Description

Technical Field

[0001] This utility model relates to the field of thread processing equipment technology, specifically to a quick-installation assembly for cutting tools used in threading equipment, a threading cutter head equipped with the installation assembly, and threading equipment. Background Technology

[0002] A threading machine is a mechanical tool specifically designed to create external threads on the ends of metal pipes (such as steel pipes and stainless steel pipes). One of its core components is the threading cutter. Typically, a threading machine contains multiple such cutters working together to complete the threading operation on the metal pipe.

[0003] For example, patent application number 202421811738.1 discloses a servo threading machine, which includes a support. The top of the support is provided with a threading mechanism. The threading mechanism includes a bracket, a first reducer, a rotating shaft flange, a planetary gear fixing plate, a dial, a guide shaft, a rib stripping knife position cylinder, a rebar limiting cylinder assembly, and a threading wheel spindle. The top of the bracket is provided with a first servo motor. The output ends of the first reducer and the first servo motor are connected by a key. The front end of the first reducer is provided with a rotating spindle. A support sleeve is sleeved on the outer wall of the rotating spindle. The rotating shaft flange is located between the rotating spindle and the support sleeve.

[0004] This patent improves machining accuracy through the design of the threading mechanism, ensuring that the threaded dimensions and specifications meet design requirements, reducing errors, and thus improving product quality and consistency. However, this threading equipment mainly focuses on precisely controlling the advance stroke of each set of tools within the threading mechanism during machining. Accurate control of the threading dimensions also requires ensuring that the initial position of each tool meets machining requirements before the tool advances. Therefore, there is an urgent need for a tool mounting assembly that can ensure each set of tools is quickly and accurately installed to the required position. Utility Model Content

[0005] This utility model provides a threading tool installation assembly, which can quickly install the tool and ensure that each set of tools can be installed in place and uniformly, thereby improving the machining accuracy of the threading equipment.

[0006] This utility model is achieved through the following technical solution:

[0007] In a first aspect, this utility model provides a threading tool mounting assembly, comprising a base and a tool clamping part disposed on the side of the base, and further comprising a positioning through hole opened on the base and a positioning rod that can be inserted into the positioning through hole; wherein, the tool clamping part comprises a first clamping block fixed on the base and a second clamping block movably mounted on the base, the second clamping block being able to move away from or closer to the first clamping block to adjust the clamping space between the two for accommodating the tool; when in the pre-installed state, the clamping space also includes redundant space to allow the tool to move along the installation path, the positioning rod is inserted into the positioning through hole and the positioning end on the positioning rod protrudes out of the base and is placed in the clamping space to form the end point of the installation path.

[0008] As a further improvement of this utility model, the end of the positioning rod away from the positioning end is provided with an installation limiting part, which is used to abut against the base to limit the relative position of the positioning rod in the positioning through hole.

[0009] As a further improvement of this utility model, the tool clamping part also includes a fastening part, which includes a threaded hole on the base, a threaded rod, an adjusting block arranged on the threaded rod, and a mounting hole on the second clamping block. The threaded rod is screwed into the threaded hole after passing through the mounting hole. The adjusting block contacts the mounting block in the mounting hole, so that the relevant position change of the threaded rod in the threaded hole causes the second clamping block to move away from or closer to the first clamping block.

[0010] As a further improvement of this utility model, at least one of the first clamping block and the second clamping block is provided with a third clamping block, and the third clamping block has a contact surface for restricting the tool from moving away from the base.

[0011] Secondly, this utility model provides a threading cutter disc kit, which includes a base plate, several sets of any of the above-mentioned threading cutter mounting components evenly distributed circumferentially on the base plate, and a cutter.

[0012] As a further improvement of this utility model, the threading tool mounting assembly is mounted on the base plate by an electric drive moving kit. The electric drive moving kit is used to control several sets of threading tool mounting assemblies to synchronously approach or move away from the central axis of the base plate.

[0013] Thirdly, this utility model provides a threading device, comprising a pipe clamping part, any of the above-mentioned threading cutter disc kits, a material feeding drive part that drives the pipe clamping part away from or near the threading cutter disc kits, and a processing drive part that drives the threading cutter disc kits to rotate circumferentially.

