[0026] like Figure 1-4As shown, the utility model provides an adjustment jig for a cylinder clamp, which has a first positioning unit and a second positioning unit fixed relative to the first positioning unit. The first positioning unit has a reference line that can coincide with the center line of the circle surrounded by all the claw bodies 520 of the cylinder clamp and / or the axis line of the outer arc surface of the cylinder 510 of the cylinder clamp. Specifically, the reference line can be the axis line of a cylinder, a circular hole, or the center line of the circle corresponding to the arc surface. Specifically, when the reference line coincides with the axis line of the outer arc surface, the axis line of the outer arc surface is the center line of the circle surrounded by all the claw bodies 520. Usually, the center line of the circle surrounded by all the claw bodies 520 coincides with the axis line of the outer arc surface of the cylinder 510 of the cylinder clamp. Therefore, it is only necessary to keep the reference line coincident with the axis line of the outer arc surface of the cylinder 510. The second positioning unit is used to cooperate with the claw body 520 to locate the position of the claw body 520.

[0027] When in use, the reference line is coincident with the center line of the circle enclosed by all the claw bodies 520 or the axis center line of the outer arc surface of the cylinder 510 of the cylinder clamp. Since the relative position of the second positioning unit and the first positioning unit is fixed, the relative position of the second positioning unit and the reference line is fixed. By making each claw body 520 correspond to the second positioning unit in turn, it can be ensured that all the claw bodies 520 are located in the same circle, thereby achieving the purpose of ensuring the running distance of all the claw bodies 520.

[0028] In one embodiment, the first positioning unit includes a reference seat 100, and the reference seat 100 has a first positioning surface 110, and the first positioning surface 110 is in an arc shape, so that the first positioning surface 110 has the above-mentioned reference line, that is, the center line of the circle corresponding to the arc surface. And the first positioning surface 110 is adapted to the outer arc surface. When in use, the first positioning surface 110 is fitted with the outer arc surface of the cylinder 510 to ensure that the reference line coincides with the axis center line of the outer arc surface of the cylinder 510. The second positioning unit includes a reference block 200, and the reference block 200 has a second positioning surface 210 that matches the claw body 520, and the reference block 200 is fixedly set on the reference seat 100.

[0029] When in use, first fit the first positioning surface 110 with the outer arc surface of the cylinder 510, and then fit one end of the claw body 520 with the second positioning surface 210 to achieve the purpose of determining the position of the claw body 520. All claw bodies 520 are fit with the second positioning surface 210 in turn to achieve the purpose of determining the position of all claw bodies 520. The operation is simple and easy to use.

[0030] Preferably, the reference block 200 is provided with a boss, and the second positioning surface 210 is provided on a side of the boss facing the reference line (ie, the center line of the circle corresponding to the arc contour line of the first reference surface 110 ).

[0031] In one embodiment, the central angle corresponding to the arc contour line of the first positioning surface 110 is α, wherein 90°≤α≤180°, so that 90°≤α≤180° is achieved, thereby facilitating the first positioning surface 110 to be buckled on the outer arc surface of the cylinder 510 and fit with the outer arc surface, and the first positioning surface 110 corresponding to the angle range is more accurate and convenient for positioning the claw body 520 than the first positioning surface 110 corresponding to the central angle less than 90°.

[0032] In one embodiment, the second positioning surface 210 has a first permanent magnet 300 on the fixing collar. When in use, the first electromagnet attracts the claw body 520 that needs to be adjusted, thereby facilitating the tightening of the bolts used to fix the claw body 520, thereby further improving the adjustment efficiency.

[0033] In one embodiment, a boss 120 is provided on one side of the first positioning surface 110 facing the second positioning surface 210, and a plurality of second permanent magnets 400 are fixedly embedded on the boss 120, and the plurality of second permanent magnets 400 are sequentially arranged at intervals around the reference line. By providing the second permanent magnet 400, the other claws 520 are attracted by the second permanent magnet 400, thereby achieving the purpose of facilitating the fixing of the fixture. At the same time, the magnetic attraction of the second permanent magnet 400 can attract the corresponding fixing bolts, thereby achieving the purpose of facilitating the placement and finding of the bolts, and further achieving the purpose of further improving the adjustment efficiency.

[0034] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
