Description

Technical Field

[0001] This application relates to the field of flame cap processing equipment, and in particular to a stainless steel flame cap drilling device. Background Technology

[0002] The burner cap is a core functional component of a gas stove, playing a crucial role in supporting the cookware, guiding the mixing of gas and air, evenly distributing the flame, and preventing backfire. (Refer to...) Figure 1 A flame cap includes a flame cap body 1 and a flame hole assembly 2. The flame cap body 1 is an annular independent cavity responsible for concentrating the central fire and expanding the flame coverage area. The flame hole assembly 2 includes a number of densely packed holes 21 distributed circumferentially on the flame cap body 1, which are channels for the combustion of the gas mixture with air.

[0003] In related technologies, the drilling of flame caps is mainly done manually, relying on basic equipment such as bench drills. Operators hold the flame cap by hand or use simple fixtures to position it before drilling. For flame holes with an inclined angle, the flame cap posture needs to be manually adjusted. After drilling one hole, the workpiece is manually rotated by indexing plate to achieve continuous processing. After processing, it needs to be manually transferred to the next process.

[0004] Regarding the aforementioned technologies, in actual mass production scenarios, when operators hold the flame cap by hand or use simple clamps for positioning, it is difficult to ensure that the tilt angle, drilling depth, and center distance of each flame hole are consistent. This can easily lead to problems such as "skewed" or "uneven depth" flame holes, resulting in an unbalanced flame distribution when the flame cap is in use. Some areas may have excessively strong firepower, while others may have weak firepower. In some cases, excessively high local gas concentrations may even cause backfire safety hazards. Utility Model Content

[0005] To address the problem that manual assisted processing of flame caps can easily lead to variations in flame hole specifications, resulting in an unbalanced flame distribution during flame cap use, this application provides a stainless steel flame cap drilling device.

[0006] The stainless steel flame cap drilling device provided in this application adopts the following technical solution: A stainless steel flame cap drilling device includes a cutting pool, a clamping module disposed in the cutting pool for clamping and rotating the flame cap, and at least one drilling module for drilling holes in the flame cap. The punching module includes a mounting base fixedly connected to the cutting pool, a punching assembly slidably connected to the mounting base, and a sliding assembly that drives the punching assembly to move closer to or away from the clamping module. The drilling assembly includes a drilling motor fixedly connected to the sliding assembly and a drill bit arranged on the output shaft of the drilling motor, with the output shaft of the drilling motor facing the clamping module.

[0007] By adopting the above technical solution, the sliding component drives the drilling component to move closer to or further away from the clamping module, and the drilling motor drives the drill bit to rotate and drill holes in the flame cap. This ensures that the flame hole tilt angle, drilling depth and hole center distance are consistent, reducing the probability of flame holes being "skewed" or "uneven in depth", thereby reducing the backfire safety hazard and improving the safety of using the flame cap.

[0008] Optionally, the sliding assembly includes a sliding stage fixedly connected to the mounting base, a mounting platform slidably connected to the sliding stage along a direction close to or away from the clamping module, a drive screw rotatably connected to the mounting platform, and a drive motor with an output shaft fixedly connected to one end of the drive screw, wherein the drive screw and the sliding stage are threadedly connected.

[0009] By adopting the above technical solution, the drive motor drives the drive screw to rotate. Since the drive screw is threadedly connected to the sliding table, when the drive screw rotates, the mounting table will slide on the sliding table in the direction of approaching or moving away from the clamping module, thereby improving the convenience of the drilling assembly approaching or moving away from the clamping module.

[0010] Optionally, the mounting platform is provided with at least one sliding groove, and a protrusion embedded in the sliding groove is fixedly connected to the sliding platform.

[0011] By adopting the above technical solution, the embedded cooperation between the sliding groove and the protrusion provides precise guidance for the movement of the mounting platform, so that the drilling component always moves closer to or further away from the clamping module in a straight line, reducing the probability of the mounting platform shifting during sliding and improving the sliding stability of the sliding groove and the sliding platform.

[0012] Optionally, the mounting base includes an adjustment rail fixedly connected vertically within the cutting pool, an adjustment platform slidably connected to the adjustment rail for mounting the sliding assembly, and an adjustment screw rotatably connected to the adjustment rail and threadedly connected to the adjustment platform.

[0013] By adopting the above technical solution, rotating the adjusting screw drives the adjusting table to slide along the adjusting track in the height direction, thereby adjusting the height position of the drilling component. It can adapt to flame caps of different sizes and different flame hole height requirements without replacing the entire drilling module, thus improving the versatility of the equipment.

[0014] Optionally, the adjustment platform includes a sliding part and a rotating part rotatably connected to the side of the sliding part away from the adjustment track. The rotating part is provided with an arc-shaped hole, and the sliding part is threaded with a locking screw that passes through the arc-shaped hole and has its screw head pressed against the side of the rotating part away from the sliding part.

