Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a laser marking device suitable for brass ball valves. Background Technology

[0002] There is a brass ball valve 22, such as Figure 1-2 As shown, it is a small ball valve. The valve body 221 is hexagonal in shape. The top of the valve body 221 is provided with a square handle 222 that can rotate 90 degrees to control the opening and closing of the valve core. A mark 223 is printed on one side near the handle 222 by a marking machine.

[0003] Currently, our company primarily uses manual marking for this brass ball valve. However, this method has several drawbacks. On the one hand, manual marking is inefficient and cannot meet the demands of mass production, severely restricting production progress. On the other hand, manual control of the marking process cannot guarantee sufficient precision, resulting in inconsistent marking quality that fails to meet existing production standards and quality requirements. Therefore, improvements are urgently needed to enhance both production efficiency and marking quality. Utility Model Content

[0004] The purpose of this invention is to provide a laser marking device suitable for brass ball valves, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser marking device for brass ball valves includes a vertical laser marking machine and a ball valve assembly that can be quickly and detachably connected to the working platform of the vertical laser marking machine. The ball valve assembly is limited and connected to the working platform of the vertical laser marking machine by a limiting block, which enables the ball valve assembly to be limited and precisely positioned for marking on the working platform. The brass ball valve to be marked has an external hexagonal valve body, and a square handle that can rotate 90 degrees at the top of the valve body to control the opening and closing of the valve core. One side near the handle needs to be marked by the marking machine.

[0007] The ball valve assembly includes a ball valve limiting platform and brass ball valves uniformly arranged on the ball valve limiting platform; the ball valve limiting platform is integrally formed and connected by several limiting units; the handle of the brass ball valve is set at 90 degrees to the valve body.

[0008] The limiting unit includes a base, a U-shaped first groove, a V-shaped second groove disposed on the base, and a positioning post disposed at the bottom of the first groove; the first groove matches the external hexagonal valve body of the brass ball valve, and the bottom of the valve body of the brass ball valve abuts against the first groove for limiting; the second groove matches the tail of the handle, and the tail of the handle abuts against the second groove for limiting, thereby realizing the limiting connection and positioning of the brass ball valve through the limiting unit.

[0009] Preferably, the ball valve limiting platform is cuboid in shape and includes two rows of symmetrically arranged limiting units. The cuboid geometry facilitates the limiting connection of the ball valve limiting platform on the working platform of the vertical laser marking machine.

[0010] Preferably, each row of limiting units is arranged at equal intervals along a straight line, and adjacent brass ball valves are positioned at intervals through the positioning column. The equal interval arrangement facilitates the printing layout of the vertical laser marking machine.

[0011] Preferably, the limiting block is in contact with the three adjacent sides of the ball valve limiting platform, thereby limiting the ball valve assembly in three directions on the vertical laser marking machine working platform. This satisfies the printing positioning requirements while leaving one direction for quick separation.

[0012] Preferably, the limiting blocks include a first limiting plate, a second limiting plate, and a third limiting plate, which are respectively connected to the three adjacent sides of the ball valve limiting platform in a contactable limiting manner, so as to meet the needs of quick limiting connection and separation between ball valve limiting platforms of different specifications and the working platform of the vertical laser marking machine, which is flexible and practical.

[0013] Preferably, the first, second, and third limiting plates are each provided with a through-hole elongated hole, which facilitates fine-tuning of the first, second, and third limiting plates on the working platform of the vertical laser marking machine.

[0014] Compared with the prior art, the laser marking device for brass ball valves proposed in this application has the following advantages:

[0015] 1. High-efficiency mass production: Through the multi-station integrated design of the ball valve limiting platform, combined with the equidistant linear arrangement of the limiting units, the synchronous and precise positioning of multiple brass ball valves is achieved. The vertical laser marking machine can complete the marking of an entire row of panels in one go, significantly shortening the production cycle and meeting the needs of large-volume orders.

[0016] 2. Improved positioning accuracy: The system adopts a U-shaped first groove with geometric matching with the hexagonal valve body, and a V-shaped second groove with double limiting at the end of the handle. Combined with the axial constraint of the positioning column, a three-dimensional positioning system is formed, resulting in small marking position deviation. This solves the problems of marking offset and inconsistent depth caused by manual operation, and significantly improves the yield rate.

[0017] 3. Flexible Adaptability: The three independent limiting plate design (first, second, and third limiting plates) combined with the through-hole structure allows for easy adjustment of the spacing and angle of the limiting plates, resulting in good adaptability. The three-sided contact positioning of the limiting blocks ensures accurate positioning while retaining an open channel on the fourth side, enabling quick assembly and disassembly of the ball valve assembly and significantly shortening the production cycle.

