Description

Technical Field

[0001] This utility model relates to the field of machining, specifically to a feed measuring device for machining internal grooves. Background Technology

[0002] In the field of machining, especially when grooving the inner hole of a workpiece, the operator cannot directly observe the actual feed rate of the tool because the tool extends into the hole to perform cutting operations. This may lead to a decrease in machining accuracy and inconsistency in machining quality.

[0003] In traditional internal grooving processes, because the cutting tool is located inside the workpiece, operators cannot directly observe its specific position and feed rate. The lack of effective real-time monitoring means that feed rate adjustments during machining rely on experience, which is prone to errors. Any deviation can lead to dimensional inconsistencies and increased scrap rates. Utility Model Content

[0004] The main objective of this invention is to provide a feed measuring device for machining internal grooves in holes, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: including a boring tube, and a feed drive device is provided inside the boring tube. The feed drive device drives the cutting tool to move and feed through a transmission rod.

[0006] A grating component is provided on one side of the boring tube. The feed drive device is connected to the reading head in the grating component. While the feed drive device drives the tool to move and feed, it drives the reading head to slide on the grating ruler, thereby calculating and feeding back the feed amount.

[0007] The feed drive device includes a lead screw, a transmission rod joint and a connecting rod connected in sequence. An end cap and a threaded sleeve are fixed at the end of the boring tube. The lead screw and the threaded sleeve are threadedly connected. The bottom of the reading head is fixedly connected to the connecting rod through an indicator rod clamp bracket.

[0008] A rotating shaft is provided between the lead screw and the transmission rod joint. One end of the rotating shaft abuts against the transmission rod joint and rotates, while the other end is fixedly connected to the lead screw.

[0009] Preferably, the rotating shaft has a boss in the middle, and multiple bearings on both sides of the boss abut against the transmission rod joint. The transmission rod joint has a threaded locking ring at the end, which is used to fix the bearing in the transmission rod joint.

[0010] Preferably, the locking threaded ring has an opening in the middle of one side, and the two ends of the opening are connected by bolts. The locking threaded ring and the transmission rod joint are locked by tightening the bolts.

[0011] Preferably, the end of the lead screw abuts against the inside of the rotating shaft via a connecting key, and a corresponding connecting hole is provided on one side of the lead screw and the rotating shaft, with a set screw fixed inside the connecting hole.

[0012] Preferably, the grating ruler is fixed with grating component clamp brackets at both ends. The grating component clamp brackets include an upper clamp and a lower clamp. The upper clamp and the lower clamp are spliced ​​and fitted on the outside of the boring tube, and their two ends are connected and fixed by bolts.

[0013] A mounting base is fixed on the upper clamp, and the end of the grating ruler is fixed to the mounting base by bolts.

[0014] Preferably, the boring tube has through grooves on both sides, and a positioning block is fixed in the middle of the upper clamp, with the positioning block abutting against the through groove.

[0015] This utility model provides a feed measuring device for machining internal grooves in holes, with the following advantages:

[0016] 1. A precision feed drive and measurement system, consisting of a lead screw, a linear encoder, and a reading head, enables micron-level control of the tool feed rate, ensuring high precision during machining. The reading head monitors and provides real-time feedback on the tool's position, allowing the control system to adjust the feed rate and position promptly, further improving machining accuracy.

[0017] 2. The grating component clamp bracket fits tightly with the through slot on the boring tube via positioning blocks, ensuring the accuracy and stability of the grating ruler installation and thus guaranteeing consistency in each processing step. A real-time data feedback mechanism allows the control system to automatically correct any deviations, ensuring consistent product dimensions throughout continuous processing.

[0018] 3. The design of the upper and lower clamps makes the installation of the grating components simpler and faster, while also facilitating daily maintenance and troubleshooting. Components such as the rotating shaft and locking threaded rings have adopted optimized designs, enhancing the maintainability and reliability of the system.

[0019] 4. This device is not only suitable for standard internal hole grooving operations, but can also adapt to workpieces of different sizes and shapes, exhibiting high flexibility and versatility. Its modular design allows the system to be expanded or upgraded as needed to meet diverse processing requirements. Attached Figure Description

[0027] like Figures 1-5 As shown, a feed measuring device for machining grooves in a hole includes a boring tube 1, and a feed drive device is provided inside the boring tube 1. The feed drive device drives the cutting tool to move and feed through a transmission rod 11.

[0028] A grating component is provided on one side of the boring tube 1. The feed drive device is connected to the reading head 7 in the grating component. While the feed drive device drives the tool to move and feed, it drives the reading head 7 to slide on the grating ruler 6, thereby calculating and feeding back the feed amount.

[0029] The feed drive device includes a lead screw 4, a transmission rod joint 9 and a connecting rod 10 connected in sequence. The end cap 2 and the threaded sleeve 3 are fixed at the end of the boring tube 1. The lead screw 4 is threadedly connected to the threaded sleeve 3. The bottom of the reading head 7 is fixedly connected to the connecting rod 10 through the indicator rod clamp bracket 12.

[0030] A rotating shaft 8 is provided between the lead screw 4 and the transmission rod joint 9. One end of the rotating shaft 8 abuts against the transmission rod joint 9 and rotates, while the other end is fixedly connected to the lead screw 4.

[0031] While the feed drive device drives the tool to move and feed via the transmission rod 11, it can also move the reading head 7 in the grating component to measure on the grating ruler 6, thereby accurately feeding back the amount of movement. The feed drive device rotates the lead screw 4, thereby pushing the transmission rod joint 9, the connecting rod 10, and the transmission rod 11 to move. The connecting rod 10 is connected to the reading head 7 via the indicator rod clamp bracket 12, thereby moving it together and providing real-time and accurate feedback of the movement feed data. The rotating shaft 8 can convert the linear rotation of the lead screw 4 into the linear movement of the transmission rod joint 9.

