Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of milling, and particularly relates to a double-station cooperative glass numerical control slot milling device. BACKGROUND

[0002] The double-station cooperative glass numerical control slot milling device is a high-efficiency solution developed by modern industry to improve the efficiency of large-scale glass finishing. The core design concept of this kind of device is to integrate two independent slot milling units on the same numerical control machine tool, so that the device can produce two products at the same time when completing one machining cycle, thereby greatly reducing the non-machining waiting time in the production process, significantly improving the utilization rate of the machine tool and the overall production efficiency, and being particularly suitable for industrial production scenarios that require multi-slot, multi-surface or batch slot milling of glass.

[0003] In the existing glass numerical control slot milling process, the high-speed rotating milling cutter generates strong radial annular airflow, which seriously interferes with the spraying path of the cooling liquid, causing it to be unable to stably and accurately cover the milling point. The scattering of the cooling liquid not only causes waste of resources and pollution of the environment, but more importantly, the contact area between the cutter and the glass cannot be effectively cooled and lubricated, thereby exacerbating cutter wear and easily inducing micro-cracks on the glass surface due to local high temperature, ultimately restricting the improvement of processing quality and the reduction of production cost.

[0048] The moving seat 201 is also provided with a cooling liquid delivery system 207, which comprises a plurality of branch pipelines 2072 arranged in an annular array, and it is to be noted that the branch pipelines 2072 are preferably made of stainless steel, so that the branch pipelines 2072 will not be bent and wound under the action of centrifugal force during the rotation of the milling cutter 206, and the lower end of each branch pipeline 2072 is provided with a spray head 2073, and the spray direction of each spray head 2073 corresponds to the starting end of a spiral flow guide groove 2033.

[0049] The rotating drive assembly 202 and the liquid collecting cover 203 are provided with a follow-up assembly 208, which allows the liquid collecting cover 203 to move outside the milling cutter 206.

[0050] Specifically, the liquid collecting cover 203 and the plurality of branch pipelines 2072 are driven to rotate at the same speed by the rotating drive assembly 202 during the rotation of the milling cutter 206, so as to wrap the cutter milling area by the liquid collecting cover 203, thereby avoiding the problem that the high-speed milling cutter 206 rotation generates radial annular airflow, which is easy to blow the cooling liquid off course, in addition, the spiral flow guide groove 2033 is opposite to the rotation direction of the cutter, and after the cooling liquid enters the spiral flow guide groove 2033, the cooling liquid makes circular motion along the spiral trajectory of the spiral flow guide groove 2033 under the inertia of the airflow driven by the milling cutter 206 and the constraint of the groove wall, forming a continuous liquid film close to the groove wall, the liquid film shrinks downward along the spiral flow guide groove 2033, gradually converges to the center, and finally accurately guides the milling end of the cutter.

[0051] Further, the follow-up assembly 208 comprises a sliding sleeve rod 2081 arranged in parallel on both sides of a fish eye bearing 2084, the inner side of the sliding sleeve rod 2081 is slidably connected with a sliding rod 2083, and the inside of the sliding sleeve rod 2081 is provided with a spring 2082 connected with the sliding sleeve rod 2081 and the sliding rod 2083 at the upper and lower ends respectively, which plays a role of resetting, so that the sliding rod 2083 can return to the initial position after moving in the sliding sleeve rod 2081;

[0052] The lower end of the sliding sleeve rod 2081 is fixedly connected with the fish eye bearing 2084, which can realize multi-angle rotation, thereby allowing the liquid collecting cover 203 to have a certain swinging space around the milling cutter 206, and the top of the liquid collecting cover 203 is provided with a top ring seat 2031, and each fish eye bearing 2084 is connected with the top ring seat 2031 through a fixed seat 2085;

[0053] The outer wall of the rotating shaft 2023 is fixedly connected with a deep groove ball bearing 2086, the outer wall of the deep groove ball bearing 2086 is fixedly provided with a connecting ring 2087, and the top of the sliding rod 2083 is fixedly connected to the bottom surface of the connecting ring 2087.

[0054] Specifically, when the milled glass is uneven, the flatness error of the glass surface can be compensated by the elastic deformation of the sliding sleeve rod 2081, the spring 2082 and the sliding rod 2083 when the liquid collecting cover 203 is close to the glass workpiece along with the milling cutter 206.

[0055] Further, the top of the moving seat 201 is provided with a transfer warehouse 205, and a liquid inlet pipe 2051 is arranged on the side wall of the transfer warehouse 205, which is used to be connected with an external cooling liquid delivery pump, so as to continuously supply cooling liquid.

