Description

TECHNICAL FIELD

[0002] The bolt tapping machine is a special equipment for processing internal thread on the bolt, mainly composed of a machine body, a power system, a clamping and positioning device, a tapping execution mechanism and a cooling and chip removal system, wherein the cooling and chip removal system is used for spraying cooling liquid on the tap during tapping, so as to reduce the cutting temperature and prolong the service life of the tap.

[0003] The iron filings generated during tapping will flow back into the collection tank along with the falling cooling liquid on the flow guide groove. The iron filings carried by the cooling liquid are preliminarily separated by a mesh or filter screen to prevent debris from entering the circulating pump. Some devices are provided with magnets at the bottom of the collection tank to adsorb metal debris, or a multiple filtering system is provided for step-by-step interception to improve the separation efficiency. However, the above separation means has the following problems: the surface of the magnet is saturated after long-term use, which causes the subsequent iron filings to be unable to be effectively adsorbed, and even the adsorbed iron filings fall off due to the decay of the magnetic force. The multiple filtering system is limited by the aperture of the filter screen, so that large particles of iron filings are blocked on the filter screen, affecting the interception and filtering range of the filter screen, and small particles of iron filings can directly pass through the filter screen. After the iron filings are mixed with the cooling liquid again, they not only impact the fan blades of the circulating pump to cause wear, but also block the cooling liquid nozzle, thereby reducing the spraying cooling effect on the tap.

DETAILED DESCRIPTION

[0045] In order to make the above-mentioned objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0046] Example 1, refer to Figures 1-8 For the first embodiment of the present application, a tapping machine for bolt processing is provided, which comprises a tapping machine main body 1, a flow guide groove 2 is connected to the workbench of the tapping machine main body 1, a collection box 3 is arranged at the lower side of the lowest end of the flow guide groove 2, a fixed box 5 is fixedly installed on the top surface of the collection box 3, a slow flow plate 6 is fixedly connected to the upper part of the fixed box 5 in an inclined manner, the bottom of the side of the fixed box 5 located at the lowest end of the slow flow plate 6 is in communication with the collection box 3, a leakage hole 61 is formed in the middle of the slow flow plate 6, an intercepting plate 7 is fixedly connected to the slow flow plate 6 on one side of the leakage hole 61, a sedimentation pipe 8 is fixedly connected to the bottom of the leakage hole 61, and a cleaning mechanism 9 is arranged at the lower side of the sedimentation pipe 8; the cleaning mechanism 9 comprises a transfer piece 91 rotatably connected to the bottom of the slow flow plate 6, the transfer piece 91 is in a cylindrical structure, the circular arc surface of the transfer piece 91 abuts against the lower end of the sedimentation pipe 8, a plurality of transfer grooves 92 are formed in the transfer piece 91 in a ring shape and at equal intervals, a collection bucket 95 is arranged at the lower side of the transfer piece 91, and the collection bucket 95 is placed at the bottom of the fixed box 5; a waterwheel 10 is rotatably connected to the fixed box 5 on one side of the lowest end of the slow flow plate 6, a transmission piece 11 is connected between the waterwheel 10 and the cleaning mechanism 9, the iron filings flow into the sedimentation pipe 8 and accumulate in the transfer groove 92 with the opening arranged upward, the cooling liquid drives the waterwheel 10 to rotate, the waterwheel 10 drives the transfer piece 91 to rotate through the transmission piece 11, and the transfer groove 92 filled with iron filings flows into the collection bucket 95 after the opening of the transfer groove 92 is downward.

[0047] Specifically, the iron filings and the cooling liquid generated by the bolt tapping of the tapping machine body 1 flow to the highest end of the slow flow plate 6 through the flow guide groove 2. The cooling liquid slowly flows along the inclined surface of the slow flow plate 6. The iron filings are intercepted by the intercepting plate 7 and accumulated on the slow flow plate 6. The flow of the cooling liquid drives the iron filings to move into the sedimentation pipe 8 through the leakage hole 61. The flow rate of the liquid in the sedimentation pipe 8 is reduced, so that the iron filings are deposited in the transfer groove 92 with the opening upward. After the cooling liquid leaves the slow flow plate 6, it flows into the water tank of the waterwheel 10. The waterwheel 10 rotates and drives the transfer member 91 to rotate intermittently through the transmission member 11, so that all the transfer grooves 92 are in turn abutted with the lower end port of the sedimentation pipe 8. When the transfer groove 92 with the iron filings has the opening downward, it drives the iron filings to flow into the collection barrel 95, realizing the separation of the iron filings and the cooling liquid.

[0048] Wherein, after the iron filings flow into the sedimentation pipe 8, the internal environment of the sedimentation pipe 8 is less affected by the flow of the liquid, so that the iron filings inside the sedimentation pipe 8 can gradually deposit downward. The opening of the transfer groove 92 with the opening upward is communicated with the lower end port of the sedimentation pipe 8, so that the iron filings are finally accumulated in the transfer groove 92.

