Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping fixture for a pipe cutting machine. Background Technology

[0002] Special conduits, such as circular conduits with an internal diaphragm, are typically processed by clamping them to the outside of the conduit to fix them in place before using cutting tools for shaping and other processing. Because the conduit is not transparent, it is not easy to position it relative to the diaphragm during processing. Utility Model Content

[0003] The purpose of this utility model is to provide a pipe cutting machine clamp to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a pipe-cutting machine clamp for clamping a conduit with an internal diaphragm, the diaphragm dividing the interior of the conduit into a first cavity and a second cavity. The pipe-cutting machine clamp includes: a base with a limiting groove on the top for inserting a portion of the conduit; a shaft seat rotatably mounted on one end of the base, the shaft seat having a first semi-cylinder that can be adapted to be inserted into the first cavity and a second semi-cylinder that can be adapted to be inserted into the second cavity; a first driving member for driving the shaft seat to rotate; and a limiting clamp mounted on the end of the base away from the shaft seat, the limiting clamp being used to limit the position of the conduit away from the shaft seat.

[0005] This technical solution has at least the following beneficial effects: The end of the conduit requiring machining is inserted into the first and second semi-cylinders, allowing the first semi-cylinder to insert into and support the first cavity, and the second semi-cylinder to insert into and support the second cavity. A limiting clamp then restricts the other end of the conduit, thus stabilizing its position and facilitating machining. Since the diaphragm is located between the first and second semi-cylinders, precise positioning of the diaphragm is easily achieved. Furthermore, the support of the first and second semi-cylinders prevents deformation, ensuring machining quality and reducing defective products.

[0006] As a further improvement to the above technical solution, a locking block is provided at one end of the second semi-cylinder, and the bearing seat has a slot for the locking block to be inserted in a direction perpendicular to the axis of the second semi-cylinder, so that the locking block cannot be dislodged from the slot in the direction of the axis of the second semi-cylinder.

[0007] As a further improvement to the above technical solution, the cross-section of the card block is T-shaped or dovetail-shaped.

[0008] As a further improvement to the above technical solution, the second semi-cylinder is a flexible block.

[0009] As a further improvement to the above technical solution, the limiting clamp includes a lower plate, an upper plate vertically slidably disposed on the base, and a second driving member for driving the upper plate to slide. An upper clamping block is provided at the bottom of the upper plate, and a first groove is provided at the bottom of the upper clamping block. A lower clamping block is provided at the top of the lower plate, and a second groove is provided at the top of the lower clamping block. The upper clamping block and the lower clamping block are staggered.

[0010] As a further improvement to the above technical solution, the upper plate is provided with at least two upper clamping blocks at intervals, and the lower plate is provided with at least two lower clamping blocks at intervals, with the at least two upper clamping blocks and the at least two lower clamping blocks being staggered.

[0011] As a further improvement to the above technical solution, both sides of the first groove and the second groove are inclined surfaces and are both rolled with balls that can abut against the conduit.

[0012] As a further improvement to the above technical solution, the upper plate is provided with a sliding groove, a slider is slidably arranged in the sliding groove, and the upper plate is provided with an elastic element that can push the slider to contact the guide tube.

[0013] As a further improvement to the above technical solution, a limiting block is provided at the top of the slider to limit the depth of the slider extending into the groove.

[0014] As a further improvement to the above technical solution, the second driving component includes a screw rotatably mounted on the base and a second motor for driving the screw to rotate, wherein the screw is threadedly connected to the upper plate. Attached Figure Description

[0026] The pipe cutting machine fixture is used to hold the pipe to be cut. The pipe has a diaphragm inside, which divides the inside of the pipe into a first cavity and a second cavity. The cross-section of the first cavity and the second cavity is semi-circular.

[0027] A drive slide rail is mounted on the cutting table, and the pipe cutter fixture is mounted on the drive slide rail, allowing the drive slide rail to move the pipe cutter fixture back and forth. A cutting tool is mounted on the top of the cutting table, and the pipe held by the pipe cutter fixture can be cut by the cutting tool. The cutting tool can be changed to perform specific machining on the pipe.

[0028] Reference Figure 1-5 The pipe cutting machine fixture includes a base 100, a shaft seat 200, a first drive component 300, and a limit clamp 400.

