[0047] like Figure 1 and Figure 2 As shown, this embodiment provides a riveting device, which includes a base 10, a fixing assembly 20, a pressing head assembly 30 and a rivet head assembly 40. A pressing system 11 is provided on the base 10, and the fixing assembly 20 is arranged on the base 10 for fixing the product to be assembled; the pressing head assembly 30 and the rivet head assembly 40 are both arranged on the base 10, and the pressing head assembly 11 can sequentially drive the pressing head assembly 30 and the rivet head assembly 40 to move toward the direction close to the fixing assembly 20, so that the pressing head assembly 30 presses the bearing onto the product to be assembled for the first time, and the rivet head assembly 40 re-presses the bearing and the product to be assembled after the initial press-fitting, so that the product to be assembled is deformed and squeezed to fix the bearing.

[0048] By arranging a fixing component 20 on the base 10, the fixing component 20 is used to fix the product to be combined on the base 10, so that the position of the product to be combined is accurate and remains stationary, which is convenient for determining the bearing position during installation; the pressing system 11 first drives the pressing head component 30 to approach the fixing component 20, and the pressing head component 30 presses the bearing onto the product to be combined for the first time. The pressing system 11 then drives the rivet head component 40 to approach the fixing component 20, and the rivet head component 40 re-presses the bearing and the product to be combined to deform the product to be combined, thereby squeezing and fixing the bearing, which can improve the stability and durability of the bearing installation and prevent the bearing from loosening or falling off when rotating at high speed or bearing heavy loads.

[0049] In this embodiment, the first direction is horizontal, and the second direction is vertical. The base 10 is vertically mounted on the ground, the press system 11 is located on the top of the base 10, the fixing assembly 20 is located on the bottom of the base 10, and the press head assembly 30 and the rivet head assembly 40 are located in the middle of the base 10 and are both movable vertically relative to the base 10. The press system 11 is a servo press system, a high-precision press assembly device that utilizes servo control technology. It achieves precise control of speed and pressure through servo motor drive, thereby ensuring press assembly quality.

[0050] In this embodiment, the fixing assembly 20 includes a base plate and a clamping member. The base plate is mounted on the base 10, and the clamping member is mounted on the base plate. The clamping member is used to clamp the products to be assembled. The base plate and base 10 are detachably connected by bolts. The base plate can be a circular plate, and the clamping member can be a plurality of claws that slide radially on the base plate. The multiple claws can move closer or farther away from each other to accommodate products of different sizes to be assembled.

[0051] Furthermore, the riveting device further includes a sliding member 52, which is slidably arranged on the base 10 in the horizontal direction, the pressing head assembly 30 and the rivet head assembly 40 are arranged side by side on the sliding member 52 in the horizontal direction, the pressing system 11 and the fixing assembly 20 are spaced apart in the vertical direction, and the pressing head assembly 30 and the rivet head assembly 40 are both slidably connected to the sliding member 52 in the vertical direction. By providing the sliding member 52, the sliding member 52 is slidably arranged on the base 10 in the horizontal direction, and when the sliding member 52 moves, the pressing head assembly 30 and the rivet head assembly 40 are driven to move in the horizontal direction, so that the horizontal position of the pressing head assembly 30 and the rivet head assembly 40 is adjustable; when the pressing head assembly 30 moves in the horizontal direction to above the product to be assembled, the pressing system 11 drives the pressing head assembly 30 to descend in the vertical direction to complete the initial press-fitting; when the rivet head assembly 40 moves in the horizontal direction to above the product to be assembled, the pressing system 11 drives the rivet head assembly 40 to descend in the vertical direction to complete the re-pressing operation.

[0052] Optionally, the press system 11 is provided with a plug-in end, and the sliding member 52 drives the press head assembly 30 and the rivet head assembly 40 to move in the horizontal direction so that the plug-in end can be slidably plugged into the press head assembly 30 or the rivet head assembly 40. By providing the plug-in end to be slidably plugged into the press head assembly 30 or the rivet head assembly 40, the press system 11 and the press head assembly 30 or the rivet head assembly 40 can be quickly connected or disconnected, without the need to set up two additional systems to drive the press head assembly 30 and the rivet head assembly 40 respectively, thereby simplifying the structure and facilitating control.

