Description

Technical Field

[0001] This utility model relates to the field of positioning technology for irregularly shaped castings, specifically a positioning fixture for irregularly shaped castings. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is processed by subsequent means such as grinding to obtain an object with a certain shape, size and performance. Irregular castings refer to castings with irregular shapes.

[0003] For example, patent document CN 221953121 U discloses a positioning fixture for aluminum alloy die castings, including a worktable with a positioning clamping assembly on top. The positioning clamping assembly includes a motor fixedly installed inside the worktable, with the motor's output shaft connected to a connecting frame. A placement platform is located on top of the connecting frame, and fixing rods are fixedly connected to both sides of the connecting frame. Each of the two fixing rods has an extension rod extending outwards, and a fixing block is fixedly connected to the side of the extension rod away from the fixing rod. A first rotating shaft is fixedly connected to the inner side of each fixing block. This positioning fixture for aluminum alloy die castings, with its positioning clamping assembly, allows the angle of the clamping frame to be adjusted according to the size and model of the die casting through the connecting rods, a second spring, and a locking rod. Simultaneously, the clamping frame and the die casting maintain a triangular relationship, enhancing the stability of the clamping frame in holding the die casting.

[0004] However, in actual use, due to its own structural limitations, this structure can only be used to position and fix irregular castings by pressing down on both ends. Its fixing force is limited and cannot form a firm and stable clamping force on the side of the irregular casting. The external force of subsequent processing cannot be kept stable. At the same time, it cannot efficiently remove flying waste chips during the processing of irregular castings. It cannot meet the daily use needs. Therefore, it is urgent to design an irregular casting positioning fixture to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for irregularly shaped castings, in order to solve the problem mentioned in the background art that, in actual use, the existing structure is limited by its own structure and can only be used to position and fix irregularly shaped castings by pressing down on both ends. The fixing force is limited and cannot form a firm and stable clamping force on the side of the irregularly shaped casting. The external force for subsequent processing cannot be kept stable, and it is also impossible to efficiently remove flying waste chips during the processing of irregularly shaped castings, thus failing to meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for irregularly shaped castings, including a processing frame, a limiting groove starting from the center of the surface of the processing frame, docking components provided at both ends of the surface of the processing frame, and an adjustment component provided at the bottom end of the processing frame;

[0007] The docking assembly includes a fixed arc frame and a movable arc frame. The fixed arc frame is fixedly connected to one end of the surface of the processing frame, and the movable arc frame is movably connected to the other end of the surface of the processing frame. Both the fixed arc frame and the movable arc frame are fixedly connected to an air control frame at their points of separation.

[0008] The control component includes an adjustable base frame, which is fixedly connected to the center of the bottom of the processing frame, and a drive motor is installed inside one end of the adjustable base frame.

[0009] Preferably, one end of the drive motor is fixedly connected to a reciprocating lead screw, and a lead screw slide is sleeved on the outer surface of the reciprocating lead screw.

[0010] Preferably, an air control pump is provided at one end of the air control frame, and telescopic airbags are evenly arranged inside the air control frame.

[0011] Preferably, a clamp body is movably connected to the inner wall of the fixed arc frame and the movable arc frame, and a chip suction fan is provided at one end of the fixed arc frame and the movable arc frame.

[0012] Preferably, the inner wall of the movable arc frame is provided with chip suction grooves at both the upper and lower ends, and the two ends of the movable arc frame are provided with connecting strips.

[0013] Preferably, a positioning pad is provided at the center of the surface of the processing frame, and the positioning pad is adapted to the bottom of the movable arc frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This irregular casting positioning fixture, through its machining frame, limiting slide groove, fixed arc frame, movable arc frame, air control frame, adjusting base frame, drive motor, reciprocating lead screw, lead screw slide, air control pump, telescopic airbag, and fixture body, enables the equipment to perform positioning and clamping operations more suitably for irregular castings. In actual use, the operator first places the irregular casting in the center of the fixed arc frame, then starts the drive motor at one end of the adjusting base frame to drive the reciprocating lead screw, which then works in conjunction with the outer surface sleeve... The lead screw slide causes the movable arc frame to slide along the limiting groove on the surface of the processing frame, enabling the fixed arc frame and the movable arc frame to adapt and connect. At the same time, the air control pump at one end of the air control frame is started to inflate and expand all the telescopic air bladders inside the air control frame. This allows the clamping body at one end to perform a uniform multi-point adaptation and clamping operation on the side of the irregular casting, improving the fixing force of the irregular casting inside the fixed arc frame and the movable arc frame, ensuring the stability of the irregular casting in subsequent processing, and demonstrating the practicality of the equipment design.

