Description

Technical Field

[0001] This invention relates to the technical field of protective cover switch structures, and specifically to an automatic protective cover switch structure and processing equipment. Background Technology

[0002] A protective cover is typically installed on top of the processing equipment. When the equipment is operating, the cover opens to seal the top, providing dust protection and safety. The front of the equipment has an outer protective component, and the top has a crossbeam assembly. In existing technology, the cover is movably mounted on top of the equipment. Cylinders are also installed on both sides of the top of the equipment, extending along the direction of movement of the cover, making it a retractable cover. The first side of the cover is connected to the crossbeam assembly, and the driving end of the cylinder is connected to the second side. The cylinder extends to drive the second side of the cover to move away from the crossbeam assembly, causing the cover to extend and abut against the outer protective component at the front of the equipment, forming a fully enclosed protective structure above the equipment. When the cover needs to be opened, the cylinder retracts to drive the second end of the cover towards the crossbeam assembly.

[0003] The opening and closing of the aforementioned protective cover is driven by a cylinder. The cylinder extends along the direction of movement of the protective cover. The cylinder stroke is long, occupies a large space, and the cylinder installation position is restricted. Furthermore, when the cylinders on both sides move asynchronously, jamming is likely to occur. Summary of the Invention

[0004] In view of this, the present invention provides an automatic cover switch structure and processing equipment to solve the problems of large footprint, restricted installation, and easy jamming during the switching process in the prior art.

[0005] In a first aspect, the present invention provides an automatic opening and closing structure for a protective cover, comprising:

[0006] A beam assembly is adapted to be movably mounted on an object to be covered; an outer protective component is provided at the first end of the object to be covered; a first fixed bracket is provided on the outer protective component;

[0007] A first drive mechanism is connected to the crossbeam assembly, and the first drive mechanism is used to drive the crossbeam assembly to move along the object to be covered.

[0008] A telescopic shield assembly, wherein a first side of the telescopic shield assembly is connected to the crossbeam assembly; the side of the telescopic shield assembly facing away from the crossbeam assembly is its second side;

[0009] The bracket connection mechanism has a first side fixed to the second side of the telescopic shield assembly, and the second side extends toward the first fixed bracket.

[0010] When the telescopic shield assembly performs a closing action, the first drive mechanism drives the crossbeam assembly and the telescopic shield assembly to move toward the outer protective component, and causes the telescopic shield assembly to abut against the outer protective component. The second side of the bracket connecting mechanism is connected to the first fixed bracket, and the first drive mechanism drives the crossbeam assembly to move away from the outer protective component to unfold the telescopic shield assembly. When the telescopic shield assembly performs an opening action, the second side of the bracket connecting mechanism is disconnected from the first fixed bracket, and the first drive mechanism drives the crossbeam assembly and the telescopic shield assembly to move away from the outer protective component.

[0011] Beneficial effects: In use, the automatic switch structure of this protective cover utilizes a bracket connecting mechanism in conjunction with a first drive mechanism to control the opening and closing of the telescopic protective cover assembly. The bracket connecting mechanism is located on the second side of the telescopic protective cover assembly, occupying minimal space and facilitating its placement. When closing the telescopic protective cover assembly, the first drive mechanism first moves the assembly close to the outer protective component, bringing the bracket connecting mechanism closer to the first fixed bracket. The bracket connecting mechanism then connects to the first fixed bracket, resulting in a short stroke and minimal space requirement. When closing the telescopic protective cover assembly, the second side of the assembly is first fixed to the first fixed bracket via the bracket connecting mechanism, maintaining relative fixation between the second side and the outer protective component. The first drive mechanism then moves the first side of the assembly away from the outer protective component. When opening the telescopic protective cover assembly, the bracket connecting mechanism disengages from the first fixed bracket, and the first drive mechanism moves the assembly away from the outer protective component. This effectively prevents jamming during the opening and closing process, thereby reducing equipment failure rates and improving production efficiency and maintenance costs.

[0012] In one optional embodiment, the bracket connection mechanism includes a bracket clamping drive mechanism. When the telescopic cover assembly performs a closing action, the clamping end of the bracket clamping drive mechanism clamps the first fixed bracket; when the telescopic cover assembly performs an opening action, the clamping end of the bracket clamping drive mechanism opens to release the first fixed bracket.

