Description

Technical Field

[0001] The present invention relates to the technical field of load cells, and particularly to a flexible hinge module, a processing auxiliary device and method for the flexible hinge module. Background Art

[0002] The flexible hinge module is a key component of a precision balance. Through the action of multiple flexible hinges on the module, minute displacements are precisely converted into recognizable signals. This sensor module is not only used for high-precision weighing, but also has many applications in high-sensitivity vibration sensing, disaster monitoring, and the military field.

[0003] The key factors affecting the mechanical properties of the flexible hinge module are the multiple flexible hinges on the module. A flexible hinge is a typical thin-wall structure. To meet the usage requirements, strict requirements are imposed on the surface quality of the thin-wall part and the shape dimensions of the arc (for a straight-beam flexible hinge, the arc is part or all of the groove). The thickness at the thinnest part is often only about 0.1 mm, and a high consistency requirement for the thickness of each hinge is also required.

[0004] The flexible hinge module generally uses aluminum alloy material, and its strength is not high. The processing of flexible hinges involves multiple processes, including milling, wire cutting, electrical discharge machining, grinding, and polishing. In traditional processing technologies, due to the special structure, during the processing, affected by processing stress and deformation, the hinges are extremely prone to breakage, the yield rate is not high, and the overall processing difficulty is very great. Different from traditional processing technologies, currently, the method of electrical discharge machining with rocking is adopted. Although the machining cutting force is small and the shape at the hinge can be better guaranteed, wire cutting has a high machining accuracy and can well meet the dimensional requirements. However, electrical discharge machining and wire cutting will inevitably form a metamorphic layer and microscopic defects on the machining surface, affecting the strength and fatigue life of the parts. Moreover, wire cutting can only machine through structures and cannot machine the hinge structures at non-through parts. When milling is used, since the remaining thickness at the hinge is too small, the workpiece is prone to deformation and even breakage, and the yield rate is not high.

[0005] Aiming at the processing problems of the flexible hinge module, designing a flexible hinge processing technology that can ensure the product qualification rate is a technical problem urgently to be solved by those skilled in the art. Summary of the Invention

[0006] Aiming at the above-mentioned processing problems of the flexible hinge module, designing a flexible hinge processing technology that can ensure the product qualification rate is a technical problem urgently to be solved by those skilled in the art. The present invention provides a flexible hinge module, a processing auxiliary device and method for the flexible hinge module. The structural design of the flexible hinge module, the structural design of the auxiliary tool, and the corresponding processing method provided by this solution can effectively improve the product qualification rate of the flexible hinge module processing.

[0007] In view of the above problems, the flexible hinge module, the processing auxiliary device and method for the flexible hinge module provided by the present invention solve the problems through the following technical key points: The flexible hinge module is a straight-beam flexible hinge. The flexible hinge module includes a plurality of module seats and unit hinges connected in series between the module seats. The module seats include a first module seat and a second module seat. Connection units are provided on both the first module seat and the second module seat. The connection unit is used to realize the rigid connection between the first module seat and the second module seat, and the rigid connection is a detachable connection.

[0008] In the prior art, for the processing of the unit hinges on the straight-beam flexible hinge module, generally, after the forming processing of the rest of the part is completed, the groove processing is carried out. That is, at this time, the processing of the module seat and the processing of the straight beam on the unit hinge are completed, and only two grooves need to be processed at both ends of the straight beam respectively to obtain a complete unit hinge. The above groove processing is generally regarded as the finishing process in the processing of the flexible hinge module. Although there are various processes for completing the groove processing in the prior art, such as milling, wire cutting, electric discharge machining, grinding and polishing, etc., and among these processing processes, although wire cutting and electric discharge machining can solve the problem of processing accuracy, it is inevitable to form a metamorphic layer and microscopic defects on the groove surface, which affect the strength and fatigue life of the module, and the use of wire cutting has certain limitations; when using milling, grinding, etc. for processing, due to the too small remaining thickness at the hinge, the workpiece is prone to deformation and even fracture. Due to the structural characteristics of the flexible hinge module itself, the qualified rate of the finished products of the existing flexible hinge modules is not high.

