Abstract
Description
Technical Field
[0001] The utility model relates to a clamping device of process equipment, and in particular to a clamping device with a pivotable clamping block. Background Art
[0002] The existing clamping device is arranged on a process equipment to clamp the plate. Figure 1 The conventional clamping device 100 shown in the figure includes a connecting rod 10 and a clamp 12, wherein the clamp 12 includes a first clamping member 14, a second clamping member 16 and a torsion spring (not shown). The first clamping member 14 and the second clamping member 16 respectively have a clamping end 142, 162. The torsion spring is sleeved on the connecting rod 10 and abuts against the first clamping member 14 and the second clamping member 16. The two clamping ends 142, 162 respectively have a clamping surface 142a, 162a for clamping the plate.
[0003] like Figure 1 As shown in FIG. 1 , when the clamped plate is a thin plate P1, the contact area between the clamping surfaces 142a, 162a of each clamping end 142, 162 and the surface of the thin plate P1 is larger, so the thin plate P1 can be clamped more stably. However, as the thickness of the clamped plate increases, the contact area between the clamping surfaces 142a, 162a of each clamping end 142, 162 and the surface of the plate will be relatively reduced. For example, Figure 2 As shown, when the clamped plate is a thick plate P2, the distance between the two clamping ends 142 and 162 increases, and the clamping surfaces 142a and 162a will form an angle with the surface of the thick plate P2, so that the contact area will be reduced, making it difficult to stably clamp the thick plate P2. In addition, due to the reduced contact area, the stress of the clamping ends 142 and 162 acting on the thick plate P2 will be relatively increased, which may cause damage to the thick plate P2.
[0004] Therefore, the design of the existing clamping device 100 is still not perfect and needs to be improved. Utility Model Content
[0005] In view of this, an object of the present invention is to provide a clamping device that can stably clamp a plate.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a clamping device, comprising a connecting rod and at least one clamp, wherein the at least one clamp includes a first support member, a second support member, a first clamping block and a second clamping block, wherein the first support member and the second support member are relatively rotatably arranged on the connecting rod, the first support member has a first end, the second support member has a second end, and the second end corresponds to the first end; the first clamping block is pivoted at the first end, the first clamping block has a first clamping surface, the second clamping block is pivoted at the second end, the second clamping block has a second clamping surface, and the second clamping surface faces the first clamping surface.

Each of the second side boards 38 has a second sleeve hole 382, and the second sleeve hole 382 of the two second side boards 38 is for the connecting rod 20 to pass through. In this embodiment, the second end 342 of the second support member 34 is located at the bottom of the second support member 34, and the two second side boards 38 are provided with a second shaft rod 40 at the second end 342. The second clamping block 54 is provided at the second end 342 of the second support member 34 through the second shaft rod 40, and the second clamping block 54 can pivot at the second end 342. The second shaft rod 40 is parallel to the first shaft rod 30.
[0094] Each of the second side plates 38 has a second through hole 384 at the second end 342. The second clamping block 54 is located between the two second side plates 38. The second clamping block 54 has an axial hole 542, and the axial hole 542 corresponds to the two second through holes 384. The second shaft rod 40 passes through the second through holes 384 of the two second side plates 38 and the axial hole 542 of the second clamping block 54, so that the second clamping block 54 is set on the second shaft rod 40. The two ends of the second shaft rod 40 respectively have a second annular groove 402, and the two second annular grooves 402 are respectively located on the outer sides of the two second side plates 38. A buckle 42 is sleeved on each of the second annular grooves 402, and the buckle 42 is a C-shaped buckle. The second shaft rod 40 can be positioned on the two second side plates 38 by the buckle rings 42 arranged at the two ends of the second shaft rod 40. The second clamping block 54 can pivot relative to the second shaft 40 , or the second shaft 40 can rotate relative to the two second side plates 38 , both of which can achieve the purpose of the second clamping block 54 being able to pivot at the second end 342 of the second support member 34 .
[0095] The second clamping block 54 has a second clamping surface 56, a second back surface 58, a second upper chamfer 60 and a second lower right angle 62. The second clamping surface 56 faces the first clamping surface 46 of the first clamping block 44. The second clamping surface 56 is used to contact the other surface of the plate P1. The second clamping surface 56 has a second anti-slip structure 562. In this embodiment, the second anti-slip structure 562 includes a plurality of second protruding teeth 562a. Each of the second protruding teeth 562a is elongated, and the extension direction of each of the second protruding teeth 562a is parallel to the second shaft 40. The plurality of second protruding teeth 562a are arranged in parallel and arranged from top to bottom. When the first clamping surface 46 contacts the second clamping surface 56, the tooth peaks of each of the first protruding teeth 462a contact the tooth peaks of each of the second protruding teeth 562a.
