Description

Technical Field

[0001] This application relates to the field of roller bearing processing equipment technology, and in particular to a roller feeding device. Background Technology

[0002] Rollers are the load-bearing components of a bearing during operation. They are the weakest parts in a roller bearing, and their manufacturing quality has a significant impact on the bearing's performance (such as rotational accuracy, vibration, noise, and flexibility), and is a major factor affecting the bearing's service life.

[0003] The production process of rollers generally involves multiple steps. After each step is completed, the rollers are unloaded by a feeding device and then transported to other steps by a conveyor mechanism. Most current feeding devices use steel plate slides to unload the rollers, allowing them to slide down an inclined slide to a receiving platform. However, this method of directly dropping the rollers from the slide to the receiving platform has significant drawbacks. Due to the high speed of the rollers during the descent and the lack of an effective cushioning mechanism, the rollers are prone to violent collisions with the receiving platform, causing impact damage to the working surface of the rollers and affecting the quality and service life of the roller bearings. Utility Model Content

[0004] To address the problem that rollers are prone to damage during the feeding process, which affects the quality of roller bearings, this application provides a roller feeding device.

[0005] The roller feeding device provided in this application adopts the following technical solution: A roller feeding device includes a conveying mechanism, a feeding chute, and a receiving platform. The feeding chute is inclined. The device further includes: the end of the conveying mechanism is aligned with the upper end of the feeding chute; the receiving platform is located below the lower end of the feeding chute; a blocking mechanism is provided at the lower end of the feeding chute; the blocking mechanism extends into the feeding chute to prevent the roller from rolling directly onto the receiving platform; after the roller is blocked by the blocking mechanism, the blocking mechanism retracts from the feeding chute, allowing the roller to fall into the receiving platform.

[0006] By adopting the above technical solution, the end of the conveying mechanism is connected to the upper end of the unloading chute, and the receiving platform is located below the lower end of the unloading chute. A blocking mechanism is provided at the lower end of the unloading chute. Initially, the blocking mechanism extends into the unloading chute to prevent the rollers from rolling directly onto the receiving platform. After the rollers are stopped by the blocking mechanism, the blocking mechanism retracts from the unloading chute, allowing the rollers to fall onto the receiving platform. By setting up the blocking mechanism, the falling speed of the rollers can be effectively controlled, preventing the rollers from sliding directly onto the receiving platform at high speed, thereby avoiding impact damage to the roller surface.

[0007] Preferably, it also includes a base plate and a base, the base plate being fixed on the base, the material blocking mechanism including a stop block and a drive cylinder, the drive cylinder being fixed on the base plate, the stop block being fixed on the piston end of the drive cylinder, and the drive cylinder driving the stop block to extend into or retract from the material feeding chute.

The horizontal plate has an oblong hole. The second adjusting bolt slides and is fixed in the oblong hole on the horizontal plate to adjust the position of the drive cylinder.

[0011] Preferably, the base plate has arc-shaped adjustment ears extending from both sides, and the adjustment ears are provided with arc-shaped adjustment holes. A third adjustment bolt passes through the adjustment hole and is fixed to the base after sliding within the adjustment hole.

[0012] Preferably, the feeding chute is connected to an adjusting seat, which is fixed on the base. The adjusting seat is fixed at one end of the feeding chute near the conveying mechanism. The adjusting seat includes a first adjusting plate and a second adjusting plate. The first adjusting plate is fixed on the base, and the second adjusting plate can be adjusted vertically and then fixed on the first adjusting plate. Connecting ears extend from both sides of the feeding chute, and the second adjusting plate can be adjusted horizontally and then fixed on the connecting ears.

[0013] Preferably, the first adjusting plate has a waist-shaped hole in the vertical direction, the second adjusting plate has a waist-shaped hole in the horizontal direction, and fastening bolts are inserted into the waist-shaped holes of the first adjusting plate and the second adjusting plate.

[0014] Preferably, the material feeding chute is covered with a demagnetizer, which is fixed to the base plate.

[0015] Preferably, the end of the conveying mechanism is provided with an inductive switch.

