Description

Technical Field

[0001] This utility model relates to the field of damper actuator technology, and in particular to a production tooling for a mounting bracket for a damper actuator. Background Technology

[0002] During operation, damper actuators, which are mostly rotary drives, are prone to swaying due to the reaction force generated by the rotational torque. Mounting brackets can fix and support the damper actuator, reducing its swaying and making its operation more stable and reliable.

[0003] In the past, the production of mounting brackets for damper actuators involved two separate processes: pressing the mounting posts into the mounting holes on the bracket and riveting the riveting parts. These processes were typically completed on different tooling or equipment. This resulted in frequent transfers of the workpiece between different devices, increasing production time and labor costs, and reducing production efficiency.

[0004] Therefore, there is a need to provide a manufacturing tooling for a mounting bracket for a damper actuator, which can integrate the pre-compression and riveting process of the bracket mounting column. Utility Model Content

The manufacturing fixture includes: a workpiece positioning assembly having a first plate and a second plate arranged opposite to each other to clamp the bracket between them, a first through hole on the first plate for placing the bracket mounting post, and a second through hole on the second plate coaxial with the first through hole; a first ejector pin, at least partially extending into the first through hole to abut the bracket mounting post placed in the first through hole; when the bracket is clamped by the first plate and the second plate, the first plate is movable relative to the first ejector pin between a first position and a second position; in the first position, the bracket mounting post is separated from the bracket, and in the second position, the bracket mounting post penetrates the mounting hole, and a riveting portion at one end of the bracket mounting post protrudes from the mounting hole; a second ejector pin, coaxially disposed in the second through hole, and movable relative to the second plate along the axial direction of the second through hole, so as to rivet the riveting portion protruding from the mounting hole after the bracket mounting post penetrates the mounting hole, thereby achieving the riveting of the bracket mounting post and the bracket.

[0008] Preferably, when the first plate moves from the first position to the second position relative to the first ejector pin, the second ejector pin retracts into the second through hole to form a clearance space for the riveting part to extend out of the mounting hole.

[0009] Preferably, the end of the riveting part has a first annular end face and a conical recess located in the inner circle of the first annular end face; the end of the second ejector pin has a second annular end face and a conical protrusion located in the inner circle of the second annular end face, corresponding to the conical recess.

[0010] Preferably, when the second ejector pin is in contact with the bracket mounting post but no interaction force is generated, the junction of the first annular end face and the conical recess is in contact with the conical surface of the conical protrusion.

[0011] Preferably, when the second ejector pin is in contact with the bracket mounting post but no interaction force is generated, the distance from the end of the conical protrusion to the bottom of the conical recess is less than the distance between the first annular end face and the second annular end face.

[0012] Preferably, when the second ejector pin is in contact with the bracket mounting post but no interaction force is generated, the angle α between the conical surface of the conical protrusion and the conical surface of the conical depression is 3-10 degrees.

[0013] Preferably, the production tooling further includes a base plate and at least two first guide posts mounted on the base plate; the first ejector pin is mounted on the base plate, and the first plate is equipped with a first guide sleeve corresponding to each of the first guide posts. The first plate is sleeved on the corresponding first guide post through the first guide sleeve to realize the movement of the first plate relative to the first ejector pin between a first position and a second position.

[0014] Preferably, the production tooling further includes a first spring coaxially sleeved on the first guide post, with both ends of the first spring abutting against the first plate and the bottom plate, respectively.

[0015] Preferably, the production tooling further includes a limiting block mounted on the base plate, wherein when the first plate is in the second position relative to the first ejector pin, the first plate abuts against the limiting block.

[0016] Preferably, the production tooling further includes a top plate and at least two second guide posts mounted on the top plate; the second ejector pin is mounted on the top plate, and the second plate is equipped with second guide sleeves corresponding to the second guide posts one by one.

