Description

Technical Field

[0001] This utility model belongs to the field of tool setting adjustment, and specifically relates to a contact-type tool setting mechanism. Background Technology

[0002] During the workpiece processing, auxiliary time such as workpiece loading and unloading and tool adjustment accounts for a considerable proportion of the processing cycle. Tool adjustment is time-consuming, labor-intensive, and difficult to be accurate. Finally, a trial cut is required. The use of a tool setter has shown great advantages. It can not only quickly confirm the correctness of tool use, but also monitor the damage of the tool.

[0003] Existing contact tool setters are typically rigidly mounted on machine tools. Once the mounting position is determined, it is difficult to adjust and cannot compensate for tool setting deviations caused by assembly errors, thermal deformation, or mechanical vibration. Furthermore, the traditional threaded adjustment process is cumbersome and prone to backlash, which seriously affects the accuracy and stability of the tool setter's position. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a contact-type tool setting mechanism that features a simple structure, good stability, and integrated high-precision bidirectional fine-tuning and automatic cleaning functions.

[0005] The objective of this utility model can be achieved by addressing the following technical problem: a contact-type tool setting mechanism is proposed for mounting on the side wall of a rotary table, comprising:

[0006] Mounting bracket;

[0007] A tool setter is detachably connected to the mounting bracket. The tool setter is equipped with a sensing head that extends outside the mounting bracket and is used to detect the length of the tool.

[0008] An adjusting block is connected to the bottom of the mounting bracket. The rotary table includes a fixed frame and a rotating frame movably connected thereto. The adjusting block is movably connected to the end side wall of the fixed frame.

[0009] The system includes a longitudinal adjustment component and a lateral adjustment component. The longitudinal adjustment component is connected between the mounting bracket and the adjusting block, and the lateral adjustment component is connected between the adjusting block and the fixing frame. Both the longitudinal and lateral adjustment components include elastic cylindrical pins. The elastic cylindrical pins can change the lateral distance between the adjusting block and the fixing frame, as well as the longitudinal distance between the mounting bracket and the adjusting block, due to their elastic deformation, so that the sensing head is in the required correction position.

[0010] A conveying assembly, mounted on a fixed frame and connected to the tool setter, is used to introduce gas into the tool setter and to clean the end of the sensing head.

[0011] In the aforementioned contact-type tool setting mechanism, both the longitudinal adjustment component and the transverse adjustment component further include several equally spaced locking elements. These locking elements can restrict the movement of the adjusting block and the mounting bracket after the elastic cylindrical pin is adjusted.

[0012] In the aforementioned contact-type tool setting mechanism, the adjusting block includes a horizontal part and a vertical part connected to each other. The horizontal part is used to support and connect the mounting bracket; the vertical part is used to be assembled on the end side wall of the fixed frame.

[0013] In the aforementioned contact-type tool setting mechanism, the mounting bracket includes a horizontal connecting part and a vertical connecting part that are connected to each other. The horizontal connecting part is placed on the horizontal part, and the tool setting device is fixed to the top of the vertical connecting part. The elastic cylindrical pin can adjust the height difference between the horizontal connecting part and the horizontal part, as well as the distance between the vertical part and the fixed frame.

[0014] In the aforementioned contact-type tool setting device mechanism, the tool setting device is also equipped with an air pipe, which is located below the sensing head.

[0015] In the aforementioned contact-type tool setting mechanism, both the vertical and horizontal connecting parts are provided with connecting holes, and both the fixing frame and the horizontal part are provided with locking holes. The locking member passes through the connecting hole and is connected in the locking hole.

[0016] In the aforementioned contact-type tool setting device mechanism, the air pipe is provided with an air outlet, which is used to discharge the gas in the air pipe to the end of the sensing head.

[0017] In the aforementioned contact-type tool setting device mechanism, the mounting bracket further includes a protective cover plate, which forms an interconnected cavity and a positioning hole. The tool setting device is placed inside the cavity, and the sensing head and the air tube pass through the positioning hole to extend outside the cavity.

[0018] In the aforementioned contact-type tool setting device mechanism, the tool setting device also has a first vent and a second vent. The first vent is connected to the air pipe, and the second vent is connected to the sensing head.

