Description

Technical Field

[0001] This application relates to the field of equipment manufacturing technology, and more particularly to a combination adjustment device for the center height and end face of the guide wheel of a centerless grinder and a centerless grinder. Background Technology

[0002] In a centerless grinder, the grinding wheel and guide wheel spindle system are key functional components. Since these two functional components are independently installed on the bed, the grinding function of the centerless grinder requires the guide wheel frame to be rotated and adjusted in the vertical plane of the fixed body. At the same time, after the machine tool is assembled, it is necessary to adjust the center of the grinding wheel and guide wheel spindle to be at the same height as the mounting reference surface of the bracket, and adjust the front end face of the guide wheel to be lower than the end face of the grinding wheel.

[0003] In existing processing technologies, setting a rotary centering shaft on the fixed body can only satisfy the rotation function of the guide wheel frame and achieve equal height adjustment from the spindle center to the bracket mounting reference surface. It cannot adjust the parallel tolerance between the guide wheel end face and the grinding wheel end face. Generally, after final assembly and measurement, the adjusting shims of the guide wheel spindle system are machined in reverse order, and the thickness of the guide wheel chuck is turned to ensure that the equal height dimensions and end face flatness meet the standard requirements. Therefore, this structure, in actual production, not only has low production efficiency but also large adjustment accuracy errors, failing to meet current processing needs. Summary of the Invention

This greatly simplifies the adjustment process, reduces manual intervention and debugging time, and thus improves production efficiency. Attached Figure Description

[0025] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In existing processing technologies, setting a rotary centering shaft on a fixed body only satisfies the rotation function of the guide wheel frame. It cannot adjust the height of the guide wheel spindle center to the bracket mounting reference surface, nor the parallelism tolerance between the guide wheel end face and the grinding wheel end face. Generally, after final assembly and measurement, adjusting shims for the grinding wheel spindle system are added in reverse sequence, and the thickness of the guide wheel chuck is machined to ensure that the height and end face alignment meet standard requirements. Therefore, this structure, in actual production, not only results in low production efficiency but also large adjustment accuracy errors, failing to meet current processing needs.

[0027] Based on this, this application provides a combined adjustment device for the center height and end face of the guide wheel of a centerless grinder and a centerless grinder. The guide wheel frame of the centerless grinder achieves grinding angle rotation through an eccentric rotary shaft. The eccentric rotary shaft is installed with a centering slider, and the axial displacement adjustment of the guide wheel spindle system is achieved through a slider displacement adjustment device. Compared with traditional adjustment methods, this combined adjustment device achieves rapid and precise adjustment of the center height and end face parallelism difference of the guide wheel and grinding wheel through a mechanical structure, which can greatly simplify the adjustment process, reduce manual intervention and debugging time, and thus improve production efficiency.

[0028] Please see Figures 1 to 9The first aspect of this application provides a combined adjustment device for the center height and end face of the guide wheel of a centerless grinder. The device includes: an eccentric rotary shaft 4, an eccentric shaft set screw 5, a centering slider 8, a slider displacement adjustment screw 6, and an adjustment screw fixing bracket 7. The eccentric rotary shaft 4 is installed between the guide wheel frame mounting body 3 and the guide wheel spindle system 2 of the centerless grinder. A grinding wheel spindle system 1 is provided on one side of the guide wheel spindle system 2. The eccentric shaft set screw 5 is provided on the guide wheel spindle system 2, and the eccentric shaft set screw 5 is used to fasten the guide wheel frame and the eccentric rotary shaft 4 together. The centering slider 8 and the slider displacement adjustment screw 6 are both... The eccentric rotary shaft 4 and the centering slider 8 are installed in the guide wheel frame mounting body 3 and connected to the guide wheel spindle system 2. One end of the slider displacement adjusting screw 6 is connected to the centering slider 8, and the other end of the slider displacement adjusting screw 6 extends out of the guide wheel frame mounting body 3 and is connected to the adjusting screw fixing frame 7. The eccentric rotary shaft 4 is used to adjust the center height of the guide wheel on the guide wheel spindle system 2 and the center height of the grinding wheel on the grinding wheel spindle system 1. The centering slider 8, in conjunction with the slider displacement adjusting screw 6 and the adjusting screw fixing frame 7, is used to adjust the parallelism difference between the center end face of the grinding wheel and the center end face of the guide wheel.

