Drilling device with adjustable positioning dimensions and support pressing and clamping

Abstract

On this drilling device, it can be adjusted to the corresponding horizontal and vertical position dimensions for drilling and then fixed. The drilling position dimensions are determined by the relative horizontal and vertical position dimensions represented by the perpendicular distances from the center point of the starting point hole template bushing to the right-angle elbow surface of the telescopic scale and the reference backing surface respectively; the position dimensions of the entire adjusted and fixed drilling device are obtained by leaning and pressing on the corresponding adjacent edges of the processing board surface to get the drilling position, and then the position dimensions on the processing board are clamped and locked with a large pliers before drilling; the process of drawing marking lines is omitted. During the drilling process, the movement and deviation of the drilling position dimensions are prevented. Due to the combined characteristics of the clamped and fixed drilling device position dimensions and the guiding length of the bushing, the drill bit is first inserted into the guiding length of the bushing and then drilling is carried out. By using the drilling device, the process of drawing marking lines is omitted and the requirement for the operation technical difficulty is reduced.

Description

Technical Field

[0001] The invention relates to a drilling device for woodworking production and installation, in particular to a drilling device which can be adjusted to the positioning size of the drilled hole and can be supported, pressed and clamped. Background Art

[0002] Currently, at the processing site of installation and production, the processing board is in different spatial positions in the three-dimensional space. The operator must repeatedly move and adjust the entire body position to the most suitable operating posture, and then draw marking points on the processing board and drill holes of different specifications and diameters. First, the corresponding marking line points of the drilling center points must be drawn. The drilling center points of the processing plate surface are the intersection points or related points of the vertical distance lines to the adjacent edges. The marking line points are drawn with a pen. The work of drawing the marking line points one by one is tedious and large in quantity. Errors and mistakes are often marked due to the distance deviation between the body position and the processing plate surface position. In particular, the marking of multiple hole point positions with related dimensional tolerance requirements between holes is more prone to errors. The next step is to operate the drilling. The operation action is to hold the processing plate surface with one hand to hold it as the operating reference, and use the electric drill tool with the other hand to align the marking line points and drill directly, or press the drilling hole point template against the processing plate surface with one hand as the operating reference, and use the electric drill tool with the other hand to drill the holes on the hole point template. Affected by the limitations and constraints of on-site processing conditions, there are natural errors in the operator's body control of the reference processing plate surface in the spatial position of the drilling, which causes the drilled position size to often slide, run, offset and move during the operation. The influence of forces from several aspects is obvious. :The torque of the electric drill itself during operation and the reaction force generated on the processing board during drilling often cause the drill bit to slide and the drilling point to shift. The action of the drill bit drilling and removing chips multiple times and then continuing to drill again will cause multiple offsets and movement of the size position, resulting in dimensional errors. Or when drilling by holding the hole template to press and support the processing board to form a fixed overall position, the loss of clearance and the continuous pressure of the human hand on the processing board will also cause the hole template to shift and reposition again, which will cause the size position of the drilled hole to shift and change. The tolerance accumulation caused by several factors in the above operation process also leads to large position tolerances or misalignment of the drilled hole. In particular, when multiple hole positions have related dimensional tolerances, the errors and mistakes are more obvious, which often affects the installation and assembly of the workpiece in the subsequent process. The work of marking and drilling at the installation and processing site is tedious and large in quantity. Accurate drilling requires very high conditions on the processing site and the technical requirements of the operator. Errors in marking and drilling points and rework often occur. Summary of the Invention

