[0042] Example 1

[0043] like Figures 1 to 5 As shown, the quick clamping fixture for cutting blade tail end processing of this embodiment includes a base 10, a slider assembly 20 and an adjusting bolt 30, wherein:

[0044] A slider installation slot 11 is provided on the top of the base 10;

[0045] The slider assembly 20 is movably disposed in the slider installation slot 11, and includes a plurality of first sliders 21 and a second slider 22 arranged in sequence along a first straight line direction;

[0046] Both ends of all first sliders 21, one end of the second slider 22 facing the first slider 21, and the front side wall of the slider mounting groove 11 facing the first slider 21 are provided with outwardly facing profiling grooves 23, a single profiling groove 23 corresponds to the shape of half of the cutting blade 1, and two profiling grooves 23 with opposite notches correspond to one cutting blade 1;

[0047] The first slider 21 at the front end of the slider assembly 20 and the front side wall of the slider installation groove 11, the two adjacent first sliders 21, and the second slider 22 at the rear end of the slider assembly 20 and the adjacent first sliders 21 are all movably connected through a plurality of linear springs 24;

[0048] like Figure 1 , 6As shown, the adjusting bolt 30 is installed on the base 10 through a threaded hole 18 that passes through the rear side wall of the slider installation slot 11 along the first straight line direction, and the rear end of the adjusting bolt 30 abuts against the rear end of the second slider 22.

[0049] In this embodiment, the base 10 is in a rectangular block shape, and the first straight line direction is consistent with the length direction of the base 10. The first sliders 21 and the second sliders 22 are also square blocks, and the number of the first sliders 21 is seven.

[0050] Further, such as Figure 7 , 8 As shown, both ends of the first slider 21 and the second slider 22 are provided with limiting recesses 25 at their bottoms near the first slider 21, and a plurality of slider limiting posts 12 corresponding to the limiting recesses 25 are provided at the bottom of the slider installation slot 11. Figure 4 , 6 As shown, in this embodiment, a slider limit pile 12 is shared between two adjacent first sliders 21 and between the second slider 22 and the adjacent first slider 21. The slider limit pile 12 can abut against the inner wall of the limit recess 25 to limit the movement position of the first slider 21 and the second slider 22, and does not affect the clamping between adjacent sliders. In this embodiment, in the first straight line direction, the widths of the slider limit piles 12 are different. In actual application, a suitable width can be set according to the performance of the spring used, so that when the linear spring 24 pushes the slider to release the workpiece, it can ensure that there is enough clearance between any two adjacent sliders or between the front side wall of the slider installation groove and the adjacent slider to easily remove the processed workpiece.

[0051] Further, such as Figure 2 , 3 As shown, limiting steps 13 are provided on both sides of the bottom of the slider installation groove 11, and flanges 26 extending in the direction of the limiting steps 13 are provided at the bottom of both side edges of the first slider 21 and the second slider 22, and the height of the flanges 26 is consistent with the height of the limiting steps 13. A plurality of pressure strips 14 are filled between the sides of the first and second sliders 21 and 22 and the side walls of the slider installation groove 11, and the pressure strips 14 are located above the limiting steps 13 and the flanges 26, and are connected to the base 10 by a plurality of fastening bolts 15. The side of the pressure strip 14 can abut against the side of the first and second sliders 21 and 22, and the bottom of the pressure strip 14 can abut against the top of the flange 26, so as to limit the slider assembly 20, prevent the slider assembly 20 from shaking in the slider installation groove 11 or falling out of the slider installation groove 11, so that the first and second sliders 21 and 22 can only move along the first straight line direction under the action of external force. In this embodiment, there are four pressure strips 14 , which are arranged opposite to each other in pairs, and each pressure strip 14 is connected to the base 10 via two fastening bolts 15 .

[0052] Further, such as Figure 5As shown, the slider assembly 20 further includes a plurality of guide posts 27 arranged along the first straight line direction, and guide post mounting holes 28 are provided at both ends of all first sliders 21, at one end of the second slider 22 facing the first slider 21, and on the front side wall of the slider mounting groove 11 facing the first slider 21. The two ends of the guide posts 27 are respectively passed through the guide post mounting holes 28 to penetrate between two adjacent first sliders 21, between the second slider 22 and the adjacent first slider 21, and between the first slider 21 at the front end of the slider assembly 20 and the front side wall of the slider mounting groove 11. The guide posts 27 can improve the stability of the first and second sliders 21 and 22 during movement, reduce shaking, and help improve processing accuracy.

[0053] Furthermore, the linear springs 24 are correspondingly sleeved on the guide columns 27 one by one, and the two ends of the linear springs 24 are respectively abutted against the two adjacent first sliders 21, or respectively abutted against the second slider 22 and its adjacent first slider 21, or respectively abutted against the first slider 21 located at the front end of the slider assembly 20 and the front side wall of the slider mounting groove 11.

