Description

[Technical field]

[0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to an automatic pin pulling and locking device for a turning machine and a working method thereof. [Background technology]

[0002] The turning machine used on the production line, when there are products to be processed or assembled on the turning machine that need to be turned over, the turning mechanism of the turning machine is given a turning instruction by loosening or tightening the corresponding lock or fixing pin on the turning machine, and then the turning machine clamps the product to be processed to turn it over. At present, when the turning machine needs to turn over, a pin pulling action needs to be implemented on the turning machine to enable the turning structure on the turning machine to be able to rotate without being restricted. When the turning is completed, in order to prevent the turning machine from moving when the product is assembled, the previous pin pulling action is changed to a pin pulling action, which limits the turning structure on the turning machine, reduces the burden on the motor, and facilitates the assembly of the workers.

[0003] However, there are some problems in the use of the current flip machine. Some models of flip machines need to plug and pull out fixed pins to realize the flipping and limiting work of the flip machine. When flipping, the flip machine is driven by a motor to flip. Due to the fast work pace on the production line, the fixed pins on the flip machine are manually plugged and pulled out, and then the motor is visually controlled to drive the flip machine to rotate, and then the products on the production line are assembled back to the production line. The visual control of the flipping accuracy of the flip machine is poor, which will cause the fixed pins to fail to reset. Not only is the work cycle long, affecting the assembly and assembly efficiency, but also reducing the economic benefits of the enterprise. If the work that originally requires one person is arranged to specifically control the above-mentioned start and stop work, there will be a waste of labor. Too much manpower on the production line is not in line with the original intention of modern industrial automation. Moreover, once the work cycle on the production line is prolonged, it will affect the assembly progress of subsequent products. Therefore, in response to the above problems, this solution provides a device that can automatically pull out and plug in pins of the flip machine.

[0004] The disclosure of the above background technology content is only used to assist in understanding the inventive concept and technical solution of the present invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. [Summary of the invention]

[0005] The purpose of the present invention is to provide an automatic pin pulling and locking device for a turning machine and a working method thereof, so as to solve the problems of poor working accuracy of the turning machine driven by visual inspection in existing work, inability to reset the fixing pin, long working cycle, affecting efficiency, waste of labor and affecting the progress of subsequent assembly.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] Furthermore, a guide rail is provided on the fixed plate, and the connecting arm is sleeved on the guide rail of the fixed plate through a guide groove at the bottom of its own guide seat.

[0010] Furthermore, a U-shaped through notch is provided on the top and front end surface of the claw.

[0011] Furthermore, windows are provided at the front and rear ends of the viewing box, circular through holes are provided at the left and right sides of the viewing box, and the rotating shaft is arranged in the circular through hole at the right end face of the viewing box.

[0012] Furthermore, a motor and a control system are arranged in the control box, and a transmission shaft of the motor passes through a circular through hole on the left side of the viewing box and is connected to the left side of the coupling.

[0013] Furthermore, a fixing strip is provided on the right side of the visual box, and two sensor holes are provided on the right side of the front end surface of the fixing strip, and a sensor is respectively provided in the two sensor holes.

[0014] Furthermore, a guide rail groove is provided at the bottom of the travel base, and a travel guide rail is provided in the guide rail groove.

[0015] A working method of an automatic pin pulling and locking device for a turning machine comprises the following steps:

[0016] Step 1: Through electric drive, the travel base moves on the travel guide rail toward the turning machine on the production line. The travel base drives the pin pulling assembly and the rotating assembly to move. The claw of the pin pulling assembly contacts the fixed pin on the turning machine, and the hexagon socket sleeve on the rotating assembly fits the rotating shaft of the turning machine, preparing for the next action.

[0017] Step 2: The control system gives a command to the cylinder, the cylinder lifts the connecting arm and moves backward, the claw on the connecting arm drives the fixed pin on the flip machine to move backward, when the connecting arm moves to the bottom of the sensor on the fixed strip, the sensor detects the object, the signal is fed back to the control system, the control system controls the cylinder to stop, the fixed pin is pulled out, and the flip chuck on the flip machine can rotate;

[0018] Step 3: The motor in the control box drives the shaft to rotate according to the signal given by the control system. The hexagonal sleeve on the shaft drives the turning shaft of the turning machine to rotate. The two sensors on the fixed bar in front of the shaft sense the posture of the induction ring and the induction bump on the shaft. When the turning machine completes the rotation, the sensor on the fixed bar feeds back the signal to the control system, and the motor stops rotating.

[0019] Step 4: After the turning machine completes the rotation, the control system sends a signal to the cylinder, the cylinder's push rod is reset, and the connecting arm and the claw are reset accordingly. At the same time, the fixed pin on the turning machine is reset, completing the latching action, and the turning chuck of the turning machine is limited;

[0020] Step 5: After completing the above actions, the travel base drives the pin pulling assembly and the rotating assembly to move to the left, waiting for the next flipping action.

[0021] The beneficial effects achieved by the present invention are:

[0022] (1) The device combines the three actions of inserting, pulling out the pin and driving the flip, which can eliminate the need for manual control of first pulling out the pin, then driving the flip, and then controlling the pin. The above-mentioned actions can be completed by the device according to the set beat sequence through sensors and controllers, shortening the time required between actions; the device eliminates the need for manual operation, and can well ensure the accuracy of flipping through the judgment of the control system and sensors. The fixed pin on the flipping machine can be reset once, reducing work errors and improving work efficiency.

[0023] (2) After the device completes the established procedure, there is no need for manual control of multiple procedures, which reduces the number of operating actions and does not require additional workers to be responsible for the task, thus reducing the waste of labor. The production rhythm can run stably, ensuring that the subsequent assembly progresses steadily.

[0024] (3) During the production and assembly process, the rework time is shortened, which indirectly improves the economic benefits of the enterprise; this device is conducive to realizing production line automation and is in line with the trend of modern industrial automation.
