Description

Technical Field

[0001] This utility model relates to the field of fastener manufacturing, and in particular to a testing device for bicycle disc brake components. Background Technology

[0002] Disc brakes are a widely used type of brake for bicycles. They work by using a built-in disc brake mechanism that applies pressure to one side of the disc to slow the vehicle down. This built-in mechanism is a crucial part of the disc brake's operation; a smooth, stable, and powerful action ensures effective braking.

[0003] like Figure 5 and Figure 6 The bicycle disc brake component shown includes a screw, a nut, and several balls. Both the nut and screw have multiple ball-receiving grooves arranged in a circular array. During operation, one end of the ball is housed in a groove in the nut, while the other end is housed in a groove in the screw. The balls can roll between adjacent grooves. Due to product requirements, the ball-receiving grooves require high dimensional accuracy. If the dimensions of the ball-receiving grooves on the nut do not conform to the standard, the rolling of the balls between adjacent grooves will be hindered, resulting in a defective product. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for bicycle disc brake components, which simulates the working state of a nut and tests the dimensions of the ball bearing groove on the nut.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bicycle disc brake component testing device, comprising:

[0006] The base has a circular groove on its lower surface and a plurality of sliding grooves evenly spaced around the positioning rod on its upper surface, with the lower end of each sliding groove connected to the circular groove.

[0007] An outer sleeve, wherein the outer sleeve is fitted inside a circular groove;

[0008] Inner sleeve, which is fitted inside the outer sleeve;

[0009] A positioning rod, the lower end of which is fitted inside the inner sleeve, and the upper end of which penetrates the base;

[0010] A plurality of detection components are evenly spaced around a positioning rod, each detection component corresponding to a sliding groove. Each detection component includes a column and a detection block, which are connected sequentially from bottom to top. The upper end of the column slides radially within the sliding groove along the positioning rod, and the lower end of the column is clamped between the inner wall of the outer sleeve and the outer wall of the inner sleeve. By disassembling and replacing outer sleeves and inner sleeves with different inner diameters, the positions of each detection component can be changed, allowing for flexible detection of nuts of multiple sizes. The detection components can be replaced according to the size of the ball bearing groove on the nut, offering flexibility and versatility.

[0011] Preferably, a central hole is provided at the center of the upper surface of the base, and the end of each slide near the positioning rod is connected to the central hole, with the upper end of the positioning rod passing through the central hole.

[0012] Preferably, the cross-section of the column is fan-shaped, and the two ends of the column are rounded.

[0013] Preferably, the upper surface of the column is coplanar with the upper surface of the base. The lower end of the detection block is flush with the upper surface of the base. During detection, when the nut is in its lowest position, its lower surface is in contact with the upper surface of the base.

[0014] Preferably, the upper surface of the base is provided with at least three evenly spaced grooves around the positioning rod.

[0015] Preferably, the inner sleeve is a barrel structure with an open top, and the edge of the upper surface of the inner sleeve is chamfered.

[0016] Preferably, the outer sleeve is a barrel structure with an open top, the edge of the upper surface of the outer sleeve is chamfered, and the height of the outer sleeve is greater than or equal to the depth of the circular groove.

[0017] Preferably, the detection block is a spherical cap structure, and the detection block is disposed at one end of the upper surface of the column.

[0018] Preferably, the detection block includes a front end and an end end, the front end and the end end of the detection block surround the positioning rod and are connected sequentially in a clockwise direction, and the longitudinal section of the end end of the detection block gradually decreases in a clockwise direction.

[0019] Preferably, the positioning rod is detachably connected to the inner sleeve.

[0020] The beneficial effects of this invention are as follows: During use, the positioning rod penetrates the nut to locate its position and detects the diameter of the nut's threaded hole. The detection block is located inside the ball bearing groove of the nut. When the nut is manually rotated, the detection block will shift relative to the ball bearing groove on the nut. The detection block will sequentially move through each ball bearing groove, and the vertical movement distance of the nut can be observed manually to detect the size of the ball bearing groove on the nut.

[0021] By disassembling and replacing outer sleeves with different inner diameters and inner sleeves with different outer diameters, the positions of each detection component can be changed, allowing for flexible detection of nuts of multiple specifications. Attached Figure Description
