[0055] As shown in the figure, Figure 1 The turntable 5 is arranged on the upper surface of the workbench 1, and the edge of the turntable 5 is uniformly distributed with a plurality of holding holes 51. In this embodiment, four holding holes 51 are arranged, as shown in the figure, Figure 4 The holding hole 51 is in communication with the outside of the turntable 5.

[0056] As shown in the figure, Figure 1 The annular pressing plate 11 is fixedly installed on the workbench 1, and the annular pressing plate 11 surrounds the turntable 5, and the annular pressing plate 11 is in sliding fit with the upper surface of the turntable 5. The annular pressing plate 11 is provided with a notch 111, and the notch 111 is in communication with one holding hole 51.

[0057] As shown in the figure, Figures 3-5 The rotating structure is used to drive the turntable 5 to rotate. The rotating structure comprises a central shaft 61, an elastic baffle 62, a sleeve 63, and a sliding pin 64.

[0058] As shown in the figure, Figure 2 The upper end of the central shaft 61 is fixedly connected with the lower end of the lifting rod 3. When the lifting rod 3 is an oil cylinder, the upper end of the central shaft 61 is fixedly connected with the piston rod of the oil cylinder. For example, the fixed connection can be achieved by welding.

[0059] As shown in the figure, Figure 1 The upper end side wall of the central shaft 61 is provided with a pressing piece 4, and the pressing piece 4 comprises a pressing rod 41 and a pressing block 42. The upper end of the pressing rod 41 is fixedly connected with the upper end side wall of the central shaft 61, and the lower end of the pressing rod 41 is fixedly installed with the pressing block 42, and the pressing block 42 corresponds to one holding hole 51.

[0060] As shown in the figure, Figure 1 The middle part of the turntable 5 is provided with an avoiding hole 52, and the lower end of the central shaft 61 extends into the inside of the workbench 1 after passing through the avoiding hole 52.

[0061] As shown in the figure, Figure 6As shown, the lower end side wall of the central shaft 61 is provided with a wavy closed sliding groove. The wavy closed sliding groove includes a plurality of inclined grooves 611 and a plurality of vertical grooves 612, the number of the inclined grooves 611 and the vertical grooves 612 is the same as the number of the holding holes 51, in this embodiment, the inclined grooves 611 and the vertical grooves 612 and the holding holes 51 are all provided with four. The inclined grooves 611 are arranged at intervals with the vertical grooves 612, the upper end of the vertical groove 612 is communicated with the upper end of the inclined groove 611 located on the left side of the vertical groove 612, and the lower end of the vertical groove 612 is communicated with the lower end of the inclined groove 611 located on the right side of the vertical groove 612.

[0062] As shown, Figure 6 As shown, the upper end of the inclined groove 611 is fixedly installed with an elastic baffle 62, and the overhanging end of the elastic baffle 62 extends into the adjacent vertical groove 612.

[0063] As shown, Figure 3 As shown, the sleeve 63 is sleeved on the central shaft 61, as shown, Figure 5 As shown, the inner wall of the sleeve 63 is fixedly installed with a sliding pin 64, the sliding pin 64 is in sliding fit with the wavy closed sliding groove, and the upper end of the sleeve 63 is fixedly connected with the rotating disc 5.

[0064] The use principle of the pressing device of this embodiment 1 is:

[0065] Because the rotating disc 5 is arranged between the upper surface of the workbench 1 and the lower surface of the annular pressing plate 11, the rotating disc 5 can only rotate horizontally. Because the rotating disc 5 is fixedly installed with the sleeve 63 and the sliding pin 64, the sleeve 63 and the sliding pin 64 can also only rotate horizontally and cannot move up and down. When the lifting rod 3 drives the central shaft 61 to move up and down, the wavy closed sliding groove on the central shaft 61 moves up and down. Because the sliding pin 64 is inserted in the wavy closed sliding groove, the sliding pin 64 will adapt to the ups and downs of the wavy closed sliding groove and rotate horizontally. Because the sliding pin 64 is installed with the sleeve 63 and the rotating disc 5, the sliding pin 64 drives the sleeve 63 to rotate horizontally, and the sleeve 63 drives the rotating disc 5 to rotate horizontally.

