[0015] Reference Figure 1 The embodiments of the utility model are further described in the drawings.

[0016] A novel tubular workpiece cutting device comprises a processing platform 1, a mounting mechanism 2, a positioning mechanism 4 and a cutting mechanism 3 arranged in sequence on the processing platform 1, wherein the positioning mechanism 4 comprises four positioning parts, the four positioning parts are distributed in a ring shape, and a clamping area 44 for fixing the workpiece is formed in the middle, and the four positioning parts are respectively an upper positioning part 40, a lower positioning part 41, a left positioning part 42 and a right positioning part 43, wherein the lower positioning part 41 is arranged on the processing platform 1, and its height position is adjustable, the upper positioning part 40 is located above the lower positioning part 41, and its height position is adjustable, and the left positioning part 43 is provided on the processing platform 1. The positioning portion 42 includes an abutting portion 420 and a sliding portion 421, the upper end surface of the sliding portion 421 is provided with a rack 422, the right positioning portion 43 includes an abutting portion 430 and a sliding portion 431, the lower end surface of the sliding portion 431 is provided with a rack 432, and a gear 6 is meshed between the rack 422 and the rack 432. When the gear 6 moves clockwise, the distance between the left positioning portion 42 and the right positioning portion 43 is in an expanded state, and when the gear 6 moves counterclockwise, the distance between the left positioning portion 42 and the right positioning portion 43 is in a reduced state.

[0017] The upper end positioning part 40 includes abutment block 3 405, an adjustment plate 400 and a support frame 401. The tail end of the abutment block 3 405 is fixed on the adjustment plate 400. The support frame 401 is provided with an adjustment slot 402. One end of the adjustment plate 400 is inserted into the adjustment slot 402. A compression spring 403 is provided between the top wall of the adjustment slot 402 and the adjustment plate 400. The compression spring 403 drives the adjustment plate 400 to move toward the bottom wall of the adjustment slot 402. A bolt 1 404 is penetrated in the support frame 401. The bolt 1 404 is penetrated into the bottom wall of the adjustment slot 402 and abuts against the bottom wall of the adjustment plate 400. The lower end positioning part 41 includes abutment block 410 and a support block 411. The bottom of the support block 411 is matched with a bolt 2 412. The tail end of the bolt 2 412 passes through the processing platform 1 and is matched with a nut. The abutting portion 1 420 , the abutting portion 2 430 , the abutting block 3 405 and the abutting block 410 all have an inwardly concave arc surface 413 , and the arc surface 413 abuts against the outer wall of the workpiece.

[0018] Working principle: After the head end of the workpiece to be cut passes through the clamping area 44, it is located below the cutting mechanism 3, and its tail end is fixed by the mounting mechanism 2. The lower end positioning part 41 can be adjusted in height by operating the second bolt 412 according to the known workpieces, thereby adjusting the distance between the upper end positioning part 40 and the lower end positioning part 41, so that it can be more suitable for workpieces of different sizes. When the workpiece is passed into the clamping area 44, if the distance between the upper end positioning part 40 and the lower end positioning part 41 is too small, the adjustment plate 400 on the upper end positioning part 40 will be forced to squeeze the compression spring 403, and be lifted up for fine adjustment, so as to facilitate the insertion of the workpiece. After the workpiece is assembled, the compression spring 403 applies force to make the abutment block 3 405 press against the outer surface of the workpiece. At the same time, when the size of the workpiece and the clamping area 44 do not match, the adjustment plate 400 can be moved upward by operating the bolt 1 404, so as to adjust the distance between the abutment block 3 405 and the abutment block 4 410. When cutting workpieces of the same size, the upper positioning part 40 and the lower positioning part 41 only need to be adjusted for the first time, and the small gap can be adjusted autonomously by the cooperation of the adjustment plate 400 and the compression spring 403. After the workpiece passes through the clamping area 44, the motor drives the gear 6 to rotate counterclockwise to reduce the distance between the left positioning part 42 and the right positioning part 43 until the abutment part 1 420 and the abutment part 2 430 contact the outer wall of the workpiece. At this time, the workpiece is clamped and fixed by the positioning parts of different stations on all sides, and the cutting mechanism 3 can start the cutting process.

[0019] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
