Description

Technical Field

[0001] This utility model belongs to the field of wear-resistant sheet milling technology, and specifically relates to a wear-resistant sheet milling fixture. Background Technology

[0002] Wear-resistant plates are functional components with high hardness, high toughness, and excellent wear resistance. In actual production, in order to meet the needs of different working conditions, wear-resistant plates often need to undergo processing steps such as center punching or circumferential edge grinding. The above processing is usually achieved with the help of milling equipment. The milling fixture plays a key role in positioning the wear-resistant plate during the milling equipment processing. It can accurately position and reliably clamp the wear-resistant plate to ensure processing accuracy and thus ensure the pass rate of the milled wear-resistant plate finished product.

[0003] A related technology (Chinese utility model patent with publication number CN217343753U) discloses a fixture for batch milling of wear-resistant plates, comprising: a tooling base; a fixing plate installed below the tooling base, the fixing plate having multiple central grooves equidistantly rectangularly spaced; and multiple pressure blocks installed on the top of the tooling base, each pressure block having a second threaded hole, the pressure blocks being connected to the tooling base via the second threaded holes and bolts. This fixture for batch milling of wear-resistant plates eliminates the need for re-alignment and resetting of the machining origin after each workpiece is clamped during processing, avoiding workpiece scrap due to forgetting to set the machining origin. It also eliminates the need to stop the machine for product clamping, improving production efficiency and yield. Furthermore, it allows adjustment of the clamping thickness to accommodate different types of wear-resistant plates. When it is necessary to fix the pressure blocks 300, the wear-resistant plate is placed on the central groove 210 between two pressure blocks 300, and the pressure blocks 300 on both sides fix the wear-resistant plate, thus functioning as a clamp.

[0004] In the above processing scheme, a horizontally arranged positioning fixture is used to fix the wear-resistant sheet. This fixture only forms a single-point contact clamp with the bottom end of the wear-resistant sheet. In this single-point positioning method, due to the lack of multi-directional constraints during the center punching process, the wear-resistant sheet is very prone to displacement due to external forces such as cutting force and vibration. This positioning instability will directly lead to quality defects such as deviation in the hole diameter position accuracy and excessive hole wall roughness, thereby reducing the processing accuracy and pass rate of the entire batch of products. Utility Model Content

[0005] To address the problem that existing technologies rely on a single-point clamping method where the fixture only contacts the bottom of the wear-resistant sheet, which is prone to displacement under external forces, leading to quality defects such as deviations in the hole diameter accuracy and excessive hole wall roughness, and consequently reducing the overall machining accuracy and yield of the batch, this invention provides a milling fixture for wear-resistant sheets. This fixture employs a dual-point clamping structure, significantly enhancing the anti-disturbance properties during milling, suppressing displacement deformation, ensuring machining accuracy, improving the yield of finished products, and achieving stable and consistent quality in batch processing. The specific technical solution is as follows:

[0006] A milling fixture for wear-resistant plates is provided for clamping and positioning wear-resistant plates. It includes two sets of clamping units arranged symmetrically from left to right. Each clamping unit includes: a vertical plate, a through slot, a guide rod, a first plate, a second plate, a connecting piece, a side plate, and a hydraulic cylinder. The vertical plate is arranged vertically. The through slot extends from left to right through the vertical plate. The guide rod is fixedly installed vertically within the through slot. Multiple first plates are provided, equidistantly and fixedly installed vertically on the side wall of the vertical plate. Multiple second plates are provided, equidistantly arranged vertically. The second plates are movable and lifted, sleeved on the guide rod, and positioned above the first plates. The connecting piece is fixedly installed on the side wall of the second plate. The side plate is vertically and fixedly installed on the side wall of the connecting piece. The hydraulic cylinder is installed on the side wall of the vertical plate, and its output end is fixedly connected to the connecting piece at the top.

[0007] The wear-resistant sheet is positioned between the first plate and the second plate.

[0008] In the above technical solution, the number of the first plate and the second plate are the same.

[0009] In the above technical solution, a first flexible pad is installed on the upper surface of the first plate, and a second flexible pad is installed on the lower surface of the second plate.

[0010] In the above technical solution, the relative positions of the two clamping units are adjusted by an adjustment unit. The adjustment unit includes a first support arm, a rotating shaft, and a second support arm. The first support arm is fixedly installed at the bottom end of the right clamping unit, and an opening is provided on the left side of the first support arm. The rotating shaft is rotatably connected to the opening on the left side of the first support arm. The second support arm is fixedly installed at the bottom end of the left clamping unit, and the second support arm is fixedly connected to the rotating shaft.

