[0024] The following is in conjunction with the appendix Figs. 1-3 The specific embodiments of this utility model will be described in further detail.

[0025] Implementation examples, by Figs. 1-3 This utility model provides a positioning structure for wooden door processing, comprising:

[0026] The base 1 has a processing area 2 on one side of its top;

[0027] The L-shaped positioning component fixed in the middle of the processing area 2 is composed of a first positioning block 3 and a second positioning block 4 that are perpendicular to each other. At least one pair of first rollers 5 are embedded in the adjacent side of the first positioning block 3 and the second positioning block 4 respectively, and the rim of the first roller 5 protrudes 0.5-3mm from the edge of the positioning block.

[0028] A slide rail 12 is arranged parallel to the processing area 2, and a first U-shaped block 6 is slidably connected to the slide rail 12. The open end of the first U-shaped block 6 faces the processing area 2, and the piston rod of the cylinder 7 is connected to the outside of the closed end. The cylinder body of the cylinder 7 is fixed to the base 1.

[0029] A guide post 8 is set in the inner cavity of the first U-shaped block 6. A second U-shaped block 9 that can slide axially is sleeved on the guide post 8. Compression springs 10 are respectively sleeved on the guide posts 8 on both sides of the second U-shaped block 9. Second rollers 11 are embedded on both sides of the end of the second U-shaped block 9 facing the processing area 2. The rim of the second roller 11 protrudes from the outer surface of the second U-shaped block 9 and forms a rolling clamping area with the first roller 5 in the same plane.

[0030] Base 1 and processing area 2: the top side of the base 1 is provided with a processing area 2, which provides an operating space for wood door processing.

[0031] L-shaped positioning assembly: an L-shaped positioning assembly is fixed in the middle of the processing area 2, which is composed of a first positioning block 3 and a second positioning block 4 perpendicular to each other. At least one pair of first rollers 5 is embedded in the inner part of the adjacent side of the first positioning block 3 and the second positioning block 4, and the rim of the first roller 5 protrudes 0.5-3mm from the edge line of the positioning block. Such design enables the wood door to be initially positioned and guided by the first roller 5 when placed on the positioning block, and the design of the roller can reduce the friction between the wood door and the positioning block, reducing damage to the surface of the wood door.

[0032] Sliding and driving structure: a sliding rail 12 is arranged parallel to the processing area 2, and a first U-shaped block 6 is slidingly connected with the sliding rail 12. The opening end of the first U-shaped block 6 faces the processing area 2, and the closed end is connected with the piston rod of a pneumatic cylinder 7, and the cylinder body of the pneumatic cylinder 7 is fixed to the base 1. By the extension and retraction of the pneumatic cylinder 7, the first U-shaped block 6 can be driven to move horizontally along the sliding rail 12, thereby realizing the clamping or loosening operation of the wood door.

[0033] Elastic clamping structure: a guide column 8 is arranged in the inner cavity of the first U-shaped block 6, and an axially slidable second U-shaped block 9 is sleeved on the guide column 8. Compression springs 10 are respectively sleeved on the guide columns 8 on both sides of the second U-shaped block 9, and second rollers 11 are embedded on both sides of the end of the second U-shaped block 9 facing the processing area 2, the rims of the second rollers 11 protrude from the outer surface of the second U-shaped block 9, and the second rollers 11 are coplanar with the first rollers 5 to form a rolling clamping area. When the pneumatic cylinder 7 drives the first U-shaped block 6 to move towards the processing area 2, the second rollers 11 on the second U-shaped block 9 will gradually approach the wood door, and under the action of the compression springs 10, the wood door is elastically clamped, which can ensure the accuracy of positioning and avoid damage to the wood door caused by rigid clamping.

[0034] Further optimization of structure

[0035] Optimization of the second U-shaped block 9: the U-shaped opening width of the second U-shaped block 9 is three-fourths of the width of the second U-shaped block 9, and the inner wall is provided with a polyurethane buffer layer with a thickness of 2-5mm. Such design can further enhance the buffering protection effect on the wood door, preventing scratches or damage to the surface of the wood door during clamping.

[0036] Optimization of the cooperation between the guide column 8 and the second U-shaped block 9: a linear bearing is arranged between the guide column 8 and the second U-shaped block 9, and the outer wall of the linear bearing is in interference fit with the second U-shaped block 9, and the inner wall is in clearance fit with the guide column 8, and the cooperation tolerance is H7 / g6. The arrangement of the linear bearing can make the sliding of the second U-shaped block 9 on the guide column 8 more smooth and stable, improving the working precision and reliability of the positioning structure.

[0037] Slide rail 12 optimization: The slide rail 12 is a cross roller guide, and the ratio of the diameter of its rolling body to the curvature radius of the rolling groove of the bottom block of the first U-shaped block 6 is 1:1.05-1.2. The cross roller guide has high precision and rigidity, which can ensure the stability of the first U-shaped block 6 during sliding, thereby improving the accuracy of positioning.

[0038] Roller optimization: The surfaces of the first roller 5 and the second roller 11 are provided with spiral friction lines, the line depth is 0.2-0.5mm, and the pitch is 1 / 8-1 / 5 of the wheel diameter. The design of the spiral friction lines can increase the friction between the rollers and the wooden door, prevent the wooden door from sliding during processing, and further improve the reliability of positioning. At the same time, the axes of the first roller 5 and the second roller 11 are both perpendicular to the working plane of the processing area 2, which ensures the stability and accuracy of clamping the wooden door.

