Description

Technical Field

[0001] This utility model relates to the field of production and processing technology, and in particular to a machining suction cup fixture. Background Technology

[0002] Currently, most products are machined using flat-jaw bench vises. However, using a flat-jaw bench vise to hold and fix products means that only one product can be clamped at a time, resulting in low clamping efficiency. Furthermore, manual clamping is required, which makes it difficult to control the clamping force. This can easily cause deformation of thinner products, leading to a large number of defective parts and excessively high manufacturing costs.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a machining chuck fixture. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a machining suction cup fixture to solve the product deformation problem caused by manual clamping of thin workpieces, improve processing efficiency, and reduce the occurrence of defective products.

[0005] To solve the above-mentioned technical problems, the present invention provides a machining suction cup fixture, which includes a fixture body, pins, and a sealing ring. The top surface of the fixture body has two suction cup positions for positioning and adsorbing products, namely a front adsorption position and a back adsorption position. Both the front and back adsorption positions have product placement grooves. At least two pins for positioning products are installed in the front placement groove, and the pins engage with conical holes on the product. The pins are frustoconical in shape. A sealing ring for sealing the center of the product is installed in the front placement groove. The fixture includes a first sealing ring, a second sealing ring for sealing the conical hole of the product, and a third sealing ring for sealing the product. The back dimension of the conical hole is larger than its front dimension. The second sealing rings at two adjacent conical holes are annular sealing rings, which jointly seal the two adjacent conical holes. The second sealing rings are large in size and close to the first sealing ring. Three independent adsorption cavities are provided at the front placement groove. The side end of the fixture body is provided with a first air extraction hole that communicates with the adsorption cavity. The first air extraction hole is connected to a vacuum pump through a plastic air pipe. The operation of the vacuum pump exhausts air outward, thereby generating suction force to firmly hold and fix the product.

[0006] Preferably, the reverse placement groove is provided with an arc-shaped groove for positioning several arc-shaped protrusions on the product. The reverse placement groove is equipped with a fourth sealing ring for sealing the central hole of the product, a fifth sealing ring for sealing the conical hole of the product, and a sixth sealing ring for sealing the product. The fifth sealing ring is far away from the fourth sealing ring. The reverse placement groove is provided with a connected adsorption chamber. A second air extraction hole communicating with the adsorption chamber is opened on the side end of the fixture body. The second air extraction hole is connected to a vacuum pump through a plastic air pipe.

[0007] Preferably, the fixture body is provided with sliding grooves on both sides for easy clamping and fixing, so that the fixture body can be clamped and fixed to the machining equipment.

[0008] Preferably, the fixture body is made of metal.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The shape and structure of the fixture body and the clearance fit of the sealing ring achieve the suction cup condition, meet the product processing needs, clamp two products at a time, improve processing efficiency, solve the product deformation problem caused by manual clamping of thin workpieces, and reduce the occurrence of defective products.

Detailed Implementation

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] Please see Figures 1 to 4 The embodiments of this utility model include:

[0019] A machining chuck fixture includes a fixture body 1, a pin 2, a first sealing ring 3, a second sealing ring 4, a third sealing ring 5, a fourth sealing ring 6, a fifth sealing ring 7, and a sixth sealing ring 8.

[0020] The top surface of the fixture body 1 is provided with two suction cup stations for positioning and adsorbing the product 00. The two suction cup stations are the front adsorption station 11 and the back adsorption station 12.

[0021] The product 00 is a circular, thin metal part. The product 00 has a central hole 01 in the middle and five conical holes 02 surrounding the central hole 01. The conical holes 02 are arranged in pairs. The size of the conical holes 02 increases from the front to the back of the product. The product 00 has several arc-shaped bosses 03 extending upwards from the front.

[0022] A product placement groove is provided at the front adsorption station 11. At least two pins 2 for positioning the product 00 are installed on the placement groove. The pins 2 engage with the conical holes 02 on the product 00. The pins 2 are frustoconical in shape, and the direction of the product 00 is fixed by the frustoconical pins 2. A first sealing ring 3 for sealing the product's center hole 01, a second sealing ring 4 for sealing the product's conical hole 02, and a third sealing ring 5 are installed at the placement groove. Because the back dimensions of adjacent conical holes 02 are large, there is not enough space for a single sealing ring to seal each conical hole. Therefore, the second sealing ring 4 is an annular sealing ring, which works together... The two conical holes 02 are sealed close together. Due to the large size of the back of the conical holes 02, the second sealing ring 4 is correspondingly large. The second sealing ring 4 is close to the first sealing ring 3. Three independent adsorption cavities 110 are set in the placement groove. Due to the tight sealing ring, the three adsorption cavities 110 cannot be opened, otherwise it will affect the installation of the sealing ring and the sealing effect. The side end of the fixture body 1 is respectively provided with a first air extraction hole 111 that communicates with the adsorption cavity 110. The first air extraction hole 111 is connected to a vacuum pump through an 8mm plastic air pipe. The vacuum pump runs to exhaust air outward, thereby generating suction force to firmly hold and fix the product.

[0023] The reverse adsorption station 12 is also provided with a product placement slot. The product placement slot is provided with an arc-shaped groove 120 for positioning several arc-shaped protrusions 03 on the product. The product placement slot is equipped with a fourth sealing ring 6 for sealing the product's central hole 01, a fifth sealing ring 7 for sealing the product's conical hole 02, and a sixth sealing ring 8 for sealing the product. The product placement slot is provided with a connected adsorption chamber 121. The side end of the fixture body 1 is provided with a second air extraction hole 122 that communicates with the adsorption chamber 121. The second air extraction hole 122 is connected to a vacuum pump through an 8mm plastic air pipe. The vacuum pump runs and exhausts air outward, thereby generating suction to firmly hold and fix the product.

[0024] The fixture body 1 is provided with sliding grooves 13 on both sides for easy clamping and fixing. The fixture body 1 can be clamped and fixed to the machining equipment for subsequent product processing.

[0025] The fixture body 1 is made of metal.

[0026] This utility model discloses a machining suction cup fixture. During operation, two products, one facing forward and one facing backward, are placed sequentially on the front suction station 11 and the other on the back suction station 12 of the fixture body 1. The front-facing product is fixed in orientation by a frustum-shaped pin 2, while the back-facing product is positioned by an arc-shaped groove 120. After placement, the first and second air extraction holes are connected to an external vacuum pump via 8mm plastic tubing. The vacuum pump draws air outward, generating suction to firmly hold and fix the product in place. Since both the product and the fixture are metal parts, gaps may appear after the surfaces are joined, causing air leakage. Placing a sealing ring between the fixture body 1 and the product provides excellent sealing. The product is vacuum-adsorbed onto the fixture body, allowing for product processing. This method is highly efficient, eliminates metal indentations, and significantly improves the appearance quality.

[0027] This utility model discloses a machining suction cup fixture. The shape and structure of the fixture body and the gap fit of the sealing ring achieve the suction cup condition, meet the product processing needs, clamp two products at a time, improve processing efficiency, solve the product deformation problem caused by manual clamping of thin workpieces, and reduce the occurrence of defective products.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
