Abstract
Description
Technical Field
[0001] This invention relates to the field of manual welding machine processing, specifically to a manual welding machine for the production and processing of electricity metering boxes. Background Technology
[0002] With the comprehensive advancement of power infrastructure construction and the continuous growth in demand for electricity metering boxes, welding is the core process for forming the box body and assembling the internal support of electricity metering boxes. The quality of the weld directly determines the structural strength, protection level and service life of the metering box.
[0003] Currently, manual welding in the production of electricity metering boxes usually involves operators holding a welding torch, keeping it suspended in the air at a fixed welding angle and torch height. After visually aligning the torch with the weld seam, the operator controls the torch to move at a constant speed along the weld seam to complete the welding. For weld seams of different heights and directions, the operator must adjust their posture and wrist angle to adapt.
[0004] However, during pure handheld manual welding, prolonged operation with the welding torch suspended in the air and the wrist maintaining a fixed posture for extended periods can easily lead to soreness and fatigue, potentially causing misalignment, weld deviation, incomplete welds, uneven weld thickness, and other quality issues. Furthermore, welding accuracy is highly dependent on the operator's experience and condition, resulting in poor quality consistency. In addition, prolonged high-intensity handheld welding can easily cause occupational strain injuries to the operator's wrists, making it difficult to guarantee work safety and health. Summary of the Invention
[0005] The purpose of this invention is to provide a manual welding machine for the production and processing of electricity metering boxes, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a manual welding machine for manufacturing and processing electricity metering boxes, comprising a workbench, a welding machine and a welding torch, wherein a sliding groove is fixedly connected to the top of the workbench, a turning mechanism is provided inside the sliding groove, a fixing mechanism is provided on the top of the turning mechanism, an adjusting mechanism is provided on one side of the fixing mechanism, and an installation mechanism is provided on the top of the adjusting mechanism. The mounting mechanism includes a mounting base and a clamp. The mounting base is located at the bottom of the welding torch, and a clamp is fixedly connected to the top of one side of the mounting base. The clamp can lock the welding torch onto the mounting base. The adjustment mechanism includes a fixed base, a limiting member, a rotating member, and an adjustment plate. The rotating member is fixedly connected to the bottom of the mounting base. The rotating member is movably connected between two sets of limiting members. One end of each set of limiting members is movably connected to the fixed base. The rotating member is movably connected to the adjustment plate. The adjustment plate can drive the limiting members to engage and lock the rotation angle of the rotating member. The fixing mechanism includes a vertically moving column and a movable seat. The movable seat is movably connected to the outer wall of the vertically moving column, and the vertically moving column is slidably connected to the top of the sliding groove. The steering mechanism includes a sliding seat and a rotating rod. The sliding seat is slidably connected inside the sliding groove. The rotating rod is movably connected to the top of the sliding seat, and the top of the rotating rod is fixedly connected to the vertical moving column. The rotation of the rotating rod can drive multiple sets of mechanisms to rotate and adjust the direction of the welding torch.
[0007] Preferably, the adjusting mechanism further includes a connecting rod, a connecting plate, an elastic sheet, and a connecting member. The connecting rod passes through the interior of the two sets of limiting members, and one end of the connecting rod is fixedly connected to a set of limiting members away from the adjusting plate. The outer wall of the rotating component is fixedly connected to the connecting plate, and the connecting plate is fixedly connected to the mounting base. The limiting component and the fixed base are elastically connected by an elastic sheet, and the connecting component is fixedly connected to one side of the fixed base.
[0008] Preferably, the adjusting plate is eccentrically rotatably connected to the end of the connecting rod, and the opposing surfaces of the limiting member and the rotating member are provided with matching engaging teeth. When the adjusting plate is moved to a state perpendicular to the limiting member, the two sets of limiting members will clamp the rotating member to achieve angle locking. When the adjusting plate is released, the elastic sheet can push the limiting member to reset and release the restriction on the rotating member.
