Technical Field

[0001] This utility model relates to the field of thread rolling machine equipment, and in particular to an adjustment device for a hollow anchor bolt thread rolling machine. Background Technology

[0002] Thread rolling is a cold extrusion forming equipment. Thread rolling machines usually have three thread rolling shafts. Within their rolling pressure range, they can perform thread rolling, straight thread rolling, and oblique thread rolling on workpieces in a cold state. They can process a variety of different specifications and types of threads and are widely used in the machinery manufacturing industry.

[0003] In existing technologies, three-axis anchor bolt thread rolling machines are often used when processing hollow anchor bolt threads. Typically, the thread rolling shaft is mounted on the machine frame and driven to rotate via a transmission shaft to roll the threads of the anchor bolts between the thread rolling shafts. However, in the use of existing technologies, it has been found that adjusting the thread rolling shaft requires workers to reach into the gap between the thread rolling shaft and the thread to adjust the thread position by manipulating the thread nut. The adjustment process is cumbersome, difficult, and requires a high level of experience from the workers. Furthermore, adjusting the thread nut can easily damage it, and the replacement process is quite troublesome.

[0004] Based on the above-mentioned technical problems, this utility model proposes an adjustment device for a hollow anchor bolt thread rolling machine. Utility Model Content

[0017] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] 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 scope of protection of the present utility model.

[0019] Example 1 like Figure 1-3 As shown, an adjustment device for a hollow anchor bolt thread rolling machine includes a frame 1. Three mounting brackets 6 are fixedly installed on the frame 1. The mounting brackets 6 are evenly distributed around the circumference of the machining center. Mounting plates 5 are installed on the mounting brackets 6. Thread rolling shafts 2 are installed on the mounting plates 5. The thread rolling shafts 2 are smooth at both ends and have thread rolling in the middle. Two pressure rods 32 are installed symmetrically along the center of the thread rolling shafts below the thread rolling shafts 2, and are in direct contact with the thread rolling shafts. The pressure rods 32 are rotatably connected to a sliding plate 51. In use, two of the thread rolling shafts are usually fixed, while the remaining thread rolling shaft moves along the direction of the machining center. The anchor bolt to be processed is placed at the machining center, and the thread rolling shaft 2 is driven to move towards the center to compress the anchor bolt. An external drive rod connected to a drive shaft 21 drives the thread rolling shaft 2 to rotate and perform rolling processing on the surface of the anchor bolt.

[0020] Mounting plate 5 has a groove on its surface, in which sliding plate 51 is slidably mounted. Sliding plate 51 is fixed to thread rolling shaft 2 via bearing seat 22. Bearing 23 is installed between bearing seat 22 and thread rolling shaft 2. The front end of mounting plate 5 is fixedly connected to adjusting plate 3 via fixing bolt 31. Adjusting plate 3 is interference-fitted to telescopic structure 33 via bearing 331. Bearing 331 is a pressure bearing. Telescopic structure 33 is a rotary telescopic structure such as a set screw. The extended end top shell 332 of telescopic structure 33 is fixedly connected to sliding plate 51. By driving the rotating handle 4 to rotate, the extended end of telescopic structure 33 can drive sliding plate 51 to move. When adjusting the thread, one thread rolling shaft is usually used as a reference, and the other two thread rolling shafts are adjusted in turn. By rotating the rotating handle, the telescopic structure is driven to push the sliding plate forward. The sliding plate carries the thread rolling shaft above and moves back and forth, which facilitates quick adjustment of the position of the thread rolling shaft.

[0021] like Figure 4 As shown, an adjusting shaft 7 is installed inside the mounting bracket 6 via bearings. A mounting plate 5 is welded to the upper end of the adjusting shaft. An adjusting gear 71 is welded to the adjusting shaft 7. A rack 8 meshes with the adjusting gear 71 at a corresponding position. The rack 8 is installed in the slide groove of the mounting bracket 6. The rack 8 is fixedly connected to the telescopic structure 2 81. The telescopic structure 2 is the same as the telescopic structure 1. Through the telescopic structure 2 81, the rack 8 is driven to move back and forth. The rack 8 drives the gear 71 to rotate. The gear 71 drives the adjusting shaft 7 to rotate. By rotating and driving the telescopic structure 81, the angle of the thread rolling shaft can be quickly adjusted.

[0022] Example 2 like Figure 5-7 As shown, a hollow anchor bolt thread rolling machine adjustment device differs from Embodiment 1 in that Embodiment 1 can quickly adjust the thread rolling shaft, but when adjusting the position of the thread rolling shaft, the operator cannot know the actual displacement of the thread rolling shaft adjustment; therefore, a clicker 91 is installed on each adjustment plate, and when adjusting the position of the thread rolling shaft, the clicker can move the thread rolling shaft to produce a clear sound.

[0023] like Figure 5 and Figure 6 As shown, when the thread rolling machine is working normally, the rattle 91 rests on the surface of the next thread rolling shaft in the clockwise direction, and is located outside the thread rolling part of the thread rolling shaft 2 in the horizontal direction. The rattle 91 is a thin, long strip of elastic sheet made of stainless steel, which can extend between two threads. The rattle 91 is fixedly connected to the positioning rod 9, and the positioning rod is rotatably connected to the top rod 42 through the top rod bearing 43. The top rod bearing is a pressure bearing, and the top rod 42 is an elastic telescopic rod installed in the blind hole of the sliding plate 51. The bottom wall of the blind hole corresponds to the center position of the thread rolling part in the horizontal direction. In the initial state, the positioning rod is outside the thread rolling part. When it is necessary to adjust the thread rolling shaft, first push the rotating handle forward. 4. The top rod 42 presses the positioning rod 9 against the bottom wall of the blind hole, and at the same time the length of the top rod 42 is compressed. At this time, the positioning rod is in the thread rolling part of the thread rolling shaft 2. Then, the rotating handle 4 is rotated, and the drive block 41 drives the telescopic structure to rotate. The front end of the telescopic structure 33 drives the sliding plate to move. During the adjustment of the position of the thread rolling shaft, since the positioning rod 9 is always pressed against the bottom of the blind hole of the sliding plate 51 by the elastic top rod 42, when the sliding plate 51 moves, it will drive the positioning rod and the clicker 91 installed on the positioning rod to move at the same time. The clicker 91 moves the thread rolling part and can make a clear sound. When the operator adjusts the position of the thread rolling shaft, he can clearly feel the amount of displacement.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
