[0023] Please refer to Figure 8 and Figure 9 This embodiment discloses a positioning fixture 100 for positioning a car seat base 500. The base 500 includes at least two first positioning surfaces arranged opposite each other along the X-axis and positioning holes extending along the Y-axis. The positioning fixture 100 includes at least two first positioning members 110 arranged opposite each other along the X-axis, a second positioning member 120 extending along the Y-axis, and a third positioning member 130.

[0024] The first positioning member 110 is provided with a support portion 112 and a second positioning surface 111. The support portion 112 is used to abut against the base 500 along the positive Z-axis. When the support portion 112 abuts against the base 500 along the positive Z-axis, the second positioning surface 111 abuts against the corresponding first positioning surface. For example, the X-axis direction can be understood as the length direction of the positioning fixture 100, the Z-axis direction can be understood as the height direction of the positioning fixture 100, the positive Z-axis direction can be understood as the vertically upward direction, and the negative Z-axis direction can be understood as the vertically downward direction.

[0025] The second positioning element 120 is configured to move relative to the base 500 along the Y-axis direction after the second positioning surface 111 abuts against the first positioning surface, so as to extend into the positioning hole. Exemplarily, the Y-axis direction can be understood as the width direction of the positioning fixture 100, and the second positioning element 120 can be specifically set as a positioning pin.

[0026] The third positioning member 130 is configured to move relative to the base 500 along the Z-axis direction after the second positioning surface 111 abuts against the first positioning surface, so as to abut against the side of the base 500 away from the support portion 112.

[0027] In this embodiment, the positioning steps of the base 500 are as follows: First, the base 500 is placed on the first positioning member 110, so that the supporting part 112 on the first positioning member 110 supports the base 500 upwards, while the second positioning surface 111 abuts against the first positioning surface; then, the second positioning member 120 is inserted into the positioning hole, so that the peripheral wall of the second positioning member 120 abuts against the inner wall of the positioning hole, and the third positioning member 130 presses the base 500 downwards. In this way, the positioning of the base 500 is completed.

[0028] Importantly, when the base 500 is placed on the first positioning member 110, the first positioning surface and the second positioning surface 111 abut against each other to initially position the base 500. Then, the second positioning member 120 extends into the positioning hole to achieve precise positioning, and the third positioning member 130 presses the base 500 downward to prevent it from shaking during drilling. In this way, by utilizing the original first positioning surface on the base 500 and achieving initial positioning through the action of placing the base 500, and by utilizing the original positioning hole on the base 500 to achieve precise positioning, the structure of the positioning fixture 100 is simplified, and the positioning operation is made faster and more convenient.

[0029] Please refer to Figure 1 and Figure 8 The positioning fixture 100 in this embodiment further includes: a first driver 121 for driving the second positioning member 120 to move along the Y-axis; a second driver 132 for driving the third positioning member 130 to move along the Z-axis; and a control switch for simultaneously or separately controlling the first driver 121 and the second driver 132. For example, the control switch can be specifically configured as a control button, a control key on an operation screen, or a mechanical lever; both the first driver 121 and the second driver 132 can be configured as a motor, a cylinder, or a hydraulic cylinder.

[0030] In this embodiment, the first driver 121 and the second driver 132 can be controlled simultaneously using the same control switch, so that the second positioning member 120 and the third positioning member 130 can synchronously abut against the base 500, thereby saving positioning time and improving positioning efficiency. In some other embodiments, the first driver 121 and the second driver 132 can be controlled separately using independent control switches to facilitate individual positioning in different directions.

[0031] In summary, the positioning fixture 100 of this embodiment only requires the following two steps when positioning the base 500: First, place the base 500 on the first positioning member 110; second, trigger the control switch, the first driver 121 drives the second positioning member 120 to extend into the positioning hole, and the second driver 132 drives the third positioning member 130 to press the base 500 downward. In this way, the positioning of the base 500 can be completed, which is very convenient and efficient.

[0032] Please refer to Figure 8 The second positioning surface 111 gradually tilts or bends away from the base 500 along the positive direction of the Z-axis. For example, the second positioning surface 111 can be set as an inclined plane or a curved arc surface.

[0033] Specifically, the second positioning surface 111 gradually tilts or bends outward from bottom to top. This tilting or bending direction has the following advantages: the distance between the two opposing second positioning surfaces 111 gradually decreases from top to bottom, and the distance between the upper ends of the two second positioning surfaces 111 is larger. This eliminates the need for the lower end of the base 500 to be completely aligned with the area between the two second positioning surfaces 111, reducing the difficulty of operation. Simultaneously, during the process of placing the base 500 from top to bottom, the second positioning surface 111 can abut against the first positioning surface, and the two positioning surfaces can slide relative to each other. This allows the position of the base 500 to be corrected through the second positioning surface 111 until the second positioning surface 111 is completely in contact with the first positioning surface. In this way, the placement of the base 500 is combined with the initial positioning, simplifying the positioning process.

[0034] Please continue to refer to Figure 8 The second positioning member 120 has two ends arranged opposite each other along the Y-axis direction, and a first position located between the two ends. The second positioning surface 111 gradually bends or tilts towards the base 500 from the first position toward the two ends. For example, the first position is located at the middle of the second positioning surface 111 along the Y-axis direction, so that the second positioning surface 111 can be symmetrical about the first position along the Y-axis, and the force on each position of the second positioning surface 111 is more uniform.

