Abstract
A circular blank clamping mechanism comprises a fixed clamping device and a floating clamping device which are in the same structure, wherein the fixed clamping device comprises a 20-degree clamping oil cylinder, two ends of a first guide rod are respectively connected with the 20-degree clamping oil cylinder and a first clamp tile, a second guide rod is connected with a horizontal clamping oil cylinder and a second clamping tile, a vertical clamping oil cylinder is fixed in the middle of a tank body, and two ends of a third guide rod in the middle of the interior of the tank body are respectively connected with the vertical clamping oil tank and a V-shaped clamping tile. The clamping mechanism can achieve motions such as automatic clamping, loosening and cutter relieving on the condition that the center position of blank is not changed. Besides, the mechanism enables a sawed surface to be separated from a saw blade after sawing, the saw blade does not scratch the sawed surface during the lifting process and automatically resets before next sawing, automatic process requirements of a steel tube gang saw machine are met, and the circular blank clamping mechanism has the advantages of being simple and compact in structure, good in clamping effect, and capable of relieving a cutter and achieving automatic control.
Description
Technical field
The utility model relates to the device that is applied to steel tube gang saw machine and the compound clamping of other sawing needs, particularly a kind of round blank clamping mechanism.
Background technology
External similar clamping device clamping cylinder adopts non-standard oil cylinder, and vertical clamping employing swing type, and the process and assemble difficulty is large, the assembling difficulty.Domestic similar clamping device structure is more scattered, and clamping is unstable and do not possess cutter relieving function, so that saw blade easily scratches the sawing section when lifting.Have the clamping stability reliability low, process and assemble is complicated, the shortcoming that maintenance cost is high.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of round blank clamping mechanism, the round blank that reliably clamping is single, the diameter of clamping is 180mm-426mm, in the situation that do not change the blank center, realize Automatic-clamping, unclamp and clamp the actions such as cutter relieving; In addition, the utility model makes the sawing section separate with saw blade after sawing is finished, saw blade can not scratch section in lifting process, and before next time sawing, automatically reset, satisfied the full-automatic technological requirement of steel tube gang saw machine, but had simple and compact for structure, good clamping effect cutter relieving and can realize the advantages such as automation control.
In order to achieve the above object, the technical scheme taked of the utility model is:
A kind of round blank clamping mechanism, comprise fixed clamping device 14 and floating clamping device 13 with same structure, a side that is connected with main frame 15 is fixed clamping device 14, the outside be called floating clamping device 13, fixed clamping device 14 and floating clamping device 13 link together by tool retracting device 8, described fixed clamping device 14 comprises 20 ° of clamping cylinders 2, at 20 ° of clamping cylinders, 2 afterbody installation position displacement sensors 1,20 ° of clamping cylinders 2 are fixed on casing 12 1 sides, the first guide rod 3 two ends of these casing 12 1 side inside respectively with 20 ° of clamping cylinders 2 be connected that folder watts 4 is connected and along 20 ° of directions slips, horizontal-clamping oil cylinder 7 is horizontally fixed on casing 12 opposite sides, the second guide rod 6 two ends of these casing 12 opposite side inside respectively with horizontal-clamping oil cylinder 7 be connected that folder watts 5 is connected and the along continuous straight runs slip, vertical clamping oil cylinder 11 is fixed on the casing centre, and the 3rd guide rod 10 two ends of casing 12 inside middle are connected watts 9 with vertical clamping oil cylinder 11 respectively and are connected and vertically slide in casing 12 inside with V-arrangement.
Because the vertical clamping oil cylinder adopts large cylinder diameter to continue to the mode of pressing, make clamping more reliable and more stable, 20 ° clamp the oil cylinder that adopts with displacement transducer, and adopt hydraulic locking to make the positioning accuracy of oil cylinder more accurate, guarantee the clamping center, thus guarantee that clamping is reliably firm, and all oil cylinders of the utility model all adopt the standard oil cylinder, make process and assemble easier, maintenance cost is low.The utlity model has the clamping cutter relieving function, effectively protect the sawing cross section quality.Also has compact overall structure, the advantage of being convenient to install.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, a kind of round blank clamping mechanism, comprise fixed clamping device 14 and floating clamping device 13 with same structure, a side that is connected with main frame 15 is fixed clamping device 14, the outside be called floating clamping device 13, fixed clamping device 14 and floating clamping device 13 link together by tool retracting device 8, described fixed clamping device 14 comprises 20 ° of clamping cylinders 2, at 20 ° of clamping cylinders, 2 afterbody installation position displacement sensors 1, be used for detecting the displacement of this oil cylinder, 20 ° of clamping cylinders 2 are fixed on casing 12 1 sides, the first guide rod 3 two ends of these casing 12 1 side inside respectively with 20 ° of clamping cylinders 2 be connected that folder watts 4 is connected and along 20 ° of directions slips, horizontal-clamping oil cylinder 7 is horizontally fixed on casing 12 opposite sides, the second guide rod 6 two ends of these casing 12 opposite side inside respectively with horizontal-clamping oil cylinder 7 be connected that folder watts 5 is connected and the along continuous straight runs slip, vertical clamping oil cylinder 11 is fixed on casing 12 centres, and the 3rd guide rod 10 two ends of casing 12 inside middle are connected watts 9 with vertical clamping oil cylinder 11 respectively and are connected and vertically slide at box house with V-arrangement.
Tool retracting device 8 is a nonstandard oil cylinder, and its cylinder body is fixed on the fixed clamping device 14, thereby fixed clamping device 14 and floating clamping device 13 are linked together.
Operation principle of the present utility model is:
Fixed clamping device 14 is installed on the main frame 15 in the integral hoisting of A face.At first tool retracting device 8 is in the state of stretching out, vertical clamping oil cylinder 11 promotes V-arrangements folder watts 9 by the 3rd guide rod 10 blank is held up a little more than roller table surface, 20 ° of clamping cylinders 2 that then displacement transducer 1 be housed promote the first folder watts 4 by the first guide rod 3, make it to contact with blank, make 2 lockings of 20 ° of clamping cylinders by hydraulic circuit, final level clamping cylinder 7 promotes the second folder watts 5 with blank clamping by the second guide rod 6, and floating clamping device 13 also carries out identical action simultaneously.This moment, the saw blade worker proceeded to blank cylindrical certain distance, and the saw blade cutter relieving is retracted, and then tool retracting device 8 is retracted, and floating clamping device 13 and fixed clamping device 14 closely are close together.It is firm that integral body of whole clamping device formation this moment will be justified the blank clamping, and the saw blade worker advances to cut off pipe.After sawing finished, tool retracting device 8 stretched out, and hauled out certain distance by the round blank that floating clamping device 13 will cut off, and section and saw blade are separated, and then saw blade also stretches out a segment distance by other mechanism, and saw blade and rear section are separated, and then saw blade lifts.Horizontal-clamping oil cylinder 7 is retracted, and 20 ° of clamping cylinders 2 are retracted, and vertical clamping oil cylinder 11 is retracted.The discharging of blank leading portion, back segment continues material loading.Prepare next time sawing.Whole sawing process adopts Automatic Control, repeats sawing.
