Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing equipment technology, and in particular to an axial feed device. Background Technology

[0002] Existing pipe fitting processing equipment uses a clamping device to hold the pipe fitting, and then uses a cutting device to cut the pipe fitting radially to change the length of the pipe fitting or to bevele it. However, existing pipe fitting processing equipment can only cut the pipe fitting radially and cannot perform axial cutting, resulting in the existing pipe fitting processing equipment having a relatively limited function. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art by providing an axial feed device that can perform axial machining on pipes, thereby solving the problem that the prior art can only perform radial machining on pipes.

[0004] The technical solution of this utility model is as follows: An axial feed device includes a mounting frame, a tool holder slidably mounted on the mounting frame, and a drive assembly for driving the tool holder to slide axially on the mounting frame. The drive assembly includes a screw, a worm gear, and a worm. The worm gear and the worm are mounted on the mounting frame, and the worm gear and the worm cooperate with each other. The end of the worm extending out of the mounting frame is provided with a drive component for driving the worm to rotate. The screw is vertically mounted on the mounting frame and rotates synchronously with the worm gear. The tool holder is directly or indirectly threadedly engaged with the screw so that the tool holder slides axially on the screw when the screw rotates.

[0005] Using the above technical solution, the driving component drives the worm gear to rotate, which in turn drives the worm wheel and screw to rotate. The tool holder slides on the screw, changing the height position of the cutting tool, so that it can be processed along the axial direction of the pipe. Specifically, the driving component is a rotating wheel with a toothed outer circumference and a stop. The rotating wheel can cooperate with the stop to form the screw rotation. Specifically, the rotating wheel moves with the rotating seat to the stop position and touches the stop. At this time, the rotating wheel is passively rotated by a certain angle. When the rotating disk moves to this position again and touches the stop again, the rotating wheel is passively rotated by a certain angle again, and so on, so that it can be processed sequentially along the axial direction of the pipe.

[0006] A further feature of this invention is that the tool holder has an open mounting cavity on one side, and a nut is provided in the mounting cavity. The nut is sleeved on the screw and threadedly engaged with the screw to allow the tool holder to slide axially on the screw.

[0007] With the above-mentioned further configuration, the nut and the screw are threaded together. When the screw rotates, the nut slides axially on the screw and drives the tool holder to slide, making the machining more convenient and eliminating the need for thread machining on the tool holder.

[0008] A further feature of this invention is that the tool holder includes a separate base and a slider. The base has a first groove along its transverse direction, and the slider is slidably disposed in the first groove. The base also has a threaded hole, and the slider is connected to a threaded rod that mates with the threaded hole. The threaded rod rotates to drive the slider to slide in the first groove.

[0009] With the above further settings, the position of the cutting blade can be adjusted to change the cutting depth. It can be adjusted according to the needs. When adjusting, rotating the threaded rod will drive the slider to slide on the base, which is convenient. The slider is provided with a connecting groove, and the end of the threaded rod is located in the connecting groove.

[0010] A further feature of this invention is that the mounting bracket is provided with a guide groove along its vertical direction, and the tool holder is provided with a guide slider, which is slidably disposed within the guide groove.

[0011] With the above-mentioned further design, the tool holder becomes more stable when sliding along the vertical direction of the mounting bracket.

[0012] A further improvement of this utility model: the mounting bracket consists of a first mounting plate, a second mounting plate, and a cover plate, which are separately arranged. The first mounting plate and the second mounting plate are arranged perpendicularly and connected to each other. A guide groove is provided on the first mounting plate. The second mounting plate has a first mounting groove and a second mounting groove that are recessed downwards and communicate with each other. The worm gear is located in the first mounting groove, and the worm wheel is located in the second mounting groove. The cover plate is connected to the second mounting plate and covers the two mounting grooves. The cover plate has a through hole for the screw to pass through.

[0013] With the above-mentioned further design, the split design facilitates the installation of each component. The two mounting plates and the cover plate are connected and fixed to the second mounting plate by screws. The cover plate also has a mounting groove corresponding to the position of the worm gear, providing space for the worm gear to move. The structure is compact. At the same time, the cover plate can cover the worm gear, making it not exposed, which is more aesthetically pleasing, and also prevents other debris from entering and affecting the operation of the worm gear.

