TECHNICAL FIELD

[0001] The present application relates to the technical field of press riveting, in particular to a press riveting machine for processing various types of workpieces. BACKGROUND

[0002] The existing press riveting machine (also known as a rivet machine, a spin riveting machine, a riveting machine, a riveting machine, etc.) is a new type of riveting equipment developed according to the cold rolling principle, which refers to a mechanical equipment that can rivet objects with rivets. It solves the problem that some sheet metal parts cannot be directly fitted on the ordinary inclined steel mechanical press riveting machine after bending.

[0003] Press riveting is a riveting method that uses the static pressure generated by a press riveting machine to upset the rivet rod to form a head. The riveting part of press riveting has the characteristics of good surface quality, small deformation, and high connection strength. Therefore, in actual operation, press riveting is preferred as long as the structure and process are allowed.

[0004] The existing rivet press riveting machine generally first punches the workpiece, and then the operator holds the rivet, especially when processing some round plastic parts or round iron parts with a thin bottom. Punching and riveting need to be completed by different instruments, which greatly affects the production efficiency of the factory. In the case of manual holding, aligning the rivet hole and the rivet is a very challenging work for eyesight and physical strength. Manual hole alignment is prone to errors, which can cause damage to the workpiece, reduce the yield of the workpiece, and cause eye damage when the operator works on the rivet hole for a long time. It is also easy to cause more serious personal injuries in mechanical accidents. SUMMARY

[0005] To solve the problems in the prior art, the present application provides a press riveting machine for processing various types of workpieces.

[0019] The beneficial effects of this invention are:

[0020] (1) The riveting machine for processing various types of workpieces described in this invention adopts a hole changing component and a distance adjusting component. When drilling, the chuck mechanism needs to be pulled to slide away from the rotating mechanism, and then the position of the rotating mechanism is adjusted so that the rotating shaft slides inside the first locking groove to find a suitable position. Then, the pin is inserted into the positioning hole and passes through the insertion hole to fix the rotating shaft so that the rotating shaft slides inside the first locking groove and then the rotating shaft is fixed. Finally, the chuck mechanism is re-clamped with the rotating mechanism, and then the workpiece is clamped with the clamping mechanism. Drilling can be performed by a multi-functional pressure head. After drilling, the pin feeding component is used to rivet the workpiece. The two steps of drilling and riveting can be performed on the same machine, which makes the operation convenient and fast and improves the efficiency of production and processing.

[0021] (2) The riveting machine for processing various types of workpieces described in this invention employs a rotating mechanism and a clamping mechanism. When the workpiece is placed in the center of the turntable, the extension of the second electric push rod is controlled, which pushes the clamping slider connected to it to slide into the second locking groove. Since the first slide rod and the second slide rod are slidably connected to the sliding support rod limiting position inside the support rod groove, the clamping slider will drive the first slide rod and the second slide rod slidably connected inside to slide and gradually approach the workpiece. The first slide rod and the second slide rod will drive the clamping slider connected to their other ends to approach the workpiece, and then clamp the workpiece in the center of the turntable and close it. The power to the second electric push rod is turned off, and the clamping mechanism has an automatic centering function. Then, the pressure cylinder is used to apply pressure to the multi-functional pressure head to open the workpiece. Then, the T-shaped block is pressed and the spring is squeezed, so that the T-shaped block slides down along the rotating groove and the top of the T-shaped block is no longer locked in the groove. Then, the user rotates the turntable, so that the T-shaped block rotates along the outer wall of the turntable until it rotates to the next groove. When it rotates to the next groove, the T-shaped block is pushed by the spring and locks back into the groove. At this time, the workpiece can continue to be opened. The opening can be automatic and does not require manual handling, which improves the safety performance of the machine and reduces the risk of injury to the user.

[0022] (3) The riveting machine for processing various types of workpieces described in this invention adopts a chuck mechanism. When the T-shaped chuck is pressed, the spring is squeezed, causing the T-shaped chuck to rotate along the rotating groove and causing the top of the T-shaped chuck to no longer be stuck in the groove. Then the user rotates the turntable, causing the T-shaped chuck to rotate along the outer wall of the turntable until it rotates to the next groove. When it rotates to the next groove, the T-shaped chuck is pushed by the spring and re-clamps into the groove. It can accurately limit the turntable and make the rivet hole aligned with the semi-circular ring. The rivet can smoothly enter the rivet hole for the next processing step. It can accurately position the machine during hole opening and riveting, improve the processing accuracy, and eliminate the need for the operator to use their eyes for positioning processing.

