Technical Field

[0001] The invention relates to the technical field of bearing installation, and in particular to a bearing sleeve press-fitting device and a bearing installation machine. Background Art

[0002] At present, in the air-conditioning motor industry, AC and DC motor rotor sleeve bearings and automatic bearing pressing are performed manually. Because the inner ring of the bearing and the rotor adopt an interference fit, the bearing needs to be manually inserted into the upper and lower rotors during assembly, and then the bearing with the rotor is inserted into the mold. The bearing is then pressed against the rotor retaining spring by the force applied to the inner ring of the bearing to complete the rotor bearing assembly.

[0003] The above-mentioned installation method of bearings and rotors has the following disadvantages:

[0004] Since the bearing needs to be positioned manually before being inserted into the rotor, it is time-consuming, and the bearing and the rotor can only be installed manually in one pass, or the rotor can be press-fitted in one pass, which is inefficient. Summary of the invention

[0005] The purpose of the present invention is to avoid the deficiencies in the prior art and provide a bearing sleeve press-fitting device, which can quickly and accurately assemble the bearing and the rotor, and has the advantages of saving manpower and high effect.

[0006] To achieve one of the above purposes, the present invention provides the following technical solutions:

[0009] The positioning mold is provided with a positioning cavity. By constructing the positioning cavity into the outer shape of a bearing, the bearing can be better positioned, so that the positioned bearing can be accurately assembled with the rotor, saving manpower for alignment.

[0010] A pushing component, wherein the pushing direction of the pushing component points to the entry port, is used to push the bearing into the positioning cavity.

[0011] Since the pushing direction of the pushing component points to the entrance, by placing the bearing at the entrance, the pushing component can quickly and accurately push the bearing into the positioning cavity to achieve positioning of the bearing.

[0012] In some embodiments, a workbench is further included, the positioning mold and the pushing assembly are both arranged on the workbench, the pushing assembly is pushed along the plane extension direction of the workbench, and the entrance is opposite to the pushing direction of the push rod.

[0013] The positioning mold and the pushing component are both arranged on the workbench, so that the positioning mold and the pushing component are both located on the workbench, which facilitates the positioning mold and the pushing component to quickly move the bearing into the positioning cavity on a table.

[0014] In some embodiments, the pushing assembly includes a push rod and a slide groove provided on the workbench.

[0015] The slide groove is connected to the entrance, and a plurality of bearings can be placed in the slide groove. The bearings in the slide groove slide along the slide groove to the entrance, and the push rod pushes the bearings at the entrance into the positioning cavity.

[0020] In some embodiments, one side of the slide groove is connected to an input plane, and the bearing falls into the slide groove along the input plane.

[0021] Multiple bearings can be placed simultaneously through the input plane, and because the length direction of the input plane is equivalent to the length direction of the chute, the bearings can be transferred to the chute conveniently and quickly, thereby improving the feeding efficiency.

[0024] In some embodiments, a plurality of bearing limit openings are opened on the top surface of the storage chamber, and the bearing enters the storage chamber from each bearing limit opening, and each bearing limit opening is connected with a positioning rod, and the positioning rod is inserted into the hollow position of the bearings stacked on each limit opening and is located above the bearing limit opening.

[0025] The bearing limit opening provides an entry position for the bearing.

[0028] In some embodiments, the push-feeding structure includes a push plate, and the push plate is connected to a first cylinder, and the first cylinder drives the push plate to push the bearing in the storage chamber.

[0046] Example 1

[0047] At present, in the air-conditioning motor industry, the AC and DC motor rotor sleeve bearing 6 and the automatic pressing of the bearing 6 are performed manually; because the inner ring of the bearing 6 and the rotor adopt an interference fit, during assembly, it is necessary to manually insert the bearing 6 into the upper and lower rotors, and then put the bearing 6 with the rotor into the mold, and then press the bearing 6 tightly against the rotor retaining spring by the inner ring of the bearing 6 to complete the assembly of the rotor bearing 6.

[0048] The above-mentioned installation method of the bearing 6 and the rotor has the following disadvantages:

[0049] Since the bearing 6 needs to be positioned manually before being inserted into the rotor, it is time-consuming, and the bearing 6 and the rotor can only be installed manually in one pass, or the rotor can be pressed in one pass, which is inefficient.

