Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, specifically to a tooling fixture for positioning and machining the thread of a corner plug body. Background Technology
[0002] Angle plugs are control valves for the air communication and disconnection between railway locomotives, between locomotives and rolling stock, and between rolling stock. Their handles can be lifted and rotated 90° to open and close the air passage.
[0003] When machining the threads of a conventional angle plug, a three-jaw chuck is usually used for clamping and fixing. However, due to the characteristics of the angle plug's own structure, the three-jaw chuck needs to be repeatedly adjusted and used. The stability and convenience of its clamping structure are relatively limited, which is not conducive to the stable machining of the angle plug.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a tooling fixture for positioning the thread of the angle plug body. Utility Model Content
[0005] The purpose of this utility model is to provide a tooling fixture for positioning the thread of a corner plug body, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for positioning and machining the thread of a folding plug body, comprising a fixed plate and side plates. The front side of the fixed plate is symmetrically connected with side plates, and a side limiting bolt is horizontally inserted through the middle of the side plate. A top plate is horizontally installed at the top of the side plate away from the fixed plate, and an upper limiting bolt is vertically inserted through the middle of the top plate. Meanwhile, a bottom plate is horizontally installed at the lower end between the left and right side plates. A limiting block is horizontally provided at the top of the bottom plate away from the fixed plate, and a lower limiting bolt is provided at the bottom of the limiting block. Calibration bolts are horizontally provided on the left and right sides of the limiting block. A leveling bolt is symmetrically inserted vertically through the middle section of the bottom plate.
[0007] Furthermore, the side plate is welded to the fixed plate, and the side limiting bolt is threaded to the side plate.
[0008] Furthermore, one end of the side plate is symmetrically installed on the bottom left and right ends of the top plate using hexagon socket head cap screws, and the bottom plate is fixedly installed on the lower middle end of the two sets of side plates using hexagon socket head cap screws.
[0009] Furthermore, the upper limit bolt is threadedly connected to the top plate, and the top of the upper limit bolt is provided with a square structure close to the hexagonal nut structure side plate.
[0010] Furthermore, the calibration bolt adopts an internal hexagonal bolt structure, and the horizontal thread of the calibration bolt passes through the end of the side plate near the limiting block.
[0011] Furthermore, the lower limit bolt has a vertical thread that penetrates the middle of one end of the side plate near the limit block, and the lower limit bolt is configured with an internal hexagon bolt structure.
[0012] Furthermore, a rectangular notch is provided at one end of the base plate near the fixed plate, and a leveling bolt is threadedly connected to the end of the base plate near the rectangular notch.
[0013] Furthermore, the limiting block is movably disposed between the side plate, the top plate, and the bottom plate, and one end of the side limiting bolt has an internal hexagonal bolt and a hexagonal nut structure.
[0014] This utility model provides a tooling fixture for positioning and machining the thread of a corner plug body, which has the following advantages:
[0015] 1. This utility model, by installing side limiting bolts on the horizontal threads in the middle of the left and right side plates, can limit and clamp the angle plug body on both horizontal left and right sides by horizontal rotation adjustment. By installing upper limiting bolts on the vertical threads in the middle of the top plate, axial rotation in the vertical direction can provide top-down clamping limit for the angle plug body. The limiting block can provide bottom-up clamping limit for the angle plug body by vertical axial rotation of the lower limiting bolt, thereby ensuring the clamping stability of the angle plug body and ensuring the accuracy of processing. In addition, the limiting block can be finely adjusted left and right in the horizontal direction by horizontal axial rotation adjustment of the calibration bolt, thereby providing fine adjustment of the processing axis of the angle plug body and ensuring processing accuracy.
