Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a novel CNC machining fixture for a heat sink fixing housing of an energy storage LED lamp. Background Technology

[0002] Heat sinks are typically designed as thin sheet structures (the thickness may be less than 1 mm), which have poor rigidity. During CNC machining, due to the high speed of the machine tool spindle, the cutting tool is prone to deformation when it is subjected to force with the heat sink being machined. Based on this, this utility model proposes a novel CNC machining fixture for the heat sink of an energy storage LED lamp fixing housing. Utility Model Content

[0003] The purpose of this invention is to provide a novel CNC machining fixture for the heat sink of an energy storage LED lamp mounting housing, thereby solving the aforementioned problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a novel CNC machining fixture for a heat sink mounting housing of an energy storage LED lamp. It includes a base, on which several contoured plastic steel fixing blocks are symmetrically arranged. Each contoured plastic steel fixing block includes a fixing block body, on which several contoured grooves matching the heat sink fins are equidistantly opened. The ribs of the heat sink fins are inserted into the contoured grooves. A reference limiting mechanism and a reference fixing mechanism are symmetrically distributed on the left and right sides of the base. Upper and lower fixing mechanisms for the heat sink fins are symmetrically arranged on the front and rear sides of the reference limiting mechanism / reference fixing mechanism.

[0006] Furthermore, the reference limiting mechanism includes a plastic steel reference limiting block abutting against the outer wall of the product heat sink, and a blade setting reference block is provided on the side of the plastic steel reference limiting block away from the product heat sink.

[0007] Furthermore, the reference fixing mechanism includes a plastic steel pushing and fixing block abutting against the outer wall of the product heat sink, and a cylinder is provided on the side of the plastic steel pushing and fixing block away from the product heat sink.

[0008] Furthermore, the upper and lower fixing mechanism includes an auxiliary cylinder, and the telescopic end of the auxiliary cylinder is provided with a plastic steel pressure block, which presses the heat sink of the product.

[0009] Furthermore, the number of the plurality of the conformal plastic steel fixing blocks is at least three, respectively located at the left and right ends and the center of the product heat sink, and the outer side wall of the conformal plastic steel fixing block located at the left and right ends of the product heat sink is flush with the outer side wall of the product heat sink.

[0010] Furthermore, after the product's heat sink is inserted into the contoured plastic steel fixing block, its upper end face is flush with the upper end face of the contoured plastic steel fixing block.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This utility model relates to a new type of CNC machining fixture for a fixed housing heat sink of an energy storage LED lamp. The fixture places the product on a contoured plastic steel fixing block for clamping, ensuring that the end face of the heat sink is flush with the contoured plastic steel reference block. The fixture also uses a reference limiting mechanism, a reference fixing mechanism, and an upper and lower fixing mechanism to ensure that the heat sink does not wobble on the left and right sides and is locked up and down. This ensures that the heat sink does not deform under stress during processing, and also increases production efficiency and meets processing requirements. Attached Figure Description

Detailed Implementation

[0017] like Figure 1 , 2 As shown, a novel CNC machining fixture for a heat sink mounting housing of an energy storage LED lamp includes a base 1. A plurality of contoured plastic steel fixing blocks 2 are symmetrically mounted on the upper end of the base 1. Each contoured plastic steel fixing block 2 includes a fixing block body 201. A plurality of contoured grooves 202, matching the heat sink 9 of the product, are equidistantly formed on the fixing block body 201. The ribs of the heat sink 9 are inserted into the contoured grooves 202. The number of the contoured plastic steel fixing blocks 2 is at least three; in this embodiment, there are four, located at the left, right, and center positions of the heat sink 9, respectively. The outer walls of the contoured plastic steel fixing blocks 2 located at the left and right ends of the heat sink 9 are flush with the outer walls of the heat sink 9. After the heat sink 9 is inserted into the contoured plastic steel fixing blocks 2, its upper surface is flush with the upper surface of the contoured plastic steel fixing blocks 2.

[0018] The base 1 has a reference limiting mechanism and a reference fixing mechanism symmetrically distributed on its left and right sides, and the product heat sink fixing mechanism is symmetrically installed on the front and rear sides of the reference limiting mechanism / reference fixing mechanism.

[0019] The reference limiting mechanism includes a plastic steel reference limiting block 4 abutting against the outer wall of the product heat sink 9, and a tool setting reference block 3 is installed on the side of the plastic steel reference limiting block 4 away from the product heat sink 9. The reference fixing mechanism includes a plastic steel pushing fixing block 6 abutting against the outer wall of the product heat sink 9, and a cylinder 5 is installed on the side of the plastic steel pushing fixing block 6 away from the product heat sink 9. After the product heat sink 9 is placed on the fixture, the plastic steel reference limiting block 4 is pressed against one side of the product heat sink 9 by the tool setting reference block 3. Then, by activating the cylinder 5, the plastic steel pushing fixing block 6 is pushed against the other side of the product heat sink 9, thereby fixing the left and right sides of the product heat sink 9 and preventing it from shaking in the left and right direction.

[0020] The upper and lower fixing mechanism includes an auxiliary cylinder 7, and a plastic steel pressure block 8 is installed on the telescopic end of the auxiliary cylinder 7. The plastic steel pressure block 8 presses the heat sink 9 of the product. By activating the auxiliary cylinder 7, the plastic steel pressure block 8 at the telescopic end presses against the upper surface of the heat sink 9 of the product, locking the heat sink 9 of the product in place.

[0021] The operation process of this utility model is as follows:

[0022] First, the conformal plastic steel fixing block 2 is bolted onto the base 1 according to the requirements and the size of the product heat sink 9. Then, the plastic steel reference limiting block 4 is pressed against the left side of the product heat sink 9 by the tool setting reference block 3, so that the conformal plastic steel fixing block 2 on the left side and the left side wall of the product heat sink 9 are aligned. After that, the plastic steel pushing fixing block 6 is pushed against the right side of the product heat sink 9 by the starting cylinder 5, so that the conformal plastic steel fixing block 2 on the right side and the right side wall of the product heat sink 9 are aligned. Finally, the auxiliary cylinder 7 is started, and the plastic steel pressure block 8 at the extension end of the auxiliary cylinder 7 is pressed against the upper surface of the product heat sink 9, so that the conformal plastic steel fixing block 2 and the upper surface of the product heat sink 9 are aligned, thus completing the clamping operation of the product heat sink.

[0023] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
