Description

Technical Field

[0001] The utility model relates to the field of automobile parts production, in particular to a half-shell steel plate unfolding material handling device and a half-shell production line. Background Art

[0002] Truck drive axle housings are divided into cast axle housings and stamped and welded axle housings according to the blank forming process. Among them, the stamped and welded axle housings are formed by welding two half-shells to form the middle section of the axle housing. The half-shells are manufactured using a stamping process, that is, pre-cut steel plates of specific shapes, and then stamped to form the steel plates into a three-dimensional shape. The transmission structure is then installed between the two half-shells and finally welded into one. Depending on the thickness of the half-shell steel plates, cold pressing and hot pressing processes can be used respectively: cold pressing is generally used for steel plates with a thickness of less than 10mm, and hot pressing is used for steel plates with a thickness of more than 10mm. The thickness of the axle housing steel plates used in the commercial vehicle field is generally 11-18mm, that is, the hot pressing process accounts for the vast majority.

[0003] The traditional method for loading and unloading heated half-shell steel plates is manual lifting. However, the heated steel plate reaches temperatures of 900°C, posing a significant safety hazard to operators. The application of industrial articulated arm robots has significantly improved production efficiency and safety.

[0004] However, traditional steel plate handling generally uses magnetic loading. However, for the special process of heating production, the steel plates will demagnetize at high temperatures, making it impossible to unload them magnetically. Therefore, on the production line, an additional handling robot is required for the unloading process. For example, the quenching production line described in patent CN115109913A uses an electromagnet robot for loading and a gripping robot for unloading. Although this production line model solves the unloading problem, it requires an additional robot, which increases equipment costs and increases the planning of the robot's rotation space, that is, the difficulty of arranging the production line plant. Utility Model Content

[0005] The utility model provides a half-shell steel plate unfolding material handling device to solve the problem that steel plate workpieces cannot be transported by magnetic suction due to demagnetization during a heating process, and that adding a manipulator increases equipment cost and difficulty in space planning.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is a half-shell steel plate unfolding material handling device, comprising a frame, the frame being provided with a clamping assembly and a magnetic assembly, the clamping assembly comprising two sets of jaws, the two sets of jaws forming a clamping plane, the magnetic assembly being arranged between the two sets of jaws, a suction plane being formed on the magnetic assembly, and the suction plane and the clamping plane being not coplanar; a manipulator joint connection structure is also provided in the middle of the frame. This solution integrates two material-retrieving structures, namely, jaw clamping and magnetic suction. The appropriate material-retrieving method can be selected by flipping the position, with magnetic suction loading and clamping unloading. A set of manipulators can complete both loading and unloading, saving equipment costs. At the same time, the space required for flipping is small, which is convenient for space layout in the factory.

[0007] Preferably, the frame is T-shaped, comprising a horizontal bar and a vertical bar. One end of the vertical bar is fixedly connected to the middle of the horizontal bar, and the other end of the vertical bar is provided with the manipulator joint connection structure. Two sets of grippers are respectively provided at the ends of the horizontal bar, and the magnetic attraction assembly is installed at the connection between the horizontal bar and the vertical bar. The frame adopts a T-shaped structure, which is lightweight and convenient for arranging and installing various components thereon.

[0008] Preferably, the magnetic attraction assembly includes a spacing bracket, the spacing bracket including a first flat plate and a second flat plate, the first flat plate and the second flat plate being connected by a plurality of vertical plates, the first flat plate being fixedly connected to the crossbar and / or longitudinal bar, and the second flat plate being mounted with a plurality of electromagnets. The spacing bracket raises the attraction plane of the electromagnet relative to the frame, thereby reducing positional interference between the magnetic attraction assembly and the clamping assembly.

[0009] Preferably, an electromagnet mounting plate is mounted on the second flat plate via a spacing screw, the electromagnet mounting plate being parallel to the second flat plate, and the electromagnet is mounted on the electromagnet mounting plate, thereby further increasing the spacing between the magnetic attraction component and the clamping component, and the spacing can be adjusted via the spacing screw.

[0010] Preferably, the clamping claw includes a fixed claw and a movable claw, the rear end of the fixed claw is fixedly mounted on the bottom surface of the frame, and the positions of the frame corresponding to the clamping claws are also provided with telescopic devices, the fixed end of the telescopic device is hinged to the frame, and the telescopic end of the telescopic device is hinged to the rear end of the movable claw, the middle part of the movable claw near the rear end is hingedly mounted on the top surface of the frame, and the movable claw is located above the fixed claw.

