Description

Clamping tool for woodworking blade

Technical Field

The utility model relates to the technical field of machining, concretely relates to carpenter's blade clamping frock.

Background

Woodworking tools are tools that machine wood into a desired shape and size by cutting methods. Woodworking tools are used both manually and mechanically, and machine tools are used in both batch and mass production. Woodworking tools for machines are classified into 5 types of saws, blades, milling cutters, drills, and mortise machining tools.

The woodworking blade is quadrilateral structure, the inside is provided with the through-hole, its four sides form the cutting edge, generally grind through the instrument and go up grinding, the traditional grinding mode of woodworking blade is ground at ordinary instrument, do the frock, it compresses tightly to adorn the blade on the frock, then manual layer board feeds the grinding, grind one side and take off and trade a face and grind again, it is repeated 4 times, just grind 4 faces of blade, the problem that exists like this is clamping many times, the error of clamping increases, the symmetry, the size all is difficult to guarantee.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that current carpenter's blade grinding carries out a lot of clamping through the frock, and the error of clamping increases, and the symmetry, the size all is difficult to guarantee, and its aim at provides a carpenter's blade clamping frock, and this frock adopts disposable grinding to the symmetry and the size of blade are guaranteed in the centering of hole, reduce the clamping error.

The utility model discloses a following technical scheme realizes: carpenter's blade clamping frock, including blade holder, the blade clamp base that sets gradually, press from both sides tight base, dividing head and cavity revolving cylinder, be provided with the pull rod in the dividing head, and the pull rod passes simultaneously and presss from both sides tight base, dividing head and cavity revolving cylinder, the one end of pull rod is arranged in the blade clamp base, cavity revolving cylinder can drive the pull rod and remove along self axis, be provided with blade pull rod and clamping jaw in the blade clamp base, can be fixed with the one end that the pull rod is arranged in the blade clamp base when the clamping jaw closes, the one end of blade pull rod is passed the blade holder and is arranged in the blade holder outside, the other end of blade pull rod can be rather than fixed when the clamping jaw scope is arranged in and the clamping jaw closes, the blade pull rod can remove in the blade holder along self axis, install servo. Carpenter's blade is quadrangle structure, the cutting edge all forms along its four borders abrasive machining, quadrangle center department is provided with the mounted position that the through-hole used as the blade, contact surface increases when making the installation, the through-hole generally all can design for the circular cone poroid, present grinding mode is on ordinary instrument grinds, utilize current frock, it compresses tightly on the frock to adorn the blade, expose one of them face as the machined surface, then manual layer board feeds the grinding, open the frock after having ground one face and take out the blade and rotate 90 and trade a face and grind again, need repeat 4 times, just grind 4 faces of blade, the problem that exists like this is many times clamping, low efficiency, the error of clamping increases, the symmetry and the size of blade all are difficult to guarantee. In order to solve the problems, the scheme designs a clamping tool which utilizes a blade seat, a blade clamping base, a dividing head and a hollow rotary cylinder which are arranged in sequence, a pull rod is arranged in the dividing head and simultaneously passes through the clamping base, the dividing head and the hollow rotary cylinder, one end of the pull rod is positioned in the blade clamping base and can be driven to move along the axis of the pull rod through the hollow rotary cylinder so as to press a blade, a blade pull rod and a clamping jaw are arranged in the blade clamping base and can be fixed with one end of the pull rod positioned in the blade clamping base when the clamping jaw is closed, one end of the blade pull rod passes through the blade seat and is positioned outside the blade seat, the other end of the blade pull rod is positioned in the range of the clamping jaw and can be fixed with the clamping jaw when the clamping jaw is closed, the blade pull rod can move in the blade seat along the axis of the blade, and the, the servo motor arranged on the dividing head is used for controlling the selection angle when the four surfaces of the blade are ground, the blade does not need to be taken out from the tool for repeated clamping, the tool is only required to be rotated, the clamping times are reduced, the grinding efficiency is improved, and meanwhile, the error is also reduced, so that the symmetry and the size of the blade are ensured.
