Description

Technical Field

[0001] This invention relates to the field of mold processing technology, specifically to a mold metal component machining device. Background Technology

[0002] When machining through holes such as guide pin holes, guide sleeve holes, and mounting holes in mold components, which serve as assembly positioning references, boring is usually used to ensure the high precision and adaptability of the through holes, and to meet the requirements of mold assembly and use.

[0003] Currently, during boring operations, the workpiece is usually clamped and locked onto the worktable of a vertical boring machine using existing clamping components. The boring bar and boring tool on the machine are driven to rotate synchronously by the spindle. The boring bar and boring tool extend into the through hole to perform the boring operation. However, in order to control the chip flow direction, influence the cutting force direction, and protect the accuracy of the tool tip, it is necessary to adapt to the machining requirements and change the tilt angle of the horizontal boring tool.

[0004] However, once the boring bar is placed horizontally, the following problems will occur in the existing boring machine processing: Due to the horizontal installation requirement of the boring bar and the operation characteristics of the boring bar needing to extend into the through hole for processing, the boring bar has a long cantilever structure during boring operations. The overall rigidity is insufficient, the boring stability is poor, and it is prone to bending and vibration during the processing, affecting the overall processing stability and processing accuracy. Summary of the Invention

[0005] Therefore, it is necessary to provide a machining apparatus for mold metal components, which aims to solve the problems of the prior art mentioned above.

[0006] This application provides a machining apparatus for mold metal components, which works in conjunction with a vertical boring machine, including:

[0007] A worktable, with a spindle mounted above it and a boring bar and boring tool mounted below it.

[0008] The worktable is equipped with a clamping assembly for clamping and locking the workpiece. The clamping assembly includes four circumferentially distributed pressing blocks, and a stabilizing unit is provided between the boring bar and the clamping assembly.

[0009] The stabilization unit includes a concentric inner ring, a concentric inner ring that slides up and down on the boring bar, a concentric outer ring on the worktable, the concentric inner ring and the concentric outer ring are rotatably connected, and the concentric outer ring and the pressing component are locked by a locking component.

[0010] A vertically sliding, oppositely mounted column is provided through the concentric inner ring. The oppositely mounted column is located on the side away from the boring tool cutting point. A transmission component is provided at the lower end of the oppositely mounted column, and a second locking component is provided at the upper end of the oppositely mounted column. After the transmission component is connected to the tail end of the boring tool, the transmission component is locked by the second locking component.

[0011] Using the concentric outer ring locked to the lower pressure block as a support base, a triangular frame is formed by the transfer component, the opposite column, and the boring bar to maintain the tail of the boring tool. The triangular frame is contained in the outer frame of the opposite column, the concentric inner ring, and the concentric outer ring. The entire frame is integrated with the boring tool.

[0012] According to an advantageous embodiment, four circumferentially distributed pads for raising the height of the concentric outer ring are fixedly provided on the lower end face of the concentric outer ring.

[0013] According to an advantageous embodiment, the outer arc-shaped surface of the concentric outer ring is provided with a slide rail, and the side of the concentric inner ring away from the boring tool cutting point is fixedly provided with a slider by a connecting strip, and the slider is slidably disposed in the slide rail.

[0014] The lower sidewall of the slide is inclined upward radially towards the concentric outer ring axis.

[0015] According to an advantageous embodiment, the locking component includes a mating block, with mating blocks fixedly disposed on opposite sides of the left and right pads, and vertically oriented screws fixedly disposed on the upper end face of the mating block and the upper end of the adjacent lower pressing block, with connecting brackets sleeved on the two adjacent screws.

[0016] According to an advantageous embodiment, the transmission assembly includes a connecting block, with the connecting block disposed on the lower end face of the opposite column, and a mating sleeve disposed below the connecting block. Both ends of the mating sleeve are open, and two symmetrically arranged hinge strips are hinged between the mating sleeve and the connecting block.

[0017] The left opening of the mating sleeve is chamfered.

[0018] According to an advantageous embodiment, the transmission assembly further includes a buffer groove, a buffer groove is provided on the right side of the connecting block, the buffer groove extends through the upper end face of the connecting block, an mounting block is fixedly provided on the lower end face of the opposite side column, and a sandwich panel located below the mounting block is placed in the buffer groove, the sandwich panel being made of a high-damping material.

[0019] According to an advantageous embodiment, the second locking component includes a slide block, which is slidably disposed on the right side of the boring bar. The slide block is fixedly disposed on the upper end face of the opposite column. A locking screw with an axis extending from left to right is slidably disposed on the slide block, and a nut is sleeved on the left end of the locking screw.