[0029] First, the function and purpose of each component in this application will be explained: Eccentric rotary shaft 4: Eccentric rotary shaft 4 is a shaft part with an eccentric design. Its axis does not coincide with the axis of the outer cylindrical surface, and there is a certain eccentricity. Eccentric rotary shaft 4 is installed between the guide wheel frame mounting body 3 and the guide wheel spindle system 2 of the centerless grinder. By rotating eccentric rotary shaft 4, the height position of the guide wheel spindle system 2 relative to the grinding wheel spindle system 1 can be changed, thereby realizing the equal height adjustment of the guide wheel center and the grinding wheel center. This adjustment method is precise and adjustable, and can meet the height matching requirements under different grinding needs.

[0030] Eccentric shaft set screw 5: Eccentric shaft set screw 5 has a fastening function, with threads and a head, and is used to fix or lock other components. Eccentric shaft set screw 5 is set on the guide wheel spindle system 2 and is used to fasten the eccentric rotary shaft 4. After the position of the eccentric rotary shaft 4 is adjusted, tightening the eccentric shaft set screw 5 can prevent the eccentric rotary shaft 4 from shifting due to vibration or external force, and ensure the stability of the center height of the guide wheel and the grinding wheel.

[0031] Centering slider 8: Centering slider 8 has a sliding function. Centering slider 8 is installed in the guide wheel frame mounting fixture 3 and connected to the guide wheel spindle system 2. When the slider displacement adjustment screw 6 is adjusted, the centering slider 8 will move accordingly, thereby driving the guide wheel spindle system 2 to make a small position adjustment. This adjustment method helps to achieve the parallel difference adjustment between the center end face of the grinding wheel and the center end face of the guide wheel.

[0032] Slider displacement adjusting screw 6: The slider displacement adjusting screw 6 is a threaded rod-shaped part. One end is connected to the centering slider 8, and the other end extends out of the guide wheel bracket mounting body 3 and is connected to the adjusting screw fixing bracket 7. By rotating the slider displacement adjusting screw 6, its relative position with the centering slider 8 can be changed, thereby realizing the displacement adjustment of the centering slider 8. This adjustment method is precise and controllable, and can meet the end face parallelism difference adjustment requirements under different grinding needs.

[0033] Adjusting screw holder 7: The adjusting screw holder 7 is a component used to fix and support the slider displacement adjusting screw 6. It has a threaded hole that mates with the slider displacement adjusting screw 6. The adjusting screw holder 7 is mounted on the guide wheel frame mounting body 3 and serves as the carrier for controlling the slider displacement adjusting screw 6. By adjusting the screw holder 7, the stability and accuracy of the slider displacement adjusting screw 6 during the adjustment process can be ensured, thereby improving the reliability and precision of the entire adjustment device.

[0034] Therefore, the combined adjustment device for the center height and end face of the centerless grinding wheel of this application, through the coordinated work of its various components, achieves rapid and precise adjustment of the center height and end face parallelism difference of the guide wheel and grinding wheel through mechanical structure, compared with the traditional adjustment method. This greatly simplifies the adjustment process, reduces manual intervention and debugging time, and thus improves production efficiency.

[0035] The center height and end face adjustment device for the centerless grinding wheel guide roller of this machine adjusts the center height of the guide roller to be equal to that of the grinding wheel through the coordinated operation of each component: Specifically, the center height H1 of the mounting reference surface of the grinding wheel spindle system 1 to the bracket 9, the center height H2 of the mounting reference surface of the guide wheel spindle system 2 to the bracket 9, and the parallelism dimension of the end faces of the grinding wheel and the guide wheel are the three sets of dimensions that are the basic requirements for ensuring the basic dimensional accuracy of the centerless grinder. When it is necessary to adjust the guide wheel to be at the same height as the grinding wheel center, the operator uses a wrench to rotate the eccentric rotary shaft 4. Due to the eccentricity of the eccentric rotary shaft 4, as it rotates, the guide wheel spindle system 2 will produce a small vertical displacement around a virtual rotation center. By precisely controlling the rotation angle of the eccentric rotary shaft 4, the operator can gradually adjust the position of the guide wheel spindle system 2, so that the height difference between the center of the guide wheel and the center of the grinding wheel gradually decreases until they reach the same height.

