Description

Special tooling for machining valve stuffing box

The technical field is as follows: the utility model relates to a dedicated tool equipment of valve stuffing box processing.

Background art: the stuffing box is a commonly used valve component, typically machined using a lathe. The frock clamp in the course of working all utilizes a bent plate at present, and the work piece of treating the processing is connected to the bent plate, and the bent plate is cliied to the chuck of lathe, and according to work piece specification and dimension requirement, not hard up the clamping jaw of chuck again, adjustment bent plate to suitable position, and the positioning accuracy of adjustment is poor, and operating efficiency is not high, and the processingquality of work piece is difficult to guarantee, and current valve stuffing box processing frock design is not ideal enough.

The invention content is as follows: the utility model provides a not enough to prior art, the utility model provides a rational in infrastructure, the accurate special frock of valve stuffing box processing of adjustment.

The utility model comprises a right-angle bent plate, a workpiece to be processed is connected on the horizontal part of the bent plate, a reference disc can be connected on the main shaft of a processing lathe in a center-coincident manner, the front side of the reference disc is provided with two vertical T-shaped chutes, a vertical positioning straight key is arranged in the middle, two T-shaped nuts are respectively connected on the side wall of the vertical part of the bent plate through locking bolts, the T-shaped nuts are arranged in the T-shaped chutes for matching, and the side wall of the vertical part of the bent plate is also provided with a key groove for matching with the positioning straight key; the horizontal part of the bent plate is provided with a large through hole, the positioning tray is connected in the large through hole, and a workpiece to be processed is connected on the positioning tray.

The utility model discloses a rational in infrastructure, through T type spout and location straight key isotructure on the benchmark disc, the bent plate can adjust the processing position rapidly together with the work piece of treating processing, and the adjustment location is accurate, and the clamping is convenient, and the quality of processing is good, and machining efficiency promotes greatly.

The invention is further described with reference to the following figures and examples.

Description of the drawings: fig. 1 is a schematic diagram of the main structure of the embodiment.

Fig. 2 is a right side view of fig. 1.

Fig. 3 is a schematic sectional view taken along line a-a of fig. 1.

The specific implementation mode is as follows: as shown in fig. 1 to 3, the bending plate 2 is a right-angle bending plate, and the reference disc 1 can be connected to the main shaft of the processing lathe with a center overlapped, that is, the rotation center line of the main shaft and the rotation center line of the reference disc 1 are overlapped. The front of benchmark disc 1 is equipped with two vertical T type spouts 3, and vertical location straight key 4 has been arranged to the centre, and two T type nuts 5 are connected at the vertical portion lateral wall of bent plate 2 through locking bolt 6 separately, and T type nut 5 arranges T type spout 3 in and cooperates, and the vertical portion lateral wall of bent plate 2 still is equipped with keyway 7 and location straight key 4 cooperation. The horizontal part of the bent plate 2 is provided with a large through hole 8, the positioning tray 9 is connected in the large through hole 8, a workpiece 13 to be processed is connected on the positioning tray 9, and a pressing strip 14 is pressed on the top of the workpiece 13 to ensure that the connection is firmer.

When clamping and adjusting are carried out, the T-shaped nut 5 is matched with the T-shaped sliding groove 3, the key groove 7 is matched with the positioning straight key 4, the bent plate 2 and the workpiece 13 can vertically displace on the surface of the reference disc 1, and the locking bolt 6 can be screwed to fix the bent plate and the workpiece after the bent plate and the workpiece are in place. Two bending plate supporting seats 10 positioned below the bending plate 2 can be further connected to the reference disc 1, so that the bending plate 2 and the workpiece 13 are supported more stably.

The upper part of the positioning tray 9 in the embodiment is of a stepped tower structure, so that more workpieces 13 with different caliber sizes can be matched. The front surface of the reference disc 1 is provided with the graduated scale 11 in the vertical direction, so that the operation can be more convenient and accurate during position adjustment. The reference disc 1 is also provided with a counterweight connecting hole 12, so that a counterweight block can be conveniently added when needed.