[0029] The base 100 includes a support plate 110, a first fixing block 120, and a second fixing block 130. The support plate 110 is mounted on the drive slide rail of the cutting table. The first fixing block 120 and the second fixing block 130 are bolted to the top surface of the support plate 110, and the first fixing block 120 and the second fixing block 130 are arranged side by side with a certain gap between their adjacent ends. A stepped straight groove is formed on the top of the first fixing block 120, and a bearing seat 200 is rotatably mounted on the side wall of the stepped straight groove of the first fixing block 120. The bearing seat 200 is equipped with a first semi-cylinder 210 and a second semi-cylinder 220, both of which have semi-circular cross-sections, and the arc surface of the first semi-cylinder 210 is opposite to the arc surface of the second semi-cylinder 220. The distance between the first semi-cylinder 210 and the second semi-cylinder 220 is equal to or slightly greater than the thickness of the inner diaphragm of the conduit. The first fixing block 120 has a limiting groove 140 on the bottom wall of its stepped straight groove, and the second fixing block 130 also has a limiting groove 140 on its top surface. The side wall of the limiting groove 140 of the first fixing block 120 is a semi-circle that fits the outer wall of the conduit. The side wall of the limiting groove 140 on the top surface of the second fixing block 130 is a square groove, and both sides of the square groove are provided with inclined chamfers to support the conduit.

[0030] The first driving component 300 is a first driving motor. The first driving motor is mounted on the support plate 110. The output end of the first driving motor extends into the first fixed block 120 and is connected to the shaft seat 200, so that the first driving motor can drive the shaft seat 200 to rotate, thereby driving the first semi-cylinder 210 and the second semi-cylinder 220 to rotate synchronously.

[0031] During the processing of the conduit, the conduit can be inserted into the first semi-cylinder 210 and the second semi-cylinder 220, so that the first semi-cylinder 210 can be inserted into the first cavity of the conduit for positioning, and the second semi-cylinder 220 can be inserted into the second cavity of the conduit for positioning. The lower half of the conduit is located in the limiting groove 140, so that the side wall of the limiting groove 140 can initially restrict the position of the conduit, facilitating the clamping and positioning operation of the conduit. The diaphragm of the conduit is located in the gap between the first semi-cylinder 210 and the second semi-cylinder 220, thereby positioning and clamping the conduit. After the limiting clamp 400 restricts the other end of the conduit, the first drive motor drives the shaft seat 200 to rotate, thereby driving the conduit to rotate and perform processing operations on different parts of the conduit. The rotational stability of the conduit is good and the processing accuracy is high. Moreover, with the support of the first semi-cylinder 210 and the second semi-cylinder 220, the conduit is not easily deformed, thus ensuring the processing quality of the conduit and reducing the generation of defective products.

[0032] Furthermore, a locking block 211 is provided at one end of the second semi-cylinder 220 near the bearing seat 200. The locking block 211 and the second semi-cylinder 220 are integrally formed and made of flexible blocks such as silicone. The first semi-cylinder 210 is integrally formed with the bearing seat 200 using hard blocks such as plastic or steel. A slot 201 is provided on the side wall of the bearing seat 200. When assembling the second semi-cylinder 220 and the bearing seat 200, the locking block 211 is inserted into the slot 201 in a direction perpendicular to the axis of the clamped conduit. This prevents both the locking block 211 and the second semi-cylinder 220 from dislodging from the slot 201 in a direction perpendicular to the axis of the conduit, ensuring the stable connection between the second semi-cylinder 220 and the bearing seat 200 and simplifying assembly. In addition, after the locking block 211 is inserted into the slot 201, the locking block 211 protrudes from the outer side wall of the bearing seat 200 and engages with the side wall of the bearing seat 200 to form a cylindrical shape. During the tube cutting process, the second semi-cylinder 220 may be damaged or scratched. By replacing the second semi-cylinder 220, the tube to be processed can be continuously and accurately positioned and clamped.

[0033] Furthermore, the cross-section of the locking block 211 is T-shaped or dovetail-shaped, and the narrower end is connected to the second semi-cylinder 220. This prevents both the locking block 211 and the second semi-cylinder 220 from dislodging from the slot 201 along the axis perpendicular to the conduit.

[0034] Specifically, the limit clamp 400 includes an upper plate 500, a lower plate 600, and a second drive component 700.

