Description

Technical Field

[0001] This invention relates to the field of workpiece chamfering device technology, specifically a screw rotor journal bearing outer ring treatment device. Background Technology

[0002] In the intelligent manufacturing equipment industry, its manufacturing equipment and processes have the development characteristics of "intelligent control, modular integration, and high collaboration". The outer ring chamfering of bearings is a key process in bearing manufacturing, which directly affects the assembly accuracy, fatigue life and operational reliability of bearings. However, the existing intelligent manufacturing equipment for bearing outer ring chamfering mostly adopts a single-piece clamping mode, relying on manual or robotic arm loading, fixture positioning, and manual or robotic arm unloading. The processing continuity is not high, and there is idle waiting time between processes, resulting in low intermittent processing efficiency of existing equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a screw rotor journal bearing outer ring treatment device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A screw rotor journal bearing outer ring treatment device, comprising:

[0006] The mounting plate has a guide plate 1 and a guide plate 2 mounted on its surface. A material feeding channel is provided between the guide plate 1 and the guide plate 2. The material feeding channel is used to guide the outer ring of the bearing. One end of the mounting plate has a venting groove 1 and two venting grooves 2. The venting grooves 2 are located at both ends of the venting groove 1. Two mounting brackets are fixedly installed below one end of the mounting plate. A cross bracket is mounted on the mounting plate. Two grinding wheels are mounted on the cross bracket.

[0007] A base plate, wherein the mounting bracket is rotatably connected to the base plate, and the angle of the mounting plate is adjustable;

[0008] An interception assembly is installed at one end of a mounting plate. The interception assembly includes a lower positioning roller and an upper positioning roller, which move toward each other.

[0009] A positioning shaft is rotatably connected between two mounting brackets. Two cams are fixedly mounted on the mounting brackets. A drive motor is fixedly mounted on the mounting plate. The output end of the drive motor is connected to one end of the positioning shaft.

[0010] A push assembly is installed on one side of the mounting plate at the middle position. The push assembly includes a squeeze roller, which is used to rotate and squeeze the outer ring of the bearing.

[0011] Furthermore, the interception assembly also includes a support frame, which is fixedly installed below one end of the mounting plate. Slide rods are fixedly installed at both ends of the support frame. The roller shafts of the lower positioning roller and the upper positioning roller are slidably sleeved between the two slide rods. A connecting module is connected between the two ends of the roller shafts of the lower positioning roller and the upper positioning roller.

[0012] Furthermore, both ends of the lower positioning roller shaft are rotatably connected to rolling rings, which are used to contact the cam.

[0013] Furthermore, both ends of the slide rod are fitted with tension springs, one end of the tension spring is fixedly connected to the adjacent roller shaft, and the other end of the tension spring is fixedly connected to the slide rod.

[0014] Furthermore, the connecting module includes a gear, and a cylinder is fixedly installed on one side of the venting groove two on the mounting plate. The gear is rotatably connected to the top of the frame. Both ends of the roller shafts of the lower positioning roller and the upper positioning roller are fixedly connected with toothed rods, and the toothed rods mesh with the adjacent gears.

[0015] Furthermore, the cam is provided with an equidistant portion and a variable-pitch portion.

[0016] Furthermore, the pushing component also includes a fixed base, which is fixedly mounted on the mounting plate. A sliding seat is slidably connected to the fixed base. The extrusion roller is rotatably mounted at one end of the sliding seat. A second drive motor is fixedly mounted on the sliding seat. The output end of the second drive motor is connected to the extrusion roller. A second cylinder is fixedly mounted on the mounting plate. The output end of the second cylinder is fixedly connected to the other end of the sliding seat. The second cylinder is used to drive the sliding seat to tilt and move.

[0017] Furthermore, the guide plate one is fixedly mounted on the mounting plate, the guide plate two is slidably mounted on the mounting plate, and cylinder one is fixedly mounted at both ends of one side of the mounting plate. The output end of cylinder one is fixedly connected to guide plate two, and an upper stop is fixedly mounted at one end of guide plate one.

