Description

Technical Field

[0001] This invention relates to the field of CNC machine tool design and manufacturing, and in particular to a photocopying auxiliary device and method. Background Technology

[0002] The heat that affects machine tool temperature can be divided into internal heat and external heat. Internal heat mainly comes from the heat generated by the machine tool itself, such as the heat generated by the spindle motor during long-term operation. External heat mainly comes from the heat generated by heat transfer or radiation from the outside to the machine tool, such as the cutting heat generated by cutting the workpiece. Although the cutting fluid will carry away most of the cutting heat, this heat does not disappear. Some of the heat carried by the cutting fluid will still be transferred to the machine tool. In addition to cutting heat, ambient temperature will also affect the temperature of the machine tool.

[0003] As a crucial component of the machine tool's feed system, the guide rail consists of a saddle and a slider fixed together with the guide rail by screws. The saddle primarily bears the weight of the ram and its associated components, as well as cutting forces. Its main functions are load-bearing, positioning, and connection. As a component that mates with the guide rail, the saddle significantly impacts the machining accuracy of the machine tool machining center and the quality of the workpiece. Saddles and rams made of gray cast iron are susceptible to both internal and external heat, leading to overheating. Overheating causes the temperature of the saddle and ram to rise, resulting in deformation due to thermal expansion. For example, changes in the relative position of the spindle's rotation centerline within the ram and other machine tool components can cause the ram to lose its existing geometric accuracy, thereby affecting the machining quality of the workpiece.

[0004] Currently, manual scraping and running-in methods are commonly used to process the first guide rail mounting surface that contacts the slide saddle and the ram guide rail, and the second guide rail mounting surface that contacts the slide saddle and the column guide rail. The purpose of manual scraping and running-in is to reduce the surface roughness value so that the geometric accuracy requirements of the guide rail mounting surface that mates with the machine tool components are similar to the geometric accuracy of the slide saddle reference surface.

[0005] The slide saddle is equipped with a guide rail connecting groove and a support surface. The support surface is used to connect with the steel-insulated guide rail pressure plate, making the steel-insulated guide rail pressure plate parallel to the bottom wall of the guide rail connecting groove. At this time, the bottom wall of the guide rail connecting groove and the steel-insulated guide rail pressure plate form a guide rail installation space that mates with the guide rail. Currently, the support surface is first machined into a precision surface using manual scraping and grinding methods. Then, the steel-insulated guide rail pressure plate and the bottom wall of the guide rail connecting groove are machined into precision surfaces to ensure that the geometric accuracy requirements of the guide rail installation surface that mates with the slide saddle and machine tool components meet the slide saddle reference. While the surface geometric accuracy is similar, due to the special structure of the slide saddle and the limited machining space of the slide ram connecting groove, the edges and corners of the mounting surface are easily overlooked by the human eye during manual scraping and running-in, resulting in uneven roughness of the mating surfaces after machining. This makes it difficult to guarantee the accuracy of the bottom wall and support surface of the guide rail connecting groove, as well as the accuracy of the first and second guide rail mounting surfaces, thus affecting the motion and geometric accuracy of the mating surfaces between the slide saddle and the slide ram, and consequently the overall accuracy of the machine tool. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention discloses a copying processing auxiliary device and a copying method, which uses a processed precision surface as a reference surface to copy the first guide rail mounting surface and the second guide rail mounting surface, ensuring that the processed guide rail surface and the precision surface are matched, ensuring that the roughness of the copying surface and the precision surface are equal, and ensuring the motion accuracy and geometric accuracy between the slide saddle and the slide block.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] A photocopying auxiliary device includes a mold base, a first template and a second template, and an adjustment device. The adjustment device is used to adjust the installation position of the workpiece on the mold base. The upper surface of the mold base is machined into a precision surface. The first template and the second template are both fixed on the precision surface and are perpendicular to each other. There are two first templates, which are parallel and spaced apart. The second template is disposed at the end of the first template and is located on the same side of the two first templates. The geometric precision of the surface of the first template, the surface of the second template, and the first precision surface are equal.

[0009] Furthermore, the adjustment device is in multiple sets, and the multiple sets of adjustment devices are evenly distributed along the circumferential direction of the mold base.

