Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to an auxiliary lifting device for a milling machine worktable. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the rotation of the milling cutter is the primary motion, while the movement of the workpiece and the milling cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, and more.

[0003] A milling machine is a machine tool that uses a milling cutter to mill workpieces. In addition to milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also process relatively complex profiles. They are more efficient than planers and are widely used in mechanical manufacturing and repair departments.

[0004] Ordinary milling machines on the market typically use a hand crank to rotate the shaft, which in turn drives the lifting components inside the milling machine to control the raising and lowering of the worktable. This method is manual and has a low degree of automation.

[0005] Therefore, we propose an auxiliary lifting device for the milling machine table to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary lifting device for a milling machine worktable to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary lifting device for a milling machine worktable, comprising: a controller, the controller being electrically connected to a motor, and the motor being fixedly installed on one side of the milling machine worktable;

[0008] The output end of the motor is fixedly connected to the first sprocket, the first sprocket is connected to the transmission chain, the transmission chain is connected to the second sprocket, and the second sprocket is fixedly connected to the spindle of the hand crank of the milling machine worktable.

[0009] Preferably, the output end of the motor is movably fitted with a housing, which is also fixedly installed on one side of the milling machine worktable.

[0010] Preferably, the first sprocket is coaxially fixedly mounted with a timing pulley, and a locking component is fixedly connected to the side of the timing pulley.

[0011] Preferably, a dial is fixedly sleeved on the side of the synchronous pulley.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] It can be installed on existing ordinary milling machines. During installation, first remove the rocker arm and dial from the existing milling machine, then put the synchronous pulley on the shaft. The operating controller can control the shaft to rotate forward or backward, thereby controlling the worktable to rise or fall, so that the ordinary milling machine worktable can achieve automatic lifting and lowering.

[0019] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary lifting device for a milling machine worktable, comprising: a controller 1, which is electrically connected to a motor 2, and the motor 2 is fixedly installed on one side of the milling machine worktable;

[0021] The output end of motor 2 is movably fitted with housing 3, and housing 3 is also fixedly installed on one side of the milling machine worktable;

[0022] The output end of motor 2 is fixedly connected to the first sprocket 4, the first sprocket 4 is connected to the transmission chain 5, the transmission chain 5 is connected to the second sprocket 6, and the second sprocket 6 is fixedly connected to the spindle of the hand crank of the milling machine table, so as to realize the transmission of torque to the spindle of the hand crank of the milling machine table.

[0023] The controller 1 controls the motor 2 to work, which drives the first sprocket 4 to rotate, and then drives the second sprocket 6 to rotate through the transmission chain 5. The second sprocket 6 drives the spindle of the hand crank of the milling machine table to rotate, thereby realizing the auxiliary lifting of the milling machine table.

[0024] The first sprocket 4 is coaxially fixedly mounted with the synchronous pulley 7, and the locking piece 8 is fixedly connected to the side of the synchronous pulley 7;
