Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a machining tooling for easily deformable optical parts. Background Technology

[0002] In the field of optical manufacturing, the processing of easily deformable optical components such as thin-walled sleeves and lens frames has always been a challenge. These components typically have characteristics such as high precision requirements, relatively fragile materials, and poor structural rigidity.

[0003] During machining, specialized tooling is required for reliable positioning and clamping to prevent displacement or deformation of parts under cutting forces, vibrations, etc., ensuring machining accuracy. Currently, the most common clamping methods are mechanical rigid clamping, such as using chucks or fixtures for external or internal fixation. However, rigid clamping force is difficult to control, which can easily cause clamping deformation of thin-walled parts, or leave indentations or scratches on the part surface. Such deformation and damage may not be recoverable after machining, directly leading to the scrapping of parts and causing economic losses.

[0004] To address this, we propose a tooling solution for machining easily deformable optical components. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tooling for processing easily deformable optical parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tooling for processing easily deformable optical parts, including an assembly plate, a heat dissipation component fixedly connected to one side of the outer surface of the assembly plate, a housing fixedly connected to one end of the heat dissipation component, and a motor fixedly connected to the inner surface of the heat dissipation component; A shaft is fixedly connected to one side of the outer surface of the housing. Multiple sliding grooves that penetrate into the interior are evenly opened on the outer surface of the shaft. Inclined clamping rods slide inside each of the multiple sliding grooves. A rubber sleeve is fixedly fitted onto the outer surface of multiple inclined clamping rods; A pushing assembly is installed between the shaft and the motor, and a conical extrusion block is fixedly connected to the movable end of the pushing assembly.

[0007] Furthermore, the outer surface of the assembly plate is provided with a plurality of mounting holes that extend to the other side. The mounting holes facilitate the quick and stable installation of the entire tooling onto various processing equipment, thereby improving the tooling's versatility and installation efficiency.

[0008] Furthermore, the heat dissipation assembly includes an annular aluminum alloy radiator, which is fixedly connected to the mounting plate and the housing respectively. A thermal pad is fixedly connected to the inner surface of the annular aluminum alloy radiator, and the thermal pad is fixedly sleeved on the outer surface of the motor. The thermal pad is in close contact with the motor to quickly absorb heat, and the annular aluminum alloy radiator provides large-area and efficient heat dissipation, which can effectively prevent the motor from degrading or being damaged due to overheating.

[0009] Furthermore, the inclined surface of the inclined clamp is located on the inner side of the shaft and matches the conical extrusion block. This design of the inclined surface and the conical surface can convert the axial linear motion of the pushing component into the radial expansion motion of the inclined clamp.

[0010] Furthermore, the pushing assembly includes a screw, and the drive shaft of the motor is fixedly connected to the screw. The screw extends through to the inner side of the shaft. A nut is threaded onto the outer surface of the screw. One end of the nut is fixedly connected to a sleeve rod, which is sleeved on the outer surface of the screw and slidably connected to the shaft rod. The threaded transmission mechanism converts the rotational motion of the motor into the linear movement of the nut.

[0011] Furthermore, a round block is fixedly connected to one end of the sleeve rod, and the round block is fixedly connected to the conical extrusion block. The round block facilitates the fixed connection between the pushing component and the conical extrusion block.

[0012] The beneficial effects of this utility model are: In use, this utility model uses a motor-driven push assembly to move a conical extrusion block, causing multiple inclined clamping rods to slide radially along the groove of the shaft. The rubber sleeves flexibly contact the inner wall of the optical parts, achieving uniform clamping and effectively dispersing pressure, thus avoiding deformation, indentation, or scratches on the parts caused by traditional rigid clamping. At the same time, the heat dissipation assembly dissipates the heat generated by the generator in a timely manner, ensuring stable operation of the tooling. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4 As shown, this invention relates to a machining fixture for easily deformable optical components, including an assembly plate 1. Multiple mounting holes are evenly distributed on one side of the outer surface of the assembly plate 1, extending to the other side. The assembly plate 1 serves as the base and mounting interface of the entire fixture, and its core function is to achieve reliable connection and positioning between the fixture and external processing equipment (such as a machine tool table). The multiple evenly distributed mounting holes facilitate flexible and robust installation using standard parts such as bolts, ensuring the overall rigidity and stability of the fixture during the machining process.

