Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a high-performance turret-type precision CNC machine tool. Background Technology

[0002] CNC machine tools, as the "mother machines" of modern manufacturing, are key equipment reflecting a nation's level of industrial modernization. Among them, the turret CNC machine tool is a highly efficient sheet metal processing equipment. Its core feature is a rotatable "turret" with multiple mold stations mounted on the machine body. During processing, the computing system controls the automatic positioning of the sheet metal and the turret, causing the required molds to rotate rapidly to the stamping position, thereby punching various shapes of holes or performing shallow drawing on the sheet metal.

[0003] On existing turret-type CNC machine tools, multiple fixtures are typically used to hold sheet metal. However, these fixtures are currently mostly bolted directly to the crossbeam, resulting in insufficient flexibility in position adjustment and difficulty in quickly adapting to the processing needs of sheet metal of different sizes and shapes. Furthermore, when punching is required in the clamping area of ​​the sheet metal, the fixtures need to be disassembled and the clamping position of the sheet metal readjusted. This process is cumbersome and seriously affects processing efficiency and the continuity of automated production. Utility Model Content

[0004] The purpose of this invention is to provide a high-performance turret-type precision CNC machine tool, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A high-performance turret-type precision CNC machine tool includes a machining table. A turret-type punch is mounted on one side of the machining table surface, and a crossbeam is mounted on the other side. A movable seat is mounted inside the crossbeam via a linear module. Three sliders are slidably mounted on the surface of the movable seat along its length. A positioning plate is provided on the surface of the movable seat. The surface of the sliders has slots, and the positioning plate is located inside the slots. Multiple positioning holes are arrayed on the surface of the positioning plate along its length. Positioning rods are inserted into the sliders, and the positioning rods are adapted to the positioning holes. An L-shaped lower clamping plate is mounted on the surface of the sliders via a telescopic mechanism, and an upper clamping plate is mounted on the surface of the L-shaped lower clamping plate via a clamping mechanism.

[0007] Furthermore, the telescopic mechanism includes multiple guide posts mounted on the surface of the slider, the vertical plate of the L-shaped lower clamping plate is slidably mounted on the multiple guide posts via linear bearings, a first cylinder is mounted on the surface of the slider, and the end of the telescopic end of the first cylinder is connected to the surface of the vertical plate of the L-shaped lower clamping plate.

[0008] Furthermore, the clamping mechanism includes two fixed blocks installed on the surface of the horizontal plate of the L-shaped lower clamping plate, the upper clamping plate is hinged between the two fixed blocks, the surface of the vertical plate of the L-shaped lower clamping plate is hinged with a second cylinder, the end of the extension end of the second cylinder is fitted with a hinge block, and the end of the upper clamping plate is hinged between the inner walls of the two sides of the hinge block.

[0009] Furthermore, a U-shaped plate is installed on the top of the slider, and the positioning rod slides through the interior of the U-shaped plate. The outer surface of the positioning rod is provided with a shoulder, and a spring is sleeved on the outer surface of the positioning rod. The two ends of the spring abut against the shoulder and the U-shaped plate, respectively.

[0010] Furthermore, positioning blocks are provided on the surface of the L-shaped lower clamping plate.

[0011] Furthermore, a pull block is installed on the top of the positioning rod, and the surface of the pull block is provided with anti-slip stripes.

[0012] Furthermore, the bottom of the positioning rod is provided with a ball bearing, and the top of the positioning hole is formed with an introductory chamfer to facilitate the insertion of the positioning rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model uses the insertion and cooperation of positioning rod and positioning hole. The slider can be quickly fixed by simply sliding it horizontally to the appropriate position on the surface of the moving seat. This allows for flexible changes in the horizontal position of the L-shaped lower clamp and upper clamp, quickly adapting to the processing needs of plates of different sizes and shapes.

[0015] 2. This utility model uses a telescopic mechanism to drive the L-shaped lower clamping plate to extend and retract back and forth. During the processing, the upper clamping plate can first release its clamping effect on the plate, and then retract it backward. After the punching process is completed in the clamping area, it can be clamped forward again. This eliminates the need to interrupt the processing and manually adjust the position, ensuring processing efficiency and production continuity. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] A turret-type punch 101 is provided on one side of the surface of the processing table 1, and a crossbeam 102 is provided on the other side of the surface of the processing table 1. A movable seat 103 is installed inside the crossbeam 102 via a linear module. Three sliders 104 are slidably mounted on the surface of the movable seat 103 along its length. A positioning plate 107 is provided on the surface of the movable seat 103. A slot 108 is opened on the surface of the slider 104, and the positioning plate 107 is located inside the slot 108. Multiple positioning holes 109 are arranged in an array along the length of the surface of the positioning plate 107. A positioning rod 110 is inserted into the inside of the slider 104, and the positioning rod 110 is adapted to the positioning hole 109. An L-shaped lower clamping plate 105 is installed on the surface of the slider 104 via a telescopic mechanism 2, and an upper clamping plate 106 is installed on the surface of the L-shaped lower clamping plate 105 via a clamping mechanism 3.

[0026] When the position of the fixture needs to be adjusted according to the size and shape of the sheet metal, the positioning rod 110 can be pulled upward to remove its end from the positioning hole 109, thereby releasing the fixation of the slider 104. Then, slide it horizontally to the appropriate position and reinsert the positioning rod 110 into the corresponding positioning hole 109. This achieves the purpose of quick adjustment of the fixture position and quickly adapts to the processing needs of sheet metal of different sizes and shapes.

