Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool protection technology, and in particular to a protective device for a machine tool tool setting device, a tool setting device component, and a machine tool. Background Technology
[0002] During machine tool processing, the continuous frictional cutting between the cutting tool and the workpiece inevitably causes tool wear. Increased tool wear directly leads to a decrease in machining accuracy, making it difficult to meet the high-precision machining requirements of the workpiece. Therefore, to ensure that machine tool machining accuracy remains within acceptable limits, regular tool inspection and calibration are essential steps in the machine tool processing flow. The tool setting device is the core equipment for achieving accurate tool inspection and calibration.
[0003] However, in practical applications, tool setters are often subjected to harsh machining environments such as machine tool spray, chip splashes, continuous vibration, alternating light exposure, high and low temperature cycles, and humidity. These complex environmental factors continuously affect the tool setter, seriously threatening its stable operation and measurement accuracy. Therefore, designing scientific and reasonable protective measures for the tool setter is of irreplaceable importance in ensuring its stable working performance, accurate measurement, and extending its service life.
[0004] Currently, some machine tools lack adequate protection for their tool setters, leaving them directly exposed to harsh environments. Although the tool setters themselves have a high protection rating (generally IP67, some IP68), external sealing components are prone to aging and failure under prolonged use. Especially during spraying or when there is a large volume of chips, the impact of coolant and chips, as well as alternating high and low temperatures, will shorten the tool setter's lifespan and reduce measurement accuracy. Furthermore, these tool setters rely solely on air to clean the tool face; the fine chips remaining after the cutting fluid evaporates cannot be completely removed, still affecting measurement accuracy.
[0005] There are also tool setters with protective structures on the market, most of which are flip-top type, using a linkage mechanism to open and close the protective cover. However, the moving structure is complex, prone to wear and jamming, with high maintenance costs and insufficient protection reliability. Another type directly connects the tool setter body to the moving mechanism, using a single linear guide rail to guide and drive the cylinder. Due to the high and low temperature changes inside the machine tool, the guide rail expands and contracts with temperature changes, and the vibration of the cylinder movement is transmitted to the guide rail, both of which lead to a decrease in the guide rail's guiding accuracy. Furthermore, the impact vibration generated when the protective cover opens and the tool setter base is in place will further deteriorate the motion positioning accuracy of the tool setter, ultimately failing to meet the requirements of high-precision machining. Utility Model Content

It solves the problem in the prior art where the tool setting device mounting base is driven by linear guide rails and linear cylinders, and the motion accuracy of the guide rails and cylinders is unstable due to factors such as temperature, vibration, and air pressure fluctuations, resulting in poor motion positioning accuracy of the tool setting device. This invention effectively protects the tool setting device without introducing motion positioning errors, thus ensuring the original measurement accuracy of the tool setting device.

An opening is provided at the upper end of the protective housing, which communicates with the protective chamber. The tool setting mechanism of the tool setter is exposed outward from the opening. A protective cover is movably fitted onto the opening. The protective cover has a recessed clearance chamber on the side facing the protective housing, which is used to clear the tool setting mechanism. A drive mechanism, the output end of which is connected to the protective cover, is used to drive the protective cover to move up and down and rotate, so as to open or close the opening.
[0008] According to the present invention, a protective device for a machine tool tool setting device further includes a connecting block, which is connected between the drive mechanism and the protective cover and is located in the clearance chamber. The connecting block and the clearance chamber are conformally arranged to each other.
[0009] According to the present invention, a protective device for a machine tool tool setting device further includes a tool setting device base plate. One end of the tool setting device base plate is connected to the base, and the other end extends toward the opening. The tool setting device base plate is used to mount the tool setting device on the base. One end of the tool setting device base plate near the opening and the other end of the connecting block that cooperates with the tool setting device base plate when closed are provided with a positioning groove and a positioning block, respectively. The positioning groove and the positioning block cooperate with each other to position the closing direction of the protective cover.
