Description

Technical Field

[0001] This application relates to the field of locomotive frames, and in particular to a deformation-resistant tooling. Background Technology

[0002] Rail locomotives are the main equipment in the rail transit field. A locomotive consists of a car body and bogies. The bogies include axle drive units and a frame. The axle drive units are mounted on the locomotive via the frame. During locomotive operation, the wheel flanges require grease lubrication. Therefore, grease tanks are installed on the locomotive frame. The grease tanks are mounted to the frame via grease tank holders, which are usually welded to the locomotive frame.

[0003] During the locomotive frame welding process, the installation position accuracy of the grease tank seat is required to be extremely high (tolerance of ±0.25mm). The grease tank seat is connected to the locomotive frame by machining first and then welding. Therefore, before welding, tooling is needed to position the grease tank seat on the locomotive frame to ensure the installation position accuracy of the grease tank seat.

[0004] The existing tooling uses an integrated positioning structure with separate positioning holes and 3mm steel plate support. The positioning plate is not strong enough and is prone to deformation, which makes the installation position of the grease tank seat easily shift, failing to meet the installation position accuracy requirements of the grease tank seat. In addition, the existing tooling is complicated to install and is not conducive to reducing costs. Utility Model Content

[0005] The main purpose of this application is to provide a high-precision, split-type anti-deformation tooling with a high-strength positioning plate that is not easily deformed.

[0006] To achieve the above objectives, this application adopts the following technical solution: According to one aspect of this application, a deformation-resistant fixture is provided for preventing welding deformation caused by welding a seat component to a locomotive frame. The fixture includes a first positioning plate and a second positioning plate. The first positioning plate includes a first left end, a first right end, and a first intermediate portion connecting the first left end and the first right end. The first left end has a left positioning surface, and the first right end has a right positioning surface. The left and right positioning surfaces are configured to position the first positioning plate between a symmetrical brake seat of the locomotive frame and a terminal block of the locomotive frame. The second positioning plate includes a second end and a second intermediate portion connecting the second end. The second end is connected to the seat component, and the second intermediate portion is connected to the first intermediate portion.

[0007] According to one embodiment of this application, the second positioning plate includes four second ends, each of which has a positioning hole for connecting the seat device.

[0011] According to one embodiment of this application, the first intermediate portion is provided with a plurality of first connecting holes, and the second intermediate portion is provided with a plurality of second connecting holes, wherein one of the first connecting holes and one of the second connecting holes are paired to form a set of connecting structures, and the axes of the first connecting hole and the second connecting hole in each set of connecting structures are on a straight line.

[0012] According to one embodiment of this application, both the left positioning surface and the right positioning surface are curved surfaces.

[0013] According to one embodiment of this application, the anti-deformation tooling further includes a detection plate, the shape of which is the same as that of the second positioning plate, for detecting the positional accuracy of the second end.

[0015] According to one embodiment of this application, both the first positioning plate and the second positioning plate are made of stainless steel, the thickness of the first positioning plate is 4mm-8mm, and the thickness of the second positioning plate is 6mm-10mm.

[0016] As can be seen from the above technical solution, the advantages and positive effects of the anti-deformation tooling proposed in this application are as follows: The anti-deformation fixture proposed in this application uses two positioning plates connected together, which can improve the strength of the positioning plates and prevent the positioning plates from deforming due to the welding process between the grease tank seat and the locomotive frame. This can avoid the installation position of the grease tank seat from shifting and can meet the extremely high precision requirements of the grease tank seat installation position.

[0017] The anti-deformation fixture proposed in this application has left and right positioning surfaces at both ends of the first positioning plate. The left and right positioning surfaces are configured to position the first positioning plate between the symmetrical brake seat and the terminal block of the locomotive frame. It offers accurate positioning, simple operation, and high positioning precision.

[0018] The anti-deformation tooling proposed in this application is provided with a second end connecting seat device for the second positioning plate, and the second middle part of the second positioning plate is connected to the first middle part; it can further prevent the positioning plate from deforming due to the welding process between the grease tank seat device and the locomotive frame, thereby avoiding the offset of the installation position of the grease tank seat device, and meeting the extremely high precision requirements of the installation position of the grease tank seat.

Detailed Implementation

[0027] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0028] In the following description of various exemplary embodiments of this application, reference is made to the accompanying drawings, which form part of this application, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this application. It should be understood that other specific solutions to components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this application. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this application, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this application.

