Abstract
Description
Technical Field
[0001] The utility model relates to a universal tool for supporting a power assembly of a three-bridge mine car, belonging to the technical field of three-bridge mine cars. Background Art
[0002] The company's three-axle mining truck production line (light truck, wide-body truck, and articulated truck) operates on a single line. The engine or motor for each model within each product line varies in type and structure, resulting in different support positions. To ensure smooth powertrain assembly, each model is currently equipped with a dedicated set of support fixtures based on its structure. When switching between models, the corresponding support fixtures must be replaced in advance.
[0003] Sanqiao Mining Cars has a wide variety of products and requires frequent changes. Each changeover requires personnel to identify the corresponding tooling in the tooling storage area in advance, then use a forklift to transport it to the assembly plant's sub-assembly station. Once the product comes off the assembly line, it is then hoisted to the engine sub-assembly line using a crane. After use, personnel are assigned to transport it back to the tooling storage area using both a crane and a forklift. This entire process wastes significant time and manpower, occupies some of the available time for the crane and forklift, and results in a considerable waste of storage space. Summary of the Invention
[0004] In view of the deficiencies in the prior art, the utility model provides a universal tooling for supporting the powertrain components of a three-axle mining car, which is suitable for supporting the powertrains of all current conventional models.
[0005] The utility model is implemented according to the following technical solutions:
[0006] A universal tooling for supporting the powertrain assembly of a three-axle mining car, comprising:
[0007] The support frame includes a square bottom frame and a mounting frame fixed at each of the four corners of the bottom frame and extending vertically upward perpendicular to the bottom frame;
[0008] Four telescopic components are inserted into corresponding mounting frames to support the powertrain, and the telescopic components can move up and down in the mounting frames to adjust the corresponding support height according to the mounting height position of the powertrain of each model;
[0009] A plurality of detachable fastening components act between the mounting frame and the telescopic component and are used to fix the telescopic component after the height is adjusted on the mounting frame.
[0010] In some embodiments, the telescopic component is composed of a telescopic tube and a support plate fixed to the top end of the telescopic tube; the transverse cross-sectional shape of the telescopic tube is adapted to the transverse cross-sectional shape of the inner hole of the mounting frame, so that the telescopic tube can be inserted into the mounting frame.
[0011] In some embodiments, the center point of the support plate does not coincide with the central axis of the telescopic tube, so that the support plate is fixed to the telescopic tube in an eccentric manner. By changing the installation direction of the telescopic tube on the mounting frame, the support position of the support plate on the powertrain can be adjusted to accommodate powertrains of different sizes or different suspension orientations.
[0012] In some embodiments, a mounting hole is provided on the side elevation of the mounting frame near the top surface, and a plurality of positioning holes with different orientations are provided on the side elevation of the telescopic tube from top to bottom, each positioning hole corresponding to the suspension height position and suspension orientation position of a type of powertrain; when the selected positioning hole is aligned with the mounting hole according to the pre-assembled powertrain, the two are fixed together by installing the detachable fastening component.
[0013] In some embodiments, the telescopic tube located near each positioning hole is provided with an installation identification component corresponding to the pre-assembled power assembly of the positioning hole.
[0014] In some embodiments, the bottom frame is provided with an auxiliary support which is still unable to support the powertrain after the installation direction of the telescopic tube on the mounting frame is changed, and the auxiliary support is used to support a powertrain of another type.
[0015] In some embodiments, the auxiliary support is composed of multiple H-shaped auxiliary frames of different sizes. The selected H-shaped auxiliary frame is placed on the bottom frame according to the pre-assembled powertrain. The H-shaped auxiliary frame cooperates with the two telescopic components on the same side to support the powertrain.
[0016] In some embodiments, auxiliary support blocks flush with the top surfaces of all or part of the mounting frames are fixed to the side elevations thereof, and when the telescopic tube is completely inserted into the mounting frame, the auxiliary support blocks can lift and support the support plate.