[0016] This irregular casting positioning fixture, through its machining frame, fixed arc frame, movable arc frame, chip suction fan, chip suction mesh groove, and connecting strip, further improves the overall efficiency of the equipment. In daily use, the operator first seals the two ends of the fixed arc frame and the movable arc frame with the connecting strip, then starts the chip suction fan at one end of each arc frame, and then performs a circular suction operation in conjunction with the chip suction mesh grooves on the upper and lower inner walls of the fixed and movable arc frames to remove the waste chips around the irregular casting during machining, ensuring a clean machining environment and demonstrating the comprehensiveness of the equipment design.

A gas control frame 5 is fixedly connected to both the fixed arc frame 3 and the movable arc frame 4 at points away from each other. A fixture body is movably connected to the inner walls of the fixed arc frame 3 and the movable arc frame 4. 12. A chip suction fan 13 is provided at one end of the fixed arc frame 3 and the movable arc frame 4. A chip suction mesh groove 14 is provided at both ends of the inner wall of the movable arc frame 4. A connecting strip 15 is provided at both ends of the movable arc frame 4. A positioning pad 16 is provided at the center of the surface of the processing frame 1. The positioning pad 16 is adapted to the bottom of the movable arc frame 4. The air control pump 10 at one end of the air control frame 5 is started to perform the inflation and expansion operation of all the telescopic airbags 11 inside the air control frame 5, so that the clamp body 12 at one end performs a uniform multi-point matching and clamping operation on the side of the irregular casting.

[0025] The control assembly includes an adjusting base frame 6, which is fixedly connected to the center of the bottom of the processing frame 1. A drive motor 7 is installed inside one end of the adjusting base frame 6, and a reciprocating lead screw 8 is fixedly connected to one end of the drive motor 7. A lead screw slide 9 is sleeved on the outer surface of the reciprocating lead screw 8. An air control pump 10 is installed at one end of the air control frame 5, and telescopic airbags 11 are evenly arranged inside the air control frame 5. When the drive motor 7 at one end of the adjusting base frame 6 is started, it drives the reciprocating lead screw 8, which, in conjunction with the lead screw slide 9 sleeved on the outer surface, drives the movable arc frame 4 to slide along the limiting groove 2 on the surface of the processing frame 1, thereby achieving the matching and connection between the fixed arc frame 3 and the movable arc frame 4.

[0026] Working principle: In use, the operator first places the irregular casting inside the center of the fixed arc frame 3, then starts the drive motor 7 at one end of the adjusting base frame 6 to drive the reciprocating lead screw 8. This, in conjunction with the lead screw slide 9 fitted on the outer surface, drives the movable arc frame 4 to slide along the limiting groove 2 on the surface of the processing frame 1, achieving fitting and connection between the fixed arc frame 3 and the movable arc frame 4. Simultaneously, the air pump 10 at one end of the air control frame 5 is started to inflate and expand all the telescopic airbags 11 inside the air control frame 5, causing the clamp body 12 at one end to perform uniform multi-point positioning on the side of the irregular casting. The mating and clamping operation improves the fixing force of the irregular casting inside the fixed arc frame 3 and the movable arc frame 4, ensuring the stability of the irregular casting in subsequent processing. In daily use, the operator first seals the two ends between the fixed arc frame 3 and the movable arc frame 4 with the mating strip 15, and then starts the chip suction fan 13 at one end of each of the fixed arc frame 3 and the movable arc frame 4. Then, in conjunction with the chip suction mesh grooves 14 on the upper and lower inner walls of the fixed arc frame 3 and the movable arc frame 4, a circular suction operation is performed to remove the waste chips around the processing of the irregular casting. The above is the complete working principle of this utility model.