[0066] When the lifting rod 3 drives the central shaft 61 to move up, the central shaft 61 drives the pressing piece 4 to move up, the wavy closed sliding groove on the central shaft 61 moves up, and the sliding pin 64 slides from the communication position of the upper end of the first inclined groove 611 and the upper end of the first vertical groove 612 along the elastic baffle 62 and the first inclined groove 611. Because the height of the sliding pin 64 does not change, the sliding pin 64 appears clockwise horizontal rotation, when the sliding pin 64 slides to the communication position of the lower end of the first inclined groove 611 and the lower end of the second vertical groove 612, the sliding pin 64 has rotated 90° clockwise, and the sleeve 63 and the rotating disc 5 have also rotated 90° clockwise.

[0067] When the lifting rod 3 drives the central shaft 61 to move downward, the central shaft 61 drives the pressing piece 4 to move downward, and the undulating closed sliding groove on the central shaft 61 moves downward. The sliding pin 64 slides along the second vertical groove 612 from the position where the lower end of the first inclined groove 611 and the lower end of the second vertical groove 612 are connected. Since the height of the sliding pin 64 does not change, the sliding pin 64 does not rotate at this time. As the lifting rod 3 continues to drive the central shaft 61 to move downward, the sliding pin 64 pushes through the elastic baffle 62 into the position where the upper end of the second vertical groove 612 and the upper end of the second inclined groove 611 are connected, overcoming the elasticity of the elastic baffle 62. After the sliding pin 64 pushes through the elastic baffle 62, the elastic baffle 62 restores under the action of its own elasticity, and the elastic baffle 62 is re-blocked in the upper part of the second vertical groove 612. In this process, the sliding pin 64 still does not rotate, and the sleeve 63 and the rotating disc 5 also do not rotate.

[0068] When the lifting rod 3 drives the central shaft 61 to move upward again, the sliding pin 64 slides along the upper surface of the elastic baffle 62 into the second inclined groove 611, and then slides downward along the second inclined groove 611, so that the sliding pin 64 and the sleeve 63 and the rotating disc 5 continue to rotate clockwise by 90°. When the lifting rod 3 drives the central shaft 61 to move downward again, the sliding pin 64 and the sleeve 63 and the rotating disc 5 stop rotating, and the cycle continues.

[0069] In cooperation with the rhythm of the above-mentioned lifting of the pressing piece 4 and the rotation of the rotating disc 5, the workers can perform the following operations:

[0070] (1) When the pressing piece 4 moves downward, the bearing seat Z1 and the bearing Z2 in the corresponding containing hole 51 of the pressing piece 4 can be pressed and assembled by the pressing piece 4. The workers can simultaneously place the bearing seat Z1 and the bearing Z2 to be pressed and assembled into other containing holes 51 of the rotating disc 5, and other workers can simultaneously take away the bearing seat Z1 and the bearing Z2 that have completed the pressing assembly;

[0071] (2) When the pressing piece 4 moves upward, the rotating disc 5 drives all the bearing Z2 and the bearing seat Z1 that have not been pressed and assembled and the bearing Z2 and the bearing seat Z1 that have completed the pressing assembly to rotate clockwise by 90°, so that the bearing Z2 and the bearing seat Z1 that have completed the pressing assembly are away from the lower part of the pressing piece 4, and other bearing Z2 and bearing seat Z1 that have not been pressed and assembled enter the position below the pressing piece 4, waiting for the pressing of the pressing piece 4;

[0072] (3) When the pressing piece 4 presses downward again, the pressing piece 4 presses the bearing seat Z1 and the bearing Z2 in the corresponding containing hole 51. The workers can simultaneously take away the bearing Z2 and the bearing seat Z1 that have completed the pressing assembly, and can take away the bearing Z2 and the bearing seat Z1 that have completed the pressing assembly from the gap 111. Other workers can simultaneously place the bearing Z2 and the bearing seat Z1 to be pressed and assembled into the empty containing hole 51.

[0073] (4) Repeat the above steps, so as to realize continuous production.

[0074] From the above process, it can be seen that in the press-fitting device of the present embodiment 1, the pressing assembly of the bearing Z2 and the bearing seat Z1, the placing of the bearing Z2 and the bearing seat Z1 to be pressed and assembled, and the taking away of the bearing Z2 and the bearing seat Z1 which have completed the pressing assembly can be carried out at the same time, which is beneficial to improve the processing efficiency.

[0075] Embodiment 2:

[0076] The present embodiment 2 is further improved on the basis of the embodiment 1:

[0077] As shown in Figures 7-17 , the press-fitting device of the bearing and the bearing seat of the present embodiment 2 further comprises a bearing seat storage cylinder 7, a bearing storage cylinder 8, a discharging structure, and a shielding structure.

