Description

Technical Field

[0001] This invention belongs to the field of graphite heat exchanger technology, specifically a high-precision device for processing graphite heat exchanger heads. Background Technology

[0002] A graphite heat exchanger head is a device that connects the two ends of a graphite heat exchanger via flanges, forming a closed chamber inside the graphite heat exchanger. High-precision equipment for processing graphite heat exchanger heads is used to weld the connection between the bottom of the head and the top of the flange. It mainly consists of an electric welding gun head. This high-precision equipment for processing graphite heat exchanger heads is primarily suitable for processing small parts to save costs.

[0003] The existing high-precision equipment for processing graphite heat exchanger heads involves workers first placing the bottom of the head and the top of the flange in a corresponding position, and then experienced technicians using welding guns to precisely weld the gap between the head and the flange.

[0004] In small processing plants, the welding process for high-precision equipment used in the processing of graphite heat exchanger heads is still mainly done manually. Manual welding is inherently slow because it is necessary to weld the joints firmly to ensure safe use later. However, if there are many welding tasks, the workload and physical exertion of the workers will increase, resulting in a decrease in work efficiency after processing one part, which will affect the overall work progress. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the problems mentioned in the background art, the present invention provides a high-precision device for processing graphite heat exchanger heads, solving the problem that experienced operators cannot quickly hand-hold a welding gun to weld heads and flanges when processing a large number of head parts.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-precision device for processing graphite heat exchanger heads, comprising a pressing mechanism, a motor fixedly connected to the top of the pressing mechanism, a switch button provided on the top of the motor, four support components fixedly connected in a ring on the outer surface near the top of the pressing mechanism, and a sealing shell movably connected to the bottom of the pressing mechanism via an arc-shaped rubber pad, wherein a flange ring is electrically welded to the outer edge of the sealing shell.

[0009] The second electric telescopic component is fixedly connected to one side of the outer edge of the support component, and the bottom of the second electric telescopic component is telescopically connected to the outer slide rail.

[0010] A first electric telescopic component is connected to one side of each of the four support components via a pivot. A suction cup is fixedly connected to the bottom of the first electric telescopic component. The height of the pressing mechanism can be adjusted by raising and lowering the bottom of the first electric telescopic component. The support components and the first electric telescopic component are connected in an L-shape to provide main support to the ground.

[0011] The bottom two-thirds of the pressing mechanism is provided with a limit component and a threaded ring from top to bottom.

[0012] Preferably, an arc rod is annularly connected to the bottom of the pressing mechanism at the top outer surface of the threaded ring. An inner slide rail is fixedly connected to one side of the arc rod at the bottom of the pressing mechanism. A ball head is slidably engaged in the outer groove of the inner slide rail. The other side of the ball head is slidably engaged in the outer slide rail through the groove. A welding pen is fixedly connected to the ball head. The bottom of the welding pen is located at the connection between the sealing part and the flange ring. The ball head includes a round-headed slide rod, and the inner wall of the round-headed slide rod is inclined.

[0013] Preferably, the bottom of the pressing mechanism is fixedly connected to a ring on the top surface of the limiting component, and an L-shaped rod is slidably engaged with the inner wall of the annular groove on the outer surface of the ring. The bottom of the L-shaped rod is fixedly connected to a limiting toothed sleeve.

[0014] Preferably, the limiting component includes a top slide rail and a bottom slide rail, and the double-headed rod is slidably engaged in the grooves on the opposite surfaces of the top and bottom slide rails.

[0015] Preferably, the bottom of the pressing mechanism is integrally connected to one side of the top slide rail and the bottom slide rail, a secondary gear is fixedly connected to the outer surface of the double-headed rod, a first bent rod is fixedly connected to one side of the bottom of the secondary gear, and an electric welding pen is fixedly connected to one side of the bottom of the first bent rod.

[0016] Preferably, the pressing mechanism has a cavity at the top of the bottom slide rail, and the main gear is fixedly connected to the bottom output shaft surface of the motor.

[0017] Preferably, the outer surface of the main gear is an annular fixed meshing secondary gear, and the outer surface of the secondary gear is fixed with a core limiting sleeve.

[0018] To further explain the above, the limiting sleeve that meshes with the outer surface of the auxiliary gear during the rotation of the main gear is used to limit the movement of the limiting component.

