Description

Technical Field

[0001] This invention relates to the field of orthopedic components, specifically an orthopedic device for irregularly shaped parts. Background Technology

[0002] A leveling machine utilizes the "Bauschinger effect" of materials to repeatedly bend sheet metal, gradually reducing bending deflection and transforming various original curvatures into a single curvature, thus leveling the sheet to achieve the required flatness precision. For sheet metal structures, leveling machines are described in patents such as Chinese Patent Publication No. CN113027854B (titled "A Roller Leveling Machine") and Chinese Patent Publication No. CN116637960B (titled "A Steel Plate Leveling Machine").

[0003] Leveling machines are highly effective in straightening flat sheet metal. However, for irregularly shaped parts with uneven surfaces, such as battery cases, where some structures are welded to the case using friction stir welding, the case undergoes localized deformation due to heat input. Clearly, these irregularly shaped parts cannot be straightened using leveling machines. Currently, straightening such parts mostly relies on cumbersome manual straightening methods or the expensive purchase of new straightening equipment. Both methods have shortcomings. Therefore, how to achieve efficient and low-cost straightening of irregularly shaped parts using traditional leveling machines is a pressing issue. Summary of the Invention

[0004] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides a device for straightening irregular parts, which not only retains the original straightening function of the plate in the leveling machine, but also realizes the straightening of irregular parts.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A device for straightening irregularly shaped parts includes a leveling machine and a straightening fixture for wrapping the box panel parts and feeding them into the rollers of the leveling machine to straighten them; wherein:

[0007] The orthopedic fixture includes an upper base plate and a lower base plate that are parallel to each other and fixed together by a fixing buckle. The box panel part is positioned and clamped between the upper base plate and the lower base plate. An upper or lower corrective slide is slidably passed through the upper base plate and the lower base plate respectively in the vertical direction. When the outer ends of the upper or lower corrective slide are pressed, the inner ends of the upper or lower corrective slide slide slide inward to a set limit position to squeeze the deformed part of the box panel part, thereby correcting it to a standard state.

[0008] As a further aspect of the present invention: both the upper and lower corrective sliders are axial structures with their axes distributed along the vertical direction. The outer ends of both the upper and lower corrective sliders can be detachably fixed with pressure heads, and the inner ends of the pressure heads abut against the upper or lower substrate, thereby positioning the upper or lower corrective sliders at the set limit positions.

[0009] As a further embodiment of the present invention: the upper and lower corrective slides are each fitted with a central guide sleeve that is fixed to the lower surface of the upper substrate and the upper surface of the lower substrate, respectively; the upper and lower corrective slides are each fitted with a return spring that compresses them to generate an outward sliding action; and the upper and lower corrective slides are each fitted with a protrusion on their shafts to position their outer ends.

[0010] As a further embodiment of the present invention: an extended guide sleeve is fitted on the rod near the inner end of the lower correction slide and is fixedly connected to the lower base plate.

[0011] As a further aspect of the present invention: from a top-down view, both the upper and lower corrective slides are arranged in a matrix of several pieces, and along the direction of movement of the orthopedic fixture within the corrective machine, the spacing between the axes of adjacent upper corrective slides and the spacing between the axes of adjacent lower corrective slides are both 45mm. The upper and lower corrective slides correspond one-to-one with each other or are horizontally offset by 22.5mm. Furthermore, the outer ends of all upper corrective slides are flush, and the outer ends of all lower corrective slides are flush.

[0012] As a further embodiment of the present invention: at least one product guide post is arranged on the top surface of the lower substrate at each side of the box panel part, and all the product guide posts enclose a guide cavity for sliding and guiding the box panel part in the vertical direction. A product clamping assembly is fixed on the upper substrate and the lower substrate to prevent the box panel part from moving vertically.

[0013] As a further embodiment of the present invention: the product clamping assembly includes a lower corner clamping block and a lower internal clamping block fixed on the lower substrate, and the product clamping assembly also includes an upper corner clamping block and an upper internal clamping block fixed on the upper substrate. The lower corner clamping block and the upper corner clamping block are each arranged in four groups distributed at the corners of the box panel parts to clamp the four corners of the box panel parts; the lower internal clamping block and the upper internal clamping block are arranged in several groups that correspond one-to-one and are distributed in the middle of the box panel parts to clamp the middle of the box panel parts.

