Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a cylinder base welding device. Background Art

[0002] In construction machinery trolleys, the cylinder plays a vital role. As the core actuator of the hydraulic system, it can convert hydraulic energy into mechanical energy. In order to facilitate the installation of the oil cylinder on the engineering machinery trolley, a connecting ring is usually set on the base of the oil cylinder. In the actual production process, since the oil cylinder is usually long, in order to facilitate processing, the connecting ring is usually welded to the base first, and then the base and the oil cylinder are welded. In order to ensure the stable connection between the base and the oil cylinder, a clamping ring is also set on the surface of the base. The clamping ring is located in the oil cylinder and cooperates with the inner wall of the oil cylinder. When welding the base and the oil cylinder, the base and the oil cylinder will be placed in the positioning tooling to align the two and make the clamping ring penetrate into the oil cylinder. This step is usually performed manually, and then the connection between the base and the oil cylinder is spot welded to fix the two together first, and then start to rotate to complete the welding. However, a single tooling can only position one base and oil cylinder, which means that only one oil cylinder can be welded at a time, which is not conducive to improving production efficiency. When the production volume is relatively large, in order to ensure the rapid progress of production, only multiple devices can be used for production, and the oil cylinder needs to be taken manually, which requires multiple people to operate, and the labor cost will also increase significantly.

However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] like Figure 1 to Figure 8 As shown, an embodiment of the present application provides a cylinder base welding device, including: a workbench 100, a supporting mechanism 200, a welding mechanism 300, and a feeding mechanism 400.

[0029] A support frame 101 is provided below the workbench 100. The workbench 100 is provided with a plurality of through holes 102 arranged at intervals along its width direction for passing the oil cylinder. The bearing mechanism 200 includes a mobile frame 201 arranged above the workbench 100 and movable along its length direction, and a lifting frame 202 arranged on the support frame 101 and movable along the vertical direction. The mobile frame 201 is provided with a plurality of bearing columns 203 arranged at intervals along the width direction of the workbench 100 and with the axis arranged horizontally. The bearing columns 203 are arranged around the axis of the through holes 102. The lifting frame 202 is provided with a bearing plate 204 which is movable along the width direction of the workbench 100 and is used to carry the oil cylinder and pass it through the through hole 102 to abut against the base; the welding mechanism 300 is installed on the workbench 100, including a plurality of brackets 301 which are arranged at intervals along the width direction of the workbench 100 and are adjustable in height, and a welding gun 302 which rotates around the axis of the through hole 102 is provided on the bracket 301 and is used to weld the oil cylinder and the base; the feeding machine The structure 400 includes a first material frame 401 and a second material frame 402 respectively arranged at both ends of the support frame 101 in the length direction. The first material frame 401 is arranged to move in the vertical direction, and a plurality of support rods 403 are arranged in a rectangular array on the side. A plurality of bases are placed along the axial direction of the support rod 403. A connecting rod 404 is arranged to move along the length direction and the vertical direction on the workbench 101. A plurality of push blocks 405 are arranged at the bottom of the connecting rod 404 along the length direction thereof, which are used to push the base onto the bearing column 203. The second material frame 401 is arranged to move in the vertical direction, and a plurality of support rods 403 are arranged on the side of the support frame 101. 02 contains a plurality of oil cylinders arranged in a rectangular array, and a plurality of push rods 406 are arranged vertically and spaced apart along the width direction under the support frame 101. The push rods are arranged to move along the length direction and the vertical direction of the support frame 101. When used, the push rods 406 pass through the support frame 101 and the second material frame 402 in sequence, and the upper end is located on the inner side of the oil cylinder, which is used to push the oil cylinder onto the supporting plate 204, and the welding mechanism 300 is located between the second material frame 402 and the movable frame 201 to avoid interference during the transfer of the base.

[0030] Specifically, Figure 1-Figure 2 , Figure 4As shown, a retaining ring 210 is provided on the side wall of the bearing column 203 for abutting against the base so that the central axis of the base and the axis of the through hole 102 are located on the same straight line, and one end of the bearing column 203 is detachably mounted on the connecting frame 205, for example, by threaded connection, so as to facilitate replacement according to different sizes of the base, and a connecting shaft 206 is provided on the top of the connecting frame 205, and the connecting shaft 206 is rotatably mounted on the mobile frame 201, and when performing welding operations, the connecting shaft 206 is coaxially arranged with the through hole 102, and a driven gear 207 is installed on the connecting shaft 206, and a first driving gear 208 is provided between two adjacent driven gears 207, and the first driving gear 208 is meshed with the two adjacent driven gears 207, The first driving gear 208 is installed on the first transmission shaft 209, and the first transmission shaft 209 is rotatably installed on the mobile frame 201, and one of the first transmission shafts 209 is connected to the output end of the first power device, and the first power device is installed on the mobile frame 201. When the oil cylinder and the base need to be welded, the oil cylinder and the base are first spot-welded by the welding gun 302 to connect the two, and then the first power device drives the first transmission shaft 209 to rotate, driving the first driving gear 208 to rotate, thereby rotating the driven gear 207, and the rotation direction of the driven gear 207 is the same. Driven by the driven gear 207, the connecting frame 205 starts to rotate, thereby driving the base to rotate, and then completing the welding operation.

