[0028] Refer to Figure 1 For an embodiment of a pneumatic fixture with an elongated hole for an engine mount of the present utility model,

[0029] It includes a base 1, and a first positioning component 2, a second positioning component 3, a third positioning component 4, a fourth positioning component 5, and a fifth positioning component 6 are arranged on the base 1;

[0030] The first positioning component 2 includes a positioning block 21 and a positioning plate 22 arranged on the base 1. The end faces of the positioning block 21 adjacent to the positioning plate 22 are parallel and have a positioning gap 23;

[0031] The second positioning component 3 includes a positioning hole 31 penetrating through the positioning plate 22 and a positioning pin 32 inserted into the positioning hole 31;

[0032] The third positioning component 4 includes a mounting plate 41 arranged on the base 1 and a cylinder 42 arranged on one side of the mounting plate 41. A compression nut is arranged at the piston end of the cylinder 42, and the piston end of the cylinder 42 extends and retracts in the horizontal direction;

[0033] The fourth positioning component 5 is composed of a corner cylinder 51 and a pressing plate 52 arranged at the piston end of the corner cylinder 51. The piston end of the corner cylinder 51 extends and retracts in the vertical direction;

[0034] The fifth positioning component 6 includes a threaded hole 61 arranged on the upper end face of the mounting plate 41, and a support pin 62 is threadedly connected in the threaded hole 61.

[0035] The present device is a fixture for drilling holes in the engine support. The shape of the engine support is similar to a right-angle plate. For the convenience of description, the engine support is defined as consisting of a plate A and a plate B. Before drilling, the plate A of the engine support needs to be vertically placed in the positioning gap 23 of the first positioning component 2 in the present fixture, and then the positioning pin 32 in the second positioning component 3 is inserted into the hole of the engine support plate A through the positioning hole 31. Then, the cylinder 42 in the third positioning component 4 is started, and the clamping nut at the piston end of the cylinder 42 is pressed on the plate A of the engine support, and the plate A of the engine support is pressed against the positioning plate 22.

[0036] Then, the rotation cylinder 51 of the fourth positioning assembly 5 is operated, the rotation cylinder 51 rises, and then drives the pressure plate 52 to rotate to above the plate B of the engine support, and then the rotation cylinder 51 contracts to press the pressure plate 52 on the upper end surface of the plate B; at this time, since the plate B is subjected to the downward pressure applied by the pressure plate 52, the support nail 62 in the fifth positioning assembly 6 works, and the support nail 62 is against the lower end surface of the plate B, providing an upward support force for the plate B, and cooperates with the downward pressure applied by the pressure plate 52 to play a role in positioning the plate B;

[0037] The positioning of the engine mount is now complete.

[0038] In this device, the clamping nut at the piston end of the cylinder 42 will press on the plate A of the engine support to form a vertical positioning surface, clamping the plate A of the engine support. The pressure plate 52 driven by the corner cylinder 51 combines with the upper end surface of the support pin 62 to form a horizontal positioning surface, clamping the plate B of the engine support; with this arrangement, the stable positioning of the engine support can be achieved.

[0039] The second positioning assembly 3 in the device further comprises a positioning guide sleeve 33 arranged in the positioning hole 31, and the positioning pin 32 is inserted into the positioning guide sleeve 33; the positioning guide sleeve 33 serves to facilitate the positioning pin 32 to be inserted into the hole in the engine support plate A through the positioning guide sleeve 33.

[0040] A reference block 24 is further provided on the side of the positioning plate 22 close to the positioning block 21 . There are two reference blocks 24 , which are symmetrically arranged on the side of the positioning block 21 .

[0041] The reference block 24 of the device is designed according to the shape of the engine support. A boss is provided on the vertical side of the plate A of the engine support, and the reference surface of the reference block 24 matches the boss.

[0042] An inclined surface 25 is also provided on the side of the positioning block 21 close to the positioning plate 22 .

[0043] The design of the inclined surface 25 can facilitate the insertion of the plate A of the engine mount into the positioning gap 23 .

[0044] An installation groove 7 is further provided on the upper end surface of the positioning block 21, and a part of the air cylinder 42 is placed in the installation groove 7. Since this device is an integrated fixture, the first positioning component 2, the second positioning component 3, the third positioning component 4, the fourth positioning component 5, and the fifth positioning component 6 are all integrated together. In order to reduce the volume of the entire fixture, an installation groove 7 is dug on the upper end surface of the positioning block 21. The purpose is to reduce the installation height of the air cylinder 42, thereby reducing the height of the entire fixture, shrinking the volume of the entire fixture, and at the same time reducing the cost of the entire fixture.

[0045] The fourth positioning component 5 further includes an installation base 53. The corner air cylinder 51 is fixed to the installation base 53 by screws, and the installation base 53 is arranged on one side of the installation plate 41.

[0046] The installation base 53 is a general installation structure for the corner air cylinder 51 and is a structure often used in the field. The specific function is to install the corner air cylinder 51, but the height of the installation base 53 can be adjusted according to the piston stroke length of the corner air cylinder 51.

[0047] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creation of the present utility model.