[0017] In some embodiments, a flexible spacer matching the contour of the support plate is fixed on the top surface of the support plate.
[0018] In some embodiments, it also includes at least two V-shaped supports arranged in parallel and spaced apart. The V-shaped support consists of an upper V-shaped seat and a lower N-shaped seat. The N-shaped seat is clamped on the bottom frame, and the powertrain with a cylindrical structure is supported by the upper V-shaped seat.
[0019] In some embodiments, the detachable fastening component is a pin shaft and a cotter pin. The pin shaft transversely passes through the mounting frame and the telescopic component and is then inserted into the cotter pin to limit the axial movement of the pin shaft.
[0020] Beneficial effects of the utility model:
[0021] 1. Applicable to the support of all current conventional models of powertrain;
[0022] 2. It reduces the waiting time of the logistics forklift when switching special tooling and the time the forklift is occupied, freeing up some manpower and forklifts;

DETAILED DESCRIPTION
[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0036] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0037] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0038] like Figure 1 As shown, a universal tooling for supporting the powertrain of a three-axle mining car comprises a support frame, four telescopic components and a plurality of detachable fastening components; the support frame comprises a square bottom frame 1 and a mounting frame 4 extending vertically upward perpendicular to the bottom frame 1, each fixed at the four corners of the bottom frame 1; the four telescopic components are respectively inserted into the corresponding mounting frames 4 for supporting the powertrain, and the telescopic components can move up and down in the mounting frames 4, and thus can adjust their corresponding support heights according to the suspension height positions of the powertrains of various models; a plurality of detachable fastening components act between the mounting frame 4 and the telescopic components for fixing the telescopic components after adjusting the height to the mounting frame 4.
[0039] The telescopic component mentioned above is further described below.
[0040] Continue to refer to Figure 1 As shown, the telescopic component consists of a telescopic tube 2 and a support plate 3 fixed to the top end of the telescopic tube 2; the transverse cross-sectional shape of the telescopic tube 2 is adapted to the transverse cross-sectional shape of the inner hole of the mounting frame 4, so that the telescopic tube 2 can be inserted into the mounting frame 4.
[0041] For further solutions, please refer to Figure 1As shown, the center point of the support plate 3 does not coincide with the central axis of the telescopic tube 2, so that the support plate 3 is fixed to the telescopic tube 2 in an eccentric manner. By changing the installation direction of the telescopic tube 2 on the mounting frame 4, the support position of the support plate 3 on the powertrain can be adjusted to accommodate powertrains of different sizes or different suspension orientations.
[0042] The specific implementation process is: when the engine width is large, the telescopic tube 2 can be rotated as a whole until the support plate 3 faces the outside of the engine; when the engine width is narrow, it can be rotated to the inside; when the engine is mounted forward, it can be rotated to the front side; when the engine is mounted backward, it can be rotated to the rear side.
[0043] Further solutions, such as Figure 2 As shown, a mounting hole 7 is provided on the side elevation of the mounting bracket 4 near the top surface, and a plurality of positioning holes 8 with different orientations are provided on the side elevation of the telescopic tube 2 from top to bottom. Each positioning hole 8 corresponds to the suspension height position and suspension orientation position of a type of powertrain. When the selected positioning hole 8 is aligned with the mounting hole 7 according to the pre-assembled powertrain, the two are fixed together by installing a detachable fastening component.
[0044] In a preferred solution, the detachable fastening components are a pin 5 and a cotter pin. The pin 5 transversely penetrates the mounting frame 4 and the telescopic tube 2 and is then inserted into the cotter pin to limit the axial movement of the pin 5.
[0045] It should be noted that the detachable fastening components are not limited to the above-mentioned pins and cotter pins, and may also be detachable parts such as bolts and nuts.
[0046] For further solutions, please refer to Figure 2 As shown, the telescopic tube 2 near each positioning hole 8 is provided with an installation identification component 6 corresponding to the pre-assembled power assembly of the positioning hole 8, so that inexperienced personnel can also achieve simple switching.
