Description

Technical Field

[0001] This application relates to the field of drilling technology, specifically to a fixed tooling for drilling. Background Technology

[0002] Drilling refers to the operation of creating holes in solid materials using a drill bit. When drilling, a fixture is needed to hold the workpiece in place, ensuring stable drilling. However, these fixtures typically only clamp the workpiece from both sides. Since the workpiece vibrates in all directions during drilling, clamping only from both sides causes it to move in other directions, resulting in drill deviation and reduced workpiece quality.

[0003] Therefore, there is an urgent need for a fixed tooling for drilling to solve the problem of drilling deviation caused by workpiece vibration. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a fixed tooling for drilling, which has the advantage of improving the drilling stability of the workpiece and solving the problem of drilling deviation caused by workpiece vibration.

[0005] To achieve the above objectives, this application provides the following technical solution: a fixing fixture for drilling, including a base, a fixing mechanism on the top of the base, and a clamping mechanism on the outside of the base;

[0006] The fixing mechanism includes a spiral disk, a spiral seat, a connecting block, a guide rod, and a clamping plate. The spiral disk is rotatably connected to the outer surface of the base via bearings. The spiral seat is slidably connected to the slide rail at the top of the spiral disk. The two ends of the connecting block are welded to the bottom of the spiral seat and one end of the guide rod. The clamping plate is fixedly connected to the other end of the guide rod by bolts.

[0007] The spiral seat drives the guide rods and clamping plates to move through the connecting block. When the four sets of guide rods and clamping plates move inward, they can clamp the workpiece from all sides, thereby fixing the workpiece and allowing it to be drilled stably without easily shifting, thus improving the drilling accuracy of the workpiece.

[0008] Preferably, a support plate is welded to the outer side of the base, and a drive motor is installed at the bottom of the support plate. A gear is fixedly connected to the output end of the drive motor, and the gear meshes with the spiral disk.

[0009] Preferably, the outer surface of the guide rod is provided with a protrusion, and a fixing block is slidably connected to the outer surface of the guide rod, the fixing block being welded to the top of the base.

[0010] Preferably, the four sets of spiral seats are located on the top of the spiral disk in a rectangular distribution.

[0011] Preferably, the clamping mechanism includes a support base, a second drive motor, and a pressure plate. The support base is welded to the outer surface of the base, the second drive motor is installed on the outside of the support base, one end of the inner rod of the pressure plate is fixedly connected to the output end of the second drive motor, and the other end of the inner rod of the pressure plate is rotatably connected to the inside of the support base.

[0012] Preferably, the pressure plate is a U-shaped plate.

[0013] In summary, this application includes at least one of the following beneficial effects:

[0014] 1. This drilling fixture is fixed. When the workpiece is placed on the top of the base, the spiral disc rotates and can drive the spiral seat to move inward or outward. When the spiral seat moves, it drives the guide rod and clamping plate to move through the connecting block. When the four sets of guide rods and clamping plates move inward, they can clamp the workpiece around its perimeter, thereby fixing the workpiece and allowing it to be drilled stably without deviation, thus improving the drilling accuracy of the workpiece.

[0015] 2. The drilling fixture is fixed. When the workpiece is placed on the top of the base, by adjusting the angle of the pressure plate, when the pressure plate rotates inward, one end of the pressure plate can press against the top of the workpiece, so that the workpiece will not move up and down, causing the workpiece to be deviated during drilling, thereby improving the quality of the workpiece drilling.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-4 A drilling fixture includes a base 1, a fixing mechanism on the top of the base 1, the base 1 can be fixed to a predetermined position by bolts, and a clamping mechanism is provided on the outside of the base 1.

[0023] Specifically, the fixing mechanism includes a spiral disk 114, a spiral seat 115, a connecting block 116, a guide rod 117, and a clamping plate 118. The spiral disk 114 is rotatably connected to the outer surface of the base 1 via bearings. The spiral seat 115 is slidably connected to the slide rail on the top of the spiral disk 114. Four sets of spiral seats 115 are located on the top of the spiral disk 114 in a rectangular arrangement. The two ends of the connecting block 116 are welded to the bottom of the spiral seat 115 and one end of the guide rod 117. The clamping plate 118 is fixedly connected to the other end of the guide rod 117 by bolts. A support plate 111 is welded to the outside of the base 1. A drive motor 112 is installed at the bottom of the support plate 111. A gear 113 is fixedly connected to the output end of the drive motor 112. The gear 113 meshes with the spiral disk 114.

[0024] With the above technical solution, when the workpiece is placed on the top of the base 1, the drive motor 112 is started, the drive motor 112 drives the gear 113 to rotate, and when the gear 113 rotates, it drives the spiral disk 114 to rotate on the outside of the base 1.

[0025] When the spiral disk 114 rotates, it can drive the spiral seat 115 to move inward or outward. When the spiral seat 115 moves, it drives the guide rod 117 and clamping plate 118 to move through the connecting block 116. When the four sets of guide rods 117 and clamping plates 118 move inward, they can clamp the workpiece around its perimeter, thereby fixing the workpiece and allowing it to be drilled stably without deviation, thus improving the drilling accuracy of the workpiece.

[0026] Specifically, the outer surface of the guide rod 117 is provided with a protrusion, and a fixing block 119 is slidably connected to the outer surface of the guide rod 117. The fixing block 119 is welded to the top of the base 1.

[0027] With the above technical solution, the guide rod 117 slides inside the fixed block 119. The guide rod 117 can be guided by the protrusion so that the guide rod 117 will not deviate when moving.

[0028] Specifically, the clamping mechanism includes a support base 211, a second drive motor 212, and a pressure plate 213. The support base 211 is welded to the outer surface of the base 1. The second drive motor 212 is installed on the outside of the support base 211. One end of the inner rod of the pressure plate 213 is fixedly connected to the output end of the second drive motor 212, and the other end of the inner rod of the pressure plate 213 is rotatably connected to the inside of the support base 211. The pressure plate 213 is a U-shaped plate.

[0029] With the above technical solution, when the workpiece is placed on the top of the base 1, the second drive motor 212 is started. The second drive motor 212 drives the pressure plate 213 to rotate. By adjusting the angle of the pressure plate 213, when the pressure plate 213 rotates inward, one end of the pressure plate 213 can press against the top of the workpiece, so that the workpiece will not move up and down, causing the workpiece to be drilled with a deviation, thereby improving the quality of the workpiece drilling.

[0030] In use, the spiral seat 115 drives the guide rod 117 and clamping plate 118 to move through the connecting block 116. When the four sets of guide rods 117 and clamping plates 118 move inward, they can clamp the workpiece around its perimeter, thereby fixing the workpiece so that it can be drilled stably and is not easily deviated, thus improving the drilling accuracy of the workpiece.

[0031] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