[0010] According to the present invention, a protective device for a machine tool tool setting device is provided, wherein the positioning groove includes two opposing and outwardly inclined inner inclined surfaces, and the positioning block is provided with two outer inclined surfaces that match the inner inclined surfaces. The inner inclined surfaces and the outer inclined surfaces cooperate to guide the opening or closing of the protective housing.
[0011] According to the present invention, a protective device for a machine tool tool setting instrument is provided, wherein the end of the connecting block away from the tool setting instrument base plate is bent toward the base to form a connecting part, and the connecting part is connected to the protective cover by fasteners.
[0012] According to the present invention, a protective device for a machine tool tool setting device is provided, wherein the protective housing includes a first housing and a second housing, the first housing surrounds the outer side of the base and forms a side opening, and the second housing is detachably connected to the side opening.
[0013] According to the present invention, a protective device for a machine tool tool setter further includes a connecting component. The connecting component is connected between the base and the machine tool. The connecting component includes a connecting plate and a mounting plate. The connecting plate and the mounting plate are arranged at an angle to each other. One end of the connecting plate is connected to the machine tool, and the other end is connected to the mounting plate. The mounting plate is used to connect and fix to the base.
[0014] According to the present invention, a protective device for a machine tool tool setting instrument further includes a cleaning air nozzle, which is disposed in the protective chamber and located on the periphery of the tool setting instrument. The blowing direction of the cleaning air nozzle is directed toward the tool setting mechanism of the tool setting instrument.

[0016] This utility model also provides a machine tool, including a protective device for the machine tool tool setting device as described above, or a tool setting device assembly as described above.
[0017] This utility model provides a protective device for a machine tool tool setting instrument. By fixing the tool setting instrument to the base and the machine tool, it prevents the tool setting instrument from participating in any movement, thus completely avoiding positioning offsets that may be caused by moving parts and fundamentally eliminating new motion positioning errors. The protective action is completed independently by the protective cover, and the tool setting mechanism always remains in a fixed position, preventing collisions or displacements caused by the movement of the protective cover, and is unaffected by vibrations and inertia of the drive mechanism. The avoidance chamber design ensures that the protective cover does not contact the tool setting mechanism when opening and closing, avoiding accuracy offsets caused by mechanical interference and fully preserving the original measurement accuracy of the tool setting instrument. In addition, the protective chamber can effectively isolate the tool setting instrument from corrosion by chips, coolant, and moisture, preventing aging of the tool setting instrument's seals and contamination of the tool setting surface. When the protective cover is closed, the opening is completely sealed, with the tool setting mechanism exposed only during testing, greatly reducing the impact of harsh environments on the equipment and achieving effective protection for the tool setting instrument.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0030] The following is combined with Figures 1 to 5The present invention provides a detailed description of a protective device for a machine tool tool setting device, a tool setting device component, and a machine tool through specific embodiments and application scenarios.
[0031] In the embodiments of this utility model, such as Figures 1 to 3 As shown, a protective device 1 for a machine tool tool setting device includes a base 10, a protective housing 20, a protective cover 30, and a drive mechanism 40. The base 10 is connected to the machine tool and is used to install the tool setting device 2. The protective housing 20 surrounds the outer periphery of the base 10, forming a protective chamber for accommodating the tool setting device 2. An opening 21 is provided at the upper end of the protective housing 20, which communicates with the protective chamber. The tool setting mechanism of the tool setting device 2 is exposed outward through the opening 21. The protective cover 30 is movably closed onto the opening 21. The protective cover 30 has an inward recess on the side facing the protective housing 20 to form a clearance chamber, which is used to avoid the tool setting mechanism. The output end of the drive mechanism 40 is connected to the protective cover 30, and the drive mechanism 40 is used to drive the protective cover 30 to move up and down and rotate to open or close the opening 21.
