[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] Example

[0021] Casting precision machined C-type locking fixture, including:

[0022] A base 1, and a support mechanism 3 arranged at the upper end of the base 1, wherein a clamping and positioning mechanism 5 is clamped at the upper end of the support mechanism 3;

[0023] The clamping and positioning mechanism 5 comprises a C-shaped clamping frame 51, and a clamping adjustment bolt 52 is screwed inside one end of the C-shaped clamping frame 51;

[0024] By setting the clamping frame as a C-shaped structure to form a C-shaped clamping frame 51, the casting 6 can be conveniently clamped when it is clamped and fixed, avoiding damage to the casting 6 caused by shaking during fine processing, and a clamping adjustment bolt 52 is spirally installed at one end, so that it can be adjusted according to the thickness of the casting 6 after clamping, so that the casting 6 can be more stable after clamping. At the same time, a protective pad can be set inside the C-shaped clamping frame 51 to prevent damage to the casting 6 during the clamping process.

[0025] In order to ensure that the casting 6 can be clamped more stably, the casting 6 is placed on one side of the supporting mechanism 3. At the same time, the upper end of the casting 6 is clamped to the surface of one side of the supporting mechanism 3 through a C-shaped clamping frame 51, and is adjusted and fixed by a clamping adjustment bolt 52. It can be freely adjusted during the clamping process to enable clamping and fixing of different widths according to the size of the casting 6, and it can also avoid affecting the tool path of the boring machine spindle during the finishing process.

[0026] The support mechanism 3 includes a support frame 31, a triangular reinforcement member 32 is installed on one side of the support frame 31, and a plurality of groups of uniformly arranged rubber pads 33 are installed on the other side of the support frame 31;

[0027] The support frame 31 is provided to support the casting 6 stably, avoiding damage caused by tipping over of the casting 6 during processing. Meanwhile, a triangular reinforcement 32 is provided on one side surface to further improve the stability of the support frame 31, ensuring stability during processing and avoiding damage to the casting 6 caused by shaking. A rubber pad 33 is provided on the other side surface to protect the casting 6 when it is clamped and fixed, avoiding wear of the casting 6 due to rigid contact after clamping and fixing. Meanwhile, it can also ensure shock absorption during processing due to the tool movement of the bed spindle, avoiding wear of the casting 6.

[0028] In order to further stabilize the casting 6 after being clamped and fixed, a support pad 2 is further provided at the upper end of the base 1, and a pressing and limiting mechanism 4 is further provided at the position of the upper end of the base 1 corresponding to the supporting mechanism 3;

[0029] By arranging a support pad 2 at the upper end, the casting 6 can be supported and protected after being placed, thereby avoiding friction damage between the casting 6 and the base 1 caused by shaking during processing, and improving the stability of the casting 6 after being fixed. At the same time, a pressure limiting mechanism 4 is also arranged at a position corresponding to the support mechanism 3 at the upper end of the base 1, so that after the upper end of the casting 6 is fixed, the lower end can also be pressed and fixed to ensure the overall clamping stability.

[0030] As an improvement of the above technical solution, the pressure limiting mechanism 4 includes a fixing seat 41, and a pressure adjusting bolt 42 is screwed inside the fixing seat 41;

[0031] The fixing seat 41 is provided to limit the whole, and the pressure adjusting bolt 42 is screwed inside to adjust the size of the casting 6 during the pressure process, so as to stably clamp the castings 6 of different sizes.

[0032] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
