[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] According to one embodiment of the present application, a lifting mechanism is provided. Figures 1 to 4 As shown, the lifting mechanism includes a mounting base 1, a lifting body 2, and a brake assembly 3. The mounting base 1 is provided with a brake portion 11; the lifting body 2 is slidably mounted on the mounting base 1; and the brake assembly 3 is mounted on the lifting body 2. The brake assembly 3 includes a brake member 31, a first drive member 32, and a second drive member 33. The first drive member 32 is adapted to drive the brake member 31 away from the brake portion 11. When the first drive member 32 fails, the second drive member 33 can drive the brake member 31 toward the brake portion 11. The brake member 31 can cooperate with the brake portion 11 to brake the lifting body 2.

[0033] In this embodiment, the lifting body 2 is slidably mounted on the mounting base 1, and a braking portion 11 is provided on the mounting base 1. A brake assembly 3 is provided on the lifting body 2. The brake assembly 3 includes a brake member 31, a first drive member 32 and a second drive member 33. The first drive member 32 can drive the brake member 31 away from the brake portion 11. The first drive member 32 and the lifting body 2 share a power supply or gas source. When the lifting body 2 encounters a sudden power outage or gas outage during normal operation, the lifting body 2 will start to fall, and the first drive member 32 will also fail. At this time, the second drive member 33 can drive the brake member 31 to move toward the brake portion 11, and the brake member 31 can cooperate with the brake portion 11 to brake the lifting body 2, thereby effectively preventing the lifting body 2 from being damaged due to power outage or gas outage.

[0034] In this embodiment, the lifting body 2 is suitable for assembling a processing device for processing other workpieces, and the lifting body 2 slides along the mounting seat 1 to drive the processing device to move up or down. The lifting body 2 can be driven to lift by a second cylinder or a motor. The first driving member 32 of the brake assembly 3 shares a power supply or air source with the lifting body 2. When the lifting body 2 is operating normally, the first driving member 32 can drive the brake member 31 away from the brake part 11 so that the lifting body 2 can operate normally; when the lifting body 2 encounters a sudden power outage or gas outage, the first driving member 32 will also be powered off or gas cut off, thereby rendering the first driving member 32 ineffective. At this time, the second driving member 33 can automatically drive the brake member 31 to move toward the brake part 11, and the brake member 31 can cooperate with the brake part 11 to brake the lifting body 2 to prevent the lifting body 2 from falling and being damaged.

[0035] When the first driving member 32 is operating normally, the force exerted by the first driving member 32 on the brake member 31 is greater than the force exerted by the second driving member 33 on the brake member 31, so that the first driving member 32 can stably drive the brake member 31 away from the braking portion 11. When the first driving member 32 fails, the force exerted by the first driving member 32 on the brake member 31 is less than the force exerted by the second driving member 33 on the brake member 31, so that the second driving member 33 can stably drive the brake member 31 to move toward the braking portion 11.

[0036] In this embodiment, the brake assembly 3 can also be fixedly mounted on the mounting base 1, and the lifting body 2 is correspondingly provided with a brake portion 11 that cooperates with the brake member 31. Alternatively, the mounting base 1 and the lifting mechanism are each provided with a brake portion 11 and a brake assembly 3, with the brake assembly 3 on one side being able to correspond to the brake portion 11 on the other side.

[0037] In one example, Figure 2 and Figure 3 As shown, the first driving member 32 includes a first cylinder, which is suitable for driving the braking member 31 away from the braking portion 11.

[0038] like Figures 2 to 4 As shown, in this example, the first driving member 32 can be a first cylinder, the brake member 31 is slidably mounted on the shell 34, and the first cylinder is mounted on the shell 34. The shell 34 can be fixedly connected to the lifting body 2 by fasteners such as bolts or screws, or the shell 34 and the lifting body 2 can be fixedly connected by means of clamping or welding. The piston rod of the first cylinder is transmission-connected to the brake member 31 and can drive the brake member 31 to move away from the brake part 11. The first cylinder and the second cylinder of the lifting body 2 share an air source. When the second cylinder operates normally, the first cylinder can also operate normally, that is, drive the brake member 31 to move away from the brake part 11. When the second cylinder suddenly stops operating, the first cylinder will also stop operating, that is, the first cylinder fails. At this time, the second driving member 33 can drive the brake member 31 to move toward the brake part 11, so that the brake member 31 can cooperate with the brake part 11 on the mounting base 1 to form a brake, thereby braking the lifting body 2 to prevent the lifting body 2 from falling and being damaged.

[0039] In one example, Figure 4 As shown, the second driving member 33 includes an elastic member. After the first cylinder fails, the elastic member can drive the braking member 31 to move toward the braking portion 11.

