Description

Technical Field

[0001] This invention relates to the field of bearing assembly equipment technology, specifically a workbench for assembling rolling bearings. Background Technology

[0002] As a core component in mechanical transmission systems, the assembly precision of rolling bearings directly determines the operational stability, transmission efficiency, and service life of the equipment. In industrial production, the assembly of rolling bearings requires the completion of key processes such as outer ring fixing, inner ring positioning, precise filling of rolling elements, and cage assembly, which places stringent requirements on the clamping stability, positioning accuracy, material cutting accuracy, and ease of operation of the worktable.

[0003] However, most current rolling bearing assembly workbenches use a single manual clamping method, which is not only labor-intensive but also lacks precise positioning benchmarks and scale indications. This leads to easy misalignment and loosening of the bearing outer ring during fixing, affecting assembly efficiency. Simultaneously, the inner ring positioning method is crude; traditional workbenches often rely on manual hand positioning or simple pin positioning, failing to achieve smooth lifting and horizontal fine-tuning of the inner ring. This makes it difficult to accurately control the assembly gap between the inner and outer rings, resulting in uneven distribution of rolling elements during filling, and even jamming, severely impacting bearing performance. When assembling rolling elements, existing equipment often uses manual sorting and counting before placement, which is not only time-consuming and labor-intensive but also prone to human error leading to discrepancies in the number of rolling elements. The equipment has poor adaptability; when facing the assembly needs of bearings of different specifications and models, the replacement process for key components such as positioning blocks and clamping blocks is cumbersome, requiring tools for disassembly and installation, which is complex and time-consuming, severely restricting the flexibility of multi-variety, small-batch production. Furthermore, the assembled bearings are often tightly fitted to the workbench surface, requiring manual peeling, which is not only inconvenient but also easily causes scratches and bumps on the bearing surface, affecting product appearance and precision.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the rolling bearing assembly workbench of the present invention includes a workbench body 1 and a positioning component 3 disposed on the workbench body 1.

[0035] The positioning component 3 includes connecting strips 301 and fixing plates 302. Four connecting strips 301 are fixedly connected to the bottom of the workbench body 1. Fixing plates 302 are fixedly connected to the bottom of the four connecting strips 301. Connecting posts 303 are slidably connected to the fixing plates 302. A pedal 304 is fixedly connected to the bottom of the connecting posts 303. A lifting plate 305 is fixedly connected to the top of the connecting posts 303. Two slide rails 308 are fixedly connected to the lifting plate 305. Two sliding sleeves 309 are fixedly connected to each slide rail 308. A sliding plate 310 is fixedly connected to the four sliding sleeves 309. A fixed plate 310 is fixedly connected to the sliding plate 310. A mounting base 311 is provided, and a positioning block 312 is mounted on the mounting base 311 via a mounting component 5. A through groove 313 is provided on the worktable body 1, and the positioning block 312 is slidably connected to the through groove 313. A fixing strip 314 is fixedly connected to the lifting plate 305, and a second operating lever 315 is fixedly connected to the slide plate 310. The second operating lever 315 is slidably connected to the fixing strip 314. An ejection component 4 is provided on the fixing plate 302. Four guide columns 306 with a cross-section of "+" are fixedly connected to the lifting plate 305, and a third spring 307 is fixedly connected between the guide columns 306 and the fixing plate 302.

