Description

Technical Field

[0001] This utility model relates to the field of diesel engine manufacturing technology, and in particular to a transfer device for diesel engine castings. Background Technology

[0002] Diesel engines consist of many castings. During the production of diesel engine castings, transfer devices such as trolleys are frequently used to move the castings between different workstations or workshops. During the transfer of workpieces using trolleys, bumps are inevitable due to various reasons. Therefore, limit / positioning mechanisms are needed to limit the workpieces and ensure stability during the transfer process.

[0003] Existing transfer vehicles often have limiting / positioning mechanisms that are only suitable for limiting workpieces of one or a few specifications. However, diesel engine castings come in various types and specifications, making existing transfer vehicles highly limited and lacking in versatility when used for transporting them. Furthermore, existing transfer vehicles suffer from the problem that the limiting / positioning mechanisms can easily interfere with the placement of workpieces, making placement inconvenient. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a transfer device for diesel engine castings, which is highly versatile and convenient for placing diesel engine castings.

[0005] The diesel engine casting transfer device according to an embodiment of the present utility model includes:

[0006] A mobile vehicle having a horizontal support surface for placing diesel engine castings;

[0007] A lifting unit, which is vertically adjustable and located above the supporting surface, is mounted on the mobile vehicle.

[0008] A clamping part is provided on the lifting part, and the clamping part is used to abut and limit the top end of the diesel engine casting. The clamping part has a vertically distributed first axis.

[0009] Multiple clamping parts are provided on the lifting part and can be adjusted in position relative to the lifting part radially along the first axis. The multiple clamping parts are used to cooperate in clamping and fixing the diesel engine casting.

[0010] The diesel engine casting transfer device according to the embodiments of the present utility model has at least the following beneficial effects:

[0011] In use, first adjust the lifting unit to a high position so that the height difference between the lowest point of the lifting unit, clamping unit, and holding unit and the supporting surface is greater than the height of the diesel engine casting to be transferred. This avoids interference with the diesel engine casting when placing it, minimizing disturbance and facilitating the horizontal placement of the diesel engine casting on the supporting surface. After adjusting the lifting unit, place the diesel engine casting horizontally on the supporting surface, positioning it directly below the clamping unit. Then, adjust the holding unit radially outward along the first axis of the clamping unit, moving the multiple holding units away from each other to prevent interference between the holding units and the diesel engine casting when the lifting unit is lowered. Then lower... Adjust the lifting part until the clamping part is facing downwards and abuts against the diesel engine casting. Then, adjust the clamping part radially inwards along the first axis to move the multiple clamping parts closer to each other until all the clamping parts abut against the diesel engine casting, thus completing the positioning of the diesel engine casting. Then, the moving trolley can be moved for transfer. Since the clamping part can be adjusted vertically with the lifting part, it can be used for diesel engine castings of various height specifications. Since the clamping part can be adjusted radially along the first axis of the clamping part, it can be used for diesel engine castings of various transverse dimensions. Therefore, the diesel engine casting transfer device of this embodiment can be used for diesel engine castings of various specifications and has strong versatility.

[0052] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0055] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0056] Reference Figures 1 to 5 As shown, a diesel engine casting transfer device according to an embodiment of the present invention includes: a moving vehicle 100, a lifting part 200, a pressing part 300, and a clamping part 400.

[0057] The mobile cart 100 has a push-pull bracket and casters for easy movement and transfer; in addition, the mobile cart 100 has a horizontal support surface 101 for placing diesel engine castings (not shown in the figure).

[0058] The lifting unit 200 is vertically adjustable on the mobile vehicle 100, and the lifting unit 200 is located above the support surface 101.

[0059] The clamping part 300 is disposed on the lifting part 200 and can move vertically synchronously with the lifting part 200; the clamping part 300 is used to abut against the top of the diesel engine casting to vertically limit the diesel engine casting, and the clamping part 300 has a vertically distributed first axis.

