Description

Technical Field

[0001] The utility model relates to the technical field of bearing needle rollers, in particular to a feeding device for bearing needle rollers. Background Art

[0002] The needle roller is a component of the bearing, also known as a roller. The needle roller is usually cylindrical, made of a high-hardness metal material (such as steel) and has a smooth surface. The function of the needle roller is to transfer and share the load in the bearing. When the bearing is subjected to rotation or reciprocating motion, the needle roller rolls along the raceway between the inner and outer rings, thereby reducing rolling friction and sliding friction, while supporting and positioning the inner and outer rings of the bearing. The design purpose of the needle roller feeding device is to improve production efficiency, reduce manual intervention and improve product quality. It can be used in various industrial fields, such as automobile manufacturing, machinery manufacturing, electronic equipment manufacturing, etc. However, due to the small size of the needle roller and the thin and long cylindrical structure, the feeding of the needle roller is not only inefficient, but also the transmission structure is complex and easy to jam, which greatly affects the processing efficiency. Large-scale feeding cannot guarantee the processing effect, affecting the processing quality.

[0003] In order to solve the above technical problems, Chinese patent CN202296351 U discloses a slender shaft feeder, including a frame, a material holding inclined plate is provided on the upper part of the frame, a slideway is vertically provided inside one side of the frame, a feeding port is provided at the lower side of the material holding inclined plate, and the feeding port is connected to the slideway; a slide plate is provided in the slideway so as to slide up and down, and a conveyor belt is provided outside the side of the frame provided with the slideway, and the conveyor belt is arranged parallel to the slideway. The utility model uses a slide plate to eject the workpiece onto the conveyor belt to complete automatic feeding; however, the direct contact between the slide plate and the slideway has a large friction, which is easy to heat up and wear during use. At the same time, the transmission of the conveyor belt is not stable enough, and the workpiece is prone to deviation and falling off.

[0004] Therefore, it is necessary for technicians in this field to provide a feeding device for bearing needle rollers, reduce manual operations, adopt an automated and continuous feeding method, and improve production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0023] See also Figure 1 The utility model provides a feeding device for a bearing needle roller, which is used for feeding a needle roller 30. The feeding device includes a loading box 21 and a first feeding compression cylinder 28 installed on one side of the loading box 21. When working, the needle roller 30 is placed in the loading box 21, and the output end of the first feeding compression cylinder 28 is used to push the needle roller 30 to the outside of the loading box 21 and into the feeding port (not shown) to complete the feeding process.

[0024] For further information, see Figure 2 , Figure 4The charging box 21 is a box structure with an open top surface, and the bottom wall of the charging box 21 is inclined toward the direction of the first feeding compression cylinder 28. The needle roller 30 is placed in the charging box 21 from the opening surface of the charging box 21 and can roll along the inclined surface of the charging box 21.

[0025] The loading box 21 has a loading plate 25 detachably connected to the side thereof. The loading plate 25 has a V-shaped structure and a V-shaped groove is formed on the upper surface of the loading plate 25 . The loading plate 25 faces the first feeding compression cylinder 28 , and the output shaft of the first feeding compression cylinder 28 is slidably disposed in the V-shaped groove of the loading plate 25 .

[0026] A baffle 26 is detachably connected to the surface of the loading box 21 facing the loading plate 25, and a gap is left between the baffle 26 and the bottom wall of the loading box 21, and the needle rollers 30 cooperate with the gap. When in use, the gap can be used for the needle rollers 30 at the bottom layer of the loading box 21 to pass through. Except for the needle rollers 30 at the bottom layer, the remaining needle rollers 30 will be blocked by the baffle 26, thereby ensuring that the needle rollers 30 can pass through the gap in turn, preventing blockage and ensuring stability in use.

[0027] When in use, the needle roller 30 in the loading box 21 can be moved from the loading box 21 to the top of the loading plate 25, and then the first feeding compression cylinder 28 is used to push the needle roller 30 into the loading port to complete the loading.

[0028] It can be understood that the first feeding compression cylinder 28 is a pneumatic cylinder or a hydraulic cylinder, which is not limited here.

[0029] For further information, see Figure 3 , Figure 5 A limiting plate 251 is provided between the loading plate 25 and the baffle 26 , a guide plate 252 is connected between the top of the limiting plate 251 and the loading plate 25 , and a gap is formed between the side of the charging box 21 corresponding to the gap and the limiting plate 251 .

