Description

Technical Field

[0001] This utility model is used in the fields of mechanical welding and machining, specifically relating to a welding support and locking device for annular splicing casing. Background Technology

[0002] Currently, most ring-shaped workpieces are supported and locked by welding using cylindrical pads and pressed with long strip pressure plates. The pads need to be positioned first, the ring-shaped workpiece is hoisted onto the pads, and then pressed with the pressure plate. Operators need to level the ring-shaped workpiece multiple times. This leveling process not only takes a lot of time, but also poses a risk of bumping or knocking the workpiece.

[0034] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] Please refer to Figures 1-7 This utility model provides an embodiment of a welding support and locking device for annular splicing casing, including annular workpiece 1, worktable 2, support device, locking device 8 and bolts 10. The support device includes a first leveling block 3, a T-nut 4, a connecting screw 5, a support plate 6, a second leveling block 7 and a third leveling block 9. The locking device 8 includes a bracket 81, a baffle 82, a locking block 83, a locking pad 84, a stop 85, a locking screw 86 and a base plate 87.

[0036] The first leveling block 3 is installed on the workbench 2 and connected to the T-nut 4 by connecting screws 5. The T-nut 4 is installed into the T-slot of the workbench 2, and the connecting screws 5 are tightened to fix the first leveling block 3 to the workbench 2. The material grade, surface quality and quantity of the first leveling block 3 can be reasonably selected according to the weight, material and locking performance requirements of the supported parts. When multiple support and locking devices support the same annular workpiece 1, the height of the first leveling block 3 must be consistent. Preferably, the weight of the annular workpiece 1 is about 2.5T, and 6 sets of support and locking devices are used. The height of each first leveling block 3 is 300±0.05mm, and the material is Q345B.

[0037] Two support plates 6 are connected to the upper sides of the first leveling block 3. The second leveling block 7 is connected above the support plates 6. A third leveling block 9 is provided between the support plates 6 at the end away from the slot 72 to support the second leveling block 7 and prevent the second leveling block 7 from deforming due to excessive weight of the ring workpiece 1.

[0038] The second contour block 7 has a bolt hole in the middle and a slot 72 at the rear. The slot 72 mates with the bracket 81. The bracket 81 is connected to the baffle 82 at the rear. The baffle 82 has a locking screw 86. The baffle 82 includes a first baffle 821 and a second baffle 822, which are fixedly connected. A through hole 823 is provided in the middle of the mating position of the first baffle 821 and the second baffle 822. The locking screw 86 passes through the through hole 823 and is screwed into the locking block 83. The locking block 83 includes a first end face 831 and a second end face 832. The height of the first end face 831 is greater than that of the second end face 832. The second end face 832 is close to the baffle 82. The second end face 832 is provided with a threaded hole 833. The threaded hole 833 is coaxial with the through hole 823. The locking screw 86 passes through the through hole 823 and the threaded hole 833 in sequence. The main function of the first baffle 821 and the second baffle 822 is to support the locking screw 86 and restrict the movement of the locking screw 86 during welding of the annular workpiece 1.

[0039] The lower surface of the locking block 83 is set as an inclined surface with an angle of 75°-85°. The inclined surface facilitates the tightening of the locking screw 86 and prevents the support locking device from loosening. The lower surface of the locking block 83 slides with the upper surface of the locking pad 84. The roughness of the mating surface is better than Ra3.2, which reduces the friction of the mating surface.

[0040] The locking pad 84 includes a third end face 841 and a fourth end face 842. The height of the third end face 841 is greater than that of the fourth end face 842. The third end face 841 and the fourth end face 842 are respectively attached to the stop block 85. The stop block 85 includes a first stop block 851 and a second stop block 852. The third end face 841 is attached to the other end face of the second stop block 852 away from the second baffle 822. The fourth end face 842 is attached to the end face of the first stop block 851 close to the second stop block 852. The stop block 85 fixes the locking pad 84.

[0041] The lower surface of the stop block 85 is connected to the base plate 87, which is connected to the bracket 81. A first stop block 851 is provided on one side of the upper surface of the base plate 87, and the base plate 87 is fixedly connected to the first stop block 851. A second stop block 852 is provided on the other side of the upper surface of the base plate 87. One end face of the second stop block 852 is in contact with the side of the second stop plate 822 near the bracket 81. The base plate 87 is connected to the bracket 81 by screws to support the locking pad 84.

[0042] A bolt hole is provided in the middle of the second leveling block 7. Bolt holes are also provided in the second leveling block 7, the bracket 81, the locking pad 84, and the base plate 87. The locking block 83 has an oblong bolt hole with the same diameter as the bolt hole in the second leveling block 7. The locking block 83 can move according to the rotation of the locking screw 86. The bolt holes are collinear, and a bolt 10 passes through the bolt hole. The bolt 10 passes through the second leveling block 7, the bracket 81, the locking block 83, the locking pad 84, and the base plate 87 in sequence to connect with the annular workpiece 1 and fix the annular workpiece 1. By rotating the locking screw 86, the locking block 83 moves while the locking pad 84 remains stationary, thereby locking the annular workpiece 1.

[0043] The working steps of this utility model are as follows:

[0044] Step 1: Hoist several sets of support locking devices onto the workbench 2, install T-nuts 4 into the T-slots of the workbench 2, tighten the connecting screws 5, and fix the support locking devices onto the workbench 2 via the first equal-height block 3 connected to the T-nuts 4 by the connecting screws 5;

[0045] Step 2: Hoist the ring-shaped workpiece 1 onto the second level block 7, and lock the ring-shaped workpiece 1 by tightening the bolts 10 connected to it.

[0046] Step 3: The rotational torque force is provided manually, hydraulically, or by electric motor to drive the locking screw 86 to rotate. The locking screw 86 drives the locking block 83 to move, and the force is transmitted to the locking pad 83 and the connecting screw 5 to fix the ring workpiece 1.

[0047] This invention utilizes multiple locking devices working together to tighten the ring-shaped workpiece 1 evenly and apply a consistent torque, thereby achieving the effect of locking the ring-shaped workpiece 1.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
