Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic brake processing equipment, and in particular to a milling processing equipment for the end face of an electromagnetic brake core. Background Technology

[0002] In the critical components of elevators, especially in the machining of the end faces of components such as the electromagnetic brake core on the traction machine, it is necessary to mill the end faces of both ends of the core so that the height of the top surface of the end face is lower than the height of the middle plane of the core. Usually, it needs to be machined to be lower than the middle plane of the core.

[0003] Patent CN212169108U discloses a milling device for the end face of an electromagnetic brake core. The device includes a milling cutter with a milling tool and a fixture base. The fixture base has multiple fixing holes for the electromagnetic brake cores to be milled. After being fixedly installed and connected, the multiple electromagnetic brake cores are arranged in a row on the fixture base with the milled surfaces facing upwards. The long sides of each electromagnetic brake core are parallel to each other and arranged in a row. The two end faces are distributed along the running direction of the fixture base, forming two rows of milled end faces. A milling tool for milling the end faces is correspondingly placed above each row of milled end faces.

[0004] The aforementioned patents still have the following technical defects: the equipment can only continuously process one row of workpieces in a single operation, and cannot achieve continuous uninterrupted material feeding. Furthermore, after processing, the workpieces need to be removed one by one before the next batch of workpieces can be placed and processed. Its work efficiency still needs to be improved.

[0024] Example 1

[0025] like Figures 1-3 As shown in the figure, the electromagnetic brake core end face milling equipment proposed in this embodiment includes a frame 1, a protective cover 7, an upper clamping assembly, two sets of milling mechanisms, and multiple placement seats 5.

[0026] A transmission belt 2 is mounted on the frame 1. A power assembly for driving the transmission belt 2 is also mounted on the frame 1. The power assembly includes a servo motor 3 and two transmission rollers 4. The two transmission rollers 4 are rotatably mounted at both ends of the frame 1. The transmission belt 2 is sleeved on the two transmission rollers 4. The servo motor 3 is mounted on the frame 1 and its output shaft is connected to the rotating shaft of the transmission rollers 4.

[0027] Multiple placement seats 5 are arranged in an array along the path direction of the transmission belt 2. Placement slots 501 are provided on the placement seats 5. A first support 61 is connected between the placement seat 5 and the outer surface of the transmission belt 2. A second support 62 is connected to both ends of the bottom of the placement seat 5. It should be noted that the second support 62 is not connected to the transmission belt 2, but only serves to support the placement seat 5.

[0028] The protective cover 7 is installed on the upper end of the frame 1. The protective cover 7 has openings at both ends and the bottom. A cloth curtain 10 is installed at both ends of the protective cover 7. The cloth curtain 10 can prevent water stains and debris from splashing out.

[0029] The protective cover 7 is equipped with an equipment box 9; both sets of milling mechanisms are installed above the transmission belt 2. The milling mechanism includes a drive motor, a transmission shaft and a milling cutter 14. The drive motor is installed inside the equipment box 9, and the output shaft of the drive motor is connected to the transmission shaft. The transmission shaft moves through the inside and outside of the equipment box 9. The milling cutter 14 is installed at the bottom of the transmission shaft. Furthermore, an electric push rod for driving the drive motor to rise and fall is installed inside the equipment box 9. The rising and falling height of the milling cutter 14 can be adjusted by the electric push rod, thereby adjusting the cutting depth of the workpiece.

[0030] The upper clamping assembly includes a mounting frame 13 installed inside the protective cover 7 and multiple upper support rollers 12 rotatably mounted side by side on the mounting frame 13. When the workpiece moves to the position of the upper support rollers 12, the bottom end of the upper support rollers 12 contacts the workpiece, thereby limiting the movement of the workpiece.

[0031] A nozzle 15 is installed at an angle at the bottom of the equipment box 9. The spraying end of the nozzle 15 is angled toward the conveying start end of the adjacent transmission belt 2. A water source is connected to the water pipe connected to the nozzle 15. Water is sprayed out through the nozzle 15 onto the milling cutter 14 and the workpiece, which serves two purposes: cooling and rinsing off waste materials.

[0032] A water storage tank 8 is provided below the protective cover 7. The water storage tank 8 is installed on the frame 1 and is used to receive the wastewater after cooling. It should be added that, in order to realize the recycling of wastewater, a filter screen is installed on the upper inner side of the water storage tank 8 to intercept the waste chips generated by cutting.

[0033] Specifically, the workpiece (electromagnetic brake core) is placed on the placement seat 5. The placement groove 501 enables horizontal positioning of the workpiece. The power assembly drives the transmission belt 2, which in turn moves the workpiece to the inside of the protective cover 7. Two milling mechanisms work simultaneously to achieve synchronous cutting of both ends of the moving workpiece. Before cutting, multiple upper support rollers 12 press against the surface of the workpiece to prevent it from shifting and further limit its movement. After the cutting operation is completed, the workpiece is removed from the inside of the protective cover 7. When the workpiece moves to the end of the transmission belt 2 and begins to flip downwards, it falls off, achieving automatic unloading.

[0034] Example 2

[0035] like Figure 2 As shown in the figure, the electromagnetic brake core end face milling equipment proposed in this embodiment has the following advantages over the first embodiment. In this embodiment, multiple lower support rollers 11 are arranged side by side on the inner side of the transmission belt 2. The multiple lower support rollers 11 are rotatably installed inside the protective cover 7, and the lower support rollers 11 are in contact with the upper end of the inner side of the transmission belt 2. The multiple lower support rollers 11 installed can support the upper end of the transmission belt 2, which can prevent the workpiece from moving downward during the cutting process and ensure the processing quality.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
