DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0020] Specific implementation case:

[0021] For example, Figure 1As shown, a drilling and positioning device for fixing seat processing includes a housing 1, a lateral limiting mechanism 2 is installed on the housing 1, and a positioning mechanism 3 is installed on the housing 1, and the positioning mechanism 3 is installed above the lateral limiting mechanism 2;

[0022] The lateral limiting mechanism 2 is used to clamp and position the sides of the rectangular fixing seat, and the positioning mechanism 3 is used to position and fix the other two outer walls of the fixing seat;

[0023] like Figure 2 As shown, a workbench 11 is installed in the housing 1;

[0024] The lateral limiting mechanism 2 includes a fixed block 21, which is installed above the workbench 11. A plurality of groups of second springs 22 are installed at the front end of the fixed block 21, and a push plate 23 is installed at the front end of the second spring 22.

[0025] A step 12 is provided above the workbench 11, and the position of the step 12 is opposite to the lateral limiting mechanism 2;

[0026] When the workpiece is placed on the workbench 11, one side of the fixed seat presses against the push plate 23, and the second spring 22 compresses the push plate 23 toward the fixed block 21. The other side of the fixed seat contacts the step 12, and the second spring 22 pushes the push plate 23 against the fixed seat, thereby completing the lateral directional preliminary clamping.

[0027] The positioning mechanism 3 includes a mounting frame 31, with a central plate 311 mounted at its center. A first spring 33 is mounted at each end of the central plate 311. A studded screw 32 is mounted on a bearing at the center of the central plate 311. The studded screw 32 is mounted within the first spring 33, and the threads at both ends of the studded screw 32 are opposite. A transmission frame 34 is mounted at each end of the studded screw 32. The first spring 33 is fixedly connected to the transmission frame 34. An interference block 35 is mounted on the transmission frame 34. A manual adjustment device (not shown) is mounted on one end of the studded screw 32.

[0028] The positioning mechanism 3 is provided with two groups, and the two groups of the positioning mechanism 3 are symmetrically installed;

[0029] After the lateral limiting mechanism 2 has been used for preliminary clamping in a lateral direction, the operator first manually rotates the manual adjustment device so that the double-headed screw 32 is rotated and the transmission frames 34 installed at both ends thereof simultaneously move toward the center due to the opposite threads, and the movement distances are equal. When the transmission frame 34 on one side contacts the outer wall of the fixed seat, it pushes the fixed seat to move in the lateral direction defined by the lateral limiting mechanism 2 until the other end contacts the other abutment block 35, thus completing the center positioning. The provision of the first spring 33 strengthens the stability of the structure and makes the clamping force of the abutment block 35 stronger.

[0030] The inner side of the abutment block 35 is provided with an anti-slip rubber pad (not shown in the figure) for enhancing the clamping force during clamping;

[0031] A protective shell 4 is installed on the mounting frame 31 to protect its internal structure;

[0032] To sum up, by tightening the push plate 23 by the second spring 22 and moving it closer to the fixed block 21, the other side of the fixed seat is connected to the step 12, and the second spring 22 pushes the push plate 23 against the fixed seat, thereby completing the preliminary lateral directional clamping. The operator first manually rotates the manual adjustment device to rotate the double-headed screw 32 and the transmission frames 34 installed at both ends thereof move closer to the center at the same time because of the opposite threads. When one side of the transmission frame 34 contacts the outer wall of the fixed seat, it pushes the fixed seat to move in the lateral direction defined by the lateral limit mechanism 2 until the other end contacts the other interference block 35, thereby achieving the center positioning effect of the fixed seat processing.

[0033] The above description is merely a preferred embodiment of the present application. The scope of protection of the present application is not limited to the above embodiment. All technical solutions based on this concept fall within the scope of protection of the present application. It should be noted that for those skilled in the art, improvements and modifications that do not depart from the principles of the present application should also be considered within the scope of protection of the present application.
