Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a protective mechanism for CNC machine tools. Background Technology

[0002] CNC machine tools are the core equipment in the field of modern machining. They integrate computer technology, automation control technology, precision measurement technology and other advanced technologies. Through pre-programmed instructions, CNC machine tools can accurately control the movement trajectory, speed and machining parameters of the machine tool, and achieve high-precision machining of various workpieces. They can process complex shapes and high-precision parts, and are widely used in many industrial fields such as aerospace, automobile manufacturing, mold processing and so on.

[0003] Existing technologies, such as the utility model patent with publication number CN214642188U, disclose a protective mechanism for CNC machine tools. This patent employs a protective box, with a fixing plate fixed to the box body on one side of the front face. An operation panel is mounted on the fixing plate. Upper and lower guide rails are respectively located at the upper and lower ends of the front face away from the fixing plate, with multiple protective doors between them. A dust removal device is located on the rear face of the protective box, passing through the rear face. The dust removal device includes a dust bag and a fan, with one end of the dust bag fitted onto the fan. On the machine, the protective box is equipped with a light at the top, and both sides of the protective box are equipped with protective plates that are hinged to the protective box. A fixing device is provided between one side of the protective plate and the protective box body. The protective mechanism for CNC machine tools of this utility model can be moved and used for different CNC machine tools. The protective door and viewing window can be used to observe the processing status inside the device at any time. It solves the problem that the existing protective covers for CNC machine tools are generally fixed around the worktable and are not easy to move. During the operation of the CNC machine tool, the worktable is blocked by the protective cover, and it is difficult for CNC operators to see the processing status of the CNC machine tool on the workpiece.

[0004] In the process of protecting CNC machine tools with protective mechanisms, there is a problem that existing protective mechanisms, such as those mentioned above, have side baffles that are hinged and installed on the main body surface. When the operator moves the protective mechanism toward the CNC machine tool, the baffles connected by the hinges will rotate under the action of external force, easily close again, and block the unfolded part, thus interfering with the operator's ability to move the protective mechanism toward the CNC machine tool. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where hinged baffles can rotate under external force, easily re-close, and obstruct the unfolded part, thus interfering with the operator's ability to move the protective mechanism toward the CNC machine tool. Therefore, this invention proposes a protective mechanism for CNC machine tools.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a protective mechanism for CNC machine tools, comprising a housing and a cover plate, the cover plate being installed on the upper surface of the housing, rollers being installed on the lower surface of the housing, a side sealing assembly being provided on the side surface of the housing, the side sealing assembly comprising a side baffle, the side baffle being disposed on the side surface of the housing, a mounting bracket being fixedly connected to the side of the side baffle near the housing, a positioning pin being slidably connected to the inner wall of the mounting bracket, a connecting bracket being fixedly connected to the side of the positioning pin away from the mounting bracket, a connecting arm being rotatably connected to the surface of the connecting bracket, a linkage bracket being rotatably connected to the end of the connecting arm away from the connecting bracket, a guide bracket being fixedly connected to the side surface of the side baffle, and an adjustment bracket being rotatably connected to the inner wall of the guide bracket.

[0007] Preferably, the side baffle has a guide hole on its surface, and the connecting frame is slidably connected to the inner wall of the guide hole. The guide hole can guide the movement direction of the connecting frame to ensure the stability of the connecting frame in the moving state.

[0008] Preferably, there are two mounting brackets, which are arranged symmetrically about the side baffle. The mounting brackets are in contact with the inner wall of the housing. The surface of the housing has an insertion hole. The positioning pin passes through the side surface of the mounting bracket and is inserted into the inner wall of the insertion hole. The position of the side baffle is locked by the cooperation of the mounting bracket and the locking pin in the locked state.

[0009] Preferably, the linkage frame and the guide frame are slidably connected on the surface, and the adjustment frame is threadedly connected to the inner wall of the linkage frame. Through the cooperation of the linkage frame and the connecting arm, the surrounding connecting frames can be moved synchronously.

[0010] Preferably, the surface of the outer shell is further provided with a sealing assembly, the sealing assembly including a U-shaped block, the U-shaped block being fixedly connected to the surface of the outer shell, a crossbar being fixedly connected to the side surface of the U-shaped block, a connecting frame being slidably connected to the surface of the crossbar, a baffle plate being fixedly connected to the surface of the connecting frame, a glass plate being fixedly connected to the inside of the baffle plate, and a handle being fixedly connected to the surface of the baffle plate. The movement direction of the baffle plate can be guided by the cooperation of the crossbar and the connecting frame.

