Description

Technical Field

[0001] This utility model relates to the field of material feeding technology for exchange worktables, and in particular to an automatic feeding exchange worktable. Background Technology

[0002] Traditional machine tools mostly adopt a single-point station design. In recent years, in order to improve processing efficiency, robotic arms have been used to realize automated loading and unloading. However, because the conveying path is long, it is difficult to use a single robotic arm to stably convey materials.

[0003] Existing exchange workbenches, such as the chain double exchange workbench disclosed in announcement number CN220480875U, have annular slides and annular chain assemblies set on a support. The annular slides are located between the support and the annular chain assembly, and a first workbench assembly and a second workbench assembly are spaced apart on the annular chain assembly. The annular chain assembly drives the first and second workbench assemblies to move simultaneously. However, it can only achieve continuous material conveying, which is difficult to synchronize with subsequent processing. It is very easy for material to accumulate on the workbench, and the single conveyor belt structure is difficult to fix each individual material, making the material prone to positional displacement during transportation and processing, which can also affect the feeding efficiency and processing quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the difficulty in smoothly conveying materials on a workbench in the prior art, and to propose an automatic feeding exchange workbench.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic feeding exchange workbench includes a body, on which feeding mechanisms for loading and unloading are symmetrically arranged on the left and right sides. A stepping transfer platform is rotatably arranged in the middle of the body between the two feeding mechanisms. Two transfer mechanisms for receiving materials are symmetrically arranged on the stepping transfer platform. A robotic arm for moving materials between the two feeding mechanisms and the transfer mechanism is arranged at the rear of the body.

[0007] Preferably, the feeding mechanism includes a load-bearing bracket integrally connected to the machine body. A guide elongated hole is provided at the top of the load-bearing bracket. A mobile carrier for placing materials is slidably fitted in the guide elongated hole. A traction turntable is rotatably mounted on the load-bearing bracket. A traction swing rod, which is movably pulled by the traction turntable and used to move the mobile carrier, is mounted on the machine body via a pin.

[0008] Preferably, the guide hole is inclined downward toward the stepping transfer table.

[0009] Preferably, an eccentrically positioned active traction bolt is integrally connected to the traction turntable, a drive elongated hole for slidingly fitting the active traction bolt is opened at the middle end of the traction swing arm, a driven elongated hole is opened at the upper end of the traction swing arm, and a driven traction bolt that is slidably fitted into the driven elongated hole is integrally connected to the moving vehicle.

[0010] Preferably, the transfer mechanism includes a load-bearing column integrally connected to the stepping transfer platform, a load-bearing plate integrally connected to the load-bearing column, a ball screw rotatably installed in the load-bearing column, a lifting nut provided on the ball screw, a tensioning rod movably pulled by the lifting nut installed on the lower end pin of the load-bearing plate, a lifting rod movably pulled by the tensioning rod slidably installed in the load-bearing plate, and a load-bearing plate for vertically placing materials fixedly installed on the lifting rod;

[0011] The transfer mechanism also includes a reciprocating gear keyed to a ball screw, a driven rack slidably mounted on the load-bearing column and meshing with the reciprocating gear, and a limiting clamp for clamping materials integrally connected to the driven rack.

[0012] Preferably, the load-bearing plate and the lifting rod are horizontally connected through the top of the load-bearing plate.

[0013] Preferably, a traction rod is pin-connected between the lifting nut and the lower end of the tensioning rod, the tensioning rod has a traction elongated hole, and a traction yoke is integrally connected to the lifting rod and slidably fitted into the traction elongated hole.

[0014] Preferably, there are two driven racks, which are symmetrically arranged on both sides of the reciprocating gear.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This utility model provides a feeding mechanism on the left and right sides of the machine body and uses a load-bearing bracket with an inclined guide hole to facilitate the installation of a moving carrier that tilts towards the center of the machine body. The moving carrier can reciprocate according to the loading and unloading needs by driving the traction swing arm through the traction turntable.

[0017] 2. This utility model utilizes a stepping transfer table to set up two sets of transfer mechanisms. By setting a ball screw between the load-bearing column and the load-bearing plate, and by setting a lifting nut and a reciprocating gear driven by the ball screw, the load-bearing plate used to support the material can be vertically lifted and lowered. At the same time, the material on the load-bearing plate is clamped and fixed by the opposing moving limit clamps. Attached Figure Description

[0027] 5. Robotic arm. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-4 An automatic feeding exchange workbench includes a body 1, with feeding mechanisms 2 for loading and unloading materials symmetrically arranged on the left and right sides of the body 1. See the attached instruction manual for details. Figure 1 With appendix Figure 2The feeding mechanism 2 includes a load-bearing bracket 21 integrally connected to the machine body 1. A guide elongated hole 22 is provided at the top of the load-bearing bracket 21. A movable carrier 23 for placing materials is slidably fitted in the guide elongated hole 22. A traction turntable 24 is rotatably mounted on the load-bearing bracket 21. A traction swing rod 25, which is movably pulled by the traction turntable 24 and used to move the movable carrier 23, is mounted on the machine body 1 by a pin. It should be noted that by setting load-bearing brackets 21 symmetrical about the stepping transfer table 3 on the left and right sides of the machine body 1, the periodically deflecting traction swing rod 25 drives the movable carrier 23 to move along the guide elongated hole 22, so as to facilitate the transfer of materials between the feeding mechanism 2 and the transfer mechanism 4.