[0031] Specifically, Figure 1-Figure 2 As shown, the movable frame 201 is connected to the movable end of the fourth horizontal linear mechanism, and the fourth horizontal linear mechanism is installed on the workbench 100 and arranged along its length direction. When the supporting base is needed, the suspended end of the supporting column 203 is directed toward the first material frame 401, and the movable frame 201 is driven to move toward the first material frame 401 by the fourth horizontal linear mechanism until the supporting column 203 abuts against the support rod 403, and then the base can be pushed onto the supporting column 203, and then the movable frame 201 can be moved back.

[0032] Specifically, Figure 1-Figure 3 , Figure 6As shown, a detachable limiting plate 211 is provided on the bearing plate 204, for example, a snap connection or a bolt connection is adopted, so as to facilitate the replacement of the bearing plate 204 to adapt to oil cylinders of different sizes. A plurality of limiting portions 212 are provided on the side of the limiting plate 211 along its length direction. The limiting portion 212 is U-shaped, and its opening faces the second material frame 402, and the axis of the arc surface of the limiting portion 212 is on the same straight line as the axis of the through hole 102. When the oil cylinder is located on the bearing plate 204, the oil cylinder is located in the limiting portion 212, and the side surface contacts the bottom of the limiting portion 212, which is used to limit the circumference of the oil cylinder to ensure the contact area with the side surface of the oil cylinder, thereby ensuring the limiting effect. One end of the bearing plate 204 is connected to the moving end of the first horizontal linear mechanism, and the first horizontal linear mechanism is installed on the lifting frame 202. The lifting frame 202 is connected to the moving end of the first vertical lifting mechanism, and the first vertical lifting mechanism is installed on the support frame 101. When it is necessary to weld the oil cylinder and the base, The lifting frame 202 is driven to move upward by the first vertical lifting mechanism, and the supporting plate 204 also moves upward synchronously, so that the oil cylinder passes through the through hole 102 and abuts against the base. After welding is completed, the suspended end of the supporting column 203 is directed toward the welding mechanism 300, and then the supporting column 203 can be pulled out from the connecting ring of the base. Under the action of the limiting portion 212, the oil cylinder after welding can be prevented from moving with the supporting column, and in the welding process, the push rod 406 always keeps in contact with the inner wall of the oil cylinder, so as to ensure the limitation of the oil cylinder during the process of pulling out the supporting column 203 to prevent the oil cylinder from tipping over. Then, the lifting frame 202 is moved downward so that the oil cylinder after welding is lower than the bottom surface of the workbench 100 as a whole, and then the push rod 406 is moved downward so that its top end is lower than the bottom surface of the supporting plate 204. Then, the supporting plate 204 is driven to move by the first horizontal linear mechanism so that the supporting plate 204 is located outside the support frame 101, so as to facilitate the removal of the oil cylinder after welding.

[0033] Specifically, Figure 1 , Figure 4As shown, a first screw 303 is provided at the bottom of the bracket 301, and the first screw 303 is passed through the mounting frame 304 and locked with a nut, so that the height of the bracket 301 can be adjusted in time according to the size of the oil cylinder and the base, so as to ensure that the welding gun 302 can weld the connection between the oil cylinder and the base, and the mounting frame 304 is installed on the bottom plate 311, and the bottom plate 311 is slidably matched on the workbench 100 and is moved along its length direction. For example, the bottom plate 311 is connected to the moving end of a horizontal linear mechanism, and the horizontal linear mechanism is arranged along the length direction of the workbench 100. By moving the bottom plate 311, the end of the welding gun 302 can be adjusted to The distance between the axes of the through hole 102 is to adapt to cylinders and bases of different sizes. An arc groove 305 is provided on the bracket 301. A slider 306 is slidably matched in the arc groove 305. The welding gun 302 is installed on the slider 306. When welding, the slider 306 is moved along the arc groove 305 to initially weld the cylinder and the base. The length of the initial welding is longer than that of spot welding, which reduces the desoldering between the base and the cylinder, so that the two can be stably fixed together. The welding gun 302 is moved along its own axial direction, such as by a threaded connection, to further increase the adjustable range of the position of the welding gun 302 and adapt to a wider range.

