Description

Technical Field

[0001] This utility model relates to the field of traction machine technology, specifically to a quick clamping and break-in device for friction blocks of traction machine brakes. Background Technology

[0002] The existing traction machine brake friction plate break-in process involves pre-grinding each friction plate to the required arc shape, then assembling them one by one onto a fixed block, and finally assembling them onto the brake armature. This break-in followed by assembly introduces certain assembly errors, which may result in the friction plate and armature surface not being parallel after assembly. This leads to insufficient contact between the brake friction plate and the traction sheave when mounted on the traction machine, affecting the brake air gap. It also results in insufficient friction area, affecting the braking effect.

[0003] To optimize the break-in process, it is necessary to develop dedicated friction plate break-in equipment. In the prior art, such as the utility model patent with application number CN201621190341.0 and invention title: "A Friction Plate Break-in Device for Traction Machine Brake", a solution is provided that uses a brake arm to cooperate with the friction plate to approach the traction machine brake wheel for friction break-in.

[0004] However, the friction between the friction plate and the traction machine brake wheel is large when rotating at high speed, and the brake arm is prone to vibration. If the operator is not stable, it is very easy to cause danger.

[0005] To reduce the risks, these break-in equipment need to be upgraded and modified to improve operational safety and convenience. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a traction machine brake friction block quick clamping and break-in device that offers higher safety and greater ease of operation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a quick clamping and running-in device for friction blocks of a traction machine brake, including a running-in machine, wherein the running-in window of the running-in machine is located at the top, and a tooling base plate is provided at the running-in window of the running-in machine.

[0008] A friction block embedding frame is provided on the tooling base plate corresponding to the running-in window, and the outline of the friction block embedding frame is consistent with the outer outline of the friction block assembly.

[0009] The tooling base plate is provided with several positioning pins and at least one pair of springs around the running-in window. The positioning pins are used to cooperate with the positioning holes on the friction block assembly, and the springs are used to support the friction block assembly. The springs, positioning pins and friction block assembly cooperate to enable the friction block assembly to move vertically over a short distance.

[0010] Two sets of movable clamping mechanisms are respectively provided at both ends of the tooling base plate corresponding to the running-in window, which are used to clamp the friction block assembly from top to bottom.

[0011] Preferably, the tooling base plate is fixed to the top of the running-in machine by bolts.

[0012] Preferably, the positioning pins are cylindrical and distributed at the four corners of the friction block embedding frame.

[0014] Preferably, the movable clamping mechanism includes a mounting base, a handle, and a movable pressure head. The bottom end of the handle and the bottom end of the movable pressure head are both hinged to the mounting base. The bottom end of the handle is provided with a crank portion, which is hinged to the non-hinged point of the movable pressure head. When the handle swings outward, the crank portion drives the movable pressure head to swing inward until it clamps the top of the friction block assembly.

[0015] Preferably, the bottom end of the handle is hinged to the mounting base via a hinge.

[0016] Preferably, the movable pressing mechanism includes a mounting plate and a swing arm hinged to the mounting plate. The outer end of the swing arm is an operating handle and the inner end is a movable pressure head. By raising the operating handle, the movable pressure head is pressed against the top of the friction block assembly.

[0017] Preferably, the mounting base is fixed to the tooling base plate by adjusting bolts to adjust the height of the mounting base.

[0018] Preferably, the running-in machine includes a base, a support frame, a drive motor, a rotor, a pulley assembly, and a sanding belt. The drive motor is installed in the support frame, the base is fixed to the top of the support frame, the rotor is installed on the base, the drive motor drives the pulley assembly to rotate the rotor, the sanding belt is disposed on the surface of the rotor, and the rotor drives the sanding belt to rotate and pass through the running-in window at the top.

[0019] Preferably, the friction block embedding frame of the tooling base plate is a rectangular frame.

[0020] This utility model has substantial features and advancements compared to existing technologies. Specifically, this utility model sets a running-in window at the top of the running-in machine and sets a tooling base plate. Based on the tooling base plate, a positioning pin, a spring, and a movable clamping mechanism are set. The friction block assembly is installed into the embedded frame of the tooling base plate, which can be raised and lowered within a short distance. Then, the movable clamping mechanism is used to slowly press down the friction block assembly to achieve uniform running-in of the friction block assembly, avoiding manual intervention. Since the operator does not directly operate the friction block assembly, safety is guaranteed, and efficiency is relatively higher. Attached Figure Description

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0028] like Figures 1-5 As shown, a quick clamping and running-in device for friction blocks of a traction machine brake includes a running-in machine, with a running-in window located at the top of the running-in machine. A tooling base plate 100 is provided at the running-in window of the running-in machine, and the tooling base plate 100 is fixed to the top of the running-in machine by bolts.

