Description

Technical Field

[0001] This utility model relates to the field of anchor cable and anchorage processing technology, specifically to a clamp for turning anchor cables and anchorages. Background Technology

[0002] Anchors are devices used to fix anchor cables in rock or soil, ensuring their stability and tension. During production, anchors require machining on a lathe, necessitating the use of clamps for this process. Existing technology includes a patent (CN 219633172 U) disclosing a clamp for cutting anchor cables, comprising a shell, turntable, connecting block, main machine, and workpiece. Compared to traditional clamps, this equipment automatically and periodically opens and closes the clamping components, eliminating the need for workers to use foot pedals, saving labor, increasing overall equipment efficiency, and reducing the likelihood of misoperation or unnecessary operations. This results in higher work quality. Furthermore, the clamping components can be selected based on the specifications of the workpiece, enabling the equipment to process various sizes of workpieces. This invention improves the working range of the equipment and ensures its operational stability. Applicable to the field of anchor cutting, this device uses a bidirectional lead screw to rotate, causing two clamping blocks to come together and perform machining clamping on the anchor. However, the threaded connection between the bidirectional lead screw and the moving end lacks lubrication. Long-term use of the bidirectional lead screw will increase its wear and shorten its service life. Furthermore, the exposed bidirectional lead screw means that slag generated during later anchor machining may splash onto the threaded connection between the bidirectional lead screw and the moving end, affecting the thread transmission of the bidirectional lead screw. Therefore, we propose a clamp for anchor machining. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a clamp for turning anchor cables and anchors. This device, through components, utilizes contact extrusion force and spring force to automatically replenish lubricating oil to the lead screw transmission part of the turning clamp during the movement of the anchor cable and anchor. This lubrication reduces the wear rate of the lead screw and improves its service life. At the same time, the exposed end of the lead screw is wrapped with a bellows to prevent slag from interfering with its thread transmission. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a clamp for turning anchor cables and anchors, including a rotating seat, two transversely symmetrical dovetail grooves 1 are provided on the front side of the rotating seat, a movable seat is slidably connected inside each dovetail groove 1, a clamping seat is installed on the front side of each movable seat, a bidirectional lead screw is rotatably connected between the two dovetail grooves 1 through a bearing 1, and the left and right ends of the bidirectional lead screw are threadedly connected to the adjacent clamping seats, and a protective lubrication mechanism is also included;

[0005] The protective lubrication mechanism includes an oil reservoir, rectangular grooves, sealing seats, and opening / closing components. The oil reservoirs are located at the upper part of the interior of the movable seat. Each oil reservoir has two laterally symmetrical rectangular grooves in its lubrication port on the bottom wall. Sealing seats are slidably connected inside each rectangular groove. Opening / closing components are provided between each dovetail groove and the adjacent oil reservoir. The opening / closing components are installed in conjunction with the vertically adjacent sealing seats. This device uses contact pressure and spring force to automatically replenish the lubricating oil to the lead screw drive part of the turning fixture during the movement of the anchor clamp. This lubrication reduces the wear rate of the lead screw and improves its service life. At the same time, the exposed end of the lead screw is wrapped with a bellows to prevent slag from interfering with its thread drive.

A brake motor is provided on the outside of the rotating base. The input terminal of the brake motor is electrically connected to the output terminal of the microcontroller. The output shaft of the brake motor is fixedly connected to the left end of the bidirectional lead screw to control the clamping of the anchor cable and anchor for the anchor cable turning fixture.

[0007] Furthermore, the protective lubrication mechanism also includes a telescopic column and a spring. The telescopic column and the spring are respectively disposed between the rectangular groove and the adjacent sealing seat. The spring is movably connected to the outer end of the adjacent telescopic column. Through the compression and reset elastic force of the spring, the movement of the sealing seat in the anchor cable turning fixture is automatically reset.

[0008] Furthermore, the opening and closing assembly includes a slide rod, a fixed ring, a synchronizing ring, a second spring, a conical seat, and a rubber sealing ring. The slide rods are slidably connected to the circular holes opened in the top wall of the oil storage cavity. The top wall of the oil storage cavity is provided with a fixed ring. The middle part of the slide rod is provided with a synchronizing ring. A second spring is provided between the synchronizing ring and the vertically adjacent fixed ring.

