Description

Technical Field

[0001] This utility model relates to the field of brush bristle bending, and more specifically, to an adjustable brush bristle bending fixture. Background Technology

[0002] Conductive slip rings belong to the category of electrical contact sliding connections. Also known as slip rings, rotary joints, rotary electrical interfaces, conductive slip rings, current collectors, return rings, coils, commutators, and adapters, they are precision power transmission devices that enable the transmission of image, data signals, and power between two relatively rotating mechanisms. During transmission, the contact effect between the brush bristles and the conductive ring is crucial to the signal transmission performance of the conductive slip ring. Because conductive slip rings have different requirements for the span and length of the brush bristles after bending, specific bending processes are needed to manufacture brush bristles with specific spans, and the versatility of bending fixtures is poor.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figure 1-Figure 5 As shown, this utility model provides an adjustable brush bristle bending fixture, including a pad 1, two support plates 2 disposed on the pad 1, and a pressure plate 3 located between the two support plates 2. The support plates 2 are detachably connected to the pad 1, and the distance between the two support plates 2 is adjustable. The pressure plate 3 includes a first plate 7 and a second plate 8, which are movably connected. The distance between the first plate 7 and the second plate 8 is adjusted by a fixing member 11 on the side. A pressure groove is formed between the two support plates 2, and the two sides of the brush bristles are respectively limited by the two support plates 2. The pressure plate 3 presses down in the pressure groove to bend the brush bristles.

[0022] The distance between the two support plates 2 is the span after the bristles are bent. By adjusting the distance between the two support plates 2, the bending of bristles with different span requirements can be achieved. Before bending, the distance between the two support plates 2 is adjusted. During adjustment, the pad 1 is used as a base, and the two support plates 2 are moved on the pad 1 to adjust to the required span. The adjusted support plates 2 are then fixed to the pad 1. Correspondingly, the width of the pressure plate 3 also needs to be adjusted. The width of the pressure plate 3 is adjusted by adjusting the distance between plate 1 7 and plate 2 8. Then, plate 1 7 and plate 2 8 are fixed by the fastener 11 to prevent relative displacement between them. The adjusted width of the pressure plate 3 is adapted to the distance between the two support plates 2 and is slightly smaller than the distance between the two support plates 2 to ensure smooth bristle bending.

[0023] The support plate 2 is provided with slots 4 for inserting brush filaments. These slots 4 are straight, and the slots 4 on the two support plates 2 correspond one-to-one. During bending, the two sides of the brush filaments are placed into the slots 4 for positioning, ensuring the filaments are in a straight line. Then, the pressure plate 3 is aligned with the groove and pressed down, bending the brush filaments within the groove. This design features adjustable support plates 2, allowing for arbitrary adjustment within a certain range to accommodate bending of brush filaments with different span requirements. The adjustable pressure plate 3 further enhances the versatility and flexibility of the bending fixture. Multiple brush filaments can also be bent efficiently.

[0024] The pad 1 is provided with an adjustment groove 5 adapted to the width of the pad 1. The adjustment groove 5 is an oblong groove. Both support plates 2 are fixed to the pad 1 by adjusting bolts 6, which pass through the oblong groove and connect to the support plates 2. When adjusting the support plates 2, first loosen the bolts, then move the support plates 2. After moving them to a suitable distance, tighten the bolts to fix the support plates 2 to the pad 1.

[0025] The pad 1 is also provided with scale plates 18 on both sides. The scales on the scale plates 18 are symmetrically distributed in both directions, and the midpoint 19 is aligned with the midpoint of the wide side of the pad 1. The scale plates 18 can be used as a reference to accurately display the distance between the two support plates 2. The bidirectional scale of the scale plates 18 makes the reading more intuitive.

[0026] The first plate 7 has a plurality of insertion holes 10 spaced apart, and the second plate 8 has a plurality of insertion rods 9 correspondingly arranged thereon. The insertion rods 9 are inserted into the insertion holes 10, and the length of the insertion rods 9 is adapted to the length of the insertion holes 10. The insertion rods 9 are slidably connected to the insertion holes 10. The insertion rods 9 can slide within the insertion holes 10 to adjust the distance between the first plate 7 and the second plate 8. After adjustment, the first plate 7 and the second plate 8 are fixed by the fixing member 11.

[0027] The fastener 11 includes a first fixing seat 12 disposed on the first plate 7, a second fixing seat 13 disposed on the second plate 8, and a connector connecting the first fixing seat 12 and the second fixing seat 13. The first fixing seat 12 is provided with a first fixing groove 14, and the second fixing seat 13 is provided with a second fixing groove 15. The connector includes a connecting plate 16 and a connecting bolt 17 disposed on the connecting plate 16. The connecting bolt 17 passes through the first fixing groove 14 and the second fixing groove 15 respectively. Both the first fixing groove 14 and the second fixing groove 15 are elongated grooves. After adjusting the positions of the first plate 7 and the second plate 8, the connecting bolt 17 on the connecting plate 16 is inserted into the first fixing groove 14 and the second fixing groove 15 respectively, and then fixed.

[0028] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
