Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically to a clamp for a turntable base rear shock absorber. Background Technology

[0002] A type of turntable base rear shock absorber is a metal die-casting part. After the die-casting is completed, mounting holes need to be machined at predetermined positions on its surface. The turntable base rear shock absorber has a complex shape and structure, and its mounting holes are distributed on multiple surfaces at different angles. Therefore, multiple sets of fixtures need to be designed during machining, and multiple clamping is required to complete the machining. Among them, the fixture manufacturing cost is high, the machining efficiency is low, and the existing fixtures have poor support effect, which can easily cause product deformation during machining. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model provides a rotary table base rear shock absorber machining fixture, which has a simple structure, is easy to clamp, and can reduce fixture costs and improve machining efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rotary table base rear shock absorber clamp is characterized by comprising a base plate, a rotating seat, and a bridge plate. Two rotating seats are arranged opposite each other on the base plate. The bridge plate is disposed between the rotating seats and rotatably connected to them. One of the rotating seats is equipped with a servo mechanism for driving the bridge plate to rotate. Two clamp mounting plates are arranged side-by-side on the bridge plate. Each clamp mounting plate is equipped with two first support seats and one second support seat. The first and second support seats form a positioning surface. The clamp mounting plate is equipped with a front positioning block and a side positioning block. First pressure plates are provided in the direction directly opposite the support surfaces of the first and second support seats.

[0006] Furthermore, the fixture mounting plate is provided with a plurality of mounting supports, and a first floating support is provided on the mounting support. A second pressure plate is provided in the direction directly opposite to the support surface of the first floating support. The second pressure plate is driven by a spinning cylinder, which is located on the mounting support.

[0007] Furthermore, the clamp mounting plate is provided with second floating supports arranged vertically and diagonally.

[0008] Furthermore, the fixture mounting plate is provided with a prepositioning block opposite to the side positioning block, and the upper part of the prepositioning block has a guide slope.

[0009] Furthermore, the first pressure plate is driven by a lever-operated clamping cylinder or a rotary clamping cylinder.

[0010] The beneficial effects of this utility model include: enabling four-axis machining on a conventional machine tool using a single set of fixtures, while reducing the number of fixtures required, improving machining efficiency, and lowering machining costs. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of the clamping state of this utility model. Detailed Implementation

[0013] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0014] One such Figure 1-2 The rotary table base rear shock absorber and fixture shown includes a base plate 1, a rotary seat 2, and a bridge plate 3. There are two rotary seats 2, which are arranged opposite each other on the base plate 1. The bridge plate 3 is arranged between the rotary seats 2 and is rotatably connected to the rotary seats 2. One of the rotary seats 2 is equipped with a servo mechanism 4 that drives the bridge plate 3 to rotate. This structure constitutes a flip axis mechanism. With the servo mechanism 4, it can realize the replacement of four-axis machining on a conventional three-axis machine tool.

[0015] Two clamping mounting plates 5 are arranged side-by-side on the bridge plate 3, allowing for the simultaneous clamping of two sets of clamps. Each clamping mounting plate 5 has two first support seats 6 and one second support seat 7, which together form a positioning surface defined by three points. The clamping mounting plate 5 is equipped with a front positioning block 8 for positioning the front face of the workpiece and a side positioning block 9 for positioning one side of the workpiece, thus achieving complete workpiece positioning. First pressure plates 10 are positioned opposite each other on the support surfaces of the first support seats 6 and 7. The first pressure plates 10 are driven by a lever-operated clamping cylinder or a rotary clamping cylinder, thereby achieving workpiece positioning and clamping.

[0016] To further improve the support stability of the fixture and prevent deformation during processing, this embodiment provides multiple mounting supports 11 on the fixture mounting plate 5. A first floating support 12 is mounted on each mounting support 11, and a second pressure plate 13 is positioned opposite the support surface of the first floating support 12. The second pressure plate 13 is driven by a spinning cylinder 14, which is fixedly mounted on the mounting support 11. Additionally, the fixture mounting plate 5 provides vertically and diagonally arranged second floating supports 15.