The slide rod is installed in cooperation with the vertically adjacent conical seat and the sealing seat. The upper side of the movable seat is provided with a rubber sealing ring to control the opening and closing of the lubrication part of the screw drive in the anchor cable and anchor tool turning fixture.

[0009] Furthermore, the protective lubrication mechanism also includes bellows, which are respectively disposed between the dovetail groove and the adjacent movable seat and between the opposite inner sides of the two movable seats. The bellows are movably sleeved on the outer end of the bidirectional lead screw to wrap the exposed part of the bidirectional lead screw in the anchor cable and anchor turning fixture.

[0010] Furthermore, the protective lubrication mechanism also includes an oil plug cover, which is threaded to the outer side of the oil inlet pipe of the oil storage chamber, so as to facilitate the replenishment of lubricating oil in the oil storage chamber of the anchor cable and anchor tool turning fixture.

[0011] Furthermore, each of the movable seats has a dovetail groove II on its front side, and the rear end of each clamping seat is slidably connected to the adjacent dovetail groove II. Each of the upper rear ends of the clamping seat has two locking holes, and the upper end of each movable seat is threaded with two locking bolts. The lower ends of the locking bolts are inserted into the adjacent locking holes, which facilitates the replacement of the clamping components of the anchor cable and anchor turning fixture.

At the same time, the exposed end of the lead screw is wrapped with a bellows to prevent slag from interfering with its thread transmission. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment provides a technical solution: a clamp for machining anchor cables and anchors, including a rotary seat 1. Two transversely symmetrical dovetail grooves 3 are formed on the front side of the rotary seat 1. A movable seat 4 is slidably connected inside each dovetail groove 3. A clamping seat 5 is mounted on the front side of each movable seat 4. A bidirectional lead screw 6 is rotatably connected between the two dovetail grooves 3 via a bearing. Both ends of the bidirectional lead screw 6 are threadedly connected to the adjacent clamping seat 5. The device also includes a microcontroller 2, located outside the rotary seat 1. The input end of the microcontroller 2 is electrically connected to an external power supply. The outer side of the rotary seat 1 is provided with… A brake motor 8 is provided, with its input terminal electrically connected to the output terminal of the microcontroller 2. The output shaft of the brake motor 8 is fixedly connected to the left end of the bidirectional lead screw 6. Each movable seat 4 has a dovetail groove 9 on its front side, and the rear end of each clamping seat 5 is slidably connected to an adjacent dovetail groove 9. Each clamping seat 5 has two locking holes 10 on its upper rear end, and two locking bolts 11 are threaded onto the upper end of each movable seat 4. The lower ends of the locking bolts 11 are inserted into adjacent locking holes 10. When machining and clamping the anchor cable, the anchor cable is first placed between the two clamping seats 5. Subsequently, the microcontroller 2 starts the brake motor 8, causing its output shaft to drive the bidirectional lead screw 6 to rotate forward. (A slip ring is installed between the output end of the microcontroller 2 and the input end of the brake motor 8. The slip ring consists of a conductive slip ring and a connecting contact point. The conductive slip ring is fixedly sleeved on the rotating shaft of the external drive anchor cable turning fixture. The connecting contact point is laid on the external lathe rotating shaft mounting part. The slip ring prevents the brake motor 8 from winding during the turning rotation of the anchor cable turning fixture.) The bidirectional lead screw 6 is connected by a thread, causing the moving seat 4 to move along the dovetail groove 3. The two clamping seats 5 move closer to each other to squeeze and clamp the anchor cable. When the clamping seats 5 are worn, the locking bolt 11 is rotated to move it vertically upward through the threaded connection with the corresponding moving seat 4, so that the lower end of the locking bolt 11 moves out of the corresponding locking hole 10, thereby releasing the sliding limit of the clamping seat 5 along the dovetail groove 9. Then the clamping seat 5 is taken out from the dovetail groove 9 for replacement, and the replaced clamping seat 5 is reinstalled on the moving seat 4 using the same principle. The replacement operation of the clamping seat 5 is convenient, and it also includes a protective lubrication mechanism 7.

