Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figure 1-9 As shown, a machining lathe in one embodiment of the present invention includes: a worktable 1 and a feeding device 2.

[0034] As shown in the figure, a base 101 is fixed on the workbench 1, and a support 102 is fixed on the base 101. A pipe 103 is slidably mounted on the support 102. When using this device, a clamping device needs to be connected to one side of the pipe 103 to clamp the pipe to be processed. A first gear 105 is fixed on the pipe 103 to drive the pipe 103 to rotate. A first drive shaft 104 and a second drive shaft 111 are mounted on the base 101. The first drive shaft 104 needs to be driven by an external drive device to rotate. A second gear 106 is fixed on the first drive shaft 104, and a fourth gear 108 is fixed on the end of the second drive shaft 111 near the second gear 106.

[0035] like Figure 1-5 As shown, a pair of arc-shaped grooves 109 are fixed on the support member 102. The rotating shaft 110 slides along the trajectory of the arc-shaped grooves 109. The arc of the arc-shaped grooves 109 is centered on the first transmission shaft 104, so that when the rotating shaft 110 slides in the arc-shaped grooves 109, the third gear 107 and the second gear 106 are always in a meshing state.

[0036] like Figure 1-5As shown, a rotating shaft 110 is slidably mounted on the arc-shaped slide groove 109. A third gear 107 is installed on the rotating shaft 110. The second gear 106 drives the first gear 105 or the fourth gear 108 to rotate through the third gear 107. When the second gear 106 rotates counterclockwise, the rotational force of the second gear 106 drives the rotating shaft 110 to the upper end of the arc-shaped slide groove 109 through the third gear 107, causing the third gear 107 to mesh with the first gear 105 and drive it to rotate. When the second gear 106 rotates counterclockwise, the rotational force of the second gear 106 drives the rotating shaft 110 to the lower end of the arc-shaped slide groove 109 through the third gear 107, causing the third gear 107 to mesh with the fourth gear 108 and drive it to rotate. The third gear 107 can mesh with the first gear 105, the second gear 106, and the fourth gear 108. The second gear 106 drives the first gear 105 or the fourth gear 108 to rotate through the third gear 107.

[0037] like Figure 4-9 As shown, the feeding device 2 is installed on the workbench 1. The feeding device 2 includes a pair of slide rails 201, on which a slider 202 is slidably mounted. A push block 206 is fixed on the slider 202. The slider 202 drives the push block 206 to slide on the slide rails 201, causing the push block 206 to push the pipe in the storage box 203 into the pipe 103. A lead screw 204 is provided between the base 101 and the side wall of the workbench 1. A threaded sleeve 211 is threadedly connected to the lead screw 204. The threaded sleeve 211 is slidably mounted inside the slider 202. Rotating the lead screw 204 causes the threaded sleeve 211 to move the slider 202. A storage box 203 is installed on the workbench 1 for placing the pipes to be processed.

[0038] like Figure 4-9 As shown, a pair of first springs 209 are installed between the slider 202 and the side wall of the worktable 1. The elastic force provided by the first springs 209 pulls the slider 202 closer to the sixth gear 208. The sixth gear 208 is fixed to the end of the second drive shaft 111 away from the fourth gear 108, and the fifth gear 207 is fixed to the end of the lead screw 204 near the sixth gear 208. The sixth gear 208 and the fifth gear 207 mesh with each other. The second drive shaft 111 drives the sixth gear 208 to rotate, the sixth gear 208 drives the fifth gear 207 to rotate, and the fifth gear 207 drives the lead screw 204 to rotate. A retaining ring 212 is fixed on the threaded sleeve 211. A groove 213 is cut into the retaining ring 212, and the groove 213 is used to hold the retaining block 214.

