Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and in particular to a feeding mechanism for a pressure gauge welding machine. Background Technology

[0002] A pressure gauge is an instrument used to measure and display pressure, and it is widely used in industries such as industry, medicine, aviation, and automobiles. Pressure gauges sense pressure changes through internal sensitive elements (such as Bourdon tubes, diaphragms, bellows, etc.) and convert this information into a pointer or digital display so that users can read the pressure value.

[0003] Pressure gauges, as widely used pressure measuring instruments, offer numerous advantages, making them highly favored in various applications. For example, Chinese Patent Publication No. CN210817964U discloses a feeding mechanism for a reciprocating laser welding machine. This mechanism includes a work platform with casters fixedly mounted on its lower surface. Each caster has a locking mechanism inside. A lifting button is fixedly mounted on the front surface of the work platform. A push rod motor is fixedly mounted on the upper surface of the work platform, with an electric push rod fixedly mounted on its upper end. A work box is fixedly mounted on the upper end of the electric push rod, and a feeding plate is movably mounted on the upper end of the work box. This feeding mechanism for the reciprocating laser welding machine, equipped with a hand crank, a drive wheel, and a working belt, allows for reciprocating movement of the feeding mechanism by cranking the hand crank clockwise or counterclockwise. Furthermore, by using multiple sets of push rod motors and electric push rods, the height of the feeding plate off the ground can be easily adjusted, significantly increasing work efficiency, extending service life, and enhancing practicality.

[0004] Currently, when welding machines are performing batch welding, pressure gauges need to be continuously fed in order to ensure welding efficiency. Since the specifications of pressure gauges are different, the feeding structure also needs to be easily replaced according to the actual specifications of the pressure gauges in order to ensure stable processing of different models and specifications when processing pressure gauges. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a feeding mechanism for a pressure gauge welding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a feeding mechanism for a pressure gauge welding machine, including an operating table. A motor is installed on the top of the operating table. The lower end of the motor is fixedly assembled to the surface of the operating table by screws. A drive shaft is installed inside the motor. A central disk is fixedly installed at the end of the shaft. A forked plate is distributed on the outer ring wall of the central disk. The forked plate has several forked segments. The connection position between the forked plate and the central disk is fixed by welding.

[0008] A storage seat is provided above the end of the bifurcation section of the bifurcation plate that is away from the central disk, and a pressure gauge is inserted inside the storage seat;

[0009] An inner sleeve is provided through the inside of the forked plate. The inner sleeve is fixed to the forked plate by welding. A threaded post is welded to the lower end of the seat. The surface of the threaded post is slidably sleeved with the inside of the inner sleeve. The lower end of the threaded post is threadedly connected to a threaded sleeve. The upper end of the threaded sleeve is tightly attached to the end face of the inner sleeve. Several knobs are distributed on the outer ring wall of the threaded sleeve. One end of each knob is welded to the surface of the threaded sleeve.

[0010] In detail, the surface of the bifurcation section of the bifurcation plate is provided with an alignment groove, and an alignment block is fixed at the lower end of the placement seat. The alignment block slides and inserts into the interior of the alignment groove.

[0011] In detail, the upper end of the operating table is provided with a slide rail sub-slide rail, the lower end of the slide rail sub-slide rail is fixedly assembled to the surface of the operating table by screws, a slide rail sub-slide block is slidably provided on the surface of the slide rail sub-slide rail, and anti-detachment plates are fixed on both sides of the slide rail sub-slide rail.

[0012] In detail, the upper end of the slide rail secondary slide block one is fixed with the slide rail secondary slide rail two, the slide rail secondary slide block two is slidably disposed on the surface of the slide rail secondary slide rail two, and the two ends of the slide rail secondary slide rail two are respectively fixed with anti-detachment plates two.

[0013] In detail, the lower end of the slide rail secondary slide rail is fixed with a support rod, and the upper end of the operating table is fixed with a slide rail. The surface of the support rod is slidably and tightly attached to the inner wall of the slide rail.

[0014] In detail, a cylinder is fixed to the upper end of the slide rail secondary slide block two, and a piston rod for extension and retraction is provided inside the cylinder.

[0015] In detail, a support plate is fixed to the end of the piston rod of the cylinder, and a welding head is provided through the end of the support plate away from the cylinder. A welding machine is also fixed to the upper end of the support plate, and the end of the welding head is connected to the terminal of the welding machine through a power transmission line.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. When welding pressure gauges is required, a welding machine with a welding head can be used to weld the pressure gauges. According to the specifications of the pressure gauge batch, a suitable mounting base is selected and placed at the end of the bifurcation section of the bifurcation plate. The alignment block at the lower end of the mounting base slides into the alignment groove on the bifurcation section, which can achieve rapid positioning of the mounting base and the bifurcation section. At the same time, the threaded column and the inner sleeve are slidably fitted together. Through the threaded connection between the threaded sleeve and the threaded column, the mounting base and the bifurcation section can be stably installed. The rotation of the motor drives the shaft and rotates the central plate, so that the pressure gauges and welding heads to be welded can be continuously positioned in the bifurcation sections of the bifurcation plate.