[0030] A sub-box 22 is provided below the loading box 21. A guide plate 27 is fixedly connected to the surface of the sub-box 22 facing the loading plate 25. A top plate 23 is slidably provided on the guide plate 27. The top plate 23 and the limit plate 251 are parallel to each other. The top plate 23 is arranged in the gap between the limit plate 251 and the loading box 21. The top of the top plate 23 can block the gap so that the needle roller 30 in the loading box 21 rolls out of the gap and slides into the top of the top plate 23. A second feeding compression cylinder 29 is fixedly connected below the sub-box 22. The top plate 23 is fixedly connected to the output shaft of the second feeding compression cylinder 29. When in use, the top plate 23 slides up and down along the guide plate 27 under the drive of the second feeding compression cylinder 29. It can be understood that the second feeding compression cylinder 29 is a cylinder or a hydraulic cylinder, which is not limited here.

[0031] The top plate 23 is slidably disposed between the loading box 21 and the first feeding compression cylinder 28, the top of the top plate 23 abuts against the needle roller 30, and the top of the top plate 23 is slidably disposed between the top surface of the loading plate 25 and the bottom wall of the loading box 21. When in use, when the top plate 23 moves downward along the guide plate 27, the top surface of the top plate 23 is flush with the bottom wall of the loading box 21, and the needle roller 30 in the loading box 21 moves to the top surface of the top plate 23; when the top plate 23 moves upward along the guide plate 27, the top plate 23 abuts against the needle roller 30 and moves together, thereby causing the needle roller 30 to move along the limit plate 251 to the upper surface of the guide plate 252 and then slide into the V-shaped groove of the loading plate 25, so as to move the needle roller 30 in the loading box 21 from the loading box 21 to the top of the loading plate 25, thereby completing the feeding operation of a single needle roller 30.

[0032] In this embodiment, a slider 231 is provided on the top plate 23, a track 271 is provided on the guide plate 27, and the slider 231 is connected to the track 271. The utility model uses the slider 231 and the track 271 to reduce the contact area between the top plate 23 and the guide plate 27, thereby preventing frictional heating or wear, thereby ensuring the stability of the movement of the top plate 23. Furthermore, a dovetail groove is provided on the slider 231, and a dovetail boss is provided on the track 271. The dovetail groove is connected to the dovetail boss, thereby ensuring the stability of the sliding connection.

[0033] In this embodiment, the bottom wall of the loading box 21 is inclined to ensure the continuity of feeding; the top surface of the top plate 23 is inclined, and the inclined surface is inclined toward the direction of the limit plate 251, so as to ensure that the needle roller 30 can stably roll down between the top plate 23 and the limit plate 251, thereby ensuring the stability during movement and improving the automation effect. In addition, the guide plate 252 is also inclined, and the guide plate 252 is inclined toward the direction of the carrier plate 25 and overlapped on the top surface of the carrier plate 25, so that the needle roller 30 can slide along the guide plate 252 to the carrier plate 25 when it is pushed to one end of the guide plate 252 by the top plate 23.

[0034] The specific operation method of the utility model is as follows: the needle roller 30 is placed in the loading box 21, the needle roller 30 automatically slides down and abuts against the limit plate 251, the second feeding compression cylinder 29 is started, and the top plate 23 moves upward along the guide plate 27 driven by the second feeding compression cylinder 29 and abuts against the needle roller 30, so that the needle roller 30 moves to the top surface of the limit plate 251 and slides from the guide plate 252 into the V-shaped structure of the loading plate 25, the first feeding compression cylinder 28 is started, and the output shaft of the first feeding compression cylinder 28 pushes the needle roller 30 and pushes it into the loading port to complete the loading process.

[0035] The utility model has high automation. The top plate 23 will move up and down along the guide plate 27 in a cycle under the drive of the second feeding compression cylinder 29, thereby realizing automatic feeding and effectively preventing material jamming. Only the needle roller 30 needs to be added to the loading box 21 manually to automatically complete the feeding and feeding process of a single workpiece, thereby reducing labor costs and improving production safety and production efficiency. At the same time, the utility model uses the slider 231 and the track 271 to cooperate to reduce the contact area between the top plate 23 and the guide plate 27, thereby preventing friction heating or wear, thereby ensuring the stability of the top plate 23 during movement.
