Description

Technical Field

[0001] The utility model relates to the technical field of thin-walled workpiece processing, and particularly relates to a fixing tool for rapid positioning of workpieces. Background Art

[0002] Due to the need for lightweight design, various thin-walled structural parts are widely used in high-precision demand industries, such as the aerospace manufacturing industry, to reduce weight, lower fuel consumption, and at the same time improve the structural strength and applicable performance of spacecraft or aircraft; therefore, higher precision needs to be ensured during the production and processing of thin-walled workpieces.

[0003] However, since the thickness of thin-walled workpieces usually does not exceed 3 mm, the overall rigidity is poor, the strength is weak, and the structure is complex. The clamping methods for thin-walled workpieces in the prior art are usually as follows: mechanical vise clamping, hydraulic vise clamping, and pressing plate clamping; for rectangular thin-walled workpieces, vise clamping is likely to cause workpiece deformation and only one workpiece can be clamped at a time, resulting in low production efficiency. Although pressing plate clamping can effectively reduce workpiece deformation, during the pressing plate clamping process, manual position adjustment of the workpiece is required. During large-batch production and processing, the manual clamping adjustment speed is slow, the efficiency is low, and at the same time, the labor intensity is too high, causing workers to be tired, making it difficult to ensure the accurate position accuracy of the workpiece, affecting the processing accuracy of the product, resulting in too high a rejection rate, and increasing production costs; secondly, to improve the single-processing efficiency, usually multiple rectangular workpieces are stacked together and fixed, but in this way, the workpieces in the middle part are prone to misalignment and deviation during processing, resulting in processing errors, causing workpiece scrapping, and increasing cost losses. Summary of the Utility Model

[0004] The utility model aims to provide a fixing tool for rapid positioning of workpieces to achieve rapid clamping and fixing of thin-walled rectangular workpieces and improve production efficiency and quality.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A fixing tool for rapid positioning of workpieces, including a fixing table, on which a plurality of rectangular grooves for accommodating workpieces are evenly opened. The size of the rectangular grooves is larger than the size of the workpieces. One vertex angle at the same position of each rectangular groove is used as a reference angle, and the two side surfaces connected by the reference angle are positioning surfaces. Magnet installation grooves are opened on both sides of each reference angle of the fixing table, and magnets are installed in the magnet installation grooves. The magnets adsorb the workpieces to the positioning surfaces; a chip removal groove is opened on the fixing table, and the chip removal groove is located directly below the machining position of the workpiece.

[0006] The principle and advantages of this solution are:

[0007] 1. In actual application, workers only need to place the thin-walled rectangular workpiece within the range of the rectangular groove. Then, the magnetic force of the magnets on both sides of the reference angle adsorbs the workpiece through the positioning surface, enabling the workpiece to be quickly and accurately positioned with the reference angle as the base point. There is no need for manual adjustment of each workpiece, and multiple rectangular grooves are provided on the fixing table, allowing synchronous positioning and processing of multiple workpieces, greatly reducing the labor intensity of workers and the processing time of a single workpiece, significantly improving production efficiency, and being able to adapt to large-scale mass production.

[0008] 2. In this solution, each workpiece uses the reference point as the positioning base point, ensuring that the positioning accuracy of each workpiece is consistent, thereby guaranteeing the processing accuracy and quality uniformity during batch processing of workpieces, effectively reducing the defective rate, and reducing cost losses.

[0009] 3. In this solution, each workpiece is fixed in the rectangular groove by a magnet with the reference point as the base point, achieving magnetic adsorption and clamping while positioning. Compared with the existing mechanical vise or clamp plate fixation, the magnetic adsorption fixation by the magnet does not directly contact and squeeze the workpiece, effectively avoiding deformation of the workpiece due to pressure and ensuring the quality of the workpiece finished product.

[0010] 4. In this solution, each rectangular groove is provided with a reference angle and the size of the rectangular groove is larger than that of the workpiece. In specific production, it can be applied to the processing of a variety of thin-walled rectangular workpieces with different sizes, expanding the processing range of the fixing tooling, enhancing the versatility and economy of the fixing tooling, and also eliminating the need to manufacture too many fixing toolings with different sizes, reducing processing costs.

[0011] Furthermore, the fixing table is made of a material with magnetic permeability.

[0012] The fixing table having magnetic permeability is beneficial to the penetration of the magnetic force of the magnet, enhancing the magnetic adsorption strength of the fixing table and the magnet on the workpiece, and enabling the workpiece to be more stably fixed in the rectangular groove.

