Abstract

The utility model relates to a multi-connected turning tool, which comprises a first knife handle (1), a first gasket (2), a second knife handle (3), a second gasket (4), a top thread (5), a second knife blade (6) and a first knife blade (7). The first knife handle is composed of a knife rod and a connecting rod that are connected in a T shape; the first knife blade is mounted at the front end of the symmetrical central line of the knife rod; the second knife handle is mounted on the connecting rod by the first gasket; the distance between the symmetrical central line of the second knife handle and the symmetrical central line of the knife rod is H, and the H is equal to the center distance of double channels of a turntable bearing and is determined by length of the connecting rod and thickness of the first gasket; the second knife handle is fixed to the connecting rod of the first knife handle by the second gasket and the top thread when the H is satisfied; the second knife blade is also mounted at the front end of the symmetrical central line of the second knife handle; and the mounted first knife blade is parallel to the mounted second knife blade. The processing demand of the double channels of the turntable bearing can be realized and the processing accuracy and the working efficiency can be improved.

Description

A kind of turning cutting tool that joins more

Technical field

The utility model belongs to the bearing processing apparatus technical field, refers more particularly to a kind of turning cutting tools that join that are used to process the turntable bearing double channel more.

Background technology

The double channel turning processing of turntable bearing is the technological difficulties that need to be resolved hurrily in the present bearing industry.

General way is that two parallel channel of turntable bearing are processed respectively in the industry now; This processing method causes ditch heart distance, parallel error, diameter phase mutual deviation of two raceway grooves etc. not guarantee fully; And be difficult for finishing; Directly have influence on the main performance index of finished product bearing, processing has a big risk, efficient is low.

Summary of the invention

For addressing the above problem; The utility model has designed a kind of turning cutting tools that join that are used to process the turntable bearing double channel more; Should join the double channel that turning cutting tool can be processed turntable bearing simultaneously more; Precision machining, the ditch heart that can effectively guarantee the turntable bearing double channel has improved working (machining) efficiency apart from, parallel error and diameter difference.

In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:

The centre-to-centre spacing of setting the turntable bearing double channel is H.

A kind of turning cutting tool that joins comprises first handle of a knife, first pad, second handle of a knife, second pad, jackscrew, first blade and second blade more.

Said first handle of a knife is made up of knife bar and connecting rod; Said knife bar and said connecting rod are the T type and connect; Symmetrical center line front end at said knife bar is equipped with first blade; Be fitted with second handle of a knife through first pad on the said connecting rod, apart from being H, said H equals the centre-to-centre spacing of turntable bearing double channel between the symmetrical center line of the said knife bar of symmetrical center line distance of second handle of a knife; Said H confirms by the thickness size of its first pad when guaranteeing that said connecting rod is definite value, second handle of a knife is fixed on the said connecting rod of first handle of a knife through second pad and jackscrew again satisfying under the said H; Symmetrical center line front end at second handle of a knife also is equipped with second blade, and first blade is identical with the physical dimension of second blade, and second blade after first blade after the installation and the installation is parallel to each other.

Owing to adopted technical scheme as stated, the utlity model has following superiority:

1, the utility model is simple for structure, and operating personnel can be installed easily and efficiently;

2, the utility model can be realized the process requirements of turntable bearing double channel, improves turntable bearing double channel machining accuracy, increases work efficiency, and guarantees the high reliability of finished product turntable bearing;

3, utilize the utility model can process the identical single raceway groove bearing of two nested structures simultaneously;

If 4 increase the 3rd handle of a knife or n handle of a knife on the utility model basis, then can process three cover or the identical single raceway groove bearings of n nested structure simultaneously.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among Fig. 1: 1-first handle of a knife; 2-first pad; 3-second handle of a knife; 4-second pad; The 5-jackscrew; 6-second blade; 7-first blade.

The specific embodiment

The centre-to-centre spacing of at first setting the turntable bearing double channel is Hmm.

In conjunction with Fig. 1, many couplet turning cutting tool that the utility model a kind of is used to process the turntable bearing double channel comprises first handle of a knife 1, first pad 2, second handle of a knife 3, second pad 4, jackscrew 5, second blade 6 and first blade 7.

Said first handle of a knife 1 of the utility model is made up of knife bar and connecting rod; Said knife bar and said connecting rod are the T type and connect; Symmetrical center line front end at said knife bar is equipped with first blade 7; Be fitted with between the symmetrical center line of the said knife bar of symmetrical center line distance of second handle of a knife, 3, the second handle of a knifes 3 apart from being Hmm through first pad 2 on the said connecting rod, said Hmm equals the centre-to-centre spacing of turntable bearing double channel; Said Hmm confirms by the thickness size of its first pad 2 when guaranteeing that said connecting rod is definite value, second handle of a knife 3 is fixed on the said connecting rod of first handle of a knife 1 through second pad 4 and jackscrew 5 again satisfying under the said Hmm; It is identical with the physical dimension of second blade 6 at the symmetrical center line front end of second handle of a knife 3 second blade, 6, the first blades 7 to be installed also, first blade 7 after the installation with install after second blade 6 be parallel to each other.

During use; The connecting rod that elder generation adjusts first handle of a knife 1 through first pad 2 makes it to equate with the centre-to-centre spacing of turntable bearing double channel with the centre-to-centre spacing Hmm of second handle of a knife 3; And first blade 7 is identical with the structure of second blade 6 with second blade, 6, the first blades 7 on the symmetrical center line front end of the symmetrical center line front end of first handle of a knife, 1 connecting rod and second handle of a knife 3 is equipped respectively.Utilizing hexagon-headed bolt that the utility model is fixed on the lathe cutter saddle again gets final product.

Add man-hour, cut when starting lathe and can realize the two raceway of turntable bearing.

Be provided with from the structure of the utility model, the utility model can also be processed the identical single raceway groove bearing of two nested structures simultaneously.

If prolong the connecting rod length of first handle of a knife 1 the 3rd handle of a knife or n handle of a knife can also be set, then can process three cover or the identical single raceway groove bearings of n nested structure simultaneously.So the utility model joins " join " in the turning cutting tool more more and means >=2, or refer to two with plural parallelly connected turning cutting tool.