[0096] The second back surface 58 faces the second main board 36 and faces away from the second clamping surface 56. The second upper chamfer 60 is connected to the upper edge of the second back surface 58, and the second lower right angle 62 is connected to the lower edge of the second back surface 58. A gap G2 is provided between the second back surface 58 and the second main board 36 to facilitate the pivoting of the second clamping block 54. In this embodiment, the second upper chamfer 60 is a circular chamfer. Through the second upper chamfer 60, the second clamping block 54 can have a larger rotation angle when rotating upward; through the second lower right angle 62, the rotation angle of the second clamping block 54 when rotating downward can be limited.
[0097] In this embodiment, the clamp 22 may further include an elastic member 64, and the elastic member 64 is used to provide elastic force to the first support member 24 and the second support member 34, so that the first clamping surface 46 of the first clamping block 44 and the second clamping surface 56 of the second clamping block 54 are close to each other. The elastic member 64 may be a torsion spring, and the elastic member 64 is sleeved on the connecting rod 20 and located between the two first side plates 28 of the first support member 24, and the two ends of the elastic member 64 are respectively against the first main board 26 of the first support member 24 and the second main board 36 of the second support member 34.
[0098] Please cooperate Fig. 9 When in use, by applying force to the upper ends of the first support member 24 and the second support member 34, the first clamping surface 46 of the first clamping block 44 and the second clamping surface 56 of the second clamping block 54 can be moved away from each other to form a clamping space for the plate to pass through. After the force is released, the first clamping surface 46 and the second clamping surface 56 respectively abut against the two opposite surfaces of the plate P1 to clamp the plate P1. Since the first clamping block 44 and the second clamping block 54 can pivot, the first anti-slip structure 462 of the first clamping surface 46 will abut against the surface of the plate P1, and the second anti-slip structure 562 of the second clamping surface 56 will abut against the other surface of the plate P1, thereby increasing the contact area to stably clamp the plate P1.
[0099] In addition Fig.10 When a thicker plate P2 needs to be clamped, since the first clamping block 44 and the second clamping block 54 can pivot, the first clamping surface 46 and the second clamping surface 56 will deflect according to the distance between the two surfaces of the thick plate P2 to be the same as Fig. 9 The contact area is against the surface of the thick plate P2. Therefore, the thick plate P2 can also be stably clamped.
[0100] If the panels P1 and P2 are tilted, the first clamp block 44 and the second clamp block 54 can also pivot accordingly to clamp the tilted panels P1 and P2. When the panels P1 and P2 are vertical due to gravity, the first clamp block 44 and the second clamp block 54 can pivot back to the original position. Fig. 9 or Fig.10 Position shown.
[0101] Therefore, the clamping device 1 of this embodiment can effectively improve the defect of the existing clamping device that excessive stress concentration is formed when clamping thick plates.
[0102] In addition, the clamping device 1 may optionally include at least one positioning member 66, and in this embodiment, two positioning members 66. Each positioning member 66 is non-rotatably disposed on the connecting rod 20, for example, welded on the connecting rod 20. Each positioning member 66 is located between the first side plate 28 of the first support member 24 of each clamp 22 and the second side plate 38 of the second support member 34 in the radial direction of the connecting rod 20. When each clamp 22 deflects, the deflection angle of each clamp 22 can be limited by each positioning member 66.
[0103] Please cooperate Figures 11 to 13 , is the clamping device 2 of the second preferred embodiment of the utility model, which has a structure substantially the same as that of the first embodiment, except that, in the present embodiment, the first clamping block 44a has a first lower chamfer 68, which is connected to the lower edge of the first back side 48, and the first lower chamfer 68 is a circular arc chamfer; the second clamping block 54a has a second lower chamfer 70, which is connected to the lower edge of the second back side 58, and the second lower chamfer 70 is a circular arc chamfer.
[0104] The first lower chamfer 68 allows the first clamping block 44a to have a larger rotation angle when it rotates downward; and the second lower chamfer 70 allows the second clamping block 54a to have a larger rotation angle when it rotates downward.
[0105] like Fig.11 As shown, when the plate P3 has a deflected section, the first clamping surface 46 and the second clamping surface 56 can be deflected accordingly and clamp the deflected section of the plate P3. Fig.12 As shown, when one surface of the plate P4 extends straight, the first clamping surface 46 can make straight contact; when the other surface of the plate P4 extends obliquely, the second clamping surface 56 can also make oblique contact accordingly. Fig.13 As shown, when both surfaces of the plate P5 extend obliquely, the first clamping surface 46 and the second clamping surface 56 can be in contact with each other in an oblique manner accordingly.
[0106] The above description is only a preferred feasible embodiment of the present utility model. Any equivalent changes made by applying the specification and claims of the present utility model should be included in the patent scope of the present utility model.
