Description

Technical Field

[0001] The present application relates to the technical field of auxiliary clamps, and in particular to a brake disc clamp that is easy to support with a change of shape. Background Art

[0002] The brake disc, in simple terms, is a round plate. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc is characterized by thin walls, and the disc and the center are formed by sand cores. Different types of brake discs have differences in disc diameter, disc thickness, and the gap between the two discs. The thickness and height of the disc hub are also different. Therefore, after the brake disc is processed, a dynamic balance test is required.

[0003] Before performing a dynamic balance test, the brake disc needs to be fixed by a clamp. The prior art discloses a dynamic balance detection clamp for automobile brake discs, including a driving mechanism; a guide disc is also installed above the driving mechanism, and a transmission mechanism is also meshed and transmitted on the outside of the driving mechanism, and a limiting mechanism is also arranged on the upper side of the transmission mechanism. The limiting mechanism includes a lifting component, the main body of the lifting component is designed as an arc block structure, and a guide bead is also arranged on the top of the lifting component, and a spring is also arranged on the lower side of the lifting component. The driving mechanism includes: a driving component, the main body of the driving component is a motor, a transmission shaft is also installed on the upper side of the motor, and a bevel gear is sleeved on the outer side of the transmission shaft.

[0004] With respect to the above-mentioned related technologies, the brake disc is clamped and fixed by multiple clamping assemblies that slide radially along the guide disc. This means that the maximum diameter of the brake disc that can be used by the clamp in the prior art cannot exceed the diameter of the guide disc. In fact, the diameter of the brake disc varies greatly depending on the type of vehicle the brake disc is used in, and the clamp in the prior art has a relatively small range of applicability for the spacing between brake discs of different diameters.

[0039] The following is combined with Figure 1-3 This application is described in further detail.

[0040] The embodiment of the present application discloses a brake disc clamp that is easy to support with a changed shape.

[0041] Example 1

[0042] Reference Figure 1A brake disc clamp that is easy to support by changing shape includes a mounting disc 1, a movable bar 2 and a clamping unit 5. The number of movable bars 2 is multiple, and the movable bar 2 is located above the mounting disc 1. One end of the movable bar 2 is movably connected to the mounting disc 1. The clamping unit 5 is installed on the mounting disc 1, and the clamping unit 5 is arranged through the center hole of the brake disc and can be tightly pressed against the center hole wall of the brake disc; in the present application, the number of movable bars 2 can be three, four, or five, as long as a stable supporting surface can be formed. The clamping unit 5 can be set as an expansion sleeve, and can also be set as other structures that can expand outward to clamp the brake disc. In the present embodiment, the number of movable bars 2 is four, and the clamping unit 5 is set as an expansion sleeve.

[0043] Reference Figure 1 and Figure 2 The other end of the moving bar 2 is connected to a support block 3, and the top walls of multiple support blocks 3 are in the same plane to form a support surface in contact with the brake disc. When force is applied to the moving bar 2 to change the relative position of the moving bar 2 and the mounting disc 1, the distance between the axis of the support block 3 and the mounting disc 1 changes accordingly; in order to facilitate the replacement of the support block 3, the support block 3 and the moving bar 2 are detachably fixedly connected, which can be achieved by plugging in or by countersunk bolts.

[0044] Reference Figure 1 and Figure 2 , a sliding block 6 is bolted to the moving bar 2, and a plurality of guide grooves 11 for the sliding of the sliding block 6 are provided on the mounting plate 1. In the present application, the number of the guide grooves 11 is consistent with the number of the moving bars 2, and the width of the guide grooves 11 is smaller than the width of the moving bar 2. In the present application, the guide grooves 11 can be provided along the radial direction of the mounting plate 1, can be provided along the involute direction, and can also be provided along the tangential direction parallel to the mounting plate 1. In the present embodiment, in order to expand the adjustment range of the support block 3 as much as possible under the condition of limited size of the mounting plate 1, the guide grooves 11 are provided along the tangential direction parallel to the mounting plate 1.

[0045] Reference Figure 1 and Figure 2 In order to facilitate the quick and easy reading of real-time extension data during the movement of the moving bar 2, a scale bar 7 is engraved on the mounting plate 1 along the opening direction of the guide slot 11, and an indicator arrow 8 is engraved on the moving bar 2. The extension data can be quickly read by the cooperation of the indicator arrow 8 and the scale bar 7.

[0046] Reference Figure 1 and Figure 2In order to fix the position of the moving bar 2 after the moving bar 2 moves into place, the brake disc clamp for facilitating the change of support also includes a plurality of fixing units 4. The number of fixing units 4 in the present application is consistent with the number of the moving bar 2. The fixing units 4 are connected to the moving bar 2, and the fixing units 4 are connected to the mounting plate 1, so as to keep the mounting plate 1 and the moving bar 2 relatively still.

[0047] Reference Figure 1 and Figure 2 The fixing unit 4 includes a first fixing bolt 41, a screw section of the first fixing bolt 41 is set through the moving bar 2, and the first fixing bolt 41 is slidably connected to the moving bar 2, and a plurality of first locking holes 12 are opened on the mounting plate 1, and the plurality of first locking holes 12 are distributed along the opening direction of the guide slide groove 11, and the first fixing bolt 41 can extend into the first locking hole 12 and be threadedly connected to the mounting plate 1; through the cooperation of the first fixing bolt 41 and the plurality of first locking holes 12, the position of the moving bar 2 can be fixed after adjusting the distance between the support block 3 and the axis of the mounting plate 1.

[0048] Reference Figure 1 In order to reduce the interference of the nut section of the first fixing screw with the brake disc support surface, a nut cavity 21 is opened on the movable bar 2, and the nut section of the first fixing bolt 41 is located in the accommodating cavity.

[0049] The implementation principle of a brake disc clamp that is easy to change support in Example 1 of the present application is: force is applied to the movable bar 2, and the movable bar 2 applies force to the sliding block 6 so that the sliding block 6 slides along the opening direction of the guide groove 11. The movable bar 2 slides and drives the support block 3 to move in a direction away from the axis of the mounting plate 1. While sliding, observe the correspondence between the indicator arrow 8 and the scale bar 7 until the support block 3 moves into place, and then fix the movable bar 2 by the first fixing bolt 41, and then place the brake disc on the support surface, and then fix the brake disc by the expansion sleeve, and start the dynamic balance test.

[0050] Example 2

[0052] The implementation principle of the brake disc clamp for easy support change in Example 2 of the present application is: force is applied to the movable bar 2, and the movable bar 2 rotates around the rotation axis while driving the support block 3 to move until the support block 3 moves into place, and then the movable bar 2 is fixed by the second fixing bolt 42, and then the brake disc is placed on the support surface, and then the brake disc is fixed by the expansion sleeve, and the dynamic balance test can be started.
