[0002] Aluminum alloys are among the best lightweight metal materials, possessing excellent properties such as light weight and high strength. During the processing of aluminum alloy castings, a gate removal process is required, necessitating a gate removal device. This device uses a robotic arm to drive a grinding rod at its head end to remove the gates from the casting surface. However, existing gate removal devices suffer from several drawbacks. For different product models, the installation limiting mechanism lacks a suitable quick-locking mechanism, resulting in poor installation stability and low disassembly efficiency. Furthermore, waste generated during the gate removal process tends to accumulate on the worktable surface, lacking a suitable waste collection mechanism. Additionally, waste is prone to splashing into the external environment, requiring a suitable anti-splash mechanism. Utility Model Content

[0027] Please see Figures 1-5A gate removal device for aluminum alloy castings includes a worktable 1, a fixed plate 2 on the rear side of the upper end face of the worktable 1, a robotic arm 3 on the fixed plate 2, a grinding rod 4 rotatably mounted at the head end of the robotic arm 3, a detachable limit seat 5 on the upper end face of the worktable 1, multiple limit seats 5 with different inner groove types, mounting rods 6 symmetrically mounted on the lower end face of each of the multiple limit seats 5, mounting holes 7 corresponding to two mounting rods 6 on the upper end of the worktable 1, an adjusting motor 8 rotatably mounted inside the worktable 1, an adjusting rod 9 connected to the upper end of the adjusting motor 8, a locking ring 10 mounted on the upper end of the adjusting rod 9, locking grooves 11 corresponding to the locking rings 10 on each of the multiple sets of mounting rods 6, grooves 12 corresponding to two mounting holes 7 on each locking ring 10, and a protective seat 13 slidably mounted on the top of the outer end face of the worktable 1.

[0028] In this embodiment, a suitable limiting seat 5 is selected according to the model of the casting to be de-gated. The limiting seat 5 is installed on the workbench 1. The mounting rod 6 and the mounting hole 7 are matched for installation and positioning. Before installation, the control device has its own control system. The adjusting motor 8 is started. The adjusting motor 8 drives the adjusting rod 9 and the locking ring 10 to rotate, rotating the groove 12 of the locking ring 10 to the position corresponding to the mounting hole 7. After the initial installation, the adjusting motor 8 drives the adjusting rod 9 and the locking ring 10 to rotate. The locking ring 10 and the locking groove 11 are matched to lock the installation, which facilitates the disassembly and replacement of the limiting seat 5 and improves the installation stability.

[0029] More specifically, the robotic arm 3 drives the grinding rod 4 to adjust its position, and the internal drive mechanism drives the grinding rod 4 to rotate. The grinding rod 4 removes the gate from the casting. The protective seat 13 slides up and down relative to the worktable 1 to a suitable height to protect the waste material splashed during the gate removal process and prevent it from splashing to the outside.

[0030] Please see Figures 1-3 and Figure 5 As one embodiment of the protective seat 13: guide blocks 14 are provided on the inner walls of both the left and right ends of the protective seat 13, guide grooves 15 are provided on both the left and right ends of the worktable 1 corresponding to the guide blocks 14, handles 16 are provided symmetrically on the front end of the protective seat 13, and limiting rods 17 are provided through the left and right sides of the front end of the protective seat 13. Limiting holes 18 are provided on the front end of the worktable 1 corresponding to the two limiting rods 17. Multiple limiting holes 18 are provided at intervals. Limiting plates 19 are connected to the front ends of the two limiting rods 17, and springs 20 are sleeved on the outer ends of the two limiting rods 17. The springs 20 are connected and arranged between the limiting plates 19 and the worktable 1.

[0031] Specifically, when the protective seat 13 is raised or lowered, the guide block 14 and the guide groove 15 cooperate to guide the sliding. Before sliding, the limit plate 19 is grasped, the limit rod 17 is pulled outward, the spring 20 is stretched, and it is adjusted to a suitable position. The limit plate 19 is released, the spring 20 retracts, and the limit rod 17 is reset and inserted into the limit hole 18 to achieve the limit and tightening of the height adjustment.

[0032] Please see Figures 1-3 As one method of waste collection: discharge seats 21 are provided on both the left and right sides of the upper end face of the workbench 1. The two discharge seats 21 extend outward and penetrate the left and right ends of the workbench 1 respectively. Collection seats 22 are detachably provided at the bottom of the left and right end faces of the workbench 1 corresponding to the discharge seats 21. Multiple clamping rods 23 are provided on the left and right end faces of the workbench 1. The outer ends of the multiple clamping rods 23 are provided with clamping plates 24 corresponding to the collection seats 22.

[0033] Specifically, the waste generated during the gate removal process is guided by the discharge seat 21 and falls into the collection seat 22 for collection. After a certain amount of waste is collected, the clamping rod 23 and the clamping plate 24 are rotated as a whole. The clamping plate 24 is rotated to a non-conflicting position, and the collection seat 22 is transferred to dump the waste. The dumped collection seat 22 is installed on the workbench 1. The clamping rod 23 is rotated, and the clamping rod 23 drives the clamping plate 24 to rotate. The clamping plate 24 limits and tightens the installation of the collection seat 22.

[0034] In summary, the overall equipment is in use:

[0035] When the limit seat 5 is in the installation state, select the appropriate limit seat 5 for installation according to the processing requirements. The installation rod 6 and the installation hole 7 cooperate for installation and positioning. Before installation, operate the built-in control system to start the adjustment motor 8. The adjustment motor 8 drives the adjustment rod 9 and the locking ring 10 to rotate, rotating the groove 12 of the locking ring 10 to the corresponding position of the installation hole 7. After the initial installation, the adjustment motor 8 drives the adjustment rod 9 and the locking ring 10 to rotate as a whole. The locking ring 10 and the locking groove 11 cooperate to lock the installation, which is convenient for quick disassembly and assembly and improves the installation stability.

[0036] When in the protective adjustment state, grasp the limiting plate 19 and pull the limiting rod 17 outward. The spring 20 will extend, and after the limiting rod 17 is pulled out of the limiting hole 18, grasp the handle 16 to adjust the height of the protective seat 13. The guide block 14 and the guide groove 15 cooperate to slide and guide. After the protective seat 13 is adjusted to a suitable height, release the limiting plate 19, the spring 20 will retract, and the limiting rod 17 will reset and insert into the limiting hole 18, thus achieving a tight stop for height adjustment, facilitating protective adjustment and preventing waste from splashing to the outside.

[0037] When in the waste collection state, the waste generated from the gate treatment falls onto the workbench 1. The waste is guided by the discharge seat 21 and falls into the collection seat 22 for collection. After a long period of use, a large amount of waste accumulates inside the collection seat 22. Rotate the clamp 23 and the clamp plate 24 to a non-conflicting position, disassemble the collection seat 22, and dump the waste.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
