Description

Technical Field

[0001] This utility model belongs to the field of hardware processing technology, specifically relating to an inner wall polishing device for sleeve hardware processing. Background Technology

[0002] As a key component in the hardware processing industry, sleeves are widely used in mechanical transmission, pipeline connection, and building installation. The smoothness of their inner walls directly affects assembly accuracy, fluid transport efficiency, and service life. For example, in applications such as hydraulic pipelines and precision instrument sleeves, burrs, scratches, or excessive roughness on the inner walls can lead to increased medium flow resistance, decreased sealing performance, and even component wear or failure. Therefore, polishing the inner walls of sleeves is one of the core processes to ensure their performance meets standards.

[0003] Currently, the polishing of the inner wall of pipes mostly relies on manual hand tools or simple equipment, which has obvious limitations: on the one hand, the traditional method has poor adaptability to pipes of different lengths, requires frequent changes of fixtures or adjustments of equipment, which is cumbersome and time-consuming, and it is difficult to effectively polish the deep inner wall, making it difficult to achieve efficient batch processing. Utility Model Content

[0004] The purpose of this invention is to provide an inner wall polishing device for sleeve hardware processing, which solves the problems existing in the background art.

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows: An inner wall polishing device for sleeve hardware processing, comprising: Mounting frame, which serves as the mounting base for the entire device; Two rotating rollers are rotatably mounted on the mounting frame, and the two rotating rollers are arranged symmetrically front to back; The housing is mounted on the mounting bracket; An electric motor is disposed inside the housing, and the electric motor is connected to one of the rotating rollers; Two mounting rods are mounted on the mounting bracket; At least two baffles are slidably mounted on the two mounting rods.

[0012] The beneficial effects of this utility model are: By filling the inside of the sleeve with abrasive, the motor drives the rotating roller to rotate the sleeve at a constant speed.

Detailed Implementation

[0016] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-7 As shown, an inner wall polishing device for sleeve hardware processing includes: Mounting frame 1 serves as the mounting base for the entire device. Two rotating rollers 11 are rotatably mounted on the mounting frame 1, and the two rotating rollers 11 are arranged symmetrically front and rear. The housing 12 is mounted on the mounting bracket 1; Motor 13 is installed inside housing 12 and is connected to one of the rotating rollers 11; Two mounting rods 14 are mounted on the mounting bracket 1; At least two baffles 15 are slidably mounted on two mounting rods 14.

[0018] Rotating plate 151 is rotatably disposed at one end of each baffle 15.

[0019] Mounting bracket 1 serves as the fundamental load-bearing structure of the entire device, supporting and securing all components and providing a stable mounting platform for each component. Its rigid structure bears the weight of each component and the forces generated during operation, ensuring the overall stability of the device and guaranteeing the coordinated operation of all components.

[0020] The rotating roller 11 supports the tube to be polished and drives the tube to rotate synchronously. The two rotating rollers are symmetrically distributed front and back, and the tube is placed above the two rotating rollers 11 to form a stable support. When the motor 13 drives one of the rotating rollers 11 to rotate, the friction between the rotating roller 11 and the outer wall of the tube drives the tube to rotate synchronously with the rotating roller 11. At the same time, the tube drives the other rotating roller 11 to rotate passively through friction, realizing the stable rotation of the tube and providing the power basis for polishing the inner wall of the internal abrasive.

[0021] The housing 12 is used to provide a fixed mounting position for the motor 13 and to protect the motor 13 from external objects affecting its operation.

[0022] The motor 13 provides a power source for the device, driving the rotating roller 11 to rotate. It converts electrical energy into mechanical energy, which is connected to one of the rotating rollers 11 through the output shaft, directly driving the rotating roller to rotate. In turn, the friction force drives the pipe and the other rotating roller to move synchronously, making it the core source of power for the device.

[0023] Mounting rod 14 provides a sliding track for baffle 15, allowing baffle 15 to be adjusted axially to accommodate pipes of different lengths. Through sliding engagement with baffle 15, baffle 15 is allowed to move axially along mounting rod 14, thereby adjusting the distance between the two baffles 15 to meet the sealing requirements of pipes of different lengths and improve the device's adaptability to pipe specifications.

[0024] The baffle 15 is used to seal both ends of the pipe to prevent the abrasive material inside the pipe from falling out of the openings at both ends during the rotary polishing process. It also provides a mounting carrier for the rotating plate 151 and the limiting roller 152. The baffle 15 slides along the mounting rod 14 to both ends of the pipe, with its opposite ends aligned with the pipe ends. It forms a closed space through contact with the rotating plate 151 and the pipe, preventing the abrasive material from overflowing. Its sliding characteristics allow it to adapt to pipes of different lengths, ensuring a sealing effect.

