Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of cutting devices, and in particular, to a bearing ring cutting device. Background Art

[0002] Bearing rings are the core components of rolling bearings. They are mainly used to support the rotating shaft and guide the movement of rolling elements. Their performance directly affects the precision, life and reliability of the bearings. The blanks of bearing rings are usually seamless steel tubes or round steel bars. When producing bearing rings, cutting machines are required to cut the steel tubes or bars placed on them into short annular parts of specific sizes and diameters.

[0003] After cutting the steel pipe or bar, the cut bearing rings will automatically fall onto the blanking plate of the machine tool and then slide into the collection box. However, during the cutting process, a certain amount of debris will be generated. When the number of cuts is large, the debris is easy to slide or splash onto the blanking plate. If a lot of debris accumulates on the blanking plate, it will affect the cut bearing rings from sliding onto the blanking plate into the collection box. Moreover, if a lot of debris accumulates on the blanking plate, the bearing rings that roll down are easy to slide down with some of the debris into the collection box. Therefore, the staff need to perform manual cleaning regularly. Manual cleaning by the staff is not only cumbersome, but also there is a risk of metal debris scratching the staff's skin during cleaning. Summary of the Invention

[0004] To overcome the above-mentioned defects, an embodiment of the present disclosure provides a bearing ring cutting device, which is used to solve the technical problem in the prior art that when cutting the bearing ring, the debris generated will accumulate on the blanking plate, which is troublesome to clean manually and there is a risk of being cut.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a bearing ring cutting device, comprising a cutting machine installed on a base plate, and also comprising a lower hopper, a scraper plate and a collecting assembly. The lower hopper is fixedly installed on the base plate by an inclined support frame, and is used to slide the cut bearing ring down. The scraper plate is set on the inclined scraper assembly through the mounting assembly. The inclined scraper assembly is used to drive the scraper plate to move on the lower hopper to scrape the debris in the lower hopper. The collecting assembly is set on the base plate, and the collecting assembly is connected to the inclined scraper assembly through a connecting assembly. When the scraper plate scrapes the debris, the collecting assembly can move synchronously accordingly to receive the debris and separate the debris and the bearing ring.

[0006] Furthermore, the inclined scraper assembly includes a support cover 1, a reciprocating screw, a motor and a synchronization assembly. The support cover 1 is tiltedly installed on the top of the base plate through a support rod. The reciprocating screw is rotatably installed in the support cover 1, and a matching crescent slider is installed on the reciprocating screw. The motor is installed on the support cover 1, and the output end of the motor is coaxially connected to the reciprocating screw.

[0007] Furthermore, the synchronization assembly includes a support cover 2, a synchronization rod and a synchronization block. The support cover 2 is fixedly installed at an angle on the side of the cutting machine, the synchronization rod is fixedly installed in the support cover 2, and the synchronization block is slidably installed on the synchronization rod.

[0008] Furthermore, the mounting assembly includes a mounting frame and a connecting frame, the bottom ends of the synchronization block and the crescent slider are fixedly mounted with the mounting frame, and the top end of the mounting frame is provided with a placement groove, the connecting frame is detachably mounted in the placement groove of the mounting frame, and the top end of the scraper plate is fixedly mounted on the top ends of the two connecting frames.

[0009] Furthermore, the collection assembly includes a lower slide and a collection box, the lower slide is fixedly mounted on the base plate, the lower slide is an inclined surface, and the inclined surface of the lower slide is provided with two inclined grooves, the collection box is obliquely slidably mounted on the inclined surface of the lower slide, a partition plate is fixedly mounted inside the collection box, and the partition plate divides the interior of the collection box into two cavities.

[0010] Furthermore, the connecting assembly includes a U-shaped frame and a pushing frame, the U-shaped frame is fixedly installed at the bottom ends of the two mounting frames, the two pushing frames are fixedly installed at the bottom end of the U-shaped frame, and the other ends of the two pushing frames are fixedly installed on the sides of the collection box.

[0011] In order to enable the scraper plate to fit and scrape on the lower hopper, further, the inclination angles of the support cover 1, the support cover 2, the lower hopper and the collection box are consistent.

[0012] In order to prevent debris from falling into the interior of the support cover 1 and the support cover 2 during cutting, further, one side of the opening of the support cover 1 and the support cover 2 is opposite to the top surface of the base plate.

[0013] In order to ensure that the scraper plate fits tightly against the interior of the lower hopper after installation, further, when the connecting frame is inserted into the placement groove of the mounting frame, the bottom end of the scraper plate contacts the inner top end of the lower hopper, and at this time, the inclination angle of the scraper plate is consistent with the inclination angle of the lower hopper.

