Description

Technical Field

[0001] The utility model relates to the technical field of industrial robot accessory parts, in particular to a robot base. Background Art

[0002] A Chinese patent with announcement number CN220093488U discloses a base for a dexterous welding robot, the base comprising a support plate, a plurality of permanent magnetic suction cups are fixed circumferentially at intervals on the lower end surface of the support plate, a conversion chamber is provided inside the permanent magnetic suction cup, a first permanent magnet and a second permanent magnet with opposite magnetic poles are fixed in parallel on the top of the conversion chamber, a rotating rod is rotatably connected in the conversion chamber, a pair of third permanent magnets with the same magnetic poles are fixed on the rotating rod, a conversion handle connected to the rotating rod is provided on the side of the permanent magnetic suction cup, and the permanent magnetic suction cup can be controlled to switch between a loaded or unloaded state by rotating the conversion handle to change the magnetic pole direction of the third permanent magnet.

[0003] When installing the above-mentioned base, it is necessary to place the support plate on an iron platform, and then adjust the conversion handles one by one until all the permanent magnetic suction cups are in a loaded state. After completion, it is necessary to check whether each permanent magnetic suction cup is loaded. If multiple dexterous welding robots need to be installed on an assembly line, multiple above-mentioned bases must be installed, but the permanent magnetic suction cups are arranged under the support plate in a visual blind spot. People can only observe the state of the conversion handle from the side of the above-mentioned base after squatting, and the orientation of each permanent magnetic suction cup is inconsistent. The conversion handle is located on the side of the permanent magnetic suction cup. Therefore, people need to walk around the support plate, and when they walk to any conversion handle position, they need to squat to operate or check the conversion handle. Each of the above-mentioned bases needs to repeat the above-mentioned process many times during installation, which makes the installation inconvenient. Therefore, there is still room for improvement in the above-mentioned dexterous welding robot base. Utility Model Content

[0004] In view of the disadvantage that during the installation process of the existing dexterous welding robot base, people need to repeatedly walk around the support plate while operating and checking, which makes the installation of the base inconvenient. The purpose of the utility model is to provide a robot base that is convenient for people to operate and check during installation.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A robot base comprises a supporting component and a plurality of magnetic positioning parts, wherein the magnetic positioning parts comprise a permanent magnetic suction cup fixedly connected to the supporting component and an adjusting part for adjusting the magnetic force of the permanent magnetic suction cup to be opened or closed, the permanent magnetic suction cups are arranged at intervals around the supporting component circumferentially and extend to the outside of the supporting component, the adjusting part is arranged on the top of the permanent magnetic suction cup, the adjusting part comprises a rotating rod vertically penetrated through the permanent magnetic suction cup and partially extended from the top of the permanent magnetic suction cup, and a handle part is fixedly arranged on the rotating rod.

[0007] By adopting the above scheme, the robot base of this scheme does not need to be operated or checked while walking around the base during installation. When operating the adjustment component, one can just reach out and grasp the handle component of any permanent magnetic suction cup on the base near one of the permanent magnetic suction cups. When checking the base, people can intuitively see the status of the adjustment component. Therefore, the structure of the robot base in this scheme effectively improves the convenience during installation and reduces the probability of errors when installing the base. Specifically, it reduces the need for the existing base to walk around the base while operating or checking the permanent magnetic suction cup, which may cause omissions.

[0008] Preferably, the handle component includes a handle seat, and the handle seat is provided with a labor-saving component for assisting the handle seat to rotate.

[0009] Preferably, the labor-saving component comprises an extension rod provided on the handle seat.

[0010] When adopting the above solution, a certain magnetic force needs to be overcome when turning the handle seat. The extension rod in this solution uses the lever principle to achieve the effect of saving effort.

[0011] Preferably, the extension rod is detachably connected to the handle seat.

[0012] Preferably, a threaded connection section is protruding from one end of the extension rod, and a threaded hole for threaded engagement with the threaded section is provided on the handle seat.

[0013] With the above solution, the space occupied by the base will become larger after the extension rod is installed, and people can decide whether to install the extension rod according to the actual installation position.

