Description

Technical Field

[0001] The present invention relates to the technical field of press-fitting manufacturing, and particularly to a heating assembly system. Background Art

[0002] During the installation process of mechanical structures, there are fitting methods such as clearance fit and interference fit. Interference fit means that the diameter of the shaft is larger and the diameter of the hole is smaller. By assembly, the hole diameter becomes larger, so as to generate a certain degree of clamping force on the shaft after assembly, and the relative position between the shaft and the hole is fixed.

[0003] For interference fit, most of the time, operators need to use tools such as hammers to drive the shaft into the hole. However, when the interference amount is large, that is, the diameter of the shaft is too large and the diameter of the hole is too small, it is difficult to achieve the assembly of the shaft and the hole by manual driving. Moreover, the shaft or hole is easily damaged by the driving method. Therefore, at present, for the assembly of shafts and holes with a large interference amount, it is mostly necessary to first heat the hole to relatively increase the hole diameter or improve the deformation degree of the hole, and then press the shaft in. By this method, the shaft can be more smoothly pressed into the hole.

[0004] However, at present, there is no systematic equipment for this method to operate, so that the operation process is relatively scattered. When the shaft needs to be quickly installed into the hole after heating, the hole often shrinks in advance due to the heat loss of the workpiece during the transfer process, which not only greatly affects the operation efficiency, but also reduces the yield.

[0005] Therefore, there is an urgent need to provide a heating assembly system to solve the problems existing in the prior art to a certain extent. Summary of the Invention

[0017] Compared with the prior art, the heating and assembling system provided by the present invention has the following advantages:

[0018] The heating and assembling system provided by the present invention includes a turntable device, a heating device, a press-fitting device, and a cooling device; the turntable device is provided with a first positioning part and a second positioning part, and an operation station, a heating station, a press-fitting station, and a cooling station are sequentially formed along the circumferential direction of the turntable device; the heating device is arranged corresponding to the second positioning part at the heating station, and the cooling device is arranged corresponding to the cooling station; the press-fitting device is arranged corresponding to the first positioning part at the press-fitting station, and the press-fitting device can clamp the workpiece in the first positioning part and transfer it into the second positioning part, and press-fit it with the workpiece in the second positioning part; the turntable device can drive the first positioning part and the second positioning part to sequentially pass through the heating station, the press-fitting station, and the cooling station from the operation station, and rotate back to the operation station.

[0019] It can be analyzed from this that the first positioning part and the second positioning part provided on the turntable device can carry the parts to be press-fitted and the parts to be heated.

[0038] As shown Figure 1 in the figure, the present invention provides a heating and assembling system, including a turntable device 1, a heating device 2, a pressing device 3 and a cooling device 4; the turntable device 1 is provided with a first positioning portion 105 and a second positioning portion 106, and an operating station, a heating station, a pressing station and a cooling station are sequentially formed along the circumferential direction of the turntable device 1; the heating device 2 is arranged corresponding to the second positioning portion 106 at the heating station, and the cooling device 4 is arranged corresponding to the cooling station; the pressing device 3 is arranged corresponding to the first positioning portion 105 at the pressing station, and the pressing device 3 can clamp the workpiece in the first positioning portion 105 and transfer it into the second positioning portion 106, and press it with the workpiece in the second positioning portion 106; the turntable device 1 can drive the first positioning portion 105 and the second positioning portion 106 to sequentially pass through the heating station, the pressing station and the cooling station from the operating station, and rotate back to the operating station.

[0039] Compared with the prior art, the heating and assembling system provided by the present invention has the following advantages:

[0040] For the heating and assembling system provided by the present invention, the first positioning portion 105 and the second positioning portion 106 provided on the turntable device 1 can carry the parts to be pressed and the parts to be heated. Since the turntable device 1 in the present application can rotate, an operating station, a heating station, a pressing station and a cooling station are sequentially formed along the circumferential direction of the turntable device 1, and the heating device 2 is arranged corresponding to the second positioning portion 106 at the heating station, and the pressing device 3 is arranged corresponding to the first positioning portion 105 at the pressing station, and the cooling device 4 is arranged corresponding to the cooling station. Therefore, the first positioning portion 105 in the present application carries the parts to be pressed, and the second positioning portion 106 carries the parts to be heated.

[0041] When assembling operations need to be performed on the parts to be pressed and the parts to be heated, the operator loads the parts to be pressed into the first positioning portion 105 and the parts to be heated into the second positioning portion 106 at the operating station. After that, the turntable device 1 rotates to move the first positioning portion 105 and the second positioning portion 106 to the heating station. Since the heating device 2 is arranged corresponding to the second positioning portion 106 at the heating station, only the parts to be heated can be heated.

