Description

Technical Field

[0001] The utility model relates to the technical field of bearing needle roller processing, in particular to a bearing needle roller rolling deburring device. Background Art

[0002] Bearing needle rollers are a special type of rolling element, which are slender cylinders with a small diameter and a large length ratio. These needle rollers roll freely in the bearing to reduce friction and wear between rotating parts, while supporting and transmitting radial and axial loads. Bearing needle rollers are usually made of high-carbon steel. Needles made of this material need to be finely machined and heat-treated to have high hardness and good wear resistance. At the same time, in order to ensure that the surface of the bearing needle rollers has a high finish and precision, they also need to be polished. For example, a bearing needle roller is disclosed in Chinese patent document CN209256528U. The invention relates to a workpiece end grinding and polishing device, comprising an operating table, a vertical threaded adjustment rod mounted on the operating table, the threaded adjustment rod being connected to a horizontal table via a threaded connection, the threaded adjustment rod being provided with an adjustment nut for fixing the table and adjusting the height of the table; a grinding device mounted at the front end of the table, a motor mounted at the rear end, the motor driving the grinding device, the grinding device comprising a pulley, a belt, and the motor, the pulley being connected to a driving pulley on the motor via the belt; a vertical grinding shaft mounted at the center of the pulley, and the grinding head being located below the table. The above patent is applicable to grinding and polishing roller ends and surfaces, but in actual production, when grinding a large number of bearing needle rollers, the circumferential grinding effect is better, while the end grinding effect is poor. The reason for this is that the diameter of the bearing needle rollers is too small, generally about 5 mm. Once the bearing needle rollers are misaligned, the ends of some bearing needle rollers will be concave, making it impossible for the grinding component to reach, thereby affecting processing efficiency and product quality.

[0003] Therefore, a bearing needle roller deburring device is provided. When the bearing needle roller is deburred, its end is ground specifically to prevent omissions, thereby improving processing efficiency and product quality, which is what technical personnel in this field need to do. Utility Model Content

[0004] The purpose of the utility model is to provide a bearing needle roller deburring device to solve the technical problem in the prior art that when a large number of bearing needle rollers are ground, the end grinding effect is poor and the grinding parts are easily out of reach, thereby affecting the processing efficiency and product quality.

The bearing needle roller rolling deburring device includes a base, and grinding tables are symmetrically provided on the base. Sliding tracks are provided on the opposite surfaces of the two grinding tables. The bearing needle roller is cooperatively connected in the two sliding tracks and can slide along the extension direction of the sliding tracks. Abrasives are installed in the wall of the grinding table, and one side of the abrasive extends into the sliding track and abuts against the end face of the bearing needle roller. A pushing head is slidably provided on the base, and the pushing head abuts the bearing needle roller, and the bearing needle roller can rotate in the pushing head.

[0006] Furthermore, the grinding table is provided with a loading port, which is opened downward from the plane of the grinding table and extends into the sliding track.

DETAILED DESCRIPTION

[0020] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0021] See also Figure 1 、 Figure 2 The utility model provides a bearing needle roller rolling deburring device for grinding and deburring the end of a bearing needle roller 20. The bearing needle roller rolling deburring device includes a base 10, on which grinding tables 11 are symmetrically provided. Sliding tracks 12 are provided on the opposite surfaces of the two grinding tables 11. The bearing needle roller 20 is connected in the two sliding tracks 12 and can slide along the extension direction of the sliding tracks 12. At the same time, an abrasive 13 is installed in the wall of the grinding table 11. One side of the abrasive 13 extends into the sliding track 12 and abuts against the end face of the bearing needle roller 20. A pushing head 14 is slidably provided on the base 10, and the pushing head 14 abuts against the bearing needle roller 20. The abrasive 13 includes but is not limited to block-shaped white corundum.

[0022] During use, the push head 14 is driven to move, thereby pushing the bearing needle roller 20 to roll in the sliding track 12 , and the abrasive 13 located in the sliding track 12 is used to grind and deburr the end of the bearing needle roller 20 .

[0023] Furthermore, the grinding table 11 is provided with a loading port 16, which extends downward from the upper surface of the grinding table 11 and extends into the sliding track 12. The bearing needle roller 20 is placed into the sliding track 12 through the loading port 16 to achieve loading. The grinding table 11 is provided with a discharge port 17 at one end away from the loading port 16. The discharge port 17 extends upward from the lower surface of the grinding table 11 and extends into the sliding track 12. The bearing needle roller 20 is discharged from the discharge port 17 to complete the discharge.

[0024] In this embodiment, a protrusion (not shown) is further provided on the grinding table 11 around the feeding port 16 to ensure the accuracy of feeding the bearing needle roller 20 and prevent the bearing needle roller 20 from being stuck.

[0025] In this embodiment, the distance between the two sliding rails 12 near the loading port 16 is greater than the distance between the two sliding rails 12 near the unloading port 17. As a result, when the bearing needle roller 20 is fitted and connected between the two sliding rails 12, it is easier to insert the sliding rail 12, thereby improving the convenience of installation. At the same time, as the distance between the two sliding rails 12 gradually decreases, the friction on the bearing needle roller 20 gradually increases, thereby improving the grinding effect on the end of the bearing needle roller 20 and ensuring processing stability.

