Description

Technical Field

[0001] This application relates to the field of drill rod processing technology, specifically a drill rod connecting sleeve production device. Background Technology

[0002] As a key connecting component of the drilling tool system in mining, tunneling, and other engineering projects, the core structure of the drill rod connecting sleeve is a cylindrical body, which requires high-precision threads to be machined on its inner wall to meet the requirements of high-strength power transmission. With the popularization of large-scale engineering equipment, the market has placed higher demands on the mass production capacity of drill rod connecting sleeves.

[0003] Currently, most mainstream production processes employ a single-station machining mode: a single connecting sleeve workpiece is clamped and positioned using a chuck or fixture, and after the internal thread is machined using a lathe or dedicated tapping equipment, it needs to be manually unloaded and re-clamped for the next workpiece. This mode has significant drawbacks:

[0004] Low processing efficiency: Only one workpiece can be processed in a single clamping. Frequent clamping-unloading-re-clamping processes significantly shorten the effective working time of the equipment and limit the unit capacity. At the same time, each workpiece requires manual intervention for clamping and positioning, which is not only labor-intensive but also prone to affecting the consistency of processing due to differences in operation. Utility Model Content

[0005] This application provides a drill rod connecting sleeve production device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a drill rod connecting sleeve production device, comprising a base; an equipment box is installed in the middle of the upper surface of the base, a sleeve that can be rotatably connected is provided on the inner side of the equipment box, a hollow multi-faceted rod is slidably connected to the inner side of the sleeve, a turntable is fixedly connected to the upper end face of the hollow multi-faceted rod, a hydraulic telescopic rod II is provided inside the hollow multi-faceted rod, the upper end face of the hydraulic telescopic rod II is rotatably connected to the lower surface of the turntable through a bearing, the lower end face of the hydraulic telescopic rod II passes through the sleeve and is fixedly installed at the bottom of the inner side of the equipment box, and a power mechanism for controlling the rotation of the sleeve is provided inside the equipment box.

[0007] A ring-shaped support platform is provided below the turntable. The lower surface of the ring-shaped support platform is connected to the upper surface of the base through the main support rod. Positioning through holes are evenly distributed in a ring array on the edge of the upper surface of the turntable. A hydraulic telescopic rod is installed on the outer side of the base. The telescopic end of the hydraulic telescopic rod is connected to a hydraulic three-jaw chuck through a connecting frame.

[0008] Preferably, the lower end face of the sleeve is rotatably connected to the bottom of the inner side of the equipment box via a bearing.

[0009] Preferably, the power mechanism includes a stepper motor installed inside the equipment box, with a first gear mounted on the output shaft of the stepper motor, and a second gear meshing with the first gear mounted on the outer side of the sleeve.

[0010] Preferably, the upper surface of the annular support platform is provided with a discharge port at the front end.

[0011] Preferably, a strip rubber plate is installed on the lower surface of the turntable.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] 1. This application, through the design of positioning through holes in the annular array on the edge of the turntable, combined with the alternating clamping action of the hydraulic three-jaw chuck, can load multiple chisel connecting sleeve workpieces at one time; during the process of the stepper motor driving the sleeve to drive the turntable to rotate indexing, the hydraulic telescopic rod pushes the chuck to move laterally to the processing station, realizing the simultaneous operation of multiple processes of "processing-clamping-unloading", breaking through the limitation of single-piece processing, and improving the equipment utilization rate.

[0014] 2. The turntable is raised and positioned by the hydraulic telescopic rod II, and the stepper motor accurately indexes the workpiece through the meshing transmission of gear I and gear II. The hydraulic three-jaw chuck automatically clamps the workpiece. Combined with the centralized power mechanism in the equipment box, the entire process of clamping, rotating, processing and unloading is automated.

[0015] 3. A dedicated unloading port is set at the front end of the ring support platform. When the finished workpiece is rotated to this station with the turntable, it will automatically fall off by its own weight or auxiliary mechanism without stopping the machine to unload. Combined with the anti-deflection design of the hollow multi-faceted rod, it ensures that the workpiece remains stable during high-speed rotation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Figure 2 The orientations or positional relationships shown are for the convenience of describing this application and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] Please see Figure 1-2 This application provides the following technical solution: a drill rod connecting sleeve production device, including a base 6; an equipment box 5 is installed in the middle of the upper surface of the base 6, a sleeve 16 that can be rotatably connected is provided on the inner side of the equipment box 5, a hollow multi-faceted rod 12 is slidably connected to the inner side of the sleeve 16, a turntable 3 is fixedly connected to the upper end face of the hollow multi-faceted rod 12, a hydraulic telescopic rod 14 is provided inside the hollow multi-faceted rod 12, the upper end face of the hydraulic telescopic rod 14 is rotatably connected to the lower surface of the turntable 3 through a bearing, the lower end face of the hydraulic telescopic rod 14 passes through the sleeve 16 and is fixedly installed at the bottom of the inner side of the equipment box 5, and a power mechanism for controlling the rotation of the sleeve 16 is provided inside the equipment box 5.

