Detailed Implementation

[0016] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0017] A jig for holding an inserter, such as Figures 1-3 As shown, the device includes a base 1 and a limiting platform 2. The top of the base 1 is provided with several sliding grooves 5 arranged in an array. The limiting platform 2 is fixedly connected to one side of the base 1. The side of the limiting platform 2 that is in contact with the base 1 is provided with a limiting groove 3 with a triangular cross-section. Clamping blocks 4 for clamping inserts are slidably connected in each of the sliding grooves 5. One end of the sliding groove 5 extends towards the limiting platform 2 and is open. The end of the clamping block 4 facing the limiting platform 2 is provided with a V-shaped clamping part that cooperates with the limiting groove 3 and contacts the outer peripheral wall of the insert. By moving the clamping block 4, the outer peripheral wall of the insert is clamped, thereby fixing the insert. The included angle of the V-shaped clamping part and the included angle of the triangle of the limiting groove 3 are both 60°, so that the V-shaped clamping part and the triangular limiting groove 3 form a double conical self-centering surface, making the positioning of the insert more stable. A mounting platform 6 is fixedly connected to the side of the base 1 away from the limiting platform 2. A stud 7 is threaded onto the mounting platform 6. One end of the stud 7 extends into the sliding groove 5 and is relatively fixed to the clamping block 4. By rotating the stud 7, the clamping block 4 is controlled to move within the sliding groove 5. A recessed hole 11 is provided at the end of the clamping block 4 away from the limiting platform 2. A limiting member 8 is fixedly connected to the end of the stud 7. The limiting member 8 includes a connecting part 9 and is fixedly connected to the end of the stud 7 through the connecting part 9, so that the limiting member 8 forms a stepped shaft. The limiting member 8 extends into the recessed hole 11. The diameter of the limiting member 8 is larger than the diameter of the connecting part 9 but smaller than the diameter of the stud 7. The diameter of the concave hole 11 is smaller than the diameter of the stud 7. A limiting post 10 is threadedly connected to the bottom of the clamping block 4. The limiting post 10 extends between the limiting member 8 and the stud 7 and contacts the outer peripheral wall of the connecting member. The end is provided with a guide surface that matches the end face of the limiting member 8. A chamfer is provided between the limiting member 8 and the connecting part 9 and fits against the guide surface. When the stud 7 is tightened, the end face of the stud 7 fits against the side of the clamping block 4, pushing the clamping block 4 toward the limiting platform 2. When the stud 7 is loosened, the limiting member 8 and the limiting post 10 abut against each other, thereby driving the clamping block 4 away from the limiting platform 2, achieving the effect of reciprocating movement of the clamping block 4, thereby clamping the insert. A clamping plate 12 is detachably connected to the top of the limiting platform 2 on the side away from the limiting platform 2 by bolts. The clamping block 4 has an L-shaped cross section, so that the top of the clamping block 4 extends out of the sliding groove 5. The clamping plate 12 can clamp the top of the clamping block 4 to prevent the clamping block 4 from tilting when it moves through the stud 7, which would affect the clamping effect. The clamping plate 12 is detachably installed on the top of the limiting platform 2 by bolts. Its lower surface is clearance-fitted with the upper surface of the clamping block 4. A clamping bolt 13 is threaded on the clamping plate 12 and released from the top of the clamping block 4. The clamping bolt 13 can further prevent the clamping block 4 from tilting when it moves through the stud 7, ensuring the stability of the movement of the clamping block 4.

[0018] Working principle: The side of the limiting platform 2 with the limiting groove 3 facing the base 1 is fixed to the side of the base 1 with bolts. The stud 7 is threaded onto the mounting platform 6 and passes through it. The concave hole 11 of the clamping block 4 is aligned with the end of the stud 7 with the limiting member 8, so that the limiting member 8 extends into the concave hole 11. Using an Allen wrench, the limiting post 10 is screwed into the concave hole 11 until it contacts the connecting part 9, thus completing the installation of the clamping block 4 and the mounting platform 6. The clamping block 4 is aligned with the slide groove 5, and the top of the clamping block 4 extends above the slide groove 5, so that the mounting platform 6 is located on the side of the base 1 away from the limiting platform 2 and is fixed with bolts, thus completing the installation of the mounting platform 6 and the base 1. The pressure plate 12 is detachably connected to the top of the limiting platform 2 on the side away from the limiting platform 2 with bolts, and the pressure bolt 13 is tightened so that the pressure bolt 13 contacts the top of the clamping block 4, thus completing the installation of the entire fixture. When the insert is placed between the limiting groove 3 and the clamping block 4, and the stud 7 is tightened, the end face of the stud 7 is in contact with the side of the clamping block 4, pushing the clamping block 4 toward the limiting platform 2 until the insert is in contact with the V-shaped clamping part and the inner wall of the limiting groove 3, thus completing the clamping of the insert. This makes the clamping of the insert more stable and has a self-centering effect, ensuring the positioning effect of the insert.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
