Description

Technical Field

[0001] This invention relates to the field of straight-line tool magazine technology, and more particularly to a sealing mechanism for a straight-line tool magazine. Background Technology

[0002] The tool magazine primarily provides tool storage locations and, under program control, correctly selects and positions tools for exchange. Its automatic tool changer and ability to store multiple tools revolutionize traditional, human-intensive production methods. Through computer program control, various machining requirements can be met, such as milling, drilling, boring, and tapping, significantly shortening machining time and reducing production costs—this is the most significant characteristic of a tool magazine system.

[0003] The existing linear tool magazines have basically the same structure and principle. They all use a transmission device to push the tool turret (including the tool holder) to the bottom of the machine spindle. The up and down movement of the machine spindle is used to put the tool into the tool turret and take it out of the tool turret. At the same time, some waterproof and chip-proof devices are installed around the tool turret. However, for the sake of convenient tool changing, many linear tool magazines are mainly distributed in the cross frame or edge near the machining area. The enclosure structure is simple, and the tool surface is easily contaminated with droplets, debris and other impurities. It is necessary to clean the dirt on the tool holder and tool shank regularly with a clean cloth or brush.

[0004] In view of this, the present invention provides a straight-line tool magazine sealing mechanism to solve the technical problems existing in the prior art. Summary of the Invention

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] Reference Figures 1-10 The straight-flow tool magazine sealing mechanism includes a tool magazine housing 1. Two end caps 3 are installed at the front end of the tool magazine housing 1, and a rear end plate 15 is installed at the rear end of the tool magazine housing 1. A camera for inspecting the tool surface is installed at the top inside the tool magazine housing 1. Pushing mechanisms 7 are installed at both ends inside the tool magazine housing 1, and a tool compartment 2 is installed between the two pushing mechanisms 7. A conversion mechanism is rotatably installed inside the tool compartment 2, and two sets of clamping mechanisms 4 are installed on the outside of the conversion mechanism. An arc-shaped movable cover mechanism 14 is also installed between the two pushing mechanisms 7. Multiple drive cylinders 9 are installed on the outer side of the rear end plate 15, and a tool cleaning mechanism 10 is installed at the front end of the drive cylinders 9. A blowing mechanism 11 is installed on the top of the tool cleaning mechanism 10. A guide frame 13 is installed on the inner side of the rear end plate 15, and a slot is provided at the bottom of the guide frame 13 to slide with the tool cleaning mechanism 10 and the blowing mechanism 11. A recycling mechanism 8 that cooperates with the tool cleaning mechanism 10 is installed at the bottom of the tool magazine housing 1.

[0021] As a further embodiment of the present invention, the conversion mechanism includes a rotary motor 6 fixedly mounted on the propulsion mechanism 7 and a conversion shaft rotatably mounted inside the tool magazine 2. The output shaft of the rotary motor 6 is connected to the rotary shaft for transmission. A cylindrical conversion platform 5 is fixedly mounted on the outside of the rotary shaft. Two sets of clamping mechanisms 4 are symmetrically distributed on the outside of the conversion platform 5. In the present invention, the clamping mechanism 4 for clamping the tool is installed on the outside of the conversion platform 5. When the conversion platform 5 moves 90º, the tool changes position once, so that the tool can be rotated and adjusted in the horizontal and vertical directions, and the tool can be quickly selected and positioned.

[0022] As a further embodiment of the present invention, the clamping mechanism 4 includes a clamping base and two movable clamps hinged to the clamping base. The front ends of the two movable clamps are C-shaped, and the rear ends of the two movable clamps are connected by a spring. In the present invention, the front ends of the two movable clamps of the clamping mechanism 4 are C-shaped. The middle part of the tool shank is squeezed into the opening of the movable clamp. Under the action of the spring, the two movable clamps are embedded in the groove of the tool shank, completing the quick clamping and fixing of the tool. The tool is then removed to the machine head to fix the tool. The tool magazine 2 moves backward, which can remove the tool from the clamping mechanism 4 and improve the tool changing efficiency.

