Description

Technical Field

[0001] This utility model relates to the field of grooving processing, and more specifically to a high-precision positioning grooving processing device. Background Technology

[0002] Grooving is a machining process that creates narrow grooves or cuts on a workpiece by removing material. Common grooving methods involve using a rotating tool (such as a milling cutter) to cut into the clamped workpiece, forming the desired groove shape. During grooving, the rotating tool typically only rotates, and the tool depth is fed by a mechanism that drives the clamping tool to move along its axis. Now, further advancements have been made to drive the rotating tool to move linearly on a horizontal plane, enabling grooving. However, existing grooving devices cannot stably clamp circular plate-shaped parts for grooving. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a high-precision positioning and grooving processing device, which can clamp a circular plate-shaped part by simultaneously gathering multiple clamping blocks with protrusions, thereby increasing the accuracy of grooving processing.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A high-precision positioning and grooving processing device includes a support structure for fixing and a rotary structure rotatably connected to the support structure. The rotary structure is provided with multiple clamping structures, which are evenly distributed on the edge of the rotary structure to clamp a circular plate synchronously from multiple directions. The middle part of the rotary structure is provided with an adjustment structure for supporting the lifting and lowering of the circular plate. The upper part of the adjustment structure is correspondingly provided with a milling structure capable of vertical feed and linear movement. Each clamping structure is provided with a clamping block for fixing the circular plate. Each clamping block is fan-shaped, and multiple protrusions are provided on the surface of each clamping block that clamps the circular plate.

[0006] Furthermore, the multiple protrusions on each clamping block are all arc-shaped.

[0007] Furthermore, the diameter of the multiple arc-shaped protrusions on each clamping block increases sequentially from the center to both sides.

[0008] Furthermore, each protrusion has a through hole in the center.

[0009] Furthermore, each clamping structure also includes a rectangular rod fixed to the outer wall of the clamping block, a sliding plate slidably connected to each rectangular rod, an upper pressure plate fixed to each sliding plate, the lower end face of each upper pressure plate fitting against the upper end face of the clamping block, an installation frame sleeved on each rectangular rod, a follower plate fixed to each installation frame, and multiple springs provided between each follower plate and the sliding plate.

[0010] Furthermore, the rotary structure includes a turntable capable of rotating around its own axis and multiple vertical plates fixed to the edge of the turntable. Each vertical plate has a through hole 1 in the middle and two ear plates symmetrically arranged on both sides of each vertical plate. Each ear plate has a through hole 2. Each clamping structure also includes two guide rods fixed to the follower plate and passing through the corresponding two through holes 2, and a cylinder 1 fixed to the vertical plate and passing through the through hole 1 and fixedly connected to the follower plate.

[0011] Furthermore, the adjustment structure includes multiple cylinders two fixedly connected to the middle of the rotary structure. Support plates are fixedly connected to the cylinder rods of the multiple cylinders two. The support plates are annular, and the outer contour of each cylinder two is located between the inner diameter and the outer diameter of the annular support plate.

[0012] Furthermore, a rubber sheet is attached to each protrusion.

[0013] Furthermore, the plurality of clamping structures is at least three.

[0014] Furthermore, at least three of the plurality of clamping blocks move synchronously.

[0015] The advantages of this high-precision positioning and grooving processing device are as follows: it can clamp the circular plate-shaped part by simultaneously gathering multiple clamping blocks with protrusions, thereby increasing the accuracy of grooving processing; it can also clamp the circular plate-shaped part more firmly by deforming multiple protrusions; and it can also limit the movement from the upper and lower parts of the circular plate-shaped part to prevent shaking when milling the edge of the part.

Detailed Implementation

[0024] refer to Figure 1 , 2 Examples 3, 4, 5, and 6 detail the implementation of grooving on a fixed circular plate:

[0025] A high-precision positioning and grooving processing device includes a support structure for fixing and a rotary structure rotatably connected to the support structure. The rotary structure is provided with multiple clamping structures, which are evenly distributed on the edge of the rotary structure to clamp a circular plate synchronously from multiple directions. The middle part of the rotary structure is provided with an adjustment structure for supporting the lifting and lowering of the circular plate. The upper part of the adjustment structure is correspondingly provided with a milling structure capable of vertical feed and linear movement. Each clamping structure is provided with a clamping block 52 for fixing the circular plate. Each clamping block 52 is fan-shaped, and multiple protrusions 53 are provided on the surface of each clamping block 52 clamping the circular plate.

