Description

Technical Field

[0001] This utility model relates to the field of wood carving processing and positioning, specifically a positioning device for wood carving print engraving and printing. Background Technology

[0002] In the production process of woodblock prints, the carving and printing stages require extremely high precision and consistency in the design, making the positioning device a key factor affecting the quality of the artwork. With the booming development of the cultural and artistic industries, the market demand for woodblock prints is increasing, simultaneously placing higher demands on their craftsmanship and production efficiency.

[0003] Currently, most common positioning devices for wood carving prints use positioning plates to compress and limit the wood board, fixing its position by applying pressure in the horizontal direction. However, this positioning method can only restrict the movement of the wood board in a plane and cannot effectively limit its height, leading to vertical deviations during processing and affecting the accuracy of the wood carving. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a positioning device for wood carving and printing, which solves the shortcomings of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: a positioning device for wood carving and printing, comprising a worktable, a horizontal positioning plate fixed on the worktable, a positioning plate slidably disposed on the worktable, the positioning plate being parallel to the horizontal positioning plate, the positioning plate having the freedom to move away from or towards the horizontal positioning plate, two sets of longitudinal positioning components symmetrically disposed on the worktable, each longitudinal positioning component comprising a longitudinal positioning plate and a height positioning block, the longitudinal positioning plate being perpendicular to the horizontal positioning plate, the longitudinal positioning plate having the freedom to move towards or away from the horizontal positioning plate, a plurality of height positioning blocks being spaced apart on the end face of the longitudinal positioning plate near the horizontal positioning plate, the plurality of height positioning blocks being arranged at equal heights, and a wedge-shaped surface being provided at the bottom of the end of the height positioning block near the horizontal positioning plate.

[0006] Furthermore, a push cylinder is horizontally installed at the bottom of the workbench. The push cylinder is parallel to the longitudinal positioning plate. The positioning plate is connected to the telescopic shaft of the push cylinder via a connecting rod, which is shaped like a figure 7.

[0007] Furthermore, a lead screw groove is provided at the bottom of the worktable, the lead screw groove is parallel to the transverse positioning plate, a bidirectional threaded lead screw is rotatably installed in the lead screw groove, and lead screw sliders are threadedly fitted on the two opposite thread sections of the bidirectional threaded lead screw. The two longitudinal positioning plates are respectively connected to the two lead screw sliders through U-shaped connecting rods, and the U-shaped opening of the U-shaped connecting rods faces the horizontal direction.

[0008] Furthermore, a dustproof motor is installed at one end of the workbench, and the output shaft of the dustproof motor is driven by a bidirectional threaded lead screw.

[0009] Furthermore, the longitudinal positioning plate has an installation groove on its end face near the transverse positioning plate. The installation groove extends along the length of the longitudinal positioning plate, and the end of the height positioning block away from the wedge-shaped surface is slidably fitted into the installation groove.

[0010] Furthermore, each of the height positioning blocks is provided with a corresponding locking screw, which is threaded onto the top of the longitudinal positioning plate, and the tail of the locking screw is inserted into the mounting groove to abut against the height positioning block.

[0011] The beneficial effects of this utility model are:

[0012] First, the wood board is longitudinally positioned using the horizontal positioning plate and the positioning plate. Then, the two longitudinal positioning plates move closer to the wood board, and a limiting space is formed between the wedge-shaped surface of the height positioning block and the top surface of the worktable. The wood board enters the limiting space and rests against the wedge-shaped surface of the height positioning block. Thus, the horizontal and vertical positioning of the wood board is completed by the wedge-shaped surface of the height positioning block, so that the wood board will not deviate in the horizontal and vertical directions during subsequent processing, thereby improving the carving accuracy.

