Description

Technical Field

[0001] This utility model relates to the field of subway gearbox processing technology, specifically to a welding heat dissipation device for subway gearbox processing. Background Technology

[0002] The subway gearbox is a key component in a subway system used to regulate the output power of the electric motor, enabling the subway to move forward and stop. Its main function is to convert the power output from the electric motor into mechanical energy through gear transmission, thereby controlling the subway's speed and direction.

[0003] The manufacturing process of subway gearboxes requires welding. To achieve better welding results, timely cooling is necessary after welding. Some existing welding devices use blowers for cooling, but the airflow direction cannot be adjusted, making it difficult to cool irregular weld areas. During the welding process, the welding device generates a large number of sparks and welding slag. These sparks and welding slag are at high temperatures and splash in all directions during processing, posing certain safety hazards. Utility Model Content

[0004] This invention provides a welding heat dissipation device for subway gearbox processing, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides a welding heat dissipation device for processing subway gearboxes, comprising:

[0007] Workbench;

[0008] A base, which is welded to the lower surface of the workbench;

[0009] A cooling device is fixedly installed on the upper surface of the workbench, which enables the air outlet to be adjusted after welding to facilitate uniform heat dissipation from multiple angles during welding.

[0010] A protective device is slidably connected to the side wall of the workbench to provide protection during equipment use, preventing sparks and welding slag from splashing and causing safety hazards.

[0011] Through the above technical solutions, the cooling device allows the equipment to quickly adjust the position of the air outlet after welding is completed, thereby rapidly cooling the weld area and improving the welding effect. The protective device blocks sparks and high-temperature welding slag that are splashed during the welding process, reducing the damage to personnel and equipment caused by splashing and lowering the risk.

[0012] Furthermore, the cooling device includes a lifting column, which is fixedly connected to the upper surface of the worktable. A lifting platform is slidably connected to the side wall of the lifting column. A locking bolt is threadedly connected to the side wall of the lifting platform, and the locking bolt penetrates the side wall of the lifting platform and contacts the lifting column. A fan is fixedly installed on the upper surface of the base. A diversion interface is fixedly installed at the output end of the fan. A guide pipe is fixedly connected to the outer circumference of the diversion interface. A square groove is formed on the upper surface of the worktable, and the square groove penetrates the worktable. An air outlet is fixedly installed on the lower surface of the lifting platform, and the guide pipe penetrates the square groove and is fixedly connected to the air outlet.

[0013] Using the above technical solution, after welding is completed, the lifting platform is pulled to the welding position on the lifting column, the locking bolt is turned to lock the position of the lifting platform, the fan is started, and the airflow enters the air duct after passing through the diversion interface, and then blows out through the air outlet to quickly cool down the weld.

[0014] Furthermore, a threaded sleeve is threaded to the outer circumference of the air outlet, and a metal hose is threaded to the end of the threaded sleeve away from the air outlet. Both the air outlet and the metal hose have sealing rings nested on their outer circumferences.

[0015] The above technical solution connects the air outlet and the metal hose with a threaded sleeve, which facilitates the installation and disassembly of both. The sealing ring improves the airtightness of the connection. After connecting the metal hose, the airflow can be more precisely regulated, which better assists in welding.

[0016] Furthermore, a top plate is fixedly connected to the upper surface of the lifting column.

[0017] The above technical solution prevents the lifting platform from detaching itself when it moves too high on the lifting column.

[0018] Furthermore, a limit block is fixedly connected to the upper surface of the workbench, and a buffer pad is glued to the upper surface of the limit block.

[0019] The above technical solution includes setting a limit block to prevent the air outlet and air duct from being squeezed and damaged by the lifting platform during the descent, and a buffer pad to reduce wear between the lifting platform and the limit block.

[0020] Furthermore, the protective device includes a sliding block, which is fixedly connected to the lower surface of the workbench. The workbench and the side wall of the sliding block are provided with sliding grooves. A slider is slidably connected to the inner wall of the sliding groove. A protective plate is fixedly connected to the side wall of the slider. A fixing sleeve is fixedly installed on the upper surface of the workbench. A fixing tongue is slidably connected to the inner wall of the fixing sleeve. A fixing hole is provided on the side wall of the protective plate to engage with the fixing tongue.