[0003] The object of the present invention is to provide a drilling device with adjustable positioning dimensions and a clamping and pressing function to solve existing problems; according to the principle of converting three-dimensional coordinates into two-dimensional coordinates, the principle of how to determine the point coordinates in a plane rectangular coordinate system, and based on the compositional relationship that multiple components on the drilling device are parallel and perpendicular to each other, as well as the relationship that the movement between the components of the drilling device is parallel and perpendicular movement to adjust and determine the center point of the drill hole; on this drilling device, after adjusting to the corresponding horizontal position dimension and vertical position dimension of the center point of the drill hole and fixing them, the starting point position dimension of the center point of the drill hole is the center point of the starting point hole template bushing, which is the perpendicular distance to the right-angle elbow surface of the telescopic scale and the perpendicular distance to the reference backing surface respectively; for the position dimensions adjusted and fixed on the drilling device, use the reference backing surface and the right-angle elbow surface of the telescopic scale on the device to simultaneously lean against and press on the corresponding adjacent edges of the processing board surface to obtain the drilling position dimension, and use a large clamp to clamp and lock the position dimension on the processing board surface and then drill, thus saving the process of drawing marked line points on the processing board surface; furthermore, during the drilling process, it prevents the movement and deviation of the drilling position dimension. Through the combination of the fixed position dimension of the drilling device, the position dimension of the bushing of the hole template unit, and the guiding length of the bushing, after the drill bit is directly inserted into the guiding length cavity of the bushing and then drilled, the technical difficulty requirements for the body operation during drilling are reduced and the drilling accuracy is improved by utilizing the accuracy of the drilling device itself; this drilling device is a pair of devices with axial symmetry to meet the drilling requirements for processing board surfaces with axially symmetric position dimensions; and for different specifications of hole template units, there are characteristics such as the center point of the starting point hole template bushing, the position dimension, and the structural composition of the back sliding surface of the hole template being related, enabling interchangeability between different specifications of hole template units and increasing the diversity of hole template unit specifications; through the above technical solutions and methods in several aspects, the problems of drawing marked line points, poor drilling accuracy, and high operation technical difficulty existing in the existing drilling operation are solved, so as to achieve the purpose of improving work efficiency.

[0004] The drilling device with adjustable positioning dimensions and a clamping and pressing function includes an adjustment and positioning clamping unit, a hole template unit, and a quick-release connection and combination fastener. The drilling device is made of metal materials.

[0005] The adjustment and positioning clamping unit and the hole template unit are tightly connected into the entire drilling device by the quick-release connection and combination fastener.

[0006] The adjustment and positioning clamping unit includes an adjustment and clamping reference surface, the lower jaw of the large clamp moving head, a reference backing surface, a large clamp, the upper jaw of the large clamp, a hole template connection backing surface, a through hole and chute, a longitudinal scale surface, a limit backing surface, a transverse scale telescopic scale, a right-angle elbow surface of the telescopic scale, a combination of telescopic scale fasteners, a transverse scale pointer, a through hole of the transverse scale pointer, a line of the transverse scale pointer, and an adjustment through hole.

[0007] The hole template unit includes a hole template reference surface, a starting point hole template bushing, the center point of the starting point hole template bushing, an associated bushing, the center point of the associated bushing, a hole template back sliding surface, a through hole in the hole template back sliding surface, a hole template pointer surface, and a hole template pointer line.

[0008] The reference backing surface is the reference positioning position of the device and the basis for the expansion of the dimension position. The reference backing surface is vertically connected downward to the adjusting and clamping reference surface.

[0009] The adjusting and positioning clamping unit is composed of an adjusting and clamping reference surface which is a rectangular surface. One side of the end line of the rectangular surface is fixedly connected downward with a rectangular reference backing surface and they are perpendicular to each other. The other side of the adjusting and clamping reference surface is fixedly connected upward with a rectangular limiting backing surface and they are perpendicular to each other. The limiting backing surface is parallel to the reference backing surface. On one side end line of the adjusting and clamping reference surface, a rectangular hole template connecting backing surface is fixedly connected upward and they are perpendicular to each other, and at the same time, it is also perpendicular to the reference backing surface and the limiting backing surface. There is a long through hole chute on the hole template connecting backing surface. A rectangular longitudinal scale ruler surface is fixedly connected on the hole template connecting backing surface and they are perpendicular to each other. The longitudinal scale ruler surface is parallel to the adjusting and clamping reference surface and is located on the upper side. There are dimension scales on the longitudinal scale ruler surface.

[0010] The limiting backing surface closely places a rectangular strip-shaped transverse scale telescopic ruler and is pressed and fixed on the adjusting and clamping reference surface by a telescopic ruler fastener combination.