[0016] 2. This utility model features a rectangular opening at one end of the base plate near the fixed plate, which facilitates clamping and limiting of the angle plug body while providing structural clearance, thus ensuring the stability of the angle plug body during clamping and placement. Additionally, two sets of leveling bolts are vertically threaded on one side of the base plate near the rectangular opening. By vertically tightening the leveling bolts, the end of the angle plug body away from the limiting block can be pushed upwards from bottom to top. This, combined with the adjustment of the upper limit bolts, allows for horizontal adjustment of the entire angle plug body, ensuring its levelness within the fixture and guaranteeing machining accuracy. Furthermore, the side plates, top plate, and base plate are interconnected and fixed using internal hex bolts, providing sufficient structural stability while allowing for disassembly for easy maintenance and cleaning of the entire fixture.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] like Figures 1 to 3 As shown, a tooling fixture for positioning and machining the thread of a corner plug includes a fixed plate 1 and side plates 2. Side plates 2 are symmetrically connected to the front of the fixed plate 1, and a side limiting bolt 3 horizontally penetrates the middle of the side plate 2. A top plate 4 is horizontally mounted on the top of the side plate 2 away from the fixed plate 1, and an upper limiting bolt 5 vertically penetrates the middle of the top plate 4. A bottom plate 6 is horizontally mounted on the lower end between the left and right side plates 2. A limiting block 7 is horizontally provided on the top of the bottom plate 6 away from the fixed plate 1, and a lower limiting bolt 8 is provided at the bottom of the limiting block 7. Calibration bolts 9 are horizontally provided on both sides of the limiting block 7. Leveling bolts 10 are symmetrically and vertically penetrated in the middle section of the bottom plate 6. The side plates 2 and... The fixed plates 1 are welded together, and the side limiting bolts 3 are threaded together with the side plates 2. The top of one end of the side plates 2 is symmetrically installed on the bottom left and right ends of the top plate 4 by internal hex bolts. The bottom plate 6 is fixedly installed on the lower middle end of the two sets of side plates 2 by internal hex bolts. The side limiting bolts 3 are installed in the middle of the left and right side plates 2 by horizontal thread and can be adjusted by horizontal rotation. The upper limiting bolts 5 are installed in the middle of the top plate 4 by vertical thread and can be axially rotated in the vertical direction. The limiting block 7 can be axially rotated by the lower limiting bolt 8. In addition, the limiting block 7 can be clamped and limited in four directions by horizontal axial rotation adjustment of the calibration bolt 9.
[0023] like Figures 1 to 3As shown, the upper limit bolt 5 is threadedly connected to the top plate 4, and the top of the upper limit bolt 5 has a square structure and a hexagonal nut structure near the side plate 2. The calibration bolt 9 is an internal hexagonal bolt, and the horizontal thread of the calibration bolt 9 passes through the end of the side plate 2 near the limit block 7. The lower limit bolt 8 is vertically threaded through the middle of the end of the side plate 2 near the limit block 7, and the lower limit bolt 8 is an internal hexagonal bolt. The bottom plate 6 has a rectangular notch at the end near the fixed plate 1, and the leveling bolt 10 is threadedly connected to the bottom plate 6 near the rectangular notch. At one end, the limiting block 7 is movably disposed between the side plate 2, the top plate 4, and the bottom plate 6. One end of the side limiting bolt 3 has an internal hexagonal bolt and hexagonal nut structure. By opening a rectangular opening structure at the end of the bottom plate 6 near the fixed plate 1, it can facilitate the clamping and limiting of the angle plug body while providing structural clearance. By vertically turning the leveling bolt 10, the end of the angle plug body away from the limiting block 7 can be pushed from bottom to top. In conjunction with the adjustment of the upper limit bolt 5, it can be used to adjust the entire angle plug body in the horizontal direction.
[0024] In summary, as Figures 1 to 3 As shown, the tooling fixture for positioning the threaded corner plug body is used by first connecting and fixing the entire fixture to the lathe using the fixing plate 1 and bolts. Then, the corner plug body to be processed is placed horizontally in the middle of the fixture. Then, according to the surface structure of the corner plug body, the side limit bolts 3 in the middle section of the side plate 2 are tightened, and the upper limit bolts 5 in the middle of the top plate 4 are tightened. Next, the lower limit bolts 8 and the calibration bolts 9 on the bottom and left and right sides of the limit block 7 are tightened respectively. In this way, the corner plug body is clamped and limited from four directions: up, down, left, and right. Afterwards, the leveling bolts 10 at one end of the base plate 6 can be tightened to ensure the horizontal consistency of the front and rear ends of the corner plug body. At the same time, by using the limit block 7 in conjunction with the lower limit bolts 8 and the calibration bolts 9, the machining axis of the corner plug body can be finely adjusted to ensure the accuracy of subsequent processing.
