[0002] A milling machine is a machine tool that can process the surface of a workpiece through a milling cutter. It is a widely used machine tool that can process flat surfaces and various curved surfaces. When the milling machine is working, the workpiece is mounted on a workbench or an accessory such as a dividing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or the milling head, and the workpiece can obtain the required processing surface.

[0003] Existing milling machines have some or all of the following deficiencies: 1. When the workpiece has two different surfaces, such as a convex curved surface on the front and a concave curved surface on the back. Only one of the surfaces can be polished at a time.

Therefore, two different devices are required to complete the processing of the two surfaces of the workpiece, resulting in high user costs. 2. During polishing, the milling cutter cannot conform to the surface of the workpiece, resulting in poor processing accuracy. 3. The structure for installing and disassembling the workpiece is relatively complicated, inconvenient to use, and the processing efficiency is slow. Utility Model Content

[0028] Reference Figure 1-Figure 7A profiling backing machine, which belongs to a type of milling machine, is mainly used for processing the front and back sides of wooden workpieces, and is suitable for processing workpieces with one side being an inner concave arc surface and the other side being an outer convex arc surface; it comprises a machine body 1, a feeding device 2 installed on the top of the machine body 1, the feeding device 2 comprises a slide plate 200 which can move back and forth, a workpiece clamping cylinder 3 is installed on the top of the slide plate 200, and a retractable workpiece pressing member 300 is installed on both sides of the workpiece clamping cylinder 3, which can be a pressing plate or an air claw; a support plate 201 is installed on both sides of the slide plate 200, and the area between the support plate 201 and the workpiece pressing member 300 is used to fix the workpiece; A spindle device 4 is installed on each side of the fuselage 1, which includes a connecting member 400, which can be a connecting plate or a connecting frame. The bottom of the first end of the connecting member 400 is connected to the lifting shaft of the lifting cylinder 401 installed on the fuselage 1, and the bottom of the second end of the connecting member 400 is hinged to the fixed seat 403 installed on the fuselage 1 through the optical axis 402. A bearing 404 rotatably connected to the optical axis 402 is installed on the fixed seat 403. A spindle 405 and a spindle motor 406 are correspondingly installed on the top of both ends of the connecting member 400. A milling cutter 407 is installed on the spindle 405 near one end of the slide plate 200, and a synchronous belt 408 is installed between the rotating shafts of the spindle 405 and the spindle motor 406.

[0029] When in use, the two workpieces are placed on the slides 200 on both sides of the workpiece clamping cylinder 3, the workpiece clamping cylinder 3 is started, and the two workpiece pressing parts 300 push the two workpieces against the template 201 respectively, and finally the two workpieces are fixed, the spindle motor 406 and the feeding device 2 are started, and the spindle motor 406 drives the spindle 405 and the milling cutter 407 to rotate via the synchronous belt 408, and the feeding device 2 drives the slide 200 and the two workpieces to move forward in a straight line in the direction of the milling cutter 407, and then the two milling cutters 407 process the front sides of the two workpieces respectively. When the processing is completed, the two lifting cylinders 401 simultaneously push the first end of the connecting member 400 upwards to separate the two milling cutters 407 from the workpieces, and then the feeding device 2 drives the slide 200 and the two workpieces to retreat, and finally reset to the initial position, and then remove the workpiece, and then the above two workpieces can be installed in reverse to process the other side, or two new workpieces can be installed for processing. The present invention can process two workpieces at the same time, thus improving processing efficiency, reducing user use costs and saving factory space. The installation and removal of workpieces are simple and easy to use.

[0030] In some embodiments, the feeding device 2 includes two linear guide rails 202 installed on the top of the fuselage 1, a screw seat 203 symmetrically installed between the two guide rails 202, a screw 204 connected to the two screw seats 203, a feeding motor 205 connected to one end of the screw 204, and a nut seat 206 threadedly connected to the screw 204. The nut seat 206 is connected to the bottom of the skateboard 200, and the skateboard 200 is slidingly connected to the two guide rails 202 through a slider 207; when the feeding motor 205 rotates, the screw 204 rotates synchronously, and then the nut seat 206 and the skateboard 200 slide forward or backward along the two guide rails 202 through two sets of sliders 207. The structure is simple, the operation is stable and reliable, and the processing accuracy can be improved.

[0031] In some embodiments, a spindle motor adjustment assembly 409 is also included, which includes a motor base 409a, and the spindle motor 406 is installed on the motor base 409a. The first end of the motor base 409a is hinged to the connecting member 400 through a pin shaft 409b, and a U-shaped slot 409c is opened at the second end of the motor base 409a. An adjustment rod 409d is hinged on the connecting member 400 near one end of the slot 409c, which is preferably a screw. The adjustment rod 409d can rotate and can enter the slot 409c to be fixed together with the spindle motor 406. This structure can change the spacing adjustment between the spindle motor 406 and the spindle 405, thereby changing the tightness of the synchronous belt 408 during installation. Installing or removing the synchronous belt 408, as well as adjusting the synchronous belt 408 are very convenient and have good applicability.

[0032] In some embodiments, a plurality of positioning plates 406a are regularly arranged on the outer wall of the spindle motor 406. The positioning plates 406a arranged at different heights can facilitate the rearward positioning of the free end of the adjusting rod 409d, thereby realizing the angle adjustment of the spindle motor 406. A limiting nut is threadedly connected to the adjusting rod 409d. After adjusting the angle of the spindle motor 406 or the height from the ground, the limiting nut is tightened to fix the adjusting rod 409d in the slot 409c of the motor seat 409a to avoid displacement and improve stability.

[0033] In some embodiments, two milling cutters 407 are installed on two main spindles 405, one of which is used to process the inner concave arc surface of the workpiece, and the other is used to process the outer convex arc surface of the workpiece. This structural design allows the two milling cutters 407 to correspondingly process the inner concave arc surface and the outer convex arc surface of the two workpieces. Then, the two workpieces are removed and the installation positions of the two workpieces are exchanged to complete the processing of the other sides of the two workpieces. In this way, only one machine is needed to complete the processing of two different surfaces of the workpiece, thereby reducing user usage costs and saving factory space.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
