Description

Technical Field

[0001] This utility model relates to the field of balance plate pressure fixture technology, and in particular to a multi-station clamping and flipping fixture. Background Technology

[0002] In automotive parts, the balance disc pressure plate is primarily used to ensure the balance and stability of related automotive components. During the machining of the balance disc pressure plate, due to its complex shape and structure with multiple curved surfaces and through holes, multi-directional limiting methods are typically used to clamp the product during mounting to achieve positioning. Commonly available limiting fixtures are mostly used for clamping and limiting single parts. After machining one part, the new part needs to be disassembled and clamped, resulting in low work efficiency. Utility Model Content

[0003] In response to the shortcomings of the existing production technology, the applicant provides a multi-station clamping and flipping fixture with a reasonable structure. Multiple sets of clamps are provided on both sides of the flipping plate, which can clamp multiple parts at once and improve work efficiency.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A multi-station clamping and flipping fixture includes a support base and a flipping plate rotatably connected to the support base. The support base has a built-in power source, and the flipping plate is equipped with fixtures on both sides.

[0006] The tooling includes:

[0007] The positioning base is located on the flip plate.

[0008] The downward-pressing cylinder is located on the tilting plate.

[0009] The pneumatic support cylinder is tilted and mounted on the tilting plate.

[0010] The downward pressure cylinder applies a pressure limiting force perpendicular to the flip plate to the part, while the pneumatic support cylinder applies an additional resistance limiting force inclined to the flip plate.

[0011] As a further improvement to the above technical solution:

[0012] A cylinder seat is provided between the bottom of the pressing cylinder and the tilting plate. The height of the cylinder seat is used to compensate for the lifting height of the cylinder piston rod.

[0013] A wedge seat is provided between the bottom of the pneumatic support cylinder and the tilting plate, and the pneumatic support cylinder is located on the wedge surface of the wedge seat.

[0014] The piston rod end of the pneumatic support cylinder abuts against any step of the part.

[0015] The tooling layout on both sides of the flip plate is exactly the same.

[0016] The tooling is arranged on one side of the flip plate, and the two pieces are arranged alternately.

[0017] When the part is clamped, the bottom surface of the part is parallel to the thickness surface of the flip plate.

[0018] The flip plate can flip 180° in a single rotation.

[0019] The flip plate includes a flipping end and a driven end, with the flipping end connected to a power source inside the support base.

[0020] The tooling on one side of the flip plate is clamped synchronously.

[0021] The beneficial effects of this utility model are as follows:

[0022] The multi-station clamping and flipping fixture provided in this application integrates multiple sets of fixtures on both sides of the flipping plate. After the part clamped by one side of the fixture is processed, it is flipped 180° by the flipping plate, and the part to be processed on the other side is located on the processing position, which greatly increases the number of parts that can be limited in a single clamping.

[0023] The clamping action in this application mainly uses a cylinder and a pneumatic support cylinder to limit the position of the part. The pneumatic support cylinder uses a continuous airflow to push the piston into place and support the workpiece. It can be tilted. In this application, for the special shape of the part, the cylinder applies pressure vertically and the pneumatic support cylinder tilts to limit the position. Only two pressure points are needed to complete the limiting of a part, and the whole process is automatic, greatly reducing the amount of manual work.

[0024] The flip plate in this application has clamps arranged in an alternating angle on each side, which is reasonable and allows more sets of clamps to be installed on a single flip plate. Attached Figure Description

[0037] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0038] like Figures 1-9 As shown, the multi-station clamping and flipping fixture 3 of this embodiment includes a support base 1 and a flipping plate 2 rotatably connected to the support base 1. The support base 1 has a built-in power source, and the flipping plate 2 is equipped with fixtures 3 on both sides.

[0039] Tooling 3 includes:

[0040] Positioning seat 301 is mounted on the flip plate 2.

[0041] The downward pressing cylinder 302 is mounted on the tilting plate 2.

[0042] The pneumatic support cylinder 303 is tilted and mounted on the tilting plate 2.

[0043] The downward pressure cylinder 302 applies a pressure limiting force perpendicular to the flip plate 2 to the part, and the pneumatic support cylinder 303 applies an additional resistance limiting force inclined to the flip plate 2.

