[0018] Compared with the prior art, the present invention provides an automatic pressing machine for washing machine bearings, which has the following features:

[0019] Beneficial effects:

[0020] In the technical solution disclosed in the present invention, the inner cylinder that needs to be pressed into the bearing is placed on a turntable, and the inner cylinder is circumferentially transferred based on the rotation of the turntable, thereby generating circumferential route processing, and the fillers and the press-fitting parts are arranged on the transfer route. On the one hand, several parts of the combined bearing can be placed in the inner cylinder in the conveying direction, and the several parts can be pressed by the press-fitting parts in combination with the conveying direction to achieve the combination of the bearing in the inner cylinder. On the other hand, the fillers and the press-fitting parts are arranged on the conveying route of the inner cylinder. With the coordination of the fillers and the press-fitting parts in the sequence, independent operation steps can be formed, thereby reducing the replacement cost when a single part is damaged.

[0021] Based on the support assembly described in the present invention, the inner cylinder is arranged on the top plate by utilizing the arrangement of the bottom plate and the top plate. Thus, when the top plate is adjusted in relative height with respect to the bottom plate, the inner cylinder arranged on the top plate will also be raised in height relative to the filler and the pressing part. When the pressing part applies downward pressure on the bearing part structure placed in the inner cylinder by utilizing the change in height, a pushing force is generated, thereby realizing the role of cooperating with the pressing part and increasing its efficiency in the pressing process.

[0022] Based on the explanation of the present invention, the feeding end head is rigidly connected to the bushing and is arranged in an L-shape. The arrangement of the feeding end head increases the diameter range of its feeding and increases the alignment effect with the discharge bin opening during rotation. The driving force generated when the feeding end head moves acts on the baffle plate, thereby forcing it to move along an arc track, causing the discharge bin opening to be in an open state. As a result, the outer bearing will fall due to gravity and directly fall onto the connecting plate. After the connecting plate rotates with the central axis, it can be directly adsorbed by the electric push rod and then filled in the inner cylinder, thereby increasing the filling efficiency.

[0030] See also Figure 1-Figure 5 The present invention is specifically aimed at the existing technical problems. At present, the drum washing machine needs a combined bearing. An outer bearing is arranged at the top of the inner drum 2, and an inner bearing is arranged below it and sealed with a sealing ring. For this combined bearing, the technicians in this field will make the following design: one pressing device presses one bearing, and several workers are required to work at the same time. This design scheme requires a large amount of labor and is not efficient. The bearing pressing process takes a long time and is inefficient. Based on the above problems, this scheme describes an automatic pressing machine for washing machine bearings, which places the inner cylinder 2 that needs to be pressed on the turntable, and generates circumferential transfer of the inner cylinder 2 based on the rotation of the turntable, thereby generating circumferential route processing, and arranges the filler 4 and the pressing member 5 on the transfer route. On the one hand, it is possible to place several parts of the combined bearing in the inner cylinder 2 in the conveying direction, and use the pressing member 5 to press several parts in combination with the conveying direction to achieve the combination of the bearing in the inner cylinder 2. On the other hand, the filler 4 and the pressing member 5 are arranged on the conveying route of the inner cylinder 2. Under the coordination of the filler 4 and the pressing member 5 in sequence, independent operation steps can be formed, thereby reducing the replacement cost when a single part is damaged.

[0031] A specifically described automatic bearing pressing machine for a washing machine includes a support frame 1 for supporting a processing chamber to lift it to a corresponding height, a rotating member 3 for driving an inner drum 2 to rotate so as to perform the operation steps of adding parts and pressing parts at a preset position is arranged in the processing chamber, the rotating member 3 includes a turntable 31 installed in the processing chamber for setting the rotation radius of the inner drum 2, a support assembly 32 for supporting the inner drum 2 is arranged at an upper end of the turntable 31 and is equidistantly installed in an annular direction, a packing member 4 and a pressing member 5 are arranged on the rotation radius of the turntable 31, and the pressing member 5 is installed at The telescopic rod on the top plate of the processing chamber first places the inner cylinder 2 on the turntable 31, and uses the support assembly 32 to support the weight of the turntable 31. Then, the rotation of the turntable 31 is used to drive the inner cylinder 2 to change its own position, gradually approaching the filling piece 4 and the pressing piece 5 until it moves to the lower end thereof. After the filling piece 4 fills the outer bearing into the inner cylinder 2 and after the filling is completed, the support assembly 32 gradually installs the inner bearing and the sealing ring to the lower end of the outer bearing. After completing this step, the pressing piece 5 is used to press the filled parts to complete the overall bearing pressing.

