Description

Technical Field

[0001] This utility model relates to the field of timber processing equipment technology, and in particular to a device for high-precision cutting of timber. Background Technology

[0002] Timber, commonly known as square timber, is sawn timber with a rectangular (including square) cross-section, which is produced by sawing logs (such as pine, fir, etc.). Its characteristics are standardization and ease of standardized production. It is mainly used for building support, formwork fixing, furniture frames and other applications.

[0003] In timber processing, various cutting methods present numerous challenges. For instance, if the timber's moisture content is not fully balanced, changes in environmental humidity after cutting can cause shrinkage or expansion, leading to dimensional drift or warping. Furthermore, uneven feed rates during manual or mechanical cutting can cause cutting deviations, increasing scrap rates due to dimensional errors or defects, and accelerating saw blade wear. Manual feeding also poses safety risks to operators; excessively high feed rates cause a rapid rise in cutter temperature, affecting cutting accuracy. Additionally, irregularly shaped timbers, due to the unidirectional fixation of the clamps, are prone to cutting deviations under the action of the cutter. Therefore, a cutting device capable of feeding timber at a uniform rate is needed to reduce manual labor, improve cutting accuracy, and minimize post-cutting finishing, thereby enhancing production quality and efficiency. Utility Model Content

[0004] This utility model addresses the technical problem of inconsistent fixing methods and cutting feed speeds during timber processing and cutting, which cause cutting offset and affect cutting accuracy. It provides a device for high-precision cutting of timber, including a cutting table and a cutter set in the center of the cutting table. A movable material carrier is provided above the cutting table, and a motor is provided under the cutting table. The motor is fixedly connected to the cutting table, and a threaded rod is fixedly connected to the output end of the motor.

[0005] A connector is connected to the lower part of the movable loading platform. The connector is sleeved around the cutting platform. The connector has a threaded through hole at its center. The internal thread of the threaded through hole matches the external thread of the threaded rod.

[0006] Two horizontal cylinders and two vertical cylinders are fixedly connected to each side of the movable loading platform. The output end of each horizontal cylinder is connected to a first gripper, and the output end of each vertical cylinder is connected to a second gripper.

[0007] Preferably, in the above technical solution, one side of each of the horizontal cylinders is embedded in the edge of the movable loading platform, and the edge of the movable loading platform is provided with two parallel grooves.

[0008] Preferably, in the above technical solution, the upper part of the cutting table is provided with two parallel "T"-shaped grooves, and the lower part of the movable material carrier is provided with a "T"-shaped slide bar that matches the "T"-shaped grooves.

[0009] Preferably, in the above technical solution, the bottom of the "T"-shaped groove is provided with at least one row of spherical grooves, and each of the spherical grooves is provided with a rotatable ball.

[0010] Preferably, in the above technical solution, the bottom of the "T"-shaped slider is provided with a groove that cooperates with the ball.

[0011] Preferably, in the above technical solution, a fixed connecting block is also provided under the cutting table. The fixed connecting block is fixedly connected to the bottom of the cutting table and is located at the other end corresponding to the motor.

[0012] Preferably, in the above technical solution, a bearing is provided in the center of the fixed connecting block, and the other end of the threaded rod passes through the bearing and is fixedly connected to the inner ring of the bearing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses a motor to drive a threaded rod to rotate, which in turn drives the moving platform to move horizontally. This ensures that the wood on the moving platform is fed and cut at a fixed rate, avoiding cutting deviation caused by uneven feed rate and accelerated blade wear due to rapid temperature rise, which would further affect the cutting accuracy of the wood.

