Description

Technical Field

[0001] The utility model relates to the field of processing fixtures, in particular to a multi-station clamping turntable mechanism. Background Art

[0002] With the development of automation technology, multi-functional automation equipment is widely used. Products to be processed or detected are processed or detected in multiple processes in the equipment in the form of an assembly line, that is, the products are conveyed one by one to each station for processing or detection using a linear conveyor assembly line. Although the processing or detection efficiency can be improved, due to too many operation steps, the overall equipment volume is too large, and the manufacturing cost is high, which has certain limitations in actual use. Content of the Utility Model

[0003] In view of the above, the utility model provides a multi-station clamping turntable mechanism, which can improve work efficiency, streamline the equipment structure, reduce the volume and save costs when applied to automated processing or detection equipment.

[0004] The utility model specifically adopts the following technical solutions: A multi-station clamping turntable mechanism includes a turntable, a rotation driving mechanism for driving the turntable to rotate, a plurality of product clamping mechanisms and a lifting mechanism arranged on the turntable. The plurality of product clamping mechanisms are evenly distributed along the circumference of the turntable, each product clamping mechanism corresponds to a processing station, and a lifting mechanism is arranged below each processing station. The product clamping mechanism includes a product carrier plate, a positioning chuck, an adjusting shaft and a top column. The top column performs a lifting motion driven by the lifting mechanism. The adjusting shaft is a pair of sliding shafts symmetrically arranged with respect to the top column. During the lifting process of the top column, the sliding shafts are driven to move relatively closer or farther away from each other. The positioning chuck is connected to the sliding shafts and translates above the product carrier plate along with the movement of the sliding shafts.

[0005] Further, the sliding shafts are supported by positioning blocks, the sliding shafts are slidably arranged on the positioning blocks, the positioning chuck is connected to the sliding shafts through connecting plates, and a spring is connected between the connecting plates and the positioning blocks. The spring is sleeved around the sliding shafts.

[0006] Further, the top column includes a conical head and a column leg located below the conical head, and the column leg penetrates through the turntable.

[0007] Further, the product carrier plate is fixed on the turntable through a bottom plate.

[0008] Further, a product window is opened in the middle of the product carrier plate, and limiting claws are arranged at the edge of the product window.

[0009] Further, two retaining edges are oppositely arranged above the product carrier board, and the positioning chuck moves on the retaining edges.

[0010] Further, two cushion blocks are correspondingly arranged on both sides of the product carrier board. Guide rails are arranged on the cushion blocks, sliders are arranged at the bottom of the connecting plate, and the sliders are slidably connected with the guide rails in a matching manner.

[0011] Further, the jacking mechanism includes a cylinder, a mounting seat and a connecting seat. The connecting seat is arranged on the piston rod of the cylinder and can move up and down under its drive. The cylinder is supported and fixed through the mounting seat.

[0012] Further, a sensor assembly is correspondingly arranged for each working station.

[0013] The multi-station clamping turntable mechanism of the present utility model fixes products by arranging a plurality of product clamping mechanisms on the turntable. The rotary product transposition can make the processing or detection device using the mechanism of this application more compact in volume, and multiple working stations can work simultaneously to improve work efficiency. In addition, the product clamping mechanism uses a top column and a sliding shaft to drive the chuck to open and close, streamlining the structure above the turntable and avoiding the problems of cumbersome structures of multiple air pipes and air pipe channels, movement interference and high cost existing in the prior art when using a cylinder to control the opening and closing of the chuck.

[0018] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only parts related to the present utility model are shown in the drawings instead of all structures.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "arrangement" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0020] Referring to Figures 1 - 3 , a multi-station clamping turntable mechanism of this embodiment includes a turntable 1, a rotary drive mechanism 2 for driving the turntable to rotate, a plurality of product clamping mechanisms 3 arranged on the turntable 1, and a lifting mechanism 4. The plurality of product clamping mechanisms 3 are evenly distributed along the circumference of the turntable 1. Each product clamping mechanism 3 corresponds to a processing station, and a lifting mechanism 4 is arranged below each processing station. The product clamping mechanism 3 includes a product carrier plate 31, a positioning chuck 32, adjusting shafts, and a jacking column 33. The jacking column 33 performs a lifting motion driven by the lifting mechanism 4. The adjusting shafts are a pair of sliding shafts 34 symmetrically arranged with respect to the jacking column 33. During the lifting process of the jacking column 33, the sliding shafts 34 are driven to move relatively closer or farther away. The positioning chuck 32 is connected to the sliding shafts 34 and translates above the product carrier plate 31 along with the movement of the sliding shafts 34.

