Abstract
Description
Technical Field
[0001] This utility model relates to the field of foot cup technology, and in particular to an adjustable foot cup for machine tools. Background Technology
[0002] Machine tool leveling feet are components used for leveling and adjusting supports of machine tools, equipment, or other heavy machinery. They are typically made of metal or plastic and function to adjust height and stabilize the machine. Traditional leveling feet have the following drawbacks: their design only provides vertical adjustment and lacks balancing, resulting in uneven force distribution and affecting the machine tool's balance and accuracy.
[0003] In view of this, Chinese utility model patent with publication number CN221159343U discloses a machine tool adjustable foot cup, including a chassis, an external threaded column, an adjusting nut, and a hexagonal head. The external threaded column is provided on the top of the chassis, and the adjusting nut is sleeved around the external threaded column. A conical groove is opened at the bottom of the chassis, and an insertion hole is opened through the upper end of the conical groove. An insertion rod is inserted into the insertion hole. A balance pad B is provided around the insertion rod near the lower end of the hexagonal head, and a balance pad A is provided around the insertion rod near the upper end of the adjusting nut. The balance pads B and A are staggered in height. The above structure not only has the function of vertical adjustment, but also has a balancing effect, making the force on the bottom of the machine tool more even, thus improving the balance and accuracy of the machine tool. However, the following problems exist: First, by applying external force to the hexagonal head to insert the insertion rod into the insertion hole with interference fit, and cooperating with the adjusting nut to fix the bottom of the machine tool between the balance pads A and B, this interference fit connection method is not firm and is prone to loosening.
[0004] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide an adjustable foot cup for machine tools, which addresses the shortcomings of the prior art and solves the problems of loose connection and difficulty in leveling the adjustable foot cup in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable foot cup for a machine tool, comprising a chassis, an externally threaded post at the upper end of the chassis, an adjusting nut being externally threaded onto the externally threaded post, a balance pad A and a balance pad B being provided above the adjusting nut, an internally threaded hole at the upper end of the adjusting nut, a plug rod being threadedly connected to the internally threaded hole, a hexagonal head at the upper end of the plug rod, the lower end of the hexagonal head being able to abut against the balance pad B, and an elastic anti-loosening washer being provided between the adjusting nut and the balance pad A.
[0007] By adopting the above technical solution, the insertion rod is connected to the external threaded column by thread, and anti-loosening washers are used to prevent the nut from rotating due to machine tool vibration and thus loosening, thereby improving the stability of the connection between the foot cup and the machine tool.
[0008] A further feature of the above technical solution is that micro-protrusion arrays are provided on the sides of the balance pads A and B that are close to each other.
[0009] By adopting the above technical solution, by setting a micro-protrusion array on the side of the balance pad A and balance pad B that are close to each other, the friction between the balance pad A and balance pad B and the bottom surface of the machine tool can be increased, thereby enhancing the anti-slip performance and avoiding damage to the bottom surface of the machine tool.
[0010] A further provision of the above technical solution is as follows: a balance bracket is provided between the balance pad A and the anti-loosening washer, the balance bracket has a clearance hole in the center that can pass through the external threaded post, mounting tubes are symmetrically provided on both sides of the balance bracket, the mounting tubes have mounting grooves, a bubble level is installed in the mounting grooves, and the mounting tubes are made of transparent material.
[0011] Using the above technical solution, the bubble level installed on the balance bracket can detect whether the machine tool is installed horizontally and whether the force is balanced, thus assisting in quick leveling.
[0012] A further provision of the above technical solution is that a cap is interference-fitted to one end of the opening of the mounting tube, and the end of the cap near the bubble level can abut against the side of the bubble level.
[0013] By adopting the above technical solution, the bubble level can be effectively fixed and protected by installing a cap on the mounting tube.
[0014] A further provision of the above technical solution is that a downwardly extending connecting portion is provided between the mounting tube and the balance bracket.
[0015] By adopting the above technical solution, the downward-extending connecting part allows the bubble level inside the mounting tube to be relatively far away from the bottom of the machine tool, thus making it convenient to view the bubble level.
[0016] A further provision of the above technical solution is that a tapered boss is provided at the top of the chassis near the external threaded column, and a reinforcing rib is provided at the corner where the bottom of the tapered boss connects to the chassis.
[0017] By adopting the above technical solution, the strength of the connection between the tapered boss and the chassis can be effectively improved by reinforcing ribs.
[0018] A further feature of the above technical solution is that a mounting hole is provided through the bottom of the chassis near the edge.
[0019] By using the above technical solution, external bolts are passed through the mounting holes, making it easy to fix the chassis to the ground.
[0020] A further provision of the above technical solution is that a conical groove is provided at the bottom of the chassis, and a weight-reducing groove is provided at the bottom of the chassis near the outer periphery of the conical groove.
[0021] By adopting the above technical solution, the overall material usage of the chassis can be effectively reduced through the conical groove and weight reduction groove, which helps to reduce the cost of this adjustable foot cup.
[0022] The beneficial effects achieved by this utility model are as follows: by connecting the insert rod with the external threaded column and by setting an anti-loosening washer, the problem of loosening caused by the self-rotation of the nut due to machine tool vibration can be avoided, thus improving the stability of the connection between the foot cup and the machine tool; by setting a balance bracket between the balance shim A and the anti-loosening washer and installing a bubble level on it, it is possible to detect whether the machine tool is installed horizontally and whether the force is balanced, thus assisting in quick leveling.
