[0028] Example 1

[0029] A pallet, such as Figure 1 As shown, it includes a base plate 1, a clamping block 2 and a movable mechanism. The clamping block 2 is fixedly mounted on the top of the base plate 1, and the movable mechanism is movably mounted on the top of the base plate 1. The movable mechanism cooperates with the clamping block 2 to clamp the mold placed on the top of the tray.

[0030] When using the above-described pallet, the mold is placed on base plate 1, positioned between clamping block 2 and the movable mechanism. The mold is held against clamping block 2, and the movable mechanism is adjusted so that the side of the movable mechanism closest to the mold is in close contact with the mold. The mold is then clamped together by clamping block 2 and the movable mechanism. When transporting molds of different sizes, the movable mechanism can be easily adjusted, the mold removed from base plate 1, and a new mold clamped onto base plate 1. This means that the pallet of this embodiment can easily accommodate molds of varying sizes.

[0031] like Figure 1As shown, the movable mechanism includes an OK clamp 3 and an adjustable fixed block 4. The adjustable fixed block 4 can be detachably mounted at different positions on the top of the base plate 1. The OK clamp 3 is installed on the top of the base plate 1, and the two sides of the OK clamp 3 can respectively abut against the adjustable fixed block 4 and the mold. Specifically, a guide rail 11 is provided on the top of the base plate 1, the clamping block 2 is fixed on the guide rail 11, the adjustable fixed block 4 is detachably mounted on the guide rail 11, and the OK clamp 3 is installed on the guide rail 11. During implementation, the OK clamp 3 is loosened, the mold is placed on the guide rail 11 at the bottom of the base plate 1 close to the clamping block 2, the adjustable fixed block 4 is moved on the guide rail 11, and when it is moved close to the mold, the adjustable fixed block 4 is locked. Finally, the OK clamp 3 between the adjustable fixed block 4 and the mold is locked. During the locking process, the OK clamp 3 gradually approaches the mold and cooperates with the clamping block 2 to clamp the mold.

[0032] like Figure 2 As shown, the base plate 1 is provided with several positioning posts 12 at both ends. When the pallet and the molds on it need to be transported, the pallet can be automatically moved by an AGV (Automated Guided Vehicle). The AGV has carrying arms on both sides, and the top of the carrying arms has sockets. The positioning posts 12 can fit into the sockets to position and install the pallet during the AGV's transportation.

[0033] Example 2

[0034] This embodiment is similar to the second embodiment, differing in that the clamping block 2 is fixedly mounted in the middle of the guide rail 11, and movable mechanisms are provided at each end of the guide rail 11. During operation, the two sets of movable OK clamps 3 are loosened, and the two molds are placed against either side of the clamping block 2. The two adjustable fixing blocks 4 are then moved along the guide rail 11, and finally, the two OK clamps 3 are locked. During the locking process, the adjustable fixing blocks 4 limit one side of the OK clamp 3, allowing the OK clamp 3 to gradually approach the mold and engage the clamping blocks 2 to clamp the mold. This embodiment's tray can accommodate two molds simultaneously.

[0035] The clamping block 2 can be an OK clamp 3. When in use, the OK clamp 3 as the clamping block 2 is fixed on the guide rail 11. When two molds need to be placed on the pallet at the same time, the OK clamp 3 as the clamping block 2 can be loosened and pushed to the middle of the guide rail 11 to be locked for positioning the two molds.

[0036] Example 3

[0037] A loading platform, such as Figure 2 、 Figure 3 As shown, it includes a quick-change base 5, a positioning and clamping mechanism, and the tray of embodiment 1 or embodiment 2, and the quick-change base 5 is connected to the tray through the positioning and clamping mechanism.

[0038] The above-mentioned loading and unloading platform can cooperate with the AGV to automatically load and unload pallets. When in use, the mold is installed on the pallet, and the AGV carries the pallet and automatically transports it to the top of the quick-change base 5. Then the AGV drives the pallet down, and the positioning and clamping mechanism is used to quickly connect the pallet and the quick-change base 5, and the pallet is quickly clamped and fixed on the quick-change base 5; when the pallet needs to be replaced, the pallet can also be carried by the AGV, and the positioning and clamping mechanism can be used to quickly release the pallet, which facilitates the replacement of different pallets and the automatic processing of different molds.

[0039] like Figures 2 to 3 As shown, the positioning and clamping mechanism includes a positioning clamp 7 and a connecting sleeve 6. The connecting sleeve 6 is mounted on the bottom of the pallet, and the positioning clamp 7 is mounted on the top of the quick-change base 5. The positioning clamp 7 and the connecting sleeve 6 are connected. Specifically, the connecting sleeve 6 is mounted on the base plate 1. During operation, the pallet is moved above the quick-change base 5, and the positioning clamp 7 is aligned with the connecting sleeve 6 at the bottom of the pallet. The pallet is pressed down, and the positioning clamp 7 quickly clamps the connecting sleeve 6, thereby achieving a quick connection between the quick-change base 5 and the pallet. When the positioning clamp 7 releases the connecting sleeve 6, the pallet can be removed and replaced with a new one.