[0019] During the process of the auxiliary gear driving the first curved rod and the welding pen to rotate in a ring between the inner and outer slide rails, the welding pen moves in a circular motion by sliding and engaging the inner and outer slide rails in the grooves through the round-headed slide rods on both sides of the ball head.

[0020] The placement of four welding pens at the connection between the housing and the flange ring facilitates the direct welding of the connection between the housing and the flange ring by the main gear driving the auxiliary gear in one circular motion.

[0021] Preferably, the bottom of the pressing mechanism has a threaded groove on the bottom surface of the bottom slide rail, the surface of the threaded groove is threaded with a threaded ring, the outer surface of the threaded ring is fixedly connected to the second bent rod in an annular shape, and the bottom of the second bent rod is fixedly connected with a positioning ring sleeve.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] When welding the end caps and flanges, the worker lowers the entire pressing mechanism by using the first electric telescopic component. During the descent, the bottom arc rod drives the inner slide rail to descend. Simultaneously, the worker activates the second electric telescopic component to extend and retract, causing the outer slide rail to descend as well. This allows the bottom of the inclined welding pen, held between the inner and outer slide rails, to directly contact the connection between the end cap and the flange ring. Then, the motor is activated, causing the bottom output shaft to drive the main gear to rotate. At the same time, this drives the secondary gear to rotate within the grooves of the top and bottom slide rails, simultaneously causing the welding pen to rotate between the inner and outer slide rails. This allows the bottom of the welding pen to weld between the end cap and the flange ring. This method effectively reduces the need for extensive manual labor and minimizes the low work efficiency when there are many workpieces. It can also be used for single workpieces, improving the overall work efficiency.

[0025] As the pressing mechanism presses down, the bottom rubber pad of the pressing mechanism presses against the top of the casing to fix it. Then, the operator rotates the threaded ring, causing the threaded ring at the bottom of the pressing mechanism to descend. As the threaded ring descends, it also causes the second bent rod and the positioning ring to descend and fit against the top outer edge of the casing, effectively stabilizing the casing and preventing displacement during the subsequent welding process.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 7 As shown, the present invention provides a high-precision equipment for processing graphite heat exchanger heads, including a pressing mechanism 1, a motor 2 fixedly connected to the top of the pressing mechanism 1, a switch button 3 provided on the top of the motor 2, four support components 6 fixedly connected in a ring on the outer surface near the top of the pressing mechanism 1, and a sealing shell 4 movably connected to the bottom of the pressing mechanism 1 through an arc-shaped rubber pad, and a flange ring 5 welded to the outer edge of the sealing shell 4.

[0036] The second electric telescopic component 7 is fixedly connected to one side of the outer edge of the support component 6, and the bottom of the second electric telescopic component 7 is telescopically connected to the outer slide rail 15.

[0037] A first electric telescopic component 9 is connected to a pivot on one side of the four support components 6. A suction cup is fixedly connected to the bottom of the first electric telescopic component 9. The height of the pressing mechanism 1 can be adjusted by raising and lowering the bottom of the first electric telescopic component 9. The support components 6 and the first electric telescopic component 9 are connected in an L-shape to provide main support to the ground.

[0038] A limit component 13 and a threaded ring 12 are sequentially installed from top to bottom at the bottom two-thirds of the pressing mechanism 1;

[0039] An arc rod is annularly connected to the top outer surface of the threaded ring 12 at the bottom of the pressing mechanism 1. An inner slide rail 8 is fixedly connected to one side of the arc rod at the bottom of the pressing mechanism 1. A ball head 16 is slidably engaged in the outer groove of the inner slide rail 8. The other side of the ball head 16 is slidably engaged in the outer slide rail 15 through the groove. A welding pen 10 is fixedly connected to the ball head 16. The bottom of the welding pen 10 is located at the connection between the sealing part 4 and the flange ring part 5. The ball head 16 includes a round-headed slide rod 161. The inner wall of the round-headed slide rod 161 is inclined.

