Description
Technical Field
The invention relates to a positioning fixture, in particular to a positioning fixture for sawing cylindrical workpieces.
Background
The cylindrical workpieces and jacks mostly adopt a clamping key type structure, the work efficiency of the operation of milling and cutting single pieces equally by the clamping key is very low, and in order to greatly improve the production efficiency and the product quality, a belt type sawing machine is fully utilized, and the production cost is reduced, so that the clamping tool is adopted to fix the cylindrical workpieces and then the sawing machine is convenient to saw; but current positioning fixture is fairly simple, and it not only destroys the work piece excircle surface easily in the use, and because its relatively poor position precision that leads to the sawing of stability is lower moreover to influenced the qualification rate of work piece, how to provide one kind and to enable the work piece fixed back stability higher, guarantee the positioning fixture of the work piece qualification rate after the processing is the problem that this trade needs to solve urgently.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a positioning fixture for sawing cylindrical workpieces, which can effectively solve the problems.
In order to achieve the purpose, the invention adopts the technical scheme that: a positioning fixture for sawing cylindrical workpieces comprises a bottom plate, a connecting plate, a supporting rod fixing plate, a supporting rod, a diameter adjusting plate, a clamping plate and a tensioning screw rod, wherein the bottom plate is a rectangular plate, a lower plane is arranged on a machine tool, and one end of an upper plane is vertically welded and fixed with the connecting plate; a through hole is formed in the center of the connecting plate, a circular groove is formed in one surface, which is attached to the supporting rod fixing plate, and a locking nut of the supporting rod can be embedded in the circular groove; the supporting rod fixing plate is a circular plate, a hole is formed in the center of the supporting rod fixing plate and used for outwards radiating through a tensioning screw rod by taking the center as a base point on a plane, and a long hole is formed in each three-degree angle and used for installing the supporting rod and enabling the supporting rod to slide in the long hole to achieve diameter adjustment; the two end faces and the central hole are respectively provided with a cylindrical boss concentrically, and the boss at one end is provided with an external thread; one end of the screw thread is embedded into the central hole of the fixing plate, and the connecting plate and the supporting rod fixing plate can rotate relatively; a diameter adjusting plate is arranged on the boss at the other end; the diameter adjusting plate is provided with a hole at the center, and the hole is arranged on the supporting and fixing plate.
Further, the connecting plate is made of alloy materials.
Furthermore, spiral arc-shaped long holes are formed in the surface of the supporting and fixing plate in three degrees.
The invention combines the bottom plate, the connecting plate, the supporting rod fixing plate, the supporting rod, the diameter adjusting plate, the clamping plate and the tensioning screw, so that the stability of the fixed workpiece is higher, and the qualified rate of the processed workpiece is ensured.

Detailed Description
The present invention will be further explained below.
As shown in figure 1, the invention comprises a bottom plate, a connecting plate, a supporting rod fixing plate, a supporting rod, a diameter adjusting plate, a clamping plate and a tensioning screw rod, wherein the bottom plate is a rectangular plate, the lower plane is arranged on a machine tool, and one end of the upper plane is vertically welded and fixed with the connecting plate; a through hole is formed in the center of the connecting plate, a circular groove is formed in one surface, which is attached to the supporting rod fixing plate, and a locking nut of the supporting rod can be embedded in the circular groove; the supporting rod fixing plate is a circular plate, a hole is formed in the center of the supporting rod fixing plate and used for outwards radiating through a tensioning screw rod by taking the center as a base point on a plane, and a long hole is formed in each three-degree angle and used for installing the supporting rod and enabling the supporting rod to slide in the long hole to achieve diameter adjustment; the two end faces and the central hole are respectively provided with a cylindrical boss concentrically, and the boss at one end is provided with an external thread; one end of the screw thread is embedded into the central hole of the fixing plate, and the connecting plate and the supporting rod fixing plate can rotate relatively; a diameter adjusting plate is arranged on the boss at the other end; the diameter adjusting plate is provided with a hole at the center, and the hole is arranged on the supporting and fixing plate.
Further, the connecting plate is made of alloy materials.
Furthermore, spiral arc-shaped long holes are formed in the surface of the supporting and fixing plate in three degrees.
During operation, the bottom plate is installed on a sliding table or a workbench of a machine tool, the locking nut of the supporting rod is loosened, the diameter adjusting plate is rotated, the supporting rod moves along the long hole in the diameter adjusting plate to reach a preset diameter, and the supporting rod nut is locked to move the diameter adjusting plate to the fixing ring on one side of the clamping plate. And (4) mounting a cylindrical workpiece, adjusting the indexing positioning pin, locking the tension rod, and processing. One step is completed, the indexing locating pin is loosened, the workpiece is rotated, and the other indexing is achieved and the locking is carried out. The process continues. And after all the workpieces are processed, loosening the clamping plate and taking down the workpieces. One cycle of operation ends.
