Description

Technical Field

[0001] The present application relates to the field of equipment manufacturing technology, and more particularly to a device for adjusting the center height and end face of a guide wheel of a centerless grinder and a centerless grinder. Background Art

[0002] On a centerless grinder, the grinding wheel and guide wheel spindle system are the key functional components of the grinder. 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 on the vertical plane of the fixed body. At the same time, after the machine tool is assembled, the grinding wheel and the guide wheel spindle center need to be adjusted to the same height as the bracket installation reference plane, and the front end face of the guide wheel must be adjusted to be lower than the end face of the grinding wheel.

[0003] In existing processing technology, installing a rotary centering axis on the fixed body only satisfies the guide wheel frame's rotational function and only enables height adjustment from the spindle center to the bracket mounting reference surface. The parallel tolerance between the guide wheel end face and the grinding wheel end face cannot be adjusted. Typically, after final assembly measurement, the guide wheel spindle system's adjustment shims and the guide wheel chuck's thickness are machined back to ensure height alignment and end face flushness meet standard requirements. Therefore, in actual production, this structure not only suffers from low production efficiency but also large adjustment accuracy errors, failing to meet existing processing requirements.

[0025] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in this application. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] In existing processing technology, installing a rotary centering axis on the fixed body only satisfies the rotation function of the guide wheel frame. It cannot adjust the height tolerance between the guide wheel spindle center and the bracket mounting reference plane, nor the parallel tolerance between the guide wheel end face and the grinding wheel end face. Generally, after final assembly measurement, adjustment shims are added to the grinding wheel spindle system and the thickness of the guide wheel chuck is turned to ensure that the height and end face are flush to the standard requirements. Therefore, in actual production, this structure not only has low production efficiency but also has large adjustment accuracy errors, which cannot meet existing processing requirements.

[0027] Based on this, the present 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 realizes the grinding angle rotation through an eccentric rotating shaft. The eccentric rotating shaft is installed with a centering slider, and the axial displacement adjustment of the guide wheel spindle system is realized through a slider displacement adjustment device. Compared with the traditional adjustment method, the combined adjustment device realizes the rapid and precise adjustment of the center height and end face parallelism difference of the guide wheel and the 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] See also Figures 1 to 9, the first aspect of the present application provides a combined adjustment device for the center height and end face of the grinding wheel guide wheel of a centerless grinder, the device comprising: an eccentric rotating shaft 4, an eccentric shaft set screw 5, a centering slider 8, a slider displacement adjustment screw 6 and an adjustment screw fixing frame 7; the eccentric rotating shaft 4 is installed between the guide wheel frame mounting fixed body 3 and the guide wheel spindle system 2 of the centerless grinder, and 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 rotating shaft 4 together; the centering slider 8 and the slider displacement adjustment screw 6 are Installed in the guide wheel frame mounting fixed body 3, the eccentric rotating shaft 4 and the centering slider 8 are connected to the guide wheel spindle system 2, one end of the slider displacement adjustment screw 6 is connected to the centering slider 8, and the other end of the slider displacement adjustment screw 6 extends out of the guide wheel frame mounting fixed body 3 and is connected to the adjustment screw fixing frame 7; the eccentric rotating shaft 4 is used to adjust 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 to the same height, and the centering slider 8 cooperates with the slider displacement adjustment screw 6 and the adjustment screw fixing frame 7 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 role and function of each component of this application are explained: Eccentric rotating shaft 4: The eccentric rotating shaft 4 is a shaft-type part with an eccentric design. Its axis centerline does not coincide with the axis centerline of the outer cylindrical surface, and there is a certain eccentricity. The eccentric rotating shaft 4 is installed between the guide wheel frame mounting fixed body 3 and the guide wheel spindle system 2 of the centerless grinder. By rotating the eccentric rotating 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 accurate and adjustable, and can meet the height matching requirements under different grinding needs.

