Description

Technical Field

[0001] This utility model relates to the field of forging processing technology, specifically a forging milling fixture with positioning function. Background Technology

[0002] Milling is an important auxiliary process in metal forging, mainly used for finishing and complex-shaped parts to improve accuracy and surface quality. When roughing ferrous metal forging blanks, conventional milling is more suitable because it can effectively alleviate the impact between the tool and the surface hard skin or uneven allowance, reduce vibration and tool wear. During the milling process, it is necessary to strictly control the milling force, milling heat and coolant usage to avoid damage to the workpiece and tool. Milling methods include the use of horizontal or vertical milling machines, which are suitable for mass production to improve efficiency.

[0003] When milling forgings, they need to be positioned and fixed. However, the existing positioning structure is relatively complex and cumbersome, which reduces the efficiency of milling forgings. Therefore, we designed a forging milling fixture with positioning function to increase the efficiency of forging milling. Utility Model Content

[0004] The purpose of this utility model is to provide a forging milling fixture with positioning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forging milling fixture with positioning function, comprising a working platform for milling forgings, five horizontally equidistant grooves are provided on the working platform, and a slider is slidably connected in the grooves. An elastic ball is provided at the bottom of the slider, a fixing block is fixedly connected to the slider, and an annular groove is provided around the fixing block on the slider, with an air bladder provided in the annular groove. A cylinder is fixedly connected to the fixing block, and a fixed bearing is provided at the telescopic end of the cylinder. A pressure plate is provided on the fixed bearing, and a limit groove is provided under the pressure plate. A positioning plate is slidably connected in the limit groove, and a locking bolt is provided on the positioning plate.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Preferably, the bottom of the slider is provided with four elastic balls, and a strong spring is sleeved on the elastic balls. The bottom of the slider is provided with a groove that matches the elastic balls and the strong spring. Only one-third of the ball is exposed under the slider. By providing elastic balls, the resistance of the slider movement can be reduced, and at the same time, the elastic balls can be prevented from separating from the slider.

[0008] Preferably, the air inlet of the airbag is connected to a right-angle tube, and the end of the right-angle tube away from the airbag is connected to a flexible tube. The right-angle tube is connected to the fixing block by a buckle. By setting the airbag, it is easy to reduce the gap between the slider and the groove, and squeeze the elastic ball to retract it into the slider, thereby positioning and fixing the moving slider.

[0009] Preferably, the telescopic end of the cylinder is provided with a convex block, and the convex block is engaged with the inner ring of the fixed bearing and fixedly connected to the inner ring. The outer ring of the fixed bearing is fixedly connected to the pressure plate. By providing a convex block and a fixed bearing at the top of the cylinder, the pressure plate can be rotated, and the pressure plate can be adjusted according to actual use needs.

[0010] Preferably, the pressure plate has a groove adapted to the fixed bearing, and the pressure plate has a number of screw holes adapted to the locking bolts at equal intervals in the transverse direction. By setting the locking bolts on the pressure plate, it is convenient to fix the positioning plate that moves at the bottom of the pressure plate.

[0011] Preferably, the positioning plate is T-shaped, and length and height scales are respectively provided on the positioning plate and the pressure plate. By setting the positioning plate, it is convenient for multiple positioning plates on the worktable to position the forging.

[0012] Beneficial effects

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] This invention features a slider and a cylinder on the working platform, which facilitates the movement of the slider, cylinder, and pressure plate on the platform. Elastic balls and air bladders on the slider facilitate its movement and locking. Fixed bearings and positioning plates on the pressure plate allow for the positioning and clamping of forgings on the working platform using multiple positioning and pressure plates. This results in a fixture that effectively positions forgings, increasing the efficiency of forging milling. Attached Figure Description
