Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware processing technology, and in particular to a floating mechanism for welding irregularly shaped hardware parts. Background Technology
[0002] Hardware refers to tools made from metals such as gold, silver, copper, iron, and tin through processing and casting. Since hardware comes in many varieties, and some hardware has unusual shapes due to different usage scenarios, these irregularly shaped hardware need to be fixed to prevent them from shaking during production and welding. This requires the use of floating mechanisms for welding irregularly shaped hardware.
[0003] Chinese patent document CN215469139U discloses a floating mechanism for welding irregularly shaped hardware parts, including a support base plate and an adjustable positioning plate. Vertical support plates are fixedly connected to both sides of the lower part of the support base plate, and fixing grooves are provided on both sides of the upper part of the support base plate. Two T-shaped slide rails are fixedly connected to the upper part of the support base plate, and an installation groove is provided on one side of the T-shaped slide rails on the support base plate. This invention, by setting T-shaped slide rails, installation grooves, lifting screws, and guide columns, can adjust the position of the positioning components to meet the positioning needs of irregularly shaped hardware parts of different sizes. By setting a clamping seat connected to the sliding clamping plate by a ball joint, sufficient freedom of movement of the clamping seat can be ensured. The compression spring provides a floating clamping force for the floating pressure block, which can greatly reduce the gap during welding of irregularly shaped hardware parts and effectively solve the problem of large gaps during welding caused by uneven force during clamping.
[0004] The existing technology has the following problems:
[0005] In actual use, the above-mentioned equipment is used in situations where the outer surface of irregularly shaped parts is complex and the welding position is usually fixed. When replacing multiple identical parts, the floating pressure blocks inside the equipment need to be adapted to the surface of the parts again. Since each floating pressure block can move, it is difficult for the operator to grasp the position and angle of each part after it is fixed. As a result, the operator needs to adjust the welding angle each time they weld, which reduces the efficiency of the equipment in assisting the welding of parts. Utility Model Content
[0006] This invention provides a floating mechanism for welding irregularly shaped hardware parts to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] A floating mechanism for welding irregularly shaped hardware parts includes a table body, a clamping mechanism rotatably connected to the center of the bottom of the table body, and several floating mechanisms movably connected to the top of the clamping mechanism near the left and right sides.
[0009] The clamping mechanism includes a base, the bottom of which is rotatably connected to the top of the table. A servo motor is fixedly connected to the left side of the base near the front and back. A forward and reverse threaded rod is fixedly connected to the output end of the servo motor, and the right side of the forward and reverse threaded rod is rotatably connected to the inside of the base. A fixing plate is threadedly connected to the outer surface of the forward and reverse threaded rod near the left and right sides. A sliding groove is opened on the top of the base near the front and back, and the bottom of the fixing plate is slidably connected to the inside of the sliding groove. Several movable grooves are opened on the inside of the fixing plate. A connecting plate is fixedly connected to the side of the fixing plate that is farther apart.
[0010] The floating mechanism includes a movable block, the outer surface of which is movably connected to the inner side of the movable groove, a floating block fixedly connected to the opposite side of the movable block, a first spring fixedly connected to the side of the movable block that is farther away from the floating block, and the side of the first spring that is farther away from the floating block fixedly connected to the inner side of the connecting plate.
[0011] Preferably, movable plates are slidably connected to the left, right, front, and back positions of the inner cavity of the fixed plate. Second toothed blocks in a linear distribution are fixedly connected to the upper, lower, and middle positions of the opposite surface of the movable plates. Connecting blocks are fixedly connected to the inner side of the movable plates near the upper and lower positions. A first handle is fixedly connected to the side of the connecting block away from the fixed plate. A first toothed block in a linear distribution is fixedly connected to the side of the movable block near the first handle.
[0012] Preferably, fixing blocks are fixedly connected to the front and rear sides of the inner cavity of the fixing plate near the top and bottom, and a second spring is fixedly connected to the opposite side of the fixing blocks.
