Description

Technical Field

[0001] The utility model relates to the technical field of machining of mechanical parts, and particularly relates to a welding auxiliary device for machining precision mechanical parts. Background Technique

[0002] Precision mechanical parts refer to small parts that play a key role in mechanical equipment, and their manufacturing and machining require high-precision processes and equipment. These parts are usually made of metal materials (such as steel, aluminum, copper, etc.), have complex shapes and structures, and can ensure the efficient, stable and reliable operation of mechanical equipment after precision machining and assembly. Precision mechanical parts are widely used in mechanical equipment in various fields, such as automobiles, aerospace, electronics, medical equipment, optical instruments, etc.

[0003] The application number is CN202420467247.3, which discloses a welding auxiliary device for machining precision mechanical parts, including a moving component, an adjusting component and a clamping component. The adjusting component is installed on the top of the moving component, and the clamping component is installed at one end of the adjusting component. The clamping component includes a fixing plate, a bidirectional lead screw, an adjusting block, a clamping plate, a transmission belt and a third motor. The bidirectional lead screw is rotatably connected inside the fixing plate, the adjusting block is threadedly connected to the outside of the bidirectional lead screw, and the clamping plate is fixedly connected to one end of the adjusting block. For this welding auxiliary device for machining precision mechanical parts, the first motor drives the movable frame to move up and down, and the second motor drives the rotating block to rotate. One end of the rotating block is fixedly connected to the back of the fixing plate. Thus, the adjusting component can drive the clamping component to perform angle adjustment and flipping, reducing the workload of manual operation and improving the working efficiency of welding.

[0004] The following problems exist in the use process of this device: 1. The rotation constraint of the bidirectional lead screw inside the fixing plate is not designed, and the lead screw is prone to radial swing during operation, resulting in inaccurate adjustment; 2. In the transmission system, there is a lack of rigid connection and shock absorption buffer structure between the motor and the movable frame and the rotating block, and the running vibration will be directly transmitted to the clamping component, causing the parts to shift; 3. The connection methods between the components are not described for stability. Under the influence of welding external force and equipment self-vibration, the overall structure is prone to looseness or relative displacement of components, and it is difficult to ensure the stability required for precision machining. Content of the Utility Model

[0005] The purpose of the present invention is a welding auxiliary device for machining precision mechanical parts, which solves the problem of being difficult to maintain stability under the influence of welding external force and equipment self-vibration.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a welding auxiliary device for machining precision mechanical parts, which includes a fixing component and a fixture component. The fixture component is installed on the inner walls of both sides of the fixing component. The fixing component includes a limiting shell. Two slots are opened on the outer walls of both sides of the limiting shell. A limiting groove is opened on the upper surface of the limiting shell close to the right slot. The cavity of the right slot communicates with the cavity of the limiting groove. A threaded adjusting ring is rotatably connected to the inner wall of the limiting groove. An arc-shaped long push block is inserted into the right slot. Thread grooves are opened on the outer walls of all around the arc-shaped long push block. The arc-shaped long push block and the threaded adjusting ring are in a perpendicular cross state. The thread groove is threadedly connected to the inner wall of the threaded adjusting ring.