[0018] 2. By sliding the first slide block on the first slide block, the welding head can move left and right. By sliding the second slide block on the second slide block, the welding head can move back and forth. Since the second slide block extends outward too much, it can be supported by a support rod. The support rod can also slide on the slide rail, which can cooperate to make left and right displacement. By extending and retracting the piston rod of the cylinder, the welding head can move up and down. Thus, the welding head can be made to contact the pressure gauge for welding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A feeding mechanism for a pressure gauge welding machine includes an operating table 1. A motor 11 is mounted on top of the operating table 1. The lower end of the motor 11 is fixedly assembled to the surface of the operating table 1 by screws. A drive shaft is provided inside the motor 11. A central disk 12 is fixedly mounted at the end of the shaft. A forked plate 13 is distributed on the outer ring wall of the central disk 12. The forked plate 13 has several forked sections. The connection position between the forked plate 13 and the central disk 12 is fixed by welding. The motor 11 is a servo motor. A servo motor is an electric motor that can precisely control position, speed and torque. It is widely used in industrial automation, robotics, CNC machine tools, aerospace and other fields. Servo motors are usually used in conjunction with servo drives to form a closed-loop control system to achieve high-precision motion control.

[0026] A storage seat 14 is provided above the end of the forked section of the forked plate 13 that is away from the central plate 12, and a pressure gauge 15 is inserted inside the storage seat 14.

[0027] An inner sleeve 16 is provided through the inside of the forked plate 13. The inner sleeve 16 is fixed to the forked plate 13 by welding. A threaded post 18 is welded to the lower end of the seat 14. The surface of the threaded post 18 is slidably sleeved with the inside of the inner sleeve 16. A threaded sleeve 17 is threadedly connected to the lower end of the threaded post 18. The upper end of the threaded sleeve 17 is tightly attached to the end face of the inner sleeve 16. Several knobs 19 are distributed on the outer ring wall of the threaded sleeve 17. One end of the knob 19 is welded to the surface of the threaded sleeve 17.

[0028] It should be further explained that the surface of the bifurcation section of the bifurcation plate 13 is provided with an alignment groove 2, and the lower end of the storage seat 14 is fixed with an alignment block 21. The alignment block 21 slides and inserts into the alignment groove 2, which can realize the quick positioning and docking of the storage seat 14 and the bifurcation plate 13.

[0029] It should be further explained that the upper end of the operating table 1 is provided with a slide rail sub-slide rail 3, the lower end of the slide rail sub-slide rail 3 is fixedly assembled with the surface of the operating table 1 by screws, the surface of the slide rail sub-slide rail 3 is slidably provided with a slide rail sub-slide block 31, and anti-detachment plates 32 are fixed on both sides of the slide rail sub-slide rail 3, which can realize the stable left and right movement of the welding head 41.

[0030] It should be further explained that the upper end of the slide rail secondary slide block 31 is fixed with the slide rail secondary slide rail 2 33, the surface of the slide rail secondary slide rail 2 33 is slidably provided with the slide rail secondary slide block 2 34, and the two ends of the slide rail secondary slide rail 2 33 are respectively fixed with the anti-detachment plate 2 35, which can realize the stable back and forth movement of the welding head 41.

[0031] It should be further explained that the lower end of the slide rail 2 33 is fixed with a support rod 36, and the upper end of the operating table 1 is fixed with a slide rail 37. The surface of the support rod 36 is slidably and tightly attached to the inner wall of the slide rail 37. Since the slide rail 2 33 extends outward too much, it can be assisted by the support rod 36. The support rod 36 can also slide on the slide rail 37, and can be moved left and right in coordination.

[0032] It should be further noted that a cylinder 38 is fixed at the upper end of the slide rail secondary slide block 34. The cylinder 38 has a piston rod for extension and retraction inside, which can realize the stable up and down movement of the welding head 41.

[0033] It should be further explained that a support plate 4 is fixed to the end of the piston rod of the cylinder 38. A welding head 41 is provided through the end of the support plate 4 away from the cylinder 38. A welding machine 42 is also fixed to the upper end of the support plate 4. The end of the welding head 41 is connected to the terminal of the welding machine 42 through a power transmission line and fixed.

[0034] The guide rail pair structure is a sliding friction guide rail pair, which typically consists of a straight guide rail and a slider that slides on it. The principle is that when the slider moves on the guide rail, sliding friction is generated between the two. To reduce frictional resistance and wear, lubricating oil or self-lubricating materials are usually applied between the guide rail and the slider.

[0035] Working method: When welding is required for pressure gauge 15, welding machine 42 and welding head 41 can be used to weld the welding points of pressure gauge 15. According to the specifications of the batch of pressure gauge 15, a suitable seat 14 is selected and placed at the end of the bifurcation section of bifurcation plate 13. The alignment block 21 at the lower end of seat 14 slides into the alignment groove 2 on the bifurcation section, which can realize the rapid positioning of seat 14 and bifurcation section. At the same time, threaded column 18 and inner sleeve 16 are slidably connected. Through the threaded sleeve 17 and threaded column 18 threaded connection, the seat 14 and bifurcation section can be stably installed. The rotation of motor 11 drives its shaft and makes the center plate 12 rotate. Thus, the bifurcation sections of bifurcation plate 13 can continuously position the pressure gauge 15 to be welded and the welding head 41.

[0036] The welding head 41 can move left and right by sliding the slide block 31 on the slide block 3. The welding head 41 can move back and forth by sliding the slide block 34 on the slide block 33. Since the slide block 33 extends outward too much, it can be supported by the support rod 36. The support rod 36 can slide on the slide rail 37 and can move left and right. The welding head 41 can move up and down by extending and retracting the piston rod of the cylinder 38. Thus, the welding head 41 can be made to contact the pressure gauge 15 for welding.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
