Description

Technical Field

[0001] This utility model relates to the field of brake block processing technology, specifically a fixture for machining arc brake blocks in groups on a vertical lathe. Background Technology

[0002] As the core component of the electric furnace electrode brake device, the machining accuracy of the inner arc surface of the brake block directly determines the contact gap with the electrode post, thus affecting the braking sensitivity and service life of the electrode brake. Traditional machining processes typically employ a single-piece machining method, where each brake block is clamped and its inner arc surface is individually machined on a vertical lathe. However, this process has the following significant drawbacks:

[0003] 1. Coaxiality is difficult to guarantee: Due to the need for repeated disassembly and repositioning of the brake blocks during single-piece processing, the cumulative error leads to a large deviation in the coaxiality of the inner arc surfaces of the same group of brake blocks (4 blocks). After assembly, uneven gaps are easily generated, which reduces the braking performance of the electrode brake.

[0004] 2. Low processing efficiency: Single-piece processing requires multiple clamping, tool setting and adjustment, resulting in a long processing cycle and difficulty in meeting the needs of mass production.

[0005] 3. Insufficient adjustment flexibility: Traditional fixtures lack synchronous adjustment function. When processing different specifications of gate blocks, each clamping position needs to be manually calibrated one by one, which is cumbersome and prone to human error.

[0006] 4. High labor intensity: Operators need to frequently perform clamping, positioning and measurement, which is not only time-consuming and labor-intensive, but also increases the risk of human error. Utility Model Content

[0007] The purpose of this invention is to provide a fixture for machining arc-shaped brake blocks on a vertical lathe, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a fixture for machining arc brake blocks in groups on a vertical lathe, comprising a synchronous adjustment mechanism disposed on the worktable of the vertical lathe, the synchronous adjustment mechanism comprising a drive assembly disposed on the worktable of the vertical lathe, four slide rails equidistantly arranged along the circumference of the worktable of the vertical lathe, and clamping seats slidably disposed on the slide rails; the drive assembly is connected to the clamping seats via a connecting rod, and is used to drive the four clamping seats to move synchronously.

[0009] Furthermore, the drive assembly includes a motor mounted on the center of the vertical lathe worktable via a motor mount and a rotating block rotatably connected to the upper part of the motor mount.

[0010] Furthermore, the clamping seat includes a slider that slides with the slide rail and an inverted T-shaped clamp that is detachably connected to the slider; one end of the connecting rod is rotatably connected to the slider, and the other end of the connecting rod is rotatably connected to the rotating block.

[0011] Furthermore, the vertical lathe workbench is provided with scale lines.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Ensure the coaxiality of the inner arc surface: By setting a synchronous adjustment mechanism on the vertical lathe worktable, the inner arc surface of a group (4) of brake blocks can be milled simultaneously, which effectively ensures the coaxiality of the inner arc surface of a group of brake blocks, improves the assembly quality of the brake blocks, and thus improves the service life and braking sensitivity of the electrode brake.

[0014] 2. Improved processing efficiency: Compared with the traditional single-piece processing method, this fixture can realize group processing, and multiple gate blocks can be processed in one clamping, shortening the processing time and improving processing efficiency.

[0015] 3. Enhanced processing convenience: The synchronous adjustment mechanism can adjust the position synchronously, and can be flexibly adjusted according to the different inner arc surface dimensions of the gate block, which improves the convenience of processing and adapts to the processing needs of various specifications of gate blocks.

[0016] 4. Reduced labor intensity: During operation, staff do not need to frequently clamp and adjust individual gate blocks, reducing operation steps and lowering the workload of staff. Attached Figure Description

[0021] Please see Figures 1 to 2 A fixture for milling arc-shaped brake blocks in groups on a vertical lathe, through a synchronous adjustment mechanism mounted on the worktable 1 of the vertical lathe, allows for the simultaneous milling of the inner arc surfaces of a group of four brake blocks. This ensures the coaxiality of the inner arc surfaces of the group of brake blocks and improves machining efficiency. The synchronous adjustment mechanism can also adjust the position synchronously to machine brake blocks with different inner arc surfaces, enhancing ease of machining and reducing the workload of operators.

[0022] Specifically,

[0023] The synchronous adjustment mechanism consists of a drive assembly, slide rails 2, clamping seats, and connecting rods 3. The drive assembly is detachably connected to a motor base 4 in the center of the circular vertical worktable 1 via bolts, consists of a motor 5 mounted on the motor base 4 via screws, and a rotating block 6 rotatably connected to the upper part of the motor base 4 via bearings. Four slide rails 2 are provided and are evenly spaced along the circumference of the vertical worktable 1 (e.g., ...). Figure 1 (As shown). The clamping seat consists of a slider 7 and an inverted T-shaped clamp 8 detachably connected to the slider 7 by bolts. The clamp 8 has threaded holes for connecting the gate block boss. There are four clamping seats in total, and the T-shaped protrusions on the bottom of the slider 7 of the four clamping seats are slidably connected to the four slide rails 2 respectively. There are also four connecting rods 3. One end of the four connecting rods 3 is rotatably connected to the four sliders 7 respectively, and the other end of the four connecting rods 3 is rotatably connected to the four apex corners of the rotating block 6 respectively.

[0024] The vertical lathe worktable 1 has multiple coaxial scale lines 9 with different diameters. The diameter of the scale line 9 is determined according to the different diameters of the inner arc surfaces of the brake blocks to be processed. The motor 5 mentioned above is specifically a stepper motor.

[0025] Working process and principle of this utility model:

[0026] When machining the inner arc surface of the brake block, the four brake block bosses are first fixed to the four fixtures 8 with bolts, so that the machining surfaces of the four brake blocks face the center of the vertical lathe worktable 1. Then, the motor 5 is started, which drives the rotating block 6 to rotate on the motor base 4. Since the rotating block 6 is rotatably connected to one end of the four connecting rods 3, and the other end of the four connecting rods 3 is rotatably connected to the four sliders 7, and the sliders 7 slide in cooperation with the slide rails 2 that are equidistantly arranged around the circumference of the vertical lathe worktable 1, the rotation of the rotating block 6 will drive the four sliders 7 to move synchronously on the four slide rails 2 through the connecting rods 3. With the synchronous movement of the sliders 7, the positions of the four brake blocks will also be adjusted synchronously. The vertical lathe worktable 1 is equipped with multiple coaxial scale lines 9 with different diameters. Before machining, the operator can refer to the scale lines 9 to accurately adjust the position of the brake block according to the diameter of the inner arc surface of the brake block to be machined, ensuring that the brake block is in the appropriate machining position. After adjusting the position of the brake blocks, the vertical lathe tool can then perform milling on the inner arc surface of the group of brake blocks.
