Description

Technical Field

[0001] This invention relates to the field of auxiliary tooling technology for electronic assembly, and in particular to a detachable welding bracket suitable for electronic assembly and maintenance. Background Technology

[0002] In the diagnostic system of the tokamak fusion experimental device, equipment such as magnetic probes, fiber optic interferometers, and Langmuir probes rely on a large number of precision thin cables to complete signal transmission. These cables are thin in diameter and densely arranged, and both assembly and subsequent circuit breakage repair require manual welding operations.

[0003] Existing commercially available welding clamping fixtures have the following inherent defects: First, they have a single installation mode, only supporting clamping on a table edge or only supporting flat floor placement. They cannot be used when the size of the experimental site table is limited or there is no clamping edge, thus narrowing the applicable scenarios. Second, the clamping structure is fixed, with only a single unidirectional pressure plate. It is impossible to independently adjust the horizontal and vertical clamping space, making it difficult to clamp multiple cables of different diameters at the same time. The clamping process is prone to cable twisting and displacement, affecting welding accuracy. Third, the supporting column is a smooth cylindrical structure, and the height adjustment has no segmented interlocking structure, making locking difficult. The bolts are prone to slippage, the support has poor stability after the height is fixed, and it cannot adapt to the operating posture of different operators; fourth, the tooling is a bent one-piece molding structure, and the parts cannot be disassembled for transportation and storage. The fusion laboratory has multiple devices coexisting and the space is compact. The one-piece tooling occupies a lot of space and is inconvenient to transport; fifth, the depth and width of the clamping slot are fixed, which cannot be compatible with two different types of welding workpieces: small circuit boards and multiple bundles of parallel cables. Changing workpieces requires changing the entire set of tooling, which results in low experimental efficiency. Therefore, this application proposes a detachable welding support suitable for electronic assembly and maintenance. Summary of the Invention

[0009] Optionally, the bottom of one side and the sidewall of the other side of the adjustable clamping head are symmetrically provided with trapezoidal sliding grooves. A movable upright plate is slidably connected to the bottom of the adjustable clamping head. The movable upright plate is a rectangular plate. Square insertion protrusions are integrally formed at the bottom of both ends of the movable upright plate. The square insertion protrusions are engaged in a set of trapezoidal sliding grooves on the bottom of one side of the adjustable clamping head and are slidably connected with the set of trapezoidal sliding grooves with a clearance fit. A transverse screw hole is provided on the sidewall of the adjustable clamping head corresponding to the position of the movable upright plate. A third fastening bolt is screwed into the transverse screw hole. The end of the third fastening bolt abuts against the surface of the movable upright plate to achieve positioning and locking.

[0010] Optionally, a movable pressure plate is slidably connected to the other side of the adjustable clamping head. The movable pressure plate is a rectangular plate with square insertion protrusions integrally formed at the bottom of both ends. The square insertion protrusions are engaged in another set of trapezoidal sliding grooves on the other side wall of the adjustable clamping head and are slidably connected with the other set of trapezoidal sliding grooves with clearance fit. A vertical screw hole is opened at the top of the adjustable clamping head corresponding to the position of the movable pressure plate. A fourth fastening bolt is screwed into the vertical screw hole at the top of the adjustable clamping head. The end of the fourth fastening bolt abuts against the surface of the movable pressure plate to achieve positioning and locking.

[0011] Optionally, the third, fourth, first, second, and fifth fastening bolts have the same structure, with a transverse through hole at one end of each bolt, a cylindrical handle inserted into the through hole, and a frustum pad fixedly connected to the other end of the bolt.

[0012] Optionally, four elongated grooves are formed along the axial direction on the outer wall of the supporting column, and the four elongated grooves are evenly distributed around the periphery of the supporting column.

[0013] Optionally, the heavy-duty base is a solid cuboid made of metal, the depth of the screw hole on the top surface of the heavy-duty base is less than the height of the heavy-duty base itself, and the inner diameter of the screw hole matches the external thread at the bottom of the support column.

[0016] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0017] This invention simultaneously sets up a heavy-duty base for ground support and a desktop clamping component for edge clamping. When there is no workbench clamping edge, the heavy-duty metal base is placed flat on any plane to provide support. When a workbench is provided, the desktop clamping component is slid to the corresponding height and then locked. The edge of the workbench is clamped by pressing down the fifth fastening bolt. One set of brackets can be adapted to all work scenarios such as laboratories, maintenance rooms, and temporary workbenches, solving the problem of the single installation mode of existing tooling.

[0018] The adjustable clamping head of this invention has two sets of independent trapezoidal sliding grooves inside, which are respectively fitted with a movable upright plate and a movable pressure plate. The two plates slide independently along their respective tracks, controlling the longitudinal and lateral clamping spaces respectively. It can simultaneously clamp multiple cables of different diameters and small circuit boards. After clamping, the workpiece does not twist or slip, which greatly improves the precision of precision cable welding.

