Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping machinery and equipment, specifically a special machine tool for milling, drilling, and chamfering the mounting base of a three-ton counterbalance forklift support cover. Background Technology

[0002] The three-ton counterbalance forklift support cover (referred to as the workpiece) is a semi-circular ring-shaped component with outwardly extending flat mounting seats at both ends. During processing, the workpiece mounting seats need to be milled, drilled, and chamfered on both sides of the drilled holes. The traditional processing method is to use four ordinary machine tools to clamp the workpiece in four separate operations, first milling and drilling, and then chamfering on both sides of the drilled holes. The disadvantages are that the operation is complicated and the work efficiency is low. Utility Model Content

[0003] This utility model addresses the problem of cumbersome operation and low work efficiency in processing three-ton counterbalance forklift support cover mounting bases using ordinary machine tools. It provides a machine tool that integrates milling, drilling, and chamfering for processing three-ton counterbalance forklift support cover mounting bases.

[0004] The technical solution of this utility model is a three-ton balance forklift support cover mounting machine, which is special in that a circular turntable is installed in the center of the flat worktable, a turntable motor is installed on the worktable outside the turntable, and six tooling seats are arranged on the outer perimeter of the turntable. Each tooling seat has two upper tooling columns arranged on the outer perimeter. Five workstations are arranged on the outer perimeter of the turntable, namely, a milling workstation at a clockwise 60-degree angle, a drilling workstation at a clockwise 120-degree angle, a chamfering workstation at a clockwise 180-degree angle, a flipping workstation at a clockwise 240-degree angle, and a reverse chamfering workstation at a clockwise 300-degree angle. The milling station, drilling station, chamfering station, and reverse chamfering station are all equipped with top-mounted square columns. Inside the square columns are two vertical guide rails, on which are mounted vertical slides. Outside the vertical slides, in the middle, is mounted a vertical lead screw. At the top of the lead screw is mounted a vertical motor, which is fixed to the top of the square column. Inside the vertical slides are two vertically arranged horizontal guide rails, on which are mounted horizontal slides. Outside the horizontal slides, in the middle, is mounted a horizontal lead screw. At one end of the lead screw is mounted a horizontal motor, which is fixed to one side of the vertical slide. Inside the horizontal slides are two vertical machine heads, on which are mounted machine head motors. Square columns at the drilling, chamfering, and reverse chamfering stations are fixed on the worktable. At the milling station, a radial slide plate is installed under the square column, and two radial guide rails are installed under the radial slide plate. A radial lead screw is installed between the two radial guide rails. The radial lead screw and the radial slide plate are connected by a nut. A radial motor is installed at the outer end of the radial lead screw, and the radial lead screw coincides with one of the diameters of the turntable. A robotic arm flipping module is installed at the flipping station.

[0005] During operation, first install the corresponding cutting heads under the vertical machine heads at the milling, drilling, chamfering, and reverse chamfering stations. Then, place the first workpiece (concave side down) on the fixture at the zero-degree position of the turntable. Start the turntable motor to rotate the turntable 60 degrees clockwise until it reaches the milling station, at which point the radial motor starts. Through the cooperation of the radial screw and radial guide rail, the radial slide and square column move radially inward along the turntable. When they reach the working position, the feed speed is switched (standby). Then, the vertical motor is started again. The vertical slide and vertical head are pushed downwards by the vertical lead screw and vertical guide rail. When they reach the working position, the vertical motor stops and the horizontal motor starts. The horizontal slide is pushed and pulled horizontally by the horizontal lead screw and horizontal guide rail, so that the milling cutters under the two vertical heads are aligned with the upper plane of the mounting seats at both ends of the workpiece and then stop. The head motor starts to drive the vertical head to work. After the milling is completed, the radial motor and vertical motor reverse and start to retract and reset. At the same time, the second workpiece is mounted on the tooling seat at the zero degree of the turntable.