[0013] Beneficial effects: The bracket clamping drive mechanism fixes the second side of the telescopic shield assembly to the first fixed bracket by clamping, which is secure and facilitates the subsequent movement of the first drive mechanism away from the outer protective component to unfold the telescopic shield assembly.

[0014] In one optional embodiment, the bracket clamping drive mechanism includes a bracket clamping cylinder, which is horizontally extended and fixed to the telescopic cover assembly. The first fixed bracket includes a first abutment plate, which extends vertically and is disposed toward the telescopic cover assembly. When the telescopic cover assembly performs a closing action, the clamping end of the bracket clamping cylinder engages with the first abutment plate. When the telescopic cover assembly performs an opening action, the clamping end of the bracket clamping cylinder opens to disengage from the first abutment plate.

[0015] Beneficial effects: When the telescopic protective cover assembly performs the closing action, the clamping end of the bracket clamping cylinder abuts against the side of the first abutment plate facing away from the crossbeam assembly. During the movement of the crossbeam assembly away from the outer protective component, it can ensure that the clamping end is firmly locked onto the first abutment plate, preventing connection failure.

[0016] In one optional embodiment, the telescopic shield assembly is provided with the bracket connecting mechanism at both ends perpendicular to its direction of movement, and the first fixed bracket and the bracket connecting mechanism are respectively arranged on the outer protective component.

[0017] Beneficial effects: When the telescopic shield assembly is closed, the bracket connection mechanism at both ends of the telescopic shield assembly is connected to the two first fixed brackets respectively, so as to position the second side of the telescopic shield assembly on the outer protective component from both sides, enhance the positioning effect, and ensure that the second side of the telescopic shield assembly facing the outer protective component is tightly pressed against the outer protective component, thereby ensuring the sealing and protection effect.

[0018] In one optional embodiment, the system further includes a beam connecting mechanism and a second fixed bracket; the beam connecting mechanism is located on the second side of the telescopic shield assembly, and the second fixed bracket is located on the beam assembly.

[0019] When the telescopic shield assembly performs the opening action, the first drive mechanism drives the crossbeam assembly to move toward the outer protective component, and the crossbeam connecting mechanism is connected to the second fixed bracket; when the telescopic shield assembly performs the closing action, the crossbeam connecting mechanism is disconnected from the second fixed bracket.

[0020] Beneficial effects: The crossbeam connecting mechanism connects to the second fixed bracket. During the process of the first drive mechanism driving the crossbeam assembly to move away from the outer protective component, the telescopic cover assembly is compressed to its shortest state. The crossbeam assembly can be fully opened after moving a short distance away from the outer protective component, which helps to reduce the stroke of the crossbeam assembly and the first drive mechanism and reduce space occupation.

[0021] In one optional embodiment, the beam connecting mechanism includes a beam clamping drive mechanism; when the telescopic cover assembly performs an opening action, the clamping end of the beam clamping drive mechanism clamps the second fixed bracket; when the telescopic cover assembly performs a closing action, the clamping end of the beam clamping drive mechanism opens to release the second fixed bracket.

[0022] Beneficial effect: The beam clamping drive mechanism fixes the second side of the telescopic cover assembly to the second fixed bracket by clamping, which is secure and facilitates the subsequent movement of the first drive mechanism away from the outer protective component to open the telescopic cover assembly.

[0023] In one optional embodiment, the beam clamping drive mechanism includes a beam clamping cylinder; the beam clamping cylinder is horizontally extended and fixed to the telescopic cover assembly, the second fixed bracket includes a second abutment plate, the second abutment plate extends vertically and is disposed toward the telescopic cover assembly, when the telescopic cover assembly performs an opening action, the clamping end of the beam clamping cylinder is engaged with the second abutment plate; when the telescopic cover assembly performs a closing action, the clamping end of the beam clamping cylinder opens to disengage from the second abutment plate.

[0024] In one optional embodiment, the telescopic shield assembly is provided with the beam connecting mechanism at both ends perpendicular to its direction of movement, and the second fixed bracket is provided on the beam assembly in a one-to-one correspondence with the beam connecting mechanism.

