DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 A hydraulic riveting device for hammer production in this embodiment includes a hydraulic riveting machine body 1, a workbench 2 in contact with the ground is provided on the lower side of the hydraulic riveting machine body 1, belt conveyor frames 3 are provided on the left and right sides of the workbench 2, a loading and unloading mechanism 4 for improving the loading and unloading efficiency of the hammer is provided on the left belt conveyor frame 3, and a clamping mechanism 5 for clamping the hammer is provided on the workbench 2.

[0028] It can be understood that the hammer is transported to the workbench 2 by the left-side belt conveyor 3, and the hammer head of the hammer is placed on the top of the left and right sides of the belt conveyor 3, and the hammer can be transported along the belts on the left and right sides; when the processed hammer rotates in front of the staff again, the staff can remove it and clamp the hammer on the upper surface of the right-side belt conveyor 3 to transport it to the next process.

[0029] In this embodiment, the cross-sectional shape of the workbench 2 is circular, and the lower surface of the workbench 2 is rotatably connected to a supporting base through a bearing. A placement groove is provided on the upper surface of the supporting base, and a rotating motor is fixed to the inner cavity of the placement groove. The output shaft of the rotating motor is fixedly connected to the center of the lower surface of the workbench 2. The rotating motor on the lower side of the workbench 2 is started, and the output shaft of the rotating motor rotates to drive the workbench 2 to rotate, thereby changing the angle of the hammer. When the hammer moves to the lower side of the hydraulic riveting machine body 1, the rotating motor will be in standby state, so that the hydraulic riveting machine body 1 will perform hydraulic processing on the rivet.

[0030] It should be noted that a control panel is externally connected to the right side of the supporting base, which can be used to control the start and stop of the rotating motor, and is equipped with an intelligent control system for controlling the start of the hydraulic riveting machine body 1 when the hammer moves to the lower side of the hydraulic riveting machine body 1.

[0031] See also Figure 2 In order to facilitate the loading and unloading operation of the hammer, the loading and unloading mechanism 4 in this embodiment includes a support plate 401 fixed to the left and right sides of the left belt conveyor frame 3, a hinge seat 402 is fixed on the front of the support plate 401, and the inner cavity of the hinge seat 402 is hingedly connected with a hinge block 403, and a torsion spring 404 is provided between the hinge seat 402 and the opposite side of the hinge block 403. When the limit of the baffle 405 is released, the torsion spring 404 can pull the baffle 405 back to the initial position, so that the baffle 405 One side of 5 is in contact with the frame of the belt conveyor frame 3, and the same baffle 405 is fixed to the front of the hinge blocks 403 on the left and right sides. The baffle 405 can block the hammer transported to the baffle 405 to prevent it from falling. When the staff is taking materials, they can turn the baffle 405 to the side away from the belt conveyor frame 3. At this time, the rotation of the baffle 405 drives the hinge block 403 to rotate in the inner cavity of the hinge seat 402 and causes the torsion spring 404 to deform.

[0032] A material collecting platform 406 in contact with the ground is provided on the front side of the left belt conveyor frame 3 and directly below the baffle plate 405. A buffer plate 407 is fixed to the inner cavity of the material collecting platform 406. The rotation of the baffle plate 405 allows the hammer at the baffle plate 405 to fall on the upper surface of the buffer plate 407 in the inner cavity of the material collecting platform 406 through the gap between the baffle plate 405 and the belt conveyor frame 3. A number of evenly distributed spring buffer rods 408 are fixed between the buffer plate 407 and the opposite side of the material collecting platform 406. When the hammer that falls on the upper surface of the buffer plate 407 contacts the buffer plate 407, an impact force is generated on the buffer plate 407, causing the buffer plate 407 to move downward, further causing the spring buffer rod 408 to compress and absorb and reduce the impact force, thereby preventing the hammer from being hit, and under the guidance of the material collecting platform 406, the hammer can move to the right end of the material collecting platform 406, so as to facilitate the staff to pick it up.