[0030] Eccentric shaft set screw 5: The eccentric shaft set screw 5 has a fastening function and is provided with threads and a head for fixing or locking other components. The eccentric shaft set screw 5 is provided on the guide wheel spindle system 2 and is used for fastening the eccentric rotating shaft 4. After adjusting the position of the eccentric rotating shaft 4, by tightening the eccentric shaft set screw 5, the eccentric rotating shaft 4 can be prevented from being offset due to vibration or external force, thereby ensuring the stability of the guide wheel and the center height of the grinding wheel.

[0031] Centering slider 8: The centering slider 8 has a sliding function. The centering slider 8 is installed in the guide wheel frame mounting body 3 and is 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 adjustment screw 6: This is a threaded rod-shaped component, one end of which is connected to the centering slider 8. The other end extends out of the guide wheel frame mounting fixture 3 and is connected to the adjustment screw fixture 7. By rotating the slider displacement adjustment screw 6, its relative position with the centering slider 8 can be changed, thereby achieving displacement adjustment of the centering slider 8. This adjustment method is precise and controllable, and can meet the requirements for end face parallelism adjustment under different grinding requirements.

[0033] Adjustment screw holder 7: This component secures and supports the slider displacement adjustment screw 6. It has a threaded hole that mates with the slider displacement adjustment screw 6. Mounted on the guide wheel frame mounting fixture 3, it serves as a carrier for controlling the slider displacement adjustment screw 6. The adjustment screw holder 7 ensures the stability and accuracy of the slider displacement adjustment screw 6 during adjustment, thereby improving the reliability and precision of the entire adjustment device.

[0034] Therefore, the center height and end face combined adjustment device of the centerless grinder grinding wheel guide wheel of the present application realizes the rapid and precise adjustment of the guide wheel and grinding wheel center height and end face parallelism difference through the coordinated work of various components compared with the traditional adjustment method. It can greatly simplify the adjustment process, reduce manual intervention and debugging time, and thus improve production efficiency.

[0035] The center height and end face combined adjustment device of the grinding wheel guide wheel of the centerless grinder is based on the principle of adjusting the height of the guide wheel and the grinding wheel center through the coordination of various components: Specifically, the center height H1 of the installation reference plane of the centerless grinder grinding wheel spindle system 1 to the bracket 9, the center height H2 of the installation reference plane of the guide wheel spindle system 2 to the bracket 9, and the parallel dimensions of the grinding wheel and the guide wheel end faces 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 center of the grinding wheel, the operator uses a wrench to rotate the eccentric rotating shaft 4. Due to the eccentricity of the eccentric rotating shaft 4, as it rotates, the guide wheel spindle system 2 will produce a small displacement in the up and down directions around a virtual rotation center. By precisely controlling the rotation angle of the eccentric rotating shaft 4, the operator can gradually adjust the position of the guide wheel spindle system 2 to gradually reduce the height difference between the guide wheel center and the grinding wheel center until they reach the same height state.

[0036] Specifically, first place the eccentric rotating shaft 4 in a horizontal position. Using a dedicated centerless grinder inspection fixture, 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, use a hexagonal wrench to adjust the eccentric rotating shaft 4 clockwise. By rotating the eccentric rotating shaft 4 to the desired eccentricity, adjust the guide wheel center and the grinding wheel center to the same height to meet dimensional accuracy requirements. If H1

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

[0038] When the operator rotates the slider displacement adjustment screw 6, due to the fixed fit between the screw and the adjustment screw fixing frame 7, the slider displacement adjustment screw 6 can be driven to rotate by rotating the adjustment screw fixing frame 7. At the same time, the rotation of the slider displacement adjustment screw 6 will drive the centering slider 8 connected to it to move linearly in the guide wheel frame mounting fixed body 3. The linear movement of the centering slider 8 will drive the guide wheel spindle system 2 to move horizontally, thereby achieving the parallel difference between the grinding wheel and the guide wheel center end face.

