Guide sleeves are made of a variety of materials, including steel, plastic, and rubber.

[0003] Guide sleeves are also widely used in the engineering field to ensure accurate alignment and repeatability between various components, and improve the work efficiency and production efficiency of engineers. The application of guide sleeves has many advantages, such as ensuring the accuracy of the position and angle of mechanical parts, avoiding offset or slight misalignment between mechanical parts, simple installation, reusable, and can reduce friction between mechanical parts, thereby reducing the effects of wear and tear.

[0004] At present, in the press-fitting production process of the guide sleeve, it is necessary to press-fit the guide sleeve to a specific component. In this process, the traditional press-fitting method adopts manual press-fitting, that is, the guide sleeve is placed on the mounting part and then directly press-fitted. The worker needs to pay attention to aligning it when placing it. After placing it, any interference before press-fitting may cause the bushing to be skewed. After that, press-fitting is performed. This operation process is cumbersome, the work efficiency is low, and the qualified rate of finished product press-fitting is poor. Therefore, a press-fitting structure for a guide sleeve is urgently needed. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A press-fitting structure of a guide sleeve comprises a body 1, a cylinder 2 is arranged on the upper part of the body 1, a press-fitting cylinder 21 is installed on the telescopic rod of the cylinder 2, a pair of press-fitting clamping blocks 5 are arranged below the press-fitting cylinder 21, the press-fitting clamping blocks 5 are limitedly movable and installed in a transverse adjustment groove 8 provided on the body 1, a limit plate 4 is arranged in the middle part of the body 1, and a bottom limit plate 3 is arranged at the bottom of the body 1;

[0025] Furthermore, an adjustment handle 6 is rotatably installed on one side of the body 1, one end of the adjustment handle 6 is connected to a double-headed reverse-threaded screw 61, and one end of the double-headed reverse-threaded screw 61 is rotatably installed on one side of the inner wall of the body 1, wherein a pair of press-fit clamps 5 are screwed on the upper limit position of the double-headed reverse-threaded screw 61.

[0026] A vertical adjustment slot 7 is provided in the middle of the machine body 1, and a limit plate 4 is horizontally arranged on the vertical adjustment slot 7. One side of the limit plate 4 is installed in the vertical adjustment slot 7 by a fastening block 41. The vertical adjustment slot 7 can realize the free adjustment of the limit plate 4, so as to adapt to different workpieces.

[0027] Moreover, a circular slot is provided in the middle of the limiting plate 4. The setting of the limiting plate 4 can effectively increase the stability during press-fitting, avoid the misalignment of the press-fitted parts, and avoid the operation of repeated manual alignment.

[0028] In addition, a pair of press-fitting clamps 5 are installed in the transverse adjustment groove 8 for limited movement. The press-fitting clamps 5 are mirror-imaged to each other, and one side of the press-fitting clamps 5 extends into the interior of the machine body 1 and is connected to an adjustment block 51 .

[0029] At the same time, one end of each adjusting block 51 is screwed to the double-headed reverse-threaded screw 61 , and one end of the adjusting block 51 is installed in the transverse adjusting groove 8 for limited movement.

[0030] Furthermore, one side of the press-fitting clamp block 5 is connected to an arc plate 52 through a telescopic column 9, the arc plate 52 is M-shaped, and a rubber pad 10 is arranged in the middle thereof. The rubber pad 10 can increase the clamping stability of the guide sleeve.

[0031] Furthermore, a through hole is provided at one end of the press-fitting clamp 5, and a telescopic column 9 is installed in the through hole for limited movement. One end of the telescopic column 9 is connected to the arc plate 52, and the other end extends into the press-fitting clamp 5 and is connected to the spring 11 through the baffle. The spring 11 can ensure the stability of the guide sleeve fixation and can adapt to guide sleeves of different sizes.

[0032] In this embodiment, the workpiece is placed on the bottom limit plate 3 set in the body 1. The limit plate 3 is composed of two limit blocks, which can preliminarily fix the bottom of the workpiece. At the same time, the limit plate 4 is set in the middle of the body 1. The limit plate 4 can still be freely adjusted and moved through the vertical adjustment slot 7, so as to adapt the workpiece.

[0033] At the same time, the processed guide sleeve is installed in the press-fitting clamp 5. The arc plate 52 arranged on the press-fitting clamp 5 can make the installation process of the guide sleeve easier and more convenient due to its M-shaped design. The guide sleeve can be clamped more stably through the arrangement of the telescopic column 9 and the spring 11, and the rubber pad 10 arranged in the arc plate 52 can increase the stability of the guide sleeve. When the guide sleeve is installed on the press-fitting clamp 5, the arc plates 52 on both sides are squeezed and telescoped in the press-fitting clamp 5 through the telescopic column 9.

[0034] During its use, the adjustment handle 6 can be rotated to rotate the internal double-headed reverse screw 61, thereby realizing the function of adjusting the two press-fitting clamps 5. Compared with manual operation, it can not only align and load the materials faster, but also make the press-fitting process simple and convenient.

[0035] Among them, it is worth noting that the threads of the two ends of the double-headed reverse-thread screw 61 have opposite rotation directions. According to needs, it is generally set to have one end left-handed and the other end right-handed. This design gives the screw some unique advantages and characteristics during assembly or disassembly, and is suitable for bidirectional adjustment or bidirectional locking.

[0036] In the utility model, the processing guide sleeve is installed in the press-fitting clamp block and fixed by the press-fitting clamp block 5. At the same time, the cylinder 2 arranged on the top cooperates with the setting of the press-fitting tube to realize the press-fitting operation of the workpiece. At the same time, the clamping gap between the press-fitting clamp blocks can be achieved by rotating the adjustment handle 6, which effectively achieves the purpose of replacing manual straightening processing. At the same time, the arc plate arranged on the press-fitting clamp block can be used for faster loading and press-fitting, and the bottom limit plate and bottom limit disk can increase the stability of the press-fitting, further improving its press-fitting efficiency and press-fitting quality.