[0019] In the aforementioned contact-type tool setting device mechanism, the conveying assembly includes a loading frame, fixed pipe heads, and a pipe. The loading frame is used to place an air supply device. Several fixed pipe heads are connected to the outer wall of the loading frame. One end of the pipe is connected to the loading frame, and the other end is connected to the first vent and the second vent.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The contact tool setting mechanism of this utility model sets longitudinal and transverse adjustment components composed of elastic cylindrical pins between the mounting bracket and the fixed frame, so as to realize stepless, elastic fine adjustment and rapid locking of the position of the tool setting sensor head, effectively compensating for assembly errors and thermal deformation; at the same time, a gas delivery component is introduced to automatically clean the sensor head, which significantly improves the tool setting accuracy and system reliability.

[0022] (2) The horizontal and vertical parts form a stable L-shaped support structure, which can effectively support the mounting bracket through the horizontal part to ensure the overall load-bearing strength, and can also be firmly assembled to the end side wall of the rotary table fixing frame through the vertical part to enhance the connection rigidity, which helps to improve the structural stability and anti-interference ability of the entire tool setting mechanism.

[0023] (3) The air outlet on the air tube is beneficial for the gas in the air tube to clean the end of the sensor head after multiple tool setting, ensuring the accuracy of tool setting. Attached Figure Description

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0035] like Figures 1 to 3 As shown, this utility model discloses a contact-type tool setting device 3 mechanism, which is used to be mounted on the side wall of a rotary table. It includes: a mounting bracket 2; a tool setting device 3, detachably connected to the mounting bracket 2, the tool setting device 3 having a sensing head 30 extending beyond the mounting bracket 2 for detecting the length of the tool; an adjusting block 4 connected to the bottom of the mounting bracket 2; the rotary table including a fixed frame 10 and a rotating frame 11 movably connected thereto, the adjusting block 4 being movably connected to the end side wall of the fixed frame 10; a longitudinal adjusting assembly 50 and a transverse adjusting assembly 51; and a connection between the mounting bracket 2 and the adjusting block 4. The longitudinal adjustment component 50 and the transverse adjustment component 51 are connected between the adjustment block 4 and the fixed frame 10. Both the longitudinal adjustment component 50 and the transverse adjustment component 51 include elastic cylindrical pins 520. The elastic cylindrical pins 520 can change the transverse distance between the adjustment block 4 and the fixed frame 10 and the longitudinal distance between the mounting bracket 2 and the adjustment block 4 due to their elastic deformation, so that the sensing head 30 is in the required correction position. The conveying component 6 is provided on the fixed frame 10 and connected to the tool setter 3. The conveying component 6 is used to introduce gas into the tool setter 3 and clean the end of the sensing head 30.

[0036] like Figures 1 to 3As shown, this embodiment achieves stable assembly and precise positioning of the tool setter 3 on the side wall of the rotary table by setting up the mounting bracket 2, the tool setter 3, the adjusting block 4, the longitudinal and transverse adjustment components 51, and the conveying component 6. Specifically, the tool setter 3 is detachably connected (by screws or other screw structures) to the mounting bracket 2 for easy maintenance and replacement; the exposed sensor head 30 can directly contact the tool to achieve accurate detection of the tool length; the adjusting block 4 is connected to the end side wall of the fixed frame 10 of the rotary table, and in conjunction with the elastic cylindrical pin 520 in the longitudinal and transverse adjustment components 51, the elastic cylindrical pin 520 undergoes radial compression deformation due to its elastic structure, allowing the adjusting block 4 to undergo slight transverse displacement relative to the fixed frame 10 (i.e., Figure 1 The direction of the X-axis shown) and the vertical movement of the mounting bracket 2 relative to the adjusting block 4 (i.e. Figure 1 (As shown in the Z-axis direction) until the sensing head 30 on the tool setter 3 is adjusted to the ideal position and then locked again. The overall operation is convenient and quick, effectively ensuring the tool setting accuracy. At the same time, the conveying component 6 is set to introduce gas into the tool setter 3 and clean the end of the sensing head 30, effectively preventing chips, oil stains and other impurities from adhering and causing false detection or damage, thus improving the reliability of detection and the service life of the equipment.

