AI Technical Summary
[0003]现有的门框加工机床存在着一些不足之处,现逐一介绍:1、现有加工机床一般只具备一个加工工位,故而只能够同时加工一个门框,加工效率相对较低;2、现有加工机床的夹具结构中,一般是将门框放置在支撑台上,然后通过夹具下移而实现对门框的夹持固定,但是同一规格的门框也会存在着尺寸上的误差,因此,通过夹具下移而实现对门框的夹持固定时,不同门框的上表面高度会因为厚度误差而存在差异且差异是不可控的,又由于加工机床的刀具一般是以支撑台作为参照点而按照预设程度对门框进行加工,因此,门框的厚度误差会影响到最终的加工结果的精度
本方案中,夹具同时存在两个加工工位,因此能够同时实现对两个门框的加工,加工效率更高;

Description
Technical Field
[0001] This utility model relates to the field of door frame processing, specifically to a dual-station door frame processing center. Background Technology
[0002] Door frames are a common component of doors in daily life. Their processing involves cutting, drilling, milling, and other steps, requiring specialized machine tools.
[0003] Existing door frame processing machine tools have some shortcomings, which will be introduced one by one: 1. Existing machine tools generally only have one processing station, so they can only process one door frame at a time, resulting in relatively low processing efficiency; 2. In the fixture structure of existing machine tools, the door frame is generally placed on a support platform, and then the door frame is clamped and fixed by moving the fixture downward. However, door frames of the same specification may have dimensional errors. Therefore, when clamping and fixing the door frame by moving the fixture downward, the height of the upper surface of different door frames will vary due to thickness errors, and the differences are uncontrollable. Furthermore, since the cutting tools of the machine tool generally use the support platform as a reference point to process the door frame according to a preset degree, the thickness error of the door frame will affect the accuracy of the final processing result.
[0004] Based on the above problems, this utility model proposes a dual-station door frame machining center. Utility Model Content
[0005] To address the problems mentioned in the background above, this utility model provides a dual-station door frame machining center.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows.
[0007] A dual-station door frame machining center includes a bed; a fixture, the fixture including clamping units, multiple clamping units arranged in an array along the length of the bed, each clamping unit including a slide, the extension direction of the slide being parallel to the width direction of the bed, a vertically arranged central column at the middle position of the slide, the interior of the slide being hollow and a clamping platform slidingly arranged vertically, the extension direction of the clamping platform being parallel to the width direction of the bed, two clamping platforms in the same clamping unit being respectively located on both sides of the central column along the length of the bed, a cylinder for driving the clamping platform to move is provided in the slide, two corresponding cylinders in the same clamping unit, an upper positioning plate is provided at the upper end of the central column, the two ends of the upper positioning plate being respectively located on both sides of the central column along the length of the bed, the end of the clamping platform near the central column being located directly below the upper positioning plate, four clamping platforms located on the same side of the central column forming a machining station, two machining stations being formed; and a tool system, the tool system having two tools that respectively machine the door frames at the two machining stations.
[0008] Furthermore, the carriage is slidably connected to the linear rails mounted on the bed frame, with the guide direction of the linear rails parallel to the length direction of the bed frame.
[0009] Furthermore, there are four clamping units and eight corresponding cylinders.
[0010] Furthermore, a side positioning plate is provided on the middle column of the clamping unit located on one side of the array direction, and the side positioning plate can move in the vertical direction.
[0011] Furthermore, the tool system includes a cross support and a transverse linear module that drives the cross support to move along the length of the bed. The cross support is provided with a longitudinal support whose extension direction is parallel to the width direction of the bed. The longitudinal support is provided with a movable support 1, a linear module 1 for driving the movable support 1 to move along the width direction of the bed, a movable support 2, and a linear module 2 for driving the movable support 2 to move along the width direction of the bed. Multiple tool units are mounted on the movable support. A rotating bracket is rotatably mounted on the movable bracket 2, and the rotating shaft formed at the rotatable mounting point is connected to a motor mounted on the movable bracket 2. Multiple tool units 2 are mounted on the rotating bracket.
[0012] Furthermore, each clamping unit has a side clamping assembly on one side of its carriage. The side clamping assembly is used to press the end of the door frame on the processing station. There are two side clamping assemblies on the same carriage.
