Abstract
Description
Technical Field
[0001] The utility model relates to the field of processing machinery, in particular to a pressing structure of a feeding mechanism of a precision grinding machine tool. Background Art
[0002] In the prior art, when processing precision parts, a material tray is generally used to send the workpiece to the processing area, and the workpiece is involved in the clamping process during the processing. For workpieces of different thicknesses (widths), not only the grinding parameters of the grinding wheel need to be adjusted, but also belts of different widths need to be selected. If the side of the belt protrudes from the grinding surface of the workpiece, the workpiece cannot be ground and the grinding wheel will grind the belt. In the process of replacing the belt, it is difficult to avoid the problem of position misalignment. Slight errors may not affect the processing, but when the workpiece size changes greatly, the belt position error may affect the processing process. Summary of the invention
[0003] The utility model adopts a tension wheel with adjustable position, and the position of the tension wheel can be adjusted laterally, thereby solving the technical problem in the prior art that the belt position error may affect the processing of the workpiece.
[0004] The utility model is designed to solve the above-mentioned technical problems and comprises a clamping device of a feeding mechanism of a precision grinding machine tool, which comprises a bracket, a circular material tray for conveying a workpiece to be ground and is installed on the bracket, an adjusting pulley, a tensioning pulley and an intermediate pulley are arranged in a triangular shape on the bracket, the pulley, the tensioning pulley and the intermediate pulley are connected by a belt, the tensioning pulley and the intermediate pulley are arranged across the upper and lower sides of the material tray, the belt between the tensioning pulley and the intermediate pulley is at least partially pressed on a partial circumference of the material tray, and the tensioning pulley is provided with an adjusting mechanism for controlling its lateral movement.
[0005] The regulating mechanism of the utility model is a tightening screw arranged on the tensioning belt pulley, or the regulating mechanism is an adjusting mechanism for controlling and locking the lateral movement of the rotating shaft of the tensioning belt pulley.
[0006] A further improvement of the utility model is that the adjusting pulley is movably mounted on the bracket via a crank-shaped rotating shaft, a locking mechanism is provided between the rotating shaft and the bracket, the locking mechanism is a locking screw arranged on the rotating shaft crank, or the locking mechanism is a locking screw arranged on the bracket.
[0007] The utility model adopts the above technical solution to adjust the lateral position of the belt, thereby avoiding the influence of the belt position error on the processing process, improving the yield rate and reducing the production cost. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a three-dimensional schematic diagram of the utility model.
[0009] Figure 2 It is a schematic diagram of the tensioner adjustment mechanism of the utility model.
[0010] Figure 3 It is a schematic diagram of the locking mechanism of the adjusting pulley of the utility model. DETAILED DESCRIPTION
[0011] The specific embodiments of the present utility model are described in conjunction with the above-mentioned drawings.
[0012] Depend on Figures 1 to 3 It can be seen that the clamping device of the feeding mechanism of the precision grinding machine designed by the utility model includes a bracket 10, and a circular material tray 20 for conveying the workpiece to be ground is installed on the bracket 10. The bracket 10 is provided with an adjusting pulley 11, a tensioning pulley 12 and an intermediate pulley 13 in a triangular shape. The pulley 11, the tensioning pulley 12 and the intermediate pulley 13 are connected by a belt 14. The tensioning pulley 12 and the intermediate pulley 13 are arranged on both sides of the upper and lower sides of the material tray 20. The belt between the tensioning pulley 12 and the intermediate pulley 13 is at least partially pressed on a part of the circumference of the material tray 20. The tensioning pulley 12 is provided with an adjusting mechanism 15 for controlling its lateral movement. The utility model adopts a method in which the tensioning pulley 12 can adjust its position laterally, which can avoid the phenomenon that the belt position error affects the processing process, improve the product yield rate, and reduce the cost.
[0013] Depend on Figure 2 It can be seen that the adjustment mechanism 15 is a tightening screw 151 arranged on the tensioning pulley 12. The tensioning pulley 12 is adjusted in position by hand. If the tensioning pulley 12 is fixed to the rotating shaft by tightening the tightening screw 151, the purpose of position locking is achieved.
[0014] The present invention can also be designed with a more complex adjustment mechanism. For example, the adjustment mechanism 15 is an adjustment mechanism for controlling and locking the lateral movement of the rotating shaft of the tensioning pulley 12. This method can use an adjustment screw set on the bracket, one end of which is connected to the bearing seat for installing the rotating shaft, and the other end is screwed to the bracket and locked with a spare nut (not shown in the figure).
[0015] Depend on Figure 3 It can be seen that the adjusting pulley 11 of the utility model is movably mounted on the bracket 10 through a crank-shaped rotating shaft 111, and a locking mechanism 112 is provided between the rotating shaft 111 and the bracket 10, and the locking mechanism 112 is a locking screw arranged on the crank of the rotating shaft 111, or the locking mechanism 112 is a locking screw arranged on the bracket 10. In this solution, the position of the adjusting pulley 11 is adjusted by rotating the crank-shaped rotating shaft to different positions to realize the function of belt tensioning. When adjusted into place, it is locked by the locking screw.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
