Claw height synchronous detection device for product with multiple bending claws

Abstract

The invention discloses a claw height synchronous detection device for a product with multiple bending claws. The claw height synchronous detection device is characterized in that a first mounting plate, a second mounting plate and a third mounting plate are sequentially arranged from top to bottom, the first mounting plate is fixed to a sliding table mechanism and performs synchronous vertical linear reciprocating motion along with the sliding table mechanism, the upper end of an end face feedback mechanism is elastically connected with the first mounting plate, the second mounting plate andthe third mounting plate are fixed to the middle and the lower portion of the end face feedback mechanism respectively, eddy current digital displacement sensors are vertically fixed to the second mounting plate in a penetrating mode, claw height feedback mechanisms are elastically connected with the third mounting plate, and the claw height feedback mechanisms, bending claws and the eddy currentdigital displacement sensors are in one-to-one correspondence. Through the cooperation of the claw height feedback mechanisms and the end face feedback mechanism, the claw height of the product with multiple bending claws can be synchronously detected, and the detected displacement change is equivalently transmitted to the eddy current digital displacement sensors, so that the stability and accuracy of the transmitted displacement change amount are ensured.

Description

technical field [0001] The invention relates to a device for detecting the claw height of a product with bending claws, in particular to a device for synchronously detecting the claw height of a product with multiple bending claws. Background technique [0002] figure 1 As shown in the product, its side claw 1-1 is formed by bending figure 2 For bending claws 1-2 with a height h shown in , if the bending fixture is worn or foreign matter is attached to the surface of the claws, the bending size of the claws will be poor after bending. Since the size fluctuation range is very small, it cannot be effectively observed by human eyes. In order to prevent defective products from flowing out, it is necessary to detect the height of the rear claw after bending. [0003] High-speed, high-precision eddy current digital displacement sensors are usually used for detection, but when it is necessary to detect the claw height at the same time for smaller products with multiple bending c...

[0003] High-speed, high-precision eddy current digital displacement sensors are usually used for detection, but when it is necessary to detect the claw height at the same time for smaller products with multiple bending claws, since the sensor needs to be installed with a distance between the sensors, It needs to occupy a large installation space, so that multiple sensors cannot effectively touch the product bending claws after being fixed, so it is difficult for the existing detection device to synchronize multiple bending claws on small detection products, quickly, stably, Accurate detection
