Description

Technical Field

[0001] The utility model relates to the technical field of welding positioning, in particular to a metal part welding positioning tool. Background Art

[0002] Photovoltaic power generation systems convert solar radiation directly into electrical energy, allowing us to harness the sun's energy to generate electricity. Photovoltaic power generation is renewable, clean, and environmentally friendly, playing a significant role in reducing reliance on fossil fuels and greenhouse gas emissions. Laser welding is often used to avoid the impact of traditional welding slag on solar panels.

[0003] Most existing photovoltaic panel metal welding and positioning devices can damage the panels and fail to effectively position the two panels, causing them to shift and misalign during welding, affecting welding accuracy. Furthermore, the fixtures lack flexibility due to the inability to adjust to the shape and thickness of the panels. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a metal parts welding positioning tool.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A metal welding positioning tool comprises a workbench with slots at the four corners, a guide rail welded inside each slot, a slider movably connected to the top of the guide rail, screws connected to the top two sides of the slider via threads, a passive locator and an active locator fixedly connected to the top of the slider, and the passive locator and the active locator forming a group.

[0007] As a further solution of the present invention: grooves are formed on both sides of the interior of the slider, notches are formed on both sides of the top of the groove, and balls are connected in a rolling manner at equal distances in the notches.

[0008] As a further solution of the present invention: clamping blocks are connected to both sides of the guide rail through threads, and limit axes are fixedly connected to both sides of the guide rail.

[0009] As a further solution of the present invention: the clamping block forms a sliding fit with the limiting shaft, one end of the clamping block is fixedly connected to a clamping threaded rod, and the thread directions at both ends of the clamping threaded rod are opposite, and a bracket is fixedly connected to the outer wall of the guide rail close to the clamping threaded rod.

[0010] As a further solution of the present invention: the top of the bracket and the middle section of the limiting shaft are sleeved with each other, one end of the clamping threaded rod is fixedly connected to a crank, and the outer end of the clamping threaded rod is welded with a transmission rod.

[0011] As a further solution of the present invention: the passive positioner is internally rotatably connected to a lifting threaded rod, the two lifting threaded rods are externally connected to a passive lifting block through threads, a positioning block is welded to the outside of the passive lifting block, and a fixed block is embedded in the bottom of the positioning block.

[0012] As a further solution of the present invention: an active lifting block is welded to the other end of the positioning block, the active lifting block is connected to the outside of the lifting threaded rod through threads, and a rotary handle is fixedly connected to the top of the lifting threaded rod.

[0013] Compared with the prior art, the present invention provides a metal parts welding positioning tool, which has the following beneficial effects:

[0014] 1. This metal welding positioning tool is connected to the top of the guide rail through a slider via screws during welding. Then, two photovoltaic panels are placed flat on the work surface, and the slider is slid to the top of the photovoltaic panel where it needs to be positioned. This solves the problem that traditional metal welding positioning devices cannot change the positioning position at any time as the size of the photovoltaic panel changes during the welding process, thereby increasing the efficiency of the welding work.

[0015] 2. This metal welding positioning tool rotates the crank so that the two clamping threaded rods with opposite threads rotate in the direction of the crank, driving the clamping blocks to extend outward to the inside of the grooves on both sides. At the same time, the transmission rod rotates and extends outward as the clamping threaded rods rotate. Therefore, when the two sides of the photovoltaic panel that need to be positioned are determined, the guide rail fixes the slider through the clamping block, which facilitates the welding of the photovoltaic panel and prevents the slider from accidentally moving during welding and causing inaccurate positioning.

[0016] 3. This kind of metal welding positioning tooling, by rotating the handle, makes the lifting threaded rod at the bottom of the handle rotate along with the rotation direction of the handle, so that the positioning block drives the fixed block to move toward the bottom. Thus, when the two sides of the photovoltaic panel are placed on the bottom of the fixed block, the fixed block can just press it to fix it. The fixed block is made of rubber material and does not fix one corner of the photovoltaic panel alone. The pressure is evenly distributed, ensuring that the photovoltaic panel is not easily damaged during fixation, and can be adjusted according to the thickness of the photovoltaic panel, which increases the flexibility of the metal positioning tooling.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of this patent, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this patent.

[0025] In the description of this patent, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connection or set, detachable connection or set, or integral connection or set. Those skilled in the art will understand the specific meanings of the above terms in this patent based on the specific circumstances.

