Description

Planer

This creation relates to the cutting field of woodworking, especially a planer, which is suitable for chamfering.

A known planer is found in Taiwan Patent No. M307510, which consists of a guide seat, a blade, and a pressing piece. Wherein, the guide base extends downward with two guide portions, so that a guide groove is formed at the bottom of the guide base. The bottom end of each guide portion forms an inclined guide surface toward the inner side, and the inclined guide surfaces of the two guide portions form a right angle. The top surface of the guide seat forms an inclined surface, and a transverse slot hole of the inclined surface is connected to the guide groove at the bottom of the guide seat. The pressing piece is combined with the inclined surface of the guide seat, and the blade is fixed on the inclined surface, so that the cutting edge passes through the transverse slot hole to expose the guide groove.

When combined, the two fixing elements pass through the pressing piece like screws and are locked into the guide base. When disassembling, the two fixing elements leave the guide seat, and the pressing piece and the blade are taken out. Therefore, the assembly and maintenance of the planer is quite time-consuming. Secondly, the fixing element does not lock the guide seat, the pressing piece will not press the blade, so that the blade may fall off when sliding relative to the guide seat. Furthermore, the distance between the two guide portions is relatively far, and during chamfering cutting, only a single inclined guide surface is often able to contact the side edge of the wooden object, so the movement of the planer is unstable.

In order to improve the above-mentioned shortcomings, the planer of Taiwan Patent No. M367796 has an additional positioning stopper for raising a pressing piece, and the two are passed through by a stud. One end of the stud is fixed on the guide seat, and the other end is locked with a wing nut, so that the pressing plate can press the blade, so as to position the blocking plate against the back of the blade and fix the position of the blade in the guide seat, so that the blade is inlaid by the guide seat. A strong magnet holds it.

However, the guide base is erected with two positioning posts, each of which is inserted into a positioning hole of the positioning block to prevent the positioning block from rotating around the stud. The number of components to be assembled increases, but it drags down the assemblers and relatively prolongs the installation time.

In view of this, the creator of this case provides a new planer, the main purpose is to: adopt the structural design of the chute, relatively widen the space required for blade assembly, and omit the use of pressing components in the prior art, which not only saves the production cost, but also shortens the assembly. aging.

In order to achieve the above purpose, the planing knife of this creation includes: a blade has a blade edge and a blade back, from the blade edge to the blade back is regarded as the width of the blade; a rectangular body has six surfaces, which are defined as a top surface and a bottom surface. , two end faces and two side faces, the bottom surface of the body forms an angle groove, the angle groove is connected to the two end faces; an assembly groove is formed on the body and communicates with the angle groove, and its width is smaller than the width of the blade, the assembly groove The groove is connected to the two sides and is staggered in the corner groove; and, a chute is formed at the corner of the assembly groove, the groove receives the cutting edge, and guides the blade to lie in and out of the assembly groove to complete the feeding or retracting Operation.

In this way, the planer of the present invention uses the chute to widen the bottom space of the assembly groove, completes the installation of the blade, and omits the use of pressing components in the prior art, which not only saves the production cost, but also shortens the assembly time.

The main body 20 has an assembly groove 30 , the assembly groove 30 staggers the narrow grooves 26 (or the corner grooves 25 , see FIG. 2 ) and is connected to the two side surfaces 24 , so the two ends of the assembly groove 30 are open. A bottom surface that defines the assembly groove 30 is a blade surface 31 , which maintains a predetermined depth with the top surface 21 of the main body 20 , and a cutting angle 14 is sandwiched between the blade surface 31 and the bottom surface 22 (see FIG. 5 ). A transverse hole 34 is formed in the blade setting surface 31, and the transverse hole 34 is connected to the corner groove 25 via the narrow groove 26 (see Fig. 5).

Secondly, the two wall surfaces of the assembly groove 30 stand on both sides of the blade setting surface 31 , and each wall surface is connected to the two side surfaces 24 of the main body 20 . The distance between these walls is approximately equal to the width of the blade face 31 , and the width of the blade face 31 is smaller than the width of the blade 11 . One of the two wall surfaces is connected from the top surface 21 of the main body 20 to one side of the blade setting surface 31 along an obtuse angle (see FIG. 5 ). When looking down on the body 20 (see FIG. 2 ), the wall surface is exposed and regarded as the exposed surface 32 . The exposed surface 32 forms an obtuse angle 321 with the upper side 24 in FIG. 2 and an acute angle 322 with the lower side 24 in FIG. 2 . Preferably, the acute angle 322 and the obtuse angle 321 are complementary angles to keep the exposed surface 32 in an inclined state. A longitudinal hole 35 is formed in the exposed surface 32, which is connected to the corner groove 25 via the narrow groove 26, the longitudinal hole 35 is connected to the transverse hole 34 and is located in the part of the exposed surface 32 adjacent to the blade surface 31 (see Fig. 5).

