Description

Technical Field

[0001] This utility model relates to the field of machine tool protection technology, and more specifically, to a door opening and closing structure and a protective component. Background Technology

[0002] In modern manufacturing, precision measuring probes are widely used in various processing equipment, such as CNC machine tools, to inspect the dimensional and positional accuracy of workpieces. These probes require precise operation when performing measurement tasks, and when not in use, they often need a protective enclosure to protect them from external environmental interference, such as cutting fluid, cooling water, and dust.

[0003] Existing probe protection components mainly adopt a sliding or rotating door structure to achieve probe switching and protection.

[0004] Sliding door safety components typically require sufficient space to be reserved on both sides or above the machine tool for door movement. This structural design means that even when the door is closed, some space must be provided to ensure smooth door movement.

[0005] While revolving door safety components reduce horizontal space requirements to some extent, the space constraints within their rotation radius and vertical space requirements remain significant. The distance from the axis of the revolving door to the farthest point of the door body, i.e., the rotation radius, must be reserved inside the machine tool, which also occupies space in three-dimensional space.

[0006] Whether it's a sliding door or a revolving door protective assembly, its original design purpose is to protect the probe from interference from external environmental factors such as cutting fluid, cooling water, and dust. However, in practical applications, the space occupied by this traditional protective mechanism limits the flexibility of the machine tool's internal layout and affects the overall performance of the processing equipment.

A first waterproof pad is provided at intervals on the outer side of the first protective door, and a second waterproof pad is provided on the outer side of the second protective door. The second waterproof pad is sealed with the second protective door on the side closest to the first protective door. A detection channel is formed between the first waterproof pad and the second waterproof pad along the direction from the first side to the second side of the detection port.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0048] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" are generally used in relation to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0049] See also Figures 1 to 10As shown, according to an embodiment of the present invention, the door opening and closing structure includes: a protective frame 1, the protective frame 1 having a detection port 2; a first protective door 3, which is rotatably disposed on a first side 4 of the detection port 2 and has a closed position and an outwardly rotatable open position; a second protective door 5, which is rotatably disposed on a second side 6 of the detection port 2 and has a closed position and an outwardly rotatable open position, wherein the first side 4 and the second side 6 are opposite to each other; a return device 7, disposed between the first protective door 3 and the protective frame 1 and the second protective door 5 and the protective frame 1, and capable of providing a return force for the first protective door 3 and the second protective door 5 to return to the closed position; when both the first protective door 3 and the second protective door 5 are in the closed position, the first protective door 3 and the second protective door 5 are stacked, and in the stacked position, the first protective door 3 is located outside the second protective door 5.

[0050] In this embodiment, the opening and closing structure is provided with a first protective door 3 and a second protective door 5 at the detection port 2 of the protective frame 1. The first protective door 3 and the second protective door 5 are flipped to open and close the detection port 2. The first protective door 3 and the second protective door 5 work together to control the opening and closing of the detection port 2. This significantly reduces the flipping radius of the first protective door 3 and the second protective door 5 compared to a single-door flipping structure, and greatly reduces the space required for the first protective door 3 and the second protective door 5 to flip. Therefore, it can significantly reduce the activity space required for the first protective door 3 and the second protective door 5 to open or close the detection port 2, save the internal activity space required for the opening and closing structure, improve the layout flexibility of the opening and closing structure, and make the overall structure of the opening and closing structure more compact and smaller in size.

[0051] The first protective door 3 and the second protective door 5 are stacked, and in the stacked position, the first protective door 3 is located outside the second protective door 5. In the closed state, the first protective door 3 and the second protective door 5 can be stacked, which can enhance the sealing effect of the first protective door 3 and the second protective door 5, and more effectively prevent liquids such as cutting fluid and cooling water from entering the detection port 2. This provides more effective protection for components such as probes in the opening and closing structure and extends the service life of the probes.

[0052] In one embodiment, the first side is the upper side of the detection port 2, and the second side is the lower side of the detection port 2. That is, the first protective door 3 is disposed on the upper side of the detection port 2, and the second protective door 5 is disposed on the lower side of the detection port 2. When the first protective door 3 and the second protective door 5 are stacked, since the first protective door 3 is located outside the second protective door 5, it can form a stronger blocking effect on cutting fluid and coolant, and play a better protective role.

