Description

Technical Field

[0001] The present invention relates to the technical field of jigs, and particularly to a special jig for metal detection and a detection device. Background Art

[0002] In metal detection and related precision operations, as a key auxiliary device, the jig plays a crucial role in the positioning, fixing, and stability of workpieces; especially in detection scenarios with high-precision requirements, the jig needs to have high adaptability, high reliability, and convenient operation to ensure the stable position of the workpiece and operation efficiency during the detection process. Although traditional jigs can achieve basic fixing functions, they have certain limitations in actual use, such as complex structures, cumbersome installations, and insufficient adaptability to workpieces.

[0003] At present, most jigs on the market fix workpieces by using a single threaded connection or mechanical clamping method. Such designs are prone to being affected by vibrations or workpiece size deviations during use, resulting in unstable clamping effects of workpieces; in addition, for scenarios where workpieces need to be frequently replaced, due to the need for complex rotational docking of threaded connectors, the adjustment difficulty is relatively high, reducing the operation efficiency.

[0004] In addition, in complex environments, jigs often need to be installed on slides or other equipment, which puts higher requirements on the seismic resistance and stability of jigs; after traditional jigs are installed, due to the large contact area with slides or support components, they are easily interfered by external vibrations, resulting in displacement or loosening of the clamped workpieces; in metal detection scenarios, the use of precision equipment has extremely high requirements for the position of workpieces, and any minor deviation may have a significant impact on the detection results.

[0005] At the same time, existing metal detection devices may be unstable when carrying heavy loads, resulting in deviations in detection accuracy and detection areas. In addition, although some devices have an automatic adjustment function, due to the lack of precise limit devices and support systems, they often cannot quickly adjust or position the detector in different working environments, thus affecting the accuracy and efficiency of the detection effect. Summary of the Invention

[0045] A special fixture for metal detection of the present invention has the following beneficial effects:

Especially, it can still work stably in a vibrating environment.

[0047] 2. The V-shaped groove can naturally guide the workpiece to the center position at the bottom of the groove, and high-precision positioning can be completed without additional adjustment, which is suitable for circular, polygonal, tubular, and conical metal workpieces.

[0060] In order to clearly understand the technical means, creative features, achieved objectives and effects of the present invention, the present invention will be further described below in conjunction with specific embodiments.

[0061] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "lateral", "longitudinal", "end", "edge", "side wall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0062] The present application proposes a special fixture for metal detection, which is specifically as follows:

[0063] Reference can be made to Figure 1-2 , the present application mainly consists of a support base 1, a connecting top shaft 2 detachably provided on the support base 1 through bolts, V-shaped grooves 3 and trapezoidal grooves 4 opened on the support base 1 and the connecting top shaft 2, a threaded shaft 5 threadedly connected to the connecting top shaft 2, and a positioning member 6 clamped and fixed by two threaded shafts 5. Through the design of this fixture, multiple advantages such as high stability, high adaptability, convenient operation and strong clamping force are achieved, and it is particularly suitable for metal detection scenarios that require high-precision clamping.

[0064] Reference can be made to Figure 1-4 , both the support base 1 and the connecting top shaft 2 are in the shape of an I-beam, which improves the bearing capacity and anti-deformation ability and meets the metal detection requirements under complex environments; the heights of the support base 1 and the connecting top shaft 2 are not limited, and it is only necessary to adapt to the required support height after connection.

[0065] Reference can be made to Figure 1-4 , the structures of the support base 1 and the connecting top shaft 2 are roughly the same, and it has a structure connected to an external slideway more than the connecting top shaft 2; a V-shaped groove 3 and a trapezoidal groove 4 are provided on both the support base 1 and the connecting top shaft 2, and the V-shaped groove 3 and the trapezoidal groove 4 are located on the symmetrical sides in both structures.