[0014] Preferably, a connecting piece is protruding from one end of the extension rod, and a mounting hole for inserting the connecting piece is opened on the handle seat. A limiting structure is provided between the handle seat and the extension rod, which can limit the extension rod from detaching from the handle seat by rotating the extension rod less than one circle after the extension rod is plugged into the handle seat.

[0015] Preferably, the limiting structure includes a protrusion radially protruding from the end of the connecting member along the connecting member, a guide groove opened on the inner wall of the mounting hole for guiding the sliding insertion of the protrusion, and an annular groove concentrically opened at the bottom of the mounting hole and capable of accommodating the protrusion to slide into the guide groove. When the protrusion is located in the annular groove, the extension rod can be rotated to drive the protrusion to move in the annular groove to align with the guide groove or to be misaligned with the guide groove.

[0016] By adopting the above scheme, when installing the extension rod, align the protrusion with the guide groove and insert it into the mounting hole until the bottom. At this time, the protrusion has entered the annular groove from the guide groove. By rotating the extension rod, the protrusion and the guide groove can be misaligned, so that the protrusion is confined in the annular groove and cannot escape. When the extension rod needs to be removed, the extension rod is rotated to align the protrusion with the guide groove and can be removed. Compared with the above scheme, the disassembly and installation of the extension rod in this scheme is very convenient. The main function of the extension rod is to exert a lever effect on the handle seat. After connection, it does not need to be completely fixed on the handle seat. Therefore, the extension rod can be quickly installed or disassembled to better adapt to the usage scenario.

[0017] Preferably, the connecting member and the mounting hole are tightly matched.

[0018] Preferably, the connecting piece or the protrusion is made of a magnet, and a metal that can be attracted by the magnet is embedded in the inner wall or the bottom of the mounting hole.

[0019] By adopting the above scheme and the above structure, the damping of the extension rod when rotating can be increased, and the extension rod is not easily aligned with the guide groove due to touching and rotating, resulting in separation, thereby increasing the reliability of the limit.

[0020] Preferably, the supporting component is made of stainless steel.

[0021] By adopting the above scheme, the magnetic permeability of the stainless steel material is low, and it is not easy to disperse the magnetic force of the permanent magnetic chuck, so that the adsorption performance of the permanent magnetic chuck is better.

[0022] Due to the adoption of the above technical scheme, the utility model has significant technical effects: the robot base of the scheme does not need to be operated or checked while walking around the base during installation; when operating the adjustment component, one can grasp the handle component of any permanent magnetic suction cup on the base by reaching out near one of the permanent magnetic suction cups; when checking the base, people can intuitively see the status of the adjustment component; therefore, the structure of the robot base in the scheme effectively improves the convenience during installation, and can also reduce the probability of errors when installing the base. Specifically, it reduces the need for the existing base to walk around the base while operating or checking the permanent magnetic suction cup, which may result in omissions.

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Example 1

[0034] A robot base, according to Figure 1 As shown, it includes a support component 1 for placing and positioning the robot, and a plurality of positioning holes 102 are arranged on the support component 1. The chassis of the robot is placed on the support component 1 and aligned with the positioning holes 102 and then fastened with bolts to achieve installation. A plurality of magnetic positioning parts are arranged at the bottom of the support component 1, and the magnetic positioning part includes a permanent magnetic suction cup 2 fixedly connected to the support component 1, and an adjustment part for adjusting the magnetic force of the permanent magnetic suction cup 2 to open or close is arranged on the permanent magnetic suction cup 2. The above is the prior art.

[0035] The improvement of this embodiment is that the permanent magnetic chuck 2 is arranged around the support component 1 in a circumferential direction and extends to the outside of the support component 1. Figure 1 As shown, in this embodiment, three groups of magnetic positioning parts are provided, and three pairs of wing plates 101 are convexly provided on the outer wall of the supporting part 1 at intervals, and a permanent magnetic chuck 2 is fixed between each pair of wing plates 101, and the adjusting part is arranged on the top of the permanent magnetic chuck 2. Figure 2 , 3As shown, the adjusting component includes a rotating rod 3 which is vertically penetrated through the permanent magnetic suction cup 2 and partially extends from the top of the permanent magnetic suction cup 2. A fixed magnet and a movable magnet are arranged inside the permanent magnetic suction cup 2 (the arrangement of the magnets is the prior art, and specific reference may be made to the description of the comparative documents in the background technology, which is not shown in the drawings of the specification). The movable magnet is fixed on the rotating rod 3, and the rotation of the rotating rod 3 is utilized to change the magnetic pole orientation of the movable magnet. A handle seat 4 is fixedly arranged on the rotating rod 3.

