Because the sealing piston has a small installation space in the clutch, the sealing piston needs to be placed on the upper pressure head and pressed onto the clutch product through the press-fitting equipment. During the press-fitting process, since the sealing lip of the sealing piston is made of soft rubber material, the rigid pressure head is not flexible, and the sealing piston is not placed flat, the lip is prone to cutting, flanging, and incomplete pressing during the pressing process, resulting in assembly failure; when the press-fitting exceeds the stroke, it is easy to cause poor clutch sealing or lip damage, and it will also cause damage to the press-fitting equipment mechanism or overload damage to the drive motor. Summary of the invention

[0021] In any of the above technical solutions, further, the elastic component is a rectangular spring.

[0022] Compared with the prior art, the beneficial effects of this application are:

[0023] The pressing equipment provided by the present application includes: a main body, a rotating lifting component and an elastic component, wherein the main body has a cylindrical structure, the rotating lifting component and the elastic component are both arranged inside the main body, the rotating lifting component includes a fixed part and a transmission part, the transmission part is movably connected to the fixed part, the transmission part can rotate relative to the fixed part with the fixed part as the center, and during the rotation of the transmission part, the rotational movement of the transmission part can be converted into linear motion, so that the transmission part can move relative to the fixed part, and in a state where the fixed part is extended in a vertical direction, the transmission part can rise (or fall) relative to the fixed part; the elastic component is simultaneously sleeved on the transmission part and the fixed part, the transmission part is formed with a step part, and at least part of the elastic component can abut against the step part, so that when the transmission part moves relative to the fixed part, a force can be applied to the elastic component to cause the elastic component to deform.

[0024] Specifically, when the present pressing device is in use, the workpiece to be pressed, such as a clutch component, is placed on the end surface of the transmission part away from the fixed part, the sealing piston is placed on the clutch component, and then the loading ram presses the sealing piston into the clutch component. When the loading ram continues to apply force to the workpiece to be pressed, the force is transmitted to the transmission part, and under the action of the force, the transmission part starts to rotate relative to the fixed part, and then the rotational motion is converted into linear motion, so that the transmission part moves downward relative to the fixed part, that is, the transmission part rotates and descends relative to the fixed part, and at the same time, the elastic member is squeezed to compress the elastic member. Under the action of the elastic member, the transmission part has a floating characteristic in the process of descending, which has an adjustment effect when the workpiece (such as the sealing piston) is uneven. The floating effect can The local concentrated force on the workpiece is offset, so that the forces on various parts of the workpiece are almost balanced, and the sealing piston lip is avoided from being trimmed, flanging or not fully pressed in, ensuring the assembly effect and improving the assembly qualification rate. At the same time, it can also balance the force applied by the loading ram. Due to the compression effect of the elastic component, even if the loading ram is pressed over the stroke, it will not damage the components, structure or motor of the loading ram. When the pressing is completed and the loading ram is separated from the workpiece to be pressed and no longer applies force, the elastic component is gradually stretched and restored to its original state due to its own characteristics. In this process, the elastic component applies elastic force to the step portion of the transmission part, so that the transmission part rotates in the opposite direction, and at the same time converts the rotational motion into linear motion, so that the transmission part rises relative to the fixed part and automatically returns to its original position.

[0025] It can be seen that the pressing equipment provided by the present application can avoid the cutting, flanging or incomplete pressing of the sealing piston lip, ensure the assembly effect, and improve the assembly qualification rate. At the same time, it can also balance the force applied by the loading pressure head. Due to the compression effect of the elastic component, even if the loading pressure head is pressed over the stroke, it will not damage the loading pressure head, motor and other components. It has high synchronization, simple structure and high reliability. It does not require a power source and does not need to adjust the synchronization of rotation and pressing. After the rotation pressing is completed, it can automatically reset under the action of the spring rebound force. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Refer to the following Figure 1 and Figure 2 The present invention describes a press-fitting device according to some embodiments of the present application.

[0037] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a press-fitting device, comprising: a main body 4, a rotating lifting component and an elastic component 1; the rotating lifting component and the elastic component 1 are arranged inside the main body 4; the elastic component 1 is sleeved on the rotating lifting component; the rotating lifting component comprises a fixed part and a transmission part connected to the fixed part, and the transmission part can move relative to the fixed part; at least part of the elastic component 1 abuts against the transmission part, and the elastic component 1 is deformed as the transmission part moves relative to the fixed part.