[0009] Preferably, the fixing mechanism further includes movable blocks and movable cavities. The two sets of movable seats are L-shaped, the two sets of movable blocks are fixedly connected to the inner side of the movable seats, and the two sets of movable cavities are vertically opened on the outer wall of the vertical moving column. The movable blocks are slidably embedded in the movable cavities.
[0010] Preferably, the fixing mechanism further includes a pressure plate, a positioning pin, a movable groove, and a return spring. The pressure plate is rotatably mounted on the outside of the movable seat, and the end of the pressure plate is provided with a movable groove. The positioning pin is elastically connected to the pressure plate through the movable groove. The return spring is sleeved on the outer wall of the positioning pin, and the positioning pin is elastically connected to the movable seat through the return spring.
[0011] Preferably, multiple sets of positioning holes are evenly and vertically formed inside the movable cavity. When the pressure plate is in the pressed state, it can drive the positioning pin to exit the positioning hole, allowing the movable block to slide inside the movable cavity. When the pressure plate is in the relaxed state, the reset spring can push the positioning pin to insert into the corresponding positioning hole, locking the height position of the movable seat.
[0012] Preferably, the steering mechanism further includes a spring column and a connector. The bottom of the rotating rod is fixedly connected to the connector, and two sets of spring columns are elastically connected to the inner wall of the sliding seat. The side wall of the connector is provided with a slot that matches the spring column.
[0013] Preferably, the bottom of the sliding seat is movably connected to multiple sets of movable balls, the bottom of which contacts the inner bottom surface of the sliding groove, which can reduce the frictional resistance when the sliding seat moves, making the welding torch move more smoothly and steadily.
[0014] Preferably, the installation mechanism further includes a plug-in plate and a support frame. The plug-in plate is fixedly connected to one side of the top of the mounting base and can support the front end of the welding torch. The support frame is fixedly connected to the other side of the top of the mounting base. The clamp is movably installed on the top of the support frame and can tighten the tail end of the welding torch.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention allows the adjusting plate to simultaneously clamp the rotating component via a connecting rod, driven by two sets of limiting components. The angle is rigidly locked by meshing locking teeth. Releasing the adjusting plate releases the limiting components, allowing the operator to quickly adjust and lock the welding angle with one hand. For height adjustment, a press-type pressure plate linked to a positioning pin structure is used. Pressing the pressure plate moves the positioning pin out of the positioning hole, allowing it to slide freely along the movable cavity to adjust the height of the movable seat. Releasing the plate releases the spring, which automatically pushes the positioning pin into the corresponding positioning hole to lock it in place. The installation mechanism uses a front-end plug-in support and a rear-end clamp locking structure, enabling the installation and replacement of different welding torch models. The entire quick-adjustment structure, guide support, and steering switching function form a complete set. It allows for rapid adjustment and adaptation of the welding torch posture and position for different sizes of electricity metering boxes and welding positions, eliminating the need for repeated bolt tightening and alignment calibration. This significantly shortens tooling debugging time and effectively improves the changeover efficiency and operational flexibility of multi-variety, small-batch metering box welding production.
