Description
Technical Field
[0001] The utility model relates to the technical field of box processing, in particular to a box bearing device for a vertical box welding machine. Background Art
[0002] The process of welding the reinforcing ribs to the box to maintain the stability of the box structure is usually carried out using a vertical box welding machine with a bearing mechanism. The bearing mechanism is used to maintain the relative position of the box, so that the distance between the box welding position and the welding electrode head can be kept stable and appropriate. This maintains good welding conditions and ensures good welding quality.
[0003] During the use of the vertical box welding machine, the welding electrode head of the vertical box welding machine is often worn due to reasons such as poor electrode cooling speed, excessive current and poor electrode material. After the welding electrode head of the vertical box welding machine is worn to a certain extent, the height position of the box supported by the bearing mechanism remains unchanged, which will cause the appropriate distance between the welding electrode head and the box welding position to become larger, resulting in poor welding conditions. After the conditions of the welding processing box deteriorate, the quality of the box welding processing will undoubtedly deteriorate, and in severe cases, the welding processing process of the box cannot be carried out normally. Utility Model Content
[0004] The utility model aims to provide a box bearing device for a vertical box welding machine, so as to assist workers to quickly adjust the distance between the box welding position and the welding electrode head.
[0005] In order to solve the above technical problems, the specific solution adopted by the utility model is:
[0006] A box bearing device for a vertical box welding machine comprises two bearing plates whose surfaces are kept flush and a bearing mechanism for driving the two bearing plates to move vertically synchronously and equidistantly;
[0007] The bearing mechanism includes a base, a telescopic rod arranged on the base, an adjusting screw rotatably connected to the base, and a sliding screw block threadedly connected to the adjusting screw. The top end of the telescopic rod is connected to the bearing plate, and the sliding screw block slides in a limiting sliding groove opened in the base. The sliding screw block is rotatably matched with the pushing connecting rod connected to the top end of the telescopic rod. The thread directions at both ends of the adjusting screw are opposite so that the two sliding screw blocks can be installed separately.
[0008] As a further optimization of the box bearing device for a vertical box welding machine of the utility model, the base and the center of the adjusting screw are discontinuous, and two spline shafts fixedly connected to the disconnected surface thereof are provided at the center of the adjusting screw. The two spline shafts are slidably matched with spline sleeves, and the spline sleeves are used to drive the spline shafts to rotate.
[0009] As a further optimization of the box bearing device for the vertical box welding machine of the utility model, the surface of the spline sleeve is provided with wear-resistant protrusions.
[0010] As a further optimization of the box bearing device for the vertical box welding machine of the utility model, the bottom surface of the base is a smooth surface for labor-saving pushing.
[0011] As a further optimization of the box bearing device for the vertical box welding machine of the utility model, the two bearing plates are centrally symmetrical with the center of the adjusting screw as the symmetry point.
[0012] As a further optimization of the box bearing device for the vertical box welding machine of the utility model, a plurality of universal balls are evenly distributed on the top surface of the bearing plate.
[0013] As a further optimization of the box bearing device for a vertical box welding machine of the utility model, a plurality of stabilizing ribs are distributed at the connection between the bearing plate and the telescopic rod.
[0014] As a further optimization of the box bearing device for the vertical box welding machine of the utility model, the pitch of the adjusting screw is 1 to 3 mm.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] The utility model sets the rotation of the adjusting screw included in the bearing mechanism to make the two sliding screw blocks move away from or close to each other by an equal amount synchronously under the restriction of the limiting sliding groove provided on the base. The synchronous and opposite movement of the two sliding screw blocks will make the two pushing connecting rods push the corresponding two telescopic rods to extend and retract vertically by an equal amount, and then push the two bearing plates to change their own height positions synchronously and equally. After the bearing plates move to different height positions, the self-locking cooperation of the adjusting screw and the sliding screw blocks will be used for positioning, and then the height position of the box will be positioned. This will assist the staff to conveniently and accurately adjust the distance between the welding position of the box and the welding electrode head.