[0016] In summary, this application includes at least one of the following beneficial technical effects: It can effectively control the falling speed of the roller and prevent the roller surface from being damaged by impact. The material blocking mechanism stops the roller during its sliding process, preventing the roller from sliding directly at high speed onto the receiving platform. The feeding process is highly automated, improving feeding accuracy and efficiency, and saving energy. By setting an induction switch, the roller is automatically sensed to indicate the start of the demagnetizer, and instructions are given to the material blocking mechanism. The feeding rhythm can be controlled by adjusting the material blocking mechanism and the inclination of the feeding slide. With a wide range of applications, it can be adapted to rollers of different specifications and weights. The position and inclination of the feeding slide and the position of the material blocking structure can all be adjusted. The demagnetizer can also be replaced with other processing and testing equipment to suit different processes. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a roller feeding device. (Refer to...) Figure 1 The roller feeding device includes a conveying mechanism 1, a feeding chute 2, a blocking mechanism 3, and a receiving platform 4. The feeding chute 2 is inclined, allowing the rollers to fall from a higher position to a lower position under gravity. The end of the conveying mechanism 1 is aligned with the upper end of the feeding chute 2, and the conveying mechanism 1 is used to transport the rollers onto the feeding chute 2. The receiving platform 4 is located below the lower end of the feeding chute 2, and the receiving platform 4 is used to receive the rollers that slide out of the feeding chute 2. The blocking mechanism 3 is located at the lower end of the feeding chute 2, and the blocking mechanism 3 is used to extend into the feeding chute 2 to prevent the rollers from rolling directly onto the receiving platform 4. The roller is conveyed by the conveying mechanism 1 to the inclined feeding slide 2. Under the action of gravity, the roller slides along the feeding slide 2. When the roller slides to the lower end of the feeding slide 2, the blocking mechanism 3 extends into the feeding slide 2 to prevent the roller from rolling directly to the receiving platform 4. After blocking the roller, the blocking mechanism 3 exits the feeding slide 2, so that the roller falls into the receiving platform 4 at a low speed and smoothly, thereby limiting the roller from being damaged by impact.

[0024] Reference Figure 2 The material blocking mechanism 3 includes a stop block 31 and a drive cylinder 32. The stop block 31 is connected to the piston end of the drive cylinder 32. The discharge slide 2 is provided with a base plate 5 and a base 6. The base plate 5 and the discharge slide 2 are fixed on the base 6, and the drive cylinder 32 is fixed on the base plate 5. The stop block 31 is used to hold the roller to prevent the roller from sliding out of the discharge slide 2. The material of the stop block 31 is selected to be wear-resistant to maintain a long service life. The drive cylinder 32 is used to drive the stop block 31 to extend into or retract from the discharge slide 2. The drive cylinder 32 can be a single-acting cylinder or a double-acting cylinder. This application uses a single-acting cylinder, and specifically a normally open single-acting cylinder, which has a simple structure and low cost. The drive cylinder 32 drives the stop block 31 to stop at the lower end of the discharge slide 2. When the roller is stopped by the stop block 31, the drive cylinder 32 closes, causing the stop block 31 to retract from the discharge slide 2 to release the roller.

[0025] Reference Figure 3 A connecting seat 321 is fixed to the drive cylinder 32, and a fixing post 51 is fixed to the base plate 5. The connecting seat 321 and the fixing post 51 are fixedly connected to fix the drive cylinder 32 to the base plate 5. The connection between the connecting seat 321 and the fixing post 51 is preferably bolted. A first adjusting bolt 322 is connected to the connecting seat 321, and the first adjusting bolt 322 passes through and is fixed to the fixing post 51 to fix the fixing post 51 and the connecting seat 321. To allow for flexible adjustment of the connecting seat 321, a slotted hole is provided on the fixing post 51 in a direction perpendicular to the base plate 5. When the height of the drive cylinder 32 needs to be adjusted, the first adjusting bolt 322 is slid along the slotted hole on the fixing post 51 to a suitable position and then tightened. The connecting seat 321 can adopt different structural forms, such as an integrally formed structure or a combined structure.

[0026] In a preferred embodiment, the connecting seat 321 includes a first connecting plate 323 and an L-shaped second connecting plate 324, which are fixedly connected. The second connecting plate 324 includes a horizontal plate 325 and a vertical plate 326 integrally connected. The vertical plate 326 is fixedly connected to the cylinder body of the drive cylinder 32, and the horizontal plate 325 is fixedly connected to the first connecting plate 323. The position of the drive cylinder 32 can be adjusted by adjusting the position of the horizontal plate 325. Similarly, a second adjusting bolt 327 is connected to the first connecting plate 323. The second adjusting bolt 327 passes through and is fixed to the first connecting plate 323. In order to enable flexible adjustment between the first connecting plate 323 and the second connecting plate 324, a waist-shaped hole is provided on the horizontal plate 325. The opening direction of the waist-shaped hole can be set according to actual needs. Since the drive cylinder 32 needs to be aligned with the feeding slide 2, it is generally not necessary to adjust the drive cylinder 32 along the width direction of the feeding slide 2 when the position of the feeding slide 2 is fixed. Therefore, the waist-shaped hole of the horizontal plate 325 is opened in a direction perpendicular to the vertical plate 326, so that the position of the drive cylinder 32 can be finely adjusted, further improving the flexibility and adaptability of the material blocking mechanism 3.