[0078] As shown in Figure 7 , 8 , 10, 15, 16, the four holding holes 51 in the embodiment 1 correspond to the bearing seat storage cylinder 7, the bearing storage cylinder 8, the pressing piece 4, and the discharging structure in turn respectively.

[0079] As shown in Figure 13 , the bearing seats Z1 are vertically stacked in the bearing seat storage cylinder 7, and as shown in Figure 11 , the bearings Z2 are vertically stacked in the bearing storage cylinder 8. Both the bearing seat storage cylinder 7 and the bearing storage cylinder 8 adopt a cylinder structure. As shown in Figure 8 , the upper end of the cylinder structure is fixedly connected with the base plate 21 in the support 2. The lower end of the cylinder structure is provided with the shielding structure. When the lifting rod 3 drives the central shaft 61 to move upward, the shielding structure prevents the bearing seat Z1 or the bearing Z2 in the cylinder structure from falling. When the lifting rod 3 drives the central shaft 61 to move downward, the shielding structure releases the lowermost bearing seat Z1 or the lowermost bearing Z2 in the cylinder structure.

[0080] As shown in Figure 9 , the shielding structure comprises a support seat 101, a connecting rod 102, a connecting pin 103, a rotating seat 104, a tilting rod 105, a first pin shaft 106, a second pin shaft 107, a first plate body 108, and a second plate body 109.

[0081] As shown in Figure 9 , the support seat 101 is fixedly installed on the upper end side wall of the central shaft 61, two connecting rods 102 are rotationally connected with the support seat 101, the lower ends of the two connecting rods 102 are away from each other, and the lower ends of the two connecting rods 102 are both rotationally connected with the connecting pin 103.

[0082] As shown in Figures 11-14As shown, the lower end of the barrel structure is symmetrically provided with two rotating seats 104, two lever rods 105, two first pin shafts 106, two second pin shafts 107, two first plate bodies 108, and two second plate bodies 109. Figure 9 As shown, the rotating seat 104 is fixedly connected with the lower end outer wall of the barrel structure, the rotating seat 104 is rotationally connected with the middle part of the lever rod 105, the lower end of the lever rod 105 is provided with a first long hole 1051, the upper end of the lever rod 105 is provided with a second long hole 1052, the first pin shaft 106 is arranged in the first long hole 1051, the second pin shaft 107 is arranged in the second long hole 1052, the first pin shaft 106 is fixedly connected with the first plate body 108, the second pin shaft 107 is fixedly connected with the second plate body 109, and the first plate body 108 and the second plate body 109 are both horizontally inserted and matched with the side wall of the barrel structure.

[0083] As shown, Figure 13 For the barrel structure of the bearing seat storage barrel 7, a bearing seat Z1 is arranged between the first plate body 108 and the second plate body 109. As shown, Figure 11 For the barrel structure of the bearing storage barrel 8, a bearing Z2 is arranged between the first plate body 108 and the second plate body 109.

[0084] As shown, Figures 14 to 13 For the barrel structure of the bearing seat storage barrel 7, when the center shaft 61 is lifted up by the lifting rod 3, the center shaft 61 lifts up the support seat 101, the distance between the lower ends of the two connecting rods 102 is reduced, the distance between the two connecting pins 103 is reduced, and the distance between the two first plate bodies 108 is reduced. At this time, the first plate body 108 not only inserts into the inner cavity of the barrel structure, but also blocks below the lowermost bearing seat Z1, preventing the bearing seat Z1 from falling. When the distance between the two first plate bodies 108 is reduced, the upper ends of the two lever rods 105 are away from each other, the second long hole 1052 pushes the second pin shaft 107, the second pin shaft 107 drives the second plate body 109, so that the second plate body 109 gradually withdraws from the inner cavity of the barrel structure. At this time, the second last bearing seat Z1 falls on the last bearing seat Z1. For the bearing storage barrel 8, the same is true, see Figures 12 to 11 the state change.

