Abstract
Description
Technical Field
[0001] This utility model relates to the field of devices that can be adsorbed onto smooth surfaces using the principle of vacuum negative pressure, and in particular to a single-head punching and positioning device. Background Technology
[0002] Adsorption devices utilizing the principle of vacuum negative pressure are widely used, such as tool suction cups. Currently, existing technologies employ a vacuum principle, using a suction cup where the tool contacts the wall. By removing the air from the space enclosed by the suction cup and the adsorption surface, the tool is directly adsorbed onto the wall. These tool suction cups require the air between the suction cup and the adsorption surface to be expelled, creating a negative pressure with the outside atmosphere to adhere the suction cup to the surface. It is crucial to maintain a constant vacuum within the suction cup. In applications where a high degree of vacuum is not required, the internal space of the suction cup is typically increased to lower the air pressure within that space, thus creating a negative pressure environment for adsorption. These vacuum suction cups generally incorporate a lever mechanism and a self-locking mechanism.
[0003] Drilling positioning has been widely used in engineering. Chinese patent CN216007858U relates to the field of building construction technology, specifically disclosing a drilling positioning device for building construction. The device includes a movable ring, with telescopic rods fixedly connected to both sides of the movable ring. A connecting block is fixedly connected to the bottom of the telescopic rod on the side furthest from the movable ring. A negative pressure suction cup is movably connected to the bottom of the connecting block. Openings are provided on both the top and bottom sides of the movable ring, and spring hinges are fixedly connected to the inner cavities of these openings. This invention, through the structural design of the threaded column, rotating block, and limiting ring, allows workers to adjust the position of the limiting ring within the inner cavity of the movable ring, preventing deviation during drilling. Furthermore, the longitudinal and transverse positioning plates facilitate positioning of the planned lines on the wall surface. Therefore, this drilling positioning device for building construction achieves the goal of facilitating positioning while preventing deviation during drilling.
[0004] Another type of drilling positioning device, such as a single-head drilling positioning device (that is, positioning only one drill bit), typically uses vacuum adsorption to fix the single-head drilling housing to a smooth surface such as a wall. Then, a sliding plate slides relative to the single-head drilling housing to change the size of the limiting frame, thus positioning the drill bit. In existing single-head drilling positioning devices, both the single-head drilling housing and the sliding plate are flat. When the sliding plate slides to adjust the limiting size, even slight misalignment of the sliding plate can easily cause jamming.
[0005] Therefore, there is an urgent need for a single-head punching positioning device that can effectively avoid the problem of the skateboard getting stuck when it slides.
[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0007] The purpose of this utility model is to provide a single-head punching positioning device. By cooperating with the concave and convex structure on the skateboard through the single-head punching shell, the skateboard can slide more smoothly and avoid the skateboard getting stuck when adjusting the limit size.
[0008] Another objective of this utility model is to provide a single-head drilling positioning device. Through the cooperation between the single-head drilling housing and the limiting frame on the slide plate, as well as the cooperation of multiple movable bearings, the positioning device can be adapted to the positioning of drill bits of different sizes, making it more adaptable.
[0009] To achieve the above objectives, this utility model provides a single-head drilling positioning device, which can be used for drilling positioning of different types of drill bits. It includes at least: a single-head drilling housing, comprising an upper suction cup housing and a lower positioning housing; the suction cup housing is used to accommodate a plate-mounted suction cup unit, which uses the plate-mounted suction cup unit as a lever and, through a lifting action, creates a negative pressure space between the rubber base and the smooth surface, thereby adsorbing the single-head drilling housing onto the smooth surface; the positioning housing has vertically extending ribs on both sides; and a sliding plate with grooves on both sides, the shape and size of which are adapted to the ribs to form a convex-concave fitting slide rail.
[0010] Furthermore, in the above technical solution, when the slide plate slides relative to the single-head perforated housing to the required position, it can be tightened and locked in position by adjusting the slide plate knob.
[0011] Furthermore, in the above technical solution, the middle part of the positioning housing may be provided with a herringbone-shaped first limiting frame, and correspondingly, the middle part of the sliding plate may be provided with an inverted herringbone-shaped second limiting frame; the quadrilateral structure formed by the first limiting frame and the second limiting frame is used to initially limit the drilling bit.
