Description

Technical Field

[0001] This utility model relates to the field of valve seat quality inspection technology, specifically to an adaptive multi-specification valve seat clamping mechanism, a runout detection device and system. Background Technology

[0002] Engine valve seats are one of the key components of an engine, and their quality directly affects the engine's performance and reliability. Valve seat runout testing is a crucial part of quality control. Accurate runout testing can effectively prevent problems such as air leakage and accelerated wear caused by valve seat installation misalignment, ensuring that the engine maintains a highly efficient and stable operating condition during long-term operation.

[0003] In actual production, there are various specifications of valve seat rings, and the main difference between these different specifications lies in their outer diameter. To meet the runout detection requirements of valve seat rings of various specifications, some automatic valve seat ring testing machines of various specifications have been put into use. For example, the testing machine disclosed in patent publication number CN218443587U includes a base, a groove on the top surface of the base, a cavity in the bottom wall of the groove, and a positioning screw engaged with the side wall of the base. A locking rod is fixed to the end face of the positioning screw, a limiting ring is slidably sleeved in the groove, a motor is fixed to the bottom surface of the cavity, a drive shaft is fixed to the output end of the motor, and a rotating block is fixed to the other end of the drive shaft.

[0004] Although the aforementioned patents can detect seat rings of various specifications, they suffer from poor adaptability, low detection accuracy, and low overall detection efficiency. In practical applications, they have the following main shortcomings:

[0005] 1. When switching between different sizes of seat rings for testing, the adaptive effect is poor. It is necessary to stop the operation of the testing machine first, and then manually find the corresponding inner diameter limiting ring according to the outer diameter of the seat ring and install it in the designated position of the testing machine before the testing can continue. This process takes a long time and seriously affects the testing efficiency.

[0006] 2. The gap between the inner diameter of the limiting ring and the outer diameter of the seat ring will affect the detection accuracy and may even lead to misjudgment of the boundary, thus affecting the accurate assessment of the seat ring quality;

[0007] 3. The testing process is mostly manual and involves complex steps, which not only increases the workload of operators but also makes the test results prone to deviation due to human factors. Utility Model Content

[0008] The purpose of this invention is to propose an adaptive multi-specification seat ring clamping mechanism, which has a simple structure, can adaptively clamp seat rings of different specifications, and has a good adaptive effect.

[0009] The technical solution adopted to achieve the purpose of this utility model is:

[0010] An adaptive multi-size seat ring clamping mechanism includes three or more adaptive sliders evenly distributed around the outer periphery of the seat ring, and an adjustment device disposed around the outer periphery of the adaptive sliders; the two sides of the adaptive sliders are in contact with the adjustment device and the seat ring respectively; the adjustment device adjusts the radial movement of the adaptive sliders to adaptively clamp seat rings of different sizes.

[0011] Furthermore, it also includes a base, a servo motor, and a rotary positioning sleeve; the base has an assembly hole, the servo motor is fixed to the bottom of the base, the lower part of the rotary positioning sleeve is embedded in the assembly hole and fixedly connected to the output shaft of the servo motor; the upper side wall of the rotary positioning sleeve has three or more evenly distributed placement holes.

[0012] The adjusting device is an adjusting nut. The upper part of the inner wall of the adjusting nut is a tapered adjusting part with a diameter that gradually decreases from top to bottom, and the lower part is a connecting part that is threadedly connected to the rotating positioning sleeve. The adaptive slider is located in the placement hole, with its two sides contacting the tapered adjusting part and the seat ring respectively. The side in contact with the tapered adjusting part is an adaptive inclined surface. The rotation of the rotating positioning sleeve drives the adjusting nut to move axially, thereby adjusting the radial movement of the adaptive slider so that it adaptively clamps seat rings of different specifications.

[0013] Furthermore, the movable surface of the slider has a movable groove along the radial direction of the rotary positioning sleeve, and an adaptive spring is installed in the movable groove. The adaptive spring is fixed to the rotary positioning sleeve by a limiting post. When the adjusting nut presses the adaptive slider, the adaptive spring is compressed. When the pressing is removed, the adaptive spring returns to its original position.

