Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece processing tooling technology, and more specifically, to a forming tooling for columnar spiral curved surface parts. Background Technology
[0002] There are two main methods for manufacturing cylindrical helical curved surface workpieces: one is die pressing, and the other is machining using a machining center. Both methods can produce workpieces with high dimensional accuracy, but they are costly, require machining centers, and are difficult to manufacture. For workpieces with low surface accuracy and small batch sizes, the manufacturing cost becomes too high and the efficiency is low. Utility Model Content
[0003] The purpose of this invention is to provide a forming fixture for cylindrical helical curved surface parts, which solves the problems of high processing difficulty and low efficiency of existing helical curved surface workpieces.
[0004] This utility model is achieved through the following technical solution: a forming fixture for columnar spiral curved surface parts, including a base, a fixed block at one end of the base, a slider slidably connected to the other end of the base, a first clamping part rotatably connected to the fixed block, a rotating handle provided on the first clamping part, and a second clamping part provided on the slider. The first clamping part and the second clamping part cooperate to clamp the two ends of the workpiece respectively.
[0005] Furthermore, the fixed block is evenly provided with several limiting holes along the circumference of the first clamping part, and a limiting rod that abuts against the rotating handle is threaded into the limiting hole.
[0006] Furthermore, the first clamping part includes a rotating shaft and a first clamping plate. The rotating shaft is connected to the stationary block via a bearing, and the first clamping plate is bolted to the rotating shaft.
[0007] Furthermore, the second clamping part includes a second clamping plate that is bolted to the slider.
[0008] Furthermore, the slider is threadedly connected with locking bolts for locking the relative position of the slider and the base.
[0009] Furthermore, scale lines are provided around the first clamping part of the fixed block.
[0010] Furthermore, the handle is equipped with anti-slip texture.
[0011] This utility model has at least the following advantages and beneficial effects:
[0012] (1) By cooperating with the fixed block and the slider on the base, the first clamping part on the fixed block is rotated to clamp one end of the workpiece, and the second clamping part on the slider is clamped to clamp the other end of the workpiece. Then, the rotating handle is turned to make the first clamping part rotate, thereby twisting it into a spiral curved surface workpiece. The operation is simple and convenient, and the forming efficiency is improved.
[0013] (2) By uniformly opening several limiting holes along the circumference of the first clamping part on the fixed block, and connecting the limiting rod that abuts against the rotating handle with the thread in the limiting hole, the torsion angle of the workpiece is effectively controlled to adapt to the processing of workpieces of different specifications and shapes, thereby improving the accuracy and flexibility of workpiece processing.

Detailed Implementation
[0016] The specific implementation method is described below with reference to the accompanying drawings.
[0017] Example
[0018] like Figure 1 As shown in the figure, this embodiment mainly discloses a forming fixture for columnar helical curved surface parts. The fixture has a simple and reliable structure, including a base 1, a fixed block 2 at one end of the base 1, and a slider 3 slidably connected to the other end of the base 1. A first clamping part 4 is rotatably connected to the fixed block 2, and a rotating handle 6 is provided on the first clamping part 4. A second clamping part 5 is provided on the slider 3. The first clamping part 4 and the second clamping part 5 cooperate to clamp the two ends of the workpiece 7 respectively. Specifically, the base 1 is fixed to a stable plane by bolts, providing stable support and ensuring stability during clamping. The fixed block 2 is welded and fixed to one end of the upper surface of the base 1, while the slider 3 achieves a sliding connection with the base 1 through a slot. During processing of the workpiece 7, one end of the workpiece 7 is clamped by the first clamping part 4, and the other end is clamped by the second clamping part 5. Then, the rotating handle 6 is turned to rotate the first clamping part 4, thereby twisting it into a helical curved surface workpiece 7. In addition, to facilitate the processing of workpiece 7, an induction heating coil, a technology already in use, can be used to heat the workpiece 7 blank to a dark red state, and then the handle 6 can be turned. The operation is simple and convenient, improving the forming efficiency.
[0019] Furthermore, in a specific implementation, the aforementioned fixed block 2 provided in this embodiment of the present invention has a plurality of limiting holes 20 evenly opened around the first clamping part 4, and the limiting holes 20 are internally threaded with limiting rods 21 that abut against the rotating handle 6. Specifically, during operation, two limiting rods 21 can be used in conjunction, that is, the two limiting rods 21 correspond to the initial torsion position of the workpiece 7 blank and the expected torsion angle position of the workpiece 7, respectively. Through the cooperation of the limiting rods 21 and the limiting holes 20, the torsion angle of the workpiece 7 is effectively controlled to adapt to the processing of workpieces 7 of different specifications and shapes, thereby improving the accuracy and flexibility of the workpiece 7 processing.
[0020] Furthermore, in a specific implementation, the first clamping part 4 provided in this embodiment of the present invention includes a rotating shaft 41 and a first clamping plate 42. The rotating shaft 41 is connected to the fixed block 2 via a bearing, and the first clamping plate 42 is bolted to the rotating shaft 41. Specifically, the rotating handle 6 is arranged radially along the rotating shaft 41, and the end of the rotating shaft 41 is provided with a clamping groove 410 for cooperating with the first clamping plate 42 to clamp the workpiece 7. The first clamping plate 42 is bolted to the surface of the clamping groove 410, which improves working efficiency and ease of operation.
[0021] Furthermore, in a specific implementation, the second clamping part 5 provided in this embodiment of the present invention includes a second clamping plate 51 bolted to the slider 3. The second clamping plate 51 is detachably connected to the top of the slider 3 by bolts.
[0022] Furthermore, in a specific implementation, the slider 3 provided in this embodiment of the present invention is threadedly connected with a locking bolt 31 for locking the relative position of the slider 3 and the base 1. Specifically, the locking bolt 31 is threadedly connected to the side of the slider 3 and abuts against the side of the base 1, ensuring the stability of the position between the slider 3 and the base 1, preventing accidental loosening during processing, and effectively improving the forming quality.
[0023] Furthermore, in a specific implementation, the aforementioned fixed block 2 provided in this embodiment of the invention has scale lines circumferentially arranged on the first clamping part 4. This provides the operator with a visual adjustment reference, facilitating quick positioning and adjustment of the operating angle of the rotating handle 6, and improving the intuitiveness and efficiency of the operation.
[0024] Furthermore, in a specific implementation, the rotating handle 6 provided in this embodiment of the invention is provided with anti-slip texture. This can effectively increase the friction of the rotating handle 6, avoid instability in clamping caused by hand slippage during operation, and improve the safety and reliability of operation.
