Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a tooling for drilling holes in sheet metal. Background Technology

[0002] As the most basic component in mechanical equipment, sheet metal is often processed to facilitate use. For example, in braking equipment, multiple rows of mounting holes are machined at equal intervals along the circumference of a semi-circular sheet metal. In existing technology, when drilling holes in a semi-circular sheet metal, it is usually placed in a rotating fixture. After one row of mounting holes is machined, the fixture is usually rotated by a predetermined angle. However, due to the weight of the sheet metal, rotation is laborious, and existing fixtures can usually only accommodate one or a limited number of sheet metal sizes. Although this facilitates the limiting of sheet metal movement, it has poor versatility and cannot adapt to a wider range of sheet metal sizes, leading to increased equipment costs. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a tooling for drilling plates, which can adapt to plates of different sizes, is more convenient to operate, has higher versatility, saves costs, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology: A tooling for drilling holes in sheet metal includes: a worktable and a limit component.

[0005] The top surface of the workbench has multiple spaced support plates arranged circumferentially and movable vertically. The top surface of each support plate has multiple balls that rotate around their own center along their length to lift the plate. When the support plate is at its lowest point of travel, the balls are below the top surface of the workbench. The limiting assembly includes a rotating plate rotatably mounted on the workbench. On one side of the rotating plate are two symmetrically arranged support plates that move towards each other. Limiting wheels are rotatably mounted at the ends of the support plates. In application, one side of the plate abuts against the side of the rotating plate, and the limiting wheels contact the arc-shaped surface of the plate.

[0006] Furthermore, the workbench is provided with an elongated hole located between two support plates, and a drilling device is provided above the elongated hole for the drill rod of the drilling device to pass through.

[0007] Furthermore, the top surface of the workbench is provided with multiple through slots running vertically along the circumference. The support plate is located in the through slots and is installed on the lifting plate. The lifting plate is located below the workbench and is connected to the moving end of the vertical lifting mechanism, which is installed below the workbench.

[0008] Furthermore, the rotating plate has two grooves located at its two ends on its side. The support plate passes through the grooves and is respectively fitted onto the two opposite threads of the bidirectional screw. The bidirectional screw is rotatably mounted on the protrusion and locked with a nut. The protrusion is mounted on the other side of the rotating plate.

[0009] Furthermore, a vertically arranged positioning rod is inserted through one end of the rotating plate. The lower end of the positioning rod is inserted into the worktable, and the upper end is inserted into the bracket. The bracket is installed in the rotating plate. A retaining ring is provided on the positioning rod, and a spring is sleeved on the positioning rod. The two ends of the spring abut against the bracket and the retaining ring respectively, and are always in a compressed state.

[0010] Furthermore, the top surface of the workbench is provided with multiple positioning blocks and multiple threaded holes along the circumferential direction. The positioning blocks are connected to a threaded hole through studs. A horizontally arranged arc-shaped plate is passed through one end of the rotating plate and locked with screws. A positioning pin is passed through one end of the arc-shaped plate. In application, the lower end of the positioning pin is inserted into one of the positioning blocks.

[0011] Furthermore, grooves are provided on the bottom surfaces of both ends of the rotating plate for the support plate to pass through.

[0012] The advantages of this utility model are as follows: the rotating plate and two limiting wheels limit the periphery of the plate, thereby adapting to plates of different sizes, increasing versatility and saving tooling costs; when rotating the plate, the ball bearings lift the plate, replacing sliding friction with rolling friction, making the rotation process smoother and less labor-intensive; and the positions of the positioning pin and positioning block can be adjusted to adapt to different rotation angles of the plate, further improving versatility.

[0017] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1-3 As shown, this example provides a tooling for drilling plates, including: a worktable 100 and a limiting component 200.