[0032] The base 10 is the basic component of the entire protective device. It is connected to the machine tool and provides a stable mounting platform for the tool setter 2. By fixing the tool setter 2 to the base 10, the stability of the tool setter 2 during operation is ensured, preventing it from participating in any movement. This avoids positioning offsets that may be caused by moving parts, fundamentally eliminating new motion positioning errors and ensuring the original measurement accuracy of the tool setter 2.
[0033] The protective housing 20 surrounds the outer periphery of the base 10, forming a protective chamber for housing the tool setter 2. This protective chamber effectively isolates corrosive factors such as chips and coolant from the machine tool processing environment, preventing aging of the seals of the tool setter 2 and contamination of the tool setting surface, thereby extending the service life of the tool setter 2 and ensuring its stable operation. The opening 21 at the upper end of the protective housing 20 communicates with the protective chamber, allowing the tool setting mechanism of the tool setter 2 to be exposed outward from the opening 21 for tool inspection and calibration operations.
[0034] The protective cover 30 movably covers the opening 21 at the upper end of the protective housing 20. When the protective cover 30 is closed, it completely seals the opening 21, further enhancing the sealing performance of the protective device, effectively isolating the tool setter 2 from the harsh external environment, reducing the impact of the harsh environment on the equipment, and achieving effective protection for the tool setter 2. A clearance chamber is recessed on the side of the protective cover 30 facing the protective housing 20. This clearance chamber is used to avoid contact between the protective cover 30 and the tool setter mechanism, ensuring no contact during the opening and closing of the cover 30, avoiding accuracy deviation caused by mechanical interference, fully preserving the original measurement accuracy of the tool setter 2, and also preventing damage to the tool setter mechanism due to collision or displacement.
[0035] The drive mechanism 40 is the component that enables the movement of the protective cover 30, and its output end is connected to the protective cover 30. Under the control of the drive mechanism 40, the protective cover 30 can move up and down and rotate, thereby opening or closing the opening 21. This independent drive method ensures that the protective action is performed solely by the protective cover 30, while the tool setting mechanism remains in a fixed position. It is not affected by collisions or displacements caused by the movement of the protective cover 30, nor by the vibration and inertia of the drive mechanism 40, thus ensuring the stability and measurement accuracy of the tool setting device 2 during the protective process.
[0036] The tool setter 2 adopts an integrated rotary and vertical linear motion drive mechanism 40, which eliminates the need for connecting rods and hinges. The upper protective cover and lower protective cover of the tool setter 2 have a simple structure, fewer parts, small space occupation, low manufacturing cost, convenient assembly and debugging, and simple movement, which improves the reliability of the motion protection of the tool setter 2.
[0037] This application achieves a fixed connection between the tool setter 2 and the base 10 and the machine tool, preventing it from participating in any movement. This completely avoids positioning offsets that may be caused by moving parts, fundamentally eliminating new motion positioning errors. The protective action is completed independently by the protective cover 30. The tool setting mechanism always remains in a fixed position and will not collide or shift due to the movement of the protective cover 30, nor will it be affected by the vibration and inertia of the drive mechanism 40. The clearance chamber design ensures that the protective cover 30 does not contact the tool setting mechanism when opening and closing, avoiding accuracy offsets caused by mechanical interference and fully preserving the original measurement accuracy of the tool setter 2. In addition, the protective chamber can effectively isolate the tool setter 2 from the corrosion of chips, coolant, etc., preventing aging of the seals and contamination of the tool setting surface. When the protective cover 30 is closed, the opening 21 is completely sealed, and the tool setting mechanism is only exposed during testing, greatly reducing the impact of harsh environments on the equipment and achieving effective protection for the tool setter 2.
[0038] Reference Figure 3 According to the protective device 1 of the machine tool tool setting instrument provided by the present invention, a connecting block 50 is also included. The connecting block 50 is connected between the drive mechanism 40 and the protective cover 30 and is located in the clearance chamber. The connecting block 50 and the clearance chamber are conformally arranged to each other.