[0014] As a further embodiment of the present invention: the top surface of the lower substrate is fixed with a positioning pin that engages with an existing shaped hole on the box plate part.

[0015] As a further aspect of the present invention: at least one substrate positioning post is fixedly connected to each of the four top sides of the lower substrate to position the distance between the lower substrate and the upper substrate.

[0016] As a further embodiment of the present invention: a substrate guide assembly for positioning and assembling each other is provided between the upper substrate and the lower substrate. The substrate guide assembly includes a substrate guide post fixed on the top surface of the lower substrate and a substrate guide sleeve disposed on the upper substrate and inserted into the substrate guide post.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By clamping the box panel parts in the straightening fixture, and feeding the straightening fixture into a traditional leveling machine, the upper and lower rollers in the leveling machine press the outer ends of the upper and lower straightening slides inward respectively. After the outer ends of the upper and lower straightening slides are pressed, the inner ends of the upper and lower straightening slides slide inward to the set limit position. By using the upper and lower straightening slides to slide inward and collide with the box panel parts and press the deformed parts of the box panel parts, the deformed parts of the box panel parts are straightened to the standard state. This achieves efficient and low-cost straightening of irregular parts in a traditional leveling machine.

[0019] 2. Both the outer ends of the upper and lower straightening slides are detachably fixed with pressure heads. The inner end of the pressure head abuts against the upper or lower base plate, thereby positioning the upper or lower straightening slide at its set limit position. In actual implementation, by changing pressure heads of different shapes, the set limit position of the upper or lower straightening slide can be adjusted according to different needs.

[0020] 3. In the non-working state, both the upper and lower straightening slides tend to slide outwards under the action of the return spring, causing them to initially separate from the box panel parts. Therefore, during the straightening process, the upper and lower straightening slides are first squeezed and pushed to impact the box panel parts, and then squeeze the box panel parts for straightening. This allows the upper and lower straightening slides to perform a straightening action similar to continuous hammering as the straightening fixture moves within the leveling machine. Compared to direct compression straightening throughout the entire process, it is easier to straighten the box panel parts to the standard state.

[0021] 4. The axial distance between the upper and lower straightening slides is 45mm. Therefore, regardless of whether the standard diameter of the rollers in the leveling machine is mostly 42mm, 88mm or 120mm, when the straightening fixture is transported into the leveling machine, the rollers located directly above or below the straightening fixture will not have a situation where one part of the roller abuts against the upper or lower straightening slide while the other part of the roller cannot act on the upper or lower straightening slide. This ensures the synchronicity of the force on the equally spaced upper or lower straightening slides, thereby making the force on the box panel parts more uniform and ultimately improving the straightening effect of the box panel parts.

[0022] 5. A guide cavity is formed by the product guide pillars to guide the sliding of the panel parts in the vertical direction. The guide cavity facilitates quick positioning of the panel parts and restricts their horizontal sliding or rotational displacement around the vertical axis. In addition, product clamping components are fixed on the upper and lower base plates to prevent the panel parts from moving vertically. After the upper and lower base plates are fixed to each other, the panel parts are clamped, thereby preventing the panel parts from shaking and causing additional deformation during the straightening process.

[0023] 6. At least one base plate positioning post is fixedly connected to the top four sides of the lower base plate to position the distance between the lower base plate and the upper base plate. This prevents the squeezing force on the upper and lower base plates in the leveling machine from being transmitted to the box plate parts, thus preventing damage to the unevenness of the box plate parts in the standard state.

[0024] 7. A substrate guide assembly for positioning and assembling the upper and lower substrates is provided between the upper substrate and the lower substrate, making the assembly between the upper substrate and the lower substrate more convenient and faster. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] For ease of understanding, the specific structure and operation of the present invention will be further described below with reference to the accompanying drawings:

[0039] The specific structure of this invention is as follows: Figure 1-11 As shown, its main structure includes a leveling machine 1 and a straightening fixture.