[0010] Furthermore, the adjusting device includes an adjusting block and a bolt, wherein the adjusting block can be tightened against the slide saddle by the bolt.

[0011] Furthermore, the mold base is provided with an adjustment component capable of adjusting the distance between the adjustment block and the mold base.

[0012] Furthermore, the adjusting assembly includes a vertically arranged screw and nut, the adjusting block is provided with a through hole for the screw to pass through, each screw is provided with two nuts, the two nuts are respectively provided on the upper and lower sides of the adjusting block, and the contact surface between the nut and the adjusting block is set as an arc-shaped end.

[0013] The method of using the copying slide saddle of the aforementioned copying processing auxiliary device includes the following steps:

[0014] The slide saddle includes the bottom surface of the guide rail connecting groove to be processed and the reference surface to be processed. The bottom surface of the guide rail connecting groove is ground to obtain the ground surface.

[0015] The slide saddle with the polished surface is hoisted above the copy processing auxiliary device. The position of the slide saddle and the copy processing auxiliary device is adjusted by manual coarse calibration. Guide rail adhesive is applied to the surface of the first template and the surface of the second template in sequence.

[0016] The slide saddle is lowered onto the copy processing auxiliary device so that the reference surface of the slide saddle contacts the precision surface of the copy processing auxiliary device. Gaps are formed between the plate surface of the first template and the plate surface of the second template and the corresponding grinding surface, respectively. The guide rail adhesive fills the gaps. The slide saddle is kept stationary in its original position until the guide rail adhesive is fully cured to obtain the copy surface.

[0017] The method for using a copying insert with the aforementioned copying processing auxiliary device includes the following steps:

[0018] A mounting block with a reference surface is fabricated. The mounting block is machined with an inclined bevel and a flat surface. The inclination angle of the inclined bevel is opposite to that of the inlay. The flat surface is ground to become the reference surface, and the accuracy of the reference surface is equal to that of the precision surface. The inlay is installed onto the inclined surface of the mounting block. After installation, the surface of the inlay is nearly flush with the reference surface of the mounting block. The surface of the inlay is then ground to obtain a polished surface.

[0019] The polished strip is hoisted above the copy processing auxiliary device. The position of the strip is adjusted to correspond with the position of the copy processing auxiliary device by manual coarse calibration. Guide rail adhesive is then applied to the precision surface in sequence.

[0020] The insert is lowered onto the copy processing auxiliary device so that the reference surface of the insert contacts the precision surface of the copy processing auxiliary device. At this time, a gap is formed between the precision surface and the corresponding grinding surface. The guide rail adhesive fills the gap and keeps the insert stationary in its original position until the guide rail adhesive is fully cured to obtain the copy surface.

[0021] The method for using the photocopying auxiliary device with the photocopying inlay guide plate includes the following steps:

[0022] The steel-insulated guide rail pressure plate includes a fixing part and a guide rail mating part. The guide rail mating part is ground to obtain a ground surface, and the fixing part is machined to obtain a reference surface with the same geometric accuracy as the precision surface.

[0023] The steel-inlaid guide plate with the polished surface is hoisted above the copy processing auxiliary device. The position of the steel-inlaid guide plate is adjusted to correspond with the position of the copy processing auxiliary device by manual coarse calibration. Guide rail adhesive is then applied to the precision surface in sequence.

[0024] The steel-inlaid guide plate is lowered onto the copy processing auxiliary device so that the reference surface of the steel-inlaid guide plate contacts the precision surface of the copy processing auxiliary device. At this time, a gap is formed between the precision surface and the corresponding grinding surface. The guide plate adhesive fills the gap. The steel-inlaid guide plate is kept stationary in its original position until the guide plate adhesive is fully cured to obtain the copy surface.

[0025] Furthermore, when applying the guide rail adhesive, the thickness of the adhesive gradually decreases from the center to the edge of the plate surface.

[0026] Furthermore, before lowering the workpiece to be processed into the photocopying auxiliary device, the position of the workpiece is first finely adjusted using an adjustment device.

[0027] Furthermore, the step of filling the guide rail adhesive involves applying the guide rail adhesive before the reference surface contacts the precision surface of the copying processing auxiliary device, or injecting the guide rail adhesive after the reference surface contacts the precision surface of the copying processing auxiliary device.

