Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] like Figures 1 to 12 As shown, the present invention provides a press-fitting device for pressing a part 100 into a workpiece 200. For example, if part 100 is a dust seal and workpiece 200 is a motor shaft, the press-fitting device is used to press the dust seal into the motor shaft. The press-fitting device includes a press-fitting station 1, a clamping unit 2, a drive unit 3, and a buffer unit 4. It may also include a feeding unit 5, a supply unit 6, a transfer unit 7, and a discharge unit 8.

[0025] Further references Figures 3 to 5The press-fitting station 1 includes a press-fitting position 111, which is located below the clamping unit 2, and the workpiece 200 to be processed can be positioned at the press-fitting position 111. Specifically, the press-fitting station 1 may include a rotating seat 12 and at least three positioning members 14 installed on the rotating seat 12. The positioning members 14 can be used to position the workpiece 200 to be processed so that the workpiece 200 to be processed remains fixed equivalent to the rotating seat 12. The rotating seat 12 can be a disc-shaped structure, and the rotating seat 12 can rotate around its center of circle. When a positioning member 14 rotates to the point directly below the clamping unit 2, the position of the positioning member 14 is the press-fitting position 111, and the remaining positioning members 14 can be located at the finished product position 13 where the pressing process is completed or the installation position 15 of the workpiece 200 to be processed.

[0026] In this embodiment, three positioning members 14 may be provided on the rotating seat 12, and the three positioning members 14 are distributed in a circular array around the center of the rotating seat 12. After the workpiece 200 to be processed in one positioning member 14 is press-fitted with the part 100 at the press-fitting position 111, the rotating seat 12 rotates so that the next positioning member 14 moves to the press-fitting position 111; at this time, the workpiece after the press-fitting part 100 is positioned at the finished product position 13 after the rotating seat 12 rotates, and the workpiece at the finished product position 13 can be collected as a finished product; and the position of the positioning member 14 after the press-fitting position 111 is the installation position 15, which is used as the installation position for the workpiece 200 to be processed, and the positioning member 14 at the installation position 15 moves to the press-fitting position 111 after the next rotation of the rotating seat 12. During the processing, the workpiece 200 to be processed is first placed on the positioning member 14 at the installation position 15, and then the rotating seat 12 rotates to move the workpiece 200 to be processed at the installation position 15 to the press-fitting position 111 for press-fitting, and at this time, the workpiece 200 to be processed can continue to be installed at the installation position 15; the rotating seat 12 rotates again, so that the workpiece at the press-fitting position 111 (the workpiece 200 to be processed with the part 100 pressed) moves to the finished product position 13 and can be transferred from the finished product position 13, and the workpiece 200 to be processed at the installation position 15 moves to the press-fitting position 111 for press-fitting, and the rotating seat 12 rotates in sequence, so that the workpiece 200 to be processed is installed, pressed and transferred in sequence, and then the workpiece 200 to be processed is formed into a workpiece in sequence and transferred and collected.

[0027] Further references Figure 4 and Figure 5In some specific embodiments, the positioning member 14 can be provided with a positioning groove 141, and the shape of the positioning groove 141 can be adapted to the outer contour of the workpiece 200 to be processed, so that when the workpiece 200 to be processed is installed on the positioning member 14, the workpiece 200 to be processed can be completely or approximately completely in contact with the wall forming the positioning groove 141. At this time, the wall forming the positioning groove 141 can position the workpiece 200 to be processed. The rotating seat 12 can be connected to a rotating drive component such as a motor so that the rotating seat 12 can be driven to rotate. When three positioning members 14 are provided, the rotating seat 12 can rotate 120° each time so that multiple positioning members 14 rotate in sequence. In other embodiments, the positioning member 14 can be used to clamp the workpiece 200 to be processed, or the positioning member 14 can also be connected to the workpiece 200 to be processed using other detachable connection structures.

[0028] Further references Figure 3 、 Figure 6 and Figure 7 The clamping unit 2 is used to clamp and fix the part 100, and the clamping unit 2 can be driven by the driving unit 3 to move toward the press-fitting position 111, so that the part 100 can be press-fitted on the workpiece 200 to be processed on the press-fitting position 111. The clamping unit 2 may include a placement part 21 and a clamping part 22. The placement part 21 is used to accommodate the part 100, and the clamping part 22 fixes the part 100 accommodated in the placement part 21. Specifically, the placement part 21 is provided with a receiving cavity 212 for accommodating the part 100 and a first opening 213 and a second opening 214 communicated with the receiving cavity 212. The first opening 213 can serve as the installation port of the part 100, that is, the part 100 can be moved from the outside of the first opening 213 to the inside of the receiving cavity 212. The second opening 214 allows the clamping part 22 to extend into the receiving cavity 212. When the part 100 moves into the accommodating cavity 212, the clamping member 22 can move from the second opening 214 into the accommodating cavity 212 to secure the part 100. After the part 100 is press-fitted onto the workpiece 200, the clamping member 22 can move away from the accommodating cavity 212 to release the part 100. The clamping member 22 can be a pneumatic cylinder, and the pneumatic telescopic rod of the cylinder is used to extend from the second opening 214 into the accommodating cavity 212 to press the part 100.