[0015] By adopting the above technical solution, after the locking screw is loosened, the rotating part can rotate relative to the sliding part around the connection point. The angle can be adjusted by the limit of the arc hole, which can adapt to the processing requirements of fire holes with different tilt angles on the fire cap, and further improve the versatility of the equipment.

[0016] Optionally, a plurality of protruding posts are fixedly connected to the sliding part, and the rotating part is provided with arc-shaped grooves corresponding to the protruding posts one by one, with the protruding posts passing through and sliding in the arc-shaped grooves.

[0017] By adopting the above technical solution, the convex post and the arc groove provide additional guidance for the rotation of the rotating part, ensuring that the rotating part is smoothly adjusted along the arc groove trajectory, avoiding deviation or shaking, and improving the rotational stability of the rotating part; on the other hand, the convex post can enhance the connection stability between the rotating part and the sliding part, reduce the negative impact of drilling vibration on angle positioning, and effectively improve the machining accuracy of the inclined fire hole.

[0018] Optionally, the stainless steel burner punching device also includes a cutting fluid circulation module, which includes a water pump extending into the cutting pool and a guide pipe with one end connected to the water pump and the other end of the guide pipe facing the drill bit.

[0019] By adopting the above technical solution, the water pump extracts the cutting fluid from the cutting pool and accurately delivers it to the machining parts of the drill bit and the burnisher through the guide pipe, realizing the recycling of the cutting fluid without frequent replacement, which significantly reduces the cost of machining consumables.

[0020] Optionally, the cutting pool includes a cutting pool body and a water storage tank connected to the cutting pool body, and the height of the bottom of the cutting pool gradually decreases from the side away from the water storage tank to the side closer to the water storage tank.

[0021] By adopting the above technical solution, the inclined bottom of the cutting pool uses gravity to guide the cutting fluid and metal chips to flow naturally towards the water storage tank, realizing automatic return and centralized collection of the cutting fluid, and simplifying the cutting fluid collection process.

[0022] Optionally, the water pump is equipped with a filter at the inlet.

[0023] By adopting the above technical solution, metal chips and impurities in the cutting fluid are filtered out by the filter when the water pump draws the cutting fluid. This effectively reduces the probability that impurities will enter the water pump or block the guide pipe with the cutting fluid, thus reducing the risk of equipment failure. On the other hand, the clean cutting fluid effectively prevents impurities from scratching the machined surface of the burner cap, reducing the cost of equipment maintenance and consumable replacement.

[0024] Optionally, the stainless steel burner punching equipment also includes a plurality of baffles arranged circumferentially along the cutting pool, the plurality of baffles being connected end to end to enclose the cutting pool.

[0025] By adopting the above technical solution, the enclosed baffle effectively blocks the splashing of cutting fluid and metal chips during the drilling process, reducing the probability of cuts and other injuries to operators caused by chip splashing, and improving the safety and ease of operation of the equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a drilling motor to drive the drill bit to drill holes in the flame cap, ensuring consistent flame holes and improving the safety of using the flame cap; 2. This application uses the rotation of the adjusting screw to drive the adjusting table to slide along the adjusting track in the height direction, thereby adjusting the height position of the drilling component, which improves the versatility of the equipment; 3. This application uses a water pump to extract the cutting fluid from the cutting pool and delivers it precisely to the machining parts of the drill bit and the burner cap through a guide pipe, thereby realizing the recycling of the cutting fluid and reducing the cost of machining consumables.

[0047] The implementation principle of a stainless steel flame cap drilling device according to an embodiment of this application is as follows: Align the flame cap to be processed with the three-jaw chuck body 412, and make the three jaws of the three-jaw chuck body 412 press against the inner wall of the flame cap so that the flame cap is stably clamped; rotate the adjusting screw 513 to drive the sliding part 514 to slide smoothly along the height direction until the drill bit 532 of the drilling assembly 53 is aligned with the height of the target hole 21; then loosen the locking screw 5141 and rotate the rotating part 515. After the tilt angle of the drill bit 532 is consistent with the angle of the target flame hole, tighten the locking screw 5141 to lock the rotating part 515. The drilling motor 531 is started, driving the drill bit 532 to rotate at high speed. At the same time, the drive motor 524 drives the drive screw 523 to rotate, driving the mounting table 522 to move synchronously closer to the three-jaw chuck body 412 until the drill bit 532 contacts and penetrates the surface of the flame cap, thus drilling a hole in the flame cap. Then the drive motor 524 rotates in the opposite direction, driving the drill bit 532 to retract from the hole 21. When a hole 21 is completed, the drive motor 421 rotates and drives the mounting plate 411 and the held flame cap to rotate synchronously to the next hole position through the belt 423. The above drilling action is repeated until all flame holes are completed. During the drilling process, the water pump 61 draws cutting fluid from the water tank 32. The cutting fluid is then transported to the processing area of ​​the drill bit 532 and the flame cap through the guide pipe 62. Under the gravity guidance of the inclined bottom of the cutting pool body 31, it flows back from the cutting pool body 31 to the water tank 32, realizing the recycling of the cutting fluid.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