[0033] In this embodiment, the length of the baffle 405 in the horizontal direction is greater than the length of the belt conveyor frame 3 in the horizontal direction, and the two hinge blocks 403 are symmetrically distributed on the left and right sides of the vertical center axis of the baffle 405. The cross-sectional shape of the material collection table 406 is L-shaped, and the height of the left side of the material collection table 406 is greater than the height of the right side. A rubber pad is fixed to the inner wall of the material collection table 406.

[0034] It should be noted that the hammer is moved to a position convenient for workers to pick up and place under the conveyance of the belt conveyor frame 3, so that the workers can easily load and unload the hammer, and when the hammer is hydraulically riveted, the loading and unloading operations can be performed simultaneously, thereby improving the production efficiency of the hammer.

[0035] See also Figures 3 to 5 In order to improve the production efficiency of the hammer, the clamping mechanism 5 in this embodiment includes four positioning plates 501 fixed on the workbench 2, and the left and right ends of the upper surface of the positioning plates 501 are provided with first clamping holes 502, and the upper surface of the positioning plates 501 is provided with a hammer head placement plate 503, and the middle part of the upper surface of the hammer head placement plate 503 is provided with a through hole 504, and the middle part of the upper surface of the positioning plate 501 is fixed with a clamping rod 505, and the upper surface of the clamping rod 505 passes through the through hole 504 and extends to the inner cavity of the through hole 504, and the upper surface is provided with an arc extrusion groove 506, and the bottom of the rivet can be extruded and formed in the inner cavity of the arc extrusion groove 506, so that the hammer head and the handle of the hammer are fixed again by the rivet.

[0036] A connecting plate 507 is fixed on both sides of the positioning plate 501. A second clamping hole 508 is opened on the upper surface of the connecting plate 507. A fixing block 509 is provided on the upper surface of the connecting plate 507. A limiting rod 510 is fixed to the inner wall of the opposite side of the two fixing blocks 509. A movable rod 511 is slidably connected to the outer surface of the limiting rod 510. A return spring 512 is movably sleeved on the outer surface of the movable rod 511. A movable plate 513 is fixed on the opposite side of the two movable rods 511. A linkage rod 514 with one end penetrating and extending to the opposite side of the two fixing blocks 509 is fixed on the opposite side of the two movable plates 513. The two linkage rods 514 are fixed on the opposite side of the two fixing blocks 509. The two clamping plates 515 are fixed on the opposite sides of 14. The hammer head of the hammer is placed in the inner cavity of the hammer head placement plate 503, and then the handle of the hammer is pressed downward. The downward movement of the handle of the hammer will cause the two clamping plates 515 to be pressed to move away from each other, thereby causing the two linkage rods 514 to move away from each other. The movement of the two linkage rods 514 pushes the two movable plates 513 to move away from each other, thereby causing the movable rod 511 to move on the outer surface of the limiting rod 510, and the return spring 512 can be shortened by the provided partition, so that the distance between the two clamping plates 515 is increased, and the handle of the hammer can be moved to the opposite side of the two clamping plates 515.

[0037] In this embodiment, four positioning plates 501 are evenly distributed on the upper surface of the workbench 2, and the cross-sectional shape of the positioning plates 501 is T-shaped. The left and right ends of the lower surface of the hammer head placement plate 503 are fixedly connected to the positioning plate 501 by bolts passing through two first clamping holes 502, and the lower surface of the fixing block 509 is fixedly connected to the connecting plate 507 by bolts passing through two second clamping holes 508. The set first clamping holes 502 and second clamping holes 508 can replace hammer head placement plates 503 of different sizes according to the sizes of different hammers and adjust the position of the fixing block 509, thereby improving adaptability and flexibility.

