Description

Technical Field

[0001] This utility model belongs to the field of board corner cutting, specifically relating to a board multi-sided corner cutting device applied to a corner cutting machine. Background Technology

[0002] In the current sheet metal processing industry, the multi-sided corner cutting operation of sheets usually relies on manual adjustment and fixing of the sheet position. This method is not only inefficient, but also makes it difficult to guarantee cutting accuracy, specifically in the following aspects:

[0003] 1. Large errors in manual positioning: Since the adjustment and fixing of the board position depends on manual labor, the operator's skill level and experience directly affect the final positioning accuracy of the board; even experienced workers cannot avoid small errors, and these errors accumulate and will cause the final product to fail to meet the specifications.

[0004] 2. Low production efficiency: Manually adjusting the position of the boards takes a lot of time, especially when dealing with large batches or complex shapes of boards, the efficiency problem is more prominent; each adjustment requires recalibration and verification of the board position, which greatly limits the overall output speed of the production line.

[0005] 3. Low positioning accuracy: During the diagonal pushing and cutting process of the board, the board often affects the cutting accuracy due to insufficient movement distance. At the same time, it cannot adapt to the cutting needs of boards of different sizes and shapes, which has certain limitations and cannot guarantee the final product cutting quality. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a multi-sided corner cutting device for corner cutting machines that has a simple overall structure, reduces the difficulty of operation, achieves fast and stable plate positioning and pushing, and improves the overall corner cutting accuracy.

[0007] The technical solution adopted by this utility model to solve its technical problem is to propose a multi-sided corner cutting device for a corner cutting machine, including: a frame with length and width, wherein corner cutting machines are correspondingly arranged on the right-angle sides formed by the length and width of the frame, for cutting corners of the board one by one;

[0008] A lateral drive mechanism and a longitudinal drive mechanism with a height difference are arranged in a cross shape within the frame. The lateral drive mechanism is arranged along the length direction parallel to the frame; the longitudinal drive mechanism is arranged along the width direction parallel to the frame.

[0009] The machine includes a transverse pushing mechanism and a longitudinal pushing mechanism. Each transverse driving mechanism has at least two transverse pushing mechanisms symmetrically distributed on both sides of the longitudinal driving mechanism at its output end, used to push the sheet metal along the length of the frame. Each longitudinal driving mechanism also has at least two longitudinal pushing mechanisms symmetrically distributed on both sides of the transverse driving mechanism at its output end, used to push the sheet metal along the width of the frame.

[0010] Both the transverse pushing mechanism and the longitudinal pushing mechanism include a first stroke detection component and a second stroke detection component symmetrically distributed on both sides. The first stroke detection component can retract along its interior when it comes into contact with the board, so that the board can contact and squeeze the second stroke detection component, so that the position of the board to be cut is accurately extended into the corner cutting machine.

[0011] In the aforementioned multi-sided corner cutting device for sheet metal applied to a corner cutting machine, the first stroke detection component includes:

[0012] A movable base has a fixed block at its central position. The movable base has a guide hole, and the fixed block has a through hole. The guide hole and the through hole are coaxially arranged.

[0013] A movable column, one end of which is movably inserted into the guide hole, and the other end of which movably passes through the through hole, and the end of the movable column is also connected to a contact head with an outer diameter larger than the inner diameter of the through hole;

[0014] A first elastic element and a sensor are provided. The first elastic element is movably sleeved on the movable column, with one end connected to the movable seat and the other end connected to the fixed block. The sensor is aligned with the guide hole to detect the displacement of the movable column relative to the movable seat.

[0015] In the aforementioned multi-sided corner cutting equipment for sheet metal applied to a corner cutting machine, both the transverse pushing mechanism and the longitudinal pushing mechanism further include a locking member. The fixed block forms an extension block along the side away from the moving seat. The locking member is movably connected to the transverse driving mechanism or the longitudinal driving mechanism and is detachably connected to the bottom wall of the extension block.

[0016] In the aforementioned multi-sided corner cutting device for sheet metal applied to a corner cutting machine, the second stroke detection component includes:

[0017] Fixed columns are symmetrically distributed on both sides of the fixed block and connected to the movable seat;

[0018] A movable plate is movably sleeved on the fixed column, and each movable plate has a guide block connected to its top and bottom ends. The guide blocks slide against the top and bottom walls of the movable base, respectively.

