A fixture for drilling angle brackets of new energy assembly aluminum profiles

Abstract

This utility model relates to a fixture for drilling corner brackets of aluminum profiles for new energy assembly, including a worktable, a first support plate, a second support plate, a first clamping cylinder, and a second clamping cylinder. The support plate is vertically mounted on the worktable, with its inner side forming an angle consistent with the opening angle of the corner bracket, and its height is lower than that of the corner bracket. The pressure plate of the first clamping cylinder is parallel to the reinforcing rib of the corner bracket and clamps laterally, while the pressure plate of the second clamping cylinder clamps the top of the corner bracket vertically. Through the adjustable-angle support structure and multi-directional clamping mechanism, it can adapt to extrusion corner brackets of different specifications, solving the problems of poor versatility and low positioning accuracy of existing fixtures, significantly improving drilling efficiency and product consistency. Combined with the third clamping cylinder and the angle-adjustable cylinder bracket, it can be better integrated into automated drilling equipment.

Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing tooling, and is particularly applicable to drilling fixtures for extruded aluminum profile corner codes in new energy equipment, specifically relating to a fixture for drilling aluminum profile corner codes in new energy assembly. Background Technology

[0002] In the assembly of new energy equipment (such as photovoltaic brackets and energy storage cabinets), aluminum profile corner brackets are key connecting components. Corner brackets are divided into two categories: extruded corner brackets and die-cast corner brackets. Extruded corner brackets are the preferred choice in the new energy field due to their high strength, high load-bearing capacity, and processing flexibility. Extruded corner brackets are formed by melting aluminum ingots and extruding them into continuous long strips, followed by secondary processing such as sawing and drilling. Common opening angles for extruded corner brackets include 45°, 60°, 90°, 120°, and 135°, among others. Figure 5 As shown in the figure, traditional drilling requires frequent fixture changes, which is inefficient; existing fixtures are also not suitable for use in automated drilling equipment for mass production. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects in the existing technology and provide a fixture for drilling corner codes of aluminum profiles for new energy assembly.

[0004] To achieve the above objectives, the technical solution of this utility model is to design a fixture for drilling corner codes of aluminum profiles for new energy assembly, including a workbench, a first support plate, a second support plate, a first clamping cylinder, and a second clamping cylinder. The first and second support plates are vertically mounted on the workbench, and a certain included angle is formed between the inner sides of the first and second support plates, which is consistent with the opening angle of the corner code. The height of the first and second support plates is less than the height of the corner code. The first and second clamping cylinders are both mounted on the workbench. The first pressure plate on the first clamping cylinder is located on one side of the corner code reinforcing rib and is parallel to the reinforcing rib. The second pressure plate of the second clamping cylinder is located above the corner code.

[0005] Furthermore, the worktable is provided with a first arc-shaped sliding groove, and a first arc-shaped slider that mates with the first arc-shaped sliding groove is provided below the first support plate and / or the second support plate. A first locking bolt is installed on the first arc-shaped slider. The first arc-shaped sliding groove and the first arc-shaped slider cooperate with each other to allow the first support plate and / or the second support plate to be angled. Thus, when changing angle brackets with different opening angles, the included angle between the first support plate and the second support plate is always consistent with the opening angle of the angle bracket. When clamped, the two sides of the angle bracket can always fit against the inner sides of the first support plate and the second support plate. The first locking bolt can lock and fix the first support plate and / or the second support plate to prevent angle deviations during operation and affect drilling accuracy.

[0006] Furthermore, a second arc-shaped groove is provided on the worktable, and a second arc-shaped slider that mates with the second arc-shaped groove is provided below the first clamping cylinder. A second locking bolt is installed on the second arc-shaped slider. The second arc-shaped groove and the second arc-shaped slider cooperate with each other, enabling the first clamping cylinder to adjust its angle. Thus, when changing angle brackets with different opening angles, the first clamping plate is always parallel to the reinforcing rib of the angle bracket. The second locking bolt can lock and fix the second arc-shaped slider to prevent angle deviation during operation, which would affect the drilling accuracy.

