Welding fixture for touch display housing of special computer

Abstract

This invention relates to the field of touch display casing welding technology, specifically to a welding fixture for a special computer touch display casing. It primarily addresses the problem of easy deformation of the casing frame and proposes the following technical solution: a support table, a casing frame on the support table, and a welding pen mounted on the support table. It also includes an outer clamping assembly mounted on the support table to clamp the outer walls of the casing frame and an inner support assembly mounted on the support table to abut against the inner walls of the casing frame. By incorporating the inner support assembly, this invention achieves the effect of simultaneously clamping the casing frame from the outside via the outer clamping assembly and abutting against the inner walls of the casing frame. This allows the casing frame to be subjected to forces from both the external sides and the inner walls, thus counteracting the external forces from the inside out, preventing twisting deformation of the casing frame. Furthermore, because the inner walls of the casing frame are abutted, it is less likely to fall off if the clamping force is insufficient.

Description

Technical Field

[0001] This invention relates to the field of touch display housing welding technology, and more specifically to a welding fixture for a special computer touch display housing. Background Technology

[0002] Special-purpose computers are industrial computers with special functions, designed specifically for harsh industrial environments. They feature reinforced casings and dustproof and waterproof designs. The touchscreen displays of special-purpose computers are touch-enabled displays, allowing users to operate the host computer simply by lightly touching the icons or text on the screen. Welding fixtures are used to ensure the size of welded parts, improve assembly accuracy and efficiency, and prevent welding deformation. The casings of touchscreen displays used in special-purpose computers are typically made of materials such as aluminum alloy and steel. Welding fixtures are used to fix these rigid frames, ensuring structural strength and assembly accuracy. Welding fixtures can adapt to casings of different sizes, ensuring the stability of the frame structure during welding. This type of design is for metal frames that need to withstand mechanical stress or be assembled.

[0003] In existing technologies, the main difficulties in welding and clamping touch display housings are concentrated at the housing frame. When welding the touch display housing frame, traditional welding fixtures only clamp and fix it from the outside of the housing frame. When the housing frame is subjected to excessive external force during clamping, it is prone to deformation. When the clamping force is insufficient, it is easy to fall off. Moreover, the fixed welding angle can easily affect the welding accuracy. To address these issues, we propose a special welding fixture for computer touch display housings. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of the present invention is to provide a welding fixture for a special computer touch display housing, which solves the problem that the housing frame is prone to deformation in the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding fixture for a special computer touch display housing, comprising: a support table, a housing frame on the support table, and a welding pen disposed on the support table; further comprising an outer clamping assembly disposed on the support table for clamping the outer sides of the outer wall of the housing frame, and an inner support assembly disposed on the support table for abutting the inner sides of the inner wall of the housing frame; the outer clamping assembly comprises two L-shaped rods fixedly connected to the top sides of the support table, a first limiting rod fixedly connected between the opposing surfaces of the two L-shaped rods, a left-hand and right-hand screw rod rotatably disposed between the opposing surfaces of the two L-shaped rods, two first clamping plates symmetrically slidably sleeved on the surface of the first limiting rod, and a second clamping plate rotatably disposed on the upper part of the two first clamping plates for clamping one side of the outer wall of the housing frame; the two first clamping plates are respectively engaged with the surfaces of the left-hand and right-hand screw rods.

[0006] Furthermore, the inner support assembly includes a first round rod fixedly connected to the top of the support table, a second transmission rod rotatably mounted on the first round rod, a first transmission rod and a third transmission rod mounted above the second transmission rod, a third support rod fixedly connected to the surface of the first transmission rod, a fourth support rod fixedly connected to the surface of the third transmission rod, a third limiting rod and a second limiting rod fixedly connected to the opposite surfaces of the two L-shaped rods, two first support rods symmetrically slidably mounted on the second limiting rod and the third limiting rod, two first springs slidably mounted on the second limiting rod, a T-shaped limiting rod fixedly connected to the top of the support table, and a second support rod rotatably mounted at one end of the two first support rods to abut against one side of the inner wall of the outer frame of the machine casing.

[0007] Furthermore, one end of the first transmission rod is fixedly connected to the surface of the first clamping plate, and the first transmission rod and the third transmission rod slide through the interior of the T-shaped limiting rod and slide in cooperation with its inner wall.

[0008] Furthermore, the fourth and third support rods are symmetrically slidably sleeved on the surface of the second limiting rod, the two first springs are respectively located between the opposite surfaces of the first and third support rods and engaged, and the side wall of the other first support rod is engaged with the opposite surface of the fourth support rod.

