Description

Technical Field

[0001] This utility model relates to the field of milling machine tool technology, and in particular to a clamping table for an end milling machine tool. Background Technology

[0002] A milling machine tool is a machine tool that uses a rotating cutting tool to cut workpieces. It is mainly used for machining planes, grooves, gears, threads, and complex three-dimensional contours.

[0003] Existing technologies, such as the utility model patent with publication number CN201711574U, fall under the technical field of CNC machine tools, specifically a milling CNC machine tool. This machine tool includes a worktable with two opposing milling heads positioned on it. Two clamps are located between the two milling heads. A material support device is positioned in the middle of the worktable. This device includes a hydraulic cylinder and a support plate mounted on the cylinder. The upper surface of the support plate forms an arc shape that conforms to the workpiece. The advantages of this utility model are that, compared to previous machine tools, it adds a material support device that eliminates the need for manual disassembly of heavy workpieces. The machine tool can be directly controlled, and after the heavy workpiece is processed, the material support device can directly lift the workpiece and remove it from the worktable. The operation is quick, the structure is simple, and it requires minimal manpower.

[0004] Regarding the above-mentioned issues, the following technical defects were found: During the operation of milling machine tools, it is difficult to clamp workpieces of different sizes, which can easily cause the workpieces to shift during processing, resulting in a decrease in the machining accuracy of the workpieces. This necessitates frequent manual alignment of the workpieces, reducing the production efficiency of the milling machine tools. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies.

[0006] To solve the above technical problems, this utility model provides a clamping table for an end milling machine tool, comprising: a frame, the frame being L-shaped, a lifting mechanism mounted on the long arm end of the frame, a machining head mounted on one side of the lifting mechanism, a transmission mechanism mounted on the short arm end of the frame, a worktable fixedly connected to the upper surface of the transmission mechanism, a clamping device provided on the side of the worktable, the clamping device comprising a plurality of welding plates, one side of each welding plate being fixedly connected to one side of the worktable, a lead screw rotatably connected to the adjacent sides of every two welding plates, a pulley fixedly connected to the arc surface of the lead screw, a belt drivingly connected to the arc surface of the pulley, and threads with opposite directions formed on the arc surfaces of both ends of the lead screw. The screw has two clamping plates threaded to its arc-shaped surface. The clamping plates have a U-shaped cross-section. Several clamping rods slide through one side of the clamping plates. Springs are fitted onto the arc-shaped surfaces of the clamping rods. The two ends of the springs are fixedly connected to one end of the clamping rod and one side of the clamping plate, respectively. The arc-shaped surfaces of the clamping rods have slots. Several limiting holes are formed on the upper surface of the clamping plates. The size of the limiting holes corresponds to the position of the slots. An mounting plate is fixedly connected to the upper surface of the clamping plate. A screw is threaded to the upper surface of the mounting plate. A moving plate is fixedly connected to the lower end of the screw. A positioning post is fixedly connected to the lower surface of the moving plate. The size of the positioning post matches the size of the limiting holes.

[0007] The effect achieved by the above components is that the clamping device set on the side of the worktable can clamp the workpiece to be processed, which helps to fix the position of the workpiece, avoid dimensional deviations caused by vibration or displacement during processing, and improve processing accuracy.

[0008] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to the lower end of the positioning post.

[0009] The effect achieved by the above components is to increase the friction between the lower end of the positioning post and the inner wall of the slot by using the anti-slip pad, thereby preventing the clamping rod from shifting during the clamping of the workpiece.

[0010] Preferably, two sliding rods are slidably provided on the upper surface of the mounting plate, and the lower ends of the sliding rods are fixedly connected to the upper surface of the movable plate.

[0011] The effect achieved by the above components is that the sliding rod limits the movement of the moving plate, thus preventing the moving plate from rotating when the screw is used to move the moving plate.

[0012] Preferably, a motor is fixedly connected to one side of the workbench, and the output end of the motor is fixedly connected to one of the lead screws.

[0013] The effect achieved by the above components is that the rotation of the motor enables the lead screw to rotate rapidly, avoiding the tediousness of manual operation.

