Description
Technical Field
[0001] This utility model relates to the field of crystal growth equipment technology, specifically a conical crucible hinged forklift adapter fixture. Background Technology
[0002] Aluminum alloy is the preferred material for large equipment fixtures due to its lightweight and high rigidity. The hinge-linked opening and closing structure can improve the fixture's adaptability to irregular workpieces. Among these, the standardized interface design of forklift legs is the key to realizing automated logistics.
[0003] Traditional crucible fixtures used for crystal growth mostly adopt rigid fixed structures, which are poorly adapted to ultra-large crucibles (≥600mm), easily leading to stress concentration and deformation. Existing forklift-compatible fixtures lack round hole avoidance design, causing interference with the crucible spindle support sleeve, affecting loading and unloading accuracy, and are no longer applicable.
[0004] Manual clamps are inefficient to operate and lack a quick locking mechanism, making them unsuitable for continuous production.
[0005] Now, a novel conical crucible hinged forklift adapter fixture is proposed to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a conical crucible hinged forklift adapter fixture to solve the problem of inconvenience in clamping crucibles mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a conical crucible hinged forklift adapter clamp, comprising a pallet support and a left half of the pallet, wherein the left half of the pallet is movably connected to the rear left side of the top of the pallet support, and the right half of the pallet is movably connected to the rear right side of the top of the pallet support; a balance bar is horizontally fixed at the center of the rear of the pallet support; smooth blocks are respectively fixed to the rear of the left half of the pallet and the right half of the pallet; positioning plates are respectively fixed to the front ends of the left half of the pallet and the right half of the pallet, and connecting pins are horizontally threaded between the positioning plates; a wedge-shaped insert plate is attached to the front surface of the right half of the pallet; a crucible body is placed above the left half of the pallet and the right half of the pallet, and an anti-slip layer is fixed around the lower outer perimeter of the crucible body.
[0008] As a further technical solution of this utility model, the diameter of the slot of the positioning piece matches the connecting pin, and the wedge-shaped insert is longitudinally inserted into the connecting pin.
[0009] As a further technical solution of this utility model, holes are respectively provided at the front right of the top of the tray support and at the front of the right half of the tray, and positioning pins are movably inserted between the holes.
[0010] As a further technical solution of this utility model, the positioning pin enters and exits the hole from the top and bottom, and the positioning pin and the hole are on the same vertical plane.
[0011] As a further technical solution of this utility model, the center of the left half and the right half of the tray are respectively provided with slots, and a sleeve block is inserted and fixed in the slot. A support column is fixedly connected to the bottom of the sleeve block, and a base plate is fixed below the support column. A groove is provided at the top of the sleeve block, and the bottom of the crucible body is embedded in the groove.
[0012] As a further technical solution of this utility model, the diameter of the sleeve block matches the inner diameter of the slot, and the bottom diameter of the crucible body matches the inner diameter of the groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the conical crucible hinged forklift adapter not only makes it easy to open or close the clamp and lock the position of the crucible, but also supports the crucible and the clamp.
[0014] (1) The left half of the tray is movably connected to the left rear of the top of the tray support, and the right half of the tray is movably connected to the right rear of the top of the tray support. The left half and the right half of the tray are respectively fitted onto the two pins of the tray support for fixation. The left half and the right half of the tray can rotate around the two pins at the rear of the tray support at a small angle of 0-20°. Under the rotation of the smooth block, the left and right halves are opened and closed. The positioning pin at the front is connected to the positioning plate, and then the wedge plate is inserted longitudinally for locking. The crucible body can be connected and fixed. The rear end of this fixture adopts a symmetrical double hinge structure with an adjustable opening and closing angle of 0-50°. It can be opened and closed quickly by manual drive. The opening and closing force is 30≤N, which reduces the difficulty of operation.
[0015] (2) A positioning pin is inserted between the right half of the tray and the hole. Rotate the right half of the tray so that the pin hole on it is concentric with the pin hole of the tray support. Then insert the positioning pin to fix the right half of the tray. Rotate the left half of the tray so that the interface between the left and right halves coincides. At this time, the left and right halves form a circle. Then insert the wedge plate into the connecting pin to complete the closure of the clamp. To open the clamp, simply reverse the operation.
[0016] (3) By setting slots at the center of the left half and the right half of the tray respectively, adjust the fork teeth of the stacker to a suitable width so that they can be inserted into the slots of the tray support. At this time, the left and right halves are in an open state. Raise the stacker to a suitable height and move the stacker so that the groove of the block at the center of the left and right trays is approximately coaxial with the center line of the crucible body. Merge the left and right halves, and then finely adjust the position of the stacker so that the center of the left and right trays is collinear with the center of the crucible body. Slowly lower the crucible body so that it sits in the groove of the clamp. Then the crucible spindle continues to descend, leaving the crucible body to a suitable position. Move the stacker so that the crucible and clamp leave the support of the crystal growth equipment and slowly fall down, thus completing the unloading action. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5An embodiment of this utility model provides: a conical crucible hinged forklift adapter clamp, including a pallet support 3 and a left half of the pallet 2. The left half of the pallet 2 is movably connected to the rear left side of the top of the pallet support 3, and the right half of the pallet 9 is movably connected to the rear right side of the top of the pallet support 3. A balance bar 16 is horizontally fixed at the center of the rear of the pallet support 3. Smooth blocks 15 are fixed to the rear of the left half of the pallet 2 and the right half of the pallet 9, respectively. Positioning pieces 4 are fixed to the front ends of the left half of the pallet 2 and the right half of the pallet 9, and connecting pins 7 are horizontally threaded between the positioning pieces 4. A wedge-shaped insert plate 11 is attached to the front surface of the right half of the pallet 9. A crucible body 1 is placed above the left half of the pallet 2 and the right half of the pallet 9, and an anti-slip layer 10 is fixed around the lower outer perimeter of the crucible body 1.
