Description

Technical Field

[0001] This utility model relates to the field of alloy casting transfer pallet technology, and more specifically to an alloy casting multi-specification adaptive stacking pallet conversion mechanism. Background Technology

[0002] After the alloy castings are processed in a centralized manner on the production line, they need to be transferred using stacked pallets. The pallets loaded with alloy castings are transported to other production lines by manual or automated transfer vehicles.

[0003] According to the publication (announcement) number: CN212654715U, the publication (announcement) date: 2021-03-05, a foldable pallet is disclosed, including a pallet bottom frame and a foldable stop bar on it, and the stop bar is used to restrict the alloy castings placed on the pallet bottom frame.

[0004] In the prior art, including the aforementioned patent, a matching pallet mechanism is usually used during the transfer of a certain alloy casting. If the remaining production line after the transfer experiences a malfunction or problem, resulting in a decrease in the production line's processing efficiency, the alloy casting will inevitably accumulate in front of the production line. The matching pallet will also need to remain there to store the alloy casting. If the alloy casting is removed from the pallet, a new carrying and storage mechanism is required. Therefore, the number of such pallets on the transfer line will inevitably decrease, ultimately leading to the pallets being unable to meet the transfer and storage needs of the alloy casting. This also causes the previous production line, which was without malfunction or problem, to also reduce its processing efficiency, thereby reducing the overall production efficiency of the workshop. Utility Model Content

[0005] The purpose of this invention is to provide a multi-specification adaptive stacking tray conversion mechanism for alloy castings, aiming to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-specification adaptive stacking pallet conversion mechanism for alloy castings includes a pallet equipped with wheels and multiple mounting openings on the pallet. An inner rod can be detachably installed in each mounting opening, and an outer sleeve is vertically slidably fitted on the outside of the inner rod.

[0008] The outer sleeve is threaded with upper and lower arranged rotating rings, and a rubber sleeve is rotatably disposed between the two rotating rings. The rotating rings moving in opposite directions cause the rubber sleeve to bulge away from the outer sleeve.

[0009] Preferably, it further includes a locking rod hinged to the inner rod and arranged in a circular shape, wherein a fastening block for abutting against the inner wall of the outer sleeve is fixedly installed on the locking rod.

[0010] Preferably, the mounting opening has multiple locking slots, and a locking block that is inserted into the locking slots is fixedly installed at the lower end of the locking rod.

[0011] Preferably, a knob is movably sleeved on the inner rod, and a threaded ring that is threadedly connected to the mounting port is fixedly installed on the knob.

[0012] Preferably, a slip ring is fixedly installed on the inner wall of the knob, and a sliding section for the slip ring to slide is provided on the inner rod.

[0013] Preferably, a driven block is fixedly installed on the locking rod, and when the driven block slides in the inner wall of the knob, multiple locking rods are pressed together and used to unlock the inner rod.

[0014] Preferably, the knob port has a rounded opening that slides with the driven block.

[0015] Preferably, the inner rod has a triangular chamber for the locking rod to move.

[0016] Preferably, a torsion spring is provided at the hinge position of the locking rod.

[0017] Preferably, the locking rod is an aluminum alloy rod.

[0018] In the above technical solution, the multi-specification adaptive stacking pallet conversion mechanism for alloy castings provided by this utility model has the following beneficial effects: multiple outer sleeves are used to limit and block the stacked alloy castings, and then two rotating rings are rotated to squeeze the outer wall of the rubber sleeve against the edge of the stacked alloy castings, which is used to fill the gap between the outer sleeve and the edge of the stacked alloy castings, so as to achieve precise clamping and limiting of the stacked alloy castings, so that all pallets can adapt to the stacking of alloy castings of different specifications. Excess or unused pallets on other production lines can be transferred to production lines with excess capacity to maintain the existing production efficiency and avoid further reduction in the overall production efficiency of the workshop.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, a multi-specification adaptive stacking pallet conversion mechanism for alloy castings includes a pallet 1 equipped with wheels, and multiple mounting openings 11 opened on the pallet 1. An inner rod 2 can be detachably installed in the mounting opening 11, and an outer sleeve 3 is vertically slidably sleeved on the outside of the inner rod 2.

