Description

Technical Field

[0001] The utility model relates to the technical field of machine tool feet, in particular to an adjustable foot for a machine tool. Background Art

[0002] As the core equipment in the manufacturing industry, machine tools undertake various precision processing tasks. In order to ensure the processing accuracy, machine tools must have a high degree of stability and adaptability to the processing environment. In practical applications, due to the unevenness of the workplace floor or the diversity of the workpieces being processed, the height adjustment of the bottom of the machine tool becomes a key factor in ensuring the processing quality. The height adjustment is not only related to the horizontal state of the machine tool, but also directly affects the relative position accuracy between the cutting tool and the workpiece. At present, the methods of height adjustment mainly include mechanical screw adjustment, hydraulic adjustment and electric drive adjustment. Among them, mechanical screw adjustment is widely used due to its simple structure and low cost, but this method often cannot fully meet the needs of high-precision processing in terms of accuracy and ease of operation. Although hydraulic adjustment and electric drive adjustment improve the accuracy and convenience of adjustment, the cost is relatively high and the maintenance is more complicated.

[0003] In the traditional design of machine tool foundation, the structure of the foundation is usually simple, and a static support design is mostly adopted, which makes it extremely difficult to adjust the height after the machine tool is installed. In most cases, the operator needs to pre-adjust the height before the machine tool is fully placed on the foundation. Once the machine tool is placed and fixed, adjusting the foundation is not only time-consuming and labor-intensive, but may also affect the stability of the machine tool. For example, if the foundation adopts a traditional screw adjustment design, under the action of the gravity of the machine tool, it will be difficult to rotate the adjustment screw, and it is difficult to achieve the ideal adjustment accuracy. Therefore, in view of the shortcomings of the existing technology, a new type of machine tool foundation design is urgently needed to solve the convenience and precision control problems of height adjustment.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0030] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense, for example, it can be fixed connection, setting, or detachable connection, setting, or integrated connection, setting. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0032] See also Figure 1-5 As shown, the utility model provides a technical solution of an adjustable foot for a machine tool: an adjustable foot for a machine tool, comprising a chassis 1, an upper end surface of the chassis 1 is provided with a height adjustment mechanism 2, and an inner side of the chassis 1 is provided with a fixing mechanism 3 for limiting the movement of the height adjustment mechanism 2;

[0033] The height adjustment mechanism 2 includes a screw 201, a support 202, and a turntable 203. The screw 201 is fixedly connected to the upper end of the chassis 1. The support 202 is connected to the screw 201 by threading. The turntable 203 is fixedly installed on the upper end surface of the support 202. When the height of the machine tool is adjusted, the support 202 needs to be rotated. At this time, the support 202 moves up and down along the screw 201, and the machine tool will also change in height following the movement of the support 202. In this process, since the turntable 203 is installed between the support 202 and the machine tool, the friction can be greatly reduced, and the operator's turning force on the support 202 can be reduced.

[0034] The fixing mechanism 3 includes a plurality of grooves 301, a first rotating plate 302, a second rotating plate 303, and a plurality of recessed slots 307. The groove 301 is provided on the inner side of the chassis 1. The first rotating plate 302 is rotatably connected to the side wall of the groove 301. The first rotating plate 302 and the second rotating plate 303 are rotatably connected by installing a central axis rod 304. The upper end surface of the central axis rod 304 is connected to an anti-slip plate 305. The other end of the second rotating plate 303 is rotatably connected to a push plate 306. The recessed slot 307 is provided on the upper end surface of the groove 301. A plug plate 308 is detachably arranged on the inner side of the recessed slot 307. The plug plate 308 is used to limit the push plate 306. Move to the outside of the groove 301. During the specific implementation process, the top of the anti-skid plate 305 can be coated with anti-skid paint or set with anti-skid rubber to achieve an anti-skid effect on the contact surface with the support member 202. When the support member 202 is adjusted to a suitable height, it needs to be restricted to prevent it from rotating. At this time, the operator needs to press the push plate 306, and the anti-skid plate 305 located in the middle of the two rotating plates will be lifted up. When the anti-skid plate 305 is against the bottom of the support member 202, the plug plate 308 is inserted into the recessed slot 307 to lock the push plate 306, prevent the anti-skid plate 305 from dropping in height, and prevent the support member 202 from rotating to achieve a fixing effect.

[0035] The screw 201 and the support member 202 are both made of hard metal to ensure durability and anti-deformation ability under high-intensity pressure. In the specific implementation process, the hard metal that can be selected includes but is not limited to cemented carbide, high-speed steel, tool steel, etc. These materials can effectively resist deformation and wear caused by high pressure.

[0036] The side of the support member 202 is provided with a hexagonal portion 4. By providing the hexagonal portion 4, the tool can evenly apply torque to the support member 202, thereby achieving efficient rotation and quickly adjusting the height of the foot.

[0037] The upper end surface of the support member 202 is provided with a positioning ring 5, which can be used for alignment when placing the machine tool, so that the positioning hole at the bottom of the machine tool can be accurately placed on the turntable 203 through the positioning ring 5.

[0038] Pressure-bearing parts 6 are provided at both the upper and lower ends of the support member 202. The pressure-bearing part 6 at the upper end of the support member 202 can increase the force-bearing area to facilitate the placement of a larger turntable 203. On the one hand, the pressure-bearing part 6 at the lower end can provide sufficient force-bearing area when it is directly placed on the chassis 1. On the other hand, after the height is adjusted, the pressure-bearing part 6 at the lower end of the support member 202 can have sufficient bottom area to contact the anti-slip plate 305 of the fixing mechanism 3, thereby ensuring that under different height conditions, the bottom of the support member 202 can contact the anti-slip plate 305 to prevent rotation.

[0039] The working principle of the utility model is as follows:

[0040] When adjusting the height of a machine tool using an adjustable foot of the present embodiment, the operator needs to rotate the support 202. At this time, the height of the machine tool located above the support 202 will be adjusted, and the turntable 203 can reduce the friction between the machine tool and the support 202, making it easier for the operator to rotate the support 202. When the machine tool reaches a predetermined height, the operator needs to press the push plate 306. At this time, the anti-skid plate 305 located in the middle of the two turn plates will be lifted up. When the anti-skid plate 305 is against the bottom of the support 202, the insert plate 308 is inserted into the recessed slot 307 to lock the push plate 306, prevent the anti-skid plate 305 from decreasing in height, and prevent the support 202 from rotating, thereby finally achieving a fixing effect on the height of the machine tool.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
