[0017] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0018] See also Figures 1 to 5The utility model provides a go / no-go gauge detection device for an insert nut, which comprises a base 1, a support plate 2, a first slide rail 3 and a cylinder 6 are symmetrically arranged on the left and right sides of the upper end of the base 1, the base and the support plate are connected by a reinforcing plate, the first slide rail 3 and the cylinder 6 are vertically arranged at the front end of the support plate 2, a slider 4 is slidably arranged on the first slide rail 3 for moving up and down, a piston rod of the cylinder 6 is connected to a connecting assembly 7 connected to the slider 4, a go / no-go gauge and a stop gauge driven by a first motor 5 are rotatably arranged on the two connecting assemblies 7, a material plate 8 that moves forward and backward by a second motor 12 is slidably arranged on the upper side of the base 1, handles are symmetrically arranged on the left and right sides of the material plate 8, and the handles are arranged to facilitate the staff to take and put the material plate, and two accommodating grooves for placing the insert nut are equidistantly provided on the upper end of the material plate 8 along its length direction, and the two accommodating grooves correspond to the go / no-go gauge and the stop gauge respectively. The second motor drives the material plate to move forward step by step. With each step, the cylinder drives the go / no-go gauge driven by the first motor to descend and then rise and reset through the connecting assembly. The go / no-go gauge detects the insert nuts in a row on the material plate. After the material plate moves forward to the bottom and the detection is completed, the material plate is picked up and turned 180 degrees and put away. The material plate then moves backward step by step. With each step, the cylinder drives the go / no-go gauge driven by the first motor to detect the insert nuts in a row on the material plate (both the go / no-go gauge and the no-go gauge detect the other side of the material plate, thereby completing the go / no-go gauge detection of the insert nuts). Then the staff removes the material plate and pours the insert nuts onto the material plate. The insert nuts will fall into the receiving groove. Replace them with new insert nuts and put them away.

[0019] A second slide rail 10 is longitudinally arranged at the upper end of the base 1, and a screw block is provided at the second slide rail 10 for sliding movement forward and backward. A displacement frame 9 with a shell is horizontally arranged at the top of the screw block, and the material plate 8 is placed in the displacement frame 9. A screw rod 11 longitudinally arranged and driven by a second motor 12 is screwed to the screw block. The second motor drives the screw rod to rotate, and the screw rod drives the screw block to move the displacement frame and the material plate forward step by step. The go and no-go gauge detects the insert nut on the material plate with each step. After the material plate moves forward to the bottom and the detection is completed, the material plate is picked up and turned 180 degrees. The material plate moves backward step by step again, and the go and no-go gauge detects the insert nut on the material plate with each step (the go and no-go gauges both detect the other side of the material plate, thereby completing the go and no-go gauge detection of the insert nut).

[0020] The number of rows of the receiving slots is greater than or equal to 6 and less than or equal to 16. Preferably, the number of rows of the receiving slots is 10.

[0021] See also Figure 1 , Figure 4 The connecting assembly 7 includes a flat plate 7.1 connected to the end of the piston rod of the cylinder 6, two vertical plates 7.2 are vertically arranged on the upper end of the flat plate 7.1, the rear side vertical plate 7.2 is connected to the slider 4, and a frame plate 7.3 is horizontally arranged on the top of the vertical plate 7.2, and the first motor 5 is downwardly arranged on the top of the frame plate 7.3.

[0022] A rotating shaft 14 is rotatably arranged at the plate 7.1, and the output shaft of the first motor 5 and the rotating shaft 14 are connected by a toothed belt 13, and the rotating shaft 14 is connected to a go gauge or a stop gauge through a coupling. Gears are keyed on the output shaft and the rotating shaft of the first motor, and the two gears are connected by a toothed belt. The go gauge and the stop gauge extend out, thereby being away from the cylinder, leaving a distance for the material plate to move forward and backward.

[0023] A protective cover 15 covering the output shaft of the first motor 5 is mounted on the vertical plate 7.2. Since the output shaft of the first motor is relatively long, the protective cover can prevent foreign matter from being involved in the output shaft of the motor.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
