[0047] In a further embodiment of the utility model, Figure 3 As shown in the figure, the second moving base 220 is provided with a first nut base 221, and the second ball screw 211 is threadedly connected with the first nut base 221.

[0048] Through cooperation of the first nut base 221 and the second ball screw 211, the structure of the second moving base 220 is simple and convenient to assemble without designing a structure cooperating with the second ball screw 211 directly on the second moving base 220.

[0049] In a further embodiment of the utility model, Figure 3 As shown in the figure, the first nut base 221 is installed on the left side of the second moving base 220, the first rotating shaft 201 of the second servo motor 240 is connected with the left end of the second ball screw 211 and located on the left side of the first nut base 221.

[0051] By arranging the support seat 212, the second ball screw 211 can be supported by the support seat 212, and the coaxiality of the first rotating shaft 201 and the second ball screw 211 is ensured.

[0052] In further embodiments of the present application, as shown in Figure 1 、 3 The left side of the second moving seat 220 is provided with a notch 222, the first nut seat 221 is arranged on the left side wall of the notch 222, the distance between the two side walls of the notch 222 in the front-rear direction is greater than the distance between the two side walls of the support seat 212 in the front-rear direction, and when the second moving seat 220 moves to the left, the support seat 212 is located in the notch 222.

[0053] By arranging the notch 222, when the second moving seat 220 moves to the left (after the drilling is completed, the original position is restored), the support seat 212 can be located in the notch 222, and then the second moving seat 220 can move to the leftmost position.

[0054] Specifically, since the second moving seat 220 is provided with the notch 222, the side wall on the left side of the second moving seat 220 includes two first side walls 225 aligned in the front-rear direction and a second side wall 226 located between the two first side walls 225, the second side wall 226 is located to the right of the first side wall 225, and the first nut seat 221 is mounted on the second side wall 226.

[0055] If the second moving seat 220 is not provided with the notch 222, the second moving seat 220 can only move to the position where the first side wall 225 and the right side wall of the support seat 212 are aligned in the front-rear direction (only to position α), and if the second moving seat 220 is provided with the notch 222, the second moving seat 220 can move to the position where the left side wall of the first nut seat 221 abuts against the right side wall of the support seat 212.

[0056] In some embodiments of the present application, the drilling assembly 200 further comprises a third moving seat 250.

[0057] The second moving seat 220 is provided with a third ball screw 223 extending in the up-down direction and a third servo motor 224 for driving the third ball screw 223 to rotate.

[0058] The third moving seat 250 is movably mounted on the second moving seat 220 and threadedly connected with the third ball screw 223, and the gang drill 230 is mounted on the third moving seat 250.

[0059] The third movable base 250 is mounted on the second movable base 220 in a manner that cooperates with the third ball screw 223 and the third servo motor 224, allowing the drilling machine 230 to stop at any position in the vertical direction, thus further improving the applicability of the drilling machine drive device.

[0060] In a further embodiment of this utility model, such as Figure 4 As shown, the second rotating shaft 2241 of the third servo motor 224 is fixedly connected to one end of the third ball screw 223, or, as... Figure 2 As shown, the third servo motor 224 is mounted on the left side of the second movable seat 220, and the third ball screw 223 and the third movable seat 250 are both mounted on the right side of the second movable seat 220. The second rotating shaft 2241 of the third servo motor 224 is connected to one end of the third ball screw 223 through a transmission structure 600.

[0061] like Figure 4 As shown, this allows the third servo motor 224 to directly drive the third ball screw 223 to rotate, as... Figure 2 As shown, the third ball screw 223 can also be driven to rotate by the transmission structure 600, and the third servo motor 224 and the third moving seat 250 are respectively located on the left and right sides of the second moving seat 220, so as to avoid the third moving seat 250 and the structure for driving the third moving seat 250 being located on the same side of the second moving seat 220, and to make full use of the positions on the left and right sides of the second moving seat 220.

[0062] Specifically, the transmission structure 600 can be driven by a belt or by other transmission methods.

[0063] In a further embodiment of the present invention, the upper end surface 101 of the base 100 is parallel or perpendicular to the horizontal plane.

[0064] like Figure 1 , 4 As shown, when the upper end face 101 of the base 100 is parallel to the horizontal plane, the drilling drive device can be used as a front horizontal drilling machine or a rear horizontal drilling machine to drill holes in the side wall of the plate. For example, when the plate is set horizontally, holes can be drilled in the front-back direction or the left-right direction of the plate.

[0065] like Figure 5 As shown, when the upper end face 101 of the base 100 is perpendicular to the horizontal plane, the drilling drive device can be used as a lower or upper drilling machine to drill holes in the end face of the plate. For example, when the plate is set horizontally, holes can be drilled in the vertical end face of the plate.

[0066] In some embodiments of this utility model, such as Figure 5As shown, the first ball screw 110 can pass through the first movable seat 210 in the front-back direction and be threaded to it. With this arrangement, the first ball screw 110 is located inside the first movable seat 210, which allows the size of the drilling drive device in the vertical direction to be designed to be smaller.

[0067] Or, such as Figure 2 As shown, the bottom of the first movable seat 210 has a groove 213, as... Figure 1 As shown, a second nut seat 214 is installed on the front or rear side of the first movable seat 210. The first ball screw 110 passes through the second nut seat 214 and is threadedly connected to it. The first ball screw 110 is located below the first movable seat 210 and at least a portion of the first ball screw 110 is located in the groove 213. With the above design, the first ball screw 110 can be designed separately from the first movable seat 210. Since at least a portion of the first ball screw 110 is located in the groove 213, the space occupied by the first ball screw 110 in the vertical direction can be reduced, so that the size of the drilling drive device in the vertical direction can be designed to be smaller.

[0068] This utility model provides three embodiments of the drilling drive device. Due to the differences in the second movable seat 220 in the three embodiments, the arrangement of the third movable seat 250 and / or the drilling rig 230 also differs. For example, as... Figure 1 , 2 As shown, in the first embodiment, the second movable base 220 of the drilling drive device is L-shaped, and a third movable base 250 and a drilling rig 230 can be installed thereon. The third movable base 250 and the drilling rig 230 can only be located on the right side of the second movable base 220; as shown Figure 4 As shown, in the second embodiment, the second movable base 220 of the drilling drive device is T-shaped, and a third movable base 250 and a drilling rig 230 can be installed thereon. The third movable base 250 and the drilling rig 230 can only be located on the left or right side of the second movable base 220; as shown Figure 5 As shown, the second movable seat 220 of the drilling drive device in the third embodiment is of type "I", and can only be equipped with a drilling 230, and the drilling 230 can only be located on the left or right side of the second movable seat 220.
