Description

Technical Field

[0001] This utility model relates to the field of bearing processing, specifically to a positioning baffle for turning the outer ring of a bearing. Background Technology

[0002] In today's highly competitive manufacturing environment, bearings, as the core basic components of many mechanical equipment, directly affect the competitiveness of the entire industrial chain in terms of production efficiency and quality. The turning of the bearing outer ring is a key process in bearing manufacturing, which plays a decisive role in the precision and performance of the bearing. In this process, the loading and unloading links serve as the connecting link of the production process, and their efficiency, cost and safety have a profound impact on the entire processing.

[0003] In existing technologies for loading and positioning bearing outer rings, two main operation methods are manual and mechanical. Manual operation is inefficient and cannot meet the needs of large-scale, high-efficiency production. Mechanical handling usually uses a dual-cylinder structure to move and clamp the bearing outer ring. First, a linear cylinder is used to push the bearing to move it to the designated position. Then, a clamping cylinder is used to clamp and fix the bearing. Finally, a motor is used to move the bearing to the target location. However, this design of dual cylinders and motors will significantly increase the overall production cost.

[0004] In actual production applications, through continuous exploration and practice, it has been found that using a single cylinder equipped with a motor to rotate can also achieve the task of handling and clamping the outer ring of the bearing. This method reduces the use of clamping cylinders and effectively reduces equipment costs. In addition, after the outer ring of the bearing is processed, there will be a certain degree of wear during the bearing unloading process. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a positioning baffle for machining the outer ring of a bearing. When the cylinder output end drives the connecting block to approach the material loading assembly, the second connecting rope tightens, bringing the two clamps closer together and indirectly relaxing the first connecting rope. Under the action of the first spring, the magnetic column extends to attract the outer ring of the bearing. Afterward, the cylinder output end moves back, the second connecting rope is no longer tightened, and the two clamps separate under the action of the second spring to clamp the outer ring of the bearing. At the same time, the first connecting rope tightens, causing the magnetic column to retract and no longer attract. By the displacement of the cylinder output end, the attraction and clamping actions are cleverly switched to achieve loading and unloading material handling, while also reducing additional equipment costs.

[0006] The objective of this utility model is achieved through the following technical solution: The bearing outer ring turning positioning baffle includes a turning machine housing, a first fixing block fixedly connected to the turning machine housing, a second fixing block fixedly connected to the turning machine housing, a movable stage disposed next to the turning machine housing, and a first groove formed in the turning machine housing; it also includes a rotary clamping assembly mounted on the turning machine housing, a first drive assembly mounted on the second fixing block, a material loading assembly mounted on the turning machine housing, a first slide assembly mounted on the movable stage, a second slide assembly mounted on the output end of the first slide assembly, a cutter mounted on the output end of the second slide assembly, and a positioning clamping assembly mounted on the output end of the first drive assembly; The first drive assembly includes a second servo motor mounted on the second fixed block and a rotating arm mounted on the output end of the second servo motor. The positioning clamping assembly is mounted on the rotating arm. The second servo motor is used to drive the positioning clamping assembly to move between the loading assembly and the rotating clamping assembly. The positioning and clamping assembly includes a cylinder mounted on a rotating arm, a connecting block mounted on the output end of the cylinder, a third limiting sleeve, a second limiting sleeve and a first limiting sleeve mounted on the connecting block, a magnetic column slidably connected to the second limiting sleeve, a fixing ring mounted on the magnetic column, a first spring connected to the second limiting sleeve and the fixing ring, a second spring mounted on the third limiting sleeve, a clamp mounted on the second spring, a second connecting rope connected between the clamp and the cylinder, and a first connecting rope connected between the magnetic column and the clamp. The cylinder is used to drive the connecting block to move closer to or away from the material loading assembly in the horizontal direction.

[0007] In one optional embodiment, the first connecting rope is threaded onto the third limiting sleeve, and the second connecting rope is threaded onto the first limiting sleeve.

[0008] In one optional embodiment, the rotary clamping assembly includes a first servo motor mounted on a first fixed block, a first synchronous pulley mounted on the output end of the first servo motor, a bearing rotatably connected to a first groove, a rotary joint rotatably connected to the bearing, a second synchronous pulley mounted on the rotary joint, a transmission belt sleeved on the second synchronous pulley and the first synchronous pulley, and an eight-jaw chuck mounted on the output end of the rotary joint. The first servo motor is used to drive the eight-jaw chuck on the output end of the rotary joint to rotate.

[0009] In one optional embodiment, the material loading assembly includes a loading shell mounted on the lathe housing, a second groove formed on the loading shell, and a loading slot. When the bearing outer ring is placed on the loading shell, the outer ring component slides along the trajectory and is stacked at the bottom of the loading slot.

