Adjustable and off-tracking-resistant double-faced sand belt polishing machine

Abstract

The invention discloses an adjustable and off-tracking-resistant double-faced sand belt polishing machine. The polishing machine comprises a machine base, and a rack above the machine base is divided into an upper layer and a lower layer; an upper layer driving component and a lower layer driving component are arranged on the upper layer and the lower layer respectively; the upper layer driving wheel comprises driven wheels, driven wheels and sand belts which are connected to the two ends of an upper layer drive respectively and adjusting brackets, wherein each adjusting bracket is arranged between the driving wheel and the corresponding driven wheel and used for adjusting the position of the corresponding driven wheel and the tension of the corresponding sand belt; the lower layer driving wheel comprises driven wheels, driven wheels and sand belts which are connected to the two ends of a lower layer drive respectively and adjusting brackets, wherein each adjusting bracket is arranged between the driving wheel and the corresponding driven wheel and used for adjusting the position of the corresponding driven wheel and the tension of the corresponding sand belt; By means of the adjustable and off-tracking-resistant double-faced sand belt polishing machine, tongs can be polished conveniently, rapidly and efficiently, the driven wheels can be effectively adjusted so that the sand belts can be adjusted, off-tracking or rocking is avoided, tension adjustment can be conducted as well, and meanwhile the tongs can be clamped and polished conveniently.

Description

technical field [0001] The invention belongs to the field of hardware tool processing machine tools, and relates to an adjustable anti-deviation double-sided abrasive belt polishing machine. Background technique [0002] Pliers are a commonly used hardware tool, which is a hand tool for clamping and fixing workpieces or twisting, bending and cutting metal wires. like figure 1 The pliers 90 shown is composed of two cross parts, the front end pliers head 901 is a bare working area, and the rear end pliers tail 902 is a force application area, which is used for working force. [0003] In the production process, the pliers are generally made of carbon structural steel, first forged and rolled into the shape of the pliers blank, and then processed by metal cutting such as grinding and polishing, and finally heat treated. After the initial assembly of the pliers is completed, manual polishing is currently mostly used for polishing. This not only reduces production efficiency, bu...

AI Technical Summary

Problems solved by technology

After the initial assembly of the pliers is completed, manual polishing is mostly used for polishing. This not only reduces production efficiency, but also easily leads to processing waste. Improper operation is more likely to cause injuries, and there are potential safety hazards.

[0004] The utility model patent ZL201020264186.9 applied by the applicant earlier, the application date is 2010-7-14, discloses a semi-automatic abrasive belt double-sided polishing machine for pliers grinding, but the disclosed technical solution has the following in actual processing and application Several major disadvantages: 1. In the process of processing, the abrasive belt is prone to shift and shake; 2. The tightness of the abrasive belt cannot be adjusted during the work of the abrasive belt; 3. The pliers need to be manually held during polishing, but the abrasive belt Attractive force easily draws the pliers into the device
