[0004] To achieve the above purpose, the present application provides the following technical scheme: a deburring and polishing device for stainless steel casting machining, comprising a reserved base, a driving motor shaft is installed on the inner side of the reserved base, and the lower end of the driving motor shaft is in mutual butt joint with a preset motor, and the upper end of the driving motor shaft is fixedly connected with a first butt joint piece; a nested butt joint piece is nested in the upper end of the reserved base, and the first butt joint piece is arranged on the inner side of the nested butt joint piece, a horizontal butt joint piece is nested and installed on the inner side of the reserved base, and a driving polishing roller is installed on the upper end of the horizontal butt joint piece through an embedded motor, and a guide locking structure is arranged on the inner side of the reserved base, and the workpiece to be machined in contact with the guide locking structure is self-locked.

[0005] Further, the guide locking structure is provided with a limiting butt joint piece, the limiting butt joint piece is nested and installed on the outer side of the nested butt joint piece, and the inner side of the limiting butt joint piece is in mutual butt joint with the nested butt joint piece through a spring, and the lower end of the limiting butt joint piece corresponds in position to the outer side of the first butt joint piece.

[0006] Further, the lower end of the driving motor shaft is fixedly connected with a second butt joint piece, the inner side of the reserved base is nested with an embedded nesting piece, the outer side of the embedded nesting piece corresponds in position to the outer side of the second butt joint piece, the outer side of the embedded nesting piece is fixedly connected with a reserved steel rope assembly, the reserved steel rope assembly penetrates along the inner side of the reserved base, the end of the reserved steel rope assembly is in mutual butt joint with the lower end of the horizontal butt joint piece, and the outer side of the horizontal butt joint piece is fixedly connected with a first reserved spring, and the first reserved spring is in mutual butt joint with the inner side of the reserved base.

[0007] Furthermore, during the rotation of the first contacting docking member, its outer side pushes and presses against the contacting limiting contacting member outward, and the limiting contacting member moves laterally along the outer side of the nested docking member, while the nested docking member rotates around the upper circumference of the reserved base.

[0008] Furthermore, during the rotation of the second abutting docking member, it applies lateral pressure to the contacting inner nesting member, and the inner nesting member moves along the inner side of the reserved base. The inner nesting member drives the lateral docking member to move laterally along the inner side of the reserved base through the reserved steel rope assembly. The lateral docking member forms an elastic support structure along the inner side of the reserved base through the first reserved spring.

[0009] Furthermore, a guiding and cleaning structure is provided between the transverse docking component and the reserved base, which adaptively cleans impurities formed during the operation of the reserved base. The guiding and cleaning structure is provided with a built-in piston component, which docks with the inner side of the reserved base. A reserved air storage chamber is opened on the inner side of the reserved base, and the built-in piston component is nested and docked with the inner side of the reserved air storage chamber. A second reserved spring is fixedly connected to the outer side of the built-in piston component, and the second reserved spring docks with the inner side of the reserved air storage chamber.

[0010] Furthermore, a reserved through hole is provided on the outer side of the reserved air storage chamber, and a filter screen structure is provided on the inner side of the reserved through hole. A supply pipe is connected through the outer end of the reserved air storage chamber.

[0011] Furthermore, during the inward movement of the transverse docking member, the contacting built-in piston member is simultaneously pressed inward, and when the built-in piston member is displaced, the second reserved spring is stretched and moves laterally along the reserved air storage cavity.