[0021] In this embodiment, referring to Figures 3 - 4 Specifically, the product carrier plate 31 is fixed on the turntable 1 through a bottom plate 30. Each sliding shaft 34 is supported above the bottom plate by two positioning blocks 35, and the sliding shaft 34 penetrates through the positioning blocks 35 and can slide horizontally thereon. At the same time, two cushion blocks 39 are correspondingly arranged on both sides of the product carrier plate 31. The cushion blocks 39 are fixed on the bottom plate 30, and guide rails 391 are arranged on the cushion blocks 39. The positioning chuck 32 is connected to the sliding shaft 34 through a connecting plate 36. One end of the connecting plate 36 is fixed on the sliding shaft 34, and the other end is slidably connected to the guide rail 391 through a slider 361 arranged at the bottom of the connecting plate 36, thereby driving the positioning chuck 32 to move. In addition, a spring 37 is connected between the connecting plate 36 and the positioning block 35, that is, both ends of the spring 37 are respectively fixed on the connecting plate 36 and the positioning block 35, and the spring 37 is sleeved around the sliding shaft 34.

[0022] The top column 33 includes a conical head 331 and a column leg 332 located below the conical head. The column leg 332 penetrates through the bottom plate 30 and the turntable 1. When the lifting mechanism 4 below the turntable 1 starts to push up against the column leg 332 to drive the entire top column 33 to rise, the two symmetrical sliding shafts 34 are gradually pushed apart by the conical head 331 and move away from each other, thereby driving the positioning chuck 32 to expand. When the lifting mechanism 4 descends and the top column 33 naturally descends, the sliding shafts 34 return to their original positions under the restoring force of the spring 37, thereby driving the positioning chuck 32 to tighten and clamp the product 100. A spring is sleeved around the column leg 332 to play a buffering role when the lifting mechanism 4 pushes the top column.

[0023] Further referring to Figure 4 , a product window 311 is formed in the middle of the product carrier plate 31. Limiting claws 312 extending towards the inner center are provided at the edge of the product window 311. Grooves 313 are provided on the limiting claws 312 to facilitate clamping the product. Two side edges 38 are oppositely arranged above the product carrier plate 31, and the positioning chuck 32 moves on the side edges 38.

[0024] Combined with Figures 1 - 2 , the rotation drive mechanism 2 in this embodiment preferably uses a torque motor, and the specific model of the rotation motor can be selected according to needs. The lifting mechanism 4 includes a cylinder 41, a mounting seat 42, and a connecting seat 43. The connecting seat 43 is arranged on the piston rod 411 of the cylinder 41 and can perform a lifting motion driven by it. The cylinder 41 is supported and fixed to the installation position through the mounting seat 42. During the process of the lifting mechanism pushing the top column 33 to move, the connecting seat 43 contacts and supports the column leg 332 of the top column. The connecting seat 43 is L-shaped, with one side connected to the piston rod 411 of the cylinder and the other side slidably connected to the side of the cylinder through a slide rail to improve the stability during lifting. In addition, a sensor assembly 300 (only part of which is shown in the drawing) is correspondingly arranged for each station to facilitate sensing and positioning when the turntable 1 rotates and changes positions.

[0025] The multi-station clamping turntable mechanism in this application has a simple structure. It designs a mechanical structure to drive the opening and tightening of the positioning chuck to clamp and fix the product. Compared with the prior art in which two cylinders are used to drive the two sides of the chuck to perform opening and closing movements respectively, it not only eliminates the tediousness of pipeline laying, but also does not need to consider whether there will be movement interference in multiple stations, saves more costs, and reduces the volume.

[0026] In addition, the above embodiments are only used to illustrate the present utility model and do not limit the technical solutions described in the present utility model. The understanding of this specification should be based on those skilled in the art. Although this specification has described the present utility model in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the art can still modify or equivalently replace the present utility model, and all technical solutions and their improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