[0019] The second elastic element has one end connected to the movable base and the other end connected to the movable plate;

[0020] A roller has a connecting shaft formed along its axial direction, and the connecting shaft is movably connected within the guide block.

[0021] In the aforementioned multi-sided corner cutting equipment for sheet metal applied to a corner cutting machine, there is a distance difference between the contact head and the roller relative to the moving seat.

[0022] In the aforementioned multi-sided corner cutting device for sheet metal applied to a corner cutting machine, both the transverse drive mechanism and the longitudinal drive mechanism include:

[0023] A driving component is mounted on the frame, and the driving end of the driving component is connected to an output shaft;

[0024] A driving wheel and a driven wheel are provided. The driving wheel is connected to the output shaft. An assembly block is provided on the frame. The driven wheel is provided with a rotating shaft along its axial direction. The rotating shaft is movably connected to the assembly block.

[0025] The conveyor belt, the driving wheel and the driven wheel are connected by the conveyor belt, and at least two of the locking elements are connected on each of the conveyor belts.

[0026] In the aforementioned multi-sided corner cutting equipment for sheet metal applied to a corner cutting machine, a support plate is also provided on the frame, and several fixed seats are arranged in an array on the support plate. Each fixed seat is movably provided with a ball bearing for supporting the sheet metal.

[0027] In the aforementioned multi-sided corner cutting equipment for sheet metal applied to a corner cutting machine, the locking component includes a connecting block and an anti-detachment block. The connecting block has a locking hole, and the extension block has a connecting hole. When the locking hole and the connecting hole are aligned and connected, they can be connected by fasteners. The anti-detachment block has a plurality of protruding teeth arranged in an array at equal intervals. The protruding teeth and the connecting block can be connected to the conveyor belt when they are pressed together.

[0028] In the aforementioned multi-sided corner cutting equipment for sheet metal applied to a corner cutting machine, a tensioning wheel and a connecting rod are also provided on the conveyor belt. The connecting rod is connected to the tensioning wheel and is used to adjust the tension of the tensioning wheel on the conveyor belt.

[0029] In the aforementioned multi-sided corner cutting equipment for sheet metal applied to a corner cutting machine, a plurality of adjusting columns are movably arranged on the frame, and each adjusting column is connected to a support foot at its bottom end. The plurality of support feet can contact the ground when the adjusting column moves relative to the frame, so that the frame maintains a horizontal posture.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) This utility model provides a multi-sided corner cutting device for plates applied to corner cutting machines. By precisely controlling the movement of the plate in the horizontal and vertical directions and the two-stage stroke detection design, it ensures that the plate can be cut at the most accurate position every time, which greatly improves the cutting accuracy. The whole process realizes the automated plate positioning, pushing and corner cutting functions, reducing the need for manual intervention. At the same time, it is suitable for the corner cutting needs of plates of various sizes and shapes, enhancing the versatility and flexibility of the equipment.

[0032] (2) The ball bearings on the support plate can ensure that the plate moves more smoothly during the transfer process, avoiding collisions or wear caused by jamming. At the same time, the support plate divides the moving areas of the transverse and longitudinal pushing mechanisms, ensuring that there is no positional interference between the components, thus guaranteeing the smoothness and stability of the equipment during operation.

[0033] (3) By adjusting the position of the column relative to the frame, several support feet can be in contact with the ground at the same time, ensuring that the frame always maintains a horizontal posture, effectively enhancing the stability and safety of the entire feeding mechanism, reducing vibration or shaking caused by imbalance, and suitable for different working environments.