[0053] See also Figure 1 and Figure 2As shown, in one embodiment, the first protective door 3 and the second protective door 5 are sealed together in the stacked position. This sealed fit between the first protective door 3 and the second protective door 5 further enhances their protective effect when closed, more effectively preventing liquids such as cutting fluid and coolant from entering the internal space through the gap between the first protective door 3 and the second protective door 5, thus providing a more effective protection for the probe.

[0054] The sealing fit between the first protective door 3 and the second protective door 5 can be a close fit between the first protective door 3 and the second protective door 5. When the first protective door 3 and the second protective door 5 are in the closed position, they can form a certain abutting action under the return action of the return device 7. This abutting action can make the inner surface of the first protective door 3 and the outer surface of the second protective door 5 form a good fit effect, thereby ensuring the sealing fit effect.

[0055] In one embodiment, to ensure the accuracy of the first protective door 3 and the second protective door 5 in the closed position, a stop can be provided on the inner side of the first protective door 3 and the second protective door 5. When the first protective door 3 and the second protective door 5 return to the closed position under the action of the return device 7, the stop can be stopped by the stop, so that the first protective door 3 and the second protective door 5 stop accurately in the closed position. The stop can be, for example, a stop block or a stop pin. The stop can be integrally formed with the protective frame 1 or can be detachably installed on the protective frame 1.

[0056] In one embodiment, the first protective door 3 is provided with a first sealing gasket 8 on one side of the stacked structure, and the first sealing gasket 8 is located on the side of the first protective door 3 facing the second protective door 5.

[0057] In one embodiment, the second protective door 5 is provided with a first sealing gasket 8 on one side of the stacked structure, and the first sealing gasket 8 is located on the side of the second protective door 5 facing the first protective door 3.

[0058] In one embodiment, the first protective door 3 and the second protective door 5 are provided with a first sealing gasket 8 on one side of their stacking. The first sealing gasket 8 is located on the side of the first protective door 3 facing the second protective door 5, and the second protective door 5 is located on the side of the first protective door 3 facing the first protective door 3.

[0059] In one embodiment, the first sealing gasket 8 has a U-shaped cross-section and is fitted onto the side of the second protective door 5 away from the flip axis.

[0060] In one embodiment, the first sealing gasket 8 is, for example, a sealing strip or a rubber gasket. The first sealing gasket 8 extends along the side of the second protective door 5 away from the flip axis, and the extension length is equal to the length of the side of the second protective door 5 away from the flip axis, thereby ensuring the sealing effect between the first protective door 3 and the second protective door 5. Since the second protective door 5 is located inside the first protective door 3, placing the first sealing gasket 8 on the second protective door 5 allows the first protective door 3 to provide a certain degree of protection for the first sealing gasket 8, reducing the aging rate of the first sealing gasket 8 and extending its service life.

[0061] In one embodiment, the first sealing gasket 8 is disposed on the side of the first protective door 3 facing the second protective door 5, and is fixed to the inner sidewall of the first sealing gasket 8 by adhesive.

[0062] See also Figures 1 to 4 As shown, in one embodiment, a first impact block 9 is provided on the inner side of the first protective door 3, and a second impact block 10 is provided on the inner side of the second protective door 5. Both the first impact block 9 and the second impact block 10 are located outside the stacked area.

[0063] In this embodiment, by providing a first impact block 9 on the inner side of the first protective door 3 and a second impact block 10 on the inner side of the second protective door 5, the first and second impact blocks 9 and 10 can cooperate with the probe top block 34 of the probe detection assembly to control the closing sequence of the first and second protective doors 3 and 5, thus more effectively ensuring the smooth closing of the first and second protective doors 3 and 5. Furthermore, by providing the first and second impact blocks 9 and 10, the action of the probe top block 34 acts on the first and second impact blocks 9 and 10, rather than directly on the first and second protective doors 3 and 5, thus also providing protection for the first and second protective doors 3 and 5.

[0064] In one embodiment, the heads of the first impact block 9 and the second impact block 10 are staggered in the direction of the flipping axis of the first protective door 3.

[0065] In this embodiment, both the first impact block 9 and the second impact block 10 include a head and a connecting part. The head is connected to the first protective door 3 or the second protective door 5 through the connecting part, and the heads are staggered in the horizontal direction. This structural arrangement ensures that the first protective door 3 and the second protective door 5 will not interfere with each other during opening or closing when they are close to each other due to the ejection action of the probe top block 34. It also allows for a smaller horizontal distance between the first impact block 9 and the second impact block 10, resulting in less space occupation. This facilitates the arrangement of the first impact block 9 and the second impact block 10 in a small space and avoids interference problems caused by excessive proximity. Through the above design, the opening and closing door structure can be made smaller, saving internal space of the protective components, while still ensuring the inspection and processing of workpieces of different sizes, making full use of the structural space and eliminating the space cost of component stacking.

