Description

Technical Field

[0001] The invention relates to the field of metal riveting, in particular to a riveting machine. Background Art

[0002] A riveting machine is a mechanical device used for metal processing. It is mainly used to press fasteners such as rivets, nuts, bolts, etc. into metal plates or other metal structural parts to achieve fixed connections. This connection method is called riveting. It is a cold riveting process that does not require heating and therefore does not affect the properties of the metal material.

[0003] The principle is to press fasteners such as rivets into preset holes in metal plates through mechanical pressure, and use the deformation of the rivets to achieve a firm connection with the plates. However, in existing riveting machines, an additional feeding device is usually required to feed them, and when riveting, the plates need to be manually placed in the riveting area before riveting, which can easily cause deviations in the riveting position of the plates, and during the riveting process, the riveting machine can easily press on people's hands, causing danger.

[0004] With the development of science and technology, technicians in related fields have also made a lot of optimizations on the riveting machine to solve some of the above-mentioned problems. In order to make a more accurate comparison, a Chinese patent with publication number CN213104292U discloses a riveting machine.

[0036] The following combination Figures 1 to 8 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0037] The embodiment of the present application discloses a riveting machine, which is explained as follows: the riveting machine is mainly used in the process of pressing rivets into a workpiece by riveting. In terms of technical effect, the rivets can be stored by a storage device, and the storage device can cooperate with the riveting device. After the riveting device completes one riveting operation, the storage device can feed materials synchronously, eliminating the trouble of manual feeding; especially at the riveting position of the riveting device, the application of sensors can prevent the worker's hands from being placed on the surface of the workpiece, causing the riveting device to press the rivets on the hands and cause damage to the human body.

[0038] Example 1: Reference Figure 1 and Figure 2As shown, it includes a base plate 1, a sleeve 10, a rotating shaft 11, a support plate 12, a transverse groove 13, a transverse block 14 and an adjusting unit 2. A sleeve 10 is arranged on the base plate 1, and a rotating shaft 11 is rotatably arranged inside the sleeve 10. A support plate 12 is arranged on the upper end of the rotating shaft 11. The sleeve 10 can limit the rotating shaft 11 so that the rotating shaft 11 can rotate inside the sleeve 10, and the rotating shaft 11 can also drive the supporting plate 12 to rotate synchronously when rotating; a transverse groove 13 is opened at the end of the support plate 12, and a transverse block 14 is slidably arranged in the transverse groove 13. The adjusting unit 2 for changing the position of the workpiece is arranged on the transverse block 14, and the transverse block 14 can slide in the left and right directions inside the transverse groove 13 under the limiting guide, and the transverse block 14 can drive the adjusting unit 2 to move when moving, so as to change the lateral position of the adjusting unit 2.

[0039] Continue to refer to Figure 2 As shown, the adjusting unit 2 is used to change the position of the workpiece; specifically, the adjusting unit 2 includes a first screw rod 20, a longitudinal plate 21, a longitudinal groove 22, a longitudinal movement block 23, a second screw rod 24, a rectangular plate 25 and a clamping member 3, the first screw rod 20 is rotatably arranged on the inner walls on both sides of the transverse groove 13, the middle part of the first screw rod 20 is threadedly connected to the transverse movement block 14, and a longitudinal plate 21 is also arranged on the upper end of the transverse movement block 14. When the first screw rod 20 rotates, it can drive the transverse movement block 14 threadedly connected thereto to reciprocate in the left and right directions, and one end of the first screw rod 20 passes through the outer wall of the support plate 12 for connecting to an external drive motor, so that the external drive motor can drive it to rotate.

[0040] A longitudinal groove 22 is provided on the longitudinal plate 21, and a longitudinal movement block 23 is slidably arranged in the longitudinal groove 22. The longitudinal movement block 23 can move in the front-to-rear direction inside the longitudinal groove 22 under the limit guidance of the longitudinal groove 22; a second screw rod 24 is rotatably arranged on the inner walls on both sides of the longitudinal groove 22, and the middle part of the second screw rod 24 is threadedly connected to the longitudinal movement block 23. Similarly, one end of the second screw rod 24 passes through the corresponding outer wall of the longitudinal plate 21 for connecting to an external drive motor to provide it with rotational force. When the second screw rod 24 rotates, it can drive the longitudinal movement block 23 threadedly connected to it to move back and forth in the front-to-rear direction.

