Description

Technical Field

[0001] This utility model relates to the field of workpiece fixing technology, specifically to a workpiece clamping and fixing fixture for a bench drill. Background Technology

[0002] A bench drill, also known as a benchtop drilling machine, is a small drilling machine with a vertically arranged spindle, typically mounted on a dedicated worktable. Compared to electric drills, bench drills offer higher drilling accuracy and stability, making them particularly suitable for applications requiring precise drilling. When drilling workpieces using a bench drill, the workpiece needs to be fixed and secured. Existing methods mostly use bolts to fix the workpiece to the surface of the table. However, this is time-consuming and labor-intensive, especially when processing batches of workpieces, requiring frequent removal and removal of the bolts, thus reducing processing efficiency. Therefore, we propose a workpiece clamping and securing fixture for bench drills. Utility Model Content

[0003] The purpose of this utility model is to provide a workpiece clamping and fixing fixture for a bench drill to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a workpiece clamping and fixing fixture for a bench drill includes a fixed base, a connecting part fixedly connected to the side wall of the fixed base, an installation mechanism fixedly assembled inside the fixed base, and an installation shaft passing through the fixed base fixedly connected at the four corners of the installation mechanism. A first fixing member or a second fixing member symmetrically distributed on the left and right is fixedly assembled on the top of the installation shaft. The first fixing member is rectangular, and the opposite side walls of the second fixing member are provided with arc-shaped grooves.

[0005] Preferably, the mounting mechanism includes a fixed tube, which is fixedly connected to the bottom of the mounting base. A telescopic tube is slidably connected to the outer wall of the fixed tube. A telescopic spring is fixedly installed inside the fixed tube. One end of a connecting arm is fixedly connected to the side wall of the telescopic tube, and the other end of the connecting arm is fixedly connected to the side wall of the mounting shaft.

[0006] Preferably, the sidewall of the fixed tube is uniformly provided with limiting grooves, and the inner wall of the telescopic tube is fixedly connected to a limiting block, which is slidably connected within the limiting groove.

[0007] Preferably, a handle block is fixedly connected to the bottom of the telescopic tube.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: A workpiece clamping and fixing fixture for a bench drill, wherein a first fixing member and a second fixing member are assembled by an installation mechanism. The first fixing member and the second fixing member are used to limit and fix rectangular workpieces and circular workpieces, respectively. In use, it is only necessary to place the corresponding workpiece on the surface of the fixing seat, and then the telescopic tube is driven to descend by the telescopic spring, so that the first fixing member or the second fixing member is pressed down to fix the workpiece on the surface of the fixing seat. After the processing is completed, the first fixing member or the second fixing member is moved away from the fixing seat by pressing the telescopic tube upward, so that the workpiece can be easily removed from the fixing seat.

[0009] In actual operation, construction workers do not need to manually make complex adjustments to the first or second fixing component. They can simply press and release the telescopic tube to fix and remove the workpiece, greatly improving work efficiency. At the same time, the symmetrical distribution design of the first and second fixing components ensures the stability of the workpiece during clamping, effectively preventing the workpiece from shifting or shaking during processing and ensuring processing accuracy.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: a workpiece clamping and fixing fixture for a bench drill, including a fixed base 1, a connecting part 2 welded to the side wall of the fixed base 1, the fixed base 1 can be fixedly connected to the bench drill through the connecting part 2, and the height position between the fixed base 1 and the bench drill can be adjusted through the connecting part 2.

[0018] A mounting mechanism 3 is fixedly mounted on the bottom of the mounting base 1. Mounting shafts 4, penetrating the mounting base 1, are fixedly mounted at the four corners of the mounting mechanism 3. The top of the mounting shafts 4 is detachably fixedly mounted with a first fixing member 5 and a second fixing member 6, which are arranged symmetrically. Figure 1 and Figure 2 As shown, the first fixing member 5 is rectangular and is used to clamp and fix the rectangular workpiece from both sides. Its size can be adapted to the size of the workpiece. The opposite side walls of the second fixing member 6 are integrally formed with arc grooves. The second fixing member 6 is used to clamp and fix the circular workpiece.

[0019] like Figure 3 As shown, rubber pads are fixedly connected to the bottom of the first fixing member 5 and the second fixing member 6 respectively. The rubber pads can increase the friction between the first fixing member 5 and the second fixing member 6 and the workpiece, thereby strengthening the fixing effect of the first fixing member 5 and the second fixing member 6 on the workpiece.

[0020] like Figure 3 and Figure 4 As shown, the mounting mechanism 3 includes a fixed tube 31, a telescopic tube 32 slidably connected to the outer wall of the fixed tube 31, a telescopic spring 33 fixedly assembled inside the fixed tube 31 and the telescopic tube 32, one end of a connecting arm 34 welded and fixed to the side wall of the telescopic tube 32, and the other end of the connecting arm 34 welded and fixed to the side wall of the mounting shaft 4. The telescopic spring 33 generates elastic force on the telescopic tube 32, causing the telescopic tube 32 to drive the mounting shaft 4 to move downward through the connecting arm 34, thereby allowing the first fixing member 5 and the second fixing member 6 to fix the workpiece.

[0021] The side wall of the fixed tube 31 is evenly provided with limiting grooves 35, and the inner wall of the telescopic tube 32 is integrally formed with a limiting block 36. The limiting block 36 is slidably connected in the limiting groove 35. Through the cooperation of the limiting block 36 and the limiting groove 35, the telescopic tube 32 is limited along the telescopic stroke of the fixed tube 31, and the stroke stability of the telescopic tube 32 moving along the fixed tube 31 is improved.

[0022] A handle block 37 is welded and fixed to the bottom of the telescopic tube 32. The handle block 37 facilitates pressing the telescopic tube 32 along the fixed tube 31.

[0023] Working principle: such as Figure 5As shown, in the process of using this utility model, the fixed base 1 is connected and fixed to the bench drill through the connecting part 2. According to the shape of the workpiece to be processed in batches, the corresponding first fixing part 5 or second fixing part 6 is selected and connected and fixed to the mounting shaft 4. When it is necessary to fix the workpiece, the handle block 37 is pressed upward to push the telescopic tube 32, so that the mounting shaft 4 drives the first fixing part 5 or second fixing part 6 to move upward. Then, the workpiece is inserted from the side to the bottom of the first fixing part 5 and the second fixing part 6 into the center of the fixed base 1. After releasing the handle block 37, the telescopic tube 32 is driven by the elastic force from the telescopic spring 33 to push the mounting shaft 4 and the first fixing part 5 or second fixing part 6 downward, fixing the workpiece on the surface of the fixed base 1. After processing is completed, the telescopic tube 32 is pushed upward to remove the workpiece. The whole process is simpler and easier to operate, which can improve the processing efficiency when processing workpieces in batches.
