Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting, in particular to a waterproof structure of a turning wire cutting guide wheel. Background Art

[0002] Wire cutting is an electrospark machining method widely used in precision machining of metal materials. In a wire cutting machine, the guide wheel plays a very important role. The guide wheel is used to guide and support the electrode wire (usually a thin metal wire) to move along a preset path on the workpiece. It ensures the stability and accuracy of the electrode wire during machining, avoids deviation or bending of the electrode wire, and ensures machining quality.

[0003] During the installation process, there will be a gap at the connection between the guide wheel and the wire cutting machine. If the external liquid passes through the connection between the guide wheel and the wire cutting and enters the interior of the guide wheel, it will cause rust on the internal structure of the guide wheel (bearing corrosion), directly affecting the rotation accuracy of the guide wheel, and thus affecting the accuracy of the entire processing process.

[0004] Secondly, some guide wheels are equipped with electronic components such as sensors to detect parameters such as the tension and speed of the electrode wire. Once external liquid enters the guide wheel, the internal electronic components will be damaged, causing equipment failure and affecting processing efficiency.

[0005] For the guide wheel at the corner of wire cutting (refer to the attached Figure 3 The existing steering guide wheel assembly for wire cutting is only 60MM or 70MM in length, and the guide wheel diameter is more than 20MM. Due to the influence of the length, the horizontal movement range will be limited during the turning wire cutting process, thereby limiting the range of wire cutting; due to the large diameter of the guide wheel, it will not be able to pass through a narrow position, thereby limiting the scope of processing.

[0047] Please refer to Figure 1-Figure 2 An embodiment of the utility model provides a waterproof structure of a turning line cutting guide wheel. The waterproof structure of the turning line cutting guide wheel in this embodiment includes:

[0048] The mounting member 110 is provided on the wire cutting machine, and the mounting member 110 is provided with a mounting hole 110a along the axial direction;

[0049] A guide wheel member 120, the end of which is disposed in the mounting hole 110a, and the guide wheel member 120 is provided with a convex positioning portion 121, and the positioning portion 121 is located outside the mounting hole 110a;

[0050] A waterproof component is sleeved on the guide wheel component 120, and the waterproof component is located between the mounting component 110 and the positioning portion 121. One end of the waterproof component abuts against the positioning portion 121, and the other end of the waterproof component abuts against the mounting component 110. The waterproof component completely blocks the mounting hole 110a along the axial direction of the mounting component 110.

[0051] In this embodiment, the installation member 110, the guide wheel member 120 and the waterproof component are used together to form a waterproof closed loop structure. When the guide wheel member 120 is installed on the installation member 110 through the installation hole 110a, the waterproof component is placed in the gap between the guide wheel member 120 and the installation member 110. The two ends of the waterproof component are in close contact with the positioning portion 121 and the installation member 110, respectively, to form a sealed barrier, thereby preventing moisture from entering the guide wheel through this connection point.

[0052] By effectively preventing moisture from entering, the internal structure and electronic components of the guide wheel are protected, reducing failures caused by internal corrosion or component damage, thereby improving the accuracy of the entire wire cutting process and the reliability of the equipment.

[0053] Reduces the need for maintenance due to water erosion, extends the service life of the guide wheel and wire cutter, and reduces long-term operating costs.

[0054] By keeping the guide wheel components dry, it helps maintain the stability of the entire processing environment and avoids processing errors caused by environmental changes.

[0055] The mounting member 110 is generally annular and cylindrical in shape, and has a mounting hole 110 a opened along the axis of the machine. The mounting hole 110 a is used to accommodate the end of the guide wheel member 120 .

[0056] The mounting member 110 not only serves as a supporting structure for the guide wheel member 120 , but also ensures that the guide wheel member 120 can be stably installed at a necessary position.

[0057] The end of the guide wheel 120 is installed in the mounting hole 110a, and a positioning portion 121 is protruded from the outside. The positioning portion 121 protrudes outside the mounting hole 110a, and plays a role in positioning and stabilizing the guide wheel 120. The guide wheel 120 is a circular shaft. The guide wheel 120 is a key component for realizing wire cutting, and its accurate position and stability directly affect the accuracy of the cutting process.

[0058] The waterproof component is sleeved on the guide wheel member 120 and is located between the mounting member 110 and the positioning portion 121. One end of the waterproof component abuts against the positioning portion 121, and the other end abuts against the mounting member 110, completely covering the mounting hole 110a.

