Description

Technical Field

[0001] The utility model belongs to the technical field of polishing rod processing equipment, in particular to a clamping device for polishing rod processing. Background Art

[0002] Polishing rods refer to rods made from metal discs or bars through spheroidizing annealing, drawing, straightening, chamfering, grinding and other steps. According to different materials, polishing rods can be divided into stainless steel polishing rods, copper alloy polishing rods, pure titanium polishing rods, titanium alloy polishing rods, etc. As an important type of metal material, polishing rods have been widely used in the manufacturing of equipment such as automobiles, home appliances, machine tools, engineering machinery, rail transportation, power tools, and medical equipment. The clamping device for polishing rod processing is a special fixture used to stably and accurately clamp the polishing rod during the grinding process to ensure processing quality and efficiency. The main purpose of the design of this device is to reduce vibration and offset during the grinding process, so as to obtain more accurate and smooth grinding results.

The seamless steel pipe can be clamped quickly through the set clamping mechanism, and the fixing effect between the upper arc clamping block and the lower arc clamping block is further improved through the set fixing mechanism, thereby increasing the stability when clamping the seamless steel pipe, and then improving the subsequent processing efficiency and processing quality. The structure is simple, easy to operate, the installation and disassembly speed of the seamless steel pipe is fast, and the practicality is higher. The distance between the two clamping mechanisms can be adjusted through the set moving mechanism, thereby facilitating the clamping of seamless steel pipes of different lengths, or clamping the seamless steel pipes at different positions, thereby improving the practicality and flexibility of the device.

[0013] First, in the present invention, after the polishing rod is fixed by the moving assembly, the third driving motor is started to control the first gear to rotate, and at the same time, the first gear drives the second gear to rotate, so that the connecting shaft rotates, the connecting shaft drives the rotating disk to rotate, and at the same time, the rotating disk drives the connecting block and the clamping block to rotate, so that the polishing rod rotates. By rotating the polishing rod, the grinding tool can be more easily approached and covered on the entire surface of the polishing rod, thereby reducing the distance and time of the grinding tool moving, making the processing operation more efficient and improving production efficiency;

[0014] Second, in the present invention, after the polishing rod is fixed by the moving assembly, the second driving motor is started to control the screw rod to rotate, and the screw rod and the moving seat are threadedly rotated, thereby controlling the moving seat to lift and lower. At the same time, during the lifting process, the sliding limit is performed with the outer side of the guide rod. At the same time, the moving seat drives the connecting block and the clamping block to lift and lower, so that the polishing rod is lifted and lowered. By lifting and lowering the polishing rod, the relative position between the polishing rod and the grinding tool can be accurately adjusted, which helps to ensure the stability and consistency of the processing process and avoid processing errors caused by improper position.

[0015] Third, in the present invention, the connecting block and the fixed block are combined, and the connecting block is inserted into the connecting groove. During the insertion process, pressure is applied to the inclined surface of the locking block, so that the locking block drives the movable plate to move. When the locking block moves to the locking groove, the reset spring resets, the movable plate rebounds, and the locking block pops out and is clamped and fixed with the locking groove to complete the installation of the clamping block. There is no need to spend too much time on the complicated installation and disassembly process, which greatly shortens the processing preparation time and improves the overall operating efficiency. In particular, in scenarios where the polishing rod diameter needs to be frequently changed or the clamping method needs to be adjusted, it helps to reduce the overall processing cost and improve production efficiency.