[0066] In one embodiment, when both the first protective door 3 and the second protective door 5 are in the closed position, the protrusion height of the first impact block 9 is higher than that of the second impact block 10 in the direction from the outside to the inside. That is, the distance between the top of the first impact block 9 and the inner side of the first protective door 3 is greater than the distance between the top of the second impact block 10 and the inner side of the first protective door 3.

[0067] In this embodiment, by limiting the relationship between the protrusion heights of the first impact block 9 and the second impact block 10, the contact sequence between the first impact block 9 and the second impact block 10 and the probe top block 34 can be controlled, thereby controlling the opening or closing sequence of the first protective door 3 and the second protective door 5, and realizing the orderly opening and closing of the first protective door 3 and the second protective door 5.

[0068] When it is necessary to open the first protective door 3 and the second protective door 5, the probe top block 34 pushes outward. During the pushing process, since the protrusion height of the first impact block 9 is higher than that of the second impact block 10, the probe top block 34 first contacts the first impact block 9 and pushes the first impact block 9 to move outward. Under the action of the first impact block 9, the first protective door 3 begins to flip outward. At this time, since the probe top block 34 has not yet contacted the second impact block 10, the second protective door 5 is still in the closed position.

[0069] The probe top block 34 continues to extend outward and reaches the position where it contacts the second impact block 10. At this point, under the pushing action of the probe top block 34, the second impact block 10 causes the second protective door 5 to flip outward, and the second protective door 5 begins to open. When the opening of the first protective door 3 and the second protective door 5 is large enough to allow the probe top block 34 to extend, the first protective door 3 and the second protective door 5 remain in that position, and the probe top block 34 continues to extend outward to the detection position, and the detection probe begins to work.

[0070] When the detection probe completes the detection action and needs to retract, the movement process of the probe top block 34, the first protective door 3 and the second protective door 5 is opposite to the extension process, so that the second protective door 5 reaches the closed position first, and then the first protective door 3 reaches the closed position, forming a seal on the outside of the second protective door 5.

[0071] In one embodiment, the end face of the first impact block 9 and the second impact block 10 away from the first protective door 3 is a convex arc surface 11.

[0072] When the probe detection assembly extends or retracts, the probe top block 34 contacts the convex arc surface 11 of the first impact block 9 or the second impact block 10. Guided by the convex arc surface 11, the probe top block 34 can smoothly push the impact block, thereby controlling the sequential opening and closing of the first protective door 3 and the second protective door 5. This avoids the impact and damage that may be caused by hard contact, ensuring the smooth operation of the probe detection assembly while also maintaining the long-term reliability and quiet operation of the protective assembly.

[0073] In one embodiment, the head of the probe top block 34 is also a convex arc surface, which can form a smoother fit with the convex arc surface 11 of the first impact block 9 and the second impact block 10, thereby reducing motion resistance and wear.

[0074] In one embodiment, the first protective door 3 and the second protective door 5 are respectively provided with folded edges on both sides in the horizontal direction. The folded edges can be used to form a stop structure on both sides of the first protective door 3 and the second protective door 5 in the horizontal direction. Waterproof cutting fluid or coolant can enter the inner side of the opening and closing door structure from both sides of the first protective door 3 and the second protective door 5, thereby further improving the protective capability of the opening and closing door structure.

[0075] In one embodiment, a water-blocking door frame 12 is provided inside the protective frame 1. The water-blocking door frame 12 is arranged around the outer periphery of the first impact block 9 and the second impact block 10. When the first protective door 3 and the second protective door 5 are both in the closed position, the side of the water-blocking door frame 12 facing the first protective door 3 and the second protective door 5 is sealed to the inner side of the first protective door 3 and the second protective door 5.

[0076] In this embodiment, the annular design of the water-blocking door frame 12 surrounds the outer periphery of the first impact block 9 and the second impact block 10 and is integrated with the internal structure of the protective frame 1. When the first protective door 3 and the second protective door 5 are closed to the closed position, the water-blocking door frame 12 forms a sealed fit with the inner side of the first protective door 3 and the second protective door 5. This effectively utilizes the relative displacement between the water-blocking door frame 12 and the first protective door 3 and the second protective door 5 during the movement of the door body. By tightly fitting together to form a waterproof barrier, the water tightness and anti-pollution ability of the protective components are significantly enhanced, ensuring that the probe detection components can maintain high precision and long-term stable operation even in harsh processing environments.

