Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a Z-axis connection structure for woodworking machinery. Background Art

[0002] Woodworking machinery typically utilizes a three-axis feed system, with the X and Y axes used to adjust the board and processing position, and the Z axis used to control the feed of the output spindle. To improve processing efficiency, multiple output spindles are often used for simultaneous processing, placing a heavy load on the Z axis. If the Z-axis feed mechanism is insufficiently strong or mounted with insufficient precision, this can lead to spindle vibration, feed difficulties, and other issues, severely reducing processing quality.

[0003] The existing Z-axis feed mechanism mainly includes a screw, a guide rail and a Z-axis motor. A screw is fixedly installed in the vertical direction of the equipment. One end of the screw is driven by the Z-axis motor, and the other end of the screw is fixedly connected to the bearing 7. A feed slider is movably connected in the middle of the screw. The feed slider and the screw are rolled together. At the same time, the feed slider is fixedly connected to the mounting plate. Synchronous sliders that cooperate with the guide rails are respectively installed on both sides of the mounting plate. At this time, when the Z-axis motor drives the screw to rotate, thereby controlling the lifting and lowering of the output spindle on the Z-axis, due to production batch problems, the feed slider and the synchronous slider do not match, the feed slider will block the screw, causing the screw to be strained and reducing its service life.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0021] The technical solution of the present utility model is described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-3 As shown, the Z-axis connection structure for woodworking machinery described in the present invention includes a frame 1, a screw rod 11, a mounting plate 2 and a feed motor 3. The screw rod 11 is arranged on the frame 1 along the Z axis, and a transmission slider 12 is provided on the screw rod 11 in threaded transmission connection therewith, and the feed motor 3 is in transmission connection with the screw rod 11; the mounting plate 2 is mounted on the frame 1 through a guide structure, and an output motor 21 is provided on the mounting plate 2; a buffer structure is provided between the transmission slider 12 and the mounting plate 2, and the mounting plate 2 is fixedly connected to the transmission slider 12 through the buffer structure, so that the feed motor 3 can drive the output motor 21 to reciprocate along the Z axis on the frame 1. The mounting plate 2 and the frame 1 are slidably connected by the guide structure, so that the mounting plate 2 and the output motor 21 thereon can reciprocate along the Z axis. Of course, multiple output motors 21 or linkage shaft heads can be installed on the mounting plate 2.

[0023] Specifically, guide structures are provided on both sides of the frame 1, and both ends of the mounting plate 2 are fixedly connected to the guide structures, thereby ensuring balanced force between the mounting plate 2 and the guide structures.

[0024] Furthermore, the position between the mounting plate 2 and the frame 1 is limited by the guide structure, and a buffer structure is set between the transmission slider 12 and the mounting plate 2. The buffer structure can adjust the position error between it and the transmission slider 12, so that a Z-axial rigid lock is established between the transmission slider 12 and the mounting plate 2. No lateral locking force will be generated between the mounting plate 2 and the transmission slider 12, thereby ensuring the smoothness of the transmission of the screw rod 11.

[0025] If slight shape and position errors occur between structures later, they can be eliminated by reconnecting the buffer structure, which makes maintenance more convenient and can effectively extend the service life of the equipment.

[0026] The buffer structure includes a buffer block 22 and a free plane 13. The transmission slider 12 is provided with the free plane 13. The buffer block 22 is arranged on the free plane 13 and is fixedly connected to the transmission slider 12. The buffer block 22 is fixedly connected to the mounting plate 2 on one side. The free plane 13 is parallel to the horizontal plane. The mounting plate 2, the buffer block 22 and the transmission slider 12 are arranged in sequence along the horizontal direction. During the specific installation, the buffer block 22 is first fixedly connected to the mounting plate 2. The position of the buffer block 22 can be adjusted laterally along the free plane 13. Then, the buffer block 22 is fixed on the free plane 13. There is only a locking force in the Z-axis direction between the mounting plate 2 and the transmission slider 12 to avoid affecting the smoothness of the transmission of the screw 11.

[0027] The buffer block 22 is provided with a strip-shaped slot 23, which extends through the buffer block 22 along the Z axis and has a length parallel to the X axis. Bolts are provided in the strip-shaped slot 23 to securely connect the buffer block 22 to the free plane 13. When the buffer block 22 is adjusted along the free plane 13, the strip-shaped slot 23 can be securely connected to the transmission slider 12 via the bolts.

[0028] Furthermore, a plurality of fixing holes 24 are provided on one side of the buffer block 22 , and bolts are provided on the fixing holes 24 , and the bolts connect and fix the mounting plate 2 to the buffer block 22 .

[0029] The guide structure includes guide rails 14 and guide sliders 15. Guide rails 14 are provided on both sides of the frame 1 and are arranged parallel to the screw 11. The guide rails 14 are provided with a plurality of guide sliders 15 slidably connected thereto, and the ends of the mounting plate 2 are fixedly connected to corresponding guide sliders 15. The two sets of guide rails 14 and guide sliders 15 are symmetrically arranged. Of course, multiple guide sliders 15 can be provided on the guide rails 14, and the guide sliders 15 can be of the same specification. The mounting plate 2 and the guide sliders 15 can be directly leveled. There is no lateral locking force between the mounting plate 2 and the transmission slider 12, thus preventing structural stress from being generated between the guide sliders 15 and the guide rails 14, thereby improving the smoothness of the transmission of the screw 11.

[0030] The frame 1 is provided with two positioning blocks 16, each equipped with a bearing 17. The ends of the screw rod 11 are rotatably connected to the corresponding positioning blocks 16 via the bearings 17. The positioning blocks 16 ensure the stability of the ends of the screw rod 11 through the bearings 17. The feed motor 3 is fixedly mounted at the upper end of the frame 1 and connected to the upper end of the screw rod 11 via a coupling 31.

[0031] The rack 1 is provided with a sliding sleeve connector 18 , through which the rack 1 is mounted on the device, and the sliding sleeve connector 18 can slide to adjust the installation position.

[0032] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
