[0024] The present invention achieves the following technical effects compared to the prior art:
[0025] This invention provides a press-fitting and mortise-and-tenon assembly tooling and method, comprising a housing assembly, a mortise-and-tenon housing, a press-fitting head, a floating rotor, a first elastic component, and a press-fitting shaft. One end of the housing assembly has a first inner cavity extending along a first direction, which is the length direction of the housing assembly. At least one side wall of the housing assembly has an irregularly shaped through hole, including a first strip-shaped hole and a second strip-shaped hole located on one side of the first strip-shaped hole. The first strip-shaped hole extends along the first direction, and the second strip-shaped hole communicates with the first strip-shaped hole and extends in a direction perpendicular to the first direction. The mortise-and-tenon housing has a second cavity penetrating through it along the first direction. One end of the mortise-and-tenon housing is fixedly connected to the housing assembly, and the inner wall of the mortise-and-tenon housing has a chamfer at the edge away from the housing assembly. The first end of the press-fitting head is sequentially sleeved on the mortise-and-tenon housing and the housing assembly, and the press-fitting head is slidably connected to the housing assembly. The second end of the press-fitting head can extend outside the mortise-and-tenon housing. The first end of the press-fitting head has a third inner cavity extending along the first direction. At least one side wall of the press-fit head is provided with a press-fit hole that communicates with the third inner cavity and is opposite to the irregular through hole. The press-fit hole has a first inclined surface near the inner side wall of the receiving shell. The end of the first inclined surface near the second strip hole extends away from the receiving shell. A first elastic member is disposed in the third inner cavity. One end of the first elastic member abuts or connects to the inner bottom wall of the third inner cavity. A floating rotor is disposed in the third inner cavity and connected to the end of the first elastic member away from the receiving shell. The press-fit shaft is fixedly connected to the floating rotor. The free end of the press-fit shaft can pass through the press-fit hole and the second strip hole in sequence. The first inclined surface can contact the press-fit shaft when the shell assembly moves relative to the press-fit head toward the receiving shell, and push the press-fit shaft to move toward the first strip hole in the second strip hole until the press-fit shaft enters the first strip hole. The first elastic member can push the press-fit shaft in the first strip hole away from the receiving shell under its own elastic force, and retract the protruding end of the press-fit head into the receiving shell.
[0026] Before pressing, the pressing head is positioned at the end of the second slotted hole furthest from the first slotted hole, so that the second end of the pressing head contacts one end of the workpiece to be processed, and the other end of the workpiece to be processed contacts the other end of the workpiece to be processed. A force is applied to the housing assembly in the direction of the workpiece to be processed, as shown in the figure. The force applied to the right causes the housing assembly to move to the right relative to the pressing head, thereby causing the first inclined surface to contact the outer wall of the pressing shaft. Since the lower end of the first inclined surface is inclined to the left, when the first inclined surface moves to the left, it can apply an upward force to the pressing shaft, causing the pressing shaft to move upward along the second slotted hole and compress the first elastic component. When the pressing shaft has not disengaged from the second slotted hole, the force is transmitted through the pressing and fitting assembly. The tooling is applied to workpiece 1, and workpiece 1 and workpiece 2 are press-fitted together, so that workpiece 1 is completely press-fitted into the mounting groove of workpiece 2 (workpiece 1 and workpiece 2 achieve an interference fit). When the press-fitting shaft disengages from the second slot, the floating rotor can move to the left along the first slot under the action of the first elastic component, causing the second end of the press-fitting head to retract into the retaining housing, leaving space for retaining. Specifically, the left end of workpiece 2 can enter the chamfer of the third inner cavity and contact the inner wall of the chamfer. The inner diameter of the chamfer inner wall gradually decreases from right to left, thereby retaining the left end of workpiece 2. The left end of workpiece 2 deforms to wrap around workpiece 1 inward. In this embodiment, the press-fitting and retaining can be completed in one process, which is beneficial to improving work efficiency and reducing manual labor. Attached Figure Description

[0045] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0046] Example 1