[0060] A clamping part 400 is disposed on the lifting part 200, and the clamping part 400 can be adjusted in position relative to the lifting part 200 radially along the first axis. Multiple clamping parts 400 are provided, arranged at intervals along the circumference of the pressing part 300. These clamping parts 400 are used to clamp and fix the diesel engine casting; that is, the function of the multiple clamping parts 400 is to fix the diesel engine casting in the horizontal direction. The number of clamping parts 400 can be three, four, or more. Obviously, the clamping part 400 can move vertically synchronously with the lifting part 200. Furthermore, the clamping part 400 can also move radially relative to the lifting part 200 along the first axis. In some specific embodiments, the height of the clamping part 400 is lower than the height of the pressing part 300.

[0061] In this embodiment, the diesel engine casting transfer device first adjusts the lifting part 200 to a higher position so that the height difference between the lowest point of the lifting part 200, the clamping part 300, and the clamping part 400 and the support surface 101 is greater than the height of the diesel engine casting to be transferred. This avoids interference with the diesel engine casting when placing it, reduces interference, and facilitates the horizontal placement of the diesel engine casting on the support surface 101. After adjusting the lifting part 200, the diesel engine casting is placed horizontally on the support surface 101 so that it is directly below the clamping part 300. Then, the clamping part 400 is adjusted radially outward along the first axis of the clamping part 300 so that the multiple clamping parts 400 move away from each other, preventing the clamping parts 400 from interfering with each other when the lifting part 200 is lowered laterally. Interference occurs when the diesel engine casting is affected. Then, the lifting part 200 is lowered until the clamping part 300 abuts against the diesel engine casting downwards. Then, the clamping part 400 is adjusted radially inwards along the first axis, so that the multiple clamping parts 400 move towards each other until all the clamping parts 400 abut against the diesel engine casting, thus completing the positioning of the diesel engine casting. Then, the moving cart 100 can be moved for transfer. Since the clamping part 300 can be vertically adjusted with the lifting part 200, it can be used for diesel engine castings of various height specifications. Since the clamping part 400 can be radially adjusted along the first axis of the clamping part 300, it can be used for diesel engine castings of various transverse dimensions. Therefore, the diesel engine casting transfer device of this embodiment can be used for diesel engine castings of various specifications and has strong versatility.

[0062] It is understandable that the clamping part 300 can be fixed to the lifting part 200, for example, by welding or bolt connection. Of course, the clamping part 300 can also be relatively movable on the lifting part 200.

[0063] For example, refer to Figure 1 and Figure 2As shown, in some embodiments of this utility model, the pressing part 300 is slidably disposed on the lifting part 200 in a relatively vertical manner. That is, in addition to the pressing part 300 being able to move vertically relative to the moving vehicle 100 together with the lifting part 200, the pressing part 300 can also move vertically relative to the lifting part 200. An elastic part 500 is provided between the pressing part 300 and the lifting part 200. The elastic part 500 is used to apply a downward elastic force to the pressing part 300. The advantage of this arrangement is that, on the one hand, the contact between the pressing part 300 and the diesel engine casting is elastic, which can avoid excessive pressing force and damage to the diesel engine casting. On the other hand, when the lifting part 200 is adjusted downward so that the pressing part 300 abuts against the diesel engine casting and is thus limited, the setting of the elastic part 500 provides a certain buffer space. The position of the lifting part 200 does not need to be controlled too precisely to ensure that the pressing part 300 can make good contact with the diesel engine casting without excessive pressure due to excessive contact.

[0064] Reference Figures 1 to 3 As shown, in some embodiments of this utility model, the lifting part 200 includes a lifting frame 210 and a first adjusting part 220. The lifting frame 210 is vertically adjustable on the moving vehicle 100 so that the lifting part 200 can be vertically adjusted relative to the moving vehicle 100; the first adjusting part 220 is disposed on the lifting frame 210, and the first adjusting part 220 can be vertically adjusted relative to the lifting frame 210, that is, in addition to being able to move vertically synchronously with the lifting frame 210, the first adjusting part 220 can also move vertically relative to the lifting frame 210; wherein, the clamping part 400 is disposed on the lifting frame 210, the pressing part 300 is vertically slidably mounted on the first adjusting part 220, and the elastic part 500 is disposed between the first adjusting part 220 and the pressing part 300. When the first adjusting part 220 is vertically adjusted relative to the lifting frame 210, the elastic part 500 and the pressing part 300 can move vertically synchronously with the first adjusting part 220.

