Technical Field

[0001] This invention belongs to the field of bearing housing processing technology, and particularly relates to a bearing housing cleaning and positioning mechanism. Background Technology

[0002] During the production of bearing housings, dust or oil may adhere to their surface. Therefore, after processing, it is necessary to use methods to clean the contaminants on the surface of the bearing housing to ensure the cleanliness of the bearing surface.

[0003] Existing cleaning machines are equipped with multiple carrier plates for placing bearings. A robotic arm places the bearing seats on the carrier plates, which are connected to chains. Sprockets drive the chains to rotate, enabling the carrier plates to move on the cleaning machine and transfer the bearing seats to the cleaning area, thus achieving the cleaning function. However, existing processing equipment has the following shortcomings: due to the transmission characteristics of sprockets and chains, the instantaneous transmission ratio cannot be guaranteed. Therefore, when the robotic arm places the bearing seats on the carrier plates, it is easy to encounter the problem of misplacement, which affects production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method that can compensate for errors in the chain drive process, accurately position the carrier plate, facilitate the robot arm to place the bearing seat on the carrier plate, and improve production efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides a bearing housing cleaning and positioning mechanism, comprising multiple carrier plates for placing bearing housings, each carrier plate having positioning pins for positioning, the positioning pins being used in groups, and a cleaning port being provided between two positioning pins used in a group, the cleaning port penetrating the carrier plate, and positioning seats being installed at both ends of each carrier plate, the positioning seats being connected to a chain of the equipment, the chain driving the positioning seats to move; each positioning seat having a positioning module for use therewith, the positioning module being connected to the equipment body, the positioning module including a positioning block for use with the positioning seat, the positioning block being connected to a positioning cylinder for driving its movement, the positioning cylinder being connected to the equipment body.

[0006] Furthermore, a support seat is provided between the bearing housing and the carrier plate, and the bearing housing contacts the support seat.

[0007] Furthermore, the support base has a clearance groove on the side near the carrier plate for the flow of cleaning fluid.

[0008] Furthermore, the positioning seat is provided with a rotating shaft that rotates relative to it. The rotating shaft is connected to a switching disk, on which multiple guide posts are evenly installed. Multiple docking plates that cooperate with the guide posts are connected to the chain. Each docking plate has a sliding groove, allowing the guide posts to slide relative to the inner side of the sliding groove. The positioning seat is provided with a limiting pin that engages with the rotating shaft. The limiting pin extends to the inner side of the positioning seat and slides relative to it. One end of the limiting pin has a tooth that engages with the rotating shaft, and the other end is connected to a horizontal plate. The horizontal plate is connected to a sliding pin that slides relative to the positioning seat. One end of the sliding pin is connected to the horizontal plate, and the other end passes through the positioning seat and can contact the positioning block. The horizontal plate is also provided with a sliding rod that slides relative to it. One end of the sliding rod is fixed to the positioning seat, and the middle of the sliding rod is slidably connected to the horizontal plate. The other end of the sliding rod has a boss that limits its sliding range with the horizontal plate, and a spring is provided between the boss and the horizontal plate.

[0009] Furthermore, the guide post is slidable relative to the switching disk. The guide post is connected to a compensation fixing block, which is slidably connected to the switching disk. A compensation groove is provided at the end of the switching disk. A dividing ring is slidably connected to the inner side of the compensation groove. The dividing ring is connected to a compensation guide shaft and is located in the middle of the compensation guide shaft. The end of the compensation guide shaft is connected to the compensation fixing block. Elastic elements are provided on both sides of the dividing ring and are fitted onto the compensation guide shaft. The length of the compensation guide shaft located inside the compensation groove is less than the total length of the compensation groove.

[0010] This invention, through the above structure, sets up multiple carrier plates for placing bearing seats. Each carrier plate is equipped with positioning pins for positioning. The positioning pins are used in groups, with a cleaning port between two pins in a group, the cleaning port penetrating the carrier plate. Positioning seats are installed at both ends of the carrier plates, and the positioning seats are connected to the equipment's chain, which drives the positioning seats to move. Each positioning seat contains a positioning module that works in conjunction with it, and the positioning module is connected to the equipment body. The positioning module includes a positioning block that works with the positioning seat, and the positioning block is connected to a positioning cylinder that drives its movement. The positioning cylinder is also connected to the equipment body. When the robot arm needs to place material onto the carrier plate, it controls the positioning cylinder to extend the positioning block, causing the positioning block to engage with the positioning seat, thereby restricting the position of the carrier plate and achieving the positioning function of the carrier plate. This facilitates the robot arm in placing the bearing seats onto the carrier plate, improves the robot arm's feeding cycle time, and increases production efficiency. Attached Figure Description

