[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0027] As Figures 1-5 shown, a continuous body panel cutting device includes a gantry 1;

[0028] A cutting knife 2 assembled on the gantry 1;

[0029] A bracket 3 inclinedly arranged on the gantry 1, on which a flexion and extension arm 4 for restricting the panel is assembled, including a fixed seat 41 and a proximal phalanx 42 rotatably connected to the fixed seat 41;

[0030] A tendon rope 44 for pulling the proximal phalanx 42 close to the panel.

[0031] Specifically, a guide shell 36 for the tendon rope 44 to pass through is arranged on the edge of the bracket 3 to avoid interference of the tendon rope 44 with the cutting of the panel, and a claw 5 is assembled on the bracket 3.

[0032] Further, the panel is hoisted onto the bracket 3, and then the tendon rope 44 is manually pulled, or the tendon rope 44 is wound around a winding machine, and the winding machine is started so that the tendon rope 44 is straightened and pulls the proximal phalanx 42 close to the panel. At this time, the proximal phalanx 42 rotates around the connection with the fixed seat 41 until it stops when it is close to the surface of the panel, and the panel is grasped and restricted by the pulling force of the tendon rope 44, and then the cutting knife 2 is started for cutting.

[0033] In the above technology, through the design of the flexion and extension arm 4 and the tendon rope 44, the proximal phalanx 42 stops rotating until it is close to the surface of the panel, and the panel is grasped and restricted by the pulling force of the tendon rope 44, which can be adaptively adjusted according to the structures of different panels without repeated debugging.

[0034] As a further embodiment provided by the present utility model, the flexing and extending arm 4 further includes a distal phalanx 43 rotatably connected to the proximal phalanx 42. In the initial state, a predetermined included angle is maintained between the distal phalanx 43 and the proximal phalanx 42.

[0035] Specifically, a return spring 46 is provided on the distal phalanx 43. The two ends of the return spring 46 are respectively connected to the upper side of the rotating joint of the proximal phalanx 42 and the distal phalanx 43. Due to the elasticity of the return spring 46, the included angle between the proximal phalanx 42 and the distal phalanx 43 is maintained at a predetermined degree. When the distal phalanx 43 rotates relative to the proximal phalanx 42 under the influence of an external force, the return spring 46 stretches and stores elastic energy. Subsequently, without the influence of an external force, the potential energy of the return spring 46 is released, and the included angle between the proximal phalanx 42 and the distal phalanx 43 is restored to the predetermined included angle.

[0036] As a further embodiment provided by the present utility model, it further includes a guiding block 45 provided on the flexing and extending arm 4 and used for guiding the tendon rope 44.

[0037] Specifically, the guiding block 45 is divided into a first guiding block provided on the center line of the fixed seat 41 and a second guiding block provided on the center line of the proximal phalanx 42. The first end of the tendon rope 44 is fixedly provided on the side surface of the distal phalanx 43 close to the bracket 3. The second end winds around the upper side of the second guiding block from the lower side of the rotating joint of the distal phalanx 43, and then winds around the upper side of the first guiding block along the lower side of the rotating joint of the proximal phalanx 42. As Figure 3 shown, then under manual traction or winding by a winding machine, first drive the distal phalanx 43 to approach the lower side of the proximal phalanx 42. After reaching the limit or being blocked by the covering member, then drive the proximal phalanx 42 to approach the lower side of the fixed seat 41, so that the combination of the proximal phalanx 42 and the distal phalanx 43 realizes the grasping restriction of the covering member.

[0038] As a further embodiment provided by the present utility model, an arc-shaped bottom plate 31 for accommodating the bottom of the covering member is provided on the lower side of the bracket 3, and an airbag 33 is provided at the bottom of the inner wall of the arc-shaped bottom plate 31.

[0039] Specifically, the covering member is hoisted onto the bracket 3, and the covering member slides down along the inclined surface of the bracket 3. The bottom of the covering member enters the inside of the arc-shaped bottom plate 31 and is protected and buffered by the airbag 33 to avoid damage to the covering member, and the contact part between the bracket 3 and the covering member is increased to realize multi-point limit.

