Description

Technical Field

[0001] This utility model relates to the field of planar milling machine technology, specifically a planar milling machine with a side clamping mechanism. Background Technology

[0002] A milling machine is a versatile machine tool. It uses a milling cutter to mill workpieces. The milling cutter usually rotates as the main motion, while the movement of the workpiece and the milling cutter is the feed motion. Milling machines can machine planes, grooves, toothed parts, helical surfaces, and various curved surfaces. In addition, they can also be used for machining the surfaces and internal holes of rotating bodies and for cutting off parts.

[0003] However, existing planar milling machines still have some problems in use:

[0004] An existing example, application number CN202220333923.9, describes a planar milling machine with a side clamping function, which includes a base, a column welded to the top of the base, a spindle welded to the front side wall of the column, a milling cutter at the bottom of the spindle, a lifting mechanism welded to the top of the base, and a worktable welded to the top of the lifting mechanism. The worktable is hollow inside.

[0005] Existing planar milling machines mostly use rigid clamping blocks for clamping. Because they cannot conform to the surface contours of irregular workpieces, the force is uneven during clamping, and the workpiece is prone to shaking and displacement during processing, which seriously affects the processing accuracy and product quality. At the same time, due to the lack of adaptive adjustment function, the fixture needs to be changed frequently when dealing with irregular workpieces of different shapes, which greatly reduces processing efficiency and increases production costs.

[0006] Therefore, we propose a planar milling machine with a side clamping mechanism to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a planar milling machine with a side clamping mechanism to solve the problems mentioned in the background art, which mostly use rigid clamping blocks. Because these blocks cannot conform to the surface contour of irregular workpieces, uneven force is applied during clamping, and the workpiece is prone to shaking and displacement during processing, which seriously affects processing accuracy and product quality. At the same time, due to the lack of adaptive adjustment function, the fixtures need to be changed frequently when dealing with irregular workpieces of different shapes, which greatly reduces processing efficiency and increases production costs.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a planar milling machine with a side clamping mechanism, comprising a milling machine body and a worktable:

[0009] A worktable is fixed to the upper end of the milling machine body. Two sets of mounting seats are provided above the worktable. An adjusting screw is threaded through the middle of the mounting seat. A fixing plate is provided at one end of the adjusting screw. A clamping plate is attached to one side of the fixing plate. An outer cylinder is fixed to one side of the clamping plate. An inner rod is attached to and slidably connected to the middle of the outer cylinder. A spring is fixed inside the outer cylinder, and the other end of the spring is fixedly connected to the inner top of the inner rod. A rubber plate is attached to the outer surface of the inner rod.

[0010] By adopting the above technical solution, the clamping plate can be moved relative to the mounting base by manually rotating the adjusting screw. In conjunction with the elastic structure of the outer cylinder, inner rod, spring and rubber plate on one side of the clamping plate, it can adaptively clamp workpieces of different shapes, improve the clamping stability of irregular workpieces, reduce the risk of displacement during processing, and protect the workpiece surface from damage.

[0011] Preferably, the elastic mechanism composed of the outer cylinder, inner rod, spring and rubber plate is evenly distributed in several groups along one side of the clamping plate.

[0012] Using the above technical solution, when the clamping plate contacts the workpiece, several sets of outer cylinders, inner rods and springs independently extend and retract to adapt to the workpiece surface contour. The rubber plate increases the friction and buffers the contact stress, so as to disperse the clamping force through multi-point elastic support, achieve uniform pressing of irregular surfaces, improve the workpiece fixing reliability and avoid local deformation.

[0013] Preferably, the upper end face of the workbench is symmetrically provided with a plurality of positioning screw holes, and the middle part of the mounting base is provided with a threaded pin that is adapted to the positioning screw holes.

[0014] By adopting the above technical solution, the position of the mounting base can be fixed by screwing the threaded pin into the positioning screw hole of the worktable, so as to realize the rapid positioning of the side clamping mechanism on the mounting base, ensure the clamping position accuracy of the clamping plate, meet the clamping requirements of workpieces of different sizes, and facilitate the disassembly and adjustment of the mounting base.

[0015] Preferably, a handwheel is fixed to the other end of the adjusting screw, a bearing is installed at the connection between the adjusting screw and the fixed plate, and a fastening nut is provided on the outer surface of the adjusting screw and on one side of the mounting base.

[0016] Using the above technical solution, the handwheel is turned to drive the adjusting screw to rotate. The rotation of the adjusting screw is converted into linear motion through the bearing, so that the fixed plate can be adjusted to a horizontal position. Then, the fastening nut is rotated to make it abut against the mounting base, locking the position of the adjusting screw. This achieves manual and precise adjustment of the clamping plate spacing, prevents the screw from loosening due to processing vibration, and ensures stable clamping force.

[0017] Preferably, the four corners of the fixing plate are evenly distributed with buckles, and the four corners of the clamping plate are provided with slots, and the clamping plate and the fixing plate form an engaging structure through the buckles and slots.

[0018] Using the above technical solution, the clamping plate is connected to the four corners of the fixing plate by corresponding snap-fitting through the slots at the four corners, forming a detachable connection structure. This facilitates quick replacement of clamping plates of different specifications, adapts to diverse workpiece clamping needs, improves clamping effect, and ensures the stability of the workpiece processing process.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By evenly distributing an elastic mechanism consisting of an outer cylinder, inner rod, spring, and rubber plate on the surface of the clamping plate, the mechanism can adapt to the workpiece surface contour through the extension and contraction of the spring and the deformation of the rubber plate, ensuring a tight fit with the workpiece, dispersing the clamping force and protecting the workpiece. It can adaptively clamp according to different workpiece shapes, improve the clamping stability of irregular workpieces, reduce the risk of workpiece displacement during processing, meet the stability requirements of workpiece processing, facilitate adjustment and precise positioning, and improve the clamping stability and processing accuracy of irregular workpieces.