[0018] 4. Scalability: The modularly designed ball valve limit platform supports multi-row expansion, and flexible configuration of multiple workstations can be achieved by increasing or decreasing the number of limit units. Attached Figure Description

[0031] The following detailed description illustrates the specific implementation method:

[0032] Example 1

[0033] like Figure 1-11 As shown, this embodiment illustrates a laser marking device suitable for a brass ball valve 22, including a vertical laser marking machine 1 and a ball valve assembly 2 that can be quickly detached and connected to the working platform 11 of the vertical laser marking machine. The ball valve assembly 2 is limited and connected to the working platform 11 of the vertical laser marking machine by a limiting block 3. The limiting block 3 achieves the limiting connection and precise marking positioning of the ball valve assembly 2 on the working platform 11, that is, the limiting block 3 limits the ball valve assembly 2 to a pre-set marking range area on the working platform 11. It should be noted that the brass ball valve 22 to be marked in this embodiment is, for example... Figure 1-2 As shown, its valve body 221 is hexagonal in shape, and the top of the valve body 221 is provided with a square handle 222 that can be rotated 90 degrees to control the opening and closing of the valve core. A mark 223 needs to be printed on one side near the handle 222 by a marking machine.

[0034] In this embodiment, the ball valve assembly 2 includes a ball valve limiting platform 21 and a brass ball valve 22 disposed on the ball valve limiting platform 21. The ball valve limiting platform 21 is integrally formed and connected by a plurality of limiting units 23. The handle 222 of the brass ball valve 22 is set at a 90-degree angle to the valve body 221. The modularly designed ball valve limiting platform 21 supports expansion; flexible multi-station configurations can be achieved by increasing or decreasing the number of limiting units 23.

[0035] like Figure 9-11 As shown, in this embodiment, the limiting unit 23 includes a base 231, a U-shaped first groove 232 and a V-shaped second groove 233 disposed on the base 231, and a positioning post 234 disposed at the bottom of the first groove 232; the first groove 232 matches the outer hexagonal valve body 221 of the brass ball valve 22, and the bottom of the valve body 221 of the brass ball valve 22 is limited and abutted against the first groove 232; the second groove 233 matches the tail of the handle 222, and the tail of the handle 222 is limited and abutted against the second groove 233, thereby realizing the limiting connection and positioning of the brass ball valve 22 through the limiting unit 23.

[0036] To further explain, in a further possible implementation of this embodiment, such as Figure 2-3 As shown, the ball valve limiting platform 21 is in the shape of a cuboid and includes two rows of symmetrically arranged limiting units 23. The cuboid geometry facilitates the limiting connection of the ball valve limiting platform 21 on the working platform 11 of the vertical laser marking machine.

[0037] In actual marking work, the brass ball valve 22 is first placed on the ball valve limiting platform 21, wherein the external hexagonal valve body 221 is placed on the cover of the first groove 232, and the tail of the handle 222 is placed on the second groove 233. The axial end face of the external hexagonal valve body 221 is limited and connected to the positioning column 234. Then, the ball valve assembly 2 is limited and connected to the upper limit block 3 of the vertical laser marking machine working platform 11. The vertical laser marking machine 1 has a pre-set marking layout program according to the arrangement specifications of the brass ball valves 22 within the marking range, and then laser marking can begin.

Further explanation is provided in a further feasible implementation of this embodiment, such as... Figure 6-8 As shown, each row of limiting units 23 is arranged at equal intervals along a straight line. Adjacent brass ball valves 22 are positioned at intervals via positioning posts 234. Through the multi-station integrated design of the ball valve limiting platform 21, combined with the equally spaced linear arrangement of the limiting units 23, synchronous and precise positioning of multiple brass ball valves 22 is achieved. The vertical laser marking machine 1 can complete the marking operation of an entire row of panels in one go, significantly shortening the production cycle and meeting the needs of large-volume orders.

[0040] To further explain, in these embodiments, such as Figure 3-5 As shown, the limiting block 3 is connected to the three adjacent sides of the ball valve limiting platform 21 in a contactable limiting manner. The three-sided contact positioning of the limiting block 3 ensures accurate positioning while retaining an open channel on the fourth side, enabling quick assembly and disassembly of the ball valve assembly 2.

[0042] like Figure 1-11 As shown, another embodiment, based on embodiment 1, demonstrates a laser marking device suitable for a brass ball valve 22. Further explanation is provided in a further feasible implementation of this embodiment, such as... Figure 3-5As shown, the limiting block 3 includes a first limiting plate 31, a second limiting plate 32 and a third limiting plate 33, which are respectively connected to the three adjacent sides of the ball valve limiting platform 21 in a contactable limiting manner, so as to meet the needs of quick limiting connection and separation between the ball valve limiting platform 21 of different specifications and the working platform 11 of the vertical laser marking machine, which is flexible and practical.

[0043] To further explain, in these embodiments, such as Figure 2-3 As shown, the first limiting plate 31, the second limiting plate 32 and the third limiting plate 33 are each provided with a through-hole elongated hole 34, which facilitates the fine adjustment of the first limiting plate 31, the second limiting plate 32 and the third limiting plate 33 on the working platform 11 of the vertical laser marking machine.