[0012] Furthermore, when the built-in piston moves to the right side of the reserved through hole, the reserved air storage chamber is in a closed state, and the built-in piston supplies air pressure to the outside through the supply pipe. When the built-in piston returns to the left side of the reserved through hole, the reserved air storage chamber is in a connected state.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This deburring and grinding device based on stainless steel casting processing is equipped with a guide locking structure. The guide locking structure self-locks the contacting workpiece. The drive motor shaft drives the first and second contacting parts to rotate synchronously. During the rotation of the first contacting part, it pushes and presses the outer contacting limiting contacting part outward, allowing the laterally moving limiting contacting part to self-lock the inner side of the contacting cylindrical workpiece. After the work is completed, it automatically releases the lock. In conjunction with the circumferentially rotating nested contacting part, it effectively drives the self-locked workpiece to perform multi-directional surface treatment with the contacting drive grinding roller. Even when processing tubular stainless steel castings with different inner diameters, it can effectively perform inner diameter locking and positioning. While ensuring the contact surface between the processed workpiece and the deburring structure, it performs all-round grinding operations, ensuring the practicality of the device. Furthermore, during the rotation of the second contacting part, its outer side will apply lateral pressure to the inner nesting part, causing the inner nesting part to drive the lateral contacting part to move laterally along the inner side of the reserved base through the reserved steel rope assembly. The lateral contacting part will drive the upper drive grinding roller connected to the external line through the built-in motor to move synchronously, thereby allowing the drive grinding roller of the brush structure to reciprocate and make uniform contact with the workpiece on the outside of the circumferentially rotating limit contacting part, thus ensuring the efficient processing quality of the workpiece grinding and forming state, and making the overall processing quality more excellent. Furthermore, a guided cleaning structure is provided. This structure adaptively cleans impurities formed during the pre-reserved base operation. As the transverse connecting part moves laterally along the inner side of the pre-reserved base via the drive structure, it applies transverse pressure to the contacting built-in piston, causing the built-in piston to reciprocate along the interior of the pre-reserved air storage chamber. When the built-in piston moves to the right side of the pre-reserved through hole, the interior of the pre-reserved air storage chamber is sealed. This allows the continuously moving built-in piston to supply air pressure to the outside through the supply pipe, thereby quickly removing impurities remaining on the surface of the pre-reserved base and preventing them from accumulating on the outside of the workpiece, ensuring the overall processing quality and forming effect of the workpiece.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1-10 The present invention provides the following technical solution: a deburring and grinding device based on stainless steel casting processing. To solve the technical problem of being unable to effectively lock and position the inner diameter of tubular stainless steel castings with different inner diameters during processing, the device discloses a configuration including: a drive motor shaft 2 installed on the inner side of a reserved base 1, with the lower end of the drive motor shaft 2 connected to a preset motor; a first abutting docking member 3 fixedly connected to the outer side of the upper end of the drive motor shaft 2; a nested docking member 4 nested within the upper end of the reserved base 1, with the first abutting docking member 3 located inside the nested docking member 4; a transverse docking member 9 nested within the inner side of the reserved base 1, with a drive grinding roller 10 installed at the upper end of the transverse docking member 9 via a built-in motor; and a guide locking structure provided within the reserved base 1, which self-locks the contacting workpiece.

