Description

Technical Field

[0001] The utility model relates to the technical field of welding processing, in particular to a correction and compensation device. Background Art

[0002] In the production process of automobiles and other equipment, a large number of metal parts are usually required. In order to meet the use requirements of these parts, the parts usually need to be welded. During the welding process, the metal parts need to be heated to change the internal structure of the metal, thereby generating stress and strain. The uneven temperature distribution of the welding process and the local plastic deformation and different specific volume structures caused by it make the parts easy to deform after welding. The deformation of the parts after welding can easily affect the appearance and precision of the parts and reduce the quality of the parts processing. Therefore, the parts usually need to be corrected after welding.

[0003] For example, the patent document with publication number CN 109482675 A discloses a bending deformation correction device for butt welding of stainless steel thin-walled steel pipes, comprising a welding gun fixing ring surrounding the outer periphery of the weld of the butt welding of the stainless steel thin-walled steel pipe for fixing the argon arc welding gun, a fixed seat ring and a movable seat ring arranged at both ends of the welding gun fixing ring and respectively sleeved on the outer circle of the stainless steel thin-walled steel pipe, the welding gun fixing ring is rotatably arranged on the fixed seat ring, the front end of the argon arc welding gun enters the inner hole of the welding gun fixing ring and is aligned with the weld, and a clamping device for clamping the welding gun fixing ring between the fixed seat ring and the movable seat ring is connected between the fixed seat ring and the movable seat ring.

[0004] Although the above technical solution can correct the welding bending deformation of stainless steel thin-walled steel pipes, after the welding bending deformation correction process of stainless steel thin-walled steel pipes and other parts, due to errors during correction or the increase in local temperature of the parts during the correction process, the parts still have slight deformation after correction, resulting in reduced accuracy of the parts and failure to meet actual production needs. Utility Model Content

[0005] The utility model aims to provide a correction and compensation device to solve the technical problem in the prior art that parts still have slight deformation after correction, resulting in reduced precision of the parts and failure to meet actual production needs.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a correction and compensation device, including a compensation processing table, on which a compensation seat for placing parts is provided; a fixing frame is provided on one side of the compensation seat, and the fixing frame extends upward along the height direction; a plurality of mounting plates are provided on the fixing frame along the height direction, and a compensation rod is provided on the mounting plate, and the compensation rod passes through the plurality of mounting plates along the height, and the compensation rod can move up and down along the height direction, and the compensation rod is used to suppress the parts on the compensation seat.

[0007] The principle and advantage of this scheme are: when compensating and correcting a part, the part to be corrected is placed on the compensation seat, and the deformation position on the part corresponds to the position of the correction rod; the compensation rod is moved downward so that the compensation rod squeezes the deformation position on the part to repair the deformation on the part. After the deformation repair on the part is completed, the compensation rod is moved upward to disconnect the contact between the part and the compensation rod, and the part is removed from the compensation seat. In this scheme, when repairing a part, the surface of the part is squeezed by the compensation rod, so that the deformation on the part is repaired under the action of pressure, which is convenient for the part to further repair the tiny deformation on the part after the deformation repair, and ensure the precision of the deformation repair of the part. And by passing the compensation rod through multiple mounting plates, the compensation rod can be fixed under the action of the mounting plates, ensuring the stability of the connection between the compensation rod and the fixing frame; and the central axis of the compensation rod is fixed under the action of two fixing frames, ensuring the stability of the compensation rod during the movement process, avoiding the compensation rod from offsetting during the repair process of the part, and ensuring the accuracy of the compensation repair.

When the parts are being compensated and repaired, the position of the parts can be limited by the compensation seat, so as to ensure the stability of the position of the parts during the compensation and repair, and avoid displacement of the parts during the compensation and repair process, which may cause damage to the parts.

[0009] Preferably, as an improvement, the fixing frame includes two fixing rods, which are parallel to each other and respectively penetrate the two sides of the mounting plate, so that both ends of the mounting plate are connected to the fixing frame, thereby ensuring the stability of the mounting plate connected to the fixing frame.

[0011] Preferably, as an improvement, a fixing hole is provided at one end of the mounting plate away from the fixing frame, and the fixing hole is used to connect with the compensation rod, and the compensation rod and the fixing hole are connected by threads. A triangular structure is formed between the compensation rod and the two fixing rods, which ensures the stability of the structure between the compensation rod and the fixing frame, and the distance between the compensation rod and the two fixing rods is constant, which ensures the consistency of the pressure transmitted from the fixing rod to each fixing rod during the compensation repair process, and avoids excessive pressure on one side of the fixing frame during the compensation repair process, which may cause damage to the device.

[0012] Preferably, as an improvement, a reinforcing rib is provided on the mounting plate, one end of the reinforcing rib is connected to the edge of the fixing hole, and the other end extends to the connection between the mounting plate and the fixing frame, so that the mounting plate can be strengthened under the action of the reinforcing rib, and the mounting plate can be prevented from being damaged by pressure shock during the compensation and repair process.