[0013] Furthermore, a magnet installation groove is opened at the bottom of the rectangular groove near the reference angle.

[0014] The above setting enables the side and bottom of the workpiece to be subjected to magnetic adsorption, enabling faster and more stable positioning and adsorption fixation of the workpiece, facilitating subsequent processing.

[0015] Furthermore, a powerful magnetic disk is connected to the bottom of the fixing table.

[0016] The powerful magnetic disk cooperates with the magnet in the magnet installation groove to strengthen the magnetic adsorption fixation of the workpiece, ensuring the stability of the workpiece during the processing, and thereby improving the processing accuracy of the workpiece.

[0017] Furthermore, a threaded hole is opened at the bottom of the magnet installation groove, and a bolt for fixing the magnet is installed in the threaded hole.

[0018] The above setting makes the magnet more firmly fixed in the magnet mounting groove, preventing the magnet from shaking and reducing the adsorption and clamping accuracy of the workpiece.

[0019] Furthermore, chip removal through holes communicating with the chip removal groove are formed in the powerful magnetic disk.

[0020] The above setting facilitates the timely discharge of chips generated during machining, avoiding affecting the subsequent machining of the workpiece, and the chip removal through holes serve as retraction grooves, effectively preventing the drill bit or laser from damaging the powerful magnetic disk during drilling or laser cutting, which affects the fixing strength of the powerful magnetic disk for the workpiece.

[0021] Furthermore, arc-shaped grooves are formed at two top corners of the positioning surface on one side of the short side of the rectangular groove, and the arc-shaped grooves communicate with the rectangular groove.

[0022] The above arc-shaped grooves leave a buffer space for the end of the workpiece, effectively preventing the top corner of the workpiece adsorbed by the magnet from hitting the fixing table, which affects the appearance structure of the workpiece and the subsequent installation accuracy.

[0023] Furthermore, the minimum distance between the chip removal groove and the side of the rectangular groove parallel to it is not less than 2 mm.

[0024] The above setting is to ensure that both ends of the machining area of the workpiece are supported during machining, preventing the workpiece from warping during machining and affecting the machining quality. Description of the Drawings

[0029] The following is a more detailed description through specific embodiments:

[0030] The reference numerals in the accompanying drawings of the specification include: fixing table 1, rectangular groove 2, reference angle 3, positioning surface 4, magnet mounting groove 5, threaded hole 6, chip removal groove 7, arc-shaped groove 8, powerful magnetic disk 9, mounting block 10, fastening screw 11, chip removal through hole 12.

[0031] Embodiment 1

[0032] Basically as shown in the attached Figure 1 、 Figure 2Shown: A fixing tooling for rapid positioning of workpieces, including a fixing table 1 made of a material with magnetic permeability. A plurality of rectangular grooves 2 for accommodating workpieces are evenly arranged on the fixing table 1. In this embodiment, 9 rectangular grooves 2 are arranged in a 3×3 array on the fixing table 1. The size of the rectangular groove 2 is larger than that of the workpiece. One vertex angle at the same position of each rectangular groove 2 is a reference angle 3. In this example, the upper right corner of each rectangular groove 2 is the reference angle 3. The two side surfaces connected by the reference angle 3 are positioning surfaces 4. The fixing table 1 is provided with magnet mounting grooves 5 on both sides of each reference angle 3. The magnet mounting grooves 5 are parallel to the positioning surfaces 4. Magnets (not shown in the figure) are installed in the magnet mounting grooves 5. The magnets adsorb the workpiece to the positioning surfaces 4. The length of the magnet mounting groove 5 parallel to the short side of the rectangular groove 3 is equal to the length of the positioning surface 4, and the length of the magnet mounting groove 5 parallel to the long side of the rectangular groove 3 is greater than 1 / 2 of the length of the positioning surface 4, so as to ensure the stable adsorption of the magnet to the workpiece; preferably, magnet mounting grooves are also provided at the bottom of the rectangular groove 2 near the reference angle 3. Such a setting enables the side and bottom of the workpiece to be magnetically adsorbed, and can more quickly and stably realize the positioning and adsorption fixation of the workpiece, facilitating subsequent processing. Threaded holes 6 are also provided in the magnet fixing grooves, and bolts (not shown in the figure) are installed in the threaded holes 6 to fasten the magnets in the magnet mounting grooves 5, preventing the magnets from shaking and reducing the adsorption and clamping accuracy of the workpiece.

