Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology for shaft parts, specifically a milling tooling for shaft parts. Background Technology

[0002] Milling is a common process in the machining of shaft parts. Due to the slender structure of shaft parts, stable positioning and reliable clamping are required during milling to ensure machining accuracy and safety.

[0003] In existing technologies, milling fixtures for shaft parts mostly rely on manually tightening bolts to achieve clamping when limiting the shaft parts. This operation is cumbersome and the clamping force is uneven, which can easily lead to workpiece deformation or positioning misalignment. When machining the shape of shaft parts in different circumferential positions, the workpiece needs to be disassembled and repositioned multiple times, which not only increases auxiliary time but also introduces errors due to repeated positioning, affecting machining accuracy. When machining shaft parts with large axial dimensions, there is a lack of auxiliary installation and support components during machining, which makes it inconvenient for operators to clamp the parts and also affects the machining accuracy of the parts. Utility Model Content

[0005] To achieve the above objectives, this utility model discloses a milling fixture for shaft parts. The technical solution includes a base plate, a center seat, and a sliding base. The center seat is installed at one end of the base plate, and the sliding base is installed at the other end of the base plate through an adjusting block. The center seat and the sliding base cooperate to clamp and limit the workpiece.

[0006] The base plate is also provided with a sliding base plate, which is located between the center seat and the sliding base. A clamping block is slidably connected to the sliding base plate. Under the drive of the first hydraulic cylinder, the two sets of clamping blocks clamp and limit the workpiece. The axial positioning of both ends of the workpiece is achieved by the cooperation of the fixed center and the sliding center. With the clamping block on the sliding base plate, the positioning accuracy of the workpiece during the processing is guaranteed, and the processing waste caused by the unstable fixing is reduced.

[0007] The center seat is also provided with an angle adjustment component that drives the workpiece to rotate, thereby adjusting the facing surfaces of the workpiece and the milling cutter.

[0008] As a preferred technical solution of this utility model, a fixed center is connected to the center seat by a center sleeve, and the fixed center corresponds to the position of the sliding base.

[0009] As a preferred technical solution of this utility model, the angle adjustment component includes a positioning sleeve and a drive wheel. The positioning sleeve is rotatably connected to the center sleeve through a bearing, and the positioning sleeve is also provided with a waist-shaped hole that matches the size of the workpiece end face. The center seat is provided with a bidirectional motor, and the drive wheel is provided on the output end of the bidirectional motor. The drive wheel and the positioning sleeve are driven by a transmission belt.

[0010] As a preferred embodiment of this utility model, a support block is connected to the sliding base plate by a spring, and an arc-shaped groove is provided on the opposing surface of the support block and the workpiece for supporting the installation of the workpiece.

[0011] As a preferred technical solution of this utility model, a sliding center is slidably connected to the sliding base through a center bushing. The sliding center is driven by a second hydraulic cylinder. The hydraulic drive method of driving the clamping block with a first hydraulic cylinder and driving the sliding center with a second hydraulic cylinder realizes the automation of the clamping process, reduces the intensity of manual operation, and at the same time, the hydraulic driving force is stable and controllable, avoiding the problem of uneven force during manual clamping.

[0012] As a preferred technical solution of this utility model, the telescopic end of the second hydraulic cylinder is connected to the sliding tip through a drive block. The opposing ends of the drive block and the sliding tip are T-shaped, and the sliding tip is provided with a T-shaped through groove that matches the size of the drive block.

[0013] As a preferred embodiment of this utility model, the bottom of the sliding base plate is connected to the base plate via the first hydraulic cylinder, and a pressing block is slidably connected to the top of the sliding base plate. The telescopic end of the first hydraulic cylinder is connected to the pressing block via a connecting block.

[0014] As a preferred technical solution of this utility model, the clamping blocks are provided in two sets and symmetrically arranged on the sliding base plate. Under the drive of the first hydraulic cylinder, the two sets of clamping blocks clamp and limit the workpiece.

[0015] As a preferred technical solution of this utility model, the two sets of clamping blocks are T-shaped blocks, and the top of the sliding base plate is provided with a T-shaped sliding groove that matches the size of the clamping block. Furthermore, replaceable pads are provided on the facing surfaces of the two sets of clamping blocks. By installing replaceable pads on the clamping blocks, the clamping requirements of workpieces with different diameters and materials can be adapted, thereby increasing the adaptability of the tooling.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this utility model achieves axial positioning of both ends of the workpiece by cooperating with the fixed center and the sliding center, and with the clamping block on the sliding base plate, it ensures the positioning accuracy of the workpiece during the processing and reduces the processing waste caused by unreliable fixing.

[0017] The hydraulic drive method, which uses a first hydraulic cylinder to drive the clamping block and a second hydraulic cylinder to drive the sliding center, automates the clamping process, reduces the intensity of manual operation, and ensures that the hydraulic driving force is stable and controllable, thus avoiding the problem of uneven force during manual clamping.

[0018] The angle adjustment component can drive the workpiece to rotate circumferentially, and the shape processing of different circumferential positions can be completed without disassembling the workpiece. This reduces auxiliary processing time, improves production efficiency, and avoids errors caused by repeated positioning.

[0019] The position of the sliding base can be adjusted by adjusting the blocks to adapt to the processing requirements of workpieces of different lengths;

[0020] By installing replaceable pads on the clamping blocks, the clamping requirements of workpieces of different diameters and materials can be adapted, increasing the adaptability of the tooling.
