Description

Technical Field

[0001] The present application relates to the field of tooling, and in particular to a tooling assembly for an elastic component and an elastic component. Background Art

[0002] In a measurement-while-drilling pulser instrument, an execution unit that moves linearly up and down inside the measurement-while-drilling pulser instrument is generally provided with a compression spring as an energy buffer. Since the selected spring wire diameter is relatively thick and hard, a force of about 300 N needs to be overcome for installation during normal installation.

[0003] In addition, the part dimensions that cooperate with the spring have relatively high precision, and the spatial structure is relatively compact. During the installation process of the spring, it is necessary to avoid rubbing against other parts, which makes the installation difficult, and existing installation tools are difficult to meet its installation requirements.

[0006] A tooling component for an elastic component according to an embodiment of the present application.

The driving member has a locking installation cavity for installing a locking ring. The locking installation cavity communicates with the end of the driving member and has an installation opening. Since the spring is restricted within a specific structural range of the tooling component, that is, the expansion and contraction of the spring and related operations are carried out in a closed or semi-closed environment composed of the seat body, the housing, the driving member, etc., the spring will not come into contact with other parts randomly in the pre-compressed state. Compared with the traditional installation method, it avoids problems such as installation difficulties and part damage that may be caused by the rubbing of the spring against other parts, thereby making the spring installation more convenient and efficient, and improving the reliability and safety of the installation.

[0031] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0032] A tooling component 100 for an elastic component 101 according to an embodiment of the present application. The elastic component 101 includes a seat body 3. An accommodating cavity 31 adapted to accommodate a spring 4 is formed in the seat body 3. The spring 4 is telescopically disposed in the accommodating cavity 31. A telescopic shaft 5 that abuts against the end of the spring 4 is disposed in the accommodating cavity 31. The tooling component 100 includes a housing 1 and a driving member 2. A stroke cavity 11 adapted to receive the telescopic shaft 5 is formed in the housing 1. The end of the housing 1 is fitted with the seat body 3. The driving member 2 is movably disposed in the housing 1. The end of the driving member 2 is adapted to abut against the telescopic shaft 5. The driving member 2 is formed with a locking installation cavity 21 for installing a locking ring 6. The locking installation cavity 21 communicates with the end of the driving member 2 and an installation opening 22 communicating with the locking installation cavity 21 is formed on the driving member 2.

[0033] The stroke cavity 11 formed inside the housing 1 can accommodate the telescopic shaft 5, and the end of the housing 1 is fitted with the seat body 3. When installing the spring 4, the telescopic shaft 5 is accommodated in the stroke cavity 11, and the position of the telescopic shaft 5 is effectively defined and will not wobble randomly. The driving member 2 is movably arranged inside the housing 1, and the end of the driving member 2 is adapted to abut against the telescopic shaft 5. During the installation process, by moving the driving member 2, a force can be applied to the telescopic shaft 5. Since the telescopic shaft 5 abuts against the end of the spring 4, this force will be transmitted to the spring 4 to achieve pre-compression of the spring 4. After the spring 4 is pre-compressed, its length becomes shorter and the occupied space decreases, making it less likely to rub against other parts during the installation process. The pre-compressed spring 4 has a certain initial tension and can play its elastic role more stably after being installed in the elastic component 101.

[0034] The function of the locking ring 6 is to resist the rebound of the spring 4. The locking ring 6 can be installed between the telescopic shaft 5 and the seat body 3 and can effectively resist the rebound of the spring 4. After the spring 4 is pre-compressed, without the action of the locking ring 6, the spring 4 is very likely to rebound during the installation process, which will not only increase the installation difficulty but also may cause harm to the operator. By installing the locking ring 6 in a specific position, the pre-compressed state of the spring 4 can be maintained to ensure the smooth progress of the installation process. The locking installation cavity 21 on the driving member 2 provides a dedicated space for installing the locking ring 6. It provides sufficient installation space for the operator, making the installation of the locking ring 6 more convenient and accurate. The operator can operate in this relatively spacious space, avoiding installation difficulties and mistakes caused by the narrow operation space. In the pre-compressed state, the position of the spring 4 is more stable and will not wobble or shift due to its own elastic force. This enables the spring 4 to be more accurately installed into the accommodation cavity 31 of the seat body 3, and the cooperation with the telescopic shaft 5 and other parts is closer, improving the installation accuracy. At the same time, the various parts of the tooling assembly 100 cooperate with each other, making the installation process smoother, reducing the installation time, and improving the installation efficiency.

