Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a four-axis turntable with dual brakes. Background Technology

[0002] Existing four-axis rotary tables generally use a single rear brake structure, and their braking efficiency is limited by the braking force at a single point. Especially in heavy-load or high-speed rotation scenarios, there are problems such as braking delay and insufficient braking force. Traditional solutions require significant modifications to the overall rotary table structure and the addition of extra hydraulic circuits, resulting in increased costs and installation complexity. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a four-axis turntable with dual brakes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A four-axis rotary table dual-brake structure includes a housing, in which a rotary table bearing is connected by screws, a turret is connected to one side of the rotary table bearing by screws, a rear brake pad is provided on one side of the turret, a rear brake ring is sleeved on the outer wall of the turret on the side of the rear brake pad, and a turnbuckle bearing is sleeved on the tail end of the turret on the side of the rear brake ring, and a rear brake shell is sleeved on the outside of the turnbuckle bearing.

[0006] A front brake ring is located outside the turntable bearing inside the housing. One side of the front brake pad passes through the turntable bearing and is connected to the housing by screws. Both the front brake housing and the rear brake housing are connected to the housing by screws.

[0007] In addition, a preferred structure is that a dial is provided on the front brake housing side of the housing, and the dial is connected to the turntable bearing by screws.

[0008] Furthermore, in a preferred configuration, a first cavity is provided within the housing at the locations of the rear brake pads, rear brake rings, turnbuckle bearings, and rear brake housings.

[0009] Furthermore, in a preferred configuration, a second cavity is provided within the housing at the locations of the turntable bearing, the front brake ring, the front brake pad, and the front brake housing.

[0010] Furthermore, in a preferred configuration, a hydraulic input port is provided at one end of the turret inside the housing, and flow channels are provided inside the housing between the first cavity and the hydraulic input port, and between the second cavity and the hydraulic input port.

[0011] The beneficial effects of this utility model are as follows:

[0012] In this invention, the front brake assembly and the rear brake assembly are symmetrically arranged on both sides of the turret. With the help of the hydraulic input port and the flow channel, the hydraulic oil entering the housing can be distributed to ensure that the hydraulic oil is injected into the front and rear brake cylinders synchronously. The front brake ring and the rear brake ring synchronously squeeze the corresponding front brake pad and the rear brake pad. The braking force is distributed bidirectionally along the axial direction of the turntable, which greatly improves the braking torque. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-1 A four-axis turntable dual-brake structure includes a housing 1, a turntable bearing 7 connected to the housing 1 by screws, a turret 6 connected to one side of the turntable bearing 7 by screws, a rear brake pad 5 provided on one side of the turret 6, a rear brake ring 4 sleeved on the outer wall of the turret 6 on the side of the rear brake pad 5, and a turntable bearing 2 sleeved on the tail end of the turret 6 on the side of the rear brake ring 4, and a rear brake shell 3 sleeved on the outside of the turntable bearing 2.

[0017] Inside the housing 1, outside the turntable bearing 7, is a front brake ring 8. One side of the front brake pad 9 passes through the turntable bearing 7 and is connected to the housing 1 by screws. The front brake housing 10 and the rear brake housing 3 are both connected to the housing 1 by screws.

[0018] Furthermore, the turntable bearing 7 and the turret 6 are fixed together by screws.

[0019] Furthermore, a dial 11 is provided on the side of the front brake housing 10 of the housing 1, and the dial 11 is connected to the turntable bearing 7 by screws.

[0020] Meanwhile, a first cavity is provided inside the housing 1 at the locations of the rear brake pad 5, rear brake ring 4, turnbuckle bearing 2, and rear brake housing 3.

[0021] Meanwhile, a second cavity is provided inside the housing 1 at the turntable bearing 7, front brake ring 8, front brake pad 9, and front brake housing 10.

[0022] Furthermore, a hydraulic input port 12 is provided at one end of the turret 6 inside the housing 1, and flow channels are provided between the first cavity and the hydraulic input port 12 and between the second cavity and the hydraulic input port 12 inside the housing 1. It is worth noting that the flow channel in the first cavity is located above the rear brake ring 4 and the rear brake housing 3, and the flow channel in the second cavity is located above the side of the front brake ring 8 away from the front brake housing 10.

[0023] In this embodiment, hydraulic oil enters through the hydraulic input port 12 and flows into the first cavity and the second cavity along the flow channel, pushing the corresponding rear brake ring 4 and front brake ring 8. The front brake ring 8 is pressed against the front brake pad 9 to adhere to the front brake housing 10, and the rear brake ring 4 is pressed against the rear brake pad 5 to adhere to the housing 1. The braking effect is achieved through friction.

[0024] It is worth noting that the rear brake assembly consists of the rear brake pad 5, the rear brake ring 4, the turntable bearing 2, and the rear brake housing 3, while the front brake assembly consists of the turntable bearing 7, the front brake ring 8, the front brake pad 9, and the front brake housing 10.

[0025] In this invention, the front brake assembly and the rear brake assembly are symmetrically arranged on both sides of the turret 6. With the help of the hydraulic input port 12 and the flow channel, the hydraulic oil entering the housing 1 can be distributed to ensure that the hydraulic oil is injected into the front and rear brake cylinders simultaneously. The front brake ring 8 and the rear brake ring 4 simultaneously squeeze the corresponding front brake pad 9 and rear brake pad 5. The braking force is distributed bidirectionally along the axial direction of the turntable, which greatly improves the braking torque.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
