Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, in particular to a positioning fixture for cutting seamless steel pipes. Background Art

[0002] Seamless steel pipes have hollow cross-sections and are widely used as pipes for transporting fluids, such as oil, natural gas, coal gas, water and certain solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when their bending and torsional strengths are the same. They are economical cross-section steel materials. During processing, they need to be cut. In order to improve the cutting accuracy, positioning fixtures are generally used to assist in positioning and clamping during cutting. After searching, a Chinese patent with publication number CN220145871U discloses a fixture for seamless steel pipe processing. When in use, when clamping and fixing the seamless steel pipe, the push rod is extended and retracted, and the sliding platform is pushed back and forth to move the seamless steel pipe back and forth to avoid repeated clamping. However, it only clamps the seamless steel pipe at one position. Since the seamless steel pipe is relatively long, the support stability of only one point is poor, and the seamless steel pipe will deviate during processing, especially during cutting of the seamless steel pipe. Therefore, a positioning fixture for cutting seamless steel pipes is designed, which has two support points and can be used for cutting and feeding to improve the cutting stability of the seamless steel pipes.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-3A positioning fixture for cutting seamless steel pipes comprises a horizontal slide rail 1 and a seamless steel pipe, and also comprises two seamless steel pipe clamping frames 2 arranged in parallel front and back, both seamless steel pipe clamping frames 2 are provided with seamless steel pipe clamps, the seamless steel pipe clamp located on the rear side can fix and clamp the seamless steel pipe, and the seamless steel pipe clamp located on the front side can cooperate with the seamless steel pipe guide sliding, the two seamless steel pipe clamping frames 2 can cooperate with the horizontal slide rail 1 to slide back and forth, the seamless steel pipe clamping frame 2 located on the front side can be locked on the front side of the horizontal slide rail 1, and also comprises a feeding positioning driving mechanism for driving the seamless steel pipe clamping frame 2 located on the rear side to move back and forth.

[0023] Specifically, the seamless steel pipe clamping fixture includes a supporting ring plate 3 fixedly installed on the top of the seamless steel pipe clamping frame 2, two side ring plates 4 with adjustable spacing are symmetrically arranged on both sides above the supporting ring plate 3, and also includes a clamping drive component for adjusting the spacing between the two side ring plates 4. The inner sides of the supporting ring plate 3 and the side ring plate 4 located on the front side are both installed with multiple universal balls 8. The supporting ring plate 3 is convenient for supporting the seamless steel pipe from the bottom, and the two side ring plates 4 on both sides are convenient for clamping the seamless steel pipe supported on the supporting ring plate 3. Through the clamping drive component, the side ring plate 4 is convenient for pushing to the middle, so that the seamless steel pipe can be clamped and released.

[0024] Specifically, the clamping drive assembly is set into two groups and is arranged on the left and right sides of the seamless steel pipe clamp 2. The clamping drive assembly includes a clamping drive cylinder 5 fixedly installed on one side of the seamless steel pipe clamp 2. The output shaft of the clamping drive cylinder 5 is fixedly connected to the side ring plate 4 on the same side through a fixed plate 6. The output shaft of the clamping drive cylinder 5 is extended or shortened through the clamping drive cylinder 5, and the side ring plate 4 is driven to move left and right through the fixed plate 6. Furthermore, a guide slide column 7 that horizontally slides with the seamless steel pipe clamp 2 is fixedly installed on the fixed plate 6. The guide slide column 7 facilitates horizontal guidance of the fixed plate 6, thereby increasing the stability of the side ring plate 4 during horizontal movement.

[0025] Specifically, the feeding positioning drive mechanism includes a horizontal screw 10, and a feeding chute 9 matched with the horizontal screw 10 is opened on the horizontal slide rail 1. The horizontal screw 10 is rotatably connected in the feeding chute 9. The horizontal screw 10 is threadedly connected with a feeding slider 11 that slides with the feeding chute 9. The seamless steel pipe clamp 2 located on the rear side is fixedly connected to the feeding slider 11, and also includes a driving member for driving the horizontal screw 10 to rotate. Through the driving member, it is easy to drive the horizontal screw 10 to rotate clockwise or counterclockwise, thereby driving the feeding slider 11 to slide forward or backward in the feeding chute 9, thereby driving the seamless steel pipe clamp 2 on the rear side to move forward or backward synchronously.

[0026] Specifically, the driving component includes a feeding motor 13. A motor slot 12 is opened on the horizontal slide rail 1 below the feeding chute 9. The feeding motor 13 is fixedly installed in the motor slot 12. The output shaft of the feeding motor 13 is connected to one end of the horizontal screw 10 through a synchronous belt 14. When the feeding motor 13 is started, the output shaft of the feeding motor 13 rotates clockwise or counterclockwise. Through the transmission cooperation of the synchronous belt 14, the horizontal screw 10 is driven to rotate clockwise or counterclockwise.

[0027] Specifically, a guide slide 15 is fixedly installed at the bottom of the seamless steel pipe clamp 2 on the front side, and a supporting slide 16 that slides with the guide slide 15 is opened on the horizontal slide rail 1. The supporting slide 16 is arranged parallel to the feeding slide 9. Through the cooperation of the supporting slide 16 and the guide slide 15, it is convenient to ensure that the seamless steel pipe clamp 2 on the front side slides back and forth.

[0028] Specifically, it also includes a positioning column 18. A positioning hole 17 that slidably cooperates with the positioning column 18 is opened on the front end of the horizontal slide rail 1 and the guide slide 15. Through the cooperation between the positioning column 18 and the positioning hole 17, when the seamless steel pipe clamp 2 located on the front side moves to the front end and the positioning holes 17 on the guide slide 15 and the horizontal slide rail 1 are aligned, the positioning column 18 is inserted thereinto so that the seamless steel pipe clamp 2 on the front side can be locked with the horizontal slide rail 1, thereby preventing the seamless steel pipe clamp 2 on the front side from continuing to slide back and forth, thereby ensuring that the position of its support point remains unchanged.

[0029] When in use, the seamless steel pipe is first placed on the seamless steel pipe clamp on the front side, and then the synchronous belt 14 drives the seamless steel pipe and the seamless steel pipe clamp frame 2 on the front side and the seamless steel pipe home to move backwards, and the rear end of the seamless steel pipe is inserted into the seamless steel pipe clamp on the rear side, and the seamless steel pipe is clamped and fixed by the seamless steel pipe clamp on the rear side, and then the seamless steel pipe clamp frame 2 on the front side drives the seamless steel pipe clamp on the front side to move to the front end of the horizontal slide rail 1 and locks the position of the seamless steel pipe clamp frame 2 on the front side with the horizontal slide rail 1, and then starts the feeding positioning drive mechanism to drive the seamless steel pipe clamp frame 2 on the rear side to move forward until the front end of the seamless steel pipe extends out of the seamless steel pipe on the front side by a certain cutting safety distance, and then after cutting the seamless steel pipe, continue to push the seamless steel pipe through the feeding positioning drive mechanism to cut the next section, and after cutting is completed, release the clamping of the remaining seamless steel pipe by the seamless steel pipe clamp on the rear side.
