[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0026] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.
[0027] Combination Figure 1 and Figure 2As shown, the clamping mechanism provided by the embodiment of the utility model is used to be arranged on the electrode extension robot, and the clamping mechanism includes a clamping seat 1, a clamping assembly 3 and a driving member 31, wherein the clamping seat 1 is used to connect with the electrode extension robot, specifically connected with the bottom of the electrode extension robot, and the connection method between the clamping seat 1 and the electrode extension robot is not restricted and can be designed according to actual needs. The clamping seat 1 has a clamping opening 11 that matches the shape of the part to be clamped, and the matching here means that the part to be clamped can be clamped into the part to be clamped, so as to perform positioning between the clamping seat 1 and the part to be clamped, and avoid the position of the part to be clamped from shifting during the process of clamping the part to be clamped. Among them, since the electrode extension robot cannot move in the vertical direction, the present application sets an opening on one side of the clamping opening 11 to facilitate the part to be clamped to be clamped into the clamping opening 11 from the side of the clamping opening 11.
[0028] The three clamping assemblies 3 are evenly distributed on the periphery of the clamping opening 11, and the driving member 31 is connected to any one of the clamping assemblies 3, and is used to drive the three clamping assemblies 3 to close inward or expand outward to clamp or loosen the part to be clamped in the clamping opening 11, that is, when the driving member 31 drives the three clamping assemblies 3 to close inward, the three clamping assemblies 3 can extend into the clamping opening 11 to clamp the part to be clamped. Among them, the part to be clamped can be an electrode, etc., for lengthening the electrode. It can be understood that the part to be clamped can also be other structures.
[0029] In the clamping mechanism provided by the utility model, the clamping seat 1 has a clamping opening 11 that matches the shape of the part to be clamped. When in use, the part to be clamped is inserted into the clamping opening 11 through the open end of the clamping opening 11, so as to limit the position of the clamping seat 1 through the cooperation between the clamping opening 11 and the part to be clamped, and then the three clamping components 3 are driven to approach through the driving member 31, so that the three clamping components 3 are clamped on the periphery of the part to be clamped, so as to achieve multi-point positioning of the part to be clamped, thereby ensuring the clamping effect of the part to be clamped, increasing the positioning accuracy of the clamping seat 1 and the electrode extension robot, and ensuring the extension effect of the electrode.
[0030] In some embodiments, in combination Figure 1 and Figure 2 As shown, the three clamping components 3 are divided into a first clamping component 32 and two second clamping components 33. The first clamping component 32 is connected to the driving component 31. Specifically, the first clamping component 32 is arranged at the output end of the driving component 31, and the driving component 31 is arranged to be able to drive the first clamping component 32 to move along a preset direction. Among them, the driving component 31 can be a cylinder, a hydraulic cylinder or an electric push rod, etc., which can be selected according to actual needs. Specifically, the driving component 31 includes a driving cylinder body 311 and a telescopic rod. The driving cylinder body 311 can drive the telescopic rod to move along a preset direction. The preset direction here is Figure 2 The vertical direction in .
[0031] The two second clamping parts 33 are respectively hingedly connected to the first clamping part 32 through the driving rods 312. The driving member 31 is used to drive the first clamping part 32 to extend and retract, so that the first clamping part 32 can drive the free ends of the two second clamping parts 33 to close inward or expand outward through the two driving rods 312, thereby enabling the two second clamping parts 33 to be clamped on the corresponding two sides of the part to be clamped.
[0032] Under this design, the telescopic rod can be extended or retracted by driving the cylinder body 311 to drive a first clamping component 32 and two second clamping components 33 to move inward or outward, thereby realizing that a driving member 31 drives the three clamping components 3 to move synchronously, thereby making the structure simple and saving costs while increasing the uniformity of the force applied to the electrode, achieving non-eccentric clamping of the electrode, and a relatively stable force applied to the electrode, thereby ensuring the clamping effect of the electrode, thereby further improving the work efficiency of electrode extension.
[0033] Further optimized, the first clamping part 32 is arranged on the extension line of the symmetry axis of the two second clamping parts 33. At this time, the above-mentioned preset direction is consistent with the direction of the extension line of the symmetry axis of the two second clamping parts 33. At the same time, the two second clamping parts 33 are relatively arranged on both sides of the clamping opening 11. Under this design, the first clamping part 32 can be pressed against one side of the part to be clamped, and the two second clamping parts 33 are symmetrically clamped on the corresponding two sides of the part to be clamped along the extension line of the first clamping part 32, further ensuring the uniformity of the force on the part to be clamped.