[0020] According to an advantageous embodiment, when the boring bar is tilted upward from right to left, the connecting block is at its lowest point; when the boring bar is tilted downward from right to left, the connecting block is at its highest point; and when the boring bar is horizontal, the connecting block is in the middle position.

[0021] According to an advantageous embodiment, the left end face of the connecting block is an arc-shaped surface that fits against the circumferential surface of the boring bar, and a reinforcing member located above the concentric inner ring and used to limit the opposite side column is fixedly provided on the boring bar.

[0022] In summary, the present invention has the following beneficial effects: First, the present invention forms a triangular frame that supports the tail end of the boring tool by means of the transmission component, the opposite column, and the boring bar. The triangular frame is formed by the opposite column, the concentric inner ring, and the concentric outer ring within the overall frame. Therefore, while the triangular frame absorbs the vibration transmitted by the boring tool, it prevents the boring tool from forming a cantilever structure. Secondly, the boring bar's own damping properties and the sandwich plate absorb the vibration energy transmitted by the boring tool, forming a double damping effect. The triangular frame and the overall frame, together with the worktable, form an integrated damping system. The system absorbs vibration. In summary, the overall system reduces problems such as vibration and bending caused by insufficient stress during boring tool machining, thereby improving the stability and accuracy during machining.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1 and Figure 3 As shown, a machining device for mold metal components, used in conjunction with a vertical boring machine, includes:

[0034] A worktable 1 is provided above a spindle 10, a boring bar 11 is installed below the spindle 10, and a boring tool 12 is installed below the boring bar 11.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the workbench 1 is provided with a clamping assembly 2 for clamping and locking the workpiece. The clamping assembly 2 includes four circumferentially distributed pressing blocks 20. The pressing blocks 20 are locked and placed to clamp the workpiece by bolts. A stabilizing unit 3 is provided between the boring bar 11 and the clamping assembly 2.

[0036] like Figure 1 and Figure 2 As shown, the stabilization unit 3 includes a concentric inner ring 30, and the concentric inner ring 30 that slides up and down is sleeved on the boring bar 11. A concentric outer ring 31 is provided on the worktable 1. The concentric inner ring 30 and the concentric outer ring 31 are rotatably connected. The concentric outer ring 31 and the pressing component are locked by a locking component 32.

[0037] like Figure 1 and Figure 3As shown, a vertically sliding opposing column 33 with a vertical axis is provided through the concentric inner ring 30. The opposing column 33 is located on the side away from the cutting point of the boring bar 12. A transmission component 34 is provided at the lower end of the opposing column 33, and a locking component 2 35 is provided at the upper end of the opposing column 33. After the transmission component 34 is connected to the tail end of the boring bar 12, the transmission component 34 is locked by the locking component 2 35.

[0038] Using the concentric outer ring 31 locked to the lower pressure block 20 as a support base, a triangular frame is formed by the transmission component 34, the opposite column 33, and the boring bar 11 to maintain the tail end of the boring tool 12. The triangular frame is contained in the outer frame of the opposite column 33, the concentric inner ring 30, and the concentric outer ring 31, forming an integrated frame to connect the boring tool 12.

[0039] First, it should be noted that the worktable 1 is a support component in the vertical boring machine used to support the workpiece, and the spindle 10 is driven to rotate by the spindle 10 box. All of the above components are existing external technologies. Secondly, the way the lower pressure block 20 in the clamping assembly 2 clamps and locks the workpiece is also existing external technology, which will not be elaborated on further.

[0040] During operation, the workpiece is first clamped by the lower pressure block 20 in the clamping assembly 2, causing the worktable 1 to move the workpiece directly below the spindle 10, ensuring that the axis of the through hole to be machined is collinear with the axis of the spindle 10. The positions of the boring bar 12, the transmission assembly 34, and the opposite column 33 are adjusted according to the required tilt angle for machining. The opposite column 33 and the transmission assembly 34 are then locked by the second locking assembly 35. This forms a triangular stable frame at the tail end of the boring bar 12, consisting of the transmission assembly 34, the boring bar 12, and the boring bar 11. Next, the concentric outer ring 31 is manually placed onto the upper surface of the workpiece and locked by the first locking assembly 32. The concentric outer ring 31 is then secured. The clamping assembly 2 forms an integrated frame. It should be noted that the triangular frame is based on the integrated frame, which in turn is based on the concentric inner ring 30, the workpiece, and the worktable 1. Therefore, when the boring tool 12 is boring at different tilt angles, the triangular frame and the integrated frame change the original cantilever machining situation of the boring tool 12, improving the stability of the boring tool 12 during the machining process. Secondly, the force is transmitted to the concentric outer ring 31 and the worktable 1 through the triangular frame and the integrated frame, improving the machining accuracy. Furthermore, the adjustable position of the transmission assembly 34 and the opposite column 33 adapts to the machining requirements of the boring tool 12 at different tilt angles, improving the applicability of the device.