[0025] In one optional embodiment, the telescopic shield assembly includes a telescopic shield, a first end plate, and a second end plate;

[0026] The first end plate and the second end plate are respectively disposed at both ends of the telescopic cover. The first end plate is disposed on the crossbeam assembly, and the second end plate is adapted to abut against the outer protective component. The bracket connecting mechanism and the crossbeam connecting mechanism are both connected to the second end plate.

[0027] Secondly, the present invention also provides a processing apparatus, comprising:

[0028] frame;

[0029] An external protective component is located at the first end of the frame;

[0030] In any of the above-described automatic cover switching structures, the crossbeam assembly is movably mounted on the frame. The processing equipment including the automatic cover switching structure has the same effects as the automatic cover switching structure, and will not be described further here.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0043] According to an embodiment of the present invention, an automatic cover opening and closing structure is provided, including a beam assembly 1, a first drive mechanism, a telescopic cover assembly, and a bracket connection mechanism 6.

[0044] The device comprises a beam assembly 1 movably mounted on an object to be covered; an outer protective component 2 is provided at the first end of the object; a first fixed bracket 3 is provided on the outer protective component 2; a first drive mechanism is connected to the beam assembly 1 and is used to drive the beam assembly 1 to move along the object to be covered; a first side of a telescopic cover assembly is connected to the beam assembly 1; the side of the telescopic cover assembly facing away from the beam assembly 1 is its second side; a first side of a bracket connecting mechanism 6 is fixed to the second side of the telescopic cover assembly, and the second side of the bracket connecting mechanism 6 extends toward the first fixed bracket 3; when the telescopic cover assembly performs a closing action, the first drive mechanism drives the beam assembly 1 and the telescopic cover assembly to move toward the outer protective component 2, and the telescopic cover assembly abuts against the outer protective component 2, and the second side of the bracket connecting mechanism 6 is connected to the first fixed bracket 3. The first drive mechanism drives the beam assembly 1 to move away from the outer protective component 2 to unfold the telescopic cover assembly; when the telescopic cover assembly performs an opening action, the second side of the bracket connecting mechanism 6 is disconnected from the first fixed bracket 3. The first drive mechanism drives the beam assembly 1 and the telescopic cover assembly to move away from the outer protective component 2.

[0045] When using this automatic cover switch structure, it is placed over the object to be covered. When the telescopic cover assembly needs to be closed, the first drive mechanism drives the crossbeam assembly 1 to move towards the outer protective component 2. The crossbeam assembly 1 drives the telescopic cover assembly to move synchronously towards the outer protective component 2 until the second side of the telescopic cover assembly abuts against the outer protective component 2. At this time, the bracket connecting mechanism 6 approaches the first fixed bracket 3 and actuates to connect the first fixed bracket 3, thereby keeping the second side of the telescopic cover assembly relatively fixed to the outer protective component 2. The first drive mechanism then drives the crossbeam assembly 1 to move away from the outer protective component 2. During the movement of the crossbeam assembly 1, it drives the first side of the telescopic cover assembly to move away from the outer protective component 2, thereby lengthening and unfolding the telescopic cover assembly so that the telescopic cover assembly seals over the object to be covered. At this time, the telescopic cover assembly is in the closed state, and the machine tool operates normally. When it is necessary to open the telescopic protective cover assembly, the bracket connecting mechanism 6 is disconnected from the first fixed bracket 3, and the first drive mechanism drives the crossbeam assembly 1 to move away from the outer protective component 2, thereby synchronously driving the entire telescopic protective cover assembly to move away from the outer protective component 2. The telescopic protective cover assembly moves away from the outer protective component 2 to open the telescopic protective cover assembly. At this time, the telescopic protective cover assembly is in the open state, and the operator can use the overhead crane to lift and lower the workpiece.

