Description

Technical Field

[0001] This utility model belongs to the field of machining technology and relates to an improvement in the cutting and processing of non-ferrous metals. Background Technology

[0002] Currently, in the mass production of aluminum profiles, the single-head saw clamping mechanism occupies a 100-200mm clamping section at the end of the profile, making this section an unusable process head. The current process requires offline storage and secondary sawing of the head, leading to increased labor time and material waste. Summary of the Invention

[0003] The purpose of this utility model is to provide an auxiliary clamping and length-fixing mechanism for sawing aluminum square tubes. As a detachable auxiliary clamping mechanism, it transfers the sawing clamping position from the profile to the mechanism, releases the full length of the square tube to be cut, realizes online sawing of the process material head, and reduces secondary processing costs.

[0004] The technical solution includes a clamping square tube and a connecting block;

[0005] In the positioning structure, the clamping square tube has a positioning groove, and the corresponding position of the connecting block has a positioning protrusion. The connecting block slides into the positioning groove to achieve positioning, ensuring no relative movement during sawing. In the replacement design structure, the clamping square tube and the connecting block are detached and connected by countersunk screws, which connect the screw hole of the clamping square tube to the fixing thread of the connecting block. This facilitates the replacement of connecting blocks of different specifications to accommodate square tubes with different wall thicknesses.

[0006] In the anti-slip structure, the outer surface of the clamping square tube is provided with anti-slip texture to increase the contact friction coefficient of the clamping mechanism and prevent displacement caused by sawing vibration.

[0007] The beneficial effects of this utility model are:

[0008] 1. Online utilization of material head: By using the single-head saw clamping mechanism on this auxiliary mechanism, the problem of traditional clamping section occupation is eliminated, allowing the process material head to participate in online sawing, increasing the fixed length and improving efficiency; 2. Flexible adaptation: Countersunk screw connection + modular connecting block design, quick replacement to adapt to square tubes with different wall thicknesses / cavity sizes, improving the versatility of the production line.

[0009] 3. Sawing stability: Anti-slip texture inhibits clamping slippage, and the positioning groove and positioning protrusion cooperate to prevent movement and torsion, ensuring sawing quality;

[0010] 4. Cost-effectiveness: Eliminating the secondary processing step of the material head reduces the processing time of a single profile and improves material utilization. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings:

[0015] In the diagram: 1 is the clamping square tube; 2 is the connecting block; 3 is the square tube to be cut; 11 is the anti-slip texture of the clamping square tube; 12 is the positioning groove of the clamping square tube; 13 is the screw hole of the clamping square tube; 21 is the first chamfer of the connecting block; 22 is the end of the connecting block extending into the clamping square tube; 23 is the positioning protrusion of the connecting block; 24 is the fixing thread of the connecting block; 25 is the boss of the connecting block; 26 is the end of the connecting block extending into the square tube to be cut; 27 is the second chamfer of the connecting block.

[0016] The connecting block's protruding end is inserted into the clamping square tube cavity. Positioning is achieved through the engagement of the connecting block's positioning protrusion and the clamping square tube's positioning groove, followed by tightening with countersunk screws. During sawing, the connecting block is inserted into the cavity of the square tube to be cut, and the single-head saw clamping mechanism directly clamps this auxiliary mechanism, thus releasing the entire length of the square tube to be cut for effective sawing. Anti-slip textures are provided on the top of the clamping square tube to increase friction during clamping. Compared to traditional sawing, this mechanism, by transferring clamping to the auxiliary mechanism, transforms the entire length of the square tube to be cut into an effective sawing segment.

[0017] like Figures 1 to 3 As shown, the aluminum square tube sawing auxiliary clamping and length-fixing mechanism includes a clamping square tube (1) and a connecting block (2).

[0018] Insert the end (22) of the connecting block (2) into the cavity of the clamping square tube (1) so that the positioning protrusion (23) is embedded in the positioning groove (12) to complete the positioning restriction;

[0019] The countersunk screws are tightened into the fixing threads (24) of the connecting block through the screw holes (13) of the clamping square tube, making them a single unit. The connecting block has a chamfer (21) to assist in the insertion.

[0020] Before sawing and feeding, insert the connecting block into the end (26) of the square tube to be cut and insert it into the inside of the square tube (3). The chamfered corner (27) of the connecting block assists in the insertion. Make the end face of the connecting block boss (25) fit tightly with the end face of the square tube (3) to be cut. Then, use this side as the clamping end of the clamping mechanism. The clamping square tube (1) is provided with anti-slip texture to increase friction during clamping.

[0021] When the single-head saw is cutting, the single-head saw clamping mechanism is clamped on the auxiliary clamping mechanism instead of directly clamping the square tube (3) to be cut. This avoids the clamping mechanism occupying the effective length of the square tube (3) to be cut, so that the 100-200mm process material head that could not be used due to clamping can be cut online in one go, increasing the number of cut lengths.