[0077] When the probe detection assembly moves, the smooth operation of the probe detection assembly is ensured by the dynamic contact and separation between the first impact block 9 and the second impact block 10 and the water-blocking gate frame 12. At the same time, the sealing surface of the water-blocking gate frame 12 and the gate body can form a gapless fit when the gate is closed, effectively preventing liquids such as coolant and cutting fluid from entering the working area of ​​the probe detection assembly, reducing equipment maintenance costs and improving overall processing quality and efficiency.

[0078] In one embodiment, a second sealing gasket 13 is provided on the side of the water-blocking gate frame 12 facing the first protective door 3 and the second protective door 5.

[0079] In one embodiment, the floodgate frame 12 includes a straight section and a conical section, wherein the larger end of the conical section faces the first protective door 3 and the second protective door 5, the straight section is connected to the side of the conical section away from the first protective door 3, and the second sealing section 13 is a U-shaped rubber strip, which is sleeved on the conical section. This structure can utilize the gradually expanding structure of the conical section to form an anti-detachment limit for the second sealing gasket 13, eliminating the need for other limiting structures, so that the second sealing gasket 13 can be stably held on the floodgate frame 12, and the overall structure is simpler.

[0080] In one embodiment, a third sealing gasket 14 is provided on the inner side of the first protective door 3 and the second protective door 5 facing the water-blocking door frame 12.

[0081] In this embodiment, a second sealing gasket 13 is provided on the side of the water-blocking door frame 12 facing the first protective door 3 and the second protective door 5, while a third sealing gasket 14 is provided on the inner side of the first protective door 3 and the second protective door 5 facing the water-blocking door frame 12. This double sealing design can significantly improve the waterproof performance during the opening and closing of the protective door, ensuring that even under extreme processing conditions, liquid cannot seep in through the gap between the door frame and the door body, thereby protecting the probe detection component from external liquid damage, maintaining its high-precision detection capability and extending its service life, while enhancing the sealing and durability of the entire protective component.

[0082] When the first protective door 3 and the second protective door 5 are closed, the second sealing gasket 13 and the third sealing gasket 14 fit tightly together, forming a multi-layered waterproof barrier. Even if the door body undergoes slight displacement due to impact or vibration, it can maintain an effective seal, preventing the penetration of liquids such as cutting fluid and cooling water, and providing good protection for the probe detection components.

[0083] In one embodiment, a first support 15 is provided on the first side 4 of the protective frame 1, and the first protective door 3 is installed on the first support 15 by a return device 7.

[0084] In this embodiment, the first side 4 of the protective frame 1 is equipped with a first support 15, and the first protective door 3 is connected to it through a return device 7, which ensures the stability of the first protective door 3 during the opening and closing process and the convenience of automatic reset. The first protective door 3 can quickly and accurately return to the closed position to prevent contaminants such as coolant and chips from entering the working area.

[0085] In one embodiment, a second support 16 is provided on the second side 6 of the protective frame 1, and the second protective door 5 is installed on the second support 16 by a return device 7.

[0086] In one embodiment, the first support 15 and the second support 16 adopt a hinge structure.

[0087] In one embodiment, a first waterproof pad 17 is provided at intervals on the outer side of the first protective door 3, and a second waterproof pad 18 is provided on the outer side of the second protective door 5. The second waterproof pad 18 seals the second protective door 5 on the side close to the first protective door 3. A detection channel is formed between the first waterproof pad 17 and the second waterproof pad 18 along the direction from the first side 4 to the second side 6 of the detection port 2.

[0088] In this embodiment, a first waterproof gasket 17 is installed on the outer side of the first protective door 3, while a second waterproof gasket 18 is installed on the outer side of the second protective door 5. On the side where the two doors meet, the second waterproof gasket 18 and the second protective door 5 form a seal. This structural arrangement further enhances the waterproofing effect of the outermost part of the door opening and closing structure by creating a waterproof structure on the outer side of the first and second protective doors 3. The seal between the second waterproof gasket 18 and the second protective door 5 on the side where the two doors meet effectively prevents cutting fluid or cooling water from entering between the second protective door 5 and the second waterproof gasket 18 through the gap between them, further improving the waterproofing effect of the outer side of the second protective door 5.

