Description

Technical Field

[0001] The utility model belongs to the technical field of motor assembly, and particularly relates to a profiling die head for adsorbing spring pieces. Background Art

[0002] The motor bracket assembly is composed of parts such as a bracket, felt, bearings, and shrapnel. These parts need to be placed in the bracket in order and then riveted to form a bracket assembly. The main function of the shrapnel is to fix the felt and the bearing to prevent them from falling off. Specifically, the existing motor bracket assembly is generally assembled using a bracket riveting machine. The die head of the bracket riveting machine has a built-in magnet. When the vibration plate transports the shrapnel to the position of the discharge port, the bracket riveting machine absorbs the shrapnel through the built-in magnet and then transports it to the bracket. However, if the magnetic force of the magnet is too large or the shrapnel is too thin, the magnet adsorption sometimes absorbs two shrapnel at the same time, causing the two shrapnel to be placed in the bracket together, affecting the next riveting process, resulting in poor riveting, waste of materials, etc., and when it is manually identified that multiple shrapnel are placed in the bracket at the same time, the machine needs to be stopped, and the excess material needs to be taken out and then restarted, which greatly reduces production efficiency. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the utility model is to provide a contoured die head for adsorbing spring pieces, so as to solve the technical problem that when the existing motor bracket assembly is assembled, two spring pieces are easily assembled into the bracket at the same time through magnet adsorption, resulting in poor riveting and waste of materials in the next riveting process, and when it is manually identified that multiple spring pieces are placed in the bracket at the same time, the machine needs to be stopped, the excess material needs to be taken out and then the machine needs to be restarted, which greatly reduces the production efficiency.

[0005] (II) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A contour die for absorbing spring pieces, comprising: a die body, the shape of the lower end face of which matches the shape of the spring piece, comprising: a step face located in the middle and convex outward, an inclined face connecting the step face and extending obliquely, and a horizontal face connecting the inclined faces and extending horizontally, wherein a plurality of first suction holes for absorbing the spring piece are arranged circumferentially on the lower end face of the die body;

[0008] The die head of the present application is provided with a first suction hole on the lower end face, and uses suction to adsorb and fix the spring piece, so as to avoid the situation that two spring pieces are easily sucked up at the same time by magnetic adsorption, which leads to poor riveting and waste of materials in subsequent processing, etc., and by setting the lower end face of the die head to a combination of a step surface, an inclined surface and a horizontal surface, which cooperates with the shape of the spring piece, the lower end face of the die head can be completely in contact with the spring piece during adsorption, thereby ensuring the stability of adsorption.

[0009] In some embodiments, the first air suction holes are circumferentially arranged on the inclined surface.

[0010] In some embodiments, a second air suction hole is provided on the step surface;

[0011] By opening a second air suction hole in the middle of the die head to cooperate with the first air suction hole, the stability of adsorption can be further increased.

[0012] In some embodiments, an air channel communicating with the first air suction hole is opened in the die body corresponding to each first air suction hole;

[0013] Since each first air suction hole is connected to an airway, mutual interference of air pressure can be avoided, ensuring that each first air suction hole is at the same negative pressure, and the shrapnel can be stably adsorbed.

[0014] In some embodiments, the second suction hole has a larger diameter than the first suction hole.

[0015] Increasing the aperture of the second air suction hole can enhance the suction force of the second air suction hole and ensure the stability of the air suction.

[0016] In some embodiments, the first air suction hole is an elongated hole;

[0017] By arranging the first air suction hole into a long strip structure, the contact area between the first air suction hole and the spring sheet is increased, thereby improving the stability during adsorption. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] The utility model provides a contour die for absorbing spring pieces, comprising: a die body 1, the shape of the lower end face of which matches the shape of the spring piece, comprising: a step surface 101 located in the middle and protruding outward, an inclined surface 102 connecting the step surface 101 and extending obliquely, and a horizontal surface 103 connecting the inclined surface 102 and extending horizontally, wherein a plurality of first suction holes 104 for absorbing spring pieces are circumferentially arranged on the lower end face of the die body 1.

[0024] Specifically, the present application arranges the first suction holes 104 circumferentially on the inclined surface 102 , so as to adsorb the surrounding walls of the spring sheet.

[0025] Specifically, an air channel 106 connected to the first air suction hole 104 is opened in the die body 1 corresponding to each first air suction hole 104, and the multiple air channels 106 are all connected to the vacuum generating device. When the vacuum generating device is started, the air channel 106 and the first air suction hole 104 can be evacuated to form a negative pressure at the first air suction hole 104, and the die body 1 can absorb the shrapnel under atmospheric pressure.

[0026] Preferably, the present application further provides a second suction hole 105 on the step surface 101. Specifically, the second suction hole 105 is connected to the first suction hole 104, so that the vacuum generating device can be connected to the second suction hole 105, and the second suction hole 105 adsorbs the front of the spring piece, and the second suction hole 105 and the first suction hole 104 cooperate with each other to adsorb the spring piece from two dimensions.

[0027] Preferably, since the front area of ​​the end surface of the spring is relatively large, the present application sets the aperture of the second air suction hole 105 to be larger than that of the first air suction hole 104, so that the spring can be stably adsorbed.

[0028] Preferably, the present application sets the first air suction hole 104 as a long strip hole to increase the adsorption area of ​​the first air suction hole 104 and improve the suction force.

[0029] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
