The tightening device of the utility model has simple structure and convenient operation; the quick clamping and synchronous rotation of the cylindrical part to be assembled can be realized, the use requirement of the screw thread assembly of the cylindrical part is met, and the screw thread assembly machine is suitable for batch processing.
Description
Technical Field
The utility model relates to a screw up device for cylinder belongs to the part assembly field.
Background
Some cylindrical part products are butt-jointed and assembled in a threaded connection mode, the traditional technology carries out threaded butt-joint operation on the cylindrical part products, and one operation method is manual threaded tightening, and the operation is only suitable for cylindrical butt-jointed parts with small threaded screwing force. For a cylindrical butt joint part with large screw thread screwing force, only a cylindrical part clamp can be used for operation. Traditional cylinder anchor clamps are through radially pressing from both sides tight back of cylinder and close soon again and screw up, and cylinder anchor clamps structure is comparatively complicated, and need constantly adjust the clamping position of each radial clamp splice during the operation, complex operation, and assembly efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a screw up device for cylinder to solve complicated, the assembly efficiency low scheduling problem of traditional cylinder anchor clamps structure.
The utility model aims at realizing through the following technical scheme:
the utility model discloses a tightening device for a cylindrical part, which comprises a semicircular clamping sleeve and a force rod connected with a free end of the semicircular clamping sleeve through a pin shaft, wherein the front end of the force rod is a clamping plane; when the force rod is turned to one side of the opening end of the semicircular jacket, the clamping plane at the front end of the force rod and the inner wall of the semicircular jacket clamp the cylindrical part to be assembled; when the force rod is turned to the closed side of the semicircular jacket, the clamping plane at the front end of the force rod and the inner wall of the semicircular jacket release the cylindrical part to be assembled.
When the cylindrical part is screwed and assembled, a semicircular jacket of the screwing device is sleeved on the outer wall of the cylindrical part to be assembled, and the force rod is turned towards one side of the opening end of the semicircular jacket, so that a clamping plane at the front end of the force rod clamps the cylindrical part to be assembled inwards; and continuously overturning the force rod, wherein the tightening device can drive the cylindrical part to be assembled to synchronously rotate. When the cylindrical part is loosened, the force rod only needs to be turned to the closed side of the semicircular jacket, and the cylindrical part to be assembled is loosened by the clamping plane at the front end of the force rod and the inner wall of the semicircular jacket, so that the screwing device can be separated from the cylindrical part to be assembled.
The inner side surface of the semicircular jacket and the clamping plane at the front end of the force rod are provided with elastic gaskets, so that the side wall of the cylindrical part to be assembled is prevented from being damaged by the tightening device.
Advantageous effects
The tightening device of the utility model has simple structure and convenient operation; the quick clamping and synchronous rotation of the cylindrical part to be assembled can be realized, the use requirement of the screw thread assembly of the cylindrical part is met, and the screw thread assembly machine is suitable for batch processing.
Drawings
Fig. 1 is a schematic structural view of the tightening device of the present invention;
in the drawings, the 1-force rod; 2-a pin shaft; 3-semicircular jacket; 4-a cylindrical part to be assembled; 5-elastic gasket.
Detailed Description
The invention will be further described with reference to the accompanying drawings and examples.
Examples
As shown in fig. 1, the tightening device for a cylindrical member of the present invention comprises a semicircular clamping sleeve 3 and a force rod 1 connected to a free end of the semicircular clamping sleeve 3 through a pin 2, wherein the front end of the force rod 1 is a clamping plane; when the force rod 1 is turned to one side of the opening end of the semicircular jacket 3, the clamping plane at the front end of the force rod 1 and the inner wall of the semicircular jacket 3 clamp the cylindrical part to be assembled; when the force rod 1 is turned over towards the closed side of the semicircular jacket 3, the clamping plane at the front end of the force rod 1 and the inner wall of the semicircular jacket 3 loosen the cylindrical part to be assembled.
When the cylindrical part is screwed and assembled, the semicircular jacket 3 of the screwing device is sleeved on the outer wall of the cylindrical part to be assembled, the force rod 1 is turned towards one side of the opening end of the semicircular jacket 3, so that the clamping plane at the front end of the force rod 1 clamps the cylindrical part to be assembled inwards; and continuously overturning the force rod 1, and driving the cylindrical part to be assembled to synchronously rotate by the screwing device. When the cylindrical part is loosened, the force rod 1 is turned over to the closed side of the semicircular jacket 3, and the cylindrical part to be assembled is loosened by the clamping plane at the front end of the force rod 1 and the inner wall of the semicircular jacket 3, so that the screwing device can be separated from the cylindrical part to be assembled.
The inner side surface of the semicircular jacket 3 and the clamping plane at the front end of the force rod 1 are provided with elastic gaskets, so that the side wall of the cylindrical part to be assembled is prevented from being damaged by a screwing device.
Claims (2)
