Description

Technical Field

[0001] This invention relates to the technical field of clamping equipment for casting spindle clamp body molds, specifically a clamping assembly for casting spindle clamp body molds. Background Technology

[0002] A spindle clamp is a device on a machine tool spindle used to hold tools or workpieces. Its core function is to ensure stable and precise positioning of the clamping components during high-speed rotation and to transmit torque. There are various types of spindle clamps, commonly including spring collets, ER collets, and special-purpose fixtures. The design of spindle clamps must meet requirements for high rotational accuracy, resistance to centrifugal force, and thermal stability.

[0003] An existing clamping assembly for casting a spindle clamp body mold typically requires manual adjustment of components such as nuts when clamping different types of molds. It cannot be quickly adjusted and clamped according to the mold size. Manual adjustment of the clamping components wastes a lot of manpower and time, and reduces the machine's working efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping assembly for casting a spindle clamp body mold, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a clamping assembly for casting a spindle clamp body mold, comprising a clamping base, a bracket fixedly connected to the surface of the clamping base, a lower mold disposed above the clamping base, an upper mold mounted above the lower mold, a support fixedly connected to the bottom of the clamping base, a lower mold clamping device disposed above the clamping base, an upper mold fixing device disposed above the clamping base, and a fixing support device disposed above the clamping base.

[0007] Furthermore, the elongated plate is located below the clamping base, the end of the shock-absorbing block away from the clamping base is fixedly connected to the bottom of the support platform, the support platform is located below the lower mold clamping device, and the threaded rod passes through the sliding plate and extends to the outer end of the sliding plate.

[0008] Furthermore, the end of the sliding plate away from the threaded rod is fixedly connected to the bottom of the pulley, the end of the limiting telescopic rod away from the slide groove is fixedly connected to the surface of the pulley, the sliding rod passes through the support plate and extends to the surface of the spring plate, and the end of the sliding rod away from the clamping flexible plate is fixedly connected to the surface of the spring plate.

[0009] Furthermore, the upper mold fixing device includes a telescopic support rod, the end of which is fixedly connected to the top of the clamping base. An extrusion plate is fixedly connected to the end of the telescopic support rod away from the clamping base. A sloped pressure plate is fixedly connected to the bottom of the extrusion plate. A limit rod is fixedly connected to the surface of the sloped pressure plate. A telescopic round rod is fixedly connected to the top of the support plate. An elastic rod is fixedly connected to the top of the support plate. A force-applying rod is fixedly connected to the end of the telescopic round rod away from the support plate. A fixed pressure plate is fixedly connected to the end of the force-applying rod away from the telescopic round rod. An inclined plate is hinged to the end of the fixed pressure plate. A fixed extrusion plate is hinged to the end of the inclined plate away from the fixed pressure plate.

[0010] Furthermore, the telescopic support rod is located close to the clamping base and the extrusion plate, the end of the limiting rod away from the inclined pressure plate is adapted to the surface of the fixed pressure plate, the top of the fixed pressure plate is in contact with the bottom of the inclined pressure plate, and the end of the elastic rod away from the support plate is fixedly connected to the bottom of the force-applying rod.

[0011] Furthermore, the fixed support device includes a one-way electric actuator, the surface of which is fixedly connected to the inner wall of the bracket, a lifting pull plate fixedly connected to the output end of the one-way electric actuator, a connecting thin rod fixedly connected to the surface of the extrusion plate, a telescopic bending plate fixedly connected to the output end of the one-way electric actuator, a circular telescopic rod fixedly connected to the surface of the slider, a movable locking block fixedly connected to the surface of the slider, a hinge plate hinged to the end of the movable locking block away from the slider, a lifting support plate hinged to the end of the hinge plate away from the movable locking block, a slot provided on the inner wall of the clamping base, and a tension rod fixedly connected to the bottom of the lifting support plate.

[0012] Furthermore, the end of the telescopic bending plate away from the unidirectional electric actuator is fixedly connected to the surface of the slider, the end of the circular telescopic rod away from the slider is fixedly connected to the surface of the support platform, the surface of the movable block is adapted to the inner wall surface of the slot, the end of the tension rod away from the lifting support plate is fixedly connected to the bottom of the inner wall of the slot, and the lifting support plate is located below the support platform.

