Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of engraving and milling machine accessories, and particularly to a high-performance spraying device for an engraving and milling machine. BACKGROUND

[0002] An engraving and milling machine is a kind of numerical control machine tool. Traditional engraving machines are difficult to process workpieces with high hardness, and milling machines are difficult to process small workpieces with small cutters. The emergence of the engraving and milling machine fills the gap between the two, and it can both engrave and mill. When the engraving and milling machine encounters some special reasons, such as high material hardness and material intolerance to high temperature, a spraying device is needed to spray cutting fluid to carry away the heat on the surface of the workpiece and the cutter.

[0003] The spraying device for the high-performance numerical control engraving and milling machine with the application number 202222053076.3 sprays liquid on the engraving and milling cutter that is being engraved and milled, thereby playing a role in cooling and buffering. The spraying pipe is adjusted in angle by means of the electric push rod and the adjusting device, improving flexibility and overcoming the problem of great limitations. The spraying device comprises a workbench, two vertical rods, a top plate, an engraving and milling machine body, a lifting plate, a vertical plate, an adjusting plate, a spraying head, an electric push rod, a plurality of through holes, an adjusting mechanism, and a liquid supply mechanism. The workbench is horizontally placed, and a plurality of through holes are arranged in the middle part of the workbench. The two vertical rods are vertically installed at the top end of the workbench, and the top plate is horizontally and fixedly installed at the top end of the two vertical rods. The engraving and milling machine body is installed at the bottom end of the top plate. The top end of the lifting plate is fixedly connected with the output end of the electric push rod, and the bottom end of the lifting plate is provided with a strip-shaped groove. The adjusting mechanism is arranged in the strip-shaped groove.

[0004] Although the technical solution is convenient for adjusting the vertical height and the vertical angle, the engraving and milling machine generally operates at least three axes, namely front and rear translation, left and right translation, and up and down lifting. The technical solution can only adjust the lifting and left and right translation of the engraving and milling machine. When the cutter or the workpiece of the engraving and milling machine translates forward and backward or deflects at a certain angle, it is difficult to spray the cutting point. INVENTION CONTENTS

[0005] Therefore, the utility model aims to provide a high-performance spraying device for an engraving and milling machine to solve the technical problems mentioned in the background.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A spraying device for a high-performance engraving and milling machine, including a device main body and a card seat. An electric cylinder is installed on the top of the device main body. A first motor is installed on one side inside the device main body, and a first straight gear is connected to the output end of the first motor. A retaining sleeve is connected to the outer surface of the device main body, and an adjustment box is connected to the bottom of the retaining sleeve through a support sleeve. A second straight gear is fixed on the top of the adjustment box. A second bevel gear is connected inside the adjustment box. A first retaining ring is fixed on one side of the adjustment box. A second motor is installed above the inside of the device main body, and a first bevel gear is connected to the output end of the second motor. A second retaining ring is fixed on one side of the card seat.

[0007] By adopting the above technical solutions, the height of the spray head is adjusted by the motor. After the first motor is started, the adjustment box is driven to rotate left and right through the meshing of the first straight gear and the second straight gear, thereby adjusting the horizontal angle of the spray head. After the second motor is started, the card seat is driven to rotate up and down through the meshing of the first bevel gear and the second bevel gear, thereby adjusting the vertical height of the spray head. The rotating parts are blocked by the adjustment box, the support sleeve, the retaining sleeve, the first retaining ring and the second retaining ring, avoiding debris from entering and increasing structural wear.

[0008] Further, the first straight gear meshes with the second straight gear, and the first bevel gear meshes with the second bevel gear.

[0009] By adopting the above technical solutions, after the first motor is started, the output end drives the adjustment box to rotate left and right through the meshing of the first straight gear and the second straight gear, thereby adjusting the left and right angles of the spray head. At the same time, the second motor drives the first bevel gear to rotate, making the first bevel gear and the second bevel gear relatively stationary, avoiding the phenomenon that the second bevel gear rotates while the first bevel gear remains stationary, resulting in the up and down rotation of the spray head.

[0010] Further, the cross-section of the support sleeve is in an inverted "r" shape, and the support sleeve is rotatably connected to the retaining sleeve.

[0011] By adopting the above technical solutions, the adjustment box is supported through the cooperation of the retaining sleeve and the support sleeve. At the same time, the distance between the bottom of the retaining sleeve and the support sleeve is relatively large, which can block the impurities flying towards the support sleeve, reducing the entry of impurities into the gaps of the horizontal rotating structure and increasing wear and resistance.

[0012] Further, there is a gap between the retaining sleeve and the adjustment box.

[0013] By adopting the above technical solutions, there is a gap between the retaining sleeve and the adjustment box, avoiding impurities being stuck between the retaining sleeve and the adjustment box and increasing wear and resistance.

[0014] Further, the outer ring of the first retaining ring is in a slope shape, and the inner ring of the second retaining ring is in a slope shape.

[0015] By adopting the technical scheme, in the process of engraving and milling, the first blocking ring outer ring is inclined and the second blocking ring inner ring is inclined, so that the entering debris can be guided outwards, and the impurities entering the gap of the vertical rotating structure are reduced to increase the abrasion and resistance.

[0016] Further, the first motor and the second motor are both servo motors.

[0017] By adopting the technical scheme, since the first motor and the second motor are both servo motors, the vertical angle and the horizontal angle of the spray head can be accurately adjusted.

[0018] Further, the clamping seat is connected to one side of the second bevel gear, and the outer surface of the clamping seat penetrates the spray head.

[0019] By adopting the technical scheme, the worker installs the electric cylinder above the inside of the engraving and milling machine, then connects the hose conveying the cutting fluid to the back of the spray head, and sprays the position of the workpiece being engraved and milled by the spray head, so as to facilitate heat dissipation of the workpiece and the cutter.

[0020] Further, the clamping seat penetrates the fastening bolt on one side, and the fastening bolt abuts against the spray head.

[0021] By adopting the technical scheme, the worker inserts the spray head into the clamping seat and tightens the fastening bolt, so as to limit the spray head.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model discloses a structure that comprises an electric cylinder, a first motor, a second motor, a supporting sleeve, a blocking sleeve, a first blocking ring and a second blocking ring. The height of the spray head is adjusted by the motor. After the first motor is started, the first spur gear and the second spur gear are engaged to drive the adjusting box to rotate left and right, so as to adjust the horizontal angle of the spray head. After the second motor is started, the first bevel gear and the second bevel gear are engaged to drive the clamping seat to rotate up and down, so as to adjust the vertical height of the spray head. The rotating part is shielded by the adjusting box, the supporting sleeve, the blocking sleeve, the first blocking ring and the second blocking ring, so as to avoid the debris from entering to increase the structural abrasion. The structure is more flexible and can shield the debris to avoid affecting the rotation of the device. BRIEF DESCRIPTION OF DRAWINGS
