A welding robot bucket-shaped welding fixture table

Abstract

This utility model discloses a welding fixture for a welding robot's bucket-shaped segments. The fixture includes a support with a first clamping assembly for clamping the bucket body. A vertically oriented positioning rod is connected to the middle of the support via a connecting rod. Second clamping assemblies for clamping the bucket segments are respectively provided at both ends of the positioning rod. This allows the inner arc surface of the bucket segment to fit against the positioning rod, and the outer arc surface of the bucket segment to fit against the inner arc surface of the bucket body. This solves the problem of uncontrollable welding quality caused by the difficulty in accurately positioning and securing the bucket and segments during welding operations due to their special configuration.

Description

Technical Field

[0001] This utility model relates to the field of bucket and ferrule processing, specifically to a welding fixture table for welding robot ferrules. Background Technology

[0002] Grab buckets are often equipped with arc-shaped flaps to ensure a tight seal when closed, allowing them to hold more material and improving volumetric efficiency. During manufacturing, the flaps are typically welded to the inner arc surface of the grab bucket. Due to the special configuration of the grab bucket and flaps, precise positioning and fastening during welding are difficult, leading to uncontrollable welding quality. Utility Model Content

[0003] The purpose of this invention is to provide a welding robot bucket and lobe welding fixture, which solves the problem that due to the special configuration of the grab and lobe, it is difficult to accurately position and fasten them during the welding process, resulting in uncontrollable welding quality.

[0004] To achieve the above objectives, this utility model provides a welding robot bucket-shaped welding fixture platform, which includes a support and a first clamping component for clamping the bucket body.

[0005] The middle part of the support is connected to a positioning rod arranged in the vertical direction via a connecting rod, and the two ends of the positioning rod are respectively provided with a second clamping assembly for clamping the bucket body;

[0006] This allows the inner arc surface of the bucket body to fit against the positioning rod, and the outer arc surface of the bucket body to fit against the inner arc surface of the grab bucket body.

[0007] Preferably, the second clamping assembly includes a slide bar disposed at the end of the positioning rod, a pressure block slidably disposed on the slide bar, and a locking screw disposed on the pressure block;

[0008] The positioning rod has a screw hole that mates with the locking screw;

[0009] This allows the pressure block to press the bucket body firmly against the positioning rod.

[0010] Preferably, the lower end of the positioning rod is provided with an L-shaped positioning element;

[0011] This allows the flapper body to engage between the vertical section of the L-shaped positioning member and the positioning rod.

[0012] Preferably, the first clamping assembly includes a screw rotatably disposed on the support;

[0013] The lower end of the screw is fixed with a lower support plate;

[0014] An adjusting nut is screwed onto the upper end of the screw, and an upper support plate is fixed to the adjusting nut.

[0015] Preferably, the support is provided with a slide rail, and a slider is slidably provided on the slide rail, the slider being connected to the upper support plate.

[0016] Preferably, the support is provided with a bearing, and the screw is at least partially rotatably disposed within the bearing.

[0017] Preferably, both the upper support plate and the lower support plate are provided with metal positioning seats.

[0018] Beneficial Effects: This utility model provides a welding fixture for welding robot bucket segments. The welding fixture includes a support, on which a first clamping assembly for clamping the grab bucket body is provided. A positioning rod arranged vertically is connected to the middle of the support via a connecting rod. Second clamping assemblies for clamping the bucket segments are respectively provided at both ends of the positioning rod. This allows the inner arc surface of the bucket segment to fit against the positioning rod, and the outer arc surface of the bucket segment to fit against the inner arc surface of the grab bucket body. In actual operation, the inner arc surface of the bucket segment is pressed against the positioning rod, and its upper and lower ends are locked using the second clamping assemblies. Then, the inner arc surface of the grab bucket body is pressed against the outer arc surface of the bucket segment, and the two ends of the grab bucket body are locked using the first clamping assembly. The welding robot then welds the contact area between the grab bucket body and the bucket segment. The welding fixture provided by this utility model can effectively position and clamp the grab bucket and the bucket segments, solving the problems of inconsistent assembly of the grab bucket and the bucket segments during welding and uncontrollable welding quality.

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] like Figure 1-5 As shown: This utility model provides a welding robot bucket-shaped welding fixture table, which includes a support 1. The support 1 is provided with a first clamping component 4 for clamping the grab bucket body 2. The middle part of the support 1 is connected to a positioning rod 6 arranged in a vertical direction through a connecting rod 5. The two ends of the positioning rod 6 are respectively provided with second clamping components for clamping the bucket-shaped body 3. This allows the inner arc surface of the bucket-shaped body 3 to fit with the positioning rod 6, and the outer arc surface of the bucket-shaped body 3 to fit with the inner arc surface of the grab bucket body 2. In actual operation, the inner arc surface of the bucket body is pressed against the positioning rod, and its upper and lower ends are locked using the second clamping assembly. Then, the inner arc surface of the grab bucket body is pressed against the outer arc surface of the bucket body, and the two ends of the grab bucket body are locked using the first clamping assembly. The welding robot is used to weld the contact area between the grab bucket body and the bucket body. The welding fixture table provided by this utility model can effectively position and clamp the grab bucket and the bucket body, solving the problems of inconsistent assembly of the grab bucket and the bucket body and uncontrollable welding quality.

[0030] In a preferred embodiment of this utility model, the second clamping assembly includes a slide rod 9 disposed at the end of the positioning rod 6, a pressure block 8 slidably disposed on the slide rod 9, and a locking screw 10 disposed on the pressure block 8; the positioning rod 6 has a screw hole that mates with the locking screw 10; so that the pressure block 8 can press the bucket body 3 onto the positioning rod 6. By twisting the locking screw, it is twisted into the screw hole of the positioning rod, thereby pressing the bucket body onto the positioning rod by the pressure block.

[0031] In a preferred embodiment of this utility model, an L-shaped positioning element 7 is provided at the lower end of the positioning rod 6, so that the bifurcation body 3 can be engaged between the vertical section of the L-shaped positioning element 7 and the positioning rod 6.

By rotating the screw, the adjusting nut can be moved downwards, thereby pressing the grab body onto the lower support plate using the upper support plate. The thread on the screw is designed with a helix angle smaller than the friction angle to prevent self-spinning and loosening under vibration. A motor with a self-locking function can also be installed on the support, connected to the screw, driving the screw to rotate in both directions.

[0033] In a preferred embodiment of this utility model, in order to limit the displacement of the upper support plate, a slide rail 41 is provided inside the support 1, and a slider 44 is slidably provided on the slide rail 41, the slider 44 being connected to the upper support plate 42.