[0010] In one optional embodiment, the first slide assembly includes two first limiting slide rails mounted on a moving platform, a first slide plate slidably connected to the two first limiting slide rails, a third servo motor mounted on the moving platform, and a first lead screw mounted on the output end of the third servo motor. The first slide plate and the first lead screw are threadedly connected, and the third servo motor is used to drive the first slide plate to move horizontally closer to or away from the turning machine housing.

[0011] In one optional embodiment, a connecting rod is installed at one end of the first slide plate near the machine housing, and a feeding box is installed at the other end of the connecting rod. The feeding box is installed at an angle on the connecting rod, and the first slide plate is used to drive the feeding box to move synchronously with it.

[0012] In one optional embodiment, the second slide assembly includes two second limiting slide rails mounted on the first slide plate, a second slide plate slidably connected to the two second limiting slide rails, a fourth servo motor mounted on the first slide plate, and a second lead screw mounted on the output end of the fourth servo motor. The second slide plate and the second lead screw are threadedly connected, and the fourth servo motor is used to drive the cutter on the second slide plate to move along a set trajectory direction.

[0013] In one optional embodiment, a groove is provided on the housing of the turning machine below the eight-jaw chuck, and the feed box is slidably placed in the groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When the cylinder output end drives the connecting block close to the material loading assembly, the second connecting rope tightens, causing the two clamps to move closer together, indirectly loosening the first connecting rope. Under the elastic action of the first spring, the magnetic column extends outward to attract the outer ring of the bearing. Then, the cylinder output end drives the connecting block to move towards the cylinder, the second connecting rope is untied, and the two clamps move away from each other to hold the outer ring of the bearing under the action of the second spring. At the same time, the first connecting rope tightens, causing the magnetic column to retract and not attract the outer ring of the bearing. Through the displacement generated by the output end when the cylinder is opened, the conversion between adsorption and clamping actions is cleverly realized, completing the loading and unloading of materials and reducing additional equipment costs.

[0015] 2. When loading, the first slide moves away from the turning machine housing and pulls out the unloading box to support the outer ring of the bearing that has been machined on the eight-jaw chuck. During machining, the first slide moves the cutting tool so that the unloading box is placed in the groove below the turning machine housing to prevent the cut material from falling into the unloading box. The inclined unloading box allows the outer ring of the bearing to slide smoothly to the designated collection position by its own weight, avoiding damage.

[0016] 3. The outer ring of the bearing to be machined is placed into the loading groove in the loading shell and guided by gravity to slide down and accumulate in the shell. Combined with the motion trajectory set by the positioning and clamping components, the work of quick filling clamping can be realized. Attached Figure Description

[0022] Please refer to Figures 1-6 This utility model provides an embodiment comprising: a turning machine housing 1, a first fixing block 101 fixedly connected to the turning machine housing 1, a second fixing block 102 fixedly connected to the turning machine housing 1, a movable stage 6 disposed beside the turning machine housing 1, and a first groove 103 formed on the turning machine housing 1; characterized in that: it further comprises a rotary clamping assembly mounted on the turning machine housing 1, a first driving assembly mounted on the second fixing block 102, a material loading assembly mounted on the turning machine housing 1, a first slide assembly mounted on the movable stage 6, a second slide assembly mounted on the output end of the first slide assembly, a cutter 609 mounted on the output end of the second slide assembly, and a positioning clamping assembly mounted on the output end of the first driving assembly; The first drive assembly includes a second servo motor 4 mounted on the second fixed block 102 and a rotating arm 401 mounted on the output end of the second servo motor 4. The positioning clamping assembly is mounted on the rotating arm 401. The second servo motor 4 is used to drive the positioning clamping assembly to move between the loading assembly and the rotating clamping assembly. The positioning and clamping assembly includes a cylinder 5 mounted on a rotating arm 401, a connecting block 501 mounted on the output end of the cylinder 5, a third limiting sleeve 507, a second limiting sleeve 503 and a first limiting sleeve 502 mounted on the connecting block 501, a magnetic column 504 slidably connected to the second limiting sleeve 503, a fixing ring 506 mounted on the magnetic column 504, a first spring 505 connected to the second limiting sleeve 503 and the fixing ring 506, a second spring 508 mounted on the third limiting sleeve 507, a clamp 509 mounted on the second spring 508, a second connecting rope 511 connecting the clamp 509 and the cylinder 5, and a first connecting rope 510 connecting the magnetic column 504 and the clamp 509. The cylinder 5 is used to drive the connecting block 501 to move closer to or further away from the material loading assembly in the horizontal direction.

