Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a spindle taper hole cleaning device. Background Technology

[0002] In the operation and maintenance system of machine tool spindles, the spindle taper hole serves as the core interface connecting the spindle with fixtures, cutting tools, and other accessories. Its cleanliness and precision directly affect the overall machining stability of the machine. Since the spindle taper hole needs to mate with tool holders, and different types of products require tool changes, the tool holders are frequently changed within the spindle taper hole. Therefore, metal shavings, dust, and oxide residues inevitably get trapped. These impurities mix with cutting fluid or water mist from the air, gradually forming scale on the hole wall. The presence of this scale directly threatens assembly accuracy and hole wall safety; therefore, regular cleaning of the machine tool spindle taper hole is necessary.

[0003] Currently, cleaning the spindle taper bore mainly relies on the sponge or cleaning cloth fixed on the cleaning rod to remove dirt. However, using a sponge or cleaning cloth still has the following two problems. On the one hand, the cleaning ability of the sponge or cleaning cloth will be reduced after some impurities adhere to it, which may result in impurities remaining after cleaning the taper bore. On the other hand, impurities will adhere to the surface of the sponge or cleaning cloth during cleaning, and some hard impurities may scratch the inner wall of the spindle taper bore during cleaning.

In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] like Figure 1As shown, one embodiment of this utility model provides a spindle taper hole cleaning device for cleaning spindle taper holes. Specifically, the spindle taper hole cleaning device of this application removes impurities adhering to the inner wall of the spindle taper hole using a scraper in conjunction with a vacuum cleaner-like method. Compared to existing methods that use sponges or cleaning cloths to adhere impurities, the spindle taper hole cleaning device provided in this application has a better cleaning effect and can prevent impurities from scratching the inner wall of the spindle taper hole during cleaning.

[0022] In detail, the spindle taper bore cleaning device includes a tapered body 1 and a cylindrical handle 3 fixedly connected to the tapered body 1. The handle 3 is used by the user to hold and operate the device so as to insert the tapered body 1 into the spindle taper bore for cleaning. The tapered body 1 is provided with a scraper assembly 2, which includes multiple scrapers. When the user rotates the handle 3, the tapered body 1 can be rotated synchronously, thereby causing the scrapers to scrape off the impurities attached to the inner wall of the spindle taper bore.

[0023] Further reference Figure 2 and Figure 3 The spindle taper bore cleaning device also includes an air suction mechanism 4. A cleaning cavity 10 is formed inside the tapered body 1, and a plurality of cleaning holes 12 are formed on the side wall 11 of the cleaning cavity 10. The air suction mechanism 4 is mounted on the handle 3 and can draw air into the cleaning cavity 10, so that impurities scraped off from the inner wall of the spindle taper bore by the scraper can be drawn into the cleaning cavity 10 from outside the tapered body 1 through the cleaning holes 12, thereby preventing impurities from accumulating on or near the scraper, resulting in incomplete cleaning or impurities scratching the inner wall of the spindle taper bore.

[0024] Preferably, the spindle taper hole cleaning device further includes a filter screen 5, which is disposed at the first outlet 101 of the cleaning cavity 10 to trap impurities sucked into the cleaning cavity 10, so as to facilitate subsequent cleaning of the spindle taper hole cleaning device.

[0025] Specifically, further integration Figure 3 and Figure 4 Multiple T-shaped grooves 111 are formed on the sidewall 11 of the conical body 1. The scraper is engaged in the corresponding T-shaped groove 111 and thus fixed to the conical body 1. Furthermore, the scraper is integrally formed and includes a engaging part 201 and a scraping part 202. The engaging part 201 is engaged in the T-shaped groove 111, and the scraping part 202 is exposed on the outside of the conical body 1 to contact the inner wall of the spindle conical hole.

[0026] Preferably, the scraper is made of silicone material, which on the one hand will not scratch the inner wall of the spindle taper hole, and on the other hand can make better contact with the inner wall of the spindle taper hole so as to better scrape off the impurities attached to the inner wall of the spindle taper hole.

[0027] Key reference Figure 1 , Figure 3 and Figure 5 Multiple cleaning holes 12 are arranged in multiple rows, each row including multiple cleaning holes 12 evenly arranged along the axial direction of the conical body 1, and the multiple rows of cleaning holes 12 are evenly arranged around the circumference of the conical body 1, so that impurities can be more evenly sucked into the cleaning cavity 10 and the cleaning holes 12 can be avoided from being blocked.

[0028] Furthermore, we will focus on referring to Figure 5 The cleaning hole 12 is also conical and gradually expands outward from the axis of the conical body 1 to form a trumpet shape, so as to better draw in impurities.