[0014] Preferably, the upper surface of the workbench is provided with an extension device, the extension device including a movable groove, the movable groove being opened on the upper surface of the workbench, a gear being rotatably connected to the inner wall of the movable groove, two racks being slidably connected to the inner wall of the movable groove, the gear meshing with the racks, and an extension plate being fixedly connected to the upper surface of the racks, the extension plate having an "L" shaped cross-section.

[0015] The effect achieved by the above components is that the extension device set on the surface of the worktable facilitates the clamping of larger workpieces, thereby improving the safety and stability of workpiece processing.

[0016] Preferably, an electric actuator is fixedly connected to the inner wall of the movable slot, and the output end of the electric actuator is adapted to the lower surface of one of the expansion plates.

[0017] The effect achieved by the above components is that the extension plate is driven by the electric actuator, which facilitates the precise movement of the extension plate and makes it easy to adapt the extension plate to workpieces of different sizes.

[0018] Preferably, the inner wall of the movable groove is provided with a sliding groove, and a roller is rotatably connected inside the sliding groove, with one side of the roller rotatably connected to the extension plate.

[0019] The effect achieved by the above components is that they facilitate the movement of the extension plate by rotating the rollers inside the slide groove, thus avoiding friction between the extension plate and the moving groove during prolonged movement, which could cause the extension plate to jam.

[0020] Compared with related technologies, the end milling machine tool clamping table provided by this utility model has the following advantages:

[0021] Beneficial effects:

[0022] This utility model provides a clamping table for an end milling machine tool. By operating the clamping device, it is possible to clamp workpieces of different sizes. With the help of a motor rotation, two lead screws are driven to rotate simultaneously through pulleys and belts. This causes the clamping plate to drive the clamping rod to clamp the workpieces of different sizes using springs. Then, by rotating the screw, the moving plate moves downward, and the positioning post restricts the clamping rod to prevent it from moving. This helps to improve the machining accuracy of the workpiece and avoid dimensional deviations caused by vibration or displacement during machining.

[0023] By operating the extension device, it is possible to conveniently place large workpieces onto the surface of the worktable. One of the extension plates is moved by an electric actuator, and with the help of gears and racks, both extension plates are unfolded simultaneously. This makes it easier to keep large workpieces stable during processing, which helps to ensure the safety and stability of workpiece processing. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1The present invention provides a clamping table for an end milling machine tool, comprising: a frame 1, the frame 1 being L-shaped, a lifting mechanism 2 installed at the long arm end of the frame 1, a processing head 3 installed on one side of the lifting mechanism 2, a transmission mechanism 4 installed at the short arm end of the frame 1, a worktable 5 fixedly connected to the upper surface of the transmission mechanism 4, a clamping device 6 provided on the side of the worktable 5, and an extension device 7 provided on the upper surface of the worktable 5.

[0033] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The clamping device 6 includes several welding plates 601. One side of each welding plate 601 is fixedly connected to one side of the worktable 5. A lead screw 602 is rotatably connected to the side of every two welding plates 601 that are close to each other. A pulley 603 is fixedly connected to the arc surface of the lead screw 602. A belt 604 is driven through the arc surface of the pulley 603. The arc surfaces at both ends of the lead screw 602 are threaded with opposite threads. Two clamping plates 605 are threaded to the arc surface of the lead screw 602. The cross-section of the clamping plate 605 is U-shaped. Several clamping rods 606 slide through one side of the clamping plate 605. Springs 606 are sleeved on the arc surface of the clamping rods 606. 7. The two ends of the spring 607 are fixedly connected to one end of the clamping rod 606 and one side of the clamping plate 605, respectively. The arc surface of the clamping rod 606 has a slot 608. The upper surface of the clamping plate 605 has several limiting holes 614, the size of which corresponds to the position of the slot 608. The upper surface of the clamping plate 605 is fixedly connected to the mounting plate 609. The upper surface of the mounting plate 609 is threadedly connected to the screw 611. The lower end of the screw 611 is fixedly connected to the moving plate 612. The lower surface of the moving plate 612 is fixedly connected to the positioning post 613, the size of which matches the size of the limiting hole 614. The clamping device 6 provided on the side of the worktable 5 is used to clamp the workpiece to be processed, which helps to fix the position of the workpiece, avoid dimensional deviations caused by vibration or displacement during processing, and improve processing accuracy. The lower end of the positioning post 613 is fixedly connected to the anti-slip pad 610, which is a rubber pad. The anti-slip pad 610 increases the friction between the lower end of the positioning post 613 and the inner wall of the slot 608, preventing the clamping rod 606 from shifting during workpiece clamping. Two sliding rods 616 are slidably mounted on the upper surface of the mounting plate 609, with the lower ends of the sliding rods 616 fixedly connected to the upper surface of the moving plate 612. The limiting effect of the sliding rods 616 on the moving plate 612 prevents rotation of the moving plate 612 when moved by the screw 611. A motor 615 is fixedly connected to one side of the worktable 5, and the output end of the motor 615 is fixedly connected to one of the lead screws 602. The rotation of the motor 615 allows for rapid rotation of the lead screw 602, avoiding the tediousness of manual operation.