[0011] Preferably, a guide rail is fixedly connected to the surface of the outer shell, and a sliding groove is provided on the side of the baffle plate near the outer shell. The guide rail is slidably connected to the inner wall of the sliding groove. Through the cooperation of the guide rail and the sliding groove, the crossbar can be used to support the position of the baffle plate.

[0012] Preferably, the connecting frame is in contact with the surface of the outer shell, and the baffle plate is in contact with the surface of the outer shell. Through the cooperation of the baffle plate and the glass plate, the opening of the outer shell can be blocked.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a side sealing component, when it is necessary to protect the CNC machine tool, ensure that the side sealing component is not installed, push the outer shell, and under the action of the rollers, the outer shell will be forced to move the cover plate above the CNC machine tool and cover the CNC machine tool. After the outer shell completely covers the CNC machine tool, remove the side baffle and place it against the side of the outer shell, align the positioning pin with the insertion hole, and rotate the adjusting frame clockwise. The adjusting frame and the linkage frame will engage. Under the guidance of the guide frame, the linkage frame will be pushed towards the side baffle by the adjusting frame. While the linkage frame is moving, it will cooperate with the connecting arm to push the connecting frame, and the connecting frame will be pushed by force. The locating pin, guided by the mounting bracket, is inserted into the socket. When the linkage frame contacts the surface of the side baffle, the locating pin is fully inserted into the socket and, together with the mounting bracket, locks the side baffle to the side of the housing. This allows the housing to completely cover the CNC machine tool from all sides. By setting the side sealing component, it is not only convenient for workers to assemble the protective mechanism, but also allows the protective mechanism to be quickly pushed onto the CNC machine tool. This reduces the problem of the baffle easily closing under external force when using hinge connections, which interferes with the installation of the protective mechanism, and further improves the smoothness of the installation process.

[0015] 2. In this utility model, by setting a sealing component, when it is necessary to retrieve a workpiece from inside the CNC machine tool through the protective mechanism, the handle is pulled away from the side sealing component. The handle pushes the baffle plate, and the baffle plate pushes the connecting frame. Under the guidance of the crossbar, the connecting frame, in conjunction with the guide rail and slide groove, guides the movement direction of the baffle plate. When the baffle plate moves, it causes the glass plate to shift. When the baffle plate moves to the maximum distance, the opening on the surface of the outer shell will be exposed, and the operator can then retrieve the workpiece through the opening. When a new workpiece is placed for processing, the baffle plate can be closed by reversing the above steps to re-close the outer shell. At the same time, during the processing of the equipment, the operator can observe the processing status of the equipment through the glass plate. By setting a sealing component, the protective effect of the protective mechanism is ensured while allowing the operator to open the protective mechanism to retrieve the workpiece.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a protective mechanism for CNC machine tools, including a housing 1 and a cover plate 2. The cover plate 2 is installed on the upper surface of the housing 1, a roller 3 is installed on the lower surface of the housing 1, a side sealing component 4 is provided on the side surface of the housing 1, and a sealing component 5 is also provided on the surface of the housing 1.

[0025] The specific settings and functions of the side sealing component 4 and the sealing component 5 will be explained in detail below.

[0026] In this embodiment: the side sealing assembly 4 includes a side baffle 41, which is disposed on the side surface of the housing 1. A mounting bracket 42 is fixedly connected to the side of the side baffle 41 near the housing 1. A positioning pin 43 is slidably connected to the inner wall of the mounting bracket 42. A connecting bracket 44 is fixedly connected to the side of the positioning pin 43 away from the mounting bracket 42. A connecting arm 45 is rotatably connected to the surface of the connecting bracket 44. A linkage bracket 46 is rotatably connected to the end of the connecting arm 45 away from the connecting bracket 44. A guide bracket 47 is fixedly connected to the side surface of the side baffle 41. An adjustment bracket 48 is rotatably connected to the inner wall of the guide bracket 47.

[0027] Specifically, the side baffle 41 has a guide hole 49 on its surface. The connecting frame 44 is slidably connected to the inner wall of the guide hole 49. The moving direction of the connecting frame 44 can be guided through the guide hole 49 to ensure the stability of the connecting frame 44 in the moving state.