[0085] As shown, Figures 13 to 14When the lifting rod 3 drives the central shaft 61 to move downward, the central shaft 61 drives the support base 101 to move downward, the distance between the lower ends of the two connecting rods 102 increases, the distance between the two connecting pins 103 increases, and the distance between the two first plate bodies 108 increases. At this time, the first plate body 108 gradually exits the inner cavity of the barrel structure. At the same time, the upper ends of the two rocker bars 105 are close to each other, the second long hole 1052 pushes the second pin shaft 107, the second pin shaft 107 drives the second plate body 109, so that the two second plate bodies 109 are close to each other, and the second plate body 109 is inserted into the inner cavity of the barrel structure. The second plate body 109 is longer than the first plate body 108, and the second plate body 109 is inserted between the last bearing seat Z1 and the second last bearing seat Z1 first. The second last bearing seat Z1 can be blocked by the second plate body 109 to prevent the second last bearing seat Z1 from falling. Then, the first plate body 108 moves away from the lower surface of the last bearing seat Z1, and the last bearing seat Z1 is no longer blocked by the first plate body 108, so that the last bearing seat Z1 can fall into the containing hole 51. The same is true for the bearing storage barrel 8. See Figures 11 to 12 the state change.

[0086] When the lifting rod 3 drives the central shaft 61 to move upward again, the two first plate bodies 108 are close to each other, the two second plate bodies 109 are far away from each other, the second last bearing seat Z1 originally falls on the first plate body 108 to become the last bearing seat Z1, and the third last bearing seat Z1 becomes the new second last bearing seat Z1, and so on. The lifting rod 3 is lowered each time, and only one bearing seat Z1 is allowed to be released. The same is true for the bearing Z2.

[0087] As shown in Figure 7 , the unloading structure is used to unload the bearing Z2 and the bearing seat Z1 on the workbench 1 which have been completed. The notch 111 on the annular pressing plate 11 corresponds to the unloading structure.

[0088] As shown in Figure 16 , the unloading structure of the second embodiment is shown. The unloading structure includes an air cylinder 91, an adjusting rod 92, and a piston 93.

[0089] As shown in Figure 16 , the upper end of the air cylinder 91 is fixedly connected with the base plate 21 in the support 2, the side wall of the air cylinder 91 is provided with a movable hole 911, one end of the adjusting rod 92 is fixedly connected with the upper end of the central shaft 61, the other end of the adjusting rod 92 extends into the inside of the air cylinder 91 after passing through the movable hole 911, and the end of the adjusting rod 92 in the air cylinder 91 is fixedly installed with the piston 93. The piston 93 is vertically and slidingly connected with the air cylinder 91, as shown in Figure 17 , the lower end of the air cylinder 91 is provided with a gas port 912, and the gas port 912 is inclined to the containing hole 51.

[0090] When the lifting rod 3 drives the central shaft 61 to move upwards, the central shaft 61 drives the adjusting rod 92 to move upwards, and the adjusting rod 92 drives the piston 93 to move upwards. At this time, the outside air is sucked into the lower part of the air cylinder 91 from the air port 912.

[0091] When the lifting rod 3 drives the central shaft 61 to move downwards, the central shaft 61 drives the adjusting rod 92 to move downwards, and the adjusting rod 92 drives the piston 93 to move downwards. At this time, the piston 93 pushes the air in the lower part of the air cylinder 91 out from the air port 912, and the bearing Z2 and the bearing seat Z1 that have been completed with the pressing assembly are blown away from the gap 111 by the air flow. The unloading is realized.

[0092] In the pressing device of the second embodiment, the worker can perform the following operations in the rhythm of the pressing piece 4 lifting and the rotating disc 5 rotating according to the first embodiment:

[0093] (1) When the pressing piece 4 moves downwards, the pressing piece 4 presses the bearing seat Z1 and the bearing Z2 in the corresponding holding hole 51, at the same time, the unloading structure blows away the bearing Z2 and the bearing seat Z1 in the corresponding holding hole 51 that have been completed with the pressing assembly, the last bearing seat Z1 in the bearing seat storage cylinder 7 falls into the corresponding holding hole 51, the last bearing Z2 in the bearing storage cylinder 8 falls into the corresponding holding hole 51, and the bearing Z2 enters the holding hole 51 that has placed the bearing seat Z1 in the last time when the pressing piece 4 moves downwards;

[0094] (2) When the pressing piece 4 moves upwards, the rotating disc 5 drives the bearing Z2 and the bearing seat Z1 in the holding hole 51 to rotate 90° clockwise, the holding hole 51 that has just placed the bearing seat Z1 in the step (1) rotates to the lower part of the bearing storage cylinder 8, the holding hole 51 that has placed the bearing Z2 and the bearing seat Z1 in the step (1) rotates to the lower part of the pressing piece 4, and the bearing Z2 and the bearing seat Z1 that have been completed with the pressing assembly in the step (1) rotate to the lower part of the unloading structure;

