Description

Technical Field

[0001] The present invention relates to the technical field of engraving machines, and particularly to an engraving machine capable of replacing cutters of different models. Background Art

[0002] An engraving machine is a type of numerically controlled machine tool. A metal laser engraving machine can perform non-contact cutting and punching on metal or non-metal plates and pipes, and is particularly suitable for laser cutting and processing of materials such as stainless steel plates, iron plates, silicon wafers, ceramic chips, titanium alloys, epoxy, A3 steel, and diamond. This equipment runs stably and reliably, has good processing quality, high efficiency, and is simple to operate and convenient to maintain.

[0003] During the use of an engraving machine, the cutter may break, and a part of the broken cutter will remain in the fixture. Therefore, some tools are required to take out the broken cutter. Summary of the Invention

[0004] The purpose of the present invention is to provide an engraving machine capable of replacing cutters of different models in order to solve the above problems.

[0005] In order to achieve the above purpose, an engraving machine capable of replacing cutters of different models adopts the following technical solutions: It includes the body of the engraving machine, a workbench, a cutter, and a clamping seat for clamping the cutter. An installation seat is provided at the upper end of the clamping seat. The outer wall of the installation seat is threadedly connected with a limiting cylinder. A first receiving cavity is opened at the middle position of the installation seat, and a jacking component is arranged in the first receiving cavity.

[0006] The jacking component includes a first spring. A baffle is provided at the upper end of the first spring. A flared opening is opened at the upper end of the first receiving cavity. A plurality of groups of first sliding grooves are evenly opened on the outer wall of the flared opening. A clamping block for clamping the cutter is arranged in each group of first sliding grooves. A convex platform for cooperating with the first sliding groove is arranged on the outer wall of the clamping block. A separating component is arranged inside the clamping block, and a second receiving cavity for cooperating with the separating component is opened in the clamping block.

[0007] Further, the separating component includes a sliding rod. The sliding rod is connected to the second receiving cavity, passes through the second receiving cavity and extends to the outside of the clamping block. A second spring is arranged at one end of the sliding rod located in the second receiving cavity. A second sliding groove for cooperating with the sliding rod is opened in the limiting cylinder. The second sliding groove is annularly arranged. The cross-sections of the convex platform and the first sliding groove are both trapezoidal.

[0008] Further, the sliding rod is inclined, and the sliding rod is parallel to the inclined surface of the clamping block.

[0009] Furthermore, the cross-section of the clamping block is trapezoidal. The upper end of the limiting cylinder is a frustum-shaped cavity for cooperating with the clamping block. A frustum-shaped rotating cylinder is rotatably arranged inside the frustum-shaped cavity, and the lower end of the limiting cylinder is a cylinder.

[0010] Furthermore, an arc-shaped surface for convenient clamping is arranged at a position of the clamping block close to the center.

[0011] Furthermore, fixing blocks are arranged at the bottom of the first storage cavity and the lower end surface of the baffle. Through holes for cooperating with the first spring are opened in the fixing blocks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when the limiting cylinder is screwed, the cavity between the limiting cylinder and the mounting seat gradually becomes larger. The clamping block moves toward the side away from the tool under the cooperation of the ejecting assembly and the separating assembly, so as to facilitate the staff to replace the tool. At the same time, when the tool breaks, since the clamping blocks all move toward the side away from the tool, the limiting cylinder is rotated downward to make the broken tool inside the limiting cylinder slide out, so as to facilitate the staff to take out the broken tool.

[0023] Refer to Figure 1-6 , a carving machine capable of replacing tools of different models, including the body of the carving machine, a workbench, a tool 2, and a clamping seat 1 for clamping the tool 2. An upper end of the clamping seat 1 is provided with a mounting seat 101. An outer wall of the mounting seat 101 is threadedly connected with a limiting cylinder 3. A middle position of the mounting seat 101 is provided with a first storage cavity 1011. An ejecting assembly 6 is arranged in the first storage cavity 1011.

[0024] The ejecting assembly 6 includes a first spring 601. An upper end of the first spring 601 is provided with a baffle 602. An upper end of the first storage cavity 1011 is provided with a flared opening. A plurality of groups of first chutes 1012 are uniformly arranged on an outer wall of the flared opening. Each group of first chutes 1012 is provided with a clamping block 4 for clamping the tool 2. An outer wall of the clamping block 4 is provided with a boss 401 for cooperating with the first chute 1012. A separating assembly 8 is arranged inside the clamping block 4. The clamping block 4 is provided with a second storage cavity for cooperating with the separating assembly 8.

[0025] The separating assembly 8 includes a slide bar 801. The slide bar 801 is connected to the second storage cavity. The slide bar 801 penetrates through the second storage cavity and extends to the outside of the clamping block 4. A second spring 802 is arranged at one end of the slide bar 801 located in the second storage cavity. The limiting cylinder 3 is provided with a second chute for cooperating with the slide bar 801. The second chute is annularly arranged. Cross sections of the boss 401 and the first chute 1012 are both trapezoidal.

[0026] The slide bar 801 is obliquely arranged, and the slide bar 801 is parallel to an inclined surface of the clamping block 4.

[0027] In practical applications, turn the limiting cylinder 3, so that the cavity between the limiting cylinder 3 and the mounting seat 101 gradually becomes larger. In the cooperation of the ejecting assembly 6 and the separating assembly 8, the clamping block 4 moves to the side away from the tool 2, thus facilitating the staff to replace the tool 2. At the same time, when the tool 2 breaks, since the clamping blocks 4 all move to the side away from the tool 2, turn the limiting cylinder 3 downward, so that the broken tool 2 inside the limiting cylinder 3 slides out, thus facilitating the staff to take out the broken tool 2;

[0028] In the ejecting assembly 6, the first spring 601 pushes the baffle 602 to reset upward, the baffle 602 pushes the clamping block 4 to reset upward, and the boss 401 on the outer wall of the clamping block 4 slides along the first chute 1012, so that the clamping block 4 moves to the side away from the tool 2; at the same time, since the cross-sections of the boss 401 and the first chute 1012 are both trapezoidal, when the limiting cylinder 3 rotates, the clamping block 4 will not tilt;

[0029] Since the slide bar 801 is parallel to the inclined surface of the clamping block 4, in the separating assembly 8, the second spring 802 pushes the slide bar 801 to move outside the clamping block 4, so that the clamping block 4 moves to the side away from the tool 2.

[0030] Furthermore, the cross-section of the clamping block 4 is trapezoidal, the upper end of the limiting cylinder 3 is a frustum-shaped cavity for cooperating with the clamping block 4, and a frustum-shaped rotating cylinder 301 is rotatably arranged inside the frustum-shaped cavity. The lower end of the limiting cylinder 3 is a cylinder; in practical applications, since the cross-section of the clamping block 4 is trapezoidal, when the limiting cylinder 3 is turned, the limiting cylinder 3 presses the clamping block 4, and the clamping block 4 squeezes toward the middle position, and the clamping block 4 clamps the tool 2.

[0031] Furthermore, an arc surface convenient for clamping is arranged at a position of the clamping block 4 close to the center.

[0032] Furthermore, fixing blocks 7 are arranged at the bottom of the first storage cavity 1011 and the lower end surface of the baffle 602, and through holes for cooperating with the first spring 601 are opened in the fixing blocks 7; in practical applications, the upper and lower ends of the first spring 601 respectively pass through the through holes to lock the first spring 601 and the baffle 602.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
