Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to an arc-shaped guide discrete angle orthogonal switching processing device. Background Technology

[0002] In the machinery manufacturing industry, workpiece drilling is a very common and widespread process. Currently, the most widely used equipment is the machining center, which is generally divided into vertical and horizontal types. The two have different working paths and can meet the machining needs of different precision. However, in daily machining activities, it is sometimes necessary to drill different sides of the workpiece or at a certain angle, and it is necessary to ensure the machining quality. However, the existing machining centers, whether vertical or horizontal, have a single machining path. Machining different sides of the workpiece or at a certain angle can only be achieved by adjusting the position of the workpiece. Because it requires secondary clamping, it is very easy to cause errors. Therefore, designing a device that can perform drilling operations on different sides of the workpiece without adjusting the position of the workpiece is particularly important for the entire machinery manufacturing industry.

[0020] like Figure 1 The diagram shown is a structural schematic of an arc-shaped guide discrete angle orthogonal switching processing device according to one embodiment of the present invention. Figure 2 The diagram shown is a schematic representation of a horizontal machining structure of an arc-guided discrete angle orthogonal switching machining device according to an embodiment of the present invention; Figure 1 The processing device includes a base 1, a clamping mechanism 2, an arc-shaped frame 3, a cutting mechanism 4, and an adjustment drive mechanism 5. Specifically, the base 1 has a cavity 11, the clamping mechanism 2 is located on the top of the base 1, the arc-shaped frame 3 is located on the top of the base 1 and is located on one side of the clamping mechanism 2 to surround the clamping mechanism 2. The center of the arc-shaped frame 3 is located on the horizontal axis of the clamping mechanism 2. The cutting mechanism 4 is slidably connected to the arc-shaped frame 3 to surround the side of the clamping mechanism 2. The adjustment drive mechanism 5 is located in the cavity 11, and the top of the adjustment drive mechanism 5 extends out of the base 1 and is fixedly connected to the cutting mechanism 4 to adjust and drive the cutting mechanism 4 to slide on the arc-shaped frame 3.

[0021] exist Figure 1 , 2In order to adapt to the processing needs of different positions of slender workpieces, considering that the longitudinal movement range of the cutting mechanism 4 is fixed, it is necessary to adjust the workpiece laterally to align with the cutting mechanism 4 for processing and expand the processing range. In one embodiment of this utility model, the clamping mechanism 2 may include a first section 21, a second section 22 and a lock 23. The first section 21 is disposed on the top of the base 1, the second section 22 is slidably connected to the first section 21, and the sliding direction of the second section 22 is perpendicular to the feed direction of the cutting mechanism 4. The lock 23 is disposed at both ends of the top of the second section 22 for clamping and locking the workpiece. As long as the second section 22 is pushed to slide on the first section 21, the longitudinal position of the workpiece is kept fixed, so that the workpiece can be moved laterally without being disassembled, thereby enabling processing operations at different positions and avoiding re-clamping.

[0022] exist Figure 1 In this invention, considering the size and fixing requirements of the first section 21 and the second section 22, and in order to reduce costs while ensuring safe use, in one embodiment of the present invention, the length of the first section 21 is not less than half the length of the second section 22 to avoid center of gravity shift.

[0023] exist Figure 1 In order to enable the cutting mechanism 4 to move along a certain arc-shaped trajectory on the arc-shaped frame 3, in one embodiment of this utility model, the arc-shaped frame 3 includes a through groove 31 and two sets of guide grooves 32. The through groove 31 is arranged radially along the arc-shaped frame 3 to facilitate the subsequent movement of the cutting mechanism 4 on the through groove 31. The two sets of guide grooves 32 are correspondingly arranged on both sides of the through groove 31, and the curvature of the guide grooves 32 is the same as the curvature of the arc-shaped frame 3, so that the cutting mechanism 4 slides along the guide grooves 32, thereby enabling the cutting mechanism 4 to shift to one side of the workpiece.

[0024] exist Figure 1 In this embodiment of the invention, considering the processing of one side of the workpiece, the central angle of the arc frame 3 is 90°, and the top of the arc frame 3 is located above the clamping mechanism 2. This makes the central angle of the arc frame 3 90° when the cutting mechanism 4 is in a horizontal state, and the top of the arc frame 3 is located above the clamping mechanism 2, which restricts the range of motion of the cutting mechanism 4. When it is in the horizontal direction, it is a horizontal processing mode, and when it is in the vertical direction, it is a vertical processing mode.

