Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing production, in particular to a discharging mechanism of an inner circle grinding machine for bearings. Background Art
[0002] As a key equipment for precision machining, the design and technical core of an inner circle grinding machine for bearings lies in achieving highly precise grinding of the inner rings of bearings. These grinding machines usually incorporate advanced numerical control technology and precision measurement systems, which can accurately control the grinding depth, speed, and feed rate to ensure that each inner ring of the bearing can meet the required dimensional accuracy and surface quality standards. The spindle system of the grinding machine is specially designed to provide high rigidity and stability, and the selection and configuration of the grinding wheel are carefully matched according to the bearing material and the required processing characteristics to optimize the grinding effect.
[0003] To adapt to continuous production processes, inner circle grinding machines for bearings also integrate automated loading and unloading systems to improve production efficiency and reduce manual intervention. These systems include robotic arms, conveyor belts, and automatic positioning devices, which can quickly and accurately feed the inner rings of bearings into the grinding position and remove the finished products. However, with the continuous increase in the requirements for production efficiency, the limitations of traditional discharging mechanisms have gradually emerged. Especially when it is necessary to further improve the automation level, such as introducing a more efficient multi-station discharging system, the existing grinding machine structure may not be directly compatible.
[0004] This challenge mainly stems from the conflict between the physical space requirements of the discharging mechanism and the original structure of the grinding machine. For example, some design solutions may require channels to be opened on the protective cover of the grinding machine so that the discharging mechanism can smoothly remove the ground inner rings of bearings from the working area. Another situation is that the discharging mechanism may need to pass through the position of the spindle box, which not only involves modifying the structure of the spindle box but also requires considering how to avoid adverse effects on the spindle performance. Therefore, in order to integrate a more efficient and automated discharging system, it is often necessary to redesign the external structure of the inner circle grinding machine for bearings. Summary of the Utility Model
[0005] Aiming at the deficiencies in the prior art, the utility model provides a discharging mechanism of an inner circle grinding machine for bearings, which solves the technical problem that the setting of the existing discharging mechanism usually requires changing the overall structure of the inner circle grinding machine for bearings and cannot be directly installed.
[0006] According to an embodiment of the utility model, a discharging mechanism of an inner circle grinding machine for bearings is provided. The inner circle grinding machine for bearings includes a bed body, a spindle box arranged on one side of the bed body, and a tailstock arranged on the other side of the bed body. A grinding head is arranged on the telescopic rod of the tailstock, a chuck is arranged on the spindle box, the center of the chuck is aligned with the center of the grinding head, an electric slide rail is arranged on the upper side of the bed body, the tailstock is installed on the electric slide rail, and a grasping device is arranged on the tailstock;
[0007] The discharging mechanism includes an inclined track and a conveying device. The conveying device is arranged on one side of the bed body close to the tailstock. The inclined track is installed on the lower side of the tailstock. The inclined track inclines towards the conveying device. One end of the inclined track is aligned with the conveying device, and the other end of the inclined track is aligned with the grasping device.
[0008] The technical principle of the present utility model is as follows: A grasping device is directly installed on the tailstock to grasp the inner ring of the bearing that has been processed on the chuck, and then it falls onto the inclined track. The inner ring of the bearing slides down along the inclined track onto the conveying device and is finally conveyed away. Since the inclined track is directly installed on the lower side of the tailstock, and the bed body part itself is a hollow structure for storing waste. Also, since the waste of the internal grinder for bearing inner circles is all metal powder and will occupy too much internal space of the bed body, installing the inclined track here will not cause a change in the structure of the internal grinder for bearing inner circles.
[0009] Compared with the prior art, the present utility model has the following beneficial effects: By means of the grasping device arranged on the tailstock cooperating with the discharging mechanism arranged under the tailstock, it solves the technical problem that the existing discharging mechanism usually needs to change the overall structure of the internal grinder for bearing inner circles and cannot be directly installed.
[0010] Further, the grasping device includes an annular cover, an electric push rod, and a grasping part. The annular cover is movably installed on the tailstock. The annular cover covers the grinding head. The electric push rods are circumferentially and evenly distributed inside the annular cover. The grasping part is installed on the piston rod of the electric push rod.
[0011] Further, the annular cover is in a frustum shape, and the large end face of the annular cover faces the tailstock. The edge of the large end face of the annular cover is aligned with the inclined track.
[0012] Further, the inclination of the inclined track is less than or equal to the inclination of the cylindrical surface of the annular cover.
[0013] Further, the inclination of the inclined track is 5 - 8°.
[0014] Further, the cross-section of the inclined track at the end close to the annular cover is in a circular arc structure, and the cross-section of the inclined track at the end close to the conveying device is in a rectangular groove structure. The inclined track gradually changes from one end with a circular arc structure to one end with a rectangular groove structure.
[0015] Further, the conveying device includes a conveying frame and a conveyor belt mechanism installed on the conveying frame. A cross bar is provided at one end of the conveying frame close to the tailstock, and a baffle is hinged on the cross bar.
[0016] Further, there is a gap between the cross bar and the upper surface of the conveyor belt mechanism. Description of the Drawings

Detailed implementation manners
[0028] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.
