[0001] This utility model specifically relates to an all-aluminum saw table, belonging to the field of saw table technology. Background Technology

[0002] A saw table is a platform used for sawing and processing wood. It is equipped with cutting equipment to complete the sawing task. In use, the wood is placed on a sliding table on the platform, and the cutting equipment is pushed across the table to cut the wood. Existing saw table structures, such as the portable woodworking push-table saw disclosed in Chinese Patent Publication No. CN213532962U, include a saw table support, worktable, push rod, positioner, backrest, extension plate, dust collection device, guide rail, slide rail flow strip, and milling machine hole. This structure features a detachable extension frame and extension plate, increasing the effective working area of ​​the saw table and enhancing the flexibility and convenience of cutting. The saw table support is made of detachable steel pipe, making it portable, practical, and easy to transport. However, existing saw tables have the following drawbacks: First, the adjustment of the sliding platform and the height of the cutting saw on the saw table is cumbersome and cannot be precisely adjusted, which can easily cause cutting errors. Second, the sliding table lacks effective anti-derailment or limit protection devices, which poses a risk of loss of control when pushing materials at high speed or under heavy load. Third, the perpendicularity between the support unit and the cutting equipment cannot be adjusted. Finally, the saw table legs cannot be set to open and close according to the user's needs. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes an all-aluminum saw table that allows for precise adjustment of the opening and closing angles of the saw table legs, as well as the verticality adjustment of the backing unit and the cutting equipment. It also allows for adjustment of the height difference between the cutting equipment and the slide assembly, thus ensuring processing accuracy.

[0004] The all-aluminum saw table of this utility model includes: The main frame includes a square frame with a crossbeam along its width inside. Corner brackets are fixed at the inner corners of the frame and between the frame and the crossbeam. Support legs are fixed to the bottom of the frame corners via folding hinges, and casters with brakes are fixed to the bottom of each support leg. Folding supports are provided between the support legs and the main frame. The frame, crossbeams, and support legs are all made of aluminum profiles. Limit springs are fixed directly opposite each other inside the frame. A flow strip assembly, wherein the frame is hollow at its length end, the flow strip assembly includes a pull-out frame that is movably inserted into the frame, a guide rail is fixed to the top of the pull-out frame, and a row of guide wheels is rotatably arranged on the inner side of the guide rail; The slide assembly includes two lower guide rails fixed to the top surface of the frame in the width direction. An upper guide rail is slidably mounted on the top of the lower guide rails, and a slide frame base is fixed to the top surface of the upper guide rail. A slide panel is fixed to the top surface of the slide frame base. A limit plate is fixed to the inner side of the slide frame base opposite to the limit spring. Self-locking locks that cooperate with each other are provided on the inner side of the frame and the bottom inner side of the slide frame base. A locking nut is slidably mounted on the outer side of the slide frame base in the traveling direction of the lower guide rails. A positioning pin fixing plate is attached to the outer side of the slide frame base. An adjusting bolt that is screwed onto the positioning pin fixing plate is provided on the positioning pin fixing plate and a backing positioning pin is also fixed on the positioning pin fixing plate. An adjustment frame assembly is fixed to the top of the frame and is arranged side by side with the slide assembly; The backing unit includes an aluminum profile strip, the bottom of which is slidably fixed with a clamping seat, which is inserted into and limited by a backing positioning pin; the top of the aluminum profile strip is slidably fixed with a right-angle support by bolts.

[0005] The main frame has a square tube structure along its length, which can accommodate flow strips. The folding support is fixed to a leg at one end and can rotate on the leg, while the other end moves along the aluminum profile groove of the frame, allowing the leg to fold or adjust its opening angle. After adjustment, the folding support can be locked in place with the aluminum profile groove. The casters with brakes allow for easy movement of the saw table when unlocked, and are securely locked when locked. Limiting springs are installed on the main frame, which cooperate with the limiting plates on the slide. When the slide slides to its end, the limiting springs on the main frame limit the slide, preventing it from sliding out and also reducing vibration and noise, avoiding rigid impact between the limiting plates and the main frame. The pull-out frame of the fluid strip assembly can be pulled out on the frame to adapt to different widths of boards. The pull-out frame supports the guide rails, and the guide wheels on the guide rails support the boards and guide the sliding movement of the boards during cutting. The slide table assembly uses a lower guide rail and an upper guide rail. The lower guide rail serves as a fixed track and is fixed to the top surface of the frame, while the upper guide rail serves as a moving track and slides with the top of the lower guide rail, enabling linear sliding of the slide table frame and the slide table panel. The slide table frame is made of aluminum profile with aluminum profile grooves on all four sides. A locking nut is installed in the aluminum profile groove on the outside of the slide table frame. The locking nut can slide within the aluminum profile groove and its circumferential rotation is restricted by the inner wall of the aluminum profile groove. At this time, the adjusting bolt on the positioning pin fixing plate rotates with the locking nut to lock the adjustment position. The backing positioning pin facilitates the clamping of the backing unit. The positioning pin fixing plate can slide along the aluminum profile groove to facilitate the adjustment of the perpendicularity of the backing unit to the saw head and saw blade. After use, the slide table frame is moved to overlap with the frame. At this time, the self-locking lock achieves self-locking between the slide table frame and the frame, preventing the slide table frame from sliding arbitrarily when not in use. When sawing operations are required, the self-locking lock can be manually unlocked. The adjusting frame assembly is used to install various sawing equipment. The adjusting frame assembly and the slide assembly are set up side by side. When the slide assembly passes through the adjusting frame assembly, the plate on the slide assembly can be sawn by the sawing equipment. The aluminum profile strip of the backing unit enables the vertical positioning of the plate, and the right-angle support that slides at the top of the aluminum profile strip can adjust the horizontal backing position of the plate and provide horizontal positioning.

