Description

Technical Field

[0001] The utility model relates to the technical field of thread rolling machines, and in particular to a high-speed thread rolling machine for nut production. Background Art

[0002] A thread rolling machine is a device that uses two rolling wheels to roll out threads on a bolt blank. The main working principle of the thread rolling machine is that the nut to be processed is placed in the thread rolling station. Under the driving force of the driving device, the wire wheel squeezes the nut to form threads or wire mesh patterns on the nut. The existing high-speed thread rolling machine for nut production usually requires the staff to manually grasp the nut and place the bolt in the middle position of the thread rolling machine for processing. After a period of processing, the bolt needs to be manually pushed in again and cannot be kept in the thread rolling position all the time, which reduces the continuity and efficiency of the processing and causes the risk of the nut popping out, making the operation process too cumbersome and the production efficiency low. Therefore, improvement and optimization are needed. Utility Model Content

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1, as Figures 1 to 5 As shown, a high-speed thread rolling machine for nut production includes a chassis 1, a bottom plate 2 is fixedly installed on the top of the chassis 1, a bracket 3 is fixedly installed on the top of the bottom plate 2, a ring block 4 is rotatably installed on the front of the bracket 3, and the ring block 4 passes through the bracket 3 so that the front of the bracket 3 is hollow, a support block 6 is fixedly installed on the front of the ring block 4, a ring block 2 7 is fixedly installed on the top of the support block 6, an ear block 5 is fixedly installed on the upper outer surface of the ring block 4, a convex block 8 is fixedly installed on the top of the ear block 5, and a ring block 4 is fixedly installed on the front of the bracket 3. Bump 2 9, bump 1 8 and bump 2 9 are internally threaded with a screw 10, and both ends of the screw 10 pass through the inside of bump 1 8 and bump 2 9. A rotating block 11 is fixedly installed on the outer surface of the top right side of the screw 10. A hollow sleeve block 12 is fixedly installed between the annular block 1 4 and the annular block 2 7. A telescopic long block 13 is fixedly sleeved inside the hollow sleeve block 12, and the telescopic long block 13 extends to the inside of the annular block 2 7. A rotating rod 15 is rotatably installed on the top of the bracket 3, and the rotating rod 15 is fixedly connected to the telescopic long block 13. A roller 14 is rotatably installed on the inside of the right end of the telescopic long block 13.

[0026] When the staff rotates the rotating block 11, the protrusion 18 will be displaced. When the protrusion 18 is displaced, the ear block 5 will be displaced. When the ear block 5 is displaced, the annular block 4 will be rotated. When the annular block 4 is rotated, the support block 6 will drive the annular block 2 7 to start rotating. When the annular block 2 7 is rotated, the three hollow sleeve blocks 12 will be retracted inward against the three telescopic long blocks 13. When the telescopic long block 13 is tightened inward, the rotating rod 15 will be driven to rotate. When the telescopic long block 13 is tightened inward, the roller 14 will be driven to gradually fit the nut to achieve fixed clamping.

[0027] By rotating the rotating block 11, the protrusion 18 and the ear block 5 start to move. When the ear block 5 starts to move, the annular block 14, the support block 6 and the annular block 2 7 start to rotate. When the annular block 2 7 rotates, the hollow sleeve block 12 will retract inward against the telescopic long block 13. When the telescopic long block 13 is tightened inward, the rotating rod 15 will be driven to rotate. Compared with the traditional device, the present device keeps the nut positioned in the middle position of the thread rolling mechanism, avoiding processing interruption or repeated processing due to nut shaking or displacement, thereby improving the continuity and efficiency of the processing, effectively preventing the nut from popping out, ensuring the safety of the operator, and reducing the time of manual adjustment of the nut position.

[0028] In embodiment 2, a slide groove 16 is provided on the top of the chassis 1, and the slide groove 16 is divided into two groups, each group of two being provided on the left and right sides of the top of the chassis 1 respectively. A C-shaped bracket 17 is slidably installed on the inner side of the slide groove 16, and the two C-shaped brackets 17 are slidably installed on the inner side of the slide groove 16. The internal thread of the C-shaped bracket 17 is sleeved with a forward and reverse screw rod 19, and both ends of the forward and reverse screw rod 19 pass through the interior of the C-shaped bracket 17.

A fixed block 18 is fixedly installed on the top of the C-shaped bracket 17, and a thread rolling mechanism is fixedly installed on the inner side of the fixed block 18.

[0029] When the staff rotates the rotating block 20, when the rotating block 20 rotates the forward and reverse screw rods 19, it will drive the C-shaped bracket 17 to slide on the inner side of the slide groove 16. When the two C-shaped brackets 17 shrink inward, the top fixed block 18 will also shrink inward. When the fixed block 18 begins to shrink inward, it will drive the thread rolling mechanism to shrink inward as well, so that the distance can be accurately controlled.