[0028] The outer sleeve 3 is threaded with upper and lower arranged rotating rings 61. A rubber sleeve 6 is rotatably arranged between the two rotating rings 61, and the rotating rings 61 moving in opposite directions cause the rubber sleeve 6 to bulge away from the outer sleeve 3.

[0029] Specifically, the tray 1 has multiple equally spaced holes to make the tray 1 frame-shaped, and the mounting opening 11 is located at the intersection of the frames.

[0030] Furthermore, the inner rod 2 is specifically an aluminum alloy rod, and the two ends of the rubber sleeve 6 are rotatably connected. Therefore, the positions of both the upper and lower ends of the rubber sleeve 6 can be changed to increase the raised gap. At the same time, since the rubber sleeve 6 has a greater thickness than the outer sleeve 3, and the rubber material is the rubber commonly used in workshops for anti-collision, buffering and support (existing technology, which will not be described in detail here), the raised rubber sleeve 6 is not easily squeezed by the reaction force of the stacked alloy castings and loses its anti-collision and limiting function.

[0031] By placing the alloy castings in a suitable position on the pallet 1 and leaving the mounting opening 11 on the outside of the alloy castings, and then fixing several inner rods 2 in the mounting opening 11, multiple outer sleeves 3 are used to limit and block the stacked alloy castings. Then, the outer sleeves 3 are pulled up to adapt to the height of the stacked alloy castings. Finally, the two rotating rings 61 are rotated to squeeze the outer wall of the rubber sleeve 6 against the edge of the stacked alloy castings to fill the gap between the outer sleeves 3 and the edge of the stacked alloy castings, so as to achieve precise clamping and limiting of the stacked alloy castings. This allows all pallets 1 to adapt to the stacking of alloy castings of different specifications. Excess or unused pallets 1 on other production lines can be transferred to production lines with excess capacity to maintain the existing production efficiency and prevent the overall production efficiency of the workshop from decreasing again.

[0032] As a further embodiment of this utility model, it also includes a locking rod 5 that is hinged to the inner rod 2 and arranged in a circular shape, and a fastening block 52 for abutting against the inner wall of the outer sleeve 3 is fixedly installed on the locking rod 5.

[0033] Specifically, in the default state, the locking rod 5 causes the end of the fastening block 52 (with a rubber pad fixedly installed to increase the friction after the position is adjusted) to press against the inner wall of the outer sleeve 3.

[0034] The locking rod 5 retracts the fastening block 52 into the inner rod 2, so that the outer sleeve 3 can be pulled up for height adjustment to accommodate the stacked alloy castings. Then, the outer sleeve 3 is secured by the fastening block 52 after it is reset, ensuring the limiting function for the stacked alloy castings.

[0035] As another embodiment provided by this utility model, the mounting port 11 is provided with a plurality of locking ports 12, and a locking block 53 that is inserted into the locking port 12 is fixedly installed at the lower end of the locking rod 5.

[0036] Specifically, the locking port 12 has a bottom in the mounting port 11 so that the inner rod 2 can be inserted into the mounting port 11 with a clearance from the ground, which facilitates the normal transport of the pallet 1.

[0037] The locking block 53, which is reset, is embedded in multiple locking slots 12 so that the inner rod 2 can be connected and installed with the mounting port 11.

[0038] As another embodiment further provided by this utility model, a knob 4 is movably sleeved on the inner rod 2, and a threaded ring 42 that is threadedly connected to the mounting port 11 is fixedly installed on the knob 4.

[0039] Specifically, the outer wall of the screw ring 42 and the inner wall of the mounting port 11 have a threaded connection effect, and both the knob 4 and the screw ring 61 have toothed recesses on their outer rings to increase manual friction.

