Description
Technical Field
[0001] This utility model relates to the technical field of drilling and positioning devices, and in particular to an auxiliary positioning device for drilling molds. Background Technology
[0002] In mold processing, the drilling accuracy directly determines the mold assembly accuracy and service life. This is especially true for molds that require drilling on both sides, where positioning stability and processing efficiency are even more critical.
[0003] However, most existing clamping and positioning structures can only achieve clamping in one direction. When drilling molds, the top surface is easily affected by cutting forces, resulting in the top surface lifting and the side offset, which leads to excessive hole position deviation. Furthermore, after one side of the mold is processed, it is necessary to manually flip the mold and reposition it, which not only poses operational safety hazards, but also easily produces positioning errors during secondary clamping, making it difficult to guarantee the coaxiality of the front and back hole positions. In view of this, this application proposes an auxiliary positioning device for drilling molds. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary positioning device for mold punching.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary positioning device for die punching includes a body with two symmetrically slidably connected support platforms on its top surface. A moving mechanism is installed inside the body, driving the two support platforms to slide towards each other. Two side plates are symmetrically installed on the top surface of the body. A first motor is fixedly installed on the outer side of each side plate. A first electric push rod is installed at one end of the output shaft of each first motor, and a first clamping plate is installed at the other end of each first electric push rod. Two rotating frames are symmetrically rotatably connected inside the body. An opening and closing mechanism is installed inside the body, driving the two rotating frames to rotate symmetrically. A positioning auxiliary component is installed on each rotating frame, providing auxiliary positioning for the top and side surfaces of the die. A controller is installed on the outer side of the body.
[0006] Preferably, each of the positioning auxiliary components includes a second electric push rod, and each second electric push rod is fixedly installed on the outside of the rotating frame. A second clamping plate is installed at the other end of each second electric push rod. Multiple spring telescopic rods are installed on the top surface of each rotating frame, and a pressure plate is installed at the bottom end of the multiple spring telescopic rods located on the same side.
[0007] Preferably, the opening and closing mechanism includes two rotating shafts, which are symmetrically rotatably connected to the side wall of the machine body. One end of each rotating frame is fixedly installed on the outside of the corresponding rotating shaft. A gear is installed on the outside of each rotating shaft, and the two gears mesh with each other. A second motor is fixedly installed on the outside of the machine body, and the output shaft of the second motor is coaxially connected to one of the rotating shafts.
[0008] Preferably, the moving mechanism includes a double-ended screw, which is rotatably connected to the side wall of the machine body. Two threaded sleeves are symmetrically threaded on the double-ended screw, and the top of each threaded sleeve is fixedly connected to the bottom surface of the corresponding support platform. A third motor is fixedly installed on the outside of the machine body, and the output shaft of the third motor is coaxially connected to the double-ended screw.
[0009] Preferably, a guide rod is fixedly installed on the side wall of the machine body, and each threaded sleeve is slidably connected to the guide rod. Multiple guide rails are symmetrically installed on the top surface of the machine body, and each support platform is slidably connected to the corresponding guide rail.
[0010] Preferably, each of the support platforms has a movable groove on its top surface, and each movable groove corresponds to the position of the side plate. The second motor, the third motor and the first motor are all conical rotor motors.
[0011] This utility model has the following beneficial effects: 1. This utility model achieves automatic mold flipping and basic clamping and positioning through devices such as side plates, a first motor, a first electric push rod, a first clamping plate, a support platform, a machine body, and a moving mechanism. The support platform provides bottom support for the mold, and the first electric push rod drives the first clamping plate to clamp the mold from both sides. After one side is processed, the moving mechanism drives the support platform to separate and expose the internal cavity of the machine body. The first motor drives the first electric push rod to rotate in the same direction to complete the flipping. No manual operation is required, avoiding safety hazards, reducing secondary clamping errors, and ensuring the coaxiality of the front and back holes.
[0012] 2. This utility model achieves multi-directional stable positioning of the mold through opening and closing mechanism, positioning auxiliary components and other devices, avoiding displacement during drilling. In the opening and closing mechanism, the second motor drives the rotating shaft, which drives the rotating frame to close symmetrically through gear transmission. The second electric push rod of the positioning auxiliary component pushes the second clamping plate to clamp the other two sides of the mold. At the same time, the spring telescopic rod drives the pressure plate to press the top surface, forming a two-way side-top positioning, resisting the influence of cutting force, preventing the top surface from tilting and the side from shifting, and greatly improving the hole position accuracy.

[0015] 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.
