[0018] The utility model is further illustrated below with reference to the drawings:

[0019] As Figs. 1 to 4 The utility model discloses an electron beam welding frock for fixing straight -through hole part 4 and special -shaped hole part 3, including special -shaped hole locking assembly 1 and straight -through hole locking assembly 2, special -shaped hole locking assembly 1 includes integrative first pressure block 11, outer connecting arm 12, inner connecting arm 13 and connecting block 14, first pressure block 11 is fixed in the right -hand end of outer connecting arm 12 and is equipped with with special -shaped hole part 3 the first pressure surface 111 of resistance and touch, the right end is fixed in the left -hand end of outer connecting arm 12 in inner connecting arm 13, and the left -hand end is equipped with screw hole 141 in connecting block 14's left end, and straight -through hole locking assembly 2 includes integrative second pressure block 21 and connecting column 22, and the right end is equipped with second pressure surface 211 in second pressure block 21, and connecting column 22 is inserted in the hole of straight -through hole part 4, and the left -hand end is fixed in the right -hand end of second pressure block 21 in connecting column 22, and the left -hand end is equipped with the screw of connecting column 22 and is connected with screw hole 141.

[0020] Through the electron beam welding frock of the design, can fix straight -through hole part 4 with special -shaped hole part 3, when using, first, the inner connecting arm 13 on special -shaped hole locking assembly 1 is inserted into the hole position of special -shaped hole part 3, and connecting column 22 on straight -through hole locking assembly 2 is inserted into the hole position of straight -through hole part 4, then gradually the right -hand end of connecting column 22 is screwed into screw hole 141, at this time, special -shaped hole part 3 and straight -through hole part 4 are located between first pressure surface 111 and second pressure surface 211, continue to screw connecting column 22 into screw hole 141, and adjust the position of first pressure block 11, make first pressure surface 111 correspond to the plane of special -shaped hole part 3, until first pressure block 11 and second pressure block 21 press special -shaped hole part 3 and straight -through hole part 4, then complete the fixing between the two, install the fixed special -shaped hole part 3 and straight -through hole part 4 on the welding equipment, can the contact surface of part is welded by electron beam. The advantage of the design is that straight -through hole part 4 and special -shaped hole part 3 can be fixed, and the peripheral space of the part is not occupied, so that the welding equipment can weld the whole periphery of the part.

[0021] The first pressure block 11 corresponds to the central axis of connecting column 22, when the middle part of special -shaped hole part 3 has no larger plane, first pressure block 11 can be selected and pressed on the outer edge plane of the part, if the middle part of special -shaped hole part 3 has a larger plane, preferably, first pressure block 11 is arranged on the central axis of connecting column 22, and first pressure block 11 is pressed on the plane of the middle part of the part, so that the first pressure plane and the second pressure plane are on the central axis of connecting column 22, so that the pressure between the two groups of parts is uniform and is not easy to be pressed off or pressed deformed.

[0022] The through hole locking assembly 2 adopts a bolt, the head of the bolt is the second pressing block 21, and the tail of the bolt is the connecting column 22. The bolt is a standard product, and the cost is low. For the scene that the left end hole position of the through hole part 4 has a large plane, directly adopting the bolt is conducive to reducing the cost.

[0023] In the design, the gusset plate is further included, the gusset plate is sleeved on the connecting column 22 and abuts against the through hole part 4 at the right end, and the second pressing surface 211 of the second pressing block 21 abuts against the left end of the gusset plate. When the middle hole position of the through hole part 4 is large, the gusset plate can be arranged, so that the contact surface of the second pressing block 21 and the through hole part 4 is indirectly increased, thereby obtaining a stable contact effect.

[0024] One end of the second pressing block 21 corresponds to the central axis of the connecting column 22, and the other end of the second pressing block 21 is outside the central axis of the connecting column 22 and is provided with the second pressing surface 211. When the middle part of the through hole part 4 does not have a large plane, the outer end of the second pressing block 21 can also be arranged outside the central axis of the connecting column 22, so that the plane at the outer edge of the through hole part 4 is pressed to achieve the pressing.

[0025] The above is not intended to limit the technical scope of the present application in any way. Any modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments still belongs to the technical scope of the present application.
