Description

Technical Field

[0001] This utility model relates to the field of steel cylinder production technology, specifically a three-dimensional steel cylinder typing device. Background Technology

[0002] A gas cylinder is a sealed metal container used to store and transport high-pressure or liquefied gases. It is typically made of high-strength steel and is pressure- and corrosion-resistant. Its structure includes the cylinder body, valves, safety devices, and other components. The cylinder body is mostly cylindrical and undergoes precision welding and heat treatment to ensure its pressure-bearing capacity. Gas cylinders are widely used in industrial, medical, and scientific research fields, such as storing industrial gases like oxygen, nitrogen, and argon, or liquefied petroleum gas (LPG) and carbon dioxide. Gas types are often distinguished by color and labels; for example, blue represents oxygen, and green represents argon. Gas cylinders require marking and coding during production.

[0003] For example, CN211968922U discloses a precision cylinder coding device, which includes a frame with a conveyor drive shaft, a conveyor driven shaft, a conveyor motor, and two transmission chains. A rotating roller is positioned between the two transmission chains, and the rotating roller is equipped with a rotating motor and multiple lifting rods, each with an infrared emitter. A gantry frame is mounted on the frame, and a lifting cylinder, a mounting plate, and a spray nozzle are mounted on the top surface of the gantry frame. Moving cylinders are mounted on both inner sides of the gantry frame, and a rotating plate is mounted on each moving cylinder via a moving plate. Servo motors and clamping devices are respectively mounted on the two sides of the rotating plate. Infrared sensors are mounted on both sides of the gantry frame. This invention not only improves work efficiency but also has advantages such as high coding accuracy, low labor intensity, high stability, ease of use, wide applicability, long service life, and high user comfort.

[0004] However, in the above technology, the typing mechanism is fixed on the gantry, which means that the typing device can only type on a specific position of the cylinder, making it impossible to type on the cylinder body from all angles. Therefore, the market urgently needs to develop a three-dimensional cylinder typing device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a three-dimensional cylinder typing device to solve the problem mentioned in the background art that the typing mechanism is fixed on the gantry, so that the typing device can only type on a specific position of the cylinder, resulting in the cylinder body not being able to be typed from all directions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional cylinder typing device, comprising a circular base plate, an annular rotating seat rotatably connected to the upper end of the circular base plate, six three-grip chucks rotatably connected to the upper end of the annular rotating seat in an annular array, six driving devices fixedly connected to the lower end of the annular rotating seat in an annular array, a support column fixedly connected to the middle of the rear end of the circular base plate, a vertical linear guide rail provided at the front end of the support column, and a typing device being lifted and lowered at the front end of the linear guide rail.

[0008] Preferably, the gear on the first servo motor is inserted into the internal gear ring and meshes with the teeth of the internal gear ring.

[0009] Preferably, the upper end face of the annular rotating seat is fixedly connected with six limiting tubes in an annular array, and the lower ends of the six limiting tubes are respectively inserted into the interior of six driving devices, and a second servo motor is fixedly installed inside the driving device.

[0010] Preferably, each of the three-grip chucks has a rotating shaft fixedly connected to the middle of its lower end, and the lower ends of the six rotating shafts extend through the middle of the six limiting tubes into the interior of the six driving devices and are fixedly connected to the output shaft of the second servo motor.

[0011] Preferably, the linear guide rail is fixedly connected to the front end face of the support column, and the rear end face of the typing device is fixedly connected to a linear slider.

[0012] Preferably, the rear linear slider of the typing device is slidably connected to the vertical linear guide rail.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the three-grip chuck rotation and the typing device lifting and lowering are coordinated to enable the typing device to cover any position on the outer wall of the cylinder, realizing true three-dimensional typing and solving the problem that traditional fixed typing devices cannot type in all directions.

