Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a welding positioning fixture with cooling function. Background Technology

[0002] A fixture is a device used to fix a workpiece in place, ensuring it is in the correct position for processing or inspection; it is also called a clamp. Broadly speaking, any device used to quickly, conveniently, and safely install a workpiece at any stage of a manufacturing process can be called a fixture. For example, welding fixtures are often used to position components to be welded, ensuring accurate position and dimensions after welding.

[0003] The welding process generates high temperatures for components. To optimize welding quality, cooling is necessary at the welding location. Conventional cooling methods include air cooling and water cooling. For example, CN221337209U discloses a welding cooling device, including a welding table and a frame. A groove is provided at the front of the upper surface of the welding table, and multiple through holes are provided at the upper surface of the groove. A collection box is installed at the front of the lower surface of the welding table, and a water tank is installed at the rear end of the collection box. The water tank and the collection box are connected by a connecting groove, and a filter screen is installed inside the connecting groove. Support plates are installed at the front of both sides of the outer surface of the welding table. Multiple high-pressure nozzles are evenly installed above the opposite side of the outer surfaces of the two support plates. A water pump is installed below the opposite side of the outer surfaces of the two support plates. A connecting plate is installed at the front end of the frame.

[0004] This device can spray water to cool the workpiece. However, since the temperature of the parts is high after welding, the water flow is quickly lost on the surface of the parts due to the spraying method. Some of the water does not have a sufficient cooling effect before flowing away along the surface of the parts. It is necessary to spray for a long time to maintain the cooling effect, which reduces the cooling effect. Therefore, a welding positioning fixture with cooling function is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding positioning fixture with a cooling function, which has advantages such as improved cooling effect. It solves the problem that when using a spray method, water is quickly lost from the surface of the parts, and some water flows away along the surface of the parts before it has a sufficient cooling effect, requiring long-term spraying to maintain the cooling effect, thus reducing the cooling effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding positioning fixture with cooling function, comprising a bracket and a cooling box fixedly connected to the top of the bracket, a processing table is provided on the upper side of the cooling box, a clamping assembly is provided on the top of the processing table, an opening that runs vertically through the middle of the processing table, and a lifting mechanism is provided between the processing table and the cooling box.

[0007] The clamping assembly includes four mounting bases fixedly connected to the top of the processing table. Each of the four mounting bases has an adjusting screw threaded to its inner side, and a positioning head is rotatably connected to one end of the adjusting screw.

[0008] The lifting mechanism includes an electric push rod installed on the outside of the cooling box and a vertical rod fixedly connected to the top of the processing table. A connecting plate is fixedly connected to the upper end of the vertical rod, and the electric push rod is connected to the connecting plate.

[0009] Furthermore, the upper side wall of the cooling box is provided with a water inlet, and the lower side wall of the cooling box is provided with a drain outlet.

[0010] Furthermore, a drain port is provided at the bottom of the cooling box, and a handle is fixedly connected to the end of the adjusting screw away from the positioning head.

[0011] Furthermore, a partition net is fixedly installed on the outside of the opening, and the four mounting seats are symmetrically distributed in two groups on both sides of the partition net.

[0012] Furthermore, a mounting plate is fixedly connected to the outer wall of the cooling box, and the electric push rod is fixedly installed on the top of the mounting plate.

[0013] Furthermore, a connecting block is fixedly connected to the outer side of the connecting plate, and the output shaft of the electric push rod is fixedly connected to the connecting block.

[0014] Furthermore, a guide rod is fixedly connected to the inner wall of the cooling box, and an installation hole for the guide rod to pass through is provided on the inner side of the processing table. The outer wall of the guide rod is slidably engaged with the inner side of the installation hole.

[0015] Compared with the prior art, this utility model provides a welding positioning fixture with cooling function, which has the following beneficial effects:

[0016] 1. This welding positioning fixture with cooling function, when activated by the electric push rod, moves the connecting block downwards, which in turn moves the connecting plate downwards. The connecting plate then moves the processing table downwards via the vertical rod, thereby moving the processing table into the cooling box. The cooling water inside the cooling box then overflows onto the parts on the processing table through the opening, ensuring full contact between the cooling water and the parts. By immersing the parts, the cooling water ensures a sufficient cooling effect and good cooling performance.