[0039] Understandably, the connecting block 50, as an intermediate connecting part 52 between the drive mechanism 40 and the protective cover 30, can reliably transmit the power generated by the drive mechanism 40 to the protective cover 30. Since vibrations and other effects occur during machine tool operation, a stable connection ensures the stability and accuracy of power transmission, preventing abnormal movement of the protective cover 30 due to loose connections, such as the inability to properly open or close the opening 21, thus affecting the normal use and protective effect of the tool setter 2.
[0040] The connecting block 50 and the clearance chamber are conformally configured so that the connecting block 50 can better adapt to the shape of the clearance chamber, reducing unnecessary space occupation, while ensuring the stability of the protective cover 30 during movement.
[0041] Reference Figure 3 According to the protective device 1 for a machine tool tool setting device provided by this utility model, it further includes a tool setting device base plate 60. One end of the tool setting device base plate 60 is connected to the base 10, and the other end extends toward the opening 21. The tool setting device base plate 60 is used to install the tool setting device 2 on the base 10. One end of the tool setting device base plate 60 near the opening 21 and the other end of the connecting block 50 that cooperates with the tool setting device base plate 60 when closed are provided with a positioning groove 61 and a positioning block 51. The positioning groove 61 and the positioning block 51 cooperate with each other to position the closing direction of the protective cover 30.
[0042] Understandably, the tool setter base plate 60 is connected to the base 10 at one end and extends towards the opening 21 at the other end, providing a dedicated mounting platform for the tool setter 2. This allows the tool setter 2 to be mounted stably and reliably on the base 10, ensuring that its position will not easily shift during measurement and other operations, thereby ensuring the accuracy and reliability of the measurement results.
[0043] Positioning grooves 61 and positioning blocks 51 (or vice versa) are respectively provided at one end of the tool setter base plate 60 near the opening 21 and at the end of the connecting block 50 that mates with it when closed. When the protective cover 30 is closed, the positioning block 51 can accurately embed into the positioning groove 61. This mutual cooperation provides precise positioning for the closing direction of the protective cover 30. This ensures that the protective cover 30 can accurately reach the predetermined position each time it is closed, avoiding problems such as collisions and interference between the protective cover 30 and the tool setter 2 or other components due to deviations in the closing direction.
[0044] Reference Figure 2 According to the protective device 1 of the machine tool tool setting instrument provided by the present invention, the positioning groove 61 includes two opposite and outwardly inclined inner inclined surfaces 611, and the positioning block 51 is provided with two outer inclined surfaces 511 that match the inner inclined surfaces 611. The inner inclined surfaces 611 and the outer inclined surfaces 511 cooperate to guide the opening or closing of the protective shell 20.
[0045] Understandably, the two relatively inclined inner slopes 611 and outer slopes 511 form a wedge-shaped guide structure. When the protective cover 30 opens and closes, the slopes will generate a lateral corrective force. Even if there is a slight movement deviation in the drive mechanism 40, the slopes can guide the protective cover 30 to move along the correct trajectory, avoiding deviation or jamming when closing, and ensuring smooth and controllable opening and closing action.
[0046] Before the cover is fully closed, the beveled surfaces gradually come into contact, replacing point contact with surface contact to disperse the impact force and reduce vibration when the protective cover 30 is in place. At the same time, the symmetrical design of the double beveled surfaces can limit the circumferential deflection of the protective cover 30, ensuring the stability of the posture after closing and avoiding the sealing effect being affected by vibration or displacement.
[0047] Reference Figure 2 According to the present invention, a protective device 1 for a machine tool tool setting device is provided, wherein the end of the connecting block 50 away from the tool setting device base plate 60 is bent toward the base 10 to form a connecting part 52, and the connecting part 52 is connected to the protective cover 30 by fasteners.
[0048] Understandably, the connecting part 52 formed by bending provides a large area and a high degree of fit for the drive mechanism 40 and the protective cover 30. With the rigid fixation of fasteners (such as bolts and screws), it can prevent loosening and shaking during power transmission, and ensure that the up-and-down movement and rotation power of the drive mechanism 40 is accurately and stably transmitted to the protective cover 30, thus ensuring smooth opening and closing.
