Technical Field

[0001] This utility model relates to the field of riveting machine technology, and in particular to a handheld riveting machine with pressure displacement monitoring, a control cabinet and a riveting system. Background Technology

[0002] Currently, most common riveting machines are fixed-type. These machines are expensive due to their fixed location and lack of flexibility for manual handheld operation, placing a cost burden on businesses. Others are powered by pneumatic control, but these are inflexible in operation and lack pressure and displacement monitoring capabilities. This results in imprecise pressure and displacement control during operation, failing to meet the need for data traceability. Therefore, it is necessary to provide a handheld riveting machine, control cabinet, and riveting system with pressure and displacement monitoring to overcome these shortcomings. Utility Model Content

[0003] The purpose of this utility model is to provide a handheld riveting machine, control cabinet and riveting system with pressure displacement monitoring, which aims to solve the problem that the pressure and displacement cannot be accurately controlled during the operation of existing handheld riveting machines, so as to facilitate the flexible operation of manual handheld riveting, and can also have the function of monitoring pressure and displacement at a low cost, so that the pressure and displacement can be accurately controlled during the operation and the operation data can be traced.

[0004] To achieve the above objectives, this utility model provides a handheld riveting machine with pressure displacement monitoring, comprising:

[0005] C-type clamp body;

[0009] A displacement sensor, comprising a sensor body and a pull rod capable of relative displacement with respect to the sensor body; the pull rod is fixedly connected to the synchronous displacement plate;

[0010] The riveting die is fixed to the C-shaped clamp body and is coaxially spaced from the piston rod.

[0011] In a preferred embodiment, the C-type clamp body includes a connecting block and a first fixing block and a second fixing block respectively disposed at both ends of the connecting block; the gas-liquid booster cylinder body is fixed on the first fixing block, and the riveting die is fixed on the second fixing block.

[0012] In a preferred embodiment, a sensor fixing plate is provided on the side of the first fixing block, and the sensor body is fixed to the sensor fixing plate.

[0013] In a preferred embodiment, the system further includes a guide anti-rotation component; the guide anti-rotation component includes a linear bearing and a guide anti-rotation rod; the sensor body and the linear bearing are respectively fixed to the left and right sides of the first fixing block; the guide anti-rotation rod passes through the inner side of the linear bearing and is fixedly connected to the synchronous displacement plate.

[0014] In a preferred embodiment, the guide anti-rotation assembly further includes a protective cover disposed on the side of the first fixing block near the guide anti-rotation rod, the protective cover being used to cover the portion of the guide anti-rotation rod extending out of the linear bearing in a direction away from the second fixing block.

[0015] In a preferred embodiment, the synchronous displacement plate has a central through hole and a first through hole and a second through hole respectively spaced apart on the left and right sides of the central through hole; the piston rod is vertically inserted and fixed in the central through hole, the pull rod is vertically inserted and fixed in the first through hole, and the guide anti-rotation rod is vertically inserted and fixed in the second through hole.

It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0028] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0029] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0030] In an embodiment of this utility model, a handheld riveting machine 100 with pressure displacement monitoring is provided for riveting workpieces by hand.

[0031] like Figures 1-2 The handheld riveting machine 100 with pressure displacement monitoring includes: a C-type clamp body 10, a pneumatic-hydraulic booster cylinder 20, a synchronous displacement plate 30, a pressure sensor 40, a displacement sensor 50, and a riveting die 60.

[0032] The C-type clamp body 10 includes a connecting block 11 and a first fixing block 12 and a second fixing block 13 respectively located at both ends of the connecting block 11. The first fixing block 12 and the second fixing block 13 are located at both ends of the connecting block 11 and extend along the same side, thus being spaced vertically to form a working space that facilitates riveting operations. Furthermore, an operating handle 14 can be provided on the back of the connecting block 11 relative to the working space, making it convenient for the operator to hold.

[0033] The pneumatic-hydraulic booster cylinder 20 includes a cylinder body 21 and a piston rod 22. The pneumatic-hydraulic booster cylinder 20 can be a common direct-pressure pneumatic-hydraulic booster cylinder (directly using air pressure to drive hydraulic oil to generate high pressure), a pre-pressure pneumatic-hydraulic booster cylinder (pre-pressurizing the hydraulic oil before boosting), etc., all including an air port and a hydraulic port. It should be noted that the principle of the pneumatic-hydraulic booster cylinder body 21 driving the piston rod 22 to extend and retract axially can be found in existing technology, and will not be elaborated further here. Specifically, the pneumatic-hydraulic booster cylinder body 21 is fixed to one end of the C-shaped clamp 10, particularly at the end of the first fixing block 12 away from the second fixing block 13.

[0034] The synchronous displacement plate 30 is fixed to the piston rod 22. For example, the synchronous displacement plate 30 can be a plate-shaped piston rod clamping block, which is clamped to the piston rod 22 by means of two clamping blocks with semi-circular grooves and screw nuts, so that the piston rod 22 can drive the synchronous displacement plate 30 to move synchronously axially.

[0035] The pressure sensor 40 is coaxially coupled to the end of the piston rod 22 furthest from the body 21 of the pneumatic-hydraulic booster cylinder. That is, when the piston rod 22 applies pressure to the workpiece to be riveted, the pressure is first transmitted to the pressure sensor 40, and then transmitted to the workpiece through the pressure sensor 40. Therefore, the pressure can be detected by the pressure sensor 40 in real time. It should be noted that the specific structure and implementation principle of the pressure sensor 40 can be found in existing technology, and will not be elaborated upon here.