[0011] There are dimension scales on the transverse scale telescopic ruler. The end of the transverse scale telescopic ruler is connected and fastened to the right-angled telescopic ruler right-angle elbow surface to form a right angle. The telescopic ruler right-angle elbow surface is the end surface of the transverse position dimension.

[0012] The transverse scale telescopic ruler closely places on the limiting backing surface for transverse scale adjustment. The movement and fixation of the scale position dimension on the transverse scale telescopic ruler are used to determine the relative transverse scale value pointed by the transverse scale pointer line. The telescopic ruler fastener combination presses and fixes the scale value on the adjusting and clamping reference surface; it is equal to the vertical distance dimension from the center point of the starting point hole template bushing to the telescopic ruler right-angle elbow surface; it is equal to the vertical transverse value from the drilling center point on the processing plate surface to the edge of the corresponding processing plate surface; the end of the transverse scale telescopic ruler is connected and fastened to the right-angled telescopic ruler right-angle elbow surface to form a right angle. The telescopic ruler right-angle elbow surface is the end surface of the transverse position dimension.

[0013] The horizontal scale pointer is a rectangular strip with dimensional scales on it and a long rectangular through-hole on it. The end of the horizontal scale pointer is a horizontal scale pointer line. The horizontal scale pointer is fixed by passing a fastening connecting screw through the through-hole of the horizontal scale pointer and the adjusting through-hole on the limiting backing surface and pressing and connecting them.

[0014] The large pliers are located on one side of the reference backing surface. The upper jaw of the large pliers is fixedly connected to the upper surface of the adjusting clamping reference surface. The lower jaw of the moving head of the large pliers is a moving head, which is located on one side of the lower surface of the adjusting clamping reference surface. The large pliers are fixedly connected to the upper surface of the adjusting clamping reference surface through the upper jaw of the large pliers, and firmly lock the processing board surface by the biting force with the lower jaw of the moving head of the large pliers. After loosening the jaws of the large pliers, the next position dimension can be re-clamped. The large pliers have the characteristic of quick conversion between clamping and loosening. The lower jaw of the moving head of the large pliers is a moving head to prevent scratching the processing board surface. The large pliers clamp the entire drilling device on the processing board surface to prevent the sliding and moving of the position dimension.

[0015] On the respective surfaces of the adjusting clamping reference surface, the reference backing surface, and the limiting backing surface, there are multiple adjusting through-holes, which are used to prevent and eliminate the changes in the thermal deformation of the drilling device, and are used to pass through the connecting screw for adjusting and fastening.

[0016] The starting point hole template bushing of the hole template unit is vertically fixedly connected to the rectangular hole template reference surface. The axis line of the starting point hole template bushing is also perpendicular to the hole template reference surface. The through-hole of the starting point hole template bushing penetrates the hole template reference surface to form a through-hole. On one side of the end line of the hole template reference surface, a rectangular hole template backrest sliding surface is vertically fixedly connected upward. There is a through-hole on the hole template backrest sliding surface. The hole template backrest sliding surface is vertically fixedly connected to a hole template pointer surface. The hole template pointer surface is parallel to the hole template reference surface and extends to the other side. There is a hole template pointer line on the hole template pointer surface.

[0017] The plane formed by the perpendicular line from the center point of the starting point hole template bushing to the hole template backrest sliding surface and the hole template pointer line is perpendicular to the template reference surface.

[0018] There are coupling sleeves on the hole template reference surface. There are multiple of the said coupling sleeves. The multiple said coupling sleeves are spaced apart and distributed on the hole template reference surface and are perpendicular. They are respectively associated and corresponding to the position dimensions from the starting point hole template bushing and the hole template backrest sliding surface. The distances from the center points of the multiple respective coupling sleeves to the center point of the starting point hole template bushing are respectively determined values. The distances from the center points of the multiple respective coupling sleeves to the respective perpendicular points on the hole template reference surface are also respectively determined values. The axis lines between each sleeve are parallel and perpendicular to each other on the hole template reference surface.