[0019] The top surface of the workbench 100 has multiple spaced support plates 101 arranged circumferentially and movable vertically. The top surface of each support plate 101 has multiple balls 102 rotating around their own centers along its length, used to lift the workpiece. When the workpiece rotates, the balls 102 also rotate, creating rolling friction between the workpiece and the balls 102, making the rotation smoother. Furthermore, when the support plate 101 is at its lowest point, the balls 102 are below the top surface of the workbench 100, allowing the workpiece to be placed smoothly on the workbench. On the workbench 100, to prevent the board from warping during drilling, the limiting component 200 includes a rotating plate 201 rotatably mounted on the workbench 100. Two symmetrically arranged and opposing support plates 202 are provided on one side of the rotating plate 201. Limiting wheels 203 are rotatably mounted on the ends of the support plates 202. When the board is placed on the workbench 100, one side of the board abuts against the side of the rotating plate 201, and the limiting wheel 203 contacts the arc surface of the board, thereby limiting the circumference of the board and preventing the board from shifting.

[0020] Specifically, the workbench 100 is provided with an elongated hole 103, which is located between two support plates 101. A drilling device is provided above the elongated hole 103 for the drill rod of the drilling device to pass through. When drilling, the position of the plate to be drilled is rotated to be directly above the elongated hole 103, and then the drilling device is used to drill the plate.

[0021] Specifically, the top surface of the workbench 100 is provided with multiple through slots 104 running vertically along the circumference. The support plate 101 is located in the through slots 104 and is installed on the lifting plate. The lifting plate is located below the workbench 100 and is connected to the moving end of the vertical lifting mechanism. The vertical lifting mechanism is installed below the workbench 100 and can adopt a telescopic cylinder or a motor screw structure. When it is necessary to rotate the plate, the vertical lifting mechanism drives the lifting plate to move upward, so that the ball bearings 102 lift the plate. Then the rotating plate 201 is rotated, and the plate will rotate synchronously. After the plate rotates to the predetermined position, the lifting plate is moved downward, and the ball bearings 102 will be lower than the top surface of the workbench 100, and the plate will contact the workbench 100.

[0022] Specifically, the rotating plate 201 has two grooves 204 located at its two ends on its side. The support plate 202 passes through the groove 204 and is respectively fitted onto the two opposite threads of the bidirectional screw 205. The bidirectional screw 205 is rotatably mounted on the protrusion 206 and locked with a nut. The protrusion 206 is mounted on the other side of the rotating plate 201. When it is necessary to adapt to different materials, the nut is loosened and the bidirectional screw 205 is rotated, so that the two support plates 202 can move synchronously towards each other or move away from each other. Then the nut is used to lock the bidirectional screw 205, thereby adapting to materials of different sizes.

[0023] Specifically, a vertically arranged positioning rod 207 is inserted through one end of the rotating plate 201. The lower end of the positioning rod 207 is inserted into the worktable 100, and the upper end is inserted into the bracket 208. The bracket 208 is installed in the rotating plate 201. A retaining ring 209 is provided on the positioning rod 207, and a spring 210 is sleeved on the positioning rod 207. The two ends of the spring 210 abut against the bracket 208 and the retaining ring 209 respectively, and are always in a compressed state. Under the action of the spring 210, the positioning rod 207 always has a downward tendency, ensuring that the positioning rod 207 can be stably inserted into the worktable 100, so that the rotating plate 201 can be fixed in the initial position. This allows the rotation angle to be adjusted in time after the plate is placed in the initial position. When it is necessary to rotate the rotating plate 201, the lower end of the positioning rod 207 is removed from the worktable 100 to release the positioning.

[0024] Specifically, the top surface of the workbench 100 is provided with multiple positioning blocks 105 and multiple threaded holes 106 along the circumferential direction. The number of threaded holes 106 is much greater than the number of positioning blocks 105. Each positioning block 105 is connected to a threaded hole 106 by a stud, so that the position of the positioning block 105 can be changed according to the rotation angle of the plate to adapt to different processing requirements. One end of the rotating plate 201 is provided with a horizontally arranged arc plate 211 and locked with screws. One end of the arc plate 211 is provided with a positioning pin 212. When the plate rotates to the predetermined position, the lower end of the positioning pin 212 is inserted into one of the positioning blocks 105. When the plate rotates, the positioning pin 212 is removed from the positioning block 105. After the plate rotates to the predetermined position, the positioning pin 212 is re-inserted into another positioning block 105.

[0025] Specifically, the bottom surfaces at both ends of the rotating plate 201 are provided with grooves for the support plate 101 to pass through, so as to avoid interference between the rotating plate 201 and the support plate 101 during the rotation of the rotating plate 201.

[0026] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
