Description

Technical Field

[0001] This utility model relates to the field of woodworking technology, specifically to a round cutting mold frame for a woodworking trimming machine. Background Technology

[0002] In woodworking, when it is necessary to trim the edges of wooden boards or to groove the surface of a workpiece, a woodworking edge trimming machine is usually used for trimming and grooving. Although woodworking edge trimming machines can usually complete general trimming or straight-line cutting, when it is necessary to perform circular or arc-shaped cutting on the workpiece, existing woodworking edge trimming machines do not provide accessories to restrict their circular or arc-shaped cutting path, so that the woodworking edge trimming machine can accurately cut the workpiece along the predetermined circular or arc-shaped path. Therefore, most operators currently draw the circular or arc-shaped path to be processed on the workpiece first, and then cut it by hand. As a result, the circular or arc-shaped grooves processed on the workpiece are not only difficult to be accurate, but also difficult to obtain a flat surface, resulting in low practicality. To address this, we propose a circular cutting mold frame for a woodworking edge trimming machine. Utility Model Content

[0003] The technical problem this utility model aims to solve is to overcome the existing defects and provide a round cutting mold frame for a woodworking trimming machine. A positioning plate is nailed into the wood board to be processed through a matching positioning hole and a steel nail. Then, rotating the first handle drives the stud to rotate, which in turn moves the third arc-shaped plate upwards under the action of the limiting block and the limiting groove. This upward movement of the third arc-shaped plate prevents the optical axis from being pressed against, allowing the optical axis to move left and right to adjust the diameter of the cut circle. When the desired size is reached, the first handle is reversed to move the third arc-shaped plate downwards to press against the optical axis, preventing it from wobbling during processing. When the optical axis moves left and right, the pressure spring and the second arc-shaped plate prevent lateral movement, thus improving the practicality and effectiveness of the round cutting mold frame for the woodworking trimming machine. Furthermore, the optical axis has graduation lines; reading the graduation line value along the groove indicates the radius of the cut circle, effectively solving the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a round cutting mold frame for a woodworking trimming machine, comprising a mounting bracket, an optical shaft, fixing nails, and an adjustment assembly;

[0005] The upper surface of the mounting bracket is provided with a rounding component on the right side, and the upper surface of the left end of the mounting bracket is provided with two fixing buckles. The right end of the optical axis is located between the fixing buckles and the upper surface of the mounting bracket. Both ends of the fixing buckles are fixedly installed on the mounting bracket by fixing nails. The front end of the mounting bracket is provided with a handle component.

[0006] The adjustment assembly includes a positioning plate. An arc-shaped frame is mounted on the right side of the upper surface of the positioning plate. A stud is threaded onto the upper surface of the arc-shaped frame. A first handle is mounted on the upper end of the stud. A rotating shaft is mounted on the lower end of the stud. A third arc-shaped plate is rotatably mounted on the lower end of the rotating shaft. Limit blocks are mounted on both ends of the third arc-shaped plate. Limit grooves are formed on both sides of the inner surface of the arc-shaped frame. The limit blocks and limit grooves are slidably connected. Compression springs are mounted on both sides of the inner surface of the arc-shaped frame. A second arc-shaped plate is mounted on the outer end of the compression springs. The left end of the optical axis is located inside the arc-shaped frame, and the outer surface of the optical axis abuts against the concave surface of the second arc-shaped plate. Positioning holes are formed on both the front and rear sides of the left upper surface of the positioning plate. A groove is formed on the positioning plate, and the two ends of the groove correspond one-to-one with the two positioning holes.

[0007] Furthermore, the rounding assembly includes a trimming machine body and two elastic alloy brackets symmetrically mounted on the upper right side of the mounting bracket. A first arc-shaped plate is mounted on the upper end of each elastic alloy bracket, and mounting blocks are mounted on both ends of the first arc-shaped plate. The two facing mounting blocks are fixedly connected by bolts and nuts. The trimming machine body is located between the two elastic alloy brackets. A through hole is provided on the mounting bracket corresponding to the lower end of the trimming machine body. The trimming machine body is connected to a first plug via a first wire. The trimming machine body processes the wood board. The trimming machine body is detachable, allowing for disassembly and installation for maintenance and upkeep.

[0008] Furthermore, the handle assembly includes a second handle mounted on the front end of the mounting bracket. The second handle is connected to a tail plug via a second wire, and to a second plug via a third wire. The first plug and the tail plug are plugged in and out. The second plug is connected to an external power source, and the operator controls the trimming machine body via the second handle.

[0009] Furthermore, it also includes a long support plate. The upper right side surface of the positioning plate has fixing holes on both the front and back. The positioning plate is installed on the long support plate via the fixing holes and mounting bolts. The long support plate and the positioning plate, when integrated, can be used as a guide rail, allowing adjustment of the support plate according to the scale lines on the optical axis, and enabling slotting.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this woodworking trimming machine round cutting mold frame, the positioning plate is nailed into the wood board to be processed through one of the matching positioning holes and steel nails. Then, by rotating the first handle, the stud is driven to rotate. The rotation of the stud drives the third arc plate to move upward under the action of the limiting block and the limiting groove. The upward movement of the third arc plate prevents the optical axis from being pressed, so that the optical axis can move in the left and right directions to adjust the size of the cut circle diameter. When the desired size is adjusted, the first handle is reversed to make the third arc plate move downward to press against the optical axis, so as to prevent the optical axis from shaking during processing. When the optical axis moves in the left and right directions, the pressure spring and the second arc plate prevent the optical axis from moving laterally, thereby improving the practicality and use effect of the woodworking trimming machine round cutting mold frame. In addition, the optical axis is provided with scale lines. Reading the value of the optical axis scale line along the groove is the radius of the cut circle. Attached Figure Description

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.

