[0002] In the field of engineering machinery, oil cylinders are usually used to drive various parts to achieve complex movements of mechanisms such as lifting, telescoping and tilting. The oil cylinder seat mainly provides fixation and support for the oil cylinder, so that the oil cylinder maintains balance and stability during operation; at the same time, the oil cylinder seat can also protect the oil cylinder from external vibration and impact, thereby extending the service life of the equipment. Therefore, the accuracy of the size of the oil cylinder seat directly affects the safety and stability of the operation of the oil cylinder. At present, the oil cylinder seat is usually riveted manually, and manual riveting has a certain dependence on the skills and proficiency of the operator. This is because the appropriate force and angle need to be mastered during the riveting process to ensure that the rivet is fully embedded and connected to the parts. Insufficient skills or negligence may cause dimensional deviations, resulting in reduced riveting quality, or even failure to connect parts correctly; manual riveting takes a long time, the labor intensity of the operator is high, and the efficiency is low; after riveting, in some cases, positioning welding may be required to increase the stability and strength of the connection. Fumes will be generated during welding, and the generated fumes will be inhaled by the operator, affecting health. Utility Model Content

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the riveting tool of the utility model, the first clamping member 112 and the second clamping member 115 of the clamping assembly 11 move toward each other to clamp the workpiece, and at the same time, the pressing member 122 of the clamping assembly 12 approaches the workpiece and presses the workpiece, the clamping assembly 11 and the pressing assembly 12 jointly clamp and position the workpiece, and can adapt to workpieces of different models, thereby improving the application scope of the riveting tool and having strong versatility; the riveting tool has a high degree of automation, and the installation and positioning are rapid and accurate, which reduces the dimensional deviation caused by manual operation, reduces manual intervention, reduces labor intensity, and improves production efficiency; at the same time, a dust removal and filtering device 20 is provided to absorb and filter the smoke generated during welding of the workpiece, thereby reducing environmental pollution and manual exposure, and protecting the health of operators.

[0028] For ease of description and understanding, the X-axis direction of the two-dimensional coordinate system in the illustrated structure is defined as the first direction, and the Y-axis direction is defined as the second direction. It should be noted that the workpiece in this embodiment is a cylinder seat.

[0029] In this embodiment, the clamping assembly 11 further includes a first driving member (not shown), which can drive the first clamping member 112 and the second clamping member 115 to move closer to or farther from each other along a first direction, so as to drive the first clamping member 112 and the second clamping member 115 to move closer to each other to clamp the workpiece or move farther from each other to release the workpiece. The first clamping member 112 and the second clamping member 115 move closer to each other to clamp the workpiece between them, and the workpiece can be quickly clamped and positioned. Compared with the method of repeatedly measuring with a tape measure by an operator, the positioning accuracy is high, and it takes less time, saving time and effort.

[0030] In this embodiment, the clamping assembly 11 further includes a first connecting member 113, a first screw rod 114, a second connecting member 116 and a second screw rod 117. The first clamping member 112 is fixedly connected to the first connecting member 113, the first connecting member 113 and the first screw rod 114 are connected by threaded fitting, the second clamping member 115 is fixedly connected to the second connecting member 116, and the second connecting member 116 and the second screw rod 117 are connected by threaded fitting. The clamping assembly 11 further includes a coupling 118, the first screw rod 114 and the second screw rod 117 are relatively fixedly connected by the coupling 118, the output shaft of the first driving member is connected to the first screw rod 114 to drive the first screw rod 114 to rotate around its own axis direction and the second screw rod 117 to rotate around its own axis direction, and at the same time, the first connecting member 113 and the second connecting member 116 move toward or away from each other along the first direction, driving the first clamping member 112 and the second clamping member 115 to approach each other in the first direction to clamp the workpiece or move away from each other to release the workpiece. Specifically, the first clamping member 112 and the second clamping member 115 may both be plate-shaped.