[0059] Prevent moisture from entering the interior of the guide wheel, thereby protecting the mechanical and electronic components inside the guide wheel member 120 from water damage.

[0060] In at least one embodiment of the present application, the waterproof component includes:

[0061] The waterproof cover 130 includes a fixing portion 131 and an annular shielding portion 132. The fixing portion 131 is sleeved on the guide wheel component 120. A waterproof cavity 130a is enclosed between the fixing portion 131, the shielding portion 132 and the mounting component 110. The mounting component 110 is located in the waterproof cavity 130a so that the waterproof cover 130 shields the connection between the guide wheel component 120 and the mounting component 110.

[0062] Please refer to Figure 1-Figure 2 In this embodiment, when the waterproof cover 130 is installed between the guide wheel member 120 and the mounting member 110, the fixing portion 131 is tightly mounted on the guide wheel member 120, and the annular shielding portion 132 covers the outside of the fixing portion 131 and forms a waterproof cavity 130a between the fixing portion 131 and the mounting member 110.

[0063] Ensure that any liquid (such as coolant used during the cutting process) cannot penetrate into the interior of the guide wheel or affect the direct connection between the guide wheel and the mounting member 110.

[0064] By effectively isolating moisture, the reliability of the guide wheels inside the wire cutting machine is improved and the maintenance requirements caused by water damage are reduced.

[0065] Since the internal structure and electronic components of the guide wheel member 120 are well protected, the reduction in precision due to corrosion or damage is avoided, thereby maintaining high precision and stability of the processing process.

[0066] The waterproof cover 130 prolongs the service life of the guide wheel component 120 and reduces the wear and corrosion of the guide wheel component 120 caused by environmental factors (such as water, coolant, etc.).

[0067] The fixing portion 131 is used to be sleeved on the guide wheel member 120 , and is the basic portion for connecting the waterproof cover 130 and the guide wheel member 120 , and is a ring-shaped structure.

[0068] The annular shielding portion 132 is connected to the fixing portion 131 and forms a waterproof cavity 130a with the mounting member 110. The function of the annular shielding portion 132 is to isolate the connection between the guide wheel member 120 and the mounting member 110 in space, and prevent liquid from directly passing through the connection between the guide wheel member 120 and the mounting member 110. The annular shielding portion 132 is an annular structure.

[0069] The fixing portion 131 and the annular shielding portion 132 together enclose a waterproof cavity 130a, and the mounting member 110 is located in the waterproof cavity 130a. The waterproof cavity 130a is specifically used to isolate liquid and prevent it from entering the connection between the guide wheel and the mounting member 110.

[0070] In at least one embodiment of the present application, the shielding portion 132 is provided with an annular abutting protrusion 1321 protruding from one side of the shielding portion 132 close to the mounting member 110;

[0071] The mounting member 110 is provided with a mounting portion 111 protruding toward one side close to the waterproof cover 130 , and the annular abutting protrusion 1321 abuts against the mounting portion 111 along a first direction A, and the first direction A is perpendicular to the axial direction of the mounting member 110 .

[0072] Please refer to Figure 1-Figure 2 In this embodiment, the annular abutting protrusion 1321 is arranged on the shielding portion 132 of the waterproof cover 130, close to the side of the mounting member 110. The annular abutting protrusion 1321 forms a close contact with the corresponding part of the mounting member 110, thereby achieving a better sealing effect and preventing moisture from penetrating.

[0073] The mounting portion 111 of the mounting member 110 protruding from one side of the waterproof cover 130 is used to tightly abut against the annular abutting protrusion 1321 .

[0074] The presence of the mounting portion 111 enhances the stability of the overall structure and serves as a sealing point between the waterproof cover 130 and the mounting member 110 to effectively prevent moisture from entering.

[0075] The annular contact protrusion 1321 contacts the mounting portion along a direction (first direction A) perpendicular to the axial direction of the mounting member 110 .

[0076] It ensures the uniformity and stability of the sealing effect and is also easy to install and maintain.

[0077] When the waterproof cover 130 is mounted on the guide wheel member 120, its annular abutting protrusion 1321 forms a close contact with the mounting portion on the mounting member 110. This not only improves the waterproof performance, but also ensures the position stability of the waterproof cover 130 during installation and use. The close abutment reduces the chance of moisture and other contaminants entering, and effectively protects the guide wheel member 120 and the electronic components inside it.

