Description

Technical Field

[0001] This utility model belongs to the field of machine tool spindle technology, specifically relating to a machine tool spindle that is easy to maintain. Background Technology

[0002] The machine tool spindle is a crucial component of a machine tool, primarily used to mount workpieces or cutting tools and to achieve rotary motion during the cutting process. The spindle's performance directly impacts key machine tool indicators such as working accuracy, machining efficiency, and surface finish. Based on their drive method, machine tool spindles can be broadly classified into two categories: mechanical spindles and electric spindles.

[0003] Existing machine tool spindles are usually fixed to the surface of the reducing sleeve. When the machine tool spindle is overhauled, the machine tool spindle and the reducing sleeve need to be disassembled together. This is inconvenient for disassembling and overhauling the machine tool spindle, reduces the efficiency of machine tool spindle overhaul, and wastes time and human resources. Utility Model Content

[0004] The purpose of this invention is to provide a machine tool spindle that is easy to maintain, in order to solve the problem that in the prior art, the machine tool spindle is usually fixed on the surface of the reducing sleeve. When the machine tool spindle is maintained, it is necessary to disassemble the machine tool spindle and the reducing sleeve together, which is inconvenient for disassembling and maintaining the machine tool spindle, reduces the efficiency of the machine tool spindle maintenance work, and causes a waste of time and human resources.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A machine tool spindle that is easy to maintain includes:

[0007] Machine tool spindle body;

[0008] A variable diameter sleeve is fitted onto the outer surface of the machine tool spindle body;

[0009] A tapered seat, which is fixedly connected to one side of a reducing sleeve, and a tapered sleeve is threaded onto the outer surface of the tapered seat;

[0010] A sliding groove is provided on one side of the variable diameter sleeve, and an extrusion groove is provided on the inner wall of one side of the sliding groove.

[0011] The connecting mechanism includes:

[0012] Two snap-fit ​​blocks are fixedly connected to the outer surface of the machine tool spindle body, and the outer surface of the machine tool spindle body is slidably connected to the inner surface of the sliding groove and the extrusion groove.

[0013] Two snap-fit ​​slots, each formed on one inner wall of the extrusion groove, with the outer surfaces of the two snap-fit ​​slots and the outer surfaces of the two snap-fit ​​blocks slidably connected; and

[0014] A limiting component is provided in the compression groove to limit the movement of the two sliding locking blocks.

[0015] As a preferred embodiment of this utility model, the limiting component includes:

[0016] A spring is disposed on the inner surface of the extrusion groove, and a limiting seat and a limiting block are slidably connected to the inner surface of the extrusion groove, with the adjacent ends of the limiting seat and the limiting block being fixedly connected.

[0017] In a preferred embodiment of this utility model, the inner surface of the extrusion groove is provided with a plurality of limiting grooves, the inner surfaces of the plurality of limiting grooves are slidably connected to limiting blocks, and the outer surfaces of the plurality of limiting blocks and the outer surface of the extrusion seat are fixedly connected.

[0018] In a preferred embodiment of this utility model, a fixed seat is fixedly connected to the inner wall of the other side of the extrusion groove. The inner surface of the fixed seat and the outer surface of the spring are slidably connected, and the outer surface of the fixed seat is trapezoidal in shape.

[0019] As a preferred embodiment of this utility model, two mounting grooves are provided on one side of the variable diameter sleeve, and multiple friction strips are slidably connected to the inner surfaces of the two mounting grooves.

[0020] As a preferred embodiment of this utility model, two mounting blocks are fixedly connected to one side of each of the plurality of friction strips, and two screws are threaded to one side of each of the two mounting blocks.

[0021] As a preferred embodiment of this utility model, the inner surface of the conical seat is provided with a plurality of compression pads.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. In this solution, the machine tool spindle body is inserted into the sliding groove and the extrusion groove. Then, the machine tool spindle body is rotated 90 degrees. Under the action of the spring elastic force, the extrusion seat is pushed outward, causing the two locking blocks to slide into the two locking grooves respectively, thus completing the installation of the machine tool spindle body. When disassembling the machine tool spindle body, the machine tool spindle body is pushed inward. At this time, the two locking blocks slide out of the two locking grooves respectively. Then, the machine tool spindle body is rotated 90 degrees. At this time, the outer surface of the machine tool spindle body matches the inner surface of the sliding groove, thereby removing the machine tool spindle body from the sliding groove and the extrusion groove, completing the disassembly of the machine tool spindle body. This facilitates the maintenance of the machine tool spindle body. When the machine tool spindle is maintained, it is not necessary to disassemble the machine tool spindle and the reducing sleeve together, which facilitates the disassembly and maintenance of the machine tool spindle, improves the efficiency of the machine tool spindle maintenance work, and reduces the waste of time and human resources.

[0024] 2. In this design, the mounting groove is located on one side of the reducing sleeve, providing a mounting position for the friction strip. This allows the friction strip to effectively increase friction, help stabilize the mounting block, and prevent loosening due to vibration or other reasons. Attached Figure Description

[0052] In this embodiment, the fixing seat 15 is fixed to the inner wall of the other side of the extrusion groove 7, providing a support point for the spring 14. At the same time, its trapezoidal design helps to disperse pressure and improve durability.

[0053] Please refer to the details. Figure 5 and Figure 6 Two mounting grooves 8 are provided on one side of the variable diameter sleeve 2, and multiple friction strips 16 are slidably connected to the inner surface of the two mounting grooves 8.

[0054] In this embodiment: the mounting groove 8 is opened on one side of the variable diameter sleeve 2 to provide an installation position for the friction strip 16, so that the friction strip 16 can effectively increase the friction force, help stabilize the mounting block 17, and prevent loosening due to vibration or other reasons.

[0055] Please refer to the details. Figure 2 Two mounting blocks 17 are fixedly connected to one side of each of the multiple friction strips 16, and two screws 18 are threaded to one side of each mounting block 17.

[0059] The working principle and usage process of this utility model are as follows: First, insert the machine tool spindle body 1 into the sliding groove 6 and the extrusion groove 7. Then, rotate the machine tool spindle body 1 90 degrees. At this time, the outer surface of the machine tool spindle body 1 and the inner surface of the sliding groove 6 form a cross shape. Under the action of the elastic force of the spring 14, the extrusion seat 11 is pushed to slide outward. Under the action of the force, the two locking blocks 19 are pushed into the two locking grooves 10 respectively, thus completing the installation of the machine tool spindle body 1. When disassembling the machine tool spindle body 1, push the machine tool spindle body 1 to slide inward. At this time, the two locking blocks 19 slide out of the two locking grooves 10 respectively. Then rotate the machine tool spindle body 1 90 degrees. At this time, the outer surface of the machine tool spindle body 1 matches the inner surface of the sliding groove 6, thereby removing the machine tool spindle body 1 from the sliding groove 6 and the extrusion groove 7, thus completing the disassembly of the machine tool spindle body 1 and facilitating the maintenance of the machine tool spindle body 1.