[0026] The milling structure is a rotating milling cutter on a milling machine in the prior art, and a structure that drives the milling cutter to perform transverse and longitudinal feed in the vertical direction and horizontal plane. It can drive the milling cutter to rotate to mill a circular plate, can move in the vertical direction to feed the milling depth, and can move in the horizontal direction and longitudinal plane.

[0027] The support structure is used for mounting on a slotting machine tool. The support structure includes a base frame 11 and multiple mounting plates 12 fixedly connected to the circumference of the base frame 11. Each mounting plate 12 has a through hole 3 in the middle, allowing it to be mounted on the slotting machine tool through a portion of the mounting plates 12. The mounting plate is connected to the slotting machine tool by bolts passing through the through holes. A geared motor 13 is fixedly connected to one of the mounting plates 12, and a gear 14 is fixedly connected to the output shaft of the geared motor 13.

[0028] The rotary structure includes a rotary frame 21 rotatably connected to the base frame 11. A gear ring 22 is fixedly connected to the rotary frame 21. The gear ring 22 is used as the power input for the rotary frame 21 to rotate around its own axis. A turntable 23 is fixedly connected to the upper end face of the rotary frame 21. Multiple vertical plates 24 are fixedly connected to the edge of the upper end face of the turntable 23. A through hole 1 is provided in the middle of each vertical plate 24. Two ear plates 25 are symmetrically arranged on both sides of each vertical plate 24. A through hole 2 is provided on each ear plate 25.

[0029] Gear 14 meshes with gear ring 22 for transmission. When turntable 23 needs to rotate, reducer motor 13 is started. The output shaft of reducer motor 13 drives gear 14 to rotate. Gear 14 meshes with and drives gear ring 22 to rotate. Gear ring 22 drives rotary frame 21 to rotate, thereby realizing the rotation of any part on rotary frame 21. Rotary frame 21 drives multiple vertical plates 24 and ear plates 25 to rotate.

[0030] Each clamping structure is equipped with a clamping block 52 that fixes a circular plate. Each clamping block 52 is fan-shaped, and multiple protrusions 53 are provided on the surface of each clamping block 52 that clamps the circular plate. Each clamping structure also includes a rectangular rod 51 fixedly connected to the outer wall of the clamping block 52. A sliding plate 62 is slidably connected to each rectangular rod 51, and an upper pressure plate 63 is fixedly connected to each sliding plate 62. The lower end face of each upper pressure plate 63 is in contact with the upper end face of the clamping block 52. A mounting frame 44 is sleeved on each rectangular rod 51, and a follower plate 42 is fixedly connected to each mounting frame 44. Multiple springs 61 are provided between each follower plate 42 and the sliding plate 62. Each clamping structure also includes two guide rods 43 fixedly connected to the follower plate 42 and passing through two corresponding through holes 2, and a cylinder rod fixedly connected to the vertical plate 24 and passing through through hole 1 and fixedly connected to the follower plate 42.

[0031] The adjustment structure includes multiple cylinders 31 fixedly connected to the middle of the rotary structure. A support plate 32 is fixedly connected to the cylinder rod of the multiple cylinders 31. The support plate 32 is annular, and the outer contour of each cylinder 31 is located between the inner diameter and the outer diameter of the annular support plate 32.

[0032] When it is necessary to slot the circular plate, the circular plate is placed on the support plate 32. The support plate 32 supports the circular plate, and multiple cylinders 31 are activated. The cylinder rods of the multiple cylinders 31 move synchronously to raise and lower the support plate 32. The support plate 32 drives the circular plate to rise and fall, thereby adjusting the vertical position of the slotted circular plate. The annular support plate 32 can stably support the circular plate while allowing debris to be discharged through the central hole and the external through-groove.

[0033] When the support plate 32 adjusts the circular plate until its upper surface coincides with the upper surface of the multiple protrusions 53, multiple cylinders 41 are activated. The cylinder rod of each cylinder 41 drives the follower plate 42 to slide, and the follower plate 42 drives the two guide rods 43 to slide. The guide rods 43 on each ear plate 25 slide inside the through hole, thereby ensuring the stable sliding of the multiple follower plates 42. Each follower plate 42 drives the rectangular rod 51 to slide, and each rectangular rod 51 drives the clamping block 52 to slide. The multiple clamping blocks 52 move towards the axis of the turntable 23 simultaneously, clamping the circular plate on the support plate 32 to fix the circular plate. The multiple protrusions 53 on the surface of each clamping block 52 that clamp the circular plate can increase the pressure when the clamping block 52 clamps the circular plate, which can fix the circular plate more firmly, increase the stability when fixing the circular plate, and increase the accuracy when grooving the circular plate.