[0036] The ejector assembly 4 includes a fixed base 401 and a gear 402. The fixed base 401 is fixedly connected to the fixed plate 302, and the gear 402 is rotatably connected to the fixed base 401. A first rack 403 is fixedly connected to the lifting plate 305, and the first rack 403 meshes with the gear 402. Four lifting bars 405 are slidably connected to the worktable body 1. Two connecting shafts 404 are fixedly connected to the bottom end of each lifting bar 405. A lifting frame 406 is fixedly connected to the bottom end of the eight connecting shafts 404. A second rack 407 is fixedly connected to the lifting frame 406, and the second rack 407 meshes with the gear 402. A mounting block 40 is fixedly connected to the connecting shaft 404. 8. A fourth spring 409 is fixedly connected between the mounting block 408 and the worktable body 1. The inner ring of the bearing is positioned by the positioning component 3. In the initial state of the positioning component 3, the pedal 304 is in the depressed position, the lifting plate 305 is in the low position, and the positioning block 312 is fully retracted under the through groove 313 of the worktable body 1. After the pedal 304 is released, under the restoring force of the third spring 307 on the four guide columns 306, the lifting plate 305 rises smoothly, driving the mounting base 311 and the positioning block 312 through the through groove 313 and into the inner hole of the bearing inner ring. Then the operator pushes the second operating lever 315 forward, driving the slide plate 310 through the four sliding sleeves. 309 slides horizontally along the two slide rails 308, thereby pushing the positioning block 312 and the inner ring of the bearing to precisely approach the outer ring of the bearing that has been fixed by the clamping assembly 2, forming a uniform assembly gap. After the rolling element is inserted into the gap through the unloading assembly 6, the second operating lever 315 is pulled back to pull the inner ring of the bearing back into place. Finally, the pedal 304 is pressed down, overcoming the elastic force of the third spring 307 to lower the lifting plate 305, which drives the positioning block 312 to smoothly exit from the inner hole of the bearing inner ring to below the through groove 313. The first rack 403 installed on the lifting plate 305 moves down accordingly, driving the gear 402, which is rotatably connected to the fixed seat 401, to rotate counterclockwise. The gear 402 drives the gear 402 to rotate counterclockwise. The second rack 407 moves upward and is fixedly connected to the lifting frame 406, causing the lifting frame 406 to move upward synchronously. The lifting frame 406 drives the four lifting bars 405 to move upward through the eight connecting shafts 404, smoothly pushing the assembled bearing out of the worktable surface, making it easier for the operator to pick up the part. At the same time, the mounting block 408 on the connecting shaft 404 compresses the fourth spring 409 to complete the spring energy storage. When the pedal 304 is released, under the restoring force of the fourth spring 409, the mounting block 408 pushes the connecting shaft 404 and the lifting bars 405 downward to reset and retract into the worktable body 1, making room for bearing assembly.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 9 and Figure 10As shown, the workbench body 1 is provided with a clamping assembly 2, which includes a first fixing block 201 and a screw 202. The first fixing block 201 is fixedly connected to the workbench body 1, and the screw 202 is threadedly connected to the first fixing block 201. The end of the screw 202 is rotatably connected to a first clamping block 203. A handwheel 204 is fixedly connected to the end of the screw 202 away from the first clamping block 203. A guide rod 205 is fixedly connected to the first clamping block 203 and is slidably connected to the first fixing block 201. A second fixing block 208 is fixedly connected to the workbench body 1, and a first operating rod 209 is slidably connected to the second fixing block 208. The end of the first operating rod 209 is fixedly connected to a second clamping block 210. Two guide shafts 211 are fixedly connected to the second clamping block 210 and are slidably connected to the second fixing block 208. A first spring 212 is fixedly connected between the second clamping block 210 and the second fixing block 208.

[0038] A scale 207 is fixedly connected to the first clamping block 203, and a scale block 206 is fixedly connected to the first fixing block 201. The scale 207 and the scale block 206 are used in conjunction. A first slide bar 213 is slidably connected inside the second fixing block 208. A trapezoidal limit block 214 is fixedly connected to the first slide bar 213. A limit groove 215 is provided on the first operating rod 209. The limit block 214 engages with the limit groove 215. Two cross-shaped connecting rods are fixedly connected to the first slide bar 213. 216. Connecting rod 216 is slidably connected to second fixed block 208. Second spring 217 is fixedly connected between connecting rod 216 and second fixed block 208. Pressing block 218 is fixedly connected to the top of the two connecting rods 216. Rotating handwheel 204 drives screw 202 to rotate, causing first clamping block 203 to move linearly along guide rod 205, so that it fits against one side of the bearing outer ring as a fixed reference. At this time, observe the scale 207 on first clamping block 203 and the scale 2 on first fixed block 201. The scale between 0 and 6 precisely controls the initial position. Then, the operator presses the pressing block 218. The pressing block 218, via the connecting rod 216, causes the first slide bar 213 to move downwards against the elastic force of the second spring 217, disengaging the limiting block 214 on the first slide bar 213 from the limiting groove 215 on the first operating rod 209. At this point, under the elastic force of the first spring 212, the second clamping block 210, guided by the guide shaft 211, automatically slides towards the first clamping block 203 until it clamps the bearing. On the other side of the circle, the automatic clamping action is completed. When it is necessary to release the clamp, the operator pulls the first operating lever 209 outward, which drives the second clamping block 210 to move away from the first clamping block 203 against the pull of the first spring 212. When it moves to the appropriate position, the pressing block 218 is released, and the limiting block 214 is re-engaged into the limiting groove 215 under the action of the second spring 217, locking the first operating lever 209 in the current position and keeping the second clamping block 210 in the released state, which is convenient for removing or inserting the bearing.