[0019] The diameters of the sleeve holes between the starting point hole template bushing and the multiple associated bushings can be the same or different, or they can coincide to form only one starting point hole template bushing. The through holes of the center points of the multiple respective associated bushings penetrate the template reference plane to form through holes.

[0020] The center points of the other multiple associated bushings are only associated respectively with the center point of the starting point hole template bushing and the position dimensions of the template back sliding surface. The center points of the multiple associated bushings are composed of a structural method determined by the center point of the starting point hole template bushing and the position dimensions of the template back sliding surface, forming different specifications of hole template units. This enables interchangeability in the use between different specifications of hole template units, increasing the diversity of the hole template unit specifications of the drilling device, and the precision of the connection of the position dimension relationships between the various components on the hole template unit into a whole.

[0021] The center point of the described starting point hole template bushing corresponds to the corresponding point on the processing board surface on the drilling device, which is the drilling center point of the processing board surface.

[0022] All the bushings have their respective guiding hole lengths of a certain length. For bushings with a sleeve hole diameter of less than 10 mm, the guiding length of the sleeve hole is more than 3 times the diameter, which can ensure the vertical precision of drilling.

[0023] The back sliding surface is pressed against the template pointer surface and moves and is fixed along the position dimensions on the template connecting backing surface and the longitudinal scale surface to determine the scale value pointed to by the template pointer line; and the quick-release connection combination fastener passes through the through-hole chute and the through-hole of the template back sliding surface and is pressed and fastened on the longitudinal scale surface. The scale value of its position dimension is the longitudinal position dimension on the drilling device, equivalent to the vertical distance dimension from the center point of the starting point hole template bushing to the reference backing surface; equivalent to the vertical longitudinal value from the drilling center point on the processing board surface to the corresponding edge of the processing board surface.

[0024] The bottom surfaces of the adjusting clamping reference surface and the hole template reference surface are in the same plane position.

[0025] The transverse value and the longitudinal value of the drilling point on the processing board surface to be drilled corresponding to the edge of the processing board surface are respectively adjusted to correspond to the transverse position dimension and the longitudinal position dimension on the drilling device.

[0026] By using the telescopic scale right-angle elbow surface and the reference backing surface of the drilling device to lean on and press the corresponding edge of the processing board surface for the adjusted position dimensions on the entire drilling device, a simplified operation for obtaining the drilling position dimensions is achieved.

[0027] The position dimensions fixed on the entire drilling device are clamped and fixed on the processing plate surface by a vise to prevent the movement of the dimensional position, and then the drill bit is directly inserted into the guiding length cavities of the respective bushings, which can conveniently and quickly align the position dimensions to be drilled, and drill holes in the respective bushings with fixed position dimensions on the drilling device.

[0028] The device is a pair of drilling devices that are axisymmetric to meet the drilling requirements for axisymmetric position dimensions.

[0029] For those with the same and consistent requirements for drilling position dimensions, the drilling operation is directly repeated using the position dimensions fixed on the drilling device, saving the time of repetitive labor.

[0030] The center point of the starting point hole template bushing of the drilling device corresponds to the corresponding point on the processing plate surface, which is the drilling center point of the processing plate surface, as well as the horizontal and vertical values corresponding to the adjacent edges of the processing plate surface from the drilling center point of the processing plate surface.

[0031] The first step is to first use the horizontal scale pointer line to indicate the center point position of the starting point hole template bushing in the horizontal direction: while fastening it to the limiting backing surface, adjust the horizontal scale pointer line on the movable horizontal scale pointer to be parallel and aligned with the horizontal starting point position on the side of the center point direction of the starting point hole template bushing and fix it. That is, the vertical position dimension distance from the center point of the starting point hole template bushing to the hole template connecting backing surface is equal to the vertical distance dimension value from the center point of the starting point hole template bushing to the hole template back sliding surface.

[0032] The second step is to adjust the relative horizontal position dimension of the drilling device: using the starting point position of the already positioned horizontal scale pointer line, adjust the right-angled elbow surface of the telescopic gauge to the corresponding scale value on the horizontal scale telescopic gauge and fasten it with the telescopic gauge fastener combination, which is equivalent to adjusting the horizontal value of the vertical distance dimension from the drilling center point of the processing plate surface to the corresponding edge of the processing plate surface.