Detailed Implementation

[0012] See attached document Figure 1 This invention provides a bearing housing cleaning and positioning mechanism, comprising multiple carrier plates 1 for placing bearing housings 101. Each carrier plate 1 is provided with positioning pins 102 for positioning. The positioning pins 102 are used in groups, and a cleaning port 105 is provided between two positioning pins 102 used in a group. The cleaning port 105 passes through the carrier plate 1. The positioning pins 102 are adapted to the mounting holes of the bearing housings 101. Positioning seats 104 are installed at both ends of the carrier plate 1. The positioning seats 104 are connected to the chain of the equipment. When the sprocket drives the chain to rotate, the chain drives the positioning seats 104 to move, realizing the function of the chain driving the carrier plate 1 to move. A positioning module is provided inside the positioning seat 104 for use with it. The positioning module is connected to the equipment body. When the carrier plate 1 moves to the material unloading position of the robot arm, the positioning module cooperates with the positioning seat 104 to restrict the movement of the positioning seat 104 and the carrier plate 1, facilitating material unloading by the robot arm. The positioning module includes a positioning block 201 that works in conjunction with the positioning base 104. The positioning block 201 is connected to a positioning cylinder 202 that drives its movement. The positioning cylinder 202 is connected to the equipment body.

[0013] Through the above structure, the carrier plate 1 moves slowly under the drive of the chain. When the carrier plate 1 rotates to the unloading position of the robot arm, the positioning cylinder 202 pushes out the positioning block 201, so that the positioning block 201 is placed in the positioning groove of the positioning seat 104. Since the positioning block 201 is connected to the positioning cylinder 202 and the positioning cylinder 202 is connected to the equipment body, the position of the positioning block 201 remains unchanged relative to the equipment body. That is, when the positioning seat 104 contacts the positioning block 201, the positions of the positioning seat 104 and the carrier plate 1 remain unchanged relative to the equipment body. Therefore, the position of the carrier plate 1 is determined, and at this time, the robot arm can correctly place the bearing seat on it onto the positioning pin 102 on the carrier plate 1, thus realizing the unloading function. After the material is unloaded, the positioning cylinder 202 is in the retracted state, releasing the contact between the positioning block 201 and the positioning seat 104; the chain drives the carrier plate 1 to continue moving to the cleaning station, and the cleaning fluid is sprayed out from the cleaning port 105 and comes into contact with the bearing seat 101, removing the dirt on the surface of the bearing seat 101 and realizing the cleaning function of the bearing seat 101.

[0014] Preferred, see Figure 1 and Figure 6 A support seat 103 is provided between the bearing housing 101 and the carrier plate 1. The bearing housing 1 contacts the support seat 103. Since the support seat 103 has a certain thickness, it can keep the bearing housing 101 and the carrier plate 1 at a certain distance, so that the cleaning fluid can contact the lower end of the bearing housing 101, that is, the cleaning fluid contacts the side of the bearing housing 101 near the carrier plate 1, which facilitates cleaning of the lower side of the bearing housing 101 and ensures that the contact surface of the two bearing housings 1 is kept clean.

[0015] See Figure 6 The support base 103 has a relief groove on the side near the carrier plate 1 for the flow of cleaning fluid.

[0016] See Figures 2 to 5 The positioning seat 104 is provided with a rotating shaft 203 that rotates relative to it. The rotating shaft 203 is connected to a switching disk 204. Multiple guide posts 205 are evenly installed on the switching disk 204, that is, the multiple guide posts are evenly distributed along the circumference of the switching disk 204. Multiple docking plates 206 that cooperate with the guide posts 205 are connected to the chain 207. The docking plates 206 are provided with sliding grooves 209, and the guide posts 205 can slide relative to the inner side of the sliding grooves 209. The connection method between the chain 207 and the docking plates 206 can be: the pin 208 passes through the docking plate 206 and then passes through the inner chain plate and the outer chain plate of the chain 207 in sequence to realize the connection between the docking plate 206 and the chain 207.

[0017] See Figure 7 and Figure 8The positioning seat 104 is provided with a limiting pin 210 that can engage with the rotating shaft 203. The limiting pin 210 extends to the inner side of the positioning seat 104 and slides relative to it. One end of the limiting pin 210 is provided with gear teeth that engage with the rotating shaft 203. Similarly, the outer circumference of the rotating shaft 203 is also provided with gear teeth that engage with the limiting pin 210. The other end of the limiting pin 210 is connected to a horizontal plate 212. The horizontal plate 212 is connected to a sliding pin 211 that slides relative to the positioning seat 104. One end of the sliding pin 211... One end is connected to the horizontal plate 212, and the other end of the sliding column 211 passes through the positioning seat 104 and can contact the positioning block 201; the horizontal plate 212 is also provided with a sliding rod 213 that slides relative to it. One end of the sliding rod 213 is fixed to the positioning seat 104, the middle part of the sliding rod 213 is slidably connected to the horizontal plate 212, and the other end of the sliding rod 213 is provided with a boss that limits its sliding range with the horizontal plate 212. A spring 214 is provided between the boss and the horizontal plate 212, and the spring 214 is fitted on the sliding rod 213.