[0014] Furthermore, it also includes an anti-rotation guide pin, the lower end of which is fixed on the base. The adjusting nut has a guide hole that matches the anti-rotation guide pin. The rotating positioning sleeve rotates to drive the adjusting nut to move axially along the anti-rotation guide pin.

[0015] Furthermore, the outer periphery of the adjusting nut is also provided with a guide seat that matches the anti-rotation guide pin, and the guide hole is opened in the guide seat; there are two or more guide seats, and the number of anti-rotation guide pins matches the number of guide seats.

[0016] Furthermore, a limiting seat is provided on the outer periphery of the rotary positioning sleeve. The outer diameter of the limiting seat is larger than the inner diameter of the assembly hole, which is used to prevent the rotary positioning sleeve from coming out of the assembly hole.

[0017] Furthermore, the upper inner cavity of the rotating positioning sleeve is provided with a placement platform for placing the seat ring, and the placement platform is located below the placement hole.

[0018] Furthermore, the rotating positioning sleeve is fixed to the base by bearings.

[0019] Another objective of this invention is to propose an adaptive multi-specification seat ring runout detection device, which has good versatility and greatly improves detection accuracy.

[0020] Another technical solution adopted to achieve the purpose of this utility model is: an adaptive multi-specification seat ring bounce detection device, including the above-mentioned adaptive multi-specification seat ring clamping mechanism, and also including a rotary motor and a laser rangefinder sensor. The rotary motor is fixed on the base, and the laser rangefinder sensor is connected to the rotary motor through a connecting arm.

[0021] Another objective of this invention is to propose an adaptive multi-specification seat ring runout detection system, which is easy to operate, highly automated, and improves detection efficiency and accuracy.

[0022] The technical solution adopted to achieve another objective of this utility model is: an adaptive multi-specification seat ring bounce detection system, including the above-mentioned adaptive multi-specification seat ring bounce detection device, and also including a PLC controller, which controls the working state of the adaptive multi-specification seat ring bounce detection device.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. This utility model, through the cooperation of a servo motor, a rotating positioning sleeve, and an adjusting nut, can adaptively clamp seat rings of different specifications. It eliminates the need to design a special detection device or perform complex adjustment operations for each specification of seat ring, greatly improving the versatility and applicability of the device, reducing costs, and improving detection efficiency.

[0025] 2. This utility model can make the adaptive slider fit tightly against the seat ring by adjusting the nut, thereby reducing the gap between the seat ring and the adaptive slider, overcoming the problem of gap between the inner diameter of the traditional limiting ring and the outer diameter of the seat ring, and further improving the detection accuracy;

[0026] 3. The adaptive spring in this utility model enables the adaptive slider to change position more smoothly and gently when it is squeezed and unsqueezed by the adjusting nut; and when detecting different sizes of seat rings, even if the seat ring size changes significantly, the adaptive spring can help the adaptive slider adapt to the seat ring size better through its own elastic deformation and reset, further enhancing the device's adaptability to multiple sizes of seat rings.

[0027] 4. The anti-rotation guide pin of this utility model can effectively prevent the adjusting nut from rotating unnecessarily when the rotating positioning sleeve rotates, ensuring that the adjusting nut can only move linearly along a specific axial direction, thereby improving the operating accuracy and reliability of this utility model;

[0028] 5. The PLC controller of this utility model can automatically control the adaptive multi-specification seat ring runout detection device without frequent manual intervention in the detection process, which greatly improves the automation level of the detection work, reduces the errors and uncertainties caused by manual operation, and improves detection efficiency and accuracy.

Detailed Implementation

[0046] The illustrated embodiments are provided to better illustrate the present invention, but the content of the present invention is not limited to the illustrated embodiments. Therefore, non-essential improvements and adjustments made to the implementation schemes by those skilled in the art based on the above-described content of the present invention still fall within the protection scope of the present invention.

[0047] Example 1

[0048] like Figures 1 to 15 As shown, an adaptive multi-specification seat ring clamping mechanism includes three or more adaptive sliders 5 evenly distributed around the outer periphery of the seat ring 23, and an adjustment device disposed around the outer periphery of the adaptive sliders 5; the two sides of the adaptive sliders 5 are in contact with the adjustment device and the seat ring 23 respectively; the adjustment device adjusts the radial movement of the adaptive sliders 5 to adaptively clamp seat rings 23 of different specifications.

