Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the fixture comprises a fixture seat 1, a left stop block 2, a right stop block 3, a gasket 4, a fixing bolt 5, a sliding groove 6, a front V-shaped block 7, a rear V-shaped block 8, a V-shaped groove 9, a front stop block 10, a rear stop block 11, a compression bolt 12, a chip groove 13, a gear shifting pin 14 and a milling cutter 15.
Example 1:
the utility model provides a milling fixture of a plurality of cylinder work pieces of clamping once, is shown as attached figure 1 basically, includes anchor clamps seat 1, is fixed with left dog 2 and right dog 3 through fixing bolt 5 on the anchor clamps seat 1, and the top of left dog 2 and right dog 3 all is equipped with the counter bore, is equipped with packing ring 4 in the counter bore, and packing ring 4 is located the below of fixing bolt 5's head, can improve fixed stability.
As shown in fig. 2, the heights of the left stop block 2 and the right stop block 3 are both higher than the height of the clamp seat 1, the top of the right side surface of the left stop block 2 protrudes rightwards, and the top of the left side surface of the right stop block 3 protrudes leftwards; a gap is left between the protruding part of the left block 2 and the protruding part of the right block 3. Therefore, a T-shaped sliding groove 6 is formed between the protruding portion of the left stopper 2, the protruding portion of the right stopper 3, and the top surface of the jig base 1.
Still include the fixed group that the multiunit can slide along 6 length direction of spout, the quantity of fixed group can set up according to actual need, prefers 8 groups in this embodiment. Each group of fixed groups comprises a front V-shaped block and a rear V-shaped block, the bottoms of the front V-shaped block and the rear V-shaped block are both in a T shape matched with the sliding groove 6, and therefore the front V-shaped block and the rear V-shaped block can transversely slide in the sliding groove 6. And one side of the front V-shaped block opposite to one side of the rear V-shaped block is provided with a V-shaped groove 9.
Referring to fig. 3, a front stop block 10 is disposed on the left side of the fixture seat 1, a rear stop block 11 is disposed on the right side of the fixture seat 1, and both the front stop block 10 and the rear stop block 11 are higher than the fixture seat 1. The front stop block 10 and the rear stop block 11 are fixed on the clamp seat 1 through the fixing bolt 5, and the fixing bolt 5 in the embodiment selects an inner hexagon bolt. The top of the front stop block 10 and the top of the rear stop block 11 are also provided with counter bores, gaskets 4 are arranged in the counter bores, and the heads of the fixing bolts 5 are positioned above the gaskets 4.
Still include one run through backstop 11 and with backstop 11 threaded connection's clamp bolt 12, the left end of clamp bolt 12 is fixed with the flexible tight piece of clamp, the preferred rubber piece of flexible tight piece of clamp in this embodiment. In the flexible clamping block sliding groove 6, the flexible clamping block can be abutted against the rear V-shaped block on the right side.
The specific implementation process is as follows:
the milling of flat squares on both sides of the top of the shift pin 14 will now be explained.
When the gear shifting pin 14 is clamped, the pressing bolt 12 is firstly rotated, so that the pressing bolt 12 exits the rear stop block 11 rightwards, and the front V-shaped block and the rear V-shaped block slide rightwards, so that a certain gap exists between the front V-shaped block and the rear V-shaped block of each fixed group. The shift pins 14 are then placed in the V-grooves 9 of the front and rear V-blocks of each fixed group. After the gear shifting pin 14 is placed, the hold-down bolt 12 is rotated reversely, so that the hold-down bolt 12 drives the flexible abutting block to move leftwards, and pushes the front V-shaped block, the rear V-shaped block and the gear shifting pin 14 to move leftwards. And stopping rotating the compression bolt 12 until the front V-shaped block on the left side abuts against the front stop block 10. The shift pin 14 is now clamped by the front and rear V-blocks. When milling two flat squares on the shift pin 14, two disc mills 15 are arranged on both sides of the shift pin 14, so that the two flat squares can be milled on the shift pin 14 at the same time.
Example 2:
During the milling process, a large amount of chips are generated, and when the chips fall into the chute 6, the chips slide along the inclined chute 6 and are discharged from the chip discharge groove 13. And because the structure setting of preceding V type piece and back V type piece can make the bottom of preceding V type piece and back V type piece not paste with the bottom of spout 6, consequently can realize that spout 6 is to depositing and the water conservancy diversion of piece, the derivation of the piece of being convenient for.
For those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the patent and the practicability of the patent.