[0040] Specifically, such as Figure 1As shown, the orthopedic fixture includes an upper base plate 10 and a lower base plate 20 that are parallel to each other and fixed together by a fixing buckle 50. This fixes the entire box panel part A between the upper base plate 10 and the lower base plate 20, preventing deformation or shaking of the box panel part A during local orthopedic treatment, which would reduce the orthopedic effect. Furthermore, an upper orthopedic slider 90a and a lower orthopedic slider 90b slide through the upper base plate 10 and the lower base plate 20 respectively along the vertical direction. The extreme positions of the upper orthopedic slider 90a and the lower orthopedic slider 90b as they slide inward are adapted to the overall shape of the box panel part A. When the upper orthopedic slider 90a and the lower orthopedic slider 90b slide inward to their extreme positions, their inner ends are in contact with the surface of the box panel part A in its standard state. In use, the straightening fixture is fed into a traditional leveling machine. The upper and lower rollers in the leveling machine press the outer ends of the upper straightening slide 90a and the lower straightening slide 90b inward. When the outer ends of the upper straightening slide 90a and the lower straightening slide 90b are pressed, the inner ends of the upper straightening slide 90a and the lower straightening slide 90b slide inward to the set limit position. By sliding the upper straightening slide 90a and the lower straightening slide 90b inward and colliding with the box plate part A, and pressing the deformed part of the box plate part A, the deformed part of the box plate part A is straightened to the standard state.

[0041] In the above embodiments, the fixing buckle 50 can be any fastener in the prior art that can fix the upper substrate 10 and the lower substrate 20 to each other. Specifically, bolts that are respectively connected to the upper substrate 10 and the lower substrate 20 can be provided on a straight plate or a C-shaped plate; or a screw that is perpendicular to the surface of the upper substrate 20 and penetrates the upper substrate 20 can be provided on the lower substrate 10, and the upper substrate 10 and the lower substrate 20 can be locked and fixed to each other by using the locking nut on the screw.

[0042] More specifically, such as Figure 5 and Figure 6 As shown, both the upper correcting slider 90a and the lower correcting slider 90b are axial structures with their axes distributed along the vertical direction. The outer ends of both the upper and lower correcting sliders 90a and 90b are detachably fixed with pressure heads 91. The inner end of the pressure head 91 abuts against the upper substrate 10 or the lower substrate 20, thereby positioning the upper correcting slider 90a or the lower correcting slider 90b at its set limit position. In actual implementation, by replacing pressure heads 91 with different shapes, the set limit position of the upper correcting slider 90a or the lower correcting slider 90b can be adjusted according to different needs. Of course, in actual implementation, a shim 93 can be detachably fixed to the inner end of the pressure head 91, and the inner end of the shim 93 abuts against the upper substrate 10 or the lower substrate 20, thereby positioning the set limit position of the upper correcting slide 90a or the lower correcting slide 90b. In this embodiment, the pressure head 91 can adopt a uniform shape, and the set limit position of the upper correcting slide 90a or the lower correcting slide 90b can be adjusted by replacing the shims 93 of different thicknesses.

[0043] Based on the above, such as Figure 3 and Figure 4 As shown, for the case where there are many disseminated areas requiring straightening in box panel part A, from a top-down perspective, both the upper straightening slide 90a and the lower straightening slide 90b are arranged in a matrix. Each shaft-like upper straightening slide 90a and lower straightening slide 90b individually straightens each area of ​​box panel part A. Compared to using a single upper straightening slide 90a with a larger inner end area in conjunction with a single lower straightening slide 90b, this effectively prevents the problem of poor straightening effect in some areas due to stress dispersion during the straightening and pressing process. Furthermore, since the upper and lower rollers in the leveling machine are often arranged in several groups spaced apart along the straightening conveying direction, the matrix arrangement of the upper and lower straightening slides 90a and 90b allows for multiple compressions by the several groups of upper and lower rollers, further ensuring the straightening effect. Of course, in actual implementation, if the box panel part A requires few and concentrated correction points, a single upper correction slide 90a with a larger inner end area and a single lower correction slide 90b can be used.

