center positioning device

Abstract

The invention discloses a centering positioning device which comprises a supporting platform. A fixed hole is arranged on the supporting platform, a center guide seat is fixed on the fixed hole, a left guide seat and a right guide seat are arranged at two ends of the center guide seat, a left limit hole and a right limit hole are symmetrically arranged on the outer walls of two ends of the center guide seat, the bottom of the center guide seat is provided with an opening, an elastic component is fixed in the opening, the top of the elastic component is connected with a movable block, a left guide groove and a right guide groove are symmetrically arranged on the movable block, the front end of a left connecting rod penetrates through the left limit hole to be hinged to the left guide groove, the rear end of the left connecting rod is in sliding connection with the left guide seat, the front end of a right connecting rod penetrates through the right limit hole to be hinged to the right guide groove, the rear end of the right connecting rod is in sliding connection with the right guide seat, a left positioning pin and a right positioning pin are symmetrically arranged on the left connecting rod and the right connecting rod, the movable block is connected with a pull-down rope, and the pull-down rope extends out of the opening. The centering positioning device is accurate in positioning and convenient to operate, substantially reduces labor intensity of detection staff, improves efficiency, reduces energy consumption, saves cost, and is simple in structure and reasonable in arrangement.

Description

technical field [0001] The invention relates to a matching device for a checking tool, in particular to a centering and positioning device. Background technique [0002] For automotive products, such as windshields, etc., in the process of judging the deviation value and checking whether the product is qualified, the inspector needs to realize the center positioning on the inspection tool, and realize it in the form of equal positioning distance from the central axis of the product to the left and right ends position. [0003] At present, according to the accuracy requirements of the workpiece, there are positioning methods such as rulers, calipers, or electric sparks, and unilateral positioning on the inspection tool. However, the operability and accuracy of the current positioning methods The performance needs to be improved, and some positioning devices need to use oil cylinders or air cylinders as the power source, and the energy consumption needs to be reduced. Theref...