[0047] like Figures 1-12As shown, this embodiment provides a press-fitting and mortise-and-tenon assembly tooling 100, including a housing assembly 1, a mortise-and-tenon housing 2, a press-fitting head 3, a floating rotor 4, a first elastic component 5, and a press-fitting shaft 6. One end of the housing assembly 1 is provided with a first inner cavity extending along a first direction, the first direction being the length direction of the housing assembly 1. At least one side wall of the housing assembly 1 is provided with an irregularly shaped through hole, including a first strip hole 101 and a second strip hole 102 located on one side of the first strip hole 101. The first strip hole 101 extends along the first direction, and the second strip hole 102 is adjacent to the first strip hole 101. 01 is connected, the second strip hole 102 extends in a direction perpendicular to the first direction; the retaining shell 2 has a second cavity penetrating through the retaining shell 2 in the first direction; one end of the retaining shell 2 is fixedly connected to the shell assembly 1, and the inner wall of the retaining shell 2 is provided with a chamfer 201 away from the edge of the shell assembly 1; the first end of the pressing head 3 is sequentially sleeved on the outside of the retaining shell 2 and the shell assembly 1, the pressing head 3 is slidably connected to the shell assembly 1, and the second end of the pressing head 3 can extend out of the retaining shell 2; the first end of the pressing head 3 is provided with a third inner cavity extending in the first direction, and the second end of the pressing head 3 can extend out of the retaining shell 2. A press-fitting hole 301 is provided on one side wall, communicating with the third inner cavity and positioned opposite the irregular through hole. The press-fitting hole 301 has a first inclined surface 302 near the inner wall of the retaining shell 2. The first inclined surface 302 extends from one end near the second strip hole 102 to the end away from the retaining shell 2. A first elastic member 5 is disposed in the third inner cavity. One end of the first elastic member 5 abuts against or connects to the inner bottom wall of the third inner cavity. A floating rotor 4 is disposed in the third inner cavity and connected to the end of the first elastic member 5 away from the retaining shell 2. A press-fitting shaft 6 is fixedly connected to the floating rotor 4 for press-fitting. The free end of the shaft 6 can pass through the press-fit hole 301 and the second strip hole 102 in sequence; the first inclined surface 302 can contact the press-fit shaft 6 when the housing assembly 1 moves relative to the press-fit head 3 in the direction of the receiving housing 2, and push the press-fit shaft 6 in the second strip hole 102 toward the first strip hole 101 until the press-fit shaft 6 enters the first strip hole 101; the first elastic member 5 can push the press-fit shaft 6 in the first strip hole 101 away from the receiving housing 2 under its own elastic force, and retract the protruding end of the press-fit head 3 into the receiving housing 2.
[0048] Before pressing, the pressing shaft 6 is located at the end of the second strip hole 102 away from the first strip hole 101, i.e., the bottom of the second strip hole 102. This causes the second end of the pressing head 3 to contact one end of the workpiece 8 to be processed, and the workpiece 9 to contact the other end of the workpiece 8. A force is applied to the housing assembly 1 in the direction of the workpiece 8 to be processed, as shown in the figure. The force applied to the right causes the housing assembly 1 to move relative to the pressing head 3 to the right, thereby causing the first inclined surface 302 to contact the outer wall of the pressing shaft 6. Since the lower end of the first inclined surface 302 is inclined to the left, when the first inclined surface 302 moves to the left, it can apply an upward force to the pressing shaft 6, causing the pressing shaft 6 to move upward along the second strip hole 102 and compress the first elastic member 5. When the pressing shaft 6 has not disengaged from the second strip hole 102, the force is transmitted through... The press-fitting and mortise-and-tenon assembly tooling 100 is applied to workpiece 8 to press-fit workpiece 8 and workpiece 9, ensuring that workpiece 8 is completely pressed into the mounting groove of workpiece 9 (workpiece 8 and workpiece 9 achieve an interference fit). When the press-fitting shaft 6 disengages from the second slot 102, the floating rotor 4 moves to the left along the first slot 101 under the action of the first elastic component 5, causing the second end of the press-fitting head 3 to retract into the mortise-and-tenon housing 2, leaving space for mortise-and-tenoning. Specifically, the left end of workpiece 9 can enter the chamfer 201 of the third inner cavity and contact the inner wall of the chamfer 201. The inner diameter of the chamfer 201 gradually decreases from right to left, thereby mortise-and-tenoning the left end of workpiece 9, causing the left end of workpiece 9 to deform inward to enclose workpiece 8. In this embodiment, the press-fitting and mortise-and-tenoning can be completed in one process, which is beneficial to improving work efficiency and reducing manual labor.
[0049] It should be noted that both the first strip hole 101 and the second strip hole 102 are connected to the first inner cavity.
[0050] In this specific embodiment, a second elastic component 7 is also included. The second elastic component 7 is disposed in the first inner cavity, and its two ends can be connected to the inner bottom wall of the housing assembly 1 and the end of the press-fit head 3 away from the receiving housing 2, respectively. The inner side wall of the press-fit hole 301 away from the receiving housing 2 has a second inclined surface 303, and the end of the second inclined surface 303 near the second strip hole 102 extends away from the receiving housing 2. Under its own elastic force, the second elastic component 7 can push the press-fit head 3 to move towards the receiving housing 2, and make the second inclined surface 303 contact the press-fit shaft 6, so as to push the press-fit head 3 to move first along the first strip hole 101 towards the second strip hole 102, and then along the second strip hole 102 away from the first strip hole 101. Under the action of the second elastic component 7 and the second inclined surface 303, the press-fit head 3 can automatically reset into the second strip hole 102 to facilitate the next press-fitting and receiving.
