Description

Technical Field

[0001] The utility model relates to the technical field of automated production, and more specifically, to automated equipment for press-fitting bearings. Background Art

[0002] In the assembly process of parts containing bearings, it is often necessary to first assemble the sleeve workpiece and the bearing, and then assemble the assembly with the main body. Since the bearing chamber of the sleeve workpiece and the bearing have an overfitting clearance, the bearing is usually placed manually, and then the bearing is usually pressed in by manual feeding using a press, or automatically pressing in one bearing at a time. During the initial alignment of the bearing chamber and the bearing of the sleeve workpiece, high coaxiality is required between the two. Pressing into the bearing chamber with an offset will cause certain damage to the bearing. There are also certain risks when manually feeding the press and pressing, and the press fitting depth may occasionally not be fully pressed. The manual operation is intensive and inefficient. In addition, the assembly of parts requires a high level of operator experience, which greatly increases the damage rate.

[0053] It should be noted that the embodiments of the present invention do not limit the specific shapes of the bearing hopper 201 and the kit hopper 401. In some embodiments, to achieve the purpose of individually loading bearings and kits, the bearing hopper 201 and the kit hopper 401 both adopt a strip-shaped groove structure. To enable automatic loading, they are configured to be inclined. The weight of the bearings and kits enables automatic unloading, reducing costs, ensuring individual loading, and lowering manufacturing costs.

[0054] In other embodiments, the purpose of single loading can also be achieved by using a loading machine to load the materials, such as using a bottle cap loading machine to load the bearings and the kit.

[0055] In addition, in the embodiment of the present invention, a control panel is installed on the frame 1 for controlling the parameters of each cylinder. At the same time, an electrical cabinet is provided on the frame 1, and pneumatic components, electrical components, power supplies, control boxes and other components are installed inside the electrical cabinet to realize the movement of the above-mentioned cylinders. This part is already a mature technology and will not be repeated here.

[0056] In addition, in the embodiment of the present invention, the stacking drive member 302 can automatically move downward at different intervals according to the number of bearings.

[0057] In some embodiments, a weight detector may be installed on the stacking drive 302 to adjust the required downward distance of different numbers of bearings by detecting different amounts of weight.

[0058] In other embodiments, a plurality of proximity switches 304 may be installed on the stacking drive 302 , and different bearings may interact with different proximity switches 304 to enable the stacking drive 302 to adjust the downward distance required for different numbers of bearings.

[0059] When in use, first install the bearing feeding assembly 2, the bearing stacking assembly 3, the kit feeding assembly 4 and the press-fitting assembly 5 on the frame 1, the bearing feeding assembly 2 is installed on the frame 1, the bearing feeding assembly 2 includes a bearing hopper 201 for storing bearings and a bearing feeding drive 202 for pushing bearings, the kit feeding assembly 4 includes a kit hopper 401 for storing kits and a kit feeding drive 402 for pushing kits, and then put the bearings and kits into the bearing hopper 201 and the kit hopper 401 respectively, and automatically unload them and automatically load them in the bearing feeding drive 202 and the kit feeding drive 402. The bearing stacking assembly 3 includes a bearing clamping drive 301 and the stacking drive 302, the bearing clamping drive 301 is used to clamp and feed the bearings pushed by the bearing feeding drive 202, the stacking drive 302 is located below the bearing clamping drive 301, and can drive the bearings to move upward or downward along the bearing axis direction, so as to complete the stacking of several bearings, and the stacked bearings are driven to the bottom of the press-fitting component 5, and under the action of the press-fitting component 5, several bearings are press-fitted into the kit at the same time, realizing precise synchronous and efficient press-fitting of multiple bearings, reducing operational safety hazards and product loss rate, significantly reducing equipment manufacturing and maintenance costs, greatly reducing enterprise production costs, and improving the degree of automation of production operations.

