[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, an embodiment of the present application provides a CNC milling machine processing fixture, including a base 1, on which an L-shaped profiling fixing block 2 and a profiling clamping block 3 are arranged, the L-shaped profiling fixing block 2 is fixedly connected to the base 1, the profiling clamping block 3 is slidably matched with the base 1, the profiling clamping block 3 is used to clamp with the L-shaped profiling fixing block 2, and the base 1 is also provided with a driving component 4 for driving the profiling clamping block 3 to clamp the product between the L-shaped profiling fixing block 2 and the profiling clamping block 3.

[0022] like Figure 2 As shown, the contoured clamping block 3 includes a pushing portion 31 and a contoured portion 32. The bottom of the pushing portion 31 and the bottom of the contoured portion 32 form a first notch 33. The upper end of the contoured portion 32 is provided with a groove 321 for accommodating the upper protrusion of the product.

[0023] like Figure 3 As shown, the bottom of the L-shaped profiling fixing block 2 is provided with a No. 2 notch 21 for accommodating the protrusion at the lower end of the product, and one side of the L-shaped profiling fixing block 2 is provided with a No. 3 notch 22 for accommodating the protrusion at the side end of the product.

[0024] Specifically, the base 1 is square. The pushing portion 31 of the first profiling clamping block 3 is block-shaped, and the profiling portion 32 includes a first contact surface 322, a second contact surface 323 and a third contact surface 324, which respectively correspond to three different parts of the L-shaped non-standard plastic part 5. The profiling portion 32 is also provided with a groove 321 connected with the first contact surface 322, the second contact surface 323 and the third contact surface 324, and a first notch 33 is formed between the profiling portion 32 and the pushing portion 31, and the first notch 33 and the groove 321 can respectively accommodate the protrusion of one side of the L-shaped non-standard plastic part 5. The L-shaped profiling fixing block 2 is fixedly installed on a corner of the base 1 by bolts. The L-shaped profiling fixing block 2 is provided with a second notch 21 and a third notch 22 on the inner side close to the profiling clamping block 3. The second notch 21 corresponds to the convex part at the bottom of the other side of the L-shaped non-standard plastic part 5, and the third notch 22 corresponds to the convex part at the side end of the other side of the L-shaped non-standard plastic part 5. When the profiling clamping block 3 and the L-shaped profiling fixing block 2 are clamped, the top of the L-shaped non-standard plastic part 5 abuts against the upper end of the L-shaped profiling fixing block 2. The driving assembly 4 drives the pushing part 31 to move toward the L-shaped profiling fixing block 2, so that the L-shaped product is firmly clamped between the L-shaped profiling fixing block 2 and the profiling part 32.

[0025] In the above structure, the various parts of the L-shaped non-standard plastic part 5 are fixed and clamped by using the profiling clamping block 3 with the first notch 33 and the groove 321 and the L-shaped profiling fixing block 2 with the second notch 21 and the third notch 22. This arrangement is not only convenient for clamping and fixing the L-shaped non-standard plastic part 5, but also can avoid the phenomenon of position offset and deformation when processing the L-shaped non-standard plastic part 5, thereby improving the accuracy of processing.

[0026] like Figure 1 As shown, in one embodiment, the driving component 4 of the CNC milling machine processing fixture is a quick clamp, which is fixedly mounted on the base 1 and located on one side of the contoured clamping block 3, and the driving end of the quick clamp is used to drive the pushing part 31 to move along the base 1 toward the L-shaped contoured fixing block 2.

[0027] Specifically, the base 1 is provided with a positioning block on one side of the profiling clamping block, the positioning block is fixedly connected to the base 1 by bolts, and the quick clamp is fixedly installed on the side end of the positioning block, so that the driving end of the quick clamp is located on one side of the pushing portion 31 of the profiling clamping block 3, and the quick clamp is turned, and the driving end of the quick clamp contacts the pushing portion 31 and drives the pushing portion 31 and the profiling portion 32 to move toward the L-shaped profiling fixing block 2, so that the L-shaped non-standard plastic part 5 is clamped between the profiling portion 32 and the L-shaped profiling fixing block 2. Another quick clamp can also be provided at the upper end of the positioning block, which can press the top of the pushing portion 31, and when the profiling clamping block 3 is clamped with the L-shaped profiling fixing block 2, the profiling clamping block 3 can be pressed against the base 1.

[0028] This arrangement facilitates the rapid driving of the profiling clamping block 3 to clamp the L-shaped non-standard plastic part 5 on the L-shaped profiling fixing block 2, thereby facilitating the CNC milling machine to process the L-shaped non-standard plastic part 5.

[0029] like Figure 1 As shown, in one of the embodiments, a sliding groove 11 is provided on the base 1 of the CNC milling machine processing fixture, and the pushing portion 31 of the contoured clamping block 3 is slidably matched with the sliding groove 11 .

[0030] Specifically, the base 1 is provided with a strip sliding groove 11 which is inclined and extends toward the rotation angle of the L-shaped profiling fixing block 2. The bottom of the pushing portion 31 of the profiling clamping block 3 is adapted to the sliding groove 11 of the base 1. When the driving end of the quick clamp pushes the pushing portion 31, the bottom of the pushing portion 31 moves along the sliding groove 11 of the base 1 toward the L-shaped profiling fixing block 2.

[0031] This arrangement facilitates the quick clamp to push the contour clamping block 3 to move toward the L-shaped contour fixing block 2 .

[0032] like Figure 1 As shown, in one of the embodiments, the height of the profiling clamping block 3 of the CNC milling machine processing fixture is higher than the L-shaped profiling fixing block 2.

[0033] Specifically, the L-shaped non-standard plastic part 5 is first placed on the side of the L-shaped profiling fixing block 2 close to the profiling clamping block 3, the protrusions on one side of the L-shaped non-standard plastic part 5 are both located in the second notch 21 and the third notch 22 of the L-shaped square fixing block, and the top of the L-shaped non-standard plastic part 5 is against the top of the L-shaped profiling fixing block 2. When the profiling clamping block 3 clamps the L-shaped non-standard plastic part 5, the protrusion on the top of one side of the L-shaped non-standard plastic part 5 is located in the groove 321 of the profiling part 32.

[0034] The height of the contoured clamping block 3 is higher than that of the L-shaped contoured fixing block 2 so as to accommodate the protrusion at the top end of the L-shaped non-standard plastic part 5 .

[0035] like Figure 2 As shown, in one of the embodiments, the profiling portion 32 of the CNC milling machine processing fixture is provided with a certain curvature, and the profiling portion 32 is not easy to cause damage to the product when pressing the product.

[0036] Specifically, an arc is provided at the intersection of the first contact surface 322 and the second contact surface 323 of the profiling portion 32, and an arc is provided at the intersection of the second contact surface 323 and the third contact surface 324 of the profiling portion 32. When the profiling portion 32 and the L-shaped profiling fixing block 2 clamp the L-shaped non-standard plastic part 5, damage to the product can be avoided.

[0037] This arrangement can avoid damage to the L-shaped non-standard plastic part 5 during processing.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
