[0026] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0027] The following is combined with Figure 1-Figure 6 This embodiment is described in further detail.

[0028] See also Figure 1-Figure 3In this embodiment, an anti-bias drilling device for processing 3D printer parts includes a workbench 100, a telescopic rod 120 is provided on the upper end surface of the workbench 100, a connecting block 121 is provided on the telescopic rod 120, and a rotatable drill 122 is provided on the connecting block 121; the upper end surface of the workbench 100 is relatively provided with mutually perpendicular sliding grooves 110, a movable sliding block 350 is provided in the sliding groove 110, and a clamping assembly for clamping a side plate 130 is provided on the sliding block 350; the clamping assembly includes a first clamping jaw 300 fixedly provided on the sliding block 350 and a second clamping jaw 310 movably provided on the sliding block 350, a plurality of positioning holes 111 are further provided on the bottom wall of the sliding groove 110, and a positioning assembly is further provided in the sliding block 350, and the positioning assembly includes a U-shaped rod 341 that can extend into the corresponding positioning holes 111.

[0029] In this embodiment, the four sides of the 3D printer side plate 130 to be drilled are placed on the corresponding first clamping jaw 300, and the second clamping jaw 310 is moved downward so that the first clamping jaw 300 and the second clamping jaw 310 cooperate with each other to clamp them, thereby achieving the fixing of the 3D printer side plate 130 to be drilled on the workbench 100. At this time, the telescopic rod 120 is started to drive the connecting block 121 to move downward, and the drilling machine 122 is started at the same time, so as to better achieve the drilling operation of the side plate 130. After the drilling of the side plate 130 is completed, the side plate 130 and the frame can be assembled by screws to form the shell of the 3D printer;

[0030] Among them, two clamping assemblies are relatively arranged in each sliding groove 110, so that the four clamping assemblies can fix the four sides of the side plate 130. Compared with the existing ones, the clamping assemblies in this embodiment have a better fixing effect, and the side plate 130 will not be offset due to the vibration of the drilling machine 122 during drilling, thereby affecting the drilling effect;

[0031] Among them, a plurality of positioning holes 111 are arranged along the extending direction of the corresponding sliding groove 110. Through the arrangement of the positioning holes 111 and the U-shaped rod 341, in actual use, when the U-shaped rod 341 is retracted into the sliding block 350, it is separated from the corresponding positioning hole 111. At this time, the fixing of the sliding block 350 is released, so that it can slide along the sliding groove 110, that is, the clamping assembly can be moved, and then the distance between the clamping assemblies is adjusted to adapt to side panels 130 of different sizes. When the U-shaped rod 341 extends out of the sliding block 350 and extends into the positioning hole 111, at this time, the position of the clamping assembly is fixed, and then the position of the side panel 130 is fixed, so as to prevent the side panel 130 from being displaced during drilling, thereby affecting the drilling accuracy.

[0032] The second clamping jaw 310 is controlled to move up and down to move away from or close to the first clamping jaw 300, so as to better clamp and fix the side plate 130 by the clamping assembly, and at the same time, it is also convenient to take and place the side plate 130 on the clamping assembly.

[0033] like Figure 4-Figure 6 As shown, in this embodiment, a movable cavity 330 is provided in the sliding block 350, and a vertical groove 500 is provided on the side wall opposite to the movable cavity along the height direction of the sliding block 350. The second clamping jaw 310 is arranged in the movable cavity 330 so as to be liftable. A vertical block 410 which moves in the corresponding vertical groove 500 is provided on the side wall opposite to the second clamping jaw 310. The second clamping jaw 310 which is located in the movable cavity 330 is provided with an inclined T-slot 311. A horizontally movable driving block 320 is also provided in the movable cavity 330. A T-block 321 which moves in the T-slot 311 is provided on the driving block 320. The T-block 321 is located in the T-slot 311 and moves to drive the second clamping jaw 310 to move up and down in the movable cavity 330.

[0034] In actual use, the cross section of the sliding groove 110 of this embodiment is T-shaped, the lower end of the sliding block 350 is provided with a sliding portion sliding in the sliding groove 110, and the upper end of the sliding block 350 is extended out of the sliding groove 110. At the same time, the opposite side of the sliding block 350 is provided with a notch connected to the moving cavity 330 along its height direction. The notch is used to facilitate one end of the second clamping jaw 310 to extend into the moving cavity 330.

[0035] In this embodiment, by setting the vertical slot 500 and the vertical block 410, the second clamping jaw 310 is restricted so that it can only move up and down along the vertical slot 500 in the movable cavity 330; wherein, by setting the T-slot 311, the driving block 320 and the T-block 321, the driving block 320 can move back and forth in the horizontal direction in the movable cavity 330, that is, the cooperation between the T-block 321 and the T-slot 311 is utilized to realize the lifting and lowering of the second clamping jaw 310 in the movable cavity 330, thereby better realizing the second clamping jaw 310 approaching or moving away from the first clamping jaw 300.