[0042] After heating is completed, the turntable device 1 rotates to the pressing station. Since the pressing device 3 is arranged corresponding to the first positioning portion 105 at the pressing station, the pressing device 3 can transfer the parts to be pressed in the first positioning portion 105 into the second positioning portion 106 and press them with the parts to be heated that have been heated in the second positioning portion 106.

[0043] After the press-fitting is completed, the turntable device 1 rotates to the cooling station, and the cooling device 4 cools the workpiece completed with press-fitting in the second positioning portion 106. After the cooling is completed, the turntable device 1 rotates again to return the first positioning portion 105 and the second positioning portion 106 to the operation station. The operator takes out the press-fitted workpiece and performs the next operation on the workpiece to be press-fitted and the workpiece to be heated in the corresponding manner again.

[0044] Through the heating and assembling system provided by the present application, the automatic operations of workpiece heating, workpiece press-fitting, and workpiece cooling during the assembling process of two workpieces with a large interference amount can be automatically completed, and can be quickly completed within one cycle, avoiding the problem that the workpiece to be heated fails to be assembled with the workpiece to be press-fitted for a long time after heating, resulting in heat dissipation and assembly failure.

[0045] As Figure 1 shown, in practical applications, the heating and assembling system provided by the present application further includes a mounting bench 5. A working cavity is formed on the mounting bench 5. The turntable device 1, the heating device 2, the press-fitting device 3, and the cooling device 4 are all arranged in the working cavity; a control device 501 is further provided outside the working cavity, and the control device 501 is communicatively connected to the turntable device 1, the heating device 2, the press-fitting device 3, and the cooling device 4 to control the actions of the turntable device 1, the heating device 2, the press-fitting device 3, and the cooling device 4.

[0046] It can be understood that the control device 501 in the present application includes a controller and an operator. The display is arranged on the mounting bench 5. And since the workpiece to be heated and the workpiece to be press-fitted in the present application are both manually loaded and unloaded at the operation station, therefore, the display provided by the present application is located above the operation station, so as to facilitate the operator to observe the operation.

[0047] The controller in the present application can be a terminal controller such as a single-chip microcomputer, a PLC, or a PC, and is integrated on the mounting bench 5, communicatively connected to the driving mechanism 102 of the turntable device 1, the first driving member 204, the second driving member 206, and the heat supply component 202 of the heating device 2, communicatively connected to the air supply mechanism of the cooling device 4, and communicatively connected to the driving component 301 and the third driving member 306 of the press-fitting device 3, so as to realize the automatic control of the actions of each device structure.

[0048] It should be supplemented and explained here that since the heating problems and press-fitting forces of different workpieces are different during the press-fitting process, and the heating and assembling system provided by the present application can assemble a variety of workpieces, but the process parameters need to be switched. Therefore, preferably, as Figure 1As shown, a code scanning device 502 is further provided on the installation bench 5. Correspondingly, identification codes are attached to both the workpiece to be heated and the workpiece to be press-fitted in this application. The code scanning device 502 can identify the workpiece to be heated and the workpiece to be press-fitted with corresponding process parameters, thereby avoiding to a certain extent the problem of workpiece or equipment damage caused by the mismatch between the workpiece to be heated and the workpiece to be press-fitted during transportation and their corresponding process parameters.

[0049] Optionally, as Figure 1 Combined with Figure 2 As shown, the turntable device 1 in this application includes a turntable main body 101 and a driving mechanism 102; a rotating shaft is formed on one side of the turntable main body 101 facing away from the first positioning portion 105 and the second positioning portion 106, and the rotating shaft is connected to the output shaft of the driving mechanism 102, and the driving mechanism 102 can drive the turntable main body 101 to rotate.

[0050] In this application, the driving mechanism 102 can be a driving motor, and the output shaft of the driving motor can be directly connected to the rotating shaft of the turntable main body 101. However, since the diameter of the turntable main body 101 in this application is relatively large, the inertia of the turntable main body 101 is relatively large when it rotates, and a relatively large torque of the driving motor is required. Therefore, as Figure 2 As shown, the turntable device 1 in this application further includes a transmission mechanism 103, and the transmission mechanism 103 can adopt a conveyor belt structure, that is, it has a driving wheel, and the driving wheel is connected to the output shaft of the driving motor, and multiple driven wheels. The multiple driven wheels tension the transmission belt, and one of the driven wheels is connected to the rotating shaft of the turntable main body 101, so as to realize the rotation of the turntable main body 101 and avoid to a certain extent the problem of damage to the driving motor caused by the inertia of the turntable main body 101.