[0035] Briefly, a tooling component 100 for an elastic component 101 according to an embodiment of the present application. The elastic component 101 has a seat body 3, and a retractable spring 4 can be placed in the accommodating cavity 31 therein. The telescopic shaft 5 in the cavity abuts against the end of the spring 4. The driving member 2 in the tooling component 100 can move within the housing 1, and its end can abut against the telescopic shaft 5. When installing the spring 4, moving the driving member 2 can make its end apply a force to the telescopic shaft 5, and this force is transmitted to the spring 4 to achieve pre-compression. The driving member 2 has a locking installation cavity 21 for installing a locking ring 6. The locking installation cavity 21 communicates with the end of the driving member 2 and has an installation opening 22. Since the spring 4 is restricted within a specific structural range of the tooling component 100, that is, the expansion and contraction of the spring 4 and related operations are carried out in a closed or semi-closed environment composed of the seat body 3, the housing 1, the driving member 2, etc., the spring 4 will not come into contact with other parts randomly in the pre-compressed state. Compared with the traditional installation method, it avoids problems such as installation difficulties and part damage that may be caused by the rubbing of the spring 4 against other parts, thereby making the installation of the spring 4 more convenient and efficient, and improving the reliability and safety of the installation.

[0036] For the tooling component 100 according to some embodiments of the present application, the driving member 2 includes a thrust bushing 23. A locking installation cavity 21 is formed inside the thrust bushing 23. One end of the thrust bushing 23 abuts against the telescopic shaft 5, and an installation opening 22 is formed on the outer peripheral surface of the thrust bushing 23.

[0037] The locking installation cavity 21 formed inside the thrust bushing 23 provides a dedicated space for installing the locking ring 6. During the installation process of the spring 4, after the spring 4 is pre-compressed, the locking ring 6 is installed at the corresponding position through the locking installation cavity 21, thereby effectively resisting the rebound of the spring 4 and maintaining the pre-compressed state of the spring 4. One end of the thrust bushing 23 abuts against the telescopic shaft 5. During the installation process, by applying a force to the thrust bushing 23, the force can be directly transmitted to the telescopic shaft 5, and then transmitted to the spring 4 to achieve pre-compression of the spring 4. Since the thrust bushing 23 is in direct contact with the telescopic shaft 5, the force transmission is more direct and efficient, reducing the loss of force during the transmission process. An installation opening 22 is formed on the outer peripheral surface of the thrust bushing 23. This installation opening 22 provides a convenient channel for the operator to install the locking ring 6. When installing the locking ring 6, the operator can easily place the locking ring 6 into the locking installation cavity 21 through this installation opening 22 without complex operations, greatly improving the installation efficiency.

[0038] For the tooling component 100 according to some embodiments of the present application, an open opening 12 communicating with the stroke cavity 11 is formed on the outer peripheral surface of the housing 1, and at least a part of the open opening 12 is disposed opposite to the installation opening 22.

[0039] An open mouth 12 formed on the outer peripheral surface of the housing 1 and communicating with the stroke cavity 11 and at least a part of it are disposed opposite to the mounting opening 22 on the outer peripheral surface of the thrust sleeve 23, so that during the installation process, the operator can more intuitively observe the internal structure through the open mouth 12 and the opposite mounting opening 22. The installation position and state of the locking ring 6 can be clearly seen, ensuring that the locking ring 6 is correctly installed in the locking installation cavity 21 of the thrust sleeve 23 and the position between the telescopic shaft 5 and the seat body 3 is accurate. At the same time, it is also convenient to observe the pre-compression degree of the spring 4 and the position of the telescopic shaft 5 in the stroke cavity 11, so as to adjust the installation operation in time and ensure the installation accuracy and quality. The opposite setting of the open mouth 12 and the mounting opening 22 provides a larger operating space for installing the locking ring 6. The operator can more conveniently put the locking ring 6 into the locking installation cavity 21 through the open mouth 12 and the mounting opening 22, avoiding installation difficulties and mistakes caused by the narrow operating space. At the same time, during the installation process, if the locking ring 6 needs to be adjusted or replaced, it can also be more easily operated through this open space, improving the installation efficiency and convenience.

