Description

Technical Field

[0001] This utility model belongs to the field of audio equipment manufacturing technology, and in particular relates to a drilling device for the production and processing of audio equipment grilles. Background Technology

[0002] A speaker grille is a protective device for audio equipment, shielding the speaker from impacts, dust, and other environmental factors. It is typically used to cover the speaker section of an audio device and is usually made of metal or plastic. It is designed with a porous structure to allow sound to pass through smoothly. Because of its porous structure, a perforation machine is required to punch holes in the speaker grille during its production.

[0003] However, existing technologies have the following shortcomings:

[0004] 1. Existing technology achieves the drilling of speaker grilles by passing a punch through the grille to be drilled. However, after drilling, since the punch is inserted into the inside of the speaker grille, the punch and the speaker grille are in contact. There is a certain friction between the speaker grille and the punch in the contact state. This friction causes the speaker grille to move when the punch moves. Therefore, it is necessary to manually operate the speaker grille to detach from the punch, which is not only cumbersome, but also poses a safety hazard.

[0005] 2. In the existing technology, before punching holes in the speaker grille, the speaker grille to be punched needs to be placed in a suitable position on the worktable below the punch. However, during the placement process, the placement position often shifts or tilts horizontally, resulting in the speaker grille not meeting production requirements and being scrapped after punching. Utility Model Content

[0006] The purpose of this utility model is to provide a drilling device for the production and processing of speaker grilles. An elastic element applies force to a moving plate, causing the moving plate to move the speaker grille and detach it from the punch. Furthermore, the positioning plate and positioning strip work together to position the speaker grille. This solves the problem of existing technologies requiring manual operation to detach the speaker grille from the punch during drilling, which is not only cumbersome but also poses safety hazards. Additionally, during the placement of the speaker grille to be drilled, misalignment or horizontal tilting often occurs, resulting in the drilled speaker grille failing to meet production requirements and being scrapped.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a drilling device for the production and processing of speaker grilles. It includes a worktable, a support plate fixed to the upper wall of the worktable, a movable plate above the support plate, and a mounting plate above the movable plate. Punches are evenly fixed to the lower wall of the mounting plate, and through holes are formed on the movable plate corresponding to the positions of the punches. Elastic elements are evenly arranged along the edge of the upper wall of the movable plate, and a protruding plate is fixed to the upper end of each elastic element, with the protruding plate fixedly connected to the movable plate. A positioning strip is fixed to the rear side of the upper wall of the support plate, and positioning plates are symmetrically arranged on the left and right sides of the upper wall of the support plate. A dual-head motor is located below the worktable, and screws are fixed to the power output shaft of the dual-head motor. The screws are threadedly connected to the positioning plates, with the threads of the two screws in opposite directions.

[0009] The present invention is further configured such that a cylinder is fixed at the middle position of the upper wall of the mounting plate, a mounting bracket is fixed at the rear end of the worktable, and the upper end of the cylinder is fixedly connected to the mounting bracket.

[0010] The present invention is further configured such that guide rods are fixed at the four corner positions of the upper wall of the mounting plate, and guide sleeves are provided on the outer gap of the guide rods, with the upper end of the guide sleeves fixedly connected to the mounting frame.

[0011] The present invention is further configured such that the positioning plate is L-shaped, and a limit rod is provided on the outer side wall of the positioning plate with clearance fit, and the inner end of the limit rod is fixedly connected to the worktable.

[0012] The present invention is further configured such that a rectangular groove is provided on the inner side of the workbench, and a connecting plate is fixed on the workbench below the rectangular groove, and the dual-head motor is fixedly connected to the connecting plate.

[0013] The present invention is further provided that each of the four corner positions of the lower wall of the workbench is fixed with a support leg.

[0014] The present invention is further configured such that a collection box is provided below the rectangular groove, the collection box is inclined, and vertical rods are fixed at the four corners of the lower wall of the collection box, with casters fixed at the lower ends of the vertical rods.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting an elastic element and a movable plate, allows the movable plate to move upwards when the punch moves upwards. Because the elastic element applies a downward supporting force to the movable plate, when this supporting force is greater than the frictional force between the speaker grille and the punch, the movable plate and the mounting plate move away from each other, causing the speaker grille to detach from the punch. Compared with the prior art, the cooperation of the elastic element and the movable plate allows the speaker grille to detach from the punch without manual operation, making the drilling of the speaker grille simpler. Furthermore, the elimination of manual operation reduces safety hazards during operation, solving the problem that the prior art requires manual operation to detach the speaker grille from the punch during drilling, which is not only cumbersome but also poses safety risks.

