Description

Technical Field

[0001] This utility model relates to the field of accessory polishing technology, specifically to an adjustable ceramic fiber brush for outer circles. Background Technology

[0002] The adjustable ceramic fiber brush for external diameters is a tool used for fine grinding, cleaning, or processing of externally circular workpieces. Its design allows for adjustment of bristle hardness and length under various conditions to adapt to different materials and processing requirements. The core of its design is to overcome the limitations of traditional brushes in terms of adjustment accuracy, bristle life, installation compatibility, and transmission stability, in order to meet the needs of precision manufacturing and flexible production. Combined with the adaptation requirements of automated equipment, it achieves high efficiency, stability, and low cost in external diameter surface treatment by optimizing the key positions of the adjustment mechanism and bristle assembly.

[0003] A ceramic fiber slag removal brush disclosed in publication number CN209669568U, although rotatably positioned below the wet fiber blank and maintaining close contact with it at all times, is composed of a tubular slag removal brush body, an elastic pad, and nylon abrasive cloth. The top surface of the nylon abrasive cloth has numerous protruding nylon abrasive particles, and the bottom surface of the nylon abrasive cloth surrounds the outer wall of the slag removal brush body and covers its surface. The elastic pad is positioned between the slag removal brush body and the nylon abrasive cloth, and the two are fixed together by an adhesive layer. This invention utilizes the friction between the surface nylon abrasive cloth and the wet fiber blank to peel away slag balls deposited beneath the fibers, effectively removing residual slag balls and increasing the fiber ratio. The elastic pad in the middle ensures that the surface nylon abrasive cloth remains in close contact with the wet fiber blank, guaranteeing operational stability and processing quality. This slag removal brush is easy to manufacture, simple to operate, low in cost, and readily achievable.

[0004] However, this ceramic fiber slag removal brush has the following disadvantages: due to the simple structure of the fixed diameter brush, there are many different diameters, steps and conical surfaces on the outer circular workpiece, and the size often needs to be changed in batches, which leads to frequent replacement, resulting in long downtime and high cost. Utility Model Content

[0005] The technical problem to be solved by this utility model is as follows: to provide a highly practical, simple-to-operate, and structurally simple adjustable ceramic fiber brush for outer circles, which solves the problem mentioned in the background art that due to the simple structure of fixed diameter brushes, there are multiple diameter specifications, steps and conical surfaces and other irregular structures of outer circle workpieces, and the need to frequently change sizes in batches, resulting in frequent replacements, long downtime and high costs.

[0006] The objective of this utility model can be achieved through the following technical solutions: An adjustable ceramic fiber brush for outer diameter includes a housing body, characterized in that: a sleeve is fixedly connected to one end of the housing body, a telescopic assembly is rotatably connected to the inner wall of the sleeve, a mounting plate is fixedly connected to one end of the housing body, and multiple sets of fixing pin assemblies are fixedly connected to the middle of the mounting plate; the telescopic assembly includes a threaded rod rotatably connected to the inner wall of the sleeve, and a threaded tube is slidably connected to the other end of the threaded rod; the fixing pin assembly includes a sleeve rod fixedly connected to the middle of the mounting plate, a push rod is slidably connected to the inner wall of the sleeve rod, and two sets of limiting rods are rotatably connected to the surface of the push rod.

[0007] As a further embodiment of this utility model: a rotating handle is fixedly connected to one end of the threaded rod, two sets of strip grooves are opened on the surface of the threaded rod, two sets of limiting strips are provided on the inner wall of the threaded tube, and a fixing block is fixedly connected to one end of the threaded tube. The setting of the strip grooves facilitates the insertion and connection of the limiting strips. The rotation of the threaded rod drives the threaded tube to rotate and moves axially together with the stepped tube.

[0008] As a further embodiment of this utility model: a semi-circular groove is provided in the middle of the fixing block, and a limiting ring is fixedly connected in the middle of the semi-circular groove. The limiting ring restricts the axial movement of the threaded tube and can rotate with the rotation of the threaded rod.

