Description

Technical Field

[0001] This utility model relates to the field of furniture processing equipment technology, and in particular to a positioning device for cutting functional cabinets. Background Technology

[0002] In the production and manufacturing process of functional cabinet panel furniture, the cutting of the boards is a key process that determines the quality of the finished product. In order to ensure the cutting accuracy and dimensional consistency, positioning devices are usually used to fix and position the boards to ensure that the boards remain stable and do not shift during processing.

[0003] However, in actual processing scenarios, the cabinet structure of functional cabinets is complex, and the thickness and specifications of the boards used are numerous. Most existing cutting positioning devices adopt bolt fastening or fixed stroke cylinder clamping methods. This rigid fixed structure lacks flexibility. When it is necessary to process boards of different thicknesses, operators often need to manually adjust the stroke of the clamp or change the positioning blocks of different specifications. This not only greatly increases the labor intensity of workers and prolongs the auxiliary operation time, resulting in low production efficiency, but also, due to the difference in the precision of manual adjustment, it is easy to cause excessive clamping force to damage the surface of the board or insufficient clamping force to cause the board to loosen. It is difficult to meet the needs of modern furniture production for efficient and flexible processing.

[0004] Therefore, this utility model proposes a positioning device for cutting functional cabinets to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the positioning device for cutting functional cabinets, such as difficulty in automatically adapting to the stable clamping of plates of different thicknesses, cumbersome manual adjustment leading to low processing efficiency, and lack of effective fixation of auxiliary measuring tools resulting in positioning deviation, this utility model aims to provide a positioning device for cutting functional cabinets with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a positioning device for cutting a functional cabinet, including: a support base, and a fixed frame fixedly connected to the top of the support base; and a linkage clamping assembly composed of a lifting plate, a rotating plate, a moving block and a spring column.

[0007] The movable block has a rectangular block structure that slides in conjunction with the square groove, and the spring post II has an elastic structure that provides a restoring force.

[0008] Furthermore, the inner wall of the support base is provided with a square groove, the movable block is slidably connected to the inner wall of the square groove, a spring column two is fixedly connected to the front side of the movable block, the end of the spring column two away from the movable block is fixedly connected to the front side of the inner wall of the square groove, a lifting plate is provided below the fixed frame, a rotating plate is rotatably connected to the outer wall of the lifting plate, and the end of the rotating plate away from the lifting plate is rotatably connected to the bottom of the inner wall of the movable block. The lifting plate moves downward under pressure, causing the rotating plate to rotate, thereby causing the movable block to slide horizontally in the square groove and squeeze the spring column two, realizing mechanical linkage adaptive clamping.

[0009] Preferably, a guide groove is provided on the bottom right side of the inner wall of the square groove, and a sliding plate is fixedly connected to the right side of the moving block. The sliding plate is slidably connected to the inner wall of the guide groove, and the sliding plate reciprocates along the length of the guide groove, thereby increasing the stability of the moving part during the adjustment process.

[0010] Preferably, the positioning device for cutting the functional cabinet further includes a positioning post, a positioning hole one is provided on the top of the outer wall of the support base, a positioning hole two is provided on the inner wall of the sliding plate, and the positioning post is located at the intersection of the positioning hole one and the positioning hole two, for insertion and locking after the position of the moving block is determined.

[0011] Preferably, a limiting mechanism is fixedly connected to the left side of the fixing frame. The limiting mechanism includes a limiting post fixedly connected to the left side of the fixing frame. The top of the outer wall of the limiting post is provided with a placement groove for placing a ruler, which provides an installation reference for the ruler used for auxiliary measurement.

[0012] Preferably, a fixing plate is fixedly connected to the top of the fixing frame, a fixing column is vertically fixedly connected to the bottom of the outer wall of the fixing plate, and a rotating ring is rotatably connected to the outer wall of the fixing column, the rotating ring being able to rotate around the axis of the fixing column.

[0013] Preferably, a limiting plate is fixedly connected to the bottom of the outer wall of the rotating ring, and a spring post is fixedly connected to the right side of the limiting plate. The end of the spring post away from the limiting plate is fixedly connected to the bottom right side of the fixed plate, so as to use the tension of the spring itself to drive the limiting plate to reset.

[0014] Preferably, a groove is provided on the top right side of the outer wall of the limiting post, the bottom of the outer wall of the rotating ring is slidably fitted to the inner wall of the groove, and one end of the limiting plate extends to the top of the placement groove, thereby forming a downward flexible pressure on the scale located in the placement groove.

[0015] Preferably, the cross-sectional shape of the placement groove is rectangular, the sliding groove is an arc-shaped groove, and the fixing plate, the limiting column and the support base are integrally formed to ensure the overall mechanical strength and assembly accuracy of the device.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem that existing positioning devices cannot automatically adapt to plates of different thicknesses and require frequent manual adjustment of the fixture, resulting in low processing efficiency. It achieves self-adaptive fixing of plate thickness, simplifies the operation process, reduces changeover costs, and improves processing efficiency.