[0036] Specifically, first, place the eccentric rotary shaft 4 in a horizontal position. Using a special inspection tool for centerless grinders, measure the height H1 between the grinding wheel spindle and the mounting reference surface, and the height H2 between the guide wheel spindle and the mounting reference surface. If H1 > H2, adjust the eccentric rotary shaft 4 clockwise with a hex wrench. By rotating the eccentricity of the eccentric rotary shaft 4, adjust the center of the guide wheel to be level with the center of the grinding wheel to meet the dimensional accuracy requirements. If H1 < H2, adjust counterclockwise. After the height adjustment is completed, lock the guide wheel frame to the eccentric rotary shaft 4 using the eccentric shaft set screw 5. This satisfies the center height adjustment of the grinding wheel spindle system 1 and the guide wheel spindle system 2, ensuring that the guide wheel frame is adjusted based on this center height during the grinding process of the centerless grinder.

[0037] Principle of adjusting the parallelism difference between the center end faces of the grinding wheel and the guide wheel: The centering slider 8 is installed in the guide wheel frame mounting body 3 and connected to the guide wheel spindle system 2. One end of the slider displacement adjusting screw 6 is connected to the centering slider 8, and the other end extends out of the guide wheel frame mounting body 3 and is connected to the adjusting screw fixing frame 7.

[0038] When the operator rotates the slider displacement adjusting screw 6, due to the fixed fit between the screw and the adjusting screw fixing bracket 7, rotating the adjusting screw fixing bracket 7 can drive the slider displacement adjusting screw 6 to rotate. At the same time, the rotation of the slider displacement adjusting screw 6 will drive the centering slider 8 connected to it to move linearly within the guide wheel frame mounting fixture 3. The linear movement of the centering slider 8 will drive the guide wheel spindle system 2 to move laterally, thereby achieving parallelism between the grinding wheel and the center end face of the guide wheel.

[0039] Specifically, move the feed saddle 12 of the centerless grinder, measure the parallel tolerance H3 between the end face of the grinding wheel and the end face of the guide wheel using a depth gauge, and adjust the centering slider 8 laterally by adjusting the slider displacement screw 6. Figure 5 This allows for the adjustment of the end faces of the grinding wheel spindle system 1 and the guide wheel spindle system 2.

[0040] Optionally, the guide wheel frame mounting body 3 is provided with a first opening 10, and the guide wheel spindle system 2 is provided with a second opening 11 corresponding to the first opening 10. The eccentric rotary shaft 4 is installed in the first opening 10 and the second opening 11.

[0041] In this embodiment of the application, a first opening 10 and a second opening 11 are respectively provided on the guide wheel frame mounting body 3 and the guide wheel spindle system 2, and the eccentric rotary shaft 4 is installed in these two openings. The first opening 10 and the second opening 11 are provided to realize the installation of the eccentric rotary shaft 4 and the position adjustment of the guide wheel spindle system 2 relative to the guide wheel frame mounting body 3, thereby achieving the adjustment target of the guide wheel and the grinding wheel center being at the same height.

[0042] The first opening 10 is formed on the guide wheel frame mounting body 3. Its shape and size are adapted to the eccentric rotary shaft 4. The first opening 10 is a circular hole with a diameter greater than the maximum outer diameter of the eccentric rotary shaft 4 to ensure that the eccentric rotary shaft 4 can be installed smoothly and has a certain amount of room for movement. However, the room for movement is controlled within a reasonable range to prevent the eccentric rotary shaft 4 from shaking excessively during operation.

[0043] The second opening 11, corresponding to the first opening 10, is located on the guide wheel spindle system 2. It is also a circular hole, and its dimensions match those of the eccentric rotary shaft 4 to ensure a stable connection and normal transmission between the eccentric rotary shaft 4 and the guide wheel spindle system 2. The second opening 11 is precisely aligned with the first opening 10, allowing the eccentric rotary shaft 4 to pass through both openings simultaneously, thus enabling connection and relative position adjustment between the guide wheel frame mounting fixture 3 and the guide wheel spindle system 2.

[0044] In practical work, when it is necessary to adjust the guide wheel and the grinding wheel center to be at the same height, the operator rotates the eccentric rotary shaft 4. Due to the eccentric design of the eccentric rotary shaft 4, its axis does not coincide with the axis of the outer circular surface, and there is a fixed eccentricity. During the rotation, the contact point between the eccentric rotary shaft 4 and the first opening 10 and the second opening 11 will change, which will cause the guide wheel spindle system 2 to produce a small vertical displacement relative to the guide wheel frame mounting body 3. By precisely controlling the rotation angle of the eccentric rotary shaft 4, the height difference between the center of the guide wheel and the center of the grinding wheel can be finely adjusted, and finally the two can be made to reach the same height.