[0023] In a preferred embodiment of this invention, the outer ring of the bearing is slidably stacked in the loading assembly. The second servo motor 4 is activated, causing its output end rotating arm 401 to move the positioning clamping assembly. When its output end faces the loading assembly, the output end of the cylinder 5 drives the connecting block 501 closer to the loading assembly, and the second connecting rope 511 is tightened, thereby bringing the two clamps 509 closer together, indirectly relaxing the first connecting rope 510. This allows the magnetic column 504 to extend outward through the elasticity of the first spring 505, thereby adsorbing the outer ring of the bearing. Then, the second servo motor 4 is activated, driving the positioning clamping assembly to rotate downward, and at the same time, the cylinder 5 is activated, driving the connecting block 501... Moving towards cylinder 5, the second connecting rope 511 is untensioned, causing the two clamps 509 to move away from each other due to the force of the second spring 508, thereby clamping the outer ring of the bearing. At the same time, the first connecting rope 510 is tightened, causing the magnetic column 504 to retract and not attract the outer ring of the bearing. Then, by opening cylinder 5, the outer ring of the bearing is placed on the rotating clamping assembly for clamping. Then, the second servo motor 4 drives cylinder 5 to reset, and the first slide assembly and the second slide assembly drive the cutter 609 to move, thereby performing turning work. The positioning and clamping of the outer ring of the bearing is achieved by using the displacement generated at the output end of cylinder 5 when it is opened, which can effectively reduce costs.

[0024] In a preferred embodiment of this utility model, the first connecting rope 510 is threaded onto the third limiting sleeve 507, and the second connecting rope 511 is threaded onto the first limiting sleeve 502. The first connecting rope 510 is connected between the magnetic column 504 and the clamping sleeve 509. After being threaded onto the third limiting sleeve 507, the third limiting sleeve 507 can provide a guide track for the movement of the first connecting rope 510. When the magnetic column 504 and the clamping sleeve 509 move relative to each other, the first connecting rope 510 can only move along the trajectory of the preset hole or groove on the third limiting sleeve 507, thereby ensuring the accuracy and stability of the relative movement between the magnetic column 504 and the clamping sleeve 509, avoiding deviation or shaking, and ensuring that the positioning and clamping assembly can accurately complete the clamping and positioning actions. The second connecting rope 511 works in the same way as the first limiting sleeve 502.

[0025] In a preferred embodiment of this utility model, the rotary clamping assembly includes a first servo motor 2 mounted on a first fixed block 101, a first synchronous pulley 201 mounted on the output end of the first servo motor 2, a bearing 202 rotatably connected to a first groove 103, a rotary joint 203 rotatably connected to the bearing 202, a second synchronous pulley 204 mounted on the rotary joint 203, a transmission belt 205 sleeved on the second synchronous pulley 204 and the first synchronous pulley 201, and an eight-jaw chuck mounted on the output end of the rotary joint 203. 206. The first servo motor 2 is used to drive the eight-jaw chuck 206 on the output end of the rotary joint 203 to rotate. The output end of the air pump is connected to the input end of the rotary joint 203 to control the clamping of the bearing outer ring by the eight-jaw chuck 206. By turning on the first servo motor 2, the output end of the first servo motor 2 drives the first synchronous pulley 201 to drive the second synchronous pulley 204 on the transmission belt 205 to rotate, thereby causing the rotary joint 203 to drive the eight-jaw chuck 206 on its output end to rotate, so as to perform subsequent turning operations.

[0026] In a preferred embodiment of this utility model, the material loading assembly includes a loading shell 3 mounted on the lathe housing 1, a second groove 301 and a loading groove 302 opened on the loading shell 3. When the bearing outer ring is placed on the loading shell 3, the outer ring slides along the track and stacks at the bottom of the loading groove 302. The bearing outer ring is placed from the loading groove 302 on the loading shell 3, and the bearing outer ring falls into the loading groove 302 and slides down. The stacking condition of the bearing outer ring can be checked through the second groove 301, which facilitates the subsequent positioning and clamping assembly for transportation.