[0035] This invention provides a riveting machine for processing various types of workpieces, solving the problems of existing riveting machines that basically require drilling holes in the workpiece before riveting, and the tendency for errors to occur when manually holding the machine, which can easily damage the workpiece, reduce its quality, and cause personal injury when staring at the riveting hole for a long time.

[0036] The technical solution in this invention is to solve the above-mentioned technical problems. The overall idea is as follows: Existing riveting machines are basically used to process pre-drilled parts, which requires drilling the holes separately, which is not conducive to improving production efficiency. Therefore, this invention adds the function of drilling holes. In addition, existing riveting machines generally require manual hand-held riveting, which greatly affects efficiency. Therefore, this invention uses an automatic clamping and positioning clamping mechanism to solve the problems of drilling and hole alignment, and can accurately position the drilling position to achieve riveting, reducing manual hole alignment errors.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] like Figures 1-10 As shown, the riveting machine for processing various types of workpieces according to the present invention includes a pressure cylinder 1, an operating table 5, a multi-functional pressure head 6, a C-shaped support frame 7, and a fixing block 8. The C-shaped support frame 7 is fixed to the top center of the operating table 5. The pressure cylinder 1 is fixed to the top of the C-shaped support frame 7 by screws. The multi-functional pressure head 6 is threaded to the bottom end of the pressure cylinder 1, which can perform the functions of pressing holes and riveting. The fixing block 8 is fixed to the bottom of the C-shaped support frame 7. The nail feeding component 2 is installed on the top of the fixing block 8, which can perform the function of automatic nail feeding. The distance adjustment component 4 is installed on one side of the bottom of the C-shaped support frame 7, which can adjust and adapt to the processing requirements of various types of workpieces. The bottom of the distance adjustment component 4 is fixed to the operating table 5, and one end of the distance adjustment component 4 is connected to the hole changing component 3, which can adjust the processing requirements of various hole distances. The hole changing component 3 is located above one end of the nail feeding component 2.

[0039] The adjustable distance assembly 4 includes an adjustable distance slide rail 41, a fixed rod 45, a first engaging slide groove 46, and a chuck mechanism 47. The fixed rod 45 is welded to the upper surface of the operating table 5, and the adjustable distance slide rail 41 is fixed to the top of the fixed rod 45. The upper end face of the adjustable distance slide rail 41 is provided with a first engaging slide groove 46. The inside of the first engaging slide groove 46 is inverted T-shaped, and the hole changing assembly 3 is slidably engaged in the inside of the first engaging slide groove 46. The end of the first engaging slide groove 46 away from the C-shaped support 7 is slidably engaged with the chuck mechanism 47, and the chuck mechanism 47 is connected to the hole changing assembly 3.

[0040] The hole-changing assembly 3 includes a rotating mechanism 31, a clamping mechanism 32, a rotating shaft 33, and an insertion hole 34. The rotating shaft 33 is slidably engaged inside the first engaging groove 46. A ring is provided at the bottom of the rotating shaft 33, which is mainly engaged with the bottom of the inverted T-shaped first engaging groove 46 by the ring, and the rotating shaft 33 is restricted. An insertion hole 34 is provided in the middle of the rotating shaft 33, and the rotating mechanism 31 is rotatably connected to the top of the rotating shaft 33. The clamping mechanism 32 is connected to the top of the rotating mechanism 31, and the workpiece 9 is clamped in the middle of the clamping mechanism 32. The workpiece 9 is located in the middle of the rotating mechanism 31.

[0041] Specifically, the adjustable distance assembly 4 also includes positioning holes 42, pins 43 and pins 44. The adjustable distance slide rail 41 is provided with a number of positioning holes 42 evenly on one end near the C-shaped support 7, and the positioning holes 42 are all connected through the first snap-fit ​​slide groove 46. The pins 43 are inserted into one of the positioning holes 42 and the pins 43 are inserted into the insertion hole 34 in the middle of the rotating shaft 33. One end of the pins 43 is fixed by the pins 44.

