Description

Technical Field

[0001] This utility model relates to a magnetic core riveting fixture, and more particularly to a magnetic core riveting press device. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] A magnetic core is a magnetic material with high permeability. The core is usually cylindrical, and vertical grooves can be cut into the outer wall of the cylinder to hold steel balls or other structural components.

[0004] Its magnetic core has a precise and compact structure. Before installing the ball in the vertical slot of the magnetic core, it is generally necessary to rivet marks on the vertical slot to facilitate the insertion of the steel ball. The rivet marks are usually set as small notches that are relatively concave in the vertical slot, which increases the local width of the vertical slot, so that the steel ball can be easily squeezed into the vertical slot.

[0005] There is currently no method that can rivet marks onto the vertical slots with high precision, high efficiency, and minimal impact on the magnetic core.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0007] The purpose of this invention is to provide a magnetic core riveting press device that, through the cooperation of upper and lower tooling, allows the lower riveting head to be pushed by the upper riveting head to transform into a displacement relative to the sliding groove, thereby achieving high-precision riveting operations.

[0008] To achieve the above objectives, this utility model discloses a magnetic core riveting press device, wherein the outer wall of the magnetic core is provided with a concave vertical groove, and the magnetic core riveting press device includes: The lower tooling includes a riveting table and a lower riveting head. The riveting table is provided with a mounting groove for placing the magnetic core and a sliding groove provided on one side of the mounting groove for installing the lower riveting head. The lower riveting head is installed in the sliding groove, and the end of the lower riveting head is oriented toward the mounting groove. The side wall of the lower riveting head is provided with a first inclined surface. The upper tooling includes a bracket, a cylinder, and an upper riveting head. The cylinder is mounted on the bracket, and the upper riveting head is mounted on the output end of the cylinder. The cylinder is used to drive the upper riveting head to move vertically. The bottom of the upper riveting head is concave to form a second inclined surface. After the upper riveting head is pressed down, the second inclined surface abuts against the first inclined surface, pushing the lower riveting head to slide horizontally in the sliding groove and rivet the magnetic core in the mounting groove, so that a riveting mark is formed on the vertical groove.

[0009] As a further description of the above technical solution, the magnetic core has a plurality of vertical grooves spaced at equal angles, and the riveting table has a plurality of sliding grooves spaced at equal angles to match the number of vertical grooves, and a lower riveting head is installed in each of the sliding grooves.

[0010] As a further description of the above technical solution, the upper rivet head is configured as a cover shape, the second inclined surface is configured as a concave annular surface, and when the second inclined surface is pressed down, it simultaneously abuts against the first inclined surface of all the lower rivet heads.

[0011] As a further description of the above technical solution, the upper tooling also includes a pressing head, which is installed in the upper riveting head and is positioned towards the mounting groove. The pressing head is used to press the upper riveting head down and then press it against the top surface of the magnetic core to prevent the magnetic core from shaking during riveting.

[0012] As a further description of the above technical solution, the upper tooling also includes an elastic component, which is connected to the side of the pressing head away from the mounting groove. The elastic component is used to undergo elastic deformation and buffer the magnetic core after the pressing head comes into contact with the magnetic core.

[0013] As a further description of the above technical solution, the elastic component is configured as a metal helical spring, which has a limit compression state when the upper rivet head is at its lowest height.

[0014] As a further description of the above technical solution, the width of the second inclined plane is greater than the width of the first inclined plane, and the inclination angles of the second inclined plane and the first inclined plane are the same.

[0015] Based on the above technical solution, the beneficial effects of this utility model are as follows: This invention relates to a magnetic core riveting press device. Through the cooperation of upper and lower fixtures, the lower riveting head, pushed by the upper riveting head, is displaced relative to a sliding groove, achieving high-precision riveting operations. Specifically, after the upper riveting head presses down, its second inclined surface can slide against the first inclined surface of the lower riveting head. Since the lower riveting head is confined within the sliding groove, it is pushed by the upper riveting head and moves horizontally within the groove, ultimately causing the magnetic core at the end of the lower riveting head to be riveted with a mark. This device converts the ample downward pressure provided by the upper fixture into a precise horizontal riveting force for the lower riveting head, achieving a more accurate riveting effect and higher efficiency.

[0022] Please see Figure 1-4 This embodiment provides a magnetic core riveting press device, wherein the outer wall of the magnetic core 100 is provided with a concave vertical groove 200, and the magnetic core riveting press device includes: The lower tooling 1 includes a riveting table 11 and a lower riveting head 12. The riveting table 11 is provided with a mounting groove 111 for placing the magnetic core 100, and a sliding groove 112 provided on one side of the mounting groove 111 for mounting the lower riveting head 12. The lower riveting head 12 is installed in the sliding groove 112, and the end of the lower riveting head 12 is oriented toward the mounting groove 111. The side wall of the lower riveting head 12 is provided with a first inclined surface 121. Upper tooling 2 includes a bracket 21, a cylinder 22, and an upper riveting head 23. The cylinder 22 is mounted on the bracket 21, and the upper riveting head 23 is mounted on the output end of the cylinder 22. The cylinder 22 is used to drive the upper riveting head 23 to move vertically. The bottom of the upper riveting head 23 is concave to form a second inclined surface 231. The second inclined surface 231 is used to abut against the first inclined surface 121 after the upper riveting head 23 is pressed down, pushing the lower riveting head 23 to slide horizontally in the sliding groove 112 and rivet the magnetic core 100 in the mounting groove 111, so that a rivet mark 300 is formed on the vertical groove 200.