[0039] Specifically, move the centerless grinder feed saddle 12, use a depth gauge to measure the parallel tolerance H3 between the end face of the grinding wheel and the end face of the guide wheel, adjust the screw 6 by sliding the slider, and adjust the lateral movement of the centering slider 8, such as Figure 5 , thereby realizing the end face adjustment of the grinding wheel spindle system 1 and the guide wheel spindle system 2.

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

[0041] In the embodiment of the present application, a first opening 10 and a second opening 11 are respectively provided on the guide wheel frame mounting fixed body 3 and the guide wheel spindle system 2, and the eccentric rotating 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 rotating shaft 4 and the position adjustment of the guide wheel spindle system 2 relative to the guide wheel frame mounting fixed body 3, thereby achieving the adjustment goal of the guide wheel and the grinding wheel center being equal in height.

[0042] ​Among them, the first opening 10 is opened on the guide wheel frame mounting fixed body 3, and its shape and size are adapted to the eccentric rotating shaft 4. The first opening 10 is a circular hole, and its diameter is larger than the maximum outer diameter of the eccentric rotating shaft 4 to ensure that the eccentric rotating shaft 4 can be installed smoothly and has a certain amount of activity space, but the activity space is controlled within a reasonable range to prevent the eccentric rotating shaft 4 from shaking too much during operation.

[0043] The second opening 11 is provided on the guide wheel main shaft system 2 in correspondence with the first opening 10. It is also a circular hole, and its size matches the eccentric rotating shaft 4 to ensure a stable connection and normal transmission between the eccentric rotating shaft 4 and the guide wheel main shaft system 2. The position of the second opening 11 is precisely aligned with the first opening 10, allowing the eccentric rotating shaft 4 to pass through the first opening 10 and the second opening 11 simultaneously, achieving connection and relative position adjustment between the guide wheel frame mounting body 3 and the guide wheel main shaft system 2.

[0044] In actual work, when it is necessary to adjust the guide wheel to the same height as the center of the grinding wheel, the operator rotates the eccentric rotating shaft 4. Due to the eccentric design of the eccentric rotating shaft 4, its axis line does not coincide with the axis line of the outer cylindrical surface, and there is a fixed eccentric distance. During the rotation process, the contact point between the eccentric rotating shaft 4 and the first opening 10 and the second opening 11 will change, resulting in a slight displacement of the guide wheel spindle system 2 in the up and down directions relative to the guide wheel frame mounting fixed body 3. By precisely controlling the rotation angle of the eccentric rotating shaft 4, the height difference between the guide wheel center and the grinding wheel center can be fine-tuned, and finally the two can reach the same height state.

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

[0046] Optionally, a screw mounting port is provided on the guide wheel spindle system 2, and the screw mounting port is obliquely arranged on the second opening 11 and passes through the second opening 11, and the eccentric shaft fastening screw 5 is installed in the screw mounting port.

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

[0048] Specifically, the screw mounting opening is tilted relative to 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 tilt allows the eccentric shaft set screw 5 to apply pressure to the eccentric rotating shaft 4 from a specific direction when tightened, thereby enhancing the securing effect. When the eccentric shaft set screw 5 is installed in the screw mounting opening, it comes into close contact with the eccentric rotating shaft 4 when tightened, thereby securing the eccentric rotating shaft 4 to the guide wheel spindle system 2.

[0049] In the embodiment of the present application, after the guide wheel and the grinding wheel center height are adjusted to the appropriate position, the operator uses a tool to tighten the eccentric shaft set screw 5. Due to the inclined setting of the screw mounting opening, as the eccentric shaft set screw 5 is tightened, the end of the eccentric shaft set screw 5 will apply pressure to the eccentric rotating shaft 4 from the inclined direction. This inclined pressure will generate a component force acting in the rotation direction of the eccentric rotating shaft 4, which can effectively prevent the eccentric rotating shaft 4 from rotating during the operation of the centerless grinder. At the same time, the threaded fit between the eccentric shaft set screw 5 and the inner wall of the screw mounting opening 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, which ensures the stability of the guide wheel and the center height of the grinding wheel.

