DETAILED DESCRIPTION

[0039] A clamp for quick assembly and disassembly of a gearbox housing, such as Figure 1 As shown, it includes a vertically arranged fixture mounting plate 1 and a plurality of clamp assemblies 2 arranged on the fixture mounting plate 1, at least one nylon column 3, a plurality of elastic positioning pins 4, a plurality of fixed support assemblies 5 and an adjustable support block 6;

[0040] The nylon column 3 is compatible with the bearing hole on the shell. The nylon column 3 passes through the bearing hole to fix the shell on the fixture. The diameter of the nylon column 3 is 3 to 5 mm smaller than the aperture of the bearing hole on the shell, which can effectively avoid bumping against the shell during installation. When hoisting the shell, the middle bearing hole of the shell can be inserted into the nylon column 3 for preliminary positioning.

[0041] like Figure 4As shown, a plurality of elastic positioning pins 4 are matched with a plurality of precast holes on the shell, and are used to precisely adjust and position the shell, thereby improving the accuracy of the positioning of the shell.

[0042] The adjustable support block 6 is arranged near the lower edge of the fixture mounting plate 1, and its position is higher than the clamp assembly 2 arranged near the lower edge of the fixture mounting plate 1, and is used to adjust the installation height of the housing. The adjustable support block 6 can be used as a temporary fulcrum. During the process of loading and unloading workpieces, the housing can be first moved to the temporary fulcrum, that is, the adjustable support block 6, and then the housing can be moved from the temporary fulcrum to the nylon column 3 for preliminary positioning; the housing is supported and positioned by the nylon column 3 and the adjustable support block 6, which can effectively reduce the labor intensity during the loading and unloading process, save time and labor, and effectively improve the efficiency of disassembly and assembly of the housing.

[0043] like Figure 2 and 3 As shown, the adjustable support block 6 includes a support block mounting seat 13 and a support block 14 arranged on the support block mounting seat 13, a second adjustment slot 15 is opened on the support block mounting seat 13, the support block mounting seat 13 and the fixture mounting plate 1 are fixed by a positioning screw passing through the second adjustment slot 15, and the installation position of the adjustable support block 6 is adjusted by changing the installation position of the positioning screw on the second adjustment slot 15.

[0044] A plurality of clamp assemblies 2 are evenly distributed on the fixture mounting plate 1, and are used to clamp the edge of the shell, pre-tighten the shell, and make it evenly stressed. The distribution position of the clamp assemblies 2 can also be adjusted according to the specific shape of the shell; Figure 5 and 6 As shown, the clamp assembly 2 includes a clamp mounting base 7 and a clamp 8 fixed on the clamp mounting base 7. The clamp mounting base 7 is provided with a first adjustment slot 9. The clamp mounting base 7 and the clamp mounting plate 1 are fixed by a positioning screw passing through the first adjustment slot 9. The installation position of the clamp assembly 2 can be adjusted by changing the installation position of the positioning screw on the first adjustment slot 9.

[0045] The support block 14 of the adjustable support block 6 and the clamp 8 are both provided with nylon gaskets to prevent the shell from bumping, effectively reducing the scrap rate of the shell, saving production resources and reducing production costs. The clamp assembly 2 and the adjustable support block 6 are provided with adjustment slots. By changing the installation position of the positioning bolts on the adjustment slots and adjusting the setting positions of the clamp assembly 2 and the adjustable support block 6, the shells with different sizes can be accurately positioned to improve the stability of the shell.

[0046] like Figure 7As shown, a plurality of fixed support components 5 are arranged corresponding to the plane on the edge of the shell, and are used for surface supporting and positioning the edge of the shell; the fixed support component 5 includes a support mounting plate 10 and a support column 11, the support mounting plate 10 is fixed to the fixture mounting plate 1 by screws, one end of the support column 11 is connected to the support mounting plate 10, and the other end of the support column 11 is a support end face, corresponding to the plane on the edge of the shell, and is used for surface supporting and positioning the edge of the shell.

[0047] A corresponding pressing plate 16 is provided on the fixture mounting plate 1 near each fixed support assembly 5. Figure 8 As shown, the pressure plate assembly 16 includes a pressure plate mounting seat 17 and a pressure plate 18 arranged on the fixture mounting plate 1, one end of the pressure plate 18 is connected to the pressure plate mounting seat 17, and the other end is arranged opposite to the supporting end surface of the support column 11, and there is a gap between the two, and the shell is located in the gap between the two. The pressure plate 18 of the fixed support assembly 5 and the pressure plate assembly 16 cooperates with the external hydraulic device to clamp the shell.

[0048] The support column 11 can be replaced with an adjustable support column. When the shell blank has a large deformation deviation, it can be positioned and supported by the adjustable support column. It can be precisely adjusted according to the size difference of the shell to change its support height, which effectively expands the application range of the clamp and ensures the stability and reliability of the clamp when fixing the shell.

[0052] Two elastic positioning pins 4 are arranged on the fixture mounting plate 1, and the two elastic positioning pins 4 correspond to the two precast holes on the front shell. When the front shell is basically installed on the fixture, the front shell is accurately positioned by the two elastic positioning pins 4. When the apertures of the precast holes on the front shells of different batches vary, the positions of the elastic positioning pins 4 can be adjusted to allow the front shell to be accurately positioned.

[0053] Three clamp assemblies 2 are also arranged on the clamp mounting plate 1, one of which is arranged near the upper edge of the clamp mounting plate 1, and the other two are arranged near the lower edge of the clamp mounting plate 1; after the front shell reaches the target positioning position, the three clamp assemblies 2 cooperate with each other to clamp the front shell so that the force is evenly applied and the front shell is kept in the current position without moving.

[0054] Three fixed support assemblies 5 are arranged at positions on the fixture mounting plate 1 corresponding to the plane on the shell, and a corresponding pressure plate assembly 16 is arranged at the position of each fixed support assembly 5. The pressure plate 18 on the pressure plate assembly 16 is arranged opposite to the support column 11 on the fixed support assembly 5, and there is a gap between the two.
