Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a multi-functional positioning fixture for drilling holes in insulating glass. Background Technology

[0002] Insulating glass, as a building material with excellent heat and sound insulation properties, is widely used in modern buildings. During the further processing of insulating glass, it is often necessary to drill holes in its surface according to design requirements to achieve the purpose of installing, fixing, or setting special functional components. Drilling is a high-precision process, and its processing quality directly depends on whether the workpiece is accurately and stably positioned and clamped before drilling.

[0003] In current production practices, various types of clamps are typically used to position and fix insulated glass units. However, the physical properties of insulated glass present inherent challenges to clamping. Its surface is made of glass, which is hard but has poor toughness, especially in the edge areas, where it is highly susceptible to micro-cracks or even breakage under localized stress. Traditional clamps often use rigid jaws, requiring sufficiently large clamping forces to ensure the workpiece does not shift during drilling.

[0004] When a large clamping force is applied to the limited contact area of ​​the insulated glass unit through rigid jaws, extremely high local pressure is generated. This stress concentration is the main cause of edge breakage, surface indentation, or hidden cracks in the insulated glass unit during clamping, directly affecting product yield and production costs. To avoid damaging the glass, operators often try to reduce the clamping force, but this introduces new problems. Insufficient clamping force cannot provide stable and reliable support for the drilling process. Under the impact load of the high-speed rotating drill bit, the workpiece is prone to slight vibration or displacement, resulting in machining defects such as out-of-tolerance hole position accuracy and non-round hole shape, which also fails to meet high-quality production requirements. It is evident that existing technologies present an irreconcilable contradiction between clamping stability and workpiece safety, lacking an effective structure that can provide sufficient support to ensure positioning accuracy while avoiding stress concentration damage to the workpiece.

[0005] Therefore, this utility model proposes a multi-functional positioning fixture for drilling holes in insulating glass to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a multi-functional positioning fixture for drilling holes in insulating glass, which aims to improve the problems of existing positioning fixtures for drilling holes in insulating glass being prone to damage to the glass due to stress concentration during the clamping process, and the difficulty in balancing clamping stability and workpiece safety.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional positioning fixture for drilling holes in hollow glass, comprising a support platform, a slide groove and a slide plate, wherein the slide groove is opened above the support platform and the slide plate is slidably connected to the slide groove, and further comprising clamping components, wherein the clamping components are symmetrically arranged and fixedly connected to the slide plate by connecting members; The clamping assembly includes a receiving plate, an electric push rod, a slide rod, a clamping plate, and a protective mechanism. The receiving plate is fixed to the slide plate via the connector. The electric push rod is fixedly connected to the receiving plate. One end of the slide rod is fixedly connected to the receiving plate. The clamping plate is slidably connected to the slide rod. The rear part of the clamping plate is connected to the output end of the electric push rod via a connecting rod. The protective mechanism is fixedly connected to the front end of the clamping plate away from the receiving plate. Preferably, the protective mechanism includes an elastic pad and a buffer layer, the elastic pad being attached to the front end of the clamping plate, and the buffer layer being attached to the side of the elastic pad away from the clamping plate; Preferably, the clamping assembly further includes a limiting plate, which is fixedly connected to the other end of the slide rod away from the receiving plate; Preferably, one end of the connecting rod is rotatably connected to the output end of the electric push rod, and the other end of the connecting rod is rotatably connected to the rear part of the clamping plate; Preferably, the connector is an L-shaped bracket, the vertical part of the connector is fixedly connected to the receiving plate, and the horizontal part of the connector is fixedly connected to the sliding plate; Preferably, it also includes a controller, which is electrically connected to the electric push rod in each of the clamping assemblies; Preferably, the controller is also electrically connected to a power mechanism for driving the slide plate to move along the chute; Preferably, there are two sets of clamping components, and the two sets of clamping components are arranged opposite each other along the length direction of the slide groove.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that when rigid clamps are used to directly clamp insulating glass, the glass edge is easily damaged or indented due to the concentration of contact stress. By setting a protective mechanism consisting of a buffer layer and an elastic pad at the front end of the clamping plate, the present invention achieves the effects of uniformly distributing clamping force, effectively protecting glass workpieces, and improving product yield.

[0009] 2. This utility model solves the problems of low positioning accuracy, poor repeatability, and low production efficiency caused by relying on manual positioning and clamping in the prior art by using a controller to coordinate the control of a precision drive and guide mechanism composed of an electric push rod, connecting rod, clamping plate, and sliding rod. It achieves the technical effect of automated and high-precision repeated positioning of insulating glass, and significantly improves the processing accuracy and overall production efficiency of subsequent drilling processes.

