Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a clamping device with chip removal and material ejection functions. Background Technology

[0002] A "fixture" is a tooling device used to fix, position, and support workpieces during machining, assembly, and inspection. It can simplify operations and improve machining accuracy and production efficiency. Fixtures are usually specially designed and manufactured according to the shape and machining requirements of specific workpieces; common types include machine tool fixtures, welding fixtures, and assembly fixtures. Using fixtures reduces reliance on operator skills and ensures consistent machining quality.

[0003] In existing technologies, the machining of parts often faces the problem of post-flushing, where iron filings generated during machining can easily enter the fixture, leading to fixture wear and reduced machining accuracy. Furthermore, for the first and second stage docking of heavy parts, existing technologies lack effective auxiliary devices, making the spindle docking process complex and time-consuming.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a clamp with chip removal and material ejection functions. Utility Model Content

[0005] The purpose of this invention is to provide a clamp with a chip removal and material ejection function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamping solution with chip removal and material ejection function includes a pull tube, a connecting plate at the tail end of the pull tube, a clamp mounted on the connecting plate, the clamp for fixing parts, a gripper mounted on the clamp, an outer cylinder sleeve inside the pull tube, an inner cylinder sleeve inside the outer cylinder sleeve, and a cylinder at the end of the inner cylinder sleeve.

[0008] As a preferred technical solution, the inner cylinder liner slides with the outer cylinder liner, and the outer cylinder liner is provided with a water spray hole.

[0009] As a preferred technical solution, the outer cylinder liner and water spray hole are used to handle the iron filings generated during the punching process.

[0010] As a preferred technical solution, the cylinder is used to control the air pressure within the inner cylinder liner, thereby assisting in docking and improving docking accuracy.

[0011] As a preferred technical solution, the gripper is adjustable to accommodate parts of different sizes.

[0012] As a preferred technical solution, the surface of the fixture is coated with an anti-rust coating to improve its corrosion resistance and extend its service life.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention relates to a fixture with a chip removal and ejection function. The combination of a pull tube and a cylinder effectively removes iron filings from the surface of parts during processing, preventing the filings from affecting the machining accuracy. Simultaneously, the inclusion of water spray holes allows for cooling and cleaning of the part surface, further improving machining quality.

[0015] The adjustable grippers on the fixture allow it to accommodate parts of different sizes and shapes, greatly improving its versatility and flexibility. The anti-rust coating on the fixture surface not only enhances its corrosion resistance but also reduces contamination of the parts' surfaces during machining, ensuring the quality of the parts' surfaces.

[0016] This invention offers significant advantages in improving machining accuracy, ensuring part surface quality, and extending fixture lifespan. Implementing this technical solution can effectively enhance production efficiency and product quality, demonstrating high practical value and promising market application prospects.

[0021] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a clamping solution with chip removal and material ejection function: it includes a pull tube 1, a connecting plate 2 is provided at the tail end of the pull tube 1, a clamp 3 is installed on the connecting plate 2, the clamp 3 is used to fix the parts, a gripper 4 is installed on the clamp 3, an outer cylinder sleeve 5 is provided inside the pull tube 1, an inner cylinder sleeve 7 is provided inside the outer cylinder sleeve 5, and a cylinder 8 is provided at the end of the inner cylinder sleeve 7.

[0023] The inner cylinder liner 7 and the outer cylinder liner 5 are connected by a sliding fit, allowing the inner cylinder liner 7 to slide freely within the outer cylinder liner 5. Furthermore, the outer cylinder liner 5 has multiple water spray holes 6 evenly distributed on it. These water spray holes 6 allow for water cooling of the part surface during machining, while simultaneously flushing away metal chips generated during machining, thereby reducing the impact of metal chips on machining accuracy.

[0024] The cylinder 8 controls the air pressure within the inner cylinder liner 7 to assist in the ejection and docking of parts. By precisely controlling the air pressure of the cylinder 8, the accuracy of part docking can be improved, especially in the first and second stage docking processes of heavy parts, where this function is particularly important.

[0025] The clamping jaws 4 are adjustable, allowing them to adapt to parts of different sizes and shapes by adjusting their opening and closing degree, thus improving the versatility and flexibility of the fixture 3. This adjustability enables the fixture 3 to be used in a variety of different machining applications, greatly expanding its range of applications.

[0026] The surface of fixture 3 is coated with an anti-rust coating, which not only improves the corrosion resistance of fixture 3, but also reduces contamination of the part surface during processing, ensuring the surface quality of the part. The use of the anti-rust coating allows fixture 3 to maintain good working condition even in harsh processing environments, extending its service life.

[0027] This invention effectively solves the problems existing in the prior art by combining a pull tube, a cylinder, a water spray hole, and adjustable grippers. This fixture not only improves machining accuracy and part surface quality, but also has high versatility and a long service life, demonstrating significant practical value and promising market application prospects.

[0028] In this embodiment, the part to be processed is placed on the fixture 3, and the opening and closing degree of the grippers 4 is adjusted to ensure that the part is firmly fixed on the fixture 3. Then, the cylinder 8 is activated, and the air pressure in the inner cylinder liner 7 is controlled to realize the ejection action of the part. During the processing, the water spray holes 6 on the outer cylinder liner 5 start spraying water to cool the surface of the part and flush away the generated iron filings, ensuring that the processing accuracy is not affected by the iron filings.

[0029] After processing is completed, cylinder 8 actuates again to eject the machined part for further processing or inspection. Because the gripper 4 is adjustable, when processing parts of different sizes and shapes, only the opening and closing degree of the gripper 4 needs to be adjusted, eliminating the need to change fixtures and greatly improving production efficiency.
