Description

Technical Field

[0001] This utility model relates to a tooling for the side panel of a range hood. Background Technology

[0002] Some range hoods have L-shaped side panels with a 90° bend. During the stamping process of these side panels, controlling the 90° bend angle is difficult. Therefore, manual operation is required. The side panel angle is first controlled to 90°, and then the overlapping guard plates at the bend's edge are welded together. This maintains the overall 90° bend angle of the range hood side panel, resulting in a side panel with a 90° bend. However, manual operation introduces some error in controlling the bend angle. If the left / right side panel angle cannot be precisely controlled to 90 degrees, it will affect the subsequent assembly of the entire range hood. Therefore, a welding fixture is urgently needed to improve the efficiency of argon arc welding of the left / right side panels. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a range hood side panel tooling with high production efficiency and the ability to precisely control the angle of the range hood side panel to 90°, in contrast to the above-mentioned prior art.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a tooling for a side panel of a range hood, wherein the side panel of the range hood includes a first plate and a second plate that are integrally connected and arranged in a relatively perpendicular manner, and the side edges of the first plate and the second plate are bent with partially overlapping guard plates; characterized in that: it includes a platform and a coarse positioning module, a fine positioning module and a clamping module arranged on the platform;

[0005] The coarse positioning module includes a first constraint member constraining the end of the first plate and a second constraint member constraining the surface of the second plate; the fine positioning module includes a first positioning component for forming a first positioning groove in the constraint direction of the first plate and a second positioning component for forming a second positioning groove in the constraint direction of the second plate; the clamping module includes a clamp capable of clamping the overlapping position of the first plate and the second plate guard plate.

[0006] Preferably, both the first constraint member and the second constraint member are vertically arranged constraint plates.

[0007] To facilitate the insertion of the range hood side panel, the top of the constraint plate has a chamfer that guides towards the constraint side.

[0008] To facilitate the installation of the constraint plate, a mounting plate extends horizontally from the lower edge of the constraint plate toward the non-constraint side, and the mounting plate is fixed to the platform.

[0009] To enhance the strength of the constraint plate and facilitate the coarse positioning of the range hood side panel during rough positioning, a reinforcing plate is connected between the constraint plate and the mounting plate.

[0010] With a simple structure, the first positioning component includes at least two sets of constraint components distributed along the constraint direction of the first plate. Each set of positioning components includes a third constraint component and a fourth constraint component arranged opposite to each other. A gap matching the thickness of the first plate is formed between the third constraint component and the fourth constraint component. The gap formed by each set of constraint components together forms a first positioning groove that constrains the first plate.

[0011] To facilitate adjustment of the relative positions of the third and fourth constraint members, the third and fourth constraint members in each group of positioning members are mounted on the platform in a direction perpendicular to the constraint direction of the first plate.

[0012] In order to better guide the movement direction of the third and fourth constraint members and thus ensure that the constraint direction of the third and fourth constraint members remains unchanged, the platform is provided with limiting grooves corresponding to the movement direction and movement range of each third and fourth constraint member. The third and fourth constraint members are set in the limiting grooves and protrude from the surface of the platform.

[0013] With a simple structure, the second positioning component includes at least two fifth constraint members distributed along the constraint direction of the second plate. The fifth constraint members are positioned facing the second constraint members, and a gap matching the thickness of the second plate is formed between each fifth constraint member and the second constraint member. The gaps together form a second positioning groove that constrains the second plate.

[0014] In order to better adjust the gap between the fifth constraint member and the second plate, the fifth constraint member can be moved and installed on the platform in a direction perpendicular to the constraint direction of the second plate. The platform is provided with a limiting groove corresponding to the moving direction and moving range of each fifth constraint member. The fifth constraint member is set in the limiting groove and protrudes from the upper surface of the platform.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: This range hood side panel fixture utilizes a coarse positioning module to first roughly constrain the angle of the range hood side panel, and then uses a fine positioning module to achieve precise positioning of the range hood side panel, thereby achieving a precise adjustment of the range hood side panel to a 90° angle. Then, a clamp is used to clamp the overlapping guard plates, ensuring the welding quality between the overlapping guard plates, ultimately producing a range hood side panel with a stable 90° angle. This range hood side panel fixture solves the problems of low production efficiency and poor welding angles in manual welding, improves the production efficiency and product quality of range hood side panels, and facilitates subsequent assembly of the entire range hood. Attached Figure Description

[0016] Figure 1 This is a perspective view of the range hood side panel fixture in an embodiment of this utility model. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] The range hood side panel fixture in this embodiment is used to adjust the shape of the range hood side panel 100, thereby facilitating welding. The range hood side panel fixture in this embodiment can precisely control the angle of the range hood side panel 100 to 90 degrees.