[0045] By directly installing the eccentric rotary shaft 4 in the first opening 10 and the second opening 11, rotational motion and displacement changes can be accurately transmitted, making the adjustment of the guide wheel and the center of the grinding wheel more precise. At the same time, this installation method also facilitates precise control and measurement by the operator.

[0046] Optionally, the guide wheel spindle system 2 is provided with a screw mounting port, which is inclinedly disposed on the second opening 11 and extends through the second opening 11, and the eccentric shaft set screw 5 is installed in the screw mounting port.

[0047] In this embodiment of the application, in the center height and end face combination adjustment device of the guide wheel of the centerless grinder, a screw mounting port is provided on the guide wheel spindle system 2, and it is tilted to pass through the second opening 11 to install the eccentric shaft set screw 5. The purpose is to ensure that the eccentric rotary shaft 4 will not rotate unexpectedly due to vibration, external force or other factors during the operation of the centerless grinder, thereby maintaining the stable state of the guide wheel and the center of the grinding wheel being at the same height.

[0048] Specifically, the screw mounting port is angled on the second opening 11, meaning its axis is not parallel to the axis of the second opening 11, but rather at a certain angle. This angled arrangement is to ensure that the eccentric shaft set screw 5 applies pressure to the eccentric rotating shaft 4 from a specific direction when tightened, thus enhancing the fixing effect. The eccentric shaft set screw 5 is installed in the screw mounting port, and when tightened, it will make close contact with the eccentric rotating shaft 4, thereby fixing the eccentric rotating shaft 4 to the guide wheel spindle system 2.

[0049] In this embodiment, after the center height of the guide wheel and the grinding wheel is adjusted to a suitable position, the operator uses a tool to tighten the eccentric shaft set screw 5. Due to the inclined setting of the screw mounting port, as the eccentric shaft set screw 5 is tightened, its end will apply pressure to the eccentric rotary shaft 4 from the inclined direction. This inclined pressure will generate a component force acting in the rotation direction of the eccentric rotary shaft 4. This component force can effectively prevent the eccentric rotary shaft 4 from rotating during the operation of the centerless grinder. At the same time, the threaded engagement between the eccentric shaft set screw 5 and the inner wall of the screw mounting port will also generate additional friction, further enhancing the fixing effect.

[0050] During the operation of the centerless grinder, due to the reliable fixation of the eccentric shaft set screw 5, the eccentric rotary shaft 4 can always remain in the adjusted position and will not be displaced or rotated due to factors such as vibration and workpiece grinding force. This ensures the stability of the center height between the guide wheel and the grinding wheel.

[0051] Optionally, a feed saddle 12 is provided on the guide wheel frame mounting body 3, the guide wheel spindle system 2 is provided on the feed saddle 12, and the feed saddle 12 is mounted on the bracket 9.

[0052] In this embodiment, the feed saddle 12 serves as a component connecting the guide wheel spindle system 2 and the bracket 9. Its main function is to provide stable support for the guide wheel spindle system 2 and realize the feed motion of the guide wheel spindle system 2 in a specific direction. This feed motion can precisely adjust the relative position between the guide wheel and the grinding wheel, thereby controlling the grinding dimensions and shape accuracy of the workpiece.

[0053] The bracket 9 provides basic support for the entire guide wheel support and motion system, ensuring the stable installation of the entire system on the centerless grinder. The bracket 9 bears the various forces generated during the grinding process, including the guide wheel spindle system 2, the feed saddle 12, and the grinding process, ensuring the rigidity and stability of the system and reducing the impact of vibration and other factors on grinding accuracy.

[0054] Among them, the guide wheel frame mounting fixture 3 is a structure used to fix and support the guide wheel related components in the centerless grinder, while the feed saddle 12 is mounted on the guide wheel frame mounting fixture 3 and cooperates with the bracket 9. It is located between the guide wheel frame mounting fixture 3 and the bracket 9. The feed saddle 12 is fixed together with the guide wheel frame mounting fixture 3, but can also achieve relative movement on the bracket 9.

[0055] The guide wheel spindle system 2 is mounted on the feed saddle 12 and is tightly connected to the feed saddle 12 by bolts or other fixing methods. The position and angle of the guide wheel spindle system 2 can be adjusted according to the grinding requirements to ensure the correct relative position between the guide wheel and the grinding wheel.

