Description

Technical Field

[0001] This utility model relates to the field of marking devices, specifically to a quick marking device for door and window trim. Background Technology

[0002] In the manufacturing process of building doors and windows, the mullion (also known as the center mullion) is an important horizontal component for separating glass or installing hardware, and its processing precision directly affects the airtightness, watertightness, and wind pressure resistance of the entire window. Currently, the industry generally uses the following two marking methods: Manual marking: The operator first uses a measuring tape to measure the positions of the keyhole, drain hole, and corner bracket mounting holes, then marks each point with a scriber or oil-based pen, and finally connects them into a line with a ruler. This method is highly dependent on the operator's skill level, and measurement errors accumulate step by step, often resulting in tilted hole groups or left-right asymmetry. When switching between different length specifications in batches, repeated repositioning is required, and the marking time for a single line is about 40-60 seconds, becoming a bottleneck in the production cycle.

[0003] Template / CNC-assisted scribing: Some large-scale enterprises manufacture a series of fixed templates or use small CNC drilling and milling machines to "scrubbing before machining". Templates have poor adaptability, requiring a set of templates for each length, resulting in high storage and changeover costs; although CNC solutions offer high precision, they involve large equipment investments and cumbersome programming, making them uneconomical for processes that only require scribing and not drilling.

[0004] Therefore, it is necessary to invent a quick marking device for door and window support materials. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick marking device for door and window trim, comprising a workbench, a V-shaped groove on the surface of the workbench, a side plate fixedly connected to one side of the workbench, a driving component on the side of the side plate away from the workbench, a clamping arm above the driving component and the workbench, an opposing component above the clamping arm, an adjusting component installed at the upper end of the opposing component, and a marking component installed at the lower end of the side of the adjusting component away from the opposing component.

[0007] Based on the above features: V-groove + positive and negative screw clamping arms + gear tooth plate synchronous centering + lifting scribing assembly, double-sided symmetrical scribing is completed in one clamping.

[0008] Preferably, a positioning groove is provided in the middle of the side plate, a sliding groove is provided on the lower inner wall of the positioning groove, a measuring ruler is symmetrically installed on the upper end of the side plate near the worktable, a base is fixedly connected to the middle of the side plate away from the measuring ruler, and an upper sliding groove is provided on the upper end of the side plate.

[0009] Based on the above features, the clamping arm and scribing assembly are guaranteed to have accurate three-way guidance and reading.

[0010] Preferably, the drive assembly includes a positive and negative screw and a movable nut symmetrically connected to the outside of the positive and negative screw, and a connecting seat is fixedly installed on the upper end of the movable nut.

[0011] Based on the above characteristics, the forward and reverse rotation adjustment of the screws can realize the synchronous clamping or loosening of the two clamping arms.

[0012] Preferably, the opposing assembly includes a gear and toothed plates A and B symmetrically connected on both sides of the gear, toothed plates A and B are arranged opposite to each other, and a limit plate is fixedly installed at the lower end of toothed plates A and B.

[0013] Based on the above features: a single pull, either manually or automatically, can achieve equal and opposite movements of the two marking components.

[0014] Preferably, the adjustment assembly includes an L-shaped plate and a slider connected to the lower end of the L-shaped plate, and a lifting cylinder is installed on the upper end of one side of the L-shaped plate.

[0015] Based on the above features: the marking assembly can be moved horizontally as a whole and quickly raised and lowered to adapt to profiles of different heights.

[0016] Preferably, the marking assembly includes a protective housing and a straight groove at the lower end of the protective housing. An adjusting screw is installed in the middle of the inner cavity of the protective housing, and a handle is installed on one side of the outer end of the protective housing. An adjusting nut is threaded onto the external side of the adjusting screw.

[0017] Based on the above features, the position of the scribing knife can be adjusted slightly laterally by rotating the handle.

[0018] Preferably, a spring collet is fixedly connected to the lower end of the adjusting nut, and a scribing knife is inserted into the lower end of the spring collet.

[0019] Based on the above features: the cutter head has constant elastic pressure, can be quickly replaced after wear, and requires no tools.

