Technical Field

[0001] The invention relates to the technical field of product machining, and in particular to an auxiliary supporting mechanism for machining. Background Art

[0002] At present, in the process of using machining fixtures, for products with complex structures and high machining accuracy, the problem of tool chattering in the hole frequently occurs. Therefore, it is necessary to provide an auxiliary support mechanism on the side of the product after the product is positioned and clamped. The conventional auxiliary support mechanisms are all fixed hard supports, and a support cylinder's push rod is often used to directly provide auxiliary support. However, the structural strength of some products (such as automobile valve plates) is relatively weak. Using this traditional support cylinder for auxiliary support can easily deform the product, which is not conducive to the manufacturing quality of the product. Summary of the invention

A limiting convex ring is provided on the connecting rod protruding outward, and the spring is arranged between the bottom end surface of the connecting cavity and the limiting convex ring.

[0007] The second end of the connecting rod has a mounting screw hole, and the supporting slider has a mounting hole for communicating with the connecting cavity. The supporting slider and the connecting rod are fixedly installed by passing the rod of the mounting bolt that matches the mounting screw hole through the mounting hole and being screwed in 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 surface of the connecting cavity can be used to limit the spring.

[0008] A limiting column for limiting the screwing position of the mounting bolt is arranged in the supporting slider, a limiting hole penetrating front to back is arranged in the limiting column, the limiting hole is coaxial with the mounting hole, the rod of the mounting bolt passes through the limiting hole and the mounting hole in sequence and is screwed into the mounting screw hole.

[0009] A support head is detachably mounted on the support sliding block, and the support head has a support portion, and the support portion extends out of the support sliding block.

[0010] A guide cavity which is through-through from front to back and matches with the support sliding block is arranged in the positioning seat, and the support sliding block can be movably arranged in the guide cavity from front to back.

[0011] It also includes a push cylinder seat, and the cylinder body supporting the push cylinder is installed on the push cylinder seat.

[0012] A protective cover is arranged between the push cylinder seat and the positioning seat.

[0013] Compared with the prior art, the advantages of the present invention are: simple structure, when the support push cylinder is pushed into place, the support component can float in a front and rear position through the elastic connection mechanism, forming elastic auxiliary support for the product, thereby avoiding deformation of the product, ensuring the manufacturing quality of the product and reducing the defective rate.

DETAILED DESCRIPTION

[0015] The present invention is further described in detail below with reference to the accompanying drawings.

[0016] As shown in the figure, an auxiliary support mechanism for machining includes a positioning seat 1, on which a support member 2 for auxiliary support of product A is movably arranged forward and backward, and the support member 2 is driven by a support push cylinder 3, and the support push cylinder 3 and the support member 2 are connected by an elastic connection mechanism that allows the support member 2 to float forward and backward after being pushed into place by the support push cylinder 3.

[0017] In this specific embodiment, the elastic connection mechanism includes a connecting rod 4, the first end of the connecting rod 4 is coaxially fixedly connected to the push rod 31 of the support push cylinder 3, the second end of the connecting rod 4 is fixedly connected to the support member 2, and an elastic support member 5 is provided between the connecting rod 4 and the support push cylinder 3. The above elastic connection mechanism has a simple structure, and the support push cylinder 3 drives the support member 2 to move forward and backward through the connecting rod 4. When the support push cylinder 3 is pushed out to the right position, the support member 2 is supported on the product A. Under the action of the elastic support member 5, the support member 2 can float forward and backward to form a support with a certain elastic force, thereby preventing the product A from being deformed by being pushed.

[0018] In this specific embodiment, the support member 2 includes a support slider 201, which can be movably arranged on the positioning seat 1, and the elastic support member 5 is a spring, which is sleeved and installed on the connecting rod 4. A connecting cavity 21 is arranged in the support slider 201, and the second end of the connecting rod 4 is inserted into the connecting cavity 21 and fixedly connected to the support slider 201. A limiting convex ring 41 is protruded outwardly on the connecting rod 4, and the spring is arranged between the bottom end surface 211 of the connecting cavity 21 and the limiting convex ring 41. The front and rear limits are formed for the spring by the connecting cavity 21 and the limiting convex ring 41, thereby providing a stable elastic supporting force for the support member 2.

[0019] In this specific embodiment, the second end of the connecting rod 4 has a mounting screw hole 42, and the supporting slider 201 has a mounting hole 22 for communicating with the connecting cavity 21. The supporting slider 201 and the connecting rod 4 are fixedly installed by passing the rod of the mounting bolt (not shown in the figure) matched with the mounting screw hole 42 through the mounting hole 22 and being screwed in the mounting screw hole 42; the inner diameter of the mounting hole 22 is smaller than the inner diameter of the connecting cavity 21, so that the bottom end surface 211 of the connecting cavity 21 can be used for the limit spring. The structure for realizing the fixed installation of the connecting rod 4 and the supporting slider 201 is simple and easy to install and disassemble.

[0020] In this specific embodiment, a limiting column 6 for limiting the screwing position of the mounting bolt is provided in the support slider 201, and a limiting hole 61 is provided in the limiting column 6, which is through the front and back. The limiting hole 61 is coaxial with the mounting hole 22, and the rod 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 screwing position of the mounting bolt is limited by the limiting column 6 to prevent damage to the connecting rod 4 caused by excessive screwing.

[0021] In this specific embodiment, a support head 202 is detachably mounted on the support slider 201, and the support head 202 has a support portion 23, and the support portion 23 is extended and arranged outside the support slider 201. The product is auxiliary supported by the support portion 23 on the support head 202, and the support head 202 is detachably mounted on the support slider 201. In order to assist in supporting different products, the support head 202 can be replaced to match the auxiliary support of different products, so that the versatility is better.

[0022] In this specific embodiment, a guide cavity 11 is provided in the positioning seat 1 and is connected to the support slider 201. The support slider 201 can be movably arranged in the guide cavity 11. The matching guide cavity 11 is used to guide the forward and backward movement of the support slider 201, limiting the support slider 201 to only float in the forward and backward direction, ensuring that the support head 202 can form a stable auxiliary support for the product.

[0023] 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 of the push cylinder 3 is installed on the push cylinder seat 7, and the push cylinder seat 7 is installed on the tooling bottom plate.

[0024] In this specific embodiment, in order to protect the exposed portion of the support push cylinder 3 , a protective cover 8 is provided between the push cylinder seat 7 and the positioning seat 1 , so that the exposed portion of the support push cylinder 3 is covered by the protective cover 8 .

[0025] The positioning seat 1 and the push cylinder seat 7 are fixedly installed on the corresponding positions of the tooling base plate, and are pushed out by the support push cylinder 3. After being pushed into place, under the action of the spring, the support part 23 of the support head 202 forms an elastic support for the corresponding part of the product A.