[0011] Preferably, the telescopic device is a telescopic cylinder. The telescopic cylinder has a certain elasticity, which can prevent the heated and softened steel plate from being compressed and deformed due to excessive holding force.

[0012] To address the aforementioned issues, the present invention further provides a second aspect of a half-shell production line, comprising a manipulator body, a distal end pivot joint of the manipulator body being equipped with the aforementioned half-shell steel plate unfolding material handling device, a manipulator joint connection structure being mounted on the distal end pivot joint, a stacking platform and a press being provided on either side of the manipulator body's periphery along a first direction, and a heating furnace being provided on one side of the manipulator body's periphery along a second direction, the first and second directions being perpendicular to each other. This production line utilizes the aforementioned handling device as an actuator, switching the loading and unloading mode by rotating the distal end joint of the manipulator. Loading and unloading the heating furnace requires only one set of manipulators, optimizing the production line's spatial layout and reducing equipment costs.

[0013] Preferably, a robot track is provided between the stacking table and the press along a first direction, and the manipulator body is movably mounted on the robot track. A loading platform and an unloading platform are also provided on either side of the heating furnace along the first direction, with the loading platform being located near the stacking table and the unloading platform being located near the press. Increasing the manipulator's range of motion and providing additional loading and unloading platforms allows for temporary storage of materials according to the production rhythm, enabling flexible adjustment of the production rhythm and optimizing the production process.

[0014] It can be seen from the above technical solutions that the advantages of the present invention are: the half-shell steel plate unfolding material handling device provided by this solution integrates two material-grabbing modes, namely magnetic suction and clamping claws, and can be applied to workpieces before and after heating. Function switching can be achieved by rotating itself. At the same time, the clamping plane and the suction plane are set at intervals, and the structural interference of the components corresponding to the two functions is small. At the same time, the overall structure is compact and the required rotation space is smaller; only one set of robotic arm equipment is required to complete the loading and unloading of heated materials, which saves equipment costs, reduces the space requirements and planning difficulty of the production line, and improves production efficiency.

[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0021] Example 1

[0022] like Figure 1 As shown, a half-shell steel plate unfolding material handling device includes a frame 1, the frame 1 is a T-shaped structure, and in the plane where the T is located, there is a Figure 1 The surface you see is the top surface. The frame 1 includes a horizontal bar and a vertical bar. One end of the vertical bar is fixedly connected to the middle of the horizontal bar. The other end of the vertical bar is provided with a manipulator joint connection structure 8. For example, Figure 1 The flange structure shown in the figure; the frame 1 is provided with a clamping component and a magnetic component:

[0023] The clamping assembly includes two groups of jaws, which are respectively located at the two ends of the cross bar, and each group of jaws includes a fixed jaw 4 and a movable jaw 5 and a telescopic device. The rear end of the fixed jaw 4 is fixedly mounted on the bottom surface of the frame 1, and the movable jaw 5 is hinged to the top surface of the cross bar and is located above the fixed jaw 4. The telescopic device is used to drive the movable jaw 5 to swing. In this embodiment, the telescopic device adopts a telescopic cylinder 6. The cylinder body of the telescopic cylinder 6 is hinged on the cross bar, and the cylinder rod is hinged at the rear end of the movable jaw 5. The middle section of the movable jaw 5 is hinged to the cross bar near the rear end. Then, when the telescopic cylinder 6 is extended, the rear end of the movable jaw is lifted up and the front end is pressed down, thereby cooperating with the fixed jaw 4 to clamp the workpiece. Furthermore, the front end of the movable jaw 5 has a bending portion bent toward the fixed jaw. It can be seen from the above structure that the two jaws are parallel to each other, thereby defining a clamping plane. When the clamping assembly clamps the workpiece, the workpiece is located in the clamping plane.

