Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of pipe processing fixture, more particularly to a pipe processing fixture quick centering auxiliary module. BACKGROUND
[0002] In the mutual connection between pipes, the socket joint is a commonly used connection mode, and in the current pipe socket processing mode, most of the double-station numerical control processing machine tools are used to cut and form the front and rear ends of the pipe body.
[0003] The prior art discloses a turning processing equipment with a multi-specification metal pipe clamping inner support clamp, and in specific use, the claw insert on the claw body can be replaced according to the size of the diameter of the metal pipe to be processed, so that the above-mentioned inner support clamp can clamp the metal pipe of multiple specifications, so that the metal pipes of different diameters can be processed on the turning processing equipment.
[0004] However, due to the error in the processing or installation of the clamp itself, it is difficult for us to find the difference in the installation and positioning of each clamp, so that when the clamp is tightened against the inner wall, the inner wall will be deformed due to uneven stress, the socket processing precision will be affected, the circumferential wall thickness deviation will be too large, the strength will be reduced, and the centrifugal force generated by high-speed rotation in the processing process will cause the pipe to jump radially and cause the problem of tool collision, so that the pipe yield cannot be guaranteed. UTILITY MODEL CONTENTS
[0005] The utility model aims at overcoming the deficiency of the installation difference between the clamps in the prior art, and provides a pipe processing clamp quick centering auxiliary module, which can assist in adjusting the position of the clamp and avoid the problems of inner wall deformation and excessive circumferential wall thickness deviation when the clamp is tightened against the inner wall.
[0006] To solve the above technical problems, the utility model adopts the technical scheme of:
[0007] A pipe processing clamp quick centering auxiliary module is provided, which comprises a chuck, a plurality of claw seats, a plurality of clamps and a first fastener, the plurality of claw seats are movably connected with the chuck, the plurality of claw seats are arranged along the circumference of the chuck, the first fastener is connected between the clamps and the claw seats, and the module further comprises a core mounting member for quick rigid positioning and a limiting ring, the chuck and the limiting ring are coaxially arranged, the core mounting member is connected between the chuck and the limiting ring, and the end of the clamp away from the chuck abuts against the inner ring surface of the limiting ring.
[0008] The utility model discloses a pipe processing fixture rapid centering auxiliary module, when installing, the fixture is connected with the claw base through the slight tightness of first fastener, selects the limit ring of inner ring radius slightly greater than the required clamping pipe inner ring radius, through the fixed core installation spare, the limit ring is coaxially connected with chuck, lets a plurality of fixtures all be located in the inner ring surface of limit ring, let the claw base move on the chuck, stop driving until at least one fixture and the inner ring surface of limit ring abut, through the first fastener with the claw base fixed connection of this fixture, slide the rest fixture, let all fixtures all abut on the inner ring surface of limit ring, and use the first fastener to fix the completed fixture, so that the end of fixture away from the chuck all abut with the inner ring surface of limit ring, the limit ring is added and provides rigid limit in the process of fixture adjustment, improves the concentricity between the end of fixture away from the chuck, improves the processing accuracy and yield, and the pipe is fixed through the support inside the fixture, can make the fixture when supporting the inner wall, avoid the problem of inner wall deformation and excessive thickness deviation of circumferential wall.
[0009] Further, the fixed core installation piece is clamped with the chuck. It is convenient to install and dismount the fixed core installation piece on the chuck, thereby facilitating the installation of the limit ring on the chuck.
[0010] Further, the chuck is provided with a positioning hole, and the fixed core installation piece comprises an expansion sleeve, an expansion block and a second connecting piece. The expansion sleeve is connected with the limit ring, the expansion sleeve is clamped with the positioning hole, the expansion sleeve is sleeved on the expansion block, and the second connecting piece is connected with the expansion sleeve and the expansion block respectively. When the limit ring is installed on the chuck, the expansion block is inserted into the positioning hole. There is an installation gap between the outer wall of the expansion block and the inner wall of the positioning hole. The expansion sleeve is inserted into the gap by the movement of the second connecting piece. The connection between the limit ring and the chuck is more compact, and the movement of the limit ring is avoided.
[0011] Further, the outer diameter of the expansion block gradually increases from the limit ring to the chuck along the axial direction of the expansion block. The expansion sleeve comprises a connecting ring and a plurality of elastic pieces. The connecting ring is connected with the limit ring, and the plurality of elastic pieces are circumferentially arranged on the connecting ring. The expansion block is located in the space surrounded by the plurality of elastic pieces. By tapering the expansion block, the expansion sleeve is sleeved on the middle position of the expansion block when being inserted. At this time, the expansion sleeve has not been expanded. The expansion sleeve is directly inserted into the positioning hole. Then, the expansion block is moved towards the inside of the expansion sleeve by the second connecting piece. The elastic pieces on the expansion sleeve are elastically deformed to fill the gap between the expansion sleeve and the positioning hole.
[0012] Further, the second connecting piece is rotationally connected with the expansion block, and the second connecting piece is threadedly connected with the expansion sleeve. By rotating the second connecting piece, the linear movement of the expansion sleeve or the expansion block is converted by the rotation movement of the second connecting piece through the thread, thereby facilitating the filling of the gap of the positioning hole.
[0013] Furthermore, it also includes a lifting assembly, which includes an elastic element. A base is provided in the middle of the limiting ring, and both ends of the elastic element are connected to the clamp and the base, respectively. By providing the elastic element, the elastic force provides a lifting force for adjusting the clamp, pushing the clamp outward along the center of the chuck until it contacts and is limited by the limiting ring. This ensures that the clamp remains taut with the limiting ring, providing a continuous lifting force to tighten the clamp and preventing the clamp's position from changing during the locking process using the first fastener. This further improves the concentricity of the clamp's end away from the chuck.
[0014] Furthermore, the lifting assembly also includes a first connector, a guide, and a lifting member. The first connector is connected to the base, the guide is movably connected to the first connector, and the lifting member is connected to the guide. The elastic member is sleeved on the guide, with its two ends connected to the base and the lifting member, respectively. The lifting member abuts against the clamp. By providing the first connector, guide, and lifting member, when the elastic member extends or retracts, the guide slides on the first connector, providing guidance for the extension and retraction of the elastic member, making it easier to adjust the clamp.
[0015] Furthermore, the lifting assembly also includes a second fastener. The first connector is movably connected to the base, and the second fastener is connected between the first connector and the base. By allowing the first connector to move relative to the base while simultaneously providing the second fastener, the position of the first connector can be adjusted on the base. This allows the elastic element to be separated from the clamp after the clamp has been adjusted, preventing the lifting assembly from subsequently affecting the clamp.
[0016] Furthermore, the clamp includes a mounting block and an arc plate, the arc plate being connected to the mounting block, the first fastener being connected between the mounting block and the claw seat, and the arc plate abutting against the inner ring surface of the limiting ring. By setting the arc plate, it fits more closely to the inner wall of the pipe, improving the internal support effect.
[0017] Furthermore, the mounting block is slidably connected to the claw seat, and the mounting block is provided with an adjustment groove. The first fastener passes through the adjustment groove and connects to the claw seat. This makes it easier to adjust the position of the clamp on the claw seat.