[0040] Springs 4 and elastic components 101 of different specifications may require locking rings 6 of different sizes. The design of the open mouth 12 and the mounting opening 22 enables the operator to select a suitable locking ring 6 according to the actual situation and more conveniently install and adjust it. In this way, the tooling assembly 100 can be applicable to more different installation requirements, improving its value in practical applications.

[0041] According to some embodiments of the present application, for the tooling assembly 100, the driving member 2 further includes a handle 24. The end of the handle 24 is connected to the other end of the thrust sleeve 23 and the handle 24 is movably disposed on the housing 1.

[0042] The handle 24 in the driving member 2 is connected to the other end of the thrust bushing 23, and the handle 24 is movably disposed in the housing 1. This enables the operator to conveniently control the movement of the thrust bushing 23 within the housing 1 through the handle 24. The presence of the handle 24 provides the operator with an intuitive and easy-to-operate control component. During the installation process of the spring 4, the operator can easily push or pull the thrust bushing 23 to move within the housing 1 by applying an external force to the handle 24. Notably, the handle 24 has threads, and the handle 24 is threadedly connected to the housing 1. The threads on the handle 24 make the operation more precise and controllable. During the installation process of the spring 4, the operator can rotate the handle 24 and utilize the advancing effect of the threads to control the movement of the thrust bushing 23 within the housing 1. Compared with the traditional direct pushing method, the threaded advancement can provide a more stable and uniform acting force, thereby achieving a more precise pre-compression of the spring 4. The operator can adjust the pre-compression degree of the spring 4 by finely tuning the rotation angle of the handle 24 according to different installation requirements and spring 4 specifications, ensuring that the spring 4 can exhibit the best elastic performance after installation.

[0043] The design of the threads prevents the handle 24 from suddenly slipping or displacing during the advancement process, ensuring that the pressure exerted by the thrust bushing 23 on the spring 4 remains stable at all times. This can avoid situations such as uneven pre-compression of the spring 4 or installation failure caused by unstable pressure, improving the success rate and stability of the installation. After the spring 4 is pre-compressed, a locking ring 6 needs to be installed to maintain the pre-compressed state of the spring 4. The precisely controllable characteristic of the handle 24 allows the operator to more meticulously adjust the position of the thrust bushing 23 as needed during the installation process of the locking ring 6 to better install the locking ring 6.

[0044] The length and shape of the handle 24 can be designed according to ergonomics, enabling the operator to hold the handle 24 more comfortably and safely during the operation, avoiding hand injuries caused by improper operation. Moreover, the threaded advancement method is relatively labor-saving, and the operator can achieve precise control of the thrust bushing 23 with less force, reducing the fatigue and difficulty of the operation.

[0045] For the tooling assembly 100 according to some embodiments of the present application, a first guiding portion 13 is formed on the housing 1, a second guiding portion 25 that cooperates with the first guiding portion 13 is formed on the thrust bushing 23 to limit the thrust rotation, and the handle 24 is rotatably connected to the thrust bushing 23.

[0046] Due to the cooperation of the first guiding portion 13 and the second guiding portion 25, the thrust bushing 23 can only move linearly within the housing 1. During the installation process of the spring 4, when the handle 24 pushes the thrust bushing 23, the thrust bushing 23 will not rotate, ensuring that the force exerted by the thrust bushing 23 on the telescopic shaft 5 always acts along a fixed direction. If the thrust bushing 23 could rotate with the handle 24, then during the force application process, there would not only be a thrust force but also a rotational force of the thrust bushing 23, resulting in uneven pre-compression of the spring 4 and potentially damaging the spring 4 or other components. Therefore, restricting the rotation of the thrust bushing 23 can ensure the accuracy and stability of the pre-compression of the spring 4.

