Description

Technical Field

[0001] The present invention relates to the technical field of workpiece welding equipment, in particular to a lathe workpiece welding equipment. Background Art

[0002] In the field of mechanical processing, lathe workpiece welding is a key technology. There are various welding equipment, including common arc welding equipment, resistance welding equipment, etc. In the context of industrial production, welding can effectively connect different parts for lathe workpieces with complex shapes or requiring special material combinations.

[0003] The patent application with application number CN202020478255.X discloses a lathe workpiece welding device, including a workbench, a roller is provided at the bottom of the workbench, a fixing device is installed on the roller, and a spot welder is provided on the workbench; a working rubber pad is laid flat on one side of the workbench; and it also includes a working power cord and a spot welding gun, one end of the working power cord is connected to the spot welder and the other end is connected to the spot welding gun.

[0004] To sum up, when performing processing and welding operations on thin-walled lathe workpieces, if the clamping force is too large, it is very likely to cause the workpiece to deform. Moreover, if the accuracy of the clamping tool is insufficient or the method of use is improper, the workpiece will easily shift during the welding process, which will lead to deviations in the weld position. This will not only have an adverse effect on the welding quality, but also affect the subsequent processing accuracy, and ultimately affect the yield of the workpiece.

[0005] To this end, we proposed a lathe workpiece welding equipment. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a lathe workpiece welding device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a lathe workpiece welding device, comprising a support mechanism and an auxiliary mechanism, the support mechanism comprising a support frame, the bottom outer wall of the support frame is fixedly connected to a support foot, the outer wall of the support frame is fixedly connected to a first auxiliary motor, the output end of the first auxiliary motor passes through the support frame and is fixedly connected to a first rotating shaft, the outer surface of the first rotating shaft is slidably connected to a first sliding frame, the outer surface of the first sliding frame is fixedly connected to a second auxiliary motor, the output end of the second auxiliary motor passes through the first sliding frame and is fixedly connected to the second rotating shaft, the output end of the second auxiliary motor is provided with a processing mechanism, the inner wall of the support frame is fixedly connected to a first hydraulic rod, and the auxiliary mechanism comprises:

[0008] A connecting frame, wherein the connecting frame is fixedly connected to the first hydraulic rod, and a third hydraulic rod is fixedly connected to the inner wall of the connecting frame on a side away from the first hydraulic rod, and the output end of the third hydraulic rod is fixedly connected to the second fixed block, and the outer surface of the second fixed block is provided with a through hole, and a force-bearing block is provided on the outside of the connecting frame, and the outer surface of the force-bearing block is fixedly connected to the first elastic gasket. The third hydraulic rod can adjust the distance between the force blocks according to the width of the workpiece. At the same time, the first hydraulic rod is used to control the spacing between the connecting frames, so as to achieve clamping of workpieces of different lengths. When the first elastic gasket fixedly connected to the outer surface of the force block contacts the workpiece, the contact area between the first elastic gasket and the workpiece is increased, so that the clamping force can be evenly distributed, reducing the problem of workpiece deformation caused by excessive local pressure.

[0009] According to the above technical solution, the outer wall of the force-bearing block on one side close to the second fixed block is fixedly connected to the second fixed shaft, the end of the second fixed shaft away from the force-bearing block passes through the second fixed frame and is fixedly connected to the second sliding block, the outer wall of the second sliding block close to the force-bearing block is fixedly connected to a spring, and the end of the spring away from the second sliding block is fixedly connected to the second fixed block. When the force-bearing block contacts the workpiece with the help of the first elastic gasket, under the action of the continuous contraction of the third hydraulic rod, the force-bearing block will be squeezed. When the force-bearing block is squeezed, it will push the second sliding block through the second fixed shaft and stretch the spring. In this process, the second fixed shaft can ensure the stability of the force-bearing block during movement, and the spring is used to restore the force-bearing block to its original position after the workpiece is taken out.

