Description

Technical Field

[0001] The utility model relates to the technical field of brake components, in particular to a gear brake component structure for enhancing walking stability. Background Art

[0002] In the field of modern mechanical transmission, "gear brake assembly" is an important component, and its main function is to provide additional braking or locking functions for the mechanical system when necessary.

[0003] In a traditional transmission mechanism, a gear is usually mounted on the motor shaft, and the gear meshes with a track with a rack. When the motor rotates, this meshing relationship enables the workbench fixed to the motor to move in a straight line or curve along the track, thereby achieving precise position control. This transmission method is widely used in various industrial automation scenarios due to its simple structure, high transmission efficiency, and accurate positioning.

[0004] However, despite the significant advantages of this transmission method, it still faces some challenges in practical applications. In particular, after the motor stops, in order to save costs and simplify the structure, many systems are not equipped with a self-locking function. This means that the workbench may continue to move due to external interference or the reaction force of the load, which not only affects the work accuracy, but also may cause safety problems. To solve this problem, the existing solution is usually to add a locking mechanism to the rack track.

[0005] These locking mechanisms can effectively lock the workbench in general applications. However, in some special application scenarios, especially those equipment that needs to withstand huge loads or impact forces, such as bending machines, stamping machines, and heavy conveying equipment, there are some problems:

[0006] 1. Taking the bending machine as an example, the workpiece will generate a huge reaction force during the bending process. If the impact resistance of the locking mechanism is insufficient, the workpiece may be displaced during the bending process, which will seriously affect the processing accuracy.

[0007] 2. Taking stamping equipment as an example, since the impact force generated during the stamping process is extremely large, if the locking mechanism cannot effectively resist this impact force, it may cause the workbench to move during the stamping process.

[0008] In order to solve this problem, the conventional method is to use a more expensive and harder material to manufacture the locking mechanism, and to increase its volume to enhance the locking force. However, this not only increases the manufacturing cost, but also may affect the overall layout and aesthetics of the device.

[0009] Therefore, how to improve the impact resistance of the locking mechanism and achieve a more stable locking force without increasing the volume and using high-cost hard materials has become a technical problem that the utility model urgently needs to solve. Utility Model Content

[0010] The technical problem solved by the present invention is to provide a gear brake assembly structure that enhances walking stability in response to the defects existing in the above-mentioned prior art, so as to solve the problem raised in the above-mentioned background technology of how to improve the impact resistance and achieve a more stable locking force while avoiding the increase in volume and the use of more expensive hard materials.

[0011] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0012] A gear brake assembly structure for enhancing walking stability, comprising a bracket, a slide rail, a track rack, a motor and a gear; the bracket is fixedly provided with two slide rails; the pulley is slidably connected with the two slide rails; the slide rail is fixedly provided with a track rack; the pulley is fixedly provided with a motor, and a gear meshingly connected with the slide rail rack is fixedly provided on the motor shaft of the motor;

[0013] The gear brake assembly structure for enhancing walking stability also includes a multi-directional limit brake assembly;

[0014] The multi-directional limit brake assembly comprises a cylinder, a limit block, a limit rack, a first guide limit body and a second guide limit body;

[0015] The cylinder is fixedly arranged on the bracket, the cylinder comprises a cylinder rod, and the cylinder rod of the cylinder comprises a pushing end;

[0016] The push end of the cylinder rod is fixedly connected to the rear side of the limit block, and the front side of the limit block is arranged on a limit rack matched with the track rack;

[0017] On the bracket, a first guide limiter and a second guide limiter are respectively fixedly arranged on the left and right sides of the limiter block;

[0018] A sliding space for the limiting block to move forward and backward is formed between the first guide limiting body and the second guide limiting body.

[0019] As a further solution of the utility model, the number of the multi-directional limit brake assemblies is four, and the four multi-directional limit brake assemblies are respectively located at four angular positions of the pulley.

[0020] As a further solution of the utility model, the first guide limiting body and the second guide limiting body are respectively fixedly connected to the bracket.

[0021] As a further solution of the utility model, the number of cylinder rods is 2.