[0013] Furthermore, a side seat is provided on the side of the carriage, and the side clamping assembly includes a slide rail provided on the side of the carriage and a slide column that is slidably connected to the slide rail. The guiding direction of the slide rail is parallel to the width direction of the bed, and a driving component for driving the slide column to move is provided on the side seat. An L-rod is slidably installed inside the sliding column along the vertical direction. The L-rod is moved by a driving component installed inside the sliding column. The L-bar includes a vertical bar installed inside the sliding column and a horizontal bar installed at the top of the vertical bar on the side of the vertical bar facing the central column.
[0014] Compared with the prior art, the advantages of this utility model are as follows: In this solution, the fixture has two processing stations at the same time, so it can process two door frames at the same time, resulting in higher processing efficiency; Furthermore, the setup of tool unit one and tool unit two not only enables milling, drilling, and cutting of the door frame, but also enables inclined drilling and inclined cutting, achieving diversified processing. Furthermore, in this solution, the door frame is pushed from bottom to top during clamping, so that the upper surface of the door frame is in contact with the lower surface of the upper positioning plate.

Furthermore, the side clamping components, together with the positioning plate and clamping platform, enable effective clamping of the door frame, resulting in more stable clamping.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0018] Example 1 Reference Figures 1-6 A dual-station door frame machining center includes a bed 1 and a tool system 2 and a fixture 3 mounted on the bed 1, wherein: The fixture 3 includes clamping units, and multiple clamping units are arranged in an array along the length of the bed 1. Four are shown in the attached drawings of this solution.
[0019] The clamping unit includes a slide 302, the extension direction of which is parallel to the width direction of the bed 1. The slide 302 is slidably connected to the linear rail 4 set on the bed 1. The guiding direction of the linear rail 4 is parallel to the length direction of the bed 1. The operator can adjust the position of the slide 302, and thus adjust the position of the clamping unit to accommodate door frames of different sizes and specifications. After the position is adjusted, the slide 302 is fixed and locked by a cylinder. The cylinder can be set on the slide 302 and the slide 302 is fixed to the bed 1 by pressing the linear rail 4. This implementation method is existing technology and will not be described in detail here.
[0020] A vertically arranged central column 303 is provided at the middle position of the slide 302. The slide 302 is hollow inside and a clamping platform 305 is slidably mounted in the vertical direction. The extension direction of the clamping platform 305 is parallel to the width direction of the bed 1. There are two clamping platforms 305 in the same clamping unit, located on both sides of the central column 303 along the length direction of the bed 1. Furthermore, a cylinder (not shown in the figure) is provided inside the slide 302 to drive the clamping platform 305 to move. The cylinder can be set inside the slide 302 and drive the clamping platform 305 to move vertically to achieve lifting. The stroke of the cylinder is set slightly longer than the stroke of the clamping platform 305 to ensure that the workpiece can be clamped. Alternatively, a sensor or limit switch can be used to realize the clamping sensing of the workpiece. This implementation method is the prior art and will not be described in detail here. There are two corresponding cylinders in the same clamping unit. The attached figure of this solution shows four clamping units. Therefore, there are eight corresponding cylinders.
[0021] An upper positioning plate 304 is provided at the upper end of the middle column 303. The two ends of the upper positioning plate 304 are located on both sides of the middle column 303 along the length of the bed 1. The end of the clamping platform 305 near the middle column 303 is located directly below the upper positioning plate 304.
[0022] A side positioning plate 301 is provided on the middle column 303 of the clamping unit located on one side of the array direction, and the side positioning plate 301 can move in the vertical direction. The side positioning plate 301 can be moved by existing electric telescopic rod or hydraulic telescopic rod technology, which will not be described in detail.
[0023] Therefore, the four clamping platforms 305 located on the same side of the central column 303 form a processing station. There are two processing stations, and two sets of tool systems 2 are set up to process the door frame on the two processing stations respectively.
[0024] Furthermore, the tool system 2 includes a cross support 201 and a horizontal linear module that drives the cross support 201 to move along the length direction of the bed 1. The cross support 201 is provided with a longitudinal support 202 whose extension direction is parallel to the width direction of the bed 1.
