Description

Technical Field

[0001] The present invention relates to the field of mechanical design, in particular to a positive and negative riveting device. Background Art

[0002] The description in this section merely provides background information related to the present disclosure and may not constitute prior art.

[0003] The slide rail includes an outer rail and an inner rail installed in the outer rail. The inner rail can slide relative to the outer rail. The outer rail is installed on an object through a slide rail seat, such as a slide rail in a drawer. The outer rail is installed on the drawer frame through a slide rail seat. Therefore, one of the steps in processing the slide rail is to fix the outer rail to the slide rail seat. This connection method is usually through rivets, and the rivets include positive rivets and reverse rivets. According to the actual application scenario, some slide rails need to be installed with positive rivets and reverse rivets, and the existing riveting equipment can only be positive riveted or reverse riveted. When the slide rail needs both positive riveting and reverse riveting, it is usually necessary to manually turn the slide rail over after completing the positive riveting, and then reverse rivet the slide rail. However, the manual turning process is not only time-consuming and labor-intensive, affecting the production rhythm, but also prone to defective products. Therefore, it is urgently necessary to invent a device that can complete positive and reverse riveting in one go without turning it over.

DETAILED DESCRIPTION

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] It should be noted that, in the description of the present invention, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0051] like Figure 1 The figure shows the forward and reverse riveting device of the present application, which can complete the forward and reverse riveting of the slide rail 10 in the device without manual flipping. The forward and reverse riveting device includes an X-axis track 300, a Y-axis track disposed on the X-axis track 300 and capable of sliding along the X-axis track 300, a lifting assembly disposed on the Y-axis track and capable of sliding along the Y-axis track, a C-shaped frame assembly 400 disposed on the lifting assembly and capable of rising and falling, and a dividing plate assembly 200, on which the slide rail 10 tooling 100 is disposed.

[0052] like Figure 2 As shown, the slide rail 10 tool 100 of the present application is shown. When processing the slide rail 10 , the slide rail 10 is placed on the slide rail 10 tool 100 .

[0053] In the present application, the slide rail 10 tooling 100 includes a tooling plate 101 and two rows of support members 102 provided on the tooling plate 101 , and one slide rail 10 can be placed on each row of support members 102 .

[0054] like Figure 3-8 The figure shows the slide rail 10 of the present application. The slide rail 10 includes an inner rail 11, an outer rail 13, and a slide rail base. The inner rail 11 and the outer rail 13 are slidably connected, and the outer rail 13 is fixedly connected to the slide rail base 10 via a positive rivet 18 and a reverse rivet 17. The positive and reverse riveting equipment of the present application is used to press the positive rivet 18 and the reverse rivet 17 to securely connect the outer rail 13 to the slide rail base 10.

[0055] like Figure 7 and 8 As shown, a slide rail 10 includes two slide rail 10 seats, which are respectively arranged at the two ends of the outer rail 13. The slide rail 10 seat at the first end of the outer rail 13 is fixedly connected to the outer rail 13 via a positive rivet 18 and a reverse rivet 17, and the slide rail 10 seat at the second end of the outer rail 13 is fixedly connected to the outer rail 13 via two reverse rivets 17. The tail of the positive rivet 18 passes through the slide rail 10 seat and extends downward.

[0056] The inner rail 11 can slide on the outer rail 13. When the inner rail 11 slides to the first end of the outer rail 13, the rivet at the second end for connecting the outer rail 13 and the sliding seat is exposed. At this time, the rivet at the second end can be press-riveted. When the inner rail 11 slides to the second end of the outer rail 13, the rivet at the first end for connecting the outer rail 13 and the sliding seat is exposed. At this time, the rivet at the first end can be press-riveted.

[0057] like Figure 9-11 As shown, the support member 102 is provided with a plurality of through holes extending vertically therethrough. When the slide rail 10 is mounted on the support member 102 , the rivets are located just above the through holes. A support column 103 is mounted in the through holes, and the support column 103 can move up and down along the through holes.

[0058] A concave ring 104 is formed on the inner wall of the through hole, and a convex ring 1032 is formed on the outer wall of the support column 103 . The convex ring 1032 can move up and down in the concave ring 104 , and the up and down position of the support column 103 is limited by the concave ring 104 .