[0008] The purpose of such a setting is that during the use of the device, the precision mechanical parts to be welded are placed above the bottom plate, in the area between the anti-slip clamp block one and the anti-slip clamp block two, and the position of the parts is roughly adjusted to prepare for the subsequent clamping operation. Rotate the threaded adjusting ring. Since the threaded adjusting ring and the arc-shaped long push block are threadedly connected, according to the principle of screw drive, as the threaded adjusting ring rotates, the arc-shaped long push block will move linearly in the right slot, moving towards the direction close to the parts. At this time, the anti-slip clamp block two also moves synchronously. While the arc-shaped long push block is moving, the long push block is blocked by the parts and the elastic action of the elastic rod, and moves linearly in the left slot in the reverse direction. The rotating block assists the long push block to move smoothly in the slot. The long push block drives the anti-slip clamp block one at the front end to move towards the direction close to the parts. Finally, the anti-slip clamp block one and the anti-slip clamp block two tightly clamp the precision mechanical parts from both left and right sides. Due to the anti-slip characteristics of the surface of the anti-slip clamp block, it can effectively prevent the parts from displacing during the welding process, ensuring that the parts are fixed in position during welding. After the welding is completed, rotate the threaded adjusting ring in the reverse direction. The arc-shaped long push block drives the anti-slip clamp block two to move away from the parts. At the same time, the long push block moves and resets in the direction away from the parts under the elastic restoring force of the elastic rod, driving the anti-slip clamp block one to move synchronously. When the anti-slip clamp block one and the anti-slip clamp block two completely release the clamping of the parts, the operator can take out the welded precision mechanical parts from the device to complete the entire welding auxiliary process. Through the threaded connection between the threaded adjusting ring and the arc-shaped long push block, precise fine-tuning can be achieved. The threaded connection has good self-locking performance, which can effectively prevent the arc-shaped long push block from loosening and shifting due to factors such as vibration and thermal deformation during the welding process, so that the parts are always stably clamped, ensuring the welding quality.

[0009] Further, the front end of the arc-shaped long push block extends to the outside of the front end of the limiting shell, and an anti-slip clamp block two is provided at the front end of the arc-shaped long push block.

[0010] The purpose of such a setting is that during the use of the device, when the arc-shaped long push block moves, the anti-slip clamp block two moves accordingly. By utilizing its anti-slip property, it can better clamp the right side of the component, preventing the component from shifting on this side during welding.

[0011] Further, a long push block is inserted inside the slot on the left side. A bottom plate is provided on the lower surface of the limit shell. A leveling block is provided on the outer wall of the tail end of the bottom plate close to the long push block, and the tail end of the long push block is parallel to the top end of the leveling block.

[0012] The purpose of such a setting is that during the use of the device, the front end of the arc-shaped long push block extends outside the limit shell and is provided with an anti-slip clamp block two. The long push block is inserted into the slot on the left side. The leveling block on the bottom plate keeps the tail end of the long push block stable, and the long push block can move in the slot, preparing to clamp the left side of the component.

[0013] Further, rotating blocks are rotatably connected to the inner walls on the upper and lower sides at the front end of the slot on the left side, and the rotating blocks are inserted through the inner wall on the right side at the front end of the long push block.

[0014] The purpose of such a setting is that during the use of the device, the rotating blocks can assist the long push block to move smoothly in the slot, and at the same time may limit the moving direction of the long push block to a certain extent, making its movement more accurate.

[0015] Further, elastic rods are fixedly connected to the outer walls on both sides of the long push block. One ends of the two elastic rods are respectively arranged at the front and rear ends of the long push block, and the outer ends of the elastic rods are fixedly connected to the inner walls on both sides of the slot on the left side.

[0016] The purpose of such a setting is that during the use of the device, the elastic rods can provide a certain elastic force, play a buffering role during the movement of the long push block, and can assist it to reset when the long push block is released.

[0017] Further, the front end of the long push block extends outside the front end of the limit shell. An anti-slip clamp block one is provided at the front end of the long push block. The anti-slip clamp block one and the anti-slip clamp block two are parallel to the upper side of the bottom plate.

[0018] The purpose of such a setting is that during the use of the device, when the long push block moves, the anti-slip clamp block one moves accordingly, and in cooperation with the anti-slip clamp block two, it clamps the component from both the left and right sides, preventing the component from shifting during welding.

[0019] The utility model has the following beneficial effects:

[0020] (1) Through the settings of the arc-shaped long push block and the threaded adjustment ring, as the threaded adjustment ring rotates, the arc-shaped long push block will move linearly within the right slot, moving towards the direction close to the component. Through the threaded connection between the threaded adjustment ring and the arc-shaped long push block, precise fine-tuning can be achieved. The threaded connection has good self-locking performance, which can effectively prevent the arc-shaped long push block from loosening and shifting due to factors such as vibration and thermal deformation during the welding process, so that the component is always stably clamped, ensuring the welding quality.