[0018] 2. This utility model solves the problem of insufficient connection rigidity or loosening caused by processing vibration that may occur when relying solely on spring force for clamping by setting guide grooves on the side of the moving block to cooperate with the sliding plate, and combining the positioning holes and positioning columns on the outer wall of the support base and the inner wall of the sliding plate. It achieves secondary rigid locking after initial elastic adaptive clamping, ensuring the absolute stability of the plate when the fixed frame and spring column cooperate to clamp it, and improving processing efficiency.

[0019] 3. This utility model solves the problem of existing devices lacking effective fixation of auxiliary measuring tools and easily causing size reference deviation by setting a limiting mechanism including a limiting post, a rotating ring, a limiting plate and a spring post on the side of the fixed frame. The limiting plate is driven to rotate by the torque of the spring and flexibly presses the scale placed in the slot. This achieves automatic and flexible limiting of the scale, complete locking of the size reference, avoidance of positioning deviation and prevention of scale wear. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 6 This utility model provides a positioning device for cutting a functional cabinet, including a support base 1 for mounting the base and a fixing frame 13 fixedly connected to the top of the support base 1. The support base 1 provides a stable support platform for the entire device, and the fixing frame 13 serves as the contact reference surface for the top of the plate. A square groove 3 is provided on the inner wall of the support base 1, which provides a horizontal guiding space inside. A movable block 8 is slidably connected to the inner wall of the square groove 3. The movable block 8 can reciprocate horizontally along the length direction of the square groove 3. A spring column 2 11 is fixedly connected to the front side of the movable block 8. The end of the spring column 2 11 away from the movable block 8 is fixedly connected to the front side of the inner wall of the square groove 3. The elastic restoring force of the spring column 2 11 can provide a reset for the movable block 8.

[0031] Please refer to Figure 1 and Figure 6 A lifting plate 10 is provided below the fixed frame 13. The lifting plate 10 is a direct force-bearing component. A rotating plate 9 is rotatably connected to the outer wall of the lifting plate 10. The rotating plate 9 is a linkage mechanism that transmits motion. The end of the rotating plate 9 away from the lifting plate 10 is rotatably connected to the bottom of the inner wall of the moving block 8. When the plate is placed in and presses the lifting plate 10 to move downward, the vertical displacement of the lifting plate 10 is converted into a horizontal thrust on the moving block 8 through the angle of the rotating plate 9. This causes the moving block 8 to slide horizontally in the square groove 3 and squeeze the spring column 11. The reaction force of the spring column 11 is used to make the lifting plate 10 press against the plate upward, thereby achieving adaptability to plates of different thicknesses.

[0032] Please refer to Figure 1 , Figure 3 and Figure 4 A guide groove 4 extending horizontally is provided on the bottom right side of the inner wall of the square groove 3. The guide groove 4 provides additional support and a guiding path for the sliding component. A sliding plate 6 is fixedly connected to the right side of the moving block 8. The cross-sectional shape of the sliding plate 6 is adapted to the inner wall of the guide groove 4. The sliding plate 6 is slidably connected in the inner wall of the guide groove 4. This fitting structure in which the sliding plate 6 is embedded in the guide groove 4 ensures that the moving block 8 can reciprocate strictly along the length direction of the guide groove 4 when it is subjected to force, effectively preventing the moving block 8 from tilting or getting stuck in the square groove 3, thereby ensuring the smoothness of force transmission.

[0033] Please refer to Figure 1 and Figure 4 The support base 1 has a positioning hole 5 on the top of its outer wall, and the sliding plate 6 has a positioning hole 7 on its inner wall. The positioning device for cutting the functional cabinet also includes a positioning post 12. The outer diameter of the positioning post 12 matches the diameter of the positioning hole 5 and the positioning hole 7. When the moving block 8 moves the sliding plate 6, the positioning post 12 can be inserted into and slidably connected in the inner walls of the positioning hole 5 and the positioning hole 7. By passing the positioning post 12 through the positioning hole 5 and the positioning hole 7, the position of the moving block 8 can be locked. The initial elastic clamping achieved by the spring post 11 and the secondary rigid locking achieved by the positioning post 12 ensure the stability of the plate when the fixed frame 13 and the spring post 11 clamp it together, effectively preventing the plate from loosening during processing.

[0034] Please refer to Figure 1 , Figure 2 and Figure 5 A limiting mechanism 2 is fixedly connected to the left side of the fixed frame 13. The limiting mechanism 2 includes a limiting post 201 fixedly connected to the left side of the fixed frame 13. A scale placement groove 203 is opened on the top of the outer wall of the limiting post 201. The placement groove 203 crosses the length direction of the fixed frame 13. A fixing plate 202 is fixedly connected to the top of the fixed frame 13. A fixing post 206 is vertically fixedly connected to the bottom of the outer wall of the fixing plate 202. A rotating ring 205 is rotatably connected to the outer wall of the fixing post 206. The rotating ring 205 can rotate around the axis of the fixing post 206.

