Description

Technical Field

[0001] The utility model relates to the technical field of electric tapping machines, in particular to an anti-error structure of a cantilever electric tapping machine. Background Art

[0002] An electric tapping machine is an electric tool used to process internal threads. It is a machine tool that can tap internal threads of various small and large steel parts with coarse pitch, fine pitch, forward and reverse fastening connection threads, transmission connection threads and pipe threads. This type of machine tool belongs to the category of flexible tapping.

[0003] Since the existing electric tapping machines have basically achieved CNC settings, when the operator sets the data, the tapping machine runs automatically and the drill bit drills into the interior of the workpiece. The operator cannot observe the actual tapping depth of the tapping machine by naked eye, which can easily cause the operator to tap too deep when entering incorrect data.

[0004] In view of this, we propose an error-proof structure for a cantilever electric tapping machine. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 - Figure 4 , the utility model provides a technical solution:

[0024] A cantilever electric tapping machine error prevention structure, comprising a fixing fixture 1, a mechanical warning rod 2, wherein the fixing fixture 1 is provided with the mechanical warning rod 2 on one side, wherein the mechanical warning rod 2 comprises a contact plate 21 and an extension rod 22, wherein the contact plate 21 is provided at the bottom end of the extension rod 22, wherein the extension rod 22 is provided inside a sleeve 27, wherein the end of the sleeve 27 is connected with a traction rope 28, wherein the end of the traction rope 28 is connected with a fixing bracket 24, wherein the sleeve 27 penetrates the fixing bracket 24, and wherein the side of the sleeve 27 is connected with a signal lamp 25 A warning strip 26 is provided on the surface of the signal light 25, and a light-transmitting groove is provided on the surface of the warning strip 26. The sleeve rod is slidably connected to the inside of the fixed bracket 24, so that during the tapping process of the drill bit 3, the drill bit 3 clamp drives the fixed bracket 24 to be pressed down, and the extension rod 22 and the sleeve 27 on the surface of the contact plate 21 slide inside the fixed bracket 24, so that the signal light 25 on one side of the sleeve 27 rises synchronously, and the signal light 25 penetrates the light through the signal strip, and the tapping depth of the drill bit 3 is judged by moving the light, reminding the operator to pay attention to the tapping depth.

[0025] The extension rod 22 is slidably connected to the sleeve 27, and the surface of the sleeve 27 passes through the limit bolt 23. The limit bolt 23 passes through the sleeve 27 to fix the internal extension rod 22, so that the contact plate 21 at the end of the extension rod 22 is height-adjustable, so that when the fixing fixture 1 fixes drill bits 3 of different lengths, the contact plate 21 can still be at the same height as the drill bit 3, so that the fixing fixture 1 can be effectively adapted to fix any drill bit 3, and the mechanical warning can be effectively adapted.

[0026] There are two traction ropes 28 , which are respectively arranged at two ends of the sleeve 27 . The two traction ropes 28 ensure that both sides of the sleeve 27 are evenly stressed and the sleeve 27 is vertically raised inside the fixed bracket 24 .

[0027] There are multiple light-transmitting grooves, which are equidistantly distributed on the surface of the warning strip 26. The warning strip 26 is made of opaque material. When the signal light 25 is at the bottom of the warning strip 26, it can only emit light through the light-transmitting grooves, so that when the signal light 25 moves, the light can flash when it scatters light through the warning strip 26 to warn the operator.

[0028] The light-transmitting groove is made of translucent plastic material, and the color of the light-transmitting groove is different. The color of the light-transmitting groove ranges from green to yellow to red, and the color gradually becomes darker. Through the light-transmitting grooves of different colors, the color change further reminds the operator to pay attention to the tapping depth of the tapping machine.

[0029] The traction rope 28 is made of an elastic rubber tube. Through the elastic traction rope 28 and the traction ropes 28 on both sides, after the drill bit 3 completes tapping, the sleeve 27 is automatically reset through the traction ropes 28 made of elastic rubber tubes at both ends, so that the error-proofing device can continue to work.

[0030] When the error-proof structure of the cantilever electric tapping machine of the utility model is used, the fixing fixture 1 needs to be installed on the tapping machine before use, and then the drill bit 3 needs to be installed. After the drill bit 3 is installed, the height of the contact plate 21 needs to be adjusted so that the contact plate 21 is flush with the drill bit 3, and the limit bolt 23 is loosened to adjust the extension rod 22. The extension length is adjusted so that the contact plate 21 at the bottom of the extension rod 22 is flush with the drill bit 3, and then the limit bolt 23 is tightened. The extension rod 22 is directly fixed to the sleeve 27 through the limit bolt 23, and then tapping can be started. After the drill bit 3 on the fixing fixture 1 starts tapping, the drill bit 3 fixture drives the fixing bracket 24 to press down, and the contact plate 2 The extension rod 22 and the sleeve 27 on the surface of the 1 slide inside the fixed bracket 24, so that the signal light 25 on one side of the sleeve 27 slides synchronously, and the light of the signal light 25 is emitted through the light-transmitting grooves of the warning strip 26. Since the light-transmitting grooves are equidistantly distributed on the warning strip 26, the signal light 25 produces a flashing light effect during the movement, warning the operator to pay attention to the tapping depth. At the same time, the color of the light-transmitting groove changes from green to yellow to red, so that the color of the warning light changes continuously, further reminding the operator of the tapping depth, preventing the tapping from being too deep, solving the problem that the tapping machine is set incorrectly and the operator cannot observe the tapping depth with the naked eye, improving the controllability of the tapping machine, and reducing tapping operation errors of the tapping machine.
