Description

Technical Field

[0001] The utility model relates to the technical field of workpiece transfer equipment, in particular to a large-size workpiece transfer rack. Background Art

[0002] Transfer equipment is one of the commonly used equipment in the workshop, which can transfer workpieces so that the workpieces are transferred from one station to another. When transferring large-sized workpieces, such as in the production process of axle shells, the axle shells are transferred from the cleaning station to the drying station. Since the axle shells are generally large in size and heavy in weight, only a small amount of axle shells can be placed on the general transfer equipment if they cannot be stacked (for flat-plate transfer equipment, stacking will cause the axle shells to be unstable or damage the surface of the axle shells), so the transfer efficiency is low. In the prior art, in order to increase the number of placements, a vertical transfer rack can be used to place more axle shells. However, when placing them specifically, the gap between the upper and lower structures of the transfer rack is small. When the axle shells are placed on the lower layer, the upper structure will cause obstruction, which will increase the time required for placement, and ultimately the overall transfer efficiency cannot be further improved.

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] In an exemplary embodiment, Figure 1-3 As shown, the present embodiment provides a large-size workpiece transfer rack, which includes a horizontally placed mobile frame 1, mobile wheels 2 installed at the four corners of the mobile frame 1, a pair of mounting frames 3 vertically opposed and fixedly installed on the mobile frame 1, and multiple pairs of first support arms 4 arranged on the two mounting frames 3, the first support arms 4 are provided with adjustment through frames 5 arranged along the axial direction and located on the side thereof, the mounting frame 3 is also fixedly provided with a plurality of pairs of first support rods 6 and second support rods 7 located above and below corresponding to each first support arm 4 and arranged on both sides of the mounting frame 3, the mounting frame 3 is also provided with adjustment holes located between each pair of first support rods 6 and second support rods 7, and the adjustment holes and the corresponding adjustment through frames 5 are detachably locked by a first locking member 8.

[0026] In the above embodiment, the orientation of the first support arm 4 can be adjusted by adjusting the through frame 5 to avoid blocking the placement of the lower layer workpiece 9, thereby saving the time required for placement, and solving the problem in the prior art that the upper structure of the transfer rack may block the workpiece 9 (such as the axle housing) when it is placed on the lower layer, resulting in increased time consumption, so that the overall transfer efficiency cannot be further improved;

[0027] Specifically, the plurality of pairs of first support arms 4 on the same mounting frame 3 in this solution form an upper and lower support structure. When placing the lower workpiece 9, the first support arms 4 can be adjusted to be in a retracted state, that is, Figure 1 The state of the first support arm 4 of the uppermost layer on the right side is shown in FIG. 1 , so as to avoid obstruction. After placement, the first support arm 4 of the upper layer is adjusted to a supporting state, and then placed. Repeating the operation can quickly place multiple workpieces 9 on the transfer rack, thereby saving operation time and improving the overall transfer efficiency.

[0028] More specifically, the first locking member 8 is used to lock the position of the first support arm 4, mainly when the workpiece 9 is placed, that is, when the first support arm 4 is fully extended, the first locking member 8 is located at the end of the adjustment frame 5. At this time, the first locking member 8 locks the first support arm 4 on the mounting frame 3 by adjusting the frame 5. At the same time, the first support rod 6 and the second support rod 7 also play a role in strengthening the strength of the supporting structure, so that the workpiece 9 is stably supported on the transfer rack. In particular, the provision of two mounting frames 3 also increases the number of placements, and the second support rods 7 located at a higher position on the two mounting frames 3 are close to each other, thereby providing downward and upward assistance to the corresponding first support rod 6 respectively, so that the corresponding first support arm 4 can more stably support the workpiece 9; further, the first support arm 4 on the mounting frame 3 is provided on both sides thereof, so that it can be relatively more convenient to operate.

[0029] In a further exemplary embodiment, Figure 1 , 3 As shown, the mounting frame 3 is also detachably connected to a second support arm 10 located below all the first support arms 4, which is equivalent to providing an unadjustable second support arm 10 at the bottom of the transfer frame. Similarly, the mounting frame 3 is also fixedly provided with a third support rod 11 and a fourth support rod 12 located above and below the second support arm 10 and arranged on both sides of the mounting frame 3. The third support rod 11 and the fourth support rod 12 are similar to the above-mentioned first support rod 6 and the second support rod 7, and can strengthen the supporting strength of the second support arm 10 to ensure the safe transportation of the workpiece 9. Similarly, the second support arm 10 is connected to the mounting frame 3 through a second locking member 24; in a more detailed scheme, the first support arm 4 and the second support arm 10 are both provided with an upwardly bent end 13, and the bent ends 13 on the two mounting frames 3 are arranged back to back, which can play a certain blocking role on the outside.

[0030] In a more specific exemplary embodiment, Figure 1 , 2As shown, the first locking member 8 and the second locking member 24 both include a bolt 14 and a spring washer 15, that is, by loosening the bolt 14, the first support arm 4 can be adjusted (the corresponding adjustment hole is a screw hole that cooperates with the bolt 14). On the other hand, the second support arm 10 can be conveniently disassembled and maintained instead of being adjusted.

[0031] In a further exemplary embodiment, Figure 1 , 2 As shown in Figures 4 and 5, the first support arm 4 is further provided with a strip frame 16 located on its upper wall surface and arranged along its axial direction, a first cushion block 17 is further inserted into the strip frame 16, and the first cushion block 17 can also abut against the mounting frame 3, the first cushion block 17 is blocked between the workpiece 9 and the mounting frame 3 to prevent the side wall of the workpiece 9 from directly abutting against the transfer rack, and an anti-collision structure, such as a rubber anti-collision layer 18, can be added to the first cushion block 17, so that the workpiece 9 and the transfer rack can be better protected. Similarly, the second support arm 10 is also provided with a second cushion block 19 that can abut against the mounting frame 3, which is more Specifically, the first cushion block 17 includes a first plug-in section 20 and a first abutting section 21 fixedly connected and perpendicular to one end of the first plug-in section 20, and the first plug-in section 20 is inserted into the corresponding strip frame 16. Similarly, the second cushion block 19 includes a second plug-in section 22 and a second abutting section 23 fixedly connected and perpendicular to one end of the second plug-in section 22, and the second plug-in section 22 is fixedly connected to the corresponding second support arm 10. A rubber anti-collision layer 18 can be added to the first abutting section 21 and the second abutting section 23 to abut between the workpiece 9 and the mounting frame 3 to play a buffering role.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