[0041] A rectangular plate 25 is also provided at the upper end of the longitudinal movement block 23, and a clamping member 3 for clamping the workpiece is provided on the rectangular plate 25. Therefore, the longitudinal movement block 23 can drive the rectangular plate 25 to move longitudinally in the front-to-back direction, and the longitudinal movement block 23 can be indirectly driven by the transverse movement block 14 to move laterally in the left-to-right direction, which indirectly enables the rectangular plate 25 to move synchronously in the left-to-right and front-to-back directions, so that the clamping member 3 can drive the workpiece to adjust its position in the transverse and longitudinal directions.

[0042] The “external drive motor” mentioned in the above implementation process is a prior art, and its purpose is to drive the corresponding first screw rod 20 and second screw rod 24 to rotate, so it will not be described in detail in this implementation process.

[0043] Reference Figure 3 As shown, the clamping member 3 for clamping the workpiece; specifically, the clamping member 3 includes a circular groove 30, a spring pull rod 31, a clamping plate 32 and a toggle rod 33. Several circular grooves 30 are opened at the four corners of the rectangular plate 25. The spring pull rod 31 is installed in the circular groove 30. The spring pull rod 31 can be installed in the circular groove 30 to reduce the height between the spring pull rod 31 and the upper end of the rectangular plate 25; the telescopic end of the spring pull rod 31 is rotatably sleeved with a clamping plate 32 located outside the circular groove 30, and the upper end of the clamping plate 32 is also provided with a toggle rod 33 The clamping plate 32 can be rotated on the telescopic end of the spring pull rod 31, and the toggle rod 33 is used to facilitate manual toggle of the clamping plate 32 for rotation. Before riveting, the workpiece is first placed on the upper end of the rectangular plate 25, and then the telescopic end of the clamping plate 32 and the spring pull rod 31 are indirectly pulled up by the toggle rod 33, and then the clamping plate 32 is rotated to the upper end of the workpiece, and then the clamping plate 32 is released so that the clamping plate 32 clamps the upper surface of the workpiece under the drive of the spring pull rod 31, thereby preventing the workpiece from being displaced and thus deviating during the riveting process.

[0044] A rubber pad (not shown in the figure) is also provided at one end of the clamping plate 32 facing the rectangular plate 25. The rubber pad is used to increase the friction between the clamping plate 32 and the workpiece to ensure that the workpiece will not be displaced during the riveting process.

[0045] After the workpiece is riveted, the clamping plate 32 no longer clamps the upper end of the workpiece by moving the lever 33 again.

[0046] Continue to refer to Figure 1 , Figure 4 and Figure 5 As shown, a strip plate 40 is also provided on one side of the bottom plate 1, and a top plate 41 corresponding to the bottom plate 1 is provided at the other end of the strip plate 40, and a riveting unit 4 is provided on the top plate 41; specifically, the riveting unit 4 includes a strip plate 40, a top plate 41, a hydraulic cylinder 42, a driving shaft 43, a limiting groove 44, a support rod 45, an arc plate 46, a distance sensor 47 and a driving spring 48, and the hydraulic cylinder 42 is provided at one end of the top plate 41, and the bottom plate 1 can support the hydraulic cylinder 42 through the strip plate 40 and the top plate 41.

[0047] The telescopic end of the hydraulic cylinder 42 passes through the other end of the base plate 1 and is provided with a driving shaft 43. The hydraulic cylinder 42 can drive the driving shaft 43 to move in the up and down directions; a limiting groove 44 is provided on the outer side of the driving shaft 43, and a support rod 45 is slidably provided in the limiting groove 44. Arc plates 46 are provided at both ends of the support rod 45. The support rod 45 can move in the up and down directions under the limiting guide of the corresponding limiting groove 44, and the arc plate 46 can move in the up and down directions through the corresponding support rod 45.

