Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically an axial floating grinding device. Background Technology

[0002] A grinding device is a mechanical device used to process the surface of a workpiece. Its main function is to remove excess material, burrs, rust, or other uneven parts from the surface of the workpiece through physical friction, thereby achieving the flattening, smoothing, or shaping of the workpiece surface.

[0003] Existing grinding equipment typically uses a fixed grinding structure when processing workpieces, which cannot adaptively adjust to changes in the surface height of the workpiece. When the grinding tool contacts the workpiece surface, the lack of an effective floating compensation mechanism easily leads to problems such as excessive or insufficient local pressure. This not only results in uneven grinding and low efficiency, but also damages the workpiece surface due to over-grinding, affecting the quality stability of the final product. This rigid connection method also requires operators to frequently adjust the grinding angle and force during use, increasing operational complexity and labor intensity, and reducing overall production efficiency.

[0004] Therefore, this utility model provides an axial floating grinding device to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This invention provides an axial floating grinding device, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an axial floating grinding device, comprising a connecting base, a support frame fixedly connected to the bottom of the inner cavity of the connecting base, a connecting shaft fixedly connected to the top of the support frame, a main shaft fixedly connected to the top of the connecting shaft, a grinding tool fixedly connected to the upper surface of the main shaft, a floating adjustment shaft sleeved on the outer surface of the main shaft, sliding sleeves fixedly connected to both sides of the outer surface of the floating adjustment shaft, a spring element fixedly connected to the inner cavity of the sliding sleeve, a connecting cover fixedly connected to the top of the connecting base, two placement grooves opened at the bottom of the connecting cover, a telescopic rod fixedly connected to the top of the inner cavity of the placement groove, and a spring sleeved on the outer ring of the telescopic rod.

[0009] As a preferred technical solution of this application, one side of the outer surface of the spring element is slidably connected to the inner wall of the adjacent support frame and connecting shaft, and the bottom end of the telescopic rod is fixedly connected to the top of the corresponding sliding sleeve.

[0010] As a preferred technical solution of this application, one end of the spring is fixedly connected to the inner wall of the corresponding placement groove, and the other end of the spring is fixedly connected to one side of the corresponding sliding sleeve.

[0011] As a preferred technical solution of this application, guide plates are provided on both sides of the outer surface of the spindle, and slide frames are fixedly connected to both sides of the top of the connecting cover. A slider is slidably connected to the inner cavity of the slide frame, and one end of the slider is fixedly connected to one side of the corresponding guide plate through a connecting plate.

[0012] As a preferred technical solution of this application, mounting plates are fixedly connected to both sides of the outer surface of the guide plate, and a number of bolts are provided on one side of the mounting plate.

[0013] As a preferred technical solution of this application, one end of the bolt passes through one side of two corresponding mounting plates in sequence by threads, and the outer ring of the bolt is fitted with a fastening bolt by threads, and one side of the fastening bolt is in contact with one side of the adjacent mounting plate.

[0014] (III) Beneficial Effects

[0015] By utilizing the slight deformation of the spring, the extension and retraction of the telescopic rod, and the vibration linkage mechanism between the floating adjustment shaft and the main shaft, the problem of being unable to adaptively adjust according to changes in the height of the workpiece surface is effectively solved. This floating compensation mechanism allows the grinding tool to automatically adjust the grinding force and position according to the actual shape of the workpiece surface, avoiding uneven grinding caused by excessive or insufficient local pressure. Operators do not need to frequently adjust the grinding angle and force during use, improving grinding efficiency, ensuring the flatness and smoothness of the workpiece surface, and enhancing the quality stability of the final product.

[0016] The guide plate, slider, slide frame, mounting plate, bolts and fasteners provide reliable protection and guidance for the spindle, the core component of the grinding device. This protective and guiding structure not only prevents the spindle from being damaged by accidental collisions or improper operation during grinding, but also ensures the stability of the spindle during operation, reduces grinding deviations caused by spindle shaking or deviation from the normal trajectory, and further improves grinding accuracy and efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides an axial floating grinding device, such as Figures 1-4 As shown, the technical solution includes a connecting base 1, a support frame 6 fixedly connected to the bottom of the inner cavity of the connecting base 1, a connecting shaft 7 fixedly connected to the top of the support frame 6, a main shaft 4 fixedly connected to the top of the connecting shaft 7, a grinding tool 5 fixedly connected to the upper surface of the main shaft 4, a floating adjustment shaft 8 sleeved on the outer surface of the main shaft 4, sliding sleeves 9 fixedly connected to both sides of the outer surface of the floating adjustment shaft 8, a spring element 10 fixedly connected to the inner cavity of the sliding sleeve 9, a connecting cover 3 fixedly connected to the top of the connecting base 1, two placement grooves 11 opened at the bottom of the connecting cover 3, a telescopic rod 12 fixedly connected to the top of the inner cavity of the placement groove 11, and a spring 13 sleeved on the outer ring of the telescopic rod 12.

