Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, and in particular to a multi-station processing device for bearing rings. Background Technology

[0002] Bearing rings are annular parts of radial rolling bearings with one or more raceways, primarily functioning to ensure the stability and safety of the bearing during normal operation. Utility model patent application number CN202421024484.9 discloses a jig for processing bearing rings, including a base mechanism. A processing mechanism is rotatably mounted on one side of the upper end of the base mechanism. The base mechanism includes a base body, with a rectangular groove on one side of the upper end of the base body. The processing mechanism includes a processing plate, with a circular block fixedly connected to the center of the front surface of the processing plate. A third connecting block is fixedly connected to the center of the front surface of the circular block. Second electric telescopic rods are fixedly connected to both sides of the third connecting block. Arc-shaped blocks are fixedly connected to one side of the two second electric telescopic rods. Limiting clamps are slidably mounted on both ends of the rear side of the processing plate near the center. A circular groove is located at the center of the rear side of the processing plate. The upper end of the base body... A control panel is fixedly connected to one end of the front surface. A first electric telescopic rod is fixedly connected to one side of the upper rear surface of the base body. A first connecting block is fixedly connected to the upper surface of the first electric telescopic rod. A motor protection box is fixedly connected to the upper surface of the first connecting block. A rotating motor is fixedly connected to one side of the inside of the motor protection box. A movable door is hinged to the upper surface of the processing plate. Fixed rods are fixedly connected to both sides of the rear side of the inside of the processing plate near the center. A slide rail is fixedly connected to one side of the inside of the two fixed rods. Linear motors are slidably mounted around the surfaces of multiple slide rails. Fixed columns are fixedly connected to the upper surfaces of the two linear motors. A second connecting block is fixedly connected to the upper surfaces of the two fixed columns. A protective layer is fixedly connected to one side of the two arc-shaped blocks. The outer ring surface of the bearing race is processed first.

The other side of the processing mechanism lacks effective support, making the processing process extremely unstable and affecting the processing quality. Utility Model Content

[0003] This invention aims to solve the problems existing in the prior art by providing a multi-station machining device for bearing rings, which can simultaneously process the inner and outer rings of multiple bearing rings. The same platform facilitates processing, reduces errors, saves time and manpower, improves work efficiency, and enhances stability to ensure processing quality.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: This multi-station processing device for bearing rings includes a first base, a first clamping block, and a second clamping block. A boss is fixedly connected to the top of the first base, and there are two bosses. A first support seat is provided on the top of the boss. A first cylinder is installed on the side of the first support seat. A piston rod is provided at the output end of the first cylinder. A first movable plate is fixedly connected to the side of the piston rod. The first movable plate has an L-shaped structure and extends to the top of the first support seat. The first clamping block is connected to the first movable plate. There are two sets of first cylinders, first movable plates, and first clamping blocks. The two first cylinders are distributed on the first support seat. On the left and right sides of the support, a second support base is provided on the top of the boss. The second support base has an inner groove, and a second cylinder is installed on the side of the inner groove. A piston rod is also provided on the side of the second cylinder, and a second movable plate is fixedly connected to the side of the piston rod. A connecting block is fixedly connected to the top of the second movable plate. An inner hole is opened on the top of the second support base, communicating with the inner groove. The connecting block is inside the inner hole, and a second clamping block is connected to the connecting block. There are two sets of second cylinders, second movable plates, and second clamping blocks. The two second cylinders are distributed on the left and right sides of the inner groove. A second base is provided on the side of the first base, and a third base is provided on the side of the second base. The second base and... The third base is also equipped with first and second clamping blocks. The bearing rings requiring outer ring machining are fitted onto the outside of the two second clamping blocks. The bearing rings requiring inner ring machining are placed at the center of the top of the first support. This process is repeated to place multiple bearing rings. The two first cylinders are then activated to retract, causing the piston rods to retract and move the two first moving plates and the two first clamping blocks towards the center of the top of the first support. The two first clamping blocks clamp and fix the bearing rings. The two second cylinders are then activated to retract, causing the piston rods to retract and move the two second moving plates and the two second clamping blocks away from each other. The second clamping block abuts against the inner wall of the bearing ring in the opposite direction, effectively fixing the bearing ring. Multiple bearing rings are fixed in the same way. While machining the outer rings of multiple bearing rings, the inner rings of multiple bearing rings are also being machined. After the outer and inner rings of multiple bearing rings are machined respectively, the bearing rings on the top of the first and second support seats are swapped and then fixed for machining, so that both the inner and outer rings of each bearing ring are machined. The entire process simultaneously machines the inner and outer rings of multiple bearing rings. The same platform facilitates machining, reduces errors, saves time and manpower, improves work efficiency, and enhances stability to ensure machining quality.

[0005] To further improve the design, the first clamping block has an inner arc groove on its inner side, and the second clamping block has an outer arc surface on its side. The inner arc groove and the outer arc surface are covered with an adhesive layer. The bearing ring is located inside the inner arc groove of the two first clamping blocks to prevent the bearing ring from shifting or detaching. The outer arc surface fits against the inner wall of the bearing ring to increase the force-bearing area and improve stability.

[0006] Further improvements include a first movable hole on the side of the first support base, with a first movable column inside the first movable hole. There are multiple first movable holes and first movable columns, and the multiple first movable columns are connected to the first movable plate. The multiple first movable columns move inside the multiple first movable holes, effectively restricting the movement path of the first movable plate and the first clamping block, thus ensuring the accuracy of the first clamping block.