[0034] For further optimization, the first clamping part 32 and the two second clamping parts 33 are arranged at intervals along the circumferential direction of the part to be clamped, that is, the deflection angle between two adjacent second clamping parts 33 is the same as the deflection angle between the first clamping part 32 and the second clamping part 33, so that the part to be clamped is evenly stressed in its circumferential direction, ensuring the clamping effect of the part to be clamped.
[0035] Combination Figure 1 , Figure 2 and Figure 3As shown, the first clamping component 32 includes a slide 321 arranged at the output end of the driving member 31, that is, the slide 321 is arranged on the periphery of the telescopic rod of the driving member 31, so that the slide 321 can move synchronously with the telescopic rod. When in use, during the extension of the telescopic rod, the slide 321 can extend out of the clamping port 11 to act on one side of the component to be clamped. The two driving rods 312 are respectively hingedly connected to the two sides of the slide 321, and the slide 321 and the clamping seat 1 slide and retract under the action of the guide structure. Under this design method, the slide 321 can move relative to the clamping seat 1 along the above-mentioned preset direction to guide the extension of the telescopic rod, ensuring that the two driving rods 312 can be driven to move synchronously through the extension of the telescopic rod.
[0036] In some embodiments, Figure 3 As shown, the guide structure includes a slide groove 3211 arranged on the top and bottom surfaces of the slide seat 321 and a slider 12 arranged on the clamping seat 1 and matching the slide groove 3211. Under this design, the sliding cooperation between the slide seat 321 and the clamping seat 1 can be achieved through the cooperation between the slide groove 3211 and the slider 12. Specifically, a slide groove 3211 is respectively provided on the top and bottom surfaces of the slide seat 321, so that the two slide grooves 3211 are arranged on the corresponding two sides of the slide seat 321, and accordingly, a slider 12 is provided at a position of the inner side wall of the clamping seat 1 corresponding to the slide groove 3211, and the slider 12 is clamped in the slide groove 3211.
[0037] It can be understood that in other embodiments, the guide structure includes guide blocks arranged on the top and bottom surfaces of the slide 321 and guide grooves arranged on the clamping seat 1 and matching the guide blocks. Under this design, the sliding fit between the slide 321 and the clamping seat 1 can be achieved through the fit between the guide blocks and the guide grooves.
[0038] like Figure 1 As shown, the second clamping member 33 includes two clamping plates 331, which are rotatably arranged on the clamping seat 1, that is, the clamping plates 331 can rotate relative to the clamping seat 1, and both ends of the clamping plates 331 extend out of the position where the clamping plates 331 are hinged with the clamping seat 1. The clamping plates 331 have corresponding first and second ends, and the driving rod 312 is hingedly connected to the first end of the clamping plates 331. The second end of the second clamping member 33 is used to clamp or release the part to be clamped. Figure 2 Taking the direction shown as an example, the first end of the clamping plate 331 is the top end of the clamping plate 331, the second end of the clamping plate 331 is the bottom end of the clamping plate 331, and the first ends of the two clamping plates 331 are hingedly connected to the driving rod 312. The driving member 31 can drive the two clamping plates 331 to swing relative to the clamping seat 1 through the driving rod 312, so that the second ends of the two clamping plates 331 can move closer or farther away, thereby clamping or releasing the part to be clamped.
[0039] When in use, the driving member 31 can drive the first ends of the two clamps 331 to move away from or closer to each other through the driving rod 312, so that the second ends of the two clamps 331 move closer to or away from each other, thereby enabling the two clamps 331 to clamp or loosen the parts to be clamped. Specifically, the driving cylinder 311 drives the telescopic rod to extend, and the telescopic rod drives the slide 321 to move toward the direction of the parts to be clamped. At this time, in order to adapt to the change in the position of the slide 321, the positions of the driving rod 312 and the clamp 331 also change. Specifically, the slide 321 will push the end of the driving rod 312 connected to the clamp 331 to move outward, thereby enabling the driving rod 312 to push the first end of the clamp 331 to move outward. At this time, the second end of the clamp 331 will be brought inward, thereby enabling the two clamps 331 to clamp on both sides of the parts to be clamped. On the contrary, when the driving cylinder 311 drives the telescopic rod to retract, the second end of the clamping plate 331 will move outward, thereby allowing the two clamping plates 331 to release the clamped part. This driving method has a simple structure and can achieve synchronous movement of the slide seat 321 and the two clamping plates 331, thereby causing the periphery of the clamped part to be stressed simultaneously and evenly, thereby ensuring the clamping effect of the clamped part.
