Description

Woodworking clamp rotating chuck structure

The present invention relates to a woodworking fixture rotary chuck structure that can be used for butting wooden workpieces and temporarily clamping round rod workpieces.

According to the conventional woodworking clamp, as shown in Taiwan Utility Model Patent No. M600243 (the detailed mechanism structure is not described here), the clamp can be operated by reciprocating pressure of the operating handle to control the clamp to temporarily fix the wooden board, wooden block or wooden strip. The clamp of the conventional woodworking clamp is mostly a flat clamp, which can only be used for flat clamping of wooden boards. If it is used for clamping the corners of two wooden board workpieces, a clamp with a V-shaped clamping groove must be used instead. It is known that V-groove chucks can be used to clamp and fix wooden workpieces when they are butted together, but they are still limited to the butt clamping of wooden workpieces. If you want to clamp and fix round rod workpieces on the work table, you must use chucks with V-grooves in different directions, which will inevitably require a lot of different types of chucks to be used as backup; if a V-groove chuck can be used for both butt clamping of wooden workpieces and round rod workpieces, it will inevitably reduce the storage of different types of chucks and improve the inconvenience of replacing chucks.

The main purpose of the present invention is to provide a woodworking clamp rotary clamp structure, which is a woodworking clamp having a clamp body. The clamp body is operated by reciprocating pressing of an operating handle to operate a clamp seat at one end of a shaft to gradually move closer to the clamp body, and the clamp body and the clamp seat are respectively provided with a first clamp arm and a second clamp arm opposite to each other, and a first assembly in the shape of a block is formed on the first clamp arm and the second clamp arm. The invention relates to a first assembly tray and a second assembly tray; at least one V-groove chuck and an extrusion chuck are selectively installed on the first assembly tray and the second assembly tray respectively; the V-groove chuck comprises: an assembly base, which has a frame body, one side end of the frame body is provided with an assembly groove, and a seat surface on the other side end is provided with a buckle neck; the assembly groove is in a notch for the first assembly tray/or the second assembly tray to be embedded, and the first assembly tray is accommodated in a three-sided groove frame The three peripheries of the tray and/or the second set of trays; the buckle neck is divided into multiple sections on a round neck frame to form a guide frame section corresponding to the notch and at least one bearing frame section; a section of buckle strip is formed with a gap between the outer frame surface of the guide frame section and the seat surface, and a positioning point is formed on the inner frame surface different from the end of the section of buckle strip; on the outer frame surface of the bearing frame section, a reverse buckle is formed on the same track as the section of buckle strip corresponding to the guide frame section A V-shaped clip seat is formed with a V-shaped groove frame, and a combination frame is formed at the opposite end of the V-shaped groove. The combination frame is connected to the frame seat body of the assembly base, and has a combination circular groove for the buckle neck to be inserted to allow rotation. The end surface of the combination frame protrudes toward the center of the combination circular groove and has a plurality of ring-shaped block plates arranged inwardly. The part of the block plate is stopped at the buckle strip of the guide frame section and the bearing frame section. On the reverse buckle convex strip, the rotatable buckle neck is restricted from exiting the assembly circular groove. Furthermore, a disc convex body matching the inner frame surface of the guide frame segment is provided on the groove bottom surface of the assembly circular groove. A first limiting point and a second limiting point are provided at a 90-degree interval on the periphery of the disc convex body. The positioning point on the guide frame segment is mutually engaged and positioned with the first limiting point when the front edge line of the V-shaped groove of the V-shaped groove frame is parallel to the embedding direction of the notch. The V-shaped clamp seat rotates to facilitate the displacement of the positioning point and the engagement and positioning with the second limiting point, and adjusts the front edge of the V-shaped clamp groove to be perpendicular to the embedding direction of the notch; The extrusion clamp head is an engaging groove installed on the second assembly disk/or the first assembly disk, and the opposite end of the engaging groove is provided with an extrusion head relative to the V-shaped clamp groove of the V-shaped clamp head; when the front edge of the V-shaped clamp groove of the V-shaped clamp head is parallel to the embedding direction of the notch, the clamp head The operating handle of the main body is pressed back and forth, and the first clamping arm is operated unidirectionally to gradually approach the second clamping arm, so that the V-groove clamping head and the extrusion clamping head can produce a temporary fixed clamping at the corners of the two butted wooden workpieces; when the V-shaped clamping seat is operated to rotate on the assembly base and the front edge of the V-shaped clamping groove is adjusted to be perpendicular to the embedding direction of the notch, the operating handle of the clamping ... When the two clamp arms are close to each other, the extrusion clamp can be supported and placed on the bottom surface of the work table, so that the V-groove clamp can temporarily fix the round rod workpiece on the work table; the overall structure allows the V-shaped clamp seat of the V-groove clamp to be rotated, adjusted and positioned on the assembly base, so that the woodworking clamp can be used for corner clamping and temporary fixation of wooden workpieces when they are connected, and can also add the clamping function of temporarily fixing the round rod workpiece on the work table.

The second purpose of the present invention is to provide a woodworking clamp rotating chuck structure, wherein the buckle neck of the assembly base is formed by dividing the round neck frame into a pair of the bearing frame segments each having the reverse buckle ridge; the number of the blocking pieces for the reverse buckle ridges on the pair of bearing frame segments is increased by a plurality of the blocking pieces, so that the buckle neck of the assembly base is embedded in the assembly circular groove of the V-shaped clamp and connected, which can enhance the ability to prevent backing out.

Another object of the present invention is to provide a woodworking clamp rotary chuck structure, wherein, in the assembly circular groove of the V-shaped clamp seat, on the disk surface of the disk convex body, there is a U-shaped perforated groove forming a spring sheet, and one end of the spring sheet is formed with a high convex portion; when the V-shaped groove chuck is installed on the first assembly disk/or the second assembly disk, the high convex portion is squeezed by the disk surface, and the elastic deformation of the spring sheet produces a pressing effect, so as to increase the positioning of the V-shaped groove chuck on the first assembly disk/or the second assembly disk.

Another object of the present invention is to provide a woodworking clamp rotary chuck structure, wherein the extruding head of the extruding chuck is formed with a pair of clamping inclined surfaces on both sides of a clamping plane, relative to the V-shaped clamping groove of the V-shaped groove frame of the V-shaped groove chuck; so that when the V-shaped groove frame of the V-shaped groove chuck is used to support the outside of the corner where two wooden workpieces are butted, the extruding head of the extruding chuck can be used to support the outside of the corner where two wooden workpieces are butted. The clamping inclined surface squeezes the inner surface of the butt corners of the two wooden workpieces to produce a clamping and fixing effect; when the V-shaped clamping seat of the V-groove clamping head is rotated and adjusted to form the V-shaped clamping groove of the V-groove frame for accommodating a round rod workpiece on the work table, the clamping plane on the extruding head of the extruding clamping head is supported against the bottom surface of the work table, and the round rod workpiece can be clamped and fixed through the V-groove frame.
