[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-4 , a positioning fixture for the processing of inclined ejector rods includes a fixture base 1. A plurality of inclined grooves 3 for placing inclined rods 2 are provided at the top of the fixture base 1, and a positioning member 4 is provided on the side. A fixed block 5 is arranged in the inclined groove 3, and the fixed block 5 is used to fix the inclined rod 2;

[0022] Among them, the positioning member 4 is used to position the inclined rod 2, and it further includes a spring plug rod assembly 6, and the spring plug rod assembly 6 is used to fix the positioning member 4.

[0023] Furthermore, a plurality of the inclined grooves 3 are symmetrically arranged, and their inclinations increase or decrease one by one in the same direction. A block 31 is provided at the end face of the inclined groove 3, and a threaded hole is provided beside the block 31. The inclined rods 2 are placed on both sides of the inclined groove 3.

[0024] It is worth mentioning that by providing the inclined grooves 3 with different inclinations, the inclined rods 2 can be processed with different inclinations, and normally, a pair of the inclined rods 2 can be fixed by one fixed block 5 in one inclined groove 3;

[0025] Among them, the block 31 has a certain height to ensure that the fixed block 5 can be made to contact the block 31 by sliding the fixed block 5, so that the locking bolt 52 can be quickly tightened.

[0026] Furthermore, the fixed block 5 has a wedge-shaped structure. One side of the fixed block 5 can abut against the abutting block 31, and a stepped hole 51 corresponding to the threaded hole is formed in its end face at this position. A locking bolt 52 is threadedly connected in the stepped hole 51. The locking bolt 52 is threadedly connected with the threaded hole. The fixed block 5 is arranged between the two inclined rods 2 on both sides and can abut against the inclined rods 2 tightly.

[0027] It should be noted that the reason for using the wedge-shaped structure of the fixed block 5 is that by pressing down and fixing the fixed block 5, the fixed block 5 abuts against the inclined rod 2 tightly, so as to cooperate with the inner side face of the inclined groove 3 to fix the inclined rod 2.

[0028] More specifically, the positioning member 4 includes a connecting rod 41 slidably connected to both sides of the end face of the jig base 1 through a chute. One end of the connecting rod 41 is provided with a convex portion 42, and a first spring 43 is sleeved on the periphery. Both ends of the first spring 43 are fixedly connected to the convex portion 42 and the inner side face of the chute respectively. The other ends of a pair of connecting rods 41 are fixedly connected with a positioning plate 44, and the positioning plate 44 can abut against the inclined rod 2.

[0029] Specifically, according to the length of the inclined rod 2 to be processed, the positioning plate 44 is pulled and fixed, and then the length of the inclined rod 2 is positioned through the positioning plate 44, which is convenient for improving the accuracy of the processing of the inclined rod 2;

[0030] Moreover, after unlocking the positioning plate 44, under the elastic support of the first spring 43, the positioning plate 44 can quickly return to its original position without hindering the operation.

[0031] Generally speaking, the spring plug rod assembly 6 includes a plug rod 61. A support plate 62 is fixedly installed on the end face of the jig base 1. The plug rod 61 is slidably connected with the support plate 62 and is respectively provided with a baffle 63 and an unlocking portion at both ends. A second spring 64 is sleeved on the end of the plug rod 61. Both ends of the second spring 64 are fixedly connected to the baffle 63 and the side face of the support plate 62 respectively.

[0032] Finally, a plurality of card slots are formed in the end of the connecting rod 41, and the plug rod 61 is inserted into the card slots.

[0033] By inserting the plug rod 61 into the card slots, the position of the positioning plate 44 is adjusted, which is convenient for adapting to inclined rods 2 of different lengths.

[0034] Working method: When working, the inclined rod 2 is placed in the slope groove 3 and contacts the inner side of the slope groove 3, and the insertion rod 61 is pulled out of the slot by the unlocking member, and then the positioning plate 44 is pulled to a suitable position. When the unlocking member is released, the insertion rod 61 is driven by the second spring 64 to be inserted into the slot to fix the positioning plate 44;

[0035] Then, place the fixing block 5 in the slope groove 3 and push the fixing block 5 until it contacts the blocking block 31. At this time, the threaded hole is aligned with the step hole 51 and the fixing block 5 is fastened by the locking bolt 52. The fixing block 5 is squeezed downward to fix the diagonal rod 2.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
