Description

Technical Field

[0001] This invention relates to the field of parts processing equipment technology, and in particular to a comprehensive processing device for a middle support joint. Background Technology

[0002] The center bracket joint is a key component in automobiles, mainly used to support and fix important components such as axles and suspension systems, ensuring the function and performance of these important components during vehicle operation. This is crucial for ensuring the safety performance of automobiles, therefore, designing a center bracket joint is of great significance.

[0003] The main body of the middle support connector is a U-shaped structure. A first through hole and a second through hole are provided at both ends of the U-shaped body. The two first through holes are coaxial, and the axis of the second through hole is perpendicular to the first through hole. The middle support connector is formed by casting. The cast blank needs to be machined. The machining of the middle support connector includes machining the inner surfaces at both ends of the U-shaped body, machining the two outer surfaces at the bottom of the U-shaped body, machining the first and second through holes, and machining the cuts at the ends of the body. The length, width, and height of the middle support joint are 130mm, 100mm, and 100mm, respectively. Due to its small size, compact structure, and numerous machining points, the existing technology for machining the middle support joint mainly uses the second through hole as the positioning reference. As a result, only one machining point can be machined at a time, and other machining points are obstructed by the clamping. Therefore, each machining point requires a set of machining fixtures, and five sets of machining fixtures are needed to complete the machining of one middle support joint. This method not only requires multiple clamping and workpiece transport, which is time-consuming, labor-intensive, and inefficient, but also makes it difficult to guarantee the machining accuracy of the product, especially the parallelism between the inner and outer surfaces and the perpendicularity between the first through hole and the inner and outer surfaces. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a comprehensive processing device for intermediate support joints. This device is rationally designed, easy to use, and can process multiple points of the intermediate support joint in a single clamping, thereby improving processing efficiency and ensuring product quality.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a comprehensive processing device for a middle support joint, including a base, a fixed support block and a movable support block arranged above the base, the fixed support block being fixedly connected to the base, the movable support block being slidably connected to the base via a first slide rail, the movable support block being provided with a driving device for driving the movable support block to slide, the fixed support block and the movable support block being symmetrically arranged, the fixed support block and the movable support block being provided with inclined surfaces for forming a V-shape, the inclination angle of the inclined surfaces of the fixed support block and the movable support block being consistent with the inclined surface A of the middle support joint, a connecting arm being arranged above the fixed support block and the movable support block, a rotatable rolling device being arranged at the free end of the connecting arm, an abutting arm being arranged below the connecting arm, and a limit device being arranged on the inner side of the inclined surface of the fixed support block.

[0006] Furthermore, after the middle support joint is fixed above the fixed support block and the moving support block, the connecting arm, roller and abutting arm are located above the inclined surface B of the middle support joint and below the second through hole of the middle support joint.

[0007] Furthermore, after the middle support joint is fixed above the base, the outer sides of the fixed support block and the movable support block do not extend beyond the outer side of the middle support joint, and the inner sides of the upper part of the fixed support block and the movable support block do not extend beyond the inner side of the upper end of the U-shape of the middle support joint.

[0008] Furthermore, the driving device includes a driving block and a screw. The driving block is fixedly connected to the moving support block, and the screw is threadedly connected to the base. The screw passes through the base and is rotatably connected to the driving block.

[0009] Furthermore, a lifting mechanism is provided above the base, and the lifting mechanism is located between the moving support block and the fixed support block.

[0010] Furthermore, the lifting mechanism includes a top rod and a push rod. The bottom of the top rod is rotatably connected to the base, and one end of the push rod is hinged to the top rod, while the other end is hinged to the drive device.

[0011] Furthermore, the rolling device is a bearing, a roller, or a wheel.

[0012] The beneficial effects of this invention are as follows: the inclined surfaces of the fixed support block and the movable support block cooperate with the inclined surface A of the middle support joint. Under the squeezing action of the movable support block, the middle support joint moves upward along the inclined surface. At the same time, under the action of the upper connecting arm and the rolling device, the middle support joint is kept moving upward, avoiding deviation and tilting. Under the combined action of the upper abutment arm, the lower inclined surface squeezing, and the limiting device, the lower part of the middle support joint is firmly clamped, realizing the clamping and fixing of the workpiece. In addition, after the middle support joint is clamped and fixed, all the machining points of the middle support joint can be exposed without affecting the machining of any one machining point. All points can be machined in one clamping, improving production efficiency and ensuring the machining accuracy of the product. Attached Figure Description

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment of a comprehensive processing device for a middle support joint includes a base 1. A fixed support block 2 and a movable support block 3 are disposed above the base 1. Preferably, there are two fixed support blocks 2 and two movable support blocks 3, used to support the inclined surfaces A51 on both sides of the lower part of the middle support joint 5. The fixed support blocks 2 are fixedly connected to the base 1, and the movable support blocks 3 are slidably connected to the base 1 via a first slide rail. Each movable support block 3 is provided with a driving device 4 for sliding. The fixed support blocks 2 and 3 are symmetrically arranged, and each fixed support block 2 and 3 has inclined surfaces for forming a V-shape. The inclination angle of the inclined surfaces of the fixed support blocks 2 and 3 is consistent with the inclined surface A51 of the middle support joint 5. A connecting arm 6 is disposed above the fixed support blocks 2 and 3, and a rotatable rolling device 7 is disposed at the free end of the connecting arm 6. The middle support joint 5... When moving upwards, the rolling device 7 provides support to prevent the workpiece from tilting and reduces the frictional resistance between the workpiece and the connecting arm 6. A contact arm 8 is located below the connecting arm 6, perpendicular to the inclined surface B52 of the middle support joint 5. A limiting device 9 is provided on the inner side of the inclined surface of the fixed support block 2. The limiting device 9 can be a limiting block or a limiting post. The limiting device 9 can contact the inner side of the lower part of the middle support joint 5, thereby restricting the position of the middle support joint 5 and preventing the workpiece of the middle support joint 5 from moving during the processing of the first through hole and notch. After the middle support joint 5 is fixed above the fixed support block 2 and the moving support block 3, the connecting arm 6, the roller, and the contact arm 8 are located above the inclined surface B52 of the middle support joint 5 and below the second through hole of the middle support joint 5. The end of the contact arm 8 abuts against the inclined surface B52 of the middle support joint 5.