[0032] The feed drive unit consists of a lead screw 4, a transmission rod joint 9, and a connecting rod 10. The lead screw 4 is threadedly connected to the lead sleeve 3 fixed at the end of the boring tube 1. When the lead screw rotates, it moves along its axial direction, thereby pushing the entire feed drive assembly forward or backward.

[0033] A rotating shaft 8 is provided between the lead screw 4 and the transmission rod joint 9. Its function is to convert the rotational motion of the lead screw into the linear motion of the transmission rod joint. The advantage of this design is that it can reduce the torque directly acting on the lead screw while maintaining high positioning accuracy.

[0034] The grating measurement system includes a grating ruler 6 and a reading head 7. As the feed drive moves, the reading head 7 slides on the grating ruler and can read position information very accurately. The reading head 7 is fixed to the connecting rod 10 by an indicator rod clamp bracket 12, ensuring that the reading head moves synchronously with the feed mechanism.

[0035] The aforementioned grating measurement system allows for real-time acquisition of precise tool position data relative to the workpiece. This information is crucial for CNC machine tools because it enables the control system to adjust parameters based on actual machining conditions to achieve optimal machining results.

[0036] Preferably, the rotating shaft 8 has a boss in the middle, and the two sides of the boss abut against the transmission rod joint 9 through multiple bearings. The transmission rod joint 9 has a threaded locking ring 13 at the end, which is used to fix the bearing in the transmission rod joint 9.

[0037] The locking threaded ring 13 has an opening in the middle of one side, and the two ends of the opening are connected by bolts 14. The locking threaded ring 13 is locked to the transmission rod joint 9 by tightening the bolts 14.

[0038] The end of the lead screw 4 abuts against the rotating shaft 8 via a connecting key. The lead screw 4 and the rotating shaft 8 are provided with corresponding connecting holes on one side, and a set screw 15 is fixed in the connecting hole.

[0039] The boss located in the middle of the rotating shaft 8 provides a support point for the bearing, allowing the rotating shaft to rotate smoothly within the transmission rod joint 9 without deviation. This design helps reduce friction and improve motion accuracy. Multiple bearings on both sides of the boss abut against the inside of the transmission rod joint 9, ensuring good alignment of the rotating shaft 8 during rotation while allowing it to rotate freely without excessive resistance. This contributes to improving the efficiency and lifespan of the entire system.

[0040] The locking threaded ring 13 is located inside the end of the transmission rod joint 9, and secures the bearing inside via a threaded connection. The function of the locking threaded ring is to prevent the bearing from loosening or shifting, ensuring that the relative position between the rotating shaft 8 and the transmission rod joint 9 remains constant, thereby guaranteeing the stability of the mechanism during operation. The locking threaded ring has an opening on one side, and the two ends of this opening can be connected to each other via bolts 14. When the bolts are tightened, a secure lock-on state is formed between the locking threaded ring 13 and the transmission rod joint 9, further enhancing the safety and reliability of the structure.

[0041] One end of the lead screw 4 is connected to the rotating shaft 8 via a connecting key, which can effectively transmit torque. In addition, a connecting hole is provided at the corresponding position of the lead screw 4 and the rotating shaft 8, and a set screw 15 is installed in the hole to further strengthen the connection between the two and avoid loosening due to long-term use.

[0042] Preferably, the grating ruler 6 is fixed at both ends with a grating component clamp bracket 5. The grating component clamp bracket 5 includes an upper clamp 501 and a lower clamp 502. The upper clamp 501 and the lower clamp 502 are spliced ​​and fitted on the outside of the boring tube 1, and their two ends are connected and fixed by bolts.

[0043] A mounting base 503 is fixed on the upper clamp 501, and the end of the grating ruler 6 is fixed to the mounting base 503 by bolts.

[0044] The grating component clamp bracket 5 consists of an upper clamp 501 and a lower clamp 502. These two parts are spliced ​​together to form a complete ring structure that can be fitted onto the outside of the boring tube 1. This design allows the grating ruler to be securely mounted on the boring tube while facilitating disassembly and maintenance.

[0045] The upper clamp 501 and the lower clamp 502 are fixed together by bolts, ensuring that the entire clamp bracket is firmly wrapped around the boring tube 1. This split design not only simplifies the installation process, but also allows for easy adjustment or replacement of components when needed.

[0046] Mounting base 503 is mounted on upper clamp 501, and its main function is to provide a fixed mounting point for grating ruler 6. One end of the grating ruler is fixed to this mounting base by bolts, thereby ensuring that the position of the grating ruler remains stable, which is crucial for accurate measurement of feed rate.

[0047] Preferably, the boring tube 1 has through grooves 101 on both sides, and a positioning block 504 is fixed in the middle of the upper clamp 501, with the positioning block 504 abutting against the through groove 101.

[0048] The positioning block is a protruding part fixed to the upper clamp 501, designed to fit snugly into the through slots 101 on both sides of the boring tube 1. This design has several advantages:

[0049] Improved stability: By embedding the positioning block 504 into the through slot 101, the clamp bracket can be prevented from rotating and moving along the boring tube, thus increasing the stability of the overall structure.

[0050] Enhanced alignment accuracy: The cooperation between the positioning block 504 and the through slot 101 helps to ensure the accurate position of the grating ruler 6 relative to the boring tube 1, which is very important for maintaining the accuracy of the measurement system.

[0051] Simplified installation process: With clear positioning points, installers can more easily and accurately complete the installation of grating components.

[0052] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
