Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a standard-section single-limb spot welding tool. Background Art

[0002] The standard section mainly includes single limb, horizontal web member, diagonal web member, connecting plate and other structures. The single limb is also called main limb, or single limb angle steel or main limb angle steel, which is composed of two mutually perpendicular steel plates.

[0003] The upper and lower ends of the main limb angle steel of the tower crane standard section are welded with sleeves to connect and fix with the adjacent standard section. The existing method of welding sleeves is relatively cumbersome. First, the welding point must be marked on the main limb angle steel, and then a single sleeve must be matched with the main limb, and then welded. This method of measurement and positioning takes a lot of time, has low processing efficiency, and may also cause measurement errors due to human factors. The product quality cannot be guaranteed and the rework rate is high. Utility Model Content

[0004] The utility model aims at the deficiencies in the prior art and provides a standard-section single-limb spot welding tool.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] The effect of adopting the above technical scheme is: when it is necessary to weld the sleeve and the single-leg angle steel, the operator places the single-leg angle steel on the support frame, supports the single-leg angle steel through the support frame, and then makes the sleeve steel on the support part, supports the sleeve with the support part, and then drives the limiting mechanism. After the limiting mechanism is started, the position of the sleeve can be fixed, that is, the sleeve is limited, and the two sleeves are respectively on both sides of the single-leg angle steel (the outside of two mutually perpendicular steel plates), and then the operator welds the sleeve and the single-leg angle steel.

A V-shaped support block is provided between the two connecting rods for adapting to the single-leg angle steel.

[0009] The effect of adopting the above technical solution is: in the process of welding single-leg angle steel and sleeve, the operator drives the rotating disk to rotate, and the rotation of the rotating disk can drive the entire support frame to rotate, so that the operator can weld different positions of the sleeve and the single-leg angle steel, and the operation is convenient. At the same time, the setting of the two support wheels makes the rotation of the rotating disk more labor-saving.

[0010] Furthermore, a groove is formed at the bottom end of the V-shaped support block.

[0011] The effect of adopting the above technical solution is that when the widths of the two steel plates of the single-leg angle steel are different, the setting of the groove provides redundancy for the connection between the two steel plates of the single-leg angle steel to adapt to different single-leg angle steels.

[0012] Furthermore, each of the support parts includes a support plate located at the end of the connecting rod, the support plate is perpendicular to the connecting rod, the sleeve is placed above the support plate, and the support plate is used to roughly position the sleeve.

[0013] Furthermore, a baffle is provided above the support plate for roughly positioning the sleeve and preventing the sleeve from rotating.

[0014] The effect of adopting the above technical solution is: the operator places the sleeve on the support plate, and the sleeve can be supported by the support plate. At the same time, the baffle is in contact with the sleeve to prevent the sleeve from rotating, thereby improving the accuracy and stability during welding.

[0015] Furthermore, a plurality of V-shaped support blocks are provided, and the V-shaped support blocks at both ends of the connecting rod are provided as a first V-shaped support block and a second V-shaped support block.

[0016] The effect of adopting the above technical solution is: multiple V-shaped support blocks support the single-leg angle steel, further improving the support stability.

Two positioning shafts are provided, and the two positioning shafts are connected by a swing connecting rod, and the swing connecting rod is hinged to the positioning shaft, and both ends of the swing connecting rod are fixedly connected to the side of the first V-shaped support block through a fixing plate.

[0018] The effect of adopting the above technical solution is: after the sleeve is placed on the support plate, the operator drives the positioning shaft to slide, and the sliding of the positioning shaft makes one end of the positioning shaft abut against one end of the sleeve, and pushes the sleeve to move toward the end close to the rotating disk, so that the other end of the sleeve abuts against the side of the rotating disk, that is, the positioning shaft and the rotating disk squeeze the sleeve, thereby achieving the purpose of fixing the position of the sleeve.

[0019] Furthermore, the base is provided with a driving mechanism for driving the positioning shaft to slide.

[0020] Furthermore, the driving mechanism is a cylinder, the piston rod of the cylinder is fixedly connected to a push plate, the push plate is fixedly connected to a limiting shaft, and the limiting shaft is used to precisely position one end of the sleeve.

