Description

Technical Field

[0001] The invention relates to the field of magnetic drills, in particular to a mini horizontal magnetic drill. Background Art

[0002] A horizontal magnetic drill, also known as a magnetic drill or a magnetic electric drill, is a mobile power tool that uses the electromagnetic principle to adsorb on the surface of steel parts for drilling. Its working principle is to generate magnetism when the electromagnet at the bottom of the machine is energized, and then adsorb on the steel structure to achieve firm fixation.

[0003] The advantage of a general horizontal magnetic drilling rig is that the machine body is relatively low, and it is often used in drilling operations in a narrow space. It can be adsorbed on different positions of the workpiece (such as the horizontal surface, side surface, and top surface) for drilling processing, and is flexible and convenient to use. However, due to its small size, it is generally impossible to set an automatic feed structure, and manual operation is required; At present, the horizontal magnetic drilling rig in the prior art controls the feed through a handle operating lever, and a lifting shaft for controlling the feed is provided on the horizontal magnetic drilling rig, and the openings at both ends of the lifting shaft are respectively located on both sides of the horizontal magnetic drilling rig, and the handle operating lever is connected and matched with the lifting shaft, and the handle operating lever is rotated to drive the lifting shaft to rotate and then drive the drill bit to rise and fall; However, it was found in actual use that the above-mentioned method of controlling the feed requires that there be operating space for installing the handle and rotating the handle on both sides of the horizontal magnetic drill when drilling. When there are raised structures on both sides of the workpiece, the installation and operation processes of the handle will be blocked or restricted. For example, when drilling the middle structure of an "H"-shaped workpiece, if the space between the structures on both sides of the opening of the "H"-shaped workpiece and the horizontal magnetic drill is small, the handle operating rod cannot be smoothly installed on the lifting shaft or the operator cannot smoothly rotate the handle by hand, which affects the drilling work and reduces the practicality of the horizontal magnetic drill.

[0004] Therefore, we made an improvement and proposed the mini horizontal magnetic drill. Summary of the invention

