Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile manufacturing, and in particular to an upper row clamping device for aluminum surface treatment. Background Art

[0002] In the field of aluminum production, several aluminum profiles are fixed to a conductive frame at required intervals by means of an upper row device. Subsequently, several aluminum profiles fixed to the conductive frame are subjected to surface treatment processes such as oxidation, coloring, electrophoresis, and cleaning. Finally, several aluminum profiles are detached from the conductive frame by means of a lower row device. Among them, the conductive frame mainly includes a large beam and two conductive rods vertically installed on the large beam. The current upper row process is generally as follows: First, a lifting unit supports the large beam of the conductive frame and moves it downward, so that the conductive rods are aligned with the predetermined through-hole positions and synchronously move downward to a predetermined height position. Subsequently, the lifting unit supports the large beam and the conductive rods and gradually moves upward synchronously. During the upward movement, the clamp shown in Figure 5 is opened manually or with the help of an upper row device, so as to clamp the aluminum profiles onto the conductive rods one by one.

[0005] In summary, the existing upper row equipment has a relatively complex structure. Firstly, there are certain defects in the pre-positioning and pre-treatment of the conductive rod. Secondly, the clamp opening mechanism for opening the clamp is complex in structure, with high design and assembly difficulties, and cannot meet the requirements of manufacturers. Summary of the Invention

SPECIFIC EMBODIMENTS

[0022] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0023] See the attached Figures 1 to 5 As shown, in this embodiment, a clamping mechanism of an upper row clamping device for aluminum surface treatment includes an open clamping machine base 11, a track movable plate 12, an open clamping slide base 13, an intermediate movable plate 15, a main horizontal driving unit 16, a main vertical driving unit 17, an open clamping unit 14, an opening plate 18, an open clamping telescopic member 123 and a reset elastic member 124. Among them, a vertically arranged vertical slide rail is arranged between the intermediate movable plate 15 and the open clamping machine base 11, that is, the track of the vertical slide rail here is installed on the open clamping machine base 11 and the slider of the vertical slide rail is installed on the intermediate movable plate 15, thereby realizing that the intermediate movable plate 15 can slide vertically relative to the open clamping machine base 11; a horizontally arranged horizontal slide rail is arranged between the intermediate movable plate 15 and the track movable plate 12, that is, the track of the horizontal slide rail here is installed on the intermediate movable plate 15 and the slider of the horizontal slide rail is installed on the track movable plate 12, thereby realizing that the track movable plate 12 can slide horizontally relative to the intermediate movable plate 15. Secondly, the main horizontal driving unit 16 acts on the track movable plate 12 to slide horizontally; the main vertical driving unit 17 acts on the track movable plate 12 to slide vertically.

[0024] Specifically, the main horizontal driving unit 16 includes a horizontal driving connecting rod 162 and a horizontally driving cam 161 that can rotate around a fixed axis. Among them, the front end of the horizontal driving is movably connected to a vertically arranged sliding hole 121 pre-opened on the track movable plate 12, and the tail end of the horizontal driving connecting rod 162 is movably connected to the horizontally driving cam 161; the horizontally driving cam 161 is rotatably installed on the open clamping machine base 11.

[0025] Specifically, the main vertical driving unit 17 includes a vertical driving connecting rod 172 and a vertically driving cam 171 that can rotate around a fixed axis. Among them, the upper end of the vertical driving connecting rod 172 is movably connected to a horizontally arranged sliding hole 122 pre-opened on the track movable plate 12, and the lower end of the vertical driving connecting rod 172 is movably connected to the vertically driving cam 171; the vertically driving cam 171 is rotatably installed on the open clamping machine base 11.

