Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a positioning and adjustment device for machining irregularly shaped structural parts. Background Technology

[0002] In machining, the blank material needs to be clamped stably before machining on a machine tool. However, 3D printed blanks have less allowance, especially for irregularly shaped workpieces. The surface of the blank material is uneven. Directly pressing the workpiece onto the worktable for processing can cause the workpiece to swing down or up in some places, which can easily lead to unstable clamping and dimensional deviations, and in severe cases, the workpiece may be scrapped.

[0003] Therefore, a technical solution is needed to address the problem that irregularly shaped workpiece blanks with uneven surfaces may exhibit localized downward or upward tilting on the worktable, easily leading to dimensional deviations and workpiece scrap. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problem that irregularly shaped workpiece blanks with uneven surfaces will partially swing down or up on the worktable, which easily leads to dimensional deviations and workpiece scrapping. This invention provides a positioning and adjustment device for processing irregularly shaped structural parts.

[0005] This utility model provides a positioning and adjustment device for processing irregular structural parts, including a base and a mounting plate. A support block is provided between the base and the mounting plate. The mounting plate is used to abut against the irregular structural parts. The mounting plate is provided with a plurality of threaded through holes, and each threaded through hole is equipped with an adjustment bolt.

[0006] This utility model discloses a positioning and adjustment device for machining irregularly shaped structures. In use, the base is placed on the machining table and fixed to the machining table. The irregularly shaped structural part is placed on the mounting plate. The adjusting bolt on the bottom surface of the mounting plate is rotated to lift the lower swing area of ​​the workpiece, thereby fine-tuning the bottom height of the workpiece. This allows the workpiece to maintain the correct posture for machining, thereby improving the machining quality of irregularly shaped structural parts and reducing the scrap rate.

[0007] Preferably, a plurality of the threaded through holes are provided around the edge of the mounting plate.

[0008] A ring of threaded through holes is provided around the mounting plate. The vertical position of the workpiece can be adjusted by adjusting bolts in each threaded through hole, thereby addressing the tilting problem of the workpiece in various directions.

[0009] Preferably, it also includes at least two limiting mechanisms, all of which are disposed on both sides of the mounting plate and are used to abut against the side walls of the irregular structural component.

[0010] At least two limiting mechanisms push against both sides of the workpiece, thereby clamping the workpiece between the two limiting mechanisms and thus creating a horizontal limit on the workpiece.

[0011] Preferably, the limiting mechanism includes a stop block, which is detachably connected to the side wall of the mounting plate. The stop block is provided with a limiting screw hole, and the limiting screw hole is equipped with a limiting bolt.

[0012] After the workpiece is placed on the mounting plate, it is leveled by adjusting bolts. Then, the stop block is detachably connected to the side wall of the mounting plate by bolts. Rotating the limit bolt on the stop block tightens the limit bolt against the side wall of the workpiece, thereby achieving horizontal positioning of the workpiece on the mounting plate.

[0013] Preferably, both the adjusting bolt and the limiting bolt are fitted with anti-loosening nuts.

[0014] During the machining process, the workpiece vibrates due to the force of the cutting tool. By installing anti-loosening nuts on the limiting bolts and adjusting bolts that restrict the movement of the workpiece, the loosening of the limiting bolts and adjusting bolts can be prevented, thus ensuring the stability of the workpiece's posture during the machining process.

[0015] Preferably, the number of limiting mechanisms is four, and the four limiting mechanisms are symmetrically arranged on both sides of the mounting plate.

[0016] The symmetrical setting of limiting mechanisms on both sides of the mounting plate can balance the force on both sides of the workpiece, making the workpiece clamping more stable. At the same time, two limiting mechanisms are set on each side of the mounting plate. The two limiting mechanisms can limit the workpiece within a certain length range, preventing the workpiece from rotating or swinging in the horizontal direction, and making the workpiece clamped more securely.

[0017] Preferably, it further includes a clamping mechanism, which includes a pressure plate, a clamping screw hole provided on the pressure plate, a clamping bolt disposed in the clamping screw hole, and a connecting screw hole adapted to the clamping bolt provided on the mounting plate.

