[0002] A radial drilling machine is a type of drilling machine in which the radial arm can rotate and move up and down around the column, and the spindle box usually moves horizontally on the radial arm. When machining holes on a vertical drilling machine, the alignment of the tool and the workpiece (alignment refers to the process of making the cutting point or axis of the tool coincide with the machining position of the workpiece) is achieved by moving the workpiece.

[0003] When drilling square tube workpieces, vises are usually used to clamp the workpieces. Depending on the drilling requirements, when drilling on different planes of the square tube workpieces, the workpieces need to be removed from the vise, and the faces need to be reversed before being re-clamped. The process of removing the square tubes wastes time and affects the drilling efficiency of the square tube workpieces. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, a positioning and locking mechanism for a radial drilling machine includes a drilling machine connecting seat 1, a workpiece changing assembly 2, which flips the workpiece without disassembling it to shorten the drilling time; and a drive assembly 3, which drives the workpiece changing assembly 2 to tilt the workpiece to process inclined holes in the workpiece.

[0041] The workpiece changing assembly 2 includes: a rotary disk 21, which is connected to the drilling machine connecting seat 1 via a rotating shaft 211; a support frame 22, one end of which is connected to the rotary disk 21, and the other end of which is rotatably connected to a workpiece sleeve 221, the inlet end of which is equipped with a clamping element 222 for clamping the workpiece; and a locking element 23 for fixing the rotation angle of the workpiece sleeve 221.

[0042] Thus, the square tube workpiece is inserted into the workpiece sleeve 221, and the clamping member 222 is used to fix the square tube workpiece. When it is necessary to drill holes on different sides of the square tube workpiece, the workpiece sleeve 221 is rotated in the support frame 22, which causes the clamping member 222 and the workpiece to deflect together. Then, the locking member 23 is used to fix the position of the workpiece sleeve 221 in the support frame 22, and the radial drilling machine drills holes. When adjusting the drilling surface of the square tube workpiece, it is not necessary to disassemble and re-clamp the workpiece, saving processing time and improving the drilling efficiency of the square tube workpiece.

[0043] Specifically, the rotary disk 21 rotates in the drill press connecting seat 1 via the rotating shaft 211. The rotating shaft 211 is connected to the drill press connecting seat 1 via bearings. The support frame 22 can move with the rotary disk 21. The workpiece sleeve 221 initially stores the square tube workpiece, and the clamping component 222 fixes the workpiece.

[0044] In some embodiments, such as Figure 2 As shown, the clamping component 222 includes: an annular shell 222a, the central hole of the annular shell 222a is connected to the inlet end of the workpiece sleeve 221; and multiple threaded tubes 222b, which are evenly distributed along the outer periphery of the annular shell 222a, with push rods 222c connected to the internal threads of the threaded tubes 222b.

[0045] Specifically, the annular shell 222a is machined with through holes that match the workpiece sleeve 221, the threaded tube 222b is designed with four threads, and the outer wall of the push rod 222c is machined with threads. The four push rods 222c are used to clamp the four sides of the square tube workpiece, thereby fixing the square tube workpiece.

[0046] In some embodiments, such as Figure 3 As shown, the locking component 23 includes: a lug 231, which is connected to the outer periphery of the workpiece sleeve 221, and a positioning pin 232 is threadedly connected to the lug 231; and a limiting plate 233, whose inner wall is connected to the support frame 22, and threaded holes 233a are evenly distributed in the limiting plate 233, which are adapted to the positioning pin 232.

[0047] Specifically, the ear plate 231 moves together with the workpiece sleeve 221, the outer wall of the positioning pin 232 is machined with threads, the groove of the limiting plate 233 is adapted to the top protrusion of the support frame 22, and after the threaded hole 233a is connected to the positioning pin 232, it restricts the workpiece sleeve 221 from rotating in the support frame 22.

[0048] In some embodiments, such as Figure 4 As shown, the drive assembly 3 includes: a first gear 31, which is connected to the input end of the rotating shaft 211; a motor 32, the bottom end of which is connected to the drill press connecting seat 1, and the output end of which is connected to a drive shaft 33, with the end of the drive shaft 33 away from the motor 32 rotatably connected to the drill press connecting seat 1; and a second gear 34, the center hole of which is connected to the drive shaft 33, and the second gear 34 meshing with the first gear 31.

