A stepped screw positioning and drilling device

Abstract

This application provides a stepped screw positioning and drilling device, relating to the field of stepped drilling devices. It includes a support plate with a limiting groove on its upper surface. A bidirectional threaded rod is rotatably connected inside the support plate, and a first rotating disk is fixedly connected to one end of the bidirectional threaded rod. A clamping block is slidably connected inside the limiting groove. In use, the four clamping blocks quickly clamp the workpiece, and rotating the second rotating disk brings the strong magnetic block into contact with the lower surface of the first magnetic guide block. The magnetism of the strong magnetic block is conducted to the support plate through the first magnetic guide block, causing the workpiece to be firmly attached to the surface of the support plate, thus maintaining its position during processing. After one part is processed, rotating the second rotating disk separates the strong magnetic block from the first magnetic guide block and allows it to engage with the second magnetic guide block, releasing the strong magnetic block from the workpiece. This allows for quick installation and removal of parts, improving production efficiency.

Description

Technical Field

[0002] Stepped screws are widely used in mechanical manufacturing and various industrial production processes. Their installation accuracy directly affects the performance and stability of the entire product or structure. Precise positioning and drilling are crucial steps in the installation of stepped screws. Even a slight deviation in the drilling position can prevent the screw from being properly assembled, leading to a series of serious problems such as loose connections and structural instability.

[0003] However, existing technologies require the parts to be drilled to be fixed to the workbench with bolts or other means, which requires workers to spend a lot of time positioning and fixing the parts, greatly reducing work efficiency. Therefore, a stepped screw positioning and drilling device was proposed. Utility Model Content

The outer surface of the clamping block is slidably connected to the inner surface of the limiting groove. The inner surface of the clamping block is slidably connected to the outer surface of the bidirectional threaded rod. One end of the transmission block is in contact with one side of the clamping block. A fixed box is fixedly connected to the lower surface of the support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this application's solution: during use, the distance between the four clamping blocks is first moved to be slightly smaller than the distance to the workpiece to be processed, so as to facilitate clamping the workpiece. Then, the workpiece is pressed into the space between the four clamping blocks, so that the workpiece contacts the inclined surface of the upper surface of the clamping blocks. The four clamping blocks are moved in all directions, and the springs are compressed, fixing the workpiece in the middle position. Then, the second rotating disk is rotated, so that the strong magnetic block contacts the lower surface of the first magnetic block. The magnetism of the strong magnetic block is conducted to the support plate through the first magnetic block, so that the workpiece is firmly attached to the surface of the support plate. This ensures that the workpiece remains in a fixed position during processing, guaranteeing the processing accuracy of the workpiece. After a part is processed, the second rotating disk is rotated, so that the strong magnetic block separates from the first magnetic block and attaches to the second magnetic block, releasing the strong magnetic block from the workpiece. This allows for quick installation and removal of parts, enabling rapid processing and improving production efficiency. Attached Figure Description

[0025] Furthermore, such as Figure 1 , Figure 3 As shown, a limiting ring 22 is fixedly connected to the upper surface of the support plate 1. An electric telescopic rod 6 is rotatably connected inside the limiting ring 22. The electric telescopic rod 6 is used to facilitate changing the height of the drill bit 20.

[0026] Furthermore, such as Figure 1 , Figure 3 As shown, the output end of the electric telescopic rod 6 is fixedly connected to a fixing frame 11. The upper surface of the fixing frame 11 is provided with a sliding groove 21, which serves to limit the position of the slider 18.

[0030] The usage process of the stepped screw positioning and drilling device provided by this utility model is as follows: First, rotate the first rotating disk 3, causing it to drive the bidirectional threaded rod 4 to rotate. Utilizing the threaded transmission between the bidirectional threaded rod 4 and the two transmission blocks 10, the two transmission blocks 10 move towards both ends of the bidirectional threaded rod 4, moving the distance between the two clamping blocks 5 to a distance slightly smaller than the distance to the workpiece to be processed. Then, rotate the other first rotating disk 3, moving all four clamping blocks 5 to a distance slightly smaller than the distance to the workpiece to be processed, facilitating workpiece clamping. Next, press the workpiece between the four clamping blocks 5, making the workpiece contact the inclined surface of the upper surface of the clamping blocks 5, causing the four clamping blocks 5 to move outwards and compress the spring 9, fixing the workpiece in the middle position. Then, rotate the second rotating disk 7, causing the strong magnetic block 14 to contact the lower surface of the first magnetically conductive block 13, making the magnetic force of the strong magnetic block 14... The magnetic force is transmitted to the support plate 1 through the first magnetic block 13, so that the workpiece is stably attached to the surface of the support plate 1. This ensures that the workpiece remains in a fixed position during processing. Then, the fixed frame 11 is rotated and the first motor 16 is started, which drives the transmission threaded rod 17 to rotate. The transmission threaded rod 17 and the slider 18 are connected by a threaded transmission. The slider 18 is adjusted to move the drill bit 20 and the second motor 19, so that the limiting groove 2 reaches the position where the part needs to be drilled. Then, the electric telescopic rod 6 is started, which moves the drill bit 20 up and down to drill holes in the device. After one part is processed, the second rotating disk 7 is rotated, which separates the strong magnetic block 14 from the first magnetic block 13 and puts it into contact with the second magnetic block 15. This releases the strong magnetic block 14 from the workpiece, and the part is removed. Then, the next part can be quickly inserted, realizing rapid processing.