[0007] To further improve the design, a second movable hole is provided inside the inner groove, and a second movable column is provided inside the second movable hole. There are multiple second movable holes and second movable columns, and multiple second movable columns are connected to a second movable plate. The multiple second movable columns move inside multiple second movable holes, and the movement path of the second movable plate and the second clamping block is effectively restricted, ensuring the accuracy of the second clamping block.

[0008] Further improvements include a baffle frame on the top of the first base, a drain hole on the top of the first base, and an internal groove at the bottom of the first base, which is connected to the drain hole. A collection box is installed inside the internal groove, and a set of moving wheels is installed at the bottom of the collection box. The second and third bases are also equipped with baffle frames, drain holes, internal grooves, and collection boxes. The debris generated during processing is blocked by the baffle frame to prevent it from falling onto the work site. After processing is completed, the debris on the top of the first, second, and third bases is cleaned up, and the debris falls into the collection box through the drain hole for convenient unified treatment later.

[0009] To further improve the design, the top of the drain hole is provided with a first chamfer, the inside of the baffle frame is provided with a second chamfer, the bottom of the boss is provided with a third chamfer, the bottom of the first support base is provided with a fourth chamfer, and the bottom of the second support base is also provided with a fourth chamfer. The first chamfer increases the opening size at the top of the drain hole and improves the passage effect. The second, third, and fourth chamfers reduce dead corners at the edges of the structure and prevent debris and impurities from accumulating.

[0010] Further improvements include a connecting groove on the front side of the first base and a connecting hole on the side of the first base, with the connecting hole connecting to the interior of the connecting groove. There are multiple connecting grooves and connecting holes. Multiple connecting grooves are also provided on the back of the first base. The second and third bases are also provided with multiple connecting grooves and multiple connecting holes. Bolts and nuts are provided inside the connecting grooves. The bolts pass through two connecting holes consecutively. After reaching another connecting groove, the bolts are threadedly connected to the nuts. The first, second, and third bases are assembled using connecting grooves, connecting holes, bolts, and nuts. Assembly is simple and disassembly is easy, facilitating the adjustment of the number of bases and meeting more practical needs.

[0011] Further improvements include the provision of multiple storage slots on the front side of the first base, as well as multiple storage slots on the second and third bases. Bolts, nuts, and bearing rings can be conveniently placed in the storage slots nearby, ensuring effective storage and protection of items. The multiple storage slots also enhance the storage and placement effect.

[0012] The beneficial effects of this utility model are: By slipping the bearing rings whose outer rings need machining onto the outside of the two second clamping blocks, and placing the bearing rings whose inner rings need machining at the center of the top of the first support seat, multiple bearing rings are placed using this method. Then, the two first cylinders are activated to retract, and as the piston rods retract, they move the two first moving plates and the two first clamping blocks towards the center of the top of the first support seat. The two first clamping blocks clamp and fix the bearing rings. Next, the two second cylinders are activated to retract, and as the piston rods retract, they move the two second moving plates away from each other, and the two second clamping blocks move away from each other in opposite directions. By pressing against the inner wall of the bearing ring, the bearing ring is effectively fixed. Multiple bearing rings are fixed in the same way. While machining the outer rings of multiple bearing rings, the inner rings of multiple bearing rings are also being machined. After the outer and inner rings of multiple bearing rings are machined respectively, the bearing rings on the top of the first and second support seats are swapped and then fixed for machining. This ensures that both the inner and outer rings of each bearing ring are machined. The entire process simultaneously machines the inner and outer rings of multiple bearing rings. Machining on the same platform facilitates machining, reduces errors, saves time and manpower, improves work efficiency, and enhances stability to ensure machining quality.

[0013] The debris generated during processing is blocked by the baffle frame to prevent it from falling onto the work site. After processing, the debris on the top of the first, second, and third bases is cleaned up. The debris falls into the collection box through the drain hole for easy unified treatment later. The first chamfer increases the opening size of the drain hole and improves the passage effect. The second, third, and fourth chamfers reduce dead corners at the edges of the structure and prevent debris and impurities from accumulating.

[0014] The first, second, and third bases are assembled using connecting slots, connecting holes, bolts, and nuts. Assembly is simple and disassembly is easy, and the number of bases can be adjusted to meet more practical needs. Bolts, nuts, and bearing rings can be conveniently placed in the storage slots nearby, and items are effectively stored and protected. Multiple storage slots increase the storage capacity.

[0020] In use, the second base 15 is positioned to the side of the first base 1, and the third base 16 is positioned to the side of the second base 15. Multiple connecting slots 32 correspond to each other, and multiple connecting holes 33 correspond to each other. Bolts 34 and nuts 35 are retrieved from the storage slot 36. The bolts 34 pass through two connecting holes 33 consecutively within one of the connecting slots 32, and the nuts 35 are placed in the other corresponding connecting slot.

After the outer and inner rings of multiple bearing rings are processed, the bearing rings on the top of the first support seat 5 and the second support seat 9 exchange positions. Then, the bearing rings are fixed and processed so that both the inner and outer rings of each bearing ring are processed. The entire process processes the inner and outer rings of multiple bearing rings simultaneously. Processing on the same platform facilitates processing, reduces errors, saves time and manpower, improves work efficiency, and enhances stability to ensure processing quality.

The setting of the first chamfer 28 increases the opening size of the top of the drain hole 24 to improve the passage effect. The setting of the second chamfer 29, the third chamfer 30, and the fourth chamfer 31 reduces dead corners at the edge of the structure and prevents debris and impurities from accumulating.