[0029] In some specific embodiments, the first opening 213 and the second opening 214 are located on adjacent sides of the storage member 21. For example, the first opening 213 is located on the rear side of the storage member 21, and the second opening 214 is located on the left or right side of the storage member 21. When the first opening 213 and the second opening 214 are located on opposite sides of the storage member 21, the first opening 213 and the second opening 214 are disposed opposite each other. In this case, the direction of movement of the clamping member 22 into the accommodating cavity 212 is toward the first opening 213. The clamping member 22 can only be secured by adding a clamping structure and directly clamping the fixed component 100 through the clamping structure, which results in a complex clamping structure. By setting the first opening 213 and the second opening 214 as adjacent sides of the storage part 21, the opposite side of the second opening 214 forms the wall of the accommodating cavity 212. At this time, the clamping member 22 only needs to tighten the part 100. One end of the part 100 contacts the clamping member 22, and the other end of the part 100 contacts the wall forming the accommodating cavity 212, so that the part 100 can be clamped. There is no need to set up an additional structure to clamp and fix the part 100, and the structure is simple.

[0030] After the part 100 is fixed to the placement member 21, the placement member 21 will be driven by the driving unit 3 to move toward the pressing position 111. To ensure that the part 100 located in the placement member 21 can always remain fixed when the placement member 21 moves, the clamping unit 2 can be provided with a first mounting plate 23 for mounting the object 21 and the clamping member 22. The placement member 21 and the clamping member 22 can be respectively fixed to the first mounting plate 23 by fasteners such as screws and kept in relative position. When the driving unit 3 drives any one of the first mounting plate 23, the placement member 21, and the clamping member 22 to move, the first mounting plate 23, the placement member 21, and the clamping member 22 will all move synchronously. Therefore, the clamping member 22 can move with the placement member 21, so that the clamping member 22 can always press and fix the part 100 located in the placement member 21.

[0031] The driving unit 3 may be in contact with the object placement member 21 in the clamping unit 2, so that the driving unit 3 drives the object placement member 21 and the part 100 located in the object placement member 21 to move. The driving unit 3 may be a cylinder.

[0032] When the conventional drive unit 3 drives the placement member 21, the drive unit 3 operates at a consistent speed. The placement member 21 and the part 100 located therein are moved at a constant speed and pressed into the workpiece 200. Because the drive unit 3 typically operates at a relatively high speed, the part 100 is susceptible to significant instantaneous impact during press-fitting, causing deformation. Furthermore, after the part 100 is press-fitted, the drive unit 3 lacks restraint, potentially allowing it to continue pressing the part 100. This can cause the part 100 to over-press and increase the risk of deformation.

[0033] Further references Figure 4 、 Figures 8 to 10 In the present application, the drive unit 3 may be connected to a buffer unit 4, which is used to buffer the drive unit 3 during its operation to reduce or prevent the risk of over-pressing and deformation of the part 100. Specifically, the buffer unit 4 may include a fixed stop plate 41, as well as an elastic buffer 42 and a hard buffer 43 connected to the drive unit 3. The stop plate 41 is fixed in position. When the drive unit 3 drives the placement member 21 to move, the stop plate 41 does not move in the pressing direction. However, the elastic buffer 42 and the hard buffer 43 connected to the drive unit 3 move synchronously when the drive unit 3 drives the placement member 21. For example, the drive unit 3 includes a housing and a telescopic member located within the housing. The telescopic member can be a pneumatic telescopic rod of a cylinder. When the drive unit 3 is in operation, the housing remains fixed, and the telescopic member telescopes to drive the placement member 21. The stop plate 41 remains fixed to the housing of the drive unit 3 and is located in front of the elastic buffer 42 and the hard buffer 43 along the direction of movement of the placement member 21. The elastic buffer member 42 and the hard buffer member 43 are fixedly connected to the telescopic member of the driving unit 3 so that the elastic buffer member 42 and the hard buffer member 43 can move synchronously with the telescopic member.