[0011] In the above technical solution, the adjustment unit further includes: a positioning block, a positioning hole, and a positioning rod. The positioning block is fixedly installed on the rotating shaft. Multiple positioning holes are provided, and all of the multiple positioning holes are opened vertically through the first support arm. The multiple positioning holes are equidistantly arranged circumferentially with the vertical central axis of the rotating shaft as the axis. The positioning rod passes through one of the positioning holes vertically and then passes downward through the positioning block.

[0012] In the above technical solution, a handle is installed on the side wall of the positioning block.

[0013] In the above technical solution, the left and right clamping units are arranged symmetrically about the vertical central axis of the rotating shaft.

[0014] The above technical solution also includes two sets of connecting components, which are symmetrically arranged on the front and rear side walls of the first support arm. Each set of connecting components includes: a mounting base, a positioning bolt, a slider, and a positioning nut. The mounting base is fixedly installed on the side wall of the first support arm; the positioning bolt slides vertically through the mounting base, and the top of the positioning bolt is provided with an external thread; the slider is fixedly installed on the bottom end of the positioning bolt; and the positioning nut is threaded onto the top end of the positioning bolt.

[0015] The above technical solution also includes: a worktable and a T-slot, wherein the worktable is arranged in a horizontal direction; multiple T-slots are provided, and the multiple T-slots are respectively opened in a horizontal direction on the upper surface of the worktable, and the cross-sectional shape of the T-slot is T-shaped.

[0016] In the above technical solution, the slider is slidably embedded in the inner cavity of the T-slot.

[0017] The wear-resistant sheet milling fixture of this utility model has the following advantages compared with the prior art:

[0018] I. In view of the existing positioning method where the fixture only forms a single-point contact with the bottom end of the wear-resistant sheet, it is easy for displacement to occur under the action of external force, resulting in quality defects such as deviation of the hole diameter position accuracy and excessive hole wall roughness, which in turn reduces the processing accuracy and pass rate of the entire batch of products. This utility model adopts a dual-point clamping positioning structure. Compared with the traditional horizontal single-point positioning method, it significantly improves the anti-disturbance ability of the wear-resistant sheet during the milling process, effectively suppresses displacement deformation under the action of external force, ensures the accuracy of the drilling, milling and other processing steps of the wear-resistant sheet, greatly improves the pass rate of finished products, and realizes the quality stability and product consistency control in the batch processing of wear-resistant sheets.

[0019] II. This utility model adopts a layered structure layout, integrating multiple sets of first and second plate positioning components. Under the action of a single driving force, each second plate component can move synchronously, quickly and accurately clamping and fixing the wear-resistant sheet at the corresponding position between the first and second plates. This achieves parallel positioning and clamping of multiple wear-resistant sheets at one time, significantly improving clamping efficiency. Compared with the traditional method of positioning one by one, this solution can shorten auxiliary time and better meet the high-efficiency positioning requirements for uniform milling of wear-resistant sheets in industrial mass production.

[0020] Third, this utility model can not only clamp and position the wear-resistant sheet at two points, but also adjust the relative position of the two points. By dynamically adjusting the relative position of the two positioning points, while ensuring the stable clamping of the wear-resistant sheet, the exposed range of its circumferential edge can be flexibly expanded, effectively optimizing the milling operation space, significantly improving the accessibility and processing convenience of the milling tool to the circumferential edge of the wear-resistant sheet, and meeting the complex processing needs under different working conditions.

[0021] IV. In this utility model, the position adjustment of the second support arm relative to the first support arm can be achieved through the cooperation of components such as the rotating shaft, positioning block, positioning hole, and positioning rod. After the adjustment is completed, the second support arm is ensured to be stably maintained in the target position. This effectively ensures that the fixture can still provide stable and reliable clamping and positioning for the wear-resistant sheet after the position adjustment, meeting the process requirements of high precision and high stability clamping of workpieces under complex working conditions, and improving the reliability and consistency of the fixture in the processing process.

