Technical Field
[0001] This utility model relates to the technical field of milling and turning equipment, specifically to a rapid milling device for aluminum cover plates. Background Technology
[0002] Milling is a machining method that uses a milling cutter as a cutting tool to machine the surface of an object. Milling machines include horizontal milling machines, vertical milling machines, gantry milling machines, profile milling machines, universal milling machines, and lever milling machines.
[0003] A search revealed that this utility model discloses an aluminum mold milling device, with authorized Chinese patent publication number CN 221110812 U. This utility model belongs to the field of mold processing technology, specifically an aluminum mold milling device. It includes a worktable, a vertical column mounted on one side of the worktable, a horizontal column mounted on the side of the vertical column near the worktable, and a milling spindle mounted at the bottom of the side of the horizontal column away from the vertical column. An adjustment mechanism is provided at the top of the side of the worktable near the vertical column, and the adjustment mechanism is connected to a clamping mechanism via a clamping plate. In this utility model, the combined action of the adjustment mechanism and the clamping mechanism facilitates the operator's fixation of the workpiece, and reduces the need for excessive operator labor, thus improving work efficiency. The cleaning mechanism reduces the temperature of the milling spindle and milling cutter, and blows aluminum chips from the surface of the milling spindle and milling cutter to the outside of the workpiece, thereby improving work quality.
[0004] The milling device in the aforementioned patent still has some shortcomings. When existing aluminum cover plates are processed on milling machines, they are mostly clamped and fixed by simple fixtures. In order to enable the workpiece to move to adapt to the milling cutter, it is mostly driven by a screw. However, the drive screw set on the surface of the milling machine is easily affected by the debris falling during the milling process, thus affecting the normal translation drive. The debris falling near the screw is also difficult to clean, increasing the cleaning difficulty for workers. Utility Model Content

It solves the problem that when aluminum cover plates are machined on milling machines, they are mostly held and fixed by simple clamps. In order to allow the workpiece to move to adapt to the milling cutter, it is mostly driven by a screw. However, the drive screw set on the surface of the milling machine is easily affected by the debris falling during the milling process, thus affecting the normal translation drive. The debris falling near the screw is also difficult to clean, increasing the cleaning difficulty for workers.
[0006] This utility model provides the following technical solution: a rapid milling device for aluminum cover plates, including a milling machine bed, a tool support frame is provided at the middle of the top of the milling machine bed, a milling component is provided on the tool support frame, a workpiece positioning component is provided on the milling machine bed, an aluminum cover plate body is fixed on the workpiece positioning component, and support legs are evenly arranged around the bottom of the milling machine bed.
[0007] The workpiece positioning assembly includes a support base plate disposed in the middle of the milling machine bed. Two abutting connecting plates are symmetrically arranged on both sides of the support base plate. A push screw is rotatably and vertically arranged on the side of each abutting connecting plate. The end of each push screw is threaded through the support base plate. Two limiting slides are symmetrically opened on both sides of the milling machine bed. Limiting sliders are symmetrically fixed on both sides of the support base plate. The end of each limiting slider passes through the limiting slide and is vertically connected to a side connecting plate. Two fixing connecting plates are symmetrically fixed on both sides of the bottom of the milling machine bed. A drive screw is rotatably arranged between the two fixing connecting plates. A drive screw sleeve is fitted on the drive screw. A servo motor is mounted on the fixing connecting plate. The drive shaft of the servo motor rotatably passes through the fixing connecting plate and is fixedly connected to the end of the drive screw.
[0008] Preferred technical solution 1: Two driving connecting rods are symmetrically arranged on both sides of the driving screw sleeve, and the ends of the driving connecting rods are perpendicularly connected to the side of the side connecting plate.
[0009] Preferred technical solution 2: Each of the driving connecting rods is provided with a limiting rod inserted through it, and the end of each limiting rod is fixedly connected to the side of the fixed connecting plate.

[0015] This solution enables the servo motor to drive the drive screw to rotate more stably.
[0016] Compared with the prior art, this utility model provides a rapid milling device for aluminum cover plates, which has the following beneficial effects:
[0017] (1) This utility model is provided with a milling component and a workpiece positioning component on the milling machine body. The support base plate in the workpiece positioning component can support the aluminum cover plate body. The contact connecting plate is pushed by the push screw to hold the aluminum cover plate body. The movement of the support base plate is achieved by the drive screw pushing the drive screw sleeve. The side connecting plate drives the support base plate and the workpiece to accurately translate to the bottom of the milling component. Although this driving method also uses screw drive, it sets the screw at the bottom of the milling machine body. Therefore, when the aluminum cover plate body is milled by the milling component, the generated chips will only stay on the top side of the milling machine body and will not affect the rotation of the drive screw. This facilitates the cleaning of chips on the top of the milling machine body and effectively ensures the accurate positioning and translation of the workpiece, which is conducive to the high-precision machining of the workpiece.