[0046] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0047] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0048] like Figures 1 to 5As shown, this utility model discloses a multi-sided corner cutting device for sheet metal applied to a corner cutting machine 10, comprising: a frame 1 having length and width, with corner cutting machines 10 corresponding to the right angles formed by the length and width of the frame 1, used to cut corners of sheet metal one by one; a transverse drive mechanism 2 and a longitudinal drive mechanism 3 having a height difference, arranged in a cross shape within the frame 1, the transverse drive mechanism 2 being arranged along the length direction parallel to the frame 1; a longitudinal drive mechanism 3 being arranged along the width direction parallel to the frame 1; a transverse pushing mechanism 5 and a longitudinal pushing mechanism 6, each of the transverse drive mechanism 2 having at least two symmetrically distributed on the longitudinal drive mechanism 6 at its output end. The transverse pushing mechanisms 5 on both sides of the mechanism 3 are used to push the plate to move along the length direction of the frame 1; each longitudinal driving mechanism 3 has at least two longitudinal pushing mechanisms 6 symmetrically distributed on both sides of the transverse driving mechanism 2 at its output end, which are used to push the plate to move along the width direction of the frame 1; wherein, the transverse pushing mechanism 5 and the longitudinal pushing mechanism 6 each include a first stroke detection component 70 and a second stroke detection component 71 symmetrically distributed on both sides of it. The first stroke detection component 70 can retract along its interior when it comes into contact with the plate so that the plate can contact and squeeze the second stroke detection component 71, so that the position of the plate to be cut is accurately extended into the corner cutting machine 10.

[0049] In this embodiment, four cutting machines are used to cut the four corners of the board. Specifically, as shown below... Figure 1 As shown, firstly, an external robotic arm (not shown in the figure) places the sheet metal to be cut onto the frame 1. Before this, the transverse drive mechanism 2 and the longitudinal drive mechanism 3 have pre-adjusted the initial positions of the transverse push mechanism 5 and the longitudinal push mechanism 6 according to the size of the sheet metal, ensuring that the sheet metal can be placed in the cutting area of ​​the frame 1 without positional interference. The following only describes... Figure 1 The following explains the corner-cutting operation of the cutting machine in the lower left corner (all other cutting operations are the same and will not be described in detail here): When the material is placed on the frame 1, the longitudinal pushing mechanism 6 can push the material along the width (W) direction of the frame 1 towards the cutting machine (all referring to the cutting machine). Figure 1Approaching from the lower left, during this process, when the board comes into contact with the first stroke detection component 70, while the board moves along the width direction of the frame 1, the first stroke detection component 70 will be forced to retract due to the reaction force brought by the weight of the board itself, until the board continues to move forward until it touches and squeezes the second stroke detection component 71. The two-stroke operation steps ensure that the position of the board to be cut can be accurately aligned with the cutting position of the corner cutting machine 10, improving the cutting accuracy. Similarly, with the driving force of the transverse pushing mechanism 5 along the length (L) direction of the transverse driving mechanism 2 along the frame 1, accompanied by the same two-stroke detection, the position of the board to be cut can be accurately extended into the cutting position of the corner cutting machine 10. By repeating the above operation, the corner cutting machine 10 at different positions can be used to cut the board at different positions one by one, and finally the automatic unloading operation of the product is completed by the robot again. Therefore, by utilizing the first stroke detection component 70 and the second stroke detection component 71, each board can enter the corner cutting area at the most precise position, which greatly improves the cutting accuracy and avoids the overall cutting quality being affected by positional deviations during board movement. At the same time, the design of the height difference between the transverse drive mechanism 2 and the longitudinal drive mechanism 3 avoids positional interference between the push mechanisms at various positions during movement. The entire corner cutting process does not require manual intervention. From board positioning and detection to the final corner cutting, the entire process is automated, reducing labor costs and minimizing errors caused by human factors.

[0050] The first stroke detection component 70 includes: a movable base 700, with a fixed block 701 disposed in its middle position; a guide hole 702 is provided in the movable base 700; a through hole 703 is provided in the fixed block 701; the guide hole 702 and the through hole 703 are coaxially arranged; a movable column 704, one end of which is movably inserted into the guide hole 702, and the other end of which movably passes through the through hole 703; a contact head 705 with an outer diameter larger than the inner diameter of the through hole 703 is also connected to the end of the movable column 704; a first elastic element 706 and a sensor 707; the first elastic element 706 is movably sleeved on the movable column 704, and one end of the first elastic element 706 is connected to the movable base 700, and the other end is connected to the fixed block 701; the sensor 707 is aligned with the guide hole 702 and is used to detect the displacement of the movable column 704 relative to the movable base 700.