[0028] The beneficial effects of the copying processing auxiliary device and copying method disclosed in this invention are as follows:

[0029] A copying fixture is used to process the workpiece. A precision surface is designed on the fixture, serving as a reference surface. The first and second template surfaces are machined to match the precision surface, ensuring both templates have a certain level of accuracy. A guide rail adhesive copying method is employed. Before copying, the machined surface is polished to allow for the guide rail adhesive to fill. The guide rail adhesive and the precision surface are mated, with the precision of their interface equal to the precision surface's accuracy. The cured guide rail adhesive serves as the surface of the workpiece, effectively copying the precision surface's accuracy onto the workpiece's surface. This ensures that the surface accuracy of the machined workpiece matches the precision surface's accuracy, achieving the same precision for the workpiece's surface and guaranteeing its overall precision. Since both the first and second guide rail mounting surfaces of the slide saddle are copied using this precision surface, the accuracy of multiple guide rail mounting surfaces is ensured to be identical, guaranteeing equal machining precision and ensuring the contact and geometric accuracy between the slide saddle and the slide block.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the appendices in the embodiments of the present invention. Figure 1-4 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Reference Figure 1 A photocopying processing auxiliary device includes a mold base 1, a first template 2 and a second template 3, and an adjustment device 4 capable of mounting a slide saddle 5 on the mold base 1.

[0039] A precision surface 11 is machined on the upper surface of the mold base 1, and the first template 2 and the second template 3 are both set on the precision surface 11. There are two first templates 2, which are symmetrically arranged along the width direction of the mold base 1. The area of ​​the precision surface 11 located below the first template 2 is larger than the area of ​​the orthographic projection of the first template 2.

[0040] A mounting platform 31 is fixed on the mold base 1. The second template 3 is fixed on the precision surface 11 through the mounting platform 31. The mounting platform 31 is set along the width direction of the mold base 1, so that the second template 3 and the two first templates 2 form a U-shape with an opening on one side.

[0041] The first template 2 and the second template 3 are respectively machined with precision sub-surfaces that have the same geometric precision as the precision surface 11. Since the upper surface of the mold base 1, the plate surface of the first template 2, and the plate surface of the second template 3 are all exposed to the outside of the copy processing auxiliary device, there is no limitation on the processing space of the three surfaces, which facilitates the processing of the three surfaces. Through the setting of the precision surface 11 and the precision sub-surfaces, the copy processing auxiliary device can realize the copying of the precision surface 11 in different orientations.

[0042] The adjustment device 4 consists of five sets, with four sets located at the corners of the mold base 1 and one set located at the opening of the U-shape. The adjustment device enables positional adjustment of the workpiece in the X, Y, and X directions, improving the positioning accuracy between the workpiece and the copying auxiliary device.

[0043] The adjusting device 4 includes an adjusting block 41 and a bolt 42. The adjusting block 41 can tighten the workpiece to be processed by the bolt 42.

[0044] An adjustment component 43 is provided on the mold base 1 to adjust the distance between the adjustment block 41 and the mold base 1. The adjustment component 43 includes a vertically arranged screw 431 and a nut 432. The adjustment block 41 has a through hole for the screw 431 to pass through. Each screw 431 is fitted with two nuts 432, which are respectively located on the upper and lower sides of the adjustment block 41. The side of the nut 432 facing the adjustment block 41 is set with an arc-shaped end. When the nut is tightened, the arc-shaped end of the nut contacts the adjustment block. Under the action of the arc-shaped end, the center of the nut coincides with the center of the through hole, which improves the positioning accuracy of the screw. By using the nut 432 to pre-tighten the screw 431, the position of the adjustment block 41 is limited, so that the adjustment block 41 can press against the workpiece to be processed, thereby achieving pre-tightening of the workpiece. This makes it less likely for the workpiece to deviate in position during processing and improves the positioning accuracy between the workpiece to be processed and the copying fixture.

[0045] The screw 431 can also drive the adjusting block 41 to deflect, thereby adjusting the angle of the adjusting block 41. Through the cooperation of multiple sets of adjusting devices 4, the angle of the workpiece to be processed can be adjusted, which makes it easier to calibrate the processing surface of the workpiece and the precision surface 11 of the copy processing auxiliary device.