[0038] Furthermore, the elastic component 1 is a rectangular spring with maximum load-bearing capacity and extended service life, which greatly reduces the production risks caused by using inferior springs, improves production efficiency, and saves operating costs. Of course, the specific form of the elastic component 1 is not limited to this.

[0039] In this embodiment, the pressing equipment provided by the present application includes: a main body 4, a rotating lifting component and an elastic component 1, wherein the main body 4 has a cylindrical structure, the rotating lifting component and the elastic component 1 are both arranged inside the main body 4, the rotating lifting component includes a fixed part and a transmission part, the transmission part is movably connected to the fixed part, the transmission part can rotate relative to the fixed part with the fixed part as the center, and during the rotation of the transmission part, the rotational movement of the transmission part can be converted into linear motion, so that the transmission part can move relative to the fixed part, and when the fixed part is extended in the vertical direction, the transmission part can rise (or fall) relative to the fixed part; the elastic member 1 is simultaneously sleeved on the transmission part and the fixed part, the transmission part is formed with a step part, and at least a part of the elastic member 1 can abut against the step part, so that when the transmission part moves relative to the fixed part, a force can be applied to the elastic member 1 to cause the elastic member 1 to deform.

[0040] Specifically, when the present pressing device is in use, the workpiece to be pressed, such as a clutch component 7, is placed on the end surface of the transmission part away from the fixed part, the sealing piston 6 is placed on the clutch component 7, and then the loading ram presses the sealing piston 6 into the clutch component 7. When the loading ram continues to apply force to the workpiece to be pressed, the force is transmitted to the transmission part, and under the action of the force, the transmission part starts to rotate relative to the fixed part, and then the rotational motion is converted into linear motion, so that the transmission part moves downward relative to the fixed part, that is, the transmission part rotates and descends relative to the fixed part, and at the same time, the elastic member 1 is squeezed to compress the elastic member 1. Under the action of the elastic member 1, the transmission part has a floating characteristic in the process of descending, and has an adjustment effect when the workpiece (such as the sealing piston 6) is uneven. The floating effect It can offset the local concentrated force on the workpiece, so that the forces on various parts of the workpiece are almost balanced, avoid cutting, flanging or incomplete pressing of the lip of the sealing piston 6, ensure the assembly effect, and improve the assembly qualification rate. At the same time, it can also balance the force applied by the loading ram. Due to the compression effect of the elastic component 1, even if the loading ram is pressed over the stroke, it will not damage the components, structure or motor of the loading ram. When the pressing is completed and the loading ram is separated from the workpiece to be pressed and no longer applies force, the elastic component 1 is gradually stretched and restored to its original state due to its own characteristics. In this process, the elastic component 1 applies elastic force to the step portion of the transmission part, so that the transmission part rotates in the opposite direction, and at the same time converts the rotational motion into linear motion, so that the transmission part rises relative to the fixed part and automatically returns to its original position.

[0041] It can be seen that the pressing equipment provided by the present application can avoid the lip of the sealing piston 6 from being cut, flanging or not being fully pressed in, thereby ensuring the assembly effect and improving the qualified assembly rate. At the same time, it can also balance the force applied by the loading pressure head. Due to the compression effect of the elastic component 1, even if the loading pressure head is pressed over the stroke, it will not damage the loading pressure head, motor and other components. It has high synchronization, simple structure and high reliability. It does not require a power source or debugging of the synchronization of rotation and pressing. After the rotation pressing is completed, it can automatically reset under the action of the spring rebound force.

[0042] In one embodiment of the present application, preferably, Figure 2 As shown, the fixed part of the rotating lifting member is a rod member 2, and one end of the rod member 2 is connected to the body 4;

[0043] The transmission part is a transmission component 3 which is sleeved on the rod component 2 , and the transmission component 3 is threadedly connected to the rod component 2 .

[0044] Furthermore, the transmission component 3 includes a nut seat 301 and a rotating shaft 302; the nut seat 301 is threadedly connected to the rod member 2, and the nut seat 301 is formed with a flange 303 (i.e. the above-mentioned step portion), the flange 303 is connected to the rotating shaft 302, and the rotating shaft 302 extends axially along the nut seat 301.

[0045] In this embodiment, the fixed part of the rotating lifting component is a rod component 2, which can be a trapezoidal screw or a ball screw, but is not limited to this. An external thread is formed on its surface; the transmission part of the rotating lifting component is a transmission component 3, which includes a nut seat 301 and a rotating shaft 302 that are connected to each other. The nut seat 301 is formed with a flange 303, and the rotating shaft 302 also has a sleeve structure, and one end of the rotating shaft 302 is connected to the flange 303 of the nut seat 301. The connection strength between the two can be ensured by welding, riveting or key connection, so that the rotating shaft 302 and the nut seat 301 both extend in the vertical direction and can move synchronously.

