Problems solved by technology

[0003] For manufacturers, the supply volume of this product is very large, and the monthly supply volume can reach tens of thousands of pieces. The existing elevator brake pad production method is generally to use the machine tool's own clamp to clamp the brake pad blank, and then drill holes separately. , plane milling and other processes, often processing a brake pad blank requires multiple clamping and machine tool replacement operations, which is time-consuming and laborious. Therefore, it is necessary to have a processing device and processing method that can efficiently and mass-produce elevator brake pads

Embodiment 1

[0070] Refer to attached figure 1 and 2 , a brake pad processing device for an elevator, comprising a bench vise, a first numerically controlled machine tool, a fixture and a second numerically controlled machine tool; On the processing table of the second CNC machine tool; the fixture includes a base 1, a clamping portion 2 and a positioning pin 3; there are multiple clamping portions 2, and gaskets are provided on the base, and the positioning The pin shaft 3 is fixedly connected to the base 1 through a gasket, and there are multiple positioning pin shafts 3; the positioning pin shaft 3 includes a first positioning pin 301, a second positioning pin 302 and an error prevention pin 303; A locating pin 301 and a second locating pin 302 are used to locate the locating pin hole on the elevator brake pad, and the error-preventing pin 302 is used to locate any bolt hole on the side where the bolt hole on the elevator brake pad is collinear with the locating pin hole; The clamping...

Embodiment 2

[0073] Most of the contents of an elevator brake pad processing device in Embodiment 2 are the same as in Embodiment 1, except that the tooling fixture also includes an anti-collision block,

[0074] Such as Figure 6 and Figure 7 As shown in the anti-collision block, the anti-collision block is fixedly connected to the bottom of the pressure block, the anti-collision block is provided with a slot, and the top of the tension rod is provided with a bump, and the tension rod is clamped by the bump. Connected to the slot of the anti-collision block.

[0075] When processing the long side of the elevator brake pad on the side of the tension rod, toggle the tension cylinder switch to retract the tension rod into the cylinder body, and the height of the cylinder body is lower than the height of the gasket. Therefore, when processing the side of the elevator brake pad, The tool will not cut to the first connecting part at the top of the tension rod; when processing the two short s...

Embodiment 3

[0077] A method for processing elevator brake pads by an elevator brake pad processing device;

[0078] The elevator brake pad processing device includes a bench vise, a first numerically controlled machine tool, such as figure 1 Shown fixture and the second CNC machine tool; the bench vise is fixed on the processing table of the first CNC machine tool, and the tooling fixture is fixed on the processing table of the second CNC machine tool; the tooling fixture includes a base 1. The clamping part 2 and the positioning pin shaft 3; the middle part of the base 1 is fixedly connected with a fixing nut 4, and there are four clamping parts 2, and the clamping part 2 is rotatably connected to the base 1, and the positioning The pin shaft 3 is fixedly connected on the base 1, and there are two positioning pin shafts 3; the positioning pin shaft 3 includes a first positioning pin 301, a second positioning pin 302 and an error prevention pin 303; the first positioning pin The second p...

Abstract

The invention relates to the field of elevator production, in particular to an elevator brake pad machining device and a machining method of the elevator brake pad. The machining method comprises thesteps of 1, clamping the elevator brake pad on a table vice with the top surface of the elevator brake pad facing upward, and clamping the two short side surfaces; 2, milling the top surface and two long side surfaces of the elevator brake pad by using a first numerical control machine tool; 3, milling two positioning pin holes of the elevator brake pad by using a first numerical control machine tool by taking the long side surfaces as a machining reference; 4, placing the elevator brake pad on a tooling fixture with the bottom surface of the elevator brake pad facing upward, positioning by using a positioning pin shaft, and pressing two thin wings of the elevator brake pad; 5, milling the bottom surface of the elevator brake pad by using a second numerical control machine tool by taking the top surface of the elevator brake pad as a machining reference; and 6, pressing a pressing block on the bottom surface of the elevator brake pad. The machining device and the machining method are used for mass production of elevator brake pads.

Description

technical field [0001] The invention relates to the field of elevator production, in particular to an elevator brake pad processing device and processing method. Background technique [0002] Elevator brake pads are brake pads that need to be suspended when the elevator ascends and descends. It is a safety part and has high requirements for material hardness and processing accuracy. For example, the patent for invention with the publication number CN108263980A "An Elevator Brake Using a Dual Brake System and Its Braking Method", which discloses a tongue plate used for braking, that is, an elevator brake pad. The surface accuracy of the elevator brake pad is The requirements are high, all the exterior surfaces need to be exposed to light during processing, and the blanking size must be left on each surface. After the top surface is finished, the hole on the top surface should be used as the positioning of the back processing to ensure the position of the entire product. prec...
