Description

Technical Field

[0001] The utility model belongs to the field of fixture work counting, and more specifically relates to a slot processing tooling. Background Art

[0002] First, it is necessary to process slots on a water pump part with a circular outer side using a milling machine for milling. Due to the requirement for the slot angle, the circular outer side limits the positioning accuracy of the part, making it difficult to achieve very precise positioning and affecting the subsequent assembly quality of the part; parts with the same structure but different sizes may require frequent replacement of the tooling, increasing the complexity of the operation. The installation and disassembly process of the tooling is time-consuming and laborious, and it is not convenient to move and flexibly use according to the change of the part size. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a slot processing tooling, which is more flexible, convenient, time-saving and labor-saving when frequently replacing parts of different sizes.

[0004] To achieve the above object, the utility model provides the following technical solution: A slot processing tooling, including a base, a six-jaw chuck is arranged on the base, a positioning device is arranged between two of the jaws on the six-jaw chuck. The positioning device includes a fixed block, an installation block is arranged on the fixed block, the installation block is detachably connected to the fixed block, a positioning pin shaft is arranged on the installation block, the positioning pin shaft is detachably connected to the installation block, positioning pin heads are arranged at both ends of the positioning pin shaft, and the diameter of the positioning pin head at one end is larger than that at the other end.

[0005] Further, an installation hole is arranged on the installation block, the positioning pin shaft extends into the installation hole, and the positioning pin head passes through the installation hole.

[0006] Further, an installation groove is arranged on the fixed block, a clamping groove is arranged at one end of the installation groove facing the center of the six-jaw chuck, the clamping groove is communicated with the installation groove, the installation block is clamped in the clamping groove, and the positioning pin shaft is located in the installation groove.

[0007] Further, the installation block is an isosceles trapezoidal block, and both sides of the clamping groove are matched with the two base angles of the isosceles trapezoidal block.

[0008] Further, a waist-shaped through groove is arranged on the fixed block, a fixing bolt is arranged between the waist-shaped through groove and the six-jaw chuck, and the fixing bolt passes through the waist-shaped through groove and is threadedly connected to the six-jaw chuck.

[0009] Further, a support block is arranged at one end of the installation groove far from the center of the six-jaw chuck, and an arc-shaped support groove corresponding to the positioning pin shaft is arranged on the support block.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: When processing parts, the parts are first positioned by the positioning pin head and then clamped by the six-jaw chuck, improving the clamping efficiency. Taking the positioning hole on the part as the reference, the processing accuracy of the slot is higher, improving the assembly quality of the parts; when processing parts of different sizes, the positioning pin on the mounting block can be taken out first, the positioning pin head at the other end can be turned around and then the positioning pin is inserted into the mounting hole, or the positioning pin with different sizes of positioning pin heads can be directly replaced, which is more flexible, convenient, time-saving and labor-saving for frequently replacing parts of different sizes.

[0018] Preferably in this embodiment, an installation hole (not shown in the attached drawings) is arranged on the installation block 3, the positioning pin shaft 4 extends into the installation hole, and the positioning pin head 5 passes through the installation hole.

[0019] Preferably in this embodiment, the installation hole and the positioning pin shaft 4 can be in an interference fit, that is, the positioning pin shaft 4 has a certain resistance when extending into the installation hole, and can keep a certain fixing effect after extension, making the positioning pin shaft 4 convenient to insert and remove; or the positioning pin shaft 4 and the installation hole can be connected by threads; or other quick connection and disassembly methods can be used.

[0020] As Figure 1 shown, preferably in this embodiment, both sides of the end of the fixed block 2 are inclined surfaces that are in moving fit with the jaws of the six-jaw chuck 1, so that the fixed block 2 can be closer to the center of the six-jaw chuck 1.

[0022] As Figure 1 shown, preferably in this embodiment, the installation block 3 is an isosceles trapezoidal block, and both sides of the clamping groove are matched with the two base angles of the isosceles trapezoidal block.

[0023] Specifically, since the six-jaw chuck 1 is installed upward on the base, the installation block 3 is clamped into the clamping groove from top to bottom, so that no additional connection mechanism is required between the installation block 3 and the clamping groove. When disassembling the installation block 3, the installation block 3 can be directly taken out of the clamping groove upward.