[0019] The range hood side panel 100 includes a first plate 101 and a second plate 102 integrally connected and perpendicularly angled. The sides of the first plate 101 and the second plate 102 on the same side have partially overlapping guard plates 103. When the range hood side panel 100 is not placed on a range hood side panel fixture for adjustment, the included angle between the first plate 101 and the second plate 102 is not precisely 90°, making welding of the overlapping portion of the guard plate 103 impossible. Therefore, it is necessary to place the range hood side panel 100 on a range hood side panel fixture for angle adjustment. After precisely controlling the angle of the range hood side panel 100 to 90 degrees, the overlapping portion of the guard plate 103 is welded to fix the range hood side panel 100 at a 90-degree angle.

[0020] like Figure 1 As shown, the range hood side panel fixture in this embodiment includes a platform 1 and a coarse positioning module 2, a fine positioning module 3 and a clamping module 4 disposed on the platform 1.

[0021] The coarse positioning module 2 primarily provides an approximate position for the range hood side panel 100. This module includes a first constraint member 21 constraining the end of the first plate 101 and a second constraint member 22 constraining the surface of the second plate 102. Simply put, both the first constraint member 21 and the second constraint member 22 are vertically oriented constraint plates. To facilitate the installation of the constraint plates, a mounting plate 24 extends horizontally from the lower edge of the constraint plates towards the non-constrained side. The mounting plate 24 is fixed to the platform 1, thereby achieving the fixed installation of the first constraint member 21 on the platform 1. To enhance the strength of the constraint plates and facilitate the coarse positioning of the range hood side panel 100 by compression, a reinforcing plate 25 connects the constraint plates and the mounting plate 24. Furthermore, to facilitate the insertion of the range hood side panel 100, the top of the constraint plates has a chamfer 23 guiding towards the constrained side; in this embodiment, the chamfer 23 is an arc-shaped chamfer 23.

[0022] Typically, the end of the first plate 101 will form a plane that can abut against the first constraint member 21 based on the guard plate 103. In this way, after the end of the first plate 101 can abut against the first constraint member, the extension direction of the first plate 101 is constrained, that is, the extension direction of the first plate 101 is constrained to be perpendicular to the surface of the first constraint member 21.

[0023] The second constraint member 22 is set in a parallel state to the first constraint member 21. The number of second constraint members 22 is determined based on the length of the second plate 102. The second plate 102 of the range hood side panel 100 is constrained inside the second constraint member 22. The second constraint member 22 forms a constraint on the second plate 102. After the range hood side panel 100 is placed within the constraint range of the first constraint member 21 and the second constraint member 22, the included angle between the first plate 101 and the second plate 102 can be adjusted to approximately 90° under the combined action of the first constraint member 21 and the second constraint member 22.

[0024] The precision positioning module 3 can accurately constrain the first plate 101 and the second plate 102 of the range hood side panel 100, so that the included angle between the first plate 101 and the second plate 102 reaches a precise 90° under the constraint of the precision positioning module 3. The precision positioning module 3 includes a first positioning component for forming a first positioning groove 301 for constraining the first plate 101 and a second positioning component for forming a second positioning groove 302 for constraining the second plate 102. The first positioning groove 301 and the second positioning groove 302 are at a 90° angle. When the first plate 101 is constrained in the first positioning groove 301 and the second plate 102 is constrained in the second positioning groove 302, the included angle between the first plate 101 and the second plate 102 is a precise 90°.

[0025] Specifically, the first positioning component includes at least two sets of constraint components distributed along the constraint direction of the first plate 101. Each set of positioning components includes a third constraint member 31 and a fourth constraint member 32 disposed opposite to each other. A gap matching the thickness of the first plate 101 is formed between the third constraint member 31 and the fourth constraint member 32. The gaps formed by the constraint components together form a first positioning groove 301 constraining the first plate 101. Since the second constraint member 22 has already constrained the outer side of the second plate 102, the second positioning component only needs to constrain the inner side of the second plate 102. The second positioning component includes at least two fifth constraint members 33 distributed along the constraint direction of the second plate 102. The fifth constraint members 33 are disposed facing the second constraint member 22. A gap matching the thickness of the second plate 102 is formed between each fifth constraint member 33 and the second constraint member 22. The gaps together form a second positioning groove 302 constraining the second plate 102.