[0037] Both the longitudinal adjustment assembly 50 and the lateral adjustment assembly 51 also include several equally spaced locking elements 521, which can restrict the movement of the adjustment block 4 and the mounting bracket 2 after the elastic cylindrical pin 520 is adjusted.

[0038] like Figure 3 As shown, although the elastic cylindrical pin 520 achieves gapless fine-tuning and initial self-locking through its own elastic deformation, in CNC machining environments with high vibration and high dynamic loads, relying solely on material elastic pre-tightening may still pose a risk of slow loosening or slight displacement after long-term use. Therefore, this invention further adds several equidistantly distributed locking elements 521 (using fastening screws or bolts, etc.) to the longitudinal adjustment component 50 and the transverse adjustment component 51 to mechanically and rigidly lock the adjustment structure after adjustment, thereby improving the overall stability and anti-interference capability of the structure. After the elastic cylindrical pin 520 completes position adjustment through elastic deformation, the locking element 521 can quickly lock the relative positions between the adjustment block 4 and the fixed frame 10, and between the mounting bracket 2 and the adjustment block 4, preventing positional displacement caused by vibration or external force. The elastic cylindrical pin 520 works synergistically to ensure the stability and repeatability of the tool setter 3 during long-term operation. Preferably, the equidistant distribution design facilitates multi-level fine adjustment, improving adjustment efficiency and operational convenience.

[0039] The adjusting block 4 includes a horizontal part 40 and a vertical part 41 that are connected to each other. The horizontal part 40 is used to support and connect the mounting bracket 2; the vertical part 41 is used to be assembled on the end side wall of the fixing frame 10.

[0040] like Figure 3 As shown, in this embodiment, the adjusting block 4 is designed as a horizontal part 40 and a vertical part 41 that are connected to each other to form a stable L-shaped support structure. The horizontal part 40 can effectively support the mounting bracket 2 and ensure the overall load-bearing strength. The vertical part 41 can be firmly assembled to the end side wall of the rotary table fixing frame 10 to enhance the connection rigidity. This integrated structure simplifies the assembly process, improves the space utilization, and provides a reliable mechanical basis for subsequent horizontal and vertical adjustments. It also helps to improve the structural stability and anti-interference ability of the entire tool setting device 3 mechanism.

[0041] Mounting bracket 2 includes a horizontal connecting part 20 and a vertical connecting part 21 that are connected to each other. The horizontal connecting part 20 is placed on the horizontal part 40. The tool setter 3 is fixed to the top of the vertical connecting part 21. The elastic cylindrical pin 520 can adjust the height difference between the horizontal connecting part 20 and the horizontal part 40, as well as the distance between the vertical part 41 and the fixing frame 10.

[0042] like Figure 3 As shown, the mounting bracket 2 in this embodiment adopts a structure composed of a horizontal connecting part 20 and a vertical connecting part 21, so as to adapt to the L-shaped structure of the adjusting block 4, so that the horizontal connecting part 20 is stably placed on the horizontal part 40 of the adjusting block 4 to achieve stable support; the vertical connecting part 21 is used to fix the tool setter 3 at its top, so as to reasonably distribute the force. More importantly, the elastic cylindrical pin 520 can adjust the height difference (longitudinal distance) between the horizontal connecting part 20 and the horizontal part 40, and the distance (lateral distance) between the vertical part 41 and the fixing frame 10, thereby realizing the precise fine adjustment of the sensing head 30 in two directions, meeting the high-precision calibration requirements of the spatial position of the sensing head 30 under different working conditions, and significantly improving the adaptability and accuracy of tool setting.

[0043] Both the vertical part 41 and the horizontal connecting part 20 are provided with connecting holes 200, and both the fixing bracket 10 and the horizontal part 40 are provided with locking holes 400. The locking member 521 passes through the connecting hole 200 and is connected in the locking hole 400.

[0044] In this embodiment, an air pipe 31 is added to the tool setting device 3 and positioned below the sensor head 30, forming a reasonable air path layout. This design allows the gas to flow upwards from bottom to top, directly acting on the end area of ​​the sensor head 30. This facilitates the blowing away of fine chips or coolant residues accumulated at the bottom of the sensor head 30, preventing contaminant deposition from affecting the sensing sensitivity. Simultaneously, the air pipe 31 is positioned close to the sensor head 30 but does not obstruct the detection path, thus not affecting the tool setting operation, balancing cleaning functionality and detection reliability.