[0030] A stepper transfer table 3 is rotatably mounted in the middle of the machine body 1, located between two sets of feeding mechanisms 2. A stepper motor is mounted on the machine body 1 to drive the stepper transfer table 3 to perform step-by-step rotational motion, so that the stepper transfer table 3 deflects 90° each time.

[0031] Two sets of transfer mechanisms 4 for receiving materials are symmetrically arranged on the stepping transfer table 3. The transfer mechanism 4 includes a load-bearing column 41 integrally connected to the stepping transfer table 3, a load-bearing plate 42 integrally connected to the load-bearing column 41, a ball screw 43 rotatably installed in the load-bearing column 41, a lifting nut 44 provided on the ball screw 43, a tensioning rod 45 movably pulled by the lifting nut 44 is installed on the lower end of the load-bearing plate 42, a lifting rod 46 movably pulled by the tensioning rod 45 is slidably installed in the load-bearing plate 42, and a load-bearing plate 47 for vertically placing materials is fixedly installed on the lifting rod 46. It should be noted that the load-bearing plate 42 has a groove, and the load-bearing plate 47 is slidably fitted into the groove. By driving the height position of the load-bearing plate 47, the material can be initially fitted into the load-bearing plate 42 at different depths.

[0032] The transfer mechanism 4 also includes a reciprocating gear 49 keyed to the ball screw 43, a driven rack 410 slidably mounted on the load column 41 and meshing with the reciprocating gear 49, and a limiting clamping plate 411 for clamping materials integrally connected to the driven rack 410. By driving the two limiting clamping plates 411 to move towards each other, the material located on the load plate 47 is symmetrically clamped and limited.

[0033] A robotic arm 5 is installed at the rear of the machine body 1 to move materials between the two sets of feeding mechanisms 2 and transfer mechanisms 4. It should be noted that the robotic arm 5 grasps the materials to adjust their position between the feeding mechanism 2 and the transfer mechanism 4.

[0034] The guide hole 22 is inclined downwards towards the stepping transfer table 3 to facilitate highly differentiated adjustment of the material. It is worth noting that because the material is a magnetic metal part, and the load plate 47 also has opposite magnetic poles that attract the metal part, the material can be stably adsorbed on the load plate 47.

[0035] Please refer to the instruction manual for details. Figure 2 An eccentrically positioned active traction bolt 241 is integrally connected to the traction turntable 24. A drive elongated hole 251 for slidingly fitting the active traction bolt 241 is opened at the middle end of the traction swing arm 25. A driven elongated hole 252 is opened at the upper end of the traction swing arm 25. A driven traction bolt 231 that is slidably fitted into the driven elongated hole 252 is integrally connected to the moving vehicle 23, thereby converting the circular motion of the traction turntable 24 into the reciprocating linear motion of the moving vehicle 23.

[0036] The load-bearing plate 47 and the lifting rod 46 are horizontally connected through the top of the load-bearing plate 42.

[0037] A traction rod 48 is pin-connected between the lower end of the lifting nut 44 and the tension rod 45. The tension rod 45 has a traction elongated hole 451. A traction yoke 461 is integrally connected to the lifting rod 46 and is slidably fitted into the traction elongated hole 451. It should be noted that a guide block is integrally connected to the lifting nut 44 and slidably installed on the load-bearing column 41, so that the lifting nut 44 moves linearly with the ball screw 43.

[0038] There are two driven racks 410, which are symmetrically arranged on both sides of the reciprocating gear 49.

[0039] It should be noted that the specific model and specifications of the robotic arm 5 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0040] The functional principle of this utility model can be explained through the following operation methods:

[0041] The operation of a set of feeding mechanisms 2 on the left side is controlled. The rotating traction turntable 24 drives the traction swing arm 25 to deflect, so that the moving carrier 23 moves along the guide hole 22 toward the stepping transfer table 3.

[0042] The robotic arm 5 moves the materials on the mobile carrier 23 to a nearby set of transfer mechanisms 4;

[0043] Control the rotation of the ball screw 43, the lifting nut 44 moves down, and the tension rod 45 is pulled by the traction rod 48. The tension rod 45 pulls the lifting rod 46 to move vertically down. The material moves down by supporting the load plate 47. The ball screw 43 drives the reciprocating gear 49 to rotate, so that the two driven racks 410 move towards each other. The limiting clamp 411 clamps and limits the material on the load plate 47.

[0044] Then control the operation of another set of feeding mechanisms 2 on the right side. The rotating traction turntable 24 drives the traction swing arm 25 to deflect, so that the moving carrier 23 moves along the guide hole 22 toward the stepping transfer table 3.

[0045] The control robot 5 moves the material on the load plate 47 to the feeding mechanism 2 on the right side.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
