Description

Technical Field

[0001] This utility model is a rotary clamp for grinding and polishing the outer surface of seamless tubes, belonging to the field of seamless tube grinding and polishing technology. Background Technology

[0002] During the production of seamless tubes, after large-diameter cleaning and annealing, the outer surface needs to be cleaned and polished to improve its quality. Currently, professional polishing tools are typically used to polish the outer surface of steel tubes. Before polishing, the seamless tube needs to be clamped and fixed using appropriate fixtures. Existing fixtures usually clamp the outer surface of the seamless tube, which prevents a portion of the outer surface from being directly polished, requiring secondary operations. This makes polishing time-consuming, labor-intensive, inefficient, and impractical. There is an urgent need for a rotary fixture for polishing the outer surface of seamless tubes to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary clamp for grinding and polishing the outer surface of seamless tubes, so as to solve the problems mentioned in the background art. This utility model has a reasonable structure. The moving seat is driven by a drive motor to move, thereby pushing the extrusion fixing seat and forming an extrusion fixing on the inner wall of the seamless tube, thereby fixing the end of the seamless tube. It is simple and convenient to use, has a good fixing effect, and is highly practical.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a rotary fixture for grinding and polishing the outer surface of seamless tubes, comprising a base, a rotating seat, a support frame, a drive motor, a threaded column, a movable seat, a mounting seat, a pressing and fixing seat, and a positioning slide rod. The rotating seat is provided on the right end face of the base, the support frame is provided on the right side of the base, the drive motor is mounted on the left end face of the base, the threaded column is provided on the left side of the drive motor, the movable seat is provided on the left side of the drive motor, the mounting seat is provided on the left side of the base, the pressing and fixing seat is provided on the left side of the mounting seat, and the positioning slide rod is clamped on the upper end face of the pressing and fixing seat.

[0005] Furthermore, a rotating shaft is fitted onto the right end face of the rotating base, and the rotating shaft is connected to the output end of an external servo motor. The support frame is rotatably connected to the rotating base through a bearing connector.

[0006] Furthermore, the movable seat is generally shaped like a cone, narrower on the left and wider on the right. A threaded seat is embedded on the right end face of the movable seat, and the threaded seat meshes with the threaded post. The inner side of the compression fixing seat abuts against the outer side of the movable seat.

[0007] Furthermore, a limiting groove is provided on the right end face of the movable seat, and limiting plates are provided above and below the drive motor. The limiting plates are slidably engaged with the movable seat through the limiting groove.

[0008] Furthermore, a connecting frame is provided on the right end face of the mounting base, and the mounting base is fixedly connected to the base through the connecting frame. A baffle is provided on the left end face of the mounting base.

[0009] Furthermore, several sets of the extrusion fixing seat and the mounting seat are provided with equal specifications. The outer side of the extrusion fixing seat is bonded with an anti-slip pad. The extrusion fixing seat is slidably connected to the baffle through a positioning slide rod.

[0010] Furthermore, a return spring is sleeved on the annular side of the positioning slide rod, and the two ends of the return spring abut against the upper end face of the compression fixing seat and the lower end face of the baffle, respectively.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a rotary clamp for grinding and polishing the outer surface of seamless tubes. Because this utility model adds a pressing fixed seat, a movable seat, a positioning slide rod, and a threaded column, the user places the end of the seamless tube on the outside of the pressing fixed seat, and then operates an external controller to control the drive motor to start. The output end of the drive motor drives the threaded column to rotate through the motor shaft. Since the threaded column and the threaded seat mesh with each other, the rotation of the threaded column can drive the movable seat to move along the axial direction. Since the outer surface of the movable seat abuts against the inner side of the pressing fixed seat, the movement of the movable seat causes the pressing fixed seat to unfold outward along the surface of the positioning slide rod, and the outer surface of the pressing fixed seat abuts against the inner wall of the end of the seamless tube through the anti-slip pad, thereby fixing the end of the seamless tube.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Please see Figures 1-4 This utility model provides a technical solution: a rotary clamp for grinding and polishing the outer surface of seamless tubes, including a base 1, a rotating seat 2, a support frame 3, a drive motor 4, a threaded column 5, a movable seat 6, a mounting seat 7, a pressing and fixing seat 8, and a positioning slide rod 9. The rotating seat 2 is provided on the right end face of the base 1, the support frame 3 is provided on the right side of the base 1, the drive motor 4 is installed on the left end face of the base 1, the threaded column 5 is provided on the left side of the drive motor 4, the movable seat 6 is provided on the left side of the drive motor 4, the mounting seat 7 is provided on the left side of the base 1, the pressing and fixing seat 8 is provided on the left side of the mounting seat 7, and the positioning slide rod 9 is clamped on the upper end face of the pressing and fixing seat 8. This design solves the problem of poor fixing effect of the original clamp on seamless tubes.

