during processing, resulting in tool breakage, unstable processing size, poor surface quality and many other problems. Therefore, the vacuum adsorption method is not suitable for processing and fixing small-sized parts.

Problems solved by technology

However, since the adsorption force is directly proportional to the adsorption area, when the part is too small and the effective adsorption area is insufficient, the part is easy to loosen during processing, resulting in tool breakage, unstable processing size, poor surface quality and many other problems. Therefore, the vacuum adsorption method is not suitable for the processing and fixing of small-sized parts.

[0003] Due to its mechanical structure, the traditional vise can provide stable and reliable mechanical clamping force for parts clamping. However, due to structural limitations, there will be a certain fit gap between the movable jaw of the vise and the slide rail. When the movable jaw Under the condition of clamping force, the jaw will produce a small amount of inclination. At this time, if multiple parts of the same type are clamped at one time, usually only 2 to 3 parts can be effectively clamped, and the remaining parts will have clamping force. Insufficient or even completely suspended. In actual processing, in order to ensure reliable clamping, generally only 1 to 2 parts are clamped at a time, which seriously restricts the improvement of processing efficiency and cannot be applied to the processing of large-scale products.
