Description

Technical Field

[0001] This utility model belongs to the technical field of sawing tables, specifically relating to a simple woodworking sawing table. Background Technology

[0002] The core structure of a typical saw table typically includes side supports, a tabletop, the saw, and a backrest. In wood cutting operations, the relative positions of the saw and the table in existing simple saw tables are fixed. This prevents the proper distribution of the contact area between the board and the tabletop during cutting, causing the board to easily fall off the tabletop. Furthermore, existing simple saw tables lack perforations in the tabletop and frame, making the saw table heavy, inconvenient to carry, and increasing manufacturing costs. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a simple woodworking saw table, which solves the problem that existing simple woodworking saw tables are not lightweight enough for handling and reduces the risk of boards falling off when being cut.

[0004] This utility model is achieved through the following technical solution: a simple woodworking saw table, including a mounting frame, a bracket, and a movable plate slidably mounted on the mounting frame. The mounting frame is fixed to the upper end of the bracket. The mounting frame and the movable plate form the saw table surface. The mounting frame is also provided with a backrest for fastening onto the saw table surface during cutting. An inverted saw assembly is mounted on the lower surface of the movable plate. A support strip is provided in the middle of the mounting frame. The upper surface of the support strip is lower than the upper surface of the mounting frame by the thickness of the movable plate. The movable plate is embedded in the mounting frame, with its front and rear edges abutting against the front and rear inner walls of the mounting frame. The width of the movable plate is less than the distance between the left and right inner walls of the mounting frame. Support plates are provided on the inner walls at both the front and rear ends of the mounting frame. The support plates have several strip-shaped holes. Locking screws are provided on both sides of the lower surface of the movable plate, corresponding to the positions of the strip-shaped holes. The locking screws pass through the strip-shaped holes from the bottom surface of the support plate and are connected and fixed to the locking screw holes on the movable plate.

[0005] Furthermore, the upper surface of the support plate is flush with the upper surface of the support bar; the locking screw hole on the movable plate is formed by a nut embedded in the lower surface of the movable plate.

[0006] Furthermore, the locking screw is a long screw with an extension rod and a knob, and a limiting nut is also connected to it. When the connection is locked, the limiting nut is attached to the lower surface of the support plate.

[0007] Furthermore, the inverted saw assembly includes a saw blade and a saw drive component, the saw blade being arranged parallel to each other relative to the mountain, and there is a gap between the saw blade and the edge of the movable plate.

[0008] Furthermore, scales are provided on both the front and rear sides of the movable plate near the edges of the mounting frame. The projection of the plane containing the saw surfaces on both sides of the saw blade onto the scales is two zero-point scale lines. Scale values ​​with opposite measurement directions are provided extending to the left and right sides from the zero-point scale lines. The distance between the two zero-point scale lines is equal to the thickness of the saw blade.

[0009] Furthermore, the mounting frame has supplementary reading scale lines on both the front and rear sides, which are parallel to the scale and are extensions of the scale values ​​on both sides of the scale.

[0010] This invention allows for greater flexibility in the distance between the saw blade and the support plate on both sides of the inverted saw assembly by moving the movable plate left and right. This results in a larger contact area between the board and the saw table surface when cutting boards of different sizes. The movable plate is adjusted by sliding along the left and right direction on the support bar in the middle of the mounting frame. Since the width of the movable plate is smaller than the width of the mounting frame, a hollow structure is formed between the movable plate and the mounting frame (i.e., on the saw table surface), allowing the movable plate to move on the mounting frame to adjust its position. After the movable plate moves to a suitable position and remains stationary, a locking screw is inserted through the slotted hole on the bottom of the support plate and screwed into the locking screw hole on the movable plate. This locks the support bar with the locking screw and the movable plate, achieving a fixed effect. When the cutting size needs to be readjusted, the locking screw is removed and the movable plate is moved and fixed again. The operation is simple, the adjustment is flexible and convenient, and the adjustment efficiency is high. The hollow structure design of the table surface reduces the overall weight of the saw table, making it easy to carry and saving manufacturing costs. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0020] like Figures 1-6 As shown, this utility model describes a simple woodworking saw table, including a mounting frame 2, a support, and a movable plate 1 slidably mounted on the mounting frame 2. The mounting frame 2 is fixed to the upper end of the support. The mounting frame 2 and the movable plate 1 form the saw table surface, and the mounting frame 2 has a hollow structure. The mounting frame 2 is also provided with a support 4 for fastening onto the saw table surface during cutting. An inverted saw assembly is mounted on the lower surface of the movable plate 1. A support strip 21 is provided in the middle of the mounting frame 2. The upper surface of the support strip 21 is lower than the upper surface of the mounting frame 2 by the thickness of the movable plate 1. The movable plate 1 is embedded in the mounting frame 2, with its front and rear edges abutting against the front and rear inner walls of the mounting frame 2. The width of the movable plate 1 is smaller than the distance between the left and right inner walls of the mounting frame 2. Support plates 22 are provided on the inner walls at both the front and rear ends of the mounting frame 2. The support plates 22 are provided with a plurality of strip holes 221. Locking screw holes 11 corresponding to the positions of the strip holes 221 are provided on both sides of the lower surface of the movable plate 1, and locking screws 5 are connected thereto. The locking screws 5 pass through the bottom surface of the support plate 22 into the strip holes 221 and are connected and fixed to the locking screw holes 11 on the movable plate 1.

