Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, specifically relating to a positioning tooling for forging processing. Background Technology

[0002] Forgings refer to metal workpieces or blanks obtained through forging. Before further processing, forgings need to be positioned and clamped using positioning fixtures to ensure their stability during processing. Circular forgings are a very common type of forging. When clamping and fixing circular forgings, two arc-shaped clamping plates are often used. By fitting the arc-shaped clamping plates against the outer surface of the circular forging and applying clamping force, the circular forging can be positioned and fixed.

[0003] However, the surface curvature of circular forgings of different diameters varies, and a clamping plate with one curvature can only be used for circular forgings of one diameter. This has certain limitations. When it is necessary to position circular forgings of different diameters, the clamping plate needs to be changed repeatedly, and the changing operation is complicated and troublesome. It often requires the use of external auxiliary tools. Therefore, it is necessary to design a new forging positioning fixture to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a forging processing positioning fixture to solve the problems mentioned in the background art, which are that the clamping plate on the positioning fixture can only clamp and limit circular forgings of one diameter, and that the disassembly and replacement of the clamping plate is too troublesome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forging machining positioning fixture, comprising...

[0006] Workbench and placement platform fixed to the surface of the workbench;

[0007] The clamping plate kit includes clamping plates symmetrically distributed on both sides of the placement platform. The clamping plates are arranged sequentially from the inside to the outside, and the outer surface of the inner clamping plate is adapted to the inner surface of the outer clamping plate.

[0008] Hydraulic rods symmetrically connected to the surface of the outermost clamping plate;

[0009] Symmetrical grooves are formed on the surface of the worktable;

[0010] The plug-in assembly includes a plug-in rod fixed to the bottom of the clamp, a plug-in seat slidably installed inside the slide groove, and a plug-in slot formed on the surface of the plug-in seat and inserted into the plug-in rod.

[0011] Preferably, the clamping plate kit further includes a rubber pad disposed on the outer surface of the clamping plate.

[0012] Preferably, the clamping plate kit further includes a baffle plate fixed to the top of the clamping plate and extending to the top of an inner clamping plate.

[0013] Preferably, except for the outermost clamping plate, each clamping plate has two symmetrically fixed plug rods at its bottom, and the outer surface of the plug rods is in contact with the inner surface of the plug groove.

[0014] Preferably, the two sides of the connector are in contact with the inner walls of the two sides of the slide groove, and the top of the connector extends out of the slide groove.

[0015] Preferably, the plug-in assembly further includes a roller, which is disposed at the bottom of the plug-in base and rolls in contact with the slide groove.

[0016] Preferably, the plug-in assembly further includes a connecting plate, which is fixedly connected between the plug-in seats on both sides, and a connecting groove is provided through the sliding groove for the connecting plate to pass through.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By designing a clamping plate kit consisting of multiple clamping plates, when it is necessary to clamp and position circular forgings of different diameters, the clamping plates on the clamping plate kit can be used to clamp and fix the circular forgings.

[0028] The worktable 100 and the placement table 200 fixed on the surface of the worktable 100 can place the round forging to be processed on the placement table 200.

[0029] The clamping plate kit 300 includes clamping plates 301 symmetrically distributed on both sides of the placement table 200. The clamping plates 301 are arranged sequentially from the inside to the outside. The outer surface of the inner clamping plate 301 is adapted to the inner surface of the outer clamping plate 301. The curvature of the inner and outer clamping plates 301 is different. The curvature of multiple clamping plates 301 is adapted to the curvature of several common round forgings.

[0030] Hydraulic rods 400 are symmetrically connected to the surface of the outermost clamping plate 301. The clamping plate 301 is pushed by the hydraulic rods 400 to apply compressive force.

[0031] The slide grooves 500 are symmetrically opened on the surface of the workbench 100, and the clamping plate 301 slides along the direction of the slide grooves 500;

[0032] The plug-in assembly 600 includes a plug-in rod 601 fixed to the bottom of the clamping plate 301, a plug-in seat 602 slidably installed inside the slide groove 500, and a plug-in groove 603 formed on the surface of the plug-in seat 602 and inserted into the plug-in rod 601. The plug-in rod 601 can be inserted into the plug-in groove 603 to complete the installation of the clamping plate 301. When the hydraulic rod 400 pushes the clamping plate 301 to move, the plug-in seat 602 can slide inside the slide groove 500. If it is necessary to disassemble the clamping plate 301, simply pull the clamping plate 301 upwards and pull the plug-in rod 601 out from the inside of the plug-in groove 603.

[0033] In this embodiment, preferably, the clamping plate kit 300 further includes a rubber pad 302, which is disposed on the outer surface of the clamping plate 301 and plays a buffering and protective role between the clamping plates 301.

[0034] In this embodiment, preferably, the clamping plate kit 300 further includes a baffle 303, which is fixed to the top of the clamping plate 301 and extends to the top of the inner clamping plate 301. When multiple clamping plates 301 are close together, the baffle 303 can limit the clamping plates 301 and prevent them from moving upward. When disassembling the clamping plate 301, the clamping plate 301 can be moved first to remove it from the bottom of the baffle 303, and then pulled upward to complete the disassembly.

[0035] In this embodiment, preferably, except for the outermost clamping plate 301, each clamping plate 301 has two symmetrically fixed plug rods 601 at its bottom. The outer surface of the plug rod 601 is pressed against the inner surface of the plug groove 603 to improve the plugging stability between the plug rod 601 and the plug groove 603.

[0036] In this embodiment, preferably, the two sides of the plug-in seat 602 are in contact with the inner walls of the two sides of the slide groove 500, and the top of the plug-in seat 602 extends out of the slide groove 500. The protruding part is slightly small, so that it is easy for personnel to move the plug-in seat 602, thereby facilitating the personnel to put the clamp 301 into place.

[0037] In this embodiment, preferably, the plug-in assembly 600 further includes a roller 604, which is disposed at the bottom of the plug-in base 602 and rolls in contact with the slide groove 500 to improve the smoothness of the plug-in base 602 during movement.

[0038] In this embodiment, preferably, the plug-in assembly 600 further includes a connecting plate 605, which is fixedly connected between the plug-in seats 602 on both sides. A connecting groove 700 is provided through the sliding grooves 500 for the connecting plate 605 to pass through, thereby fixing the plug-in seats 602 on both sides together, improving the stability of the plug-in seats 602 and making them less likely to fall off.
