Problems solved by technology

In the process of actual workpiece processing, due to various reasons such as force and processing heat of the workpiece, the partial position of the workpiece will float slightly upward, and the supporting column of the auxiliary support is locked and cannot move, resulting in a gap between the supporting column and the workpiece, resulting in Auxiliary support failure
[0003] Springs are used to move the support column for automatic adjustment support, and the rigidity of the structure system is not ideal for locking the ejector pin. The contact area between the slope of the support column and the slope of the ejector pin is small, and the bearing capacity is small. The support is supported under the action of clamping force and cutting force. The column may give way, causing the positioning position to drop

Embodiment Construction

[0038] Below in conjunction with embodiment, the present invention is further described, but does not constitute any restriction to the present invention, anyone makes the limited number of amendments in the scope of claims of the present invention, still within the scope of claims of the present invention.

[0039] The specific embodiment of the present invention is like this: with reference to Figure 1-Figure 20 As shown, a double spring clamp auxiliary support device includes a hollow support seat 1, and a support column 2 for supporting the workpiece is installed in the support seat 1, which can slide up and down. The first wedge 3 of the column 2, the first wedge 3 has an upper wedge surface and a lower wedge surface parallel to each other, and the support column 2 is provided with a lifting mechanism that slides relative to the upper wedge surface of the first wedge 3 and rises. A descending mechanism that slides relative to the lower wedge surface of the first wedge 3 ...

Abstract

The invention discloses a double-spring clamp auxiliary supporting device. The double-spring clamp auxiliary supporting device comprises a hollow supporting seat. A supporting column used for supporting workpieces is installed inside the supporting seat in an up-down sliding mode. A first wedge block penetrating through the supporting column is installed inside the supporting seat in a transverse sliding mode. The first wedge block is provided with an upper wedge surface and a lower wedge surface which are parallel to each other. The supporting column is provided with an ascending mechanism and a descending mechanism, wherein the ascending mechanism slides relative to the upper wedge surface of the first wedge block to ascend, and the descending mechanism slides relative to the lower wedge surface of the first wedge block to descend. A spring compression mechanism capable of automatically pushing the first wedge block to slide and making the supporting column ascend is arranged at one end of the first wedge block. A push rod mechanism capable of pushing the first wedge block to slide and making the supporting column descend is arranged at the other end of the first wedge block. The double-spring clamp auxiliary supporting device is reasonable in structure, auxiliary supporting of the workpieces can be realized, the device can automatically follow the workpieces to move upwards when the workpieces float up so that the workpieces can be supported, clearances are removed, and therefore supporting reliability is guaranteed.

Description

technical field [0001] The invention relates to the field of machining, and more specifically, it relates to an auxiliary supporting device of double spring clamps. Background technique [0002] Machine tool fixtures are used to fix workpieces in the machining process of machinery manufacturing industry. The workpiece needs to be positioned and supported in the fixture. The auxiliary support outside the fixed positioning can effectively improve the overall positioning stiffness, stability and reliability. Every time the workpiece is clamped, the height of the auxiliary support point needs to be readjusted. Auxiliary support of the fixture The automatic adjustment support is a common structure of the fixture. The self-adjusting support contacts the workpiece through the spring jacking up the support column, and the push pin is pushed by the lateral screw rotation, and the slope on the lift pin presses the slope on the support column to lock the support column, that is, the l...