When the force-bearing block contacts the workpiece through the first elastic gasket, the force-bearing block will be squeezed due to the continuous contraction of the third hydraulic rod. When the force-bearing block is squeezed, it will use the first rotating rod to push the third sliding block to slide inside the through hole, and the through hole limits the distance of the third sliding block.

When the third sliding block flips the flip frame toward the workpiece with the help of the second rotating rod, the second driving motor is used to adjust the angle of the clamping rod, so that the clamping rod can better fit the shape of the thin-walled workpiece. At the same time, the second elastic gasket can increase the contact area with the workpiece, so that the clamping force is evenly distributed, thereby effectively avoiding deformation problems caused by excessive local pressure.

[0013] According to the above technical solution, the third hydraulic rod simultaneously pulls the second fixed frames on both sides to make the force-bearing blocks contact with the outer surface of the workpiece. After the contact, the force-bearing blocks are squeezed. On the one hand, the second sliding block will be pushed through the second fixed axis and the spring will be stretched, so that the force-bearing blocks are more stable during the movement. On the other hand, the third sliding block will be pushed to slide in the through hole with the help of the first rotating rod, and the flip frame will be driven to flip to one side of the workpiece through the second rotating rod, and then the angle of the clamping rod is adjusted by the second driving motor, so that the clamping rod and the force-bearing blocks cooperate with each other to achieve clamping and fixation of the workpiece. The through hole can limit the sliding distance of the third sliding block, and the second driving motors on both sides respectively drive the clamping rods fixedly connected to their output ends to rotate, so that the workpiece can be clamped in sections, thereby improving the stability of the workpiece being clamped and fixed by the clamping rod and the force-bearing blocks.

[0014] According to the above technical solution, the processing mechanism includes a second sliding frame slidably connected to the second rotating shaft, the inner wall of the second sliding frame is fixedly connected to a second hydraulic rod, the output end of the second hydraulic rod is fixedly connected to a fixed block, the top outer wall of the second sliding frame is fixedly connected to the first fixed frame, the end of the first fixed frame away from the second sliding frame is fixedly connected to the second hydraulic rod, the first fixed frame assists in fixing the top of the second hydraulic rod, so that the second sliding frame tends to be more stable during the movement, the output end of the second auxiliary motor causes the second sliding frame to slide through the second rotating shaft, the number of the second rotating shafts is two, and the two second rotating shafts are used to improve the stability of the second sliding frame during the movement.

[0015] According to the above technical solution, the top outer wall of the fixed block is fixedly connected to the first fixed shaft, the end of the first fixed shaft away from the fixed block passes through the second sliding frame and is fixedly connected to the first sliding block, the inner wall of the first sliding block is slidably connected to the second hydraulic rod, and when the second hydraulic rod pushes the fixed block, with the help of the action of the first fixed shaft, the inner wall of the first sliding block and the outer surface of the second hydraulic rod slide, and this sliding makes the second hydraulic rod more stable in the process of pushing the fixed block.

[0016] According to the above technical solution, the outer surface of the end of the fixed block away from the second hydraulic rod is fixedly connected to the first drive motor, the output end of the first drive motor is fixedly connected to the connecting block, the inner wall of the connecting block is fixedly connected to the dual-axis motor, the output end of the dual-axis motor is rotatably connected to the rotating frame via a rotating shaft, the inner wall of the rotating frame away from the dual-axis motor is fixedly connected to the welding machine, the first drive motor rotates via the rotating shaft, and then drives the connecting block to rotate, the rotation of the connecting block will cause the dual-axis motor and the rotating frame to deflect, the angle of the rotating frame can be adjusted by the dual-axis motor, and the welding machine is used to perform multi-angle welding operations on the workpiece through the dual-axis motor.

[0017] According to the above technical solution, the outer surface of the connecting block is fixedly connected to a limiting rod, and the number of the limiting rods is four. The four limiting rods are symmetrically arranged with the central axis of the connecting block as the center. When the dual-axis motor drives the rotating shaft to flip the rotating frame, the limiting rod will contact the outer wall of the rotating frame. After the limiting rod contacts the outer wall of the rotating frame, the dual-axis motor stops flipping, thereby limiting the flipping angle of the rotating frame and preventing the rotating frame from over-flipping.