[0025] The rotating plate 151 is used to rotate synchronously with the pipe end when in contact with it, avoiding wear or obstruction of rotation of the pipe end due to the fixed baffle 15. The rotating plate 151 is installed on the baffle 15 via a rotating shaft or other structure. When the pipe rotates, the rotating plate 151 rotates synchronously under the friction force of the pipe end, reducing relative friction with the pipe, ensuring smooth rotation of the pipe, and maintaining the sealing of the abrasive material.

[0026] It should be noted that there is a certain gap between the lower part of the baffle 15 and the rotating roller 11, and the center of the rotating plate 151 corresponds to the center of the tube after it is placed on the rotating roller 11.

[0027] In one alternative embodiment, the end of the rotating plate 151 can be designed at an angle so that its end can penetrate into the opening of the tube, thereby improving clamping stability.

[0028] Through the combination of the above structures, the abrasive material is first inserted into the tube, and the tube is placed between two rotating rollers 11. The sliding baffles 15 along the mounting rod 14 are moved to both ends of the tube and fixed, forming a seal on the tube. Then, the motor 13 is started, and the rotating rollers 11 drive the tube to rotate, so that the abrasive material inside the tube can fully rub against the inner wall during rotation, completing the polishing operation. The entire process achieves stable support for the tube, power transmission, adaptation and adjustment, and leakage prevention of the abrasive material, ultimately achieving the function of polishing the inner wall of the casing.

[0029] Furthermore, the mounting rod 14 is provided with multiple fixing components 2, the fixing components including: The retaining ring 21 is slidably mounted on the mounting rod 14; The fixing piece 22 is disposed at the end of the fixing ring 21 facing the baffle 15; The fixing strip 23 is set on the fixing piece 22, and the outer side of the outer wall of the fixing strip 23 is provided with a protrusion. The inner wall of the connecting groove between the baffle 15 and the mounting rod 14 is provided with a protrusion on the side away from the fixing ring 21 that matches the fixing strip 23.

[0030] The retaining ring 21 provides a base for sliding and positioning the fixing assembly 2 on the mounting rod 14, and is the load-bearing component of the entire fixing assembly. The retaining ring 21 is slidably sleeved on the mounting rod 14 and can move freely along the axial direction of the mounting rod 14, making it easy to adjust to a suitable position on the outside of the baffle 15, and providing support for the subsequent fixing of the baffle 15.

[0031] The fixing plate 22 serves as the mounting base for the fixing strip 23, transmitting the axial thrust of the fixing ring 21 and driving the fixing strip 23 into the connecting groove between the mating baffle 15 and the mounting rod 14.

[0032] The fixing strip 23 is the core component for connecting the baffle 15 and the mounting rod 14. It relies on its own elastic deformation and the protrusion on the outer side of its end to cooperate with the protrusion in the connecting groove of the baffle 15 and the mounting rod 14. The protrusion of the baffle 15 contacts the protrusion of the fixing strip 23, thereby squeezing the fixing strip 23 to undergo elastic deformation. The deformed fixing strip 23 squeezes the mounting rod 14, thereby generating friction and fixing the baffle 15 axially on the mounting rod 14, thus playing a role in axially limiting the pipe.

[0033] Furthermore, each baffle 15 is rotatably mounted with multiple limit rollers 152 at one end.

[0034] The limiting rollers 152 are used to assist in limiting the radial displacement of the pipe, preventing the pipe from deviating during rotation, ensuring that its axis is parallel to the axis of the rotating roller 11, and improving stability. Multiple limiting rollers 152 are distributed circumferentially along the pipe at opposite ends of the baffle 15, contacting the outer wall of the pipe. When the pipe rotates, the limiting rollers 152 rotate synchronously with the pipe, reducing resistance through rolling friction, and simultaneously limiting the radial sway of the pipe by their own position, ensuring stable rotation of the pipe.

[0035] Furthermore, a feeding mechanism 3 is provided on the lower side of the middle part of the mounting frame 1. The feeding mechanism includes: Mounting slot 31 is provided at the lower middle of the housing 12; The support column 32 is rotatably mounted in the mounting groove 31; The support roller 33 is rotatably mounted at the outer end of the support column 32.

[0036] The mounting slot 31 is a groove structure opened in the middle of the lower end of the housing 12, which is used to provide space for the support column 32 to be installed and rotated.

[0037] One end of the support column 32 is rotatably mounted in the mounting groove 31, and the other end is connected to the support roller 33. By rotating, the length of the extension is adjusted to support one side of the mounting frame 1, causing the device to tilt and create a height difference. When feeding is required, the support column 32 is rotated around the pivot in the mounting groove 31, and the support column 32 extends outward to support one side of the mounting frame 1, using the lever principle to lift the mounting frame 1.