[0051] Furthermore, such as Figures 2 to 4As shown, when there is no contact with the plate, one end of the moving column 704 is held in a preset initial position by the action of the first elastic element 706, and the contact head 705 on the moving column 704 is located outside the fixed block 701, while the sensor 707 is aligned with the guide hole 702 to detect the displacement generated by the moving column 704. When the contact head 705 contacts the plate and applies its movement along the width direction of the frame 1, the contact head 705 is subjected to the reverse extrusion force of the plate, causing the moving column 704 to overcome the elastic force of the first elastic element 706 and retract into the guide hole 702. As the plate is further advanced, the moving column 704 continues to move inward until the plate completely abuts against the second stroke detection component 71. It is worth noting that each displacement of the moving column 704 is accurately captured by the sensor 707 and the information is converted into an electrical signal and transmitted to the control system. The control system calculates the exact position of the plate and the distance to be adjusted based on the received information to ensure that the plate accurately enters the working area of ​​the corner cutting machine 10. It is precisely by using the sensor 707 to monitor the displacement of the moving column 704 in real time that the position of the plate can be determined very accurately, thereby ensuring that each corner cutting operation can achieve extremely high accuracy. No matter how the thickness of the plate changes (important), the structure can adapt through the cooperation of the moving column 704 and the first elastic element 706 to ensure that plates of different specifications can be positioned and cut consistently and accurately.

[0052] Preferably, the sensor 707 in this embodiment can be replaced by other devices that can achieve the above functions, such as a laser sensor or a position sensor.

[0053] The second stroke detection component 71 includes: fixed posts 710, symmetrically distributed on both sides of the fixed block 701 and connected to the movable seat 700; movable plates 711, which are movably sleeved on the fixed posts 710, and each movable plate 711 has a guide block 712 connected to its top and bottom ends, and the guide blocks 712 are slidably attached to the top and bottom walls of the movable seat 700 respectively; a second elastic member 713, one end of which is connected to the movable seat 700 and the other end of which is connected to the movable plate 711; and a roller 714, with a connecting shaft 715 formed along its axial direction, and the connecting shaft 715 is movably connected to the guide block 712.

[0054] More preferably, such as Figures 2 to 5As shown, similarly, when there is no contact with the plate, the moving plate 711 is held in a preset initial position by the action of the second elastic element 713. At this time, the roller 714 is in a ready position and can rotate freely. When the plate is pushed to the contact roller 714 by the transverse or longitudinal pushing mechanism 6, if the sensor 707 detects that the plate is not yet aligned with the cutting position (or the displacement of the moving column 704 has not reached the required level), the plate will continue to move forward and apply a squeezing force to the roller 714. At this time, the moving plate 711 will overcome the elastic force of the second elastic element 713 and slide inward along the fixed column 710. At the same time, the plate is still synchronously squeezing the moving column 704 to retract into the moving seat 700. Finally, the data of the second stroke detection is obtained by the sensor 707 in conjunction with the external control system (not shown in the figure) to obtain the corresponding positioning stroke value. Preferably, in this embodiment, there is a distance difference between the contact head 705 and the roller 714, allowing for gradual adjustment of the plate's position in two different stages (equivalent to coarse positioning and precise positioning). This enables more precise control over the final cutting position of the plate. The staged positioning method avoids the impact or wear problems that may be caused by direct hard contact, extending the equipment's service life. Once the plate has been cut and removed from its position, the elastic reset of the first elastic element 706 and the second elastic element 713 allows the moving column 704 and the roller 714 to be pushed back to their initial positions, preparing for the processing of the next plate. By combining the two-stage stroke detection of the moving plate 711 and the moving column 704, the accuracy of plate positioning is effectively improved, ensuring that each corner cutting operation achieves the desired effect.

[0055] More preferably, since the roller 714 can rotate freely around its connecting shaft 715, the friction force on the plate is minimized when it comes into contact with the roller 714. At the same time, when the transverse pushing mechanism 5 pushes the plate to move along the length of the frame 1, the roller 714 and the side wall of the plate are in sliding friction. The roller 714 can provide guidance and limiting functions for the plate during its movement, so that the plate can enter the cutting position more smoothly.

