Description

Technical Field

[0001] The invention relates to the technical field of sheet metal welding, in particular to a sheet metal welding device with a positioning function. Background Art

[0002] Sheet metal welding is a process of welding multiple sheet metal parts together to achieve the purpose of processing and to increase their strength. It is an important part of my country's manufacturing industry. In the process of sheet metal welding, in order to ensure the welding quality between two sheet metal parts, the welding positions of the sheet metal parts need to be docked and positioned to ensure that the distance between the welding surfaces of the two sheet metal parts is equal, providing a basic guarantee for later welding. However, the position adjustment between the two existing sheet metal parts is mainly carried out by manual positioning, and the accuracy is low. When the distance between the welding surfaces of the two sheet metal parts is inconsistent (that is, when the sheet metal parts are tilted), the welding quality will be affected. When installing and positioning two large sheet metal parts, due to the limited distance between the operating table and the welding mechanism, the loading of the sheet metal parts will be hindered, and the excitation adjustment between the large sheet metal parts will be more inconvenient. Therefore, in view of the above problems, a sheet metal welding device with a positioning function is designed to better meet the actual use needs. Summary of the invention

[0005] Preferably, four legs are vertically fixed to the lower end surface of the panel, and a limit plate is fixed to the front side of the upper end surface of the panel, and the limit plate is symmetrically provided with guide rail sides, and the guide rails are symmetrically fixed to the upper end surface of the panel. Through the above structure, a basic guarantee can be provided for the normal operation of the device.

[0006] Preferably, a slider is fixed symmetrically on the lower end surface of the operating table, and the slider is slidably connected to the guide rail, and a protrusion is fixed on the slider, and the contact between the protrusion and the limit plate can realize the positioning effect. When the operating table is subjected to force to move, the stability of the movement of the operating table can be ensured by the sliding guiding effect between the slider and the guide rail, and the maximum distance of the movement of the operating table can be limited by the contact between the protrusion and the limit plate, thereby avoiding the separation of the slider and the guide rail, thereby ensuring the normal operation of the device.

[0007] Preferably, the front end surface of the operating table is also rotatably connected to one end of a support rod, and the other end of the support rod is rotatably connected to a movable block, and the movable block is slidably connected to the support foot, and the support rods are symmetrically distributed about the center line of the operating table. When the operating table moves forward, the rotation of the support rod and the action of the movable block can support the operating table, thereby ensuring the stability of the operating table.

[0008] Preferably, one end of the second spring is fixed to the lower end of the convex strip, and the other end of the second spring is fixed to the operating table, and a guide rod is also fixed to the lower end surface of the convex strip, and the guide rod and the operating table are slidably connected, and the width of the convex strip is 1-3mm.

[0009] Preferably, a cross bar fixed on the operating table is provided directly above the first threaded rod, and the cross bar and the connecting plate are slidably connected. When the splint moves, the sliding guiding effect between the cross bar and the connecting plate can ensure that the splint performs stable linear motion.

[0010] Preferably, a baffle is also fixed on the clamping plate, and the width of the baffle is greater than half the width of the U-shaped frame.