[0031] Specifically, a first rotating through hole is provided on the surface of the first connecting member 113, and a second rotating through hole is provided on the surface of the second connecting member 116. The first screw rod 114 and the second screw rod 117 have the same diameter. The first screw rod 114 is rotationally connected to the first connecting member 113 through the first rotating through hole, and the second screw rod 117 is rotationally connected to the second connecting member 116 through the second rotating through hole. One end of the coupling 118 is fixedly connected to the first screw rod 114, and the other end is fixedly connected to the second screw rod 117. The first driving member is a motor, and the motor drives the first screw rod 114 to rotate. While the first screw rod 114 rotates, the second screw rod 117 fixedly connected to the first screw rod 114 through the coupling 118 rotates synchronously, and the first connecting member 113 threadedly connected to the first screw rod 114 moves in the first direction, and the second connecting member 116 threadedly connected to the second screw rod 117 moves in the first direction. Of course, the first driving member can also drive the second screw rod 117 to rotate. It should be noted that the first screw rod 114 and the second screw rod 117 are relatively fixedly connected by a coupling 118, and the first driving member drives the first screw rod 114 and the second screw rod 117 to rotate together. The external thread of the first screw rod 114 and the external thread of the second screw rod 117 have opposite patterns, so that during the rotation of the first screw rod 114 and the second screw rod 117, the movement directions of the first connecting member 113 and the second connecting member 116 respectively connected thereto are opposite, so that the movement between the first connecting member 113 and the second connecting member 116 is toward or away from each other. Therefore, the first connecting member 113 and the second connecting member 116 realize the movement in the first direction by respectively connecting with the threads of the first screw rod 114 and the second screw rod 117, and synchronously drive the first clamping member 112 and the second clamping member 115 to move toward or away from each other.

[0032] It can be understood that the first screw rod 114 and the second screw rod 117 can be relatively independent, and the coupling 118 is not used to relatively fix the two. In this way, two first driving members are required to drive the first screw rod 114 and the second screw rod 117 to rotate respectively. The two first driving members work simultaneously to drive the first screw rod 114 to rotate around its own axis direction and the second screw rod 117 to rotate around its own axis direction, so that the first connecting member 113 and the second connecting member 116 are close to or away from each other, and synchronously drive the first clamping member 112 and the second clamping member 115 to move toward or away from each other. When the texture of the external threads on the first screw rod 114 and the second screw rod 117 are in the same direction, the direction in which the first screw rod 114 is driven to rotate by the first driving member and the direction in which the second screw rod 117 is driven to rotate by the first driving member are opposite; when the texture of the external threads on the first screw rod 114 and the second screw rod 117 are opposite, the direction in which the first screw rod 114 is driven to rotate by the first driving member and the direction in which the second screw rod 117 is driven to rotate by the first driving member are the same.

[0033] The workpiece is clamped and positioned mainly by the first clamping member 112 and the second clamping member 115 moving toward each other. It is understood that other structures such as a guide rail structure can also be used to achieve the movement of the first clamping member 112 and the second clamping member 115 in the first direction. For example, when the guide rail structure is used, the first clamping member 112 is slidably arranged on the first guide rail along the first direction, and the second clamping member 115 is slidably arranged on the second guide rail along the first direction, and then the movement of the first clamping member 112 and the second clamping member 115 is driven by an oil cylinder or a pneumatic cylinder.

[0034] In this embodiment, the first clamping member 112 is provided with a first heat dissipation hole 1121, and the second clamping member 115 is provided with a second heat dissipation hole 1151. There are a plurality of first heat dissipation holes 1121 and they are spaced apart along the second direction, and there are a plurality of second heat dissipation holes 1151 and they are spaced apart along the second direction. The first clamping member 112 is also provided with a plurality of first ventilation holes 1122 and they are spaced apart along the second direction; the second clamping member 115 is also provided with a plurality of second ventilation holes 1152 and they are spaced apart along the second direction. A plurality of first heat dissipation holes 1121 and first ventilation holes 1122 are provided on the surface of the first clamping member 112, and a plurality of second heat dissipation holes 1151 and second ventilation holes 1152 are provided on the surface of the second clamping member 115. When the workpiece is welded and riveted, heat is generated on the surface of the workpiece, and the heat on the surface of the workpiece can be dissipated through the first heat dissipation holes 1121, the second heat dissipation holes 1151, the first ventilation holes 1122 and the second ventilation holes 1152, so as to avoid burns to the operator due to excessive temperature of the workpiece surface after riveting.

