Description

Technical Field

[0001] This application relates to the technical field of fixing stamped parts, and in particular to a stabilizing clamp for automotive stamped parts. Background Technology

[0002] Reference Figure 1 An automotive part 01 includes two bent plates 011 with a certain distance between them. One end of the two bent plates 011 is arranged in parallel. A connecting hole 012 is opened at the parallel ends of the two bent plates 011. An inner flange 013 is provided on the inner ring wall of the connecting hole 012. The inner flange 013 is located on the side of the two bent plates 011 that are close to each other.

[0003] When processing and inspecting automotive parts, they need to be clamped and fixed. However, automotive parts made of thin metal sheets have low structural strength. If two bent plates are clamped simultaneously from both sides using a fixture, the bent plates are prone to deformation, leading to a decrease in the manufacturing precision of the automotive parts. In addition, uneven clamping force at multiple clamping points can also cause deformation of the automotive parts. Therefore, a fixture that can stably clamp automotive parts is needed. Utility Model Content

[0004] To achieve rapid and stable clamping of automotive parts, this application provides a stabilizing fixture for automotive stamping parts.

[0005] The stabilizing fixture for automotive stamping parts provided in this application adopts the following technical solution:

[0006] A stabilizing fixture for automotive stamping parts includes a mounting block and a clamping assembly. The clamping assembly is disposed on the mounting block and includes clamping rotating rods, clamping columns, and rotating shafts. Two clamping rotating rods are symmetrically arranged on the mounting block, each including a rotating part and a clamping part perpendicular to it. One rotating shaft is disposed on each of the rotating parts and is horizontally rotatably connected to the mounting block. Several clamping columns are disposed on the side of the two clamping parts that are close to each other. A vertical abutment plate is vertically disposed on the mounting block between the two clamping rotating rods. A driving assembly for driving the two clamping rotating rods to rotate is disposed on the mounting block.

[0007] By adopting the above technical solution, when clamping automotive parts, the two sides of the bent plate are inserted into the two sides of the abutment vertical plate. A drive unit drives two clamping rods to rotate around a pivot axis, moving them closer together. Clamping posts on the clamping section press the bent plate firmly against the abutment vertical plate, achieving rapid and stable clamping of the automotive parts. The abutment vertical plate, positioned between the two bent plates, supports them and reduces the possibility of deformation during clamping. Through the cooperation of the mounting block, drive assembly, and clamping assembly, the effect of rapid and stable clamping of automotive parts is achieved.

[0008] Optionally, the mounting block has an internal cavity, and a mounting base plate is connected to the bottom of the mounting block. The driving assembly includes a rotating rod, a driving eccentric roller, and abutting posts. The rotating rod is horizontally rotatably mounted on the mounting block, with one end extending out of the mounting block. The driving eccentric roller is mounted on the rotating rod and located in the internal cavity. One abutting post is horizontally mounted on each of the rotating parts, located in the internal cavity and below the driving eccentric roller. An elastic element is provided between the end of each rotating part and the mounting base plate, and the abutting post abuts against the driving eccentric roller under the action of the elastic element.

[0009] By adopting the above technical solution, when it is necessary to adjust the angle of the two clamping rotating rods, the rotating rod is turned, and the rotating rod drives the eccentric roller to rotate synchronously. The eccentric roller is driven to squeeze the two abutting posts, and the spring is compressed to accumulate elastic potential energy. Under the drive of the abutting posts, the two clamping rotating rods rotate around the rotating shaft as the central axis, thereby realizing the simultaneous driving rotation of the two clamping rotating rods.

[0010] Optionally, a support column is vertically provided on one side of the mounting block, and the rotating rod is rotatably connected to the support column. A limit rod is vertically provided on the rotating rod. When the limit rod rotates to fit against the top of the support column, the ends of the two clamping parts move away from each other.

[0011] By adopting the above technical solution, the support column supports the rotating rod, and the limiting rod is set on the rotating rod to limit the rotation stroke of the rotating rod.

[0012] Optionally, the thickness of the abutting vertical plate is equal to the distance between the two bent plates, and a snap-fit ​​arc groove is provided on one side of the abutting vertical plate, the snap-fit ​​arc groove corresponding to the shape of the inner flange.

[0013] By adopting the above technical solution, the thickness of the abutting vertical plate is equal to the distance between the two bent plates, allowing the bent plates to fit snugly against the abutting vertical plate, further reducing the possibility of deformation of the bent plates during clamping. The snap-fit ​​arc groove and the inner flange fit together, improving the structural stability when clamping automotive parts.

