[0003] The current grinding process for castings still has the following shortcomings: existing clamping devices are mainly designed for castings of fixed size. When encountering ring-shaped castings of different sizes that need to be ground simultaneously, it is not convenient to operate them. Multiple clamping devices of fixed size are required for fixation, which has certain limitations. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a casting grinding clamping fixture.

The output shaft of the second motor passes through the fixed frame and is keyed to a rotating shaft. One end of the rotating shaft is rotatably connected to a turntable, and the turntable is fixed to the inner wall of one side of the fixed frame. An electric push rod is bolted to one side of the turntable. The moving end of the electric push rod is rotatably connected to a clamping ring through a rotating groove, and the clamping ring is sleeved on the outer circumference of the rotating shaft. A fixed plate is welded to the other end of the rotating shaft. Multiple clamping plates are sleeved on the outer circumference of the rotating shaft, and the multiple clamping plates are all located between the fixed plate and the clamping ring. A telescopic rod is bolted to one side of the turntable, and one end of the telescopic rod is rotatably connected to the clamping ring.

Detailed Implementation

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Reference Figures 1-3 A casting grinding clamping fixture includes a fixed frame 5. Two mounting brackets 4 are bolted to one outer wall of the fixed frame 5. A first motor 2 and a second motor 3 are bolted to the top outer walls of the two mounting brackets 4 respectively. The output shaft of the first motor 2 passes through the fixed frame 5 and is keyed to a grinding roller 13. The output shaft of the second motor 3 passes through the fixed frame 5 and is keyed to a rotating shaft 7. One end of the rotating shaft 7 is rotatably connected to a turntable 6, and the turntable 6 is fixed to one inner wall of the fixed frame 5. An electric push rod 18 is bolted to one side of the turntable 6. The moving end of the electric push rod 18 is rotatably connected to a clamping ring 19 through a rotating groove, and the clamping ring 19 is sleeved on the outer circumference of the rotating shaft 7. A fixed plate 14 is welded to the other end of the rotating shaft 7. Multiple clamping plates 15 are sleeved on the outer circumference of the rotating shaft 7. The plates 15 are located between the fixed plate 14 and the clamping ring 19. One side of the turntable 6 is fixed with a telescopic rod 17 by bolts, and one end of the telescopic rod 17 is rotatably connected to the clamping ring 19. In use, the casting is placed between two adjacent clamping plates 15, and then the electric push rod 18 is started. The electric push rod 18 pushes the clamping ring 19 to slide on the rotating shaft 7, thereby squeezing the clamping plates 15 to clamp the casting. The first motor 2 and the second motor 3 are started. The first motor 2 drives the grinding roller 13 to rotate, and the second motor 3 drives the rotating shaft 7, the clamping plate 15, and the casting to rotate, so that the casting comes into contact with the grinding roller 13, thereby completing the grinding of the outer surface of the casting. Since the clamping plates 15 are movable, they can clamp castings of different thicknesses, thereby meeting the clamping requirements of different castings and improving the applicability of the equipment.

[0023] In this invention, the top of the fixing frame 5 is hinged to a protective cover 1, and the protective cover 1 is fixed to the fixing frame 5 by a snap fastener. When placing castings, the protective cover 1 is opened to place the castings between the clamping plates 15. This prevents sparks from flying during the grinding of castings, improving the safety of the device. The top of the protective cover 1 is arc-shaped, allowing foreign objects to slide directly off the arc-shaped top surface, preventing accumulation. Slide rails 9 are bolted to the inner walls of both sides of the fixing frame 5. A collection box 10 is slidably connected to the bottom of the slide rails 9, and the collection box 10 is fixed to the fixing frame 5 by a pin. This allows for the collection of debris generated during grinding and the unified processing of the collected debris. The four corners of the bottom of the collection box 10 are secured by… The road bolt is fixed with casters 12 to reduce the friction between the collection box 10 and the ground, allowing the collection box 10 to move easily. A handle 11 is fixed to one outer wall of the collection box 10 by bolts, making it easy to pull the collection box 10 to move. A placement groove is opened on one outer wall of the fixing frame 5, and an observation window 8 is fixed in the placement groove by bolts. The grinding status of the casting can be observed through the observation window 8 for real-time monitoring. Magnets 16 are glued to both sides of multiple clamping plates 15. Two magnets 16 on the same clamping plate 15 attract each other, and two magnets 16 on opposite sides of two adjacent clamping plates 15 attract each other. When the casting is placed between two clamping plates 15, the two adjacent magnets 16 will clamp the casting, which will help fix the casting and prevent it from falling, thus improving the stability of the casting.

[0024] Working principle: In use, open the protective cover 1 and place the casting between the clamping plates 15. The two adjacent magnets 16 will clamp the casting, providing auxiliary fixation and preventing it from falling. Then, start the electric push rod 18, which pushes the clamping ring 19 to slide on the rotating shaft 7, thereby squeezing the clamping plates 15 to hold the casting. Close the protective cover 1 and start the first motor 2 and the second motor 3. The first motor 2 drives the grinding roller 13 to rotate, and the second motor 3 drives the rotating shaft 7, clamping plates 15, and casting to rotate, so that the casting comes into contact with the grinding roller 13, thereby completing the grinding of the outer surface of the casting. The grinding debris will fall into the collection box 10. When the collection box 10 is full of debris, pull the collection box 10 out by the handle 11 to remove the debris. After removing the debris, the collection box 10 is reset. Since the clamping plates 15 are movable, they can clamp castings of different thicknesses, thus meeting the clamping requirements of different castings and improving the applicability of the equipment.