[0039] Specifically, such as Figure 5 , Figure 7 and Figure 8 As shown, the mounting assembly 5 includes a mounting groove 501 and a base 502. The mounting base 311 has the mounting groove 501. The bottom end of the positioning block 312 is fixedly connected to the base 502, and the base 502 is inserted into the mounting groove 501. Two second slide bars 503 are slidably connected inside the mounting base 311. A fixing rod 504 is fixedly connected inside the mounting base 311. A fifth spring 505 is sleeved on the outside of the fixing rod 504. Both ends of the fifth spring 505 are fixedly connected to the two second slide bars 503 respectively. A pressing strip 506 is fixedly connected to the second slide bar 503, and the pressing strip 506 is slidably connected to the mounting base 311. A locking block 507 is fixedly connected to the second slide bar 503. The base 502 has a locking groove 508, and the locking block 507 engages with the locking groove 508. When it is necessary to replace the positioning block 312 with a different specification, the operator... The pressing strips 506 on both sides of the mounting base 311 can be pressed inward simultaneously. The pressing strips 506 drive the second slide strips 503 connected to them to slide inward along the fixing rod 504 against the elastic force of the fifth spring 505. This causes the locking block 507 fixed on the second slide strip 503 to disengage from the slot 508 on the side wall of the base 502 of the positioning block 312. At this time, the locking between the positioning block 312 and the base 502 and the mounting base 311 is released, and it can be taken directly upward from the mounting groove 501. During installation, align the base 502 at the bottom of the new positioning block 312 with the mounting groove 501 and insert it. Release the pressing strips 506. Under the restoring force of the fifth spring 505, the second slide strips 503 on both sides slide in opposite directions, causing the locking block 507 to automatically lock into the slot 508 on the base 502, thus completing the quick locking installation of the positioning block 312.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 11As shown, the workbench body 1 is equipped with a feeding assembly 6, which includes a support frame 601 and a distributing cylinder 602. The support frame 601 is fixedly connected to the workbench body 1, and the distributing cylinder 602 is installed on the support frame 601. The distributing cylinder 602 has eight storage channels 609 arranged in a circular array inside. An upper distributing plate 606 and a lower distributing plate 607 are rotatably connected inside the distributing cylinder 602. The upper distributing plate 606 and the lower distributing plate 607 are respectively located at both ends of the storage channels 609. Each of the upper distributing plate 606 and the lower distributing plate 607 has a distributing hole 608. The upper distributing plate 606 has a distributing hole 608. The material hole 608 is offset from the material distribution hole 608 on the lower material distribution plate 607. A mounting frame 604 is fixedly connected to the support frame 601, and a motor 610 is fixedly connected to the mounting frame 604. A connecting shaft 605 is rotatably connected to the material distribution cylinder 602, and the connecting shaft 605 is fixedly connected to the upper material distribution plate 606 and the lower material distribution plate 607. A discharge hopper 603 is fixedly connected to the top of the material distribution cylinder 602. Multiple stirring rods 611 are fixedly connected to the portion of the connecting shaft 605 located at the discharge hopper 603. A discharge hose 613 is fixedly connected to the bottom of the material distribution cylinder 602. A cross-section of [missing information] is fixedly connected to the support frame 601. The L-shaped hanging rod 612 has a feeding head 614 fixedly connected to the end of the feeding hose 613. The feeding head 614 is fastened to the hanging rod 612. Before operation, a sufficient amount of rolling elements is poured into the feeding hopper 603. The motor 610 is started to drive the connecting shaft 605, which drives the upper distributing plate 606 and the lower distributing plate 607 to rotate synchronously in the distributing cylinder 602. At the same time, the stirring rod 611 continuously stirs to prevent blockage. The eight storage channels 609 in the distributing cylinder 602 are fixed. Each channel can store all the rolling elements required to assemble a bearing. When the distributing hole 608 of the rotating upper distributing plate 606 passes through a certain storage channel, the rolling elements will rotate. When the ball is above channel 609, the channel is filled with a fixed amount of balls. Then, when the distribution hole 608 of the lower distribution plate 607 rotates to the bottom of the channel, all the balls required for one bearing stored in the channel fall down and are transported to the discharge head 614 through the discharge hose 613. During operation, the discharge head 614 can be hooked onto the L-shaped hanging rod 612. At this time, the discharge hose 613 is in a natural hanging state. Its internal length and volume are just enough to temporarily store the amount of balls required for one bearing, forming a buffer storage section. This not only facilitates the operator's hands to perform other assembly actions, but also ensures that the pre-measured single-use amount can be obtained directly when it is used again.

[0041] In use, the present invention firstly rotates the handwheel 204 to drive the screw 202 to rotate, causing the first clamping block 203 to move linearly along the guide rod 205, so that it fits against the outer ring of the bearing as a fixed reference. At this time, the scale between the scale 207 on the first clamping block 203 and the scale 206 on the first fixing block 201 can be observed to precisely control the initial position. Subsequently, the operator presses the pressing block 218, and the pressing block 218 drives the first slide bar 213 to move downward against the elastic force of the second spring 217 through the connecting rod 216, so that the limiting block 214 on the first slide bar 213 disengages from the limiting groove 215 on the first operating rod 209. At this time, the first spring 214... Under the elastic force of 12, the second clamping block 210 automatically slides towards the first clamping block 203 through the guide shaft 211 until it clamps the other side of the outer ring of the bearing, completing the automatic clamping action. When it is necessary to release the clamping, the operator pulls the first operating rod 209 outward, which drives the second clamping block 210 to move away from the first clamping block 203 against the tension of the first spring 212. When it moves to the appropriate position, the pressing block 218 is released, and the limiting block 214 is re-engaged into the limiting groove 215 under the action of the second spring 217, locking the first operating rod 209 in the current position and keeping the second clamping block 210 in the released state, which is convenient for taking out or putting in the bearing.

