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

[0043] In this embodiment, as Figure 1 and Figure 2As shown, an angle adjustment device for a radial drilling machine includes: a support plate 2 located on the top surface of a radial drilling machine base 1, connected to the base 1 via a hinge assembly 3, and an integrally formed support portion 23 at the top of the support plate 2; a limiting cylinder 21 with annularly distributed toothed grooves 211 in its inner cavity, and connected to the support portion 23 on its outer periphery; a plug-in block 22 inserted into the inner cavity of the limiting cylinder 21, with teeth 221 evenly distributed on its outer periphery, the teeth 221 and the toothed grooves 211 being compatible; and a workpiece mounting frame 4 connected to the plug-in block 22 via a crossbar 41, with a clamping member 42 configured in the workpiece mounting frame 4 for clamping the workpiece.

[0044] Thus, the workpiece is installed in the workpiece mounting frame 4 by clamping member 42. At this time, the radial drilling machine can drill holes on the upper surface of the workpiece. The workpiece mounting frame 4 is moved laterally, and the insertion block 22 and the limiting cylinder 21 are separated by the crossbar 41. After rotating the workpiece mounting frame 4 clockwise or counterclockwise to the preset angle, the insertion block 22 is reinserted into the limiting cylinder 21, and then the teeth 221 are inserted into the corresponding tooth grooves 211. At this time, the workpiece mounting frame 4 and the workpiece are in an inclined state. At this time, the radial drilling machine can process inclined holes on the workpiece. By rotating and adjusting the position of the workpiece, and cooperating with the rotation and lifting of the radial drilling machine around the column, different outer surfaces of the workpiece can be processed.

[0045] Specifically, radial drilling is a technology known to those skilled in the art. Radial drilling base 1 is part of radial drilling. Radial drilling base 1 is located at the bottom of radial drilling and supports the overall mechanism. Carrier plate 2 and radial drilling base 1 are arranged in parallel. Support part 23 is used to install limiting cylinder 21. Insertion block 22 and limiting cylinder 21 are detachable. The position of insertion block 22 in limiting cylinder 21 is adjusted by the meshing of teeth 221 and tooth groove 211. One end of carrier plate 2 is deflected on radial drilling base 1 through hinge assembly 3 to readjust the position of workpiece. Workpiece mounting bracket 4 is designed with a cavity to facilitate the falling of debris.

[0046] In some embodiments, such as Figure 2 As shown, a reset member 43 is arranged on the outer periphery of the crossbar 41; the reset member 43 includes: a right-angle plate 431, one end of which is connected to the support part 23, and the other end of which is slidably connected to the crossbar 41; and an elastic member 432, which is sleeved on the outer periphery of the crossbar 41, one end of which abuts against the insertion block 22, and the other end of which abuts against the right-angle plate 431.

[0047] Specifically, the right-angle plate 431 has through holes that are compatible with the crossbar 41, allowing the crossbar 41 to rotate within the right-angle plate 431. The elastic element 432 facilitates the driving of the insertion block 22 into the limiting cylinder 21.

[0048] In some embodiments, such as Figure 3 As shown, the clamping component 42 includes: a drive shaft 421, which is connected to the workpiece mounting frame 4 via bearings; a crossbeam 422, one end of which is slidably connected to a guide rod 422a, both ends of which are connected to the workpiece mounting frame 4, and the other end of which is equipped with a slide block 422b, which is internally threaded to the drive shaft 421; the drive shaft 421 and the guide rod 422a are arranged parallel to each other; a first clamping plate 423, the bottom end of which is fixedly connected to the crossbeam 422; and a second clamping plate 424, which is connected to the workpiece mounting frame 4 and is arranged parallel to the first clamping plate 423.

[0049] Specifically, the drive shaft 421 is located in the groove of the workpiece mounting bracket 4. The drive shaft 421 and the guide rod 422a are symmetrically distributed based on the crossbeam 422. The slide block 422b is designed to drive the crossbeam 422 to move. The bottom of the first clamping plate 423 and the second clamping plate 424 are both machined with raised edges to support the workpiece. In addition, the clamping member 42 can be replaced by other clamps.