[0018] Furthermore, two mounting shafts are rotatably mounted on the frame, and the two grinding wheels are respectively mounted at one end of the two mounting shafts. A dual-axis motor is fixedly mounted at the top of the frame, and the output end of the dual-axis motor is rotatably connected to both mounting shafts.

[0019] Furthermore, a manual telescopic rod is rotatably mounted between the other end of the seat plate and the mounting plate, and the length of the manual telescopic rod can be manually adjusted.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting up the interception component and mounting plate, the extrusion roller moves diagonally forward, contacts the inner ring of the bearing outer ring, and pushes the bearing outer ring forward, causing the bearing outer ring to deflect around the lower positioning roller until the edge of the bearing outer ring contacts and is squeezed by the two grinding wheels. The extrusion roller rotates, causing the bearing outer ring to rotate, thereby causing the grinding wheels to chamfer and grind the edge of the bearing outer ring until the bearing outer ring contacts both the lower and upper positioning rollers simultaneously. The grinding of the bearing outer ring by the grinding wheels is completed. Then the extrusion roller moves back to its original position, and the bearing outer ring falls back onto the mounting plate, disengaging from the grinding wheels. Then the lower positioning roller moves down, releasing the obstruction on the bearing outer ring. The ground bearing rolls forward past the lower positioning roller. Then the lower positioning roller moves up to block the next bearing outer ring, realizing continuous chamfering of the bearing outer ring, improving the degree of automation and processing efficiency.

[0022] 2. With the installation plate and manual telescopic rod, during the continuous rotation of the cam, when the equidistant part contacts the rolling ring, the grinding wheel contacts and grinds the outer ring of the bearing. Before the equidistant part completely passes the rolling ring, the grinding wheel finishes grinding the outer ring of the bearing. By adjusting the tilt angle of the installation plate, the speed at which the outer ring of the bearing rolls forward is controlled, so that only one outer ring of the bearing can pass the lower positioning roller during the time when the variable pitch part contacts the rolling ring. This allows the lower positioning roller to release only the chamfered outer ring of the bearing during its downward and then upward movement, facilitating the sequential processing and release of the outer rings of the bearing.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 7In this embodiment of the invention, a screw rotor journal bearing outer ring processing device includes a base plate 100, a mounting plate 200, an interception assembly 300, a positioning shaft 400, and a pushing assembly 600. A guide plate 1 210 and a guide plate 220 are mounted on the surface of the mounting plate 200. A discharge channel 250 is provided between the guide plate 1 210 and the guide plate 220 for guiding the bearing outer ring. One end of the mounting plate 200 has a venting groove 1 201 and two venting grooves 202, located at both ends of the venting groove 1 201. Two mounting brackets 240 are fixedly mounted below one end of the mounting plate 200. A crossbeam 700 is mounted on the mounting plate 200, and two grinding wheels 730 are mounted on the crossbeam 700. The frame 240 is rotatably connected to the base plate 100. The angle of the mounting plate 200 is adjustable. The intercepting component 300 is installed at one end of the mounting plate 200. The intercepting component 300 includes a lower positioning roller 310 and an upper positioning roller 320. The lower positioning roller 310 and the upper positioning roller 320 move towards each other. The positioning shaft 400 is rotatably connected between the two mounting frames 240. Two cams 410 are fixedly installed on the mounting frame 240. A drive motor 500 is fixedly installed on the mounting plate 200. The output end of the drive motor 500 is connected to one end of the positioning shaft 400. The pushing component 600 is installed on one side of the middle position of the mounting plate 200. The pushing component 600 includes a squeezing roller 630, which is used to rotate and squeeze the outer ring of the bearing.

