Problems solved by technology

With such a large scale of production, still using manual grinding is far from meeting the needs of high-quality, large-scale production
From the perspective of the manufacturing process of surgical blades, other processing procedures except edge grinding are relatively easy to realize mechanization and automatic processing, while the edge grinding of surgical blades is more complicated
This phenomenon has formed a bottleneck restricting the development of surgical blade manufacturing technology, seriously affecting the production efficiency of surgical blades

Embodiment

[0039] Embodiment: A kind of surgical blade edge automatic grinding machine

[0040] like figure 1 As shown, the automatic grinding machine includes a rotary tool holder mechanism (see figure 1 the left half of the), a grinding head mechanism (see figure 1 The right half of), a base 16 and the electrical control part.

[0041] like figure 1 and figure 2 As shown, the rotary knife seat mechanism has a knife seat body 4 for positioning the surgical blade 1, and the knife seat body 4 is provided with a pressing plate 5 for pressing the surgical blade 1, and the pressing plate 5 and the knife seat body 4 are arranged vertically. The sliding connection is formed by the guide pin 11 in the direction of the straight Z axis. A pressing device is installed on the tool holder body 4, the pressing device is a pressing cylinder 6, the piston rod of the pressing cylinder 6 is connected with the pressing plate 5 as the action end of the pressing device, under the action of the pressing ...

Abstract

The invention relates to an automatic grinding machine for a cutting edge of a surgical knife blade, which is provided with a rotation knife holder mechanism and a grinding head mechanism, wherein the rotation knife holder mechanism is used for clamping the knife blade; the grinding head mechanism is used for grinding the cutting edge; the two mechanisms are effectively combined in space; after the knife blade is clamped, a grinding wheel is driven by a grinding head motor to rotate at high speed; the grinding wheel is pushed to the position of the cutting edge by a first linear driving mechanism to carry out grinding; the grinding wheel is driven by a second linear driving mechanism to feed grinding quantity and compensate the abrasion loss of the grinding wheel relative to the knife blade; the grinding wheel is driven by a third linear driving mechanism to carry out linear cutting edge section grinding relative to the knife blade; and the knife blade is driven by a rotation control motor to carry out circular arc cutting edge section grinding relative to the grinding wheel. The automatic grinding machine for the cutting edge of the surgical knife blade is capable of breaking through the limitation of traditional manual grinding, carrying out automatic grinding on the surgical knife blade with a linear circular arc cutting edge, a circular arc cutting edge and a linear cutting edge, greatly reducing the labor strength and improving the production efficiency and the processing quality, and has very high practical value.

Description

technical field [0001] The invention relates to automatic processing equipment for medical surgical blades, in particular to an automatic grinding machine for cutting edges of surgical blades. Background technique [0002] China has produced surgical blades for 50 years. For a long time, the production of surgical blades has always been a labor-intensive process, especially the edge grinding of surgical blades has been done by hand for 50 years. After the reform and opening up, aseptically packaged surgical blades produced in China entered the international market for the first time. At present, the surgical blades produced in China are not only sold domestically, but also exported in large quantities. According to statistics, the total annual sales volume of surgical blades in the world is between 800 million and 1 billion pieces, while only one largest manufacturer of surgical blades in China has 200 million pieces. With such a large production scale, still using manual...