[0020] The beneficial effects of this utility model are: It can achieve automatic centering and positioning of profiles. The 90° V-groove of the worktable can complete the radial self-centering of the profiles. When the drive screws are adjusted in both directions, the two sets of clamping arms can be aligned synchronously and the two ends of the centering clip can be clamped quickly, eliminating the need to repeatedly measure the edge reference and improving clamping efficiency. It can zero out at once and scribing lines on both sides simultaneously. After the "zero position" reference is determined, pull one side tooth plate A, and the gear will drive tooth plate B to move in the opposite direction at equal distances, ensuring that the left and right scribing blades are always symmetrical about the center. With the help of a two-way measuring ruler, it can quickly complete the scribing of paired hole positions, solving the cumulative error caused by the secondary alignment of traditional flip profiles.

[0021] The scribing knife can be adjusted horizontally at the micrometer level. With each turn of the handle, the adjusting nut can move the spring collet and scribing knife by 1mm, which can quickly complete the fine adjustment of the lock hole and hinge hole by ±0.1mm horizontally.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] See attached document Figure 1-4This utility model provides a quick marking device for door and window profiles, including a workbench 1. A V-groove 2 is formed on the surface of the workbench 1, with an included angle of 90°. The bottom of the groove is 8mm from the upper surface of the workbench 1, accommodating profiles with widths of 35-90mm. The worker simply places the profile into the V-groove 2 to center it on the workbench 1. A side plate 3 is fixedly connected to one side of the workbench 1. A drive assembly 4 is located on the side of the side plate 3 away from the workbench 1. A clamping arm 5 is located above the drive assembly 4 and the workbench 1. The drive assembly 4 includes positive and negative screws 41 and movable nuts 42 symmetrically connected to the outside of the positive and negative screws 41. Supports and bearings are provided at both ends of the positive and negative screws 41, and the device is driven by a motor (a 57 stepper motor, with the pulse count set by a PLC). The 50pulse clamping arm 5 has a stroke of 30mm, ensuring that clamping of different lengths of ejector can be completed within 5 seconds. This allows the positive and negative screws 41 to be adjusted in both directions. At this time, the two movable nuts 42 can move in opposite directions on the outer walls of the positive and negative screws. A connecting seat 43 is fixedly installed on the upper end of the movable nuts 42. When the movable nuts 42 move in opposite directions, the clamping arm 5 can be moved synchronously through the connecting seat 43, which is convenient for clamping and fixing the ejector on both sides according to its length. An opposing component 6 is set above the clamping arm 5. An adjusting component 7 is installed on the upper end of the opposing component 6. A scribing component 8 is installed on the lower end of the side of the adjusting component 7 away from the opposing component 6. After the ejector is positioned and clamped, the adjusting component 7 and the scribing component 8 can be moved in opposite directions through the opposing component 6, which is convenient for scribing symmetrical installation lines on both sides at once.

[0026] A positioning groove 31 is provided in the middle of the side plate 3. The positioning groove 31 is a long rectangular structure. The clamping arm 5 can pass through the positioning groove 31 and be positioned above the worktable 1. A sliding groove 32 is provided on the lower inner wall of the positioning groove 31 to facilitate the guide and translation of the clamping arm 5. A measuring ruler 33 is symmetrically installed on the upper end of the side plate 3 near the worktable 1. The measuring ruler 33 is a bidirectional ruler. The zero position coincides with the center of the worktable 1. The surface is marked with scales, which can directly read the symmetrical hole positions. When the opposing component 6 drives the adjusting component 7 and the scribing component 8 to move from the center zero position to one side, the other side simultaneously obtains symmetrical scales at equal distances, which can scribing the left and right symmetrical installation lines at one time. A base 34 is fixedly connected in the middle of the side plate 3 away from the measuring ruler 33. A bearing seat is provided in the middle of the base 34. An upper sliding groove 35 is provided on the upper end of the side plate 3 to guide the adjusting component 7 and the scribing component 8, so that the two keep moving in parallel.