[0009] In this solution, according to the specific structure of the flexible hinge module, it can be understood that the first module seat and the second module seat are respectively the module seats at the ends of the flexible hinge module, such as in the case where the flexible hinge module itself includes two module seats; it can also be understood as the module seats between the unit hinges, such as including three module seats. Among the above first module seat and second module seat, one of them is connected in series in the middle of the other two module seats.

[0010] In this solution, it is set that connection units are provided on both the first module base and the second module base. The connection units are used to achieve a rigid connection between the first module base and the second module base. In this way, when machining the groove on the hinge of the machining unit, a connection bar serving as a constraint for the straight beam can be first set between the straight beam and the module base. After machining the groove by machining methods such as milling and grinding, the connection unit is used to make the first module base and the second module base form a rigid connection relationship, and then the connection bar is removed by means such as shearing. In the above process, since the relative positions of the straight beam and the module base can be constrained by the connection bar, when machining the groove, by reducing the deformation of the groove position, higher machining accuracy of the groove position can be obtained by using traditional machining methods such as milling and grinding, which is beneficial to the machining quality of the unit hinge. When removing the connection bar after machining the groove, since the relative positions of the first module base and the second module base are constrained by the connection unit such as in cooperation with the fixing plate at this time, during the process of removing the connection bar, the groove position will not be subjected to sudden stress, so as to avoid damage to the weak part of the groove position on the unit hinge. When removing the connection of the fixing plate on the flexible hinge module, since the moment when the connection between the fixing plate and any module base fails is predictable compared with the breakage of the connection bar, at this time, a constraint is applied between the first module base and the second module base when their rigid connection fails. The above constraint is used to constrain the change of their positions, and then by slowly releasing the constraint, the groove position is prevented from being subjected to sudden stress, so as to avoid damage to the weak part of the groove position on the unit hinge, and finally the purpose of improving the qualified rate of the flexible hinge module products is achieved.

[0011] In summary, the structural design of the flexible hinge module provided by this solution is beneficial to improving the machining qualified rate of the flexible hinge module products.

[0012] As a further technical solution of the flexible hinge module:

[0013] As a form of connection unit implementation with reliable connection, convenient connection completion and connection removal, the connection units are all screw holes provided on the corresponding module bases. That is, for example, the above rigid connection is achieved by using a connecting plate, and through the screw holes, the connecting plate and each module base form a screw connection relationship.

[0014] To form better position stability between the first module base and the second module base through the screw holes, it is set that on a pair of opposite sides of the flexible hinge module, unit hinges are provided on each side; screw holes are provided on the first module base and the second module base on each side of the opposite side. The purpose of this solution is to achieve better anti-rotation constraint of the module base when removing the connection bar.

[0015] To achieve better positional stability between the first module seat and the second module seat through the screw holes, it is set that: among the first module seat and the second module seat, the number of screw holes on each is multiple. This solution aims to achieve better anti-overturning restraint of the module seat when removing the connecting strip. As those skilled in the art, the directions of anti-overturning restraint achieved by the above two anti-overturning restraints are different: the solution with screw holes on each side of the opposite sides aims to achieve mutual restraint on both sides of the module seat, and the fact that the number of screw holes on each is multiple aims to prevent rotation through shear of the screws.

[0016] This solution also discloses a flexible hinge module processing auxiliary device, including a fixing plate, which is used for any one of the above flexible hinge modules to achieve rigid connection between the first module seat and the second module seat through the connecting unit. In summary, the flexible hinge module processing auxiliary device provided by this solution is applied to the flexible hinge module with the above structural form, which can effectively improve the product qualification rate of flexible hinge module processing.