[0015] As the first embodiment of this utility model: a rotating shaft 21 is fitted on the right end face of the rotating seat 2, and the rotating shaft 21 is connected to the output end of an external servo motor. The support frame 3 is rotatably connected to the rotating seat 2 through a bearing connector. The support frame 3 can fix the position of the rotating seat 2. This design allows the user to select and adjust the rotation of the fixed seamless tube according to the usage requirements. The movable seat 6 is generally cone-shaped with a narrow left side and a wide right side. A threaded seat 61 is embedded on the right end face of the movable seat 6. The threaded seat 61 meshes with the threaded post 5. The inner side of the extrusion fixing seat 8 abuts against the outer side of the movable seat 6. The rotation of the threaded post 5 can drive the movable seat 6 to move axially through the threaded seat 61. The movable seat 6 can push the extrusion fixing seat 8 to unfold outward. A limit groove 62 is opened on the right end face of the movable seat 6. Limit plates 51 are provided above and below the drive motor 4. The limit plates 51 are connected to the drive motor 4. The limit groove 62 and the movable seat 6 slide and engage. The design of the limit groove 62 and the limit plate 51 makes the movement of the movable seat 6 more stable. The right end face of the mounting seat 7 is provided with a connecting frame 71. The mounting seat 7 is fixedly connected to the base 1 through the connecting frame 71. The left end face of the mounting seat 7 is provided with a baffle 72. Several sets of extrusion fixing seats 8 and mounting seats 7 are provided with equal specifications. The outer side of the extrusion fixing seat 8 is bonded with an anti-slip pad 81. The extrusion fixing seat 8 is slidably connected to the baffle 72 through the positioning slide rod 9. The positioning slide rod 9 makes the movement of the extrusion fixing seat 8 more stable. The anti-slip pad 81 can enhance the fixing effect of the extrusion fixing seat 8 on the seamless tube. The annular side of the positioning slide rod 9 is fitted with a return spring 91. The two ends of the return spring 91 abut against the upper end face of the extrusion fixing seat 8 and the lower end face of the baffle 72, respectively. The return spring 91 can help the extrusion fixing seat 8 return to its original position.

[0016] As a second embodiment of this utility model: The user places the end of the seamless tube on the outside of the extrusion fixing seat 8, and then operates the external controller to control the drive motor 4 to start. The output end of the drive motor 4 drives the threaded column 5 to rotate through the motor shaft. Since the threaded column 5 and the threaded seat 61 mesh with each other, the rotation of the threaded column 5 can drive the moving seat 6 to move along the axial direction. Since the outer surface of the moving seat 6 abuts against the inner side of the extrusion fixing seat 8, the movement of the moving seat 6 causes the extrusion fixing seat 8 to unfold outward along the surface of the positioning slide rod 9, and the outer surface of the extrusion fixing seat 8 abuts against the inner wall of the end of the seamless tube through the anti-slip pad 81, thereby fixing the end of the seamless tube. During grinding, two sets of this equipment can be set up to fix both ends of the seamless tube. At the same time, due to the setting of the support frame 3 and the rotating seat 2, in conjunction with the external servo motor, the fixed seamless tube can be rotated and adjusted to obtain a better grinding effect in conjunction with the grinding tools.