[0035] In this embodiment, the clamping assembly 12 includes a second driving member (not shown), a clamping member 122, a third connecting member 123 and a third screw rod 124. The clamping member 122 is fixedly connected to the third connecting member 123. The third connecting member 123 and the third screw rod 124 are connected by threaded fitting. The output shaft of the second driving member is connected to the third screw rod 124 to drive the third screw rod 124 to rotate around its own axis. Specifically, the clamping member 122 can be plate-shaped.

[0036] In this embodiment, the first clamping member 112 and the second clamping member 115 are respectively located on both sides of the pressing member 122, and the pressing member 122 is located at one end of the first clamping member 112 and the second clamping member 115, so that the clamping assembly 11 and the pressing assembly 12 can surround the workpiece in terms of position distribution, that is, the workpiece is placed between the clamping assembly 11 and the pressing assembly 12. When the operator needs to weld and rivet the workpiece, the first driving member rotates and pushes the first clamping member 112 and the second clamping member 115 to approach each other in the first direction to clamp and position the workpiece, and then the second driving member rotates and pushes the pressing member 122 to move along the second direction to vault the wall of the workpiece. The first clamping member 112, the second clamping member 115 and the pressing member 122 simultaneously approach the workpiece to clamp and position the workpiece, so that the riveting tool can adapt to different types of workpieces and improve the scope of use of the tool.

[0037] In this embodiment, Figure 4-5 As shown, the dust removal and filtering device 20 includes a filter component 21 and an exhaust component 22. The filter component 21 includes a filter box 211, a filter unit 212 and an atomizing unit 213. The filter box 211 is fixedly connected to the first clamping member 112 or the second clamping member 115. The filter box 211 has an open first side and a second side, and the second side faces the space between the first clamping member 112 and the second clamping member 115. The filter box 211 has a receiving cavity. The exhaust component 22 is arranged on the first side of the filter box 211 and is fixedly connected to the filter box 211, and is used to absorb smoke and dust and make it enter the receiving cavity. The filter unit 212 is arranged in the receiving cavity of the filter box 211, and is used to filter the airflow with smoke and dust. The atomizing unit 213 can be atomized in the receiving cavity to generate water vapor, and the water vapor generated by atomization absorbs the smoke and dust located in the receiving cavity. The second side is provided with an exhaust hole 251, and the filter unit 212 is located between the first side and the second side.

[0038] Specifically, there are two dust removal and filtering devices 20, and they are detachably connected to the first clamp 112 and the second clamp 115, respectively. The two dust removal and filtering devices 20 are respectively located on the opposite sides of the first clamp 112 and the second clamp 115, that is, one filter box 211 is located on the side of the first clamp 112 away from the second clamp 115 and is detachably connected to the first clamp 112, and the other filter box 211 is located on the side of the second clamp 115 away from the first clamp 112 and is detachably connected to the second clamp 115. A workpiece will be placed between the first clamp 112 and the second clamp 115, so that the arrangement avoids occupying the space for placing the workpiece, and the placement of the workpiece interferes with the dust removal and filtering device 20. The interior of the filter box 211 is a rectangular cavity (accommodation cavity), and the filter unit 212 is plugged into the filter box 211 and extends into the accommodation cavity, and is detachably connected to the filter box 211. The filter box 211 has an open first side and a second side. The exhaust assembly 22 is placed on the first side of the filter box 211 and fixedly connected to the filter box 211. The second side of the filter box 211 faces the space between the first clamp 112 and the second clamp 115, and the second side is provided with an exhaust hole 251, so that the gas and the smoke impurities generated by welding enter the filter box 211 together with the gas. The second side is arranged opposite to the first side, which can make it easier for the exhaust assembly 22 to suck the gas into the filter box 211. The filter unit 212 is located between the first side and the second side. The filter unit 212 is plugged into the top of the filter box 211. The filter assembly 21 also includes a handle 214, which is exposed at the top of the filter box 211 and fixedly connected to the filter unit 212. The collection box 23 can be placed in the accommodating cavity from the second side. The interior of the collection box 23 is a rectangular cavity for collecting water droplets adsorbed with smoke. The collection box 23 is arranged corresponding to the atomization unit. Specifically, the collection box 23 is located below the atomization unit. One end of the drain valve 24 passes through the side wall of the filter box 211 and the side wall of the collection box 23 and is threadedly connected to the collection box 23, so as to discharge the liquid in the collection box 23. At the same time, the dust removal and filtering device 20 also includes a sealing plate 25, which is located on the second side of the filter box 211 and is fixedly connected to the filter box 211, and the air suction hole 251 is opened on the sealing plate 25. After the exhaust assembly 22 starts working, the gas enters the filter box 211 from the air suction hole 251. The exhaust assembly 22 is provided with a fan, which can suck gas when the fan rotates.