[0050] In view of the above technical problems, the bearing 6 disclosed in this embodiment is inserted into the press-fitting device, please refer to Figure 1 ,include:

[0052] The positioning mold 1 is provided with a positioning cavity 2. By constructing the positioning cavity 2 into the shape of the bearing 6, the bearing 6 can be better positioned, so that the positioned bearing 6 can be accurately assembled with the rotor, saving manpower for alignment.

[0053] A pushing component, the pushing direction of which points to the entry port 3 , is used to push the bearing 6 into the positioning cavity 2 .

[0054] Since the pushing direction of the pushing component points to the entrance 3, by placing the bearing 6 at the entrance 3, the bearing 6 can be quickly and accurately pushed into the positioning cavity 2 by the pushing component to achieve positioning of the bearing 6.

[0055] According to a bearing 6 sleeve press-fitting device as described in claim 1, it is characterized in that it also includes a workbench 4, the positioning mold 1 and the pushing assembly are both arranged on the workbench 4, the pushing assembly is pushed along the plane extension direction of the workbench 4, and the entry port 3 is opposite to the pushing direction of the push rod.

[0056] The positioning mold 1 and the pushing assembly are both arranged on the workbench 4, so that the positioning mold 1 and the pushing assembly are both located on the workbench 4, which facilitates the positioning mold 1 and the pushing assembly to quickly move the bearing 6 into the positioning cavity 2 on a table.

[0057] In this embodiment, the pushing assembly includes a push rod and a slide groove 5 provided on the workbench 4.

[0058] The slide groove 5 is connected to the entrance 3 , and a plurality of bearings 6 can be placed in the slide groove 5 . The bearings 6 in the slide groove 5 slide along the slide groove 5 to the entrance 3 , and the push rod pushes the bearings 6 at the entrance 3 into the positioning cavity 2 .

[0059] The slide groove 5 has a certain length, so a plurality of bearings 6 can be placed in the slide groove 5. The bearings 6 can move in the slide groove 5 and enter the positioning cavity 2 without interruption, thereby improving production efficiency.

[0060] In this embodiment, the push rod includes a first push rod 7 and a second push rod 8. The length direction of the chute 5 is perpendicular to the output direction of the inlet 3.

[0061] The first push rod 7 is located at one end of the slide groove 5 and the pushing direction of the first push rod 7 is opposite to the output direction of the entrance 3. The second push rod 8 is located at the other end of the slide groove 5 and the pushing direction of the second push rod 8 is the same as the length direction of the slide groove 5.

[0062] The first push rod 7 and the second push rod 8 cooperate with each other. The second push rod 8 pushes the bearing 6 in the slide groove 5 into the entrance port 3, and the first push rod 7 pushes the bearing 6 at the entrance port 3 into the positioning cavity 2 through the entrance port 3.

[0063] In this embodiment, one side of the slide groove 5 is connected to an input plane, and the bearing 6 falls into the slide groove 5 along the input plane.

[0064] Multiple bearings 6 can be placed simultaneously through the input plane, and since the length direction of the input plane is equivalent to the length direction of the chute 5, the bearings 6 can be conveniently and quickly transferred to the chute 5, thereby improving the feeding efficiency. In addition, the first push rod 7 and the second push rod 8 are used in conjunction to prevent the bearing 6 from being displaced or not being delivered to the right position.

[0065] In this embodiment, a storage chamber for placing bearings 6 is provided on the input plane, and the storage chamber extends along the length direction of the slide slot. A switch door is provided on the side of the storage chamber close to the slide slot, and a jacking structure is provided on the side of the storage chamber facing away from the slide slot. The jacking structure pushes the bearings 6 in the storage chamber into the slide slot 5.

[0066] The function of the storage chamber is to quickly set the bearing 6 in the storage chamber, and to place the bearing 6 in the extension direction of the storage chamber, so that the bearing 6 can be arranged along the side of the slide groove 5, so that it can quickly enter the slide groove 5, and under the limitation of the storage chamber, the distribution direction of the bearing 6 is more regular.

[0067] The top delivery structure pushes the bottom layer of bearing 6 into the slideway and then sends the bearing 6 into the waiting position of the slide 5 in sequence. After the divided bearing 6 is sent into the positioning mold 1 in the horizontal direction, it is only necessary to put the rotor into the bearing 6 mold; during the rotor pressing process, the material is automatically replenished to prepare for the next bearing 6 pressing.

[0068] In this embodiment, a plurality of bearing 6 limiting openings are opened on the top surface of the storage chamber, and the bearing 6 enters the storage chamber from each bearing 6 limiting opening, and each bearing 6 limiting opening is connected with a positioning rod, and the positioning rod is inserted into the hollow position of the bearings 6 (not shown in the figure) stacked on each limiting opening.