[0025] One side of the outer surface of the spring element 10 is slidably connected to the inner wall of the adjacent support frame 6 and connecting shaft 7. The bottom end of the telescopic rod 12 is fixedly connected to the top of the corresponding sliding sleeve 9. Through the sliding connection between the spring element 10 and the inner wall of the support frame 6 and connecting shaft 7, and the fixed connection between the telescopic rod 12 and the sliding sleeve 9, the grinding tool 5 can better adapt to the unevenness of the surface of the workpiece during operation. The sliding connection of the spring element 10 can buffer the radial force on the spindle 4 during grinding, while the fixed connection of the telescopic rod 12 ensures the stability of the sliding sleeve 9. This structural combination allows the device to automatically adjust the position of the grinding tool 5 during grinding, avoiding excessive pressure on the grinding tool 5 due to the unevenness of the surface of the workpiece, thereby extending the service life of the grinding tool 5 and ensuring the uniformity of grinding.

[0026] One end of the spring 13 is fixedly connected to the inner wall of the corresponding placement groove 11, and the other end of the spring 13 is fixedly connected to one side of the corresponding sliding sleeve 9. Through the fixed connection between the spring 13 and the inner wall of the placement groove 11 and the sliding sleeve 9, when the grinding tool 5 contacts the surface of the workpiece, the spring 13 will undergo elastic deformation, thereby driving the sliding sleeve 9 to move axially, so that the grinding tool 5 can automatically adjust the grinding force according to the height change of the surface of the workpiece.

[0027] Guide plates 2 are provided on both sides of the outer surface of the spindle 4, and sliding frames 19 are fixedly connected to both sides of the top of the connecting cover 3. A slider 14 is slidably connected to the inner cavity of the sliding frame 19. One end of the slider 14 is fixedly connected to one side of the corresponding guide plate 2 through the connecting plate 15. Through the arrangement of the guide plate 2, sliding frame 19, slider 14 and connecting plate 15, the spindle 4 can be effectively guided and protected. The guide plate 2 can be adjusted as needed by sliding the slider 14 in the inner cavity of the sliding frame 19, so as to tightly fit or loosen the spindle 4. This not only prevents the spindle 4 from deviating from the normal working trajectory due to external force during the grinding process, but also allows for quick positioning and fixing of the spindle 4 when needed, improving the stability and reliability of the device, and reducing grinding deviation caused by the shaking of the spindle 4.

[0028] Mounting plates 17 are fixedly connected to both sides of the outer surface of the guide plate 2. Several bolts 18 are provided on one side of the mounting plate 17. By setting mounting plates 17 and bolts 18 on both sides of the outer surface of the guide plate 2, the guide plate 2 can be quickly fixed and adjusted. The mounting plate 17 provides the installation position for the bolts 18, so that the operator can adjust the position and tightness of the guide plate 2 by tightening or loosening the bolts 18, which facilitates the connection of the corresponding two guide plates 2.

[0029] One end of the bolt 18 passes through one side of two corresponding mounting plates 17 in sequence via threads. The outer ring of the bolt 18 is fitted with a fastening bolt 16 via threads. One side of the fastening bolt 16 is in contact with one side of the adjacent mounting plate 17. Through the cooperation of the bolt 18 and the fastening bolt 16, the guide plate 2 can be firmly fixed. The bolt 18 passes through the two mounting plates 17 and is further tightened by the fastening bolt 16, so that the guide plate 2 can fit tightly against the spindle 4, thereby providing a stable guiding effect for the grinding process. The setting of the fastening bolt 16 not only increases the fastening strength of the bolt 18, but also prevents the bolt 18 from loosening due to vibration during the grinding process.

[0030] Specifically: When personnel use the device, firstly, the grinding tool 5 is installed at the front end of the spindle 4, and the grinding device is started; when the grinding tool 5 contacts the workpiece to be ground, due to the unevenness of the workpiece surface, the grinding tool 5 is subjected to opposing forces of different directions and magnitudes from the workpiece surface; at this time, under the connection of the sliding sleeve 9, the spring 13 will undergo slight deformation according to the force, thereby driving the telescopic rod 12 to produce corresponding telescopic movements, so that the floating adjustment shaft 8 can generate slight vibrations in the axial direction. At the same time, the spring element 10 slides in the inner cavity of the support frame 6 and the connecting shaft 7, so that the floating adjustment shaft 8 can more sensitively adapt to changes in the workpiece surface, and the floating adjustment... The vibration of the joint shaft 8 is transmitted to the grinding tool 5 through the main shaft 4, enabling the grinding tool 5 to automatically adjust the force applied according to the undulations of the workpiece surface during the grinding process, effectively avoiding the problem of excessive or insufficient local pressure. The operator pushes the two sliders 14, which slide along the inner cavity of the slide frame 19, thereby driving the two guide plates 2 to move closer to each other until they are tightly fitted. The corresponding two mounting plates 17 are then in contact. The operator passes the bolts 18 through the corresponding mounting plates 17 and fixes them with threads, and uses fastening bolts 16 for secondary reinforcement to ensure the stability between the guide plates 2. The tight fit of the guide plates 2 provides good guiding support for the main shaft 4, improving the stability and accuracy of the entire grinding process.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
