Description

Technical Field

[0001] The invention relates to the field of bearing press-fitting, and in particular to a quick-change pressing structure. Background Art

[0002] At present, general production enterprises mainly rely on employees to install bearings manually, which has a certain impact on the cleanliness of the bearings and has many disadvantages, such as: foreign matter may remain on the bearing, resulting in poor fit with the shaft, wasting time and manpower, insufficient clamping force, which may cause the bearing to fall off, poor assembly quality, and affect subsequent production operations.

[0003] In recent years, my country's manufacturing industry has been continuously transforming and upgrading, and more and more robots have been used to replace ordinary labor. On the other hand, changes in the consumer market require the manufacturing industry to adopt more flexible manufacturing technology. Flexible manufacturing technology is to use robots or tool quick-change devices to manufacture different products on the same assembly line. In the process of changing the model, the existing quick-change fixture uses thread locking to fix the main body, which requires a long time to position and operate when changing the fixture, and it is inevitable that more labor will be invested. Faced with the increasing production tasks year by year, under the existing production conditions, improving production efficiency is the direction of continuous efforts of the technical department. To reduce costs and improve production efficiency in the machining process, it is necessary to start with the most important link of process design and tooling preparation. The existing production mode of mechanical machining is mainly reflected in the backward application of tooling and low efficiency. The workers spend a long time clamping and aligning when processing parts, especially when the tooling is frequently changed for single-piece or small-batch production, most of the time is spent on installing fixtures and aligning. The necessary measure to achieve this goal is to transform and replace the existing fixtures. While using quick-change fixtures on the production line to achieve processing, it reduces the time for frequent fixture replacement and alignment, which plays a very important role in improving the overall production efficiency.

[0005] According to the technical solution provided in the embodiment of the present application, a quick-change clamping structure includes a connecting head, which is configured as a hollow cylinder, and two through holes with the same axis are provided on both sides of the connecting head, the connecting head is connected to the quick-change head through a connecting pin, the quick-change head is connected to the connecting shaft through screws, and the connecting shaft is connected to the clamping head through screws, a plurality of equally spaced vertical slots are provided on the side of the clamping head, and a plurality of movable blocks are provided in the vertical slots, and the movable blocks are clamped on the clamping head through O-rings.

[0006] In the present invention, a connector is provided at the upper end of the quick-change head, and the outer diameter of the connector is the same as the inner diameter of the connector. Two pin holes with the same axis are provided on both sides of the connector, and the through hole provided on the connector is coaxial with the pin hole.

[0007] The upper end of the quick-change head is a connecting head, and the quick-change head and the connecting head are connected with a clearance fit. Two pin holes with the same axis are provided on both sides of the quick-change head. The pin holes are coaxial with the through holes of the connecting head. The connecting pin passes through the through holes and the pin holes to connect the quick-change head and the connecting head.

It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] like Figure 1 As shown, the quick-change clamping structure of the present application is composed of a connecting head 1, a connecting pin 2, a quick-change head 3, a connecting shaft 4, a clamping head 5, a movable block 6, an O-ring 7, a product 8, etc.;

[0021] like Figure 1 , 2 As shown in Figure 3, the upper end of the connector 1 is connected to the press by screws. The connector 1 is set as a hollow cylinder, and two through holes with the same axis are provided on both sides of the connector 1. The connector 1 is connected to the quick-change head 3 through a connecting pin 2. The upper end of the quick-change head 3 is the connector 1. The quick-change head (3) and the connector (1) are clearance-matched with the shaft and the hole. Two pin holes with the same axis are provided on both sides of the quick-change head (3), and the pin holes are coaxial with the through holes of the connector (1).

[0022] The connecting pin 2 passes through the through hole and the pin hole to connect the quick-change head 3 and the connecting head 1. The quick-change head 3 is connected to the connecting shaft 4 by screws, and the connecting shaft 4 is connected to the clamping head 5 by bolts. The side of the clamping head 5 is provided with a plurality of equally spaced vertical slots, and a plurality of movable blocks 6 are arranged in the vertical slots. A circle of clamping grooves 1 are provided at the slots on the side of the clamping head 5, and a clamping groove 2 is provided on the side of the movable block 6 in the same circumferential horizontal direction as the clamping groove, and the clamping grooves 1 and 2 are aligned. The movable block 6 is clamped on the clamping head 5 by an O-ring 7, and the O-ring 7 is clamped in the clamping grooves 1 and 2. The lower end of the movable block 6 is provided with an inclined surface on the outer side, and protrudes from the bottom surface of the clamping head 5.

[0023] When the pressing head 5 picks up the product 8, the movable block 6 has an O-ring, so the movable block 6 and the O-ring cooperate with each other to clamp the product 8, ensuring that the product 8 is more stable before pressing.

[0024] In summary, the present invention realizes the function of picking up and clamping the workpiece. The movable block 6 reserves a certain amount of movable space.
