Description

Technical Field

[0001] The utility model relates to the technical field of heat sink production equipment, in particular to a retracting knife holder structure. Background Art

[0002] There are some obvious problems in the structural design of the retracting knife holder on the market. Usually, this kind of knife holder adopts a huge aluminum part, which not only requires a long processing time for milling, but also has a high processing difficulty. The inconsistency at this stage directly affects the subsequent assembly process, which requires highly professional operators to perform precise assembly during assembly, increasing the difficulty and complexity of the overall assembly.

[0003] The more serious problem lies in the subsequent debugging and disassembly stage. Due to the use of a single large aluminum part, the debugging and disassembly work becomes quite cumbersome. This not only increases the burden on operators, but also leads to a significant decrease in the qualified rate of products and an upward trend in the scrap rate. This situation not only wastes a lot of valuable materials, but also consumes a lot of time resources.

[0004] This unsmooth design and manufacturing process directly caused great trouble to production operators and commissioning personnel. The production team felt great hardship when facing complex assembly and difficult commissioning. Therefore, in order to improve product quality, reduce scrap rate and improve overall production efficiency, it is urgent to optimize and reasonably design the structure of the retracting knife holder. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a retractable knife holder structure to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0007] A retracting knife holder structure includes a base, which is fixed on a wing machine body. A gantry structure is arranged on the base, and the gantry structure is connected in series with a lower shaft mounting block, an upper shaft mounting block, and an upper cover from bottom to top by a guide rod, and the guide rod is detachably connected to the base.

[0008] It can be seen from the above scheme that the gantry structure arranged on the base has a stable structure, and the detachable connection reduces the burden of component debugging and disassembly, thereby improving work efficiency.

[0009] Furthermore, a lower limit block is installed between the base and the lower shaft mounting block. From the above scheme, it can be seen that the existence of the lower limit block can make the position of the lower shaft mounting block adjustable according to work requirements, and can also play a role in fixing the position of the lower knife shaft in the lower shaft mounting block.

[0010] Furthermore, there are slots at the center of the long end side surfaces of the top and bottom of the lower shaft mounting block.

[0011] Furthermore, an intermediate limiting block is installed between the upper shaft mounting block and the lower shaft mounting block.

[0012] It can be seen from the above technical solution that the existence of the middle limit block can, on the one hand, connect the upper and lower shaft mounting blocks through the slot, and on the other hand, stabilize the working position of the upper tool shaft and make flexible adjustments according to work needs.

[0013] Furthermore, a slot is provided at the center of the long end side surface of the bottom of the upper shaft mounting block.

[0014] Furthermore, the middle limit block is respectively connected to the slot at the bottom end of the upper shaft mounting block and the slot at the top end of the lower shaft mounting block, and the lower limit block is connected to the slot at the bottom of the lower shaft mounting block.

[0015] Furthermore, a circular hole is opened in the center of the upper shaft mounting block, and the upper cutter shaft passes through the circular hole.

[0016] Furthermore, a circular hole is opened in the center of the lower shaft mounting block, and the lower knife shaft passes through the circular hole.

[0017] Furthermore, the guide rods are connected in a bilaterally symmetrical dual-path through-connection manner.

[0018] Furthermore, two pairs of screw holes are evenly arranged along the short side edges on the upper surface of the upper cover, which are threadedly connected to the guide rods and penetrate into the base.

[0019] The utility model has the following beneficial effects:

[0020] 1. The gantry structure adopted by the utility model is more stable than the previous single cantilever structure, and production and debugging are more convenient.

[0021] 2. The utility model adopts a split connection, which reduces the production cost and processing cost required for the replacement of damaged parts. The new structure has a low processing cost and greatly improves the qualified rate of debugging, saving materials, manpower and operator time.

[0022] 3. The existence of the middle limit block and the lower limit block can ensure that the position of the retracting knife and the knife-loading shaft is fixed, and it is not easy to move during work. In addition, the working height can be fine-tuned through the limit block to meet actual use needs. BRIEF DESCRIPTION OF THE DRAWINGS