[0089] A detection channel is constructed between the first waterproof pad 17 and the second waterproof pad 18 along the detection port 2 from the first side 4 to the second side 6. The width of the detection channel is greater than the size required for the probe top block 34 to be ejected, so as to avoid the arrangement of the first waterproof pad 17 and the second waterproof pad 18 from hindering the operation of the probe detection assembly.

[0090] In one embodiment, the first waterproof pad 17 is disposed on the protective frame 1, and the second waterproof pad 18 is installed on the second protective door 5 via a pad block 19 on the side of the second protective door 3 closest to the first protective door 3.

[0091] In this embodiment, since the second protective door 5 is located on the lower side, when the second waterproof pad 18 and the second protective door 5 are spaced apart, a gap can easily form between them. Cutting fluid or cooling water can easily enter this gap, weakening the protective effect of the second waterproof pad 18. By providing a pad 19 on the side of the second waterproof pad 18 and the second protective door 5 closest to the first protective door 3, the pad 19 can create a liquid-blocking effect, preventing cutting fluid or cooling water from easily entering the gap between the second waterproof pad 18 and the second protective door 5.

[0092] In one embodiment, the second waterproof pad 18 is fixedly installed on the outer wall of the second protective door 5.

[0093] In this embodiment, the second waterproof pad 18 can be attached to the second protective door 5, thereby directly forming a waterproof effect on the outer wall of the second protective door 5.

[0094] In one embodiment, the return device 7 is, for example, an elastic hinge or a torsion spring.

[0095] See also Figures 5 to 8 As shown, according to an embodiment of the present invention, the protective component includes a housing 20 and a switch door structure disposed within the housing 20, wherein the switch door structure is the switch door structure described above.

[0096] In one embodiment, the housing 20 includes an outer frame 21 and a protective front door panel 22 disposed on the front side of the outer frame 21. The protective front door panel 22 is provided with a detection port 23, and the door opening and closing structure is provided corresponding to the detection port 23.

[0097] In this embodiment, the housing 20 consists of an outer frame 21 and a protective front door panel 22. The protective front door panel 22 is installed on the front side of the outer frame 21 and has a detection port 23. The opening and closing door structure is set to correspond to the detection port 23, so that when the probe detection component is performing workpiece inspection, it can accurately enter and exit through the detection port 23 on the protective front door panel 22 without having to fully open the front door panel. This effectively prevents coolant, chips, or other contaminants in the working environment from directly entering the housing through the detection port 23. In particular, when the first protective door 3 and the second protective door 5 are opened and closed, the position and size of the detection port 23 ensure that the probe detection component can move smoothly, while minimizing the opening area, improving protection efficiency, ensuring the accuracy and reliability of the internal equipment under various harsh conditions, optimizing the inspection process, and reducing maintenance costs.

[0098] In one embodiment, the protective front door panel 22 has a folded edge 24 on its edge. The protective front door panel 22 covers the front side of the outer frame 21 through the folded edge 24. The top of the protective front door panel 22 overlaps with the top of the outer frame 21. A water receiving trough 25 is provided in the outer frame 21 at the corresponding overlapping position. A drain pipe 26 is connected to the bottom of the water receiving trough 25.

[0099] In this embodiment, the protective front door panel 22 is designed with a folded edge 24. The folded edge structure can fit the outer frame 21 to a large extent, and the front door panel can be firmly covered on the front side of the outer frame 21. The overlap between the top of the front door panel and the top of the outer frame 21, combined with the water receiving groove 25 and the drain pipe 26 provided inside the outer frame 21, forms an effective waterproof and drainage mechanism. When liquids such as coolant or cutting fluid from the top of the outer frame 21 enter the outer frame 21 through the top gap, they will be guided into the water receiving groove 25 and finally discharged through the drain pipe 26. This improves the water tightness of the protective components and the corrosion resistance of the equipment, while reducing maintenance and cleaning work.

[0100] In one embodiment, the outer frame 21 has a side opening 27 on its side, a side protective door 28 is provided at the side opening 27, a downwardly extending guide slope 29 is provided at the top of the side opening 27, and a stacked slope 30 is provided at the top of the side protective door 28, which is stacked on the lower side of the guide slope 29.

