Description

CNC Vertical Axis Rectangular Table Surface Grinder

technical field

The utility model belongs to a kind of mechanical processing equipment, in particular to a numerically controlled vertical axis rectangular table surface grinder. .

Background technique

The workbench of the original vertical axis rectangular table surface grinder is operated by the hydraulic system to realize the reciprocating motion by the double piston rod hydraulic cylinder. The hydraulic cylinder is fixed on the workbench, and the two sides of the double piston rod are fixed on the bed. sports. The speed of the workbench is manually adjusted by the speed control valve on the hydraulic system. The adjusted speed depends on the work experience and technical level of the operator to adjust the speed close to the required speed of the workpiece. The workbench and the bed are combined with V-shaped guide rails and flat guide rails, and the lubricating oil is provided by the hydraulic system. In the reversing and reciprocating operation intervals of the workbench, the operator must adjust the two bumpers on the side of the workbench. The bumper slides and locks along the T-shaped groove of the workbench. The bumper hits the reversing device on the bed to make the workbench When reversing, the vibration is large and the position is not accurate. It must be adjusted twice to three times to approximately meet the requirements of the reversing position. Work efficiency is low. There are two types of up and down movement of the grinding head, manual feed and rapid feed. The grinding head is fixed on the slide plate, the screw nut is fixed on the slide plate, and the lead screw is fixed on the lower end of the column. It is connected with the worm gear of the reduction box through the cross coupling, decelerated by the worm gear, and the reduction box is fixed on the column. The front and rear of the worm are respectively equipped with tooth clutches, and the tooth clutches slide back and forth through the sliding of the splines. Under normal circumstances, the front tooth type clutch is engaged with the manual feeding device, and the slide plate is moved up and down to grind the workpiece through the hand wheel. Fast feeding and fast leaving are through moving the handle up and down quickly, pushing the tooth type clutch through the cam mechanism to drag the front tooth type clutch away and the rear tooth type clutch to engage, and the fast motor rotation makes the slide plate move up and down quickly. The dog clutch is returned by spring. The trimming of sand tiles is done by hand.

The disadvantages are: to adjust the speed of the workbench, the hydraulic speed control valve must be manually operated to adjust the speed, and the grinding speed approximate to the workpiece needs to be adjusted based on the operator's work experience and technical level. The vibration of the workbench is large when the direction is changed. When grinding the workpiece, it is approached by a fast motor and adjusted manually. Work efficiency is low.

Contents of the invention

The purpose of the utility model is to provide a numerically controlled vertical axis rectangular table surface grinder, which realizes numerically controlled operation, is convenient to adjust, significantly improves work efficiency and machining accuracy, is safe and reliable to operate, and improves the protection of machine operators.

The specific technical scheme provided by the utility model is as follows: it includes a bed, a workbench, a column, a slide plate, a sand tile and a numerical control system, and is characterized in that: the sand tile is fixed on the main shaft of the slide plate, the frequency conversion motor is fixed on the slide plate, and the numerical control The servo motor is fixed on the slide plate; the servo motor is connected with the ball screw through a coupling, and the screw base is fixed on the column; the CNC servo motor is connected with the ball screw through a coupling, and the screw base is fixed on the workbench.

The utility model has the advantages of realizing numerical control operation and convenient adjustment, the adjustment of the running speed of the workbench and the reciprocating running interval of the reversing operation can be adjusted through the numerical control system at one time, and the running speed and reversing position are accurate, and the workpiece needs to be ground after accurate adjustment. The speed, the commutation is smooth. Improve the accuracy and production efficiency of the workpiece. The rapid lifting of the grinding head and the return to the manually set reference point through the numerical control system when grinding the workpiece quickly approach the workpiece and grind the workpiece, which significantly improves the production efficiency. The operation is safe and reliable, which improves the protection of machine operators.

Detailed ways

The concrete structure of the utility model is as follows: see Fig. 1, sand tile 2 is fixed on the main shaft of slide plate 3, and frequency conversion motor 4 is fixed on the slide plate 3, drives the slide plate main shaft to make sand tile rotate thereby grinding workpiece. The servo motor 5 is fixed on the slide plate 3 through the bracket 6 , the servo motor 5 is connected with the ball screw 9 through the shaft coupling 7 , the screw nut seat 8 is fixed on the column 11 , and the column is fixed on the bed 12 . The servo motor 5 realizes the movement of the grinding head up and down through the numerical control system. The micro-feeding and rapid lifting of the grinding head when grinding the workpiece can be operated on the TFT screen, which can quickly move the grinding head to the working position. Work efficiency increased by 3-4 times. See Fig. 2, servomotor 13 is connected ball screw 15 by shaft coupling 14, and workbench 16 operation is to be that servo motor 13 drives ball screw 15 to rotate by shaft coupling 14, and the nut base is fixed on workbench 16. The workbench 16 and the bed adopt existing linear guide rails, and the numerical control system controls the servo motor 13 to realize the reciprocating motion of the workbench through the numerical control system. Stable operation, precise reversing, accurate and convenient speed regulation.