[0038] Among them, partitions are fixed on the opposite sides of the front and rear side walls of the inner cavity of the fixed block 509, and the distance between the two partitions is smaller than the inner diameter of the return spring 512. Inner holes are opened on the opposite sides of the two fixed blocks 509, and the inner diameter of the inner hole is adapted to the outer diameter of the linkage rod 514. The cross-sectional shape of the top of the splint 515 is trapezoidal, and the cross-sectional shape of the bottom of the splint 515 is rectangular, and the two splints 515 are symmetrical about the Y axis.

[0039] It is understandable that the return spring 512 rebounds after being free of pressure and drives the movable plate 513 to move, thereby moving the movable rod 511 and the linkage rod 514, and further causing the two clamping plates 515 to move relative to each other, thereby clamping the handle of the hammer.

[0040] It should be noted that four processing positions are provided on the workbench 2, which further improves the riveting efficiency of the hammer. The provided clamping mechanism 5 can facilitate the workers to carry out the taking and placing operations on the hammer, thereby reducing the labor intensity of the workers.

[0041] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0042] The working principle of the above embodiment is:

[0043] (1) The hammer can be transported to the workbench 2 by the left belt conveyor 3, and the hammer head of the hammer can be placed on the top of the left and right sides of the belt conveyor 3. The hammer can be transported along the belts on the left and right sides. The baffle 405 can block the hammer transported to the baffle 405 to prevent it from falling. When the staff is taking materials, they can turn the baffle 405 to the side away from the belt conveyor 3. At this time, the rotation of the baffle 405 drives the hinge block 403 to rotate in the inner cavity of the hinge seat 402, and causes the torsion spring 404 to deform, so that the hammer at the baffle 405 can pass through the baffle 405 and the belt conveyor 3. The gap falls on the upper surface of the buffer plate 407 in the inner cavity of the material collection platform 406, and then the limit on the baffle 405 is released, and the torsion spring 404 can pull the baffle 405 back to the initial position, so that one side of the baffle 405 is in contact with the frame of the belt conveyor frame 3, and the hammer that falls on the upper surface of the buffer plate 407 will generate an impact force on the buffer plate 407 when it contacts the buffer plate 407, causing the buffer plate 407 to move downward, further causing the spring buffer rod 408 to compress and absorb and reduce the impact force, thereby preventing the hammer from being hit, and under the guidance of the material collection platform 406, the hammer can move to the right end of the material collection platform 406, so that it is convenient for the staff to take it.

[0044] (2) When the hydraulic riveting machine body 1 is used to press the rivet into the hammer, the hammer head of the hammer can be placed in the inner cavity of the hammer head placement plate 503, and then the handle of the hammer can be squeezed downward. The downward movement of the handle of the hammer will cause the two clamping plates 515 to move away from each other under pressure, thereby causing the two linkage rods 514 to move away from each other. The movement of the two linkage rods 514 pushes the two movable plates 513 to move away from each other, thereby causing the movable rod 511 to move on the outer surface of the limit rod 510, and the return spring 512 can be shortened by the provided partition, thereby increasing the distance between the two clamping plates 515, and the handle of the hammer can be moved to the opposite side of the two clamping plates 515. At this time, the return spring 512 rebounds after being unpressed and drives the movable plate 513 to move, thereby causing the movable rod 511 to move on the outer surface of the limit rod 510. The movable rod 511 and the linkage rod 514 move, thereby causing the two clamping plates 515 to move relative to each other, so that the handle of the hammer can be clamped, and then the rotating motor on the lower side of the workbench 2 is started, and the output shaft of the rotating motor rotates to drive the workbench 2 to rotate, thereby changing the angle of the hammer. When the hammer moves to the lower side of the hydraulic riveting machine body 1, the rotating motor will be in a standby state, so that the hydraulic riveting machine body 1 hydraulically processes the rivet, so that the bottom of the rivet can be extruded into shape in the inner cavity of the arc extrusion groove 506, so that the hammer head and the handle of the hammer are fixed again by the rivet. When the processed hammer rotates in front of the staff again, the staff can remove and clamp the hammer on the upper surface of the belt conveyor 3 on the right side to transport it to the next process.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