[0059] A support spring 1031 is also installed in the through hole. The support spring 1031 is sleeved on the support column 103. The upper end of the support spring 1031 presses against the top of the concave ring 104 of the through hole, and the lower end of the support spring 1031 presses against the convex ring 1032.

[0060] When an upward pressure is applied to the support column 103 , the support column 103 can overcome the elastic force of the support spring 1031 and move upward, thereby press-riveting the reverse rivet 17 or supporting the positive rivet 18 .

[0061] A handle is provided at each end of the tooling plate 101 for lifting the slide rail 10 tooling 100 .

[0062] In one embodiment, each support member 102 has two through holes, each row has two support members 102 , and the four through holes of each row of support members 102 are located on the same straight line, corresponding to the four rivets of one slide rail 10 .

[0063] like Figure 3-6 12-15, the cross section of the inner rail 11 is in the shape of a Chinese character "F", and has two side walls. The lower ends of the side walls of the inner rail 11 are bent outward and upward to form a first bending portion 111, and a bending groove is formed in the first bending portion 111. The two side walls of the inner rail 11 are both equipped with an unlocking member and an elastic rod 15, and the two unlocking members are arranged opposite to each other.

[0064] Two first holes are defined along the sidewall of the inner rail 11, extending along the length of the slide rail 10. The ends of the elastic rod 15 extend from the inside outward through the first holes. A third hole and multiple fourth holes are located between the two first holes in the sidewall of the inner rail 11, with the fourth holes located below the third holes. The unlocking member includes a main body, an unlocking head 141 disposed on the main body, and a first tooth portion 143 disposed below the main body. The main body of the unlocking member is located inside the inner rail 11, with the unlocking head 141 extending through the third holes, and the multiple teeth of the first tooth portion 143 extending through the fourth holes. The main body of the unlocking member also includes a hook portion 142, which is hooked onto the elastic rod 15, and the elastic rod 15 applies an upward elastic force to the unlocking member.

[0065] The outer rail 13 has a bottom wall and side walls on either side of the bottom wall. The side walls of the outer rail 13 bend inward and downward to form a second bent portion 131. A second bent groove is formed in the second bent portion 131. When the outer rail 13 and the inner rail 11 are assembled, the first bent portion 111 of the inner rail 11 is inserted into the second bent groove of the outer rail 13, and the second bent portion 131 of the outer rail 13 is inserted into the first bent groove of the inner rail 11.

[0066] The edge of the second bent portion 131 of the outer rail 13 is a tooth-like structure, which is the second tooth portion 132. The teeth of the second tooth portion 132 are arranged along the length direction of the slide rail 10. When the outer rail 13 and the inner rail 11 are installed, the first tooth portion 143 of the unlocking member is inserted into the second tooth portion 132 of the outer rail 13. The first tooth portion 143 and the second tooth portion 132 are staggered with each other, which plays a limiting role. At this time, the outer rail 13 and the inner rail 11 cannot slide against each other.

[0067] When the unlocking member receives a downward pressing force, the unlocking member overcomes the elastic force of the elastic rod 15 and moves downward, and the first tooth portion 143 disengages from the second tooth portion 132 . At this time, the inner rail 11 can slide relative to the outer rail 13 .

[0068] The first bend 111 of the inner rail 11 is also fixedly mounted with an intermediate slider 12. A plurality of ball bearings 121 are mounted on the bottom and outer sidewalls of the intermediate slider 12. When the outer rail 13 and the inner rail 11 are mounted, the ball bearings 121 at the bottom of the intermediate slider 12 abut against the bottom wall of the outer rail 13, while the ball bearings 121 on the outer sidewalls of the intermediate slider 12 abut against the inner sidewalls of the outer rail 13. The intermediate rail 10 not only limits the relative movement between the inner rail 11 and the outer rail 13 to the length of the rail 10, but also reduces friction between the inner rail 11 and the outer rail 13, making the relative sliding of the inner rail 11 and the outer rail 13 smoother.

[0069] In order to prevent the unlocking piece from being accidentally pressed, an arched baffle is also provided on the inner rail 11, and the unlocking head 141 is located under the arched baffle. The arched baffle blocks the upper side and the front and rear sides of the unlocking head 141. When it is necessary to press the unlocking head 141, it is necessary to reach into the left and right sides of the arched baffle before pressing the unlocking head 141 downward.