[0046] Example 2

[0047] Combination Figure 2 and Figure 3 The method of using a copying auxiliary device to copy a slide saddle specifically includes the following steps:

[0048] (1) The slide saddle includes the bottom surface of the guide rail connecting groove to be processed and the reference surface that has been processed. There are two guide rail connecting grooves. The bottom wall of one guide rail connecting groove is the first guide rail mounting surface 51 that mates with the slide ram guide rail. The bottom wall of the other guide rail connecting groove is the second guide rail mounting surface that mates with the column guide rail. The bottom wall of the guide rail connecting groove is ground to reduce the thickness of the bottom wall of the guide rail connecting groove by 1-2mm to obtain a ground surface. Generally, the ground surface is a rough surface. The contact surfaces on both sides of the slide saddle 5 are processed into reference surfaces 52 that are consistent with the precision surface.

[0049] (2) Hoist the slide saddle 5 above the copying auxiliary device and perform manual coarse calibration to align the reference surface of the slide saddle 5 with the precision surface 11 of the copying fixture. Align the polished surfaces with the corresponding first or second templates. The first template provides a reference for the first guide rail mounting surface, and the second template provides a reference for the second guide rail mounting surface. Apply a release agent to the surface of the first or second template, ensuring it is evenly applied to the precision surface 11. Then apply guide rail adhesive. Preferably, the thickness of the guide rail adhesive gradually decreases from the center to the edge of the corresponding surface. As the slide saddle 5 is lowered, the polished surface of the slide saddle 5 comes into contact with the guide rail adhesive, so that the guide rail adhesive is evenly filled between the precision surface 11 and the polished surface. At this time, the rough polished surface is used to bond with the guide rail adhesive. Then, the adjustment device is manually adjusted. The side of the slide saddle 5 is pressed by the adjustment blocks at different positions to adjust the position of the slide saddle 5 in the X and Y directions. Then, the slide saddle 5 is pressed by the bolts and adjustment blocks to make the reference surface of the slide saddle 5 and the precision surface 11 fit tightly together, thereby fixing the position of the slide saddle 5 in the Z direction. By limiting the X, Y and Z directions, the geometric accuracy and positioning accuracy between the slide saddle 5 and the mold base 1 are guaranteed.

[0050] (3) When the reference surface 52 of the slide saddle 5 is fully attached to the precision surface 11 on the copy processing auxiliary device, the surface coated with guide rail adhesive and the grinding surface cooperate to make the guide rail adhesive evenly distributed on the joint surface of the slide saddle 5 and the corresponding plate surface. Keep the slide saddle stationary in its original position until the guide rail adhesive is fully cured. Then the guide rail adhesive detaches from the plate surface and adheres to the grinding surface. The cured guide rail adhesive can completely cover the slide saddle 5. At this time, the contact surface between the guide rail adhesive and the precision surface serves as the guide rail mounting surface corresponding to the slide saddle 5. Under the action of the guide rail adhesive, the precision of the first template or the second template plate surface is copied onto the slide saddle 5, so that the precision of the new guide rail mounting surface is consistent with the precision of the precision surface. This achieves the synchronous processing of the two first guide rail mounting surfaces on both sides of the slide saddle 5 or the synchronous processing of the two second guide rail mounting surfaces, which not only ensures the processing accuracy but also improves the processing efficiency.

[0051] Example 3

[0052] The method of using a photocopying auxiliary device to copy a steel-insulated guide rail pressure plate specifically includes the following steps:

[0053] (1) The steel-inlaid guide rail pressure plate includes a fixed part and a guide rail mating part. The guide rail mating part is ground to reduce the thickness of the guide rail mating part of the steel-inlaid guide rail pressure plate by 1-2mm to obtain a ground surface. Generally, the ground surface is a rough surface. The fixed part is processed into a reference surface that is consistent with the precision surface.