[0013] The present invention has the following beneficial effects: When the lower mold clamping device and upper mold fixing device of this invention are placed above the support platform for casting, the pressure will squeeze the support platform downwards. The downward pressure of the support platform on the flexible rod will cause the elongated plate to move downwards, stabilizing the position of the mold as it moves downwards. At the same time, the downward movement of the support platform squeezes the shock-absorbing block, which will have a shock-absorbing effect, making the mold more stable during the casting process. When the motor is turned on, the output end will drive the threaded rod to rotate, causing the sliding plates to move closer or further apart on the surface of the threaded rod. When the sliding plates move, they will drive the pulley to move inside the slide groove. The limiting telescopic rod stabilizes the position of the pulley as it moves. At the same time, the telescopic rod will move the sliders closer or further apart. When the sliders move closer together, the support plate will drive the sliding rod to push the clamping soft plate closer together, so that the clamping soft plate clamps the mold. This makes the mold more stable during the casting process and avoids inaccurate casting position caused by mold position deviation, thus avoiding material waste. At the same time, when the clamping soft plate clamps the mold, it will squeeze the sliding rod to slide inside the support plate to avoid mold deformation due to excessive compression. The spring plate makes the sliding rod stable when it moves and also plays a role in resetting the sliding rod.

[0014] When the support plates of this invention approach each other, they drive the force-applying rods to move back and forth via the telescopic round rods and elastic rods. When the mold is casting, the force-applying rods approach each other, pushing the fixed pressure plate to move. Due to the pressure of the inclined pressure plate, the fixed pressure plate moves downward, reinforcing the upper mold fixing device and preventing mold misalignment caused by vibration during casting. When the fixed pressure plate moves backward, the limiting rod limits its movement, preventing it from detaching from the inclined pressure plate and affecting the normal pressing of the mold. When the fixed pressure plates approach each other, they press the inclined plate, causing the fixed extrusion plates to approach each other, providing secondary fixation to the upper mold fixing device and making the mold more stable during casting. When the force-applying rods move the fixed pressure plates away from each other, the elastic rods, due to their elasticity, drive the force-applying rods and fixed pressure plates upward, causing the fixed pressure plates to move the inclined plate and fixed extrusion plates upward, detaching the fixed extrusion plates from the upper mold fixing device for easy mold replacement.

[0015] When the sliders of this invention approach each other, they cause the moving blocks to approach each other as well. As the moving blocks move forward, they fall into the slots, thus securing the mold and ensuring a more stable clamping operation, preventing slippage and ensuring a better casting result. When the moving blocks approach each other, they cause the lifting support plate to move upwards via the pressing hinge plate, bringing its top into contact with the bottom of the support platform. This provides support to the support platform and prevents mold deformation caused by the increased weight of the mold pressing down on the support platform during casting. The tension rod ensures the lifting support plate remains stable during movement. After casting is complete, the one-way electric push rod activates, and its output end drives the pressing plate and slider upwards via the lifting pull plate and telescopic bending plate, causing the slider to disengage the moving blocks from the slots. This allows the clamping components to quickly disengage from the mold. As the slider moves upwards, it moves the support platform along with it via the circular telescopic rod. The telescopic support rod further stabilizes the pressing plate as it moves up and down.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A long plate 21 is fixedly connected to the bottom of the flexible rod 20, and a shock-absorbing block 22 is fixedly connected to the top of the clamping base 1. The shock-absorbing block 22 provides shock absorption. A support platform 23 is fixedly connected to the end of the flexible rod 20 away from the long plate 21. When the support platform 23 presses the flexible rod 20 downward, it causes the long plate 21 to move downward, ensuring the mold is stable when it moves downward. A motor 24 is fixedly connected to the inner wall of the support frame 5. When the motor 24 is turned on... When the output end rotates the threaded rod 25, the sliding plates 32 move closer or further apart on the surface of the threaded rod 25. The output end of the motor 24 is fixedly connected to the threaded rod 25. The inner wall of the clamping base 1 is provided with a sliding groove 26. The surface of the threaded rod 25 is threadedly connected to the sliding plate 32. When the sliding plate 32 moves, it drives the pulley 33 to move inside the sliding groove 26. The inner wall of the sliding groove 26 is slidably connected to the pulley 33. When the pulley 33 moves, it drives the slider 27 to move closer or further apart through the telescopic rod 34.

