Description

Technical Field

[0001] The utility model relates to the technical field of casting grinding, in particular to a casting grinding device. Background Art

[0002] Castings are metal objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with certain shapes, sizes and properties. Grinding equipment is usually required for processing during the production process of castings.

[0003] At present, traditional grinding equipment usually needs to adopt grinding methods with different inclination angles when in use. The grinding roller can change its contact surface with the casting by tilting at different angles. However, during grinding, the staff needs to adjust the inclination angle of the grinding roller in time to avoid excessive grinding of the casting. However, this method is more cumbersome to operate and affects the grinding efficiency of the casting. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] Example

[0026] Reference Figure 1-4 As shown, a casting grinding device comprises a grinding plate 1 and a bracket 2 fixed on the top of the grinding plate 1, a bottom plate 311 is fixed on the top of the bracket 2, a hole 313 is opened inside the bottom plate 311, a lifting rod 312 is passed through the hole 313, a top plate 314 is fixed on the top of the lifting rod 312, a fixing block 316 is fixed on the bottom end, a spring 317 is wound around the outer wall of the lifting rod 312, one end of the spring 317 is connected to the fixing block 316, and the other end is connected to the bottom plate 311. By pulling the top plate 314 upward to drive the lifting rod 312 to slide along the inner wall of the hole 313, the spring 317 is driven to compress, and the staff can place the casting on the bottom plate 311. When the top plate 314 is released, the lifting rod 312 and the top plate 314 are driven to rebound under the elasticity of the spring 317, and a pad 315 is fixed on the bottom end of the top plate 314, and the pad 315 is arranged corresponding to the bottom plate 311. At this time, the top plate 314 drives the pad 315 to press the casting. The pad 315 can be made of rubber material, which has a good anti-slip effect and can improve the anti-falling effect of the equipment.

[0027] The outer wall of the fixed block 316 is provided with an inclined surface, which is distributed from bottom to top away from the middle position of the bracket 2. A movable rod 318 runs through the side wall of the bracket 2. A push plate 319 is fixed to the end of the movable rod 318 extending outside the bracket 2, and a connecting block 321 is fixed to the end located inside the bracket 2. The inner wall of the connecting block 321 is rotatably connected to a roller 320, and the roller 320 can roll on the inner wall of the connecting block 321. When the push plate 319 is pushed, the movable rod 318, the connecting block 321 and the roller 320 can be driven to move. The roller 320 will conflict with the inclined surface of the fixed block 316 and drive the roller 320 to rotate, which can resist the upward component of force on the fixed block 316, presenting a Figure 1-4 Status shown.

[0028] A first fixing plate 411 is fixed to the top of the bracket 2, and a second fixing plate 412 is rotatably connected to the outer wall of the first fixing plate 411. A motor compartment 413 is fixed to the end of the second fixing plate 412 away from the first fixing plate 411. A grinding motor 414 is installed inside the motor compartment 413. A grinding roller 423 is connected to the output end of the grinding motor 414. After the grinding motor 414 is working, it can drive the grinding roller 423 to rotate, thereby grinding the outer wall of the clamped casting. By pulling the motor compartment 413 upward, the grinding motor 414 and the second fixing plate 412 can be driven to rotate about the axis of the connection between the first fixing plate 411 and the second fixing plate 412.

[0029] A support plate 415 is fixed to the top of the bracket 2, a threaded sleeve 416 is fixed to the outer wall of the support plate 415, an adjusting screw 417 is threadedly connected to the inner wall of the threaded sleeve 416, and a movable plate 418 is rotatably connected to the bottom end of the adjusting screw 417, and the bottom end of the movable plate 418 is movably connected to the top of the motor compartment 413. By rotating the adjusting screw 417, the outer thread of the outer wall of the adjusting screw 417 will be connected to the inner thread of the threaded sleeve 416, driving the adjusting screw 417 to drive the movable plate 418 to move up and down in an inclined manner, and drag the motor compartment 413 and the grinding motor 414 to swing up and down, so as to achieve the effect of controlling the multi-angle grinding of the grinding roller 423. The top of the motor compartment 413 is provided with a sliding groove 421, and a sliding block 420 is slidably connected inside the sliding groove 421. The top of the sliding block 420 is hinged to the movable plate 418 through a hinge rod 419. When the adjusting screw 417 moves, the hinge rod 419 is driven to rotate, and the sliding block 420 is pushed to slide on the inner wall of the sliding groove 421, thereby rotating the motor compartment 413 up and down. A limiting groove 422 is provided on the inner wall of the sliding groove 421, and the outer wall of the sliding block 420 is clamped in the limiting groove 422. The setting of the limiting groove 422 can achieve a better limiting purpose, ensuring that the sliding block 420 will not fall off from the inside of the sliding groove 421.

[0030] Working principle: When it is needed, push the push plate 319 to move the movable rod 318, the connecting block 321 and the roller 320 toward the inside of the bracket 2. At this time, the roller 320 contacts the fixed block 316 and drives the fixed block 316, the lifting rod 312 and the top plate 314 to rise, placing the casting on the top of the bracket 2. Then release the push plate 319, drive the fixed block 316 to rebound under the elasticity of the spring 317, and drive the top plate 314 and the pad 315 to press down, and the pad 315 presses the casting to achieve a locking effect.

[0031] When it is necessary to adjust the rotation of the grinding roller 423, the adjusting screw 417 is rotated to drive the movable plate 418 to tilt and move under the action of the inner thread of the inner wall of the threaded sleeve 416, and drive the hinged rod 419 to rotate, pushing the sliding block 420 to slide on the inner wall of the sliding groove 421, driving the motor compartment 413 and the grinding motor 414 to rotate about the axis between the first fixed plate 411 and the second fixed plate 412, thereby achieving the effect of adjusting the grinding angle of the grinding roller 423.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