[0051] Optionally, a feed saddle 12 is provided on the guide wheel frame mounting fixed 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 the embodiment of the present application, 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 to realize the feed movement of the guide wheel spindle system 2 in a specific direction. This feed movement can accurately adjust the relative position between the guide wheel and the grinding wheel, thereby controlling the grinding size 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 by 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 factors such as vibration on the grinding accuracy.

[0054] Among them, the guide wheel frame mounting fixed body 3 is a structure used to fix and support the guide wheel related components in the centerless grinder, and the feed saddle 12 is installed on the guide wheel frame mounting fixed body 3, and at the same time cooperates with the bracket 9, and is located between the guide wheel frame mounting fixed body 3 and the bracket 9. The feed saddle 12 is fixed together with the guide wheel frame mounting fixed body 3, but can realize relative movement on the bracket 9.

[0055] Among them, the guide wheel spindle system 2 is set 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, has a large bottom area and high strength, and its surface cooperates with the feed saddle 12. The bracket 9 is provided with a guide rail or slide groove that matches 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 to provide 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 , slight adjustments to the guide wheel position can be achieved, thereby achieving end face adjustment of the grinding wheel spindle system 1 and the guide wheel spindle system 2 .

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

[0059] In the embodiment of the present application, the preset spacing can be adjusted by adjusting the position of the guide wheel frame mounting fixture 3 on the centerless grinder bed, or 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, expanding the application range of the grinder. And by reasonably setting the preset spacing and adopting the corresponding adjustment method, the relative position between the guide wheel and the grinding wheel can be accurately controlled to ensure the accuracy and stability of the grinding process. Among them, 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 both use the upper end surface of the bracket 9 as the installation reference surface.

[0061] In the embodiment of the present application, the upper end surface of the bracket 9 is used as the installation reference surface for both the guide wheel center and the grinding wheel center, which can unify the installation reference of the system. This helps to eliminate errors caused by different reference surfaces, thereby ensuring the relative position accuracy between the guide wheel and the grinding wheel.

[0062] Specifically, the upper end surface of the bracket 9 is used as a reference, making the installation process of the guide wheel spindle system 2 and the grinding wheel spindle system 1 more standardized and normalized. The installer does not need to consider multiple different reference surfaces separately, but only needs to position and install according to the upper end surface of the bracket 9, which greatly simplifies the installation steps and reduces the 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 the grinding wheel, thereby improving the debugging efficiency.

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

[0064] In the embodiment of the present application, 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 fixture 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 rotating shaft 4.

[0065] Optionally, a connecting port is provided on the eccentric rotating shaft 4 , and the size of the connecting port is adapted to the size of the end of the eccentric shaft set screw 5 .

[0066] In the embodiment of the present application, the eccentric shaft locking screw 5 is a key component for fixing the position of the eccentric rotating shaft 4. The eccentric shaft locking screw 5 can firmly lock the current position of the eccentric shaft by cooperating with the eccentric rotating shaft 4 to prevent it from accidentally moving during the operation of the equipment.

[0067] The eccentric shaft 4 is provided with a connection port. When the size of the connection port matches the end size of the eccentric shaft set screw 5, a tight fit is ensured between the eccentric 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 is too large, the tool may wobble within the connection port, resulting in an inability to effectively transmit torque and even damage to the screw or tool. If the connection port is too small, the tool may not be fully inserted, which also affects the operation.

[0068] The anti-loosening performance of the screw can be improved by matching the appropriate size. During the operation of the equipment, the screw may become loose due to the influence of factors such as vibration. The matching connection port and the screw end size can increase the friction between the screw and the installation tool, making the screw more secure after tightening and not easy to loosen, thereby ensuring the stability of the position of the eccentric rotating shaft 4.