[0036] Specifically, the outer ring of the bearing rolls along the feeding channel 250 under the action of gravity. The drive motor 500 drives the positioning shaft 400 to rotate, which in turn drives the cam 410 to rotate, thereby causing the lower positioning roller 310 to move upward. This causes the lower positioning roller 310 to move from the position of the venting groove 201 to above the mounting plate 200. The outer ring of the bearing, rolling downward, simultaneously contacts the surface of the mounting plate 200 and the guide plate 210. The outer ring of the bearing is located below the grinding wheel 730 but does not contact it. Subsequently, the extrusion roller 630 moves diagonally forward, contacts the inner ring of the outer ring of the bearing, and pushes the outer ring of the bearing forward, causing the outer ring of the bearing to deflect around the lower positioning roller 310. The edge of the bearing ring contacts and is pressed by the two grinding rollers 730. The pressing roller 630 rotates, causing the bearing outer ring to rotate, thus making the grinding rollers 730 chamfer the edge of the bearing outer ring until the bearing outer ring simultaneously contacts the lower positioning roller 310 and the upper positioning roller 320. The grinding of the bearing outer ring by the grinding rollers 730 is completed. Then the pressing roller 630 moves back to its original position, and the bearing outer ring falls back onto the mounting plate 200, disengaging from the grinding rollers 730. Then the lower positioning roller 310 moves down, releasing its obstruction to the bearing outer ring. The ground bearing rolls forward past the lower positioning roller 310. Then the lower positioning roller 310 moves up to block the next bearing outer ring, thus achieving continuous chamfering of the bearing outer ring. Example 1

[0037] like Figures 4-8 As shown, in this embodiment, the interception component 300 further includes a support frame 340, which is fixedly installed below one end of the mounting plate 200. Slide rods 330 are fixedly installed at both ends of the support frame 340. The roller shafts of the lower positioning roller 310 and the upper positioning roller 320 are slidably sleeved between the two slide rods 330. A connecting module 360 ​​connects the two ends of the roller shafts of the lower positioning roller 310 and the upper positioning roller 320. Roller rings 311 are rotatably connected to both ends of the roller shaft of the lower positioning roller 310. The roller rings 311 are used to contact the cam 410. Both ends of the slide rods 330 are sleeved... There is a tension spring 350, one end of which is fixedly connected to the adjacent roller shaft, and the other end of which is fixedly connected to the slide bar 330. The connecting module 360 ​​includes a gear 361. A cylinder 230 is fixedly installed on the mounting plate 200 on one side of the venting groove 202. The gear 361 is rotatably connected to the top of the frame 203. Both ends of the roller shafts of the lower positioning roller 310 and the upper positioning roller 320 are fixedly connected to a rack 362. The rack 362 meshes with the adjacent gear 361. The cam 410 is provided with an equidistant part 411 and a variable part 412.

[0038] In this embodiment, when the equidistant portion 411 contacts the rolling ring 311, the lower positioning roller 310 is at its highest position during its vertical movement. The equidistant portion 411 ensures that the lower positioning roller 310 remains at its highest position for a certain period during the continuous rotation of the cam 410. The length of this period can be adjusted by changing the speed of the drive motor 500, ensuring that the length of this period matches the grinding time of the grinding wheel 730 on the bearing outer ring. That is, during the continuous rotation of the cam 410, when the equidistant portion 411 contacts the rolling ring 311, the grinding wheel 730 contacts and grinds the bearing outer ring. The grinding wheel 730 completes grinding the bearing outer ring before the equidistant portion 411 completely passes the rolling ring 311. By adjusting the tilt angle of the mounting plate 200, the forward rolling speed of the bearing outer ring is controlled, ensuring that only one bearing outer ring can pass over the lower positioning roller 310 during the contact time between the pitch-changing part 412 and the rolling ring 311. This allows the lower positioning roller 310 to release only the chamfered bearing outer ring during its downward and subsequent upward movement. When the lower positioning roller 310 moves upward, it drives the upper positioning roller 320 to move downward at the same amplitude via the rack 362 and gear 361. Conversely, the lower positioning roller 310 moves downward while the upper positioning roller 320 moves upward, achieving opposite movement between them. The contraction of the tension spring 350 causes the lower positioning roller 310 to press against the cam 410, facilitating its downward movement.

