[0039] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] like Figures 1-4 As shown, the present invention provides a 3D printed substrate wire cutting fixture, which includes a fixed base 1, a left clamping arm 2, a right clamping arm 3, and a clamping screw 4.

[0041] The fixed base 1 has a vertical surface 101 on its front side, on which the substrate 5 is placed. Two left clamping arms 2 are provided on the left side of the vertical surface 101 to hold the left end of the substrate 5. Two path holes 102 are provided through the front and back on the right side of the vertical surface 101. Each path hole 102 is provided with a right clamping arm 3 and a tightening screw 4. The right clamping arm 3 can slide left and right in the path hole 102. The right end of the tightening screw 4 passes through the right end of the fixed base 1 and is screwed on. The left end is used to hold the right end of the right clamping arm 3 so that the right clamping arm 3 holds the right end of the substrate 5.

[0042] The fixed base 1 serves as the foundation platform for the entire fixture, providing stable support. It consists of a base plate b and a vertical plate a. The base plate b is bolted to the horizontal rail of the wire cutting equipment, and the vertical plate a is bolted to the base plate b. The vertical surface 101 is the front end face of the vertical plate a. A reinforcing rib 11 is also fixed to the back of the fixed base 1. The front end of the reinforcing rib 11 is bolted to the back of the vertical plate a, and the bottom end of the reinforcing rib 11 is bolted to the top of the base plate b. This structure enhances the structural strength of the fixed base 1.

[0043] The vertical surface 101 of the fixed base 1 is used to place the substrate 5, and the substrate 5 is clamped from left and right by the left clamping arm 2 and the right clamping arm 3. The substrate 5 is a 3D printing forming substrate, that is, the substrate 5 carries a 3D printing formed part. The tooling fixture is used to fix the substrate on a wire cutting device, and then the substrate 5 is cut by wire cutting to separate the substrate 5 from the part.

[0044] Since the right clamping arm 3 can slide left and right in the path hole 102, the distance between the left clamping arm 2 and the right clamping arm 3 is adjustable, which can be applied to clamping different sizes of substrates 5, and does not need to be punched, which is convenient.

[0045] In the tooling fixture, a resisting block 41 is further arranged in each path hole 102, wherein the resisting block 41 is slidingly arranged in the path hole 102 in the left-right direction and located between the right clamping arm 3 and the jacking screw 4; the jacking screw 4 is rotationally connected with the resisting block 41. In this structure, the right end of the jacking screw 4 has a hand wheel, and rotating the jacking screw 4 can drive the resisting block 41 to move left and right.

[0046] Specifically, the right end of the resisting block 41 is provided with a T-shaped slot 4101, and the left end of the jacking screw 4 is provided with a ring slot 401, wherein the left end of the jacking screw 4 is rotationally connected to the inside of the T-shaped slot 4101 through the ring slot 401, realizing the rotational connection between the jacking screw 4 and the resisting block 41.

[0047] In the tooling fixture, the right clamping arm 3 penetrates the path hole 102 in the front and back directions, so the right clamping arm 3 can also slide in the front and back directions. To cooperate with this structure, a through hole 103 is arranged on the vertical surface 101 and corresponds to the position of the left clamping arm 2, and the left clamping arm 2 penetrates the through hole 103 in the front and back directions. Meanwhile, a connecting plate 21 and a left jack 22, as well as a locking block 31 and a right jack 32 are also arranged. In addition, a left limiting protrusion 201 and a right limiting protrusion 301 are also arranged.

[0048] The front end of the left clamping arm 2 is bent to the right to form the left limiting protrusion 201, one end of the connecting plate 21 is fixedly connected to the rear end of one of the left clamping arms 2, and the other end is fixedly connected to the rear end of the other left clamping arm 2. The left jack 22 is screwed in the middle part of the connecting plate 21, and the front end thereof is used to resist the back of the fixed base 1, so that the left limiting protrusion 201 resists the front end of the substrate 5. By screwing the left jack 22 to move forward, the left clamping arm 2 can be driven to move backward, and then the left limiting protrusion 201 resists the front end of the substrate 5, realizing front and back clamping.

[0049] The front end of the right clamping arm 3 is bent to the left to form a right limiting protrusion 301, and a locking block 31 is fixedly connected to the rear end of the right clamping arm 3. Two right top screws 32 are screwed on the locking block 31 and are located on the upper and lower sides of the path hole 102. The front ends of the two right top screws 32 are used to abut against the back of the fixed base 1, so that the right limiting protrusion 301 abuts against the front end of the substrate 5.

[0050] When clamping, the right clamping arm 3 is driven to move rearward by screwing the right top screw 32 to move forward, so that the right limiting protrusion 301 abuts against the front end of the substrate 5, and front and rear clamping is realized.

[0051] The left limiting protrusion 201 and the right limiting protrusion 301 are convenient for limiting the front and rear ends of the substrate 5, preventing the substrate 5 from loosening or deviating during cutting, and effectively improving the cutting precision.

[0052] It should be noted that in actual application, an electric push rod can be used instead of the jacking screw 4 to realize the left and right movement of the abutting block 41. The output end of the electric push rod extends into the path hole 102, and the abutting block 41 is rotationally connected by using the T-shaped slot 4101 and the ring slot 401 structure, and the shell of the electric push rod is fixedly connected to the fixed base 1.

[0053] The use method of the 3D printing forming substrate wire cutting tool clamp of the utility model is as follows:

[0054] The fixed base 1 is fixed on the cross rail of the wire cutting equipment by using a bolt, the abutting block 41 is separated from the right clamping arm 3 by screwing the jacking screw 4, and the spacing between the left clamping arm 2 and the right clamping arm 3 is adjusted according to the size of the substrate 5.

[0055] The substrate 5 to be processed is placed on the vertical surface 101, and then the left end of the abutting block 41 is lightly abutted against the right end of the right clamping arm 3 by screwing the jacking screw 4. Then, the left clamping arm 2 is driven to move rearward by screwing the left top screw 22 until the left limiting protrusion 201 abuts against the front end of the substrate 5. Then, the right clamping arm 3 is driven to move rearward by screwing the right top screw 32 until the right limiting protrusion 301 abuts against the front end of the substrate 5, and front and rear clamping of the substrate 5 is realized. Finally, the right end of the abutting block 41 is jacked against the right end of the right clamping arm 3 by screwing the jacking screw 4 again, so that the left clamping arm 2 and the right clamping arm 3 clamp the substrate 5 from the left and right sides.

[0056] The above only describes the preferred embodiment of the utility model, and does not limit the utility model. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
