Abstract

The utility model relates to a novel planing tool for woodworking, which is a cutting tool of wood plane surface processing machinery. A rotary planing tool is used for processing the wood plane surface. Thus the resistance is small; the noise is small; the power of a motor is small; the electricity is saved; the cost is reduced; the operation is safe. The planing tool is composed of a planing tool rotating shaft, a planing tool seat and a planing tool. The planing tool rotating shaft and the planing tool seat are connected into a whole. The planing tool seat is provided with a groove or a cross section for arranging the planing tool. A press plate is arranged in the groove or on the cross section. The press plate is provided with a threaded hole. The planing tool is arranged in the groove or is placed on the cross section, and is fastened by screws and the press plate. The groove or the cross section are twisted in a helical shape. The planing tool and the press plate are twisted correspondingly to match with the groove or the cross section.

Description

Planing tool for woodworking

Novel carpenter's plane cutter is a kind of cutting tool of timber plane surface processing equipment.

The rotary cutting tool of existing timber plane surface processing equipment, the knife-blade that is contained on the rotating shaft is a flat shape, during process wood, when timber width during greater than the length of cutter, the charging simultaneously of the whole edge of a knife, resistance is bigger, need be than heavy-duty motor, noise is also big, big energy-consuming.

The purpose of this utility model is: a kind of design of novel carpenter's plane cutter is provided, and when utilizing this planing cutter tools process wood plane surface, resistance is little, and noise is little, and used power of motor is little, favourable economize on electricity and reducing cost.

Embodiment of the present utility model is: novel carpenter's plane cutter is made of planing tool rotating shaft, adz block and planing tool, planing tool rotating shaft and adz block are connected as a single entity, the groove or the cross section that have the dress planing tool to use on the adz block, planing tool be placed in the groove or the cross section on, fastening with screw or screw and pressing plate, screw is all arranged on the pressing plate or on pressing plate, planing tool and the adz block, the shape distortion in the shape of a spiral of groove on the adz block or cross section, the shape of planing tool and pressing plate is also done corresponding distortion, is complementary with torsive groove or cross section.2～4 torsive grooves or cross section are arranged on the adz block, in each groove or the cross section planing tool that is complementary with it is housed all, the planing tool mouth is circular arc, and is consistent on the circular arc of planing tool mouth and the adz block.

The utility model can be made into the product that is out of different specification size, be applicable to multiple carpenter's plane machineries such as planer, thicknesser, electric hand planer, because whole circular arc planing tool mouth does not contact with timber simultaneously, but charging successively successively, therefore, have that edge of a knife charging resistance is little, noise is little, used power of motor is little, power saving and low cost and other advantages, also help operating personnel's safety.

Below in conjunction with drawings and Examples the utility model is further specified:

Among the figure: 1, planing tool rotating shaft, 2, adz block, 3, the trapezoidal groove mouth, 4, trapezoidal groove bottom line, 5, trapezoidal groove, 6, the planing tool mouth, 7, screw, 8, screw, 9, screw, 10, planing tool mouth, 11, rotating shaft, 12 adz blocks, 13, rotating shaft, 14, adz block, 15, screw, 16, planing tool mouth, 17, screw, 18, screw.

Example 1:

Novel carpenter's plane cutter (is seen Fig. 1, Fig. 2) by planing tool rotating shaft 1, adz block 2 and planing tool constitute, planing tool rotating shaft 1 is processed into parts with adz block 2, or planing tool rotating shaft 1 packed into connect as one with key in the circle center hole of adz block 2, the trapezoidal groove 5 that the helical form button song used of dress planing tool is arranged on the adz block, the radial section of groove 5 is trapezoidal shape, be helically twisted shape axially, be placed with the helical form that is complementary with it in the torsive trapezoidal groove 5 and twist trapezoidal pressing plate less than groove, screw is arranged on the pressing plate, planing tool is packed in the trapezoidal groove, be screwed in the screw on the pressing plate with screw, screw one end that is screwed into screw passes the bottom that pressing plate withstands trapezoidal groove, moves on the trapezoidal pressing plate, is close to the trapezoidal groove two sides and closes, clamp planing tool, planing tool is fixed.Planing tool (seeing Fig. 3, Fig. 4, Fig. 5) is complementary with torsive trapezoidal groove and torsive trapezoidal pressing plate, and planing tool is helically twisted to be to make successively the planing tool mouth charging angle unanimity of charging successively.2～4 torsive trapezoidal grooves are arranged on the adz block, the planing tool that is complementary with it is housed in each groove.Planing tool mouth 6 is the circular arc (see figure 3), and the circular arc of planing tool mouth is consistent with adz block.

Embodiment 2:

With the difference of embodiment 1 be 2 helically twisted cross section (see figure 6)s that have the dress planing tool to use on the adz block 12, the planing tool (see figure 7) is also done corresponding distortion, be complementary with helically twisted cross section, fixedly connected with the screw 7 on the adz block 12 by the screw on the planing tool 8 with screw 9, planing tool mouth 10 is circular arc, and is consistent with adz block.

Embodiment 3: with the difference of embodiment 2 be the helically twisted cross section (see figure 8) that four dress planing tools that the dress planing tool uses are arranged on the adz block 14, planing tool is also done corresponding distortion, be complementary with coil cross section, fixedly connected with the screw 15 on the adz block 14 by the screw on the planing tool 18 with screw 17, planing tool mouth 16 is circular arc, with consistent on the adz block.
