Description

Technical Field

[0001] This utility model belongs to the field of nut tapping technology, and specifically relates to a fixing mechanism for nut tapping. Background Technology

[0002] A nut tapping retaining mechanism is a device specifically designed to stably clamp and hold a nut during tapping (i.e., cutting internal threads). This mechanism ensures that the nut remains stationary throughout the machining process, thereby guaranteeing the quality and accuracy of the tapping.

[0003] Existing nut tapping fixing mechanisms use multiple opposing fixing plates to clamp and fix the nut for subsequent tapping steps. To ensure stable tapping, all six sides of the nut usually need to be fully fixed. However, the fixed size of the clamping plates means that they can only clamp and fix nuts of a specific size. If nuts of different sizes need to be clamped and fixed, operators need to use external tools to remove multiple screws to disassemble the fixing plates and replace them with clamping plates of the corresponding size. This complicated operation is not only time-consuming and labor-intensive, but also increases labor costs and workload. Moreover, the process of replacing the clamping plates is cumbersome, resulting in low production efficiency for nut tapping. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a fixing mechanism for tapping nuts, which allows for quick disassembly and replacement of the fixing plate with a fixing plate that is compatible with the nut, significantly reducing replacement time and thus improving the production efficiency of tapping nuts.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a fixing mechanism for tapping nuts, including a placement plate, two sliding plates are slidably arranged inside the placement plate, the left and right positions of the two sliding plates are corresponding, a mounting shell is respectively provided on the inner side of the two sliding plates, a locking post is slidably arranged inside the two mounting shells, a clamping plate is slidably arranged inside the two mounting shells, a locking hole for inserting into the locking post is opened inside the two clamping plates, a locking drive unit is provided at the upper end of the locking post, the locking drive unit includes a pull plate respectively arranged at the upper end of the two locking posts, a spring is respectively arranged between the pull plate and the mounting shell, and multiple springs are respectively sleeved on the outer arc surface of the corresponding locking post.

[0006] As a further improvement of this utility model, a pusher is slidably arranged in the sliding opening inside the placement plate, a connecting plate is arranged between the two placement plates, an electric push rod is arranged at the upper end of the connecting plate, and the telescopic end of the electric push rod is connected to the lower end of the pusher.

[0007] As a further improvement of this utility model, the lower end of the placement plate is provided with two mounting plates corresponding to the left and right positions. A lead screw is rotatably provided on the inner side of each of the two mounting plates. The left and right threads of the two lead screws are opposite. The two sliding plates are respectively threadedly connected to the adjacent lead screws. The lower end of the placement plate is provided with a drive unit for driving the lead screws to rotate. The drive unit includes a dual-axis motor located at the lower end of the placement plate. The output shafts on the left and right sides of the dual-axis motor are respectively connected to the inner ends of the adjacent lead screws through couplings.

[0008] As a further improvement of this utility model, a control panel is provided at the upper end of the placement plate, and the dual-axis motor and electric push rod are electrically connected to the control panel.

[0009] As a further improvement of this utility model, the mounting plate has multiple mounting holes inside.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, by pulling the pull plates on both sides, the locking pin is disengaged from the locking hole on the clamping plate. Then, the clamping plate can be slid out from the mounting housing. At this time, the spring is in a stretched state. Next, the clamping plate that matches the nut is slid into the mounting housing. Then, the pull plates are released, and the spring quickly rebounds, causing the locking pin to be inserted into the locking hole on the new clamping plate. This allows for quick replacement of the clamping plate and rapid disassembly and replacement of the fixing plate with a fixing plate that matches the nut. This significantly reduces replacement time and improves the production efficiency of nut tapping.

[0012] Secondly, the electric push rod can be opened via the control panel. The telescopic end can drive the push frame to move upward, which can push the tapped nut to the upper end of the two clamping plates, making it easier for personnel to remove the nut and further improving production efficiency.

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown, a fixing mechanism for tapping nuts includes a placement plate 101. Two sliding plates 105 are slidably disposed inside the placement plate 101. Mounting shells 109 are respectively provided on the inner surfaces of the two sliding plates 105. Locking pins 202 are slidably disposed inside each of the two mounting shells 109. Clamping plates 106 are slidably disposed inside each of the two mounting shells 109. Locking holes for insertion into the locking pins 202 are provided inside the clamping plates 106. A locking drive unit is provided at the upper end of each locking pin 202. Two left and right positioning points are provided at the lower end of the placement plate 101. The mounting plate 102 and the placement plate 101 are fixed together by welding. A lead screw 107 is rotatably provided on the inner side of each of the two mounting plates 102. The left and right threads of the two lead screws 107 are opposite. Two sliding plates 105 are threadedly connected to the adjacent lead screws 107 respectively. A drive unit for driving the lead screws 107 to rotate is provided at the lower end of the placement plate 101. The drive unit includes a dual-axis motor 108 provided at the lower end of the placement plate 101. The output shafts on the left and right sides of the dual-axis motor 108 are respectively connected to the inner ends of the adjacent lead screws 107 through couplings.

[0021] like Figure 3 As shown, the locking drive unit includes pull plates 201 respectively disposed on the upper ends of two locking pins 202. Springs 203 are respectively disposed between the pull plates 201 and the mounting shell 109, and multiple springs 203 are respectively sleeved on the outer arc surface of the corresponding locking pins 202.

[0022] like Figure 2 , 4As shown, a pusher 303 is slidably disposed in a sliding opening inside the placement plate 101. A connecting plate 301 is disposed between the two placement plates 101. An electric push rod 302 is disposed at the upper end of the connecting plate 301. The telescopic end of the electric push rod 302 is connected to the lower end of the pusher 303.

[0023] like Figure 1 As shown, a control panel 104 is provided at the upper end of the placement plate 101, and the dual-axis motor 108 and the electric push rod 302 are both electrically connected to the control panel 104.

[0024] By placing the nut to be tapped on the placement plate 101, positioning it between the two clamping plates 106, and then controlling the dual-axis motor 108 to run via the control panel 104, the output shaft drives the lead screws 107 on both sides to rotate. Since the thread directions of the lead screws 107 on both sides are opposite, they drive the mounting shells 109 on the sliding plates 105 on both sides and the clamping plates 106 inside to move closer together to clamp the nut, and then the subsequent tapping of the nut can be performed.

[0025] When it is necessary to clamp and fix nuts of different sizes, by pulling the pull plates 201 on both sides, the locking pin 202 is moved away from the locking hole on the clamping plate 106. Then the clamping plate 106 can be slid out from the mounting shell 109. At this time, the spring 203 is in a stretched state. Then the clamping plate 106 that matches the nut is slid into the mounting shell 109. Then the pull plate 201 is released. At this time, the spring 203 quickly rebounds and drives the locking pin 202 to insert into the locking hole on the new clamping plate 106, thereby realizing the quick replacement of the clamping plate 106.

[0026] After the nut is tapped, the double-acting screw 107 is turned on by the control panel 104, so that the clamping plates 106 on both sides move away from each other. Then, the electric push rod 302 is turned on by the control panel 104. The telescopic end can drive the push frame 303 to move upward, which can push the tapped nut to the upper end of the two clamping plates 106, so that the nut can be easily removed by personnel.

[0027] According to another embodiment of the present invention, such as Figure 1 As shown, the mounting plate 102 has multiple mounting holes 103 inside. The fixing mechanism can be quickly installed onto the nut tapping machine through the mounting holes 103, ensuring that the fixing mechanism is more stable when fixing the nut for tapping.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