[0019] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0020] In this invention, the two processes of pressing and riveting, which originally required separate workpieces or equipment, are integrated into a single tooling unit. The workpiece positioning assembly has a first plate and a second plate arranged opposite to each other, which clamp and position the bracket. The relative movement between the first ejector pin and the first plate presses the bracket mounting post into the bracket's mounting hole. Then, the relative movement between the second ejector pin and the second through hole causes the second ejector pin to rivet the protruding riveting part of the mounting hole, thus achieving the pressing and riveting of the bracket mounting post. Therefore, this design reduces the number of times the workpiece is handled and clamped between different devices, avoids errors that may arise from multiple positioning steps, shortens the production cycle, and improves production efficiency. Simultaneously, it also reduces equipment procurement costs, thereby improving production efficiency to some extent. Attached Figure Description

[0046] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0047] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0048] refer to Figures 1 to 3As shown, the damper actuator 300 is a device that drives a damper to open or close. Some damper actuators 300 are designed to require the damper's drive shaft to be inserted inside and fixed by a specific clamping device (such as a clamp) to ensure a reliable transmission connection between the two. The damper actuator 300 drives the damper's drive shaft to rotate, thereby controlling the opening and closing of the damper (see patent application publication number CN109751449A). The damper actuator mounting bracket 200 is an auxiliary device whose main function is to securely install the damper actuator 300 in a set position. Simultaneously, the bracket mounting post 100 on the mounting bracket 200 cooperates with the slot 301 on the damper actuator 300's housing to achieve a limiting function, ensuring the accuracy and stability of the damper actuator 300's installation. The mounting post, located within the slot, effectively prevents displacement or shaking of the damper actuator 300 during operation, ensuring its normal operation.

[0049] The existing valve actuators use mounting brackets 200 and mounting posts 100, all of which are manufactured using a two-step process: pressing followed by riveting. (Refer to...) Figures 1 to 9 As shown, this application provides a production tooling for a mounting bracket 200 for a damper actuator, used to press and rivet the bracket mounting column 100 onto the mounting hole 201 of the bracket 200. The production tooling mainly includes a workpiece positioning assembly 1, a first ejector pin 2, and a second ejector pin 3.

[0050] The workpiece positioning assembly 1 has a first plate 11 and a second plate 12 arranged opposite to each other to clamp the bracket 200 between them, a first through hole 13 on the first plate 11 for placing the bracket mounting post 100, and a second through hole 14 on the second plate 12 coaxial with the first through hole 13; the first ejector pin 2 extends at least partially into the first through hole 13 to abut against the bracket mounting post 100 placed in the first through hole 13; when the bracket 200 is clamped by the first plate 11 and the second plate 12, the first plate 11 can move relative to the first ejector pin 2 between a first position and a second position; in the first position, the bracket mounting post 100 is separated from the bracket 200 (e.g., ...). Figure 4 In the second position, the bracket mounting post 100 penetrates the mounting hole 201, and the riveting part 101 at one end of the bracket mounting post 100 extends out of the mounting hole 201 (e.g., Figure 7 The second ejector pin 3 is coaxially disposed in the second through hole 14 and can move relative to the second plate 12 along the axial direction of the second through hole 14 so that after the bracket mounting post 100 passes through the mounting hole 201, it can rivet the riveting part 101 extending out of the mounting hole 201, thereby realizing the riveting of the bracket mounting post 100 and the bracket 200.

[0051] In actual production, the bracket mounting column 100 is pre-placed into the first through hole 13 on the first plate 11, and the first ejector pin 2 extends into the first through hole 13 to hold or support the bracket mounting column 100. The mounting bracket 200 for the air valve actuator is also placed between the first plate 11 and the second plate 12 of the workpiece positioning assembly 1, so that the bracket mounting column 100 is coaxially aligned with the mounting hole 201. Then, the bracket 200 is clamped and fixed by the first plate 11 and the second plate 12 to ensure its stability during the processing.

[0052] With the bracket 200 clamped, the first plate 11 moves from a first position to a second position relative to the first ejector pin 2. As the first plate 11 moves, under the limiting action (or blocking action) of the first ejector pin 2, the bracket mounting post 100 and the mounting hole 201 of the bracket 200 move relative to each other, ultimately causing the bracket mounting post 100 to pass through the mounting hole 201, and the riveting part 101 at one end of the mounting post to protrude from the mounting hole 201. Because the bracket mounting post 100 needs a stable connection with the bracket 200 (because the bracket mounting post 100 needs to withstand the torque provided by the output end of the damper actuator 300, and to avoid possible loosening), the mounting post and the mounting hole 201 are in a transition fit or a slight interference fit (the operator cannot directly press the mounting post into the mounting hole by hand, but needs to use a press to press the mounting post into the mounting hole), to ensure the stability of the mounting post.

