Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing devices, in particular to a multifunctional scraping and grinding tool suitable for guide rail surfaces and sliding block installation surfaces. Background Art
[0002] In the assembly process of machine tools, in order to achieve the accuracy of the guide rails, the method of scraping and grinding the guide rails is usually adopted. However, the current domestic CNC machine tools still choose the traditional method when scraping and grinding the guide rails, that is, using a flat ruler to run-in on the surface of one guide rail, and then scraping and grinding according to the running-in spots of this guide rail; the same method is used to scrape and grind the other guide rail. Although this process ensures that the two guide rail surfaces have a good fit with the flat ruler, it cannot guarantee the coplanarity accuracy between the two guide rails. The two guide rail surfaces will produce various distortions due to non-coplanarity, making it difficult to guarantee the accuracy of the guide rails, affecting the accuracy of the machine tool and the life of the guide rails; in addition, this structural method cannot simultaneously realize the scraping and grinding of the guide rail slider installation. On the other hand, the traditional guide rail scraping tooling cannot simultaneously guarantee the coplanarity accuracy of the two guide rail surfaces and the coplanarity accuracy of the four slider mounting surfaces, that is, the guide rail surface and the slider mounting surface require separate scraping tooling, which requires more production costs, and requires repeated scraping, which is time-consuming and labor-intensive.
[0003] Therefore, those skilled in the art are committed to developing a multifunctional scraping tool that can improve the scraping accuracy and can be applied to the guide rail surface and the slider mounting surface. Utility Model Content
[0004] In view of the above-mentioned defects of the prior art, the utility model discloses a multifunctional scraping and grinding tool, and the technical problem to be solved is to provide a multifunctional scraping and grinding tool which can improve the scraping and grinding accuracy and is applicable to the guide rail surface and the slider installation surface.
[0005] To achieve the above-mentioned purpose, the utility model provides a multifunctional scraping and grinding tool, including a tool body, the bottom of the tool body is provided with two mutually parallel first scraping and grinding protrusions, each of the first scraping and grinding protrusions is provided with a guide rail running-in surface; the top of the tool body is provided with a second scraping and grinding protrusion, and the second scraping and grinding protrusion is provided with a slider running-in surface.
[0006] The working principle of the multifunctional scraping tool of the utility model is:
[0007] When it is necessary to scrape a machine tool with dual guide rails, place the scraping tool on the machine tool, and make each guide rail running-in surface contact the guide rail surfaces of the two guide rails of the machine tool respectively. By moving the scraping tool in parallel, the guide rail surfaces of the two guide rails can be scraped at the same time, and the coplanarity of the two guide rail surfaces can be guaranteed at the same time. When it is necessary to scrape a large column with four slider mounting surfaces, lay the scraping tool flat, place the large column on the scraping tool, and make the slider running-in surface contact the four slider mounting surfaces of the large column respectively. By moving the large column in parallel, the four slider mounting surfaces can be scraped at the same time, and the coplanarity of the four slider mounting surfaces can be guaranteed at the same time. By combining the scraping of two components on one tool, it is not only convenient for material management, but also greatly reduces the production cost of the tool.
[0008] Preferably, due to the long length of the guide rail, the first scraping protrusion is arranged along the length direction of the tooling body, and when scraping the guide rail, the scraping tooling needs to be pushed back and forth parallel to the length direction of the tooling body; the slider mounting surface of the large column is small, and the second scraping protrusion is arranged along the width direction of the tooling body. When scraping the slider mounting surface of the large column, the large column needs to be pushed back and forth parallel to the width direction of the tooling body.
[0009] Preferably, the number of the second scraping protrusions is at least two, and each second scraping protrusion is responsible for scraping two slider mounting surfaces. For equipment with more slider mounting surfaces, the number of second scraping protrusions can be set as needed.
[0010] Preferably, the tool body includes an upper top plate, and side plates are respectively extended vertically downward on both sides of the long sides of the upper top plate, the first scraping protrusion is arranged at the bottom of the side plate, and the second scraping protrusion is arranged on the upper top plate.
[0011] Preferably, connecting plates are respectively extended vertically downward on both sides of the short sides of the upper top plate, and the connecting plates are connected to both the side plates and the first scraping protrusions.
[0012] Preferably, the upper top plate, the side plate, the connecting plate, the first scraping protrusion and the second scraping protrusion are integrally formed.
[0013] Preferably, a lifting plate is provided on the outer side of the side plate, and a lifting ring is provided on the lifting plate. The lifting plate is separated from the tooling to avoid the stress generated at the lifting ring affecting the accuracy of the tooling. The lifting ring is located at the center of gravity of the tooling, which is conducive to leveling the tooling. The lifting plate is also provided with a step hole, and a step screw connected to the side plate is provided in the step hole. By providing the step hole and the step screw, a gap is provided between the lifting plate and the tooling, thereby avoiding the lifting stress from affecting the tooling.
[0014] Preferably, reinforcing ribs are provided in the internal space enclosed by the upper top plate, the side plates and the connecting plates. The shapes enclosed by the reinforcing ribs are circular, square, special-shaped, etc., and are specifically designed according to the needs of the tooling structure.

The placement surface is used to place a spirit level to facilitate level adjustment in two directions.
[0016] The scraping tool of the utility model is cast with HT300, and the internal reinforcing ribs are evenly distributed. It needs to be evenly cooled during casting to ensure that the stress is fully released. After semi-finishing, it needs to undergo secondary aging treatment to fully eliminate residual stress and ensure the stability of the tool so that it has long-term accuracy stability. After finishing, the guide rail running-in surface and the slider running-in surface need to be scraped on a 00-grade flat plate respectively to achieve high plane accuracy. At the same time, the scraping surface needs to be regularly tested for accuracy to ensure the accuracy of its accuracy.

