A Workpiece Clamping Mechanism for Common Small Machine Tools

Abstract

The invention discloses a workpiece clamping mechanism of a common small machine tool. The workpiece clamping mechanism comprises a supporting baseplate and workbench, wherein a fastening assembly isfixedly mounted on the lower surface of the supporting baseplate; a bearing mounting groove is formed in the upper surface of the supporting baseplate; and a mobile bearing is arranged inside the corresponding bearing mounting groove in the upper surface of the supporting baseplate in an embedding manner. The workpiece clamping mechanism disclosed by the invention has the beneficial effects that through the design of the fastening assembly, the workpiece clamping mechanism can be relatively quickly mounted and dismounted, the working difficulty can be lowered, the convenience can be brought toworking personnel, and the practicability and the applicability of the workpiece clamping mechanism can be improved; through the design of an adsorbing assembly, not only can debris generated from the processing be subjected to adsorbing treatment and the clutter caused by the scattering of the debris be avoided, but also internal processed workpieces can be protected; and through the design of afirst station and a second station, the rotary operation can be performed, the workpiece on the other station can be conveniently dismounted and mounted when the workpiece on one station is processed, the waiting time can be avoided, and the working efficiency can be improved.

Description

Technical field [0001] The invention relates to the field of workpiece clamping mechanisms of machine tools, in particular to a workpiece clamping mechanism of ordinary small-scale machine tools. Background technique [0002] Machine tools refer to machines for manufacturing machines, also known as machine tools or machine tools. Traditionally referred to as machine tools, they are generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many methods for processing mechanical parts in modern machine manufacturing: except for cutting. , As well as casting, forging, welding, stamping, extrusion, etc. During the processing of the machine tool, a clamping mechanism needs to be used to clamp the processed workpiece to complete the production of the processed workpiece. [0003] The Chinese patent discloses a clamping mechanism (authorized announcement number CN108621052A). The patented technology states that by providing a movabl...

Problems solved by technology

[0003] The Chinese patent discloses a clamping mechanism (authorized notification number CN108621052A). This patent technology is provided with a movable clamping shaft above the base, so that the object to be clamped can be lifted during use, and combined with the setting of the positioning block It can realize the fixing of objects, and has the effect of simpler structure and convenient use; the present invention has simple structure, convenient manufacture, large range of clamping and reliable force application, good self-locking performance, and good clamping effect. In addition, the Chinese patent discloses a clamping Tightening mechanism (authorized notification number CN109129238A), the patented technology shows that through the two-stage jaw structure, it can ensure the rigid fixation of the rear end clamp and the flexible contact of the front end clamp during the clamping process, but the current clamping device is used In the process, there are still many deficiencies. There are no multiple stations, and multiple workpieces cannot be clamped and fixed at the same time, which prolongs the working waiting time. The clamping mechanism is relatively cumbersome to install and increases the work The workload of the personnel, and the debris generated during processing is more, it is not convenient to deal with it, and it is easy to cause messy phenomenon