[0041] like Figure 2 and Figure 3 As shown, in order to prevent the concentric outer ring 31 from obstructing the movement of coolant and iron filings, four circumferentially distributed pads 310 are fixedly provided on the lower end face of the concentric outer ring 31 to raise the height of the concentric outer ring 31.

[0042] like Figure 3 and Figure 4 As shown, the outer arc surface of the concentric outer ring 31 is provided with a slide rail 311, and the side of the concentric inner ring 30 away from the cutting point of the boring bar 12 is fixedly provided with a slider 312 by a connecting strip. The slider 312 is slidably disposed in the slide rail 311.

[0043] The lower sidewall of the slide 311 is inclined upward radially toward the axis of the concentric outer ring 31.

[0044] Since coolant is used for cooling and a large amount of iron filings are generated during the machining operation of boring tool 12, the concentric outer ring 31 is raised by pad block 310 during operation to avoid the concentric outer ring 31 from obstructing the discharge of coolant and iron filings. Secondly, the slide rail 311 is positioned away from the boring area, thus reducing the problem of coolant splashing causing some iron filings to enter the slide rail 311 and affect the smooth sliding of slide block 312. This reduces the impact of coolant and iron filings on the stabilization unit 3 to maintain the stable operation of boring tool 12.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the locking component 32 includes a docking block 320. The docking block 320 is fixedly installed on the opposite sides of the two pads 310. The upper end face of the docking block 320 and the upper end of the adjacent pressing block 20 are both fixedly installed with vertically oriented screws. The connecting frame 321 is sleeved on the two adjacent screws. The length of the connecting frame 321 in the left and right directions is adjustable to adapt to locking scenarios of different sizes.

[0046] The connector 321 is locked by tightening the nut onto the screw.

[0047] During operation, after the boring bar 12 and the transmission component 34 are installed, the boring bar 11 is moved to the top of the boring hole. At this time, the concentric outer ring 31 is locked and installed. Specifically, the connecting bracket 321 is manually fitted onto the two corresponding screws, and the connecting bracket 321 is locked by tightening the corresponding nuts on the screws. Thus, the concentric outer ring 31, the connecting bracket 321 and the clamping component 2 are integrated to form an external overall frame, which transmits the stress received from the concentric inner ring 30 and the triangular frame to the worktable 1.

[0048] like Figure 1 , Figure 5 and Figure 6 As shown, the transmission component 34 includes a connecting block 340. The lower end face of the opposite column 33 is provided with the connecting block 340. The connecting sleeve 341 is provided below the connecting block 340. Both the left and right ends of the connecting sleeve 341 are open. Two hinged strips 342 are hinged between the connecting sleeve 341 and the connecting block 340.

[0049] To facilitate fitting the mating sleeve 341 onto the tail of the boring tool 12, the opening of the mating sleeve 341 is chamfered.

[0050] like Figure 1 and Figure 6 As shown, the transmission component 34 also includes a buffer groove. A buffer groove is provided on the right side of the connecting block 340. The buffer groove passes through the upper end face of the connecting block 340. An installation block 344 is fixedly provided on the lower end face of the opposite side column 33. A sandwich plate 345 located below the installation block 344 is placed in the buffer groove. The sandwich plate 345 is made of high damping material.

[0051] The boring bar 11 is a shock-absorbing boring bar 11.

[0052] like Figure 3 , Figure 5 and Figure 6 As shown, the second locking component 35 includes a slide block 350. The slide block 350 is slidably disposed on the right side of the boring bar 11. The slide block 350 is fixedly disposed on the upper end face of the opposite column 33. A locking screw 351 with an axis extending from left to right is slidably disposed on the slide block 350. A nut is sleeved on the left end of the locking screw 351.

[0053] Before machining, the boring bar 11 and boring tool 12 are manually installed onto the spindle 10, and the tilt angle of the boring tool 12 is adjusted according to the set machining conditions. Then, the transfer assembly 34 is installed. The specific operation steps are as follows: The docking sleeve 341 is manually fitted onto the tail of the boring tool 12. During the installation process, the connecting block 340 and the opposite column 33 will move up and down adaptively. At this time, the opposite column 33 drives the slide 350 on it to move up and down synchronously, that is, the slide 350 moves synchronously to the set position. At this point, the nut is manually tightened onto the locking screw 351, locking the slide 350, the opposite column 33, and the connecting block 340 in the above manner. Thus, the mating sleeve 341, the boring tool 12, the hinge strip 342, and the connecting block 340 together form a triangular frame located at the tail of the boring tool 12. This triangular frame prevents the boring tool 12 from being in a cantilever structure. During boring, the stress on the boring tool 12 is transferred to the worktable 1 through the triangular frame and the overall frame, improving the stability of the boring tool 12 during boring.