[0039] like Figure 4-9As shown, a pair of second control rods 215 are inserted into the slider 202. The second control rods 215 are used to drive the locking block 214 to move, so that the locking block 214 is locked in the slot 213 or moves out of the slot 213. The pair of second control rods 215 are fixed with the locking block 214 in the slider 202. The locking block 214 is set in the slot 213. By locking the locking block 214 in the slot 213, the threaded sleeve 211 is fixed together with the slider 202.

[0040] like Figure 4-9 As shown, a pair of second control levers 215 each have a first control lever 205 inserted at one end near the fifth gear 207. The first control lever 205 is used to push the second control lever 215. A second spring 210 is installed between the inner walls of the first control lever 205 and the second control lever 215. The elastic force provided by the second spring 210 can push the first control lever 205 and the second control lever 215 against each other. A discharge groove 216 is cut at one end of the storage box 203 near the push block 206. The push block 206 passes through the discharge groove 216 to push the pipe in the storage box 203 into the pipe 103.

[0041] Working principle: First, before using this device, a clamping device needs to be connected to one side of the pipe 103. The first drive shaft 104 is driven by an external drive device to rotate. Then, the pipe fitting to be processed is placed into the storage box 203. Before using this device, the clamping block 214 is locked in the slot 213. Then, the drive device at the first drive shaft 104 is started to drive the first drive shaft 104 to rotate clockwise. The first drive shaft 104 drives the second gear 106 to rotate clockwise. The second gear 106 drives the rotating shaft 110 to the lower end of the arc-shaped slide groove 109 through the third gear 107, so that the third gear 107 meshes with the fourth gear 108 and drives the fourth gear 108 to rotate. The fourth gear 108 drives the sixth gear 208 to rotate through the second drive shaft 111. The sixth gear 208 drives the lead screw 204 to rotate through the fifth gear 207.

[0042] Since the locking block 214 is initially locked in the slot 213, the threaded sleeve 211 and the slider 202 are fixed together. When the screw 204 is rotated, the screw 204 drives the slider 202 to move towards the base 101. The slider 202 drives the push block 206 to move towards the base 101. During the movement of the push block 206, the pipe in the storage box 203 is pushed into the pipe 103. After the slider 202 moves towards the base 101 and the second control rod 215 contacts the base 101, the slider 202 continues to move towards the base 101. The base 101 pushes the second control rod 215. The second control rod 215 drives the locking block 214 to slowly move out of the slot 213. When the locking block 214 is completely moved out of the slot 213, the threaded sleeve 211 and the slider 202 are in a sliding state, and the pipe has been pushed into the pipe 103, so the drive device is turned off.

[0043] When the lead screw 204 stops rotating, the tension of the first spring 209 pulls the slider 202 closer to the fifth gear 207. When the first control lever 205 contacts the side wall of the worktable 1, one possibility is that the locking block 214 is aligned with the slot 213. In this case, the first control lever 205 pushes the second control lever 215, and the second control lever 215 causes the locking block 214 to lock into the slot 213, thus fixing the threaded sleeve 211 and the slider 202 in a fixed state again. Another possibility is that the locking block 214... 4. If the slot 213 is not aligned, the first control lever 205 slides into the second control lever 215, while compressing the second spring 210. When the lead screw 204 rotates again, since the threaded sleeve 211 and the slider 202 are in a sliding state, the rotation of the lead screw 204 will drive the threaded sleeve 211 to rotate. When the threaded sleeve 211 rotates until the locking block 214 is aligned with the slot 213, the rebound force of the second spring 210 pushes the second control lever 215, locking the locking block 214 in the slot 213.

[0044] Then, the pipe is clamped and fixed using an external clamping device on one side of pipe 103. The drive unit is then activated, causing the first transmission shaft 104 to rotate counterclockwise. The second gear 106, through the third gear 107, drives the rotating shaft 110 to the upper end of the arc-shaped slide groove 109, causing the third gear 107 to mesh with the first gear 105 and rotate. The first gear 105 then rotates pipe 103, allowing a cutting tool to be used to machine the pipe diameter. This process is repeated until the pipe diameter is reached.
