Problems solved by technology

[0004] The L-shaped or T-shaped bayonet on the head of the above self-tightening screw needs to be slotted along the axial direction first, and then the slot is translated laterally. Due to the limitation of space position, the processing is extremely difficult, and small-sized self-tightening screws are almost impossible to machine.
Therefore, the self-tightening screw of this structure not only has low processing efficiency, but also has high production cost, and the quality of the processed L-shaped or T-shaped bayonet is difficult to be guaranteed.
On the other hand, due to the one-piece structure, when part of the structure is damaged, only the entire self-tightening screw can be replaced, resulting in increased use costs, and the head of the self-tightening screw is easily damaged due to long-term stress during work

Embodiment 1

[0041] The self-tightening screw of the drill chuck in this embodiment is set in the through hole 11 in the center of the drill chuck main body 1, and is connected with the main body 1 through threads, and the inner ends of each jaw 4 of the drill chuck are sleeved on the self-tightening screw 5 heads. Such as figure 2 , 3 , 4, 6 and 7, it has a columnar body 7, one end of the body 7 is threaded 71, and the other end has a disc-shaped head platform 72, which is provided on the head platform 72 for The inner end of each jaw 4 of the drill chuck is sleeved on three blocks 8 therebetween, and an L-shaped bayonet 9 for inserting the inner end of the jaw 4 is formed between two adjacent blocks 8 . Such as figure 2 , 3, 5, the above-mentioned three clamping blocks 8 are evenly distributed around the center line of the head platform 72, one side of the clamping block 8 is a plane 81, and the other side has a step 82, and the planes of two adjacent clamping blocks 8 81, the ste...

Embodiment 2

[0049] In this embodiment, the manufacturing method of the drill chuck self-tightening screw includes the following steps:

[0050] a. Body preparation: process a thread 71 at one end of the blank, and process a disc-shaped head platform 72 at the other end;

[0051] b. Block plate preparation: process three blocks 8 with the same shape connected to the blank at one end of the blank, that is, the following Figure 8 The block plate 80 shown is composed of a plate bottom 83 and three blocks 8;

[0052] c. Fixed connection: such as Figure 9 As shown, one end of the block plate 80 having three blocks 8 is fixedly connected to the head platform 72 of the body 7;

[0053] d. Forming: remove the disc bottom 83 of the block disc 80 to obtain the drill chuck self-tightening screw.

[0054] In this embodiment, in the above-mentioned step a and / or step b, the blank is made by straightening the circular wire and cutting it according to the required size. In the above-mentioned step ...

Embodiment 3

[0056] In this embodiment, the block 8 and the head platform 82 are fixedly connected together by adhesive. The rest are the same as those in Embodiment 1 or 2, and will not be repeated herein.

Abstract

The invention provides a drill chuck self-tightening screw and a manufacturing method thereof, belonging to the field of drill chucks. It solves the problems of low processing efficiency, high production cost and easy damage of self-tightening screws of the existing drill chuck. The self-tightening screw of the drill chuck is set in the through hole in the center of the drill chuck main body, and is connected with the main body through threads. The inner ends of each jaw of the drill chuck are sleeved on the head of the self-tightening screw, including a columnar The main body is threaded at one end of the main body, and the other end has a disc-shaped head platform. Three clamping blocks evenly distributed around its center line are fixed on the head platform. The sides of two adjacent clamping blocks and the head The platform forms a bayonet for loading the inner end of the jaws, and its manufacturing method includes the following steps: a. body preparation; b. block disc preparation; c. fastening; d. forming. The self-tightening screw bayonet of the drill chuck can be repaired when it is damaged, and the use cost is low. The manufacturing method has the characteristics of easy processing and manufacturing and high production efficiency.

Description

technical field [0001] The invention relates to the field of drill chucks, in particular to a method for manufacturing self-tightening screws for drill chucks, and products produced by the manufacturing method. Background technique [0002] Bench drills are widely used in mechanical processing. In order to process different workpieces, it is often necessary to replace different drill bits. Drill chuck is a device for easy and quick replacement of drill bits. There are usually two types of existing drill chucks: wrench drill chuck and self-tightening drill chuck. The wrench drill chuck needs to use auxiliary tools when clamping or loosening the drill bit, and the operation is cumbersome. The self-tightening drill chuck overcomes the above problems, and it loads and unloads the drill bit through an elastic sleeve that is circumferentially fixed to the main body of the drill chuck. During operation, it is only necessary to turn the elastic sleeve by hand, and its operation is...