[0018] Compared with the prior art, the present invention provides a lathe workpiece welding device with the following beneficial effects:

[0019] 1. The present invention provides a lathe workpiece welding device. When processing and welding thin-walled lathe workpieces, the third hydraulic rod can adjust the distance between the force blocks according to the width of the workpiece. At the same time, the first hydraulic rod can control the spacing between the connecting frames, so that workpieces of different lengths can be clamped, and the auxiliary mechanism can clamp workpieces of different sizes. The clamped and fixed workpiece is then welded by a welding machine, which can avoid the displacement of the workpiece during the welding process, thereby improving the qualified rate of the finished product.

[0020] 2. The present invention provides a supporting mechanism and a processing mechanism. The first auxiliary motor causes the first sliding frame to slide via the first rotating shaft. At the same time, the second auxiliary motor causes the second sliding frame to slide via the second rotating shaft. This enables the welding machine to position the area to be welded on the workpiece, thereby improving the accuracy of the workpiece welding operation.

[0021] 3. The present invention sets a processing mechanism. The first drive motor rotates through the rotating shaft to drive the connecting block to rotate. The rotation of the connecting block causes the dual-axis motor and the rotating frame to deflect. The angle of the rotating frame is adjusted with the help of the dual-axis motor, which enables the welding machine to position the required welding point of the workpiece.

After the contact, the force-bearing blocks are squeezed, and on the one hand, the second fixed shaft pushes the second sliding block and stretches the spring, thereby enhancing the stability of the force-bearing blocks during movement; on the other hand, the first rotating rod pushes the third sliding block to slide in the through hole, and the third sliding block drives the flip frame to flip to one side of the workpiece through the second rotating rod. Then the second driving motor adjusts the angle of the clamping rod, and finally the workpiece is clamped and fixed by the coordinated action of the clamping rod and the force-bearing block. In this process, the through hole can limit the sliding distance of the third sliding block. At the same time, the second driving motors on both sides respectively drive the clamping rods fixedly connected to their output ends to rotate, which can not only clamp the workpiece in sections, but also improve the stability of the workpiece being clamped, prevent the workpiece from being displaced during welding, and thus improve the qualified rate of the finished product.

For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] Example 1: See Figure 1-Figure 2The present invention provides a technical solution: a lathe workpiece welding device, including a support mechanism 1 and an auxiliary mechanism 3, the support mechanism 1 includes a support frame 101, the bottom outer wall of the support frame 101 is fixedly connected to a support leg 102, the outer wall of the support frame 101 is fixedly connected to a first auxiliary motor 103, the output end of the first auxiliary motor 103 passes through the support frame 101, and is fixedly connected to a first rotating shaft 104, the outer surface of the first rotating shaft 104 is slidably connected to a first sliding frame 106, the outer surface of the first sliding frame 106 is fixedly connected to a second auxiliary motor 107, the output end of the second auxiliary motor 107 passes through the first sliding frame 106, and A second rotating shaft 108 is fixedly connected, and a processing mechanism 2 is provided at the output end of the second auxiliary motor 107. The inner wall of the support frame 101 is fixedly connected to a first hydraulic rod 105 and an auxiliary mechanism 3. The first auxiliary motor 103 drives the first rotating shaft 104 at the output end to slide the first sliding frame 106. The second auxiliary motor 107 on the first sliding frame 106 drives the second sliding frame 201 where the processing mechanism 2 is located to slide through the second rotating shaft 108. At the same time, the first hydraulic rod 105 on the inner wall of the support frame 101 works in coordination. In this way, the welding machine 211 can accurately locate the area to be welded on the workpiece, thereby improving the accuracy of the welding operation, including:

[0036] The connecting frame 301 is fixedly connected to the first hydraulic rod 105, and the inner wall of the connecting frame 301 away from the first hydraulic rod 105 is fixedly connected to the third hydraulic rod 302, and the output end of the third hydraulic rod 302 is fixedly connected to the second fixed block 204, and the outer surface of the second fixed block 204 is provided with a through hole 309. A force block 304 is provided on the outside of the connecting frame 301, and the outer surface of the force block 304 is fixedly connected to the first elastic gasket 305. The third hydraulic rod 302 pushes the force block 304 toward one side of the workpiece, and the first hydraulic rod 105 adjusts the distance between the connecting frames 301 on both sides. When the first elastic gasket 305 on the force block 304 contacts the workpiece, the contact area increases, so that the clamping force can be evenly distributed, thereby reducing the problem of deformation of the workpiece due to excessive local pressure.

[0037] When the cam 312 is in the unlock state, the second stop 308 is turned to the unlock position, and the second stop 308 is turned to the unlock position, so that the cam 312 is unlocked and the lock 304 is unlocked.

[0038] The inner wall of the force-bearing block 304 is rotatably connected to the first rotating rod 310 through a rotating shaft, and the outer wall of the first rotating rod 310 at one end away from the force-bearing block 304 is rotatably connected to the third sliding block 311 through a rotating shaft. The inner wall of the third sliding block 311 is slidably connected to the through hole 309. When the force-bearing block 304 contacts the workpiece through the first elastic gasket 305, the force-bearing block 304 will be squeezed due to the continuous contraction of the third hydraulic rod 302. When the force-bearing block 304 is squeezed, it will use the first rotating rod 310 to push the third sliding block 311 to slide inside the through hole 309, and the through hole 309 limits the distance of the third sliding block 311.

[0039] Example 2: Please refer to Figure 3 On the basis of embodiment 1, the present invention provides a technical solution: the processing mechanism 2 includes a second sliding frame 201 slidably connected to the second rotating shaft 108, the inner wall of the second sliding frame 201 is fixedly connected to the second hydraulic rod 202, the output end of the second hydraulic rod 202 is fixedly connected to the fixed block 204, the top outer wall of the second sliding frame 201 is fixedly connected to the first fixed frame 203, the end of the first fixed frame 203 away from the second sliding frame 201 is fixedly connected to the second hydraulic rod 202, and the first fixed frame 203 plays an auxiliary fixing role on the top of the second hydraulic rod 202, which helps the second sliding frame 201 to be more stable during movement. At the same time, the output end of the second auxiliary motor 107 drives the second sliding frame 201 to slide through the second rotating shaft 108. The two second rotating shafts 108 can enhance the stability of the second sliding frame 201 during movement and ensure the smooth operation of the entire equipment.

[0040] The top outer wall of the fixed block 204 is fixedly connected with a first fixed shaft 205, and the end of the first fixed shaft 205 away from the fixed block 204 passes through the second sliding frame 201 and is fixedly connected with a first sliding block 206. The inner wall of the first sliding block 206 is slidably connected with the second hydraulic rod 202. When the second hydraulic rod 202 pushes the fixed block 204, under the action of the first fixed shaft 205, the inner wall of the first sliding block 206 slides on the outer surface of the second hydraulic rod 202. Through this sliding, the second hydraulic rod 202 can be made more stable in the process of pushing the fixed block 204, thereby ensuring the stability and reliability of the entire pushing action.

[0041] The outer surface of the end of the fixed block 204 away from the second hydraulic rod 202 is fixedly connected to the first drive motor 207, the output end of the first drive motor 207 is fixedly connected to the connecting block 208, the inner wall of the connecting block 208 is fixedly connected to the dual-axis motor 209, the output end of the dual-axis motor 209 is rotatably connected to the rotating frame 210 via a rotating shaft, and the inner wall of the rotating frame 210 away from the dual-axis motor 209 is fixedly connected to the welding machine 211. The first drive motor 207 rotates via the rotating shaft, driving the connecting block 208 to rotate. This rotational action causes the dual-axis motor 209 and the rotating frame 210 to deflect. The dual-axis motor 209 can adjust the angle of the rotating frame 210, so that the welding machine 211 can accurately locate the welding point of the workpiece, thereby ensuring that the welding machine 211 performs welding operations on the workpiece from a suitable angle.

