Description

Technical Field

[0001] This utility model relates to the technical field of sucker rod tip cutting equipment, specifically a device for cutting off the covering material of sucker rod tip. Background Technology

[0002] The sucker rod is a slender rod in a pumping well. It connects to the polished rod at the top and the pump at the bottom to transmit power. Each sucker rod is 7.62 or 8 meters long and is generally made of low-carbon alloy steel that has undergone quenching and tempering. They are connected one by one in the tubing with internal threaded clamps and extend to the piston at the underground oil layer. They pump oil by reciprocating.

[0003] In existing sucker rod tip processing, the tip needs to be fixed before a cutter is used to cut the end covering material. However, during the cutting process, the end covering material needs to be manually held or clamped with a clamp. This clamping method has limited efficiency, and the end covering material is still prone to sticking to the sucker rod tip during the cutting process, leading to incomplete cutting or damage such as burrs. In view of this, we propose a sucker rod tip covering material removal device. Summary of the Invention

[0004] The purpose of this invention is to provide a device for cutting off the covering material of a sucker rod head, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sucker rod tip covering material cutting device, comprising a worktable, a top frame fixedly installed on the upper surface of the worktable, a hydraulic cylinder fixedly installed on the upper surface of the top frame, a plate fixedly connected to the output end of the hydraulic cylinder, a cutter fixedly installed on the lower surface of the plate, and a clamping component provided on the side of the plate;

[0006] The clamping assembly includes a hinged rod, the top end of which is hinged to the side wall of the plate. A rotating rod is fixedly installed through the top end of the hinged rod. A coil spring is sleeved on the arc-shaped outer wall of the end of the rotating rod. A clamping plate is hinged to the bottom end of the hinged rod. A contact rod is slidably installed through the bottom inner wall of the clamping plate. A spring is fixedly connected to the top end of the contact rod. A stop rod is hinged to the side wall of the contact rod. A sliding rod is hinged to the top end of the stop rod. An arc-shaped plate is movably connected to the end of the sliding rod. A trapezoidal strip is fixedly installed on the side wall of the plate.

[0007] Preferably, the number of hinge rods is provided in two sets, and the two sets of hinge rods are symmetrically arranged with the vertical central axis of the abutment plate as the axis of symmetry to ensure the balance of the force on the abutment plate. The side of the plate is provided with a hinge block to cooperate with the rotating rod to achieve hinge connection with the hinge rod.

[0008] Preferably, the bottom inner wall of the clamping plate is provided with vertical through holes on both sides of the top arc shape, so as to clamp and push the rod head of the sucker rod.

[0009] Preferably, the inner wall of the abutment plate is provided with a sliding groove that matches the sliding rod, and the sliding groove is horizontally arranged so that when the contact rod moves up relative to the abutment plate, it cooperates with the abutment rod to cause the sliding rod to drive the arc plate to move towards the center side of the abutment plate.

[0010] Preferably, the top slope of the trapezoidal strip is located below the hinge rod, thereby suppressing the tendency of the hinge rod to tilt toward the cutter side.

[0011] Preferably, the clamping plate is provided with a clamping component inside. The clamping component includes a round rod, which is inserted through and fixedly installed at one end of the slide rod near the arc-shaped plate. The inner wall of the arc-shaped plate is provided with an arc-shaped groove, and the round rod is disposed in the arc-shaped groove. An arc-shaped groove is provided on the outer wall of the arc-shaped plate near the center of the clamping plate, and the inner surface of the arc-shaped groove is provided with a raised ridge.

[0012] Preferably, the outer diameter of the round rod is adapted to the inner diameter of the arc-shaped groove, and the arc-shaped groove has a slot with a width adapted to the slide rod at one end near the slide rod, so as to avoid interference with the movement of the slide rod and the round rod.

[0013] Compared with the prior art, the present invention provides a device for cutting off the coating material of the sucker rod tip, which has the following beneficial effects:

[0014] 1. This sucker rod tip covering material cutting device, by means of a clamping component, works in conjunction with the continuous downward movement of the plate and the cutter. When the clamping plate abuts against the sucker rod tip and can no longer move downward, the thrust of the hinge rod causes the clamping plate to tilt away from the cutter by rotating around the hinge point between it and the hinge rod. At this time, the side of the arc plate and the top of the through hole push the sucker rod tip covering material outward, so that the sucker rod tip will not tilt or stick to the cutter side during the cutting operation. It can be quickly separated after cutting, which is convenient for collection and reduces the danger of manual operation.

[0015] 2. The sucker rod tip covering material cutting device is equipped with a clamping component. When the clamping plate tilts away from the cutter, the arc-shaped plate is pressed against the surface of the sucker rod tip. The rotation of the clamping plate ensures that the arc-shaped plate remains in contact with the sucker rod tip even as it rotates. The friction provided by the protruding ridges ensures the dragging effect on the cut sucker rod tip covering material, allowing it to be smoothly separated from the sucker rod.

Detailed Implementation

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: a sucker rod tip covering material cutting device, including a workbench 1, a top frame 2 fixedly installed on the upper surface of the workbench 1, a hydraulic cylinder 3 fixedly installed on the upper surface of the top frame 2, a plate 4 fixedly connected to the output end of the hydraulic cylinder 3, a cutter 5 fixedly installed on the lower surface of the plate 4, and a clamping assembly 6 provided on the side of the plate 4. The clamping assembly 6 includes a hinge rod 61, a rotating rod 62, a coil spring 63, a clamping plate 64, a contact rod 65, a spring 66, a clamping rod 67, a sliding rod 68, an arc plate 69, and a trapezoidal strip 610.