[0023] As a further embodiment of the present invention, the tool magazine 2 has a cylindrical structure, and a tool changing port 12 is provided on the upper front side of the tool magazine 2. A cleaning port that cooperates with the tool cleaning mechanism 10 is provided on the lower rear side of the tool magazine 2. In the present invention, the tool rotates and changes position inside the tool magazine 2. When the blade edge of the tool is horizontally positioned inside the cleaning port, the tool cleaning mechanism 10 can be inserted to clean the blade edge. When the tool handle is vertically distributed in the tool changing port 12, it is convenient for the machine head to be inserted to perform the tool changing action.

[0024] The machine tool is equipped with two sets of clamping mechanisms 4 for fixing tools. Both clamping mechanisms 4 can be driven to rotate by the conversion mechanism. After the tool change is completed, the movable cover mechanism 14 rotates forward to close the tool changing port 12 of the tool magazine 2. The tool magazine 2 is then pushed back into the tool magazine housing 1 by the push mechanism 7, so that the tool magazine is away from the working area of ​​the machine tool and avoids the tool magazine from being contaminated by cutting fluid droplets and debris. Afterward, the conversion mechanism drives the clamping mechanism 4 and the tool to rotate. The clamping mechanism 4 is in a vertical position and the tool is in a horizontal position. The tool shank at the lower end is set with the tool shank facing outward and the cutting edge facing inward. When there are stains on the surface of the newly replaced tool, the corresponding tool cleaning mechanism 10 moves forward and puts the cutting edge of the tool on the front end of the tool cleaning mechanism 10. The tool surface is effectively cleaned in conjunction with the blowing mechanism 11 to prevent stains from contaminating the tool and the tool magazine, enhance the protection and cleaning effect of the tool, and improve the machining efficiency of the machine tool.

[0025] As a further embodiment of the present invention, the propulsion mechanism 7 includes a limiting guide rail 71 located at one end inside the tool magazine housing 1, and a propulsion block 74 slidably installed inside the limiting guide rail 71. A threaded screw 73 is slidably installed inside the limiting guide rail 71, and a propulsion motor 72 that drives the threaded screw 73 to rotate is installed at the end of the limiting guide rail 71. The propulsion block 74 is threadedly connected to the threaded screw 73, and a U-shaped groove 75 adapted to the movable cover plate 14 mechanism is provided at the front end of the propulsion block 74. In the present invention, the tool magazine 2 and the movable cover mechanism 14 move horizontally in the tool magazine housing 1 through the action of the propulsion block 74. After the tool change is completed, the tool magazine 2 is quickly retracted to avoid contamination by debris and droplets.

[0026] As a further embodiment of the present invention, the movable cover mechanism 14 includes two gear rings 145 that rotate around a conversion axis, and an arc-shaped movable cover 141 installed between the two gear rings 145. The inner side of the arc-shaped movable cover 141 is provided with a limiting protrusion 142 that cooperates with the tool magazine 2. The movable cover mechanism 14 also includes a drive motor 144 installed on the propulsion mechanism 7. The output shaft end of the drive motor 144 is equipped with a transmission worm gear 143 that meshes with the gear rings 145. In the present invention, the arc-shaped movable cover 141 rotates coaxially around the outside of the tool magazine 2 under the drive of the drive motor 144 and the transmission worm gear 143 through the limiting effect of the gear rings 145, thereby completing the closing and opening operation of the tool changing port 12 of the tool magazine 2. The arc-shaped structure effectively prevents debris and other objects from staying on the outer surface of the movable cover mechanism 14, improving the protection effect of the tool magazine.