[0053] Optionally, the riveting device also includes a driving member 51 arranged on the base 10, and the driving member 51 is used to drive the sliding member 52 to slide along the first direction; the base 10 is provided with a first slide rail 12 extending along the horizontal direction, and the sliding member 52 slides with the base 10 through the first slide rail 12, and at least two first slide rails 12 are arranged side by side in the vertical direction.

[0054] In this embodiment, the sliding member 52 is slidably connected to the two first slide rails 12; the sliding member 52 is flat and extends vertically; the driving member 51 can be a cylinder. Specifically, the driving member 51 is horizontally mounted on the base 10, with the sliding member 52 and the driving member 51 respectively positioned on either side of the base 10. The base 10 has a horizontally extending through hole, into which the sliding member 52 is partially inserted and connected to the output end of the driving member 51.

[0055] By setting up a cylinder to drive the sliding member 52 to slide, the structure is simple and high-precision displacement control can be achieved; by setting up two first slide rails 12, the sliding member 52 can remain stable during the sliding process and has a better load-bearing capacity.

[0056] In other embodiments, the pressing head assembly 30 and the rivet head assembly 40 may be arranged to remain stationary in the horizontal direction, and the fixing assembly 20 may be used to move to a suitable position in the horizontal direction to complete the initial pressing and re-pressing operations in sequence; the pressing head assembly 30 and the rivet head assembly 40 may also be arranged to remain at a constant height, and the fixing assembly 20 may be arranged to rise and fall in the vertical direction to complete the initial pressing and re-pressing operations.

[0057] See also Figure 1 and Figure 3 In this embodiment, a second slide rail 521 is provided on the sliding member 52, and the second slide rail 521 extends in the vertical direction. Two second slide rails 521 are arranged side by side in the horizontal direction, and the pressing head assembly 30 and the rivet head assembly 40 are respectively slidably connected to the two second slide rails 521.

[0058] Furthermore, the base 10 is provided with a slideway 13 extending in the horizontal direction, and the ram assembly 30 and the rivet head assembly 40 are both slidably connected to the slideway 13; the slideway 13 is provided with a notch 131 corresponding to the position of the fixing assembly 20, and the pressing system 11 can drive the ram assembly 30 or the rivet head assembly 40 to enter or exit the slideway 13 through the notch 131. By providing the slideway 13 and the notch 131 on the slideway 13, the stability of the ram assembly 30 and the rivet head assembly 40 in the horizontal direction can be enhanced, and the downward pressing operation of the ram assembly 30 and the rivet head assembly 40 will not be restricted.

[0059] In this embodiment, the notch 131 is located directly above the fixing assembly 20; when the pressing head assembly 30 (or the rivet head assembly 40) is not at the notch 131, it means that the position of the pressing head assembly 30 (or the rivet head assembly 40) does not match the position of the fixing assembly 20 in the horizontal direction, and the horizontal position of the pressing head assembly 30 (or the rivet head assembly 40) still needs to be adjusted; once the pressing head assembly 30 (or the rivet head assembly 40) moves horizontally to the notch 131, the pressing head assembly 30 (or the rivet head assembly 40) can be driven downward by the pressing system 11, thereby disengaging the pressing head assembly 30 (or the rivet head assembly 40) from the slide 13, thereby descending in the vertical direction to complete the pressing operation.

[0060] See also Figure 1 and Figure 4 The pressing head assembly 30 includes a press-fitting structure 31, a first fixed seat 32 and a first sliding seat 33. The first fixed seat 32 slides with the slide 13 through a deep groove ball bearing. The first sliding seat 33 is slidably set on the sliding member 52 through the second slide rail 521. The two ends of the first sliding seat 33 are respectively connected to the first fixed seat 32 and the press-fitting structure 31. The press-fitting structure 31 is used to press the bearing.

[0061] When the driving member 51 drives the sliding member 52 to move in the horizontal direction, the sliding member 52 can drive the first sliding seat 33, the pressing structure 31 and the first fixed seat 32 to move synchronously in the horizontal direction; when the pressing system 11 drives the first fixed seat 32 to move in the vertical direction, it drives the first sliding seat 33 to slide on the second slide rail 521, thereby driving the pressing structure 31 to rise and fall in the vertical direction.