[0047] Meanwhile, because the thrust bushing 23 does not rotate with the handle 24, when the operator observes through the open opening 12 on the housing 1, the position of the locking installation cavity 21 is relatively fixed. If the thrust bushing 23 rotated with the handle 24, then the position of the locking installation cavity 21 would constantly change, making it difficult for the operator to accurately observe the installation condition of the locking ring 6 and its mating state with other components. This enables the operator to more clearly understand every detail during the installation process, promptly discover problems and make adjustments, thereby improving the installation efficiency and quality.

[0048] It should be noted that the first guiding portion 13 is a threaded section at the connection between the handle 24 and the housing 1, and the second guiding portion 25 can be configured as a bearing assembly. The bearing assembly can include a deep groove ball bearing, a snap ring for the hole, and a snap ring for the shaft. The deep groove ball bearing is installed between the thrust bushing 23 and the handle 24, and is respectively installed in the inner cavity of the thrust bearing through the snap ring for the hole and installed on the outer shaft of the handle 24 through the snap ring for the shaft to fix the deep groove ball bearing. The function of the bearing assembly is to ensure that when the thrust screw rotates in the thread, the thrust bushing 23 does not rotate with the handle 24, facilitating the installation of the stop ring of the spring 4.

[0049] According to the tooling assembly 100 of some embodiments of the present application, an annular receiving groove 51 is formed at the end of the telescopic shaft 5. The receiving groove 51 is adapted to cooperate with the end of the thrust bushing 23 and the locking ring 6 is adapted to be received in the receiving groove 51.

[0050] When the spring 4 is compressed, the locking ring 6 is placed in the receiving groove 51 through the locking installation cavity 21, and the position of the locking ring 6 is clearly defined. The locking ring 6 will not move randomly due to external factors, ensuring the stability of the spring 4 during the pre-compression process and making the locking ring 6 more stable and reliable when it plays a role.

[0051] The structure of the locking ring 6 is a circular ring with a partial opening. After the locking ring 6 is installed in the receiving groove 51, since the size of the receiving groove 51 is smaller than that of the locking ring 6, in order for the locking ring 6 to restore its original opening size, the locking ring 6 has a tendency to expand outwards. After the spring 4 is compressed in place, the locking ring 6 can expand in accordance with its tendency to expand outwards. This expansion action enables the locking ring 6 to fit more closely with the surrounding structure, further enhancing the locking effect on the spring 4. Compared with traditional locking methods, this design can better prevent the spring 4 from rebounding after installation, ensuring that the spring 4 is always in a pre-compressed state, providing a stable elastic force for subsequent use. At the same time, this expansion locking method is more convenient to operate, without the need for complex additional operations, improving the installation efficiency and convenience.

[0052] For the tooling assembly 100 according to some embodiments of the present application, a first limiting and mating portion 14 is formed at the end of the housing 1, and a second limiting and mating portion 33 adapted to be limited and mated with the first limiting and mating portion 14 is formed on the seat body 3.

[0053] When assembling or disassembling, the first limiting and mating portion 14 and the second limiting and mating portion 33 can accurately guide the docking of the housing 1 and the seat body 3. The operator can easily connect the housing 1 and the seat body 3 through these two mating portions without complex alignment operations. This clear limiting and mating makes the assembly process more efficient and accurate, reducing the assembly time and labor costs.

[0054] It should be noted that the first mating portion and the second mating portion are connected by threads. When the first limiting and mating portion 14 of the housing 1 and the second limiting and mating portion 33 of the seat body 3 are connected together by threads, the connection between the housing 1 and the seat body 3 is ensured to be firm and stable. During the installation and use of the spring 4, it will not be easily separated due to the action of external forces. The stable connection provides a solid foundation for the normal operation of the spring 4, ensuring the reliability of the entire tooling assembly 100. Threaded connection can achieve precise positioning and alignment. During the installation process, by rotating the housing 1 or the seat body 3, the first limiting and mating portion 14 and the second limiting and mating portion 33 can be gradually screwed together, thereby ensuring the accurate position of both. This helps to ensure the position accuracy of the spring 4 during the installation process, enabling the spring 4 to play its role in the correct position, improving the installation accuracy and consistency.

[0055] Next, the elastic component 101 according to the embodiments of the present application will be briefly described.

