Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a replaceable screwdriver head for hot melt drilling equipment. Background Art

[0002] During the machining process, under the action of high-speed rotation force and downward pressure, the high-speed rotating hot melt drill rubs violently with the metal part to be processed, generating a temperature of up to 600 to 700 degrees. The contact part becomes red and soft due to the high temperature, and then is stretched downward to form a round hole. The height of the processed hole is two to three times the thickness of the original thin metal plate or tube cross section. Therefore, hot melt drilling technology can replace drilling, welding nuts and riveting nuts without spot welding cylinder gaskets or nuts.

[0003] When replacing the replaceable screwdriver head of the existing hot melt drilling equipment, personnel need to manually turn the bolt to thread the screwdriver head, the main body and the nut to achieve disassembly and assembly, which makes it time-consuming and laborious for personnel to turn the bolt during disassembly and assembly. At the same time, when the cutter head is hot-melt drilling, the hot melt equipment drives the cutter head to drill, and the drilling spindle and the drill bit have radial deflection or looseness, which makes the cutter head easy to deviate, resulting in poor accuracy of hot-melt drilling and reduced practicality of the equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a replaceable screwdriver head for hot melt drilling equipment, which has the advantages of easy replacement of the screwdriver head and stable operation of the cutter body, and solves the problems raised by the above background technology.

[0005] The utility model provides the following technical solution: a replaceable screwdriver head for hot melt drilling equipment, comprising a body, a controller fixedly installed on the outer wall of the body, a workbench installed on the outer wall of the body, a main body fixedly installed on the top of the body, a pillar fixedly installed on the bottom of the main body, a support plate fixedly installed on the outer wall of the pillar, a first motor fixedly installed on the outer wall of the support plate, a power output shaft of the first motor fixedly equipped with a cooling fan, a motor fixedly installed on the bottom of the support plate, a screw rod fixedly installed on the power output shaft of the motor, a fixing block threadedly connected to the outer wall of the screw rod, a spring fixedly installed on the inner wall of the pillar, a circular plate fixedly provided on one end of the spring, a cutter body installed on the bottom of the circular plate, a clamping block fixedly provided on the outer wall of the cutter body, a clamping groove installed on the outer wall of the clamping block, and a sliding groove provided on the inner wall of the pillar.

[0006] As a preferred technical solution of the present invention: an electrical connection is formed between the controller and the first motor, the number of the cooling fans is two, and the two cooling fans are symmetrically arranged with the blade body as the center.

[0007] As an optimal technical solution of the present invention: an electrical connection is formed between the controller and the motor, the screw rod is composed of a positive thread rod and a negative thread rod, and the outer walls of the positive thread rod and the negative thread rod are respectively threadedly connected to the inner wall of the fixed block.

[0008] As a preferred technical solution of the present invention: a round rod is fixedly installed on the bottom of the support plate, and the outer wall of the round rod is slidably connected to the outer wall of the fixed block.

[0009] As a preferred technical solution of the present invention: a circular groove is provided on the inner wall of the pillar, and the inner wall of the circular groove is in sliding connection with the outer wall of the cutter body.

[0010] As a preferred technical solution of the present invention: one end of the spring is fixed to the top of the circular plate, and the other end of the spring is fixed to the top inner wall of the support.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The replaceable screwdriver head of the hot melt drilling equipment uses the cutter body to drive the card block through the circular groove into the inner wall of the pillar. The card block slides on the inner wall of the slide groove and abuts against the bottom of the circular plate. The cutter body drives the card block to push the circular plate to compress the spring. The rotating cutter body drives the card block to rotate to the card slot. The spring elastic force is released to push the circular plate to form a card connection between the card block and the card slot, so that the connection between the cutter body and the pillar is stable, which is convenient for personnel to disassemble and replace the cutter body.

[0013] 2. The replaceable screwdriver head of the hot melt drilling equipment is driven by the motor to rotate through the control controller. The positive threaded rod and the reverse threaded rod respectively drive the fixed blocks to approach each other. The two fixed blocks are used to slide on the outer wall of the round rod so that the two fixed blocks are limited on the outer wall of the round rod to avoid displacement of the moving position. The two fixed blocks are used to clamp and fix the cutter body to achieve precise positioning of the cutter body during hot melt drilling. BRIEF DESCRIPTION OF THE DRAWINGS