[0026] like Figure 1 and Figure 2 As shown, the utility model provides a multifunctional scraping tool 10, including a tool body, the tool body including an upper top plate 1, side plates 2 extending vertically downward on both sides of the long sides of the upper top plate 1, a first scraping protrusion 21 is provided at the bottom of the side plate 2, and a second scraping protrusion 11 is provided on the upper top plate 1. At the same time, connecting plates 3 extending vertically downward on both sides of the short sides of the upper top plate 1 are connected to the side plates 2 and the first scraping protrusion 21. In order to strengthen the strength of the entire scraping tool, the upper top plate 1, the side plates 2, the connecting plates 3, the first scraping protrusion 21 and the second scraping protrusion 11 are integrally formed.
[0027] Furthermore, the two first scraping protrusions 21 arranged at the bottom of the tooling body are parallel to each other, and each first scraping protrusion 21 is respectively provided with a guide rail running-in surface 211; the second scraping protrusion 11 arranged at the top of the tooling body is provided with a slider running-in surface 111. Due to the long length of the guide rail, the first scraping protrusion 21 is arranged along the length direction of the tooling body. When scraping the guide rail, it is necessary to push the scraping tooling 10 back and forth in parallel along the length direction of the tooling body; the slider mounting surface of the large column 30 is small, and the second scraping protrusion 11 is arranged along the width direction of the tooling body. When scraping the slider mounting surface of the large column 30, it is necessary to push the large column 30 back and forth in parallel along the width direction of the tooling body. The number of the second scraping protrusions 11 is at least two, and in this embodiment, there are two. Each second scraping protrusion 11 is responsible for scraping two slider mounting surfaces. For equipment with more slider mounting surfaces, the number of second scraping protrusions 11 can be set as needed.
[0028] At the same time, a reinforcing rib 5 is provided in the internal space surrounded by the upper top plate 1, the side plate 2 and the connecting plate 3. The shape surrounded by the reinforcing rib 5 is round, square, special-shaped, etc., which is specifically designed according to the needs of the tooling structure, and the reinforcing rib 5 is also integrally formed. In addition, a placement surface is also provided on the upper surface of the upper top plate 1. The placement surface is parallel to the guide rail running-in surface 211 and the slider running-in surface 111. The placement surface is used to place a level gauge to facilitate level adjustment in two directions.
[0029] The working principle of the multifunctional scraping tool of the utility model is:
[0030] like Figures 3 to 5 As shown, when it is necessary to scrape and grind a machine tool 20 with dual guide rails, the scraping and grinding tool 10 is placed on the machine tool 20, and each guide rail running-in surface 211 is respectively in contact with the guide rail surfaces of the two guide rails of the machine tool 20. By moving the scraping and grinding tool 10 in parallel, the guide rail surfaces of the two guide rails can be scraped and grinded at the same time, and the coplanarity of the two guide rail surfaces can be guaranteed at the same time. When it is necessary to scrape and grind a large column 30 with four slider mounting surfaces, the scraping and grinding tool 10 is laid flat, the large column 30 is placed on the scraping and grinding tool 10, and the slider running-in surface 111 is correspondingly in contact with the four slider mounting surfaces of the large column 30. By moving the large column 30 in parallel, the four slider mounting surfaces can be scraped and grinded at the same time, and the coplanarity of the four slider mounting surfaces can be guaranteed at the same time. By combining the scraping and grinding of the two components on one tool, it is not only convenient for material management, but also greatly reduces the production cost of the tool.
[0031] In the above embodiments, by integrating the scraping and grinding of two components into one tool, one tool can complete the scraping and grinding of two surfaces, conveniently showing non-coplanar spots, and can quickly scrape and grind the two guide rail surfaces and the four slider mounting surfaces, while ensuring the mutual coplanar accuracy respectively, which not only greatly reduces the number of tooling requirements, saves the storage space of the tooling, facilitates the management of the tooling, and greatly reduces the production cost of the tooling. Compared with the traditional single guide rail surface running-in, the scraping and grinding tool of the utility model has the advantages of high efficiency, high precision, time saving and labor saving, solves the stress caused by the non-coplanarity of the two guide rails and the non-coplanarity of the four slider mounting surfaces in the existing assembly, improves the repeated positioning accuracy of the moving axis, reduces the wear of the guide rails, improves the processing reliability, and increases the service life of the guide rails.
[0032] like Figure 2 As shown, a lifting plate 4 is provided on the outer side of the side plate 2, and a lifting ring 41 is provided on the lifting plate 4. The lifting plate 4 is separated from the tooling to prevent the stress generated at the lifting ring 41 from affecting the accuracy of the tooling. The lifting ring 41 is located at the center of gravity of the tooling, which is conducive to leveling the tooling. The lifting plate 4 is also provided with a step hole 42, and a step screw connected to the side plate 2 is provided in the step hole 42. By providing the step hole 42 and the step screw, there is a gap between the lifting plate 4 and the tooling, thereby preventing the lifting stress from affecting the tooling.
[0033] The scraping tool of the utility model is cast with HT300, and the internal reinforcement ribs 5 are evenly distributed. Uniform cooling is required during casting to ensure sufficient stress release. After semi-finishing, it needs to undergo secondary aging treatment to fully eliminate residual stress and ensure the stability of the tooling, so that it has long-term precision stability. After finishing, the guide rail running-in surface and the slider running-in surface need to be scraped on a 00-grade flat plate respectively to achieve high plane accuracy. At the same time, the scraping surface needs to be regularly tested for accuracy to ensure the accuracy of its precision.