[0046] In addition, at least the inner wall of the nut seat 301 is formed with an internal thread, or the nut seat 301 and the rotating shaft 302 are an integral structure, and the nut seat 301 and the rotating shaft 302, i.e., the inner wall of the transmission member 3, which have an integral structure, are formed with an internal thread. The internal thread described here is adapted to the external thread on the surface of the rod member 2, so that the transmission part can be threadedly connected to the fixed part, and when the transmission part is subjected to force, it can rotate relative to the fixed part and rise or fall.

[0047] In one embodiment of the present application, preferably, Figure 2 As shown, a bearing table 3021 is formed at one end of the rotating shaft 302 away from the rod member 2 for bearing the workpiece to be pressed.

[0048] Furthermore, the press-fitting device further includes a loading component, and the loading component faces the bearing table 3021 .

[0049] In this embodiment, the loading member may be a common press in the prior art, and the force-applying component of the loading member is a loading press head, which acts on the workpiece to be press-fitted, for example, press-fitting the sealing piston 6 to the clutch component 7 .

[0050] The area of ​​the bearing table 3021 is larger than the area of ​​the cross section of the rotating shaft 302 , so that the bearing table 3021 has a sufficient area to bear the workpiece to be pressed, and also facilitates the connection between the rotating shaft 302 and the body 4 .

[0051] In one embodiment of the present application, preferably, Figure 2 As shown, the body 4 includes a first connecting plate 401, a second connecting plate 402 and a guide cylinder 403;

[0052] The first connecting plate 401 is disposed at an opening at one end of the guide cylinder 403;

[0053] The second connecting plate 402 is disposed at the other end opening of the guide tube 403 , and the edge of the second connecting plate 402 is connected to the guide tube 403 .

[0054] Furthermore, the first connecting plate 401 is provided with a first through hole for passing the rotating shaft 302, and the rotating shaft 302 is connected to the first connecting plate 401 via a bearing 5;

[0056] Furthermore, the locking portion 201 is formed with a locking hole, and the locking hole is used to pass the set screw 202 , and the set screw 202 is provided with a locking nut 203 adapted to the set screw 202 .

[0057] In this embodiment, the guide cylinder 403 can be a cylindrical cylinder with openings at both ends. The first connecting plate 401 blocks the opening of one end of the guide cylinder 403 (the upper end opening as shown in the figure), and the second connecting plate 402 blocks the opening of the other end of the guide cylinder 403 (the lower end opening as shown in the figure). The end of the rotating shaft 302 away from the rod member 2 passes through the first through hole, so that the bearing table 3021 of the rotating shaft 302 extends out of the first connecting plate 401, and the rotating shaft 302 and the first connecting plate 401 are connected by a bearing 5 (preferably, the bearing 5 can be a deep groove ball bearing, of course, not limited to this), so that the first connecting plate 401 remains unchanged when the rotating shaft 302 is rotated under force, and there is no connection between the edge of the first connecting plate 401 and the side wall of the guide cylinder 403, so that when the workpiece to be pressed is uneven or the loading press head exceeds the stroke, the first connecting plate 401 floats with the elastic member 1, thereby avoiding damage to the workpiece to be pressed and improving the assembly effect. The second connecting plate 402 is connected to the guide cylinder 403 , so that the second connecting plate 402 can stably support the rod member 2 .

The penetration direction of the locking hole is preferably consistent with the radial direction of the first connecting plate 401. After the locking portion 201 passes through the second through hole, a set screw 202 (preferably, the set screw 202 is a cone-end set screw) is inserted into the locking hole and locked with a locking nut 203 to enhance the stability of the rod member 2 and the overall rotating and lifting member.

[0059] In one embodiment of the present application, preferably, Figure 2 As shown, the length of the rod member 2 is smaller than the distance between the first connecting plate 401 and the second connecting plate 402 .

[0060] In this embodiment, the length of the rod member 2 is smaller than the distance between the first connecting plate 401 and the second connecting plate 402, so that a certain space is formed between the top end of the rod member 2 and the first connecting plate 401, which is used to determine the lifting and lowering stroke of the rotating shaft 302 (specifically, it can be regarded as the supporting table 3021).

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