[0016] 2. This invention utilizes an L-shaped sliding groove on the top of the workbench and a sliding seat to provide a regular horizontal guiding path for the welding torch. Multiple sets of movable ball bearings at the bottom of the sliding seat significantly reduce frictional resistance, ensuring smooth and stable movement of the welding torch. Simultaneously, the adjustment mechanism fixes the angle of the welding torch, allowing operators to avoid holding the torch suspended in the air for extended periods. They can simply guide the torch along the groove at a uniform speed to complete continuous welding of straight weld seams, avoiding wrist pain, hand tremors, and positioning errors caused by prolonged handheld welding. The steering mechanism then drives the vertical moving column and welding torch to complete a 90-degree turn. The spring column and the connector's slot automatically and elastically lock in place at two workstations. The fixing mechanism allows free adjustment of the welding torch's working height along the vertical moving column, adapting to the welding needs of metering box supports of different specifications and heights. The multi-dimensional adjustable support structure covers most welding positions on the metering box body, significantly improving the comfort of manual welding operations.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see Figures 1-9 The present invention provides the following technical solution: a manual welding machine for the production and processing of electricity metering boxes, including a workbench 1, a welding machine 2 and a welding gun 3. The internal support of the electricity metering box to be welded is fixed on the top of the workbench 1, and then the welding gun 3 is installed on the mounting mechanism 7. Then the welding machine 2 placed at the bottom of the workbench 1 is powered on. Furthermore, a sliding groove 6 is fixedly connected to the top of the workbench 1. A turning mechanism 8 is provided inside the sliding groove 6. A fixing mechanism 5 is provided on the top of the turning mechanism 8. An adjusting mechanism 4 is provided on one side of the fixing mechanism 5. An installation mechanism 7 is provided on the top of the adjusting mechanism 4. The angle of the installation mechanism 7 can be adjusted by the adjusting mechanism 4, thereby further adjusting the welding angle of the welding torch 3. After adjusting the appropriate angle, the torch tip of the welding torch 3 is aligned with the welding area. Then, the adjusting mechanism 4 is locked to fix the angle of the welding torch 3.
[0021] As one embodiment of the present invention, the mounting mechanism 7 includes a mounting base 70 and a clamp 73. The mounting base 70 is disposed at the bottom of the welding torch 3, and the clamp 73 is fixedly connected to the top of one side of the mounting base 70. The clamp 73 can lock and fix the welding torch 3 on the mounting base 70. Furthermore, the installation mechanism 7 also includes a plug plate 71 and a support frame 72. The plug plate 71 is fixedly connected to one side of the top of the mounting base 70 and can support the front end of the welding torch. The support frame 72 is fixedly connected to the other side of the top of the mounting base 70. The clamp 73 is movably installed on the top of the support frame 72 and can clamp the tail end of the welding torch. The bottom of the welding torch 3 can be inserted into the plug plate 71. The top of the plug plate 71 is provided with an elastic clip to fix one end of the welding torch 3. The other side of the mounting base 70 is equipped with a clamp 73 through the support frame 72. The tail end of the welding torch 3 is inserted into the clamp 73 and the clamp 73 is manually tightened to fix the clamp 73 on the mounting base 70.
[0022] In one embodiment of the present invention, the adjustment mechanism 4 includes a fixed base 40, a limiting member 41, a rotating member 42, and an adjustment plate 44. The rotating member 42 is fixedly connected to the bottom of the mounting base 70. The rotating member 42 is movably connected between two sets of limiting members 41. One end of the two sets of limiting members 41 is movably connected to the fixed base 40. The rotating member 42 is movably connected to the adjustment plate 44. The adjustment plate 44 can drive the limiting members 41 to engage and lock the rotation angle of the rotating member 42. Furthermore, the adjustment mechanism 4 also includes a connecting rod 43, a connecting plate 45, an elastic sheet 46, and a connecting member 47. The connecting rod 43 passes through the interior of the two sets of limiting members 41, and one end of the connecting rod 43 is fixedly connected to a set of limiting members 41 away from the adjustment plate 44. The outer wall of the rotating member 42 is fixedly connected to the connecting plate 45, and the connecting plate 45 is fixedly connected to the mounting base 70. The limiting member 41 and the fixed base 40 are elastically connected through the elastic sheet 46, and the connecting member 47 is fixedly connected to one side of the fixed base 40. Manually move the adjusting plate 44. The connection area between the adjusting plate 44 and the connecting rod 43 is connected by an eccentric rotating shaft. One end of the adjusting plate 44 will press against the surface of the limiting member 41, thereby pulling the connecting rod 43 and causing another set of limiting members 41 to move synchronously. At this time, the two sets of limiting members 41 will move together in the direction of the rotating member 42. Furthermore, the adjusting plate 44 is eccentrically rotatably connected to the end of the connecting rod 43. The opposing surfaces of the limiting member 41 and the rotating member 42 are provided with matching engaging teeth. When the adjusting plate 44 is moved to a state perpendicular to the limiting member 41, the two sets of limiting members 41 will clamp the rotating member 42 to achieve angle locking. When the adjusting plate 44 is released, the elastic piece 46 can push the limiting member 41 to reset and release the restriction on the rotating member 42. Through the mutual engagement of the locking teeth, the two sets of limiting members 41 will be tightly attached to the rotating member 42 and restrict the rotation of the rotating member 42. Therefore, the position of the mounting base 70 will also be restricted synchronously, so that the bracket can be welded in the horizontal direction.
