Description

Technical Field

[0001] The present invention relates to the technical field of brake clamping force detection, and more specifically, to a brake clamping force detection device. Background Art

[0002] The brake is a mechanical deceleration part that slows down or stops mechanical movement. The main braking function of the common brake is to generate braking friction through friction, thereby achieving the braking effect. The external driving force of the friction brake is mechanically transmitted to the friction plate, so that extrusion is generated between the friction plate and the brake disc, and then friction is generated between the brake disc and the friction plate through extrusion. This friction force causes the brake disc to slow down or stop rotating, thereby achieving the braking effect.

[0003] After the existing brakes are produced, the braking effect of the brakes needs to be tested. The main test indicator is the clamping force of the brakes. However, the structural sizes of existing brakes are diverse, and the sizes of compatible brake discs are also different. The existing brake detection devices are usually adapted to a single specification of brakes for clamping force detection, and cannot be adjusted to adapt to the clamping force detection of brakes of different sizes, so structural optimization is needed.

[0034] The tops of the two groups of first support frames 2 also support a synchronous adjustment mechanism, which is used to drive the support slider 4 to move, thereby adjusting the distance between the detection installation mechanism and the test mechanism. The synchronous adjustment mechanism includes an adjustment disk 9 arranged on the outside of the second transmission shaft 13, and limit grooves 12 are arranged at the edge positions on both sides of the adjustment disk 9.

When the detection disk 11 rotates, the driven gear 20 is driven to rotate and mesh with the driving gear 25. When the brake body 7 follows the mounting disk 8 to rotate to correspond to the brake disc body 10, the brake body 7 is clamped on both sides of the brake disc body 10. A power unit for providing a braking driving force for the brake body 7 is arranged on the outer side of the mounting disk 8. The power unit is used to drive the brake body 7 to clamp the brake disc body 10. A driving motor 18 is arranged on one end of the back side of the top of the mounting base 1, and a tensioning mechanism 29 is arranged at the top of the mounting base 1 near the driving motor 18. A transmission belt 27 is arranged on the output end of the driving motor 18 and the tensioning mechanism 29, the toggle disk 15, and the outer side of the central shaft 26. The driving motor 18 is used to drive the toggle disk 15 and the driving gear 25 to rotate.

[0037] The use process of the brake clamping force detection device proposed in this embodiment is as follows: when the clamping force of the brake body 7 needs to be detected, the second transmission shaft 13 is adjusted and rotated, thereby driving the adjustment disk 9 and the detection disk 11 to rotate;

[0038] The rotation of the adjusting disk 9 drives the limiting groove 12 to rotate accordingly. At this time, the adjusting rod 3 engaged with the limiting groove 12 is driven by the driving force of the groove and the convex groove of the limiting groove 12, so that the adjusting rod 3 pushes the supporting slider 4 to follow the displacement, thereby driving the brake body 7 on the top of the supporting slider 4 to follow the displacement;

[0039] The detection disc 11 rotates to drive the brake disc body 10 and the driven gear 20 at one end of the mounting frame 24 to rotate accordingly, and the brake disc body 10 for testing is adjusted to a position corresponding to the brake body 7. At this time, the driven gear 20 rotates accordingly to a state of mutual meshing with the driving gear 25.

[0040] After the brake disc body 10 is adjusted to the detection position, one end of the adjusting rod 3 is engaged with the groove corresponding to the limiting groove 12, and at the same time, the supporting slider 4 is acted upon by the elastic force of the return spring 22, so that the supporting slider 4 drives the adjusting rod 3 to be squeezed toward the limiting groove 12, thereby positioning the adjusting disc 9;

[0041] In the process of adjusting the corresponding positions of the brake disc body 10 and the brake body 7, the transmission belt 27 is extended and displaced by the displacement power of the support slider 4, and then the tensioning force is automatically adapted and adjusted through the tensioning mechanism 29. The tensioning mechanism 29 is any belt tensioning adjustment structure in the prior art, and will not be described in detail here;

[0042] Further, the driving motor 18 is started to drive the transmission belt 27 to rotate, thereby driving the toggle plate 15 and the driving gear 25 to rotate, and the rotation of the toggle plate 15 drives the cylindrical pin 28 to intermittently engage with the groove wheel 14, thereby driving the groove wheel 14 to intermittently rotate, and the groove wheel 14 drives the installation plate 8 on the outer side of the first transmission shaft 6 to intermittently rotate, so that a plurality of groups of brake bodies 7 installed on the outer side of the installation plate 8 are intermittently adapted to the brake disc body 10, so as to detect the clamping force;

[0043] The rotation of the driving gear 25 drives the driven gear 20 to rotate, thereby driving the brake disc body 10 to rotate, so that the brake disc body 10 is in a state of rotation, simulating the detection state of the clamping force of the brake disc body 10 by the brake body 7 in the state of rotation, which is more in line with the actual working state and improves the accuracy of the detection result;

[0044] When the brake body 7 completes the detection of the brake disc body 10 of the same specification, the second transmission shaft 13 can be rotated again to adjust another set of brake disc bodies 10 of different specifications and sizes for detecting the brake body 7. Due to the different specifications and sizes, the sizes of the clamping surfaces of the brake body 7 and the brake disc body 10 are also different, the clamping force states generated are also different, and the braking effects are also different. Then, the clamping force states of the brake body 7 to the brake disc bodies 10 of different specifications and sizes are tested, thereby improving the diversity of the detection results.

[0045] The clamping force is converted into an electrical signal by a pressure sensor on the outside of the brake disc body 10 and transmitted to the control unit for storage and display, thereby facilitating observation by inspection personnel.

[0046] The specific implementation methods of this embodiment are described above, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms inspired by this embodiment, all of which are within the protection of this embodiment.
