Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve assembly technology, and more specifically, to an automatic riveting and demolding device for electromagnetic valves. Background Technology

[0002] The solenoid valve housing includes an outer shell and a cover plate mounted on the outer shell. The assembly structure between the outer shell and the cover plate can be achieved in various ways, such as by using threaded connectors, snap-fit, or riveting.

[0003] The existing technology can be referenced from Chinese Patent Publication No. CN208804299U, which discloses a patent entitled "Solenoid Valve Housing and its Riveting Fixture." The patent includes a fixed base, on which a clamping seat for clamping the solenoid valve housing is mounted, and a cylinder located above the clamping seat. A riveting mold is mounted on the piston rod of the cylinder. The bottom surface of the riveting mold has riveting blocks corresponding to the secondary grooves, used to bend the insert clips toward the corresponding insert grooves and press them to fix the cover plate. However, this riveting fixture still has certain drawbacks in use: it cannot fix the solenoid valve during riveting, which can easily cause the solenoid valve to shake or shift during riveting, resulting in substandard riveting effect. In addition, due to the deep riveting depth, it is difficult for the riveting head to come out, and the solenoid valve can easily move synchronously with it, causing difficulties for workers in unloading the material, thus its practicality is poor. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic riveting and demolding device for electromagnetic valves.

[0005] The objective of this utility model is achieved through the following technical solution: An automatic riveting and demolding device for a solenoid valve includes a frame, a support plate for supporting the solenoid valve on the frame, a positioning component for positioning the solenoid valve on the support plate, a riveting component above the support plate that can move vertically under the drive of a pressing component, the riveting component including at least a mounting base, a mounting plate fixed to the bottom of the mounting base, a riveting head mounted on the mounting plate, sliding shafts slidably mounted on both sides of the riveting head, and a floating plate fixed to the end of the sliding shafts; a spring sleeved on the sliding shaft, one end of the spring being mounted on the mounting plate and the other end being mounted on the floating plate; a bushing sleeved on the riveting head, the bushing being fixed to the floating plate.

[0006] Preferably, the riveting head includes at least a body and a through groove formed thereon, the diameter of the through groove being smaller than the diameter of the mounting hole on the solenoid valve, and the outer diameter of the body being larger than the diameter of the mounting hole.

[0007] Preferably, the pressing assembly includes an electric cylinder fixed on the frame, the cylinder shaft of the electric cylinder being connected to the pressing plate via an I-beam wheel, and the riveting assembly being mounted on the pressing plate; the mounting plate is also provided with a sliding sleeve around its perimeter, the sliding sleeve being fitted onto a matching sliding column, and the sliding column being fixed on the frame.

[0008] Preferably, a guide rail is fixed to the bottom of the pressing plate, a guide block adapted to the guide rail is provided on the guide rail, a guide plate is fixed on the guide block, and the mounting seat is fixed on the guide plate.

[0009] Preferably, a connecting seat is fixedly provided on the pressing plate, a telescopic cylinder is fixedly provided on the connecting seat, a connecting plate is fixedly provided on the cylinder shaft of the telescopic cylinder, and the guide plate is fixedly provided at the other end of the connecting plate.

[0012] Preferably, the frame is further provided with a bracket, and a CCD camera is fixed on the bracket, the CCD camera being located on one side or above the positioning component.

[0013] The beneficial effects of this utility model are mainly reflected in: 1. The design is ingenious. After the riveting head rivets the solenoid valve, during the process of the pressing component driving the riveting head to move upward, the floating plate, under the action of the spring, applies a reverse force to the solenoid valve, thereby separating the solenoid valve from the riveting head. This effectively solves the problem of the riveting head and the solenoid valve being difficult to separate and sticking together, improves the convenience of material unloading, and has a wide range of applicability.

[0014] 2. The support block and positioning plate work together to position the solenoid valve, preventing displacement or movement during riveting and maximizing the yield rate. Furthermore, this positioning structure is simple, convenient, stable, reliable, and easy to disassemble, replace, and maintain, greatly improving work efficiency.

[0015] 3. The setting of the riveting head can apply pressure to the solenoid valve near the assembly hole, changing its radial texture direction to an inclined or axial texture direction, reducing the material flow tendency, thereby achieving the best riveting effect, improving the quality after riveting, and facilitating mass production.

[0016] 4. The telescopic cylinder can realize the position adjustment of the riveting components and the quick switching between multiple components. This structure achieves high integration, reduces the space occupied, and at the same time, facilitates the processing of workpieces, reduces the process flow, simplifies the press-fitting process, and improves convenience.

[0017] 5. Electric cylinders are high-precision transmission devices that use electrical energy to drive linear motion. Compared with traditional hydraulic drives, they have lower noise levels and more stable operating accuracy. In addition, they also have advantages such as fast response and excellent accuracy.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, this utility model discloses an automatic riveting and demolding device for a solenoid valve, including a frame 1. The frame 1 is provided with a support plate 2 for supporting the solenoid valve 100. The support plate 2 can be fixed on the frame 1, or it can be slidably arranged on the frame 1 through the cooperation of a slide rail and a slider.

[0024] The support plate 2 is provided with a positioning assembly 3 for positioning the solenoid valve 100. The positioning assembly 3 includes at least a positioning plate 31 mirror-mounted on the support plate 2. One end of the positioning plate 31 has an inwardly recessed protrusion 32, and the other end has a support plate 33 fixed to the support plate 2. A positioning cylinder 34 is fixed on the support plate 33, and a support block 35 is fixed on the cylinder shaft of the positioning cylinder 34. The support block 35 can drive the solenoid valve 100 to abut against the protrusion 32. In the above, the support block 35 and the positioning plate 31 cooperate to position the solenoid valve, avoiding displacement or movement of the solenoid valve during riveting, and maximizing the yield rate. In addition, this positioning structure is simple, convenient, stable, reliable, easy to disassemble, replace, and maintain, greatly improving work efficiency.