[0015] This invention uses two sets of horizontal cylinders and two sets of vertical cylinders arranged opposite each other on both sides of the loading platform. The horizontal and vertical cylinders drive the air grippers to firmly fix the wood of various shapes to be processed in the horizontal and vertical directions, preventing the irregular wood from shifting during the cutting process if the fixing method is not stable enough.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] like Figures 1-5As shown, this utility model discloses a device for high-precision cutting of timber, including a cutting table 1 and a cutting blade 2 disposed in the center of the cutting table 1. A movable loading platform 3 is provided above the cutting table 1, and the movable loading platform 3 is attached to the upper surface of the cutting table 1. A motor 4 is provided under the cutting table 1, and the motor 4 is fixedly connected to the cutting table 1. A threaded rod 5 is fixedly connected to the output end of the motor 4. A connector 31 is connected below the movable loading platform 3, and the connector 31 is sleeved around the cutting table 1 in a circumferential manner. From the side, the connector 31 and the movable loading platform 3 are wrapped around and clamped around the cutting table 1. The connector 31 has a threaded through hole 311 at its center. The internal thread of the threaded through hole 311 matches the external thread of the threaded rod 5. When the threaded rod 5 rotates, the connector 31 can move horizontally under the drive of the thread. Two horizontal cylinders 32 and two vertical cylinders 33 are fixedly connected to each side of the movable loading platform 3. The output end of each horizontal cylinder 32 is connected to a first gripper 321, and the output end of each vertical cylinder 33 is connected to a second gripper 331. The four horizontal cylinders 32 are fixed to both sides of the movable loading platform 3 in a pairwise opposing manner, and the four vertical cylinders 33 are also fixed to both sides of the movable loading platform 3 in a pairwise opposing manner. The first gripper 321 connected to the horizontal cylinders 32 can fix the wood to be cut in the horizontal direction, preventing the wood from shifting during the cutting process and causing the cutting to deviate. The second pneumatic gripper 331 connected to the vertical cylinder 33 can compress and fix the wood to be cut in the vertical direction, working together with the moving platform 3 to achieve stable fixation of the wood to be cut. For some irregularly shaped wood, the four horizontal cylinders 32 and the four vertical cylinders 33 can be used to fix the irregularly shaped wood firmly on the moving platform 3 by adjusting the displacement distance of the different cylinders.

[0026] In this embodiment, one side of each horizontal cylinder 32 is embedded in the edge of the movable loading platform 3, and the edge of the movable loading platform 3 is provided with two parallel grooves 14. The upper surface of the horizontal cylinder 32 is flush with the upper surface of the movable loading platform 3 to increase the space for the first gripper 321 of the horizontal cylinder 32 to fit and fix the wood to be processed. The two parallel grooves 14 match the first gripper 321 of the horizontal cylinder 32, leaving space for the first gripper 321 of the horizontal cylinder 32 to extend and retract. The upper part of the cutting table 1 is provided with two parallel "T"-shaped grooves 13, and the lower part of the movable loading platform 3 is provided with "T"-shaped slide bars 35 that match the "T"-shaped grooves 13. The "T"-shaped slide bars 35 cooperate with the "T"-shaped grooves 13 to further improve the stability of the movable loading platform 3 during the movement, thereby improving the cutting accuracy of the wood to be processed. The bottom of the "T"-shaped groove 13 has at least one row of spherical grooves 15, and each spherical groove 15 contains a rotatable ball bearing 16. The bottom of the "T"-shaped slide bar 35 has a groove 351 that mates with the ball bearing 16. The ball bearing 16 and the corresponding groove 351 can reduce the friction during the movement of the moving platform 3. The groove 351 restricts the travel path of the ball bearing 16, further restricting the overall travel path of the moving platform 3, ensuring the stability of the moving platform 3 during travel, and improving the cutting accuracy of the wood to be processed.

[0027] It should be further noted that a fixed connecting block 12 is also provided under the cutting table 1. The fixed connecting block 12 is fixedly connected to the bottom of the cutting table 1 and is located at the opposite end of the motor 4. A bearing 121 is provided in the center of the fixed connecting block 12. The other end of the threaded rod 5 passes through the bearing 121 and is fixedly connected to the inner ring of the bearing 121. The bearing 121 in the fixed connecting block 12 can fix the other end of the threaded rod 5, avoiding the situation where the other end shakes during rotation when only one end is fixed to the output end of the motor 4, causing the moving material platform 3 to shake as well, affecting the cutting accuracy.

[0028] This invention utilizes a motor-driven threaded rod to rotate, which in turn drives the moving platform horizontally. This ensures the timber on the platform is fed and cut at a constant rate, preventing cutting deviation caused by uneven feed rates and accelerated blade wear due to rapid temperature increases, which would further affect the cutting accuracy of the timber. Two sets of horizontal cylinders and two sets of vertical cylinders are positioned opposite each other on both sides of the platform. These cylinders drive the grippers to securely fix the timber of various shapes in both the horizontal and vertical directions, preventing deviation during cutting, especially for irregularly shaped timber, if the fixing method is not secure enough. This invention solves the technical problem of cutting deviation and reduced cutting accuracy caused by inconsistent timber fixing methods and cutting feed rates during timber processing.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
