Description

Technical Field

[0001] This utility model relates to a saw table, and more particularly to a push rod adjustment structure for a saw table. Background Technology

[0002] In the wood processing industry, the saw table is a commonly used cutting device, and its pusher structure is an important component to ensure the cutting accuracy of wood boards. Ideally, the pusher of the saw table should be perpendicular to the saw blade to achieve precise and efficient cutting operations. However, in actual production, on the one hand, the manufacturing process of the pusher and saw table is affected by factors such as machine tool precision and tool wear, inevitably resulting in dimensional and positional tolerances. On the other hand, during equipment installation, factors such as the operating environment, installation tools, and the skill level of the workers make it difficult to guarantee the perpendicularity of the pusher and saw blade after installation. The errors introduced by the above processing and installation processes will cause angular offset between the pusher and the saw blade, resulting in problems such as beveled edges and inconsistent dimensions in the cut wood boards. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a push rod adjustment structure for a saw table.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A push rod adjustment structure for a saw table includes a table surface mounted on a saw table frame and a push rod mounted on the table surface. A mounting base is fixed to the bottom of the table surface. A rotating base is fixed to one end of the mounting base, and a sliding base whose position is adjusted by an adjustment mechanism is slidably mounted to the other end. A first insert shaft and a second insert shaft are respectively provided on the bottom of the push rod corresponding to the rotating base and the sliding base. The first insert shaft and the second insert shaft are respectively inserted into the rotating base and the sliding base.

[0006] The platform surface is provided with an insertion hole corresponding to the position of the rotating seat. The first insertion shaft passes through the insertion hole and is inserted into the rotating seat. The platform surface is provided with an arc-shaped hole corresponding to the sliding trajectory of the sliding seat. The second insertion shaft passes through the arc-shaped hole and is inserted into the sliding seat.

[0007] The bottom of the sliding seat is fixed with a connector, and the mounting seat is provided with a through hole for the connector to pass through and provide sufficient room for movement. The adjustment mechanism includes a threaded seat, on which a push rod for pushing the connector to slide is threadedly installed.

[0008] The mounting base is also equipped with a slide rail at its bottom, and a slider is slidably mounted on the slide rail. The connector is fixedly connected to the slider, and the end of the push rod abuts against the slider.

[0009] A limiting piece is fixedly installed on one side of the slide rail. The lower end of the limiting piece is provided with a strip-shaped hole along the sliding direction of the slider. A limiting screw is installed on the slider and passes through the strip-shaped hole.

[0010] A spring locking pin is installed at the bottom of the mounting base, and a fixing plate is installed at the bottom of the push ruler corresponding to the spring locking pin. The fixing plate is provided with a pin hole, and the pin of the spring locking pin is inserted into the pin hole.

[0011] The platform and the mounting base are respectively provided with a first through hole and a second through hole for the fixing piece to pass through.

[0012] The bottom of the pusher is provided with a groove that extends through both ends. A fixing block is installed in the groove corresponding to the first insertion shaft and the second insertion shaft. The first insertion shaft and the second insertion shaft are installed on the corresponding fixing block.

[0013] The beneficial effects of this utility model are as follows: A mounting base is fixed to the bottom of the tabletop. A rotating base is fixed to one end of the mounting base, and a sliding base with an adjustable position is slidably mounted on the other end. A first insert shaft and a second insert shaft are respectively provided on the bottom of the pusher corresponding to the rotating base and the sliding base. The first insert shaft and the second insert shaft are inserted into the rotating base and the sliding base respectively. The position of the sliding base is adjusted by the adjusting mechanism, thereby causing the entire pusher to rotate around the rotating base. This effectively compensates for the angular deviation between the pusher and the saw blade caused by processing and installation errors, ensuring the perpendicularity of the cutting process and improving the accuracy of wood cutting.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0020] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0021] Reference Figure 1-3 A push rod adjustment structure for a saw table includes a table surface 1 mounted on a saw table frame and a push rod 2 mounted on the table surface 1. A mounting base 3 is fixed to the bottom of the table surface 1, and the mounting base 3 can also be fixed to the saw table frame. A rotating base 4 is fixed to one end of the mounting base 3, and a sliding base 5, whose position is adjusted by an adjustment mechanism 6, is slidably mounted to the other end. A first insert shaft 7 and a second insert shaft 8 are respectively provided on the bottom of the push rod 2 corresponding to the rotating base 4 and the sliding base 5. The first insert shaft 7 and the second insert shaft 8 are correspondingly inserted into the rotating base 4 and the sliding base 5. The position of the sliding base 5 is adjusted by the adjustment mechanism 6, thereby causing the entire push rod 2 to rotate around the rotating base 4. This effectively compensates for the angular offset between the push rod and the saw blade caused by processing and installation errors (the angular error of the push rod is small, generally within 2°), ensuring the perpendicularity of the cutting process and improving the accuracy of wood cutting.