[0012] Furthermore, in the above technical solution, two right-angled slide grooves are symmetrically provided on the positioning housing and the upper part of the first limiting frame. The two right-angled slide grooves are respectively provided with a first bearing and a second bearing, which are used to adjust the position of the first bearing and the second bearing, respectively. Two right-angled slide grooves are symmetrically provided on the slide plate and the lower part of the second limiting frame. The two right-angled slide grooves are respectively provided with a third bearing and a fourth bearing, which are used to adjust the position of the third bearing and the fourth bearing, respectively. The outer edges of the first, second, third and fourth bearings all contact the drilling bit and rotate with the drilling bit, which is used for the precise positioning of the drilling bit.
[0013] Furthermore, in the above technical solution, a fifth bearing can be provided directly below the symmetrical center of the third and fourth bearings on the skateboard, which is used to precisely position the drilling bit together with the first and second bearings when the skateboard is used in reverse.
[0014] Furthermore, in the above technical solution, the plate-mounted suction cup unit may include a rubber base, a square pull rod, and a compression spring. The square pull rod is vertically positioned at the center of the rubber base and fitted with a compression spring. The plate-mounted suction cup drives the square pull rod to move upward, forming the negative pressure space required for vacuum adsorption in this invention.
[0015] Furthermore, in the above technical solution, the suction cup housing and the positioning housing are preferably integrally formed structures.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1) This utility model forms a sliding rail with a concave-convex fit by setting the protruding ribs on both sides of the positioning housing and the corresponding grooves on both sides of the sliding plate. In this way, when the sliding plate is moved to adjust the positioning position of the drill bit, it will not be stuck due to the offset and sliding of the sliding plate, making the drilling positioning adjustment process of the drill bit smoother; the setting of the buckle suction cup unit can use the vacuum adsorption principle to firmly adsorb the single-head drilling housing onto the smooth surface to be drilled, which is very convenient for installation and disassembly.
[0018] 2) This utility model can achieve initial positioning of the drilling bit by means of the cooperation of two limiting frames; when the sliding plate is used in the forward direction, the drilling bit can be precisely positioned at "four points" by means of the cooperation of the first, second, third and fourth bearings; when the sliding plate is used in the reverse direction, the drilling bit can be precisely positioned at "three points" by means of the fifth bearing, the first bearing and the second bearing. "Reverse use" can expand the applicability of the positioning device of this utility model, making it applicable to a wider range of drill bit diameters.

Detailed Implementation
[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.
[0029] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.
[0030] In this document, for ease of description, spatial relative terms such as “below,” “under,” “down,” “above,” “above,” “upper,” etc., are used to describe the relationship of one element or feature to another element or feature in the accompanying drawings. It should be understood that spatial relative terms are intended to encompass different orientations of an object in use or operation, in addition to those depicted in the figures. For example, if an object in the figure is flipped, an element described as “below” or “under” another element or feature would be oriented “above” that element or feature. Thus, the exemplary term “below” can encompass both the downward and upward orientations. An object may also have other orientations (rotated 90 degrees or other orientations), and the spatial relative terms used herein should be interpreted accordingly.
[0031] In this document, the terms "first," "second," etc., are used to distinguish two different elements or parts, and are not used to define specific positions or relative relationships. In other words, in some embodiments, the terms "first," "second," etc., can also be used interchangeably.
[0032] like Figures 1 to 5 As shown, this utility model provides a single-head drilling positioning device for drilling positioning of different types of drill bits (such as the drilling drill bit 1000 in the figure), and includes at least a single-head drilling housing 1 and a sliding plate 2. The single-head drilling housing 1 includes a suction cup housing 11 at the upper part and a positioning housing 12 at the lower part (the suction cup housing 11 and the positioning housing 12 are preferably integrally formed). The suction cup housing 11 is used to accommodate a plate-clamp suction cup unit, which uses the plate-clamp 111 as a lever and a lifting action to create a negative pressure space between the rubber base 116 and a smooth surface (such as a wall, not shown in the figure), thereby adsorbing the single-head drilling housing 1 onto the smooth surface; the positioning housing 12 has vertically extending ribs 121 on both sides. The sliding plate 2 has grooves 21 on both sides, the shape and size of which are adapted to the ribs 121 to form a concave-convex sliding rail.
[0033] This utility model adopts the above-mentioned technical solution. By setting the convex ribs on both sides of the positioning housing and the corresponding grooves on both sides of the sliding plate, a sliding rail with concave and convex fit is formed. In this way, when the sliding plate is moved to adjust the positioning position of the drill bit, it will not be stuck due to the offset and sliding of the sliding plate, making the drilling positioning adjustment process of the drill bit smoother. The setting of the buckle suction cup unit can use the vacuum adsorption principle to firmly adsorb the single-head drilling housing onto the smooth surface to be drilled, making subsequent positioning adjustment more convenient and faster.