[0022] In summary, this utility model adopts a dual-point clamping and positioning structure, which not only significantly enhances the anti-disturbance properties during the milling of wear-resistant sheets, suppresses displacement deformation, ensures machining accuracy, improves the finished product qualification rate, and achieves stable and consistent quality in batch processing, but also dynamically adjusts the relative positions of the two positioning points. While firmly clamping the wear-resistant sheets, it expands the exposed range of the circumferential edge of the wear-resistant sheets, optimizes the machining space, improves milling convenience, and meets the needs of diverse working conditions.

[0032] The following are specific implementation cases and appendices. Figures 1 to 8 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0033] Example 1

[0034] See Figures 1 to 6As shown, a milling fixture for wear-resistant plates is used for clamping and positioning wear-resistant plates 24. It includes two sets of clamping units arranged symmetrically to the left and right to clamp and position the wear-resistant plates 24 at two points. Each clamping unit includes: a vertical plate 1, a through groove 2, a guide rod 3, a first plate 4, a second plate 5, a connecting piece 6, a side plate 7, and a hydraulic cylinder 8. The vertical plate 1 is arranged vertically. The through groove 2 extends from left to right through the vertical plate 1. The guide rod 3 is fixedly installed vertically within the cavity of the through groove 2. Multiple first plates 4 are provided, and these plates are equidistantly and fixedly installed vertically on the side wall of the vertical plate 1. Multiple second plates 5 are provided, and these plates are equidistantly arranged vertically. The second plates 5 are movably mounted on the guide rod 3. The guide rod 3 guides the lifting and lowering movement of the second plate 5 relative to the first plate 4, ensuring that the second plate 5 is always parallel to the first plate 4 and positioned above the first plate 4. The wear-resistant plate 24 is positioned between the first plate 4 and the second plate 5. The second plate 5 moves downwards, positioning the wear-resistant plate 24 above the first plate 4. The connecting plate 6 is fixedly installed on the side wall of the second plate 5. The side plate 7 is vertically and fixedly installed on the side wall of the connecting plate 6. The hydraulic cylinder 8 is installed on the side wall of the upright plate 1, and its output end is fixedly connected to the connecting plate 6 at the top. Specifically, the number of first plates 4 and second plates 5 is the same, ensuring that each first plate 4 and each second plate 5 corresponds in position, forming a clamping and positioning of the corresponding number of wear-resistant plates 24.

[0035] When the hydraulic cylinder 8 is started, its output end drives the top connecting piece 6 to move downward. The side plate 7 then drives all the connecting pieces 6 to move downward synchronously. The second plate 5 connected to the connecting piece 6 is also driven downward by this force until the second flexible pad 10 on the lower surface of the second plate 5 is tightly attached to the upper surface of the wear-resistant piece 24. This achieves one-time clamping and positioning of all the wear-resistant pieces 24 between the corresponding first plate 4 and second plate 5. Each group of wear-resistant pieces 24 adopts dual-point clamping. In the subsequent top-down punching process, this positioning method can effectively maintain the stability of the wear-resistant pieces 24 and significantly improve the product processing qualification rate.

[0036] This utility model innovatively utilizes a dual-point clamping and positioning structure to fundamentally improve the anti-interference performance of wear-resistant sheets in milling machining scenarios. Through precise dual-point clamping, it effectively resists displacement deformation caused by external forces such as cutting forces and vibrations, ensuring that drilling, milling and other processes strictly meet tolerance standards. In mass production, this structure can ensure a high degree of uniformity in the processing quality of each wear-resistant sheet, significantly reducing the defect rate and providing a reliable clamping solution for precision manufacturing.

[0037] In addition, a first flexible pad 9 is installed on the upper surface of the first plate 4, and a second flexible pad 10 is installed on the lower surface of the second plate 5. Both the first flexible pad 9 and the second flexible pad 10 are commonly used flexible pads on the market. In this embodiment, both the first flexible pad 9 and the second flexible pad 10 are made of rubber, which can protect the surface of the wear-resistant sheet 24 clamped between the first plate 4 and the second plate 5, and prevent the wear-resistant sheet 24 from being damaged due to excessive clamping force. Moreover, the rubber material of the first flexible pad 9 and the second flexible pad 10 can increase the friction with the surface of the wear-resistant sheet 24. Compared with the positioning method where the first plate 4 and the second plate 5 directly contact the wear-resistant sheet 24, it can better ensure the stability of the wear-resistant sheet 24 during positioning.

