Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of cast iron parts, in particular to a positioning device for production and processing of cylindrical cast iron parts which is easy to operate. Background Art

[0002] During the processing of cast iron parts, the cast iron parts need to be fixed to facilitate operators to perform grinding, painting, polishing and other operations.

[0003] Referring to the existing patent publication number: CN212596623U, a positioning device for the production and processing of cylindrical cast iron parts that is easy to operate, includes a sleeve, and a tightening device is provided on the top of the sleeve. Through the cooperation between the base, the threaded rod, the vertical rod, the support rod and the sleeve, the positioning device for the production and processing of cylindrical cast iron parts that is easy to operate not only realizes the fixation of the cylindrical cast iron parts, but also has an extremely simple operation process. The variable range of the distance between the three support rods is large. Through the cooperation between the circular plate, the support leg, the bottom plate, the pin and the second slider, the positioning device for the production and processing of cylindrical cast iron parts that is easy to operate can still rotate the angle of the cylindrical cast iron parts after the cylindrical cast iron parts are fixed, which is convenient for the operators to carry out processing and reduces the difficulty of the operators' operations.

[0033] Reference Figure 1-5 , a positioning device for the production and processing of cylindrical cast iron parts that is easy to operate, comprising: a sleeve 2, whose internal structure has an installation space of a certain depth; an upper positioning part 3, which is coaxially arranged with the sleeve 2 and connected in the installation space of the internal structure of the sleeve 2 and has a horizontal height higher than the horizontal height of the sleeve 2, and the upper positioning part 3 moves vertically relative to the sleeve 2; a lower positioning part 4, which is symmetrically distributed along the longitudinal axis center line of the sleeve 2 and arranged on both sides of the surface of the sleeve 2, and the lower positioning part 4 moves horizontally relative to the sleeve 2, so as to perform three-point positioning and fixing of the cylindrical cast iron part through the upper positioning part 3 and the lower positioning part 4, thereby improving stability; an adjusting component is installed on the upper part of the upper positioning part 3, and the adjusting component can adjust the relative use height of the upper positioning part 3 to adapt to cylindrical cast iron parts of different specifications, avoid difficulty in positioning and fixing different cylindrical cast iron parts, and improve the use effect, and a transmission component is installed inside the sleeve 2, through which the vertical direction of the upper positioning part 3 can be transmitted to the position of the lower positioning part 4 and the lower positioning part 4 can be horizontally moved.

[0034] Specifically, refer to Figure 3-5The transmission assembly includes: a bracket 9, a slide bar 6, a first connecting member 10, a second connecting member 14, a movable portion 11 and a rotating portion 12; the bracket 9 is installed at the lower end of the upper positioning portion 3 located in the sleeve 2, the slide bar 6 passes through the bracket 9 and is connected to the inner side of the sleeve 2, the movable portion 11 is installed on one side of the lower positioning portion 4 and passes through the mounting control structured inside the sleeve 2, the rotating portion 12 is installed at one end of the movable portion 11 located in the sleeve 2, the first connecting member 10 is connected between one rotating portion 12 and the slide bar 6, and the second connecting member 14 is connected between the other rotating portion 12 and the slide bar 6. Through this embodiment, after the cylindrical cast iron piece is put on the sleeve 2 and pressed down hard, the upper positioning portion 3 can be The upper positioning part 3 can move downward and drive the lower positioning part to move horizontally under the action of the transmission assembly. The upper positioning part 3 will drive the slide bar 6 to move downward in the slide groove 5 through the bracket 9. At this time, the slide bar 6 can drive the first connecting member 10 and the second connecting member 14 to move downward and rotate, so that the first connecting member 10 and the second connecting member 14 can push the movable part 11 and the lower positioning part 4 to move horizontally during the rotation, so that the lower positioning part 4 can be opened to support and fix the workpiece. Furthermore, the lower positioning part 4 adopts an electromagnet to strongly adsorb the workpiece. Under the action of the electromagnet, the cast iron part can be strongly fixed to avoid movement, improve the connection strength of the cylindrical workpiece, and facilitate operation.

[0035] Specifically, refer to Figure 3-4 An elastic member 13 is installed between one end of the movable portion 11 located inside the sleeve 2.

The upper positioning part 3 will drive the slide bar 6 to move downward in the slide groove 5 through the bracket 9. At this time, the slide bar 6 can drive the first connecting member 10 and the second connecting member 14 to move downward and rotate, so that the first connecting member 10 and the second connecting member 14 can promote the movable part 11 and the lower positioning part 4 to move horizontally during the rotation process. The lower positioning portion 4 can be moved so that the lower positioning portion 4 can be opened to support and fix the workpiece, and the lower positioning portion 4 adopts an electromagnet to strongly adsorb the workpiece to avoid movement, thereby improving the connection strength of the cylindrical workpiece, and is easy to operate, reducing the steps of frequent operations by personnel, and when positioning and fixing cylindrical cast iron parts of different specifications, the staff can rotate the adjusting portion 7 so that the adjusting portion 7 can move up and down under the action of the thread 8, thereby adjusting the height of the upper positioning portion 3 to match the lower positioning portion 4, so as to position and fix cylindrical cast iron parts of different specifications.
