Description

Technical Field

[0001] The utility model relates to the field of precision parts processing, in particular to a welding device used for precision parts processing. Background Art

[0002] Welding, also known as welding, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Mechanical parts, also known as mechanical elements, are the basic components of machinery and are inseparable individual parts that make up machinery and machines. Some mechanical parts need to be welded together after machining, so relevant welding equipment is needed.

[0003] At present, in the process of welding parts inside precision tubes, it is necessary to use a clamp to clamp and fix the pipe to be welded, and then weld. After welding, workers need to use a hammer to knock on the position of the weld. The purpose is to knock off the welding slag at the weld. At the same time, the knocking process can cause the weld to produce plastic deformation, thereby offsetting part of the shrinkage of the weld, thereby effectively reducing the welding residual stress and avoiding the probability of cracks in the weld. However, the use of manual knocking will result in a higher labor intensity for workers. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0028] See also Figure 1-5 A welding device for precision parts processing includes a rotating mechanism 1, which includes a base 101, a fixed frame 102 is symmetrically fixedly connected to the top of the base 101, and the tops of the two sets of fixed frames 102 are symmetrically rotatably connected to lower rotating rollers 103. The setting of the lower rotating rollers 103 can provide support for the precision pipes to be welded, so that the pipes to be welded can be driven to rotate when the lower rotating rollers 103 rotate. A worm gear 104 is fixedly connected to one end of a set of lower rotating rollers 103, and a worm 106 is meshedly connected to the outer side of the worm gear 104. A stepper motor 105 is fixedly connected to the bottom of one side of the fixed frame 102, and the output end of the stepper motor 105 is fixedly connected to the worm 106. The stepper motor 105 is set to drive the worm 106 and the worm gear 104 to rotate when starting work, thereby driving the corresponding lower rotating roller 103 to rotate.

[0029] The knocking mechanism 3 includes a hexagonal rotating shaft 301 fixedly connected between two groups of lower rotating rollers 103 on one side. The setting of the hexagonal rotating shaft 301 can connect the lower rotating rollers 103 on both sides, so that the lower rotating rollers 103 on both sides can rotate synchronously, and then can drive the precision pipes to be welded on both sides to rotate synchronously. The top four corners of the base 101 are fixedly connected with a first hydraulic rod 107, the output end of the first hydraulic rod 107 is fixedly connected with a cross frame 108, and the bottom four corners of the cross frame 108 are rotatably connected with an upper rotating roller 109. The setting of the first hydraulic rod 107 can drive the cross frame 108 and the upper rotating roller 109 to move downward when starting work, so that the upper rotating roller 109 can limit the pipe to be welded.

[0030] The welding mechanism 2 includes a moving seat 203 symmetrically arranged on the top of the horizontal frame 108. The second hydraulic rod 201 is fixedly passed through the interior of the two groups of moving seats 203. The output ends of the two groups of second hydraulic rods 201 are fixedly connected to the horizontal frame 108. The second hydraulic rod 201 is used to drive the moving seat 203 to move up and down when starting the work. The guide rods 202 are symmetrically slidably connected to the interior of the two groups of moving seats 203. Each group of guide rods 202 is fixedly connected to the horizontal frame 108. The setting of the guide rods 202 can guide the up and down movement of the moving seat 203. The two groups of moving seats 203 are symmetrically fixedly connected with sliding rods 204, and the outer sides of the two groups of sliding rods 204 are slidingly connected with moving frames 205. One side of the moving frame 205 is threadedly connected with a second limiting bolt 208, and the second limiting bolt 208 abuts against the sliding rod 204. The second limiting bolt 208 can limit the moving frame 205 when it is screwed until it is tightly abutted against the sliding rod 204.

[0031] The top of the mobile frame 205 is fixedly connected with a welder 206, and the output end of the welder 206 is fixedly connected with a welding gun 207. The welding gun 207 is fixedly connected to the mobile frame 205. The welder 206 and the welding gun 207 can weld and fix two pipes to be welded when starting work. The outer side of the hexagonal shaft 301 is slidably connected with a cam 302, so that when the hexagonal shaft 301 rotates, the cam 302 can be driven to rotate accordingly. One side of the cam 302 is provided with a sliding seat 303 slidably connected to the base 101, and one side of the mobile frame 205 is symmetrically fixedly connected with an L-shaped slide bar 310, and two groups of L-shaped slide bars 310 are both slidably connected to the sliding seat 303. The setting of the L-shaped slide bar 310 can connect the sliding seat 303 with the mobile frame 205, so that the mobile frame 205 can drive the sliding seat 303 to slide accordingly during the sliding process.