[0066] On the support base 1, the V-shaped groove 3 can disperse pressure and improve stability during the operation of the fixture; while the trapezoidal groove 4 on the support base 1 can reduce the contact area between the support base 1 and the external slideway. One side of the support base 1 with the trapezoidal groove 4 protrudes outwardly with a square shaft 11. There are two square shafts 11. Through the two square shafts 11, a rear connection relationship is formed between the support base 1 and the external slideway. The connection spacing between the two square shafts 11 is greater than the trapezoidal groove 4. Therefore, the bottom surfaces of the support base 1 on both sides of the trapezoidal groove 4 will be pressed tightly against the external slideway. At this time, through the design of the trapezoidal groove 4, a gap is formed between them, reducing the contact area with the external slideway. Thus, the vibration transmitted from the external slideway to the fixture can be reduced, further improving the stability of the fixture during operation;

[0067] Furthermore, after adjusting the position of the external slideway, through the clamping screw 12 provided on the support base 1 corresponding to the square shaft 11, the support base 1 is firmly connected to the external slideway, not easily loosened, increasing the stability of the overall structure.

[0068] For reference Figure 4 Refer to, and in the connecting top shaft 2, through the design of the V-shaped groove 3, the workpiece can be automatically guided to the center position at the bottom of the groove, suitable for clamping circular or polygonal workpieces, such as round bars, tubular or conical metal parts, ensuring its accurate position; at the same time, the inclined surface of the V-shaped groove provides lateral restraint, effectively preventing the possibility of the workpiece sliding laterally in the fixture; the trapezoidal groove 4 provided in the connecting top shaft 2 is arranged corresponding to the V-shaped groove 3 on the support base 1 up and down. The diameter of the trapezoidal groove 4 is larger than that of the V-shaped groove 3, so that the surface where the connecting top shaft 2 exerts downward force can all be supported on the upper surface of the support base 1; contributing to increasing the stability of the connection. Secondly, in the connection between the connecting top shaft 2 and the support base 1, four long screws are used for fixation. The bolt penetrates through the upper surface of the connecting top shaft 2 and is connected to the support base 1.

[0069] For reference Figure 1 、 Figure 2 And Figure 5-6 After the workpiece is placed in the V-shaped groove 3 of the connecting top shaft 2, it is fixed by the cooperation between the threaded shaft 5 and the positioning member 6 on the upper side, and the workpiece can be firmly fixed for subsequent detection work.

[0070] Among them, the threaded shaft 5 includes a threaded rod 51 and a screw top 52; the threaded rod 51 is detachably connected to the connecting top shaft 2 by threads, and the screw top 52 is fixedly connected to the end of the threaded rod 51 far from the connection with the connecting top shaft 2; during use, the threaded rod 51 can be adjusted up and down to a suitable position first, and then one side of the threaded rod 51 is clamped to the positioning member 6, and by rotating the positioning member 6, the other end of the positioning member 6 is clamped to the threaded rod 51 on the symmetric side. At this time, the workpiece is located between the positioning member 6 and the V-shaped groove 3 of the connecting top shaft 2, and by adjusting the threaded rod 51 to move downward again, the positioning member 6 can be fastened at the upper end of the workpiece.

[0071] In order to achieve the cooperation between the positioning member 6 and the two threaded shafts 5 and further optimize the positioning member 6, the positioning member 6 is provided with a first positioning shaft 61, a convex shaft 62 and a second positioning shaft 63. The convex shaft 62 is arranged in the middle of the connection between the first positioning shaft 61 and the second positioning shaft 63. The first positioning shaft 61 and the second positioning shaft 63 are horizontally arranged to keep the heights of both ends the same when contacting the two threaded rods 51, which promotes the stable progress of the subsequent clamping work; the middle part of the convex shaft 62 bulges outward toward the side away from the connecting top shaft 2 and is in an inverted V shape. This shape design increases the multi-directional restriction on the workpiece and prevents the workpiece from shifting.