[0017] As a further technical solution of the flexible hinge module processing auxiliary device:

[0018] The connecting units are all screw holes provided on the corresponding module seats;

[0019] Among the first module seat and the second module seat, the number of screw holes on each is multiple;

[0020] The fixing plate is screw-connected to each screw hole, and the number of screw holes on the fixing plate matches the number of screw holes on the module seat. This solution provides a fixing plate solution that is beneficial to the relative position accuracy of the first module seat and the second module seat through shear of the screws.

[0021] As a technical solution that can restrain the straight beam from moving towards the outside of the flexible hinge module through the fixing plate, on a pair of opposite sides of the flexible hinge module, unit hinges are provided on each side; screw holes are provided on the first module seat and the second module seat on each side of the opposite sides;

[0022] The number of the fixing plates is two;

[0023] The unit hinge includes a straight beam and a groove provided at the end of the straight beam. One fixing plate is screw-connected to each side. After the fixing plate is screw-connected to the module seat, the inner side of each fixing plate is in contact with the outer side of the straight beam on this side of the flexible hinge module.

[0024] Meanwhile, this solution also discloses a flexible hinge module processing method, which is used for the processing of any one of the above flexible hinge modules, and before processing the unit hinge, a connecting strip is provided between the straight beam of the unit hinge and the module seat. One end of the connecting strip is fixedly connected to the straight beam, and the other end of the connecting strip is fixedly connected to the module seat;

[0025] After the connection bar is set, the machining of the groove on the unit hinge is completed;

[0026] After the groove machining is completed, the rigid connection between the first module seat and the second module seat is realized by connecting the fixed plate to the connection unit;

[0027] After the rigid connection is completed, the connection bar is removed. As described above, adopting this solution, before machining the groove, the connection bar is used to reduce the force at the groove position. Before removing the connection bar, the relative positions of the first module seat and the second module seat are constrained by the fixed plate. Then, after the rigid connection is formed on the fixed plate, the connection bar is removed. Then, by using the predictable failure of the rigid connection, a resistance to restrict the relative movement of the first module seat and the second module seat is applied, and then by slowly releasing the resistance, the unit hinge is protected, and finally the purpose of improving the qualified rate of the flexible hinge module product is achieved.

[0028] As a further technical solution of the flexible hinge module processing method, specifically, before machining the groove, all other parts of the flexible hinge module are formed to obtain a flexible hinge module blank;

[0029] The connection bar is a reinforcing rib reserved on the flexible hinge module blank during the forming process;

[0030] Before machining the groove, the flexible hinge module blank is aged.

[0031] As a further technical solution of the flexible hinge module processing method, after the groove machining, the connection of the fixed plate and the removal of the connection bar are completed, the combination of the flexible hinge module and the fixed plate is annealed. As those skilled in the art, the above annealing and aging treatments are both to remove internal stress to facilitate the final product quality.

[0032] The present invention has the following beneficial effects:

[0033] In this solution, it is set that connection units are provided on both the first module base and the second module base. The connection units are used to achieve a rigid connection between the first module base and the second module base. In this way, when machining the groove on the hinge of the machining unit, a connecting bar serving as a constraint for the straight beam can be first arranged between the straight beam and the module base. After machining the groove through machining methods such as milling and grinding, the above connection units are used to make the first module base and the second module base form a rigid connection relationship, and then the connecting bar is removed by means such as shearing. In the above process, since the relative position of the straight beam and the module base can be restricted by the connecting bar, when machining the groove, by reducing the deformation of the groove position, higher machining accuracy of the groove position can be obtained by using traditional machining methods such as milling and grinding, which is beneficial to the machining quality of the unit hinge. When removing the connecting bar after the groove machining is completed, since the relative position of the first module base and the second module base is restricted by the connection unit such as in cooperation with the fixing plate at this time, during the process of removing the connecting bar, the groove position will not be subjected to sudden stress, so as to avoid damage to the weak part of the groove position on the unit hinge. When removing the connection of the fixing plate on the flexible hinge module, since the moment when the connection between the fixing plate and any module base fails is predictable compared with the breakage of the connecting bar. At this time, when the rigid connection between the first module base and the second module base fails, a constraint is applied between the two. The above constraint is used to restrict the change of their positions, and then by slowly releasing the constraint, the groove position is prevented from being subjected to sudden stress, so as to avoid damage to the weak part of the groove position on the unit hinge, and finally the purpose of improving the qualified rate of the flexible hinge module products is achieved.

