[0002] In the automobile manufacturing industry, the injector body is an important component in the diesel engine high-pressure common rail system. In the process of processing the high-pressure oil hole of the injector body, multi-axis gun drilling is currently recognized as a fast and reliable processing method. During multi-axis gun drilling, the clamping length of the gun drill tool of each axis must be kept consistent. Only in this way can the size of the high-pressure oil hole of the injector body processed by each axis be guaranteed to be consistent. Therefore, keeping the clamping length of the gun drill tool of each axis consistent is an important means to ensure the accuracy of gun drilling. The pre-adjustment of the gun drill tool change is particularly important.
[0003] However, most of the current methods for changing the tool for the injector body gun drill are traditional methods. This traditional method is to use manual hand-held, adjust the positioning screws with a wrench, and adjust the approximate position of the gun drill tool. It is time-consuming and laborious to adjust the screws by hand-held, and the tool length cannot be accurately adjusted. It is easy to damage the gun drill due to unstable hand-held, and it cannot adapt to the industrial development trend represented by automation and precision. Utility Model Content

DETAILED DESCRIPTION
[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is further described in detail in conjunction with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0020] like Figure 1-Figure 3As shown, the embodiment of the utility model provides a fixture for pre-adjusting the tool change of the high-pressure oil hole gun drill of the injector body, including a base 1, a first station module 2 and a second station module 3 are arranged above the base 1, and a measuring device 4 is also arranged above the base 1. The first station module 2 is used to install the adjustment screw 16 of the tool 15; the measuring device 4 is a length measuring device, and the second station module 3 and the measuring device 4 cooperate to adjust the length of the tool 15 by measuring the length of the mandrel. The mandrel is a standard component, that is, the length of the tool required to process the high-pressure oil hole of the injector body. By adopting this tool change pre-adjustment method, the tool change efficiency can be greatly improved compared with the traditional method, and the time can be shortened. When processing the high-pressure oil hole of the injector body, the scrap rate and production cost can be greatly reduced, and the production efficiency can be improved. A tool placement area 14 is arranged on the base 1. The tool placement area 14 is convenient for storing tools, making it more convenient and quick to prepare the tool 15.

The first positioning block 5 is preferably a V-shaped positioning block, which can adapt to tools 15 of different sizes, so that it can be compatible with several types of tools 15. In order to better fix the tool 15, a flat buckle 7 is provided at one side opening of the first positioning block 5. This prevents the tool 15 from shaking when installing the adjustment screw 16, facilitates installation, and improves work efficiency.
[0022] The second station module 3 includes a second positioning block 8, which is fixed to the base 1 by screws, and the second quick caliper 9 is fixed to the top of the second positioning block 8 by screws; the second positioning block 8 is preferably a V-shaped positioning block, which can adapt to tools 15 of different sizes, so that it can be compatible with several types of tools 15. .
