Embodiment 1

[0033] The invention discloses a semi-automatic force compensation clamping device, which is installed on the guide rail of a grinding machine, such as figure 1 , image 3 As shown, it includes a U-shaped limit block 1, a guide rod 2 and a fixed slider 3 installed on the guide rail of the grinding machine; one end of the guide rod 2 is installed on one side of the fixed slider 3, and the guide rod 2 is away from the fixed One end of the slider 3 is connected with a U-shaped limit block; the end of the U-shaped limit block 1 away from the guide rod 2 is provided with a U-shaped groove 11 .

[0034] The fixed slider 3 is detachably connected to the guide rail of the grinder and can be fixed at different positions on the guide rail of the grinder. When processing different parts of the ultra-long-diameter cutter 100, by adjusting the different positions of the fixed slider 3 on the guide rail of the grinding machine, the pressing task along different parts of the super-long-diam...

Embodiment 2

[0038] This embodiment is improved on the basis of Embodiment 1, and the improvement is that: the guide rod 2 includes a guide rod 21 and a mounting seat 22 arranged at one end of the guide rod 21, and the mounting seat 22 is far away from the guide rod 21 A groove 221 is provided on one side of the U-shaped limiting block 1 , and the end of the U-shaped limiting block 1 away from the U-shaped groove 11 is inserted into the groove 221 and the groove 221 is an interference fit. The U-shaped U-shaped limiting block is detachably connected to the installation groove 12. If the diameters of different batches of ultra-long-diameter tools 100 are different, different U-shaped limiting blocks 1 can be replaced to adapt to the diameter of the ultra-long-diameter tool 100. The arc-shaped contact between the diameter and the U-shaped groove 11 realizes the pressing and uniform and stable force of the diameters of the ultra-long diameter cutters 100 of different diameters and the U-shaped...

Embodiment 3

[0041] This embodiment is improved on the basis of Embodiment 2, and its improvements are as follows: figure 2 As shown, the distance between the U-shaped limiting block 1 and the fixed slider 3 can be adjusted to adjust the position of the U-shaped limiting block 1, so that the U-shaped limiting block 1 can press the super-long-diameter tool 100 without Moving the positions of the grinding wheel 200 and the guide rail of the grinding machine can ensure that the ultra-long-diameter tool 100 is pressed against the grinding wheel 200 . The distance adjustment between the U-shaped limit block 1 and the fixed slider 3 can be realized by the following structure.

[0042] One end of the U-shaped limit block 1 connected to the guide rod 2 is provided with a mounting groove 12, the inner surface of the installation groove 12 is provided with an internal thread, and the side of the end of the guide rod 2 away from the fixed slider 3 is provided with an external thread , the U-shaped ...

Abstract

The invention discloses a semi-automatic force bearing compensation clamping device. The semi-automatic force bearing compensation clamping device is suitable for outer circle precision grinding machining of an extra-long diameter cutter with the length-diameter ratio being not less than 20 and installed on a grinding machine guide rail and comprises a U-shaped position-limiting block, a guide rodand a fixed sliding block installed on the grinding machine guide rail, wherein one end of the guide rod is installed to one side of the fixed sliding block, the end, away from the fixed sliding block, of the guide rod is connected with the U-shaped position-limiting block, and the end, away from the guide rod, of the U-shaped position-limiting block is provided with a U-shaped slot. According tothe semi-automatic force bearing compensation clamping device disclosed by the invention, the diameter of the extra-long diameter cutter is compressed through the U-shaped position-limiting block, stable and even force bearing of the U-shaped position-limiting block is realized, and most grinding pressure can be counteracted, manual holding a bamboo plate by hands to jack the diameter of the extra-long diameter cutter is not needed, and the problem that imbalance force applying in operations of workers is prone to causing uneven single side force bearing on the diameter of the extra-long diameter cutter to generate deformation in the machining process to cause poor cutter outer circle size and insufficient outer circle roundness is avoided.

Description

technical field [0001] The invention relates to the technical field of precision grinding and clamping devices for cutting tools, in particular to a semi-automatic force compensation clamping device. Background technique [0002] Ultra-long-diameter cutting tools are widely used in the aviation field and are important tools in the assembly process of aircraft parts. The accuracy and quality of many holes in an aircraft is closely related to the quality of the extra long diameter tool. Many times extra-long diameter cutters are used as the last tool in the aircraft hole making process. The quality of ultra-long diameter tools directly affects the quality of holes on aircraft parts. However, the processing of ultra-long-diameter tools is extremely difficult. On the one hand, the precision of the tool requires high tolerances on the outer diameter of the cutting part, the guide part of the shank, the circular runout tolerance, and the straightness tolerance requirements are v...
