Adjusting and positioning device for front and rear inclination angle of scissors fixture in scissors grinding machine

Abstract

The invention discloses a front-back inclined angle adjusting and positioning device of a scissor clamp in a scissor grinding machine, comprising a main rack and the scissor clamp, wherein a front-back inclined angle fine tuning mechanism capable of adjusting a front-back inclined angle of the scissor clamp is arranged between the main rack and the scissor clamp. The front-back inclined angle adjusting and positioning device is structurally characterized in that a cantilever beam is fixedly arranged at one side of the main rack; the other end of a connecting shaft fixedly arranged on the cantilever beam passes through a connecting plate to be arranged at the upper part of a cross-shaped connecting block; a spring bracket is fixedly arranged at the outer side of the lower part of the cross-shaped connecting block; the spring bracket is internally provided with a compressed spring; one end of the compressed spring is connected with the spring bracket and the other end of the compressed spring is connected with the positioning block; the positioning block is fixedly connected with the connecting plate; the positioning block and the connecting plate are fixed and the connecting plate and the cantilever beam are fixed; the cantilever beam is provided with a supporting plate; and an inclined angle fine tuning screw passes through the supporting plate to tightly press the top surface at the left end of the cross-shaped connecting block. The front-back inclined angle adjusting and positioning device disclosed by the invention has the advantages that the working efficiency is improved, and the front-back inclined angle of the scissor clamp can be accurately adjusted and positioned.

Description

technical field [0001] The invention relates to a front and rear inclination angle adjusting and positioning device of a scissors fixture in a scissors sharpening machine. Background technique [0002] Scissors are assembled from two scissor blades. During the manufacturing process of the scissor blades, the scissor blades are usually fixed on the scissors fixture and then ground against the electric grinder; in order to reduce the In order to reduce the frictional force between the two scissors, it is necessary to process part of the surface of the scissors into a concave shape to reduce the contact area between the two scissors. The traditional operation method is to grind the scissors clamped in the scissors fixture against the grinding wheel manually. However, due to the limitation of the physical strength of the workers, it is difficult for the workers to keep the scissors fixture at the same processing angle for a long time. During the grinding process, the hands of w...

The traditional operation method is to grind the scissors clamped in the scissors fixture against the grinding wheel manually. However, due to the limitation of the physical strength of the workers, it is difficult for the workers to keep the scissors fixture at the same processing angle for a long time. During the grinding process, the worker's hand supporting the scissors fixture will inevitably shake, which not only makes it difficult to ensure the grinding quality, but also greatly reduces the work efficiency
