Description

Technical Field

[0001] The present application belongs to the technical field of pipe brackets, and in particular, relates to a servo-driven roller rack device. Background Art

[0002] When processing pipe workpieces, it is necessary to clamp and fix the pipe fittings of the clamping and fixing assembly. For some processing procedures, the pipe fittings do not need to be fixed, while some need to fix the pipe fittings and rotate the pipe fittings at the same time. For example, welding, weld detection and other processing procedures all require the pipe fittings to be able to rotate. The existing clamping assemblies can also clamp and rotate the pipe fittings, but the clamping assemblies are located at both ends of the pipe, clamping the two end surfaces of the pipe, and then the motor drives it to rotate. For long pipe fittings, the clamping assemblies on both sides of the pipe fittings are set as far apart as the length of the pipe fittings. This design is not suitable. Therefore, based on this, an improved technology with high practicality and capable of clamping pipe fittings and clamping pipe fittings and rotating the pipe fittings at the same time is proposed. Utility Model Content

[0005] A servo-driven roller frame device comprises a machine platform, wherein at least two sets of support components are arranged on the machine platform, the two sets of support components support one pipe fitting, and are arranged accordingly according to the number of workstations, and the two sets of support components are arranged in parallel and at intervals;

[0006] Each support assembly includes a frame, a driving shaft, a driving wheel, a driven wheel, a servo motor, and an elastic clamping cylinder. The driving shaft is provided with two and rotates on the frame. The driving wheel and the driven wheel are respectively installed on the two driving shafts. The servo motor is installed on the other side of the frame. The output end of the servo motor is connected to the driving shaft of the driving wheel to drive the driving wheel to rotate. There is a gap between the driving wheel and the driven wheel.

[0007] The elastic clamping cylinder is located on one side of the frame. The elastic clamping cylinder can adjust the clamping force according to actual needs. A clamping head is provided at the movable end of the elastic clamping cylinder. The clamping head is located between the driving wheel and the driven wheel. The clamping head is used to clamp the pipe fittings between the driving wheel and the driven wheel.

[0008] Furthermore, the servo motor is also installed with a right-angle reducer, and a mounting port for installing the right-angle reducer is provided on the machine platform. The right-angle reducer is easy to install and saves space.

[0009] Furthermore, a protective cover is provided on one side of the movable end of the elastic clamping cylinder to protect the clamping head. An upper arc-shaped recess matching the shape of the pipe fitting is provided below the protective cover. The protective cover has a protective function, and the pipe fitting is located below the upper arc-shaped recess.

[0010] Furthermore, the clamping head is composed of two rubber-coated wheels arranged in parallel front and back, and is rotatably mounted on the movable end of the elastic clamping cylinder. Because it is driven by a servo motor, the rubber-coated wheel can effectively play an insulating effect, and the rubber-coated wheel has high strength and durability.

[0011] Furthermore, a lower arc-shaped recess is provided on the frame, and the lower arc-shaped recess corresponds to the upper arc-shaped recess up and down, and the pipe fitting is located between the lower arc-shaped recess and the upper arc-shaped recess.

[0012] The beneficial effects of the utility model are:

[0013] When it is used only as a clamping support component, the servo motor is not started, and the pipe fittings are clamped by the clamping head, so that the pipe fittings can be clamped and fixed;

[0014] When the pipe needs to be clamped and driven to rotate, the servo motor starts to drive the driving wheel to rotate, thereby driving the pipe to rotate;

[0015] In summary, the utility model has multiple functions and meets different usage requirements. It can be adjusted according to the clamping force required by the pipe fitting to achieve the expected clamping force.

[0016] The load-bearing capacity can also be adjusted according to the size of the pipe fittings, and the coaxiality height can be adjusted according to the outer diameter of the pipe fittings. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example

[0029] The present embodiment provides a servo-driven roller frame device, including a machine platform 1, on which at least two groups of support components 2 are arranged, the two groups of support components 2 support a pipe fitting, and are arranged accordingly according to the number of workstations, and the two groups of support components 2 are arranged in parallel and at intervals;

[0030] Each support assembly 2 includes a frame 3, a driving shaft 4, a driving wheel 5, a driven wheel 6, a servo motor 7, and an elastic clamping cylinder 8. The frame 3 is mounted on the machine table 1. Two driving shafts 4 are provided and rotate on the frame 3. The driving shafts 4 are arranged side by side and mounted on one side of the frame 3. The driving wheel 5 and the driven wheel 6 are respectively mounted on the two driving shafts 4. The servo motor 7 is mounted on the other side of the frame 3. The output end of the servo motor 7 is connected to the driving shaft 4 of the driving wheel 5 to drive the driving wheel 5 to rotate. There is a gap between the driving wheel 5 and the driven wheel 6.

[0031] The elastic clamping cylinder 8 is located on one side of the frame 3. A clamping head 9 is provided at the movable end of the elastic clamping cylinder 8. The clamping head 9 is located between the driving wheel 5 and the driven wheel 6. The clamping head 9 of the elastic clamping cylinder 8 can move up and down, thereby driving the clamping head 9 to clamp the pipe between the driving wheel 5 and the driven wheel 6.

[0032] The servo motor 7 is also installed with a right-angle reducer 10. The machine platform 1 is provided with an installation opening 11 for installing the right-angle reducer 10. The hidden installation method effectively protects the servo motor, avoids damage to the servo motor and the reducer, and saves installation space.

[0033] A protective cover 12 is provided on one side of the movable end of the elastic clamping cylinder 8 to protect the reducer and the servo motor, while protecting the clamping head 9 inside. An upper arc-shaped recess 13 matching the shape of the pipe fitting is provided below the protective cover 12. The protective cover 12 has a protective function, and the servo motor and the reducer play a certain protective role. The pipe fitting is below the upper arc-shaped recess 13.

[0034] The clamping head 9 is composed of two rubber-coated wheels arranged in parallel front and back. Because it is driven by a servo motor, the rubber-coated wheels can effectively play an insulating role. A connecting block is provided on the clamping head. Connecting the rubber-coated wheels can increase the friction when the pipe is rolling and effectively protect the surface of the pipe from being scratched. The connecting block is rotatably installed on the active end of the elastic clamping cylinder 8. The rubber-coated wheel 9 has high strength and durability. The outer ring is made of polyurethane, which is elastic and prevents scratches on the surface of the workpiece.

[0035] A lower arc-shaped recess 14 is provided on the frame 3, and the lower arc-shaped recess 14 corresponds to the upper arc-shaped recess 13 up and down. The pipe fitting is located between the lower arc-shaped recess 14 and the upper arc-shaped recess 13, and the edges of the lower arc-shaped recess 14 and the upper arc-shaped recess 13 have an arc-shaped smooth transition. The upper and lower arc-shaped recesses can prevent the pipe fitting from directly contacting the frame and damaging the surface of the pipe fitting; they can also indirectly protect the pipe fitting from falling when subjected to external force, support the pipe fitting, play an effective protective role, and improve the safety factor.

[0036] When the utility model product is implemented:

[0037] Open the movable end of the elastic clamping cylinder, even if the clamping head is away from the driving wheel, place the pipe between the driving wheel and the driven wheel, and the clamping head presses down to compact the pipe. Then the servo motor starts to drive the driving wheel to rotate, and the pipe is driven. The driven wheel rotates with the rotation of the pipe, and the rubber-coated wheel also rotates, so that the pipe can be clamped. At the same time, the servo motor drives it to rotate, and related processes can be carried out, such as welding, pipe inspection, cutting and other processes.

[0038] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