[0062] See also Figures 4 to 7 The press-fitting structure 31 includes a press head 311 and a spring plunger 313. The press head 311 is used for the bearing to be mounted. The press head 311 is provided with a spring plunger 313 for stopping the bearing. The press system 11 can drive the press head 311 and the spring plunger 313 to move synchronously. By providing the spring plunger 313 on the press head 311, when the bearing is mounted on the press head 311, the spring plunger 313 can stop the bearing and prevent the bearing and the press head 311 from separating during the vertical movement of the press head 311. After the bearing and the press head 311 move to the vicinity of the position of the fixed assembly 20, the press head 311 presses down to preliminarily press the bearing into the product to be assembled, and then the press head 311 rises in the vertical direction and separates from the bearing. In this embodiment, three spring plungers 313 are evenly spaced along the axial direction of the press head 311, and the spring plungers 313 extend radially along the press head 311.

[0063] Optionally, the press-fitting structure 31 further includes an auxiliary member 312 that is slidably mounted on the press head 311. An annular space is defined between the auxiliary member 312 and the press head 311 for accommodating and circumferentially limiting the bearing. The auxiliary member 312 allows the bearing to be positioned between the auxiliary member 312 and the press head 311, thereby limiting the bearing's position.

[0064] Optionally, auxiliary member 312 is provided with a calibration surface 3121 for contact with the product to be assembled. By providing calibration surface 3121 on auxiliary member 312, prior to initial press-fitting, the press head assembly 30 needs to be pressed down close to the product to be assembled, and calibration surface 3121 is used to contact the product to determine the relative position of the product to be assembled and the bearing.

[0065] In this embodiment, the auxiliary part 312 is disc-shaped, and three jaws are protruding from the auxiliary part 312. The three jaws are evenly spaced around the pressure head 311. The three jaws are located on the outer periphery of the bearing and are used to limit the outer peripheral surface of the bearing; the inner surface of the jaws is recessed to form a fan-ring-shaped calibration plane, and the calibration planes of the three jaws constitute the calibration surface 3121.

[0066] In this embodiment, the pressing structure 31 also includes a first pressing block 314, a first positioning block 315 and a first elastic member 316. The first pressing block 314 is connected to the first sliding seat 33. The top of the pressing head 311 is fixed on the first pressing block 314. The first positioning block 315 is slidingly connected to the first pressing block 314. The bottom end of the pressing head 311 is slidably passed through the first positioning block 315. The two ends of the first elastic member 316 are respectively against the pressing head 311 and the first positioning block 315. The auxiliary member 312 is fixed on the first positioning block 315. The first elastic member 316 can be a spring.

[0067] When press-fitting the bearing, first control the pressing head assembly 30 to move downward in the vertical direction. When the calibration surface 3121 of the auxiliary part 312 is in contact with the product to be assembled, the auxiliary part 312 and the first positioning block 315 will not be able to continue to descend. As the first sliding seat 33 continues to move downward, the first sliding seat 33 presses the pressing head 311 downward through the first pressing block 314, so that the first elastic part 316 is in a compressed state, and the pressing head 311 presses the bearing into the product to be assembled.

[0068] Optionally, the riveting device further includes a first displacement sensor 61 , which is connected to the first pressing block 314 of the pressing head assembly 30 and is used to detect the initial pressing distance.

[0069] See also Figures 8 to 10The rivet head assembly 40 includes a re-pressing structure 41, a second fixed seat 42 and a second sliding seat 43. The second fixed seat 42 slides with the slide 13 through a deep groove ball bearing. The second sliding seat 43 is slidably set on the sliding member 52 through a second slide rail 521. The two ends of the second sliding seat 43 are respectively connected to the second fixed seat 42 and the re-pressing structure 41. The re-pressing structure 41 is used to re-press the bearing and the product to be combined.

[0070] When the driving member 51 drives the sliding member 52 to move in the horizontal direction, the sliding member 52 can drive the second sliding seat 43, the second fixed seat 42 and the re-pressing structure 41 to move synchronously in the horizontal direction; when the pressing system 11 drives the second fixed seat 42 to move in the vertical direction, it drives the second sliding seat 43 to slide on the second slide rail 521, thereby driving the re-pressing structure 41 to rise and fall in the vertical direction.