[0017] As a further optimization of the utility model, the cooperation of the spline sleeve and the spline shaft will realize the synchronous rotation of the two adjusting screws, and at the same time, the center distance of the center discontinuous adjusting screw can be adjusted. When the center distance of the center discontinuous adjusting screw is adjusted, the center discontinuous base will be cooperated to adjust the distance between the two bearing plates. After the distance between the two bearing plates is adjusted, it can adapt to boxes of different lengths for stable bearing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The utility model comprises a bearing mechanism 1 and two bearing plates 2 connected to the bearing mechanism 1. The bearing mechanism 1 is used to maintain the relative position of the two bearing plates 2 and to push the two bearing plates 2 to move vertically in a synchronous and equal manner. When the two bearing plates 2 move vertically in a synchronous and equal manner, the box 3 placed on the two bearing plates 2 will move with it, so that the distance between the box 3 and the welding electrode head 401 can be conveniently adjusted and controlled.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the two supporting plates 2 are symmetrical in center, and the box body 3 is supported by two supporting points to maintain the stability of the height position of the supporting box body 3. The space between the two supporting plates 2 is convenient for the staff to stand between the two supporting plates 2, and then it is convenient for the staff to contact the bottom surface of the box body 3 at the center and adjust its position. Figure 4 As shown, the upper side surfaces of the two support plates 2 are provided with matrix-arranged universal balls 201. The two sets of universal balls 201 can make the box 3 slide easily on the support plate 2, so that the staff can conveniently and labor-savingly adjust the position of the box 3 on the support plate 2, that is, the staff can move different welding positions of the box 3 to the welding electrode head 401 for welding, thereby assisting the staff to weld the box 3 more efficiently.
[0025] like Figure 1 , Figure 2 and Figure 3As shown, the bearing mechanism 1 includes a base 105, a telescopic rod 106 with a bottom fixed end disposed on the base 105, an adjusting screw 101 rotatably connected to the base 105, and a sliding screw 103 threadedly connected to the adjusting screw 101. The top telescopic end of the telescopic rod 106 is fixedly connected to the bearing plate 2, and the vertical telescopic movement of the telescopic rod 106 is utilized to maintain the vertical stable displacement of the bearing plate 2. A plurality of stabilizing ribs 202 are provided at the connection between the bearing plate 2 and the telescopic end of the telescopic rod 106. The arrangement of the stabilizing ribs 202 can stably maintain the horizontality of the bearing plate 2, thereby maintaining the stability of the bearing box 3 at a corresponding height position, and thus assisting the staff in welding the box 3. The telescopic rod 106 is composed of a transition-matched storage cylinder and a movable column. The transition-matched movable column and the storage cylinder can reduce the radial shaking of the two, and thus enable the movable column to be able to extend and retract along the axial direction of the storage cylinder under the restriction of the storage cylinder. The storage tube is the fixed end of the telescopic rod 106 , and the end of the movable column away from the storage tube is the telescopic end of the telescopic rod 106 , thereby enabling the telescopic rod 106 to achieve the effect of limiting the vertical displacement of the carrying plate 2 .
[0026] The sliding screw 103 slides in the limiting slide groove 104 opened on the base 105. The limiting slide groove 104 and the bottom end of the sliding screw 103 are both dovetail-shaped, thereby maintaining the lateral sliding of the sliding screw 103 and the stability of its sliding. That is, the rotation of the sliding screw 103 is prevented during the lateral displacement of the sliding screw 103, thereby causing the sliding screw 103 to be displaced when the adjusting screw 101 rotates. The two sliding screws 103 and the telescopic ends of the telescopic rod 106 are both rotatably connected to the push link 107. The push link 107 is rotatably connected to the telescopic ends of the telescopic rod 106 through a hinge shaft. The push link 107 can move with the movement of the two sliding screws 103 to cause the telescopic rod 106 to be synchronously and equally extended and retracted, thereby causing the bearing plate 2 to be vertically displaced.
