[0013] The specific implementation of the utility model will be described in detail below in combination with the drawings and preferred embodiments.
[0014] As Figure 1 shown, a floor machine counterweight arm welding device, including support 1, fixed bolt 2, panel 3, positioning shaft 4, quick pressure clamp 5 and positioning bolt 6;
[0015] The three horizontal adjusting bolts and the anti-skid base are arranged at the bottom of the support 1 in a triangular distribution, and the horizontal stability of the support can be ensured by rotating the adjusting bolts. The panel is rotatably connected with the support through a deep groove ball bearing, and the bearing seat is fixed by bolts. The flanges 7 at both ends of the panel are rotatably positioned by the fixed pins with interference fit between the flanges and the support, and 4-6 positioning holes are uniformly distributed on the flanges. The positioning shaft is vertically fixed at the center of the panel, and the diameter of the positioning shaft is matched with the inner diameter of the shaft sleeve 7 in an H7 / g6 clearance fit, and a 30°-45° guide chamfer is arranged at the top of the positioning shaft to facilitate the sleeve of the shaft sleeve. The positioning bolts are adjustable structures, and 3-5 positioning bolts are arranged in an array along the through holes at the bottom of the counterweight arm 8, and the heads of the positioning bolts are provided with anti-skid threads to enhance the fixing effect. Two sets of pneumatic quick pressing clamps are used to press the shaft sleeve and the counterweight arm, and the elastic buffer pads are arranged at the contact ends of the pressing plates to prevent damage to the surface of the workpiece. A through groove 10 is formed in the panel, and the width of the through groove is 1 / 3-1 / 2 of the outer diameter of the shaft sleeve, and the depth of the through groove penetrates through the bottom surface of the panel and extends to the edge to form an operating gap of 50-80 mm, so as to facilitate the welding of the shaft sleeve at the bottom.
[0016] During assembly, the horizontal degree of the support is first calibrated by the horizontal adjusting bolts, the positioning shaft and the positioning bolts are installed after the panel is connected with the bearing of the support, the height of the positioning bolts is adjusted and fixed by the locking nuts. When installing the pneumatic pressing clamp, it is necessary to ensure that the pressing plates are uniformly in contact with the workpiece, and the through groove is aligned with the welding area. During use, the fixed pins are loosened, the panel is rotated to the feeding position, the shaft sleeve is sleeved on the positioning shaft, and the counterweight arm is placed, the position is calibrated through the positioning bolts and the scale line of the panel, and then the pressing clamp is started. The panel is rotated to the welding position and locked by the fixed pins, and the welding is completed through the through groove gap. After welding, the workpiece is taken out by loosening the pressing clamp, and the panel is reset to the feeding position for the next cycle.
[0017] The tool kit is arranged on the side of the support to store spare pins and accessories, the cross stiffeners on the back of the panel can enhance the structural rigidity, and the anti-skid base at the bottom ensures the safety of operation.
[0018] It should be noted that, for those skilled in the art, without departing from the principle of the present application, some improvements and refinements can be made, and these improvements and refinements should be regarded as the protection scope of the present application.