[0035] The lower plate 600 is mounted on the support plate 110, and is positioned at the end of the second fixing block 130 away from the first fixing block 120. Multiple guide rods 530 are provided on the support plate 110 at the position away from the second fixing block 130 on the lower plate 600. A sliding plate is slidably mounted on the multiple guide rods 530. Two insertion posts are provided on one side of the sliding plate. The upper plate 500 has two insertion holes for inserting the two insertion posts. By inserting the two insertion posts into the two insertion holes respectively, the upper plate 500 can be connected to the sliding plate, allowing the upper plate 500 and the support plate 110 to slide vertically relative to each other.

[0036] A top plate is mounted on the top of multiple guide rods 530, and a bottom plate is mounted on the bottom of multiple guide rods 530. The bottom plate is mounted on the support plate 110. The second drive unit 700 includes a screw 710 and a second motor 720. The second motor 720 is mounted on the top plate, with its output end facing downwards and connected to the top of the screw 710. Both ends of the screw 710 are rotated in the top plate and bottom plate respectively via bearings. The screw 710 passes through a sliding plate and is threadedly connected to the sliding plate. The second motor 720 can drive the screw 710 to rotate, thereby causing the screw 710 to drive the sliding plate to slide up and down, thus driving the upper plate 500 to slide up and down.

[0037] The upper plate 500 is positioned above the lower plate 600. Two or more upper clamping blocks 510 are arranged side-by-side along the axis of the clamped conduit at the bottom of the upper plate 500. Each upper clamping block 510 has a first groove 520 extending through both sides at its bottom. Both sides of the first groove 520 are inclined surfaces, resulting in a cross-section that is either an inverted V-shape or a frustum-shaped cone. Roller balls 540 are tumbling-mounted on both inclined surfaces of the first groove 520.

[0038] Two or more lower clamping blocks 610 are arranged side by side on the top of the lower plate 600 along the axis of the clamped conduit. A second groove 620 is formed on the top of each lower clamping block 610, extending through both sides. Both sides of the second groove 620 are inclined surfaces, resulting in a cross-section of the second groove 620 that is inverted V-shaped or frustum-shaped. Ball bearings 540 are rolled onto both inclined surfaces of the second groove 620.

[0039] The upper clamping blocks 510 are spaced apart, with the distance between them equal to or slightly greater than the thickness of the lower clamping block 610. The lower clamping blocks 610 are also spaced apart, with the distance between them equal to or slightly greater than the thickness of the upper clamping block 510. Each upper clamping block 510 and its corresponding lower clamping block 610 are staggered along their thickness direction.

[0040] When the second motor drives the screw 710 to rotate, it can cause the upper plate 500 to slide downward, thereby clamping the conduit between the first groove 520 and the second groove 620. The balls 540 on both sides of the first groove 520 and the second groove 620 abut against the side wall of the conduit, thereby limiting the conduit while reducing frictional resistance to the rotation of the conduit.

[0041] In other embodiments, the second drive unit 700 may also be a telescopic cylinder such as a pneumatic cylinder, hydraulic cylinder or electric cylinder. The telescopic cylinder is mounted on the top plate, and the output end of the telescopic cylinder passes through the top plate and is fixedly connected to the slide plate, so that the slide plate can be driven to slide up and down by driving the telescopic cylinder.

[0042] Furthermore, the upper plate 500 has a through groove 800 extending vertically, and a slider 810 passes through the groove 800. A limiting block 900 is provided on the top of the slider 810, and the diameter of the limiting block 900 is larger than the diameter of the groove 800. An elastic element 820, which is a helical spring, is installed on the upper plate 500. One end of the helical spring is fixedly connected to the upper plate 500, and the other end is connected to the top of the slider 810. The elastic force of the helical spring can push the slider 810 downward, so that the slider 810 is inserted into the deepest position of the groove 800 and is restricted by the limiting block 900, that is, the limiting block 900 presses against the top of the upper plate 500. At this time, the bottom part of the slider 810 extends to a position below the upper plate 500, and the bottom height of the slider 810 is lower than the highest position of the first groove 520.

[0043] When the second drive motor rotates the screw 710, it causes the upper plate 500 to slide downwards, thus clamping the conduit between the first groove 520 and the second groove 620. The balls 540 on both sides of the first and second grooves 520 abut against the sidewalls of the conduit. Simultaneously, the bottom of the slider 810 is pressed against the conduit by the elastic force of the elastic element 820, further ensuring the stability of the conduit. This facilitates machining operations on the conduit using cutting tools.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
