Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling technology, specifically to a manually indexable tooling. Background Technology
[0002] A pilot valve is a control valve commonly used in hydraulic systems to control the flow of the main fluid. During manufacturing, pilot valves typically require clamping and fixing them onto a rotary tool, which is then mounted on a machine tool for machining. Traditional rotary tooling lacks an effective locking mechanism, making it prone to wobbling after angle adjustment during subsequent machining. This inaccurate positioning leads to inconsistent quality in the finished pilot valve. Furthermore, existing precision rotary tooling is expensive and complex to operate, requiring specially trained personnel and increasing labor costs. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model proposes a manually indexable tooling.
[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:
[0005] A manually operable indexable fixture includes a base, a worktable fixedly connected to the base, a rotating plate disposed on the worktable, and an angle scale disposed on the worktable. The angle scale and the rotating plate are arranged concentrically. A rotating mechanism connected to the rotating plate is disposed on the worktable, and a clamping mechanism is disposed on the rotating plate.
[0006] The beneficial effects of this utility model are:
[0007] This utility model provides a manually operable indexable fixture, which features a rotating mechanism and rotating plate that can be rotated manually. Compared with existing precision indexable fixtures, it is easier to operate, requires no special training, and reduces labor costs. By setting up a rotating handwheel that can slide up and down, a limiting block set at the bottom of the rotating handwheel, and a limiting groove set on the worktable, the workpiece can be locked after the angle is adjusted. This solves the problem in traditional indexable fixtures where the rotating mechanism lacks an effective locking mechanism, which makes it easy for the rotating mechanism to wobble during subsequent processing after the angle is adjusted, resulting in inaccurate positioning and inconsistent quality of the pilot valve after processing.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0016] like Figures 1 to 5 As shown, a manually indexable tooling includes a base 1, a worktable 2 fixedly connected to the base 1, a rotating plate 3 disposed on the worktable 2, and an angle scale 4 disposed on the worktable 2. The angle scale 4 and the rotating plate 3 are arranged concentrically. The worktable 2 is provided with a rotating mechanism connected to the rotating plate 3, and the rotating plate 3 is provided with a clamping mechanism. In this embodiment, the base 1 has a square plate structure, and the four sides of the base 1 are chamfered. The base 1 serves to support and carry the tooling components. Further, the base 1 has threaded holes 5 around its perimeter, with three threaded holes 5 at each corner. This tooling can be fixedly connected to a machine tool through the threaded holes 5. In this embodiment, the worktable 2 has a square box structure, and the rotating plate 3 and the angle scale 4 are both disposed on the upper surface of the worktable 2.
[0017] As a further improvement to this embodiment, the rotating mechanism includes a geared disc 6 located inside the worktable 2 and coaxially connected to the bottom of the rotating plate 3, and a gear 7 located inside the worktable 2 and meshing with the geared disc 6. The gear 7 is coaxially connected to a rotating shaft 8 extending outside the worktable 2, and a rotating handwheel 9 is mounted on the upper part of the rotating shaft 8. Specifically, a connecting shaft is provided at the bottom of the rotating plate 3, the connecting shaft is rotatably mounted on the worktable 2, and the lower shaft portion of the connecting shaft is located inside the worktable 2. The geared disc 6 is coaxially connected to the lower shaft portion of the connecting shaft, and the rotating shaft 8 is vertically distributed and rotatably mounted on the worktable 2.
[0018] Furthermore, a vertical guide groove 10 is provided on the side wall of the rotating shaft 8, and a sliding block 11 is provided on the rotating handwheel 9. The sliding block 11 is slidably installed in the vertical guide groove 10. Specifically, the vertical guide groove 10 is provided on the left side wall of the upper part of the rotating shaft 8, and the length of the vertical guide groove 10 is required to be much larger than the size of the sliding block 11. The sliding block 11 and the rotating handwheel 9 are an integral structure. The sliding block 11 and the vertical guide groove 10 serve two purposes: firstly, to enable the rotating handwheel 9 to drive the rotating shaft 8 to rotate; secondly, to provide guidance when the rotating handwheel 9 slides up and down along the rotating shaft 8.
[0019] Furthermore, a limiting block 12 is fixedly connected to the bottom side of the rotary handwheel 9, and a limiting groove 13 adapted to the bottom of the rotary handwheel 9 and the limiting block 12 is provided on the worktable 2 below the rotary handwheel 9. Specifically, the limiting block 12 is located on the right side of the bottom of the rotary handwheel 9 and is an integral structure with the rotary handwheel 9; the limiting block 12 cooperates with the limiting groove 13 to restrict the rotation of the rotary handwheel 9, so that the rotating mechanism does not shake during subsequent processing, thus preventing it from affecting the processing angle; this solves the problem of inconsistent quality of the pilot valve after processing due to inaccurate positioning.
[0020] As a further improvement of this embodiment, the clamping mechanism includes two clamping bases 14 symmetrically distributed on the rotating plate 3, two threaded rods 15 symmetrically distributed horizontally on the two clamping bases 14, a clamping arc plate 16 movably mounted on the opposite inner rod ends of the two threaded rods 15, and a rotating handwheel 17 provided on the opposite outer rod ends of the two threaded rods 15.
[0021] Working principle and usage process of this utility model:
[0022] In use, the tooling is connected to the machine tool through the connecting threaded hole 5; then the pilot valve product is clamped and fixed on the rotating plate 3 through the clamping mechanism. Next, the rotating handwheel 9 is manually turned, which drives the gear plate 6 to rotate through the gear 7, so that the rotating plate 3 rotates. The processing angle of the pilot valve product is adjusted according to the angle scale 4. After the processing angle is adjusted, the rotating handwheel 9 is pressed down so that the bottom of the rotating handwheel 9 and the limit block 12 are engaged in the limit groove 13, which restricts the rotation of the rotating mechanism.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