[0018] The pressure plate has mating surfaces on both sides that are adapted to the shape of the workpiece. The pressure plate is placed in the hole or other window on the workpiece through which the clamping bolt can pass. The two sides of the pressure plate are mated to the workpiece. The clamping bolt is inserted through the window on the workpiece and connected to the connecting screw hole on the mounting plate, thereby pulling the pressure plate tight to the surface of the workpiece, thus achieving the clamping of the workpiece on the mounting plate.

[0019] Preferably, the base is provided with a plurality of connection holes.

[0020] Several connecting holes are arranged around the edge of the base to avoid the support blocks on the base. Bolts are inserted into the connecting holes and connected to the processing table, thereby fixing the base to the processing table.

[0021] Preferably, a light-reducing cavity is provided at the bottom of the base.

[0022] By ensuring that the base has sufficient support strength, a weight-reducing cavity can be set on the bottom surface of the base to significantly reduce the weight of the entire device, making it easier to transport, install and disassemble.

[0023] Preferably, the mounting plate has an avoidance notch.

[0024] When there is a protrusion or other structure that interferes with the mounting plate on the side of the workpiece that abuts against the mounting plate, an avoidance notch is provided on the mounting plate so that the structure that interferes with the mounting plate can be embedded in the avoidance notch, thereby allowing the workpiece to fit against the mounting plate.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. This utility model provides a positioning and adjustment device for processing irregular structural parts. By adjusting the adjustment bolts set on the bottom surface of the mounting plate, the lower swing area of ​​the workpiece can be pushed upward to finely adjust the bottom height of the workpiece, so that the workpiece can maintain the correct posture for processing, thereby improving the processing quality of irregular structural parts and reducing the scrap rate.

[0027] 2. This utility model provides a positioning and adjustment device for processing irregular structural parts. The workpiece posture can be adjusted simply by rotating the adjusting bolt at the corresponding position. The operation is simple and improves the clamping efficiency of irregular structural parts.

[0043] Example 1

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a positioning and adjustment device for processing irregular structural parts includes a base 1 and a mounting plate 2. A support block 3 is provided between the base 1 and the mounting plate 2. The support block 3 is located in the middle of the base 1 and the mounting plate 2. A gap is formed between the side wall of the mounting plate 2 and the side wall of the support block 3. The upper surface of the mounting plate 2 is used to abut against the irregular structural part 8. The mounting plate 2 is provided with a plurality of threaded through holes 21. The plurality of threaded through holes 21 are arranged around the edge of the mounting plate 2. Each threaded through hole 21 is equipped with an adjustment bolt 4 to ensure that the bottom surface of the irregular structural part 8 can be finely adjusted in height by adjusting the bolt 4.

[0045] In use, place the base 1 on the processing table and fix it to the processing table. Place the irregular structural part 8 on the mounting plate 2, rotate the adjusting bolt 4 on the bottom surface of the mounting plate 2, and lift the lower swing area of ​​the workpiece by adjusting the adjusting bolt 4, thereby making a fine adjustment to the bottom height of the workpiece so that the workpiece can maintain the correct posture for processing, thereby improving the processing quality of the irregular structural part 8 and reducing the scrap rate.

[0046] Base 1: A positioning hole 9 is provided in the middle of the base 1. The positioning hole 9 passes through the support block 3 and the mounting plate 2. The positioning hole 9 of the base 1 is connected to the positioning shaft of the processing table. Several connecting holes 11 are provided around the edge of the base 1. The position of the connecting holes 11 should avoid the support block 3 on the base 1. Bolts are inserted into the connecting holes 11 and connected to the processing table, thereby fixing the base 1 to the processing table. Furthermore, while ensuring that the base 1 has sufficient support strength, a light-reducing cavity 12 is provided on the bottom surface of the base 1, which can significantly reduce the weight of the entire device and facilitate the transportation, installation and disassembly of the device.