[0071] The composite pressing structure 41 includes at least two cutting heads 411. The pressing system 11 is capable of driving the cutting heads 411 to move, causing them to act on the periphery of the products to be assembled and radially compress the products from the outside. By utilizing at least two cutting heads 411, the cutting heads 411 can radially compress the products to be assembled from the outside and inscribe marks on the periphery of the products to be assembled, thereby deforming the ends of the products to be assembled, thereby securing the bearing and preventing it from separating from the products to be assembled.

[0072] In this embodiment, the re-pressing structure 41 also includes a second pressure block 412, a third pressure block 413, a second positioning block 414, a second elastic member 415 and a guide column 416. The second pressure block 412 is connected to the second sliding seat 43, the third pressure block 413 is connected to the second pressure block 412 and a mounting member is clamped to fix the cutter head 411; one end of the guide column 416 is connected to the mounting member, the guide column 416 slides through the third pressure block 413, and the other end of the guide column 416 is fixed to the second positioning block 414. The second elastic member 415 is sleeved on the guide column 416 and its two ends respectively rest on the third pressure block 413 and the second positioning block 414; the second elastic member 415 can be a spring.

[0073] When re-pressing the bearing, first control the rivet head assembly 40 to move downward in the vertical direction. When the second positioning block 414 is in contact with the product to be assembled, the second positioning block 414 will not be able to continue to descend. As the second sliding seat 43 continues to move downward, the second sliding seat 43 drives the second pressing block 412 and the third pressing block 413 to descend, so that the second elastic member 415 is in a compressed state. The cutter head 411 gradually descends and extends from the through hole of the second positioning block 414, squeezing the product to be assembled from the outside, causing the product to be assembled to deform to fix the bearing.

[0074] In this embodiment, the second positioning block 414 is square and features a vertically extending positioning post that helps determine the re-pressing position. Four cutting heads 411 are evenly spaced around the positioning post, centered on the post. The presence of four cutting heads 411 helps apply uniform pressure to the product being assembled, resulting in uniform deformation of the product's periphery.

[0075] Optionally, the press riveting device further includes a second displacement sensor 62, which is connected to the second pressure block 412 of the rivet head assembly 40 and is used to detect the re-pressing distance. By providing the first displacement sensor 61 and the second displacement sensor 62, the press-fitting distance can be detected, thereby ensuring that the bearing is press-fitted in place.

[0076] The following is the specific use process of the riveting device:

[0077] The products to be assembled are placed on the fixing assembly 20 at the bottom of the base 10, and the fixing assembly 20 clamps and fixes the products to be assembled; the driving member 51 is located at the head end of the first slide rail 12 on the base 10, and is in the initial state at this time; the driving member 51 drives the sliding member 52 to move in the positive horizontal direction, thereby driving the pressing head assembly 30 and the rivet head assembly 40 on the sliding member 52 to move and gradually approach the products to be assembled in the horizontal direction.

[0078] When the pressing head assembly 30 moves to above the product to be assembled, the pressing head assembly 30 is plugged into the pressing system 11, and the sliding member 52 stops moving in the horizontal direction; the pressing system 11 drives the pressing head assembly 30 to descend in the vertical direction, and then press-fits the bearing for the first time. After the initial press-fitting is completed, the pressing head assembly 30 rises and resets in the vertical direction.

[0079] Then the sliding member 52 continues to move in the horizontal direction, the pressing head assembly 30 and the pressing system 11 are disengaged, and when the rivet head assembly 40 moves above the product to be assembled, the rivet head assembly 40 is plugged into the pressing system 11, and the sliding member 52 stops moving in the horizontal direction; the pressing system 11 drives the rivet head assembly 40 to descend in the vertical direction, and the cutter head 411 gradually extends, thereby completing the re-pressing to deform the product to be assembled and thereby squeezing the fixed bearing. After the re-pressing is completed, the rivet head assembly 40 rises and resets in the vertical direction; at this time, the driving member 51 is located at the end position of the first slide rail 12 on the base 10, and the driving member 51 is used to drive the sliding member 52 to move in the opposite horizontal direction, thereby driving the pressing head assembly 30 and the rivet head assembly 40 on the sliding member 52 to move until it returns to its initial state.

[0080] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