[0009] As a further embodiment of this utility model: the surface of the sleeve rod is provided with two sets of limiting grooves, and the surface of the sleeve rod is threaded with a nut. The setting of the nut serves to rotate the nut, thereby strengthening the tightness of the sleeve rod and increasing the thrust of the limiting rod, so that the mounting plate is fixedly connected to the drive structure.

[0010] As a further embodiment of this utility model: a handle is fixedly connected to one end of the sleeve rod, a pressing head is fixedly connected to one end of the push rod, and a spring is fixedly connected to the other end of the push rod. The spring allows the push rod to slide along the inner wall of the sleeve rod, thereby squeezing the spring and pulling the limiting rod through the mounting hole of the drive structure and the mounting hole on the surface of the mounting plate. When the push rod is released, the spring rebounds and resets, causing the limiting rod to be pushed out, while simultaneously squeezing the outer wall of the mounting hole on the other side of the drive structure.

[0011] As a further embodiment of this utility model: a driving structure is fixedly connected to the other side of the mounting plate, and a stepped tube is slidably connected to the other end of the housing body. The stepped tube enables the nut joint at one end of the stepped tube to rotate and move through the rotation of the threaded rod. At the same time, the threaded surface at one end of the inner wall of the mounting tube is threadedly connected to the threaded tube, thereby driving the mounting tube to move.

[0012] As a further embodiment of this utility model: the other end of the stepped tube is slidably connected to an installation tube, one end of the installation tube is fixedly connected to a first set of brushes, and one end of the stepped tube is fixedly connected to a second set of brushes. The installation tube facilitates the effective adjustment of the length of the first set of brushes.

[0013] The beneficial effects of this utility model are: This adjustable ceramic fiber brush for external cylindrical surfaces, with its telescopic assembly, allows for efficient processing of irregularly shaped external cylindrical workpieces with various diameters, steps, and conical surfaces. Manually rotating the handle rotates the threaded rod, which in turn rotates the nut connector at one end of the stepped tube. Simultaneously, the threaded surface at one end of the mounting tube connects to the threaded tube, driving the mounting tube to move. Through the stable engagement of the limiting ring and the semi-circular groove, the threaded tube and threaded rod rotate together and move axially along with the stepped tube. This effectively improves processing efficiency for irregularly shaped external cylindrical workpieces with various diameters, steps, and conical surfaces, reducing downtime and maintenance costs, minimizing manual intervention, enhancing long-term stability, and improving grinding accuracy.