[0070] like Figure 16 As shown, the forward and reverse riveting device of the present application further includes an unlocking component 500 , which is used to press the unlocking piece to unlock the slide rail 10 .

[0071] The unlocking assembly 500 includes a clamping cylinder 503 , two clamping jaws 504 that can be opened and closed under the drive of the clamping cylinder 503 , an unlocking upper and lower cylinder 501 for driving the clamping cylinder 503 to move up and down, and an unlocking middle cylinder 502 .

[0072] The working process of the unlocking component 500 is as follows: the unlocking middle cylinder 502 extends, the unlocking upper and lower cylinders 501 are pressed down to the middle position, the clamping cylinder 503 opens, and the two clamping claws 504 are controlled to be inserted into the two arched baffles respectively, the unlocking middle cylinder 502 retracts, the unlocking upper and lower cylinders 501 are pressed down, and the clamp presses the unlocking part to the bottom to complete the unlocking of the slide rail 10.

[0073] like Figure 17 As shown, the dividing plate assembly 200 of the present application includes a dividing plate 201 and a dividing plate drive motor 202 for driving the dividing plate to rotate. The dividing plate 201 has two workstations, and a baffle 203 is provided between the two workstations. A slide rail 10 tooling 100 can be provided on each workstation.

[0074] like Figure 18-21 As shown, the lifting assembly includes a frame 701 and a lifting rail vertically arranged on the frame 701.

[0075] The C-frame assembly 400 includes a C-frame 401, which includes side walls on both sides. A lifting plate 702 is provided between the two side walls of the C-frame 401. The two sides of the lifting plate 702 are fixed to the two side walls of the C-frame 401. The lifting plate 702 is slidably mounted on a lifting track. The lifting assembly also includes a lifting cylinder 703. The lifting cylinder 703 is used to drive the lifting plate 702 to move up and down along the lifting track.

[0076] The C-frame assembly 400 further includes an upper punch 403 and a lower punch 404 mounted on the C-frame 401 , and a booster cylinder 402 for driving the upper punch 403 to move up and down.

[0077] The C-frame assembly 400 further includes an upper mounting block 405 and a lower mounting block 409 . The upper mounting block 405 is fixedly connected to the two side walls of the C-frame 401 on both sides, and the lower mounting block 409 is fixedly connected to the two side walls of the C-frame 401 on both sides.

[0078] The booster cylinder 402 controls the vertical movement of the upper punch 403 via an output rod 406. This output rod 406 passes through the upper mounting block 405. The output rod 406 has a non-circular cross-section and is restrained by the upper mounting block 405, limiting its vertical movement. In a preferred embodiment, the output rod has a square cross-section. The lower punch 404 is mounted on a lower mounting block 409.

[0079] The C-frame assembly also includes a stopper 407, which is fixedly connected to the output rod 406 and located above the upper mounting block 405. This stopper 407 is used to limit the vertical position of the output rod 406. When the stopper 407 contacts the top of the C-frame 401, the upper punch 403 is in the uppermost position. When the stopper 407 contacts the upper mounting block 405, the upper punch 403 is in the lowermost position. The upper punch 403 and the lower punch 404 are arranged in a corresponding vertical relationship.

[0080] The lifting assembly further includes a support plate 704 , and the support plate 704 is used to support the indexing plate 201 .

[0081] The unlocking assembly 500 is installed on the C-frame 401. A clamping cylinder 408 is also installed on the unlocking assembly. The clamping cylinder 408 controls the up and down movement of the clamping head to clamp the slide rail 10 when processing the slide rail 10 to prevent the slide rail 10 from moving.

[0082] The forward and reverse riveting device of the present application further includes an X-axis motor 301 for driving the Y-axis track to slide along the X-axis track 300 and a Y-axis motor 601 for driving the lifting assembly to slide along the Y-axis track.

