Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, specifically to a pneumatic braking device for a linear rotary motor. Background Technology

[0002] In modern industrial automated production, linear rotary motors are widely used in various precision mechanical equipment due to their efficient power transmission and precise motion control. The braking device, as a key component for the safe and stable operation of linear rotary motors, directly affects the overall operating efficiency and safety of the equipment.

[0003] Traditional linear rotary motor braking devices have revealed numerous problems in practical applications. For example, common brake structure designs result in a relatively large distance between the brake pads and the supporting mechanism. This necessitates overcoming a significant spatial distance to achieve braking, thus weakening the braking force and response speed. Furthermore, the traditional drive method's method of pushing the brake pads into contact with the supporting mechanism is not rapid enough, further reducing braking effectiveness. In applications with extremely high braking timeliness requirements, such as high-speed automated production lines or precision machining equipment, this deficiency can lead to serious production accidents, causing equipment damage and production stoppages.

[0004] Furthermore, the greater distance between the brake pads and the load-bearing structure leads to unnecessary energy loss during braking, reducing energy efficiency. At the same time, the larger braking space requirement limits the miniaturization and compact design of the equipment, increasing its overall size and cost. Utility Model Content

[0022] 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.

[0023] Please see Figure 1 This utility model provides a technical solution: a pneumatic braking device for a linear rotary motor, including a housing 6. The housing 6 is used to protect and support the remaining structures, ensuring that the remaining devices can be connected and fixed to the housing 6 to prevent accidents during use. The housing 6 is equipped with a motor 1, which drives a supporting mechanism 4 to move. The supporting mechanism 4 is located on the housing 6 and can move up and down between a slider 2 and a mounting mechanism 3. The supporting mechanism 4 is equipped with a slider 2 and a mounting mechanism 3. The slider 2 is used to connect the supporting mechanism 4 and is engaged with a groove 41 on the supporting mechanism 4. The motor 1 drives the supporting mechanism 4 to move between the slider 2 and the mounting mechanism 3. The mounting mechanism 3 brakes the slider 2 and brakes the supporting mechanism 4. The mounting mechanism 3 is equipped with a driver 31, which brakes the supporting mechanism 4.

[0024] Please see Figure 2-5 The driver 31 is equipped with a push rod 32, which is used to connect the brake pad 33. This allows the driver 31 to push the brake pad 33 to contact the bearing mechanism 4 via the push rod 32, thereby braking the bearing mechanism 4. The brake pad 33 is provided at one end of the push rod 32. The brake pad 33 is used to rub within the slide groove 41, thereby braking the bearing mechanism 4. The bearing mechanism 4 is provided with a slide groove 41, which has two functions: first, it can connect with the slider 2 and the mounting mechanism 3 to ensure that the bearing mechanism 4 can move within the slider 2 and the mounting mechanism 3; second, it can cooperate with the brake pad 33 to be inserted into the slide groove 41, thereby effectively braking the bearing mechanism 4. The brake pad 33 and the bearing mechanism 4 are meshed, and this design can better brake the bearing mechanism 4. The slider 2 is engaged with the slide groove 41 and is used to limit the bearing mechanism 4, ensuring that the bearing mechanism 4 can move within the slider 2.

[0025] The driver 31 starts and drives the connected push rod 32, which in turn pushes the brake pad 33 to move. The pre-cut groove 41 of the bearing mechanism 4 is connected at one end to the snap-fit ​​slider 2, which not only connects the two ends but also limits the bearing mechanism 4 so that it can move stably in the limited direction. The other end is connected to the mounting mechanism 3 to ensure that the bearing mechanism 4 can move within it. The brake pad 33 is inserted into the groove 41 of the bearing mechanism 4 under the push of the driver 31. Since the brake pad 33 and the bearing mechanism 4 are interlocked in shape, they can fit better when they rub against each other, generating sufficient friction to gradually reduce the speed of the bearing mechanism 4 and finally achieve braking, effectively preventing it from moving further and ensuring the safe and stable operation of the linear rotary motor system.