[0049] Specifically, the first gear 31 is used to drive the rotating shaft 211 to rotate in the drill press connecting seat 1. The motor 32 is a servo motor. The motor 32 is connected to the drive shaft 33 through a coupling. The drive shaft 33 is used to drive the second gear 34 to rotate. The rotation of the rotating disk 21 is driven by the transmission between the first gear 31 and the second gear 34.

[0050] In some embodiments, such as Figure 3 and Figure 4 As shown, a groove 21a is provided in the rotary disk 21, and an abutment 4 is disposed in the groove 21a. The abutment 4 is used to restrict the rotation of the rotary disk 21. The abutment 4 includes a screw 41, which is located in the groove 21a. One end of the screw 41 is connected to the drill press connecting seat 1, and the other end of the screw 41 is provided with a nut 42.

[0051] Specifically, the slide groove 21a is adapted to the screw 41, the screw 41 is used to constrain the rotation angle of the rotating disk 21, and the rotating nut 42 is fitted with the rotating disk 21 to restrict the rotation of the rotating disk 21.

[0052] In some embodiments, such as Figure 3 As shown, the rotating disk 21 has a grinding groove on the side near the nut 42. The grinding groove is used to increase the friction between the rotating disk 21 and the nut 42.

[0053] Specifically, the roughness of the rotating disk 21 is increased by designing grooves on the side of the rotating disk 21 to increase the friction between the nut 42 and the rotating disk 21.

[0054] In some embodiments, such as Figure 5 As shown, connecting plates 5 are distributed at the four corners of the drill press connecting seat 1, and through holes are provided in the connecting plates 5.

[0055] Specifically, there are four connecting plates 5, which are used to connect the drilling machine connecting seat 1 and the worktable of the radial drilling machine. In addition, there is no specific limit to the number of connecting plates 5 used.

[0056] In some embodiments, such as Figure 2 As shown, the top rod 222c is equipped with a knob 222d, and the outer periphery of the knob 222d is machined with anti-slip texture.

[0057] Specifically, the knob 222d is used to drive the push rod 222c to move in the threaded tube 222b, and anti-slip texture is machined on the outer periphery of the knob 222d to increase the friction between it and the hand.

[0058] The working principle of this application is illustrated below with a preferred embodiment:

[0059] The entire mechanism is installed on the worktable of the radial drilling machine by connecting plates 5 at the four corners of the drilling machine connecting seat 1. Then, the square tube workpiece is inserted into the inner cavity of the workpiece sleeve 221. Then, the knob 222d is turned to drive the push rod 222c to move in the threaded tube 222b towards the square tube workpiece. By adjusting the position of the push rod 222c in the threaded tube 222b one by one, the square tube workpiece is clamped in four directions (up, down, left, right). Then, the radial drilling machine is used to drill holes in the square tube workpiece by rotation and lifting.

[0060] When it is necessary to drill holes on the side of the square tube workpiece, the positioning pin 232 in the rotating ear plate 231 is separated from the limiting plate 233. Then, the workpiece sleeve 221 is rotated on the top of the support frame 22. The workpiece sleeve 221 drives the clamping part 222 and the workpiece to rotate 90 degrees together, so that the plane of the square tube workpiece to be drilled corresponds to the drill bit of the radial drilling machine. Then, the positioning pin 232 is rotated and inserted into the corresponding threaded hole 233a of the limiting plate 233, thereby locking the position of the workpiece sleeve 221 in the support frame 22. Then, the side of the square tube workpiece is drilled by the radial drilling machine.

[0061] When it is necessary to machine a slanted hole in a square tube workpiece, rotate the nut 42 to separate it from the side of the rotary disk 21, and then start the motor 32. The output end of the motor 32 drives the drive shaft 33 to rotate through the coupling. The drive shaft 33 drives the first gear 31 to rotate through the second gear 34. Under the action of the first gear 31, the rotary disk 21 is driven to rotate through the rotating shaft 211. The screw 41 in the rotary disk 21 moves in the slide groove 21a. The rotary disk 21 drives the workpiece to tilt through the support frame 22. After the tilt angle of the workpiece is adjusted appropriately, the rotary disk 21 is re-locked with the nut 42. At this time, the drill bit of the radial drilling machine is vertically downward to machine a slanted hole in the tilted square tube workpiece.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
