Description

Technical Field

[0001] This utility model relates to the field of steel pipe surface polishing, specifically to a seamless steel pipe outer surface polishing equipment. Background Technology

[0002] After stainless steel pipes are produced, the outer surface of the pipes needs to be ground and polished. A well polished pipe not only meets the requirements for surface smoothness, but also has a more beautiful appearance.

[0003] Polishing typically uses a polishing wheel as the polishing tool. Specifically, after the steel pipe is placed on the polishing machine, the polishing wheel located around the circumference of the steel pipe rotates, thereby rubbing the surface of the steel pipe, thus polishing the outer surface of the steel pipe.

[0004] However, this polishing method is less efficient. Since the steel pipe is long and narrow, this polishing method usually requires moving the steel pipe during processing to ensure that the entire outer surface of the steel pipe can be polished.

[0005] Currently, multiple polishing units are used to work together to improve the efficiency of polishing the outer surface of seamless steel pipes, but it is still generally necessary to move the steel pipe during processing. Moreover, since the polishing operation applies a certain force to the seamless steel pipe, it is also necessary to clamp the seamless steel pipe to keep it fixed, which makes it difficult to polish the clamped parts of the seamless steel pipe. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a seamless steel pipe outer surface polishing device to solve the technical problems of low efficiency of seamless steel pipe outer surface polishing and difficulty in polishing the clamped part of the seamless steel pipe in the prior art.

[0007] To achieve the above objectives, this utility model provides a polishing device for the outer surface of seamless steel pipes, including a polishing motor for driving the entire device to polish the outer surface of the seamless steel pipes, and the polishing device further includes:

[0008] A polishing cylinder is fixedly connected to the output shaft of a polishing motor. The polishing cylinder is rotatably connected to a connecting seat, and several abrasive strips are detachably connected to the inner wall of the polishing cylinder for polishing the outer surface of the seamless steel pipe inside the polishing cylinder.

[0009] A support tube is fixedly connected to the connecting seat. The support tube is located at the center inside the polishing cylinder, and several positioning sliders are slidably connected on the support tube to support and fix the inner wall of the seamless steel pipe.

[0010] Furthermore, the polishing motor and the connecting seat are both fixedly connected to the base, and a support seat is also fixedly connected to the base. The polishing cylinder passes through the support seat and is rotatably connected to it.

[0011] Furthermore, the inner wall of the outer port of the support tube is provided with an internal thread, and a screw is connected to the outer port of the support tube by the internal thread. The inner end of the screw is fixedly connected to a push rod, and the push rod is slidably connected inside the support tube.

[0012] Furthermore, the outer side of the push rod is provided with several arc-shaped grooves, and the part of the positioning slider located inside the support tube is located in the corresponding arc-shaped groove.

[0013] Furthermore, a connecting cap is fixedly connected to the outer end of the screw, and the connecting cap is provided with a rotating hole.

[0014] Furthermore, the polishing equipment is also equipped with a rotating rod, the outer diameter of which is the same as the inner diameter of the rotating hole.

[0015] The advantages of this utility model are: 1. By setting a polishing cylinder to polish the outer surface of the seamless steel pipe as a whole, all parts of the outer surface of the seamless steel pipe can be polished at the same time, which greatly improves efficiency and saves time.

[0016] 2. The polishing cylinder can polish the entire outer surface of the seamless steel pipe without any dead corners, ensuring complete polishing.

[0017] 3. By fixing the seamless steel pipe from the inside through the support tube, the polishing cylinder can polish the outer surface of the seamless steel pipe without the clamping mechanism preventing the clamped part from being unable to be polished.

[0018] 4. By rotating the screw, the push rod inside the screw moves, which in turn lifts the positioning slider, so that the outer end of the positioning slider supports the seamless steel pipe to achieve positioning of the seamless steel pipe. The operation is simple and convenient. Attached Figure Description

[0025] Detailed implementation methods and principles

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] The first aspect of this utility model is as follows: Figure 1 and Figure 2 As shown, in order to improve the polishing efficiency of the outer surface of the seamless steel pipe and to avoid the parts of the seamless steel pipe that are clamped from not being polished, this utility model is provided with a polishing cylinder 105 to perform uniform polishing treatment on the entire outer surface of the seamless steel pipe. That is to say, when the polishing cylinder 105 rotates, the abrasive strips 114 inside it can polish the outer surface of the seamless steel pipe as a whole, and can polish all parts of the outer surface of the seamless steel pipe at the same time, which greatly improves the efficiency.

[0029] Specifically, a polishing motor 102, a connecting seat 103, and a support seat 104 are fixedly connected to the base 101. The polishing cylinder 105 is fixedly connected to the output shaft of the polishing motor 102, and is also rotatably connected to the connecting seat 103. Simultaneously, the polishing cylinder 105 passes through and is rotatably connected to the support seat 104. The polishing motor 102 provides the driving function, while the connecting seat 103 and the support seat 104 provide support and stability.

[0030] In addition, such as Figure 3 As shown, several abrasive strips 114 are detachably connected to the inner wall of the polishing cylinder 105 for polishing the outer surface of the seamless steel pipe inside the polishing cylinder 105. After a period of use, the abrasive strips 114 can be removed and replaced with new abrasive strips 114 to ensure the polishing effect for different seamless steel pipes each time.

[0031] The polishing motor 102 drives the polishing cylinder 105 to rotate. The rotation of the polishing cylinder 105 can polish the entire outer surface of the seamless steel pipe fixed inside, without dead corners, ensuring that the entire outer surface of the seamless steel pipe is polished.