[0050] In some embodiments, such as Figure 3 As shown, the second clamping plate 424 has a V-groove machined on the side near the first clamping plate 423. The V-groove is used to clamp the rod-shaped workpiece.

[0051] Specifically, the V-groove in the second clamping plate 424 facilitates the clamping of rod-shaped workpieces. Multiple V-grooves can be designed to facilitate the clamping of multiple rods.

[0052] In some embodiments, such as Figure 4 and Figure 5 As shown, the hinge assembly 3 includes: a rotating roller 31, the outer periphery of which is connected to the end of the bearing plate 2 away from the limiting cylinder 21; two foot plates 32, which are rotatably connected to the rotating roller 31 via pins, and the bottom ends of the two foot plates 32 are connected to the radial drilling base 1; and a locking member 33, which is used to lock the rotation angle of the rotating roller 31 to lock the tilt angle of the workpiece.

[0053] Specifically, the rotating roller 31 is used to drive the bearing plate 2 to shift. The two foot plates 32 are located on the same axis. The rotating roller 31 can rotate between the two foot plates 32. The rotation angle of the rotating roller 31 is locked by the locking member 33 to fix the tilt angle of the bearing plate 2 on the radial drilling base 1.

[0054] In some embodiments, such as Figure 5As shown, the locking component 33 includes: a guard plate 331, the bottom end of which is connected to the radial drilling base 1, and the guard plate 331 is connected to the rotating roller 31 by bolts 332; a reinforcing rib 333 is provided at the angle between the guard plate 331 and the radial drilling base 1.

[0055] Specifically, the top of the guard plate 331 is machined into an arc shape to match the outer diameter of the rotating roller 31, and the reinforcing rib 333 is designed to increase the connection strength between the guard plate 331 and the radial drilling base 1.

[0056] In some embodiments, such as Figure 5 As shown, the outer circumference of the rotating roller 31 is evenly distributed with slots, which are adapted to the bolts 332;

[0057] Specifically, the slots are distributed in a ring along the rotating roller 31, and the position of the rotating roller 31 is adapted to the bolt 332. The bolt 332 is inserted into the corresponding slot to fix the position of the rotating roller 31 after rotation.

[0058] In some embodiments, such as Figure 2 As shown, the elastic element 432 is a compression spring.

[0059] Specifically, the elastic element 432 adopts a compression spring design to apply external force to the insertion block 22 in the limiting cylinder 21 to prevent the insertion block 22 from accidentally falling out of the limiting cylinder 21.

[0060] The working principle of this application is illustrated below with a preferred embodiment:

[0061] The workpiece is placed between the first clamping plate 423 and the second clamping plate 424. The drive shaft 421 is rotated to move the slide block 422b. The slide block 422b drives the crossbeam 422 to move around the guide rod 422a. At the same time, the first clamping plate 423 moves with the crossbeam 422 to the side closer to the second clamping plate 424, thereby clamping the workpiece. A radial drill is used to drill a hole in the top of the workpiece.

[0062] When it is necessary to adjust the processing position of the workpiece, first move the workpiece mounting frame 4 laterally. The workpiece mounting frame 4 drives the insertion block 22 and the limiting cylinder 21 to separate through the crossbar 41. At the same time, the insertion block 22 compresses the elastic element 432 on the outer periphery of the crossbar 41. After rotating the workpiece mounting frame 4 clockwise or counterclockwise to the preset angle, the insertion block 22 is reinserted into the limiting cylinder 21, and then the teeth 221 are inserted into the corresponding tooth grooves 211. At this time, the workpiece mounting frame 4 and the workpiece are in an inclined state, and the radial drilling machine processes the inclined hole on the workpiece.

[0063] Depending on the usage requirements, with the workpiece mounting frame 4 in an inclined state, the rotating roller 31 is rotated between the two foot plates 32. The rotating roller 31 drives the bearing plate 2 to deflect twice, resulting in an angle between the bearing plate 2 and the radial drilling base 1. Then, the bolt 332 in the guard plate 331 is rotated to connect with the corresponding slot on the surface of the rotating roller 31 to fix the inclination angle of the bearing plate 2, thereby performing drilling processing on the workpiece at different positions.

[0064] 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.