[0046] The bracket connecting mechanism 6, in conjunction with the first drive mechanism, controls the closing or opening of the telescopic protective cover assembly. The bracket connecting mechanism 6 is located on the second side of the telescopic protective cover assembly, occupying a small space and being easy to arrange. When closing the telescopic protective cover assembly, the first drive mechanism first drives the telescopic protective cover assembly close to the outer protective component 2, causing the bracket connecting mechanism 6 to approach the first fixed bracket 3. The bracket connecting mechanism 6 then actuates to connect to the first fixed bracket 3, resulting in a short stroke and small footprint. When closing the telescopic protective cover assembly, the second side of the telescopic protective cover assembly is first connected and fixed to the first fixed bracket 3 via the bracket connecting mechanism 6, keeping the second side of the telescopic protective cover assembly relatively fixed to the outer protective component 2. The first drive mechanism then drives the first side of the telescopic protective cover assembly to move away from the outer protective component 2. When it is necessary to open the telescopic protective cover assembly, the bracket connecting mechanism 6 disengages from the first fixed bracket 3, and the first drive mechanism drives the telescopic protective cover assembly to move away from the outer protective component 2. This effectively prevents jamming during the opening and closing of the telescopic protective cover assembly, thereby effectively reducing the equipment failure rate and improving production efficiency and maintenance costs.

[0047] Optionally, in one embodiment, the bracket connection mechanism 6 includes a bracket clamping drive mechanism. When the telescopic shield assembly performs a closing action, the clamping end of the bracket clamping drive mechanism clamps the first fixed bracket 3; when the telescopic shield assembly performs an opening action, the clamping end of the bracket clamping drive mechanism opens to release the first fixed bracket 3. The bracket clamping drive mechanism securely fixes the second side of the telescopic shield assembly to the first fixed bracket 3 by clamping, thereby facilitating the subsequent movement of the first drive mechanism away from the outer protective component 2 to unfold the telescopic shield assembly.

[0048] Optionally, in one embodiment, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the bracket clamping drive mechanism includes a bracket clamping cylinder, which is horizontally extended and fixed on the telescopic cover assembly. The first fixed bracket 3 includes a first abutment plate 301, which extends vertically and faces the telescopic cover assembly. When the telescopic cover assembly performs a closing action, the clamping end of the bracket clamping cylinder engages with the first abutment plate 301 to fix the second side of the telescopic cover assembly on the first fixed bracket 3. The clamping end of the bracket clamping cylinder abuts against the side of the first abutment plate 301 facing away from the crossbeam assembly 1. During the movement of the crossbeam assembly 1 away from the outer protective component 2, the clamping end can be firmly engaged with the first abutment plate 301 to prevent connection failure. When the telescopic cover assembly performs an opening action, the clamping end of the bracket clamping cylinder opens to disengage from the first abutment plate 301.

[0049] Specifically, in this embodiment, the first fixed bracket 3 includes three mutually perpendicular connecting plates, one of which serves as the first abutment plate 301, and the other connecting plate is adapted to be fixed on the outer protective component 2.

[0050] In other embodiments, the bracket clamping drive mechanism may also include any clamping drive mechanism with two jaws. In this case, the first fixed bracket 3 is provided with a snap-fit ​​hole, and the two jaws of the clamping drive mechanism are clamped and fixed on the snap-fit ​​hole so that the clamping drive mechanism and the first fixed bracket 3 remain relatively fixed.

[0051] In other embodiments, the bracket connecting mechanism 6 may also include an electromagnet, and the first fixed bracket 3 is made of ferromagnetic material. When it is necessary to connect the first fixed bracket 3, the electromagnet is energized to firmly attract the first fixed bracket 3, so as to fix the second side of the telescopic cover assembly on the first fixed bracket 3; when it is necessary to disconnect the bracket connecting mechanism 6 from the first fixed bracket 3, the electromagnet is de-energized and can move away from the first fixed bracket 3.

[0052] Optionally, in one embodiment, such as Figure 1 and Figure 3 As shown, the telescopic shield assembly has bracket connecting mechanisms 6 at both ends perpendicular to its direction of movement. The first fixed brackets 3 and bracket connecting mechanisms 6 are correspondingly mounted on the outer protective component 2. When the telescopic shield assembly is closed, the bracket connecting mechanisms 6 at both ends of the telescopic shield assembly connect to the two first fixed brackets 3 respectively, thereby positioning the second side of the telescopic shield assembly on the outer protective component 2 from both sides. This enhances the positioning effect and ensures that the second side of the telescopic shield assembly facing the outer protective component 2 is tightly pressed against the outer protective component 2, thus ensuring a sealing and protective effect.

