[0039] Example

[0040] It should be noted that the T-slot includes a strip-shaped cavity located below the surface of the T-slot workbench, and a T-slot gap connecting the strip-shaped cavity with the external space. The arrangement of the T-slot gap enables the T-slot workbench directly above the strip-shaped cavity to form a relative convex groove structure.

[0041] See also Figures 1 to 7 The embodiment of the present application shown provides a T-nut, which is placed in a T-slot in actual application. After the workpiece / tool ​​is connected to the T-nut through a screw rod, the screw rod is tightened to make the T-nut press against the T-slot, thereby achieving the fixation of the workpiece / tool ​​and the T-slot table; see details. Figures 1 to 3 The T-nut comprises: a nut body 1, a stopper 2 and a stopper 3;

[0042] The nut body 1 is a columnar structure as a whole, and a plurality of planes are arranged on its side, including: a first plane 11, a second plane 12, a third plane 13, and a fourth plane 14; wherein the first plane 11 is parallel to the third plane 13, and the second plane 12 is parallel to the fourth plane 14; and the distance between the first plane 11 and the third plane 13, and the distance between the second plane 12 and the fourth plane 14 are both smaller than the width of the T-slot gap. With this design, when the first plane 11 and the third plane 13 are parallel to the T-slot gap or the second plane 12 and the fourth plane 14 are parallel to the T-slot gap, the nut body 1 located in the T-slot gap can slide relative to the T-slot; the stopper 2 is arranged on the side of the nut body 1, The stopper 3 is arranged on the bottom surface of one side of the nut body 1, and a screw hole 31 matching with the lead screw is provided on the surface of the stopper 3 away from the nut body 1, and a slot 32 is formed between the stopper 3 and the stopper 2; when in use, the T-nut is engaged with the T-slot through the slot 32, and the stopper 3 is located above the table top of the T-slot workbench; with this technical solution, the position of the stopper 3 located above the table top of the T-slot workbench is clear and definite, which is convenient for the operator to connect the lead screw to the screw hole 31, and by moving the stopper 3, the T-nut can slide along the T-slot gap to realize the position adjustment of the T-nut, which solves the technical problems in the prior art that the position of the screw hole 31 is difficult to determine after the T-nut sinks to the bottom of the T-slot, and the position adjustment of the T-nut is inconvenient.

[0043] See also Figures 1 to 4 As a preferred embodiment of the present application, the first plane 11 and the second plane 12 are connected by a first arc surface 15, and the third plane 13 and the fourth plane 14 are connected by a second arc surface 16; wherein, the distance between the first arc surface 15 and the second arc surface 16 is smaller than the width of the T-slot gap; adopting this technical solution, not only can the nut body 1 be placed in the T-slot gap, but also can be rotated a certain angle in the T-slot.

[0044] In the above technical solution, if Figure 1 As shown, the blocking portion 2 includes: a first boss 21 and a second boss 22; the first boss 21 and the second boss 22 are both columnar structures, and the cross section is trapezoidal; wherein the first boss 21 is arranged on the first plane 11, and the plane of the first boss 21 away from the fourth plane 14 is connected with the second plane 12 to form the same plane; the second boss 22 is arranged on the third plane 13; the plane of the second boss 22 away from the second plane 12 is connected with the fourth plane 14 to form the same plane; with this design, when the second plane 12 and the fourth plane 14 of the nut body 1 are parallel to the T-slot gap, the blocking portion 2 can be placed in the T-slot together with the nut body 1;

[0045] More specifically, the plane of the first boss 21 away from the nut body 1 is the first abutment plane 211, and the plane of the second boss 22 away from the nut body 1 is the second abutment plane 221; the distance between the first abutment plane 211 and the second abutment plane 221 is greater than the width of the T-slot gap, so that when the T-nut is placed in the T-slot, the nut body 1 is rotated, and the blocking portion 2 is staggered with the T-slot gap. At this time, if the screw applies an upward force to the T-nut, the blocking portion 2 will abut against the surface of the T-slot, so that the T-nut cannot be pulled out of the T-slot gap, thereby achieving a locking effect; after use, loosen the screw, rotate the nut body 1 to adjust the second plane 12 and the fourth plane 14 to an angle parallel to the T-slot gap, and take out the T-nut.

[0046] Using the above technical solution, such as Figure 6 As shown, the operator can place the T-nut at any position in the T-slot gap without having to slide it into the end face notch of the T-slot each time; the T-nut can be fixed in the T-slot by rotating it, and can be easily removed after use, which greatly improves the flexibility of the T-nut; it solves the technical problem in the related art that if a T-nut needs to be temporarily installed or removed in a T-slot, part of the workpiece / tooling must be removed, affecting the processing flow.

[0047] It can be understood that when the nut body 1 is rotated to engage the T-nut with the T-slot, the design of the abutment plane 21 enables it to fit tightly with the inner wall of the T-slot, thereby increasing the contact area between the abutment portion 2 and the T-slot, thereby ensuring the abutment stability between the T-nut and the T-slot; the abutment portion 2 is arranged at the end of the nut body 1 away from the stop block 3, and the bottom surface of the abutment portion 2 is connected to the bottom surface of the nut body 1 to form the same plane; adopting this technical solution, the contact area between the bottom surface of the T-nut and the bottom of the T-slot can be increased, thereby further enhancing the abutment stability between the T-nut and the T-slot.

[0048] See also Figure 3 and Figure 7 In this embodiment, the stopper 3 is a rectangular block structure as a whole, and the bottom surface of the stopper 3 close to the nut body 1, the side surface of the nut body 1, and the bottom surface of the stopper 2 close to the nut body 1 together form a slot 32; a plurality of plane groups are provided on the side of the stopper 3, and the plane group includes two parallel stopper planes; the distance between the two stopper planes in any plane group is greater than the width of the T-slot gap, so that the stopper 3 always abuts above the T-slot gap; when the T-nut is rotated, the stopper 3 and the stopper 2 are synchronously staggered from the T-slot gap, and the convex groove structure of the T-slot workbench is clamped in the slot 32.

[0049] As an implementation mode of the present application, the screw hole 31 passes through the block 3 and extends into the nut body 1 to increase the distance that the lead screw can extend into the screw hole 31 and improve the connection strength between the T-nut and the lead screw.

[0050] A T-nut provided in the present application is provided with a stopper 3 and keeps the stopper 3 always located above the T-slot, so that the position of the screw hole 31 is clearly visible, thereby improving the convenience of moving the T-nut and the accuracy of the connection between the lead screw and the T-nut; by providing a card slot 32 to be firmly connected with the T-slot, and arranging the nut body 1 and the stopper 2 as a structure that can be removed from the gap of the T-slot, the technical problem in the related art that part of the workpiece / tooling must be dismantled when adding or removing the T-nut, which affects the processing flow, is solved, and the flexibility of use of the T-nut is improved.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