[0034] Each sliding plate 62, driven by the spring force of its corresponding multiple springs 61, slides away from the follower plate 42 on the rectangular rod 51. Each sliding plate 62 drives the upper pressure plate 63 to approach the axis of the turntable 23. Multiple upper pressure plates 63 press on the upper end face of the circular plate, thereby limiting the circular plate in the vertical direction through multiple upper pressure plates 63 and support plate 32. The circular plate is fixed by clamping multiple clamping blocks 52, which facilitates the grooving process.

[0035] Each clamping block 52 has multiple protrusions 53 that are arc-shaped. This allows the multiple arc-shaped protrusions 53 to clamp the outer edge of the circular plate, thereby reducing the contact area between the multiple arc-shaped protrusions 53 and the outer edge of the circular plate, further increasing the pressure of the clamping block 52 clamping the circular plate, and enhancing the accuracy of the positioning of the multiple clamping blocks 52 clamping the circular plate.

[0036] The number of clamping structures is at least three, which can clamp the circular plate through more than three clamping structures, thereby positioning and clamping the circular plate through the three clamping blocks 52 in the three clamping structures;

[0037] The maximum number of clamping structures is four. The circular plate is clamped beyond the limit by the four clamping structures. The circular plate is positioned and clamped by the four clamping blocks 52 in the four clamping structures, which enhances the accuracy of positioning the circular plate and ensures the accuracy of grooving when grooving the circular plate.

[0038] The multiple arc-shaped protrusions 53 on each clamping block 52 increase in diameter from the center to both sides. This allows the outer wall of the circular plate to be clamped by the multiple arc-shaped protrusions 53 on each clamping block 52 with increasing diameter. The multiple arc-shaped protrusions 53 on each clamping block 52 can better fit the arc shape of the outer surface of the circular plate, making the multiple clamping blocks 52 fit the circular plate more closely for fixation and providing precise fixation even when the multiple arc-shaped protrusions 53 deform.

[0039] Each protrusion 53 has a through hole 4 in the middle. The through hole 4 increases the deformation range of the protrusion 53, allowing the multiple protrusions 53 to fit more fully against the outer edge of the circular plate when clamping it, further enhancing the stability of the clamping of the circular plate by the multiple clamping blocks 52 and protrusions 53; each clamping block 52 and protrusion 53 is made of elastic material;

[0040] Once the multiple clamping blocks 52 have fully clamped the circular plate, the reduction motor 13 is activated. The output shaft of the reduction motor 13 drives the gear 14 to rotate. The gear 14 meshes and drives the gear ring 22 to rotate. The gear ring 22 drives the rotating frame 21 to rotate. The rotating frame 21 drives the turntable 23 to rotate. The turntable 23 drives the multiple vertical plates 24 to rotate. The vertical plates 24 drive the multiple ear plates 25 and the multiple cylinders 41 to rotate. The multiple cylinders 41 drive the multiple follower plates 42 to rotate. Multiple rectangular rods 51 rotate, which in turn drive multiple clamping blocks 52 to rotate, thereby achieving the rotation of the clamped circular plate. Multiple rectangular rods 51 drive multiple sliding plates 62 to rotate, which in turn drive multiple upper pressure plates 63 to rotate. Turntable 23 drives multiple cylinders 31 to rotate, which in turn drive the support plate 32 to rotate, thereby driving the circular plate to rotate stably. In conjunction with the rotation of the milling cutter in the milling structure and the feed in the vertical direction, the arc-shaped groove on the circular plate is milled.

[0041] Furthermore, with the circular plate fixed, the rotation of the milling cutter and its vertical feed in the milling structure, combined with the linear motion of the milling cutter, can be used to achieve the grooving process of creating straight grooves on the circular plate.

[0042] In milling structures, the rotation of the milling cutter and its vertical feed, combined with the linear motion of the milling cutter and the rotation of the circular plate around its own axis, can be used to create arc-shaped grooves on the circular plate. At this time, the distance between the different positions of the arc-shaped grooves created by the milling process and the axis of the circular plate is not the same, which is different from the grooving process in milling structures where the milling cutter does not slide linearly on the horizontal plane.

[0043] Each protrusion 53 is attached with a rubber sheet. The rubber sheet increases the friction between the protrusion 53 and the outer edge of the circular plate, thus securing the circular plate more firmly and enabling more precise grooving on the circular plate. The attached rubber sheet is thin and only serves to increase friction; its thickness will not affect the stable clamping of the circular plate by the multiple clamping blocks 52.