[0072] Furthermore, a clamping groove 64 is provided on both the first positioning shaft 61 and the second positioning shaft 63. The two clamping grooves 64 are arranged in a cross orientation. This design can first form a clamping connection between one clamping groove 64 and one threaded rod 51, and then rotate to make the other clamping groove 64 engage with the other threaded rod 51; at this time, the positioning member 6 will stably form a connection with the two threaded rods 51. When the positioning member 6 is moved left, right, forward, or backward at this time, the positioning member 6 will stably work on the connecting top shaft 2.

[0073] Specifically, the clamping groove 64 is in a U shape, and the opening orientations of the two groups of clamping grooves 64 are different (reference can be made to Figure 5 ), but the sizes are the same, and they are all adapted to the threaded rod 51; the diameter of the screw top 52 is set to be larger than that of the threaded rod 51 and larger than the clamping groove 64. Therefore, during the process of driving the threaded rod 51 to move downward by screw rotation, the screw top 52 will be urged to press against the positioning member 6 and move downward synchronously until the positioning member 6 presses against the workpiece. At this time, the stable work on the upper and lower sides is completed, and the positioning member 6 is positioned in the front, back, left, and right directions by the above-mentioned threaded rod 51. At this time, the positioning member 6 will be completely fixed on the upper side of the connecting top shaft 2 to clamp the workpiece and will not move in any direction again.

[0074] The positioning member 6 does not have a direct threaded connection relationship with the threaded shaft 5, avoiding the possible rotation docking problem in threaded connection, reducing the use difficulty, and being particularly suitable for scenarios where workpieces are frequently replaced or the fixture is adjusted. Therefore, it is more convenient to replace the positioning member 6 with other connecting members in different scenarios.

[0075] In the present invention, the working steps of the device are as follows:

[0076] 1. First, install the support base 1 on the external slideway, adjust the position, and then fix it with the clamping screw 12. When supporting a workpiece, at least two support bases 1 installed on the external slideway are required;

[0077] 2. Secondly, install and fix the side of the connecting jackshaft 2 with the trapezoidal groove 4 facing the support base 1 through bolts. Subsequently, place the workpiece into the V-shaped groove 3 of the connecting jackshaft 2;

[0078] 3. Then, thread the two threaded shafts 5 onto the connecting jackshaft 2, and snap the positioning member 6 onto one threaded shaft 5. By rotating, snap the other end of the positioning member 6 onto the other threaded shaft 5. At this time, the positioning member 6 can be positioned on the threaded shaft 5 without loosening left, right, forward, or backward;

[0079] 4. Finally, move downward through the threaded shaft 5 to make the positioning member 6 firmly contact the workpiece.

[0080] Furthermore, the metal detection device in an embodiment of the present invention is specifically as follows:

[0081] For reference Figure 7 , the base 701 is used to disperse and bear the load. The base 701 is composed of multiple groups of four-groove guide beams spliced together. The four-groove guide beam itself has strong structural rigidity. After being spliced into the base, it can better disperse and bear the load, improve the overall stability and anti-deformation ability, and in particular, enable the base 701 to have the ability to carry heavier equipment for work.

[0082] Furthermore, on the surface of multiple groups of four-groove guides, there are multiple groups of sliding grooves, which are matched and connected with the subsequent connected equipment.

[0083] For reference Figure 7 , the linear guide 702 is positioned and installed on the base 701 according to the setting position of the sliding groove. The linear guide 702 adopts an electric linear guide, which is a common technology in this field and will not be elaborated in this application. At the same time, in order to make the linear guide 702 cooperate with the sliding groove on the base 701 during installation, multiple groups of connecting members 7021 are further provided on both sides of the linear guide 702. Through the setting of the connecting members 7021, the linear guide 702 is stably installed on the base 1;

[0084] Specifically, the connecting member 7021 includes a positioning plate 211 and a positioning screw 212. The positioning plate 211 is installed on the linear guide 702 through bolts. When the positioning plate 211 is installed on the linear guide 702, its lower surface is flush with the lower surface of the linear guide 702, and at this time, the bottom is in a parallel state. The positioning screw 212 is correspondingly arranged according to the sliding groove provided on the lower side of the positioning plate 211. Thus, after installation, the installation work of the connecting member 7021 can be completed through the sliding groove and the positioning screw 212. Further, the state of left and right shaking is also prevented through the limitation of the sliding groove, making it more stable after installation.