[0033] The third step is to adjust the relative vertical position dimension of the drilling device: that is, adjust the position dimension of the scale value where the hole template pointer line is pressed against the vertical scale gauge surface, which is equivalent to adjusting the vertical position dimension from the center point of the starting point hole template bushing to the reference backing surface, i.e., the vertical value, and is equivalent to adjusting the vertical value of the vertical distance dimension from the drilling center point of the processing plate surface to the corresponding edge of the processing plate surface.

[0034] Through the above steps of operation on the drilling device, the position dimensions to be drilled can be adjusted, eliminating the operation of marking points on the processing plate surface. The position dimensions are directly displayed as scale values on the drilling device on the corresponding scales of the pressure gauge.

[0035] Lock and fasten the horizontal and vertical dimensions of the scale relative to the drilling device. At the same time, obtain all the drilling position dimensions by pressing the right-angle elbow surface of the telescopic scale and the reference backing surface of the entire drilling device against the opposite edge of the processing board surface. Then, use a large clamp to clamp the entire drilling device on the processing board surface and lock it to prevent the sliding and movement of all drilling position dimensions. Pressing and clamping against the processing board surface during operation reduces the operation difficulty, facilitates control, and improves the operation speed.

[0036] For the drilling device locked on the processing board surface by a large clamp, the center point positions of all bushings are fixed with respect to the position of the processing board surface. The drill bit for drilling directly inserts into the guiding length cavity within the bushing and then drills, thereby improving the drilling accuracy by utilizing the accuracy of the hole template unit of the drilling device itself and reducing the technical difficulty requirements for physical operation.

[0037] The beneficial effects of the present invention. The purpose of the present invention is to provide a drilling device with adjustable positioning dimensions and a pressing and clamping function. According to the principle of converting three-dimensional coordinates into two-dimensional coordinates, the principle of how to determine the coordinates of points in a plane rectangular coordinate system, and based on the fact that the various components of the drilling device are parallel and perpendicular to each other, and the movement between the components of the drilling device is a parallel and perpendicular movement relationship to determine the characteristics of the drilling point position. By adjusting the horizontal and vertical positions of the center point of the starting point hole template bushing on the drilling device, the positioning dimensions of the drilling position can be adjusted.

[0038] Marking line points on the processing board surface in a three-dimensional space position are converted into adjustable position dimensions for drilling on the drilling device, thus eliminating the process of marking line points on the processing board surface.

[0039] When drilling on the processing board surface in a three-dimensional space by continuously adjusting the body processing position, the method of drilling at the drilling position by adjusting the body to the most suitable position is converted into using the reference backing surface and the right-angle elbow surface of the telescopic scale of the drilling device to simultaneously press against the edge of the processing board surface and clamp and lock the position dimensions on the processing board surface, and directly inserting the drill bit for drilling into the guiding length cavity of the bushing of the drilling device and then drilling the hole, which is easier to control the drilling processing accuracy and reduce the difficulty. The drilling accuracy is guaranteed by the bushing with a fixed position dimension of the hole template unit, reducing the physical requirements and technical requirements for operation during drilling, and also greatly improving the production efficiency.

[0040] The positioning dimensions of this drilling device can also be used conversely to use the outer contour of the hole template unit as a marking line and marking line point drawing tool for the processing board surface.

[0041] The characteristics of the components on the hole template unit enable the interchangeability of different specifications of hole template units on the drilling device, increasing the diversity of the drilling specifications of the drilling device and expanding the scope of drilling applications.

[0042] For multiple processing plates with the same and consistent drilling position dimensions to be processed, the adjusted and fixed position dimensions of the drilling device can be reused, reducing repetitive labor.

[0043] The drilling device is a pair of axially symmetric drilling devices that can meet the drilling requirements of processing plates with position dimensions in the axially symmetric direction, thereby improving the drilling efficiency.