[0021] The protective lubrication mechanism 7 includes an oil reservoir 71, rectangular grooves 72, sealing seats 75, and opening / closing components 76. The oil reservoirs 71 are located at the upper interior of the movable seat 4. Each oil reservoir 71 has two laterally symmetrically distributed rectangular grooves 72 within its lubrication port on the bottom wall. Sealing seats 75 are slidably connected inside each rectangular groove 72. Opening / closing components 76 are provided between the dovetail groove 3 and adjacent oil reservoirs 71, and each opening / closing component 76 is installed in conjunction with a vertically adjacent sealing seat 75. The protective lubrication mechanism 7 also includes a telescopic column 73 and a spring 74, which are respectively located between the rectangular grooves 72 and adjacent sealing seats 75. Each spring 74 is movably sleeved with the outer end of the adjacent telescopic column 73. The opening / closing components 76 include... The lubrication mechanism 7 includes a slide rod 761, a fixed ring 762, a synchronizing ring 763, a second spring 764, a conical seat 765, and a rubber sealing ring 766. The slide rod 761 is slidably connected to a circular hole in the top wall of the oil reservoir 71. Each oil reservoir 71 has a fixed ring 762 on its top wall. Each slide rod 761 has a synchronizing ring 763 in its middle section. A second spring 764 is installed between the synchronizing ring 763 and the vertically adjacent fixed ring 762. The second spring 764 is movably sleeved with the outer side of the adjacent slide rod 761. Each dovetail groove 3 has a conical seat 765 at its top. Each slide rod 761 is fitted with the vertically adjacent conical seat 765 and the sealing seat 75. The upper side of the movable seat 4 has a rubber sealing ring 766. The protective lubrication mechanism 7 also includes a bellows 77. The bellows 77 are respectively located between the dovetail groove 3 and the adjacent movable seat 4, and between the opposite inner surfaces of the two movable seats 4. All bellows 77 are movably sleeved on the outer end of the double-acting screw 6. The protective lubrication mechanism 7 also includes an oil plug cover 78, which is threaded to the outer surface of the oil inlet pipe of the oil reservoir 71. During the movement of the movable seat 4 along the outer side of the double-acting screw 6, the bellows 77 wrap around the exposed parts of the double-acting screw 6 (the bellows 77 is a corrugated structure made of multiple layers of metal sheets, its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance), preventing subsequent machining residue from the anchor cable and anchorage from entering the transmission gap of the double-acting screw 6, thus hindering the threaded transmission of the double-acting screw 6. As the movable seat 4 moves along the dovetail groove 3, when it passes the corresponding conical seat 765, the upper end of the slide rod 761 presses against the conical surface of the corresponding conical seat 765. The slide rod 761, under pressure, causes the corresponding synchronous ring 763 to move vertically downwards, and the second spring 764 continues to stretch (initially in a stretched state). The lower end of the slide rod 761 presses against the inclined surface on the upper side of the corresponding sealing seat 75. The sealing seats 75, under pressure, slide into the corresponding rectangular grooves 72. The telescopic end of the telescopic column 73 and the first spring 74 retract, thereby separating the two adjacent sealing seats 75, releasing the blockage of the lubrication port of the oil storage chamber 71, allowing the lubricating oil in the oil storage chamber 71 to flow out through the lubrication port and self-lubricate the outer side of the bidirectional lead screw 6.To reduce wear and tear on the bidirectional lead screw 6 and extend its service life, when the upper end of the slide rod 761 contacts and separates from the corresponding tapered seat 765, the tension and reset force of the second spring 764 causes the synchronizing ring 763 to move the slide rod 761 upwards to reset. The contraction and reset force of the first spring 74 causes the two adjacent sealing seats 75 to come together and press against each other, sealing the lubrication port in the oil reservoir 71 again. The rubber sealing ring 766 uses its own elasticity and plasticity to seal the sliding gap between the slide rod 761 and the corresponding circular hole. To prevent lubricating oil from overflowing through the gap, the oil plug cap 78 is rotated to remove it from the oil inlet pipe of the oil reservoir 71. Lubricating oil can then be replenished into the oil reservoir 71 through the oil inlet pipe. This device, through its components, utilizes contact pressure and spring force to automatically replenish lubricating oil to the lead screw drive part of the turning fixture during movement of the anchor cable clamp. This lubrication reduces the wear rate of the lead screw and extends its service life. Simultaneously, the exposed end of the lead screw is wrapped with a bellows to prevent slag from interfering with its thread drive.

