When the length from the first sensor 63 to the top surface is not greater than the set length, the first sensor 63 receives a signal from the top surface, indicating that the positioning boss 69 and the positioning groove 53 complete positioning, guiding the operation state of the driving structure (the above-mentioned telescopic driving member 11) for driving the pin shaft assembly 6, and the linear driving member 62 can drive the pin shaft 68 to be inserted into the pin shaft hole 52. Wherein the set length is the detection range of the first sensor 63.
The top surface as described herein is the surface of the latch boss 54 that the positioning boss 69 first passes relative to the direction of movement of the positioning boss 69. That is, when the positioning boss 69 is positioned in the positioning groove 53 from the top down, the top surface is the upper surface of the latch seat 54; the top surface is the left side of the latch seat 54 when the positioning boss 69 is positioned in the positioning slot 53 from left to right.
Further, when the positioning groove 53 is a rectangular groove, the top surface is parallel to the bottom wall surface of the positioning groove 53, and the positioning boss 69 is positioned in the positioning groove 53, the distance from the first sensor 63 to the top surface is not greater than the set length, and the detection is accurate.
In another embodiment, the sensor assembly further includes a second sensor 65 and a third sensor 66, the second sensor 65 and the third sensor 66 being used to determine the positional status of the pin 68. When the pin shaft 68 is inserted into the pin shaft hole 52 by a set distance, the second sensor 65 receives a signal to instruct the linear driving member 62 to stop the driving pin shaft 68 from extending; wherein, the set distance means: when the pin 68 is inserted and positioned, the set pin 68 needs to be inserted into the pin hole 52. When the pin 68 returns into the positioning boss 69 (i.e., the end of the pin 68 does not extend beyond the positioning boss 69), the third sensor 66 receives a signal to instruct the linear drive 62 to stop driving the pin 68 to retract.
Further, the pin 68 is fixedly connected with a sensing element 67, and the sensing element 67 extends out of the positioning seat 610 and moves axially synchronously with the pin 68, i.e. the sensing element 67 is fixed on the pin 68 and can move relative to the positioning seat 610; the second sensor 65 and the third sensor 66 are both arranged above the sensing piece 67, and the second sensor 65 and the third sensor 66 determine the position state of the pin 68 through the position of the sensing piece 67.
When the sensing piece 67 moves to correspond to the second sensor 65, the second sensor 65 receives a signal that the pin 68 completes plugging and positioning, and the linear driving piece 62 stops driving;
when the sensing piece 67 moves to correspond to the third sensor 66, the third sensor 66 receives a signal that the second end of the pin 68 returns to the positioning boss 69, and the linear driving piece 62 stops driving;
The positioning device further includes a controller to which signals received by the second sensor 65 and the third sensor 66 are transmitted, and which transmits a signal to stop driving to the linear driving member 62. The signal received by the first sensor 63 is also transmitted to the controller, which sends a signal to the linear actuator 62 that the drive pin 68 is extended. The telescopic driving piece 11, the linear driving piece 62, the sensor assembly and the controller are matched, the process that the automatic driving pin shaft 68 is positioned or independent of the pin shaft hole 52 is achieved, the operation is simple and convenient, the automation degree is high, and the labor and time cost are saved. The controller may be a PLC controller or a microprocessor.
When the positioning device is not provided with the sensor assembly or the controller, the positioning state of the positioning boss 69 and the positioning groove 53 can be monitored manually, and the linear driving member 62 and the telescopic driving member 11 can be operated manually, so that the cost of the positioning device can be reduced. The sensor assembly and the controller can be selected according to the needs.
Further, the first sensor 63, the second sensor 65 and the third sensor 66 are proximity switches, and are positioned in a non-contact manner so as to adjust the motion of the linear driving member 62 or the swing motion of the latch assembly.
Further, the sensor assembly further includes a fixing frame 64, the fixing frame 64 is fixed to the positioning seat 610, and the first sensor 63, the second sensor 65 and the third sensor 66 are all fixed to the fixing frame 64. The fixing frame 64 includes a first bracket and a second bracket, the first bracket extends towards the direction of the latch seat 54, the first sensor 63 is fixed on the first bracket, the second bracket is arranged above the sensing piece 67, the second sensor 65 and the third sensor 66 are both arranged on the second bracket, and the probe positions of the second sensor 65 and the third sensor 66 are level, so that the two sensors can determine the position state of the pin 68 through the same sensing piece 67.
Further, as shown in fig. 8 and 9, the fixing frame 64 is formed on the positioning seat 610, the positioning seat 610 is connected to the supporting bottom plate 611, the housing of the linear driving member 62 is fixed on the supporting bottom plate 611, and the fixing frame 64, the positioning seat 610 and the supporting bottom plate 611 form an integrated supporting structure, so that the parts of the pin shaft assembly 6 are simplified, the transportation and the installation are convenient, and the axial positioning accuracy is guaranteed.
In another embodiment, the pin assembly 6 further comprises a first support 61, the first support 61 is used for connecting a second support beam or a third support beam, the latch seat assembly 5 further comprises a second support 51, the second support 51 is used for connecting the first support beam 4, and the lifting beam 7 drives the positioning boss 69 to swing into the positioning groove 53.
In addition, the pin shaft assembly 6 is arranged on the first supporting beam 4, the pin seat assembly 5 is arranged on the second supporting beam and the third supporting beam, and the working principle is the same as that of the above mode.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
