Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment and relates to a wrench silo. Background Art

[0002] Wrenches are commonly used tools for disassembling and assembling bolts and nuts. Wrenches generally need to be produced through machining. During the process of automated production, processing and assembly, wrench-type workpieces need to be pre-positioned in an angular direction and stored and fed to facilitate subsequent processing and assembly.

[0003] For this reason, a wrench silo for storing and transporting wrenches is often provided in the processing equipment of wrenches. For example, a wrench opening automatic processing device disclosed in Chinese patent literature [Announcement No. CN212976405U] includes a storage silo and a pushing mechanism. The storage silo is located on the top of the workbench, and a number of wrenches are placed horizontally into the storage silo from the top of the storage silo in sequence. A discharge port is provided at the bottom of the storage silo facing the side of the stamping table, and the wrench located at the bottom of the storage silo is pushed out of the storage silo by the pushing mechanism. The pushing mechanism includes a pushing linear drive mechanism and a pushing seat. The pushing linear drive mechanism is fixedly arranged on the top of the workbench, located on one side of the storage silo. The pushing seat is fixedly arranged at the end of the piston rod of the pushing linear drive mechanism, which is compatible with the wrench, and the wrench is pushed out of the storage silo by the pushing linear drive mechanism. The above-mentioned storage bin and pushing mechanism can only stack and store the wrenches in a flat position and push them out horizontally, but cannot adjust the wrenches to be placed vertically on their sides, resulting in failure to meet the machining requirements when the wrenches are positioned on their sides. Summary of the invention

[0004] The utility model aims to solve the above problems in the prior art and proposes a wrench silo, which solves the technical problem of how to enable the wrench to be positioned and placed sideways.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A wrench silo comprises a workbench, on which is provided a storage rack for stacking wrenches in a flat position, and is characterized in that the workbench is also provided with a flip rack corresponding to the storage rack, and a positioning groove for inserting the wrench is provided on the side of the flip rack facing the storage rack, and a material taking notch is provided in the middle of both side walls of the positioning groove, and a feeding mechanism for conveying the wrenches in a flat position from the storage rack to the positioning groove of the flip rack is provided between the flip rack and the storage rack, and a swing cylinder is connected to one end of the flip rack, and the swing cylinder can drive the flip rack to make the notch of the positioning groove face upward.

[0007] During operation, the notch of the positioning groove of the flip frame faces the storage rack, and then the feeding mechanism transports the flat wrench on the storage rack to the positioning groove of the flip frame. The wrench is inserted into the positioning groove of the flip frame while maintaining a flat posture. Then the swing cylinder rotates to drive the flip frame to rotate so that the notch of the positioning groove faces upward. At this time, the wrench in the positioning groove is in a sideways posture, and the two side walls of the positioning groove position the wrench so that the wrench will not fall over. The setting of the material taking notch enables the manipulator to take the sideways wrench out of the flip frame, and the manipulator transports the wrench in a sideways posture to the machine tool for processing. After the wrench on the flip frame is taken away, the swing cylinder rotates in the opposite direction so that the notch of the positioning groove faces the storage rack again, and the feeding mechanism transports the next wrench from the storage rack to the flip frame, and the work of positioning the wrench sideways is repeated. Therefore, this wrench silo can realize the positioning and sideways placement of the wrench.

[0008] In the above-mentioned wrench silo, a support seat is provided on the workbench at the other end of the turning frame, the positioning groove is open toward one end of the support seat, an end side cylinder is fixed on the support seat, a positioning block located between the support seat and the turning frame is fixed on the piston rod of the end side cylinder, and the positioning block has a positioning notch at one end facing the turning frame for the end of the wrench to be embedded, and the shape of the positioning notch corresponds to the shape of the end of the wrench.

[0009] The end of the wrench is a special-shaped structure, which requires direction identification. When working, after the wrench is inserted into the positioning groove, the wrench extends out of the positioning groove toward the end of the support seat, and then the piston rod of the end side cylinder extends so that the positioning notch faces the extended end of the wrench. Then the flip frame rotates. If the end position of the wrench is correct, the end of the wrench can be smoothly embedded in the positioning notch, and the flip frame can be smoothly rotated into place; if the end position of the wrench is reversed, the end of the wrench cannot enter the positioning notch, and the flip frame cannot be smoothly rotated into place, thereby preventing the reversed wrench from being grabbed by the robot for processing. After the flip frame rotates into place, the piston rod of the end side cylinder retracts, the positioning block leaves the wrench, and the robot takes out the wrench in a sideways posture.

[0010] In the above-mentioned wrench silo, a rotating shaft is fixed on the other end of the flip frame, the rotating shaft is coaxially arranged with the swing cylinder, and one end of the rotating shaft is penetrated on the support seat.

[0011] One end of the flip frame is supported and fixed on the swing cylinder, and the other end of the flip frame is supported on the support seat through a rotating shaft. The supports at both ends of the flip frame work stably, so that the positioning sideways state of the wrench is stable.

[0012] In the above-mentioned wrench silo, the storage rack includes two vertically arranged columns, and vertical grooves are respectively arranged on the opposite sides of the two columns. A guide rail is arranged on the workbench between the turning frame and the storage rack. There are two guide rails, which correspond to the two columns one by one and are inserted into the bottom of the columns. The side of the two guide rails away from each other has a baffle protruding upward.

[0013] The wrenches are stacked in a flat position in the storage rack, with the two ends of the wrenches respectively embedded in the vertical grooves of the two columns, and the bottom wrench is located on the guide rail. The feeding mechanism transports the bottom wrench along the guide rail. The guide rail has a guiding and limiting function to prevent the wrench from running off during the feeding process, so that the wrench can smoothly enter the positioning groove of the flip rack, thereby allowing the wrench to smoothly adjust its posture to sideways.

[0014] In the above-mentioned wrench silo, the feeding mechanism includes a push-pull plate located between two guide rails, and the push-pull plate is connected to a feeding cylinder, and the feeding cylinder can drive the push-pull plate to move between the storage rack and the turning rack. A lifting cylinder is also provided on the workbench, and the lifting cylinder and the turning rack are respectively located on both sides of the storage rack. The piston rod of the lifting cylinder faces the turning rack and is fixed with a lifting plate, and the lifting plate can be inserted between the two wrenches at the bottom.

[0015] During operation, the piston rod of the lifting cylinder extends, the lifting plate extends and is inserted between the two columns, and then the wrenches are stacked in a flat position in the storage rack, and the bottom wrench falls on the lifting plate. The feeding cylinder drives the push-pull plate to the bottom position of the storage rack and passes the wrench. Then the lifting plate retracts, the wrench falls, and the lifting plate extends again and is inserted between the two bottom wrenches. Then the feeding cylinder retracts to make the push-pull plate transport the bottom wrench to the positioning groove of the flip rack. The feeding cylinder extends again to drive the push-pull plate to the bottom position of the storage rack and pass the wrench. The lifting plate retracts and extends again after the wrench falls, and the process is carried out in sequence.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The wrench bin can position the wrench sideways through the flip frame, so that the wrench can be taken away by the robot for processing in a sideways posture. The positioning block can also prevent the wrongly placed wrench from being taken away by the robot for machining. BRIEF DESCRIPTION OF THE DRAWINGS