[0025] The diameter of the slot of the positioning piece 4 matches that of the connecting pin 7, and the wedge-shaped insert 11 is longitudinally inserted into the connecting pin 7;
[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the left half 2 and the right half 9 of the tray are respectively fitted onto the two pins of the tray support 3 for fixation. The left half 2 and the right half 9 of the tray can rotate at a small angle of 0-20° around the two pins behind the tray support 3. Under the rotation of the smooth block 15, the left and right halves are opened and closed. The positioning pin 8 in front is connected to the positioning piece 4, and then the wedge-shaped insert 11 is inserted longitudinally for locking, so that the crucible body 1 can be overlapped and fixed.
[0027] Holes 13 are provided at the front right of the top of the tray support 3 and at the front of the right half of the tray 9, respectively. A positioning pin 8 is movably inserted between the holes 13. The positioning pin 8 moves in and out of the holes 13, and the positioning pin 8 and the holes 13 are on the same vertical plane.
[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, rotate the right half 9 of the tray so that the pin hole 13 on it is concentric with the pin hole 13 of the tray support 3, and then insert the positioning pin 8 to fix the right half 9 of the tray. Rotate the left half 2 of the tray so that the interface between the left and right halves coincides. At this time, the left and right halves form a circle. Then insert the wedge plate 11 into the connecting pin 7 to complete the closure of the clamp.
[0029] The left half 2 and the right half 9 of the tray are respectively provided with slots 17, and a sleeve block 14 is inserted and fixed in the slot 17. The bottom of the sleeve block 14 is fixedly connected to the support column 5, and the bottom plate 6 is fixed below the support column 5. The top of the sleeve block 14 is provided with a groove 12, and the bottom of the crucible body 1 is embedded in the groove 12. The diameter of the sleeve block 14 matches the inner diameter of the slot 17, and the bottom diameter of the crucible body 1 matches the inner diameter of the groove 12.
[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, adjust the stacker fork teeth to a suitable width so that they fit snugly into the slots 17 of the pallet bracket 3. At this point, the left and right halves are in an open state, as shown. Figure 2 As shown, raise the stacker to a suitable height and move the stacker so that the groove 12 of the sleeve block 14 at the center of the left and right trays is approximately coaxial with the center line of the crucible body 1. Merge the left and right halves, then fine-tune the position of the stacker so that the center of the left and right trays is collinear with the center of the crucible body 1. Slowly lower the crucible body 1 so that it sits in the groove 12 of the fixture. Then the crucible spindle continues to descend, leaving the crucible body 1 to a suitable position. Move the stacker so that the crucible and fixture leave the support column 5 of the crystal growth equipment.
[0031] Working principle: In use, the left half 2 and right half 9 of the tray are first fixed by fitting them onto the two pins of the tray support 3. The left half 2 and right half 9 can rotate at a small angle of 0-20° around the two pins behind the tray support 3. With the rotation of the smooth block 15, the left and right halves open and close. The positioning pin 8 at the front connects to the positioning piece 4, and then the wedge-shaped insert 11 is inserted longitudinally for locking, allowing the crucible body 1 to overlap and be fixed. During this process, the right half of the tray also needs to be rotated. Part 9 is aligned with the pin holes 13 of the pallet support 3. Then, the positioning pin 8 is inserted to fix the right half 9 of the pallet. The left half 2 of the pallet is rotated so that the interfaces of the left and right halves coincide, forming a circle. The wedge-shaped insert 11 is then inserted into the connecting pin 7, completing the clamp's closure. To open the clamp, the operation is reversed. Finally, the stacker fork teeth are adjusted to a suitable width so that they fit perfectly into the slots 17 of the pallet support 3. At this point, the left and right halves are in an open state. Figure 2As shown, raise the stacker to a suitable height and move it so that the groove 12 of the sleeve block 14 at the center of the left and right trays is approximately coaxial with the center line of the crucible body 1. Merge the left and right halves, then fine-tune the position of the stacker so that the center of the left and right trays is collinear with the center of the crucible body 1. Slowly lower the crucible body 1 so that it sits in the groove 12 of the clamp. Then the crucible spindle continues to descend, leaving the crucible body 1 to a suitable position. Move the stacker so that the crucible and clamp leave the support column 5 of the crystal growth equipment and slowly fall down, thus completing the unloading operation.