[0016] This utility model provides a technical solution: such as Figure 1-5 As shown, an auxiliary positioning device for die punching includes a body 1. Two support platforms 3 are symmetrically slidably connected to the top surface of the body 1. A moving mechanism is installed inside the body 1, and the moving mechanism drives the two support platforms 3 to slide towards each other. Two side plates 5 are symmetrically installed on the top surface of the body 1. A first motor 6 is fixedly installed on the outer side of each side plate 5. A first electric push rod 7 is installed at one end of the output shaft of each first motor 6. A first clamping plate 8 is installed at the other end of each first electric push rod 7. Two rotating frames 4 are symmetrically rotatably connected inside the body 1. An opening and closing mechanism is installed inside the body 1, and the opening and closing mechanism drives the two rotating frames 4 to rotate symmetrically. A positioning auxiliary component is installed on each rotating frame 4, and the positioning auxiliary component provides auxiliary positioning for the top surface and side surface of the die. A controller 2 is installed on the outer side of the body 1. It should be noted that the machine body 1 has an internal cavity for mold flipping, and the support platform 3 is used to close the cavity and provide bottom support for the mold. The first electric push rods 7 on both sides are synchronously controlled to extend and retract by the controller 2 to firmly clamp the mold. After the support platform 3 is opened to expose the cavity, the two first electric push rods 7 can be driven by the two first motors 6 to rotate in the same direction, thereby flipping the mold. In order to reduce the friction between the support platform 3 and the mold, several rotating balls can be installed on the top surface of each support platform 3 to reduce friction damage to the mold.
[0017] Furthermore, each positioning auxiliary component includes a second electric push rod 13, and each second electric push rod 13 is fixedly installed on the outside of the rotating frame 4. The other end of each second electric push rod 13 is equipped with a second clamping plate 14. The top surface of each rotating frame 4 is equipped with multiple spring telescopic rods 11, and the bottom ends of the multiple spring telescopic rods 11 located on the same side are all equipped with a pressure plate 12. The second clamping plate 14 and the second electric push rod 13 are used to clamp the other two sides of the mold, and the pressure plate 12 applies downward pressure to the mold to ensure that the mold does not shift, thereby ensuring the accuracy of the mold when drilling.
[0018] Furthermore, the opening and closing mechanism includes two rotating shafts 15, which are symmetrically rotatably connected to the side wall of the body 1. One end of each rotating frame 4 is fixedly installed on the outside of the corresponding rotating shaft 15. A gear 16 is installed on the outside of each rotating shaft 15, and the two gears 16 mesh with each other. A second motor 17 is fixedly installed on the outside of the body 1, and the output shaft of the second motor 17 is coaxially connected to one of the rotating shafts 15. Two gears 16 cause two rotating shafts 15 to rotate in opposite directions, thereby driving two rotating frames 4 to open and close. Before the mold flips, the rotating frames 4 are controlled to unfold, so that the auxiliary positioning components are moved away from the mold. Before the mold is polished, the rotating frames 4 are controlled to reset, and the mold is further clamped and positioned by the auxiliary positioning components.
[0019] Furthermore, the moving mechanism includes a double-ended screw 19, which is rotatably connected to the side wall of the machine body 1. Two threaded sleeves 21 are symmetrically threaded on the double-ended screw 19, and the top of each threaded sleeve 21 is fixedly connected to the bottom surface of the corresponding support platform 3. A third motor 18 is fixedly installed on the outside of the machine body 1, and the output shaft of the third motor 18 is coaxially connected to the double-ended screw 19.
[0020] Furthermore, guide rods 20 are fixedly installed on the side wall of the machine body 1, and each threaded sleeve 21 is slidably connected to the guide rod 20. Multiple guide rails 10 are symmetrically installed on the top surface of the machine body 1, and each support platform 3 is slidably connected to the corresponding guide rail 10. The threaded sleeve 21 is guided and limited by the guide rod 20, while the bearing platform 3 is guided and limited by the guide rail 10.
[0021] Furthermore, each support platform 3 has a movable groove 9 on its top surface, and each movable groove 9 corresponds to the position of the side plate 5 to prevent the side plate 5 from affecting the normal sliding of the support platform 3. The second motor 17, the third motor 18 and the first motor 6 are all conical rotor motors, and their output shafts can automatically lock after power failure, which facilitates the limiting of the components installed on their output shafts.
[0022] This utility model provides an auxiliary positioning device for mold drilling, the specific working principle of which is as follows: First, the mold to be processed is placed on the top surface of the support platform 3. Then, the second motor 17 is started by the controller 2. Its output shaft drives the rotating shaft 15 to rotate. Through the transmission of two meshing gears 16, the other rotating shaft 15 rotates in the opposite direction, thereby driving the two rotating frames 4 to close symmetrically. Then, the second electric push rod 13 extends and pushes the second clamping plate 14 to clamp the two sides of the mold. At the same time, the spring telescopic rod 11 drives the pressure plate 12 to press the top surface of the mold, forming a side-top bidirectional positioning. Furthermore, the first electric push rod 7 synchronously extends and clamps the mold, further pressing the mold to ensure drilling accuracy. After the top surface of the mold is processed, the rotating frame 4 can be unfolded, and the third motor 18 can be started to drive the double-headed screw 19 to rotate. Under the guidance and limit of the guide rod 20, the threaded sleeve 21 drives the two bearing platforms 3 to slide back and forth along the guide rail 10, causing the bearing platforms 3 to separate and expose the cavity. Then, the two first motors 6 drive the two first electric push rods 7 to rotate in the same direction to achieve flipping. After flipping, the support platform 3 resets and closes, and the rotating frame 4 closes and repositions to ensure drilling accuracy.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
