Detailed implementation manners

[0018] The following further describes the present application in detail with reference to the attached Figures 1-7 drawings.

[0019] Embodiment An embodiment of the present application discloses a seat body sleeve pressing device. Referring to Figure 1 and Figure 2 , it includes a frame 1, a seat body positioning assembly 2, a bearing pressing assembly 3, and a seat body conveyor belt 4. Among them, the seat body conveyor belt 4 is arranged on the frame 1 for conveying the seat body. The bearing pressing assembly 3 is located above the seat body conveying line, while the seat body positioning assembly 2 is also arranged on the frame 1 and located below the seat body conveying line. The seat body positioning assembly 2 includes a mounting frame 201, a lifting member 202, and a positioning member 203. The mounting frame 201 is mounted on the frame 1 and located below the seat body conveying line. The lifting member 202 is a cylinder, and the positioning member 203 is mounted on the movable end of the lifting member 202. When it is necessary to position the seat body on the seat body conveyor belt 4, the lifting member 202 lifts the positioning member 203, so that the positioning member 203 can position the positioning seat on the seat body conveyor belt 4, so that the subsequent bearing pressing assembly 3 can smoothly press the bearing into the positioned seat body.

[0020] Referring to Figure 2 , Figure 3 and Figure 4, the seat conveyor belt 4 includes a driving roller 401, a driven roller 402, a second driving member 406, a connecting seat 405 and two transmission belts 403. The driving roller 401 and the driven roller 402 are respectively arranged at both ends of the rack 1 in the length direction, and the second driving member 406 is a driving motor. The output shaft of the second driving member 406 is coaxially connected to the driving roller 401, and the two transmission belts 403 are both wound around the driving roller 401 and the driven roller 402 and are parallel to each other. The connecting seat 405 is installed on the rack 1 and is located between the driving roller 401 and the driven roller 402. The upper surface of the connecting seat 405 is used to abut against the transmission belt 403 so as to support the part of the transmission belt 403 between the driving roller 401 and the driven roller 402 for transmitting the seat. An opening 404 for the positioning member 203 to pass through is further provided on the connecting seat 405. When the positioning member 203 is lifted by the lifting member 202, the positioning member 203 rises from the opening 404 on the connecting seat 405 and protrudes from the upper surface of the connecting seat 405, so as to be able to block the conveyed seat.

[0021] Referring to Figure 4 , Figure 5 and Figure 6 , the positioning member 203 includes a supporting portion 2031 and a limiting portion 2032. Among them, the limiting portion 2032 is used to block the conveyed seat, and the supporting portion 2031 is used to support the conveyed seat. A cavity 2034 is arranged in the supporting portion 2031, and a plug rod 2033 is arranged in the cavity 2034. When the plug rod 2033 extends out, it penetrates into the hole on the seat for pressing the bearing, so that the staff can sleeve the bearing on the plug rod 2033. At this time, the plug rod 2033 plays a guiding role for the bearing, so that when the subsequent bearing pressing assembly 3 presses the bearing, the bearing can be smoothly pressed into the seat under the guiding action of the plug rod 2033.

[0022] Furthermore, the opening 404 on the connecting seat 405 is an oblong hole, and the extending direction of the opening 404 is parallel to the conveying direction of the transmission belt 403. Two parallel connecting rods 2035 are vertically arranged on the side of the limiting portion 2032 close to the supporting portion 2031. The length direction of the two connecting rods 2035 is the same as the extending direction of the opening 404. The two connecting rods 2035 are respectively located on both sides of the plug rod 2033. The two connecting rods 2035 are respectively inserted into the supporting portion 2031 by means of plug-in fit and can move along their own axes on the supporting seat. This enables when replacing seats of different specifications (that is, the distance between the axis of the hole on the seat and the outer wall of the seat changes), the distance between the limiting portion 2032 and the supporting portion 2031 can be adjusted so that the plug rod 2033 can always penetrate into the hole on the seat when rising, achieving the effect of being applicable to seats of different size specifications.

[0023] Below the connecting support part 2031, a stop member 2036 is provided. The stop member 2036 is a setscrew. After the stop member 2036 is tightened, the stop member 2036 can abut against the outer wall of the connecting rod 2035 located in the support part 2031, so as to fix the protruding length of the connecting rod 2035 on the support seat, and further make the distance between the limiting part 2032 and the support part 2031 not easily change.

[0024] Refer to Figure 5 and Figure 6 , and the bearing pressing assembly 3 includes a vertical frame 301, a first driving member 302 and a pressing member 303. The vertical frame 301 is arranged on one side of the frame 1, and the first driving member 302 is installed at the upper end of the vertical frame 301. The first driving member 302 is a hydraulic cylinder. The movable end of the first driving member 302 is connected to the pressing member 303. The pressing member 303 is used to press the bearing into the hole on the seat body. A slot 3031 that can be inserted and matched with the insertion rod 2033 is also provided at the end of the pressing member 303 away from the first driving member 302. This makes it so that when the insertion rod 2033 guides the bearing, the insertion rod 2033 will not easily interfere with the downward pressing of the pressing member 303.

