Technical Field

[0001] The invention relates to the technical field of bench drills, in particular to a stepless speed-regulating bench drill with a self-locking function. Background Art

[0002] The full name of bench drill is bench drilling machine, which is a machine tool used for drilling and tapping. It is small in size and easy to operate. It is widely used in manufacturing, mechanical processing, electronic manufacturing, instrumentation and other industries. After searching, in the patent document with publication number CN214054426U, a bench drill with a self-locking positioning mechanism is disclosed. The invention can prevent the material from shifting during cutting by positioning the positioning component on one end of the material and the operator pressing on the other end of the material, which not only improves the accuracy of drilling, but also saves the operator's work effort. However, when the above invention is used, since there is no corresponding shielding structure at the position facing the bench drill, the staff is easily splashed by the debris generated by the drilling of the workpiece during the operation of the bench drill, which poses certain safety hazards. Therefore, it is necessary to propose a stepless speed-adjustable bench drill with a self-locking function. Summary of the invention

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1:

[0018] See also Figure 1The full name of bench drill is bench drilling machine, which is a machine tool for drilling and tapping. It is small in size and easy to operate. It is widely used in manufacturing, mechanical processing, electronic manufacturing, instrumentation and other industries. The present invention provides a technical solution: a stepless speed regulation bench drill with a self-locking function, comprising a base 1, and foot pads 7 are installed at the four corners of the bottom of the base 1. The foot pads 7 are set to anti-slip foot pads, and the anti-slip foot pads 7 make the placement of the base 1 more stable.

[0019] In this embodiment, please refer to Figure 1 and Figure 2 A bench drill body 2 is installed on the top right side of the base 1. The bench drill body 2 is a common existing technology and can perform stepless speed regulation. A positioning component 3 is arranged on the top middle side of the base 1. The positioning component 3 includes a slide groove 31. The slide groove 31 is opened on the top middle side of the base 1. A bidirectional screw rod 32 is installed in the groove of the slide groove 31. Positioning clamping plates 33 are threaded on both sides of the outer wall of the bidirectional screw rod 32. One end of the bidirectional screw rod 32 passes through the base 1 and is installed with a knob 34. By placing the workpiece to be drilled on the top of the base 1, the bidirectional screw rod 32 is driven to rotate by turning the knob 34, and then the two positioning clamping plates 33 are driven to clamp the workpiece along the slide groove 31 to achieve the purpose of positioning and fixing, and avoid the workpiece from being offset during drilling.

[0020] In this embodiment, please refer to Figure 1 and Figure 3 The two support plates 4 are symmetrically installed on the left side of the top of the base 1. The two support plates 4 are respectively located on both sides of the positioning assembly 3. Slide rails 5 are installed on the top of the two support plates 4. A shielding assembly 6 is arranged between the two slide rails 5. The shielding assembly 6 includes a baffle 61. Threaded columns 62 are installed on both sides of the end of the baffle 61. Fastening nuts 63 are arranged on the ends of the threaded columns 62. The size of the threaded columns 62 is adapted to the size of the slide rail 5. The end of the threaded column 62 away from the baffle 61 passes through the slide rail 5 and is threadedly connected with the fastening nut 63. One side of the fastening nut 63 is in close contact with the surface of the slide rail 5. Before clamping the workpiece, the baffle 61 is moved to the left along the slide rail 5 so that the threaded column 62 moves to the leftmost side of the slide rail 5. Then the baffle 61 is turned ninety degrees and the position of the baffle 61 is fixed by the fastening nut 63. This can form a shielding structure on the front of the bench drill body 2. The baffle can block the debris generated by drilling the workpiece, thereby preventing the debris from splashing onto the staff and reducing safety hazards.

[0021] In this embodiment, please refer to Figure 3 A transparent window 64 is provided on the surface of the baffle 61. The transparent window 64 can block debris while facilitating staff to observe through the baffle.

[0022] Embodiment 2:

[0023] See also Figure 2 This embodiment is different from the first embodiment in that: anti-skid pads are provided on the sides of the two positioning clamps 33 that are close to each other, and the surfaces of the anti-skid pads are provided with anti-skid patterns. The anti-skid pads can increase the friction between the workpiece and the workpiece, so that the fixing effect of the workpiece is better.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
