Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a tooling fixture for producing handle accessories for smart door locks. Background Technology

[0002] With the rapid development of the smart home industry, smart door locks, as core devices for home security and convenient access, are experiencing a continuous increase in market demand. The production precision and efficiency of their core component—the handle—have become key factors determining product quality. In the large-scale production of smart door lock handles, tooling fixtures are the core tools for achieving precise positioning and stable processing of the parts. They are widely used in key processes such as milling, drilling, and surface treatment of the handles. They can effectively fix the handle blanks or semi-finished products, avoiding problems such as dimensional deviations and surface scratches caused by workpiece displacement during processing. This directly affects the assembly precision, feel, and lifespan of the smart door lock handle, playing an irreplaceable role in ensuring the consistency of smart door lock products and improving the efficiency of production lines.

[0003] However, existing tooling fixtures for the production of smart door lock handle accessories have shortcomings in practical applications. On the one hand, in the loading and unloading of molds for handle accessory processing, traditional tooling fixtures mostly rely on manual operation to clamp or loosen the structure. This is not only cumbersome and labor-intensive, but also difficult to precisely control the clamping force—too loose and the workpiece will wobble during processing, while too tight and the workpiece will deform. At the same time, the mold removal process is time-consuming, disrupting the continuity of the production process and significantly reducing production efficiency. On the other hand, when the key components responsible for clamping and positioning in the tooling fixture malfunction due to long-term wear and deformation and need to be replaced, the existing structure often requires disassembling multiple fixing screws of the fixture and dismantling the entire frame to remove the damaged parts. The replacement process is time-consuming and complex, requiring the participation of professional technicians and causing long-term downtime of the production line, significantly increasing equipment maintenance costs and the risk of production delays. Therefore, a tooling fixture for the production of smart door lock handle accessories is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tooling fixture for the production of handle accessories for smart door locks, aiming to improve the problems of low mold loading and unloading efficiency and complex fixture replacement operation and high maintenance cost in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tooling fixture for producing handle accessories for smart door locks includes a support plate, a housing first fixedly connected to the top of the support plate, a base fixedly connected to the top of the housing first, multiple molds on the top of the base, a cylinder fixedly connected to the top of the support plate, a T-shaped block fixedly connected to the output end of the cylinder, multiple sliding grooves inside the support plate, multiple connecting rods slidably connected inside the T-shaped block, multiple connecting columns rotatably connected to the outer sides of the multiple connecting rods, baffles second fixedly connected to the outer sides of the multiple connecting columns, wedges slidably connected to the outer sides of the connecting columns, clamps slidably connected to both sides of the wedges, and a quick-release assembly on the top of the wedges. As a further description of the above technical solution: The quick-release assembly includes a baffle one, which is disposed on the top of the wedge block. A housing two is fixedly connected inside the baffle one. A button is slidably connected inside the housing two. Two clamping arms are rotatably connected inside the housing two. A spring is fixedly connected between the two clamping arms. A flexible plate is fixedly connected between the two clamping arms. A protrusion is fixedly connected to the top of the connecting post. As a further description of the above technical solution: The bottom of the T-shaped block is fixedly connected to multiple pulleys, which are slidably connected inside the corresponding grooves. As a further description of the above technical solution: The outer side of the connecting column is slidably connected to the inside of the base, and the top of the second baffle abuts against the bottom of the wedge; As a further description of the above technical solution: The second baffle is slidably connected between the two clamping openings, and the outer side of the clamping opening abuts against the outer side of the mold. As a further description of the above technical solution: The base has multiple grooves on its top, and the mold is slidably connected inside the grooves. As a further description of the above technical solution: The bottom of the baffle abuts against the top of the wedge, and the bottom of the button abuts against the top of the flexible plate; As a further description of the above technical solution: The spring is located directly above the protrusion, the second outer casing is located directly above the connecting post, and the protrusion is located between the two clamping arms.

[0006] This utility model has the following beneficial effects: 1. In this utility model, when removing the mold, the cylinder is activated to push the T-shaped block. The T-shaped block slides inside the slide groove via the pulley at the bottom. At the same time, the connecting rod slides inside the T-shaped block to the highest point and drives the connecting column to move upward. The connecting column pushes the wedge block upward through the second baffle. The wedge block pulls back the clamping jaws to close inward, thus releasing the mold and removing it. When clamping the mold, the cylinder retracts and drives the T-shaped block to slide via the pulley, which drives the connecting rod to slide the connecting column downward. The connecting column is fixed to the clamping arm by the protrusion at the top, thereby pulling the wedge block downward and squeezing the clamping jaws on both sides, thus fixing the mold.

[0007] 2. In this utility model, when the wedge block is worn or has a structural fault and needs to be replaced, press the button to push the soft plate, the clamping arm is opened, and the spring is stretched at the same time, so that the wedge block is separated from the connecting post. After the worn wedge block is removed and replaced, the protrusion is re-engaged into the clamping arm. Release the button, the spring returns to its original position and locks the wedge block, thus allowing the wedge block to be replaced. Attached Figure Description

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.