[0027] The base plate 5 has arc-shaped adjusting ears 52 extending from both sides. The adjusting ears 52 are fixed to the base plate 5. The adjusting ears 52 have arc-shaped adjusting holes 521. A third adjusting bolt 522 passes through the adjusting hole 521. The third adjusting bolt 522 can slide within the adjusting hole 521 and then be fixed to the base 6, thereby allowing the position of the base plate 5 to be adjusted. By adjusting the base plate 5, the angle and position of the feeding slide 2 on the base plate 5 can be adjusted, thereby controlling the sliding speed of the roller in the feeding slide 2, reducing surface damage of the roller in the feeding slide 2, and accommodating rollers of different specifications.

[0028] Reference Figure 4The feeding chute 2 is connected to an adjusting seat 7, which is used to fix the feeding chute 2 to the base 6. The feeding chute 2 is fixed to the adjusting seat 7, and the adjusting seat 7 is fixed to the base 6. The adjusting seat 7 is fixed at one end of the feeding chute 2 near the conveying mechanism 1. Specifically, the adjusting seat 7 includes a first adjusting plate 71 and a second adjusting plate 72, which are fixedly connected. The second adjusting plate 72 can be adjusted vertically and then fixed to the first adjusting plate 71, which is fixed to the base 6. The second adjusting plate 72 is fixedly connected to the feeding chute 2, and a connecting ear 21 extends from the side of the feeding chute 2. The second adjusting plate 72 can be adjusted horizontally and then fixed to the connecting ear 21. Similarly, in one specific implementation, the first adjusting plate 71 has a slotted hole in the vertical direction, and the second adjusting plate 72 has a slotted hole in the horizontal direction. Fastening bolts pass through the slotted holes of the first adjusting plate 71 and the second adjusting plate 72. The fastening bolts of the first adjusting plate 71 are used to fix the first adjusting plate 71 and the second adjusting plate 72 together, and the fastening bolts of the second adjusting plate 72 are used to fix the second adjusting plate 72 and the connecting lug 21 together. By adjusting the fastening bolts of the first adjusting plate 71, the material feeding chute 2 can be adjusted in the vertical direction, and by adjusting the fastening bolts of the second adjusting plate 72, the material feeding chute 2 can be adjusted in the horizontal direction.

[0029] Reference Figure 2 The unloading slide 2 is covered by a demagnetizer 8, which is fixed to the base plate 5. The function of the demagnetizer 8 is to eliminate any residual magnetism on the rollers as they pass through the unloading slide 2, thereby preventing the magnetism from affecting the rollers in subsequent processes or in their performance. Obviously, the demagnetizer 8 can also be replaced by other processing or quality inspection equipment. The roller unloading device of this application is suitable for unloading in different processes.

[0030] Reference Figure 1 An inductive switch is provided at the end of the conveying mechanism 1. After the roller passes the inductive switch, the inductive switch instructs the demagnetizer 8 to start, and the roller is demagnetized while sliding in the unloading slide 2. The inductive switch is also used to instruct the blocking mechanism 3. In this application, the blocking block 31 is always extended into the unloading slide 2 in the initial state. In this case, the blocking block 31 can be instructed to exit the unloading slide 2 by the inductive switch, or the blocking mechanism 3 can be controlled by its own program. When the roller abuts the blocking block 31, the blocking block 31 exits the unloading slide 2 to release the roller. In the case that the blocking block 31 is not extended into the unloading slide 2 in the initial state, the blocking block 31 can be controlled to extend into the unloading slide 2 by the inductive switch.

[0031] The receiving platform 4 is used to receive the rollers. The surface material of the receiving platform 4 is preferably a material with cushioning properties to further limit the rollers from slipping onto the receiving platform 4 and causing impact damage. A conveying device is also provided under the receiving platform 4 to transport the rollers that roll off the receiving platform 4. The inductive switch can also be set to detect a roller before instructing the conveying device to start; this on-demand method can reduce energy consumption to some extent.

[0032] The implementation principle of the roller feeding device in this application embodiment is as follows: When the roller passes the induction switch from the conveying mechanism 1, the induction switch instructs the demagnetizer 8 to start and prompts the blocking mechanism 3 that a roller will pass. The roller is conveyed from the conveying mechanism 1 into the feeding chute 2. Under the action of gravity, the roller rolls in the feeding chute 2. At the same time, the demagnetizer 8 performs demagnetization. At this time, the stop block 31 is in the feeding chute 2 to block the sliding roller. Then, the drive cylinder 32 drives the stop block 31 to exit the feeding chute 2, so that the roller falls smoothly and slowly to the receiving platform 4.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
