Description

Technical Field

[0001] This utility model relates to the field of mold component processing technology, and in particular to a multi-angle fixing fixture for mold component processing. Background Technology

[0002] The machining accuracy and efficiency of mold components directly affect the overall performance and production cycle of the mold. With the increasing complexity and precision of mold structures, higher requirements are placed on the fixtures used in the component machining process. Currently, traditional mold component fixtures have significant limitations in practical applications and are unable to meet the modern demands for high-precision and high-efficiency machining.

[0003] Traditional tooling often uses a single-angle fixing method, fixing parts with rigid structures such as bolts and pressure plates. This method cannot meet the multi-angle processing requirements of complex-shaped mold parts such as polygons and irregular shapes. As a result, when performing processes such as inner wall grinding and curved surface processing, it is necessary to frequently disassemble and re-clamp the parts, which reduces production efficiency. Moreover, after the existing tooling has completed the fixing of the parts, the grinding equipment needs to be started manually, and the fixing force and position cannot be adjusted in real time during the grinding process, making it difficult to dynamically optimize the processing parameters according to the processing progress. Therefore, this utility model proposes a multi-angle fixing tooling for mold part processing. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-angle fixing fixture for processing mold parts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multi-angle fixing fixture for processing mold parts includes a base, a turntable rotatably connected to the upper end of the base, a rotating mechanism for rotating and grinding polygonal parts installed at the lower end of the base, a clamping mechanism for clamping polygonal parts installed at the upper end of the turntable, and a worktable rotatably connected to the inner side of the turntable.

[0007] Preferably, the rotating mechanism includes a fixed frame fixedly connected to the base, a motor is mounted on one side of the fixed frame, a first rotating shaft is fixedly connected to the output shaft of the motor, a first bevel gear is fixedly connected to the outer side of the first rotating shaft, a second bevel gear is meshed with the outer side of the first bevel gear, a sleeve is fixedly connected to the inner side of the second bevel gear, the outer side of the sleeve is fixedly connected to the turntable, and the outer side of the sleeve passes through the fixed frame.

[0008] Preferably, a second rotating shaft is rotatably connected to the inner side of the sleeve, and a third bevel gear is fixedly connected to the lower end of the second rotating shaft. The outer side of the third bevel gear is meshed with the first bevel gear.

[0009] Preferably, the outer side of the second rotating shaft is rotatably connected to the worktable, and a fixing rod is fixedly connected to the upper end of the second rotating shaft. Two sets of symmetrical grinding blocks are fixedly connected to both ends of the fixing rod.

[0010] Preferably, the clamping mechanism includes two sets of mounting blocks fixedly connected to the upper end of the turntable, and an electric telescopic rod is fixedly connected to the side of the two sets of mounting blocks that are close to each other. The output shafts of the two sets of electric telescopic rods are fixedly connected to clamping blocks.

[0011] Preferably, a connecting rod is fixedly connected to the outer side of the output shaft of the electric telescopic rod, a flexible hose is fixedly connected to the inner side of the connecting rod, a storage tank is fixedly connected to one end of the flexible hose, the lower end of the storage tank is fixedly connected to the mounting block, and an electromagnetic spray head is fixedly connected to the other end of the flexible hose.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device utilizes a first bevel gear to simultaneously drive a second and a third bevel gear, causing the turntable to rotate clockwise while the grinding block rotates counterclockwise at high speed. This results in a more uniform cutting force on the inner wall of the polygonal part. An electric telescopic rod drives the clamping block to move towards the part, and the precise extension and retraction of the output shaft achieves adaptive clamping, reducing clamping errors. A connecting rod drives the hose and electromagnetic spray head to move synchronously, ensuring that after grinding, the anti-rust coating can be delivered to the inside of the part through the electromagnetic spray head immediately. Combined with the centrifugal force generated by the rotation of the grinding block, the coating can be evenly applied to the inner wall of the part, improving efficiency compared to manual spraying.

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1 - Figure 4 The multi-angle fixing fixture for processing mold parts shown includes a base 1, a turntable 2 rotatably connected to the upper end of the base 1, a rotating mechanism 3 for rotating and grinding polygonal parts installed at the lower end of the base 1, a clamping mechanism 4 for clamping polygonal parts installed at the upper end of the turntable 2, and a worktable 5 rotatably connected to the inner side of the turntable 2.

[0022] In this embodiment, the rotating mechanism 3 includes a fixed frame 31 fixedly connected to the base 1. A motor 32 is installed on one side of the fixed frame 31. The output shaft of the motor 32 is fixedly connected to a first rotating shaft 33. A first bevel gear 34 is fixedly connected to the outer side of the first rotating shaft 33. A second bevel gear 35 is meshed with the outer side of the first bevel gear 34. A sleeve 36 is fixedly connected to the inner side of the second bevel gear 35. The outer side of the sleeve 36 is fixedly connected to the turntable 2. The outer side of the sleeve 36 passes through the fixed frame 31.