[0044] Through the above technical solutions and methods, the deficiencies and defects in the background technology are solved, achieving the purpose of eliminating the work of drawing marking line points before drilling, reducing the technical difficulty requirements for operating the drilling, improving the drilling accuracy, increasing the scope of drilling applications, and improving work efficiency.

[0065] The starting point hole template bushing (32) of the hole template unit (3) is vertically and fixedly connected to the rectangular hole template reference surface (31). The axis line of the starting point hole template bushing (32) is also perpendicular to the hole template reference surface (31). The through hole of the starting point hole template bushing (32) penetrates through the hole template reference surface (31) to form a through hole. On one side of the end line of the hole template reference surface (31), a rectangular hole template backrest sliding surface (34) is vertically and fixedly connected upward.

And the axis lines of the multiple coupling bushings (33) are all perpendicular to the hole template reference surface (31). They are respectively associated and corresponding to the position dimension distances from the starting point hole template bushing (32) and the hole template backrest sliding surface (34). The distances of the center points (33-1) of the multiple respective coupling bushings to the center point (32-1) of the starting point hole template bushing are respectively determined values.

[0068] The diameters of the bushing holes between the starting point hole template bushing (32) and the multiple coupling bushings (33) can be the same or different, or they can coincide to form only one starting point hole template bushing (32). The through holes of the center points (33-1) of the multiple respective coupling bushings penetrate through the hole template reference surface (31) to form through holes.

[0069] The center points (33-1) of the other multiple associated bushings are only associated respectively with the center point (32-1) of the starting point hole template bushing and the position dimensions of the hole template backrest sliding surface (34). The center points (33-1) of the multiple associated bushings are composed of different specifications of hole template units (3) determined by the structure method of the center point (32-1) of the starting point hole template bushing and the position dimensions of the hole template backrest sliding surface (34), enabling interchangeability in the use between different specifications of hole template units (3), and increasing the diversity of the hole template units (3) of the drilling device.

[0070] The center point (32-1) of the starting point hole template bushing is on the drilling device, and the corresponding point on the processing board surface is the drilling center point of the processing board surface.

[0071] All the starting point hole template bushings (32) or associated bushings (33) have their respective guiding hole lengths of a certain length. When the guiding hole diameter is less than 10 mm, a guiding hole length more than 3 times the diameter can ensure the vertical accuracy of drilling.

[0072] The hole template backrest sliding surface (34) and the hole template pointer surface (36) are pressed against and move and are fixed along the position dimensions on the hole template connecting backing surface (16) and the longitudinal scale ruler surface (18) to determine the scale value pointed to by the hole template pointer line (37). The quick-release connection combined fastener (51) passes through the through-hole chute (17) and is pressed and fastened on the longitudinal scale ruler surface (18) through the through-hole of the hole template backrest sliding surface (35). The scale value of its position dimension is the longitudinal position dimension on the drilling device, equivalent to the vertical distance dimension from the center point (32-1) of the starting point hole template bushing to the reference backing surface (13). It is equivalent to the vertical longitudinal value from the drilling center point on the processing board surface to the corresponding edge of the processing board surface.

[0073] The bottom surface formed by the connection of the adjusting clamping reference surface (11) and the hole template reference surface (31) is in the same plane position.

[0074] The horizontal value and the vertical value of the drilling center point on the processing board surface and the corresponding edge are respectively adjusted to the horizontal position dimension and the vertical position dimension on the drilling device. The center point (32-1) of the starting point hole template bushing of the drilling device corresponds to the drilling center point on the processing board surface.

[0075] In the first step, use the horizontal scale pointer line (25) to indicate the center point (32-1) of the starting point hole template bushing: While fastening to the limiting backing surface (19), adjust and move the horizontal scale pointer line (25) on the horizontal scale pointer (23) to be parallel and aligned with the horizontal starting point position on the side of the center point (32-1) of the starting point hole template bushing, that is, the vertical position dimension distance from the center point (32-1) of the starting point hole template bushing to the hole template connecting backing surface (16), which is equal to the vertical distance dimension value from the center point (32-1) of the starting point hole template bushing to the hole template back sliding surface (34).

