Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and in particular to an auxiliary positioning tooling for a combined intake manifold. Background Technology

[0002] Existing auxiliary positioning fixtures for intake manifolds are mainly used for auxiliary positioning of intake manifolds. However, when in use, the clamps on the existing devices are of fixed specifications. The fixed specifications of the clamps cannot be adapted to intake manifolds of different diameters, which results in a weak clamping effect.

[0003] For example, a Chinese patent discloses an "intake manifold assembly auxiliary tooling" with application number "201520443354.3". In this tooling, the first positioning component and the second positioning component are connected through a main board and can move synchronously. Since the positions of the first positioning component and the second positioning component correspond to the intake manifold assembly holes, during assembly, the first positioning component and the second positioning component are respectively aligned with the assembly holes of the intake manifold and the cylinder head to achieve the positioning of the intake manifold. This can conveniently position the intake manifold that needs to be assembled, reduce the cumbersomeness of loading and unloading, and reduce the labor intensity of workers. However, in its use, it cannot clamp intake manifolds of different specifications, which increases the cost of changing fixtures. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an auxiliary positioning fixture for a combined intake manifold. After the intake manifold falls onto the worktable, the sliding block two is moved by the bidirectional lead screw to control the sliding block three, thereby controlling the opening and closing of the clamping plate. Then, the position of the clamping plate is fixed by the pin, and the intake manifold is clamped forward by the hydraulic push rods on both sides to complete the auxiliary positioning. The opening and closing degree of the clamping plate can be controlled to accommodate intake manifolds of different diameters, avoiding the cost of frequently changing the fixture due to different sizes of intake manifolds, and ensuring the stability of the workpiece position during processing or assembly.

[0005] This utility model also provides an auxiliary positioning fixture with the above-mentioned combined intake manifold, comprising: a base plate, a worktable fixedly connected to the upper surface of the base plate, two slide grooves provided on the worktable, two sliders slidably connected to the inner surfaces of the two slide grooves, a bracket 2 fixedly connected to the upper surface of the base plate, a bidirectional lead screw rotatably connected to the inner surface of the bracket 2, the bidirectional lead screw being threadedly connected to the sliders 2, a connecting rod fixedly connected to the upper surface of the two sliders 2, a slider 3 movably connected to the upper surface of the sliders 2, a through groove provided on the slider 3, the connecting rod being movably connected inside the through groove, clamping plates fixedly connected to the side surfaces of the two pairs of sliders 3, a bracket 1 fixedly connected to the upper surface of the base plate, a hydraulic push rod fixedly connected to the inner surface of the bracket 1, a slide rail fixedly connected to the other end of the hydraulic push rod, sliders 1 fixedly connected to the upper surface of the sliders 3, two sliders 1 slidably connected to the inner surface of the slide rail, each slider 1 and the slide rail having an insertion hole, a pin threadedly connected to the inner wall of each insertion hole, and a pressing plate fixedly connected to the upper surface of each pin.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model discloses an auxiliary positioning fixture for a combined intake manifold, comprising: a base plate 4, a support leg 5 fixedly connected to the lower surface of the base plate 4, a bracket 20 fixedly connected to the lower surface of the support leg 5, a rotating shaft 16 penetratingly connected to the inner surface of the bracket 20, a roller 19 rotatably connected to the rotating shaft 16, a worktable 10 fixedly connected to the upper surface of the base plate 4, two sliding grooves 18 provided on the worktable 10, two sliders 8 slidably connected to the inner surface of each of the two sliding grooves 18, a sliding rod 24 fixedly connected to the inner surface of the bracket 20, the sliders 8 slidably connected to the outer wall of the sliding rod 24, a bracket 20 fixedly connected to the upper surface of the base plate 4, a motor 6 fixedly connected to the outer surface of the bracket 20, and a bidirectional lead screw 12 rotatably connected to the inner surface of the bracket 20, the bidirectional lead screw 12 being driven by the motor 6.

[0023] Specifically: When the intake manifold falls onto the upper surface of the worktable 10, the motor 6 on the bracket 2 7 will drive the bidirectional lead screw 12 to move, and then the bidirectional lead screw 12 will drive the slider 2 8 to move to both sides. The slider 2 8 is internally connected to a slide rod 24, which ensures that the slider 2 8 can slide smoothly and will not be driven to rotate.

[0024] The bidirectional lead screw 12 is threadedly connected to the second slider 8. The upper surfaces of the two second sliders 8 are fixedly connected to the connecting rods 15. The upper surfaces of the second sliders 8 are movably connected to the third slider 17. The third slider 17 is provided with a through groove 21. The connecting rods 15 are movably connected inside the through groove 21. The side surfaces of the two pairs of third sliders 17 are fixedly connected to the clamping plates 9. The two clamping plates 9 are symmetrically arranged and are slidably connected to the upper surface of the worktable 10.

[0025] Specifically: when slider 2 8 moves to both sides, it drives connecting rod 15, which in turn drives slider 3 17, which in turn drives clamping plate 9 to move to both sides. Clamping plate 9 stops when it reaches the size of the intake manifold diameter. Clamping plate 9 is equipped with a rubber soft plate, which can better fix the intake manifold. Clamping plate 9 only moves on the upper surface of worktable 10.

[0026] A bracket 2 is fixedly connected to the upper surface of the base plate 4. A hydraulic cylinder 1 is fixedly connected to the outer surface of the bracket 2. The hydraulic push rod 14 is driven by the hydraulic cylinder 1. The hydraulic push rod 14 is fixedly connected to the inner surface of the bracket 2. The other end of the hydraulic push rod 14 is fixedly connected to the slide rail 3. A slider 13 is fixedly connected to the upper surface of the slider 17. Both sliders 13 are slidably connected to the inner surface of the slide rail 3. Both sliders 13 and slide rail 3 are provided with insertion holes 22. The inner wall of the insertion hole 22 is threaded with a pin 11. The upper surface of the pin 11 is fixedly connected to an extrusion plate 23.

[0027] Specifically: Slider 3 17 drives slider 13 to move on the inner surface of slide rail 3. The pin 11 is manually rotated into the insertion hole until the extrusion plate is attached to the top of slide rail 3. The position of slider 1 is fixed by the friction of the extrusion plate. After the clamping plate 9 is fixed, the hydraulic cylinder 1 drives the hydraulic push rod 14 to push the slide rail 3 and the clamping plate 9 to move towards the middle of the worktable 10, thereby clamping the intake manifold.

[0028] Working principle: When in use, the intake manifold falls onto the worktable 10. The start motor 6 drives the two-way lead screw 12 to control the second slider 8 to move to both sides. When the second slider 8 moves to both sides, it drives the third slider 17 to move to both sides through the connecting rod 15. When the third slider 17 moves, it drives the clamping plate 9 to move, controlling the degree of opening and closing of the clamping plate to make adjustments for different models of intake manifolds.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