In the present disclosure, when the scraper plate is scraping in the lower hopper, the collection box of the collection assembly can be synchronously driven forward through the connecting assembly, so that the other cavity of the collection box is synchronously moved to the bottom of the lower hopper, thereby scraping the debris into the other cavity of the collection box, thereby achieving separation and placement of the debris and the bearing ring; To sum up, the device can scrape the debris on the lower hopper when there is a lot of debris on the lower hopper through the mutual cooperation between the lower hopper, scraper plate and collection assembly, and simultaneously drive the collection box to move back and forth, so as to separate the debris and bearing rings. This saves manual cleaning time and energy and eliminates the need to collect the debris and bearing rings one by one. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] like Figures 1 to 6 As shown, it shows a bearing ring cutting device in one embodiment of the present disclosure, including a cutting machine tool 2 installed on a base plate 1, and also including a lower hopper 3, a scraper plate 4 and a collecting assembly. The lower hopper 3 is fixedly installed on the base plate 1 by an inclined support frame, and is used to slide the cut bearing ring down. The scraper plate 4 is set on the inclined scraper assembly through the mounting assembly. The inclined scraper assembly is used to drive the scraper plate 4 to move on the lower hopper 3 to scrape the debris in the lower hopper 3. The collecting assembly is set on the base plate 1, and the collecting assembly is connected to the inclined scraper assembly through a connecting assembly. When the scraper plate 4 scrapes the debris, the collecting assembly can move synchronously accordingly to receive the debris, and separate the debris and the bearing ring.

[0026] like Figure 4 As shown, when cutting the bearing ring, the bearing ring is first cut by the cutting machine 2, and the steel pipe is placed on the turntable of the cutting machine 2. The steel pipe is driven to rotate by the turntable, and the cutting knife on the side of the cutting machine 2 can be moved at the same time. The cutting knife cuts the outer wall of the steel pipe, thereby cutting it into bearing rings of appropriate size, and the cutting machine 2 can control the forward movement of the steel pipe during cutting, thereby cutting the longer steel pipe into several bearing rings. This process is controlled by the CNC system. This is a well-known technology and will not be described in detail.

[0027] After the bearing ring is cut off, it falls on the inclined lower hopper 3, and then slides down into one of the cavities of the collection box 15, and the side of the partition plate 16 of the collection box 15 and the side of the discharge end of the lower hopper 3 are located at the same vertical position. Then the steel pipe is cut multiple times, and the multiple bearing rings generated are slid into one of the cavities of the collection box 15 through the lower hopper 3. After multiple cuttings, a lot of debris may accumulate in the lower hopper 3.

[0028] like Figure 2As shown, when there is a lot of debris accumulated in the lower hopper 3, cutting is stopped, and the scraper plate 4 is driven to move on the lower hopper 3 by the inclined scraper assembly, so as to scrape the debris on the lower hopper 3. Before scraping, the scraper plate 4 is first installed on the inclined scraper assembly through the installation assembly. The installation assembly includes a mounting frame 12 and a connecting frame 13. The bottom ends of the synchronization block 11 and the crescent slider 7 are fixedly installed with the mounting frame 12, and the top of the mounting frame 12 is provided with a placement slot. The connecting frame 13 can be detachably installed on the mounting frame. The mounting frame 12 is placed in the placement slot, and the top of the scraper plate 4 is fixedly installed on the top of the two connecting frames 13. The connecting frame 13 is inserted into the placement slot of the mounting frame 12. Because when the connecting frame 13 is inserted into the placement slot of the mounting frame 12, the bottom end of the scraper plate 4 contacts the inner top end of the lower hopper 3, and at this time the inclination angle of the scraper plate 4 is consistent with the inclination angle of the lower hopper 3, and the length of the scraper plate 4 is consistent with the width of the lower hopper 3, then the scraper plate 4 can fit the inside of the lower hopper 3.

[0029] like Figure 2 、 Figure 4 and Figure 5 As shown, after the lamination is completed, the scraper plate 4 is driven to move on the lower hopper 3 by the inclined scraper assembly, so as to scrape the debris. The inclined scraper assembly includes a support cover 5, a reciprocating screw 6, a motor 8 and a synchronization assembly. The support cover 5 is tilted and installed on the top of the base plate 1 through the support rod. The reciprocating screw 6 is rotatably installed in the support cover 5, and a matching crescent slider 7 is installed on the reciprocating screw 6. The motor 8 is installed on the support cover 5, and the output end of the motor 8 is coaxially connected to the reciprocating screw 6. The synchronization assembly is arranged on the side of the cutting machine 2. The synchronization assembly includes a support cover 2 9, a synchronization rod 10 and a synchronization block 11. The support cover 2 9 is tilted and fixedly installed on the side of the cutting machine 2, the synchronization rod 10 is fixedly installed in the support cover 2 9, and the synchronization block 11 is slidably installed on the synchronization rod 10.