[0042] In this embodiment of the invention, the adjusting component 4 is mainly used to adjust the required opening position of the workpiece 9. When the opening position needs to be adjusted, the pin 43 is first pulled out. At this time, the rotating shaft 33 is not restricted, and the ring at the bottom of the rotating shaft 33 slides into the first locking groove 46, which can prevent the rotating shaft 33 from disengaging from the first locking groove 46. Then, the chuck mechanism 47 needs to be pulled to slide away from the rotating mechanism 31, and then the position of the rotating mechanism 31 is adjusted. Pulling the rotating mechanism 31 drives the rotating shaft 33, so that the rotating shaft 33 is in the first locking groove 46. 6. Slide the internal part to find a suitable position, then insert the pin 43 into the positioning hole 42 and pass it through the insertion hole 34 to fix the rotating shaft 33 so that the rotating shaft 33 is fixed inside the first snap-fit ​​groove 46. Finally, make the chuck mechanism 47 re-clamp the rotating mechanism 31, and then use the clamping mechanism 32 to clamp the workpiece 9. The multi-functional pressure head 6 can be used to open the hole. After the hole is opened, it can be riveted with the pin feeding assembly 2. The two steps of drilling and riveting can be performed on the same machine, which makes the operation convenient and fast and improves the efficiency of production and processing.

[0043] Specifically, the rotating mechanism 31 includes a turntable 311, a slot 312, a nail outlet hole 313, a second locking groove 314, and a support rod groove 315. The turntable 311 is rotatably connected to the top of the rotating shaft 33, and four rows of nail outlet holes 313 are symmetrically opened in the middle of the turntable 311. A second locking groove 314 and a support rod groove 315 are sequentially opened between two adjacent rows of nail outlet holes 313. A clamping mechanism 32 is connected between the second locking groove 314 and the support rod groove 315. Several sets of slots 312 are circumferentially opened on the outer side wall of the rotating shaft 33. The positions of the slots 312 correspond to each row of nail outlet holes 313, and the chuck mechanism 47 is engaged in the slot 312 near the first locking groove 46.

[0044] Specifically, the nail holes 313 are arranged in a cross shape, and the spacing between two adjacent nail holes 313 in the same row is equal. The two opposing rows of nail holes 313 are on the same straight line as the adjustable slide rail 41, and the support rod slide groove 315 is located in the middle of two adjacent second locking slide grooves 314.

[0045] Specifically, the clamping mechanism 32 includes a clamping slider 321, a first slide rod 322, a second slide rod 323, a sliding support rod 324, and a second electric push rod 325. The clamping slider 321 is slidably engaged with the second engaging groove 314, and the first slide rod 322 is slidably inserted into one side of the clamping slider 321, while the second slide rod 323 is slidably inserted into the other side of the clamping slider 321. The first slide rod 322 is located above the second slide rod 323, and the first slide rod 322 and the second slide rod 323 are perpendicular to each other. The first slide rod 322 and the second slide rod 323 are respectively slidably inserted into the interior of the adjacent clamping slider 321. The middle of the first slide rod 322 and the second slide rod 323 are both fixed with a sliding support rod 324. The sliding support rod 324 is slidably connected to the inside of the support rod groove 315. The clamping slider 321 near the nail feeding assembly 2 and the outer side of the corresponding clamping slider 321 are both fixed with a second electric push rod 325. The tail of the second electric push rod 325 is fixed to the outer wall of the turntable 311.

[0046] In this embodiment of the invention, when the workpiece 9 is placed in the middle of the turntable 311, the second electric push rod 325 is extended, which pushes the clamping slider 321 connected to it to slide into the second locking groove 314. Since the first slide rod 322 and the second slide rod 323 are slidably connected to the sliding support rod 324 inside the support rod groove 315, the clamping slider 321 will drive the first slide rod 322 and the second slide rod 323 slidably connected inside it to slide and gradually approach the workpiece 9. The first slide rod 322 and the second slide rod 323 will drive the clamping slider 321 connected to its other end to approach the workpiece 9. Then the workpiece 9 is clamped in the middle of the turntable 311. When the second electric push rod 325 extends, it pushes the clamping slider 321 connected to it to the second locking groove 314 to slide into the second locking groove 314. When the clamping mechanism 32 is extended to its maximum length, it can clamp and fix the workpiece 9. Then, the pressure cylinder 1 applies pressure to the multi-functional pressure head 6 to open the workpiece 9. Then, the T-shaped locking block 471 is pressed and the spring 474 is squeezed, so that the T-shaped locking block 471 rotates along the rotating groove 473 and drives the top of the T-shaped locking block 471 to disengage from the slot 312. Then, the user rotates the turntable 311, so that the T-shaped locking block 471 rotates along the outer wall of the turntable 311 until it rotates to the next slot 312. When the T-shaped locking block 471 is pushed by the spring 474, it re-locks into the slot 312. At this time, the workpiece 9 continues to be opened. The opening can be automatic and does not require manual handling, which improves the safety performance of the machine.