[0026] Further, both the above-mentioned horizontal drive link 162 and vertical drive link 172 are mounted on the clip-opening machine base 11 through limit sliders. Thus, the horizontal drive link 162 can only move horizontally in the front-back direction, and the vertical drive link 172 can only move vertically in the up-down direction. In addition, by providing a vertical sliding hole 121 for the front end of the horizontal drive to be movably connected, and by providing a horizontal sliding hole 122 for the upper end of the vertical drive link 172 to be slidably connected, the main vertical drive unit 17 and the main vertical drive unit 17 can act independently or simultaneously without interfering with each other.

[0027] Therefore, by means of the rotational power of the horizontal drive cam 161 and the vertical drive cam 171, the track flap 12 is respectively driven to make horizontal sliding and / or vertical sliding through the horizontal drive link 162 and the vertical drive link 172.

[0028] In this embodiment, the horizontal drive cam 161 and the vertical drive cam 171 are driven to rotate synchronously by the same drive motor, that is, through a synchronous belt (which can be in the form of a belt, a chain, etc.) that sequentially loops around the output shaft of the drive motor, the shaft end of the horizontal drive cam 161, and the shaft end of the vertical drive cam 171, so as to realize the simultaneous horizontal sliding and vertical sliding of the track flap 12.

[0029] In this embodiment, those skilled in the art can correspondingly set parameters such as the diameter width and shape of the horizontal drive cam 161 and the vertical drive cam 171 according to the action requirements of actual production, so as to realize the required action trajectory of the track flap 12. This is not limited here, and derivative technical solutions can be adopted.

[0030] In this embodiment, a horizontally arranged horizontal slide rail is configured between the clip-opening slide seat 13 and the track flap 12, that is, the track of the horizontal slide rail here is installed on the track flap 12 and the slider of the horizontal slide rail is installed on the clip-opening slide seat 13. Secondly, the clip-opening telescopic member 123 and the reset elastic member 124 are arranged on the track flap 12. Among them, the telescopic end of the clip-opening telescopic member 123 abuts against the tail end of the clip-opening slide seat 13 and is used to drive the clip-opening slide seat 13 to slide forward horizontally; the reset elastic member 124 acts on the front end of the clip-opening slide seat 13 and is used to drive the clip-opening slide seat 13 to slide backward horizontally. Specifically, when the telescopic end of the clip-opening telescopic member 123 extends forward, it gradually abuts against the clip-opening slide seat 13 and drives it to slide forward horizontally, and at the same time the reset elastic member 124 is compressed and stores energy; when the telescopic end of the clip-opening telescopic member 123 retracts backward, the reset elastic member 124 releases elastic kinetic energy to drive the clip-opening slide seat 13 to slide backward horizontally. Thus, the clip-opening slide seat 13 can slide horizontally relative to the track flap 12. In addition, the clip-opening slide seat 13 can also move vertically and horizontally synchronously with the track flap 12.

[0031] Further, the above-mentioned clip-opening telescopic member 123 is preferably a telescopic cylinder, and the reset elastic member 124 is preferably a spring member. The two ends of the spring member are respectively connected to the front end of the clip-opening slide 13 and the track flap 12.

[0032] In this embodiment, the clip-opening unit 14 includes a push rod 141, two clip-opening connecting plates 142, and two clip-opening needles 143 vertically arranged at the front ends of the two clip-opening connecting plates 142. The tail ends of the two clip-opening connecting plates 142 are jointly hinged to the front end of the push rod 141, and the push rod 141 is fixedly connected to the clip-opening slide 13. The two clip-opening needles 143 are used to be inserted into the opening and closing control positions of the clamp. As the clip-opening slide 13 moves forward, the two clip-opening needles 143 are driven by the push rod 141 and the two clip-opening connecting plates 142 to overcome the elastic force of the clamp to open the clamp. Conversely, under the elastic force of the clamp and the elastic force of the reset elastic member 124, the clip-opening slide 13 moves backward.

