Description

Technical Field

[0001] This utility model relates to the field of machining equipment, specifically a coupling multi-station extrusion tapping machine. Background Technology

[0002] Slender rods are typically connected by couplings, such as sucker rods. The inner hole of the coupling needs to be tapped; tapping is a metalworking process used to create internal threads on a workpiece. In existing coupling tapping processes, the coupling workpiece is manually placed on a tapping machine, and after tapping, it is also manually removed. Furthermore, one tapping machine taps one workpiece at a time, resulting in significant time wasted on placing and removing workpieces, leading to low production efficiency. Utility Model Content

[0003] To address the problems of existing technologies, this invention provides a multi-station extrusion tapping machine for couplings. The tapping head can process multiple coupling workpieces in a single feed, resulting in high processing efficiency. Furthermore, it features multiple stations, allowing the tapped workpieces and the tapped material to be moved to a cooling station for cooling.

[0004] This utility model includes a tapping device, a workpiece holder, a clamping device, and a workpiece lifting device. The workpiece holder includes a machining station and a cooling station. The machining station has a through-hole structure. The workpiece lifting device lifts several vertically arranged workpieces from below the workpiece holder and through the through-hole. The tapping device taps the inner hole of the workpiece from top to bottom. During operation, the inner hole of the workpiece, the through hole of the workpiece holder, and the tapping device are located on the same axis. The tapping device includes a tapping seat and a tap, with the tapping head and the tap being movably connected. The tapping head is connected to a rotary drive device and a vertical displacement drive device. The workpiece holder is connected to a horizontal displacement device. The clamping device includes a clamping cylinder and several clamps, which are distributed on both sides of the workpiece above the workpiece holder.

[0005] In a further improvement, the tapping head has a square groove at the bottom and a square structure at the top that matches the directional groove. The top of the tapping head is inserted into the square groove, making it easy to replace the tapping head after it wears out.

[0006] In a further improvement, the horizontal displacement device consists of a servo motor and a lead screw. The servo motor drives the lead screw to actively control the horizontal displacement of the slider on the lead screw, and the slider is fixedly connected to the workpiece seat.

[0007] In a further improvement, the rotary drive device includes a tapping motor, a reducer, a synchronous belt, and a driven gear connected in sequence. The driven gear has a spline in the center, and the spline is connected to the tapping head.

[0008] In a further improvement, the vertical displacement driving device includes a vertical slide rail and a vertical slider that slides along the vertical slide rail under the control of a tapping cylinder, and the vertical slider is connected to the tapping head.

[0009] The working process of this utility model is as follows:

[0010] The workpiece holder moves the machining station below the tapping station. The lifting device sequentially lifts several workpieces from below the machining station, passes them through the station, and clamps them using a clamping device. The tapping head rotates while simultaneously feeding downwards, machining all workpieces in a straight line in one pass. After machining, the tapping head rises, the workpiece holder moves, moving the cooling station below the workpieces. The clamping device releases, and the machined workpieces and taps fall onto the outermost cooling station. The workpiece holder moves again, a new tap is replaced, and the above steps are repeated to machine the remaining workpieces. Once the cooling station is full, all cooled workpieces are collected from the cooling stations at once.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The tapping head can process multiple coupling workpieces in one feed, resulting in high processing efficiency.

[0013] 2. Furthermore, there are multiple workstations. The workpiece holder moves horizontally to switch workstations, and the tapped workpiece can be moved to the cooling workstation for cooling. Attached Figure Description
