Abstract
Description
Technical Field
[0001] This utility model belongs to the field of elevator processing technology, specifically relating to a welding positioning fixture for an elevator buffer seat. Background Technology
[0002] The elevator buffer seat is the final safety device in an elevator system, and its quality directly affects the overall performance of the elevator. During the production of the elevator buffer seat, two buffer plates need to be welded to both ends of a cylindrical buffer component. Current processes typically involve first using welding fixtures to fix the workpiece, followed by welding with a welding robot. However, existing welding fixtures require manual adjustment of the two buffer plates and the cylindrical buffer component to achieve proper clamping and fixation. Due to the limitations of manual operation, welding positioning is often inaccurate, and weld points are prone to deviating from the design standard position. This not only damages the product's geometry but may also weaken its mechanical properties and load-bearing capacity.
[0003] The structure of the buffer seat mainly serves two functions: first, to fix the buffer, ensuring that the buffer remains stable during elevator operation and preventing it from being affected by shaking or displacement; second, to withstand pressure, the buffer seat can withstand the weight of the elevator and the pressure generated during the buffering process, thereby ensuring that the buffer can effectively play its buffering role, converting part of the impact force into the deformation energy of the spring and the compression energy of the hydraulic buffer, achieving deceleration and stopping, and protecting the safety of passengers and elevator equipment.
[0004] Therefore, ensuring the accuracy of the welded dimensions of the buffer seat to ensure uniform stress and avoid eccentric stress is particularly important. At the same time, improving the welding positioning process can not only increase work efficiency and reduce labor costs, but also accelerate the welding positioning speed. Welding positioning fixtures play a crucial role in the welding process; they not only ensure the important dimensions of the product and improve processing quality, but also enhance work efficiency, making them essential for production and processing. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide a welding positioning fixture that provides rapid positioning of the elevator buffer seat in three directions during the welding process, thereby improving the welding accuracy.
[0006] This utility model is achieved through the following technical solution:
[0007] A welding positioning fixture for an elevator buffer seat includes a base and a first direction positioning device, a second direction positioning device, and a height positioning device disposed on the base; the first direction positioning device and the second direction positioning device are perpendicular to each other and form a processing area enclosed on two sides; the height positioning device is located within the processing area.
[0008] In the welding positioning fixture for elevator buffer seats provided by this utility model, a first-direction positioning device and a second-direction positioning device are disposed on the base for positioning the elevator buffer seat to be processed in the first and second directions. The first-direction positioning device and the second-direction positioning device are perpendicular to each other and form a processing area with two sides enclosed. The height positioning device is located within the processing area and is used to position the processing height of the elevator buffer seat to be processed within the processing area. By forming a processing area with two sides enclosed by the first-direction positioning device and the second-direction positioning device, while limiting the elevator buffer seat in the first, second, and height directions, a certain amount of space is left for processing elevator buffer seats of different specifications. The welding positioning fixture of this utility model provides rapid positioning of the elevator buffer seat in three directions during the welding process, improving the welding processing accuracy.
[0009] Furthermore, the first directional positioning device includes a first directional baffle for abutting against the first buffer plate of the elevator buffer seat. The first directional baffle extends along a first direction and is vertically disposed on the base. The second directional positioning device includes a second directional baffle for abutting against the second buffer plate of the elevator buffer seat. The second directional baffle extends along a second direction and is vertically disposed on the base. The first directional baffle and the second directional baffle are perpendicular to each other and form the processing area enclosed on two sides. The first directional baffle extends along the first direction and is vertically disposed on the base, and the second directional baffle extends along the second direction and is vertically disposed on the base. The first baffle and the second baffle form the processing area enclosed on two sides and can be used to position the first buffer plate and the second buffer plate of the elevator buffer seat.
[0010] Furthermore, the height positioning device includes at least one lifting member for abutting against the cylinder of the elevator buffer seat. The lifting member is vertically disposed on the base plate and located within the processing area. The lifting member is vertically disposed on the base plate and located within the processing area, and the cylinder of the elevator buffer seat abuts against the lifting member in the vertical direction, for positioning the processing height of the elevator buffer seat to be processed.
[0011] Furthermore, the lifting component has a vertically upward-facing arc-shaped support groove extending along a first direction. This vertically upward-facing arc-shaped support groove is designed to conform to the cylindrical shape of the elevator buffer seat, preventing movement of the elevator buffer seat while positioning the processing height.
[0012] Furthermore, the number of the lifting components is at least two, and both of the lifting components are located within the processing area. The at least two lifting components are aligned in a straight line and spaced apart along a first direction. This alignment of the lifting components in a straight line and spaced apart along the first direction provides support to the cylinder of the elevator buffer seat at multiple locations, preventing movement.
[0013] Furthermore, a positioning element is provided on the side of the first directional baffle facing the height positioning device. The positioning element protrudes from the first directional baffle and is used to engage with the first buffer plate of the elevator buffer seat to be processed, thereby positioning the first buffer plate and preventing the first buffer plate from moving.
[0014] Furthermore, the first directional baffle is provided with a central machining area corresponding to the center position of the first buffer plate of the elevator buffer seat; the center position of the arc-shaped support groove corresponds to the center position of the central machining area. With the center position of the arc-shaped support groove corresponding to the center position of the central machining area, during processing, the first buffer plate abuts against the first directional baffle, and the cylinder abuts against the supporting component, directly aligning the first buffer plate of the elevator buffer seat with the cylinder, thus improving machining accuracy.
[0015] Furthermore, the number of positioning elements is at least two, and the at least two positioning elements are symmetrically distributed around the central processing area. The at least two positioning elements symmetrically distributed around the central processing area are used to engage and position with the edge processing area of the first buffer plate, preventing the first buffer plate from moving during processing.

Please refer to [link / reference]. Figure 1-3 In the welding positioning fixture for elevator buffer seats provided in this embodiment, a first-direction positioning device 2 and a second-direction positioning device 3 are disposed on a base 1 for positioning the elevator buffer seat 5 to be processed in the first and second directions. The first-direction positioning device 2 and the second-direction positioning device 3 are perpendicular to each other and form a processing area with two sides enclosed. A height positioning device 4 is located within the processing area for positioning the processing height of the elevator buffer seat 5 to be processed within the processing area. By forming a processing area with two sides enclosed by the first-direction positioning device 2 and the second-direction positioning device 3, while limiting the elevator buffer seat 5 in the first, second, and height directions, a certain amount of space is left for processing elevator buffer seats 5 with different specifications. The welding positioning fixture of this embodiment provides rapid positioning of the elevator buffer seat 5 in three directions during the welding process, improving the welding processing accuracy.
[0026] In this embodiment, the first direction positioning device 2 includes a first direction baffle 21 for abutting against the first buffer plate 51 of the elevator buffer seat 5. The first direction baffle 21 extends along a first direction and is vertically disposed on the base 1. The second direction positioning device 3 includes a second direction baffle 31 for abutting against the second buffer plate 52 of the elevator buffer seat 5.

[0029] In this embodiment, the number of lifting members 41 is at least two, and both lifting members 41 are located within the processing area.

Then, the second buffer plate 52 abuts against the other end of the buffer member 53, and at the same time, the second buffer plate 52 abuts against the second direction baffle 31 to achieve the positioning of the second buffer plate 52. At this time, the second buffer plate 52 can be welded and fixed to the other end of the buffer member 53.