[0014] As a further improvement of this utility model, the pipe clamping part includes two sets of pipe clamping blocks, and the pipe clamping blocks are formed with arc-shaped clamping grooves. The two sets of arc-shaped clamping grooves together constitute the pipe clamping space.

[0015] As a further improvement of this utility model, the pipe clamping part includes two sets of pipe clamping blocks and an adjustment kit for controlling the movement of the two sets of pipe clamping blocks along the adjustment direction, wherein the adjustment direction is perpendicular to the pipe delivery direction.

[0016] As a further improvement of this utility model, it also includes a material feeding restriction part that is fixed in a relative position to the pipe clamping part, which includes a pipe flush baffle disposed between the pipe clamping part and the threading cutter disc assembly.

[0017] The beneficial effects of this utility model include:

[0018] (1) In the threading tool installation assembly, the positioning through holes and detachable positioning rods ensure that the tool can be installed in place every time during tool installation. This ensures high consistency of tool installation and positioning during tool replacement. After installation, the positioning rods can be removed to avoid interference and impact on the threading work, thereby improving the machining accuracy in the threading work.

[0019] (2) In this threading cutter kit, the above-mentioned threading cutter mounting assembly can ensure that the initial position of each set of cutters is consistent, while the electric drive moving assembly ensures that the moving stroke of each set of cutters is consistent. The two work together to further improve the machining accuracy of threading.

[0020] (3) In this threading equipment, the metal pipe is stably clamped by the pipe clamping part, the material delivery drive part precisely controls the delivery process of the metal pipe to the threading cutter head kit, and the processing drive part drives the threading cutter head kit to rotate at high speed, so that multiple sets of uniformly installed cutters installed on the cutter head kit work together to accurately complete the threading work at the end of the pipe. Overall, the precise control of the whole process effectively improves the dimensional accuracy and surface quality of thread processing. In the preferred structure, both sets of pipe clamping blocks can be moved by the adjustment kit, so that the clamped pipe can be offset as a whole. At the same time, with the precise installation of the initial position of the cutter and the accurate control of the electric drive moving kit, the threading equipment also has the ability to process eccentric threads, further expanding the working range of this equipment.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0030] Example 1:

[0031] This embodiment provides a threading tool mounting assembly, such as Figures 1-3 As shown, it includes a base 1, a tool clamping part 2 arranged on the side of the base 1, a positioning through hole 3 opened on the base 1, and a positioning rod 4, which can be inserted into the positioning through hole 3.

[0032] like Figures 2-3 As shown, the tool clamping part 2 includes a first clamping block 201 fixedly arranged on the base 1 and a second clamping block 202 movably mounted on the base 1. The second clamping block 202 can move away from or closer to the first clamping block 201 to adjust the clamping space 203 between them. This clamping space 203 is used to accommodate the tool A. For example, in this embodiment... Figure 4 The tool A shown includes a cutting part A01 and an assembly part A02. The assembly part A02 mainly participates in the overall assembly and installation of the tool A. Therefore, in this embodiment, the first clamping block 201 and the second clamping block 202 are mainly used to clamp and fix the assembly part A02 in the tool A to complete the assembly of the tool A.

[0033] Under the above-described threading cutter mounting assembly structure, the assembly process of cutter A is as follows:

[0034] First, the threading tool mounting assembly is in a pre-installed state, where the clamping space 203 formed by the first clamping block 201 and the second clamping block 202 also includes redundant space 204, therefore... Figure 3 Taking the perspective of [the device] as an example, the first clamping block 201 and the second clamping block 202 restrict the tool A from moving in a large range in the left and right directions, but the tool A can still move in the forward and backward directions along the installation path L1 to adjust its position; while at the same time, in the pre-installed state, such as Figures 2-3 As shown, the positioning rod 4 is inserted into the positioning through hole 3, and the positioning end 401 on the positioning rod 4 protrudes from the base 1 and is placed in the clamping space 203. At this time, the positioning end 401 is placed on the installation path L1 of the tool A and becomes the end point of the installation path L1 of the tool A. Therefore, when the tool A moves along the installation path L1 until it abuts against the positioning end 401, the tool A reaches the pre-installation positioning. Subsequently, while keeping the tool A abutting against the positioning end 401, the user can adjust the second clamping block 202 to move closer to the first clamping block 201 to reduce the clamping space 203 until the two are attached to the assembly part A02 in the tool A and form a clamping fixation, thereby completing the complete assembly of the tool A on the mounting assembly. Finally, the user can remove the positioning rod 4 to avoid it interfering with or affecting the threading operation of the tool A.