[0032] The seamless steel pipe is fixed inside the polishing cylinder 105 by a support pipe 106, such as... Figure 3 and Figure 4 As shown:

[0033] The inner end of the support tube 106 is fixedly connected to the connecting seat 103, and the support tube 106 is located at the center inside the polishing cylinder 105. Several positioning sliders 112 are slidably connected on the support tube 106. After the positioning sliders 112 extend outward, the outer ends of the positioning sliders 112 can support the inner wall of the seamless steel tube and fix it.

[0034] To specifically implement this process, in such a way... Figure 4 As shown, an internal thread is provided on the inner wall of the outer port of the support tube 106, and a screw 107 is connected to the internal thread of the outer port of the support tube 106. A push rod 110 is fixedly connected to the inner end of the screw 107, and the push rod 110 is slidably connected inside the support tube 106. Several arc-shaped grooves 111 are also provided on the outer side of the push rod 110. The part of the positioning slider 112 located inside the support tube 106 is located in the corresponding arc-shaped groove 111, and each positioning slider 112 corresponds to one arc-shaped groove 111.

[0035] When the push rod 110 moves forward, the arc-shaped groove 111 on the outer side of the push rod 110 also moves forward, which causes the rear arc surface of the arc-shaped groove 111 to abut against the positioning slider 112. As the arc-shaped groove 111 moves forward, the rear arc surface of the arc-shaped groove 111 gradually pushes the positioning slider 112 outward, so that the part of the positioning slider 112 located outside the support tube 106 will protrude more and more, eventually pressing tightly against the seamless steel pipe between the support tube 106 and the polishing cylinder 105, thereby achieving the positioning of the seamless steel pipe.

[0036] The forward and backward movement of the drive rod 110 is achieved through the following mechanism: a connecting cap 108 is fixedly connected to the outer end of the screw 107, and the connecting cap 108 is provided with a rotating hole 109. In addition, the polishing equipment is also equipped with a rotating rod 113, the outer diameter of which is the same as the inner diameter of the rotating hole 109.

[0037] If the push rod 110 needs to be moved back and forth, the rotating rod 113 is inserted into the rotating hole 109 in advance. Then, the screw 107 is rotated by holding the rotating rod 113. By changing the direction of rotation, the screw 107 can move back and forth, thereby driving the push rod 110 to move back and forth. Driving the push rod 110 to move forward can drive the positioning slider 112 to be lifted up, so that the outer end of the positioning slider 112 supports the seamless steel pipe to achieve positioning of the seamless steel pipe. Driving the push rod 110 to move backward will cause the positioning slider 112 to fall back into the corresponding arc groove 111. The whole operation is not only simple and convenient, but also saves time and effort.

[0038] When not in use, the rotating rod 113 can be removed from the rotating hole 109, so that the rotating rod 113 will not block the entry and exit of the seamless steel pipe, making it convenient to send the seamless steel pipe into the polishing cylinder 105 or take it out from the polishing cylinder 105. Detailed Implementation

[0039] Before polishing the entire outer surface of the seamless steel pipe, the rotating rod 113 is first removed from the rotating hole 109, and then the seamless steel pipe is inserted into the polishing cylinder 105, while the support tube 106 is also inserted into the seamless steel pipe.

[0040] Then, insert the rotating rod 113 into the rotating hole 109, hold the rotating rod 113 and rotate the screw 107 so that the screw 107 can move forward, thereby driving the push rod 110 to move forward. Driving the push rod 110 to move forward can drive the positioning slider 112 to lift up, so that the outer end of the positioning slider 112 supports the seamless steel pipe to achieve positioning of the seamless steel pipe.

[0041] After the above preparations are completed, the polishing motor 102 is started. The polishing motor 102 drives the polishing cylinder 105 to rotate. Several abrasive strips 114 that are detachably connected to the inner wall of the polishing cylinder 105 are used to polish the outer surface of the seamless steel pipe as a whole. This can polish all parts of the outer surface of the seamless steel pipe at the same time, without dead corners, greatly improving efficiency and ensuring complete polishing.

[0042] After the polishing operation is completed, turn off the polishing motor 102, and then hold the rotating rod 113 to rotate the screw 107 in the opposite direction so that the screw 107 can move backward, thereby driving the push rod 110 to move backward. Driving the push rod 110 to move backward will cause the positioning slider 112 to fall back into the corresponding arc groove 111, so that the seamless steel pipe is loosened and can be easily removed.

[0043] Finally, remove the rotating rod 113 from the rotating hole 109, and then remove the seamless steel pipe from the polishing cylinder 105.

[0044] Based on the above, this utility model uses a polishing cylinder 105 to polish the entire outer surface of the seamless steel pipe, simultaneously polishing all parts of the outer surface, greatly improving efficiency and saving time. The polishing cylinder 105 can polish the entire outer surface of the seamless steel pipe without any dead angles, ensuring complete polishing. By fixing the seamless steel pipe from the inside using the support tube 106, the polishing cylinder 105 can polish the outer surface of the seamless steel pipe without the clamping mechanism preventing the clamped parts from being left unpolished. Rotating the screw 107 moves the push rod 110 inside the screw 107, thereby lifting the positioning slider 112, allowing the outer end of the positioning slider 112 to support the seamless steel pipe and achieve positioning. The operation is simple and convenient.