[0027] The opposing component 6 includes a gear 61 (with a rotating shaft installed in the middle of the gear 61, the bottom of the rotating shaft being rotatably connected to the upper end of the bearing seat in the middle of the base 34, and the base 43 being able to support the gear 61 from below) and toothed plates A62 and B63 symmetrically connected on both sides of the gear 61. The toothed plates A62 and B63 are arranged opposite to each other. The ends of the toothed plates A62 and B63 closest to the gear 61 are connected and fixed to the lower end of the adjusting component 7. When the toothed plate A62 is pulled to move, the toothed plate B63 will move synchronously in the opposite direction. The lower ends of the toothed plates A62 and B63 are fixedly installed with limit plates 64. The limit plates 64 at the lower ends of the toothed plates A62 and B63 are slidably connected above the connecting seat 43 (a limit groove is opened above the connecting seat 43) to facilitate the guide translation of the toothed plates A62 and B63.

[0028] The adjusting assembly 7 includes an L-shaped plate 71 and a slider 72 connected to the lower end of the L-shaped plate 71. The L-shaped plate 71 is inverted and is slidably connected to the upper slide groove 35 via the slider, facilitating the guiding and translational movement of the adjusting assembly 7. A hole is provided on the surface of the L-shaped plate 71, and a lifting cylinder 73 is installed on the upper end of one side of the L-shaped plate 71. The piston at the output end of the lifting cylinder 73 can pass through the hole to drive the marking assembly 8 to adjust its height (the upper end of the marking assembly 8 is connected and fixed to the piston; the connection method can be bolt fixing, and the lifting cylinder 73 is fixed to the L-shaped plate 71 by bolts). The marking assembly 8 includes a protective housing 81 and a straight groove 82 formed at the lower end of the protective housing 81. An adjusting screw 83 is installed in the middle of the inner cavity of the protective housing 81. Bearings are symmetrically arranged on the inner walls of both ends of the protective housing 81 to facilitate the connection of the adjusting screw 83. A handle 84 is installed on one side of the outer end of the protective housing 81. The handle 84 is connected to one end of the adjusting screw 83. When the adjusting screw 83 is rotated forward and backward by the handle 84, an adjusting nut 85 is threadedly connected to the external end of the adjusting screw 83. At this time, the adjusting nut 85 can move left and right. The lower end of the adjusting nut 85 is fixedly connected to... A spring collet 851 is attached to the lower end of which a scribing blade 852 is inserted. The spring collet 851 and the scribing blade 852 pass through a straight groove 82. This facilitates the scribing blade 852 to extend downwards out of the protective housing 81 and prevents the adjusting nut 85 from rotating with the adjusting screw 83. When the adjusting nut 85 moves left or right, the spring collet 851 can drive the scribing blade 852 to move, allowing the scribing blade 852 to be adjusted laterally (while the opposing component 6 can drive the scribing blade 852 to be adjusted longitudinally, meeting the scribing requirements at different positions on the surface of the material).

[0029] It should be noted that: the scribing cutter 852 can use a ∅2mm carbide tip with a tip radius R=0.2mm; the lead of the adjusting screw 83 is 1mm; the scribing cutter moves 1mm laterally with each rotation of the handle 84; the lifting cylinder 73 is an SMCCQ2B32-25D with a stroke of 25mm, an air supply of 0.4MPa, and a descent buffer time of 0.3s; the vertical pressure between the scribing cutter 852 and the profile surface is controlled by the compression of the spring collet 851 to be (2±0.2)N. The 852 marking knife can also be replaced with a ∅1mm ball bearing marking pen or an oil-based pen, with the pressure reduced to (0.8±0.1)N to prevent the protective film from being punctured.

[0030] The usage process of this utility model is as follows: Place the middle muzzle into the V-groove 2, start the motor, so that the forward and reverse screws 41 can drive the clamping arms 5 to move in opposite directions to clamp the middle muzzle material. Then pull the toothed plate A62 to make the gear 61 rotate, while the toothed plate B63 moves in the opposite direction at the same time. During this process, observe through the measuring ruler 33. When the lower end of the scribing knife 852 is aligned with the "zero" scale, record that the digital display is at zero. When the toothed plate A62 is moved laterally so that the lower end of the left scribing knife 852 is aligned with the theoretical position of the lock hole 35mm, the right scribing knife 852 will automatically reach -35mm under the action of the gear 61 and the toothed plate B63. At the same time, when the handle 84 is turned, the two scribing knives 852 can be adjusted laterally by ±0.1mm to complete the symmetrical lock hole cross line. Finally, the lifting cylinder 73 is lowered, and the scribing knife 852 can scribble across the surface of the profile to form scribing lines or scratches.

Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
