Description

Technical Field

[0001] The utility model belongs to the technical field of transmission shaft processing, and in particular relates to a positioning tool for flange fork drilling processing. Background Art

[0002] The flange fork is an important component of the drive shaft, which includes an upper fork ear and a connecting flange at the bottom. During the production and processing, in order to achieve its installation and power transmission during actual use, it is necessary to open an ear hole at the center of the upper end of the fork ear, so as to achieve the matching connection between it and the cross universal joint through the ear hole. However, during the drilling process of the flange fork ear hole, due to the relatively simple overall structure of the existing positioning tooling, inaccurate positioning problems are prone to occur. Moreover, when the existing positioning tooling is actually used, since there is no auxiliary component for limiting the flange fork, it is easy to cause the flange fork to shake and displace due to vibration during the drilling process, and then the shaking and displacement of the flange fork affects the accuracy of the ear hole drilling process. Therefore, in order to solve the above problems, it is necessary to develop a positioning tool for flange fork drilling processing that is convenient in positioning operation and has good use effect. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a positioning tool for flange fork drilling processing which has convenient positioning operation and good use effect.

[0004] The object of the utility model is achieved as follows: a positioning tool for flange fork drilling processing, comprising a mounting base plate and a control box, the mounting base plate as a whole is horizontally arranged, four through holes are vertically arranged at the four corners of its upper surface, a positioning groove is arranged in the middle of the upper surface, fixing bolts are passed through the through holes, four positioning rods are evenly arranged around the positioning groove, the positioning rods are iron products, are vertically arranged as a whole, and the lower ends are vertically fixedly connected to the upper surface of the mounting base plate, the distance intervals between the four positioning rods are the same as the distance intervals between the four connecting holes on the flange surface in the flange fork design drawing, and a limiting assembly is set above the two positioning rods on the same side, the limiting assembly is longitudinally arranged as a whole, and the front and rear ends of the lower surface are both provided with grooves matching the positioning rod structure, and the matching sleeve connection with the positioning rod is realized through the groove, and an electromagnet is fixedly arranged on the bottom surface of the groove, the control box is located on the left side of the upper surface of the mounting base plate, and the electromagnet is electrically connected to the control box through a wire.

[0005] An auxiliary pick-and-place block is fixedly arranged in the middle of the upper end of the outer side surface of the limiting component.

[0006] The upper end of the positioning rod is in a frustum shape, and its diameter gradually increases from top to bottom.

[0007] A calibration groove is vertically arranged in the middle of the front end surface of the installation base plate.

[0008] The beneficial effects of the utility model are as follows: the utility model evenly and vertically arranges four positioning rods around the positioning groove. When in use, the positioning rods are used to fit the connecting holes on the surface of the flange in the flange fork to be processed, so as to realize the positioning and placement of the flange fork above the mounting base; by setting a limit assembly, a groove and an electromagnet, after the flange fork is positioned and placed above the mounting base, the limit assembly is placed above the flange in the flange fork as a whole, and the fitting fitting between the groove and the positioning rod is realized. Then, the power circuit of the electromagnet is turned on, and the magnetic attraction of the electromagnet on the iron positioning rod is used to make the limit assembly generate downward pressure on the flange fork. At this time, the downward pressure of the flange fork flange by the limit assembly is combined with the supporting effect of the mounting base plate to realize the pressurized limiting of the flange fork. With this structure, the problem of affecting the drilling accuracy due to the shaking and displacement of the flange fork during the subsequent drilling process can be avoided; in general, the utility model has the advantages of convenient positioning operation and good use effect.

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a positioning tool for flange fork drilling processing includes a mounting base plate 1 and a control box 2. The mounting base plate 1 is arranged horizontally as a whole, and through holes 11 are vertically arranged at the four corners of its upper surface. A positioning groove 12 is arranged in the middle of the upper surface. A fixing bolt 13 is passed through the through hole 11. Four positioning rods 14 are evenly arranged around the positioning groove 12. The positioning rods 14 are made of iron and are arranged vertically as a whole. The lower ends of the positioning rods 14 are vertically fixedly connected to the upper surface of the mounting base plate 1. The distance between the four positioning rods 14 is the same as that of the flange fork. In the design drawing of the flange fork, the distances between the four connection holes on the surface of the flange are the same, and a limit assembly 3 is installed above the two positioning rods 14 on the same side. The limit assembly 3 is arranged longitudinally as a whole, and the front and rear ends of its lower surface are provided with grooves 31 that match the structure of the positioning rod 14, and the matching connection with the positioning rod 14 is achieved through the groove 31, and an electromagnet 32 ​​is fixedly provided on the bottom surface of the groove 31. The control box 2 is located on the left side of the upper surface of the mounting base plate 1, and the electromagnet 32 ​​is electrically connected to the control box 2 through a wire.

[0016] An auxiliary pick-up and placement block 33 is fixedly arranged in the middle of the upper end of the outer side surface of the limit component 3. The auxiliary pick-up and placement block 33 can increase the convenience of the pick-up and placement operation of the limit component 3; the upper end of the positioning rod 14 is truncated cone-shaped, and its diameter gradually increases from top to bottom. By using this structure, the smoothness of the fitting and sleeve connection between the positioning rod 14 and the connecting hole on the surface of the flange in the flange fork can be increased; a calibration groove 15 is vertically arranged in the middle of the front end surface of the mounting base plate 1. The calibration groove 15 can be used to facilitate the calibration of the installation position of the mounting base plate 1 on the drilling equipment, thereby increasing the convenience of subsequent fixed installation by fixing bolts 13.

[0017] When the utility model is used, first, the installation position of the installation base plate 1 on the drilling equipment is calibrated through the calibration groove 15, so that the through holes 11 at the four corners thereof correspond to the mounting holes on the drilling equipment, and then the fixing bolts 13 are passed through the through holes 11 and the mounting holes in sequence, so as to realize the fixed connection between the installation base plate 1 and the drilling equipment; then, the flange fork to be drilled is positioned and placed above the installation base 1 by using the matching sleeve between the four positioning rods 14 and the four connecting holes on the surface of the flange in the flange fork to be processed; after completing the positioning and placement of the flange fork, the limit assembly 3 is placed above the flange in the flange fork as a whole, and the groove 31 is realized with the positioning rod 14. The matching sockets are finally turned on the power circuit of the electromagnet 32. The magnetic attraction of the electromagnet 32 ​​on the iron positioning rod 14 after being energized can make the limit assembly 3 move downward as a whole and generate downward pressure on the flange fork. At this time, the downward pressure of the flange fork flange by the limit assembly 3 is combined with the supporting effect of the mounting base 1 to achieve pressurized limiting of the flange fork, thereby avoiding the problem of affecting the drilling accuracy due to the shaking and displacement of the flange fork during the subsequent drilling process. After completing the above operations, the flange fork can be drilled by operating the drilling equipment. In general, the utility model has the advantages of convenient positioning operation and good use effect.