[0007] Furthermore, an arc-shaped outer sleeve is connected to the outer side of the first support plate, and the arc-shaped outer sleeve is fixed to the worktable. An arc-shaped inner sleeve is connected to the outer side of the second support plate. The arc-shaped outer sleeve and the arc-shaped inner sleeve cooperate with each other, and a fourth locking bolt is installed on the arc-shaped outer sleeve. The arc-shaped inner sleeve is fitted inside the arc-shaped outer sleeve, and the two cooperate with each other to change the included angle between the first support plate and the second support plate, making it consistent with the opening angle of the angle bracket. The fourth locking bolt can lock and fix the arc-shaped inner sleeve and the arc-shaped outer sleeve, preventing angular deviations during operation and affecting drilling accuracy.

[0008] Furthermore, the worktable includes an upper worktable and a lower worktable. The arc-shaped outer sleeve and the first support plate are mounted on the upper worktable. A third arc-shaped slide rail is provided on the lower worktable. A third arc-shaped slide groove is slidably mounted on the third arc-shaped slide rail. A third locking bolt is provided on the third arc-shaped slide groove. A cylinder bracket is mounted on the third arc-shaped slide groove. The first clamping cylinder is mounted on the cylinder bracket. A third clamping cylinder is also mounted on the cylinder bracket. The third pressure plate of the third clamping cylinder is located below the corner bracket. The third arc-shaped slide rail and the third arc-shaped slide groove cooperate with each other, allowing the cylinder bracket to rotate at any angle, thereby adjusting the angle of the second and third clamping cylinders relative to the corner bracket. This ensures that the second pressure plate is always parallel to the reinforcing rib of the corner bracket, and the third pressure plate always presses against the center position below the corner bracket. The third locking bolt is sufficient to lock and fix the third arc-shaped slide rail and the third arc-shaped slide groove, preventing angular deviations during operation and affecting drilling accuracy.

[0009] Optionally, the second and / or third clamping cylinders are rotary clamping cylinders. Rotary clamping cylinders allow the entire fixture to be better integrated into the automatic drilling equipment, facilitating top loading and bottom unloading.

[0010] Optionally, the first, second, and third pressure plates are provided with elastic pads on the side near the corner bracket. The elastic pads are preferably made of rubber. The elastic pads can prevent hard contact between the pressure plates and the workpiece, thus preventing damage to the workpiece surface, and can also increase the friction between the pressure plates and the workpiece contact surface, giving them better clamping force.

[0011] The advantages and beneficial effects of this utility model are as follows: 1. A single clamping set is compatible with angle brackets of all angle specifications, making clamping more convenient; 2. By using two or three sets of cylinders for clamping, the corner code can be positioned and clamped more effectively, improving drilling accuracy.

[0012] 3. The second and third clamping cylinders are designed as rotary clamping cylinders, which can be adapted to automated drilling equipment to prevent the clamping plate from blocking the corner code from falling when feeding from above and unloading from below. Attached Figure Description

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] This utility model is a fixture for drilling corner brackets of new energy assembly aluminum profiles, including a workbench 1, a first support plate 2, a second support plate 3, a first clamping cylinder 4, and a second clamping cylinder 5. The first support plate 2 and the second support plate 3 are vertically mounted on the workbench 1, and a certain included angle is formed between the inner sides of the first support plate 2 and the second support plate 3. This included angle is consistent with the opening angle of the corner bracket 6. The height of the first support plate 2 and the second support plate 3 is less than the height of the corner bracket 6. The first clamping cylinder 4 and the second clamping cylinder 5 are both mounted on the workbench 1. The first pressure plate 401 on the first clamping cylinder 4 is located on one side of the reinforcing rib 601 of the corner bracket 6 and is parallel to the reinforcing rib 601. The second pressure plate 501 of the second clamping cylinder 5 is located above the corner bracket 6. The included angle between the inner sides of the first support plate 2 and the second support plate 3 is consistent with the opening angle of the corner bracket 6. When the first pressure plate 401 of the first pressing cylinder 4 presses the reinforcing rib 601 of the corner bracket 6, it ensures that the two outer sides of the corner bracket 6 are tightly fitted with the inner sides of the first support plate 2 and the second support plate 3 respectively, providing support. The second pressure plate 501 of the second pressing cylinder 5 presses the corner bracket 6 downward.