[0051] In this specific embodiment, the two opposite side walls of the housing assembly 1 are provided with irregular through holes, wherein the dashed lines in the structural schematic diagram of the housing assembly 1 represent the irregular through holes on the back of the housing assembly 1; the two opposite side walls of the press fitting head 3 are provided with press fitting holes 301, wherein the dashed lines in the structural schematic diagram of the press fitting head 3 represent the press fitting holes 301 on the back of the press fitting head 3; the press fitting shaft 6 is sleeved in the mounting hole of the floating rotor 4, and the two ends of the press fitting shaft 6 pass through the irregular through holes and the press fitting holes 301 on both sides of the floating rotor 4, respectively.
[0052] In this specific embodiment, the height of the side wall of each second strip hole 102 near the receiving shell 2 is higher than the height of the corresponding second strip hole 102 away from the receiving shell 2, so as to prevent the pressing head 3 from moving to the side of the second strip hole 102 near the receiving shell 2 and to ensure that the pressing head 3 can be reset into the second strip hole 102.
[0053] In this specific embodiment, the housing assembly 1 includes a punch holder 103 and a housing 104. One end of the punch holder 103 is detachably fixedly connected to the housing 104, and the other end of the housing 104 is detachably fixedly connected to the receiving housing 2. The press head 3 is slidably connected to the inner wall of the housing. The punch holder 103 is used to be mounted on a stamping press to drive the punch holder 103 to move along a first direction, thereby performing workpiece processing. The detachable connection facilitates the replacement of easily worn parts such as the first elastic component 5, the second elastic component 7, the housing 104, and the floating rotor 4.
[0054] In this specific embodiment, the housing assembly 1 further includes a spring mounting base 105, one end of which is fixedly connected to the punch seat 103, and the other end of which is fixedly connected to the second elastic member 7.
[0055] In this specific embodiment, the punch seat 103 is threaded to one end of the outer shell 104, and the other end of the outer shell 104 is threaded to the receiving shell 2. The structure is simple and easy to disassemble and assemble.
[0056] In this specific embodiment, both the press-fit shaft 6 and the spring mounting base 105 are pins, and both the first elastic component 5 and the second elastic component 7 are springs.
[0057] In this specific embodiment, the chamfer 201 has an angle of 45°. The press-fit hole 301 is approximately rhomboid in shape.
[0058] This embodiment is applicable to the processing of workpieces such as high-frequency connectors that require connection through press-fitting and mortise-and-tenoning processes. After press-fitting, the mortise-and-tenoning housing 2 can be used to mortise-and-tenon the same position on the workpiece. It is highly adaptable, simple to operate, and versatile, saving time and labor. The tooling structure can be adjusted according to the product structure requirements and is reusable. The versatility of this embodiment lies in the ability to design the punch holder 103 and press-fitting head 3 according to the product's shape, and to lock them using the press-fitting shaft 6 and the press-fitting structure (irregular hole), ensuring stability during press-fitting.
[0059] Example 2
[0060] This embodiment provides a pressing and fitting method based on the pressing and fitting assembly tooling 100 of Embodiment 1, including the following steps:
[0061] S1. Make one end of the workpiece 8 to be processed contact with the second end of the press head 3, and make the end of the workpiece 9 to be processed with the mounting groove contact with the other end of the workpiece 8 to be processed.
[0062] S2. Move the housing assembly 1 towards the housing 2 and press the workpiece 8 into the mounting groove using the press head 3. Simultaneously, the first inclined surface 302 contacts the press shaft 6 and pushes the press shaft 6 towards the first slot 101 within the second slot 102 until the press shaft 6 disengages from the second slot 102. The first elastic member 5 pushes the press shaft 6 away from the housing 2 within the first slot 101, causing the second end of the press head 3 to retract into the second cavity. This causes the end of the workpiece 9 near the housing assembly 1 to contact the inner wall of the chamfer 201 of the second cavity and create mutual compression, thus securing the end of the workpiece 9 near the housing assembly 1.
[0063] In this specific embodiment, a second elastic component 7 is also included. The second elastic component 7 is disposed in the first inner cavity. The two ends of the second elastic component 7 can be connected to the inner bottom wall of the housing assembly 1 and the end of the press head 3 away from the receiving housing 2, respectively. The inner side wall of the press hole 301 away from the receiving housing 2 has a second inclined surface 303. The end of the second inclined surface 303 near the second strip hole 102 extends away from the end of the receiving housing 2. The embodiment also includes: S3, removing the workpiece after the receiving process is completed, so that the press head 3 slides relative to the housing assembly 1 under the elastic force of the second elastic component 7, so that the second inclined surface 303 pushes the press head 3 to move first along the first strip hole 101 towards the direction of the second strip hole 102, and then along the second strip hole 102 away from the first strip hole 101, so that the press shaft 6 is reset.
[0064] It should be noted that when the pressing head 3 reaches the set value, the pressing shaft 6 disengages from the second strip hole 102, and the first elastic component 5 is unloaded. After unloading, the elastic force of the second elastic component 7 is less than that of the first elastic component 5, so as to ensure that it still has the function of pressing parts after unloading and to prevent incomplete pressing.
[0065] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