A telescopic rod 34 is fixedly connected to the top of the pulley 33. A slider 27 is fixedly connected to the end of the telescopic rod 34 away from the pulley 33. When the sliders 27 approach each other, they will drive the slide rod 30 to push the clamping soft plate 31 to approach each other through the support plate 28, so that the clamping soft plate 31 clamps the mold. A support plate 28 is fixedly connected to the end of the slider 27 away from the telescopic rod 34. A slide rod 30 is slidably connected to the inner wall of the support plate 28. The clamping soft plate 31 is fixedly connected to the end of the slide rod 30. When the clamping soft plate 31 clamps the mold, it will slide inside the support plate 28 by squeezing the slide rod 30. A spring plate 29 is fixedly connected to the surface of the support plate 28. The spring plate 29 keeps the position of the slide rod 30 stable when it moves, and at the same time, it resets the slide rod 30.

[0023] The elongated plate 21 is located below the clamping base 1. The end of the shock-absorbing block 22 away from the clamping base 1 is fixedly connected to the bottom of the support platform 23. The support platform 23 is located below the lower mold clamping device 6. The threaded rod 25 passes through the sliding plate 32 and extends to the outer end of the sliding plate 32.

[0024] The end of the sliding plate 32 away from the threaded rod 25 is fixedly connected to the bottom of the pulley 33, the end of the limiting telescopic rod 35 away from the slide groove 26 is fixedly connected to the surface of the pulley 33, the sliding rod 30 passes through the support plate 28 and extends to the surface of the spring plate 29, and the end of the sliding rod 30 away from the clamping soft plate 31 is fixedly connected to the surface of the spring plate 29.

[0025] The upper mold fixing device 7 includes a telescopic support rod 40. The end of the telescopic support rod 40 is fixedly connected to the top of the clamping base 1. An extrusion plate 41 is fixedly connected to the end of the telescopic support rod 40 away from the clamping base 1. An inclined pressure plate 42 is fixedly connected to the bottom of the extrusion plate 41. A limit rod 43 is fixedly connected to the surface of the inclined pressure plate 42. The limit rod 43 will limit the fixed pressure plate 47. A telescopic round rod 44 is fixedly connected to the top of the support plate 28. The telescopic round rod 44 and the elastic rod 45 drive the force application rod 46 to move back and forth. An elastic rod 45 is fixedly connected to the top of the support plate 28. The end of the telescopic round rod 44 away from the support plate 28... A force-applying rod 46 is fixedly connected to the upper mold fixing device 7. When the force-applying rods 46 move closer together, they will push the fixed pressure plate 47 to move. The end of the force-applying rod 46 away from the telescopic round rod 44 is fixedly connected to the fixed pressure plate 47. The fixed pressure plate 47 will move downwards when it moves due to the squeezing of the inclined pressure plate 42, so that the fixed pressure plate 47 can perform a reinforcing squeezing operation on the upper mold fixing device 7. The end of the fixed pressure plate 47 is hingedly connected to the inclined plate 48. The inclined plate 48 drives the fixed extrusion plate 49 to move closer together, so that the fixed extrusion plate 49 can perform a secondary fixing operation on the upper mold fixing device 7. The end of the inclined plate 48 away from the fixed pressure plate 47 is hingedly connected to the fixed extrusion plate 49.

[0026] The telescopic support rod 40 is located close to the clamping base 1 and the pressing plate 41. The end of the limiting rod 43 away from the inclined pressure plate 42 is adapted to the surface of the fixed pressure plate 47. The top of the fixed pressure plate 47 is in contact with the bottom of the inclined pressure plate 42. The end of the elastic rod 45 away from the support plate 28 is fixedly connected to the bottom of the force application rod 46.

[0027] The fixed support device 8 includes a one-way electric actuator 50. When the one-way electric actuator 50 is opened, its output end drives the pressing plate 41 and the slider 27 upward via the lifting plate 51 and the telescopic bending plate 53, respectively, causing the slider 27 to disengage the moving block 55 from the slot 59. The surface of the one-way electric actuator 50 is fixedly connected to the inner wall of the bracket 2. The lifting plate 51 is fixedly connected to the output end of the one-way electric actuator 50. A connecting thin rod 52 is fixedly connected to the surface of the pressing plate 41. The telescopic bending plate 53 is fixedly connected to the output end of the one-way electric actuator 50. A circular telescopic rod 54 is fixedly connected to the surface of the slider 27. A moving block 55 is fixedly connected to the surface of the slider 27. When the movable block 55 moves forward, it falls into the slot 59, thus locking the position. The end of the movable block 55 away from the slider 27 is hinged to a hinge plate 56. The hinge plate 56 drives the lifting support plate 57 to move upward, so that the top of the lifting support plate 57 contacts the bottom of the support platform 23, thus supporting the support platform 23. The end of the hinge plate 56 away from the movable block 55 is hinged to the lifting support plate 57. The inner wall of the clamping base 1 is provided with a slot 59. The bottom of the lifting support plate 57 is fixedly connected to a tension rod 58, which makes the position of the lifting support plate 57 more stable when it moves.