[0056] More preferably, in this embodiment, during the process of the moving plate 711 contracting by compressing the second elastic element 713, the two guide blocks 712 are tightly attached to the top and bottom walls of the moving seat 700, respectively, ensuring that the moving plate 711 can only slide along the axial direction of the fixed column 710. This effectively avoids the moving plate 711 tilting during movement and causing jamming, ensuring the accuracy of the two stroke displacements detected by the sensor 707, further increasing the stability and reliability of the device, and reducing errors caused by external forces.

[0057] Both the transverse drive mechanism 2 and the longitudinal drive mechanism 3 include: a drive member 40, which is mounted on the frame 1, and the drive end of the drive member 40 is connected to an output shaft 41; a drive wheel 42 and a driven wheel 43, wherein the drive wheel 42 is connected to the output shaft 41, an assembly block 11 is mounted on the frame 1, and the driven wheel 43 is provided with a rotating shaft 430 along its axial direction, the rotating shaft 430 being movably connected to the assembly block 11; and a conveyor belt 44, wherein the drive wheel 42 and the driven wheel 43 are connected through the conveyor belt 44, and at least two locking members 72 are connected to each conveyor belt 44.

[0058] Specifically, such as Figure 2 As shown, when the sheet material needs to be positioned or moved, the control system activates the drive component 40 in the transverse or longitudinal drive mechanism 3. The drive component 40 directly drives the drive wheel 42 to rotate via the output shaft 41, which in turn drives the driven wheel 43 to rotate via the connected conveyor belt 44. The conveyor belt 44 forms a closed loop between the drive wheel 42 and the driven wheel 43, ensuring that the power can be evenly transmitted to the entire system. It is worth noting that each conveyor belt 44 is connected to at least two locking components 72, that is, each conveyor belt 44 is equipped with at least two transverse pushing mechanisms 5 or longitudinal pushing mechanisms 6. In this embodiment, each Two locking mechanisms 72 are provided on each conveyor belt 44, and the two transverse pushing mechanisms 5 or longitudinal pushing mechanisms 6 on the same conveyor belt 44 are spaced apart (i.e., the distance between them is enough to allow the sheet material to be placed on the frame 1). As the conveyor belt 44 rotates, the two locking members 72 move synchronously. The difference is that only one longitudinal pushing mechanism 6 or one transverse pushing mechanism 5 on one conveyor belt 44 applies the force to move the sheet material. Therefore, under the pushing force acting on different side walls of the sheet material, the cutting operation of the corner cutting machine 10 at different diagonal positions of the sheet material is realized. No manual intervention is required throughout the process, which reduces labor intensity and significantly improves production efficiency. Preferably, the driving component 40 in this embodiment can be replaced by other driving devices such as stepper motors and servo motors.

[0059] Preferably, in this embodiment, several sets of longitudinal pushing mechanisms 6 at different positions can be arranged along the length of the frame 1 to adapt to the corner cutting process of plates of different specifications and shapes, thereby enhancing the applicability of the equipment and improving its flexibility. Meanwhile, to ensure the synchronous movement of the several sets of longitudinal pushing mechanisms 6, a coupling can be used to connect adjacent output shafts 41, ensuring that the plate does not shift or tilt during positioning and movement, thus affecting the cutting accuracy of the subsequent cutting machine.

[0060] Both the transverse pushing mechanism 5 and the longitudinal pushing mechanism 6 also include a locking member 72. The fixed block 701 forms an extension block 708 on the side away from the movable seat 700. The locking member 72 is movably connected to the transverse driving mechanism 2 or the longitudinal driving mechanism 3 and is detachably connected to the bottom wall of the extension block 708.

[0061] Furthermore, such as Figure 2 As shown, in order to achieve a stable conveying connection between the drive mechanism and the pushing mechanism, this embodiment utilizes a locking mechanism between the locking member 72 and the transverse drive mechanism 2 or the longitudinal drive mechanism 3. This effectively prevents positional deviations caused by unexpected vibrations or external forces during the positioning and movement of the sheet material, thus ensuring the quality of the sheet material in subsequent cutting. Furthermore, this embodiment employs a detachable connection method, making the locking member 72 easy to install and remove, facilitating daily inspection and maintenance, reducing downtime, and improving work efficiency.