[0026] The brake pad 33 is also equipped with a reset rod 34. After the brake pad 33 is pushed into the slide groove 41, the reset rod 34 is connected to a reset spring 35, which pulls the reset rod 34 backward, thereby causing the brake pad 33 to move backward and completing the reset operation. One end of the reset rod 34 is equipped with a reset spring 35, which is used to pull the reset rod 34 and the brake pad 33 backward to complete the reset operation. The reset spring 35 is connected to the mounting mechanism 3 to ensure that the other end of the reset spring 35 is connected to a fixed position to prevent the reset spring 35 from moving with the movement of the brake pad 33. The driver 31 is provided on the back plate 5. The driver 31 is a pneumatic compressor that drives the brake pad 33 by air pressure. The actuator 32 is moved by the actuator, which allows for faster braking. The back plate 5 has an air vent 54 for the actuator 31 to draw air. The air vent 54 is connected to the actuator 31. The back plate 5 has a second connecting pipe 53 connected to the air vent 54. The second connecting pipe 53 allows the actuators 31 on the same side to synchronize. The back plate 5 has a first connecting pipe 52 connected to the air vent 54. The first connecting pipe 52 is used to connect the second connecting pipe 53 and the air inlet 51 to ensure that air can enter the actuator 31. One end of the first connecting pipe 52 has an air inlet 51 for the air to enter the first connecting pipe 52 and then be distributed to the four actuators 31.

[0027] When the pneumatic brake device of the linear rotary motor needs to brake the bearing mechanism 4, the pneumatic compressor driver 31 on the back plate 5 starts to work. By drawing air, the pneumatic pressure drives the push rod 32 connected to it. The push rod 32 then pushes the brake pad 33 into the slide groove 41 of the bearing mechanism 4. Because the brake pad 33 and the bearing mechanism 4 are interlocked, the friction between them generates sufficient friction force, which gradually reduces the speed of the bearing mechanism 4 to achieve braking. At the same time, the driver 31 on the same side works synchronously through the second connecting pipe 53 connected to the air outlet 54. Air enters the first connecting pipe 52 through the air inlet 51, and then enters the driver 31 after connecting to the second connecting pipe 53. After braking is completed, the reset rod 34 connected to the brake pad 33 is pulled back by the reset spring 35 connected to the mounting mechanism 3 at one end, thereby driving the brake pad 33 to move backward to complete the reset, ensuring the safe and stable operation of the linear rotary motor system and the cyclic use of the brake device.

[0028] The slider 2 and the mounting mechanism 3 are arranged in at least two mirror images on both sides of the bearing mechanism 4, and the number of drivers 31 is four, arranged in pairs on both sides of the bearing mechanism 4, thereby enhancing the braking effect.

[0029] When the pneumatic brake device of the linear rotary motor is in use, when the pneumatic brake device of the linear rotary motor needs to brake, the air compressor driver 31 located on the back plate 5 starts to work, drawing air through the air inlet 51, and using air pressure to drive the push rod 32 connected to it. The push rod 32 then pushes the brake pad 33 into the slide groove 41 of the support mechanism 4. Since the slider 2 and the mounting mechanism 3 are at least two mirror images located on both sides of the support mechanism 4, and there are four drivers 31, arranged in pairs on both sides of the support mechanism 4, the braking effect can be enhanced. At the same time, the drivers 31 on the same side work synchronously through the second connecting pipe 53 connected to the air outlet 54. Air enters through the air inlet 51. The first connecting pipe 52 connects to the second connecting pipe 53 and then enters each driver 31. Because the brake pad 33 and the bearing mechanism 4 are interlocked, the friction between them generates sufficient friction force, causing the bearing mechanism 4 to gradually reduce its original moving speed under the drive of the motor 1, thus achieving braking. After braking, the reset rod 34 connected to the brake pad 33 is pulled back by the reset spring 35 connected to the mounting mechanism 3 at one end, thereby driving the brake pad 33 to move backward to complete the reset, ensuring the safe and stable operation of the linear rotary motor system and the cyclic use of the braking device. The outer shell 6 protects and supports the rest of the structure throughout the process, ensuring that each device is connected and fixed, and avoiding accidents during use.
