Description

Technical Field

[0001] This utility model relates to the field of milling technology, specifically a vertical milling device. Background Technology

[0002] A milling machine is an electromechanical integrated processing equipment system based on the milling cutting principle. It achieves material removal and forming of the workpiece through the relative motion between a rotating multi-edged milling cutter and a workpiece that feeds along a preset trajectory. Its core function is to process the workpiece blank into mechanical parts with specific dimensional accuracy, geometric tolerances and surface quality through the periodic cutting action of the milling cutter. It is widely used in fields such as machinery manufacturing, aerospace, and automotive industries.

[0003] When fixing a workpiece during milling, existing workpiece clamping methods typically involve line contact or surface contact. Currently, triangular point contact clamping is only used when machining round workpieces. For general shapes, workpieces are clamped by bolts and pressure plates, which either involve surface contact or line contact. Because surface contact or line contact results in a single force distribution, the force balance between line contact and surface contact is easily disrupted once the direction of the cutting force changes, leading to workpiece movement.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a vertical milling processing device. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a vertical milling processing device, which solves the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a vertical milling processing device, including a machine body, a frame fixed on the top of the machine body, a worktable slidably mounted on the top of the frame, a positioning and clamping mechanism provided on the top of the worktable, the positioning and clamping mechanism including an adjustment component and a clamping block, the clamping block being used to clamp the surface of the workpiece;

[0007] The worktable has fixed rods at both ends for limiting the position. The clamping block is sleeved on the surface of the fixed rod and slides in contact with the fixed rod. An adjusting rod is sleeved behind the clamping block. The surface of the adjusting rod has multiple fan-shaped adjusting grooves. An insert is fixed behind the clamping block and outside the adjusting rod. The insert can be inserted into the adjusting groove on the surface of the adjusting rod. By rotating the adjusting rod, the distance between two adjacent clamping blocks can be adjusted according to the length of the workpiece to achieve multi-point clamping.

[0008] As a preferred technical solution of this utility model, the adjustment component includes a moving rod and a threaded rod II. The threaded rod II is rotatably installed at both ends of the worktable. A sliding seat is sleeved on the surface of the threaded rod II. The fixed rod is embedded in the sliding seat and slidably connected to the inside of the sliding seat. Two opposing threaded grooves are opened on the surface of the threaded rod II. Rotating the threaded rod II causes the fixed rod and the sliding seat to move closer to or further away from the center of the worktable on the surface of the threaded rod II.

[0009] As a preferred embodiment of this utility model, the sliding seat and the fixed rod are hinged to a hinge block at the same horizontal line. When the hinge block is unfolded, the hinged position with the sliding seat remains unchanged, only causing the fixed rod to rise.

[0010] As a preferred technical solution of this utility model, the bottom of the worktable is provided with a rotatable threaded rod I, and the movable rod is sleeved on the surface of the threaded rod I. There are two movable rods distributed at both ends of the worktable. The rotation of the threaded rod I drives the two movable rods to move closer to or further away from the worktable.

[0011] As a preferred technical solution of this utility model, a pressure block that only contacts but does not connect is sleeved at the middle hinge point of the hinge block. A sliding contact pressure rod passes through the surface of the pressure block. The two moving rods move back and forth on the surface of the threaded rod I, causing the pressure rod to squeeze the hinge block and causing the fixed rod and clamping block to rise according to the height of the workpiece.

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

[0013] The distance between two adjacent clamping blocks can be adjusted by rotating the adjustment rod. When clamping a long workpiece, the clamping blocks can be distributed to clamp at multiple points. By distributing the stress, the workpiece is subjected to more uniform force during processing, avoiding shaking and displacement that would affect the processing accuracy.

[0021] 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.

[0022] Please see Figure 1-6 As shown, a vertical milling processing device includes a body 1, a frame 2 fixed on the top of the body 1, a worktable 3 slidably mounted on the top of the frame 2, and a positioning and clamping mechanism on the top of the worktable 3. The positioning and clamping mechanism includes an adjustment component and a clamping block 301, which is used to clamp the surface of the workpiece.