[0022] Specifically, the hollow multi-faceted rod 12 has a polygonal cross-section, and the hydraulic telescopic rod 14 can control the lifting and lowering of the turntable 3 by telescoping. The power mechanism is used to drive the turntable 3 to rotate.

[0023] A ring support platform 11 is provided below the turntable 3. The lower surface of the ring support platform 11 is connected to the upper surface of the base 6 through the main support rod 7. The upper surface of the turntable 3 is evenly distributed with positioning through holes 2 in a ring array along its edge. A hydraulic telescopic rod 8 is installed on the outer side of the base 6. The telescopic end of the hydraulic telescopic rod 8 is connected to a hydraulic three-jaw chuck 1 through a connecting frame 9.

[0024] Specifically, the drill rod connecting sleeve requiring internal machining is placed into the positioning through hole 2. As the turntable 3 rotates, the connecting sleeve is conveyed to the position directly below the hydraulic three-jaw chuck 1. The hydraulic three-jaw chuck 1 then moves downwards to clamp and position the connecting sleeve. After positioning, internal machining can proceed. The diameter of the positioning through hole 2 is slightly larger than the diameter of the connecting sleeve.

[0025] Furthermore, the lower end face of the sleeve 16 is rotatably connected to the bottom of the inner side of the equipment box 5 via a bearing.

[0026] Furthermore, the power mechanism includes a stepper motor 13 installed inside the equipment box 5, a gear 17 mounted on the output shaft of the stepper motor 13, and a gear 15 that meshes with the gear 17 mounted on the outer side of the sleeve 16.

[0027] Specifically, the stepper motor 13 can drive the turntable 3 to rotate through the gear transmission mechanism.

[0028] Furthermore, a discharge port 4 is provided at the front end of the upper surface of the annular support platform 11.

[0029] Specifically, the setting of the feed port 4 facilitates the automatic unloading of the drill rod connecting sleeve after processing.

[0030] Furthermore, a strip rubber plate 10 is installed on the lower surface of the turntable 3.

[0031] Specifically, after the lower surface of the strip rubber plate 10 contacts the upper surface of the annular support platform 11, the turntable 3 drives the strip rubber plate 10 to rotate, which can clean the debris on the upper surface of the annular support platform 11.

[0032] In use: Place the workpieces to be processed, such as the drill rod connecting sleeves, into the positioning through holes 2 on the edge of the turntable 3 in sequence. The bottom of the workpieces is supported by the annular support platform 11. The annular array of positioning through holes 2 on the turntable 3 can accommodate multiple workpieces at the same time.

[0033] When the equipment is started, the stepper motor 13 drives the sleeve 16 to rotate through the meshing of gear 17 and gear 2 15, which in turn drives the hollow multi-faceted rod 12 and the turntable 3 to rotate in sections, so that the first workpiece moves to the position directly below the hydraulic three-jaw chuck 1.

[0034] The hydraulic telescopic rod 8 pushes the connecting frame 9 and the hydraulic three-jaw chuck 1 downwards to above the workpiece, and then the chuck moves down to clamp the workpiece. The pressure telescopic rod 14 retracts, causing the turntable 3 to descend a certain height, so that the workpiece is detached from the annular support table 11 and suspended in the air, ensuring processing space.

[0035] The internal hole of the workpiece is threaded using external equipment, while the turntable 3, driven by the stepper motor 13, rotates the workpiece to facilitate the machining. After the current workpiece is machined, the hydraulic telescopic rod 14 lifts the turntable 3 to reset, and the bottom of the workpiece falls back onto the annular support platform 11. The hydraulic three-jaw chuck 1 releases and returns to its original position, and the stepper motor 13 drives the turntable 3 to rotate to the next station.

[0036] When the finished workpiece rotates to the unloading port 4 position with the turntable 3, the workpiece falls into the unloading port 4 through the positioning through hole 2 by its own weight, completing the automatic unloading. During the rotation of the turntable 3, the strip rubber plate 10 on its lower surface contacts the annular support table 11, which scrapes the metal debris generated during processing to the unloading port 4, keeping the working surface clean.

[0037] It is worth noting that the operation of the stepper motor 13, the extension and retraction sequence of the hydraulic telescopic rod 1 and the hydraulic telescopic rod 2 14, and the clamping and releasing actions of the hydraulic three-jaw chuck 1 are all coordinated by the PLC control system.

[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
