Description

Technical Field

[0001] The utility model relates to the technical field of CNC machine tools, in particular to a spindle isolation door for a heavy-duty gantry CNC machine tool for milling. Background Art

[0002] With the continuous advancement of machining technology, various types of CNC machine tools have been designed and put into use. To increase the speed of workpiece processing, dual-spindle CNC machine tools have come into use. For example, heavy-duty gantry CNC milling machines equipped with a 3D printing spindle head and a milling spindle head have been put into use. Because the spindle head is a key component of CNC machine tools, they are equipped with a corresponding storage chamber and an isolation door. Closing the isolation door during machining or when cleaning the worktable effectively prevents chips and chip fluid generated by the machine tool from splashing into the storage chamber, effectively isolating and protecting the spindle head.

[0003] However, since the chips generated by CNC machine tools during the grinding and milling process contain some granular and mixed chip liquid, they are easy to splash and adhere to the gap between the isolation door and the door frame, causing the isolation door to be unable to open normally, which is very troublesome.

[0004] Therefore, the research purpose of this utility model is to design a spindle isolation door for heavy-duty gantry CNC machine tools that can automatically, effectively and timely remove chips from sticky surfaces, thereby effectively preventing chip blockage and ensuring normal use. Utility Model Content

[0005] In response to the technical problems existing in the above-mentioned prior art, the present invention provides a spindle isolation door for heavy-duty gantry CNC machine tools for grinding and milling, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A spindle isolation door for a heavy-duty gantry CNC machine tool for milling and grinding, comprising:

[0008] door frame;

[0009] An isolation door panel is mounted on the door frame and can be moved up and down and swung back and forth and is used to close the door frame. A corresponding counterweight is mounted on the bottom of the isolation door panel.

[0010] The guide mechanism comprises two guide groove members symmetrically fixedly mounted on both sides of the door frame and having an L-shaped cross section, and the two side edges and the front side of the isolation door panel are spaced apart from the side walls of the guide groove members; the drive mechanism is used to drive the isolation door panel to move up and down, and is hinged to the top of the isolation door panel;

[0011] The scraping mechanism is arranged on the lower front side of the isolation door panel. When the isolation door panel moves downward, the outer side wall thereof contacts the scraping mechanism.

[0012] The inner side spacing of the two guide groove members is greater than the width of the isolation door panel, and the spacing between the side of the guide groove member and the door frame is greater than the thickness of the isolation door panel, and the isolation door panel and the door frame are set at a spacing.

[0013] The driving mechanism includes a base fixedly connected to the lower inner side of the door frame, a corresponding hydraulic cylinder is upright and fixedly installed on the base, the end of the piston rod of the hydraulic cylinder is installed with a corresponding ear seat through a transversely fixed connecting plate, and the top of the isolation door panel is fixed with an ear plate that is compatible with the ear seat. By inserting a connecting rod connecting the ear plate and the ear seat, the isolation door panel can be swung back and forth and installed under the connecting plate.

[0014] The scraping mechanism includes a scraping plate obliquely arranged on the lower front side of the counterweight block, the outer side surface of the counterweight block is arranged as an inwardly inclined surface, and the end of the scraping plate abuts against the inclined surface.

[0015] The scraper plate is made of rubber or plastic.

[0016] The isolation door panel is a hollow and lightweight door body.

[0017] A corresponding sensor is provided on the inner side of the top of the door frame. The sensor senses the movement of the main shaft and transmits a signal. The drive mechanism is actuated to drive the isolation door panel to move downward.

[0018] Advantages of this utility model:

[0019] 1) The utility model utilizes a driving mechanism to drive the isolation door panel to move up and down, and cooperates with a scraper plate abutting the isolation door panel, which helps to automatically scrape off the chips and chip liquid adhering to the isolation door panel while ensuring a stable installation and driving the isolation door panel to move.

[0020] 2) However, only by cooperating with the isolation door panel that moves up and down through the scraper plate, only the chips and chip liquid on the surface of the isolation door panel can be removed. The problem of chips and chip liquid in the gap between the isolation door panel and the door frame cannot be solved. Therefore, the present invention effectively prevents chips from sticking and clogging, thereby affecting the normal opening of the isolation door panel, and avoids chips from causing wear on the isolation door panel when the isolation door panel moves up and down, by spacing the isolation door panel and the guide mechanism. However, simply setting the spacing will still cause clogging problems after long-term use. Therefore, the present invention further installs the isolation door panel in a hinged manner under the premise that the hydraulic cylinder fixes and drives the isolation door panel, and adds a counterweight block to the isolation door panel. On the basis of ensuring that the shielding effect of the isolation door panel on the door frame remains unchanged, the isolation door panel is used to collide with the scraper plate when it moves down, causing shaking. Under the action of kinetic energy, it is more conducive to material shedding, and the chips in the gap are not easy to stick during the shaking process and fall as the isolation door panel moves up and down.