[0053] Optionally, in one embodiment, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the automatic switch structure of the protective cover also includes a crossbeam connecting mechanism 7 and a second fixed bracket 8; the crossbeam connecting mechanism 7 is located on the second side of the telescopic protective cover assembly, and the second fixed bracket 8 is located on the crossbeam assembly 1; when the telescopic protective cover assembly performs the opening action, the first drive mechanism drives the crossbeam assembly 1 to move toward the outer protective component 2, and the crossbeam connecting mechanism 7 connects to the second fixed bracket 8; when the telescopic protective cover assembly performs the closing action, the crossbeam connecting mechanism 7 is disconnected from the second fixed bracket 8.

[0054] When the telescopic shield assembly switches from the closed state to the open state, the first drive mechanism drives the crossbeam assembly 1 to move towards the outer protective component 2, so that the crossbeam assembly 1 is close to the second side of the telescopic shield assembly. At the same time, it drives the second fixed bracket 8 to move closer to the second side of the telescopic shield assembly and compresses the telescopic shield assembly to its shortest state. The crossbeam connecting mechanism 7 connects to the second fixed bracket 8 so that the second side of the telescopic shield assembly and the crossbeam assembly 1 remain relatively fixed. The bracket connecting mechanism 6 disconnects from the first fixed bracket 3. The first drive mechanism then drives the crossbeam assembly 1 to move away from the outer protective component 2. During this process, the telescopic shield assembly is compressed to its shortest state. The crossbeam assembly 1 can be fully opened by moving a small distance away from the outer protective component 2. This helps to reduce the stroke of the crossbeam assembly 1 and the first drive mechanism and reduce space occupation.

[0055] Optionally, in one embodiment, the crossbeam connecting mechanism 7 includes a crossbeam clamping drive mechanism; when the telescopic shield assembly performs an opening action, the clamping end of the crossbeam clamping drive mechanism clamps the second fixed bracket 8; when the telescopic shield assembly performs a closing action, the clamping end of the crossbeam clamping drive mechanism opens to release the second fixed bracket 8. The crossbeam clamping drive mechanism securely fixes the second side of the telescopic shield assembly to the second fixed bracket 8 by clamping, thereby facilitating the subsequent movement of the first drive mechanism away from the outer protective component 2 to open the telescopic shield assembly.

[0056] Optionally, in one embodiment, the beam clamping drive mechanism includes a beam clamping cylinder; the beam clamping cylinder is horizontally extended and fixed on the telescopic cover assembly, and the second fixed bracket 8 includes a second abutment plate 801, which extends vertically and is disposed toward the telescopic cover assembly. When the telescopic cover assembly performs an opening action, the clamping end of the beam clamping cylinder is engaged with the second abutment plate 801; when the telescopic cover assembly performs a closing action, the clamping end of the beam clamping cylinder opens to disengage from the second abutment plate 801. The beam clamping cylinder has a simple structure, occupies little space, and is easy to install.

[0057] Specifically, in this embodiment, such as Figure 2 and Figure 4 As shown, the second fixed bracket 8 is U-shaped. The second fixed bracket 8 includes a connecting plate and a crossbeam mounting plate and a second abutment plate 801 vertically arranged at both ends of the connecting plate. The crossbeam mounting plate is fixed on the crossbeam assembly 1, and the second abutment plate 801 is arranged opposite to the crossbeam mounting plate.

[0058] Optionally, such as Figure 1 and Figure 3As shown, the telescopic shield assembly has crossbeam connecting mechanisms 7 at both ends perpendicular to its direction of movement, and the second fixed brackets 8 are correspondingly arranged on the crossbeam assembly 1. The first drive mechanism drives the crossbeam assembly 1 to move closer to the outer protective component 2, and the two crossbeam connecting mechanisms 7 simultaneously connect the two second fixed brackets 8 from both sides to effectively compress the telescopic shield assembly and keep the telescopic shield assembly at a fixed length.