[0034] The distance between the elastic buffer 42 and the limiting plate 41 in the free state is smaller than the distance between the hard buffer 43 and the limiting plate 41. Figures 8 to 10 , Figure 8 This is the state when the driving unit 3 starts to drive the clamping unit 2. When the driving unit 3 is working, the elastic buffer 42 and the hard buffer 43 will move synchronously toward the limit plate 41, and the elastic buffer 42 will first contact the limit plate 41. Figure 9 , Figure 9 This is the state when the elastic buffer 42 contacts the limit plate 41. When the elastic buffer 42 contacts the limit plate 41, it will be compressed and will apply resistance to the movement of the drive unit 3. At this time, the driving speed of the drive unit 3 is reduced, and the movement speed of the storage part 21 and the part 100 is reduced; and, in the further movement process of the drive unit 3, as the degree of compression of the elastic buffer 42 increases, the elastic potential energy of the elastic buffer 42 increases, so that the resistance applied to the drive unit 3 increases, and the driving speed of the drive unit 3 gradually decreases. Therefore, when the part 100 is pressed onto the workpiece 200 to be processed, the part 100 will not be violently impacted, effectively reducing the risk of deformation of the part 100 due to the large instantaneous impact. And in the process of the part 100 being pressed into place without interference, the elastic buffer is continuously used and the buffering force is continuously increased, which more effectively reduces the risk of deformation. Refer to Figure 10 , Figure 10This is the state when the hard buffer 43 contacts the limit plate 41. When the part 100 is pressed into place, the hard buffer 43 contacts the limit plate 41 and forms hard contact with the limit plate 41, thereby limiting the further movement of the drive unit 3. At this time, the drive unit 3 stops due to the restriction of the hard buffer 43 to prevent the part 100 from being pressed into place too much, thereby ensuring the pressing accuracy of the part 100.

[0035] The elastic buffer 42 is used to limit the driving unit 3 once to reduce the driving speed of the driving unit 3. When the part 100 is pressed into the workpiece 200, the pressing speed is reduced, which can effectively reduce the risk of deformation of the part 100. In addition, by providing the elastic buffer 42, the driving unit 3 can maintain an accelerated driving speed and ensure the pressing force when it starts to drive the placement member 21 to move because it is not restricted by the elastic buffer 42, thereby reducing the time of the press-fitting operation. The driving speed is also reduced when the elastic buffer 42 contacts the limiter. At this time, the part 100 is about to be pressed into the workpiece 200 or has just contacted the workpiece 200, which can reduce the press-fitting operation time and reduce the risk of deformation of the part 100. By providing the hard buffer 43, the press-fitting position 111 of the part 100 can be positioned. When the part 100 is pressed into place, the hard buffer 43 can come into hard contact with the limiter 41 to stop the driving unit 3, thereby achieving a secondary restriction on the driving unit 3, preventing the part 100 from being pressed into place.

[0036] Further references Figures 8 to 10 In some specific embodiments, the elastic buffer 42 includes a retractable telescopic rod 421 and an elastic member 422 sleeved on the telescopic rod 421. The telescopic rod 421 includes a head with a relatively large diameter and a rod with a relatively small diameter. The elastic member 422 is sleeved on the rod of the telescopic rod 421, and one end abuts against the head of the telescopic rod 421. When the elastic buffer 42 contacts the limit plate 41, the head of the telescopic rod 421 first contacts the limit plate 41 and generates a retraction movement. At this time, the head of the telescopic rod 421 squeezes the elastic member 422 to apply resistance to the movement of the drive unit 3. The hard buffer 43 can be a hard material. The hard buffer 43 can directly contact the limit plate 41. For example, the hard buffer 43 is a relatively hard metal part or hard plastic. The limit plate 41 can also be a relatively hard metal part or hard plastic.

[0037] Further references Figure 11In some specific embodiments, the buffer unit 4 may further include a third buffer 44. The third buffer 44 may be used to limit the movement of the driving unit 3 to form multiple safeguards in conjunction with the hard buffer 43 and the elastic buffer 42. The third buffer 44 may be installed in the clamping unit 2 and connected to the driving unit 3. For example, the third buffer 44 may be installed in the placement member 21 of the clamping unit 2. Specifically, the placement member 21 may be provided with a through cavity 211, and the third buffer 44 is provided in the through cavity 211. When the placement member 21 moves toward the workpiece 200 to be processed, the workpiece 200 to be processed may pass through the accommodating cavity 212 of the placement member 21 and extend into the through cavity 211 and abut against the third buffer 44. By controlling the installation position 15 of the third buffer 44, when the part 100 is pressed into place, the third buffer 44 abuts against the workpiece 200 to be processed and forms hard contact. The third buffer member 44 can abut against the drive unit 3 and is located between the drive unit 3 and the workpiece 200. When the third buffer member 44 makes hard contact with the workpiece 200, it also makes hard contact with the drive unit 3, thereby limiting further movement of the drive unit 3 and preventing the part 100 from being over-pressed. The axial end of the workpiece 200 passes through the accommodating cavity 212 of the storage member 21 and extends into the through cavity 211, abutting against the third buffer member 44, thereby ensuring hard contact between the third buffer member 44 and the workpiece 200.

[0038] The feeding unit 5 is used to move the part 100 from the first opening 213 of the object storage member 21 to the accommodating chamber 212 of the object storage member 21. The feeding unit 5 may include a part support 51 and a feeding drive 52 for driving the part support 51 to move. The part 100 can be placed on the part support 51. The feeding drive 52 is used to drive the part support 51 to move toward the accommodating chamber 212, so that the portion of the part support 51 used to support the part 100 can move from the first opening 213 to the accommodating chamber 212. After the clamping member 22 fixes the part 100 in the accommodating chamber 212, the feeding drive 52 can drive the part support 51 out of the accommodating chamber 212. The feeding drive 52 may specifically be a cylinder.
