The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following embodiments, features of the embodiments may be combined with each other without conflict.
Referring to fig. 1 and 4, an embodiment of the present invention provides a positioning device 100 for positioning a first workpiece 200 and a second workpiece 300.
Referring to fig. 5, the positioning apparatus 100 includes a base 10, a driving member 20, a first clamping block 30 and a second clamping block 40. The driving member 20 is disposed on the base 10. The driving element 20 drives the first clamping block 30 and the second clamping block 40 to clamp and position the first workpiece 200; the first clamping block 30 or the second clamping block 40 also supports against one side of the second workpiece 300 to position the second workpiece.
Referring to fig. 2 and 3, in the illustrated embodiment, the driving member 20 is a finger-clamping cylinder, and includes a body 21 and two driving rods 22 disposed on the body 21. One of the driving rods 22 is connected to the first clamping block 30, and the other driving rod 22 is connected to the second clamping block 40. The body 21 drives the two driving rods 22 to drive the first clamping block 30 and the second clamping block 40 to approach or separate from each other.
It is understood that in other embodiments, the driving member 20 may be a single-shaft air cylinder, a motor screw module, a linear motor, or the like. In other embodiments, the first clamping block 30 and the second clamping block 40 may be one of the two blocks connected to the driving member 20, and the other one of the two blocks kept fixed.
The first clamping block 30 includes a first connecting portion 31, a first mounting portion 32, and a first clamping portion 33. The first connecting portion 31 is vertically connected to the first mounting portion 32. The first clamping portion 33 is provided on the first mounting portion 32. The second clamping block 40 has a structure similar to that of the first clamping block 30. The second clamping block 40 includes a second connecting portion 41, a second mounting portion 42, and a second clamping portion 43. The second connecting portion 41 is vertically connected to the second mounting portion 42. The second clamping portion 43 is provided on the second mounting portion 42.
The first connecting portion 31 is fixedly connected to the driving rod 22. The second connecting portion 41 is fixedly connected to the other driving rod 22. The first clamping portion 33 and the second clamping portion 43 are used for clamping the first workpiece 200 and pushing against the second workpiece 300.
When the first clamping block 30 and the second clamping block 40 approach each other, the first mounting portion 32 abuts against the second mounting portion 42 to maintain the distance between the first clamping portion 33 and the second clamping portion 43.
