Detailed Description
A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The scope of the invention is not limited to the following examples, but is intended to be limited only by the appended claims and the equivalents and modifications thereof, which fall within the scope of the invention.
Referring to fig. 1-4, the clamping and positioning mechanism according to the present invention includes a fixed panel 1, the fixed panel has two opposite side surfaces and an end surface located between the two side surfaces, one side of one end surface of the fixed panel is provided with a cylinder 2, the other opposite side is provided with a U-shaped groove 3 forming an obtuse angle with the end surface, and the opening of the U-shaped groove faces outwards and forms a first clamping part; a positioning panel 4 is arranged on the two side surfaces of the fixed panel and positioned on the inner side of the first clamping part respectively, and the two positioning panels form a second clamping part; the positioning panel is provided with a second limiting groove 5, the inner end of the second limiting groove is linear, and the outer end of the second limiting groove is bent outwards to form an obtuse included angle with the inner side of the second limiting groove; a movable panel 6 is arranged in the first clamping part and the second clamping part, a linear first limit groove 7 is arranged at the inner end of the movable panel, and the first limit groove is parallel to the inner end of the second limit groove; a first lock pin 8 is movably arranged in the first limit groove, and two ends of the first lock pin are respectively fixed on two side surfaces of the first clamping part; the outer end of the movable panel is fixedly provided with a second lock pin 9, and two ends of the second lock pin are respectively and movably limited in second limit grooves of the two positioning panels; the inner side of the movable panel is provided with a clamping positioning block 11 for clamping and positioning the workpiece 10, and the outer side of the movable panel is fixedly connected with a piston rod of the cylinder.
The U-shaped groove is formed by extending outwards from two side surfaces of the fixed panel respectively; the inner side of the positioning panel is fixed on the fixing panel through bolts; one side of one end face of the fixed panel extends outwards to form a cylinder fixing seat 12, and the base of the cylinder is fixed on the cylinder fixing seat.
When the clamping and positioning mechanism is in an initial state, referring to fig. 1-2, a piston rod of the cylinder is retracted into the cylinder, so that the movable panel 6 is pulled to retract into the positioning panel 4, at the moment, the first lock pin 8 is arranged at the outermost end of the first limiting groove 7, the second lock pin 9 is arranged at the innermost end of the second limiting groove, and the clamping and positioning block 11 for clamping and positioning the workpiece 10 is far away from the workpiece 10. When the workpiece 10 needs to be clamped and positioned, the cylinder is started, the piston rod of the cylinder extends outwards and pushes the movable panel 6 to move outwards together, the second lock pin 9 moves along the second limit groove 5 of the positioning panel 4 when the movable panel 6 moves outwards, the first limit groove 7 moves along the first lock pin 8, the inner end of the second limit groove is linear, the outer end of the second limit groove is outwards bent to form an arc, and the first limit groove is linear, so that when the piston rod moves to the maximum position of the stroke, the movable panel 6 is driven to move outwards to the maximum stroke, finally the first lock pin reaches the innermost end of the first limit groove, the second lock pin reaches the outermost end of the second limit groove, and the clamping and positioning block 11 moves obliquely outwards to the surface of the workpiece 10, so that the workpiece 10 is positioned and clamped, and the workpiece is clamped, see fig. 3-4.
Therefore, the outer end of the second limiting groove of the fixed panel is outwards bent to form an arc, and at the moment, even if the air cylinder does not work, the second lock pin has a force facing the direction vertical to the inner wall of the second limiting groove due to the reaction force of the workpiece to the movable panel, and at the moment, the second limiting groove has a locking effect on the second lock pin, so that the clamping positioning block is prevented from outwards loosening or resetting under the reaction of the workpiece, and the stability of the clamping state of the workpiece is ensured.