[0033] In this embodiment, it further includes an upper clamping mechanism 5 arranged adjacent to the clip-opening mechanism 1. The upper clamping mechanism 5 includes an upper clamping conveying channel 51 and an upper clamping conveying track 52. The upper clamping conveying channel 51 is used to carry the clamp. The upper clamping conveying channel 51 is provided with a clip outlet, and the clip outlet is relatively located above the clip-opening unit 14, so as to facilitate the clip-opening unit 14 to perform upper clamping and clip-opening operations on the clamp conveyed to the clip outlet. The upper clamping conveying track 52 is arranged adjacent to the upper clamping conveying channel 51. The upper clamping conveying track 52 is provided with a plurality of upper clamping blocks 521 arranged at equal intervals. With the directional cyclic movement of the upper clamping conveying track 52, each upper clamping block 521 cooperates with the upper clamping conveying channel 51 to push each clamp to move forward toward the clip outlet in turn, so as to realize the continuous feeding supply function of the clamp.

[0034] Specifically, the upper clamping conveying track 52 is driven by a motor in cooperation with a transmission gear.

[0035] In this embodiment, the opening plate 18 can slide vertically relative to the track flap 12, wherein a vertical slide rail is arranged between the opening plate 18 and the track flap 12 of this embodiment, wherein the guide rail of the vertical slide rail is installed on the track flap 12 and the slider of the vertical slide rail is connected to the opening plate 18. Secondly, an obliquely arranged oblique sliding hole 181 is provided on the opening plate 18, and an opening pulley 131 movably connected to the oblique sliding hole 181 is provided on the clamping slide seat 13, thereby utilizing the oblique sliding hole 181 to slide relative to the opening pulley 131, thereby using the oblique sliding hole 181 to simultaneously limit the front and rear sliding distance of the clamping slide seat 13 relative to the track flap 12 and the front and rear moving distance of the push rod 141, thereby limiting the opening and closing angle of the two-open clamping connecting plate 142, and finally realizing the control of the opening size of the two-open clamping needles 143, that is, the longer the relative sliding distance of the opening pulley 131 provided by the oblique sliding hole 181 is, the larger the opening of the two-open clamping needles 143 is; conversely, the shorter the relative sliding distance of the opening pulley 131 provided by the oblique sliding hole 181 is, the smaller the opening of the two-open clamping needles 143 is.

[0036] To facilitate the understanding of the above-mentioned clamping mechanism 1 and clamping mechanism 5, the specific working principles are explained below.

[0037] During operation, the main horizontal driving unit 16 and the main vertical driving unit 17 are first used to drive the clamping slide 13 and the track flap 12 to move synchronously, so that the two clamping pins 143 of the clamping unit 14 are aligned with the clamp located at the clamp outlet of the upper clamp conveying channel 51. Subsequently, the main vertical driving unit 17 drives the clamping slide 13 and the track flap 12 to move upward synchronously, so that the two clamping pins 143 of the clamping unit 14 are inserted into the opening and closing control position of the clamp. Next, the extending action of the clamping telescopic member 123 drives the clamping slide 13 to slide forward so that the two clamping needles 143 open the clamp. Finally, the main horizontal drive unit 16 and the main vertical drive unit 17 drive the clamping slide 13 and the track flap 12 to move synchronously. After the clamp moves to the predetermined position, the retracting action of the clamping telescopic member 123 and the elastic action of the reset elastic member 124 make the two clamping needles 143 no longer support the clamp, so that the clamp closes and clamps the aluminum material on the conductive rod. Finally, each driving element is reset to make the two clamping needles 143 disengage from the clamp to complete a single clamping operation.

[0038] By repeating the above actions and cooperating with the clamping mechanism 5 to continuously feed the clamp, the continuous clamping operation of the clamp is achieved.

[0039] The above-described embodiments are only preferred embodiments of the present invention and do not impose any formal limitations on the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, can make more possible changes, refinements, or modifications to the technical solution of the present invention by using the disclosed technical content, which are all equivalent embodiments of the present invention. Therefore, all equivalent changes made in accordance with the idea of the present invention without departing from the content of the technical solution of the present invention should be covered within the protection scope of the present invention.
