Description

Technical field:

[0001] The utility model relates to the technical field of profile milling processing, in particular to a precision milling device suitable for sawing processing equipment. Background technology:

[0002] In recent years, the door and window processing industry has developed many integrated and intelligent production equipment such as sawing processing centers, sawing and milling processing centers, and door and window processing production lines. The development and application of these products have greatly promoted the vigorous development of the door and window industry. At present, both sawing processing centers and sawing and milling processing centers use sawing processing equipment to saw profiles. This type of sawing processing equipment can mechanically clamp and export the sawed profiles (for example, a sawing and milling processing center disclosed in a Chinese patent, authorization announcement number: CN219053538U), which is not available in traditional single-head saw and double-head saw processing equipment. This feature provides the possibility for the subsequent development of new functions.

[0003] The layout of the existing sawing and milling processing center is to perform milling processing first and then sawing processing. The milling processing mainly relies on the gantry support design with four milling heads to mill the four sides of the profile respectively. The milling processing includes key holes, drainage grooves, glue injection holes, corner code holes and other processing. Due to the complexity of milling types and situations, the milling processing lags behind the sawing processing. In most cases, the sawing process is waiting for the milling process, which seriously restricts the overall processing efficiency of the sawing and milling processing center.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility model content:

[0005] The purpose of the utility model is to solve the problems existing in the prior art and to provide a precise milling device suitable for sawing processing equipment, so as to realize the milling processing of corner holes and glue injection holes of profiles after sawing. For the sawing processing center, an additional milling function is provided, and for the sawing and milling processing center, the front-end milling workload is reduced, the sawing waiting time is reduced, and the overall sawing and milling processing efficiency is improved.

[0006] The utility model achieves the above-mentioned purpose by adopting the following technical solutions:

[0007] Precision milling device applicable to sawing processing equipment, including a sawing frame. At the rear end of the sawing frame, there are two translational mechanisms which successively perform horizontal and vertical translations. At the ends of the two translational mechanisms, there is a mounting plate. On the mounting plate, there are two milling feed mechanisms arranged at intervals horizontally.

The milling feed mechanism uses a servo screw drive to drive the milling motor to feed longitudinally for milling the profile. One milling cutter is used for milling the corner code holes, and the other milling cutter is used for milling the glue injection holes.

[0008] The two translational mechanisms include a guide rail base horizontally arranged on the sawing frame. Horizontally on the guide rail base, there is a guide rail A. A sliding seat A is slidably arranged on the guide rail A. A reducer is provided on the sliding seat A. At the input end of the reducer, there is a motor A, and at the output end, there is a gear.

[0019] In order to more clearly explain the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] As Figures 1-6 shown, a precision milling device applicable to a sawing and machining equipment includes a sawing machine frame 1.

The glue injection hole means that the hole is pre-processed on the profile, and after the profile is assembled at the corner, sealant is injected through this hole for sealing.

A guide rail B209 is vertically arranged on the slider B208. A slide seat B210 is arranged on the guide rail B209. A nut seat B211 and a nut B212 are arranged on the slide seat B210. A lead screw B213 is vertically arranged on the nut B212. A pedestal bearing B214 and a motor seat B215 are arranged on the slide seat A203. A motor B216 is arranged on the motor seat B215. The lead screw B213 is rotatably arranged on the pedestal bearing B214 and is connected to the motor B216 through a coupling B217. The upper end of the slide seat B210 is provided with the mounting plate 3. It realizes horizontal and vertical translation in space, the overall operation is stable and reliable, and it can meet the milling requirements of glue injection holes and corner code holes of different profiles when cooperating with the existing sawing and processing equipment 7.

[0026] The milling feed mechanism 4 includes a feed slider 401 longitudinally arranged on the mounting plate 3. A feed guide rail 402 is arranged on the feed slider 401. A feed slide plate 403 is arranged on the feed guide rail 402. A feed nut seat 404 and a feed nut 405 are arranged on one side of the feed slide plate 403. A feed lead screw 406 is arranged on the feed nut 405. A pedestal bearing 407 and a motor seat 408 are arranged on the mounting plate 3. A feed motor 409 is arranged on the motor seat 408. The feed lead screw 406 is installed on the pedestal bearing 407 and is connected to the feed motor 409 through a coupling 410. A milling motor 5 is longitudinally arranged on the feed slide plate 403. The specific structure of the milling feed mechanism 4 is given. It is driven by a servo lead screw transmission for feeding, and can adjust the corresponding feed stroke according to the size of the profile to realize precise milling processing.