[0022] As a further solution of the utility model, the cylinder rod includes a pushing state and a retracted state. When the cylinder rod is in the pushing state, the limit rack on the limit block is meshed and connected with the track rack. When the cylinder rod is in the retracted state, the limit rack on the limit block is not meshed and connected with the track rack.

[0023] Compared with the prior art, the beneficial effect of the utility model is that under high load or impact force, such as in heavy machinery and equipment such as bending machines, the multi-directional limit brake assembly can effectively resist external interference and the reaction force of the load. In particular, when the cylinder rod is in the pushing state, the limit rack is engaged with the track rack, and the first guide limit body and the second guide limit body provide solid support for this engagement position in the left and right directions. At the same time, combined with the front and rear direction restrictions of the slide rail and the limit block, a closed limit space in the front, rear, left and right directions is formed, ensuring the stable locking of the workbench under the action of huge bending force and other loads, greatly improving the processing accuracy and work safety.

[0036] Slide rails 2 and pulleys 3: The pulleys 3 are connected to the two slide rails 2 in a sliding manner, so that the pulleys 3 can move smoothly along the slide rails 2. A track rack 4 is fixedly arranged on the slide rails 2, which is a key component that cooperates with the gear 5.

[0037] Motor 6 and gear 5: The pulley 3 is fixedly provided with a motor 6, and a gear 5 meshingly connected with the track rack 4 on the slide rail 2 is fixedly provided on the motor shaft of the motor 6. When the motor 6 rotates, the meshing action of the gear 5 and the track rack 4 pushes the pulley 3 to move along the slide rail 2.

[0038] Multi-directional limit brake assembly: This is the core innovative part of the present invention. The multi-directional limit brake assembly includes a cylinder 7, a limit block 8, a limit rack 9, a first guide limit body 10 and a second guide limit body 11. The cylinder 7 is fixedly arranged on the bracket 1, and includes a cylinder rod 12, and the cylinder rod 12 has a push end. The push end of the cylinder rod 12 is fixedly connected to the rear side of the limit block 8, and the front side of the limit block 8 is provided with a limit rack 9 that cooperates with the track rack 4. On the bracket 1, the left and right sides of the limit block 8 are respectively fixedly provided with a first guide limit body 10 and a second guide limit body 11. A sliding space for the limit block 8 to move forward and backward is formed between the two guide limit bodies. When the cylinder rod 12 is in a pushing state, the limit rack 9 on the limit block 8 is meshed and connected with the track rack 4 to realize the braking function; when the cylinder rod 12 is in a retracted state, the limit rack 9 on the limit block 8 is not meshed and connected with the track rack 4, allowing the pulley 3 to move normally.

[0039] Furthermore, the number of multi-directional limit brake assemblies is four, and the four multi-directional limit brake assemblies are respectively located at four angle positions of the pulley 3. This layout ensures uniform distribution of braking force and higher stability. The first guide limit body 10 and the second guide limit body 11 are respectively fixedly connected to the bracket 1, providing a solid support structure. In addition, the number of cylinder rods 12 can be two or more, and the specific number is determined according to application requirements. In this embodiment, two cylinder rods 12 are preferably provided to provide redundancy and higher reliability.

[0040] Through the above technical scheme, the gear brake assembly structure for enhancing walking stability of the present invention achieves the following beneficial effects: by combining the gear 5 transmission and the multi-directional limit brake assembly, excellent braking performance and stability are provided; the design of the multi-directional limit brake assembly ensures uniform distribution and rapid response of the braking force; the entire assembly structure is compact, highly reliable and easy to maintain.

[0041] Embodiment 1:

[0042] This embodiment provides a gear brake assembly structure that enhances walking stability, which is particularly suitable for equipment such as bending machines and punching machines that need to withstand huge loads or impact forces. The assembly combines the gear 5 transmission and the multi-directional limit brake assembly to achieve stable braking and precise position control under high loads or impact forces.

[0043] Specifically, the gear brake assembly includes a bracket 1, a slide rail 2, a track rack 4, a motor 6, a gear 5, and a multi-directional limit brake assembly. The bracket 1 is the basic structure of the entire assembly, and two slide rails 2 are fixedly arranged on it. The pulley 3 is slidably connected with the two slide rails 2, so that the pulley 3 can move smoothly along the slide rails 2. The slide rail 2 is fixedly provided with a track rack 4, which is a key component that cooperates with the gear 5.