[0040] like Figure 4 As shown, in this example, the second driving member 33 can be an elastic member, which is disposed in the housing 34. One end of the elastic member abuts against the inner wall of the housing 34, and the other end abuts against the brake member 31. The elastic member can push the brake member 31 toward the braking portion 11 after the first driving member 32 fails. For example, the second driving member 33 can be a compression spring.

[0041] Alternatively, the second driving member 33 may be a tension spring, one end of which is connected to the inner wall of the housing 34 and the other end is connected to the brake member 31. After the first driving member 32 fails, the tension spring can pull the brake member 31 toward the braking portion 11.

[0042] In this example, multiple elastic members can be provided, and the multiple elastic members are arranged at intervals. The elastic members can synchronously drive the brake member 31 to move toward the brake portion 11, thereby facilitating improving the reliability of the brake assembly 3 braking the lifting body 2.

[0043] In one example, Figures 2 to 4 As shown, the brake member 31 includes a brake rod, the first cylinder is transmission-connected to the brake rod, one end of the elastic member is against the brake rod, and the elastic member can push the brake rod to move toward the braking portion 11.

[0044] like Figures 2 to 4As shown, in this example, the brake member 31 can be a brake rod. For example, the brake rod can be made of a metal material such as aluminum alloy or stainless steel. Those skilled in the art can determine the material based on actual conditions and are not specifically limited here. The output end of the first cylinder is drivingly connected to the brake rod. One end of the elastic member abuts the brake rod, and the other end abuts the inner wall of the housing 34. The elastic member can push the brake member 31 toward the braking portion 11 after the first cylinder fails, causing the brake rod and the braking portion 11 to cooperate and brake.

[0045] In this example, the piston rod of the first cylinder is connected to the brake rod via a connecting plate. For example, one end of the connecting plate is connected to the piston rod, and the other end is connected to the brake rod. The first cylinder can drive the connecting plate to the left, which in turn drives the brake rod to the left. If the first cylinder fails, the elastic member can drive the brake rod to the right.

[0046] In this example, the brake rod may be a cylindrical rod or a prismatic rod, or the brake member 31 may also be of other structures. Those skilled in the art may determine this according to actual circumstances, and no specific limitation is made here.

[0047] In one example, the braking portion 11 includes a braking groove, and the second driving member 33 can drive the braking member 31 to be inserted into the braking groove.

[0048] like Figure 2 As shown, in this example, a brake groove is provided on the side wall of the mounting base 1. When the first driving member 32 fails, the second driving member 33 can drive the brake member 31 to be inserted into the brake groove, thereby applying a brake. For example, the brake member 31 is a brake rod, and the second driving member 33 can drive the brake rod to be inserted into the brake groove.

[0049] like Figure 2 As shown, in this example, the brake groove can be a vertically oriented strip-shaped groove. As the lifting body 2 descends from above, the strip-shaped brake groove facilitates insertion of the brake rod into the groove. For example, the brake groove can be formed by cutting or milling along a predetermined path on the surface of the mounting base 1 using a tool or other tool. The specific length and dimensions of the brake groove can be determined by those skilled in the art based on practical circumstances and are not specifically defined herein.

[0050] Alternatively, the brake portion 11 may have other structures, such as a horizontally disposed limit rod, with the second drive member 33 driving the brake rod toward the limit rod, so that the brake rod can rest on top of the limit rod, thereby also achieving braking. Alternatively, the brake portion 11 and the brake member 31 may have mutually engaged sawtooth structures. The structures of the brake portion 11 and the brake member 31 can be determined by those skilled in the art based on actual circumstances and are not specifically limited herein.

[0051] In one example, Figure 1 and Figure 2 As shown, the mounting seat 1 is provided with a plurality of braking grooves spaced apart in the sliding direction of the lifting body 2 .

[0052] like Figure 1 and Figure 2 As shown, in this example, the lift body 2 can slide vertically, and the mounting base 1 is provided with multiple brake grooves spaced apart vertically. When the lift mechanism falls, the second drive member 33 drives the brake rod toward the brake groove, allowing the brake rod to be inserted into the brake groove. The provision of multiple brake grooves improves the reliability of the brake rod's insertion, thereby enhancing the safety of the lift body 2.

[0053] For example, the mounting base 1 may be provided with two, three, four, five, six, or seven brake grooves spaced apart. Those skilled in the art may determine this based on actual circumstances, and this is not specifically limited here. Furthermore, those skilled in the art may determine the specific spacing between two adjacent brake grooves based on actual circumstances, and this is not specifically limited here.