[0032] In order to increase the height adjustment of the inner cylinder on the pressing part 5 and the filling part 4, a support assembly 32 is provided, which includes a bottom plate 321 installed on the turntable 31 and a top plate 322 arranged on the bottom plate 321, the inner cylinder 2 is placed on the top plate 322, a support structure 323 is arranged between the top plate 322 and the bottom plate 321, the support structure 323 between the top plate 322 and the bottom plate is distributed at the four corners of the bottom plate, the support structure 323 includes a base plate and a lifting shaft installed on the base plate, a partial structure of the lifting shaft is embedded in a bushing arranged on the base plate, a driving member for pushing the lifting shaft up and down is arranged in the bushing, so as to cause the top plate 322 to be raised relative to the height of the bottom plate. By utilizing the arrangement of the bottom plate 321 and the top plate 322, the inner cylinder 2 is arranged on the top plate 322. Thus, when the top plate 322 is adjusted in relative height with respect to the bottom plate 321, the inner cylinder 2 arranged on the top plate 322 will also be raised in height relative to the filler 4 and the pressing piece 5. By utilizing the change in height, when the pressing piece 5 applies downward pressure to the bearing structure placed in the inner cylinder 2, a pushing force is generated, thereby achieving the function of cooperating with the pressing piece 5 and increasing its efficiency during the pressing process. The top plate 322 is provided with a through hole, and a lifting rod 324 is installed on the bottom plate 321, extending through the through hole to the top plate 322 and connected to the inner tube 2.

Two lifting rods 324 are symmetrically arranged front and back, and the installation range of the two lifting rods 324 does not exceed the opening width of the through hole. Linear guide rails 328 are installed on the front and rear side walls of the through hole. The slide plate 325 It is installed between the two linear guides 328 and connected to the automatic end of the linear guides 328. A receiving groove is provided at the connecting position of the slide plate 325 and the two lifting rods 324. The depth of the receiving groove satisfies the maximum distance that the slide plate 325 can move relative to the lifting rods 324 when driven by the linear guides 328. A driving motor is installed between the lower end of the turntable 31 and the processing chamber to drive the rotation of the turntable 31. The front end face of the processing chamber is open, and the other end faces are provided with end plates for side-enclosed working environment.

[0033] In order to facilitate the addition of assembled bearings in the inner cylinder one by one, a packing column is provided in the rotating part.

The packing column specifically includes a packing column 1 326 and a packing column 2 327. The packing column 1 326 and the packing column 2 327 are respectively sleeved with the inner bearing and the sealing ring of the bearing. The inner bearing and the outer bearing are first pressed together by pushing the packing column 1 326 and the packing column 2 327 by the pressing member 5. Then, when the packing reaches the bearing installation position after movement, the sealing ring is pressed together on the inner bearing by the pressing member 5 and the packing column 2 327, thereby completing the pressing of the entire bearing. The filling member 4 is arranged on the rotation track of the turntable 31, and an electric push rod 41 for pushing the outer bearing into the inner cylinder 2 is installed at the upper end of the turntable 31, and the electric push rod 41 is installed on the top plate of the processing bin. A vacuum adsorption head is installed at the end of the electric push rod 41, and the outer bearing is adsorbed on the vacuum adsorption head and then filled into the inner cylinder 2. A feeding member 42 for providing the outer bearing to the electric push rod 41 is arranged at one end of the electric push rod 41. The feeding member 42 includes a screw rod 421 installed on the side wall of the bin body, a synchronous block 422 and a material taking end 423 installed on the synchronous block 422 are installed on the free end of the screw rod 421, and the material taking end 423 is installed on the synchronous block 422.

A driving motor for driving the central shaft to rotate is installed on the synchronous block 422, and the material taking end 424 rotates circumferentially under the drive of the central shaft, and A material storage bin 43 installed on the left side wall of the processing bin is provided on the rotating track. The material storage bin 43 provides space for accommodating an external bearing. An elastic baffle 45 for establishing or releasing an external bearing output channel is installed at the bottom of the material storage bin 43. The material collection end 423 includes a bushing sleeved on the central axis and a material collection end head 424 installed on the lower end of the bushing. The material collection end head 424 is rigidly connected to the bushing and is L-shaped. The setting of the material collection end head 424 increases the diameter range of its material collection and increases its alignment effect on the discharge bin port during rotation. A connecting plate is provided at the cutoff end of the material collection end head 424 for receiving the external bearing placed thereon. After the material collection end head 424 completes material collection, the external bearing is adsorbed thereon by using a vacuum adsorption head installed on the electric push rod 41, and after placing it in the inner cylinder 2, the adsorption force on the external bearing is released to complete the filling.

[0034] In order to increase the material supply to the material picking end 423, thereby improving the filling efficiency of the electric push rod 41 into the inner cylinder 2, arc-shaped tracks 44 are installed on the left and right side walls of the storage bin 43, and a baffle 45 for covering the material discharge port of the storage bin 43 is slidably installed on the arc-shaped track 44. The baffle 45 slides on the arc-shaped track 44 as the material picking end head 424 pushes, and a compression spring is installed between the rear end of the baffle 45 and the inner wall of the arc-shaped track 44 for resetting the baffle 45 and thus restoring the state of covering the port of the material picking bin 43. In addition, protrusions are provided on the left and right ends of the baffle 45, and an inner groove opposite to the protrusion is opened on the inner wall of the arc-shaped track 44 for cooperating with the sliding of the protrusion. At the same time, in order to increase the effective contact of the baffle 45 with the material picking end head 424 during movement, an extension rod block is provided at one end of the baffle 45, and the thickness of the extension block is not less than the height difference between the arc-shaped track 44 and the baffle 45. The driving force generated when the material picking end 424 moves acts on the baffle 45, thereby forcing it to move along the arc track 44, causing the discharge bin opening to be in an open state. As a result, the outer bearing will fall due to gravity and fall directly onto the connecting plate. After the connecting plate rotates with the central axis, it can be directly adsorbed by the electric push rod 41 and then filled into the inner cylinder 2.
