Technical Field

[0001] This utility model relates to an automatic correction and clamping mechanism for cylindrical structural parts, belonging to the technical field of turnover grippers. Background Technology

[0002] Currently, there are various types of solid and hollow cylindrical structural components. During industrial production, there is a need for frequent automated turnover. The turnover needs can be met by radially clamping the cylindrical structural components.

[0003] Traditional turnover fixtures use relative clamping jaws, and the opening and closing displacement between the two jaws is achieved by a drive source such as a cylinder to meet the clamping requirements of cylindrical structural parts. However, cylindrical structural parts have many different diameters, and it is difficult to program and control the jaw stroke precisely, which can easily cause clamping damage to the outer surface.

[0004] Considering the clamping force and versatility design, an elastic floating structure will be designed on the relative opening and closing surfaces of the jaws. Floating clamping is achieved through the floating displacement of the jaws. On the one hand, it meets the floating clamping adaptation of products of different specifications, and on the other hand, it is not easy to cause surface damage.

[0005] In automated turnover processes, the positioning accuracy of the cylindrical structural components is required to be high. Traditional floating structures have difficulty meeting the requirements for axis centering accuracy, especially in achieving reliable synchronous drive and stable floating coordination. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of the prior art and to propose an automatic correction and clamping mechanism for cylindrical structural components, which addresses the problems of insufficient centering accuracy due to the difficulty in synchronous driving of floating fixtures and the difficulty in setting up floating structures.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic correction and clamping mechanism for cylindrical structural components includes a clamping base. Two clamping blocks with relative opening and closing displacements are provided on one side of the bottom surface of the clamping base. A limiting groove is provided on the clamping surface of any of the clamping blocks. The clamping base has an inlet and outlet slot located between the two clamping blocks. The fixture base is provided with a floating linkage seat that is respectively connected to the two clamping blocks and a linear drive source that is connected to the floating linkage seat. The linear displacement direction of the linear drive source is perpendicular to the opening and closing displacement direction of the two clamping blocks. A steering transmission part is provided between any clamping block and the floating linkage seat.

[0008] Preferably, the steering transmission unit includes a guide post disposed on the clamping block, an opening and closing guide groove disposed on the clamping base, and an inclined opening and closing strip groove disposed on the floating linkage seat, wherein the guide post passes through the opening and closing guide groove and the inclined opening and closing strip groove.

[0009] Preferably, the bottom surface of the clamp base is provided with a slide rail mechanism for slidably engaging the clamp block, the slide rail mechanism including two spaced apart and detachably mounted slide rail side stops on the clamp base.

[0010] Preferably, the floating linkage seat is slidably coupled to the fixture base, and a floating connection mechanism is provided between the floating linkage seat and the linear drive source.

[0011] Preferably, the floating connection mechanism includes a linkage block disposed on the linear drive source, at least one floating guide rod disposed on the floating linkage seat and passing through the linkage block, and a spring body limited between the floating linkage seat and the linkage block is sleeved on any of the floating guide rods.

[0012] Preferably, the floating linkage seat and the linear drive source are detachably mounted on the fixture base.

[0014] Preferably, the clamping surface of the limiting groove is provided with a plurality of buffer storage grooves, and a buffer protection body can be detachably installed in any of the buffer storage grooves.

[0015] The beneficial effects of this utility model are mainly reflected in: 1.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0026] This utility model provides an automatic correction and clamping mechanism for cylindrical structural components, such as... Figures 1 to 5 As shown, it includes a clamp base 1, and two clamping blocks 2 with relative opening and closing displacement are provided on one side of the bottom surface of the clamp base 1. A limiting groove 20 is provided on the clamping surface of any clamping block 2, and the clamp base 1 has an inlet and outlet slot 3 located between the two clamping blocks.

[0027] The fixture base 1 is provided with a floating linkage seat 4 that is connected to two clamping blocks 2 respectively, and a linear drive source 5 that is connected to the floating linkage seat 4 in a floating transmission manner. The linear displacement direction of the linear drive source 5 is perpendicular to the opening and closing displacement direction of the two clamping blocks. A steering transmission part 6 is provided between any clamping block and the floating linkage seat.

[0028] Detailed implementation process and principle explanation: This automatic correction clamping mechanism is used for clamping cylindrical structural parts. Traditional clamps use cylinders or similar devices to directly and rigidly drive the clamping blocks, which can cause clamping damage to the cylindrical structural parts. In addition, due to the poor linkage of the clamping blocks, the positional accuracy of the central axis of the clamped cylindrical structural parts is affected, resulting in a certain degree of offset.

