Detailed Implementation

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims. Example 1

[0026] like Figures 1 to 4 As shown, the present invention provides a mobile stepping clamping device 100 for windshield system profiles, including a handheld module 10, a pressure application module 20 mounted on the handheld module 10, an execution module 30 mounted on the pressure application module 20, and a distance fixing module 40. The distance fixing module 40 selects the clamping position on the profile, and the handheld module 10 provides power to the pressure application module 20. The pressure application module 20 converts the direction of the power application, driving the execution module 30 to perform the clamping action, thereby completing the distance-fixed clamping of the profile, achieving a uniform clamping force on the profile.

[0027] like Figure 2 As shown, the handheld module 10 includes a control unit 110. One end of the control unit 110 is connected to an air source, and the other end is connected to a pressure application module 20. The air source provides air pressure to the control unit 110, and a pneumatic motor 112 is installed inside the control unit 110. The pneumatic motor 112 converts the air pressure into torque, which the control unit 110 then transmits to the pressure application module 20. An air source switch 111 is installed on the control unit 110, which controls the opening and closing of the air circuit within the control unit 110, thereby controlling the start and stop of the pneumatic motor 112. The position of the pressure application module 20 can be moved using the control unit 110, aligning it with the desired clamping position on the profile. The operator uses the handheld module 10 to control the start, stop, and movement of the clamp, and can change the clamping position on the profile.

[0028] The pressure applying module 20 comprises a pressure applying shell 240, a crankshaft 210 arranged in the pressure applying shell 240, a gear set 220 sleeved on the crankshaft 210, and a piston 230 arranged below the crankshaft 210. The crankshaft 210 rotates to drive the piston 230 to move reciprocally, and the piston 230 transmits the torque to the executing module 30 when moving.

[0029] The crankshaft 210 is rotatably arranged in the pressure applying shell 240, and an eccentric section 211 is arranged on the crankshaft 210, which is eccentric to the rotation center of the end of the crankshaft 210. The gear set 220 is arranged between the end of the crankshaft 210 and the control member 110. Specifically, a driving wheel of the gear set 220 is fixed on the control member 110, and a driven wheel of the gear set 220 is finally arranged on the end of the crankshaft 210. The torque output by the control member 110 is transmitted to the gear set 220 through the driving wheel, and is transmitted to the crankshaft 210 through the driven wheel after being gradually reduced by the gear set 220. The piston 230 is arranged corresponding to the eccentric section 211 of the crankshaft 210, and is fixedly connected to the eccentric section 211 of the crankshaft 210. The cylinder of the piston 230 is fixed on the pressure applying shell 240. When the crankshaft 210 rotates, the eccentric section 211 drives the piston 230 to move reciprocally in the cylinder.

[0030] The executing module 30 comprises an executing shell 310 fixedly arranged below the pressure applying shell 240, a fixed pressing block 320 arranged in the executing shell 310, and a movable pressing block 330 arranged above the fixed pressing block 320.

[0031] The executing shell 310 is fixed on the end of the pressure applying shell 240, and the fixed pressing block 320 is fixedly arranged in the executing shell 310. A buffer is arranged between the fixed pressing block 320 and the executing shell 310. When the fixed pressing block 320 is extruded, the buffer can slow down the pressure on the executing shell 310. The movable pressing block 330 is fixed on the lower end of the piston 230, and can move up and down relative to the fixed pressing block 320 under the driving of the piston 230. A profiled material is arranged between the fixed pressing block 320 and the movable pressing block 330. Under the driving of the crankshaft 210, the piston 230 drives the movable pressing block 330 to move towards the fixed pressing block 320. When the movable pressing block 330 moves, it can clamp the profiled material and the shed cloth, so that the profiled material can clamp the edge of the shed cloth.

[0032] As shown in Figure 1 , Figure 3 , Figure 4 , the distance setting module 40 comprises a clamping frame 410 arranged outside the executing module 30, a pressure applying member 420 arranged on the clamping frame 410, and a clamping wheel 430.

