Description

Technical Field

[0001] The present invention relates to the technical field of production and processing of cast steel parts, and specifically to a surface grinding device for the production and processing of cast steel parts. Background Art

[0002] Cast steel parts refer to parts made of cast steel, which are similar in performance to cast iron but have better strength than cast iron. Cast steel parts are widely used in various industries due to their excellent performance and have become an indispensable important component part of various machines. Cast steel refers to steel specifically used for manufacturing steel castings. When the strength requirements of the casting are relatively high and cast iron cannot meet the requirements, cast steel should be used. However, the fluidity of the molten steel of cast steel is not as good as that of cast iron. Therefore, the thickness of the casting structure cannot be too small, and the shape should not be too complex. Controlling the silicon content at the upper limit can improve the fluidity of the molten steel. Cast steel can be divided into general engineering cast steel, cast steel for welded structures, stainless steel cast steel, and heat-resistant steel cast steel according to varieties and uses. When producing and processing cast steel parts, grinding equipment is used to grind and remove burrs or surplus materials on the whole body of the cast steel parts to improve the overall smoothness of the surface of the cast steel parts and ensure that the size and shape meet the production standards.

[0003] The existing devices cannot fix the workpiece well during the grinding process, and the workpiece is prone to falling off. Moreover, they cannot adapt to tubular workpieces with different diameters, and the adaptability of the devices is relatively low. Summary of the Invention

[0021] The present invention provides a surface grinding device for the production and processing of steel castings. It has the following beneficial effects:

[0022] 1. For this surface grinding device for the production and processing of steel castings, through the installation of the supporting device, the electric telescopic rod pushes the first belt piston to move. When the first belt piston moves, it squeezes the hydraulic oil inside the hydraulic pipe, and the hydraulic pressure is squeezed into the extension sleeve. The hydraulic oil entering the extension sleeve pushes the second belt piston, and the second belt piston pushes the support cylinder to move until the support cylinder presses tightly against the inner wall of the workpiece.

During the grinding process, the workpiece can be fixed to avoid the workpiece falling off, and it can adapt to tubular workpieces with different diameters, improving the adaptability of the device.

[0023] 2. For this surface grinding device for the production and processing of steel castings, through the installation of the clamping plate, pull the clamping plate, and drive the sliding rod to slide out of the sliding sleeve through the clamping plate until the clamping plate is pulled to both ends of the workpiece. Then rotate the clamping plate and turn the clamping plate to one end of the workpiece. The two ends of the workpiece can be clamped through the clamping plates at both ends of the support cylinder. Subsequently, start the rotating motor. The rotating motor drives the hydraulic pipe to rotate through the rotating column. The hydraulic pipe can drive the support cylinder to rotate through the second belt piston. The support cylinder drives the clamped workpiece to rotate through the clamping plate, and the outer sides of all positions of the workpiece can be ground, while maintaining the stability of the workpiece during rotation.

[0024] 3. For the surface grinding equipment for the production and processing of steel castings, through the installation of the pressing device, after the electric push rod extends, it pushes the positioning bracket to slide upward. The positioning bracket drives the arc-shaped pressing plate to move. The arc-shaped pressing plate drives the pressing column to press tightly against the outer wall of the workpiece, continuously pushes the workpiece, and drives the rotating motor to move upward, causing the limit block to slide along the limit sliding frame until the outer wall of the workpiece contacts the bottom of the grinding head, always pressing the workpiece tightly against one side of the grinding head. When the rotating motor drives the workpiece to rotate, the second electric slide rail is turned on. The second electric slide rail drives the arc-shaped plate to move through the movable plate. The arc-shaped plate drives the sponge pad to move away from the bottom of the pressing column. At this time, the pressing column is no longer blocked by the sponge pad, and the workpiece can drive the pressing column to rotate when rotating, reducing the friction force in contact with the workpiece and avoiding wear when the workpiece rotates. Moreover, when rotating the workpiece, the distance between the workpiece and the grinding head is maintained, avoiding different grinding pressures on various parts of the workpiece by the grinding head during the rotation of the workpiece.

[0025] 4.

[0052] During use, the worker sleeved the tubular workpiece to be polished onto the support cylinder 510, turned on the electric telescopic rod 57. The electric telescopic rod 57 pushed the first belt rod piston 56 to move. When the first belt rod piston 56 moved, it extruded the hydraulic oil inside the hydraulic pipe 55, and the hydraulic pressure was squeezed into the extension sleeve 58. The hydraulic oil entering the extension sleeve 58 pushed the second belt rod piston 59, and the second belt rod piston 59 pushed the support cylinder 510 to move until the support cylinder 510 was tightly pressed against the inner wall of the workpiece. Since there are multiple groups of support cylinders 510, the inner wall of the workpiece can be supported by the multiple groups of support cylinders 510. Subsequently, the driving motor 3 was turned on to drive the grinding head 4 to rotate, and the outer wall of the workpiece could be polished by the grinding head 4. During the grinding process, the workpiece could be fixed to avoid the workpiece from falling off, and it could adapt to tubular workpieces with different diameters, improving the adaptability of the device.