When welding, the sheet metal part can be limited up and down by the U-shaped frame and the ball bearing to ensure normal welding. In addition, the rolling action of the ball bearing can reduce the friction between the U-shaped frame and the sheet metal part, providing basic guarantee for the normal movement of the U-shaped frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the sheet metal welding device with positioning function adopts an expandable operating table structure, which can be conveniently moved outward to avoid the welding mechanism from blocking the installation and fixation of the sheet metal parts, and when the operating table is reset, the position of the clamping plate can be adjusted through the transmission effect between the convex tooth plate and the gear, and the sheet metal parts can be driven to move through the clamping plate until the sheet metal parts contact the convex strips, thereby realizing the automatic positioning of the sheet metal parts, and ensuring that the distance between the welding surfaces of the two sheet metal parts is equal, thereby ensuring the welding quality of the sheet metal parts in the later stage. The specific contents are as follows: 1. When loading large-sized sheet metal parts, the sheet metal welding device with positioning function can drive the operating table to move outward by extending the first cylinder, thereby facilitating the placement of large-sized sheet metal parts, avoiding the installation of sheet metal parts affected by the obstruction of the welding mechanism, and improving the convenience of operation. When the operating table moves outward, the supporting rod and the convex block can support the suspended side of the operating table to ensure the stability of the operating table. 2. The sheet metal welding device with a positioning function, when the operating table drives the sheet metal to reset, the position of the clamping plate can be adjusted through the transmission effect between the gear and the convex tooth plate, in cooperation with the threaded connection between the first threaded rod and the connecting plate, thereby driving the sheet metal to move until the welding surface of the sheet metal contacts the convex strip, and when the operating table is not completely reset at this time, the gear and the convex tooth plate can slide through the action of the first spring, thereby providing a basic guarantee for the normal operation of the device, and the two sheet metal welding surfaces are in contact with the convex strip, which can ensure that the distance between the two sheet metal welding surfaces is consistent, providing a basic guarantee for the welding quality of the sheet metal; 3. When welding sheet metal parts, the sheet metal welding device with positioning function can realize the compression and positioning of the sheet metal parts through the action of the U-shaped frame and the ball bearing, thereby ensuring the stability of the sheet metal parts during the welding process, and in combination with the action of the pressure rod and the action of the second spring, the convex strip can be retracted into the operating table, thereby effectively preventing the convex strip from affecting the normal welding of the sheet metal parts.

