Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically to a clamping tool for copper-clad steel burr cutting tools. Background Technology

[0002] Copper-clad steel is widely used in power and communications fields, such as in grounding electrodes and cable shielding layers. During its processing, whether cutting or stamping, burrs are generated at the edges. Because copper-clad steel combines the relatively soft properties of the copper layer with the high strength of the steel core, ordinary deburring methods easily damage the material surface or fail to remove burrs completely. Specialized deburring tools require precise and stable clamping to ensure efficient and high-quality deburring operations.

[0003] For example, Chinese patent publication number CN218169433U discloses a cutting tool that is easy to clamp and position quickly. It includes a fixed sleeve, a guide rail fixed inside the fixed sleeve, a cutting tool body disposed inside the fixed sleeve, a sliding connection between the cutting tool body and the guide rail, a limit block fixed on the cutting tool body, and a fixing bolt on the outside of the fixed sleeve. The fixing bolt is threaded between the fixed sleeve and the cutting tool body. A connecting ring is sleeved on one end of the fixed sleeve, and the connecting ring is slidably sleeved on the outside of the limit block. This invention solves the problems of low efficiency and inconvenience in using existing cutting tools.

[0004] Currently, there are still some shortcomings in a cutting tool that is easy to clamp and position quickly. For example, the clamping process requires screwing in multiple sets of bolts in sequence, which is extremely time-consuming. The cumbersome bolt screwing steps slow down the overall clamping rhythm and affect the machining efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a clamping tool for copper-clad steel burr cutting tools, which solves the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A clamping tool for burring copper-clad steel cutting tools includes: a housing, a clamping cylinder provided on the bottom surface of the housing, a mounting frame provided inside the housing, the mounting frame being fixedly connected to the clamping cylinder, and a cutting tool being provided inside the clamping cylinder; and a clamping assembly provided inside the clamping cylinder for clamping the cutting tool.

[0008] Preferably, the clamping assembly includes: a connecting frame disposed inside the clamping cylinder, clamping rods hingedly mounted on both sides of the connecting frame, a hinged frame fixedly mounted on the inner top surface of the clamping cylinder, the hinged frame being hingedly connected to the clamping rods, a clamping block fixedly mounted on one side of the clamping rods, a cylinder fixedly mounted on the top surface of the mounting frame, a connecting hole being opened on the bottom surface of the mounting frame, and the shaft of the cylinder being fixedly connected to the connecting frame.

[0009] Preferably, the bottom surface of the box has a sliding opening, and an electric push rod is fixedly installed on one side of the inside of the box, with the shaft of the electric push rod fixedly connected to the mounting bracket.

[0010] Preferably, two guide holes are provided on both sides of the mounting bracket, and two guide rods are fixedly installed on one side of the inside of the housing, with the guide rods slidably sleeved together with the guide holes.

[0011] Preferably, an anti-slip pad is fixedly adhered to the inner circular wall surface of the clamping block.

[0012] Preferably, buffer pads are fixedly adhered to both sides of the inner side of the sliding opening.

[0013] In summary, the present invention has the following main advantages:

[0014] By setting up a connecting frame, when a cutting tool needs to be installed and clamped, the cylinder is activated, and the cylinder shaft begins to extend. The extension pushes the connecting frame downward. During the downward movement of the connecting frame, the clamping rods hinged on both sides move. Because the clamping rods are also hinged to the hinge frame on the top surface inside the clamping cylinder, this double-hinged structure makes the clamping rods move like levers. As the clamping blocks on both sides move inward, they gradually approach and tightly fit against the outer wall of the cutting tool. Finally, the friction and clamping force between the clamping blocks and the cutting tool are used to firmly fix the cutting tool inside the clamping cylinder. When the tool needs to be replaced, the cylinder is controlled to retract, and its shaft drives the connecting frame upward. The clamping rods move in the opposite direction under the action of the hinged structure, and the clamping blocks release their grip on the tool. The operator can then easily remove the old tool and install the new tool, greatly shortening the time required for tool clamping. The tool can be fixed and released in a short time, effectively improving the utilization rate of production equipment, reducing downtime caused by tool replacement, and improving processing efficiency.

[0015] By setting up an electric push rod and controlling its extension and retraction, the mounting frame drives the clamping cylinder and the internal cutting tool to achieve rapid and precise displacement, and makes lateral fine adjustments to the position of the cutting tool without disassembling the tool, thus achieving efficient processing of workpieces of various specifications.

[0021] 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.

[0022] refer to Figures 1-4 A clamping tool for cutting copper-clad steel burrs includes: a housing 1, a clamping cylinder 2 provided on the bottom surface of the housing 1, a mounting frame 8 provided inside the housing 1, the mounting frame 8 being fixedly connected to the clamping cylinder 2, and a cutting tool 3 being provided inside the clamping cylinder 2; and a clamping assembly provided inside the clamping cylinder 2 for clamping the cutting tool 3.

