Description

Technical Field

[0001] This utility model relates to the field of brake manufacturing technology, specifically a machine tool for producing brakes. Background Technology

[0002] A brake is a device that functions to decelerate, stop, or maintain a stopped state of a moving part (or moving machinery). It is a mechanical component that stops or decelerates moving parts in machinery. Brakes are typically composed of metals (such as cast iron and steel) and friction materials (such as composite ceramics and semi-metals). The processing characteristics of different materials vary greatly, requiring machine tools with multi-process compatibility. Brakes require machining on production machine tools during their manufacturing process.

[0003] In brake and actuator manufacturing technologies, the raw material to be processed is clamped and then cut. During the cutting process, the tool wear status relies on manual periodic inspection, requiring frequent interruptions to the processing flow, severely restricting production efficiency. If worn tools are not replaced in time, quality problems such as workpiece dimensional deviations and surface roughness deterioration can easily occur, even leading to workpiece scrap. Furthermore, tools are usually installed with bolts, and traditional bolt-fastened tool installation methods require repeated tightening operations, which are time-consuming. In multi-process continuous processing scenarios, tool replacement time accounts for a high percentage, becoming a key obstacle to increasing production capacity. Therefore, those skilled in the art provide a machine tool for brake and actuator production to solve the problems mentioned in the background art. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] A machine tool for producing brake devices, comprising:

[0028] The processing machine tool 1 has clamping assemblies installed on both sides of its inner cavity. The clamping assemblies include an electric push rod 13, a second rotating assembly, and an arc-shaped clamping plate 14. The electric push rod 13 is fixedly installed in the inner cavity of the processing machine tool 1. The output end of the electric push rod 13 is connected to the arc-shaped clamping plate 14 through the second rotating assembly. The arc-shaped clamping plate 14 is provided with a rubber layer 15. The processing machine tool 1 is equipped with a door 2.

[0029] When clamping the raw material, the controller 22 activates the electric push rod 13. The output end of the electric push rod 13 extends and pushes the arc-shaped clamping plate 14 closer to the raw material, which can clamp the raw material. When adjusting the processing angle, the controller 22 activates the drive motor 17 in the second rotating assembly. The drive motor 17 drives the arc-shaped clamping plate 14 to rotate to a suitable angle, which can adjust the processing of the raw material.

[0030] The arc-shaped clamping plate 14 is provided with a rubber layer 15, which can protect the surface of the raw material from damage during clamping.

[0031] Servo electric cylinder 3 is fixedly installed on the upper end of the inner cavity of the machine tool 1. The output end of servo electric cylinder 3 is connected to support plate 4 through a first rotating component. Mounting plate 5 is connected to support plate 4 through an adjusting component. The adjusting component includes a second servo motor 18, a threaded rod 19 and a moving block 20. A moving groove 21 is provided on support plate 4 for the threaded rod 19 to rotate and connect. Moving block 20 is threadedly connected to threaded rod 19. Second servo motor 18 is mounted on support plate 4, and the output end of second servo motor 18 is connected to the extension end of threaded rod 19 through moving groove 21. Moving block 20 is fixedly connected to mounting plate 5. High-frequency acoustic sensor 6 is mounted on mounting plate 5.

[0032] During the cutting process, the high-frequency acoustic sensor 6 on the mounting plate 5 monitors the wear status of the cutting tool 12 in real time. When the detected signal envelope exceeds a set threshold, the system initiates a pulse width comparison. If the pulse width exceeds another threshold, it is determined that the tool is worn or damaged, and the controller 22 triggers an alarm.

[0033] The controller 22 starts the servo cylinder 3, and the output end of the servo cylinder 3 drives the support plate 4 to move up and down, which can adjust the height position of the tool.

[0034] When adjusting the horizontal position of the cutting tool 12, the controller 22 starts the drive motor 17 in the first rotating assembly. The drive motor 17 drives the support plate 4 to rotate to a suitable angle. Then the controller 22 starts the second servo motor 18. The second servo motor 18 drives the threaded rod 19 to rotate in the moving groove 21. Since the moving block 20 is threadedly connected to the threaded rod 19, the moving block 20 will move along the threaded rod 19, thereby driving the mounting plate 5 and the components mounted on it to move horizontally.

[0035] A water tank 7 is installed on the support plate 4, and a nozzle 8 is installed on the mounting plate 5. The nozzle 8 is connected to the water tank 7 through a connecting assembly, which includes a water pump 23, a water suction pipe 24, and a connecting pipe 25. The water pump 23 is fixedly installed on the water tank 7. One end of the water suction pipe 24 is connected to the water pump 23, and the other end of the water suction pipe 24 passes through the water tank 7. One end of the connecting pipe 25 is connected to the water pump 23, and the other end of the connecting pipe 25 is connected to the nozzle 8.

[0036] The controller 22 starts the water pump 23, which draws the coolant from the water tank 7 through the water pipe 24 and then delivers it to the nozzle 8 through the connecting pipe 25. The coolant is sprayed out from the nozzle 8 to cool and lubricate the processing part.

[0037] Furthermore, the water tank 7 is equipped with a water inlet pipe 26, and a baffle 27 is threaded onto the water inlet pipe 26. When adding cutting fluid to the water tank 7, the baffle 27 is opened, and the cutting fluid is added into the water tank 7 through the water inlet pipe 26.

[0038] In the above embodiments, both the first rotating assembly and the second rotating assembly include a mounting frame 16 and a drive motor 17. The mounting frame 16 is connected to the output ends of the servo cylinder 3 and the electric push rod 13, respectively. The drive motor 17 is installed inside the mounting frame 16, and the output ends of the drive motor 17 are connected to the support plate 4 and the arc-shaped clamping plate 14, respectively. A controller 22 is installed on the door 2. The controller 22 is electrically connected to the servo cylinder 3, the high-frequency acoustic sensor 6, the first servo motor 9, the electric push rod 13, the drive motor 17, the second servo motor 18, and the water pump 23, respectively.

[0039] A first servo motor 9 is fixedly mounted on the mounting plate 5. The output end of the first servo motor 9 is connected to a rotating rod 10. The rotating rod 10 is connected to a connecting rod 11 through a locking mechanism. The locking mechanism includes a connecting ring 28, a retaining ring 29, a fixing ring 30, a return spring 31, and a limiting bead 32. The connecting ring 28 and the retaining ring 29 are respectively connected to the connecting rod 11 and the rotating rod 10. One end of the rotating rod 10 is locked in the connecting ring 28. The connecting ring 28 has several arc-shaped grooves 33. The limiting bead 32 is rotatably connected in the arc-shaped grooves 33. The rotating rod 10 has a locking groove 34 for the limiting bead 32 to lock in. The connecting ring 28 is locked in the retaining ring 29. The fixing ring 30 is fixedly connected to the rotating rod 10. The return spring 31 is connected between the retaining ring 29 and the fixing ring 30. The other end of the connecting rod 11 is provided with a cutting blade 12.

[0040] When installing the cutting tool 12, insert one end of the rotating rod 10 into the connecting ring 28, then release the retaining ring 29, the return spring 31 releases its elastic potential energy, pushes the retaining ring 29, and the retaining ring 29 contacts and connects with the limiting bead 32, so that the limiting bead 32 is inserted into the engaging groove 34 on the rotating rod 10, thus completing the installation of the connecting rod 11 and the cutting tool 12.

[0041] When disassembling the cutting tool 12, pull the retaining ring 29, then pull the connecting rod 11. The limiting bead 32 rotates in the arc groove 33 and moves out of the engaging groove 34. Then the rotating rod 10 moves out of the connecting ring 28.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