[0049] In this embodiment, it also includes a base 1, a servo motor 2, and a rotating positioning sleeve 3; the base 1 has an assembly hole 6, the servo motor 2 is fixed to the bottom of the base 1, the lower part of the rotating positioning sleeve 3 is embedded in the assembly hole 6, and is fixedly connected to the output shaft 7 of the servo motor 2; the upper side wall of the rotating positioning sleeve 3 has three or more evenly distributed placement holes 8.

[0050] The adjusting device is an adjusting nut 4. The upper part of the inner wall of the adjusting nut 4 is a conical adjusting part 9 with a diameter that gradually decreases from top to bottom, and the lower part is a connecting part 10 that is threadedly connected to the rotating positioning sleeve 3. The adaptive slider 5 is located in the placement hole 8, and its two sides are in contact with the conical adjusting part 9 and the seat ring 23 respectively. The side in contact with the conical adjusting part 9 is an adaptive inclined surface. The rotating positioning sleeve 3 rotates to drive the adjusting nut 4 to move axially, thereby adjusting the radial movement of the adaptive slider 5 so that it adaptively clamps the seat ring 23 of different specifications.

[0051] In this embodiment, the lower part of the adjusting nut 4 is threadedly connected to the rotating positioning sleeve 3 via the connecting part 10. When the rotating positioning sleeve 3 rotates, the adjusting nut 4 moves along the axial direction due to the characteristics of the threaded connection. The upper part of the inner wall of the adjusting nut 4 in this embodiment is a conical adjusting part 9. The adaptive slider 5 is disposed in the placement hole 8 on the upper part of the rotating positioning sleeve 3, with its two sides contacting the conical adjusting part 9 and the seat ring 23 respectively. The side contacting the conical adjusting part 9 is an adaptive inclined surface. When the adjusting nut 4 moves axially, its conical adjusting part 9 exerts a force on the adaptive inclined surface of the adaptive slider 5, which causes the adaptive slider 5 to move radially. In actual operation, by adjusting the axial movement of the nut 4, the radial movement of the adaptive slider 5 can be controlled, allowing the adaptive slider 5 to adaptively clamp seat rings 23 of different specifications.

[0052] The device in this embodiment can adaptively clamp different specifications of seat rings 23, eliminating the need for a separate detection device or complex adjustment operations for each specification of seat ring 23. This greatly improves the versatility and applicability of the device and reduces costs. The servo motor 2 drives the rotating positioning sleeve 3 to rotate, thereby precisely controlling the axial movement of the adjusting nut 4 and accurately adjusting the radial movement of the adaptive slider 5. This improves the accuracy of seat ring 23 runout detection. Simultaneously, adjusting the adjusting nut 4 ensures that the adaptive slider 5 fits tightly against the seat ring 23, reducing the gap between the seat ring 23 and the adaptive slider 5. This overcomes the problem of gaps between the inner diameter of the traditional limiting ring and the outer diameter of the seat ring 23, further improving detection accuracy.

[0053] like Figure 4 , Figure 6 , Figure 7 , Figures 13 to 15As shown, in this embodiment, the movable surface of the slider has a movable groove 11 along the radial direction of the rotary positioning sleeve 3. An adaptive spring 12 is installed within the movable groove 11, and the adaptive spring 12 is fixed to the rotary positioning sleeve 3 by a limiting post 13. When the adjusting nut 4 presses against the adaptive slider 5, the adaptive spring 12 is compressed; when the pressing is released, the adaptive spring 12 returns to its original position. This structure not only adaptively clamps seat rings 23 of different specifications but also reduces the gap between the seat ring 23 and the adaptive slider 5. In this invention, the rotary positioning sleeve 3 also has a fixing hole 26 for fixing the limiting post 13.

