Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a support seat for machining. Background Art

[0002] In machining manufacturing, stable support and clamping of products is one of the important factors to ensure machining accuracy. The traditional support seat used for positioning support is usually a seat body, and a support part for support is integrated on the top of the seat body. This support seat structure is fixed and cannot be adjusted. Therefore, for the processing of products with offset center of gravity (such as the valve plate assembly of an automobile), the above-mentioned traditional structure of the support seat is used for positioning support. The problem of product tilting occurs frequently and is difficult to level, resulting in problems with the positioning reference after clamping, thereby affecting the machining accuracy of the product. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a machining support seat which has a simple structure and can be used to balance the center of gravity of a product.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A support seat for machining, comprising a seat body and a support rod, the support rod comprising a supporting portion and a limiting portion coaxially arranged in sequence from top to bottom, the outer diameter of the limiting portion being larger than the outer diameter of the supporting portion, a cavity cooperating with the limiting portion being arranged in the seat body, an extension hole communicating with the cavity for the upper end of the supporting portion to extend and install being provided at the top of the seat body, the inner diameter of the extension hole being smaller than the outer diameter of the limiting portion, the limiting portion being movably arranged up and down in the cavity, the upper end of the supporting portion extending upward through the extension hole being arranged on the outside of the seat body, an elastic support member being provided at the lower part of the support rod, and the elastic support member being arranged in the cavity.

[0006] The elastic support member is a spring, and the upper end of the spring is arranged against the lower end surface of the limit portion. The elastic support member is a spring, which has a simple structure and stable elastic support.

[0007] The lower end surface of the limit portion is provided with a positioning portion protruding downward, and the upper end of the spring is sleeved on the positioning portion. The positioning portion realizes the positioning and installation of the spring on the support rod, preventing the spring from slipping in the cavity and affecting the elastic support.

[0008] The bottom of the cavity is open, which is convenient for installing the spring and the support rod. When in use, the seat body is installed on the corresponding tooling bottom plate, and the bottom of the cavity is closed by the tooling bottom plate.

[0009] The top of the support portion is provided with a chamfer, which can prevent the support rod from being slightly tilted to support the product without causing damage.

[0010] The bottom end surface of the seat body is recessed upward and provided with an air groove with an outer opening, and the air groove is connected to the cavity. After the seat body is mounted on the tooling base plate, the air groove can effectively prevent a certain pressure in the cavity from affecting and hindering the movement of the support rod.

[0011] The bottom end surface of the seat body is provided with a plurality of air grooves at intervals, so as to facilitate faster exhaust.

[0012] The seat body is provided with a mounting hole which passes through from top to bottom and is used for connection and installation with the tooling base plate.

[0013] Compared with the prior art, the advantages of the present invention are: simple structure, and the support seat composed of the seat body, support rod and elastic support member can realize that the support position of the support rod used to support the relevant parts of the product can have a certain elastic floating. When supporting eccentric products, the support seat of this structure is used in conjunction with the traditional fixed support seat. The support seat of this structure is used to balance the center of gravity of the product, thereby effectively solving the problem of product support tilt, ensuring the support positioning accuracy of the product, and then ensuring the processing and manufacturing accuracy of the product.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0019] As shown in the figure, a support seat for machining includes a seat body 1 and a support rod 2. The support rod 2 includes a support portion 21 and a limiting portion 22 coaxially arranged from top to bottom. The outer diameter of the limiting portion 22 is larger than the outer diameter of the support portion 21. A cavity 11 cooperating with the limiting portion 22 is provided in the seat body 1. The top of the seat body 1 is provided with an extension hole 12 connected to the cavity 11 for the upper end of the support portion 21 to extend and install. The inner diameter of the extension hole 12 is smaller than the outer diameter of the limiting portion 22. The limiting portion 22 can be movably arranged in the cavity 11 up and down. The upper end of the support portion 21 extends upward through the extension hole 12 and is arranged outside the seat body 1. The lower part of the support rod 2 is provided with an elastic support member 3, and the elastic support member 3 is arranged in the cavity 11.

[0020] In this specific embodiment, the elastic support member 3 is a spring, and the upper end of the spring is abutted against the lower end surface of the limiting portion 22. The elastic support member 3 is a spring, which has a simple structure and stable elastic support.

[0021] In this specific embodiment, in order to prevent the spring from slipping in position within the cavity 11 and affecting the elastic support, a downwardly protruding positioning portion 23 is provided on the lower end surface of the limiting portion 22, and the upper end of the spring is sleeved on the positioning portion 23, and the positioning installation of the spring on the support rod 2 is achieved through the positioning portion 23.

[0022] In this specific embodiment, in order to facilitate the installation of the spring and the support rod 2, the cavity 11 is designed as a cavity with an open bottom. During specific use, the base body 1 is installed on the corresponding tooling base plate 4, and the bottom of the cavity 11 is closed by the tooling base plate 4.

[0023] In this specific embodiment, in order to prevent the sharp corners from damaging the product 5 when the support rod 2 is slightly tilted, a chamfer 211 is provided on the top of the support portion 21 .

[0024] In this specific embodiment, the support rod 2 will squeeze the gas in the cavity 11 during the up and down movement. In order to effectively prevent the certain pressure in the cavity 11 from affecting and hindering the movement of the support rod 2, an air groove 13 with an outer opening is provided on the bottom end surface of the base body 1. The air groove 13 is connected to the cavity 11, and the squeezed air in the cavity 11 is discharged outward through the air groove 13.

[0025] In this specific embodiment, in order to achieve faster exhaust, a plurality of air grooves 13 are provided at intervals on the bottom end surface of the seat body 1 .

[0026] In this embodiment, the base body 1 is provided with a mounting hole 14 extending vertically therethrough, which is used to connect and mount to the tooling base plate 4 .