[0078] The close contact between the annular abutting protrusion 1321 and the mounting portion significantly improves the sealing performance of the waterproof cover 130, effectively preventing moisture from entering the guide wheel and reducing the risk of damage to the guide wheel and internal components of the wire cutting machine.

[0079] Not only the waterproof performance is improved, but also the stability of the overall structure is increased, ensuring that the waterproof cover 130 is not easy to loosen or fall off during long-term use.

[0080] In at least one embodiment of the present application, the waterproof cavity 130 a is formed between the annular abutting protrusion 1321 and the fixing portion 131 , and the mounting portion is partially received in the waterproof cavity 130 a .

[0081] Please refer to Figure 1-Figure 2In this embodiment, when the waterproof cover 130 is installed, the annular contact convex portion 1321 and the fixing portion 131 are jointly formed into a waterproof cavity 130a, and the mounting portion partially enters the waterproof cavity 130a. The waterproof cavity 130a effectively blocks the potential moisture penetration path between the guide wheel and the mounting member 110, thereby improving the overall waterproof protection effect of the guide wheel. At the same time, because the mounting portion is partially accommodated in the waterproof cavity 130a, an additional sealing layer is added, thereby further improving the waterproof performance.

[0082] Through the precisely designed waterproof cavity 130a and the close combination of the mounting portion and the waterproof cavity 130a, the waterproof performance of the overall structure is greatly improved, and the intrusion of moisture and pollutants is effectively prevented.

[0083] The failure of the guide wheel and internal parts of the wire cutting machine due to water damage is reduced, thereby improving the stability and reliability of the equipment.

[0084] In at least one embodiment of the present application, the geometric center of the guide wheel member 120 has a center position 120a, one end of the annular shielding portion 132 is fixed to the fixed portion 131, and the other end of the annular shielding portion 132 is inclined from the connection with the fixed portion 131 in a direction away from the center position 120a.

[0085] In at least one embodiment of the present application, the diameter of the annular shielding portion 132 close to the fixing portion 131 is recorded as a, and the diameter of the annular shielding portion 132 away from the fixing portion 131 is recorded as b, satisfying the relationship: a<b.

[0086] Please refer to Figure 1-Figure 2 In this embodiment, when the annular shielding portion 132 is mounted on the guide wheel 120, it ensures that the portion extending outward from the fixing portion 131 has an outwardly inclined shape, which not only enhances the overall strength of the structure, but also provides a natural flow direction for moisture through its specific geometric shape, that is, flowing outward from the center position 120a. The accumulation of moisture on the surface of the guide wheel 120 is effectively reduced, especially at the key connection position.

[0087] By guiding the moisture away from the center position 120a of the guide wheel member 120 and other important components, potential damage to the device caused by moisture is reduced, and the waterproof performance and reliability of the device are improved.

[0088] Since moisture and contaminants can more easily flow away from the guide wheel surface, daily maintenance of the equipment becomes simpler and more efficient, reducing maintenance costs and time.

[0089] One end of the annular shielding portion 132 is fixed to the fixing portion 131 , and is formed to be inclined from the connection point of the fixing portion 131 toward a direction away from the center position 120 a .

[0090] The annular shielding portion 132 not only provides waterproof protection for the contact point, but also reduces the possibility of moisture erosion.

[0091] In at least one embodiment of the present application, the waterproof component includes:

[0092] The sealing ring 140 is disposed between the fixing portion 131 and the positioning portion 121 , and two sides of the sealing ring 140 are respectively in contact with the fixing portion 131 and the positioning portion 121 .

[0093] Please refer to Figure 1-Figure 2 In this embodiment, the sealing ring 140 is installed between the fixing portion 131 and the positioning portion 121, blocking moisture and pollutants that may damage the internal structure of the guide wheel 120; secondly, it also maintains the stability of the internal environment of the guide wheel 120, ensuring the accuracy and consistency of the wire cutting process. The presence of the sealing ring 140 significantly improves the performance of the entire waterproof structure.

[0094] By effectively sealing the key joint, the sealing ring 140 significantly improves the waterproof performance of the guide wheel member 120 and reduces the risk of moisture intrusion.

[0095] The sealing ring 140 protects the internal structure of the guide wheel from being damaged, thereby improving the reliability and service life of the entire wire cutting equipment.

[0096] Two sides of the sealing ring 140 are in close contact with the fixing portion 131 and the positioning portion 121 respectively.

[0097] It ensures that the sealing ring 140 can effectively seal the gap between the fixing portion 131 and the positioning portion 121, prevent moisture and pollutants from penetrating and entering, and protect the inside of the guide wheel from damage.