[0026] Since the thickness of the side panels 100 of different range hoods may vary, in order to improve the applicability of this range hood side panel fixture, the third constraint member 31, the fourth constraint member 32, and the fifth constraint member 33 in this embodiment are all movably mounted on the platform 1.

[0027] Specifically, in order to facilitate the adjustment of the relative positional relationship between the third constraint member 31 and the fourth constraint member 32, the third constraint member 31 and the fourth constraint member 32 in each group of positioning members are movable on the platform 1 in a direction perpendicular to the constraint direction of the first plate 101.

[0028] In order to better guide the movement direction of the third constraint member 31 and the fourth constraint member 32, and thus ensure that the constraint direction of the third constraint member 31 and the fourth constraint member 32 remains unchanged, the platform 1 is provided with limiting grooves 11 corresponding to the movement direction and movement range of each third constraint member 31 and the fourth constraint member 32. The third constraint member 31 and the fourth constraint member 32 are set in the limiting grooves 11 and protrude from the upper surface of the platform 1.

[0029] In order to better adjust the gap between the fifth constraint member 33 and the second plate 102, the fifth constraint member 33 can be moved and installed on the platform 1 in a direction perpendicular to the constraint direction of the second plate 102. The platform 1 is provided with a limiting groove 11 corresponding to the moving direction and moving range of each fifth constraint member 33. The fifth constraint member 33 is installed in the limiting groove 11 and protrudes from the upper surface of the platform 1.

[0030] Before using the range hood side panel fixture, based on the range hood side panel, move the third constraint member 31, the fourth constraint member 32, and the fifth constraint member 33 into position according to their constraint positions, and then fix the third constraint member 31, the fourth constraint member 32, and the fifth constraint member 33 in their positions on the platform 1, and then adjust the 100° angle of the range hood side panel.

[0031] With the first positioning component roughly determining the basic vertical angle of the range hood side panel 100, as the range hood side panel 100 is pressed up and down onto the platform 1, the first plate 101 is pressed down into the first positioning groove 301, and at the same time the second plate 102 is pressed down into the second positioning groove 302. Thus, the first plate 101 and the second plate 102 are adjusted to a 90° angle based on the precision positioning module 3, and the range hood side panel 100 reaches the required angle.

[0032] The clamping module 4 includes a clamp 41 that can clamp the overlapping position of the first plate 101 and the second plate 102 and the guard plate 103. After the first plate 101 and the second plate 102 are adjusted to a 90° angle, the clamp 41 in the clamping module 4 is controlled to clamp the overlapping part of the guard plate 103 on the first plate 101 and the second plate 102, so that the gap between the overlapping part of the guard plate 103 on the first plate 101 and the second plate 102 is less than 0.1mm. Then the overlapping part of the guard plate 103 on the first plate 101 and the second plate 102 is welded, thus ensuring the stability of the 90° angle state of the range hood side panel 100.

[0033] The side panels of a range hood typically include a left side panel and a right side panel that are mirror-symmetrical. To enable simultaneous positioning and welding of both the left and right side panels, two sets of coarse positioning modules 2, fine positioning modules 3, and clamping modules 4 are arranged on platform 1 in a mirror-symmetrical manner. In this embodiment, to better demonstrate the structure of the components of the range hood side panel fixture and to illustrate the usage state of the range hood side panel 100 in conjunction with the range hood side panel fixture, [further details are needed]. Figure 1 The left side shows the working state of the range hood side panel 100 with the coarse positioning module 2, fine positioning module 3 and clamping module 4, while the right side shows the specific structure and distribution of the coarse positioning module 2, fine positioning module 3 and clamping module 4.

[0034] This range hood side panel fixture utilizes a coarse positioning module 2 to initially constrain the approximate angle of the side panel 100, and a fine positioning module 3 to achieve precise positioning of the side panel 100. This allows the side panel 100 to be precisely adjusted to a 90° angle. Then, a clamp 41 clamps the overlapping guard plates 103, ensuring the welding quality between the overlapping guard plates 103, ultimately producing a range hood side panel 100 with a stable 90° angle. This fixture solves the problems of low production efficiency and poor welding angles associated with manual welding, improving the production efficiency and product quality of the side panel 100, and facilitating subsequent assembly of the entire range hood.