[0009] Furthermore, the surface of the second transmission rod has two symmetrically distributed strip holes, and the inner walls of both sets of strip holes are slidably fitted with first limiting round rods, which are fixedly connected to the lower ends of the first transmission rod and the third transmission rod, respectively.

[0010] Furthermore, the two first support rods are provided with angle adjustment components for controlling the angle of the outer frame of the housing. The angle adjustment components include two sets of limiting cylinders respectively fixedly connected to one side of the top of the first support rod, an intermediate rod slidably inserted into the two limiting cylinders, two sets of limiting seats fixedly connected to the surfaces of the two sets of limiting cylinders, a first square rod penetrating the surface of the limiting seat, a slide fixedly connected to the end of the first square rod, a second square rod fixedly connected to the end of the slide, a second spring slidably sleeved on the second square rod, a first linkage rod rotatably set on the top of the limiting seat, a first guide rod fixedly inserted into the first linkage rod, an irregularly shaped guide groove opened on the top of the slide, a second pressing plate hinged to one end of one of the first square rods by a hinge, and a first pressing plate hinged to one end of the other first square rod by a hinge.

[0011] Furthermore, the first pressing plate is movably inserted into the second pressing plate, the slide slides in the limiting seat, the second square rod passes through the limiting seat, the second spring is located between the opposite surfaces of the slide and the limiting seat and is engaged, and the first guide rod is inserted into the irregular guide groove and slides in cooperation with its inner wall.

[0012] Furthermore, a seventh limiting groove is provided in both of the limiting cylinders, and a seventh limiting block is provided on both sides of the top and bottom of the intermediate rod. The seventh limiting block is slidably inserted into the seventh limiting groove, and the bottom of the inner wall of the irregular guide groove is a limiting irregular slope.

[0014] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0015] 1. By setting the inner support component, the outer clamping component can clamp the outer frame of the housing from the outside while simultaneously abutting against the inner walls of the housing frame. This allows the housing frame to be subjected to forces from both the outside and the inner walls, thus offsetting the forces from the outside from the inside out. This prevents the housing frame from twisting and deforming. Furthermore, because the inner walls of the housing frame are abutted, it is less likely to fall off when the clamping force is insufficient.

[0016] Second, by setting up an angle adjustment component, the angle of the clamped outer frame of the housing can be changed by pressing the pressing rod on the welding pen during welding. This allows the outer frame of the housing to be welded from different angles, improving the welding accuracy of the outer frame of the housing. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention will be further described in detail below with reference to the embodiments.

