Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1-2, a square lithium ion battery top cover plate flatness measuring jig has:
the supporting base plate is provided with a groove, and the groove can accommodate the square lithium ion battery top cover plate;
the first sliding rail is arranged on the supporting bottom plate;
the guide rail is arranged on the support bottom plate;
the second sliding rail is slidably arranged on the supporting bottom plate;
and the positioning mechanism can position the second slide rail.
And mounting holes are formed around the supporting bottom plate.
As shown in fig. 1, in order to implement the first embodiment of the present invention, a series of positioning holes are disposed on the guide rail, and the first slide rail is slidably mounted on the guide rail; the first slide rail and the second slide rail are positioned on the guide rail through the positioning holes. Four corners of the bottom plate for supporting are locked with the measuring plane through bolts. The supporting base plate is provided with a bolt hole matched with the limiting rod to lock and fix the top cover plate. Push another gag lever post forward along the slide rail through the manpower and push up the another side to the top cap piece, die through the bolt fastening lock and carry out the plane degree and detect.
The clamp is in the form of a bolt. The four corners of the bottom plate are fastened on the measuring table through bolts. Wherein, the narrower limiting rod is locked and fixed by a bolt in advance, and the top cover plate is clamped into a groove between the two limiting rods; fixed through the spacing muscle of bottom plate. The other limiting rod is pushed to move forward along the sliding rail and then is pushed to the other side of the top cover plate, and then the bolt is used for screwing the limiting rod for regulation. And measuring the flatness by matching with a three-coordinate measuring instrument.
As shown in fig. 2, in order to implement the second embodiment of the present invention, the first slide rail is fixedly installed on the supporting bottom plate; still have the cylinder, the cylinder is installed on supporting baseplate, and the piston rod and the second sliding rail of cylinder are connected. Four corners of the bottom plate for supporting are locked with the measuring plane through bolts. The top cover plate is clamped into the supporting base plate, one limiting rod is locked and fixed, the other limiting rod is pushed forwards along the sliding rail through air inlet of the air cylinder, and the top cover plate is completely limited by pushing the other side of the top cover plate. After the measurement is finished, the air outlet of the air cylinder returns the limiting rod. And taking out the top cover plate to finish one measurement. The whole schematic diagram of anchor clamps for adding the cylinder, accessible cylinder thrust presss from both sides tight top sheet.
Can effectively lock the top cover plate to limit and fix. And the flatness detection is accurately finished by matching with three-coordinate measuring equipment.
After adopting foretell structure, the plane degree of measurement top flap that can be accurate quick. Repeated measurement of the validation results is avoided. The measurement time is saved.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
