Embodiment Construction

[0021] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the sealing ring assembly detection device includes a positioning seat 4 for mating with the piston cylinder 19 to realize the positioning of the detection device. A slider 3 is slid in the middle of the positioning seat 4 along its radial direction. The front part is fixedly installed with a detection arm 7 that protrudes from the positioning seat 4 and moves synchronously with the slider 3. On the detection arm 7, two main probes for detecting the sealing ring extending radially along the positioning seat 4 are installed. The main probes are the first probe 12 and the second probe 15, the first probe 12 and the second probe 15 are arranged in sequence along the axial direction of the detection arm 7, the number of the main probes and its axial direction of the detection arm The position and spacing correspond to the number of sealing rings 18 to be tested in the piston cylinder and their positions and sp...

Abstract

The invention discloses a device for detecting assembly of sealing rings. The device comprises a positioning base for being matched with a piston cylinder through insertion to position the device, wherein a slider is radially assembled in the middle of the positioning base in a sliding manner; a feeler arm which stretches out of the positioning base and synchronously acts with the slider is fixedly installed in front of the slider; at least a main probe which radially extends along the positioning base and is used for detecting the sealing rings is installed on the feeler arm; the main probesare axially arranged in parallel along the feeler arm; the number of the main probes and the space between the main probes in the axial direction of the feeler arm correspond to the number of the sealing rings to be detected in the piston cylinder and the space between the sealing rings in the axial direction of the piston cylinder; main sensors correspondingly connected with the main probes are also installed on the feeler arm; and the signal output ends of the main sensors are connected with a transmission circuit for transmitting signals. The device has the following beneficial effect: whether the sealing rings in the piston cylinder are installed in place can be conveniently detected by the device, thus effectively putting an end to missing of the sealing rings and improving the assembly quality and efficiency of the products.

Description

technical field [0001] The invention relates to a sealing ring assembly detection device. Background technique [0002] At present, the piston cylinder of the commonly used hydraulic or pneumatic disc brake is slidably equipped with a piston, and a plurality of ring grooves are arranged on the inner wall of the piston cylinder along the axial direction of the piston cylinder. The sealing ring that is tightly matched with the piston cylinder, the main function of the sealing ring is to prevent leakage and dust. The original piston cylinder assembly work is performed by a single person in batches. When installing the sealing ring in the piston cylinder, because the work is a simple repetitive action, the operator repeats the operation for a long time, which is prone to mental fatigue and paralysis in thinking, resulting in internal damage to the piston cylinder. The sealing ring is missing, and because the sealing ring is installed in the ring groove on the inner wall of the ...