[0047] Specifically, the nail feeding assembly 2 includes a semi-circular ring 21, a first electric push rod 22, a nail rail 23, rivets 24, and a nail pressing assembly 25. The first electric push rod 22 is fixedly inserted into the top of the fixing block 8, and a semi-circular ring 21 is fixed to the top of the first electric push rod 22. The top of the semi-circular ring 21 contacts and supports the bottom surface of the turntable 311, and the semi-circular ring 21 is located directly below the multi-functional pressing head 6. A nail rail 23 is welded to one side of the semi-circular ring 21. Several rivets 24 are arranged inside the nail rail 23, and a nail pressing assembly 25 is provided at the curved part of the nail rail 23.

[0048] Specifically, the rivet assembly 25 includes a drive motor 251, a mounting plate 252, and a cross blade 253. The mounting plate 252 is fixed to one side of the curved part of the rivet rail 23, and the drive motor 251 is fixed to the bottom of the mounting plate 252. The output shaft of the drive motor 251 passes through the mounting plate 252 and is fixedly connected to the cross blade 253. The cross blade 253 is located above the mounting plate 252, and the blade on one side of the cross blade 253 is located between two rivets 24.

[0049] In this embodiment of the invention, after the rivet hole of the workpiece 9 is opened, a riveting step is performed. The power supply of the rivet assembly 25 is turned on, and the drive motor 251 is controlled to rotate, driving the cross blade 253 to rotate. The cross blade 253 pushes the rivet 24 downward, and the rivet 24 transmits power and pushes the nearest rivet 24 into the semi-circular ring 21. At this time, the pressure cylinder 1 is controlled to apply pressure to the multi-functional pressure head 6, and the power supply of the first electric push rod 22 is turned on at the same time. The telescopic axis of the first electric push rod 22 pushes the rivet 24 upward, pushing the rivet 24 into the rivet outlet hole 313 on the turntable 311. The multi-functional pressure head 6 can rivet the rivet 24 into the rivet hole of the workpiece 9, and then it can be re-riveted. During the re-drilling process, the turntable 311 continues to rotate. The turntable 311 can be limited by the chuck mechanism 47. After the drilling and riveting of the workpiece 9 are completed, the second electric push rod 325 is shortened. The second electric push rod 325 pulls the clamping slider 321 to slide outward along the second snap-fit ​​groove 314. This can drive the first slide rod 322 and the second slide rod 323 away from the workpiece 9, and drive the remaining clamping sliders 321 to slide outward along the second snap-fit ​​groove 314. Then the workpiece 9 can be taken out and the next workpiece 9 can be processed. The use of the riveting assembly 2 improves the efficiency of production and processing and also increases the safety performance of the machine.

[0050] Specifically, the chuck mechanism 47 includes a T-shaped locking block 471, a sliding base 472, a rotating groove 473, and a spring 474. The sliding base 472 is slidably locked inside the first locking groove 46, and the sliding base 472 matches the inverted T-shaped first locking groove 46. A rotating groove 473 is provided on the side of the sliding base 472 away from the changing hole assembly 3. The T-shaped locking block 471 is slidably connected inside the rotating groove 473. A spring 474 is installed on the side of the rotating groove 473 away from the T-shaped locking block 471. The top of the spring 474 is fixed to the T-shaped locking block 471, and the bottom of the spring 474 is fixed to the rotating groove 473. The top of the T-shaped locking block 471 is locked into the locking groove 312.

[0051] In this embodiment of the invention, when the T-shaped locking block 471 is pressed, the spring 474 is squeezed, causing the T-shaped locking block 471 to slide down along the rotating groove 473 and causing the top of the T-shaped locking block 471 to no longer be locked in the groove 312. Then, the user rotates the turntable 311, causing the T-shaped locking block 471 to rotate along the outer wall of the turntable 311 until it rotates to the next groove 312. At this time, the T-shaped locking block 471 is pushed by the spring 474 and re-locks into the groove 312, which can accurately limit the turntable 311 and make the nail hole 313 aligned with the semicircular ring 21, so that the rivet 24 can smoothly enter the rivet hole for the next processing step.

[0052] Specifically, metal spring pieces 10 are fixed on both sides of the bottom of the sliding base 472, and the sliding base 472 is slidably connected to the side walls of the first locking groove 46. When the sliding base 472 is pulled by hand, it can drive the T-shaped locking block 471, so that the chuck mechanism 47 slides to a position away from the turntable 311. Due to the presence of the metal spring pieces 10, the friction on both sides of the chuck mechanism 47 is increased, so that the chuck mechanism 47 is more stably locked inside the first locking groove 46.