[0039] Working principle: Initial positioning: Place the wooden door on the L-shaped positioning assembly of the processing area 2, and the side edge of the wooden door contacts the first positioning block 3 and the second positioning block 4. At this time, the first roller 5 plays a key role, as its rim protrudes beyond the edge of the positioning block, the wooden door naturally adheres to the first roller 5 under the action of gravity, achieving preliminary positioning. At the same time, the first roller 5 reduces the sliding friction between the wooden door and the positioning block, reducing the wear on the surface of the wooden door.

[0040] Clamping action: Start the air cylinder 7, and the piston rod of the air cylinder 7 extends to push the first U-shaped block 6 along the slide rail 12 to move towards the processing area 2. As the first U-shaped block 6 approaches the wooden door, the second roller 11 on the second U-shaped block 9 also gradually approaches the wooden door. Because the second U-shaped block 9 can slide axially on the guide column 8, and the compression springs 10 on both sides of the guide column 8 are in an elastic state, when the second roller 11 contacts the wooden door, the compression springs 10 begin to compress, generating an elastic force. This elastic force causes the second roller 11 to act together with the first roller 5 to elastically clamp the wooden door from both sides. This elastic clamping method avoids damage to the wooden door that may be caused by rigid clamping, and at the same time, since the first roller 5 and the second roller 11 are coplanar to form a rolling clamping area, the wooden door can maintain good stability when clamped.

[0041] Stability during processing: During the processing of the wooden door, the spiral friction lines on the surfaces of the first roller 5 and the second roller 11 play an important role. These lines increase the friction between the rollers and the wooden door, effectively preventing the wooden door from sliding under the action of processing force. At the same time, the polyurethane buffer layer on the inner wall of the second U-shaped block 9 further buffers the vibrations and impact forces that may occur during processing, ensuring that the wooden door remains in a stable positioning state throughout the entire processing process.

[0042] Loosen operation: after processing, the piston rod of the cylinder 7 retracts, driving the first U-shaped block 6 away from the processing area 2. At this time, the compression spring 10 restores its original state, pushing the second U-shaped block 9 to reset, the second roller 11 separates from the wooden door, and the wooden door is loosened, making it easy to take out.

[0043] Method of use

[0044] Place the wooden door to be processed on the L-shaped positioning assembly of the processing area 2, so that the side of the wooden door contacts the first positioning block 3 and the second positioning block 4, and use the first roller 5 to achieve preliminary positioning and guidance.

[0045] Start the cylinder 7, the piston rod of the cylinder 7 extends, pushing the first U-shaped block 6 along the slide rail 12 to move towards the processing area 2. At this time, the second roller 11 on the second U-shaped block 9 gradually approaches the wooden door, and under the action of the compression spring 10, the second roller 11 and the first roller 5 jointly elastically clamp the wooden door, completing the positioning and clamping operation, and achieving diagonal automatic positioning and clamping of the door body.

[0046] During the processing of the wooden door, due to the spiral friction pattern on the surface of the first roller 5 and the second roller 11 and the elastic clamping effect, the wooden door can be effectively prevented from sliding, ensuring the smooth progress of the processing.

[0047] After processing, the piston rod of the cylinder 7 retracts, driving the first U-shaped block 6 away from the processing area 2, and the second U-shaped block 9 resets under the action of the compression spring 10, loosening the wooden door, so that the processed wooden door can be taken out.

[0048] Advantages: Precise positioning: through the cooperation of the L-shaped positioning assembly and the rolling clamping area, the wooden door can be precisely positioned, ensuring the accurate position of the wooden door during processing, improving the processing precision and reducing the waste rate.

[0049] Protect the surface of the wooden door: the design of the first roller 5 reduces the friction between the wooden door and the positioning block, reducing damage to the surface of the wooden door; the elastic clamping method of the second roller 11 and the first roller 5 avoids damage to the wooden door that may be caused by rigid clamping; at the same time, the polyurethane buffer layer on the inner wall of the second U-shaped block 9 further enhances the buffering protection effect on the wooden door, preventing scratches or damage to the surface of the wooden door during clamping, ensuring the appearance and quality of the wooden door.

[0050] Convenient to adjust: through the extension of the cylinder 7 to drive the first U-shaped block 6 to move along the slide rail 12, the clamping or loosening operation of the wooden door is realized, which can conveniently and quickly position and clamp wooden doors of different sizes, improving the processing efficiency and reducing the labor intensity.

[0051] The structure is stable and reliable: the linear bearing is arranged between the guide column 8 and the second U-shaped block 9, so that the sliding of the second U-shaped block 9 on the guide column 8 is smoother and more stable, the working precision and reliability of the positioning structure are improved; the cross roller guide rail is adopted for the slide rail 12, the cross roller guide rail has high precision and rigidity, and can ensure the stability of the first U-shaped block 6 in the sliding process, so that the positioning accuracy is improved; the spiral friction lines on the surfaces of the first roller 5 and the second roller 11 increase the friction between the rollers and the wooden door, the wooden door is prevented from sliding in the machining process, and the reliability of the positioning is further improved. The whole positioning structure has high stability and reliability, can be stably operated for a long time, and reduces the maintenance cost.