[0027] The thread directions of the two ends of the adjusting screw 101 are opposite, and the opposite threads at the two ends of the adjusting screw 101 are respectively threadedly connected with the two sliding screw blocks 103, so that the two sliding screw blocks 103 can stably move away from or close to each other under the restriction of the limiting slide groove 104. The pitch of the adjusting screw 101 is set to 2mm. Then, when the adjusting screw 101 rotates a corresponding number of times in a single time, the sliding amount of the two sliding screw blocks 103 is relatively small. When the sliding screw block 103 slides, the triangle composed of the push connecting rod 107, the telescopic rod 106 and the distance from the telescopic rod 106 to the sliding screw block 103 will be deformed, and according to the Pythagorean theorem and the unchanged length of the pushing connecting rod 107, it can be known that the elongation of the two telescopic rods 106 is the same and the telescopic amount is also relatively small. Therefore, the amount of vertical movement of the bearing plate 2 as the adjusting screw 101 rotates can be slightly adjusted, and then the slight wear of the welding electrode head 401 can be compensated to keep the distance between the two appropriate, that is, to maintain a high-quality welding processing box 3 environment.
[0028] like Figure 3 As shown, in order to adjust the space size between the two bearing plates 2, the center of the adjusting screw 101 and the base 105 is discontinuous. After adjusting the space between the two bearing plates 2, in order to make the adjusting screw 101 with a discontinuous center be controlled to rotate at the same time, spline shafts 108 are fixed on the broken surface of the adjusting screw 101 with a discontinuous center, and the two spline shafts 108 are slidably matched with the spline sleeve 102, and the spline shafts 108 and the spline sleeve 102 are provided with linear depressions and protrusions at the sliding matching. When the spline sleeve 102 rotates, the linear depressions and protrusions will be used to drive the two spline shafts 108 to rotate, so that the adjusting screw 101 with a discontinuous center can rotate synchronously on the basis of adjustable length, that is, the two sliding screw blocks 103 are stably moved away from or close to each other under the restriction of the limiting slide groove 104.
[0029] In order to facilitate the staff to adjust the space between the two supporting plates 2, the bottom surface of the base 105 is set to be a smooth surface that can be pushed with less effort, and then when the lengths of the boxes 3 are different, the staff can push the two bases 105 to move, thereby achieving the purpose of adjusting the distance between the two bases 105. When the distance between the two bases 105 is adjusted, the distance between the two supporting plates 2 is synchronously adjusted through the two telescopic rods 106, so that it can be used to adapt to boxes 3 of different lengths.
[0030] The spline sleeve 102 is arranged on the upper side of the center of the base 105, so that the staff can use the spline sleeve 102 to control the rotation of the screw 101. The outer side of the spline sleeve 102 is provided with a wear-resistant protrusion, so that when the staff controls the spline sleeve 102, the friction between the spline sleeve 102 and the staff's operating part can be maintained, so that the staff can easily control the spline sleeve 102 to adjust the vertical movement of the load-bearing plate 2, that is, to adjust the vertical height position of the load-bearing plate 2.
[0031] In specific use, the staff can use the wear-resistant protrusions provided on the surface of the spline sleeve 102 to increase the friction force, thereby controlling the rotation of the driving spline shaft 102, and then use the spline shaft 108 and the spline sleeve 102 to realize the rotation of the adjusting screw 101. After the adjusting screw 101 rotates, it will drive the two sliding screws 103 to move synchronously in the opposite direction in the limiting slide groove 104. After that, the sliding screw 103 will make the push connecting rod 107 connected to it rotate to make the two telescopic rods 106 synchronously and equally vertically extend and retract, and then make the two bearing plates 2 with the top surfaces horizontally aligned synchronously and equally vertically displaced. This assists the staff to conveniently and quickly adjust the distance between the welding position of the welding box 3 and the welding electrode head 401.