[0015] Please see Figure 1-2 This embodiment provides a technical solution: a round cutting mold frame for a woodworking trimming machine, including a mounting bracket 7, an optical axis 6, a fixing nail 14, and an adjustment component;

[0016] The upper right side of the mounting bracket 7 is provided with a rounding component, and the upper left side of the mounting bracket 7 is provided with two fixing buckles 15. The right end of the optical axis 6 is located between the fixing buckles 15 and the upper surface of the mounting bracket 7.

A third arc-shaped plate 20 is rotatably mounted on the lower end of the rotating shaft. Limiting blocks 22 are mounted on both ends of the third arc-shaped plate 20. Limiting grooves 23 are formed on both sides of the inner interior of the arc-shaped frame 5. The limiting blocks 22 and the limiting grooves 23 are slidably connected. Compression springs 18 are mounted on both sides of the inner interior of the arc-shaped frame 5. A second arc-shaped plate 19 is mounted on the outer end of the compression springs 18. The left end of the optical axis 6 is located inside the arc-shaped frame 5, and the outer surface of the optical axis 6 abuts against the concave surface of the second arc-shaped plate 19. Positioning holes 17 are formed on both the front and rear sides of the upper left side of the positioning plate 1. A groove is formed on the positioning plate 1, with each end of the groove corresponding to one of the two positioning holes 17.

[0018] First, the positioning plate 1 is nailed into the wooden board to be processed through one of the matching positioning holes 17 and a steel nail. Then, by rotating the first handle 4, the stud 21 is rotated. The rotation of the stud 21 causes the third arc plate 20 to move upward under the action of the limiting block 22 and the limiting groove 23. The upward movement of the third arc plate 20 prevents the optical axis 6 from being pressed against, so that the optical axis 6 can move in the left and right directions to adjust the size of the cut circle. When the desired size is adjusted, the first handle 4 is reversed to make the third arc plate 20 move downward to press against the optical axis 6, so as to prevent the optical axis 6 from shaking during processing. When the optical axis 6 moves in the left and right directions, the compression spring 18 and the second arc plate 19 prevent the optical axis 6 from moving laterally, thereby improving the practicality and use effect of the woodworking trimming machine's round cutting mold frame. In addition, the optical axis 6 is provided with scale lines. Reading the scale line value of the optical axis 6 along the groove is the radius of the cut circle.

[0019] The rounding assembly includes a trimming machine body 9 and two elastic alloy brackets symmetrically mounted on the upper right side of a mounting bracket 7. A first arc-shaped plate 8 is mounted on the upper end of each elastic alloy bracket, and mounting blocks 16 are mounted on both ends of the first arc-shaped plate 8. The two facing mounting blocks 16 are fixedly connected by bolts and nuts. The trimming machine body 9 is located between the two elastic alloy brackets. A through hole is provided on the mounting bracket 7 corresponding to the lower end of the trimming machine body 9. The trimming machine body 9 is connected to a first plug 10 via a first wire. The trimming machine body 9 processes the wood board. The trimming machine body 9 is detachable, allowing for disassembly and installation for maintenance and upkeep.

[0020] The handle assembly includes a second handle 11 mounted on the front end of the mounting bracket 7. The second handle 11 is connected to a tail plug 12 via a second wire, and to a second plug 13 via a third wire. The first plug 10 and the tail plug 12 are plugged in and out. The second plug 13 is connected to an external power source, and the operator controls the trimming machine body 9 through the second handle 11.

[0021] It also includes a long support plate 3. The upper right side surface of the positioning plate 1 has fixing holes 2 on both the front and back. The positioning plate 1 is installed on the long support plate 3 through the fixing holes 2 and mounting bolts. The long support plate 3 and the positioning plate 1 are integrated and can be used as a ruler. The support plate can be adjusted according to the scale line value on the optical axis 6 to perform grooving.

[0022] The working principle of the round cutting mold frame of the woodworking trimming machine provided by this utility model is as follows: First, the positioning plate 1 is nailed into the wood board to be processed through one of the matching positioning holes 17 and steel nails. Then, by rotating the first handle 4, the stud 21 is driven to rotate. The rotation of the stud 21 drives the third arc plate 20 to move upward under the action of the limiting block 22 and the limiting groove 23. The upward movement of the third arc plate 20 prevents the optical axis 6 from being pressed, so that the optical axis 6 can move in the left and right directions to adjust the size of the cut circle. When the desired size is adjusted, the first handle 4 is reversed to make the third arc plate 20 move downward to press against the optical axis 6, so as to prevent the optical axis 6 from shaking during processing. When the optical axis 6 moves in the left and right directions, the compression spring 18 and the second arc plate 19 prevent the optical axis 6 from moving laterally, thereby improving the practicality and use effect of the round cutting mold frame of the woodworking trimming machine. In addition, the optical axis 6 is provided with scale lines. Reading the scale line value of the optical axis 6 along the groove is the radius of the cut circle. The edge trimming machine body 9 processes the wooden board. The edge trimming machine body 9 is detachable, allowing for easy disassembly and installation for maintenance. The second plug 13 connects to mains power, and the operator controls the edge trimming machine body 9 via the second handle 11. The long support strip 3, integrated with the positioning plate 1, functions as a ruler, allowing adjustment of the support strip according to the scale lines on the optical axis 6 for grooving.

[0023] It is worth noting that in this embodiment, the trimming machine body 9 can be freely configured according to the actual application scenario. At the same time, the second handle 11 controls the start and stop of the trimming machine body 9, which is safer and more convenient, and can be turned on and off at any time. The second handle 11 has a one-button locking function. After starting, the switch can be pressed to lock the device to keep it open. To close, the switch can be pressed to close it.