[0076] In the second step, adjust the relative horizontal position dimension of the drilling device: Utilize the starting point position of the horizontally positioned scale pointer line (25), adjust the right-angle elbow surface (21) of the telescopic gauge to the corresponding scale value on the horizontal scale telescopic gauge (20) and fasten it with the telescopic gauge fastener combination (22), which is equivalent to adjusting the horizontal value of the vertical distance dimension from the drilling center point on the processing board surface to the corresponding edge of the processing board surface.

[0077] In the third step, adjust the relative vertical position dimension of the drilling device: That is, adjust the position dimension of the scale value where the hole template pointer line (37) is pressed against the vertical scale gauge surface (18), which is equivalent to adjusting the vertical position dimension perpendicular to the reference backing surface (13) from the center point (32-1) of the starting hole point template bushing, that is, the vertical value, and is equivalent to adjusting the vertical value of the vertical distance dimension from the drilling center point on the processing board surface to the corresponding edge of the processing board surface.

[0078] By operating the above steps on the drilling device, the position dimension to be drilled can be adjusted, thus saving the operation of drawing marking line points on the processing board surface. The position dimension is directly displayed as the scale value on the drilling device on the corresponding scale of the pressure gauge.

[0079] Lock and fasten the relative horizontal and vertical dimensions of the gauge on the drilling device. At the same time, the right-angle elbow surface (21) of the telescopic gauge of the entire drilling device and the reference backing surface (13) are pressed against the corresponding edges of the processing board surface to obtain all the drilling position dimensions. At the same time, use a large clamp (14) to clamp the entire drilling device on the processing board surface and lock it to prevent the sliding and movement of all the drilling position dimensions. Pressing and clamping on the processing board surface reduces the operation difficulty, is convenient for control, and improves the operation speed.

[0080] For the drilling device locked on the processing board surface by the large clamp (14), the center point positions of all bushings are fixed to the position of the processing board surface. After the drill bit of the drill is directly inserted into the guiding length cavity in the bushing, drilling is carried out. Thus, the accuracy of the hole template unit (3) of the drilling device itself is used to improve the drilling accuracy, reducing the technical difficulty requirements for the body operation.

[0081] The entire drilling device can omit the process of marking the point positions, and at the same time has the function of being used as a point position for marking lines on the processing board surface. The marking lines and the point positions of their edges can be drawn with the shape of the hole template unit (3) therein.

[0082] The device is a pair of drilling devices that are axisymmetric, and meets the drilling requirements for the position dimensions of the processing board surface that is axisymmetric.

[0083] For those with the same and consistent requirements for the drilling position dimensions, the repeated drilling operation can be directly carried out using the fixed position dimensions on the drilling device, saving the time of repeated labor.

[0084] The relationship between the position dimensions formed by the hole template back sliding surface (34) of the hole template unit (3), the starting point hole template bushing (32), the center point (32-1) of the starting point hole template bushing, each associated bushing (33), and the center point (33-1) of each associated bushing determines the position dimension of the center point (32-1) of the starting point hole template bushing. At the same time, the position dimensions of each associated bushing (33) are also determined. By determining the position dimension of the overall hole template unit (3), the dimensional tolerance value and precision value between the bushings of the hole template unit (3) are solved.

[0085] There is interchangeability between the hole template units (3), and hole template units (3) with bushings of more different sizes and specifications can be interchanged on the drilling device to increase the applicable range of different drilling requirements.

[0086] The drilling device fixed by the vise (14) has its drilling position dimensions fixed on the processing board surface without moving. At the same time, it also ensures that the drill bit of the drilling directly penetrates into the fixed guiding slide hole and then carries out the drilling operation, simplifies the drilling operation, and improves the drilling accuracy, thereby reducing the physical and operation technical difficulty requirements for the operator and achieving the purpose and effect of inventing this drilling device.

[0087] The preferred embodiments of the present invention disclosed above are only for helping to illustrate the present invention. The preferred embodiments do not describe all details in detail, nor limit the invention to the specific embodiments described.