Detailed Implementation

[0018] Example 1

[0019] like Figures 1 to 4 As shown, a positioning device for wood carving and printing includes a worktable 1, a horizontal positioning plate 2 fixed on the worktable 1, and a positioning plate 3 slidably mounted on the worktable 1. The positioning plate 3 is parallel to the horizontal positioning plate 2 and has the freedom to move away from or towards the horizontal positioning plate 2. Two sets of longitudinal positioning components are symmetrically arranged on the worktable 1. Each longitudinal positioning component includes a longitudinal positioning plate 4 and height positioning blocks 5. The longitudinal positioning plate 4 is perpendicular to the horizontal positioning plate 2 and has the freedom to move towards or away from the horizontal positioning plate 2. Multiple height positioning blocks 5 are spaced apart on the end face of the longitudinal positioning plate 4 near the horizontal positioning plate 2. The multiple height positioning blocks 5 are arranged at the same height, and the bottom of the height positioning block 5 near the horizontal positioning plate 2 has a wedge-shaped surface. 6. Place the wood carving material (wood board) on the workbench 1, positioning it between the horizontal positioning plate 2 and the positioning plate 3. Then, the positioning plate 3 moves closer to the horizontal positioning plate 2, completing the longitudinal positioning of the wood board. Next, the horizontal positioning plate 2 moves the height positioning block 5 closer to the wood board. The wedge-shaped surface 6 of the height positioning block 5 forms a limiting space with the top surface of the workbench 1. The wood board enters this limiting space and rests against the wedge-shaped surface 6 of the height positioning block 5, pushing the wood board forward until the height positioning blocks 5 of the two vertical positioning plates 4 are firmly pressed against both ends of the wood board. Thus, the wedge-shaped surfaces of the height positioning blocks 5 complete the lateral and height positioning of the wood board, preventing horizontal and height deviations during subsequent processing and improving carving accuracy. In practice, to ensure the vertical positioning plates 4 can push the wood board on the horizontal positioning plates 2 and 3, the end faces of the horizontal positioning plates 2 and 3 that contact the wood board are smoothed. This ensures that after the wood board is longitudinally positioned, the vertical positioning plates 4 can still push the wood board for lateral positioning. In practice, an engraving machine is placed on one side of the workbench 1 to engrave prints on the positioned wooden board.

[0020] Example 2

[0021] Based on Example 1, such as Figure 1 and Figure 4As shown, the longitudinal positioning plate 4 has an installation groove 13 on its end face near the transverse positioning plate 2. The installation groove 13 extends along the length of the longitudinal positioning plate 4. The end of the height positioning block 5 away from the wedge-shaped surface 6 is slidably fitted into the installation groove 13, so that the installation position of the height positioning block 5 on the longitudinal positioning plate 4 is adjustable. The number and position of the height positioning blocks 5 can be adjusted according to the size of the wood board, and the positioning fixture can be adapted to different wood boards.

[0022] Furthermore, each height positioning block 5 is provided with a corresponding locking screw 14. The locking screw 14 is threaded onto the top of the longitudinal positioning plate 4. The tail of the locking screw 14 passes into the mounting groove 13 and abuts against the height positioning block 5. The height positioning block 5 is pressed onto the longitudinal positioning plate 4 by the locking screw 14, which facilitates the installation and removal of the height positioning block 5.

[0023] Example 3

[0024] Based on Example 2, such as Figures 1 to 3 As shown, a push cylinder 7 is horizontally installed at the bottom of the workbench 1. The push cylinder 7 is parallel to the longitudinal positioning plate 4. The positioning plate 3 is connected to the telescopic shaft of the push cylinder 7 through a connecting rod 8. The connecting rod 8 is shaped like a "7". The positioning plate 3 is moved by the telescopic movement of the push cylinder 7. Since a large amount of wood chips are generated during the wood carving process, in order to avoid the wood chips affecting the operation of the push cylinder 7, the push cylinder 7 is arranged at the bottom of the workbench 1. This can avoid the influence of wood chips. The "7" shaped connecting rod 8 can avoid the obstruction of the workbench 1 and move the positioning plate 3.

[0025] Example 4

[0026] Based on Example 3, such as Figures 1 to 3 As shown, a lead screw groove 9 is provided at the bottom of the worktable 1. The lead screw groove 9 is parallel to the transverse positioning plate 2. A bidirectional threaded lead screw 10 is rotatably installed in the lead screw groove 9. Lead screw sliders 11 are threaded onto the two opposite threaded sections of the bidirectional threaded lead screw 10. The two longitudinal positioning plates 4 are connected to the two lead screw sliders 11 respectively through U-shaped connecting rods 12. The U-shaped opening of the U-shaped connecting rods 12 faces the horizontal direction. A dustproof motor is installed at one end of the worktable 1. The output shaft of the dustproof motor is connected to the bidirectional threaded lead screw 10. The dustproof motor drives the bidirectional threaded lead screw 10. The lead screw 10 moves, causing its two lead screw sliders 11 to move axially along the double-threaded lead screw 10, and the two lead screw sliders 11 move in opposite directions. The lead screw sliders 11 drive the longitudinal positioning plates 4 to move through the U-shaped connecting rod 12, so that the two longitudinal positioning plates 4 can move synchronously closer to or away from the wooden board, thereby realizing the lateral positioning of the wooden board. The double-threaded lead screw 10 is arranged at the bottom of the worktable 1, which can avoid the influence of wood chips. At the same time, the setting of the U-shaped connecting rod 12 allows the lead screw sliders 11 to avoid the worktable 1 and drive the longitudinal positioning plates 4 to move.