[0014] Optionally, the end of the abutment post is hemispherical, and one end of the abutment post is detachably connected to the clamping part via a connector.

[0015] By adopting the above technical solution, since the abutment post and the clamping part are detachably connected, an appropriate number and length of abutment posts can be installed at different positions of the clamping part according to the actual clamping needs, so that it can correspond to the different clamping needs of automotive parts.

[0016] Optionally, the rotating rod has a vertically formed linkage through hole, and the driving eccentric roller has a formed mounting through hole. The mounting through hole and the linkage through hole are connected and correspondingly arranged, and a linkage rod is inserted into both the mounting through hole and the linkage through hole.

[0017] By adopting the above technical solution, the setting of the linkage through hole, the mounting through hole, and the linkage rod enables quick and detachable assembly between the rotating rod and the driving eccentric roller.

[0018] Optionally, the elastic element is a clamping spring, and two spring mounting holes are provided on the top surface of the mounting base plate. The two spring mounting holes are provided in a one-to-one correspondence with the two clamping springs, and the bottom end of the clamping spring is provided in the corresponding spring mounting hole.

[0019] By adopting the above technical solution, the clamping spring is set between the rotating part and the mounting base plate, and the setting of the spring mounting hole facilitates the installation of the clamping spring.

[0020] Optionally, a rotating handle is provided at the end of the rotating rod.

[0021] By adopting the above technical solution, the design of the rotating handle helps users to easily rotate the rotating rod.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Through the cooperation of the mounting block, drive assembly, and clamping assembly, it can achieve the effect of fast and stable clamping of automotive parts;

[0024] 2. The snap-fit ​​arc groove and inner flange fit together, which improves the structural stability when clamping automotive parts;

[0025] 3. The design of the linkage through hole, mounting through hole, and linkage rod enables quick and easy disassembly and assembly between the rotating rod and the drive eccentric roller. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be further described in detail below. Embodiments of this application provide a stabilizing fixture for automotive stamping parts, which achieves the effect of quickly and stably clamping automotive part 01.

[0032] Reference Figure 2 and Figure 3 A stabilizing fixture for automotive stamping parts includes a mounting base plate 1, a mounting block 2, a support column 3, a clamping assembly 4, and a drive assembly 5. The mounting base plate 1 is disposed on the top surface of the mounting block 2. The mounting block 2 has an internal cavity 21, and two rotating grooves 22 are provided on opposite sides of the mounting block 2. The two rotating grooves 22 are connected to the internal cavity 21.

[0033] Reference Figure 3 and Figure 4The clamping assembly 4 is mounted on the mounting block 2. The clamping assembly 4 includes a clamping rotating rod 41, a rotating shaft 42, a clamping column 43, an abutting vertical plate 44, and a clamping spring 45. The clamping rotating rod 41 includes a rotating part 411 and a clamping part 412 vertically disposed at one end of the rotating part 411. The two clamping rotating rods 41 are disposed in the same vertical plane. One rotating shaft 42 is disposed on each rotating part 411, and the direction of the rotating shaft 42 is perpendicular to the vertical plane containing the clamping rotating rod 41. The rotating shaft 42 is rotatably connected to the mounting block 2, and the rotating part 411 extends out of the mounting block 2 through a rotating groove 22.

[0034] Reference Figure 3 and Figure 2 Several clamping columns 43 are bolted to each other on the side of the two clamping parts 412 that are close to each other. The end of the abutment column 52 is hemispherical. A support base plate 6 is provided at the top of the mounting block 2. The abutment vertical plate 44 is vertically set on the support base plate 6 and is set between the two clamping parts 412. The setting direction of the abutment vertical plate 44 is perpendicular to the setting direction of the rotation shaft 42. The thickness of the abutment vertical plate 44 is equal to the distance between the parallel parts of the two bent plates 011. A snap-fit ​​arc groove 441 is opened on one vertical side of the abutment vertical plate 44. The shape of the snap-fit ​​arc groove 441 corresponds to the shape of the inner flange 013.

