Example one

The embodiment is basically as shown in the attached figure 1: connecting hole ream flat clamp, including workstation 1 and with 1 fixed connection's of workstation limiting plate 4, as shown in fig. 3, set up the locating hole 5 that is used for fixing a position the connecting hole of product on the limiting plate 4, locating hole 5 is equipped with two in this embodiment, telescopic hole 6 has still been seted up on the limiting plate 4, telescopic hole 6 is located between two locating holes 5, as shown in fig. 1, two holding tanks 7 have been seted up on the workstation 1, two holding tanks 7 respectively with two coaxial settings of locating hole 5, the setting of holding tank 7 can avoid workstation 1 to produce the interference to the vertical movement of ream cutter, block.

As shown in fig. 1, a hydraulic corner cylinder 9 for pressing a product is fixedly mounted on the workbench 1 through a bolt, a pressing arm of the hydraulic corner cylinder 9 can rotate 180 degrees, and the hydraulic corner cylinder 9 is in the prior art and is not described herein again. The top end of the hydraulic corner cylinder 9 extends out of the telescopic hole 6, in the embodiment, the workbench 1 is provided with the mounting groove 8, the mounting groove 8 and the telescopic hole 6 are arranged in a vertically opposite mode, and the cylinder body of the hydraulic corner cylinder 9 is located in the mounting groove 8.

Be equipped with the material unit of pressing that is used for compressing tightly the product on workstation 1, hydraulic pressure corner jar 9 can compress tightly the both ends about the product respectively with pressing the material unit, the material unit is equipped with two in this embodiment, two press the left and right sides that the material unit symmetry set up at limiting plate 4, the material unit all includes compressing tightly cylinder 12 in this embodiment, the clamp plate 11 and the depression bar 10 that mutually perpendicular set up, clamp plate 11 all is located limiting plate 4's top, depression bar 10 is located limiting plate 4's the left and right sides respectively, compressing tightly cylinder 12 is located workstation 1, be equipped with two standing grooves 13 on workstation 1 in this embodiment, compressing tightly cylinder 12 is located two standing grooves 13 respectively, the output shaft that compresses tightly cylinder 12 stretches out the top of workstation 1, and depression bar 10 all with compressing tightly cylinder 12's output shaft welded fastening.

As shown in fig. 3, six fixing holes 25 are formed in the limiting plate 4, three fixing holes 25 are in a group, three fixing holes 25 in each group are distributed at intervals, and two groups of fixing holes 25 are respectively located on the front side and the rear side of the positioning hole 5.

As shown in fig. 2, in this embodiment, the arc notch 110 is provided at the opposite end of the pressing plate 11, the arc notch 110 is concentrically disposed with the positioning hole 5, and the radius of the arc notch 110 is greater than the rotation radius of the countersink when rotating, so as to avoid the interference between the pressing plate 11 and the countersink, and to enable the pressing plate 11 to effectively compress the product.

When in use, the limiting plate 4 is fixedly connected with the top end of the workbench 1 through a bolt, then a product to be processed is placed on the limiting plate 4, the positioning hole 5 on the limiting plate 4 plays a role in positioning the product, so that the connecting hole on the product is just opposite to the positioning hole 5 on the left part, then the pressing cylinder 12 at the left part on the workbench 1 is driven to work, the output shaft of the pressing cylinder 12 moves downwards so that the pressing plate 11 presses and fixes the left part of the product, simultaneously, the hydraulic corner cylinder 9 is driven to work, so that the pressure arm of the hydraulic corner cylinder 9 tightly presses and fixes the right part of the product, the product is fixed at the moment, in the actual use process, the machine tool is required to control the countersink to move up and down and drive the countersink to rotate so as to ream a connecting hole of a product, therefore, after the product is fixed, the countersink can be controlled to perform countersink plane processing on the connecting hole of the product.

When the countersink is used for processing a product, the next product to be processed is placed at the right part of the limiting plate 4, the connecting hole of the product is just opposite to the positioning hole 5 at the right part of the limiting plate 4, then the pressing plate 11 at the right part of the driving workbench 1 downwards compresses the product, and therefore the product can be processed on the same workbench 1 while the product is installed and positioned on another product.

After finishing the processing of the ream plane of the product positioned at the left part of the limiting plate 4, the pressing plate 11 at the left part is moved upwards, meanwhile, the pressing arm of the hydraulic corner cylinder 9 is separated from the product and rotated by 180 degrees, then the pressing arm of the hydraulic corner cylinder 9 is moved downwards to compress the product positioned at the right part of the limiting plate 4, at the moment, the ream cutter can be driven to perform the processing of the ream plane of the product arranged at the right part of the limiting plate 4, then the processed product positioned at the left part of the limiting plate 4 is taken out, and a new product to be processed is placed again to wait for processing.

In the embodiment, the next product is installed and positioned without waiting for the completion of the product processing, so that the method is suitable for batch processing. In addition, the arc notch 110 is formed in the pressing plate 11 in this embodiment, so that interference between the countersink and the pressing plate 11 can be avoided, the countersink can smoothly process a product, and the pressing plate 11 can effectively compress the product.

Example two

As shown in fig. 4, the difference between the connecting hole spot-facing jig and the first embodiment is: each locating hole 5's the left and right sides all is equipped with two reference columns 24 in this embodiment, and reference column 24 all can also can dismantle with limiting plate 4 and be connected in this embodiment by fixed connection, and reference column 24 can dismantle with limiting plate 4 in this embodiment and be connected, and is specific: four threaded holes are formed in the limiting plate 4, and the four positioning columns 24 are in threaded connection with the four threaded holes respectively.

During the use, when being equipped with the product in two holes to the bottom and processing, should design according to the reference column 24 that the hole site of product bottom set up on to limiting plate 4, make the hole of product bottom can be smooth insert on the reference column 24.

The setting of reference column 24 can play more accurate location effect to the product, and can play the horizontal restriction effect to the product, avoids the product removal appearing when carrying out ream plane processing to the product to improve the processingquality to the product.

When the product bottom of treating processing does not have the hole, with reference column 24 back-out from limiting plate 4, can make limiting plate 4's surfacing like this to avoid putting the production of product and hindering and lead to the product to place the unevenness.

The above description is only an example of the present invention, and the detailed technical solutions and/or characteristics known in the solutions are not described too much here. It should be noted that, 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 implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
