Description

Technical Field

[0001] The utility model relates to the field of industrial manufacturing, and more particularly to a bearing assembly assembly device. Background Art

[0002] In the machinery manufacturing industry, the assembly of bearing components is a critical and complex process, whose quality and efficiency directly impact the overall performance and production costs of the product. Traditional bearing assembly relies heavily on manual labor, resulting in high labor intensity, low assembly precision, and low production efficiency. These issues are particularly prominent in sectors requiring high assembly precision, such as automotive manufacturing and precision instruments.

[0003] To overcome the shortcomings of traditional assembly methods, automated assembly equipment is becoming a mainstream trend in the industry. However, existing automated bearing assembly equipment still has some limitations in design and functionality. For example, it cannot achieve continuous automated operation, which limits overall assembly efficiency.

[0004] At the same time, traditional press-fitting methods often use a rigid connection structure, which makes it impossible to effectively compensate for assembly errors caused by factors such as part size errors and position deviations during the press-fitting process, thereby affecting assembly accuracy and product quality; rigid connection also easily causes the equipment to produce large impacts and vibrations during the press-fitting process, causing damage to the equipment itself and the parts to be assembled. Utility Model Content

[0005] The utility model overcomes the deficiencies of the prior art and provides a bearing assembly assembly device with a simple structure, reasonable design, reduced manual intervention, improved production efficiency, increased output, improved production quality, and less risk of damage to equipment and parts.

[0006] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0007] A bearing assembly assembly device includes a bearing press module and a transfer module; the transfer module includes a transfer turntable, a transfer drive device for driving the transfer turntable to rotate, and a positioning tool arranged on the transfer turntable; the bearing press module includes a bearing press assembly and a bearing press drive device that drives the bearing press assembly to perform press work; the bearing press assembly includes a connecting piece connected to the bearing press drive device, a positioning piece that cooperates with the positioning tool during bearing press fitting, and a connecting piece that connects and cooperates the connecting piece with the positioning piece; the connecting piece is floatingly connected to the connecting piece and can float in the horizontal and vertical directions, and the positioning piece is floatingly connected to the connecting piece and can float in the vertical direction. Beneficial effects

[0008] In the present invention, the automated assembly process of the equipment is realized through the work and cooperation of the bearing press module and the transfer module, which reduces manual intervention and thus greatly improves production efficiency and output; at the same time, this automated operation mode further avoids the delays and errors that may be caused by manual operation, making the production rhythm more stable and efficient; and also ensuring the quality of production.

[0009] When a fit error occurs between the bearing press assembly and the positioning tooling during the bearing press-fitting process of this equipment, the floating connection between the various components of the bearing press-fitting assembly can be used for adjustment to ensure a tight and stable fit between the two. This can minimize the possibility that the positioning parts and connectors are not fully calibrated with the positioning tooling during the bearing press-fitting process, resulting in tilting and damage to the bearing, the bearing press assembly or the positioning tooling. This will make it less likely that this equipment will cause damage to the equipment and parts during the press-fitting process. BRIEF DESCRIPTION OF THE DRAWINGS

The axial directions of the floating core shaft 161 and the floating installation space 144 correspond to each other. The central axis of the mounting column 145 is in the same straight line as the central axis of the floating installation space 144. The floating core shaft 161 includes a first area 164 that cooperates with the mounting seat 143 and a second area 165 that cooperates with the connecting shaft 162. The second area 165 is connected to the top of the connecting shaft 162. The first area 164 is in the floating installation space 144. A floating connection through hole 166 is provided at the top of the first area 164. The top of the mounting column 145 is connected to the inner wall of the top of the floating installation space 144. The bottom end of the column 145 passes through the floating connection through hole 166 and enters the floating connection space 163; the bottom end of the mounting column 145 is provided with a spring seat 146, and the area of ​​the mounting column 145 in the floating connection space 163 is provided with a first floating spring 147, and the two ends of the first floating spring 147 are respectively in contact with the spring seat 146 and the inner wall of the top of the floating connection space 163; it is worth noting that the two ends of the first floating spring 147 can also be directly connected to the spring seat 146 and the inner wall of the top of the floating connection space 163 to improve the tightness of the fit; the diameter of the first area 164 is less than The inner diameter of the floating installation space 144, when the floating core shaft 161 is matched with the mounting seat 143, there is a gap between the outer wall of the first area 164 and the inner wall of the floating installation space 144; the diameter of the mounting column 145 is smaller than the inner diameter of the floating connection through hole 166, and there is a gap between the mounting column 145 and the inner wall of the floating connection through hole 166; the diameter of the spring seat 146 is smaller than the inner diameter of the floating connection space 163, and there is a gap between the outer wall of the spring seat 146 and the outer surface of the first floating spring 147 and the inner wall of the floating connection space 163; thereby providing sufficient space for the floating of the connecting member 16.A floating mounting groove 167 is provided on the outer surface of the first area 164 along its circumference, and a floating elastic ring 168 is provided in the floating mounting groove 167, and the inner and outer surfaces of the floating elastic ring 168 respectively abut against the first area 164 of the floating core shaft 161 and the inner wall of the floating mounting space 144; the number of the floating mounting grooves 167 is at least two, and they are parallel to the horizontal plane; by arranging the floating mounting space 144 and the floating connection space 163 in the connecting member 14 and the connecting member 16, and equipping them with corresponding floating springs and floating elastic rings 168, small position deviations and assembly errors can be automatically calibrated during the bearing press-fitting process; the pressing accuracy is improved, and the stability of the pressing process is enhanced, and the poor pressing effect and damage to equipment and parts caused by assembly errors are avoided as much as possible.