[0032] When it is necessary to weld the sleeve 100 with the single-leg angle steel, the operator places the single-leg angle steel on the support frame, supports the single-leg angle steel through the support frame, and then places the sleeve 100 on the support part, supports the sleeve 100 with the support part, and then drives the limiting mechanism. After the limiting mechanism is started, the position of the sleeve 100 can be fixed, that is, the sleeve 100 is limited, and the two sleeves 100 are respectively on both sides of the single-leg angle steel (the outside of two mutually perpendicular steel plates), and then the operator welds the sleeve 100 and the single-leg angle steel. The operation is convenient, and there is basically no error in manual positioning, and the quality of the product after welding can be guaranteed.

[0033] The two ends of the base 1 are respectively provided with rotating disks 3, namely the left rotating disk 3 and the right rotating disk 3. Support wheels 4 located below the rotating disk 3 are provided on both sides of the end of the base 1. Two support wheels 4 are provided, and there is a spacing between the two support wheels 4, which is smaller than the diameter of the rotating disk 3. The rotating disk 3 is located between the two support wheels 4, that is, the rotating disk 3 is supported by the two support wheels 4. The provision of the two support wheels 4 makes the rotation of the rotating disk 3 more labor-saving.

[0034] In the embodiment of the utility model, the support frame is a connecting rod 5, the rotating shaft of the rotating disk 3 is horizontally arranged, and the two rotating disks 3 are connected by the connecting rod 5. When the operator rotates the rotating disk 3, the connecting rod 5 can be driven to rotate synchronously, that is, the entire support frame can be rotated, so that the operator can weld different positions of the sleeve 100 and the single-leg angle steel, and the operation is convenient; the connecting rod 5 is provided with two, the two connecting rods 5 are in the same plane, and the two connecting rods 5 are parallel, and there is a spacing between the two connecting rods 5, so as to place the single-leg angle steel, and a V-shaped support block 6 is provided between the two connecting rods 5 for adapting to the single-leg angle steel, and a plurality of V-shaped support blocks 6 are arranged at equal or unequal intervals along the length direction of the connecting rod 5, and the single-leg angle steel can be supported by the V-shaped support block 6.

[0035] The bottom end of the V-shaped support block 6 is provided with a groove 19. Figure 4 As shown, when the widths of the two steel plates of the single-leg angle steel are different, the arrangement of the groove 19 provides redundancy for the connection of the two steel plates of the single-leg angle steel to adapt to different single-leg angle steels.

[0036] The support part includes support plates 9 located at both ends of the connecting rod 5. The support plates 9 are V-shaped. In the initial state (when the rotating disk 3 is not rotated), the support plates 9 are located below the connecting rod 5 and welded below the connecting rod 5, that is, the two ends of the support plate 9 are respectively welded below the two connecting rods 5. The support plate 9 is perpendicular to the connecting rod 5, and the sleeve 100 is placed above the support plate 9. A stop bar 10 is arranged above the support plate 9. Two stop bars 10 are arranged. When the sleeve 100 is placed on the support plate 9, one side of each sleeve 100 is against a stop bar 10. Since one side of the sleeve 100 is a plane, Figure 5 As shown, it is only necessary to limit the arc side of the sleeve 100, and the sleeve 100 can be prevented from rotating by the blocking bar 10, thereby improving the precision and stability during welding. Among them, the plane side of the sleeve 100 is welded to the single-leg angle steel.

[0037] For the convenience of description, the V-shaped support blocks 6 at both ends of the connecting rod 5 are respectively set as the first V-shaped support block 7 and the second V-shaped support block 8. Among them, the main purpose of the V-shaped support block 6 between the two connecting rods 5 is to support a single limb with a shorter size, to support the embedded legs, and to facilitate the welding of the embedded legs. The embodiment of the utility model will not be specifically described for the embedded legs.

[0038] The first V-shaped support block 7 and the second V-shaped support block 8 have the same structure, and the first V-shaped support block 7 is taken as an example for description.

