Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, specifically to an assembly equipment for pipe fittings. Background Technology

[0002] Aluminum / magnesium alloy die castings offer advantages such as lightweight and high strength, and are widely used in industries such as automotive parts. After machining, aluminum / magnesium alloy die castings generally need to be assembled with other components to form a usable product.

[0003] In some aluminum / magnesium alloy die-casting products, they need to be assembled with various pipe fittings. For example, the die-casting of the electrical control box of an automotive battery pack contains water-cooled channels for cooling various electronic control components, and the die-casting of the electrical control box also has inlet and outlet ports for the water-cooled channels. After the die-casting of the electrical control box is completed, inlet and outlet water pipe connectors need to be inserted into the inlet and outlet ports of the water-cooled channels to facilitate piping connection with the cooling water circulation system. Another example is the die-casting of a water pump base, which has inlet and outlet water holes. After the die-casting of the water pump base is completed, inlet and outlet water pipes need to be installed into the inlet and outlet water holes to ensure that it can be connected to the water supply and drainage system.

[0004] To improve the assembly quality with the corresponding die-cast orifice, inlet and outlet pipes and other fittings must ensure their centerlines are aligned with the orifice's centerline during insertion. In existing technology, the die-cast part is fixed to the product fixture of the pipe fitting machine, while the fitting is fixed to the pressing section of the machine. The pressing section moves linearly along the assembly direction (generally the pipe centerline direction), pushing the fitting into the corresponding orifice of the die-cast part. This structural configuration makes aligning the fitting's centerline with the die-cast orifice's centerline cumbersome and difficult. Even if centerline alignment is achieved initially, cumulative errors can easily occur during long-term processing, causing the fitting's centerline to deviate from the die-cast orifice's centerline. When the fitting and die-cast orifice's centerlines are misaligned, localized excessive extrusion can damage the outer wall of the fitting and the inner wall of the die-cast orifice, potentially leading to fitting deformation and slight bending, thus reducing assembly quality. Utility Model Content

[0005] To improve the assembly quality of pipe fittings and die-cast parts orifices, this utility model provides a device capable of adaptively and micro-adjusting the position of the pipe pressing section of a pipe fitting machine. The main technical solution adopted is as follows:

[0006] A floating adjustment device for the pipe pressing section of a pipe loading machine, the key feature of which is: it includes a base plate and a floating seat, wherein the floating seat is linearly slidably mounted on the base plate;

[0007] Two blocks are fixed on the base plate, and the two blocks are distributed along the linear sliding direction of the floating seat;

[0008] A limit block is fixed on the floating seat, and a portion of the limit block is located between the two stops.

[0009] Each of the two stops is equipped with an adjustable elastic component, which faces and contacts the limiting block. The limiting block floats and switches positions when pushed by the adjustable elastic component.

[0010] The base plate is fixed on the straight pipe pressing section of the pipe assembly machine. A pipe clamping mechanism is installed on the floating seat. The pipe to be assembled is positioned on the pipe clamping mechanism, and the die-cast part is fixed on a special fixture. In the early stages of assembly, the base plate needs to be positioned appropriately so that the corresponding orifices on the die-cast part are roughly aligned with the pipe to be assembled. Then, the adjustable elastic components on the two stops need to be adjusted to achieve a more precise alignment between the corresponding orifices on the die-cast part and the pipe to be assembled. Finally, the production process begins. During the assembly of the pipe and orifice, even if the centerline of the die-cast part's orifice is not perfectly aligned with the centerline of the pipe to be assembled, the pipe will adaptively adjust its position (based on the floating seat) due to uneven force on its outer wall, thus realigning the pipe and orifice centerlines. This structure prevents damage to the outer wall of the pipe and / or the inner wall of the die-cast part's orifice, avoids pipe deformation and bending, and improves assembly quality.

[0011] The adjustable elastic component is used to keep the floating seat (including the pipe clamping mechanism and the pipe) in a relatively precise alignment position and to cooperate with the floating seat for adaptive and precise alignment. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0022] Example 1:

[0023] like Figure 2 , 3 As shown in Figure 4, a floating adjustment device for the pipe pressing section of a pipe loading machine includes a base plate 1 and a floating seat 2. The floating seat 2 is linearly slidably mounted on the base plate 1 via two linear slide rail assemblies. The sliding directions of the two linear slide rail assemblies are parallel to each other, the guide rails of the linear slide rail assemblies are fixed on the base plate 1, and the floating seat 2 is fixed on the slider of the linear slide rail assembly.

[0024] Two blocks 11 are fixed on the base plate 1, and the two blocks 11 are distributed along the linear sliding direction of the floating seat 2; the blocks 11 are preferably L-shaped; one arm of the blocks 11 is fixed to the base plate 1, and the other arm of the blocks 11 extends toward the floating seat 2.