[0054] (2) Hoist the steel-inlaid guide rail pressure plate above the precision surface 11 and perform manual rough calibration to ensure that the steel-inlaid guide rail pressure plate is aligned with the position of the precision surface 11 of the copying fixture. Apply a release agent to the precision surface 11, ensuring that the release agent is evenly applied. Then apply guide rail adhesive. Preferably, the thickness of the guide rail adhesive gradually decreases from the center to the edge of the corresponding precision surface 11. As the steel-inlaid guide rail pressure plate is lowered, the grinding surface and the guide rail adhesive come into contact, allowing the guide rail adhesive to evenly fill the space between the corresponding precision surface 11 and the grinding surface. At this point, the rough polished surface is used for bonding with the guide rail adhesive; then the adjustment device is manually adjusted, and the steel guide rail pressure plate is tightened by the adjustment blocks at different positions, adjusting the position of the steel guide rail pressure plate in the X and Y directions. Then, the steel guide rail pressure plate is pressed by bolts and adjustment blocks, so that the reference surface and precision surface 11 of the steel guide rail pressure plate are tightly fitted, thereby fixing the position of the steel guide rail pressure plate in the Z direction. By limiting the three directions of X, Y and Z, the geometric accuracy and positioning accuracy between the steel guide rail pressure plate and the mold base 1 are guaranteed.

[0055] (3) After the reference surface and the precision surface of the steel guide rail pressure plate are completely attached, the guide rail adhesive and the grinding surface are matched to keep the steel guide rail pressure plate stationary in its original position until the guide rail adhesive is fully cured. Then the guide rail adhesive is separated from the plate surface and adheres to the grinding surface. The cured guide rail adhesive can completely cover the guide rail mating part. At this time, the contact surface between the guide rail adhesive and the precision surface serves as the guide rail mating part. Under the action of the guide rail adhesive, the precision guide rail mating part of the precision surface is aligned with the precision of the new guide rail mating part, so that the surface precision of the new guide rail mating part is consistent with the precision of the precision surface.

[0056] Example 4

[0057] Reference Figure 4 The method of using a copy processing auxiliary device to copy the insert strip specifically includes the following steps:

[0058] (1) Make a mounting block 6 with a reference surface: The mounting block 6 is machined with an inclined surface 61 and a plane 62, the inclination angle of which is opposite to that of the inclination angle of the strip; the plane 62 is ground into a reference surface, the accuracy of which is equal to that of the accuracy surface 11; the strip 7 is installed on the inclined surface 61 of the mounting block by bolts, the surface of the installed strip 7 is close to the reference surface of the mounting block 6, the surface of the strip is ground to reduce the thickness of the strip by 1-2mm, the surface of the strip 7 is lower than the plane 62 of the mounting block 6, and a ground surface is obtained. Generally, the ground surface is a rough surface.

[0059] (2) The mounting block 6 with the insert is hoisted to the top of the copy processing auxiliary device and manually coarsely calibrated so that the mounting block 6 and the insert 7 are aligned with the precision surface 11 of the copying fixture. The release agent is evenly applied to the area where the precision surface 11 and the insert 7 are to overlap. Then the guide rail adhesive is applied. Preferably, the thickness of the guide rail adhesive gradually decreases from the center to the edge of the area where the precision surface 11 and the insert 7 overlap. As the insert is lowered, the polishing surface and the guide rail adhesive come into contact, so that the guide rail adhesive is evenly filled between the precision surface 11 and the polishing surface. At this time, the rough polishing surface is used to bond with the guide rail adhesive. Then the adjustment device is manually adjusted. The mounting block is tightened by adjusting blocks at different positions to calibrate the position of the mounting block in the X and Y directions. Then the mounting block is pressed by bolts and adjusting blocks to make the reference surface of the mounting block and the precision surface 11 fit tightly together, thereby fixing the position of the mounting block in the Z direction. By limiting the X, Y and Z directions, the geometric accuracy and positioning accuracy between the mounting block and the mold base 1 are guaranteed.

[0060] (3) When the reference surface and the precision surface of the mounting block are completely attached, the guide rail adhesive and the polished surface cooperate to keep the insert stationary in its original position until the guide rail adhesive is fully cured. Then the guide rail adhesive detaches from the plate surface and adheres to the polished surface. The cured guide rail adhesive can completely cover the guide rail mating part. At this time, the contact surface between the guide rail adhesive and the precision surface acts as the insert. Under the action of the guide rail adhesive, the insert on the precision surface is placed, so that the surface precision of the new insert is consistent with the precision surface precision.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