[0017] 2. This utility model uses positioning strips, positioning plates, a dual-head motor, and a screw. The positioning strips position the rear end of the speaker grille to be perforated. The dual-head motor drives the screw to rotate, causing the positioning plates to move closer together until the inner sidewalls of the two positioning plates abut against the speaker grille to be perforated. This positions the speaker grille accordingly. Compared with existing technologies, the cooperation of the positioning plates and positioning strips avoids placement misalignment or horizontal tilting, solving the problem that frequent placement misalignment or horizontal tilting of speaker grilles during placement, which often leads to the perforated speaker grilles failing to meet production requirements and being scrapped.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Please see Figure 1-3 This utility model is a drilling device for the production and processing of speaker grilles. It includes a workbench 4, a support plate 6 fixed on the upper wall of the workbench 4, and the support plate 6 is detachably fixed to the workbench 4 to facilitate replacement of the support plate 6. A movable plate 3 is provided above the support plate 6, and an mounting plate 2 is provided above the movable plate 3. Punches 203 are uniformly fixed on the lower wall of the mounting plate 2. The punches 203 are detachably fixed to the mounting plate 2. A through hole 302 is opened on the movable plate 3 at the position of the punch 203. The through hole 302 is adapted to the punch 203 and the punch 203 can be inserted into the through hole 302. Elastic members 301 are uniformly provided along the edge of the upper wall of the movable plate 3 to apply a downward force to the movable plate 3. This force is greater than the friction between the speaker grille and the punch 203. A protruding plate 202 is fixed at the upper end of the elastic member 301 and is fixedly connected to the movable plate 3.

[0029] Specifically, a cylinder 1 is fixed at the middle position of the upper wall of the mounting plate 2 to provide power for the mounting plate 2 to move upward and downward. A mounting bracket 401 is fixed at the rear end of the worktable 4, and the upper end of the cylinder 1 is fixedly connected to the mounting bracket 401.

[0030] Guide rods 201 are fixed at the four corners of the upper wall of the mounting plate 2. Guide sleeves 401a are provided on the outside of the guide rods 201 with clearance fit. The upper end of the guide sleeves 401a is fixedly connected to the mounting bracket 401. With the above arrangement, the cooperation between the guide sleeves 401a and the guide rods 201 can prevent the mounting plate 2 from tilting.

[0031] The operation process of this embodiment is as follows: When punching holes in the speaker grille, the free end of the cylinder 1 is extended to drive the mounting plate 2 to move downward, thereby driving the punch 203 and the moving plate 3 to move downward until the moving plate 3 contacts the speaker grille to be punched. Then, the free end of the cylinder 1 is extended until the punch 203 passes through the speaker grille to be punched and is inserted into the through hole 601. Then, the free end of the cylinder 1 is retracted. Then, under the action of the elastic member 301, the moving plate 3 moves downward, pushing the speaker grille to detach from the punch 203.

[0032] Example 2

[0033] Please see Figure 1 , 4 5. This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a positioning strip 602 is fixed on the rear side of the upper wall of the support plate 6, and positioning plates 7 are symmetrically arranged on the left and right sides of the upper wall of the support plate 6. The cooperation between the positioning strip 602 and the positioning plates 7 realizes the positioning of the speaker grille to be drilled. A double-head motor 8 is arranged below the workbench 4. A screw 801 is fixed on the power output shaft of the double-head motor 8. The screw 801 is threadedly connected to the positioning plate 7. The threads of the two screws 801 are opposite, so that when the double-head motor 8 works, it drives the screw 801 to rotate, thereby driving the two positioning plates 7 to move closer or further away from each other.

[0034] Specifically, the positioning plate 7 is L-shaped, and a limit rod 403 is provided on the outer side wall of the positioning plate 7 with a gap fit to provide guidance for the positioning plate 7 and prevent the positioning plate 7 from rotating when the screw 801 rotates, thus preventing it from being unable to move. The inner end of the limit rod 403 is fixedly connected to the worktable 4.

[0035] A rectangular groove 404 is provided on the inner side of the workbench 4, so that the waste material after drilling can pass through and enter the collection box 5. A connecting plate 405 is fixed on the workbench 4 below the rectangular groove 404, and the double-head motor 8 is fixedly connected to the connecting plate 405.

[0036] Support legs 402 are fixed at the four corners of the lower wall of the workbench 4 to support the workbench 4.

[0037] A collection box 5 is provided below the rectangular groove 404 for collecting drilling waste. The collection box 5 is tilted so that the drilling waste automatically moves to the lower part of the collection box 5, making it easier to clean the drilling waste in the collection box 5. Vertical rods 501 are fixed at the four corners of the lower wall of the collection box 5, and casters 501a are fixed at the lower end of the vertical rods 501 to make the collection box 5 easy to move.

[0038] The remaining structure is the same as in Example 1;

[0039] The operation process of this embodiment is as follows: Before drilling, the speaker grille to be drilled is placed on the upper surface of the support plate 6, and the rear wall of the speaker grille to be drilled is made to abut against the positioning strip 602. Then, the dual-head motor 8 is controlled to drive the screw 801 to rotate, so that the screw 801 drives the two positioning plates 7 to move closer to each other until the inner side wall of the positioning plate 7 contacts the speaker grille to be drilled, thus completing the positioning of the speaker grille to be drilled. After the positioning is completed, the dual-head motor 8 is controlled to move the two positioning plates 7 away from each other, and then the cylinder 1 is controlled to perform the drilling operation.

[0040] When it is necessary to clean the perforated waste in the collection box 5, a forward force is applied to the collection box 5, and the collection box 5 moves forward under the action of the caster wheel 501a to facilitate the cleaning operation.
