Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switch machines, in particular to a pressing tool for a roller and a roller sleeve of an electric switch machine. Background Art
[0002] During the assembly and production process of the ZD6 electric switch machine, a press is required to press the roller and the roller sleeve. During the pressing process, the size of the pressed parts often deviates due to the movement of the roller sleeve, which affects the subsequent assembly process. At the same time, since the positions of the roller and the roller sleeve are not fixed during the pressing process, there are certain safety hazards to the operators, and the production efficiency is low. Summary of the Utility Model
[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the technology and provide a pressing tool for a roller and a roller sleeve of a ZD6 electric switch machine. During the pressing operation of the roller and the roller sleeve, the relative positions of the two are fixed, so that the reference is consistent, and the accuracy of the pressed finished size is ensured.
[0004] To achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A pressing tool for a roller and a roller sleeve of an electric switch machine includes a guide rod, a base, a compression spring and a threaded plug. The guide rod is composed of a first stepped rod, a second stepped rod and an end cap connected in sequence. The outer diameter of the first stepped rod matches the inner diameter of the roller sleeve, and the second stepped rod matches the inner diameter of the roller. A threaded hole is provided inside the base, and a through hole connected to it is provided above the threaded hole. The second stepped rod passes through from below the through hole, and the end cap is stuck at the lower end of the through hole. The compression spring is placed below the end cap, and the threaded plug is threadedly connected to the lower part of the threaded hole to limit the compression spring in the threaded hole.
[0006] Preferably, a chamfer is provided at the end of the first stepped rod.
[0007] Preferably, the lower end of the threaded plug is flush with the bottom of the base.
[0008] The beneficial effect of the utility model is that when using the utility model for the pressing and assembling process of the roller and the roller sleeve of the ZD6 electric switch machine, the roller and the roller sleeve are sequentially inserted into the guide rod, and the relative positions of the two can be fixed, avoiding the deviation of the size of the pressed parts caused by the movement of the roller sleeve. At the same time, the production efficiency can be improved, and the operators can be prevented from being accidentally injured. Brief Description of the Drawings
[0009] Figure 1 It is a schematic structural diagram of the pressing tool for a roller and a roller sleeve of the ZD6 electric switch machine provided by the utility model;
[0010] Figure 2 Schematic diagram of the working state of the pressing tool for the roller and roller sleeve of the ZD6 electric switch machine provided by the present utility model. Specific embodiments
[0011] The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. As Figure 1 shown, a pressing tool for the roller and roller sleeve of an electric switch machine includes a guide rod 1, a base 2, a compression spring 3, and a threaded plug 4. The guide rod is composed of a first stepped rod 5, a second stepped rod 6, and an end cap 7 connected in sequence. The outer diameter of the first stepped rod matches the inner diameter of the roller sleeve, and the second stepped rod matches the inner diameter of the roller. A threaded hole 8 is provided inside the base, and a through hole 9 connected thereto is provided above the threaded hole. The second stepped rod passes through from below the through hole, and the end cap is stuck at the lower end of the through hole. The guide rod 1 is inserted into the threaded hole of the base 2 through the first stepped rod. The compression spring 3 is installed in the threaded hole of the base 2 and fixed to the end cap 7 of the guide rod 1. The threaded plug 4 is screwed into the threaded hole of the base 2 until the bottom ends are flush.
[0012] As Figure 2 shown, when using the present utility model to perform the pressing and assembling process of the roller and roller sleeve of the ZD6 electric switch machine, the roller and the roller sleeve are sequentially inserted into the guide rod 1. When the press works, the roller sleeve is inserted into the roller under the action of pressure. At the same time, the guide rod 1 moves downward together with the roller sleeve relative to the base 2 under the action of pressure, and compresses the compression spring 3. During the whole movement process, the guide rod 1 can always provide positioning for the roller and the roller sleeve. When the press head is lifted, the compression spring 3 restores and pushes the guide rod 1 to move upward relative to the base 2, and at the same time drives the pressed workpiece to move upward, and the workpiece is taken off, thus completing the whole pressing process of the roller and the roller sleeve.
[0013] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