[0021] (2) Through the settings of the rotating block and the elastic rod, the leveling block on the bottom plate keeps the tail end of the long push block stable. The long push block can move within the slot to prepare for clamping the left side of the component. The rotating block can assist the long push block to move smoothly within the slot, and at the same time may limit the moving direction of the long push block to a certain extent, making its movement more precise. The elastic rod can provide a certain elastic force, playing a buffering role during the movement of the long push block, and can assist it to reset when the long push block is released.

[0022] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0031] Please refer to Figures 1-4 As shown in the figure, the present utility model is a welding auxiliary device for processing precision mechanical parts, including a fixing component 1 and a fixture component 2. The fixture component 2 is installed on the inner walls on both sides of the fixing component 1. The fixing component 1 includes a limit shell 103. Two slots 105 are opened on the outer walls on both sides of the limit shell 103. A limit groove 106 is opened on the upper surface of the limit shell 103 close to the right slot 105. The cavity of the right slot 105 communicates with the cavity of the limit groove 106. A threaded adjustment ring 207 is rotatably connected to the inner wall of the limit groove 106. An arc-shaped long push block 204 is inserted into the right slot 105. Thread grooves 205 are opened on the outer walls around the arc-shaped long push block 204. The arc-shaped long push block 204 and the threaded adjustment ring 207 are in a perpendicular cross state. The thread grooves 205 are threadedly connected to the inner wall of the threaded adjustment ring 207.

[0032] The purpose of this setting is that during the use of the device, when the threaded adjustment ring 207 is rotated, since the threaded adjustment ring 207 is threadedly connected to the arc-shaped long push block 204, according to the principle of screw drive, as the threaded adjustment ring 207 rotates, the arc-shaped long push block 204 will move linearly in the right slot 105, moving towards the direction close to the component. At this time, the anti-slip clamp block two 206 also moves synchronously. While the arc-shaped long push block 204 is moving, the long push block 201 is blocked by the component and the elastic action of the elastic rod 202, and moves linearly in the left slot 105 in the reverse direction. The rotating block 104 assists the long push block 201 to move smoothly in the slot 105. The long push block 201 drives the anti-slip clamp block one 203 at the front end to move towards the direction close to the component. Finally, the anti-slip clamp block one 203 and the anti-slip clamp block two 206 tightly clamp the precision mechanical component from the left and right sides. When the arc-shaped long push block 204 drives the anti-slip clamp block two 206 to move away from the component, at the same time, the long push block 201 moves and resets in the direction away from the component under the elastic restoring force of the elastic rod 202, driving the anti-slip clamp block one 203 to move synchronously. When the anti-slip clamp block one 203 and the anti-slip clamp block two 206 completely release the clamping of the component, the operator can take out the welded precision mechanical component from the device, completing the entire welding assistance process. Through the threaded connection between the threaded adjustment ring 207 and the arc-shaped long push block 204, precise fine-tuning can be achieved. The threaded connection has good self-locking performance, which can effectively prevent the arc-shaped long push block 204 from loosening and shifting due to factors such as vibration and thermal deformation during the welding process, so that the component is always stably clamped, ensuring the welding quality.

[0033] The front end of the arc-shaped long push block 204 extends to the outside of the front end of the limit shell 103, and the anti-slip clamp block two 206 is provided at the front end of the arc-shaped long push block 204.

[0034] The purpose of this setting is that during the use of the device, when the arc-shaped long push block 204 moves, the anti-slip clamp block two 206 moves accordingly. Using its anti-slip characteristics, it can better clamp the right side of the component and prevent the component from shifting on this side during welding.

[0035] The long push block 201 is inserted into the left slot 105. The bottom plate 101 is provided on the lower surface of the limit shell 103. A leveling block 102 is provided on the outer wall of the bottom plate 101 close to the tail end of the long push block 201. The tail end of the long push block 201 is parallel to the top end of the leveling block 102.