[0033] The clamping frame 410 comprises a fixed frame 411 surrounding the fixed pressing block 320, a movable frame 412 parallel to the fixed frame 411 and surrounding the movable pressing block 330, and a limiting piece 413 arranged between the fixed frame 411 and the movable frame 412. The fixed frame 411 and the movable frame 412 are both substantially in a U-shaped structure, the openings of the fixed frame 411 and the movable frame 412 are both arranged away from the pressing module 20, the fixed frame 411 is fixedly installed on the outer side of the execution shell 310, the movable frame 412 surrounds the outer side of the execution shell 410, and the movable frame 412 is connected to the upper side of the fixed frame 411 in parallel and adjustably through the limiting piece 413. A pull handle 416 is installed on the outer side wall of the movable frame 412, the movable frame 412 can be moved relative to the fixed frame 411 through the pull handle 416, and the distance between the movable frame 412 and the fixed frame 411 can be changed. The fixed frame 411 is provided with a positioning sharp 414 on both sides of the opening, the positioning sharp 414 is made of high-hardness material, and the positioning sharp 414 is used for hitting positioning on the profile. Specifically, the fixed frame 411 is provided with a support rod 415 on both sides of the opening, the positioning sharp 414 is inserted into the end of the support rod 415, the hitting center of the positioning sharp 414 is located between the fixed frame 411 and the movable frame 412, and the positioning sharp 414 can hit and mark the surface of the profile when moving on the support rod 415. One end of the limiting piece 413 is installed on the fixed frame 411, the other end of the limiting piece 413 is movably inserted into the movable frame 412, the movable frame 412 is always kept parallel to the fixed frame 411 during movement, the limiting piece 413 is preferably a plurality of parallel pin shafts with shaft shoulders in the embodiment, the end with a larger diameter of the pin shaft is detachably installed on the fixed frame 411, the movable frame 412 is slidably inserted into the end with a smaller diameter of the pin shaft, and the sliding distance of the movable frame 412 on the limiting piece 413 is limited by the shaft shoulder. After the limiting length of the limiting piece 413 is adjusted, the minimum distance between the movable frame 412 and the fixed frame 411 can also be limited. The pressing piece 420 and the limiting piece 413 are arranged at both ends of the fixed frame 411, the pressing piece 420 has elastic performance, the pressing piece 420 is detachably connected to the fixed frame 411 and the movable frame 412, the movable frame 412 has a tendency to move towards the fixed frame 411 by means of the elasticity of the pressing piece 420, that is, the movable frame 412 and the fixed frame 411 have a clamping force. The clamping wheels 430 are installed at the ends of the fixed frame 411 and the movable frame 412, the clamping wheels 430 are divided into two groups, each group has two clamping wheels 430, each group of two clamping wheels 430 is arranged on the two sides of the profile corresponding to the movable frame 412 and the fixed frame 411, the clamping wheels 430 can press the profile under the extrusion of the fixed frame 411 and the movable frame 412, and the profile is slid along the length direction of the profile by means of the sliding of the clamping wheels 430 and the clamping force.

[0034] In this embodiment, before using the movable step clamping device 100 for the windshield system profile, the positions of the fixed pressure block 320 and the movable pressure block 330 are adjusted by the control component 110 so that the fixed pressure block 320 and the movable pressure block 330 are located on the upper and lower sides of the profile respectively. Then, by pulling the handle 416, the movable frame 412 is moved away from the fixed frame 411, and the distance between the two clamping wheels 430 in each group is controlled so that the clamping wheels 430 are clamped on the upper and lower sides of the profile under the traction of the pressure component 420. After the clamping wheels 430 are in contact with the profile surface, the pins with different shoulder positions are replaced to control the distance between the movable frame 412 and the fixed frame 411. With the elastic traction of the pressure component 420, the clamping force of the clamping wheels 430 on the profile can be controlled. The clamping rollers 430 can roll along the profile. Since the profile needs to maintain its strength while also being able to change its opening size, most of the profile's sidewalls are pointed structures. Once the clamping rollers 430 are in place, they are difficult to detach from the profile surface naturally. The clamping rollers 430 on both sides of the profile can form a clamp, so that the clamping device 100 can only move along the length of the profile. When the clamping device 100 moves to the pressing position, it selects the positioning tip 414 away from the starting position along the moving direction and leaves a mark on the profile by tapping or other means, while simultaneously pressing the profile. The clamping device 100 is moved a fixed distance and continues to move to the next clamping position. After clamping, the mark is tapped. The above process is repeated until another positioning tip 414 and the mark coincide. The clamping continues at a fixed distance along the mark until the profile clamps the fabric.

[0035] In the above process, after the pressure module 20 and the execution module 30 are moved into place by the handheld module 10, the pneumatic motor 112 is started. The pneumatic motor 112 transmits torque to the crankshaft 210 through the gear set 220. Under the push of the eccentric section 211, the piston 230 drives the movable pressure block 330 to move towards the fixed pressure block 320 until the profile is squeezed and clamped on the edge of the tarpaulin, thus completing the clamping operation. Example 2

[0036] like Figure 5 As shown, in this embodiment, the limiting member 413 includes two screws fixedly installed on the fixed frame 411. Each screw has a limiting nut inserted into it. The movable frame 412 is movably inserted into the screw and rests on the limiting nut. The positions of the two limiting nuts on the screws are adjusted to be parallel. Under the constraint of the limiting nuts and screws, the movement direction of the movable frame 412 relative to the fixed frame 411 is restricted. The pressure applying member 420 is a tension spring with both ends attached. That is, when the pressure applying member 420 is blocked by the limiting nut, the movable frame 412 is restricted by the pressure applying member 420 to fix the distance between the screw and the fixed frame 411. In application, the position of the limiting nut on the screw should first be adjusted according to the thickness of the profile until the clamping wheel 430 clamps the profile. Example 3

[0037] As Figure 6 and Figure 7 shown, in the present embodiment, the limiting member 413 is preferably a scissors type hinge mechanism, specifically, the limiting member 413 comprises a limiting rod 4131, a hinge rod 4132 inserted in the middle position of the limiting rod 4131, and a limiting block 4133 slidably mounted on the fixed frame 411 and the movable frame 412. The limiting rod 4131 is provided with two groups on both sides of the opening of the fixed frame 411, each group has two, and the two limiting rods 4131 of each group are cross placed, the hinge rod 4132 is inserted and mounted on the cross position of the limiting rod 4131, the end of the limiting rod 4131 is hinged to the limiting block 4133, and the limiting block 4133 is slidably clamped on the fixed frame 411 and the movable frame 412. The movement direction of the movable frame 412 is limited by the limiting rod 4131, which ensures that the movable frame 412 can move parallel to the fixed frame 411, so that the wheel clamping device 430 can stably clamp the two sides of the profile, and the selection of the clamping position on the profile by the clamping gun is facilitated.

[0038] Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined according to the scope of the claims.