[0056] Further, the side wall of the transfer warehouse 205 is also provided with a square liquid outlet hole 2052, which is higher than the installation position of the liquid inlet pipe 2051, and the square liquid outlet hole 2052 is in through connection with the upper end of the main liquid delivery pipe 2074, so that the cooling liquid transferred in the transfer warehouse 205 flows into the main liquid delivery pipe 2074 from the square liquid outlet hole 2052, and sealing treatment needs to be done between the outer wall of the main liquid delivery pipe 2074 and the transfer warehouse 205 to avoid the leakage of cooling liquid and drop to the surrounding, causing waste. An O-shaped sealing ring can be added at the connection part of the main liquid delivery pipe 2074 and the square liquid outlet hole 2052.

[0057] Further, the rotating drive assembly 202 comprises a rotating shaft 2023 rotatably arranged on the moving seat 201, and a rotating drive motor is also arranged on the moving seat 201, and a main gear 2021 is arranged on the output end of the rotating drive motor, and a secondary gear 2022 is in meshing connection with the main gear 2021, and the secondary gear 2022 is fixedly connected to the rotating shaft 2023.

[0058] The lower end of the rotating shaft 2023 is fixedly connected with a hollow sleeve 2024, which is preferably made of copper alloy material and has super hardness, which is used to provide space for the installation of the rotating joint 2071, and the lower end of the hollow sleeve 2024 is fixedly connected with the milling cutter 206.

[0059] Further, the cooling liquid delivery system 207 further comprises a main liquid delivery pipe 2074, which is penetrated through the rotating shaft 2023 from the inside of the hollow sleeve 2024 and extends upward.

[0060] The bottom end of the main liquid delivery pipe 2074 is provided with a rotating joint 2071, which is located in the inside of the hollow sleeve 2024. It should be noted that the rotating joint 2071 is a rotating joint with upper and lower parts rotating with each other, which is used to connect the main liquid delivery pipe 2074 and the plurality of branch pipes 2072 together.

[0061] Specifically, since the milling cutter 206 drives the multiple branch pipes 2072 to rotate, by arranging the rotary joint 2071 between the main liquid conveying pipe 2074 and the branch pipes 2072, the arrangement of the cooling pipes does not affect each other while the cutter rotates, and the space utilization is saved.

[0062] Further, the flow control assembly 209 is arranged between the transfer bin 205 and the follower assembly 208, the flow control assembly 209 comprises a rubber plug 2098 which is slidingly arranged in the interior of the transfer bin 205, the rubber plug 2098 is tightly sealed with the inner wall of the transfer bin 205, and the rubber plug 2098 can block the cooling liquid from entering the upper area of the transfer bin 205.

[0064] The outer wall of the sliding sleeve rod 2081 is fixedly provided with a fixed disc 2091 which is located below the heightening rod 2093.

[0065] Specifically, in the process of milling and grooving the surface of the glass by using the milling cutter 206, the depth of the milling cutter 206 inserted into the glass gradually increases, but the liquid collecting cover 203 is still located on the surface of the glass, so that the liquid collecting cover 203 is subjected to an upward pushing force in the opposite direction of the milling cutter 206, and then the sliding sleeve rod 2081 is pushed upward relative to the sliding rod 2083 through the transmission of the fixed seat 2085 and the fish-eye bearing 2084, and the fixed disc 2091 is moved upward by the sliding sleeve rod 2081. The fixed disc 2091 lifts the heightening rod 2093, that is, the heightening rod 2093 slides upward relative to the limiting sleeve rod 2092, and the heightening rod 2093 drives the rubber plug 2098 to slide upward in the interior of the transfer bin 205 through the lifting frame 2096 and the connecting rod 2097, at this time, the part of the square liquid outlet hole 2052 blocked by the rubber plug 2098 gradually becomes smaller, that is, the cooling liquid flow channel becomes larger, and then the amount of the cooling liquid entering the interior of the main liquid conveying pipe 2074 per unit time becomes larger, and the amount of the cooling liquid sprayed to the milling cutter 206 and the surrounding area becomes larger, so that the amount of the cooling liquid sprayed can be adaptively controlled according to the depth of the milling cutter 206 inserted into the glass, and the cooling liquid can be reasonably distributed.

[0066] Further, the lower end of each of the heightening rods 2093 is provided with a ball seat 2094, a rolling ball 2095 is arranged in the cavity of the ball seat 2094 and is in contact with the upper surface of the fixing disc 2091, so that the fixing disc 2091 can rotate along with the sliding sleeve rod 2081, the rolling ball 2095 is in contact with the fixing disc 2091, and the abrasion caused by the direct contact between the fixing disc 2091 and the heightening rod 2093 is avoided.

[0067] Further, the inner radius of the top ring seat 2031 is greater than the radius of the outer wall of the rotating shaft 2023, so that the top ring seat 2031 is not stuck by the rotating shaft 2023 during the swinging of the liquid collecting cover 203.

[0068] Further, the bottom of the liquid collecting cover 203 is further provided with a flexible lip 2032, preferably made of rubber, so that the bottom of the liquid collecting cover 203 can avoid scratching the glass.