[0101] In this embodiment, a side protective door 28 is installed at the side opening 27 on the side of the outer frame 21. The top of the side opening 27 is designed with a downwardly extending guide bevel 29, while the top of the side protective door 28 is provided with a stacked bevel 30. When the side protective door 28 is installed, the stacked bevel 30 is tightly overlapped below the guide bevel 29, effectively guiding and blocking liquid from entering the equipment along the side opening 27. The guiding effect of the bevel and the sealing effect of the stacked bevel complement each other, significantly enhancing the waterproof performance of the equipment.

[0102] In one embodiment, a sealing gasket 31 is provided around the side opening 27, and the side protective door 28 is pressed against the sealing gasket 31.

[0103] When installing the side protective door 28, the sealing gasket 31 can be installed first, and then the sealing gasket 31 can be pressed by the side protective door 28. After that, the side protective door 28 can be fixedly connected to the outer frame 21 by screws and other connectors, so as to achieve a good protective effect.

[0104] In one embodiment, an annular sealing groove can be formed on the outer frame 21 around the side opening 27, and a sealing gasket 31 is disposed in the sealing groove.

[0105] In one embodiment, the sealing gasket 31 can be directly attached to the outer frame 21 around the side opening 27.

[0106] In one embodiment, the housing 20 includes an outer frame 21, side protective doors 28, and a protective front door panel 22. The housing 20 has the outer frame 21 as its main structure, and the protective front door panel 22 and the side protective doors 28 are detachably connected to the outer frame 21 by screws, which makes the structural design of the housing 20 simple and convenient for disassembly and subsequent maintenance.

[0107] The outer frame 21 can be integrally formed. The outer frame 21 has a front opening for installing the protective front door panel 22, and a side opening 27 is provided on the side. When the protective front door panel 22 is installed on the outer frame 21 and the side protective door 28 is installed in the side opening 27, the housing 20 can form an integrated splicing structure, making the overall assembly structure simpler.

[0108] In one embodiment, a probe detection assembly is also provided inside the housing 20. The probe detection assembly is located inside the door structure and is corresponding to the door structure. The probe detection assembly includes a detection probe 32, a probe support 33, and a probe top block 34. The probe top block 34 and the detection probe 32 are fixedly connected to the probe support 33.

[0109] When the probe inspects the workpiece, the probe holder 33 moves forward under the action of driving force, so that the detection probe 32 and the probe top block 34 extend forward together. The power source that drives the probe holder 33 to extend can be a cylinder, motor, electric cylinder, etc.

[0110] In one embodiment, the detection probe 32 and the probe top block 34 are arranged side by side, and the detection probe 32 is located outside the first impact block 9 and the second impact block 10 in the horizontal direction, so that the detection probe 32 will not come into contact with the first impact block 9 and the second impact block 10 during the extension process, and the probe top block 34 can effectively protect the detection probe 32.

[0111] The following is combined Figures 9 to 10 The process of extending and retracting the probe detection component is explained.

[0112] 1. The probe detection component has a certain distance from the door opening and closing structure in the initial state.

[0113] 2. The probe detection assembly begins to move. Due to the different sizes of the first impact block 9 and the second impact block 10, the probe top block 34 contacts the first impact block 9 first during operation, thus ensuring that the first protective door 3 opens first. At this time, the second impact block 10 does not contact the probe top block 34.

[0114] 3. As the probe top block 34 continues to move, the probe top block 34 begins to contact the second impact block 10, and the second protective door 5 begins to open.

[0115] 4. When the second protective door 5 and the first protective door 3 are fully opened, the probe extends fully from the channel between the first protective door 3 and the second protective door 5, and the detection probe 32 begins to detect the dimensional accuracy of the workpiece to be processed.

[0116] 5. After the test is completed, the probe detection assembly retracts as a whole, and the probe top block 34 begins to retract, maintaining contact between the probe top block 34 and the first impact block 9 and the second impact block 10. Under the action of the spring force, the elastic hinge causes the first impact block 9 and the second impact block 10 to roll along the end arc surface of the probe top block 34, and the first protective door 3 and the second protective door 5 begin to close.

[0117] 6. As the probe top block 34 continues to retract, the probe top block 34 first loses contact with the second impact block 10, and the second protective door 5 closes first. At this time, the probe top block 34 remains in contact with the first impact block 9, and the first protective door 3 is not completely closed.

[0118] 7. As the probe top block 34 continues to retract, the first impact block 9 disengages from the probe top block 34, and the first protective door 3 is completely closed. The probe detection assembly returns to its initial position, and the detection is complete.
