Technical fields:
[0001] This utility model relates to the technical field of door and window profile processing equipment, and in particular to a profile grinding device for door and window processing. Background technology:
[0002] Door and window profiles require essential processes such as cutting and grinding during production. The basic structure of existing grinding equipment includes a grinding platform with grinding wheels on top to grind the profile surface. In order to prevent the profile from moving during grinding, a pneumatic clamping device is designed. However, door and window profiles are mostly thin-walled hollow structures with limited pressure resistance. The pneumatic clamping device and grinding device can easily squeeze the profile, causing micro-deformation, which affects the subsequent assembly of the profile and leads to assembly difficulties. This needs to be improved. Utility model content:
[0003] The purpose of this utility model is to provide a profile grinding device for door and window processing, so as to solve the technical problem that the existing profile grinding equipment is prone to deforming the profile, which leads to difficulties in subsequent assembly.
[0004] The present invention relates to a profile grinding device for door and window processing, comprising a frame frame with a horizontally opening sliding groove on the frame frame. A positioning rod matching the inner cavity of the door and window profile is slidably connected in the sliding groove. A meshing tooth is provided at the bottom end of the positioning rod, and the meshing tooth meshes with a gear shaft. The gear shaft is rotatably connected to the frame frame and is driven by a first electric motor. A feed port is provided at the outer end of the sliding groove. A grinding wheel is provided above the positioning rod and is driven by a second electric motor. The grinding wheel is rotatably connected to a moving rod, and the moving rod is driven by a transmission assembly.
[0005] Furthermore, the transmission assembly includes a lead screw, the moving rod is driven and screwed to the lead screw, the lead screw is rotatably connected to the frame, the lead screw is driven and connected to a third motor, and the moving rod is slidably connected to the frame.
[0006] Furthermore, sliding rods are horizontally connected to both sides of the movable rod, and sliding grooves are provided on the frame, with the sliding rods slidably connected to the sliding grooves.
[0007] Furthermore, a limiting block is connected to the positioning rod, the limiting block is located outside the frame, and an L-shaped limiting plate is connected outside the frame to limit the position of the positioning rod.
[0008] Furthermore, a limiting cylinder is connected at the opening of the sliding through groove. The limiting cylinder is located inside the frame, and the thickness of the limiting cylinder is less than the thickness of the door and window profile.
[0009] Furthermore, a guide angle is provided at the end of the positioning rod, and a rubber pad is installed inside the frame, with the rubber pad located below the positioning rod.
[0010] The beneficial effects of this utility model are as follows: This utility model has a simple structure, makes reasonable use of the profile's own structure, provides internal support and positioning for the profile, and eliminates the clamping device according to the stress characteristics of grinding, so that the door and window profiles are subjected to more uniform stress and do not deform during the grinding process, ensuring the subsequent assembly of the profiles, and is worth promoting and using.

[0015] In the figure, the frame frame 1, positioning rod 2, gear shaft 3, first motor 4, limit block 5, limit plate 6, grinding wheel 7, moving rod 8, lead screw 9, slide rod 10, feed port 11, rubber pad 12, door and window profile 13, and limit cylinder 14 are shown. Detailed implementation method:
[0016] like Figure 1 and Figure 2As shown, a profile grinding device for door and window processing includes a frame-shaped frame 1. A sliding groove is horizontally formed on the frame-shaped frame 1. A positioning rod 2, which matches the inner cavity of a door and window profile 13, is slidably connected in the sliding groove. In use, the door and window profile 13 is fitted onto the positioning rod 2. A meshing tooth is provided at the bottom end of the positioning rod 2. The meshing tooth meshes with a gear shaft 3. The gear shaft 3 is rotatably connected to the frame-shaped frame 1 and is driven by a first electric motor 4. An inlet 11 is formed at the outer end of the sliding groove, above the positioning rod 2. A grinding wheel 7 is provided, which is drivenly connected to a second electric motor. The grinding wheel 7 is rotatably connected to a moving rod 8, which is drivenly connected to a transmission assembly. The transmission assembly includes a lead screw 9, which is drivenly screwed to the moving rod 8. The lead screw 9 is rotatably connected to the frame frame 1 and is drivenly connected to a third electric motor. The moving rod 8 is slidably connected to the frame frame 1. Sliding rods 10 are horizontally connected to both sides of the moving rod 8. A sliding groove is provided on the frame frame 1, and the sliding rods 10 are slidably connected to the sliding groove.
[0017] like Figure 3 As shown, a limiting block 5 is connected to the positioning rod 2. The limiting block 5 is located outside the frame frame 1. An L-shaped limiting plate 6 is connected outside the frame frame 1. The limiting plate 6 is used to limit the position of the positioning rod 2.
[0018] like Figure 4 As shown, a limiting cylinder 14 is connected at the opening of the sliding through groove. The limiting cylinder 14 is located inside the frame frame 1, and the thickness of the limiting cylinder 14 is less than the thickness of the door and window profile 13. In order to ensure that the door and window profile 13 can be smoothly fitted onto the positioning rod 2, a guide angle is provided at the end of the positioning rod 2. A rubber pad 12 is installed inside the frame frame 1. The rubber pad 12 is located below the positioning rod 2. The rubber pad 12 can protect the door and window profile 13 from damage if it falls after grinding.
[0019] In specific work, such as Figures 1 to 4 As shown, firstly, start the first motor to move the positioning rod 2 forward until the limiting block 5 abuts against the frame frame 1. Then, install the door and window profile 13 at the feed inlet 11 so that the door and window profile 13 is fitted onto the positioning rod 2. Start the second and third motors to make the grinding wheel 7 grind the door and window profile 13 from right to left. Due to the force, the door and window profile 13 automatically abuts against the limiting cylinder 14. During the grinding process, the positioning rod 2 provides internal support to the door and window profile 13 to ensure that the door and window profile 13 does not deform. After grinding is completed, reverse the first motor to move the positioning rod 2 backward until the limiting block 5 abuts against the limiting plate 6. At this time, the door and window profile 13 automatically falls onto the rubber pad 12, thus completing the grinding.
[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