[0038] Main references Figures 2 to 5 As shown, the relative positions of the two clamping units are adjusted by an adjustment unit, which includes a first support arm 11, a rotating shaft 12, and a second support arm 13. The first support arm 11 is fixedly installed at the bottom of the right clamping unit. Specifically, the first support arm 11 is fixedly installed at the bottom of the right vertical plate 1, and an opening is provided on the left side of the first support arm 11. The rotating shaft 12 is rotatably connected to the opening on the left side of the first support arm 11 through a bearing. The second support arm 13 is fixedly installed at the bottom of the left clamping unit. Specifically, the second support arm 13 is fixedly installed at the bottom of the left vertical plate 1, and the second support arm 13 is fixedly connected to the rotating shaft 12. When the second support arm 13 rotates relative to the first support arm 11, it causes the left vertical plate 1 to rotate relative to the right vertical plate 1 about the rotating shaft 12 as an axis, so as to realize the adjustment of the relative positions of the two clamping units on the left and right sides, thereby meeting the processing requirement of exposing more area of ​​the circumferential edge of the wear-resistant sheet 24.

[0039] Main references Figure 3 and Figure 5 As shown, the adjustment unit also includes: a positioning block 14, a positioning hole 16, and a positioning rod 17. The positioning block 14 is fixedly installed on the rotating shaft 12. Multiple positioning holes 16 are provided, and all multiple positioning holes 16 are opened vertically through the first support arm 11. The multiple positioning holes 16 are equidistantly arranged circumferentially with the vertical central axis of the rotating shaft 12 as the axis. The positioning rod 17 passes through one of the positioning holes 16 vertically and then passes downward through the positioning block 14.

[0040] When the positioning rod 17 is pulled upwards to disengage it from the inner cavity of the corresponding positioning hole 16, and the bottom end of the positioning rod 17 is separated from the outer wall of the positioning block 14, the locking limit state between the second support arm 13 and the first support arm 11 is released. At this time, when the second support arm 13 is rotated, the clamp at its top end will rotate synchronously, thereby realizing the relative position adjustment between the left clamp and the right clamp. During the rotation of the second support arm 13, the rotating shaft 12 will drive the positioning block 14 to rotate together. After the position adjustment is completed, the positioning rod 17 is passed through the inner cavity of the positioning hole 16 from top to bottom, and the bottom end of the positioning rod 17 is passed through the outer wall of the positioning block 14 again, thereby re-locking the relative position between the positioning block 14 and the first support arm 11 after rotation.

[0041] Therefore, this utility model can dynamically adjust the relative positions of the two positioning points, which can stabilize the wear-resistant sheet while expanding the exposed range of the circumferential edge of the wear-resistant sheet, optimizing the processing space, improving the convenience of milling, and meeting the needs of diverse working conditions.

[0042] In addition, to facilitate the rotation of the positioning block 14, a handle 15 is installed on the side wall of the positioning block 14. By holding the handle 15, it is easier to drive the positioning block 14 to rotate and adjust around the axis 12. The left and right clamping units are symmetrically arranged around the vertical central axis of the axis 12. This ensures that after the relative positions of the left and right clamping units are adjusted, the two positioning points on the wear-resistant plate 24 are still evenly distributed, so that the two clamping units can still achieve stable dual-point positioning of the wear-resistant plate 24 after adjusting the relative positions.

[0043] In addition, the main references Figure 4 , Figures 6 to 8 As shown, this solution also includes two sets of connecting components, which are symmetrically arranged on the front and rear side walls of the first support arm 11. Each set of connecting components includes: a mounting base 20, a positioning bolt 22, a slider 21, and a positioning nut 23. The mounting base 20 is fixedly installed on the side wall of the first support arm 11; the positioning bolt 22 slides vertically through the mounting base 20, and the top of the positioning bolt 22 is provided with an external thread; the slider 21 is fixedly installed on the bottom end of the positioning bolt 22; and the positioning nut 23 is threaded onto the positioning bolt 22. Top; This solution also includes: a worktable 18 and a T-slot 19. The worktable 18 is arranged horizontally; multiple T-slots 19 are provided, and the multiple T-slots 19 are respectively opened horizontally on the upper surface of the worktable 18, and the cross-sectional shape of the T-slot 19 is T-shaped; the slider 21 is slidably embedded in the inner cavity of the T-slot 19. By sliding the slider 21 into the inner cavity of the T-slot 19, the first support arm 11 can be initially connected on the worktable 18. In this state, the first support arm 11 is limited in the front-back direction;