[0025] A riveting assembly 4 is provided above the support plate 2. The riveting assembly 4 includes at least a mounting base 41. A mounting plate 42 is fixedly mounted on the bottom of the mounting base 41. A riveting head 43 is mounted on the mounting plate 42. Sliding shafts 44 are slidably provided on both sides of the riveting head 43. A floating plate 45 is fixedly mounted on the end side of the sliding shafts 44. A spring 46 is sleeved on the sliding shafts 44. One end of the spring 46 is mounted on the mounting plate 42, and the other end is mounted on the floating plate 45. A bushing 47 is sleeved on the riveting head 43 and fixedly mounted on the floating plate 45. After the riveting head 43 rivets the solenoid valve 100, during the process of the pressing assembly 5 driving the riveting head 43 upward, the floating plate 45, under the action of the spring 46, applies a reverse force to the solenoid valve 100, thereby separating the solenoid valve from the riveting head. This effectively solves the problem of the riveting head and the solenoid valve being difficult to separate and sticking together, improves the convenience of material unloading, and has wide applicability.

[0026] Furthermore, the riveting head 43 includes at least a body 431 and a through groove 432 formed thereon. The diameter of the through groove 432 is smaller than the diameter of the mounting hole 101 on the solenoid valve 100, and the outer diameter of the body 431 is larger than the diameter of the mounting hole 101. This ingenious design allows the riveting head 43 to apply pressure to the solenoid valve near the mounting hole, changing its radial texture direction to an inclined or axial texture direction, reducing material flow tendency, thereby achieving optimal riveting effect, improving the quality after riveting, and facilitating mass production.

[0027] In this application, the riveting assembly 4 can move vertically under the drive of the pressing assembly 5. Specifically, the pressing assembly 5 includes an electric cylinder 51 fixed on the frame 1. The cylinder shaft of the electric cylinder 51 is connected to the pressing plate 53 via an I-beam wheel. The riveting assembly 4 is mounted on the pressing plate 53. A sliding sleeve 54 is also provided around the mounting plate 53. The sliding sleeve 54 is fitted onto a matching sliding column 55, which is fixed to the frame 1. The aforementioned use of an electric cylinder is a high-precision transmission device that utilizes electrical energy to drive linear motion. Compared with traditional hydraulic drives, it has lower noise levels and more stable operating accuracy. In addition, it also has advantages such as rapid response and excellent accuracy.

[0028] A connecting seat 59 is fixedly mounted on the pressing plate 53, and a telescopic cylinder 591 is fixedly mounted on the connecting seat 59. A connecting plate 592 is fixedly mounted on the cylinder shaft of the telescopic cylinder 591, and a guide plate 58 is fixedly mounted on the other end of the connecting plate 592. A guide rail 56 is fixedly mounted on the bottom of the pressing plate 53, and a guide block 57 adapted to it is provided on the guide rail 56. The guide plate 58 is fixedly mounted on the guide block 57, and the mounting seat 41 is fixedly mounted on the guide plate 58. The telescopic cylinder 591 can realize the position adjustment of the riveting assembly 4 and the rapid switching between multiple assemblies. This structure achieves high integration, reduces the space occupied, and facilitates the processing of workpieces, reduces the process flow, simplifies the pressing process, and improves convenience. The above is a preferred embodiment of this utility model, in which two riveting assemblies 4 are installed on the guide plate 58. Of course, other components can also be set, such as welding components, pressing components, detection components, etc., all of which fall within the protection scope of this utility model.

[0029] In addition, a bracket 10 is fixed on the frame 1, and a CCD camera 6 is fixed on the bracket 10. The CCD camera is located on one side or above the positioning component 3. The CCD camera 6 includes at least an image sensor and an analog-to-digital converter (ADC). The image sensor is connected to the ADC, and the ADC has a communication interface. The image sensor converts external light signals into analog signals, and the ADC converts the analog signals into digital signals and transmits them to the processor. The CCD camera 6 used in this invention can meet the illumination requirements of industrial manufacturing environments and has high sensitivity. The system uses a communication interface for data transmission, which can effectively prevent interference from other signals and improve the stability of data transmission. At the same time, the CCD camera 6 includes an optical lens connected to the body, and the image sensor and ADC are located inside the body. The optical lens gathers external light onto the image sensor, which is beneficial for the system to acquire clear images.

[0030] The working process of this utility model is briefly described below: The robotic arm clamps and transfers the solenoid valve between the positioning plates 31. At this time, the cylinder shaft of the positioning cylinder 34 extends and drives the solenoid valve 100 to move forward through the support block 35 until it abuts against the protrusion 32.

[0031] The electric cylinder 51 is activated and moves along the pressing plate 53 until the riveting head 43 completes the riveting of the solenoid valve. After the riveting is completed, the electric cylinder 51 is reset. During the reset process, the floating plate 45 applies a reverse force to the solenoid valve 100 under the action of the spring 46, thereby causing the solenoid valve to separate from the riveting head.

[0032] If other processes are required to process the solenoid valve in this solution, the switching and adjustment between components can be achieved by moving the guide plate 58 through the telescopic cylinder, which greatly improves convenience.