[0045] The tool setting device 3 is also equipped with an air pipe 31, which is located below the sensing head 30. The air pipe 31 is provided with an air outlet 310, which is used to discharge the gas in the air pipe 31 to the end of the sensing head 30.

[0046] In this embodiment, the air outlet 310 faces the end of the sensing head 30, so that the compressed gas provided by the conveying assembly 6 can be directionally ejected through the air outlet 310 to form a local airflow field, which effectively removes dust, oil mist or metal particles attached to the surface of the sensing head 30. This design realizes an automatic online cleaning function, eliminating the need for manual cleaning during machine shutdown, greatly reducing the maintenance frequency, improving the automation level and continuous operation capability of the equipment, and also extending the service life of the sensing head 30, ensuring the accurate transmission of the tool setting signal.

[0047] The mounting bracket 2 also includes a protective cover plate 22, which forms an interconnected cavity and a positioning hole 220. The knife setting device 3 is placed inside the cavity, and the sensing head 30 and the air tube 31 pass through the positioning hole 220 to extend outside the cavity.

[0048] like Figure 1 As shown, this embodiment adds a protective cover plate 22 to the mounting bracket 2 to form a closed cavity to accommodate the main body of the tool setter 3. This effectively isolates dust, coolant splashes, and mechanical collisions from the external cutting environment, protecting the internal precision components. At the same time, the positioning hole 220 on the protective cover plate 22 allows the sensing head 30 and the air tube 31 to pass through, which not only realizes the function but also maintains the seal, significantly improving the reliability and durability of the tool setter 3 in harsh processing environments, reducing the failure rate, and meeting the requirements for long-term stable operation in industrial sites.

[0049] The tool setting device 3 also has a first vent 32 and a second vent 33. The first vent 32 is connected to the air pipe 31, and the second vent 33 is connected to the sensing head 30.

[0050] like Figure 2 As shown, in this embodiment, a first vent 32 and a second vent 33 are provided on the body of the tool setter 3. The first vent 32 is connected to an air pipe 31, so that gas can pass through the air pipe 31 and be sprayed onto the end of the sensing head 30 through the air outlet 310. It is worth noting that the air outlet 310 is coplanar with the surface of the sensing head 30 to achieve a more accurate and stable cleaning effect. The second vent 33 is connected to the sensing head 30, so that some gas can flow directly from the inner wall of the tool setter 3 toward the sensing head 30. In other words, the second vent 33 helps to prevent external impurities or processing debris from entering the tool setter 3 from the sensing head 30, improving the stability of the tool setter 3 during tool setting operations, and also extending its service life.

[0051] The conveying assembly 6 includes a loading frame 60, fixed pipe heads 61, and pipes. The loading frame 60 is used to place the air supply equipment. Several fixed pipe heads 61 are connected to the outer wall of the loading frame 60. One end of the pipe is connected to the loading frame 60, and the other end is connected to the first vent 32 and the second vent 33.

[0052] like Figure 1 As shown, the conveying component 6 in this embodiment includes a loading frame 60, fixed pipe heads 61, and pipes. The loading frame 60 is used to centrally house air supply equipment (such as air pumps or air source interfaces) to achieve centralized management and modular integration. Multiple fixed pipe heads 61 are located on the outer wall of the loading frame 60 and can be used to connect pipes of different branches to meet the needs of multi-point air supply. One end of the pipe is connected to the loading frame 60, and the other end can extend into the cavity and be connected to the first vent hole 32 and the second vent hole 33 of the tool setter 3 respectively to ensure stable gas delivery. This structure realizes the orderly integration and efficient distribution of the air source system, improves the reliability of air supply and the convenience of maintenance, and is especially suitable for complex machine tool systems with multiple workstations or multiple sensors sharing the same air source.

[0053] It should be noted that the tool setting device 3 structure in this embodiment is applied to a rotary worktable. The structure and working principle between the fixed frame 10 and the rotating frame 11 on the rotary worktable are existing technologies and will not be described in detail here.