[0029] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0030] As used herein, “about,” “approximately,” “essentially,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or, for example, within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” “essentially,” or “substantially” herein may be chosen to select a more acceptable range of deviations or standard deviations depending on the nature of the measurement, the cutting nature, or other properties, and may not require a single standard deviation to apply to all properties.

[0031] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being “down” to another element will be oriented “up” to that element. Thus, the exemplary term “down” can include both “down” and “up” orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being “below” or “under” another element will be oriented “above” that element. Thus, the exemplary terms “above” or “below” can include both “up” and “down” orientations.

Therefore, variations in the shape of the illustrations can be expected as a result of, for example, manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include, for example, shape deviations caused by manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, the acute angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0033] See Figure 1 , Figure 2 and Figure 7This example illustrates the anti-deformation fixture 1 of this application, used to prevent welding deformation caused by the welding connection between the seat device 2 and the locomotive frame 3. In this embodiment, the seat device 2 is a grease tank seat 2. In other embodiments, the seat device 2 may be other bases. In the following description of this embodiment, the grease tank seat 2 is used instead of the seat device 2. The grease in the grease tank 4 is used for lubricating the wheel flanges of the locomotive. The grease tank 4 is connected to the locomotive frame 3 through the grease tank seat 2. The grease tank seat 2 is welded to the precise position of the locomotive frame 3. The grease tank 4 is installed on the grease tank seat 2, completing the connection between the grease tank 4 and the locomotive frame 3.

[0034] The anti-deformation tooling 1 of this application includes a first positioning plate 10 and a second positioning plate 20. The first positioning plate 10 includes a first left end 101, a first right end 102, and a first intermediate portion 103 connecting the first left end 101 and the first right end 102. The first left end 101 has a left positioning surface 1011, and the first right end 102 has a right positioning surface 1021. The left positioning surface 1011 and the right positioning surface 1021 are configured to position the first positioning plate 10 between the symmetrical brake seat 31 of the locomotive frame 3 and the terminal block 32 of the locomotive frame 3. The second positioning plate 20 includes a second end 201 and a second intermediate portion 202 connecting the second end 201. The second end 201 is connected to the grease tank seat 2, and the second intermediate portion 202 is connected to the first intermediate portion 103.

[0035] The anti-deformation fixture 1 of this application uses two positioning plates (10, 20) connected together, which can improve the strength of the positioning plates and prevent the positioning plates from deforming during the welding process between the grease tank seat 2 of the grease tank 4 and the locomotive frame 3. The second end 201 of the second positioning plate 20 is connected to the grease tank seat 2, and the second middle part 202 of the second positioning plate 20 is connected to the first middle part 103. This can further prevent the positioning plates from deforming during the welding process between the grease tank seat 2 of the grease tank 4 and the locomotive frame 3, thereby avoiding the offset of the installation position of the grease tank seat 2 of the grease tank 4, and meeting the extremely high precision requirements of the installation position of the grease tank seat 2. The first positioning plate 10 has left and right positioning surfaces at both ends, wherein the left positioning surface 1011 and the right positioning surface 1021 are configured to position the first positioning plate 10 between the symmetrical brake seat 31 of the locomotive frame 3 and the terminal block 32 of the locomotive frame 3. The positioning is accurate, the operation is simple, and the positioning accuracy is high.

[0036] In this embodiment, see Figure 3 The left positioning surface 1011 and the right positioning surface 1021 of the first positioning plate 10 are both curved surfaces, and in this embodiment, they are both circular arc surfaces. See also... Figure 1wherein the left positioning surface 1011 is matched with the symmetric brake seat 31 of the locomotive frame 3, and the right positioning surface 1021 is matched with the terminal post 32 of the locomotive frame 3; the left positioning surface 1011 and the right positioning surface 1021 jointly realize the positioning of the first positioning plate 10 relative to the locomotive frame 3. Arc positioning can achieve accurate and precise positioning, and the left and right positioning surfaces can achieve stable positioning. With the anti-deformation tool 1 as the main body, the end of the anti-deformation tool 1 that contacts the symmetric brake seat 31 of the locomotive frame 3 can be defined as the left end, and the end that contacts the terminal post 32 of the locomotive can be defined as the right end. The left and right designations are only for facilitating the clear description of the structure of the anti-deformation tool 1 of the present application, and do not constitute a limitation on the anti-deformation tool 1 of the present application. For example, the end of the anti-deformation tool 1 that contacts the symmetric brake seat 31 of the locomotive frame 3 can also be defined as the right end, and the end that contacts the terminal post 32 of the locomotive can be defined as the left end. In this case, the left and right designations of other structures can be interchanged accordingly.