[0026] A metal parts welding positioning tool, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, it includes a workbench 1, wherein the four corners of the workbench 1 are provided with slots 2, a guide rail 3 is welded inside each slot 2, a slider 4 is movably connected to the top of the guide rail 3, screws 803 are threadedly connected to the top two sides of the slider 4, a passive locator 5 and an active locator 8 are fixedly connected to the top of the slider 4, and the passive locator 5 and the active locator 8 are a group.

[0027] During welding, the slider 4 is connected to the top of the guide rail 3 by screws 803, and then the two photovoltaic panels are placed flat on the workbench 1. Then the slider 4 is slid to the top of the photovoltaic panel where it needs to be positioned. This solves the problem that the traditional metal welding positioning device cannot change the positioning position at any time as the size of the photovoltaic panel changes during the welding process, thereby increasing the efficiency of the welding work.

[0028] In order to fix the slider 4 on both sides of the guide rail 3, as shown in FIG. Figure 2 As shown, grooves 801 are opened on both sides of the interior of the slider 4, and notches are opened on both sides of the top of the groove 801, and balls 802 are connected in rolling connection at equal distances in the notches. Clamping blocks 804 are connected to both sides of the guide rail 3 through threads, and the two sides of the guide rail 3 are fixedly connected to the limiting shaft 806, and the clamping block 804 forms a sliding fit with the limiting shaft 806. One end of the clamping block 804 is fixedly connected to the clamping threaded rod 808, and the thread directions of the two ends of the clamping threaded rod 808 are opposite. A bracket 807 is fixedly connected to the outer wall of the guide rail 3 on one side close to the clamping threaded rod 808, and the top of the bracket 807 is socketed with the middle section of the limiting shaft 806, one end of the clamping threaded rod 808 is fixedly connected to the crank 805, and a transmission rod 809 is welded to the outer end of the clamping threaded rod 808.

[0029] When fixing, by turning the crank 805, the clamping threaded rod 808 with two threads facing opposite directions rotates along the direction of rotation of the crank 805, driving the clamping block 804 to extend outward to the inside of the grooves 801 on both sides. At the same time, the transmission rod 809 rotates and extends outward along with the rotation of the clamping threaded rod 808. Therefore, when the two sides of the photovoltaic panel that needs to be positioned are determined, the guide rail 3 fixes the slider 4 through the clamping block 804, which facilitates the welding of the photovoltaic panel and prevents the slider from accidentally moving during welding and causing inaccurate positioning.

[0030] In order to ensure the positioning and fixation of photovoltaic panels, Figure 3 、 4 As shown, the passive positioner 5 is internally rotatably connected to a lifting threaded rod 9, and the two lifting threaded rods 9 are externally connected to a passive lifting block 10 through threads. A positioning block 7 is welded to the outside of the passive lifting block 10, and a fixed block 6 is embedded in the bottom of the positioning block 7. An active lifting block 12 is welded to the other end of the positioning block 7. The active lifting block 12 is connected to the outside of the lifting threaded rod 9 through threads, and a rotary handle 11 is fixedly connected to the top of the lifting threaded rod 9.

[0031] When fixing, the lifting threaded rod 9 at the bottom of the handle 11 is rotated in the direction of rotation of the handle 11 by rotating the handle 11, so that the positioning block 7 drives the fixing block 6 to move to the bottom. Therefore, when the two sides of the photovoltaic panel are placed on the bottom of the fixing block 6, the fixing block 6 can just press it to fix it. The fixing block 6 is made of rubber material and does not fix one corner of the photovoltaic panel alone. The pressure is evenly distributed, ensuring that the photovoltaic panel is not easily damaged when fixed, and can be adjusted according to the thickness of the photovoltaic panel, which increases the flexibility of the metal positioning tooling.

[0032] Working principle: the slider 4 is connected to the top of the guide rail 3 by the screw 803, and then the two photovoltaic panels are placed flat on the workbench 1, and then the slider 4 is slid to the top of the photovoltaic panel where it needs to be positioned and fixed, and then the crank 805 is turned to make the clamping threaded rods 808 with two threads facing opposite directions rotate with the rotation direction of the crank 805, driving the clamping block 804 to extend outward to the inside of the grooves 801 on both sides, and at the same time, the transmission rod 809 rotates and extends outward with the rotation of the clamping threaded rod 808, and the lifting threaded rod 9 at the bottom of the handle 11 is rotated by rotating the handle 11, so that the positioning block 7 drives the fixed block 6 to move to the bottom, thereby, when the two sides of the photovoltaic panel are placed on the bottom of the fixed block 6, the fixed block 6 can just press it down for fixing. The fixed block 6 is made of rubber material and does not fix one corner of the photovoltaic panel alone. The pressure is evenly distributed to ensure that the photovoltaic panel is not easily damaged when fixed.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