[0025] like Figure 3 The diagram shown is a cross-sectional structural schematic of an arc-shaped guide discrete angle orthogonal switching processing device according to one embodiment of the present invention; Figure 1 , 2In addition to step 3, in order to achieve the processing of the workpiece and ensure the connection between the cutting mechanism 4 and the adjustment drive mechanism 5, in one embodiment of this utility model, the cutting mechanism 4 includes a support plate 41, a track base 421 and a tool holder 43. The support plate 41 is fixedly disposed on the top of the adjustment drive mechanism 5, the track base 421 is fixedly disposed on the top of the support plate 41, and the tool holder 43 is slidably disposed on the top of the track base 421. The tool holder 43 can perform tool advance and retraction on the track base 421, while the support plate 41 can be connected to the adjustment drive mechanism 5 to avoid direct connection to the track base 421.

[0026] exist Figure 1 , 2 In addition to the above, considering the range of motion of the cutting mechanism 4, it performs horizontal processing when in the horizontal direction and vertical processing when in the vertical direction. The cutting mechanism 4 can also perform processing when it is in the middle of the arc-shaped frame 3. In one embodiment of this utility model, a locking tongue 431 is provided on the top of the tool holder 43, and multiple sets of locking holes are provided on the locking tongue 431; a locking buckle 432 that matches and connects to the locking holes is provided on the top of the arc-shaped frame 3, so that during processing, the upper support of the drive mechanism 5 and the lower pull of the locking holes and locking buckle 432 are adjusted to ensure that the cutting mechanism 4 is in a stable state on the arc-shaped frame 3, thus achieving the processing requirements.

[0027] like Figure 4 The diagram shown is a schematic representation of the clamping mechanism and a portion of the internal structure of a curved guide discrete angle orthogonal switching processing device according to one embodiment of the present invention. Figure 4 In order to achieve arc-shaped movement of the cutting mechanism 4 on the arc-shaped frame 3, in one embodiment of this utility model, the adjusting drive mechanism 5 includes a drive device 51, a gear 52, an arc plate 53, and multiple sets of teeth 54. The drive device 51 is disposed in the cavity 11, the gear 52 is disposed on the output shaft of the drive device 51, the arc plate 53 is disposed in the cavity 11, one end of the arc plate 53 passes through the opening 12 on the upper surface of the base 1 and is connected to the support plate 41, and the symmetry plane of the arc plate 53 and the symmetry plane of the arc-shaped frame 3 are located on the same plane as the vertical clamping mechanism 2. Multiple sets of teeth 54 are evenly distributed on the arc plate 53 and mesh with the gear 52 for transmission. When the output shaft of the drive device 51 rotates, the gear 52 drives the teeth 54 to move, so that the arc plate 53 can pass through the opening 12 and push the support plate 41 to move upward, ensuring that the cutting mechanism 4 moves on the through groove 31.

[0028] exist Figure 1 In this invention, considering the limiting sliding of the cutting mechanism 4 and ensuring the stability of the arc sliding, in one embodiment of the present invention, sliders 411 are provided at both ends of the support plate 41. The sliders 411 are matched and slidably connected with the guide groove 32, so that the sliders 411 can limit the arc sliding of the cutting mechanism 4 and ensure safety.

[0029] exist Figure 2 , 3 In addition to section 4, to prevent the cutting mechanism 4 from falling into the cavity 11 and to ensure a safe operating environment for the cutting mechanism 4, in one embodiment of this utility model, the projected area of ​​the support plate 41 is larger than the area of ​​the opening 12, and a flexible pad (not shown in the figure) is provided at the bottom of the support plate 41. This ensures that the support plate 4 can perform horizontal processing when the cutting mechanism 4 is in a horizontal direction, and the flexible pad at the bottom of the support plate 41 reduces the impact generated by movement and protects the cutting mechanism 4.

[0030] Through the above technical solution, the processing device is set on a base with a cavity inside. The clamping mechanism is set on the top of the base, and a second section is set on the clamping mechanism to adjust the sliding of the workpiece, which facilitates the horizontal movement of the workpiece and realizes multi-area processing of large workpieces. An arc-shaped frame is set on the top of the base and is set on one side of the clamping mechanism to surround the clamping mechanism. The adjustment drive mechanism can be set in the cavity. The top of the adjustment drive mechanism passes through the base and connects to the support plate to fix it to the cutting mechanism. Sliders are set at both ends of the support plate and are slidably connected in the guide groove. The tool holder slides along the guide groove in the through groove and is connected to the arc-shaped frame to surround the side of the clamping mechanism. This allows the cutting mechanism to perform multi-directional processing of the workpiece on the clamping mechanism, avoids clamping errors caused by secondary clamping of the workpiece, and thus greatly improves the positional accuracy of the processing.