[0024] Please see Figure 1-4 ,
[0025] Example 1: A rapid milling device for aluminum cover plates includes a milling machine bed 1, a tool support frame 2 is provided at the middle of the top of the milling machine bed 1, a milling component 3 is provided on the tool support frame 2, a workpiece positioning component 4 is provided on the milling machine bed 1, an aluminum cover plate body 5 is fixed on the workpiece positioning component 4, and support legs 6 are evenly arranged around the bottom of the milling machine bed 1.
[0026] The workpiece positioning assembly 4 includes a support base plate 401 disposed in the middle of the milling machine bed 1. Two abutting connecting plates 402 are symmetrically arranged on both sides of the support base plate 401. A push screw 403 is rotatably and vertically arranged on the side of each abutting connecting plate 402. The end of each push screw 403 is threaded through the support base plate 401. Two limiting slides 404 are symmetrically opened on both sides of the milling machine bed 1. Limiting sliders 405 are symmetrically fixed on both sides of the support base plate 401. The end of each limiting slider 405 passes through the limiting slide 404. The end of each limiting slider 405 is vertically connected to a side connecting plate 406. Two fixing connecting plates 407 are symmetrically fixed on both sides of the bottom end of the milling machine bed 1. A drive screw 408 is rotatably arranged between the two fixing connecting plates 407.
[0027] A drive screw sleeve 409 is fitted on the drive screw 408. A servo motor 410 is installed on the fixed connecting plate 407. The drive shaft of the servo motor 410 rotates through the fixed connecting plate 407 and is fixedly connected to the end of the drive screw 408. Two drive connecting rods 411 are symmetrically arranged on both sides of the drive screw sleeve 409. The ends of the drive connecting rods 411 are perpendicularly connected to the side of the side connecting plate 406. A limiting rod 412 is inserted through the drive connecting rods 411. The ends of the limiting rods 412 are fixedly connected to the side of the fixed connecting plate 407.
[0028] Example 2: The difference between this example and Example 1 is that the side of the contact connecting plate 402 is provided with anti-slip texture to increase friction.
[0029] This makes the contact connecting plate 402 more firmly fixed to the side of the aluminum cover plate body 5 after being pushed by the push screw 403.
[0030] Example 3: The difference between this example and Example 1 is that the bottom side of the support base plate 401 is in contact with the top side of the milling machine bed 1.
[0031] This makes the translation of the support base plate 401 on the surface of the milling machine bed 1 more stable.
[0032] Example 4: The difference between this example and Example 1 is that the side of the servo motor 410 is fixedly connected to the fixed connecting plate 407 through a connecting plate.
[0033] This enables the servo motor 410 to drive the drive screw 408 to rotate more stably.
[0034] In this embodiment, when existing aluminum cover plates are machined on milling machines, they are mostly clamped and fixed by simple fixtures. In order to enable the workpiece to move to adapt to the milling cutter, they are mostly driven by a screw. However, the drive screw set on the surface of the milling machine is easily affected by the debris falling during the milling process, which affects the normal translation drive. The debris falling near the screw is also difficult to clean, increasing the cleaning difficulty for workers.
[0035] In summary, in practical implementation, when the user needs to mill the aluminum cover plate body 5, the user first needs to place the aluminum cover plate body 5 on top of the support base plate 401 in the workpiece positioning assembly 4. The user can then rotate the push screw 403 to push the abutment connecting plate 402 to abut and clamp the side of the aluminum cover plate body 5, keeping the aluminum cover plate body 5 in a stable state at the bottom of the support base plate 401. Moreover, this device can also clamp and fix aluminum cover plate bodies 5 of different sizes.
[0036] Next, by setting limit sliders 405 on both sides of the support base plate 401, the limit sliders 405 slide through the limit slots 404, and the ends of the limit sliders 405 are vertically connected to the side connecting plates 406. When the user needs to push the aluminum cover plate body 5 to the bottom of the milling and turning component 3 for processing, the user can start the servo motor 410. The servo motor 410 drives the drive screw 408 to rotate. The drive screw 408 is fitted with a drive screw sleeve 409. The two sides of the drive screw sleeve 409 are connected to the side connecting plates 406 through the drive connecting rods 411. The drive connecting rods 411 are inserted through the limit inserts 412, so that the drive screw sleeve 409 can only move back and forth under the drive of the drive screw 408. The side connecting plates 406 drive the support base plate 401 to move back and forth in front of the top of the milling and turning machine bed 1, thereby accurately pushing the aluminum cover plate body 5 to the bottom of the milling and turning component 3 for processing.
[0037] This device sets the drive screw 408 on the bottom side of the milling machine bed 1. When the aluminum cover plate body 5 is milled by the milling component 3, the generated debris will only stay on the top side of the milling machine bed 1 and will not affect the rotation of the drive screw 408. Furthermore, the support base plate 401 is fitted to the top side of the milling machine bed 1, so that the debris falling onto the top side of the milling machine bed 1 and the support base plate 401 can be quickly cleaned up with simple sweeping. This effectively ensures the accurate positioning and translation of the workpiece, which is beneficial for the high-precision machining of the workpiece.