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0028] Example 1

[0029] like Figure 1 As shown, this invention proposes a detachable welding bracket suitable for electronic assembly and repair, comprising an adjustable clamping head 2, a third fastening bolt 3, a fourth fastening bolt 4, a movable pressure plate 5, a movable upright plate 6, a support column 7, a desktop clamping assembly 8, a fifth fastening bolt 9, a second fastening bolt 10, a heavy-duty base 11, and a first fastening bolt 12, all assembled together. The support column 7 is a vertical rod component, with an integrally machined external thread on the outer wall of its bottom end. The heavy-duty base 11 is a solid metal cuboid, with a vertically protruding screw hole on its top surface matching the external thread of the support column 7. The depth of the screw hole is less than the overall height of the heavy-duty base 11. During assembly, the bottom end of the support column 7 is vertically screwed into the screw hole on the top surface of the heavy-duty base 11. The screw thread allows for detachable fixing of the support column 7 and the heavy-duty base 11. The combination of the two forms a support unit for the bracket, with the solid metal base providing counterweight to prevent tipping or displacement when placed on a flat surface. Four equal-length grooves are opened on the outer wall of the support column 7 along the axial direction. The four grooves are evenly distributed around the support column 7. The grooves are used to engage and limit the engagement of the frustum pads at the ends of each fastening bolt, so as to achieve stable locking at any height.

[0030] The desktop clamping assembly 8 is a frame-shaped kit with a through-hole in the center. During assembly, the desktop clamping assembly 8 is fitted onto the lower part of the support column 7 through the central hole from the top. The desktop clamping assembly 8 can slide freely up and down along the axis of the support column 7 to adjust the installation height. A horizontal threaded hole is opened on the side wall of the desktop clamping assembly 8. A second fastening bolt 10 is screwed into the horizontal threaded hole. The second fastening bolt 10 is horizontally inserted into the assembly. The truncated cone pad at the end of the bolt abuts against the outer wall of the support column 7. The truncated cone pad is embedded in the long groove on the outer wall of the support column 7. The desktop clamping assembly 8 is positioned and locked at any height of the support column 7 by the engagement of the groove, which restricts the upward and downward movement of the assembly. A vertical screw hole is vertically opened on the top surface of the desktop clamping assembly 8. The fifth fastening bolt 9 is vertically screwed into the vertical screw hole. The fifth fastening bolt 9 passes through the desktop clamping assembly 8 in the vertical direction, and the lower end of the bolt extends downward out of the bottom surface of the desktop clamping assembly 8. When it is necessary to clamp the edge of the worktable, the desktop clamping assembly 8 is moved down to the top of the worktable, and the fifth fastening bolt 9 is rotated to feed downward. The lower end of the bolt presses against the top surface of the worktable, forming an upper and lower clamping structure with the bottom surface of the desktop clamping assembly 8, fixing the whole machine to the edge of the worktable, and completing the table edge clamping mode assembly.

[0031] The adjustable clamping head 2 is an integral rectangular frame. Two sets of independent trapezoidal track grooves are symmetrically arranged within the frame's inner cavity. Both sets of trapezoidal sliding grooves have a uniform trapezoidal cross-section with an upper base of 5mm, a lower base of 10mm, and a height of 5mm. The lower edge of the groove is fixedly positioned 5mm from the bottom edge of the adjustable clamping head 2 and 5mm from its side edge. The side wall of the adjustable clamping head 2 has three independent horizontal screw holes and one vertical screw hole: one horizontal screw hole matches the first fastening bolt 12, one horizontal screw hole matches the third fastening bolt 3, and one vertical screw hole matches the fourth fastening bolt 4. A through circular hole is provided at the bottom of the frame. The top of the supporting column 7 passes through this circular hole from bottom to top, allowing the adjustable clamping head 2 to be fitted entirely onto the upper part of the supporting column 7. The clamping head can slide up and down along the column to adjust the operating height. The first fastening bolt 12 is inserted through the transverse screw hole on the side wall of the adjustable clamping head 2. The truncated block at the end of the bolt presses inward against the outer wall of the support column 7. The block is embedded in the long groove of the column to lock the height of the adjustable clamping head 2 and limit the vertical displacement of the clamping head.

[0032] The adjustable clamping head 2 has a first set of trapezoidal sliding grooves at the bottom of its inner cavity. The movable upright plate 6 is a rectangular plate component with square insertion protrusions integrally formed at both ends of the plate. During assembly, the two square insertion protrusions are inserted into the trapezoidal sliding grooves at the bottom, with a clearance fit between the square protrusions and the inner wall of the trapezoidal groove, allowing the movable upright plate 6 to slide horizontally back and forth along the trapezoidal groove to adjust the longitudinal clamping depth. A transverse screw hole is opened on the side wall of the adjustable clamping head 2 corresponding to the position of the movable upright plate 6. A third fastening bolt 3 is screwed into the screw hole. Rotating the third fastening bolt 3 to feed inward causes the frustum pad at the end of the bolt to press against and tighten the outer surface of the movable upright plate 6. The sliding position of the movable upright plate 6 is locked by friction, thus completing the fixation of the longitudinal clamping dimension.

