Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, and in particular to a riveting machine that facilitates quick mold changes. Background Technology

[0002] A riveting machine is a specialized piece of equipment that uses mechanical or hydraulic / pneumatic power to apply pressure to riveted parts through a specific mold, causing plastic deformation to achieve a firm connection or fixation. Its core function is to complete the riveting process through pressure, eliminating the need for additional connecting parts (such as bolts and nuts) or welding, and directly achieving the connection between components through material deformation.

[0003] When changing molds, traditional riveting machines require loosening bolts one by one or using tools to adjust the clamps. This relies heavily on the operator's skills, and loose bolts or adjustment errors can easily lead to inaccurate mold positioning, affecting the riveting quality. Utility Model Content

[0004] The purpose of this invention is to provide a riveting machine that facilitates quick mold replacement. This device enables quick disassembly and replacement of molds, thus solving the problem of inconvenient quick disassembly and replacement of molds in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A riveting machine for easy and quick mold change includes a base, a support seat fixedly connected to the upper end of the base, a through-hole groove provided inside the support seat, a rotating seat rotatably connected inside the base, a plurality of grooves provided inside the rotating seat, a movable plate slidably connected inside the grooves, an electric push rod fixedly connected inside the base, and holes and slots respectively provided on the upper end of the base, the slots communicating with the holes and grooves; a bracket fixedly mounted on the upper end of the base, a hydraulic cylinder fixedly connected to the upper end of the bracket, a movable block slidably connected to the lower end of the bracket, the output end of the hydraulic cylinder fixedly connected to the upper end of the movable block, an installation groove provided on the lower end of the movable block, a plurality of square grooves provided on the side wall of the movable block, clamping blocks slidably connected inside the square grooves, a riveting mold slidably connected inside the installation groove, and the inner wall of the clamping block tightly fitting the side wall of the riveting mold.

[0007] Preferably, a spring is fixedly connected to the bottom of the groove, and the end of the spring is fixedly connected to the lower end of the movable plate.

[0008] Preferably, a reflector is fixedly connected inside the lower end of the movable plate, and a photoelectric sensor is fixedly connected inside the output end of the electric push rod.

[0009] Preferably, a motor is fixedly connected inside the base, and the output end of the motor is fixedly connected to the lower end of the rotator.

[0010] Preferably, the movable block has a ring block threadedly connected to its side wall, and a ring plate is fixedly connected to the lower end of the ring block, the ring plate cooperating with the clamping block.

[0011] Preferably, the inner walls on both sides of the square groove are provided with sliding grooves, and a slider is slidably connected inside the sliding groove. The end of the slider is fixedly connected to the side wall of the clamping block, and an elastic element is fixedly connected between the side wall of the slider and the inner wall of the sliding groove.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The operator only needs to put the rivet into the hole. The subsequent material distribution is completed by the rotation of the rotating base driven by the motor. When the reflector rotates with the rotating base to the photoelectric sensor, the intensity of the reflected light suddenly changes, triggering a signal. The controller immediately cuts off the motor current and stops the stepper motor using its self-locking function. The electric push rod pushes the rivet in the groove through the slot to the upper end of the support seat. The operator only needs to place the workpiece, and the rivet will automatically slide to the upper end of the support seat, thereby improving the efficiency of the workpiece riveting process.