[0085] For reference Figure 7-8, a first hand-operated cylinder 703 is arranged on the linear guide rail 702 and can perform linear motion along the direction of the linear guide rail 702; thus, when the linear guide rail 702 starts to work, it will drive the first hand-operated cylinder 703 to perform horizontal linear motion; and the first hand-operated cylinder 703 and the linear guide rail 702 are arranged in a cross shape. Then, when the second hand-operated cylinder 704 is arranged on the first hand-operated cylinder 703, the first hand-operated cylinder 703 can be used to promote the second hand-operated cylinder 704 to perform horizontal linear motion, so as to achieve the adjustment work of up, down, left, and right; to meet the required design requirements, the second hand-operated cylinder 704 is also arranged in a cross shape with the first hand-operated cylinder 703; then, the fixing plate 5 arranged on the second hand-operated cylinder 704 will be arranged in parallel with the first hand-operated cylinder 703 in the front-rear position. Then, when the second hand-operated cylinder 704 works, it can drive the fixing plate 705 to perform front-rear motion;

[0086] Through the above settings, the position changes in the front-rear, left-right, and up-down directions can be realized, which is more conducive to adjusting in cooperation with the size of the material when detecting different metal materials subsequently.

[0087] It should be noted that the first hand-operated cylinder 703 is installed on the slider of the linear guide rail 702 to realize the moving work, the second hand-operated cylinder 704 is installed on the slider of the first hand-operated cylinder 703 to realize the moving work, and the fixing plate 705 is installed on the slider of the second hand-operated cylinder 704 to realize the moving work; both the first hand-operated cylinder 703 and the second hand-operated cylinder 704 are relatively mature existing technologies, which will not be elaborated in this application.

[0088] For reference Figure 8-10 , the length of the fixing plate 705 is greater than the length of the slider of the second hand-operated cylinder 704. The support assembly 706 is installed at a position on the surface of the fixing plate 5 that has no contact with the second hand-operated cylinder 704, which is more conducive to the installation and disassembly of the support assembly 706; when it is necessary for the support assembly 706 to carry the detector 707 of different sizes to work, it can be disassembled and replaced with a more suitable-sized support assembly 706 to work.

[0089] For reference Figure 9-10 , when the change in the size of the detector 707 adopted is relatively small, then it is relatively wasteful to replace the entire support assembly 706. Based on this problem in this application, a further design is made. The support assembly 706 is set to include a support plate 7061, a first clamping plate 7062, and a second clamping plate 7063; the support plate 7061 is in an L shape, one end of which is detachably connected to the fixing plate 705. The first clamping plate 7062 is in an L shape and is arranged in contact with the bottom surface of the support plate 7061. The second clamping plate 7063 is in an L shape and is symmetrically arranged with the first clamping plate 7062, and the lower surface of the second clamping plate 7063 is arranged on the first clamping plate 7062;

[0090] A fixing screw 70631 is provided in the middle of the bottom joint of the second clamping plate 7063 and the first clamping plate 7062. Through the fixing screw 70631, the second clamping plate 7063 and the first clamping plate 7062 can be connected and fixed together. When they are not connected by the fixing screw 70631, the second clamping plate 7063 can be adjusted on the first clamping plate 7062 to change the connection gap between the two, and this gap is adapted to the width of the detector 707. Thus, by adjusting back and forth, the upper parts of the first clamping plate 7062 and the second clamping plate 7063 clamp the detector 707.

