Abstract

The utility model discloses a tool-holding device suitable for cutting a slender axis, which is provided with a chuck. A turning tool-mounting cutting tools-array is fixed at the top surface of the jaw of the chuck; the turning tool-mounting cutting tools-array is provided with a square opening which is used for mounting a turning tool and has the same radial with the chuck; a stop screw for locking the turning tool is arranged on the side wall of the turning tool-mounting cutting tools-array; the stop screw for locking the jaw is arranged on the chuck body of the chuck; a connection chuck is fixed at the bottom surface of the chuck; one side of the connection chuck is provided with a hand lever which can be held on a lathe saddle. The turning tool of the utility model is evenly distributed around the slender axis to be processed; through adjustment, the tool nose of the turning tool is at the same radial cross section. When in process, a plurality of cutters are used for cutting at the same time, and then the generated radial cutting resistance is mutually counteracted, thus the slender axis does not generate bend and deformation when in cutting. The turning tool is a cutting tool and is also used for firmly supporting workpieces, thereby avoiding the workpieces from generating bend and deformation under the action of the gravitation; the processing method has high processing efficiency and high precision.

Description

Be suitable for cutting the tool holder of slender axles

Technical field

The utility model relates to turned part.

Background technology

Processing to workpiece on the lathe is the hilted broadsword cutting, and slender axles are in working angles, and it is subjected to radial cutting force to influence flexural deformation, and is easy to generate vibration, requires very high to operation.Chuck is the annex of lathe, is installed on the headstock, is used for fixing workpiece.On the book of teaching, can find the internal structure of chuck commonly used, " metal working practical basis " book that example is published by publishing house of China University of Geosciences (Wuhan) in August, 2004.Scroll chuck has chuck body and gamp tooth, three claws are separately positioned in three grooves of chuck body, large bevel gear is engaged with three cone pinions, rotate any in three cone pinions, the capital makes the large bevel gear rotation, since the flat thread at its back side just make three claws simultaneously to the center near or withdraw from, to clamp or to unclamp workpiece.

The utility model content

The purpose of this utility model is to propose a kind of simple and convenient tool holder that is suitable for cutting slender axles.

For achieving the above object, the technical solution adopted in the utility model is as follows:

The utlity model has chuck, be fixed with dress cutter blade row on the end face of the claw of chuck, described dress cutter blade row has the square opening that lathe tool is installed with radially consistent being used to of chuck, the sidewall of dress cutter blade row is provided with the screw that ends to the lathe tool locking, chuck chuck body be provided with the screw that ends to claw locking, be fixed with terminal pad on the bottom surface of chuck, a side of terminal pad is provided with the handle that can be clamped on the lathe saddle.

Described chuck is scroll chuck or chuck.

The utility model is evenly distributed in lathe tool around the slender axles to be processed 3 or 4, makes 3 or 4 the point of a knife of lathe tool on same radial section by adjustment.Add the man-hour multitool and cut simultaneously, make the radial cutting force that produces cancel each other, slender axles just can generation flexural deformation when cutting like this.Several is lathe tool that cutting tool has simultaneously been held workpiece again firmly, in order to avoid workpiece flexural deformation under the effect of gravity, this processing method working (machining) efficiency height, precision are good, and can remove from supporting and use centre frame.The utility model can be processed draw ratio and reach 80～100 slender axles.

Description of drawings

For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein

Fig. 1 is the utility model example structure diagrammatic sketch;

Fig. 2 is that the K of Fig. 1 is to view;

Fig. 3 is the A-A cutaway view of Fig. 1.

The specific embodiment

Embodiment 1

Embodiment 1 shown in the accompanying drawing 1～3 has chuck 1, chuck 1 internal structure basic structure is identical with scroll chuck structure commonly used on the textbook, adopt on the chuck 1 four claw 1-1 are set, four claws are separately positioned in four grooves of chuck body, large bevel gear is engaged with four cone pinions, rotates in four cone pinions any, all can make the large bevel gear rotation, the flat thread at its back side just make four claws simultaneously to the center near or withdraw from, to clamp or to unclamp workpiece.Be fixed with dress cutter blade row 2 on the claw 1-1 end face on the chuck 1, dress cutter blade row 2 is symmetrical arranged.Described dress cutter blade row 2 has the square opening that lathe tool 3 is installed with radially consistent being used to of chuck 1, and the sidewall of dress cutter blade row 2 is provided with screwed hole, is connected with an only screw 4 in the screwed hole, locks by ending 4 pairs of lathe tools of a screw.1 chuck body 1-2 of chuck is provided with screwed hole, connects in the screwed hole to end a screw 5, causes claw 1-1 locking by ending 5 pairs of large bevel gear 1-3 lockings of a screw.Be fixed with terminal pad 6 on the bottom surface of chuck 1, a side of terminal pad 6 is provided with the handle 7 that can be clamped on the lathe saddle 8.

Embodiment 2

Omit view, the chuck 1 of present embodiment is a scroll chuck commonly used, and all the other are identical with embodiment 1.

The utility model can be used a bit of sample earlier in actual applications, and the registration coupon external diameter carries out the clamping adjustment of lathe tool.Slender axles one end is clamped by the headstock chuck, and the other end is by the space between the claw of this tool holder chuck, adds the man-hour multitool and cuts simultaneously.

Claims

1, a kind of tool holder that is suitable for cutting slender axles, has chuck (1), it is characterized in that: be fixed with dress cutter blade row (2) on the end face of the claw (1-1) of chuck (1), described dress cutter blade row (2) has with radially consistent being used to of chuck (1) installs the square opening of lathe tool (3), the sidewall of dress cutter blade row (2) is provided with the only screw (4) to the lathe tool locking, the chuck body (1-2) of (1) of chuck is provided with the only screw (5) to claw (1-1) locking, be fixed with terminal pad (6) on the bottom surface of chuck (1), a side of terminal pad (6) is provided with the handle (7) that can be clamped on the lathe saddle (8).