[0035] Please refer to Figure 1 , Figure 2 and Figure 4A limiting plate 208 is fixedly connected to the bottom of the outer wall of the rotating ring 205. A spring post 207 is fixedly connected to the right side of the limiting plate 208. The end of the spring post 207 away from the limiting plate 208 is fixedly connected to the bottom right side of the fixing plate 202. The spring post 207 is used to provide the torque for the limiting plate 208 to reset and press. A sliding groove 204 is opened on the top right side of the outer wall of the limiting post 201. The sliding groove 204 is an arc-shaped groove. The bottom of the outer wall of the rotating ring 205 slides in the inner wall of the sliding groove 204. One end of the limiting plate 208 extends to the top of the placement groove 203. Under the pulling force of the spring post 207, the limiting plate 208 can adjust the scale located in the placement groove 203. The fixing plate 202, the limiting post 201 and the support base 1 adopt an integral molding structure.

[0036] Working principle: Since the fixed frame 13 is fixedly connected to the top of the support base 1, the device is placed on the plate so that the top of the plate contacts the bottom of the fixed frame 13, and the other side of the plate contacts the top of the spring column 11. Since the spring column 11 is fixedly connected to the top of the lifting plate 10, the pressure of the plate on the spring column 11 will cause the lifting plate 10 to move downward. Since the rotating plate 9 is rotatably connected to the outer wall of the lifting plate 10, and the moving block 8 is rotatably connected to the bottom of the inner wall of the rotating plate 9, the downward movement of the lifting plate 10 will cause the rotating plate 9 to rotate. Since the square groove 3 is opened on the inner wall of the support base 1, and the moving block 8 is slidably connected to the inner wall of the square groove 3, the moving block 8 slides horizontally under the restriction of the square groove 3. Since the guide groove 4 is opened on the bottom right side of the inner wall of the square groove 3, and the sliding plate 6 is fixedly connected to the right side of the moving block 8, and the sliding plate 6 is slidably connected to the inner wall of the guide groove 4, the moving block 8 drives the sliding plate 6 to slide together. The sliding plate 6 slides under the restriction of the guide groove 4. One end of the support plate 1 is fixedly connected to the front side of the moving block 8, and the other end is fixedly connected to the front side of the inner wall of the square groove 3. The force of the moving block 8 will squeeze the spring column 11. Due to the action of the spring column 11 itself, the spring column 11 will push the moving block 8, so that the lifting plate 10 will abut against the bottom of the plate. Since the positioning hole 5 is opened on the top of the outer wall of the support base 1 and the positioning hole 7 is opened on the inner wall of the sliding plate 6, the positioning column 12 is slidably connected to the inner wall of the positioning hole 5 and the positioning column 12 is simultaneously slidably connected to the inner wall of the positioning hole 7. The positioning column 12 is inserted into the positioning hole 7 and the positioning hole 5 at the same time, further fixing the position of the moving block 8. Through the initial fixing of the spring column 11 and the further fixing of the positioning hole 5, the fixing frame 13 and the spring column 11 cooperate to clamp the plate, thereby playing the role of self-adaptive fixing of the plate thickness, improving versatility, reducing changeover costs, simplifying the operation process, improving processing efficiency, providing flexible protection, and avoiding damage to the plate.

[0037] Since the limiting post 201 in the limiting mechanism 2 is fixedly connected to the left side of the fixing frame 13, and the placement groove 203 is opened on the top of the outer wall of the limiting post 201, the size of the placement groove 203 matches the size of the scale. The scale is placed in the placement groove 203. Since the fixing plate 202 is fixedly connected to the top of the fixing frame 13, the fixing post 206 is fixedly connected to the bottom of the outer wall of the fixing plate 202, the rotating ring 205 is rotatably connected to the outer wall of the fixing post 206, the limiting plate 208 is fixedly connected to the bottom of the outer wall of the rotating ring 205, one end of the spring post 207 is fixedly connected to the right side of the limiting plate 208, and the other end is fixedly connected to the bottom right side of the fixing plate 202. The fixing plate 202 is a fixed... The column 206 provides fixation. Due to the action of the spring column 207, the spring column 207 will push the limiting plate 208 to drive the rotating ring 205 to rotate around the fixed column 206. Since the slide groove 204 is opened on the top right side of the outer wall of the limiting column 201, the bottom of the outer wall of the rotating ring 205 is slidably connected to the inner wall of the slide groove 204. The slide groove 204 provides rotation space for the limiting plate 208. The limiting plates 208 on the left and right sides of the fixed plate 202 flexibly limit the two sides of the scale, thereby playing the role of lateral limiting of the scale in the device, completely locking the size reference, avoiding positioning deviation, simplifying the operation process, improving adjustment efficiency, reducing component wear, and extending the device life.