[0021] 2. The clamping plate is quickly installed and removed from the fixed plate through the snap-fit ​​and slot engagement structure. This allows for easy replacement of clamping plates of different specifications according to the processing requirements of different workpieces, so as to adapt to different workpiece clamping requirements, improve the clamping effect, and ensure the stability of the workpiece processing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] To address the issue of vibration affecting CNC machining centers due to the simultaneous operation of multiple components within the center, a solution is disclosed below. Please refer to [link / reference]. Figures 1-4 This utility model provides a technical solution: a planar milling machine with a side clamping mechanism, comprising a milling machine body 1 and a worktable 2. The worktable 2 is fixed to the upper end of the milling machine body 1. Two sets of mounting seats 4 are arranged above the worktable 2. An adjusting screw 6 is threaded through and connected to the middle of each mounting seat 4. A fixing plate 8 is provided at one end of the adjusting screw 6. A clamping plate 12 is attached to one side of the fixing plate 8. An outer cylinder 14 is fixed to one side of the clamping plate 12. An inner rod 15 is attached to and slidably connected to the middle of the outer cylinder 14. A spring 16 is fixed inside the outer cylinder 14, and the other end of the spring 16 is fixedly connected to the inner top of the inner rod 15. A rubber plate 17 is attached to the outer surface of the inner rod 15. Several sets of elastic mechanisms composed of the outer cylinder 14, inner rod 15, spring 16, and rubber plate 17 are evenly distributed along one side of the clamping plate 12. Several positioning screw holes 3 are symmetrically opened on the upper end face of the worktable 2. A threaded pin 5, compatible with the positioning screw holes 3, passes through the middle of the mounting seat 4. A handwheel 7 is fixed to the other end of the adjusting screw 6. A bearing 9 is installed at the connection between the adjusting screw 6 and the fixed plate 8. A fastening nut 10 is provided on the outer surface of the adjusting screw 6 and on one side of the mounting base 4. Buckles 11 are evenly distributed at the four corners of the fixed plate 8, and slots 13 are provided at the four corners of the clamping plate 12. The clamping plate 12 and the fixed plate 8 form a locking structure through the buckles 11 and the slots 13.

[0029] Rotating the handwheel 7 drives the adjusting screw 6 to rotate. One end of the adjusting screw 6 is connected to the fixed plate 8 via the bearing 9, enabling the lateral movement of the fixed plate 8. A fastening nut 10 is fitted onto the outer surface of the adjusting screw 6. After adjusting the position of the fixed plate 8, rotating the fastening nut 10 quickly locks the position of the adjusting screw 6 to prevent it from loosening during clamping. A clamping plate 12 is attached to one side of the fixed plate 8. The clamping plate 12 is quickly installed and removed from the fixed plate 8 via a snap-fit ​​structure of the buckle 11 and the slot 13. This allows for easy replacement of clamping plates 12 of different specifications to meet the different workpiece processing requirements. The outer side of the clamping plate 12 is equipped with an elastic structure consisting of an outer cylinder 14, an inner rod 15, a spring 16, and a rubber plate 17. The mechanism consists of multiple sets of elastic mechanisms evenly distributed along the outer surface of the clamping plate 12. When the workpiece is close to the rubber plate 17, the extension and contraction of the spring 16 and the deformation of the rubber plate 17 can adapt to the surface contour of the workpiece, ensuring close contact with the workpiece, dispersing the clamping force and protecting the workpiece. It can adaptively clamp according to different workpiece shapes, improve the clamping stability of irregular workpieces, and reduce the risk of workpiece displacement during processing. The two sets of mounting seats 4 on the worktable 2 cooperate with the positioning screw holes 3 on the worktable 2 through threaded pins 5. Multiple positioning screw holes 3 are designed to accurately adjust the position of the side clamping mechanism according to the position of the workpiece when it is placed, so as to meet the stability requirements during workpiece processing, facilitate adjustment and precise positioning, and improve the clamping stability and processing accuracy of irregular workpieces.

[0030] Working Principle: For this type of planar milling machine with a side clamping mechanism, the operator rotates the handwheel 7 to drive the adjusting screw 6 to rotate. The adjusting screw 6 drives the fixed plate 8 to make a horizontal linear movement. After adjustment, the operator rotates the fastening nut 10 to lock the position of the adjusting screw 6 to prevent loosening caused by processing vibration. The clamping plate 12 is quickly engaged with the fixed plate 8 through the four corner buckles 11 and the slots 13. Different specifications of clamping plates 12 can be replaced as needed to adapt to the clamping requirements of various workpieces. When the clamping plate 12 contacts the workpiece, the elastic mechanism composed of multiple sets of outer cylinders 14, inner rods 15, springs 16, and rubber plates 17 evenly distributed on its outer side adapts to the workpiece surface contour through the extension and contraction of the springs 16 and the deformation of the rubber plates 17, so that each contact point generates an independent elastic support force, which disperses the clamping force and avoids damage to the workpiece. This achieves stable clamping of workpieces of different shapes, improves workpiece stability, meets the clamping requirements of workpieces of different sizes, and improves adaptability.

[0031] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
