Description

Technical Field

[0001] This utility model relates to the field of burr removal tools, and in particular to a burr removal device for treating the internal cross holes of a triangular valve body. Background Technology

[0002] In the field of mechanical manufacturing, especially in the production of precision fluid control components such as valves, burrs generated after machining are a significant factor affecting product quality and performance. Burrs not only affect the assembly accuracy of components and may lead to leaks, but they can also detach during long-term use, causing blockages or damage to other parts. Therefore, burr removal is an indispensable process in the manufacturing process.

[0003] For components with complex internal structures, such as valve bodies, especially those with intersecting holes, deburring presents significant challenges. Traditional manual deburring methods are inefficient and yield inconsistent quality, while existing automated or semi-automated deburring tools are typically designed for removing burrs from external surfaces or through-holes. When removing burrs from the intersecting holes inside a triangular valve body, the narrowness of the holes and the angle between the intersecting holes and the main channel make it difficult for general-purpose tools to access them. Even if access is possible, the cutting portion struggles to be effectively adjusted within the limited space to align and efficiently remove the burrs from the intersecting holes.

[0004] In existing technologies, tools for deburring inside workpieces often employ fixed cutter head structures or have cumbersome and complex cutter head rotation mechanisms, making it difficult to flexibly switch the cutter head's posture within the narrow internal space of a valve body. This limitation results in either incomplete removal of burrs from the intersecting holes inside a triangular valve body, leaving residual burrs, or the need for multiple complex operations, consuming significant time and labor costs, severely restricting production efficiency and product quality.

[0005] Therefore, this utility model proposes a burr removal device for treating the cross holes inside the valve body of a triangular valve to overcome the shortcomings of the prior art. Utility Model Content

[0020] 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.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides a burr removal device for treating the cross holes inside a triangular valve body, which aims to solve the problem that in the prior art, the tools are difficult to switch positions flexibly and perform effective cutting in a narrow internal space, resulting in low efficiency or incomplete removal of burrs from the cross holes.

[0022] The burr removal device for the internal cross hole treatment of the triangular valve body mainly consists of a workpiece 1 and a handle 4. The workpiece 1 is the object to be processed by the device, and the handle 4 is the main body for the operator to hold and operate. One end of the extension rod 5 is fixedly connected to the front end of the handle 4. The extension rod 5 is used to insert the working part of the device into the workpiece 1. The core working part of the device is the cutter 204, which is rotatably mounted on the other end of the extension rod 5. The cutter 204 is designed with a first insertion hole 206 and a second insertion hole 305. These insertion holes are crucial for the installation and movement of the cutter 204.

[0023] To enable the rotation of the tool 204, a positioning shaft 205 is fixedly mounted on the outer wall of the extension rod 5 and passes through the first insertion hole 206 of the tool 204. The positioning shaft 205 precisely forms the rotation axis of the tool 204, allowing the tool 204 to rotate around this axis. The device also includes a control mechanism 3 and a disassembly mechanism 2. The control mechanism 3 is located inside and outside the handle 4 and is connected to the second insertion hole 305 of the tool 204 through a complex transmission mechanism. The control mechanism 3 is specifically used to precisely control the tool 204 to switch between horizontal and vertical states to adapt to different operational needs. The disassembly mechanism 2 is located at the other end of the extension rod 5 and is connected to the positioning shaft 205 through the first insertion hole 206 of the tool 204. The disassembly mechanism 2 allows the tool 204 to be installed and disassembled conveniently and quickly, facilitating maintenance and replacement.

[0024] When the tool 204 needs to be inserted into the narrow passage inside the workpiece 1, the control mechanism 3 can adjust the tool 204 to a horizontal state so that the tool 204 can pass through smoothly; once the tool 204 reaches the cross hole area inside the workpiece 1 that needs to be processed, the control mechanism 3 can quickly switch it to a vertical state so that the cutting edge of the tool 204 is facing the burr to cut.