[0030] Specifically, the motor 8 is started, and the output end of the motor 8 drives the reciprocating screw 6 to rotate in the support cover 1 5, thereby causing the crescent slider 7 to move on the reciprocating screw 6, and under the connection of the scraper plate 4, the synchronization block 11 on the other side is driven to slide synchronously on the synchronization rod 10, because the scraper plate 4 is moved in contact with the lower hopper 3, thereby scraping the debris in the lower hopper 3, and the opening side of the support cover 1 5 and the support cover 2 9 is opposite to the top surface of the base plate 1, so that the opening of the support cover 1 5 and the support cover 2 9 is flushed downward to prevent debris from entering the support cover 1 5 and the support cover 2 9. It should be added that a thread groove is provided in the crescent slider, and the thread groove is adapted to the external thread of the reciprocating screw 6.

[0031] like Figure 3As shown, when the lower hopper 3 is moved, the collecting assembly can be driven to move synchronously through the connecting assembly, so that the debris is scraped into another cavity of the collecting box 15. The collecting assembly includes a lower slide 14 and a collecting box 15. The lower slide 14 is fixedly mounted on the bottom plate 1. The lower slide 14 is an inclined surface, and the inclined surface of the lower slide 14 is provided with two inclined slide grooves. The collecting box 15 is obliquely slidably mounted on the inclined surface of the lower slide 14. A partition plate 16 is fixedly mounted in the collecting box 15, and the partition plate 16 divides the interior of the collecting box 15 into two cavities. The connecting assembly includes a U-shaped frame 17 and a pushing frame 18. The U-shaped frame 17 is fixedly mounted on the bottom ends of the two mounting frames 12. Two pushing frames 18 are fixedly mounted on the bottom ends of the U-shaped frame 17, and the other ends of the two pushing frames 18 are fixedly mounted on the sides of the collecting box 15.

[0032] Specifically, when the crescent slider 7 and the synchronous block 11 move, they can drive the mounting frame 12 to move synchronously, and the mounting frame 12 drives the U-shaped frame 17 to move, and the U-shaped frame 17 drives the two pushing frames 18 to move. Because the inclination angles of the support cover 1 5, the support cover 2 9, the lower hopper 3 and the collection box 15 are consistent, the pushing frame 18 pushes the collection box 15 to move downward on the lower slide 14. Because the side of the partition plate 16 of the collection box 15 and the side of the discharge end of the lower hopper 3 are in the same vertical position, the scraper plate 4 moves at the same time. , the other cavity of the collecting box 15 is immediately moved to the bottom of the lower hopper 3, so as to ensure that the debris will not fall into the cavity where the bearing ring is placed when falling. After the scraper plate 4 finishes scraping on the lower hopper 3, the rear end of the collecting box 15 moves to the side of the lower hopper 3 to collect the debris, thereby realizing the separation and placement of the debris and the bearing ring. It should be added that when the bearing ring is cut and falls into the collecting box 15, a small amount of debris may fall into the cavity where the bearing ring is placed, but it will not cause a major impact.

[0033] Working principle: When cutting the bearing ring, the bearing ring is first cut by the cutting machine 2. After the bearing ring is cut, the bearing ring falls on the inclined lower hopper 3, and then slides into one of the cavities of the collection box 15. When there is a lot of debris accumulated in the lower hopper 3, the cutting is stopped, and then the connecting frame 13 is inserted into the placement groove of the mounting frame 12, so that the scraper plate 4 fits with the inside of the lower hopper 3. After fitting, the motor 8 is started, and the output end of the motor 8 drives the reciprocating screw 6 to rotate in the support cover 5, so that the crescent slider 7 moves on the reciprocating screw 6. Under the connection of the scraper plate 4, the synchronous block 11 on the other side is driven to slide synchronously on the synchronous rod 10, and the scraper plate 4 moves on the lower hopper 3, thereby scraping the debris in the lower hopper 3.

[0034] As the scraper plate 4 moves, the mounting frame 12 moves synchronously, and the mounting frame 12 drives the U-shaped frame 17 to move, and the U-shaped frame 17 drives the two pushing frames 18 to move, and the pushing frames 18 drive the collecting box 15 to move on the lower slide 14, so that the other cavity of the collecting box 15 moves to the bottom of the lower hopper 3 to collect the debris, thereby realizing the separation and placement of the debris and the bearing ring.

[0035] It should be added that the rotation angle of the support cover 1 5, the support cover 2 9 and the reciprocating screw 6 is less than 15°, and the reciprocating screw 6 is a sliding reciprocating screw 6, which can ensure that the crescent slider 7 can still move on the reciprocating screw 6 when placed at an angle.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not limiting. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, and all of these should be included in the scope of the claims of the present disclosure.
