Description

Technical Field

[0001] The utility model relates to the technical field of elevator traction machines, in particular to a fast-adhesion and clamping device for a brake disc friction plate of a traction machine disc brake. Background Art

[0002] The traction machine brake is a key safety component in the entire traction machine. Currently, the commonly used traction machine brakes are divided into plate brakes and disc brakes. For disc brakes, the overall safety of the brake disc is the key point of the safety of the entire brake.

[0003] The friction pad of the brake disc usually causes two problems during assembly:

[0004] The first problem is that the friction plate is installed on the brake disc by bonding, but in the prior art, the tooling pressure cannot be effectively controlled during bonding, resulting in uneven distribution of the adhesive. There is a risk of breakage, falling off, and falling off during later use.

[0005] The second problem is that after the friction plate is installed, the thickness of the brake disc may be inconsistent due to uneven distribution of the adhesive and uneven distribution of tooling pressure, posing a risk of brake slip.

[0006] In order to solve the above two problems, people continue to design a new method for manufacturing brake discs. Utility Model Content

[0007] The utility model aims to address the deficiencies of the prior art and thus provide a traction machine disc brake friction plate bonding and fast pressing device with controllable pressure distribution, quick disassembly and uniform adhesive distribution.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a traction machine disc brake friction plate bonding fast pressing device, including a base, a locking shaft, a locking nut, and an elastic distributed pressure plate;

[0009] The base is provided with a brake disc friction plate assembly platform, the bottom end of the locking shaft is fixed at the center of the base, the upper part of the locking shaft is provided with a thread, and the locking nut is matched with the upper thread of the locking shaft;

[0010] The lower disk surface of the elastic distributed pressure disk serves as a clamping surface. The elastic distributed pressure disk is provided with a central guide hole restricted by a locking shaft. The locking nut exerts force on the elastic distributed pressure disk by cooperating with the locking shaft. The elastic distributed pressure disk cooperates with the brake disc friction plate assembly platform to form a clamping mechanism.

[0011] Based on the above, the elastic distributed pressure plate includes a top plate, a floating pressure plate, a guide column, an adjusting nut and a spring. The guide columns are evenly distributed along the circumference and fixed on the floating pressure plate. The corresponding positions of the top plate are provided with guide holes corresponding to the guide columns. The spring is sleeved on the guide columns and is located between the top plate and the floating pressure plate for transmitting force. The top end of the guide column is provided with a threaded section, and the adjusting nut cooperates with the threaded section of the guide column.

[0012] A central guide hole corresponding to the locking shaft is arranged at the center of the top plate.

[0013] Based on the above, the floating pressure plate is a plurality of independent plates spliced ​​into a circular ring shape.

[0014] Based on the above, at least two guide posts are arranged on each independent plate, and the installation positions of the guide posts are evenly distributed relative to the size of a single independent plate.

[0015] Based on the above, the locking nut is pressed against the top plate via a flat washer.

[0016] Based on the above, a positioning step is provided at the brake disc friction plate assembly platform on the base.

[0017] Based on the above, the upper section of the locking shaft is provided with scale markings.

[0018] Based on the above, the floating pressure plate includes three to five independent plates.

[0019] Based on the above, the diameter of the locking shaft is larger than the diameter of each guide column.

[0020] Based on the above, the outer contours of the top plate and the floating pressure plate are both standard circles.

[0021] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0022] 1. The entire clamping device uses a top elastic distributed pressure plate for flexible pressure application, and the bottom assembly platform provides a flatness foundation, so that the applied pressure can be evenly distributed through the flexible elastic distributed pressure plate, ensuring the uniformity of the applied force, and the size of the pressure is controllable and adjustable, thereby ensuring that the adhesive between the brake disc and the friction plate is evenly distributed, the pressure is evenly distributed, and the thickness consistency of the overall product is high.

[0023] 2. The structure of the elastic distributed pressure plate is composed of a top plate, a guide shaft, a spring and a floating pressure plate. The pressure on the top plate is transmitted to the floating pressure plate through the spring. The movement of the floating pressure plate is constrained by the guide shaft, so that the force transmitted by the top plate can be flexibly and evenly distributed.

[0024] 3. The floating pressure plate is designed as a split structure composed of multiple plates, which can solve the problem that the friction force of the overall pressure plate is uneven due to the flatness problem, which in turn causes uneven distribution of adhesive.

[0030] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0031] like Figure 1-Figure 4 As shown, a traction machine disc brake friction plate bonding and fast pressing device comprises a base 1, a locking shaft 10, a locking nut 9, and an elastic distributed pressure plate.