[0011] Reference Figure 1 - Figure 6 This utility model provides an embodiment of a tooling fixture for producing handle accessories for smart door locks, comprising a support plate 1, a housing 4 fixedly connected to the top of the support plate 1, a base 3 fixedly connected to the top of the housing 4, multiple molds 6 on the top of the base 3, a cylinder 2 fixedly connected to the top of the support plate 1, a T-shaped block 11 fixedly connected to the output end of the cylinder 2, multiple sliding grooves 5 inside the support plate 1, multiple connecting rods 13 slidably connected inside the T-shaped block 11, multiple connecting posts 14 rotatably connected to the outer sides of the multiple connecting rods 13, baffles 15 fixedly connected to the outer sides of the multiple connecting posts 14, wedges 9 slidably connected to the outer sides of the connecting posts 14, clamps 19 slidably connected to both sides of the wedges 9, and quick-release components on the top of the wedges 9. Multiple pulleys 10 are fixedly connected to the bottom of the T-shaped block 11, and the pulleys 10 are slidably connected inside the corresponding sliding grooves 5. The outer sides of the connecting posts 14 are slidably connected inside the base 3, and the top of the baffles 15 abuts against the bottom of the wedges 9. The second baffle 15 is slidably connected between the two clamps 19, and the outer side of the clamps 19 abuts against the outer side of the mold 6. The top of the base 3 has multiple grooves, and the mold 6 is slidably connected inside the grooves.

[0012] Support plate 1 provides mounting reference and structural support for all parts, ensuring the overall stability of the fixture. Outer shell 4 provides space for the internal structure and protects it from external interference. Base 3 serves as a support platform for mold 6, the part processed by the device. Cylinder 2 outputs T-block 11. When cylinder 2 pushes T-block 11, it slides inside the slide groove 5 via pulley 10 at the bottom. Simultaneously, connecting rod 13 slides inside T-block 11 to its highest point, driving connecting column 14 upward. Connecting column 14 pushes wedge 9 upward via baffle 15. Wedge 9 pulls back clamp 19, closing inward to release mold 6 and remove it. When cylinder 2 retracts, it drives T-block 11 to slide via pulley 10, driving connecting rod 13 to slide connecting column 14 downward. 4. The top protrusion 18 is fixed to the clamping arm 8, thereby pulling the wedge 9 downward and squeezing the clamping openings 19 on both sides, thus fixing the mold 6. The T-shaped block 11 is used to drive the connecting rod 13 to slide inside it. The pulley 10 is used to make the T-shaped block 11 slide smoothly inside the slide groove 5. The slide groove 5 is used to limit the movement trajectory of the pulley 10 and prevent the T-shaped block 11 from deviating. The connecting rod 13 is used to transmit the translational movement of the T-shaped block 11 to the connecting column 14. The stop block is used to limit the sliding range of the connecting rod 13 in the T-shaped block 11 and prevent it from falling off. The connecting column 14 is used to drive the wedge 9 to move up and down. The second baffle 15 is used to push the wedge 9 to move upward. The wedge 9 is used to squeeze and release the clamping openings 19 by moving up and down, so that the clamping openings 19 can fix and disassemble the mold 6. The clamping openings 19 are used to act on the mold 6.

[0013] Reference Figure 1 - Figure 7 The quick-release assembly includes a first baffle 7, which is positioned on top of the wedge 9. A second housing 12 is fixedly connected inside the first baffle 7. A button 16 is slidably connected inside the second housing 12. Two clamping arms 8 are rotatably connected inside the second housing 12. A spring 17 is fixedly connected between the two clamping arms 8. A flexible plate 20 is fixedly connected between the two clamping arms 8. A protrusion 18 is fixedly connected to the top of the connecting post 14. The bottom of the first baffle 7 abuts against the top of the wedge 9, and the bottom of the button 16 abuts against the top of the flexible plate 20. The spring 17 is located directly above the protrusion 18, the second housing 12 is located directly above the connecting post 14, and the protrusion 18 is located between the two clamping arms 8.

[0014] The baffle 7 is used to push the wedge 9 downwards, and the button 16 is used to squeeze the flexible plate 20, which drives the clamping arm 8 to clamp the protrusion 18 under the action of the spring 17 and lock it. Pressing the button 16 pushes the flexible plate 20, the clamping arm 8 is opened, and the spring 17 is stretched, so that the wedge 9 is replaced and the protrusion 18 is re-clamped into the clamping arm 8. Releasing the button 16 resets the spring 17 to achieve locking. The clamping arm 8 is used to clamp the protrusion 18, and the spring 17 is used to reset the two clamping arms 8. The flexible plate 20 is used to prevent the button 16 from directly and rigidly squeezing the clamping arm 8, which would cause it to wear. At the same time, it evenly transmits the pressing force of the button 16 to the two clamping arms 8 to ensure that they open synchronously, thereby releasing and locking the protrusion 18, completing the disassembly and replacement. The protrusion 18 is used to fix and separate the connecting post 14 from the quick-release assembly by clamping and separating with the clamping arm 8, so as to complete the disassembly and replacement.

[0015] Working principle: When removing mold 6, cylinder 2 is activated to push T-block 11. T-block 11 slides away from cylinder 2 inside the slide groove 5 via pulley 10 at the bottom. At the same time, connecting rod 13 slides to the highest point inside T-block 11, driving connecting column 14 to move upward. Connecting column 14 pushes wedge 9 upward through baffle 15. Wedge 9 pulls back clamping jaws 19 to close inward, releasing mold 6 and removing it. When mold 6 is clamped, cylinder 2 retracts, causing T-block 11 to slide towards cylinder 2 via pulley 10, driving connecting rod 13 to... The connecting post 14 slides downward and is fixed to the clamping arm 8 by the protrusion 18 on the top of the connecting post 14, thereby pulling the wedge 9 downward and squeezing the clamping openings 19 on both sides, thus fixing the mold 6. When the wedge 9 is worn or has a structural failure and needs to be replaced, press the button 16 to push the soft plate 20, the clamping arm 8 is opened, and the spring 17 is stretched, so that the wedge 9 is separated from the connecting post 14. After the worn wedge 9 is removed and replaced, the protrusion 18 re-engages into the clamping arm 8. Release the button 16, and the spring 17 returns to its original position to lock, thus allowing the wedge 9 to be replaced.
