[0025] In order to more clearly and explicitly illustrate the specific implementation purpose and implementation method of the utility model, the technical solution of the utility model will be fully described below. The described embodiment is a part of the embodiment of the utility model, not all the embodiments. Without making creative work, all other embodiments based on the embodiment described in the utility model belong to the protection scope of the utility model.

[0026] The utility model discloses a double-station fixture for horizontal processing of cylinder heads. Figure 1 As shown, the clamp can clamp two metal parts at the same time and cooperate with machining equipment to perform double-station processing. The double-station can perform one processing or two processing, which improves the efficiency of machining. Specifically, this embodiment includes a base 1, which is a metal plate. The base 1 is fixed on a rotating table. A support frame 2 is installed on the base 1. Specifically, the support frame 2 is "H"-shaped, and a lifting ring 6 is installed on the upper end of the support frame 2 to facilitate lifting and transferring the support frame 2. The support frame 2 is fixed to the base 1 by welding.

[0027] Both ends of the support frame 2 of this embodiment are equipped with clamping assemblies. Specifically, the clamping assembly includes a lateral clamping portion 3, and the lateral clamping portion 3 includes a plurality of support columns 31 installed on the support frame 2. The support columns 31 are arranged at intervals, that is, the support columns 31 are arranged at intervals in the vertical direction and the horizontal direction. For example, in this embodiment, four support columns 31 are installed on one side of the support frame 2, and four support columns 31 are installed on the other side of the support frame 2. The support column 31 has a screw rod 32, and the screw rod 32 has a clamping claw 33. The clamping claw 33 and the screw rod 32 are clearance-matched. A locking nut 34 is threadedly installed on the screw rod 32, and the locking nut 34 presses the clamping claw 33. After being pressed, the clamping claw 33 is pressed from both sides of the metal part.

[0028] In addition, the clamping assembly includes an end clamping portion 4, which includes an end bearing frame 41. The end bearing frame 41 has a threaded hole. A first adjusting bolt 42 is installed in the threaded hole of the end bearing frame 41. The big head end of the first adjusting bolt 42 is arranged below the end bearing frame 41. The first adjusting bolt 42 is arranged vertically. The clamping assembly also includes a center clamping portion 5. The center clamping portion 5 includes a center bearing frame 51. The side of the center bearing frame 51 has a threaded hole. The threaded holes on the side of the center bearing frame 51 are all installed with second adjusting bolts 52. In addition, spare adjusting bolts 53 are installed in redundant threaded holes, which are used when the second adjusting bolts 52 cannot meet the clamping requirements. The second adjusting bolts 52 are arranged horizontally.

[0029] According to the specific structure in the above embodiment, the working process is further described below:

[0030] The sealing end face of the cylinder head faces the support frame 2. By tightening the locking nut 34, part of the clamping jaws 33 are coplanar and in contact with the sealing end face of the cylinder head, and the inner wall of the cylinder head is in contact with the side end face of the end support frame 41 and the small end of the first adjusting bolt 42; by rotating the first adjusting bolt 42, the height of the cylinder head is adjusted; by tightening the second adjusting bolt 52, the extension of the cylinder head is clamped; by tightening the locking nut 34, the other part of the clamping jaws 33 presses the cylinder head. After the cylinder head is clamped and fastened, as the rotating table rotates, the two cylinder heads can be processed in double positions at the same time.