[0035] Overall, this threading tool mounting assembly, through the placement of positioning through holes 3 and detachable positioning rods 4, allows tool A to be quickly installed. After installation, positioning rods 4 can be removed, thus preventing interference with the threading process. In scenarios requiring frequent changes to different tool A specifications, this function ensures rapid replacement of different specifications of tool A with high consistency in the installation position after replacement, avoiding the need for repeated adjustments to the installation position of tool A, thereby improving the machining accuracy of the threading process.

[0036] Preferably, such as Figure 1 and Figure 3As shown, an installation limiting part 402 is provided on the end of the positioning rod 4 away from the positioning end 401. For example, in this embodiment, the installation limiting part 402 is an installation limiting block with a size larger than the diameter of the positioning through hole 3. The installation limiting part 402 is used to abut against the base 1. On the one hand, it is used to limit the insertion depth of the positioning rod 4 in the positioning through hole 3. In this embodiment, when the installation limiting part 402 abuts against the base 1, it indicates that the positioning end 401 at the other end is completely placed in the clamping space 203, effectively preventing the tool A from moving further along the installation path L1, thereby limiting the position of the tool A. That is, the installation limiting block can play the role of indicating whether the positioning rod 4 is installed in place. On the other hand, the installation limiting part 402 is easy to pinch because of its large size. After the tool A is installed, the user can remove the positioning rod 4 inserted on the base 1 by pinching the installation limiting part 402.

[0037] Preferably, such as Figure 1 As shown, the tool clamping part 2 includes a fastening part 205, which includes a threaded hole on the base 1, a threaded rod that can be screwed into the threaded hole, an adjusting block on the threaded rod away from the threaded end, and a mounting hole on the second clamping block 202. The adjusting block can contact the mounting block in the mounting hole, so that when the threaded rod's insertion depth in the threaded hole changes, it can move the second clamping block 202 away from or closer to the first clamping block 201, thereby adjusting the size of the clamping space 203. In the pre-installed state, the threaded rod's insertion depth is shallow, thus forming a redundant space 204 in the clamping space 203; subsequently, during full installation, the threaded rod's insertion depth is increased by screwing, the adjusting block moves toward the position of the first clamping block 201, and then, by contacting the mounting block, it also moves the second clamping block 202 closer, thereby reducing the clamping space 203 and completing the clamping and fixing of the tool A. This structure reduces contact between the tool A and the tool A during full installation, thereby reducing the likelihood of the tool A shifting along the installation path L1.

[0038] Preferably, such as Figures 2-3 As shown, a third clamping block 206 is provided on the second clamping block 202. The third clamping block 206 can support the assembly part A02 on the tool A, and through the clamping cooperation between its contact surface 206-1 and the side wall surface of the base 1, the tool A will not move away from the base 1 and fall off during the pre-assembly state and assembly process. Therefore, after adding this structure, when installing the tool A, the user can mainly focus on forcing the tool A and the positioning end 401 to abut against each other without having to consider the possibility of the tool A falling off the base 1. This further reduces the positioning difficulty of the tool A during pre-assembly and helps the user control the tool A to be fully installed after pre-assembly.

[0039] Example 2:

[0040] This embodiment provides a threading cutter disc kit, wherein, as shown in the example Figure 5 As shown, the kit includes a base plate B01, four sets of threading tool mounting assemblies in Embodiment 1 that are circumferentially evenly distributed on the base plate B01, and a tool A mounted on the assembly.

[0041] Preferably, the threading tool mounting assembly is mounted on the base plate B01 via an electrically driven moving kit B02. For example, the electrically driven moving kit B02 may employ readily available technology for controlling the four sets of threading tool mounting assemblies to synchronously move closer to or further away from the central axis of the base plate B01.