[0034] The above structural design, auxiliary device and processing method of the flexible hinge module correspond to each other, and all aim to improve the qualified rate of the flexible hinge module products. Description of the Drawings

[0039] The present invention will be further described in detail below in conjunction with embodiments, but the present invention is not limited to the following embodiments:

[0040] Embodiment 1:

[0041] As Figures 1 to 3 shown, a flexible hinge module, the flexible hinge module is a straight beam 31 type flexible hinge, the flexible hinge module includes a plurality of module seats and unit hinges 3 connected in series between the module seats, the module seats include a first module seat 1 and a second module seat 2, and connection units are provided on both the first module seat 1 and the second module seat 2, and the connection units are used to realize the rigid connection between the first module seat 1 and the second module seat 2, and the rigid connection is a detachable connection.

[0042] In the prior art, for the processing of the unit hinge 3 on the straight beam 31 type flexible hinge module, generally, after the forming processing of the rest part is completed, the groove 32 is processed. That is, at this time, the processing of the module seat and the processing of the straight beam 31 on the unit hinge 3 are completed, and only two grooves 32 need to be processed at both ends of the straight beam 31 respectively to obtain a complete unit hinge 3. The above processing of the groove 32 is generally regarded as the finishing process in the processing of the flexible hinge module. Although there are various processes for completing the processing of the groove 32 in the prior art, such as milling, wire cutting, electric discharge machining, grinding and polishing, etc., and among these processing processes, although wire cutting and electric discharge machining can solve the problem of processing accuracy, it is inevitable to form a metamorphic layer and micro defects on the surface of the groove 32, which affects the strength and fatigue life of the module, and the use of wire cutting has certain limitations; when using milling, grinding, etc. for processing, due to the too small remaining thickness at the hinge, the workpiece is prone to deformation and even fracture. The above is due to the structural characteristics of the flexible hinge module itself, resulting in a low qualified rate of the finished flexible hinge module.

[0043] In this solution, according to the specific structure of the flexible hinge module, it can be understood that the first module seat 1 and the second module seat 2 are respectively the module seats at the ends of the flexible hinge module, such as the case where the flexible hinge module itself includes two module seats; it can also be understood as the module seats between the unit hinges 3, such as including three module seats. Among the above first module seat 1 and second module seat 2, one of them is connected in series in the middle of the other two module seats.

[0044] In this solution, it is set that connection units are provided on both the first module base 1 and the second module base 2. The connection unit is used to achieve a rigid connection between the first module base 1 and the second module base 2. In this way, when machining the groove 32 on the machining unit hinge 3, a connecting strip 5 serving as a constraint member for the straight beam 31 can be first arranged between the straight beam 31 and the module base. After machining the groove 32 by machining methods such as milling and grinding, the first module base 1 and the second module base 2 form a rigid connection relationship through the above connection unit, and then the connecting strip 5 is removed by means such as shearing. In the above process, since the relative position of the straight beam 31 and the module base can be constrained by the connecting strip 5, when machining the groove 32, by reducing the deformation of the position of the groove 32, higher machining accuracy of the position of the groove 32 can be obtained by using traditional milling and grinding machining methods, which is beneficial to the machining quality of the unit hinge 3. When removing the connecting strip 5 after machining the groove 32, since the relative position of the first module base 1 and the second module base 2 is constrained by the connection unit such as in cooperation with the fixing plate 6 at this time, during the process of removing the connecting strip 5, the position of the groove 32 will not be subjected to sudden stress, so as to avoid damage to the weak part of the position of the groove 32 on the unit hinge 3. When removing the connection of the fixing plate 6 on the flexible hinge module, since the moment when the connection between the fixing plate 6 and any module base fails is predictable compared with the fracture of the connecting strip 5, at this time, when the rigid connection between the first module base 1 and the second module base 2 fails, a constraint is applied between the two to constrain the change of their positions, and then by slowly releasing the constraint, the position of the groove 32 is prevented from being subjected to sudden stress, so as to avoid damage to the weak part of the position of the groove 32 on the unit hinge 3, and finally the purpose of improving the qualified rate of the flexible hinge module product is achieved.