[0051] It can be understood that the transmission mechanism 103 in this application can also adopt a combination of multiple gears or sprockets and chains. By the combination of gears and chain sprockets, while reducing the influence of the inertia of the turntable main body 101 on the driving motor, the accuracy of the stop position of the turntable main body 101 can be further improved.

[0052] It should be supplemented and explained here that the first positioning portion 105 and the second positioning portion 106 provided on the turntable main body 101 in this application are correspondingly arranged, so as to shorten the distance for transferring the workpiece to be press-fitted in the first positioning portion 105 to the second positioning portion 106, and further reduce the heat dissipation of the workpiece to be heated after heating is completed, improving the operation efficiency and operation success rate.

[0053] It should be further noted here that the number of the first positioning parts 105 and the second positioning parts 106 on the turntable body 101 in this application is multiple. Preferably, since operation stations, heating stations, press-fitting stations, and cooling stations are formed in this application, the number of the first positioning parts 105 and the second positioning parts 106 on the turntable body 101 is four. The four first positioning parts 105 are arranged at equal intervals along the circumferential direction of the turntable body 101, and the four second positioning parts 106 are arranged corresponding to the four first positioning parts 105, so as to enable flow operation corresponding to the four stations.

[0054] Since the parts to be press-fitted in the first positioning part 105 are finally press-fitted with the parts to be heated in the second positioning part 106, further preferably, as Figure 2 shown, in this application, the second positioning part 106 is closer to the edge of the turntable body 101, so that it is convenient for the operator to take out the press-fitted workpiece at the operation station.

[0055] The number of the above-mentioned first positioning parts 105 and second positioning parts 106 being four is only one preferred implementation manner. The number of the first positioning parts 105 and the second positioning parts 106 can also be six or eight, as long as the first positioning parts 105 and the second positioning parts 106 are arranged in one-to-one correspondence.

[0056] It should be noted here that a limiting block 104 is further provided on one side of the turntable body 101 facing the driving mechanism 102 in this application, and the limiting block 104 can limit the rotation angle of the turntable body 101, that is, when the number of the first positioning parts 105 and the second positioning parts 106 is four, the limiting block 104 can control the turntable body to rotate 90° at a time.

[0057] Optionally, as Figure 2 shown, a detection component 107 is provided on the turntable body 101 in this application. The detection component 107 is arranged corresponding to the first positioning part 105 and the second positioning part 106, and the detection component 107 can detect the position of the part to be press-fitted relative to the first positioning part 105 and the position of the part to be heated relative to the second positioning part 106.

[0058] The detection component 107 in this application can be a photoelectric sensor. Through the photoelectric sensor, it can be checked whether there are parts to be press-fitted and parts to be heated on the first positioning part 105 and the second positioning part 106, so as to avoid misoperation of the overall equipment.

[0059] A detection component 107 is provided on the turntable body 101. When located at the operating station, the detection component 107 can detect whether the operator has correspondingly loaded the parts to be pressed and the parts to be heated into the first positioning portion 105 and the second positioning portion 106. When it is detected that there are parts to be pressed and parts to be heated, the turntable body 101 rotates to the heating station to heat the parts to be heated.

[0060] When the heating is completed, the turntable body 101 rotates to the pressing station, the pressing device 3 takes out the workpiece to be pressed and transfers it to the second positioning part 106. When the detection component 107 detects that the workpiece to be pressed in the first positioning part 105 is taken out, the pressing device 3 can perform the pressing action. If the workpiece to be pressed in the first positioning part 105 is detected, it proves that the pressing device 3 has not successfully taken out the workpiece to be pressed. The controller controls the pressing device 3 to clamp the workpiece to be pressed again until the detection component 107 detects that there is no workpiece in the first positioning part 105.

[0061] Therefore, the detection component 107 can avoid the missing of the parts to be heated and the parts to be pressed to a certain extent, and can also avoid the problem of clamping failure of the parts to be pressed.

[0062] Alternatively, if Figure 2 As shown, the heating device 2 in the present application includes a heating mechanism and a clamping mechanism; the clamping mechanism includes a pressing assembly and a lifting assembly, the second positioning portion 106 is formed with a first through hole, the first through hole extends in the vertical direction, one end of the lifting assembly can pass through the first through hole and abut against one side of the part to be heated in the second positioning portion 106, and lift the part to be heated; one end of the pressing assembly can move toward the direction approaching the second positioning portion 106, and abut against the side of the part to be heated away from the lifting assembly, and cooperate with the lifting assembly to move the part to be heated to the position of the heating mechanism for heating.

[0063] Since the position of the heating mechanism in the present application is fixed and cannot be moved, the clamping mechanism set up in the present application, and the clamping mechanism includes a pressing component and a lifting component, which can stably clamp the workpiece to be heated in the second positioning portion 106 and move it to the heat source of the heating mechanism for heating.