[0029] In addition, we should focus on referring to Figure 3 Each of the aforementioned cleaning holes 12 is provided with a scraper. This arrangement allows the scraper to remove impurities, which are then sucked into the cleaning cavity 10 by the cleaning hole 12 adjacent to the scraper. This prevents impurities from staying on the outer surface of the conical body 1 for too long, which could damage the inner wall of the spindle conical hole, or from accumulating too much impurity and being unable to be sucked in.

[0030] Furthermore, the scrapers within the scraper assembly 2 can be divided into multiple first scrapers 21 and multiple second scrapers 22 according to different installation positions. The first scrapers 21 are positioned relatively close to the upper end face 1a of the conical body 1, while the second scrapers 22 are positioned relatively away from the upper end face 1a of the conical body 1. The first scrapers 21 and second scrapers 22 are distributed sequentially at intervals along the circumference of the conical body 1, and in the axial direction of the conical body 1, the first scrapers 21 and second scrapers 22 are at least partially offset. After the scrapers scrape off the impurities, the impurities will first adhere to the scrapers. When the impurities accumulate to a length exceeding the length of the scrapers, they will detach from the scrapers and be sucked into the cleaning hole 12. This staggered arrangement of the first scrapers 21 and second scrapers 22 effectively prevents impurities from adhering to the scrapers for a long time without being sucked away, thereby improving cleaning efficiency.

[0031] Preferably, after prolonged use, the scraper will experience a certain degree of wear. To facilitate replacement, the first scraper 21 can be inserted or removed from the insertion port 111a exposed on the upper end face 1a of the conical body 1 through the T-shaped groove 111, and the second scraper 22 can be inserted or removed from the guide groove 112 formed on the lower end 1b of the conical body 1, which extends from the T-shaped groove 111.

[0032] Optionally, the spindle tapered bore cleaning device further includes an end cap 6, which is disposed at the second outlet 102 of the cleaning cavity 10 and fixedly connected to the tapered body 1 to prevent the first scraper 21 from detaching from the tapered body 1. In this embodiment, the first outlet 101 and the second outlet 102 are located at the axial ends of the cleaning cavity 10, respectively. Figure 5The end cap 6 is integrally molded and made of rubber. It includes a circular cap body 60 and a blocking block 61 and an elastic buckle 62 extending downward from the cap body 60. The blocking block 61 is annular to abut against all the first scrapers 21. The elastic buckle 62 includes a connecting post 620 and an annular protrusion 621. The annular protrusion 621 has a chamfer 622. During installation, the annular protrusion 621 can be aligned with the second outlet 102 and inserted. Since the end cap 6 is integrally molded and made of rubber, the elastic buckle 62 has a certain elasticity. When the chamfer 622 abuts against the inner wall forming the second outlet 102, the annular protrusion 621 will deform and be inserted into the second outlet 102. When the annular protrusion 621 moves to be fully contained in the cleaning cavity 10, it will return to its original shape and abut against the upper wall 10a forming the cleaning cavity 10, thus fixing the end cap 6 to the conical body 1.

[0033] Optionally, the elastic buckle 62 is provided with an elastic groove 623 so that the elastic buckle 62 can deform more, so that the elastic buckle 62 can be inserted into the second outlet 102.

[0034] Furthermore, a connecting boss 13 is provided on the side wall 11 of the conical body 1, and the connecting boss 13 is annular. Threads are formed on both the inner peripheral wall 130 and the outer peripheral wall 132 of the connecting boss 13. The aforementioned handle 3 is threadedly connected to the outer peripheral wall 132, and the suction mechanism 4 is threadedly connected to the inner peripheral wall 130.

[0035] Specifically, combining Figure 6 The handle 3 is a hollow columnar structure with openings at both ends. A first mounting space 30 is formed inside it. An internal thread is formed on the side wall of the first mounting space 30, which can mate with the thread on the outer peripheral wall 132 of the connecting boss 13. When the handle 3 is threadedly connected to the connecting boss 13, the first mounting space 30 is connected to the cleaning cavity 10. The above-mentioned suction mechanism 4 is set in the first mounting space 30 to evacuate the cleaning cavity 10. The structure is compact, which helps to reduce the overall size of the device.

[0036] Furthermore, we will focus on referring to Figure 2 , Figure 3 and Figure 6 The suction mechanism 4 includes a mechanism assembly 46 and a battery assembly 47 electrically connected to the mechanism assembly 46. A fixing plate 31 is formed inside the handle 3, and the fixing plate 31 divides the first mounting space 30 into a mechanism space 301 and an electrical space 302 along the axis of the handle 3. The mechanism assembly 46 and the battery assembly 47 are respectively disposed in the mechanism space 301 and the electrical space 302 to facilitate the subsequent replacement of the battery 470.

