Description

Technical Field

[0001] The utility model relates to the field of production auxiliary equipment, in particular to a thread pressing tool. Background Art

[0002] like Figure 1 As shown, the housing 10 is provided with a mounting groove 101, and a threaded hole 102 is provided on one side of the mounting groove 101. The housing 10 is also provided with a thumb screw 20 and an insert (not shown in the figure). The insert is inserted into the mounting groove 101. The thumb screw 20 is connected to the threaded hole 102 in an axially movable manner. One end of the thumb screw 20 can protrude from the groove wall of the mounting groove 101 and connect with the insert to prevent the insert from accidentally detaching from the mounting groove 101. The thumb screw 20 and the threaded hole 102 are generally threadedly connected. When installing the insert, the thumb screw 20 needs to be completely removed and then installed after the insert is in place. Since the thumb screw 20 is completely separated from the threaded hole 102, it is easy to cause the thumb screw 20 to be lost. Utility Model Content

[0003] The utility model aims to provide a thread pressing tool which can prevent screws from loosening.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a thread pressing tool, including a kit and a pressing rod, a first mounting hole and a second mounting hole are opened in the kit, the first mounting hole and the second mounting hole intersect and are connected, the first mounting hole is used to accommodate the threaded part to be pressed, and the end of the threaded part to be pressed is exposed in the second mounting hole; the pressing rod is arranged in the second mounting hole, and the pressing rod can move back and forth toward the first mounting hole to impact the threaded part to be pressed.

[0005] It can be seen from the above scheme that by setting a kit for being sleeved on the outside of the threaded end of the threaded part to be pressed, and by setting a pressure rod for locally impacting the threaded end of the threaded part to be pressed, part of the threaded end is deformed, so that the threaded part to be pressed can move back and forth along the axial direction of the mounting hole of the shell but will not completely detach from the mounting hole, which is beneficial to prevent the threaded part to be pressed from being accidentally lost.

[0006] A further solution is that a stop portion is provided at one end of the pressure rod away from the first mounting hole; a first stop surface and an elastic member are provided in the second mounting hole, the first stop surface is provided between the first mounting hole and the stop portion, and the elastic member elastically abuts between the first stop surface and the stop portion.

[0007] It can be seen from the above scheme that by providing the elastic member, on the one hand, it is beneficial to buffer the impact force of the striking rod, and on the other hand, after each impact, it can push the pressure rod backward to prepare for the next impact.

[0008] A further solution is that a second stop surface is further provided in the second mounting hole, the second stop surface is provided between the first stop surface and the stop portion, and the second stop surface and the stop portion are arranged opposite to each other and spaced apart by a preset distance.

[0009] It can be seen from the above solution that by providing the second stop surface, the normal impact movement of the pressing rod is not hindered, and the pressing rod can be prevented from moving too far, which would cause serious deformation of the threaded member to be pressed.

[0010] A further solution is that a third stop surface is provided at the bottom of the first mounting hole, and the third stop surface protrudes from the hole wall of the second mounting hole to limit the height of the screw member to be pressed exposed in the second mounting hole.

[0011] It can be seen from the above scheme that by setting the third stop surface, it is used to limit the height of the threaded part to be pressed exposed in the second mounting hole, so that the pressing rod only performs an impact operation at a position close to the end of the threaded part to be pressed, ensuring that the threaded part to be pressed can still move axially back and forth a certain distance.

[0012] A further solution is that the kit is provided with a hand-held portion at one end thereof away from the first mounting hole.

[0013] A further solution is that the thread pressing tool further includes a driving device, which can force the pressing rod to impact and move in the direction of the first mounting hole.

[0014] A further solution is that the driving device is an impact drill or a hammer tool.

[0015] A further solution is that a connecting rod is provided at the driving end of the impact drill, the connecting rod is inserted into the second mounting hole and abuts against the pressure rod, and the impact drill can drive the connecting rod to rotate and impact the pressure rod back and forth.

[0022] See also Figures 2 to 5 , and combined with Figure 1 The present embodiment provides a thread pressing tool, which includes a kit 1, a pressing rod 2, an elastic member 313 and a driving device 4.