[0005] The purpose of the present invention is to provide operating space for installing a handle and rotating a handle on both sides of the existing horizontal magnetic drill when drilling. When there are raised structures on both sides of the workpiece, the installation and operation processes of the handle will be blocked or restricted, resulting in the handle operating rod being unable to be smoothly installed on the lifting shaft or the operator being unable to smoothly rotate the handle by hand, which affects the drilling work and reduces the practicability of the horizontal magnetic drill.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] Example 1: Reference Figures 1 to 6 , a mini horizontal magnetic drill comprises a body 1, a control system 2 and a motor 3 installed on the side of the body 1, a magnetic base 4 installed on the bottom of the body 1 and electrically connected to the control system 2, and a drilling mechanism installed on the other side of the body 1. A control panel is also provided at the end of the body 1 for controlling the operation of the magnetic base 4 and related electrical components such as the motor 3. The above are some relatively mature technical means for existing horizontal magnetic drills, which will not be described in detail here; The present application mainly solves the problem that when drilling with a horizontal magnetic base drill in the prior art, it is necessary to leave operating space for installing a handle 17 and rotating a handle 17 on both sides of the horizontal magnetic base drill. When there are raised structures on both sides of the workpiece, the operating rod of the handle 17 cannot be smoothly installed with the lifting shaft or the operator cannot smoothly rotate the handle 17 by hand, which affects the drilling work and reduces the practicality of the horizontal magnetic base drill. Therefore, the drilling mechanism of the horizontal magnetic base drill is improved, and the specific drilling mechanism includes: The main shaft 5 installed in the end of the machine body 1 is rotated, and the main shaft 5 is driven by the motor 3 through the transmission module. The lifting sleeve 6 installed in the end of the machine body 1 is slidably installed. The lifting sleeve 6 slides along the axial direction of the main shaft 5, and the drill seat 7 installed at the bottom of the lifting sleeve 6 is rotated. The drill seat 7 is used to install a drill bit for drilling. The top of the drill seat 7 has a spline shaft, and the bottom of the main shaft 5 has a spline sleeve 9 adapted to the spline shaft. The main shaft 5 is driven to rotate by the motor 3. By utilizing the matching relationship between the spline shaft and the spline sleeve 9, the main shaft 5 can drive the drill seat 7 to rotate, and the lifting sleeve 6 can drive the drill seat 7 to rise and fall; It also includes a lifting seat 10 movably installed in the end of the body 1 and located on one side of the lifting sleeve 6. The lifting seat 10 is clamped with the opposite end of the lifting sleeve 6. The lifting seat 10 is driven by a threaded rod 11 installed on the body 1 to slide along the axial direction of the main shaft 5, and a first driven shaft 12 rotatably installed in the middle of the body 1. A lifting gear 13 is installed in the middle of the first driven shaft 12. The side of the lifting sleeve 6 has an arc-shaped gear set 601 meshing with the lifting gear 13. By means of the first driven shaft 12, the lifting gear 13 and the arc-shaped gear set 601 on the side of the lifting sleeve 6, the lifting sleeve 6 can be driven to descend and ascend with the drill bit seat 7 correspondingly by driving the first driven shaft 12 forward and reversely, thereby realizing the operation mode of rotating operation to control the feed in the vertical plane; by means of the threaded rod 11 and the lifting seat 10, the lifting seat 10 is engaged with the lifting sleeve 6, and the lifting seat 10 can be driven to make reciprocating linear motion with the lifting sleeve 6 on the threaded rod 11 by means of the forward and reverse rotation of the threaded rod 11, thereby controlling the corresponding descent and ascent of the lifting sleeve 6 with the drill bit seat 7, thereby realizing the operation mode of rotating operation to control the feed in the horizontal plane; by the combination of the above structures, when drilling a workpiece, the corresponding operation mode can be flexibly selected to improve the operation range of the horizontal magnetic base drilling rig, thereby avoiding the drilling work from being unable to proceed smoothly when the operation space on the side of the horizontal magnetic base drilling rig is limited; It should be noted that, of the two structures for controlling the lifting and lowering of the lifting sleeve 6 (i.e., the drill bit seat 7) provided above, in actual operation, only one group of structures needs to be controlled to drive the lifting and lowering of the lifting sleeve 6, and the other group of structures will not limit the operation of this group of structures. For example, in the process of driving the first driven shaft 12 to rotate, the lifting and lowering sleeve 6 is driven to rise and fall through the cooperation relationship between the lifting gear 13 and the arc-shaped gear set 601. Since the lifting and lowering sleeve 6 is engaged with the lifting seat 10 and the threaded rod 11 is not used, the lifting seat 10 will rotate with the lifting and lowering of the lifting sleeve 6, so that the feed operation proceeds smoothly. Similarly, driving the threaded rod 11 to rotate will drive the first driven shaft 12 to rotate.

[0023] Further, see Figures 1 to 3The machine body 1 includes a first shell 101, in which the control system 2 and the motor 3 are integrated and installed, and the bottom of the first shell 101 has a step surface 1011; and a second shell 102, the bottom of one end of the second shell 102 has a first protrusion 1021 adapted to the step surface 1011, the drilling mechanism is installed in the second shell 102, and the first protrusion 1021 has an axial hole through which the output shaft of the power supply machine 3 passes; and a connecting part 103, which is arranged at the bottom of the first shell 101, and the two sides of the top of the connecting part 103 have covers on the first shell 101 and a connecting plate 1031 of the second shell 102, the magnetic base 4 is fixedly installed at the bottom of the connecting part 103, and the connections between the first shell 101, the second shell 102 and the connecting part 103 are all detachably installed through fasteners (bolts), and correspondingly, corresponding holes (not numbered in the figure) are opened on the first shell 101, the second shell 102 and the connecting part 103 at the connection between each other; through the cooperation of the above structure, the horizontal magnetic base drilling rig is modularly designed, which is convenient for centralized production and assembly, as well as convenient disassembly and replacement of damaged structures.

[0024] Further, see Figures 1 to 3 The top of the second shell 102 has an installation cavity 1022 and an installation cover adapted thereto. The transmission module includes a transmission shaft 14 vertically installed on one side of the installation cavity 1022. The bottom end of the transmission shaft 14 is located at the first protrusion 1021 and is transmission-connected to the output end of the motor 3 through the first gear set 15. The top end of the transmission shaft 14 is transmission-connected to the end of the spindle 5 through the second gear set 16 installed in the installation cavity 1022. Preferably, the motor 3 is vertically installed in the first shell 101, and the output shaft of the motor 3 is transmitted to the spindle 5 through the first gear set 15, the transmission shaft 14, and the second gear set 16, thereby reducing the overall height of the horizontal magnetic base drilling rig, and the structure is short and compact, which reduces the limitation of being unable to operate due to the small space in the working area.