[0025] A limiting block 21 is fixed on the floating seat 2, and a part of the limiting block 21 is located between the two stops 11. The limiting block 21 is preferably T-shaped, and the lateral part of the limiting block 21 is fixedly connected to the floating seat 2. The longitudinal part of the limiting block 21 extends to the support arm between the two stops 11.

[0026] Each of the stop blocks 11 is equipped with an adjustable elastic component 3 and a stop screw 4. Specifically, the adjustable elastic component 3 and the stop screw 4 are located on the extended support arm of the stop block 11.

[0027] The adjustable elastic component 3 is directed toward and in contact with the limiting block 21, and the limiting block 21 is pushed by the adjustable elastic component 3 to float and switch positions.

[0028] A specific embodiment of an adjustable elastic component 3 is as follows: the adjustable elastic component 3 includes an adjusting stud 31 and a push spring 32;

[0029] The length direction of the adjusting stud 31 is parallel to the linear sliding direction of the floating seat 2. The adjusting stud 31 is threadedly assembled with the corresponding stop block 11. Both ends of the adjusting stud 31 pass through the corresponding stop block 11. A torsion block 33 is fixedly provided at the outer end of the adjusting stud 31.

[0030] The push spring 32 is fitted onto the adjusting stud 31 inside the stop block 11. One end of the push spring 32 contacts and abuts against the stop block 11, and the other end contacts and abuts against the limiting block 21. Since each stop block 11 is equipped with an adjustable elastic component 3, the floating seat 2 is simultaneously acted upon by the adjustable elastic components 3 on both sides. By rotating the adjusting studs 31 on both sides of the floating seat 2, the floating seat 2 can be adjusted and maintained in a relatively precise alignment position. The floating seat 2 is used to fix the pipe fitting to be assembled. Guide chamfers can be configured at the insertion end of the pipe fitting and the outer end of the orifice. When the pipe fitting is inserted towards the orifice, the floating seat 2 can adaptively move according to the force on the outer wall of the pipe fitting, thereby achieving automatic alignment between the pipe fitting and the center line of the orifice. This avoids damage to the outer wall of the pipe fitting and / or the inner wall of the die-casting orifice, prevents bending deformation of the pipe fitting, and thus improves assembly quality.

[0031] To improve the stability of the push spring 32, a spring receiving cavity 21a is provided on the limiting block 21 corresponding to the push spring 32. One end of the push spring 32 is located in the spring receiving cavity 21a, and the inner end of the adjusting stud 31 faces the spring receiving cavity 21a.

[0032] The length direction of the stop screw 4 is parallel to the linear sliding direction of the floating seat 2. The stop screw 4 is threadedly assembled with the corresponding stop block 11. Both ends of the stop screw 4 extend out of the stop block 11, and the inner end of the stop screw 4 faces the limiting block 21. The outer end face of the stop screw 4 is provided with an internal hex wrench hole. The stop screw 4 is used to limit the maximum linear movement range of the corresponding floating seat 2, so as to avoid excessive shaking of the floating seat 2 caused by the operation of the equipment.

[0033] Example 2:

[0034] like Figure 2-9 As shown, a multi-directional floating adjustment system for the pipe pressing section of a pipe loading machine includes two floating adjustment devices for the pipe pressing section of the pipe loading machine as described in Embodiment 1. The two adjustment devices are arranged sequentially in the vertical direction. The floating seat 2 of the upper adjustment device is fixedly connected to the base plate 1 of the lower adjustment device. In a preferred embodiment, the floating seat 2 of the upper adjustment device and the base plate 1 of the lower adjustment device are fixedly connected as a whole.

[0035] The linear sliding directions of the floating seats 2 of the two adjustment devices are perpendicular to each other. Preferably, the linear sliding directions of the floating seats 2 of both adjustment devices are horizontal, and these directions are perpendicular to each other. The two adjustment devices constitute a two-dimensional planar floating system, enabling adaptive adjustment of the position (of the floating seat 2 of the lower adjustment device) in the horizontal plane.

[0036] The base plate 1 is vertically slidably mounted on the tube mounting base. The base plate 1 is connected to a vertical tube pressing cylinder, the piston rod of which is fixedly connected to the base plate 1 to drive it to move up and down. A tube holding fixture A is fixed on the floating seat 2 of the lower adjustment device. The tube holding fixture A forms the tube pressing part.

[0037] The pipe holding fixture A includes a pipe holding base A1, on which a rotation displacement assembly A2 is disposed. The rotation displacement assembly A2 includes a fixed part A21 and a rotating part A22. The fixed part A21 is fixedly connected to the pipe holding base A1, and the rotating part A22 is rotatably disposed on the fixed part A21. The rotation center line of the rotating part A22 is set horizontally.

[0038] A preferred embodiment is that the rotational positioning component A2 is a rotary cylinder, the cylinder barrel of the rotary cylinder forms the fixed part A21, and the output shaft of the rotary cylinder forms the rotating part A22. A further preferred embodiment is that the rotational positioning component A2 is a rack and pinion rotary cylinder.

