Abstract
Description
Technical Field
[0001] This utility model relates to a nut fixing device for applying torque, belonging to the field of tooling and fixture technology. Background Technology
[0002] In solenoid valve assembly, torque is required to ensure that the threaded connections do not come loose during use in different environments. Traditionally, a small-diameter nut is installed on the solenoid valve body. A nut with external threads is fixed in the middle of the valve body, and this nut requires torque to ensure a secure connection. The common industry practice is to screw the nut's external threads into the solenoid valve body's internal threads, then move the valve body into a vise and tighten it. A torque wrench is used to apply torque to the nut's hexagonal head. After tightening, the valve body is released from the vise, completing one assembly cycle. This method is inefficient, requires frequent tightening and loosening of the vise, and carries the risk of deformation of the assembled product. Utility Model Content
[0003] To address the shortcomings of the existing technology, the purpose of this utility model is to provide a nut fixing device for applying torque. By setting a matching groove on the base that is compatible with the nut on the workpiece body, one end of the workpiece body and the nut on the workpiece can be inserted into the groove. The two sides of the groove can limit the relative sides of the nut. When the operator applies torque to the nut with a wrench, the two sides of the groove can limit the relative rotation of the workpiece body. When it is necessary to apply torque to the next solenoid valve, the previous solenoid valve can be directly removed from the groove. At the same time, the base can be detachably fixed to the worktable through the locking component, and the base is not easy to move when applying torque to the nut.
[0004] To achieve the above objectives, this utility model provides a nut fixing device for applying torque, comprising:
[0005] The base has at least one slot on its top, which is adapted to the nut of the workpiece. The at least one slot can engage the nut of the workpiece and limit the rotation of the nut of the workpiece.

[0019] Furthermore, as a more preferred embodiment of this utility model, the edge of the at least one slot is rounded.
[0020] A nut fixing device for applying torque has a matching groove on the base that fits the nut on the workpiece body. One end of the workpiece body and the nut on the workpiece can be inserted into the groove. The two sides of the groove can limit the relative rotation of the nut.

[0034] Example
[0035] This embodiment aims to address the shortcomings of existing technologies where the external thread of the nut 102 is screwed into the internal thread of the workpiece 100 body, the workpiece 100 body is then moved into a vise and locked in place, a torque wrench is used to apply torque to the external hexagonal head of the nut 102, and the workpiece 100 body is released from the vise, completing one assembly cycle. This assembly method is inefficient, requires frequent clamping and loosening of the vise, and carries the risk of deformation of the product assembly position. Therefore, referring to… Figure 1-4 As shown, this embodiment provides a nut fixing device for applying torque. By setting a matching groove on the base 1 that is compatible with the nut 101 on the workpiece 100 body, one end of the workpiece 100 body and the nut 101 on the workpiece 100 can be inserted into the groove. The two sides of the groove can limit the relative sides of the nut 101. When the operator applies torque to the nut 102 with a wrench, the two sides of the groove can limit the relative rotation of the workpiece 100 body. When it is necessary to apply torque to the next workpiece 100, the previous workpiece 100 can be directly removed from the groove. At the same time, the base 1 can be detachably fixed to the worktable 200 through the locking assembly 2, and the base 1 is not easy to move when applying torque to the nut 102.
[0036] Reference Figure 1-4 As shown, a nut fixing device for applying torque includes a base 1 and at least one locking component 2. The top of the base 1 has at least one slot 11, which is adapted to the nut 101 of the workpiece 100. The slot 11 can engage the nut 101 of the workpiece 100 and limit its rotation. For example, the top edge of the base 1 has six slots of different sizes, each corresponding to a nut 101 of a specific size, i.e., corresponding to each size of nut 101 on the main body of the workpiece 100. This allows for versatility for multiple workpieces 100, resulting in a wider range of applications and higher assembly efficiency. One side of the base 1 has a mounting slot 12 adapted to the at least one locking component 2; the mounting slot 12 has at least one locking component 2; the at least one locking component 2 can be detachably connected to the worktable 200. The purpose of providing the locking component 2 on the base 1 is to fix the base 1 to the worktable 200. In some embodiments, the worktable 200 is provided with a square groove, and the base 1 is a square column adapted to the square groove. Inserting into the square groove can limit its rotation when subjected to torque.
[0037] Reference Figure 1-4As shown, in some embodiments, the worktable 200 adopts a T-slot 201, and at least one locking component 2 includes a locking connector 21 and a tension spring 22. The locking connector 21 can slide out of the mounting slot 12, and its end is provided with a locking protrusion 211 that matches the T-slot 201 of the worktable 200. One end of the tension spring 22 is connected to the inner wall of the mounting slot 12, and the other end is connected to the locking connector 21. When the locking connector 21 slides out of the mounting slot 12, it overcomes the elastic force of the tension spring 22. The locking protrusion 211 can be locked into the T-slot 201 of the worktable 200. Under the action of the elastic restoring force of the tension spring 22, the locking protrusion 211 can clamp the T-slot 201 of the worktable 200, thereby fixing the base 1 on the worktable 200.
[0038] Reference Figure 1-4 As shown, in some embodiments, at least one locking component 2 further includes a travel-locking protrusion 212. At least one side of the locking connector 21 is provided with the travel-locking protrusion 212. The inner sidewall of the mounting slot 12 is provided with a travel groove 121 adapted to the travel-locking protrusion 212. When the locking connector 21 is installed into the mounting slot 12, the travel-locking protrusion 212 engages with the travel groove 121 and can slide along the travel groove 121. The travel-locking protrusion 212 ensures that the locking connector 21 slides within the mounting slot 12 while preventing it from falling out of the mounting slot 12.
[0039] Reference Figure 1-4 As shown, in some embodiments, at least one locking component 2 further includes a locking member 23. The locking connector 21 is provided with a through screw hole. The locking member 23 is threadedly connected to the screw hole. The locking member 23 can be screwed into the screw hole perpendicular to the sliding direction of the locking connector 21 and can abut against the inner wall of the mounting groove 12 to form a limiting state.

[0041] Reference Figure 1-4 As shown, in some embodiments, at least one slot 11 has a second magnetic member 112 on the other inner wall for adsorbing the end of the workpiece 100. The second magnetic member 112 can adsorb the end of the workpiece 100 so that the workpiece 100 can stand upright in at least one slot 11.
[0042] Referring to the figures, in some embodiments, at least one slot 11 has chamfers 113 on both sides of its opening, and the chamfers 113 can guide the workpiece 100 to slide into at least one slot 11.
[0043] Reference Figure 1-4 As shown, in some embodiments, the device also includes an electric magnetic accumulator 3 and a battery 4 for electrically connecting to the electric magnetic accumulator 3. The electric magnetic accumulator 3 is embedded in the bottom surface of the base 1, and a receiving groove for installing the battery 4 is provided on one side of the base 1.
[0044] Reference Figure 1-4 As shown, in some embodiments, at least one locking component 2 further includes a rotating handle 24, which is fixedly connected to the locking member 23. The rotating handle 24 can be rotated by an external force, causing the locking member 23 to rotate. In some embodiments, the edge of at least one slot 11 is rounded.