[0035] Reference Figure 3 The drive assembly 5 includes a rotating rod 51, an abutment post 52, a rotating handle 53, a rotating shaft 42 bearing, a linkage rod 55, a drive eccentric roller 56, and a limiting rod 57. The rotating rod 51 is horizontally rotatable on the mounting block 2 via the rotating shaft 42 bearing. A portion of the rotating rod 51 is disposed within the receiving cavity 21, and a portion extends out of the mounting block 2. The end of the rotating rod 51 extending out of the mounting block 2 is connected to the rotating handle 53. A linkage through hole 511 is vertically formed on the rod segment of the rotating rod 51 located within the receiving cavity 21. The drive eccentric roller 56 is sleeved on the rotating shaft 42, and a mounting through hole 561 is formed on the drive eccentric roller 56. The mounting through hole 561 and the linkage through hole 511 are connected and correspondingly arranged. The linkage rod 55 is inserted into both the mounting through hole 561 and the limiting through hole 512.

[0036] Reference Figure 3 and Figure 4One abutment post 52 is horizontally connected to each rotating part 411, and two abutment posts 52 are located on the side of the two rotating shafts 42 that are close to each other. One clamping spring 45 is connected to the bottom end of each rotating part 411. Two spring mounting holes 101 are provided on the top surface of the mounting base plate 1, and the two spring mounting holes 101 are correspondingly arranged with the two clamping springs 45. The bottom end of the clamping spring 45 is connected to the inner bottom wall of the spring mounting hole 101. In its natural state, the abutment post 52 is pressed against the bottom end of the drive eccentric roller 56 under the action of the clamping spring 45. When the drive eccentric roller 56 rotates to a certain angle, the clamping posts 43 on the two clamping parts 412 are pressed against the opposite sides of the abutment vertical plate 44.

[0037] Reference Figure 3 A support column 3 is located on one side of the mounting block 2 and is rotatably connected to the rotating rod 51. A support groove 31 for supporting the rotating rod 51 is provided on the top surface of the support column 3. A limiting through hole 512 is vertically provided on the rotating rod 51, and a limiting rod 57 is inserted into the limiting through hole 512, with one end of the limiting rod 57 extending out of the limiting through hole 512. When the rotating rod 51 rotates until the limiting rod 57 abuts against the top of the support column 3, the two clamping rotating rods 41 are in the unfolded position.

[0038] Reference Figure 2-4 When clamping the automotive part 01, the abutment vertical plate 44 is inserted into the opposite sides of the abutment vertical plate 44, and the inner flange 013 is made to fit against the inner wall of the snap-fit ​​arc groove 441. Turning the handle 53 causes the rotating rod 51 to rotate, and the drive eccentric roller 56 mounted on the rotating rod 51 rotates. When the abutment post 52 is pressed down by the drive eccentric roller 56, the spring 45 is compressed and accumulates elastic potential energy. The two clamping parts 412 rotate towards each other as the rotating part 411 rotates, until the clamping post 43 presses the bent plate 011 tightly against the opposite sides of the abutment vertical plate 44, thus achieving stable clamping of the automotive part 01.

[0039] Reference Figure 3 and Figure 4 The linkage through hole 511, mounting through hole 561, and linkage rod 55 facilitate quick installation and disassembly between the rotating rod 51 and the drive eccentric roller 56. The limiting rod 57 limits the rotational stroke of the rotating rod 51. The spring mounting hole 101 facilitates the installation of the clamping spring 45. Because the clamping column 43 is detachably connected to the clamping part 412, the operator can install a specific number of clamping columns 43 at different positions on the clamping part 412 as needed. The abutment vertical plate 44 supports the two bent plates 011, reducing the possibility of deformation of the two bent plates 011 during clamping. The snap-fit ​​arc groove 441 helps improve the connection stability between the automotive part 01 and the abutment vertical plate 44.

[0040] Reference Figure 2 and Figure 4 After processing the automotive part 01, the handle 53 is rotated in the opposite direction, causing the spring 45 to extend and driving the two clamping rods 41 to rotate in the opposite direction around the rotating shaft 42. The clamping column 43 separates from the bending plate 011, releasing the lock on the automotive part 01.

[0041] The implementation principle of a stabilizing fixture for automotive stamping parts in this embodiment is as follows: When clamping automotive part 01, the abutting vertical plate 44 is inserted into the opposite sides of the abutting vertical plate 44, and the inner flange 013 is made to fit against the inner wall of the snap-fit ​​arc groove 441. By turning the handle 53, the two clamping parts 412 rotate towards each other as the rotating part 411 rotates, until the clamping column 43 presses the bent plate 011 tightly against the opposite sides of the abutting vertical plate 44, thus achieving stable clamping of automotive part 01.

[0042] The abutment vertical plate 44 supports the two bent plates 011, reducing the possibility of deformation of the two bent plates 011 during clamping. The snap-fit ​​arc groove 441 helps to improve the connection stability between the automotive part 01 and the abutment vertical plate 44.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