[0053] Specifically, the diameter of the telescopic shaft of the first electric push rod 22 is equal to the inner diameter of the semicircular ring 21, so that the telescopic shaft of the first electric push rod 22 can smoothly push the rivet 24 to the rivet hole 313, and the distance between adjacent positioning holes 42 is equal to the distance between adjacent rivet holes 313 in the same row, so that when the turntable 311 slides inside the first locking groove 46 with the rotating shaft 33, any rivet hole 313 that is in the same straight line as the adjusting slide rail 41 can be aligned with the semicircular ring 21.

[0054] Working principle: In use, first perform the hole-making step. Adjust the appropriate hole position according to the workpiece 9. First, pull the sliding base 472 by hand, which will drive the T-shaped locking block 471, so that the chuck mechanism 47 slides away from the turntable 311. Due to the presence of the metal spring 10, the friction on both sides of the chuck mechanism 47 is increased, making the chuck mechanism 47 more stably locked inside the first locking groove 46. Then, remove the pin 44 and pull out the pin 43. Pull or push the turntable 311, which will drive the rotating shaft 33, so that the rotating shaft 33 slides inside the first locking groove 46. Find a suitable pin outlet hole 313 and align it with the inner ring of the semicircular ring 21. Then, insert the pin 43 into the positioning hole 42 and pass it through the insertion hole 34 to fix the rotating shaft 33. Then, push the sliding base 472 and drive the T-shaped locking block 471 to re-lock the locking groove 312. Then, place the workpiece 9 in the middle of the turntable 311 and control the extension of the second electric push rod 325 to push the clamping slider 321 connected to it to slide into the second locking groove 314. Due to the first sliding rod 322 and the second sliding rod 323, The sliding support rod 324, which is slidably connected inside the support rod groove 315, restricts the position, causing the clamping slider 321 to drive the first sliding rod 322 and the second sliding rod 323, which are slidably connected inside, to slide and gradually approach the workpiece 9. The first sliding rod 322 and the second sliding rod 323, in turn, drive the clamping slider 321 connected at their other ends toward the workpiece 9, thereby clamping the workpiece 9 in the middle of the turntable 311. When the second electric push rod 325 extends to its longest position, the clamping mechanism 32 can clamp and fix the workpiece 9. Then, the pressure cylinder 1 applies pressure to the multi-functional pressure head 6. The workpiece 9 is drilled, then the T-shaped locking block 471 is pressed and the spring 474 is squeezed, causing the T-shaped locking block 471 to slide down along the rotating groove 473 and the top of the T-shaped locking block 471 to disengage from the slot 312. Then the user rotates the turntable 311, causing the T-shaped locking block 471 to rotate along the outer wall of the turntable 311 until it rotates to the next slot 312. At this time, the T-shaped locking block 471 is pushed by the spring 474 and re-locks into the slot 312. At this time, the workpiece 9 continues to be drilled. The drilling can be automatic and does not require manual handling, which improves the safety performance of the machine.

[0055] After the rivet hole of the workpiece 9 is opened, the riveting step is performed. The power supply of the rivet assembly 25 is turned on, and the drive motor 251 is controlled to rotate, which drives the cross blade 253 to rotate. The cross blade 253 pushes the rivet 24 downward. The rivet 24 transmits power and pushes the nearest rivet 24 into the semi-circular ring 21. At this time, the pressure cylinder 1 is controlled to apply pressure to the multi-functional pressure head 6, and the power supply of the first electric push rod 22 is turned on at the same time. The telescopic axis of the first electric push rod 22 pushes the rivet 24 upward, pushing the rivet 24 into the rivet outlet hole 313 on the turntable 311. At this time, the multi-functional pressure head 6 can rivet the rivet 24 into the rivet hole of the workpiece 9. Then the steps of opening the hole can be repeated to continue rotating the turntable 311. The turntable 311 can be limited by the chuck mechanism 47. After the drilling and riveting of the workpiece 9 are completed, the second electric push rod 325 is shortened. At this time, the second electric push rod 325 pulls the clamping slider 321 to slide outward along the second locking groove 314, which can drive the first slide rod 322 and the second slide rod 323 away from the workpiece 9, and drive the remaining clamping sliders 321 to slide outward along the second locking groove 314. Then the workpiece 9 can be taken out and the next workpiece 9 can be processed. With the use of the clamping mechanism 32, the riveting machine does not require the operator to manually pick up the workpiece for riveting. It combines drilling and riveting, which improves work efficiency and increases the safety performance of the machine.