[0054] It should be further explained that when installing the opposite column 33, the installation block 344 is manually inserted into the buffer groove and the sandwich plate 345 is placed in the buffer groove. Therefore, during the boring operation, the vibration energy transmitted by the boring tool 12 is absorbed by the micro-deformation of the boring bar 11 and the high damping of the sandwich plate 345. The double damping further improves the stability of the triangular frame. The triangular frame and the overall frame work together with the worktable 1 to form an overall damping system, which absorbs vibration.

[0055] When the boring bar 12 is tilted upwards from right to left, the connecting block 340 is at its lowest point; when the boring bar 12 is tilted downwards from right to left, the connecting block 340 is at its highest point. Figure 5 As shown, when the boring bar 12 is horizontal, the connecting block 340 is in the middle position.

[0056] It should be further explained that when the connecting block 340 and the mating sleeve 341 are locked, the distance between the connecting block 340 and the mating sleeve 341 is fixed. Therefore, when the boring tool 12 vibrates and deviates, it will tend to rotate about the mounting center of the boring tool 12. This tendency will also cause the mating sleeve 341 to rotate about the mounting center. The distance between the mating sleeve 341 and the connecting block 340 is fixed. Regarding the connecting block 340, it should be further explained that the stress tendency causes the connecting block 340 to drive the opposite column 33 to move radially along the boring bar 11. By limiting the opposite column 33 with the concentric inner ring 30 and limiting the mating sleeve 341 with the connecting block 340, the mating sleeve 341 and the boring tool 12 are locked, thus counteracting the rotation tendency caused by the vibration.

[0057] Secondly, the adjustable vertical position of the connecting block 340 and the mating sleeve 341 facilitates adaptation to the different tilt angles of the boring bar 12, thus improving the applicability of the device.

[0058] like Figure 6 and Figure 7 As shown, the left end face of the connecting block 340 is an arc-shaped surface that fits against the circumferential surface of the boring bar 11. A reinforcement member 36 is fixedly installed on the boring bar 11 above the concentric inner ring 30 and is used to limit the opposite side column 33.

[0059] By connecting the connecting block 340 to the circumferential surface of the boring bar 11 and by using the reinforcement 36 to limit the opposite side column 33, the axial limitation of the opposite side column 33 is strengthened, thereby improving the ability to counteract the stress transmitted to it by the connecting block 340.

[0060] Additional notes should be added: See Figure 5 and Figure 7 The boring bar 12 of the corresponding length is selected according to the diameter of the boring hole. That is, when the diameter of the boring hole is long, a boring bar 12 of the corresponding longer length needs to be selected. At this time, the mating sleeve 341 can be installed on the side of the boring bar 12 near the boring point. When the diameter of the boring hole is short, the mating sleeve 341 can be installed on the tail end of the boring bar 12. The above technical solutions are all illustrated with the example of the mating sleeve 341 being installed on the tail end of the boring bar 12. The installation position of the mating sleeve 341 is obtained by those skilled in the art through actual operation and is all existing technology. It will not be elaborated in detail.

[0061] This invention adds a concentric inner ring 30, a concentric outer ring 31, a opposite column 33, a transmission component 34, a locking component one 32, and a locking component two 35. The concentric outer ring 31 serves as a supporting base, and the transmission component 34, the opposite column 33, and the boring bar 11 form a triangular frame supporting the opposite side of the boring bar 12's machining side. This triangular frame is located within the outer frame of the opposite column 33, the concentric inner ring 30, and the concentric outer ring 31, forming an integrated frame that connects to the boring bar 12, improving the stability of the boring bar 12 during operation. Simultaneously, the integrated frame transmits force to the concentric outer ring 31 and the worktable, and the double shock absorption further enhances the stability of the triangular frame. The triangular frame and the overall frame, together with the worktable 1, form an integrated damping system that absorbs vibration. In summary, compared with the existing process of directly mounting the boring bar 12 horizontally, this improves the stability and accuracy of the boring bar 12 during operation. Although the above-mentioned components are added in this technical solution, they are all existing conventional mechanical parts that can be used for a long time after a single installation. They can also be used to meet the machining requirements of different boring bar 12 tilt angles. Compared with the economic benefits brought by the improved stability and accuracy, the cost of adding components is negligible. Therefore, this technical solution is a specific improvement made entirely based on and to solve the defects of the existing technology.