[0035] Of particular note is that the second positioning surface 111 gradually curves or tilts inward from the first position towards both ends, thereby providing an inward convergence and constraint effect on the base 500. This effectively improves positioning accuracy and enhances the fixing strength after positioning, preventing the base 500 from shaking during subsequent processing. Furthermore, if the second positioning surface 111 is set as a curved surface with gradually changing curvature at various positions, the positions of the second positioning surface 111 with different curvatures can abut against the base 500 along a tangent direction perpendicular to that position. Each second positioning surface 111 can position the base 500 in multiple different directions. This further improves positioning accuracy.

[0036] In this embodiment, each of the first positioning members 110 has a second positioning surface 111 at both ends, so the two first positioning members 110 include four second positioning surfaces 111. The four second positioning surfaces 111 are located at the four corners of the base 500 and abut against the first positioning surface in the direction toward the inside of the base 500 to achieve the initial positioning of the base 500.

[0037] It should be noted that the upper part of the base 500 has an irregular shape and multiple hollow areas. If the third positioning component 130 is directly pressed against the upper part (i.e., the highest position) of the base 500, it may cause the contact area between the base 500 and the third positioning component 130 to be too small and thus damaged. At the same time, the parts near the hollow areas are prone to deformation and damage.

[0038] Based on this, please refer to Figure 7 In this embodiment, at least two positioning portions are provided on the base 500. Each positioning portion has a first surface and a second surface that are opposite to each other along the Z-axis. The positioning fixture 100 also includes a movable member 131 that can move relative to the base 500 along the Z-axis. At least two third positioning members 130 are disposed opposite to the movable member 131 along the X-axis and can move with the movable member 131 along the negative Z-axis to abut against the second surface. The supporting portion 112 abuts against the first surface along the positive Z-axis.

[0039] Specifically, in this embodiment, the third positioning member 130 is vertically mounted on the moving member 131. When the moving member 131 moves downward, the third positioning member 130 can reach a deeper position, allowing it to abut against the upper surface (second surface) of the positioning part. Simultaneously, since the supporting part 112 abuts against the lower surface (first surface) of the positioning part, the supporting part 112 and the third positioning member 130 can simultaneously abut against the same part (positioning part) of the base 500 on opposite sides. The first and second surfaces of the positioning part have large flat areas, and there are no open areas between them. Therefore, while achieving positioning, the base 500 can be effectively prevented from being crushed by the third positioning member 130.

[0040] Furthermore, at least two second positioning elements 120 are provided, and the at least two second positioning elements 120 are arranged opposite each other along the Y-axis direction. Specifically, the two second positioning elements 120 arranged opposite each other along the Y-axis direction can simultaneously extend into the positioning holes on both sides of the base 500, thereby counteracting the frictional force along the Y-axis generated when the second positioning elements 120 rub against the positioning holes, and preventing the base 500 from shifting along the Y-axis direction when the second positioning elements 120 extend into the positioning holes.

[0041] Please refer to Figures 1 to 7 This embodiment also discloses a drilling device, including: a positioning fixture 100; a first drilling assembly 200 and a second drilling assembly 300 arranged opposite to each other along the X-axis direction, the first drilling assembly 200 including a first drill bit 210 for drilling along the X-axis direction, and the second drilling assembly 300 including a second drill bit 310 for drilling along the X-axis direction.

[0042] Please refer to Figure 5In this embodiment, the first drilling assembly 200 further includes: a first slide rail 230 extending along the X-axis; a first mounting member 240 slidable along the first slide rail 230; a first drill bit 210 disposed on the first mounting member 240; and a third driver 220 for driving the first mounting member 240 to slide along the first slide rail 230. The third driver 220 drives the first mounting member 240 to slide along the first slide rail 230, thereby causing the first drill bit 210 on the first mounting member 240 to move along the X-axis, thus enabling the first drill bit 210 to drill a hole along the X-axis. After drilling is completed, the third driver 220 drives the first mounting member 240 to move in the opposite direction, and causes the first drill bit 210 to exit the drilled hole. Furthermore, two first drill bits 210 are simultaneously disposed on the first mounting member 240, allowing both drill bits 210 to drill simultaneously, thereby improving drilling efficiency.

[0043] Please refer to Figure 6 In this embodiment, the second drilling assembly 300 further includes: a second slide rail 320 extending along the Y-axis; a second mounting member 340 slidable along the second slide rail 320; a second drill bit 310 disposed on the second mounting member 340; and a fourth driver 360 for driving the second mounting member 340 to slide along the second slide rail 320. The fourth driver 360 can drive the second mounting member 340 to move along the Y-axis, thereby moving the second drill bit 310 on the second mounting member 340 to different positions aligned with the base 500, thus enabling drilling at different positions on the base 500.

[0044] Please continue to refer to Figure 6 In this embodiment, the second drilling assembly 300 further includes: a third slide rail 330 disposed on the second mounting member 340 and extending along the X-axis direction; a third mounting member 350, which is slidable along the third slide rail 330; a second drill bit 310 disposed on the third mounting member 350; and a fifth driver 370 for driving the third mounting member 350 to slide along the third slide rail 330. The fifth driver 370 drives the third mounting member 350 to slide along the third slide rail 330, thereby causing the second drill bit 310 on the third mounting member 350 to move along the X-axis direction, thus enabling the second drill bit 310 to drill a hole along the X-axis direction. After drilling is completed, the fifth driver 370 drives the third mounting member 350 to move in the opposite direction and causes the second drill bit 310 to exit the drilled hole.

[0045] Please refer to Figure 1 The drilling device also includes a worktable 400, a positioning fixture 100, a first drilling assembly 200, and a second drilling assembly 300, all of which are mounted on the worktable 400. The worktable 400 is equipped with casters at its bottom, allowing the drilling device to be moved to different positions for operation, making it more flexible to use.
