Description

Technical Field

[0001] This utility model belongs to the field of drilling equipment technology, and in particular relates to a drilling equipment for the production of sliding bearings. Background Technology

[0002] Sliding bearings are bearings that operate under sliding friction. They are characterized by smooth operation, reliability, and no noise. In order to ensure that the lubricating oil can fully reach the contact surface of the bearing and form a stable oil film, drilling equipment is often used to open holes in the sliding bearing.

[0003] Currently, in practical applications of existing drilling equipment, it has been found that the bearings being processed are of a ring structure, and the outer clamps are often fixed to the two sides of the bearing. This causes the bearing to easily deflect during drilling operations. In mild cases, the hole opening position will be deviated, and in severe cases, the hole opening will fail, damaging the tool and the workpiece.

[0004] To address the aforementioned problems, this application proposes a drilling device for the production of sliding bearings. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for the production of sliding bearings, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a drilling device for producing sliding bearings, comprising: a drilling machine and a drill bit; the drilling machine has a fixed base inside, through which the workpiece is placed by a support on its inner side, and the inner side of the support has a positioning pin for positioning the bearing to be drilled; the drilling machine also has a slide block inside, used for transferring the bearing after drilling; the inner side of the support has a support seat, which, together with the lower top seat below it, forms a tight clamping and fixing on the upper and lower inner surfaces of the bearing, and at the same time provides support for the upper inner surface of the bearing to ensure the structural stability around the drilled position.

[0008] Furthermore, the inner side of the fixed seat is provided with a side seat, and the support is moved back and forth by an electric telescopic device on one side to move the bearing out of the working area. The inner side of the side seat is provided with a baffle that abuts against the bearing and causes it to automatically fall into the slide.

[0009] Furthermore, the lower top seat is provided with side plates on both sides to increase the contact range with the bearing, and the blocking block at its lower end increases the frictional resistance to ensure the stable installation of the bearing.

[0010] Furthermore, a limiting groove is provided inside the upper end of the lower top seat for installing an electric expansion joint, and the electric expansion joint is arranged in the same way on the lower end of the support seat and the inner side of the side seat.

[0011] Furthermore, the upper end of the support base is provided with a storage groove for storing debris and impurities.

[0012] Furthermore, the interior of the limiting groove is provided with a connecting plate that is fixedly connected to the upper end of the adjacent side plate.

[0013] Furthermore, the lower end of the connecting plate is provided with a telescopic connector that mates with the ground of the limiting groove.

[0014] This utility model has the following beneficial effects:

[0015] This utility model forms a built-in clamping mechanism through the cooperation of the support base and the lower top base, which replaces the traditional side clamping method. It provides support for the upper and lower inner sides of the bearing, preventing the bearing from deflecting, and also provides support around the drilling position to ensure the structural stability of the bearing.

[0016] In addition, the storage slots allow for the immediate collection of debris, facilitating subsequent centralized processing.

[0017] This invention allows for convenient fixing of the bearing through the cooperation of the support base, the lower top base, and the blocking block. During pre-clamping, the bearing can be easily moved to adjust its direction. At the same time, the positioning pin allows for intuitive observation of the position of the hole to be drilled, ensuring the drilling accuracy of the bearing and improving the production quality of the workpiece.

[0028] Please see Figure 1-4 As shown, this utility model is a drilling equipment for producing sliding bearings, including: a drilling machine 1 and a drill bit 2; the drilling machine 1 is provided with a fixed seat 4 inside, and the workpiece is placed by the support 3 on its inner side. The support 3 is provided with a positioning pin 12 on its inner side to locate the hole to be drilled in the bearing.

[0029] The drilling machine 1 is also equipped with a slide 5 inside, which is used to transfer the bearing after the hole is drilled;

[0030] The support 3 has a support seat 8 on its inner side, which, together with the lower top seat 9 below it, forms a tight and fixed upper and lower surfaces of the bearing. At the same time, it provides support for the upper inner surface of the bearing to ensure the stability of the structure around the opening position. The upper end of the support seat 8 has a storage groove 15 for storing debris and impurities.

[0031] This embodiment provides a stable drilling device. It uses the upper and lower support seats 8 and the lower top seat 9 to replace the traditional external clamping structure, thereby achieving the effect of supporting the bearing and ensuring its structural stability. This facilitates drilling operations. In addition, it can automatically collect the debris generated during drilling, which is convenient for subsequent centralized processing and use.

[0032] The fixed seat 4 has a side seat 6 on its inner side. The support 3 is moved back and forth by the electric telescopic device 13 on one side to move the bearing out of the working area. The side seat 6 has a baffle 7 on its inner side to hold the bearing and make it automatically fall into the slide 5, which facilitates the installation and removal of the sliding bearing.

[0033] The lower top seat 9 has side plates 10 on both sides to increase the contact range with the bearing. The blocking block 11 at its lower end increases the frictional resistance to ensure the stable installation of the bearing and prevent the bearing from deflecting during drilling.

[0034] Among them, the upper end of the lower top seat 9 has a limiting groove 14 for installing the electric expansion joint 13. The electric expansion joint 13 is arranged in the same way at the lower end of the support seat 8 and the inner side of the side seat 6.

[0035] The limiting groove 14 has a connecting plate 16 inside which is fixedly connected to the upper end of the adjacent side plate 10.

[0036] The lower end of the connecting plate 16 is provided with a telescopic connector 17 that connects to the ground of the limiting groove 14, which is used to automatically adapt to the tight state of the blocking block 11.

[0037] It is understandable that this utility model can provide internal support for the bearing to ensure its structural stability, facilitate drilling operations, and automatically collect the debris generated during drilling for convenient subsequent centralized processing and use.

[0038] A specific application of the operation process of this embodiment is as follows: In use, firstly, the bearing is hung on the outside of the support base 8 and moved to the positioning pin 12 to position the hole to be drilled. Then, the electric telescopic device 13 drives the lower top seat 9 to abut against the lower end of the bearing to form a limit. At the same time, the blocking block 11 abuts against the bottom two sides of the inner side of the bearing to increase the limit range and frictional resistance, ensuring the stable installation of the bearing. At this time, the support base 8 provides support around the opening position on the inner upper surface of the bearing, ensuring the structural stability of the bearing during drilling. Finally, the baffle 7 blocks the bearing brought out by the support 3, causing it to automatically slide into the interior of the slide block 5 for transfer, which is convenient for subsequent price processing.
