Description

Technical Field

[0001] This utility model relates to the field of milling machine spindle technology, and more specifically, it relates to a milling machine spindle telescopic mechanism for machining mechanical equipment. Background Technology

[0002] A drilling and milling machine is a machining equipment that integrates drilling, milling, boring, and grinding. It is used for processing small and medium-sized parts. The most important part of a drilling and milling machine is the spindle. The cutting tool is mounted on the spindle, and the movement of the spindle can drive the cutting tool to move, thereby enabling the cutting tool to process the parts. In modern manufacturing, it is a key piece of equipment for realizing modern manufacturing. During the machining operation, the spindle needs to extend and retract to complete the machining operation, so a mechanical device with an extendable spindle is needed.

[0003] However, most existing spindles are telescopically moved by external transmission components. This type of spindle is not only more complicated in structure, but also tends to occupy more space inside the machine tool due to the large number of parts, resulting in poor practicality. Furthermore, the lack of a locking mechanism makes it difficult to fix the spindle after it has been adjusted to the appropriate height, affecting the accuracy of the tool during use. Utility Model Content

[0004] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides a telescopic mechanism for a milling machine spindle used in mechanical equipment processing. This solves the technical problem mentioned in the background art that most existing spindles rely on external transmission components for telescopic movement, and this structure, due to its numerous components, tends to occupy internal space of the machine tool, resulting in poor practicality.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a telescopic mechanism for a milling machine spindle used in machining, comprising a lower spindle body, both ends of which are fixedly provided with covers, and a slide rod is fixedly provided at the middle position of the two covers. The slide rod is provided in two sets and is arranged symmetrically from left to right. A telescopic shaft is slidably provided inside the lower spindle body. The telescopic shaft is slidably installed with one of the covers. A slider is fixedly provided on both sides of the upper end face of the telescopic shaft. The slider is slidably installed with the slide rod. A threaded sleeve is rotatably provided at the middle position of the other cover. A threaded rod is provided at the upper end of the telescopic shaft. The threaded rod is threadedly connected to the threaded sleeve. A base is provided at one end of the lower spindle body. A motor is provided on the outer wall of the base. Both the motor and the outer wall of the threaded sleeve are provided with bevel gears. The two bevel gears are meshed and installed. An upper spindle body is provided at the upper end of the lower spindle body. Both the lower spindle body and the upper spindle body are provided with clamping mechanisms.

[0006] The present invention is further configured such that the clamping mechanism includes an electric push rod, and the electric push rod is provided in two sets and is fixedly connected to the outer wall of the lower shaft and the upper shaft. The output end of the electric push rod is provided with a clamping block, and the clamping block is provided in two sets and is located on the upper and lower sides of the telescopic shaft, so as to facilitate clamping and fixing the telescopic shaft.

[0007] The present invention is further provided with anti-slip pads fixed on the inner wall of each clamping block, and the anti-slip pads abut against the outer wall of the telescopic shaft, so as to increase the friction between the clamping block and the telescopic shaft.

[0008] The present invention is further provided that the lower shaft and the upper shaft are provided with mounting grooves on their outer walls and at their bottoms, the inner walls of the mounting grooves are provided with external threads, and the mounting grooves are provided with fastening rings. The fastening rings are threadedly connected to the lower shaft and the upper shaft through the external threads, which facilitates the fixed installation of the bottom of the upper shaft and the lower shaft.

[0009] The present invention is further configured such that a first connecting block is provided at the other end of the lower shaft body, and two sets of the first connecting blocks are provided in a symmetrical arrangement. A second connecting block is provided at the other end of the upper shaft body. A connecting screw is provided at the connection position of the first connecting block and the second connecting block, so as to facilitate the fixed installation of the upper and lower shaft bodies.

[0010] The present invention is further provided that one end of each connecting screw is fixedly provided with a screwing block, which facilitates the disassembly and installation of the connecting screw.

[0011] The present invention is further configured such that one end of the telescopic shaft passes through the upper shaft body and the lower shaft body and is provided with an external bracket, which facilitates connection with the cutting tool.

[0012] The present invention is further configured such that both sides of the upper shaft are provided with mating grooves, and both sides of the lower shaft are provided with mating blocks. The mating blocks are located inside the mating grooves, which facilitates the mating of the upper shaft and the lower shaft and makes subsequent installation convenient.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a milling machine spindle telescopic mechanism for machining equipment, which has the following beneficial effects: 1. By setting up a lower shaft, a cover, a telescopic shaft, and a threaded sleeve, the user can control the motor to make the bevel gear drive the threaded sleeve to rotate, so that the threaded sleeve drives the threaded rod and the telescopic shaft to move up and down, thereby adjusting its telescopic length. This makes it convenient to use. Furthermore, since the transmission component is set inside and around the lower shaft, it saves more space and increases practicality.

[0014] 2. By setting up an upper shaft, an electric push rod, and a clamping block, after the telescopic shaft is adjusted, the user can control the electric push rod to move the clamping block by its output end, so that the anti-slip pad on the inner wall of the clamping block abuts against the outer wall of the telescopic shaft, thereby achieving the effect of locking and fixing it, which is convenient for subsequent use.

[0015] 3. By setting up an installation slot, a fastening ring, a first connecting block, and a second connecting block, the user can disassemble the device by rotating the fastening ring to remove it from the installation slot. Then, the user can unscrew the connecting screws by turning the blocks to separate the upper and lower shafts, facilitating the maintenance and lubrication of the internal components and contributing to long-term use.