[0095] (3) When the pressing piece 4 moves downwards again, the pressing piece 4 presses the bearing seat Z1 and the bearing Z2 in the corresponding holding hole 51, at the same time, the unloading structure blows away the bearing Z2 and the bearing seat Z1 in the corresponding holding hole 51 that have been completed with the pressing assembly, the new last bearing seat Z1 in the bearing seat storage cylinder 7 falls into the corresponding holding hole 51, the new last bearing Z2 in the bearing storage cylinder 8 falls into the corresponding holding hole 51, and the bearing Z2 enters the holding hole 51 that has placed the bearing seat Z1 in the step (1);

[0096] (4) The above steps are repeated, and the continuous production is realized.

[0097] Through the above process, it is known that the bearing Z2 and the bearing seat Z1 do not need to be placed into the containing hole 51 manually by workers, and the bearing Z2 and the bearing Z2 that have completed the pressing assembly also do not need to be taken away manually by workers, mechanical operation is realized, and the labor intensity of workers is reduced.

[0098] Unexpectedly, because the bearing seat Z1 is stored in the bearing seat storage cylinder 7, and the bearing Z2 is stored in the bearing storage cylinder 7, the occupation of horizontal space of the device is reduced, vertical space is fully occupied, the occupation of the workshop site is saved, and site cost is saved.

[0099] In addition, it is convenient to store the bearing seat Z1 into the bearing seat storage cylinder 7 and to store the bearing Z2 into the bearing storage cylinder 8, the bearing seat Z1 is simply stacked into the bearing seat storage cylinder 7, and the bearing Z2 is simply stacked into the bearing storage cylinder 8, material supplementing is convenient, the pressing assembly operation is not delayed, and the material supplementing efficiency is improved.

[0100] In addition, the shielding structures on the bearing seat storage cylinder 7 and the bearing storage cylinder 8 can ensure that only the last bearing Z2 or the last bearing seat Z1 falls each time, and prevent the second last bearing Z2 or the second last bearing seat Z1 from following, so as to ensure the accuracy of pressing assembly of one bearing seat Z1 and one bearing Z2, and the assembly efficiency of the bearing Z2 and the bearing seat Z1 is improved.

[0101] Further, the actions of the shielding structure and the discharging structure are driven by the central shaft 61, so that the central shaft 61 is driven by only the lifting rod 3, a power source is saved, and cost is reduced.

[0102] Embodiment 3

[0103] The embodiment 3 is further improved on the basis of the embodiment 2.

[0104] As shown in Figure 18 , the embodiment 3 gives another discharging structure. The discharging structure includes a spray head 94, a spray pipe 95, an air tank 96, an electromagnetic valve 97, a reflective photoelectric sensor 98, a reflecting plate 99, a controller 913, and a power supply 910.

[0105] As shown in Figure 18 , the spray pipe 95 is fixedly installed on the base plate 21, and the lower end of the spray pipe 95 is fixedly installed with the spray head 94.

[0106] As shown in Figure 18 , the air tank 96 stores compressed air, and the outlet of the air tank 96 is connected with the upper end of the spray pipe 95 through an air pipe.

[0107] As shown in Figure 18As shown, a solenoid valve 97 is installed at the outlet of the air tank 96. When the solenoid valve 97 is open, the compressed air in the air tank 96 can be ejected from the nozzle 94 through the air pipe and the nozzle 95. When the solenoid valve 97 is closed, the compressed air in the air tank 96 stops flowing out.

[0108] like Figure 18 As shown, a reflective photoelectric sensor 98 is fixedly installed on the lower side wall of the nozzle 95. The reflective photoelectric sensor 98 is a prior art technology. The reflective photoelectric sensor 98 integrates a transmitter and a receiver, and receives the light reflected back by the detected object through the receiver.

[0109] like Figure 18 As shown, a reflector plate 99 is fixedly installed on the upper side wall of the central shaft 61.

[0110] like Figure 18 As shown, the controller 913 and the power supply 910 are both mounted on the base plate 21. The reflective photoelectric sensor 98 is electrically connected to the controller 913, and the controller 913 is electrically connected to the solenoid valve 97. The power supply 910 is used to supply power to the reflective photoelectric sensor 98, the controller 913, and the solenoid valve 97.