[0029] Embodiment 1
[0030] As Figure 1The shown internal grinding machine for bearing inner rings includes a machine body 100, a headstock 110 arranged on one side of the machine body 100, and a tailstock 120 arranged on the other side of the machine body 100. A grinding head 121 is provided on the telescopic rod of the tailstock 120 for grinding the bearing inner ring. A chuck 130 is provided on the headstock 110 for clamping the bearing inner ring. The center of the chuck 130 is aligned with the center of the grinding head 121. An electric slide rail 101 is provided on the upper side of the machine body 100, and the tailstock 120 is installed on the electric slide rail 101. Furthermore, the electric slide rail 101 can drive the tailstock 120 to move closer to and away from the chuck 130.
[0031] As Figure 1-2 shown, a grasping device is provided on the tailstock 120. Specifically, the grasping device includes an annular cover 200, an electric push rod 210, and a grasping part 220. Among them, the annular cover 200 is of a mesh structure. The annular cover 200 is installed on the tailstock 120, and the annular cover 200 covers the grinding head 121 to play a protective role. The electric push rods 210 are circumferentially and evenly distributed inside the annular cover 200. The grasping part 220 is installed on the piston rod of the electric push rod 210, so that the grasping part 220 can clamp the bearing inner ring.
[0032] Embodiment 2
[0033] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that: the grasping part 220 is of an L-shaped structure. The bottom of the grasping part 220 is a grasping end 221 for clamping on the outer surface of the bearing inner ring. A convex tooth 222 is provided on one side of the grasping part 220 close to the chuck 130. An elastic rod 223 is connected between the grasping part 220 and the convex tooth 222. An annular tooth 131 is provided at the outer edge of the chuck 130, and the annular tooth 131 cooperates with the convex tooth 222.
[0034] As Figure 4-5 shown, an arc-shaped track 230 is provided between the top of the end face of the annular cover 200 and the tailstock 120. The outer edge of the annular cover 200 is clamped into the arc-shaped track 230. Among them, rollers 231 are evenly distributed between the arc-shaped track 230 and the outer edge of the annular cover 200, and rollers 231 are also evenly distributed between the arc-shaped track 230 and the inner wall and outer wall of the annular cover 200.
[0035] As Figure 4 、 6 shown, an annular track 240 is provided on one side of the headstock 110 close to the chuck 130. The annular track 240 is aligned with the outer edge of the annular cover 200. The outer edge of the annular cover 200 is clamped into the annular card slot. Specifically, rollers 231 are evenly distributed on the annular track 240, and the balls are closely attached to the outer edge of the annular cover 200.
[0036] In this embodiment, when processing the bearing inner ring, the grasping end 221 is clamped on the bearing inner ring. Therefore, the annular cover 200 needs to rotate synchronously with the chuck 130.
[0037] Example 3
[0038] As Figure 7 shown, the difference between this embodiment and Embodiments 1-2 is that: a discharging device is provided on the internal grinding machine for bearings. The discharging mechanism includes an inclined track 300 and a conveying device 400. The conveying device 400 is arranged on one side of the bed body 100 close to the tailstock 120. The inclined track 300 is installed on the lower side of the tailstock 120. The inclined track 300 inclines towards the conveying device 400. One end of the inclined track 300 is aligned with the conveying device 400, and the other end of the inclined track 300 is aligned with the grasping device, ensuring that the inclined track 300 can receive the inner ring of the bearing dropped on the grasping device and convey it onto the conveying device 400.
[0039] As Figure 7 shown, the annular cover 200 has a frustum-shaped structure, and the large end face of the annular cover 200 faces the tailstock 120. The edge of the large end face of the annular cover 200 is aligned with the inclined track 300, forming an inclination angle to facilitate the inner ring of the bearing to slide onto the inclined track 300. In order to ensure smooth sliding and avoid too fast sliding speed, the inclination angle of the inclined track 300 is 5-8°, and the inclination angle of the inclined track 300 is less than or equal to the inclination angle of the cylindrical surface of the annular cover 200. At the same time, in order to prevent the bearing from being scratched during the falling and sliding process, the annular cover 200 and the inclined track 300 are made of resin or hard rubber materials, etc., materials with high strength but low hardness.
[0040] As Figure 8-9 shown, the cross-section of the inclined track 300 near the annular cover 200 is an arc-shaped structure, and the cross-section of the inclined track 300 near the conveying device 400 is a rectangular groove structure. The inclined track 300 gradually changes from one end with an arc-shaped structure to one end with a rectangular groove structure, so that when the inner ring of the bearing slides in the inclined track 300, the left and right movement amounts gradually decrease, and finally it is accurately discharged onto the conveying device 400.
[0041] As Figure 7 、 10 shown, the conveying device 400 includes a conveying frame 410 and a conveyor belt mechanism 420 installed on the conveying frame 410. A cross bar 411 is provided at one end of the conveying frame 410 close to the tailstock 120. A baffle 412 is hinged on the cross bar 411. There is a gap between the cross bar 411 and the upper surface of the conveyor belt mechanism 420, so that the baffle 412 can hang down naturally, and the lying inner ring of the bearing can push open the baffle 412 and pass through the gap.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