[0033] Example 1, refer to Appendix Figure 1-12As shown, in this embodiment, in order to solve the problem of easy deformation of the housing frame in the prior art, the present invention discloses a welding fixture for a special computer touch display housing, including: a handle fixedly connected to one end of a left-right rotating lead screw 73; a first through hole opened at the contact point between the limiting cylinder 991 and the limiting seat 91; a second square rod 96 movably inserted into the first through hole; the thickness of the limiting cylinder 991 is the same as the displacement length of the first square rod 921 and the second square rod 96; the first through hole prevents the second square rod 96 from being blocked, allowing the second square rod 96 to move and extend; the bottom of the limiting seat 91 has a sleeve, which is fitted onto the second square rod 96. The outer side, and the length of the sleeve is equal to the displacement length of the second square rod 96, support table 1, outer frame 3 of the housing on support table 1 and welding pen 2 set on support table 1, welding pen 2 is used to weld outer frame 3 of housing, support table 1 is used for support, and also includes outer clamping assembly 7 set on support table 1 for clamping the outer side wall of outer frame 3 on both sides, outer clamping assembly 7 is used to clamp the outer side wall of outer frame 3 on both sides and inner support assembly 8 set on support table 1 for abutting the inner side wall of outer frame 3 on both sides, inner support assembly 8 is used to abut the inner side wall of outer frame 3 on both sides, offset the clamping force of the second clamping plate 77 part, and prevent outer frame 3 of housing from being clamped. The heat generated during welding makes the plates susceptible to deformation due to the forces of the clamping forces on both sides. The outer clamping assembly 7 includes two L-shaped rods 71 ​​and a first limiting rod 72 fixedly connected to the top sides of the support table 1. The L-shaped rods 71 ​​support the first limiting rod 72, the left and right rotating screws 73, the second limiting rod 78, and the third limiting rod 79. The first limiting rod 72 limits the position of the first clamping plate 75. The left and right rotating screws 73, which are rotated between the opposite faces of the two L-shaped rods 71, drive the first clamping plate 75, causing the two first clamping plates 75 to move closer or further apart, and symmetrically slide on the surface of the first limiting rod 72. The two first clamping plates 75 are used to drive the two second clamping plates 77 to move closer or further apart, thus clamping the outer wall of the outer frame 3 of the housing. The second clamping plates 77, which are rotatably set on the upper part of the two first clamping plates 75, are used to clamp one side of the outer wall of the outer frame 3 of the housing. The two first clamping plates 75 are respectively meshed with the surfaces of the left and right screw rods 73. Through the cooperation of the threaded holes on the first clamping plates 75 and the threaded sleeves on the left and right screw rods 73, the rotation of the left and right screw rods 73 can drive the first clamping plates 75 to move. The first clamping plates 75 move left and right on the first limiting rod 72.The inner support assembly 8 includes a first round rod 81 fixedly connected to the top of the support table 1, which provides support. A second transmission rod 82 is rotatably mounted on the first round rod 81, allowing the first transmission rod 84 to drive the second transmission rod 82 to rotate. A third transmission rod 85 is positioned above the second transmission rod 82, which in turn drives the second transmission rod 82 to rotate, simultaneously moving the third transmission rod 85. The third transmission rod 85 and the second transmission rod 82... The movement of the first transmission rod 84 is simultaneous with the movement of the second transmission rod 82. The second transmission rod 82 drives the third transmission rod 85 to move in the opposite direction to the first transmission rod 84. The third support rod 86, fixedly connected to the surface of the first transmission rod 84, is used to push the first spring 792 to drive the first support rod 791 to abut against the outer frame 3 of the housing. The fourth support rod 87, fixedly connected to the surface of the third transmission rod 85, is used to push the first spring 792 to drive the first support rod 791 to abut against the outer frame of the housing. On the other inner wall of 3, a third limiting rod 79 is fixedly connected to the opposite faces of the two L-shaped rods 71. The third limiting rod 79 limits the first support rod 791. A second limiting rod 78 is fixedly connected between the upper side walls of the two L-shaped rods 71. The second limiting rod 78 limits the first support rod 791. Two first support rods 791 are symmetrically slidably sleeved on the second limiting rod 78 and the third limiting rod 79, respectively. The first support rods 791 are used to transmit the compressive force exerted by the first spring 792 on the first support rod 791. The two first springs 792 on the second limiting rod 78 are used to flexibly transmit the force from the third support rod 86 and the fourth support rod 87 to the first support rod 791. The T-shaped limiting rod 83 is fixedly connected to the top of the support table 1. The T-shaped limiting rod 83 is used to limit the first transmission rod 84 and the third transmission rod 85. The two second support rods 793 are respectively rotatably set at one end of the two first support rods 791 to abut against one side of the inner wall of the outer frame 3. The two second support rods 793 are used to support the inner wall of the outer frame 3 and counteract the pressure from the outer wall of the outer frame 3.One end of the first transmission rod 84 is fixedly connected to the surface of the first clamping plate 75 to transmit force. This causes the first clamping plate 75 to drive the second clamping plate 77 to clamp the outer frame 3 of the housing, while simultaneously driving the second support rod 793 to abut against the inner wall of the outer frame 3. The first transmission rod 84 and the third transmission rod 85 slide through the interior of the T-shaped limiting rod 83 and slide against its inner wall, thus limiting the first transmission rod 84 and the third transmission rod 85. The fourth support rod 87 and the third support rod 86 are symmetrically slidably sleeved on the surface of the second limiting rod 78, which is used to limit the fourth support rod 87 and the third support rod 893. The strut 86 is limited, and two first springs 792 are respectively positioned and engaged between the opposing surfaces of the first strut 791 and the third strut 86, and the side wall of another first strut 791 is engaged between the opposing surface of the fourth strut 87. The first springs 792 flexibly transmit force, allowing the first strut 791 to slide left and right on the second limiting rod 78 and the third limiting rod 79. The first strut 791 slides left and right on the circumferential sides of the second limiting rod 78 and the third limiting rod 79. The first spring 792 slides left and right on the second limiting rod 78 and on the circumferential side of the second limiting rod 78.