[0098] In at least one embodiment of the present application, the length of the guide wheel member 120 is denoted as c, which satisfies the relationship: 90 mm ≤ c ≤ 120 mm.

[0099] Please refer to Figure 1-Figure 2 In this embodiment, the length of the guide wheel member 120 is denoted as c, which satisfies the relationship: 90mm≤c≤120mm. Within this length range, the guide wheel member 120 can not only adapt to the processing requirements of workpieces of different sizes, but also ensure that the processing coordinates of the workpiece can be effectively obtained in a narrow steering processing space.

[0100] The guide wheel member 120 can maintain sufficient stability during the processing, while providing a sufficient range to adapt to different processing conditions, thereby improving the processing accuracy.

[0101] In at least one embodiment of the present application, the maximum diameter of the center position 120a is denoted as d, which satisfies the relationship: 9mm≤d≤19mm.

[0102] Please refer to Figure 1-Figure 2 In this embodiment, the maximum diameter of the center position 120a is denoted as d, which satisfies the relationship: 9mm≤d≤19mm. This ensures that the guide wheel 120 can perform efficient and accurate wire cutting in a narrow space.

[0103] Allows the wire EDM to adjust its path more flexibly when processing complex shapes or small parts or narrow turning ranges, especially when performing turning operations.

[0104] By allowing machining in tighter spaces, this design reduces restrictions on workpiece size and shape, providing users with greater design freedom and machining flexibility.

[0105] In at least one embodiment of the present application, the end of the guide wheel member 120 is provided with a threaded portion 122;

[0106] The threaded portion 122 is fixedly connected to the positioning portion 121, and the positioning portion 121 and the threaded portion 122 are coaxially arranged;

[0107] The waterproof structure of the turning wire cutting guide wheel also includes:

[0108] A first nut 150 is disposed at one end of the threaded portion 122 away from the positioning portion 121 and is threadedly connected to the threaded portion 122;

[0109] A second nut 151 is disposed between the first nut 150 and the positioning portion 121 and is threadedly connected to the threaded portion 122;

[0110] Among them, the first nut 150 is adjusted so that the positioning portion 121 makes the waterproof cover 130 abut against or not abut against the mounting member 110; the second nut 151 and the first nut 150 are adjusted so that the first nut 150 and the second nut 151 abut against the two sides of the mounting portion respectively, so as to fix the end of the guide wheel member 120 on the mounting member 110.

[0111] Please refer to Figure 1-Figure 2In this embodiment, when installing the guide wheel member 120, the contact pressure between the guide wheel member 120 and the mounting member 110 and the fixed position of the guide wheel member 120 on the mounting member 110 are adjusted by tightening or loosening the first nut 150 and the second nut 151. The operator is allowed to adjust the degree of compression of the waterproof cover 130 as needed, ensuring a good seal between the waterproof cover 130 and the mounting member 110, and also allowing the installation position of the guide wheel member 120 to be fine-tuned according to processing requirements, thereby improving the flexibility of installation and the adaptability of the equipment.

[0112] By precisely adjusting the contact pressure between the guide wheel component 120 and the waterproof cover 130, the sealing performance of the guide wheel waterproof structure is improved, effectively preventing moisture and pollutants from entering the interior of the guide wheel.

[0113] The threaded connection and double nut adjustment mechanism ensure the stability and accuracy of the guide wheel member 120 during installation, which helps to maintain high accuracy of the wire cutting process.

[0114] A threaded portion 122 is disposed at the end of the guide wheel member 120 . The threaded portion 122 is fixedly connected to the positioning portion 121 and is coaxially arranged with the positioning portion 121 .

[0115] The stability and accuracy of the guide wheel member 120 during installation are ensured, and the threaded connection provides a reliable fixing method to ensure accurate alignment between the guide wheel member 120 and the fuselage.

[0116] The first nut 150 is located at one end of the threaded portion 122 away from the positioning portion 121 and is connected to the threaded portion 122. The second nut 151 is disposed between the first nut 150 and the positioning portion 121 and is also threadedly connected to the threaded portion 122.

[0117] By adjusting the two nuts, the position of the guide wheel member 120 and the sealing effect of the waterproof cover 130 can be accurately controlled, so as to achieve close contact or separation between the guide wheel member 120 and the mounting member 110, and fix the end of the guide wheel member 120 on the mounting member 110.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