[0030] By rotating the rotating block 20, when the rotating block 20 rotates the forward and reverse screw rods 19, the C-shaped bracket 17 will be driven to slide on the inner side of the slide groove 16. When the two C-shaped brackets 17 shrink inward, the top fixed block 18 and the thread rolling mechanism will also shrink inward. Compared with the traditional device, this device avoids problems such as loose connection or inability to assemble due to inaccurate thread rolling distance. The best processing effect can be ensured by adjusting the distance. There is no need to equip different thread rolling mechanisms for nuts of different specifications, which greatly improves the versatility of the equipment, ensures the consistency of the processing accuracy of each nut, and improves the overall quality of the product.

[0031] The thread rolling mechanism of embodiment 3 includes a fixed block 18 on the inner side of which a bracket three 32 is fixedly installed, a thread rolling wheel 23 is rotatably installed on the inner side of the bracket three 32, a bracket two 21 is fixedly installed on the front side of the inner bracket three 32 of the fixed block 18, a motor 22 is fixedly installed on the inner side of the bracket two 21 and the output shaft of the motor 22 extends to the inside of the bracket three 32 and is fixedly connected to the thread rolling wheel 23.

[0032] By starting the motor 22, the thread rolling wheels 23 will start to rotate, and then the thread rolling effect is achieved by the relative rotation of the two thread rolling wheels 23.

[0033] In embodiment 4, a second slide groove 25 is provided between the two groups of first slide grooves 16 on the top of the chassis 1 , and there are two second slide grooves 25 between the two groups of first slide grooves 16 , and a collecting mechanism is slidably installed inside the second slide groove 25 .

[0034] Through the design of the two second slide grooves 25, the smooth surface inside the slide groove 25 will make the sliding smooth, thereby facilitating the collection mechanism to be pulled outward.

[0035] The collecting mechanism of embodiment 5 includes a slide block 26 slidably mounted on the inner side of the second slide groove 25 , a collecting groove 27 fixedly mounted on the top of the slide block 26 , and a pulling rod 28 fixedly mounted on the outer surface of the collecting groove 27 .

[0036] By pulling the pull rod 28 outward, the slider 26 at the bottom of the collecting trough 27 slides outward along the second slide groove 25, thereby facilitating the collection of the collected waste.

[0037] In Example 6, an arc-shaped cover 24 is fixedly installed on the inner side of the fixed block 18, and the arc-shaped cover 24 is arc-shaped and directly above the thread rolling mechanism.

[0041] In Example 8, a cross groove is provided on the upper right side of the top of the chassis 1. A cross protrusion 29 is movably sleeved in the cross groove and the outer surface of the cross protrusion 29 is smooth. A tool box 30 is fixedly installed on the top of the cross protrusion 29.

[0042] The cross protrusion 29 is driven to be taken out along the cross groove by the tool box 30, so that the staff can avoid using various tools and avoid malfunctions caused by untimely use of tools.

[0043] In Example 9, the C-shaped bracket 17 is slidably mounted in the slide groove 16 in a C-shape, and the outer surface of the C-shaped bracket 17 is smooth.

[0044] The C-shaped bracket 17 has a smooth design, so that it can slide smoothly inside the slide groove 16 to avoid jamming.

[0045] In embodiment 10, a base 31 is fixedly installed on the top of the chassis 1, and the base 31 is fixedly installed on the four sides of the chassis 1.

[0046] The base 31 is present around the bottom of the chassis 1, so that the entire device is more stable and the operation of the device is prevented from being affected by external forces.

[0048] When the staff rotates the rotating block 11, the protrusion 18 will be displaced. When the protrusion 18 is displaced, the ear block 5 will be displaced. When the ear block 5 is displaced, the annular block 4 will be rotated. When the annular block 4 is rotated, the support block 6 will drive the annular block 2 7 to start rotating. When the annular block 2 7 is rotated, the three hollow sleeve blocks 12 will be retracted inward against the three telescopic long blocks 13. When the telescopic long block 13 is tightened inward, the rotating rod 15 will be driven to rotate. When the telescopic long block 13 is tightened inward, the roller 14 will be driven to gradually fit the nut to achieve fixed clamping.

[0049] When the staff rotates the rotating block 20, when the rotating block 20 rotates the forward and reverse screw rods 19, it will drive the C-shaped bracket 17 to slide on the inner side of the slide groove 16. When the two C-shaped brackets 17 shrink inward, the top fixed block 18 will also shrink inward. When the fixed block 18 begins to shrink inward, it will drive the thread rolling mechanism to shrink inward as well, so that the distance can be accurately controlled.
