Technical Field

[0001] This utility model belongs to the field of elbow processing technology, and in particular relates to a fixture for elbow beveling. Background Technology

[0002] The beveling of elbows mainly involves processing the ends of the elbows to create a beveled structure that is easy to weld or connect in other ways. In the existing technology, a set of processing equipment with dual cutting devices is used to simultaneously cut both ends of the elbows. The elbows are placed on a rotatable fixture and processed one by one by rotating the fixture.

[0003] Currently, the elbow processing technology requires continuous loading and unloading of elbows during the material handling process. The interval between upstairs and downstairs operations is short, resulting in a heavy workload for the personnel or corresponding machinery responsible for loading and unloading.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This utility model embodiment provides a fixture for processing elbow beveling, such as Figures 1-5 As shown, a fixture for beveling elbows is used in an existing elbow beveling machine. The elbow beveling machine mainly includes a gantry frame 110 and two sets of processing mechanisms 120. The two sets of processing mechanisms 120 are arranged opposite each other and can simultaneously cut the two end faces of the elbow. The end of the processing mechanism 120 is also provided with a telescopic structure that can hold against the end face of the elbow during the processing.

[0026] The fixtures used for beveling elbows include:

[0027] A sliding fixture table 300 includes a sliding plate 310 and an elbow clamp 320 for fixing elbows. The number of elbow clamps 320 is several sets and the elbow clamps 320 are arranged on the sliding plate 310. The sliding plate 310 is provided with a drive rack 330 for transmission.

[0028] The driving mechanism includes a base plate 410 and a guide rail 420 disposed on the base plate 410. The sliding plate 310 is provided with a sliding groove 301, and the sliding plate 310 slides on the guide rail 420 through the sliding groove 301. The sliding groove 301 is adapted to the guide rail 420. The base plate 410 is provided with a driving mechanism that drives the driving rack 330 to move. The driving rack 330 is disposed on one side of the sliding plate 310, and the driving mechanism and the driving rack 330 are disposed on the same side of the sliding plate 310.

[0029] The sliding plate 310 and the base plate 410 are spaced apart. The guide rail 420 lifts the sliding plate 310 and the base plate 410 to form a gap, which prevents waste chips from falling into the base plate 410 and affecting the sliding. At the same time, the guide rail 420 adopts a sloping design structure to reduce the depression and prevent waste chips from affecting the track. This part of the structure can also refer to the design of other cutting feeding guide rail technologies in the prior art.

[0030] The clamping mechanism 200 adopts an existing technology for elbow fixing structure composed of a clamping fixture and a hydraulic rod. It is suspended above the base plate 410 by fixing it to the gantry frame 110. When the sliding clamping table 300 drives the elbow clamps 320 to pass through the clamping mechanism 200 one by one, both the elbow clamps 320 and the clamping mechanism 200 are provided with arc-shaped grooves. When the clamping mechanism 200 and the elbow clamps 320 that have passed through the clamping mechanism 200 cooperate with each other, the arc-shaped grooves are connected to form an arc-shaped clamping cavity for fixing the elbow. The clamping mechanism 200 and the elbow clamps 320 that have passed through the clamping mechanism 200 cooperate to clamp the elbow.

[0031] In this application, the sliding fixture table 300 batches elbows through an elbow beveling machine. The movement of the sliding fixture table 300 mainly relies on the cooperation of the drive mechanism and the drive rack 330 to achieve precise movement, ensuring that the elbow clamp 320 can accurately stop the elbow below the clamping mechanism 200. The batching of fixtures by the sliding fixture table 300, combined with automated equipment, improves production efficiency.

[0032] In a preferred embodiment of this invention, the teeth of the drive rack 330 face the ground. The drive rack 330 is a common rack structure. With the teeth facing down, it is less likely for chips generated during the cutting process to have an impact. The drive mechanism includes a support base 440 fixed to the sliding plate 310 and a motor mechanism 430 disposed on the support base 440. The power output shaft of the motor mechanism 430 is provided with a drive gear that meshes with the teeth of the drive rack 330.

[0033] In this embodiment, a shielding shed 340 of the same length as the drive rack 330 can also be provided above the drive rack 330, making it less likely for debris to reach the drive rack 330. Furthermore, during the movement, the shielding shed 340 will also shield the drive gear of the motor mechanism 430, making it less likely for debris to interfere with the drive gear.

[0034] The motor mechanism 430 described here uses an existing mature closed-loop stepper motor or servo motor with an encoder, which can precisely control the number of rotations, making the movement distance of the sliding fixture table 300 controllable. This ensures that the elbow fixture 320 can accurately stop the elbow below the clamping mechanism 200. It should be noted that the movement stroke of the sliding fixture table 300 is also controlled by encoding. After all the elbows on the elbow fixture 320 have been processed, it will automatically reverse and pull the sliding fixture table 300 back to its initial position. The operator can then manually remove the elbows processed by the elbow fixture 320 and place a new elbow to be processed.

[0035] Alternatively, a continuous processing method can be adopted. For example, when the sliding fixture table 300 completes the processing of the last group or two groups of elbows, the specific time is matched according to the elbow specifications, material changing rate and cutting rate. The elbows that have been processed and have left the processing area from one side of the equipment are manually removed and replaced with unprocessed elbows. After the last group is completed, the sliding fixture table 300 slides in the opposite direction to pull the unprocessed elbows back into the processing area. The processing is completed in sequence. When the last group or two groups are reached, the processed elbows are manually removed and replaced with unprocessed elbows on the other side. This cycle is repeated so that the equipment can carry out construction continuously.

[0036] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.