[0006] The turntable motor is started, causing the turntable to rotate 60 degrees clockwise. The second workpiece stops at the milling station, where it is machined. Meanwhile, the first workpiece reaches the drilling station. The vertical motor of the drilling station starts, and through the cooperation of the vertical screw and vertical guide rail, it pushes the vertical slide and vertical head downward. When they reach the working position, the vertical motor switches to the feed speed (standby). The horizontal motor starts, and through the cooperation of the horizontal screw and horizontal guide rail, it pushes and pulls the horizontal slide to move horizontally, so that the drill bits under the two vertical heads are aligned with the drilling positions of the mounting seats at both ends of the workpiece. The head motor starts, driving the vertical head to drill. After drilling is completed, the head motor stops, and the vertical motor reverses direction and starts to retract and reset. At the same time, the third workpiece is mounted on the fixture at the zero degree of the turntable.

[0007] The turntable motor is started, causing the turntable to rotate 60 degrees clockwise. The third workpiece stops at the milling station, where it is machined. Meanwhile, the second workpiece arrives at the drilling station, where it is drilled. The first workpiece arrives at the chamfering station, where the vertical motor starts, and through the cooperation of the vertical screw and vertical guide rail, pushes the vertical slide and vertical head downwards. When they reach the working position, the vertical motor stops, and the horizontal motor starts, pushing and pulling the horizontal slide horizontally through the cooperation of the horizontal screw and horizontal guide rail. This aligns the drill bits under the two vertical heads with the pre-drilled holes at both ends of the workpiece. The head motor starts, driving the vertical head to chamfer. After chamfering is completed, the head motor stops, and the vertical motor reverses direction and starts to retract and reset. At the same time, the fourth workpiece is mounted on the fixture at the zero-degree position of the turntable.

[0008] The turntable motor is started, causing the turntable to rotate 60 degrees clockwise. The fourth workpiece stops at the milling station, where it is machined. At the same time, the third workpiece arrives at the drilling station, where it is drilled. The second workpiece arrives at the chamfering station, where it is chamfered. The first workpiece arrives at the flipping station, where the robot arm flipping module flips it 180 degrees (concave arc upwards), and the pre-drilled holes at both ends of the workpiece are fitted onto the tooling column. Simultaneously, the fifth workpiece is mounted on the tooling seat at the zero-degree position of the turntable.

[0009] The turntable motor is started, causing the turntable to rotate 60 degrees clockwise. The fifth workpiece stops at the milling station, where it is processed. Meanwhile, the fourth workpiece arrives at the drilling station, where it is drilled. The third workpiece arrives at the chamfering station, where it is chamfered. The second workpiece arrives at the flipping station, where the robot flipping module flips it. The first workpiece arrives at the reverse chamfering station, where the vertical motor starts, using a vertical screw and guide rail to push the vertical slide and vertical head downwards. When they reach the working position, the vertical motor stops, and the horizontal motor starts, using a horizontal screw and guide rail to push and pull the horizontal slide horizontally, aligning the drill bits under the two vertical heads with the other ends of the pre-drilled holes on the workpiece. The head motor starts, driving the vertical head to chamfer. After chamfering, the head motor stops, and the vertical motor reverses direction and starts to retract and reset. At the same time, the sixth workpiece is mounted on the fixture at the zero-degree position of the turntable.

[0010] The turntable motor is started, causing the turntable to rotate 60 degrees clockwise. The sixth workpiece stops at the milling station, where it is machined. Meanwhile, the fifth workpiece arrives at the drilling station, where it is drilled. The fourth workpiece arrives at the chamfering station, where it is chamfered. The third workpiece arrives at the chamfering and flipping station, where the robot flipping module flips it. The second workpiece arrives at the reverse chamfering station, where it is chamfered at the other end. The first workpiece and fixture arrive at the zero-degree position of the turntable. The first workpiece is removed and the seventh workpiece is installed, and the cycle continues continuously.

[0011] The technical advantage of this invention is that, by adopting the above-mentioned technical solution, a machining tool for a three-ton counterbalanced forklift support cover mounting base can be realized, which is convenient to operate and has extremely high working efficiency. It completes four processes—milling, drilling, and chamfering on both sides—in a single clamping and fixing of the workpiece, reducing the hassle of workpiece clamping and disassembly, saving time, and accelerating production speed.