[0048] The end of the arc plate 46 facing the rectangular plate 25 is provided with several distance sensors 47 evenly distributed along its extension section, and a push spring 48 is also provided between the support rod 45 and the inner wall of the limit groove 44. The distance sensor 47 can detect how far the bottom of the arc plate 46 is from the surface of the workpiece. In the initial state, the push spring can drive the arc plate 46 to always be located at the lower end of the corresponding limit groove 44 through the corresponding support rod 45. Only when the arc plate 46 is in close contact with the surface of the workpiece can the support rod 45 be indirectly able to slide upward in the limit groove 44 and drive the corresponding push spring 48 to be compressed.

[0049] The “distance sensor 47 ” mentioned in the above implementation process is a well-known technology, and its function is to detect the distance between the arc plate 46 and the workpiece, so it will not be described in detail in this embodiment.

[0050] Continue to refer to Figure 5 As shown, an escapement 5 for escaping the rivet is also provided between the arc plates 46; specifically, the escapement 5 includes a sliding groove 50, a sliding plate 51, an arc strip 52, a ring 53, a spring rod 54, an escapement block 55, a riveting shaft 56, a reset spring 57 and a structural groove 58. The sliding groove 50 is provided at one end of the arc plate 46, and a sliding plate 51 is slidably provided in the sliding groove 50. The other end of the sliding plate 51 is provided with an arc strip 52, and a ring 53 is provided between the arc strips 52. The sliding plate 51 can drive the arc strip 52 to move in the up and down directions under the limit of the corresponding sliding groove 50, and the ring 53 can move in the up and down directions through the cooperation of the arc strip 52, the sliding plate 51 and the sliding groove 50.

[0051] Symmetrically distributed push spring rods 54 are provided on the inner wall of the circular ring 53, and an escapement block 55 is provided at the telescopic end of the push spring rod 54. When there is a rivet at the lower end of the circular ring 53, the circular ring 53 is driven to move downward by an external driving force, which can drive the escapement block 55 to contact the upper end of the rivet. When moving downward again, the escapement block 55 can reversely drive the telescopic end of the push spring rod 54 to contract until the escapement block 55 completes the clamping of the rivet.

[0052] The lower end of the pushing shaft 43 is also provided with a riveting shaft 56 with one end located on the inner wall of the circular ring 53, and a reset spring 57 is arranged between the sliding plate 51 and the inner wall of the sliding groove 50. The telescopic end of the hydraulic cylinder 42 can drive the riveting shaft 56 to move in the up and down directions through the pushing shaft 43, and the reset spring 57 can drive the circular ring 53 to be located at the lower end of the sliding groove 50 through the sliding plate 51 and the arc plate 46 in the initial state.

[0053] A structural groove 58 corresponding to the outer side of the rivet is formed on one side of the escapement block 55. The structural groove 58 allows the inner wall of the escapement block 55 to fit more closely with the outer side of the rivet to prevent the rivet from falling off.

[0054] When the hydraulic cylinder 42 indirectly drives the arc plate 46 to move downward, the distance sensor 47 at the lower end of the arc plate 46 will detect the distance between the arc plate 46 and the workpiece in real time. If a human hand appears on the workpiece at this time, the distance detected by the distance sensor 47 will suddenly change. At this time, the operation of the hydraulic cylinder 42 can be stopped to avoid harm to the human body. When the arc plate 46 contacts the upper end of the workpiece, the ring 53 also contacts the upper end of the workpiece. At this time, if a rivet is clamped between the escapement blocks 55, the bottom of the rivet will also contact the upper end of the workpiece. At this time, the pushing shaft 43 continues to drive the rivet pressing shaft 56 to move downward, and pushes the escapement block 55 to cancel the clamping of the rivet. At the same time, the rivet pressing shaft 56 synchronously presses the rivet into the workpiece.

[0055] Reference Figure 6 and Figure 7 As shown, a loading unit 6 for storing rivets is also provided on one side of the strip plate 40; specifically, the loading unit 6 includes a strip frame 60, a placement plate 61, a circular through groove 62, a push plate 63, an elastic spring 64, a cylinder 65, an L-shaped plate 66, a receiving plate 67, a receiving groove 68 and a limit ring 69. The strip frame 60 is arranged on one side of the strip plate 40, and symmetrically distributed placement plates 61 are arranged on the inner walls on both sides of the strip frame 60, and a gap is left between the two placement plates 61. A circular through groove 62 is commonly provided at one end of the placement plates 61. Rivets can be placed between the strip frames 60, and the heads of the rivets will be stuck in the upper ends of the placement plates 61, and the vertical sections thereof will be located in the gaps between the placement plates 61, and the rivets can be detached from the strip frame 60 and the placement plates 61 through the circular through groove 62.

