Abstract
Description
Technical Field
[0001] This application relates to the field of machining technology, and in particular to a product fixing fixture. Background Technology
[0002] In modern industrial production, various tooling fixtures have become indispensable tools. These fixtures play a key role in assisting workpiece fixation, improving processing efficiency, and ensuring safe production. Especially in assembly line production and assembly operations, the convenience and stability of tooling fixtures directly affect production efficiency and product quality.
[0003] Currently, there are many types of tooling available on the market for fixing products. They usually have certain adjustment functions to adapt to the fixing needs of products of different specifications. However, most existing fixing tooling is a single-structure design with limited adjustment functions, making it difficult to adapt to the fixing requirements of products of various specifications. Some tooling requires frequent replacement of parts during operation, which increases the complexity of operation and affects work efficiency. For products of specific shapes, especially round products with flanges, existing tooling is prone to rotational displacement during fixing, affecting processing accuracy and safety.
[0004] Therefore, we need a product fixing fixture to solve the problem that the fixing fixture is prone to rotational displacement when fixing products with flanges, which affects the processing. It can prevent the fixing fixture from rotating and shifting when fixing products with flanges, thus avoiding affecting the processing. Utility Model Content

After the product is placed on it, the first and second clamping plates are pressed against the bolt holes on the product by the rotating eccentric device, and the fixing part is further fixed in the threaded hole of the product. After pressing, it can be axially fixed and prevent the product from rotating. This solves the problem that the fixing fixture is prone to rotational displacement when fixing products with flanges, which affects the processing. It can prevent the fixing fixture from rotating and shifting when fixing products with flanges, thus preventing the processing from being affected.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0035] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and apparatus have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.
[0036] Example 1: As Figure 1-3 As shown, a product fixing fixture includes:
[0037] Base 1; support base 2, the support base 2 is set at the center of base 1; fixed bracket 3, the fixed bracket 3 is fixed to the upper end of base 1;
[0038] Adjustable bracket 4 is set on the upper end of support base 2. Fixed bracket 3 and adjustable bracket 4 are symmetrically set on the left and right ends of support base 2. Through the symmetrical arrangement of base 1, support base 2, fixed bracket 3 and adjustable bracket 4, the product fixing fixture can balance the clamping force and achieve symmetrical fixing. It can maintain the fixture and stably clamp workpieces 8 of different sizes, avoiding slippage or displacement caused by imbalance.
[0039] The first clamping plate 51 is disposed above the fixed bracket 3. The front end of the first clamping plate 51 is provided with a fixing part 54, which is connected to the workpiece 8. The fixing part 54 is configured as a threaded column.
[0040] The second clamping plate 52 is located above the adjustable bracket 4. The second clamping plate 52 has the same shape as the first clamping plate 51. The second clamping plate 52 is also provided with a fixing part 54, which is connected to the workpiece 8. The fixing part 54 is a threaded column.
[0041] Adjusting bolt 6 connects the first clamping plate 51 and the fixed bracket 3, and the second clamping plate 52 and the adjustable bracket 4. Adjusting bolt 6 is equipped with a limit locking device.
[0042] An eccentric device 7 is respectively disposed on the upper ends of the first clamping plate 51 and the second clamping plate 52. The upper ends of the first clamping plate 51 and the second clamping plate 52 are provided with guide grooves 53. The eccentric device 7 is connected to the guide grooves 53. The eccentric device 7 includes: an eccentric wheel 71, which is disposed in the guide groove 53; and an adjusting handle 72, which is connected to the eccentric wheel 71. The eccentric wheel 71 is used to press the first clamping plate 51 and the second clamping plate 52 downward.
[0043] The fixed bracket 3 and the adjustable bracket 4 are connected to the base 1 by bolts.
[0044] The front ends of the first clamping plate 51 and the second clamping plate 52 are both chamfered. The chamfering of the front ends of the first clamping plate 51 and the second clamping plate 52 can reduce the wear on the edge of the workpiece 8 during clamping, prevent scratches or dents from being generated during clamping, and ensure the surface quality of the workpiece 8.