[0034] Specifically, Figure 1-Figure 2 , Figure 4As shown, a through rod 307 is provided at the bottom of the slider 306, and the through rod 307 is inserted in the arc plate 308. The arc plate 308 is coaxially arranged with the through hole 102 and is rotatably mounted on the mounting frame 304. A tooth portion is provided on the outer wall of the arc plate 308, and the tooth portion is meshed with a second driving gear 309. The second driving gear 309 is mounted on a second transmission shaft 310, and the second transmission shaft 310 is rotatably mounted on the mounting frame 304. Belt transmission is adopted between two adjacent second transmission shafts 310, one of which is connected to the output end of the second power device, and the second power device is mounted on the mounting frame 304. The belt transmission can make the second driving gear 309 rotate in the same direction, thereby ensuring that the rotation direction of the welding gun 302 is also the same, so as to adapt to the rotation direction of the bearing column 203. When welding the oil cylinder and the base, the second transmission shaft 310 is driven to rotate by the second power device. Under the drive of the belt, the second driving gear 309 will start to rotate in the same direction, thereby driving the arc plate 308 to rotate around the axis of the through hole 102. At this time, the slider 306 will move along the arc groove 305, and the welding gun 302 can weld the oil cylinder and the base. After the slider 306 moves to the end of the arc groove 305, the second transmission shaft 310 stops rotating, and the oil cylinder starts to rotate to complete the subsequent welding operation. The rotation angle of the oil cylinder is 360 degrees minus the rotation angle of the slider 306. After welding is completed, the welding gun 302 is turned off to make the oil cylinder continue to rotate, so that the suspended end of the supporting column 203 faces the first material frame 401 to facilitate subsequent operations.

[0035] Specifically, Figure 1-Figure 2 , Figure 7 As shown, both ends of the connecting rod 404 are sleeved on the vertical rod 408, the vertical rod 408 is installed on the moving block 409, the moving block 409 is connected to the moving end of the second horizontal linear mechanism, the second horizontal linear mechanism is installed on the workbench 100, two retaining rings 410 are provided on the vertical rod 408, the connecting rod 404 is located between the two retaining rings 410, and a first spring 411 is sleeved on the vertical rod 408. The two ends of the first spring 411 are respectively abutted against the connecting rod 404 and the retaining ring 410 located above, and are always in a compressed state. When the base needs to be transferred, the moving block 409 is driven toward the first horizontal linear mechanism through the second horizontal linear mechanism. The outer end of the material frame 401 moves and drives the connecting rod 404 to move synchronously. During the movement, the push block 405 will contact the edge of the connecting ring on the base. In order to enable the push block 405 to pass through the push block, the side of the push block 405 away from the center of the workbench 100 is set to an arc surface. When the arc surface contacts the connecting ring, the push block 405 will move upward, and the first spring 411 will be further compressed. After the push block 405 passes the base, the push block 405 will move downward again under the action of the first spring 411. The test is to move the connecting rod 404 back to transfer the base from the support rod 403 to the bearing column 203.

[0036] Specifically, Figure 5 , Figure 8 As shown, the second material frame 402 is opened at one end facing the center of the workbench 100, and a plurality of clamps 412 are provided at the bottom of the second material frame 402 along the width direction of the support frame 101. The clamps 412 are arranged in groups of two, and the oil cylinders are respectively located between the two clamps 412 in a group of two. One end of the clamp 412 passes through the second material frame 402 and is sleeved on the second screw 413. The second screw 413 is rotatably installed on the second material frame 402. The threads of the second screw 413 are divided into multiple groups, and each group of threads is divided into two sections. The rotation directions of the two sections of threads are opposite. The two clamps 412 in a group of two are respectively sleeved on the two sections of threads with opposite rotation directions. The spacing between the two clamps 412 in a group of two can be adjusted by rotating the second screw 413 to adapt to cylinders of different diameters.

[0037] Specifically, Figure 8-Figure 9 As shown, a pressure plate 414 is provided on the top of the second material frame 402, and slide grooves 415 are provided on both sides of the second material frame 402. The pressure plate 414 passes through the slide grooves 415 on both sides, and is provided with side frames 416. The side frames 416 are sleeved on the guide rod 417, and both ends of the guide rod 417 are installed on the protrusions 418. The protrusions 418 are installed on the side of the second material frame 402. A second spring 419 is sleeved on the guide rod 417, and both ends of the second spring 419 are respectively abutted against the side frame 416 and the protrusion 418 located above, and are always in a compressed state. Under the action of the second spring 419, the pressure plate 414 always has a tendency to move downward, thereby applying a force to the end of the cylinder, thereby providing a limit for the cylinder to prevent it from tipping over.

[0038] Specifically, Figure 8 As shown, a baffle 420 is provided at the bottom of the pressure plate 414, and the upper end of the baffle 420 is sleeved on the third screw 421 and locked with a nut. The third screw 421 is installed on the top of the pressure plate 414. When in use, the position of the baffle 420 can be adjusted by turning the nut, thereby limiting the oil cylinder closest to the opening of the second material frame 402 to further prevent the oil cylinder from tipping over.

[0039] Specifically, Figure 5 , Fig. 9As shown, a block 103 is provided under the workbench 100, and an opening is provided at one end of the block 103 away from the center of the workbench 100. The block 103 is connected to an inverted U-shaped frame 104, and the U-shaped frame 104 is connected to the moving end of the second vertical lifting mechanism. The second vertical lifting mechanism is installed on the workbench 100. When the second material frame 402 is placed on the support frame 101, the opening at the end of the block 103 cooperates with the guide rod 417, and the block 103 is located between the side frame 416 and the protrusion 418. When the U-shaped frame 104 is driven to move upward by the second vertical lifting mechanism, the block 103 will lift the side frame 416, so that the baffle 420 releases the limit on the side of the cylinder, so as to facilitate the transfer of the cylinder.
