Description

Technical Field

[0002] In the tap processing process, groove grinding, thread grinding and cutting cone grinding are key steps. Groove grinding of taps mainly refers to grinding the cutting groove of the tap to form a suitable chip space.

Cutting cone grinding refers to grinding the cutting part of the tap to form a sharp cutting edge.

[0003] The tap process positioning assembly is a device used in the tap production process. Its function is to accurately position and fix the tap in different processing steps to ensure processing accuracy and efficiency.

[0031] As a further implementation of this solution, the tap body 1 is installed inside the placement groove 36, with the bottom end of the tap body 1 abutting against the top end of the turntable 37, and the outer side of the lower end of the tap body 1 abutting against one side of the multiple contact heads 53. The flat surface of the square head of the tap body 1 is roughly aligned with the multiple contact heads 53, which facilitates the subsequent fixing of the tap body 1.

[0032] As a further implementation of this solution, the opening shape of the limiting slide 32 is a three-section rectangular body, the number of the limiting slides 32 is four, the limiting slide 32 passes through the upper end of the base 31, and the lower slide 41 is slidably connected to the inner side of the limiting slide 32 through the rail 42. The turntable 37 is in the shape of a cylinder. The turntable 37 is between the upper frame plate 35 and the base 31, and a spacing is provided between the upper frame plate 35 and the base 31. The opening shape of the arc path 38 is an arc body, and the arc path 38 passes through the inner side of the turntable 37. The outer side of the passive column 43 is fitted with the inner side of the arc path 38 opened by the turntable 37, and the shape of the passive column 43 is a cylinder. , both sides of the lower slide plate 41 are fixedly connected to the rails 42, and the number of the lower slide plates 41 is four.

[0033] As a further implementation of this scheme, a sliding hole is opened on the inner side of the vertical plate 51 near the resistor column 55, and the number of guide slide rods 52 is four groups, with two guide slide rods 52 in each group. The column hole 57 passes through the inner side of the vertical plate 51, and the opening shape of the column hole 57 is cylindrical. The resistor column 55 slides on the inner side of the column hole 57, and the bottom end of the resistor column 55 is electrically connected to the top of the electrical connector 58. A mounting groove is opened on the inner side of the vertical plate 51 near the second soft wire 59. The second soft wire 59 is connected to the negative terminal of the controller 2, and the first soft wire 56 is connected to the positive terminal of the controller 2. The first soft wire 56 is electrically connected to the resistor column 55. A rubber band 6 is fixed between the vertical plate 51 and the contact head 53. The change in resistance value is used to determine whether the tap is tilted, thereby achieving further precise adjustment of the tap position. This not only improves the processing accuracy, but also reduces the error and labor intensity of manual operation, thereby ensuring the quality of the processed product.

[0034] The work process is as follows: when the tap body 1 is quickly positioned and the alignment of the square head at the bottom end of the tap body 1 with the cutting groove is understood in real time, the tap body 1 is placed inside the placement groove 36, and the bottom end of the tap body 1 is fitted with the top end in the middle of the turntable 37. The servo motor 33 is started to drive the turntable 37 to rotate. The turntable 37 rotates through the arc path 38 to push the four passive columns 43 to move toward the square head of the tap body 1 at the same time. The passive columns 43 drive the lower slide 41 and the positioning block 44 to move at the same time. The lower slide 41 is slidably connected to the inner side of the limiting slide 32 through the rail 42, and the positioning block 44 is slidably connected to the inner side of the lower end of the upper frame plate 35 through the rectangular bar 45, which improves the stability of the positioning block 44 when moving. The four positioning blocks 44 squeeze the square head at the lower end of the tap body 1 at the same time, thereby realizing the function of quickly positioning the tap body 1. After the positioning is completed, the main shaft of the servo motor 33 is self-locking, thereby ensuring the stability of the tap body 1. At the same time, when the lower slide 41 moves, The movable riser 51 and the device on its upper end move simultaneously. When the four contact heads 53 contact the outer side of the tap body 1, the contact heads 53 drive the guide slide 52 and the conductive block 54 to move simultaneously. When the contact heads 53 move, the rubber band 6 deforms, which serves to reset the contact heads 53. The conductive block 54 slides on the outer side of the resistor column 55 through the column hole 57. The riser 51 drives the electrical connector 58 to move. The second flexible wire 59 and the first flexible wire 56 are flexible wires and do not affect the normal movement of the riser 51. At this time, the contact position between the electrical connector 58 and the resistor column 55 changes. Under the condition that the rated voltage and rated current remain unchanged, the resistance value of this circuit is detected by the controller 2 to determine the resistance value of this circuit. When the four resistance values ​​are compared, if there is a difference between their values, it indicates that the tap body 1 is tilted. The square head at the bottom of the tap body 1 is not aligned with the cutting groove at the top. Repositioning is required to ensure the accuracy of the tap body 1 during processing.