[0045] The upper surface of the support base 2 is parallel to the lower surface of the first clamping plate 51 and the second clamping plate 52. The upper surface of the support base 2 is parallel to the lower surface of the first clamping plate 51 and the second clamping plate 52, ensuring that the contact surface between the clamping plate and the workpiece 8 is flat, avoiding the workpiece 8 from being skewed or tilted during the fixing process, and further improving the stability and accuracy of the tooling clamping.
[0046] The vertical distance between the first clamping plate 51 and the second clamping plate 52 is adjusted by adjusting bolt 6, and the required horizontal distance is adjusted by adjusting bracket 4. After the product is placed on it, the first clamping plate 51 and the second clamping plate 52 are pressed against the bolt holes on the product by rotating eccentric device 7. The fixing part 54 is further fixed in the threaded hole of the product. After pressing, it can be axially fixed and prevent the product from rotating. This solves the problem that the fixed tooling is prone to rotational displacement when fixing products with flanges, which affects the processing. It can prevent the fixed tooling from rotating and shifting when fixing products with flanges, thus preventing the processing from being affected.
[0047] Example 2: Figure 4-5 As shown, based on Embodiment 1, this embodiment further improves the first clamping plate 51 and the second clamping plate 52, including:
[0048] A threaded hole and a through hole are provided on the upper end of the first clamping plate 51 and the second clamping plate 52. The threaded hole and the through hole are coaxially arranged. The threaded hole is located on the upper end of the through hole, and the diameter of the threaded hole is larger than the size of the through hole.
[0049] The fixing part 54 is configured as a threaded post with different diameters in the upper and lower parts. The upper part of the fixing part 54 is connected to the threaded holes of the first clamping plate 51 and the second clamping plate 52. The lower part of the fixing part 54 is connected to the threaded hole on the workpiece 8 through the through holes of the first clamping plate 51 and the second clamping plate 52.
[0050] This allows the fixing part 54 to be securely connected to the workpiece 8 with a threaded hole, improving the versatility of the tooling. When in use, simply unscrew the fixing part 54 and replace it with a fixing part 54 of different specifications as needed, making it suitable for workpieces 8 of different shapes and sizes, especially circular workpieces 8 with threaded holes, thus enhancing the reliability of clamping.
[0051] Example 3: Figure 1-5 As shown, based on Examples 1-3, this example also provides a method for using a product fixing fixture, including:
[0052] Use bolts to install the fixed bracket 3 and the adjustable bracket 4 to the corresponding positions on the base 1.
[0053] Rotate the adjusting bolt 6 to adjust the clamping distance between the fixed bracket 3 and the adjustable bracket 4 to accommodate the width of the workpiece 8.
[0054] Place workpiece 8 on support base 2 and align the center of workpiece 8 with support base 2.
[0055] Depending on the length or shape of the workpiece 8, the positions of the first clamping plate 51 and the second clamping plate 52 are adjusted so that the position of the fixing part 54 at the front end corresponds to the position of the connecting hole on the workpiece 8.
[0056] Adjust the position of the eccentric wheel 71 so that it fits tightly against the surface of the clamping plate through the guide groove 53.
[0057] Rotate the eccentric wheel 71 using the adjusting handle 72, and press the first clamping plate 51 and the second clamping plate 52 downwards by eccentric force to ensure that the workpiece 8 is firmly fixed and to prevent loosening or displacement.
[0058] Use the limiting locking device of adjusting bolt 6 to lock the adjusted position of the clamping plate to prevent the clamping plate from loosening during operation.
[0059] After confirming that workpiece 8 is securely fixed, perform the necessary processing operations to ensure that workpiece 8 does not slide or rotate during the processing.
[0060] After the processing is completed, first rotate the adjusting handle 72 to loosen the eccentric wheel 71, gradually release the pressure of the clamping plate on the workpiece 8, and unscrew the fixing part 54.
[0061] Rotate the adjusting bolt 6 to increase the spacing between the clamping plates, making it easier to remove the workpiece 8.
[0062] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