[0054] In this example, the sliding direction of the lifting body 2 is vertical, that is, the sliding direction of the lifting body 2 is perpendicular to the horizontal plane. Alternatively, the sliding direction of the lifting body 2 can also have a certain angle with the horizontal plane. Those skilled in the art can determine this according to actual circumstances and it is not specifically limited here.

[0055] In one example, Figure 1 and Figure 3 As shown, there are multiple brake assemblies 3, and the multiple brake assemblies 3 are arranged at intervals on the lifting body 2.

[0056] like Figure 1 and Figure 3 As shown, the lifting body 2 is equipped with multiple brake assemblies 3, which are arranged at intervals. When the lifting mechanism falls, the second driving member 33 in each brake assembly 3 can drive the brake member 31 to move toward the braking portion 11 of the mounting base 1. The provision of multiple brake assemblies 3 helps improve braking reliability.

[0057] For example, the number of brake assemblies 3 can be two, three, four or five, etc. Those skilled in the art can determine this based on actual conditions, and no specific limitation is made here.

[0058] In this example, the braking portion 11 can be a braking groove, and the braking member 31 can be a braking rod. When multiple braking assemblies 3 are arranged, the lifting assembly can fall to any position, and there is at least one brake rod that can correspond to the braking groove, so as to improve the reliability of braking.

[0059] In one example, Figure 1 As shown, the mounting base 1 includes two columns 12 arranged at an interval, and both ends of the lifting body 2 are slidably connected to the columns 12 respectively, and each column 12 is provided with the braking part 11.

[0060] like Figure 1 As shown, the mounting base 1 comprises two spaced-apart columns 12, and the opposite ends of the lifting body 2 are slidably connected to the two columns 12, respectively, so that the lifting body 2 can slide along the columns 12. A brake portion 11 is provided on each column 12, and brake assemblies 3 are also provided at corresponding positions on both sides of the lifting body 2, thereby improving braking reliability.

[0061] In this example, the column 12 is provided with a slide rail, and the mounting base 1 is correspondingly provided with a slide groove, which can be clamped on the slide rail and enable the lifting body 2 to slide along the slide rail. The slide rail can be arranged in a vertical direction, or the slide rail can also be arranged at an angle.

[0062] In one example, Figure 1 As shown, a plurality of brake assemblies 3 are provided on both sides of the lifting body 2 .

[0063] like Figure 1 As shown, in this example, multiple brake assemblies 3 are mounted on both sides of the lifting body 2, with the multiple brake assemblies 3 on each side spaced apart along the sliding direction of the lifting body 2. When the lifting mechanism falls, the second driving member 33 in each brake assembly 3 can drive the brake member 31 toward the braking portion 11 on the corresponding support. The provision of multiple brake assemblies 3 helps improve braking reliability.

[0064] For example, two, three, four or five brake assemblies 3 may be provided on each side, and those skilled in the art may determine this according to actual conditions, and no specific limitation is made here.

[0065] According to another embodiment of the present invention, a processing device is provided. The processing device includes the lifting mechanism of the above embodiment. The lifting mechanism includes a mounting seat 1, a lifting body 2 and a brake assembly 3. The mounting seat 1 is provided with a brake portion 11; the lifting body 2 is slidably mounted on the mounting seat 1; the brake assembly 3 is mounted on the lifting body 2, and the brake assembly 3 includes a brake member 31, a first drive member 32 and a second drive member 33. The first drive member 32 is suitable for driving the brake member 31 away from the brake portion 11. When the first drive member 32 fails, the second drive member 33 can drive the brake member 31 to move toward the brake portion 11, and the brake member 31 can cooperate with the brake portion 11 to brake the lifting body 2.

[0066] In this embodiment, the lifting body 2 is suitable for assembling a processing device for processing other workpieces. The lifting body 2 slides along the mounting seat 1 to drive the processing device to move upward or downward so that the processing device can process the workpiece at the corresponding position. The lifting body 2 is slidably mounted on the mounting seat 1. The mounting seat 1 is provided with a braking portion 11. The lifting body 2 is provided with a braking assembly 3. The braking assembly 3 includes a braking member 31, a first driving member 32 and a second driving member 33. The first driving member 32 can drive the braking member 31 away from the braking portion 11. The first driving member 32 and the lifting body 2 share a power supply or air source. When the lifting body 2 encounters a sudden power outage or air outage during normal operation, the first driving member 32 will also fail. At this time, the second driving member 33 can drive the braking member 31 to move toward the braking portion 11, and the braking member 31 can cooperate with the braking portion 11 to brake the lifting body 2, thereby effectively preventing the lifting body 2 from being damaged due to power outage or air outage.

[0067] Of course, the processing equipment of the present application also includes at least all the beneficial effects of the above embodiments, which will not be elaborated here.

[0068] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