[0036] The purpose of this setting is that during the use of the device, the front end of the arc-shaped long push block 204 extends outside the limit shell 103 and is provided with the anti-slip clamp block two 206. The long push block 201 is inserted into the left slot 105. The leveling block 102 on the bottom plate 101 keeps the tail end of the long push block 201 stable. The long push block 201 can move in the slot 105 to prepare for clamping the left side of the component.

[0037] Rotating blocks 104 are rotatably connected to the upper and lower inner walls at the front end of the left slot 105, and the rotating blocks 104 are inserted through and arranged on the inner wall at the right front end of the long push block 201.

[0038] The purpose of such a setting is that during the use of the device, the rotating blocks 104 can assist the long push block 201 to move smoothly in the slot 105, and at the same time, to a certain extent, restrict the moving direction of the long push block 201 to make its movement more accurate.

[0039] Elastic rods 202 are fixedly connected to the outer walls on both sides of the long push block 201. One ends of the two elastic rods 202 are respectively arranged at the front and rear ends of the long push block 201, and the outer ends of the elastic rods 202 are fixedly connected to the inner walls on both sides of the left slot 105.

[0040] The purpose of such a setting is that during the use of the device, the elastic rods 202 can provide a certain elastic force to play a buffering role during the movement of the long push block 201, and can assist it to reset when the long push block 201 is released.

[0041] The front end of the long push block 201 extends to the outside of the front end of the limit shell 103. An anti-slip clamping block one 203 is arranged at the front end of the long push block 201. The anti-slip clamping block one 203 and the anti-slip clamping block two 206 are parallel to the upper side of the bottom plate 101.

[0042] The purpose of such a setting is that during the use of the device, when the long push block 201 moves, the anti-slip clamping block one 203 moves accordingly, and cooperates with the anti-slip clamping block two 206 to clamp the parts from the left and right sides to prevent the parts from shifting during welding.

[0043] During use, when the device is in operation, place the precision mechanical components to be welded above the base plate 101, in the area between the anti-slip clamp block one 203 and the anti-slip clamp block two 206. Roughly adjust the position of the components to prepare for the subsequent clamping operation. Rotate the threaded adjustment ring 207. Since the threaded adjustment ring 207 is threadedly connected to the arc-shaped long push block 204, according to the principle of threaded transmission, as the threaded adjustment ring 207 rotates, the arc-shaped long push block 204 will move linearly in the right slot 105, moving towards the direction close to the components. At this time, the anti-slip clamp block two 206 also moves synchronously. While the arc-shaped long push block 204 is moving, the long push block 201 is blocked by the components and the elastic action of the elastic rod 202, and moves linearly in the left slot 105 in the reverse direction. The rotating block 104 assists the long push block 201 to move smoothly in the slot 105. The long push block 201 drives the anti-slip clamp block one 203 at the front end to move towards the direction close to the components. Finally, the anti-slip clamp block one 203 and the anti-slip clamp block two 206 tightly clamp the precision mechanical components from both left and right sides. Due to the anti-slip characteristics of the surface of the anti-slip clamp blocks, it can effectively prevent the components from shifting during the welding process, ensuring that the components are fixed in position during welding. After welding is completed, rotate the threaded adjustment ring 207 in the reverse direction. The arc-shaped long push block 204 drives the anti-slip clamp block two 206 to move away from the components. At the same time, the long push block 201 moves in the reverse direction and resets under the elastic restoring force of the elastic rod 202, driving the anti-slip clamp block one 203 to move synchronously. When the anti-slip clamp block one 203 and the anti-slip clamp block two 206 completely release the clamping of the components, the operator can take out the welded precision mechanical components from the device, completing the entire welding assistance process. Through the threaded connection between the threaded adjustment ring 207 and the arc-shaped long push block 204, precise fine-tuning can be achieved. The threaded connection has good self-locking performance, which can effectively prevent the arc-shaped long push block 204 from loosening and shifting due to factors such as vibration and thermal deformation during the welding process, so that the components are always stably clamped, ensuring the welding quality.