[0047] Example 2

[0048] like Figure 1 , Figure 4 and Figure 7 As shown, the difference between this embodiment and embodiment 1 is that it also includes at least two limiting mechanisms 5. All the limiting mechanisms 5 are disposed on both sides of the mounting plate 2 and are used to abut against the side walls of the irregular structural component 8.

[0049] In this embodiment, at least two limiting mechanisms 5 respectively abut against both sides of the workpiece, thereby clamping the workpiece between the two limiting mechanisms 5, thus forming a horizontal limit on the workpiece.

[0050] Limiting mechanism 5: includes a stop block 51, which is detachably connected to the side wall of the mounting plate 2. The stop block 51 is provided with a limiting screw hole, and a limiting bolt 52 is provided in the limiting screw hole. After the workpiece is placed on the mounting plate 2, the workpiece is leveled by adjusting bolt 4. Then, the stop block 51 is detachably connected to the side wall of the mounting plate 2 by bolt. By rotating the limiting bolt 52 on the stop block 51, the limiting bolt 52 is pressed against the side wall of the workpiece, thereby realizing the horizontal limiting of the workpiece on the mounting plate 2.

[0051] Furthermore, during the machining process, the workpiece vibrates due to the force of the cutting tool. By installing anti-loosening nuts 6 on the limiting bolts 52 and adjusting bolts 4 that restrict the movement of the workpiece, the limiting bolts 52 and adjusting bolts 4 can be prevented from loosening, thus ensuring the stability of the workpiece's posture during the machining process.

[0052] Furthermore, there are four limiting mechanisms 5, which are symmetrically arranged on both sides of the mounting plate 2. The symmetrical arrangement of the limiting mechanisms 5 on both sides of the mounting plate 2 can balance the force on both sides of the workpiece, making the workpiece clamping more stable. At the same time, two limiting mechanisms 5 are respectively arranged on both sides of the mounting plate 2. The two limiting mechanisms 5 can limit the workpiece within a certain length range, preventing the workpiece from rotating or swinging in the horizontal direction, and making the workpiece clamped more securely.

[0053] Example 3

[0054] like Figure 1 and Figure 5 As shown, the difference between this embodiment and embodiment 1 is that it also includes a clamping mechanism 7. The clamping mechanism 7 includes a pressure plate 71, a clamping screw hole 711 is provided on the pressure plate 71, a clamping bolt 72 is provided in the clamping screw hole 711, and the mounting plate 2 is provided with a connecting screw hole 22 that is adapted to the clamping bolt 72.

[0055] In this embodiment, the pressure plate 2 has mating surfaces on both sides that are adapted to the shape of the workpiece. The pressure plate 2 is placed in the hole or other window on the workpiece through which the clamping bolt 72 can pass. The two sides of the pressure plate 71 are mated to the workpiece. The clamping bolt 72 is inserted through the window on the workpiece and connected to the connecting screw hole 22 on the mounting plate 2, thereby pulling the pressure plate 71 tight to the surface of the workpiece, thus realizing the clamping of the workpiece on the mounting plate 2.

[0056] Example 4

[0057] like Figure 1 and Figure 7 As shown, in this embodiment, the difference from embodiment 1 is that the mounting plate 2 is provided with an avoidance notch 23.

[0058] In this embodiment, when there is a protrusion or other structure that interferes with the mounting plate 2 on the side of the workpiece that abuts against the mounting plate 2, by providing an avoidance notch 23 on the mounting plate 2, the structure on the workpiece that interferes with the mounting plate 2 can be embedded in the avoidance notch 23, thereby allowing the workpiece to fit onto the mounting plate 2.

[0059] In this example, the irregular structural component 8 has downward-facing lugs 81 on both sides. Therefore, clearance notches 23 are provided on both sides of the mounting plate 2 so that the lugs 81 of the irregular structural component 8 can be embedded in the clearance notches 23. At the same time, a waist-shaped groove 24 is provided on the inner wall of the clearance notch 23. The waist-shaped groove 24 corresponds to the lug hole 82 on the lug 81. During the finishing process, the relative stability between the irregular structural component 8 and the mounting plate 2 can be strengthened by the pin.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
