Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a large-scale automatic thread rolling device for anchor screws. Background Art

[0002] Anchor bolts are screw rods used to fasten equipment to concrete foundations. They are generally used in infrastructure such as railways, highways, power companies, factories, mines, bridges, tower cranes, large-span steel structures and large buildings. They have strong stability;

[0003] After the steel is cut into rods, the rods are threaded by an automatic three-axis thread rolling machine for use in foundation construction. The three-axis thread rolling machine has three equally triangularly supported thread rolling wheels, which are divided into a main thread rolling wheel, an auxiliary thread rolling wheel and a positioning thread rolling wheel. When rolling the thread, an automatic thread rolling effect is achieved;

[0004] In order to adapt to the thread rolling of rods with various outer diameters, the automatic thread rolling machines on the market can move one or two of the rolling wheels. However, there is no synchronous advance and retreat function of the three-axis thread rolling wheels. The separate transmission of the thread rolling wheels will make it difficult to fully synchronize the angular velocities of the three rolling wheels. The quality of the threads rolled out of the rod is poor, and the installation is difficult. In addition, the thread rolling wheels are wearing parts and must be maintained or replaced regularly. During this period, if a staff member makes an error in operation or an electrical failure occurs, the drive motor that drives the thread rolling wheel to rotate will start, causing the thread rolling wheel to rotate, posing a safety hazard. For this reason, it is necessary to propose a large-scale anchor screw automatic thread rolling equipment with high safety. Summary of the invention

The slider 62 is in the shape of an I-beam, which improves the stability of the slider 62 on the casing 61. A plurality of tooth grooves 63 are equidistantly provided on the left side wall of the slider 62 from the inside to the outside. A first rotating shaft 64 capable of rotating around its own axis is installed in the slider 62 through a bearing. The right end of the first rotating shaft 64 is installed with the left end of the universal shaft 10, and a detachable thread rolling wheel 65 is installed on the left end of the first rotating shaft 64. The three thread rolling wheels 65 perform tasks respectively. The main thread rolling wheel is responsible for the main rolling work. It rolls the workpiece through rotation and feeding.

[0031] As a preferred solution, further, the brake assembly 95 includes a sleeve 951 that is laterally fixedly connected to the bottom end of the right side wall of the gear box 91, a slide groove 952 is opened on the right side of the upper surface of the sleeve 951, and positioning grooves 953 are opened on both sides of the inner cavity of the slide groove 952. An inner rod 954 that can slide left and right is inserted into the inner cavity of the sleeve 951, and a vertical rod 955 is vertically installed at the right end of the upper surface of the inner rod 954. The width of the vertical rod 955 is smaller than the width of the inner cavity of the slide groove 952 to ensure that the vertical rod 955 can shuttle between the slide groove 952 and the positioning groove 953. The outer wall of the vertical rod 955 is sleeved with a The handle 956 slides up and down, and when the handle 956 is inserted into the inner cavity of the positioning groove 953, the inner rod 954 is positioned. A mounting plate 957 is installed at the left end of the inner rod 954 along the front-to-back direction. Brake rods 958 are installed at the front and rear ends of the left side wall of the mounting plate 957. The left end of the brake rod 958 is conical in shape, and the distance between the two brake rods 958 is larger than the outer diameter of the blocking rod 94. When the brake rod 958 moves to the left, it is affected by the curved surface of the blocking rod 94, and the brake rod 958 can push the blocking rod 94, so that the blocking rod 94 is located between the two brake rods 958, thereby preventing the brake rod 958 from rotating.

[0032] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0033] Step 1: Aim the nozzle of the cooling device at the thread rolling wheel 65, spray the coolant on the thread rolling wheel 65, cool down the thread rolling wheel 65 when rolling, and put the rod horizontally between the thread rolling wheels 65 under the limiting action of the limiting rod 66, drive the second gear 93 to rotate clockwise through the second motor 92, and drive the first rotating shaft 64 to rotate under the transmission of the second gear 93 and the third gear 97, so that the thread rolling wheel 65 rolls the rod and makes it rotate from left to right to realize the automatic thread rolling of the rod. After the thread rolling is completed, drive the second gear 93 to rotate counterclockwise through the second motor 92, and then make the thread rolling wheel 65 rotate in the opposite direction, so that the rod moves to the left and exits, realizing the automatic thread rolling of the rod, and obtaining the anchor screw, and the generated iron filings fall into the receiving trough 4;

[0034] Step 2: When it is necessary to roll the thread of rods with different outer diameters, the first motor 610 drives the first gear 611 to rotate, and the turntable 67 rotates clockwise or counterclockwise under the transmission condition that the first gear 611 is meshed with the outer gear ring 69, and the steel belt 68 is inclined to squeeze the tooth groove 63 inward or outward, so that the slider 62 drives the thread rolling wheel 65 to move inward or outward, and the universal shaft 10 pulls the gear box 91 to the right or left, and the slide seat 8 moves to the right or left under the limit of the slide rail 7, and the spacing between the thread rolling wheels 65 becomes smaller or larger, and the thread rolling outer diameter becomes smaller or larger, so that the thread rolling of rods with different outer diameters can be carried out;

[0035] Step three, when the thread rolling wheel 65 needs to be maintained or replaced, lift up the handle 956 to move the handle 956 out of the positioning groove 953, release the positioning of the inner rod 954, push the inner rod 954 to the left, insert the two brake rods 958 between the blocking rods 94, lower the handle 956, insert the handle 956 into the left positioning groove 953, position the inner rod 954, and use the brake rod 958 to prevent the blocking rod 94 from rotating, thereby preventing the thread rolling wheel from rotating, thereby improving the safety when maintaining or replacing the thread rolling wheel 65.