The inner ring surface can be an entire circular surface or a plurality of sector holes, and the utility model does not limit the inner ring surface.
[0034] As shown in Figure 2 It also includes jacking assembly 700, as shown in Figure 4 Jacking assembly 700 includes elastic member 710, which can be a spring, a spring piece or other existing parts with elasticity, and the middle of limit ring 600 is provided with base 610, as shown in Figure 3 A plurality of mounting holes 602 are provided on limit ring 600, and base 610 is connected with limit ring 600 through mounting hole 602. The two ends of elastic member 710 are connected with clamp 300 and base 610 respectively, and the number of jacking assembly 700 is consistent with the number of clamp 300. By setting elastic member 710, the elastic force is used to provide jacking force for the adjustment of clamp 300, and the clamp 300 is jacked to move outward along the center of chuck 100 until it is limited by limit ring 600, so that the clamp 300 always maintains the state of supporting and limiting limit ring 600, provides continuous jacking force for the clamp 300 to support and limit limit ring 600, and the position of the clamp 300 does not change during the process of fixing and locking by using first fastener 400, further improving the concentricity between the ends of clamp 300 away from chuck 100.
[0035] The working principle of the pipe machining clamp rapid centering auxiliary module of the embodiment is as follows:
[0036] In the installation, the clamp 300 is connected with the claw base 200 through the first fastener 400, the limiting ring 600 with a slightly larger inner ring radius than the required inner ring radius of the clamped pipe is selected, the inner ring radius is mainly selected according to the required opening radius of the clamp 300, the limiting ring 600 is coaxially connected with the chuck 100 through the core mounting part 500, the plurality of clamps 300 are located in the inner ring surface of the limiting ring 600, the driving mechanism is started to drive the claw base 200 to move on the chuck 100, and the driving is stopped until at least one clamp 300 abuts against the inner ring surface of the limiting ring 600, the clamp 300 is fixedly connected with the claw base 200 through the first fastener 400, the remaining clamps 300 are slid, all the clamps 300 abut against the inner ring surface of the limiting ring 600, and the first fastener 400 is used to fix the adjusted clamps 300, so that the ends of the clamps 300 away from the chuck 100 all abut against the inner ring surface of the limiting ring 600.

After the fixing is completed, the limiting ring 600 is disassembled, the pipe is internally supported by the clamps 300, and then the pipe is processed. The added limiting ring 600 provides rigid limiting for the adjustment process of the clamps 300, improves the concentricity between the ends of the clamps 300 away from the chuck 100, improves the processing precision and the yield, fixes the pipe by internally supporting the pipe through the clamps 300, makes the clamps apply uniform pressure to the inner wall of the pipe cavity when the clamps are tightened, avoids the deformation of the inner wall due to the uneven force on the inner wall, avoids the radial jumping of the pipe and the phenomenon that the thickness deviation of the circumference wall of the formed socket is too large due to the insufficient concentricity in the processing process, and improves the yield.
[0037] Embodiment two
[0038] The second embodiment of the pipe processing clamp rapid centering auxiliary module is similar to the first embodiment, and the difference lies in that, as shown in Figure 1 and Figure 2 The core mounting part 500 is clamped with the chuck 100.

[0040] The chuck 100 is provided with a positioning hole, as shown in Figure 5As shown, the core positioning fixture 500 includes a sleeve 510, an expansion block 520, and a second connecting member 530.

The sleeve 510 is directly inserted into the positioning hole, and then the expansion block 520 is moved towards the inside of the sleeve 510 by the second connecting member 530. The elastic pieces on the sleeve 510 are elastically deformed to fill the gap between the sleeve 510 and the positioning hole.
[0042] As shown in Figure 5 The second connecting member 530 is rotationally connected with the expansion block 520, and the second connecting member 530 is threadedly connected with the sleeve 510. By rotating the second connecting member 530, the linear motion of the sleeve 510 or the expansion block 520 is converted by the rotation of the second connecting member 530 through the thread, so that the gap of the positioning hole is more easily filled.