[0039] Of course, the rotational displacement component A2 can also be a servo motor.

[0040] The rotating part A22 is equipped with a gripper mechanism A3. The gripper mechanism A3 includes an execution component A31 and two clamping plates A32. The two clamping plates A32 are respectively mounted on the execution component A31. The execution component A31 drives the two clamping plates A32 to move closer or further away from each other.

[0041] The two clamping plates A32 have tube-holding cavities on their opposite sides.

[0042] The gripper mechanism A3 is the effective component for holding the pipe fitting to be assembled. The rotation and positioning assembly A2 rotates the gripper mechanism A3 to different positions. When the two clamping plates A32 rotate to the horizontal position, it is the pipe placement position. At this time, the pipe holding cavity is also configured to face horizontally, providing good visibility and facilitating the quick placement of the pipe fitting. Simultaneously, the worker can place the pipe fitting on the lower clamping plate and then proceed with other preparatory work. Therefore, this type of pipe holding assembly can accelerate the production pace of pipe insertion. When the two clamping plates A32 rotate to the vertical position, it is the pipe insertion position. At this time, the pipe holding cavity is also configured to face vertically downwards to cooperate with the longitudinally placed automotive battery control box for pipe insertion.

[0043] The actuator A31 is preferably a finger cylinder, the cylinder barrel of which is fixedly connected to the rotating part A22, and the two grippers of the finger cylinder are respectively fixedly connected to the clamping plate A32.

[0044] To make the two clamping plates A32 more stable when they are close to each other, the two clamping plates A32 are also provided with a clamping plate stabilizing assembly A4, which includes a tensioning column A41 and a pressing pin A42.

[0045] For ease of explanation: either of the clamping plates A32 will be named the tensioning clamping plate, and the other clamping plate A32 will be named the pressing clamping plate;

[0046] One end of the tensioning column A41 is fixed to the inner side of the tensioning clamping plate, and a clamping pin insertion hole is provided at the free end of the tensioning column A41; a clearance through hole is provided on the clamping clamping plate corresponding to the tensioning column A41, and the actuating component A31 drives the clamping plate to move along the tensioning column A41; a telescopic component A5 is fixedly disposed on the outer side of the clamping plate, and the telescopic part of the telescopic component A5 is fixedly connected to the clamping pin A42;

[0047] When the rotational positioning component A2 rotates the two clamping plates A32 to a horizontal pipe-laying position, the telescopic part of the telescopic component A5 remains in a retracted state, and the clamping pin A42 also remains in a retracted state. The execution component A31 moves the two clamping plates A32 away from each other, and the worker places the pipe to be assembled into the holding cavity on the lower clamping plate A32. Then, the execution component A31 moves the two clamping plates A32 closer together and clamps the pipe to be assembled. At this time, the free end of the tensioning column A41 extends to the outside of the clamping plate, and the telescopic part of the telescopic component A5 extends, driving the clamping pin A42 into the clamping pin insertion hole. The tensioning column A41 and the clamping pin A42 cooperate to further tighten / compress the two clamping plates A32 to maintain the clamping stability of the two clamping plates A32 for the pipe to be assembled. Afterwards, the rotational positioning component A2 rotates the two clamping plates A32 to a vertical pipe-insertion position for pipe-insertion operation.

[0048] After the insertion operation is completed, the telescopic part of the telescopic component A5 drives the clamping pin A42 to retract synchronously, contacting the connection between the clamping pin A42 and the tensioning column A41. The execution component A31 then drives the two clamping plates A31 to move away from each other and loosen the pipe to be assembled. The rotation displacement component A2 then drives the two clamping plates A32 to rotate back to the horizontal pipe laying position for the next round of operation.

[0049] The telescopic component A5 is preferably a telescopic cylinder, and the clamping pin A42 is fixedly connected to the free end of the piston rod of the telescopic cylinder.

[0050] In order to control the rotation angle of the rotation displacement assembly A2 and switch the clamping plate A32 between the tube placement position and the tube insertion position, a rotation limiting block A23 is fixed on the fixed part A21, and an angle limiting stop bar A24 is fixed on the rotating part A22. When the rotating part A22 rotates, it rotates into position as the angle limiting stop bar A24 abuts against the rotation limiting block A23.

[0051] To facilitate the insertion of the clamping pin A42, the free end of the clamping pin A42 is provided with a guide chamfer. A wear-resistant ring A43 is fixedly nested inside the clamping pin insertion hole to improve service life.

[0052] Beneficial effects: The floating seat used to fix the pipe fitting to be assembled can adaptively move according to the force on the outer wall of the pipe fitting, thereby automatically aligning the center line of the pipe fitting with the center line of the die-cast part's orifice. This avoids damage to the outer wall of the pipe fitting and / or the inner wall of the die-cast part's orifice, prevents bending deformation of the pipe fitting, and thus improves assembly quality.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