[0039] like Figures 4 to 10As shown, in this embodiment, the pushing component 600 further includes a fixed base 610, which is fixedly mounted on the mounting plate 200. A sliding base 620 is slidably connected to the fixed base 610. The extrusion roller 630 is rotatably mounted at one end of the sliding base 620. A second drive motor 640 is fixedly mounted on the sliding base 620. The output end of the second drive motor 640 is connected to the extrusion roller 630. A second cylinder 650 is fixedly mounted on the mounting plate 200. The output end of the second cylinder 650 is fixedly connected to the other end of the sliding base 620. The second cylinder 650 is used to drive the sliding base 620 to tilt and move.

[0040] In practice, the output end of cylinder 650 pushes the sliding seat 620 diagonally forward, causing the extrusion roller 630 to move diagonally forward, thus facilitating the insertion of the extrusion roller 630 into the outer ring of the bearing, thereby contacting and extruding with the inner ring of the outer ring of the bearing. The drive motor 640 drives the extrusion roller 630 to rotate, and the extrusion roller 630 drives the outer ring of the bearing to rotate. When the extrusion roller 630 is reset, it moves diagonally backward, so that the reset extrusion roller 630 avoids blocking the outer ring of the bearing, facilitating the forward rolling of the outer ring of the bearing. Example 2

[0041] Based on Embodiment 1, in order to facilitate the rolling of the bearing outer ring along the feeding channel 250, the width of the feeding channel 250 is larger than that of the bearing outer ring, resulting in the bearing outer ring having a margin for left and right movement. When it is inconvenient to grind, the bearing outer ring is centered relative to the two grinding wheels 730, resulting in a difference in the chamfering range on both sides. In order to compensate for the problem of the bearing outer ring being limited during grinding in Embodiment 1, so as to achieve the same chamfering effect on both sides of the bearing outer ring.

[0042] like Figures 4-7 As shown, in this embodiment, guide plate 210 is fixedly installed on mounting plate 200, guide plate 220 is slidably installed on mounting plate 200, cylinder 230 is fixedly installed at both ends of one side of mounting plate 200, the output end of cylinder 230 is fixedly connected to guide plate 220, upper baffle 211 is fixedly installed at one end of guide plate 210, two mounting shafts 720 are rotatably installed on span 700, two grinding wheels 730 are respectively installed at one end of the two mounting shafts 720, a dual-axis motor 710 is fixedly installed at the top of span 700, the output end of dual-axis motor 710 is rotatably connected to both mounting shafts 720, and a manual telescopic rod 110 is rotatably installed between the seat plate 100 and the other end of mounting plate 200, the length of manual telescopic rod 110 can be manually adjusted.

[0043] In specific implementation, cylinder 230 drives guide plate 220 to move laterally. When the lower positioning roller 310 moves down, cylinder 230 drives guide plate 220 to move away from guide plate 210, so that guide plate 220 releases the lateral pressure on multiple bearing outer rings, allowing the bearing outer rings to roll freely forward. Before the extrusion roller 630 contacts the bearing outer ring, cylinder 230 drives guide plate 220 to move towards guide plate 210, so that the bearing outer ring is close to guide plate 210. After the extrusion roller 630 contacts the bearing outer ring, the extrusion roller 630 will continue to move diagonally forward. The lateral movement of the extrusion roller 630 has the tendency to drive the bearing outer ring towards guide plate 210. Through the setting of the upper baffle 211, the upper part of the bearing outer ring is supported, preventing the bearing outer ring from tipping over under the lateral push of the extrusion roller 630.

[0044] In this invention, to facilitate operator control, a PLC controller can be set up, and drive motor 500, two cylinders 230, cylinder 650, drive motor 640 and dual-axis motor 710 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