[0056] The elastic component 101 according to an embodiment of the present application is the elastic component 101 assembled for the tooling component 100 of any of the above embodiments. The elastic component 101 includes a seat body 3, a spring 4, and a telescopic shaft 5. An accommodation cavity 31 adapted to accommodate the spring 4 is formed in the seat body 3. The spring 4 is telescopically disposed in the accommodation cavity 31. The telescopic shaft 5 is received in the accommodation cavity 31 and passes through the spring 4. The end of the telescopic shaft 5 is connected to the driving member 2; a locking ring 6 is disposed between the telescopic shaft 5 and the seat body 3.

[0057] In the elastic component 101 according to an embodiment of the present application, since the telescopic shaft 5 is received in the accommodation cavity 31 and passes through the spring 4 and is connected to the driving member 2, with the cooperation of the tooling component 100, the spring 4 can be effectively pre-compressed during the installation process. This pre-compression operation is carried out in the seat body 3. The seat body 3 and the telescopic shaft 5 limit the compression or stretching path of the spring 4, avoiding unnecessary rubbing between the spring 4 and other parts during the installation process, and greatly improving the installation convenience. The locking ring 6 is disposed between the telescopic shaft 5 and the seat body 3, and it can play an auxiliary fixing role during the installation process, further ensuring the relative position stability of each component, reducing the uncertainty during the installation process, and making the assembly process of the entire elastic component 101 smoother and more efficient.

[0058] In the elastic component 101 according to some embodiments of the present application, the seat body 3 forms a mating groove 32 on the inner wall of the accommodation cavity 31. The mating groove 32 is disposed adjacent to the end of the housing 1. The end of the telescopic shaft 5 forms an annular receiving groove 51. The receiving groove 51 is adapted to be aligned with the mating groove 32, and the locking ring 6 cooperates with the receiving groove 51 and the mating groove 32 respectively to lock the seat body 3 and the telescopic shaft 5.

[0059] The locking ring 6 is respectively engaged with the annular receiving groove 51 at the end of the telescopic shaft 5 and the mating groove 32 on the inner wall of the receiving cavity 31 of the seat body 3, realizing the locking of the seat body 3 and the telescopic shaft 5. The locking ring 6 ensures a tight connection between the seat body 3 and the telescopic shaft 5, and there will be no loosening or relative displacement during the telescopic process of the spring 4. When the elastic component 101 works, the repeated telescopic movement of the spring 4 will generate a continuous acting force. Without reliable locking, the seat body 3 and the telescopic shaft 5 may gradually separate, affecting the normal operation of the elastic component 101. The existence of the locking ring 6 makes the seat body 3 and the telescopic shaft 5 form a stable whole, which can withstand the forces in various working states, greatly improving the stability and reliability of the elastic component 101. The locking ring 6 provides positioning and fixation for the installation process. Since the locking ring 6 has a tendency to expand outwards, after the receiving groove 51 and the mating groove 32 are aligned, the locking ring 6 can expand from the receiving groove 51 to be connected with the mating groove 32. Through the locking ring 6, any relative displacement between the seat body 3 and the telescopic shaft 5 can be effectively prevented, ensuring the structural stability of the entire elastic component 101. Even when a large acting force is generated due to the continuous telescopic movement of the spring 4, this connection can be firmly maintained, enabling the elastic component 101 to work continuously and stably.

[0060] When maintenance or replacement of the spring 4 of the elastic component 101 is required, simply disconnect the locking ring 6, and the seat body 3 and the telescopic shaft 5 can be separated. This greatly simplifies the maintenance and replacement process, reducing the operation difficulty and cost. Moreover, the reusable nature of the locking ring 6 also makes the maintenance of the elastic component 101 more convenient and efficient.

[0061] According to some embodiments of the present application, for the elastic component 101, the inner wall of the receiving groove 51 is configured as an arc-shaped recess towards the end of the spring 4.

