[0029] The utility model provides a fixing fixture. Figures 1 to 3 A specific embodiment of the fixing fixture provided by the utility model.

[0030] Reference Figures 1 to 3 , the fixing fixture comprises:

[0031] A base 1, wherein the base 1 is provided with a plurality of first limiting blocks 11, wherein the plurality of first limiting blocks 11 enclose a limiting cavity 12 for limiting the flange 3, and the base 1 is provided with a groove 13 corresponding to the flange hole 31 of the flange 3; and

[0032] A gland 2 is provided corresponding to the limiting cavity 12, the gland 2 is connected to the base 1 by screws 21 to fix the flange 3 between the gland 2 and the base 1, and the gland 2 is provided with a clamping block 22 for clamping with the flange hole 31 and the groove 13;

[0033] A second limiting block 14 is disposed in the groove 13 , and a limiting groove 23 cooperating with the second limiting block 14 is formed through the pressure cover 2 .

[0034] The utility model can limit the flange 3 on the inside by clamping the clamping block 22 with the groove 13 and the flange hole 31 of the flange 3, and cooperate with the first limiting block 11 to limit the flange 3 on the outside. When the pressure cover 2 is installed by the screw 21, the relative displacement between the flange 3 and the base 1 can be effectively avoided, and the positioning accuracy of the flange 3 is guaranteed. The cooperation of the second limiting block 14 and the limiting groove 23 can avoid rotation of the pressure cover 2 during installation, and ensure the stability of the pressure cover 2 pressing the flange 3.

[0035] The second stop block 14 is configured as an arcuate wedge block, and the stop groove 23 is an arcuate groove corresponding to the shape of the arcuate wedge block, and the arcuate groove penetrates the gland 2 toward the plane side thereof. The second stop block 14 and the stop groove 23 are configured in an arcuate shape, so that the contact area between the second stop block 14 and the stop groove 23 is large, so that when the screw 21 is tightened, the pressure generated by the second stop block 14 on the stop groove 23 is small, and deformation of the second stop block 14 and the gland 2 can be avoided. The arcuate groove is configured to penetrate toward one side of the gland 2, and this configuration facilitates the placement of the gland 2 above the flange 3.

[0036] A positioning groove 33 is provided on one side of the flange 3 close to the base 1; the base 1 is provided with a positioning column 15 for aligning with the positioning groove 33. On the one hand, the alignment accuracy between the flange 3 and the processing equipment can be ensured by the cooperation between the positioning column 15 and the positioning groove 33; on the other hand, based on the limiting of the flange 3 by the first limiting block 11 and the clamping block 22, the flange 3 can be further limited by the cooperation between the positioning column 15 and the positioning groove 33.

[0037] The base 1 and the positioning column 15 are provided with avoidance holes 16 corresponding to the processing position 32 of the flange 3. The processing equipment needs to perform processing operations such as drilling and tapping on the processing position 32 of the flange 3. By providing the avoidance holes 16, it is possible to avoid interference between the processing equipment and the base 1 during processing, thereby preventing damage to the base 1 or the processing equipment.

[0038] The first limiting block 11 is chamfered at one side away from the base 1. The chamfer of the first limiting block 11 can guide the flange 3, so that the flange 3 is conveniently placed in the limiting cavity 12.

[0039] The second stopper 14 is chamfered on one side close to the gland 2. The chamfer of the second stopper 14 can guide the gland 2, so that the gland 2 is placed on the flange 3 and the second stopper 14 corresponds to the stopper groove 23.

[0040] The gland 2 is provided with a countersunk hole 24, the base 1 is provided with a threaded hole 17 corresponding to the countersunk hole 24, and the screw 21 passes through the countersunk hole 24 and is connected to the threaded hole 17. By providing the countersunk hole 24, the screw 21 can be installed after the threaded hole 17, and the head of the screw 21 is located in the countersunk hole 24, thereby avoiding interference between the processing equipment and the head of the screw 21.

[0041] The number of the first limit blocks 11 is at least four. When the number of the first limit blocks 11 is four, two of the first limit blocks 11 are arranged on opposite sides of the flange 3 in one direction, and the other two first limit blocks 11 are arranged on opposite sides of the flange 3 in another direction, so that the four first limit blocks 11 can limit the horizontal displacement of the first limit blocks 11.

[0042] The screw 21 is provided with a hexagon socket hole. The hexagon socket hole is used for installing a hexagon socket wrench, so that the screw 21 can be screwed with the hexagon socket wrench, which is convenient for operation.

[0043] The utility model also proposes a processing equipment, which includes a fixed fixture. The specific structure of the fixed fixture refers to the above embodiment. Since the processing equipment proposed by the utility model includes all schemes of all embodiments of the above fixed fixture, it has at least the same technical effect as the fixed fixture, which will not be elaborated here one by one.

[0044] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