[0034] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The expansion device 7 includes a movable groove 71, which is located on the upper surface of the worktable 5. A gear 72 is rotatably connected to the inner wall of the movable groove 71, and two racks 73 are slidably connected to the inner wall of the movable groove 71. The gear 72 meshes with the racks 73, and an expansion plate 74 with an "L"-shaped cross-section is fixedly connected to the upper surface of the racks 73. The expansion device 7, located on the upper surface of the worktable 5, facilitates the clamping of larger workpieces, improving the safety and stability of workpiece processing. An electric actuator 75 is fixedly connected to the inner wall of the movable groove 71, and the output end of the electric actuator 75 is adapted to the lower surface of one of the expansion plates 74. The electric actuator 75 drives the expansion plate 74, enabling precise movement of the expansion plate 74 and allowing it to adapt to workpieces of different sizes. A sliding groove 76 is provided on the inner wall of the movable groove 71, and a roller 77 is rotatably connected inside the sliding groove 76. One side of the roller 77 is rotatably connected to the expansion plate 74. It is beneficial to use the rotation of the roller 77 inside the slide groove 76 to move the extension plate 74, and avoid the extension plate 74 from moving for a long time and causing friction with the moving groove 71, which could cause the extension plate 74 to get stuck.

[0035] The working principle of the end milling machine tool clamping table provided by this utility model is as follows: When a workpiece needs to be milled, in order to ensure that the workpiece does not fail to process due to displacement during the processing, a clamping device 6 is used to clamp workpieces of different sizes. First, the workpiece is placed on the upper surface of the worktable 5, and then the motor 615 is started. The rotation of the motor 615 drives one of the lead screws 602 fixedly connected to the motor 615 to rotate. The rotation of the lead screw 602 drives one of the pulleys 603 to rotate. The rotation of the pulley 603 drives the belt 604 to drive the other pulley 603 to rotate, thereby causing both lead screws 602 to rotate simultaneously. When the screw 602 rotates, it drives the clamping plate 605 to move. When the clamping plate 605 moves, it drives the clamping rod 606 to clamp the workpiece. Due to the elasticity of the spring 607, the clamping rod 606 will clamp workpieces of different sizes. Then, the screw 611 is rotated to drive the moving plate 612 to move downward, so that the positioning post 613 fixes the clamping rod 606 to prevent the workpiece from moving during the processing. After the workpiece is processed, the screw 611 is rotated again to make the positioning post 613 release the clamping rod 606. Then, the motor 615 is used to rotate the screw 611 to release the clamping plate 605. Finally, the motor 615 is turned off and the workpiece is taken out.

[0036] When the workpiece size is too large, and the extension device 7 is required to ensure processing stability and accuracy, the electric push rod 75 is activated first. The electric push rod 75 pushes one of the extension plates 74, which moves along the slide groove 76 with the help of the roller 77. One extension plate 74 drives one of the racks 73 to move. The movement of one rack 73 drives the gear 72 to rotate. The rotation of the gear 72 drives the other rack 73 to move, so that the two extension plates 74 move and unfold at the same time. When the extension plate 74 unfolds to the length required for processing the workpiece, the workpiece is placed in. After the workpiece is processed, the workpiece is taken out, and the extension plate 74 is retracted by the electric push rod 75.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
