[0038] According to the above structural features of the present application, the embodiments of the present application are further described:

[0039] With reference to Figures 1-2 , the embodiment provides a numerical control machine tool clamping device, which comprises a base 1, a sliding block 4, an abutting block 5, a first clamping plate 6 and a second clamping plate 7; the sliding block 4 is slidingly arranged on the upper surface of the base 1, and the abutting block 5 is fixedly arranged at one end of the upper surface of the base 1. The sliding block 4 can reciprocally slide along the length direction of the base, so as to change the distance between the sliding block 4 and the abutting block 5. Then, the user places the workpiece to be processed between the sliding block 4 and the abutting block 5, so as to realize clamping of the workpiece to be processed.

[0040] With reference to Figure 1 , Figure 4 and Figure 5The slider 4 is connected to the first clamping plate 6, and the abutment block 5 is connected to the second clamping plate 7. The first clamping plate 6 is installed on the side wall of the slider 4 near the abutment block 5, and the second clamping plate 7 is installed on the side wall of the abutment block 5 near the slider 4. Thus, the first clamping plate 6 and the second clamping plate 7 can clamp the two sides of the workpiece respectively. The first clamping plate 6 has a first clamping surface 60, which is located on the side wall of the first clamping plate 6 near the second clamping plate 7; the second clamping plate 7 has a second clamping surface 70, which is located on the side wall of the second clamping plate 7 near the first clamping plate 6; the first clamping surface 60 and the second clamping surface 70 respectively contact the workpiece to achieve clamping; the surfaces of the first clamping surface 60 and the second clamping surface 70 are respectively provided with friction textures (such as mesh grooves) to increase the friction between them and the workpiece, thereby improving clamping stability. The distance between the first clamping surface 60 and the second clamping surface 70 can be adjusted. When the slider 4 moves the first clamping plate 6, the distance between the first clamping surface 60 and the second clamping surface 70 changes to clamp / release the workpiece.

[0041] Reference Figure 1 , Figure 4 and Figure 5 The slider 4 is detachably connected to the first clamping plate 6, and the abutment block 5 is detachably connected to the second clamping plate 7. Multiple replaceable first clamping plates 6 are provided, each with a different shape of first clamping surface 60 (e.g., planar, arc-shaped, inclined, V-groove, etc.). Multiple replaceable second clamping plates 7 are also provided, each with a different shape of second clamping surface 70 (e.g., planar, arc-shaped, inclined, V-groove, etc.). The first and second clamping surfaces 60 and 70 are adapted to the irregularly shaped workpiece, thereby achieving stable clamping of the workpiece. During production, the user can replace different first clamping plates 6 and second clamping plates 7 to clamp different irregularly shaped workpieces.

[0042] Reference Figure 4 and Figure 5 The first clamping plate 6 is upright, and the first horizontal plate 61 is fixedly connected to the side wall of the first clamping plate 6 (for example, by bolt or by integral connection). The slider 4 is provided with a first top groove 41 that can accommodate the first horizontal plate 61 and a first side groove 42 that can accommodate the first clamping plate 6. The first horizontal plate 61 is provided with a first insertion hole 611, and a first bolt 612 is inserted into the first insertion hole 611. The bottom end of the first bolt 612 is screwed into the first screw hole 43 at the bottom surface of the first top groove 41 by thread.

[0043] Reference Figure 4 and Figure 5, the second clamping plate 7 is vertical, the side wall of the second clamping plate 7 is fixedly connected with a second horizontal plate 71 (for example, fixedly connected through bolts or fixedly connected in an integrated manner), the abutting block 5 is provided with a second top groove 51 capable of accommodating the second horizontal plate 71 and a second side groove 52 capable of accommodating the second clamping plate 7, the second horizontal plate 71 is provided with a vertical second insertion hole 711, and a second bolt 712 is inserted into the second insertion hole 711.

[0044] In the prior art, the first clamping plate 6 and the sliding block 4 are directly connected through the transversely arranged bolt, so that a counter-sunk hole needs to be formed at the position of the first clamping surface 60, thereby causing the frictional pattern of the first clamping surface 60 to be damaged, and thus the clamping stability is reduced; similarly, the second clamping plate 7 and the abutting block 5 are directly connected through the transversely arranged bolt, so that a counter-sunk hole needs to be formed at the position of the second clamping surface 70, thereby causing the frictional pattern of the second clamping surface 70 to be damaged, and thus the clamping stability is reduced. Figure 4 In order to avoid such problems, the first bolt 612 and the second bolt 712 are vertically arranged, and the first clamping plate 6 and the sliding block 4 are indirectly connected through the first horizontal plate 61 and the first bolt 612, and the second clamping plate 7 and the abutting block 5 are indirectly connected through the second horizontal plate 71 and the second bolt 712. Figure 5 Therefore, it is not necessary to form a counter-sunk hole on the frictional pattern, the integrity of the frictional pattern is ensured, and the clamping stability is improved.

