Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly, in particular to a skid seat mechanism used for bearing assembly. Background Art

[0002] Insert ball bearings, also commonly known as external spherical bearings, belong to the category of deep groove ball bearings. Their characteristic is that the outer diameter surface of their outer ring is spherical, which can be matched with the corresponding concave spherical surface of the bearing seat (ball seat) to play a self-aligning role. However, each set of insert ball bearings is not used alone, but must be matched with the inner surface of the bearing seat for assembly. In the past, the installation of bearings into the bearing seat was done manually. Specifically, workers were required to pre-place the bearing into the bearing seat at a certain angle. Then, using a pry bar, one end of the pry bar was inserted into the inner cavity of the bearing. By prying the pry bar, the bearing was slowly pried into the bearing seat under the action of external force. Because this process cannot be completed in one go, it usually requires multiple adjustments to completely install the bearing into the bearing seat. However, there is currently no automated equipment on the market for this type of assembly work. Using manual methods alone will inevitably lead to high labor intensity for workers. At the same time, the assembly process is prone to uneven quality, resulting in a high defect rate of assembled products and reduced overall assembly efficiency.

DETAILED DESCRIPTION

[0021] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0022] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element. The terms "mounted", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0024] refer to Figure 1-3The utility model provides a pry seat mechanism for bearing assembly, including a workbench (not shown), a movable seat 1, a first driving device 2, a second driving device 3 and a pry bar 4. The movable seat 1 is arranged on one side of the workbench, the second driving device 3 is arranged on the movable seat 1, and the output end of the second driving device 3 is connected to the pry bar 4. The first driving device 2 can drive the movable seat 1 to move up and down; a workpiece fixing position (not shown) is provided on the workbench, and the workpiece fixing position is mainly used for placing the bearing seat; the second driving device 3 can drive the pry bar 4 to move back and forth toward the workpiece fixing position.

[0025] The pry seat mechanism provided by the present invention has the following specific working process: during use, a worker pre-places a bearing in a bearing seat to form a seated bearing, and then places the pre-installed seated bearing on a workpiece fixed position. At this time, the second drive device 3 drives the pry bar 4 to move in the direction of the workpiece fixed position until the pry bar 4 is inserted into the inner cavity of the bearing. The first drive member then drives the movable seat 1 to move up and down, and the process of the movable seat 1 moving up and down also drives the pry bar 4 to move up and down. Finally, the bearing is pried into the bearing seat through the up and down movement of the pry bar 4. The up and down movement of the pry bar 4 simulates the up and down prying action of a human hand, thereby achieving the assembly of the two. The pry seat mechanism provided by the present invention is mainly used for assembling between an outer spherical ball bearing and a bearing seat, and is particularly suitable for assembling between a P-type bearing seat and an outer spherical ball bearing.

[0026] The pry seat mechanism provided by the utility model has the following beneficial effects:

[0027] By simulating the manual action of prying the bearing and prying the bearing into the bearing seat through automated operations, the labor intensity of workers is further reduced. At the same time, automated operations are also more conducive to improving the assembly efficiency between the bearing and the bearing seat, reducing errors in the assembly process.

[0028] refer to Figure 1-3 In a preferred embodiment, a third driving device 5 is further included. The third driving device 5 is provided on the movable base 1. The third driving device 5 includes a driving source 50 (such as a cylinder) and a support plate 51. The support plate 51 extends upward relative to the movable base 1. The end of the support plate 51 close to the movable base 1 is hinged to the movable base 1. The end of the support plate 51 away from the movable base 1 is connected to the second driving device 3. The driving source 50 can drive the support plate 51 to swing relative to the movable base 1. By driving the swing of the support plate 51 by the driving source 50, the angle at which the pry bar 4 is inserted into the bearing can be adjusted. Figure 3Specifically, before the pry bar 4 is inserted into the inner cavity of the bearing, the insertion angle of the pry bar 4 can be adjusted by the driving source 50. Since the bottom end of the support plate 51 (the end close to the moving seat 1) is hinged to the moving seat 1, when the cylinder performs telescopic movement, it is equivalent to forming a thrust or a pull on the upper end of the support plate 51 (the end away from the hinge), so that the support plate 51 can swing relative to the moving seat 1. The swing mentioned here refers to the swing around the hinge (i.e. Figure 3 The left and right swing of the support plate 51 causes the tilt angle of the pry bar 4 to change. As shown in the figure, when the support plate 51 swings to the left, the pry bar 4 itself does not move, but its angle will tilt downward with the movement of the support plate 51. When the support plate 51 swings to the right, the angle of the pry bar 4 will tilt upward accordingly. In this way, the angle at which the pry bar 4 is inserted into the bearing cavity can be well adjusted.

[0029] refer to Figure 1-3 In a preferred embodiment, there are at least two support plates 51, which are spaced apart on the movable base 1. The third driving device 5 further includes a push plate 52, the two ends of which are connected to the two support plates 51 respectively. The driving source 50 is connected to the movable base 1 at one end and to the push plate 52 at the other end. The driving source 50 can drive the support plates 51 to swing toward the fixed position of the workpiece through the push plate 52. That is, when the driving source 50 is working, the force of the driving source 50 first acts on the push plate 52 and then is transmitted to the support plate 51. Moreover, by providing the push plate 52, the thrust or pull of the driving source 50 can be simultaneously transmitted to the two support plates 51, thereby achieving synchronous movement of the two and better stability.