[0060] Please refer to Figure 2 and Figure 3 In some embodiments, the bearing feeding assembly 2 further includes a bearing feeding trough 203, a bearing unloading driving member 204 and a bearing shortage switch 205. The bearing feeding trough 203 is installed on the frame 1 and is located below the bearing hopper 201. The bearing feeding trough 203 is used to receive the bearings dropped from the bearing hopper 201, and a straightening limit plate 309 is provided at the connection position between the bearing feeding trough 203 and the bearing hopper 201 to limit the bearings so that they fall into the bearing feeding trough 203 and maintain a horizontal state. The bearing stacking assembly 3 is located at the end of the bearing feeding trough 203. The bearing feeding assembly 2 is used to push the bearings entering the bearing feeding trough 203. Towards the bearing stacking assembly 3, the bearing unloading drive 204 is installed on the frame 1 and is located at the end of the bearing hopper 201 close to the bearing feed trough 203, which is used to control the bearing to enter the bearing feed trough 203 from the bearing hopper 201, and push the bearing to the bearing stacking assembly 3 through the bearing unloading drive 204 to realize the loading action of the bearing. The bearing shortage switch 205 is installed on the bearing hopper 201 and is used to detect the remaining bearings in the bearing hopper 201. When the bearing shortage switch 205 detects that the remaining bearings in the bearing hopper 201 are insufficient or there are no bearings, an alarm will be issued to prompt the operator to replenish the bearings or check whether there is any jamming.

[0061] It should be noted that the bearing feed trough 203 in the embodiment of the present invention can adopt a strip groove structure, and its width can be adjusted. Specifically, two baffles are set on both sides of the bearing feed trough 203. By adjusting the distance between the two baffles, the purpose of rapid adjustment for different bearings can be achieved, which is suitable for feeding bearings of different sizes. The specific adjustment method is to adjust the distance between the two baffles by screwing the bolts, and the synchronous adjustment method of the baffles on both sides can ensure that the position of the bearing is accurate when loading it, avoiding bearing alignment deviation.

[0062] Please refer to Figure 2-Figure 6 In some embodiments, the bearing stacking assembly 3 also includes a stacking base 303 and a plurality of proximity switches 304. The stacking base 303 is installed on the stacking drive 302, and the stacking base 303 is controlled to move up and down by the stacking drive 302. That is to say, a plurality of bearings that need to be stacked are stacked on the stacking base 303. A plurality of proximity switches 304 are all installed on the stacking base 303 and arranged along the bearing stacking axis direction for detecting the positions of a plurality of stacked bearings. The detection of the number of stacked bearings is realized by the proximity switches 304, which is more accurate and different numbers of proximity switches 304 can be selected to be installed according to production needs.

[0063] It should be noted that in the embodiment of the present invention, the stacking base 303 adopts a plate-like structure. At the same time, in order to avoid interference with the clamping cylinder, the top height thereof is always slightly lower than the bottom height of the clamping plate 308.

[0064] Please refer to Figure 2-Figure 6 In some embodiments, the bearing stacking assembly 3 also includes a slide rail 305 and a loading drive 307. The slide rail 305 is installed on the frame 1. A loading slider 306 is slidably installed on the slide rail 305. The bearing clamping drive 301 is installed on the loading slider 306. The loading drive 307 is installed on the frame 1 and is used to control the loading slider 306 to slide along the slide rail 305. That is to say, through the cooperation of the slide rail 305 and the slider, when the bearing clamping drive 301 completes the clamping of the stacked bearings, the loading drive 307 is extended to push the slider toward the press-fitting assembly 5, thereby realizing the loading action of several stacked bearings.

[0065] Please continue to refer to Figure 2-Figure 6In some embodiments, two clamping plates 308 are installed on the bearing clamping drive 301, and the two clamping plates 308 are used to clamp several bearings to ensure that the bearings can be loaded normally. The two clamping plates 308 are provided with a limit plate 309 with elastic deformation function on the side close to each other. The limit plate 309 can prevent the bearings that have entered between the two clamping plates 308 from escaping during the stacking process of several bearings, ensuring that the bearings can be stacked smoothly. At the same time, the limit plate 309 can preliminarily limit the position of the bearing to avoid large axial deviation of the bearing.