[0044] In addition, such as Figure 5-9As shown, both the upper correcting slider 90a and the lower correcting slider 90b are fitted with central guide sleeves 92, which are respectively fixed to the lower surface of the upper substrate 10 and the upper surface of the lower substrate 20, to ensure stable sliding of the upper correcting slider 90a and the lower correcting slider 90b along their own axial direction. Furthermore, since the distance between a portion of the lower surface of the box plate part A and the top of the lower substrate 20 is relatively large, a larger axial length is required for some of the lower correcting sliders 90b. Therefore, an extended guide sleeve 96, fixedly connected to the lower substrate 20, is fitted on the rod near the inner end of the lower correcting slider 90b to further ensure the stability of the sliding of this type of lower correcting slider 90b. Both the upper straightening slide 90a and the lower straightening slide 90b are fitted with return springs 94 that compress them to produce an outward sliding action. Both the upper straightening slide 90a and the lower straightening slide 90b have protrusions 95 on their shafts to position their outer ends. The state in which the upper straightening slide 90a and the lower straightening slide 90b are not compressed by the rollers is the non-working state. The setting of the protrusions 95 and the return springs 94 ensures that the outer ends of all the upper straightening slides 90a are located on the same horizontal plane when they are not working, thereby effectively preventing the straightening fixture from being obstructed in the leveling machine due to unevenness between the upper straightening slides 90a and the lower straightening slide 90b. Furthermore, since both the upper straightening slide 90a and the lower straightening slide 90b have an outward sliding tendency when not in operation, they are often separated from the box panel part A in the initial non-operational state. Therefore, during the straightening process, the upper straightening slide 90a and the lower straightening slide 90b will first be squeezed and pushed to collide with the box panel part A, and then squeeze the box panel part A for straightening. This allows the upper straightening slide 90a and the lower straightening slide 90b to achieve a straightening action similar to continuous hammering during the movement of the straightening fixture in the straightening machine. Compared to direct pressing straightening throughout the process, it is easier to straighten the box panel part A to the standard state.

[0045] It is worth mentioning that, due to the staggered arrangement of the upper and lower rollers in traditional leveling machines, and the fact that the standard diameters of the rollers are mostly 42mm, 88mm, and 120mm, with adjacent rollers spaced 45mm apart when the diameter is 42mm, 90mm apart when the diameter is 88mm, and 135mm apart when the diameter is 120mm, in actual implementation, based on the upper straightening slide 90a and lower straightening slide 90b being set as several in a dot matrix distribution, such as... Figure 7-9 As shown, the spacing between the axes of adjacent upper correcting slides 90a and the spacing between the axes of adjacent lower correcting slides 90b are both 45mm. The upper correcting slides 90a and lower correcting slides 90b correspond one-to-one with each other or are horizontally offset by 22.5mm. Furthermore, the outer ends of all upper correcting slides 90a and all lower correcting slides 90b are flush. In this distribution configuration, as... Figure 9 As shown, when the diameter of the leveling machine rollers is 42mm, since the distance between adjacent rollers at this diameter is 45mm, the distance between the rollers and the axis of the adjacent upper straightening slide 90a is equal to the distance between the axis of the adjacent lower straightening slide 90b. When the straightening fixture is conveyed into the leveling machine, the adjacent upper rollers can press against the adjacent upper straightening slide 90a, and the adjacent lower rollers can press against the adjacent lower straightening slide 90b. Therefore, under this distribution, the upper straightening slide 90a and the lower straightening slide 90b can correspond one-to-one with each other or be horizontally offset by 22.5mm. Figure 7 As shown, when the diameter of the leveling machine rollers is 88mm, the distance between adjacent rollers is 90mm. The upper straightening slide 90a and the lower straightening slide 90b can be configured to correspond one-to-one with each other. Adjacent upper rollers can press against two upper straightening slides 90a separated by an upper straightening slide 90a, and the same applies to the lower straightening slide 90b. Figure 8 As shown, when the diameter of the leveling machine roller is 120mm, the distance between adjacent rollers is 135mm. The upper straightening slide 90a and the lower straightening slide 90b can be set to be horizontally offset by 22.5mm. The adjacent upper rollers can squeeze the two upper straightening slides 90a that are separated by two upper straightening slides 90a in the middle. The same applies to the lower straightening slide 90b. Obviously, in the above-mentioned layout of the upper straightening slide 90a and lower straightening slide 90b, regardless of whether the standard diameter of the rollers in the leveling machine is mostly 42mm, 88mm or 120mm, when the straightening fixture is transported into the leveling machine, the rollers located directly above or below the straightening fixture will not have a situation where one part of the roller abuts against the upper straightening slide 90a or lower straightening slide 90b while the other part of the roller cannot act on the upper straightening slide 90a or lower straightening slide 90b. This ensures the synchronicity of the force on the equally spaced upper straightening slide 90a or lower straightening slide 90b, thereby making the force on the box panel part A more uniform and ultimately improving the straightening effect of the box panel part A.