[0027] As a further embodiment of the present invention, the knife cleaning mechanism 10 includes an F-shaped cleaning seat 101, with a C-shaped fixing groove 104 at the front end of the cleaning seat 101, a brushing assembly 102 installed in the middle of the cleaning seat 101, and a slag discharge groove 103 connected to the recycling mechanism 8 at the bottom of the cleaning seat 101. In the present invention, the knife cleaning mechanism 10 moves forward under the push of the driving cylinder 9, and the blade edge of the knife is inserted into the brushing assembly 102. Through the cooperation of the brushing assembly 102 and the blowing mechanism 11, the cleaning operation of the dirt on the blade edge is quickly completed. During the forward movement of the knife cleaning mechanism 10, the bottom end of the clamping mechanism 4 is embedded in the C-shaped fixing groove 104, which effectively constrains the clamping mechanism 4, prevents the knife from falling off during the cleaning process, and improves the stability of knife cleaning.

[0028] As a further embodiment of the present invention, the scrubbing assembly 102 includes a scrubbing motor 1021 mounted on the cleaning seat 101 and a circular sleeve 1022 mounted on the output shaft end of the scrubbing motor 1021. The end of the circular sleeve 1022 is equipped with a spirally distributed elastic brush 1023. In the present invention, the blade edge is inserted into the spirally distributed elastic brush 1023. When the elastic brush 1023 rotates, it can scrub the blade edge. At the same time, the spiral bristles push debris and other debris toward the end of the circular sleeve 1022, which, together with the blowing mechanism 11, improves the cleaning efficiency of the blade edge stains.

[0029] As a further embodiment of the present invention, the purging mechanism 11 includes an air distribution pipe 114 mounted on the rear end plate 15 and a solenoid valve 112 mounted on the cleaning seat 101. An air distribution pipe 111 is installed between the solenoid valve 112 and the air distribution pipe 114. A J-shaped blowpipe 113 is installed at the outlet of the solenoid valve 112. In the present invention, when the tool cleaning mechanism 10 performs the cleaning action, the J-shaped blowpipe 113 sprays compressed air from top to bottom, and the nozzle is tilted downward. When the tool cleaning mechanism 10 moves back and forth on the outside of the blade, it quickly blows away the dirt on the blade edge and blows the dirt into the recycling mechanism 8, preventing the dirt from entering the tool compartment 2.

[0030] As a further embodiment of the present invention, the recycling mechanism 8 includes a filter 81 installed at the bottom of the tool magazine housing 1 and an isolation plate 83 installed on the upper end of the filter 81. The top of the isolation plate 83 is provided with a plurality of collection slots 82 that cooperate with the slag discharge slot 103. In the present invention, compressed air blows dirt from the collection slots 82 into the filter 81, and the filter 81 filters and intercepts debris and droplets in the exhaust gas, and recycles the debris.

[0031] When in use, the clamping mechanism 4 is horizontally distributed inside the tool magazine 2, with the tools arranged vertically and the tool holders on the outer side facing upwards. When a tool change is needed, the pushing mechanism 7 drives the clamping mechanism 4 to move horizontally to the front end of the tool magazine housing 1. Then, the movable cover mechanism 14 rotates backward to open the tool changing port 12 of the tool magazine 2. After the tool change is completed, the movable cover mechanism 14 rotates forward to close the tool changing port 12 of the tool magazine 2, and the pushing mechanism 7 pushes the tool magazine 2 back into the tool magazine housing 1, keeping the tool magazine away from the machine tool's working area and preventing the tool magazine from being contaminated by cutting fluid droplets and debris. Afterwards, the conversion mechanism drives the clamping mechanism 4 and the tool to rotate. The clamping mechanism 4 is in a vertical state, and the tool is in a horizontal state, with the tool holders at the lower end facing outwards and the cutting edges facing inwards. When the surface of the newly replaced tool is dirty, the corresponding tool cleaning mechanism 10 moves forward to place the cutting edge of the tool on the front end of the tool cleaning mechanism 10, and works with the blowing mechanism 11 to effectively clean the tool surface.

[0032] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
