[0024] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.

[0025] The measuring tool for detecting the appearance of a lock tongue comprises a measuring tool seat 1, a tongue depressor 2 and a micro switch 3. The micro switch 3 is mounted on the measuring tool seat 1. The tongue depressor 2 and the measuring tool seat 1 are movably assembled. The measuring tool seat 1 has a measuring tool groove, which is used to place the lock tongue member 5. The lock tongue member 5 comprises a locking plate 51, a lock connecting rod 52 and a lock outer rod 53. The locking plate 51, the lock connecting rod 52 and the lock outer rod 53 are arranged in sequence. The measuring tool groove comprises a plate measuring groove 11 and a rod measuring groove 12. The plate measuring groove 11 and the rod measuring groove 12 are connected. The plate measuring groove 11 is used to place the locking plate 51. The rod measuring groove 12 is used to place the lock connecting rod 52. The tongue depressor 2 is used to slide to cover the rod measuring groove 12 under the driving force. The lock outer rod 53 is arranged correspondingly to the micro switch 3. The lock outer rod 53 is used to swing and close the micro switch 3.

[0026] When the lock tongue shape detection gauge is used to detect the lock tongue shape, the lock tongue piece 5 is placed in the gauge groove. At this time, the lock plate 51 is in the plate measuring groove 11, the lock link 52 is in the rod measuring groove 12, and the lock outer rod 53 is arranged corresponding to the micro switch 3. Then, the tongue pressing piece 2 is driven to move until the tongue pressing piece 2 covers the rod measuring groove 12, and the lock link 52 is restricted from leaving the rod measuring groove 12 by the tongue pressing piece 2. Then, downward pressure is applied to the lock plate 51 to cause the lock link 52 to rotate and drive the lock outer rod 53 to swing; if the lock link 52 is in the measuring groove 12, the lock outer rod 53 is rotated. The swing of rod 52 causes the micro switch 3 to be in a closed state, releases the downward pressure of the lock plate 51, and the lock link 52 rebounds and resets, then the inspection result of the lock tongue member 5 is a qualified product. On the contrary, if the lock link 52 has completed its swing and the micro switch 3 is still in an open state, then the inspection result of the lock tongue member 5 is an NG product. In this way, the structure of the inspection tool is simple and the cost is low. At the same time, the appearance inspection operation is simple and convenient. The micro switch 3 quickly responds to the inspection result, which greatly improves the efficiency of the appearance inspection of the lock tongue member 5.

[0027] The lock tongue shape detection gauge includes a piece measuring column 4, which is arranged to extend vertically. The piece measuring column 4 is installed on the measuring tool seat 1, and the piece measuring column 4 is pressed and arranged downward; the piece measuring column 4 extends to the piece measuring groove 11, and the locking piece 51 is used to apply downward pressure to the piece measuring column 4.

[0028] In this way, after placing the lock tongue piece 5, under the action of the sheet measuring column 4, the lock plate 51 is supported, which is convenient for loading the lock tongue piece 5. Then, downward pressure is applied to the lock plate 51 to drive the lock link 52. After the downward pressure on the lock plate 51 is cancelled, the sheet measuring column 4 is reset upward to facilitate the removal of the lock tongue piece 5.

[0029] The locking plate 51 can be pressed manually to swing the locking plate 51 and trigger the micro switch 3; or the locking plate 51 can be pressed manually to swing the locking plate 51 and trigger the micro switch 3; or the locking plate 51 can be pressed manually by an automatic pressing part such as a pressing cylinder or a punch to apply the pressing force, which saves time and effort.

[0030] The lock tongue shape detection gauge includes a column spring, the lower part of which is fixedly arranged with the gauge seat 1, and the upper part of which is docked with the sheet measuring column 4. The column spring is used to reset the sheet measuring column 4 upward, and the elastic force of the column spring is greater than the self-weight of the lock sheet 51.

[0031] In this way, when the lock tongue piece 5 is loaded onto the measuring tool seat 1, the self-weight of the locking piece 51 will not cause the piece measuring column 4 to move. Only when downward pressure is applied to the lock piece 51, the downward pressure overcomes the elastic force of the column spring. At this time, the piece measuring column 4 moves downward, thereby driving the lock link 52 to swing and causing the micro switch 3 to be in a closed state. After detection, when the downward pressure on the lock piece 51 is cancelled, under the action of the column spring, the piece measuring column 4 returns to an upward position, causing the lock piece 51 to swing upward, thereby facilitating the retrieval of the lock tongue piece 5.

[0032] The measuring tool seat 1 has a column groove, which is arranged to extend longitudinally. The lower part of the sheet measuring column 4 is embedded in the column groove, and the column groove is used to limit the radial deviation of the sheet measuring column 4.

[0033] In this way, under the action of the column groove, a limiting effect is exerted on the sheet measuring column 4, so as to prevent the sheet measuring column 4 from radially deviating when moving, thereby ensuring that the sheet measuring column 4 moves vertically and increasing the service life.

[0034] The top of the sheet measuring column 4 is arranged in an arched arc shape, which reduces the reverse force of the sheet measuring column 4 and prevents the locking piece 51 from being compressed and deformed, thereby protecting the locking piece 51 .

