[0002] The elevator speed limiter is one of the safety control components in the elevator safety protection system. When the elevator car is overspeeding or even in danger of falling during normal operation, the first protection device, the speed limiter, will work in conjunction with the safety clamp to stop the elevator car. When the elevator speed limiter is in use, it is necessary to install and fix the elevator speed limiter on the mounting base to prevent the elevator speed limiter from sliding during use, which will affect the use of the elevator speed limiter. In the traditional welding work of the speed limiter base, each set of welding requires manual measurement of dimensions and manual positioning of each component. There is no fixed clamping measure after positioning, which leads to the displacement of the positioned components and deformation of components during welding, resulting in slow production efficiency and defective product quality.

[0019] The following provides a complete and detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0020] As Figure 1 shown, a tooling for the quick positioning of a speed limiter base and prevention of welding deformation, which is characterized by including: a large body plate 1 and a bottom plate 2. The length of the bottom plate 2 is greater than or equal to the width of the speed limiter base. The bottom plate 2 is horizontally and perpendicularly fixedly connected to the bottom surface at the bottom end in the width direction of the large body plate 1. There are 2 protrusions on the bottom plate 2 in the front direction of the large body plate 1, which are in concave-convex clearance fit with the central holes of the left and right bottom plates of the speed limiter base. The height of the protrusions is less than the depth of the central holes. It also includes several support plates 5 fixed in the middle of the large body plate parallel to the bottom plate. The support plates 5 are in contact with the support arms of the speed limiter base 2. It further includes a baffle plate 3 fixed at the front end of the large body plate parallel to the bottom plate, whose length is less than the inner distance between the two support arms of the speed limiter base 2. The distance between the length of the support arm of the speed limiter base minus the distance between the baffle plate 3 and the bottom plate 2 is a small distance. There is a protrusion on the baffle plate 3 that is in concave-convex clearance fit with the central hole of the top plate of the speed limiter base, and the height of the protrusion is greater than the sum of the small distance and the depth of the central hole of the top plate of the speed limiter base. It also includes a support plate 4 fixed at the front end of the large body plate 1 parallel to the bottom plate. The upper surface of the support plate 4 is in contact with the top plate of the speed limiter base. It further includes several pressurizing devices 6 for pressurizing the top plate of the speed limiter base. When in use, first place the right bottom plate and the left bottom plate of the speed limiter base on the welding tooling bottom plate 2. The hole positions of the two bottom plates of the speed limiter base 2 are respectively sleeved on the 2 protrusions on the tooling bottom plate 2. Then place the two support arms of the speed limiter base on the support plates 5 according to the drawing positions. The bottom ends of the two support arms are closely against the left and right bottom plates of the speed limiter base. Then lean the top plate of the speed limiter base against the baffle plate 3. The hole position of the top plate of the speed limiter base is sleeved on the protrusion of the baffle plate 3. The upper surface of the support plate 4 is in contact with the top plate of the speed limiter base. Finally, use the quick clamping device 6 to clamp the top plate of the speed limiter base, the two support arms, and the left and right bottom plates of the speed limiter base. Rotate the operating part of the pressurizing device 6. Since the length of the baffle plate 3 is less than the inner distance between the two support arms of the speed limiter base 2, and there is a small distance between the baffle plate 3 and the top plate of the speed limiter base, and there is a protrusion on the baffle plate 3 that is in concave-convex clearance fit with the central hole of the top plate of the speed limiter base, the top plate of the speed limiter base, the two support arms, and the left and right bottom plates of the speed limiter base are closely fitted together within the tolerance of the accuracy requirements under the pressure applied by the pressurizing device. Then fix the components of the speed limiter base under the accuracy requirements, first spot-weld and then perform welding operations until the speed limiter base is completely manufactured successfully.

[0021] Specifically, the number of the support plates 5 of the tooling for the quick positioning of the speed limiter base and prevention of welding deformation is 2, which can balance the speed limiter base and control costs.

[0022] Specifically, the upper surface of the tooling support plate 5 for rapid positioning of the speed limiter base and prevention of welding deformation is arc-shaped, which can reduce the friction between the support plate 5 and the two support arms of the speed limiter.

[0023] Specifically, the protrusion of the tooling baffle 3 for rapid positioning of the speed limiter base and prevention of welding deformation is located at the center of the baffle, which is more conducive to the balance of the top plate of the speed limiter base.

[0024] Specifically, the upper surface of the tooling support plate 4 for rapid positioning of the speed limiter base and prevention of welding deformation is arc-shaped, which can reduce the friction between the upper surface of the support plate and the top plate of the speed limiter.

[0025] Specifically, the outer surface of the tooling bottom plate 2 for rapid positioning of the speed limiter base and prevention of welding deformation has a steel frame support for abutment, which can play a better limiting role.

[0026] Specifically, the number of the tooling pressurizing devices 6 for rapid positioning of the speed limiter base and prevention of welding deformation is 2, which can balance work efficiency and cost.

[0027] Specifically, the tooling pressurizing device 6 for rapid positioning of the speed limiter base and prevention of welding deformation is a manual screw press, which can better adjust the pressure applied by the pressurizing device.

[0028] The above is only an exemplary embodiment of the present application, and is not used to limit the protection scope of the present application. The protection scope of the present application is determined by the appended claims.