[0025] like Figure 1-6As shown, an axial feed device includes a mounting frame 1, a tool holder 2 slidably mounted on the mounting frame 1, and a drive assembly 3 for driving the tool holder 2 to slide axially on the mounting frame 1. The drive assembly 3 includes a screw 31, a worm gear 32, and a worm 33. The worm gear 32 and worm 33 are mounted on the mounting frame 1, and the worm gear 32 cooperates with the worm 33. The end of the worm 33 extending outside the mounting frame 1 is provided with a drive member 34 for driving the worm 33 to rotate. The screw 31 is vertically mounted on the mounting frame 1 and rotates synchronously with the worm gear 32. A connecting block 11 is provided at the upper end of the mounting frame 1, and the upper end of the screw 31 is rotatably mounted on the connecting block 11 through a bearing. The tool holder 2 is directly or indirectly threadedly engaged with the screw 31 so that the tool holder 2 slides axially on the screw 31 when the screw 31 rotates. The driving component 34 drives the worm gear 33 to rotate, which in turn drives the worm wheel 32 and the screw 31 to rotate. The tool holder 2 slides on the screw 31, changing the height position of the cutting tool, so that it can be processed along the axial direction of the pipe. The specific driving component is a rotating wheel with a toothed outer circumference. A stop is also provided. The rotating wheel can cooperate with the stop to make the screw 31 rotate. Specifically, the rotating wheel moves with the rotating seat to the stop position and touches the stop. At this time, the rotating wheel is passively rotated by a certain angle. When the rotating disk moves to this position again and touches the stop again, the rotating wheel is passively rotated by a certain angle again. This process is repeated to process the pipe along the axial direction. Of course, other driving components, such as motors or rotary cylinders, can also be used to drive the screw 31 to rotate.

[0026] The tool holder 2 is provided with a mounting cavity 21 with an open side. A nut 4 is provided in the mounting cavity 21. The nut 4 is sleeved on the screw 31 and threaded with the screw 31 to allow the tool holder 2 to slide axially on the screw 31. Through the threaded engagement between the nut 4 and the screw 31, when the screw 31 rotates, the nut 4 slides axially on the screw 31 and drives the tool holder 2 to slide, making the processing more convenient and eliminating the need for thread processing on the tool holder 2.

[0027] The cutter holder 2 includes a split base 22 and a slider 23. The base 22 has a first groove 221 along its transverse direction. The slider 23 is slidably disposed in the first groove 221. The base 22 also has a threaded hole. The slider 23 is connected to a threaded rod 5 that mates with the threaded hole. The threaded rod 5 rotates to drive the slider 23 to slide in the first groove 221. The slider 23 has a connecting groove, and the end of the threaded rod is located in the connecting groove, which can adjust the position of the cutting blade to change the cutting depth. It can be adjusted according to the needs. When adjusting, rotating the threaded rod can drive the slider 23 to slide on the base 22. The adjustment is convenient. The slider 23 has a connecting groove, and the end of the threaded rod is located in the connecting groove.

[0028] The mounting bracket 1 is provided with a guide groove 12 along its vertical direction, and the tool holder 2 is provided with a guide slider 24. The guide slider 24 is slidably disposed in the guide groove 12, making the structure of the tool holder 2 more stable when it slides along the vertical direction of the mounting bracket 1. The mounting bracket 1 consists of a first mounting plate 13, a second mounting plate 14, and a cover plate 15, which are arranged in separate parts. The first mounting plate 13 and the second mounting plate 14 are vertically arranged and connected to each other. A guide groove 12 is provided on the first mounting plate 13. The second mounting plate 14 has a first mounting groove 141 and a second mounting groove 142 that are recessed downwards and communicate with each other. The worm 33 is located in the first mounting groove 141, and the worm wheel 32 is located in the second mounting groove 142. The cover plate 15 is connected to the second mounting plate 14 and covers the two mounting grooves. The cover plate 15 has a through hole for the screw 31 to pass through. The separate arrangement facilitates the installation of each component. The two mounting plates and the cover plate 15 are fixed to the second mounting plate 14 by screws. The cover plate 15 also has a mounting groove corresponding to the position of the worm wheel and worm, providing space for the worm wheel and worm to move. The structure is compact. At the same time, the cover plate 15 can cover the worm wheel and worm, making it less exposed and more aesthetically pleasing. It also prevents other debris from entering and affecting the operation of the worm wheel and worm.
