[0002] Currently, in the field of aerospace equipment component repair, the processing of sealing and planar adjustment rubber gaskets mostly adopts a manual cutting method. This involves first making a metal template, and then manually cutting the rubber blank according to the template. Because this manual processing method is greatly affected by human factors, it not only makes it difficult to guarantee the stability of the dimensional accuracy of the rubber parts, but also suffers from low work efficiency.

[0006] The aforementioned high-precision planar rubber part slicing device includes a dimensional adjustment component in the slicing actuator comprising two parts arranged on the left and right sides of the tool holder. Each part is equipped with a tool holder, a fixed sleeve, and a fine-tuning nut, which are fitted onto the outside of the horizontal support rod. The tool holder includes a tool clamping part and a horizontal moving part. The tool holder is assembled with the horizontal support rod through the horizontal moving part, and an external thread is provided at the outer end of the horizontal moving part. The tool clamping part is located below the inner end of the horizontal moving part and is fitted with a slicing tool. The fine-tuning nut is assembled with the external thread at the outer end of the horizontal moving part, and the outer wall of the fine-tuning nut is a stepped cylindrical surface. The fixed sleeve is a stepped sleeve with a stepped annular groove on its large-diameter end inner wall that matches the outer wall of the fine-tuning nut. A fine-tuning nut inlet is provided at the large-diameter end of the fixed sleeve, which radially penetrates the stepped annular groove.

[0007] The aforementioned high-precision planar rubber part slicing device also includes a spring washer in each part of the size adjustment assembly. The spring washer is installed between the fine-tuning nut and the stepped surface of the inner end of the stepped annular groove of the fixing sleeve.

[0008] The aforementioned high-precision planar rubber part slicing device also includes an axially penetrating notch in the horizontal moving part of the cutter holder. After the cutter holder and the horizontal support rod are fitted together, the notch corresponds to the size scale set on the horizontal support rod. Fine-tuning size scale is set circumferentially on the outer wall of the fine-tuning nut.

[0009] The aforementioned high-precision planar rubber part slicing device has a first locking screw hole at the inner end of the horizontal moving part of the cutter holder, and a second locking screw hole at the small diameter end of the fixed sleeve. Locking pins are respectively installed in the first and second locking screw holes, and the locking pins pass through the axially extending grooves on the horizontal support rod.

[0010] The aforementioned high-precision planar rubber part slicing device further includes an upper support, a vertical guide tube, and a screw in the pressing mechanism. The upper support, vertical guide tube, and screw consist of two parts arranged left and right. The upper support is horizontally arranged, with one end assembled to the upper end of the vertical guide tube and the other end extending towards the central axis of the drill bit lifting arm. An arc-shaped groove is provided at its end. The left and right parts of the upper support are clamped around the outside of the drill bit lifting arm of the drill machine through the arc-shaped groove. The upper part of the screw passes through the vertical guide tube, and a pin is provided at the upper end of the screw. The screw is assembled to the vertical guide tube through the pin, and the lower end of the screw is assembled to the pressure plate frame.

[0011] The aforementioned high-precision planar rubber part slicing device further includes a pressure adjustment component in the pressing mechanism, and an elongated hole is opened in the upper part of the vertical guide tube along the vertical direction.

[0014] This invention provides a high-precision planar rubber part dicing device, which, when used in conjunction with a drilling machine, achieves efficient dicing and forming of rubber circular pads. When dicing tools are installed on both the left and right sides of the tool holder simultaneously, the positions of the two sets of dicing tools can be adjusted to ensure that the distance between the cutting edges of the two sets of dicing tools and the central axis of the drilling machine spindle is a set value. When the drilling machine is started, the two dicing tools can dice circular arcs of different diameters to form annular rubber pads. When dicing tools are installed on only one of the left and right sides of the tool holder, the position of the dicing tool can be adjusted to ensure that the distance between its cutting edge and the central axis of the drilling machine spindle is a set value. When the drilling machine is started, the dicing tool can dice circular arcs of a set diameter to form circular rubber pads. This invention incorporates a size adjustment component in the dicing actuator. Coarse adjustment of the dicing tool position can be achieved by adjusting the position of the tool holder and fixing sleeve along the horizontal support rod. Precise adjustment of the dicing tool position can then be achieved by using a fine-tuning nut in conjunction with the tool holder, thereby achieving precise control of the workpiece dimensions. This invention features an axially extending groove on a horizontal support rod. A locking pin inserted into the groove ensures that the cutting edge of the dicing tool remains perpendicular to the dicing table during the adjustment of the tool holder and fixing sleeve, further guaranteeing the dimensional accuracy of the workpiece. After adjustment, the locking pin is tightened to lock the tool holder and fixing sleeve in place. In summary, this invention, through these measures, ensures the dimensional accuracy of rubber parts, thereby improving product quality and work efficiency. Attached Figure Description

The tail of the locking pin 1-6 is inserted into the slide groove 1-1-3 extending axially on the horizontal support rod 1-1-2. When the tool holder 1-2 is adjusted to the left or right position along the horizontal support rod 1-1-2 of the tool holder 1-1, the locking pin 1-6 is loosened. At this time, the locking pin 1-6 and the slide groove 1-1-3 can cooperate to provide a horizontal guiding effect for the tool holder 1-2, ensuring that the cutting edge of the dicing tool 1-7 is always perpendicular to the table surface of the dicing worktable 3.