[0054] Furthermore, the guide column mounting hole 28 is a cylindrical countersunk hole, the small diameter channel of the cylindrical countersunk hole is adapted to the end of the guide column 27, and the end of the linear spring 24 is against the step in the cylindrical countersunk hole, which has better stability.

[0055] In this embodiment, the two guide post mounting holes 28 located at the two ends of the first sliding block 21 have different depths, which is used to prevent direction errors and reduce assembly errors.

[0056] Preferably, there are two linear springs 24 and two guide posts 27 between two adjacent first sliders 21, between the second slider 22 and the adjacent first slider 21, and between the first slider 21 at the front end of the slider assembly 20 and the front side wall of the slider mounting groove 11.

[0057] In this embodiment, in order to facilitate assembly, a plurality of square slots 172 and a plurality of circular plug holes 171 are further provided on the front side wall of the slider installation groove 11, and the slots 172 and the plug holes 171 correspond to the guide post installation holes 28 one by one. On the groove wall of the slider installation groove 11, the plug holes 171, the slots 172, and the guide post installation holes 28 are sequentially connected and connected from the outside to the inside along the first straight line direction. The plug hole 171 is coaxial with the guide post installation hole 28, and can be used for the guide post 27 to pass through, so that the guide post at the front end can be smoothly inserted into the front side wall of the slider installation groove 11 through the plug hole 171. The slot 172 opens upward, and a square plug block 173 adapted thereto is inserted in the slot 172. The plug block 173 can abut against the end of the guide post 27 inserted on the front side wall of the slider installation groove 11 at the front end after all the guide posts 27 are installed in place, thereby preventing the guide post from falling out of the slider.

[0058] Further, such as Figure 6 As shown, the base 10 is also provided with a plurality of drainage and chip removal grooves 16 with both ends connected therethrough. The drainage and chip removal grooves 16 are arranged one by one below the slider limit piles 12. The top of the drainage and chip removal grooves 16 intersects with the slider mounting groove 11 to form drainage and chip removal openings 161. The waste chips and cutting fluid generated during the machining process can flow into the drainage and chip removal grooves 16 below through the drainage and chip removal openings 161, which is convenient for cleaning and prevents waste chips from affecting the machining accuracy.

[0059] Preferably, the length direction of the drainage and chip removal groove 16 is perpendicular to the first straight line direction, and the upper width of the drainage and chip removal groove 16 is smaller than the lower width, which can ensure the connection strength between the upper slider limit pile 12 and the bottom surface of the slider installation groove 11, and facilitate the smooth discharge of waste chips below. In this embodiment, the cross section of the drainage and chip removal groove 16 is "convex" shaped.

[0060] Further, such as Figures 7 to 9 As shown, the cutting blade 1 is in an I-shaped shape as a whole, including a vertical plate portion 2 located in the middle and two horizontal plate portions 3 symmetrically arranged at both ends of the vertical plate portion 2, each horizontal plate portion 3 includes two horizontal plate halves 4 extending to both sides of the vertical plate portion 2. The profiling groove 23 includes two U-shaped clearance grooves 231, and the two clearance grooves 231 correspond to the two horizontal plate halves 4 located on the same side of the vertical plate portion 2, respectively, and a convex block structure 232 is formed between the two clearance grooves 231. In this embodiment, the bottom of the clearance groove 231 is connected with the limiting notch 25, and the size of the clearance groove 231 is slightly larger than the horizontal plate half 4. During processing, cutting fluid and metal debris can fall from the gap to the bottom, which is convenient for subsequent cleaning.

[0061] When in use, first place the end face 5 of the semi-finished cutting blade 1 facing upward into the profiling groove 23, and the bottom of the semi-finished cutting blade 1 is supported by the slider limit pile 12; then turn the adjusting bolt 30 to push the second slider 22 to move toward the first slider 21, and then drive the first sliders 21 to move one by one toward the front side wall of the slider installation groove 11, and at the same time, the linear spring 24 is compressed, the sliders gradually approach each other, and the gap between the profiling grooves 23 with opposite notches is reduced; after the adjusting bolt 30 is tightened, the vertical plate portion 2 of each semi-finished cutting blade 1 is clamped from both sides by the protrusion structures 232 in the two profiling grooves 23, thereby fixing the cutting blade 1. After the processing is completed, it is only necessary to loosen the adjusting bolt 30, and all the first sliders 21 and the second sliders 22 move toward the rear side wall of the slider installation groove 11 under the action of the spring force until the limit notch 25 at the bottom abuts against the side of the slider limit pile 12. After the cutting blade 1 is released, it falls on the limiting column of the slider. After the finished cutting blade 1 is taken out, the next batch of semi-finished products can be loaded for further processing.

[0062] The above implementation modes are preferred examples of the present invention and are not intended to limit the protection scope of the present invention.
