Description

Technical Field

[0001] The present invention relates to a jig used when performing shape processing of any dimension at an arbitrary position of a material using an electric router or an electric trimmer.

Background Art

[0002] Conventionally, for jigs for commonly used electric routers and electric trimmers, it has been necessary to prepare individual jigs for each processing shape. Therefore, every time different-shaped processing is performed, a dedicated jig corresponding thereto has to be prepared each time. For example, in the jig described in Design Registration No. 1518695, it is necessary to adjust the position of the guide according to the thickness of the processed material, and furthermore, the types of tools that can be used are limited. Also, in Design Registration No. 1641580, although a device for easily sandwiching the processed material is provided, there is a problem that the applications are limited because the types of machines and blades that can be used are limited.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In woodworking, an object is to provide a highly versatile jig that enables processing of arbitrary dimensions and shapes while corresponding to various blades using an electric router or an electric trimmer. Conventionally, since it has been necessary to prepare individual jigs for each processing application, the work efficiency has been poor, and it has also been troublesome for management and storage. In contrast, this invention achieves rationalization of work and versatility of the jig by providing a configuration that can handle a variety of processing with a single jig. [Means for solving the problem]

[0005] The various guides on this jig have a movable structure, allowing the position and angle of the guides to be freely set according to the shape of the workpiece. This enables machining of a wide variety of shapes. In addition, an attachment is fitted to the back of the jig to assist in fixing it to the material, enabling easy installation at the machining position. [Effects of the Invention]

[0006] The freely movable guide of this jig allows it to flexibly accommodate various machining shapes. Therefore, it can replace multiple dedicated jigs that previously needed to be prepared individually, contributing to increased work efficiency and simplification of the equipment. [Brief explanation of the drawing]

[0007] [Figure 1] This figure shows the surface of the jig of the present invention. [Figure 2] This figure shows the processing opening and dimensions of the jig of the present invention. [Figure 3] This is a diagram of the guide and blade for trimmers and routers. [Figure 4] This diagram shows the jig of the present invention with an attachment for processing small edges attached to the back surface. [Figure 5] This diagram shows the back side of the jig of the present invention with a planar machining attachment installed. [Modes for carrying out the invention]

[0008] In Figure 1, a support plate (2) is provided with two separate points (D) on the horizontal center line (B) of the base plate (surface) (1) as its axis of rotation. A horizontal guide (3) is provided parallel to the horizontal center line (B), and it is connected to the support plate (2) at point (E). Point (E) serves as the starting point for sliding the horizontal guide (3) along the horizontal center line (B). These points (D) and (E) are fixed by screws, nuts, etc., and by rotating the support plate (2), it is possible to slide the horizontal guide (3) and the support plate (2). A vertical guide (4) is provided perpendicular to the horizontal guide (3). The vertical guide (4) is provided with a groove (5) that allows it to slide along the horizontal guide (3). By tightening the screw (6), the vertical guide (4) can be fixed perpendicular to the horizontal guide (3), and by tightening the nut (7) of the screw fitted into the inverted T-shaped groove, both the vertical and horizontal guides (3) and (4) can be securely fixed. Furthermore, the base plate (1) is provided with rulers (9) and (8) indicating the distance from the center lines (B) and (C), allowing the internal dimensions between the guides to be checked and set to the desired dimensions.

[0009] In Figures 4 and 5, the attachment on the base plate (back) (1) can be replaced by removing the nut (10) provided on the base plate (front) (1). Figure 4 shows the attachment for processing end grain and small edges. A support plate (11) is provided with two separate points (F) on the horizontal center line (B) of the base plate (back side) (1) as the axis of rotation. A horizontal guide (12) is provided parallel to the horizontal center line (B), and this is connected to the support plate (11) at point (G). Point (G) is the starting point for sliding the horizontal guide (12) to move parallel along the horizontal center line (B). By clamping the material with the horizontal guide (12), the horizontal center line (B) of this jig can be aligned with the end grain and small edge center line of the material. It can handle processing materials of various thicknesses, and by simply clamping the material with the horizontal guide (12), this jig can be easily placed in the center of the end grain and small edge without measuring the thickness of the material. (3) Figure 5 shows the state with the attachment for surface machining attached. The horizontal guide (16) is an attachment for machining on a plane at a predetermined dimension from the edge of the material. The support plate (15) of the horizontal guide slides in a direction perpendicular to the horizontal center line (B). The horizontal guide (16) is movable parallel to the horizontal center line (B). Also, a scale (14) indicating the distance from the center line is provided on the base plate (1), and the dimension between the attachment and the center of the material can be confirmed.

Example

[0010] The method of using the guide for machining will be described using FIGS. 2 and 3. Let the machining dimension in the horizontal direction be (a). Let the machining dimension in the vertical direction be (b). Let the distance from the outer end of the machining blade (γ) to the outer end of the guide (β) attached to the power tool for machining be (c). The distance (x) inside the horizontal guide (3) = (a) + 2(c) The distance (y) inside the vertical guide (4) = (b) + 2(c) Just set as above. In addition, to fix the jig to the material, use the attachment provided on the back surface of the base plate (1) to install the jig at a predetermined position, and use a clamp or the like to fix it integrally with the material.