[0040] like Figure 4 As shown, the positioning clamp 7 includes a base 71, a shell 72, a pushing part, a first spring 75 and a locking ball 76. The base 71 is fixedly mounted on the top of the quick-change base 5. The base 71 is provided with a cavity for an external fluid source. The shell 72 is fixedly mounted on the top of the base 71. The outer wall of the shell 72 is provided with a plurality of through holes. The locking column is located in the through holes. The pushing part is slidably installed between the shell 72 and the base 71. The top end of the first spring 75 is connected to the inner wall of the shell 72. The bottom end of the first spring 75 is connected to the pushing part. The top outer wall of the pushing part can push the locking ball 76 out of the through hole so that the locking ball 76 squeezes the connecting sleeve 6. Specifically, the fluid in the cavity is hydraulic oil. When the pallet is clamped, hydraulic oil is supplied to the cavity, and the hydraulic oil pushes the pushing part upward, and the pushing part squeezes the first spring 75 to compress the first spring 75. At the same time, the outer wall of the top of the pushing part gradually squeezes the locking bead 76 in the through hole, so that the locking bead 76 is partially pushed out of the through hole and squeezes the connecting sleeve 6, thereby achieving the locking of the positioning clamp 7 and the connecting sleeve 6; when the supply of hydraulic oil is stopped, the oil level in the cavity drops, and the pushing part moves downward under the action of the first spring 75, and the force of the pushing part on the locking bead 76 gradually decreases to disappear. At this time, the pallet can be taken out upward. In the process of taking out the pallet, the connecting sleeve 6 reacts on the locking bead 76, and the locking bead 76 returns to the through hole.

[0041] like Figure 4As shown, the pushing portion includes a push block 73 and a push rod 74. The push rod 74 is located at the top of the push block 73. The two ends of the first spring 75 are respectively connected to the inner wall of the shell 72 and the top of the push block 73. The outer diameter of the push rod 74 gradually increases from the end away from the push block 73 to the end close to the push block 73. The outer wall of the push rod 74 can contact the locking bead 76. When clamping the pallet, hydraulic oil is supplied to the cavity. The hydraulic oil pushes the push block 73 and the push rod 74 upward, causing the outer wall of the push rod 74 to contact the locking bead 76. The outer diameter of the part of the push rod 74 that contacts the locking bead 76 gradually increases, gradually pushing the locking bead 76 out of the through hole, squeezing the connecting sleeve 6, and clamping the connecting sleeve 6.

[0042] like Figure 4 As shown, the inner wall of the connecting sleeve 6 is provided with a tapered surface 61, and the inner diameter gradually increases from the bottom of the tapered surface 61 to the top of the tapered surface 61, and the locking bead 76 can abut against the tapered surface 61. When clamping the pallet, the push rod 74 slides upward along the shell 72, and the outer wall of the push rod 74 gradually squeezes the locking bead 76 outward, causing the locking bead 76 to squeeze the tapered surface 61 of the connecting sleeve 6, clamping the connecting sleeve 6 and achieving the clamping of the pallet. When the pallet is to be removed, the oil level in the cavity drops, the push block 73 and the push rod 74 move downward, and the tapered surface 61 squeezes the locking bead 76 to move into the through hole, allowing the pallet to be easily removed.

[0043] The second spring 77 is further included, and the two ends of the second spring 77 are respectively connected to the inner wall of the shell 72 and the top of the push rod 74. Figure 4 When the pallet is clamped, the push rod 74 and the push block 73 move upward, the push block 73 compresses the first spring 75, and the push rod 74 compresses the second spring 77. When the pallet is to be removed, as the oil level drops, the push block 73 and the push rod 74 move downward under the action of the first spring 75 and the second spring 77, respectively, to prevent the push rod 74 from being too tight and stuck in the housing 72, preventing normal use.

[0044] like Figure 4 As shown, it also includes a support rod 78, which is fixed to the inner wall of the shell 72, and the bottom of the support rod 78 can abut against the push block 73. When hydraulic oil is supplied to the cavity to cause the push block 73 to move upward, when the push block 73 contacts the support rod 78, the push block 73 and the push rod 74 on its top can be limited by the support rod 78 to prevent the push rod 74 from moving upward excessively and impacting the top of the shell, causing damage to the positioning clamp 7. It should be noted that the support rod 78 can also be fixed to the top of the push block 73, and the top of the support rod 78 can abut against the inner wall of the shell 72. When hydraulic oil is supplied to the cavity to cause the push block 73 to move upward, when the top of the support rod 78 contacts the inner wall of the shell 72, the push block 73 and the push rod 74 on its top can be limited by the support rod 78.

[0045] There are several positioning holes at the bottom of the tray, and several positioning pins 51 are provided at the top of the quick-change base 5. Figure 2 、 Figure 3As shown, the positioning pins 51 are matched with the positioning holes in a one-to-one manner. When clamping the pallet, the pallet can be pre-positioned by the cooperation of the positioning pins 51 and the positioning holes, ensuring that the positioning clamp 7 can be aligned with the corresponding connecting sleeve 6, which is convenient for rapid clamping of the pallet.

[0046] The loading and unloading platform in this embodiment can be used for automated mold production: molds of different shapes and sizes are installed in the standard position of the pallet through standardized pallets. After production is scheduled by MES (Manufacturing Execution System), the AGV transports the pallet point-to-point to the equipment material warehouse, and moves the pallet to the quick-change base 5 on the processing equipment. The pallet is clamped on the quick-change base 5 through the positioning and clamping mechanism. The CNC machine tool automatically aligns the tool, automatically centers the mold, automatically detects the accuracy of the processed mold, and automatically removes the waste by the chip conveyor, thereby improving the processing accuracy and smoothness required for assembly, significantly reducing the workload of relevant personnel, reducing the labor intensity of employees, and improving the production efficiency and accuracy of drainage pipe fittings molds.

[0047] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