[0006] Furthermore, the adjustment frame assembly includes an adjustment frame base, on which a saw head table for mounting the cutting saw is provided, and a router plate for mounting the router is provided on the side of the saw head table; the adjustment frame base is fixed to the frame of the main frame, and the adjustment frame base is used to mount the saw head table and the router plate; thus realizing the hanging and installation of the sawing equipment on the saw table.

[0007] Furthermore, the lower guide rail includes a base plate fixed to the top surface of the frame, and an optical axis assembly is fixed on the base plate; the upper guide rail includes a linear bearing that is fitted and fixed to the slide frame; the linear bearing is slidably installed with the optical axis; through the cooperation of the linear bearing and the optical axis assembly, the slide frame can achieve high linearity sliding.

[0008] Furthermore, the lower end of the folding support is fitted with a shoulder screw via a nylon washer, and the shoulder screw is fastened to a first nut body provided on the inner side of the support leg; the upper end of the folding support is rotatably provided with an opening / closing bolt, which is screwed to a second nut body, and the second nut body is slidably disposed on the inner side of the outer groove in the length direction of the frame; a third nut body is slidably disposed on the side of the folding hinge of the frame, and the third nut body is screwed to a limit bolt; The lower end of the folding support is fastened to the support leg by a shoulder screw and a first nut body, and the lower end of the folding support can rotate on the shoulder screw; the upper end of the folding support is limited in the aluminum profile groove of the frame by an opening and closing bolt and a second nut body, and the second nut body can slide along the aluminum profile groove to realize the adjustment of the opening and closing angle of the folding support. After the adjustment is completed, the rotation angle is locked by rotating the opening and closing bolt; and the rotation angle position is further locked by the cooperation of the third nut body and the limiting bolt, which is convenient for the user to remember the position.

[0009] Furthermore, the adjusting frame base is composed of two sets of adjusting frame longitudinal beams and two sets of adjusting frame transverse beams spliced ​​together. An adjusting screw is screwed onto the bottom of the adjusting frame base at the saw head frame. An angle iron is fixed to the frame body by bolts, and an adjusting column is fixed to the other right-angle side of the angle iron. An adjusting bolt is screwed onto the section of the adjusting column away from the angle iron.

A fine-tuning nut is slidably mounted on the adjusting column and the frame body, and a fine-tuning bolt that screws onto the fine-tuning nut is provided outside the connecting plate.

[0010] Both the longitudinal and transverse beams of the adjustment frame are made of aluminum profiles and are spliced ​​together to form an adjustment square frame. Adjustment screws are screwed to the bottom of the adjustment square frame. These screws allow for fine-tuning of the saw head table at the mounting point of the saw head frame. After adjustment, the saw head table can be fastened to the adjustment square frame with bolts. Fine-tuning of the height of the adjustment frame base is achieved by adjusting the uprights and their auxiliary components, as detailed below: The adjusting column is fixed to the frame by angle iron. The fine-tuning screw at the top of the adjusting column supports the longitudinal beam of the adjusting frame. When a screwdriver is inserted through the process hole, the fine-tuning screw can be rotated to adjust the longitudinal beam of the adjusting frame upwards or downwards. During adjustment, the adjusting bolt on the adjusting column slides up and down along the vertical groove. After the adjustment is completed, the height difference between the adjusting frame base and the slide table assembly can be adjusted, and the adjusting bolt can be locked and fixed. After the adjusting frame base is adjusted, the connecting plate is used to connect and fix the adjusting frame platform to the main frame to enhance stability during transportation.

[0011] Furthermore, the self-locking device is an electromagnet installed on the inner side of the frame and the bottom of the inner side of the slide frame; the position of the frame and the slide frame can be locked by the mutual attraction of the electromagnets.

[0012] Furthermore, the self-locking lock is a self-locking pin located on the inner side of the frame. The pin is movably locked with a locking piece fixed to the bottom inner side of the slide frame. The pin and the locking piece can automatically lock together. When unlocking is required, the pin needs to be manually reset.

[0013] Compared with existing technologies, the all-aluminum saw table of this invention utilizes aluminum profiles to construct the main frame, slide assembly, and support unit. It leverages the guide rail feature on all four sides of the aluminum profile to precisely adjust the opening and closing angles of the saw table legs, and uses limit bolts to memorize the opening and closing angles. It also allows for sliding adjustment of the support unit, enabling vertical adjustment between the support unit and the cutting equipment. Furthermore, by adjusting the column and its accessories, the height difference between the adjustment frame assembly and the slide assembly can be precisely finely adjusted. Simultaneously, by adjusting screws, the height difference between the saw table surface and the slide assembly can be individually and precisely finely adjusted, ensuring processing accuracy.
