[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] according to Figure 1-2 The utility model provides a quick positioning fixture for an oil pump seat processing machine tool, comprising: a base plate 1, a side plate 2, a positioning column 3, a pressing structure 4, a boss 5, and a balancing block 6.

[0019] The side plate 2 is disposed on one side of the base plate 1. The positioning column 3 is disposed on the side of the base plate 1 away from the side plate 2. The clamping structure 4 is disposed on the side of the base plate 1 closer to the side plate 2. The positioning column 3 includes a fixing platform 31 and a boss 32. The positioning column 3 is disposed relative to the base plate 1. The boss 32 is disposed on the fixing platform 31. The radius of the fixing platform 31 is larger than the radius of the boss 32. There are two bosses 5. The end faces of the bosses 5 and the end faces of the fixing platforms 31 are coplanar. There are two clamping structures 4. The clamping structures 4 are disposed relative to each other on the base plate 1. The bosses 5 are disposed on the sides of the two clamping structures 4 that are relatively close to each other. The balancing weight 6 is disposed on the side of the boss 5 away from the base plate 1. The clamping structure 4 includes a screw 41, a clamping block 42, and a nut 43. The screw 41 is disposed on the base plate 1. The clamping block 42 is mounted on the side of the screw 41 away from the base plate 1. The nut 43 is mounted on the screw 41. The nut 43 is arranged on the side of the pressing block 42 away from the base plate 1. The nut 43 corresponds to the screw rod 41. The pressing block 42 includes: a connecting block 421, a resistance block 422, and a fixed block 423. The connecting block 421 is sleeved on the screw rod 41. The connecting block 421 is movable relative to the screw rod 41. One end of the connecting block 421 is connected to the resistance block 422, and the other end is connected to the fixed block 423. The fixed block 423 is longer than the resistance block 422.

[0020] Figure 3 The oil pump seat of the present invention is named workpiece 7, which includes a base plate 71. A positioning hole 711 is opened on one side of the base plate 71. The positioning hole 711 corresponds to the boss 32. Figure 1-4When the workpiece 7 needs to be fixed, the side of the substrate 71 without the positioning holes 711 is made to face the utility model and approach it, and then the two positioning holes 711 are sleeved on the two bosses 32. Through the two positioning points, the workpiece 7 can be positioned in a suitable processing position, and the substrate 71 is placed on the fixed table 31 and the boss 5. Then, the connecting block 421 of the clamping block 42 is rotated on the screw 41, so that the interference block 422 is rotated to the side of the substrate 71 away from the bottom plate 1, and then the connecting block 421 is moved toward the bottom plate 1 so that the interference block 422 fits the substrate 71. Then, the nut 43 is rotated so that the nut 43 presses the connecting block 421 so that the interference block 422 interferes with the substrate 71, so that the substrate 71 interferes with the fixed table 31 and the boss 5. That is, the substrate 71 is fixed through the two clamping structures 4. The substrate 71 is fixed on the boss 5 and the fixed table 31. Compared with being directly fixed on the base plate 1, the contact area of ​​the base plate 1 is large, and it is more difficult to keep it flat. The uneven surface will cause the substrate 71 to tilt or become unstable when being fixed, which may easily lead to dimensional deviation or severe vibration causing damage to the workpiece. The boss 5 and the fixed table 31 make the contact area of ​​the substrate 71 smaller, making it easier to keep it flat. The boss 5 and the fixed table 31 make the edge structure of the substrate 71 suspended in the air, at a certain distance from the base plate 1. When processing the edge structure, the processing tool is not easy to contact the base plate 1, preventing the base plate 1 from being affected when processing the edge of the substrate 71.

[0021] When the workpiece 7 is positioned on the base plate 1, since the clamping structure 4 is rotatable, if the connecting block 421 rotates, it may drive the interference block 422 to rotate, so that the interference block 422 reaches the fixed position of the base plate 71 away from the base plate 1. When the base plate 71 is positioned by the positioning column 3, the base plate 71 will pass the position where the interference block 422 is located, that is, it will conflict with the interference block 422. The utility model is provided with a fixed block 423. When fixing the workpiece 7, the connecting block 421 can be rotated to drive the fixed block 423 to rotate, so that the fixed block 423 is close to the boss 5 and conflicts with it. At this time, neither the interference block 422 nor the fixed block 423 is in the position where the workpiece 7 needs to pass when positioning. That is, through this operation, the clamping structure 4 can be quickly moved to the appropriate position to prevent the positioning of the workpiece 7 from being affected, thereby facilitating the rapid positioning of the workpiece 7. In addition, the fixed block 423 can also make the clamping structure 4 more stable. The fixing block 423 is longer than the interference block 422, so that when the workpiece 7 is fixed by the clamping structure 4 and the interference block 422 is in conflict with the base plate 71, the fixing block 423 can just conflict with the bottom plate 1, and then the connecting block 421 is compressed by the nut 43. Compared with the structure without the fixing block 423, such a structure has more support points, and the combined forces at both ends of the clamping structure 4 are in the same straight line, which makes the clamping structure 4 more stable. The present invention needs to be installed on a machine tool when in use. The machine tool can rotate the present invention around the center of the side plate 2 to facilitate processing of multiple positions of the workpiece 7. However, after the present invention fixes the workpiece 7, its center of gravity is close to the side of the side plate 2 close to the bottom plate 1, that is, it is unbalanced. The present invention is provided with a balancing block 6 on the side of the side plate 2 away from the boss 5, so that after the workpiece 7 is fixed, the center of gravity of the present invention and the workpiece as a whole is on the central axis of the rotating shaft, so as to ensure that the whole is relatively balanced during processing and avoid vibration, noise and other situations that affect the processing process. When the workpiece 7 is fixed on the base plate 1 , there is a certain distance between the workpiece 7 and the balancing block 6 , that is, the balancing block 6 will not affect the fixation of the workpiece.

[0022] The working principle and use process of this utility model:

[0023] When workpiece 7 needs to be fixed, the connecting block 421 is rotated to drive the interference block 422 and the fixing block 423 to rotate so that the interference block 422 interferes with the boss 5, and then the workpiece 7 is moved closer to the utility model, and the side of the base plate 71 without the positioning hole 711 faces the side plate 2, so that the positioning hole 711 is sleeved on the protrusion 32, and the base plate 71 is placed on the fixing table 31 and the boss 5, and then the connecting block 421 is rotated to drive the interference block 422 and the fixing block 423 to rotate, and the interference block 422 is rotated until the base plate 71 is away from the bottom plate 1 side, and then the connecting block 421 is moved closer to the bottom plate 1, so that the interference block 422 contacts the base plate 71, and the fixing block 423 contacts the bottom plate 1, and then the nut 43 is rotated so that the nut 43 presses the connecting block 421, so that the interference block 422 and the fixing block 423 interfere with the base plate 71 and the bottom plate 1 respectively, so that the base plate 71 of the workpiece 7 is fixed on the bottom plate 1, and then processing can be carried out.

[0024] To sum up, the present invention sets a positioning column and a clamping structure, so that the workpiece can be initially positioned on the base plate by the positioning column and then fixed by the clamping structure. It can be suitable for such irregular workpieces, so that the workpiece can be fixed more stably on the present invention, which is conducive to the processing process.
