Description

Technical Field

[0001] The utility model relates to the technical field of an electromagnet frame, in particular to an electromagnet frame with a pre-tightening mechanism. Background Art

[0002] When the current electromagnet skeleton is installed on the magnetic suction seat, it is often necessary to use an O-ring or other similar elastic items as a pre-tightening member to ensure that the electromagnet is stably installed in the magnetic suction seat. However, in the actual installation process, when the electromagnet skeleton is installed on the magnetic suction seat, the O-ring may be skewed during the squeezing process, which can easily cause one side of the electromagnet skeleton to tilt and warp after installation. Therefore, its pre-tightening effect is relatively unsatisfactory, and the installation procedure is relatively troublesome. Utility Model Content

[0003] The utility model provides an electromagnet frame with a pre-tightening mechanism, which solves the above-mentioned problems existing in the use process of the prior art.

[0004] The technical solution of the utility model is implemented as follows: an electromagnet skeleton with a pre-tightening mechanism, comprising a skeleton body, a mounting channel is opened inside the skeleton body, an annular pre-tightening ring is extended from the inner side wall of the mounting channel toward the axial direction, the pre-tightening ring is integrally formed with the skeleton body, the inner diameter and the outer diameter of the annular pre-tightening ring are both reduced from the lower edge, and the electromagnet skeleton is nylon plastic.

[0005] The utility model is further configured as follows: a pre-tightening sheet is arranged on the end of the pre-tightening ring, and the pre-tightening sheets form a group of two and are symmetrically arranged around the axis of the safety channel.

[0006] The utility model is further configured as follows: the inner side wall of the pre-tightening sheet is an arc-shaped surface.

[0007] The utility model is further configured as follows: a plurality of groups of pre-tightening sheets are arranged on the pre-tightening ring.

[0008] The utility model is further configured as follows: a first abutment piece is extended outwardly from the back side of the pre-tensioning piece, the angle between the first abutment piece and the pre-tensioning piece is set at an oblique angle, and the end of the first abutment piece is used to abut against the side wall of the installation channel.

[0009] The utility model is further configured as follows: a second contact piece is extended from the inner side wall of the safety channel toward its axial direction, the included angle between the second contact piece and the side wall of the safety channel is set at an oblique angle, the contact pieces are grouped in pairs and are symmetrically arranged around the axis of the safety channel, and the end of the second contact piece is used to abut against the back side of the pre-tensioning piece.

[0010] The utility model is further configured as follows: the number of groups of the second contact pieces is the same as the number of groups of the pre-tensioning pieces.

[0011] In summary, the beneficial effects of the present invention are:

[0012] 1. The material of the preload ring is nylon plastic, the same as the electromagnet frame, and it has a certain elasticity. When the frame body is installed on the magnetic seat, you only need to press the frame body downward, and the preload ring can be stretched and held against the side of the magnetic seat. At the same time, because the preload ring is elastic, it can just fix the electromagnet frame on the magnetic seat while contracting. This method can not only speed up the installation speed of the frame body, but also have a good preload effect, and will not cause one end of the electromagnet frame to tilt after installation.

[0013] 2. The pre-tightening piece, the first contact piece and the second contact piece can increase the pre-tightening force of the frame body on the magnetic suction seat, so that the frame body can be more firmly installed on the magnetic suction seat. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example:

[0021] like Figures 1 to 3 As shown, the utility model discloses an electromagnet skeleton with a pre-tightening mechanism, including a skeleton body 1, an installation channel 11 is opened inside the skeleton body 1, and an annular pre-tightening ring 21 is extended from the inner side wall of the installation channel 11 to the axial direction, and the angle between the pre-tightening ring 21 and the side wall of the installation channel 11 is set at an oblique angle, and the inner diameter and outer diameter of the pre-tightening ring 21 are both reduced from the lower edge. In this structure, the electromagnet skeleton is nylon plastic, and the pre-tightening ring 21 is integrally formed by the skeleton body 1.

[0022] A pre-tensioning plate 22 is arranged at the end of the pre-tensioning ring 21, and the inner wall of the pre-tensioning plate 22 is an arc-shaped surface. In this structure, a plurality of pre-tensioning plates 22 are arranged and every two pre-tensioning plates 22 form a group. Each group of pre-tensioning plates 22 is preferably distributed equidistantly along the circumferential direction on the pre-tensioning ring 21. At the same time, the two pre-tensioning plates 22 in each group of pre-tensioning plates 22 are symmetrically arranged with respect to the axis of the safety passage.

[0023] A first abutment piece 23 extends outward from the back of each pre-tensioning piece 22 . At the same time, the angle between the first abutment piece 23 and the pre-tensioning piece 22 is set at an oblique angle. In this structure, the end of the first abutment piece 23 is used to abut against the side wall of the installation channel 11 .

[0024] The inner side wall of the safety passage has a second contact piece 24 extending toward its axial direction, and the contact pieces are grouped together in pairs and are symmetrically arranged about the axis of the safety passage. The number and positions of the second contact pieces 24 correspond to the number and positions of the pre-tensioning pieces 22. In this structure, the end of the second contact piece 24 is used to abut against the back side of the pre-tensioning piece 22. At the same time, the angle between the second contact piece 24 and the side wall of the safety passage is set at an oblique angle.

[0025] The pre-tightening piece 22 , the first contact piece 23 and the second contact piece 24 are all formed integrally with the frame body 1 .

[0026] The working principle of the above structure is: when the skeleton body 1 is to be installed on the magnetic seat, the skeleton body 1 can be directly aligned with the magnetic seat and pressed downward. At this time, the pre-tightening ring 21 and the pre-tightening plate 22 in the installation channel 11 are both stretched open by the magnetic seat, and the skeleton body 1 can continue to move downward. After the skeleton body 1 is installed, the pre-tightening ring 21 and the pre-tightening plate 22 are pressed on the side wall of the magnetic seat and thereby pre-tighten the skeleton body 1 on the magnetic seat. At the same time, in order to further strengthen the pre-tightening force, the first contact plate 23 and the second contact plate 24 can also press the pre-tightening plate 22 on the side wall of the magnetic seat.