[0044] The pulley 3 is fixedly provided with a motor 6, and the motor shaft of the motor 6 is fixedly provided with a gear 5 meshing with the track rack 4 on the slide rail 2. When the motor 6 rotates, the meshing action of the gear 5 and the track rack 4 pushes the pulley 3 to move along the slide rail 2 in a straight line or curve, thereby realizing precise position control. This transmission mode has the advantages of simple structure, high transmission efficiency, and accurate positioning.

[0045] In order to enhance the braking performance and stability, the present embodiment particularly introduces a multi-directional limit brake assembly. The assembly includes a cylinder 7, a limit block 8, a limit rack 9, a first guide limit body 10 and a second guide limit body 11. The cylinder 7 is fixedly arranged on the bracket 1 and includes a cylinder rod 12, and the cylinder rod 12 has a push end. The push end of the cylinder rod 12 is fixedly connected to the rear side of the limit block 8, and the front side of the limit block 8 is provided with a limit rack 9 that matches the track rack 4.

[0046] On the bracket 1, a first guide limiter 10 and a second guide limiter 11 are fixedly arranged on the left and right sides of the limiter 8, respectively. A sliding space for the limiter 8 to move forward and backward is formed between the two guide limiters. When the cylinder rod 12 is in the pushing state, the limiter rack 9 on the limiter 8 is meshed and connected with the track rack 4 to achieve the braking function; when the cylinder rod 12 is in the retracted state, the limiter rack 9 on the limiter 8 is not meshed and connected with the track rack 4, allowing the pulley 3 to move normally.

[0047] In this embodiment, there are four multi-directional limit brake assemblies, which are respectively located at four angles of the pulley 3. This layout ensures uniform distribution of the braking force and higher stability. At the same time, the first guide limit body 10 and the second guide limit body 11 are respectively fixedly connected to the bracket 1, providing a solid support structure.

[0048] At the same time, the beneficial effects brought by the utility model will be more fully demonstrated in the following specific application scenarios and methods:

[0049] 1. Excellent stability and impact resistance: Under high load or impact force, such as in heavy machinery and equipment such as bending machines, the multi-directional limit brake assembly can effectively resist external interference and load reaction force. In particular, when the cylinder rod 12 is in the push state, the limit rack 9 is engaged with the track rack 4, and the first guide limit body 10 and the second guide limit body 11 provide solid support for this engagement position in the left and right directions. At the same time, combined with the front and rear direction restrictions of the slide rail 2 and the limit block 8, a multi-directional closed limit space in the front, back, left and right directions is formed, ensuring the stable locking of the workbench under the huge bending force and other loads, greatly improving the processing accuracy and work safety.

[0050] 2. Optimized braking force distribution and simplified structure: Four multi-directional limit brake components are distributed at four angles of the pulley 3, which not only ensures the uniform distribution of braking force, but also effectively simplifies the overall structure of the mechanical system. This layout avoids the offset or tilt caused by uneven force, prolongs the service life of the mechanical system, and achieves more stable locking force and higher impact resistance without increasing manufacturing costs.

[0051] 3. Easy to integrate and maintain: The gear brake assembly is simple and clear in design and easy to integrate with the existing transmission mechanism. Its structural characteristics make maintenance and repair work easier and greatly reduce operating costs.

[0052] 4. Improve work efficiency and precision: This application significantly improves work efficiency and precision by ensuring that the mechanical system can stop quickly and stably when needed, especially in automation applications that require precise position control, such as bending machines, punching machines and other heavy machinery and equipment. This is crucial to improving the overall performance of the production line and meeting high-precision processing needs.

[0053] In summary, this patent application provides an efficient, stable and economical gear 5 braking solution for the modern mechanical transmission field through ingenious structural design and technical innovation, especially the application of the sliding space formed between the first guide limiter 10 and the second guide limiter 11. This innovative design has achieved remarkable results in improving the stability of the braking system, optimizing the distribution of braking force, simplifying the structure, reducing costs, and improving working accuracy and efficiency.
