Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and particularly relates to a grease injection and gland pressing device for bearing processing. Background Art

[0002] In the field of bearing manufacturing, grease injection and gland pressing, as key post - processing operations, directly affect the sealing performance and service life of bearings. In current industrial production, a split - type operation mode is generally adopted, that is, the grease injection process and the gland pressing process are completed at independent workstations respectively. This will lead to multiple clampings, increasing time costs and labor costs. At the same time, separate operations may affect the accuracy. For example, deviations may occur in two positionings, affecting product quality. In addition, the equipment occupies a large area and has high maintenance costs, which are all the disadvantages of the existing technology.

[0003] In addition to the problems of low efficiency in process connection and insufficient equipment coordination, the step - by - step operation also has the risk of grease contamination. The step - by - step operation is likely to cause grease oxidation or foreign matter intrusion during the open waiting stage (average 120 - 180s) after grease injection. According to industry data statistics, the proportion of early bearing failures caused by such problems reaches 12.7%.

[0004] At the same time, there are some devices in the prior art that attempt to integrate, but they have problems of complex structure and insufficient reliability.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0035] Embodiment 1

[0036] Refer to Figure 1 and Figure 7As shown in the figure, this is the first embodiment of the present invention, which provides a grease injection gland device for bearing processing, including a working component 10 and a main body component 30. The working component 10 includes a working frame 11 and a position-changing power component 12 installed on the working frame 11. A position-changing moving component 13 is connected to the position-changing power component 12, enabling the position-changing moving component 13 to move on the working frame 11. One end of the position-changing moving component 13 is equipped with a gland component 14, and the other end is equipped with a grease injection component 15. The main body component 30 includes a workbench 31 and a bearing placement table 32 installed on the workbench 31. A gland placement table 33 is arranged on one side of the bearing placement table 32, and a vertical plate 34 is connected to the workbench 31.

[0037] Among them, the working frame 11 is fixed on one side of the vertical plate 34. The position-changing power component 12 is installed on the working frame 11 and performs limited movement on the working frame 11. The position-changing moving component 13 is connected to the position-changing power component 12 in a rotating manner. At the same time, the position-changing moving component 13 performs limited movement on the working frame 11. The gland component 14 and the grease injection component 15 are respectively installed at both ends of the position-changing moving component 13. The movement of the position-changing moving component 13 can drive the gland component 14 and the grease injection component 15 to change positions.

[0038] The bearing placement table 32 and the gland placement table 33 are installed on the lower side of the working frame 11. A limiting cylinder is provided at the center of the bearing placement table 32, and an arc-shaped baffle is provided on the outside, where the bearing can be placed in it for preliminary limiting to prevent it from moving randomly. The gland can be placed inside the gland placement table 33. The movement of the gland component 14 can suck the gland and install the gland.

[0039] The position-changing power component 12 includes a first hydraulic cylinder 121 and a first push rod 122 connected to one end of the first hydraulic cylinder 121. Both ends of the first push rod 122 are connected with first racks 123. One side of the first racks 123 is connected with a first driven gear 124, and a rotating cam 125 is fixedly connected to the first driven gear 124.

[0040] There are two positions where the first racks 123 are arranged at one end of the first push rod 122, and they are symmetrically arranged about the center line of the first push rod 122. A limiting ring is arranged on the working frame 11, and the first racks 123 are installed in the limiting ring, enabling the first racks 123 to move in the limiting ring. The first driven gear 124 is rotatably installed inside the working frame 11, and the rotating cam 125 is fixedly connected to the first driven gear 124. The first racks 123 and the first driven gear 124 are connected in a meshing manner. The first racks 123 drive the first driven gear 124 to rotate, thereby enabling the rotating cam 125 to perform limited rotation.

[0041] The transposition moving part 13 includes a moving frame 131 and a gland frame 132 connected to one end of the moving frame 131, and a grease injection frame 133 is connected to the other end of the moving frame 131; wherein, the moving frame 131 is limitedly moved on the working frame 11, and at the same time, the moving frame 131 is connected to the rotating cam 125 in a rotating manner. The gland frame 132 and the grease injection frame 133 are respectively installed at both ends of the moving frame 131. When the moving frame 131 moves, it will drive the positions of the gland frame 132 and the grease injection frame 133 to change. Since the movement of the moving frame 131 is driven by the rotating cam 125, according to the circular motion of the rotating cam 125, the gland frame 132 and the grease injection frame 133 will move along an arc trajectory to ensure that they will not collide with other parts during the movement.

[0042] The gland part 14 includes a second hydraulic cylinder 141 and a gripping suction cup 143 connected to the second hydraulic cylinder 141, and a limiting column 142 is arranged on the gripping suction cup 143. The limiting column 142 is connected to the gland frame 132 in a limited sliding manner; wherein, the second hydraulic cylinder 141 is installed and fixed on the gland frame 132. A through-hole structure is opened on the gland frame 132 so that the limiting column 142 is installed in the through-hole to limit the movement of the limiting column 142. The second hydraulic cylinder 141 can drive the gripping suction cup 143 to move up and down.