[0023] In one embodiment of the present invention, the fixing mechanism 5 includes a vertical moving column 51 and a movable seat 50. The movable seat 50 is movably connected to the outer wall of the vertical moving column 51, and the vertical moving column 51 is slidably connected to the top of the sliding groove 6. The fixing mechanism 5 also includes a movable block 500 and a movable cavity 510. The two sets of movable seats 50 are L-shaped, the two sets of movable blocks 500 are fixedly connected to the inner side of the movable seat 50, and the two sets of movable cavities 510 are vertically opened on the outer wall of the vertical moving column 51. The movable block 500 is slidably embedded in the interior of the movable cavity 510. When there are no restrictions between the movable seat 50 and the vertical moving column 51, the movable seat 50 can slide inside the movable cavity 510 via the movable block 500, thereby allowing the movable seat 50 to slide up and down on the outer wall of the vertical moving column 51. Furthermore, through the adjusting mechanism 4 and the mounting mechanism 7, the welding torch 3 can move up and down to perform vertical welding on the support. In the example, the fixing mechanism 5 also includes a pressure plate 52, a positioning pin 53, a movable groove 520 and a return spring 54. The pressure plate 52 is rotatably mounted on the outside of the movable seat 50, and the end of the pressure plate 52 is provided with a movable groove 520. The positioning pin 53 is elastically connected to the pressure plate 52 through the movable groove 520. The return spring 54 is sleeved on the outer wall of the positioning pin 53, and the positioning pin 53 is elastically connected to the movable seat 50 through the return spring 54. Furthermore, multiple sets of positioning holes 55 are evenly and vertically opened inside the movable cavity 510. When the pressure plate 52 is in the pressed state, it can drive the positioning pin 53 to exit the positioning hole 55, so that the movable block 500 slides inside the movable cavity 510. When the pressure plate 52 is in the relaxed state, the return spring 54 can push the positioning pin 53 to insert into the corresponding positioning hole 55 and lock the height position of the movable seat 50. If welding is required on a support with a certain height, pressing the pressure plate 52 will compress the return spring 54, leaving the movable seat 50 and the vertical moving column 51 unrestricted. This allows the movable seat 50 to slide on the vertical moving column 51. After releasing the pressure plate 52, the positioning pin 53 returns to its original position under the elastic action of the return spring 54. At the same time, the top of the positioning pin 53 pulls the pressure plate 52 through the movable groove 520. At this time, the bottom of the positioning pin 53 will be inserted into the positioning hole 55, thereby restricting the movable seat 50 on the vertical moving column 51 and determining the position of the welding torch 3. Then, the welding angle of the welding torch 3 can be adjusted by the adjustment mechanism 4, allowing welding of the support with a certain height to be performed.
