Description

Technical Field

[0001] The utility model belongs to the technical field of positioning tooling, and in particular relates to a positioning tooling for gear forgings. Background Art

[0002] Gear transmission is one of the most common and important transmission modes in mechanical transmission. Tooling is a process device used to quickly tighten the workpiece during processing so that the machine tool, cutting tool and workpiece maintain the correct relative position. In the subsequent surface processing of gear forgings, the gears are clamped and limited by tooling.

[0003] The existing gear positioning tooling generally uses a three-jaw chuck to position the inner hole of the gear forging. Different gears have different inner holes. During surface treatment, the existing tooling (three-jaw chuck) cannot quickly and conveniently complete the installation of gears of different specifications. It is necessary to remove the jaws and replace them with different matching jaws. The disassembly and installation process wastes a lot of time and reduces the processing production efficiency.

[0004] Therefore, in order to solve the above problems, it is necessary to design a positioning tool for gear forgings. Utility Model Content

[0005] The utility model aims to provide a positioning tool for gear forgings to solve the technical problem that the existing tool is complicated in installing gear forgings of different specifications.

[0006] In order to solve the above technical problems, the utility model provides a positioning tool for gear forgings, comprising:

[0007] A bottom plate, comprising: at least two first long through holes and at least two second long through holes;

[0008] At least two positioning components, which include: two positioning blocks slidably connected to the first long through hole, two sliders slidably connected to the second long through hole, and a bidirectional screw rod meshed with the two sliders; wherein

[0009] The positioning block is arranged above the sliding block; and

[0010] The positioning block protrudes from the upper surface of the bottom plate;

[0011] The bidirectional screw is suitable for driving the two sliders to slide in the second long through hole and move away from each other when rotating, so as to drive the two positioning blocks to move away from each other, so as to position and fix the gear forging to be processed.

[0012] Furthermore, the positioning block comprises: an arc portion and a flat portion; wherein

[0013] The two positioning blocks are cylindrical when the plane parts are in contact with each other; and

[0014] The arc portion is suitable for contacting with the gear forging to be processed.

[0015] Furthermore, the positioning assembly further comprises: handles arranged at both ends of the bidirectional screw;

[0016] The handle is suitable for driving the bidirectional screw to rotate when rotating.

[0017] Further, the bottom plate comprises: a first plate;

[0018] The first long through hole is opened on the first plate.

[0019] Further, the bottom plate further comprises: a second plate arranged at the bottom of the first plate;

[0020] The second long through hole includes: a first long groove opened at the bottom of the first plate and a second long groove opened at the top of the second plate.

[0021] Further, at least two countersunk through holes are formed on the first plate;

[0022] The second plate is provided with at least two mounting through holes;

[0023] The countersunk through hole and the mounting through hole are concentrically arranged.

[0024] The beneficial effects of the utility model are:

[0025] (I) In the initial state of the utility model, the two positioning blocks are in contact with each other at the flat surface and are cylindrical. The gear forging to be processed is sleeved on the cylinder. By rotating the handle in the forward direction, the handle drives the bidirectional screw to rotate forward. The bidirectional screw meshes with the two sliders to drive the two sliders to slide in the second long through hole and move away from each other. The two sliders drive the positioning blocks to move away from each other to abut against the gear forging to be processed. Through the above steps, the gear forging to be processed can be quickly positioned and fixed to adapt to gear forgings of different specifications without disassembling the tooling, thereby improving the processing efficiency.

[0026] (ii) The utility model achieves the effect of facilitating the processing of the first long through hole by dividing the bottom plate into the first plate and the second plate; wherein the second long through hole is composed of a first long groove on the first plate and a second long groove on the second plate, thereby achieving the effect of facilitating the processing of the second long through hole.

[0027] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by practicing the utility model. The purpose and other advantages of the utility model are realized and obtained by the structures particularly pointed out in the description and the drawings.