[0023] Specifically, the fixed frame 31 provides stable support for the motor 32 and transmission components, ensuring the rigidity of the power transmission path. The motor 32, as a power source, drives the first rotating shaft 33 to rotate through the output shaft. The first rotating shaft 33 transmits the power of the motor 32 to the first bevel gear 34. The first bevel gear 34 meshes with the second bevel gear 35, changing the power direction from axial to radial. The second bevel gear 35 receives the power from the first bevel gear 34 and drives the sleeve 36 to rotate. The sleeve 36, as a transmission medium, transmits the rotational motion to the turntable 2 and passes through the fixed frame 31 to maintain the degree of rotational freedom.

[0024] In this embodiment, a second rotating shaft 37 is rotatably connected to the inner side of the sleeve 36, and a third bevel gear 38 is fixedly connected to the lower end of the second rotating shaft 37. The outer side of the third bevel gear 38 is meshed with the first bevel gear 34.

[0025] Specifically, the second rotating shaft 37 is nested inside the sleeve 36 and rotates in the opposite direction to the sleeve 36 through an independent bearing. The third bevel gear 38 meshes with the first bevel gear 34 and transmits power in the opposite direction to the second rotating shaft 37, driving the grinding block 310 to rotate counterclockwise in the opposite direction to the sleeve 36.

[0026] In this embodiment, the outer side of the second rotating shaft 37 is rotatably connected to the worktable 5, and a fixing rod 39 is fixedly connected to the upper end of the second rotating shaft 37. Two sets of symmetrical grinding blocks 310 are fixedly connected to both ends of the fixing rod 39.

[0027] Specifically, the worktable 5 is connected to the second rotating shaft 37 via a bearing, allowing the second rotating shaft 37 to rotate independently without interfering with the fixed state of the worktable 5. The fixing rod 39 converts the rotational motion of the second rotating shaft 37 into the radial rotation of the grinding block 310. The grinding block 310 is symmetrically distributed at both ends of the fixing rod 39 and contacts the inner wall of the polygonal accessory through reverse rotation, thereby achieving synchronous grinding.

[0028] In this embodiment, the clamping mechanism 4 includes two sets of mounting blocks 41 fixedly connected to the upper end of the turntable 2. Electric telescopic rods 42 are fixedly connected to the side of the two sets of mounting blocks 41 that are close to each other. Clamping blocks 43 are fixedly connected to the output shafts of the two sets of electric telescopic rods 42.

[0029] Specifically, the mounting block 41 serves as the base of the clamping mechanism 4, is fixed on the turntable 2 and rotates synchronously with it, and the electric telescopic rod 42 controls the displacement of the clamping block 43 through the extension and retraction of the output shaft, so as to clamp or release the polygonal part. The inner surface of the clamping block 43 fits against the outer wall of the polygonal part, providing a uniform clamping force to prevent the workpiece from shifting.

[0030] In this embodiment, a connecting rod 44 is fixedly connected to the outer side of the output shaft of the electric telescopic rod 42, a hose 45 is fixedly connected to the inner side of the connecting rod 44, a storage tank 46 is fixedly connected to one end of the hose 45, the lower end of the storage tank 46 is fixedly connected to the mounting block 41, and an electromagnetic spray head 47 is fixedly connected to the other end of the hose 45.

[0031] Specifically, the linkage 44 links the electric telescopic rod 42 and the hose 45 to ensure that the electromagnetic spray head 47 moves synchronously with the clamping block 43. The hose 45 connects the storage tank 46 and the electromagnetic spray head 47 to deliver the anti-rust coating. The storage tank 46 stores the coating and supplies it to the hose 45 by gravity or pressure. The electromagnetic spray head 47 is opened and closed under control to accurately spray the coating onto the inner wall of the polished parts, and the rotation of the polishing block 310 helps to distribute the coating evenly.

[0032] Working principle: When using this equipment, the polygonal part is placed on the upper end of the worktable 5. The motor 32 on the fixed frame 31 is started. The motor 32 drives the first rotating shaft 33 and the first bevel gear 34 to rotate through the output shaft. The first bevel gear 34 meshes with the second bevel gear 35, driving the sleeve 36 to rotate. The sleeve 36 drives the turntable 2 to rotate, and the turntable 2 drives the clamping mechanism 4 to rotate as a whole through the mounting block 41. The electric telescopic rod 42 is started. The output shaft of the electric telescopic rod 42 pushes the clamping block 43 to move towards the polygonal part until the inner surface of the clamping block 43 is tightly attached to the outer wall of the part, completing the clamping. At the same time, the first bevel gear 34 meshes with the second bevel gear 35 and the third bevel gear 38: the second bevel gear 35 drives the sleeve 36 to rotate clockwise, while the third bevel gear 38 drives the second rotating shaft 37 to rotate counterclockwise, realizing the opposite movement of the turntable 2 and the grinding block 310. The second rotating shaft 37 drives the grinding block 310 to rotate via the fixed rod 39, causing the outer side of the grinding block 310 to contact the inner wall of the polygonal fitting. Internal grinding is completed through bidirectional rotation. The output shaft of the electric telescopic rod 42 pulls the hose 45 via the fixedly connected connecting rod 44, causing the electromagnetic spray head 47 at the end of the hose 45 to move synchronously with the clamping block 43 above the fitting. After grinding, the electromagnetic spray head 47 is activated, and the anti-rust coating in the storage tank 46 is transported to the interior of the fitting through the hose 45 and evenly coated onto the inner wall by the centrifugal force of the rotating grinding block 310.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