[0056] The bracket 9 provides a basic support platform for the entire device, with a large bottom area and high strength. Its surface is compatible with the feed saddle 12. The bracket 9 is equipped with guide rails or grooves that match the guide structure of the feed saddle 12. The bracket 9 is installed on the bed of the centerless grinder and is located below the feed saddle 12, providing stable support for the feed saddle 12 and the guide wheel spindle system 2.

[0057] By precisely moving the feed saddle 12 on the bracket 9, the position of the guide wheel can be finely adjusted to achieve the end face adjustment of the grinding wheel spindle system 1 and the guide wheel spindle system 2.

[0058] Optionally, a preset distance is provided between the center of the guide wheel and the center of the grinding wheel.

[0059] In this embodiment, the preset spacing can be adjusted by adjusting the position of the guide wheel bracket mounting body 3 on the centerless grinder bed, or by adjusting the movement of the feed saddle 12 on the bracket 9. By setting the preset spacing, the centerless grinder can adapt to workpieces of different diameters, lengths, and processing requirements, thus expanding the application range of the grinder. Furthermore, by reasonably setting the preset spacing and adopting appropriate adjustment methods, the relative position between the guide wheel and the grinding wheel can be precisely controlled, ensuring the accuracy and stability of the grinding process. The specific value of the preset spacing is not specifically limited in this application and can be set according to actual conditions.

[0060] Optionally, the center of the guide wheel on the guide wheel spindle system 2 and the center of the grinding wheel on the grinding wheel spindle system 1 are both mounted on the upper end surface of the bracket 9 as the mounting reference surface.

[0061] In this embodiment, the upper surface of the bracket 9 is used as the mounting reference surface for both the center of the guide wheel and the center of the grinding wheel. This unifies the mounting reference of the system, which helps to eliminate errors caused by different reference surfaces, thereby ensuring the relative positional accuracy between the guide wheel and the grinding wheel.

[0062] Specifically, by using the upper surface of bracket 9 as a reference, the installation process of guide wheel spindle system 2 and grinding wheel spindle system 1 becomes more standardized and regulated. Installers do not need to consider multiple different reference surfaces separately; they only need to position and install based on the upper surface of bracket 9, which greatly simplifies the installation steps and reduces installation time. At the same time, in the subsequent debugging process, due to the unified reference, it is also easier to adjust and calibrate the position of the guide wheel and grinding wheel, thus improving debugging efficiency.

[0063] Optionally, the center height of the first opening 10 and the center height of the second opening 11 are set on the same straight line.

[0064] In this embodiment, when the center heights of the first opening 10 and the second opening 11 are on the same straight line, this helps to ensure the coaxiality and parallelism between the guide wheel frame mounting body 3 and the guide wheel spindle system 2, and facilitates the adjustment of the end face parallelism difference between the grinding wheel center and the guide wheel center through the eccentric rotary shaft 4.

[0065] Optionally, the eccentric rotary shaft 4 is provided with a connection port, the size of which is adapted to the end size of the eccentric shaft set screw 5.

[0066] In this embodiment, the eccentric shaft set screw 5 is a key component for fixing the position of the eccentric rotary shaft 4. By cooperating with the eccentric rotary shaft 4, the eccentric shaft set screw 5 can firmly lock the current position of the eccentric shaft and prevent it from moving accidentally during equipment operation.

[0067] A connection port is provided on the eccentric rotary shaft 4. When the size of this connection port is adapted to the end size of the eccentric shaft set screw 5, a tight fit is ensured between the rotary shaft and the eccentric shaft set screw 5. This tight fit prevents slippage during tightening or loosening of the screw, allowing the operator to accurately apply torque and smoothly complete the installation and removal of the eccentric shaft set screw 5. For example, if the connection port size is too large, the tool may wobble inside the port, resulting in ineffective torque transmission and potentially damaging the screw or tool. Conversely, if the connection port size is too small, the tool may not be fully inserted, also affecting operation.

[0068] Appropriate dimensional matching can improve the anti-loosening performance of screws. During equipment operation, screws may loosen due to factors such as vibration. Matching the connection port and screw end size can increase the friction between the screw and the installation tool, making the screw more secure after tightening and less prone to loosening, thereby ensuring the stability of the eccentric rotary shaft 4 position.
