Description

Technical Field

[0001] The invention relates to the field of standard section processing equipment, and in particular to an outer wall grinding mechanism for a standard section support rod tenon after welding. Background Art

[0002] Tenons are provided at both ends of each strut of the standard section. The current docking method is to first clamp the strut and the tenon on the welding mold to dock the strut with the tenons at both ends by spot welding, and then weld the joints between the strut and the tenon by welding comparison, so as to ensure the welding strength of the strut and the tenon. The current robotic arm or manual welding will leave welds in the welding process. After welding, the weld needs to be manually polished to make the weld surface smooth and consistent with the outer wall of the strut. However, by manually polishing the weld, the roundness after polishing cannot be guaranteed, which makes the surface of the strut unsightly. At the same time, the current grinding will generate a lot of iron filings and dust, so the working environment of the staff is relatively poor. At the same time, the grinding efficiency is relatively low through manual grinding, which does not meet the current processing efficiency of enterprises. At the same time, traditional mechanical processing needs to gradually transform from manual to intelligent manufacturing, so a device that can realize welding and grinding of struts and tenons is needed.

A welding mechanism 2, a grinding mechanism 3 and a detection mechanism are provided. The welding mechanism 2 and the grinding mechanism 3 are used to weld and grind the connection between the support rod and the tenon in turn, so as to ensure the roundness of the grinding; the rotating clamping mechanism 1 includes a rotating plate 1.1, a rotating shaft 1.2, a swing clamping assembly 1.5, a limit ring 1.8 and a push-out assembly 1.11. Both ends of the rotating shaft 1.2 are installed on the ground through bearings and bearing seats. The rotating shaft 1.2 can rotate. Both ends of the rotating shaft 1.2 are driven by a transmission system driven by a stepper motor 1.3 (the transmission system is a gear transmission system, which is transmitted through two mutually meshing gears to realize the rotation of the rotating shaft 1.2). Two circular rotating plates 1.1 arranged opposite to each other are fixed by bolt fastening, four circular through holes are opened on each rotating plate 1.1, and a rotatable turntable 1.4 is installed in the through hole by bearings, and the turntable 1.4 can rotate relative to the rotating plate 1.1, and multiple turntables 1.4 are distributed in a ring array, and a swing clamping assembly 1.5 is hinged on each turntable 1.4, and a retractable limit ring 1.8 is arranged on the swing clamping assembly 1.5, and the swing clamping assembly 1.5 is clamped on the outer wall of the support rod by the extension and contraction of the limit ring 1.8, and the support rod is clamped in the center by clamping, so that the roundness during welding and the roundness during grinding can be guaranteed. A push-up assembly 1.11 is fixed at the center of the inner side of 1.4 by embedding and bolting, and the push-up assembly 1.11 is used to tighten the two ends of the support rod (that is, the push-up assembly 1.11 pushes outward to limit the two ends of the support rod and tighten the two ends of the support rod), and a motor 1.15 is arranged on the outer side of the rotating plate 1.1, and the output shaft of the motor 1.15 is connected to the center of the disc (the motor 1.15 is fixed to the rotating outer arm by bolts, and meshing gears are fixed on the turntable 1.4 and the output shaft of the motor 1.15 by welding, and the turntable 1.4 is driven to rotate by the motor 1.15, which is convenient for subsequent welding and grinding), so that the rotation of the support rod is realized.

One end of the swing rod 1.6 is hinged on the turntable 1.4, and the other end of the swing rod 1.6 is fixed with a pulley 1.7 through a rotating shaft. When clamping, the pulley 1.7 is pressed on the outer wall of the tenon, so that when the push assembly 1.11 pushes and positions the two ends of the tenon tightly, it can slide, which is convenient for positioning the two ends and contacts the outer wall of the support rod through the pulley 1.7; the limit ring 1. 8 is sleeved on a plurality of swinging rods 1.6, a connecting rod 1.9 is fixed between the limiting ring 1.8 and each swinging rod 1.6 by means of hinge, one end of the connecting rod 1.9 is hinged on the limiting ring 1.8, and the other end of the connecting rod 1.9 is hinged on the swinging rod 1.6, and a plurality of clamping hydraulic cylinders 1.10 for extension and retraction are fixed by means of welding between the turntable 1.4 and the limiting ring 1.8 (the clamping hydraulic cylinder 1.10 is used to realize the left and right movement of the limiting ring 1.8, when the support rod needs to be placed between the two turntables 1.4 , the limit ring 1.8 is moved outward by the clamping hydraulic cylinder 1.10, so that the swing rod 1.6 swings upward to make way for the two ends of the support rod. When the support rod is placed between the two turntables 1.4, the limit ring 1.8 moves inward, so that the swing rod 1.6 swings downward to position and clamp the outer wall of the tenon, thus completing the center clamping of the support rod and the tenon); the ejection assembly 1.11 includes an ejection hydraulic cylinder 1.12 and an ejection plate 1.13, and the ejection hydraulic cylinder 1.12 is fixed at the center of the turntable 1.4 by embedding and welding.

Two welding guns 2.1 are installed on the linkage rod 2.2 and the welding guns 2.1 are in contact with the connection between the support rod and the tenon. The support rod is welded by the welding gun 2.1. When the support rod is clamped, the rotating plate 1.1 rotates 90° to the relative position of the welding gun 2.1 for welding.

[0020] The grinding mechanism 3 is arranged above the two rotating plates 1.1. The grinding mechanism 3 is suspended above by a gantry 3.1 and the two ends of the gantry 3.1 are fixed to the ground by bolts. The grinding mechanism 3 includes a grinding wheel 3.2 driven by a motor 1.15 and a lifting assembly 3.3. The lifting assembly 3.3 is arranged between the grinding wheel 3.2 and the gantry 3.1 (the lifting assembly 3.3 is also a hydraulic cylinder). The lifting of the grinding wheel 3.2 is realized by the lifting assembly 3.3. Two sets of rollers 3.4 are respectively arranged on the left and right sides of the part 3.3 and the rollers 3.4 are located on both sides of the grinding wheel 3.2. The two sets of rollers 3.4 are in contact with the tenon and the outer wall of the support rod respectively (the rollers 3.4 are flush with the bottom surface of the grinding wheel 3.2, so as to ensure that the welding after grinding is flush with the tenon and the outer wall of the support rod). When the support rod is polished, the rotating plate 1.1 rotates 90° for polishing, and the rotation of the support rod is driven by the turntable 1.4 to realize polishing, so that the polishing roundness is relatively high.

[0021] The lifting assembly 4 includes a lifting hydraulic cylinder 4.1 and a lifting arc plate 4.2. A plurality of lifting hydraulic cylinders 4.1 are fixed on the ground below the rotating shaft 1.2 by bolt fastening, and the plurality of lifting hydraulic cylinders 4.1 are arranged side by side horizontally. The piston rod of each lifting hydraulic cylinder 4.1 is vertically upward and a lifting arc plate 4.2 is fixed to the top of the piston rod by bolt fastening. In this way, the combination of the support rod and the tenon welded together is placed on the lifting arc plate 4.2 for lifting and loading. When unloading is required, the lifting arc plate 4.2 is lowered to complete the unloading. When the turntable 1.4 rotates to the bottom, the swing arm 1.6 opens first. When the lifting assembly 4 lifts the support rod between the two turntables 1.4, the swing arm 1.6 is closed and clamped. At the same time, the pushing assembly 1.11 pushes and presses tightly, and the lifting assembly 4 is lowered, thereby completing the clamping of the support rod.
