Description

Technical Field

[0001] This utility model relates to the technical field of honing equipment, and in particular to a honing head concentricity adjustment mechanism. Background Technology

[0002] Honing is a precision hole machining process that uses a honing head to precisely machine the inner hole of a workpiece in order to improve the dimensional accuracy, surface quality, and geometric accuracy of the hole.

[0003] During the use of a honing head, it is necessary to connect the honing head to the spindle so that the honing head can be driven to hone the inside of the workpiece. After the honing head and the spindle are connected, the concentricity of the honing head and the spindle needs to be adjusted so that the honing head and the spindle are always in a horizontal straight line. If the concentricity of the honing head and the spindle is not good, it will lead to problems such as the inner hole of the workpiece after processing, affecting the processing accuracy and quality of the workpiece.

[0004] However, the existing honing head concentricity adjustment method is relatively complicated and the adjustment process is cumbersome, requiring operators to have a high level of skill and rich experience. Each honing head adjustment requires a lot of time, resulting in low honing head concentricity adjustment efficiency.

[0005] Therefore, we provide a honing head concentricity adjustment mechanism. Utility Model Content

[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.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: A honing head concentricity adjustment mechanism, such as... Figures 1-4 As shown, it includes a honing head 1, one end of which is connected to a spindle 2. A first external threaded cylinder 3 is fixedly installed on the outer surface of the spindle 2, and a concentricity adjustment component 4 is connected to the outside of the first external threaded cylinder 3.

[0026] The concentricity adjustment assembly 4 includes a screw cylinder 401 sleeved on the outside of the first external threaded cylinder 3. A rotating ring 402 is slidably connected to the outer surface of the screw cylinder 401. Several arc-shaped adjustment grooves 403 are opened through one side surface of the rotating ring 402. An adjustment rod 404 is provided inside the arc-shaped adjustment groove 403. An arc-shaped adjustment block 405 is connected to the outer end of the adjustment rod 404. Two fixed disks 407 are symmetrically installed on the outer surface of the screw cylinder 401. Several limiting grooves 408 are opened through one side surface of the fixed disk 407. The inner end of the adjustment rod 404 slides inside the limiting groove 408.

[0027] The main shaft 2 and the first external threaded cylinder 3 are concentrically designed. The first external threaded cylinder 3 and the screw cylinder 401 are connected by a threaded engagement. The rotating ring 402 is located between the two fixed disks 407.

[0028] The rotating ring 402 and the arc-shaped adjustment groove 403 are concentric with the main shaft 2. The arc-shaped adjustment groove 403 is equidistantly distributed around the circumference and is inclined from the outside to the inside. A handle is installed on the outer surface of the rotating ring 402.

[0029] After the honing head 1 is connected to the spindle 2, the screw cylinder 401 is connected to the first external threaded cylinder 3. At this time, the arc-shaped adjusting blocks 405 are evenly arranged outside the honing head 1, the adjusting rod 404 is located at the outermost end of the arc-shaped adjusting groove 403, and the inner end of the adjusting rod 404 is located at the outer end of the limiting groove 408. Several arc-shaped adjusting blocks 405 form the maximum inner diameter. Then, the handle is turned to drive the rotating ring 402 to rotate. Since the adjusting rod 404 can only move vertically inside the limiting groove 408, the adjusting rod 404 will not rotate with the rotating ring 402. When the rotating ring 402 rotates, the arc-shaped adjusting groove 403 rotates synchronously. Under the guidance of the arc-shaped adjusting groove 403, several adjusting rods 404 will drive the arc-shaped adjusting blocks 405 to move inward synchronously. During the inward movement of the arc-shaped adjusting blocks 405, if they come into contact with the outer surface of the honing head 1... Stop rotating the rotating ring 402. At this time, observe the distance between the honing head 1 and the arc-shaped adjusting block 405, and adjust the honing head 1 so that it is aligned with the uncontacted arc-shaped adjusting block 405. Then, continue rotating the rotating ring 402 so that the arc-shaped adjusting block 405 continues to move inward. Repeat the operation until the honing head 1 contacts the inner edge of the arc-shaped adjusting block 405 simultaneously, thus completing the concentricity adjustment of the honing head 1. Under the action of the concentricity adjustment component 4, the operator does not need to have a high level of skill or rich experience to quickly complete the concentricity adjustment of the honing head 1, ensuring that the honing head 1 and the spindle 2 are always on the same horizontal line. Moreover, the operation process is simple and convenient, and the time required is greatly reduced compared to conventional concentricity adjustment mechanisms, further improving the efficiency of the concentricity adjustment of the honing head 1.

[0030] like Figures 1-4 As shown, several support and limiting grooves 410 are evenly provided on the outer end surfaces of the two fixed disks 407. A slider 409 is slidably arranged inside the support and limiting groove 410. The slider 409 is fixedly connected to the adjusting rod 404. The inner end surface of the slider 409 is in contact with the outer end surface of the fixed disk 407.

[0031] Under the limiting action of slider 409 and support limiting groove 410, firstly, the angle of adjusting rod 404 can be limited to prevent the adjusting rod 404 from rotating during movement, thus avoiding the problem that the arc-shaped adjusting block 405 and the honing head 1 cannot fit together. Secondly, the horizontal position of adjusting rod 404 can be limited to ensure that adjusting rod 404 is always in a horizontal state, thus ensuring the stability of adjusting rod 404 during operation.

[0032] like Figures 1-4 As shown, an annular groove 411 is provided on the outer surface of the screw barrel 401, and several arc-shaped sliders 412 are slidably arranged inside the annular groove 411. The several arc-shaped sliders 412 are distributed equidistantly around the circumference.

[0033] The outer surface of the arc-shaped slider 412 is tightly fitted to the inner wall of the annular groove 411, and several arc-shaped sliders 412 are simultaneously fixedly connected to the inner side of the rotating ring 402.

[0034] When the rotating ring 402 is rotated by the handle, the rotating ring 402 will drive the arc-shaped slider 412 to move inside the annular groove 411. Under the action of the annular groove 411 and the arc-shaped slider 412, firstly, the position of the rotating ring 402 can be limited to ensure the stability of the rotating ring 402 during rotation. Secondly, based on the tight fit between the arc-shaped slider 412 and the inner wall of the annular groove 411, the annular groove 411 can limit the arc-shaped slider 412 to prevent the rotating ring 402 from rotating too fast. Moreover, the annular groove 411 can keep the rotating ring 402 in a certain position, which is convenient for adjusting the honing head 1.

[0035] Figures 1-4 As shown, a second external threaded cylinder 5 is connected to the outer surface of the main shaft 2. The second external threaded cylinder 5 is located at the end of the main shaft 2 and is threadedly connected to the screw cylinder 401.

[0036] After the concentricity adjustment component 4 has adjusted the concentricity of the spindle 2 and the honing head 1, the screw cylinder 401 is unscrewed from the first external threaded cylinder 3, and then the screw cylinder 401 is rotated and installed on the second external threaded cylinder 5. At this time, the concentricity adjustment component 4 is located at the end of the spindle 2. Under the action of the second external threaded cylinder 5, the concentricity adjustment component 4 can be installed and fixed after use, so as to avoid the concentricity adjustment component 4 from affecting the use of the honing head 1. At the same time, the position of the concentricity adjustment component 4 can be limited to prevent the concentricity adjustment component 4 from sliding on the spindle 2, thus ensuring the stability of the honing head 1.

[0037] 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.