[0038] It should be noted that the maximum rotation angle of the support column 32 is greater than 90 degrees. When the rotation exceeds 90 degrees, it maintains its tilted state by abutting against the mounting bracket 1.

[0039] The support roller 33 is a cylindrical roller body, rotatably mounted on the outer end of the support column 32, and can rotate freely around its own axis. It is used to reduce friction between the support column 32 and the ground, facilitating the adjustment of the tilt angle of the mounting frame 1. When the support column 32 supports the mounting frame 1, the support roller 33 is in contact with the ground; when adjusting the tilt angle, the support roller 33 rotates with the movement of the support column 32, converting sliding friction into rolling friction, reducing adjustment resistance, and making the adjustment of the tilt angle of the mounting frame 1 more effortless and smoother.

[0040] Furthermore, the mounting groove 31 is provided with a protrusion that matches the support column 32.

[0041] The protrusion in the mounting groove 31 is integrally formed on the inner wall of the mounting groove 31 (near the corresponding position of the lower end of the support column 32 when parallel), and is made of a material with a certain elastic deformation capability (such as elastic plastic or metal sheet). When the support column 32 is parallel to the mounting groove 31 (i.e., the retracted state of the support column 32), the protrusion abuts against the lower end of the support column 32 when parallel, thereby restricting the free rotation of the support column 32 and preventing it from unfolding when the device is not in operation.

[0042] Furthermore, storage plates 16 are provided on both the front and rear sides of the mounting bracket 1.

[0043] The storage plate 16 is symmetrically arranged on the front and rear sides of the mounting frame 1, forming a semi-enclosed space together with the support plate in the middle of the mounting frame 1 to prevent abrasive leakage and assist in collecting abrasive. After grinding, the abrasive can be poured directly onto the plate. The storage plate 16 further prevents abrasive overflow and facilitates subsequent collection.

[0044] Furthermore, the mounting bracket 1 is inclined between the two storage plates 16, and a discharge hole 17 is provided at the lowest point of the inclined plate of the mounting bracket 1, and a plug 18 is threaded onto the discharge hole 17.

[0045] The inclined design of the middle plate of mounting bracket 1 is designed to allow the abrasive to naturally gather towards the lowest point through gravity.

[0046] The discharge hole 17 is a circular through hole opened at the lowest point of the inclined plate of the mounting bracket 1. The inner wall is threaded to serve as a channel for abrasive discharge, realizing the centralized recycling of abrasive after grinding. The discharge hole 17 is set at the lowest point so that the accumulated abrasive can be discharged in a concentrated manner to avoid abrasive residue.

[0047] The plug 18 is a cap-like structure with external threads that matches the internal threads of the discharge hole 17. It is used to seal the discharge hole 17 to prevent abrasive leakage during grinding. When the abrasive needs to be removed, the plug 18 is unscrewed, and the abrasive that has accumulated at the lowest point can be discharged through the discharge hole 17, realizing convenient recycling of the abrasive.

[0048] How to use this embodiment: In the preparation stage, the sleeve is placed horizontally between two rotating rollers 11. The grinding abrasive (grinding material) is filled into the sleeve to be polished. During feeding, the tilt angle of the mounting frame 1 is adjusted by rotating the support column 32, and the support roller 33 reduces the adjustment resistance. After the tube is placed, the lower end of the tube is blocked by one of the baffles 15. When the abrasive is placed, it is not easy to leak out due to the tilt angle and the blockage of the baffle 15. The other baffle 15 is slid along the mounting rod 14, pushing the baffle 15 towards the end of the tube until the rotating plate 151 abuts against the end of the tube. The fixing ring 21 is pushed along the mounting rod towards the baffle 15. When the fixing plate 22 enters the connecting groove of the baffle 15, the outer protrusion of the fixing strip 23 contacts the protrusion in the connecting groove of the baffle 15, squeezing the fixing strip 23 into elastic bending. The outer side of the deformed fixing strip 23 is squeezed by the baffle 15, and the inner side squeezes the mounting rod 14, generating friction to hinder sliding. Finally, the baffle is axially fixed on the mounting rod to ensure the sealing effect. Once preparation is complete, start motor 13. The output shaft of motor 13 drives one of the rotating rollers 11 to rotate. The friction between the rotating roller 11 and the outer wall of the pipe causes the pipe to rotate synchronously. The pipe then drives the other rotating roller 11 to rotate passively through friction, gradually completing the inner wall polishing.

[0049] Through the process of "filling → supporting → sealing → driving → polishing", the frictional transmission of the rotating roller, the self-adaptive sealing of the baffle, the locking of the fixed component, and the synchronous processing of the outer wall mechanism are used to achieve efficient and stable polishing of the inner wall of the sleeve, adapt to different lengths of pipes, and ensure leakage prevention and processing accuracy of the abrasive.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