[0053] After the bracket mounting post 100 passes through the mounting hole 201, the second ejector pin 3 moves axially relative to the second plate 12 along the second through hole 14 to rivet the riveting part 101 extending out of the mounting hole 201. Through riveting, the bracket mounting post 100 and the bracket 200 are tightly connected together, completing the riveting process between the bracket mounting post 100 and the bracket 200.

[0054] In this embodiment, the two processes of pressing and riveting, which originally needed to be completed separately on different tooling or equipment, are integrated into a single tooling. The workpiece positioning assembly 1 has a first plate 11 and a second plate 12 arranged opposite to each other, which can clamp and position the bracket 200. Through the relative movement between the first ejector pin 2 and the first plate 11 (i.e., the relative sliding between the first ejector pin 2 and the first through hole 13), the bracket mounting post 100 is pressed into the mounting hole 201 of the bracket 200. Then, through the relative movement between the second ejector pin 3 and the second through hole 14, the second ejector pin 3 rivets the riveting part 101 extending out of the mounting hole 201, thereby realizing the pressing and riveting of the bracket mounting post 100. Therefore, this design reduces the number of times the workpiece is handled and clamped between different devices, avoids the errors that may be caused by multiple positioning, shortens the production cycle, and improves production efficiency. At the same time, it also reduces the equipment procurement cost and improves production efficiency to a certain extent.

[0055] Specifically, when the first plate 11 moves from the first position to the second position relative to the first ejector pin 2, the second ejector pin 3 retracts into the second through hole 14 to form a clearance space 15 for the riveting part 101 to extend out of the mounting hole 201 (e.g., Figure 7 The presence of the clearance space 15 allows the riveting part 101 to fully extend out of the mounting hole 201, enabling the second ejector pin 3 to apply sufficient pressure to the riveting part 101, thereby ensuring the riveting effect. If the riveting part 101 is blocked by the second ejector pin 3 and cannot fully extend out of the mounting hole 201 (i.e., there is no clearance space 15 or the clearance space 15 is too small for the riveting part 101 to fully extend out of the mounting hole), the riveted bracket mounting post 100 will still wobble relative to the bracket 200, causing product quality problems. It should be noted that a first limiting part 104 is generally provided on the outer wall of the bracket mounting column 100. When the first limiting part 104 abuts against the lower end of the bracket 200, the part of the bracket mounting column 100 that protrudes from the upper end of the bracket 200 is the riveting part 101. After being pressed, the riveting part 101 is riveted to the bracket 200 and combined with the first limiting part 104 to achieve a stable connection between the bracket mounting column 100 and the bracket 200. If the riveting part 101 is blocked by the second pin 3 and cannot fully extend out of the mounting hole 201, the first limiting part 104 will not abut against the lower end of the bracket 200. Therefore, in this case, the riveted bracket mounting column 100 will shake.

[0056] In some practical applications, refer to Figure 4 , Figure 7 and Figure 9 As shown, the end of the riveting part 101 has a first annular end face 102 and a conical recess 103 located in the inner circle of the first annular end face 102; the end of the second ejector pin 3 has a second annular end face 31 and a conical protrusion 32 located in the inner circle of the second annular end face 31 and corresponding to the conical recess 103.

[0057] When the first plate 11 moves from the first position to the second position, and the bracket mounting post 100 passes through the mounting hole 201 and the riveting part 101 extends out, the second ejector pin 3 moves relative to the second through hole 14 to press the riveting part 101. At this time, the tapered protrusion 32 at the end of the second ejector pin 3 aligns with the tapered recess 103 of the riveting part 101. As the second ejector pin 3 continues to apply pressure, the tapered protrusion 32 penetrates deeper into the tapered recess 103. Due to the tapered structure, the material of the riveting part 101 is squeezed outwards, allowing the riveting part 101 to be better turned outwards, gradually covering and tightly fitting the surface of the bracket 200, ultimately achieving a firm riveting.

