[0033] In the description of the utility model, it should be understood that the terms "first", "second" and the like are used to describe various information in the utility model, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0034] The existing gantry machining equipment is mainly applied to screen fine cutting, high-precision scribing of copper plates in semiconductor manufacturing and various advanced precision manufacturing scenes, and is not biased towards machine tool processing industry, and a circular arc motor is mainly used to realize angle fine adjustment, however, the high manufacturing cost of the circular arc motor increases the overall cost of the equipment, which limits its wide application. Therefore, it is particularly important to develop a mechanism with low cost and effective position adjustment.

[0035] For example, Figures 1 to 6As shown, the utility model embodiment provides a position adjusting mechanism 100 for installing on the base 201 of the gantry machining equipment 200, it includes guide rail module, adjusting module and linear motor 30, guide rail module includes setting up on the linear guide rail 11 of base 201;Adjusting module includes support 21 and swing arm 22, support 21 is located on linear guide rail 11 and is connected with linear guide rail 11 sliding, swing arm 22 is located above support 21, swing arm 22 is used to carry the object to be processed, one end of swing arm 22 is connected with support 21 rotationally, the other end of swing arm 22 is connected with support 21 sliding;Linear motor 30 is used to drive swing arm 22 to swing in the plane direction of support 21 relative to support 21 in the preset radian range, to adjust the position of the object to be processed.

[0036] In the embodiment, linear guide rail 11 is arranged on base 201, which provides a sliding path for the adjusting module, and linear guide rail 11 supports the weight of the entire adjusting module. Support 21 is arranged on linear guide rail 11 and is connected with linear guide rail 11 slidingly. The bottom of support 21 can be provided with a sliding groove and a bearing structure to facilitate sliding cooperation with linear guide rail 11.

[0037] Among them, swing arm 22 is arranged above support 21 to carry the object to be processed. One end of swing arm 22 is connected with support 21 rotationally through a rotating shaft, and the other end is connected with support 21 slidingly, so that swing arm 22 can swing around the rotating shaft within a certain radian range around support 21. In the embodiment, a sliding block can be arranged on swing arm 22, and an arc-shaped guide rail is arranged on support 21. Of course, it can also be arranged in reverse, i.e., an arc-shaped guide rail is arranged on swing arm 22, and a sliding block is arranged on support 21. The sliding block is connected with the arc-shaped guide rail slidingly to make one end of swing arm 22 connected with support 21 slidingly.

[0038] Correspondingly, linear motor 30 can be fixed on support 21 or base 201, generates linear thrust according to the control signal, and drives swing arm 22 to swing within the preset radian range.

[0039] In a specific embodiment, the position adjusting mechanism 100 is installed on the base 201 of the gantry machining equipment 200. Linear guide rail 11 is made of stainless steel material, and support 21 is made of aluminum alloy casting. Linear motor 30 is selected from high-precision and low-noise servo linear motor 30, and is equipped with a precision encoder to realize position feedback. In the machining process, the object to be processed is fixed on swing arm 22. The adjusting module is moved to the target position on linear guide rail 11 to preliminarily process the object to be processed. When it is necessary to further adjust the position of the object to be processed, the control system sends instructions to linear motor 30, and linear motor 30 generates thrust to drive swing arm 22 to swing around the rotating shaft of support 21, thereby realizing the adjustment of the angular position of the object to be processed.

[0040] The position adjusting mechanism 100 adopted in the embodiment is designed by optimizing the structure, adopts the combination of the linear motor 30 and the adjusting module, and replaces the arc motor in the traditional technology, so that the accurate swing adjustment of the workpiece can be realized, and the cost of the linear motor 30 is lower than that of the arc motor, and therefore the manufacturing cost of the gantry machining equipment is reduced.

[0041] As an implementation form, as shown in Figures 4 to 6 The adjusting module 20 includes the first sliding member 23 and the first arc-shaped guide rail 24, the linear motor 30 and the first arc-shaped guide rail 24 are arranged on the upper surface of the support 21, and the swing arm 22 is slidably connected with the first arc-shaped guide rail 24 through the first sliding member 23.

[0042] Specifically, the first sliding member 23 can be a sliding block or a roller, has the characteristics of low friction and high wear resistance, so as to ensure that the resistance is reduced and the movement is stable during sliding. The first sliding member 23 can be fixed at the lower position of the swing arm 22 by bolts, pins or other fastening devices, and the movement of the swing arm 22 is limited on the track of the first arc-shaped guide rail 24.

[0043] The first arc-shaped guide rail 24 and the linear motor 30 are both fixed on the upper surface of the support 21 and located on one side of the first arc-shaped guide rail 24 or adjacent to the first arc-shaped guide rail 24. The linear motor 30 is connected with the swing arm 22 or the first sliding member 23, so as to convert the linear movement of the linear motor 30 into the arc swing of the swing arm 22. In some embodiments, the linear motor 30 can be directly connected and fixed with the swing arm 22, and the swing arm 22 is directly driven to move by the linear motor 30, so that the swing arm 22 moves along the first arc-shaped guide rail 24 with the first sliding member 23.