The other wall surface of the assembly groove 30 is connected from the top surface 21 of the main body 20 to the other side of the blade setting surface 31 at an acute angle (see FIG. 5 ). When looking down on the main body 20 (see Figure 2), only the edge of the wall can be seen, and the wall can only be seen from a side view (Figure 5 or 6), so it is defined as the hidden surface 33. The hidden surface 33 is substantially parallel to the exposed surface 32 .

As shown in Figures 1, 2, and 5, the assembly groove 30 also has a sliding groove 36, which is formed at the junction of the blade setting surface 31 and the exposed surface 32, and is connected to the vertical hole 35 through the horizontal hole 34. , so that the distance from the chute 36 to the hidden surface 33 is greater than the width of the blade 11 . The chute 36 has an open end and a closed end. The open end allows the chute 36 to connect to the lower side 24 in FIG. 2 as an entrance 37. The closed end prevents the chute 36 from reaching the upper side 24 in FIG. 2. blocking portion 38 .

The assembly groove 30 also has a knife relief portion 40 , the knife relief portion 40 is a notch, and the notch is opposite to the entrance and exit 37 of the chute 36 . Specifically, the escape part 40 and the inlet and outlet 37 are at the same end of the assembly groove 30 , and the escape part 40 is composed of a longitudinal wall 41 and a transverse wall 42 connected, so that the escape part 40 is just at the body 20 , the position The gathering place of the blade face 31 and the hidden face 33 .

In addition, the planer also has a set of magnets 50 . The magnet 50 is a permanent magnet. The permanent magnet is embedded in the body 20 and is flush with the blade setting surface 31 .

During assembly, the blade 12 enters the chute 36 through the inlet and outlet 37 , and the entire blade 11 lies on the cutting surface 31 of the assembly groove 30 , with the blade back 13 facing the knife retracting portion 40 . The blade 11 receives a thrust force to advance uniformly on the blade setting face 31 , so that the blade tip passes through the horizontal hole 34 and the vertical hole 35 .

As shown in FIG. 3 , the blocking portion 38 is pressed against the cutting edge, so that the blade 11 stays at the predetermined position of the cutting surface 31 . Part of the cutting edge 12 is shown in the vertical hole 35 when viewed from above.

In FIGS. 4 and 5 , the blade back 13 contacts the hidden surface 33 , and the hidden surface 33 prevents the blade 11 from being lifted relative to the opposing blade surface 31 , so that the retracting part 40 is exposed at a corner of the main body 20 . The set of magnets 50 attracts the blade 11 lying on the blade surface 31 , the blade 11 maintains the same cutting angle 14 as the bottom surface 22 of the main body 20 , and the narrow groove 26 (or the corner groove 25 ) is exposed in the middle of the blade 12 .

The cutting angle 14, referred to here, is between 45510 and the blade 11 is suitable for cutting a chamfer in medium-hard wood. If the cutting angle 14 is between 304010 and 304010, the blade 11 is suitable for chamfering in cork.

As shown in Figs. 4 and 6, a pulling force counteracting magnet 50 exerts the magnetic attraction force on the blade 11, the hidden surface 33 restricts the movement of the blade 12 in the chute 36, and the blade 11 evenly retreats on the blade setting surface 31 until the back of the blade The blunt end of 13 goes beyond the vertical wall 41 until it is positioned above the horizontal wall 42 . By clamping the blunt end of the blade back 13 , the blade 11 can be smoothly pulled out from the assembling groove 30 . Repeat the aforementioned actions to easily complete the tool change operation.

In this embodiment, the structure of the planer 10 is quite simple, and the body 20 is formed with staggered corner grooves 25 and assembling grooves 30 . The chute 36 guides the blade 11 to go into and out of the assembly groove 30 lying flat to complete the feeding or retracting operation of the planer 10 . By adopting the design of the chute 36 , the bottom space of the assembly groove 30 is relatively widened, and the installation blade 11 becomes the planer blade 10 . Therefore, the present embodiment omits the use of the pressing components of the prior art, which not only saves the production cost, but also shortens the assembly time. Of course, the set of magnets 50 sucks the blade 11, which can prevent the planer 10 from falling off the blade 11 without warning. The escape portion 40 helps the blade 11 to withdraw from the assembly groove 30 of the body 20 .