[0024] As one embodiment of the present invention, the steering mechanism 8 includes a sliding seat 80 and a rotating rod 81. The sliding seat 80 is slidably connected to the inside of the sliding groove 6. The rotating rod 81 is movably connected to the top of the sliding seat 80, and the top of the rotating rod 81 is fixedly connected to the vertical moving column 51. The rotation of the rotating rod 81 can drive multiple sets of mechanisms to rotate and adjust the direction of the welding torch 3. The steering mechanism 8 also includes a spring column 800 and a plug 810. The plug 810 is fixedly connected to the bottom of the rotating rod 81. Two sets of spring columns 800 are elastically connected to the inner wall of the sliding seat 80. The side wall of the plug 810 is provided with a slot adapted to the spring column 800. When the vertical moving column 51 is rotated, the rotating rod 81 will rotate synchronously, so that the connector 810 rotates within the sliding seat 80. The movable space of the connector 810 is only ninety degrees, so the vertical moving column 51 can only rotate ninety degrees. The two sets of connectors 810 correspond to the position of the vertical moving column 51 in the initial state and the position after rotating ninety degrees, respectively. After the vertical moving column 51 rotates, the connector 810 will first squeeze the spring column 800, and then the spring column 800 will be inserted into the hole opened in the side wall of the connector 810 under the elastic action, thereby restricting the rotating rod 81. Both the hole on the side wall of the connector 810 and the end of the spring post 800 are provided with bevels, which allow the vertical moving post 51 to rotate when rotation is required, by applying sufficient force to make the connector 810 overcome the elasticity of the spring post 800 and rotate. Furthermore, the bottom of the sliding seat 80 is movably connected to multiple sets of movable balls 82. The bottom of the movable balls 82 contacts the inner bottom surface of the sliding groove 6, which can reduce the frictional resistance when the sliding seat 80 moves, making the welding torch 3 move more smoothly and steadily. When the welding torch is manually pulled, the sliding seat 80 can slide inside the sliding groove 6 through the multiple sets of movable balls 82 installed at the bottom of the sliding seat 80.
[0025] Working principle: When in use, first fix the internal support of the power metering box to be welded on the top of the workbench 1, then install the welding gun 3 on the mounting mechanism 7, and then turn on the welding machine 2 placed at the bottom of the workbench 1. The bottom of the welding torch 3 can be inserted into the plug plate 71. The top of the plug plate 71 is provided with an elastic clip to fix one end of the welding torch 3. The other side of the mounting base 70 is equipped with a clamp 73 through the support frame 72. The tail end of the welding torch 3 is inserted into the clamp 73. The clamp 73 can be fixedly installed on the mounting base 70 by manually tightening the clamp 73. Then, the angle of the mounting mechanism 7 can be adjusted by adjusting mechanism 4, thereby further adjusting the welding angle of welding gun 3. After adjusting the appropriate angle, the nozzle of welding gun 3 is aligned with the welding area, and then the adjusting mechanism 4 is locked to fix the angle of welding gun 3. The user can manually move the adjustment plate 44. The connection area between the adjustment plate 44 and the connecting rod 43 is connected by an eccentric rotating shaft. When the adjustment plate 44 is moved and made perpendicular to the limiting member 41, one end of the adjustment plate 44 will press against the surface of the limiting member 41, thereby pulling the connecting rod 43. The other end of the connecting rod 43 is fixedly connected to the outer wall of another set of limiting members 41. Therefore, when the connecting rod 43 is pulled, it will move the other set of limiting members 41 synchronously. At this time, the two sets of limiting members 41 will move together in the direction of the rotating member 42. Multiple sets of engaging teeth are provided on the surface of the two sets of limiting members 41 near the rotating member 42. Engaging teeth that cooperate with the limiting members 41 are also provided on both sides of the rotating member 42. Through the mutual cooperation of the engaging teeth, the two sets of limiting members 41 will be tightly attached to the rotating member 42 and restrict the rotation of the rotating member 42. The outer wall of the rotating part 42 is fixedly connected to the mounting base 70 through the connecting plate 45. Therefore, after the rotation of the rotating part 42 is restricted, the position of the mounting base 70 will also be restricted synchronously, so that the bracket can be welded in the horizontal direction. When the angle of the welding torch 3 needs to be readjusted, simply move the adjustment plate 44 again to release the restriction of the limiting member 41. Two sets of elastic plates 46 