[0017] according to Figure 1 , 2 As shown, the workbench 1 has a first arc-shaped slide groove 111. Below the first support plate 2 and / or the second support plate 3, a first arc-shaped slider 112 is provided to cooperate with the first arc-shaped slide groove 111. A first locking bolt 113 is installed on the first arc-shaped slider 112. The first arc-shaped slider 112 drives the first support plate 2 or the second support plate 3 to move on the first arc-shaped slide groove 111. At this time, one of the first support plate 2 or the second support plate 3 is fixed to the workbench 1, serving as a fixed support plate. The other support plate's angle is adjusted through the first arc-shaped slide groove 111 and the first arc-shaped slider 112, thereby adapting to more angle brackets with different opening angles. The first arc-shaped slider 112 drives the first support plate 2 and the second support plate 3 to move on the first arc-shaped slide groove 111. At this time, both the first support plate 2 and the second support plate 3 are movable support plates, and their included angle can also be adjusted. At this point, the position of the second clamping cylinder 5 also needs to be adjusted.

[0018] according to Figure 1 , 2 As shown, the workbench 1 has a second arc-shaped slide groove 121. Below the first clamping cylinder 4, a second arc-shaped slider 122 is provided to cooperate with the second arc-shaped slide groove 121. A second locking bolt 123 is installed on the second arc-shaped slider 122. Driven by the second arc-shaped slider 122, the first clamping cylinder 4 rotates around the second arc-shaped slide groove 121, thereby changing its position so that the first clamping plate 401 is always parallel to the reinforcing rib 601, providing better clamping force.

[0019] according to Figure 3 ,4 As shown, an arc-shaped outer sleeve 7 is connected to the outer side of the first support plate 2, and the arc-shaped outer sleeve 7 is fixed on the workbench 1. An arc-shaped inner sleeve 8 is connected to the outer side of the second support plate 3. The arc-shaped outer sleeve 7 and the arc-shaped inner sleeve 8 cooperate with each other, and a fourth locking bolt 701 is installed on the arc-shaped outer sleeve 7. The first support plate 2 is fixed on the workbench 1 under the support of the arc-shaped outer sleeve 7, and the second support plate 3 is slidably engaged with the arc-shaped outer sleeve 7 under the support of the arc-shaped inner sleeve 8, thereby changing the angle between the first support plate 2 and the second support plate 3 so that it is consistent with the opening angle of the corner bracket 6.

[0020] according to Figure 3 , 4 As shown, the workbench 1 includes an upper workbench 130 and a lower workbench 140. The arc-shaped outer sleeve 7 and the first support plate 2 are installed on the upper workbench 130. The lower workbench 140 is provided with a third arc-shaped slide rail 141. A third arc-shaped slide groove 142 is slidably installed on the third arc-shaped slide rail 141. A third locking bolt 143 is provided on the third arc-shaped slide groove 142. A cylinder bracket 144 is installed on the third arc-shaped slide groove 142. The first pressing cylinder 4 is installed on the cylinder bracket 144. A third pressing cylinder 9 is also installed on the cylinder bracket 144. The third pressure plate 901 of the third pressing cylinder 9 is located below the corner bracket 6. The third arc-shaped slide rail 141 and the third arc-shaped slide groove 142 cooperate with each other, thereby driving the first clamping cylinder 4 and the third clamping cylinder 9 on the cylinder bracket 144 to rotate, thereby realizing the change of position of the first clamping cylinder 4 and the third clamping cylinder 9, so that they can better clamp the corner code 6. The upper worktable 130 and the lower worktable 140 are the same two working surfaces. There is no upper worktable 130 below the second support plate 3 and the arc-shaped inner sleeve 8, thereby ensuring that there are no obstructions at the angle formed between the first support plate 2 and the second support plate 3, and the corner code 6 can pass smoothly up and down.

[0021] The second clamping cylinder 5 and / or the third clamping cylinder 9 are rotary clamping cylinders. In automated drilling equipment, when the corner bracket 6 is unloaded from top to bottom, the rotary clamping cylinder can keep its clamping plate away from the corner bracket 6 without providing clamping force, thus not affecting the loading and unloading of the corner bracket 6.

[0022] The first pressure plate 401, the second pressure plate 501, and the third pressure plate 901 are provided with elastic pads 10 on the side near the corner bracket 6.

[0023] The bolts, nuts, screws, welding, etc. used to connect two or more parts in the above-mentioned fixing and installation are all known to those skilled in the art and will not be repeated here. The frame, workbench and other components described in this article are adjusted according to the interrelationship between the components, with the main purpose of preventing interference between different components.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
