Abstract
Description
Technical Field
[0001] This utility model relates to the field of product machining technology, and in particular to an auxiliary support mechanism for machining. Background Technology
[0002] Currently, in the use of machining fixtures, the problem of internal vibration occurs frequently for products with complex structures and high machining precision. Therefore, after the product is positioned and clamped, an auxiliary support mechanism is needed on the side of the product. The auxiliary support mechanism commonly used is a fixed rigid support, which often uses the push rod of a support cylinder to directly assist in the support. However, for some products (such as automotive valve plates) with relatively weak structural strength, using this traditional support cylinder to assist in the support can easily deform the product, which is not conducive to the manufacturing quality of the product. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a simple structure that can not only provide effective support but also prevent product deformation.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0005] An auxiliary support mechanism for machining includes a positioning seat, on which a support member for auxiliary support of a product is movably disposed. The support member is driven by a support cylinder, and the support cylinder and the support member are connected by an elastic connecting mechanism that allows the support member to float back and forth after the support cylinder is pushed out to its position.
[0006] The elastic connection mechanism includes a connecting rod, the first end of which is coaxially and fixedly connected to the push rod of the support cylinder, the second end of which is fixedly connected to the support member, and an elastic support member is provided between the connecting rod and the support cylinder.
[0007] The supporting component includes a supporting slider, which is movably mounted on the positioning seat. The elastic supporting component is a spring, which is sleeved on the connecting rod. A connecting cavity is provided inside the supporting slider. The second end of the connecting rod extends into the connecting cavity and is fixedly connected to the supporting slider. A limiting protrusion is provided on the connecting rod. The spring is disposed between the bottom end face of the connecting cavity and the limiting protrusion.
[0008] The second end of the connecting rod has a mounting screw hole, and the support slider has a mounting hole for communicating with the connecting cavity. The support slider and the connecting rod are fixedly installed by the rod of the mounting bolt that mates with the mounting screw hole passing through the mounting hole and screwed into the mounting screw hole. The inner diameter of the mounting hole is smaller than the inner diameter of the connecting cavity, so that the bottom end face of the connecting cavity can be used to limit the spring.
[0009] The support slider is provided with a limiting post for limiting the screwing position of the mounting bolt. The limiting post is provided with a limiting hole that runs through the front and back. The limiting hole is coaxial with the mounting hole. The shank of the mounting bolt passes through the limiting hole and the mounting hole in sequence and is screwed into the mounting bolt hole.
[0010] The support slider is detachably mounted with a support head, the support head having a support portion that extends outward from the support slider.
[0011] The positioning seat is provided with a guide cavity that runs through the front and back and cooperates with the support slider. The support slider is movably disposed in the guide cavity.
[0012] It also includes a pusher cylinder seat, on which the cylinder body supporting the pusher cylinder is mounted.
[0013] A protective cover is provided between the pusher seat and the positioning seat.
[0014] Compared with the prior art, the advantages of this utility model are: simple structure; after the support cylinder is pushed out to the position, the support component can float in a front and back position through the elastic connection mechanism, forming an elastic auxiliary support for the product, thereby avoiding deformation of the product, ensuring the manufacturing quality of the product and reducing the defect rate.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0020] As shown in the figure, an auxiliary support mechanism for machining includes a positioning seat 1. A support member 2 for auxiliary support of product A is movably arranged on the positioning seat 1. The support member 2 is driven by a support cylinder 3. The support cylinder 3 and the support member 2 are connected by an elastic connecting mechanism that allows the support member 2 to float back and forth after the support cylinder 3 is pushed out to the position.
[0021] In this specific embodiment, the elastic connection mechanism includes a connecting rod 4. The first end of the connecting rod 4 is coaxially and fixedly connected to the push rod 31 of the support cylinder 3, and the second end of the connecting rod 4 is fixedly connected to the support member 2. An elastic support member 5 is provided between the connecting rod 4 and the support cylinder 3. The above-mentioned elastic connection mechanism has a simple structure. The connecting rod 4 enables the support cylinder 3 to drive the support member 2 to move back and forth. When the support cylinder 3 is pushed out to the correct position, the support member 2 supports the product A. Under the action of the elastic support member 5, the support member 2 can float back and forth, forming a support with a certain elastic force, thereby preventing the product A from being deformed.
[0022] In this specific embodiment, the support member 2 includes a support slider 201, which is movably mounted on the positioning seat 1. The elastic support member 5 is a spring, which is sleeved on the connecting rod 4. A connecting cavity 21 is provided inside the support slider 201. The second end of the connecting rod 4 extends into the connecting cavity 21 and is fixedly connected to the support slider 201. A limiting ring 41 protrudes outward on the connecting rod 4. The spring is disposed between the bottom end face 211 of the connecting cavity 21 and the limiting ring 41. The connecting cavity 21 and the limiting ring 41 form a front limit and a rear limit for the spring, thereby providing a stable elastic support force for the support member 2.
[0023] In this specific embodiment, the second end of the connecting rod 4 has a mounting screw hole 42, and the support slider 201 has a mounting hole 22 for communicating with the connecting cavity 21. The rod of the mounting bolt (not shown in the figure) that mates with the mounting screw hole 42 passes through the mounting hole 22 and is screwed into the mounting screw hole 42 to achieve the fixed installation of the support slider 201 and the connecting rod 4. The inner diameter of the mounting hole 22 is smaller than the inner diameter of the connecting cavity 21, so that the bottom end face 211 of the connecting cavity 21 can be used for the limiting spring. The structure for fixing the connecting rod 4 and the support slider 201 is simple and easy to install and disassemble.
[0024] In this specific embodiment, the support slider 201 is provided with a limiting post 6 for limiting the screwing position of the mounting bolt. The limiting post 6 is provided with a limiting hole 61 that runs through the front and back. The limiting hole 61 is coaxial with the mounting hole 22. The shank of the mounting bolt passes through the limiting hole 61 and the mounting hole 22 in sequence and is screwed into the mounting screw hole 42. The limiting post 6 limits the screwing position of the mounting bolt, avoiding excessive screwing and damage to the connecting rod 4.
[0025] In this specific embodiment, a support head 202 is detachably mounted on the support slider 201. The support head 202 has a support portion 23 that extends outward from the support slider 201. The support portion 23 on the support head 202 provides auxiliary support for the product. The support head 202 is detachably mounted on the support slider 201. By using different support for different products, a suitable support head 202 can be replaced, resulting in better versatility.
[0026] In this specific embodiment, the positioning base 1 is provided with a guide cavity 11 that runs through the front and back and cooperates with the support slider 201. The support slider 201 is movably disposed in the guide cavity 11. The cooperating guide cavity 11 guides the front and back movement of the support slider 201, limiting the support slider 201 to floating movement in the front and back direction, and ensuring that the support head 202 can provide stable auxiliary support for the product.
[0027] In this specific embodiment, in order to achieve stable support installation of the push cylinder 3, a push cylinder seat 7 is also included. The cylinder body 32 supporting the push cylinder 3 is mounted on the push cylinder seat 7, and the push cylinder seat 7 is mounted on the tooling base plate.
[0028] In this specific embodiment, in order to protect the exposed part of the support cylinder 3, a protective cover 8 is provided between the cylinder seat 7 and the positioning seat 1, so that the exposed part of the support cylinder 3 is covered by the protective cover 8.
[0029] Positioning seat 1 and push cylinder seat 7 are fixedly installed on the corresponding positions of the tooling base plate. They are pushed out by the support push cylinder 3. After being pushed out into place, the support part 23 of the support head 202 provides elastic support to the corresponding part of product A under the action of the spring.