[0023] With the above structure, during use, the operator only needs to pre-place the magnetic core 100 in the mounting groove 11 of the riveting table 11. The magnetic core 100 itself is placed vertically, with the vertical groove 200 at the corresponding position of the magnetic core 100 facing the lower riveting head 12 in the mounting groove 111 on one side. During riveting, the cylinder 22 in the upper tooling 2 is activated, causing the cylinder 22 to drive the upper riveting head 23 to move towards the lower riveting head 12. During this process, the first inclined surface 121 moves downward and comes into contact with the second inclined surface 231. The inclination angles of the first inclined surface 121 and the second inclined surface 231 are the same. At the same time, the lower riveting head 12, where the first inclined surface 121 is located, is limited in the sliding groove 112 and cannot move vertically. Therefore, the second inclined surface 231 can move horizontally relative to the sliding groove 112 by pushing the first inclined surface 121, and the end of the lower riveting head 12 is pressed against the vertical groove 200, ultimately forming... Figure 4 The rivet marks shown.

[0024] The output end of the cylinder 33 described above can be configured as a motor shaft assembly for transmission, which drives the corresponding downstream component to reciprocate through the stroke motion.

[0025] Based on the above structure, the upper and lower tooling can cooperate to transform the lower riveting head 12 into a displacement relative to the sliding groove 112 under the push of the upper riveting head 23, thereby achieving high-precision riveting operations. Specifically, after the upper riveting head is pressed down, the second inclined surface 231 of the upper riveting head can slide and rub against the first inclined surface 121 of the lower riveting head 12. Since the lower riveting head 12 is confined in the sliding groove 112, the lower riveting head 12 will be pushed by the upper riveting head 23 and move horizontally in the sliding groove 112, ultimately causing the magnetic core 100 at the end of the lower riveting head 12 to be riveted with a rivet mark 300. In this device, the sufficient downward pressure provided by the upper tooling is converted into a precise horizontal riveting force for the lower riveting head 12, which can achieve a more accurate riveting effect and higher efficiency.

[0026] In the above structure, the width of the second inclined surface 231 is greater than the width of the first inclined surface 121, so that at least all of the first inclined surfaces 121 can contact and slide within the range of the second inclined surface 231. Furthermore, the second inclined surface 231 and the first inclined surface 121 have the same inclination angle, so there is a good fit between the two inclined surfaces, which facilitates smooth sliding and pushing between them.

[0027] In this application, the magnetic core 100 has a plurality of vertical grooves 200 spaced at equal angles, and the riveting table 11 has a plurality of sliding grooves 112 spaced at equal angles to match the number of vertical grooves 200. Each sliding groove 112 is fitted with a lower riveting head 12. Therefore, the riveting table 11 in this application actually has a plurality of centrally positioned lower riveting heads 12, arranged in a petal shape around the central mounting groove 111.

[0028] Furthermore, the upper riveting head 23 is configured as a cover shape, and the second inclined surface 231 is configured as a concave annular surface. When the second inclined surface 231 is pressed down, it simultaneously abuts against the first inclined surface 121 of all the lower riveting heads 12. In this application, the upper riveting head 23 in the upper tooling 2 can simultaneously compress all the lower riveting heads 12 with a complete annular surface, realizing that multiple lower riveting heads 12 can simultaneously rivet the magnetic core 100 at its center position at the same time. At the same time, because it is set around the center, the lateral force on the magnetic core 100 cancels each other out during the riveting process, making the horizontal position of the magnetic core 100 more stable, and realizing the formation of multiple rivets 300 in one riveting, which has high processing efficiency.

[0029] Please see Figure 3The schematic cross-sectional view of the magnetic core riveting press device shown illustrates that the upper tooling 2 further includes a pressing head 24, which is installed in the upper riveting head 23 and faces the mounting groove 111. The pressing head 24 is used to press the top surface of the magnetic core 100 after the upper riveting head 23 is pressed down to prevent the magnetic core 100 from shaking during riveting. The pressing head 24 itself can be made of an elastic material. During the pressing process of the upper riveting head 23, the pressing head 24 presses down synchronously, so that the pressing head 24 can contact the top of the magnetic core 100 during riveting and press the magnetic core 100 firmly into the mounting groove 111. Specifically, the upper tooling 2 further includes an elastic component 25, which is connected to the side of the pressing head 24 away from the mounting groove 111. The elastic component 25 is used to elastically deform and buffer the magnetic core 100 after the pressing head 24 comes into contact with the magnetic core 100. In other words, in this application, during the pressing process of the upper riveting head 23, the pressing head 24 can contact the top of the magnetic core 100 in advance and press it firmly. As the pressing head 24 presses down, the pressing force of the elastic component 25 on the top of the magnetic core 100 increases as the elastic component 25 undergoes extrusion deformation in the vertical direction, thus fully ensuring the stability of the magnetic core 100 during the riveting process.

[0030] The aforementioned elastic material can be a metal coil spring, which is in a state of ultimate compression when the upper rivet head 23 is at its lowest height. Metal coil springs themselves have stable material properties and low cost.