[0040] By turning knob 4, the screw ring 42 is screwed into the mounting port 11, which applies downward pressure to the inner rod 2 until the inner rod 2 presses the locking block 53 against the bottom of the locking port 12, thus stably fixing the inner rod 2 onto the tray 1.

[0041] As another embodiment provided in this utility model, a slip ring 41 is fixedly installed on the inner wall of the knob 4, and a sliding section 21 for the slip ring 41 to slide is provided on the inner rod 2.

[0042] Specifically, slide 21 is a recess on the side wall of inner rod 2.

[0043] The knob 4 can slide on the outer wall of the inner rod 2 through the slide 21, and the rotation of the knob 4 is not disturbed. The slip ring 41 is an annular protrusion on the inner wall of the knob 4.

[0044] As a further embodiment of this utility model, a driven block 51 is fixedly installed on the locking rod 5, and when the driven block 51 slides in the inner wall of the knob 4, the multiple locking rods 5 are pressed together and used to unlock the inner rod 2.

[0045] Specifically, the inner wall of knob 4 and the outer wall of inner rod 2 slide together, and the driven block 51 in the default state extends out of the sliding section 21.

[0046] Before threaded connection, the driven block 51 is pushed by the knob 4, so that the driven block 51 is located in the retracted slide section 21, and the locking rod 5 is charged and kept closest to the axis of the inner rod 2. At this time, the fastening block 52 and the locking block 53 are retracted into the inner rod 2, so as to adjust the position of the outer tube 3 and disassemble the inner rod 2.

[0047] As another embodiment provided in this utility model, the knob 4 port is provided with a rounded opening 43 that slides with the driven block 51.

[0048] Specifically, the rounded corner treatment position at the end of the driven block 51 is always within the sliding range of the rounded corner opening 43.

[0049] By axially moving the knob 4, the rounded corner 43 actively slides the driven block 51 into the inner wall of the knob 4, making it easier for the driven block 51 to retract into the slide section 21.

[0050] As another embodiment of this utility model, the inner rod 2 is provided with a triangular cavity for the locking rod 5 to move.

[0051] Specifically, the inner wall of the triangular cavity has three holes that connect to the outside of the inner rod 2.

[0052] The triangular chamber and its holes allow the hinged locking rod 5 to move in an arc shape, and the driven block 51, fastening block 52 and locking block 53 to extend and retract.

[0053] As another embodiment provided in this utility model, a torsion spring is provided at the hinge position of the locking rod 5.

[0054] Specifically, the installation method of the torsion spring is existing technology and will not be described in detail here.

[0055] A torsion spring is used to ensure that the locking rod 5 can rotate, while the upper ends of multiple locking rods 5 will not contact each other, ensuring that the operation is carried out normally.

[0056] As another embodiment further provided in this utility model, the locking rod 5 is specifically an aluminum alloy rod.

[0057] The use of aluminum alloy makes the locking bar 5 more resistant to corrosion and wear, thus extending the service life of the component.

[0058] Working principle: By placing the alloy casting in a suitable position on the tray 1 and leaving the mounting opening 11 on the outside of the alloy casting, several inner rods 2 are inserted into the mounting opening 11. Rotating the knob 4 causes the screw ring 42 to be screwed into the mounting opening 11, thus applying downward pressure to the inner rods 2 until the inner rods 2 press the locking block 53 against the bottom of the locking opening 12, thus stably fixing the inner rods 2 on the tray 1. Multiple outer sleeves 3 limit and block the stacked alloy castings. Then, the outer sleeves 3 are pulled up to adapt to the height of the stacked alloy castings. Finally, the two rotating rings 61 are rotated to squeeze the outer wall of the rubber sleeve 6 against the edge of the stacked alloy castings to fill the gap between the outer sleeves 3 and the edge of the stacked alloy castings, thus achieving precise clamping and limiting of the stacked alloy castings. This allows all trays 1 to accommodate the stacking of alloy castings of different specifications. Excess or unused trays 1 on other production lines can be transferred to production lines with excess capacity, preventing a further decrease in the overall production efficiency of the workshop.

[0059] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