[0044] In other embodiments, the linear motor 30 is connected and fixed with the first sliding member 23, and the first sliding member 23 is connected and fixed with the swing arm 22, and the first sliding member 23 is driven to move along the first arc-shaped guide rail 24 by the linear motor 30, so that the first sliding member 23 swings with the swing arm 22.

[0045] When the linear motor 30 receives the control signal and generates the linear thrust, the thrust is converted into the arc swing movement of the swing arm 22 around the rotation shaft of the swing arm 22. In this way, the accurate adjustment of the position of the workpiece can be realized without using the arc motor with high cost.

[0046] As an implementation form, as shown in Figures 4 to 6 The adjusting module 20 further includes the second sliding member 25 and the second arc-shaped guide rail 26, the second arc-shaped guide rail 26 is arranged on the upper surface of the support 21, the second arc-shaped guide rail 26 is arranged on the two sides of the linear motor 30 along the length direction of the support 21, and the swing arm 22 is slidably connected with the second arc-shaped guide rail 26 through the second sliding member 25.

[0047] Specifically, in order to further enhance the stability and carrying capacity of the adjustment module 20, while improving the accuracy and balance of the adjustment, the second sliding member 25 and the second arc-shaped guide rail 26 are further added in this embodiment. The second sliding member 25 is similar in function and structure to the first sliding member 23, and slides on the corresponding second arc-shaped guide rail 26. The second arc-shaped guide rail 26 is parallel to the first arc-shaped guide rail 24 and is arranged on both sides of the linear motor 30, so that the swing arm 22 can be evenly supported from two positions during the swing process, thereby improving the stability and accuracy of the adjustment. This double sliding connection mode greatly enhances the stability and carrying capacity of the swing arm 22 during the swing process.

[0048] As an implementation mode, as shown in Figure 4 or Figure 6 , the position adjustment mechanism 100 further comprises a first anti-collision member 40 and a second anti-collision member 50, and the first anti-collision member 40 and the second anti-collision member 50 are used to limit the swing range of the swing arm 22.

[0049] Specifically, as shown in Figure 2 , the swing arm 22 has a length direction L and a width direction W. In order to ensure that the swing arm 22 does not exceed the predetermined safe range during the swing process, thereby avoiding collision or damage with other parts of the equipment, the first anti-collision member 40 and the second anti-collision member 50 are provided in this embodiment to limit the swing range of the swing arm 22, and can also absorb the impact energy of the swing arm 22 to a certain extent, protecting the swing arm 22 and other components from damage. In actual application, the first anti-collision member 40 and the second anti-collision member 50 are installed on the base 201 and located on the left and right sides in the length direction L of the swing arm 22, or can be installed on the support 21. The first anti-collision member 40 and the second anti-collision member 50 can be a telescopic elastic structure, such as a rubber pad, a spring buffer, etc., so as to provide a buffering effect when the swing arm 22 approaches its swing limit, preventing hard collision.

[0050] In actual application, the specific position and shape of the first anti-collision member 40 and the second anti-collision member 50 can be adjusted and optimized according to the specific layout of the gantry machining equipment 200 and the swing requirements of the swing arm 22. For example, they can be designed as adjustable position fixed structures to be adjusted as needed during equipment debugging or maintenance.

[0051] In some embodiments, in order to further improve safety, the position adjustment mechanism 100 can also be equipped with sensors and a control system for real-time monitoring of the position and speed of the swing arm 22, and automatically slowing down or stopping the swing when the swing arm 22 approaches the anti-collision member, thereby avoiding collision.

[0052] As an implementation mode, as shown in Figure 4 or Figure 6As shown, the first anti-collision member 40 and the second anti-collision member 50 are symmetrically arranged on the support 21 along the length direction of the support 21; the adjustment module 20 further comprises an anti-collision block 27, which is fixed on the lower surface of the swing arm 22 and is arranged between the first anti-collision member 40 and the second anti-collision member 50.

[0053] Specifically, in the design of the position adjustment mechanism 100, the first anti-collision member 40 and the second anti-collision member 50 are symmetrically arranged along the length direction of the support 21. In order to further improve the anti-collision effect, the adjustment module 20 further comprises the anti-collision block 27, which is fixed on the lower surface of the swing arm 22 and is arranged between the first anti-collision member 40 and the second anti-collision member 50. When the swing arm 22 approaches its swing limit, the anti-collision block 27 will contact the two anti-collision members. Through the buffering effect of the material (such as rubber, elastic plastic, etc.) of the anti-collision block 27, the impact energy can be effectively absorbed, and the damage caused by hard collision to the swing arm 22 and the workpiece to be processed can be prevented.

[0054] As an embodiment, the preset arc range is between -5 degrees and 5 degrees.

[0055] Specifically, the swing arc range of the swing arm 22 is accurately set to be between -5 degrees and 5 degrees. This range is determined by the arrangement position of the first anti-collision member 40 and the second anti-collision member 50 and the mechanical limiting structure of the swing arm 22. Specifically, the first anti-collision member 40 and the second anti-collision member 50 are respectively located on both sides of the swing path of the swing arm 22, and their relative positions are accurately adjusted according to the preset arc values of -5 degrees and 5 degrees.