[0013] Preferably, as an improvement, a counterweight is provided at one end of the compensation rod away from the compensation processing table, so that during the compensation repair process, the compensation rod can smoothly move downward under the action of the counterweight, avoiding excessive pressure of the compensation rod on one side of the part, causing the thread engagement between the compensation rod and the fixing hole to slip, and causing the compensation rod to be unable to perform normal extrusion repair on the part.

[0017] As attached Figure 1 As shown, the correction and compensation device includes a compensation processing table 1, on which a fixed frame 2 is provided, and on which a compensation rod 3 for compensation processing is provided. The compensation rod 3 is used to suppress the parts placed on the compensation processing table 1 to achieve compensation processing for the deformation of the parts.

[0018] A compensation seat 101 is fixedly installed on the compensation processing table 1 by welding. The compensation seat 101 includes two compensation seats 101, which are distributed opposite to each other on the compensation processing table 1; one end of the compensation seat 101 is fixedly connected to the compensation processing table 1, and the other end extends upward along the height direction. A fixing groove 102 is provided on the top of the compensation seat 101, wherein the fixing groove 102 runs through both sides of the fixing frame 2. Preferably, in this embodiment, the fixing groove 102 is an arc groove, and the fixing groove 102 is used to place parts. When the parts are being compensated and repaired, the position of the parts can be limited by the compensation seat 101, so as to ensure the stability of the position of the parts during the compensation and repair, and avoid displacement of the parts during the compensation and repair process, which may cause damage to the parts.

[0019] One end of the fixed frame 2 is fixedly connected to the compensation processing table 1 by bolts, and the other end extends upward in the height direction; wherein the fixed frame 2 includes two fixed rods 201, and the two fixed rods 201 are parallel to each other. A plurality of mounting plates 202 are fixedly connected to the end of the fixed frame 2 away from the compensation processing table 1 by bolts, and the plurality of mounting plates 202 are distributed at intervals along the height direction on the fixed frame 2. Preferably, in this embodiment, two mounting plates 202 are fixedly connected to the fixed frame 2, and the two mounting plates 202 are parallel to each other. By arranging two mutually parallel mounting plates 202 on the fixed frame 2, the compensation rod 3 can be fixed under the action of the mounting plates 202, thereby ensuring the stability of the connection between the compensation rod 3 and the fixed frame 2; and the central axis of the compensation rod 3 is fixed under the action of the two fixed frames 2, thereby ensuring the stability of the compensation rod 3 during the movement, avoiding the compensation rod 3 from being offset during the repair process of the parts, and ensuring the accuracy of the compensation repair.

[0020] The plane where the mounting plate 202 is located is parallel to the upper surface of the compensating processing table 1, and the cross-section of the mounting plate 202 parallel to the compensating processing table 1 is an isosceles triangle. Specifically, the mounting plate 202 is a triangular prism; the two fixing rods 201 in the fixing frame 2 pass through the two corners of the mounting plate 202, and the mounting plate 202 extends toward the center of the compensating processing table 1 away from a corner of the fixing frame 2.

[0021] A fixing hole 203 is provided at one end of the mounting plate 202 away from the fixing frame 2, and a compensation rod 3 is inserted into the fixing hole 203. The central axis of the compensation rod 3 is perpendicular to the plane where the compensation processing table 1 is located, and the compensation rod 3 is projected between the two compensation seats 101; wherein threads are provided on the surface of the compensation rod 3 and the inner wall of the fixing hole 203, and the compensation rod 3 and the fixing hole 203 are connected by threads. The compensation rod 3 can move up and down along the height direction in the fixing hole 203, and the compensation rod 3 is used to perform extrusion correction on the parts on the compensation seat 101. A triangular structure is formed between the compensation rod 3 and the two fixing rods 201 to ensure the stability of the structure between the compensation rod 3 and the fixing frame 2, and the distance between the compensation rod 3 and the two fixing rods 201 is straight, so as to ensure the consistency of the pressure transmitted from the fixing rod 201 to each fixing rod 201 during the compensation repair process, and to avoid excessive pressure on one side of the fixing frame 2 during the compensation repair process, which may cause damage to the device.

[0022] A reinforcing rib 4 is also fixedly connected to the mounting plate 202 by welding, one end of the reinforcing rib 4 is connected to the edge of the fixing hole 203, and the other end extends to the connection between the mounting plate 202 and the fixing frame 2. Under the action of the reinforcing rib 4, the mounting plate 202 can improve its strength, and prevent the mounting plate 202 from being damaged by pressure shock during the compensation and repair process.

[0023] A counterweight 5 is provided at one end of the compensation rod 3 away from the compensation processing table 1.

The counterweight 5 is used to provide downward pressure to the compensation rod 3. In the compensation repair process, the compensation rod 3 can move downward smoothly under the action of the counterweight 5, so as to avoid excessive pressure on the compensation rod 3 on one side of the part, resulting in failure of the threaded engagement between the compensation rod 3 and the fixing hole 203, and the compensation rod 3 cannot normally perform extrusion repair on the part.