[0025] Further, see Figures 1 to 3The installation cavity 1022 also has an adjustment cavity 1023 for installing the lifting sleeve 6. Both ends of the adjustment cavity 1023 are open. The middle part of the second shell 102 has a tubular installation portion 1024 for horizontally penetrating the first driven shaft 12. Both sides of the adjustment cavity 1023 are respectively provided with movable notches 1025 that are connected to the tubular installation portion 1024 and provide linear reciprocating motion for the lifting seat 10. The above-mentioned structure is arranged to facilitate the installation of each structure. Specifically, during installation, the spindle 5, the lifting sleeve 6, and the drill bit can be first installed. The seat 7 and other structures are placed vertically in the adjusting cavity 1023, and then the first driven shaft 12 is horizontally inserted into the tubular mounting portion 1024, so that the lifting gear 13 on the first driven shaft 12 is horizontally inserted into the arc-shaped tooth group 601 to mesh with it, so as to limit the lifting sleeve 6. It should be noted that the above is only a rough installation process. During the specific installation, if the first driven shaft 12 needs to be fixed to the tubular mounting portion 1024 by a bearing to ensure its rotation stability, etc., it is an existing mature technical means and will not be introduced in detail here.

[0026] Further, see Figure 1 to Figure 2 , and also includes a handle 17 for driving the first driven shaft 12 and the threaded rod 11 to rotate respectively. The two ends of the first driven shaft 12 are respectively provided with first driven grooves 1201 adapted to be engaged with the handle 17. A second driven shaft 18 is installed on the body 1 at the top of the threaded rod 11. The top end of the second driven shaft 18 protrudes from the second shell 102 and is provided with a second driven groove 1801 adapted to be engaged with the handle 17. The end of the handle 17 has an insert block adapted to the first driven groove 1201 and the second driven groove 1801. By plugging the insert block into the first driven groove 1201 or the second driven groove 1801, the handle 17 is rotated, and the lifting process of the lifting sleeve 6 can be driven accordingly.

[0027] Example 2: Reference Figures 1 to 7 This embodiment is a further optimization of the embodiment 1, and provides a solution to the problem in the embodiment 1 that when the lifting sleeve 6 lifts the drill seat 7, the first driven rod and the threaded rod 11 will rotate synchronously, resulting in a large friction force and thus a large force required to rotate the handle 17; Specifically, the outer end of the second shell 102 has a second protrusion 1026, and the adjusting gear 19 is installed on the second protrusion 1026 through a limiting structure. The side wall of the lifting sleeve 6 has a vertical adjusting tooth group 602, and the adjusting gear 19 passes through the corresponding first connecting notch and meshes with the vertical tooth group, and the vertical tooth group and the adjusting gear 19 slide relative to each other in the vertical direction, wherein one end of the arc-shaped tooth group 601 located at the top of the lifting sleeve 6 extends along the periphery of the lifting sleeve 6 to the lifting seat 10, and the end of the lifting seat 10 has a clamping block 1001 that matches the tooth groove in the arc-shaped tooth group 601, and the clamping block 1001 slides relative to the tooth groove of the arc-shaped tooth group 601, and when the clamping block 1001 is engaged with the tooth groove, the lifting gear 13 is separated from the arc-shaped tooth group 601; Among them, the lifting gear 13 and the adjusting gear 19 are both spur gears. By driving the adjusting gear 19 to rotate, the lifting sleeve 6 is driven to rotate, so that when the arc-shaped tooth group 601 is engaged with the block 1001, the teeth on the lifting gear 13 will separate from the arc-shaped tooth group 601 in the horizontal direction, and then when the threaded rod 11 is driven to rotate and the lifting sleeve 6 is driven to rise and fall through the block 1001, the arc-shaped tooth group 601 is not hindered by the lifting gear 13, and correspondingly, is no longer subject to the friction force of the rotation of the first transmission shaft 14; on the contrary, when the lifting gear 13 is engaged with the arc-shaped tooth group 601, the block 1001 is separated from the arc-shaped tooth group 601 (such as Figure 7 As shown in ), when the first transmission shaft 14 is driven to rotate, the block 1001 is not affected by the lifting sleeve 6, so that in the feed mode of the operation, it is not affected by the friction of the threaded rod 11 rotating. Through the cooperation of the above structure, the lifting and lowering operation of the lifting sleeve 6 is more labor-saving, and the practicality of the drilling rig is further improved; it can be understood that the cooperation between the block 1001 and the lifting gear 13 and the arc-shaped gear set 601 can be switched at a fixed position to ensure the smooth rotation of the lifting sleeve 6. At the same time, the block 1001 and the lifting gear 13 always maintain a connection with the arc-shaped gear set 601 to ensure the stability of the lifting sleeve 6; Furthermore, through the above-mentioned setting of the adjusting gear 19 and the adjusting tooth group 602, it can be known from the installation method between the spur gear and the adjusting tooth group 602 that the teeth on the adjusting gear 19 and the adjusting tooth group 602 can slide relative to each other. Therefore, in the limited state, the fixed position adjusting gear 19 will guide the adjusting tooth group 602, that is, to ensure the stability of the lifting and lowering of the lifting sleeve 6.