[0059] In other embodiments, the beam clamping drive mechanism may also include any clamping drive mechanism with two jaws. In this case, the second fixed bracket 8 is provided with a second snap-fit ​​hole, and the two jaws of the clamping drive mechanism are clamped and fixed on the second snap-fit ​​hole so that the beam drive mechanism and the second fixed bracket 8 remain relatively fixed.

[0060] In other embodiments, the beam connecting mechanism 7 may further include a second electromagnet, and the corresponding second fixed bracket 8 is made of ferromagnetic material. When it is necessary to connect the second fixed bracket 8, the second electromagnet is energized to firmly attract the second fixed bracket 8, so as to fix the second side of the telescopic cover assembly on the second fixed bracket 8; when it is necessary to disconnect the beam connecting mechanism 7 from the second fixed bracket 8, the second electromagnet is de-energized and can move away from the second fixed bracket 8.

[0061] Optionally, in one embodiment, the telescopic shield assembly includes a telescopic shield 501, a first end plate 502, and a second end plate 503. The first end plate 502 and the second end plate 503 are respectively disposed at both ends of the telescopic shield 501. The first end plate 502 is disposed on the crossbeam assembly 1, and the second end plate 503 is adapted to abut against the outer protective component 2. The bracket connecting mechanism 6 and the crossbeam connecting mechanism 7 are both connected to the second end plate 503 to fix the bracket connecting mechanism 6 and the crossbeam connecting mechanism 7 on the second side of the telescopic shield 501. The first end plate 502 is fixed on the crossbeam assembly 1 to fix the first side of the telescopic shield 501 on the crossbeam assembly 1. The second end plate 503 is adapted to abut against the outer protective component 2 to form a closed structure with the outer protective component 2 when the telescopic shield 501 performs a closing action.

[0062] Optionally, the telescopic shield assembly also includes two side plates 504, one side of each side plate 504 being fixed to both sides of the second end plate 503. The two side plates 504 are arranged opposite each other on both sides of the telescopic shield 501, facilitating the fixing of the bracket connecting mechanism 6 and the crossbeam connecting mechanism 7 via the side plates 504.

[0063] Specifically, in this embodiment, such as Figure 2 and Figure 4As shown, the side plate 504 is U-shaped, with one side fixed to the second end plate 503 and the other side extending towards the side of the telescopic cover 501. The automatic switch structure of the cover also includes a first mounting bracket 9 and a second mounting bracket 10. Both the first mounting bracket 9 and the second mounting bracket 10 are fixed to the side plate 504. The bracket clamping cylinder is fixed to the first mounting bracket 9, and the crossbeam clamping cylinder is fixed to the second mounting bracket 10. Both the bracket clamping cylinder and the crossbeam clamping cylinder extend horizontally, with their clamping ends facing away from each other, and they are spaced vertically apart. For example, optionally, the bracket clamping cylinder is located above the crossbeam clamping cylinder.

[0064] In one embodiment, the first drive mechanism includes a motor 401 and a lead screw drive mechanism 402. The crossbeam assembly 1 has a frame-like structure, and the motor 401 is connected to the lead screw drive mechanism 402, which is connected to the side of the crossbeam assembly 1 facing away from the outer protective member 2. The rotation of the motor 401 drives the crossbeam assembly 1 to move horizontally. The second fixed bracket 8 and the first end plate 502 are fixed to the side of the crossbeam assembly 1 facing the outer protective member 2.

[0065] According to an embodiment of the present invention, another aspect provides a processing device, including a frame, an outer protective component 2, and the aforementioned automatic cover switching structure.

[0066] The outer protective component 2 is located at the first end of the frame; the crossbeam assembly 1 is movably located on the frame.

[0067] In this processing equipment, the bracket connecting mechanism 6, in conjunction with the first drive mechanism, controls the closing or opening of the telescopic protective cover assembly. The bracket connecting mechanism 6 is located on the second side of the telescopic protective cover assembly, and its small footprint and convenient arrangement make it easy to arrange. Furthermore, when closing the telescopic protective cover assembly, the bracket connecting mechanism 6 has a small stroke, further reducing its footprint. During the closing or opening process of the telescopic protective cover assembly, it can effectively prevent jamming during the opening and closing of the telescopic protective cover assembly, thereby effectively reducing the failure rate of the processing equipment and improving production efficiency and maintenance costs.