[0034] Both L-shaped rods 71 ​​are fixedly inserted with first bearings, and left and right spiral screws 73 pass through the first bearings respectively. The first bearings facilitate the rotation of the left and right spiral screws 73 and prevent the left and right spiral screws 73 from moving. The outer side wall of the left and right spiral screws 73 is fixedly connected to the inner ring side wall of the first bearing.

[0035] Two first clamping plates 75 are respectively rotatably inserted with second bearings. The rotatable design makes it easy to adjust the clamping angle. The second clamping plates 77 can rotate through the second bearings. The ends of the two second bearings are respectively fixedly connected to one side of the second clamping plate 77.

[0036] A third bearing is fixedly inserted in the second transmission rod 82. The third bearing facilitates the rotation of the second transmission rod 82 and prevents the second transmission rod 82 from moving. The first round rod 81 passes through the third bearing, and the outer side wall of the third bearing is fixedly connected to the inner ring side wall of the third bearing.

[0037] Two symmetrically distributed strip holes 89 penetrate the surface of the second transmission rod 82. The strip holes 89 allow the third transmission rod 85 and the first transmission rod 84 to move through the second transmission rod 82 without getting stuck. The inner walls of both sets of strip holes 89 are slidably fitted with first limiting round rods 891. Through the cooperation of the first limiting round rods 891 and the strip holes 89, the force on the first transmission rod 84 can be transmitted to the third transmission rod 85 through the second transmission rod 82, causing the first transmission rod 84 and the third transmission rod 85 to move in opposite directions. The first limiting round rods 891 are fixedly connected to the lower ends of the first transmission rod 84 and the third transmission rod 85, respectively.

[0038] Two first support rods 791 are rotatably inserted into one end of each first support rod 791. The first pins facilitate the rotation of the second support rod 793 on the first support rod 791 and prevent the second support rod 793 from moving. The ends of the two first pins are fixedly connected to one side of the second support rod 793.

[0039] Angle adjustment components 9 are provided on the two first support rods 791 to control the angle of the outer frame 3 of the housing. The angle adjustment components 9 adjust the angle of the outer frame 3 of the housing. The angle adjustment components 9 include two sets of limiting cylinders 991 respectively fixedly connected to one side of the top of the first support rod 791. The structure on the angle adjustment components 9 has the same effect as a ballpoint pen: pressing to extend the pen tip and pressing again to retract the pen tip. Through the cooperation of the limiting cylinders 991 and the intermediate rod 992, the movement of the first pressing plate 993 and the second pressing plate 994 is more stable when they move closer and further apart, increasing positioning accuracy. Precision is achieved by inserting an intermediate rod 992 into two limiting cylinders 991. The intermediate rod 992 is used to insert into the limiting cylinders 991 and is fixedly connected to two sets of limiting seats 91 on the surfaces of the two sets of limiting cylinders 991. The limiting cylinders 991 drive the limiting seats 91 to move. A first square rod 921 passes through the surface of the limiting seat 91 and moves within the limiting seat 91, while simultaneously limiting the slide block 92. The slide block 92 is fixedly connected to the end of the first square rod 921. The slide block 92 can push the second square rod 96 to move. The slide block 96 is fixedly connected to the end of the slide block 92. The second square rod 96 limits the movement of the second spring 97 and the slide block 92. The second spring 97, which is slidably sleeved on the second square rod 96, causes the first guide rod 98 to be locked in the upper or lower part of the irregular guide groove 93 by the force of the second spring 97, forming a locked state. The first linkage rod 94, which is set on the top of the limiting seat 91, rotates and moves the slide block 92. The shape of the irregular guide groove 93 causes the first guide rod 98 to be locked in the upper or lower part of the irregular guide groove 93, and is fixedly inserted into the first... The first guide rod 98 inside the linkage rod 94 is inserted into the irregular guide groove 93 on the top of the slide block 92. The irregular guide groove 93 limits the first guide rod 98. The second pressing plate 994 is hinged to one end of one of the first square rods 921 by a hinge 1, and the first pressing plate 993 is hinged to one end of the other first square rod 921 by a hinge 2. The hinged manner allows the second pressing plate 994 and the first pressing plate 993 to rotate up and down, which facilitates the adjustment of the welding angle of the outer frame 3 of the housing.

[0040] The second pressing plate 994 and the first pressing plate 993 are flipped up and down. One side of the second pressing plate 994 and the other side of the outer frame 3 of the first pressing plate 993 are convenient for pressing against the outer frame 3 of the housing.