[0065] By adopting the above-described structural configuration, the relative height of the clamping part 300 and the clamping part 400 can be adjusted under normal conditions (i.e., when the elastic part 500 is not subjected to the reaction force of the diesel engine casting). This allows this embodiment to be applicable to diesel engine castings with various height specifications. For example, when the height of the diesel engine casting placed on the support surface 101 is large, the first adjustment part 220 can be adjusted upward relative to the lifting frame 210 to increase the height difference between the clamping part 300 and the clamping part 400 under normal conditions. As a result, when the clamping part 300 clamps the diesel engine casting, the clamping part 400 can clamp the diesel engine casting at a lower position, ensuring the positioning stability of the diesel engine casting. Similarly, when the height of the diesel engine casting placed on the support surface 101 is small, the first adjustment part 220 can be adjusted downward relative to the lifting frame 210 to decrease the height difference between the clamping part 300 and the clamping part 400 under normal conditions.

[0066] Reference Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the lifting frame 210 is provided with a vertically penetrating first threaded hole 211, and the first adjusting part 220 includes an adjusting cylinder 221. The outer peripheral wall of the adjusting cylinder 221 is provided with an external thread, and the adjusting cylinder 221 is threadedly installed in the first threaded hole 211. Thus, by rotating the adjusting cylinder 221, the first adjusting part 220 can be vertically adjusted relative to the lifting frame 210, which is very convenient. Furthermore, a knob 223 is also fixed on the adjusting cylinder 221, and the operator can rotate the adjusting cylinder 221 by rotating the knob 223, which is convenient. Specifically, the knob 223 can be welded to the outer wall of the adjusting cylinder 221.

[0067] Reference Figure 2 and Figure 4 As shown, in some embodiments of this utility model, a vertically penetrating sliding hole 222 is provided in the center of the adjusting cylinder 221, and the central axis of the sliding hole 222 is the aforementioned first axis. The pressing part 300 includes a sliding rod 310 and a pressing block 320. The sliding rod 310 slides through the sliding hole 222 to slide the pressing part 300 onto the adjusting cylinder 221. The upper and lower ends of the sliding rod 310 extend out of the adjusting cylinder 221 respectively. A limiting structure is provided at the top of the sliding rod 310. The limiting structure is used to abut against the top of the adjusting cylinder 221 to limit the downward displacement of the sliding rod 310 relative to the adjusting cylinder 221 and prevent the sliding rod 310 from detaching from the adjusting cylinder 221. The pressing block 320 is fixedly provided at the bottom end of the sliding rod 310. The pressing block 320 is used to abut against the top of the diesel engine casting to vertically limit the diesel engine casting. The elastic part 500 is configured as a compression spring, which is sleeved on the slide rod 310 and its two ends abut against the pressure block 320 and the adjusting cylinder 221 respectively, thereby applying a downward elastic force to the pressing part 300. The structure is simple and practical.

[0068] In some specific embodiments, the knob 223 is fixed to the bottom end of the adjusting cylinder 221, and the lower end face of the knob 223 is flush with the lower end face of the adjusting cylinder 221. The compression spring abuts against the adjusting cylinder 221 by abutting against the knob 223.

[0069] In some specific embodiments, the limiting structure is set as a limiting nut 330, which is threaded onto the slide bar 310; of course, the limiting structure can also be set as a pin.

[0070] Reference Figures 1 to 4As shown, in some embodiments of this utility model, the clamping part 400 includes a first screw 410 and a clamping head 420. The first screw 410 is radially threaded onto the lifting part 200 along a first axis; the clamping head 420 is disposed at one end of the first screw 410 near the pressing part 300, and the clamping head 420 is used to abut and limit the diesel engine casting. In this embodiment, by rotating the first screw 410, the clamping head 420 can move radially along the first axis, thereby clamping or releasing the diesel engine casting, which is very convenient to operate.