[0040] In use, when welding the end cap and flange, the operator first places the end cap 4 at the bottom of the pressing mechanism 1, then places the flange ring 5 on top of the end cap 4. The operator then lowers the pressing mechanism 1 as a whole by using the first electric telescopic component 9. During the descent, the bottom arc rod drives the inner slide rail 8 to descend. Simultaneously, the operator activates the second electric telescopic component 7 to extend and retract, causing the outer slide rail 15 to descend as well. This ensures that the bottom of the inclined welding torch 10, held between the inner and outer slide rails 8, is directly positioned at the connection between the end cap 4 and the flange ring 5. Then, the motor 2 is started to rotate the main gear 24 driven by the bottom output shaft. At the same time, the auxiliary gear 23 rotates in the groove of the top slide rail 21 and the bottom slide rail 22. Simultaneously, the welding pen 10 rotates between the inner slide rail 8 and the outer slide rail 15, so that the bottom of the welding pen 10 welds between the sealing part 4 and the flange ring part 5. This effectively reduces the need for direct welding of the entire workpiece by the pressing mechanism 1 when there are many workpieces, thus reducing the need for workers to consume a lot of labor and causing low work efficiency. At the same time, it can also be used when there are only a few workpieces, which helps to improve the overall work level.

[0041] like Figures 2 to 7 As shown, the bottom of the pressing mechanism 1 is fixedly connected to the ring 17 on the top surface of the limiting component 13. The inner wall of the annular groove on the outer surface of the ring 17 is slidably engaged with the L rod 18. The bottom of the L rod 18 is fixedly connected to the limiting tooth sleeve 19.

[0042] The limiting component 13 includes a top slide rail 21 and a bottom slide rail 22. The double-headed rod 20 is slidably engaged in the grooves on the opposite surfaces of the top slide rail 21 and the bottom slide rail 22. One side of the top slide rail 21 and the bottom slide rail 22 connects the bottom of the pressing mechanism 1 as a whole. A secondary gear 23 is fixedly connected to the outer surface of the double-headed rod 20. A first bent rod 14 is fixedly connected to one side of the bottom of the secondary gear 23. A welding pen 10 is fixedly connected to one side of the bottom of the first bent rod 14.

[0043] The lowering mechanism 1 has a cavity at the top of the bottom slide rail 22. The main gear 24 is fixedly connected to the bottom output shaft surface of the motor 2. The outer surface of the main gear 24 is ring-shaped and fixedly meshes with the secondary gear 23. The outer surface of the secondary gear 23 is fixed with the core limiting sleeve 19.

[0044] When in use, when the output shaft of motor 2 drives the main gear 24 to rotate, the main gear 24 will drive the secondary gear 23 and the limiting sleeve 19 to rotate together. When the limiting sleeve 19 rotates, the top of the L rod 18 will move in a circular motion within the groove on the outer surface of the ring 17. When the secondary gear 23 is driven by the main gear 24, it will drive the two sides of the double-headed rod 20 to move in a circular motion within the grooves of the top slide rail 21 and the bottom slide rail 22.

[0045] While the auxiliary gear 23 is making circular motion, it drives the first bent rod 14 and the welding pen 10 to rotate, so that the bottom of the welding pen 10 can directly weld the casing 4 and the flange ring 5 in a ring.

[0046] To further explain the above, the limiting sleeve 19 that meshes with the outer surface of the auxiliary gear 23 during the rotation of the main gear 24 serves to limit the limiting component 13.

[0047] During the circular rotation of the first bent rod 14 and the welding pen 10 between the inner slide rail 8 and the outer slide rail 15 driven by the secondary gear 23, the welding pen 10 makes circular motion by sliding and engaging the inner slide rail 8 and the outer slide rail 15 grooves through the round-headed slide rods 161 on both sides of the ball head 16.

[0048] The four welding pens 10 located at the connection between the housing 4 and the flange ring 5 are designed to facilitate the direct welding of the connection between the housing 4 and the flange ring 5 by the main gear 24 driving the auxiliary gear 23 to complete one revolution.

[0049] like Figures 1 to 4 As shown, the bottom of the pressing mechanism 1 is provided with a threaded groove 101 on the bottom surface of the bottom slide rail 22. The surface of the threaded groove 101 is threadedly connected to a threaded ring 12. The outer surface of the threaded ring 12 is fixedly connected to the second bent rod 121 in an annular shape. The bottom of the second bent rod 121 is fixedly connected to a positioning ring sleeve 11.

[0050] During use, as the pressing mechanism 1 presses down, the bottom rubber pad of the pressing mechanism 1 will press against the top of the sealing shell 4 for fixation. Then, the operator rotates the threaded ring 12, causing the threaded ring 12 to descend at the bottom of the pressing mechanism 1. As the threaded ring 12 descends, it also drives the second bent rod 121 and the positioning ring sleeve 11 to descend and adhere to the top outer edge of the sealing shell 4, effectively stabilizing the sealing shell 4 as a whole and preventing displacement during the subsequent electric welding process.