[0021] 3) The utility model utilizes an inclined scraper plate, assisted by the upward and downward movement of the isolation door panel and the resulting oscillation, to facilitate the automatic removal of chips, effectively preventing chips from sticking to the isolation door panel and affecting its movement. Furthermore, the outer side of the counterweight is tilted, ensuring the isolation door panel is vertical during ascent. The inclined surface acts as a guide during descent, allowing the isolation door panel to deform and tilt, further enhancing the scraping effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0028] refer to Figure 1-4 , a spindle isolation door for a heavy-duty gantry CNC machine tool for milling and grinding, comprising:

[0029] Door frame 1;

[0030] An isolation door panel 2 is mounted on the door frame 1 and can be moved up and down and swung back and forth to close the door frame 1. A corresponding counterweight 3 is mounted on the bottom of the isolation door panel 2.

[0031] The guide mechanism comprises two guide groove members 4 symmetrically fixedly mounted on both sides of the door frame 1 and having an L-shaped cross section, and the two side edges and the front side of the isolation door panel 2 are spaced apart from the side walls of the guide groove members 4; the drive mechanism is used to drive the isolation door panel 2 to move up and down, and is hinged to the top of the isolation door panel 2;

[0032] The scraping mechanism is arranged at the lower front side of the isolation door panel 2. When the isolation door panel 2 moves downward, the outer side wall thereof contacts the scraping mechanism.

[0033] The utility model utilizes a driving mechanism to drive the isolation door panel 2 to move up and down, and cooperates with the scraper plate 10 abutting the isolation door panel 2, which helps to automatically scrape off the chips and chip liquid adhering to the isolation door panel 2 while ensuring a stable installation and driving the isolation door panel 2 to move.

[0034] However, only by cooperating with the scraper plate 10 and the isolation door panel 2 that moves up and down, the chips and chip liquid on the surface of the isolation door panel 2 can be removed. The chips and chip liquid in the gap between the isolation door panel 2 and the door frame 1 cannot be solved. Therefore, the present invention effectively prevents chips from sticking and clogging, thereby affecting the normal opening of the isolation door panel 2, and avoids chips from causing wear on the isolation door panel 2 when the isolation door panel 2 moves up and down, by setting the isolation door panel 2 and the guide mechanism at intervals. However, simply setting the intervals will still cause clogging problems after long-term use. Therefore, the present invention further installs the isolation door panel 2 in a hinged manner under the premise that the hydraulic cylinder fixes and drives the isolation door panel 2, and adds a counterweight block 3 to the isolation door panel. On the basis of ensuring that the shielding effect of the isolation door panel 2 on the door frame 1 remains unchanged, the isolation door panel 2 is used to collide with the scraper plate 10 when it moves down, causing it to shake. Under the action of kinetic energy, it is more conducive to material shedding, and the chips in the gap are not easy to stick during the shaking process and fall as the isolation door panel 2 moves up and down.

[0035] The inner side spacing of the two guide groove members 4 is greater than the width of the isolation door panel 2 , and the spacing between the side of the guide groove member 4 and the door frame 1 is greater than the thickness of the isolation door panel 2 , and the isolation door panel 2 and the door frame 1 are set at a distance.

[0036] Not only can the guide groove members 4 be arranged at intervals to form a movement guide for the isolation door panel 2, but the intervals are also enlarged to reduce the problem of blockage, and space can be provided for the isolation door panel 2 to swing.

[0037] The driving mechanism includes a base 5 fixedly connected to the lower inner side of the door frame 1, and a corresponding hydraulic cylinder 6 is upright and fixedly installed on the base 5. The end of the piston rod of the hydraulic cylinder 6 is installed with a corresponding ear seat 8 through a transversely fixed connecting plate 7. The top of the isolation door panel 2 is fixed with an ear plate 9 that is compatible with the ear seat 8. By inserting a connecting rod connecting the ear plate 9 and the ear seat 8, the isolation door panel 2 can be swung back and forth and installed below the connecting plate 7.

[0038] Furthermore, while ensuring that the hydraulic cylinder 6 firmly supports and installs the isolation door panel 2, a hinged connection is formed by inserting a connecting rod connecting the ear plate 9 and the ear seat 8, so that the isolation door panel 2 can be swung back and forth.

[0039] The scraping mechanism includes a scraper plate 10 obliquely arranged on the lower front side of the counterweight block 3 . The outer side surface of the counterweight block 3 is arranged as an inwardly inclined surface, and the end of the scraper plate 10 abuts against the inclined surface.

[0040] The present invention is equipped with an inclined scraper plate 10, which is assisted by the up and down movement of the isolation door panel 2 and the resulting deflection, which is more conducive to the automatic removal of chips and effectively prevents chips from sticking to the isolation door panel 2 and affecting the movement of the isolation door panel 2. Furthermore, the outer side surface of the counterweight block 3 is inclined, ensuring that the isolation door panel 2 is vertically arranged during the ascent, and the inclined surface acts as a guide during the descent, allowing the isolation door panel 2 to deform and tilt, which is more conducive to improving the scraping effect.

[0041] The scraper 10 is made of rubber or plastic.

[0042] The isolation door panel 2 is a hollow and lightweight door body.

[0043] A corresponding sensor is provided on the inner side of the top of the door frame 1 , and the sensor senses the movement of the main shaft and transmits a signal, and the drive mechanism is actuated to drive the isolation door panel 2 to move downward.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