[0041] The first pressing plate 993 is movably inserted into the second pressing plate 994, which facilitates the first pressing plate 993 and the second pressing plate 994 to move closer or further apart. The slide 92 slides in the limiting seat 91, which has a limiting effect. The second square rod 96 passes through the limiting seat 91, which limits the second square rod 96. The second spring 97 is located between the slide 92 and the inner wall of the limiting seat 91 and is engaged. The first guide rod 98 is inserted into the irregular guide groove 93 and slides with its inner wall. The bottom of the first guide rod 98 is in contact with the bottom of the inner wall of the irregular guide groove 93 and is used to press against the limiting irregular slope 99.

[0042] The first linkage rod 94 is rotatably connected to the limiting seat 91 via the second pin. The second pin allows the first linkage rod 94 to rotate while preventing it from moving. The bottom of the second pin is fixedly connected to the top side of the limiting seat 91 for a fixing effect. Each of the two limiting cylinders 991 has a seventh limiting groove 997. The middle rod 992 has seventh limiting blocks 998 on both sides of its top and bottom. The seventh limiting blocks 998 slide into the seventh limiting grooves 997. The cooperation between the seventh limiting grooves 997 and the seventh limiting blocks 998 achieves the function of limiting... The positioning effect increases the accuracy of the movement of the limiting cylinder 991. The bottom of the inner wall of the irregular guide groove 93 is a limiting irregular slope 99. When the first square rod 921 is pressed, the first guide rod 98 can only be at the bottom or top of the irregular guide groove 93. Through the contact between the top of the limiting irregular slope 99 and the bottom of the first guide rod 98, when the first guide rod 98 is at the top or bottom of the irregular guide groove 93, pressing the first square rod 921 again allows the first guide rod 98 to move from high to low along the slope of the top or bottom of the limiting irregular slope 99, thereby achieving the effect of repositioning.

[0043] The second pressing plate 994 has strip-shaped guide grooves on both sides. Through the cooperation of the strip-shaped guide grooves and the eighth limiting block, the movement of the second pressing plate 994 and the first pressing plate 993 can be limited to increase accuracy. The first pressing plate 993 has an eighth limiting block on each of its two ends, which is movably inserted into the strip-shaped guide groove. The overall structure is similar to a ballpoint pen press-type structure; pressing once releases the pressure, and pressing again resets it. One end of the welding pen 2 is fixedly connected to a pressing rod 999 for supporting the first pressing plate 993 and the second pressing plate 994. The limiting irregular slope 99 can support the pressure rod. Press the first pressing plate 993 or the second pressing plate 994 to press the first square rod 921, so that the second pressing plate 994 and the first pressing plate 993 are away from or close to the outer frame 3 of the housing. When the second pressing plate 994 and the first pressing plate 993 are close to and in contact with the outer frame 3 of the housing, the second support rod 793 and the second clamping plate 77, the outer frame 3 of the housing can be vertically fixed. When the second pressing plate 994 and the first pressing plate 993 are away from the outer frame 3 of the housing, the second support rod 793 and the second clamping plate 77, the outer frame 3 of the housing can be pushed to change the angle of the outer frame 3 of the housing and find a better welding angle.

[0044] Working principle:

[0045] S1. Press the second pressing plate 994 or the first pressing plate 993 using the pressing rod 999 on the welding pen 2, causing the first pressing plate 993 and the second pressing plate 994 to move away from the second support rod 793. Place the outer frame 3 of the housing outside the two second support rods 793. Through the force of the first spring 792, the two second support rods 793 abut against the inner wall of the outer frame 3 of the housing. Turn the handle to drive the left and right screw rods 73 to rotate, so that the second clamping plate 77 clamps the outer frame 3 of the housing, while increasing the force of the second support rods 793 against the outer frame 3 of the housing until the outer frame 3 of the housing is fixed.

[0046] S2. When the outer frame 3 of the housing is fixed in a vertical state, by pressing the pressing rod 999, the first pressing plate 993 and the second pressing plate 994 abut against the outer frame 3 of the housing, thereby fixing the vertical state of the outer frame 3 of the housing. Then, the outer frame 3 of the housing can be welded using the welding pen 2.

[0047] S3. When it is inconvenient to weld the vertical outer frame 3 of the housing, press the pressing rod 999 again to make the first pressing plate 993 and the second pressing plate 994 move away from the outer frame 3 of the housing, so that the outer frame 3 of the housing can drive the second clamping plate 77 and the second support rod 793 to rotate, adjust the angle of the outer frame 3 of the housing, and better weld the outer frame 3 of the housing.
