Technical Field

The invention relates to the field of production equipment, in particular to a workpiece straightening device of a single-side power conveying line.

Background

As the lean production concept is gradually popularized, a single-side power transmission line (refer to fig. 1) is provided in an existing factory, and the transmission line is applied to various production environments. For example, in the field of automobile production, for conveying skids for fixing vehicle shells. The conveying line comprises supporting rails which are respectively positioned on two sides, wherein an annular driving belt is arranged on the supporting rail on one side, a skid is hung on the annular driving belt during use, and the skid moves by means of friction force between the skid and the annular driving belt. The conveying line is simple in structure, the driving motor only needs to load the weight of the narrow guide rail on one side during operation, and the conveying line has the characteristics of energy conservation and high efficiency. However, when the power of the conveyor line is output on one side, the skid is easy to rotate around the unpowered side, so that the center of gravity of the skid is far away from the annular driving belt (refer to fig. 2), the friction force between the skid and the annular driving belt is reduced, and the skid cannot slide. The existing improvement method is to arrange guide wheels on two sides of a conveying line to straighten a skid, but the size of the skid is large, so that the guide wheels and the skid are difficult to avoid deviation, and the actual using effect of the guide wheels is not good.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: provides a workpiece straightening device of a single-side power conveying line.

The solution of the invention for solving the technical problem is as follows:

unilateral power transfer chain work piece straightener includes:

the bracket is arranged on the top surface of the first base block, the bracket penetrates through the first base block from front to back, and a first rotating shaft, a second rotating shaft and a first bump are arranged on the right side of the first base block;

one side of the straightening rotating arm is hinged with the first rotating shaft, the other side of the straightening rotating arm is provided with a straightening block extending out from the left side, and one side of the straightening block, which is close to the bracket, is provided with a straightening surface;

and the torsional spring provides upward rotating force for the straightening rotating arm by virtue of the first lug.

The invention has the beneficial effects that: when the straightening device is used, the plurality of straightening devices are fixed on an external conveying line through the first base block, an external workpiece is hoisted to the conveying line from the upper side, the workpiece can fall above the straightening block due to the fact that the conveying line continuously flows, the straightening block can rotate downwards to avoid the workpiece from being erected by the straightening block due to the arrangement of the torsion spring, and the workpiece can move on the bracket along with the external conveying line; when the peripheral workpiece rotates on one side, the peripheral workpiece is kept still under the condition that the peripheral conveying line continues to move until encountering a straightening block on another straightening device, a straightening surface on the straightening block is abutted against the workpiece, the direction of the workpiece is corrected, and the workpiece is abutted against the workpiece and moves along with the conveying belt; under the condition that the straightening block abuts against the workpiece to travel, when the workpiece moves to the limiting position on the conveying belt and cannot move continuously along with the conveying belt, the straightening rotating arm can rotate downwards under the action of the torsion spring, the straightening block retracts to the lower side of the workpiece, the conveying belt can move continuously, and the continuous conveying of the workpiece cannot be influenced.

As a further improvement of the above technical solution, in order to facilitate straightening of a conventional square member, the straightening surface is perpendicular to the extension direction of the bracket.

As a further improvement of the technical scheme, in order to avoid that the straightening block cannot rotate because the force of the workpiece acting on the straightening block points to the center of the first rotating shaft when the workpiece slides on the bracket and meets the straightening block, the first rotating shaft is arranged below the bracket.

As a further improvement of the above technical solution, a pin hole is provided at one side of the first protrusion near the first rotating shaft, and a leg of the torsion spring extends into the pin hole. Therefore, the support legs of the torsion spring can be better supported when extending into the first convex blocks.

As a further improvement of the above technical scheme, the first base block is further provided with arm connecting holes arranged on the left and right sides, the bottom surface of the bracket is provided with an ejection hole, and the ejection hole is communicated with the arm connecting holes; an extension arm is fixedly connected to the first bump, a pressing block is fixedly connected to the top surface of the extension arm and slides up and down, a spring is arranged between the bottom surface of the extension arm and the bottom surface of the arm connecting hole, and the pressing block is jacked up by the spring and at least partially exceeds the bottom surface of the bracket. Torsional spring, straightening rocking arm, aligning piece and pivot set up, the work piece that on the one hand needs to satisfy the peripheral hardware can the downwardly rotating when falling to the aligning piece from the top, and on the other hand, when the work piece slides on holding in the palm the groove and meets the aligning piece, the aligning piece can not rotate, needs butt work piece continuous movement. This places high demands on the accuracy of the torsion spring force, especially for some workpieces of lighter weight. The pressing block is arranged in the further improvement scheme, the pressing block is connected with the first lug through the extension arm, when a workpiece is pressed on the bracket, the support legs of the torsion spring on the first lug are pressed to move downwards, and the torsion spring provides larger torsional force for the straightening rotating arm, so that when the workpiece slides on the bracket and meets the straightening block, the straightening block is not easy to rotate, and the straightening block can be better guaranteed to be capable of supporting the workpiece to move.

As a further improvement of the above technical solution, in order to make the spring not easily come off, the bottom surface of the extension arm is provided with a first groove, the top surface of the spring abuts against the first groove, and the bottom surface of the spring abuts against the arm connecting hole.
