Description

Technical Field

[0001] The utility model relates to an upper disc brake device for a double-needle integrated machine. Background Art

[0002] During the operation of the upper disc of the double-needle integrated machine, a certain centrifugal force is generated by the rotation of the upper disc, and the rotation accuracy of the upper disc does not meet the standard and needs to be improved. On this basis, the applicant proposed further improvements and designed a brake device for the upper disc of the double-needle integrated machine to assist the upper disc to stop steadily and solve the problem of inevitable instability during rotation due to the heavy upper disc, so as to meet the needs of the existing market. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a double-needle integrated machine upper disc brake device with a simple overall structure, which can reduce the influence of centrifugal force when the upper disc rotates, thereby achieving the purpose of precise rotation.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A double-needle integrated machine upper disc brake device is arranged on a frame, and is characterized in that it comprises an upper brake disc located on the upper disc, an upper brake disc bracket fixed on the frame, two upper disc brake pad seats fixed on the front end of the upper brake disc bracket, and an installation space is formed between the two upper disc brake pad seats;

[0006] Installing upper disc brake pads on both side walls of the installation space respectively;

[0007] Also included is a control mechanism for controlling the movement of one of the upper disc brake pads.

[0008] The utility model is further optimized, wherein the control mechanism comprises a cylinder, guide shafts are respectively provided at both ends of the output end of the cylinder, one end of the connecting rod of the guide shaft passes through the upper disc brake pad seat and is fixedly connected with the upper disc brake pad; when the cylinder is operating, the movement of the upper disc brake pad is controlled to be tightly attached to the upper brake disc to form a brake.

[0009] As a further preferred embodiment of the utility model, one of the upper disc brake pad seats forms a through hole for a connecting rod of the guide shaft to pass through.

[0010] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0011] The upper disc brake device of the utility model is designed because it is necessary to reduce the influence of centrifugal force when the upper disc rotating device rotates. When it is not necessary to work, the brake disc and the brake pad are not in close contact, and the cylinder is in a state of no air intake. When the upper disc starts to rotate, the cylinder starts to take in air, and the cylinder piston is pushed in, so that the brake pad and the brake disc are in close contact to generate friction, so that the influence of centrifugal force is reduced, thereby achieving the purpose of precise rotation.

They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention.

[0013] In the attached picture:

[0014] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0015] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] like Figure 1 As shown, the utility model discloses a double-needle integrated machine upper disc brake device, which is arranged on a frame 1, and is characterized in that it comprises an upper brake disc 3 located on an upper disc 2, and an upper brake disc bracket 4 fixed on the frame 1, and two upper disc brake pad seats 5 fixed on the front end of the upper brake disc bracket 4, and an installation space is formed between the two upper disc brake pad seats 5;

[0017] The upper disc brake pads 6 are respectively installed on the two side walls of the installation space;

[0018] It also includes a control mechanism for controlling the movement of one of the upper brake pads 6, the control mechanism includes a cylinder 7, and guide shafts 8 are respectively provided at both ends of the output end of the cylinder 7. One end of the connecting rod 9 of the guide shaft 8 passes through the upper brake pad seat 5 and is fixedly connected to the upper brake pad 6; when the cylinder 7 is in operation, the movement of the upper brake pad 6 is controlled to be tightly attached to the upper brake disc 3 to form a brake.

[0019] In the present invention, one of the upper plate brake pad seats 5 is formed with a through hole 10 for the connecting rod 9 of the guide shaft 8 to pass through.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
