Description

Technical Field

[0001] The utility model relates to the technical field of precision machining of micro-sized cylindrical thin-wall products, in particular to a 4-axis / 5-axis tooling for micro-sized cylindrical thin-wall products. Background Art

[0002] In the prior art, when clamping and fixing miniature cylindrical thin-walled products, tooling is usually used to clamp the miniature cylindrical thin-walled products from the outside of the product. However, since the outer wall of the product is relatively thin, during the actual clamping process, the product is easily deformed due to excessive clamping force, thereby increasing the product defective rate.

[0003] In addition, since the product is cylindrical, it is difficult to clamp it from the outside. After clamping, the product is easy to move, which affects the clamping and positioning accuracy.

[0004] Therefore, it is necessary to invent a 4-axis / 5-axis micro-cylindrical thin-walled product tooling to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a 4-axis / 5-axis miniature cylindrical thin-walled product tooling, which is provided with an inner clamping mechanism so that after the product to be clamped is inserted into the inner side of the positioning tube from the opening at the left end of the positioning tube, the left end of the clamping pin enters the inner side of the product, and then the first hexagonal socket bolt is rotated with a hexagonal wrench. After the first hexagonal socket bolt is rotated, it descends inside the third screw hole, and then the pin rod of the clamping pin is pressed down. At this time, the pin rod of the clamping pin is tilted under pressure, and the left end of the pin rod is pressed against the inner wall of the product, thereby cooperating with the positioning tube to complete the clamping of the product. In order to solve the problem raised in the above background technology that in the prior art, the tooling for clamping and fixing micro-sized cylindrical thin-walled products usually adopts the method of clamping from the outside of the product when clamping the micro-sized cylindrical thin-walled products. However, due to the thin outer wall of the product, the product is easily deformed due to excessive clamping force during the actual clamping process, thereby increasing the product defective rate. In addition, due to the cylindrical shape of the product, it is difficult to clamp it when clamping it from the outside, and the product is easy to move after clamping, thereby affecting the clamping and positioning accuracy.

[0007] A carrying mechanism, the carrying mechanism is used to install the external positioning mechanism and the internal clamping mechanism and is clamped by a 4-axis / 5-axis three-jaw chuck;

[0016] The positioning tube is slidably arranged inside the mounting hole, and the fixing ring is fixedly arranged at the left end outside the fixing ring.

[0017] According to at least one embodiment of the 4-axis / 5-axis miniature cylindrical thin-wall product tooling disclosed herein, the external positioning mechanism further includes a second screw hole and a mounting bolt;

[0018] The second screw hole is opened at the left end of the carrying rod, and the mounting bolt slides through the fixing ring and is threadedly connected to the inner side of the second screw hole.

[0019] Technical effects and advantages of the utility model:

[0020] The utility model is provided with an internal clamping mechanism, so that after the product to be clamped is inserted into the inner side of the positioning tube through the opening at the left end of the positioning tube, the left end of the clamping pin enters the inner side of the product, and then the hexagonal wrench is used to rotate the first hexagonal bolt.

[0030] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "above," "on," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would then be positioned "above" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0032] Figure 2 It is a structural schematic diagram of an external positioning mechanism 2 of a 4-axis / 5-axis miniature cylindrical thin-walled product tooling according to an embodiment of the present disclosure.

[0033] Figure 3 It is a schematic structural diagram of a loading mechanism 1 and an inner clamping mechanism 3 of a 4-axis / 5-axis miniature cylindrical thin-walled product tooling according to an embodiment of the present disclosure.

[0034] like Figure 1-Figure 3 As shown, the 4-axis / 5-axis micro-miniature cylindrical thin-walled product tooling disclosed herein may include: a mounting mechanism 1, an external positioning mechanism 2, an internal clamping mechanism 3, and a micro-miniature cylindrical thin-walled product 4 and other components.

[0035] like Figure 3 As shown, in the present disclosure, the carrying mechanism 1 includes a carrying rod 11, a first screw hole 12 and a mounting hole 13, wherein the first screw hole 12 is opened at the right end of the carrying rod 11, and the mounting hole 13 is opened at the left end of the carrying rod 11, and the first screw hole 12 and the mounting hole 13 are coaxially arranged and connected to each other.

[0036] Therefore, after the clamping pin 33 is inserted into the inner side of the mounting hole 13 through the first screw hole 12, the second hexagon socket bolt 34 is screwed into the inner side of the first screw hole 12, so that the second hexagon socket bolt 34 presses the clamping pin 33 to prevent it from moving freely.

[0037] like Figure 2As shown, in a preferred embodiment, the external positioning mechanism 2 includes a second screw hole 21, a positioning tube 22, a fixing ring 23 and a mounting bolt 24, wherein the second screw hole 21 is opened at the left end of the carrying rod 11, the positioning tube 22 is slidably arranged on the inner side of the mounting hole 13, the fixing ring 23 is fixedly arranged on the outer left end of the fixing ring 23, and the mounting bolt 24 slides through the fixing ring 23 and is threadedly connected to the inner side of the second screw hole 21.

[0038] Therefore, when the outer diameter of the product changes, the mounting bolt 24 is unscrewed from the inside of the second screw hole 21, and then the positioning tube 22 is driven out from the inside of the mounting hole 13 through the fixing ring 23, and then a new positioning tube 22 that meets the product specifications is replaced and inserted into the inside of the mounting hole 13, and then the mounting bolt 24 is tightened to complete the replacement of positioning tubes 22 of different specifications.

[0040] In this way, after the product to be clamped is inserted into the inner side of the positioning tube 22 through the opening at the left end of the positioning tube 22, the left end of the clamping pin 33 enters the inner side of the product, and then the first hexagon socket bolt 32 is rotated using a hexagonal wrench. After the first hexagon socket bolt 32 is rotated, it descends inside the third screw hole 31, and then the pin rod of the clamping pin 33 is pressed down. At this time, the pin rod of the clamping pin 33 is tilted due to pressure, and the left end of the pin rod is pressed against the inner wall of the product, and then the positioning tube 22 is cooperated to complete the clamping of the product, and then the carrying rod 11 is placed in the 4-axis / 5-axis three-jaw chuck for clamping, and the product can be processed.