[0018] With the above structure, when the positioning block 201 is not in contact with the positioning seat 104, that is, when the carrier plate 1 does not need to be fed, the spring 214 applies a force to the horizontal plate 212, causing the horizontal plate 212 to move closer to the positioning seat 104. At this time, the limiting pin 210 engages with the rotating shaft 203, preventing the rotating shaft 203 from rotating. The switching disk 204 and the docking plate 206 cannot move relative to each other. When the chain 207 rotates, it can drive the docking plate 206 to rotate. At the same time, the docking plate 206 drives the positioning seat 104 to move through the guide pin 205, the switching disk 204, and the rotating shaft 203, thus realizing the function of the chain 207 driving the carrier plate 1 to move. When the robot needs to feed material, the positioning cylinder 202 pushes... Positioning block 201 approaches positioning seat 104, contacts sliding column 211 and pushes it to move. Sliding column 211 drives horizontal plate 212 to move away from rotating shaft 203. At the same time, horizontal plate 212 drives limiting pin 210 to move away from rotating shaft 203, and spring 214 is compressed. As positioning cylinder 202 extends, the gear teeth at the end of limiting pin 210 can disengage from the gear teeth on rotating shaft 203. At this time, rotating shaft 203 can rotate freely. When chain 207 moves, multiple guide pins 205 on switching disc 204 can alternately contact and slide relative to multiple docking plates 206 on chain 207. Through the above structure, when positioning cylinders 202 on both sides drive positioning block 201 to position positioning seat 104, the chain of the equipment can still rotate, without affecting the operation of other carrier plates 1, thus improving equipment operating efficiency.

[0019] Preferred, see Figure 9The guide post 205 can slide relative to the switching disk 204. The guide post 205 is connected to the compensation fixing block 215, which is slidably connected to the switching disk 204. The end of the switching disk 204 is provided with a compensation groove 217. A dividing ring 218 is slidably connected to the inner side of the compensation groove 217. The dividing ring 218 is connected to the compensation guide shaft 216 and is located in the middle of the compensation guide shaft 216. The end of the compensation guide shaft 216 is connected to the compensation fixing block 215. Elastic elements, such as springs, are provided on both sides of the dividing ring 218. The elastic elements are fitted on the compensation guide shaft 216. The length of the compensation guide shaft 216 inside the compensation groove 217 is less than the total length of the compensation groove 217, so that the compensation guide shaft 216 can move left and right inside the compensation groove 217. Through the above structure, the present invention sets the guide shaft 205 to slide relative to the switching disk 204. When the positioning cylinder 201 positions the carrier plate 1, the chain drives the guide post 205 to move through the docking plate 206, causing the rotating shaft 203 to rotate. Since the chain drive cannot guarantee the instantaneous transmission ratio, when one of the guide posts 205 cannot be aligned with the sliding groove 209 on the docking plate 206, the left and right sliding of the compensation fixing block 215 relative to the switching disk 204 is used to compensate for the deviation between the guide post 205 and the sliding groove 209, so that the guide post 205 can enter the inner side of the sliding groove 209.

[0020] This invention, through the above structure, sets up multiple carrier plates for placing bearing seats. Each carrier plate is equipped with positioning pins for positioning. The positioning pins are used in groups, with a cleaning port between two pins in a group, the cleaning port penetrating the carrier plate. Positioning seats are installed at both ends of the carrier plates, and the positioning seats are connected to the equipment's chain, which drives the positioning seats to move. Each positioning seat contains a positioning module that works in conjunction with it, and the positioning module is connected to the equipment body. The positioning module includes a positioning block that works with the positioning seat, and the positioning block is connected to a positioning cylinder that drives its movement. The positioning cylinder is also connected to the equipment body. When the robot arm needs to place material onto the carrier plate, it controls the positioning cylinder to extend the positioning block, causing the positioning block to engage with the positioning seat, thereby restricting the position of the carrier plate and achieving the positioning function of the carrier plate. This facilitates the robot arm in placing the bearing seats onto the carrier plate, improves the robot arm's feeding cycle time, and increases production efficiency.