[0018] A heat dissipation assembly is fixedly connected to one side of the outer surface of the assembly plate 1. A housing 3 is fixedly connected to one end of the heat dissipation assembly. A motor 6 is fixedly connected to the inner surface of the heat dissipation assembly. The heat dissipation assembly includes an annular aluminum alloy heat sink 2, which is fixedly connected to the assembly plate 1 and the housing 3 respectively. A thermal pad 7 is fixedly connected to the inner surface of the annular aluminum alloy heat sink 2, and the thermal pad 7 is fixedly sleeved on the outer surface of the motor 6. The annular aluminum alloy heat sink 2 has low density and high thermal conductivity, which can achieve lightweight and efficient heat dissipation, prevent the motor 6 from overheating, ensure the stable performance of the motor 6 and extend its service life. The motor 6 is a standard servo motor, which is electrically connected to the controller used by the external processing equipment, which is conducive to controlling the operation of the motor 6.

[0019] A shaft 5 is fixedly connected to one side of the outer surface of the housing 3. Multiple sliding grooves 14 are evenly opened on the outer surface of the shaft 5, extending into the interior. Inclined clamping rods 11 slide inside the multiple sliding grooves 14. A rubber sleeve 4 is fixedly fitted on the outer surface of the multiple inclined clamping rods 11. The rubber sleeve 4 is made of thin polyurethane rubber, which has the advantages of high strength, high elasticity, high wear resistance, tear resistance, and aging resistance, and is suitable for this application.

[0020] A pushing assembly is installed between the shaft 5 and the motor 6. The movable end of the pushing assembly is fixedly connected to a conical extrusion block 13. The inclined surface of the inclined clamping rod 11 is located on one side inside the shaft 5 and matches the conical extrusion block 13.

[0021] The driving assembly includes a screw 8, and the drive shaft of the motor 6 is fixedly connected to the screw 8. The screw 8 extends through the inner side of the shaft 5. A nut 9 is threaded onto the outer surface of the screw 8. A sleeve 10 is fixedly connected to one end of the nut 9. The sleeve 10 is fitted onto the outer surface of the screw 8 and is slidably connected to the shaft 5. A round block 12 is fixedly connected to one end of the sleeve 10. The round block 12 is fixedly connected to the conical extrusion block 13. The thread helix angle of the screw 8 is smaller than the friction angle, which gives the screw 8 a self-locking capability and can prevent it from shifting due to vibration or load.

[0022] Working principle: With the tooling in the released state, the shaft 5 is inserted into the interior of the optical sleeve (easily deformable part). At this time, the inclined clamping rod 11 retracts into the groove 14 of the shaft 5, and the rubber sleeve 4 has no contact or only slight contact with the inner wall of the sleeve.

[0023] Motor 6 is started, and its drive shaft rotates screw 8. Since screw 8 is threadedly connected to nut 9, nut 9 moves axially along screw 8. Nut 9 pushes sleeve 10 forward, which in turn pushes round block 12 and conical extrusion block 13 into shaft 5. After entering shaft 5, conical extrusion block 13 contacts the inclined surface of inclined clamping rod 11 and applies radial extrusion force. Due to the inclined surface design, inclined clamping rod 11 slides radially outward along groove 14. Multiple inclined clamping rods 11 expand outward synchronously, ensuring that the rubber sleeve 4, fixedly fitted to its outer surface, uniformly contacts the inner wall of the optical sleeve. Rubber sleeve 4 provides flexible clamping, disperses pressure, and prevents scratching or crushing of the easily deformable optical sleeve.

[0024] When the motor 6 continues to drive, the conical extrusion block 13 advances further, and the inclined clamping rod 11 expands to the predetermined position to achieve stable clamping.

[0025] During the operation of motor 6, the heat generated is conducted to the annular aluminum alloy radiator 2 through the heat-conducting pad 7, and the radiator dissipates the heat into the environment.

[0026] After processing, motor 6 reverses, driving screw 8 to rotate in the opposite direction, causing nut 9 to move sleeve 10 backward. Conical extrusion block 13 then retracts, and the extrusion force on inclined clamp 11 disappears. Under the elastic action of rubber sleeve 4, inclined clamp 11 contracts radially inward along slide groove 14, rubber sleeve 4 detaches from the inner wall of optical sleeve, and workpiece is safely released.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation.
