DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0024] Example

[0025] In view of the current problem that in the process of making accessories by factory machine repair personnel, since most accessories need to be made on-site according to actual conditions, the equipment used for drilling operations is mostly portable. Therefore, when drilling materials, they can only do the work by hand, resulting in low drilling accuracy and high requirements for the work experience and ability of maintenance personnel. We propose an auxiliary drilling platform with a simple and compact structure, easy to carry, and capable of being used in conjunction with an electric hand drill. This reduces the requirements for technical proficiency of technicians and improves drilling accuracy, allowing unskilled maintenance personnel to achieve high precision and quickly perform drilling operations. The specific solution is as follows:

[0026] like Figure 1-4 As shown, this embodiment provides an electric hand drill auxiliary drilling platform, including a base 1, a column 2, a material lifting platform, an operating unit and a hand drill fixing assembly 13; wherein, the column 2 is vertically welded to one side of the base 1 as the main installation support structure of each unit, and at the same time, in order to improve the stability of the entire drilling platform, its base 1 adopts an I-shaped design.

[0027] The material lifting platform is adjustably mounted on the surface of the column 2, and the material lifting platform is horizontally arranged; in order to achieve the adjustment of the upper and lower positions of the material lifting platform on the surface of the column 2, the material lifting platform specifically includes a sleeve 3 movably sleeved on the outside of the column 2, and a support frame 4 horizontally welded to one side of the sleeve 3, a loading platform 6 is fixed on the top of the support frame 4, a slot 7 is provided in the center of the loading platform 6, and an adjusting knob 5 is also provided on the sleeve 3. The front end of the adjusting knob 5 passes through the sleeve 3 and contacts the surface of the column 2. By twisting the adjusting knob 5 and with the help of the threaded fit between the adjusting knob 5 and the sleeve 3, the position of the sleeve 3 on the column 2 can be adjusted, thereby achieving the upper and lower position adjustment of the entire material lifting platform on the column 2.

[0028] The operating unit includes a lever mechanism and a sliding assembly. The lever mechanism is installed at the top of the column 2, and the sliding assembly is installed near the upper end of the column 2. The lever mechanism and the sliding assembly cooperate with each other; and the hand drill fixing assembly 13 is horizontally fixed on the sliding assembly in the operating unit.

[0029] In order to achieve the coordination between the material lifting platform and the operating unit, and also to prevent the hand drill fixing assembly 13 and the material lifting platform from generating horizontal angular deviation during the movement process, the base 1 and the column 2 are both made of square tubes, so that the operating unit drives the hand drill fixing assembly 13 to move up and down only on the column 2, and the material lifting platform is designed on the same side as the operating unit and the hand drill fixing assembly 13.

[0030] The operator presses the sliding assembly downward by pressing the lever mechanism, thereby driving the electric hand drill fixed in the hand drill fixing assembly 13 to move vertically downward, and finally realizes vertical drilling of the material in cooperation with the material lifting platform.

[0031] In order to realize vertical up and down movement of the hand drill fixing assembly 13 under the drive of the operating unit, its sliding assembly includes a bottom support 9 and a top support 10 respectively fixed at the middle and top of the column 2, the bottom support 9 and the top support 10 are on the same side, and a limiting column 11 parallel to the column 2 is fixed between the bottom support 9 and the top support 10, and a sliding sleeve 12 is provided between the bottom support 9 and the top support 10, which is slidably connected with the limiting column 11 and the column 2 respectively, and a pin pile 17 designed to be at a vertical angle to the hand drill fixing assembly 13 is horizontally fixed on the side of the sliding sleeve 12. Through the cooperation of the limiting column 11 and the column 2, double-rod positioning is realized, so that the sliding sleeve 12 can only slide in the direction of the column 2 and the limiting column 11.

[0032] In order to realize the linkage between the lever mechanism and the sliding assembly, so that the operator can drive the sliding assembly to move vertically through the lever mechanism, and finally realize the drilling processing of the material, the lever mechanism includes a vertical frame 14 installed on the top of the top support 10, and an operating handle 16 is rotatably installed on one side of the top of the frame 14 through a rotating shaft 15. The operating handle 16 is connected to the pin pile 17 on the sliding sleeve 12 through a bolt near the middle position with a lower pressure arm 18. The two ends of the lower pressure arm 18 are all designed to be rotatably connected to the pin pile 17 and the operating handle 16. The rotating shaft 15 and the sliding sleeve A tension spring 19 is connected between the pin piles 17 on 12, and the lower pressure arm 18 is designed with an inclined angle. In this design, the operating handle 16 is linked with the sliding assembly through the lower pressure arm 18. The operator presses down the operating handle 16, so that the lower pressure arm 18 moves downward, pushing the sliding sleeve 12 in the sliding assembly to move downward along the column 2 and the limit column 11, thereby causing the hand drill fixing assembly 13 to move downward. During this process, the tension spring 19 is stretched. When the drilling is completed, the sliding sleeve 12 moves up and resets under the action of the tension spring 19, and pushes the lower pressure arm 18 up to force the operating handle 16 to reset.

[0033] In order to improve the on-the-spot adaptability of the drilling platform during operation, its hand drill fixing assembly 13 includes a square main body 131 horizontally fixedly installed on the outside of the sliding sleeve 12, and an extension arm 132 is slidably inserted into the main body 131. This design can ensure that the extension arm 132 maintains the angle of the electric hand drill fixed at the front end unchanged during the telescopic adjustment process. Moreover, in order to achieve adjustable drilling position, a long strip of through-hole is opened on the main body 131, and an adjusting bolt B133 is provided at the tail end of the extension arm 132 corresponding to the through-hole position, and a scale B134 is also provided on the surface of the extension arm 132.

[0034] In order to fix the electric hand drill, a semicircular clamp ring 135 is hinged on both sides of the front end of the extension arm 132. The two clamp rings 135 are designed to be opposite to each other, and a rubber pad 136 is fixed on the inner side of each clamp ring 135. The front end of the clamp ring 135 is locked by a fastening bolt 137.

[0035] In order to adapt to the adjustable effect of the hand drill fixing assembly 13, the slot hole 7 on its loading platform 6 is designed to be long and narrow along the extension direction of the extension arm 132, and the slot hole 7 and the center position of the clamp ring 135 are designed to correspond to each other in the upper and lower positions.

[0036] In order to facilitate batch processing of accessories of the same specifications, shorten the positioning time of each accessory processing material, and improve the accuracy of part drilling, the support frame 4 is welded with galvanized square tubes, and the front end of the support frame 4 is a "П"-shaped structure. At the same time, auxiliary positioning units 8 are also installed on the square tube frames on both sides of the front end of the support frame 4. The auxiliary positioning units 8 include long strip avoidance slots 801 opened on the outside and bottom of the frames on both sides of the front end of the support frame 4, and two groups of cursor units designed relatively and slidably installed on the inside of the front end frame of the support frame 4. The cursor unit includes a slider 802 slidably installed on the inside of the front end frame of the support frame 4. An L-shaped positioning ruler 803 is fixed on the side of the slider 802. The positioning ruler 803 extends to the outside of the worktable 6 through the avoidance slot 801 on the side of the support frame 4. An adjusting bolt A804 is installed on the bottom of the slider 802 corresponding to the avoidance slot 801 at the bottom of the support frame 4. A ruler A805 is also provided on both sides of the worktable 6.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