When in use, the bearing 6 is first inserted into the positioning rod, and then the positioning rod with multiple bearings 6 positioned is inserted into the storage chamber through the bearing 6 limiting opening. The positioning rod is only outside the bearing 6 limiting opening, and the bearing 6 in the storage chamber has no positioning rod to limit the position. Therefore, multiple bearings 6 can be positioned by the positioning rod, so that the bearings 6 can enter the storage chamber in sequence.

[0070] At the same time, more importantly, since the positioning rod and the chute 5 are used in combination, when the bearing 6 on the positioning rod is used up, the chute 5 can play a role in buffering ingredients to avoid shutdown, and the bearing 6 can be put back into the positioning rod at this time.

[0071] That is, the used feeder is manually taken out for material loading, thus the device can continue to produce without stopping, thereby improving production efficiency.

[0074] In this embodiment, the push-up structure includes a push plate, and the push plate is connected to a first cylinder. The first cylinder drives the push plate to push the bearing 6 in the storage chamber.

[0075] The push-feeding structure pushes the bearing 6 by connecting the push plate through the first cylinder. The push plate has a large push-out area and can quickly push multiple bearings 6 into the storage chamber at the same time.

[0076] The push plate combined with the cylinder and the first push rod 7 and the second push rod 8 can ensure that the bearing 6 does not rotate or move during the feeding process.

The positioning mold 1 is connected to a second cylinder. The positioning cavity 2 is provided with a sensor. The second cylinder is connected to the sensor. When the bearing 6 and the rotor are placed in the positioning cavity 2, the second cylinder drives the positioning mold 1 to move to the rotor pressing station.

[0078] After the rotor and the bearing 6 are assembled, the rotor is generally inserted into the bearing 6 of the positioning mold 1 by hand, and then the positioning mold 1 assembled with the bearing 6 and the rotor is transferred to the rotor pressing station, and the rotor is pressed into the bearing 6 by another pressing equipment.

[0082] A pushing component, the pushing direction of which points to the entry port 3 , is used to push the bearing 6 into the positioning cavity 2 .

[0083] Since the pushing direction of the pushing component points to the entrance 3, by placing the bearing 6 at the entrance 3, the bearing 6 can be quickly and accurately pushed into the positioning cavity 2 by the pushing component to achieve positioning of the bearing 6.

[0093] Multiple bearings 6 can be placed simultaneously through the input plane, and since the length direction of the input plane is equivalent to the length direction of the chute 5, the bearings 6 can be conveniently and quickly transferred to the chute 5, thereby improving the feeding efficiency. In addition, the first push rod 7 and the second push rod 8 are used in conjunction to prevent the bearing 6 from being displaced or not being delivered to the right position.

[0094] In this embodiment, a storage chamber for placing bearings 6 is provided on the input plane, and the storage chamber extends along the length direction of the slide slot. A switch door is provided on the side of the storage chamber close to the slide slot, and a jacking structure is provided on the side of the storage chamber facing away from the slide slot. The jacking structure pushes the bearings 6 in the storage chamber into the slide slot 5.

[0095] The function of the storage chamber is to quickly set the bearing 6 in the storage chamber, and to place the bearing 6 in the extension direction of the storage chamber, so that the bearing 6 can be arranged along the side of the slide groove 5, so that it can quickly enter the slide groove 5, and under the limitation of the storage chamber, the distribution direction of the bearing 6 is more regular.

[0096] The top delivery structure pushes the bottom layer of bearing 6 into the slideway and then sends the bearing 6 into the waiting position of the slide 5 in sequence. After the divided bearing 6 is sent into the positioning mold 1 in the horizontal direction, it is only necessary to put the rotor into the bearing 6 mold; during the rotor pressing process, the material is automatically replenished to prepare for the next bearing 6 pressing.

[0097] In this embodiment, a plurality of bearing 6 limiting openings are opened on the top surface of the storage chamber, and the bearing 6 enters the storage chamber from each bearing 6 limiting opening, and each bearing 6 limiting opening is connected with a positioning rod, and the positioning rod is inserted into the hollow position of the bearings 6 stacked on each limiting opening.