[0029] A friction block embedding frame 101 is provided on the tooling base plate 100 corresponding to the running-in window. The outline of the friction block embedding frame 101 is consistent with the outer outline of the friction block assembly 200. In this embodiment, the friction block embedding frame 101 of the tooling base plate is a rectangular frame.

[0030] In this embodiment, the friction block assembly 200 is an assembly structure consisting of an armature and a friction block. The armature is used to support the friction block and facilitates cooperation with other structures.

[0031] In this embodiment, the running-in machine mainly includes a base 300, a support frame 301, a drive motor 302, a rotor 303, a pulley 304, a belt 305, and a sanding belt 306. The drive motor 302 is installed in the support frame 301, and the base 300 is fixed to the top of the support frame 301. The rotor 303 is installed on the base 300. The drive motor 302 drives the pulley 306 and the belt 305 to drive the rotor 303 to rotate. The sanding belt 306 is disposed on the surface of the rotor 303. The rotor 303 drives the sanding belt 306 to rotate and pass through the running-in window at the top.

[0032] The tooling base plate 100 is provided with several positioning pins 102 and at least one pair of springs 103 around the running-in window. The positioning pins 102 are used to cooperate with the positioning holes on the friction block assembly 200. Specifically, the positioning holes are set on the armature. The springs 103 are used to support the friction block assembly 200. The springs 103, positioning pins 102 and friction block assembly 200 cooperate to enable the friction block assembly 200 to move vertically over a short distance.

[0033] The positioning pins 102 are cylindrical and four are arranged around the friction block embedding frame 101 at the four corners. The positioning pins 102 play a vertical guiding role. The springs 103 are installed in pairs on the upper surface of the tooling base plate 100 at both ends of the friction block embedding frame 101. The springs 103 play a role in resetting and springing up.

[0034] Two sets of movable clamping mechanisms 104 are respectively provided on the tooling base plate 100 at both ends corresponding to the running-in window, for clamping the friction block assembly 200 from top to bottom.

[0035] In this embodiment, the movable pressing mechanism 104 includes a mounting base 1041, a handle 1042, and a movable pressing head 1043. The bottom ends of the handle 1042 and the movable pressing head 1043 are both hinged to the mounting base 1041. The bottom end of the handle 1042 is provided with a crank portion 1044, which is hinged to the non-hinged point of the movable pressing head 1043. When the handle 1042 swings outward, the crank portion 1044 drives the movable pressing head 1043 to swing inward until it presses the top of the friction block assembly 200.

[0036] In order to make the range of motion of the handle 1042 large enough, the bottom end of the handle 1042 is hinged to the mounting base 1041 via a hinge 1045.

[0037] To meet the friction requirements of friction plates of different thicknesses, the mounting base 1041 is fixed to the tooling base plate 100 by adjusting bolts 1046 to adjust the height of the mounting base 1041, so as to achieve constant curvature and running-in of workpieces of various thicknesses.

[0038] In other embodiments, another movable clamping mechanism is provided, which includes a mounting plate and a swing arm hinged to the mounting plate. The outer end of the swing arm is an operating handle, the inner end is a movable pressure head, and the middle part is hinged to the mounting plate. By raising the operating handle, the movable pressure head is pressed against the top of the friction block assembly, forming the simplest lever structure.

[0039] Working principle explanation:

[0040] First, adjust the overall height of the movable clamping mechanism 104 according to the size of the friction block assembly to be processed.

[0041] Then, the friction block assembly 200 is installed into the friction block embedding frame 101 of the tooling base plate 100. The positioning hole of the armature part of the friction block assembly 200 is engaged with the positioning pin 102, and the lower end face of the armature part is pressed on the spring.

[0042] Start the running-in machine, drive the motor 302 to drive the sanding belt 306 to rotate, pass through the running-in window, operate the handle 1042 of the movable pressing mechanism 104 to press down the movable pressure head 1043, and press down and move the friction block assembly 200 as a whole until the surface of the friction block at the bottom end contacts the surface of the sanding belt.

[0043] When you hear the sound of the yarn belt breaking in with the friction block, pause for 1-2 seconds and press the movable pressure head 1043 all the way down. As the friction block assembly wears down, it will continue until the bottom surface of the armature of the friction block contacts the tool base plate 100. Once the breaking-in dimensions are in place, lift the handle, the movable pressure head 1043 will return to its original position, and the spring will lift the friction block assembly, completing the breaking-in process.

[0044] When the work is completed, turn off the power and the drive motor will stop rotating.

[0045] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
