Description

Technical Field

[0001] This utility model relates to the field of bench drill technology, specifically a bench drill with a dual-guide mechanism. Background Technology

[0002] A drilling machine is a machine tool that mainly uses a drill bit to process holes in a workpiece. Usually, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. It can drill through holes and blind holes, and can perform processes such as reaming, countersinking, boring, or tapping. In the existing technology, most bench drills require a guide structure to hold the workpiece during processing to ensure its stability during the processing.

[0003] The existing patent (authorization announcement number: CN 220278321 U) discloses a bench drill with a dual-guide mechanism. By starting the first motor, the second support member is rotated. In conjunction with the first adjustment component, four sets of first clamping blocks are driven to fix the workpiece. When symmetrical guidance is required, the workpiece is placed on the first clamping block, and then the first motor is started. In conjunction with the second adjustment component, two sets of second clamping blocks are driven to clamp and fix the workpiece.

[0004] However, the above technical solution still has certain defects. The four sets of sliding grooves on the upper surface of the first support member will cause the debris generated during drilling to enter, thereby obstructing the movement of the clamping block and even making it impossible to continue to complete the purpose of clamping the part to be processed. Therefore, a bench drill with a dual guiding mechanism is proposed. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A bench drill with a dual-guide mechanism, such as Figures 1 to 5 As shown, the machine includes a machining table 100, a support leg 120 welded to the bottom of the machining table 100, a protective component 110 mounted on the front surface of the support leg 120, and a bench drill body 160 mounted on the top of the machining table 100.

[0026] The rear surface and left side wall of the processing table 100 are provided with stroke grooves 104. Each set of stroke grooves 104 is equipped with a drive motor 101 on the inner wall. The output end of the drive motor 101 is provided with a bidirectional lead screw 102 that is rotatably arranged with the inner wall of the stroke groove 104. Two sets of L arms 103 are threaded on the outer wall of the bidirectional lead screw 102. The two sets of L arms 103 extend to the upper surface of the processing table 100.

[0027] The protective assembly 110 includes two sets of electric push rods 112 fixed to the front surface of the support leg 120. A baffle 111 is provided between the two sets of electric push rods 112. The output end of the electric push rod 112 is fixed to the side wall of the baffle 111. The middle part of the baffle 111 is a transparent acrylic plate.

[0028] First, place the workpiece to be processed on the processing table 100, and control the two sets of drive motors 101 to operate. Their output ends will drive the bidirectional lead screw 102 to rotate, so that the two sets of L arms 103 on its outer wall are brought closer to each other until they contact the workpiece to complete the fixation in one direction. At the same time, the other set of drive motors 101 makes the L arms 103 contact the outer wall of the workpiece in the other direction, and finally complete the fixation of the workpiece. This method can be used to fix different types of workpieces. Then, control the drill body 160 to drill holes in the tool.

[0029] Before drilling the workpiece, the output end of the electric push rod 112 can be raised, which will cause the baffle 111 to rise and form a protective wall between the worker and the processing table 100, preventing the flying debris generated during drilling from injuring people. This can improve the safety factor of the device.

[0030] Please refer to this carefully. Figure 1 and Figure 2 A horizontal arm 170 is provided through the body of the bench drill 160. One end of the horizontal arm 170 is movably sleeved with a column 140 fixed to the top of the processing table 100. A lead screw 150 is provided on one side of the column 140 and rotates longitudinally. Support plates are fixed at both ends of the column 140. The lead screw 150 passes through the horizontal arm 170 and is rotatably connected to two sets of support plates. A motor 151 connected to the end of the lead screw 150 is installed on the top support plate.

[0031] The output of motor 151 drives lead screw 150 to rotate, which enables cross arm 170 to drive bench drill body 160 to rise and fall, completing the drilling operation on the workpiece. At the same time, bench drill body 160 moves and locks on the outer wall of cross arm 170, realizing drilling operations at multiple positions on the workpiece.

[0032] Please refer to this carefully. Figure 1 and Figure 2 The top of the processing table 100 is located on one side of the column 140 and a storage box 130 is provided. Multiple drawers are movable on the outer wall of the storage box 130.

[0033] It can store different types of drill bits and the tools used to assemble and disassemble drill bits, thereby improving the efficiency of the device during maintenance.

[0034] Please refer to this carefully. Figure 1 and Figure 2 The top of the processing table 100 is located on the other side of the column 140 and has a control panel. The control panel is connected to the motor 151 and the protective component 110 by wires.

[0035] The control panel makes raising the protective assembly 110 and lowering the cross arm 170 more efficient, making the drilling of workpieces safer and more efficient.

[0036] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The top of the processing table 100 is provided with a U-bar 105 at the end of the L-arm 103 away from the bidirectional lead screw 102. The U-bar 105 is sleeved on the end of the L-arm 103 and fixed to the top of the processing table 100.

[0037] The ends of the L-arm 103 are fiberd using U-strip 105 to prevent them from curling up and affecting the clamping effect on the workpiece.

[0038] In use, first place the workpiece to be processed on the processing table 100, and control the two sets of drive motors 101 to operate. Their output ends will drive the bidirectional lead screw 102 to rotate, so that the two sets of L arms 103 on its outer wall are brought closer to each other until they contact the workpiece to complete the fixation in one direction. At the same time, the other set of drive motors 101 makes the L arms 103 contact the outer wall of the workpiece in the other direction, and finally completes the purpose of fixing the workpiece. It can be used to fix different types of workpieces. Then, control the drill body 160 to drill holes in the tool.

[0039] Before drilling the workpiece, the output end of the electric push rod 112 can be raised, which will cause the baffle 111 to rise and form a protective wall between the worker and the processing table 100, preventing the flying debris generated during drilling from injuring people. This can improve the safety factor of the device. All parts not involved in the device are the same as or can be implemented using existing technology.
