Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal barrel processing, in particular to a guide structure for metal barrel processing. Background Art
[0002] Metal barrels are usually processed by three methods, namely stamping, rolling and sheet metal splicing, according to their uses and requirements. Among them, stamping is the most efficient and common.
[0003] The stamping process of metal barrels is generally to use a stamping machine and a stamping die to stamp and shape a circular metal plate into a metal barrel prototype with a convex edge, and then go through processes such as trimming, grinding, and polishing to make a metal barrel. Since the placement of the circular metal plate relative to the stamping die is not fixed, the convex edge of the metal barrel has inconsistent width after stamping, so the convex edge needs to be trimmed and shaped.
[0004] At present, when cutting the flange of a metal barrel, the metal barrel is generally turned upside down on a support. The support is provided with a circular or annular protrusion whose outer diameter is adapted to the inner diameter of the metal barrel. The protrusion can limit the position of the metal barrel, but it is difficult to prevent the metal barrel from being skewed due to the side force when the metal barrel is rotated to cut the flange. There is a situation where the cutting accuracy of the flange of the metal barrel is reduced due to the metal barrel, and the metal barrel may even be scrapped. Utility Model Content

[0029] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.
[0030] As Figures 1 to 6 shown, a guiding structure for metal barrel processing includes an operating table 1, a double - head clamping member 2 and a linear driving assembly 3. A pair of double - head clamping members 2 are arranged on the operating table 1 in opposite directions, and at least one double - head clamping member 2 is slidably arranged on the operating table 1;
[0031] The double - head clamping member 2 includes a sliding arm 201, an inner chuck 202 and an outer chuck 203. A sliding groove 4 for the sliding arm 201 to be embedded and slide is arranged on the operating table 1. The inner chuck 202 and the outer chuck 203 are respectively arranged at both ends of the sliding arm 201. The linear driving assembly 3 is connected to the sliding arm 201 and drives the sliding arm 201 to reciprocate along both ends.
[0032] Specifically, a gap is formed between the inner clamp 202 and the outer clamp 203 located on the same side of a pair of double-headed clamps 2 for the metal barrel to be inserted upside down. When the metal barrel is inserted upside down into the gaps at both ends of the pair of double-headed clamps 2, the linear drive component 3 embedded in the sliding connection drives the double-headed clamp 2 to move, so that the inner clamp 202 and the outer clamp 203 on the same side are close to each other, and the movement of the inner clamp 202 and the outer clamp 203 is used to push the metal barrel that deviates from the processing position to move until the inner clamps 202 and the corresponding outer clamps 203 at both ends clamp the metal barrel. At this time, the metal barrel is moved to the processing position and is restricted from moving.
[0033] The inner clamp 202 and the outer clamp 203 on the same side only need to contact or even fit with the wall of the metal barrel, and there is no need to clamp the metal barrel wall with great force to meet the rotation requirements of the metal barrel. The metal barrel can rotate relative to the cutting device by itself, or the operating table drives the metal barrel to rotate, or the cutting device can rotate around the metal barrel.
[0034] Among them, the inner clamp 202 and the outer clamp 203 both preferably adopt an arc structure, and when the inner clamp 202 and the outer clamp 203 clamp the wall of the metal barrel, the outer side of the inner clamp 202 and the inner side of the outer clamp 203 are both in contact with the wall of the metal barrel to adapt to the structural characteristics of the metal barrel and the need for the metal barrel to rotate.
[0035] In addition, the flange of the metal barrel is inserted into the clearance groove 5 between the outer clamp 203 and the sliding arm 201, and the width of the clearance groove 5 is greater than the width of the unprocessed flange of the metal barrel. Therefore, when the outer clamp 203 clamps the metal barrel, the metal barrel can be prevented from being skewed during the flange cutting process, so as to ensure the stability and accuracy of the processing of the flange of the metal barrel.
[0036] Preferably, the sliding arm 201 includes two racks, and the sliding groove 4 is arranged corresponding to the number of racks of the sliding arm 201, so as to facilitate the stability of the inner clamp 202 and the outer clamp 203, and increase the structural strength of the double-head clamp 2.
[0037] When a pair of double-headed clamping members 2 are both slidably disposed on the operating table 1, four slide grooves 4 are disposed on the operating table 1, and two racks of a sliding arm 201 are respectively slidably disposed in two slide grooves 4 located on the outer sides. In addition, linkage gears 6 are rotatably disposed on both sides of the operating table 1, and the two racks located on the same side of the two sliding arms 201 are connected through the linkage gear 6, and the side surfaces of the racks are provided with teeth meshing with the linkage gear 6. A notch is disposed on the operating table 1 for the linkage gear 6 to be installed, and the notch is communicated with two adjacent slide grooves 4 on the same side.
[0038] On the one hand, it is conducive to streamlining the structure and quantity of the linear drive assembly 3. On the other hand, the synchronous movement of the two double-headed clamping members 2 is achieved. Compared with the movement mode of a single double-headed clamping member 2, when the distances between the outer clamping heads 203 and the inner clamping heads 202 and the barrel wall of the metal barrel are constant, the synchronous movement of the two double-headed clamping members 2 can position the metal barrel faster.
[0039] Among them, the linear drive assembly 3 includes a cylinder 301 and a "T"-shaped slider 302. The cylinder 301 is arranged at the bottom of the operating table 1. The "T"-shaped slider 302 is located at the bottom below the operating table 1 and is connected to the cylinder 301. Both sides of the top of the "T"-shaped slider 302 are respectively connected to two racks. The cylinder 301 is arranged at the bottom of the operating table 1 to facilitate aesthetics and avoid negative impacts on the operation of workers. And the cylinder 301 drives the two inner racks through the "T"-shaped slider 302, that is, drives the double-headed clamping member 2 located inside to move, which is conducive to the uniform force on both sides of the double-headed clamping member 2, so that the double-headed clamping member 2 can move stably and clamp the metal barrel.
[0040] Correspondingly, a sliding hole 7 for the "T"-shaped slider 302 to pass through is arranged on the operating table 1. A counterbore 8 for the top of the "T"-shaped slider 302 to slide is arranged at the top of the operating table 1. The sliding hole 7 and the sliding groove 4 are both located between the two inner sliding grooves 4. The counterbore 8 is communicated with the sliding hole 7 and the two inner sliding grooves 4.
[0041] In addition, a stop spring plate 9 is arranged on the operating table 1. The stop spring plate 9 is located between the two outer clamping heads 203. The stop spring plate 9 is in sliding contact or clearance fit with the top of the "T"-shaped slider 302 and all the racks, so as to prevent the sliding arm 201 from jumping and affecting the performance of the double-headed clamping member 2.
[0042] As is known by common technical knowledge, the present utility model can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present utility model or within the scope equivalent to the present utility model are encompassed by the present utility model.