[0013] Preferably, the inner side of the connecting plate is slidably connected with a plurality of clamping plates, and the side of the clamping plates near the fixed plate overlaps the outer surface of the movable block.
[0014] Preferably, a limiting plate is fixedly connected to the side of the clamping plate that is farther apart, and a second handle is fixedly connected to the side of the limiting plate that is farther apart.
[0015] Preferably, the edges of the opposite faces of the floating block are arc-shaped.
[0016] Preferably, the bottom of the table is fixedly connected to support columns at the four corners, and the opposite sides of the support columns are fixedly connected to reinforcing plates.
[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0018] 1. This utility model provides a floating mechanism for welding irregularly shaped hardware parts. The movement of the fixed plate drives multiple floating blocks to move, thereby making the multiple floating blocks fit against the surface of the part and effectively clamping the part. At this time, the movable plates on both sides of the movable block use the second spring to lock the second tooth block into the first tooth block, thereby restricting the movement of the movable block. When welding multiple identical parts, the need to readjust the position of the floating blocks can be eliminated, thereby improving the efficiency of the equipment-assisted welding.
[0019] 2. This utility model provides a floating mechanism for welding irregularly shaped hardware parts. A servo motor drives a forward and reverse threaded rod to rotate, thereby moving the fixed plate and effectively clamping and fixing the connection at the top of the base. This prevents parts from falling off during subsequent welding processes, thereby improving the welding effect of the equipment on the parts. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] like Figures 1 to 5 As shown, a floating mechanism for welding irregularly shaped hardware parts includes a table body 1, a clamping mechanism 2 rotatably connected to the middle of the bottom of the table body 1, and several floating mechanisms 3 movably connected to the top of the clamping mechanism 2 near the left and right sides.
[0030] The clamping mechanism 2 includes a base 20, the bottom of which is rotatably connected to the top of the table body 1. A servo motor 21 is fixedly connected to the left side of the base 20 near the front and back. A forward and reverse threaded rod 22 is fixedly connected to the output end of the servo motor 21. The right side of the forward and reverse threaded rod 22 is rotatably connected to the inside of the base 20. A fixing plate 23 is threadedly connected to the outer surface of the forward and reverse threaded rod 22 near the left and right sides. A sliding groove 201 is opened on the top of the base 20 near the front and back. The bottom of the fixing plate 23 is slidably connected to the inside of the sliding groove 201. Several movable grooves 231 are opened on the inside of the fixing plate 23. A connecting plate 232 is fixedly connected to the side of the fixing plate 23 that is farther apart.
[0031] The floating mechanism 3 includes a movable block 30, the outer surface of which is movably connected to the inner side of the movable groove 231. A floating block 31 is fixedly connected to the opposite side of the movable block 30. A first spring 32 is fixedly connected to the side of the movable block 30 that is farther away from the floating block 31. The side of the first spring 32 that is farther away from the floating block 31 is fixedly connected to the inner side of the connecting plate 232.
[0032] Since hardware parts come in various types, and some irregularly shaped hardware parts need to be fixed during production and welding, the irregularly shaped hardware parts are first placed on the top of the base 20, and then the servo motor 21 is powered on, so that the output end of the servo motor 21 drives the forward and reverse threaded rod 22 to rotate. The rotation of the forward and reverse threaded rod 22 drives the fixing plate 23 on the outer surface to move relative to each other. The movement of the fixing plate 23 then drives several fixing blocks 233 on the inner side to move. At this time, the curved side of the floating block 31 is attached to the outer surface of the part. The further movement of the fixing plate 23 drives the floating block 31 and the movable block 30 to move in the movable groove through the elastic force of the first spring 32, so that each floating block 31 and the movable block 30 can extend and retract to the appropriate position according to the contour of the part, so that each floating block 31 is attached to the connected outer surface. Since the floating block 31 and the movable block 30 are movably connected in both fixing plates 23, the clamping mechanism 2 and the floating mechanism 3 can clamp and fix the left and right sides of the part.