[0045] In summary, the structural design of the flexible hinge module provided by this solution is beneficial to improving the machining qualified rate of the flexible hinge module product.

[0046] Embodiment 2:

[0047] This embodiment makes further limitations on the basis of Embodiment 1. As Figures 1 to 3 shown, as a form of realizing the connection unit with reliable connection, convenient connection and removal of connection, the connection units are all screw holes 4 provided on the corresponding module bases. That is, if the above rigid connection is realized by using a connecting plate, through the screw holes 4, the connecting plate and each module base form a screw connection relationship.

[0048] To achieve better position stability of the first module base 1 and the second module base 2 through the screw holes 4, it is set that on a pair of opposite sides of the flexible hinge module, unit hinges 3 are provided on each side; screw holes 4 are provided on the first module base 1 and the second module base 2 on each side of the opposite sides. The purpose of this solution is to achieve better anti-tilting constraint of the module base when removing the connecting strip 5.

[0049] To achieve better positional stability between the first module base 1 and the second module base 2 through the screw holes 4, it is set that: among the first module base 1 and the second module base 2, the number of screw holes 4 on each is multiple. This solution aims to achieve better anti-rotation restraint of the module base when removing the connecting bar 5. As those skilled in the art, the rotation directions achieved by the above two anti-rotation restraints are different: the solution with screw holes 4 on each of the opposite sides aims to achieve mutual restraint on both sides of the module base, and the fact that the number of screw holes 4 on each is multiple aims to prevent rotation by shear of the screws.

[0050] Embodiment 3:

[0051] This embodiment further limits on the basis of Embodiment 1 or Embodiment 2. This embodiment discloses a flexible hinge module processing auxiliary device, including a fixing plate 6, and the fixing plate 6 is used for the flexible hinge module described in any one of the above, so as to achieve rigid connection between the first module base 1 and the second module base 2 through the connection unit. To sum up, the flexible hinge module processing auxiliary device provided by this solution is applied to the flexible hinge module with the above structural form, and can effectively improve the product qualification rate of flexible hinge module processing.

[0052] As a further technical solution of the flexible hinge module processing auxiliary device:

[0053] The connection units are all screw holes 4 provided on the corresponding module bases;

[0054] Among the first module base 1 and the second module base 2, the number of screw holes 4 on each is multiple;

[0055] The fixing plate 6 is screw-connected to each screw hole 4, and the number of screw holes 4 on the fixing plate 6 matches the number of screw holes 4 on the module base. This solution provides a fixing plate 6 scheme that is beneficial to the relative position accuracy of the first module base 1 and the second module base 2 by shear of the screws.

[0056] As a technical solution that can restrain the straight beam 31 from moving towards the outside of the flexible hinge module through the fixing plate 6, on a pair of opposite sides of the flexible hinge module, unit hinges 3 are provided on each side; screw holes 4 are provided on the first module base 1 and the second module base 2 on each of the opposite sides;

[0057] The number of the fixing plates 6 is two;

[0058] The unit hinge 3 includes a straight beam 31 and a groove 32 provided at the end of the straight beam 31. One fixing plate 6 is screw-connected to each side. After the fixing plate 6 is screw-connected to the module base, the inner side of each fixing plate 6 is in contact with the outer side of the straight beam 31 on this side of the flexible hinge module.

