When the second lead screw 180 rotates, it drives the gear seat 350 to move forward and backward. The forward and backward movement of the gear seat 350 drives the gear 370 and the rack 360 to move forward and backward. When the rack 360 moves forward and backward, the rack 360 slides along the swing rod 330. When the axis of the swing rod 330 is parallel to the axis of the first spline shaft 190, when the rack 360 moves forward and backward, the relative position of the rack 360 and the gear 370 will not change, the rack 360 will not move in the left and right direction, and the gear 370 will not rotate. When the axis of the swing rod 330 has a certain angle with respect to the axis of the No. 1 spline shaft 190, the gear seat 350 drives the gear 370 and the rack 360 to move forward and backward by a certain distance, and the rack 360 is driven to move to the left by the swing rod 330, and the rack 360 drives the gear 370 to rotate, and the rotation of the gear 370 drives the No. 1 spline shaft 190 to rotate, and the rotation of the No. 1 spline shaft 190 drives the No. 1 lead screw 140 to rotate through the belt and the pulley, and the No. 1 lead screw 140 drives 120 and The tool 150 moves axially along the metal easel component, and the tool 150 will be threaded on the metal easel component. Since the pitch of the second lead screw 180 is fixed, the distance that the second lead screw 180 drives the gear seat 350 to move is fixed every time it rotates one circle, and the angle between the axis of the swing rod 330 and the axis of the first spline shaft 190 is fixed. When the gear seat 350 moves a fixed distance, the rack 360 moves left and right by a fixed distance driven by the swing rod 330, and the speed of the gear 370 is fixed, so At this time, the thread line is a fixed pitch, and the fixed pitch can be changed by changing the angle between the rocker arm 330 and the first spline shaft 190.

[0035] When the gear seat 350 moves forward and backward, and at the same time gradually increases the angle between the axis of the rocker arm 330 and the axis of the No. 1 spline shaft 190, the distance that the rack 360 moves left and right will gradually increase at a fixed distance, and the distance that the rack 360 moves left and right will produce an integral effect. At this time, the rotation speed of the gear 370 gradually increases, and the rotation speed of the No. 1 lead screw 140 gradually increases. The distance that the No. 1 lead screw 140 drives the tool seat 130 to move also produces an integral effect, and the pitch generated by the tool 150 on the metal easel component becomes larger and larger, producing a variable pitch effect.

[0036] The rotation speed of the second lead screw 180 is transmitted to the gear seat 350 through the first bevel gear 210 and the second bevel gear 220, and the conical friction wheel 450 transmits the rotation speed of the conical friction wheel 450 to the second spline shaft 430 through the friction wheel 440, and the second spline shaft 430 transmits the rotation speed to the second lead screw 380 through the universal joint 500. When the second lead screw 380 rotates, it drives the feed seat 310 to move to the left, and the feed seat 310 drives the front side of the rocker rod 330 to move to the left, and the angle between the axis of the feed seat 310 and the axis of the first spline shaft 190 gradually increases, thereby achieving a variable pitch effect, and the output speed of the second spline shaft 430 can be changed by rotating the third lead screw 460, so that the size of the pitch change is changed, and the purpose of processing different variable pitch metal easel components is achieved. The components of the present application work together, the operation is stable, and slipping is prevented. The dimensional accuracy of the thread is accurate, and the purpose of processing different variable pitch metal easel components is achieved.