[0026] In another embodiment, sandpaper is pasted on the inner wall of the sliding track 12 to reduce costs, facilitate adjustment of the distance and mesh size of the sandpaper, and improve the grinding effect on the end of the bearing needle roller 20.

[0027] In this embodiment, a cylinder 15 is provided on the base 10 , and the pushing head 14 is fixedly connected to a telescopic rod of the cylinder 15 . By starting the cylinder 15 , the pushing head 14 is driven.

[0028] See also Figure 3 、 Figure 4 、 Figure 5 The pushing head 14 has a C-shaped structure, and a pushing cavity 18 is formed on the inner wall of the pushing head 14. A pushing block 19 is provided in the pushing cavity 18. The cross section of the pushing block 19 is a right-angled trapezoid, and the inclined surface of the pushing block 19 faces the bearing needle roller 20. When in use, the pushing block 19 pushes the bearing needle roller 20 to slide in the sliding track 12, and the inclined surface of the pushing block 19 is used to make the bearing needle roller 20 rotate. Compared with the prior art, the bearing needle roller 20 remains stationary during grinding, and only one surface of its end is ground, which has the problem of uneven grinding. The utility model realizes comprehensive and complete grinding of the end of the bearing needle roller 20 by driving the bearing needle roller 20 to rotate and slide, and at the same time utilizes the relatively arranged sliding track 12 to enable the bearing needle roller 20 to slide along the fixed track and maintain a uniform arrangement to prevent leakage grinding.

[0029] In this embodiment, the pushing head 14 is provided with an arc surface 141 at one end close to the upper plane of the base 10, and the arc surface 141 is opposite to the bearing needle roller 20. The end of the pushing head 14 with the arc surface 141 is located below the bearing needle roller 20. In this way, when the pushing head 14 abuts against the bearing needle roller 20, the end with the arc surface 141 can ensure that the bearing needle roller 20 rolls smoothly into the pushing cavity 18, thereby ensuring the stability of the pushing and preventing it from falling off or changing the pushing position.

[0030] The pushing head 14 is provided with a limiting groove 142 in the pushing cavity 18. The limiting groove 142 is provided on the surface opposite to the arc surface 141. The limiting groove 142 is located above the bearing needle roller 20 and can abut the bearing needle roller 20. When in use, the bearing needle roller 20 abuts against the top wall of the sliding track 12 under the push of the inclined surface of the pushing block 19. When the bearing needle roller 20 is polished, the pushing head 14 retreats and resets, and the bearing needle roller 20 leaves the sliding track 12. At this time, the bearing needle roller 20 will move upward along the inclined surface of the pushing block 19 and then fall down under the action of inertia. If the pushing head 14 moves too slowly, the bearing needle roller 20 will be retained in the pushing cavity 18. If the pushing head 14 moves too fast, the shaft will be The bearing needle roller 20 is ejected from the pushing cavity 18 and cannot be accurately discharged from the discharge port 17. Therefore, in addition to controlling the moving speed of the pushing head 14, the utility model also uses the limit groove 142 to limit the movement of the bearing needle roller 20, so that the bearing needle roller 20 cannot be ejected from the pushing cavity 18. Under a stable moving speed, the bearing needle roller 20 will roll into the pushing cavity 18 along the arc surface 141, and finally roll out of the pushing cavity 18 through the arc surface 141 to complete the discharge.

[0031] In this embodiment, the telescopic rod of the cylinder 15 is fixedly connected to the side wall of the pushing head 14 by fasteners such as bolts or screws, so as to ensure the stability of the connection and facilitate debugging and maintenance.

[0032] The specific operation method of the present invention is as follows: Step 1: Place the bearing needle roller 20 into the sliding track 12 from the loading port 16 to achieve loading.

[0033] Step 2: Start the cylinder 15, and the push head 14 pushes the bearing needle roller 20 to move. The end of the bearing needle roller 20 is polished in the sliding track 12 to complete the polishing and deburring.

[0034] Step 3: The push head 14 moves to the discharge port 17, stops and resets, and the bearing needle roller 20 is discharged from the discharge port 17, completing the discharge.

[0035] The utility model arranges the end of the bearing needle roller 20 in the sliding track 12, and arranges an abrasive 13 in the sliding track 12 to achieve grinding and deburring of the end of the bearing needle roller 20. The sliding track 12 can achieve one-to-one grinding to ensure the grinding effect. At the same time, as the distance between the two sliding tracks 12 gradually decreases, the friction on the bearing needle roller 20 gradually increases, thereby improving the grinding effect of the end of the bearing needle roller 20 and ensuring processing stability. The utility model also achieves comprehensive and complete grinding of the end of the bearing needle roller 20 by driving the bearing needle roller 20 to rotate and slide, thereby preventing missed grinding.