[0033] The adjustable clamping head 2 has a second set of trapezoidal sliding grooves arranged on the inner wall of its cavity. The movable pressure plate 5 is a rectangular plate component with square insertion protrusions integrally formed at both ends of the plate. During assembly, the two square insertion protrusions are inserted into the trapezoidal sliding grooves on the side wall, with a clearance fit between the square protrusions and the inner wall of the trapezoidal groove, allowing the movable pressure plate 5 to slide vertically up and down along the trapezoidal groove to adjust the lateral clamping distance. A vertical screw hole is opened on the top of the adjustable clamping head 2 corresponding to the position of the movable pressure plate 5. A fourth fastening bolt 4 is screwed into the screw hole. Rotating the fourth fastening bolt 4 downward feeds the plate, and the frustum pad at the end of the bolt fits and presses against the top surface of the movable pressure plate 5. The sliding position of the movable pressure plate 5 is locked by friction, thus completing the fixation of the lateral clamping size.

[0034] In this invention, the five bolts—the third fastening bolt 3, the fourth fastening bolt 4, the first fastening bolt 12, the second fastening bolt 10, and the fifth fastening bolt 9—have the same structural specifications: one end of each bolt has a through hole opened laterally, and a cylindrical handle is inserted laterally into the through hole to form a T-shaped operating structure. The operator can directly hold the cylindrical handle to rotate the bolt without the need for a wrench; the other end of the bolt is fixedly fitted with a frustum pad. The frustum pad increases the contact area and evenly distributes the pressure when tightening, avoiding indentations and scratches on the surface of the column and plate. At the same time, the pad can be embedded into the long groove on the outer wall of the supporting column 7 to achieve interlocking and limiting.

[0035] In this embodiment, the bottom thread of the support column 7 is fully screwed into the screw hole on the top surface of the heavy-duty base 11 to complete the assembly of the bottom support unit; the desktop clamping assembly 8 and the adjustable clamping head 2 are sequentially inserted from the top of the column, slid to the appropriate height, and then the second fastening bolt 10 and the first fastening bolt 12 are rotated to lock and fix them; the cable or circuit board to be welded is placed in the inner cavity of the adjustable clamping head 2, the movable upright plate 6 is slid back and forth to the appropriate longitudinal dimension, and the third fastening bolt 3 is rotated to lock; the movable pressure plate 5 is slid up and down to the appropriate lateral dimension, and the fourth fastening bolt 4 is rotated to lock. The workpiece is clamped by the cooperation of the upright plate and the pressure plate, and the operator can carry out welding and maintenance work; after the work is completed, all the fastening bolts are loosened, and the clamping head and the desktop clamping assembly can be pulled out along the column, and the column is unscrewed from the base to complete the complete disassembly and storage.

[0036] Keep the support column 7 and the heavy-duty base 11 threadedly connected. Slide the desktop clamping assembly 8 down to the top of the worktable and rotate the second fastening bolt 10 to lock the assembly height. Rotate the fifth fastening bolt 9 downwards so that the lower end of the bolt presses against the upper surface of the worktable and the bottom surface of the desktop clamping assembly 8 presses against the lower surface of the worktable, thus fixing the whole machine to the worktable. Slide the adjustable clamping head 2 to a comfortable operating height and lock the first fastening bolt 12. Adjust the movable upright plate 6 and the movable pressure plate 5 in the same way as the floor mode to clamp the workpiece and carry out the operation. If no floor counterweight is required, the support column 7 can be completely unscrewed from the heavy-duty base 11, and the whole machine can be fixed by the desktop clamping assembly 8 alone, further simplifying the tooling volume.

[0037] Loosen the first fastening bolt 12 completely, pull out the adjustable clamping head 2 upwards. The clamping head itself forms an independent small clamp by relying on the internal movable upright plate 6 and movable pressure plate 5. It can hold small workpieces by hand to complete offline welding and repair, thus expanding the application scenarios of tooling.

[0038] The four axial grooves on the outer side of the support column 7 form a continuous limiting structure. When the bolts are rotated and tightened at any height, the end truncated block can be embedded in the groove to form a concave-convex interlocking structure, which avoids axial slippage when the smooth cylindrical rod is locked, ensuring the long-term stability of the support height and preventing loosening or displacement even after repeated adjustments.

[0039] The movable upright plate 6 and the movable pressure plate 5 belong to two sets of trapezoidal sliding grooves that do not interfere with each other. Their sliding movements are independent of each other, and the longitudinal depth and lateral clamping width of the workpiece can be controlled separately. They can adapt to a variety of workpieces, such as single thin wires, multiple bundles of parallel cables, and small PCB circuit boards. The trapezoidal grooves and square plug-in protrusions work together to limit the lateral displacement of the plate body. The clamping size adjustment accuracy is high, and there is no twisting or slippage problem after the workpiece is clamped.

[0040] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
