Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-4, the clamping structure for spiral pipe end groove forming equipment disclosed by the utility model comprises a workbench 1 and a frame body 2, wherein the workbench 1 is fixedly welded on the surface of the workbench 1, a fixed frame 3 is fixedly installed on the inner wall of the workbench 1, a clamping plate 4 is installed inside the fixed frame 3 in a penetrating manner, a sliding groove 5 is reserved inside the clamping plate 4, a rotating shaft 6 is arranged inside the sliding groove 5, the end parts of the rotating shaft 6 penetrate through the frame body 2, worm wheels 7 are fixed on the end parts of the two rotating shafts 6, a worm 8 is connected to the side surface of each worm wheel 7, the worm 8 is rotatably connected with the workbench 1, a motor 9 is fixed on the end part of one worm 8, a support 10 is fixed on the side wall of the motor 9, the end part of the support 10 is fixedly connected with the frame body 2, and transmission mechanisms 11 are installed on the surfaces of the rotating shaft 6 and the worm 8.

Splint 4 and pivot 6 are threaded connection, and splint 4 and mount 3 constitute block type sliding construction, and threaded connection can drive splint 4 displacement when making pivot 6 rotatory to realize the centre gripping fixed to the body, and the centre of a circle that the centre gripping is fixed is inconvenient, and then convenient follow-up processing.

The screw thread direction of pivot 6 is the same on the horizontal direction, and the screw thread direction of pivot 6 is opposite on vertical direction, and above-mentioned screw thread direction makes pivot 6 when the pivoted, can drive splint 4 and do the motion of drawing close between two parties, perhaps keeps away from the motion to ensure that the centre gripping operation can realize smoothly.

Worm wheel 7 is connected for the meshing with worm 8, and worm wheel 7 and worm 8 all are provided with two, and two worm 8's spiral opposite direction, meshing connection can drive worm wheel 7 rotatory when making worm 8 rotate to for 6 rotations of follow-up pivot provide power source, and the transmission of worm wheel 7 has the auto-lock characteristics, can strengthen the centre gripping effect.

The transmission mechanism 11 comprises a transmission wheel 1101 and a belt 1102, the transmission wheel 1101 is fixed on the surfaces of the rotating shaft 6 and the worm 8 in the vertical direction, the belt 1102 is installed between the transmission wheels 1101, and the transmission mechanism can drive the rotating shaft 6 and the worm 8 to operate simultaneously when operating, so that power output is provided for the movement of the clamping plate 4, and the time required by clamping is shortened.

The working principle and the beneficial effects of the utility model are as follows: when the clamping structure for the spiral pipe end groove forming equipment is used, a pipe body is firstly placed between four clamping plates 4, then a motor 9 is started to drive one worm 8 to rotate, the worm 8, the other worm 8 and a rotating shaft 6 in the vertical direction are mutually connected through a conveying wheel 1101 and a belt 1102, so when the worm 8 connected with the motor 9 rotates, the other worm 8 and the rotating shaft 6 in the vertical direction are driven to synchronously rotate, then the worm 8 drives the rotating shaft 6 in the horizontal direction to rotate by utilizing the meshing relation between the worm 8 and a worm wheel 7, the thread directions of the rotating shaft 6 in the horizontal reverse direction are the same, but the spiral directions of the worms 8 are opposite, so when the rotating shaft 6 in the horizontal direction rotates, the threads on the surface push the clamping plates 4 to be close to each other, and meanwhile, the thread directions of the rotating shaft 6 in the vertical direction are opposite, so when the pivot 6 of vertical direction is synchronous rotation along with worm 8, can utilize self and splint 4's screw thread relation drive splint 4 to be the motion of drawing close each other, to sum up, when motor 9 moves, can drive splint 4 and do the motion of drawing close between two parties, until realizing with the body that the centre gripping is fixed can stop motor 9, afterwards, can carry out subsequent groove operation, and at last, after the groove operation is accomplished, the start motor 9 run backwards, can relieve the centre gripping to the body, send it equipment surface to drag down can.