[0059] Example 4:

[0060] This embodiment further limits on the basis of any one of the technical solutions provided in Embodiment 1 or 2. This embodiment discloses a processing method for a flexible hinge module, which is used for processing the flexible hinge module described above. Before processing the unit hinge 3, a connecting strip 5 is arranged between the straight beam 31 of the unit hinge 3 and the module seat. One end of the connecting strip 5 is fixedly connected to the straight beam 31, and the other end of the connecting strip 5 is fixedly connected to the module seat.

[0061] After the connecting strip 5 is arranged, the processing of the groove 32 on the unit hinge 3 is completed.

[0062] After the processing of the groove 32 is completed, the rigid connection between the first module seat 1 and the second module seat 2 is realized by connecting the fixing plate 6 on the connecting unit.

[0063] After the rigid connection is completed, the connecting strip 5 is removed. As described above, adopting this solution, before processing the groove 32, the connecting strip 5 is used to reduce the force at the position of the groove 32. Before removing the connecting strip 5, the relative positions of the first module seat 1 and the second module seat 2 are restricted by the fixing plate 6. Then, after the connecting strip 5 is removed under the condition that the rigid connection is formed by the fixing plate 6, by using the way that the failure of the rigid connection can be predicted, a resistance to restrict the relative movement of the first module seat 1 and the second module seat 2 is applied, and then by slowly releasing the resistance, the unit hinge 3 is protected, and finally the purpose of improving the qualified rate of the flexible hinge module product is achieved.

[0064] As a further technical solution of the processing method for the flexible hinge module, specifically, before processing the groove 32, the forming processing of all other parts of the flexible hinge module is completed to obtain a flexible hinge module blank.

[0065] The connecting strip 5 is a reinforcing rib reserved on the flexible hinge module blank during the forming processing.

[0066] Before processing the groove 32, the flexible hinge module blank is subjected to aging treatment.

[0067] As a further technical solution of the processing method for the flexible hinge module, after the processing of the groove 32, the connection of the fixing plate 6 and the removal of the connecting strip 5 are completed, the combination of the flexible hinge module and the fixing plate 6 is annealed. As those skilled in the art, the above annealing and aging treatments are both to remove internal stress to facilitate the final product quality.

[0068] Example 5:

[0069] This embodiment provides a specific example based on this solution:

[0070] This embodiment is for machining the flexible hinge module of the unit hinge 3 with a thickness of 0.08 mm at the position of the groove 32.

[0071] The material of the flexible hinge module is 2A12. After roughing and semi-finishing, the forming machining is completed at all positions except the position of the groove 32, and the material is reserved as the connecting strip 5 between the straight beam 31 and the module seat. Then, artificial aging is carried out for 24 hours in a static state, and then 12 grooves 32 on the unit hinge 3 of the flexible hinge module are finish-machined. After installing the fixing plate 6, stress relief annealing is carried out, and finally the connecting strip 5 is removed. Then, the connection of the fixing plate 6 on the module seat is removed, and during the removal process, when the connecting strip 5 is disconnected from the module seat, a resistance is applied to restrict the relative displacement between the first module seat 1 and the second module seat 2, so that when the connection relationship is disconnected, the first module seat 1 and the second module seat 2 cannot freely generate relative displacement. By this method, the thickness of the thinnest part of the finally machined unit hinge 3 is only 0.08 mm, and the thickness consistency of the 12 groove 32 positions is ≤ 0.005 mm.

[0072] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific embodiments of the present invention are only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, other embodiments obtained without departing from the technical solution of the present invention should all be included within the protection scope of the present invention.