[0014] 2. The operator manually rotates the ring block in the reverse direction. Through the threaded engagement, the ring block drives the ring plate to slide upward. After the ring plate disengages from the clamping block, the elastic element automatically contracts and pulls the slider, driving multiple clamping blocks to slide outward synchronously, releasing the clamping of the mold. After the new mold is slid into the mounting slot, the ring block is rotated in the forward direction, and the ring plate slides downward. Its inclined wall contacts the inclined wall of the clamping block and generates a radial force, pushing multiple clamping blocks to slide inward synchronously, tightly adhering to the side wall of the mold to complete the clamping, thus facilitating the quick disassembly and replacement of the riveting mold.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6A riveting machine for quick mold changing includes a base 001, a support seat 101 fixedly connected to the upper end of the base 001, a slot 102 penetrating inside the support seat 101, a rotating seat 103 rotatably connected inside the base 001, a plurality of grooves 104 penetrating inside the rotating seat 103, a movable plate 105 slidably connected inside the grooves 104, an electric push rod 109 fixedly connected inside the base 001, holes 111 and slots 112 respectively provided on the upper end of the base 001, the slots 112 communicating with the slots 102; and a bracket 002 fixedly mounted on the upper end of the base 001, a hydraulic cylinder 201 fixedly connected to the upper end of the bracket 002, and a slidably connected... The movable block 202 has its output end fixedly connected to the upper end of the hydraulic cylinder 201. The lower end of the movable block 202 has an installation groove 203, and its sidewall has multiple square grooves 204. Clamping blocks 205 are slidably connected inside the square grooves 204. A riveting die 211 is slidably connected inside the installation groove 203. The inner wall of the clamping block 205 is tightly fitted to the sidewall of the riveting die 211. The hydraulic cylinder 201 works in conjunction with an external hydraulic pump. When the operator places the rivet inside the hole 111, the rotary seat 103 rotates, and one of the grooves 104 rotates to below the hole 111. The rivet inside the hole 111 falls into one of the grooves 104, while the rivet is located inside the movable plate 105. At the top, the rotary seat 103 rotates, rotating the groove 104 carrying the rivet to below the slot 112. Simultaneously, the movable plate 105 carrying the rivet is positioned above the electric actuator 109. The output end of the electric actuator 109 then extends into the groove 104 and pushes the movable plate 105 upwards. The movable plate 105 pushes the rivet, sliding it through the slot 112 and groove 102 to the upper end of the support seat 101. At the same time, the output end of the electric actuator 109 remains horizontal with the upper end of the support seat 101. The operator then places the workpiece to be riveted on the upper end of the support seat 101, and the rivet slides into the riveting hole of the workpiece. The output end of the hydraulic cylinder 201 then pushes the movable block 202 downwards, causing the rivet to... The riveting die 211 presses down on the rivet to perform riveting processing on the workpiece. When the riveting die 211 needs to be replaced due to wear, multiple clamping blocks 205 slide outward to release the clamping of the riveting die 211. The riveting die 211 falls out of the mounting slot 203 under its own weight, allowing for quick removal. Subsequently, the operator slides the new riveting die 211 into the mounting slot 203. The multiple clamping blocks 205 slide inward, and the inner walls of the multiple clamping blocks 205 contact the side walls of the riveting die 211, clamping and fixing the riveting die 211 for quick installation. The inner walls of the clamping blocks 205 are provided with anti-slip textures.

[0024] A spring 106 is fixedly connected to the bottom of the groove 104. The end of the spring 106 is fixedly connected to the lower end of the movable plate 105. When the movable plate 105 is pushed, the spring 106 is pulled up. When the pushing force on the movable plate 105 disappears, the spring 106 contracts and pulls the movable plate 105 to slide.

[0025] A reflector 107 is fixedly connected to the lower end of the movable plate 105, and a photoelectric sensor 110 is fixedly connected to the output end of the electric push rod 109. The photoelectric sensor 110 is an E3Z-LS61 type reflective sensor. The rotary table 103 drives multiple movable plates 105 to rotate. When one of the reflectors 107 rotates above the photoelectric sensor 110, the reflected light is detected by the receiving end of the photoelectric sensor 110, triggering a signal, and the rotary table 103 stops rotating.

[0026] A motor 108 is fixedly connected inside the base 001. The output end of the motor 108 is fixedly connected to the lower end of the rotary table 103. The motor 108 is a 42BYGH40-1704A stepper motor with a self-locking structure. The output end of the motor 108 drives the rotary table 103 to rotate. A controller is fixedly connected inside the base 001. The controller is electrically connected to the motor 108, the photoelectric sensor 110 and the electric push rod 109 respectively.