[0028] Further, such as Figure 2 and Figure 5As shown in the figure, the bottom end of the adjusting gear 19 has an adjusting shaft 1901, the adjusting shaft 1901 is rotatably mounted on the second protrusion 1026 and the bottom end extends out of the second protrusion 1026, and the bottom end of the adjusting shaft 1901 is provided with a third driven groove 1902 adapted to be engaged with the handle 17. Through the arranged adjusting shaft 1901, the handle 17 can be used to drive the corresponding self-adhesive of the adjusting gear 19, thereby adjusting the matching relationship between the arc-shaped tooth group 601 and the lifting gear 13 or the card block 1001. At the same time, the third driven groove 1902 is located at the bottom of one end of the second shell 102, which reduces the probability of accidental touch and further improves the practicality of the device. Practicality; wherein, the limiting structure includes a threaded barrel 20 embedded in the side of the second protrusion 1026 and a threaded column 2001 threadedly engaged with the threaded barrel 20, the inner end of the threaded barrel 20 is connected to the shaft groove on the second protrusion 1026 for the adjusting shaft 1901 to pass through, and a pair of positioning holes 1903 corresponding to the rotation of the lifting sleeve 6 are opened on the adjusting shaft 1901, and the inner end of the threaded rod 11 is adapted to be plugged in with the positioning holes 1903. Through the plug-in relationship between the threaded rod 11 and the adjusting shaft 1901, the purpose of fixing the adjusting gear 19 is achieved, so that the guidance of the lifting sleeve 6 is more stable, thereby ensuring the smooth progress of the drilling work.

[0029] Further, such as Figure 3 and Figure 5 As shown in , the second protrusion 1026 has two ends that are parallelly arranged at the corresponding movable notches 1025, a connecting frame 21 is adapted to be installed between the two second protrusions 1026, and both ends of the connecting frame 21 have fixing plates corresponding to the second protrusions 1026, the threaded rod 11 is installed between the two fixing plates, the lifting seat 10 is threadedly installed on the threaded rod 11 and the inner end is slidably connected to the inner wall of the connecting frame 21, and the top fixing plate of the connecting frame 21 and the corresponding second protrusion 1026 are provided with connecting holes for connecting the second driven shaft 18 and the threaded rod 11, through the setting of the connecting frame 21, the threaded rod 11 is arranged on the connecting frame 21, and can be directly installed on the two second protrusions 1026, so that the installation and cooperation between the adjusting gear 19 and the adjusting tooth group 602 and the installation and cooperation between the block 1001 and the arc tooth group 601 are more convenient; Among them, the outer side of the top end of the second shell body 102 has an installation groove 1027 for installing the second driven shaft 18, the bottom end of the second driven shaft 18 has a second spline shaft 1802, and a spline groove 1101 is correspondingly opened on the threaded rod 11. The second spline shaft 1802 passes through the connecting hole and is inserted into the spline groove 1101. The mounting cover has a limiting ring adapted to the top of the second driven shaft 18. By plugging the second driven shaft 18 and the threaded rod 11, the connecting frame 21 can be installed between the two second protrusions 1026. At the same time, the handle 17 can drive the second driven shaft 18 and the threaded rod 11 to rotate, thereby achieving the purpose of controlling the lifting sleeve 6.
