Description

Technical Field

[0001] The utility model relates to the field of error-proof detection equipment, and particularly relates to an error-proof clamping detection device. Background Art

[0002] During the welding process of the battery box, there are two small sleeve parts with the same installation position but different sizes, and the sleeve thickness deviation is 2 mm. The parts are placed manually. If the sleeve position is placed wrongly, the entire assembly part will be scrapped after welding on the assembly part, resulting in a large loss. The magnetic switch on the cylinder can monitor the signal of whether the clamping is in place, but its sensitivity cannot ensure the error-proof of the parts. Summary of the Invention

[0003] In view of this, the utility model aims to provide an error-proof clamping detection device, which enlarges the detection range by means of force arm amplification to achieve the purpose of preventing parts from being installed wrongly.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0005] An error-proof clamping detection device includes a fixed base, a mounting plate and a sleeve to be detected. The mounting plate is mounted on the fixed base, and a clamping cylinder, a hinge and a sensor fixing bracket are mounted on the mounting plate;

[0007] A pair of opposed sensors are mounted on the sensor fixing bracket, a force arm amplification block is mounted on the hinge, and the left side of the force arm amplification block is located between the pair of opposed sensors;

[0008] A detection small hole is provided on the left side of the force arm amplification block, and a clamp head is mounted on the force arm amplification block, and the clamp head clamps the sleeve to be detected.

[0009] Further, a connecting head is connected to the clamping cylinder, and the connecting head passes through the mounting plate and is connected to the bottom of the force arm amplification block.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The error-proof clamping detection device of the utility model converts the detection of a small distance into the detection of a large displacement range by means of the principle of lever amplification of small-size part deviation, that is, through the force arm amplification block, and can realize the error-proof effect without using a high-cost high-precision laser sensor, and can avoid the part deviation caused by wrongly installed and welded parts.

[0018] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "back", etc. is based on the orientation or positional relationship shown in the attached drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] The present utility model will be described in detail below with reference to the attached drawings and in combination with the embodiments.

[0020] This embodiment relates to an anti-misoperation clamping detection device, which can magnify the detection range through the way of force arm amplification to achieve the purpose of preventing parts from being misassembled.

[0021] Based on the above design concept, an exemplary structure of the anti-misoperation clamping detection device in this embodiment is as Figure 1-2As shown in the figure, it mainly includes a fixed base 1, a mounting plate 2, and a sleeve 4 to be detected. The mounting plate 2 is installed on the fixed base 1. A clamping cylinder 5, a hinge 3, and a sensor fixing bracket 6 are installed on the mounting plate 2. The clamping cylinder 5 is installed at the left bottom of the mounting plate 2 through a connector. The hinge 3 is installed at the right bottom of the mounting plate 2. The sensor fixing bracket 6 is installed at the left bottom of the mounting plate 2. A pair of opposed sensors 7 are installed on the sensor fixing bracket 6. A force arm amplification block 8 is installed on the hinge 3. The left side of the force arm amplification block 8 is located between the pair of opposed sensors 7. A detection hole is provided on the left side of the force arm amplification block 8. A clamp head 9 is installed on the force arm amplification block 8. The clamp head 9 clamps the sleeve 4 to be detected.

[0022] A connector is connected to the clamping cylinder 5. The connector passes through the mounting plate 2 and is connected to the bottom of the force arm amplification block 8. It can be understood that the opposed sensors 7 are connected to the PLC through wires to facilitate signal transmission.

[0023] When the anti-misloading clamping detection device described in this embodiment is in use, after the part completed in the previous process is placed on the clamping cylinder 5 by the robot, the operator places the sleeve 4 to be detected and then walks out of the safety light curtain area. The operator presses the reset and start buttons. The part is clamped, and the clamp head 9 clamps the sleeve 4 to be detected. When a short sleeve 4 to be detected is misloaded, the position of the clamp head 9 will be low after clamping. The low displacement is amplified through the hinge 3 and transmitted to the force arm amplification block 8. The detection hole on the force arm amplification block 8 deviates from the position of the opposed light source of the opposed sensors 7 at this time, that is, the sensor is blocked, and the corresponding sensor induction signal is lost. An error of misloaded parts is set in the PLC. When loading parts normally, the position of the clamp head 9 is normal, the position of the detection hole on the force arm amplification block 8 is also normal, the light source of the opposed sensors 7 can pass through the detection hole, and the sensor induction signal is normal. It is determined that the part is loaded correctly under the clamping condition.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
