Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide a riveting device, aiming to solve the technical problem in the prior art that the clamping cannot be self-locked during riveting, resulting in unstable clamping.

[0004] To achieve the above purpose, the technical solution adopted in the embodiments of this application is: providing a riveting device, including two riveting knife assemblies oppositely arranged on both sides of the riveting station, and further including two clamping assemblies oppositely arranged on both sides of the riveting station. The two clamping assemblies are located below the two riveting knife assemblies. The clamping assembly includes a clamping jaw arranged along a first direction, a first sliding member that moves back and forth along the first direction and is fixed to the clamping jaw, a first guiding member arranged along the first direction for the first sliding member to slide on, an elastic component arranged at the end of the first guiding member away from the clamping jaw and connected to the first sliding member, and a first driving member arranged along a second direction. The first direction is perpendicular to the second direction. The driving shaft of the first driving member is provided with a pushing block. The pushing block extends into the first guiding member and contacts the first sliding member. The end of the pushing block has a first inclined surface, and the first sliding member has a second inclined surface. The first inclined surface contacts the second inclined surface.

[0005] Specifically, the first guiding member has a first guiding channel that penetrates the main body of the first guiding member along the first direction, and a second guiding channel that penetrates the main body of the first guiding member along the second direction. The first guiding channel communicates with the second guiding channel. The first sliding member is slidably arranged in the first guiding channel. The pushing block is arranged in the second guiding channel. The end face of the first sliding member close to the pushing block is provided with a first opening. The second inclined surface is arranged in the first opening. The pushing block extends into the first opening so that the first inclined surface contacts the second inclined surface.

[0006] Specifically, an end plate is arranged outside the end of the first guiding channel away from the clamping jaw. The elastic component includes a connecting member that passes through the end plate from the outside and is fixedly connected to the first sliding member, and an elastic member sleeved on the connecting member and pressing against the outside of the end plate.

[0007] Specifically, the connecting member is a bolt, the elastic member is a spring, there are multiple connecting members, and correspondingly, there are also multiple springs.

[0008] Specifically, one end of the first guiding member close to the clamping jaw is provided with a second opening. The longitudinal section of the second opening is in a horizontally U-shaped form. The horizontally U-shaped opening communicates with the first guiding channel. Both the top and the bottom of the horizontally U-shaped opening are provided with clamping grooves. The width of the clamping grooves matches the width of the first sliding member.

[0021] Referring to Figure 1 、 Figure 2 , a riveting device provided by an embodiment of the present application is disposed on a motor production line and is used for riveting a motor housing. It includes: two riveting tool assemblies 10 oppositely arranged on both sides of the riveting station 1, and further includes two clamping assemblies 20 oppositely arranged on both sides of the riveting station 1. The two clamping assemblies 20 are located below the two riveting tool assemblies 10. After clamping and fixing the motor housing through the two clamping assemblies 20, riveting is then performed through the riveting tool assemblies 10. Specifically, please refer to Figure 3 and Figure 4 , the clamping assembly 20 includes a jaw 21 arranged along a first direction, a first slider 22 that moves back and forth along the first direction and is fixed to the jaw 21, a first guide member 23 arranged along the first direction for the first slider 22 to slide, an elastic assembly 24 provided at one end of the first guide member 23 away from the jaw 21 and connected to the first slider 22, and a first driving member 25 arranged along a second direction. The first direction is perpendicular to the second direction. The driving shaft of the first driving member 25 is provided with a push block 26. The push block 26 extends into the first guide member 23 and contacts the first slider 22. The end of the push block 26 has a first inclined surface 261, and the first slider 22 has a second inclined surface 221. The first inclined surface 261 contacts the second inclined surface 221.

[0022] In the embodiment of the present application, the first direction is the linear direction where the two jaws 21 are located, and the second direction is perpendicular to the first direction, that is, the first driving member 25 is located on one side of the jaws 21. When the first driving member 25 is activated, its drive shaft drives the pushing block 26 to move along the second direction. When the pushing block 26 moves within the first guiding member 23, it acts on the second inclined surface 221 of the first sliding member 22 through the first inclined surface 261, causing the first sliding member 22 to move along the second direction, that is, driving the jaws 21 to move towards the motor housing on the riveting station 1 for clamping. At this time, the elastic component 24 is compressed; when the drive shaft of the first driving member 25 drives the pushing block 26 to retract, the first inclined surface 261 of the pushing block 26 slowly disengages from the second inclined surface 221 of the first sliding member 22, and the elastic component 24 of the first sliding member 22 pulls the first sliding member 22 to move back under the action of the restoring force and pulls the jaws 21 to release the motor housing. In this embodiment, the first driving member 25 and the pushing block 26 are in different directions from the first sliding member 22 and the jaws 21. The pushing block 26 and the first sliding member 22 are pushed by the inclined surface, and the transmission force between the two is greater than the frictional force between the two. Also, because they are not on the same straight line, self-locking is achieved, that is, it will not reverse and retreat in the clamping direction, and the clamping effect is better, avoiding the defect in the prior art that the transmission force and the clamping force are on the same straight line and are reversed and retreated, resulting in unstable clamping.