[0027] In a preferred embodiment of this utility model, the first slide assembly includes two first limiting slide rails 601 mounted on the moving stage 6, a first slide plate 602 slidably connected to the two first limiting slide rails 601, a third servo motor 603 mounted on the moving stage 6, and a first lead screw 604 mounted on the output end of the third servo motor 603. The first slide plate 602 and the first lead screw 604 are threadedly connected. The third servo motor 603 is used to drive the first slide plate 602 to move horizontally closer to or away from the turning machine housing 1. A connecting rod 7 is installed at one end of the slide plate 602 near the machine housing 1, and a feeding box 701 is installed at the other end of the connecting rod 7. The feeding box 701 is installed at an angle on the connecting rod 7. The first slide plate 602 is used to drive the feeding box 701 to move synchronously with it. The second slide assembly includes two second limit slide rails 605 installed on the first slide plate 602, a second slide plate 608 slidably connected to the two second limit slide rails 605, a fourth servo motor 606 installed on the first slide plate 602, and a fourth servo motor 608 installed on the fourth servo... The second lead screw 607 on the output end of motor 606, the second slide plate 608 and the second lead screw 607 are threadedly connected. The fourth servo motor 606 is used to drive the cutter 609 on the second slide plate 608 to move along a set trajectory. A groove is opened on the turning machine housing 1 below the eight-jaw chuck 206. The unloading box 701 is slidably placed in the groove. The first slide assembly is opened by the third servo motor 603 to drive the second lead screw 607 to rotate, thereby displacing the first slide plate 602. The second slide plate is moved by the fourth servo motor. When the motor 606 is turned on, it drives the second lead screw 607 to rotate, thereby displacing the second slide plate 608. The displacement of both adjusts the position of the cutter 609. When loading, the first slide plate 602 moves away from the turning machine housing 1, thereby pulling out the unloading box 701 to support the outer ring of the bearing that has been machined on the eight-jaw chuck 206. When machining, the first slide plate 602 conveys the displacement of the cutter 609, so that the unloading box 701 is placed in the groove below the turning machine housing 1 to prevent the cut material from falling into the unloading box 701.

[0028] The first drive assembly mainly consists of a second servo motor 4 and a rotating arm 401. The second servo motor 4 can be replaced with a linear motor, which is installed at the upper end of the turning machine housing 1. The specific transmission structure is as follows: a shaft is connected to the rotating arm 401, and a toothed groove is opened on the outer wall of the shaft; at the same time, a rack is connected to the output end of the linear motor. When working, the linear motor is turned on. Since the rack and the toothed groove mesh with each other, the linear motion of the linear motor is converted into the rotational motion of the shaft through this meshing structure, which in turn drives the rotating arm 401 to rotate. Compared with the drive method of using the unreplaced second servo motor 4, this drive form with a meshing structure and a linear motor has more advantages in terms of running accuracy and can achieve more precise drive control.

[0029] The screw drive structure on the first and second slide assemblies can also be replaced by a linear servo motor connected to the input end of the slide. Compared with the screw drive structure, it has the advantages of high speed, high precision and high efficiency.

[0030] Working principle: First, the outer rings of the bearings are placed sequentially on the loading shell 3, and then they slide down and stack according to the shape of the loading groove 302. The second servo motor 4 is turned on, causing the output end rotating arm 401 to move the positioning clamping assembly to face the loading assembly. The output end of the cylinder 5 drives the connecting block 501 to approach the loading assembly. The second connecting rope 511 is tightened, causing the two clamps 509 to move closer to each other. The first connecting rope 510 is loosened, and the magnetic column 504 extends outward under the action of the first spring 505 to attract the outer rings of the bearings. Then, the second servo motor 4 drives the positioning clamping assembly to rotate downward. At the same time, the cylinder 5 drives the connecting block 501 to move towards itself. The second connecting rope 511 is untightened, and the two clamps 509 move away from each other under the action of the second spring 508 to clamp the outer rings of the bearings. The first connecting rope 510 is tightened, causing the magnetic column 504 to retract and not attract the outer rings of the bearings.

[0031] Then, cylinder 5 places the outer ring of the bearing on the rotary clamping assembly, connects the output end of the air pump to the input end of the rotary joint 203 to control the eight-jaw chuck 206 to clamp the outer ring of the bearing, turns on the first servo motor 2, and its output end drives the first synchronous pulley 201 to rotate the second synchronous pulley 204 via the transmission belt 205, thereby causing the rotary joint 203 to drive the eight-jaw chuck 206 to rotate. Subsequently, the second servo motor 4 drives cylinder 5 to reset.

[0032] The third servo motor 603 is turned on to drive the first lead screw 604 to rotate, causing the first slide table 602 to move horizontally towards the turning machine housing 1 on the first limit slide rail 601. The fourth servo motor 606 is turned on to drive the second lead screw 607 to rotate, causing the second slide plate 608 to move on the second limit slide rail 605. The two work together to make the cutter 609 mounted on the output end of the second slide plate 608 move along a predetermined trajectory to perform turning work. When loading, the first slide plate 602 moves away from the turning machine housing 1 and pulls out the inclined unloading box 701 connected to the connecting rod 7 at the end near the turning machine housing 1 to support the outer ring of the bearing processed on the eight-jaw chuck 206. When processing, the first slide plate 602 conveys the displacement of the cutter 609 so that the unloading box 701 is placed in the groove below the turning machine housing 1 to prevent the cut material from falling into the unloading box 701.

[0033] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.

[0034] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
