[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 3 , a telescopic fixture for machining a turbocharger housing, including a lower positioning plate 1 and an upper positioning plate 11. A set of grooves are respectively opened on the opposite sides of the lower positioning plate 1 and the upper positioning plate 11. A set of processing ports are respectively penetrated through the opposite sides of the two sets of grooves. A fixing component is placed in the grooves. Among them: Guide holes are uniformly penetrated through the top of the upper positioning plate 11. A set of mounting holes are respectively penetrated through the left and right sides of the top of the upper positioning plate 11. A clamping component is placed in the mounting holes. Guide rods 12 are uniformly and fixedly arranged on the top of the lower positioning plate 1. The guide rods 12 are slidably arranged in the guide holes to assist the stable up and down movement of the upper positioning plate 11 through the guide rods 12. The clamping component includes screws 13. The two screws 13 are uniformly and fixedly arranged on the top of the lower positioning plate 1. The top of the screw 13 penetrates through the mounting hole of the upper positioning plate 11 and is screwed with a nut 15. A spring 14 is placed on the outer circle of the screw 13. The two springs 14 are uniformly and fixedly arranged on the top of the lower positioning plate 1. The upper positioning plate 11 is placed on the top of the spring 14. The bottom of the nut 15 is in contact with the top of the upper positioning plate 11. The fixing component includes a collar 2. A set of jacks are respectively and uniformly opened on the opposite sides of the two collars 2. Iron blocks 23 are embedded in the jacks. A set of easy-pull grooves 3 are respectively opened on the left and right sides of the collar 2. Positioning posts 21 are respectively and uniformly fixedly arranged in the grooves of the lower positioning plate 1 and the upper positioning plate 11. Magnets 22 are embedded on the outer sides of the positioning posts 21. The collar 2 is inserted into the groove, the positioning post 21 is inserted into the jack, and the magnet 22 and the iron block 23 are adsorbed to each other.

[0022] Working principle: Place the turbocharger housing on the collar 2 at the top of the lower positioning plate 1, and insert the lower end face of the turbocharger housing into the collar 2 at the top of the lower positioning plate 1. At this time, rotating the nut 15 can drive the upper positioning plate 11 to move downward, thereby driving the collar 2 at the bottom of the upper positioning plate 11 to move downward, and sleeving and clamping the upper end face of the turbocharger housing. As the upper positioning plate 11 moves downward, it will squeeze the spring 14 to make it contract. When the processing of the turbocharger housing is completed, loosen the nut 15. At this time, using the elasticity of the spring 14, the spring 14 will elongate and reset, thereby driving the upper positioning plate 11 to move upward and reset. In this way, the upper positioning plate 11 and the collar 2 at the bottom of the upper positioning plate 11 can be driven to separate from the turbocharger housing, and thus the turbocharger housing can be quickly removed. The positioning column 21 is fixed in the jack of the collar 2 by the magnetic attraction of the magnet 22 to the iron block 23, so as to fix the collar 2 in the grooves of the lower positioning plate 1 and the upper positioning plate 11. Therefore, the collar 2 can be conveniently pulled out and replaced through the easy-pull groove 3. Through the quick disassembly and assembly of the collar 2, the use convenience of the device can be improved, and at the same time, the clamping adaptability of the device to turbocharger housings of different sizes can also be improved.
