DETAILED DESCRIPTION

[0024] The utility model discloses a further configuration in a preferable example can be: drive mechanism includes pivot, rotary lever, connecting rod and locking piece, pivot vertical rotation connects in the middle position of base, the rotary lever horizontal arrangement, and middle position fixed in the upper end of pivot, one end of connecting rod rotation connects in the end of rotary lever, and the other end rotation connects in the lower end of clamping rod, locking piece is used for fixing pivot.

[0025] As shown in Figure 1 , Figure 2 , a steel pipe clamp for steel pipe thread processing equipment comprises a base 1, a sliding rail 2, a clamp rod 3, a driving mechanism 4, a push rod 5 and a push block 6.

[0026] As shown in Figure 1 , Figure 2 , the base 1 is horizontally arranged on a processing lathe, and a bracket 7 is vertically arranged at each end of the base 1, and an arc-shaped clamping groove 71 is arranged on the bracket 7 to support the steel pipe. The surface of the clamping groove 71 is rotationally connected with a ball 72 to facilitate the sliding of the steel pipe.

[0027] As shown in Figure 1 , Figure 2 , the sliding rail 2 is horizontally arranged on both sides of the base 1, and the clamp rod 3 is vertically arranged on the sliding rail 2 and transversely slidably connected to the sliding rail 2 to clamp and fix the steel pipe. A rubber pad 31 is arranged on the inner wall of the clamp rod 3 to prevent the clamp rod 3 from damaging the steel pipe.

[0028] As shown in Figure 1 , Figure 2 , the driving mechanism 4 is used to control the relative sliding of a pair of clamp rods 3, and the driving mechanism 4 comprises a rotating shaft 41, a rotating rod 42, a connecting rod 43 and a locking piece 44. The rotating shaft 41 is vertically rotationally connected to the middle position of the base 1, the rotating rod 42 is horizontally arranged and fixed to the upper end of the rotating shaft 41 at the middle position, one end of the connecting rod 43 is rotationally connected to the end of the rotating rod 42, and the other end is rotationally connected to the lower end of the clamp rod 3.

[0029] As shown in Figure 1 , Figure 2 , the locking piece 44 is used to fix the rotating shaft 41, and the locking piece 44 comprises a gear 45, a rack 46 and a screw rod 47. The gear 45 is rotationally connected to the lower end of the rotating shaft 41, the rack 46 is horizontally slidably connected to the base 1 and engaged with the gear 45, and the screw rod 47 is horizontally threadedly connected to the base 1 and rotationally connected to the rack 46.

[0030] As shown in Figure 1 , Figure 2 , the push rod 5 is rotationally arranged at the middle position of the clamp rod 3 and horizontally extends towards the processing direction of the steel pipe, and a torsional spring 51 is arranged at the rotating position of the push rod 5. An inclined block 32 is arranged on the clamp rod 3 to abut against the inner side wall of the push rod 5, so that there is always a certain angle between the push rod 5 and the clamp rod 3 to facilitate the rotation of the push rod 5. The push block 6 is rotationally connected to the front end position of the push rod 5 and used to clamp the side wall of the steel pipe.

[0031] When the steel pipe needs to be clamped for machining, the steel pipe is placed in the clamping groove 71 on the bracket 7, and the steel pipe is probed forward, then the screw rod 47 is controlled to rotate, at this time the screw rod 47 drives the rack 46 to slide horizontally, the rack 46 drives the gear 45 and the rotating shaft 41 to rotate together.

[0032] Then the rotating shaft 41 drives the rotating rod 42 to rotate, and under the cooperation of the connecting rod 43, the clamping rod 3 is controlled to gradually approach each other. In this process, when the clamping rod 3 approaches each other, the push rod 5 and the push block 6 are synchronously moved, so that the push block 6 first abuts against the outer wall of the steel pipe and clamps the steel pipe.

[0033] With the approaching of the clamping rod 3, the pair of push rods 5 are folded together, and under the clamping action of the push block 6, the steel pipe is automatically pushed to slide forward. When the steel pipe abuts against the machining tool, the clamping rod 3 drives the push rod 5 to continue to move, at this time the steel pipe and the push block 6 slide relatively. Until the clamping rod 3 clamps the outer wall of the steel pipe, the clamping and fixing of the steel pipe are realized, so as to facilitate the machining of the steel pipe.

[0034] When the steel pipe is machined, the screw rod 47 is controlled to rotate reversely, at this time the screw rod 47 drives the rack 46 to slide reversely horizontally, the rack 46 drives the gear 45 and the rotating shaft 41 to rotate reversely together. Then the rotating shaft 41 drives the rotating rod 42 to rotate, and under the cooperation of the connecting rod 43, the clamping rod 3 is controlled to gradually move away from each other. When the clamping rod 3 gradually moves away from each other, the push rod 5 gradually separates, so that the push block 6 drives the steel pipe to move reversely, so as to realize the automatic separation of the steel pipe and the tool, and facilitate the thread machining of the next steel pipe.