[0047] It should be noted that the installation identification component 6 can be a nameplate fixed by screws, or data information can be engraved on the telescopic tube through machining.
[0048] For further solutions, please refer to Figure 1 As shown, since the front telescopic tube 2 of some models needs to be lowered to the lowest position, in order to prevent the support plate 3 from being deformed due to excessive force, an auxiliary support block 10 is added flush with the upper end of the mounting frame 4 corresponding to the front telescopic tube 2 of the tooling. When the telescopic tube 2 is completely dropped into the mounting frame 4, the auxiliary support block 10 can lift and support the support plate 3.
[0049] For further solutions, please refer to Figure 1 As shown, a flexible spacer 9 adapted to the contour of the support plate 3 is fixed on the top surface of the support plate 3 .
[0050] In a preferred solution, the flexible spacer 9 is a polyurethane spacer. Of course, it is not limited to a polyurethane spacer, and may be other types of flexible spacers.
[0051] like Figure 3 As shown, because the spacing of engine mounts on certain types of articulated trucks and wide-body vehicles is much shorter than on other models, adjusting the orientation of the support plate 3 is no longer sufficient to adjust their position. Therefore, auxiliary supports are added to the base frame 1. These auxiliary supports consist of multiple H-shaped auxiliary brackets 11 of varying sizes. Selected H-shaped auxiliary brackets 11 are placed on the base frame 1 based on the pre-assembled powertrain. The H-shaped auxiliary brackets 11 work together with two telescopic components on the same side to support the powertrain.
[0052] In a further solution, the H-shaped auxiliary frame 11 is formed by welding a horizontally arranged square tube, a plurality of vertically arranged square tubes, two support plates at the top and two bases at the bottom.
[0053] like Figure 4 As shown, because the structure of an electric vehicle motor is completely different from that of a fuel vehicle engine, it is generally cylindrical and has a relatively small diameter. Therefore, at least two parallel and spaced V-shaped supports 12 are added to the base frame 1. The V-shaped supports 12 are composed of an upper V-shaped seat and a lower n-shaped bracket. The n-shaped bracket is connected to the base frame 1, and the upper V-shaped seat supports the cylindrical powertrain.
[0054] The above-mentioned support frame is further described below.
[0055] Continue to refer to Figure 1 As shown, the bottom frame 1 is composed of two transversely arranged square tubes and two longitudinally arranged square tubes welded together in four mounting frames 4, wherein the mounting frames 4 are square tubes and the telescopic tubes 2 are also square tubes.
[0056] It should be noted that the bottom frame 1 , the mounting frame 4 and the telescopic tube 2 are not limited to the above-mentioned square tube structure, and may also be designed as a circular tube structure.
[0057] In summary, the present invention provides a universal tooling for supporting the powertrain of a three-axle mining car, which achieves the following functions and effects:
[0058] 1. A telescopic tube is set up, which can be adjusted to switch the support height according to the height of the product suspension.
[0059] 2. The support plate is set eccentrically. The support position can be adjusted by rotating the four telescopic tubes inside the tooling according to the horizontal position of the product suspension.
[0060] 3. For some positions where the support cannot be achieved by adjusting the tooling, the bottom frame is used as the base and auxiliary supports are added to achieve the universalization of the support tooling.
[0061] 4. Each positioning hole is marked with the corresponding product logo, so even inexperienced personnel can easily switch, that is, one telescopic tube can support multiple powertrains.
[0062] The utility model is applicable to the support of powertrains of all current conventional models; it reduces the waiting time of the logistics forklift and the time occupied by the forklift when switching special tooling, thus releasing some manpower and forklifts; it reduces the time occupied by the driving in the assembly plant when switching special tooling, thus releasing the driving; it speeds up the reaction time of the line when switching products; the tooling can be placed at each work step of the engine assembly line, thus greatly reducing the waste of space occupied by multiple toolings; and the tooling cost investment is greatly reduced.