[0023] In one embodiment of this utility model, the top end of the hinge rod 61 is hinged to the side wall of the plate 4. A rotating rod 62 is fixedly installed through the top end of the hinge rod 61. A coil spring 63 is sleeved on the arc-shaped outer wall of the end of the rotating rod 62. A pressing plate 64 is hinged to the bottom end of the hinge rod 61. A contact rod 65 is slidably installed through the bottom inner wall of the pressing plate 64. A spring 66 is fixedly connected to the top end of the contact rod 65. A stop rod 67 is hinged to the side wall of the contact rod 65. A sliding rod 68 is hinged to the top end of the stop rod 67. An arc-shaped plate 69 is movably connected to the end of the sliding rod 68. A trapezoidal strip 610 is fixedly installed on the side wall of the plate 4.

[0024] Furthermore, the upper surface of the workbench 1 is equipped with multiple sets of clamps to clamp and fix the sucker rod body, ensuring relative stability during the cutting process and avoiding oblique cuts. At the same time, the plate 4 is parallel to the upper surface of the workbench 1, and the cutter 5 is vertically mounted on the workbench 1 to facilitate the cutting operation of the sucker rod body. In addition, the clamping component 6 is located on the side of the plate 4 near the sucker rod head, so that the clamping component 6 can clamp and press the sucker rod head covering area during the cutting operation to ensure the effectiveness of the cutting operation of the sucker rod head covering material.

[0025] In addition, two sets of hinge rods 61 are provided, and the two sets of hinge rods 61 are symmetrically arranged about the vertical central axis of the abutment plate 64 to ensure the balance of force on the abutment plate 64. At the same time, hinge blocks are provided on the side of the plate 4 to cooperate with the rotating rod 62 to achieve hinge connection with the hinge rods 61. Furthermore, the bottom inner wall of the abutment plate 64 has vertical through holes with an arc shape on the top and two sides to facilitate the abutment and push of the sucker rod head. At the same time, two sets of contact rods 65 are provided, and the two sets of contact rods 65 are symmetrically arranged about the vertical central axis of the abutment plate 64. Thus, when the clamping plate 64 moves downward due to the downward movement of the plate 4, the bottom end of the contact rod 65 first contacts the upper surface of the worktable 1, and then retracts within the clamping plate 64 as the clamping plate 64 continues to move downward. Specifically, the inner wall of the clamping plate 64 is provided with a groove that matches the slide rod 68, and the groove is horizontally arranged so that when the contact rod 65 moves upward relative to the clamping plate 64, it cooperates with the abutment rod 67 to cause the slide rod 68 to drive the arc plate 69 to move towards the center of the clamping plate 64, thereby clamping the sucker rod head in the middle from the side.

[0026] Meanwhile, the top slope of the trapezoidal strip 610 is set below the hinge rod 61, thereby suppressing the tendency of the hinge rod 61 to tilt toward the cutter 5, so that it can only deflect downward to a certain angle, thereby ensuring that the clamping plate 64 can move downward and eventually produce a tilting deflection away from the cutter 5, so as to achieve the effect of cutting off and removing the material covering the sucker rod head.

[0027] Specifically, the clamping plate 64 is provided with a clamping component 7 inside. The clamping component 7 includes a round rod 71, which is inserted through and fixedly installed at one end of the slide rod 68 near the arc plate 69. The inner wall of the arc plate 69 is provided with an arc-shaped groove 72, and the round rod 71 is disposed in the arc-shaped groove 72. An arc-shaped groove 73 is provided on the outer wall of the arc plate 69 near the center of the clamping plate 64, and a protruding ridge 74 is provided on the inner surface of the arc-shaped groove 73.

[0028] In this embodiment of the invention, the outer diameter of the round rod 71 is adapted to the inner diameter of the arc-shaped groove 72. At the same time, the arc-shaped groove 72 has a slot with a width adapted to the slide rod 68 at one end near the slide rod 68 to avoid interference with the movement of the slide rod 68 and the round rod 71. Specifically, the arc-shaped groove 73 allows the arc-shaped plate 69 on the side of the sucker rod head to better fit the surface of the sucker rod head covering material. The number of protrusions 74 is set in multiple sets, which are evenly distributed in the arc-shaped groove 73. When the clamping plate 64 tilts away from the cutter 5, the arc-shaped plate 69 is pressed against the surface of the sucker rod head. The rotation of the clamping plate 64 ensures that the arc-shaped groove 73 remains in contact with the sucker rod head even if the arc-shaped plate 69 rotates with it. The friction provided by the protrusions 74 ensures the dragging effect on the cut sucker rod head covering material, allowing it to be smoothly separated from the sucker rod.

[0029] In this invention, during use, the portion of the sucker rod to be removed is aligned with the cutter 5, and the entire sucker rod body is fixed to the fixture on the workbench 1. At this time, the hydraulic cylinder 3 is controlled to drive the plate 4 and cutter 5 downwards. As the plate 4 continues to move downwards, the bottom end of the contact rod 65 first contacts the upper surface of the workbench 1. Then, as the pressing plate 64 continues to move downwards, the top end of the contact rod 65 continuously retracts towards the inside of the pressing plate 64, cooperating with the abutment rod 67 to cause the sliding rod 68 to drive the arc-shaped plate 69 towards the center of the pressing plate 64. The sucker rod head is clamped from the side. As the plate 4 continues to move downward, the clamping plate 64 cannot move further downward. As a result, the clamping plate 64 tilts away from the cutter 5 with the hinge point between it and the hinge rod 61 as the center of rotation. At this time, the side of the arc plate 69 and the top of the through hole push the sucker rod head covering material outward, so that the sucker rod head will not tilt or stick to the cutter 5 during the cutting operation. It can be quickly separated after cutting, which is convenient for collection and reduces the danger of manual operation.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
