Description

Technical Field

[0001] This utility model belongs to the field of tapping machine technology, and in particular relates to a positioning device for a multi-axis tapping machine that processes multiple parts simultaneously. Background Technology

[0002] Tapping sheet metal parts is a crucial step in sheet metal fabrication. It involves machining internal threads into sheet metal parts to facilitate assembly with other components using bolts or similar methods. Tapping individual parts one by one is extremely inefficient. However, by using a multi-axis tapping machine with tapping fixtures to tap multiple parts simultaneously, efficiency can be significantly improved. If a part has multiple taps, a specialized device can be used to tap several taps at once or to process the tapping of several parts simultaneously on a multi-axis tapping machine.

[0003] Chinese patent document CN210306110U discloses a clamp for a tapping machine, including a base. A fixing component is provided on the upper end of the base. The fixing component includes fixing strips, each with a fixing groove on one side facing the other. A fixing plate is slidably connected between the two fixing grooves. One end of each fixing strip is connected to a limit strip, and the other end to a positioning strip. The limit strip has multiple limit holes, and the positioning strip has multiple positioning holes. The fixing plate has multiple first fixing holes on the side facing the limit plate, and multiple second fixing holes spaced apart along its length on the side facing the positioning plate. The fixing plate has first fixing holes that mate with the limit holes and second fixing holes that mate with the positioning holes on both sides. This allows the fixing plate to be moved towards the limit plate or the positioning plate according to the size of the workpiece, thus enabling the clamping of workpieces of different sizes, saving time and effort.

[0004] The aforementioned patented solution uses a fixing plate, a limiting plate, and a positioning plate to clamp the workpiece and achieve multi-axis tapping. However, it can only be applied to tapping "three-dimensional" parts. For tapping "planar" parts (such as sheet metal parts, thin plate parts, etc.), when applying the above patented solution, insufficient clamping force can cause the workpiece to loosen during the tapping process, reducing the tapping quality or even causing tapping failure. Excessive clamping force may bend the workpiece, and the clamping force on the workpiece may also cause the tapping hole to clamp the tap, accelerating the wear of the tap. Utility Model Content

[0005] To overcome the technical problems in existing technology where planar workpieces are difficult to clamp during multi-axis tapping, and where insufficient clamping force leads to loosening while excessive clamping force causes workpiece deformation, this utility model aims to provide a positioning device for a multi-axis tapping machine that simultaneously processes multiple parts. A positioning table is slidably connected to the machining table of the tapping machine, and a cover is slidably connected above the positioning table. The planar workpiece is placed between the positioning table and the cover, and is fixed by upper and lower clamping. A drill passes through a slot on the cover to perform tapping, and the cover also prevents the planar workpiece from moving upwards with the drill.

[0006] To achieve the above objectives, this utility model employs the following technical solution: a positioning device for a multi-axis tapping machine that simultaneously processes multiple parts, comprising a sliding plate slidably connected to the processing table of the tapping machine; a positioning table disposed on the upper end of the sliding plate; a groove disposed on the upper end of the positioning table, wherein there is at least one groove; and a through hole disposed on the groove, the through hole being located directly below the tapping position of the workpiece; wherein a cover is slidably connected to the sliding plate above the positioning table; the workpiece is placed between the groove and the cover; a through groove is provided through the cover, the through groove being selectively aligned with the corresponding through hole.

[0007] The workpiece is placed in the groove and fixed by the cover above; the drill passes through the through groove to tap the workpiece between the positioning table and the cover, and the cutting chips generated by tapping are partially discharged through the hole; as the drill moves upward, the cover can also prevent the workpiece from moving upward.

[0008] Furthermore, an anti-misbehavior plate is provided at the upper end of the groove; the end of the anti-misbehavior plate facing the adjacent workpiece fits and abuts against the outer wall of the adjacent workpiece.

[0009] Optionally, the shape of the groove is the same as the bottom profile of the workpiece.

[0010] Optionally, the lower end of the workpiece is provided with an extension; the groove is an insertion slot directly opposite the extension.

[0011] Furthermore, the positioning platform has a hollow cavity structure inside; a gasket is provided on the sliding plate to abut against the top of the cavity structure; a screw is provided on the upper end of the positioning platform, passing through the gasket, and the screw is tightened on the upper end of the sliding plate.

[0012] Specifically, the cover is an inverted U-shaped sheet metal structure; the positioning platform is located inside the opening of the U-shaped sheet metal structure; a folded edge is provided at one end of the cover near the positioning platform; a handle is provided at the one end of the cover away from the positioning platform; an opening groove is provided on the folded edge, and the screw is located in the opening groove.

[0013] Specifically, the inner top of the cover is provided with a plurality of stamped ribs, the length direction of which is arranged along the sliding direction of the cover; the lower end of the stamped ribs abuts against the upper end of the positioning platform.

[0014] The cover and positioning table are replaced according to the different parts being processed. The cover and positioning table are simple to process, low in cost, and easy to replace, which reduces the cost of molds.

[0015] Furthermore, the upper end of the positioning platform is provided with two columns; the cover is provided with two guide grooves that are slidably connected to the columns respectively.

[0016] Furthermore, a base plate is provided on the upper end of the processing table; two tracks are symmetrically arranged on the base plate; and two sliding seats are provided at the lower end of the sliding plate, which are respectively slidably connected to the two tracks.

[0017] Preferably, the positioning platform is an inverted box-shaped sheet metal structure; the gasket has multiple layers stacked together.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model enables the tapping machine to process multiple parts at once or perform multiple taps at once, improving processing efficiency and solving the problem of slow efficiency for single tapping, making it suitable for mass production.

[0020] 2. This utility model uses a positioning table and a cover to clamp a flat workpiece between the two from the top and bottom. It can position the workpiece without controlling the clamping force and prevent the flat workpiece from deforming. The cover can also prevent the workpiece from moving upward with the drill, ensuring the tapping quality.

[0021] 3. This utility model adopts corresponding positioning tables and covers according to different workpieces. Both the positioning tables and covers are made of sheet metal, which makes the processing simple and the cost low, thereby reducing the processing cost of the workpieces.

[0022] 4. This utility model also includes a sliding plate, which allows the positioning table to slide out from under the drill bit before the workpiece is picked up or placed on the positioning table, facilitating manual operation. It also prevents accidental collisions with the drill bit during manual operation, ensuring personal safety while also guaranteeing the accuracy of the tap on the drill bit.