[0042] In the threading cutter head kit of this embodiment, on the one hand, by using the mounting component, it is ensured that the initial position of each set of cutters A remains consistent after installation; that is, after the initial installation of cutters A, the distance between each set of cutters A and the central axis remains consistent. On the other hand, by using the electric drive moving kit B02 to drive the threading cutter mounting component and the cutters A mounted on it away from or towards the central axis, it is ensured that the travel distance of each set of cutters A is more precise and more consistent. In summary, through the cooperation between the threading cutter mounting component and the electric drive moving kit B02, this threading cutter head kit ensures that when multiple sets of cutters A contact the workpiece and perform threading work, the depth of cut is consistent, thereby ensuring high machining accuracy in thread processing.

[0043] Example 3:

[0044] This embodiment provides a threading device, such as... Figure 5 As shown, it includes a pipe clamping part C01, a threading disc kit as in Embodiment 2, a feeding drive part C02, and a processing drive part C03. The feeding drive part C02 is used to drive the pipe clamping part C01 away from or near the threading disc kit, and the processing drive part C03 is used to drive the threading disc kit to perform circumferential motion.

[0045] During operation, the pipe clamping part C01 clamps and fixes the pipe, so that the end of the pipe to be processed faces the threading spool assembly; then the feeding drive part C02 drives the pipe clamping part C01 and the pipe to move toward the position of the threading spool assembly, while the processing drive part C03 drives the threading spool assembly to rotate circumferentially; after the pipe comes into contact with the cutting tool A in the threading spool assembly, the cutting tool A forms a cut on the surface of the pipe and processes the required thread.

[0046] Preferably, such as Figure 5As shown, the pipe clamping part C01 includes two sets of pipe clamping blocks C01-1, with an arc-shaped clamping groove C01-2 formed on each set of pipe clamping blocks C01-1. When clamping and fixing the pipe, the two sets of pipe clamping blocks C01-1 approach each other, and the two sets of arc-shaped clamping grooves C01-2 clamp and fix the pipe on both sides. This structure makes the clamping force of the pipe clamping blocks C01-1 on the pipe more evenly distributed, avoiding the concentration of force on a single point on the pipe, which could cause wall deformation and other damage, and greatly reducing the damage to the pipe by the pipe clamping part C01.

[0047] More preferably, such as Figures 5-6 As shown, the pipe clamping part C01 also includes an adjustment kit C01-3. For example, the adjustment kit C01-3 includes two sets of guide rod kits, and the guide rod kits are respectively installed on the outside of the two sets of pipe clamping blocks C01-1. In this structure, both sets of pipe clamping blocks C01-1 can be adjusted in position along the adjustment direction α shown in the figure, and the adjustment direction α is perpendicular to the pipe delivery direction β.

[0048] In typical threading operations, during pipe delivery, it's crucial to ensure the pipe's central axis coincides with the central axis of the threading cutter assembly. This guarantees consistent cutting depth for each set of cutters A on the pipe wall, resulting in more uniform threads. However, in the aforementioned structure, the pipe clamping unit C01 can drive the entire pipe to shift, causing its central axis to no longer coincide with the threading cutter assembly's central axis. This, in subsequent pipe processing, through the cooperation of the threading cutter mounting assembly (ensuring accurate placement of cutter A) and the electrically driven moving assembly B02 (ensuring precise displacement of cutter A), enables the threading equipment to achieve precise machining capabilities, thereby forming eccentric threads on the pipe surface.

[0049] Preferably, such as Figure 6 As shown, the threading device also includes a material feeding restriction part C04, whose relative position to the pipe clamping part C01 is fixed, thus allowing it to be driven by the material feeding drive part C02 along with the pipe clamping part C01. The material feeding restriction part C04 includes a pipe flushing baffle C04-1 disposed between the pipe clamping part C01 and the threading cutter head assembly. During operation, the pipe flushing baffle C04-1 abuts against the pipe, forcing the central axis of the pipe to coincide with or be parallel to the center line of the threading spindle, thereby preventing a decrease in thread machining accuracy.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