[0021] This invention allows for greater flexibility in the distance between the support plate 4 and the left and right sides of the saw blade of the inverted saw assembly by moving the movable plate 1 left and right. This results in a larger contact area between the board and the saw table surface when cutting boards of different sizes. The movable plate 1 is adjusted by sliding along the left and right direction on the support bar 21 in the middle of the mounting frame 2. Since the width of the movable plate 1 is smaller than the width of the mounting frame 2, a hollow structure is formed between the movable plate 1 and the mounting frame 2 (i.e., the saw table surface). The movable plate 1 can move on the mounting frame 2 to adjust its position. After the movable plate 1 is moved to a suitable position and remains stationary, the locking screw 5 passes through the strip hole 221 from the bottom surface of the support plate 22 and is screwed into the locking screw hole 11 on the movable plate 1. Thus, the locking screw 5 and the movable plate 1 clamp the support bar 21 to achieve a fixed effect. When it is necessary to readjust the cutting size, the locking screw 5 can be removed and the movable plate 1 can be moved to fix it again. The operation is simple, the adjustment is flexible and convenient, and the adjustment efficiency is high. The hollow structure design of its table reduces the overall weight of the saw table, making it easy to carry and saving manufacturing costs.

[0022] The upper surface of the support plate 22 is flush with the upper surface of the support bar 21; the locking screw hole 11 on the movable plate 1 is formed by a nut embedded in the lower surface of the movable plate 1 (that is, a nut is pressed in or welded into the lower surface of the movable plate 1 after a hole is opened); when locking, a shorter locking screw 5 can be passed through the strip hole 221 from the lower surface of the support plate 22 and connected to the nut for locking. The thread length of the locking screw is less than the sum of the thickness of the support plate 22 and the height of the nut.

[0023] Considering that the installation direction of the locking screw 5 is from bottom to top, it may cause inconvenience for the operator to squat down under the table during installation. In this embodiment of the utility model, the external thread length of the locking screw 5 is equal to the sum of the internal thread length of the locking screw hole 11 and the thickness of the support plate 22. The locking screw 5 is provided with a limiting nut 51, an extension rod 52 and a knob 53 in sequence from the lower end of the external thread (please refer to...). Figure 4 Therefore, during installation, the operator only needs to hold the extension rod 52 and the knob 53, insert the threaded end of the locking screw 5 into the slot 221 and the locking screw hole 11, and then tighten the knob 53 until the limit nut 51 abuts against the slot 221. Since the support plate 22 is located at the edge of the mounting frame 2, the operator can find the insertion position by feeling even without squatting down. The extension rod 52 is easy to hold and the knob 53 is easy to apply force without the need for screwdrivers or other tools, making the installation operation more convenient and labor-saving. In addition, the knob 53 can be set to be larger for easy rotation.

[0024] like Figure 1 and Figure 3 As shown, in this embodiment of the utility model, the inverted saw assembly includes a saw blade 3 and a saw drive component. The saw blade 3 is arranged parallel to the support 4, and there is a gap between the saw blade 3 and the edge of the movable plate 1. The inverted saw assembly is located on the left / right side or in the middle of the movable plate 1. For example, in some embodiments, the inverted saw assembly can be set to be located on the left side of the movable plate 1, so there is a gap between the saw blade 3 and the left edge of the movable plate 1. In use, the support 4 can be adjusted and installed in a suitable position on the mounting frame 2 according to the size of the plate to be cut. If the size of the plate to be cut is large, the support 4 can be installed on the right side of the saw blade 3 (e.g., Figure 1 As shown), the distance between the support 4 and the saw blade 3 can be adjusted from 0 to 60 units. If the size of the board to be cut is small, the support can be installed on the left side of the saw blade (e.g., Figure 3 As shown), the distance between the support 4 and the saw blade 3 can be adjusted from 0 to 20 units. The distance between the support 4 and the left and right sides of the saw blade 3 is more flexible and convenient, and the contact area between the board and the saw table is reasonably distributed. The boards cut into two halves are kept on the installation frame 2 to prevent the boards from falling.

[0025] It should be noted that the saw blade 3 in the inverted saw assembly is usually circular in shape, and the upper part of the circular saw blade 3 extends out of the upper surface of the movable plate 1. The saw blade drive component in the inverted saw assembly needs to be fixed on the lower surface of the movable plate 1. Therefore, the support strip 21 in the middle of the mounting frame 2 is distributed on the front and rear sides of the saw blade 3. When the movable plate 1 moves left and right, the saw blade drive component below it moves left and right synchronously. The support strip 21 can thus provide a buffer for the movement of the saw blade drive component.

[0026] Furthermore, scales 12 are provided on both the front and rear sides of the movable plate 1 near the edges of the mounting frame 2. The projection of the plane containing the saw surfaces on both sides of the saw blade 3 onto the scales 12 is two zero-point scale lines. Scale values ​​with opposite measurement directions are provided extending to the left and right sides from the zero-point scale lines. The distance between the two zero-point scale lines is equal to the thickness of the saw blade 3. Thus, after adjusting the mounting position of the backrest 4 to the other side of the saw blade 3, data can also be measured according to the reverse scale values.

[0027] A further technical solution is, such as Figure 6 As shown, the front and rear sides of the mounting frame 2 are provided with supplementary reading scale lines 23 that are parallel to the scale 12. The supplementary reading scale lines 23 are extensions of the scale values ​​on both sides of the scale 12. In other words, the supplementary reading scale lines 23 correspond to the width values ​​of the hollow areas on both sides of the movable plate 1 on the mounting frame 2. When the backrest 4 is installed on the hollow area, the cutting dimensions of the plate can be accurately read by combining the scale 12 and the supplementary reading scale lines 23, avoiding the trouble of using a measuring ruler for measurement and marking.

[0028] It should be noted that some structures in the illustrations of this utility model are shown by dashed lines, which means that these structures are not visible from the current viewpoint. The dashed lines are used to illustrate the positional relationship between the structures and to facilitate understanding.

[0029] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
