Abstract

The utility model relates to an index head, aiming at solving the problems of high requirement on manufacturing accuracy and high process cost of the existing index heads. The index head is characterized in that the upper circumferential surface of the spindle (9) of the index head is provided with a plurality of Z-shaped grooves (10) which are communicated with each other; the outside of the spindle (9) is a fixed unity of a spindle (8) and an index plate (5); a ball (6) which protrudes from the inside of the spindle (8) is fixed on the spindle (8) and the index plate (5); and the ball (6) and the grooves (10) are matched in clearance. The index head is characterized by easy production, low cost and simple operation.

Description

A kind of dividing head

Technical field:

The utility model belongs to a kind of dividing head, relates in particular to a kind of dividing head of holing on the used gas anchor in oil field.

Background technology:

At present, the problem of calibration is difficult to resolve and determines very much when especially holing to gas anchor on the oil field during boring, generally adopts line boring, but line boring poor accuracy, efficient are low, are not suitable for producing in enormous quantities.Some dividing heads mostly are gear or worm and gear calibration greatly now, and the accuracy of manufacture requires high, and concerning the not high workpiece of some required precisions, processing cost increases.

The utility model content:

Require the deficiency high, that processing cost is high in order to overcome the existing dividing head accuracy of manufacture, the utility model provides a kind of dividing head, and this dividing head has simple, the cost characteristics low, simple to operate made.

The technical solution of the utility model is: a kind of dividing head, comprise main shaft, dividing head spindle, dividing head spindle upper edge periphery has several " it " font grooves that communicates, the entity that the main shaft outside has main shaft and index dial to fix, main shaft and index dial are fixed with the ball that protrudes main shaft inside jointly, and ball and groove are matched in clearance.

The utlity model has following beneficial effect: owing to take such scheme, ball on the main shaft and the groove matched in clearance on the dividing head spindle, cylinder promotes dividing head spindle when left movement, relatively ball moves right along groove, when it moves to the middle part of groove, be subjected to stopping of tip, the place ahead, the trend that moves down along the inclined-plane is arranged, thereby drive the dividing head spindle rotation; In like manner, move right when cylinders retract drives dividing head spindle, relatively ball along groove to left movement, another drives the dividing head spindle rotation, and ball moves one back and forth like this, the angle of circumference in a hole of dividing head spindle rotation, and so forth, can realize the calibration of lathe.The key component of this device processing has only dividing head spindle, and whole manufacturing is simple, cost is low, and simple to operate, only needs control cylinder to get final product.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the cutaway views along A-A in the accompanying drawing 1;

Accompanying drawing 3 is expanded views of dividing head spindle in the utility model.

1-cylinder among the figure, 2-cylinder terminal pad, 3-guide pillar, 4-sliding plate, 5-index dial, 6-steel ball, 7-bearing, 8-main shaft, 9-dividing head spindle, 10-ball.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, a kind of dividing head, comprise main shaft 8, place the dividing head spindle 9 of main shaft 8 inside, there is bearing 7 main shaft 8 outsides, and main shaft 8 right-hand members and index dial 5 are fixed together, and index dial 5 and sliding plate 4 are fixed by pin, guide pillar 3 one ends are fixed on the sliding plate 4, the other end passes cylinder terminal pad 2, and when cylinder 1 stretched, guide pillar 3 can pass in and out in cylinder terminal pad 2.Dividing head spindle 9 upper edge peripheries have several " it " font grooves 10 that communicates, several trough 10 is uniformly distributed along the circumference, its quantity is 2 times of quantity of the required boring of circumference, the shape of groove 10 as shown in Figure 3, be similar to corrugated, the semicircle of two ends for alternately staggering, the semicircle of both sides is relative with an inclined-plane respectively.Main shaft 8 and index dial 5 common fixedly balls 6, the inside that ball 6 protrudes main shaft 8, and ball 6 is a matched in clearance with groove 10.

Boring 6 holes with a circumference below is that example illustrates:

As from the foregoing, the quantity of groove 10 is 2 times of quantity of circumference boring, and therefore, groove 10 is 12, both every 30 ° be a groove 10, about alternately arrange and communicate.When needs are holed, control cylinder 1, when cylinder 1 stretches out left, promote dividing head spindle 9 to left movement, 6 on ball in the groove 10 moves right relatively along groove 10, and when moving to the middle part of groove 10, the place ahead is stopped and moves downward (as Fig. 3) along the inclined-plane, and dividing head spindle 9 continuation this moment left, makes ball 2 roll into the groove 10 on right side; When cylinder 1 is withdrawn to the right, drive dividing head spindle 9 and move right, 6 on the ball in the groove 10 along groove 10 relatively to left movement, when moving to the middle part of groove 10, the place ahead is stopped and is moved downward along the inclined-plane, makes ball 2 roll into the groove 10 in left side, so far finishes the motion in a boring cycle.

This dividing head is simple in structure, and the key component of processing has only dividing head spindle, and is easy to process, cost is low, and simple to operate, is particluarly suitable for holing on the not high pipe of required precision, making that boring has improved efficient on the used gas anchor in oil field.

Claims

1, a kind of dividing head, comprise main shaft (8), dividing head spindle (9), it is characterized in that: " it " font groove (10) that dividing head spindle (9) upper edge periphery has several to communicate, the entity that main shaft (9) outside has main shaft (8) and index dial (5) to fix, main shaft (8) is fixed with jointly with index dial (5) and protrudes the inner ball (6) of main shaft (8), and ball (6) is a matched in clearance with groove (10).

2, dividing head according to claim 1 is characterized in that: the quantity of groove (10) is 2 times of quantity of the required boring of circumference.