[0054] A movable groove 11 is formed on the movable surface of the slider along the radial direction of the rotating positioning sleeve 3, providing installation space for the adaptive spring 12. The adaptive spring 12 is fixed to the rotating positioning sleeve 3 by a limiting post 13, ensuring a stable installation position for the adaptive spring 12 during device operation and preventing it from moving arbitrarily, thus guaranteeing its normal function. When the adjusting nut 4 presses the adaptive slider 5, the adaptive slider 5 moves radially due to the force exerted by the conical adjusting part 9 of the adjusting nut 4. During this movement, the adaptive slider 5 compresses the adaptive spring 12 located in the movable groove 11. At this time, the adaptive spring 12 undergoes elastic deformation and stores elastic potential energy. When the pressing of the adjusting nut 4 on the adaptive slider 5 is removed, the elastic potential energy stored in the adaptive spring 12 is released, generating an elastic force opposite to that during pressing, pushing the adaptive slider 5 along the movable groove 11 back to its initial position, thus achieving reset. Based on this, the adaptive slider 5 in this embodiment can maintain a relatively stable position change under the action of the adaptive spring 12 under different working states, better adapting to the detection requirements of different specifications of seat rings 23.

[0055] In this embodiment, the adaptive spring 12 enables the adaptive slider 5 to change position more smoothly and gently when it is squeezed and unsqueezed by the adjusting nut 4. When detecting seat rings 23 of different specifications, even if the specifications of the seat rings 23 vary greatly, the adaptive spring 12 can help the adaptive slider 5 better adapt to the size of the seat rings 23 through its own elastic deformation and reset, further enhancing the device's adaptability to multiple specifications of seat rings 23.

[0056] like Figures 1 to 9 As shown, in this embodiment, a non-rotating guide pin 14 is also included, the lower end of which is fixed on the base 1. The adjusting nut 4 has a guide hole 15 that matches the non-rotating guide pin 14. The rotating positioning sleeve 3 rotates to drive the adjusting nut 4 to move axially along the non-rotating guide pin 14.

[0057] When the servo motor 2 drives the rotary positioning sleeve 3 to rotate, the adjusting nut 4 will normally tend to rotate along with the rotary positioning sleeve 3 due to the threaded connection between the adjusting nut 4 and the rotary positioning sleeve 3. However, because the anti-rotation guide pin 14 is fixed on the base 1 and passes through the guide hole 15 on the adjusting nut 4, the rotation of the adjusting nut 4 in the circumferential direction is restricted by the anti-rotation guide pin 14 and cannot rotate freely. The rotation of the rotary positioning sleeve 3 will be transmitted through the threaded drive, forcing the adjusting nut 4 to move linearly along the axis of the anti-rotation guide pin 14, thereby converting the rotational motion of the rotary positioning sleeve 3 into the linear motion of the adjusting nut 4, which in turn drives the adaptive slider 5 to move radially to clamp the seat ring 23. When it is necessary to remove the seat ring 23, the rotary positioning sleeve 3 rotates in the opposite direction, causing the linear motion of the adjusting nut 4 to move in the opposite direction, which in turn drives the adaptive slider 5 to move in the opposite direction to release the clamping of the seat ring 23, thereby removing the seat ring 23.

[0058] The anti-rotation guide pin 14 in this embodiment can effectively prevent the adjusting nut 4 from rotating unnecessarily when the rotating positioning sleeve 3 rotates. Through the cooperation between the anti-rotation guide pin 14 and the guide hole 15, a stable guide track is provided for the movement of the adjusting nut 4, reducing the shaking and offset of the adjusting nut 4 during the movement process. This helps to ensure good contact and locking effect between the adaptive slider 5 and the seat ring 23, improving the operation accuracy and reliability of this embodiment. It can also enhance the structural stability of the entire detection device, reduce the risk of failure and damage caused by unstable component movement, and extend the service life of the device.

[0059] like Figures 1 to 6 , Figure 8 and Figure 9 As shown, in this embodiment, the outer periphery of the adjusting nut 4 is also provided with a guide seat 16 that matches the anti-rotation guide pin 14, and the guide hole 15 is opened in the guide seat 16; the number of guide seats 16 is two or more, and the number of anti-rotation guide pins 14 matches the number of guide seats 16.

[0060] To prevent the anti-rotation guide pin 14 from damaging the internal structure of the adjusting nut 4, this embodiment uses guide seats 16 to isolate the anti-rotation guide pin 14 from the internal structure of the adjusting nut 4. By setting two or more guide seats 16 and matching anti-rotation guide pins 14, the movement of the adjusting nut 4 is restricted and guided from multiple directions. Compared with a single guide structure, the multi-directional guiding method of this embodiment can effectively reduce the shaking, offset, and torsion of the adjusting nut 4 during movement, making the linear movement of the adjusting nut 4 smoother and more accurate, thereby ensuring that the adaptive slider 5 can more stably clamp the seat ring 23, improving the reliability and accuracy of detection. In a preferred embodiment of this embodiment, the number of guide seats 16 is two.

