Example 1
The present embodiment provides a conversion device, as shown in fig. 1 to 5, including a clamping mechanism 1 and a transition mechanism 2.
As shown in fig. 2, the transition mechanism 2 is matched with the clamping mechanism 1, and the clamping mechanism 1 comprises a pair of first clamping assemblies and a pair of second clamping assemblies which are vertically separated; the first clamping assembly and the second clamping assembly form a clamping space together and are used for limiting and clamping the clamping wall surface on the outer side of the workpiece in the clamping space; the transition mechanism 2 includes a pair of oppositely disposed support assemblies 21 that enter from the opening of the workpiece to grip the workpiece; the support assembly 21 is supported against the inner side wall of the workpiece to allow the clamping mechanism 1 to switch the clamping position on the clamping wall surface on the outer side of the workpiece.
Specifically, as shown in fig. 2 and 5, the support assembly 21 includes a first support head 211 and a second support head 212 disposed opposite to each other symmetrically. The first support head 211 and the second support head 212 have a third position away from each other to support the workpiece held on the inner side wall surface of the workpiece, and a fourth position switching arrangement disposed close to each other and away from the workpiece support. The opening is arranged on the non-clamping wall surface of the workpiece; in this embodiment, the vertical end surface of the workpiece has a through hole, and the first support head 211 and the second support head 212 are away from each other to be supported on the left and right inner wall surfaces of the workpiece. In addition, the clamping wall surface comprises clamping surfaces with different external dimensions, and different clamping spaces corresponding to the different clamping surfaces are formed in the clamping assembly. In this embodiment, the two ends of the transverse cross section of the "convex" workpiece are square, and have the first clamping surface 41 and the second clamping surface 42 with two sizes.
As shown in fig. 2, the clamping space enclosed by the first clamping assembly located above is smaller than the clamping space enclosed by the second clamping assembly located below. Wherein in fig. 2 the first clamping assembly is adapted to clamp a first clamping surface 41 having a smaller transverse cross-sectional dimension; similarly, the second clamping assembly is adapted to clamp a second clamping surface 42 of larger transverse cross-sectional dimension; therefore, the two vertical clamping spaces have one-to-one correspondence with workpieces with different cross-section sizes, and the stability of the clamping mechanism 1 for clamping convex workpieces is further ensured.
As shown in fig. 3 and 4, the clamping mechanism 1 includes a limiting assembly 13 disposed to avoid the transition mechanism 2, a first transition plate 151 and a second transition plate 152 disposed to face each other, and a first driver 16. In the first clamping assembly, there is a first clamping head 111 and a second clamping head 112 arranged opposite. In the second clamping assembly, there is a third clamping head 121 and a fourth clamping head 122 disposed opposite.
The two driving ends of the first driver 16 are respectively connected to the first transition plate 151 and the second transition plate 152, and drive the first transition plate 151 and the second transition plate 152 to move toward a direction approaching to or moving away from each other. The first clamping head 111 and the third clamping head 121 are vertically mounted on the ends of the first transition plate 151 and the second transition plate 152, respectively, which are relatively far away from each other; the second clamping head 112 and the fourth clamping head 122 are vertically mounted on one ends of the second transition plates 152 relatively distant from the first transition plates 151, respectively.
In addition, two ends of the limiting component 13 are rotatably installed on the first clamping head 111 and the second clamping head 112 through a first rotating shaft 141 and a second rotating shaft 142 respectively, for example, in a hinged connection manner, the first rotating shaft 141 and the second rotating shaft 142 are fixed on one ends, close to each other, of the first transition plate 151 and the second transition plate 152 respectively; meanwhile, a first connection line is formed between the first and second rotating shafts 141 and 142. The limiting component 13 is arranged in a conversion way between a first position which is overlapped with the first connecting line and a second position which is formed by the limiting component 13 and the first connecting line in a triangular shape; the stop assembly 13 is adapted to abut on the top or bottom of a workpiece located in the clamping space in the second position.
In the conversion device with the structure, when the limit component 13 is overlapped with the first connecting line, the distance between the first clamping head 111 and the second clamping head 112 is adjusted to be the maximum; when the limit component 13 and the first connecting line are overlapped to form a triangle, the distance between the first clamping head 111 and the second clamping head 112 is gradually reduced from large to small, so that the size of a clamping space formed by the two clamping heads is adjusted, and the clamping component is suitable for clamping workpieces with different sizes; meanwhile, when the limiting component 13 is at the second position, the limiting component 13 and the first connecting line form a triangle, besides the first connecting line, the other two sides of the triangle horizontally extend into the clamping space, and the bottom of the workpiece in the clamping space is supported or the top of the workpiece is limited, so that the vertical direction of the workpiece is accurately limited or positioned while the size of the clamping space of the clamping component is adjustable, the clamping component is simple in structure and high in reliability, and the problem of inaccurate positioning caused by vertical movement of the workpiece is prevented.
In the clamping mechanism 1 of the present embodiment, as shown in fig. 3, the limiting assembly 13 includes a first limiting member 131, a second limiting member 132, and a third rotating shaft 133 located between the first limiting member 131 and the second limiting member 132. Specifically, the third rotating shaft 133 is located outside the first clamping head 111 and the second clamping head 112, and the third clamping head 121 and the fourth clamping head 122; one end of the first limiting member 131 and one end of the second limiting member 132, which are close to each other, are rotatably mounted on the third rotating shaft 133, and one end, which is far away from each other, are rotatably mounted on the first rotating shaft 141 and the second rotating shaft 142, respectively. For example, the arm lengths of the first limiting part 131 and the second limiting part 132 are the same, so that when the limiting assembly 13 is in the second position, the vertical center plane of the workpiece clamped in the clamping space and the center line where the third rotating shaft 133 is located are overlapped, and the stability of the clamping action of the clamping mechanism 1 is further ensured.
In the actual use process, when the limiting assembly 13 is at the second position, as shown in fig. 2, the third rotating shaft 133 is located in the clamping space, and the first limiting member 131 and the second limiting member 132 are respectively used as two sides of the triangle, and extend horizontally from the first connecting line to the third rotating shaft 133 located in the clamping space.