[0028] Specifically, there are two mounting brackets 42, which are arranged symmetrically about the side baffle 41. The mounting brackets 42 are in contact with the inner wall of the outer shell 1. The surface of the outer shell 1 is provided with insertion holes. The positioning pin 43 passes through the side surface of the mounting bracket 42 and is inserted into the inner wall of the insertion hole.

[0029] In this embodiment: the position of the opposite side baffle 41 is locked by the cooperation of the mounting bracket 42 and the locking pin in the locked state.

[0030] Specifically, the linkage frame 46 and the guide frame 47 are slidably connected on their surfaces, and the adjustment frame 48 is threadedly connected to the inner wall of the linkage frame 46. Through the cooperation of the linkage frame 46 and the connecting arm 45, the surrounding connecting frames 44 can be moved synchronously.

[0031] In this embodiment: the sealing component 5 includes a U-shaped block 51, which is fixedly connected to the surface of the outer shell 1. A crossbar 52 is fixedly connected to the side surface of the U-shaped block 51. A connecting frame 53 is slidably connected to the surface of the crossbar 52. A baffle plate 54 is fixedly connected to the surface of the connecting frame 53. A glass plate 55 is fixedly connected to the inside of the baffle plate 54. A handle 56 is fixedly connected to the surface of the baffle plate 54.

[0032] In this embodiment, the movement direction of the baffle plate 54 can be guided by the cooperation between the crossbar 52 and the connecting frame 53.

[0033] Specifically, a guide rail 57 is fixedly connected to the surface of the outer shell 1, and a groove 58 is provided on the side of the baffle plate 54 near the outer shell 1. The guide rail 57 is slidably connected to the inner wall of the groove 58. Through the cooperation of the guide rail 57 and the groove 58, the crossbar 52 can be used to support the position of the baffle plate 54.

[0034] Specifically, the connecting frame 53 is in contact with the surface of the outer casing 1, and the shield 54 shown is in contact with the surface of the outer casing 1.

[0035] In this embodiment, the opening of the outer casing 1 can be blocked by the cooperation of the shielding plate 54 and the glass plate 55.

[0036] Working principle: When protecting a CNC machine tool, ensure that the side sealing assembly 4 is not installed, push the outer shell 1. Under the action of the roller 3, the outer shell 1 is forced to move the cover plate 2 above the CNC machine tool, thus shielding it. After the outer shell 1 completely covers the CNC machine tool, remove the side baffle 41 and place it against the side of the outer shell 1. Align the positioning pin 43 with the insertion hole, and rotate the adjusting frame 48 clockwise. The adjusting frame 48 engages with the linkage frame 46. Guided by the guide frame 47, the linkage frame 46 is pushed towards the side baffle 41 by the adjusting frame 48. While moving, the linkage frame 46, in conjunction with the connecting arm 45, pushes the connecting frame 44. The connecting frame 44 is pushed by the force. The positioning pin 43 is inserted into the socket under the guidance of the mounting bracket 42. When the linkage bracket 46 comes into contact with the surface of the side baffle 41, the positioning pin 43 is fully inserted into the socket and, together with the mounting bracket 42, locks the side baffle 41 to the side of the housing 1. This allows the housing 1 to completely cover the CNC machine tool. By setting the side sealing component 4, it is convenient for workers to assemble the protective mechanism and allows the protective mechanism to be quickly pushed onto the CNC machine tool. This reduces the problem that the baffle is easy to close again under external force when using hinge connection, which interferes with the installation of the protective mechanism and further improves the smoothness of the installation process of the protective mechanism.

[0037] Additionally, when retrieving workpieces from inside the CNC machine tool through the protective mechanism, pull the handle 56 away from the side sealing assembly 4. The handle 56 pushes the baffle 54, which in turn pushes the connecting frame 53. Guided by the crossbar 52, the connecting frame 53, in conjunction with the guide rail 57 and the slide groove 58, guides the movement of the baffle 54. As the baffle 54 moves, it causes the glass plate 55 to shift. When the baffle 54 reaches its maximum distance, the opening on the surface of the outer shell 1 will be exposed, allowing the operator to retrieve the workpiece through the opening. To retrieve a new workpiece and place it for processing, reverse the above steps to close the baffle 54 and re-close the outer shell 1. During the processing, the operator can observe the processing status of the equipment through the glass plate 55. By setting the sealing assembly 5, the protective effect of the protective mechanism is ensured while allowing the operator to open the protective mechanism to retrieve the workpiece.