[0066] It should be noted that the shape of the clamping plate 308 in the embodiment of the present invention can be selected into a suitable shape according to the clamped bearing. For example, the adjacent side of the clamping plate 308 can be set to a groove shape, and the contact area with the bearing is increased through the groove, thereby increasing the clamping force. At the same time, the groove of the clamping plate 308 can be designed as an arc-shaped structure to improve the coaxiality of several bearings.

[0067] In addition, in the embodiment of the present invention, anti-slip material, such as a rubber layer, a silicone layer, etc., needs to be provided on the adjacent surfaces of the two clamping plates 308.

[0068] Please continue to refer to Figure 6 In order to further enhance the supporting effect of the stacked bearings, in some embodiments, the bottom of the two clamping plates 308 are provided with support plates 310 for supporting the bearings, and the distance between the two support plates 310 is greater than the width of the base. That is to say, by providing the support plates 310 for supporting the stacked bearings at the bottom of the clamping plates 308, the risk of the stacked bearings falling after moving can be avoided.

[0069] It should be noted that in the embodiment of the present invention, the spacing width of the support plates 310 is greater than the width of the stacking base 303, so that the stacking base 303 can enter between the two support plates. After the final stage of stacking, the stacking base 303 will drop to a height lower than the support plates 310, ensuring that the clamping plate 308 can move smoothly.

[0070] In addition, the support plate 310 can be made of any hard material, such as stainless steel, iron, ceramic, etc. It can also be detachably mounted on the clamping plate 308 by bolts, or be integrally formed with the clamping plate 308.

[0071] Please refer to Figure 2In some embodiments, the kit feeding assembly 4 also includes a sleeve pressing platform 403, which is installed on the frame 1, and one end is located below the press-fitting assembly 5, and the other end is located below the kit hopper 401. The kit feeding drive 402 is used to push the kit on the sleeve pressing platform 403 to the bottom of the press-fitting assembly 5, that is, the press-fitting assembly 5 realizes the press-fitting between the bearing and the kit through the sleeve pressing platform 403, and at the same time, the kit will fall to the top of the sleeve pressing platform 403 through the kit hopper 401, and then be pushed to the bottom of the press-fitting assembly 5 through the kit feeding drive 402. The kit shortage switch 404 is installed on the kit hopper 401, and is used to detect the kit remaining in the kit hopper 401. The kit remaining is monitored by the kit shortage switch 404, and an alarm will be issued when there is a shortage of material to enhance the operator.

[0072] Please continue to refer to Figure 2 In order to prevent the kit from flipping over after falling onto the sleeve pressing platform 403, in some embodiments, the kit feeding assembly 4 also includes a kit limiting plate 405, which is installed on the kit hopper 401 and is located at the connection position between the kit hopper 401 and the sleeve pressing platform 403. That is to say, the kit is limited by the kit limiting plate 405 to prevent it from over-flipping and causing angular deviation.

[0073] It should be noted that in the embodiment of the present invention, the sleeve limiting plate 405 is a plate-like structure, the front section of which is arranged parallel to the sleeve hopper 401, and the rear section is arc-shaped and maintains a constant distance from the sleeve pressing platform 403.

[0074] Please refer to Figure 2 306, and the pressing assembly 5 starts to move, and the pressing assembly 5 starts to move. After the pressing is completed, the unloading drive 409 is installed on the frame 1, which is used to control the unloading slide 406 to slide along the slide rail 305. Under the action of the unloading drive 409, the pressed component is sent to the unloading position. The clamping drive 408 controls the two clamping fingers 407 to release the kit to complete the automatic unloading.

[0075] It should be noted that in the embodiment of the present invention, the two kit clamping fingers 407 can be in an arc shape, that is, the arc shape is coaxial with the press-fitting position of the kit and the bearing of the press-fitting assembly 5, thereby improving the initial positioning effect of the kit during the clamping process.