[0037] In this embodiment, a third area 169 is provided between the first area 164 and the second area 165. When the bearing is pressed into the workpiece, the bottom end of the mounting seat 143 contacts the third area 169. The contact surfaces between the third area 169 and the mounting seat 143 and the third area 169 are all smooth arc surfaces; thereby, after the connecting member 16 and the connecting member 14 are floatingly connected, they can be more stable when floating in the horizontal direction, and the floating process is smoother.

[0038] In this embodiment, an auxiliary floating space 174 communicating with the floating connection space 163 is also provided at the top of the connecting shaft 162, so that when the connecting member 16 floats vertically, the mounting column 145 has more space to move, thereby reducing the possibility of interference and damage between the connecting shaft 162 and the mounting column 145 as much as possible.

[0039] In the present invention, a floating fit space 170 is provided in the connecting shaft 162, and a floating fit opening 171 of the floating fit space 170 is provided at the bottom of the connecting shaft 162; the positioning member 15 includes a ejector pin 151, and the ejector pin 151 is movably provided in the floating fit space 170; the ejector pin 151 includes a fitting portion 152 and a positioning portion 153; the fitting portion 152 is movably fitted with the floating fit space 170; the positioning portion 153 is at the bottom end of the fitting portion 152, and is positioned and fitted with the positioning tool 33 during the bearing press-fitting process; the floating fit A second floating spring 173 is provided in the space 170, and the two ends of the second floating spring 173 are respectively connected to the top of the mating portion 152 and the inner wall of the top of the floating mating space 170; the design of the ejector pin 151 enables precise positioning and mating with the positioning tool 33 during the bearing press-fitting process, ensuring the accurate installation of the bearing; at the same time, the setting of the floating mating space 170 and the second floating spring 173 allows the ejector pin 151 to be partially retracted into the floating mating space 170 during the press-fitting process to adjust the position, thereby avoiding damage to the ejector pin 151 and the positioning tool 33 during press-fitting.

[0040] In this embodiment, the diameter of the mating portion 152 is smaller than the diameter of the connecting shaft 162, and the diameter of the mating portion 152 corresponds to the inner diameter of the bearing inner ring; the diameter of the positioning portion 153 is smaller than the diameter of the mating portion 152; and therefore, during the bearing press-fitting process, when the mating portion 152 retracts into the floating mating space 170, no force will be applied to the bearing, thereby preventing the mating portion 152 from affecting the installation of the bearing.

[0041] In the present invention, the bearing press assembly 11 also includes a bearing grabbing portion 17, which includes a bearing clamping ring 175. The bearing clamping ring 175 is movably sleeved on the end of the connecting shaft 162 away from the floating core shaft 161; the outer surface of the connecting shaft 162 is provided with an assembly extension block 176, and the connecting shaft 162 is also sleeved with a third floating spring 177, and the two ends of the third floating spring 177 are respectively connected to the assembly extension block 176 and the top of the bearing clamping ring 175; the bearing grabbing portion 17 also includes a ball The head plunger 178, the ball head plunger 178 is arranged at the bottom end of the bearing retaining ring 175; when the third floating spring 177 is extended, the height of the ball head plunger 178 is lower than the height of the bottom end of the connecting shaft 162, and the height difference and cooperation between the two form a bearing grasping space 179; the design of the bearing grasping part 17 realizes the automatic grasping and releasing function of the bearing; through the coordinated use of the third floating spring 177 and the ball head plunger 178, a bearing grasping space 179 is formed, which can reliably grasp and fix the bearing. During the press-fitting process, as the connecting shaft 162 moves vertically driven by the bearing press-fitting drive device 12, the bearing retaining ring 175 and the ball plunger 178 will adjust their positions accordingly. First, the bearing is smoothly grasped through the bearing grasping space 179, and then continuously pressed down after grasping the bearing. Since the bearing retaining ring 175 is continuously pressed down during the press-fitting process, the bottom of the bearing retaining ring 175 will abut against the workpiece or the positioning tool 33, causing the bearing retaining ring 175 to rise relative to the connecting shaft 162, and at the same time the third floating spring 177 is compressed. At this time, the ball plunger 178 shrinks under the force generated by the contact bearing as the bearing retaining ring 175 rises, thereby releasing the bearing and completing the press-fitting process of the bearing; after completing the press-fitting process, the bearing retaining ring 175 is reset under the action of the third floating spring 177.

[0042] In this embodiment, the central axes of the fitting portion 152, the positioning portion 153, the floating fitting space 170, the connecting shaft 162 and the bearing retaining ring 175 are on the same straight line, thereby making the overall structure more uniform and facilitating the transmission of the press-fitting force.

In this embodiment, the confined spaces 181 are all arranged horizontally, so that the connecting member 16 is in a vertical state as a whole; when there is no horizontal floating between the connecting member 16 and the connecting member 14, the mating portion 152, the positioning portion 153, the floating mating space 170, the connecting shaft 162, the bearing retaining ring 175, the mounting seat 143, the mounting column 145, the floating core shaft 161 and the center point 144 of the floating mounting space are on the same straight line.