[0071] It is understood that the purpose of the installation form of the clamping part 300 being different from that of the clamping part 400 in this embodiment is to reduce the process of manual adjustment and simplify the operation.

[0072] Based on the above embodiments, it can be understood that, in order to facilitate the rotation of the first screw 410, an operating rod 430 is provided on the first screw 410.

[0073] In some specific embodiments, the height of the first screw 410 is lower than the height of the pressure block 320.

[0074] Reference Figure 4 As shown, in some embodiments of this utility model, the lifting part 200 includes a lifting frame 210 and a plurality of second adjusting parts 230. The lifting frame 210 is vertically adjustable and mounted on the moving vehicle 100; the second adjusting parts 230 correspond one-to-one with the clamping parts 400, and the second adjusting parts 230 are mounted on the lifting frame 210 and can be adjusted in position relative to the lifting frame 210 along the radial direction of the first axis; wherein, the first screw 410 is threadedly mounted on the second adjusting part 230. This arrangement allows the first screw 410 to move radially relative to the second adjusting part 230 along the first axis, and also to move radially together with the second adjusting part 230 along the first axis. The first screw 410 does not need to be made too long, so it can be used for different diesel engine castings with large differences in lateral dimensions.

[0075] Specifically, the second adjustment part 230 is provided with a second threaded hole 235 for installing the first screw 410.

[0076] Reference Figure 4 and Figure 5As shown, in some embodiments of this utility model, the lifting frame 210 is provided with an adjustment groove 212, which corresponds one-to-one with the second adjustment part 230. The adjustment groove 212 is radially distributed along the first axis and vertically connected. The second adjustment part 230 includes: a mounting column 231, a second screw 232 and a locking nut 233. Mounting post 231 is located on the lower side of lifting frame 210 and abuts against lifting frame 210. Second threaded hole 235 is provided on mounting post 231 for mounting first screw 410. Second screw 232 is provided at the top of mounting post 231 and passes through adjustment groove 212. Locking nut 233 is threaded on second screw 232 and located on the upper side of lifting frame 210. Locking nut 233 is used to lock and fix mounting post 231 to lifting frame 210. When the second adjustment part 230 needs to be adjusted, first loosen locking nut 233, then slide mounting post 231 along adjustment groove 212, and when it slides to the corresponding position, tighten locking nut 233 again. The operation is very convenient.

[0077] Based on the above embodiments, the second adjustment part 230 further includes a guide block 234, which is disposed on the upper end face of the mounting post 231 and embedded in the adjustment groove 212 to restrict the rotation of the mounting post 231; wherein, the second screw 232 is disposed on the upper end face of the guide block 234; by providing the guide block 234, the mounting post 231 is limited to sliding only along the extension direction of the adjustment groove 212 and will not rotate around its own center line.

[0078] It is conceivable that the vertical adjustment of the lifting unit 200 can be achieved through automatic control, for example, by controlling the lifting of the lifting unit 200 through a hydraulic cylinder, a pneumatic cylinder, or a telescopic motor; of course, it can also be achieved through manual adjustment.

[0079] For example, refer to Figure 1 and Figure 3 As shown, in some embodiments of this utility model, a vertically extending guide post 110 is provided on the support surface 101. The lifting part 200 includes a lifting frame 210, which has a vertically penetrating guide hole 213 and is slidably sleeved on the guide post 110 through the guide hole 213. A locking screw 240 is threaded on the lifting frame 210, which abuts against the peripheral wall of the guide post 110 to lock the lifting frame 210 to the guide post 110. When it is necessary to adjust the lifting frame 210 vertically, first loosen the locking screw 240, then slide the lifting frame 210 vertically, and then retighten the locking screw 240 when it slides to the corresponding position. The operation is very convenient. Specifically, a third threaded hole 214 is provided on the lifting frame 210 for installing the locking screw 240.

[0080] It is conceivable that multiple sets of guide posts 110 and guide holes 213 are provided to improve structural stability.