[0040] As a further embodiment provided by the present utility model, a rotating plate 32 is rotatably provided on the arc-shaped bottom plate 31, and there is a pressing station in the rotation stroke of the rotating plate 32 where it presses against the arc-shaped bottom plate 31.

[0041] Specifically, with the axis of rotation of the rotating plate 32 as the boundary, the rotating plate 32 is divided into a long plate and a short plate. Under the action of its own weight, the covering member slides down along the inclined surface of the support 3. During the sliding process, it abuts against the long plate of the rotating plate 32 and pushes the rotating plate 32 to rotate, so that the short plate of the rotating plate 32 rotates to the pressing position to press against the side surface of the covering member, further restricting the covering member.

[0042] As yet another embodiment further provided by the present utility model, it further includes a plurality of bellows 35 for supporting the rotating plate 32. The two ends of the bellows 35 are respectively connected to the outer wall of the arc-shaped bottom plate 31 and the outer wall of the rotating plate 32, and the bellows 35 is under air pressure to switch between two states of expansion or contraction.

[0043] Specifically, the bellows 35 supports the rotating plate 32 in the contracted state, so that the long plate points to the axis of the arc-shaped bottom plate 31. Subsequently, the covering member slides down along the inclined surface of the support 3 under the action of its own weight. During the sliding process, it abuts against the long plate of the rotating plate 32 and pushes the rotating plate 32 to rotate, so that the short plate of the rotating plate 32 rotates to the pressing position to press against the side surface of the covering member. At this time, gas or liquid can be input into the bellows 35 through an air pump or a hydraulic pump, so that the bellows 35 expands, increasing the pressure on the short plate of the rotating plate 32, thereby making the pushing force of the short plate of the rotating plate 32 on the covering member greater.

[0044] As yet another embodiment further provided by the present utility model, the airbag 33 is used to supply air to the bellows 35.

[0045] Specifically, the covering member is hoisted onto the support 3 and slides down along the inclined surface of the support 3. The covering member squeezes the airbag 33 under the action of its own weight, so that the gas in the airbag 33 enters the bellows 35, and the bellows 35 expands, increasing the pressure on the short plate of the rotating plate 32, thereby making the pushing force of the short plate of the rotating plate 32 on the covering member greater.

[0046] As yet another embodiment further provided by the present utility model, a positioning plate 34 for clamping the covering member is provided on the upper surface of the airbag 33, and it is used to pull the tendon cord 44.

[0047] Specifically, the covering member slides down along the inclined surface of the support 3 under the action of its own weight, thereby driving the positioning plate 34 to slide downward. The positioning plate 34 pulls the tendon cord 44, first driving the distal phalanx 43 to approach the lower side of the proximal phalanx 42. After reaching the limit or being blocked by the covering member, it then drives the proximal phalanx 42 to approach the lower side of the fixed seat 41, so that the combination of the proximal phalanx 42 and the distal phalanx 43 realizes the grasping restriction of the covering member.

[0048] Working principle: Lift the covering part and hoist it onto the bracket 3. At this time, a predetermined clamping angle is maintained between the proximal knuckle 42 and the distal knuckle 43, which will not affect the covering part. Slide the covering part down along the inclined surface of the bracket 3. During the sliding process, it abuts against the long plate of the rotating plate 32 and pushes the rotating plate 32 to rotate, so that the short plate of the rotating plate 32 rotates to the pressing station to press against the side surface of the covering part, driving the positioning plate 34 to slide downward. The positioning plate 34 pulls the tendon rope 44, first driving the distal knuckle 43 to approach the lower side of the proximal knuckle 42. After reaching the limit or being blocked by the covering part, it then drives the proximal knuckle 42 to approach the lower side of the fixed seat 41, so that the combination of the proximal knuckle 42 and the distal knuckle 43 realizes the grasping restriction of the covering part. At the same time, under the action of its own weight, the covering part presses the airbag 33, so that the gas in the airbag 33 enters the corrugated pipe 35, and the corrugated pipe 35 unfolds, increasing the pressure on the short plate of the rotating plate 32, thereby making the pushing force of the short plate of the rotating plate 32 on the covering part greater.

[0049] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