[0076] Please refer to Figure 2 In some embodiments, the press-fitting assembly 5 includes a bracket 501, a press-fitting column 503 and a positioning column 504. The bracket 501 is installed on the frame 1, and a press-fitting driver 502 is installed on the bracket 501. The press-fitting column 503 is installed at the protruding end of the press-fitting driver 502. The diameter of the press-fitting column 503 is larger than the diameter of the bearing. The positioning column 504 is installed at the end of the press-fitting column 503 away from the press-fitting driver 502 and is fixed coaxially with the press-fitting column 503. The maximum diameter of the positioning column 504 is the same as the inner diameter of the bearing. That is to say, during the press-fitting process, the press-fitting driver 502 is first actuated to drive the press-fitting column 503 to move downward, and the positioning column 504 first contacts the stacked bearings. At this time, the stacked bearings are clamped between the two clamps. Under the action of the holding plate 308, it maintains a roughly coaxial position and is moved to the top of the pressing platform 403 under the drive of the feeding slider. After the positioning column 504 contacts the bearing, it will be acted upon by the support plate 310 to make the positioning column 504 penetrate into the inner ring of the stacked bearings. At this time, the concentricity of the stacked bearings is completed. Then, the two clamping plates 308 move away from each other, that is, they are in an open state. At this time, the pressing column 503 continues to move downward, driving multiple stacked bearings into the interior of the kit. An inclination angle is provided at the inner ring of the contact position between the kit and the bearing to facilitate the bearing to enter the interior of the kit smoothly. When the stacked bearings are completely pushed into the interior of the kit by the pressing column 503, the assembly of the bearing and the kit is completed.

[0077] After the press-fitting is completed, in order to prevent the positioning column 504 from driving the pressed component to move during the resetting of the press-fitting column 503, in some embodiments, the maximum spacing of the clamping plates 308 is smaller than the maximum diameter of the kit. That is, the press-fitting component 5 is limited by the maximum opening spacing of the clamping plates 308 to prevent it from moving with the positioning column 504. In this way, after the press-fitting is completed, the positioning column 504 is reset to separate the positioning column 504 from the press-fitting component 5.

[0078] It should be noted that in the embodiment of the present invention, a limit plate 309 can also be installed on the bracket 501 to achieve the function of limiting the press-fit assembly 5, or the press-fit kit can be fixed through the action of the kit clamping finger 407, both of which can realize the separation of the positioning column 504 and the press-fit kit.

[0079] In order to further make it easier for the positioning column 504 to enter the inner ring of the bearing, in some embodiments, the side of the positioning column 504 away from the press-fitting column 503 is provided with a chamfer, that is, the side of the positioning column 504 away from the press-fitting column 503 is provided with a chamfer, so as to improve the flexibility of the positioning column 504 entering the inner ring of the bearing. The length of the positioning column 504 is less than the height of the kit. Limiting the length of the positioning column 504 can ensure that multiple stacked bearings can fully enter the interior of the kit to form a complete press-fitted assembly 5.

[0080] In order to further facilitate the adjustment of the size of the positioning column 504 according to different production requirements, in some embodiments, the positioning column 504 and the press-fit column 503 are detachably connected by threads. That is to say, the positioning column 504 with threaded connection can be conveniently replaced quickly by the user and selected for bearings of different sizes, which is conducive to improving the versatility of the equipment.

[0081] It should be noted that in the embodiment of the present invention, a boss can also be provided on the press-fit column 503, and a groove that cooperates with the boss can be provided on the positioning column 504. The positioning column 504 can be fixed to the press-fit column 503 through the interference fit of the boss and the groove.

[0082] It should be noted that each driving member mentioned in the embodiments of the present invention can realize the driving function by adopting an electric cylinder, a pneumatic cylinder or a hydraulic cylinder, or by adopting a motor screw structure to realize its driving function.
