Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a clamping boring device and a clamping boring structure. Background Technology

[0002] Horizontal CNC lathes achieve the machining of workpiece inner holes by installing a boring tool holder on the tool post. The original structure usually involved installing the boring tool holder on the tool post with a tool clamping screw, then inserting the boring bar into the hole of the boring tool holder, and finally tightening the boring bar with an adjusting screw.

[0003] In traditional techniques, the contact rigidity of the boring bar and the boring bar holder hole is limited, and they are only tightened and fixed by 2-4 screws. The overall rigidity is poor, which makes it easy to cause chatter when machining deep holes with a large length-to-diameter ratio, affecting the movement performance of the boring bar.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / as well" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] The following describes the embodiments in conjunction with the appendix. Figure 1-2 This utility model will be described in further detail.

[0020] A clamping boring device includes a base 1, a frame 2, a tool holder 3, and a leveling component 5.

[0021] The frame 2 includes a first interlayer 21 and a second interlayer 22, which are spaced apart. Specifically, in this embodiment, the frame 2 is a vertical four-position tool holder. The frame 2 also includes a tool pressing screw 23 and a locking motor 24. The tool pressing screw 23 and the locking motor 24 are installed in the first interlayer 21, and the output end of the locking motor 24 is connected to the second interlayer 22.

[0022] The tool holder 3 includes a clamping part 31, a mating part 32, and a connecting part 33. The mating part 32 and the connecting part 33 are located on both sides of the clamping part 31. Specifically, the clamping part 31, the mating part 32, and the connecting part 33 are integrally formed. The clamping part 31 is C-shaped, and the mating part 32 and the connecting part 33 are arranged perpendicular to each other. The clamping part 31 is provided with a mounting hole 311 and a boring tool clamping screw 312. The boring tool clamping screw 312 is installed at the C-shaped opening of the clamping part 31. The mating part 32 is provided with a clearance groove 321. The connecting part 33 is provided with a fixing screw 331.

[0023] The leveling component 5 includes a strip 51, a strip ejector nut 52, and a guide rail soft strip 53. The strip ejector nut 52 and the strip 51 are threaded together. The guide rail soft strip 53 is pasted to the bottom of the strip 51. The bottom of the guide rail soft strip 53 is manually ground to increase the contact rate of the contact surface, so that it is more tightly in contact with the table surface, thereby making the leveling component 5 more stable when supporting the knife holder 3.

[0024] A clamping boring structure includes the above-mentioned clamping boring device and boring tool 4.

[0025] A connection relationship for a clamping boring structure: The frame 2 is mounted on the base 1. The mating part 32 of the tool holder 3 is installed between the first interlayer 21 and the second interlayer 22. The tool clamping screw 23 presses against the mating part 32 to fix the mating part 32. The clearance groove 321 avoids the locking motor 24. The connecting part 33 is fixedly connected to the base 1 by the fixing screw 331. The boring tool 4 is installed in the mounting hole 311 of the clamping part 31. The boring tool clamping screw 312 locks the boring tool 4. The insert 51 is installed at the bottom of the connecting part 33. The insert pushes out the nut 52 to press against the connecting part 33. The working principle of a clamping boring structure: The base 1 is fixed on the saddle of the CNC machine tool. The insert 51 and guide rail soft belt 53 at the bottom of the connecting part 33 are used to level the device and prevent it from being suspended, and to support the tool holder 3, thereby improving the dynamic performance of the device and reducing vibration. The clamping part 31 is set as a C-shaped structure. By adjusting the boring tool clamping screw 312, the C-shaped clamping part 31 is deformed, which increases the contact rate between the boring tool 4 and the clamping part 31, thereby improving the clamping rigidity.

[0026] The advantages of this utility model are: By using the C-shaped clamping structure of the tool holder 3, the contact method between the boring tool 4 and the tool holder 3 is changed, thereby increasing the contact rate between the boring tool 4 and the tool holder 3 and thus improving the clamping rigidity. In addition, the leveling component 5 is added to support the tool holder 3 and improve the stability of the tool holder 3.

[0027] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
