Problems solved by technology

like image 3 The guide chute on the carriage is a T-shaped groove. With this structure, during use, the contact surface between the guide chute on the carriage and the beam guide rail will be worn away, resulting in a fault on one side and the bottom of the T-shaped groove. Clearance, in the process of processing, because there is a gap between the guide chute on the carriage and the contact surface of the beam guide rail, this will cause the carriage to shake in the Y-axis and Z-axis directions when it moves along the beam guide rail, thus Affect the shape accuracy, position accuracy, dimensional accuracy and surface roughness of the workpiece, so that the final processed workpiece cannot meet the use requirements

no. 1 approach

[0022] Such as figure 1 , figure 2 , Figure 4 and Figure 5 The sliding structure of the machine tool pallet shown includes a beam 1 and a pallet 2; the beam 1 is provided with a guide rail 3, and the pallet 2 is provided with two guide grooves 4 that can slide along the guide rail 3; The main shaft head 5 is installed; the top 20 of the guide groove 4 has a slope 6 downward, and the top 20 grooves of the two guide grooves 4 face the same direction; the guide rail 3 is a plane 30 corresponding to the top 20 of the guide groove 4 .

[0023] Such as Figure 4 and Figure 6 As shown, a guide slide 15 is installed on the top of the carriage 2, and the guide slide groove 4 positioned at the top of the carriage 2 is composed of the slope 6 and a side 151 of the guide slide 15, and the side 151 of the guide slide 15 is in contact with the vertical surface. The size of the included angle is-15-30 °, in the present embodiment, the included angle is 0 °; An included angle of 0°...

[0028] Such as figure 1 , figure 2 , Figure 7 The sliding structure of the machine tool pallet shown includes a beam 1 and a pallet 2; the beam 1 is provided with a guide rail 3, and the pallet 2 is provided with two guide grooves 4 that can slide along the guide rail 3; The main shaft head 5 is installed; the top 20 of the guide groove 4 has a slope 6 downward, and the top 20 grooves of the two guide grooves 4 face the same direction; the guide rail 3 is a plane 30 corresponding to the top 20 of the guide groove 4 . Such as Figure 7 As shown, an inclined surface 12 is also provided on the carriage. When the carriage 2 tends to tilt due to gravity, the inclined surface 12 has a restrictive effect on the carriage 2. In this way, the carriage 2 can be better prevented from detaching from the guide rail 3. .

[0029] A fixed plate 7 is fixedly installed on the lower surface of the carriage 2, and one end of the fixed plate 7 breaks away from the abutment 71 of the guide r...

no. 3 approach

[0033] Such as figure 1 , figure 2 and Figure 8 The sliding structure of the machine tool pallet shown includes a beam 1 and a pallet 2; the beam 1 is provided with a guide rail 3, and the pallet 2 is provided with two guide grooves 4 that can slide along the guide rail 3; The main shaft head 5 is installed; the top 20 of the guide chute 4 has a slope 6 and another second slope 13 downwards, and the angle between the second slope 13 and the vertical plane is 30-90°. In this embodiment , the included angle is 45°, and the tops 20 of the two guide grooves 4 face the same direction; the guide rail 3 corresponds to a plane 30 at the top 20 of the guide grooves 4 .

[0034] A fixed plate 7 is fixedly installed on the lower surface of the carriage 2, and one end of the fixed plate 7 breaks away from the abutment 71 of the guide rail 3 for preventing the carriage from jumping upwards, which improves the safety of the machine tool.

Abstract

The invention discloses a machine tool dragging plate slide structure, which comprises a cross beam and a dragging plate, wherein a guide rail is arranged on the cross beam, a main shaft head is arranged on the dragging plate, two guide slide grooves capable of sliding along the guide rail are arranged on the dragging plate, an inclined surface is downwards arranged at the top end of the guide slide grooves, top end grooves of the two guide slide grooves face the same direction, the inclined surface is a contact surface of the dragging plate and the guide rail, and the dragging plate is pressed on the guide rail through the contact surface. The invention is used for averagely dividing the abrasion of the dragging plate in the X-axis direction and in the Y-axis direction, in addition, the averagely divided abrasion is in the same direction, so no gap is generated, the dragging plate does not shake, and the quality of processed work pieces can be improved.

Description

technical field [0001] The invention relates to a sliding structure of the carriage of a machine tool, in particular to the sliding structure of the carriage on milling machines, boring machines and grinding machines. Background technique [0002] In mechanical processing, milling machines, boring machines, and grinding machines are widely used. Milling machines are mainly used to process grooves and plane parts, and boring machines are mainly used to fine-boring holes. Milling machines, horizontal milling machines, tool milling machines, small boring machines or grinding machines are processed, while medium and large parts are generally processed on large machine tools, mainly composed of bed, column, workbench, beam and carriage. A spindle head is installed on the carriage, and the carriage can move along the X-axis direction on the beam, the spindle head can move in the Z-axis direction, and the workbench can move in the Y-axis direction, so that the machine tool can be m...