[0037] In detail, the mechanism component 46 includes an impeller 40, a motor 41, a bearing housing 42, and a rotating shaft 43. One end of the bearing housing 42 has an external thread that engages with the threaded inner peripheral wall 130 of the connecting boss 13, allowing the bearing housing 42 to be threadedly connected to the inner peripheral wall 130 of the connecting boss 13. The other end of the bearing housing 42 is fixed to the motor 41. The rotating shaft 43 passes through the bearing housing 42 and is rotatably connected to the bearing housing 42 via a bearing 45. One end of the rotating shaft 43 is drive-connected to the motor 41, and the other end is fixedly connected to the impeller 40, enabling the motor 41 to drive the impeller 40 to rotate and evacuate the cleaning cavity 10.

[0038] Preferably, the bearing housing 42 forms a bearing chamber 420 and a second mounting space 422. The bearing 45 is sleeved on the rotating shaft 43 and installed in the bearing chamber 420. The impeller 40 is disposed in the second mounting space 422 and sleeved on one end of the rotating shaft 43 that protrudes into the second mounting space 422. A first locking nut 471 is also provided at this end of the rotating shaft 43. The locking nut 471 is threadedly fixed to the end of the rotating shaft 43, thereby abutting the impeller 40 between the locking nut 471 and the locking platform 430 of the rotating shaft 43, thus fixing the impeller 40 to the rotating shaft 43 and facilitating disassembly and maintenance. In addition, a bearing end cap 431 is circumferentially sleeved on the locking platform 430, forming a receiving groove 423 on the side wall of the bearing chamber 420. The bearing end cap 431 is interference-fitted into the receiving groove 423 to prevent dirt from entering the bearing chamber 420 and affecting the rotation of the rotating shaft 43.

[0039] Optional, combined Figure 7 The mechanism component 46 also includes a motor bracket 48. One end of the motor bracket 48 is fixedly connected to the bearing seat 42 by a plurality of first screws 481, and the other end is fixedly connected to the motor 41 by a plurality of second screws 482. The motor bracket 48 is hollow, and the output shaft 410 of the motor 41 is disposed inside the motor bracket 48 and is connected to the other end of the rotating shaft 43 by a coupling 49. The hollow design of the motor bracket 48 allows the operator to visually observe the connection between the output shaft 410 and the rotating shaft 43 during installation, facilitating installation and also meeting the requirements of lightweight design.

[0040] Furthermore, in the axial direction of the shaft 43, the upper end of the bearing 45 abuts against the upper limit wall 420a forming the bearing chamber 420. A second locking nut 472 is also threaded onto the shaft 43, and the second locking nut 472 abuts against the lower end of the bearing 45, thereby restricting the displacement of the bearing 45 in the axial direction of the shaft 43.

[0041] Furthermore, the aforementioned filter screen 5 is disposed within the connecting boss 13. Specifically, a groove 131 is formed on the inner peripheral wall 130 of the connecting boss 13, and a removable retaining spring 51 is engaged within the groove 131. The filter screen 5 abuts against the retaining spring 51 and the bottom surface 110 of the side wall 11. The filter screen 5 is fixed in place by the retaining spring 51, thus detachably fixing the filter screen 5 within the connecting boss 13 for easy replacement.

[0042] In addition, combined Figure 8 and Figure 9 To facilitate airflow, a first through hole 421 is formed on the bearing housing 42, with the air inlet 421a of the first through hole 421 located directly below the impeller 40, and the air outlet 421b of the first through hole 421 positioned perpendicular to the axial direction of the bearing housing 42. A second through hole 310 is formed on the fixing plate 31, and a third through hole 320 is formed on the bottom cover 32 forming the electrical space 302. When the impeller 40 rotates, the airflow sequentially flows through the cleaning hole 12, the filter screen 5, the impeller 40, the first through hole 421, the second through hole 310, and the third through hole 320, thus completing the circulation.

[0043] Finally, the aforementioned battery assembly 47 includes a battery 470, a positive contact plate, and a negative contact plate, which are respectively fixedly mounted on the fixing plate 31 and the bottom cover 32. The bottom cover 32 is threadedly connected to the handle 3, and a spring 321 is integrated on the negative contact plate to press the battery 470.

[0044] This utility model provides a spindle taper hole cleaning device that uses a scraper assembly 2 composed of multiple silicone scrapers in conjunction with an air suction mechanism 4 to remove impurities from the inner wall of the spindle taper hole, improving the cleaning effect and preventing impurities from scratching the inner wall. Furthermore, a filter screen 5 is installed at the first outlet 101 of the cleaning cavity 10 to trap the sucked-in impurities within the cleaning cavity 10, facilitating subsequent cleaning.

[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
