Description

Technical Field

[0001] The utility model relates to the field of casting gate grinding machines, in particular to a carbon steel casting gate grinding machine. Background Art

[0002] Carbon steel castings play an important role in the foundry industry. However, after the casting is formed, the gate often has roughness, unevenness, and excess material, requiring subsequent polishing to meet product quality requirements.

[0003] After searching, Chinese Patent Publication No. CN219026943U discloses a carbon steel casting gate grinding machine, which includes a frame, a clamping mechanism, and a forward movement mechanism. The grinding mechanism is mounted on the top side wall of the frame, and a reciprocating mechanism is provided between the forward movement mechanism and the clamping mechanism. The reciprocating mechanism includes two fixed plates, a reciprocating screw is rotatably provided between the two fixed plates, a nut seat is provided on the outer wall transmission sleeve of the reciprocating screw, and the nut seat is fixed to the clamping mechanism. A drive motor connected to the reciprocating screw is fixed on the outer wall of one of the fixed plates. The utility model drives the clamping mechanism to move horizontally back and forth through the reciprocating mechanism, which is arranged between the forward movement mechanism and the clamping mechanism. The reciprocating mechanism, which is composed of the fixed plate, the reciprocating screw, the nut seat, and the drive motor, is arranged between the forward movement mechanism and the clamping mechanism. This allows the clamped carbon steel casting to fully contact all parts of the grinding roller surface, improves the wear uniformity of the grinding roller, thereby extending the service life of the grinding roller and improving the grinding quality of the carbon steel casting gate.

[0004] Although the device has been improved to a certain extent, it still has the following shortcomings. First, the carbon steel casting gates are mostly cylindrical, and the device is clamped only by two plates with flat contact surfaces, namely the side baffle and the movable clamping plate. When clamping, there are fewer contact points with the cylindrical carbon steel casting gate, and the stability during clamping is poor and easy to loosen. In addition, after the carbon steel casting gate is clamped and fixed, the device cannot rotate, which easily causes the edges of the carbon steel casting gate at different angles to be unable to contact the grinding roller evenly, which will affect the grinding quality.

[0005] For this reason, a carbon steel casting gate grinding machine is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Since it is a prior art, it will not be described in detail in this case. An electric telescopic rod 3 is provided on the upper surface of the machine platform 1, and the electric telescopic rod 3 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The rear end of the electric telescopic rod 3 is fixedly connected with a movable plate 4, and the electric telescopic rod 3 can drive the movable plate 4 to move in the forward and backward directions. The upper surface of the movable plate 4 is fixedly connected with a support plate 5, and the upper surface of the support plate 5 is provided with a fixing mechanism, which can clamp and fix the columnar carbon steel casting gate, and a limiting component is provided inside the support plate 5.

[0033] Reference Figure 2 - Figure 4 The fixing mechanism includes an adjusting component and a clamping component. The adjusting component includes a disc 61. A motor 65 is provided on the front surface of the disc 61. The disc 61 provides support for the motor 65. The motor 65 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The motor 65 is a stepping motor with a very slow speed. The output shaft of the motor 65 is fixedly connected to the positioning disc 62. After the motor 65 is started, it can drive the positioning disc 62 to rotate. A slide groove 601 is provided on the rear surface of the disc 61, and an arc groove 602 is provided on the rear surface of the positioning disc 62. The arc groove 602 corresponds to the slide groove 601. The inner wall of the slide groove 601 is slidably connected to a slide rod 63. The rear surface of the slide rod 63 is fixedly connected to a connecting block 64. The clamping assembly includes a round rod 73. The left surface of the connecting block 64 is fixedly connected to one end of a compression spring 72, and the other end of the compression spring 72 is fixedly connected to a clamping plate 71.

[0034] Reference Figure 1 - Figure 2The limiting component includes a slot 801, which is opened into a tooth shape. The inner wall of the support plate 5 is elastically connected with a block 81 through a limit spring 82. The left end of the block 81 is set to a tooth shape. The front surface of the block 81 is fixedly connected to a moving block 83, and the front surface of the moving block 83 is fixed with a pull ring.

