Description

Technical Field

[0001] This utility model belongs to the field of drilling fixture technology, and specifically relates to a fixing device for drilling tubular workpieces. Background Technology

[0002] Tubular workpieces are common components in the industrial field and are widely used in industries such as machinery, automobiles, petroleum, chemicals, and aerospace. Drilling is a common processing procedure for tubular workpieces, especially in applications such as pipe connections and structural component assembly, where it is often necessary to drill multiple holes precisely on the surface of the pipe.

[0003] Traditional clamps are difficult to ensure the centering and clamping of tubular workpieces, and the drilling position is easily offset due to clamping eccentricity. When machining straight rows of holes, it is necessary to repeatedly tighten and loosen the clamps and reposition them, which is not only inefficient, but also easy to cause hole position deviation. To solve the above problems, we provide a fixing device for drilling tubular workpieces. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for drilling tubular workpieces, so as to solve the problem that traditional clamps mentioned in the background art are difficult to ensure the centering and clamping of tubular workpieces, and the drilling position is easily offset due to clamping eccentricity. When machining straight holes, it is necessary to repeatedly tighten and loosen the clamps and reposition them, which is not only inefficient, but also easy to cause hole position deviation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fixing device for drilling tubular workpieces, including a base, a sliding rod fixedly installed on the top of the base, a sliding sleeve slidably connected to the surface of the sliding rod, and a clamping mechanism provided on the top of the sliding sleeve;

[0006] The clamping mechanism includes a base, the bottom of which is bolted to a sliding sleeve. A bidirectional threaded shaft is rotatably connected inside the base. A threaded sleeve is threadedly connected to the surface of the bidirectional threaded shaft, and a clamping block is fixedly sleeved on the surface of the threaded sleeve.

[0007] Preferably, the surface of the clamping block is provided with a slot, and the surface of the slot is provided with anti-slip texture.

[0008] Preferably, a guide rail is bolted to the top of the base, the bottom of the clamping block is slidably connected to the guide rail, a groove adapted to the guide rail is opened at the bottom of the clamping block, and a handwheel is bolted to one end of the bidirectional threaded shaft.

[0009] Preferably, a limiting sleeve is fixedly connected to the surface of the sliding sleeve, and a limiting bolt is threadedly connected inside the limiting sleeve. One end of the limiting bolt passes through the interior of the sliding sleeve and abuts against the sliding rod.

[0010] Preferably, mounting blocks are bolted to both sides of the base, and the mounting blocks have through holes inside.

[0011] This utility model has the following beneficial effects:

[0012] This device drives the bidirectional threaded shaft to move two clamping blocks in opposite directions along the guide rail by turning the handwheel. The sliding guide between the slide groove and the guide rail ensures clamping alignment. The slots on the inner side of the clamping blocks enable fast and precise clamping of tubular workpieces. The clamped tubular workpieces can be linearly adjusted along the axis of the slide rod. When performing multi-hole machining with a bench drill, there is no need to repeatedly disassemble and assemble the workpiece, which significantly improves drilling position accuracy and machining efficiency, and reduces the labor intensity of the operator. It is particularly suitable for high-precision linear hole machining of tubular workpieces. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example 1:

[0020] refer to Figure 1-4 A fixing device for drilling tubular workpieces includes a base 1, a slide rod 2 fixedly installed on the top of the base 1, a slide sleeve 3 slidably connected to the surface of the slide rod 2, and a clamping mechanism 4 provided on the top of the slide sleeve 3.

[0021] The clamping mechanism 4 includes a base 41, the bottom of which is bolted to a sliding sleeve 3. A bidirectional threaded shaft 42 is rotatably connected inside the base 41. A threaded sleeve 43 is threadedly connected to the surface of the bidirectional threaded shaft 42. A clamping block 44 is fixedly sleeved on the surface of the threaded sleeve 43.

[0022] Specifically, two slide rods 2 are fixedly installed on the top of the base 1, and two clamping mechanisms 4 are provided on the top of the base 1. The interior of the base 41 is rotatably connected to the bidirectional threaded shaft 42 through bearings, and two threaded sleeves 43 are threadedly connected to the surface of the bidirectional threaded shaft 42.

[0023] refer to Figure 4 The clamping block 44 has a slot 45 on its surface, and the slot 45 has anti-slip texture. The slot 45 can effectively fix and clamp the tubular workpiece, and the anti-slip texture can effectively prevent the tubular workpiece from slipping and reinforce it.

[0024] refer to Figure 3 and Figure 4 A guide rail 46 is bolted to the top of the base 41, and the bottom of the clamping block 44 is slidably connected to the guide rail 46. A groove 47 adapted to the guide rail 46 is provided at the bottom of the clamping block 44. By setting the groove 47 and the guide rail 46, the clamping block 44 can be effectively made to slide linearly. A handwheel 48 is bolted to one end of the bidirectional threaded shaft 42. By setting the handwheel 48, the bidirectional threaded shaft 42 can be easily rotated.

[0025] refer to Figure 2 A limiting sleeve 5 is fixedly connected to the surface of the sliding sleeve 3. A limiting bolt 6 is connected to the internal thread of the limiting sleeve 5. One end of the limiting bolt 6 passes through the interior of the sliding sleeve 3 and abuts against the sliding rod 2. By setting the limiting sleeve 5, it can be effectively used in conjunction with the limiting bolt 6. A handle is fixedly connected to one side of the limiting bolt 6, which makes it easy to rotate the limiting bolt 6. By setting the limiting bolt 6, it is easy to limit and fix the sliding sleeve 3.

[0026] refer to Figure 1 Mounting blocks 7 are bolted to both sides of the base 1. The mounting blocks 7 have through holes 8 inside. By setting the through holes 8, the mounting bolts can be effectively matched with the bench drill table for installation.

[0027] Brief description of usage: The user can place the tubular workpiece between the two clamping blocks 44, and then turn the handwheel 48 to drive the bidirectional threaded shaft 42 to rotate. The bidirectional threaded shaft 42 drives the clamping blocks 44 to move in opposite directions through the threaded sleeve 43. At the same time, the clamping blocks 44 slide on the surface of the guide rail 46 through the slide groove 47, so that the clamping blocks 44 clamp the tubular workpiece through the slot 45. The user can use a bench drill to drill holes in the tubular workpiece. At the same time, the user can pull the clamping mechanism 4 to drive the slide sleeve 3 to slide on the surface of the slide rod 2. The user can tighten the limit bolt 6 to limit and fix the slide sleeve 3 through the cooperation of the limit sleeve 5. This can effectively facilitate the linear movement and drilling of the tubular workpiece, thereby avoiding the drilling position deviation caused by repeated disassembly and assembly of the tubular workpiece.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