[0033] like Figures 4 to 6As shown, movable plates 24 are slidably connected to the inner cavity of fixed plate 23 at the left, right, front, and back positions. Second toothed blocks 241 with linear distribution are fixedly connected to the upper, lower, and middle positions of the opposite side of movable plate 24. Connecting blocks 242 are fixedly connected to the inner side of movable plate 24 near the upper and lower positions. A first handle 243 is fixedly connected to the side of connecting block 242 away from fixed plate 23. First toothed blocks 33 with linear distribution are fixedly connected to the side of movable block 30 near the first handle 243.
[0034] After the floating block 31 and the movable block 30 move to both sides of the part, the first handle 243 is pulled first, causing the first handle 243 to move the connecting block 242 and the movable plate 24. This moves the second toothed block 241 on one side of the movable plate 24 away from the surface of the first toothed block 33. After the floating block 31 and the movable block 30 move to a suitable position and fit against the outer surface of the part, the connecting block 242 and the movable plate 24 move the second toothed block 241 to the surface of the first toothed block 33, thereby restricting the movement of the first toothed block 33. Once the first toothed block 33 is restricted, the movement of the floating block 31 and the movable block 30 is also restricted, thus fixing the floating block 31 and the movable block 30.
[0035] like Figure 6 As shown, fixing blocks 233 are fixedly connected to the front and rear sides of the inner cavity of the fixing plate 23 near the top and bottom, and a second spring 234 is fixedly connected to the opposite side of the fixing blocks 233.
[0036] The connecting block 242 is moved by the elastic force of the second spring 234, and the movement of the connecting block 242 causes the movable plate 24 to move, thereby making the movable plate 24 and the second toothed block 241 on the right side fit against one side of the movable block 30.
[0037] like Figure 7 As shown, several clamping plates 251 are slidably connected to the inner side of the connecting plate 232, and the side of the clamping plate 251 near the fixed plate 23 overlaps the outer surface of the movable block 30.
[0038] When it is necessary to reset the positions of floating block 31 and moving block 30, the moving block 30 is first fixed by the moving contact of connecting block 242 and moving plate 24. Then, the floating block 31 and moving block 30 can be pulled towards connecting plate 232 by the movement of clamping plate 251.
[0039] like Figure 7 As shown, a limiting plate 25 is fixedly connected to the side of the clamping plate 251 that is farther away from the clamping plate 251, and a second handle 252 is fixedly connected to the side of the limiting plate 25 that is farther away from the clamping plate 25.
[0040] Pulling the second handle 252 will move the limit plate 25, which in turn moves the clamping plate 251, which in turn moves several movable blocks 30.
[0041] like Figure 4 and Figure 5 As shown, the edges of the opposite face of the floating block 31 are arc-shaped.
[0042] The arc-shaped floating block 31 can fit against the outer surface of the part, and the arc-shaped floating block 31 can prevent the sharp edges from damaging the part.
[0043] like Figure 1 As shown, support columns 10 are fixedly connected to the four corners of the bottom of the table body 1, and reinforcing plates 11 are fixedly connected to the opposite sides of the support columns 10.
[0044] The support column 10 can support and fix the bottom of the table body 1, and the reinforcing plate 11 can reinforce the support column 10.
[0045] The working principle of this utility model is as follows: Before welding irregularly shaped parts, the parts need to be fixed. First, the parts are placed on the top of the base 20. The forward and reverse threaded rod 22 drives the fixed plate 23 to move. The movement of the fixed plate 23 drives several movable blocks 30 and floating blocks 31 to move, thereby clamping and fixing the parts. At this time, the extension and retraction of the first spring 32 makes the side of the floating block 31 with the arc effectively fit against the outer surface of the parts. The second spring 234 drives the connecting plate 232 to move, so that the second tooth block 241 is engaged with the surface of the first tooth block 33, thereby restricting the movable block 30 and fixing the position of the floating block 31. After the parts are welded and removed, the unwelded parts can be placed in the contour formed by the fixed floating block 31 and fixed and welded again.
[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