[0032] A vertical plate 312 is symmetrically fixedly connected to one side of the top of the base 101, and a limit guide rod 313 is symmetrically fixedly connected between the two groups of vertical plates 312. Both groups of limit guide rods 313 penetrate the sliding seat 303 and are slidably connected to the sliding seat 303. The setting of the limit guide rod 313 can guide the sliding of the sliding seat 303. Both sides of the cam 302 are rotatably connected with connecting plates 314. One end of the two groups of connecting plates 314 away from the hexagonal rotating shaft 301 is fixedly connected to the sliding seat 303. The connecting plates 314 can connect the cam 302 with the sliding seat 303, so that the sliding seat 303 and the cam 302 can slide synchronously. The bottoms of the two groups of connecting plates 314 are fixedly connected with diagonal braces 311. Both groups of diagonal braces 311 are fixedly connected to the sliding seat 303. The setting of the diagonal braces 311 can further support the connecting plates 314, thereby improving the stability of the connecting plates 314.

[0033] The sliding seat 303 is internally slidably connected with a push rod 304 corresponding to the cam 302, and the end of the push rod 304 away from the cam 302 is fixedly connected with a connecting plate 305, and a spring 306 is fixedly connected between the connecting plate 305 and the sliding seat 303. Specifically, the spring 306 is in a stretched state, so that the elastic action of the spring 306 can pull the connecting plate 305 and the push rod 304 to move toward one side of the cam 302, so that the push rod 304 can be driven to reciprocate when the cam 302 rotates. The push rod 304 is movably connected with a ball 307 on the side close to the cam 302, and the setting of the ball 307 can roll along the outer wall of the cam 302 when the cam 302 rotates, thereby reducing the wear between the push rod 304 and the cam 302.

[0034] The connection plate 305 is detachably connected to a hammer rod 308 inside, and the hammer rod 308 is slidably connected to the sliding seat 303. The setting of the hammer rod 308 can be synchronized with the connection plate 305 and the push rod 304 to reciprocate, so as to continuously strike the weld position to remove the welding slag at the weld and eliminate the stress at the weld. A first limiting bolt 309 is threadedly connected to one side of the connection plate 305, and the first limiting bolt 309 abuts against the connection plate 305. When the first limiting bolt 309 is loosened, the limiting of the hammer rod 308 can be released, so that the hammer rod 308 can slide inside the connection plate 305, so that the hammer rod 308 can meet the needs of striking the welds of tight pipes of different diameters.

[0035] In this embodiment, the welding machine 206 and the welding gun 207 are prior art and will not be described in detail herein.

[0036] When in use, the two precision pipes to be welded are placed on the top of the two groups of lower rotating rollers 103 on both sides, and the welding parts of the two precision pipes to be welded are made to be opposite to each other, and then the first hydraulic rods 107 of each group are started, so that the first hydraulic rods 107 drive the cross frame 108 and each group of upper rotating rollers 109 to move downward, so that each group of upper rotating rollers 109 moves downward to contact the precision pipes to be welded, and then the moving frame 205 is slid, so that the moving frame 205 drives the welding machine 206 and the welding gun 207 to move, until the welding gun 207 is adjusted to be opposite to the parts of the two precision pipes to be welded. When the moving frame 205 slides, the sliding seat 303 can be driven to slide along with it through the L-shaped sliding rod 310. When the sliding seat 303 slides to the point where it can drive the connecting plate 314, the cam 302 and the hammer rod 308 to move along with it, the hammer rod 308 and the cam 302 are adjusted to correspond to the positions of the two precision pipes to be welded, and then the second limiting bolt 208 is screwed to be tightly against the sliding rod 204, so as to limit the moving frame 205, and then the second hydraulic rods 201 on both sides are started, so that the second hydraulic rods 201 drive the moving seat 203, the sliding rod 204 and the moving frame 205 to move along with it. The moving frame 205 moves downward, thereby driving the welding gun 207 to move downward until it contacts the welding parts of the two precision pipes to be welded, and then the welding machine 206 and the stepper motor 105 are started, so that the welding machine 206 can weld the two precision pipes to be welded when starting work, and when the stepper motor 105 starts working, the rotation of the worm 106 and the worm wheel 104 can drive the corresponding two lower rotating rollers 103 and the hexagonal rotating shaft 301 to rotate, and the lower rotating roller 103 can drive the corresponding pipe to be welded to rotate when rotating, so that the welding gun 207 can gradually move the precision pipes to be welded. The hexagonal shaft 301 rotates during the welding process, and the cam 302 can be driven to rotate accordingly. When the cam 302 rotates, the ball 307 can roll along the outer side of the cam 302, thereby cooperating with the spring 306 to push the push rod 304, the connecting plate 305 and the hammer rod 308 to reciprocate, so that the hammer rod 308 continuously knocks the welding part of the precision pipe fitting, thereby knocking off the welding slag that may be attached after welding, and at the same time, it can also promote the plastic deformation of the weld, thereby offsetting a part of the shrinkage of the weld, thereby effectively reducing the welding residual stress and avoiding the probability of cracks in the weld.