[0039] The limiting mechanism includes a positioning shaft 11 arranged on the first V-shaped support block 7, and the positioning shaft 11 is slidably connected to the first V-shaped support block 7, that is, the two positioning shafts 11 pass through the two sides of the first V-shaped support block 7 respectively, and one end of the sleeve 100 can be abutted by the sliding of the positioning shaft 11, and the other end of the sleeve 100 abuts on the rotating disk 3. The ends of the two positioning shafts 11 away from the rotating disk 3 are connected by a swing link 12, and the swing link 12 is located below the positioning shaft 11. The swing link 12 is hinged to the positioning shaft 11, and the two ends of the swing link 12 are fixedly connected to the side of the first V-shaped support block 7 through a fixing plate 13. When the sleeve 100 is placed on the support plate 9, the operator drives the positioning shaft 11 to slide. The sliding of the positioning shaft 11 makes one end of the positioning shaft 11 abut against one end of the sleeve 100, and pushes the sleeve 100 to move toward the end close to the rotating disk 3, so that the other end of the sleeve 100 abuts against the side of the rotating disk 3, that is, the positioning shaft 11 and the rotating disk 3 squeeze the sleeve 100, thereby achieving the purpose of fixing the position of the sleeve 100.

[0040] A guide block 14 is provided at one end of the positioning shaft 11 close to the rotating disk 3. The diameter of the guide block 14 is smaller than the diameter of the connecting shaft 11. A through hole is opened in the axial direction of the sleeve 100. The outer diameter of the guide block 14 is less than or equal to the inner diameter of the through hole, so that when the positioning shaft 11 slides toward the end close to the rotating disk 3, the guide block 14 can pass into the through hole, and then the sleeve 100 is abutted against the side of the rotating disk 3 by the continued sliding of the positioning shaft 11, thereby fixing the position of the sleeve 100.

[0041] The base 1 is provided with a driving mechanism for driving the positioning shaft 11 to slide. In the embodiment of the utility model, the driving mechanism adopts a cylinder 15, and the piston rod of the cylinder 15 is hinged to the swing link 12. After the cylinder 15 is started, the piston rod of the cylinder 15 slides, which can drive the two positioning shafts 11 to slide in the opposite direction of the piston rod of the cylinder 15, that is, the positioning shaft 11 slides toward the end close to the rotating disk 3, so as to limit the sleeve 100.

[0042] It should be noted that: in the present embodiment, a push plate 17 is connected to the piston rod of the cylinder 15, and the push plate 17 is located on the side of the rotating disk 3 away from the positioning shaft 11, that is, the rear side of the rotating disk 3, and oppositely, it is set to the front side of the rotating disk 3. Two limit shafts 18 are provided on the push plate 17. After the cylinder 15 is started, the piston rod of the cylinder 15 slides, driving the push plate 17 to slide, and the push plate 17 drives the two limit shafts 18 to slide. The limit shaft 18 passes through the rotating disk 3, and the limit shaft 18 is slidably connected to the rotating disk 3. The end of the limit shaft 18 slides to the front side of the rotating disk 3, and the end of the limit shaft 18 is inserted into the through hole of the sleeve 100 to guide the movement of the sleeve 100. Among them, the structure of the limiting shaft 18 is the same as that of the positioning shaft 11. Through the joint action of the limiting shaft 8 and the positioning shaft 11, the purpose of center positioning of the sleeve 100 can be achieved, and the diameters of the positioning shaft 11 and the guide block 14 are different, so that the end face of the positioning shaft 11 is against the end face of the sleeve 100.

[0043] It should be further explained that: in this embodiment, the lengths of the push rods 17 on the left and right sides are different, the length of the push rod 17 on the right side is smaller than the length of the push rod 17 on the left side, and there is a gap during disassembly to improve the convenience during disassembly.

[0044] In the embodiment of the utility model, a reinforcing plate 16 is provided on one side of the rotating disk 3 close to the first V-shaped support block 7 . When the sleeve 100 repeatedly abuts against the rotating disk 3 , the reinforcing plate 16 can improve the strength.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