[0040] like Figure 2 As shown, the second clamping component 33 also includes two chucks 332, which are hingedly arranged at the second end of the clamping plate 331, and the shape of the clamping surface of the chuck 332 matches the shape of the peripheral wall of the component to be clamped. The matching here means that the clamping surface of the chuck 332 can fit on the peripheral wall of the component to be clamped, so as to increase the contact area between the chuck 332 and the component to be clamped, and ensure that the chuck 332 can stably clamp on the periphery of the component to be clamped. In addition, the chuck 332 is hingedly arranged on the clamping plate 331 so that when the clamping surface of the chuck 332 contacts the peripheral wall of the component to be clamped, the angle between itself and the clamping plate 331 can be changed according to the shape of the peripheral wall of the component to be clamped, so that the chuck 332 can fit closely on the periphery of the peripheral wall of the component to be clamped.
[0041] Further optimized, each clamping plate 331 includes two plate bodies. Specifically, a hinge shaft is provided at the end of the driving rod 312, and the hinge shaft extends in the vertical direction, and both ends of the hinge shaft extend out of the driving rod 312, and the first ends of the two plate bodies are respectively hingedly connected to the extended ends of the two hinge shafts, so that the two plate bodies are spaced apart in the vertical direction. A hinge shaft is also provided on the side of the plate body away from the part to be clamped, and the second ends of the two plate bodies are respectively hingedly connected to the two ends of the hinge shaft there. The clamping plate 331 under this design can reduce the weight of the second clamping part 33, and at the same time can provide uniform support force to the chuck 332, ensuring the support effect of the chuck 332.
[0042] like Figure 2As shown, in some embodiments, a limit block 17 is provided on the clamping plate 331, and the limit block 17 is provided on the side of the clamping head 332 facing the driving rod 312. The limit block 17 can limit the swing range of the clamping head 332, prevent the clamping surface of the clamping head 332 from rotating to an angle that deviates from the part to be clamped, and ensure that the clamping surface of the clamping head 332 can contact the part to be clamped during the movement of the clamping head 332 toward the part to be clamped.
[0043] like Figure 2 As shown, a flexible anti-skid layer is provided on one side of the plurality of clamping components 3 facing the clamping opening 11, so as to protect the clamping components 3 and the clamped parts through the flexible anti-skid layer and ensure the clamping effect at the same time.
[0044] Specifically, one end of the slide 321 that clamps the part to be clamped is provided with a first flexible anti-skid layer 3212. The first flexible anti-skid layer 3212 can ensure the tight contact between the slide 321 and the peripheral wall of the part to be clamped. Specifically, the first flexible anti-skid layer 3212 can be a rubber layer, which can also effectively avoid hard contact between the slide 321 and the peripheral wall of the part to be clamped, thereby avoiding damage to the slide 321 or the part to be clamped.
[0045] The clamping surface of the clamp 332 is provided with a second flexible anti-skid layer 3321. The second flexible anti-skid layer 3321 can ensure the tight contact between the clamp 332 and the peripheral wall of the part to be clamped. Specifically, the second flexible anti-skid layer 3321 can be a rubber layer, which can also effectively avoid hard contact between the clamp 332 and the peripheral wall of the part to be clamped, thereby avoiding damage to the clamp 332 or the part to be clamped.
[0046] like Figure 1 As shown, the clamping seat 1 includes a bottom plate 13 and a top plate 14, and a cavity for installing three clamping assemblies 3 is formed between the bottom plate 13 and the top plate 14. Specifically, the top plate 14 and the bottom plate 13 are connected by a plurality of connecting plates 16, so that the top plate 14 and the bottom plate 13 can be arranged at intervals along the vertical direction, thereby forming a cavity. Among them, a gap should be formed between the connecting plates 16 for the chuck 332 and the slide 321 to extend out, so as to avoid affecting the chuck 332 and the slide 321 to clamp the parts to be clamped. The clamping seat 1 of this design adopts a hollow design, which can reduce its own weight and facilitate the transportation and installation of the clamping seat 1, and the top plate 14 of the clamping seat 1 is used to connect with the electrode extension robot to increase the convenience of disassembly and assembly.
[0047] like Figure 4As shown, the utility model also provides an electrode extension robot, which includes a body 2 and any one of the above-mentioned clamping mechanisms arranged on the body 2, wherein the clamping mechanism includes all the technical features of the above-mentioned clamping mechanisms. Among them, the clamping mechanism is arranged at the bottom of the body 2, and the connection between the clamping mechanism and the body 2 is not restricted, such as bolt connection, clamping connection, etc., and can be designed according to actual needs.
[0048] Among them, the bottom of the body is provided with a bracket structure so that the bottom end of the body can expose the open end of the clamping port 11, so that when the body moves in the horizontal direction, the old electrode can pass through the open end of the clamping port 11 to cooperate with the clamping port 11, and then the three clamping components 3 are driven inward by the driving member 31, so that the three clamping components 3 can be clamped on the periphery of the old electrode.