[0032] The base 1 is provided with a brake disc friction plate assembly platform, and a positioning step can be provided on the brake disc friction plate assembly platform to limit the orientation of the friction plate 11 placed thereon.

[0033] The bottom end of the locking shaft 10 is fixed at the center of the base 1, and a thread is arranged on the upper part of the locking shaft 10. The locking nut 9 cooperates with the upper thread of the locking shaft 10 to form a force-applying mechanism. By adjusting the height of the locking nut 9, force can be applied downward to the elastic distributed pressure plate.

[0034] In a preferred embodiment, the locking nut 9 presses the top plate 5 of the elastic distributed pressure plate through the flat washer 8, so as to make the force distribution more uniform by expanding the force application area.

[0035] The lower disk surface of the elastic distributed pressure disk serves as a pressing surface for pressing on the friction plate 11 on the upper side of the brake disk 2 .

[0036] The elastic distributed pressure plate is provided with a central guide hole 12 restricted by the locking shaft. The locking nut 9 applies force to the elastic distributed pressure plate by cooperating with the locking shaft 10. The elastic distributed pressure plate cooperates with the brake disc friction plate assembly platform to form a clamping mechanism.

[0037] Specifically, in this embodiment, the elastic distributed pressure plate includes a top plate 5, a floating pressure plate 3, a guide column 6, an adjustment nut 7 and a spring 4. The outer contours of the top plate 5 and the floating pressure plate 3 are both standard circles.

[0038] The guide posts 6 are evenly distributed along the circumference and fixed on the floating pressure plate 3. The corresponding positions of the top plate 5 are provided with guide holes corresponding to the guide posts 6. The spring 4 is sleeved on the guide posts 6 and is located between the top plate 5 and the floating pressure plate 3 for transmitting force. The top end of the guide posts 6 is provided with a threaded section, and the adjusting nut 7 cooperates with the threaded section of the guide posts 6.

[0039] The center of the top plate 5 is provided with the aforementioned center guide hole 12 corresponding to the locking shaft 10 .

[0040] The diameter of the locking shaft 10 is larger than the diameter of each guide column 6, so that the force distribution at the force application end is more balanced and stable.

[0041] In a preferred embodiment, the floating pressure plate 3 is a plurality of independent plates spliced ​​into a circular ring, such as a structure of four independent plates as shown in the figure, and two symmetrical guide columns 6 are installed in each independent plate structure.

[0042] In other embodiments, the number of guide posts on the independent plate can be adapted according to the size of the independent plate.

[0043] In order to achieve accurate adjustment, the upper section of the locking shaft 10 is provided with scale marks. In the brake pad assembly process based on the same batch of brake discs, by setting a unified scale mark, the pressure applied by the batch is made uniform.

[0044] Technical principle description:

[0045] When in use, the elastic distributed pressure plate is first assembled in place to ensure that the top plate 5 and the floating pressure plate 3 are parallel to each other so that the subsequent force transmission is balanced.

[0046] Place a friction plate 11 on the base 1, then place the brake disc 2 coated with adhesive on both sides flat on the lower friction plate 11, and then place another friction plate on the upper surface of the brake disc 2 to complete the placement of the workpieces.

[0047] Then, the elastic distributed pressure plate is sleeved on the locking shaft 10 through the central guide hole 12, the lower surface of the floating pressure plate 3 is pressed on the upper end surface of the upper friction plate 11, the locking nut 9 is installed, and pressure is started.

[0048] As the locking nut 9 is screwed, the elastic distributed pressure plate is driven downward, and the floating pressure plate 3 applies full pressure to the brake disc and the friction pad.

[0049] Due to the split design of the floating pressure plate 3, the problem of uneven force application due to the lack of flatness of the overall structure of the floating pressure plate 3 is avoided, and the consistency of the thickness distribution of the brake disc is ensured.

[0050] The scale is used to help determine the downward displacement, and the position is fixed each time the nut is tightened, ensuring consistency in the spring force during the bonding process of batch products.

[0051] The device can be quickly disassembled and assembled, is easy to use, and the tooling can be assembled in advance before bonding, which can increase the bonding speed between the brake disc and the friction pad.

[0052] The block-type floating pressure plate + spring device has a consistent production process, which ensures the consistency of finished product thickness and reduces the subsequent brake disc thickness processing.

[0053] The positioning step and guide shaft device can ensure the verticality of the force, and the pressure can be effectively transmitted to the brake disc and friction plate to ensure uniform force.

[0054] Finally, it should be noted that: The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