[0024] The magnetic attraction assembly includes a spacing bracket 2 and a plurality of electromagnets 3. The spacing bracket 2 includes a first flat plate and a second flat plate. The first flat plate and the second flat plate are connected by a plurality of vertical plates. The first flat plate and the second flat plate are parallel to each other. The vertical plates are vertically crossed and fixedly connected to the first flat plate and the second flat plate. It can be seen that the width of the vertical plates is the distance between the first flat plate and the second flat plate. The first flat plate is fixedly connected to the top surface of the connection between the cross bar and the longitudinal bar in the frame 1. A plurality of spacing screws are installed on the second flat plate, and an electromagnet mounting plate 7 is installed through the spacing screws. Specifically, through holes are opened on the electromagnet mounting plate 7 at positions corresponding to the plurality of spacing screws, and the spacing screws Pass through the corresponding through holes and install two positioning nuts. The two positioning nuts cooperate with the upper and lower surfaces of the clamping electromagnet mounting plate 7 to fix it. The other end of the spacing screw can be fixed to the second flat plate or adopt the same positioning nut installation method. Then, the distance between the electromagnet mounting plate and the frame can be adjusted by the spacing screw. Multiple electromagnets 3 are installed on the electromagnet mounting plate 7. The preferred arrangement is symmetrical with the vertical rod. It can be seen from the above structure that multiple electromagnets 3 form a suction plane, and the suction plane is arranged parallel to the clamping plane. When the electromagnet absorbs the workpiece, the workpiece is located in the suction plane, and the electromagnetic force of the electromagnet is not less than 2000N.

[0025] Example 2

[0026] like Figure 2 As shown, this embodiment further provides a half-shell production line, including a manipulator body 9. The manipulator body 9 can adopt a multi-joint industrial robot. This is a prior art and will not be described in detail here. The end translation joint of the manipulator body 9 is installed with the half-shell steel plate unfolding material handling device described in Example 1. The manipulator joint connection structure 8 is connected to the end translation joint. The periphery of the manipulator body 9 is along the first direction (i.e. Figure 2 A stacking platform 10 and a press 12 are respectively provided on both sides of the horizontal direction of the manipulator body 9, and the outer periphery of the manipulator body 9 is along the second direction (i.e. Figure 2 A heating furnace 11 is provided on one side of the vertical direction, and the first direction and the second direction are perpendicular to each other.

[0027] Furthermore, a robot track 13 can be set along the first direction, and the manipulator body can run along the robot track 13. At the same time, the stacking table 10 and the press 12 are set at both ends of the robot track, the heating furnace is set on one side of the robot track, and the loading table 14 and the unloading table 15 are set on both sides of the heating furnace 11 along the first direction. The loading table 14 is set close to the stacking table 10, and the unloading table 15 is set close to the press 12. In this way, the temporary storage and turnover of workpieces on the loading table 14 and the unloading table 15 can be realized, and the production rhythm can be flexibly adjusted.

[0028] The working process of this embodiment is:

[0029] Heating and loading:

[0030] S1. The end joint of the manipulator body 9 rotates a certain angle so that the suction plane is horizontally facing downward. The manipulator body 9 drives the half-shell steel plate unfolding material handling device to move above the stacking table 10, and the magnetic suction component absorbs the half-shell steel plate unfolding material;

[0031] S2. The manipulator body drives the half-shell steel plate expansion material handling device to move, and the half-shell steel plate expansion material is placed into the heating furnace 11;

[0032] In S1-S2, the robot body 9 is located Figure 2 At the position shown, i.e., the left side of the robot track 13 shown in the figure, the half-shell steel plate unfolded material handling device can be used to temporarily store the half-shell steel plate unfolded material on the loading platform 14 as needed;

[0033] Stamping loading:

[0034] S3. The manipulator body 9 moves along the robot track 13 to the right position, the end joint of the manipulator body rotates a certain angle so that the suction plane is horizontally facing upward, and the manipulator body drives the half-shell steel plate unfolding material handling device to move to the heating furnace 11, and two sets of grippers grab the heated half-shell steel plate unfolded material;

[0035] S4. The robot body drives the half-shell steel plate unfolding material handling device to deliver the heated half-shell steel plate unfolding material to the press 12.

[0036] In steps S3-S4, the robot body can move the heated half-shell steel plate unfolded material from the heating zone to the unloading platform 15 for temporary storage as needed.

[0037] It can be seen from the above embodiments that the beneficial effect of the present invention is that the half-shell steel plate unfolding material handling device provided by this scheme integrates two material picking modes of magnetic suction and clamping claws, which can be applied to workpieces before and after heating. Function switching can be achieved by rotating itself. At the same time, the clamping plane and the suction plane are set at intervals, and the structural interference of the components corresponding to the two functions is small. At the same time, the overall structure is compact and the required rotation space is smaller. Only one set of robotic arm equipment is needed to complete the loading and unloading of heated materials, which saves equipment costs, reduces the space requirements and planning difficulty of the production line, and improves production efficiency.

[0038] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