[0049] Reference Figure 1 According to the present invention, a protective device 1 for a machine tool tool setting device is provided. The protective housing 20 includes a first housing 22 and a second housing 23. The first housing 22 surrounds the outside of the base 10 and forms a side opening 21. The second housing 23 is detachably connected to the side opening 21.
[0050] It is understandable that the first housing 22 surrounds the outside of the base 10 to form a side opening 21. During assembly, the tool setter 2, drive mechanism 40 and other components can be installed on the base 10 first, and then the internal components can be aligned and connected through the side opening 21, avoiding the restriction of the operating space by the overall enclosed housing. The second housing 23 is detachable, which facilitates the adjustment of component positions and troubleshooting of installation problems during the assembly stage, and improves debugging efficiency.
[0051] Reference Figure 1 , Figure 4 and Figure 5 According to the protective device 1 of the machine tool tool setting device provided by the present invention, a connecting component is also included. The connecting component is connected between the base 10 and the machine tool. The connecting component includes a connecting plate 70 and a mounting plate 80. The connecting plate 70 and the mounting plate 80 are arranged at an angle to each other. One end of the connecting plate 70 is connected to the machine tool, and the other end is connected to the mounting plate 80. The mounting plate 80 is used to connect and fix to the base 10.
[0052] It is understandable that the connecting plate 70 and the mounting plate 80 are at an angle to each other (such as vertical or a specific tilt angle). The connection posture can be adjusted according to the spatial layout and angle requirements of the machine tool mounting surface, which solves the problem of spatial misalignment or angle deviation between the machine tool and the tool setter 2, and expands the range of applicable models of the protective device.
[0053] Secondly, the angled connection forms a rigid support structure, which transfers the weight of the base 10 (and the tool setter 2) and the vibration load during operation to the machine tool in layers through the mounting plate 80 and the connecting plate 70. This avoids loosening of the connection caused by single-point force, enhances the connection rigidity between the overall device and the machine tool, and indirectly ensures the fixed stability of the tool setter 2.
[0054] Reference Figure 1 , Figure 3 and Figure 5 According to the protective device 1 of the machine tool tool setting instrument provided by the present invention, it further includes a cleaning air nozzle 90, which is disposed in the protective chamber and located on the periphery of the tool setting instrument 2. The blowing direction of the cleaning air nozzle 90 is directed towards the tool setting mechanism of the tool setting instrument 2.
[0055] Understandably, the cleaning air nozzle 90 is located within the protective chamber and surrounds the tool setter on both sides, with the air blowing direction directly towards the tool setting mechanism (such as the tool setting face, detection contacts, and other core areas). This allows for the targeted removal of fine chips, coolant residue, and other impurities adhering to the tool setting mechanism. Compared to existing external air blowing methods, its cleaning range is more focused and its force is more concentrated, effectively solving the problem of fine chip adhesion after the cutting fluid evaporates.
[0056] This utility model also provides a tool setting device assembly, including a tool setting device 2 and a protective device 1 as described above for a machine tool tool setting device, wherein the tool setting device 2 is disposed in a protective chamber. Since the protective device 1 of the aforementioned machine tool tool setting device is used in the tool setting device assembly, the embodiments of this tool setting device assembly include all the technical solutions of all embodiments of the protective device 1 of the aforementioned machine tool tool setting device, and the achieved technical effects are completely the same, and will not be repeated here.
[0057] This utility model also provides a machine tool, including the protective device 1 of the machine tool tool setting device as described above, or the tool setting device assembly as described above. Since the protective device 1 or the tool setting device assembly of the machine tool is used in the machine tool, the embodiment of this machine tool includes all the technical solutions of all embodiments of the protective device 1 or the tool setting device assembly of the machine tool tool setting device, and the technical effects achieved are exactly the same, so they will not be described again here.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