are set between the two sets of limiting members 41 and the fixed base 40. At this time, under the elastic action of the elastic plates 46, the two sets of limiting members 41 will be lifted up and disengaged from the rotating member 42, so that the mounting mechanism 7 can move. On one side of the fixed seat 40, it is connected to the fixed mechanism 5 via the connector 47. When there is no restriction between the movable seat 50 and the vertical moving column 51, the movable seat 50 can slide inside the movable cavity 510 via the movable block 500, thereby allowing the movable seat 50 to slide up and down on the outer wall of the vertical moving column 51. Then, the welding torch 3 can be moved up and down via the adjustment mechanism 4 and the installation mechanism 7 to perform vertical welding on the bracket. If welding is required on a bracket with a certain height, multiple sets of positioning holes 55 are opened inside the movable cavity 510. At the same time, a pressure plate 52, a positioning pin 53 and a return spring 54 are set on the movable seat 50. When the pressure plate 52 is pressed, the return spring 54 will be squeezed. The movable seat 50 and the vertical moving column 51 are in an unrestricted state, which allows the movable seat 50 to slide on the vertical moving column 51. After the pressure plate 52 is released, the positioning pin 53 is reset under the elastic action of the return spring 54. At the same time, the top of the positioning pin 53 pulls the pressure plate 52 through the movable groove 520. At this time, the bottom of the positioning pin 53 will be inserted into the positioning hole 55, thereby restricting the movable seat 50 on the vertical moving column 51, thus determining the position of the welding gun 3. Then, the welding angle of the welding gun 3 can be adjusted by the adjustment mechanism 4, so that the bracket with a certain height can be welded. In order to facilitate welding on the other side of the metering box bracket in the horizontal direction, the user can rotate the vertical moving column 51, and through the cooperation of the steering mechanism 8, make the entire fixing mechanism 5, the mounting mechanism 7 and the adjusting mechanism 4 rotate together. A rotating rod 81 is fixedly connected to the bottom of the vertical moving column 51. After the vertical moving column 51 is rotated, the rotating rod 81 will rotate synchronously, so that the plug 810 rotates in the sliding seat 80. The movable space of the plug 810 is only ninety degrees, so the vertical moving column 51 can only rotate ninety degrees. Two sets of connectors 810 are provided on the inner wall of the sliding seat 80, corresponding to the position of the vertical moving column 51 in the initial state and the position after rotating ninety degrees. After the vertical moving column 51 rotates, the connectors 810 move within the sliding seat 80 by rotating the rod 81. After rotating 90 degrees, the connector 810 will first squeeze the spring post 800, and then the spring post 800 will be inserted into the hole opened in the side wall of the connector 810 under the action of elasticity, thereby restricting the rotation rod 81. The hole on the side wall of the connector 810 and the end of the spring post 800 are connected by an inclined surface, which allows the vertical moving post 51 to rotate when it needs to be rotated. By applying sufficient force, the connector 810 can break through the elasticity of the spring post 800 and rotate. After the vertical moving column 51 rotates 90 degrees, the angle of the welding gun 3 will also rotate 90 degrees synchronously, so that horizontal welding can be performed on the side of the bracket. When welding the electricity meter box, you can manually hold the welding torch 3 and then manually pull the welding torch. Through the multiple sets of movable balls 82 installed at the bottom of the sliding seat 80, the sliding seat 80 can slide inside the sliding groove 6. The sliding groove 6 is L-shaped. After the welding angle of the welding torch 3 is fixed, the user can pull the welding torch to ensure that the welding path will not deviate. After the angle of the welding torch 3 is fixed, the user can freely apply force to the welding torch without having to maintain the same posture. This avoids the situation where, when using a traditional welding torch, the user needs to maintain the same posture and welding angle after holding the welding torch for a long time, which can cause wrist pain and affect the quality of the welding. It should be emphasized that the sliding block movement principle, clamping principle, snap-fit principle, positioning pin 53 fixing principle, and engagement tooth limiting principle involved in this invention are all existing known technologies. At the same time, the model of welding torch 3, the elastic coefficient of elastic sheet 46 and return spring 54, the size of sliding groove 6 and sliding seat 80, and the size of movable block 500 and movable cavity 510 can all be flexibly adjusted according to actual installation requirements, and will not be described in detail.
