Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a tap guide for improving tapping quality. Background Art
[0002] In the process of mechanical processing of materials, we often encounter some methods of tapping threads on surface planes, among which manual tapping is a commonly used method. When tapping by hand, directly tapping with a tap can easily lead to the thread profile being not perpendicular to the surface plane, failing to meet the design requirements and achieving the ideal effect. The quality of the thread sometimes varies due to different technical levels of each person, and the stability of the thread quality cannot be guaranteed, and the ideal effect cannot be achieved. The quality is mainly reflected in the uneven thread profile and the coaxiality of the thread profile and the thread bottom hole failing to meet the required technical indicators, resulting in the failure of the thread inspection gauge to pass, affecting the delivery status of the final product. Utility Model Content
[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a tap guide for improving tapping quality, which solves the problem in the prior art that manual direct tapping easily causes irregular thread profiles and affects tapping quality.
[0004] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is:
[0005] A tap guide for improving tapping quality is provided, which comprises a guide seat, on which a plurality of guide holes are arranged, and the diameters of the plurality of guide holes are all different.
[0006] The principle of the tap guide in the present application is as follows: when tapping the tapped hole, first take the tap of the specification to be tapped, place the tap on the tapping rack and tighten it, then apply a little tapping lubricant on the tap surface with a brush, place the guide seat on the surface of the tapped hole, and then put the working part of the tap into the guide hole corresponding to the guide seat. Grasp the guide seat with your left hand, hold the tapping rack with your right hand, move the lower end face of the guide seat, and make sure that the front end of the tap enters the opening of the tapped hole. At this time, hold the tapping rack with your right hand and rotate it slowly until the tap is determined to have entered the tapped hole for more than 3 to 4 turns, then release and remove the tapping rack, and take the guide seat out along the tap. Finally, apply a little tapping lubricant on the working end of the tap again, and then tighten the tapping rack again. Place both hands horizontally, hold the left and right sides of the tapping rack, and evenly rotate to tap out the remaining threaded parts. Use compressed air to blow away the chips produced by tapping, and rotate the tap in the opposite direction to complete the processing of the entire threaded hole.
[0007] Furthermore, the guide seat is of a cylindrical structure, and a plurality of guide holes with different diameters are vertically penetrated through the upper end surface of the guide seat, and the plurality of guide holes are arranged at intervals in an annular direction with the axis of the guide seat as the center.
[0008] The arrangement of multiple guide holes with different diameters enables the entire tap guide to match taps of different models and specifications, thereby improving the use range and flexibility of the entire tap guide.
[0009] Furthermore, a hand-holding portion is provided on the circumferential outer wall at the top of the guide seat. The hand-holding portion is provided to facilitate the operator to hold and fix the guide seat during the tapping process, thereby avoiding the guide seat from being skewed and improving the quality of thread profile forming.
[0010] Furthermore, as a specific arrangement of the hand-held portion, the hand-held portion has an arc surface structure that is recessed toward the axis of the guide seat, and the arc radius of the hand-held portion is 10 mm.
[0011] Furthermore, a blind hole is provided on the lower end face of the guide seat, the axis of the blind hole coincides with the axis of the guide seat, and the bottoms of multiple guide holes are connected to the blind hole; the provision of the blind hole not only facilitates the tap to pass through the guide hole and align with the opening of the tapped hole, but also facilitates the tap to discharge chips.
[0012] Furthermore, the circumferential outer edges of the upper and lower end surfaces of the guide seat are both provided with rounded corners, which can eliminate the sharp edges of the upper and lower end surfaces of the guide seat and reduce the risk of injury to operators during the use of the tap guide.
[0013] Furthermore, the height of the guide seat is 75mm to 10mm, and the diameter of the guide seat is 50mm to 70mm; through the above technical scheme, the overall size of the guide seat is limited so that the guide seat matches the gripping range of the operator's hand, thereby improving the operator's hand's grasp of the guide seat during thread tapping.
[0014] The beneficial effects of the utility model are as follows: the tap guide provided by the present invention improves the tapping quality, adopts a quick and easy manual pushing guide seat and an operation mode combining the tap with the guide hole, which effectively improves the thread profile forming quality, enhances the product quality competitiveness of parts containing threaded holes, and solves the problem in the prior art that the thread profile is easily misaligned during manual direct tapping, thus affecting the tapping quality.