[0023] By setting up the clamping cylinder 2, the clamping cylinder 2 is not easily deformed when subjected to cutting force, ensuring that the cutting tool 3 is always in a precise and stable working position, which improves the accuracy of cutting and reduces defects caused by tool position deviation.

[0024] As a further embodiment of this utility model, the clamping assembly includes: a connecting frame 4, which is disposed inside the clamping cylinder 2. Clamping rods 5 are hingedly installed on both sides of the connecting frame 4. A hinge frame 6 is fixedly installed on the top surface inside the clamping cylinder 2. The hinge frame 6 is hingedly connected to the clamping rods 5. A clamping block 7 is fixedly installed on one side of the clamping rods 5. A cylinder 9 is fixedly installed on the top surface of the mounting frame 8. A connecting hole 10 is opened on the bottom surface of the mounting frame 8. The shaft of the cylinder 9 is fixedly connected to the connecting frame 4.

[0025] By setting the connecting frame 4, when it is necessary to install and clamp the cutting tool 3, the cylinder 9 is activated, and the shaft of the cylinder 9 begins to extend. The extension pushes the connecting frame 4 downward. During the downward movement of the connecting frame 4, it drives the clamping rods 5 hinged on both sides to move. Because the clamping rods 5 are also hinged to the hinge frame 6 on the top surface inside the clamping cylinder 2, this double hinge structure makes the clamping rods 5 move like a lever. As the clamping blocks 7 on both sides move inward, they gradually approach and tightly fit against the outer wall of the cutting tool 3. Finally, the clamping blocks 7 and the cutting tool are clamped together. The friction and clamping force between the clamping blocks 3 firmly fix the cutting tool 3 inside the clamping cylinder 2. When the tool needs to be replaced, the control cylinder 9 retracts, and its shaft drives the connecting frame 4 to move upward. The clamping rod 5 moves in the opposite direction under the action of the hinge structure, and the clamping block 7 releases its grip on the tool. The operator can then easily take out the old tool and install the new tool, which greatly shortens the time required for tool clamping. It can realize the fixing and loosening of the tool in a short time, effectively improve the utilization rate of production equipment, reduce downtime caused by tool replacement, and improve processing efficiency.

[0026] As a further embodiment of this utility model, a sliding opening 12 is provided on the bottom surface of the box 1, and an electric push rod 11 is fixedly installed on one side of the inside of the box 1. The shaft of the electric push rod 11 is fixedly connected to the mounting bracket 8.

[0027] By setting up an electric push rod 11 and controlling its extension and retraction, the mounting frame 8 drives the clamping cylinder 2 and the internal cutting tool 3 to achieve rapid and precise displacement, and makes lateral fine adjustments to the position of the cutting tool 3 without disassembling the tool, thus achieving efficient processing of workpieces of various specifications.

[0028] As a further embodiment of this utility model, two guide holes 13 are provided on both sides of the mounting bracket 8, and two guide rods 14 are fixedly installed on one side of the inside of the housing 1. The guide rods 14 are slidably sleeved together with the guide holes 13.

[0029] By setting the guide rod 14, when the electric push rod 11 drives the mounting frame 8 to move, the guide rod 14 ensures that the mounting frame 8 moves strictly in the predetermined direction, effectively avoiding instability such as displacement or shaking of the mounting frame 8 and the clamping cylinder 2 and cutting tool 3 it carries.

[0030] As a further embodiment of this utility model, an anti-slip pad 16 is fixedly adhered to the inner circular wall surface of the clamping block 7.

[0031] By setting the anti-slip pad 16, the tool will be subjected to large cutting force, vibration and possible impact during the cutting of copper-clad steel burrs. Ordinary clamping surfaces may slip. The anti-slip pad 16 fits tightly against the tool surface, so that it is firmly fixed in the clamping cylinder 2 under complex machining conditions, ensuring that the tool is always accurately positioned.

[0032] As a further embodiment of this utility model, buffer pads 15 are fixedly adhered to both sides of the inner side of the sliding opening 12.

[0033] By setting a buffer pad 15, when the mounting frame 8 is driven by the electric push rod 11 to reciprocate, due to vibration, inertia or occasional control errors during the processing, the mounting frame 8 and its connected parts may collide with the edge of the sliding port 12. The buffer pad 15 can effectively absorb the impact force generated by the collision, preventing the mounting frame 8, clamping cylinder 2 and other key components from being deformed, worn or even damaged due to hard impact, thereby extending the service life of the equipment and reducing the equipment maintenance cost.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