[0023] The worktable 3 has fixed rods 307 at both ends for limiting the position. The clamping block 301 is sleeved on the surface of the fixed rod 307 and slides in contact with the fixed rod 307. An adjusting rod 302 is sleeved behind the clamping block 301. The surface of the adjusting rod 302 has multiple adjusting grooves distributed in a fan shape. An insert block 3011 is fixed behind the clamping block 301 and outside the adjusting rod 302. The insert block 3011 can be inserted into the adjusting groove on the surface of the adjusting rod 302. By rotating the adjusting rod 302, the distance between two adjacent clamping blocks 301 can be adjusted according to the length of the workpiece to achieve multi-point clamping.

[0024] In one specific embodiment of this utility model, the adjustment assembly includes a moving rod 304 and a threaded rod II 305. The threaded rod II 305 is rotatably mounted at both ends of the worktable 3. A sliding seat 310 is sleeved on the surface of the threaded rod II 305. A fixed rod 307 is embedded inside the sliding seat 310 and slidably connected to the inside of the sliding seat 310. Two opposing threaded grooves are opened on the surface of the threaded rod II 305. Rotating the threaded rod II 305 causes the fixed rod 307 and the sliding seat 310 to move closer to or further away from the center of the worktable 3 on the surface of the threaded rod II 305.

[0025] In one specific embodiment of this utility model, the sliding seat 310 and the fixed rod 307 are hinged to a hinge block 308 at the same horizontal line. When the hinge block 308 is unfolded, the hinged position with the sliding seat 310 remains unchanged, only driving the fixed rod 307 to rise.

[0026] As a specific embodiment of this utility model, the bottom of the workbench 3 is provided with a rotatable threaded rod I 303, and a movable rod 304 is sleeved on the surface of the threaded rod I 303. There are two movable rods 304 distributed at both ends of the workbench 3. The rotation of the threaded rod I 303 drives the two movable rods 304 to move closer to or further away from the workbench 3.

[0027] In one specific embodiment of this utility model, a pressure block 309 is sleeved at the middle hinge point of the hinge block 308, which only contacts but does not connect with the hinge block 309. A sliding contact pressure rod 306 passes through the surface of the pressure block 309. Two moving rods 304 move back and forth on the surface of the threaded rod I 303, which drives the pressure rod 306 to press the hinge block 308, thereby causing the fixed rod 307 and the clamping block 301 to rise and be adjusted according to the height of the workpiece.

[0028] When in use, the workpiece to be processed is placed on the top of the worktable 3, and then the workpiece is clamped by the clamping block 301 so that the device can process it. By rotating the threaded rod II 305, the distance between the two clamping blocks 301 can be adjusted according to the size of the workpiece. The clamping block 301 has toothed blocks at the position where it clamps the workpiece surface, which can further fix the workpiece during processing.

[0029] The adjusting rod 302 has multiple fan-shaped adjusting grooves on its surface. The clamping block 301 passes through the adjusting rod 302 from the rear and is inserted into the adjusting groove on the surface of the adjusting rod 302 through the corresponding insert block 3011. By rotating the adjusting rod 302, the distance between two adjacent clamping blocks 301 can be adjusted. When clamping a long workpiece, the clamping blocks 301 can be distributed to clamp at multiple points. By dispersing the stress, the workpiece is subjected to more uniform force during processing, avoiding shaking and displacement that affect the processing accuracy.

[0030] By rotating 311, the moving rods 304 at both ends are pushed to move towards the middle position of the worktable 3, while the pressure rod 306 is driven to squeeze the hinge block 308. This causes the hinge block 308 to drive the fixed rod 307 and the clamping block 301 to move upward. This can raise and clamp the workpiece to constrain the high position of the workpiece, and avoid the phenomenon of shaking and displacement caused by the force being located on the upper part of the workpiece during milling.