[0036] Combined with the above structure, reference Figures 1 to 3 It can be seen that the robot base in this embodiment does not need to be operated or checked while walking around the base during installation. When operating the adjustment component, you only need to reach out and grasp the handle component of any permanent magnetic suction cup 2 on the base when you are close to one of the permanent magnetic suction cups 2. When checking the base, people can intuitively see the status of the adjustment component. Therefore, the structure of the robot base in this solution effectively improves the convenience during installation and reduces the probability of errors when installing the base. Specifically, it reduces the need for the existing base to walk around the base while operating or checking the permanent magnetic suction cup 2, which may cause omissions.

[0037] Example 2

[0038] Based on the first embodiment, this embodiment further defines a robot base, wherein a labor-saving component that assists the rotation of the handle base 4 is provided on the handle base 4. Figure 4 As shown, the labor-saving component includes an extension rod 5 arranged on the handle base 4, and the extension rod 5 is detachably connected to the handle base 4. In this embodiment, a threaded connection section 7 is protruded from one end of the extension rod 5, and a threaded hole 8 for threaded engagement of the threaded section is opened on the handle base 4.

[0039] In combination with the above structure, a certain magnetic force needs to be overcome when rotating the handle seat 4. The extension rod 5 in this solution uses the lever principle to achieve the effect of saving effort. Since the space occupied by the base will become larger after the extension rod 5 is installed, people can decide whether to install the extension rod 5 based on the space size of the site during actual installation.

[0040] Example 3

[0041] Based on Example 2, this example further defines a robot base. Figure 5 , 6 As shown, a connecting piece 6 is protruded at one end of the extension rod 5, a mounting hole 9 for inserting the connecting piece 6 is provided on the handle seat 4, a limiting structure is provided between the handle seat 4 and the extension rod 5, the limiting structure includes a protrusion 10 protruded radially along the end of the connecting piece 6, and a guide groove 11 for guiding the protrusion 10 to slide and insert is provided on the inner wall of the mounting hole 9. Figure 7 , 8As shown, an annular groove 12 concentric with the mounting hole 9 is provided at the bottom of the mounting hole 9, and the protrusion 10 slides from the guide groove 11 into the annular groove 12. When the protrusion 10 is located in the annular groove 12, the extension rod 5 is rotated to drive the protrusion 10 to move in the annular groove 12. During this process, the protrusion 10 can be aligned with the guide groove 11 or be misaligned with the guide groove 11. In this embodiment, the connecting member 6 or the protrusion 10 is made of a magnet, and a metal that can be attracted by the magnet is embedded in the inner wall or bottom of the mounting hole 9.

[0042] Combined with the above structure, reference Figures 5 to 8 It can be known that when installing the extension rod 5 on the handle base 4, the protrusion 10 is aligned with the guide groove 11 and inserted into the mounting hole 9 until the bottom. At this time, the protrusion 10 has entered the annular groove 12 from the guide groove 11. By rotating the extension rod 5, the protrusion 10 and the guide groove 11 can be misaligned, so that the protrusion 10 is confined in the annular groove 12 and cannot be separated. When the extension rod 5 needs to be removed, the extension rod 5 is rotated to align the protrusion 10 with the guide groove 11 and can be taken out. This makes the disassembly and installation of the extension rod 5 very convenient. The main function of the extension rod 5 is to apply a lever effect to the handle base 4. After connection, it does not need to be completely fixed on the handle base 4. Therefore, the extension rod 5 can be quickly installed or disassembled to better adapt to the usage scenario.

[0043] The magnetic force of the magnet is used to increase the damping of the extension rod 5 when it rotates. The extension rod 5 is not likely to be aligned with the guide groove 11 due to contact and rotation, resulting in separation, thereby increasing the reliability of the limit.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