[0083] The working principle of the positive and negative riveting equipment in this application is as follows:

[0084] The slide rail 10 to be processed is placed on the slide rail 10 tooling 100, with two slide rails 10 placed on each slide rail 10 tooling 100. The slide rail 10 tooling 100 is placed on the dividing plate 201. There are two workstations on the dividing plate 201. When one of the workstations is in the processing state, the other workstation is used to pick up and place parts. When the slide rail 10 is processed, the dividing plate drive motor 202 drives the dividing plate 201 to rotate 180 degrees, and the other workstation is moved to the processing position. The processed slide rail 10 is removed and a new slide rail 10 to be processed is placed.

[0085] (1) Processing of the first end:

[0086] The indexing plate 201 rotates, causing the slide rail 10 to be processed to move between the upper punch 403 and the lower punch 404. The X-axis motor 301 and the Y-axis motor 601 adjust the position of the lifting assembly. The lifting cylinder 703 adjusts the upper and lower positions of the C-frame 401 so that the positive rivet 18 is located between the upper punch 403 and the lower punch 404. The clamping cylinder 408 drives the clamping head to press down, pressing against the slide rail 10 from above. The support plate 704 is supported on the lower surface of the indexing plate 201. The lower punch 404 presses against the support column 103 corresponding to the positive rivet 18. The upper punch 403 is pressed down by the booster cylinder 402 to complete the press riveting of the positive rivet 18 and complete the positive riveting.

[0087] Driven by the X-axis motor 301, the upper punch 403 and the lower punch 404 move to the position of the reverse rivet 17 at the first end, the booster cylinder 402 drives the upper punch 403 to press the reverse rivet 17, and the lifting cylinder 703 drives the C-frame 401 to move upward, so that the lower punch 404 presses the support column 103. Driven by the lower punch 404, the support column 103 presses the reverse rivet 17 to complete the reverse riveting.

[0088] The slide rail 10 fixture 100 has two slide rails 10 arranged in parallel. After the first end of one slide rail 10 is processed, the first end of the other slide rail 10 is processed in the same way.

[0089] (2) Unlocking the slide rail 10

[0090] When the first ends of the two slide rails 10 on the slide rail 10 fixture 100 are processed, the inner rail 11 needs to be moved to the first end to expose the rivets at the second ends of the slide rails 10 for easier processing.

[0091] The unlocking process is as follows: driven by the X-axis motor 301, the unlocking assembly 500 moves above the unlocking member, the unlocking center cylinder 502 extends, and the unlocking upper and lower movement control jaw cylinder 503 moves downward to the center position. The jaw cylinder 503 drives the two jaws 504 to insert into the arched blocks of the two slide rails 10. The unlocking center cylinder 502 retracts, and the unlocking upper and lower cylinders 501 press down, and the clamping head presses the unlocking member to the bottom, completing the unlocking of the slide rails 10. The X-axis motor 301 continues to operate, causing the C-frame 401 to move. The unlocking assembly 500 mounted on the C-frame 401 drives the inner rail 11 to move to the first end, exposing the rivet at the second end of the slide rail 10. Then, the unlocking upper and lower cylinders 501 drive the jaw cylinder 503 upward to the center position, and the jaw cylinder 503 drives the two jaws 504 to separate from the arched blocks. At this point, the slide rails 10 are locked, and the unlocking upper and lower cylinders 501 move upward.

[0092] (3) Processing of the second end

[0093] In one embodiment, the second end of the slide rail 10 is provided with two reverse rivets 17 .

[0094] The X-axis motor 301 and the Y-axis motor 601 adjust the position of the lifting assembly. The lifting cylinder 703 adjusts the vertical position of the C-frame 401 so that one of the second end counter-rivets 17 is positioned between the upper punch 403 and the lower punch 404. The pressing cylinder 408 drives the pressing head downward, pressing against the slide rail 10 from above. The boost cylinder 402 drives the upper punch 403 to press against the counter-rivet 17. The lifting cylinder 703 drives the C-frame 401 upward, causing the lower punch 404 to press against the support column 103. Driven by the lower punch 404, the support column 103 presses against the counter-rivet 17, completing the reverse riveting. The remaining counter-rivets 17 are processed in the same manner.

[0095] When the processing of the slide rail 10 of one slide rail 10 fixture 100 is completed, the indexing plate driving motor 202 drives the indexing plate 201 to rotate 180 degrees, so that the slide rail 10 fixture 100 of another station is in the processing position.