[0091] Furthermore, considering that the detector 707 may shake after rubbing against the inner surfaces of the first clamping plate 7062 and the second clamping plate 7063, a plurality of tightening screws 70632 are provided on one side of the second clamping plate 7063. After installing the fixing screw 70631, the tightening screws 70632 can be further used for fixing work to increase the resistance and reduce the situation that the detector 707 shakes during the detection process due to the decrease in resistance caused by friction.

[0092] The above solves the fixation of the detector 707 when it is located in the support assembly 706. At the same time, it is also considered that the detector 707 may shake in the support assembly 706 during installation, resulting in a deviation between the fixed position of the detector 707 and the expected position. Therefore, clamping screws 70621 are provided. There are at least two groups of clamping screws 70621, which are installed on the first clamping plate 7062 on both sides of the detector 707. Among them, the clamping screws 70621 with nuts of at least 2 - 3 cm are used to position the detector 707 by tightening the nuts against both sides, thus facilitating subsequent work operations.

[0093] Further explanation, the clamping screw 70621 and one of the existing screws are of a kind. According to the common existing screws, they are all composed of a nut and a screw rod, which is a very mature existing technology.

[0094] To further reduce the parts used in the structure, the clamping screw 70621 penetrates through the first clamping plate 7062 and the support plate 7061 to form a connection. Thus, after installation, the clamping screw 70621 can achieve the effects of connecting the first clamping plate 7062 and the support plate 7061 and limiting the detector 707; it also promotes the detachable connection relationship between the first clamping plate 7062 and the support plate 7061.

[0095] For reference Figure 7 , there is no limitation on the detector 707. Different models of equipment can be selected according to the actual required instrument, as long as it works in the support assembly 6.

[0096] For reference Figure 1And Figure 7 There are at least two sets of fixtures 8, which are arranged on the base 1 on both sides of the detector 7. The fixtures 8 are adaptively connected to the sliding grooves on the base 1 and are horizontally arranged in the front and back with the linear guide rail 2. Through the mutual adjustment of the linear guide rail 2, the first hand-operated air cylinder 3 and the second hand-operated air cylinder 4, the detector 7 can be adjusted to a position corresponding to the front and back of the fixture 8. At this time, only the metal material needs to be inserted into the detector 7, and both ends are clamped and fixed by the fixture 8. At this time, the first hand-operated air cylinder 3 and the second hand-operated air cylinder 4 do not move, and only the linear guide rail 2 needs to be controlled to make a linear reciprocating motion. Through the control of the linear guide rail 2, the detector 7 is controlled to reciprocate and perform detection work on the metal material;

[0097] Furthermore, the size and height of the fixture 8 are adjusted according to the surface of the detector 7, and can be adjusted according to the changes of the detector 7 or the detection material, so as to adapt to the requirements of the current scenario.

[0098] In the present invention, the working steps of the device are as follows:

[0099] 1. First, a firm base 701 is built by multiple four-groove guide beams. The linear guide rail 702 and the fixture 708 are arranged in parallel on the base 701, and the rest of the structures are installed on the linear guide rail 702 as required;

[0100] 2. Secondly, the detector 707 adapted to the requirements of the scenario is installed on the support assembly 706, and the position of the detector 707 is changed by the movement of the first hand-operated air cylinder 703 and the second hand-operated air cylinder 704;

[0101] 3. Then, the detector 707 is adjusted to be on the same horizontal line as the clamping position of the fixture 708 through adjustment;

[0102] 4. Finally, the metal material is inserted into the middle of the detector 707, and both ends are fixed by two sets of fixtures 708 to reduce the influence of the shaking of the fixture 708 on the detection. After fixing, the linear guide rail 702 moves to make the detector 707 reciprocate along the metal material, and then the detection situation is obtained.

[0103] In summary, the metal detection fixture and device of the present invention not only increase the bearing capacity during the metal detection process, but also effectively disperse the pressure, improve the overall stability, and further can effectively improve the stability, accuracy and flexibility of metal detection, especially can still work stably in a vibration environment.