[0022] See Figure 2 , Figure 5 , Figure 7 , Figure 8The high-precision planar rubber part slicing device of this utility model has a fine-tuning nut 1-3 in the size adjustment component of the slicing actuator 1, which is used to precisely adjust the position of the cutter holder 1-2. The fine-tuning nut 1-3 is fitted with the external thread 1-2-2-1 on the outer side of the horizontal moving part 1-2-2 of the cutter holder 1-2. The outer side wall of the fine-tuning nut 1-3 is a stepped cylindrical surface. The fixing sleeve 1-5 of the size adjustment component is a stepped sleeve. The inner wall of its large-diameter end is provided with a stepped annular groove 1-5-1 that matches the outer side wall of the fine-tuning nut 1-3. A fine-tuning nut inlet 1-5-2 is provided at the radial end of a stepped annular groove 1-5-1. During the assembly of the size adjustment assembly, the fine-tuning nut 1-3 can pass through the fine-tuning nut inlet 1-5-2 and enter the stepped annular groove 1-5-1 of the fixing sleeve 1-5, and then be assembled with the horizontal support rod 1-1-2. The fixing sleeve 1-5 is assembled with the horizontal support rod 1-1-2 through its small-diameter end in a clearance fit manner. A second locking screw hole 1-5-3 is provided at the small-diameter end of the fixing sleeve 1-5. The second locking screw hole 1-5-3 is a radial threaded hole.

The spring washer 1-4 flexibly applies pressure to the fine-adjusting nut 1-2, which not only facilitates the control of the screwing angle of the fine-adjusting nut 1-2, but also prevents the fine-adjusting nut 1-2 from becoming loose and affecting the slicing accuracy when the locking pin 1-6 installed in the first locking screw hole 1-2-2-3 of the cutter holder 1-2 fails during the operation of the slicing execution mechanism 1.

[0024] See also Figure 2 , Figure 5 , Figure 7 , Figure 8 The high-precision planar rubber part slicing device of this utility model has an axially penetrating notch 1-2-2-2 on the horizontal moving part 1-2-2 of the cutter holder 1-2.

The compression spring 2-5 is installed between the upper end face of the bushing 2-6 and the stepped surface of the stepped hole of the vertical guide tube 2-2.

[0027] See Figures 1 to 12 The working process of this utility model is as follows: When performing planar rubber part slicing operations using this utility model, the rubber blank is placed on the table surface of the slicing workbench 3. Depending on the shape of the workpiece, the slicing cutter 1-7 is installed on both the left and right sides of the cutter holder 1-1 simultaneously, or only on the left or right side of the cutter holder. A pressure plate 2-9 matching the size of the workpiece is selected. When the workpiece being scribed is a circular rubber washer, scribers 1-7 are installed simultaneously on both the left and right sides of the tool holder 1-1. By adjusting the positions of the two sets of scribers 1-7, the distances between the cutting edges of the two sets of scribers 1-7 and the central axis of the spindle of the drilling machine 4 are set values ​​L1 and L2, respectively. At this time, the drilling machine 4 is started, and the material clamping mechanism 2 moves downward with the lifting arm of the drilling machine 4. The rubber blank on the table of the scriber worktable 3 is pressed and fixed by the pressure plate 2-9. Then, the two scribers 1-7 are used to scribe circular arcs of different diameters to form a circular rubber washer with a width of L1-L2. When the workpiece being scribed is a circular rubber pad, only the scribers 1-7 need to be installed on the left or right side of the tool holder 1-1. By adjusting the positions of the scribers 1-7, the distance between the cutting edges of the scribers 1-7 and the central axis of the spindle of the drilling machine 4 is set. At this time, the drilling machine 4 is started, and the scribers can scribe circular arcs of a set diameter to form a circular rubber pad.

[0028] When adjusting the position of the dicing blade 1-7, the specific operating steps are as follows: First, make a rough adjustment to the left and right position of the blade holder 1-2. Loosen the locking pins 1-6 on the blade holder 1-2 and the fixing sleeve 1-5. The blade holder 1-2 and the fine-tuning nut 1-2 mounted on the blade holder 1-2 will move the fixing sleeve 1-5 left and right on the horizontal support rod 1-1-2. At this time, the locking pins 1-6 and the sliding groove 1-1-3 can cooperate to provide horizontal guidance for the blade holder 1-2 and the fixing sleeve 1-5. After the rough adjustment of the position of the blade holder 1-2 is completed, tighten the fixing sleeve 1-7. 5. Lock the fixing sleeve 1-5 with the locking pin 1-6. Then, make a precise adjustment to the position of the tool holder 1-2. At this time, the locking pin 1-6 of the tool holder 1-2 is still loose. Tighten the fine-tuning nut 1-3. The fine-tuning nut 1-3 and the tool holder 1-2 form a screw-nut transmission pair. The fine-tuning nut 1-3 only rotates under the restraint of the fixing sleeve 1-5. The tool holder 1-2 moves slightly left and right, thereby achieving a precise adjustment to the position of the tool holder 1-2. After the precise adjustment of the position of the tool holder 1-2 is completed, tighten the locking pin 1-6 to lock and fix the tool holder 1-2.

[0029] This utility model can adjust the clamping force of the pressing mechanism 2 according to the thickness of the workpiece being cut. The specific operation steps are as follows: turn the pressure adjusting nut 2-7 to move the bushing 2-6 up and down, and use the compression spring 2-5 to flexibly push the vertical guide tube 2-2 up and down to the set position.

[0030] During the operation of the pressing mechanism of this utility model, the lifting arm of the drilling machine 4 moves downward, pushing the upper support 2-1, vertical guide tube 2-2, pressing frame 2-8 and pressing plate 2-9 in the pressing mechanism 2 to move downward synchronously. When the pressing plate 2-9 comes into contact with the rubber blank on the table surface of the dicing worktable 3, part of the clamping force can be absorbed by the deformation of the compression spring 2-5, so that the clamping force transmitted to the rubber blank by the pressing frame 2-8 and the pressing plate 2-9 is within the set range.
