the utility model provides a universal bounce measuring tool which is suitable for accessory transmission case products, and can be suitable for the bounce measuring requirements of gear shafts with different journals and different measuring ranges by arranging a measuring wall with graded orifice diameter and arm rod length relative to the bounce measuring tool of a gear rotation axis, thereby greatly reducing the manufacturing quantity of tools, reducing the manufacturing cost of the tools, and having the advantages of high measuring efficiency and convenient management.

In order to achieve the purpose, the utility model is realized by adopting the following technical scheme.

The utility model provides a general annex transmission machine casket measuring tool that beats, includes measuring arm and table clamp, measuring arm one end be the extension rod, the other end is the fixed orifices, the table clamp slide to be fixed on the extension rod, the fixed orifices be annular opening structure, the opening part is fixed through screw one to adjust the opening size of measuring arm fixed orifices through screw one.

Further, the meter clamp is of a herringbone structure and comprises two side walls and an inner wall between the two side walls, a meter head clamping hole with different apertures is formed between the two side walls and the inner wall and used for mounting the clamping measuring meter, and a mounting through hole used for mounting the extension rod is formed in the inner wall.

Furthermore, threaded holes perpendicular to the side walls are further formed in the two side walls, and a first screw is arranged in each threaded hole and used for fastening and clamping the measuring meter.

Furthermore, the inner wall is provided with a threaded hole perpendicular to the mounting through hole.

Further, the meter head clamping device further comprises a first bushing and a second bushing, wherein the first bushing and the second bushing are respectively arranged in the two meter head clamping holes.

Furthermore, the first bushing and the second bushing are of open annular structures.

And the second screw is arranged in a threaded hole of which the inner wall is vertical to the installation through hole and is used for fixing the meter clamp on the measuring arm.

The utility model has the beneficial effects that:

the utility model can be suitable for the requirements of measuring the runout of gear shafts with different journals and different measuring ranges by arranging the measuring arm with one end provided with the fixing hole and the other end provided with the extension rod with graded length, thereby greatly reducing the manufacturing quantity of tools and lowering the manufacturing cost of the tools.

Detailed Description

The utility model is used with a gear fixing rod (gear backlash distance measuring or fixing tool). The technical scheme includes that the universal accessory transmission casing runout measuring tool comprises a first screw 1, a third screw 3, a second screw 4, a meter clamp 2, a first bushing 5, a second bushing 6 and a measuring arm 7.

The first screw 1 is used for adjusting the opening size of the fixing hole of the measuring arm 7 and fixing the measuring arm 7 on the gear fixing rod.

The gauge clamp 2 is used for clamping a dial indicator and a dial indicator head, is of a chevron structure and comprises two side walls and an inner wall between the two side walls, and gauge head clamping holes with different apertures are formed between the two side walls and the inner wall and are used for mounting and clamping a measuring gauge so as to ensure the universality of gauge heads with different specifications; 2 gauge outfit centre gripping holes that the aperture is different set up bush one 5, bush two 6 respectively and are used for protecting the appearance quality of gauge outfit centre gripping position in the clamping process. The inner wall is provided with a mounting through hole for mounting on the extension rod, and the extension rod is mounted in the mounting through hole.

And the third screw 3 is used for fixing the watch head on the watch clip 2.

And the second screw 4 is used for fixing the meter clamp 2 on the measuring arm 7.

The measuring arm 7 is used for supporting the meter clamp 2 and the meter head, and is provided with graded fixing holes and extension rod lengths (the grade can be increased according to the use condition) so as to adapt to different gear fixing rods and measuring ranges and achieve universality.

When the universal accessory casing runout measuring tool is used, according to the diameter of a gear fixing rod and the runout measuring circumferential range, a measuring arm 7 with a proper grade is selected and is fixed by a screw I1, a gauge clamp 2 is fixed on the measuring arm 7 by a screw II 4 at the other end, a gauge head with proper precision is selected, and the gauge head is fixed on the gauge clamp 2 by a screw III 3. When in measurement, the pointer end of the gauge head is put on the corresponding measuring surface of the part, the maximum value and the minimum value on the dial are read by rotating the fixed rod for 1 week, and the difference is the jumping value.

The utility model has been described above with reference to the accompanying drawings, it is obvious that the utility model is not limited to the specific implementation in the above-described manner, and it is within the scope of the utility model to apply the inventive concept and solution to other applications without substantial modification.