[0049] With reference to Figures 2-3 The flow guide pipe 4 is fixedly connected to the bottom of the flow guide groove 2, and the lower end port of the flow guide pipe 4 is arranged above the highest end of the slow flow plate 6.

[0050] Specifically, a plurality of through holes are arranged in the bottom of the flow guide groove 2. The gap of the through holes is smaller than the size of the bolt. The processed bolt falls on the flow guide groove 2 and moves to the lower end through the inclined surface of the flow guide groove 2. The cooling liquid and the iron filings flow into the flow guide pipe 4 through the through holes and flow to the top surface of the highest end of the slow flow plate 6 through the flow guide pipe 4.

[0052] Specifically, the intercepting plate 7 intercepts the moving iron filings. After the cooling liquid flows over the intercepting plate 7, it continues to flow to the lower end of the slow flow plate 6. At the same time, the cooling liquid at the bottom layer moves to the middle part under the guidance of the intercepting plate 7, driving the accumulated iron filings to move to the leakage hole 61. The arrangement of the arc-shaped concave surface 71 avoids the generation of dead angles between the intercepting plate 7 and the slow flow plate 6, and at the same time, it can improve the smoothness of the movement of the cooling liquid along the direction of the intercepting plate 7, improve the movement efficiency of the iron filings driven by the cooling liquid to the leakage hole 61, and avoid the accumulation of the iron filings.

[0053] It can be understood that the gravity of the iron filings is greater than the gravity of the cooling liquid, so that the iron filings gradually move downward to the top surface of the slow flow plate 6 when the cooling liquid carrying the iron filings moves on the slow flow plate 6, and gradually move under the scouring of the cooling liquid, and the movement of the iron filings is intercepted under the arrangement of the intercepting plate 7, and after the cooling liquid surface is higher than the top surface of the intercepting plate 7, the cooling liquid can overflow the intercepting plate 7 and continue to flow downward.

[0059] The T-shaped block 93 is composed of a rubber plug in a cavity structure and a solid metal counterweight block, the rubber plug is attached to the inner wall of the conveying groove 92, and when the conveying groove 92 is opened downward and in a non-vertical state, the counterweight block pushes the rubber plug to slide along the inner wall of the conveying groove 92 to completely push out the iron filings in the conveying groove 92.

[0062] Wherein, the sector gear 112 drives the transmission gear 111 to rotate by a certain angle when the sector gear 112 rotates one circle, so that the current rotating tank 92 moves to the position of the next rotating tank 92 in the rotating direction, and the rotating member 91 is connected with the rotating seat through a bearing, and the rotating member 91 is made of plastic material, so that the gravity of the rotating member 91 can be reduced, and the waterwheel 10 can effectively drive the rotating member 91 to rotate.

[0072] With reference to Figures 10-11The fixed plate 131 is arranged at the right side of the leakage hole 61, and two inclined surfaces are symmetrically arranged at the right part, the leakage hole 61 can be shielded by the fixed plate 131, so that the cooling liquid cannot directly flow into the sedimentation pipe 8, and the influence of the water flow on the internal environment of the sedimentation pipe 8 is further reduced.

[0073] With reference to Figure 12 The slow-flow plate 6 and the flow distribution plate 132 are inclined to the same side, the angle between the flow inclined surface of the slow-flow plate 6 and the horizontal line is a, the angle between the top surface of the flow distribution inclined surface 133 and the horizontal line is b, the a angle is greater than the b angle, and the remaining structure is the same as that of the embodiment 2.

[0074] In combination with the embodiments 1-3, the working principle of the present application is as follows: after the bolt is threaded by the tapping machine main body 1, the bolt slides downward through the flow guide groove 2, the iron filings and the cooling liquid flow into the flow guide pipe 4 through the through hole of the flow guide groove 2, and flow to the uppermost end of the slow-flow plate 6, the cooling liquid slowly flows along the inclined surface of the slow-flow plate 6, the iron filings are blocked by the intercepting plate 7 and accumulated on the slow-flow plate 6, the flow of the cooling liquid drives the iron filings to move into the sedimentation pipe 8 through the leakage hole 61, the iron filings are deposited in the transfer groove 92 with the opening upward, the cooling liquid flows into the water tank of the waterwheel 10 after leaving the slow-flow plate 6, the waterwheel 10 rotates and drives the transfer member 91 to intermittently rotate through the transmission member 11, when the transfer groove 92 with the iron filings is opened downward, the iron filings flow into the collecting hopper 125 through the flow guide cover 94, and finally are accumulated in the collecting barrel 95 after sliding through the buoyancy bin 123, the cooling liquid in the collecting barrel 95 enters through the through hole at the bottom surface of the buoyancy bin 123, and is discharged into the collecting box 3 through the telescopic pipe 124.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
