A main spindle housing based on mineral casting

Abstract

This utility model discloses a spindle box based on mineral casting. It includes a base and a spindle sleeve. Several inserts are fixedly connected circumferentially to the side wall of the base near the sleeve and to the outer peripheral wall of the sleeve. A reference rod is fixedly connected to the end of one of the inserts on the side of the sleeve near the base, and one end of the reference rod is movably connected to the base to adjust the vertical, horizontal, and vertical position of the sleeve via the inserts. This mineral casting-based spindle box solves the technical problem that traditional positioning methods often rely solely on mechanical tooling fixtures or simple locating pin structures. In these methods, relative displacement easily occurs between the sleeve and the spindle box during the high-temperature liquid casting stage, leading to insufficient fitting accuracy between the spindle box and the sleeve after cooling and forming, thus affecting the overall performance of the machine tool.

Description

Technical Field

[0001] This utility model relates to the field of spindle box technology, specifically a spindle box based on mineral casting. Background Technology

[0002] In the field of mechanical manufacturing, the spindle box, as a core component of machine tools, directly affects the machining accuracy and operational stability of the machine tool due to its structural precision and assembly quality. In recent years, mineral casting technology has gradually become an important technological direction in spindle box manufacturing due to its advantages such as high forming precision, excellent material properties, energy saving, and environmental protection. Mineral casting uses specially formulated mineral materials to replace traditional metal materials, effectively reducing energy consumption and environmental pollution during the casting process while ensuring structural strength.

[0003] However, in the production of spindle boxes based on mineral castings, the precise positioning of the bushing and spindle box within the casting mold has always constrained product quality and production efficiency. Traditional positioning methods often rely solely on mechanical tooling fixtures or simple locating pin structures. However, due to the fluidity changes and solidification shrinkage of mineral materials during casting, the bushing and spindle box are prone to relative displacement during the high-temperature liquid casting stage. This results in insufficient fitting accuracy between the spindle box and bushing after cooling and forming, thus affecting the overall performance of the machine tool.

[0004] Therefore, it is necessary to provide a spindle box based on mineral casting to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a spindle box based on mineral casting to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a spindle box based on mineral casting, including a base and a spindle sleeve. Several plugs are fixedly connected to the side wall of the base near the sleeve and the outer peripheral wall of the sleeve along the circumferential direction. A reference rod is fixedly connected to the end of the plug on the side of the sleeve near the base towards the base. One end of the reference rod is movably connected to the base so as to adjust the up, down, left and right position of the sleeve through the plugs.

[0007] The base is connected to a casting body on the side near the bushing, a part of the bushing is located inside the casting body, and the reference rod is also located inside the casting body.

[0008] Furthermore, the bushing has two rows of inserts, one above the other. The inserts closest to the base are an upper connector and a lower connector, with the upper connector above the lower connector. The reference rod is also divided into an upper reference rod and a lower reference rod. The end of the upper connector is fixedly connected to one end of the upper reference rod, and the end of the lower connector is fixedly connected to one end of the lower reference rod.

[0009] Furthermore, a track is threaded vertically to the side of the base near the bushing, and a slider is slidably connected to the track. Both the track and the slider are located within the cast body.

[0010] Furthermore, one end of the upper reference rod is threaded with a first upper hexagonal nut and a second upper hexagonal nut, and one end of the lower reference rod is threaded with a first lower hexagonal nut and a second lower hexagonal nut. The upper and lower reference rods are slidably connected to the slider. The adjacent end faces of the first and second upper hexagonal nuts abut against the slider, and the adjacent end faces of the first and second lower hexagonal nuts abut against the slider.

[0011] Furthermore, a fastener is threaded onto one side of the slider, and the fastener is located between the upper reference rod and the lower reference rod.

[0012] Furthermore, the fastener has a rotating part, a screw part, and a supporting part, the screw part being located between the rotating part and the supporting part, the screw part being threadedly connected to the slider, and the rotating part being on the outside of the slider.

[0013] Furthermore, a hollow portion is formed between the bottom of the slider and the track, and the supporting portion is located inside the hollow portion. The supporting portion is circular and its diameter is larger than that of the screw portion.

[0014] Furthermore, one end of the plug connected to the base is located within the casting body, and one end of the plug connected to the bushing is located within the casting body.

[0015] The beneficial effects of this utility model are as follows: The spindle box based on mineral casting provided by this utility model has a supporting part in the hollow part to fix the slider on the track, thereby fixing the position of the bushing and preventing displacement. After the casting body is formed, the casting body formed in the hollow part allows the slider to be embedded in it, which increases its stability and improves casting efficiency.

[0016] By setting a slider that slides with a track, the bushing and the base can slide up and down to adjust the height between the bushing and the base. By setting a reference rod, the bushing and the slider can slide left and right to adjust the distance between the bushing and the base, making the positioning of the bushing and the base more accurate.

[0025] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] like Figure 1-4As shown, the present invention provides a technical solution: a spindle box based on mineral casting, including a base 1 and a spindle sleeve 2. Several inserts 4 are fixedly connected to the side wall of the base 1 near the sleeve 2 and the outer peripheral wall of the sleeve 2 along the circumferential direction. A reference rod is fixedly connected to the end of the insert 4 located on the side of the sleeve 2 near the base 1 towards the base 1. One end of the reference rod is movably connected to the base 1 so as to adjust the up, down, left and right position of the sleeve 2 through the insert 4.