[0044] A cylinder seat 304 is provided between the bottom of the pressing cylinder 302 and the flip plate 2. The height of the cylinder seat 304 is used to compensate for the lifting height of the cylinder piston rod.

[0045] A wedge seat 305 is provided between the bottom of the air compressor support cylinder 303 and the flip plate 2, and the air compressor support cylinder 303 is located on the wedge surface of the wedge seat 305.

[0046] The piston rod end of the pneumatic support cylinder 303 abuts against any step of the part.

[0047] The tooling 3 on both sides of the flip plate 2 is arranged exactly the same.

[0048] The tooling 3, arranged on one side of the flip plate 2, is arranged in pairs in an alternating manner.

[0049] When the part is clamped, the bottom surface of the part is parallel to the thickness surface of the flip plate 2.

[0050] The flip plate 2 flips 180° in a single rotation.

[0051] The flip plate 2 includes a flip end 202 and a driven end 201. The flip end 202 is connected to the power source in the support base 1.

[0052] The flip plate 2 is used for single-sided tooling 3 for synchronous clamping.

[0053] The specific structure and working principle of this application are as follows:

[0054] like Figures 1-2 As shown, the structure provided in this application is an assembly of multiple tooling sets 3 based on a single flip plate 2. Support seats 1 are provided at both ends of the flip plate 2, and each support seat 1 contains a built-in power source, which can be a motor or a hand-cranked gear pair, to provide the flip plate 2 with the power to flip. The flip plate 2 flips 180° at a time, and each flip moves one of the tooling sets 3 on one side to a horizontal position, where they are processed by external cutting tools or other machining structures.

[0055] like Figure 3 and Figure 4 As shown in this application, tooling 3 is provided on both sides of the flip plate 2. Figure 4 Let's take tooling 3 as an example for explanation.

[0056] Figure 4 The object held by tool 3 in the middle is... Figure 8 , Figure 9 The part to be processed shown has a through hole and a wall composed of multiple arc surfaces. When clamped, one of the through holes faces away from the flip plate 2, and the bottom of the part to be processed is perpendicular to the flip plate 2, and the bottom surface is parallel to the side wall of the flip plate 2.

[0057] Reference Figure 4 and Figure 5 A set of tooling 3 includes a pressurizing cylinder and a pneumatic support cylinder 303. The part to be processed is placed on the positioning seat 301 for holding the part, in conjunction with the reference. Figure 6 , Figure 7 As can be seen, multiple protrusions are also provided on the positioning seat 301. These protrusions are embedded in the through holes of the part to be processed for limiting. At this time, one of the large through holes of the part to be processed is vertically upward.

[0058] An extension arm 306 is connected to the piston rod of the pressurizing cylinder. The extension arm 306 is parallel to the flipping plate 2, and the end of the extension arm 306 facing the workpiece to be processed is provided with a pressurizing plug 307. The pressurizing cylinder drives the extension arm 306 and the pressurizing plug 307 to press down, which presses on the through hole or falls into the through hole, thereby restricting the degree of freedom of the workpiece to be processed perpendicular to the flipping plate 2.

[0059] The pneumatic support cylinder 303 applies a limiting force to the workpiece from the side. The pneumatic support cylinder 303 extends at an angle and abuts against the workpiece. Figure 4 At the circular stepped surface of the part to be processed, all six degrees of freedom of the part are restricted, achieving complete zoning.

[0060] Since all the pressurizing cylinders on one side of the flipping plate 2 in this application are linked, after the part to be processed is placed on the positioning seat 301, all the pressurizing cylinders press down simultaneously to limit the part; the pneumatic support cylinder 303 can extend backward or extend simultaneously with the pressurizing cylinders. After one side of the fixture 3 is clamped, the flipping plate 2 rotates 180° to clamp the other side of the fixture 3. During processing, the part on one side is processed first, and then the part on the other side is processed after flipping.

[0061] This application can be used for machining with both sides clamped together, or for machining with one side clamped and then switching to the other side for machining. It has multiple application modes and a wide range of applications, effectively improving the processing efficiency of mass production.

[0062] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