[0037] In this embodiment, the first intermediate portion 103 of the first positioning plate 10 is provided with a plurality of first connection holes 1031, which are three in this embodiment, and may also be four or more in some other embodiments. Three or more connection holes can achieve stable connection and high precision. The first intermediate portion 103 is of a hollow structure, which can reduce the weight of the first positioning plate 10 and save materials at the same time.

[0038] In this embodiment, the first positioning plate 10 is generally in a "zhong" (Chinese character for middle) shape, wherein the upper and lower ends of the "zhong" shape respectively correspond to the first left end portion 101 and the first right end portion 102 of the first positioning plate 10, and the middle part of the "zhong" shape corresponds to the first intermediate portion 103 of the first positioning plate 10. The first intermediate portion 103 is generally a parallelogram, and the first connection holes 1031 are provided on two opposite edges of the parallelogram.

[0039] In this embodiment, the first positioning plate 10 is made of a stainless steel plate, and the thickness of the first positioning plate 10 is 4mm-8mm. For example, it can be 5mm, 6mm or 7mm. The stainless steel plate is sturdy, durable, high in strength and not easy to deform, which can prevent the first positioning plate 10 from deforming during the welding process of the grease tank seat 2, thereby avoiding position deviation of the grease tank seat 2 and insufficient welding position accuracy of the grease tank seat 2. The first positioning plate 10 is processed integrally, which can ensure the position accuracy of the three first connection holes 1031.

[0040] In this embodiment, referring to Figures 4 to 5 , the second positioning plate 20 includes four second end portions 201, and each second end portion 201 is provided with a positioning hole 203 for connecting the grease tank seat 2. A threaded hole is provided on the grease tank seat 2, and the axis of the threaded hole and the axis of the positioning hole 203 are on the same straight line. A screw passes through the positioning hole 203 to connect with the threaded hole, so that the grease tank seat 2 can be fixed on the second end portion 201 of the second positioning plate 20.

[0041] See Figure 4 In this embodiment, the grease tank holder 2 may include a boss 21. Two of the second positioning plates 20 are provided with stepped grooves 2011 and 2012 on the second end 201 of the grease tank holder 2 with the boss 21. The boss 21 is provided on the grease tank holder 2 and is configured to be located in the stepped groove to prevent the grease tank holder 2 from detaching from the anti-deformation fixture 1. The stepped groove enables precise positioning of the grease tank holder 2 and allows the grease tank holder 2 to be tightly connected to the anti-deformation fixture 1, further improving the positional accuracy of the grease tank holder 2.

[0042] The stepped groove includes a stepped groove 2011 on which the boss 21 can be placed, and a stepped groove 2012 into which the boss 21 can be inserted. The shape of the stepped groove can be changed according to the shape of the boss 21 of the grease tank 2.

[0043] In this embodiment, see Figure 2 , Figure 3 and Figure 4 , Figure 5 The second intermediate part 202 is provided with multiple second connecting holes 2021. A first connecting hole 1031 and a second connecting hole 2021 are paired to form a connecting structure 100. The axes of the first connecting hole 1031 and the second connecting hole 2021 in each connecting structure 100 are on a straight line. This allows the second positioning plate 20 to be precisely connected to the first positioning plate 10, thereby ensuring the positional accuracy of the second end 201 of the second positioning plate 20 and the positional accuracy of the grease tank seat 2. The first connecting hole 1031 and the second connecting hole 2021 can be connected using bolts or washers.

[0044] In this embodiment, there are three second connecting holes 2021; in some other embodiments, there may be four or more. The second intermediate portion 202 has a hollow structure, which can reduce the weight of the second positioning plate 20 and save materials. The number of second connecting holes 2021 is equal to the number of first connecting holes 1031.

[0045] The hollow structure of the first intermediate part 103 and the second intermediate part 202 can also avoid the influence of the welding beads of the locomotive frame 3 on the positioning accuracy of the anti-deformation tooling, thereby avoiding the influence of the welding beads of the locomotive frame 3 on the positional accuracy of the grease tank seat 2.

[0046] In this embodiment, the second positioning plate 20 is approximately "X"-shaped, with the four top and bottom vertices of the "X" corresponding to the four second end portions 201 of the second positioning plate 20. A horizontal plate is added to the middle portion of the "X" shape, forming a triangular structure at the intersection of the horizontal plate and the "X" shape. This triangular structure corresponds to the second middle portion 202 of the second positioning plate 20. The intersection of the "X" shape is the vertex of the triangle, and the horizontal plate forms the base of the triangle. Second connecting holes 2021 are provided on the base and vertices of the triangle, with two second connecting holes 2021 on the base and one second connecting hole 2021 at the vertex. The position of the first connecting hole 1031 corresponds to the position of the second connecting hole 2021. The second positioning plate 20 is CNC machined in one piece, ensuring the positional accuracy of the four positioning holes 203 and the positional accuracy of the stepped grooves 2011 and 2012.