[0025] The disassembly mechanism 2 ensures that the tool 204 can be firmly and reliably fixed on the extension rod 5 throughout the entire operation, and can also be quickly disassembled when the tool 204 needs to be replaced. The positioning shaft 205 serves as the rotation center of the tool 204, ensuring the stability and accuracy of the tool 204 during state switching.

[0026] The control mechanism 3 is mainly composed of a button 301, a limit block 302, a spring 303, and an elastic connecting rod 304. The button 301 is located at one end of the handle 4 and is the interface for the operator to directly press to trigger the tool 204 to switch postures. The limit block 302 is provided inside the handle 4 and can slide along the inner wall of the handle 4. The button 301 is driven to the limit block 302 through the internal mechanical structure. This means that when the operator presses the button 301, the pressing force is directly transmitted to the limit block 302 through the internal structure, causing the limit block 302 to slide along its axis inside the handle 4.

[0027] A spring 303 is also provided inside the handle 4. One end of the spring 303 abuts against the inner side of the button 301, and the other end of the spring 303 abuts against the inner wall of the handle 4. When the spring 303 is in a compressed state, it provides a reset force for the button 301 and the limit block 302. When the pressing force is released, the spring force of the spring 303 pushes the button 301 and the limit block 302 back to the initial position.

[0028] One end of the elastic link 304 is fixedly connected to the outer wall of the limiting block 302, and the other end of the elastic link 304 is inserted into the second insertion hole 305 of the tool 204 and rotatably connected thereto. This connection method allows the linear sliding of the limiting block 302 to be converted into the pushing and pulling motion of the elastic link 304, which in turn drives the tool 204 to rotate around the positioning shaft 205 through the second insertion hole 305.

[0029] Specifically, when the operator presses button 301, the limit block 302 slides forward inside the handle 4, while compressing the spring 303. The sliding of the limit block 302 converts its axial movement into a torque on the tool 204 through the elastic link 304, so that the tool 204 can rotate from its initial vertical state to a horizontal state.

[0030] When the operator releases button 301, the reset force of spring 303 pushes button 301 and limit block 302 back to their original positions. The elastic link 304 then moves in the opposite direction, causing the tool 204 to return from a horizontal state to a vertical state. Through the precise linkage of control mechanism 3, the tool 204 can be conveniently and reliably switched between horizontal and vertical working postures, which greatly improves the adaptability and efficiency of the device in removing burrs from cross holes in narrow and complex spaces.

[0031] As a preferred embodiment of the disassembly mechanism 2, the other end of the extension rod 5 is rotatably connected to the mounting block 201, and the mounting block 201 is provided with a pull ring 202 on the outside; one end of the elastic locking rod 203 is connected to the pull ring 202, and the elastic locking rod 203 can be inserted and inserted through the interior of the mounting block 201, and can be elastically locked and fixed on the outer side wall of the extension rod 5. This combination of structures constitutes a complete and easy-to-operate disassembly mechanism 2. Furthermore, in order to achieve stable rotation of the mounting block 201, a pin is provided between the mounting block 201 and the other end of the extension rod 5. The mounting block 201 is rotatably connected to the other end of the extension rod 5 through this pin, providing the necessary operating space for installing or removing the tool 204. In addition, in order to clearly define the position of the pull ring 202, the pull ring 202 is located on the outside of the mounting block 201, and the pull ring 202 is connected to the end of the elastic locking rod 203 exposed outside the mounting block 201, which facilitates the operator to perform the pulling operation. More specifically, in order to achieve reliable locking, the path of the elastic locking rod 203 inside the mounting block 201 is precisely designed. The elastic locking rod 203 passes through the preset hole on the positioning shaft 205 along the inside of the mounting block 201. Finally, the elastic locking rod 203 is engaged and fixed in the corresponding engagement groove or hole at one end of the outer wall of the rod 5. This structure of engaging after passing through the positioning shaft 205 ensures that the tool 204 and the mounting block 201 will not loosen accidentally during operation. As a preferred embodiment of the control mechanism 3, in order to ensure the smooth sliding of the limit block 302 and limit its stroke, the limit block 302 is provided with a sliding guide structure that cooperates with the inner wall of the handle 4. The sliding guide structure not only guides the limit block 302 to make stable linear motion, but also limits the movement range of the button 301 at the starting and ending positions of the sliding guide structure, preventing excessive pressing from damaging the internal components. As a preferred embodiment of the movement mode of the tool 204, the tool 204 achieves posture switching through its rotational connection with the positioning shaft 205. This rotational connection limits the posture of the tool 204 to switch between horizontal and vertical states. This structural limitation is the physical basis for realizing the core function of the device and ensures the accuracy and repeatability of posture switching.