[0034] Further as Figures 1 to 5 As shown, when the slide plate 2 slides relative to the single-headed perforated housing 1 to the desired position, it can be tightened and locked in place by the slide plate adjustment knob 23. Specifically, the adjustment knob 23 can be locked by the external hexagonal screw 231 (see reference). Figure 2 ).
[0035] Further as Figures 1 to 5 As shown, the positioning housing 12 has a herringbone-shaped first limiting frame 122 in the middle, and correspondingly, the sliding plate 2 has an inverted herringbone-shaped second limiting frame 22 in the middle; the quadrilateral structure formed by the first limiting frame 122 and the second limiting frame 22 can be used to initially limit the drilling bit 100. Further as... Figures 1 to 5As shown, two right-angled grooves are symmetrically arranged on the upper part of the positioning housing 12 and the upper part of the first limiting frame 122. A first bearing 31 and a second bearing 32 are respectively installed in the two right-angled grooves, which can be used to adjust the positions of the first bearing 31 and the second bearing 32. Two right-angled grooves are symmetrically arranged on the lower part of the sliding plate 2 and the second limiting frame 22. A third bearing 33 and a fourth bearing 34 are respectively installed in the two right-angled grooves, which can be used to adjust the positions of the third bearing 33 and the fourth bearing 34. The outer edges of the first bearing 31, the second bearing 32, the third bearing 33, and the fourth bearing 34 all contact the drilling bit 100 and rotate with the drill bit, for precise positioning of the drilling bit 100. This utility model, through the cooperation of the two limiting frames, can achieve initial positioning of the drilling bit 100, and through the cooperation of the four bearings, can achieve precise "four-point" positioning of the drilling bit 100.
[0036] Further as Figures 2 to 5 As shown, a fifth bearing 35 can be provided on the slide plate 2, directly below the center of symmetry of the third bearing 33 and the fourth bearing 34. This fifth bearing 35 is used to precisely position the drill bit together with the first bearing 31 and the second bearing 32 when the slide plate is used in reverse. "Reverse use" means rotating the slide plate 180 degrees so that it slides into the single-head drilling housing 1. At this time, the fifth bearing 35 can be used in conjunction with the first bearing 31 and the second bearing 32 to achieve "three-point" precise positioning of the drill bit 100. "Reverse use" can expand the applicability of the positioning device of this utility model, making it applicable to a wider range of drill bit diameters.
[0037] Further as Figure 1 , 5 As shown, the plate-mounted suction cup unit of this utility model specifically includes a latch 111, a rubber base 116, a square pull rod 115, and a compression spring 113. The square pull rod 115 is vertically positioned at the center of the rubber base 116 and fitted with the compression spring 113. The top of the square pull rod 115 passes through the suction cup housing 11 and is pinned to the latch 111, i.e., connected by a round-headed pin 112 and an outer retaining spring 114. A circular iron slide 117 is provided at the contact point between the latch 111 and the suction cup housing 11 (i.e., at the lever fulcrum position). Since the housing material of this utility model is ABS (i.e., plastic), frequent friction at this point will affect the service life of the device. Therefore, a circular iron slide is used as a gasket to improve the effect of friction. Through the cooperation of the above structural components of the plate-mounted suction cup unit, the upward movement of the square pull rod 115 driven by the latch 111 can form the negative pressure space for vacuum adsorption of this utility model.
[0038] In use, the single-head drilling positioning device of this utility model is first placed on the smooth surface where drilling is required, and the buckle 111 is pressed to make the entire single-head drilling housing 1 adhere to the smooth surface; then, the slide plate 2 slides relative to the single-head drilling housing 1 through the "concave-convex" sliding rail, so that the drilling bit 100 is initially limited within the quadrilateral limiting frame; further, the drilling bit 100 is precisely positioned by the "four-point positioning" of the first bearing 31, the second bearing 32, the third bearing 33 and the fourth bearing 34, or by the "three-point positioning" of the first bearing 31, the second bearing 32 and the fifth bearing 35; after positioning and drilling, the positioning device of this utility model can be quickly disassembled by releasing the buckle 111.
[0039] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical applications, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. Any simple modifications, equivalent changes, and alterations made to the foregoing exemplary embodiments should fall within the protection scope of the present invention.