[0037] A method for using a metal easel component processing device comprises the following steps: a first step, when using the device, the metal easel component is clamped in a chuck 170, and a tail cone 160 is pressed against a center hole of the metal easel component; a second step, starting a motor 230, the motor 230 drives a second lead screw 180 and a first bevel gear 210 to rotate, the second lead screw 180 drives the chuck 170 and the metal easel component to rotate through a belt, the first bevel gear 210 drives the second bevel gear 220 to rotate, the rotation of the second bevel gear 220 drives a conical friction wheel 450 to rotate, the rotation of the conical friction wheel 450 drives a friction wheel 440 to rotate, the rotation of the friction wheel 440 drives a second spline shaft 430 to rotate, the second spline shaft 430 drives a second lead screw 380 to rotate through a universal joint 500, the second lead screw 380 drives a swing rod 330 to swing, the included angle between the axis of the swing rod 330 and the axis of the first spline shaft 190 gradually increases, the second lead screw 180 When rotating, it drives the gear seat 350, the rack 360, and the gear 370 to move forward. The rack 360 moves to the left side under the drive of the swing rod 330, and the gear 370 is driven to rotate. The gear 370 drives the No. 1 spline shaft 190 to rotate. The No. 1 spline shaft 190 drives the No. 1 lead screw 140 to rotate through the belt and the pulley. The No. 1 lead screw 140 drives the tool seat 130 and the tool 150 to move. The tool 150 changes the pitch thread at the turning part of the metal easel component. The adjusting screw 390 is rotated, and the adjusting screw 390 drives the adjusting seat 320 to move left and right. The angle between the axis of the swing rod 330 and the axis of the No. 1 spline shaft 190 changes. The larger the angle between the axis of the swing rod 330 and the axis of the No. 1 spline shaft 190, the larger the fixed pitch generated on the metal easel component. The No. 3 lead screw 460 can be rotated to change the output speed of the No. 2 spline shaft 430, thereby changing the size of the pitch change, thereby achieving the purpose of processing different variable pitch metal easel components. The present invention has stable operation, can reduce pitch error, and avoid a sudden increase in cutting depth, knife piercing phenomenon, or the appearance of bamboo knots.

[0038] When the axis of the swing rod 330 is parallel to the axis of the No. 1 spline shaft 190, when the rack 360 moves forward and backward, the relative position of the rack 360 and the gear 370 will not change, the rack 360 will not move in the left and right directions, and the gear 370 will not rotate. When the axis of the swing rod 330 has a certain angle with the axis of the No. 1 spline shaft 190, the gear seat 350 drives the gear 370 and the rack 360 to move forward and backward by a certain distance, and the rack 360 is driven to move to the left by the swing rod 330. The metal easel component is threaded, and the No. 2 lead screw 180 drives the gear seat 350 to move a fixed distance each time it rotates one circle. The axis of the swing rod 330 and the axis of the No. 1 spline shaft 190 are in a fixed position. The angle is fixed. When the gear seat 350 moves a fixed distance, the rack 360 moves left and right by a fixed distance driven by the rocker arm 330. The rotation speed of the gear 370 is fixed. Therefore, the thread line at this time is a fixed pitch. The fixed pitch can be changed by changing the angle between the rocker arm 330 and the first spline shaft 190. When changing the angle between the rocker arm 330 and the first spline shaft 190, the adjusting screw 390 is rotated. The adjusting screw 390 drives the adjusting seat 320 to move left and right. The angle between the axis of the rocker arm 330 and the axis of the first spline shaft 190 changes. The larger the angle between the axis of the rocker arm 330 and the axis of the first spline shaft 190, the larger the fixed pitch generated on the metal easel component. When the gear seat 350 moves forward and backward, the angle between the axis of the rocker arm 330 and the axis of the No. 1 spline shaft 190 gradually increases. Then, the distance that the rack 360 moves left and right will gradually increase at a fixed distance. The distance that the rack 360 moves left and right produces an integral effect. At this time, the rotation speed of the gear 370 gradually increases, the rotation speed of the No. 1 lead screw 140 gradually increases, and the distance that the No. 1 lead screw 140 drives the tool seat 130 to move also produces an integral effect. The pitch of the tool 150 on the metal easel component becomes larger and larger, producing a variable pitch effect. The rotation speed of the No. 2 lead screw 180 is transmitted to the gear seat 350 through the No. 1 bevel gear 210 and the No. 2 bevel gear 220. 0, the conical friction wheel 450 transmits the rotation speed of the conical friction wheel 450 to the second spline shaft 430 through the friction wheel 440, and the second spline shaft 430 transmits the rotation speed to the second lead screw 380 through the universal joint 500. When the second lead screw 380 rotates, it drives the feed seat 310 to move to the left, and the feed seat 310 drives the front side of the rocker rod 330 to move to the left. The angle between the axis of the feed seat 310 and the axis of the first spline shaft 190 gradually increases, thereby achieving a variable pitch effect. The output speed of the second spline shaft 430 can be changed by rotating the third lead screw 460, thereby changing the size of the pitch change, thereby achieving the purpose of processing different variable pitch metal easel components.