[0045] At the moment when the first clamping plate 6 is loosened from the workpiece, the slight elastic deformation of the first clamping plate 6 rebounds, so that the bottom end of the first clamping plate 6 slightly rotates outward, and over time, the gap between the bottom end of the first clamping plate 6 and the first side groove 42 becomes larger and larger; similarly, the slight elastic deformation of the second clamping plate 7 rebounds, so that the bottom end of the second clamping plate 7 slightly rotates outward, and the gap between the second clamping plate 7 and the second side groove 52 also becomes larger and larger; and the connection position of the first horizontal plate 61 and the first clamping plate 6 repeatedly bends, so that plastic deformation is formed, and thus the bottom end of the first clamping plate 6 is raised and cannot be reset; similarly, the connection position of the second horizontal plate 71 and the second clamping plate 7 repeatedly bends, so that plastic deformation is formed, and thus the bottom end of the second clamping plate 7 is raised and cannot be reset. Figure 4 When the bottom end of the first clamping plate 6 and the bottom end of the second clamping plate 7 are raised, metal particles / scrap produced during the machining process will enter the gap between the first clamping plate 6 and the first side groove 42 and the gap between the second clamping plate 7 and the second side groove 52, and then the metal particles / scrap act as a supporting force, so that the first clamping surface 60 and the second clamping surface 70 cannot be parallel even in the state of clamping the workpiece, and thus stable clamping cannot be achieved. Figure 5The first clamping plate 6 has a first pulling protrusion 62 at the bottom of its side wall, and a first slot 44 at the bottom of its side wall. The first pulling protrusion 62 can be fitted into the first slot 44. The second clamping plate 7 has a second pulling protrusion 72 at the bottom of its side wall, and a second slot 54 at the bottom of its side wall. The second pulling protrusion 72 can be fitted into the second slot 54. The first pulling protrusion 62 is used to apply a downward pulling force to the bottom end of the first clamping plate 6, thereby achieving a tight fit between the bottom end of the first clamping plate 6 and the side wall of the first side groove 42 (when the bottom end of the first clamping plate 6 tends to rotate outward, the bottom surface of the first pulling protrusion 62 and the bottom surface of the first slot 44 press against each other, thereby preventing the first pulling protrusion 62 from coming out of the first slot 44), and preventing the bottom end of the first clamping plate 6 from rotating outward, which would cause stress concentration and repeated bending at the connection between the first horizontal plate 61 and the first clamping plate 6. The second pull-up protrusion 72 is used to apply a downward pull-up force to the bottom end of the second clamping plate 7, thereby achieving a tight fit between the bottom end of the second clamping plate 7 and the side wall of the second side groove 52 (when the bottom end of the second clamping plate 7 has a tendency to rotate outward, the bottom surface of the second pull-up protrusion 72 and the bottom surface of the second slot 54 press against each other, thereby preventing the second pull-up protrusion 72 from coming out of the second slot 54), and preventing the bottom end of the second clamping plate 7 from rotating outward, which would cause the second horizontal plate 71 to be repeatedly bent due to force concentration at the connection position with the second clamping plate 7.

[0046] Reference Figure 4 and Figure 5 The first horizontal plate 61 and the first connecting protrusion 62 are both located on the side wall of the first clamping plate 6 facing away from the second clamping plate 7, with the first horizontal plate 61 positioned above the first connecting protrusion 62. Similarly, the second horizontal plate 71 and the second connecting protrusion 72 are both located on the side wall of the second clamping plate 7 facing away from the first clamping plate 6, with the second horizontal plate 71 positioned above the second connecting protrusion 72. This allows for easy assembly and disassembly of the first horizontal plate 61 and the slider 4, as well as the second horizontal plate 71 and the abutment block 5, facilitating the replacement of the first clamping plate 6 and the second clamping plate 7.

[0047] Reference Figure 4 and Figure 5 The first top groove 41 and the first side groove 42 are arranged vertically in an L-shape and are interconnected. The first clamping plate 6 and the first horizontal plate 61, which are connected in an L-shape, can be fastened to the upper sharp corner of the slider 4. The second top groove 51 and the second side groove 52 are arranged vertically in an L-shape and are interconnected.
