Description

Technical Field

[0001] This utility model relates to the field of PPR pipe production technology, and in particular to a positioning device for PPR pipe production. Background Technology

[0002] PPR pipe is a type of polymer pipe. During production and processing, the pipe needs to be clamped and fixed. Therefore, a positioning device for PPR pipe production (publication number CN215617697U) is described. The positioning device is installed and fixed via a mounting plate. During installation and removal, a pull ring is used to pull the positioning rod on the fixing bracket outwards, causing one end of the positioning rod to disengage from the positioning hole of the fixing seat. Then, the fixing seat is removed upwards. During installation, the fixing seat is placed in the mounting seat, the pull ring is released, and the positioning rod inserts into the positioning hole under the elastic force of the return spring, achieving quick installation and removal of the positioning device. A cylinder presses the second clamping plate downwards, causing it to descend on the fixing column via the connecting seat. This, in turn, clamps and fixes the pipe through the first and second clamping plates. Anti-slip pads are used to improve the stability of the pipe during positioning.

[0003] However, in the existing technology, the second clamp is fixed directly above the mounting base and cannot be removed. This design may hinder the operator from installing and removing the pipe when positioning and supporting the middle section of the pipe. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a positioning device for PPR pipe production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning device for PPR pipe production, comprising a fixed base, wherein two sliding seats arranged horizontally are slidably installed on the upper surface of the fixed base, and two anti-slip pads are fixedly installed in the middle of the upper surface of the fixed base. The two anti-slip pads are arranged parallel to the sliding seats and are used to support the bottom of the pipe. Two L-shaped seats are symmetrically fixedly installed on the top plate of the sliding base. A clamping arm that swings up and down is hinged inside the L-shaped seat. The clamping arm and one side of the L-shaped seat rotate through the L-shaped seat and extend outward and are fixedly installed with a swing gear. A straight rack is inserted into the upper surface of the sliding base at the position of each swing gear. The ends of the two straight racks on the same sliding base are opposite each other and respectively mesh with the adjacent swing gear. L-shaped racks are fixedly installed at the opposite ends of the two straight racks on the same sliding base. The two L-shaped racks are arranged in a ring array about the center of the upper surface of the sliding base, and a steering gear that meshes with the tooth surface of the two L-shaped racks is rotatably connected at the center of the upper surface of the sliding base.

[0006] Preferably, the upper surface of the fixed seat is rotatably connected to a recessed bidirectional screw, and the two ends of the bidirectional screw are respectively threaded through and connected to the opposite surfaces of the two sliding seats.

[0007] Preferably, the clamping arm is rotatably connected to a threaded rod, one end of which faces the rotating end of the clamping arm and is threadedly connected to a winch that is inserted into the inside of the clamping arm. A motor located in an L-shaped seat and used to drive the threaded rod to rotate is fixedly installed at one end of the clamping arm.

[0008] Preferably, a binding strap is wound around the winding spool inside the winch, and a connecting piece is fixedly installed on one side of the binding strap. Two connecting pieces on the two sliding seats located on the same side of the fixed seat are connected by bolts.

[0009] Preferably, one end of one of the straight racks on each sliding seat is fixedly mounted with an insert plate, and an insert rail is inserted into the insert plate and is arranged perpendicular to the opposite surfaces of the two sliding seats.

[0010] Preferably, the two insertion rails are arranged in parallel and the bottom edge of the insertion rails is fixedly installed with an insertion strip that is embedded in one side of the upper surface of the fixed seat. A hydraulic rod is provided between the insertion strip and the fixed seat.

[0011] Preferably, the clamping arm is frame-shaped, and the winch housing portion is inserted into the inner side of the clamping arm.

[0012] Preferably, the two vertical sides of the L-shaped seats on the same sliding seat are both located close to the center of the sliding seat, and the inner side of the vertical side of the L-shaped seat is used to abut against the clamping arm.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, two anti-slip pads are set to support and lift the bottom edge of the pipe, and two swing gears on the sliding seat rotate upward at the same speed to a vertical state. Then, the two sliding seats move relative to each other, and the vertical clamping arm clamps the surface of the pipe from the side. In this solution, the clamping arm can swing down to be misaligned with the pipe. Therefore, when supporting and positioning the middle section of the pipe, the clamping arm can be swung down to a horizontal position to facilitate the direct removal of the pipe.

[0015] 2. In this utility model, when the clamping arm abuts against the pipe, the position of the winch is adjusted to avoid contact interference between the winch and the surface of the pipe. The binding strap is released by the winch, and the connecting pieces on the two binding straps located on the front and rear sides of the fixing seat are connected and fixed by bolts. Then, the binding strap is wound up by the winch, so that the two connected pieces can press against the top edge of the outer surface of the pipe, thus pressing the pipe from above and further fixing the position of the pipe.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-4 As shown, a positioning device for PPR pipe production includes a fixed base 1. Two sliding seats 5 arranged horizontally are slidably installed in the upper surface of the fixed base 1, and two anti-slip pads 4 are fixedly installed in the middle of the upper surface of the fixed base 1. The two anti-slip pads 4 are arranged parallel to the sliding seats 5 and are used to support the bottom of the pipe. A recessed bidirectional screw 6 is rotatably connected to the upper surface of the fixed base 1. The two ends of the bidirectional screw 6 pass through the opposite surfaces of the two sliding seats 5 and are threadedly connected. In actual use, the bidirectional screw 6 is driven to rotate by installing a stepper motor 17 outside the fixed base 1, so that the two threaded sliding seats 5 can move relative to each other or towards each other, which is convenient for adjustment according to the diameter of the pipe. In addition, when the pipe is placed on the fixed base 1, the pipe is placed between the two anti-slip pads 4, and the anti-slip pads 4 are arranged parallel to the central axis of the pipe.