[0022] The working principle of the anchor cable anchor turning fixture provided by this utility model is as follows: When turning and clamping the anchor cable anchor, first place the anchor cable anchor between two clamping seats 5. Then, the microcontroller 2 starts the brake motor 8, causing its output shaft to drive the bidirectional lead screw 6 to rotate forward (a slip ring is installed between the output end of the microcontroller 2 and the input end of the brake motor 8. The slip ring is divided into a conductive slip ring and a connecting contact point. The conductive slip ring is fixedly sleeved on the external rotating shaft that drives the anchor cable anchor turning fixture to rotate as a whole. The connecting contact point is laid on the external rotating shaft mounting part of the lathe. The slip ring avoids the brake motor 8 from winding during the turning rotation of the anchor cable anchor turning fixture). The bidirectional lead screw 6 is connected by a thread, causing the moving seat 4 to move along the yoke. The tail groove 3 drives the two clamping seats 5 to move closer together, thereby squeezing and clamping the anchor cable and anchorage. As the moving seat 4 moves along the outside of the bidirectional screw 6, it wraps the exposed parts of the bidirectional screw 6 through the bellows 77 (the bellows 77 is a corrugated structure made of multiple layers of metal sheets, its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance), preventing subsequent machining residue from the anchor cable and anchorage from entering the transmission gap of the bidirectional screw 6, thus hindering the thread transmission of the bidirectional screw 6. As the moving seat 4 moves along the dovetail groove 3, when the moving seat 4 passes the corresponding conical seat 765, the upper end of the slide rod 761 makes contact with the conical surface of the corresponding conical seat 765. When 761 is pressed, the corresponding synchronous ring 763 moves vertically downward, and spring 764 continues to stretch (spring 764 is initially in a stretched state). The lower end of the slide rod 761 presses against the inclined surface on the upper side of the corresponding sealing seat 75. The sealing seats 75 slide into the corresponding rectangular grooves 72 under pressure. The telescopic end of the telescopic column 73 and spring 74 retract, thereby separating the two adjacent sealing seats 75 from each other, releasing the blockage of the lubrication port of the oil storage chamber 71, allowing the lubricating oil in the oil storage chamber 71 to flow out through the lubrication port and self-lubricate the outside of the double-acting screw 6, reducing the wear of the double-acting screw 6 and improving its service life. When the upper end of the slide rod 761 contacts and separates from the corresponding conical seat 765, the tension and restoring force of spring 764... The synchronizing ring 763 causes the slide rod 761 to move upward and reset. The retraction and reset force of the spring 74 causes the two adjacent sealing seats 75 to come together and press against each other, sealing the lubrication port in the oil reservoir 71 again. The rubber sealing ring 766, using its elasticity and plasticity, seals the sliding gap between the slide rod 761 and the corresponding circular hole, preventing lubricating oil from leaking out. When the clamping seat 5 is severely worn, the locking bolt 11 is rotated to move it vertically upward through the threaded connection with the corresponding moving seat 4, causing the lower end of the locking bolt 11 to move out of the corresponding locking hole 10, thereby releasing the sliding limit of the clamping seat 5 along the dovetail groove 9. The clamping seat 5 is then removed from the dovetail groove 9 for replacement.The replaced clamping seat 5 is then reinstalled onto the movable seat 4 using the same principle. The clamping seat 5 is easy to replace; simply rotate the oil plug cover 78 to remove it from the oil inlet pipe of the oil reservoir 71. Lubricating oil can then be replenished into the oil reservoir 71 through the oil inlet pipe.

[0023] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be NY8A050D, the brake motor 8 can be HDWZ1-50, and the microcontroller 2 controls the operation of the brake motor 8 using methods commonly used in the prior art.