[0042] Then, the bearing inner ring is positioned by the positioning component 3. In the initial state of the positioning component 3, the pedal 304 is in the depressed position, the lifting plate 305 is in the low position, and the positioning block 312 is fully retracted below the through groove 313 of the worktable body 1. After the pedal 304 is released, under the restoring force of the third spring 307 on the four guide columns 306, the lifting plate 305 rises smoothly, driving the mounting base 311 and the positioning block 312 through the through groove 313 and into the inner hole of the bearing inner ring. Then, the operator pushes the second operating lever 315 forward, driving the slide plate 310 to slide horizontally along the two slide rails 308 through the four sliding sleeves 309, thereby pushing the positioning block 312 and the bearing inner ring to precisely approach the bearing outer ring that has been fixed by the clamping component 2, forming a uniform assembly gap. After the rolling element is inserted into the gap by the unloading component 6, the second operating lever 315 is pulled back to pull the bearing inner ring back into position. Finally, the pedal 304 is depressed to overcome the elastic force of the third spring 307. The lifting plate 305 is lowered, causing the positioning block 312 to smoothly exit from the inner hole of the bearing inner ring to below the through groove 313. The first rack 403 installed on the lifting plate 305 moves down accordingly, driving the gear 402, which is rotatably connected to the fixed seat 401, to rotate counterclockwise. The gear 402 drives the second rack 407, which meshes with it, to move upward. The second rack 407 is fixedly connected to the lifting frame 406, causing the lifting frame 406 to move upward synchronously. The lifting frame 406 drives the four lifting bars 405 to move upward through eight connecting shafts 404, smoothly pushing the assembled bearing out of the worktable surface, making it easy for the operator to pick up the part. At the same time, the mounting block 408 on the connecting shaft 404 compresses the fourth spring 409 to complete the spring energy storage. When the pedal 304 is released, under the restoring force of the fourth spring 409, the mounting block 408 pushes the connecting shaft 404 and the lifting bars 405 downward to retract into the worktable body 1, making room for bearing assembly.

[0043] Secondly, before operation, pour a sufficient amount of rolling balls into the hopper 603, start the motor 610 to drive the connecting shaft 605, causing the upper distribution plate 606 and the lower distribution plate 607 to rotate synchronously in the distribution cylinder 602. At the same time, the stirring rod 611 continuously stirs to prevent blockage. The eight storage channels 609 in the distribution cylinder 602 are fixed, and each channel can store all the rolling balls required to assemble one bearing. When the distribution hole 608 of the rotating upper distribution plate 606 passes over a certain storage channel 609, that channel is filled with a fixed amount of rolling balls, and then... When the distribution hole 608 of the lower distribution plate 607 rotates to the bottom of the channel, all the balls required for a bearing stored in the channel fall down and are transported to the discharge head 614 through the discharge hose 613. During operation, the discharge head 614 can be hooked onto the L-shaped hanging rod 612. At this time, the discharge hose 613 is in a natural hanging state, and its internal length and volume are just enough to temporarily store the amount of balls required for a bearing, forming a buffer storage section. This not only makes it convenient for the operator to perform other assembly actions with both hands, but also ensures that the measured single amount can be obtained directly when it is used again.

[0044] Finally, when it is necessary to replace the positioning block 312 with a different specification, the operator can simultaneously press the pressing strips 506 on both sides of the mounting base 311 inward. The pressing strips 506 drive the second slide strips 503 connected to them to slide inward along the fixing rod 504 against the elastic force of the fifth spring 505, so that the locking block 507 fixed on the second slide strip 503 disengages from the slot 508 on the side wall of the base 502 of the positioning block 312. At this time, the locking between the positioning block 312 and the base 502 and the mounting base 311 is released, and it can be taken directly upward from the mounting slot 501. During installation, align the base 502 at the bottom of the new positioning block 312 with the mounting slot 501 and insert it. Release the pressing strips 506. Under the restoring force of the fifth spring 505, the second slide strips 503 on both sides slide in opposite directions, causing the locking block 507 to automatically lock into the slot 508 on the base 502, thus completing the quick locking installation of the positioning block 312.

[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.