[0053] After the worker sleeved the workpiece onto the support cylinder 510, the clamping plate 515 was pulled. The sliding rod 514 was driven by the clamping plate 515 to slide out of the sliding sleeve 511 until the clamping plate 515 was pulled to both ends of the workpiece. Then the clamping plate 515 was rotated, and the clamping plate 515 was rotated to one end of the workpiece.

At this time, the pressing column 65 is no longer blocked by the sponge pad 610, and the workpiece can drive the pressing column 65 to rotate when rotating, reducing the friction force in contact with the workpiece and avoiding wear when the workpiece rotates. And keep the distance between the workpiece and the grinding head 4 when rotating the workpiece to avoid different grinding pressures on each part of the workpiece by the grinding head 4 during the rotation of the workpiece.

[0055] For the second embodiment, please refer to Figures 1 - 9 , the present invention provides a technical solution: on the basis of the first embodiment, the cleaning device 69 includes a brush roller 691. Both ends of the brush roller 691 are fixedly connected with limit brackets 692 through brackets. One side of the limit bracket 692 is rotatably connected with a positioning rod 693 through a bearing. An extension plate 694 is fixedly connected to the outside of the positioning rod 693. A compression spring 695 is fixedly connected to one side of the extension plate 694. A fixing plate 696 is fixedly connected to the side surface of the limit bracket 692.

[0056] The side of the extension plate 694 away from the positioning rod 693 is fixedly connected to the top of the arc-shaped pressing plate 63. There are two groups of extension plates 694. The end of the compression spring 695 away from the extension plate 694 is fixedly connected to the side surface of the fixing plate 696.

[0057] During use, when the arc-shaped pressing plate 63 moves, it drives the positioning rod 693 to move through the extension plate 694. The positioning rod 693 drives the brush roller 691 to press tightly against the outer wall of the workpiece through the limit bracket 692. When the workpiece rotates and passes through the brush roller 691, the brush roller 691 can clean the outer wall of the workpiece to avoid grinding debris falling on the outer wall of the workpiece and affecting the workpiece processing.

[0058] Working principle: The worker slips the tubular workpiece to be polished onto the support cylinder 510, turns on the electric telescopic rod 57, and pushes the first belt rod piston 56 to move through the electric telescopic rod 57. When the first belt rod piston 56 moves, it squeezes the hydraulic oil inside the hydraulic pipe 55, and the hydraulic pressure is squeezed into the extension sleeve 58. The hydraulic oil entering the extension sleeve 58 pushes the second belt rod piston 59, and the second belt rod piston 59 pushes the support cylinder 510 to move until the support cylinder 510 abuts tightly against the inner wall of the workpiece. Since there are multiple groups of support cylinders 510, multiple groups of support cylinders 510 can be used to support the inner wall of the workpiece. Subsequently, the driving motor 3 is turned on to drive the grinding head 4 to rotate, and the grinding head 4 can be used to polish the outer wall of the workpiece. During the polishing process, the workpiece can be fixed. After the worker slips the workpiece onto the support cylinder 510, the clamping plate 515 is pulled, and the sliding rod 514 is driven by the clamping plate 515 to slide out of the sliding sleeve 511 until the clamping plate 515 is pulled to both ends of the workpiece. Then the clamping plate 515 is rotated and turned to one end of the workpiece, and the two ends of the workpiece can be clamped by the clamping plates 515 at both ends of the support cylinder 510. Subsequently, the rotating motor 53 is turned on, and the rotating motor 53 drives the hydraulic pipe 55 to rotate through the rotating column 54. The hydraulic pipe 55 can drive the support cylinder 510 to rotate through the second belt rod piston 59, and the support cylinder 510 drives the clamped workpiece to rotate through the clamping plate 515. The electric push rod 61 is turned on, and after the electric push rod 61 extends, it pushes the positioning bracket 62 to slide upward. The positioning bracket 62 drives the arc-shaped pressing plate 63 to move, and the arc-shaped pressing plate 63 drives the pressing column 65 to abut tightly against the outer wall of the workpiece and continuously pushes the workpiece, and drives the rotating motor 53 to move upward, so that the limit block 52 slides along the limit sliding frame 51 until the outer wall of the workpiece contacts the bottom of the grinding head 4, and the workpiece is always pressed against one side of the grinding head 4. When the rotating motor 53 drives the workpiece to rotate, the second electric slide rail 66 is turned on, and the second electric slide rail 66 drives the arc-shaped plate 68 to move through the movable plate 67. The arc-shaped plate 68 drives the sponge pad 610 to move away from the bottom of the pressing column 65. At this time, the pressing column 65 is no longer blocked by the sponge pad 610, and the workpiece can drive the pressing column 65 to rotate when rotating, reducing the friction force in contact with the workpiece. When the arc-shaped pressing plate 63 moves, it drives the positioning rod 693 to move through the extension plate 694, and the positioning rod 693 drives the brush roller 691 to abut tightly against the outer wall of the workpiece through the limit bracket 692. When the workpiece rotates past the brush roller 691, the brush roller 691 can clean the outer wall of the workpiece.