[0010] 3. This utility model solves the problem in the prior art where a single clamping device cannot simultaneously handle the rapid loading and unloading of large workpieces and high-precision positioning, resulting in a cumbersome and inefficient overall operation process. It achieves the technical effect of combining coarse and fine adjustment, and enabling rapid loading and unloading and precise clamping in parallel, thereby enhancing the adaptability of the equipment to workpieces of different sizes and the ease of operation.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-5 One embodiment of this utility model is a multi-functional positioning fixture for drilling holes in hollow glass, which includes a support platform 1 as the mounting base of the entire device. A slide groove 5 is provided on the top of the support platform 1, and a slide plate 6 is slidably connected inside the slide groove 5. By sliding the slide plate 6 on the slide groove 5, the overall rough positioning of the fixture can be achieved. A clamping assembly 3 is fixedly connected to the slide plate 6 via a connector 2. Preferably, there are two sets of clamping assemblies 3, which are arranged opposite each other along the length of the slide groove 5 to symmetrically clamp the insulating glass. The core structure of each clamping assembly 3 includes a receiving plate 303, an electric push rod 302 fixedly connected to the receiving plate 303, and a slide rod 403 also fixedly connected to the receiving plate 303. The receiving plate 303 serves as the mounting base inside the clamping assembly 3, providing a stable and reliable mounting platform for the electric push rod 302 and the slide rod 403, ensuring the stability of the driving force transmission. The connector 2 is preferably an L-shaped bracket. The horizontal part of the connector 2 is fixedly connected to the slide plate 6, and the vertical part of the connector 2 is fixedly connected to the receiving plate 303, thereby firmly installing the entire clamping assembly 3 on the slide plate 6. Inside the clamping assembly 3, a clamping plate 304 is slidably connected to the slide rod 403. The rear part of the clamping plate 304 is connected to the output end of the electric push rod 302 via the connecting rod 305. When the electric push rod 302 is working, the output end of the electric push rod 302 extends and retracts, driving the clamping plate 304 to perform precise reciprocating linear motion along the axis of the slide rod 403 via the connecting rod 305. At the front end of the clamping plate 304 away from the receiving plate 303, a protective mechanism 4 is fixedly connected. The protective mechanism 4 is in direct contact with the insulating glass to be processed and is used to protect the glass surface from damage during the clamping process. The protective mechanism 4 is composed of an elastic pad 402 and a buffer layer 401 stacked together. The elastic pad 402 is directly attached to the front clamping surface of the clamping plate 304, while the buffer layer 401 is attached to the side of the elastic pad 402 away from the clamping plate 304. When clamping the workpiece, the buffer layer 401 and the elastic pad 402 can generate elastic deformation, increasing the contact area with the insulating glass, thereby dispersing the clamping stress and avoiding excessive local pressure that could damage the glass. At the same time, at the other end of the slide rod 403 away from the receiving plate 303, a limiting plate 404 is fixedly connected as a mechanical limiter. The limiting plate 404 can prevent excessive displacement of the clamping plate 304, prevent the protective mechanism 4 from being damaged by excessive compression, and ensure the safety of operation. In terms of drive connection, one end of the connecting rod 305 is rotatably connected to the output end of the electric push rod 302, and the other end of the connecting rod 305 is rotatably connected to the rear of the clamping plate 304. This double rotational connection transmission method smoothly transmits the linear thrust of the electric push rod 302 to the clamping plate 304, ensuring that the movement of the clamping plate 304 under the guidance of the slide rod 403 is smooth and without jamming. The entire clamping action is coordinated and controlled by the controller 301. The controller 301 is electrically connected to the electric push rod 302 in each clamping assembly 3, and can independently or in conjunction with the preset program control the extension and speed of the electric push rods 302 on both sides. To achieve automated control of coarse positioning, the controller 301 is also electrically connected to the power mechanism that drives the slide plate 6 to move along the slide groove 5. This power mechanism can be a combination of a servo motor and a ball screw, or a linear motor. Through the instructions of the controller 301, the position of the slide plate 6 on the slide groove 5 can be precisely controlled, thereby completing the automated coarse positioning of the entire clamping device. In the L-shaped bracket structure of the connector 2, the vertical part of the connector 2 is fixedly connected to the receiving plate 303 by bolts, and the horizontal part of the connector 2 is also fixedly connected to the slide plate 6 by bolts. This connection method is not only firm and reliable, but also facilitates the installation, disassembly and maintenance of the equipment. In order to achieve symmetrical clamping of the insulating glass on both sides, there are two sets of clamping components 3. These two sets of clamping components 3 are arranged opposite to each other along the length of the slide groove 5 and are both installed on the same slide plate 6, or respectively installed on two slide plates 6 that can move independently or in conjunction on the slide groove 5, so as to adapt to the clamping requirements of insulating glass of different sizes.

[0015] Working principle: During operation, the insulating glass to be processed is first placed on the support table 1. The controller 301 drives the power mechanism for driving the slide plate 6 to move along the slide groove 5 according to the input command, so that the slide plate 6 carrying the two sets of clamping components 3 moves quickly along the slide groove 5 to the preset coarse positioning position, completing the rapid loading and preliminary alignment of the workpiece. Subsequently, the precise positioning and clamping stage begins. The controller 301 issues commands to control the electric push rods 302 within the clamping assemblies 3 on both sides. The output ends of the electric push rods 302 extend and push the clamping plate 304 through the connecting rod 305. Guided by the slide rod 403, the clamping plate 304 moves smoothly and linearly towards the edge of the insulating glass. When the protective mechanism 4 at the front end of the clamping plate 304 contacts the insulating glass, the buffer layer 401 and elastic pad 402 on its surface are deformed under pressure, distributing the clamping force evenly on the glass contact surface to achieve flexible clamping. During this process, the controller 301 can achieve differential control of the electric push rods 302 on both sides, thereby fine-tuning the position of the insulating glass until the precise position required for drilling is reached, completing high-precision repeatable positioning. After processing is completed, the controller 301 instructs the electric push rod 302 to move in the opposite direction, and the clamping plate 304 quickly retreats under the pull of the connecting rod 305, disengaging from the insulating glass and completing the release of the clamp. The whole process is highly automated and accurately positioned. Furthermore, the structural design of the protection mechanism 4 effectively avoids damage to fragile workpieces.