[0056] A push plate 63 is slidably arranged between the strip frame 60 and the placement plate 61 , and an elastic spring 64 is arranged between the push plate 63 and the strip plate 40 . The push plate 63 is pushed by the elastic spring 64 to move toward the circular through groove 62 , and simultaneously pushes the rivet to move.

[0057] A cylinder 65 is also provided on one side of the strip plate 40 through a cylinder seat, and an L-shaped plate 66 is provided at the pushing end of the cylinder 65, which is tightly attached to the lower ends of the strip frame 60 and the placement plate 61. A receiving plate 67 corresponding to the lower end of the ring 53 is provided at one end of the L-shaped plate 66 away from the cylinder 65. The cylinder 65 can drive the L-shaped plate 66 and the receiving plate 67 to move.

[0058] A receiving groove 68 is provided on the receiving plate 67, and a limiting ring 69 is provided on the inner wall of the receiving groove 68. In the initial state, since the receiving groove 68 corresponds to the circular groove, a rivet will be pushed by the pushing plate 63 and fall into the receiving groove 68, and the head of the rivet is located on the limiting ring 69. Then the cylinder 65 indirectly pushes the receiving plate 67 to move toward the direction of the riveting unit 4. During this process, the receiving groove 68 no longer corresponds to the circular through groove 62, but is blocked by the L-shaped plate 66 and the outer side of the receiving plate 67. Therefore, the rivet in the bar frame 60 does not move. When the receiving groove 68 corresponds to the escapement 5, the hydraulic cylinder 42 indirectly drives the escapement 5 to clamp the screw in the receiving groove 68. Then the hydraulic cylinder 42 drives the escapement 5 to move upward for a distance, and the cylinder 65 indirectly drives the receiving plate 67 to move to the initial position. Finally, the hydraulic cylinder 42 can indirectly rivet the rivet into the workpiece through the escapement 5.

[0059] Example 2: Reference Figure 8 As shown, on the basis of the first embodiment, in order to prevent the rotating shaft 11 from accidentally rotating in the sleeve 10 when the workpiece is riveted, a clamping assembly 7 for limiting the rotating shaft 11 is provided in the sleeve 10; specifically, the clamping assembly 7 includes a clamping groove 70, a clamping block 71, a tightening spring 72 and a resisting groove 73, the clamping groove 70 is provided in the sleeve 10, a clamping block 71 is slidably provided in the clamping groove 70, a tightening spring 72 is provided between the clamping block 71 and the clamping groove 70, and a plurality of clamping blocks 72 are provided on the outside of the rotating shaft 11. The retaining members 77 are arranged on the cam face of the locking cam 71 and the retaining members 78 are arranged on the cam face of the locking cam 71. When the retaining members 77 are in a state of being pushed against the locking cam 71 by the retaining spring 72, the retaining members 78 are in a state of being pushed against the locking cam 71 by the retaining spring 72.

[0060] During operation: First, place the workpiece on the rectangular plate 25, and then clamp and fix the workpiece by the clamping member 3 to prevent the workpiece from being displaced during riveting.

[0061] Step 2: Then place the rivet in the feeding unit 6, start the riveting unit 4, and clamp the rivet discharged by the feeding unit 6 through the escapement 5, and then rivet the rivet to the workpiece through the cooperation of the riveting unit 4.

[0062] Step 3: During riveting, the adjusting unit 2 can indirectly drive the workpiece to change its position horizontally and vertically through the clamping member 3, so that after being clamped, the workpiece can be riveted at various places by changing its position by itself, and the rotation angle of the workpiece can be indirectly adjusted by rotating the support plate 12 through the cooperation of the clamping assembly 7, thereby further improving the applicability of the present invention.

[0063] Step 4: After riveting is completed, the workpiece is released from the support plate 12 by using the clamping member 3 .

[0064] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