[0032] Working principle: The operator holds the handle 4 and inserts the extension rod 5 into the hole inside the workpiece 1 that needs to be deburred. At this time, in order to facilitate smooth entry into the narrow hole, the tool 204 is usually in a horizontally retracted state through the action of the control mechanism 3. The handle 4 serves as a platform for the operator to apply force and control the direction, and the extension rod 5 transmits the operator's control to the inside of the workpiece 1, while the workpiece 1 provides the external environment for the deburring operation. When the tool 204 reaches the cross-hole area inside the workpiece 1 and deburring is required, the operator presses the button 301 on the outside of the handle 4. The button 301 drives the limiting block 302 inside the handle 4 to slide forward through the internal mechanical structure. The limiting block 302 can slide along the inner wall of the handle 4, and its sliding stroke is limited by the sliding guide structure that cooperates with the inner wall of the handle 4. The sliding of the limiting block 302 transmits the thrust to the second insertion hole 305 of the tool 204 through the elastic connecting rod 304 fixedly connected to its outer wall. Since the tool 204 is rotatably mounted on the positioning shaft 205 at the end of the extension rod 5 through the first insertion hole 206, and the positioning shaft 205 forms the rotation axis of the tool 204, the thrust of the elastic connecting rod 304 causes the tool 204 to rotate around the positioning shaft 205, switching from the horizontal retracted state to the vertical unfolded working state. The rotation of the tool 204 is precisely limited by the positioning shaft 205, ensuring the stability and accuracy of the posture switching. Once the tool 204 is in the vertical working state, the operator can rotate the handle 4 to drive the extension rod 5 and the vertically positioned tool 204 to cut and remove the burrs in the cross holes inside the workpiece 1. When the deburring operation is completed or when it is necessary to remove the tool 204 from the workpiece 1, the operator releases the button 301. One end of the spring 303 inside the handle 4 abuts against the inner side of the button 301, and the other end abuts against the inner wall of the handle 4. The restoring force of the spring 303 pushes the button 301 and the limit block 302 back to the initial position. The elastic connecting rod 304 then moves in the opposite direction, causing the tool 204 to rotate back to the horizontal retracted state, making it easy to remove the workpiece 1. Furthermore, when the tool 204 is worn and needs to be replaced, the operator can use the disassembly mechanism 2 to pull the pull ring 202 located on the outside of the mounting block 201. The pull ring 202 is connected to one end of the elastic locking rod 203. Pulling the pull ring 202 will pull out the elastic locking rod 203, which is inserted through the inside of the mounting block 201, from the corresponding engaging groove or hole on the outer side wall of the extension rod 5. During the pulling process, the elastic locking rod 203 passes through the preset hole on the positioning shaft 205 along the inside of the mounting block 201. After the elastic locking rod 203 is disengaged, the mounting block 201, which is rotatably connected to the other end of the extension rod 5, can be rotated through the pin connected to the extension rod 5, thereby exposing the tool 204 and facilitating the replacement of the tool 204.

[0033] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