[0098] The bearing 6 limiting opening provides a position for the bearing 6 to enter. When in use, the bearing 6 is first inserted into the positioning rod, and then the positioning rod with multiple bearings 6 positioned is inserted into the storage chamber through the bearing 6 limiting opening. The positioning rod is only outside the bearing 6 limiting opening, and the bearing 6 in the storage chamber has no positioning rod to limit the position. Therefore, multiple bearings 6 can be positioned by the positioning rod, so that the bearings 6 can enter the storage chamber in sequence.

[0099] At the same time, more importantly, since the positioning rod and the chute 5 are used in combination, when the bearing 6 on the positioning rod is used up, the chute 5 can play a role in buffering ingredients to avoid shutdown, and the bearing 6 can be put back into the positioning rod at this time.

[0100] That is, the used feeder is manually taken out for material loading, thus the device can continue to produce without stopping, thereby improving production efficiency.

[0101] A bearing 6 sleeve press-fitting device according to claim 7 is characterized in that a gantry is also provided above the storage chamber, a limit plate is provided on the top of the gantry, the limit plate is provided with a snap-in notch corresponding to each positioning rod, and each positioning rod can be removably inserted into the bearing 6 limit port through the snap-in notch.

[0104] The push-feeding structure pushes the bearing 6 by connecting the push plate through the first cylinder. The push plate has a large push-out area and can quickly push multiple bearings 6 into the storage chamber at the same time.

[0105] The push plate combined with the cylinder and the first push rod 7 and the second push rod 8 can ensure that the bearing 6 does not rotate or move during the feeding process.

[0106] In this embodiment, a workbench is provided in the middle of the machine body, a press-fitting device for inserting the bearing 6 is provided on the bottom surface of the workbench, and a press-fitting part for pressing into the rotor is provided on the top surface of the workbench.

[0107] The machine body can also be provided with photoelectric switches, light curtain emergency stop buttons, barometer pressure and other equipment, so that the entire bearing 6 can be put into the press-fit device by manually controlling the bearing 6 installation machine. The positioning rod and the gantry are arranged outside the workbench to avoid difficulty in taking the positioning rod inside the workbench.

[0108] To further illustrate the use process, the following use process of the bearing 6 installation machine is now disclosed by way of example:

[0109] Preparation: Install the 608ZZ bearing 6 into the positioning rod, replace the bearing 6 mold of this model, make the bearing 6 mold correspond to the bearing 6 appearance and the rotor, adjust the photoelectric switch of the sensing rotor, check whether the light curtain emergency stop button is effective, whether the pressure of the barometer is within the qualified range, and choose to switch the rotor of this model on the touch screen.

[0110] Debugging work: After the bearing 6 mold locates the bearing 6, manually put the rotor into the upper and lower bearings 6 of the bearing 6 mold, click the touch screen to move the bearing 6 mold to the upper die tooling just below the servo electric cylinder, and ensure that the upper and lower parts are concentric, click the touch screen to manually lower the electric cylinder, press the upper and lower bearings 6 into the rotor bearing 6 position, and click the touch screen to save the height of the servo electric cylinder's descent. Observe whether the touch screen pressure is within the qualified range. If there is no abnormality, switch the screen to automatic mode.

[0111] Among them, the process of bearing 6 entering into the bearing 6 mold is: the push plate pushes the bearing 6 out of the storage chamber and transports it to the slide 5. The operator only needs to put the rotor into the bearing 6 of the bearing 6 mold. When the sensor in the mold senses the product, the mold will automatically move to the bottom of the servo electric cylinder and perform the press-fitting work. After the press-fitting is completed, the pressure will be detected within the qualified range and then automatically return to the initial position of the mold. The operator will take out the pressed rotor and put it back in.

[0112] In summary, the integrated application of automatic installation of AC and DC motor rotor bearing 6 and automatic pressing of bearing 6 is realized, which greatly reduces the production cycle and difficulty and improves the operation efficiency.

[0113] The machine integrates the functions of automatic feeding, position alignment and automatic feeding of bearing 6; the rotor automatically presses the bearing 6 simultaneously; and the rotor automatically presses the bearing 6 by using the automatic filling of the storage chamber and the waiting time of the feeding process.

[0114] The automatic installation of the AC and DC motor rotor bearing 6 and the automatic pressing device ring of the bearing 6 adopt a parallel operation mode, which solves the problems of long production cycle, difficult operation and low operation efficiency. Compared with the original production operation mode, the integrated rotor automatic sleeve bearing 6 and automatic pressing device structure are simpler, more practical, easy to operate, and the efficiency of the production process can be improved by 50%.
