Description

Press fitting tool for movable iron push rod

Technical Field

The utility model relates to an electromagnet, in particular to a tool for pressing a push rod into a moving iron (armature) in electromagnet manufacturing, and belongs to the technical field of electromagnet manufacturing tools.

Background

In the production and manufacture of the electromagnet, a push rod is fixedly connected to a movable iron, a specific production process is that a central hole is machined in the movable iron, the push rod is tightly matched and inserted into the central hole, then the length of the push rod (the length of the movable iron is exposed) is adjusted to be required by design, then the push rod and the movable iron are riveted, when the length of the push rod is adjusted, a tool which is usually adopted is a standard length (height) block with a hole, also called a standard block, when the push rod is initially inserted into the central hole, the length of the push rod is larger than the designed length of the push rod, when the length is adjusted, the push rod is inserted into the hole of the standard block, the end face of the movable iron is contacted with the standard block, the length of the exposed standard block is required to be pressed into the movable iron, namely the push rod is pressed into the end part to be flush with the standard block, and the length of the push rod is adjusted in the current production, so that the length of the push rod has the following problems: because the types of electromagnets are different, the designed push rod lengths are also different, so that different standard blocks are required to be used for different push rod lengths, hundreds of push rod lengths corresponding to the types of the electromagnets are required, a large number of standard blocks are required to be prepared, the standard blocks are numbered, and corresponding standard blocks are selected when electromagnets of different types are produced, so that a large number of tools are required to be prepared and stored, and the novel push rod type electromagnet is high in cost, occupies space and is easy to lose.

Disclosure of Invention

The utility model aims to overcome the problems existing in the prior art that a push rod is pressed into a moving iron, and provides a moving iron push rod pressing tool.

In order to achieve the purpose of the utility model, the following technical scheme is adopted: the utility model provides a move indisputable push rod pressure equipment frock, includes one or more frock unit, the frock unit include a sleeve, the bottom fixedly connected with double-screw bolt in the sleeve, the periphery of double-screw bolt has the screw thread, has seted up the axial hole that supplies the push rod to pass on the double-screw bolt, has connect the thread bush soon on the double-screw bolt, the thread bush has the top surface, has seted up the perforation that corresponds with the axial hole on the top surface, has processed radial jackscrew hole on the sleeve outer wall, has connect the jackscrew soon in the jackscrew hole.

Further; the periphery of the thread sleeve is provided with scale marks.

Further; the sleeve is round, and the stud is positioned at the center of the sleeve.

Further; the press-fit tool comprises a plurality of tool units which are fixedly connected to a bottom plate.

The utility model has the positive and beneficial technical effects that: the distance between the top surface of the thread bush and the bottom surface of the sleeve can be adjusted by rotating the thread bush in the tool unit, so that standard blocks with different heights (lengths) are formed to adapt to the lengths of push rods of electromagnets with different types, the number and the cost of the standard blocks are greatly reduced, the storage space is not occupied basically, and the tool is not easy to lose.

Detailed Description

In order to more fully explain the practice of the utility model, examples of the practice of the utility model are provided. These examples are merely illustrative of the present utility model and do not limit the scope of the utility model.

The utility model will be explained in further detail with reference to the accompanying drawings, in which: 1: a sleeve; 2, a stud; 3: an axial bore; 4: a thread sleeve; 5: perforating; 6: a top thread hole; 7: a bottom plate.

As shown in the drawing, the tool for press fitting of the movable iron push rod comprises one or more tool units, wherein each tool unit comprises a sleeve 1, the sleeve is round, a stud 2 is fixedly connected in the sleeve, the stud is positioned at the center of the sleeve, threads are arranged on the periphery of the stud, an axial hole 3 for the push rod to pass through is formed in the stud, a threaded sleeve 4 is screwed on the stud, part or all of the length of the threaded sleeve is positioned in the sleeve, scale marks are arranged on the periphery of the threaded sleeve, the scale marks are not shown in the drawing, the scale marks can be omitted, under the condition that the scale marks are not arranged, the height (when the length) can be adjusted) by adopting a vernier caliper, then the tool units are put into the vernier caliper to be adjusted to be in place, the threaded sleeve is provided with a top surface, a perforation 5 corresponding to the axial hole is formed in the top surface, a radial jackscrew hole 6 is formed in the outer wall of the sleeve, and a jackscrew is screwed in the jackscrew hole.

As further optimization, the press-fit tool comprises a plurality of tool units, the tool units are fixedly connected to a bottom plate, so that a plurality of workpieces can be press-fitted at one time, and the working efficiency is improved.

When the push rod is used in the work, the jackscrew is loosened, the rotating thread sleeve is adjusted to the designed push rod length, and the push rod penetrates through the axial hole and the perforation to expose the top surface of the thread sleeve during press fitting, so that the exposed part is pressed into the movable iron.