[0043] The grease injection part 15 includes a rotating frame 151 and a driving gear 152 arranged inside the rotating frame 151, and a driven gear ring 153 is installed on the rotating frame 151. A grease storage tank 154 is installed on one side of the rotating frame 151, and a grease injection head 155 is installed on the other side of the rotating frame 151. Among them, the rotating frame 151 is installed at one end of the grease injection frame 133. By using the installation between the rotating frame 151 and the grease injection frame 133, the rotating frame 151 can rotate on the grease injection frame 133. At the same time, the driven gear ring 153 is installed inside the rotating frame 151, and the driving gear 152 is installed on the grease injection frame 133. The meshing connection between the driving gear 152 and the driven gear ring 153 can drive the rotating frame 151 to rotate, so as to make the grease injection work of the grease injection head 155 on the bearing more uniform.

[0044] Embodiment 2

[0045] Referring to Figure 2 and Figures 8 to 9 As shown, this is the second embodiment of the present invention. On the basis of Embodiment 1, the further improvement lies in: including a clamping assembly 20. The clamping assembly 20 includes a third hydraulic cylinder 21 and a second push rod 22 connected to one end of the third hydraulic cylinder 21, and transmission members 23 are connected to both ends of the second push rod 22. A clamping member 24 is connected to one end of the transmission member 23;

[0046] Among them, the third hydraulic cylinder 21 and the second push rod 22 are connected together by a fixed welding method. The third hydraulic cylinder 21 can drive the second push rod 22 to move horizontally. The transmission parts 23 are arranged at both ends of the second push rod 22, and the transmission parts 23 and the clamping parts 24 are connected by meshing. Therefore, the movement of the second push rod 22 driven by the third hydraulic cylinder 21 can make the clamping parts 24 move through the connection between the transmission parts 23 and the clamping parts 24, and clamp and fix the bearing.

[0047] The transmission part 23 includes a transmission moving rod 231 and a transmission sleeve rod 232 installed at one end of the transmission moving rod 231, and a second driven gear 233 is fixedly connected to the other end of the transmission sleeve rod 232. Among them, a clamping rod structure is arranged at one end of the transmission moving rod 231, a guiding groove structure is formed on the transmission sleeve rod 232, and the clamping rod structure on the transmission moving rod 231 is limited to move in the guiding groove structure on the transmission sleeve rod 232. When the second push rod 22 moves, it will drive the transmission moving rod 231 to move. By using the movement of the clamping rod structure on the transmission moving rod 231 inside the guiding groove of the transmission sleeve rod 232, the transmission moving rod 231 will rotate. At the same time, due to the fixed connection between the transmission sleeve rod 232 and the second driven gear 233, the second driven gear 233 will rotate synchronously.

[0048] The clamping part 24 includes a second rack 241 and a first clamping block 242 fixedly connected to one end of the second rack 241. A third rack 243 is arranged on one side of the second rack 241, and a second clamping block 244 is fixedly connected to one end of the third rack 243. Among them, the structures of the first clamping block 242 and the second clamping block 244 are the same, and the two are symmetrically arranged on both sides of the bearing placement table 32. The bearing is clamped and fixed by the movement of the first clamping block 242 and the second clamping block 244. At the same time, the second rack 241 and the third rack 243 are respectively connected to the upper and lower sides of the second driven gear 233 by meshing, so that the rotation of the second driven gear 233 will drive the second rack 241 and the third rack 243 to move in opposite directions, ensuring that the first clamping block 242 and the second clamping block 244 clamp the bearing.

[0049] The working principle of the present invention is:

[0050] First, the bearing is placed on the bearing placement table 32, and the seal cover is placed inside the seal cover placement table 33. At the same time, the third hydraulic cylinder 21 drives the second push rod 22 to move, and the transmission member 23 moves. Due to the movement of the clamping rod structure on the transmission rod 231 inside the guiding groove of the transmission sleeve rod 232, the transmission rod 231 will rotate. At the same time, due to the fixed connection between the transmission sleeve rod 232 and the second driven gear 233, the second driven gear 233 will rotate synchronously. Then, by using the meshing connection between the second rack 241 and the third rack 243 and the second driven gear 233, the first clamping block 242 and the second clamping block 244 move towards each other and clamp and fix the bearing.

[0051] After the bearing is fixed, by using the meshing connection between the driving gear 152 and the driven gear ring 153, the rotating frame 151 drives the grease injection head 155 to rotate. At the same time, the grease injection head 155 performs a grease injection operation on the bearing. At the same time, the gland pressing member 14 is located above the seal cover placement table 33. The second hydraulic cylinder 141 pushes the grasping suction cup 143 to move, sucks up the seal cover inside the seal cover placement table 33, and then raises the grasping suction cup 143 again after sucking it up.

[0052] After the grease injection is completed, the first hydraulic cylinder 121 pushes the first push rod 122 and the first rack 123 to move, and by using the meshing connection between the first rack 123 and the first driven gear 124, the first driven gear 124 drives the rotating cam 125 to rotate. Due to the rotational connection between the rotating cam 125 and the moving frame 131, the moving frame 131 drives the gland pressing member 14 and the grease injection member 15 to move along an arc trajectory. Finally, the gland pressing frame 132 drives the gland pressing member 14 to be located above the bearing placement table 32. The second hydraulic cylinder 141 pushes the grasping suction cup 143 again, so that the seal cover on the grasping suction cup 143 is correctly installed on the bearing, completing the processes of grease injection and gland pressing.
