Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and more specifically, to a tooling and fixture for attitude correction. Background Technology

[0002] In machining, it is often necessary to cut beveled surfaces on parts to meet the processing requirements of the components in actual operation. Since the cutting tools used to cut parts usually move in a vertical direction, they cannot directly cut the parts into bevels. Therefore, factories often design an inclined support platform to place the parts and fix them on the inclined platform with appropriate fixing devices, so that the cutting tool can easily cut the beveled surface of the part.

[0003] However, in actual operation, different parts often require support surfaces with different inclinations to correct the part's posture so that the cutting tool can cut the part into a bevel with a preset inclination. Existing fixtures only have one inclined support surface, forcing factories to replace them with another batch of fixtures with support surfaces of the corresponding inclination to accommodate the cutting tool's bevel cutting operation, resulting in poor versatility. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model first provides a tooling fixture for attitude correction, comprising: a support block for machining a sloping structure on a part; the part having a protrusion at its bottom; the part having at least one through hole on its top surface; the tooling fixture further comprising: a base connected and fixed to a machine tool; at least one pair of clamping blocks movably disposed on the base; the clamping blocks abutting against the periphery of the support block to restrict the displacement of the support block; the support block having a first sloping surface; the first sloping surface having: a positioning groove adapted to the shape of the protrusion for positioning the part; a limiting groove corresponding to the position of the through hole, wherein a positioning post is slidably fitted within the limiting groove; the positioning post passing through the through hole and extending into the limiting groove to fix the part and the support block; the support block having a second sloping surface.

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0027] This utility model provides a tooling fixture for posture correction, including: a support block 1, which is used to form a sloping structure 7 on a part 2; the bottom of the part 2 has a protrusion 201; the protrusion 201 is generally tubular or columnar, or other irregular shape, and this utility model takes a tubular protrusion 201 as an example; the top surface of the part 2 has at least one through hole 202, and the attached figure shows two through holes 202 as an example; the tooling fixture also includes: a base 3, which is connected and fixed to a machine tool; At least one pair of clamping blocks 4 are movably mounted on the base 3; the clamping blocks 4 abut against the periphery of the support block 1 to limit the displacement of the support block 1; the support block 1 has a first inclined surface 101; the first inclined surface 101 is provided with: a positioning groove 102 adapted to the shape of the protrusion 201 for positioning the part 2; a limiting groove 103 corresponding to the position of the through hole 202, and a positioning post 104 is slidably fitted in the limiting groove 103; the positioning post 104 passes through the through hole 202 and extends into the limiting groove 103 to fix the part 2 and the support block. 1; The support block 1 has a second inclined surface 105; the second inclined surface 105 has a different degree of inclination than the first inclined surface 101, so as to adapt to the processing requirements of parts 2 with different inclination postures; different parts 2 often need to be cut into inclined surface structures 7 with different inclination angles. Traditional tooling fixtures often only have one inclined surface structure 7, which makes the tooling fixture less versatile. In this application, two inclined surfaces are provided, which can adapt to the processing requirements of parts 2 with two different inclination postures, that is, the inclined surface structure 7 meets the requirements of two inclination angles.

[0028] like Figure 5-6 As shown, the second inclined surface 105 is provided with: a positioning groove 106 for cooperating with the protrusion 201 of the part 2 that requires another tilting posture; and a limiting groove 107 that corresponds to the through hole 202 of the part 2 that requires another tilting posture.

[0029] like Figure 1-2 As shown, the base 3 has multiple inverted T-shaped grooves 301 on its circumference; the clamping block 4 has an inverted T-shaped boss 401 at its bottom for sliding engagement with the inverted T-shaped grooves 301. The tooling fixture also includes: a drive assembly, which is a cylinder or a hydraulic cylinder; the cylinder or hydraulic cylinder has a telescopic end, which is a piston rod; the telescopic end abuts against the clamping block 4; in specific operation, taking the cylinder as an example, the operation is as follows: when clamping the support block 1: the cylinder is inflated, then the piston rod is pushed out, and then the clamping block 4 is pushed to press the support block 1; when releasing the support block 1: the cylinder is deflated, then the spring is reset, and then the clamping block 4 is retracted.

[0030] In one embodiment, such as Figure 5-6 As shown, the first inclined surface 101 is provided with a relief groove 108. A cutting tool for vertical cutting is generally provided above the part 2. The cutting tool falls vertically to process the inclined surface structure 7 on the part 2. The relief groove 108 can prevent the cutting tool from damaging the surface of the support block 1.

[0031] In one embodiment, such as Figure 1 As shown, the clamping block 4 and the support block 1 are abutted by a limiting plate 5 to prevent the clamping block 4 from directly abutting the support block 1. Because the force-bearing surface at the end of the clamping block 4 is small, it is easy to cause local damage to the support block 1 when under force. The limiting plate 5 is generally made of steel or similar metal. Here, the limiting plate 5 has the function of dispersing the force on the support block 1. The limiting plate 5 cooperates with the periphery of the support block 1.

[0032] In one embodiment, such as Figure 1 As shown, the tooling fixture also includes: a limiting component, which comprises multiple stacked limiting circular plates 6, with the diameter of the limiting circular plates 6 decreasing towards the top. Two limiting circular plates 6 are provided here. Each limiting circular plate 6 abuts against two adjacent limiting plates 5, specifically forming a corner between the two adjacent limiting plates 5. The limiting circular plate 6 is positioned at this corner, thus limiting the ends of the two adjacent limiting plates 5 and preventing them from dislodging. A connecting rod 601 passes through the limiting circular plate 6. A slide 602 is fixed to the bottom of the connecting rod 601, and the slide 602 slides against the inner wall of the inverted T-groove 301, allowing the position of the limiting circular plate 6 to be adjusted. The slide 602 is fixed to the base 3, specifically by using the inverted T-shaped protrusion 401 of the clamping block 4 and the inverted T-groove 301. Threaded holes are also provided on the inner walls of the slide 602 and the inverted T-groove 301, and bolts are fitted into the inner walls of the threaded holes, thereby securing the base 3. Of course, in another embodiment, especially when mass-producing inclined structure 7 on part 2, the fixing method of the limiting circular plate 6 can be a cylinder or a hydraulic cylinder; the cylinder or hydraulic cylinder has a telescopic end, i.e., a piston rod; the telescopic end directly abuts against the slide table 602, or a mounting plate is fixed on the piston rod, and the mounting plate abuts against the slide table 602. Taking the cylinder as an example, its specific operation is as follows: when clamping the support block 1: the cylinder is inflated, then the piston rod is pushed out, and then the limiting circular plate 6 is pushed to press the limiting plate 5, thereby pressing the support block 1; when releasing the support block 1: the cylinder is deflated, then the spring is reset, and then the limiting circular plate 6 is retracted, thereby releasing the support block 1.

[0033] In one embodiment, such as Figure 1-2 As shown, the tooling fixture includes: a connector, which replaces the drive assembly in the above embodiment; the connector includes a bolt 402; an inverted T-slot 301 and an inverted T-bore 401 are respectively provided with threaded holes; the inner wall of the threaded hole is connected to the bolt 402, thereby fixing the clamping block 4 on the base 3.

[0034] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