[0111] When the lifting rod 3 moves the central shaft 61 downward, the central shaft 61 moves the reflector 99 downward. When the reflector 99 moves to the lowest position, the light emitted by the emitter of the reflective photoelectric sensor 98 is reflected into the receiver by the reflector 99. At this time, the reflective photoelectric sensor 98 transmits the signal to the controller 913. The controller 913 controls the solenoid valve 97 to open. At this time, the compressed air in the air tank 96 can be sprayed out from the nozzle 94 through the air pipe and the nozzle 95. The compressed air sprayed out from the nozzle 94 blows away the bearing Z2 and bearing seat Z1 that have completed the pressing, thus completing the unloading.

[0112] When the lifting rod 3 moves the central shaft 61 upward, the central shaft 61 moves the reflector 99 upward. The light emitted by the transmitter in the reflective photoelectric sensor 98 is not reflected back to the receiver. At this time, the controller 913 controls the solenoid valve 97 to close.

[0113] As can be seen from the above process, the unloading structure of this embodiment 3 is the same as that of embodiment 2. Both can be driven by the central shaft 61 and can blow away the bearing Z2 and bearing seat Z1 that have been pressed. However, this embodiment 3 uses compressed air to blow away the bearing Z2 and bearing seat Z1 that have been pressed, so the blowing power is greater and it can blow away the bearing Z2 and bearing seat Z1 that have been pressed more reliably and faster.

[0114] Example 4:

[0115] This embodiment 4 is an improvement upon embodiment 2:

[0116] likeFigure 19 In this embodiment 4, the elastic baffle 62 is replaced by a hard baffle 65, one end of the hard baffle 65 is rotatably connected with the upper end of the lower groove wall of the inclined groove 611 through a rotating shaft 66, the lower surface of the hard baffle 65 is fixedly connected with the upper end of a spring 67, the lower end of the spring 67 is fixedly connected with the groove wall of the vertical groove 612, the other end of the hard baffle 65 is suspended, and the suspended end of the hard baffle 65 is inserted into the vertical groove 612.

[0117] When the lifting rod 3 drives the central shaft 61 to move downward, the sliding pin 64 slides upward in the first vertical groove 612, the sliding pin 64 can push the hard baffle 65 upward against the elastic force of the spring 67, and the hard baffle 65 rotates counterclockwise around the rotating shaft 66; when the sliding pin 64 moves upward to the position where the first vertical groove 612 is connected with the upper end of the first inclined groove 611, the sliding pin 64 is separated from the hard baffle 65, and the hard baffle 65 falls back to the upper end of the first inclined groove 611 under the elastic force of the spring 67, at this time, the hard baffle 65 is blocked by the lower groove wall of the first inclined groove 611, and the hard baffle 65 cannot continue to rotate downward around the rotating shaft 66.

[0118] When the lifting rod 3 drives the central shaft 61 to move upward, because the hard baffle 65 blocks the first vertical groove 612, the sliding pin 64 can slide along the surface of the hard baffle 65 to the lower groove wall of the first inclined groove 611, and then slide along the lower groove wall of the first inclined groove 611 to the position where the lower end of the first inclined groove 611 is connected with the lower end of the second vertical groove 612.

[0119] When the lifting rod 3 drives the central shaft 61 to move downward again, the sliding pin 64 slides upward in the second vertical groove 612. In this way, the sliding of the sliding pin 64 in the up-and-down closed sliding groove is realized.

[0120] The hard baffle 65 of this embodiment 4 and the elastic baffle 62 of embodiment 2 have the same effect, on the one hand, when the sliding pin 64 moves upward in the vertical groove 612 as the central shaft 61 moves downward, the hard baffle 65 and the elastic baffle 62 will not hinder the sliding pin 64 to move to the position where the upper end of the vertical groove 612 is connected with the upper end of the inclined groove 611; on the other hand, when the central shaft 61 moves upward, the hard baffle 65 and the elastic baffle 62 prevent the sliding pin 64 from entering the vertical groove 612 again, but ensure that the sliding pin 64 slides along the inclined groove 611 to the lower end of the other vertical groove 612. Thus, it can be ensured that the sliding pin 64, the sleeve 63 and the rotating disc 5 can rotate clockwise by 90° when the central shaft 61 moves upward, and then the reliability of the press-fitting device is ensured.

[0121] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.