[0061] like Figures 1 to 6, Figures 10 to 12 As shown, in this embodiment, a limiting seat 17 is also provided on the outer periphery of the rotating positioning sleeve 3. The outer diameter of the limiting seat 17 is larger than the inner diameter of the assembly hole 6, which is used to prevent the rotating positioning sleeve 3 from coming out of the assembly hole 6.

[0062] In this embodiment, the limiting seat 17 is an annular plate-shaped structure disposed on the outer periphery of the rotating positioning sleeve 3. It is integrally formed with the rotating positioning sleeve 3. Due to the difference in outer diameter, the limiting seat 17 cannot enter the assembly hole 6. The limiting seat 17 effectively prevents the rotating positioning sleeve 3 from coming out of the assembly hole 6, ensuring the stability of the fit between the rotating positioning sleeve 3, the output shaft 7 of the servo motor 2, and the base 1. This makes the structure of the entire detection device more robust and reliable, reducing the risk of device failure and damage caused by component detachment.

[0063] In this embodiment, the guide seat 16 has an internal thread at its lower part, and the limit seat 17 has an external thread on its outer periphery. The guide seat 16 and the limit seat 17 are threaded together, which can further improve the transmission efficiency of the rotating positioning sleeve 3 to the adjusting nut 4.

[0064] In this embodiment, the adjusting nut 4 is also provided with a plunger through hole 24, and a spring plunger 25 is fixed inside the plunger through hole 24, with the bottom of the spring plunger 25 abutting against the upper surface of the limiting seat 17. The spring plunger 25 is only assembled in the adjusting nut 4, with the plunger head contacting the upper surface of the limiting seat 17. The elastic force of the plunger eliminates the gap between the rotating positioning sleeve 3 and the threaded connection of the adjusting nut 4, ensuring full contact of the thread profile surfaces. Specifically, after the spring plunger 25 is assembled in the adjusting nut 4, the spring inside it is in a certain compressed state, generating elastic force. The elastic force of the spring plunger 25 is transmitted to the upper surface of the limiting seat 17 through the bottom plunger head. Due to the interaction of forces, the limiting seat 17 will generate a reaction force on the spring plunger 25. The reaction force of the limiting seat 17 will cause the adjusting nut 4 to have a slight displacement tendency in the threaded connection direction, causing the thread profile surfaces of the rotating positioning sleeve 3 and the adjusting nut 4 to squeeze against each other, thereby eliminating the gap between them and ensuring full contact of the thread profile surfaces. The plunger head only contacts the upper surface of the limiting seat 17. This surface contact method ensures uniform force transmission and avoids damage to components due to excessive local force. In this embodiment, there are more than two plunger holes, which are evenly distributed on the adjusting nut 4, and the number of spring plungers 25 corresponds to the number of plunger holes.

[0065] like Figure 10 and Figure 11As shown, in this invention, the upper inner cavity of the rotating positioning sleeve 3 is provided with a placement platform 21 for placing the seat ring 23, and the placement platform 21 is located below the placement hole 8. When performing a runout test on the seat ring 23, the seat ring 23 is placed into the upper inner cavity of the rotating positioning sleeve 3 through the placement hole 8, and the seat ring 23 will naturally fall onto the placement platform 21. The placement platform 21 provides a stable and horizontal support surface for the seat ring 23, enabling the seat ring 23 to be accurately positioned within the rotating positioning sleeve 3.

[0066] like Figure 4 and Figure 6 As shown, in this invention, the rotating positioning sleeve 3 is fixed to the base 1 by a bearing 22. The inner ring of the bearing 22 is tightly fitted with the rotating positioning sleeve 3 and rotates with it, while the outer ring is fixed to the base 1, remaining relatively stationary. By using the bearing 22, the sliding friction between the rotating positioning sleeve 3 and the base 1 is converted into rolling friction, significantly reducing friction and greatly minimizing wear between them.