[0021] With the above technical solution, when welding is required, the protective plate is pulled up on the worktable, which drives the slider to move on the sliding groove. The fixing tongue on the fixing sleeve is pushed to engage with the fixing hole to fix the position of the protective plate. The protective plate blocks the sparks and welding slag generated during welding.

[0022] Furthermore, a handle is fixedly connected to the side wall of the protective plate.

[0023] The above technical solution makes it easy to pull up and reset the protective plate.

[0024] Furthermore, a buffer cylinder is fixedly connected to the bottom of the inner cavity of the sliding block, a buffer spring is slidably connected to the inner circumference of the buffer cylinder, a buffer column is slidably connected to the inner circumference of the buffer cylinder, and the buffer spring is located between the buffer cylinder and the buffer column.

[0025] With the above technical solution, the protective plate falls, causing the slider to move up and down in the sliding groove. The slider contacts the buffer column, causing it to move down and compressing the buffer spring in the buffer cylinder. The buffer spring's reaction force resists the slider, reducing the impact on the sliding block when the protective plate resets.

[0026] The above-described solution of this utility model has at least the following beneficial effects:

[0027] This invention utilizes a cooling device to adjust the position of the air nozzle by moving a lifting platform on a lifting column after welding. This facilitates cooling of the welded area and improves the welding effect. Simultaneously, a threaded sleeve connects the air nozzle to the metal hose, allowing for more precise adjustment of the airflow direction and better assisting in welding.

[0028] This utility model, through a protective device, allows the protective plate to be pulled up on the workbench when the equipment needs to be used, and the fixing tongue on the fixing sleeve to engage with the fixing hole, thereby locking the position of the protective plate, thus blocking the sparks and welding slag generated during the welding process, preventing them from splashing in all directions, and reducing safety hazards.

[0037] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0038] like Figure 1 As shown, an embodiment of this utility model provides a welding heat dissipation device for processing subway gearboxes, comprising: a workbench 1; a base 2, the base 2 being welded to the lower surface of the workbench 1; a cooling device 3, the cooling device 3 being fixedly installed on the upper surface of the workbench 1 to achieve uniform heat dissipation from multiple angles after welding; and a protective device 4, the protective device 4 being slidably connected to the side wall of the workbench 1 to provide protection during equipment use and prevent sparks and welding slag from splashing, thus avoiding safety hazards.

[0039] like Figures 1 to 5As shown, the cooling device 3 includes a lifting column 301, which is fixedly connected to the upper surface of the workbench 1. A lifting platform 302 is slidably connected to the side wall of the lifting column 301. A locking bolt 303 is threadedly connected to the side wall of the lifting platform 302, and the locking bolt 303 penetrates the side wall of the lifting platform 302 and contacts the lifting column 301. A fan 304 is fixedly installed on the upper surface of the base 2. A diversion interface 305 is fixedly installed at the output end of the fan 304. A guide pipe 306 is fixedly connected to the outer circumference of the diversion interface 305. A square groove is formed on the upper surface of the workbench 1, and the square groove penetrates the workbench 1. An air outlet 307 is fixedly installed on the lower surface of the lifting platform 302. An air duct 306 passes through the square groove and is fixedly connected to the air outlet 307. After welding is completed, the lifting platform 302 is pulled up on the lifting column 301 to move it to the welding height position. The locking bolt 303 is rotated to lock the position of the lifting platform 302. Simultaneously, the fan 304 is started, driving airflow through the diversion interface 305 into the air duct 306, and then blowing it out through the air outlet 307 to cool the weld area. The diversion interface 305 allows airflow to be blown out through two air outlets 307, expanding the cooling range. Larger and more uniform, the square groove reduces interference of the air guide duct 306 with other components of the equipment. A threaded sleeve 308 is threaded onto the outer circumference of the air outlet 307. A metal flexible hose 309 is threaded onto the end of the threaded sleeve 308 furthest from the air outlet 307. Sealing rings 310 are nested on the outer circumference of both the air outlet 307 and the metal flexible hose 309. The connection is achieved through the threaded sleeve 308, facilitating the installation and removal of the metal flexible hose 309 from the air outlet 307. The sealing rings 310 improve the airtightness between the two during connection, and the metal flexible hose 309 is easy to bend and shape, allowing airflow to enter... More precise adjustments are made to better assist welding. A top plate 311 is fixedly connected to the upper surface of the lifting column 301. The top plate 311 prevents the lifting platform 302 from being pulled too high on the lifting column 301 and falling off. A limit block 312 is fixedly connected to the upper surface of the worktable 1. A buffer pad 313 is glued to the upper surface of the limit block 312. The limit block 312 prevents the lifting platform 302 from contacting the worktable 1 too tightly when it descends, thereby squeezing the air outlet 307 and the air guide pipe 306 and causing damage. The buffer pad 313 reduces wear between the limit block 312 and the lifting platform 302.