[0058] Specifically, when the second ejector pin 3 is in contact with the bracket mounting post 100 but no interaction force is generated, the junction of the first annular end face 102 and the conical recess 103 is in contact with the conical surface of the conical protrusion 32 (e.g., Figure 9 Therefore, the size and angle of the conical surface of the conical recess 103 and the conical protrusion 32 are inconsistent, so the material of the riveting part 101 can be squeezed outwards as the second ejector pin 3 continues to apply pressure.

[0059] Specifically, refer to Figure 9 As shown, when the second ejector pin 3 is in contact with the bracket mounting post 100 but without generating an interaction force, the distance from the end of the conical protrusion 32 to the bottom of the conical recess 103 is less than the distance between the first annular end face 102 and the second annular end face 31. During the riveting process, the second ejector pin 3 has sufficient stroke to press the riveting part 101. When the second ejector pin 3 moves toward the riveting part 101, because the distance from the end of the conical protrusion 32 to the bottom of the conical recess 103 is small, the second ejector pin 3 can press the riveting part 101 relatively deeper, causing the riveting part 101 to deform sufficiently and turn outward, thereby achieving a more secure riveting. If the distance from the end of the conical protrusion 32 to the bottom of the conical recess 103 is too large, the second ejector pin 3 may not be able to apply sufficient pressure to the riveting part 101, resulting in an insecure riveting.

[0060] Specifically, refer to Figure 9 As shown, when the second ejector pin 3 is in contact with the bracket mounting post 100 but no interaction force is generated, the angle α between the conical surface of the conical protrusion 32 and the conical surface of the conical recess 103 is 3-10 degrees. If the angle α is too small, the material of the riveting part 101 will not easily be turned outward, which may result in insufficient turning and affect the firmness of the riveting; if the angle α is too large, the outer side of the conical recess 103 of the riveting part 101 may be relatively thin, causing defects such as cracks in the riveting shape.

[0061] In some practical applications, refer to Figure 3 and Figure 7 As shown, the production fixture also includes a base plate 4 and at least two first guide posts 5 mounted on the base plate 4; the first ejector pin 2 is mounted on the base plate 4, and a first guide sleeve 16 is mounted on the first plate 11. The first plate 11 is sleeved on the first guide post 5 through the first guide sleeve 16 to realize the movement of the first plate 11 relative to the first ejector pin 2 between a first position and a second position. The production fixture also includes a first spring 6 coaxially sleeved on the first guide post 5, and the two ends of the first spring 6 abut against the first plate 11 and the base plate 4, respectively. A first limiting rod 41 is also mounted on the base plate 4. The first limiting rod 41 at least partially passes through the first plate 11, and the limiting end of the first limiting rod 41 is used to limit the first plate 11 to prevent the first plate 11 from falling off the first guide post 5.

[0062] Specifically, the production fixture also includes a top plate 8 and at least two second guide posts 9 mounted on the top plate 8; the second ejector pin 3 is mounted on the top plate 8, and a second guide sleeve 17 is mounted on the second plate 12. The second plate 12 is fitted onto the second guide posts 9 through the second guide sleeve 17 to realize the movement of the second ejector pin 3 relative to the second plate 12. The production fixture also includes a second spring 10 coaxially fitted on the second guide posts 9, with its two ends abutting against the second plate 12 and the top plate 8, respectively. A second limiting rod 81 is also mounted on the top plate 8. The second limiting rod 81 at least partially passes through the second plate 12, and the limiting end of the second limiting rod 81 is used to limit the second plate 12 to prevent the second plate 12 from falling off the second guide posts 9.

[0063] The elastic coefficient of the first spring 6 is less than that of the second spring 10. From the moment the second plate 12 contacts the bracket 200 until the first plate 11 is in the second position relative to the first ejector pin 2, the compression of the second spring 10 is less than that of the first spring 6. In some practical applications, the elastic coefficient of the first spring 6 is 12 N / mm, and the elastic coefficient of the second spring 10 is 45 N / mm.