[0036] like Figure 6 As shown, in this embodiment, a first inclined surface 411 is provided on the second clamping jaw 310 , and a second inclined surface matching the first inclined surface 411 is also provided on the driving block 320 .

[0037] In this embodiment, when the driving block 320 moves, the first inclined surface 411 and the second inclined surface can cooperate with each other, so that the driving block 320 and the second clamping jaw 310 can slide and fit together, so that the cooperation and movement between the two is more stable.

[0038] like Figure 3-Figure 4As shown, in this embodiment, a driving cavity 340 is provided on the side of the sliding block 350 that is away from each other. A screw rod 345 is provided in the driving cavity 340, one end of which extends out and is threaded through the driving block 320. The screw rod 345 rotates to drive the driving block 320 to move horizontally in the moving cavity 330.

[0039] In this embodiment, the opening of the driving cavity 340 faces the side away from the sliding block 350, and a detachable blocking plate 430 is provided at the opening. The screw rod 345 passes through the blocking plate 430 and the driving cavity 340 and extends into the moving cavity 330. The blocking plate 430 and the side walls of the driving cavity 340 are provided with bearings for mounting the screw rod 345. At the same time, the size of the driving block 320 is adapted to the size of the driving cavity 340, that is, the side walls of the driving block 320 and the side walls of the driving cavity 340 are slidingly fitted. Therefore, when the screw rod 345 rotates, it can drive the driving block 320 to move horizontally in the moving cavity 330, thereby driving the second clamping jaw 310 to move up and down.

[0040] The blocking plate 430 is fixedly mounted on the sliding block 350 by screws, thereby enabling the installation of the components in the driving cavity 340 to be better realized;

[0041] In actual use, in order to facilitate the operator to rotate the screw rod 345, a gripping portion 400 is provided at the protruding end of the screw rod 345.

[0042] like Figure 5 As shown, in this embodiment, a locking hole is provided on the bottom wall of the driving cavity 340 corresponding to the positioning hole 111, and the U-shaped rod 341 can be raised and lowered in the driving cavity 340, and the bottom end of the U-shaped rod 341 can extend into the corresponding positioning hole 111 through the locking hole.

[0043] In this embodiment, the locking hole is provided so that the U-shaped rod 341 can extend or retract into the driving cavity 340, thereby fixing or releasing the position of the clamping assembly.

[0044] like Figure 5 As shown, in this embodiment, a baffle 343 adapted to the driving cavity 340 is provided at the top end of the U-shaped rod 341, and a spring 344 for driving the baffle 343 to move downward is also provided in the driving cavity 340, and movable grooves 342 are provided on the opposite side walls of the driving cavity 340, and a movable block 420 extending at both ends and movable in the corresponding movable groove 342 is provided on the baffle 343.

[0045] Through the structure of this embodiment, when it is necessary to release the fixing of the sliding block 350, the moving block 420 can be lifted along the moving groove 342, and the baffle 343 drives the U-shaped rod 341 to move upward, so that the lower end of the U-shaped rod 341 extends out of the corresponding positioning hole 111. At this time, when the sliding block 350 can be moved along the sliding groove 110 to the desired position, the moving block 420 is released, and the baffle 343 moves downward under the action of the spring 344, thereby driving the U-shaped rod 341 to extend into the corresponding positioning hole 111, thereby fixing the position of the sliding block 350;

[0046] Among them, since the movable groove 342 is set along the height direction of the sliding block 350 and it limits the movable block 420, the baffle 343 will not rotate when it is raised or lowered in the driving chamber 340, so that the U-shaped rod 341 can always remain aligned with the positioning hole 111 without affecting its use, and the bottom end of the U-shaped rod 341 will not interfere with the screw rod 345 when moving, thereby affecting the normal use of the two.

[0047] Working principle: When the side plate 130 to be drilled needs to be drilled, first, one side edge of the side plate 130 is overlapped on the upper end surface of the corresponding first clamping jaw 300, and then the moving block 420 is lifted along the moving groove 342, so that the baffle 343 drives the U-shaped rod 341 to move upward, so that the lower end of the U-shaped rod 341 extends out of the positioning hole 111, and at this time, the sliding block 350 is moved along the sliding groove 110 to move the first clamping jaw 300 to the corresponding side edge of the side plate 130 to drill it. Support, then, release the moving block 420, so that the baffle 343 moves downward under the action of the spring 344, and then drives the U-shaped rod 341 to extend into the corresponding positioning hole 111, thereby achieving the position fixation of the sliding block 350; then, rotate the corresponding screw rod 345 to move the second clamping jaw 310 downward, and then fix the side plate 130, so that the four sides of the side plate 130 are fixed. At this time, the telescopic rod 120 and the drilling rig 122 can be started to drill holes in the side plate 130.