[0028] The base 1 is connected to the casting body 3 on the side near the bushing 2. A part of the bushing 2 is located inside the casting body 3, and the reference rod is also located inside the casting body 3.

[0029] The bushing 2 has two rows of inserts 4, one above the other. The inserts 4 closest to the base 1 are the upper connector 41 and the lower connector 42. The upper connector 41 is above the lower connector 42. The reference rod is also divided into an upper reference rod 8 and a lower reference rod 9. The end of the upper connector 41 is fixedly connected to one end of the upper reference rod 8, and the end of the lower connector 42 is fixedly connected to one end of the lower reference rod 9.

[0030] A track 5 is threaded vertically on the side of the base 1 near the bushing 2, and a slider 6 is slidably connected on the track 5. Both the track 5 and the slider 6 are located inside the cast body 3.

[0031] One end of the upper reference rod 8 is threaded with a first upper hexagonal nut 81 and a second upper hexagonal nut 82, and one end of the lower reference rod 9 is threaded with a first lower hexagonal nut 91 and a second lower hexagonal nut 92. The upper reference rod 8 and the lower reference rod 9 are slidably connected to the slider 6. The adjacent end faces of the first upper hexagonal nut 81 and the second upper hexagonal nut 82 abut against the slider 6, and the adjacent end faces of the first lower hexagonal nut 91 and the second lower hexagonal nut 92 abut against the slider 6.

[0032] The fastener 7 has a rotating part 71, a screw part 72 and a holding part 73. The screw part 72 is located between the rotating part 71 and the holding part 73. The screw part 72 is threadedly connected to the slider 6. The rotating part 71 is on the outside of the slider 6.

[0033] A hollow portion 61 is formed between the bottom of the slider 6 and the track 5. The supporting portion 73 is located inside the hollow portion 61. The supporting portion 73 is circular and its diameter is larger than that of the screw portion 72.

[0034] One end of the plug 4 connected to the base 1 is located inside the casting body 3, and the other end of the plug 4 connected to the bushing 2 is located inside the casting body 3.

[0035] In one embodiment, the spindle box is cast as follows.

[0036] Specifically, the base 1 with the plug-in 4 connected is placed inside the casting mold. The rail 5 is connected to the base 1 using threads. The bushing 2 with the plug-in 4 connected is also placed inside the mold. The bushing 2 is rotated so that the upper connector 41 connected to the upper reference rod 8 and the lower connector 42 connected to the lower reference rod 9 face the base 1. The first upper hexagonal nut 81 is put into the upper reference rod 8, and the first lower hexagonal nut 91 is put into the lower reference rod 9. Then, the upper reference rod 8 and the lower reference rod 9 are passed through the slider 6. The upper reference rod 8 and the lower reference rod 9 are slid left and right to determine the left and right positions of the bushing 2. After the positions are determined, the second upper hexagonal nut 82 is put into the upper reference rod 8, and the second lower hexagonal nut 92 is put into the lower reference rod 9. The slider 6 is then fixed to the first upper hexagonal nut 81 and the second upper hexagonal nut 82. Between the first lower hexagonal nut 91 and the second lower hexagonal nut 92, slide the slider 6 from the top of the track 5, so that the bushing 2 also descends. When the bushing 2 reaches the predetermined height, the operator turns the rotating part 71 to move the supporting part 73 closer to the track 5 until it abuts against the track 5, thereby fixing the slider 6 on the track 5. At the same time, the position of the bushing 2 is also determined by the upper reference rod 8 and the lower reference rod 9. Subsequently, when casting the mineral medium, the bushing 2 is fixed in position by the supporting part 73, and no displacement will occur during the casting process. The cast mineral medium will also flow into the hollow part 61. After casting, the base 1, the main shaft bushing 2 and the casting body 3 are connected together, and the slider 6 is embedded in the casting body 3.

[0037] In summary, this device fixes the slider 6 to the track 5 by providing a supporting part 73 inside the hollow part 61, thereby fixing the position of the bushing 2 and preventing displacement. After the casting body 3 is formed, the slider 6 is embedded in the casting body 3 formed inside the hollow part 61, increasing its stability and improving casting efficiency. By providing a slider 6 that is slidably connected to the track 5, the bushing 2 and the base 1 can slide up and down to adjust the height between the bushing 2 and the base 1. By providing a reference rod, the bushing 2 and the slider 6 can slide left and right to adjust the distance between the bushing 2 and the base 1, making the positioning of the bushing 2 and the base 1 more accurate. This solves the technical problem that traditional positioning methods often use mechanical tooling fixtures or simple positioning pin structures, but due to the fluidity changes and solidification shrinkage of mineral materials during casting, the bushing and the spindle box are prone to relative displacement during the high-temperature liquid casting stage, resulting in insufficient matching accuracy between the spindle box and the bushing after cooling and forming, which in turn affects the overall performance of the machine tool.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