[0023] Specifically, referring to Figure 3 、 Figure 4 , in this embodiment, the first guiding member 23 is generally in the shape of a cube block, and it is provided with a first guiding channel 231 penetrating along the first direction and a second guiding channel 232 penetrating along the second direction. The first guiding channel 231 and the second guiding channel 232 are in communication. The first sliding member 22 is slidably disposed in the first guiding channel 231, and the pushing block 26 is disposed in the second guiding channel 232. Among them, the second guiding channel 232 is disposed close to the edge of the first guiding member 23 body on one side. The end surface of the first sliding member 22 close to the pushing block 26 is provided with a first opening 222, and the second inclined surface 221 is disposed in the first opening 222. The pushing block 26 extends from the second guiding channel 232 into the first opening 222 so that the first inclined surface 261 is in contact with the second inclined surface 221.

[0024] In this embodiment, an end plate 27 is provided on the outer side of one end of the first guiding channel 231 away from the clamping jaw 21, and the end plate 27 is fixed to the end face of the first guiding member 23 by fasteners such as screws (not shown in the figure). The elastic component 24 is arranged on the outer side of the end plate 27. Specifically, the elastic component 24 includes a plurality of connecting members 241 and a plurality of elastic members 242. One elastic member 242 is sleeved on each connecting member 241. The elastic member 242 passes through the end plate 27 from the outside and is fixedly connected to the first sliding member 22. The elastic member 242 is located on the outer side of the end plate 27. One end of the elastic member 242 abuts against the end face of the connecting member 241, and the other end of the elastic member 242 abuts against the outer wall of the end plate 27. In this embodiment, the connecting member 241 is a bolt, the elastic member 242 is a spring, there are four connecting members 241, and there are also four corresponding springs. When the pushing block 26 pushes the first sliding member 22 towards the riveting station 1, the connecting member 241 and the spring move accordingly. At the same time, the spring is restricted by the end plate 27 and is compressed on the outer side of the end plate 27. At this time, the spring has an elastic restoring force. When the pushing block 26 retracts, the elastic restoring force of the spring pulls the connecting member 241 and the first sliding member 22 to retract, that is, to release the motor housing.

[0025] Further, in this embodiment, a second opening 233 is provided at one end of the first guiding member 23 close to the clamping jaw 21. The longitudinal section of the second opening 233 is in a horizontal U shape. The horizontal U-shaped opening communicates with the first guiding channel 231. Card slots 234 are provided at both the top and the bottom of the horizontal U-shaped opening. The width of the card slot 234 matches the width of the first sliding member 22. The top and the bottom of the first sliding member 22 are clamped in the card slots 234. By providing the card slots 234 at the top and the bottom of the U-shaped opening, the first sliding member 22 can be exactly clamped in the card slots 234. The card slots 234 play a limiting role on the first sliding member 22, so that it does not deviate during sliding.

[0026] In this embodiment, in order to better connect the clamping jaw 21 and the first sliding member 22 into a whole, a third opening 223 is provided at one end of the first sliding member 22 close to the clamping jaw 21. The end of the clamping jaw 21 extends into and is fixed in the third opening 223. As Figure 4 shown, the third opening 223 is located on the side of the first sliding member 22. The end of the clamping jaw 21 is filled in the third opening 223 and is connected by fasteners such as screws.

[0027] Referring to Figure 1 and Figure 2 , two riveting tool assemblies 10 are respectively arranged above the clamping assembly 20. Each riveting tool assembly 10 includes a second driving member (not shown in the figure), a connecting assembly 11 connected to the second driving member, and a riveting tool 12 arranged at the end of the connecting assembly 11. The second driving member is a cylinder, and the cylinder drives the connecting assembly 11 and the riveting tool 12 to move to rivet the motor housing on the riveting station 1.

[0028] In this embodiment, the connecting component 11 includes a second guiding member 111 fixed to the top of the first guiding member 23 and a second sliding member (not labeled in the figure) movably disposed within the second guiding member 111. One end of the second sliding member is connected to the output end of the second driving member, and the other end of the second sliding member is connected to the riveting tool 12.

[0029] Further, referring to Figure 1 , in this embodiment, a light source 30 is further provided on the periphery of the riveting station 1, a lifting device 40 is provided above the riveting station 1, and two detecting devices 50 for detecting the motor housing after riveting are oppositely arranged. The lifting device 40 provided above the riveting station 1 is used to place the motor housing before riveting on the riveting station 1, and take out the motor housing after riveting is completed. At this time, the light source 30 irradiates the motor housing to facilitate the two detecting devices 50 to take pictures and detect the motor housing. Specifically, there are four light sources 30, which are evenly distributed around the riveting station 1. In this way, the light irradiated on the motor housing is ensured to be uniform and bright.

[0030] In this embodiment, a dust shield 60 for blocking dust is further provided on the periphery of the riveting station 1 to prevent the dust of the motor housing from spreading everywhere during the riveting process. At the same time, a dust suction device (not shown in the figure) for adsorbing dust is provided at the bottom of the riveting station 1, and a bendable dust blowing pipe 70 is further provided on the periphery of the riveting station 1. The dust shield 60, the dust suction device and the dust blowing pipe 70 are all for facilitating the treatment of dust.

[0031] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered within the protection scope of the present application.