[0015] (2) In this utility model, by setting a rotatable ring rotating seat in conjunction with multiple three-grip chucks, continuous flow operation of steel cylinders is realized, which greatly improves production efficiency. At the same time, the six workstations are used in a cycle to reduce equipment idle time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a three-dimensional cylinder typing device, comprising a circular base plate 1, an annular rotating seat 2 rotatably connected to the upper end of the circular base plate 1, and a slewing bearing 101 rotatably connecting the upper end of the circular base plate 1 and the lower end of the annular rotating seat 2. Six three-grip chucks 3 are rotatably connected in an annular array to the upper end of the annular rotating seat 2. Each three-grip chuck 3 is rotated to the front end one by one by the annular rotating seat 2. Cylinders are manually placed vertically on the three-grip chucks 3 that have been rotated to the front end, and the three-grip chucks 3 clamp and fix the bottom of the cylinder. A support column 4 is fixedly connected to the middle of the rear end of the circular base plate 1. A vertical linear guide rail 401 is provided at the front end of the support column 4. A typing device 5 is vertically connected to the front end of the linear guide rail 401. The guide rail 401 is fixedly connected to the front end face of the support column 4. The rear end face of the typing device 5 is fixedly connected to a linear slider 501. The rear end linear slider 501 of the typing device 5 is slidably connected to the vertical linear guide rail 401. The linear slider 501 slides on the vertical linear guide rail 401 to drive the typing device 5 to adjust its height. When the annular rotating seat 2 rotates intermittently, the clamped cylinders are rotated one by one to the rear end and located at the front end of the typing device 5. The typing device 5 types on the outer wall of the cylinder. At the same time, the rotation of the three-grip chuck 3, in conjunction with the height adjustment of the typing device 5, facilitates all-round typing on the outer wall of the cylinder. When the typed cylinder is rotated intermittently, it returns to the front end, and the personnel can unload the cylinder and put the cylinder to be typed back.

[0024] Please see Figure 2 and Figure 3 An internal gear ring 201 is fixedly connected to the middle of the annular rotating seat 2. A first servo motor 102 is fixedly connected to the middle of the upper end face of the circular base plate 1. A gear 103 is fixedly connected to the output shaft of the first servo motor 102. The gear 103 on the first servo motor 102 is inserted into the internal gear ring 201 and meshes with the teeth of the internal gear ring 201. The internal gear ring 201 is driven to rotate intermittently by the first servo motor 102 through the gear 103, thereby causing the internal gear ring 201 to drive the annular rotating seat 2 to rotate intermittently.

[0025] Please see Figure 3 and Figure 4 The lower end face of the annular rotating seat 2 is fixedly connected to six driving devices 203 in an annular array, and the upper end face of the annular rotating seat 2 is fixedly connected to six limiting tubes 202 in an annular array. The lower ends of the six limiting tubes 202 are respectively inserted into the six driving devices 203. A second servo motor 204 is fixedly installed inside the driving device 203. A rotating shaft 301 is fixedly connected to the middle of the lower end of each three-grip chuck 3. The lower ends of the six rotating shafts 301 pass through the middle of the six limiting tubes 202 and extend into the six driving devices 203 respectively, and are fixedly connected to the output shaft of the second servo motor 204. The three-grip chuck 3, which grips the steel cylinder, is driven by the second servo motor 204 to rotate and adjust the position of the steel cylinder when it is being typed.

[0026] Working Principle: In operation, the first servo motor 102 drives the gear 103 to mesh with the internal gear ring 201, causing the annular rotating seat 2 to rotate intermittently, rotating the empty three-grip chucks 3 one by one to the operating station. The operator places the cylinder to be typed vertically onto the three-grip chuck 3 at the current station, where the chuck 3 automatically clamps and secures the bottom of the cylinder. When the annular rotating seat 2 rotates again, the three-grip chuck 3 holding the cylinder is rotated to the typing station. At this time, the second servo motor 204 drives the three-grip chuck 3 and the cylinder to rotate around the axis via the rotating shaft 301. Simultaneously, the typing device 5 moves up and down along the vertical linear guide rail 401 via the linear slider 501. The coordinated action of both allows the typing head to be precisely positioned at any position on the outer wall of the cylinder, achieving omnidirectional typing on the cylinder surface in both the circumferential and axial directions. After the typed cylinder returns to the operating station with the annular rotating seat 2, the operator unloads the finished product and replaces it with a new cylinder. The six stations operate in a cyclical manner to achieve continuous production.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