[0030] refer to Figure 1-3In a preferred embodiment, the second drive device 3 includes a power source 30 and a fixed base 31, and the fixed base 31 is hinged to the support plate 51; the power source 30 is fixed to the fixed base 31, and a pry bar 4 is connected to its output end. In this embodiment, the power source 30 can be a cylinder, or a component such as an oil cylinder that can provide power to the pry bar 4, preferably a cylinder; during the assembly process, the angle at which the pry bar 4 is inserted into the bearing cavity can be adjusted by the third drive device 5, and then the power source 30 drives the pry bar 4 to move in the direction of the workpiece fixed position until the pry bar 4 is inserted into the bearing cavity; finally, the driving assembly drives the movable base 1 to move up and down, and the process of the movable base 1 moving up and down also drives the pry bar 4 to move up and down, thereby completely prying the bearing into the bearing seat. Specifically, when the front end of the pry bar 4 (the end near the workpiece fixing position) extends into the inner cavity of the bearing, it will partially abut against the inner wall of the bearing (equivalent to the contact point between the pry bar 4 and the inner wall of the bearing forming a support point). At this time, when the movable seat 1 moves up and down, driving the pry bar 4 up and down, the rear end of the pry bar 4 (the end connected to the drive source 50) will inevitably swing to a certain extent, that is, simulating the action of manually prying the bearing (i.e., manually inserting one end of the pry bar 4 into the inner cavity of the bearing, and then holding the other end of the pry bar 4 and prying up and down). Therefore, a hinged design is required between the fixed seat 31 and the support plate 51. This mechanical method well simulates the action of manually prying the seat, further reduces the labor intensity of manual labor, and at the same time improves the efficiency of assembly, and the quality of assembly is also more guaranteed.

[0031] refer to Figure 1-3 In a preferred embodiment, the first driving device 2 includes a base 20, and a power component 21 and a guide portion 22 provided on the base 20. The power component 21 is connected to the movable seat 1, and the power component 21 can drive the movable seat 1 to move up and down along the guide portion 22.

[0032] refer to Figure 1-3 In a further preferred embodiment, the guide portion 22 includes a guide rod 220 and a sleeve 221. The sleeve 221 is sleeved on the outside of the guide rod 220. One end of the guide rod 220 is connected to the base 20, and the other end extends upward relative to the base 20. The movable base 1 is slidably connected to the guide rod 220, and the power assembly 21 can drive the movable base 1 to reciprocate along the direction of the guide rod 220. In this embodiment, there are two guide rods 220, or multiple guide rods 220. The two guide rods 220 are spaced apart on the base 20, and the movable base 1 is connected to the two guide rods 220, which can improve stability during movement.

[0033] refer to Figure 1-3In a preferred embodiment, the power assembly 21 includes a motor 210 and a screw 211. The motor 210 is fixed to the base 20. One end of the screw 211 is connected to the motor 210, and the other end is connected to the movable base 1. The motor 210 can drive the movable base 1 to move up and down relative to the base 20 through the screw 211. Through the mutual transmission between the motor 210 and the screw 211, the screw 211 can convert the circumferential force of the motor 210 into an axial force, thereby driving the movable base 1 to move up and down, making the overall motion stroke of the movable base 1 more stable. In a further preferred embodiment, the power assembly 21 can also be a pneumatic cylinder or an oil cylinder.

[0034] In a preferred embodiment, a position sensor (not shown) is further provided on the base 20, which is electrically connected to the power assembly 21. The position sensor can detect the distance or stroke of the screw rod 211 moving up and down, thereby facilitating appropriate adjustments based on actual conditions.

[0035] In a preferred embodiment, a workpiece fixing device (not shown) is further included. The workpiece fixing device and the movable seat 1 are respectively located on either side of the workbench. The workpiece fixing device includes a cylinder and a pressure plate. The cylinder can drive the pressure plate to reciprocate toward the workpiece fixing position. In this embodiment, the pressure plate mainly serves to fix the bearing seat. During the assembly process, the pressure plate can first be used to fix the two ends of the bearing seat, and then the pry bar 4 can be inserted into the inner cavity of the bearing to perform the prying operation. This prevents the bearing seat from shaking or moving during the prying process, which may result in a poor assembly effect.

[0036] In a preferred embodiment, a pressure sensor (not shown) and a controller (such as a PLC controller) are also included. The pressure sensor, the first drive device, and the second drive device are all electrically connected to the controller. The controller is used to uniformly control the drive device of the assembly machine. The pressure sensor is set on the fixed seat, and the prying force (torque) of the prying rod during the prying process can be detected by the pressure sensor. Specifically, by detecting whether the torque in the actual process exceeds the set range value, the tightness of the assembly between the bearing and the bearing seat can be judged. During the assembly process, if the torque is too large, the assembly between the bearing and the bearing seat may be too tight; and if the torque is too small, the assembly between the two may be too loose. Whether it is too tight or too loose, it will affect the final assembly quality. Therefore, by setting a pressure sensor, the prying force can be better controlled within the appropriate range value to improve the assembly quality between the bearing and the bearing seat.