[0056] In some embodiments, in order to ensure that the swing arm 22 can accurately and stably stay within the preset arc range during swing, other auxiliary measures such as mechanical limiting pins, electronic limiting switches, etc. can also be used.

[0057] In some embodiments, the swing arc range of the swing arm 22 is accurately set to be between -1 degree and 1 degree. The control system accurately controls the swing of the swing arm 22 according to the preset arc range, ensures that the swing arm 22 swings within -1 degree to 1 degree, and thus improves the processing precision of the equipment.

[0058] As an embodiment, as shown in Figure 3 or Figure 5 As shown, the guide rail module 10 comprises an organ cover 12, which is arranged on the linear guide rail 11 and can be telescoped with the swing of the swing arm 22.

[0059] Specifically, the organ cover 12 is used as a protective cover to cover the linear guide rail 11, so as to prevent external pollutants such as dust and debris from entering the linear guide rail 11, thereby maintaining the cleanliness of the linear guide rail 11 and prolonging the service life.

[0060] In practical applications, the hood 12 adopts a multi-section folding structure, each section is connected through a high-strength elastic connecting piece to form an extensible channel. During installation, the hood 12 is arranged outside the linear guide rail 11, and is connected with the base 201 and the fixed part of the moving swing arm 22 at both ends, so that it can freely extend and retract with the swing of the swing arm 22, and will not hinder the movement trajectory of the swing arm 22.

[0061] In a second aspect, as shown in the drawings, the utility model embodiment provides a gantry machining equipment 200, it includes drive mechanism, machining mechanism 202, base 201 and position adjusting mechanism 100, position adjusting mechanism 100 is installed on base 201, drive mechanism is used to adjust the position of machining mechanism 202, to make machining mechanism 202 carry out processing to the machining object. Figure 1

[0062] Specifically, as described previously, the position adjusting mechanism 100 is installed on the base 201. The drive mechanism includes a plurality of servo motors, a controller, and a transmission device (not shown in the drawings). Among them, the servo motor is connected with the machining mechanism 202 through the transmission device, and drives the machining mechanism 202 to rotate, tool feeding and other actions according to the instruction of the controller. The controller adopts an advanced numerical control system (or encoder), has powerful programming ability and processing capacity, and can accurately control the movement trajectory and speed of the machining mechanism 202 according to the preset machining path and parameters. In the machining mechanism 202, according to the machining requirement, select the appropriate machining tool, such as milling cutter, drill or laser cutting head and so on.

[0063] In the working process, the control system accurately controls the movement trajectory and speed of the machining mechanism 202 through the drive mechanism and the position adjusting mechanism 100 according to the preset machining program and parameters, to realize the accurate machining of the machining object. The gantry machining equipment 200 in the embodiment realizes the precision machining of the complex workpiece by adopting the high-precision, high-stability mechanical structure and the advanced control system, improves the machining efficiency and quality. At the same time, the equipment also has the advantages of easy maintenance and simple operation, and is suitable for various machining occasions.

[0064] As an embodiment, the gantry machining equipment 200 includes a top beam 203 and two support columns 204, the two support columns 204 are installed on the base 201 with a spacing, the top beam 203 is fixedly connected between the two support columns 204, and the machining mechanism 202 is installed on the top beam 203.

[0065] ​Specifically, the base 201 serves as the supporting foundation of the entire device and can be made of high-strength and high-stability materials such as cast iron or welded steel structure to ensure that the device remains stable during processing. The two support columns 204 are spaced apart and mounted on the base 201 and can be made of steel or alloy materials with sufficient load-bearing capacity and bending stiffness. The support columns 204 are fixed to the base 201 by bolting or welding.

The top beam 203 is provided with a sliding rail to facilitate adjustment of the position of the processing mechanism 202 in the horizontal direction.

[0066] In use, the processing mechanism 202 is driven by the driving mechanism to move in the horizontal direction along the top beam 203, and then the processing mechanism 202 is driven to move in a direction perpendicular to the top beam 203 in the horizontal plane, thereby adjusting the position of the processing mechanism 202 and processing the workpiece. When the workpiece is processed to a certain extent and needs to be adjusted in angle position for further processing, the linear motor 30 in the position adjusting mechanism 100 is slidably connected with the arc-shaped guide rail, and the left and right swinging of the swing arm 22 is used to finely adjust the angle position of the workpiece, thereby achieving accurate processing of the workpiece.

[0067] As an embodiment, the base 201 is made of marble.

[0068] Specifically, in the design of the gantry machining device 200, the base 201 serves as the supporting foundation of the entire device, and the selection of its material is crucial. Since the base 201 is provided with a plurality of linear guide rails 11 to improve the load-bearing capacity, marble can provide a stable supporting platform under the requirement of ensuring the accuracy of the guide rail mounting surface, reducing the displacement or deformation of the device during processing due to vibration, thereby improving the load-bearing capacity.
