[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1-2 , a casing side opening positioning device, comprising:

[0021] A positioning mandrel 1 is provided at its first end with a mandrel 11, and a sleeve 2 can be sleeved on the mandrel 11; a positioning mechanism for positioning the sleeve 2 is also provided on the positioning mandrel 1; positioning is achieved by sleeved the sleeve 2 on the mandrel 11, and the positioning mandrel 1 is installed on the chuck of a machine tool to avoid the chuck directly clamping the sleeve 2, thereby preventing the sleeve 2 from being squeezed and deformed, and ensuring stable and reliable processing.

[0022] The clamping mechanism can be connected to the mandrel 11 and clamp the sleeve 2; the sleeve 2 is clamped on the positioning mandrel 1 by the clamping mechanism. The clamping part 13 is arranged on the second end of the positioning mandrel 1, and the clamping part 13 can be connected to the machine tool. The clamping part 13 is installed on the chuck of the machine tool to prevent the chuck from directly clamping the sleeve 2, preventing the sleeve 2 from being squeezed and deformed, and the processing is stable and reliable.

[0023] The clamping mechanism is a pressing plate 3, which can be connected to the positioning mandrel 1 through a bolt 4. The pressing plate 3 is fixed by the bolt 4, and the sleeve 2 is squeezed by the pressing plate 3, so as to fix the sleeve 2.

[0024] The positioning mechanism is a step 12, and the step 12 can position the first end of the sleeve 2. The step 12 can block the first end of the sleeve 2 and play a positioning role.

[0025] The length of the mandrel 11 is smaller than the length of the sleeve 2 , so that the pressing plate 3 can be reliably pressed onto the sleeve 2 .

[0026] A guide groove 111 corresponding to the processing hole on the sleeve 2 is provided on the positioning core rod 1. When the sleeve 2 is processed to open a hole, the guide groove 111 plays a role in avoiding the tool.

[0027] The pressing plate 3 is provided with a slot 31 extending from the center of the pressing plate 3 to the outer end. The bolt 4 can slide in the slot 31, so that the pressing plate 3 can be replaced easily to meet the processing requirements of different types of sleeves 2.

[0028] After adopting the above structure, the sleeve can be reliably positioned to prevent the sleeve from being squeezed and deformed, and the processing is stable and reliable.