[0064] In this embodiment, the base plate 4 is fixed, and the top plate 8 is initially positioned above the base plate 4. The operator inserts the bracket mounting post 100 into the first through hole 13, and then places the bracket 200 onto the first plate 11, completing the initial positioning of the bracket 200.

[0065] The first stage of pressing down the top plate 8: The drive source of the press (which is prior art and not shown in the figure) drives the top plate 8 to move downward, and the second plate 12 moves downward along with the top plate 8. When the second plate 12 contacts the bracket 200, it continues to press down, and the second plate 12 and the first plate 11 cooperate to press the bracket 200 tightly. As the top plate 8 continues to press down, since the elastic coefficient of the first spring 6 is smaller than that of the second spring 10, the first spring 6 is more easily compressed and has a larger deformation, which causes the first plate 11 to move significantly towards the bottom plate 4. The first ejector pin 2 is fixedly installed on the bottom plate 4. The movement of the first plate 11 will cause the first ejector pin 2 to press the bracket mounting post 100 into the mounting hole 201 of the bracket 200, completing the pressing of the bracket mounting post 100.

[0066] Second stage of pressing down the top plate 8: After the first ejector pin 2 completes the pressing of the mounting post, the top plate 8 continues to press down. At this time, the deformation of the second spring 10 begins to increase, and the top plate 8 moves significantly towards the second plate 12. The top plate 8 drives the second ejector pin 3 to move, and the second ejector pin 3 performs a riveting operation on the riveting part 101, so that the bracket mounting post 100 is firmly connected to the bracket 200.

[0067] After riveting is completed, the press drive source drives the top plate 8 to move upward, and the first spring 6 and the second spring 10 release their elastic potential energy respectively. The first plate 11 and the second plate 12 gradually return to their initial positions under the action of the springs.

[0068] In this embodiment, the different elastic coefficients and compression amounts of the first spring 6 and the second spring 10 enable step-by-step force application. First, the larger deformation of the first spring 6 allows the first ejector pin 2 to smoothly press the mounting post in, and then the second spring 10 provides greater pressure for riveting, ensuring the firmness of the riveting. The entire processing only requires controlling the up and down movement of the top plate 8, which not only simplifies the operation steps but also reduces the number of drive sources, saving production and equipment costs.

[0069] In some practical applications, the production tooling also includes a limiting block 7 (such as) mounted on the base plate 4. Figure 4 and Figure 7 When the first plate 11 is in the second position relative to the first ejector pin 2, the first plate 11 abuts against the limiting block 7. The limiting block 7 ensures that the first plate 11 stops moving when the riveting part 101 of the bracket mounting post 100 is fully extended from the mounting hole 201. This allows for precise control of the depth to which the bracket mounting post 100 is pressed into the bracket 200, ensuring that the pressing depth of the bracket mounting post 100 is consistent for each product. Simultaneously, it also prevents the first plate 11 from moving excessively, preventing the first ejector pin 2 from applying excessive pressure to the bracket 200 or the bracket mounting post 100, reducing the risk of damage to the workpiece or tooling due to excessive compression.

[0070] In some practical applications, refer to Figure 4 and Figure 8 As shown above, the first plate 11 is also equipped with at least two positioning rods 18 for positioning the bracket 200. The bracket 200 has positioning holes 202 corresponding to the positioning rods 18. When the bracket 200 is positioned on the first plate 11, the mounting hole 201 is coaxial with the bracket mounting column 100. Therefore, the two positioning rods are set to ensure the accuracy of the bracket placement position, so as to achieve the coaxial distribution of the bracket mounting column 100 and the mounting hole 201.

[0071] In some practical applications, such as Figure 10 As shown, at least two guide rods 42 arranged in the same direction are also installed on the base plate 4. Each guide rod 42 passes through the top plate 8 and is slidably connected to it. The top plate 8 slides through the at least two guide rods 42 to change the distance between the top plate 8 and the base plate 4. The guide rods 42 mainly serve as guides during the movement of the top plate to ensure the positional accuracy of the top plate pressing down.

[0072] Specifically, refer to Figure 3 and Figure 4 and Figure 10As shown, the first plate 11 and the second plate 12 are both composed of two interconnected layers. Generally, the two layers are fixedly connected by bolts.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