[0017] 2. This welding positioning fixture with cooling function can discharge water from the cooling box through a drain outlet after the water temperature inside the cooling box rises, facilitating subsequent recycling. In addition, the sewage outlet facilitates the discharge of wastewater from the cooling box, making subsequent cleaning of the cooling box easier. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figs. 1 to 4 In this embodiment, a welding positioning fixture with cooling function includes a bracket 1 and a cooling box 2 fixedly connected to the top of the bracket 1. A processing table 3 is provided on the upper side of the cooling box 2.

[0025] The cooling box 2 has a water inlet 8 on its upper side wall, a drain outlet 9 on its lower side wall, and a sewage outlet 10 at its bottom. The processing table 3 has a through-hole 11 in its center, with a mesh screen 12 fixedly installed on the outside of the opening 11. The water inlet 8 facilitates the connection of pipes to supply cooling water into the cooling box 2. When the water temperature inside the cooling box 2 rises, it can be drained through the drain outlet 9 for subsequent recycling. The sewage outlet 10 facilitates the discharge of wastewater from the cooling box 2 for cleaning. The mesh screen 12 blocks the opening 11, preventing workpieces from falling into the cooling box 2 without obstructing water flow.

[0026] In this embodiment, a clamping assembly is provided on the top of the processing table 3. The clamping assembly includes four mounting seats 4 fixedly connected to the top of the processing table 3. The four mounting seats 4 are symmetrically distributed in two groups on both sides of the partition 12. An adjusting screw 5 is threadedly connected to the inner side of each of the four mounting seats 4. A positioning head 7 is rotatably connected to one end of the adjusting screw 5. A handle 6 is fixedly connected to the end of the adjusting screw 5 away from the positioning head 7. By rotating the handle 6, the adjusting screw 5 is rotated and moved, which in turn moves the positioning head 7. The positioning head 7 is used to clamp and fix the parts.

[0027] In this embodiment, a lifting mechanism is provided between the processing table 3 and the cooling box 2. The lifting mechanism includes an electric push rod 14 installed on the outside of the cooling box 2 and a vertical rod 15 fixedly connected to the top of the processing table 3. A connecting plate 16 is fixedly connected to the upper end of the vertical rod 15. The electric push rod 14 is connected to the connecting plate 16. A mounting plate 13 is fixedly connected to the outer wall of the cooling box 2. The electric push rod 14 is fixedly installed on the top of the mounting plate 13. A connecting block 17 is fixedly connected to the outside of the connecting plate 16. The output shaft of the electric push rod 14 is fixedly connected to the connecting block 17. By starting the electric push rod 14, the connecting block 17 can be moved up and down, and the connecting plate 16 can be moved up and down. The connecting plate 16 will then move the processing table 3 up and down through the vertical rod 15, which facilitates the adjustment of the height of the processing table 3.

[0028] It should be noted that in this embodiment, the number of lifting mechanisms is set to two sets, and the two electric push rods 14 can be synchronously controlled by a synchronous controller to ensure the stable lifting of the processing table 3.

[0029] It should be noted that a guide rod 18 is fixedly connected to the inner wall of the cooling box 2, and a mounting hole 19 for the guide rod 18 to pass through is opened on the inner side of the processing table 3. The outer wall of the guide rod 18 slides with the inner side of the mounting hole 19. The cooperation between the guide rod 18 and the mounting hole 19 can guide the processing table 3 and improve the stability of the structure.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, the inlet 8 can be connected to a pipe to deliver cooling water into the cooling tank 2. The parts are clamped by the clamping assembly on the top of the processing table 3. After welding is completed, the electric push rod 14 is activated to move the connecting block 17 downward and the connecting plate 16 downward. The connecting plate 16 will then move the processing table 3 downward through the vertical rod 15, thereby moving the processing table 3 into the cooling tank 2. The cooling water inside the cooling tank 2 will then overflow the parts on the processing table 3 through the opening 11, so that the cooling water is in full contact with the parts. By immersing, the cooling water is ensured to have a sufficient cooling effect. The cooling effect is good. When the water temperature inside the cooling tank 2 rises, it can be discharged from the tank through the drain outlet 9 to facilitate subsequent recycling.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.

[0033] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
