Description

Technical Field

[0001] This utility model relates to the field of fully automatic tapping machine technology, and in particular to a screw tapping machine. Background Technology

[0002] A screw tapping machine (also known as a thread tapping machine) is a special equipment used to process threads (internal threads) in holes. It processes the inner wall of the screw hole into a thread structure that matches the bolt by means of rotary cutting or extrusion forming.

[0003] When using existing screw tapping machines, the inner wall of the screw hole is processed by rotating the tapping head. However, the waste generated during the processing easily falls into the screw hole. Since the inner diameter of the screw hole is small, it is not convenient to clean the waste inside the screw hole, which affects the use of the screw hole. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the inability to clean the debris inside screw holes in the prior art, and to propose a screw tapping machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screw tapping machine includes a mounting plate with two symmetrically arranged fixing plates. Between the two fixing plates are two clamping plates for fixing the sheet metal to be tapped on the mounting plate. A mounting cylinder is located directly above the clamping plates. A horizontal plate is fixedly installed on the outer wall of the mounting cylinder, and a hydraulic cylinder is mounted on the horizontal plate. An air pump is fixedly installed at the bottom of the hydraulic cylinder, and a nozzle is provided at the bottom of the air pump to blow high-pressure air into the screw hole and blow out the screw hole debris.

[0007] Preferably, a slide rail is fixedly mounted on the mounting plate, a sliding plate is slidably mounted on the slide rail, and an electric telescopic rod for driving the mounting cylinder to move laterally is fixedly mounted on the sliding plate.

[0008] Preferably, a servo motor is fixedly mounted on the outer wall of the mounting cylinder, a drive gear is fixedly mounted on the output end of the servo motor, and a gear ring is provided on the outer wall of the drive gear to mesh with the drive gear.

[0009] Preferably, the drive gear is eccentrically positioned inside the gear ring, an arc-shaped plate is fixedly installed on the outer wall of the gear ring, and three fixing rods are fixedly installed on the outer wall of the mounting cylinder relative to the servo motor, with a limit frame fixedly installed at the ends of the three fixing rods.

[0010] Preferably, the arc-shaped plate is slidably disposed within the limiting frame, a limiting frame with a U-shaped structure disposed below the servo motor is fixedly installed on the mounting cylinder, and a movable plate is fixedly installed on the outer wall of the gear ring, with the outer wall of the movable plate in contact with the limiting frame.

[0011] Preferably, a hydraulic rod is fixedly installed at the bottom end of the movable plate, a drive motor is fixedly installed at the bottom end of the hydraulic rod, and a tapping head for machining screw holes is fixedly installed at the output end of the drive motor.

[0012] Preferably, two symmetrically arranged electric push rods are fixedly installed between the two fixed plates, and the ends of the two electric push rods are fixedly connected to a clamping plate.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model uses the sliding of the sliding plate and the extension and retraction of the electric telescopic rod to position the nozzle directly above the screw hole. Driven by the hydraulic cylinder, the nozzle cleans the debris inside the screw hole, preventing debris from accumulating inside the screw hole and affecting its use.

[0015] 2. This utility model uses the rotation of the drive gear to make the moving plate rotate with the rotation of the gear ring, changing the included angle between the tapping head and the mounting plate, so that the bottom end of the tapping head is away from the screw hole, thus preventing waste from adhering to the screw head during the hole cleaning process and affecting the use of the screw head.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A screw tapping machine includes a mounting plate 1, on which two symmetrically arranged fixing plates 2 are provided, and between the two fixing plates 2 are two clamping plates 4 for fixing the material to be tapped on the mounting plate 1. A mounting cylinder 8 is provided directly above the clamping plates 4, and a horizontal plate 20 is fixedly installed on the outer wall of the mounting cylinder 8. A hydraulic cylinder 21 is provided on the horizontal plate 20, and an air pump 22 is fixedly installed at the bottom end of the hydraulic cylinder 21. A nozzle 23 is provided at the bottom end of the air pump 22 to blow high-pressure airflow into the screw hole and blow out the screw hole debris.

[0023] A slide rail 5 is fixedly installed on the mounting plate 1, a sliding plate 6 is slidably mounted on the slide rail 5, and an electric telescopic rod 7 that drives the mounting cylinder 8 to move laterally is fixedly installed on the sliding plate 6.

[0024] A servo motor 9 is fixedly installed on the outer wall of the mounting cylinder 8. A drive gear 10 is fixedly installed on the output end of the servo motor 9. A gear ring 14 that meshes with the drive gear 10 is provided on the outer wall of the drive gear 10.

[0025] The drive gear 10 is eccentrically positioned inside the gear ring 14. An arc-shaped plate 13 is fixedly installed on the outer wall of the gear ring 14. Three fixing rods 11 are fixedly installed on the outer wall of the mounting cylinder 8 directly above the servo motor 9, and the ends of the three fixing rods 11 are jointly fixedly installed with a limit frame 12.

[0026] The arc-shaped plate 13 is slidably disposed within the limiting frame 12. A limiting frame 16 with a U-shaped structure is fixedly installed on the mounting cylinder 8 and located below the servo motor 9. A movable plate 15 is fixedly installed on the outer wall of the gear ring 14, and the outer wall of the movable plate 15 is in contact with the limiting frame 16.

[0027] A hydraulic rod 17 is fixedly installed at the bottom of the movable plate 15, a drive motor 18 is fixedly installed at the bottom of the hydraulic rod 17, and a tapping head 19 for machining screw holes is fixedly installed at the output end of the drive motor 18.

[0028] Two symmetrically arranged electric push rods 3 are fixedly installed between the two fixed plates 2, and the ends of the two electric push rods 3 are fixedly connected to a clamping plate 4.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] In use, the plate to be tapped is placed on the mounting plate 1, and the electric push rod 3 is extended and retracted to move the clamping plate 4, so that the clamping plate 4 moves toward the plate and fixes the plate, thus preventing the plate from sliding during the tapping process and affecting the tapping quality.

[0031] The sliding plate 6 slides on the slide rail 5, and the electric telescopic rod 7 extends and retracts to adjust the position of the tapping head 19 so that the tapping head 19 is placed directly above the screw hole. The extension and retraction of the hydraulic rod 17 causes the tapping head 19 to move down, and the drive motor 18 drives the tapping head 19 to rotate and tap the screw hole.

[0032] When tapping is complete, the servo motor 9 is turned on, causing the output of the servo motor 9 to drive the drive gear 10 to rotate. The drive gear 10 then drives the meshing gear ring 14 to rotate. The arc plate 13 is slidably set within the limit frame 12, causing the gear ring 14 to drive the moving plate 15 to rotate 90 degrees, preventing debris from adhering to the tapping head 19. The extension and retraction of the electric telescopic rod 7 places the nozzle 23 directly above the screw hole. The hydraulic cylinder 21 drives the air pump 22 to move downward, allowing the nozzle 23 to clean the debris from the screw hole.