[0042] The outer surface of the connecting block 208 is fixedly connected to the limiting rod 212. The limiting rod 212 has a certain toughness to prevent the rotating frame 210 from breaking after contacting the limiting rod 212. There are four limiting rods 212, and the four limiting rods 212 are symmetrically arranged with the central axis of the connecting block 208 as the center. When the dual-axis motor 209 drives the rotating shaft to flip the rotating frame 210, the limiting rod 212 will contact the outer wall of the rotating frame 210. When the limiting rod 212 contacts the rotating frame 210, the dual-axis motor 209 stops working, thereby limiting the flipping angle of the rotating frame 210, avoiding a series of problems that may be caused by excessive flipping of the rotating frame 210, and ensuring the stability of the entire equipment operation and the accuracy of the welding operation.

[0043] Example 3: Please refer to Figure 4-Figure 8When the cam 314 is in the unlock state, the cam 314 is in the unlock state, and the lock 302 is in the unlock state, so that the cam 314 can be unlocked.

[0044] The inner wall of one end of the flip frame 313 away from the second fixed frame 303 is fixedly connected to the second driving motor 314, the output end of the second driving motor 314 is fixedly connected to the clamping rod 315, and the outer surface of the clamping rod 315 away from the second driving motor 314 is fixedly connected to the second elastic gasket 316. When the third sliding block 311 flips the flip frame 313 toward the workpiece side with the help of the second rotating rod 312, the angle of the clamping rod 315 is adjusted by the second driving motor 314, so that the clamping rod 315 can better fit the shape of the thin-walled workpiece. At the same time, the second elastic gasket 316 can increase The large contact area with the workpiece makes the clamping force evenly distributed, thereby effectively avoiding deformation problems caused by excessive local pressure. When the third sliding block 311 flips the flip frame 313 toward the side of the workpiece through the second rotating rod 312, the second drive motor 314 adjusts the angle through the clamping rod 315 fixedly connected to the output end, and contacts the workpiece through the second elastic gasket 316 fixedly connected to the outer surface of the clamping rod 315. When the second elastic gasket 316 is squeezed, the contact area with the workpiece is increased, so that the clamping force is evenly distributed, thereby effectively preventing deformation problems of the workpiece due to excessive local pressure.

[0045] The third hydraulic rod 302 simultaneously pulls the second fixed frames 303 on both sides, so that the force-bearing block 304 contacts the outer surface of the workpiece. After the contact, the force-bearing block 304 is squeezed. On the one hand, it pushes the second sliding block 307 through the second fixed shaft 306 and stretches the spring 308, making the force-bearing block 304 more stable during the movement. On the other hand, it pushes the third sliding block 311 to slide in the through hole 309 with the help of the first rotating rod 310, and drives the flip frame 313 to flip to one side of the workpiece through the second rotating rod 312. Then, the angle of the clamping rod 315 is adjusted by the second driving motor 314, so that the clamping rod 315 and the force-bearing block 304 cooperate with each other to achieve the clamping and fixation of the workpiece. The shaft 306 pushes the second sliding block 307 and stretches the spring 308 to ensure that the force block 304 moves more stably. The first rotating rod 310 pushes the third sliding block 311 to slide in the through hole 309, and the second rotating rod 312 drives the flip frame 313 to flip to the side of the workpiece. Then the second driving motor 314 adjusts the angle of the clamping rod 315. The clamping rod 315 and the force block 304 cooperate with each other to achieve clamping and fixing of the workpiece. The through hole 309 can limit the sliding distance of the third sliding block 311, and the second driving motors 314 on both sides drive the clamping rod 315 to rotate respectively, which can clamp the workpiece in sections, thereby enhancing the stability of the workpiece being clamped and fixed by the clamping rod 315 and the force block 304.
