Abstract

The utility model discloses an automatic drill press which can bore a plurality of holes on a circular mould at the same time. The automatic drill press comprises a drill press frame, a workpiece fixing base, a workpiece moving handle, a workpiece moving rack, an electromotor, an aiguille gearbox, a step motor gearbox and aiguilles. The automatic drill press is characterized in that the aiguilles are 1-5 in number and are evenly arranged on half of the side face of the circular mould workpiece; a servo motor connected with the aiguille gearbox is installed on the aiguille gearbox; the step motor gearbox and a step motor connected with the step motor gearbox are installed on a rotating shaft of the circular mould; and the servo motor and the step motor are connected through cables with a servo motor controller and a step motor controller which are arranged inside a control box. The automatic drill press has the advantages of reducing work intensity of the workers, improving drilling efficiency and effectively ensuring good hole machining quality on the circular mould.

Description

Porous is with jumping through rings mould automatic drilling machine

Technical field:

The utility model relates to a kind of rig, and particularly a kind of porous of annular workpieces boring that is used for is with jumping through rings mould automatic drilling machine.

Background technology:

The ring mould is a core component easy to wear in feed processing machinery.Current common ring mould rig is the conventional bench drill that includes a body, pedestal, support, back shaft, main shaft, drill bit etc., the ring mould is installed on the back shaft, stepping calibration by manual realization ring mould rotates, utilize main shaft chuck clamping drill bit, manual reciprocating feed, get out nib one by one, working (machining) efficiency is low, average 20 two days little time-divisions ability have been bored 7200 holes on the ring mould, labor strength is very big, this repeated labor causes fatigue easily, produces maloperation, and ring mould nib crudy can not get guaranteeing.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art, provides a kind of and can reduce labour intensity, improves drilling efficiency, can guarantee to encircle preferably the porous of mould nib crudy again with jumping through rings mould automatic drilling machine.

The utility model porous is with jumping through rings mould automatic drilling machine, mainly comprise drilling machine support, workpiece fixed pedestal, workpiece fixed support, work moving handle, motor, drill bit speed changer and drill bit, it is characterized in that: drill bit is 1～5, be evenly distributed on the half side-view of workpiece ring mould, on the drill bit speed changer, be fitted with the servomotor that is attached thereto, the stepper motor speed changer is set on the turning cylinder of workpiece ring mould and is attached thereto equipped stepper motor, servomotor and stepper motor are connected with controllor for step-by-step motor with servomotor controller in the control cabinet by cable.

Be provided with microcontroller in the described control cabinet case, with the system power supply that is connected with microcontroller, LCD and light-emitting diode display, audible-visual annunciator, supervisory keyboard, controllor for step-by-step motor, servomotor controller.

Described servomotor speed changer drives drill bit and moves up and down, and motor drives the drill bit rotary drilling by belt pulley.

This porous with the course of work of jumping through rings mould automatic drilling machine is: during work, the workpiece ring mould is fixed on the workpiece fixed support, by key in data, by the microcontroller output signal to stepper motor, the workpiece ring mould that the rotation of control step motor will be fixed on the workpiece fixed support turns on the original position, microcontroller output feeding this moment signal is to servomotor, drive the drill bit speed changer by servomotor, drill bit is moved up and down in the boring of workpiece ring mould repeatedly, the drill bit motor drives bit bore by belt pulley, the microcontroller output signal is to servomotor, rotate by the control servomotor, drive drill bit speed changer moves up drill bit and withdraws from workpiece ring mould nib district, export the calibration control signal then to stepper motor, the control step motor rotates, make the workpiece ring mould that is fixed on the workpiece fixed support rotate a stepping angle by the stepper motor speed changer, the location, repeat aforementioned microprocessor control process boring again, behind the intact circle hole of the rest may be inferred automatic drill, microcontroller output signal driving this moment audible-visual annunciator sends the sound and light alarm signal, the workman is the workpiece manipulation turning handle again, the workpiece fixed pedestal is moved to the distance of a regulation on slide rail, the workpiece ring mould is moved to the position of second circle, start microcontroller then, repeat aforementioned program control process and continue to bore the second circle hole.Repeat above-mentioned boring procedure like this, until getting out whole nibs.

The utility model has the advantages that: reduced labour intensity, the workman does not need manually frequent repeatable operation main shaft bit bore, groundwork is retainer ring mould and an installation drill bit before the boring, treats that drilling machine moves a secondary ring mould by back, the intact circle hole of the program control brill of microcontroller (approximately half an hour) by the workpiece moving handle; Improved drilling efficiency, a workman can supervise 4～5 ring mould automatic drilling machines simultaneously; By the microprocessor control boring procedure, the processing technology unanimity has effectively guaranteed to encircle preferably mould nib crudy.
