Technical Field

[0001] This utility model relates to the field of tooling fixture technology, and more specifically, to a novel fast multi-station tooling fixture. Background Technology

[0002] Tooling fixtures are core auxiliary devices in the processing and assembly stages of manufacturing. Their core function is to accurately fix the position of the workpiece, ensure processing accuracy and operational safety, and are key equipment for improving production efficiency.

[0003] Currently, most tooling fixtures on the market are single-station fixtures that require repeated clamping, resulting in low efficiency in mass production. Traditional multi-station fixtures are mostly designed with fixed angles, which cannot adapt to workpieces with different machining angle requirements, resulting in poor versatility. Some multi-station fixtures have complex clamping structures, rely on tool operation, and are time-consuming to clamp, and the positioning surfaces are prone to slippage, leading to poor workpiece machining consistency. At the same time, the complex operation process requires high worker skills, increasing training costs and the risk of operational errors, making it difficult to meet the high-efficiency and precision requirements of modern mass production.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This embodiment discloses a novel rapid multi-station tooling fixture, which aims to solve the problems of poor multi-station adaptability, low clamping efficiency, and insufficient positioning accuracy of existing tooling fixtures. The specific structure is as follows: like Figure 1 As shown, the novel rapid multi-station tooling fixture of this embodiment includes a horizontally arranged base, which is integrally cast from HT200 gray cast iron. Several independent positioning components are evenly distributed along the length of the base's top, enabling simultaneous clamping and positioning of workpieces with different angle requirements, significantly improving batch processing efficiency. Each positioning component has the same core structure; the following detailed description uses a single positioning component as an example.

[0016] like Figure 2 As shown, the positioning assembly includes a mounting base 1, a connecting frame 2, a limiting rod 3, an adjusting rod 4, a stop block 5, an anti-slip toothed plate 6, a rotating cylinder 7, a limiting pin 11, a pressure plate 12, and a knob 13. The connection relationships of each component are as follows: Mounting base 1: Made of 45 steel and machined, with a mounting cavity on the top. The inner wall of the mounting cavity is inlaid with a deep groove ball bearing for rotating connection of the connecting frame 2. The connecting frame 2 is a frame structure made of forged aluminum alloy. Its bottom end extends into the mounting cavity of the mounting base 1 and is interference-fitted with the inner ring of the bearing. Figure 3 As shown, a knob 13 is welded and fixed to the bottom of the outer side wall of the connecting frame 2. The outer circumference of the knob 13 is provided with anti-slip texture. Rotating the knob 13 can drive the connecting frame 2 to rotate around the axis of the mounting cavity, so as to achieve angle adjustment within the range of 0-90°. The limiting rod 3 is horizontally positioned at the top of the inner cavity of the connecting frame 2. One end of it is hinged to the inner wall of the connecting frame 2, and the other end extends to the opening side of the connecting frame 2. Figure 3 As shown, a pin hole is provided through the side wall of the connecting frame 2. The limiting pin 11 is inserted into the connecting frame 2 through the pin hole, and one end of the limiting pin 11 passes through the corresponding through hole of the limiting rod 3 and extends to the other side of the connecting frame 2 to fix the flip angle of the limiting rod 3. At the same time, an arc-shaped pressure plate 12 is fixed to the top of the inner cavity of the connecting frame 2 by bolts. The pressure plate 12 is made of nitrile rubber, and its bottom end abuts against the upper surface of the limiting rod 3 to buffer the impact of the limiting rod 3. Adjusting rod 4 is a cuboid structure, and it is horizontally slidably connected to the middle groove of connecting frame 2, such as... Figure 4 As shown, a stop block 5 is welded and fixed to one end of the adjusting rod 4. The stop block 5 has an L-shaped structure. On the side opposite to the limiting rod 3, an anti-slip toothed plate 6 is fixed by a countersunk bolt. The surface of the anti-slip toothed plate 6 is provided with V-shaped anti-slip teeth, which can enhance the friction with the workpiece and prevent clamping slippage. like Figure 4 , Figure 5 As shown, a rotating cylinder 7 is sleeved on the outer side of the adjusting rod 4. The rotating cylinder 7 is made of brass and has a first threaded strip 8 integrally formed on its inner wall. The two side walls of the adjusting rod 4 are integrally formed with second threaded strips 9 at corresponding positions. The second threaded strips 9 mesh with the first threaded strip 8. A rectangular frame opening 10 is provided through the middle of the connecting frame 2. The two ends of the rotating cylinder 7 are rotatably connected to the inner wall of the frame opening 10 through bushings. The outer circumference of the rotating cylinder 7 is provided with a knurled structure to facilitate manual rotation operation.

[0017] The specific working principle is as follows: According to the workpiece processing angle requirements, rotate the knob 13 to drive the connecting frame 2 to rotate around the mounting cavity of the mounting base 1 until the connecting frame 2 reaches the preset angle. At this time, the pressure plate 12 abuts against the limiting rod 3 to maintain a horizontal state. Insert the limiting pin 11 through the connecting frame 2 and the limiting rod 3 to complete the angle fixation of the connecting frame 2. Place the workpiece to be processed between the limiting rod 3 and the stop block 5 so that the positioning surface of the workpiece is in contact with the anti-slip toothed plate 6. Manually rotate the drum 7. The drum 7 rubs against the second threaded bar 9 of the adjusting rod 4 through the first threaded bar 8 on the inner wall. This drives the adjusting rod 4 to move back towards the limiting rod 3 along the slide groove of the connecting frame 2 until the anti-slip toothed plate 6 on the stop block 5 and the anti-slip toothed plate 6 on the limiting rod 3 clamp the workpiece together. After the workpiece is clamped, it can be processed simultaneously at each station by the machine tool; after processing, the rotating drum 7 is rotated in the opposite direction, the adjusting rod 4 is displaced in the opposite direction, the stop block 5 is separated from the limit rod 3, and the workpiece can be quickly removed.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
