[0024] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0026] Example 1

[0027] like Figures 1 to 4 As shown, a fixture for processing piston rod components includes a base plate 1, and lifting ears 20 are installed at the four corners of the base plate 1, which can be easily lifted and moved. A group of clamping components 1 2 is installed on one side of the upper end of the base plate 1, and a clamping component 2 3 is installed on the upper end of the base plate 1. There are five groups of clamping components 2 3, and the sizes of the five groups of clamping components 2 3 decrease gradually. The angular positioning component 4 is connected to the clamping component 2 3 and corresponds one-to-one with the clamping component 2 3.

[0028] The clamping assembly 2 includes a fixed seat 15 and a fixed seat 29. The fixed seat 15 is fixedly installed on the upper end of the base plate 1. There are two groups of fixed seats 5, and the two groups of fixed seats 5 are placed at ninety degrees. A rotating cylinder 6 is fixedly installed on the upper end of the fixed seat 5. A connecting plate 7 is installed on the upper end of the rotating cylinder 6. The rotating cylinder 6 can drive the connecting plate 7 to rotate. A dynamic steel ball positioning screw 8 is installed on the lower side of the other end of the connecting plate 7. The rotation of the connecting plate 7 can drive the dynamic steel ball positioning screw 8 to rotate. The fixed seat 29 is fixedly installed on the upper end of the base plate 1. There are two groups of fixed seats 29, and the two groups of fixed seats 29 are placed at ninety degrees. A V-shaped block 10 is fixedly installed on the upper end of the fixed seat 29, and two groups of V-shaped blocks 10 are symmetrically installed on the upper end of one of the fixed seats 29, and are perpendicular to the direction of the V-shaped block 10 on the other fixed seat 29.

[0029] The clamping assembly 2 is used to clamp and fix the piston rod with a handle. The piston rod is T-shaped as a whole. The short rod of the piston rod is placed on the upper end of two V-shaped blocks 10 in the same direction, and the long rod of the piston rod is placed on the upper end of another V-shaped block 10. At this time, the two sets of rotating cylinders 6 are started to drive the connecting plate 7 to rotate, so that the moving steel ball positioning screw 8 is located on the axis of the piston rod. The moving steel ball positioning screw 8 is rotated so that the lower end of the moving steel ball positioning screw 8 presses the surface of the upper end of the piston rod, which can complete the fixation and processing.

[0030] It should be noted that threaded holes are provided inside the chuck 16, and threaded support screws 19 are installed inside the threaded holes. The upper end of the support screw 19 is supported on the lower end of the piston rod long rod to support the piston rod. At this time, the chuck 16 can be used to clamp the sleeve. The connection between the V-shaped block 10 and the fixing seat 9 is fixed by bolts. Therefore, when piston rods of different diameters need to be processed, different V-shaped blocks 10 can be replaced.

[0031] The clamping assembly 2 3 includes a fixed seat 3 11, which is fixedly installed on the upper end of the base plate 1, and a rotating cylinder 2 12 is fixedly installed on the upper end of the fixed seat 3 11. A connecting plate 2 13 is installed on the upper end of the rotating cylinder 2 12, and a dynamic steel ball positioning screw 2 14 is installed on the lower side of the other end of the connecting plate 2 13. A base 15 is installed between the two fixed seats 3 11, and a chuck 16 is installed on the upper end of the base 15.

[0032] The sizes of the five groups of clamping components 2 3 decrease in sequence. When it is necessary to clamp and fix the sleeve, the relatively large sleeve is fixed by the large-sized clamping component 2 3. The specific operation is: place the sleeve horizontally on the chuck 16, start the rotating cylinder 2 12, and drive the connecting plate 2 13 to rotate, so that the connecting plate 2 13 is away from one end of the rotating cylinder 2 12 to clamp the sleeve. At this time, the dynamic steel ball positioning screw 2 14 will not be used.

[0033] The relatively small sleeve is fixed by a small-sized clamping component 23. The specific operation is: place the sleeve horizontally on the chuck 16, start the rotating cylinder 212, drive the connecting plate 213 to rotate, drive the dynamic steel ball positioning screw 214 to rotate to the top of the sleeve, and rotate the dynamic steel ball positioning screw 214 so that the lower end of the dynamic steel ball positioning screw 214 clamps the sleeve.

[0034] The angular positioning assembly 4 includes a connecting rod 17, which is L-shaped. One end of the connecting rod 17 is fixedly mounted on one end of the base 15, and the other end of the connecting rod 17 is installed with an angular positioning screw 18. The angular positioning screw 18 is threadedly connected to the connecting rod 17. The angular positioning screw 18 can rotate and move inside the connecting rod 17. One end of the angular positioning screw 18 contacts one side of the sleeve for positioning the sleeve and for calibrating the horizontal placement angle of the sleeve.

[0035] The rotary cylinders used above are all existing technologies, and the specific principles will not be described again.

[0036] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