[0047] See Figures 4 to 6 The positioning hole 203 on the second end 201 includes a tapered hole 2031 with a taper of 1:(5-10). The tapered hole 2031 design avoids the wear and tear of the cylindrical positioning hole 203 in the prior art, which reduces positioning accuracy. The taper of the tapered hole 2031 (1:(5-10)) facilitates machining and provides high centering accuracy.

[0048] In this embodiment, the second positioning plate 20 is made of stainless steel plate, and the thickness of the second positioning plate 20 is 6mm-10mm. For example, it can be 7mm, 8mm or 9mm. Stainless steel plate is sturdy and durable, has high strength and is not easily deformed, which can prevent the second positioning plate 20 from deforming during the welding process of the grease tank seat 2, thereby causing the position of the grease tank seat 2 to shift and the welding position accuracy of the grease tank seat 2 to be insufficient.

[0049] In this embodiment, the anti-deformation tooling 1 also includes a detection plate, which has the same shape as the second positioning plate 20 and is used to detect the positional accuracy of the second end 201. The design of the detection plate can avoid the situation in the prior art where tooling deformation is difficult to detect, leading to batch deviations and difficulties in repair.

[0050] Figure 7 This diagram illustrates the welding of the grease tank seat 2 to the locomotive frame 3 using the anti-deformation fixture 1, and the installation of the grease tank 4 onto the locomotive frame 3. The anti-deformation fixture 1 of this application prevents the positioning plate from deforming during the welding process between the grease tank seat 2 of the grease tank 4 and the locomotive frame 3, thus avoiding any displacement of the installation position of the grease tank seat 2 and ensuring the accuracy of the installation position of the grease tank seat 2.

[0051] The above is a detailed description of several exemplary embodiments of the anti-deformation tooling 1 proposed in this application. The following will describe in detail the usage process of the anti-deformation tooling 1 proposed in this application.

[0052] Combined with appendix Figures 1 to 7 The process of using the anti-deformation tooling 1 proposed in this application is as follows: First, the second positioning plate 20 is fixed to the first positioning plate 10 through the second connecting hole 2021 and the second connecting hole 2021. Bolts or screws or other fasteners can be used for fixing.

[0053] Then, after connecting the grease tank seat 2 and the second end 201 of the second positioning plate 20 together with screws, the left positioning surface 1011 of the first fixing plate is positioned against the symmetrical brake seat 31 of the locomotive frame 3, and the right positioning surface 1021 of the first fixing plate is positioned against the terminal block 32 of the locomotive frame 3.

[0054] Push the entire structure of the anti-deformation tooling 1 toward the locomotive frame 3 until the grease tank seat 2 abuts against the locomotive frame 3, weld each grease tank seat 2 onto the locomotive frame 3, and then remove the screws of the second end 201 of the second positioning plate 20, so that the grease tank seat 2 is welded onto the locomotive frame 3.

[0055] As can be seen from the above usage process of the anti-deformation tooling 1, the use of two positioning plates connected together in this application can improve the strength of the positioning plates and prevent the positioning plates from deforming due to the welding process between the seat device 2 of the grease tank 4 and the locomotive frame 3. This can prevent the installation position of the seat device 2 of the grease tank 4 from shifting and can meet the extremely high precision requirements of the installation position of the grease tank seat 2.

[0056] In summary, the anti-deformation tooling proposed in this application includes a first positioning plate and a second positioning plate connected together. This improves the strength of the positioning plate and prevents deformation during the welding process between the grease tank's seat and the locomotive frame. The first positioning plate includes a first left end, a first right end, and a first intermediate portion connecting the first left end and the first right end. The first left end has a left positioning surface, and the first right end has a right positioning surface. The left and right positioning surfaces are configured to position the first positioning plate between the symmetrical brake seat and the terminal block of the locomotive frame. The positioning is accurate, easy to operate, and has high positioning precision. The second positioning plate includes a second end and a second intermediate portion connecting the second end. The second end connects to the seat, and the second intermediate portion connects to the first intermediate portion. This further prevents deformation of the positioning plate during the welding process between the grease tank's seat and the locomotive frame, thereby avoiding displacement of the grease tank's seat position.