[0029] In this case, the clamping blocks are initially separated, and the cylindrical structure enters the inlet / outlet slot 3. The linear drive source 5 drives the floating linkage seat 4. After the floating linkage seat 4 generates a floating displacement, it acts on the clamping block 2 through the steering transmission part 6, converting the linear displacement of the floating linkage seat 4 into the relative clamping displacement of the two clamping blocks, so that the clamping blocks have a floating clamping force. At the same time, under the linkage action of the floating linkage seat 4, the two clamping blocks have the characteristic of centering and clamping the cylindrical structure through the limiting groove 20.

[0030] In one specific embodiment, the steering transmission unit 6 includes a guide post 61 disposed on the clamping block 2, an opening and closing guide groove 62 disposed on the clamping base 1, and an inclined opening and closing strip groove 63 disposed on the floating linkage seat 4. The guide post passes through the opening and closing guide groove and the inclined opening and closing strip groove.

[0031] Specifically, the guide post 61 is linearly displaced within the opening and closing guide groove. When the floating linkage seat 4 produces linear displacement, its opening and closing guide groove will tilt and guide the guide post 61, forcing the guide post 61 to make linear displacement along the opening and closing guide groove, thus realizing the opening and closing displacement drive of the clamping block.

[0032] Of course, the steering transmission unit 6 is only one specific embodiment of this case. It can also adopt the linkage torsion arm method, that is, convert the linear displacement into the opening and closing displacement of the clamping block through the pivot swing transmission method.

[0033] In one specific embodiment, the bottom surface of the clamp base 1 is provided with a slide rail mechanism 7 for slidingly engaging the clamping block. The slide rail mechanism includes two spaced-apart slide rail side stops 70 that are detachably disposed on the clamp base.

[0034] The sliding mechanism 7 enables the sliding engagement of the clamping block, thus meeting the guiding requirements for opening and closing displacement.

[0035] In one specific embodiment, the floating linkage seat 4 is slidably coupled to the fixture base 1, and a floating connection mechanism 8 is provided between the floating linkage seat and the linear drive source.

[0036] The floating connection mechanism 8 gives the floating linkage seat 4 a linear elastic floating displacement.

[0037] In one specific embodiment, the floating connection mechanism 8 includes a linkage block 81 disposed on a linear drive source, at least one floating guide rod 82 disposed on a floating linkage seat 4 that passes through the linkage block, and a spring body 83 that is limited between the floating linkage seat and the linkage block is sleeved on any floating guide rod.

[0038] Specifically, when the linear drive source performs the extension drive operation, it drives the linkage block 81 to linear displacement. The linkage block 81 exerts pressure on the spring body 83 through the guiding movement of the floating guide rod 82. After being pressed, the spring body 83 exerts floating elastic pressure on the floating linkage seat 4. This force is transmitted to the guide post 61 through the inclined opening and closing groove 63, thereby realizing the floating clamping drive of the clamping block.

[0039] During the detachment operation, the linkage block 81 resets, which stretches the spring body 83. The spring body generates a reset pulling force on the floating linkage seat 4, which is then transmitted to the clamping block to separate and detach it.

[0040] In one specific embodiment, the floating linkage seat 4 and the linear drive source 5 are respectively detachably mounted on the fixture base.

[0041] Specifically, in order to facilitate assembly, maintenance and replacement, a detachable structure is adopted, and the floating force can be adjusted by replacing the spring body 83.

[0042] In one specific embodiment, the limiting groove is a V-shaped groove or an arc-shaped groove.

[0043] It meets the requirements of fitting with the outer peripheral wall of the cylindrical structure, achieving a centering floating contact fit.

[0044] In one specific embodiment, a plurality of buffer storage grooves 200 are provided on the clamping surface of the limiting groove, and a buffer protection body can be detachably installed in any buffer storage groove.

[0045] It can be equipped with a buffer protective body to achieve contact protection, effectively protecting the outer peripheral wall of the cylindrical structure.

[0046] As described above, this invention uses a floating linkage seat to transmit linear floating displacement, thereby driving the floating opening and closing of the clamping block. It adapts to clamping cylindrical structures with varying diameters, demonstrating strong compatibility. It meets the requirements for clamping alignment and correction, ensuring the accuracy of the clamped cylindrical components' centering position. The transmission structure design is simple and ingenious, facilitating manufacturing and widespread application. Assembly is convenient, and the floating clamping force can be adjusted by replacing the spring.

[0048] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