[0022] An insertion hole 9 is provided on the platform 1 corresponding to the position of the rotating seat 4. The first insertion shaft 7 passes through the insertion hole 9 and is inserted into the rotating seat 4. An arc-shaped hole 10 is provided on the platform 1 corresponding to the sliding trajectory of the sliding seat 5. The arc-shaped hole 10 can also be a strip hole of a considerable size or other hole structure, as long as it does not affect the sliding of the sliding seat 5. The second insertion shaft 8 passes through the arc-shaped hole 10 and is inserted into the sliding seat 5.

[0023] The bottom of the sliding seat 5 is fixed with a connector 11. The mounting base 3 is provided with a through hole 12 for the connector 11 to pass through and provide sufficient room for movement. The adjustment mechanism 6 includes a threaded seat 13. A push rod 14 for pushing the connector 11 to slide is threadedly installed on the threaded seat 13. The end of the push rod 14 is provided with a hand-tightening part 28. When the user rotates the push rod 14 through the hand-tightening part 28, the push rod 14 extends through the threaded structure and pushes the sliding seat 5 to slide through the connector 11, thereby compensating for the angular offset between the push ruler 2 and the saw blade.

[0024] Furthermore, a slide rail 15 is also installed at the bottom of the mounting base 3, and a slider 16 is slidably mounted on the slide rail 15. The connecting piece 11 is fixedly connected to the slider 16, and the end of the push rod 14 abuts against the slider 16, which can effectively improve the sliding stability of the sliding base 5.

[0025] The adjustment mechanism 6 is equipped with corresponding scales (using existing, conventional settings) for intuitive observation of the extension and retraction distance of the push rod 14.

[0026] A limiting piece 17 is fixedly installed on one side of the slide rail 15. The lower end of the limiting piece 17 is provided with a strip hole 18 along the sliding direction of the slider 16. A limiting screw 19 is installed on the slider 16 and passes through the strip hole 18.

[0027] When adjusting the angle of the push ruler 2, retract the push rod 14, first loosen the limiting screw 19, allowing the slider 16 to slide on the slide rail 15, push the push ruler 2 so that the slider 16 abuts against the end of the push rod 14 (by visual inspection, it can be clearly seen that the angle between the push ruler and the saw blade is less than 90°; if visual inspection is not possible, tools such as an angle gauge can be used for assistance). At this time, tighten the hand-tightening part 28 to extend the push rod 14, pushing the sliding seat 5 to slide through the connecting piece 11. Once the push ruler is perpendicular to the saw blade (use tools such as angle gauges for assistance, or take a piece of wood with a right angle, place one side of the right angle against the side wall of the saw blade, and when the other side is completely against the push ruler, it can also be judged that the push ruler is perpendicular to the saw blade), turn the limiting screw 19 to press the limiting screw 19 against the limiting piece 17. The increased pressure increases the friction, thereby fixing the slider 16 to the slide rail 15 and preventing the push ruler 2 from swinging again, thus completing the adjustment of the push ruler 2.

[0028] A spring locking pin 20 is installed at the bottom of the mounting base 3. A fixing plate 21 is installed at the bottom of the push ruler 2 corresponding to the spring locking pin 20. The fixing plate 21 is provided with a pin hole 22. The platform 1 and the mounting base 3 are respectively provided with a first through hole 24 and a second through hole 25 for the fixing plate 21 to pass through. After the fixing plate 21 passes through the first through hole 24 and the second through hole 25, the pin 23 of the spring locking pin 20 is aligned with the pin hole 22. The pin 23 is inserted into the pin hole 22 to prevent the push ruler 2 from being directly removed during use, which would require readjustment.

[0029] The spring locking pin 20 includes a pin seat, and the pin 23 is repositionably installed in the pin seat by a first spring. The pin 23 is provided with a slot, and the pin seat is provided with a pressing member 29 that is reset by a second spring corresponding to the slot. When the pin 23 is pushed until the pressing member 29 is aligned with the slot, the second spring resets and drives the pressing member 29 to insert into the slot. At this time, the pin 23 cannot be withdrawn. When the pressing member 29 is pressed, the pressing member 29 withdraws from the slot. At this time, the first spring resets and pushes the pin 23 out of the pin hole 22.

[0030] The bottom of the pusher 2 is provided with a groove 26 that runs through both ends. A fixing block 27 is installed in the groove 26 corresponding to the first insertion shaft 7 and the second insertion shaft 8. The first insertion shaft 7 and the second insertion shaft 8 are installed on the corresponding fixing block 27. The fixing block 27 can be adjusted according to the actual position of the rotating seat 4 and the sliding seat 5 to achieve the effect of being suitable for different installation sizes.
