Any positioning seat is arranged adjacent to any support, and the other positioning seat is positioned between the other two supports, so that the distance between the two positioning seats is far and uniformly distributed, and the positioning precision of the transmission shell is favorably ensured.
In the above-described transmission case clamp, the positioning seat top surface is higher than the top surface of the support. The locating hole of derailleur casing can adopt the step hole molding, can make the locating pin and the aperture cooperation in the locating hole like this, and the positioning seat can cooperate with locating hole and the step face in the locating hole, improves positioning accuracy, through setting up the top surface of positioning seat and being higher than the top surface of support, can guarantee like this that positioning seat and support can not make the production interference at the assembly.
In the above-mentioned clamp for the transmission case, the upper surface of the depression bar has a relief surface extending obliquely downward to the outer end surface of the depression bar. The upper surface of the pressing strip is provided with the abdicating surface which extends downwards to the outer end surface of the pressing strip in an inclined mode, so that the size of the outer end of the pressing strip is reduced, the requirement of the pressing strip on the structure of the outer peripheral surface of the transmission shell can be further reduced, and the applicability is guaranteed.
In the clamp of the transmission shell, the rotary cylinder, the support and the positioning seat are detachably connected with the base through bolts. Through setting up revolving cylinder, support and positioning seat and all can dismantling through the bolt and be connected with the base, be convenient for like this according to the derailleur casing dismouting of different models to the position one that the difference satisfies the clamp dress needs.
Compared with the prior art, the utility model has the advantages as follows:
this transmission housing's anchor clamps is through the revolving cylinder who sets up vertical arrangement more than three on the base, connect the layering that the level extends at revolving cylinder's top, make revolving cylinder can drive the layering horizontal swing to vertical just right and form the cooperation space with the top surface of preparation between the two, after placing transmission housing to support like this, revolving cylinder can drive the layering along the horizontal direction swing and make the layering and support cooperation make the outer fringe of transmission housing be located the cooperation space thereby to the vertical formation stable positioning clamp of transmission housing, guarantee the processing effect, and the layering can reduce the overall arrangement requirement to transmission housing vertical structure owing to be horizontal swing, do benefit to and improve anchor clamps suitability.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the fixture of the transmission housing comprises a base 1, three supports 2 used for supporting the housing and more than two positioning seats 3 are fixedly arranged on the base 1, positioning pins 4 vertically arranged are inserted in the centers of the positioning seats 3, the supports 2 are circumferentially arranged around the base 1 at intervals, three vertically arranged rotary cylinders 5 are further fixedly arranged on the base 1, pressing strips 6 extending along the horizontal direction are connected to the tops of the rotary cylinders 5, and when the rotary cylinders 5 drive the pressing strips 6 to horizontally swing, the lower surfaces of the pressing strips 6 are vertically opposite to the top surfaces of the corresponding supports 2, and a matching space 7 is formed between the two surfaces. Base 1 sets firmly three above support 2 and can form stable support to derailleur casing one end edge along circumference on base 1 for pressing from both sides the platform of dress derailleur casing, thereby the locating pin 4 in the locating seat 3 more than two can guarantee the derailleur casing at the stable accuracy of horizontal direction position with the vertical cooperation of locating hole on the derailleur casing. Through the revolving cylinder 5 that sets up vertical arrangement more than three on base 1, layering 6 that the level extends is connected at revolving cylinder 5's top, make revolving cylinder 5 can drive layering 6 horizontal swing to vertical just right and form cooperation space 7 between the two with the top surface of preparation, after placing derailleur casing to support 2 like this, revolving cylinder 5 can drive layering 6 along the horizontal direction swing and make layering 6 and support 2 cooperation make the outer fringe of derailleur casing be located cooperation space 7 thereby to the vertical stable positioning clamp that forms of derailleur casing, guarantee the result of working, layering 6 can reduce the overall arrangement requirement to derailleur casing vertical structure owing to be horizontal swing, do benefit to the improvement anchor clamps suitability. Any one positioning seat 3 is arranged adjacent to any one support 2, and the other positioning seat 3 is positioned between the other two supports 2. Any positioning seat 3 is arranged adjacent to any support 2, and the other positioning seat 3 is positioned between the other two supports 2, so that the two positioning seats 3 are far away from each other and are uniformly distributed, and the positioning precision of the transmission shell is favorably ensured. The top surface of the positioning seat 3 is higher than that of the support 2. The locating hole of derailleur casing can adopt the step hole molding, can make locating pin 4 and the aperture cooperation in the locating hole like this, and positioning seat 3 can improve positioning accuracy with the locating hole and the step face cooperation in the locating hole, through setting up 3 top surfaces of positioning seat and being higher than the top surface of support 2, can guarantee like this that positioning seat 3 and support 2 can not make the production interference in the assembly. The upper surface of the bead 6 has an escape surface 61 extending obliquely downward to the outer end surface of the bead 6. The receding surface 61 which extends to the outer end surface of the pressing strip 6 obliquely downwards is arranged on the upper surface of the pressing strip 6, so that the size of the outer end of the pressing strip 6 is reduced, the requirement of the pressing strip 6 on the structure of the outer peripheral surface of the transmission shell can be further reduced, and the applicability is ensured. The rotary cylinder 5, the support 2 and the positioning seat 3 are detachably connected with the base 1 through bolts. Through setting up revolving cylinder 5, support 2 and positioning seat 3 and all can dismantle with base 1 through the bolt and be connected, be convenient for like this according to the derailleur casing dismouting of different models to the position one of difference and satisfy different double-layered dress needs.