[0025] Two L-shaped seats 18 are symmetrically fixedly installed on the top plate of the sliding seat 5. Clamping arms 7 that swing up and down are hinged within the L-shaped seats 18. The vertical sides of the two L-shaped seats 18 on the same sliding seat 5 are positioned close to the center of the sliding seat 5, and the inner surfaces of the vertical sides of the L-shaped seats 18 are used to abut against the clamping arms 7. In the retracted state, the clamping arms 7 are horizontal; in the use state, the clamping arms 7 are vertical, with one side of the clamping arm 7 pressing firmly against the vertical side of the L-shaped seat 18. This allows for the application of torque to the clamping arms 7, ensuring a tight contact between the clamping arms 7 and the inner surface of the vertical portion of the L-shaped seat 18. The clamping arm 7 is kept vertical. A swing gear 13 is fixedly installed on one side of the L-shaped base 18, extending outwards from the L-shaped base 18 at the point of rotation. A rack 10 is inserted into the upper surface of the sliding base 5 at the position of each swing gear 13. Two racks 10 on the same sliding base 5 have opposite ends and mesh with adjacent swing gears 13. L-shaped racks 11 are fixedly installed at opposite ends of the two racks 10 on the same sliding base 5. The two L-shaped racks 11 are arranged in a circular array about the center of the upper surface of the sliding base 5. A steering gear 12 is rotatably connected to the center of the upper surface of the sliding seat 5, meshing with the tooth surfaces of two L-shaped racks 11. When one of the spur racks 10 moves, the connected L-shaped racks 11 move synchronously. Under the meshing action of the steering gear 12, the other L-shaped rack 11 moves at the same speed and in the opposite direction, thereby enabling the other spur rack to move at the same speed and in the opposite direction. Therefore, the two spur racks 10 on the same sliding seat 5 move at the same speed and in the opposite direction, facilitating the rotation of the two swing gears 13 on the sliding seat 5 at the same speed and in the opposite direction, thus enabling the two clamping devices on the sliding seat 5 to rotate. Arm 7 swings up or down simultaneously; one end of one of the racks 10 on each sliding seat 5 is fixedly mounted with a plate 8, and a rail 9 perpendicular to the opposite faces of the two sliding seats 5 is inserted into the plate 8. The two rails 9 are parallel and a strip 2 embedded in one side of the upper surface of the fixed seat 1 is fixedly mounted on the bottom edge of the rail 9. A hydraulic rod 3 is provided between the strip 2 and the fixed seat 1. In actual use, the extension of the hydraulic rod 3 causes the strip 2 to drive the rail 9 to move, thereby enabling the plate 8 to drive one of the racks 10 connected to it to move. In addition, in this solution, if Figure 1 As shown, the orientation of the insert strip 2 and the insert rail 9 does not affect the movement of the insert plate 8 as the sliding seat 5 moves.

[0026] A threaded rod 19 is rotatably connected to the clamping arm 7. One end of the threaded rod 19 faces the rotating end of the clamping arm 7, and a winch 14, which is inserted into the inside of the clamping arm 7, is threaded onto the threaded rod 19. The clamping arm 7 is frame-shaped, and the outer shell of the winch 14 is inserted into the inner side of the clamping arm 7. A motor 17, located inside an L-shaped seat 18 and used to drive the rotation of the threaded rod 19, is fixedly installed at one end of the clamping arm 7. A binding strap 15 is wound around the winding spool inside the winch 14, and a connecting piece 16 is fixedly installed on one side of the binding strap 15. Two connecting pieces 16 on the two sliding seats 5, located on the same side of the fixed seat 1, are connected by bolts. When the height of the clamping arm 7 in the vertical state is greater than the radius of the pipe, it can be used... The clamping arm 7 supports the side of the pipe. When the height of the vertical clamping arm 7 is lower than the radius of the pipe, the top of the clamping arm 7 can be used to support the surface of the pipe. In addition, when the clamping arm 7 is against the pipe, the position of the winch 14 is adjusted by the rotation of the threaded rod 19 driven by the motor 17 to avoid contact interference between the winch 14 and the surface of the pipe. The binding strap 15 is released by the winch 14. The connecting pieces 16 on the two binding straps 15 located at the front and rear sides of the fixing base 1 are fixed by bolts. Then, the binding strap 15 is wound up by the winch 14, so that the two connected connecting pieces 16 can press the top edge of the outer surface of the pipe, thereby pressing the pipe from above and further fixing the position of the pipe.

[0027] The method of using this utility model is as follows: When in use, the two anti-slip pads 4 on the fixed seat 1 are used to support and lift the bottom edge of the pipe. The hydraulic rod 3 extends to move the insert 2 and the insert rail 9, which in turn moves the insert plate 8 and one of the connected spur racks 10. When one spur rack 10 moves, it drives the other spur gear to move in the opposite direction at the same speed. Therefore, the two spur racks 10 on the same sliding seat 5 move in the opposite direction at the same speed, which makes it easy for the two swing gears 13 on the sliding seat 5 to rotate and swing upward at the same speed to the vertical state. Then, the two sliding seats 5 move relative to each other, and the vertical clamping arm 7 is used to clamp the surface of the pipe from the side.

[0028] The wiring diagrams of the motor 17 and hydraulic rod 3 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the motor 17 and hydraulic rod 3 will not be explained in detail.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