[0024] In use, the U-shaped opening of the middle support joint 5 is placed between the fixed support block 2 and the movable support block 3 with the U-shaped opening facing upward. The inclined surface A51 of the middle support joint 5 cooperates with the inclined surfaces of the fixed support block 2 and the movable support block 3. The limiting device 9 contacts the inner side of the lower part of the middle support joint 5, and the rolling device 7 contacts the upper two ends of the middle support joint 5. The driving device 4 drives the movable support block 3 to move towards the fixed support block 2. Under the squeezing force of the movable support block 3, the middle support joint 5 moves upward along the inclined surfaces of the fixed support block 2 and the movable support block 3. At the same time, since the rolling device 7 contacts the upper two sides of the middle support joint 5, after moving upward, the abutting arm 8 can abut against the inclined surface B52 of the middle support joint 5. Therefore, it can be ensured that the middle support joint 5 moves upward in the positive direction until the middle support joint 5 abuts against the abutting arm 8 to achieve the clamping and fixing of the workpiece. The fixed workpiece will not be skewed, effectively ensuring the processing accuracy of the workpiece. After the middle support joint 5 is fixed, the processing mechanisms such as the milling plane mechanism, the first through hole processing mechanism, the second through hole processing mechanism, and the notch cutting mechanism respectively process each processing point of the workpiece.

[0025] Specifically, the base 1 is installed on the worktable of the machine frame. The worktable is equipped with horizontal and vertical slide rails. The ends of the horizontal and vertical slide rails are respectively equipped with a milling plane mechanism, a first through hole processing mechanism, a second through hole processing mechanism, and a notch cutting mechanism. The milling plane mechanism, the through hole processing mechanism, and the notch cutting mechanism are all existing workpiece processing equipment. The notch of the middle support joint 5 is located above the second through hole, and its length direction is consistent with the axis of the second through hole. The milling plane mechanism is equipped with four parallel milling discs, which can simultaneously process the upper inner plane and the lower outer plane of the middle support joint 5.

[0026] After the middle support joint 5 is fixed above the base 1, the outer sides of the fixed support block 2 and the movable support block 3 do not extend beyond the outer side of the middle support joint 5, and the inner sides of the upper part of the fixed support block 2 and the movable support block 3 do not extend beyond the inner side of the upper end of the U-shape of the middle support joint 5. This avoids the clamping of the fixed support block 2 and the movable support block 3 on the workpiece affecting the milling of the plane of the middle support joint 5, and helps to ensure the milling mechanism can process the inner side of the upper part and the outer side of the lower part of the middle support joint 5.

[0027] The driving device 4 includes a driving block 41 and a screw 42. The driving block 41 is fixedly connected to the moving support block 3, and the screw 42 is threadedly connected to the base 1. The screw 42 passes through the base 1 and is rotatably connected to the driving block 41. By rotating the screw 42, the driving block 41 is pushed to move, which simultaneously drives the moving support block 3 to slide along the first slide rail, thereby realizing the clamping and fixing of the centering bracket joint 5.

[0028] A lifting mechanism 10 is provided above the base 1, located between the movable support block 3 and the fixed support block 2. After the middle support joint 5 is placed above the fixed support block 2 and the movable support block 3, the lifting mechanism 10 is located below the middle support joint 5. The lifting mechanism 10 includes a top rod 101 and a push rod 102. The bottom of the top rod 101 is rotatably connected to the base 1, and one end of the push rod 102 is hinged to the top rod 101, while the other end is hinged to the drive device 4. A roller or wheel is provided at the top of the top rod 101. When the movable support block 3 moves along the first slide rail towards the fixed support block 2, and the middle support joint 5 is squeezed upward, the lifting mechanism 10 can provide an upward thrust to the bottom of the middle support joint 5, ensuring the smooth upward movement of the middle support joint 5, thereby clamping and fixing the middle support joint 5. Preferably, the end of the push rod 102 is connected to the movable support block 3, so that the lifting mechanism 10 can move synchronously with the movable support block 3. That is, when the movable support block 3 moves closer to the fixed support block 2, the middle support joint 5 is clamped, and the push rod 102 moves synchronously towards the fixed support block 2, generating a thrust on the top rod 101, causing the end of the top rod 101 to gradually rise, thereby pushing the middle support joint 5 upward; when the movable support block 3 moves away from the fixed support block 2, the push rod 102 moves synchronously with the movable support block 3, causing the top rod 101 to tilt and release the action on the workpiece.

[0029] The rolling device 7 is a bearing, a roller, or a wheel. The rolling device 7 can guide the middle support joint 5 to move upward while reducing the friction between it and the workpiece.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