[0028] The end of the telescopic bending plate 53 away from the unidirectional electric push rod 50 is fixedly connected to the surface of the slider 27. The end of the circular telescopic rod 54 away from the slider 27 is fixedly connected to the surface of the support platform 23. The surface of the movable block 55 is adapted to the inner wall surface of the slot 59. The end of the tension rod 58 away from the lifting support plate 57 is fixedly connected to the bottom of the inner wall of the slot 59. The lifting support plate 57 is located below the support platform 23.

[0029] During use, when the lower mold clamping device 6 and the upper mold fixing device 7 are placed above the support platform 23 for casting, the pressure will squeeze the support platform 23 downwards. The downward pressure of the support platform 23 on the flexible rod 20 will cause the elongated plate 21 to move downwards, stabilizing the position of the mold as it moves downwards. At the same time, the downward movement of the support platform 23 squeezes the shock-absorbing block 22, which will have a shock-absorbing effect, making the mold more stable during the casting process. When the motor 24 is turned on, the output end will drive the threaded rod 25 to rotate, causing the sliding plates 32 to move closer or further apart on the surface of the threaded rod 25. When the sliding plates 32 move, they will drive the pulley 33 to move inside the slide groove 26. The limiting telescopic rod 35 stabilizes the position of the pulley 33 as it moves. When the pulley 33 moves, it will drive the telescopic rod 34 to move the pulley 33. The sliders 27 move closer or further apart. When the sliders 27 move closer together, the support plate 28 drives the sliding rod 30 to push the clamping soft plate 31 closer together, so that the clamping soft plate 31 clamps the mold, making the mold more stable during the casting process and avoiding inaccurate casting position caused by mold position deviation, thus avoiding material waste. At the same time, when the clamping soft plate 31 clamps the mold, it squeezes the sliding rod 30 to slide inside the support plate 28, avoiding mold deformation due to excessive compression. The spring plate 29 stabilizes the position of the sliding rod 30 when it moves and also resets the sliding rod 30. When the support plates 28 move closer together, the telescopic round rod 44 and the elastic rod 45 drive the force application rod 46 to move forward. When the mold is casting, the force-applying rods 46 move closer together, pushing the fixed pressure plate 47 to move. Due to the pressure from the inclined pressure plate 42, the fixed pressure plate 47 moves downwards, reinforcing the upper mold fixing device 7 and preventing mold misalignment caused by vibration during casting. When the fixed pressure plate 47 moves backward, the limiting rod 43 limits its movement, preventing it from detaching from the inclined pressure plate 42 and affecting normal mold pressing. When the fixed pressure plates 47 move closer together, they press the inclined plate 48, causing the fixed pressing plate 49 to move closer together, providing secondary fixation to the upper mold fixing device 7, ensuring proper mold stability during casting. During casting, the machine is more stable. When the force-applying rod 46 moves the fixed pressure plate 47 away from each other, the elastic rod 45 will move the force-applying rod 46 and the fixed pressure plate 47 upward due to the elastic force. This causes the fixed pressure plate 47 to move the inclined plate 48 and the fixed extrusion plate 49 upward, disengaging the fixed extrusion plate 49 from the upper mold fixing device 7, facilitating mold replacement. When the sliders 27 approach each other, they will cause the moving blocks 55 to approach each other. When the moving blocks 55 move forward, they will fall into the slot 59, thus playing a locking role. This makes the machine more secure when clamping the mold, preventing slippage and other problems that could affect the casting effect. When the moving blocks 55 approach each other, they will move the lifting support plate 57 upward through the extrusion hinge plate 56.The top of the lifting support plate 57 contacts the bottom of the support platform 23, providing support for the support platform 23 and preventing mold deformation caused by the increased weight of the mold pressing down on the support platform 23 during casting. The tension rod 58 makes the position of the lifting support plate 57 more stable when it moves. After casting is completed, the one-way electric push rod 50 is activated, and the output end drives the extrusion plate 41 and the slider 27 upward through the lifting pull plate 51 and the telescopic bending plate 53, respectively. This causes the slider 27 to disengage the moving block 55 from the slot 59, allowing the clamping components to quickly disengage from the mold. When the slider 27 moves upward, it drives the support platform 23 to move together through the circular telescopic rod 54. The telescopic support rod 40 makes the position of the extrusion plate 41 more stable when it moves up and down.