[0067] Example 2

[0068] This embodiment provides an adaptive multi-specification seat ring bounce detection device. Compared with Embodiment 1, the main difference in this embodiment is the addition of a rotary motor 18 and a laser rangefinder sensor 19.

[0069] like Figures 1 to 4 As shown, an adaptive multi-size seat ring detection device includes the adaptive multi-size seat ring clamping device of Embodiment 1; it also includes a corner motor 18 and a laser rangefinder 19. The corner motor 18 is fixed on the base 1, and the laser rangefinder 19 is connected to the corner motor 18 through a connecting arm 20.

[0070] In this embodiment, the angle motor 18 starts working after receiving an external control signal, and its output shaft 7 rotates according to a set angle and direction. Since the laser rangefinder 19 is connected to the output shaft 7 of the angle motor 18 via the connecting arm 20, when the angle motor 18 rotates, it drives the connecting arm 20 and the laser rangefinder 19 to perform a circular motion around the output shaft 7 of the angle motor 18. During the runout detection process of the seat ring 23, the rotating positioning sleeve 3 does not rotate, and the laser rangefinder 19 continuously emits a laser beam. When the laser beam irradiates the surface of the seat ring 23, it is reflected. The sensor receives the reflected laser and calculates the distance between itself and the surface of the seat ring 23 based on the time difference between the laser emission and reception. As the angle motor 18 drives the sensor to rotate continuously, the sensor can measure the distance between itself and different positions on the surface of the seat ring 23, thereby obtaining distance data for multiple points on the surface of the seat ring 23, thus detecting whether there are any unevenness or irregularities on the surface of the seat ring 23, and achieving runout detection.

[0071] In this embodiment, the angle motor 18 drives the laser rangefinder 19 to rotate, enabling the sensor to measure distance information at different angles and positions on the surface of the seat ring 23. Compared to fixed-position measurement methods, this rotatable measurement system can acquire more comprehensive surface data of the seat ring 23, more accurately reflecting the overall shape of the seat ring 23, and improving the comprehensiveness and accuracy of the detection. Furthermore, the angle motor 18 and the laser rangefinder 19 can be integrated with an external control system to achieve automated measurement. The control system can precisely control the rotation of the angle motor 18 and the measurement operation of the laser rangefinder 19 according to a preset program, eliminating the need for manual adjustment of the measurement position, reducing the impact of human factors on the detection results, and improving the automation level and reliability of the detection.

[0072] Example 3

[0073] This embodiment provides an adaptive multi-specification seat ring bounce detection system. Compared with embodiment 2, the main difference in this embodiment is the addition of a PLC controller.

[0074] This embodiment provides an adaptive multi-size seat ring bounce detection system, including the adaptive multi-size seat ring bounce detection device of embodiment 2, and also includes a PLC controller, which controls the working state of the adaptive multi-size seat ring bounce detection device.

[0075] The adaptive multi-specification seat ring runout detection system of this embodiment consists of an adaptive multi-specification seat ring runout detection device and a PLC controller. The PLC controller is electrically connected to the servo motor 2, the rotary motor 18, and the laser rangefinder 19. During the detection process, the laser rangefinder 19 in the detection device collects relevant data of the seat ring 23 in real time, such as the distance information between different positions on the surface of the seat ring 23 and the sensor, and transmits this data to the PLC controller in the form of electrical signals. After receiving these signals, the PLC controller analyzes and processes the data according to the pre-written control program. Specifically, by connecting and mounting the high-precision laser rangefinder 19 above the seat ring 23 with a rotary cylinder, its beam is directed to the position of the seat ring 23 to be measured. Through the sensor signal transmission and power line connection to the display terminal and PLC, automatic acquisition and storage of measurement data and automated program control of the measurement cycle can be realized. In addition, the PLC controller can also adjust various parameters of the detection device according to the specification information of the seat ring 23, so that the detection device can adapt to the detection requirements of seat rings 23 of different specifications. The PLC controller in this embodiment can automatically control the adaptive multi-specification seat ring runout detection device without frequent manual intervention in the detection process, which greatly improves the automation level of the detection work, reduces the errors and uncertainties caused by manual operation, and improves detection efficiency and accuracy.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