[0062] The locking component 72 includes a connecting block 720 and an anti-detachment block 721. The connecting block 720 has a locking hole, and the extension block 708 has a connecting hole 708a. When the locking hole and the connecting hole 708a are aligned and connected, they can be connected by fasteners. The anti-detachment block 721 has a number of protrusions 721a arranged in an array at equal intervals. The protrusions 721a and the connecting block 720 can be connected to the conveyor belt 44 when they are pressed together.

[0063] More preferably, such as Figure 2 As shown, the precise alignment of the locking hole (not shown) with the connecting hole 708a and the use of fasteners ensure the stability of the plate during positioning and movement, preventing any possible positional deviation and significantly improving cutting accuracy. The protruding teeth 721a on the anti-detachment block 721 increase the friction between the locking element 72 and the conveyor belt 44, while also providing a mechanical anti-detachment mechanism, effectively preventing the locking element 72 from accidentally falling off during high-intensity operation and increasing the safety of the equipment during operation. Preferably, the locking hole is a threaded hole, and the fasteners in this embodiment can be replaced by screws, bolts, or other connecting components to achieve a detachable connection, facilitating daily maintenance and troubleshooting, and reducing downtime.

[0064] In a further preferred embodiment, a tensioning wheel 45 and a connecting rod 46 are also provided on the conveyor belt 44. The connecting rod 46 is connected to the tensioning wheel 45. During the operation of the equipment, as the usage time increases and the ambient temperature changes, the conveyor belt 44 may become loose. At this time, the position of the tensioning wheel 45 can be finely adjusted using the connecting rod 46 to maintain the optimal tension. Appropriate tension can prevent the conveyor belt 44 from slipping between the driving wheel 42 and the driven wheel 43, ensuring that power can be efficiently transmitted to the entire system, improving the overall work efficiency. At the same time, with regular adjustment of tension, wear caused by the conveyor belt 44 being too tight or too loose can be effectively reduced, extending its service life and reducing the replacement frequency and maintenance costs.

[0065] The frame 1 is also provided with a support plate 12, and a number of fixed seats 120 are arranged in an array on the support plate 12. Each fixed seat 120 is movably provided with a ball bearing 121 for supporting the plate 12.

[0066] More preferably, such as Figure 1 As shown, in this embodiment, the support plate 12 not only avoids positional interference with the locking member 72 as it moves with the conveyor belt 44, but also limits the displacement of the locking member 72 relative to the frame 1 by fixing the support plate 12 to the frame 1. This ensures that both locking members 72 on the conveyor belt 44 are above the conveyor belt 44, preventing one locking member 72 from tilting or rotating below the conveyor belt 44 due to excessive displacement. The design of the ball bearing 121 greatly reduces the friction between the plate and the support plate 12, providing uniform support while allowing the plate to move more smoothly, avoiding movement or deformation of the plate caused by external forces, and improving the cutting quality.

[0067] Several adjusting columns 13 are movably installed on the frame 1. Each adjusting column 13 is connected to a support foot 14 at its bottom end. The support feet 14 can contact the ground when the adjusting column 13 moves relative to the frame 1, so that the frame 1 maintains a horizontal posture.

[0068] More preferably, such as Figure 1 As shown, ground conditions often vary in factory workshops and other working environments. By adjusting the position of the adjusting column 13 relative to the frame 1, the support feet 14 at each position can contact the ground, ensuring that the levelness of the entire equipment meets the usage requirements. Therefore, this design can adapt to various ground conditions (such as slightly uneven ground), expanding the application range of the equipment. It should be noted that in this embodiment, the position adjustment of the support feet 14 can be achieved through a threaded connection between the adjusting column 13 and the frame 1.

[0069] It should be noted that the first elastic element 706 and the second elastic element 713 in this embodiment can both be replaced by other elastic devices such as compression springs and return springs.

[0070] It should be noted that in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly defined. The terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly defined.