[0027] The movable block 202 has a ring block 206 threadedly connected to its side wall. The lower end of the ring block 206 is fixedly connected to a ring plate 207. The ring plate 207 cooperates with the clamping block 205. The operator manually rotates the ring block 206. Through the threaded cooperation between the inner wall of the ring block 206 and the side wall of the movable block 202, the ring block 206 drives the ring plate 207 to slide up and down. The inner wall of the ring plate 207 is inclined, and the outer wall of the clamping block 205 is inclined. When the ring plate 207 slides down, its inclined wall contacts the inclined wall of the clamping block 205 and pushes the clamping block 205 to slide inward.

[0028] Both sides of the square groove 204 are provided with sliding grooves 208. A slider 209 is slidably connected inside the sliding groove 208. The end of the slider 209 is fixedly connected to the side wall of the clamping block 205. An elastic element 210 is fixedly connected between the side wall of the slider 209 and the inner wall of the sliding groove 208. When the clamping block 205 is pushed to slide, the clamping block 205 drives the slider 209 to slide, which stretches the elastic element 210. When the inner wall of the ring plate 207 is separated from the outer wall of the clamping block 205, the elastic element 210 contracts and pulls the slider 209 to slide, which causes the slider 209 to drive the clamping block 205 to slide back to its original position.

[0029] In this invention, the operator places the rivet inside the hole 111. The controller controls the motor 108 to operate, and the output of the motor 108 drives the rotating base 103 to rotate. As the rotating base 103 rotates, one of the grooves 104 rotates to below the hole 111, and the rivet inside the hole 111 falls into one of the grooves 104. At the same time, the rivet is located on the upper end of the movable plate 105 inside it. Subsequently, the rotating base 103 rotates, and when the reflector 107 rotates with the rotating base 103 to directly above the photoelectric sensor 110, the sudden change in the intensity of the reflected light triggers the sensor signal. After receiving the signal, the controller immediately cuts off the driving current of the motor 108 and uses the self-locking function of the stepper motor to achieve precise stopping, ensuring that the groove 104 is aligned with the slot 112, while the upper end supports... A movable plate 105 carrying rivets is positioned above an electric actuator 109. The controller then controls the electric actuator 109 to operate, with its output end extending into the groove 104 and pushing the movable plate 105 upward. The movable plate 105 pushes the rivet through the slot 112 and the groove 102 to the upper end of the support seat 101. At the same time, the output end of the electric actuator 109 remains horizontal with the upper end of the support seat 101. The operator then places the workpiece to be riveted on the upper end of the support seat 101, and the rivet slides into the riveting hole of the workpiece. The operator then activates the hydraulic cylinder 201, and the output end of the hydraulic cylinder 201 pushes the movable block 202 downward, causing the riveting die 211 to press the rivet, thereby performing riveting on the workpiece.

[0030] When the riveting die 211 needs to be replaced due to wear, the operator manually rotates the ring block 206 in the reverse direction. Through the threaded engagement between the inner wall of the ring block 206 and the side wall of the movable block 202, the ring block 206 causes the ring plate 207 to slide upwards. The inner wall of the ring plate 207 gradually disengages from the outer wall of the clamping block 205. The elastic element 210 contracts and pulls the slider 209 to slide, causing the slider 209 to drive the clamping block 205 to slide. Multiple clamping blocks 205 slide outwards, releasing the clamping of the riveting die 211. The riveting die 211 falls out of the mounting groove 203 under its own weight. 11. Quickly dismantle the mold, then slide the new riveting mold 211 into the mounting slot 203. The operator manually rotates the ring block 206 in the forward direction. Through the threaded engagement between the inner wall of the ring block 206 and the side wall of the movable block 202, the ring block 206 drives the ring plate 207 to slide downward. The inclined wall of the ring plate 207 contacts the inclined wall of the clamping block 205 and pushes the clamping block 205 to slide inward. The inner walls of multiple clamping blocks 205 contact the side wall of the riveting mold 211. The riveting mold 211 is clamped and fixed by multiple clamping blocks 205, and the riveting mold 211 is quickly installed.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
