Description

Technical Field

[0001] The utility model relates to an auxiliary device, in particular to a collet-type locking auxiliary device capable of preventing dry friction. Background Art

[0002] In the field of mechanical processing and manufacturing, collet-type locking devices are widely used in various processing equipment to fix and clamp workpieces. However, traditional collet-type locking devices have some significant defects, which affect product quality and processing efficiency.

[0003] The traditional collet-type locking device does not take the application of bearings into consideration in its structural design, which leads to the following problems:

[0004] When the lock nozzle and the lock nozzle sleeve are fastened, dry friction will occur when the workpiece rotates in the lock nozzle. Because there is no bearing support, the lock nozzle and the workpiece are in direct contact, resulting in increased friction, which not only makes the workpiece surface easily scratched and worn, unable to meet high-quality surface requirements, but also increases the wear of the lock nozzle and shortens its service life;

[0005] Dry friction causes scratches and wear on the workpiece surface, affecting the appearance quality of the product, which is unacceptable for products with high requirements for surface finish;

[0006] Due to dry friction and wear of the lock nozzle, the clamping accuracy and processing accuracy of the traditional collet-type locking device will gradually decrease after long-term use, affecting the overall quality of the processed product. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a collet-type locking auxiliary device which can prevent dry friction, and significantly improve the performance of a traditional collet-type locking device by adding front and rear bearings to a nozzle support bracket.

[0008] The utility model can eliminate the dry friction collet type locking auxiliary device by the following technical solutions, including:

[0009] A nozzle support bracket, wherein a mounting position is provided at the upper end of the nozzle support bracket, and bearings are installed at the front end and the rear end of the mounting position;

[0010] A locking nozzle device, wherein the locking nozzle device is arranged through the mounting position, and the outer side surface of the locking nozzle device contacts the inner ring of the bearing;

[0011] When the processed material passes through the locking nozzle device and the locking nozzle device is installed on the nozzle support bracket, the processed material rotates synchronously with the bearing during the processing rotation process.

[0012] As a preferred technical solution, the lock nozzle device includes a lock nozzle body and a lock nozzle sleeve;

[0013] The lock sleeve is inserted into the bearings arranged at the front end and the rear end of the installation position and is fixed by the lock sleeve nut so that the lock sleeve rotates with the bearings at the front end and the rear end of the installation position.

[0014] As a preferred technical solution, the lock nozzle body is arranged through the lock nozzle sleeve, and the processed material is arranged through the lock nozzle hole of the lock nozzle body; the lock nozzle body is fixed to the lock nozzle sleeve by the lock nozzle locking nut, and the processed raw material is fixed to the lock nozzle body by the lock nozzle locking nut.

[0015] As a preferred technical solution, both ends of the bottom of the nozzle support bracket are provided with supporting feet that play a supporting role.

[0016] The beneficial effects of the utility model are:

[0017] 1. In the utility model, after the lock sleeve is tightened, the lock is tightened with the lock sleeve. At this time, when the product rotates during processing, it rotates synchronously with the bearing, and the product will no longer rotate in the lock to cause scratches on the material surface.

[0018] 2. The utility model lock nozzle eliminates the damage caused by friction, thereby extending its service life. Due to the addition of bearings, the load-bearing accuracy is higher, thereby improving the product processing accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0025] like Figure 1-Figure 2 As shown, the utility model is a collet-type locking auxiliary device that can eliminate dry friction, including a nozzle support bracket 1, a mounting position 3 is provided at the upper end of the nozzle support bracket 1, and bearings 4 are installed at the front end and the rear end of the mounting position 3, so that the entire device can be more stable during operation;

[0026] It also includes a locking nozzle device 2, which is arranged through the mounting position 3, and the outer side of the locking nozzle device 2 is in contact with the inner ring of the bearing 4, which enhances the stability of the device and greatly improves its service life;

[0027] When the processed material 10 passes through the locking nozzle device 2 and the locking nozzle device 2 is installed on the nozzle support bracket 1, the processed material 10 rotates synchronously with the bearing 4 during the processing rotation process.

[0028] The lock device 2 includes a lock body 5 and a lock sleeve 6;

[0029] The locking sleeve 6 is inserted into the bearings 4 arranged at the front end and the rear end of the installation position 3 and fixed by the locking sleeve nut 7 so that the locking sleeve 6 rotates with the bearings 4 at the front end and the rear end of the installation position 3.

[0030] In addition, the lock nozzle body 5 is arranged through the lock nozzle sleeve 6, and the processed material 10 is arranged through the lock nozzle hole of the lock nozzle body 5; the lock nozzle body 5 is fixed to the lock nozzle sleeve 6 through the lock nozzle locking nut 8, and the processed raw material is fixed to the lock nozzle body 5 through the lock nozzle locking nut 8.