[0025] Furthermore, a driving rod 304 is provided at the end of the pressing member 303 close to the first driving member 302. A vertically placed sealing cylinder 305 is provided on the side of the vertical frame 301 close to the frame 1. The end of the driving rod 304 away from the first driving member 302 is located inside the sealing cylinder 305. A connecting pipeline 306 is provided on the sealing cylinder 305. The end of the connecting pipeline 306 away from the sealing cylinder 305 is communicated with the cavity 2034 inside the support part 2031. When the pressing member 303 is pressed downward under the action of the first driving member 302, the pressing member 303 drives the driving rod 304 to move together, and further makes the end of the driving rod 304 located inside the sealing cylinder 305 move inside the sealing cylinder 305 at the same time. This makes the driving rod 304 able to compress the space inside the sealing cylinder 305, and further makes the air inside the sealing cylinder 305 enter the cavity 2034 of the support part 2031 through the connecting pipeline 306, so as to eject the insertion rod 2033. When the bearing is completely pressed into the seat body by the pressing member 303, the insertion rod 2033 and the pressing member 303 are in an inserted and matched state.

[0026] Refer to Figure 1 , Figure 2 and Figure 5, To achieve the automatic feeding of bearings, a bearing feeding assembly 5 is also provided at the end of the frame 1. The bearing feeding assembly 5 includes a fixed frame 501, a guide sleeve 502, a magazine 503, a bearing conveying seat 504, and a pusher 505. Among them, the fixed frame 501 is provided on the frame 1, and the bearing conveying seat 504 is installed on the fixed frame 501. The length direction of the bearing conveying seat 504 is the same as the length direction of the frame 1. The guide sleeve 502 and the pusher 505 are respectively located at both ends of the bearing conveying seat 504 in the length direction. The guide sleeve 502 is installed on the vertical frame 301 and is located between the pressing member 303 and the positioning member 203. The guide sleeve 502 is provided with a feeding port 5021 for the bearing to enter, and the pusher 505 is installed at one end of the bearing conveying seat 504 away from the guide sleeve 502. The pusher 505 is a cylinder, and a push block is installed at the movable end of the pusher 505. The magazine 503 is used to place the bearings, and the magazine 503 is installed at one end of the bearing conveying seat 504 close to the pusher 505. When the pusher 505 is started, the pusher 505 can push the bearing on the bearing conveying seat 504 towards the direction of the guide sleeve 502. At this time, the bearing enters the guide sleeve 502 through the feeding port 5021 of the guide sleeve 502 and falls on the bearing of the positioning member 203.

[0027] It should be noted that the inner diameters on both sides of the feeding port 5021 on the guide sleeve 502 are adapted to the outer diameter of the bearing pushed by the pusher 505, which enables the bearing to enter the guide sleeve 502 through the feeding port 5021 and not easily flip during the falling process.

[0028] When the pressing member 303 presses the bearing, it will enter the guide sleeve 502 until the bearing in the guide sleeve 502 is completely pressed into the seat body. To avoid interference between the driving rod 304 on the pressing member 303 and the guide sleeve 502 during the downward pressing process of the pressing member 303, an opening 404 groove with an extending direction consistent with the length direction of the guide sleeve 502 is also provided at the position corresponding to the driving rod 304 on the guide sleeve 502.

[0029] Refer to Figure 2 and Figure 7 , Further, a sliding portion 5022 is also provided on the outer wall of the guide sleeve 502 close to the vertical frame 301, and a sliding groove 3011 adapted to the sliding portion 5022 is provided on the vertical frame 301. The sliding groove 3011 is a dovetail groove, and the extending direction of the sliding groove 3011 is the same as the height direction of the vertical frame 301. This enables the guide sleeve 502 to adjust its height between the pressing member 303 and the positioning member 203. When the positioning member 203 is jacked up to the highest position, the distance between the guide sleeve 502 and the positioning member 203 is adjustable, and thus it can be applicable to seat bodies of different thicknesses.

[0030] In order to fix the height of the guide sleeve 502 on the vertical frame 301, a fixing bolt 5023 is provided on the sliding part 5022. The fixing bolt 5023 is connected to the sliding part 5022 by means of screw fit. And the end of the fixing bolt 5023 can be abutted against the bottom surface of the sliding groove 3011 after passing through the sliding part 5022, so as to fix the position of the sliding part 5022 in the sliding groove 3011, thereby realizing the fixation of the height of the guide sleeve 502 on the vertical frame 301.

[0031] The implementation principle of the embodiment of the present application is as follows: blanks are loaded at one end of the blank conveyor belt 4 of the seat body. At this time, under the lifting of the lifting member 202, the limiting part 2032 of the positioning member 203 protrudes from the upper surface of the connecting part, and the blank will be blocked by the limiting part 2032 during transportation. Subsequently, the pushing member 505 will push out the lowermost bearing in the bin 503, so that the bearing enters the guide sleeve 502, and then falls onto the blank blocked by the limiting part 2032 through the guide sleeve 502. Immediately afterwards, under the action of the first driving member 302, the pressing member 303 moves towards the inside of the guide, and at the same time drives the driving rod 304 to move together. During the movement, the end of the driving rod 304 located in the sealing cylinder 305 compresses the space in the sealing cylinder 305, and then the air in the sealing cylinder 305 is conveyed through the communication pipeline 306 to the cavity 2034 of the limiting part 2032, so that the insertion rod 2033 extends out of the hole in the blank to play a guiding role for the bearing falling on the blank. Subsequently, the slot 3031 on the pressing member 303 and the insertion rod 2033 are connected by means of plug-in fit, and then the bearing is pressed into the blank under guidance.

[0032] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