[0027] The edge of the sheet metal is placed on the surface of the L-shaped lower clamping plate 105. The clamping mechanism 3 drives the upper clamping plate 106 to flip downwards to form a clamping action. Then, the crossbeam 102 and the linear module can move the sheet metal in the X and Y axes to perform punching. The processing table 1, the turret punch 101, the crossbeam 102, and the linear module are all existing technologies, so they will not be described in detail here. During the processing, if the clamping part of the sheet metal needs to be punched, the telescopic mechanism 2 and the clamping mechanism 3 can be controlled by the program. First, the clamping mechanism 3 drives the upper clamping plate 106 to flip upwards to release the clamping of the sheet metal. The other two clamps continue to hold the sheet metal in place. Then, the telescopic mechanism 2 drives the L-shaped lower clamping plate 105 to retract inwards to make room. After the clamping area has been punched, it is clamped forward again. This eliminates the need to interrupt the processing and manually adjust the position, ensuring processing efficiency and production continuity.

[0028] A U-shaped plate 4 is mounted on the top of the slider 104. The positioning rod 110 slides through the interior of the U-shaped plate 4. A shoulder 401 is provided on the outer surface of the positioning rod 110, and a spring 402 is sleeved on the outer surface of the positioning rod 110. The two ends of the spring 402 abut against the shoulder 401 and the U-shaped plate 4, respectively. A pull block 111 is mounted on the top of the positioning rod 110, and the surface of the pull block 111 is provided with anti-slip stripes. A ball bearing 112 is provided at the bottom of the positioning rod 110, and the top of the positioning hole 109 has an induction chamfer to facilitate the insertion of the positioning rod 110.

[0029] Since the positioning hole 109 into which the positioning rod 110 is to be inserted is blocked, in order to improve the insertion efficiency, when the positioning rod 110 is pulled upward, it causes the shoulder 401 to compress the spring 402. After the slider 104 moves to the appropriate position, the positioning rod 110 is released. At this time, the compressed spring 402 releases its elastic force, pushing the positioning rod 110 downward. If the positioning rod 110 is aligned with the positioning hole 109 at this time, it is inserted. If it is not aligned, the bottom of the positioning rod 110 abuts against the surface of the positioning plate 107, and then the slider 104 slides back and forth to make fine adjustments to its position. When the positioning rod 110 is aligned, it can be automatically inserted under the elastic force of the spring 402, thus fixing its position. Furthermore, the bottom of the positioning rod 110 slides back and forth while abutting against the positioning plate 107, which will generate a certain amount of frictional resistance and wear. Therefore, by setting the ball bearing 112, the frictional resistance and wear can be greatly reduced, allowing for smoother sliding and improving service life. By importing the chamfer setting, the positioning rod 110 can be inserted more easily, and by setting the pull block 111, the positioning rod 110 can be pulled upward more easily.

[0030] Please see Figure 1 and Figure 2 The telescopic mechanism 2 includes multiple guide posts 201 mounted on the surface of the slider 104. The vertical plate of the L-shaped lower clamping plate 105 is slidably mounted on the multiple guide posts 201 via linear bearings. A first cylinder 202 is mounted on the surface of the slider 104. The end of the telescopic end of the first cylinder 202 is connected to the surface of the vertical plate of the L-shaped lower clamping plate 105.

[0031] Multiple guide posts 201 provide guidance for the L-shaped lower clamping plate 105. When the first cylinder 202 is started, its telescopic end can drive the L-shaped lower clamping plate 105 to slide horizontally back and forth. Therefore, it can make way when punching is required in the clamping area, avoiding the need to manually adjust the position by interrupting the processing.

[0032] Please see Figure 3 and Figure 5 The clamping mechanism 3 includes two fixing blocks 301 mounted on the surface of the horizontal plate of the L-shaped lower clamping plate 105. The upper clamping plate 106 is hinged between the two fixing blocks 301. A second cylinder 302 is hinged to the surface of the vertical plate of the L-shaped lower clamping plate 105. A hinge block 303 is mounted on the end of the telescopic end of the second cylinder 302, and the end of the upper clamping plate 106 is hinged between the inner walls of the two sides of the hinge block 303. A positioning block 1051 is provided on the surface of the horizontal plate of the L-shaped lower clamping plate 105.

[0033] When the second cylinder 302 pushes the hinge block 303 downward, the connecting rod causes the end of the upper clamping plate 106 to flip upward. At this time, the plate can be placed on the L-shaped lower clamping plate 105, and the positioning block 1051 is used to position the edge of the plate to ensure the accuracy of the plate clamping position. Then, the second cylinder 302 pulls the hinge block 303 upward, and under the action of the connecting rod, the end of the upper clamping plate 106 flips downward, cooperating with the L-shaped lower clamping plate 105 to clamp the plate.

[0034] The specific workflow and working principle of this device are as follows.

[0035] When adjusting the position of the fixture, first pull the positioning rod 110 upward so that its end is pulled out of the positioning hole 109. Then slide it horizontally to the appropriate position and then reinsert the positioning rod 110 into the corresponding positioning hole 109.

[0036] The edge of the sheet metal is placed on three L-shaped lower clamping plates 105. The second cylinder 302 pulls the hinge block 303, causing the upper clamping plate 106 to flip downwards for clamping. Then, the crossbeam 102 and the linear module move the sheet metal in the X and Y axes, and the turret punch 101 performs punching. During processing, if the clamped area of ​​the sheet metal needs to be processed, the programming program can control the second cylinder 302 to push the hinge block 303 downwards, causing the upper clamping plate 106 to open and release the clamp. Then, the first cylinder 202 drives the slider 104 to retract inwards to make room. After the punching of the clamped area is completed, the sheet metal is clamped again forward. This eliminates the need to interrupt processing and manually adjust the position, ensuring processing efficiency and production continuity.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