[0040] In this embodiment of the utility model, after welding is completed, the lifting platform 302 is pulled up on the lifting column 301 to move it to the welding height position. The locking bolt 303 is rotated to lock the position of the lifting platform 302. At the same time, the fan 304 is started, and the airflow is driven through the diversion interface 305 and into the air duct 306. The air is blown out through the air outlet 307 to cool the weld. The threaded sleeve 308 makes it easy to connect the air outlet 397 to the metal hose 309. The metal hose 309 is easy to bend and shape, so the direction of the blown airflow can be adjusted more precisely, which can better assist in heat dissipation of the welding.

[0041] like Figures 1 to 6 As shown, the protective device 4 includes a sliding block 401, which is fixedly connected to the lower surface of the workbench 1. A sliding groove 402 is provided on the side wall of the workbench 1 and the sliding block 401. A slider 403 is slidably connected to the inner wall of the sliding groove 402. A protective plate 404 is fixedly connected to the side wall of the slider 403. A fixing sleeve 405 is fixedly installed on the upper surface of the workbench 1. A fixing tongue 406 is slidably connected to the inner wall of the fixing sleeve 405. A fixing hole 407 is provided on the side wall of the protective plate 404 to engage with the fixing tongue 406. When the equipment needs to be used, the protective plate 404 is pulled up, causing the slider 403 to slide on the sliding groove 302. The sliding block 301 ensures that the sliding groove 302 has sufficient length for easy pulling and retraction of the protective plate 304. By pushing the fixing tongue 406 on the fixing sleeve 405, it engages with the fixing hole 407 on the protective plate 404, thereby locking the protective plate 404. The protective plate 404 is positioned to effectively block and protect against sparks and high-temperature slag generated during welding, preventing them from splashing everywhere and causing safety hazards. A handle 408 is fixedly connected to the side wall of the protective plate 404, which facilitates the movement of the protective plate 404 to pull up and reset. A buffer cylinder 409 is fixedly connected to the bottom of the inner cavity of the sliding block 401. A buffer spring 410 is slidably connected to the inner circumference of the buffer cylinder 409, and a buffer column 411 is slidably connected to the inner circumference of the buffer cylinder 409. The buffer spring 410 is located between the buffer cylinder 409 and the buffer column 411. When the protective plate 404 is reset, the protective plate 404 falls, causing the slider 403 to move down in the sliding groove 302. The slider 403 contacts the buffer column 411, causing it to move down together and compress the buffer spring 410 in the buffer cylinder 409. The reaction force of the compressed buffer spring 410 supports the slider 403, thereby reducing the impact when the protective plate 404 resets and falls.

[0042] In this embodiment of the invention, when the equipment is to be used, the protective plate 404 is pulled up by the handle 408, causing the slider 403 to slide on the sliding groove 302. The fixing tongue 406 is pushed on the fixing sleeve 405 to engage with the fixing hole 407 on the protective plate 404, thereby locking the position of the protective plate 404. This facilitates the blocking and protection of sparks and high-temperature slag generated during welding, preventing them from splashing everywhere and causing safety hazards. After the equipment has finished working, the protective plate 404 is released from its lock to reset it. As the protective plate 404 falls, it causes the slider 403 to move down in the sliding groove 302. After the slider 403 contacts the buffer column 411, it moves down together with the buffer column 411, compressing the buffer spring 410 in the buffer cylinder 409. The buffer spring 410 supports the slider 403 under the reaction force of the compression, thereby reducing the impact when the protective plate 404 resets and falls.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