[0023] The kit 1 is configured as an L-shaped structure and includes a first arm 11 and a second arm 12 intersecting perpendicularly. The first arm 11 is capable of extending into the mounting slot 101 of the housing 10. A first mounting hole 111 and a second mounting hole 112 are defined within the first arm 11. The first mounting hole 111 and the second mounting hole 112 intersect and communicate with each other. Preferably, the first mounting hole 111 and the second mounting hole 112 are disposed perpendicularly. The first mounting hole 111 is disposed at the end of the first arm 11 distal from the second arm 12 and is configured to accommodate a threaded component to be pressed. In this embodiment, the threaded component to be pressed is a thumb screw 20. The end of the threaded component to be inserted into the first mounting hole 111 is exposed within the second mounting hole 112.

[0024] The pressing rod 2 is arranged in the second mounting hole 112. The pressing rod 2 can move back and forth toward the first mounting hole 111 to impact the threaded part to be pressed, causing the thread on one side of the threaded part to be pressed to deform, thereby preventing the end of the threaded part to be pressed from passing through the threaded hole 102 of the shell 10, which is beneficial to prevent the threaded part to be pressed from separating from the shell 10.

[0025] A stopper 21 is provided at one end of the pressure rod 2 away from the first mounting hole 111 . The stopper 21 is disposed in the third hole segment. The outer diameter of the stopper 21 is greater than the diameter of the pressure rod 2 .

[0026] The second mounting hole 112 is set as a stepped hole, and the second mounting hole 112 includes a first hole section, a second hole section and a third hole section that are connected in sequence. A first stop surface 1121 is formed between the first hole section and the second hole section, that is, the first stop surface 1121 is arranged between the first mounting hole 111 and the stop portion 21; a second stop surface 1122 is formed between the second hole section and the third hole section, and the second stop surface 1122 is arranged between the first stop surface 1121 and the stop portion 21. The second stop surface 1122 is arranged opposite to the stop portion 21 and is spaced apart by a preset distance.

[0027] An elastic member 313 is disposed in the second mounting hole 112 and elastically abuts between the first stop surface 1121 and the stop portion 21. The elastic member 313 is preferably a compression spring and can exert a force on the stop portion 21 to move away from the first mounting hole 111.

[0028] A third stop surface 1111 is provided at the bottom of the first mounting hole 111, and the third stop surface 1111 protrudes from the hole wall of the first hole section of the second mounting hole 112, and is used to abut against the end face of the threaded part to be pressed, so as to limit the height of the threaded part to be pressed exposed in the second mounting hole 112, and ensure that the pressing rod 2 can impact a few turns of thread.

[0029] In order to facilitate the staff to hold it, the kit 1 is provided with a hand-holding portion at one end thereof away from the first mounting hole 111 . In this embodiment, the second arm 12 is the hand-holding portion.

[0030] In order to drive the pressing rod 2 to perform the impact action, the thread pressing tool of this embodiment further includes a driving device 4, which can force the pressing rod 2 to impact and move toward the first mounting hole 111. The driving device 4 is an impact drill or a hammer tool, and the hammer tool includes a hammer.

[0031] This embodiment is preferably an impact drill. The driving end of the impact drill is provided with a connecting rod 41. One end of the connecting rod 41 is inserted into the third hole section of the second mounting hole 112 and abuts against the pressure rod 2. The connecting rod 41 and the third hole section are in a clearance fit. When the impact drill is started, the connecting rod 41 rotates in the second mounting hole 112 while impacting the pressure rod 2 back and forth, causing the pressure rod 2 to impact the threads of the threaded part to be pressed, causing the threads to deform. The end of the deformed threaded part to be pressed can no longer pass through the threaded hole 102 of the housing 10, so that the threaded part to be pressed can rotate in the threaded hole 102 and move axially a small distance, but cannot escape from the threaded hole 102.

[0032] In other embodiments, one end of the pressing rod 2 may extend out of the second mounting hole 112 , so that a hammer can directly strike the pressing rod 2 outside the second mounting hole 112 , causing the pressing rod 2 to impact the threads of the threaded part to be pressed.

[0033] In summary, the utility model provides a kit 1 for being sleeved on the outside of the threaded end of the threaded part to be pressed, and provides a pressing rod 2 for locally impacting the threaded end of the threaded part to be pressed, so that part of the threaded end is deformed, so that the threaded part to be pressed can move back and forth along the axial direction of the mounting hole of the shell but will not completely detach from the mounting hole, which is beneficial to prevent the threaded part to be pressed from being accidentally lost.

[0034] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