[0033] A longitudinally penetrating chip removal groove 7 is provided on the fixing table 1, and the chip removal groove 7 is directly below the machining position of the workpiece. The specific position of the chip removal groove 7 is determined according to the machining position of the workpiece. The chip removal groove 7 not only facilitates the timely discharge of chips generated during machining, avoiding affecting the subsequent machining of workpieces, but also serves as a relief groove, effectively preventing the drill bit or laser from damaging the fixing tooling during drilling or laser cutting, affecting the fixing strength of the workpiece. The minimum distance between the chip removal groove 7 and the side of the rectangular groove 2 parallel to it is not less than 2 mm. In this embodiment, the distance between the chip removal groove 7 and the side of the rectangular groove 2 is 2 mm, and the width of the chip removal groove 7 is 10 mm, so as to ensure that both ends of the machining area of the workpiece have support during machining, preventing the workpiece from warping during machining and affecting the machining quality.

[0034] Preferably, arc-shaped grooves 8 are provided at the two vertex angles of the positioning surface 4 on the short side of the rectangular groove 2. The arc-shaped grooves 8 communicate with the rectangular groove 2. The arc-shaped grooves 8 leave a buffer space for the end of the workpiece, effectively preventing the vertex angle of the magnet-adsorbed workpiece from hitting the fixing table 1, affecting the appearance structure of the workpiece and the subsequent installation accuracy.

[0035] The specific implementation process is as follows:

[0036] During specific operation, the fixed table 1 is fixed on a bracket or a frame close to the processing equipment. Then, the worker sequentially places the thin-walled rectangular workpieces into the rectangular grooves 2. When placing the workpieces, there is no need for excessive adjustment, and only ensuring that the workpieces are within the rectangular grooves 2 is required. Then, the magnets in the magnet mounting grooves 5 magnetically attract the workpieces. Under the guidance of the magnetic force, the workpieces closely adhere to the positioning surfaces 4 in the rectangular grooves 2, achieving positioning and magnetic adsorption fixation. Then, the processing equipment drills or cuts the workpieces mechanically. After the processing is completed, the worker collects the workpieces in the rectangular grooves 2, and then spreads the workpieces to be processed again, repeating the above processing operations.

[0037] In this solution, the worker only needs to place the thin-walled rectangular workpieces within the range of the rectangular grooves 2. Then, the magnets attract the workpieces, enabling the workpieces to quickly and accurately complete positioning with the reference angle 3 as the base point. There is no need for manual adjustment of each workpiece individually. Moreover, there are multiple rectangular grooves 2 on the fixed table 1, which can realize synchronous positioning and processing of multiple workpieces, greatly reducing the labor intensity of the worker and the processing time of a single workpiece, significantly improving the production efficiency, and being able to adapt to large-scale mass production. Secondly, in this solution, each workpiece uses the reference angle 3 as the positioning base point, ensuring that the positioning accuracy of each workpiece is consistent, thereby guaranteeing the processing accuracy and quality uniformity during batch processing of the workpieces, effectively reducing the defective rate, and reducing cost losses. Furthermore, magnetic adsorption clamping is achieved during positioning. Compared with the existing mechanical vises or clamping plates for fixation, the magnetic adsorption fixation by the magnets does not directly contact and squeeze the workpieces, effectively avoiding deformation of the workpieces due to pressure and ensuring the quality of the workpiece products.

[0038] Embodiment 2

[0039] As Figure 3 、 Figure 4 shown, in this embodiment, a powerful magnetic disk 9 is provided at the bottom of the fixed table 1. Installation blocks 10 are symmetrically connected to both sides of the fixed block. Threaded holes 6 are opened in the installation blocks 10, and fastening screws 11 are installed in the threaded holes 6 to fix the fixed table 1 and the powerful magnetic disk 9 together. The powerful magnetic disk 9 is an electrically controlled magnetic disk. When powered on, the powerful magnetic disk 9 generates a strong magnetic force to cooperate with the magnets in the magnet mounting grooves 5 to magnetically adsorb and fix the workpieces in the rectangular grooves 2, improving the stability of the workpieces in the rectangular grooves 2 and ensuring the processing accuracy and quality of the workpieces. After the processing is completed, the powerful magnetic disk 9 is powered off, and the worker takes out the workpieces. Longitudinally penetrating chip removal through holes 12 are opened on the powerful magnetic disk 9, and the chip removal through holes 12 are communicated with the chip removal grooves 7 on the fixed table 1, facilitating the timely discharge of the chips generated during processing. At the same time, the chip removal through holes 12 serve as relief grooves, which can effectively prevent the drill bit or laser from damaging the powerful magnetic disk 9 during drilling or laser cutting, affecting the fixing strength of the powerful magnetic disk 9 for the workpieces.