[0018] The guide locking structure is equipped with a limiting contact connector 5, which is nested on the outside of the nested docking member 4. The inner side of the limiting contact connector 5 is connected to the nested docking member 4 via a spring. The lower end of the limiting contact connector 5 corresponds to the outer side of the first docking member 3. The lower outer side of the drive motor shaft 2 is fixedly connected to a second docking member 6. An inner nested member 7 is nested on the inner side of the reserved base 1, and the outer side of the inner nested member 7 corresponds to the outer side of the second docking member 6. A reserved steel rope assembly 8 is fixedly connected to the outer side of the inner nested member 7, and the reserved steel rope assembly 8 passes through the inner side of the reserved base 1. The end of the reserved steel rope assembly 8 is aligned with the lower end of the transverse docking member 9. Next, a first reserved spring 11 is fixedly connected to the outer side of the transverse docking member 9, and the first reserved spring 11 is connected to the inner side of the reserved base 1. During the rotation of the first abutting docking member 3, its outer side pushes and presses the contact limiting abutting connecting member 5 outward, and the limiting abutting connecting member 5 moves laterally along the outer side of the nested docking member 4, and the nested docking member 4 rotates circumferentially along the upper end of the reserved base 1. During the rotation of the second abutting docking member 6, it applies lateral pressure to the contacting inner nested member 7, and the inner nested member 7 moves along the inner side of the reserved base 1. The inner nested member 7 drives the transverse docking member 9 to move laterally along the inner side of the reserved base 1 through the reserved steel rope assembly 8. The transverse docking member 9 moves laterally along the reserved base 1 through the first reserved spring 11. An elastic support structure is formed on the inner side. During the overall operation, the drive motor shaft 2 will drive the first contacting docking member 3 and the second contacting docking member 6 to rotate synchronously. During the rotation of the first contacting docking member 3, it will push and press the outer contacting limiting docking connecting member 5 outward, so that the laterally movable limiting docking connecting member 5 can perform self-locking treatment on the inner side of the contacting cylindrical workpiece. At the same time, after the work is completed, it will automatically release the lock. In conjunction with the circumferentially rotating nested docking member 4, it can effectively drive the self-locked workpiece and the contacting drive grinding roller 10 to perform multi-directional surface treatment. Even when processing tubular stainless steel castings with different inner diameters, it can effectively perform inner diameter locking and positioning treatment, ensuring the contact surface between the processed workpiece and the burr grinding structure, while also ensuring its... A comprehensive grinding operation is performed. During the rotation of the second contacting part 6, its outer side applies lateral pressure to the inner nesting part 7, causing the inner nesting part 7 to drive the lateral contacting part 9 to move laterally along the inner side of the reserved base 1 via the reserved steel rope assembly 8. The lateral contacting part 9 then drives the driving grinding roller 10, which is connected to the external circuit via an internal motor, to move synchronously. This allows the brush-structured driving grinding roller 10 to reciprocate and make uniform contact with the workpiece on the outer side of the circumferentially rotating limiting contacting part 5, thus ensuring efficient processing quality of the workpiece's grinding and shaping state. The flexible driving grinding roller 10 with its brush structure can meet the grinding needs of workpieces of different diameters. Simultaneously, as the inner nesting part 7 is released from the stress state...The transverse connecting piece 9 will return to its original position using the restoring force of the first reserved spring 11, thereby driving the built-in nested piece 7 to return to its original position synchronously via the reserved steel rope assembly 8, meeting the subsequent continuous reciprocating grinding requirements.

[0019] Example 2: Based on Example 1, to address the problem that the limited contact area between the workpiece and the burr grinding structure prevents comprehensive grinding operations, a guided removal structure is also disclosed, the specific structure of which is as follows: A guide cleaning structure is provided between the transverse connecting part 9 and the reserved base 1. The guide cleaning structure can adaptively clean the impurities formed during the operation of the reserved base 1. The guide-clearing structure is equipped with a built-in piston 12, which is mated to the inner side of the reserved base 1. A reserved air storage chamber 13 is provided on the inner side of the reserved base 1. The built-in piston 12 is nested and mated to the inner side of the reserved air storage chamber 13. A second reserved spring 14 is fixedly connected to the outer side of the built-in piston 12, and the second reserved spring 14 is mated to the inner side of the reserved air storage chamber 13. A reserved through hole 15 is provided on the outer side of the reserved air storage chamber 13, and a filter screen structure is provided on the inner side of the reserved through hole 15. A supply pipe 16 is connected through the outer end of the reserved air storage chamber 13. During the inward movement of the transverse docking member 9, the contacting built-in piston 12 is simultaneously pressed inward. When the built-in piston 12 moves, it stretches the second reserved spring 14 and moves laterally along the reserved air storage chamber 13. When the built-in piston 12 moves to the right side of the reserved through hole 15, the interior of the reserved air storage chamber 13 is in a closed state. 2. Air pressure is supplied outward through the supply pipe 16. When the built-in piston 12 is reset to the left side of the reserved through hole 15, the reserved air storage chamber 13 is in a connected state. During the process of the transverse docking part 9 moving laterally along the inner side of the reserved base 1 through the drive structure, it will apply transverse pressure to the contacted built-in piston 12, causing the built-in piston 12 to reciprocate along the interior of the reserved air storage chamber 13. When the built-in piston 12 moves to the right side of the reserved through hole 15, the interior of the reserved air storage chamber 13 is in a closed state. Thus, the continuously moving built-in piston 12 is supplied outward through the supply pipe 16. With the cooperation of the one-way valve structure set inside the supply pipe 16, the impurities remaining on the surface of the reserved base 1 are quickly removed, preventing them from accumulating on the outside of the workpiece. With the continuous contact grinding of the equipment, the surface of the workpiece is cleaned multiple times.