[0039] During operation, when the operator is performing welding and riveting, a large amount of smoke and dust will be generated. By energizing the fan, the fan starts to rotate, and the rotating fan pumps the air in the cavity of the filter box 211. The smoke and dust generated by welding and riveting flows into the cavity of the filter box 211 through the air extraction holes 251 on the sealing plate 25. At the same time, the air in the filter box 211 will also be discharged to the outside of the filter box 211 through the exhaust assembly 22. By inserting the filter unit 212 in the cavity of the filter box 211, the air discharged to the outside of the filter box 211 through the exhaust assembly 22 will first pass through the filter unit 212 before being discharged. The filter unit 212 filters the airflow, reduces environmental pollution and artificial exposure, and protects the health of workers. The top surface of the filter box 211 is connected with an atomization unit 213 (atomization nozzle). One end of the atomizing unit 213 is connected to a water pipe, and the input end of the water pipe is connected to a water pump. By energizing the water pump, the water pump pressurizes water and sends it to the cavity of the atomizing unit 213, and the pressurized liquid is sprayed out and atomized through the output end of the atomizing unit 213. The water droplets generated by atomization adsorb the smoke generated by welding riveting and drop it into the collection box 23, thereby reducing the particulate matter in the smoke. By setting a drain valve 24, the drain valve 24 is interconnected with the cavity of the collection box 23, and the valve of the drain valve 24 is opened, and the liquid in the cavity of the collection box 23 is discharged through the drain valve 24, thereby preventing the liquid from accumulating in the cavity of the collection box 23 and affecting the normal operation of the dust removal filter device 20. By fixing two handles 214 on the top surface of the filter unit 212, when the filter unit 212 reaches its service life, the operator can pull out the filter unit 212 through the handle 214, which is convenient for placing the unused filter unit 212 into the cavity of the filter box 211, thereby simplifying the operator's workflow.

[0040] In this embodiment, the riveting tool further includes an operating table 30, and the clamping device 10 is installed on the operating table 30, and the operating table 30 is used to place the workpiece. The operating table 30 is provided with a first sliding groove adapted to the first connecting member 113 and a second sliding groove adapted to the second connecting member 116. One end of the first connecting member 113 passes through the first sliding groove and is slidably connected to the operating table 30, and one end of the second connecting member 116 passes through the second sliding groove and is slidably connected to the operating table 30.

[0041] The steps for using the riveting tool of the utility model are as follows: First, place the workpiece on the operating table 30, and the workpiece is located in the space enclosed by the first clamping member 112, the second clamping member 115 and the pressing member 122. Under the action of the first driving member, the first clamping member 112 and the second clamping member 115 approach each other and move to abut against the workpiece. At this time, the first clamping member 112 and the second clamping member 115 limit the freedom of the workpiece in the first direction and clamp the workpiece in place. Subsequently, the pressing member 122 moves toward the second direction close to the workpiece under the action of the second driving member and moves to abut against the workpiece. The first clamping member 112, the second clamping member 115 and the pressing member 122 realize the clamping and positioning of the workpiece.