[0035] The tongue depressor 2 includes a transverse pressure plate 21 and a longitudinal movement plate 22. The transverse pressure plate 21 is stacked with the measuring tool seat 1. The outer end of the transverse pressure plate 21 is connected to the upper part of the longitudinal movement plate 22. The lower part of the longitudinal movement plate 22 extends downward to correspond to the measuring tool seat 1. The longitudinal movement plate 22 is used to receive the driving force to drive the inner end of the transverse pressure plate 21 to cover the rod measuring groove 12.

[0036] In this way, with the cooperation of the transverse pressure plate 21 and the longitudinal movement plate 22, the covering and opening of the rod measuring slot 12 are achieved. When performing inspection, the driving force is applied by the longitudinal movement plate 22 to prompt the transverse pressure plate 21 to move to cover the rod measuring slot 12. In this way, under the action of the transverse pressure plate 21, the locking link 52 is prevented from accidentally disengaging from the rod measuring slot 12 during rotation, thereby ensuring normal inspection operations.

[0037] The tongue depressor 2 includes a transverse fixing rod 24 and two transverse limiting rods 25, and the transverse fixing rod 24 is arranged between the two transverse limiting rods 25; the transverse pressure plate 21 has a transverse fixing groove and two transverse limiting grooves, and the transverse fixing groove and the transverse limiting groove are respectively extended along the radial direction of the transverse fixing rod 24, and the transverse fixing groove is arranged between the two transverse limiting grooves. The transverse fixing rod 24 extends through the transverse fixing groove to the measuring tool seat 1, and the transverse limiting rod 25 extends through the transverse limiting groove to the measuring tool seat 1.

[0038] In this way, under the cooperation of the transverse fixing rod 24 and the two transverse limiting rods 25, the movement of the transverse pressure plate 21 is guided and restricted, the movement accuracy of the transverse pressure plate 21 is improved, and the transverse pressure plate 21 is ensured to move in a straight line.

[0039] When the transverse rod 24 is at the inner end of the transverse groove, the transverse pressure plate 21 and the rod measuring groove 12 are arranged in a staggered manner. When the transverse rod 24 is at the outer end of the transverse groove, the transverse pressure plate 21 covers the rod measuring groove 12.

[0040] In this way, through the cooperation between the transverse fixing rod 24 and the transverse fixing groove, and the cooperation between the transverse limiting rod 25 and the transverse limiting groove, the moving stroke of the transverse pressure plate 21 is limited, ensuring accurate covering of the rod measuring groove 12 and accurate opening of the rod measuring groove 12.

[0041] The tongue depressor 2 includes two longitudinal limit rods 23, which are arranged at intervals and correspondence, and the outer ends of the longitudinal limit rods 23 are arranged to be butt-jointed with the longitudinal displacement plate 22, and the inner ends of the longitudinal limit rods 23 are movably embedded with the measuring tool seat 1; under the action of the two longitudinal limit rods 23, the movement of the longitudinal displacement plate 22 is more stable, thereby making the movement of the transverse pressure plate 21 more stable.

[0042] The tongue depressor 2 includes a drive plate motor, which is installed on the measuring tool seat 1 and arranged corresponding to the longitudinal movement plate 22. The drive plate motor has a motor shaft, which is connected to the longitudinal movement plate 22 and arranged between the two longitudinal limit rods 23.

[0043] In this way, the driving force is applied by the driving plate motor to cause the longitudinal moving plate 22 to be arranged to move, thereby driving the transverse pressing plate 21 to be arranged to move, so that the transverse pressing plate 21 covers the rod measuring slot 12 or opens the rod measuring slot 12.

[0044] The micro switch 3 includes a switch body 31, a micro head 33 and a micro piece 32. The switch body 31 is mounted on the measuring tool seat 1, and the switch body 31 is arranged tilted. The micro head 33 and the micro piece 32 are respectively mounted on the switch body 31. The lock outer rod 53 is arranged corresponding to the micro piece 32. The lock outer rod 53 swings to drive the micro piece 32 to swing. The micro piece 32 is arranged corresponding to the micro head 33. The micro piece 32 is subjected to the pressing force of the lock outer rod 53 to swing and press the micro head 33.

[0045] In this way, during the detection operation, if the lock link 52 swings to cause the micro-movement plate 32 to swing and press against the micro-movement head 33, the detection result of the lock tongue member 5 is a qualified product; on the contrary, if the lock link 52 has completed its swing and the micro-movement plate 32 is still separated from the micro-movement head 33, it is an NG product.

[0046] The micro-moving piece 32 includes an inner moving piece and an outer moving piece. The inner end of the inner moving piece is connected to the switch body 31, and the outer end of the inner moving piece is extended in a direction perpendicular to the switch body 31, and the outer end of the inner moving piece is butt-jointed with one end of the outer moving piece, and the other end of the outer moving piece is obliquely extended in a direction away from the switch body 31, and the outer moving piece is correspondingly arranged with the micro-moving head 33.

[0047] In this way, the lock link 52 swings to be arranged in vertical contact with the outer movable plate, which is convenient for driving the outer movable plate to press the micro-movement head 33 and facilitates the appearance detection of the lock tongue member 5.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