[0014] This externally adjustable ceramic fiber brush, equipped with a fixing pin assembly, allows for easy installation and replacement. The assembly securely connects the brush to the drive structure. First, the sleeve is inserted into the mounting hole in the center of the mounting plate and the inner wall of the mounting hole in the drive structure. Pressing the push rod slides along the inner wall of the sleeve, compressing the spring and pulling the limit rod through the mounting hole in the drive structure and the mounting plate. Releasing the push rod causes the spring to return to its original position, pushing the limit rod out and simultaneously compressing the outer wall of the mounting hole on the other side of the drive structure. Rotating the nut further tightens the sleeve and increases the thrust of the limit rod, securing the mounting plate to the drive structure. This effectively improves the efficiency of ceramic fiber brush installation and replacement, reduces labor time and maintenance costs, enhances the stability and convenience of the brush, increases grinding precision, and extends the equipment's lifespan.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-5 As shown, a special adjustable ceramic fiber brush for outer circles includes a housing body 1. The housing body 1 is characterized by: a sleeve 2 fixedly connected to one end; a telescopic assembly 3 rotatably connected to the inner wall of the sleeve 2; a mounting plate 4 fixedly connected to one end of the housing body 1; and multiple sets of fixing pin assemblies 5 fixedly connected to the middle of the mounting plate 4. The telescopic assembly 3 includes a threaded rod 301 rotatably connected to the inner wall of the sleeve 2; a threaded tube 302 slidably connected to the other end of the threaded rod 301. The fixing pin assembly 5 includes a sleeve rod 501 fixedly connected to the middle of the mounting plate 4; a push rod 502 slidably connected to the inner wall of the sleeve rod 501; and two sets of limiting rods 503 rotatably connected to the surface of the push rod 502. like Figure 3 As shown, a rotating handle 6 is fixedly connected to one end of the threaded rod 301. Two sets of strip grooves 7 are opened on the surface of the threaded rod 301. Two sets of limiting strips 8 are provided on the inner wall of the threaded tube 302. A fixing block 9 is fixedly connected to one end of the threaded tube 302. The setting of the strip grooves 7 facilitates the insertion and connection of the limiting strips 8. The rotation of the threaded rod 301 drives the threaded tube 302 to rotate and move axially together with the stepped tube 18. like Figure 2 As shown, a semi-circular groove 10 is provided in the middle of the fixing block 9, and a limiting ring 11 is fixedly connected in the middle of the semi-circular groove 10. The limiting ring 11 restricts the axial movement of the threaded tube 302 and can rotate with the rotation of the threaded rod 301. like Figure 4As shown, the surface of the sleeve rod 501 is provided with two sets of limiting grooves 12, and the surface of the sleeve rod 501 is threaded with a nut 13. By setting the nut 13, the nut 13 can be rotated to strengthen the fastening of the sleeve rod 501, and at the same time increase the thrust of the limiting rod 503, so that the mounting plate 4 and the drive structure 17 are fixedly connected. like Figure 4 As shown, a handle 14 is fixedly connected to one end of the sleeve rod 501, a pressing head 15 is fixedly connected to one end of the push rod 502, and a spring 16 is fixedly connected to the other end of the push rod 502. The spring 16 is used to press the push rod 502 to slide along the inner wall of the sleeve rod 501, thereby squeezing the spring 16, pulling the limit rod 503 through the inner wall of the mounting hole of the drive structure 17 and the mounting hole on the surface of the mounting plate 4. When the push rod 502 is released, the spring 16 rebounds and resets, driving the limit rod 503 to push out, while squeezing the outer wall of the mounting hole on the other side of the drive structure 17. like Figure 2 As shown, a drive structure 17 is fixedly connected to the other side of the mounting plate 4, and a stepped tube 18 is slidably connected to the other end of the housing body 1. The stepped tube 18 is designed to rotate and move the nut joint at one end of the stepped tube 18 by rotating the threaded rod 301. At the same time, the threaded surface at one end of the inner wall of the mounting tube 19 is threadedly connected to the threaded tube 302, thereby driving the mounting tube 19 to move. like Figure 1 As shown, the other end of the stepped tube 18 is slidably connected to the mounting tube 19, one end of the mounting tube 19 is fixedly connected to the first set of brushes 20, and one end of the stepped tube 18 is fixedly connected to the second set of brushes 21. The mounting tube 19 facilitates the effective adjustment of the length of the first set of brushes 20.

[0020] The working principle of this utility model is as follows: When it is necessary to improve the processing efficiency of irregularly shaped workpieces with multiple diameters, steps, and conical surfaces, manually rotate the rotating handle 6 to rotate the threaded rod 301. The rotation of the threaded rod 301 drives the nut joint at one end of the stepped tube 18 to rotate and move. At the same time, the threaded surface at one end of the inner wall of the mounting tube 19 is threadedly connected to the threaded tube 302. The threaded tube 302 then drives the mounting tube 19 to move. Through the stable cooperation of the limiting ring 11 and the semi-circular groove 10, the threaded tube 302 and the threaded rod 301 rotate together and move axially along with the stepped tube 18. When it is necessary to improve the installation and replacement of ceramic fiber brushes, the fixing pin assembly 5 is used to... The ceramic fiber brush is fixedly connected to the drive structure 17. First, the sleeve rod 501 is inserted into the mounting hole in the middle of the mounting plate 4 and the inner wall of the mounting hole of the drive structure 17 in sequence. Press the push rod 502 and slide it along the inner wall of the sleeve rod 501, thereby squeezing the spring 16 and pulling the limit rod 503 through the inner wall of the mounting hole of the drive structure 17 and the mounting hole on the surface of the mounting plate 4. Release the push rod 502, the spring 16 rebounds and resets, driving the limit rod 503 out, while squeezing the outer wall of the mounting hole on the other side of the drive structure 17. Then rotate the nut 13 to strengthen the tightness of the sleeve rod 501 and increase the thrust of the limit rod 503, so that the mounting plate 4 and the drive structure 17 are fixedly connected.
