DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Castings are metal shaped objects obtained by various casting methods, including steel castings, iron castings, copper castings, aluminum castings and other types. Castings are objects with certain shapes, sizes and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then waiting. When the casting is polished, the polished casting needs to be taken down, and then the unpolished casting can be loaded. Waiting time is too long, which affects the processing efficiency.
[0023] Example 1
[0024] Figure 1-Figure 4 This is an embodiment of the utility model: a casting grinding device, including a workbench 1, a moving mechanism 2 for reducing the waiting time for loading and unloading castings is installed on the workbench 1, and a dust cover 3 is installed on the workbench 1, holes are opened on both sides of the dust cover 3, and a grinding mechanism 4 is installed on the dust cover 3, and a clamping mechanism 5 for fixing the casting is arranged under the grinding mechanism 4, and the moving mechanism 2 drives the base 204 to move back and forth and left and right, so as to reasonably utilize the grinding time, complete the preparation work before grinding, and improve the grinding processing efficiency.
[0025] Reference Figure 1-3As shown, the moving mechanism 2 includes a support plate and a mounting seat respectively fixed on the lower end surface of the workbench 1, a screw rod 201 and a limit rod 202 are rotatably connected between the mounting seat and the support plate, a nut seat 203 is mounted on the screw rod 201, the nut seat 203 is slidably connected to the limit rod 202, and a connecting block is fixed on the nut seat 203, a base 204 slidably connected to the workbench 1 is fixed on the connecting block, grooves for placing castings are respectively provided on the left and right sides of the base 204, a motor 205 for driving the screw rod 201 to rotate is installed on the mounting seat, two rows of rollers are fixed on the lower end surface of the base 204, two tracks for use with the rollers are provided on the workbench 1, and a long groove adapted to the connecting block is provided on the workbench 1. Specifically, when the casting is being polished, at the beginning, the casting is first placed in the groove on the right side of the base 204, and the motor 205 is started to rotate forward through the controller to drive the screw rod 201 to rotate and drive the nut seat 203 and the base 204 to move to the right. The distance of each movement is set in advance. At this time, the casting on the right side of the base 204 is directly below the polishing disc, and the electric push rod 501 pushes the clamping block to fix the casting. Then the cylinder 401 pushes the push rod 402 to move downward. After reaching the moving position, the grinder 403 is started to polish the casting. During the polishing process, the staff on the left side of the workbench 1 can put the next polished casting into the groove on the left side of the base 204 first. After the polishing is completed, the staff can control The controller controls the motor 205 to continue to rotate forward, driving the base 204 to move to the far right. At this time, the casting on the left side of the base 204 is directly under the grinding disk for grinding; at this time, the casting on the right side of the base 204 moves to the outside of the dust cover 3, and the staff on the right side of the workbench 1 can unload the casting on the right side of the base 204, and then put the unground casting on the base 204 on the right; when the casting on the left side of the base 204 is polished, similarly, the controller is used to start the motor 205 to reverse and move to the left. This mechanism can realize double-station processing. During grinding, the polished casting on the other side of the base 204 is unloaded, and the unground casting is loaded, thereby reducing the waiting time for loading and unloading and speeding up work efficiency.
[0026] In this embodiment, Figure 2 As shown, the grinding mechanism 4 includes a cylinder 401 fixed on the dust cover 3, a push rod 402 is fixed on the telescopic end of the cylinder 401, a grinder 403 is fixedly installed on the push rod 402, a grinding disc is fixed on the grinder 403, and a dustproof mechanism 6 is installed on the push rod 402 for automatically closing the hole during grinding.
[0027] In this embodiment, Figure 2As shown, the clamping mechanism 5 includes two electric push rods 501 fixed on the workbench 1, the telescopic ends of the electric push rods 501 are fixed with clamping blocks, and the electric push rods 501 are installed inside the dust cover 3. A controller is installed on the workbench 1, and the motor 205, the cylinder 401, the electric push rods 501, and the grinder 403 are all electrically connected to the controller.
[0028] During the grinding process, if the hole is always open, dust will fly. If workers inhale the dust, it will cause harm to their bodies and affect their health. Through the dust prevention mechanism 6, during grinding, the dust shield plate 602 moves down with the push rod 402 and automatically closes the hole. After the grinding is completed, the dust shield plate 602 moves up with the push rod 402 and automatically opens the hole.
[0029] Example 2
[0030] Based on Example 1, Figure 1 and Figure 4 As shown, the dustproof mechanism 6 includes a bracket 601 fixed on the push rod 402, and dust shields 602 slidably connected to the side walls of the dust cover 3 are fixed on both sides of the bracket 601, and a T-shaped slider is fixed on the dust plate, and a slide groove used in conjunction with the slider is provided on the side wall of the dust cover 3. During grinding, the push rod 402 needs to be driven downward by the cylinder 401, and after reaching a suitable position, grinding is performed. When the push rod 402 moves downward, the bracket 601 is driven downward, so that the dust shield 602 can block the hole on the dust cover 3, so that iron filings and dust can be prevented from flying out when grinding begins. After grinding is completed, the push rod 402 moves upward, and the dust shield 602 is moved upward at the same time, so as not to delay the discharge and feeding of the casting on the base 204, and to ensure the health and safety of the workers. In addition, a vacuum cleaner can also be installed on the dust cover 3 to vacuum dust while grinding.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