[0035] Reference Figure 2 - Figure 4 The movable plate 4 is slidably connected to the upper surface of the machine 1 and slides in the front and rear directions. The disc 61 is rotatably connected to the upper surface of the support plate 5, and the positioning plate 62 is rotatably connected to the inner wall of the disc 61. The output shaft of the motor 65 passes through the front surface of the disc 61. The disc 61 and the positioning plate 62 are concentric, and the slide rod 63 is slidably connected to the inner wall of the arc groove 602. When the positioning plate 62 rotates, it will drive the arc groove 602 to move, and then squeeze the slide rod 63 to make it move along the trajectory of the slide groove 601. The round rod 73 passes through and is slidably connected to the left surface of the connecting block 64. The left surface of the round rod 73 is fixedly connected to the right surface of the splint 71. When the splint 71 moves to the right, it squeezes the compression spring 72 to generate a reaction force, and the splint 71 can move, which can effectively avoid the problem of the splint 71 in different directions not being clamped properly due to the slight bulge on the gate surface of the columnar carbon steel casting. The splint 71 is set to an arc shape.

[0036] Reference Figure 1 - Figure 2 The card slot 801 is opened on the outer wall of the disc 61. There are multiple groups of card slots 801, which are arranged in a circular array with the center of the disc 61 as the origin. The card block 81 is slidably connected to the inner wall of the support plate 5. One end of the limit spring 82 is fixedly connected to the right surface of the card block 81, and the other end of the limit spring 82 is fixedly connected to the inner wall of the right side of the support plate 5. When the card block 81 moves to the right, it squeezes the limit spring 82 to generate a reaction force. The card block 81 is inserted into the inner wall of the card slot 801, which can limit the disc 61. The moving block 83 passes through and is slidably connected to the front surface of the support plate 5.

[0037] Working principle: When using this device, first place the columnar carbon steel casting gate that needs to be fixed between multiple groups of splints 71, and then start the motor 65 to drive the positioning plate 62 to rotate. The rotating positioning plate 62 will drive the arc groove 602 to move, and the moving arc groove 602 will squeeze the slide bar 63. After being squeezed, the slide bar 63 will move toward the middle of the disc 61 along the trajectory of the slide groove 601. The slide bar 63 will drive the connecting block 64, the splint 71, the compression spring 72 and the round rod 73 to move synchronously. When the splint 71 contacts the surface of the columnar carbon steel casting gate, let go. At this time, the connecting block 64 will continue to move toward the middle of the disc 61. Since the splint 71 and the surface of the columnar carbon steel casting gate are in contact and cannot move, the compression spring 72 will be squeezed, and the splint 71 will tightly clamp the columnar carbon steel casting gate to maintain stability during clamping.

[0038] After stable clamping, turn off the motor 65 to keep the device stable, then start the electric telescopic rod 3 to push the movable plate 4, the support plate 5, the disc 61 and the columnar carbon steel casting gate backward to the appropriate position, then close the electric telescopic rod 3, and start the grinding mechanism 2 to grind the columnar carbon steel casting gate. During the grinding process, if the angle of the columnar carbon steel casting gate needs to be adjusted, the grinding mechanism 2 can be turned off, and then the moving block 83 is pulled to the right to drive the card block 81 to move to the right. The card block 81 moving to the right will squeeze the limit spring 82 to generate a reaction force and will disengage from the card slot 801 to release the limit on the disc 61, and then rotate the disc 61 to drive The motor 65, the positioning plate 62 and the columnar carbon steel casting gate rotate to achieve angle adjustment. After the adjustment is completed, the moving block 83 is released, and the reaction force of the limit spring 82 will push the clamping block 81 to move to the left and the clamping slot 801 to limit the disc 61 and keep it stable. Then start the grinding mechanism 2 to continue grinding the columnar carbon steel casting gate. After the grinding is completed, first start the electric telescopic rod 3 to drive the moving plate 4, the support plate 5 and the columnar carbon steel casting gate to move forward, and then start the motor 65 to drive the positioning plate 62 to rotate in the opposite direction, and then drive the clamping plate 71 to open and release the clamping of the columnar carbon steel casting gate, and then remove the columnar carbon steel casting gate.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