[0046] To ensure that panel component A is stably positioned and clamped between the upper substrate 10 and the lower substrate 20, at least one product guide post 60 is arranged on each side of panel component A on the top surface of the lower substrate 20. All product guide posts 60 enclose a guide cavity for sliding and guiding panel component A in the vertical direction. The guide cavity facilitates quick positioning of panel component A and restricts panel component A from sliding horizontally or rotating around the vertical axis. In addition, a product clamping assembly 70 is fixed on the upper substrate 10 and the lower substrate 20 to prevent panel component A from moving vertically. After the upper substrate 10 and the lower substrate 20 are fixed to each other, panel component A is clamped, thereby preventing panel component A from shaking and causing additional deformation during the straightening process.

[0047] Furthermore, the product clamping assembly 70 includes a lower corner clamping block 71a and a lower internal clamping block 71b fixed on the lower substrate 20. The product clamping assembly 70 also includes an upper corner clamping block 72a and an upper internal clamping block 72b fixed on the upper substrate 10. The lower corner clamping block 71a and the upper corner clamping block 72a are each arranged in four groups at the corners of the box panel part A to clamp the four corners of the box panel part A. The lower internal clamping block 71b and the upper internal clamping block 72b are arranged in several groups that correspond one-to-one and are distributed in the middle of the box panel part A to clamp the middle of the box panel part A. By employing a distributed multi-point clamping method, during the process of locking and fixing the upper substrate 10 and the lower substrate 20 together with the fixing buckle 50, the upper substrate 20 and the lower substrate 10 move towards each other. This allows the lower corner clamping block 71a and the lower internal clamping block 71b on the lower substrate 20, as well as the upper corner clamping block 72a and the upper internal clamping block 72b on the upper substrate 10, to achieve clamping at all corners and the middle of the box panel part A. This disperses the clamping stress on the box panel part A, achieving uniform clamping of the entire box panel part A and further ensuring the stability of the clamping of the box panel part A.

[0048] In addition, to further prevent the box panel part A from shifting during the straightening process, such as Figure 3 and Figure 11 As shown, a positioning pin 30 is fixed on the top surface of the lower substrate 20, which is engaged with the existing hole A1 on the box panel part A. Specifically, the position of the positioning pin 30 is determined according to the position of the existing hole A1 on the box panel part A with different structures.

[0049] And, as Figure 3 As shown, at least one base plate positioning post 80 is fixedly connected to each of the four sides of the top of the lower base plate 20 to position the distance between the lower base plate 20 and the upper base plate 10. This can prevent the extrusion pressure on the upper base plate 10 and the lower base plate 20 in the leveling machine from being transmitted to the box plate part A, thereby preventing damage to the existing unevenness in the plate structure of the box plate part A under standard conditions.

[0050] In addition, to facilitate rapid assembly between the upper substrate 10 and the lower substrate 20, such as Figure 2 , Figure 3 and Figure 4 As shown, a substrate guide assembly 40 for positioning and assembling with each other is provided between the upper substrate 10 and the lower substrate 20. The substrate guide assembly 40 includes a substrate guide post 41 fixed on the top surface of the lower substrate 20 and a substrate guide sleeve 42 disposed on the upper substrate 10 and inserted into the substrate guide post 41.

[0051] Of course, those skilled in the art will recognize that the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
