Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically a vertical tapping mechanism for a vertical and horizontal double-sided drilling and tapping machine. Background Technology

[0002] A tapping machine is a machine tool used to process threads. It forms threads by rotating the tapping tool and applying sufficient high-speed rotation to the surface of the workpiece. A drilling machine is a machine tool used to drill holes in metal, wood or other materials. Currently, vertical and horizontal double-sided drilling and tapping machines on the market provide tapping and drilling materials. Users can choose the appropriate mechanism to process parts according to their actual needs.

[0003] However, traditional machining has the following drawbacks:

[0004] (1) Traditional tapping mechanisms require two operations to perform tapping: first stamping and then tapping, resulting in low production efficiency;

[0005] (2) When tapping deep holes, the contact time between the tool and the workpiece may be long due to the secondary operation, which may easily generate cutting heat and excessive cutting force, resulting in an increased equipment failure rate. Utility Model Content

[0006] The purpose of this utility model is to provide a vertical tapping mechanism for a vertical and horizontal double-sided drilling and tapping machine, so as to solve the problems mentioned in the background art. Traditional tapping mechanisms require two operations for tapping, namely, stamping and tapping, which results in low production efficiency. When tapping deep holes, the contact time between the tool and the workpiece may be long due to the secondary operation, which can easily generate cutting heat and excessive cutting force, leading to an increased equipment failure rate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vertical tapping mechanism for a vertical and horizontal double-sided drilling and tapping machine, comprising a vertical raised base, a cast column fixedly installed at the top of the vertical raised base, a limit plate fixedly installed at the bottom of one side of the cast column, a screw support plate fixedly installed on one side of the limit plate on the cast column, a screw fixing plate fixedly installed at the top of one side of the cast column, a ball screw rotatably connected between the screw support plate and the screw fixing plate, linear slide rails fixedly installed at both ends of one side of the cast column, two symmetrically arranged sliding blocks slidably connected at the middle of the two linear slide rails, a multi-spindle fixing plate fixedly installed between the four sliding blocks, a multi-spindle connecting plate fixedly installed at the middle of one side of the multi-spindle fixing plate, a multi-spindle body provided on one side of the multi-spindle connecting plate, and a screw nut fixedly installed at the middle of the bottom end of the multi-spindle fixing plate.

[0008] Preferably, a multi-spindle cover plate is fixedly installed at the top of the multi-spindle body, the top of the multi-spindle cover plate is fixedly connected to the bottom of the multi-spindle connecting plate, a spindle servo motor mounting base is fixedly installed at the top of the multi-spindle connecting plate, a spindle servo motor is fixedly installed at the top of the spindle servo motor mounting base, two lead screw support plates extending to the outside are fixedly installed on both sides of the bottom of the multi-spindle connecting plate, a tapping swing arm fixing plate is fixedly installed at the bottom between the two lead screw support plates, and two symmetrically arranged tapping swing arms are fixedly installed on both sides of the bottom of the tapping swing arm fixing plate.

[0009] Preferably, symmetrically arranged universal joints are fixedly installed on both sides of the bottom end of the multi-axis device body. The bottom ends of the two universal joints are respectively fixedly connected to the top ends of the two tapping arms. The output end of the spindle servo motor is fixedly connected to the side of the multi-axis device body facing the main body. Baffles are fixedly installed on both sides of the top end of the multi-axis device connecting plate. After the spindle servo motor is powered on, it starts and drives the multi-axis device body to move. The multi-axis device body drives the tapping arms to move synchronously through the universal joints, and the tapping arms perform tapping.

[0010] Preferably, limit sensor platforms are fixedly installed on both sides of the casting column, and limit sensor switches are fixedly installed on one side of each of the four limit sensor platforms. The limit sensor switches detect the position of the multi-axis fixing plate in real time, and control the state of the switch by the sensing signal generated when an object approaches the switch.

[0011] Preferably, a feed servo motor mounting base is fixedly installed at the top of the casting column, and a feed servo motor is fixedly installed at the top of the feed servo motor mounting base. A coupling is fixedly installed through the feed servo motor mounting base at the output end of the feed servo motor. One end of the coupling is fixedly connected to the end of the ball screw directly opposite it. After the feed servo motor is powered on, it starts and drives the ball screw to rotate through the coupling. The thread on the surface of the ball screw matches the thread on the inner wall of the screw nut, and the screw nut is limited by the multi-axis fixing plate. The sliding block on the multi-axis fixing plate slides along the linear slide rail, thereby adjusting the position of the multi-axis fixing plate.

[0012] Preferably, the lead screw nut is threadedly connected to the ball screw, and the threads on the inner wall of the lead screw nut match the threads on the surface of the ball screw, so the lead screw nut slides relative to the ball screw.

[0013] Preferably, the four corners of the top of the vertical raised base are provided with first threaded holes, and the four corners of the bottom of the cast column are provided with second threaded holes. When the user screws the screw through the first threaded hole, the thread on the surface of the screw matches the thread on the inner wall of the first threaded hole, thus fixing the vertical raised base to the tapping machine. When the user screws the screw through the second threaded hole, the thread on the surface of the screw matches the thread on the inner wall of the second threaded hole, so the screw rotates and rises relative to the second threaded hole, assembling the cast column and the vertical raised base together.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a multi-spindle connecting plate, linear slide rail and sliding block, the lead screw nut slides relative to the ball screw, and the lead screw nut drives the sliding block on the multi-spindle connecting plate to slide along the linear slide rail, thereby adjusting the height of the tapping arm. The tapping arm directly performs tapping operation on the workpiece, replacing the traditional secondary operation, and directly completes tapping to a fixed depth. The operation is simple and convenient.

[0016] 2. By setting up a tapping arm, universal joint and multi-axis main body, the main spindle servo motor drives the tapping arm to rotate, thus realizing tapping. This avoids the phenomenon of prolonged contact time between the part and the tapping arm due to secondary operation, and extends the service life of the equipment. Attached Figure Description