[0062] The inner wall of the arc-shaped receiving groove 51 is beneficial to the installation and operation of the locking ring 6. When the locking ring 6 expands from the receiving groove 51 to connect with the mating groove 32, the inner wall of the arc-shaped receiving groove 51 can provide a better guiding effect for the locking ring 6. Due to the arc shape having a certain curvature, it provides a directional path for the expansion of the locking ring 6. During the expansion process of the locking ring 6, its edge can gradually move outward along the arc-shaped inner wall, ensuring that the locking ring 6 expands in the correct direction, that is, towards the direction of connection with the mating groove 32. In contrast, if the inner wall of the receiving groove 51 is of other irregular shapes or without such arc-shaped guidance, the locking ring 6 may deviate in direction during expansion. For example, it may deviate to one side or be skewed, which will make it difficult for the locking ring 6 to accurately connect with the mating groove 32 and may even prevent the connection operation from being completed. When the locking ring 6 has not yet expanded from the receiving groove 51 to connect with the mating groove 32, the arc shape can better wrap part of the structure of the locking ring 6 and prevent the locking ring 6 from coming out. The locking ring 6 can achieve close fitting with the arc-shaped inner wall at multiple contact points, making the positioning of the locking ring 6 in the receiving groove 51 more accurate and stable.

[0063] It should be noted that one end of the telescopic shaft 5 is the shaft end and the other end is the bearing end. The spring 4 is sleeved on the shaft end, the bearing end abuts against the driving part 2, the seat body 3 is provided with an opening adapted to the shaft end, and the shaft end can slide in the opening along the telescopic direction of the spring 4. Among them, a receiving groove 51 is provided on the bearing end, and two symmetrically arranged positioning bosses are provided on the bearing end. A positioning groove matching the positioning boss is formed on one side of the seat body 3 close to the tooling component 100. After the positioning boss and the positioning groove are positioned, it is convenient for the subsequent installation of the locking ring 6.

[0064] The assembly process of the tooling component 100 is briefly described below. First, the deep groove ball bearing is press-fitted into the bearing installation hole of the thrust shaft sleeve 23 until the step surface abuts, and the hole retaining ring is installed in the card slot through a tool, so as to fix the deep groove ball bearing on the thrust shaft sleeve 23; next, the external thread of the handle 24 is matched with the internal thread on the housing 1, and the front end small shaft of the handle 24 leaks out of the open opening 12 of the housing 1; finally, the thrust shaft sleeve 23 with the bearing is installed into the housing 1 from the open opening 12, and the inner ring of the bearing is installed in transitional fit with the front end small shaft of the thrust screw until the step surfaces contact, and the shaft retaining ring is installed in the card slot through a tooling, so that the thrust shaft sleeve 23 and the thrust screw are connected into one body, but the handle 24 can be rotated independently.

[0065] The operation method of the tooling component 100 is briefly described below. First, install the spring 4 into the inner cavity of the seat body 3, then pass the telescopic shaft 5 through the inner cavity of the spring 4, and the end shaft of the telescopic shaft 5 is fitted with the opening of the seat body 3. Next, clamp the outer circle of the assembled seat body 3 on the bench vice to ensure fixation. The spring 4 is fixedly installed on the tooling and the seat body 3 is fixed by the matching of the first limiting and matching part 14 on the housing 1 and the second limiting and matching part 33 of the seat body 3. Then, drive the thrust shaft sleeve 23 to move forward in the direction of the telescopic shaft 5 by rotating the handle 24 until the end face of the thrust shaft sleeve 23 abuts against the groove surface of the telescopic shaft 5, and rotate the telescopic shaft 5 by hand to adjust its position to ensure that the two positioning bosses of the telescopic shaft 5 and the positioning grooves of the seat body 3 are on the same plane. Synchronously, keep the locking installation cavity 21 of the thrust shaft sleeve 23 in the same direction as the open port 12 on the housing 1. Finally, by rotating the handle 24 of the thrust screw, the thrust shaft sleeve 23 acts on the telescopic shaft 5 to start compressing the spring 4 until the rear end face of the positioning boss of the telescopic shaft 5 completely enters the seat body 3. Install the locking ring 6 on the receiving groove 51 at the end of the telescopic shaft 5, and continue to compress the spring 4 until the locking ring 6 contacts and rebounds with the mating groove 32, and the locking ring 6 cooperates with the receiving groove 51 and the mating groove 32 respectively to lock the seat body 3 and the telescopic shaft 5.

[0066] After the locking is in place, rotate the handle 24 in the reverse direction, the thrust shaft sleeve 23 moves backward away from the end face of the telescopic shaft 5, and then unscrew the first mating part and the second mating part, and the tooling component 100 can be disassembled.