[0019] Four legs 101 are vertically fixed to the lower end surface of the panel 1, and a limit plate 102 is fixed to the front side of the upper end surface of the panel 1, and the limit plate 102 is symmetrically provided with the side of the guide rail 103, and the guide rail 103 is symmetrically fixed to the upper end surface of the panel 1; a slider 501 is also symmetrically fixed to the lower end surface of the operating table 5, and the slider 501 is slidably connected to the guide rail 103, and a protrusion 502 is also fixed on the slider 501, and the protrusion 502 contacts the limit plate 102 to achieve positioning; the operating table 5 The front end surface is also rotatably connected to one end of a support rod 503, and the other end of the support rod 503 is rotatably connected to a movable block 504, and the movable block 504 is slidably connected to the support leg 101, and the support rod 503 is symmetrically distributed about the center line of the operating table 5; a cross bar 702 fixed to the operating table 5 is arranged directly above the first threaded rod 7, and the cross bar 702 is slidably connected to the connecting plate 801; a baffle 802 is also fixed to the clamping plate 8, and the width of the baffle 802 is greater than half the width of the U-shaped frame 11; When using the sheet metal welding device with positioning function, Figure 1-Figure 7As shown, when placing the sheet metal parts, the operating platform 5 is driven to move forward by controlling the extension of the first cylinder 4, and the sliding guide effect between the slider 501 and the guide rail 103 can ensure the stability of the movement of the operating platform 5. When the operating platform 5 moves forward, the front support rod 503 of the operating platform 5 is rotated by force. Through the transmission effect of the support rod 503, the movable block 504 can slide upward on the support leg 101 until the protrusion 502 contacts the limit plate 102, and the forward movement of the operating platform 5 is completed. At this time, with the support effect of the support rod 503, the operating platform 5 can be suspended in the air. The front side of the operating platform 5 is supported to ensure the stability of the operating platform 5. When the operating platform 5 moves forward, the first threaded rod 7 and the gear 701 are driven forward at the same time. The meshing transmission action between the gear 701 and the convex tooth plate 303 can make the first threaded rod 7 rotate under force. The threaded connection action between the first threaded rod 7 and the connecting plate 801 and the sliding guide action between the connecting plate 801 and the cross bar 702 can make the two clamping plates 8 move in opposite directions, thereby increasing the distance between the two clamping plates 8. When the forward movement of the operating platform 5 is completed, the distance between the two clamping plates 8 is at the maximum position. Figure 2 As shown, the two sheet metal parts to be welded are placed on the operating table 5, and the side of the sheet metal part close to the clamping plate 8 is in contact with the clamping plate 8, and the rear side of the sheet metal part is in contact with the baffle 802. After the sheet metal parts are placed, the operating table 5 can be driven to move backward and reset by controlling the contraction of the first cylinder 4. During the backward movement of the operating table 5, when the gear 701 is engaged with the convex tooth plate 303, according to the above principle, the two clamping plates 8 can be moved toward each other, thereby reducing the distance between the two clamping plates 8. When the clamping plates 8 move toward each other, the two sheet metal parts can be synchronously driven to move toward each other, thereby reducing the distance between the two sheet metal parts, until the side of the two sheet metal parts close to the convex strip 6 is in contact with the convex strip 6 to realize the positioning of the sheet metal parts. At this time, the operating table 5 continues to move backward and reset. Since the position of the clamping plate 8 is fixed at this time, the first When the gear 701 is moved backward with the operating platform 5, the gear 701 exerts a force on the convex tooth plate 303, so that the convex tooth plate 303 and the movable plate 3 are forced to move downward, and the sliding guide effect between the slide bar 301 and the panel 1 can ensure the stability of the movement of the convex tooth plate 303 and the movable plate 3, so that the gear 701 can be separated from the convex tooth plate 303 to ensure the normal backward movement of the gear 701. When the operating platform 5 is reset, the convex tooth plate 303 can be reset to mesh with the gear 701 through the elastic effect of the first spring 302 to ensure the normal operation of the device. At this time, the welding surfaces of the two sheet metal parts close to the convex strip 6 are in contact with the convex strip 6, which can ensure that the distance between the welding surfaces of the two sheet metal parts is equal, thereby ensuring the subsequent welding quality of the sheet metal parts. One end of the second spring 601 is fixed to the lower end of the convex strip 6, and the other end of the second spring 601 is fixed to the operating table 5. A guide rod 602 is also fixed to the lower end surface of the convex strip 6, and the guide rod 602 is slidably connected to the operating table 5, and the width of the convex strip 6 is 1-3mm; a motor 901 is fixed to the front end surface of the mounting frame 9, and a second threaded rod 902 is fixed to the output end of the motor 901, and the second threaded rod 902 is bearing-connected to the mounting frame 9, and a fixing rod 903 directly above the second threaded rod 902 is also fixed to the mounting frame 9; a connecting block 1001 is also fixed to the upper end surface of the second cylinder 10, and the connecting block 1001 is threadedly connected to the second threaded rod 902, and the connecting block 1001 is slidably connected to the fixing rod 903; a ball 1101 is also installed on the lower end surface of the U-shaped frame 11, and the ball 1101 contacts the sheet metal and can roll; When the operation panel 5 is reset, Figure 1-Figure 7 As shown, at this time, the welding gap between the two sheet metal parts is located directly below the welding head 1102. By controlling the start-up of the second cylinder 10, the U-shaped frame 11 and the welding head 1102 can be driven to move downward. When the pressure rod 1103 contacts the convex strip 6, the convex strip 6 is forced to slide downward, and the sliding guide effect between the guide rod 602 and the operating table 5 can ensure the stability of the movement of the convex strip 6. At this time, the second spring 601 is forced to shrink until the ball 1101 on the lower end surface of the U-shaped frame 11 contacts the sheet metal part, which can realize the clamping and limiting effect of the sheet metal part, and at this time, the convex strip 6 is completely moved down into the operating table 5 to prevent the convex strip 6 from affecting the subsequent welding of the sheet metal part, and at this time, the welding head 1102 is located at the welding gap of the sheet metal part. The U-shaped frame 11 and the welding head 1102 are moved by the threaded connection between the second threaded rod 902 and the connecting block 1001 and the sliding action between the connecting block 1001 and the fixed rod 903. The rolling action between the ball 1101 and the sheet metal can reduce the friction between the U-shaped frame 11 and the sheet metal, thereby ensuring the normal movement of the U-shaped frame 11. The sheet metal can be welded by moving the welding head 1102, and since the distance between the welding gaps of the sheet metal parts is the same, the welding quality of the sheet metal parts can be effectively guaranteed. This is the working principle of the sheet metal welding device with positioning function.