[0064] To ensure the stable movement of the heated component, the pressing assembly in the present application includes a first driving member 204 and a first pressing plate 205, and as shown in FIG. Figure 2 As shown, preferably, in the present application, the first driving member 204 is a first cylinder, the lifting assembly includes a second driving member 206 and a second pressure plate, and the second driving member 206 is a second cylinder, the first cylinder and the second cylinder are both telescoped in the vertical direction, and the axis of the first cylinder and the axis of the second cylinder are collinear.

[0065] When heating is required for the workpiece to be heated, the pressing assembly first operates. The first cylinder drives the first pressing plate 205 to move in the direction approaching the second positioning portion 106. When the first pressing plate 205 contacts the workpiece to be heated, the second cylinder operates. Since the first perforation is provided on the second positioning portion 106, the second pressing plate can pass through the first perforation under the push of the second cylinder and abut against the workpiece to be heated within the second positioning portion 106, so that the workpiece to be heated can be stably clamped by the first pressing plate 205 and the second pressing plate.

[0066] After that, the second cylinder continues to extend and the first driving member 204 contracts, so that the workpiece to be heated can be moved in the direction approaching the heating mechanism, and then after the workpiece to be heated is moved in place, heating of the workpiece to be heated can be achieved.

[0067] Optionally, as Figure 2 shown, the heating mechanism in the present application includes a heating head 201, a heat supply assembly 202, and a cooling water tank 203; one end of the heating head 201 is connected to the heat supply assembly 202, and the heat supply assembly 202 provides heat transmission for the heating head 201.

The cooling water tank 203 provides circulating cooling water through a circulation water pipe, and the heat supply assembly 202 is cooled by arranging the circulation water pipe in the heat supply assembly 202.

[0070] When heating is required for the workpiece to be heated, the workpiece to be heated is lifted by the clamping of the first pressing plate 205 and the second pressing plate. When the heating head 201 passes through the second perforation and enters the hole of the workpiece to be heated, the first driving member 204 and the second driving member 206 stop operating, and the heat supply assembly 202 supplies heat to the heating head 201, so that the heating head 201 generates heat to heat the workpiece to be heated.

[0071] After the heating is completed, the first pressure plate 205 and the second pressure plate clamp the piece to be heated and move downwards to fall back into the second positioning portion 106. Then, the first pressure plate 205 and the second pressure plate return to their original positions, completing the heating operation.

[0074] In this application, the driving assembly 301 is arranged in the vertical direction, so as to be able to drive the press head 302 to reciprocate in the vertical direction. And the slideway 304 in this application extends in the horizontal direction, so as to be able to realize the movement of the driving assembly 301 driving the press head 302 in the horizontal direction, and further realize the function of moving the piece to be press-fitted from the first positioning portion 105 to the second positioning portion 106.

[0075] The clamping portion in this application is arranged in the press head 302, and the clamping end of the clamping portion can penetrate through the side of the press head 302 in contact with the piece to be press-fitted to clamp the piece to be press-fitted.

[0076] It should be noted here that the piece to be press-fitted in this application is a shaft to be assembled with a hole. Therefore, the clamping portion in this application can adopt structures such as a gripper to grab the shaft for movement, or can also adopt a clamping portion opened on the shaft, that is, a positioning groove is opened, so that after the clamping portion extends into the positioning groove and opens, the transfer of the shaft is realized through the tension force.

[0077] It should be further noted here that, preferably, as Figure 3 shown, the driving assembly 301 in this application includes a servo motor and a lead screw. The lead screw extends in the vertical direction, the output end of the servo motor is connected to the lead screw, and the press head 302 is in threaded cooperation with the lead screw. When the servo motor drives the lead screw to rotate, the press head 302 can reciprocate on the lead screw, so as to be able to realize the clamping and press-fitting of the piece to be press-fitted.

Among them, the temperature sensor 503 corresponding to the heating head 201 can detect the state of the temperature at which the heating head 201 heats the parts. When the heating temperature of the workpiece reaches the set temperature, the workpiece to be heated is separated from the heating head 201, and the turntable main body 101 rotates to the press-fitting station to prepare for the press-fitting operation. The temperature sensor 503 corresponding to the pressure head 302 can detect whether the temperature of the workpiece to be heated moving to the press-fitting station reaches the press-fitting temperature, so as to judge whether the press-fitting operation can be carried out. If the temperature does not meet the standard, the workpiece is directly rotated to the cooling station for cooling through the turntable main body 101 and then rotated to the operation station to take out the workpiece.