[0036] The displacement sensor 50 includes a sensor body 51 and a pull rod 52 that can be displaced relative to the sensor body 51. Specifically, a sensor fixing plate 53 is provided on the side of the first fixing block 12, and the sensor body 51 is fixed to the sensor fixing plate 53. The pull rod 52 is fixedly connected to the synchronous displacement plate 30, so that when the synchronous displacement plate 30 extends and retracts with the piston rod 22, the pull rod 52 also extends and retracts synchronously with the synchronous displacement plate 30. Therefore, the displacement of the pull rod 52 is the same as the displacement of the piston rod 22. For example, the sensor body 51 has a precision resistor track (such as conductive plastic or wire-wound resistor) inside. The movement of the pull rod 52 will change the effective length of the resistor, causing the resistance value to change linearly. Therefore, the displacement of the pull rod 52 can be determined by detecting the change in resistance value, and thus the displacement of the piston rod 22 can be determined. This calculation method is a conventional technique in the field of electrical engineering and will not be elaborated further here.

[0037] The riveting die 60 is fixed to the C-shaped clamp body 10 and is coaxially spaced from the piston rod 22. Specifically, the riveting die 60 is fixed to the side of the second fixing block 13 closest to the first fixing block 12. The second fixing block 13 has a mounting hole 601, on which the riveting die 60 is detachably mounted. Therefore, the corresponding riveting die 60 mounted on the mounting hole 601 can be replaced according to the different types of workpieces to be riveted. During the riveting operation, the piston rod 22 and the riveting die 60 are located on opposite sides of the workpiece to be riveted. The riveting die 60 mainly serves to support and limit the movement of the workpiece.

[0038] Furthermore, the handheld riveting machine 100 with pressure displacement monitoring also includes a guide anti-rotation assembly 70. The guide anti-rotation assembly 70 includes a linear bearing 71 and a guide anti-rotation rod 72. The sensor body 51 and the linear bearing 71 are respectively fixed to the left and right sides of the first fixed block 12, thereby balancing the forces on both sides of the synchronous displacement plate 30. The guide anti-rotation rod 72 passes through the inner side of the linear bearing 71 and can move up and down along the linear bearing 71. The guide anti-rotation rod 72 is fixedly connected to the synchronous displacement plate 30, meaning that the guide anti-rotation rod 72 can move synchronously with the synchronous displacement plate 30 and guide the movement of the synchronous displacement plate 30, while preventing the synchronous displacement plate 30 from rotating horizontally.

[0039] Furthermore, the guide anti-rotation assembly 70 also includes a protective cover 73 disposed on the side of the first fixing block 12 near the guide anti-rotation rod 72. The protective cover 73 is used to cover the portion of the guide anti-rotation rod 72 that extends out of the linear bearing 71 in a direction away from the second fixing block 13, thereby preventing the extension and retraction of the guide anti-rotation rod 72 from causing damage to the human hand holding the operating handle 14.

[0040] Furthermore, the synchronous displacement plate 30 has a central through hole 301 and a first through hole 302 and a second through hole 303 respectively spaced on the left and right sides of the central through hole 301. The piston rod 22 is vertically inserted and fixed in the central through hole 301 (or it can be formed by two semi-circular grooves), the pull rod 52 is vertically inserted and fixed in the first through hole 302, and the guide anti-rotation rod 72 is vertically inserted and fixed in the second through hole 303.

[0041] like Figure 1 and Figure 3 As shown, this utility model also provides a control cabinet 200 for use with the handheld riveting machine 100 with pressure displacement monitoring as described in any of the above embodiments. That is, the power drive for the riveting action adopts a split-type air-liquid pressurization structure. This structure makes the overall weight of the riveting pliers lighter and facilitates flexible manual handheld operation.

[0042] Specifically, the control cabinet 200 includes a cabinet body 201 and a booster 202 disposed within the cabinet body 201. The booster 202 is used for separate-type gas-liquid boosting of the gas-liquid booster cylinder 20. The booster 202 includes an air port and a hydraulic port. The air port of the booster 202 is connected to the air port of the gas-liquid booster cylinder 20 via a first conduit 203, and the hydraulic port of the booster 202 is connected to the hydraulic port of the gas-liquid booster cylinder 20 via a second conduit 204.

[0043] This utility model also provides a riveting system 300 based on a split-type gas-liquid pressurization, such as... Figure 1 As shown, it includes a handheld riveting machine 100 with pressure displacement monitoring as described in any of the above embodiments and a control cabinet 200 as described in the above embodiments.

[0044] In summary, the handheld riveting machine 100 with pressure displacement monitoring, control cabinet 200, and riveting system 300 provided by this utility model utilize a synchronous displacement plate 30 fixed to the piston rod 22 of the pneumatic-hydraulic booster cylinder 20. When the piston rod 22 moves, it synchronously drives the pull rod 52 of the displacement sensor 50 to move. Therefore, the displacement of the piston rod 22 can be determined by measuring the displacement of the pull rod 52 through the sensor body 51. Simultaneously, a pressure sensor 40 is coaxially mounted on the piston rod 22. When the workpiece to be riveted is placed between the pressure sensor 40 and the riveting die 60, the pressure sensor 40 can measure the pressure applied to the workpiece by the piston rod 22. This facilitates flexible manual handheld riveting operation and provides pressure and displacement monitoring functions at a low cost, enabling precise control of pressure and displacement during operation and traceability of work data.

[0045] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