[0044] Specifically, when assembling the fixture on the worktable 18, it is only necessary to form a connection between the first support arm 11 and the worktable 18: slide the slider 21 into the appropriate position along the inner cavity of the T-slot 19 at the corresponding position, put the mounting seat 20 on the top of the positioning bolt 22, and make the bottom end of the mounting seat 20 fit against the upper surface of the worktable 18. Rotate the positioning nut 23 to make it gradually descend along the thread at the top of the positioning bolt 22 until the lower surface of the positioning nut 23 is tightly fitted against the upper surface of the mounting seat 20. In this way, the positioning nut 23 positions the mounting seat 20 on the worktable 18, that is, the first support arm 11 and the worktable 18 are locked together.

[0045] It is worth noting that the hydraulic cylinder 8 used in this application is a commonly used self-locking cylinder on the market. Its output end can stop at any position and lock. It adopts a common model on the market, which can meet the usage requirements of this application. It will not be described or limited here. The worktable 18 is a worktable of a commonly used milling equipment on the market. It is used to help understand the positional connection relationship between the fixture of this application and the worktable of the existing milling equipment. That is, this solution does not improve the milling equipment. Therefore, the milling equipment can be a common equipment on the market. It will not be limited or described here.

[0046] The working principle of the wear-resistant sheet milling fixture in this embodiment is as follows:

[0047] After placing multiple sets of wear-resistant plates 24 at the first flexible pads 9 on the first plate 4 at corresponding positions, align the positions of the upper and lower wear-resistant plates 24 to ensure that the centers of all wear-resistant plates 24 are located on the same vertical axis. Drive the connecting piece 6 at the top to move downward by the output end of the activated hydraulic cylinder 8, so that the side plate 7 drives all connecting pieces 6 to move downward synchronously. At this time, the second plate 5 connected to the connecting piece 6 is forced to move downward until the second flexible pad 10 on the lower surface of the second plate 5 clamps and adheres to the upper surface of the wear-resistant plate 24. At this time, all wear-resistant plates 24 can be clamped and positioned at the first plate 4 and the second plate 5 at the corresponding positions in one go. In this state, each set of wear-resistant plates 24 can be clamped and positioned at two points, which can effectively ensure the stability of the wear-resistant plates 24 and the qualified rate of the processed products when punching the wear-resistant plates 24 from top to bottom in the subsequent process.

[0048] This utility model adopts a dual-point clamping and positioning structure, which can significantly enhance the anti-disturbance properties during wear-resistant sheet milling, suppress displacement deformation, ensure machining accuracy, improve the finished product qualification rate, and achieve stable and consistent quality in batch processing.

[0049] Example 2

[0050] See Figure 7 and Figure 8The diagram shown illustrates the relative position adjustment of the left and right clamping units. If more area of ​​the circumferential edge of the wear-resistant plate 24 needs to be exposed to facilitate subsequent milling operations on the circumferential edge of the wear-resistant plate 24, the positioning rod 17 is pulled upward out of the corresponding positioning hole 16 cavity, and the bottom end of the positioning rod 17 is disengaged from the outer wall of the positioning block 14. At this time, the second support arm 13 and the first support arm 11 are no longer locked and limited. The second support arm 13 is rotated to make the clamp at its top rotate synchronously, which can realize the relative position adjustment of the left clamp relative to the right clamp. During the rotation of the second support arm 13, the rotating shaft 12 drives the positioning block 14 to rotate synchronously. After the position is adjusted, the positioning rod 17 is re-penetrated from top to bottom through the corresponding positioning hole 16 cavity, and the bottom end of the positioning rod 17 is re-penetrated downward through the outer wall of the positioning block 14. This locks the relative position of the rotating positioning block 14 and the first support arm 11, that is, locks the position between the second support arm 13 and the first support arm 11 after the relative position adjustment. At this time, the positions of the two sets of clamps are stably limited.

[0051] Referring to the positioning steps for multiple sets of wear-resistant plates 24 in Embodiment 1 above, multiple sets of wear-resistant plates 24 can be simultaneously positioned between the first plate 4 and the second plate 5 so that the circumferential edges of the wear-resistant plates 24 exposed to the outside can be milled.

[0052] Therefore, this utility model can also dynamically adjust the relative position of the two positioning points, which can expand the exposed range of the circumferential edge of the wear-resistant sheet while firmly clamping it, optimize the processing space, improve the convenience of milling, and meet the needs of diverse working conditions.