[0025] The longitudinal support 202 is provided with a movable support 1, a linear module 1 for driving the movable support 1 to move along the width direction of the bed 1, a movable support 2, and a linear module 2 for driving the movable support 2 to move along the width direction of the bed 1.
[0026] The movable support is equipped with multiple tool units 203. Each tool unit 203 includes a tool holder and a linear module 3 for driving the tool holder to move vertically. The tool holder is equipped with a tool shaft and a tool located at the bottom of the tool shaft. The tool includes, but is not limited to, drill bits, milling cutters, and tool wheels. The tool unit 203 can be used to perform vertical drilling, vertical cutting, and milling on the door frame.
[0027] A rotating bracket is rotatably mounted on the movable bracket 2, and the rotating shaft formed at the rotatable mounting point is connected to a motor mounted on the movable bracket 2. Multiple tool units 204 are provided on the rotating bracket. Tool unit 204 includes tool holder 2 and linear module 4 for driving tool holder 2 to move closer to or away from fixture 3. Tool holder 2 is also provided with a tool shaft and a tool located at the bottom of the tool shaft. The tool is a drill bit or a tool wheel, etc. The rotating bracket is driven by the motor to rotate, so that tool holder 2 is arranged at an angle, thereby realizing the oblique hole or oblique cutting of the door frame.
[0028] It should be noted that the linear module mentioned in this article can use existing lead screw linear motion technology, which is common in existing 3D printers and other fields. It is a technology that can be implemented with existing technology and will not be elaborated on.
[0029] The working process of Example 1: The worker places the door frame on the clamping platform 305, with one side of the door frame along the width direction contacting the side positioning plate 301 and one side along the length direction contacting the central column 303. Then, the clamping platform 305 is moved upward by the cylinder, so that the upper surface of the door frame abuts against the upper positioning plate 304 and the door frame is clamped. At this time, regardless of whether there is an error in the thickness of the door frame, after clamping, the upper surface of the door frame is flush with the lower surface of the upper positioning plate 304. Since the height of the lower surface of the upper positioning plate 304 is fixed, the problem that the clamping method from top to bottom may affect the accuracy of the processing result of the door frame surface can be solved. Then, the door frame is processed by the tool system 2, including but not limited to drilling, milling and cutting, oblique holes and oblique cuts.
[0030] Example 2 In Embodiment 1, although the problem that the top-down clamping method can easily affect the accuracy of the door frame surface processing results is solved, only one side of the door frame is clamped, which is not conducive to subsequent machine tool processing operations. Therefore, Embodiment 2 is proposed.
[0031] Reference Figure 7 and Figure 8 Each clamping unit has a side clamping component on one side of its carriage 302. The side clamping component is used to press the end of the door frame on the processing station to improve the stability of the clamping. It should be noted that since there are two processing stations, there are two side clamping components on the same carriage 302.
[0032] Specifically, a side seat 306 is provided on the side of the slide 302. The side clamping assembly includes a slide rail 307 provided on the side of the slide 302 and a slide column 308 that is slidably connected to the slide rail 307. The guiding direction of the slide rail 307 is parallel to the width direction of the bed 1. A drive component 309 is provided on the side seat 306 for driving the slide column 308 to move. The drive component 309 can adopt existing electric telescopic rod technology, etc., which will not be described in detail.
[0033] An L-rod 310 is slidably installed in the sliding column 308 along the vertical direction. The L-rod 310 is driven to move by a second driving component installed in the sliding column 308. Similarly, the second driving component can adopt existing electric telescopic rod technology, etc., which will not be elaborated further.
[0034] Furthermore, the L-bar 310 includes a vertical bar that is vertically disposed within the sliding column 308 and a horizontal bar disposed at the upper end of the vertical bar and located on the side of the vertical bar facing the central column 303.
[0035] The working process of Example 2 is as follows: After clamping the door frame in Embodiment 1, the L-bar 310 can be driven to move in the planar coordinate system through the cooperation of the first driving component 309 and the second driving component, so that the crossbar presses the door frame from above. In this way, combined with the clamping method of Embodiment 1, the final clamping of the door frame can be achieved and the clamping is more stable.
[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
